The label winder 121 includes a pair of rotating plates 121a and four winding shafts 121b extending over the pair of rotating plates 121a. The outer edge portion 4b of the back surface side label 4 engages with the four winding shafts 121b and is wound between the two rotating plates 121a.

The guide roller 126 and the label winder 121 are rotationally driven in both forward and reverse directions in synchronization with the first platen roller 114 and the second platen roller 115 of the double-sided printing apparatus 110. As a result, when the label winder 121 winds the outer edge portion 4b of the back surface side label 4, the double-sided printing label 3 or the outer edge portion 4b of the back surface side label 4 is prevented from being loosened or torn due to tension. It has become.

When the outer edge portion 4b of the back surface side label 4 is wound by the label winder 121, the outer edge portion 4b is bent at the tip position of the release plate 123 and is sequentially peeled off from the front surface side label 5. The inner portion 4c of the back surface side label 4 is not peeled off from the front surface side label 5 even if the outer edge portion 4b is peeled off from the front surface side label 5, and is separated from the outer edge portion 4b by the notch 4a. In this way, the tag label 2 having the front side label 5 and the inner side portion 4c of the back side label 4 is issued separately from the double-sided printing label 3.

Next, a label sticking mechanism 200 for sticking the tag label 2 issued by the label issuing device 100 to the baggage 1 will be described.

As shown in FIGS. 1 and 2, the label affixing mechanism 200 receives the transport mechanism 210 for transporting the tag label 2 issued from the label issuing device 100 and the tag label 2 conveyed by the transport mechanism 210, and receives the load 1 It is provided with a sticking mechanism 240 for sticking to.

A plurality of (two) conveyors 211 (conveyors) are provided side by side in the conveyor 210. The conveyor 211 is a conveyor that conveys the tag label 2, which is separated from the double-sided printing label 3 by the label peeling mechanism 120, to the delivery position to the sticking mechanism 240. The number of conveyors 211 provided in the transport mechanism 210 is not limited to two, and can be arbitrarily set according to the size of the tag label 2 and the like.

The conveyor 211 is a conveyor drive motor that drives a belt 212 for transporting the tag label 2, rollers 214 and 215 on which the belt 212 is hung, and one roller 214 via a belt, gears, or the like. 213 and.

The belt 212 circulates in synchronization with the first platen roller 114, the second platen roller 115, and the label winder 121 of the double-sided printing apparatus 110. As a result, the tag label 2, which is issued separately from the double-sided printing label 3, is smoothly transferred from the label issuing device 100 to the conveyor 211.

A label detection sensor 216 is provided in the vicinity of the conveyor 211. The label detection sensor 216 is a reflective photoelectric sensor that detects the presence or absence of the tag label 2. The controller 290 controls the operation of the conveyor 211 so as to convey the tag label 2 to the delivery position to the sticking mechanism 240 in response to the detection signal of the label detection sensor 216.

The adhesive layer 5e is exposed on the back surface of the tag label 2 because the outer edge portion 4b of the back surface side label 4 is peeled off from the front surface side label 5. In response to this, a release agent layer (not shown) is provided on the surface of the belt 212. As a result, the tag label 2 is prevented from sticking to the belt 212 via the adhesive layer 5e. Further, the adhesive of the adhesive layer 5e is prevented from adhering to the belt 212.

The conveyor 211 may be provided with a negative pressure generator in which a large number of holes are provided in the belt 212 and a negative pressure is generated in each hole. In this case, since the tag label 2 is transported in a state of being attracted to the belt 212, the tag label 2 is prevented from slipping or misaligning on the belt 212.

The transport mechanism 210 is provided with a push-up portion 220 that pushes up the tag label 2 transported by the transport conveyor 211 from the transport conveyor 211.

As shown in FIG. 2, the push-up portion 220 includes a plurality of (six) blades 221 arranged side by side with the conveyor 211, and an actuator 222 for raising and lowering each blade 221.

As shown in FIG. 6, the push-up portion 220 is provided with three sets of two blades 221 as one set. Each set of two blades 221 is arranged so as to sandwich each conveyor 211 so as to abut on both sides and the center of the tag label 2.

As shown in FIGS. 7 and 8, each blade 221 is fixedly attached to the push-up frame 225. The push-up frame 225 is driven in the vertical direction by the actuator 222.

As a result, each blade 221 is retracted below the belt 212 of the conveyor 211 as shown in FIGS. 8 and 9A, and protrudes upward from the belt 212 of the conveyor 211 as shown in FIG. 9B. It goes up and down between the protruding position where the label 2 is lifted.

The thin plate-shaped blade 221 is arranged so as to extend along the side portion of the conveyor 211 and extend in the vertical direction (vertical direction).

The blade 221 has a tip 221a extending linearly above it. The width T1 (see FIG. 6) of the tip 221a is set smaller than the width T5 (see FIG. 5) of the pressure-sensitive adhesive layer 5e of the tag label 2 so as to make linear contact with the pressure-sensitive adhesive layer 5e.

A release agent layer (not shown) is provided on the surface of the tip 221a. This prevents the tag label 2 from sticking to the blade 221 via the adhesive layer 5e. Further, the adhesive of the adhesive layer 5e is prevented from adhering to the blade 221.

The two blades 221 are coupled via a plurality (two) spacers 224. The two blades 221 have a predetermined distance. Specifically, the blade installation width T2 (see FIGS. 6 and 7) provided with the tips 221a of the two blades 221 is set to be smaller than the suction width T3 (see FIGS. 6 and 7) of the suction pad 241 described later. Will be done.

In this way, the two blades 221 are arranged so as to face the suction pad 241. The number of blades 221 facing the suction pad 241 is not limited to two, and can be arbitrarily set according to the size of the suction pad 241 and the like.

Further, the label detection sensor 216 for detecting the presence or absence of the tag label 2 described above may be provided so as to be arranged between two blades 221 arranged side by side with each other. In this case, the label detection sensor can be arranged so as to face the center of the tag label 2. As a result, the label detection sensor 216 can accurately detect the presence or absence of the tag label 2 on the blade 221.

As shown in FIGS. 7 and 8, the sticking mechanism 240 includes a plurality of (8) suction pads 241 (suction portions) for sucking the tag label 2, a pipe 242 to which each suction pad 241 is connected, and each pipe. It includes an elevating frame 245 to which 242 is attached. The pipe 242 is connected to the negative pressure generator via a pipe (not shown) to guide the negative pressure to the inside of the suction pad 241. The suction pad 241 is a suction portion that sucks the tag label 2 by a negative pressure. The number of suction pads 241 is not limited to eight, and can be arbitrarily set according to the size of the tag label 2 and the like.

The suction pad 241 is formed of an elastic material such as rubber. The suction pad 241 is elastically deformed by the negative pressure for sucking the tag label 2 and contracts in the axial direction (vertical direction).

The suction pad 241 is formed in a tubular shape having a bellows-shaped cross section, and has an annular suction surface 241a for sucking the tag label 2. The diameter of the suction surface 241a is the suction width T3 for sucking the tag label 2. The suction pad 241 is not limited to this shape, and may be elastically deformed and expanded or contracted by a pressure change generated inside the suction pad 241.

As shown by the alternate long and short dash line in FIG. 6, the eight suction pads 241 are arranged so as to face the outer edge portion 5b of the tag label 2.

Further, the plurality of (3 or 2) suction pads 241 arranged in the left-right direction in FIG. 6 are arranged so as to face each of the three sets of blades 221 extending in the longitudinal direction (left-right direction in FIG. 6) of the tag label 2. Will be done.

As shown in FIGS. 7 and 8, the sticking mechanism 240 includes a support portion 250 that supports the tag label 2 that is sucked by the suction pad 241. When the suction pad 241 sucks the tag label 2 and contracts, the support portion 250 abuts and supports the tag label 2. As a result, the tag label 2 is restricted from loosening between the suction pads 241.

The support portion 250 includes a plurality of (two) elastic members 251 that abut on the tag label 2 that is attracted to the suction pad 241 and a plurality of (two) brackets 253 that attach the elastic members 251 to the elevating frame 245. ..

As shown by the alternate long and short dash line in FIG. 6, the two elastic members 251 are arranged so as to extend between the suction pads 241 arranged in three rows in the longitudinal direction (horizontal direction in FIG. 6) of the tag label 2. The number of elastic members 251 is not limited to two, and can be arbitrarily set according to the number of rows of suction pads 241.

The block-shaped elastic member 251 has a cubic outer shape and has a support surface 251a extending in the horizontal direction. The support surface 251a is provided so as to face the tag label 2, and is in contact with the tag label 2 that is attracted to each suction pad 241.

The elastic member 251 is formed of a porous material (sponge) having a large number of bubbles formed by foam molding using rubber such as ethylene propylene rubber (EDPM) as a raw material.

The elastic member 251 is attached by being joined to the lower surface of the bracket 253. The bracket 253 is fastened to the elevating frame 245 via a plurality of (two) bolts 254. By changing the position where the bracket 253 is fastened to the elevating frame 245, the attachment position of the elastic member 251 to the suction pad 241 is adjusted.

The elastic member 251 is attached so as to satisfy the following conditions.
In the non-adsorption state (free state) in which the suction pad 241 is not contracted due to negative pressure, the suction surface 241a of the suction pad 241 is lowered (separated) by a predetermined amount from the support surface 251a of the elastic member 251. To position.
In the suction state (elastic deformation state) in which the suction pad 241 is contracted due to negative pressure, the suction surface 241a of the suction pad 241 comes to substantially the same height as the support surface 251a of the elastic member 251. As a result, the suction surface 241a and the support surface 251a are arranged so as to extend on the same straight line with each other.

The suction pad 241 contracts by a predetermined amount (for example, about 2 mm) due to the negative pressure for sucking the tag label 2, so that the suction surface 241a for sucking the tag label 2 is below (separated from) the support surface 251a of the elastic member 251. ), It rises to a position at least at the same height as the support surface 251a of the elastic member 251.

As shown in FIG. 6, a label detection sensor 248 is provided between the two elastic members 251. The label detection sensor 248 is a reflective photoelectric sensor that detects the presence or absence of the tag label 2. The controller 290 determines that the tag label 2 is present in response to the detection signal of the label detection sensor 248, operates the moving mechanism 230 as described later, and attaches the tag label 2 to the luggage 1. If there is no tag label 2, the operation of the moving mechanism 230 is stopped.

As shown in FIG. 1, the moving mechanism 230 is movable along the fixed frame 231 and the horizontal rail 232 extending in the horizontal direction orthogonal to the transport direction of the roller conveyor 280 on the fixed frame 231 and the horizontal rail 232. A moving body 233 provided, an actuator (not shown) for driving the moving body 233, a vertical rail 234 extending in the vertical direction from the moving body 233, an elevating frame 245 provided so as to be vertically elevated along the vertical rail 234, and an elevating frame 245. An actuator (not shown) for driving the drive is provided.

The moving body 233 is moved by the actuator in the horizontal direction orthogonal to the transport direction of the roller conveyor 280. The moving body 233 has a label receiving position (two-dot chain line in FIG. 1) in which the sticking mechanism 240 is located on the transport mechanism 210 and a label sticking position (solid line in FIG. 1) in which the sticking mechanism 240 is located on the roller conveyor 280. Move between ,. The elevating frame 245 moves up and down with respect to the moving body 233 by an actuator.

As a result, the sticking mechanism 240 moves up and down at each of the position where the tag label 2 is received from the blade 221 and the position where the sticking mechanism 240 is stuck on the load 1 on the roller conveyor 280.

The roller conveyor 280 is provided with a stopper (not shown), and stops the luggage 1 at the label sticking position until the sticking of the tag label 2 to the luggage 1 is completed. When the attachment of the tag label 2 to the luggage 1 is completed, the stopper of the roller conveyor 280 is released, and the luggage 1 is transported to the downstream side.

Next, with reference to FIGS. 9A to 9F, an operation in which the tag label 2 is attached to the luggage 1 in the label attaching mechanism 200 will be described.

First, as shown in FIG. 9A, the conveyor 211 circulates the belt 212 and conveys the tag label 2 placed on the belt 212 to the delivery position of the affixing mechanism 240.

At this time, the blade 221 is in the retracted position lowered below the belt 212 and does not interfere with the conveyed tag label 2.

Subsequently, as shown in FIG. 9B, the blade 221 rises to the protruding position. As a result, the tip 221a of the blade 221 protrudes above the belt 212, and the tag label 2 is lifted away from the belt 212.

Subsequently, as shown in FIG. 9C, each suction pad 241 of the sticking mechanism 240 is lowered.

At this time, since the suction surface 241a of each suction pad 241 is below the support surface 251a of the elastic member 251 each suction pad 241 comes into contact with the tag label 2 before the elastic member 251 and is inside the suction pad 241. The tag label 2 is adsorbed by the negative pressure guided by.

When each suction pad 241 sucks the tag label 2, each suction pad 241 sandwiches the tag label 2 between the tip 221a of each blade 221. The tag label 2 is supported by linearly contacting the tip 221a of each blade 221.

Further, at this time, since the belt 212 is below the tip 221a of the blade 221, the adhesive layer 5e of the tag label 2 is prevented from being pressed against the belt 212.

In this way, when each suction pad 241 sucks the tag label 2, as shown in FIG. 9D, each suction pad 241 contracts due to negative pressure, and the suction surface 241a of each suction pad 241 is abbreviated as the support surface 251a of the elastic member 251. Come to the same height. As a result, the tag label 2 adsorbed on each suction pad 241 comes into contact with the support surface 251a of each elastic member 251 extending in the same straight line along with the suction surface 241a of the suction pad 241 so as to extend straight. Supported by.

Subsequently, the moving body 233 moves from the label receiving position (two-dot chain line in FIG. 1) to the label sticking position (solid line in FIG. 1).

Subsequently, as shown in FIG. 9E, the tag label 2 is affixed to the baggage 1 by lowering the sticking mechanism 240.

At this time, the suction surface 241a of the suction pad 241 extending on the same straight line and the support surface 251a of the elastic member 251 press the tag label 2. The tag label 2 is affixed to the affixed surface (upper surface) of the baggage 1 without wrinkles in a straightened state.

At this time, if the surface to which the luggage 1 is attached has undulations such as steps or inclinations, each suction pad 241 and each elastic member 251 elastically deforms following the shape of the surface to which the luggage 1 is attached. .. In this way, the tag label 2 is attached via the adhesive by pressing the adhesive layer 5e against the surface to be attached of the luggage 1 in a wide range.

Finally, as shown in FIG. 9F, after the sticking mechanism 240 is raised, the moving body 233 moves to the label receiving position (two-dot chain line in FIG. 1), and shifts to the operation of sticking the next tag label 2.

Next, comparative examples shown in FIGS. 10A, 10B, and 10C will be described. The sticking mechanism 240 according to this comparative example does not include the support portion 250, and a space is provided between the suction pads 241.

FIG. 10A shows an operation in which each suction pad 241 sucks the tag label 2. Since a portion for supporting the tag label 2 is not provided between the suction pads 241 when the operation of each suction pad 241 sucking the tag label 2 varies, the tag label 2 sucked on each suction pad 241. Does not extend straight and slack A occurs between the suction pads 241. In this case, as shown in FIG. 10B, the tag label 2 is affixed to the baggage 1 in a state where the slack A is generated by lowering the affixing mechanism 240. Therefore, as shown in FIG. 10C, wrinkles B are formed on the tag label 2 attached to the package 1.

In contrast to the above comparative example, in the present embodiment, as described above, the tag label 2 attracted to each suction pad 241 is supported in a state of being in contact with the support surface 251a of each elastic member 251 and extending straight. As a result, wrinkles are prevented from being generated on the tag label 2.

Next, the effect of this embodiment will be described.

According to the present embodiment, the label sticking device 10 receives the transport mechanism 210 for transporting the tag label 2 (label) and the tag label 2 transported by the transport mechanism 210, and attaches the label to the luggage 1 (adhesion). It is provided with a sticking mechanism 240.

The sticking mechanism 240 is provided between the plurality of suction pads 241 (suction portions) for sucking the tag label 2 by negative pressure and the plurality of suction pads 241 and is sucked by the plurality of suction pads 241. A support portion 250 for supporting the above.

Based on the above configuration, the tag label 2 sucked on the plurality of suction pads 241 is prevented from loosening by being supported by the support portion 250. Therefore, it is possible to prevent wrinkles from forming on the tag label 2 attached to the luggage 1. As a result, the characters, barcodes, and the like printed on the tag label 2 are accurately read at the time of shipment of the package 1. In addition, it is possible to prevent the tag label 2 from being torn or the like.

Further, the support portion 250 includes an elastic member 251 that is elastically deformed by an external force.

Based on the above configuration, when the tag label 2 is attached to the luggage 1, the elastic member 251 is elastically deformed by the reaction force received from the luggage 1 and the tag label 2 is pressed against the luggage 1. As a result, the adhesive layer 5e of the tag label 2 is brought into close contact with the luggage 1, and the tag label 2 is surely attached.

The support portion 250 is not limited to the above-described configuration, and may be configured by a support member that is not elastically deformed by an external force and an air cylinder that supports the support member in an advancing and retreating manner. In this case, when the tag label 2 is attached to the luggage 1, the air cylinder contracts due to the reaction force received from the luggage 1 to give a pressing force to attach the tag label 2 to the luggage 1.

Further, the elastic member 251 is made of a porous material (sponge) having a large number of bubbles.

Based on the above configuration, when there is an undulation on the surface to be attached of the luggage 1 to which the tag label 2 is attached, the elastic member 251 elastically deforms to contract the porous material (sponge), and the tag label 2 is attached to the luggage 1. Sufficient pressing force for sticking can be given.

The porous material (sponge) is made by foam-molding rubber.

Based on the above configuration, both elasticity and durability can be ensured by foam molding the rubber. The porous material (sponge) may be made of another synthetic resin.

Further, the suction pad 241 has a suction surface 241a that abuts and sucks the tag label 2, and the support portion 250 has a support surface 251a that abuts the tag label 2. Then, when the suction pad 241 sucks the tag label 2, the suction surface 241a moves from a position where the suction surface 241a protrudes from the support surface 251a toward the transport mechanism 210 side to a position where it extends at least in a straight line with the support surface 251a.

Based on the above configuration, since the suction surface 241a protrudes below the support surface 251a before the suction pad 241 sucks the tag label 2, the operation of the suction pad 241 sucking the tag label 2 is hindered by the support portion 250. Not done. Then, the suction pad 241 contracts due to the negative pressure for sucking the tag label 2, so that the suction pad 241a rises to a position where the suction surface 241a is at least substantially the same height as the support surface 251a. Therefore, the tag label 2 adsorbed on the suction surface 241a extends linearly by abutting on the support surface 251a, and then wrinkles are formed on the tag label 2 affixed to the luggage 1 (adhesive body). Can be prevented.

In addition, the transport mechanism 210 includes a transport conveyor 211 (conveyor unit) that transports the tag label 2, and a push-up 220 that pushes up the tag label 2 conveyed by the transport conveyor 211 from the transport conveyor 211.

Based on the above configuration, the tag label 2 conveyed by the transfer conveyor 211 is received by the sticking mechanism 240 in a state of being pushed up from the transfer conveyor 211 by the push-up portion 220. As a result, the adhesive layer 5e of the tag label 2 is not pressed against the conveyor 211. Therefore, the adhesive layer 5e of the tag label 2 is suppressed from being adhered to the conveyor 211, and the tag label 2 is smoothly delivered. Then, since the adhesive of the pressure-sensitive adhesive layer 5e is prevented from adhering to the transport conveyor 211, the state in which the transport conveyor 211 smoothly transports the tag label 2 is maintained.

Further, the suction pad 241 is provided at a position facing the push-up portion 220.

Based on the above configuration, the suction pad 241 sucks the tag label 2 so as to sandwich it with the push-up portion 220. As a result, in the sticking mechanism 240, the tag label 2 is surely sucked by the suction pad 241.

Further, the push-up portion 220 includes a blade 221 that makes linear contact with the tag label 2.

Based on the above configuration, the blade 221 linearly contacts the adhesive layer 5e of the tag label 2 and the contact area with respect to the adhesive layer 5e is reduced, so that the tag label 2 is adhered via the adhesive layer 5e. Is prevented. As a result, the sticking mechanism 240 smoothly receives the tag label 2.

The blade 221 is not limited to the above-described configuration, but has a tip portion in which a plurality of pin-shaped protrusions are lined up at intervals, and is configured to make point-like contact with the adhesive layer 5e of the tag label 2. May be good. In this case, since the contact area of the blade 221 with respect to the pressure-sensitive adhesive layer 5e is reduced, it is possible to effectively prevent the blade 221 from adhering to the pressure-sensitive adhesive layer 5e.

Further, the push-up portion 220 is arranged so that a plurality of blades 221 face the suction pad 241 via the tag label 2.

Since the tag label 2 is supported over the plurality of blades 221 based on the above configuration, it is possible to prevent bending or the like from occurring at a portion facing the suction pad 241. The suction pad 241 sucks the tag label 2 so as to sandwich the tag label 2 with the plurality of blades 221 to ensure that the tag label 2 is sucked.

Further, the tag label 2 has an adhesive layer 5e that is adhered to the luggage 1, and the suction pad 241 is arranged so as to adsorb the surface of the tag label 2 opposite to the adhesive layer 5e.

Based on the above configuration, when the tag label 2 is attached to the package 1, the suction pad 241 presses the surface of the tag label 2 opposite to the adhesive layer 5e. As a result, the adhesive layer 5e of the tag label 2 is pressed against the luggage 1 by the suction pad 241 to ensure that the label 2 is attached to the luggage 1.

Further, the sticking mechanism 240 is configured to receive the tag label 2 from the transport mechanism 210 by moving up and down above the transport mechanism 210, and to stick the tag label 2 to the luggage 1 by moving up and down above the luggage 1.

Based on the above configuration, the label affixing device 10 reliably receives the tag label 2 from the transport mechanism 210 and affixes the tag label 2 to the package 1.

Although the embodiments of the present invention have been described above, the above embodiments are only a part of the application examples of the present invention, and the technical scope of the present invention is limited to the specific configurations of the above embodiments. Absent.
