Description

Technical Field

[0001] This invention relates to the field of material transfer technology, and in particular to material transfer equipment. Background Technology

[0002] With the development of my country's industry, the supply chain system has become more and more complete. The components that make up a product are usually provided by multiple upstream suppliers, and then assembled at the assembly plant. The upstream suppliers pack the components in cardboard boxes and transport them to the assembly plant. Once at the assembly plant, the components are transferred from the cardboard boxes to turnover boxes.

[0003] Currently, this process is mostly done manually in the logistics warehouse of the assembly plant. During this process, workers need to perform a lot of repetitive and mechanical work such as moving goods, cutting cardboard boxes, transferring goods, and throwing cardboard boxes. Because the goods in the cardboard boxes and turnover boxes are relatively heavy, they need to bend over constantly when moving and transferring goods. The work is labor-intensive, has low production efficiency, and is accompanied by certain dangers. Summary of the Invention

[0004] Therefore, it is necessary to provide a material transfer device that can automatically complete the material transfer process, addressing the current problem of low efficiency when manually transferring materials from cardboard boxes to turnover boxes.

[0005] This application provides a material transfer device for flipping over a cardboard box with a turnover box placed upside down. The device includes a frame, on which a conveying structure and a clamping and flipping structure are mounted. The conveying structure includes a first roller assembly comprising multiple rollers, with a gap between adjacent rollers. The clamping and flipping structure includes a lifting assembly, a flipping assembly, and a clamping assembly. The flipping assembly can drive the clamping assembly to rotate, and the lifting assembly can drive the flipping assembly and the clamping assembly to rise and fall. The clamping assembly includes multiple first clamping rods corresponding to the gaps between the rollers, multiple second clamping rods corresponding to the gaps between the rollers, and a clamping drive member. The widths of the first and second clamping rods are both smaller than the gap width between the rollers. The second clamping rods are fixed to the movable end of the clamping drive member, and the clamping drive member can drive the second clamping rods to pass through the gaps between the rollers and cooperate with the first clamping rods to clamp the turnover box and the cardboard box.

[0006] In one embodiment, the diameter of the roller is greater than the gap width between two adjacent rollers, and the widths of the first clamping rod and the second clamping rod are both less than the gap width between two adjacent rollers.

[0007] In one embodiment, the material transfer device further includes a transfer structure disposed on the frame, and the transfer structure further includes a second roller assembly. The transfer structure is movable between a first station and a second station. When the transfer structure is located at the first station, the first roller assembly can transport the carton and the turnover box to the transfer structure. When the transfer structure is located at the second station, it can transport the carton and the turnover box to the second roller assembly.

[0008] In one embodiment, the first roller assembly and the second roller assembly are vertically aligned and parallel to each other, and the first station and the second station correspond to the same side of both.

[0009] In one embodiment, the transfer structure includes a transfer lifting assembly and a transfer conveying assembly. The transfer lifting assembly is used to drive the transfer conveying assembly to move between the first workstation and the second workstation, and the transfer conveying assembly is able to transport the carton to the second roller assembly.

[0010] In one embodiment, the second clamping rod includes a lifting portion that protrudes toward the first clamping rod and is capable of extending into the turnover box.

[0011] In one embodiment, the second clamping rod includes a second clamping section, a second connecting section, and a second blocking section. The second clamping section corresponds to the roller, and the second blocking section corresponds to a roller bracket for mounting the roller, with the second blocking section located on the side of the roller bracket away from the ground. The second blocking section is fixedly connected to the movable end of the clamping drive member, and the second clamping section is located on the side away from the first clamping rod relative to the second blocking section. The second connecting section connects the second clamping section and the second blocking section.

[0012] In one embodiment, the second clamping rod further includes a drive connecting section that is fixedly connected to the moving end of the clamping drive member and the second blocking section, such that the interconnected drive connecting section, the second blocking section and the second connecting section are U-shaped, and the bottom of the U-shape is close to the first clamping rod.

[0013] In one embodiment, when the end of the second blocking segment away from the first clamping rod abuts against the top of the roller support, the end of the second clamping segment near the first clamping rod is lower than or flush with the top of the roller.

[0014] In one embodiment, the clamping assembly further includes a fall arrestor fixedly connected to the first clamping rod and a fall arrestor fixedly connected to the driving end of the fall arrestor, wherein the fall arrestor is capable of driving the fall arrestor to rotate with the moving direction of the second clamping rod as the rotation center.

[0015] The aforementioned material transfer equipment, through the cooperation of rollers with gaps between them, a first clamping rod that can pass through the gaps between the rollers, and a second clamping rod, allows the material transfer equipment of this application to allow the carton to be placed on the first roller assembly during use. The carton can then be moved between the first clamping rod and the second clamping rod under the drive of the first roller assembly. At the same time, the second clamping rod can pass through the gaps between the rollers and cooperate with the first clamping rod to properly clamp the carton with the turnover box upside down. Compared with ordinary clamping structures, this reduces the step of placing the carton with the turnover box upside down between the two clamping parts, which is convenient for the design of automated production lines.

[0035] Please combine Figures 1 to 3As shown, this application first provides a material transfer device for flipping and turning over a cardboard box 1 with a turnover box 2 placed inside out. The device includes a frame 200, on which a conveying structure 300 and a clamping and flipping structure 100 are provided. The conveying structure 300 includes a first roller assembly 310, which includes a plurality of rollers 311, with a gap between adjacent rollers 311. The clamping and flipping structure 100 includes a lifting assembly 10, a flipping assembly 20, and a clamping assembly 30. The flipping assembly 20 can drive the clamping assembly 30 to rotate. The lifting assembly 10... It can drive the flipping assembly 20 and the clamping assembly 30 to rise and fall; the clamping assembly 30 includes multiple first clamping rods 31 corresponding to the gap of the roller 311, multiple second clamping rods 32 corresponding to the gap of the roller 311, and a clamping drive member 33. The width of the first clamping rods 31 and the second clamping rods 32 is smaller than the gap width of the roller 311. The second clamping rods 32 are fixed to the movable end of the clamping drive member 33. The clamping drive member 33 can drive the second clamping rods 32 through the gap of the roller 311 and cooperate with the first clamping rods 31 to clamp the turnover box 2 and the carton 1.

[0036] In the initial state, the first clamping rod 31 is located on the side away from the ground relative to the second clamping rod 32, and the second clamping rod 32 corresponding to the part of the carton 1 is located on the side of the first roller assembly 310 closer to the ground. At this time, the carton 1 with the turnover box 2 upside down can move between the first clamping rod 31 and the second clamping rod 32 under the drive of the first roller assembly 310, so as to avoid the carton 1 from colliding and interfering with the first clamping rod 31 or the second clamping rod 32 during transportation.

[0037] The specific material transfer process of the material transfer equipment in this application is as follows:

[0038] The clamping drive 33 drives the second clamping rod 32 to move closer to the first clamping rod 31, until the first clamping rod 31 and the second clamping rod 32 clamp the cardboard box 1 with the turnover box 2 upside down;

[0039] The lifting assembly 10 drives the flipping assembly 20, the clamping assembly 30, and the cardboard box 1 with the turnover box 2 inverted to move upward to the flipping station;

[0040] The flipping component 20 drives the clamping component 30 and the carton 1 with the turnover box 2 upside down to rotate 180 degrees to complete the flipping. At this time, the carton 1 is placed upside down in the turnover box 2, and the material in the carton 1 will be transferred to the turnover box 2 under the action of gravity.

[0041] The clamping drive 33 drives the second clamping rod 32 to move away from the first clamping rod 31 to release the turnover box 2 with the cardboard box 1 inside. At the same time, the lifting assembly 10 drives the flipping assembly 20, the clamping assembly 30 and the turnover box 2 with the cardboard box 1 inside to move down until the turnover box 2 is placed on the first roller assembly 310.

[0042] The material transfer device of this application utilizes the cooperation of rollers 311 with gaps between them, a first clamping rod 31 that can pass through the gaps between the rollers 311, and a second clamping rod 32. When in use, the carton 1 only needs to be placed on the first roller assembly 310. The carton 1 can then move between the first clamping rod 31 and the second clamping rod 32 under the drive of the first roller assembly 310. At the same time, the second clamping rod 32 can pass through the gaps between the rollers 311 and cooperate with the first clamping rod 31 to properly clamp the carton 1 with the turnover box 2 upside down.

[0043] It is understandable that the conveying structure 300 and the clamping component 30 of this application can cooperate with each other, so that the automatic feeding to the clamping position is achieved through the conveying structure 300 without affecting the normal operation of the clamping component 30; compared with the ordinary clamping structure, the step of placing the carton 1 with the turnover box 2 upside down between the two clamping components is reduced, which is convenient for the design of automated production lines.

[0044] In addition, the lifting component 10 drives the flipping component 20, the clamping component 30 and the carton 1 with the turnover box 2 upside down to move to the flipping station. The flipping station is a preset position. When the carton 1 moves to this position, there is a sufficient gap between the clamping flipping structure 100 and the first roller assembly 310 to avoid interference between the clamping flipping structure 100 and the first roller assembly 310 when the flipping component 20 drives the clamping component 30 and the carton 1 to rotate.

[0045] In some embodiments, the diameter of the roller 311 is greater than the gap width between two adjacent rollers 311, and the widths of the first clamping rod 31 and the second clamping rod 32 are both less than the gap width between two adjacent rollers 311.

[0046] Preferably, the diameter of the roller 311 is 50mm, the gap width between two adjacent rollers 311 is 40mm, the width of the first clamping rod 31 and the second clamping rod 32 is 30mm, and the gap width between two adjacent first clamping rods 31 or two adjacent second clamping rods 32 is 60mm.

[0047] Of course, the diameter and spacing of the rollers 311, and the width and spacing of the first clamping rod 31 and the second clamping rod 32 can be adapted according to the actual weight and size of the goods, the size of the carton 1 and the size of the turnover box 2, as long as at least two rollers 311 can be used to abut against the carton 1 with the turnover box 2 upside down.

[0048] Please combine Figure 1 as well as Figure 4As shown, in some embodiments, the material transfer device further includes a transfer structure 400 disposed on the frame 200, and the conveying structure 300 further includes a second roller assembly 320. The transfer structure 400 is movable between a first station and a second station. When the transfer structure 400 is located at the first station, the first roller assembly 310 can transport the carton 1 and the turnover box 2 to the transfer structure 400. When the transfer structure 400 is located at the second station, it can transport the carton 1 and the turnover box 2 to the second roller assembly 320.

[0049] Specifically, at the first station, the transfer structure 400 is directly opposite the first roller assembly 310; at the second station, the transfer structure 400 is directly opposite the second roller assembly 320. The transfer structure 400 includes a transfer lifting assembly 410 and a transfer conveying assembly 420. The transfer lifting assembly 410 is used to drive the transfer conveying assembly 420 to move between the first station and the second station, and the transfer conveying assembly 420 can transport the carton 1 to the second roller assembly 320.

[0050] In some embodiments, the transfer conveying assembly 420 includes a transfer sensor. When the transfer conveying assembly 420 is located at the first station and the transfer sensor detects that the transfer conveying assembly 420 is carrying a carton 1 and a turnover box 2, the transfer sensor controls the transfer lifting assembly 410 to move the transfer conveying assembly 420 to the second station. When the transfer conveying assembly 420 is located at the second station and the transfer sensor does not detect a box on the transfer conveying assembly 420, the transfer sensor controls the transfer lifting assembly 410 to move the transfer conveying assembly 420 to the first station.

[0051] Please refer to Figure 5 As shown, in some embodiments, the transfer and conveying assembly 420 includes a transfer connecting plate 421, a transfer driving component 422, a transfer transmission assembly 423, and a transfer conveyor belt 424. The transfer connecting plate 421 is fixed to the lifting end of the transfer lifting assembly 410, the transfer driving component 422 is fixed to the transfer connecting plate 421, and drives the transfer conveyor belt 424 through the transfer transmission assembly 423. The transfer conveyor belt 424 is used to move the turnover box 2 onto the transfer and conveying assembly 420 or to convey it to the second roller assembly 320.

[0052] Please refer to Figure 1 As shown, in some embodiments, the first roller assembly 310 and the second roller assembly 320 are vertically aligned and parallel to each other, and the first station and the second station correspond to the same side of both. This arrangement can utilize the vertical space of the first roller assembly 310, effectively reducing the overall volume of the material transfer equipment and the floor space occupied by the material transfer equipment.

[0053] Please refer to Figure 3As shown, in some embodiments, the second clamping rod 32 includes a lifting portion 32e that protrudes toward the first clamping rod 31, and the lifting portion 32e can extend into the turnover box 2.

[0054] In cases where the height of some cardboard boxes 1 is less than the depth of turnover box 2, the lifting part 32e can extend into turnover box 2 during the process of pushing cardboard box 1 upward, thereby further pushing cardboard box 1 upward until cardboard box 1 abuts against the inner bottom wall of turnover box 2, so that the clamping assembly 30 can be used to clamp and fix cardboard boxes 1 of different heights, increasing the versatility of the material transfer equipment of this application.

[0055] Please refer to Figure 3 As shown, in some embodiments, the second clamping rod 32 includes a second clamping section 32a, a second connecting section 32b, and a second blocking section 32c. The second clamping section 32a corresponds to the roller 311, and the second blocking section 32c corresponds to the roller bracket 312 for mounting the roller 311. The second blocking section 32c is located on the side of the roller bracket 312 away from the ground. The second blocking section 32c is fixedly connected to the movable end of the clamping drive member 33. The second clamping section 32a is located on the side away from the first clamping rod 31 relative to the second blocking section 32c. The second connecting section 32b connects the second clamping section 32a and the second blocking section 32c.

[0056] For ease of description, the cardboard box 1 and the turnover box 2 will be collectively referred to as the box body in the following text.

[0057] Since the second clamping rod 32 needs to move towards the first clamping rod 31 and away from the first roller assembly 310 during the clamping process of the second clamping rod 32, in order to avoid interference between the second clamping rod 32 and the roller support 312 of the first roller assembly 310, the second blocking section 32c corresponding to the roller support 312 needs to be located on the side of the roller support 312 away from the ground, that is, between the roller support 312 and the first clamping rod 31.

[0058] In addition, before clamping and flipping the box, the box needs to be transported between the first clamping rod 31 and the second clamping rod 32 by the first roller assembly 310. In order to avoid interference between the box and the second clamping rod 32 during the transportation process, the second clamping section 32a corresponding to the roller 311 needs to be flush with the roller 311 or located below the roller 311 in the initial state.

[0059] In this application, by setting the second clamping section 32a on the side of the second blocking section 32c away from the first clamping rod 31, and connecting the two through the second connecting section 32b, it is possible to simultaneously satisfy that the second blocking section 32c is located between the roller support 312 and the first clamping rod 31, and that in the initial state the second clamping section 32a is flush with the roller 311 or located on the lower side of the roller 311.

[0060] Please refer to Figure 3 As shown, in some embodiments, the second clamping rod 32 further includes a drive connecting section 32d that is fixedly connected to the moving end of the clamping drive member 33 and the second blocking section 32c, such that the interconnected drive connecting section 32d, the second blocking section 32c and the second connecting section 32b form a U-shape, and the bottom of the U-shape is close to the first clamping rod 31.

[0061] Understandably, the drive connection section 32d extends towards the ground so that the connection position between the second clamping rod 32 and the clamping drive member 33 is moved downward. Under the same equipment height, this increases the upward movable space of the second clamping rod 32 and increases the range of box sizes applicable to the material transfer equipment of this application.

[0062] Please combine Figures 1 to 3 As shown, in some embodiments, when the end of the second blocking section 32c away from the first clamping rod 31 abuts against the top of the roller support 312, the end of the second clamping section 32a near the first clamping rod 31 is lower than or flush with the top of the roller 311.

[0063] The end of the second blocking section 32c away from the first clamping rod 31 abuts against the top of the roller bracket 312, which is the initial state. At this time, the second clamping rod 32 is in the lowest position. By setting the end of the second clamping section 32a near the first clamping rod 31 to be lower than or flush with the top of the roller 311, it is ensured that when the first roller assembly 310 transports the box between the first clamping rod 31 and the second clamping rod 32, the box will not interfere with the second clamping rod 32.

[0064] In some embodiments, when the end of the second blocking section 32c away from the first clamping rod 31 abuts against the top of the roller support 312, the distance between the end of the second clamping section 32a near the first clamping rod 31 and the top of the roller 311 is 10mm.

[0065] At this spacing, on the one hand, the second clamping rod 32 will not interfere with the conveying structure 300 transporting the box in the initial state; on the other hand, due to the small spacing, after the material transfer work begins, the second clamping rod 32 can immediately abut against the box and complete the subsequent clamping work, thereby increasing the material transfer efficiency.

[0066] Please refer to Figure 3As shown, in some embodiments, the flipping assembly 20 includes a flipping drive 21 and a flipping plate 22 fixed to the rotating end of the flipping drive 21. The clamping drive 33 includes a clamping drive motor 33a and a second lead screw 33b. The clamping drive motor 33a is fixed to the flipping plate 22. The second lead screw 33b is rotatably connected to the flipping plate 22 in the vertical direction and is fixedly connected to the rotating end of the clamping drive motor 33a. The second lead screw 33b passes through the fixed clamping member 31, and the movable clamping member 32 is threadedly connected to the second lead screw 33b.

[0067] Please refer to Figure 3 As shown, in some embodiments, the clamping assembly 30 further includes a fall-prevention drive 34 fixedly connected to the first clamping rod 31 and a fall-prevention member 35 fixedly connected to the drive end of the fall-prevention drive 34. The fall-prevention drive 34 can drive the fall-prevention member 35 to rotate with the moving direction of the second clamping rod 32 as the rotation center.

[0068] The anti-fall drive component 34 can drive the anti-fall component 35 to rotate until it abuts against the side of the carton 1. Thus, during the flipping process where the flipping component 20 drives the carton 1 to flip through the clamping component 30, the anti-fall component 35 supports the carton 1, preventing the carton 1 and the turnover box 2 from falling during the flipping process.

[0069] Please refer to Figure 6 As shown, in some embodiments, the lifting assembly 10 includes a lifting drive 11 and a lifting plate 12 fixed to the moving end of the lifting drive 11, and a tilting drive 21 fixed to the lifting plate 12; the lifting drive 11 includes a support plate 11a, a slide rail 11b and a first lead screw shaft 11c, the support plate 11a is fixed to the frame 200, the first lead screw shaft 11c is rotatably connected to the support plate 11a and perpendicular to the ground, the first lead screw shaft 11c is threadedly connected to the lifting plate 12, the slide rail 11b is fixed to the support plate 11a and parallel to the first lead screw shaft 11c; a slider 12a that is slidably connected to the slide rail 11b is fixedly connected to the lifting plate 12 to play a guiding role and increase the lifting stability.

[0070] In some embodiments, two sensors are fixed on the support plate 11a along the vertical direction. When the lifting plate 12 is raised to the position of the upper sensor, the flipping component 20 starts to drive the clamping component 30 to flip. When the lifting plate 12 is raised to the position of the lower sensor, the material transfer device is in the initial state.

[0071] Please refer to Figure 7As shown, in some embodiments, the lifting drive component 11 further includes two first lead screw shafts 11c, a lifting motor 11d, a first coupling 11e, a lifting drive shaft 11f, and two second couplings 11g. The lifting motor 11d, the first coupling 11e, and the second couplings 11g are all fixed to the frame 200. The lifting motor 11d is connected to the lifting drive shaft 11f via the first coupling 11e. Both ends of the lifting drive shaft 11f are connected to a first lead screw shaft 11c via a second coupling 11g.

[0072] Please combine Figure 1 as well as Figure 8 As shown, in some embodiments, the conveying structure 300 further includes a blocking component 330, which corresponds to the gap of the roller 311 and is located on the side of the roller 311 closer to the ground. The blocking component 330 includes a blocking drive 331 and a blocking plate 332 fixed to the moving end of the blocking drive 331. The blocking drive 331 can drive the blocking plate 332 to protrude from the side of the roller 311 away from the ground.

[0073] The baffle plate 332 can block the carton 1 on the conveyor structure 300, so as to prevent the next carton 1 from being transported to the flipping station before the previous flipping operation is completed.

[0074] In some embodiments, the conveying structure 300 further includes two sets of blocking components 330 and two blocking sensors. The blocking sensors are used to detect whether the first roller assembly 310 corresponding to the blocking sensor has a housing. The two sets of blocking components 330 are the first blocking component and the second blocking component, respectively. The two blocking sensors are the first blocking sensor and the second blocking sensor, respectively. The four are arranged in sequence along the direction of the first roller assembly 310 approaching the clamping and flipping structure 100, in the order of first blocking component, first blocking sensor, second blocking component, and second blocking sensor. The first blocking sensor is adjacent to the first blocking component, and the second blocking sensor is adjacent to the second blocking component.
