FIG. 1 is a schematic perspective view showing an example of an automatic product card sticking apparatus according to the present invention, in which a supporting column 4 is erected on a positioning stage 3 which is moved back and forth by a motor 2 along a linear guide 1. A bar code labeler 6 for outputting a bar code label 5 as a product card is attached to the upper end portion of 4.

The bar code labeler 6 prints and outputs information about products as a bar code and characters on the bar code label 5. The bar code label 5 used here is as shown in FIG. An adhesive tape 7 having a narrow width is attached to the central portion of the back surface along the longitudinal direction, and the adhesive tape 7 is attached to the long release paper 8 wound in a roll in a cut state. The bar code labeler 6 holds the product card laminated paper roll 9 formed by attaching the bar code label 5 to the release paper 8 and feeds the laminated paper to print the bar code label 5 for output. Has become.

Specifically, as shown in FIG. 3, the barcode labeler 6 has a paper feed shaft 10 for holding a laminate paper roll 9 and a printer 11 built therein, and is fed from the laminate paper roll 9. The laminated paper is sent to the printer 11 via the guide rolls 12 and a pair of drive rolls 13 provided on the discharge side of the printer 11
Is designed to give tension to the laminated paper. The printer 11 is a well-known printer that has been generally used for printing barcodes.

On the front side (right side in the figure) of the drive roll 13, a knife edge 14 is arranged downward, and above the drive roll 13, tension is applied to the release paper 8 or the release paper 8 is loosened in the opposite direction. Thus, a pair of control rolls 15 that are normally and reversely rotated are arranged. Furthermore, a winding shaft 16 for winding the release paper 8 that has passed through the control roll 15 is provided. That is, the laminated paper sent out from the drive roll 13 is wound around the knife edge 14 from the lower side, and is wound up by the winding shaft 16 via the control roll 15. In the process, the bar code label 5 is attached at the knife edge 14. It is designed to be peeled off from the release paper 8.

Below the drive roll 13, there is provided a suction head 17 which sucks the hacord label 5 peeled from the release paper 8 and moves back and forth. The suction head 17 is moved back and forth by an actuator such as an air cylinder (not shown).
Is sucked by vacuum suction.

The following mechanism is provided in order to securely attach the bar code label 5 to the band 18 fixing the product. That is, below the barcode labeler 6, a centering block 19 is provided integrally with the barcode labeler 6. The centering block 19 has a concave groove 20 on the front side along the vertical direction with the center line in the horizontal direction coinciding with the suction head 17, and the left and right inner wall surfaces of the concave groove 20 are formed by the band 18. Is formed in a taper shape for guiding to the center position. The centering block 19 and the bar code labeler 6 can freely move in the left-right direction within a predetermined range, or can freely move in the left-right direction along with the support column 4 in a predetermined range.

On the slightly upper side of the centering block 19, there is provided an insertion edge 21 which can be moved in the left-right direction and in the front-back direction perpendicular thereto. The insertion edge 21 is for pulling the band 18 toward the barcode labeler 6 side, and is formed in an elongated plate shape. A mechanism for driving the insertion edge 21 will be described. Below the bar code labeler 6, an advancing / retreating cylinder 22 that operates in the front-rear direction is held by a column 4, and the rod of the advancing / retreating cylinder 22 is held. An insertion / withdrawal cylinder 23 that moves in the left-right direction is attached to the tip of the insertion edge 2
1 is operated in the left-right direction by the insertion / drawing cylinder 23.

Further, the centering block 19 and the suction head 17 are located slightly above the insertion edge 21.
And a vacuum pad 24 whose center positions in the left-right direction are aligned with each other. The vacuum pad 24 is for securing a space for inserting the insertion edge 21 by sucking the band 18 and pulling it toward the barcode labeler 6 side, and is held so as to move back and forth with respect to the band 18. .

On the upper side of the vacuum pad 24, there are arranged a pressure roll 25 and a guide roll 26 which move forward and backward in the left-right direction and are driven in the vertical direction. That is, an elevating cylinder 27 is attached to the column 4 in the up-down direction.
A roll insertion cylinder 28 that moves in the left-right direction is attached to the movable portion of 7. This roll insertion cylinder 2
A back-and-forth moving cylinder 29 is attached to the movable part of 8, and the pressure-bonding roll 25 and the guide roll 26 are attached to the moving part of the back-and-forth moving cylinder 29 via a bracket 30.

The pressure bonding roll 25 presses the band 18 against the adhesive tape 7 provided on the back surface of the bar code label 5, and is constituted by, for example, a rubber roll. The guide roll 26 is for guiding the band 18 so as not to shift in the left-right direction, is provided above the pressure bonding roll 25, and is an annular groove that fits the band 18 in the central portion in the axial direction. 26a is formed.

The above-mentioned device is a band (polypropylene band: a band for fixing products (for example, a can body of a two-piece can or a three-piece can) stacked on a pallet.
A device for sticking the barcode label 5 to the PP band 18 and is arranged at the side of the pallet transport line 31 as shown in FIG. 4, for example. That is, the products 33 are stacked on the pallet 32 in multiple stages with the chip boards 34 sandwiched between them, and the top plate 35 is arranged at the upper end portion thereof, and the whole of the two or three PP bands 1 are provided.
It is fixed by 8. The product card sticking device described above is arranged on the side of the chain conveyor 36 that conveys the pallet 32. Since the position where the product card (bar code label) 5 is attached is determined by the specifications of the delivery destination, the height of the bar code labeler 6 can be adjusted at the time of installation.

Next, the operation of the above-mentioned device will be described. When the information about the product is given to the barcode labeler 6 by, for example, a personal computer (not shown), the printer 11 prints the barcode label 5 according to the information. Along with or after printing the barcode label 5, the drive roll 13 operates to feed the laminated paper from the roll 9. In that case, the control roll 15 that applies tension to the release paper 8 is the drive roll 13.
At the same time, the peeling paper 8 is driven to rotate in the normal direction, and as a result, the release paper 8 is bent by the knife edge 14 and can be handled as it is, so that the barcode label 5 is peeled from the release paper 8. Immediately before the barcode label 5 is completely peeled off, the control roll 15 is reversely driven as shown in FIG. 3A, and the printed barcode label 5 is printed on the front side of the suction head 17 together with the release paper 8. Hang down.

In this state, the suction head 17 is retracted, and the suction head 17 vacuum-sucks the bar code label 5 hanging down on the front side thereof. In that state, the control roll 15 and the take-up shaft 16 rotate forward in the direction of the arrow shown in FIG. 3B, and as a result, the release paper 8 is sucked by the suction head 17.
It is peeled from the back surface of the barcode label 5 adsorbed on. As shown in FIG. 2, since the barcode labels 5 are attached to the release paper 8 one by one, the release paper 8 is wound around the take-up shaft 16 as described above, so that the suction head 17 sucks it. Only the bar code label 5 that is printed will be peeled off from the release paper 8. The suction head 17 that has thus sucked the barcode label 5 moves forward and stands by.

On the other hand, the product 33 that has been piled up on the pallet 32 and finished banding is the chain conveyor 36.
Is progressing toward the above-mentioned product card pasting device, and when reaching a predetermined position on the front side thereof, the chain conveyor 36 is decelerated and the band 18 is positioned at a position where the band 18 coincides with the front surface of the suction head 17 described above. 36 is stopped and the pallet 32 is positioned. When the pallet 32 stops, the vacuum pad 24
Moves forward to adsorb the band 18 located on the front side thereof, and the vacuum pad 24 retracts to separate the band 18 from the product by a predetermined size. Around this time, the forward / backward moving cylinder 22 operates to move the insertion / withdrawing cylinder 23 forward toward the product 33 side, and the vacuum pad 24 bends the hand 17 toward the barcode labeler 6 side as described above. No, the band 18 and product 33
The insertion edge 21 is inserted by the insertion / withdrawing cylinder 23 between them, and the forward / backward moving cylinder 22 moves backward in this state, whereby the band 18 is further bent in the direction away from the product 33.

On the other hand, the lifting cylinder 27 stands by at the lowered position, and the pressure bonding roll 25 and the guide roll 26 are held at the lower limit position. When the band 18 is bent by the insertion edge 21 as described above, the pressure roll 25 and the guide roll 26 are inserted by the cylinder 28 between the band 18 and the product 33. Then, the forward / backward-moving cylinder 29 having the rolls 25 and 26 attached thereto retracts to draw the band 18 toward the suction head 17. In this state, the raising and lowering cylinder 27 moves upward, so that the pressure bonding roll 25 and the guide roll 2
6 moves upward on the front surface side of the suction head 17. In that case, since the band 18 is fitted in the annular groove 26 a of the guide roll 26, the suction head 17 and the band 18 are
The positions in the left and right direction are held, and in this state, the pressure bonding roll 25 positioned below the guide roll 26 moves upward so as to press the band 18 against the front surface of the suction head 17 waiting for forward movement. That is, the band 18 and the barcode label 5 are sandwiched between the suction head 17 and the pressure roll 25, and as a result, the adhesive tape 7 having the barcode label 5 attached thereto is firmly attached to the band 18. The suction of the bar code label 5 by the suction head 17 is released at the time when the pressure bonding roll 25 moves up to the upper limit position, that is, above the upper end of the suction head 17. Then, the elevating cylinder 27 descends and the pressure bonding roll 25 and the guide roll 26 are returned to the original lower limit position.

Then, the roll-advancing drive cylinder 28 moves slightly forward so that the pressure-bonding roll 25 and the guide roll 26 are moved.
Is separated from the band 18, and in that state, the insertion / withdrawing cylinder 27 moves backward to move the rolls 25 and 26 into the band 18.
And the product 33. Further insert edge 21
Is pulled back to its original position by the insertion / drawing cylinder 23, and as a result, the band 18 returns to its original state and a series of operations is completed.

Therefore, according to the above apparatus, a series of operations such as printing a bar code label, outputting the bar code label, peeling from a release paper, and sticking to a band can be automatically performed. Further, when attaching the barcode label 5 to the band 18, since the band 18 is kept in a state of being separated from the product, the load when attaching the barcode label does not act on the product, and therefore the product is not damaged. It can be reliably and reliably prevented.

FIG. 5 is a diagram schematically showing another print peeling mechanism which can be adopted in the present invention. Above the suction head 17 which sucks the bar code label 5 and advances it,
A knife edge 40 is provided with its tip end facing substantially vertically downward, and a plurality of guide rolls 41 for guiding the laminated paper from the laminated paper roll 9 on the paper feed shaft 10 to the knife edge 40 are provided. There is. In the middle of the paper feeding process in which the guide roll 41 is arranged, a brake 42 is arranged to sandwich the laminated paper and prevent its movement.

A print head 43 for printing on the bar code label 5 attached to the release paper 8 is arranged at a position above the suction head 17 where the laminated paper is guided substantially vertically downward by the guide roll 41. Has been done. The ink ribbon 44 is supplied between the print head 43 and the barcode label 5. Further, a plurality of guide rolls 46 for guiding the release paper 8 are arranged on the take-up shaft 45 on the side opposite to the print head 43 with the knife edge 40 interposed therebetween, and the guide rolls 46 are arranged in the middle of the positions. A brake 47 is arranged to sandwich the release paper 8 and prevent its movement.

Therefore, in the mechanism shown in FIG. 5, the roll 9
The laminated paper fed from the sheet passes through the front side of the print head 43, and at that time, the barcode label 5 is subjected to predetermined printing such as a barcode. Further, since the laminated paper is folded around the knife edge 40 and bent at an acute angle and can be handled in that state, the bar code label 5 on which printing has been completed is peeled from the release paper 8.
It hangs down to the front side of the suction head 17 in the retracted position.
The bar code label 5 is adsorbed by the adsorption head 17 when it is completely peeled off from the release paper 8. After that, the adsorption head 17 advances toward the belt 18 so that the bar code label 5 is removed. Belt 18
Pasted on.

Although the position of the bar code labeler 6 is adjusted at the time of installation in the above embodiment, a sensor for detecting the position of the band is provided and the bar code labeler 6 is automatically adjusted to the relative position to the band. When such a servo mechanism is provided, the above-mentioned centering block becomes unnecessary, and the frequency of sticking errors can be suppressed to a very low level. Further, in the above embodiment, the pressure-bonding roll and the guide roll are provided on the lower side of the suction head to drive them upward, but in the present invention, conversely, the pressure-bonding roll is lowered from the upper side. Alternatively, the product card and the band may be crimped.

[0029]

As described above, according to the present invention,
When the printing is completed and the product card with the adhesive on the back side is peeled off from the release paper and the back side is held toward the front, the suction head and the mechanism that pulls the band to which the product card is attached to the suction head side Since a mechanism that presses the band pulled toward the head side against the front of the suction head is provided, it is possible to automate the attachment of the product card to the band and improve the work efficiency, and also to reduce the load when attaching the product card. Since it does not affect the product fixed by the band, it is possible to prevent the product from being damaged or the load collapsed. Further, since the product card is supplied to the front surface of the suction head in a state of being attached to the release paper, there is no possibility that the product card is misaligned, and it is possible to prevent the product card from being stuck wrongly.
