[0043] In a specific embodiment, the collection device provided by the present invention comprises:

[0044] Storage box 5;

[0045] The number of the material storage boxes 5 is preferably set to be more than two to achieve the transfer of the material storage boxes 5 on the collecting device.

[0046] The feeding assembly, the transfer and packing assembly 6 and the return assembly 7 are sequentially arranged on the frame. The feeding assembly and the return assembly 7 are respectively provided with a feeding lifting module 2 and a return lifting module 9 capable of lifting and lowering to switch between high and low positions;

[0047] The feed assembly, transfer and packing assembly 6, conveying assembly 8 and return assembly 7 are all conveying parts capable of conveying the storage box 5, such as a conveyor belt or other conveying devices.

[0049] The transfer and packing component 6 includes a bag pushing module 13 for pushing the workpieces in the storage box 5 for packing; the storage box 5 collects the workpieces through the feeding component, and moves to the transfer and packing component 6 for packing, then moves to a low position through the return component 7 and moves to the feeding component through the conveying component 8, and rises and rotates to a high position through the feeding component.

[0050] The bag pushing module 13 is preferably configured as a cylinder, which cooperates with the material storage box 5 to push the workpiece into the box body for packing, thereby realizing the overall packing of the workpiece.

[0051] The specific working process is as follows: a storage box 5 is placed on the feeding component and loaded with materials. The full storage box 5 is transferred to the transfer and packing component 6 for packing through the bag pushing module 13. The empty storage box 5 after packing is transferred to the return component 7, and the return component 7 is driven to descend to a low position by the return lifting module 9. The empty storage box 5 on the return component 7 moves to the conveying component 8, and the feeding component is descended to a low position through the feeding lifting module 2, and the empty storage box 5 moves to the feeding component and is driven to a high position by the feeding lifting module 2 to realize the rotation of the storage box 5. In the above process, when the storage box 5 is packed in the transfer and packing component 6, the feeding component can simultaneously convey the new storage box 5 for collection, and realize the cyclic operation by rotating the two storage boxes 5. In other embodiments, the number of storage boxes 5 can be set as needed, which is within the protection scope of the present invention.

[0052] By using the collecting device provided by the present invention, the feeding component and the return component 7 are respectively connected to the feeding lifting module 2 and the return lifting module 9, and the transfer of the storage box 5 thereon is realized through the feeding component, the transfer and packing component 6, the return component 7 and the conveying component 8.

[0055] The initial unit 1 is connected to the feed lifting module 2 to switch between high and low positions;

[0056] The collecting unit 4 is used to cooperate with the clamping tool to hold the workpieces in the storage box 5 and transport the storage box 5 to the transfer and packing assembly 6.

[0057] Similarly, the initial unit 1 and the collection unit 4 are both conveying parts, and the specific structure of the conveying parts can be set according to needs. The two are independent conveying parts. When the initial unit 1 switches between high and low positions under the drive of the feed lifting module 2, the collection unit 4 remains stationary, and the storage box 5 moves from the initial unit 1 to the collection unit 4. A manipulator or clamping tooling is provided at the collection unit 4 to load the workpiece and convey the storage box 5 to the transfer and packing assembly 6.

[0058] Furthermore, the material storage box 5 includes a U-shaped box body and a sliding wall 11 disposed at an opening on one side of the U-shaped box body, and the sliding wall 11 can move along the length direction of the U-shaped box body. This arrangement facilitates the workpiece packing in cooperation with the bag pushing module 13. The extended end of the bag pushing module 13 is disposed at the sliding wall 11 of the U-shaped box body, and the workpiece is pushed into the box body by pushing the sliding wall 11 to slide in the U-shaped box body. Sliders are disposed at both ends of the sliding wall 11, and slide rails are disposed on the two side walls of the U-shaped box body. The sliders can be pulleys.

[0059] In order to block the opening side of the material storage box 5 to prevent the workpiece from spilling, a blocking plate 3 is provided on the frame and is arranged in the vertical direction to block the opening side of the U-shaped box body. The blocking plate 3 can be arranged along the length direction of the collection unit 4 and the transfer and packaging assembly 6 to block the material storage box 5 during the collection process and the transfer and packaging process. It can be understood that the blocking plate 3 and the bag pushing module 13 are arranged opposite to each other on both sides of the transfer and packaging assembly 6.

When rotated to a preset angle, the bag pushing module 13 pushes the sliding wall 11 to move in the storage box 5 to push the workpiece out of the storage box 5 as a whole. Wherein, the rotation angle of the power delivery unit relative to the horizontal plane can be set as needed, preferably 45°.

[0065] In one embodiment, the shift plate 3 is arranged on the frame, and a clearance hole is provided on the frame for facilitating the hinge connection between the lifting cylinder and the power transmission unit, and the clearance hole is preferably a strip hole. A sliding member is provided at the bottom of the roller side plate away from the lifting drive member 10, and a sliding hole matching the sliding member is provided on the frame. The sliding member can be provided with a pulley / sliding member / protrusion and other structures, so that it is clamped in the sliding hole for sliding, and at the same time, the power transmission unit and the frame are limited to prevent the power transmission unit from being separated from the frame.

[0066] Furthermore, the power delivery unit comprises:

[0067] A plurality of groups of rollers and roller driving members connected to the rollers;

[0068] The roller drive is specifically a motor, and the structure and connection method of the roller and the roller drive can refer to the prior art. In order to fix the roller, roller side plates for fixing the roller are arranged oppositely at both ends in the length direction of the multiple groups of rollers, the lifting drive 10 and the roller side plates are hinged, and the bag pushing module 13 is arranged on the roller side plate away from the lifting drive 10. Preferably, a fixing plate 14 can be arranged on the roller side plate, and the bag pushing module 13 is installed through the fixing plate 14 to optimize the installation space.

[0069] Further, the bag pushing module 13 includes:

[0070] A bag pushing cylinder and a plane connecting block 12 arranged at the protruding end of the bag pushing cylinder, wherein the plane connecting block 12 is used to contact the sliding wall 11;

[0071] A guide sleeve 16 fixedly mounted on the side plate of the drum;

[0072] The guide rod 15 is sleeved on the guide sleeve 16 and can slide relative to the guide sleeve 16 , and the extended end of the guide rod 15 is connected to the planar connecting block 12 .

[0073] The sliding wall 11 is pushed by the bag pushing cylinder and the guide assembly.

[0074] The device is arranged in two layers, the collection unit 4 and the transfer and packing assembly 6 are located in the middle of the upper layer, and the conveying assembly 8 is below it. The initial unit 1 is located on the left side of the collection unit 4, and the return assembly 7 is located on the right side of the transfer and packing assembly 6. The collection unit 4 and the transfer and packing assembly 6 are installed with a shift plate 3 on one side, and the storage box 5 is transported between the units. Each unit includes a conveying roller, the initial unit 1 is driven by the feed lifting module 2, and the transfer and packing assembly 6 is installed with a jacking drive 10 on one side of the shift plate 3. The jacking drive 10 is hinged to the roller side plate of the conveying roller on this side, and the roller side plate opposite to the jacking drive 10 is hinged to the frame and can slide on the frame. The roller side plate is installed with a fixing plate 14, and the fixing plate 14 is installed with a bag pushing module 13.

[0075] The specific working process is as follows: the storage box 5 is transported from the initial unit 1 to the collection unit 4, at which time the U-shaped box body, the sliding wall 11 and the shift plate 3 of the storage box 5 form a soft bag collection cavity. After the storage box 5 completes the soft bag collection at the collection unit 4, the storage box 5 is transferred to the transfer and packing unit under the conveying of the roller. At the same time, the new storage box 5 is transported from the initial unit 1 to the collection unit 4. After the storage box 5 reaches the transfer and packing, the lifting cylinder drives the side plate of the roller to rise, and the side of the roller away from the lifting cylinder will move along the ground toward the lifting cylinder, so as to realize the inclination of the roller, the fixed plate 14, the bag pushing module 13, the plane connecting block 12 and the storage box 5. Then the bag pushing module 13 extends out and pushes the plane connecting block 12 to move obliquely upward. During the movement, the plane connecting block 12 contacts and acts on the sliding wall 11. The plane connecting block 12, the sliding wall 11 and the soft bag move forward under the driving of the bag pushing module 13 until the soft bag is transferred to the carton docked with the storage box 5, and the transfer is completed. Then the bag pushing module 13 drives the plane connecting block 12 and the sliding wall 11 to retract, and the sliding wall 11 is separated from the plane connecting block 12 after it is in place, and finally the lifting cylinder pulls the roller back to the horizontal position. After the transfer and packing component 6 is completed, the empty storage box 5 is conveyed by the roller to the return component 7, and the return lifting module 9 of the return component 7 drives the roller and the storage box 5 to descend to the lower layer, and the roller of the return component 7 is reversed to transfer the storage box 5 to the conveying component 8, and the conveying component 8 transfers the storage box 5 to the initial unit 1 that has returned to the low position, and finally the feed lifting module 2 drives the initial unit 1 and the storage box 5 to rise and return to the initial state, completing the action cycle.

[0076] The above-mentioned device sets the storage box 5 as a separate movable transfer container, and uses multiple groups of low-cost conveying units to make the storage box 5 a recyclable conveying unit.
