BACKGROUND OF THE INVENTION
The present invention relates to a compressed product package formed by compressing and packing a collection of a large number of items such as industrial waste, and a manufacturing apparatus and a manufacturing method thereof.
[0002]
[Prior art]
As a conventional apparatus for manufacturing a compressed product package, there is one disclosed in JP-A-7-164190.
[0003]
In this compressed product packaging body manufacturing apparatus, a film wrapping device is installed at a discharge port of a compressed product assembly in a compression chamber that compresses industrial waste into a predetermined shape to form a compressed product assembly, and is discharged from the discharge port. A film is wound around the compressed product assembly, and a spiral film winding layer is deposited on the compressed product assembly, thereby forming a compressed product package made of compressed industrial waste. .
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional compressed product manufacturing apparatus, when the compressed product aggregate is discharged from the discharge port of the compression chamber, the compression force on the compressed product assembly is released and the compressed product is expanded by its restoring force and the shape retention force is reduced. Therefore, when a film is wound around such a compressed product aggregate, there is a problem that a part of the compressed product is scattered and spilled or the shape of the compressed product package as the final product becomes unstable.
[0005]
The present invention has been made in order to solve the above-described problems, and is capable of preventing the scattering of the compressed material and the instability of the shape of the compressed material package, the manufacturing apparatus thereof, and the manufacturing apparatus thereof. The object is to provide a manufacturing method.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a compressed product package manufacturing apparatus according to the present invention includes a compression means for compressing a collection of a large number of items to form a compressed product assembly in a compression space, and the formed compressed product. A guide cylinder that constitutes an extrusion passage from the compression space to the outside of the assembly, an extrusion means for extruding the compressed product assembly from the tip of the guide cylinder, and a belt-shaped wrapping member that circulates around the guide cylinder Winding means, the compression space is formed in a columnar shape extending in the push-out direction, the guide tube has the same cross-sectional shape as the cross-sectional shape of the compression space, and the cross-sectional shape of the guide tube is The notch is not formed so as to cut out the outward bend in the contour. In other words, the belt-shaped packaging member that is fed out is configured so as to be wound across the compressed product aggregate pushed out from the tip of the guide tube and the guide tube. (Claim 1).
[0007]
With this configuration, the compressed product assembly moves through the guide tube by setting the rolled-out packaging member to be wound over the compressed product assembly pushed out from the tip of the guide tube and the guide tube. Therefore, the compressive force on the compressed product assembly is maintained, the expansion is prevented, and the shape holding force is maintained, while the compressed product assembly is successively wound around the sequentially extruded portion on the guide cylinder. The wound layer of the strip-shaped packaging member is applied by the mechanism described below. That is, the tension of the wound belt-shaped packaging member strongly acts on the outward bent portion in the profile of the cross-sectional shape of the article to be wound. The frictional force between the compressed product aggregate located at the notch and the belt-shaped packaging member acts strongly. Therefore, the portion of the belt-shaped packaging member wound on the guide tube is pulled by the compressed product assembly located at the notch and moves on the guide tube. It is deposited on the object assembly. Therefore, it is possible to prevent a part of the compressed product assembly from being scattered or the shape of the compressed product package as the final product from becoming unstable.
[0009]
In the above case, the cross-sectional shape may be a polygon, and the cutout may be a cutout of at least one corner of the polygon. 2 ).
[0010]
If it is set as this structure, a prismatic-shaped compressed article package can be manufactured appropriately.
[0011]
In this case, the cutout portion is constituted by a corner cutout portion that cuts out a corner portion of the polygon and a side cutout portion that cuts out a side portion of the polygon, and the corner cutout portion and the side cutout portion are formed. It is good also as what is formed in all the corners and sides of the polygon, respectively, and the side notch is shallower than the corner notch. 3 ).
[0012]
With such a configuration, the force for pulling the portion of the strip-shaped packaging member wound on the cylinder increases, while the notch portion is provided in the side portion to reduce the contact area between the guide tube and the strip-shaped packaging member. Since the frictional resistance against the movement of the part wound on the guide tube of the member is reduced, it is possible to more effectively perform the application of the part wound on the guide tube of the belt-shaped packaging member onto the compact assembly. it can. Moreover, since the side notch is formed shallower than the corner notch, the bulge of the compressed product assembly can be minimized.
[0013]
In this case, at least one of all the corner cutouts is left in the polygon so as to protrude from the back end of the corner cutout to a depth position exceeding the depth of the side cutout. It is good also as what is formed by notching the corner | angular part of (claim) 4 ).
[0014]
In the above case, the lashing member is fed from the winding means together with the belt-shaped packaging member, and the guide tube and At least one of the compacts It may be configured to be rolled up (claims) 5 ).
[0015]
With such a configuration, since a securing force can be applied by the securing member, a compressed product assembly having a restoring repulsive force can be suitably packaged.
[0016]
In this case, the winding means has a roll mounting portion on which the roll of the band-shaped packaging member and the roll of the band-shaped member processed into the lashing member are mounted, and the band-shaped drawn out from the roll of the band-shaped member The member may be processed into the lashing member, and the lashing member obtained by the processing may be fed out together with the band-shaped packaging member drawn out from the roll of the band-shaped packaging member. 6 ).
[0017]
With such a configuration, the material of the lashing member is attached to the winding means as a roll of a band-like member, so that the space factor is higher than the case where the lashing member is wound around a reel, and thus the fixation factor is increased. The mounting portion of the binding member material can be reduced in size.
[0018]
In this case, the winding means may individually apply tension to the band-shaped packaging member and the securing member. 7 ).
[0019]
With such a configuration, since the optimum tension can be applied to the belt-shaped packaging member and the lashing member having different tensile strengths, the belt-shaped packaging member and the lashing member can be fed out without causing any slack.
[0020]
In this case, the winding means may apply the tension to a securing member obtained by processing from a belt-shaped member (claims). 8 ).
[0021]
With such a configuration, tension is applied to the state of the lashing member having a higher tensile strength than that of the band-shaped member, so the cutting frequency of the material of the lashing member is higher than when tension is applied to the state of the band-shaped member. Can be reduced.
[0022]
In the above case, the push-out means may intermittently push out the compressed product aggregate from the tip of the guide tube. 9 ).
[0023]
With such a configuration, the band-shaped wrapping member is wound at a right angle to the compressed product assembly or the guide tube except for the portion wound at the moment of extrusion, so that it can be wound more strongly than when continuously extruded. Therefore, the compressed product assembly can be more suitably packaged.
[0024]
In this case, the winding means may wind the belt-shaped packaging member around the compressed product assembly and the guide tube so that the rear edge is substantially located at the back end of the notch. 10 ).
[0025]
With such a configuration, since the strip-shaped packaging member is wound so as to contact the guide tube at the back end of the notch portion, after the compressed product aggregate is pushed out, the strip-shaped packaging member is wound on it. The compressed product aggregate bulges out from the notch, and the belt-shaped packaging member is wound on the bulged compressed product aggregate. At the time of this winding, the swelled compressed product aggregate is clamped by the band-shaped packaging member and slightly compressed. At the same time as the next extrusion, the compressed product aggregate bulges in the notch, and a step is produced between the newly expanded compressed product aggregate and the compressed product assembly in which the belt-shaped packaging member is wound. And since the trailing edge of the wound belt-shaped packaging member is pushed by the newly swelled compressed product assembly so as to be hooked on the step, the portion wound on the guide tube of the belt-shaped packaging member, It can be reliably pushed out of the guide tube and deposited on the compact assembly.
[0026]
In this case, the cross-sectional shape is a polygon, and the notch is configured by a corner notch that cuts out a corner of the polygon and a side notch that cuts out a side of the polygon. The part notch part and the side notch part are respectively formed in all the corners and side parts of the polygon, and the side notch part is formed shallower than the corner notch part. For each turn of the winding means, the compressed product aggregate is pushed out by a distance corresponding to the difference between the depth of the corner cutout and the depth of the side cutout. (Claims) 11 ).
[0027]
With such a configuration, the belt-shaped packaging member having a width wider than the depth of the corner notch is wound so that the rear edge is positioned at the back end of the corner notch, so that the band-shaped packaging after the compressed product assembly is extruded. Since the rear edge of the member is located at the back end of the side cutout portion, the side cutout portion is covered with the band-like packaging member until the next time the band-like packaging member is wound. While suppressing resistance due to friction with the member, it is possible to minimize bulge of the compressed product assembly.
[0028]
In this case, at least one of all the corner cutouts is left in the polygon so as to protrude from the back end of the corner cutout to a depth position exceeding the depth of the side cutout. The winding means feeds the securing member together with the belt-shaped packaging member, and the securing means is positioned so that the securing member is positioned in the vicinity of the corner of the polygon. The binding member and the belt-shaped packaging member may be wound around the boundary between the guide tube and the compressed product assembly (claims). 12 ).
[0029]
With such a configuration, the lashing member is wound in a state of being caught in the vicinity of the corner of the polygon, and then released from the compressed product assembly, so that the guide is drawn by the strong lashing force of the lashing member. It is possible to mitigate the movement of the belt-shaped packaging member wound on the cylinder.
[0030]
Further, in the above case, when a command to replace the roll is input from the outside, the winding means is configured so that the band-shaped packaging member or the band-shaped packaging member and a portion on which the roll of the band-shaped member is mounted It is good also as what rotates so that it may be located in the predetermined position in (claim) 13 ).
[0031]
With such a configuration, by setting the predetermined position of the roll mounting portion at a position where the roll can be easily replaced, the roll mounting portion can be positioned at a position where the roll can be easily replaced only by a command input operation. The roll can be exchanged easily and safely.
[0032]
And a detection roller installed to rotate by running at least one of the band-shaped packaging member, the band-shaped member, and the securing member, and a generator connected to a rotation shaft of the detection roller. It may be provided with a packaging member cutting detection means configured to detect the presence or absence of travel of at least one of the strip-shaped packaging member, the strip-shaped member, and the lashing member based on the output of 14 ).
[0033]
With such a configuration, it is possible to detect that at least one of the belt-like member and the lashing member is not running when there is no output from the generator, so it is possible to detect the presence or absence of cutting with a simple configuration. can do.

The film F and the string-like body 12 are unwound and wound around the tip of the guide tube 33. At this time, the string-like body 12 is wound so as to be positioned inside the packaging film F. In addition, the packaging film F is wound so that a portion of about one third of the width of the wrapping film protrudes from the tip of the guide tube 33, and the protruded portion is bent inward at right angles to the peripheral surface of the guide tube. The swivel wheel 15 is rotated about one and a half times, so that the wrapping film F and the string-like body 12 are wound around the tip of the guide tube 33 about once and the edge is bent inward at a right angle. A wound layer is formed. Next, the holding of the packaging film F and the string-like body 12 by the chuck 11 is released (indicated by a two-dot chain line).
[0063]
In this state, when the compressed product aggregate S is formed as described above, the gate 4 is opened, and then the extrusion air cylinder 5 is actuated to advance the extruded plate 6 to move the compressed product aggregate S. Push out from the tip of the guide tube 33. At this time, since the compressed product assembly S moves along the guide tube 33, the compressive force on the compressed product assembly S is maintained, the expansion is prevented, and the shape retaining force is maintained. Next, as shown in FIG. 8, the swivel wheel 15 is rotated at the timing when the compressed product assembly S starts to be pushed out from the tip of the guide tube 33, and the packaging film F and the string are attached to the tip of the guide tube 33. The state body 12 is wound. Then, first, the peripheral edge portion of the front end face of the compressed product assembly S is covered with a portion bent inward of the preliminary winding layer, and then the preliminary winding layer and the portion of the compressed product assembly S that are sequentially extruded are Thereafter, the packaging film F and the wound layer of the string-like body 12 wound on the guide tube 33 are applied by the mechanism described below. That is, the tension of the wrapped packaging film F acts strongly on the corner of the guide tube 33, but the notch 34 (see FIG. 7) is formed at the corner, so that the tension causes the notch 34 to The frictional force between the positioned compressed product aggregate S and the packaging film F acts strongly. Therefore, when the portion of the packaging film F wound on the guide tube 33 is pulled by the compressed product assembly S located at the notch 34 and moves on the guide tube 33, the tip of the guide tube 33 is reached. It is removed from there and deposited on the compact assembly S. In this case, as in the conventional example, the packaging film is not wound around the compressed product aggregate that has been compressed and released and thus has a reduced shape retention force, but is compressed by being pushed out from the tip of the guide tube 33. A portion of the packaging film F that is wound on the guide tube 33 and already formed into a cylindrical shape is removed from the tip of the guide tube 33 and attached to the compressed product assembly S whose force is to be released. Therefore, it is possible to prevent a part of the compressed product aggregate from being scattered and the shape of the final product, which is a waste package, from becoming unstable.
[0064]
As described above, the wrapping film F and the string-like body 12 were sequentially wound around the distal end portion of the guide tube 33 and the compressed product assembly S pushed out from the distal end portion, and wound around the guide tube 33. The portions are sequentially deposited on the compressed product aggregate S pushed out from the tip of the guide tube 33. When the entire portion of the compressed product aggregate S is pushed into the guide tube 33, the compression plate 106 moves back to the standby position.
[0065]
Next, as shown in FIG. 9, when the extruded plate 6 advances to the most advanced position and the compressed product aggregate S is pushed out from the guide tube 33, the swivel wheel 15 stops and the extruded plate 6 moves to the standby position. Retreat and the gate 4 is closed. Thereby, the vertical winding ends. Thereby, the vertical winding layer in which the packaging film F and the string-like body 12 are spirally wound in the vertical direction is formed on the four surfaces of the compressed product aggregate S. The swivel wheel 15 stops at a position where the elevation angle (angle with respect to the horizontal direction) of the packing member supply device 108 viewed from the center of the swivel wheel 15 is about minus 45 degrees. This position is also a position designated for replacement work of the string film roll 23 and the packaging film roll 26, as will be described later.
[0066]
Next, the roller conveyor 9 on the turntable 8 is operated, and the compressed product aggregate S on which the longitudinal winding layers are formed moves onto the turntable 8. Next, the second motor 30 is actuated so that the packaging member supply device 108 rotates around the axis X and rises vertically (parallel to the rotating surface of the swivel wheel 15) (hereinafter referred to as an upright state). .
[0067]
In this state, the turning wheel 15 starts to rotate counterclockwise after rotating clockwise to a position where the elevation angle of the packing member supply device 108 is about plus 45 degrees. At the same time, the turntable 8 rotates counterclockwise in plan view. As a result, the packaging film F and the string 12 are sequentially wound around the compressed product assembly S in a spiral manner while being fed out from the packaging member supply device 108 so as to move downward from the upper end of the compressed product assembly S. It is done. Then, as shown in FIG. 10, when the packing member supply device 108 is rotated to a position where the elevation angle is about minus 45 degrees, the turning wheel 15 stops and the turntable 8 stops. During this time, the packing member supply device 108 is rotated around the axis X so that the lower end thereof is inclined backward during the winding start period and the upper end thereof is slightly inclined backward during the winding end period. This is because the packaging member supply device 108, and thus the track of the feeding roller, is not a straight line but an arc shape, so that it is prevented that one of the side edges of the packaging film F is located outside the arc track. It is to do. Further, at the time of the stop, the turntable 8 stops with the cutter 13 facing the packing member supply device 108. Next, the cutter 13 cuts the packaging film F and the string-like body 12. At this time, the chuck 11 is erected to sandwich the cut packaging film F and the end of the string-like body 12 on the packaging member supply device 108 side (not shown). Thereby, the horizontal winding was completed, and as a result, the packaging film F and the string-like body 12 were spirally wound in the horizontal direction on the remaining two surfaces of the compressed product assembly S in which the vertical winding layer was formed. A horizontal winding layer is formed. The compressed product aggregate S wound on the six surfaces with the packaging film F and the string-like body 12 is a waste packaged product Sp as a final product.
[0068]
Next, as shown in FIG. 11, the turntable 8 is rotated to the initial position, and then the roller conveyor 9 and the carry-out conveyor 10 are operated to carry out the garbage packaged product Sp, and the packing member supply device 108 is in the sideways state. As a result, the chuck 11 also falls on its side. Thereby, the operation | movement of 1 cycle of the compressed product package manufacturing apparatus 1 is complete | finished. In addition, when the string film roll 23 and the packaging film roll 26 of the packaging member supply device 108 are completed, the operator presses a predetermined operation button of the control device 104. Then, the swivel wheel 15 rotates and stops so that the packaging member supply device 108 is positioned at the position shown in FIG. This position is a position where an operator can easily replace the rolls 23 and 26. Therefore, according to the present embodiment, roll replacement can be performed easily and safely with only a button operation.
[0069]
The garbage packaged product Sp obtained as described above is covered with a wound layer in which a compressed product aggregate S formed by compressing garbage is wound so that the packaging film F and the string-like body 12 overlap each other. Therefore, the compressed product assembly S is prevented from being scattered by the wound layer of the coated packaging film F, and the compressed product assembly S having a restoring repulsive force is formed with a string-like body 12 having a high tensile strength. Since it can be secured, the compressed product aggregate S can be suitably packed.
[0070]
In the present embodiment, since the color of the packaging film F is properly used depending on the type of garbage, the type of garbage contained in the packaged product Sp can be identified simply by looking at the color of the finished garbage package Sp.
Embodiment 2
The second embodiment of the present invention exemplifies another configuration of the guide cylinder of the compression volume reduction machine and another winding method of the packaging film and the string-like body.
[0071]
12 is a perspective view showing a configuration of the guide tube according to the present embodiment, and FIG. 13 is a state in which a packaging film and a string-like body are wound around the guide tube of FIG. 12 and a compressed product aggregate pushed out from the guide tube. FIG. 4A is a right side view illustrating a state before the compressed product aggregate is extruded, and FIG. 5B is a diagram illustrating a state after the compressed product aggregate is extruded. 12 and 13, the same reference numerals as those in FIGS. 1 to 7 denote the same or corresponding parts.
[0072]
First, the configuration of the guide tube will be described.
[0073]
As shown in FIGS. 12 and 13, a corner notch 34 is formed at each of the four corners at the tip of the guide tube 33, and a rectangular side notch at the center of the four sides. 111 is formed. A depth L2 of the side notch 111 is formed shallower than a depth L1 of the corner notch 34. Further, the width of the side notch 111 is wider than the width of the protrusions 301 and 302 that are left so as to protrude relatively with the notch formed on each side. This is to reduce the frictional resistance by reducing the contact area with respect to the packaging film F wound around the side as much as possible. Of the protrusions 301 and 302 on each side, the tip of the protrusion on the vertical side (hereinafter referred to as the vertical protrusion) 301 is chamfered so as to be rounded. This is to make it easier for the string-like body 12 wound on the guide tube 33 to come off when moving on the compressed product assembly S. On the other hand, the tip of the lateral protrusion (hereinafter referred to as the lateral protrusion) 302 remains angular. And the horizontal side protrusion 302 protrudes slightly forward from the vertical side protrusion 301 (see FIG. 13). This is to apply a compressive force as far as possible to the compressed product assembly S that is about to leave the guide tube 33 to prevent its expansion and maintain its shape retaining force. In addition, the lower two corner cutouts 34 are arranged so that the vicinity of each corner (hereinafter referred to as a corner projection) 112 has a depth of the side cutout 111 from the back end of the corner cutout 34. Each corner is cut out so as to protrude to a depth position exceeding L2. That is, the corner protrusion 112 is formed in a column shape having an L-shaped cross section, and the protrusion length L4 is based on the difference L3 between the depth L1 of the corner notch 34 and the depth L2 of the side notch 111. It is a little small.
[0074]
Next, another method for winding the packaging film and the string-like body will be described.
[0075]
In FIGS. 12 and 13, the packaging film F and the string-like body 12 are wound counterclockwise unlike the first embodiment. Further, the string-like body 12 is wound so as to be positioned outside the packaging film F. The winding position of the packaging film F and the string-like body 12 on the guide tube 33 and the compressed product assembly S is determined by the winding speed of the packaging film F and the cord-like body 12 with respect to the extrusion speed of the compressed product assembly S (the rotation of the swirling ring). In this embodiment, this ratio is set so that the packaging film F is wound so that the rear edge F ′ is positioned on the back end 34a of the corner notch 34. Yes. The width Wf of the packaging film F is wider than the depth L1 of the corner notch 34, and is, for example, 500 mm. Then, the extrusion pitch Pt of the compressed product assembly S, that is, the distance at which the compressed product assembly S is extruded every time the packaging film F is wound (around the swirling ring), is expressed by the depth L1 of the corner notch 34 and the side. The distance corresponding to the difference L3 from the depth L2 of the part notch 111 is set. In this embodiment, the extrusion pitch Pt is set to 100 mm, for example. Therefore, in the present embodiment, the packaging film F is wound with a considerably large overlap amount Lp (see FIG. 13 (a)). Further, the string-like body 12 is wound so as to be positioned at the tip of the corner protrusion 112.
[0076]
According to the present embodiment configured as described above, as shown in FIG. 13A, the packaging film F is wound so as to be in contact with the guide tube 33 at the back end 34 a of the corner notch 34. Therefore, after the compressed product aggregate S is pushed out and before the packaging film F is wound on the compressed product aggregate S, the compressed product aggregate S ′ bulges from the corner notch 34 (see FIG. 13B), The packaging film F is wound on the swelled compressed product aggregate S ′. During this winding, the swelled compressed product aggregate S ′ is clamped by the packaging film F and compressed slightly (see FIG. 13B). Then, as shown in FIG. 13 (b), simultaneously with the next extrusion, the compressed product aggregate S 'bulges in the corner notch 34. The newly bulged compressed product aggregate S' and the packaging film A step 303 is formed between the compressed product aggregate S ′ wound with F. Then, the trailing edge F ′ of the wound packaging film F is pushed by the newly expanded compressed product assembly S ′ so as to be hooked on the step, so that it is wound on the guide tube 34 of the packaging film F. The portion thus placed can be reliably pushed out of the guide tube 33 and attached onto the compressed product assembly S.
[0077]
Further, since the compressed product assembly S is intermittently extruded from the tip of the guide tube 33, the packaging film F is perpendicular to the compressed product assembly S and the guide tube 33 except for the portion wound at the time of the extrusion. Is wound more strongly than the case of continuously extruding, so that the compressed product assembly S can be more suitably packaged.
[0078]
Further, each time the packaging film F is wound, the compressed product aggregate S is pushed out by a distance corresponding to the difference L3 between the depth L1 of the corner notch 34 and the depth L2 of the side notch 111. After the compressed product assembly S is extruded, the trailing edge F ′ of the packaging film F is positioned on the back end 111a of the side notch 111, so that the side until the packaging film F is wound next time. Since the part notch 111 is covered with the packaging film F, the bulge of the compressed product assembly S can be minimized while suppressing the frictional resistance between the guide tube 33 and the packaging film F.
[0079]
In addition, the string-like body 12 is wound in a state of being caught by the corner protrusion 112, and then removed from the compressed product aggregate S by pushing out the compressed product assembly S. It is possible to alleviate the difficulty of moving the packaging film F wound around the bag.

In addition, detection rollers 123 and 124 are disposed on the traveling paths of the packaging film F and the string-like body 12, respectively, and a generator (not shown) is connected to each of them. And when there is no output of each generator, the traveling detection means which each detects that the packaging film F and the string-like body 12 are not traveling is provided (not shown). The travel detection means is composed of a computing unit such as a CPU.
[0082]
A first gear 135 is fixed to a rotating shaft 143 fixed to the main frame 20 and rotatably held by the bracket 142. The first gear 135 is engaged with a second gear 136 that is pivotally supported by the bracket 142, and an arm 137 is fixed to the second gear 136. The arm 137 is configured such that a rear half 137b is rotatably connected to a front half 137a fixed to the side surface of the gear 136 so as to extend in the radial direction from the axis thereof, and a rear end of the rear half 137b is A sliding member (only part of which is shown in the figure) 139 is slidably engaged in a direction perpendicular to the extending direction. The sliding member 139 is formed in an annular shape coaxial with the turning wheel, and is disposed on the base frame 102 (see FIG. 1) so as to be parallel to the rotation surface of the turning wheel and slidable in the axial direction of the turning wheel. The piston rod 140 of the air cylinder is connected to the sliding member 139 (not shown). The air cylinder is disposed on the base frame such that the piston rod 140 advances and retreats in the axial direction of the swivel wheel. Accordingly, when the piston rod 140 advances from the solid line position in FIG. 15 to the two-dot chain line position, the arm 137 bends so that the front half 137a rises at a steep angle, whereby the second gear moves in the right direction in the drawing. Rotate. Then, the first gear 135 rotates in the left direction of the drawing, and the main frame 20, and consequently the string film roll 23 and the packaging film roll 26 rotate together with the first gear 135, and the string film roll 23 and The packaging film roll 26 is in an upright state. Then, when the piston rod 140 moves backward, the reverse operation is performed.
[0083]
According to the present embodiment configured as described above, the squeezing roller 25 for making the string film F1 into the string-like body 12 is arranged in front of the tension roller 121, so that it is compared with the string film F1. In order to apply the back tension to the string-like body 12 having a high tensile strength, the string-like body 12 has a higher tension than the case where the back tension is applied to the string-like film F1 as in the first embodiment. The cutting frequency of the material can be reduced.
[0084]
Moreover, since the presence or absence of the running of the packaging film F and the string-like body 12 is detected based on the presence or absence of the output of the generator connected to the detection roll, the cutting of the packaging film F and the string-like body 12 and the roll The end can be detected with a simple configuration.
[0085]
Furthermore, since the attitude of the packaging member supply device 108 is changed by the air cylinder, the configuration can be simplified as compared with the case of changing by the motor as in the first embodiment.
Embodiment 4

[0092]
Moreover, the securing member should just be a thing which can secure a packing object, for example, may use a binding band, a wire, etc.
[0093]
Moreover, as a belt-shaped packaging member, a tape-shaped or web-shaped one can be used.
[0094]
