Description

one

The device relates to the manufacture of reinforced concrete products on flow-conveyor lines with immediate stripping.

A device for the manufacture of concrete products, including the shape and separation board, is known.

However, since the separation board in a known device is rigidly connected to the pallet, it is not rational to use it in the production of concrete products on conveyor lines with immediate dismantling.

The purpose of the invention is to provide the possibility of immediate dismantling of products with end pins.

This is achieved by the fact that the parting board is made with a lifting-traverse, to which, with the aid of L-shaped levers, rotation-drive forming walls are pivotally attached. In this case, the drive of rotation of the forming walls is made in the form of a pair of pneumatic chambers interacting with the horizontal and vertical arms of the levers.

FIG. Figures 1 and 2 show the separation board of the device during the molding and at the time of the removal of products (in section). FIG. 3 shows a section along A - A in FIG. one.

A separating bead is installed on the molding station of a conveyor line for the manufacture of concrete products with immediate stripping and is used when two products with end keys are simultaneously molded on one pallet. The separator board contains a lifting and lowering yoke 1, on which, by means of L-shaped levers 2, the pivotal drive forming walls 3 are hingedly mounted. spool switch. The upper pneumatic chamber 5, resting on the saddle 6, interacts with the horizontal arms of the L-shaped levers 2, and the lower pneumatic chamber 4 interacts with the vertical arms through the pressure plates 7. The forming walls on the outer side have projections 8 corresponding to the shape of the keys on the ends of the product.

The device works as follows.

The pallet truck, moving along a conveyor line, enters the molding station. The lifting traverse of the separating board is lowered and the board is installed on the pallet. The air then exits the upper pneumatic chamber through the slide valve to the atmosphere, and compressed air is supplied to the lower chamber. In so doing, the forming walls are consumed and occupy a working position.

The longitudinal and transverse sides are pushed in, the concrete mix is loaded, and the molding of the two products is carried out.

At the end of the molding, the products are immediately dismantled. In order to remove the separation board from the gap between the products, it is necessary to reduce its forming walls. For this, the lower pneumatic chamber is connected to the atmosphere, and compressed air is supplied to the upper one.

In so doing, the forming walls rotate around the hinges, converge and the protrusions 8 emerge from the recesses at the ends of the molded products. Then, the separation board is freely removed from the forming zone.

Then, the longitudinal and transverse sides are diverted and the pallet-trolley enters the next post of the conveyor line.
