DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Please refer to Figures 1 to 5 , and a palletizing device provided by the present invention will be described. The palletizing device includes a frame 1, a sliding frame 2, a pulley assembly 4, a limiting member 8, a gear assembly 6, and a support rod 7. The frame 1 is a rectangular frame structure, and the frame 1 is provided with traveling wheels 11; the sliding frame 2 is a rectangular frame structure; it is slidably connected to the frame 1 and is used to move up and down along the height direction of the frame 1; a material receiving assembly 3 is rotatably connected to the sliding frame 2; a rack 21 is provided on the sliding frame 2; the pulley assembly 4 is fixedly connected to the frame 1, one end of the pulley assembly 4 is connected to the sliding frame 2, and the other end is connected to a counterweight 5 for controlling the moving trend of the sliding frame 2; the limiting member 8 is arranged at the lower part of the frame 1 and is used to block the sliding frame 2 from continuing to move downward; the support rod 7 is connected to the pulley assembly 4 and is used to be engaged with or separated from the material receiving assembly 3 as the counterweight 5 moves; the gear assembly 6 is arranged on the frame 1 and is used to engage with the rack 21 and drive the traveling wheels 11 to rotate as the sliding frame 2 moves.

[0037] When the palletizing device performs palletizing operations, an externally connected feeding channel will transport the palletizing parts to the material receiving assembly 3 for row stacking. After the row stacking operation is completed, at this time, the sum of the weights of the support rod 7, the sliding frame 2, the material receiving assembly 3, and the palletizing parts is greater than the weight of the counterweight 5. The sliding frame 2, the support rod 7, the material receiving assembly 3, and the palletizing parts will move downward as a whole, and drive the counterweight 5 to move upward. When the sliding frame 2, the support rod 7, and the palletizing parts move to the position of the limiting member 8, the sliding frame 2 is blocked by the limiting member 8 and stops moving. At this time, the sum of the weights of the support rod 7, the material receiving assembly 3, and the palletizing parts is still greater than the weight of the counterweight 5, and the support rod 7 and the palletizing parts have a tendency to continue moving downward; the support rod 7 is separated from the material receiving assembly 3, and the palletizing parts force the material receiving assembly 3 to rotate to unload the palletizing parts. After the palletizing operation is completed, the sum of the weights of the support rod 7, the material receiving assembly 3, and the sliding frame 2 is less than the weight of the counterweight 5. The counterweight 5 drives the support rod 7, the material receiving assembly 3, and the sliding frame 2 to move upward. After returning to the original position, it waits for the start of the next palletizing operation. During the up and down movement of the sliding frame 2, it will drive the rotation of the gear structure in the gear assembly 6, and the rotation of the gear structure will drive the traveling wheels 11 and then drive the movement of the entire palletizing device.

[0038] A palletizing device provided by the present invention, compared with the prior art, converts the potential energy generated during the palletizing operation into kinetic energy that provides power for the sliding frame 2, eliminating the lifting motor that drives the sliding frame 2, enabling the sliding frame 2 to automatically complete the descending and ascending actions under the cooperation of the counterweight 5, the support rod 7, the material receiving assembly 3, and the pulley assembly 4, saving electricity and effectively reducing the cost of the palletizing operation. The gear assembly 6 is connected to the sliding frame 2, and the gear assembly 6 can drive the rotation of the traveling wheels 11 as the sliding frame 2 moves up and down, effectively saving electric power resources and reducing the cost of the palletizing operation.

[0039] It should be noted that the limiting member 8 only blocks the downward movement of the sliding frame 2 and has no influence on the motion state of the support rod 7.

[0040] In this embodiment, the limiting member 8 can be one or several structural members such as a stop block, a clamping plate, an electromagnetic chuck, etc., as long as it can block the movement of the sliding frame 2.

[0041] In this embodiment, the support rod 7 is slidably connected to the side frame of the frame 1. The support rod 7 includes a first support portion for clamping with the sliding frame 2 and a second support portion for clamping with the material receiving assembly 3.

[0042] As a specific implementation manner of the embodiment of the present invention, please refer to Figures 1 to 5 , the pulley assembly 4 includes a first pulley 41, a second pulley 42, a third pulley 43, and a connecting rope 44. The first pulley 41 is fixedly connected to the frame 1; the second pulley 42 is fixedly connected to the frame 1; the third pulley 43 is fixedly connected to the support rod 7; one end of the connecting rope 44 is fixedly connected to the counterweight 5, and the other end sequentially bypasses the first pulley 41, the third pulley 43, the second pulley 42, and is fixedly connected to the sliding frame 2. The first pulley 41 and the second pulley 42 are spaced apart, and the third pulley 43 is located between the first pulley 41 and the second pulley 42. The pulley assembly 4 completes the operation of converting kinetic energy into potential energy and then converting potential energy back into kinetic energy, enabling the palletizing device to complete the up and down movement of the sliding frame 2 relative to the frame 1 without using a lifting motor, reducing the production cost and use cost of the palletizing device. The pulley assembly 4 is composed of multiple pulleys, and the friction between the pulley structure and the connecting rope 44 is small, which can effectively reduce the energy loss during the conversion of potential energy and kinetic energy.

[0043] In this embodiment, the first pulley 41 and the second pulley 42 are fixed pulleys, and the third pulley 43 is a movable pulley.

[0044] In this embodiment, the connecting rope 44 is one or several ropes such as a steel wire rope, a nylon rope, a synthetic fiber rope, etc., as long as it meets the requirements of wear resistance and long service life.

[0045] As a specific implementation manner of the embodiment of the present invention, the pulley assembly 4 may also only include the first pulley 41 and the connecting rope 44. At this time, one end of the connecting rope 44 is fixedly connected to the counterweight 5, and the other end of the connecting rope 44 bypasses the first pulley 41 and is fixedly connected to the support rod 7. At this time, the sliding frame 2 is slidably connected to the frame 1; the support rod 7 is clamped to the lower end surface of the sliding frame 2 and the lower end surface of the material receiving assembly 3. During the blanking process, the sliding frame 2 moves as the support rod 7 moves downward until it reaches the position of the limiting member 8. The sliding frame 2 stops moving, and the support rod 7 continues to move downward. The palletizing member placed on the material receiving assembly 3 presses the material receiving assembly 3, and the material receiving assembly 3 rotates to complete the palletizing and unloading action. At this time, the support rod 7 is located below the material receiving assembly 3. After the unloading operation is completed, the support rod 7 moves upward under the action of the counterweight 5, the material receiving assembly 3 returns to its original position under the action of the support rod 7, and then the support rod 7 drives the sliding frame 2 and the material receiving assembly 3 to rise back to the initial position.

[0046] It should be noted that the first pulley 41 is a fixed pulley fixedly connected to the frame 1.

[0047] In this embodiment, the connecting rope 44 is one or several of ropes such as steel wire ropes, nylon ropes, and synthetic fiber ropes, as long as it satisfies friction resistance and a long service life.

A plurality of connecting rods are spaced on the side frame of the fixed frame, and each connecting rod is respectively hinged to the side frame of the sliding frame 2; the plurality of rollers are arranged on the fixed frame at intervals along the length direction of the fixed frame.

[0049] In this embodiment, the fixed frame is also provided with rolling wheels, which avoid the phenomenon of jamming between the fixed frame and the support rod 7 during the movement process.

[0050] As a specific implementation manner of a palletizing device provided by the present invention, please refer to Figure 1 , pulley assemblies 4 are respectively provided at both ends of the frame 1; the first pulley 41 at one end of the frame 1 and the first pulley 41 at the other end of the frame 1 are fixedly connected by means of a connecting shaft 45.

The rack 21 is arranged on the sliding frame 2, and the sliding frame 2 reciprocates up and down along the height direction of the frame 1, correspondingly driving the rack 21 to reciprocate up and down along the height direction of the frame 1. During the process of the rack 21 moving downward, it will drive the rotation of the driving wheel 61. The rotation of the driving wheel 61 drives the rotation of the driven wheel 62, and the rotation of the driven wheel 62 drives the rotation of the traveling wheel 11, so that the palletizing device moves from one position to another; correspondingly, when the rack 21 moves upward, the traveling wheel 11 will drive the palletizing device back to its original position. The sliding frame 2 continuously reciprocates up and down, and correspondingly the traveling wheel 11 drives the palletizing device to continuously complete the "movement - return" action, so that the palletizing device can complete the palletizing operation of different layers at the same palletizing position without using a motor structure.
