Description

one

The invention relates to construction and can be used in conveyor production in the manufacture of hollow-core floor panels.

A device for forming articles is known, comprising a base, guide rails on which a pallet and a bar equipment are installed, equipped with vertical columns moved in the guides, and a mechanism for the vertical movement of the guide rails and bar equipment 1 made in the form of a rack-and-pinion gear 1.

However, in this device, the rack-and-pinion gear is difficult to manufacture, assemble, and more expensive to operate.

The purpose of the invention is to simplify the design and reduce labor costs in the manufacture, operation and installation.

The goal is achieved by the fact that the device for forming articles includes a base, guide rails on which a pallet and a side equipment are installed, provided with vertical racks being moved in the guides, and a mechanism for the vertical movement of the guide rails and of the side equipment, which are pivotally mounted on the base and pivoted in a vertical plane. levers and guide rails and vertical supports

The toolbars are made with lever stops, each of which is located between the guide rail stop and the rack stop.

FIG. 1 shows the proposed device in the position when the airborne equipment is raised, side view; in fig. 2 - the same, when the boarding equipment is lowered and installed on the pallet; in fig. 3 - section A-A of FIG. one.

The device consists of a boring equipment 1, a pallet 2 on wheels, guide rails 3 of the lifting mechanism 4 and levers 5 pivotally mounted on supports 6. The rig 1 has vertical posts 7 that are inserted into the guides 8 fixed to the beams of the lifting rails 3, and is supported on the ends of the levers 5 by means of the stops 9 fixed to the support posts 7.

On the rail beams 3, the stops 10 are fixed, on which the levers 5 rest in the middle part.

The device works as follows.

The pallet 2 is pre-rolled onto the guide rails 3, which are in the upper position (Fig. 1).

The levers 5 by means of the stops 9 and 10 hold the side equipment 1 in the upper extreme position above the tray 2.

When lowering the lifting rails 3, the pallet 2, the levers 5 and the landing gear 1 are lowered, and the speed of lowering of the landing gear due to the length of the lever arm protruding beyond the stop 10 is greater than the lowering speed of the rails, as a result of which the landing gear 1 pulls up and lowers the pallet 2.

From the action of possible horizontally directed efforts, the support posts 7 located in the guides 8 keep the rig 1 from the longitudinal-transverse displacements.

To move the pallet 2 with the molded product to the following technological posts, they lift the rails 3 during lifting of the lifting mechanism 4, as a result of which the rigging 1 takes up its original position.

The proposed device in comparison with the rack-and-pinion gear transmission significantly simplifies the design and reduces labor costs in the manufacture, installation and operation.
