Description

Technical Field

[0001] This utility model relates to the field of material palletizing technology, specifically an anti-tipping structure for palletizing machines. Background Technology

[0002] Automatic palletizers can automatically grab goods that need to be stacked and arrange them on freight pallets in a certain order. However, during the stacking process, if the goods are cylindrical items such as rolled-up fabric, they are prone to rolling off the edge of the stack after reaching a certain height. This is because there are no items pressing down on them and their shape makes them more likely to fall off. Furthermore, fabric is often wrapped in plastic bags during stacking, and the low friction between the bags makes it even easier for the goods to fall off. After stacking, if the pallet is moved by forklift, the top item may shake and fall off, resulting in uneven weight distribution on the pallet and potentially causing the entire pallet to tip over, which is quite inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide an anti-tipping structure for palletizing machines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An anti-tipping structure for palletizing machines includes:

[0006] The system includes a pallet capable of supporting stacked goods, a limiting frame capable of restricting the stacked goods, a lifting mechanism capable of controlling the height of the limiting frame, and four limiting mechanisms. The limiting frame is located above the pallet. The lifting mechanism is fixedly connected to the pallet. The lifting mechanism includes two inserts, which are fixedly connected to opposite sides of the pallet. Inserts are movably inserted into the two inserts, and lifting boxes are fixedly connected to the tops of the two inserts. Electric hoists are installed inside the two lifting boxes, and each electric hoist is equipped with a winch. One end of each winch is fixedly connected to the top surface of the limiting frame. The four limiting mechanisms are fixedly connected to the four sides of the top surface of the limiting frame.

[0007] Furthermore, the limiting frame is fixedly connected to sliding cylinders on both sides, and the two insert rods are slidably sleeved inside the two sliding cylinders respectively.

[0008] Furthermore, the limiting mechanism includes:

[0009] The system consists of a U-shaped frame, a rotating rod, and multiple take-up reels. The bottom surface of the U-shaped frame is fixedly connected to the top surface of the limiting frame. The rotating rod is rotatably connected between the two arms of the U-shaped frame. Multiple take-up reels are fixedly sleeved on the outer side wall of the rotating rod. Each take-up reel has a limiting rope fixedly wound inside. One end of each limiting rope is fixedly connected to a hook. Multiple hooks are fixedly connected to the four side walls of the tray. Each hook is movably hooked to an adjacent hook.

[0010] Furthermore, each U-shaped frame is fixedly connected to a drive box at one end, each drive box contains a drive motor, and the motor shaft of each drive motor is fixedly connected to one end of the adjacent rotating rod.

[0011] Furthermore, all of the limiting ropes are made of nylon.

[0012] Furthermore, multiple connecting plates are fixedly connected to the outer wall of each lifting box.

[0013] Furthermore, each connecting plate is rotatably connected to a baffle at one end, each baffle is provided with a torsion spring at one end, and each torsion spring is fixedly connected at one end to one end of the adjacent baffle and at the other end to one end of the adjacent connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The automatic stacker crane stacks goods onto pallets. An electric hoist pulls a limiting frame along a guide rod using a winch, securing the stacking layers and preventing goods at the edges from falling. When the limiting frame rises, a drive motor activates a rotating rod and a reel to release a taut connecting rope, further limiting the goods below the frame. After use, the rope can be pulled off the adjacent connecting plate and placed on the goods. The rope can then be secured to hooks to further prevent pallets from tipping over due to falling goods.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the utility model, an anti-tipping structure for palletizing a palletizer includes:

[0023] The system includes a pallet 100 capable of supporting stacked goods, a limiting frame 200 capable of limiting the stacked goods, a lifting mechanism 300 capable of controlling the height of the limiting frame 200, and four limiting mechanisms 400. The limiting frame 200 is located above the pallet 100. The lifting mechanism 300 is fixedly connected to the pallet 100. The lifting mechanism 300 includes two inserts 310, which are fixedly connected to opposite sides of the pallet 100. Insert rods 320 are movably inserted into the two inserts 310, and lifting boxes 330 are fixedly connected to the top of the two insert rods 320. Electric hoists are installed inside the two lifting boxes 330, and each electric hoist is equipped with a winch 331. One end of each winch 331 is fixedly connected to the top surface of the limiting frame 200. The four limiting mechanisms 400 are fixedly connected to the four sides of the top surface of the limiting frame 200.

[0024] Specifically, pallet 100 is an existing freight pallet 100 used to carry stacked goods. When the automatic stacker crane stacks goods on pallet 100, the limit frame 200 can be moved by starting two electric hoists and using winch 331 to frame the stacking layer that the automatic stacker crane is stacking, preventing goods at the edge of the stacking layer from falling due to slippage of packaging bags, thus facilitating the stacking operation of the automatic stacker crane. After stacking is completed, the insert rod 320 can be pulled out of the insert cylinder 310 and inserted into the insert cylinder 310 on the new pallet 100, using the limit frame 200 to limit the goods on the new pallet 100.

[0025] Example 1

[0026] like Figure 1-2 As shown, in this embodiment, the limiting frame 200 is fixedly connected to the sliding cylinders 210 on both sides, and the two insert rods 320 are respectively slidably sleeved inside the two sliding cylinders 210.

[0027] In this embodiment, by inserting the rod 320 into the slide cylinder 210 before inserting the rod 320 into the slide cylinder 310, the limiting frame 200 can be made to climb along the rod 320, thereby restricting the movement path of the limiting frame 200 and preventing the limiting frame 200 from shaking when it is driven by the winch 331.

[0028] like Figure 1 and Figure 4 As shown, in this embodiment, the limiting mechanism 400 includes:

[0029] The system comprises a U-shaped frame 410, a rotating rod 420, and multiple take-up reels 440. The bottom surface of the U-shaped frame 410 is fixedly connected to the top surface of the limiting frame 200. The rotating rod 420 is rotatably connected between the two arms of the U-shaped frame 410. Multiple take-up reels 440 are fixedly sleeved on the outer side wall of the rotating rod 420. Each take-up reel 440 has a limiting rope 441 fixedly wound inside. Each limiting rope 441 has a hook 442 fixedly connected to one end. Each of the four side walls of the tray 100 has multiple hook rings 110 fixedly connected. Each hook 442 is movably hooked to an adjacent hook ring 110. Each U-shaped frame 410 has a drive box 430 fixedly connected to one end. Each drive box 430 has a drive motor inside. The motor shaft of each drive motor is fixedly connected to one end of an adjacent rotating rod 420. Each limiting rope 441 is made of nylon.

[0030] In practice, after inserting the rod 320 into the adjacent cylinder 310, multiple hooks 442 can be hooked onto the adjacent hook ring 110. When the automatic stacker is stacking, the limit frame 200 relies on the pull of the electric hoist and the winch 331 to always frame the stacking layer. When the position of the limit frame 200 changes, the drive motor can be started to drive the adjacent rotating rod 420 to rotate, so that the rotating rod 420 drives the adjacent winding reel 440 to release the adjacent limit rope 441, so that all the limit ropes 441 are taut to block the stacked goods below the limit frame 200, preventing the goods below the limit frame 200 from falling. The drive motor is equipped with an electromagnetic brake, so the motor shaft will not rotate when the drive motor is not started. The limit rope 441 is made of nylon, which has low elasticity and is not easy to stretch, thus limiting the goods.

[0031] Example 2

[0032] Based on Embodiment 1, the connecting plate 340 and the baffle 341 are provided to facilitate the fixing of the stacked goods.

[0033] like Figure 1-3As shown, in this embodiment, multiple connecting plates 340 are fixedly connected to the outer wall of any lifting box 330, a baffle 341 is rotatably connected to one end of any connecting plate 340, a torsion spring is provided at one end of any baffle 341, one end of any torsion spring is fixedly connected to one end of the adjacent baffle 341, and the other end is fixedly connected to one end of the adjacent connecting plate 340.

[0034] In practice, before the insertion rod 320 is inserted into the adjacent insertion cylinder 310, a rope is pre-laid on the connecting plate 340. Then, when the limiting mechanism 400 and the lifting mechanism 300 are used, as shown... Figure 1 As shown, the middle of the rope is supported by the connecting plate 340, making the overall position of the rope higher, with both ends hanging down to the ground. The rope passes through the inside of the limiting frame 200 and is close to the limiting frame 200, providing sufficient space for the automatic stacker crane to stack. This makes it less likely for the automatic stacker crane to be interfered with by the rope during stacking. After the goods on the pallet 100 are stacked, the rope can be manually pulled on the ground, causing the part supported by the connecting plate 340 to push open the baffle 341 and fall onto the top goods. Then, the two ends of the rope are tied to the adjacent hooks 110, thereby placing the goods... The goods are secured to the pallet 100 with ropes to reduce the risk of slipping and falling, which could cause the pallet 100 to tip over. Then, the limiting frame 200 is raised to its maximum height, the insert rod 320 is pulled out of the insert cylinder 310, and the hook 442 is removed from the hook ring 110. The limit frame 200 and the hook are then removed from the pallet 100 together. In the initial state, the baffle 341 is always perpendicular to the adjacent connecting plate 340 under the action of the torsion spring. When the rope is pulled manually, it can push the baffle 341 away from the adjacent connecting plate 340.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
