Description

Technical Field

[0001] The present invention relates to the technical field of warehousing and logistics devices, and particularly to a high-efficiency hanging-type logistics goods stacking device. Background Art

[0002] With the rapid development of the logistics industry, the demand for the handling and stacking of goods has been increasing year by year. How to improve the efficiency of goods stacking has become a key issue in logistics operations. Currently, most goods stacking devices are floor-mounted, which are inconvenient to operate and occupy a large amount of space, making it difficult to achieve efficient logistics operations in a limited space. In addition, existing stacking devices usually cannot effectively utilize the space for stacking goods, resulting in waste of storage space and increased logistics costs. At the same time, most traditional stacking equipment is manually operated, with a low degree of automation, which easily leads to low operation efficiency and is difficult to meet the requirements of efficient logistics operations.

[0003] To solve the above problems, hanging-type goods stacking devices have gradually entered the market. Such devices stack goods through a hanging system, which can effectively utilize the vertical space and reduce the occupation of floor space. However, existing hanging-type stacking devices mainly rely on a single automated system, with inflexible operation and difficulty in adapting to the rapid stacking requirements of various different specifications of goods. At the same time, during the handling and loading / unloading processes, the stability of the goods cannot be guaranteed, easily causing the goods to topple and be damaged, affecting the safety and efficiency of logistics.

[0004] After retrieval, it is found that the prior art publication number is CN 113772413 A, which discloses a palletizing device for efficient logistics. In this solution, the bearing structure in the rotating clamping and load-bearing mechanism is rotated to be parallel to the support base, and then the connection between the load-bearing mechanism and the connection grip mechanism is deformed, so that the load-bearing mechanism protects the drive mechanism. The connection grip mechanism is used for the staff to pull. When the goods are placed on the support base and the connection grip mechanism is pulled, the support base can be moved through the clamping and load-bearing mechanism, realizing the transfer of the goods. When the device is installed on a manipulator, it can palletize the goods.

[0005] Therefore, based on the above retrieval and in combination with the existing technology, when the above solution is used, since the sizes of the goods are diverse, when clamping the goods, it is necessary to clamp and stack the goods one by one according to the size of each good, resulting in a multiple-fold increase in the operation time. Especially when dealing with a large number of goods, the overall efficiency will be significantly reduced. In addition, the clamping devices of the above solution are usually designed to handle goods of specific sizes or shapes. Therefore, when facing goods with irregular shapes and different sizes, there will be problems of ineffective clamping, resulting in unstable handling of the goods. For this reason, we propose a high-efficiency hanging-type logistics goods stacking device. Summary of the Invention

[0040] Please refer to Figure 3 , Figure 4 , Figure 5The adjusting device includes a center tube 307, which is fixedly mounted on the inner end of the adjusting shell 301. The outer surface of the adjusting shell 301 is sleeved with a connecting block 203, and the connecting block 203 is fixedly connected to the clamping shell 201. The connecting block 203 and the center tube 307 are connected by a return spring 308. Specifically, the return spring 308 has high elasticity and can clamp the goods firmly, and the adjusting shell 301 under the goods that is not moved by force can also support the bottom of the goods, further preventing the goods from falling during transportation. The front and rear ends of the connecting block 203 are rotatably mounted with movable rods 305, and the end of the movable rod 305 away from the connecting block 203 is rotatably mounted with a limit gear 306. The inner end of the adjusting shell 301 is fixedly mounted with two limit racks 304, and the limit racks 304 correspond to the limit gears 306.

[0043] See also Figure 9 , Figure 10 The display device includes a sliding block 205, which is slidably mounted on the front end of the clamping shell 201, and the stabilizing wheel 204 is rotatably connected to the sliding block 205. A wire wheel 403 is rotatably mounted on the front end of the clamping shell 201, and a traction wire 404 is wound on the outer surface of the wire wheel 403. The free end of the traction wire 404 is fixedly connected to the sliding block 205. Specifically, the wire wheel 403 and the clamping shell 201 are clamped by a torsion spring. Under the action of the elastic force of the torsion spring, the traction wire 404 is always kept in a taut state.

A rectangular anti-skid groove is provided on the outer surface of the passive belt 405, and an anti-sliding block is fixedly mounted on the outer surface of the wire wheel 403, so as to achieve better transmission of the force between the two.

[0044] The protective cover 401 is located at the center of the passive belt 405, and a bellows 402 is fixedly installed on the inner end of the protective cover 401.

A connecting ring 408 is fixedly installed on the right end of the bellows 402, and the upper end of the connecting ring 408 is fixedly connected to the inner end of the passive belt 405. When the passive belt 405 rotates, it can drive the bellows 402 to retract and expand through the connecting ring 408.

[0045] The working principle of the present invention is:

[0046] When in use, the vertical gear 101 and the horizontal gear 105 are driven to rotate by the output ends of the vertical motor 102 and the horizontal motor 104 respectively, so that the hanging shell 4 can reach the top of the designated goods, and then the left and right screws 108 are driven to rotate by the output end of the double-axis motor 107, so that the left and right clamping shells 201 move towards each other. At this time, the outer surface of the belt 202 contacts the outer surface of the goods. At this time, the belt 202 is squeezed and pushes the adjustment shell 301 away from each other.

[0047] At this time, the contact piece 302 contacts the outer surface of the cargo and is squeezed, and moves away from the cargo. The movement of the contact piece 302 drives the central rod 310 to move, and then the toggle ring 311 drives the passive plate 313 to move to the left, and the passive plate 313 drives the movable rod 305 to rotate through the driving rope 312, and then the limit gear 306 is engaged with the limit rack 304. At this time, the limit gear 306 can only rotate in one direction, thereby locking the moving direction of the adjustment shell 301, blocking the cargo and preventing it from falling;

[0048] At the same time, when the adjustment shell 301 is forced to move, the stabilizing wheel 204 and the supporting wheel 303 also move accordingly, and the sliding block 205 also moves accordingly under the moving state of the stabilizing wheel 204. During the movement of the sliding block 205, the traction line 404 is loosened and then, under the action of the torsion spring, the wire wheel 403 winds the traction line 404 around the outer surface, and the wire wheel 403 drives the passive belt 405 to rotate during the rotation, and the passive belt 405 drives the bellows 402 to contract through the connecting ring 408 during the rotation, so that the luminous strip 406 is exposed, thereby enabling the operator to clearly see the approximate volume of the current cargo and take corresponding measures;

[0049] During unloading, the driving motor 206 drives the driving wheel to rotate, so that the belt 202 also rotates, so that the goods can fall out one by one from between the two clamping shells 201. During the rotation of the belt 202, irregularly shaped goods can be corrected by the friction force therewith and unloaded in a reasonable posture.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
