Description

Technical Field

[0001] The present invention relates to the technical field of stacking equipment, and particularly relates to a distribution pallet mechanism for stacking. Background Art

[0002] Pallets can be divided into wooden pallets, plastic pallets, iron pallets, etc. Usually, pallets play an important role in logistics and warehousing, mainly used for the loading, unloading, storage and transportation of goods. Since pallets are stacked, a distribution pallet mechanism is required to distribute the stacked pallets.

[0003] However, traditional distribution pallet mechanisms usually place several pallets in a stacked state on the transmission mechanism as a whole, so that the first-layer pallet contacts the transmission mechanism, and then the insertion plate of the distribution pallet mechanism is inserted into the socket of the second-layer pallet to lift the second-layer and above pallets together, so that the first-layer pallet is transmitted by the transmission mechanism. When the second-layer and above pallets need to be transmitted, the same operation is performed as the first-layer pallet. Since several pallets are stacked on the transmission mechanism uniformly, the weights of pallets made of different materials are different. The iron pallet has a large weight, and such an operation will cause damage to the transmission mechanism and affect the service life of the transmission mechanism. Therefore, the present invention proposes a distribution pallet mechanism for stacking. Summary of the Invention

[0011] As a preferred technical solution of the present invention, the fixed block one is penetrated by the two-way screw rod two, and the fixed plate one, the fixed plate two, and the fixed plate three have the same length.

[0012] As a preferred technical solution of the present invention, a diversion structure is arranged on the top of the base. The diversion structure includes an electric telescopic rod one.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting the distribution pallet structure, it is beneficial to avoid several pallets forming a stack until they are placed on the first transmission mechanism during the distribution pallet process, so as to prevent damage to the first transmission mechanism caused by its own gravity and reduce the service life. At the same time, the setting of the spring plays a buffering role for the first support plate and improves its service life;

[0019] 2. By setting the limiting component in cooperation with the distribution pallet structure, it is beneficial to enable the distribution pallet mechanism to perform limit adjustment according to the size of the pallet. At the same time, the setting of the first rotating roller and the second rotating roller reduces the resistance for the pallet to move up or down;

[0020] 3. By setting the auxiliary component in cooperation with the distribution pallet structure, it is beneficial to enhance the stability of the second fixing plate and the third fixing plate during movement. At the same time, the supporting force of the parts of the second fixing plate and the third fixing plate far from the base is strengthened, so that the linkage and stability of the limiting component are enhanced;

[0021] 4. By setting the supporting component in cooperation with the distribution pallet structure, it is beneficial to greatly improve the supporting force and stability of the clamping plate and the first fixing plate, and relieve the pressure on the clamping plate from the pallet;

[0022] 5. By setting the diversion structure in cooperation with the distribution pallet structure, it is beneficial to dock the pallets conveyed on the first transmission mechanism. At the same time, the height position of the fourth transmission mechanism itself can be adjusted. At the same time, the control component cooperates with the diversion structure to adjust and limit the angular position of the fourth transmission mechanism, so that the fourth transmission mechanism can convey the pallets to the second transmission mechanism or the third transmission mechanism for diversion work according to needs;

[0023] 6. By setting up a supporting auxiliary structure in conjunction with the diversion structure, it is helpful to support the pallet on the transmission mechanism four, which is convenient for the angle adjustment work after the transmission mechanism four is adjusted in height. At the same time, the setting of the baffle can restrict the pallet to prevent it from leaving the range of the transmission mechanism four after being transmitted to the transmission mechanism four. The U-shaped setting of the pallet two facilitates the angle adjustment work of the transmission mechanism four. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 - 14 As shown, a distribution pallet mechanism for stacking comprises a base 1, a transmission mechanism 1 2, a transmission mechanism 2 3, a transmission mechanism 3 4 and a vertical plate 5 are arranged on the top of the base 1, a storage rack 6 is fixedly arranged on one side of the vertical plate 5, a bidirectional screw rod 1 7 is rotatably arranged on the inner side of the storage rack 6, and one end of the bidirectional screw rod 1 7 passes through the storage rack 6 and is fixedly connected to the output shaft of a motor 1 8, two sliders 1 9 are symmetrically slidably arranged on the outside of the bidirectional screw rod 1 7, a clamping plate 10 is fixedly connected to one side of the slider 9, and a distribution pallet structure 11 is arranged on the top of the base 1;

[0041] The distribution pallet structure 11 includes two cylinders 14 and two first fixing blocks 15. The cylinders 14 are arranged on the top of the base 1. One end of each cylinder 14 is fixedly connected to a storage box 16. A first pallet 17 is slidably arranged inside the storage box 16. A plurality of springs 18 are arranged between the bottom of the first pallet 17 and the inner bottom of the storage box 16. The first fixing blocks 15 are fixedly connected to the clamping plates 10. The top of the first fixing blocks 15 is fixedly connected to a first fixing plate 19. A plurality of first fixing frames 20 are fixedly connected to one side of the first fixing plate 19. A first rotating roller 21 is rotatably arranged inside the first fixing frames 20.

[0042] The distribution pallet structure 11 can prevent a plurality of pallets from forming a stack during the distribution of pallets until they are placed on the first transmission mechanism 2, so as to avoid damaging the first transmission mechanism 2 due to their own gravity and reducing its service life. At the same time, the arrangement of the springs 18 plays a buffering role for the first pallet 17 and improves its service life.

[0043] In this embodiment, the distribution pallet structure 11 further includes two groups of limiting components. The limiting components include two bumps 22. The bumps 22 are fixedly connected to the clamping plates 10 at corresponding positions. A two-way lead screw two 23 is rotatably connected between the two bumps 22. One end of the two-way lead screw two 23 penetrates through one of the bumps 22 and is fixedly connected to the output shaft of the second motor 24. Two sliders two 25 are symmetrically slidably arranged outside the two-way lead screw two 23. The top of each slider two 25 is fixedly provided with a second fixing plate 26. The second fixing plate 26 is fixedly connected to a third fixing plate 28 through a plurality of connecting plates 27. A plurality of second fixing frames 29 are fixedly connected to one side of the third fixing plate 28. A second rotating roller 30 is rotatably arranged inside the second fixing frames 29.

[0044] The limiting components cooperate with the distribution pallet structure 11, enabling the distribution pallet mechanism to perform limit adjustment according to the size of the pallet. At the same time, the arrangement of the first rotating roller 21 and the second rotating roller 30 reduces the resistance when the pallet moves up or down.

[0045] In this embodiment, the distribution pallet structure 11 further includes two groups of auxiliary components. The auxiliary components include a second fixing block 31, a slide bar 32, and two third fixing blocks 33. The second fixing block 31 is fixedly connected to the first fixing plate 19 at the corresponding position. The slide bar 32 is fixedly connected through the second fixing block 31. The third fixing blocks 33 are fixedly connected to the second fixing plate 26, and the third fixing blocks 33 are connected through the slide bar 32.

[0046] The auxiliary components cooperate with the distribution pallet structure 11 to enhance the stability of the second fixing plate 26 and the third fixing plate 28 during movement. At the same time, the supporting force of the parts of the second fixing plate 26 and the third fixing plate 28 away from the base 1 is enhanced, making the linkage and stability of the limiting components stronger.

[0047] In this embodiment, the distribution pallet structure 11 further includes two sets of support components. The support component includes a first support plate 34, the first support plate 34 is fixedly connected to the base 1, a second support plate 35 is fixedly connected to the top of the first support plate 34, a number of first support rods 36 are connected through the first support plate 34, one end of the first support rod 36 is fixedly connected to the corresponding clamping plate 10, two second support rods 37 are connected through the second support plate 35, and one end of the second support rod 37 is fixedly connected to the corresponding first fixing plate 19.

[0048] The support component cooperates with the distribution pallet structure 11 to greatly improve the supporting force and stability of the clamping plate 10 and the first fixing plate 19, and can relieve the pressure exerted on the clamping plate 10 by the pallet.

[0049] In this embodiment, the first fixing block 15 is penetrated by the second bidirectional lead screw 23, and the first fixing plate 19, the second fixing plate 26, and the third fixing plate 28 have the same length.

[0050] The second bidirectional lead screw 23 enables the second slider 25 to move on its surface, facilitating the adjustment of the size.

[0051] In this embodiment, a diversion structure 12 is provided on the top of the base 1. The diversion structure 12 includes a first electric telescopic rod 38. The first electric telescopic rod 38 is arranged on the top of the base 1. One end of the first electric telescopic rod 38 is fixedly connected to a column 39. One end of the column 39 is rotatably connected to a first bottom plate 40. The first bottom plate 40 is connected to a fourth transmission mechanism 42 through a number of support columns 41.

[0052] The diversion structure 12 cooperates with the distribution pallet structure 11 to dock the pallets conveyed by the first transmission mechanism 2, and at the same time can adjust the height position of the fourth transmission mechanism 42 itself.

[0053] In this embodiment, the diversion structure 12 further includes a control component. The control component includes a second bottom plate 43. The second bottom plate 43 is fixedly connected to the column 39. A third motor 44 is arranged at the bottom of the second bottom plate 43. The output shaft of the third motor 44 penetrates the second bottom plate 43 and is fixedly connected to a gear disc 45. The gear disc 45 is meshed with a gear ring 46. The gear ring 46 is fixedly connected to the first bottom plate 40 and is located outside the column 39.

[0054] The control component cooperates with the diversion structure 12 to adjust and limit the angular position of the fourth transmission mechanism 42, enabling the fourth transmission mechanism 42 to convey the pallets to the second transmission mechanism 3 or the third transmission mechanism 4 for diversion work as needed.

[0055] In this embodiment, two groups of supporting auxiliary structures 13 are arranged on the top of the base 1. The supporting auxiliary structure 13 includes two electric telescopic rods 47, a support plate 48 and a baffle 49. The electric telescopic rod 47 is arranged on the top of the base 1, the support plate 48 is fixedly connected to one end of the electric telescopic rod 47, and the baffle 49 is fixedly connected to the support plate 48.

[0056] The supporting auxiliary structure 13 cooperates with the diversion structure 12 to support the pallet on the transmission mechanism four 42, so as to facilitate the angle adjustment of the transmission mechanism four 42 after height adjustment. At the same time, the setting of the baffle 49 can restrict the pallet to prevent it from leaving the range of the transmission mechanism four 42 after being transferred to the transmission mechanism four 42.

[0057] In this embodiment, the second support plate 48 is U-shaped.

[0058] The second support plate 48 is arranged in a U shape to facilitate the angle adjustment of the transmission mechanism 4 42.

[0059] In this embodiment, the clamping plate 10 is composed of a mounting plate and two plug plates, and the positions of the storage box 16, the support plate 17 and the transmission mechanism 2 are adaptively matched.

[0060] The storage box 16 and the support plate 17 can move up and down at the corresponding positions of the transmission mechanism 2 under the action of the cylinder 14.

[0061] It should be noted that the present invention is a pallet distribution mechanism for stacking. Before use, the pallet distribution mechanism is placed in a required location to enable it to reach working conditions.

[0062] Before starting work, start the cylinder 14 to move the storage box 16 upward to a predetermined position, so that the top of the first pallet 17 is higher than the surface height of the first transfer mechanism 2. Then stack a number of pallets on the first pallet 17. The weight of the pallets acts on the first pallet 17 and slides inward into the storage box 16, compressing the spring 18. Then, after adjusting the socket position of the first layer of pallets to a height matching the plug board position of the clamping plate 10 through the cylinder 14, stop. According to the width of the pallets, start the first motor 8 to rotate the first bidirectional lead screw 7, and the first slider 9 drives the clamping plate 10 to move closer to the middle of the first bidirectional lead screw 7. Stop when the plug board of the clamping plate 10 is inserted into the socket of the first layer of pallets and the clamping plate 10 is in contact with the outer side of the pallets. Then, move the storage box 16 back to the initial position through the cylinder 14, that is, the top height of the first pallet 17 is lower than the surface height of the first transfer mechanism 2. At this time, a number of stacked pallets are supported by the plug board of the clamping plate 10, and the first rotating roller 21 is in contact with the outer side of the pallets for limiting. During this process, the clamping plate 10 drives the first support rod 36, the first fixing block 15, and the first fixing plate 19 to move synchronously. The first fixing plate 19 drives the second support rod 37 to move synchronously. The first support plate 34 and the second support plate 35 respectively play a role in limiting and supporting the first support rod 36 and the second support rod 37. The cooperation between the first support rod 36 and the first support plate 34 strengthens the stability and supporting force of the clamping plate 10. Then, according to the length of the pallets, start the second motor 24 to rotate the second bidirectional lead screw 23, so that the second slider 25 drives the second fixing plate 26 to move closer to the middle of the second bidirectional lead screw 23 until the second rotating roller 30 is in contact with the outer side of the pallets and stop. During this process, the second fixing plate 26 drives the third fixing plate 28 to move synchronously through the connecting plate 27. The third fixing plate 28 drives the second fixing frame 29 and the second rotating roller 30 to move synchronously. The second fixing plate 26 also drives the third fixing block 33 to move. The third fixing block 33 moves on the surface of the slide bar 32. The slide bar 32 and the third fixing block 33 make the movement of the second fixing plate 26 more stable. At this time, the stacked pallets are placed at the predetermined position of the pallet distribution mechanism, as Figure 1 shown;

[0063] When it is necessary to distribute the pallet, the cylinder 14 is started to move the storage box 16 upward to a predetermined position and then stop. The top of the first support plate 17 is higher than the surface height of the first transfer mechanism 2. At this time, the top of the first support plate 17 contacts the bottom of the first layer of pallets. The clamping plate 10 is moved away from both ends of the first bidirectional lead screw 7 by the first motor 8, and the insertion plate of the clamping plate 10 is pulled out from the insertion opening of the first layer of pallets. At this time, the gravity of the stacked pallets acts completely on the first support plate 17, and the first support plate 17 slides into the storage box 16, and the spring 18 is compressed. Then, the cylinder 14 is used to move the storage box 16 downward by a certain distance. At this time, the first layer of pallets is higher than the surface of the first transfer mechanism 2, and the insertion opening of the second layer of pallets matches the position of the insertion plate of the clamping plate 10. Then, the first motor 8 is used to move the clamping plate 10 toward the pallet until the insertion plate of the clamping plate 10 is inserted into the insertion opening of the pallet and then stop. At this time, the second layer and above pallets are supported by the insertion plate of the clamping plate 10. Then, the cylinder 14 is started to move the storage box 16 downward until the bottom of the first layer of pallets contacts the surface of the first transfer mechanism 2 and then stop. The first transfer mechanism 2 is started to transport the first layer of pallets;

[0064] In the initial state, the transportation direction of the fourth transfer mechanism 42 is the same as that of the first transfer mechanism 2. The height of the second support plate 48 is slightly lower than the surface height of the first transfer mechanism 2, but higher than the heights of the second transfer mechanism 3 and the third transfer mechanism 4. The first electric telescopic rod 38 is started to move the surface of the fourth transfer mechanism 42 to be at the same height as the surface of the first transfer mechanism 2 and then stop. When the first layer of pallets is transferred from the first transfer mechanism 2 to the fourth transfer mechanism 42, the fourth transfer mechanism 42 acts on the first layer of pallets to continue moving until the first layer of pallets is blocked by the baffle 49 and then stop. Then, the first electric telescopic rod 38 is used to move the fourth transfer mechanism 42 downward with the first layer of pallets until the height of the fourth transfer mechanism 42 is lower than the height of the second support plate 48 and then stop. During this process, the first layer of pallets is supported by the second support plate 48 and stops moving downward. The third motor 44 is started to act on the gear disk 45 to drive the gear ring 46 to engage and move. The gear ring 46 drives the first bottom plate 40, the support column 41 and the fourth transfer mechanism 42 to rotate 90 degrees and then stop. Then, the first electric telescopic rod 38 is used to move the fourth transfer mechanism 42 upward until the fourth transfer mechanism 42 fits with the bottom of the first layer of pallets and then stop. The second electric telescopic rod 47 is started to move the second support plate 48 downward to a predetermined position and then stop. At this time, the second support plate 48 is lower than the surfaces of the second transfer mechanism 3 and the third transfer mechanism 4. The first electric telescopic rod 38 is used to move the fourth transfer mechanism 42 downward with the first layer of pallets to a predetermined position and then stop. At this time, the surfaces of the fourth transfer mechanism 42 and the second transfer mechanism 3 and the third transfer mechanism 4 are flush. The second transfer mechanism 3 and the fourth transfer mechanism 42 can be started as needed to transfer the first layer of pallets to the second transfer mechanism 3 for transportation, or the third transfer mechanism 4 and the fourth transfer mechanism 42 can be started to transfer the first layer of pallets to the third transfer mechanism 4 for transportation;

[0065] When it is necessary to distribute and transfer the pallets on the second layer or other layers, the operation is the same as that for the pallets on the first layer above.
