Description

Technical Field

[0001] The utility model relates to the technical field of non-standard automation equipment, in particular to an automatic pallet transfer mechanism. Background Art

[0002] Pallets are a very common workpiece carrier. They are widely used in large-scale production processes, especially on assembly lines. During the workpiece production process, workers usually manually place pallets at the starting position of the assembly line, and then transport the pallets and the workpieces they carry to the corresponding workstations through a conveyor system. However, this method of manually transporting pallets from shelves to the assembly line is time-consuming and labor-intensive, and the rhythm of manual pallet transport is difficult to accurately match the work rhythm of the assembly line, which may lead to uneven workpiece loading speeds, that is, the loading may be too fast or too slow, which in turn affects the efficiency and smoothness of the overall production line.

[0009] In the above-mentioned automatic pallet transfer mechanism, a hollow portion is provided on the receiving member, and the width of the hollow portion is greater than the width of the conveyor belt and smaller than the width of the pallet, so that the pallet can be detached from the receiving member and placed on the conveyor belt when the receiving member drives the pallet to move in the direction of the conveyor belt.

[0010] The above-mentioned automatic pallet transfer mechanism also includes a support plate, which is rotatably arranged on the side of the receiving member. The support plate has a first working state in which the support plate is flush with the end face of the receiving member, and a second working state in which the end face is arranged at an angle to the end face of the receiving member. When the support plate is in the first working state, it is used to fill the hollow part and provide support for the pallet on the receiving member. When the support plate is in the second working state, it is used to provide a avoidance when the conveyor belt receives the pallet.

The pushing rod has an avoidance portion and a pushing portion. In the horizontal direction, the distance between the avoidance portion and the roller is greater than the distance between the pushing portion and the roller. The support plate can be in the second working state due to the movable abutment between the roller and the avoidance portion, and can be in the first working state due to the abutment between the roller and the pushing portion.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] A pallet automatic transfer mechanism comprises: a frame 1, on which a first placement area 2 and a second placement area 3 are arranged; a support block 4, which is movably arranged in the first placement area 2 along the vertical direction, and a pallet 5 is stacked on the support block 4; a pusher 6, which is movably arranged above the frame 1, and the pallet 5 on the support block 4 is located on the moving path of the pusher 6; a receiving member 7, which is movably arranged in the second placement area 3 along the vertical direction; a conveyor belt 8, which is horizontally arranged on the side of the frame 1, one end of the conveyor belt 8 extends into the second placement area 3 and is located on the moving path of the receiving member 7, and the receiving member 7 is used to receive the pallet 5 pushed by the pusher 6 and transport it to the conveyor belt 8.

[0034] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 1 to 4 As shown, the overall structure of the rack 1 is similar to a cube, which is composed of a base plate, pillars vertically fixed on the base plate, and a crossbeam at the top. The pillars divide the inside of the rack 1 into two areas: a first placement area 2 and a second placement area 3. In the initial state, the support block 4 is located at the bottom of the first placement area 2, and the upper end surface of the support block 4 is stacked with empty pallets 5 layer by layer; and the receiving member 7 is placed on the top of the second placement area 3, and is just below the top empty pallet 5 of the support block 4, while ensuring that the top height of the receiving member 7 is not lower than the bottom of the second empty pallet 5 from the top.

[0035] During operation, first, the pusher 6 pushes the empty pallet 5 on the top layer of the support block 4 onto the receiving member 7. Once the receiving member 7 receives the pallet 5, the receiving member 7 drives the pallet 5 to move downward, allowing it to land smoothly on the conveyor belt 8, and then the conveyor belt 8 transports the pallet 5 to a preset position, thereby successfully completing the transfer process of the pallet 5. After the pusher 6 removes the pallet 5 on the top layer of the support block 4, the support block 4 rises in the vertical direction, thereby lifting the pallet 5 originally on the second layer, so that it can be pushed by the pusher 6 onto the receiving member 7 for the next step.

[0036] In this solution, the pallets 5 are stacked layer by layer in the vertical direction by the support blocks 4, and the pushing members 6 move the pallets 5 one by one to the receiving members 7. Then, the pallets 5 are transferred to the conveyor belt 8 through the vertical transmission function of the receiving members 7. Finally, with the help of the horizontal transmission capacity of the conveyor belt 8, the pallets 5 are accurately delivered to the preset position. In this way, the transfer process of the pallets 5 is completely realized, thereby effectively ensuring the continuity and smoothness of the entire production line.

[0037] In this solution, in order to ensure that the tray 5 can be smoothly transferred from the receiving member 7 to the conveyor belt 8 when the receiving member 7 is lowered, a hollow area 9 is specially designed on the receiving member 7. The width of the hollow portion 9 is greater than the width of the conveyor belt 8, but less than the width of the tray 5. In the process of the receiving member 7 driving the tray 5 to move in the direction of the conveyor belt 8, the conveyor belt 8 will rise relatively and pass through the hollow portion 9 on the receiving member 7, pass under the hollow portion 9 and lift up the tray 5 on the receiving member 7. In this way, the tray 5 can be successfully separated from the receiving member 7 and placed on the conveyor belt 8.

[0038] After the pushing member 6 pushes the empty pallet 5 onto the receiving member 7, the rest of the transfer mechanism (not shown in the figure) will place the workpieces on the empty pallet 5. When the pallet 5 is made of soft materials such as foam, due to the presence of the hollow portion 9 in the receiving member 7, the middle portion of the pallet 5 will sink downward under the action of the gravity of the workpiece. In extreme cases, there is a risk that the pallet 5 will pass through the hollow portion 9 and fall.

[0039] In order to solve the above problems, the present solution also includes a support plate 10, which is rotatably arranged on the side of the receiving member 7. The support plate 10 has a first working state in which the support plate 10 is flush with the end face of the receiving member 7, and a second working state in which the end face is arranged at an angle to the end face of the receiving member 7. When the support plate 10 is in the first working state, it is used to fill the hollow portion 9 and provide support for the tray 5 on the receiving member 7 to prevent the tray 5 from falling. When the support plate 10 is in the second working state, it is used to provide a avoidance when the conveyor belt 8 receives the tray 5, so that the conveyor belt 8 can pass through the receiving member 7 normally and transfer the tray 5 on the receiving member 7 to the conveyor belt 8.

[0040] In addition, in order to realize the switching of the support plate 10 between the first working state and the second working state, the present solution also includes: a support frame 11, which is fixed on the receiving member 7; a first rotating shaft 12, which is rotatably arranged on the support frame 11, and one end of the support plate 10 is fixed on the first rotating shaft 12; a first pulley 13, which is fixed on the first rotating shaft 12; a second rotating shaft 14, which is rotatably arranged on the support frame 11 and arranged parallel to the first rotating shaft 12; a second pulley 15, which is fixed on the second rotating shaft 14, and the first pulley 13 and the second pulley 15 are connected by a belt 16; a connecting rod 17, a connecting rod 17 is fixed at both ends of the second rotating shaft 14 along the axial direction, and a connecting shaft 18 is fixed between the two connecting rods 17; a roller 19, which The rolling part is set on the connecting shaft 18; an elastic member 20, one end of which is fixed on the connecting rod 17, and the other end of the elastic member 20 is connected to the support frame 11, and the elastic member 20 can be in a stretched state because the support plate 10 is in the first working state; a pushing rod 21, which is vertically arranged on the frame 1 and is between the first placement area 2 and the second placement area 3, the pushing rod 21 and the roller 19 are movably abutted, and the pushing rod 21 has a avoiding part 22 and a pushing part 23. In the horizontal direction, the distance between the avoiding part 22 and the roller 19 is greater than the distance between the pushing part 23 and the roller 19, and the support plate 10 can be in the second working state due to the active abutment between the roller 19 and the avoiding part 22, and is in the first working state due to the abutment between the roller 19 and the pushing part 23.

[0041] When the receiving member 7 moves to the top position of the frame 1, the roller 19 is in close contact with the pushing portion 23 of the pushing rod 21. At this time, the elastic member 20 is in a stretched state, and the support plate 10 is kept in the horizontal first working state. As the receiving member 7 moves toward the conveyor belt 8, the roller 19 gradually changes from being in contact with the pushing portion 23 to being in contact with the avoidance portion 22. At this time, since the distance between the avoidance portion 22 and the roller 19 is greater than the distance between the pushing portion 23 and the roller 19, under the action of the elastic member 20, the second rotating shaft 14 will drive the connecting rod 17, the connecting shaft 18 and the roller 19 to rotate around the axis of the second rotating shaft 14 according to Figure 4 Rotate in the counter-clockwise direction.

[0042] Since the second rotating shaft 14 is connected to the first rotating shaft 12 through the first pulley 13, the second pulley 15 and the belt 16, when the second rotating shaft 14 rotates counterclockwise, the first rotating shaft 12 will also rotate in the same direction, that is, counterclockwise. This action will cause the support plate 10 to switch from the first working state to the second working state. The elastic member 20 preferably uses a tension spring as a component to achieve this function. When the support plate 10 is in the second working state, the angle between the support plate 10 and the receiving member 7 is 90°.

[0043] More preferably, the receiving member 7 is C-shaped.

[0044] Finally, the present scheme also includes: a first driving member 24, which is vertically arranged in the first placement area 2, and a first movable seat 25 is movably arranged on the first driving member 24, and the support block 4 is connected to the first movable seat 25, which is used to drive the support block 4 to move in the vertical direction; a second driving member 26, which is vertically arranged in the second placement area 3, and a second movable seat 27 is movably arranged on the second driving member 26, and the receiving member 7 is connected to the second movable seat 27, which is used to drive the receiving member 7 to move in the vertical direction; a third driving member 28, which is horizontally arranged on the top of the frame 1, and a third movable seat 29 is movably arranged on the third driving member 28, and the pushing member 6 is connected to the third movable seat 29, which is used to drive the pushing member 6 to move in the horizontal direction.

[0045] The first driving member 24, the second driving member 26 and the third driving member 28 are preferably linear guides. The first driving member 24 drives the support block 4 to move in the first placement area 2 through the first moving seat 25, the second driving member 26 drives the push block to move in the second placement area 3 through the second moving seat 27, and the third driving member 28 drives the push member 6 to move in the horizontal direction through the third moving seat 29.
