Abstract

PURPOSE:To separate plates one by one only by a conveyor for conveying a pile of plates and allow the plates separated one by one to be piled up again by providing a plate conveyor device, a clamping device, and an elevating device for the clamping device. CONSTITUTION:A clamping device 20 is lifted to a second plate from the lowest plate so as to clamp the second plate by a clamp opening/closing device. The clamping device 20 is further lifted to lift plates from the second plate on and to separate only the lowest plate 1 left on a conveyor 21. The conveyor 21 is then moved to convey the lowest plate out so as to separatively-deliver only the lowest plate. After completing the carry-out of the lowest plate, the clamping device 20 is lowered to put the plates from the second plate on onto the conveyor 21, and clamps are opened. With the repetition of this process, the plates can be separated one by one and sent out to the following process at the same time. Inversely, the plates separated one by one can be piled up by the reverse operation of the above-mentioned action.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] In order to send a pile of plates to the processing process one by one, the pile of plates is separated one by one, placed on conveyance equipment, and transported to the processing process. There is a need. This equipment is related to the separation equipment. In addition, since the plate materials after processing need to be combined into a certain shipping unit, it is necessary to pile up the separated plate materials again. This equipment can also perform this loading device.

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, a method for separating stacked plates one by one is to grasp one of the top plates of the stack using a clamp device that can move up and down and move horizontally. It was being transported onto a conveyor that transported it to the next process. Also, by reversing this operation, the loading device can
The clamping device grips the plates from the conveyor that conveys them one by one, and stacks them on the conveyor for the next process.

0003

[Problems to be Solved by the Invention] In the conventional device, the conveyor that conveys the piled up plates to the separating device and the conveyor that conveys the separated plates one by one are separated on the same conveyor. Since this was not possible, two conveyors were always required. For this reason, the conventional technology requires a space equal to or more than two plates to be separated.

[0004] Furthermore, since separation cannot be performed at the same location, a large moving device is required because the separation device moves the heavy plates between the stacked plates and the conveyance device after separation. . As for the operation time, due to the above-mentioned travel time, the separation time could not be shortened and separation could not be performed at high speed. Similar problems occurred because the loading equipment had similar equipment.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention is an apparatus that can separate plate materials one by one using only a conveyor for conveying a pile of plate materials. On the conveyor, the stacked plates are stopped in a separation device, leaving only the lowest plate in the pile, and the clamp device grabs the second and upper plates and lifts them upwards. Depending on the circumstances, leave one bottom plate. Next, drive the conveyor,
By sending out the bottom plate material, only one bottom plate material can be separated and sent to the next process.

[0006] Furthermore, the loading device can reverse the operation of a similar machine and pile up the plate materials one by one again.

[0007]

[Embodiment] The dividing device of the present invention is installed on both sides of a conveyor that conveys a pile of printing plates. As shown in the plan view of Figure 3, the dividing device consists of a clamp and an opening/closing cylinder that opens and closes the clamp (either a pneumatic cylinder or a hydraulic cylinder is selected depending on the weight of the plate material).
and a clamp part consisting of a clamp opening/closing guide, and an elevating device consisting of a hydraulic cylinder and an elevating guide to raise and lower the entire clamp part. Since the height from the roller to the plate material changes, it may be raised and lowered by a hydraulic cylinder that can stop in the middle or by a motor drive.

This apparatus is equipped with a clamp height measuring device shown at 10 in FIG. 5 as a method of detecting the lifting height of the clamp device, and its details are shown in FIG. 7. The rack gear 15 and the slide bearing 17 provide transportation on the slide rail 16 as rotation of the pinion gear 14,
This is read by the rotary encoder 18.

Furthermore, in order to always synchronize the lifting heights of the left and right clamp devices, racks are attached to the lifting guides as shown in Figure 6, and are connected with pinion gears, so that the lifting heights of the left and right sides are always constant. The structure is such that the clamped plate is always horizontal. Next, the operation of the clamp device of the present invention will be explained based on the drawings.

FIG. 8(a) is a diagram in which mats piled up by a conveyor are stopped by a dividing device. Next, as shown in (b), the clamping device is raised to the second plate material from the lowest plate material. As shown in FIG. 9(a), the second plate material is clamped by the clamp opening/closing device. As shown in (b), the clamping device is raised again, so that the second and subsequent plates are lifted, and only one of the bottom plates 1 is separated onto the conveyor. In FIG. 10(a), the conveyor is moved and the bottom plate is carried out, so that only one bottom plate is sent out and separated. In (b), after the bottom plate is completely unloaded, the clamp device is lowered to lower the second and subsequent plates onto the conveyor. Open the clamp in Figure 11. Next, the process returns to the operation shown in FIG. 8(a). By repeating this process, the plates can be separated one by one, and at the same time, the plates can be sent to the next process.

By performing the above operations in reverse, the plates separated one by one can be piled up in reverse.

0012

[Effects of the Invention] By using the device of the present invention, the dividing and loading device can be implemented in about half the space of the conventional one. In addition, by clamping and lifting the second plate material, the operating speed is reduced by approximately 1 compared to the conventional dividing cycle time.
It is now possible to divide with a division time of /2.
