Description

Technical Field

[0001] The utility model belongs to the technical direction of pallet stacking, and specifically relates to an automatic pallet stacking and falling mechanism. Background Technique

[0002] A pallet is a base made to facilitate the placement of scattered items and shipping requirements. It is generally square or rectangular, and it has the same meaning as a pallet, referring to the same thing. Due to differences in cargo types, some pallets also include a top cover. When users use pallets, they need to stack them, and a falling mechanism is required when users need to stack pallets.

[0003] The following problems exist in the prior art:

[0004] 1. The existing pallets on the market are heavy. After a day of handling by operators, the labor intensity is high, and it is very easy to have work-related injuries. They cannot be adapted to automated production lines, and the efficiency and electrification level cannot meet the current market demand. Moreover, manual placement of pallets on the line will pose a safety hazard;

[0005] 2. The existing automatic pallet stacking and falling mechanisms on the market are prone to breakage when users need to use them, thus increasing the maintenance cost for users. Content of the Utility Model

[0006] The purpose of the utility model is to provide an automatic pallet stacking and falling mechanism for the existing device to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model provides the following technical solution: an automatic pallet stacking and falling mechanism, including a frame, the upper surface of the frame is limitedly connected with a rotary support cylinder, the upper surface of the frame is limitedly connected with a lifting reduction motor, and the upper surface of the frame is fixedly connected with a pallet storage station.

[0008] The upper surface of the frame is limitedly clamped with a pallet, and the inner side surface of the frame is limitedly connected with a pallet chain line.

[0009] The bottom surface of the pallet chain line is limitedly connected with a support frame assembly, the bottom surface of the support frame assembly is fixedly connected with a threaded rod, the outer surface of the threaded rod is limitedly connected with a second nut, and the upper surface of the frame is limitedly connected with a lifting separation mechanism.

[0010] The utility model further explains that the bottom surface of the frame is fixedly connected with a limiting plate, and the number of limiting plates is multiple and parallel to each other.

[0011] With the above technical solution, the limiting plates, which are multiple in number and parallel to each other, can facilitate the user to limit and connect the frame.

[0012] The present utility model further illustrates that limiting openings are formed through the surface of the limiting plate, and the number of limiting openings is multiple.

[0013] With the above technical solution, the multiple limiting openings in this solution can facilitate the user to limit and install the limiting plate with bolts.

[0014] The present utility model further illustrates that a non-slip bottom plate is limit-connected to the bottom surface of the threaded rod, and the non-slip bottom plate is connected between the threaded rod and the support frame assembly.

[0015] With the above technical solution, the non-slip bottom plate connected between the threaded rod and the support frame assembly in this solution can facilitate the user to anti-slip support the support frame assembly.

[0016] The present utility model further illustrates that a lifting transmission mechanism is limit-connected to the upper surface of the frame, and the number of lifting transmission mechanisms is multiple.

[0017] With the above technical solution, the multiple lifting transmission mechanisms in this solution can facilitate the user to output transmission power.

[0018] The present utility model further illustrates that a first nut is limit-connected to the outer surface of the threaded rod, and the first nut is connected between the threaded rod and the support frame assembly.

[0019] With the above technical solution, the first nut connected between the threaded rod and the support frame assembly in this solution can facilitate the user to connect the first nut and the support frame assembly.

[0020] Compared with the prior art, the beneficial effects achieved by the present utility model are:

[0021] The utility model provides an automatic stacking and dropping mechanism for pallets. Through the mutual cooperation and use of a frame, a lifting transmission mechanism, a rotary support cylinder, a lifting separation mechanism, a lifting reduction motor, pallets, a pallet storage station, a pallet chain line, a limiting plate, a limiting opening, a first nut, a second nut, a threaded rod, an anti-slip bottom plate, and a support frame assembly, it is convenient for users to use the dropping mechanism. The operator uses a forklift to put multiple layers of pallets into the pallet storage station at one time. According to the signal sent by the pallet chain line indicating the need to replenish pallets, the lifting reduction motor drives the chain to drive the lifting transmission mechanism to rotate. The lifting separation mechanism drives the pallet to move downward to the pallet chain line, and the pallet smoothly lands on the chain line. The rotary support cylinder pushes the support rod to separate from the pallet. The lifting reduction motor drives the lifting separation mechanism to rise to the position of the second-layer pallet. The rotary support cylinder pushes the support rod to combine with the pallet. The lifting reduction motor then drives the lifting separation mechanism to lift all pallets except the first-layer pallet and separate them from the first-layer pallet. The first-layer pallet smoothly moves on the pallet chain line, meeting the user's need for automatic stacking and dropping.

[0022] The utility model provides an automatic stacking and dropping mechanism for pallets. The lifting function is realized by using a cylinder to lift the pallet. Now it is upgraded to be driven by a reduction motor. The motor is more stable and durable than the cylinder, has a larger torque, and can achieve parking at multiple positions. Moreover, its pallet support mechanism is upgraded. Traditionally, the cylinder directly supports all pallets, which easily causes the cylinder to wear and leak air. Now it is upgraded to use a cylinder to drive a lever to support all pallets. The lever is stressed by a copper sleeve, has a large bearing capacity, and the cylinder is not directly stressed, meeting the user's usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In this embodiment, a limiting plate 9 is fixedly connected to the bottom surface of the frame 1, and the number of the limiting plates 9 is multiple and they are parallel to each other. The multiple limiting plates 9 that are parallel to each other can facilitate the user to perform limit connection on the frame 1. A limiting opening 10 is penetrated through the surface of the limiting plate 9, and the number of the limiting openings 10 is multiple. The multiple limiting openings 10 can facilitate the user to perform limit installation on the limiting plate 9 with bolts. Embodiment

[0037] In this embodiment, a non-slip bottom plate 14 is connected to the bottom surface of the threaded rod 13 in a limited manner, and the non-slip bottom plate 14 is connected between the threaded rod 13 and the support frame assembly 15. The non-slip bottom plate 14 connected between the threaded rod 13 and the support frame assembly 15 can facilitate the user to use anti-slip support for the support frame assembly 15. An elevating transmission mechanism 2 is connected to the upper surface of the frame 1 in a limited manner, and the number of the elevating transmission mechanisms 2 is multiple. The multiple elevating transmission mechanisms 2 can facilitate the user to output transmission power for use. Embodiment

[0038] As Figures 1-8 shown, on the basis of Embodiment 1 and Embodiment 2, the present utility model provides a technical solution: Preferably, a threaded rod 13 is fixedly connected to the bottom surface of the support frame assembly 15, and a second nut 12 is connected to the outer surface of the threaded rod 13 in a limited manner. An elevating separation mechanism 4 is connected to the upper surface of the frame 1 in a limited manner.

[0039] In this embodiment, a first nut 11 is connected to the outer surface of the threaded rod 13 in a limited manner, and the first nut 11 is connected between the threaded rod 13 and the support frame assembly 15. The first nut 11 connected between the threaded rod 13 and the support frame assembly 15 can facilitate the user to connect the first nut 11 and the support frame assembly 15.

[0040] As Figures 1-8 shown, when the user needs to use it, the operator uses a forklift to put multiple pallets 6 into the pallet storage station 7 at one time. According to the signal sent by the pallet chain line 8 that the pallet 6 needs to be replenished, the elevating reduction motor 5 drives the chain to drive the elevating transmission mechanism 2 to rotate. The elevating separation mechanism 4 drives the pallet 6 to move downward to the pallet chain line 8. The pallet 6 lands smoothly on the chain line. The rotating support cylinder 3 pushes the support rod to separate from the pallet 6. The elevating reduction motor 5 drives the elevating separation mechanism 4 to rise to the position of the second-layer pallet. The rotating support cylinder pushes the support rod to combine with the pallet 6.

The pallet 6 on the first layer moves smoothly on the pallet chain line. In this way, the user can perform the use of automatic stacking and falling, and realize the elevating function by setting the method of using a cylinder to jack up the pallet. The existing one is upgraded to be driven by a reduction motor. The motor is more stable and durable than the cylinder, has a larger torque, and can achieve parking at multiple positions. And its pallet support mechanism is upgraded. Traditionally, the cylinder directly supports all the pallets, which easily causes the cylinder to wear and leak air. The existing one is upgraded to use a cylinder to drive a lever to support all the pallets. The lever is stressed by a copper sleeve, has a large bearing capacity, and the cylinder is not directly stressed. In this way, the user can perform the use.
