DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , an embodiment of the utility model provides a pallet recovery system.

[0028] like Figures 1 to 3 As shown, an embodiment of the utility model provides a pallet recovery system, comprising: a conveying mechanism 10; a guide mechanism 20, the guide mechanism 20 is located on the upper side of the conveying mechanism 10 and is adjacent to the conveying mechanism 10, the guide mechanism 20 forms a guide channel for the pallet to pass through; a gripping mechanism 30, the gripping mechanism 30 comprises a mechanical arm 301 and a clamping assembly 302, the clamping assembly 302 comprises a fixed seat 3021 and a clamping portion 3022, the fixed seat 3021 is connected to the end of the mechanical arm 301, the clamping portion 3022 is arranged on the fixed seat 3021 and there are at least two of them, at least two clamping portions 3022 are arranged on opposite sides of the fixed seat 3021, and can be close to each other for clamping both sides of the pallet.

[0029] In the above technical solution, the robot arm 301 is rotated and positioned, and then the two sides of the pallet are clamped by the clamping assembly 302, and it is clamped from the conveyor belt to the conveying mechanism 10 to achieve stable transportation. At the same time, the guide mechanism 20 can guide the pallet when it enters to prevent it from deflecting, thereby achieving the purpose of avoiding the impact deformation of the pallet.

[0030] The utility model is further configured as follows: the conveying mechanism 10 includes a bracket 101 and a conveying component 102, and the conveying component 102 is arranged on the bracket 101;

[0031] In the above technical scheme, the top surface of the bracket 101 is horizontal, and the conveying component 102 is placed parallel to the top surface of the bracket 101, so as to prevent the pallet from actively sliding on the conveying component 102 due to gravity. During the actual installation process, adjustable supporting feet can be set around the bottom of the bracket 101. After the bracket 101 is placed on the installation plane, the horizontality of the top surface of the bracket 101 can be adjusted by adjusting the supporting feet, and a spirit level can be used for measurement. At the same time, the conveying speed of the conveying component 102 is adjustable, so that the conveying speed of the pallet can be controlled. During actual use, the conveying component 102 can use a variable speed motor as power and a roller group as a transmission component. Chain transmission is used between multiple groups of roller groups. At the same time, inclined anti-skid grooves can be symmetrically opened on the outside of the rollers. The angle direction of the anti-skid grooves on both sides is consistent with the conveying direction of the conveying component 102, so that the anti-skid grooves can be used to guide the pallet and make it roughly centered during the forward movement.

[0032] The guide mechanism 20 includes a first guide plate 201 and a second guide plate 202 . The first guide plate 201 and the second guide plate 202 are disposed on both sides of the conveying component 102 and connected to the bracket 101 . The first guide plate 201 and the second guide plate 202 jointly define a guide channel.

[0033] In the above technical scheme, the first guide plate 201 and the second guide plate 202 are symmetrically arranged with respect to the center of the bracket 101. The first guide plate 201 and the second guide plate 202 are made of rigid parts and are rust-proofed or made of stainless steel. A protective pad can be provided on the side of the first guide plate 201 and the second guide plate 202 close to the center of the bracket 101. The protective pad should have wear-resistant and anti-collision properties. The protective pad covers the entire inner side of the first guide plate 201 and the second guide plate 202, so as to avoid collision damage between the tray and the inner side of the first guide plate 201 and the second guide plate 202. The first guide plate 201 and the second guide plate 202 in this scheme have a simple structure and are easy to install, which not only reduces the manufacturing cost but also facilitates disassembly and maintenance.

[0034] Specifically, at least two groups of parallel long holes can be vertically opened at the bottom of the first guide plate 201 and the second guide plate 202 on one side away from the center of the bracket 101. The extension direction of the long holes is perpendicular to the conveying direction of the conveying mechanism 10. At the same time, bolts are inserted into the long holes to fix them to the bracket 101, and the bracket 101 has threaded holes matching them. In this way, the long holes can be used to adjust the distance between the first guide plate 201 and the second guide plate 202 according to the size of the pallet, thereby improving the adaptability of the guide mechanism 20.

[0035] At the same time, the guide channel formed between the first guide plate 201 and the second guide plate 202 has a larger opening at the front end of the bracket 101, which makes it easier for the tray to enter the guide channel. Even if the tray is offset to a certain extent, the front end opening can still be used to ensure its stable entry, and the size of the front end opening can be adjusted according to actual needs. However, the maximum angle between the front ends of the first guide plate 201 and the second guide plate 202 should not exceed 90 degrees, otherwise it cannot be guaranteed that the first guide plate 201 and the second guide plate 202 have sufficient support angles, which may cause the tray to get stuck.

[0036] The utility model is further configured as follows: a reserved space is provided between the end of the first guide plate 201 and the end of the second guide plate 202 and the end of the bracket 101 .

[0037] In the above technical solution, both sides of the reserved space are open, and the robot arm 301 controls the clamping assembly 302 to move to the top of the pallet and clamp it, and then places it in the reserved space. Multiple groups of pallets are stacked. When the number of pallets reaches a certain number, workers manually remove the sorted pallets from the reserved space. In actual use, infrared rays can be used to detect the position of the pallet. When the pallet is about to reach the reserved space, the robot arm 301 is controlled to start clamping the pallet, thereby preventing collisions between pallets.

[0038] The utility model is further configured such that: in the conveying direction of the conveying mechanism 10 , the size of the reserved space is greater than or equal to the size of the clamping portion 3022 .

[0039] The utility model is further configured as follows: a limit piece 101a is provided at the end of the bracket 101 , the limit piece 101a protrudes from the upper surface of the conveying component 102 , the limit piece 101a is a baffle, and the extension direction of the baffle is perpendicular to the conveying direction of the conveying mechanism 10 .

[0040] In the above technical solution, the limit member 101a can be a whole plate or multiple small plates placed at intervals. The length of the limit member 101a can at least ensure that the pallet is blocked and prevented from falling. The limit member 101a can be made of stainless steel or be rust-proofed. At the same time, a protective pad can be set on the side of the limit member 101a close to the conveying component 102, and the protective pad covers the entire front of the limit member 101a, so as to prevent the pallet from rigidly colliding with the conveying component 102.

[0041] like Figures 4 to 5 As shown, the utility model is further configured as follows: the clamping portion 3022 includes a connecting plate 3022a and a clamping member 3022b, the connecting plate 3022a is connected to the fixing seat 3021, and there are at least two clamping members 3022b, which are spaced apart along the conveying direction of the conveying mechanism 10.

[0042] In the above technical solution, multiple groups of clamping parts 3022 are symmetrically provided on both sides of the fixed seat 3021, the connecting plate 3022a is slidably connected to the fixed seat 3021, and the sliding direction of the connecting plate 3022a is consistent with the extension direction of the fixed seat 3021. At the same time, the sliding direction of the connecting plate 3022a is perpendicular to the conveying direction of the conveying component 102, and the distance between the two groups of clamping members 3022b farthest away on the same side of the fixed seat 3021 is less than or equal to the width of the pallet, so that it can be ensured that the clamping members 3022b on the same side of the fixed seat 3021 can act on the pallet.

[0043] The utility model is further configured as follows: the clamping portion 3022 further includes a flexible member 3022c, and the flexible member 3022c is arranged on one side of the clamping member 3022b close to the center of the fixing seat 3021.

[0044] In the above technical solution, the flexible member 3022c may be a rubber pad or a silicone pad. The flexible member 3022c may be fixed to the surface of the clamping member 3022b in a manner other than gluing. The flexible member 3022c may prevent the rigid clamping member 3022b from directly contacting the pallet and causing damage to the pallet.

[0045] The utility model is further configured as follows: a support portion 3022d is protruded from one end of the flexible member 3022c close to the center of the fixing seat 3021.

[0046] In the above technical solution, the support part 3022d can hold up the bottom of the pallet, and the two ends of the clamping member 3022b do not need to maintain a large clamping force with the pallet to hold up the pallet. The support part 3022d is detachably arranged on the clamping member 3022b and the flexible member 3022c. In actual application, whether to install it can be selected according to needs, and the distance from the top surface of the support part 3022d to the bottom surface of the connecting plate 3022a is greater than the thickness of a pallet. At the same time, vertical long holes can be opened in the clamping member 3022b and the flexible member 3022c, and the support part 3022d is fixed to the clamping member 3022b and the flexible member 3022c by bolts. In this way, the vertical height of the support part 3022d can be adjusted to adapt to pallets of different thicknesses.

[0047] The utility model is further configured as follows: the clamping assembly 302 also includes a telescopic driving member 3023, at least one clamping portion 3022 is connected to the telescopic driving member 3023, and the telescopic driving member 3023 is arranged on the fixed seat 3021 to drive the clamping portions 3022 on opposite sides of the fixed seat 3021 to move closer to or away from each other.

[0048] In the above technical solution, the telescopic drive member 3023 is controlled by an external control chip, and the position of the pallet is monitored by infrared rays during the actual working process. When the pallet reaches the preset position, the external controller controls the robot arm 301 to start, and the robot arm 301 is programmed in advance so that after receiving the command, the end of the robot arm 301 quickly moves to the specified position, that is, directly above the pallet, and then the end of the robot arm 301 drives the fixed seat 3021 to descend. At the same time, the external controller controls the telescopic drive member 3023 to extend, so that the clamping parts 3022 on both sides are away from each other, and the distance between the two groups of clamping parts 3022 is greater than the length of the pallet. When the support part 3022d is located below the pallet, the robot arm 301 stops descending, and the stop height of the robot arm 301 is preset in the program in advance. Then the external controller controls the telescopic drive member 3023 to retract, thereby utilizing the clamping parts 302 on both sides. 2b clamps the pallet, at which time the support part 3022d is located under the pallet and supports the pallet (the bottom of the actual pallet is mostly an arc-shaped structure, so the support part 3022d can lift it from the bottom of the pallet, except that some pallets have a folded edge on the top, so that the support part 3022d can still be used to extend into the folded edge of the pallet to lift the pallet), and finally the robot arm 301 starts and transfers the pallet to the reserved space. When the robot arm 301 reaches the top of the reserved space, the external controller controls the telescopic drive part 3023 to extend, and at this time the pallet falls off from between the clamping parts 3022b and is placed in the reserved space. This is repeated, and multiple groups of pallets are stacked and placed. When the number of pallets reaches a certain number, the workers manually remove the sorted pallets from the reserved space to realize the recycling of the pallets. During the entire recycling process, the pallets will not be piled up on the conveyor belt and the conveying component 102, thereby effectively avoiding collisions between pallets.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
