Description

(St) PREFERRED DEVICE FOR PACKAGE

one

The invention relates to the building materials industry, in particular to lifting devices used primarily for handling and laying a package of ceramic products without pallets.

According to the main author. St. No. a gripping device for a product package is known, comprising a carrier frame, hinged gripping levers at its ends, provided with a drive, and separating intermediate plates hinged between gripping levers. The device is equipped with an additional frame and a drive for moving it vertically relative to the supporting frame, and the intermediate plates are attached by means of a t to the additional frame l.

A disadvantage of the known device is the buildup of j. пАт ::; 1 ш .- -:

plates in the process, which reduces the reliability of the grip in the work.

The purpose of the invention is to increase reliability in operation.

This goal is achieved by the fact that, in the gripping device of the g11 attachment of the intermediate plates to the additional frame, are made in the form of hinged parallelogram suspensions.

The drawing shows the gripping

10 device with parallelogram suspensions, side view.

The device consists of a carrier frame), on which are pivotally fixed, 5 gripping levers 2 with drive 3, and intermediate plates i connected to each other and with levers 2 by chains 5. The device is equipped with an additional frame 6 with autonomous lifting 20 drive 7. Intermediate plates pivotally mounted on an additional frame 6 with the help of t g 8, made in the form of parallelogram suspensions with three moving links.

At THIS, the plate is rigidly fixed on the lower horizontal link 9. Traverses 10 are hung on chains between the plates.

The device works as follows 5 times.

In the initial position, the decompressed gripper is lowered onto a pre-assembled pottery map. At the same time, all intermediate plates k without swinging occupy a vertical plane-parallel position corresponding to the location of the gaps in the map, and levers 2 go beyond the outermost rows of products. is Under the action of the actuator 3, the gripping levers 2 move towards each other. friend and move the product to the center, capturing them with a standardized force. By c) to: OnChAnITs of the movement of gripping levers 2, the device is lifted and the layer is transferred for stacking in a bag. After the normalized movement of the levers 2 for unclamping, necessary for releasing the products, an autonomous drive 7 is turned on and an additional frame 6 with legs 8 leads the plates out of the gaps in the product map (layer). Then the levers 2 are pressed until the gaps between the p

mi products in the layer. At the end of the cycle ry-. chaga 2 take the original fully decompressed position. In conventional laying (cage) products, suspended traverses do not work. They are included in the work only with a multi-column or special load, when the whole rows of products are missing in the map, which are replaced when captured with traverses.

The proposed grip design is more reliable in operation than the known one. .
