Abstract

PURPOSE:To increase the speed of sticking by sucking and picking up the upper most sheet of stacked paper sheets, pushing it out in the horizontal direction at the same time as suck release, and feeding its tip end in the stopper direction by a feed out roller immediately. CONSTITUTION:The upper most sheet in paper sheets P stacked on a holder H is sucked and picked up by the sucking part 4 of a pick up device 1 and pushed out to a feed out roller 23 side horizontally by the push out part 13 of the push out device 11 at the same time as the release of suction of the paper sheet P picked up by the pick up device 1. Thereby, the tip end of the paper sheet P reaches the feed out roller 23 immediately and the paper sheet P is fed to a stopper 22 immediately by the feed out roller 23 and a feed assistant roller 24. The drop of the paper sheet P can be prevented by setting the distance between the feed out roller 23 and the stopper 22 slightly longer than the length of the paper sheet P and a continuous belt type sheet S can be stuck by a sticking device 31 continuously.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is extremely effective in continuously adhering paper sheets to a continuous strip-shaped sheet material with a device having a simple structure and at a desired position of the continuous strip-shaped sheet material. The present invention relates to a paper sheet delivery and adhering mechanism in a continuous paper sheet adhering device for adhering a sheet reliably and quickly to a continuous strip-shaped sheet material.

[0002]

2. Description of the Related Art Conventionally, an apparatus for sticking paper sheets to a continuous strip-shaped sheet, in particular, an apparatus for sticking a thin postcard to a continuous strip-shaped sheet on which patterns, characters, figures, etc. are provided, has been provided to various markets. However, most of the devices are applied in the same method.

The basic method of the apparatus is that a double-sided adhesive tape wound in a roll shape is drawn out in parallel on a sheet material on which a pattern, characters, figures, etc. drawn from a roll-shaped continuous strip-shaped sheet are applied. The double-sided tape is attached to the back surface of the sheet material, and the release paper is removed from the double-sided tape so that the paper sheet can be attached to the back surface of the sheet material, and the sheet is stacked there. The paper sheet is attached to the back surface of the sheet material by sandwiching the sheet material with the base so that the sheet material is crimped. Then, at that time, if the sheet material is continuously pulled out and transferred, a positional deviation often occurs when the paper sheet is stuck. Therefore, the sheet material may be transferred intermittently. When the transfer of the sheet is stopped, the sheet is attached to the sheet material by synchronizing the sheet material to the back surface of the sheet material.

As a typical device thereof, for example, Japanese Patent Laid-Open No. 63-70858 discloses a postcard print manufacturing device.

Further, instead of the double-sided adhesive tape, a water-soluble adhesive is applied and the paper sheets are stuck together.

[0006]

However, this apparatus intermittently transfers the sheet material, and when the transfer of the sheet material S is stopped, the sheet P is synchronized with the back surface of the sheet material by pressure. Since the paper sheet is stuck to the sheet material by this, the sticking speed is very slow because the sheet material is repeatedly stopped and transferred, which is a big problem.However, as described above, if the sheet material is continuously transferred, It is not possible to suppress the generation of defective products due to frequent sticking position deviations, and it is possible to increase the mass production speed to a certain extent, but it is not possible to expect further improvement in the mass production speed. The current situation was that no development was done.

Further, since the double-sided adhesive tape is used for sticking the paper sheet, there is a problem that the price becomes high.

Furthermore, when a water-soluble adhesive is used instead of the double-sided adhesive tape, drying is performed to remove the solvent of this adhesive before and after the sticking of the paper sheet. The attached continuous strip sheet material curls,
Alternatively, there is a problem that defective products such as peeling of the cured adhesive are generated.

Therefore, the applicant of the present application has filed Japanese Patent Application No. 2-211.
In No. 845, a continuous paper sticking device for a continuous strip-shaped sheet material, a paper feeding method for the continuous paper sticking, and a paper feeding mechanism thereof have been proposed.

According to the present invention, a sheet material supplying section for continuously supplying a continuous belt-shaped sheet material having a pattern, a character, a figure, etc., and a continuous belt-shaped sheet material fed from the sheet material supplying section are adhered. An adhesive applying device for applying an agent, a sheet material position detecting device for detecting small through holes formed on the side edge of a continuous strip-shaped sheet material to detect the position of a picture, a character, a figure, etc. A sheet delivery mechanism that operates in response to a signal detected by the position detection device to detect a small through-hole, and delivers appropriate sheets to be attached to the sheet material from the sheet storage unit one by one to the attachment position on the continuous strip sheet material. And a sticking-out device that sticks out the paper sheets sent to the pasting position onto a continuous strip-shaped sheet material and carries them out.The paper sheet feeding mechanism uses one paper sheet stacked in the paper sheet storage section. Paper picking device for picking up paper one by one and picked paper leaves Formed from a delivery device for delivering to a position where the continuous strip-shaped sheet material is pasted, and a paper sheet detection device that is arranged between the paper sheet take-out device and the pasting position to detect a paper sheet that is sent out The apparatus sequentially arranges a first paper sheet detector, a second paper sheet detector, and a third paper sheet detector from the side of the paper sheet take-out device toward the pasting position, and the first paper sheet detector sends out the paper sheet. It is formed to detect whether there is only one sheet to be printed, and to send a command to stop the whole operation when it is not one sheet, and the second sheet detector is close to the third sheet detector. And the sheet is being sent out, and is formed so as to send a command to detect the sheet being sent out and reduce its feed speed. To the continuous strip-shaped sheet material formed to detect the sheet being sent out and send a command to stop the feeding. It is a continuous paper sticking device, and first, the paper sheets stacked in the paper sheet storage section are taken out one by one by the paper sheet take-out device, and the taken-out paper sheets are made by the sending-out device. To the pasting position of the sheet, and in the middle of the delivery, the first sheet detector, the second sheet detector, and the third sheet detector in the delivery direction from the sheet take-out device side. First, the first sheet detector detects whether or not the number of sheets to be sent out is one, and when it is one, it is sent as it is, and when it is two or more. The paper feed is stopped by stopping the entire operation, then the paper fed by the second paper detector is detected, the feed speed of the paper is decelerated, and finally , The continuous sheet that is decelerated by the second detection body is detected by the third detection body and stopped at the pasting position. It is a paper delivery method for attaching paper sheets, and further, a paper sheet take-out device for taking out the paper sheets stacked in the paper sheet storage section one by one, and the taken-out paper sheet pasting position of this paper sheet. And a sheet detecting device arranged between the sheet take-out device and the pasting position to detect the sheet to be delivered. The first sheet detector, the second sheet detector, and the third sheet detector are arranged in this order from the device side toward the pasting position, and the first sheet detector outputs one sheet. It is formed to send a command to stop the whole operation when it is not one sheet, and the second sheet detector is placed close to the third sheet detector and is sent out. Is formed so as to detect a paper sheet that is present and send a command to reduce the feed speed, and the third paper sheet detection body is arranged near the pasting position. It is paper sheet delivery mechanism for the continuous paper sheet stuck formed to send a command to stop the feeding by detecting the paper sheet being delivered Te, but is characteristic.

Therefore, the present invention solves the above-mentioned problems, and continuously supplies a continuous strip-shaped sheet material having a pattern, a character, a figure, etc. to the sheet material.
It has the excellent effect that paper sheets can be attached to continuous and accurate positions appropriately, the mass production speed of the products formed thereby can be markedly improved, and the manufacture of excellent products without defective products can be ensured. is doing.

However, among them, in the paper sheet feeding mechanism for sticking continuous paper sheets, the second paper sheet detector is arranged close to the third paper sheet detector and is sent out. It is formed to detect a sheet and send a command to reduce the feeding speed, and the third sheet detector detects the sheet that is delivered in the vicinity of the pasting position and stops the feeding. Since it is formed so as to send a command to cause the paper to be sent, the time between picking up and sending the paper and stopping it is wasted, although it is a little because of the deceleration and the stop.

This slightly wasteful time is often a certain amount of time when processing a large number of sheets, and in a continuous sheet sticking device for a continuous strip-shaped sheet material, the time is further shortened. There has been a demand for improvement of the paper feeding and sticking mechanism.

Therefore, in view of the above-mentioned points, the present invention provides a method for continuously attaching paper sheets to a continuous strip-shaped sheet material.
It is an object of the present invention to make it possible to attach paper sheets reliably and quickly at a desired position on a continuous strip-shaped sheet material with an extremely simple device.

It consists of a feeding device and a sticking device for sticking the fed paper sheet to a continuous strip-shaped sheet material, and the feeding device is a stopper for stopping the paper sheet extruded by the extruding device at the attaching position, and an extruding device. It consists of a delivery roller that is rotating so as to constantly deliver the paper sheet in the state of being pushed toward the stopper, and the distance between this stopper and the delivery roller is a little shorter than the length of the paper sheet. The release of suction to each paper sheet by the device is formed so as to be controlled so as to be performed almost at the same time as the extrusion of the sheet by the extrusion device, and the sheet is immediately extruded by the extrusion device. The problem described above is solved by setting the position of the delivery roller so that the tip of the delivery roller immediately reaches the delivery roller.

[0016]

In the continuous sheet sticking device for a continuous strip-shaped sheet material according to the present invention, the sheet feeding and sticking mechanism first sets the sheets stacked by the pickup device from the uppermost sheet 1

The paper sheet sent to the delivery roller is immediately sent in the stopper direction and is sent to the stopper as it is because the delivery roller is constantly rotating to send the paper sheet in the direction of the stopper. Since the force is applied to the paper sheet, the paper sheet always comes to a position accurately stopped at the position of the stopper. And in that state, the distance between the stopper and the delivery roller is slightly shorter than the length of the paper sheet, so the paper sheet does not drop, and it does not almost bend and is accurately positioned at the stopper position. It is in a state of being stopped and placed.

Then, the paper sheet stopped at the position of the stopper is stuck to the continuous strip-shaped sheet material by a sticking device.

Therefore, the paper sheet is fed without deceleration from the picking up to the feeding to the predetermined pasting position.

Then, the picked-up paper sheet P is extruded in a substantially horizontal direction by the extruding device 11 at the same time when the suction is released. Then, immediately after the sheet P is extruded by the extruding device 11, the leading end of the sheet P immediately reaches the feeding roller 23 of the feeding device 21.
Since the position is set, even if the suction is released, the paper sheet P is immediately sent out and sent to the roller 23, so that it does not drop. Therefore, it is sent to the position of the stopper 22 without dropping.

At that time, the paper sheet P sent to the delivery roller 23 is immediately delivered to the stopper 22 because the delivery roller 23 is constantly rotating to deliver the paper sheet P toward the stopper 22. Moreover, since the force is applied so as to be sent to the stopper 22 as it is, the paper sheet P is always stopped accurately at the position of the stopper 22. In this state, the distance between the stopper 22 and the delivery roller 23 is slightly shorter than the length of the paper sheet P, so that the paper sheet P does not drop, and the stopper 22 hardly bends. It will be in the state of being accurately stopped and arranged at the position.

Then, the paper sheet P stopped at the position of the stopper 22 is attached to the continuous strip sheet material S by the attaching device 31.

Therefore, the paper sheet P is sent without deceleration from the picking up to the feeding to the predetermined pasting position.
