Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, in particular to a bag stack transfer device. Background Art

[0002] The bag stack of cement packaging bags is formed by stacking bag stacks in a rotating and stacking manner. A bag stack is composed of several stacked cement packaging bags. After the bag stack is transported to the factory by a forklift, workers sequentially remove the bag stacks and neatly place them at the filling station in the factory for cement filling. Therefore, the disassembly of the bag stack and the arrangement of the bag stacks are particularly important links in the cement filling process. However, if it is completed by workers, the labor intensity is high and the efficiency is low.

[0003] Based on this, our company proposes an automatic bag stack unstacking and bag arranging system to replace manual labor to complete the disassembly of the bag stack and the arrangement of the bag stacks. In the initial design, the bag stack is placed on the bag stack feeding device, and the bag grabbing manipulator is driven by the bag grabbing robotic arm to sequentially grab the bag stacks. Specifically, when the bag grabbing manipulator grabs the bag stack, it lifts the bag stack by clamping one side of the bag stack, and then places the bag stack into the bag arranging device to complete the arrangement of the bag stack. However, in actual verification, it is found that when the bag grabbing manipulator lifts the bag stack and places it on the bag arranging device, since the bag stack is in a vertical state at this time, as Figure 2 shown in the figure, the bottom side of the bag stack will first contact the bag arranging device, resulting in an increased degree of non-uniformity of the bag stack after placement, so that the bag arranging device needs to perform multiple operations to complete bag arrangement, reducing the working efficiency. Summary of the Utility Model

[0004] In view of the above problems, an embodiment of the utility model provides a bag stack transfer device.

[0005] A bag stack transfer device provided by an embodiment of the utility model includes a hollow servo rotating platform. A steel column is vertically arranged on the hollow servo rotating platform. A transfer lifting drive mechanism is arranged on the steel column. A transfer rotating platform capable of rotating vertically is arranged on the transfer lifting drive mechanism. A transfer bag clamping manipulator is arranged on the transfer rotating platform.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows: After the bag stack is lifted by the bag-grabbing manipulator, the bag stack is moved above the transfer bag-clamping manipulator. The lifting drive mechanism drives the transfer bag-clamping manipulator to rise, so that the bag stack is placed in the middle of the transfer bag-clamping manipulator. Then, the transfer bag-clamping manipulator clamps the bag stack. The hollow servo rotating platform drives the transfer bag-clamping manipulator to rotate horizontally to the bag-aligning device station, and during the rotation, the transfer rotating platform rotates vertically to drive the transfer bag-clamping manipulator to rotate, so as to realize turning the bag stack to a horizontal state. Finally, the lifting drive mechanism drives the transfer bag-clamping manipulator to descend and horizontally place the bag stack on the bag-aligning device, ensuring the neatness during the transfer of the bag stack, thus facilitating the subsequent bag-aligning process and improving the bag-aligning efficiency.

[0007] Optionally, it further includes a linear drive mechanism, and the hollow servo rotating platform is arranged on the moving end of the linear drive mechanism.

[0008] Optionally, the linear drive mechanism includes a heavy-duty linear guide rail. A heavy-duty platform is slidably arranged on the heavy-duty linear guide rail. A heavy-duty drive electric cylinder drivingly connected to the heavy-duty platform is arranged on one side of the heavy-duty linear guide rail, and the hollow servo rotating platform is arranged on the heavy-duty platform.

[0009] Optionally, the transfer lifting drive mechanism includes a transfer lifting seat slidably sleeved on a profiled steel column and a transfer lifting drive unit for driving the transfer lifting seat to lift and lower. The transfer rotating platform is arranged on one side surface of the transfer lifting seat.

[0010] Optionally, the transfer bag-clamping manipulator includes two clamping palms hinged to the transfer rotating platform. Synchronous actions are realized between the two clamping palms through a gear transmission structure. A clamping motor drivingly connected to one of the clamping palms is further arranged on the transfer rotating platform. Description of the Drawings
