Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating apparatus for automatically laminating postcards and photographs using a tape having an adhesive layer such as glue, and in particular, the tape is wasted too much. The present invention relates to a bonding device that does not become a defect.

[0002]

2. Description of the Related Art FIG. 5 is a side view showing the structure of a device for automatically attaching a postcard and a photograph. The postcards stored in the hopper 10 are sent one by one by some rollers. On the other hand, the tape 12 having the glue layer is supplied from the tape supply side reel portion 14, and is passed between the tape bracket 16 and the transfer roller 18 together with the sent postcard. Therefore, the glue layer on the tape 12 is transferred to the postcard. The tape 20 to which the glue layer has been transferred is wound around the tape winding side reel portion 22. The postcard is further conveyed to the left in FIG. 5 and overlapped with the photograph from the hopper 24.
It is pressed by 6 and stuck together. The integrated postcard and photo are cut into a predetermined size by the cutter 28 and the slitter 30 and accumulated in the receiving portion 31.

FIG. 6 is a view showing a conventional structure of the tape supply side reel section 14. A shaft 36 is fixed to a housing 32 of the laminating device by a hexagonal nut 34, and a rotating portion 42 is attached to the shaft 36 via a torque limiter 38 and a bearing 40. Therefore, the rotating unit 42 does not rotate unless a torque larger than a predetermined value is applied. The rotating portion 42 holds the tape 12 having a glue layer. Therefore, tape 1
A certain amount of tension is required to pull out the tape 2, and the tape 12 is always tensioned so that slack does not occur. A stopper 44 is attached to the tip of the shaft 36 so that the reel of the tape 12 does not come off from the reel portion 14 on the tape supply side.

[0004]

When the paste layer is transferred and formed on the upper surface of the postcard by the laminating apparatus configured as described above, the postcards are successively sent from the hopper 10. Therefore, it is necessary to supply the tape 12 at a constant speed during the formation of the paste layer in order to keep the formation state constant, but until the next postcard is sent after the formation of the paste is completed. It is necessary to stop the tape 12. Therefore, when the tape 12 is stopped, inertia causes the rotating portion 42 to rotate excessively, causing the tape 12 to sag. Further, even if the glue layer is to be separated when the formation of the glue layer is completed, the glue layer often does not separate from the tape 12 well and is in a stringing state, so that the tape 12 is pulled and loosened. Cause.

In order to eliminate such slack of the tape 12, the tape winding side reel portion 22 has a length of 25 mm.
It was necessary to wind the tape 12 extra, and the tape 12 for this amount was wasted.

Therefore, an object of the present invention is to provide an actuator on the reel portion of the tape supply side to forcibly rewind the tape having the glue layer, thereby making it possible to remove the deflection of the tape and waste the tape. It is to provide a bonding device that does not require

[0007]

In order to achieve the above object, the invention according to the present application discloses a postcard supply means for supplying postcards one by one and a tape supply reel for holding a tape having an adhesive layer. Section and an adhesive layer forming means for forming a layer of adhesive on the postcard by pressing the tape supplied from the reel portion on the tape supply side to the surface of the postcard and transferring the layer of the adhesive on the tape, and the adhesive. Tape reel side to wind up the tape after the layer has been transferred, a photo feeding means for feeding one photo one by one onto the postcard on which the adhesive layer is formed, and the postcard and the above And a sticking means for sticking the two to each other by applying pressure to the photograph, and an actuator for applying tension to the tape to remove the slack of the tape is provided in the reel portion of the tape supply side. And it is characterized in that they are.

[0008]

In the present invention, an actuator is provided on the reel portion of the tape supply side, and the actuator applies tension to the tape having the glue layer to remove the slack of the tape. Therefore, the amount of the tape used can be suppressed to a necessary minimum, and the waste of the tape is reduced.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the same reference numerals are used for the same or corresponding parts in the drawings.

FIG. 1 is a side view showing the internal construction of a laminating apparatus constructed according to the present invention. The postcard is stored in the hopper 10, and the pick roller 46 is rotated while hitting the upper surface of the postcard, so that the postcard shown in FIG.
Is sent to the left in the direction of and is passed between the feed roller 48 and the retard roller 50. Here, the feed roller 48 arranged above the postcard is rotating in the right direction, that is, in the direction of sending the postcard to the left, and the retard roller 50 arranged below the postcard is rotating in the right direction, that is, the postcard. It is rotating in the direction of returning to. Therefore, when the pick roller 46 picks up two or more postcards at the same time, only the upper one is sent to the left and the remaining postcards are returned to the hopper 10.

One postcard sent to the left is the roller 5
It is further fed to the left by 2 and passed through the sensor 54 and between the tape bracket 16 and the transfer roller 18. Between the tape bracket 16 and the transfer roller 18, the tape 12 having a layer of adhesive (adhesive) attached to one surface is also passed, and the adhesive is attached to the surface on the side contacting the postcard. When the number of pulses applied to the drive motor reaches a predetermined value after the postcard passes between the sensors 54, a transfer roller 1 is activated by a solenoid (not shown).
8 rises, postcard and tape 12 tape bracket 1
6 and the transfer roller 18 so that the tape 12
The glue layer adhering to is transferred to the postcard, and the paste layer is formed on the postcard. The tape 12 having the glue layer is supplied from the tape supply side reel portion 14, and the tape 20 after the glue layer is transferred to the postcard is wound on the tape winding side reel portion 22.

The postcard on which the glue layer is formed is further provided with rollers 56, 58 and a conveyor belt 60 stretched between them.
Sent by. At this time, the postcard passes between the sensors 62, but at this time, picking of the photograph stored in the hopper 24 is started. The picking action for photographs is similar to the picking action for postcards. That is, as the pick roller 64 rotates while hitting the upper surface of the photograph, the photograph is sent out in the lower left direction in FIG. 1, and is passed between the feed roller 66 and the retard roller 68. Here, the feed roller 66 is rotating in the direction of feeding the photograph to the lower left, and the retard roller 68 is rotating in the direction of returning the photograph to the hopper 24. Therefore, when the pick roller 64 picks up two or more photographs at the same time, only the upper one is fed in the lower left direction and the remaining photographs are returned to the hopper 24. The photograph is further sent by the roller 70, and when it passes between the sensors 72, the photograph is stopped and put in a standby state. Then, when the postcard is sent by the conveyor belt 60 or the roller 74 and passes between the sensors 76, the feeding of the photograph is restarted, and the postcard and the photograph are passed between the rollers 26 in an overlapping state. Since pressure is applied between the rollers 26, the postcard and the photograph are attached to each other by glue.

The attached postcard and the photograph are further conveyed to the left in FIG. 1, and after a certain period of time has passed after passing between the sensors 78, the tip of the cutter 28 has a predetermined length. For example, only 1.5 mm is cut. The postcard and the photograph are further sent by the roller 80 and passed through the slitter 30, and both side portions are cut so that the left and right lengths (the lengths of the short sides of the postcard) become predetermined values. The postcard and the photograph are sent by the roller 86 after passing between the sensors 82 and 84, but after a certain time has passed after the tip portion passed between the sensors 82 and 84, the trailing end portion is the cutter 28. Cut by. Therefore, the vertical length (long side length) of the postcard and the photograph is set to a predetermined length. The length at which the rear end is cut is about 1.5 mm for postcards and about 2.5 mm for photographs. In this way, the postcard and the photograph, which are cut into the predetermined size by cutting the front end portion, the rear end portion, and the both side portions, are accumulated in the receiving portion (not shown) attached to the left end of the transport path.

Next, the structure of the tape supply side reel portion 14 will be described with reference to FIG. A fixing portion 90 having a hollow portion 88 is attached to the housing 32 of the laminating apparatus. The hollow portion 88 has two bearings 92, 94.
The shaft 96 is rotatably passed through. Further, the bearing 98 and the shaft 9 attached to the fixed portion 90.
The rotary unit 102 is rotatably mounted via the bearing 100 mounted on the shaft 6. A torque limiter 104 is provided between the shaft 96 and the rotating unit 102. The shaft 96 is driven by the motor 110 via the speed reducer 106 and the bevel gear 108. The rotating unit 102 is attached to the tape 1 by using such a mechanism.
The bending of the tape 12 can be removed by rotating the tape 2 in a direction in which tension is applied (clockwise in FIG. 1). Further, since the torque limiter 104 is interposed,
Excessive tension does not act on the tape 12 to break the tape 12.

Further, since the paste layer formed on the tape 12 is successfully transferred to the postcard by this mechanism, the cut surface of the paste layer becomes straight and the tip of the paste layer on the postcard is made straight. The position can be controlled accurately. Therefore, it becomes possible to form the glue layer from a little distance (for example, about 1 mm) from the end of the postcard. If you create a layer of glue from the end of the postcard,
The postcard may peel off when the tape 12 is pulled in order to transfer the paste layer from the tape 12 to the postcard, but by forming the paste layer slightly away from the end of the postcard, It is possible to prevent such postcard peeling.

Next, FIG. 3 is a view showing an example of the cutter 28. The cutter 28 is composed of one moving blade 112 that is attached at a slight inclination and moves up and down, and a fixed blade 114, and the front end and the rear end of a postcard sent as shown in FIG. 1 are the same. It is cut with a blade. FIG. 3 (a) is a diagram showing a state in which the tip portion is cut, and a postcard 116 and a photograph 118 sent as indicated by an arrow A1 are placed between the moving blade 112 and the fixed blade 114 which are descending. Is cut in. Figure 3 (b) shows the state after cutting,
Due to the inclination of the movable blade 112, the cut edge 120 has a raised portion 122. This raised part 12
2 is possible because there is a layer of glue between the postcard 116 and the photo 118. On the other hand, FIG. 3 (c) is a view showing a state in which the rear end portion is cut. In this case, there is no raised portion on the scrap 124, and the postcard 1
16 and the photograph 118 have a raised portion 126. Therefore, there is a raised portion 126 in the finished product, and the product, that is, the postcard 1
16 and the photograph 118 are pasted, but the quality is low.

FIG. 4A is a view showing another example of the cutter 28. In this case, the movable blade 128 and the fixed blade 130
Both are composed of two blades. FIGS. 4B and 4C show a state in which the tip of the postcard 116 and the photograph 118 are cut by using the cutter 28. Moving blade 12
Since the inclination of 8 is oriented so that the raised portion is formed toward the cut edge 132, the raised portion cannot be formed on the product. On the other hand, when cutting the rear end portion of the postcard 116 and the photograph 118, it becomes as shown in FIGS. 4 (d) and 4 (e). The blade used in this case is a blade different from the blade used when cutting the tip portion, and the inclination of this blade is oriented so that a raised portion is formed toward the cutting edge 134. , Even in this case, there is no bulge on the product. In this way, since the raised portion is not formed anywhere in the product, its quality is high.

The hopper 10 and the rollers 46, 48,
50 and 52 form a postcard supply unit, the tape bracket 16 and the transfer roller 18 form an adhesive layer forming unit, and the hopper 24 and the rollers 64, 66 and 6 are formed.
8, 70 constitutes a photo supplying means, and the roller 26
Is a sticking unit, and the motor 110 is an actuator.
