Description

[Detailed Description of the Invention] The present invention relates to a dry pressure bonding device used in a paper laminating machine for polymerizing and bonding 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 sheet feeding device for conveying paper at regular intervals, a lower regular interval sheet feeding device that conveys the mount paper at regular intervals in synchronization with the upper regular interval sheet feeding device, and a lower sheet feeding device provided at a stage subsequent to this for conveying the mount paper at regular intervals. 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.

In order to overcome these difficulties, it is conceivable to install a device that slowly feeds the laminated material to the next stage of the laminating device of the paper laminating machine and press-bonds the laminated material while allowing it to dry naturally.

4 and 5 show the structure of a dry compression bonding device 40 previously conceived by the applicant.

This consists of a fixed frame 41, a lower belt conveyor 42 provided on this, a drive mechanism 43 for driving this, an elevating frame 44 that can move up and down with respect to the fixed frame 41, and an upper belt conveyor 42 provided on this. It consists of a belt conveyor 45.

Thus, the laminated material A from the laminating device (not shown) of the paper laminating machine is fed onto the front portion of the lower belt conveyor 42. Since the lower belt conveyor 42 is driven at a slower speed than the laminating device, the laminated material A is overlapped little by little and is conveyed while being pinched and pressed by the upper and lower belt conveyors 45 and 42. It is dried and crimped.

However, such a dry crimping device 40 has a fixed frame 41 provided with a pair of left and right guide columns 46, and an elevating frame 44 that is movable up and down relative to these, so the structure is simple, but the elevating frame is 44 and the upper belt conveyor 45 may not move up and down in synchronization with the left and right sides, and there is a problem in that they cannot be expected to move up and down smoothly.

This invention was devised to solve the problems mentioned above, and its purpose is to:
To provide a dry press bonding device in which an elevating frame and an upper belt conveyor are raised and lowered in left and right synchronization, and the smooth raising and lowering of these is ensured.

The dry crimping device of the present invention consists of a fixed frame, a lower belt conveyor provided on the fixed frame side, a pair of left and right guide columns supported on the fixed frame side, and an elevating frame provided on each guide column so that it can be raised and lowered. , a pair of left and right rack bodies in the vertical direction provided on each guide column, an interlocking shaft provided on the elevating frame so as to be rotatable around the horizontal axis, and a pair of racks attached to the left and right sides of the interlocking shaft and meshing with each rack body, respectively. It is characterized by being composed of a pair of left and right pinion bodies, and an upper belt conveyor that is provided on the elevating frame and can be raised and lowered relative to the lower belt conveyor.

In other words, rack bodies are provided on the left and right guide columns, and pinion bodies that mesh with the rack bodies are provided on both sides of the interlocking shaft rotatably provided on the lifting frame, so that the left and right lifting frames move up and down synchronously. This is what I did.

According to the present invention, the lifting frame and the upper belt conveyor attached to it are raised and lowered in synchronization between the left and right sides, so there is no chance of them getting caught or strained, and smooth lifting and lowering can be expected. can.

Furthermore, according to the present invention, even if the longitudinal center line of the upper and lower belt conveyors and the longitudinal center line of the bonded material do not match and are eccentric, the upper belt conveyor can maintain a horizontal state without tilting. Since it moves up and down, the bonded material is not pressured unevenly, and uniform pressure bonding can be performed.

In addition, the structure is relatively simple as only the rack body, interlocking shaft, and pinion body are added.
It doesn't cost much.

Next, the operation will be explained based on such a configuration.

Laminated product A from the laminating device (not shown) of the paper laminating machine
is fed onto the lower belt conveyor 3 in a free area formed between the front ends of the lower belt conveyor 3 and the upper belt conveyor 9, respectively.

The lower belt conveyor 3 is driven by a drive mechanism 21 to convey the laminated material A backward, but its conveying speed is set to be slower than that of the laminating device, so that the laminated material A is transported backward. Objects A are slowly conveyed in a state where they are overlapped with each other and are shifted little by little.

Thus, such a bonded material A is gradually air-dried while being pinched between the lower belt conveyor 3 and the upper belt conveyor 9, and then transported out.

When the pasted material A enters between the upper and lower belt conveyors 9 and 3, the elevating frame 5 and the upper belt conveyor 3 move upward.

At this time, the rack body 6, interlocking shaft 7, pinion body 8
Due to this action, the upper main roller 27 of the upper belt conveyor 3 is moved upward while maintaining the horizontal state in synchronization with the left and right sides, and thereafter moves up and down in response to the height of the bonded material A.

Of course, even if the longitudinal center line of the upper and lower belt conveyors 9, 3 and the longitudinal center line of the bonded material A are eccentric, the above-mentioned vertical movement is performed, and the bonded material A is uniformly crimped without being biased. be done.

In the previous embodiment, a case where a back-and-forth movable frame that can move back and forth with respect to a fixed frame was provided was illustrated, but the present invention is not limited to this, and this may be omitted. Therefore, in such a structure, all of the lower belt conveyors and guide columns are provided on a fixed frame.

In the previous embodiment, the elevating frame was divided into two parts, front and rear, but the frame is not limited to this, and may be integrated.

In the previous embodiment, a guide roller was provided between the guide column and the elevating frame to ensure smooth elevating. However, the structure is not limited to this, and the guide roller may be omitted and the structure can be slidably elevated. can.

In the previous embodiment, the upper auxiliary roller was pivotally supported at the pivot point of an appropriate number of links, but the invention is not limited to this, and for example, it may be pivoted directly to the integrated elevating frame.
