Description
Technical Field
[0001] The utility model relates to the technical field of board stacking machines, in particular to a hanging rope guiding device for a board stacking machine. Background Art
[0002] A palletizer is a device used to stack and pile up boards, usually in industries such as wood processing and building material production. Rope guide equipment refers to a device that uses ropes or chains to guide and control the movement of the lifting mechanism. In a palletizer, the role of the rope guide equipment is to help maintain the stability and accuracy of the hook or other lifting device during movement. Equipped with rope guide equipment, palletizers can improve production efficiency, reduce manual labor, and ensure safety and accuracy during the stacking process. This equipment is widely used in places such as wood processing plants and building material production plants that require large quantities of stacked boards.
[0003] When stacking plates, the existing plate stacking machine lifts the plates by a lifting trolley to move them, and the plates are prone to shaking in the air, which can easily cause the stacked plates to tilt during stacking. There are disadvantages of poor stacking accuracy and stability. In order to meet the use requirements, a lifting rope guide device for a plate stacking machine is urgently needed.

[0013] The utility model provides a rope guide device for a stacking machine, which has the following beneficial effects:
[0014] 1. The rope guide device for a plate stacking machine has the effect of improving the accuracy and stability of lifting through the arrangement of a multi-stage hydraulic telescopic cylinder, a vertical block, a first slider, a horizontal block, a second slider, a guide block and a limit hole. When in use, the lifting trolley moves on the crossbeam in the warehouse, and lifts the plate through the hook under the main body of the lifting rope. During the lifting process, the PLC controller controls the lifting trolley and the multi-stage hydraulic telescopic cylinder to work together. As the main body of the lifting rope is retracted and released, the telescopic ends of the multi-stage hydraulic telescopic cylinder shrink synchronously, so that the vertical block and the horizontal block are located about 30 centimeters above the hook, which plays a role in limiting the main body of the lifting rope, avoiding large-scale shaking during the lifting process, and improving the stability of operation. After the plate is moved to the stacking position by the lifting trolley, when the staff finds that there is a gap between the plate and the stacking position, When the deviation is fixed, the output end of the first servo motor is controlled to rotate, so that the first slider threaded on the surface of the first screw slides in the first groove, and the first slider moves while driving the cross block to move together. With the movement of the cross block, the main body of the suspension rope is driven to move forward and backward through the guide block and the limit hole, thereby changing the front and rear position of the plate. At the same time, when the plate has a slight deviation to the left and right, the second servo motor can be controlled to drive the second screw to rotate, so that the second slider threaded on the surface of the second screw slides in the second groove, and then the guide block moves left and right, thereby facilitating a slight adjustment of the left and right position of the plate. In the subsequent stacking process, the above operation is automatically repeated, and the plate is driven to move to the corresponding position for stacking by the movement of the guide block and the limit hole, thereby achieving the purpose of improving the stacking accuracy and stability of the stacking machine.
