PURPOSE:To increase efficiency of the folding operation by distributing a sheet material which is fed downward from a driving roller, to left and right, using a pin; then by creasing the said material alternately, in order, by a part of press rollers which are set face to face on both sides. CONSTITUTION:The sheet material which is fed downward between a driving roller 12 and a pressing roller 13 is distributed to left and right using a pin 14, and a crease 23 is made alternately in order by a pair of press rollers 15, 16 which are set on both sides face to face. The side walls 20 are provided on both sides of the receiver 19 which reciprocally moves left and right, and inside of the walls, a vertically movable weight 22 is installed, and the crease 23 of the sheet 11 is conpulsorily lowered, and the end is pressed by its own weight. A zigzag sheet 11 is produced with high efficiency by the above method.

Description

[Detailed Description of the Invention] The present invention relates to a continuous automatic folding device for sheet-like materials, mainly consisting of a large number of electronic components such as diodes and resistors arranged in parallel and connected at both ends with tape to form a sheet-like material. The purpose is to provide a device for folding things for packaging.

Conventionally, this type of sheet-shaped lightning component parts had to be manually folded when packed into boxes for transportation or storage, which had the drawbacks of low work efficiency and high costs. Additionally, sheet-like materials are sometimes made with creases at predetermined intervals using a press or the like to make them easier to fold, but even in that case, it is necessary to manually fold the material.

The continuous automatic folding device of the present invention is intended to overcome the above-mentioned drawbacks of the prior art, and its purpose is to provide a continuous automatic folding device that makes folds continuously and automatically folds folds.

One embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, a sheet-like material 11 is sent out downward from between a drive roller 12 and a pressure roller 13. This drive roller 12 is rotated at a constant speed by a gear motor (not shown), and a pressure roller 13 presses the sheet-like material 11 onto the drive roller 12. The pressure roller 13 is always pressed toward the drive roller 12 by a coil spring or the like. The sheet-like material 11 that has progressed downward is swung left and right by a pin 14, and creases are sequentially and alternately made by a pair of press rollers 15 and 16 installed on both sides facing each other. The ridges 14 are installed perpendicular to the traveling direction of the sheet-like material 11, and the sheet-like material 11 is pulled out through a pair of press rollers 15 and a pair of press rollers 16. At these end positions, the pin 14 is restricted to move freely in and out of the orthogonal position. The sheet material 11 pulled out from between the press rollers 15 and 16 is then alternately creased by the press rollers 15 and 16, respectively. Each press roller 15 and 16 has a drive side 17
and crimping side 18, respectively, and crimping side 1
8 is connected to the drive side 17 by a rotary solenoid (not shown).
It is regulated so that it can be crimped. Drive side 17
are rotated in the same direction when the sheet-like material 11 is pulled out, and are reversed when forming a crease.

The sheet-like materials 11 which have been creased in this manner are sequentially stacked on a storage table 19 supported below. It
5! The tray 19 is connected by a timing belt (not shown) to a deceleration motor that rotates forward and backward, and reciprocates left and right. Side walls 20 are erected on both sides of the storage table 19, and pillars 21 are arranged parallel to the side walls 20 on the outside thereof. A weight 22 is installed inside the side wall 20 so as to be able to move up and down, and forcibly lowers the fold 23 of the sheet-like material 11 that has been moving downward with the fold 23.
Its own weight holds down the ends. Above weight 22
is folded back at the upper end of the side wall 20, and the support part 2 is parallel to the column 21.
4, and a sliding body 25 that can move up and down on the support column 21 is installed at the lower end thereof. A small roller 26 is pivotally supported on the side surface of the support portion 24, and the small roller 26 runs on a trapezoidal guide rail 27 installed behind the storage table 19. The weight 22 moves up and down when the small roller 26 runs on the inclined side surface of the guide rail 27, and always applies a downward force to the sheet-like object 11 due to its own weight. Reference numeral 28 denotes a presser for the end of the sheet-like material 11, which is obtained by bending the lower end of the weight 22 horizontally.

The weight 22 is used as a guide after the press roller 15 or 16 forms a crease 23 on the sheet material 11, and before the pin 14 returns to the orthogonal state from the retreated position and begins to feed the sheet material 11 to the opposite side. It is desirable that the fold line 23 is pressed onto the storage table 19 by lowering the 1/- rule 27.

FIG. 2 shows a perspective view of the sheet-like material 11, in which both ends of electronic components 31 such as resistors or diodes are pasted and connected with a pair of adhesive tapes 32 on the front and back sides to form a continuous long sheet. . Of course, notes on each part of the device, especially each roller 1.
2, 13, 15, 16, etc. are tape portions 3, respectively.
It is necessary to clamp and crimp only 2, and it is desirable that the outer periphery be formed into a U-shaped cross section so as not to damage the electronic components, and that the upper surface crimped portion be formed of an elastic material such as rubber.

Next, FIGS. 3 to 7 show the operating principle of the folding device of the present invention in the order of steps. First, in FIG. 3, the pin 14 moves horizontally to the sheet-like material 11 that has been sent downward by the drive roller 12, and while hooking it, the drive side 17 and the pressure bonding side 18 of the press roller 15 in the open state are caught. 4), the rotary solenoid is actuated to bring the crimping side 18 into contact with the drive side 17, and the press roller 15 is further rotated in the direction of the arrow 41. At the same time, a larger loop 42 is made with the sheet-like material 11, and the pin 14 is retreated and pulled out from this loop 42 (FIG. 5). Next, the press roller 15 is reversely rotated to form a crease 23 on the folded sheet 11, and the pin 14 is returned to its original position (FIG. 6), and the press roller 15 is opened in the direction of the arrow 43 so that the pin 14 can pass through. (Figure 7).

During this time, the drive roller 12 rotates at a constant speed so that no undue load is applied to the sheet-like material 11, and the next process can be carried out immediately.

When one step is completed in this way, the above steps are repeated on the opposite side, and the sheets are alternately folded and stacked on the storage table 19, and when they reach a certain height, they are cut and the sheet-like materials 11 are taken out and boxed. Equal to

It is desirable that each of the above steps (j) be performed quickly and without malfunction by installing a photosensor on each roller and operating them sequentially.

Since the present invention is configured as described above, the sheet-like material 11 can be folded with the predetermined tli stitches 23 without stagnation or damage, so that the meander-folded sheet-like material can be manufactured with extremely high efficiency. obtain.
