Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation, and in particular to a sorting system. Background Technology

[0002] For the express delivery industry, sorting packages is an essential step. Existing sorting methods often use pushers to move packages from one transport line to another. This type of pusher-based sorting device is prone to damaging packages, and for thinner items like clothing, the pusher may miss some. Another existing technology involves embedding the sorting system within the transport components to achieve the sorting action. This embedded sorting system typically uses a longer drive belt that undergoes multiple bends. In cold environments, the drive belt can harden, and an excessively long belt can make it difficult for the drive mechanism to operate. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a sorting system that can drive the transmission belt even in low-temperature and cold environments.

[0004] To this end, one embodiment provides a sorting system including a transport assembly and a frame. The transport assembly is used to move items to be sorted along a first direction. The transport assembly includes a first drive member, a first transmission belt, a second transmission belt, a plurality of first rollers, and a plurality of second rollers. The first drive member is disposed on the frame. The first rollers and the second rollers are rotatably disposed on the frame. The plurality of first rollers are arranged in parallel with their axes on the transport surface. The plurality of second rollers are arranged in parallel with their axes not coplanar with the transport surface. The first transmission belt surrounds the first rollers and the second rollers to link the first rollers and the second rollers. The second transmission belt surrounds the first drive member and at least two of the second rollers.

[0005] As a further alternative to the sorting system, a sorting component is also included, which is spaced apart in the transport component and is capable of moving the item to be sorted along a second direction. The sorting component is also capable of lifting and lowering so that it can be above or below the transport surface.

[0006] As a further alternative to the sorting system, the sorting component includes a lifting mechanism and a transport mechanism. The lifting mechanism is used to support the transport mechanism and control the lifting of the supporting mechanism. The transport mechanism is used to move the items to be sorted along a second direction.

[0007] As a further alternative to the sorting system, the lifting mechanism includes a cam that abuts against the transport mechanism, and the cam drives the transport mechanism to lift when it rotates.

[0008] As a further alternative to the sorting system, the lifting mechanism includes a first cam and a second cam, which are arranged parallel to each other along a second direction. The transport mechanism includes a sorting belt, which is wrapped around the outer peripheral surfaces of the first cam and the second cam to enable the first cam and the second cam to move together.

[0009] As a further alternative to the sorting system, the circumferential surfaces of the first cam and the second cam include arc segments and planar segments.

[0010] As a further alternative to the sorting system, the sorting assembly further includes a first rotating shaft, which is fixedly disposed at the center of a plurality of the first cams.

[0011] As a further alternative to the sorting system, the sorting component includes a second drive member for driving the first rotating shaft to rotate.

[0012] As a further alternative to the sorting system, the frame is provided with a strip-shaped hole, and at least one second roller can move along the length direction of the strip-shaped hole and be fixed.

[0013] As a further alternative to the sorting system, a control component is also included, which is mounted on the frame.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects:

[0015] According to the sorting system in the above embodiments, the transport component can move the items to be sorted along a first direction, and multiple first rollers form a transport surface, i.e., a transport plane. Multiple second rollers are not coplanar with the transport surface, thus allowing gaps between the first rollers. These gaps can be used to place the sorting component; since the sorting component is lifted, even very thin items to be sorted will not be missed. A first drive belt enables linkage between the first and second rollers. Because the second drive belt can link the first driving member and at least two second rollers, the transmission capacity of the first driving member on the drive belt is greatly improved. The first drive belt is driven by two second rollers, so it can overcome greater resistance and can still function normally even if the first drive belt hardens due to low temperature. Implementing the sorting system of this invention enables the drive belt to be driven even in low-temperature environments. Attached Figure Description

Detailed Implementation

[0026] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] This utility model provides a sorting system, please refer to... Figures 1-4 The sorting system includes a transport assembly (not shown) and a frame 20. The transport assembly is used to move the items to be sorted along a first direction. The transport assembly includes a first drive member 110, a first transmission belt 120, a second transmission belt (not shown), a plurality of first rollers 140 and a plurality of second rollers 150. The first drive member 110 is disposed on the frame 20. The first rollers 140 and the second rollers 150 are both rotatably disposed on the frame 20. The plurality of first rollers 140 are arranged in parallel and their axes are located on the transport surface. The plurality of second rollers 150 are arranged in parallel and their axes are not coplanar with the transport surface. The first transmission belt 120 surrounds the first rollers 140 and the second rollers 150 to link the first rollers 140 and the second rollers 150. The second transmission belt surrounds the first drive member 110 and at least two second rollers 150.

[0030] According to the sorting system in the above embodiments, the transport component can move the items to be sorted along a first direction. Multiple first rollers 140 form a transport surface, i.e., a transport plane. Multiple second rollers 150 are not coplanar with the transport surface, thus allowing gaps between the first rollers 140. These gaps can be used to place the sorting component 30. Since the sorting component 30 is lifted, even very thin items to be sorted will not be missed. A first drive belt 120 enables linkage between the first rollers 140 and the second rollers 150. Because the second drive belt can link the first drive member 110 and at least two second rollers 150, the transmission capacity of the first drive member 110 to the drive belt is greatly improved. The first drive belt 120 is driven by two second rollers 150, so it can overcome greater resistance and can still function normally even if the first drive belt 120 hardens due to low temperature. Implementing the sorting system of this invention enables the drive belt to be driven even in low-temperature environments.

[0031] It should be noted that, please refer to Figure 1 Let X be the first direction and Y be the second direction. The first direction is the direction in which the items to be sorted are transported, and the second direction is a direction that is not parallel to the first direction; the second direction is generally perpendicular to the first direction. The transport surface is the direction in which the items to be sorted are transported. In this utility model, the preferred technical solution is that the transport surface and the second plane are arranged parallel to each other.

[0032] Please refer to Figure 3 , Figure 3 The two second rollers 150 marked in the middle are linked to the first drive component 110 via a second transmission belt, which is roughly triangular in structure. This arrangement provides the transport assembly with two power sources, overcoming the stiffness of the first transmission belt 120 caused by low temperature.

[0033] In some specific embodiments, a sorting component 30 is also included. The sorting component 30 is spaced apart in the transport component and is capable of moving the items to be sorted along a second direction. The sorting component 30 is capable of being raised or lowered so that it can be above or below the transport surface.

[0034] Specifically, sorting components 30 are spaced apart between the first rollers 140. Two adjacent first rollers 140 form a transport surface, and each group of rollers is linked by a second roller 150 and a first drive belt 120. A sorting component 30 is positioned between each group of rollers. When the sorting component 30 is above the transport surface, it can lift the item to be sorted, thus allowing the item to move in a second direction. When the sorting component 30 is below the surface, it will not affect the item to be sorted.

[0035] Furthermore, a third drive belt 130 can be provided for the two first rollers 140 that form a group to facilitate better transport of the items to be sorted.

[0036] In some specific embodiments, the sorting assembly 30 includes a lifting mechanism (not shown) and a transport mechanism (not shown), the lifting mechanism being used to support the transport mechanism and control the lifting of the support mechanism, and the transport mechanism being used to move the items to be sorted along a second direction.

[0037] In this embodiment, a lifting mechanism and a transport mechanism are included. The lifting mechanism is responsible for raising or lowering the transport mechanism. When the transport mechanism is raised and separates the items to be sorted from the transport component, the transport mechanism starts to move and move the items to be sorted along the second direction.

[0038] The transport mechanism can be a conveyor belt or roller assembly along the second direction, and the lifting mechanism can be a cylinder lifting mechanism, a screw lifting mechanism, or a crank mechanism, etc.

[0039] In some specific embodiments, the lifting mechanism includes a cam 3110, which abuts against the transport mechanism. When the cam 3110 rotates, it drives the transport mechanism to lift.

[0040] In this embodiment, the lifting and lowering of the conveyor mechanism is mainly achieved by the rotation of cam 3110. Cam 3110 lifting and lowering has advantages such as fast response speed and simple structure. Using cam 3110 can improve sorting efficiency and reduce the failure rate of the sorting system.

[0041] Generally, sorting belts 3210 are relatively narrow, and multiple sorting belts 3210 need to cooperate with each other to achieve better sorting. Therefore, the first rotating shaft 330 can ensure the synchronicity of the rotation of the first cam 3111. As for the second cam 3112, due to the linkage of the sorting belts 3210, it generally rotates along with the rotation of the first cam 3111.

[0042] In this embodiment, the lifting mechanism includes a first cam 3111 and a second cam 3112, which are arranged parallel to each other along a second direction. The transport mechanism includes a sorting belt 3210, which is wrapped around the outer peripheral surfaces of the first cam 3111 and the second cam 3112 to make the first cam 3111 and the second cam 3112 move together.

[0043] In this embodiment, the lifting motion and the transport motion of the transport mechanism are linked together by winding the sorting belt 3210 around the first cam 3111 and the second cam 3112 respectively. When the first cam 3111 and the second cam 3112 rotate, not only can the items to be sorted be lifted, but the sorting belt 3210 also moves the items to be sorted along the second direction, thereby completing the sorting work.

[0044] In this embodiment, the sorting operation can be achieved simply by driving the first cam 3111 or the second cam 3112, which simultaneously realizes the lifting and moving actions of the transport mechanism.

[0045] In some specific embodiments, please refer to Figure 6 The circumferential surfaces of the first cam 3111 and the second cam 3112 include an arc segment 3110a and a planar segment 3110b.

[0046] The arc segment 3110a can lift the sorting belt 3210, and the flat segment 3110b can lower the sorting belt 3210. When the first cam 3111 or the second cam 3112 rotates one revolution, it is exactly equal to the sum of the distances of the arc segment 3110a and the flat segment 3110b that the sorting belt 3210 has rotated.

[0047] Generally, the width of the transport component should be less than the sum of the arc segment 3110a and the flat segment 3110b, so that the items to be sorted can be sorted within one revolution of the first cam 3111 or the second cam 3112. Furthermore, the flat segment 3110b and the arc segment 3110a are connected end to end, which makes the lifting and lowering of the sorting belt 3210 or its movement in the second direction very smooth.

[0048] In some specific embodiments, the sorting assembly 30 further includes a first rotating shaft 330, which is fixedly disposed at the center of a plurality of first cams 3111.

[0049] Generally, sorting belts 3210 are relatively narrow, and multiple sorting belts 3210 need to cooperate with each other to achieve better sorting. Therefore, the first rotating shaft 330 can ensure the synchronicity of the rotation of the first cam 3111. As for the second cam 3112, due to the linkage of the sorting belts 3210, it generally rotates along with the rotation of the first cam 3111.

[0050] In some specific embodiments, the sorting assembly 30 includes a second drive 340 for driving the first rotating shaft 330 to rotate.

[0051] The second driving component 340 is usually a motor, which is generally connected to the first rotating shaft 330 through gear meshing.

[0052] In some specific embodiments, please refer to Figure 1 and Figure 5 The frame 20 is provided with a strip hole 210, and at least one second roller 150 can move along the length direction of the strip hole 210 and be fixed.

[0053] The length direction of the strip hole 210 is generally parallel to the second plane. By adjusting the position of the second roller 150 on the strip hole 210, the tension of the first transmission belt 120 can be adjusted.

[0054] In some specific embodiments, a control component 40 is also included, which is disposed on the rack 20.

[0055] The control assembly includes a control unit for controlling the first drive element 110 and the second drive element 340, and generally also has a communication unit. The communication unit receives external signals and controls the operation of the first drive element 110 and the second drive element 340 according to the signals.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
