Description

TECHNICAL FIELD

[0001] The utility model relates to a winding trolley conveying mode, in particular to a hook type trolley one-way conveyor. BACKGROUND

[0002] In the tire factory, rubber product factory and even other industries, there are generally winding devices on the production line to wind (roll up) the products (finished products) for collection and storage. The material is wound and collected on a I-beam, which is generally placed on a movable trolley. The winding trolley enters and exits the work station manually or by using a conveyor or other mechanical device. In order to improve production efficiency and reduce the labor intensity of the operators, a conveyor is generally used to convey the trolley into and out of the work station. The empty trolley enters the work station from one side of the production line, and after winding is completed, it leaves the work station from the other side of the production line.

[0003] There are various I-beam trolleys in the factory, some of which are flat on both sides or at the bottom. The trolley with flat sides or bottom can be lifted off the ground by the conveyor or AGV trolley. However, some I-beam trolleys are not flat at the bottom, and the trolley sides are also equipped with casters. The I-beam trolley cannot be conveyed by the conveyor because there is no flat place for the conveyor to lift it. Therefore, the I-beam trolley can only be manually pushed into the work station and manually pushed out of the work station. This is not conducive to improving production efficiency and reducing the labor intensity of the operators. SUMMARY

[0004] To solve the above-mentioned defects of the prior art, the utility model provides a hook type trolley one-way conveyor. The utility model conveyor does not change the structure of the I-beam trolley and uses a motor to drive a chain, which pulls a hook to hook the frame of the I-beam trolley to pull the trolley into and out of the work station.

[0023] Embodiment:

[0024] Figure 1It is a schematic view of a hook type trolley one-way conveyor, comprising two frames 1 and a cross beam 2 which constitute an I-shaped frame, the frame 1 is provided with a driving member, the driving member is provided with a mounting plate 6, a hook 7 is mounted on the mounting plate 6, and the driving member can drive the hook 7 to reciprocate along the frame 1; the middle part of the hook 7 is provided with a hinge shaft 73 and is hinged to the mounting plate 6, and the hook 7 can be flipped to the forward direction around the hinge shaft 73.

[0025] The utility model discloses a hook can be flipped to the forward direction, so that the trolley can advance beyond the hook, but cannot move to the rear, realizing the one-way conveying of the trolley.

[0026] Figure 2 It is Figure 1 The hook 7 comprises a first end 71 and a second end 72, the first end 71 and the second end 72 are integrally connected, and the hinge shaft 73 is arranged at the connecting position; the weight of the first end 71 is less than the weight of the second end 72, so that the position of the second end 72 is lower than the first end 71 in the natural state, and the working surface 75 of the first end 71 is in the vertical state.

[0027] Further comprising a limiting rod 74, the limiting rod 74 is arranged in front of the second end 72 to prevent the hook 7 from flipping to the rear.

[0028] When the trolley advances from the rear (right) to the front (left), the bottom of the trolley touches the inclined surface of the first end 71, so that the hook 7 flips, the trolley continues to advance after passing the hook, and the tail of the trolley passes the hook 7. When the trolley moves backward and touches the first end 71, the second end 72 will not flip under the block of the limiting rod 74, so as to prevent the trolley from moving backward, realizing the one-way conveying of the trolley.

[0029] The driving member comprises a driving motor 4, a chain 5 and a linear guide rail assembly, the chain 5 is arranged on the frame 1 through a chain wheel, and the driving motor 4 drives the chain 5 to reciprocate; the linear guide rail assembly comprises a linear guide rail and a sliding block, the linear guide rail is mounted on the frame 1, the mounting plate 6 is mounted on the sliding block, and the mounting plate 6 moves along the linear guide rail and is driven by the driving motor 4 and the chain 5.

[0030] Further comprising a limiting assembly 9 for limiting the position of the trolley in front, the limiting assembly 9 is arranged on a side plate 8, and the side plate 8 is fixed on the frame 1. The limiting assembly 9 adopts a pneumatic cylinder, the fixed end of the pneumatic cylinder is fixed on the side plate 8, and the driving rod of the pneumatic cylinder can penetrate through the side plate 8. Before working, the driving rod of the pneumatic cylinder is stretched out, and the trolley is prevented from continuing to advance when the trolley advances to the limiting rod. When the trolley needs to be conveyed out, the pneumatic cylinder is retracted.

[0031] The crossbeam 2 is further provided with a base 3 laid along the advancing direction. The base 3 is used for trolley walking.

[0032] Working principle:

[0033] The driving motor drives the chain wheel to rotate, and the chain straightly moves under the driving of the motor. A set of reversible hooks are installed on the mounting plate, and the hooks reciprocate with the chain under the driving of the motor. The I-beam trolley is manually or by other ways sent to the entrance of the hook trolley unidirectional conveyor. When the I-beam trolley enters the conveyor, the I-beam trolley frame will bump into the hooks. Since the hooks can be reversely rotated, the trolley can pass above the hooks without being hindered by the hooks. A cylinder-driven limiting component is arranged at the exit section of the hook trolley conveyor. When the limiting component works, a limiting stop lever is pushed out to hinder the I-beam trolley from advancing. At this time, the motor rotates (reverses) the chain to drive the hooks to move to the entrance of the conveyor. During the movement of the hooks to the entrance of the conveyor, the hooks bump into the obstacles under the I-beam trolley, and the hooks will automatically reverse. When the hooks run to the specified position or the limited position, the motor stops, and at this time, the hooks also run to the outside of the I-beam trolley frame.

[0034] When the production instruction needs the I-beam trolley to enter the coiling station, the limiting component cylinder at the exit end of the conveyor opens the stop lever. The driving motor gets the instruction to forwardly convey, and the motor drives the chain to advance. The chain hooks the trolley frame by the hooks to drag the I-beam trolley to advance. When the hooks run forward, there is a limiting stop lever on the hook component, and the hooks will not reverse under the action of the limiting stop lever. The limiting stop lever on the hook component is a one-way limiting stop, so that the hooks can hook the trolley to advance when the hooks advance. When the hooks retreat, the hooks can reverse to avoid obstacles. Under the control of the program, the motor reciprocates to drive the hooks to reciprocate through the chain, so as to realize the unidirectional feeding of the I-beam trolley into the coiling station. Similarly, a hook trolley unidirectional conveyor can be arranged at the coiling station to convey the I-beam trolley out of the station after the coiling work is completed.

[0035] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification made according to the technical essence of the present application belong to the scope of the technical scheme of the present application.
