Description

one

The invention relates to the mechanization and automation of stamping production and can be used to feed flat blanks into the working area of a press.

The purpose of the invention is to improve performance.

On fig.CH shows a device, type .b; in fig., 2 - section A-A in fig. one . . ,,

The bracket 1 is fixed motionless on the fixture to the press (not shown), where, and-from-the-foot, located on the fixture table, are supplied with blanks by this device. To the bracket I fixed feed cylinder 2.

Through the axis E to the eye of the bracket 1 is fixed to the rotary tray 3. The cylinder 2 contains a hollow rod 4, in which a spring-loaded rod 5 moves, at the end of which a vacuum source 6 with a suction cup 7 is fixed. B and C through which fingers 9 and copier rollers 10 are connected with guides of II rotation tray 3. Two other opposite shoulders G and-D are connected with guide rolling pins that keep the stem 4 from turning. The rolling pin I2 is fixed to the shoulder D stationary, and the rolling pin 13 moves in the guide hole of the shoulder G of the lever 8 and is connected to the source 6 of the vacuum. Rolling pin 13 is the floor, through which air is supplied to the source 6 of the ejection vacuum source. type In addition, it is attached to the flag 14, acting on the limit switch 15.

The device works as follows.

When air is supplied to the feed cylinder 2, the rod 4 moves downward, while through the four-blade arm 8, the fingers 9 and the copy rollers 10 act on the guides 11 of the rotary tray 3, which have a radius configuration in this area. Tray 3 is rotated about the E axis of bracket 1, opening the suction cup 7 access to the stack with blanks. After turning the chute 3, the stem 4 is further moved downward until the suction cup 7 is in contact with the workpiece, while the copying is ro-6602

The plates 10 are already moving along the right side of the guide section 1 1 and the tray 3 remains stationary. The guide pins 12 and 13, moving downward together with the lever 8, prevent the rod 4 from turning relative to the vertical axis of the vacuum device 6 and do not allow the copy rollers 10 to jam.

About the guide grooves I1 of the swivel tray 3. The guide rolling pin 12 is fixed motionless to the arm D of the lever 8. The rolling pin I3 is made hollow with the possibility of supplying through

5 of the compressed air to the vacuum source 6 is fixed to it, and in the shoulder G of the lever 8 it freely moves in its guide hole. Move the rolling pin 13 in

20, the lever 8 is necessary to feed up the stack with blanks not after each removal from it of another blank, but after removal of a certain batch of blanks, the size of which

5 is limited by the stroke of the spring-loaded rod and the location of the limit switch 15 and the flag 14 attached to the rolling pin 12.

After touching the suction cup 7

0, with the workpiece, compressed air is supplied to the vacuum source 6 through the rolling pin 13. In the volume between the inner surface of the suction cup 7 with the workpiece creates a vacuum that keeps

5 last in contact with the suction cup 7. The air is then fed into the other cavity of the cylinder 2, the rod 4 together with the four-arm lever 8, the spring-loaded rod 5, the vacuum source 6 with the suction cup 7 and the workpiece rises upwards. The rotary chute 3, while the copier rollers 10 move along the straight-line section of the guides 11, remains stationary, and on the radius section turns to its original position. The flag 14 acts on the upper limit switch 5. A command is given to cut off the air supply to the vacuum source 6, the workpiece is removed from the suction cup 7, falls on the tray 3 and slides over it into the working press zone.

The proposed device allows to simplify the design, increase productivity and reliability by using a four-arm lever attached to the end.

the stem of the feed cylinder, the interactions-1 of its shoulders with the curvilinear grooves of the rotary chute, located under the bracket, the guide skalok, also interacting with the lever, one of which is fixed

to the latter, and the second is hollow with the possibility of movement in the guide hole of one of the arms of the lever and securing the vacuum source with a suction cup at the end of the spring-loaded rod.
