Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape sticking apparatus for a photo sticking machine for sticking a photograph on a card such as a postcard.

[0002]

2. Description of the Related Art In addition to heat-sensitive adhesives, liquid adhesives and the like, double-sided adhesive tapes and the like can be used as adhesives used for attaching photographs to cards such as postcards. Various pasting machines have been proposed and put into practical use.

[0003]

In a photo pasting machine using a heat-sensitive adhesive, the adhesive is solidified in ordinary handling, and the handling of the adhesive itself is easier than in the adhesive type or liquid type. However, since the device is bonded by heating and pressure bonding, the device configuration becomes large, and it has been difficult to reduce the size and cost. In addition, since the adhesive layer is hardened after bonding, there is a problem that the stiffness of the card on which the photo is pasted becomes strong. On the other hand, a sticking machine using an adhesive type or liquid type adhesive has the advantage of eliminating the drawbacks such as increased stiffness of the card. Due to its tackiness, its handling becomes difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is intended to provide a photo pasting machine which can easily handle a large amount of photographs with a simple structure by easily handling an adhesive. An object is to provide an adhesive tape attaching device.

[0005]

According to a first aspect of the present invention, there is provided an adhesive tape sticking apparatus for a photo sticking machine, wherein a double-sided tape consisting of a peeling tape and an adhesive tape is used to copy a photograph and a card. In the adhesive tape application device of a photo affixing machine for applying the card by the affixing and transporting unit, the card storage unit for stacking and storing the cards and the adhesive surface of the double-sided tape are pressed against the leading end of the card in the card storage unit, and the card is pressed. And a double-sided tape pressure-feeding feeding member for feeding the pressure-sensitive adhesive to the attaching section. Thus, by continuously driving the double-sided tape pressure-feeding member, a card such as a postcard can be continuously bonded to the double-sided tape with almost no gap. Therefore, a large number of cards are continuously adhered to the adhesive tape with a simple configuration. This allows the adhesive tape to be attached to the postcard at an initial stage, thereby facilitating the handling of the adhesive tape. In addition, it is preferable that the double-sided tape pressure-feeding member is constituted by a sheet feeding roller, and in this case, the structure is further simplified.

According to a third aspect of the present invention, there is provided an adhesive tape sticking apparatus for a photo sticking machine, wherein a peeling tape guide member for peeling off a peeling tape from the double-sided tape to which the card is adhered, and a card feeding direction with respect to the peeling tape guide member. And a pressing roller provided in contact with the adhesive tape and pressing the adhesive tape toward the card. Thereby, the release tape can be reliably peeled off from the double-sided tape.
Further, the adhesive roller and the release tape attached to the card can be reliably separated by the pressing roller. Therefore, it is possible to prevent the adhesive tape from peeling off from the leading end of the first card and the leading end peeling adhering to the peeling tape side. In addition, it is preferable to provide an urging means for urging the postcard toward the double-sided tape pressure-feeding member.

In the adhesive tape sticking apparatus of the photo sticking machine according to the present invention, the card feeding speed of the sticking / conveying section is higher than the card feeding speed of the double-sided tape pressure-feeding member, and the adhesive tape between the cards is cut off. . Thus, there is no need to separately provide an adhesive tape cutting means, and the configuration is simplified. Further, since the adhesive tape is merely cut between the cards, a positioning mechanism or the like is not required. Also,
In the adhesive tape sticking device of the photo sticking machine according to claim 6,
The feeding of the card to the sticking / conveying unit is detected, and based on this detection signal, the card feeding of the double-sided tape pressure-feeding member is temporarily stopped, and the adhesive tape between the cards is cut off. Thereby, the adhesive tape can be more reliably separated.
Incidentally, by setting the separation position of the adhesive tape on the downstream side in the card feeding direction with respect to the pressing roller,
The end of the postcard from which the adhesive tape has been separated does not flutter, and can be sent smoothly.

[0008]

FIG. 1 is a longitudinal sectional view of a photo pasting machine embodying the present invention. In the photo pasting machine 10, a postcard storage unit 12, a mounting shaft 14 for a double-sided tape roll 13, a winding shaft 16 for a release tape 23, a postcard pasting unit 17, a photo storage unit 18, and a photo pasting unit 19 are mounted on a frame 11. It is configured.

The frame 11 is formed in a box shape by fixing a pair of side plates 20 with a bottom plate 21, a stay 22, and the like. On the upper left side of the frame 11, a mounting shaft 14 of the double-sided tape roll 13 is rotatably mounted.
A take-up shaft 16 for a release tape 23 is rotatably attached to the upper center of the frame 11. These shafts 14 and 16 are made detachable from the frame 11. Then, in a state where the roll mounting shaft 14 is removed,
, A winding core 24 of the double-sided tape roll 13 is mounted, and an empty winding core 24 is mounted on the tape winding shaft 16.

The double-sided tape roll 13 includes a double-sided tape 15
Is wound around a winding core 24. As shown in FIG. 2, the double-sided tape 15 is configured by adhering an adhesive tape 25 to a release tape 23 made of release paper.

As shown in FIG. 3, the shafts 14 and 16 are linked by an interlocking chain 26 and sprockets 27 and 28. The sprocket 27 mounted on the roll mounting shaft 14 is opposed to the sprocket 28 on the winding shaft 16 side.
Has a reduced diameter so that there is a difference in the interlocking speed. Further, when the double-sided tape 15 is pulled out by the postcard attaching portion 17 as described later, the double-sided tape roll 13 is pulled out by this drawing.
Rotates, and the roll mounting shaft 14 rotates accordingly. This rotation is transmitted to the winding shaft 16 by the interlocking chain 26 and the sprockets 27 and 28.

At this time, the diameter of the double-sided tape roll 13 is the largest at the initial stage of the installation, and the winding core 24 on the winding side is the smallest. Due to the difference in the winding diameter, the peeling tape 23 will be loosened in the initial stage of the winding simply by interlocking, but in the present embodiment, the speed difference is provided by changing the number of teeth of each sprocket 27, 28. Therefore, even at the start of the operation, the release tape 23 does not loosen. The winding shaft 16 and the winding core 24 are friction-coupled, and the winding core 24 is rotated by frictional resistance. Therefore, as shown by the two-dot chain line in FIG. 1, when the peeling tape 23 is wound and its diameter is increased, the tape is appropriately slipped, and no excessive force is applied to the mechanism.

As shown in FIG. 1, the postcard storage unit 12
It is arranged on the left side of the frame 11. As shown in FIG. 4, the postcard storage unit 12 includes a postcard placement plate 30, a guide member 31, a tip stop plate 32, a holding plate 33, and a coil spring 3.
4 is provided. The mounting plate 30 is attached to the frame 11 horizontally and vertically by a guide member 31. The coil spring 34 is disposed between the mounting plate 30 and the bottom plate 21 and urges the postcard mounting plate 30 upward. The postcard mounting plate 30 has a maximum of 50 in this embodiment.
Although the postcards 35 can be stacked and stored, the number of storages may be changed as appropriate.

The pressing plate 33 is horizontally fixed to the frame 11 at a position facing the postcard mounting plate 30, and presses the postcard 35 on the mounting plate 30. This holding plate 33
Is shorter than the mounting plate 30, and the pressing plate rear end 3
The leading end 35a of the postcard 35 is exposed from 3a. Further, the rear end 33a of the holding plate is notched obliquely so that it does not hit the sheet feeding roller 40 described later.

As shown in FIG. 5, a gap G1 between the upper end surface 32a of the distal end stop plate 32 and the lower surface 33b of the holding plate 33 is provided.
Is set to allow the passage of one postcard. Thus, only the uppermost postcard 35 on the mounting plate 30 is allowed to pass, and the lower postcard 35 is restricted from passing therethrough.

As shown in FIG. 4, the postcard attaching section 17
Affixing paper feed roller 40, an adhesive roller pair 41, a peeling guide plate 42, a peeling tape feed roller pair 43, a pressing roller (hereinafter simply referred to as a postcard pressing roller) 44 at the tip of the first postcard, and a postcard feeding roller And a pair 45.

As shown in FIG.
Is disposed between the holding plate 33 and the end stop plate 32 so as to contact the uppermost postcard 35. The double-sided tape 15 is wrapped around the sticking sheet feeding roller 40. This wrapping is performed such that the peeling tape 23 comes into contact with the affixing paper feed roller 40 and the adhesive tape 25 is on the outside. Therefore, the tip 3 of the uppermost postcard 35
The adhesive tape 25 comes into contact with the adhesive tape 5a.
Are adhered. This adhesive tape 25
Is adhered to the entire surface of the postcard 35 by the movement of the postcard 35 due to the rotation of the sticking paper feed roller 40.

The bonding roller pair 41 includes a pressing roller 41a.
And the drive roller 41b. The adhesive tape 25 is securely attached to the postcard 35 by nipping and transporting the postcard 35 to which the double-sided tape 15 is attached.

As shown in FIG.
c, the lower roller shaft 41c of the adhesive roller pair 41, the postcard pressing roller shaft 44c, the upper roller shaft 45c of the postcard feed roller pair 45, and the upper roller shaft 43c of the peeling tape feed roller pair 43 via the sprocket 46 and the chain 47. Then, it is rotationally driven by a postcard attaching motor 48. In the drawing, reference numeral 49a indicates a guide roller, and reference numeral 49 indicates a tension sprocket. By changing the fixing position of the sprocket 49, the tension of the chain 47 is adjusted.

As shown in FIG. 4, the peeling guide plate 42
Release tape 2 from double-sided tape 15 attached to postcard 35
3 is made of Teflon resin. As shown in FIG. 6, the distal end portion 42 of the peeling guide plate 42
a is formed at an acute angle of 30 degrees, and
Is rounded. The peeling guide plate 42 ensures that the peeling tape 23 is peeled off during continuous bonding. The tip angle of the peeling guide plate 42 is 30.
Not limited to the degree, it may be changed as appropriate. The peeling tape 23 peeled off by the peeling guide plate 42 is fed by a peeling tape feed roller pair 43 and wound around the winding core 24. FIG. 6 shows that the double-sided tape 15 is set, and
In this case, the remaining adhesive tape 25 on the front end side is removed together with the peeling tape 23 by the peeling tape feed roller pair 43 and the core 2.
4

When the peeling tape 23 is peeled off from the first postcard 35 in the bonding process, the postcard pressing roller 44 presses the adhesive tape 25 so as not to be peeled off. As shown by the two-dot chain line in FIG. 6, the first postcard 35 of the work start is a postcard pressing roller 44.
Otherwise, the postcard tip 35a will also be pulled toward the feed direction side of the release tape 23. Therefore, the postcard tip 35a comes out of the transport path 36, and this causes postcard jamming. Also, release tape 2
At the start of the peeling of No. 3, a part of the adhesive tape 25 may be peeled off from the postcard tip 35a.

On the other hand, in the present embodiment, the post-pressing roller 44 is disposed in the direction in which the leading end 42a of the peeling guide plate 42 extends. Then, the pressing roller 44 rotates so as to direct the leading end 35 a of the postcard toward the transport path 36. Thereby, as shown by a solid line, the postcard tip 35
a is surely returned to the transport path 36. Therefore, clogging of the postcard 35 does not occur. Also, the postcard holding roller 44 uses the adhesive tape 25 as the release tape 23.
The tip of the adhesive tape 25 is pressed against the postcard 35 so that the adhesive tape 25 is not peeled off. As a result, the adhesive tape 25 at the postcard tip 35a does not peel off.

The transport path 3 of such a postcard tip 35a
6 and the process of preventing the adhesive tape 25 from peeling off the postcard 35 are effective when the first postcard, which is the first postcard, is passed. That is, as shown in FIG. 7, in the second and subsequent postcards 35, since the adhesive tape 25 is continuous with the previous postcard 35, the postcard tip 35 a is conveyed due to the influence of the peeling of the release tape 23. Road 3
You won't get out of 6.

As shown in FIG. 4, the peeling tape feed roller pair 43 nips and feeds the peeling tape 23, and includes a driving roller 43a and a pressing roller 43b. This release tape 23 is wound around a winding core 24. The postcard feed roller pair 45 nips the postcard 35 to which the adhesive tape 25 is adhered, and feeds the nip toward the photo sticking section 19. The drive roller 45 a and the pressing roller 4
5b.

The photo storage section 18 is arranged on the right side of the frame 11. As shown in FIG. 9, the photo storage unit 18
An inclined guide plate 50, a holding plate 51, a guide member 52, a tip stop plate 53, and a coil spring 54 are provided. Up to 50 photos 55 are inserted upright in the photo storage unit 18. The holding plate 51 is movably attached along the inclined guide plate 50 by a guide member 52. The pressing plate 51 is urged toward the distal end locking plate 53 by the coil spring 54. Thus, the photograph 55 is pressed by the end stop plate 53 by the pressing plate 51. Between the lower end of the distal end stop plate 53 and the lower end of the locking guide plate 50,
A gap is formed, and a photo feed roller 60 described later is disposed in the gap.

The photo sticking section 19 includes a photo feed roller 60
, A first bonding roller pair 61, a second bonding roller pair 62, and a postcard guide 63. The photo feed roller 60 contacts the outermost photo 55 and feeds it to the bonding roller pair 61.

As shown in FIG. 3, the photo feed roller shaft 60
c, Upper roller shaft 61 of first bonding roller pair 61
c, each roller shaft 62c of the second bonding roller pair 62,
62d is a sprocket 64a, 64b and a chain 6
5, and is rotated by a photo feed motor 66. Reference numeral 67 in the figure denotes a tension sprocket, and the tension of the chain 65 is adjusted by changing the fixing position of the sprocket 67.

As shown in FIG. 9, the feed speed V2 of the first bonding roller pair 61 is the same as the feed speed V1 of the postcard attaching portion 17. Thereby, the delivery of the postcard 35 is performed smoothly in the first bonding roller pair 61. In addition, a sprocket 64a fixed to the photo feed roller shaft 60c and the upper roller shaft 61 of the first bonding roller pair 61 is fixed to upper and lower roller shafts 62c and 62d of the second bonding roller pair 62. The sprocket 64b has a small diameter with a reduced number of teeth, and its peripheral speed (feed speed V3) is changed.

As shown in FIG. 10, the first bonding roller pair 61 is composed of an upper driving roller 61a and a lower pressing roller 61b, and a postcard 35 on which an adhesive tape 25 is adhered. By nipping and transporting the photo 55 in a superimposed state, the adhesive tape 25
As a result, the postcard 35 and the photograph 55 are securely attached. A gap 68 is formed between the first bonding roller pair 61 and each of the rollers 61a and 61b.
Is smaller than the thickness of the superimposed photograph 55 and the postcard 35. Also, the lower pressing roller 61b
Is configured to be shiftable downward, and is urged upward by a coil spring (not shown).

Therefore, before the postcard 35 and the photograph 55 are inserted into the nip portion 61e, the lower pressing roller 6
1b is in a free state without rotating. When the postcard 35 and the photograph 55 are inserted, as shown in FIG. 11, the driving roller 61a and the pressing roller 61b convey these in a nip state. At the time of this bonding, the lower pressing roller 61b makes the postcard 35,
The pressure-sensitive adhesive tape 25 is shifted downward in accordance with the thickness of the photograph 55, and the pressing roller 61b is urged upward, so that both are securely bonded to each other.

As shown in FIG. 10, the photo feed roller 60 transfers the photo 55 to the nip portion 61e of the first bonding roller pair 61 on the upstream side in the feed direction and the peripheral surface 61f of the lower pressing roller 61b. The photograph 55 is sent so that the photograph tip 55a comes into contact with and stops. The conveying force of the photo paper feed roller 60 is set to be weak, and when the front end 55a of the photo comes into contact with the peripheral surface 61f of the lower pressing roller 61b, the photo feed roller 60 runs idle and stops its feeding. The conveyance force can be adjusted by changing the width of the roller 60, changing the coefficient of friction with the photograph 55, changing the roller pressing force on the photograph 55, and the like. The tip portion 63c of the upper postcard guide 63a is notched diagonally, and a photographic guide 69 is formed by this inclined surface.

The postcard guides 63a and 63b are formed by adhering the postcard 35 to which the adhesive tape 25 is pasted, to a pair of rollers 61.
Is guided by a predetermined amount, for example, 2 mm, on the peripheral surface 61f of the lower pressing roller 61b to the upstream side in the postcard feeding direction from the contact position of the photograph leading end 55a. This allows
The sent postcard 35 with the adhesive tape 25 hits the leading end 55a of the photograph 55 which is in contact with the pressing roller 61b and stands by. With this contact, the adhesive tape 25 comes into contact with the photograph 55, and the two move together in a state where the photograph tip 55 a and the postcard tip 35 b are aligned with each other.
The nip is conveyed at one nip portion 61e. Therefore,
The postcard 35 and the photograph 55 are bonded together by the bonding roller pair 61 in a state where the tips 35b and 55a are aligned.

As shown in FIG. 3, the roller pair 45, 6
The shaft 45 of each drive-side roller 45a, 61a
c, 61c and a sprocket 4 attached thereto
A one-way clutch 58 is mounted between the clutches 6 and 64a. The one-way clutch 58 allows the rollers 45a, 61 to rotate faster than the rotational speeds of the sprockets 46, 64a.
a can rotate faster.

The sprocket 64b of each roller shaft 62c, 62d of the second bonding roller pair 62 has a smaller diameter than the sprocket 64a fixed to the upper roller shaft 61c of the first bonding roller pair 61. Thereby, the postcard attaching section 17 and the first attaching roller pair 61
For postcard feed speeds V1 and V2 (V1 = V2),
The postcard feed speed V3 of the second bonding roller pair 62 becomes slightly higher. Therefore, when the postcard 35 and the photograph 55 reach the second bonding roller pair 62, the postcard 35 is sent at the feed speed V3 of the second bonding roller pair 62. At this time, since the one-way clutch 58 operates, the postcard feed roller pair 45 and the first bonding roller pair 61
Then, the postcard 35 is sent at the feed speed V3.

As a result, a gap is generated between the first postcard 35 and the next postcard 35 due to a difference in feed speed. Since this gap gradually increases with the elapse of the feeding time, each postcard 35 separates, and as shown in FIG. 8, when the separation amount of each postcard 35 exceeds a certain value, the adhesive tape 2
5 is cut off. The length of the conveyance path 36 in this part is set so that the separation position of the adhesive tape 25 is a position where the tip of the next postcard 35 has passed the pressing roller 44. The next postcard 3
5 is smoothly guided without hitting the pressing roller 44. In addition, the postcard tip portion 35a does not deviate from the transport path 36 and is not located above, and the paper is reliably transported.

As shown in FIG. 12, the controller 70 controls the rotation of each of the motors 48 and 66 via drivers 71 and 72. Therefore, in addition to the power switch 73, the controller 70 has a start switch 74,
5 is connected. Further, a processing number counter 76 is provided in the controller 70.

The processed number counter 76 counts the number of sheets to be pasted on the postcard 35 and the photograph 55 based on the amount of the adhesive tape fed. The adhesive tape feed amount may be detected by counting the number of drive pulses of the postcard attaching motor 48, or alternatively, a rotary encoder may be provided and detected from an output signal of the rotary encoder. The number of processed sheets may be calculated based on the output signal of a sensor that detects the passage of the postcard 35 or the photograph 55, in addition to the calculation based on the amount of the adhesive tape fed.

The number input unit 75 includes a numeric keypad.
Input the number of processed sheets. The number input unit 75 may use a dial switch, other input means, or the like, instead of using the numeric keypad.

Next, the operation of the present embodiment will be described. First, the same number of postcards 35 and photographs 55 to be attached are set in the storage sections 12 and 18. Also, the number input section 75
The number of the postcard 35 and the number of photos 55 set by the user are input. Next, when the start switch 74 is turned on, the motors 48 and 66 rotate. Thereby, each roller 40, 4
4, 60, and roller pairs 41, 43, 45, 61, 62
Rotates. Then, the adhesive tape 25 of the double-sided tape 15 is attached to the uppermost postcard 35 by the rotation of the attachment paper feed roller 40, and is sent out to the transport path. The postcard 35 is nip-conveyed by the adhesive roller pair 41, so that the adhesive tape 25 is securely attached to the postcard 35. The peeling tape 23 is peeled off from the adhesive tape 25 by the peeling guide plate 42 and the postcard holding roller 44, and only the peeling tape 23 is a peeling tape feed roller pair 43.
Is sent upward. Then, the release tape 23 is wound around the winding core 24.

In the first postcard 35, since there is no preceding postcard, after passing the separation guide plate 42, the tension of the separation tape 23 causes the adhesive tape 25
May be peeled off, for example, by about 5 mm. Also, as shown by the two-dot chain line in FIG. 6, the postcard tip 35a may be pulled upward by the tension of the release tape 23 and may be displaced from the postcard transport path 36. However, in the present invention, since the pressing roller 44 is provided near the distal end of the peeling guide plate 42 and the roller 44 is rotated in the postcard feeding direction, the postcard distal end 35a is surely returned to the transport path 36. . Further, only the peeling tape 23 is peeled off from the adhesive tape 25 without the adhesive tape 25 adhered to the postcard 35 being peeled off by this return.

When the first postcard 35 is pulled out from the postcard storage unit 12, the next postcard 35 is attached to the paper feed roller 4
Thus, it comes into contact with the zero adhesive tape 25. Therefore, the succeeding postcard 35 is fed almost in a continuous state with the adhesive tape 25 adhered thereto, with almost no gap between the postcard 35 and the previous postcard 35.

On the other hand, as for the photograph 55 in the photograph storage section 18, only the photograph 55 in contact with the photograph feed roller 60 is sent downward. Then, as shown in FIG. 10, when the leading end 55a comes into contact with the peripheral surface 61f of the lower pressing roller 61b of the bonding roller pair 61, the photo paper feeding roller 60 idles and the feeding of the photo 55 stops. . When the first postcard 35 reaches the photo sticking section 19 by the postcard feed roller pair 45, the postcard tip 35b becomes the photo tip 55.
In step a, the two are aligned.

The postcard and the photograph, both ends 35b and 55a of which are aligned and integrated with the adhesive tape, reach the nip portion 61e of the first bonding roller pair 61, are nip-conveyed, and are bonded together. Is performed. As described above, by keeping the photograph front end 55a in the postcard transport path and passing the postcard 35 having the adhesive tape 25, without performing complicated control using a sensor or the like,
Both ends can be easily aligned.

As shown in FIG. 9, the postcard feeding speed V3 of the second bonding roller pair 62 is set to
And the postcard feed speed V of the first bonding roller pair 61
1, faster than V2. Further, the length of the transport path is set such that when the postcard 35 reaches the second bonding roller pair 62, the rear end of the postcard 35 is located at a position past the separation guide plate 42. Therefore, the gap between the preceding postcard 35 and the succeeding postcard 35 gradually increases due to the difference in postcard feeding speed. Then, when the rear end of the postcard 35 passes through the pressing roller 44, the gap between the preceding postcard 35 and the succeeding postcard 35 further widens. When this gap reaches a certain amount, as shown in FIG. 8, the adhesive tape 25 is cut off, and these postcards 35 are cut off. As described above, since the adhesive tape 25 is cut off according to the difference in postcard feeding speed, a cutter or the like is not required and the configuration is simplified.

When the preceding photograph 55 is pulled out from the photograph storage section 18, the next photograph 55 is similarly pulled out almost continuously. Then, the leading end 55b of the photograph comes into contact with the peripheral surface 61f of the pressing roller 61b of the first bonding roller pair 61 and stops, and the next postcard 35 is in a standby state. Postcard 3
5 is sent almost continuously, so the leading edge 5
The first bonding roller pair 61 nips 5a with the postcard tip 35b aligned. In this way,
The postcard 35 and the photograph 55 are continuously and rapidly bonded.

The number of processed sheets is counted from the feed amount of the adhesive tape 25 or the sensor or the like. When the number of processed sheets reaches the number set in the number input section 75 in advance, each motor 48,
66 stops, and the bonding operation is completed. The bonded postcard 35 and the photograph 55 can be used as they are, but usually, it is preferable to cut off four rounds because both sizes are different and a slight misalignment may occur. This cutting is performed using a known cutting device such as a slitter or a shearing cutter. In addition,
The cutting device may be incorporated in the photo pasting machine, or a cutter provided separately may be used.

In the above embodiment, the number of sheets to be processed is input, and when the number of sheets to be processed is reached, the operation of each of the motors 48 and 66 is stopped to end the work. Postcard 3 is stored in the section 12 and the photo storage section 18.
5 and the photo 55 are empty, and a motor 48, 66 is provided based on the sensor output.
May be controlled by stopping.

In the above embodiment, the two motors 48, 6
Although 6 is used, each pasting unit and the like may be driven by a single motor. In this case, it is preferable to change the postcard feed speeds of both attaching portions by changing the gear ratio and the like. Further, instead of driving by a motor, a handle may be provided, and by rotating the handle, the roller of each attaching portion may be rotated. Further, both the motor and the handle may be provided, and these may be selectively used.

In the above embodiment, when the conveying force of the photo feed roller 60 is adjusted and the photo tip 55a comes into contact with the lower pressing roller 61b of the first bonding roller pair 61, the feed roller 60 To stop the feeding of the photograph 55, but in addition to this, using the sensor and the electromagnetic clutch brake, when the leading end 55a of the photograph reaches the pressing roller 61b, the electromagnetic clutch is operated to supply the photograph 55. The paper may be stopped.

In the above embodiment, the feed speed V2 of the first and second laminating roller pairs 61 and 62 of the photo laminating section 19
V3 is changed, but these feed rates may be the same. Also in this case, the feed speed V1 of the
The feed speed V2 of the photo affixing section 19 is set to be slightly higher than that, and the adhesive tape 25 is separated between the postcards 35 by the difference in the feed speed. In addition, although the first and second bonding roller pairs 61 and 62 are provided and the bonding is performed in two steps, the bonding may be performed in one step or three or more steps.

However, the present invention is not limited to this. The leading end 55a of the photograph may be kept on standby in the transport path. In this case as well, the postcard 35 to which the adhesive tape 25 has been applied passes, so that the adhesive tape 25
The two ends are adhered to each other via the interface, so that the two ends are automatically aligned.

In the above embodiment, the postcard 35 and the photograph 55 are laminated, but the object of lamination of the photograph 55 is not limited to the postcard 35, and another cut sheet type card may be used. The present invention is not limited to the photograph 55, and may be applied to a case where two types of cut sheets are pasted together.

In the above embodiment, the rollers 40, 44, 6
0, feeding and bonding are performed using the roller pairs 41, 45, 61, and 62. However, feeding and bonding may be performed using an endless belt.

In the above-described embodiment, as a means for cutting the adhesive tape 25 between the front and rear postcards 35 after the adhesive tape 25 is attached to the postcard 35, a speed difference (V1 < V3), a sensor 80 for detecting the postcard 35 and the photo 55 attached to the photo pasting unit 19 as shown in FIG.
The adhesive tape 25 may be cut by temporarily stopping the rotation of the postcard application motor 48 on the postcard application section 17 based on the postcard detection signal of the sensor 80. In this case, the subsequent postcard 35 stops,
The adhesive tape 25 can be more reliably cut.
In this embodiment, the conveying speeds V1, V2, and V3 of the roller pairs 45, 61, and 62 are set to be the same, and only one direction is provided between the upper roller shaft 45c of the postcard feed roller pair 45 and the sprocket 64a. A clutch 58 (see FIG. 3) is provided. The sensor 80 may be a mechanical sensor in addition to various optical sensors such as a photo interrupter type and a reflection type. In FIG. 13, the same components as those in the embodiment of FIG. 9 are denoted by the same reference numerals.

According to the present invention, the adhesive surface of the double-sided tape is pressed against the leading end of the card in the card storage section and the card is sent to the sticking section. It can be continuously adhered to the adhesive tape. Moreover, since the adhesive tape is attached to the postcard at an initial stage, the handling becomes easy. In addition, since the pressing roller is provided on the downstream side in the card feeding direction with respect to the release tape guide member, the release tape can be reliably peeled off from the double-sided tape. Further, the occurrence of peeling of the leading end of the adhesive tape in the first card is suppressed.

Since the card feeding speed of the sticking / conveying unit is higher than the card feeding speed of the double-sided tape pressure-feeding member, there is no need to separately provide an adhesive tape cutting means, and the adhesive tape can be easily secured at the front and rear ends of each card. Can be cut into Moreover, complicated processing for cutting is not required. In addition, in order to provide a speed difference, the adhesive tape can be more reliably separated by temporarily stopping the card feeding speed of the double-sided tape pressure-feeding member at 0. Further, since the pair of transport rollers is used, the card and the photograph can be easily and reliably adhered via the adhesive tape.
