Description

Technical Field

[0001] This application relates to the field of mechanical automation technology, and in particular to a pallet circulating conveyor with a dual-lifting architecture. Background Technology

[0002] Currently, pallet conveyors are mechanical devices used for automated handling of palletized goods. They efficiently transport various palletized goods through transmission methods such as rollers, chains, or belts, and are suitable for scenarios such as warehousing, production lines, and logistics centers. Their main types include roller conveyors, chain conveyors, and plate chain conveyors, which feature automated conveying, accumulation buffering, and sorting / merging functions. They significantly improve efficiency, save manpower, and support modular expansion.

[0003] Chinese patent CN110884833B discloses a pallet conveyor, belonging to the field of mechanical automation conveying. It includes a frame, a motor, a drive shaft, a driven shaft, several transmission sprockets, two transmission chains, a pallet assembly mounted on the transmission chains, and positioning components on both sides of the frame. The pallet assembly includes a base pallet, a floating pallet, and connecting components. The base pallet is fixedly connected to each of the chains at both ends. The floating pallet is movably mounted on the base pallet via the connecting components, and positioning blocks are provided at both ends of the floating pallet near the chains.

[0004] In related technologies, a reference pallet is fixed on a transmission chain, and a floating pallet is movably installed on the floating pallet. When the transmission chain transports the pallet assembly to a designated position, positioning components fixed on both sides of the frame position the positioning blocks fixed on the floating pallet, so that the two ends of the pallet are synchronized, ensuring that the pallet accurately transports the workpiece.

[0005] Regarding the aforementioned technologies, the inventors believe that single-layer conveyor lines occupy ground passageways, causing intersections between personnel passage and logistics paths, posing safety hazards and affecting visitor flow. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a pallet circulating conveyor with a double lifting structure, which solves the technical problem that a single-layer conveyor line occupies the ground passage, causing personnel passage and logistics path to intersect, resulting in safety hazards and affecting visitor flow.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A pallet circulating conveyor with a dual-lifting architecture includes: a frame supporting a pallet circulating conveyor, a first lifting area and a second lifting area formed on the frame, the first lifting area containing an empty pallet recovery area and a first feeding area, the second lifting area containing an empty pallet feeding area and a second feeding area, and a pedestrian passage between the first and second lifting areas; a rack correspondingly installed in the empty pallet feeding area, the empty pallet recovery area, and the first feeding area, on which pallets are placed; a lifting assembly mounted on the frame for driving the rack to lift and lower on the frame; a traversing assembly mounted on the frame for traversing the pallets; and a feeding assembly mounted on the frame for feeding the pallets.

[0009] Furthermore, the lifting assembly includes a drive shaft and a driven shaft, a conveyor belt is sleeved on the drive shaft and the driven shaft, the material rack is connected to the conveyor belt, a drive motor is installed on the frame, a first lifting gear is provided on the drive motor, a second lifting gear is provided on the drive shaft, and a conveyor chain is sleeved between the first lifting gear and the second lifting gear.

[0010] Furthermore, the transverse assembly includes a transverse frame, on which a first transverse roller and a second transverse roller are disposed, and a transverse belt is sleeved between the first transverse roller and the second transverse roller. A transverse motor is disposed on the transverse frame and is connected to the first transverse roller.

[0011] Furthermore, the material rack is equipped with a feeding motor and feeding wheels. The feeding wheels are rotatably mounted on two sets of the material rack. A feeding belt is provided between the two sets of feeding wheels. The feeding belt is sleeved on the two sets of feeding wheels. The feeding motor is connected to one of the feeding wheels.

[0012] Furthermore, the feeding assembly includes a feeding frame and a feeding cylinder. The feeding frame is located on one side of the transverse frame, and the feeding cylinder is mounted on the frame. One end of the piston rod of the feeding cylinder is connected to the feeding frame.

[0013] Furthermore, the feeding frame is provided with guide wheels, and several guide wheels are spaced apart on the feeding frame.

[0014] Furthermore, a counterweight is installed on one side of the conveyor belt, which is used to balance the weight of the material rack.

[0015] In summary, this application includes at least one of the following beneficial technical effects of a dual-lift architecture pallet circulating conveyor:

[0016] 1. In use, empty material trays are placed in the empty material tray loading area. Then, the lifting component lifts the empty material trays through the material rack, and the lateral component moves the empty material trays in the second lifting area to the first lifting area. After that, the lifting component lifts the material rack, and the empty material trays enter the empty material tray recycling area. At the same time, the material trays in the first loading area are moved from the first lifting area to the second loading area of ​​the second lifting area through the lateral component. Then, the loading component loads the pallets. During the processing, personnel pass through the pedestrian walkway to prevent the conveyor line from occupying the ground passage, causing personnel passage and logistics path to intersect, reducing safety hazards and impact on visitor flow.

[0025] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a pallet circulating conveyor with a dual-lifting architecture.

[0028] Reference Figure 1 A dual-lift pallet circulating conveyor includes a frame 1 with a first lifting zone 11 and a second lifting zone 12 formed on the frame 1, and a pedestrian walkway 13 formed between the first lifting zone 11 and the second lifting zone 12. A lifting assembly 2 and a traversing assembly 3 are installed on the frame 1. In use, a pallet containing materials is lifted in the first lifting zone 11 and then traversed to the second lifting zone 12 by the traversing assembly 3. A loading assembly 4 is installed on the frame 1 for loading the pallets. This eliminates the need for personnel to pass through the pedestrian walkway 13 during processing, preventing the conveyor line from occupying ground passageways, avoiding intersections between personnel passage and logistics paths, reducing safety hazards, and minimizing the impact on visitor flow.

[0029] Furthermore, a first lifting area 11 is formed on the left side of the frame 1, and a second lifting area 12 is formed on the right side. A pedestrian passage 13 is located between the first lifting area 11 and the second lifting area 12, and a transverse passage 14 is formed above the pedestrian passage 13 on the frame 1. The transverse passage 14 is connected to the first lifting area 11 and the second lifting area 12.

[0030] The frame 1 has an empty tray recovery area 15 and a first feeding area 16 on one side of the first lifting area 11, and an empty tray feeding area 17 and a second feeding area 18 on one side of the second lifting area 12. In use, the empty tray is placed in the empty tray feeding area 17, then the lifting component lifts the empty tray to the transverse channel 14, and then the transverse component 3 transversely moves the empty tray to the first lifting area 11. The empty tray falls into the empty tray recovery area 15, and then the transverse component 3 transports the tray in the first feeding area 16 from the first lifting area 11 to the second feeding area 18 of the second lifting area 12. The feeding component 4 feeds the tray.

[0031] Reference Figure 2Two sets of lifting components 2 are spaced apart between the first lifting area 11 and the second lifting area 12. Each lifting component 2 includes a drive shaft 21 and a driven shaft 22, which are arranged parallel to each other. Furthermore, a conveyor belt 23 is fitted between the drive shaft 21 and the driven shaft 22, and the conveyor belt 23 is vertically oriented. To improve the ease of rotation of the conveyor belt 23, a drive motor 24 is mounted on the frame 1. A first lifting gear 25 is mounted on the output shaft of the drive motor 24, and a second lifting gear 26 is mounted on the drive shaft 21. A conveyor chain 27 is positioned between the first lifting gear 25 and the second lifting gear 26, and is fitted onto the first lifting gear 25 and the second lifting gear 26. In operation, the drive motor 24 drives the first lifting gear 25 to rotate, which in turn drives the second lifting gear 26 to rotate via the conveyor belt 23. The second lifting gear 26 then drives the drive shaft 21 to rotate, which in turn drives the conveyor belt 23 to rotate.

[0032] In use, since the first lifting zone 11 lifts the tray filled with products, in order to improve the stability of the tray lifting, a counterweight 28 is provided on the conveyor belt 23. The counterweight 28 is used to balance the weight of the tray in the first lifting zone 11, so that the stability of the tray lifting is improved.

[0033] Reference Figure 3 Two sets of transverse transfer components 3 are spaced apart on the frame 1. One set of transverse transfer components 3 is used to move the material tray from the first lifting zone 11 to the second lifting zone 12, and the other set of transverse transfer components 3 moves the material tray from the second lifting zone 12 to the first lifting zone 11. The two sets of transverse transfer components 3 have the same structure and function, only the conveying direction is different. The following description focuses on one set of transverse transfer components 3.

[0034] The transverse transfer assembly 3 includes a transverse transfer frame 31, on which a first transverse transfer roller 32 and a second transverse transfer roller 33 are rotatably mounted. A transverse transfer belt 34 is sleeved between the first transverse transfer roller 32 and the second transverse transfer roller 33. A transverse transfer motor 35 is mounted on the transverse transfer frame, and the output shaft of the transverse transfer motor 35 is connected to the first conveying roller. In use, the transverse transfer motor 35 drives the first transverse transfer roller 32 to rotate, and the first transverse transfer roller 32 drives the transverse transfer belt 34 to rotate. When the material tray is placed on the transverse transfer belt 34 of the transverse transfer frame 31, the material tray is conveyed on the transverse transfer frame 31 as the transverse transfer belt 34 rotates.

[0035] Reference Figure 4Furthermore, material racks 5 are provided in the empty material tray recycling area 15, the first feeding area 16, and the empty material tray feeding area 17. During use, the material trays are placed on the material racks 5. To enable the material racks 5 to rise and fall within the first lifting area 11 and the second lifting area 12, the material trays are connected to the conveyor belt 23. As the conveyor belt 23 rotates on the frame 1, the material racks 5 rise and fall on the frame 1. In addition, the material racks 5 are equipped with a feeding motor 51 and feeding wheels 52. Two sets of feeding wheels 52 are arranged parallel to each other on the material racks 5, and a feeding belt 53 is sleeved between the two sets of feeding wheels 52. The material trays are placed on the feeding belt 53 of the material racks 5. The feeding motor 51 is mounted on the material racks 5, and the output shaft of the feeding motor 51 is connected to the feeding wheels 52. The feeding motor 51 drives the feeding wheels 52 to rotate, and as the feeding wheels 52 rotate, the material trays move on the material racks 5. When the material rack 5 moves to the same horizontal position as the transverse frame 31, the feeding motor 51 drives the feeding wheel 52 to rotate, and the feeding belt 53 drives the material tray to move towards the side closer to the transverse frame 31. Similarly, when the transverse frame 31 conveys the material tray to the material rack 5, the feeding motor 51 drives the feeding belt 53 to rotate in the opposite direction, so that the material tray can be placed on the material rack 5.

[0036] Reference Figure 5 When the tray filled with products moves to the second feeding zone 18, in order to remove the tray from the second feeding zone 18, the feeding assembly 4 includes a feeding frame 41 and a feeding cylinder 42. The feeding frame 41 is located on one side of the transverse frame 31, and the feeding cylinder 42 is vertically mounted on the frame 1. The feeding frame 41 is mounted on the piston rod of the feeding cylinder 42. In use, the feeding cylinder 42 drives the feeding frame 41 to lift the tray. Furthermore, the feeding frame 41 is provided with guide wheels 43, and several guide wheels 43 are rotatably mounted on the feeding frame 41. When the tray moves above the feeding frame 41 on the transverse frame 31, and the feeding frame 41 lifts the tray, the guide wheels 43 contact the tray, thereby improving the stability of the tray movement when the subsequent equipment grasps the tray.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
