SU427894A1 - INSTALLATION FOR RETURN OF PALLETS - Google Patents

Description

one

The installation can be used in the manufacture of ceramic products, such as bricks, for the automatic transfer of pallets from drying cars to the receiving conveyor of the machine for cutting and laying bricks to the drying cars.

A known installation for the return of pallets, comprising a cutting machine with a receiving conveyor and a turntable for supplying drying cars, a multi-post crawler, successively installed accumulation and sliding conveyors. The return of the pallets to the machine is directly related to their separation from the products, i.e., an operation that is not directly related to cutting and stacking the products on the drying cars. Therefore, for the continuity of the production process, the installation includes additional accumulators or Copteiners with manual pallet retrofitting.

The purpose of the invention was 1 - to simplify the installation design, to separate the operations of unloading products from existing trolleys and loading, and to create a continuity of the production process of cutting and placing products on drying cars without manual labor. This is achieved by the fact that the accumulation and sliding conveyors are made with a fixing device and are installed

parallel to the direction of cutting the product in the machine. Moreover, at the beginning of the accumulation conveyor, a fork filing machine was installed and, perpendicular to it, there was a multi-colored loading mechanism, mounted with the possibility of a horizontal aspect, in the direction of the unloading dryer of the 1st trolley. A trolley with pallet grips mounted above the extensible conveyor is mounted to transport the pallets in groups in the direction of the receiving conveyor of the machine.

Pa figs. 1 shows the proposed installation in the plan; in fig. 2 is a view along arrow L in FIG. 1, the moment of capture of the ends of the pallets; in fig. 3 - the same view, the time of transportation of pallets; in fig. 4 is a view along arrow B in FIG. 1, the moment the pallets are fed to the hand conveyor; on fng 5 - section along bb in fig. 1, the moment of delivery of the next pallet; in fig. 6 is a view of the arrow G on the phpg. 1, the moment of transportation of pallets.

The installation contains a multi-pink loading mechanical mechanism / with a clamping device 2, a fork-type forklift 3, a storage conveyor 4, a sliding conveyor 5 with a fixing device 6 II a mobile trolley 7 with grippers 8. The pallets 9 are located on the shelves of the cantilevered trolleys 10.

The // machine for cutting and stacking products on the drying cars has a receiving conveyor 12 for pallets and a turntable 13 for feeding the drying cars to the loading area of the machine.

The installation works as follows.

After the next trolley 10 with pallets 9 arrives in the unloading zone, the loading mechanism 1 approaches it and the clamping device seizes the ends of the pallets, lifting them up. As the fork reducer is released, the loading mechanism transports the pallets from the drying trolley to the reducing agent and, releasing the clamping device, leaves the pallets on the reducing shelf and rolls out of the area occupied by the reducing agent. The empty trolley is fed to a pivoting carriage 13 for loading with pallets passing through the machine 11 and loading articles. The fork reducer alternately lowers the pallets onto the collection conveyor 4, and the latter transports them forward to the accumulation point. From there, the locking device delivers the pallets one by one on a sliding conveyor. As the receiving conveyor 12 is emptied, the movable trolley 7 becomes above the sliding conveyor, lowers and clamps the grippers 8, then lifts them together with the pallets, transports the trays over the receiving conveyor and, unclamping the grips 8,

y,

lowers them to the receiving conveyor. As the new pallet truck arrives, the cycle repeats.

Subject invention

A pallet return installation unit containing a cutting machine with a receiving conveyor and a turntable for supplying drying cars, a multi-shelf sinker, successively installed collecting and sliding conveyors, characterized in that in order to simplify its design and create continuity of the production process of cutting and stacking products on drying cars without the use of manual labor, storage and sliding conveyors are made with a locking device and installed parallel to the direction Assembling products in an automatic machine, where a fork lowering device is installed at the beginning of the accumulation conveyor and perpendicular to it is a multi-colored loading mechanism mounted with the possibility of horizontal movement in the direction of the drying car to be unloaded, and a pallet gripper trolley mounted with the possibility of pallet transport is installed above the expanding conveyor groups in the direction of the receiving conveyor of the machine.
