Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a labeling device for stacking flat packages.

(Conventional technology) Currently, labeling operations at paper mills involve manually gluing a pile of flat-packed items and then manually pasting labels one by one.
There were problems in terms of labor saving and efficiency. Taking this problem into consideration, after the adsorption tool adsorbs the label in the supply section, the adsorption tool is reversed to apply glue etc. to the label and face the laminate, and then pressed against the laminate by a cylinder. The applicant has proposed in Japanese Unexamined Patent Application Publication No. 13633/1983 a device to which a label can be attached. In this method, one label is sucked and pasted by reciprocating and reversing operations of one suction tool.

(Problem to be solved by the invention) As mentioned above, the apparatus disclosed in the above publication is capable of automatically attaching labels to laminates, but since it operates by reciprocating and reversing one suction part, the first The label was adsorbed by reversing the first one, and the label was attached by the second reversing, so two reversing operations were required for one label application. For this reason, further improvements were desired in terms of efficiency.

Therefore, the present invention was developed in consideration of this situation, and the purpose is to provide a label affixing device for stacking flat packages that can affix objects to be affixed without requiring the suction unit to be reversed twice. shall be.

A female screw 17A provided on the receiving portion 3 is screwed into the male screw 17. An intermittent drive servo motor 19 is connected to this male screw 17 via a gear 18. At the upper end of the frame body 12, an arm 20 protrudes toward the laminate 1. An air cylinder 21 is vertically installed on the arm 20, and this piston 22 descends to support the upper end surface of the laminate 1.

A frame body 23 is provided in the receiving portion 3 so as to be movable back and forth toward the laminate 1 via a rail 24, and an electromagnetic drive unit, which is the pressing mechanism 7, is provided on the frame body 23. A rotating shaft 26, which is a rotating part, is supported at the end of the frame 23 on the side of the laminate 1 in parallel with the surface of the laminate 1.
On both sides of the rotating shaft 26, a pair of suction tools 6, 6A are arranged horizontally in opposite directions at intervals, and a plurality of guide rods 27 protrude from the suction tools 6, 6A. The guide rods 27 are inserted into the rotating shaft 26 and locked by a stopper 28, and a spring 29 is wound around each guide rod 27. Furthermore, an air passage 30 is formed that communicates with the rotating shaft 26, the guide rod 27, and the suction tools 6, 6A, respectively, and an air suction and ejection device using a compressor, electromagnetic valve, etc. (not shown) is connected to this air passage 30. ing. Further, a drive device 32 that rotates intermittently every 180 degrees is connected to the rotating shaft 26 via a gear 31, thus forming a label suction device.

3 is connected to an electromagnetic drive section 34, and the case 33 is arranged so as to be movable back and forth toward the label suction tools 6, 6A via rails 35. Also, case 33
A push plate 36 for constantly pressing the label 8 toward the suction tools 6, 6A is arranged inside, and is biased with elastic force by a spring 37. A leaf spring 38 is provided at the end of the case 33 on the suction tools 6, 6A side to restrict the most advanced label 8 to a predetermined position.

A gluing roller 39 is rotatably disposed on the receiving portion 3 at a position where the suction tools 6, 6A come into contact with each other when they rotate. A rotary drive device 42 is connected to the glue roller 41 . The gluing roller 39 is formed with a plurality of grooves 43, into which a plurality of bars 44 that are in contact with the label 8 are engaged, and a spring 45 that always applies an upward rotational force is connected to the bar 44. It is locked by a stopper (not shown).

Next, the operation of the above device will be explained. Conveying device 14
When the laminate 1 is transferred to a predetermined position and stopped, the air cylinder 21 is operated, the piston 22 is lowered, and its tip supports the upper end surface of the laminate 1, and as shown in FIG. 6A, the electromagnetic drive unit 34, the case 33 moves forward, and the frontmost label 9 is attracted to the suction tool 6A by the suction force of the air suction and ejection device. Thereafter, when the case 33 retreats, the adsorbed label 8 is released from the leaf spring 38. Next, the 6th
As shown in Figure B, the rotation shaft 2 is rotated by the operation of the drive device 32.
6 is rotated by 180 degrees, the suction tool 6A is reversed and placed in a position facing the stacked product 1, and at the same time, the suction tool 6 on the stacked product 1 side is located on the label case 33 side. In this case, the suction tool 6A engages with the gluing roller 41 during movement and comes into contact with the gluing roller 39 that has absorbed the glue, and the bar 4
4 is slid on the surface of the gluing roller 39 while being pressed downward against the elastic force of the spring 45, and the label 8 is coated with glue and becomes ready for adhesion. Then the 6th
As shown in FIG. C, the adsorption tool 6A is pressed against the laminate 1 through the frame 23 by the electromagnetic drive unit 7 while compressing the spring 29, and the label 8 is pasted. Next, the servo motor 19 operates to move the receiving part 3 along the predetermined pitch rail 16, and then, in the same way as the above operation, the label case 33 advances to attract the label to the suction tool 6, and the same operation is repeated.

In this way, in the above embodiment, the suction tool 6,
One 180° rotation of 6A enables pasting and suction operation with the label 9, so one 360° rotation of the suction tools 6 and 6A enables label pasting twice, and therefore one time. The operating time of the label pasting mechanism is halved, allowing efficient automatic pasting work.

Note that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.
For example, a cylinder or the like may be used instead of the electromagnetic drive device, a rotary encoder and a motor may be used instead of the servo motor, an air motor may be used for intermittent rotation, etc., and the actuating device may be selected as appropriate. In addition, as a means for intermittently moving the receiver, a comparator that can be adjusted by an appropriate means may be connected to the rotary encoder to measure and adjust the thickness of the laminate in advance, or an appropriate sensor may be used to sense the location where the label is attached to the package. Alternatively, it may be controlled by a computer and may be selected as appropriate. Further, as shown in FIGS. 3 and 4, the stamp 46 may be pressed at the same time as labeling.
