SU486839A1 - Device for separating flat blanks from the foot - Google Patents

Description

one

The invention relates to the automation of the processing of sheet blanks and can be used to load metallurgical and other equipment for stamping with flat blanks.

Devices for separating flat blanks from the foot are known, which contain vacuum grippers mounted on an endless flexible link located under the foot of the slide and individually actuated on the base of the device to communicate movement in the plane perpendicular to the base of the foot.

In known devices, the grippers are rigidly fixed on the flexible link, which, for separating the blanks from the foot, forces the flexible link to move in a direction perpendicular to the base of the foot, as a result of which the structure of the device is much more complicated.

The purpose of the present invention is to simplify the design of the device.

This is achieved by the fact that the individual drive is made in the form of a pressure plate moving in a direction, perpendicular to the base of the foot, interacting with vacuum grippers that are spring-loaded and mounted so as to move a relatively flexible link in the direction of movement of the pressure plate.

The drawing shows a diagram of the present invention.

The device comprises a belt conveyor 1 with split leading and driven drums, on which the conveyor belt is pulled.

Along the entire length of the web, spring-loaded vacuum suction cups 2 are evenly fixed, in the rods of which are mounted check valves, which ensure the removal of vacuum in the suction cups.

On the frame there is a mechanism for embedding 3 suction cups 2, the working body

which is a pressure plate 4 in the form of an overturned channel bar. When lowering the side ribs, the plate rests on the collar of the suction rod rods and, with further movement, moves the suction pads until it comes into contact with the sheet pack. For the horizontal movement of the suction cups, the fixed longitudinal support-guide bars 5, between which the rods of the suction cups move, are used.

To remove the vacuum, a mechanism 6 is provided, the disk of which is fixed on the shaft of the driving drum of the conveyor, and the check valve is mounted in the suction rod. For laying the foot 7 blanks provided

lifting table 8 of known construction, which is located under the conveyor along the axis of the unit.

In order to separate the sheet from the bag, the mechanism 3 is turned on, which, acting on the suction rod, moves them down until it comes into contact with the sheet pack. During the reverse movement under the action of the return springs, the sucker lifts the top sheet.

After lifting the suction cups to the original top floor: the conveyor drive with suction cups is activated to move the sheet horizontally over the bag. Each of the suction cups, while moving, leading the conveyor driving drum, contacts the mechanism 5, as a result of which the vacuum is removed, and the sheet, separated from the last suction cup, smoothly lays down on the adjacent transport mechanism (not shown in the drawing), on which it continues to move. After the back of the sheet leaves the conveyor

the rotation drive is turned off and the cycle is repeated.

Subject invention

A device for separating flat blanks from the foot, comprising grippers, in particular vacuum clamps, mounted on a movable endless flexible link located above the foot, and an individual drive for

communicating the movements in the direction, perpendicular to the base of the moans, characterized in that, in order to simplify the construction, the individual drive is made in the form of moving in the direction,

perpendicular to the base of the foot, the pressure plate interacting with the grippers, which are spring loaded and mounted so as to move a relatively flexible link in the direction of movement of the pressure

slabs.
