Description

one

The invention relates to the mechanization of punching production and can be used for the single issue of flat blanks from the bunker.

A vacuum gripping body for single-piece delivery of flat blanks from a hopper is known, which comprises a bunker for accommodating flat blanks located on the base, having a hole in the lower part for flat blanks, slot billets arranged in the hole, made in the form of slats, driven by a drive through levers hinged to the base and a cam mechanism including a shaft and eccentrics turned 180 relative to each other.

In the upper part of the slats are made notches corresponding to the size and shape of the flat billet Cl 1. The known device has a complex structure and large dimensions. Closest to the proposed-by the combination of essential features

, and the achieved effect is a vacuum gripping organ to a device for single-piece delivery of flat blanks from a silo containing above it on the base

a vertically movable vacuum gripping body mounted on a holder and an orientation mechanism for flat blanks including rods moving horizontally relative to each other, each of which has an orienting bar mounted perpendicular to the direction of its movement

Claims (2)

20 bar. One of the side bars is hinged on the orienting bar with the possibility of oscillatory movement in the horizontal plane and provided with a vibration drive that includes a hinge mounted on the orienting bar and connected to the side plate through the spring housing with a horizontal annular groove and moving through the annular groove under the action of compressed air ball. The amplitude of oscillatory movements of the hinged bar is controlled by a mechanism for adjusting the amplitude of oscillatory movements, including adjustable stops mounted on a hinged bar, alternately interacting with a protrusion on the orienting bar 2. The well-known vacuum gripper does not provide a sufficiently reliable piece-by-piece dispensing of billets and high performance of the dispensing process. The chain of the invention is to increase the reliability and productivity of the process of single-piece dispensing of flat blanks. The goal is achieved by the fact that the vacuum gripping body contains a holder and mounted on it with the ability to move in the axial direction of the hollow tube, equipped with a sleeve fixed to the holder and fixed to the end of the hollow tube a hollow elastic tube, on the inner side of which is fixed rigid rings, one spaced apart from each other, and the floor tube is located in the sleeve. FIG. T shows a vacuum entrapped organ in section; FIG. 2, section A-A of FIG. 1. Vacuum gripping body contains mounted on the base of 1 bunker 2 for placing billets 3 in bulk, located above the bunker with the ability to move in the vertical direction along guides the holder 5 fixed in it vertically bushing 6, in which the vacuum gripper is placed with the possibility of vertical shifting an organ comprising a hollow tube 7. At the end of the tube 7, from the side of the hopper 2, there is an elastic tube 8 fixed, on the inner surface of which rigid rings E are attached one th at a distance t. The holder 5 is moved along the guides A downwards until the lower thoric of the elastic tube 8 interacts with the blanks 3. A vacuum (vacuum) is created in the cavity of the tubes 7 and 8. This static tube 8 is bent and the gap between its end and the workpieces is reduced. The tube 7 is moved upwardly in the sleeve 6. The blank 3 is pressed against the lower end of the sleeve 6 and completely closes the opening of the sleeve 6 and the elastic tube 8. Then the holder 5 is moved upwards along the guides and transported the blank 3 to the working position (not shown). The cavities of the tubes 7 and 8 are connected to the atmosphere, and the blanks are separated from the ends of the sleeve 6 and the elastic tube 8. Then the cycle is repeated. The effect of using a vacuum gripping organ is to increase the reliability and performance of the piece-by-piece dispensing process. Claims of the invention A vacuum gripping body comprising a holder and a hollow tube mounted thereon that can be moved axially, characterized in that, in order to increase the reliability of operation and increase the productivity of the piece-by-piece process, it is provided with a sleeve fixed to the holder and a tube with a hollow elastic tube, on the inside of which rigid rings are placed, spaced one from another at an equal distance, and the tube is located in the floor the street.
