Abstract

The grip, comprising a system of two pivotally connected levers with clamps, characterized in that it is equipped with a latch designed to hold the levers in a closed state and configured to go into an inoperative position, a spring designed to bring the grip into an open state and hold it in this state as well as an adjustable clamp.

Description

The utility model relates to frictional tick grippers.

Known frictional eccentric grip, consisting of a frame with a stop and pivotally mounted on the frame of an eccentric (Aleksandrov M.P. Lifting transport machines: Textbook for machine-building special universities - 6th ed., Revised. - M.: Higher school 1985.-520m., Ill.)

The disadvantage of this capture is the need to exert effort when releasing the cargo.

The closest known one is a friction tick-borne grip, consisting of two pivotally connected levers with clamps (stops) (Alexandrov M.P. Lifting transport machines: Textbook for machine-building special universities - 6th ed., Revised .- M .: Higher.pzh., 1985.- 520 m., Ill.).

The disadvantage of this capture is the impossibility of securing it on a fixed load with the condition of subsequent automatic release of the cargo at the end of its transportation.

The purpose of the utility model is to provide the possibility of securing the capture on a fixed load with the condition of the subsequent automatic release of the cargo on the environment. ..eto

 b: .fl. designed to hold the levers in a closed state and made with the possibility of transitioning into an inoperative position, by a spring designed to bring the gripper into an open state and hold it in this state as well as an adjustable clamp.

Thus, the totality of the existing features set forth in the utility model formula allows achieving the required technical result, namely, securing the capture on a fixed load with the condition of automatic release of cargo at the end of its transportation.

Figure 1 shows the capture, figure 2 shows a device for feeding bags to a conveyor belt, figure 3 shows a diagram of the operation of the capture.

The grip (figure 1) consists of two pivotally connected levers 1 and 2, respectively equipped with an adjustable clamp 3 and a rigidly flanged clamp 4, a lock 5 with a stop pivotally connected to the lever 2, a tension spring 6, which is fixed on the lever 2 on one side and, on the other hand, on the latch 5, compression springs 7, mounted on levers 1 and 2; flexible element 8 capture is connected to the drive.

The capture can work as part of a bag feeding device, packaged with bulk product, onto a conveyor belt.

The device for supplying bags to the conveyor belt (figure 2), consists of a gripper I, a drive 2 mounted on a rack 3, which is mounted on a conveyor belt 4; position 5 in figure 2 indicates the load (bag, packed with bulk product).

Capture works as follows.

during operation, the capture successively occupies three positions (Fig.Z).

The operator servicing the conveyor belt fixes the gripper to a fixed load (bag) 9, for which he brings levers 1 and 2 (Fig. 3) to the load, puts the latch 5 in the working position, while the spring 6 comes into a stretched state, and the spring 7 is compressed . In the working position, the latch 5 will be held due to the fact that the friction force between the stop of the latch 5 and the lever 1 is greater than the compression force of the spring 6, the gripper occupies position 1 (FIG. 2, FIG. 3).

After that, the operator turns on the drive motor and the engine - flexible element - gripper - load system moves. In the process of movement, the levers I and 2 (FIG. 3) are additionally compressed - this is possible due to the adjustable clamp 3, as a result of which the stop of the latch 5 ceases to contact the lever 1 and, under the action of the spring 6, the latch 5 goes into the inoperative position. The capture comes in position P (Fig.Z).

The gripper continues to pull the load to the conveyor belt with a speed lower than the flying speed. As soon as the load arrives on the belt, its speed becomes equal to the speed of the conveyor belt, as a result, the tension of the flexible element 8 (Fig. 3) is weakened and under the action of the expanding spring 7, the gripper comes into open state - position W (Fig. 2, Fig. H)

The freed cargo continues its movement along the conveyor, and the gripper is returned using a flexible element wound around the drum. The duty cycle can then be repeated again.

Claims (1)
