Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a device for depositing and discharging products after cutting sheet-like materials such as carpets and films.

(Prior Art) Conventionally, a sheet-like material cutting machine cuts a sheet-like material fed at a predetermined speed into a predetermined length, but the cut sheet-like product has to be carried out. No. This sheet cutting machine is integrated with a manufacturing machine that kneads granular raw materials and passes them through rollers to form sheets. Changing the feed speed causes the thickness to change, and stopping mid-way causes dents. In any case, defective products are produced, so continuous operation is forced. Therefore, carrying out the cut sheet material requires manpower and skill. In other words, improvements are desired from the viewpoints of labor saving and prevention of defective products.

(Purpose of the invention) The present invention was made in order to solve the problems existing in the above-mentioned conventional technology, and is a product stacking and unloading device for a sheet-like material cutting machine that aims to reduce the occurrence of defective products and reduce the number of personnel. The purpose is to provide the following.

(Structure of the invention) In order to achieve the above purpose, the structure of the invention is as follows:
A clamping device that can freely move back and forth to clamp the tip of the sheet-shaped material, which is installed on the unloading side of the endless belt that conveys the sheet-shaped material cut by the cutting machine, a gripping device attached to the lower part of the clamping device, and a winder. a belt-shaped belt that is wound around a reel for winding and returning, with its tip end located on the unloading side of the endless belt, and holding the vicinity of the center of the lower surface of the sheet-like object being pulled out and conveyed by the extracting metal fitting; It is characterized by comprising a lifter disposed in front of the unloading side of the endless belt and a receiving plate placed on the lifter.

With this configuration, the cut and continuously fed sheet material is pinched by the clamping device when the leading end of the sheet material reaches the delivery side of the endless belt, and the belt-like belt is It is caught between the mouth extension metal fittings. Next, as the holding device moves, the belt-like belt also moves, and the sheet-like object is pulled out while being held near the center of the lower surface. When the sheet-like material comes above the receiving plate on the lifter, the belt-like belt is quickly rewound, and the sheet-like material falls and is deposited on the receiving plate. By repeating this process and reciprocating the clamping device, the sheets can be pulled out one by one. Once a sufficient amount of sheet material has been deposited, the entire receiving plate can be replaced.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In FIGS. 1 to 3, a sheet-like material fed as shown by arrow A is cut by a cutting machine 1 and fed on an endless belt 2 as shown by arrow B. In front of the belt conveyor consisting of the endless belt 2 and rollers 3, 3, there is provided a chain mechanism consisting of an endless chain 5 and sprockets 6, 6 whose driving source is a motor 4 which rotates in forward and reverse directions.
A clamping device 8 for clamping the tip of the sheet-like material 7 is attached to the chain 5, and a jaw ejecting metal fitting 9 is attached to the clamping device 8. Below the clamping device 8, a receiving plate 10 for receiving a sheet-like product 7 is disposed on a lifter 12. Reference numeral 10' indicates a receiving plate when the product is sufficiently deposited and taken out from the apparatus, and 10'' indicates a receiving plate to be used next to receiving plate 10.11 is a receiving plate provided on the lifter 12. A spherical roller 13 indicates a spherical roller for the receiving plate 10''. Reel 14 for unwinding and unwinding
A part of the belt-like belt 15 is wound around the belt, and the other part is always exposed outside. 16 is the strip belt 1
This is the roller that guides you in step 5. In this embodiment, there are five belts 15, each of which has a pipe 17 attached to its tip.

When the sheet material is cut by the cutting machine 1 and conveyed by the endless belt 2, the clamping device 8 moves to the left in FIG. to hold. At the same time, the gripping metal fitting 9 grips the pipe 17 of the belt-like belt 15. When the clamping device 8 clamps the sheet-like object 7, the clamping device 8 moves to the right. At the same time, the belt-like belt 15 is also unwound, resulting in a state as shown by the two-dot chain line in FIG. When the clamping device 8 moves to the right and reaches a predetermined position, the clamping device 8 releases the clamping of the sheet-like object 7. At the same time, the gripping of the pipe 17 by the gripping fitting 9 is released, and the belt-shaped belt 15 is rewound onto the unwinding and unwinding reel 14 and stands by at a predetermined position. When the clamping device 8 and the gripper 9 are released, the sheet-like material 7 falls onto the receiving plate 10 and is deposited thereon. In this case, while the holding device 8 moves to the right while holding the sheet-like object 7, the belt-like belt 15 and the pipe 17 hold the vicinity of the center of the lower surface of the sheet-like object 7, so that the sheet-like object 7 hangs down. Such a problem does not occur, and the sheet-like object 7 is accurately placed on the receiving plate 10. Hereinafter, sheet-like material 7-1
The clamping device 8 reciprocates as shown by arrow C for each sheet, and the belt-like belt 15 also moves forward and backward. Operation signals for moving the clamping device 8 to the left, clamping, moving to the right, releasing clamping, etc. are controlled by a limit switch, a phototube, etc. When the sheet-like material is deposited on the receiving plate 10, the lifter 12 is lowered together with the receiving plate 10, and the receiving plate 10 comes to the position of the receiving plate 10'. Then, the sheet-like object is conveyed together with the receiving plate 10'. In this case, the new receiving plate 10'' can be quickly inserted manually or electrically into the receiving plate 1.
Sent to position 0. Note that the receiving plate 10″ is the receiving plate 1.
When carried into the 0 position, the resin base 18 moves inward to receive it. And lifter 12
When the rises, the resin base 18 moves outward,
It is adapted to be removed from the receiving plate 10. Further, since the rollers 11 are attached to the receiving plate 10, replacement work and moving work are easy and labor can be reduced.

(Effects of the invention) As described above, the carrying-out device according to the present invention has a belt-like belt that pinches the tip of the sheet-like object with the clamping device and holds the bottom center of the sheet-like object with the gripper. Since the cut sheet-like objects are held without wrinkling when pulled out, they can be placed on the receiving plate one after another, thereby preventing the occurrence of defective products and improving productivity.
