Description

Known constructions of steel sheets, designed for the piece-wise task of the sheets from the knuckle to various machines (talcifier, sorting, etc.), are cumbersome, have a difficult regulation and are unreliable in operation.

The proposed setter eliminates the use of manual labor for the pieces {- tasks of sheets from a package.

FIG. 1 shows the setter in the form; in fig. 2 - the same, side view.

A sheet of 2 is placed on the welded table / sheet. A setting roller 3 is lowered onto the package. The roller is rotated from the electric motor 4 through a text-cutting gear 5 and two pairs of bevel gears 5 and 7. The roller together with the drive box 8 and the shaft 9 can freely vertically move downwards under the action of its own weight. When rotating, the setting roller 5 at the expense of friction seizes the upper sheet and pulls it off the bag, feeding into the best rollers W of the working mask. As the package is reduced, the roller is lowered, without ceasing to press against the package under the action of its own weight. Pressing the roller against the bag is controlled by a counterweight //. To increase the friction between the roller and the sheet, the roller is covered with a layer of rubber. To hold the lower unnecessarily shifted sheets, there is an electromagnet / 2 fixed on the drive box 8 slightly below the roller and in front of it and descending simultaneously with the roller. The lower end of the shaft 9 through the ball bearing connected to the piston of the pneumatic cylinder 3.

When the setting roller is lowered, the cylinder is connected to the atmosphere and the shaft 9 together with the sliding key 14 passes through the sleeve 5, and the piston of the cylinder, in which the lower end of the shaft is inserted, freely lowers together with the latter. After the last sheet has been set E t the driving rollers of the working machine and the roller is lowered onto the table /, the electric motor 4 is turned off and the pneumatic cylinder 13 is turned on, which through the shaft 9 raises the roller to the extreme upper position, the side faces of the drive box coming out of the guides 16. Then the roller flips away from the axis of the shaft 9, making space for the installation of the next package. After installing the new package, the roller is rotated to its former position, the cylinder 13 is connected to the atmosphere and the roller is lowered onto the package by its own weight. In this case, the side faces of the drive box re-enter the guides 16. By turning on the electric motor 4, the roller is attached to the rotation and the task process leaves the working machine to repeat.

Subject invention

Roller sheet material setter, which differs from: in order to eliminate manual labor for the mechanical piecework task of sheets from a package, a rotating roller covered with rubber, which, under the action of its own weight, rests on the package, pulls off the sheets from it into the pull rollers and lowers as the packet diminishes, without interrupting contact with it and changing: pressure until the complete drawdown of the packet, in which the lower overly shifted sheets are held by the electromagnet.
