Description

Technical Field

[0001] This invention relates to the technical field of logistics warehousing, and in particular to a multi-specification heavy-duty pallet cargo centering device. Background Technology

[0002] Logistics conveying equipment is mainly used in logistics for the transfer of goods. It is one of the essential pieces of equipment in the logistics transportation field, providing convenience for the transportation of goods. Among them, logistics pallets are horizontal platform devices used for the containerization, stacking, handling and transportation of goods and products as unit loads. During handling, some goods are placed on logistics pallets for transportation. When pallets are available in various sizes, the smallest pallet may have too large a gap with the side guide, causing the pallet to shift laterally or even create an angle in the conveying direction. Traditional side pushing or clamping to center the pallet can damage the conveying surface due to excessive friction between the pallet and the conveying surface, and it does not achieve an effective centering effect.

[0003] To address the issue of effective pallet centering during transport, CN2022228504983 proposed a pallet centering limiting device. This device employs symmetrically arranged adjusting components on both sides of the conveyor roller assembly. A drive unit changes the lateral position of the limiting components within the conveyor roller assembly, limiting the pallet's lateral movement range to between the two limiting components. The relative position of the two limiting components can be adjusted laterally according to the actual pallet model and width, enabling the neat transport of multiple pallets of the same model and batch. However, this structure still has the following shortcomings:

[0004] 1. This structure cannot adjust the pallet position in time when encountering heavy goods, which can easily damage the conveyor surface;

[0005] 2. This structure has a single function; it cannot effectively center the pallet by simply adjusting the lateral position of the two limiting components.

[0006] 3. This structure does not include a spring in the limiting component, so it cannot automatically limit the position of the tray. Summary of the Invention

[0007] The purpose of this invention is to solve the problems in the prior art and propose a multi-specification heavy-duty pallet cargo centering device. This device uses heavy-duty spring reset devices with inclined sides to rise and support pallets that have shifted laterally on the conveyor line with the assistance of a lifting platform. The springs are first deformed, and then the spring's thrust is used to overcome the pallet's friction and reset it. This allows pallets with lateral displacement to be automatically centered, which not only protects the conveyor surface but also improves the efficiency of pallet cargo transportation.

[0008] To achieve the above objectives, the present invention proposes a multi-specification heavy-duty pallet centering device, comprising a multi-specification centering device body and a cargo pallet. The multi-specification centering device body consists of a roller conveyor line, a guide and reset assembly, a lifting platform, a base assembly, a crank assembly, a lifting assembly, and a blocking assembly. The roller conveyor line is located above the multi-specification centering device body, and a guide and reset assembly is provided on the roller conveyor line. A lifting platform is provided outside the guide and reset assembly. The base assembly is located below the multi-specification centering device body, and a crank assembly is installed inside the base assembly. A lifting assembly is installed above the base assembly, and a blocking assembly is installed on one side of the lifting assembly. The cargo pallet is located on the conveying plane of the roller conveyor line.

[0009] Preferably, the roller conveyor line is installed on the inner wall of the lifting platform on both the left and right sides.

[0010] Preferably, the guide reset assembly includes a first guide rail slider assembly, a guide reset seat assembly, a roller assembly, a heavy-duty rectangular spring, a spring stop seat, a floating shaft, and a spring baffle. One side of the first guide rail slider assembly is mounted on the outer wall of the roller conveyor line, and the other side of the first guide rail slider assembly is connected to the guide reset seat assembly. A plurality of roller assemblies are arranged and mounted on the inclined surface of the guide reset seat assembly. One end of the heavy-duty rectangular spring is connected to the rear side of the inclined surface of the guide reset seat assembly, and the other end of the heavy-duty rectangular spring is connected to one side of the spring stop seat. A floating shaft is provided on the other side of the spring stop seat, and the floating shaft is tightly connected to the spring baffle.

[0011] Preferably, the base assembly includes a welded frame, a lifting rail, a lifting motor, a first sprocket, and a chain. The welded frame has a square structure. The lifting rail is fixedly installed in the middle of the welded frame. The lifting motor is installed on the lifting rail. The first sprocket is provided on the outside of the lifting motor. The lifting motor and the first sprocket are connected by a chain drive.

[0012] Preferably, the crank assembly includes a drive shaft, a bearing housing, a crank, a second sprocket, and a bearing. Both ends of the drive shaft are connected to one side of the bearing housing, the other side of the bearing housing is connected to the lower end of the crank, the upper end of the crank is connected to a lifting assembly, and a second sprocket is provided on the drive shaft, with a bearing installed inside the second sprocket.

[0013] Preferably, the lifting assembly includes a lifting welding frame, a guide plate, a lifting support, and lifting guide wheels. Several guide plates are installed above the lifting welding frame, a lifting support is provided below the lifting welding frame, and lifting guide wheels are installed at the connection between the lifting welding frame and the lifting support.

[0014] Preferably, the blocking assembly includes a cylinder, a lifting beam, a second guide rail slider assembly, a track mounting plate, and a blocking sheet metal. The upper end of the cylinder is fixedly mounted with a mounting plate by screws, and the mounting plate is installed at the center of the lifting beam. The lower end of the cylinder is connected to the welded frame in the base assembly. The left and right ends of the lifting beam are provided with second guide rail slider assemblies, which are fixedly mounted on the track mounting plate. The blocking sheet metal is installed on the lifting beam.

[0015] The beneficial effects of this invention are as follows: By adding a guide reset assembly, and using the inclined heavy-duty spring reset device within the guide reset assembly, a pallet that has shifted laterally on the conveyor line is raised with the assistance of a lifting platform. The spring is first deformed, and then the spring's thrust overcomes the pallet's friction to reset it. This allows the pallet with lateral displacement to be automatically centered. By adding a lifting motor, the motor on the lifting platform rotates, driving a chain. The chain drives a crank, causing the lifting assembly to rise, i.e., the guide reset assembly rises. During the rise, the roller assembly on the guide reset assembly contacts the side of the pallet, thereby touching the spring for timely reset, effectively achieving the centering effect. Because the guide reset seat is installed on the slider guide rail, the critical value of the pallet's lateral displacement at this time is the frictional force between the pallet and the guide rail on the slider. The reduction of the friction coefficient and frictional force allows the potential energy stored in the rectangular spring to effectively push the pallet, greatly improving work efficiency.

[0016] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

[0028] See Figure 4 The present invention discloses a multi-specification heavy pallet cargo centering device, comprising a crank assembly 6 including a drive shaft 61, a bearing seat 62, a crank 63, a second sprocket 64, and a bearing 65.

[0030] See Figure 6 This invention discloses a multi-specification heavy-duty pallet cargo centering device, comprising a blocking assembly 8 including a cylinder 81, a lifting beam 82, a second guide rail slider assembly 83, a track mounting plate 84, and a blocking sheet metal 85.

The blocking sheet metal 85 is installed on the lifting beam 82.

[0031] Working process of this invention:

[0032] This invention discloses a multi-specification heavy-duty pallet centering device. When the pallet 9 passes through the roller conveyor line 2, a photoelectric sensor detects the pallet 9, and the blocking component 8 on the main body 1 of the multi-specification centering device starts to work. The cylinder 81 pushes the lifting beam 82 installed on the second guide rail slider assembly 83, causing the blocking sheet metal 85 to rise to a high position. The pallet 9 touches the blocking sheet metal 85 during the conveying process, and the photoelectric sensor detects the pallet 9 at the end, and the conveyor line stops working. When the lifting motor 53 on the base assembly 5 rotates, it drives the chain 55, which drives the lifting component 7 to rise, that is, the guide reset component 3 also rises. During the rise, the roller assembly 33 of the guide reset component 3 contacts the side of the pallet 9. Because multiple sets of roller assemblies 33 are arranged at an angle, during the rise, the component force generated by the gravity of the pallet 9 laterally squeezes the roller assembly 33. The force is transmitted to the heavy-duty rectangular spring 34, causing the heavy-duty rectangular spring 34 to deform. At this time, the friction between the contact surface of the pallet 9 and the roller conveyor line 2 is too large, and the heavy-duty rectangular spring... The thrust of the deformed spring 34 is still insufficient to move the pallet 9. Therefore, before the contact surface of the roller conveyor 2 separates from the bottom surface of the pallet 9, that is, before the plane of the pallet 9 contacts the plane of the guide reset assembly 3, the heavy rectangular spring 34 continues to store potential energy and deform. As the guide reset assembly 3 continues to rise, until the bottom plane of the guide reset assembly 3 contacts the bottom plane of the pallet 9 and lifts the pallet 9 away from the contact surface of the roller conveyor 2, the critical value of the lateral displacement of the pallet 9 changes from the friction between the bottom surface of the pallet 9 and the contact surface of the roller conveyor 2 to the friction between the bottom surface of the pallet 9 and the guide reset assembly 3. Since the guide reset seat assembly 32 is installed on the first guide rail slider assembly 31, the critical value of the lateral displacement of the pallet 9 at this time is the friction between the pallet 9 and the guide rail on the slider. The decrease in the coefficient of friction and the friction force allows the potential energy of the heavy rectangular spring 34 to effectively push the pallet 9. The guide reset assemblies 3 on both sides push the pallet 9 simultaneously until the forces on both sides are balanced, thereby achieving the effect of centering.

[0033] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.

The reset assembly (3) includes a first guide rail slider assembly (31), a guide reset seat assembly (32), a roller assembly (33), a heavy rectangular spring (34), a spring stop seat (35), a floating shaft (36), and a spring baffle (37). One side of the first guide rail slider assembly (31) is installed on the outer wall of the roller conveyor line (2), and the other side of the first guide rail slider assembly (31) is connected to the guide reset seat assembly (32). Several roller assemblies (33) are arranged on the inclined surface of the guide reset seat assembly (32). One end of the heavy rectangular spring (34) is connected to the rear side of the inclined surface of the guide reset seat assembly (32), and the other end of the heavy rectangular spring (34) is connected to one side of the spring stop seat (35). The other side of the spring stop seat (35) is provided with a floating shaft (36), and the floating shaft (36) is tightly connected to the spring baffle (37).During operation, the roller assembly (33) of the guide reset assembly (3) contacts the side of the cargo pallet (9) during the upward movement. Because multiple sets of roller assemblies (33) are arranged at an angle, during the upward movement, the component force generated by the gravity of the cargo pallet (9) laterally squeezes the roller assembly (33), and the force is transmitted to the heavy rectangular spring (34), which can deform the heavy rectangular spring (34). At this time, the friction between the contact surface of the cargo pallet (9) and the roller conveyor line (2) is too large, and the thrust of the heavy rectangular spring (34) after deformation is not enough to push the cargo pallet (9) to move. Therefore, before the contact surface of the roller conveyor line (2) and the bottom surface of the cargo pallet (9) separate, that is, before the plane of the cargo pallet (9) contacts the plane of the guide reset assembly (3), the heavy rectangular spring (34) continues to store potential energy and deform. When the guide reset assembly (3) continues to During the ascent, the bottom plane of the guide reset assembly (3) contacts the bottom plane of the cargo pallet (9) and lifts it so that the cargo pallet (9) leaves the contact surface of the roller conveyor line (2). At this time, the critical value of the lateral displacement of the cargo pallet (9) changes from the frictional force between the bottom surface of the cargo pallet (9) and the contact surface of the roller conveyor line (2) to the frictional force between the bottom surface of the cargo pallet (9) and the guide reset assembly (3). Since the guide reset seat assembly (32) is installed on the first guide rail slider assembly (31), the critical value of the lateral displacement of the cargo pallet (9) at this time is the frictional force between the cargo pallet (9) and the guide rail on the slider. The decrease in the coefficient of friction and the frictional force allows the potential energy of the heavy rectangular spring (34) to effectively push the cargo pallet (9). The guide reset assemblies (3) on both sides push the cargo pallet (9) simultaneously until the forces on both sides are balanced, thereby achieving the effect of centering.
