SU735530A1 - Apparatus for destacking articles from bottom of stack - Google Patents

Abstract

A vertical stack of boxes (1) which contain ceramic objects is separated after firing and then transferred onto a belt conveyor (7). Whilst a pneumatic clamp cylinder assembly (10, 14, 18) retains the stack (1) with the help of two vertical rails (2), a second cylinder forces the lowest box loose so that it falls onto the belt conveyor. A second pair of pneumatic cylinders (6, 21) now moves a stop collar beneath the stack. The clamp cylinder is then retracted so that the entire stack is able to settle on the stop collar (6). At that point, the procedure is repeated for the removal of the next box.

Description

(54) DEVICE FOR DISASSEMBLY FROM BOTTOM STACKINGS OF PLATE PRODUCTS

one

The invention relates to a device for disassembling stacks of piece goods, preferably capsules for firing ceramic products.

A device for disassembling from the bottom of stacks of piece products is known, comprising a frame on which helical guides for piles are mounted, at least one drive block, a lifting and lowering table and a conveyor (I.

However, its low productivity is due to the fact that at the time of the separation of the capsule on the conveyor belts, the lift-lowering table must be in the lowered position.

In addition, when pasting capsules and with their possible combat capsules, they partially remain on the lifting table, as a result of which interference occurs during the subsequent operation.

The purpose of the invention is to increase labor productivity and reduce bo capsules.

This is achieved by the fact that the device is equipped with an engineered product with a bias means mounted on the frame and containing a spring-loaded

the block And an additional driveable clamping shoe located opposite to it at some distance, and the lifting table consists of two rotatables around the horizontal axis from separate drives of the bearing platforms between which the said conveyor is located.

FIG. 1 shows a device, side view; in fig. 2 shows section A-A in FIG. I.

The device for disassembling the bottom of the stack of stackable items, mainly capsules for firing ceramic products, contains

10, frame 1, on which fixed fixed ridges 2 and also pivotal about a vertical axis. guides 3. On the frame there is also a mechanism 4 for fixing the stack of capsules, including the pressing part 5, hingedly

15 connected with a lever 7 fixed on the axis 6, the other arm of which H1 harnirio is connected to the piston rod of the power unit 8. The pressing part 5 has three clamping pads 9, the middle of which are

20 compensations differ in the size of the spring loaded capsules. Each clamping pad is adjacent to one capsule. On the clamping part of the fixed stop 10.

Lifting-lowering table consists of two supporting platforms II, turning around the horizontal axis from the power cylinders 12 and mounted on the shoulders of the fork 13 of the lifting frame 14. Between the supporting platforms there is a conveyor 15.

The device is also equipped with a biasing means fixed to the frame and interacting with the lower product, which contains a spring-loaded shoe 16 with a stop 17 fixed on it and an additional drive clamping shoe 18 located opposite to it at some distance, mounted on a suspension bracket 19 suspended on a frame 1 and associated with the ram of the power cylinder 20.

The device works as follows

The stack of capsules to be disconnected is lowered with the aid of a gripper onto the capsules remaining in the device, the lowermost capsules being already disconnected. At this point, the caps capsule locking mechanism and the biasing means are closed and the lifting frame 14 is in its extreme upper position. The stationary vertical guides 2, as well as the guides 3 open during the loading of the capsules, serve to arrange the capsule stacks. With the beginning of the disengagement of the stack of capsules, the guides 3 are rotated into a working position, at which both the caps fixation mechanism 4 and the biasing means open. The entire capsule stack rests on pivot bearing platforms. Lifting frame 14 lowers it to the height of one capsule. After that, the fixing mechanism of the capsule capsule by pressing part 5c with clamping pads 9 presses the attachment to the fixed guides 2. Located on the pressing part 5, the stopper 10 during the working movement of the pressing part 5 releases the stop 17 of the spring-loaded pad 16, so that under the action of the spring it presses against the section capsule. At the same time, the second power cylinder 20 is turned on, the piston rod of which moves the additional driving clamping block 18 in the direction of the capsule, so that the detachable capsule is securely fixed.

Further, by the power cylinders 12, the support pads 11 are rotated to the vertical position. The separated capsule falls on the conveyor belt 15, which has so far been applied to the detachable capsule 22.

Simultaneously with the rotation of the bearing pads 11 to their vertical position, the force cylinder 20 shifts the lower capsule 22 together with the annular pad 16 to distance a, thereby separating the lower capsule from the ipabel.

As the capsule moves with the conveyor belt, the frame 14 simultaneously rises to the stack, and the support pads II again rotate to a horizontal position.

When re-opening the mechanism for fixing the stack of capsules, the stopper IQ of the pressing part 5 through the stop 17 acts so that the spring-loaded shoe 16 no longer fits onto the capsule 22. At the same time, the power cylinder 20 returns the additional driving clamping shoe 8 to the open position.

Thus, the entire capsule stacking is again placed in the supporting areas 11. Then the working cycle is repeated.

The supply of the device with a bias means and the execution of a lifting and lowering

the table in the form of two rotatable around the horizontal axis of the support platforms, between which the conveyor is located, provides an opportunity during the removal of an already separated capsule by the conveyor

To drop a new capsule, which improves the performance of the device, and also reduces the fight of the capsules.
