Description

Technical Field

[0001] This utility model relates to the field of stacking equipment technology, and in particular to an automatic stacker. Background Technology

[0002] A stacker crane is a mechanical device used to automatically store and retrieve goods in a warehouse. It is mainly used to improve warehouse storage efficiency and goods handling speed. It saves space by stacking goods to a certain height and can automatically carry out inbound and outbound operations. Stacker cranes are commonly used in large logistics centers, warehouses, and supermarkets. In some large warehouses, stacker cranes can work in conjunction with other automated equipment, such as conveyors and robots, to form a highly efficient automated warehousing system.

[0003] Existing palletizers require conveyor belts to transport materials to the palletizer, and the height difference between the conveyor belt and the palletizer is needed to place the materials on the palletizer. For example, Chinese Patent Publication No. CN208499779U discloses "an automatic stacker", which uses hydraulics to automatically move goods and can quickly and accurately store goods by rotating them at a certain angle. The equipment is divided into a conveying part and a stacking part, and they are automatically spliced ​​during use. Using conveyor boxes, conveyor lines, support columns, shafts, protective covers, baffles and cameras, goods can be transported smoothly and at a uniform speed into the equipment with accurate positioning, reducing manual handling and quickly gathering scattered goods.

[0004] However, in actual use, the material needs to be placed on the palletizer's support device by utilizing the height difference between the conveyor belt and the palletizer. This not only increases the palletizer's floor space but also increases the installation and maintenance costs due to the additional conveyor belt. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that require the use of the height difference between the conveyor belt and the palletizer to place materials on the palletizer, which not only increases the palletizer's footprint but also raises its installation and maintenance costs. Therefore, this invention proposes an automatic palletizer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an automatic stacker machine, including a frame, a slide rail on the frame, a base plate slidably mounted on the slide rail, a support plate connected to the base plate via a lifting mechanism, a mounting plate connected to the support plate via a rotating structure, a clamping structure on the mounting plate, and a cylinder on the frame that cooperates with the base plate.

[0008] The rotating structure includes a connecting shaft fixedly mounted on the mounting plate, a bearing seat rotatably connected to the connecting shaft fixedly mounted at the lower end of the support plate, a gear ring fixedly mounted at the upper end of the mounting plate, a first motor fixedly mounted on the support plate, and an output shaft of the first motor passing through the support plate and fixedly mounted with a gear meshing with the gear ring.

[0009] Furthermore, the clamping structure includes a gripper assembly, a guide rail is fixedly mounted on the mounting plate, and a guide block corresponding to the guide rail is fixedly mounted on each gripper assembly.

[0010] Furthermore, the clamping structure also includes a second motor fixedly mounted on the mounting plate, the output shaft of the second motor being fixedly equipped with a double-ended lead screw, and each of the gripper assemblies being fixedly equipped with a nut seat that is threadedly connected to the double-ended lead screw.

[0011] Furthermore, the gripper assembly includes a support frame and grippers, and an adjustment component is provided between the support frame and the grippers.

[0012] Furthermore, the adjustment component includes a slot disposed on the support frame, a corresponding insert plate is fixedly disposed on the gripper, a positioning rod is fixedly disposed on the insert plate, and a sliding groove corresponding to the positioning rod is provided on the support frame.

[0013] Furthermore, the positioning rod is a screw and is threaded with a wing nut, the support frame is provided with a guide groove, and the gripper is fixedly provided with a guide plate that cooperates with the guide groove.

[0014] The automatic stacker proposed in this utility model has the following advantages:

[0015] In this utility model, by setting the positions of the frame, slide rail, cylinder control base plate and clamping structure, and by setting the height of the support plate and clamping structure by setting the lifting mechanism, the clamping structure can be directly lowered to clamp the material, and then the lifting mechanism can be used to control the clamping structure and the material to move upward for easy stacking. It does not require the height difference formed by the conveyor belt, which is more convenient.

[0016] Secondly, in this utility model, by setting a rotating structure to control the rotation of the mounting plate and the clamping structure, it is convenient to adjust the direction of the material and maximize the use of the stacking space. The length of the clamping claw of the clamping structure can be adjusted to adapt to materials of different sizes. Attached Figure Description
