Description

The present invention relates to a label mounting device for mounting a label on a container.

Various label mounting devices for mounting labels on containers have been proposed. Patent Document 1 discloses an example of a conventional label mounting device. In the label mounting device disclosed in the same document, labels are sequentially fed and mounted on the container from directly above the container conveyed by a conveyor or the like. The opening of the label is used as a part through which the upper part of the container is inserted.

In such a label mounting device, how to prepare the label is set in various ways. According to the document, a label is prepared by sequentially cutting a strip-shaped label material in a label mounting device. On the other hand, it is assumed that a method of preparing a plurality of labels created in advance in a state of being stacked on a label mounting device is used. In this case, for example, since the label is formed by a dedicated label forming device provided at another place, there is an advantage that the label forming efficiency can be improved. It is rational to arrange the stacked labels vertically upward with respect to the portion where the label of the label mounting device is fed out. However, when replenishing a new label in such a configuration, there is a problem that the work of replenishing the label is forced at a relatively high place.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

1 to 4 show a label mounting device based on the first embodiment of the present invention. The label mounting device A1 of the present embodiment includes a container transport device 12, a label feeding device 20, a label breaking device 60, a label delivery device 70, a first label replenishing device 300, and a second label replenishing device 400. The label mounting device A1 is a device for mounting the label L on the container B. In the figure, the z direction is the vertical direction, and the x direction is the transport direction of the container B. Further, in FIG. 2, for convenience of understanding, the second label replenishment device 400 is omitted. The floor surface FL shown in the figure is an example of the surface on which the label mounting device A1 is installed, and the user of the label mounting device A1 generally operates the label mounting device A1 while standing upright on the floor surface FL.

The specific configuration of the container B is not particularly limited, and examples thereof include bottle-type containers such as PET bottles, containers with pumps containing shampoo and the like, pharmaceutical containers (ampols, vials, etc.), and other containers of various shapes. It may be various containers such as a resin container, a metal container, and a glass bottle.

FIG. 5 illustrates the label L used in the label mounting device A1. FIG. 5A is a plan view showing an example of the label L. As shown in FIG. 7, the label L is a neck-hanging label attached to the neck of the container B, and has a substantially rectangular shape in which four corners are formed in an arc shape. The label L is formed of, for example, a sheet material such as synthetic resin, paper, cardboard, or synthetic paper, a laminate thereof, or a laminate of these and other sheets. Letters, figures, background colors, etc. are printed on the front surface (that is, the surface facing the opposite side of the container shoulder when the container is attached) and the back surface of the label L to display information for consumers who purchase the product. can do.

The label L of this example has an opening 2 and a perforation line of sight 3. The opening 2 is a portion that constitutes a space that penetrates the label L in the thickness direction. In the illustrated example, a through hole 2a is shown as a specific example of the opening 2. The through hole 2a is provided substantially in the center of the label L, and has, for example, an oval shape (or a track shape). The perforation line 3 is provided to partially break the label L. In the illustrated example, the perforation line 3 has a portion extending in the x direction connected to the through hole 2a and a portion extending from the portion on both sides in the y direction, but the shape of the perforation line 3 is not particularly limited. The perforation line 3 is a line that is broken before the label L is attached to the container B by the label breaking device 60 described later.

Of the label L, the portion of the through hole 2a sandwiched between the perforations 3 on both sides in the y direction is the engaging portion 4. The engaging portion 4 is a portion for preventing the label L from coming off the container B when the label L is attached to the container B. The engaging portion 4 also functions as a display portion by coming into contact with the container B and standing up.

FIG. 5B shows another example of label L. The label L of this example is an example in which the opening 2 includes a through hole 2a and a plurality of cutting lines 2b. The cutting line 2b is a linear portion having no clear area in a plan view, but is an example of a portion forming a space penetrating the label L in the thickness direction. That is, the cutting line 2b constitutes an opening 2 that clearly appears in the appearance of the label L as in the through hole 2a when a force is applied to the label L or is deformed. In this example, the portion between the plurality of cutting lines 2b is the engaging portion 4. The label L of this example does not have a perforation line or the like that is broken by the label breaking device 60. As described above, the label mounting device A1 is a device for appropriately feeding out the label L on which the opening 2 is formed, and the label L may or may not be provided with the perforation line 3.

FIG. 5 (c) shows yet another example of label L. In the label L of this example, only a plurality of cutting lines 2b are formed as the openings 2. In the illustrated example, a plurality of cutting lines 2b form an H-shape, but the arrangement of the cutting lines 2b is not particularly limited. As described above, even the label L in which the through hole 2a is not formed as the opening 2 can be attached to the container B by going through the steps described later.

FIG. 5D shows yet another example of label L. The label L of this example is not provided with the opening 2, but is provided with only the perforation line 3. In this case, as the label mounting device A1, the label breaking device 60 described later is indispensable.

Further, in FIGS. 5A, 5B, C, and D, the four corners of the label L are formed in an arc shape, but the corners may be substantially right angles. , A part of the corner portion may be partially cut out, and various shapes can be obtained. When such a label L is attached to the neck of the container B, the tongue piece-shaped engaging portion 4 of the label L is pressed against the container B, so that the attached state of the label L becomes stable. In the following description, a case where the label L shown in FIG. 5A is used will be described.

First, the configurations and operations of the container transport device 12, the label feeding device 20, the label breaking device 60, and the label delivery device 70, which are device portions for continuously mounting the label L on the container B, will be described below.

The container transport device 12 continuously transports a container B such as a PET bottle in the x direction. The container transport device 12 can be configured by a belt conveyor or the like that moves the container B in the container transport direction along the x direction while placing the container B on the container B. Further, the container transport device 12 has a pair of bars 14a and a pair of bars 14b. The pair of bars 14a guide the container B from both sides in the y direction, which is perpendicular to the x direction and the z direction. The pair of bars 14b are provided below the pair of bars 14a in the z direction, and guide the container B from both sides in the y direction. In addition, unlike this embodiment, a configuration having only a pair of bars may be used. Further, the container transport device 12 may include a plurality of pairs of positioning guides that move in synchronization with the belt conveyor.

The label feeding device 20, the label breaking device 60, the label delivery device 70, and the label transport device 80 are installed side by side in the x direction above the container transport device 12.

The label feeding device 20 is a device that feeds the labels L one by one toward the label breaking device 60. As shown in FIGS. 2 and 8 to 10, in the present embodiment, the label feeding device 20 includes a label accommodating portion 22, a feeding roller 24, support rollers 31, 32, and a support shaft 33. When the label breaking device 60 is not provided, the label feeding device 20 may be configured to feed the label L to, for example, the label delivery device 70 or the label transport device 80.

The label accommodating portion 22 accommodates a plurality of stacked labels L. In the present embodiment, the plurality of labels L are stacked in a state along the z direction in which the thickness direction is the vertical direction, and are housed in the label accommodating portion 22 in this state. A feeding opening 28 is formed in the label accommodating portion 22. The feeding opening 28 is a portion of the label accommodating portion 22 that opens at the lower end in the z direction. One side of the plurality of labels L housed in the label accommodating portion 22 located at the lowest position is exposed from the feeding opening 28. In the present embodiment, the label L located at the lowest position is the frontmost label L to be fed next. In the present embodiment, in the lower portion of the label accommodating portion 22 in the z direction, the plurality of labels L are configured to be displaced forward in the x direction as they go downward in the z direction. As a result, the vertically adjacent labels L are displaced in the x direction, so that the degree of adhesion between the labels L is reduced. As a result, the operation of feeding out the labels L one by one can be performed more reliably.

The support rollers 31 and 32 and the support shaft 33 are arranged directly below the label accommodating portion 22, and partially cover the feeding opening 28 of the label accommodating portion 22. The support rollers 31 and 32 and the support shaft 33 can be rotated by being supported by, for example, a side wall of the label accommodating portion 22 via a rolling bearing. The support roller 31 and the support roller 32 are arranged side by side in the x direction. The support shaft 33 has a smaller diameter than the support rollers 31 and 32, and is arranged in a narrow gap between the support roller 32 and the feeding roller 24. In the illustrated example, all of the support rollers 31, 32 and the support shaft 33 are arranged, which is an example of the configuration example. One or more of the support rollers 31 and 32 and the support shaft 33 may be selected and adopted depending on the size and shape of the label L and the state of feeding by the feeding roller 24. As a suitable configuration example for feeding out the label L, a configuration including only the support roller 31 can be mentioned. In such a configuration, the ratio of the weight of the plurality of labels L to the feeding roller 24 becomes large, and it can be expected that the feeding force of the feeding roller 24 is increased. Further, in this example, the case where the support rollers 31 and 32 and the support shaft 33 are rotatable has been described, but the support shaft 33 may be configured to be non-rotatable. Further, a vibrating device (not shown) may be attached to the label accommodating portion 22. By vibrating the label L in the label accommodating portion 22 by the vibrating device, air enters between the labels L, and it is suppressed that a plurality of labels L are simultaneously sent out from the label accommodating portion 22.

The feeding roller 24 is for feeding the lowest (front) label L in the x direction. The feeding roller 24 has a roller shaft 241 and a pair of contact portions 242 and a non-contact portion 244.

The pair of contact portions 242 are separated from each other in the y direction, and are located on both sides of the through hole 2a of the label L at the lowermost (frontmost) portion of the label accommodating portion 22. The diameter of the contact portion 242 is a size that contacts the lowermost (frontmost) label L at least in a state where the label mounting device A1 is operating. In the present embodiment, the pair of contact portions 242 are made of separate members from each other, and are fixed to the roller shaft 241 by a pair of fixing blocks 245. The pair of fixing blocks 245 are fixed to the roller shaft 241 by fastening bolts, for example, and can move in the y direction with respect to the roller shaft 241 by loosening the bolts. As a result, the positions of the pair of contact portions 242 in the y direction with respect to the roller shaft 241 can be adjusted. The position of only one of the pair of contact portions 242 may be adjustable with respect to the roller shaft 241. The material of the contact portion 242 is not particularly limited, and a high friction material such as resin and rubber or a metal such as aluminum can be appropriately used. From the viewpoint of not causing significant wear even after the contact portion 242 comes into contact with the plurality of labels L, the contact portion 242 is preferably made of metal, and the surface is preferably hardened by surface treatment or the like. is there.

In the present embodiment, a plurality of protrusions 243 are formed on the peripheral surface of the contact portion 242. The plurality of protrusions 243 are an example of the high friction shape of the present invention. Each of the plurality of protrusions 243 is, for example, a pramid-shaped (square pyramid-shaped) protrusion. Further, the plurality of protrusions 243 are arranged in a matrix along the axial direction and the circumferential direction of the feeding roller 24. By providing the protrusion 243, the force for feeding out the label L can be strengthened by the feeding roller 24.

The non-contact portion 244 is composed of a portion of the roller shaft 241 located between the pair of contact portions 242. The non-contact portion 244 is a portion that does not come into contact with the lowermost (frontmost) label L.

The feeding roller 24 is preferably driven so as to feed the label L, and in the present embodiment, it is driven by a motor 249 connected to the roller shaft 241.

FIG. 14 shows a modified example of the feeding roller 24. In this modification, the feeding roller 24 has only one contact portion 242 and is not provided with the non-contact portion 244. Such a contact portion 242 is preferably used when handling a label L in which the opening 2 is not provided, for example, as shown in FIG. 5 (d).

As shown in FIGS. 2 and 11, the label breaking device 60 is arranged adjacent to the downstream side of the guide plate 44 in the x direction. The label breaking device 60 functions to break the perforation line 3 when the perforation line 3 is formed on the label L. The label breaking device 60 includes a transfer roller 62 and a breaking roller 64. One of the transfer roller 62 and the breaking roller 64 is connected to a motor (not shown) to be a drive roller that is rotationally driven in the direction of the arrow in the figure, and the other of the transfer roller 62 and the breaking roller 64 is connected to the drive roller by a gear and is driven to rotate. Can be configured as a driven roller.

The transfer roller 62 has a shaft 63 and two nip rollers 66 fixed on the shaft 63 at predetermined intervals. At least the outer peripheral surface of the nip roller 66 is preferably formed of a high friction material such as rubber which is not slippery with respect to the label L.

The breaking roller 64 has a shaft 65 arranged in parallel with the shaft 63 of the transfer roller 62, and a transfer breaking roller portion 68 fixed on the shaft 65. Like the nip roller 66, at least the outer peripheral surface of the transfer breaking roller portion 68 is preferably formed of a high friction material such as rubber which is not slippery with respect to the label L.

The transfer breaking roller portion 68 has a pair of transfer portions 681 and a breaking portion 682. The pair of transfer portions 681 are separately arranged on both sides in the y direction, and in the illustrated example, have a perfect circular shape having a constant outer shape. The broken portion 682 is provided between the pair of transfer portions 681. The fractured portion 682 has a shape in which a part in the circumferential direction protrudes outward in the radial direction from the pair of transfer portions 681. Of the broken portion 682, the portion other than the protruding portion has a partial circular shape having the same shape as the transfer portion 681.

The label delivery device 70 includes, for example, transport belts 71 and 72. The transport belts 71 and 72 are endless belt members that are rotationally driven while being in contact with each other. The label delivery device 70 includes a pair of transport belts 71 and 72 arranged apart from each other in the y direction. In FIG. 2, only the transport belts 71 and 72 on one side in the y direction are shown. The transport belts 71 and 72 move the label L received from the label breaking device 60 toward the label transport device 80 while sandwiching both side portions of the through holes 2a of the label L.

The label delivery device 70 has first and second sensors (not shown). The first sensor detects the label L at a predetermined position and transmits the label detection signal to a control unit (not shown). The control unit that receives the label detection signal drives and controls the transport belts 71 and 72 to move the label L to the downstream end and make it stand by. The second sensor detects the position of the container B at a predetermined position and transmits a container detection signal to the control unit. The control unit that receives the container detection signal drives and controls the upper and lower transport belts 71 and 72, so that the label L waiting at the downstream end is delivered to the label transport device 80 at the timing when it can be attached to the container B. It has become like. With these first and second sensors, the label L can be attached to the container B even when the pitch between the transported containers B is not a constant pitch.

The label transport device 80 is a device that transports the label L delivered from the label delivery device 70 at the label receiving position α to the label mounting position β. The label transfer device 80 of the present embodiment includes a pair of endless belt members 81, a plurality of pulleys 82, a pair of low pressure chambers 87, and a pair of belt facing members 91. FIG. 12 is a bottom view of the label transport device 80 as viewed from below in the z direction.

The pair of low pressure chambers 87 are arranged apart from each other in the y direction. The low pressure chamber 87 has an internal space set to have a lower atmospheric pressure than the outside. Each low pressure chamber 87 is made of a material such as resin or metal. The low pressure chamber 87 extends obliquely from the label receiving position α to the label mounting position β. The low pressure chamber 87 is open on the lower side. The lower opening of the low pressure chamber 87 is closed by an endless belt member 81 that moves from the label receiving position α to the label mounting position β. The low pressure chamber 87 is connected to, for example, a vacuum pump (not shown). Due to the operation of this vacuum pump, the air pressure in the internal space of the low pressure chamber 87 becomes lower than the external pressure.

A pair of pulleys 82 are arranged on both sides of the low pressure chamber 87 in the x direction. One of the pair of pulleys 82 is driven by a motor (not shown). Alternatively, the endless belt member 81 may be driven by a driving means other than the pair of pulleys 82. The endless belt member 81 is hung around a pair of pulleys 82 and closes the lower opening of the low pressure chamber 87. A plurality of suction holes 811 are formed in the endless belt member 81. The plurality of suction holes 811 have, for example, a circular shape or an elliptical shape, and are arranged in the longitudinal direction of the endless belt member 81.

The pair of belt facing members 91 are arranged to face the lower surface 83 of the pair of endless belt members 81. Each belt facing member 91 is made of metal, resin, or the like. The belt facing member 91 is arranged substantially parallel to the lower surface 83 of the endless belt member 81. The gap between the belt facing member 91 and the lower surface 83 of the endless belt member 81 is larger than the thickness of the label L, preferably slightly larger than the thickness of the label L.

In this example, the case where the belt facing member 91 is arranged substantially parallel to the lower surface 83 of the endless belt member 81 has been described, but the belt facing member 91 is located on the lower surface 83 of the endless belt member 81 in the z direction. It does not have to be arranged substantially parallel to the lower surface 83 of the endless belt member 81.

Next, mounting of the label L by the label mounting device A1 will be described below.

As shown in FIGS. 2 and 8 to 10, a plurality of contact portions 242 of the feeding roller 24 are housed in the label accommodating portion 22 by rotationally driving the feeding roller 24 in the label feeding device 20. Attempts are made to move the lowest (front) label L of the labels L in the x direction. At this time, as shown in FIG. 10, in the lowermost (frontmost) label L, the pair of contact portions 242 are brought into contact with both side portions of the through hole 2a as the opening portion 2 in the y direction. As a result, the lowest (front) label L is unwound so that the hatched strip-shaped portion in FIG. 10 is scraped out by the pair of contact portions 242. In the feeding of the label L, since the non-contact portions 244 of the feeding roller 24 face each other in the through holes 2a of the label L and the portions of the through holes 2a located on both sides in the x direction, the feeding rollers are exposed to these parts. 24 does not abut.

Then, as shown in FIGS. 2 and 11, the unwound label L is guided to the label breaking device 60. The label L is transferred in the x direction while the nip roller 66 and the transfer portion 681 sandwich both side portions of the through hole 2a in the y direction. At this time, since the transfer breaking roller portion 68 is provided with the breaking portion 682, the breaking portion 682 is pressed against the central portion of the label L. As a result, the perforation line 3 of the label L is broken, and the insertion portion 2A shown in FIG. 6 is formed. Further, the engaging portion 4 is in an upright state in the z direction. The broken label L is transferred to the label delivery device 70.

The label delivery device 70 to which the broken label L has been transferred transfers the label L to the label receiving position α. Using the first sensor and the second sensor provided in the label delivery device 70, for example, at the label receiving position α, the label L transferred by the label delivery device 70 and the container B transferred by the container transfer device 12 , Aligned in the x direction. As a result, the label delivery device 70 delivers the label L to the label transfer device 80 at the timing when the label L can be attached to the container B transported in the x direction.

The label transport device 80 transports the label L received from the label delivery device 70 at the label receiving position α to the label mounting position β. Since the internal space of the low pressure chamber 87 is negative pressure, the label L is attracted to the suction hole 811 on the lower surface of the endless belt member 81 at the label receiving position α. In this state, the label L is conveyed from the label receiving position α to the label mounting position β by driving the pair of endless belt members 81 by the pulley 82. When the label L is conveyed to the label mounting position β, the pair of endless belt members 81 attract and hold both side portions of the through hole 2a in the label L in the y direction. As a result, the engaging portion 4 does not receive a force from the endless belt member 81, and the habit of tilting upward and standing up on the engaging portion 4 is maintained.

By transporting the broken label L diagonally downward at the label mounting position β, the label L approaches the head C of the container B transported at the z-direction position of the label L. Then, as shown in FIG. 7, the insertion portion 2A formed by the breakage of the perforation line 3 is inserted into the head portion C of the container B. As a result, the label L is attached around the neck portion located below the head C in the container B.

At the label mounting position β, the container B on which the label L is mounted is sequentially conveyed in the x direction. By continuously executing the above steps for the containers B that are sequentially conveyed, the labels L can be attached to the plurality of containers B.

Next, the configuration and operation of the first label replenishment device 300 and the second label replenishment device 400 will be described below. In the first label replenishment device 300 and the second label replenishment device 400, the continuous label L is attached to the container B by the container transport device 12, the label feeding device 20, the label breaking device 60, and the label delivery device 70 described above. It is a device provided for continuous operation over a longer period of time.

The first label replenishing device 300 is a device that supplies a plurality of labels L stacked in the label accommodating portion 22 of the label feeding device 20. 1 to 4 and in the present embodiment, the first label replenishment device 300 has a plurality of first label storage units 310 and a rotation drive mechanism 320.

The plurality of first label storage units 310 are for storing a plurality of stacked labels L to be replenished in the label storage unit 22 of the label feeding device 20. In the illustrated example, the plurality of first label stockpiling units 310 are arranged on a circular orbit at equal pitches. The number of the plurality of first label storage units 310 is not particularly limited, and any configuration may be used as long as the label L can be continuously attached to the container B for a longer period of time. The number of the plurality of first label storage units 310 in the illustrated example is an example shown for the convenience of understanding the structure and operation of the label mounting device A1, and is used as the actual number of the plurality of first label storage units 310. For example, about 12 pieces can be mentioned. The arrangement of the plurality of first label storage units 310 is not limited to the arrangement on the circular orbit. The first label storage unit 310 is not particularly limited as long as it can store a plurality of stacked labels L, and in the illustrated example, it has a rectangular frame shape or a U shape surrounding the label L in the z direction.

FIG. 21 shows an operation of raising the second label storage unit 410 located at the second supply position P2 upward in the z direction by the storage unit elevating mechanism 430. Prior to this ascent, as shown in FIG. 22, an empty first label storage unit 310 is arranged at the second supply position P2, and the shutter 325 is opened. FIG. 22 is a plan view of a main part showing the second label storage unit 410, the label lifting mechanism 440, and the shutter 325. In the illustrated example, the shutter 325 is composed of a pair of shutter arms 326 and a drive cylinder 328. The pair of shutter arms 326 are located on both sides in the y direction with respect to the opening 322 of the support plate 321 of the rotation drive mechanism 320, and are portions that open and close in the y direction. In the illustrated example, the pair of shutter arms 326 are formed with an inner edge 327. The inner end edge 327 is for creating a space through which the second label storage portion 410 located at the second supply position P2, particularly the convex portion 415 and the label L, is inserted when the pair of shutter arms 326 is in the open state. It is a thing. The drive cylinder 328 is a drive source for the shutter 325, and in the illustrated example, includes an air cylinder that opens and closes a pair of shutter arms 326 in the y direction.

In FIG. 22, when the shutter 325 is in the open state, the second label stockpile portion 410, particularly the convex portion 415, can be inserted between the inner end edges 327 of the pair of shutter arms 326. In this state, as shown in FIG. 20, the drive cylinder 431 of the storage unit elevating mechanism 430 is driven, and the second label storage unit 410 is pushed up from below in the z direction by the push rod 432. As a result, the second label storage unit 410 located at the second supply position P2 rises, and the convex portion 415 of the second label storage unit 410 enters the opening 322 of the support plate 321.

Next, as shown in FIG. 21, the drive cylinder 441 of the label lifting mechanism 440 is driven to raise the shaft 442. As shown in FIG. 22, in the z-direction view, the contact portion 443 is set to a size, shape, and position capable of inserting the opening 412 of the bottom plate 411 of the second label storage portion 410. Therefore, when the contact portion 443 rises due to the rise of the shaft 442, the contact portion 443 passes through the bottom plate 411 of the second label storage portion 410 and a plurality of labels L stored in the second label storage portion 410. Contact from below in the z direction. Further, when the drive cylinder 441 is driven and the shaft 442 is raised, the plurality of labels L stored in the moving mechanism 420 are raised. As a result, the plurality of labels L are inserted into the first label storage unit 310 located at the second supply position P2 through the open shutter 325 and the opening 322 of the support plate 321 in order from the one located above in the z direction. Will be done. When the shaft 442 is further raised, the contact portion 443 approaches the support plate 321. As shown in FIG. 22, the contact portion 443 of the convex portions 444 can enter between the inner end edges 327 of the pair of shutter arms 326 of the shutter 325. When the drive cylinder 441 is driven to the upper end, the upper end surface of the convex portion 444 rises to a position substantially equal to the upper end surface of the support plate 321. As a result, all of the plurality of labels L are inserted into the first label storage unit 310.

Next, the shutter 325 is closed to bring it into the state shown in FIG. In this state, the inner end edges 327 of the pair of shutter arms 326 of the shutter 325 approach each other in the y direction, but still have a size and shape capable of including the convex portion 444 of the contact portion 443. Therefore, by locating the contact portion 443 (convex portion 444) at the upper end, the state in which the plurality of labels L are inserted into the first label storage portion 310 by the contact portion 443 (convex portion 444) is maintained as it is. It is possible to keep it. On the other hand, the inner edge 327 of the pair of shutter arms 326 of the shutter 325 defines a space smaller than the label L in the z-direction view. That is, the label L has a positional relationship that overlaps with the pair of shutter arms 326 in the z-direction view. Therefore, the plurality of labels L inserted into the first label storage unit 310 are supported by the shutter 325 without falling. Therefore, when the shaft 442 and the contact portion 443 are lowered by driving the drive cylinder 441 after the shutter 325 is closed, the shutter 325 has a plurality of labels L inserted into the first label storage portion 310. It will be supported. As a result, the supply of the plurality of labels L from the second label storage unit 410 of the second label supply device 400 to the first label storage unit 310 of the first label supply device 300 at the second supply position P2 is completed.

The number of labels L that can be accommodated in the label accommodating portion 22 of the label feeding device 20 is, for example, about 1,800. Therefore, when only a plurality of labels L housed in the label storage unit 22 are used, the continuous duration of the mounting operation is about 2 minutes at the shortest. The first label storage unit 310 of the first label replenishment device 300 can store about 1,800 labels L like the label storage unit 22, for example. When the first label replenishment device 300 has twelve first label storage units 310, the first label replenishment device 300 can store up to about 21,600 labels L. By sequentially replenishing the label L from the first label replenishing device 300 to the label accommodating portion 22 of the label feeding device 20, the continuous duration of the labeling operation of the label mounting device A1 can be extended by at least 24 minutes. The second label storage unit 410 of the second label replenishment device 400 can store about 1,800 labels L like the label storage unit 22 and the first label storage unit 310, for example. When the second label replenishment device 400 has three second label storage units 410, the second label replenishment device 400 can store up to about 5,400 labels L. Further, the first label storage unit 310 of the first label replenishment device 300 is arranged so that the lower end thereof is located at a height of, for example, about 2,000 mm from the floor surface FL. On the other hand, the second label storage unit 410 of the second label replenishment device 400 is arranged so that its upper end is present at a position lower than at least 2,000 mm in a state where it is not raised by the storage unit elevating mechanism 430. There is.

Next, the operation of the label mounting device A1 will be described.

According to the present embodiment, the label accommodating portion 22 of the label feeding device 20 can be replenished with the labels L stored in the plurality of first label stockpiling units 310 of the first label replenishing device 300 at the first replenishment position P1. is there. As a result, the continuous duration of the operation of attaching the label L to the container B can be extended. Further, the plurality of first label storage units 310 of the first label replenishment device 300 can be replenished with the plurality of labels L stored in the second label storage unit 410 of the second label replenishment device 400 at the second replenishment position P2. Is. The second label stockpile unit 410 is located directly below the first label stockpile unit 310 at the second replenishment position P2, and its entire position is lower than the first label stockpile unit 310. Therefore, even if the user standing on the floor does not reach the first label storage unit 310, the second label storage unit 410 is at a height that allows the user to reach the floor surface while standing upright. Therefore, it is possible for the user to perform the replenishment work of a plurality of labels L to the second label storage unit 410 while standing on the floor surface or a relatively low workbench placed on the floor surface, and the work is performed at a high place. It is possible to eliminate the need for replenishment work of the label L in.

The first supply position P1 and the second supply position P2 are at different positions in the z-direction view. Therefore, an operation of replenishing a plurality of labels L from the first label storage unit 310 of the first label replenishment device 300 at the first replenishment position P1 to the label accommodating unit 22 of the label feeding device 20 and the second replenishment position P2. It is possible to perform the replenishment operation from the two-label storage unit 410 to the first label storage unit 310 and the replenishment work to the second label storage unit 410 in parallel. This is preferable for extending the continuous duration of the labeling operation of the label mounting device A1.

Since the plurality of first label storage units 310 are arranged on the circular orbit, when the plurality of first label storage units 310 are rotated by the rotation drive mechanism 320, the first label storage unit located at the first supply position P1 is stored. An operation of moving the unit 310 to the second supply position P2 opposite to the first supply position P1 or moving the first label storage unit 310 at the second supply position P2 to the first supply position P1. It can be done smoothly. Since the first replenishment position P1 and the second replenishment position P2 are located on opposite sides in the radial direction of the circular orbits of the plurality of first label storage units 310, the first label replenishment device 300 at the first replenishment position P1 is located. The operation of replenishing a plurality of labels L from the label storage unit 310 to the label storage unit 22 of the label feeding device 20, the replenishment operation of the second label storage unit 410 to the first label storage unit 310 at the second replenishment position P2, and the second operation. It is possible to avoid interference with the replenishment work for the 2 label storage unit 410.

Due to the configuration in which the plurality of second label storage units 410 can be moved by the moving mechanism 420, while supplying the plurality of labels L from the second label storage unit 410 to the first label storage unit 310 at the second supply position P2, Other than this, it is possible to perform the work of supplying a plurality of labels L to the second label storage unit 410 in parallel. As a result, it becomes possible for the user to replenish the label L to the second label storage unit 410 at a timing in a wider time zone.

In addition, in order to more reliably attach the label L after attaching the label L conveyed by the label conveying device 80 to the container B, the label L is attached to the label attaching device A1 from above with respect to the container B. A label pressing device that presses downward may be further provided.
