Description

[Detailed Description of the Invention] The present invention relates to an improvement in a paper laminating machine that polymerizes and adheres a cover of printed paper, sheets, etc. and a backing paper such as cardboard or corrugated paper.

Conventionally, this type of interleaving machine was manufactured by Jikosho, for example.
The one disclosed in Japanese Patent No. 56-6480 is known.

This consists of an upper sheet feeding device for supplying covers cut to predetermined dimensions, an upper sheet feeding device for conveying covers at regular intervals, and a backing paper cut to predetermined dimensions. a lower paper feeding device for conveying paper at regular intervals, a lower regular interval paper feeding device that conveys the mount paper at regular intervals in synchronization with the upper regular interval paper feeding device; The main parts are comprised of a gluing device and a pasting device that superimposes and pastes together the cover that has passed through the upper regular interval paper feeding device and the backing paper that has passed through the gluing device.

Therefore, in such a paper laminating machine, its laminating device is
Usually, it is constructed with two sets of upper and lower laminating rolls, front and back, and because the cover and mount must be immediately laminated to form a product, a relatively quick-drying glue is used.

However, this type of glue dries quickly but has the drawback of being expensive.

For this reason, it is possible to use an inexpensive glue such as starch glue, but in this case, it takes time to dry and sufficient adhesion cannot be obtained by simply applying pressure in the laminating device. There was a risk that the cover and the mount would peel off afterward.

This invention was devised to solve the problems mentioned above, and its purpose is to:
To provide a paper interleaving machine capable of adhering well even when using glue that takes a long time to dry.

The interleaving machine of the present invention includes an upper sheet feeding device for supplying covers cut to a predetermined size, an upper sheet feeding device for conveying the covers at regular intervals, and a paper feeder for feeding covers cut to a predetermined size. a lower sheet feeding device for feeding the mount paper, followed by a lower regular interval paper feeding device for conveying the mount paper at regular intervals in synchronization with the upper regular interval paper feeding device; a pasting device for superimposing and pasting together the cover that has passed through the upper regular interval paper feeding device, the cover that has gone through the pasting device, and the mount that has passed through the pasting device, and the pasting device. It consists of only a lower belt conveyor installed at the next stage and an upper belt conveyor that can move up and down freely relative to the lower belt conveyor, which is driven at a slower speed than the laminating device and conveys the laminated material while clamping it in an inclined state. The feature lies in that it is composed of a dry compression bonding device.

In other words, a dry pressure bonding device consisting of upper and lower belt conveyors is provided next to the pasting device of the conventional paper laminating machine.

According to the present invention, the following excellent effects can be achieved.

(1) Since the dry pressure bonding device is installed next to the bonding device, good adhesion can be achieved even when using glue that takes time to dry, and there is no possibility that the cover and the mount will peel off afterwards.

(2) Since it is possible to use an inexpensive glue such as starch glue, which takes time to dry, running costs can be reduced.

(3) Since the drying and pressure bonding device consists of only a lower belt conveyor and an upper belt conveyor that can freely move up and down relative to the lower belt conveyor, the bonded product can be naturally dried.
Since the glue applied by the gluing device uniformly impregnates not only the mount but also the cover, wrinkles and distortions do not occur, and the cover and mount can be properly aligned after pasting.

(4) The dry pressure bonding device can press the bonded material using the weight of the lower belt conveyor and the upper belt conveyor that can freely move up and down relative to the lower belt conveyor.

(5) Since the dry pressure bonding device is driven at a slower speed than the lamination device and conveys the bonded material while clamping it in a state of polymerization slope, the entire length of the dry pressure bonding device and, by extension, the total length of the paper laminating machine can be reduced. It is possible to lengthen the dry pressure bonding time without increasing the length.

(6) The dry pressure bonding device is composed of a lower belt conveyor and an upper belt conveyor that can freely move up and down relative to the lower belt conveyor, and is driven at a slower speed than the bonding device to clamp and press the bonded products in a state of polymerization and inclination. Since the central part of the bonded product is not directly pinched by the upper and lower belt conveyors, especially if the cover of the bonded product is made of corrugated cardboard, the center part of the bonded product is not directly pinched by the upper and lower belt conveyors. It will not collapse under the weight of the conveyor belt.

Embodiments of the present invention will be described below based on the drawings.

The drawing is a schematic diagram showing the structure of a paper interleaving machine according to an embodiment of the present invention.

The interleaving machine 1 includes an upper sheet feeding device 2, an upper regular interval sheet feeding device 3, a lower sheet feeding device 4, a lower regular interval sheet feeding device 5, a gluing device 6, a pasting device 7, and a dry pressure bonding device 8.
