Description

one

This invention relates to machinery and loading operations when operating on metalworking equipment.

There are known devices for single-piece delivery of blanks from a stack mounted on a lifting table, with a swivel grip.

The purpose of the invention is to provide a case of contact grip with the supplied blanks.

For this, the proposed device is equipped with a cam fixed on the lifting table and kinematically connected with the rotary gripper.

FIG. 1 shows the kinematic scheme of the device described with the upper position of the grip; in fig. 2 - the same, when capturing parts.

On the device case all knots of the mechanism are fixed. The lifting table 1 is a slider with a reinforced bracket 2, where a stack of supplied parts 3 is mounted. Table 1 can reciprocate in a vertical direction 4, mounted on the device body. A copier 5- a rectangular plate with a hollow in the upper part is fixed on the lifting table.

A swivel grip 6 with devices 7 for gripping parts is located in the upper part of the body. Attached to swivel grip

lever 8 with roller 9 at the end. The roller can slide on the copier 5 and at the lower position of the lifting table 1 falls into the cavity of the copier. To drive the lifting table 1 with cam 5, the pneumatic cylinder 10 serves as a reciprocating movement. The rotary gripper 6 returns to a vertical position when roller 9 enters the groove of copier 5 with a spring I.

The stops of the supplied parts 3 are mounted on the lifting table 1. The latter is at this time in the lowest position, and the grip 6 is in the vertical position (roller 9 is placed in the groove of copier 5).

Under the action of the pneumatic cylinder 10, the lifting table 1 with the stack of parts 3 mounted on it rises, slipping along the guide 4. At the same time, together with the lifting table, the copier 5 fixed on it

which, when moving upward, pushes the roller 9 out of the groove, so that the lever 8 and the gripper 6 rotate. Upon further upward movement of the lifting table, the gripper 6 remains in a horizontal position, due to the shape of the copier 5.

When moving up the lifting table 1 at some point, the position of which depends

from the height of the foot of the supplied parts 3, the upper part abuts against the grip 6, presses

to him and the movement stops. Devices

7 grip the upper part. After this, the lifting table 1 starts to fall along with the stack of parts, and the upper part held by the gripping devices 7 remains on the gripper 6. When the lifting table 1 is further lowered, the roller 9 enters the groove of the copier 5 and the gripper with the held part is installed vertically under the action of the spring 11. The workpiece is then removed, and the cycle is repeated.

Subject invention

Device for single-piece submission of blanks from the foot mounted on the lifting table

swivel grip, tl and h ay hj. This is due to the fact that, in order to ensure reliable contact of the gripper with the supplied blanks, it is equipped with a cam fixed on the lifting table and kinematically connected with the rotary gripper.
