JPS63154533A - Taking-out device for piled synthetic rubber - Google Patents

Abstract

PURPOSE:To take out a necessary quantity of synthetic rubber onto a conveyor connected to the next process certainly and safely by installing a means which presses a pushing tool to a calculated taking-out height from a temporary fitting tool side and pushes out the synthetic rubber. CONSTITUTION:The taking-out height of a taking-out stage is calculated from measured values and the number of stages by a calculator, and set. A table lifter 30 rises to the set taking-out height and stops. Then, a geared motor 5 normally revolves and a pressing tool 23 shifts to the taking-out side, and synthetic rubber in the front row on the highest stage is pushed out, and transferred onto the separating roller conveyors 51 and 52 through a chute 34 and a receiving roller conveyor 50, and then the synthetic rubber in the rear row is pushed out onto the chute 34 by the pressing tool 23 and then transferred onto the separating roller conveyors 51 and 52 from the receiving roller conveyor 50, and the taking-out for the synthetic rubber on the uppermost stage is completed. At the same time, the geared motor 5 revolves reversely, and the pressing tool 23 is returned to an original waiting position. When the taking- out for the uppermost stage is completed, the next lower stage forms the highest stage, and synthetic rubber is taken out in similar ways.

Concerning a take-out device for taking out and using synthetic rubber stored in piles

[1] The device used to take out synthetic rubber stacked on a vertical pallet was to pierce the synthetic rubber with a claw, lift it upwards, and transport it onto a conveyor that would transport it to the next process. However, in this kind of equipment, the synthetic rubber stacked on the pallet becomes thinner as the lower layer becomes thinner due to its own weight while being stored for a long time, as shown in Figure 5. It is deformed, and there is also close contact between the top and bottom synthetic rubber. If you pierce the thin synthetic rubber with your fingernail, it will become 2.
If you take out a layer, or if you use soft synthetic rubber, the synthetic rubber around the nail will tear under its own weight, the nail will come off, and the synthetic rubber will fall.
It was difficult to reliably and safely place the material on the conveyor for delivery to the next process because it hung down in a dogleg shape and became unstable, or it got stuck at the bottom. In addition, when stacking synthetic rubber, it is not only necessary to stack them in the same direction, but also to stack them in different directions as shown in Figure 5. In this case, the direction of the claws is changed one by one according to the direction of the synthetic rubber. Therefore, the device control becomes complicated and the device becomes expensive. In addition,
FIG. 5 shows an example of the packaging of synthetic rubber stored in piles on a pallet. Al indicates the synthetic rubber on the top tier, A3 indicates the thinner synthetic rubber on the bottom tier, A2 indicates the synthetic rubber placed with its orientation changed by 90 degrees with respect to A1, and 31a indicates a pallet. □ These problems are solved by the need to raise and lower the synthetic rubber piled up in front of the conveyor, and by installing stoppers for the lower stages other than the take-out stage, so that the overall height of the stack can be adjusted every time each stage is taken out. This can be solved by having a means for calculating the take-out height from the number of steps, and a means for pushing out the calculated take-out height by applying a pushing tool to the position of the calculated take-out height from the counter stopper. 1. For the stacked synthetic rubber, apply a push tool from the upper stage and take out the amount pushed out. When the upper stage is finished, take out the lower stage one by one. In addition, since all the steps other than the take-out stage are stopped with a stopper and a push tool is applied to the take-out stage to push it, the part that is in close contact with the synthetic rubber of the lower stage will be separated by shearing force, ensuring that the required quantity is transferred onto the conveyor leading to the next process. It can be safely removed. Furthermore, since the synthetic rubber can be taken out with a device having simple control means regardless of its long or short direction, the cost of the device is low. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 4, l indicates a device for taking out stacked synthetic rubber. 2 is a frame fixed on the floor 3, a geared motor 5 is attached to a bracket 4 fixed to the upper part of the extraction side of the frame 2, a sprocket 6 is fixed to the shaft of the geared motor 5, and is attached to the side of the frame. The sprocket 7 is connected via a chain 8 to a sprocket 7 fixed to the end of a shaft 10 rotatably mounted on a bearing 9. Sprockets 11.12 are mounted near the ends of the shaft 10. A shaft 13 is rotatably mounted on a bearing 14 mounted on the opposite side of the frame 2 at the same height from the floor parallel to the shaft 10, and a sprocket 15, 16 is fixed to the shaft 13. . In other words, sprocket) 11 becomes sprocket 15,
Sprockets 12 are connected to sprockets 16 via chains 17, 18, respectively. The chain 17 is engaged with the intermediate sprocket 19, and the chain 18 is engaged with the intermediate sprocket 20, so that the chain 1
7.18 prevents sagging. Further, a carrier 21 is attached to the chain 17, a carrier 22 is attached to the chain 18, and a pusher 23 is fixed between the carriers 21 and 22. Wheels 24 are attached to the inside of the carrier 21 via bearings, and the wheels 24 can move along guides 26. A wheel 25 is attached to the carrier 22 via a bearing inside, and the wheel 25 is attached to the guide 2.
You can move along 7. That is, the sprocket 6.7.11 from the geared motor 5
．． 12.15.16, Chain 17.18, Carrier 2
1.22, the pushing tool 23 is moved along the guide 26.27, and the pushing tool 23 constitutes extrusion means for the stacked synthetic rubber A. A stopper 28 is attached to the extraction side of the frame 2. The stopper 28 stops the stacked synthetic rubber other than the take-out stage from moving. A table lifter 30 is attached to the center of the frame 2, and synthetic rubber A stacked on pallets 31 is placed on the table lifter 30. In other words, the table lifter serves as a means for raising and lowering the stacked synthetic rubber. A photoelectric switch 32 is attached to detect the top surface of the stacked synthetic rubbers A. Reference numeral 33 denotes an encoder provided to measure the overall height of the stacked synthetic rubber each time each stage is taken out. The take-out height at which the pushing tool is applied to the synthetic rubber of the take-out stage is calculated and set by inputting the measured value of the overall height of the stacked synthetic rubber and the number of stages into a calculator (not shown). In other words, the encoder 33 and a calculator (not shown) constitute means for calculating and setting the take-out height of the stacked synthetic rubber. A chute 34 is attached to the take-out side of the frame 2. Following the chute 34, a roller conveyor 50 is arranged on a tray fixed to the floor driven by a motor (not shown). Following the roller conveyor 50, there are separate roller conveyors 51, 52 driven by respective motors (not shown) mounted on the top of the delivery heald conveyor 53; This continues to a delivery belt conveyor 53 fixed to the floor surface. Next, the operation of one embodiment of the present invention will be explained. Synthetic rubber A stacked on pallet 31 is pallet 31
The entire table is placed on a table lifter 30 using a forklift (not shown). When the table lifter 30 is raised and the upper surface of the synthetic rubber in the uppermost row hits the photoelectric switch 32, the table lifter 30 stops and the encoder 33 measures the entire height of the stacked synthetic rubber. From this measured value and the number of stages, the take-out height of the take-out stage is calculated and set by a calculator. The table lifter 30 rises to this set take-out height and stops. Next, the geared motor 5 rotates in the forward direction, and the pusher 23 moves to the ejecting side to the uppermost stage (ejecting stage).
The synthetic rubber in the front row is pushed out and moved to the chute 34, and the receiver passes through the roller conveyor 50 to the separation roller conveyor 51, 52, and the synthetic rubber in the back row is pushed out by the pushing tool 23 to the chute 34, and the receiver moves from the roller conveyor 50 to the separation roller. The process moves to conveyors 51 and 52, and the removal of the synthetic rubber on the top stage is completed. At the same time, the geared motor 5 operates in reverse rotation, and the pusher 2
3 returns to the original standby position. Separation roller conveyor 5 here
At 1.52, the synthetic rubber is separated and transferred to the delivery belt conveyor 53 and sent to the next process. When the top stage is taken out, the next stage below becomes the top stage and is taken out in exactly the same manner as described above. In this way, the lowest layer of the stacked synthetic rubber is taken out, and when the removal of the synthetic rubber stacked on one pallet is completed, the table lifter 30 descends and returns to its original position. The empty pallet is removed from the table lifter 30, and then the newly stacked synthetic rubber on the pallet is carried by a forklift and placed on the table lifter 30.
and take it out using the same procedure as above. In addition, in this invention, the operation circuit is designed to detect the beginning and end of each operation, including checking the passage of the synthetic rubber on the conveyor after being taken out, using sensors such as limit switches, proximity switches, and photoelectric switches, and perform a series of operations. All operations can be performed automatically by combining. As explained above, according to the present invention, it is possible to calculate and set the take-out height and extrude even if the stacked synthetic rubber is hard to soft, thin and deformed and tightly adhered, or oriented in different directions. The required quantity can be reliably and safely taken out from the upper stage to the lower stage, one row at a time, onto the conveyor leading to the next process. Moreover, it is a simple device and requires low equipment cost.
