Description

Technical Field

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

[0002] At present, compared with belt conveyor belts, modular conveyor belts are not easy to snake or deflect, and are resistant to cutting, collision, oil and water. They can be widely used in assembly lines, automated production, logistics transmission and other fields. They are necessary equipment for conveying items in various fields.

[0003] When the goods on the modular conveyor belt need to enter the corresponding position for turning after identification, the jacking mechanism can drive the pendulum mechanism at the corresponding position to rise, so that the top of the pendulum mechanism contacts the bottom of the conveying wheel, so that the conveying wheel on the main conveyor belt is subjected to the friction component parallel to the direction of the rotating shaft, thereby realizing rotation around itself, and the goods move along the conveying direction perpendicular to the main conveyor belt to the side or enter the sorting conveyor belt to complete the sorting action.

[0004] Since the balance wheel in the prior art is a relatively long single-wheeled type, it is always in contact with the module mounting plate and the conveying wheel regardless of whether it is in the sorting state or the non-sorting state, resulting in a loud operating noise and easy wear and tear during long-term operation, thereby reducing the service life of the equipment. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide a sorting device that can reduce wear.

[0006] The objective of the present invention can be achieved through the following technical scheme: a sorting device, comprising a frame, the frame is provided with a plurality of swingable swing modules, a driving device that can drive the swing modules to swing in the horizontal direction is provided below the swing modules, a conveyor belt for conveying objects is provided on the swing modules, a plurality of conveying wheels that can be driven and rotated by the swing modules are hinged on the conveyor belt, a partition is provided between the conveying wheels, a clearance space is formed between the conveying wheels and the partition, the swing module comprises two rotatable driving wheels, when the driving wheel swings until its axis is perpendicular to the axis of the conveying wheel, the driving wheel can abut against the partition and be embedded in the clearance space, and the conveying wheel does not rotate, and when the driving wheel swings to the left or right, it can abut against the conveying wheel and drive the conveying wheel to rotate clockwise or counterclockwise for sorting.

[0007] The conveying wheel can rotate clockwise or counterclockwise to sort and convey objects to both sides of the conveyor belt. The driving device drives the swing module to swing in the horizontal direction. The driving wheel on the swing module can drive the conveying wheel to rotate. Since the driving wheel can swing synchronously with the swing module, when the equipment is in a non-sorting state, the driving wheel can be swung to the clearance space between the two conveying wheels to abut against the partition, not against the conveying wheel, thereby reducing friction noise and additional wear, effectively increasing the service life of the conveyor belt, and reducing the maintenance cost of the equipment. When the equipment needs to be switched to a sorting state, the horizontal position of the driving wheel can be adjusted to abut against the conveying wheel, and the conveying wheel can be controlled to rotate clockwise or counterclockwise according to the swing angle to achieve sorting.

[0008] In the above-mentioned sorting equipment, the swing module also includes a swing bracket hinged on the frame and driven by a driving device to swing horizontally. Two driving wheels are hinged on the swing bracket, and a gap is provided between the driving wheels.

[0009] The swing bracket is used to install the driving wheel. Setting a gap can avoid interference between the two driving wheels. One swing bracket is used in conjunction with two smaller driving wheels to drive the two conveying wheels to rotate respectively. Compared with the prior art, one driving unit can only drive one conveying wheel to rotate, which improves efficiency and reduces manufacturing costs.

[0010] In the above-mentioned sorting equipment, the two driving wheels on the swing bracket are symmetrically arranged with the swing bracket hinge axis as the center. After swinging, the driving wheels can respectively abut against the adjacent conveying wheels or be embedded in the clearance space together to abut against the partition.

[0011] By arranging two driving wheels with the hinge axis of the swing bracket as the center, after the swing bracket is deflected, the two driving wheels can support the two conveying wheels in two directions respectively, with strong supporting reliability, or the two driving wheels are simultaneously embedded in the clearance space and offset against the partition, and the conveying wheel does not rotate at this time.

[0012] In the above-mentioned sorting equipment, the conveyor belt includes a plurality of connecting plates for mounting conveying wheels, and the connecting plates are hinged.

[0013] By arranging the connection plates to be hinged, some of the connection plates can be rotated at a certain angle after being lifted.

[0014] In the above-mentioned sorting equipment, a connecting piece which can drive the swing module to swing in the horizontal direction is provided at the bottom of the swing module through the frame, and the driving device includes a driving mechanism which is arranged on the frame and can drive the connecting piece to swing in the horizontal direction, and the connecting piece and the driving mechanism are transmitted through a transmission mechanism.

[0015] The driving mechanism drives the connecting member to swing horizontally through the transmission mechanism, and the horizontal swing of the connecting member drives the swing module to swing horizontally.

[0016] In the above-mentioned sorting equipment, the driving mechanism includes a driving motor arranged at the bottom of the frame, a driving arm arranged on the output shaft of the driving motor, and a rotating wheel hinged on the driving arm. The axis of the rotating wheel is far away from the axis of the output shaft of the driving motor, and the rotating wheel can drive the transmission mechanism to swing.

[0017] The output shaft of the driving motor rotates to drive the driving arm to rotate. Since the axis of the rotating wheel is axially away from the axis of the output shaft of the driving mechanism, the rotation of the driving arm can drive the rotating wheel to rotate or deflect around the output shaft. The deflection of the rotating wheel can drive the transmission mechanism to swing.

[0018] In the above-mentioned sorting device, as another solution, the driving mechanism includes a cylinder, an electric cylinder or a hydraulic cylinder arranged at the bottom of the frame. The cylinder, the electric cylinder or the hydraulic cylinder can also be used to drive the connecting member to swing through the transmission mechanism.

[0019] In the above-mentioned sorting equipment, the transmission mechanism includes a swinging member arranged on the driving mechanism and driven by the driving mechanism to swing, and a plurality of connecting rods arranged on the swinging member, each of the connecting rods is hinged to a plurality of connecting members, and the swinging member is provided with an active groove into which the output end of the driving mechanism can extend.

[0020] After the output end of the driving mechanism extends into the movable groove, it can drive the swinging part to swing. By setting a connecting rod to connect multiple connecting parts, and by connecting the connecting rod to the swinging part, the driving mechanism only needs to drive the swinging part to drive multiple connecting parts to swing.

[0021] In the above-mentioned sorting device, the movable groove is waist-shaped. By providing the waist-shaped movable groove, the balance wheel module can be adjusted at multiple angles.

[0022] In the above-mentioned sorting equipment, the swing modules are divided into a plurality of swing module arrays, and each swing array has a driving device under it to drive the swing.

[0023] By arranging a plurality of swing arrays and matching them with a driving device, the conveyor belt can perform multi-group sorting at the same time.

[0024] Compared with the prior art, in the non-sorting state, the present invention reduces friction noise and additional wear by swinging the driving wheel into the clearance space between the two conveying wheels to abut against the partition instead of against the conveying wheel, thereby effectively increasing the service life of the conveyor belt and reducing the maintenance cost of the equipment. When the equipment needs to be switched to the sorting state, the driving wheel is controlled to swing leftward or rightward to abut against the conveying wheel, and the conveying wheel is controlled to rotate clockwise or counterclockwise according to the actual swing angle to achieve sorting; a swing bracket is used in combination with two smaller driving wheels to respectively drive the two conveying wheels to rotate, that is, only one driving unit is used to drive the two conveying wheels to rotate at the same time, which not only improves efficiency but also saves a lot of material costs; by setting up multiple swing arrays and matching them with a driving device, the conveyor belt can perform multi-group sorting at the same time, thereby improving sorting efficiency.

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 1-5As shown, the present invention includes a frame 1, on which a plurality of swingable swing modules 2 are provided, below which a driving device 3 which can drive the swing modules 2 to swing in a horizontal direction is provided, on which a conveyor belt 4 for conveying objects is provided, on which a plurality of conveying wheels 5 which can be driven and rotated by the swing modules 2 are hinged, a partition 42 is provided between the conveying wheels 5, a clearance space is formed between the conveying wheels 5 and the partition 42, and the swing module 2 includes two rotatable driving wheels 21, when the driving wheel 21 swings until its axis is perpendicular to the axis of the conveying wheel 5, the driving wheel 21 can abut against the partition 42 and be embedded in the clearance space, and the conveying wheel 5 does not rotate, and when the driving wheel 21 swings to the left or right, it can abut against the conveying wheel 5 and drive the conveying wheel 5 to rotate clockwise or counterclockwise for sorting.

[0033] The conveying wheel 5 can rotate clockwise or counterclockwise to sort and convey objects to both sides of the conveyor belt 4. The driving device 3 drives the swing module 2 to swing in the horizontal direction. The driving wheel 21 on the swing module 2 can drive the conveying wheel 5 to rotate. Since the driving wheel 21 can swing synchronously with the swing module 2, when the equipment is in a non-sorting state, the driving wheel 21 can be swung to the clearance space between the two conveying wheels 5 to abut against the partition 42, and not against the conveying wheel 5, thereby reducing friction noise and additional wear, effectively increasing the service life of the conveyor belt 4, and reducing the maintenance cost of the equipment. When the equipment needs to be converted to a sorting state, the horizontal position of the driving wheel 21 can be adjusted to abut against the conveying wheel 5, and the conveying wheel 5 can be controlled to rotate clockwise or counterclockwise according to the swing angle to achieve sorting.

[0034] The swing bracket 22 is used to install the driving wheel 21. The gap is set to avoid interference between the two driving wheels 21. One swing bracket 22 is used in conjunction with two smaller driving wheels 21 to respectively drive the two conveying wheels 5 to rotate. Compared with the prior art, one driving unit can only drive one conveying wheel 5 to rotate, which improves efficiency and reduces manufacturing costs.

[0035] The two driving wheels 21 on the swing bracket 22 are symmetrically arranged with the hinge axis of the swing bracket 22 as the center. After swinging, the driving wheels 21 can respectively abut against the adjacent conveying wheels 5 or be embedded in the clearance space together to abut against the partition 42.

[0036] By arranging two driving wheels 21 with the hinge axis of the swing bracket 22 as the center, after the swing bracket 22 is deflected, the two driving wheels 21 can support the two conveying wheels 5 in two directions respectively, and the supporting reliability is strong, or the two driving wheels 21 are simultaneously embedded in the clearance space and abut against the partition 42, and the conveying wheel 5 does not rotate, and no sorting is performed at this time.

[0037] The conveyor belt 4 includes a plurality of connecting plates 41 for mounting the conveyor wheel 5, and the connecting plates 41 are hinged. By arranging the connecting plates 41 to be hinged, it is convenient for some connecting plates 41 to rotate at a certain angle after being lifted.

[0038] The bottom of the swing module 2 passes through the frame 1 and is provided with a connecting member 6 that can drive it to swing in the horizontal direction. The driving device 3 includes a driving mechanism 31 that is arranged on the frame 1 and can drive the connecting member 6 to swing in the horizontal direction. The connecting member 6 and the driving mechanism 31 are driven by a transmission mechanism 32. The driving mechanism 31 drives the connecting member 6 to swing horizontally through the transmission mechanism 32, and the horizontal swing of the connecting member 6 drives the swing module 2 to swing horizontally.

[0039] The driving mechanism 31 includes a driving motor 311 disposed at the bottom of the frame 1, a driving arm 312 disposed on the output shaft of the driving motor 311, and a rotating wheel 313 hinged on the driving arm 312. The axis of the rotating wheel 313 is far away from the axis of the output shaft of the driving motor 311, and the rotating wheel 313 can drive the transmission mechanism 32 to swing. The output shaft of the driving motor 311 rotates to drive the driving arm 312 to rotate. Since the axis of the rotating wheel 313 is axially far away from the axis of the output shaft of the driving mechanism 31, the rotation of the driving arm 312 can drive the rotating wheel 313 to rotate or deflect with the output shaft as the axis, and the deflection of the rotating wheel 313 can drive the transmission mechanism 32 to swing.

[0040] The transmission mechanism 32 includes a swinging member 321 arranged on the driving mechanism 31 and driven to swing, and a plurality of connecting rods 322 arranged on the swinging member 321. Each of the connecting rods 322 is hinged with a plurality of connecting members 6. The swinging member 321 is provided with an active groove 323 for the output end of the driving mechanism 31 to extend into. After the output end of the driving mechanism 31 extends into the active groove 323, the swinging member 321 can be driven to swing. By setting the connecting rod 322 to connect the plurality of connecting members 6, and by connecting the connecting rod 322 to the swinging member 321, the driving mechanism 31 only needs to drive the swinging member 321 to drive the plurality of connecting members 6 to swing. The active groove 323 is waist-shaped. By setting the waist-shaped active groove 323, the balance wheel module can be adjusted at multiple angles.

[0041] The swing module 2 is divided into multiple swing arrays, and each swing array has a driving device 3 below to drive the swing. By setting multiple swing arrays and supporting the driving device 3, the conveyor belt 4 can perform multiple group sorting at the same time.

[0042] Working principle of the present invention: During specific implementation, the conveyor belt 4 is driven by an additional motor to transport horizontally along the frame 1. The output shaft of the driving motor 311 below the frame 1 rotates to drive the driving arm 312 to rotate. The driving arm 312 rotates to drive the rotating wheel 313 to rotate in the movable groove 323 of the swinging member 321. Due to the restriction of the movable groove 323, the swing of the rotating wheel 313 drives the swinging member 321 to swing together. The swinging of the swinging member 321 drives the connecting rod 322 to swing. The swinging of the connecting rod 322 drives multiple connecting members 6 to swing. The swinging of the connecting member 6 drives the swinging bracket 22 to swing. The swinging of the swinging bracket 22 drives the driving wheel 21 to swing. When the driving wheel 21 swings to the left or right, it can resist the conveying wheel 5 and drive it to rotate clockwise or counterclockwise. The conveying wheel 5 rotates clockwise or counterclockwise to convey objects to both sides of the conveyor belt to achieve sorting. When the driving wheel 21 swings to the clearance space, it can resist the partition 42 between the two conveying wheels 5, and the conveying wheel 5 continues to move forward with the conveyor belt 4 but does not rotate.

[0043] In the non-sorting state, the present invention swings the driving wheel 21 to the clearance space between the two conveying wheels 5 to abut against the partition 42 instead of against the conveying wheel 5, thereby reducing friction noise and additional wear, effectively increasing the service life of the conveyor belt 4, and reducing the maintenance cost of the equipment. When the equipment needs to be switched to the sorting state, the driving wheel 21 is controlled to swing leftward or rightward to abut against the conveying wheel 5, and the conveying wheel 5 is controlled to rotate clockwise or counterclockwise according to the actual swing angle to achieve sorting; a swing bracket 22 is used in combination with two smaller driving wheels 21 to respectively drive the two conveying wheels 5 to rotate, that is, only one driving unit is used to drive the two conveying wheels 5 to rotate at the same time, which not only improves efficiency but also saves a lot of material costs; by setting up multiple swing arrays and matching them with the driving device 3, the conveyor belt 4 can perform multi-group sorting at the same time, thereby improving the sorting efficiency.

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.
