Description

Technical Field

[0001] This utility model relates to an automatic tray loading and unloading device, belonging to the technical field of conveying equipment. Background Technology

[0002] Currently, multiple trays are placed vertically on the shelves. After materials are placed in the trays, they are placed on the shelves, and then the shelves are moved into the oven for baking. However, placing the trays on the shelves is currently done manually, resulting in high labor intensity and low efficiency. Utility Model Content

[0003] This invention provides an automatic tray loading and unloading device, which solves the problem that manual tray loading on shelves is labor-intensive and inefficient.

[0004] This utility model relates to an automatic tray loading and unloading device, including a conveyor for transporting trays, a shelf for placing multiple trays vertically next to the conveyor, a tray arrangement mechanism for transporting and placing trays onto the shelf next to the shelf, and a vertical circulation lifting mechanism for transferring and transporting the trays onto the unloading mechanism next to the conveyor.

[0005] As a preferred embodiment, the vertical circulating lifting mechanism includes a housing with an annular circulating chute on the side facing the conveyor. Multiple circulating sliders are provided inside the circulating chute. A horizontal bracket is fixed to the outside of the circulating slider to receive the pallet delivered by the conveyor. The circulating slider is connected to a circulating drive mechanism. The circulating slider slides in the circulating chute, which can drive the horizontal bracket to receive the pallet delivered by the conveyor and then lift and transfer it to the sculpting mechanism.

[0006] As a preferred embodiment, the circulating drive mechanism includes circulating sprockets rotatably mounted inside a housing and disposed on the inner sides of the upper and lower ends of the circulating slide groove. A circulating chain connects the upper and lower circulating sprockets. One of the circulating sprockets is connected to a circulating drive motor. Circulating sliders are fixed to the circulating chain. Each circulating slider has a rotating shaft rotatably mounted on it. The outer end of the rotating shaft is fixed to a horizontal bracket, and the inner end of the rotating shaft is connected to a horizontal holding mechanism. The circulating drive motor drives the circulating sprockets to rotate, thereby driving the circulating chain to rotate, which in turn causes the circulating sliders to circulate and slide within the circulating slide groove.

[0007] As a preferred embodiment, the horizontal holding mechanism includes a horizontal frame plate and a vertical frame plate fixed to a rotating shaft. Horizontal limit wheels are rotatably mounted at both ends of the horizontal frame plate, and vertical limit wheels are rotatably mounted at both ends of the vertical frame plate. The two horizontal limit wheels are located on opposite sides of the horizontal frame plate, and the two vertical limit wheels are located on opposite sides of the vertical frame plate. Two mounting plates (first and second) are fixed inside the outer casing. Mounting plates (first) are each provided with a limiting slide rail (first) to guide the left and right horizontal limit wheels, and mounting plates (second) are each provided with a limiting slide rail (second) to guide the up and down vertical limit wheels. The arrangement of the horizontal and vertical limit wheels, limiting slide rails (first and second) ensures that the rotating shaft does not rotate when the circulating slider turns, thus keeping the horizontal support in a horizontal state and preventing the tray from falling.

[0008] As a preferred embodiment, the rack includes a mobile frame with a placement rack fixed to the top. The placement rack has an inlet on the side facing the vertical circulating lifting mechanism. Multiple pairs of trays are provided on the inner side wall of the placement rack in the vertical direction to facilitate the placement of pallets. The trays can support the outer edge of the pallets.

[0009] As a preferred option, the rack is equipped with limit rods on both sides, with L-shaped hanging rods fixed on the limit rods. The rack is also equipped with a hanging plate, which has hanging holes for the outer ends of the hanging rods to be inserted, preventing the pallets from falling off when the rack is moved.

[0010] As a preferred embodiment, the palletizing mechanism includes a lifting mechanism with a lifting frame installed on it. The horizontal support has multiple clearance slots, and multiple lever plates that pass through the clearance slots are fixed on the lifting frame. Each lever plate is rotatably mounted with a pallet-swinging conveyor belt, the outer end of which extends into the shelf. When the vertical circulating lifting mechanism lifts and transfers the pallet, the lever plate can catch the pallet falling from above, and then the pallet is transported to the shelf for placement via the pallet-swinging conveyor belt.

[0011] As a preferred embodiment, the lifting mechanism includes a lifting frame plate, on which a linear guide rail module is provided, and a lever arm plate is mounted on the linear guide rail module.

[0012] This utility model has the following beneficial effects:

[0013] It can automatically transport and place pallets containing materials onto shelves, resulting in a higher degree of automation, improved efficiency in pallet placement, and reduced labor intensity. Attached Figure Description

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1, such as Figures 1 to 12As shown, this utility model is an automatic tray loading and arranging device, including a conveyor 1 for conveying trays, a shelf for placing multiple trays in a vertical direction next to the conveyor 1, a tray arranging mechanism for conveying and arranging trays onto the shelf, and a vertical circulating lifting mechanism for transferring and conveying the trays on the conveyor 1 to the arranging mechanism.

[0029] During operation, the shelf is moved to the tray placement position, and then conveyor 1 sends the pallet filled with materials to the vertical circulation lifting mechanism. The vertical circulation lifting mechanism then transports the pallet to the tray arrangement mechanism, which then transports the pallet to the shelf for tray placement.

[0030] In Example 2, based on Example 1, the vertical circulating lifting mechanism includes a housing 9. The housing 9 has an annular circulating chute 10 on the side facing the conveyor 1. The circulating chute 10 has multiple circulating sliders 11. A horizontal bracket 12 is fixed on the outside of the circulating slider 11 to receive the pallet conveyed by the conveyor 1. The circulating slider 11 is connected to a circulating drive mechanism.

[0031] The circulating drive mechanism includes circulating sprockets 18 rotatably mounted inside the housing 9 on the inner side of the upper and lower ends of the circulating slide 10. A circulating chain is connected between the upper and lower circulating sprockets 18. One of the circulating sprockets 18 is connected to a circulating drive motor. Circulating sliders 11 are fixed on the circulating chain. Each circulating slider 11 is rotatably mounted with a rotating shaft 20. The outer end of the rotating shaft 20 is fixed to the horizontal bracket 12, and the inner end of the rotating shaft 20 is connected to a horizontal holding mechanism.

[0032] The horizontal holding mechanism includes a horizontal frame plate 21 and a vertical frame plate 23 fixed on the rotating shaft 20. Horizontal limit wheels 19 are rotatably installed at both ends of the horizontal frame plate 21, and vertical limit wheels 22 are rotatably installed at both the upper and lower ends of the vertical frame plate 23. The two horizontal limit wheels 19 are located on both sides of the horizontal frame plate 21, and the two vertical limit wheels 22 are located on both sides of the vertical frame plate 23. Two mounting plates 17 and two mounting plates 16 are fixed inside the outer casing 9. The two mounting plates 17 are respectively provided with limiting slides 1 for guiding the left and right horizontal limit wheels 19, and the two mounting plates 16 are respectively provided with limiting slides 2 for guiding the up and down vertical limit wheels 22.

[0033] The circulating drive motor drives the circulating sprocket 18 to rotate, which in turn drives the circulating chain to rotate clockwise. This causes the circulating slider 11 to slide clockwise around the circulating slide groove 10. When the horizontal bracket 12 moves to the side of the conveyor 1, the conveyor 1 transports the pallet to the horizontal bracket 12. Then, the horizontal bracket 12 carries the pallet and rises. When the circulating slider 11 slides to the upper part and needs to turn, the rotating shaft remains stationary under the action of the vertical limit wheel 22, the horizontal limit wheel 19, the first limit slide, and the second limit slide, thus keeping the horizontal bracket 12 in a horizontal state.

[0034] The shelf includes a mobile frame 2, with a placement rack 5 fixed on the top of the mobile frame 2. The placement rack 5 has an inlet on the side facing the vertical circulation lifting mechanism, and multiple pairs of trays 3 are provided on the inner side wall of the placement rack 5 along the vertical direction.

[0035] Limiting rods 4 are provided on both sides of the placement rack 5. An L-shaped hanging rod 15 is fixed on the limiting rod 4. A hanging plate 13 is fixed on the placement rack 5. The hanging plate 13 has a hanging hole for the outer end of the hanging rod 15 to be inserted. Before the tray is placed, the limiting rod 4 on the side closer to the horizontal bracket 12 is lifted upward, so that the hanging rod 15 is disengaged from the hanging hole on the hanging plate 13, preventing the limiting rod 4 from affecting the tray placement. After the tray is placed, the frame 2 is moved away from the tray placement position, and then the limiting rod 4 on the side closer to the horizontal bracket 12 is put back on.

[0036] The tray arrangement mechanism includes a lifting mechanism, on which a lifting frame 6 is mounted. A horizontal support 12 has multiple clearance slots. Multiple lever plates 14, passing through the clearance slots, are fixed to the lifting frame 6. Each lever plate 14 has a rotating tray conveyor belt 24 rotatably mounted on it, with the outer end of the conveyor belt 24 extending into the rack. The lever plates 14 are staggered left and right along the front-to-back direction. The inner ends of the multiple conveyor belts 24 share a common drive shaft, which is connected to a drive motor 25.

[0037] The lifting mechanism includes a lifting frame plate 8, on which a linear guide rail module 7 is mounted, and a lever arm plate 14 is installed on the linear guide rail module 7. As the horizontal bracket 12 descends, the pallets on it fall onto the swing conveyor belt of the lever arm plate 14, and are then transported by the swing conveyor belt into the placement frame 5, where they are supported on the pallet plate 3. Each time a pallet is placed, the linear guide rail module 7 lowers the lifting frame plate 8 by the height of one pallet, facilitating the placement of the received pallet onto the next pallet plate 3. After the pallet is placed on the pallet plate 3, its outer edge maintains a certain distance from the side wall of the pallet plate 3.

This narrative style is merely for clarity.
