[0045] The utility model discloses a kind of rotary pusher, rotary pusher includes base body 01, rotating seat 10, fork arm 20, support part 30, clamping assembly 40 and limiting assembly 50.Base body 01 is connected with rotating seat 10 by bearing, allow rotating seat 10 to freely rotate on it.Rotating seat 10 is equipped with motor or hydraulic motor, provides rotating power for rotating seat 10.Fork arm 20 is installed on rotating seat 10, its position and support part 30 are spaced apart along height direction and interval can be adjusted by air cylinder or hydraulic cylinder.Support part 30 is used to support goods after fork arm 20 lifts goods from pallet, prevent goods from falling in the rotation process.The bearing capacity of support part 30 needs to be matched with fork arm 20, to ensure that maximum load can be supported.Clamping assembly 40 is located between fork arm 20 and support part 30 on rotating seat 10, for fixing goods on rotating seat 10 by lateral compression after goods are lifted by fork arm 20, prevent the movement of goods in the rotation process.

[0046] Specifically, when operating rotary pusher, first, motor or hydraulic motor is started, rotating seat 10 is rotated, so that fork arm 20 is located below, and support part 30 is located above.Then, forklift drives fork arm 20 to insert under pallet, fork arm 20 rises, and goods are lifted to support part 30.At this time, lateral compression plate moves inward to clamp and fix goods.After that, motor or hydraulic motor is started again, rotating seat 10 is rotated by 180 degrees, fork arm 20 is in upper position, and support part 30 is in lower position, and goods are separated from pallet.Next, lateral compression plate continues to work, and goods are compressed to appropriate size.Finally, forklift enters carriage, hydraulic lifter is started, and push-out plate is pushed to send goods into carriage.

[0047] Further, the limiting assembly 50 is located on the side of the rotating seat 10 away from the material, and the limiting assembly 50 comprises a limiting gear 51, a limiting rack 52, and a stop portion 53. The limiting gear 51 rotates synchronously with the rotating shaft of the rotating seat 10, the limiting rack 52 is movably arranged on the base body 01, the limiting rack 52 cooperates with the limiting gear 51, and the limiting gear 51 is used to drive the limiting rack 52 to rotate. The stop portion 53 is arranged on the base body 01, the stop portion 53 is located on the moving path of the limiting rack 52, and the stop portion 53 cooperates with the limiting rack 52 to limit the rotating angle of the rotating seat 10.

[0048] In the embodiment, the limiting gear 51 is coaxially connected with the rotating shaft in the rotating seat 10, so as to ensure synchronous rotation. The limiting rack 52 adopts a movable structure, is fixed on the base body 01 through a guide rail or a sliding groove 102, and can stably move along a predetermined path. The stop portion 53 is arranged on the base body 01 and located at both ends of the moving path of the limiting rack 52, and is used in cooperation with the limiting rack 52 to limit the rotating angle of the rotating seat 10. When the rotating seat 10 rotates to 180°, the limiting rack 52 will be in contact with the stop portion 53 on one side, so as to prevent the limiting rack 52 from continuing to move, thereby achieving the locking of the rotating disc angle and preventing excessive rotation. Similarly, when the rotating seat 10 needs to return to the original position, the limiting rack 52 will be in contact with the stop portion 53 on the other side, so as to ensure that the rotating seat 10 can accurately return to the starting position, and the rotating disc is prevented from being skewed.

[0049] Specifically, the meshing of the limiting rack 52 and the limiting gear 51 needs to ensure accurate cooperation between the two, so that the limiting gear 51 can accurately drive the limiting rack 52 when rotating. The moving path of the limiting rack 52 needs to be adapted to the rotating angle of the rotating seat 10, so as to ensure that the limiting rack 52 can be accurately aligned to the stop portion 53 when rotating to 180°.

[0050] Further, the limiting assembly 50 further comprises a stop frame 54 fixedly arranged on the base body 01, the stop frame 54 is located on the side of the rotating seat 10 away from the material, and the stop frame 54 comprises a connecting piece 541 and two limiting pieces 542, the connecting piece 541 extends along the moving direction of the limiting rack 52, the two limiting pieces 542 are arranged at two ends of the connecting piece 541 respectively, the limiting rack 52 is located between the two limiting pieces 542, and the two limiting pieces 542 are used to cooperate with the limiting rack 52 to stop.

[0051] In the embodiment, the limiting assembly 50 comprises a stop frame 54 fixed on the base body 01. The stop frame 54 is located on the side of the rotating seat 10 away from the material, so that the stop frame 54 does not interfere with the goods or the pallet when the rotating disc rotates by 180°, and the rotating range of the rotating disc can be effectively limited. The stop frame 54 comprises a connecting piece 541 and two limiting pieces 542. The connecting piece 541 extends along the moving direction of the limiting rack 52, and serves to support and connect the two limiting pieces 542. The two limiting pieces 542 are respectively arranged at the two ends of the connecting piece 541, and form a "U"-shaped structure, so as to ensure that the limiting rack 52 is always located in the center of the "U"-shaped structure when moving, thereby avoiding deviation.

[0052] Further, the stop frame 54 further comprises a guide piece 543 arranged on the connecting piece 541 and located between the two limiting pieces 542. The guide piece 543 has a guide groove 5431, and the extending direction of the guide groove 5431 is the same as that of the connecting piece 541. The limiting rack 52 is movably arranged in the guide groove 5431, and the guide groove 5431 is used for guiding the movement of the limiting rack 52. In the embodiment, the guide piece 543 is arranged on the connecting piece 541 and located between the two limiting pieces 542. The guide piece 543 is usually in a strip shape and has a specially designed guide groove 5431. The extending direction of the guide groove 5431 is consistent with that of the connecting piece 541. The above structure can ensure that the limiting rack 52 can move accurately along the preset path when moving, and deviation or shaking is avoided.

[0053] Further, the rotating ejector further comprises a rotating driving piece 101 arranged on the base body 01 and drivingly connected with the rotating seat 10. In the embodiment, the rotating driving piece 101 is arranged on the base body 01 and drivingly connected with the rotating seat 10, so as to provide a rotating driving force for the rotating seat 10 and ensure accurate execution of the rotating action. Specifically, the rotating driving piece 101 can be, but is not limited to, a gear, a chain, a belt or a direct electric driving mode, and is preferably a gear motor, which can provide high-torque and high-precision rotating motion. Through gear transmission, the rotating seat 10 is driven to rotate.

[0054] As Figure 4As shown, the clamping assembly 40 includes two clamping plates 41 and a clamping drive 42. The two clamping plates 41 are movably arranged on the rotating seat 10 and are located on the same side as the fork arm 20 and the supporting part 30. The spacing between the two clamping plates 41 can be adjusted, and a placement area is formed between the two clamping plates 41, the fork arm 20 and the supporting part 30 for placing materials. The clamping drive 42 is arranged on the side of the rotating seat 10 away from the fork arm 20, and the clamping drive 42 is drivingly connected with the two clamping plates 41 to drive the two clamping plates 41 to move closer to or away from each other.

[0055] In this embodiment, the two clamping plates 41 are both mounted on the rotating seat 10 and located on the same side as the fork arm 20 and the supporting part 30. The spacing between the two clamping plates 41 can be adjusted to form a placement area suitable for different sizes of materials. The clamping drive 42 is arranged on the side of the rotating seat 10 away from the fork arm 20 to avoid interference with the material handling area. The clamping drive 42 can be a hydraulic cylinder or a pneumatic cylinder, or a linear drive device such as an electric push rod. When the clamping drive 42 is actuated, the two clamping plates 41 can move inward or outward synchronously to clamp or release the material. The thrust and stroke of the clamping drive 42 need to be matched with the movement range of the clamping plates 41 to ensure that materials of various sizes can be stably clamped.

[0056] Specifically, when the fork arm 20 is inserted into the tray and lifts the material to the supporting part 30, the two clamping plates 41 are in the outermost position, forming an open placement area to allow the material to enter. After the material is placed in position, the clamping drive 42 is started to push the two clamping plates 41 inward until they come into contact with the sides of the material and exert sufficient pressure to keep the material stable during rotation.

[0057] Further, the fork arm 20 is movably arranged on the rotating seat 10, and the rotating ejector further comprises a lifting driving member 201 in driving connection with the fork arm 20 to drive the fork arm 20 to approach or move away from the supporting part 30. In the embodiment, the fork arm 20 is not fixed at a certain position of the rotating seat 10, but is movably arranged on the rotating seat 10 through a sliding mechanism or a guide device. The above structure can make the fork arm 20 move in the vertical direction to adapt to trays or cargos of different heights. The lifting driving member 201 is usually a hydraulic cylinder, a pneumatic cylinder or an electric push rod, one end of which is fixed on the rotating seat 10 and the other end of which is in driving connection with the fork arm 20. The lifting driving member 201 can accurately control the lifting speed and position of the fork arm 20 when moving, so as to ensure that the fork arm 20 can be stably inserted from below the tray, lift the cargo to the supporting part 30, then separate the cargo from the tray and send the cargo to the target position. Meanwhile, the moving range of the fork arm 20 should be adapted to the height of the supporting part 30. When the fork arm 20 is inserted below the tray, the supporting part 30 should be located at a proper distance above the fork arm 20 to avoid interference with the cargo during the lifting of the fork arm 20. When the fork arm 20 is lifted to the maximum height, a sufficient gap should be kept between the fork arm 20 and the supporting part 30 to facilitate the compression operation of the cargo by the clamping plate 41 driven by the double-head pneumatic cylinder.

[0058] Further, a sliding groove 102 is arranged on the side of the rotating seat 10 where the fork arm 20 is located, the extending direction of the sliding groove 102 is the same as the moving direction of the fork arm 20, a guide block 1021 is arranged on the side of the fork arm 20 close to the rotating seat 10, the guide block 1021 is movably arranged in the sliding groove 102, and the sliding groove 102 cooperates with the guide block 1021 to guide; and / or, a guide hole 103 is arranged on the side of the rotating seat 10 where the fork arm 20 is located, and a guide rod 1031 is arranged on the end of the fork arm 20 close to the rotating seat 10, the guide rod 1031 extends along the moving direction of the fork arm 20, the guide rod 1031 is movably arranged in the guide hole 103, and the guide hole 103 cooperates with the guide rod to guide.

[0059] In the embodiment, the sliding groove 102 extends along the moving direction of the fork arm 20 on the side of the rotating seat 10 where the fork arm 20 is located. The width of the sliding groove 102 is matched with the guide block 1021 on the fork arm 20, so as to ensure that the guide block 1021 can smoothly move in the sliding groove 102. The guide block 1021 and the fork arm 20 can be connected through welding, bolt fixing or the like to ensure the strength and stability therebetween.

[0060] In another embodiment, a guide hole 103 is arranged on the side of the rotating seat 10 where the fork arm 20 is located, and the guide hole 103 is arranged along the moving direction of the fork arm 20, and is used to cooperate with the guide rod 1031 on the fork arm 20. The diameter of the guide hole 103 is slightly larger than the diameter of the guide rod 1031, so as to allow the guide rod 1031 to move freely in the guide hole 103, while reducing the friction therebetween. The guide rod 1031 extends along the moving direction of the fork arm 20, and it is necessary to ensure that the guide rod 1031 and the fork arm 20 have sufficient strength and rigidity to withstand the force generated by the air cylinder or hydraulic cylinder when driving the fork arm 20 to move. The use of the above-mentioned guide structure can reduce the swing of the fork arm 20 when moving, enhance the stability, and also facilitate the maintenance and adjustment of the fork arm 20.

[0062] In the embodiment, the fork arm 20 is composed of the main rod 202 and a plurality of fork rods 203 arranged at intervals, the main rod 202 is connected with the rotating seat 10, so as to ensure that the fork arm 20 can rotate together with the rotating seat 10. The number and layout of the fork rods 203 need to be designed according to the size and weight of the goods, and generally the fork rods 203 are uniformly arranged at intervals along the extension direction of the main rod 202, which can ensure the stability of the goods when being forked, and avoid the goods from tilting or falling due to uneven distribution of the fork rods 203. The supporting part 30 is composed of a plurality of supporting plates, and the number of the supporting plates should be greater than the number of the fork rods 203, so as to provide a larger supporting area, and ensure the stability and safety of the goods during rotation. The supporting plates are also arranged at intervals on the rotating seat 10 along the extension direction of the main rod 202, and form an upper-lower corresponding relationship with the fork rods 203. When the fork arm 20 forks the goods from the pallet, the goods will be placed on the supporting plates, and the size and strength of the supporting plates need to meet the needs of bearing the goods, so as to avoid deformation or damage under heavy load conditions.

The pusher 60 needs to have sufficient strength and rigidity to withstand the weight and thrust of the material during pushing, and its surface treatment needs to be smooth to reduce friction with the material and prevent damage to the material.

[0065] Specifically, the pusher 60 and the supporting part 30 should be arranged on the same side of the rotating seat 10, so that the pusher 60 can smoothly push the goods on the supporting part 30 after the rotating seat 10 is rotated by 180°. The distance between the pusher 60 and the supporting part 30 needs to be adjusted according to the size and weight of the material to ensure the stability of the material during pushing.
