Description

The present invention relates to a device for removing and winding continuous label paper.

As a scrap winding device for continuous label paper, after printing characters and patterns on continuous label paper, the label base material and adhesive layer of continuous label paper are pulled out into a predetermined shape, and unnecessary scraps are peeled off from the mount. It is known that the paper is wound around the winding shaft. It is conceivable that it is difficult to secure the strength of the lees extracted in a predetermined shape, and the lees are cut before reaching the lees winding shaft.
For this reason, it is not preferable to apply a strong tension to the lees from the time when the lees are peeled off from the mount until the lees take-up shaft is reached.

Here, the tension applied to the lees varies according to the change in the roll diameter of the lees wound around the lees winding shaft if the torque of the lees winding shaft is constant. Further, the tension applied to the debris affects the torque fluctuation of the servomotor due to the mechanical loss of the mechanical system and the acceleration / deceleration of the winding speed. Therefore, fluctuations in tension during winding of the lees also cause cutting of the lees.
Further, the lees are punched into a predetermined shape. For this reason, the lees have the property of shrinking in the direction perpendicular to the direction of tension (the width direction of the lees) when tension is applied in the transport direction. Here, when the predetermined shape is a circular or amorphous label other than a rectangular shape, it is difficult for the amount of shrinkage of the lees to be constant. Therefore, it is conceivable that the load is concentrated on the portion where the amount of shrinkage of the lees is large and undulates in the direction perpendicular to the direction of tension. In this state, if the tension of the lees fluctuates, the lees are likely to be cut.

In particular, in the section from when the slag is peeled off from the mount to when it reaches the slag take-up shaft (hereinafter referred to as the slag path), the amount of shrinkage in the width direction of the slag increases and the place where the load concentrates increases. In some cases. Further, when the amount of shrinkage in the width direction of the lees is large, there are large and small roll diameters of the lees that have been wound up, and the lees that are wound up at the large roll diameters have high tension.
The lees are easily cut at places where the amount of shrinkage in the width direction of the lees is large and the load is concentrated, or where the lees winding diameter is large and the tension is high.

Some of the lees winding devices for continuous label paper bring the outer periphery of the lees wound around the lees winding shaft into pressure contact with the lees roll drive roller in order to suppress the cutting of the lees. The lees roll drive roller rotates synchronously at the transport speed of continuous label paper.
The adhesive layer of the lees is attached to the lees winding shaft by pressure-contacting the outer periphery of the lees with the lees roll drive roller. In this state, the lees take-up shaft is driven and rotated to continuously wind the lees in a roll shape. According to this continuous label paper pomace take-up device, the dregs are wavy in the width direction, the lees path that tends to cause the above obstacles can be remarkably shortened, and the lees can be wound without applying tension to the lees. (For example, see FIGS. 2 and 4 of Patent Document 1).

On the other hand, in the apparatus disclosed in FIGS. 1 and 3 of Patent Document 1, the residue portion is removed from the continuous label paper to which a large number of labels in which both the label base material and the adhesive layer are punched out into a predetermined shape are attached. Is peeled off and wound up with a lees winding shaft. At this time, the outer peripheral surface of the lees roll is formed by the lees winding shaft pulling out the lees and winding the lees.
In this device, in order to prevent the outer peripheral surface of the lees roll from interfering with the peeling roller, the transport path of the lees from the peeling roller to the lees winding shaft is made longer than the maximum radius of the lees roll.

Japanese Unexamined Patent Publication No. 2000-355459

By the way, when the drawing area of the continuous label paper is large, the shape of the outer peripheral surface of the lees roll wound around the lees winding shaft becomes distorted. However, in the apparatus disclosed in FIGS. 2 and 4 of Patent Document 1, vibration is generated because the distorted slag roll is brought into pressure contact with the slag roll drive roller to rotate. In general, the lees with a large punching area depends on the type of continuous label paper, but because the area of the lees is small, the shape of the lees after the product label is pulled from the continuous label paper can be maintained. There is a problem that it is unstable, vibrates and easily cuts. Further, if this vibration is prevented, there is a problem that the cake winding speed cannot be increased.

Here, the debris of the deformed label, that is, a complicated and relatively large debris, may be peeled off from the debris portion of the label supported by the thin horizontal frame and the vertical frame and wound up by the lees winding shaft.
When the punching shape is complicated like this deformed label, or when the vertical frame in the winding direction (transporting direction) of the scraps is thin and the number is small, the hoisting force is transmitted only to a part of the scraps. There is a problem that the peeling and picking up of the shavings by the peeling roller may not be performed smoothly.

Further, as in the apparatus disclosed in FIGS. 1 and 3 of Patent Document 1, especially when the transport path of the slag from the peeling roller to the slag take-up shaft is set longer than the maximum radius of the slag roll. In the case of debris removal of deformed labels, the horizontal frame of the slag is twisted and the slag is reversed due to the vibration of the slag and the tension difference between the left and right in the transport process, and the vertical frame of the slag. There is a problem that twisting occurs in the slag and the slag breaks easily.

The present invention has been made in view of the above circumstances, and in a process of separating continuous label paper into a label product and a pomace and raising the dregs, the debris to be conveyed is guided to cause slack in the lees. It is intended to achieve the purpose of preventing wobbling. Further, the present invention aims to achieve the object of preventing the occurrence of twisting, inversion and cutting of the lees in the transport path of the lees, and adjusting the unevenness of the outer peripheral surface of the lees roll.

Further, the present invention aims to achieve the object of eliminating the vibration of the lees from the outer peripheral surface of the lees roll and making it possible to wind the lees with a stable tension.
Further, the present invention aims to achieve the object of preventing the lees from being cut and improving the winding speed of the lees by smoothly peeling and raising the lees in the peeling roller. ..

In order to solve the above problems, the continuous label paper punching and winding device of the present invention conveys the continuous label paper that has been half-pulled and separates the stripped product attached to the mount and the stripped waste. It is a continuous label paper extraction and winding device equipped with a peeling roller.

In the continuous label paper pomace winding device of the present invention, the dregs holding roller is provided so as to be swingable around the axis of the peeling roller, and the outer peripheral surface of the dregs wound around the dregs winding shaft. It is possible to provide a slag holding transfer unit that presses the slag holding roller toward the slag holding roller.

The lees winding device for continuous label paper of the present invention may be provided on the drive side of the lees winding shaft and may include a tension adjusting unit for adjusting the tension applied to the lees.

The continuous label paper pulling and winding device of the present invention adjusts the axial center position of the peeling roller in a direction orthogonal to the direction connecting the axial center of the peeling roller and the axial center of the waste winding shaft. It is possible to provide a peeling roller position adjusting portion.

According to the present invention, when the lees are wound around the lees winding shaft in a roll shape, the transport of the lees is guided from the peeling roller to the roll of the lees wound around the lees winding shaft by the guide belt. This makes it possible to prevent a phenomenon in which the horizontal frame of the pomace is twisted and the lees are inverted, and a phenomenon in which the vertical frame of the lees is twisted and the lees is broken. At the same time, by smoothly raising the lees, it is possible to prevent cutting of the lees and improve the winding speed of the lees.

Further, when the lees wound around the lees winding shaft in a roll shape is wound, the lees holding roller presses the lees with a constant pressure toward the lees winding shaft by the lees holding transport unit to remove the lees. Can be wound up. Further, the lees can be wound by keeping the transport distance of the lees transported from the peeling roller to the roll of the lees wound around the lees winding shaft constant. This makes it possible to smoothly raise the dregs.

The roll diameter of the slags wound around the slag take-up shaft in a roll shape increases, and in response to this change, the pressing force that presses the slags toward the slag take-up shaft with the slag holding roller is kept constant. The guide belt can stably guide the slag from the peeling roller to the roll of the slag that is wound around the slag take-up shaft. This makes it possible to smoothly raise the dregs.

Further, the lees take-up shaft can be moved in a direction away from the peeling roller based on the roll diameter of the lees taken up by the lees take-up shaft. Therefore, the distance between the outer peripheral surface of the lees wound around the lees winding shaft and the outer peripheral surface of the peeling roller can be kept small. That is, the lees path dimension from the outer peripheral surface of the peeling roller to the outer peripheral surface of the lees can be suppressed to a small size.
As a result, even if the predetermined shape of the punched product is a circle other than a rectangle or an irregular shape, the tension generated in the scraped lees during winding is stabilized to prevent the stripped lees from being cut to the maximum extent. can.
Further, by suppressing the cutting of the lees, the speed at which the lees are wound around the lees winding shaft can be increased. As a result, the printing speed of the continuous label paper can be increased, and the productivity of the punched product can be greatly improved.

Further, by providing the tension adjusting portion on the drive side of the lees winding shaft, the tension applied to the lees removed by winding can be adjusted and kept constant. As a result, it is possible to prevent the lees from being cut due to tension fluctuations during winding, and to wind the lees in a stable state.

Further, the lees holding roller is made to correspond to the change in the roll diameter so that the lees holding roller can be pulled out and come into contact with the outer peripheral surface of the lees. Therefore, the entire outer peripheral surface of the lees can be flattened by the lees holding roller. As a result, the distance between the outer peripheral surface of the lees wound around the lees winding shaft and the outer peripheral surface of the peeling roller can be more preferably maintained. Therefore, the tension generated in the lees during winding can be stabilized more satisfactorily.

Further, by providing the peeling roller position adjusting portion, it is possible to adjust the slag raising position in the peeling roller. As a result, the relative position of the peeling roller in the transport direction of the continuous label paper, that is, the lees raising position can be adjusted so that the peeling roller can smoothly peel and lift the lees. The generated tension can be stabilized more satisfactorily. Further, the relative position of the peeling roller in the transport direction of the continuous label paper, that is, the slag raising position can be adjusted.
Further, it is possible to suppress the cutting of the lees and increase the speed at which the lees are wound around the lees winding shaft. As a result, the printing speed of the continuous label paper can be increased, and the productivity of the punched product can be greatly improved.

Hereinafter, an embodiment of the waste cake winding device according to the present invention will be described with reference to the drawings.
In the figure, reference numeral 10 is a device for removing and winding continuous label paper.

As shown in FIGS. 1 to 3, the continuous label paper stripping and winding device 10 according to the present embodiment includes a frame 12, a winding mechanism 14, a vertical moving mechanism (moving mechanism) 16, and a detecting means 20. A calculation unit 22, a control unit 24, a slag holding and transporting unit 200, and a peeling roller position adjusting unit 220 are provided. Hereinafter, the continuous label paper scraping and winding device 10 will be abbreviated as “pulling residue winding device 10”.

As shown in FIGS. 2 to 4, the continuous label paper 30 is conveyed to the debris winding device 10 as shown by the arrow A. In the continuous label paper 30, the label base material is adhered to the mount 31 via an adhesive layer (not shown). On the continuous label paper 30, characters and patterns are printed on the label base material in the printing process provided on the upstream side in the transport direction of the waste cake winding device 10 or in a separate line device.
After the printing process, in the processing process, the label base material and the adhesive layer are half-punched with a punched product (hereinafter referred to as a label) 34 by an engraving blade, a corroded blade (that is, a flexible die), or a laser beam. .. In the half punching process, the label base material and the adhesive layer of the continuous label paper 30 are processed so as to be bordered in a predetermined shape. That is, the mount 31 is not processed by the half punching process.
By the half punching process, the label 34 and the scrap 36 are formed from the label base material.

After the continuous label paper 30 is subjected to the half punching process of the label 34, the strip 36 is peeled from the mount 31 of the continuous label paper 30 by the peeling roller 147. As a result, the continuous label paper 30 is separated into the label 34 attached to the mount 31 by the adhesive layer and the debris 36 peeled from the mount 31 by the peeling roller 147. The label 34 attached to the mount 31 is conveyed together with the mount 31 in the direction of arrow B.

On the other hand, the scrap 36 peeled from the mount 31 is wound about half a circumference of the outer peripheral surface 147a of the peeling roller 147. After that, the shavings 36 are separated from each other in the width direction of the shavings 36, which is the axial direction of the peeling roller 147, in the transport path from the peeling roller 147 to the slag take-up shaft 51 at the upper position. It is spread out and guided and supported on a transport guide conveyor formed by a plurality of guide belts (round belts) 145 wound around a peeling roller 147. The slag 36 is guided by the transport path in this way, and is transported to the slag take-up shaft 51 without causing slack or twisting.

The transported slag 36 is attached to the paper tube 64 of the slag take-up shaft 51 and is wound into a roll by the rotation of the slag take-up shaft 51.
Hereinafter, the slag 36 wound in a roll shape on the slag take-up shaft 51 is referred to as a “slag roll 37”.

Hereinafter, the configuration of the waste cake winding device 10 will be described with reference to FIGS. 1 to 10.
As shown in FIGS. 1 to 3 and 8, the frame 12 of the slag take-up device 10 supports a take-up mechanism 14, a vertical movement mechanism 16, a slag holding and conveying unit 200, and a detection means 20. .. Further, the transport roller 41, the nip roller (or nip roller) 42, the guide roller 43, the conversion roller 44, the label transfer roller 45, the re-crimp receiving roller 46, and the re-crimp roller 47 are rotatably supported on the frame 12. There is. The transport roller 41 sandwiches and conveys the continuous label paper 30 together with the nip roller (or nip roller) 42. The re-crimp receiving roller 46 sandwiches and conveys the continuous label paper 30 together with the re-crimping roller 47.

The transport roller 41, the nip roller (or nip roller) 42, the guide roller 43, the conversion roller 44, the label transfer roller 45, the re-crimp receiving roller 46, and the re-crimp roller 47 are, for example, upstream of the transport path of the continuous label paper 30. It is provided in order from the beginning to form a transport path for the continuous label paper 30. In FIGS. 1 and 2, the transport path of the continuous label paper 30 is partially omitted.
Further, as will be described later, the peeling roller 147 is rotatably supported on the frame 12. In the figure, the frame 12 and the like may be partially omitted for the sake of explanation.

As shown in FIG. 3, the peeling roller 147 is provided with a label transfer blade 144 at a position at the lowermost end of the outer peripheral surface 147a.
When the continuous label paper 30 is conveyed to the gap between the label transfer blade 144 and the release roller 147, the label transfer blade 144 changes the direction (folds back) of the mount 31 in the continuous label paper 30 from which the scrap 36 is separated. The label 34 attached to the mount 31 is peeled off from the mount 31, and the mount 31 is separated into the conversion roller 44.

A label transfer roller 45 is provided at the tip position of the label transfer blade 144. The label transfer roller 45 is arranged at a position where the label 34 peeled off at the tip position of the label transfer blade 144 can be reattached to the mount 31.
A re-crimp receiving roller 46 and a re-crimping roller 47 are arranged on the downstream side of the label transfer roller 45.

The peeling roller 147 is positioned so that the bottom surface 147 g, which is the lowermost end of the outer peripheral surface 147a, keeps a predetermined gap that does not urge the continuous label paper 30 to the label transfer blade 144 side. As will be described later, the peeling roller 147 is supported by the frame 12 so as to be horizontally movable by the peeling roller position adjusting portion 220.
The peeling roller 147, the label transfer blade 144, the conversion roller 44, and the label transfer roller 45 form a label transfer mechanism.

Further, as shown in FIGS. 1 and 8, a relief hole 48 is formed in the frame 12. The relief hole 48 extends in the vertical direction so that the lees winding shaft 51 can move in the vertical direction.

The take-up mechanism 14 includes a lees take-up shaft 51, a powder clutch (tension adjusting unit) 53, and a first servomotor 55. The Kasu winding shaft 51, the powder clutch 53, and the first servomotor 55 are attached to the moving body 76 of the vertical moving mechanism 16.
The lees winding shaft 51 is rotatably supported by the upper portion 85a of the first table 85 of the moving body 76 via a bearing. The lees winding shaft 51 is provided on the upper side in the substantially vertical direction with respect to the roller center 147b of the peeling roller 147 (see FIG. 2).

Further, the lees winding shaft 51 is formed in a hollow shape having a circular cross section, and a plurality of elongated holes (slits) 57 extending in the axial direction are formed on the outer periphery thereof. A first timing pulley 58 is coaxially attached to the lees winding shaft 51.
A rubber tube is housed inside the lees winding shaft 51 so as to be elastically deformable. A metal claw (hereinafter referred to as a lug) 62 is provided on the outer circumference of the rubber tube. An air flow path is communicated inside the rubber tube. The air flow path communicates with the air supply source via the rotary joint 63.

The air supplied from the air supply source is filled inside the rubber tube through the rotary joint 63 and the air flow path. Therefore, the rubber tube expands radially outward, and the lug 62 projects radially outward from the elongated hole 57 of the lees winding shaft 51. Here, a paper tube 64 (see FIG. 2) is fitted to the lees winding shaft 51. Therefore, the lug 62 protruding from the elongated hole 57 of the lees winding shaft 51 abuts on the inner surface of the paper tube 64, and the paper tube 64 is coaxially fixed to the lees winding shaft 51.
In the embodiment, an example in which the lug 62 is projected outward in the radial direction by using air pressure will be described, but the present invention is not limited to this. As another example, for example, the lug 62 may be mechanically projected outward in the radial direction.
A rotation stopper 65 is attached to the case of the rotary joint 63. The rotation stop bracket 65 is attached to the second table 86 of the moving body 76. Therefore, the rotation of the case of the rotary joint 63 is suppressed by the rotation stop bracket 65.

As shown in FIGS. 7 to 9, a first servomotor 55 is connected to the lees winding shaft 51 via a powder clutch 53. The first servomotor 55 is attached to the lower plate 83 of the second table 86. The plate 83 is attached to the lower part of the second table 86.
Specifically, a plurality of first elongated holes 86a are formed in the lower part of the second table 86 so as to extend in the vertical direction. A plate 83 is attached to the lower part of the second table 86 by a first bolt 81 penetrating a plurality of first elongated holes 86a. The first servomotor 55 is attached to the lower part of the second table 86 of the moving body 76 via the plate 83.
Therefore, the first servomotor 55 can be moved in the vertical direction by loosening the first bolt 81 and moving the plate 83 in the vertical direction. That is, the position of the first servomotor 55 can be adjusted in the vertical direction with respect to the powder clutch 53.
A second timing pulley 66 is coaxially attached to the output shaft of the first servomotor 55.

In the second table 86, the powder clutch 53 is arranged between the first servomotor 55 and the lees winding shaft 51. Here, the second table 86 is formed so that a plurality of second elongated holes 86b extend in the vertical direction at the upper portion. The second bolt 97 is screwed into the pair of connecting members 87 through the plurality of second elongated holes 86b, and the second table 86 can be fixed by tightening the second bolt 97. It has become.
Therefore, the powder clutch 53 can be moved in the vertical direction by loosening the second bolt 97 and moving the second table 86 in the vertical direction. That is, the position of the powder clutch 53 can be adjusted in the vertical direction with respect to the lees winding shaft 51.
The powder clutch 53 is provided on the drive side of the lees winding shaft 51, and is generally used for producing long objects, for example. The powder clutch 53 uses powder (magnetic iron powder) for torque transmission, and has both the smoothness of a fluid clutch and the highly efficient connectivity of a friction plate type clutch.

That is, the powder clutch 53 can be slid smoothly to keep the fluctuation of the tension applied to the residue 36 constant. Further, the set torque of the powder clutch 53 can be changed stepwise according to the roll diameter D (see FIG. 2) of the scrap roll 37. Therefore, by providing the powder clutch 53 on the drive side of the slag take-up shaft 51, the tension applied to the slag 36 of the slag roll 37 can be adjusted and the fluctuation of the tension can be kept constant. This makes it possible to prevent the shavings 36 from being cut due to fluctuations in the tension applied to the shavings 36.

As shown in FIGS. 2 to 4, in the present embodiment, the rotation speed of the slag take-up shaft 51 is such that the slag 36 is wound when the roll diameter D of the slag roll 37 is the minimum diameter of the paper tube 64. The take-up amount is set to a constant value that is at least the same as or more than the amount of the continuous label paper 30 in the transfer path.
Therefore, the slag 36 is wound around the slag take-up shaft 51 without loosening. On the other hand, when the roll diameter D of the slag roll 37 becomes large, the winding amount of the slag 36 of the slag take-up shaft 51 increases with respect to the transfer amount of the continuous label paper 30 in the transfer path. In this case, since the tension applied to the scrap 36 increases, the set torque of the powder clutch 53 (see FIG. 9) can be adjusted stepwise.

As shown in FIGS. 2, 8 and 9, tension is applied to the slag 36 of the slag roll 37. The tension fluctuates due to a change in the roll diameter D of the scrap roll 37, a mechanical loss of the mechanical system, and a torque fluctuation during acceleration / deceleration of the first servomotor 55. Therefore, by interposing the powder clutch 53 between the slag take-up shaft 51 and the first servomotor 55, the fluctuation of the tension applied to the slag 36 can be kept constant.

Further, the powder clutch 53 also has a structure in which the set torque can be changed stepwise according to the roll diameter D of the slag roll 37 in order to cope with the fluctuation of the roll diameter D of the slag roll 37. That is, the tension applied to the slag 36 varies according to the change in the roll diameter D of the slag roll 37 if the torque of the slag take-up shaft 51 is constant. Therefore, the fluctuation of the tension can be kept constant by changing the set torque of the powder clutch 53 stepwise according to the roll diameter D of the dregs roll 37.

In this way, by providing the powder clutch 53 on the drive side of the dregs take-up shaft 51, the tension applied to the dregs 36 by the dregs can be kept constant. As a result, it is possible to prevent the shavings 36 from being cut due to fluctuations in tension during winding, and the shavings 36 can be wound in a stable state.
The set torque of the powder clutch 53 can be changed on the monitor screen installed in the debris winding device 10.

The powder clutch 53 is attached to the upper part of the second table 86 of the moving body 76. A third timing pulley 68 is coaxially attached to the input shaft of the powder clutch 53. Further, a fourth timing pulley 69 is coaxially attached to the output shaft of the powder clutch 53. The third timing pulley 68 is connected to the fourth timing pulley 69 via the input shaft and the output shaft of the powder clutch 53.

The second timing pulley 66 of the first servomotor 55 is connected to the third timing pulley 68 of the powder clutch 53 via the first timing belt 71. The tension of the first timing belt 71 is suitably adjusted by loosening the plurality of first bolts 81 (see FIG. 7) and moving the first servomotor 55 in the vertical direction.
Further, the fourth timing pulley 69 of the powder clutch 53 is connected to the first timing pulley 58 of the lees winding shaft 51 via the second timing belt 72. The tension of the second timing belt 72 is suitably adjusted by loosening the plurality of second bolts 97 (see FIG. 7) and moving the powder clutch 53 in the vertical direction.

In this state, by rotating the second timing pulley 66 with the first servomotor 55, the rotation of the second timing pulley is transmitted to the third timing pulley 68 of the powder clutch 53 via the first timing belt 71. The rotation of the third timing pulley 68 causes the input shaft of the powder clutch 53 to rotate.
As the input shaft of the powder clutch 53 rotates, the output shaft of the powder clutch 53 rotates. The rotation of the output shaft of the powder clutch 53 causes the fourth timing pulley 69 to rotate. The rotation of the fourth timing pulley 69 is transmitted to the first timing pulley 58 via the second timing belt 72. As the first timing pulley 58 rotates, the slag take-up shaft 51 rotates in the winding direction of the slag 36. As a result, the slag 36 is wound around the paper tube 64 of the slag take-up shaft 51.

Here, the fourth timing pulley 69 and the first timing pulley 58 are formed to have the same number of teeth. Therefore, the rotation speed of the lees winding shaft 51 is the same as the rotation speed of the output shaft of the powder clutch 53. Further, the second timing pulley 66 of the output shaft of the first servomotor 55 and the third timing pulley 68 of the input shaft of the powder clutch 53 have the same number of teeth as the fourth timing pulley 69 of the output shaft of the powder clutch 53. It is formed.

By interposing the powder clutch 53 between the lees winding shaft 51 and the first servomotor 55 in this way, the fluctuation of the tension applied to the lees 36 can be kept constant by the powder clutch 53.
Further, the tension applied to the slag 36 varies according to the change in the roll diameter D of the slag roll 37 when the torque of the slag take-up shaft 51 is kept constant. In order to cope with the fluctuation of the roll diameter D, the set torque of the powder clutch 53 can be changed stepwise according to the roll diameter D of the dregs roll 37.
This makes it possible to prevent the shavings 36 from being cut due to fluctuations in the tension applied to the shavings 36.

The connection of the first servomotor 55, the powder clutch 53, and the lees winding shaft 51 is not limited to the configuration of the embodiment. The lees winding shaft 51 and the first servomotor 55 may be connected via the powder clutch 53.
The winding mechanism 14 is attached to the moving body 76 of the vertical moving mechanism 16.

The moving body 76 is supported by a pair of linear motion guides 75 so as to be movable in the vertical direction.

The mobile body 76 includes a plurality of sliders 84, a first table 85, and a second table 86. The plurality of sliders 84 are movably supported by a pair of linear motion guides 75. Specifically, in the plurality of sliders 84, for example, two sliders 84 are movably supported by one linear motion guide 75 at intervals in the vertical direction, and two sliders are supported by the other linear motion guide 75. The 84 is movably supported at intervals in the vertical direction.
The plurality of sliders 84 are attached to the first table 85. A second table 86 is attached to the first table 85 via a connecting member 87.

That is, the plurality of sliders 84, the first table 85, the connecting member 87, and the second table 86 are integrally attached. Therefore, the plurality of sliders 84, the first table 85, the connecting member 87, and the second table 86 are movably supported by the pair of linear motion guides 75 in the vertical direction. The take-up mechanism 14 is attached to the first table 85 and the second table 86. That is, the winding mechanism 14 is movably supported in the vertical direction by the pair of linear motion guides 75 via the moving body 76. A pair of ball screws 77 are provided on both sides of the moving body 76.

The pair of ball screws 77 are rotatably attached to the frame 12 on both sides of the moving body 76 and at a position farther from the clearance hole 48 than the pair of linear motion guides 75 via the upper and lower bearings 88. .. The pair of ball screws 77 extend in the vertical direction along the clearance hole 48. A nut (not shown) is rotatably supported by the pair of ball screws 77, and the nut is supported by the connecting bracket 92. The connecting bracket 92 is attached to the connecting member 87 (see also FIG. 7).
A pair of driven gears 78 are attached to the lower ends of the pair of ball screws 77. Specifically, one of the pair of driven gears 78 is coaxially attached to one of the pair of ball screws 77. Further, the other of the pair of driven gears 78 is coaxially attached to the other of the pair of ball screws 77. The pair of driven gears 78 are bevel gears.

A pair of drive gears 79 are meshed with the pair of driven gears 78. That is, one of the pair of drive gears 79 is meshed with one of the pair of driven gears 78. Further, the other of the pair of driven gears 78 is meshed with the other of the pair of drive gears 79.
The pair of drive gears 79 are bevel gears and are coaxially attached to the vicinity of both ends of the rotating shaft 89. Both ends of the rotating shaft 89 are rotatably supported by the frame 12 via bearings 91. A fifth timing pulley 93 is coaxially attached to the central portion of the rotating shaft 89. A second servomotor 82 is attached below the rotating shaft 89.

The second servomotor 82 is attached to the frame 12 via the attachment bracket 94. A sixth timing pulley 95 is coaxially attached to the output shaft of the second servomotor 82. The sixth timing pulley 95 of the second servomotor 82 is connected to the fifth timing pulley 93 of the rotating shaft 89 via the third timing belt 96. The tension of the third timing belt 96 is suitably adjusted by moving the second servomotor 82 in the vertical direction.

In this state, by rotating the sixth timing pulley 95 with the second servomotor 82, the rotation of the sixth timing pulley is transmitted to the fifth timing pulley 93 of the rotating shaft 89 via the third timing belt 96. As the fifth timing pulley 93 rotates, the pair of drive gears 79 rotate via the rotation shaft 89.
The rotation of the pair of drive gears 79 causes the pair of driven gears 78 to rotate. The rotation of the pair of driven gears 78 causes the pair of ball screws 77 to rotate. The rotation of the pair of ball screws 77 causes the connecting bracket 92 (that is, the moving body 76) to move in the vertical direction.
The take-up mechanism 14 is attached to the first table 85 and the second table 86 of the moving body 76. When the moving body 76 moves in the vertical direction, the lees winding shaft 51 of the winding mechanism 14 moves in the vertical direction.

As shown in FIGS. 8 and 10, by moving the slag take-up shaft 51 in the vertical direction (direction of arrow C) by the vertical movement mechanism 16, the slag winding corresponds to the change in the roll diameter D of the slag roll 37. The intake shaft 51 can be moved in the vertical direction. That is, the lees winding shaft 51 can be moved by the vertical movement mechanism 16 in a direction away from the peeling roller 147 or in a direction approaching the peeling roller 147.
As a result, the outer peripheral surface 36a of the slag roll 37 and the outer peripheral surface 147a of the peeling roller 147 do not come into contact with each other, and the slag take-up shaft 51 is adjusted to a predetermined interval (distance) r (see FIGS. 12 and 13) described later. It is possible.

As shown in FIGS. 2 to 5, a residue holding and conveying section 200 is provided above the release roller 147 at a lateral position between the release roller 147 and the residue take-up shaft 51.
In FIG. 2, the support portion 12a and the frame 12 and the like on the outside (front side) of the peeling roller 147 and the like are partially omitted.

The slag holding transfer section 200 includes a slag holding roller 142, a guide belt 145, a swinging section 150, and a slag holding air cylinder 153.
The slag holding roller 142 is rotatably attached to a swinging portion 150 that can swing with respect to the roller center 147b of the peeling roller 147. One end of the swinging portion 150 can swing coaxially with the roller center 147b of the peeling roller 147. A slag holding roller 142 having an axis parallel to the axis of the peeling roller 147 is rotatably attached to the other end of the swinging portion 150.

As the rocking portion 150 can swing with respect to the roller center 147b of the peeling roller 147, the cake holding roller 142 with respect to the roller center 147b of the peeling roller 147 as shown by an arrow S in FIG. Therefore, it is possible to swing along a predetermined arc defined by the length dimension of the swing portion 150.
The length dimension of the swing portion 150 is arranged so that the slag holding roller 142 can always come into contact with the outer peripheral surface 36a of the slag roll 37 in accordance with the change in the roll diameter D of the slag roll 37.

The peeling roller 147 and the slag holding roller 142 have substantially the same diameter.
The axis of the shaving roller 142 is located on the upstream side in the transport direction of the continuous label paper 30 in the horizontal direction with respect to the vertical plane connecting the axis of the release roller 147 and the axis of the shaving winding shaft 51. At the same time, the axis of the residue holding roller 142 is located on the axis side of the residue winding shaft 51 in the vertical direction with respect to the axis of the release roller 147.

At the other end of the swinging portion 150, one end 153a of the slag holding air cylinder 153 is rotatably attached (swingable).
The other end 153b of the debris holding air cylinder 153 is located below the axis of the peeling roller 147 in the vertical direction and at a position separated from the axis of the peeling roller 147 from one end 153a of the debris holding air cylinder 153 in the horizontal direction. It is rotatably fixed.

The slag holding air cylinder 153 is connected to an air regulator (not shown), and by controlling the supply of driving air, the other end side of the swing portion 150 can be pressed with a constant pressing force. The slag holding air cylinder 153 is capable of pressing the slag holding air cylinder 153 toward the slag take-up shaft 51 in response to the swing of the swing portion 150 by supplying air so as to extend by the air regulator. ing. As a result, the slag holding air cylinder 153 swings the slag holding roller 142 toward the center of 147b in the direction of contact with the slag roll 37, and at this time, adjusts the contact pressure between the slag holding roller 142 and the slag roll 37. be able to.
The application of the pressing force to the slag holding roller 142 toward the slag roll 37 is not limited to the air cylinder, and may be a pressure spring, an electric cylinder, or the like.

The slag holding air cylinder 153, the swinging portion 150, the slag holding roller 142, and the guide belt 145 constitute the slag holding and conveying section 200.
Even when the slag holding roller 142 is pressed by the slag holding air cylinder 153 and the roll diameter D of the slag roll 37 changes (increases), the slag holding roller 142 always comes into contact with the outer peripheral surface 36a of the slag roll 37 at a constant pressure. The scrap roll 37 rotates at the same speed as the winding speed.

Guide grooves 147f and 142f are provided around the outer peripheral surface 147a of the peeling roller 147 and the outer peripheral surface 142a of the residue holding roller 142 in the circumferential direction.
The same number of guide grooves 147f and 142f are provided as positions that coincide with each other in the axial direction of the peeling roller 147 and the slag holding roller 142.
The guide grooves 147f and 142f are U-shaped grooves or V-shaped grooves, and are provided at least at two locations in the axial direction of the peeling roller 147 and the slag holding roller 142.

An endless guide belt (round belt) 145 is wound around the guide grooves 147f and 142f, respectively, and the position of the guide belt (round belt) 145 in the belt width direction is determined.
The depths of the guide grooves 147f and 142f are set to be equal to or slightly larger than the cross-sectional outer diameter of the guide belts (round belts) 145, and the guide belts (round belts) 145 from the guide grooves 147f and 142f have outer peripheral surfaces 147a and 142a, respectively. The depth is set so that it does not protrude outward from the belt.

The plurality of guide belts (round belts) 145 wound around the outer peripheral surface 147a of the peeling roller 147 and the outer peripheral surface 142a of the shaving roller 142 are parallel to each other and substantially coincide with the transport direction of the shavings 36. Move to.
The plurality of guide belts (round belts) 145 are arranged in the width direction of the punched shavings 36, which is the axial direction of the peeling roller 147, and all form a plane parallel to the transport direction of the shavings 36. At least two guide belts (round belts) 145 may be provided in the width direction of the scrap 36 which is the axial direction of the release roller 147, but in order to stably convey the scrap 36, a plurality of guide belts (round belts) 145 may be provided. It is preferable that the slags 36 are provided at substantially equal intervals in the width direction of the slags 36.

As a result, the slag 36 to be conveyed is uniformly contacted with the outer peripheral surface 147a of the peeling roller 147 and the outer peripheral surface 142a of the slag holding roller 142 and guided.
As the guide belt (round belt) 145, for example, a van cord manufactured by Bando Chemical Industries, Ltd. can be applied.
The guide belt 145 is not limited to the round belt, but may be a flat belt, a V belt, or the like. At this time, it is preferable that the guide grooves 147f and 142f also have a cross-sectional shape corresponding to the adopted guide belt. Further, the guide belt 145 may be guided as long as it can prevent deformation of the slag 36 itself with respect to the entire width of the slag 36 and can guide the guide belt 145, and its arrangement is not limited to the illustrated example of the present embodiment. Further, as long as the guide belt 145 is divided in the axial direction of the release roller 147 and the residue holding roller 142, the width dimension (cross-sectional dimension) and the number thereof are not limited.

Further, the guide belt (round belt) 145 is wound between the release roller 147 and the release roller 142, and rotates between the release roller 142 and the release roller 147 by contact with the release roller 142. do. At the same time, since the guide belt (round belt) 145 is wound between the peeling roller 147 and the shaving roller 142, the peeling roller 147 and the shaving roller 142 can rotate at the same speed.
As a result, the peeling roller 147 is at the same speed as the rotation of the shaving roller 142, which is in contact with the outer peripheral surface 36a of the shaving roll 37 and has a rotation speed corresponding to the winding speed of the shaving roll 37. Can be rotated.

Therefore, the winding speed of the scraping roll 37 and the scraping speed of the peeling roller 147 can be synchronized.
Since the guide belt (round belt) 145 is wound around the slag holding roller 142 near the contact with the outer peripheral surface 36a of the slag roll 37, it is guided by a plurality of round belts and is guided from the release roller 147 to the slag holding roller 142. The slag 36 that has been conveyed up to is wound around the slag take-up shaft 51 while the outer peripheral surface 36a of the slag roll 37 is suppressed from becoming uneven.

In the above configuration, the rotation drive source such as a motor is not connected to the peeling roller 147 and the residue holding roller 142. The slag holding roller 142 rotates by coming into contact with the outer peripheral surface 36a of the slag roll 37 that is rotationally driven. The peeling roller 147 is rotationally driven by a guide belt (round belt) 145 wound around a rotating residue holding roller 142. A rotation drive source such as a motor may be connected to the peeling roller 147 and the residue holding roller 142 to drive the stripping roller 147.

The scrap 36 peeled from the mount 31 is wound about half a circumference of the outer peripheral surface 147a of the peeling roller 147. After that, the slag 36 is formed by a transfer guide conveyor formed by a plurality of guide belts (round belts) 145 in the transfer path from the release roller 147 to the slag take-up shaft 51 at the upper position. You will be guided to maintain. The slag 36 is guided by a transport path and is transported to the slag take-up shaft 51 without causing slack or twisting.

The lees holding roller 142 provided at a position downstream of the transport guide conveyor can swivel around the roller center 147b, which is the support shaft of the peeling roller 147, as a fulcrum. The slag holding roller 142 always contacts and rotates with a constant pressure on the outer peripheral surface 36a of the slag roll 37 due to the pressing force of the slag holding air cylinder 153, and the unevenness of the outer peripheral surface 36a of the slag roll 37 is evened out to form a shape. It has the effect of adjusting the pressure. As a result, the tension fluctuation due to the unevenness of the outer peripheral surface 36a of the slag roll 37 is reduced, and the vibration due to the eccentric rotation of the slag roll 37 is also reduced, so that the slag 36 can be wound without being cut.

Since the pressing force of the slag holding air cylinder 153 can be adjusted by adjusting the pressure setting of the air regulator, it can be increased or decreased according to the unevenness of the outer peripheral surface 36a of the slag roll 37.

The slag holding roller 142 can adjust the air pressure by the slag holding air cylinder 153 with a regulator provided in the air piping path. For example, the air pressure of the regulator is adjusted to 0.05 to 0.3 MPa, and the contact pressure of the waste presser roller 142 is arbitrarily adjusted according to the conditions such as the type of continuous label paper 30 (see FIG. 4) and the extraction area. It is configured to be changeable to.

That is, the slag holding roller 142 is adjusted so as to come into contact with the outer peripheral surface 36a of the slag roll 37 at a pressure that does not cause vibration. By applying pressure to the outer peripheral surface 36a of the slag roll 37 so as not to generate vibration, the slag 36 being wound may collapse on the slag take-up shaft 51, and air may be introduced between the layers of the slag 36 to be wound. It is possible to prevent excessive entrainment. That is, the roll shape of the slag roll 37 can be suitably corrected by the slag holding roller 142.
By correcting (correcting) the roll shape of the slag roll 37 with the slag holding roller 142, the unevenness of the outer peripheral surface 36a of the slag roll 37 can be made uniform to some extent. As a result, fluctuations in tension due to the unevenness of the outer peripheral surface 36a of the slag roll 37 can be suppressed to some extent.

In this way, the slag holding roller 142 is made to correspond to the change in the roll diameter D of the slag roll 37, and the slag holding roller 142 can be brought into contact with the outer peripheral surface 36a of the slag roll 37. Therefore, the entire area of the outer peripheral surface 36a of the slag roll 37 can be flattened by the slag holding roller 142. As a result, the outer peripheral surface 36a of the scraping roll 37 and the outer peripheral surface 147a of the peeling roller 147 do not come into contact with each other at the distance r between the outer peripheral surface 36a of the scraping roll 37 and the outer peripheral surface 147a of the peeling roller 147. The slag holding roller 142 can be suitably maintained in a state of being in contact with the outer peripheral surface 36a of the slag roll 37. Therefore, the tension generated in the slag 36 during winding on the slag take-up shaft 51 can be satisfactorily stabilized.

The roller center 147b of the peeling roller 147 is in the direction of connecting the axis of the peeling roller 147 and the axis of the waste winding shaft 51 with respect to the axial center position of the waste winding shaft 51 by the peeling roller position adjusting unit 220. The position can be set in the direction orthogonal to the direction, that is, in the horizontal direction.
A pair of peeling roller position adjusting portions 220 are provided at both end positions of the peeling roller 147, and each of them can independently set the horizontal position of the peeling roller 147.

As shown in FIGS. 3, 4, and 5, the peeling roller position adjusting portion 220 is located inside the support groove portion 221 provided on the frame 12 and supporting the end portion of the peeling roller 147 and the support groove portion 221. It has a screw portion 222 extending in parallel with the support groove portion 221 and an adjusting handle 224 connected to the screw 222 via the shaft 223 of the arm.
In FIG. 4, the peeling roller position adjusting unit 220 is partially omitted.

The support groove portion 221 is provided in the support portion 12a provided on the release roller 147 side integrally with the frame 12. The support groove portion 221 has a straight line portion upper surface 221a extending in a substantially horizontal direction on a straight line and having a substantially flat surface, and a straight line portion lower surface 221b parallel to the straight line portion upper surface 221a. The end of the peeling roller support shaft 147k that rotatably supports the peeling roller-147 with the roller center 147b as the center of rotation is located in the support groove portion 221 via a ball bearing 147m.
The peeling roller support shaft 147k is supported by the support groove portion 221 so as to be slidable in the horizontal direction with respect to the support portion 12a and the frame 12. In the vicinity of the end portion of the peeling roller support shaft 147k, the portions at the upper and lower positions thereof are flattened to form a flattening surface 147n. Both the flat surface 147n are in contact with the straight portion upper surface 221a and the straight portion lower surface 221b of the support groove portion 221.
The threaded portion 222 extends in the horizontal direction orthogonal to the axis of the peeling roller 147 and is screwed so as to penetrate the end portion of the peeling roller support shaft 147k. By rotating the threaded portion 222, the end portion of the peeling roller support shaft 147k can be moved along the support groove portion 221 in the extending direction of the threaded portion 222.

A position restricting portion 227 is provided at one end of the shaft 223 of the arm to regulate the horizontal position of the threaded portion 222, and then the threaded portion 222 is formed in a coaxial state. An adjustment handle 224 is connected to the other end of the arm shaft 223. When the adjustment handle 224 is rotated, the threaded portion 222 is rotated via the shaft 223 of the arm, and the end portion of the peeling roller support shaft 147k is oriented in the horizontal direction orthogonal to the axis of the peeling roller 147 according to the rotation of the threaded portion 222. It becomes possible to move.
A movement amount indicator 226 is provided at the other end of the arm shaft 223. The movement amount display 226 can detect the rotation speed of the shaft 223 of the arm and display the movement amount of the end portion of the peeling roller support shaft 147k, that is, the movement amount of the roller center 147b of the peeling roller 147. ..

As shown in FIGS. 3 to 6, the peeling roller position adjusting unit 220 makes it possible to adjust the relative position between the peeling roller 147 provided close to the flow direction and the label transfer blade 144 by the adjusting handle 224. There is.
By rotating the adjustment handle 224 of the peeling roller position adjusting unit 220, the peeling roller 147 can be horizontally moved as shown by the right side position shown by the solid line in FIG. 6 and the left side position shown by the broken line in FIG. At this time, the peeling roller 147 can move horizontally while maintaining a predetermined gap in which the bottom surface 147 g, which is the lowermost end of the outer peripheral surface 147a, does not urge the continuous label paper 30 to the label transfer blade 144 side.

Here, when the peeling roller is located at the left side position shown by the broken line in FIG. 6, the scrap 36 of the continuous label paper 30 is peeled off from the mount (peeling sheet) 31, and the label 34 is attached to the mount (peeling sheet) 31. While still attached, head toward the label transfer roller 45 side.
However, if the debris 36 of the deformed label, that is, the complicated and relatively large debris 36, does not allow the debris 36 to be peeled off and lifted smoothly by the peeling roller 147, turn the adjustment handle 224. , The peeling roller 147 is advanced to the right position shown by the solid line in FIG.

At the right position shown by the solid line in FIG. 6, the scrap 36 and the label 34 of the continuous label paper 30 are separated from the mount (release sheet) 31 by the label transfer blade 144 and then head toward the release roller 147. Therefore, at the right position shown by the solid line in FIG. 6, the scraps are wound while being peeled off from the mount (release sheet) 31, and the scraps are wound more smoothly than at the left position shown by the broken line in FIG.

At this time, the label 34 exiting the release roller 147 has a top-bottom position with respect to the mount (release sheet) 31 which is wound around the label transfer roller 45 and conveyed from the label transfer blade 144 via the conversion roller 44. It is reattached in a shifted state and transported to the downstream side. Further, since the scraping 36 is endlessly connected, it is directed toward the peeling roller 147 side by the winding force of the upper guide belt (round belt) 145, the milling roller 142, and the scrap winding shaft 51, and is indicated by an arrow in FIG. It is pulled upward by the rising tension of the peeling roller 147 indicated by F1.

On the other hand, on the label 34, a force that causes the mount (release sheet) 31 to flow downward at the tip of the label transfer blade 144 acts as shown by an arrow F2 in FIG. 6 and moves in the direction of the label transfer roller 45. Therefore, it is not rolled up together with the scrap 36.

The relative position between the peeling roller 147 and the label transfer blade 144 for the peeling roller 147 to smoothly peel and lift the shavings 36 changes depending on the shape of the shavings 36. The relative position is adjusted with the adjustment handle 224. Further, when the peeling roller 147 is moved in the front-rear direction, it is necessary to set the distance r between the outer peripheral surface 36a of the above-mentioned scraping roll 37 and the outer peripheral surface 147a of the peeling roller 147 in relation to the rocking portion 150. Change accordingly.

As shown in FIGS. 7 and 9, the detection means 20 includes a first sensor 116, a second sensor 117, a third sensor (second detection unit) 118, and a line encoder (first detection unit) 119 (FIG. 7). 3, see FIG. 11).
The first sensor 116 is attached to the upper portion 12b of the frame 12 via the first mounting bracket 127. The first sensor 116 detects the detection piece 128. The detection piece 128 is attached to the end portion 85c of the side surface 85b of the first table 85. By detecting the detection piece 128, the first sensor 116 determines the upper limit of the first table 85 (that is, the moving body 76) that moves in the vertical direction.
The second sensor 117 is attached to a portion 12c closer to the lower portion than the upper portion 12b of the frame 12 via the second mounting bracket 129. The second sensor 117 detects the detection piece 128. The second sensor 117 detects the detection piece 128 to determine the lower limit of the first table 85 (that is, the moving body 76) that moves in the vertical direction.

Here, the mounting position and detection position of the first sensor 116 and the second sensor 117, and the number of the first sensor 116 and the second sensor 117 are not limited to the embodiments. For example, the first sensor 116 and the second sensor 117 may be attached from the front side of the first table 85. Further, an elongated hole may be provided on the front surface of the slider 84 with a length of the maximum movement amount + α, and one sensor may be provided on the front side of the slider 84. Further, the side surface 85b of the first table 85 may be scraped off stepwise in the upper and lower end directions, the convex state may be set to the movement amount + α, and the determination may be made by a sensor provided at one place.

The third sensor 118 is attached to the bracket 121 on the output shaft side of the powder clutch 53. Specifically, the plate 122 is attached to the output shaft side of the powder clutch 53. One end 121a of the bracket 121 is attached to the lower end of the plate 122. The third sensor 118 is attached to the other end 121b of the bracket 121. Further, the rotating body 132 is coaxially provided on the fourth timing pulley 69 of the output shaft of the powder clutch 53, and the detection piece 133 is provided on the outer periphery of the rotating body 132.
Here, the fourth timing pulley 69 of the output shaft of the powder clutch 53 and the first timing pulley 58 of the lees winding shaft 51 are formed to have the same number of teeth. That is, the rotation speed of the rotating body 132 (that is, the detection piece 133) is the same as the rotation speed of the lees winding shaft 51. Therefore, one rotation of the lees winding shaft 51 is detected by detecting the detection piece 133 with the third sensor 118.
Hereinafter, the pulse signal indicating the rotation speed of the lees winding shaft 51 is referred to as a “winding pulse”.

Here, the mounting positions of the third sensor 118 and the detection piece 133 are not limited to the example of the present embodiment. Other mounting positions may be, for example, the same rotation points as the lees winding shaft 51 on the driving side of the frame 12. The mounting position may be such that a pulse is transmitted once from the third sensor 118 each time the lees winding shaft 51 makes one rotation.

As shown in FIGS. 1 to 3 and 11, the transport path of the continuous label paper 30 includes a third servomotor (not shown) for transporting the continuous label paper 30, a transport roller 41, and a nip roller (or , Nip roller) 42, guide roller 43, conversion roller 44, label transfer roller 45, re-crimp receiving roller 46, and re-crimping roller 47. A line encoder 119 is provided along with the third servomotor. In FIG. 11, the label transfer blade 144, the conversion roller 44, the label transfer roller 45, the re-crimp receiving roller 46, and the re-crimp roller 47 are not shown.

The line encoder 119 is a rotary encoder connected in the transport path (specifically, the transport roller 41) of the continuous label paper 30. The line encoder 119 transmits a pulse signal corresponding to the amount of continuous label paper 30 conveyed. That is, the line encoder 119 detects the amount of continuous label paper 30 conveyed. Hereinafter, the pulse signal corresponding to the transport amount is referred to as a “transport pulse”.
Here, the roll diameter D of the waste roll 37 is calculated from the transfer amount of the continuous label paper 30 by detecting the transfer pulse of the line encoder 119 with respect to the take-up pulse when the lees take-up shaft 51 makes one rotation. Can be found at.
The positions of the transfer roller 41, the nip roller (or nip roller) 42, the guide roller 43, the conversion roller 44, the label transfer roller 45, the re-crimp receiving roller 46, the re-crimping roller 47, and the line encoder 119 are at the positions shown in the figure. Not limited.

The roll diameter D of the scrap roll 37 is obtained by the calculation unit 22 based on the winding pulse and the carrier pulse amount. That is, the calculation unit 22 obtains the roll diameter D of the waste roll 37 from the amount of the carrier pulse of the line encoder 119 with respect to the winding pulse transmitted from the third sensor 118 each time the waste winding shaft 51 makes one rotation. Can be done.

Next, a method of obtaining the roll diameter D of the slag roll 37 by the calculation unit 22 will be described with reference to FIG.
As shown in FIG. 11, the roll diameter of the residue roll 37 is D, and the feed amount of the continuous label paper 30 when the residue winding shaft 51 makes one rotation (that is, the circumference of the wound residue 36). If it is L,
D = L / π ... (1)
Will be.
On the other hand, a first transport roller 41 having a roll diameter d and a line encoder 119 are provided in the transport path of the continuous label paper 30.

Let n be the number of transfer pulses transmitted by the line encoder 119 for each rotation of the first transfer roller 41. When the continuous label paper 30 is conveyed by a distance πd, n-pulses are transmitted from the line encoder 119. Therefore, the feed amount of the continuous label paper 30 per one carrier pulse transmitted by the line encoder 119 is πd / n.

Here, it is assumed that the number of transmitted pulses of the carrier pulse of the line encoder 119 when the _lees winding shaft 51 makes one rotation is no.
L = πdn _o / n ... (2)
Will be.
By substituting equation (2) into equation (1),
D = dn _o / n ... (3)
Is obtained.
The roll diameter d and the number of conveyed pulses n of the line encoder 119 are known values. As a result, the roll diameter D of the scrap roll 37 can be obtained from the number of conveyed _pulses no transmitted by the line encoder 119.

Next, an example of raising the lees winding shaft 51 by the control unit 24 will be described with reference to FIGS. 4, 12, and 13.
As shown in FIG. 4, the peeled residue 36 is in a vacant state with the label 34 removed. Therefore, when the lees are wound around the lees winding shaft 51, if the tension applied to the lees 36 is changed, the lees are easily cut. Here, the label 34 is not limited to a simple contour shape such as a single quadrangle or a circle. In particular, as shown in FIG. 4, in the case where the predetermined shape of the label 34 has an irregular shape having a complicated contour, when the tension of the slag 36 fluctuates, the slag 36 becomes easy to cut. The contour shape of the label 34 shown in FIG. 4 will be described as, as an example, a shape in which the length is not uniform in the width direction and the transport direction of the continuous label paper 30 in order to facilitate understanding of the configuration.

For example, when the slag path of the label 34 is long, the amount of shrinkage in the width direction of the slag 36 is large and the load is concentrated, or the roll diameter of the slag roll 37 is large and the slag 36 is removed. It becomes easy to cut at the place where the tension applied to the is high.
Here, the slag path means a section from the slag 36 being peeled from the mount 31 by the peeling roller 147 to reaching the slag take-up shaft 51, and in this section, the slag winding from the peeling roller 147. It means that the scrap 36 is conveyed to the shaft 51 without support.

On the other hand, it is conceivable that the outer peripheral surface 36a of the slag roll 37 is kept in a state of being in pressure contact with the outer peripheral surface 142a of the slag holding roller 142.
In this state, it is conceivable that a difference in roll diameter D occurs at any of the outer peripheral surfaces 36a of the slag roll 37 due to uneven winding such as the uneven shape of the outer peripheral surface 36a of the slag roll 37. .. Further, it is conceivable that the slag 36 may be wavy, twisted or otherwise deformed in the slag path, so that the slag roll 37 may be eccentrically wound with respect to the paper tube 64 or vibration may occur. .. Therefore, the tension applied to the shavings 36 may fluctuate and the shavings 36 may be cut.

From the above, it is preferable that the position of the slag take-up shaft 51 is such that the slag path, that is, the section where the slag 36 is not supported is always a short distance, and the winding unevenness does not occur. Therefore, in the slag take-up device 10 of the present embodiment, the outer peripheral surface 36a of the slag roll 37 does not corrode with the outer peripheral surface 147a of the peeling roller 147, and the slag holding roller 142 is the outer circumference of the slag roll 37. The position of the dregs take-up shaft 51 is determined at a position that is an interval (distance) r (see FIGS. 8, 10, 11, and 12) in a state of being in contact with the surface 36a. Further, the position of the slag take-up shaft 51 is determined so that the outer peripheral surface 36a of the slag roll 37 and the outer peripheral surface 142a of the slag holding roller 142 are in pressure contact with each other.

Here, by applying tension to the shavings 36, the shavings 36 contract in the width direction. For example, as shown in FIG. 4, when the slag 36 is pulled out in an irregular shape, the slag 36 has a transport direction band-shaped portion 361 which is a continuous portion in the transport direction and a continuous portion in the width direction. A band-shaped portion 362 in the width direction is formed.
The transport-direction strip-shaped portion 361 of the slag 36 is wound around the slag take-up shaft 51 in a state of being stretched in the transport direction by tension and contracted in the width direction. In this case, tension does not act on the widthwise band-shaped portion 362 of the grid-shaped scraps 36, and the strips 362 are loosened and floated with respect to the transport-direction strips 361. It may be wound around the take shaft 51.

Therefore, the roll diameter D (see FIG. 11) of the widthwise strip-shaped portion 362 of the pomace roll 37 is larger than the roll diameter D of the transport-direction strip-shaped portion 361. Therefore, a slag holding roller 142 (see FIG. 4) is provided so that the roll diameter D of the width direction strip 362 of the slag roll 37 and the roll diameter D of the transport direction strip 361 of the slag roll 37 are the same. ing.
At the same time, in order to eliminate the slag path, that is, the section where the slag 36 is not supported, a plurality of guide belts extending in the transport direction in the section from the peeling roller 147 to the outer peripheral surface 36a of the slag roll 37 ( The round belt) 145 supports the scrap 36.

At the time of winding, the scrap 36 separated from the continuous label paper 30 on the downstream side of the peeling roller 147 is wound around the peeling roller 147 for about half a turn and then transported to the upper scrap winding shaft 51. .. In the transport path from the peeling roller 147 to the outer peripheral surface 36a of the scrap roll 37, the transport guide conveyor is configured by a plurality of guide belts (round belts) 145 separated in the width direction and stretched in the transport direction. ing. The pomace 36 is spread and guided on a transport guide conveyor. Since the slag 36 is guided and supported by this transport path, it can be regarded as not a slag path. Therefore, the slag 36 can be stably lifted without twisting, inversion, or the like.

In this transfer guide conveyor, the length of the guide belt (round belt) 145 in the transfer direction, that is, the distance in the transfer direction of the transfer path is raised by the outer peripheral surface 64a of the paper tube 64 shown in FIG. 12 (A). At the initial position where the work is performed, the scrap 36 is set to be equal to or larger than the minimum span LC (see FIG. 12) required to maintain a straight shape. The span LC is set to 74 mm as an example. The length of the guide belt (round belt) 145 is defined by the length of the swinging portion 150, that is, the distance LD between the shafts of the peeling roller 147 and the shaving roller 142.

As shown in FIGS. 3 to 5, the waste holding roller 142 located on the downstream side of the transport guide conveyor rotates the above-mentioned interaxis distance LD (see FIG. 3) around the axis of the peeling roller 147 upstream of the transport guide conveyor. It can be turned as a radius. Further, the slag holding roller 142 is pressed toward the outer peripheral surface 36a of the slag removing roll 37 by the slag holding air cylinder 153. As a result, even if the roll diameter D of the slag roll 37 increases, the outer peripheral surface 142a of the slag holding roller 142 always contacts the outer peripheral surface 36a of the slag roll 37 at a constant pressure, and the slag roll 37 is wound up. The speed and the outer peripheral surface 142a of the residue holding roller 142 rotate at the same circumferential speed.

A guide belt (round belt) 145 is wound between the shaving roller 142 and the peeling roller 147, and the shaving roller 142 and the peeling roller 147 that rotate by contact with the shaving roll 37 have the same speed. Rotate with. Therefore, the winding speed on the outer peripheral surface 36a of the scraping roll 37, the circumferential speed of the outer peripheral surface 142a of the cake holding roller 142, and the circumferential speed of the outer peripheral surface 147a of the peeling roller 147 are all the same.
As a result, after being separated by the peeling roller 147, the peeling roller 147 and the slag holding roller 142 support the slag 36 from the outer peripheral surface 36a of the slag roll 37 at the same speed as the winding speed of the slag roll 37. do.

On the outer peripheral surface 147a of the peeling roller 147, the guide belt (round belt) 145 is wound so as not to protrude from the guide groove 147f. As a result, the scrap 36 is uniformly contacted with the outer peripheral surface 147a of the peeling roller 147 and guided.
The scrap 36 is lifted in contact with the outer peripheral surface 147a of the release roller 147, and then guided along the guide belt (round belt) 145 while being supported by the guide belt (round belt) 145. The guide belt 145 circulates slower than the winding speed of the slag roll 37 by the amount submerged in the guide groove 147f to guide the slag 36.

Similarly, on the outer peripheral surface 142a of the slag holding roller 142, the guide belt (round belt) 145 is wound so as not to protrude from the guide groove 142f. As a result, the slag 36 is uniformly contacted with the outer peripheral surface 142a of the slag holding roller 142 and guided.
The slag 36 guided along the guide belt (round belt) 145 is placed on the outer peripheral surface 36a of the slag roll (paper tube) 37 at the contact position between the slag holding roller 142 and the outer peripheral surface 36a of the slag roll 37. It wraps around smoothly along with it.
The guide belt (round belt) 145 pulls out the slag 36 so as to be in contact with the outer peripheral surface 36a of the slag roll 37 in the inlet nip N section of the guide belt inlet of the outer peripheral surface 142a of the slag holding roller 142 shown in FIGS. 1 and 2. Guide.

Further, the guide belt (round belt) 145 is made of an elastic material. Therefore, the guide belt (round belt) 145 is fastly fed at the winding speed of the lees roll 37 in the inlet nip N section of the outer peripheral surface 142a of the lees holding roller 142, and is originally sent near the most downstream of N where the nip disappears. Returning to the slow lap speed, the guide belt (round belt) 145 sent extra in the N section floats up. Therefore, the guide belt (round belt) 145 protrudes from the guide groove 142f on the outer peripheral surface 142a of the slag holding roller 142 on the downstream side from the portion separated from the outer peripheral surface 36a of the slag roll 37.
In other words, in FIG. 1, the slag holding roller 142 rotates at the same speed as the slag roll 37, but the guide belt 145 orbits slower than the winding speed of the slag roll 37 by the amount submerged in the guide groove. .. At this time, in the inlet nip N section of the slag holding roller 142, the guide belt is fed at the same speed as the slag roll 37, so that the nip is lifted near the most downstream part of N. As a result, the guide belt 145 protrudes from the guide groove 142f as shown in FIG.
As a result, even in the portion where the outer peripheral surface 36a of the slag roll 37 is concave with respect to the outer peripheral surface 142a of the slag holding roller 142 which is cylindrical, the slag 36 is removed to the outer peripheral surface 36a side of the slag roll 37. Can be pressed to. Therefore, the slag 36 can be stably wound and attached to the outer peripheral surface 36a of the slag roll 37 having irregularities.

In this way, the slag 36 guided by the guide belt (round belt) 145 and stably conveyed is wound around the slag take-up shaft 51 while the outer peripheral surface 36a of the slag roll 37 is suppressed from becoming uneven. Be done.

As shown in FIG. 12, the distance r between the outer peripheral surface 36a of the scrap roll 37 and the outer peripheral surface 147a of the peeling roller 147 is usually set to be about 30 mm. However, depending on the diameter and position settings of the span LC, the slag roll 37, the peeling roller 147, and the slag holding roller 142, the setting of the interval r may be changed so that the interval r is within the range of 20 to 50 mm. Is also possible. The initial position of the lees winding shaft 51 is the position shown in FIG. 12 (A). The initial position of the slag take-up shaft 51 refers to the position of the slag take-up shaft 51 in a state where the slag 36 of the label 34 is not wound on the paper tube 64 fixed to the slag take-up shaft 51.

Returning to FIG. 4, the outer peripheral surface 64a of the paper tube 64 fixed to the slag take-up shaft 51 does not corrode with the outer peripheral surface 147a of the peeling roller 147, and the slag holding roller 142 removes the outer circumference of the slag roll 37. The interval r (see FIGS. 8, 10, 11, and 12) is set so as to be in contact with the surface 36a. Therefore, when the scrap 36 is peeled from the mount 31 by the peeling roller 147, it is guided by the guide belt (round belt) 145 and wound on the paper tube 64 fixed to the cake winding shaft 51. The wound slag 36 is integrated with the slag winding shaft 51 (that is, the paper tube 64) by the adhesive surface of the slag 36.
As a result, there is no slag path for the slag 36 to be transported by itself, and the slag 36 is wound without being cut.

Hereinafter, a method for winding the scraps of continuous label paper having no meal path to which the scraps 36 are transported by itself will be described with reference to FIG. In addition, in FIG. 12, the slag holding roller 142 is not shown.
As shown in FIGS. 3 and 12A, first, the shaft position P of the lees winding shaft 51 is set in a state where the outer peripheral surface 64a and the outer peripheral surface 147a of the paper tube 64 are separated from each other so as not to corrode. ..
Specifically, when the slag holding roller 142 diameter and the peeling roller 147 diameter are φ60 mm, the span LC is 74 mm, and the slag roll 37 diameter from φ100 mm to φ600 mm is used for winding, the interval r is usually set to about 30 mm. ing. The shaft position P indicates the distance between the outer peripheral surface 147a of the peeling roller 147 and the center 51a of the lees winding shaft 51.

As shown in FIGS. 3 and 12B, when the continuous label paper 30 is started to be conveyed, the residue winding shaft 51 rotates in the residue winding step. As the slag take-up shaft 51 rotates, the slag 36 peeled off from the mount 31 (see FIG. 4) is taken up by the paper tube 64 of the slag take-up shaft 51.
In the roll diameter calculation step, the roll diameter D of the scrap roll 37 is obtained based on the take-up pulse signal from the third sensor 118 (see FIG. 1) and the carrier pulse signal from the line encoder 119. The third sensor 118 detects one rotation of the lees winding shaft 51. The line encoder 119 detects the amount of continuous label paper 30 conveyed.
Next, the calculated roll diameter D is stored in the calculation unit 22 in the controller 21. The roll diameter obtained by adding an arbitrarily set increase in the radial dimension to the roll diameter D stored in the calculation unit 22 is set as the “rising start roll diameter D1” of the scrap roll 37 in advance.

As shown in FIGS. 3 and 12 (C), during the transfer of the continuous label paper 30, the roll of the residue roll 37 is extracted from the transfer pulse amount of the line encoder 119 cut out every time the residue take-up shaft 51 makes one rotation. The diameter D is calculated and obtained every time.
In the process of moving the slag take-up shaft, the roll diameter D of the obtained slag roll 37 is compared with the "rising start roll diameter D1". When the compared roll diameter D is larger than the "rising start roll diameter D1", the second servomotor 82 (see FIG. 1) of the vertical movement mechanism 16 is driven based on the signal from the control unit 24.
By rotating the sixth timing pulley 95 with the second servomotor 82, the rotation of the sixth timing pulley is transmitted to the fifth timing pulley 93 of the rotating shaft 89 via the third timing belt 96. As the fifth timing pulley 93 rotates, the pair of drive gears 79 rotate via the rotation shaft 89.

The rotation of the pair of drive gears 79 causes the pair of driven gears 78 to rotate. The rotation of the pair of driven gears 78 causes the pair of ball screws 77 to rotate. The rotation of the pair of ball screws 77 causes the connecting bracket 92 (that is, the moving body 76) to move in the vertical direction.
The take-up mechanism 14 is attached to the first table 85 and the second table 86 of the moving body 76. By moving the moving body 76 in the vertical direction, the lees take-up shaft 51 is raised to the shaft position P by the set value for raising the lees take-up shaft 51 of the lees take-up shaft 51 arbitrarily set. That is, the lees winding shaft 51 moves in a direction away from the peeling roller 147.
As a result, as shown in FIG. 12C, the distance r between the outer peripheral surface 36a of the scraping roll 37 and the outer peripheral surface 147a of the peeling roller 147 is such that the outer peripheral surface 36a of the scraping roll 37 is the outer peripheral surface of the peeling roller 147. The distance is such that it does not touch 147a.

After the ascending operation of the slag take-up shaft 51 is completed, the roll diameter D of the slag roll 37 is calculated again by the same method. By overwriting the roll diameter D on the calculation unit 22, a new “rising start roll diameter D1” of the lees winding shaft 51 is determined. Hereinafter, similarly, the lees winding shaft 51 is raised based on the signal from the control unit 24.

That is, the control unit 24 controls the vertical movement mechanism 16 so as to move the lees winding shaft 51 in the direction away from the peeling roller 147 or in the direction approaching the peeling roller 147 based on the roll diameter D obtained by the calculation unit 22. do.
Next, an example of moving the lees winding shaft 51 in the control unit 24 in the direction away from the peeling roller 147 will be described in detail with reference to FIGS. 12 and 13.

FIG. 12 is a front view showing the positional relationship between the slag take-up shaft 51, the slag roll 37, and the peeling roller 147 at the time points of RA, RB, and RC in FIG. FIG. 13 is a graph showing an example of the ascending timing of the lees winding shaft 51 when the lees winding operation is executed.
In FIG. 12, the interval r indicates the distance between the outer peripheral surface 36a of the scraping roll 37 and the outer peripheral surface 147a of the peeling roller 147, or the distance between the outer peripheral surface 64a of the paper tube 64 and the outer peripheral surface 147a of the peeling roller 147. Further, as described above, the shaft position P indicates the distance between the outer peripheral surface 147a of the peeling roller 147 and the center 51a of the lees winding shaft 51.

As shown in FIGS. 12A and 13, the pipe diameter of the paper tube 64 is formed to be smaller than the ascending start roll diameter D1 at the time of the rotation speed RA of the lees winding shaft 51. For example, the paper tube 64 is set to a tube diameter of 100 mm. Therefore, a distance r is maintained between the outer peripheral surface 64a of the paper tube 64 and the outer peripheral surface 147a of the peeling roller 147. As a result, the slag 36 is wound around the paper tube 64 of the slag take-up shaft 51 in a state where the slag take-up shaft 51 does not rise.

As shown in FIGS. 12B and 13, the slag 36 is wound around the paper tube 64 of the slag take-up shaft 51, so that the roll diameter D of the slag roll 37 becomes large. At the same time, the distance r between the outer peripheral surface 36a of the scrap roll 37 and the outer peripheral surface 147a of the peeling roller 147 becomes smaller.
When the slag take-up shaft 51 reaches the rotation speed RB, the roll diameter D of the slag roll 37 exceeds the “rising start roll diameter D1”.

The lees winding shaft 51 starts to rise. While the slag take-up shaft 51 is ascending, the slag 36 is continuously taken up by the slag take-up shaft 51. Since the slag 36 is continuously wound around the paper tube 64 of the slag take-up shaft 51, the roll diameter D of the slag roll 37 becomes large. In this state, the lees winding shaft 51 is raised. Therefore, the distance r between the outer peripheral surface 36a of the slag roll 37 and the outer peripheral surface 147a of the peeling roller 147 increases toward the preset slag take-up shaft rise set value.

As shown in the state (C) of FIG. 12 and FIG. 13, when the slag take-up shaft 51 has a rotation speed RC, the rise value of the slag take-up shaft 51 is set in advance (for example, the slag take-up shaft rise set value (for example). 5.0 mm) is reached. Therefore, the lees winding shaft 51 stops ascending. A new ascending start roll diameter D1 is obtained by adding an arbitrarily set increase in radial dimension (for example, 3.0 mm) to the roll diameter D when the lees winding shaft 51 stops ascending. It is determined as. Then, until the roll diameter D reaches the ascending start roll diameter D1, the slag take-up shaft 51 is not raised and the slag 36 is wound up.

As described above, by sequentially repeating the operations of RA to RC, the distance r between the outer peripheral surface 36a of the scrap roll 37 and the outer peripheral surface 147a of the peeling roller 147 is usually set in the range of 20 mm ≦ r ≦ 50 mm. Has been done.
Therefore, it is possible to maintain a distance such that the outer peripheral surface 36a of the scrap roll 37 does not come into contact with the outer peripheral surface 147a of the peeling roller 147. As a result, a stable winding shape of the slag 36 can be maintained without cutting the slag 36.

In this way, based on the roll diameter D of the slag roll 37, the slag take-up shaft 51 can be moved in a direction away from the peeling roller 147 or in a direction approaching the peeling roller 147. Therefore, the distance r between the outer peripheral surface 36a of the scrap roll 37 and the outer peripheral surface 147a of the peeling roller 147 can be maintained in a state where they do not come into contact with each other.
At the same time, by winding the scrap 36 peeled from the mount 31 by the peeling roller 147 in a state of being guided by the guide belt (round belt) 145, the outer peripheral surface 36a of the scrap roll 37 is wound from the outer peripheral surface 147a of the peeling roller 147. It is possible to suppress the size of the desquamation path up to.

As a result, even if the predetermined shape of the label 34 is other than a rectangle or a circle and the vertical and horizontal tensions in the scrap 36 are irregular, the tension generated in the scrap 36 during winding is increased. By stabilizing it, it is possible to prevent the scrap 36 from being cut to the maximum extent.
Further, the transport path from the outer peripheral surface 147a of the peeling roller 147 to the outer peripheral surface 36a of the slag roll 37 is guided by the guide belt (round belt) 145 to eliminate the slag path dimension, as compared with the conventional technique. Even if a strong tension is applied to the slag 36, it is possible to prevent the slag 36 from being cut.

Further, the slag holding roller 142 winds up the slag 36 while pressing the outer peripheral surface 36a of the slag roll 37, and the guide belt (round belt) 145 pulls the slag roll 37 toward the outer peripheral surface 36a. By winding the slag 36 while pressing it, the slag 36 can be stably wound and the slag 36 can be prevented from being cut to the maximum extent.
Further, by suppressing the cutting of the scrap 36, the printing speed of the continuous label paper 30 can be increased. As a result, the productivity of the label 34 can be significantly improved.

In this embodiment, the increase in the radial dimension is set to 3.0 mm and the set value for raising the lees winding shaft is set to 5.0 mm, but the increase in the radial dimension and the set value for raising the lees winding shaft are set. , 3.0 mm and 5.0 mm are not limited. That is, the slag so that the distance r between the outer peripheral surface 64a of the paper tube 64 fixed to the slag take-up shaft 51 with the lug 62 or the outer peripheral surface 36a of the slag roll 37 and the outer peripheral surface 147a of the peeling roller 147 is maintained in a certain range. The control may be such that the take-up shaft 51 is raised.
As another example, for example, the thickness dimension of the continuous label paper 30 may be measured before the start of winding, and the set value for raising the lees winding shaft may be changed according to the value. Further, the value may be changed depending on the type of the continuous label paper 30 and the winding speed.

Further, the vertical movement mechanism 16 of the lees winding shaft 51 manually moves the lees winding shaft 51 up and down while the winding operation is stopped, for example, in addition to the automatic operation during operation as described in the present embodiment. It is also possible to make it. The manual operation of the slag take-up shaft 51 is used, for example, when the slag roll 37 is removed from the slag take-up shaft 51 when the slag roll 37 reaches the maximum roll diameter.

Although the preferred embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the above embodiment. The various shapes and combinations of the constituent members shown in the above-described embodiments are examples, and various changes can be made based on design requirements and the like within a range that does not deviate from the gist of the present invention.

For example, in the above embodiment, the moving body 76 is moved in the vertical direction by a pair of linear motion guides 75 and a pair of ball screws 77, but the method of moving the moving body 76 is not limited to the above embodiment. As another example, for example, a trapezoidal screw or the like can be used instead of the pair of ball screws 77. Further, it is preferable to provide a pair of ball screws 77 and trapezoidal screws in terms of position accuracy and durability, but one may be used.

Further, in the above embodiment, the powder clutch 53 is exemplified as the tension adjusting unit, and an example in which the fluctuation of the tension applied to the slag 36 of the slag roll 37 by the powder clutch 53 is kept constant has been described, but the present invention is limited to this. do not have. As another tension adjusting unit, it is also possible to adopt another clutch or the like having a function of sliding smoothly and changing the set torque step by step.

Further, in the above embodiment, the rotary encoder has been described as an example of the line encoder 119 of the first detection unit that detects the conveyed amount of the continuous label paper 30, but the present invention is not limited to this.

Further, in the above embodiment, an example in which the slag take-up shaft 51 is moved by the control unit 24 based on the roll diameter D obtained by the calculation unit 22 has been described, but the present invention is not limited to this. As another example, for example, it is also possible to manually move the lees winding shaft 51 based on the roll diameter D obtained by the calculation unit 22.

Further, in the above embodiment, the peeling roller 147 is exemplified as the peeling roller, but the peeling roller is not limited to this. As another example, for example, the peeling roller can be a movable peeling roller.

Further, in the above embodiment, an example in which the slag take-up shaft 51 is provided on the upper side in the vertical direction with respect to the roller center 147b of the peeling roller 147 has been described, but the present invention is not limited to this.
