Description

Technical Field

[0001] The invention belongs to the technical field of logistics sorting, and in particular relates to a pendulum wheel sorting machine. Background Art

[0002] In recent years, the rapid development of express delivery and e-commerce has accelerated the arrival of unmanned and automated logistics. The pendulum sorter can automatically sort the passing objects according to their destination, transportation method, etc. by switching at different angles according to the commands issued by the front-end management system.

[0003] The wheel sorter can also process objects by diverting, merging, and sorting them. It is widely used in the express logistics industry due to its advantages of fast sorting speed and low error rate. Nowadays, the diversity of express parcels and the continuous increase in the share of heavy cargo parcels make it difficult for traditional wheel sorters to meet today's sorting requirements.

[0004] A balance wheel sorting machine generally includes a plurality of balance wheel units that can convey objects and a swing device that drives the balance wheel units to swing. However, the balance wheel units in the prior art always maintain constant power transmission regardless of the weight of the conveyed objects during conveying, which does not meet the energy-saving requirements and also increases the conveying cost. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a pendulum wheel sorting machine which can adaptively adjust the driving power according to the load of the objects.

[0006] The object of the present invention can be achieved through the following technical solutions: a balance wheel sorting machine, including a frame, the frame is provided with a plurality of balance wheel mechanisms, the balance wheel mechanism includes a balance wheel bracket rotatable on the frame, a first support shaft provided on the balance wheel bracket, and a conveying wheel provided on the first support shaft and capable of carrying and conveying objects, a first transmission roller is provided below the conveying wheel, a first driving mechanism for driving the first transmission roller to rotate is provided below the first transmission roller, a connecting bracket is hingedly connected to the side of the balance wheel bracket, a second driving mechanism for driving the connecting bracket to move forward or backward is provided below the connecting bracket, a first transmission mechanism is provided between the conveying wheel and the first transmission roller, the first transmission roller can drive the conveying wheel to rotate around the first fixed axis as the axis through the first transmission mechanism, the conveying wheel and the first transmission roller are coupled by providing the first transmission mechanism, and the interaction force between the conveying wheel and the first transmission roller increases with the increase of the load on the conveying wheel, and a clearance space for the connecting bracket to move along the left and right directions is provided between the connecting bracket and the second driving mechanism.

[0007] The balance wheel bracket is used to install the first support shaft, the first support shaft is used to install the conveying wheel, the first driving mechanism is used to drive the first transmission roller to rotate, the first transmission roller drives the conveying wheel to rotate through the first transmission mechanism, and since the conveying wheel and the first transmission roller are coupled through the first transmission mechanism, the acting force between the conveying wheel and the first transmission roller increases as the load of the conveying wheel increases. When the conveying wheel is unloaded, the torque requirement of the first transmission roller to drive the conveying wheel to rotate is small, and the output power of the motor is small, thereby saving energy and reducing the wear of each transmission member. When the load on the conveying wheel is large, the output torque requirement of the first transmission roller is larger, and the wear between the transmission members is large, and the structure can adaptively adjust the driving power required by the first transmission roller according to the load on the conveying wheel. The connecting bracket is driven forward or backward by the second driving mechanism. Since the connecting bracket is hinged to the side of the balance wheel bracket, the forward movement of the connecting bracket can drive the balance wheel bracket to rotate counterclockwise, and the backward movement can drive the balance wheel bracket to rotate clockwise, and the conveying wheel can rotate synchronously with the rotation of the balance wheel bracket to convey objects in multiple directions. By setting up the clearance space, when the second driving mechanism drives the connecting bracket to move forward and backward, if displacement in the left and right directions occurs, the clearance space can be used to make way regardless of how the driving is performed, so as to ensure the normal operation of the second driving mechanism and prevent the mechanical structure from getting stuck and damaged.

[0008] In the above-mentioned balance wheel sorting machine, a movable gap is provided between the balance wheel bracket and the first support shaft, which allows the conveying wheel to drive the first support shaft to move upward or downward. When the load on the conveying wheel increases, the conveying wheel moves downward and keeps close contact with the first transmission mechanism, and the interaction force between the conveying wheel and the first transmission mechanism increases.

[0009] The movable gap is utilized to allow the conveying wheel to move up and down according to the size of the load it bears. When unloaded, the conveying wheel and the first transmission mechanism are only in a close contact relationship, the interaction force between the two is small, and the torque required for rotation is small. When the load is large, the conveying wheel and the first transmission mechanism are in close contact, the interaction force between the two is large, and the torque required for rotation is also large.

[0010] In the above-mentioned balance wheel sorting machine, as another solution, a movable gap is provided between the balance wheel bracket and the first transmission roller so that the balance wheel bracket can move upward or downward. When the load on the conveying wheel increases, the balance wheel bracket can move along the axial direction of the first transmission roller so that the first transmission mechanism is kept in close contact with the top of the first transmission roller, and the interaction force between the first transmission mechanism and the first transmission roller is increased.

[0011] By setting a movable gap between the balance wheel bracket and the first transmission roller, the increase in load can drive the conveying wheel to sink. Since the balance wheel bracket is movable, the balance wheel bracket sinks synchronously so that the first transmission mechanism and the first transmission roller are in close contact, so the interaction force between the two is increased, and the torque required for rotation is also increased.

[0012] In the above-mentioned pendulum wheel sorting machine, the second driving mechanism includes a second driving motor, and the output shaft of the second driving motor is provided with a rotating member that can drive the connecting bracket to move forward or backward. The force-applying part of the rotating member deviates from the axis of the output shaft of the second driving motor, and the clearance space includes a clearance groove provided on the connecting bracket, and the force-applying part of the rotating member can move leftward or rightward in the clearance groove.

[0013] By setting the force-applying part of the rotating member to be offset from the axis of the output shaft of the second drive motor, when the output shaft of the second drive motor operates normally, the force-applying part can revolve around the output shaft, and when the output shaft of the drive mechanism operates abnormally, the force-applying part can move out of the way through the give-way groove.

[0014] In the above-mentioned balance wheel sorting machine, the force-applying part is located at the top of the rotating member and is rotatable in a ring shape, and the clearance groove is sleeved on the force-applying part, and the clearance groove is a waist-shaped groove.

[0015] The force-applying part can move along the groove by sleeve-arranging the yielding groove on the force-applying part. The two ends of the waist-shaped groove are provided with arc guides to facilitate the movement of the force-applying part.

[0016] In the above-mentioned balance wheel sorting machine, the first transmission mechanism includes a second support shaft arranged on the balance wheel bracket, a first transmission wheel and a second transmission wheel respectively arranged at both ends of the second support shaft, a first coupling part is provided on the top of the first transmission roller, a second coupling part that can be coupled with the first coupling part is provided on the side of the first transmission wheel, and the conveying wheel is respectively coupled with the top of the first transmission wheel and the top of the second transmission wheel.

[0017] The first transmission wheel is connected to the conveying wheel at the top and the first transmission roller at the bottom, and plays the role of transmitting power and load. The second transmission wheel is located at the other end of the second support shaft, and plays the role of assisting in transmitting power and balancing the second support shaft to prevent the second support shaft from tilting and affecting the transmission effect. The first coupling part and the second coupling part can be matching umbrella-shaped, arc-shaped or linear.

[0018] In the above-mentioned pendulum wheel sorting machine, the first driving mechanism includes a first driving motor, a driving wheel is arranged on the output shaft of the first driving motor, a second transmission mechanism is arranged between the first transmission roller and the driving wheel, and the driving wheel can drive the first transmission roller to rotate through the second transmission mechanism. The second transmission mechanism is used to transmit the power of the driving wheel to the first transmission roller.

[0019] In the above-mentioned pendulum wheel sorting machine, the second transmission mechanism includes a second transmission roller arranged between the driving wheel and the first transmission roller, a third transmission wheel arranged on the second transmission roller, and a driven wheel arranged on the second transmission roller, the driven wheel can drive the second transmission roller to rotate, the bottom of the first transmission roller is coupled with the third transmission wheel, and the interaction force between the first transmission roller and the third transmission wheel increases with the increase of the load on the first transmission roller, and the driving wheel is coupled with the driven wheel.

[0020] Since the driving wheel is coupled to the driven wheel, the rotation of the driving wheel can drive the driven wheel to rotate, and the rotation of the driven wheel can drive the second transmission roller and the third transmission wheel to rotate synchronously. Since the first transmission roller and the third transmission wheel are coupled, the force between the two also increases as the load on the conveying wheel increases, and the torque required to drive the third transmission wheel also increases.

[0021] In the above-mentioned pendulum wheel sorting machine, a third coupling part is provided at the bottom of the first transmission roller, and a fourth coupling part which can be coupled with the third coupling part is provided at the side of the third transmission wheel.

[0022] By coupling the bottom of the first transmission roller with the side of the third transmission wheel, the horizontal rotation of the third transmission wheel can be converted into the vertical rotation of the first transmission roller.

DETAILED DESCRIPTION

[0031] 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.

[0032] like Figure 1-4 As shown, the present invention comprises a frame 1, on which a plurality of balance wheel mechanisms 2 are arranged, wherein the balance wheel mechanism 2 comprises a balance wheel bracket 21 rotatably arranged on the frame 1, a first support shaft 22 arranged on the balance wheel bracket 21, and a conveying wheel 23 arranged on the first support shaft 22 and capable of carrying and conveying objects, wherein a first transmission roller 3 is arranged below the conveying wheel 23, wherein a first driving mechanism for driving the first transmission roller 3 to rotate is arranged below the first transmission roller 3, wherein a connecting bracket 4 is hingedly connected to the side of the balance wheel bracket 21, wherein a connecting bracket 4 is arranged below the connecting bracket 4 for driving the first transmission roller 3 to rotate. A second driving mechanism for forward or backward movement, a first transmission mechanism 5 is provided between the conveying wheel 23 and the first transmission roller 3, the first transmission roller 3 can drive the conveying wheel 23 to rotate around the first fixed axis through the first transmission mechanism 5, the conveying wheel 23 and the first transmission roller 3 are coupled by setting the first transmission mechanism 5, and the interaction force between the conveying wheel 23 and the first transmission roller 3 increases with the increase of the load on the conveying wheel 23, and a clearance space for the connecting bracket 4 to move along the left and right direction thereof is provided between the connecting bracket 4 and the second driving mechanism.

[0033] The balance wheel bracket 21 is used to install the first support shaft 22, the first support shaft 22 is used to install the conveying wheel 23, the first driving mechanism is used to drive the first transmission roller 3 to rotate, and the first transmission roller 3 drives the conveying wheel 23 to rotate through the first transmission mechanism 5. Since the conveying wheel 23 and the first transmission roller 3 are coupled through the first transmission mechanism 5, the force between the conveying wheel 23 and the first transmission roller 3 increases as the load of the conveying wheel 23 increases. When the conveying wheel 23 is unloaded, the torque required for the first transmission roller 3 to drive the conveying wheel 23 to rotate is small, and the output power of the motor is small, which saves energy while reducing the wear of each transmission component. When the load on the conveying wheel 23 is large, the output torque requirement of the first transmission roller 3 is larger, and the wear between the transmission components is large. The present structure can adaptively adjust the driving power required by the first transmission roller 3 according to the load on the conveying wheel 23. The connecting bracket 4 is driven to move forward or backward by the second driving mechanism. Since the connecting bracket 4 is hinged to the side of the balance wheel bracket 21, the connecting bracket 4 can drive the balance wheel bracket 21 to rotate counterclockwise when it moves forward, and can drive the balance wheel bracket 21 to rotate clockwise when it moves backward. The conveying wheel 23 can rotate synchronously with the rotation of the balance wheel bracket 21 to convey objects in multiple directions. By setting the yielding space, when the second driving mechanism drives the connecting bracket 4 to move forward and backward, if displacement in the left and right directions occurs, no matter how it is driven, it can yield through the yielding space to ensure the normal operation of the second driving mechanism and prevent the mechanical structure from being stuck and damaged.

[0034] There is a movable gap between the balance wheel bracket 21 and the first support shaft 22, which can be used for the conveying wheel 23 to drive the first support shaft 22 to move upward or downward. When the load on the conveying wheel 23 increases, the conveying wheel 23 moves downward to keep close to the first transmission mechanism 5, and the interaction force between the conveying wheel 23 and the first transmission mechanism 5 increases. The movable gap allows the conveying wheel 23 to move up and down according to the load it bears. When it is unloaded, the conveying wheel 23 and the first transmission mechanism 5 are only in a close relationship, the interaction force between the two is small, and the torque required for rotation is small. When the load is large, the conveying wheel 23 and the first transmission mechanism 5 are in close contact, the interaction force between the two is large, and the torque required for rotation is also large.

[0035] The second driving mechanism includes a second driving motor 6, and a rotating member 7 is provided on the output shaft of the second driving motor 6, which can drive the connecting bracket 4 to move forward or backward. The force-applying portion 71 of the rotating member 7 deviates from the axis of the output shaft of the second driving motor 6. The clearance space includes a clearance groove 8 provided on the connecting bracket 4, and the force-applying portion 71 of the rotating member 7 can move leftward or rightward in the clearance groove 8. By setting the force-applying portion 71 of the rotating member 7 to be offset from the axis of the output shaft of the second driving motor 6, when the output shaft of the second driving motor 6 operates normally, the force-applying portion 71 can revolve around the output shaft, and when the output shaft of the waiting driving mechanism operates abnormally, the force-applying portion 71 can make way through the clearance groove 8.

[0036] The force-applying part 71 is located at the top of the rotating member 7 and is annular and rotatable. The clearance groove 8 is sleeved on the force-applying part 71. The clearance groove 8 is a waist-shaped groove. By sleeved on the force-applying part 71, the force-applying part 71 can move along the groove. The two ends of the waist-shaped groove have arc guides to facilitate the movement of the force-applying part 71.

[0037] The first transmission mechanism 5 comprises a second support shaft 51 arranged on the balance wheel bracket 21, a first transmission wheel 52 and a second transmission wheel 53 respectively arranged at both ends of the second support shaft 51, a first coupling portion 31 is arranged on the top of the first transmission roller 3, a second coupling portion 521 which can be coupled with the first coupling portion 31 is arranged on the side of the first transmission wheel 52, and the conveying wheel 23 is respectively coupled with the top of the first transmission wheel 52 and the top of the second transmission wheel 53. The first transmission wheel 52 is connected to the conveying wheel 23 on the top and the first transmission roller 3 on the bottom, and plays the role of transmitting power and load. The second transmission wheel 53 is located at the other end of the second support shaft 51, and plays the role of assisting in transmitting power and balancing the second support shaft 51, so as to prevent the second support shaft 51 from tilting and thus affecting the transmission effect.

[0038] The first driving mechanism includes a first driving motor 9, a driving wheel 10 is arranged on the output shaft of the first driving motor 9, a second transmission mechanism 11 is arranged between the first transmission roller 3 and the driving wheel 10, and the driving wheel 10 can drive the first transmission roller 3 to rotate through the second transmission mechanism 11. The power of the driving wheel 10 is transmitted to the first transmission roller 3 by the second transmission mechanism 11.

[0039] The second transmission mechanism 11 includes a second transmission roller 111 disposed between the driving wheel 10 and the first transmission roller 3, a third transmission wheel 112 disposed on the second transmission roller 111, and a driven wheel 113 disposed on the second transmission roller 111. The driven wheel 113 can drive the second transmission roller 111 to rotate. The bottom of the first transmission roller 3 is coupled with the third transmission wheel 112, and the interaction force between the first transmission roller 3 and the third transmission wheel 112 increases as the load on the first transmission roller 3 increases. The driving wheel 10 is coupled with the driven wheel 113. Since the driving wheel 10 is coupled with the driven wheel 113, the rotation of the driving wheel 10 can drive the driven wheel 113 to rotate, and the rotation of the driven wheel 113 can drive the second transmission roller 111 and the third transmission wheel 112 to rotate synchronously. Since the first transmission roller 3 is coupled with the third transmission wheel 112, the action force between the two also increases as the load on the conveying wheel 23 increases, and the torque required to drive the third transmission wheel 112 also increases.

[0040] The bottom of the first transmission roller 3 is provided with a third coupling portion 114, and the side of the third transmission wheel 112 is provided with a fourth coupling portion 115 that can be coupled with the third coupling portion 114. By arranging the bottom of the first transmission roller 3 and the side of the third transmission wheel 112 to be coupled, the rotation of the third transmission wheel 112 in the horizontal direction can be converted into the rotation of the first transmission roller 3 in the vertical direction.

[0041] The frame 1 is provided with a support seat 12 for supporting the connecting bracket 4, the connecting bracket 4 is movably connected to the support seat 12, and the support seat 12 is provided with a limiter 121 that can prevent the connecting bracket 4 from being separated from it. By providing the support seat 12 to carry the connecting bracket 4, its height position can also be raised for easy movement, and the limiter 121 is provided to prevent the connecting bracket 4 from being separated to ensure its stability during movement.

[0042] Working principle of the present invention: the driving wheel 10 on the output shaft of the first driving mechanism rotates to drive the driven wheel 113 on the second transmission roller 111 to rotate, and the driven wheel 113 rotates to drive the second transmission roller 111 and the third transmission wheel 112 to rotate synchronously. Since the side of the third transmission wheel 112 is coupled with the bottom of the first transmission roller 3, the third transmission wheel 112 drives the first transmission roller 3 to rotate, and the top of the first transmission roller 3 is coupled with the side of the first transmission wheel 52. The first transmission roller 3 drives the first transmission wheel 52 to rotate, and the rotation of the first transmission wheel 52 drives the second support shaft 51 and the second transmission wheel 53 to rotate synchronously. Since the bottom of the conveying wheel 23 is coupled with the first transmission wheel 52 and the second transmission wheel 53 respectively, the conveying wheel 23 is driven to rotate. When the conveying wheel 23 is unloaded, the acting force between the transmission parts is small, and the first driving motor 9 The driving power is also small. When there is an object on the conveying wheel 23, the acting force between the transmission parts is large, and the driving power of the first driving motor 9 is also large. The system can also divide the objects into three categories, such as small weight objects, heavy weight objects, and large weight objects, corresponding to the execution of the conveying wheel 23 in the same direction or turning left or right, that is, the second driving motor 6 drives the rotating member 7 to rotate, and the force applying part 71 on the rotating member 7 drives the connecting bracket 4 to move forward or backward. Since the connecting bracket 4 is hinged to the side of the balance wheel bracket 21, the forward movement of the connecting bracket 4 can drive the balance wheel bracket 21 to rotate in the counterclockwise direction, and the backward movement of the connecting bracket 4 can drive the balance wheel bracket 21 to rotate in the clockwise direction. When the second driving mechanism encounters an electrical failure, the force applying part 71 above the rotating member 7 can move by means of the clearance groove 8 to avoid jamming and damage.

[0043] The present invention utilizes the first transmission mechanism 5 to couple with the conveying wheel 23 and the first transmission roller 3 respectively, so that the first driving mechanism can adaptively adjust the driving power required for the first transmission roller 3 according to the load size on the conveying wheel 23; by setting a clearance space, when the second driving mechanism drives the connecting bracket 4 to move forward and backward, if displacement in the left and right directions occurs, no matter how it is driven, it can make way through the clearance space to ensure the normal operation of the second driving mechanism and prevent the mechanical structure from being stuck and damaged; by setting the first transmission wheel 52 to connect the conveying wheel 23 on the upper side and the first transmission roller 3 on the lower side, it can play the role of transmitting power and load, and setting the second transmission wheel 53 to transmit power and balance the second support shaft 51 to prevent the second support shaft 51 from being skewed and affecting the transmission effect; by setting the second transmission mechanism 11, the power of the driving wheel 10 is transmitted to the first transmission roller 3.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
