Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing postcards using a photograph on one side.

[Prior Art] In recent years, so-called postcards made by Photor1 with an image printed on the back have become popular. However, since these postcards are made of photographic paper, there is a problem in that you are limited in the writing utensils you can use when writing the address on the surface, and since they are my own products, it is necessary to affix a stamp to each postcard, which makes it difficult to ship in large quantities. It took a lot of effort.

Recently, a type of postcard with a photo pasted on the back of an official postcard was developed.

[Problems to be solved by the invention] However, in the case of such recently developed postcards, the photo and official postcard are attached using double-sided tape, resulting in high manufacturing costs, increased thickness, and the need for punching. There were problems such as the need for high precision in the work.

The present invention has been made in view of these circumstances.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention applies adhesive to the base side of a photographic strip formed by consecutively arranging imaged cuts at equal intervals, and then sets the official postcard. Partial pasting is achieved by placing the glue-coated side of the photo strip on the back side of the photo strip facing each image cut, and partially pressing the photo strip against the official postcard.
Subsequently, the official postcard is passed between pressure rollers to be pasted on the entire surface of the photographic strip to integrate it, and then cut into pieces using a slitter and a paper cutter.

[Operation] When the photo strip is moved with a government postcard partially pasted on the photo strip, only one government postcard will be picked up, passed between the pressure rollers to make it completely adhered, and further aligned with the cut. By cutting it, it becomes a postcard with an official postcard on the front and a photo on the back.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

The figure shows an apparatus for carrying out the method of the invention,
An uncoiler 2 rewinds a coil (roll) of a photographic strip (roll paper) L formed by consecutively arranging (printing) photographic cuts at equal intervals while applying a constant braking force, and an uncoiler 2 that unwinds a coil (roll) of a photographic strip (roll paper) L formed by consecutively arranging (printing) photographic cuts at equal intervals; There is a coating machine 3 that applies glue to the back side of the photographic strip 1 while continuously rewinding it by a drive, and a coating machine 3 that sprays hot air on the coated glue so that the optimum adhesive strength (adhesive strength) can be obtained in a subsequent process. A conditioner 4 that performs processing, a feeding device 6 that sequentially feeds out the government postcards 5 stacked in the vertical direction, and a glue-applied surface of the photo strip 1 partially pressed against the government postcards 5 to pick up the government postcards 5 one by one. a pickup device 7; a crimping device 11 for crimping and pasting the picked up government postcard 5 onto the photo strip 1;
A recoiler 9 winds up the photographic strip 1 after pasting it into a coil (roll) shape with a constant winding force that is weaker than the driving force of the crimping device 11, and a punch mark formed in the longitudinal direction of the width end of the photographic strip 1. It is equipped with a cut mark sensor lO such as a punch mark or the like that detects and sends an intermittent drive command to the crimping device 11 so as to correspond to the pickup operation with the imaged cut, and is arranged to allow the photographic strip l to pass through each of the above steps. Guide rollers 8a to 8e, a weight roller 12 which can be raised and lowered and arranged to form a loop of the photographic belt l between the guide rollers 8a and 8b, and the raising and lowering position of the weight roller 12 are detected by, for example, a translucent method. It has upper and lower loop sensors 13 and 14 that send drive and stop commands to the crimping device 11, and is further equipped with a slitter that cuts the width end of the photographic strip 1 for post-processing, and a paper cutter that cuts each cut. There is.

Next, the work process will be explained.

First, the coil of the photographic belt 1 set in the uncoiler 2 is unwound, and a guide band previously provided at the tip of the photographic belt 1 is connected to the recoiler 9 via each guide roller 8a to 8e.

In this state, the pace roller 3 of the coating machine 3
a and the pressure bonding device 11 are driven to unwind the photographic strip 1 from the uncoiler 2, and a coater 3 coats the back surface (base surface) with glue. The photographic strip l coated with glue is pre-dried with a conditioner 4 to obtain optimum adhesion.

The pre-dried photographic belt l forms a loop with the weight roller 12 and then reaches the pickup device 7. At this time, the cut position of the photo belt 1 is detected by the cut mark sensor 10 using punch marks or the like, the crimping device 11 is stopped, and the pickup device 7 is activated.

The pickup device 7 has a pressing roller 15 at one end, and a middle part of an operating arm 17 connected to a solenoid 1B as an actuator at the other end is attached to a fixed member with a pin 18.
It is pivotally mounted and includes a restoring spring 19 for holding the operating arm 17 in a fixed position when the solenoid 16 is in a demagnetized state. Therefore, when a command is received from the cut mark sensor 10, the solenoid 1B is energized, the operating arm 17 is rotated about the pin 18, and the pressing is performed by displacing the roller 15 to the position shown by the two-dot chain line and pressing the photographic belt 1. The back side, that is, the glue-applied side, is pressed against the top official postcard 5 held by the feeding device 6. By this pressing, the photo strip 1 and the official postcard 5 are partially adhered. By setting the solenoid 16 to be demagnetized after a certain period of time, the restoring spring 19 returns the pressed roller 15 to its original position. solenoid 1
When the crimping device 11 is driven simultaneously with the demagnetization of B, the official postcard 5 partially adhered to the photographic strip 1 passes through the crimping device 11 as the photographic strip 1 moves, and is crimped there. That is, the official postcard 5 is completely pasted on the photo strip 1 and integrated.

The crimping device 11 includes upper and lower crimping rollers 20 and 21 driven by pulse motors or servo motors, a powder roller 23 that applies powder 22 to the lower crimping roller 21, and a container 24 that stores the powder 22. Powder 22 is attached at the same time as the pressure tube to facilitate post-processing. Note that one of the pressure rollers 20 and 21 may be used as an idler.

The photo strip 1 that has passed through the crimping device 11 is sequentially wound around the rela-coiler 9 with the official postcards 5 pasted thereon, and after the predetermined pasting work is completed, it is unwound again and the width edges are cut off by a slitter. , each cut is cut by a vapor cutter, resulting in an integrated postcard with a government postcard 5 on the front side and a photograph on the back side.

In the above, the photographic strip 1 is intermittently moved so as to be sent to the pickup device 7 for each cut by the cut mark sensor 10, but the pace roller 3a of the applicator 3 is driven synchronously with the intermittent drive of the crimping device 11. There is no need to drive it continuously; it is sufficient to drive it continuously. That is, since the photographic belt 1 is wound around the weight roller 12 to form a loop, if the pressure bonding device 11 is driven while the applicator 3 is stopped, there is no room for the loop and the weight roller 12 rises.
Unreasonable tension is applied to the photographic band 1. Therefore, the loop sensor 14 detects the rise of the weight roller 12, and sends a standby command to the crimping device 11. When the crimping device 11 enters the standby state, the loop has a margin, so the weight roller 12 descends further below the loop sensor 14. When the weight roller 12 descends below the loop sensor 14, a drive command is sent to the crimping device 11. However, the speed of the crimping device 11 is set to be faster than the speed of the coating machine 3. By repeating such operations, it is possible to prevent undue tension or slack from occurring due to out of synchronization. Note that the loop sensor 13 may not be connected to the weight roller 12 for some reason.
rises above the loop sensor 13,
A command is issued to emergency stop the crimping device 11 or the entire device.

In addition, in the above, in order to feed out the official postcards 5 one by one in response to the pick-up device 7, the official postcards 5 must be placed at a constant position at all times, but in the present invention, it is possible to achieved. That is, the feeding device 6 includes a holder cylinder 25 that holds a large number of government postcards 5 stacked vertically in the lower part of the pickup device 7, and a level block 26 placed on the top surface of the government postcards 5 in the holder tube 25. A transmission member 27 that is integrated with the level block 26 and moves up and down on the side of the holder cylinder 25, a striker 29 that rotates about a pin 28 when the transmission member 27 is lowered, and a striker 29 that rotates several times. It consists of a feed-out sensor 30 that is activated when the holder is moved, and a feed-out jack (motor, cylinder, etc.) 31 that supports the official postcard 5 in the holder tube 25 from its lower part and moves up in response to a command from the feed-out sensor 3o. Therefore, when the official postcards 5 at the top level in the holder tube 25 are picked up one after another and the level of the top official postcards 5 is lowered, the level block 26 is lowered accordingly. When the level block 26 descends, the transmission member 27 also descends together, and the striker 29 rotates about the bin 28 as a fulcrum. This rotation of the striker 29 activates the feed sensor 30, and the feed jack 3 is raised to push the position of the official postcard 5 on the top surface to a predetermined level. In this way, the official postcard 5 on the top side is always placed at a constant position.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and for example, a slitter 32 and a paper cutter 33 may be arranged downstream of the crimping device 11 as shown by the two-dot chain line.
Of course, the winding operation by the recoiler 9 may be omitted, cut marks other than punch marks may be used, and various other changes may be made without departing from the gist of the present invention.

[Effects of the Invention] As explained above, according to the postcard manufacturing method of the present invention, (1) Since it uses an adhesive method using glue, it is cheaper and thinner than the double-sided tape method. Can be done.

(n) There is no need to perform high-precision punching work, so
