Description

Technical Field

[0001] This utility model relates to the field of sheet metal production and processing equipment, and in particular to a pallet clamping mechanism for an automatic pallet loading and flipping machine with a pallet. Background Technology

[0002] In stone processing plants, slab turning machines are commonly used equipment for handling stone slabs and are an indispensable necessity in large stone slab production lines. Generally, slab turning machines handle bare slabs, but sometimes pallets must be used, especially when handling fragile or severely cracked slabs. Pallets are needed to support the slabs during loading, unloading, and inter-process transport to prevent breakage. Once a slab is loaded onto a pallet, it remains attached to the pallet throughout the entire processing until the pallet separates from the slab at the end of the process. This allows irregularly shaped stone slabs to be standardized using pallets, enabling automated operation on the production line.

[0003] In the existing technology, the automatic pallet loading and flipping machine with tray has two disadvantages:

[0004] 1. The connection between the pallet and the rollers on the loading machine table is very loose, and the two cannot be clamped tightly. During the loading process, it is inevitable that the pallet will shake, vibrate, and be impacted, and there is even a risk of it slipping out or falling off, which does not meet the requirements of safety and reliability.

[0005] This risk stems from the technological requirements and mechanical structure of the machine, making it difficult to avoid. Because pallets continuously move in and out of the flipping machine, a sufficiently large gap must be maintained between the clamping rollers fixed to both sides of the table and the grooves on both sides of the pallet, both vertically and horizontally. This large gap means that as the pallet rises from horizontal to vertical (or even greater than 90°) during loading, it will inevitably drift within the gap due to gravity, posing a significant safety hazard.

[0006] 2. Relying solely on the tension generated by a vacuum suction cup on the back of the slab to fix it in place and flip it over is not safe or reliable enough. Suction cups are ineffective for travertine, sandstone, or stone slabs with holes or cracks. Using suction cups alone may result in the slab falling or being dropped due to the suction cups failing to hold it in place.

[0007] In conclusion, the development of an efficient, safe, and reliable automatic pallet-loading machine is an urgent need for the stone industry. Utility Model Content

[0008] Therefore, in view of the above problems, this utility model proposes a pallet clamping mechanism for an automatic pallet loading and flipping machine with a pallet, which solves the problem that existing flipping machines are difficult to adapt to the loading of fragile or severely cracked boards during use.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a pallet clamping mechanism for an automatic pallet loading and flipping machine with pallets, comprising a transport base, an upper frame disposed on the transport base, a pallet disposed on the upper frame, pallet clamping mechanisms for clamping the pallet disposed on both sides of the upper frame in its width direction, and a plurality of parallel rollers for carrying and conveying the pallet disposed on the upper frame.

[0010] Furthermore, the pallet clamping mechanism includes a first pallet clamping mechanism and a second pallet clamping mechanism that cooperate with each other, and the first pallet clamping mechanism and the second pallet clamping mechanism work together to clamp the pallet.

[0011] Furthermore, the first pallet clamping mechanism includes a lifting cylinder mounting plate, a first guide wheel lifting cylinder fixedly mounted on the lifting cylinder mounting plate, and a first pallet guide wheel mounted on the first guide wheel lifting cylinder. The first pallet guide wheel is lifted up and down by driving the first guide wheel lifting cylinder.

[0012] Furthermore, the second pallet clamping mechanism includes a lifting cylinder mounting base, a lifting cylinder mounting base pushing cylinder for pushing the lifting cylinder mounting base, a second stop wheel lifting cylinder disposed on the lifting cylinder mounting base, and a second pallet stop wheel disposed on the second stop wheel lifting cylinder, wherein the second pallet stop wheel is lifted up and down by driving the second stop wheel lifting cylinder.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] 1. The technical solution proposed in this utility model can effectively prevent the boards from breaking during the boarding process when they are fragile or severely cracked. It provides protection for the boards during the work process and improves the safety of the boarding work.

[0015] 2. In this utility model, both the first and second pallet guide wheels on both sides of the pallet are movable structures. The first pallet guide wheel can move vertically, and the second pallet guide wheel can move both vertically and horizontally, ensuring that the horizontal distance between them can be flexibly adjusted. By widening the distance between them, the pallet can be easily moved in and out, and by narrowing the distance between them, the pallet can be clamped. At the same time, the first and second pallet guide wheels can clamp the pallet by moving up and down vertically. When raised, the pallet can be easily moved in, and when lowered, the gap between the lower edges of the pallet slot can be eliminated, so that the pallet and the roller are tightly pressed together and do not detach.

[0016] 3. At the same time, based on this utility model, it is easy to add a device for gripping the plate above the tray. This enables reliable loading when suction cups cannot be used. When suction cups can be used for suction-type loading, the gripping mechanism can also perform auxiliary loading operations simultaneously, greatly improving safety. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a pallet clamping mechanism for an automatic pallet loading and flipping machine with a pallet, including a transport base 1, an upper frame 2 disposed on the transport base 1, a pallet 3 disposed on the upper frame 2, pallet clamping mechanisms for clamping the pallet 3 disposed on both sides of the upper frame 2 in its width direction, and a plurality of parallel rollers 6 disposed on the upper frame 2 for carrying and conveying the pallet 3.

[0024] The pallet clamping mechanism includes a first pallet clamping mechanism 4 and a second pallet clamping mechanism 5 that cooperate with each other. The first pallet clamping mechanism 4 and the second pallet clamping mechanism 5 work together to clamp the pallet 3. The first pallet clamping mechanism 4 includes a lifting cylinder mounting plate 41, a first stop wheel lifting cylinder 42 fixedly mounted on the lifting cylinder mounting plate 41, and a first pallet stop wheel 43 mounted on the first stop wheel lifting cylinder 42. The first pallet stop wheel 43 is lifted up and down by driving the first stop wheel lifting cylinder 42. The second pallet clamping mechanism 5 includes a lifting cylinder mounting seat 51, a lifting cylinder mounting seat pushing cylinder for pushing the lifting cylinder mounting seat 51, a second stop wheel lifting cylinder 52 mounted on the lifting cylinder mounting seat 51, and a second pallet stop wheel 53 mounted on the second stop wheel lifting cylinder 52. The second pallet stop wheel 53 is lifted up and down by driving the second stop wheel lifting cylinder 52. The lifting cylinder mounting seat pushing cylinder is a conventional driving device, which will not be described in detail here.

[0025] The working principle of this utility model is as follows:

[0026] 1. The first tray stop roller 43 and the second tray stop roller 53 on both sides of the tray 3 are flexible. The horizontal distance between the second tray stop roller 53 and the first tray stop roller 43 can be adjusted by adjusting the second tray stop roller 53. The distance can be increased or decreased as needed. Increasing the distance facilitates the entry and exit of the tray 3, and decreasing the distance eliminates the horizontal gap when the tray is placed on the upper plate to clamp the tray 3. The first tray stop roller 43 and the second tray stop roller 53 can be raised and lowered vertically to clamp the tray 3 vertically.
