Description

Technical Field

[0001] The invention relates to the field of material conveying, and in particular to an angle-changing conveying mechanism based on a pallet conveyor. Background Art

[0002] Pallet conveyor is a kind of traction chain conveyor. The traction chain is assembled inside the profile frame of the conveyor line. The pallet can be snapped and placed on the conveyor line. The pallet is transported by the traction chain. The pallet conveyor has high conveying stability and the material in the pallet will not jump randomly. Therefore, pallet conveyor is widely used in the field of small volume material transmission.

[0003] Multiple conveyors in the factory may be docked at an angle (such as vertical docking). This docking position requires a reversing conveying mechanism to perform reversing conveying on the pallet. The existing reversing conveying is generally through a rotating platform, that is, after the pallet is transferred to the rotating platform, the pallet is reversed by the rotating platform. After the reversing docking is completed, the pallet is transferred to another conveyor through the rotating platform for transmission.

[0004] However, during use of the above-mentioned reversing conveying mechanism, after the front conveyor conveys the pallet to the rotating platform, the front conveyor needs to stop running and wait for the rotating platform to transfer the pallet to the rear conveyor and reset the rotating platform before the front conveyor can continue to run. That is, when the pallets on two adjacent conveyors are reversed, intermittent shutdown processing is required, which significantly reduces the efficiency of material transportation and affects the efficiency of subsequent material processing.

[0042] The limiting groove 24 includes a rectangular groove and a right-angled trapezoidal groove, and the rectangular groove is located above the right-angled trapezoidal groove, the width of the rectangular groove is consistent with the height of the right-angled trapezoidal groove, and both are larger than the outer diameter of the limiting rod 25, the length of the rectangular groove is larger than the upper bottom length of the right-angled trapezoidal groove, the upper bottom length of the right-angled trapezoidal groove is larger than the lower bottom length of the right-angled trapezoidal groove, and the rectangular groove and the right-angled trapezoidal groove are coplanar with one end face away from the inclined surface of the right-angled trapezoidal groove, a hinge seat 26 is fixedly provided in the right-angled trapezoidal groove, and a clamping block 27 is elastically hingedly provided on one side of the hinge seat 26 close to the inclined surface of the right-angled trapezoidal groove, the upper end faces of the hinge seat 26 and the clamping block 27, and the lower end face of the limiting groove 24 are coplanar, the clamping block 27 uses the hinge seat 26 as a fulcrum, and elastically swings toward the inclined surface of the right-angled trapezoidal groove, and the end face of the clamping block 27 away from the hinge seat 26 is an inclined surface, and is parallel to the inclined surface of the right-angled trapezoidal groove.

[0043] The deflection component includes a first gear 15 fixedly sleeved on the bottom of the rotating column 14, a tooth plate 16 is meshed on the outer side of the first gear 15, a limiting slider 22 is fixedly provided on the bottom of the fixed cylinder seat 13, and the limiting slider 22 is slidably assembled inside the tooth plate 16, one end of the tooth plate 16 extends out of the outside of the fixed cylinder seat 13, and a top column is fixedly provided on the end of the tooth plate 16 extending out of the fixed cylinder seat 13, a second spring 23 is provided between an end surface of the limiting slider 22 close to the top column and the tooth plate 16, and a transmission member is provided between the tooth plate 16 and the conveyor line body 1, and when the tooth plate 16 moves back and forth, it can mesh with the first gear 15 to allow the rotating column 14 to reciprocate and deflect by a small angle.

[0044] The transmission member includes a gear differential 12, which is located below one of the transmission shafts 3 near the arc plate 9. The position of the gear differential 12, the conveyor line body 1 and the fixed cylinder seat 13 is fixed. One end of the transmission shaft 3 and the input end of the gear differential 12 are assembled through the first transmission gear belt group, and a turntable is fixedly provided at the output end of the gear differential 12. At least one bevel arc push block 17 is fixedly provided at one end of the turntable near the toothed plate 16, and the top column is in sliding contact with the inclined surface of the bevel arc push block 17. When the bevel arc push block 17 follows the turntable to rotate in a circle, the toothed plate 16 can be pushed and released through the top column. The first transmission gear belt group is a combination of synchronous gears and synchronous toothed belts commonly used in the prior art. The synchronous gears and synchronous toothed belts are assembled at the transmission shaft 3 and the input end of the gear differential 12. When the transmission shaft 3 rotates, the gear differential 12 can be triggered.

[0045] Working principle: When the traction chain is in the transmission process, the transmission shaft 3 can trigger the gear differential 12 through the first transmission gear belt group. In this solution, the gear differential 12 has a speed-increasing effect, that is, the slow rotation of the transmission shaft 3 can allow the gear differential 12 to drive the bevel arc push block 17 to rotate quickly, and can push the tooth plate 16 during the rotation process. Under the action of the second spring 23, the bevel arc push block 17 can push the tooth plate 16 to the maximum value and then release it. Under the elastic push of the second spring 23, the tooth plate 16 can be reset, so that the tooth plate 16 drives the first gear 15 to reciprocate with a small angle deflection;

[0046] Reference Figure 7-9 When the rotating column 14 rotates counterclockwise, the upper end surface of the fan-shaped dial 18 on the top of the rotating column 14 is tightly fitted with the lower outer surface of the plurality of balls 11 under the action of the first spring 21, so the deflection of the fan-shaped dial 18 can cause the plurality of balls 11 to rotate, and the rotation direction of the plurality of balls 11 is from the left end to the right end of the arc plate 9, that is, the fan-shaped dial 18 can rub and rotate the plurality of balls 11 at the same time, so as to displace the tray above the arc plate 9;

[0047] When the rotating column 14 rotates counterclockwise to the maximum value, the limit rod 25 can move downward from the leftmost end of the rectangular groove into the right-angled trapezoidal groove under the action of the tension applied by the tension spring 20 to the rotating column 14. At the same time, during the descending process of the rotating column 14, the rotating column 14 can separate the fan-shaped dial 18 from the ball 11 through the first spring 21; at this time, the rotating column 14 rotates, and the limit rod 25 follows the clockwise rotation, and under the guidance of the inclined surface of the right-angled trapezoidal groove, it rises to the rightmost end of the rectangular groove again. Through such reciprocating motion, several balls 11 can be frequently rubbed, thereby realizing the rapid transfer of the pallet above the arc plate 9. Due to the speed-increasing effect of the gear differential 12, the intermittent rotation of the ball 11 makes the pallet moving speed greater than the conveying speed of the traction material strip to transport the pallet.

[0048] Through the above-mentioned reversing conveying method, the pallet can be reversing without stopping and stably.

[0049] Example 2: Please refer to Figure 5 and Figure 6 , this embodiment is a further explanation of the first embodiment, an adjustment mechanism is further provided between the rotating column 14 and the arc plate 9, the adjustment mechanism includes a frame 28 fixedly mounted on the outside of the arc plate 9 in a radial direction, the frame 28 is located in the center of the arc plate 9, two symmetrically distributed connecting rods 31 are slidably arranged inside the frame 28, and the bottoms of the two connecting rods 31 are respectively fixedly suspended with an outer arc plate 35 and an inner arc plate 36, the outer surface of each connecting rod 31 is fixedly sleeved with a rack 29, and the rack 29 and the frame 28 are slidably assembled, the rack 29 is axially rotated with a rotating rod, and the outer surface of the rotating rod is fixedly sleeved with a second gear 30 meshing with the two racks 29, the second gear 30 is located between the two racks 29, and a rotating component is provided between the rotating rod and the rotating column 14, when the second gear 30 located between the two racks 29 reciprocates, the outer arc plate 35 and the inner arc plate 36 can be synchronously and reversely approached or moved away.

[0050] The rotating component includes a slide rod 32 axially slidably inserted on the top of the rotating column 14, the outer surface of the slide rod 32 is fixedly sleeved with a second retaining ring 33, and the outer surface of the second retaining ring 33 is rotatably equipped with a bracket 34, the bracket 34 is fixed to the fixed cylinder seat 13, the slide rod 32 and the top of the rotating rod are driven by a second transmission gear belt group, the rotating column 14 can be synchronously rotated with the second gear 30 through the second transmission gear belt group, the second transmission gear belt group is also a combination of synchronous gears and synchronous toothed belts in the prior art, the synchronous gears and synchronous toothed belts are assembled on the top of the slide rod 32 and the rotating rod, so that the two can rotate synchronously.

[0051] In this embodiment: due to the large area of ​​the arc plate 9, the ball 11 may deviate during the process of transferring the pallet. For this reason, in this solution, when the rotating column 14 rotates back and forth, the second transmission gear belt group can drive the second gear 30 to rotate back and forth. Through the engagement of the second gear 30 with the two racks 29, the two connecting rods 31 can move the outer arc plate 35 and the inner arc plate 36 in a zooming movement, that is, the reciprocating movement of shrinking and expanding the distance between the two, thereby adjusting the moving direction of the pallet located above the arc plate 9, and further ensuring the accuracy of the pallet reversing transfer.
