Abstract

PURPOSE:To provide an apparatus for packing stacked plate pieces transported on a conveyer in a pallet or in a case such as a wooden box in a substantially vertical posture, which can conduct a course of operations assuredly, safely and quickly. CONSTITUTION:In case of loading a pallet 68 (or a case 69) with stacked plate pieces 8, the plate pieces 8 are first transported by a conveyer 6 until they are brought into contact with a stopper 16, and then a support table 12 is turned by a cylinder 14 in such a manner that the plate pieces 8 have a substantially vertical posture. After a positioning plate 59 is turned upward by a cylinder, the positioning plate 59 is retreated to be brought into contact with the front of the plate piece by the cylinder 63. Subsequently, a fork 17 is raised by a cylinder 35 so that the plate pieces 8 are transferred onto the fork 17, the back thereof being supported by a back-up rod 44 moved by a cylinder 48. After that, the positioning plate 59 is retreated, and the fork 17 is advanced and lowered so that the plate pieces 8 are transferred onto the pallet 68.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used to sequentially pack a plurality of stacked plates, which are stacked and transported horizontally on a conveyor, into containers such as wooden boxes or pallets in a state in which they are propped up almost vertically. This invention relates to a vertical loading device for plate-shaped objects.

A pallet for stacking plate-like objects such as glass plates should have a leaning surface that is tilted several degrees to prevent the plate-like objects from collapsing, and a mounting surface that makes it easy to place the plate-like objects. It is completely horizontal. However, the angle between the mounting surface and the back of a container such as a wooden box is 90 degrees, and if the back is tilted forward by several degrees, the mounting surface will also be tilted forward and downward by the same angle. It is very difficult to automatically load plate-like objects vertically into both wooden boxes and the like.

Configure.

Further, each fork 17 is provided with a detection rod 66 which is biased to a forward protruding position, and when the detection rod 66 is pushed in, a micro switch (not shown) or other known proximity detection signal generator is activated. Configure.

Next, in order to load the laminated plate body 8 onto a container 69 such as a pallet 68 or a wooden box placed on a table 67 in front of the apparatus using the apparatus of the present invention, the following adjustments are first made.

The pallet 68#'i is placed on the platform 67 with the mounting surface horizontal and the vertical structure 70 in which the fork 17 is recessed between the cores aligned with the path of the 7 oaks 17, and the pallet front KFi is stacked vertically. Since it has a front wall 71 that tilts and supports the plate-like body 8, the traveling body 18 is first adjusted horizontally by the hydraulic cylinder 29, and then supported by the fork 17 and the row 256 of the backup rod 44, as will be described later. The upright angle of the link 42 is adjusted by the air cylinder 53 so that the stacked plate-shaped body 8 has a predetermined upright angle, for example, 80 degrees.

Further, when the container 69 is used, the container itself is tilted forward and placed on the mounting table 72, so that the mounting surface inside the container is also tilted. Therefore, the hydraulic cylinder 29 is used to tilt the traveling body 18 forward and downward so as to be parallel to the mounting surface, and at the same time, the air cylinder 53 is used to adjust the syringe 42 to the predetermined upright angle.

At the adjustment edge, the upper support surface of the support base 12Fi roller 15 is initially horizontal (ib), and the backup rod 44 is laid down below the shell support surface (FIG. 1).

(1) When the laminated plate body 8 transferred by the conveyor 6 comes into contact with the stopper 16, the conveyor 6 stops, and the hydraulic cylinder 14 shortens to rotate the support base 12.
The support stand 12 stops when the laminated plate-shaped body 8 becomes substantially vertical. When this rotation is stopped, the shear cylinder 65 is activated to rotate the positioning plate 59 upward, and then the air cylinder 63 is activated to move the positioning plate 59 backward so that it comes into contact with the front surface of the laminated plate 1.

Then, the air cylinder 35 is shortened to raise the fork 17 along the buffer material 60 of the positioning plate 59, and the laminated plate-like body 8 is transferred onto the fork 17 with its front surface aligned with the tip of the fork 17. At the same time, compressed air is injected into the bellows 40 to fix the front and rear positions of the fork 170.

Next, the air cylinder 48 is extended to rotate the backup rod 44 to a predetermined upright angle, and the rear surface of the laminated plate 8 is supported by the roller 56 .

(2) When the above operation is completed, the air cylinder 65.6
5 operates in reverse and rotates the positioning plate 59 out of the path of 7 oak 17. Next, the hydraulic cylinder 31 is extended to move the traveling body 18 forward, the fork 17 moves forward through the vertical groove 70, and the detection rod 60 is activated on the front wall 71 of the pallet or the laminated plate-shaped body 8a already stacked on the pallet 6B. When the loading and unloading position corresponding to 1 is reached, the detection signal is generated and the traveling body 18 is stopped, and at the same time, the air cylinder 35 is operated in reverse to lower the fork 17, and the laminated plate body 8 is moved from the fork 17 to the pallet 68. Translated above. Then, the air cylinder 55 is extended, and the backup rod 44 is tilted forward together with the link 42, so that the laminated plate-like body 8 is allowed to lean against the front wall 71 or the laminated plate-like body 8a without any gap. Note that the support stand 12Fi returns to the original position while the traveling body 1B is moving forward.

(3) After the above-mentioned standing of the laminated plate-shaped body 8 is completed, the air cylinders 48 and 55 are shortened to return the backup rod 44 and the link 42 to their original positions. Next, hydraulic pressure-IV cylinder 31
The traveling body 18 is moved backward to return the fork 17 to its original position, the bellows 40 is vented to release the fork 17, and the spring 39 returns it to its original position.

Even when the container 69 is used, stacking is performed in the order of operations (1) to (3). However, the vertical and horizontal directions 70a into which the main fork 17 enters are provided on the mounting surface of the container 69.

The above (3) operations are repeated to stack the laminated plate bodies 8 on the pallet 68 or the container 69 continuously.The control device for repeating the above sequential operations is a limit switch, Since it can be easily assembled with a well-known circuit configuration using ordinary equipment such as relays, a detailed explanation thereof will be omitted.

The present invention has the above-mentioned configuration, and allows laminated plate bodies to be stacked vertically on either pallets or containers, and moreover, because of the suppression of the backup rods, no gaps are created between the laminated plate bodies, ensuring safety and security. This has the effect of allowing quick accumulation.

Note that as the drive source in the present invention, in addition to a hydraulic cylinder and an air cylinder, various known actuators and electric motors can be used.
