[0002] The existing reciprocating sorting machine includes a frame, a sorting trolley supported by the frame and reciprocatingly moving, and a driving mechanism for driving the sorting trolley to reciprocate. The sorting trolley receives an article and then reciprocates to send the article into a target sorting bin. In order to ensure the stable and smooth movement of the sorting trolley, a guiding mechanism is usually provided in the reciprocating sorting machine. In the prior art, some guiding mechanisms of the reciprocating sorting machine use rail modules, and some use two groups of U-shaped linear rails arranged in parallel at intervals. However, when using rail modules, there is a problem of high cost. When using U-shaped linear rails, since the sorting trolley needs to be provided with two groups of rollers corresponding to the two groups of U-shaped linear rails one by one, and in order to ensure that the rollers can move smoothly along the U-shaped rails, high-precision matching between the rollers and the U-shaped rails is required, so there are problems of large processing and assembly difficulties.

Detailed implementation manners

[0029] To make the technical problems solved by the present utility model, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0030] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above the", and "on the" second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the", and "under the" second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0032] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0033] Such as Figures 1 to 7As shown in the figure, this embodiment provides a reciprocating sorting machine 10, which includes a frame 1, a sorting trolley 2, a guiding mechanism 3 and a driving mechanism 4. Among them, both ends of the sorting trolley 2 in the first direction (the ab direction in the figure) are supported by the frame 1. The sorting trolley 2 includes a base 21 and a conveying component 22. The conveying component 22 is used to convey articles in the first direction. The guiding mechanism 3 includes a guide rail 31 and two roller assemblies 32. Both ends of the guide rail 31 are supported by the frame 1. The guide rail 31 extends in the second direction (the cd direction in the figure). The two roller assemblies 32 are installed at intervals along the second direction at the bottom of the base 21. Each roller assembly 32 includes two rollers 321. The two rollers 321 are respectively in rolling cooperation with both sides of the guide rail 31 in the first direction. The driving mechanism 4 is in transmission connection with the sorting trolley 2 and is used to drive the sorting trolley 2 to reciprocate in the second direction. Among them, the first direction and the second direction are arranged at an angle. The reciprocating sorting machine 10 provided by this embodiment enables the two rollers 321 of each roller assembly 32 to be in rolling cooperation with both sides of the guide rail 31 to limit the moving direction of the sorting trolley 2, without the need to set two groups of U-shaped linear guide rails arranged in parallel at intervals, making the structure of the reciprocating sorting machine 10 simple, with low cost and easy to process and produce.

[0034] In this embodiment, as Figure 1 and Figure 2 shown, the frame 1 includes four columns 11 and four crossbeams 12. The four crossbeams 12 are arranged in a rectangle. The four columns 11 are distributed at the four vertices of the rectangle. Each column 11 is arranged in the vertical direction. The four crossbeams 12 are respectively connected between two adjacent columns 11. The four crossbeams 12 are respectively two first crossbeams extending in the first direction and two second crossbeams extending in the second direction. Both ends of the guide rail 31 are supported by the two first crossbeams respectively. Both ends of the sorting trolley 2 are supported by the two second crossbeams respectively. The above settings make the structure of the frame 1 simple and strong enough to support the sorting trolley 2. Optionally, a foot 14 supported on the ground is fixed at the bottom of each column 11. Optionally, both the crossbeam 12 and the column 11 are formed by square pipes. Specifically, the guide rail 31 is arranged in parallel and at intervals with the two second crossbeams. Optionally, the distances between the guide rail 31 and the two second crossbeams are equal, so that the middle part of the sorting trolley 2 in the first direction moves along the guide rail 31, thereby guiding the movement of the sorting trolley 2 more smoothly.

[0035] Optionally, in this embodiment, as Figure 1 shown, the frame 1 further includes two support members 13 arranged at intervals in the first direction. Each support member 13 extends in the second direction. The two support members 13 are respectively used to support both ends of the sorting trolley 2 in the first direction.

[0036] Optionally, in this embodiment, as Figure 2As shown, the driving mechanism 4 includes a motor 41, a transmission belt 43, and two belt pulleys 42. The two belt pulleys 42 are respectively supported by the frame 1, and one of the two belt pulleys 42 is in transmission connection with the motor 41. The transmission belt 43 is sleeved on the two belt pulleys 42, and the base 21 is fixedly connected to the transmission belt 43. The motor 41 drives the belt pulley 42 to rotate, drives the transmission belt 43 to move, the transmission belt 43 drives the sorting trolley 2 to move, and at the same time, the guiding mechanism 3 guides the moving direction of the sorting trolley 2 to make the reciprocating movement of the sorting trolley 2 stable.

[0037] Optionally, in this embodiment, as Figure 2 and Figure 3 shown, the guiding mechanism 3 further includes two limit members 33. The two limit members 33 are respectively arranged at both ends of the guide rail 31 along the second direction. The two limit members 33 are arranged in one-to-one correspondence with the two roller assemblies 32, and each limit member 33 is used to abut against the roller 321 of the corresponding roller assembly 32 to limit the two extreme positions of the sorting trolley 2 when moving along the second direction. Specifically, the two limit members 33 are a first limit member and a second limit member arranged along the second direction, the two roller assemblies 32 are a first roller assembly and a second roller assembly arranged along the second direction, the first roller assembly corresponds to the first limit member, and the second roller assembly corresponds to the second limit member. When the roller 321 of the first roller assembly abuts against the first limit member, the sorting trolley 2 is located at the first extreme position. When the roller 321 of the second roller assembly abuts against the second limit member, the sorting trolley 2 is located at the second extreme position. By arranging the two limit members 33 to cooperate with the roller 321 of the corresponding roller assembly 32 to limit the two extreme positions of the sorting trolley 2 along the second direction, it is avoided that other structures of the sorting trolley 2 collide with other structures on the frame 1 when the sorting trolley 2 moves to the extreme position. In addition, by making the roller 321 of the roller assembly 32 rollingly abut against the corresponding limit member 33, the collision force between the roller 321 and the corresponding limit member 33 is effectively relieved, and the protection of the roller 321 and the limit member 33 is improved.

[0038] In this embodiment, as Figure 4As shown, the guide rail 31 is a square tube. The limiting member 33 includes a first plate 331 and a second plate 332 connected at an angle. The first plate 331 is fixedly connected to the square tube. A slot 301 is provided in the middle of the second plate 332, and the square tube passes through the slot 301. The two rollers 321 of each roller assembly 32 are respectively in rolling cooperation with the two opposite tube walls of the square tube, and the two rollers 321 of each roller assembly 32 can simultaneously abut against the second plate 332 on both sides of the slot 301 of the corresponding limiting member 33. The above setting realizes the reliable fixation of the limiting member 33 on the guide rail 31. Optionally, in this embodiment, the square tube includes two first tube walls 311 and two second tube walls 312. The two first tube walls 311 are spaced apart relative to each other in the first direction. The two second tube walls 312 are connected between the two first tube walls 311, and the two second tube walls 312 are spaced apart relative to each other in the third direction (the ef direction in the figure). Among them, the first direction, the second direction, and the third direction are perpendicular to each other in pairs. The two rollers 321 in each roller assembly 32 are respectively in rolling cooperation with the two first tube walls 311. Optionally, the limiting member 33 further includes a bolt 333 and a nut 334. The bolt 333 passes through the first plate 331 and the two second tube walls 312 of the square tube and is threadedly connected to the nut 334, thereby realizing the detachable connection between the limiting member 33 and the square tube. Optionally, in this embodiment, the limiting member 33 further includes a third plate 335. The third plate 335 is connected at an angle to the first end of the first plate 331 away from the second plate 332, and the third plate 335 is opposite to the second plate 332. Such a setting can strengthen the strength of the limiting member 33 and prevent the limiting member 33 from deforming when the roller 321 hits the limiting member 33. Further, the limiting member 33 further includes a fourth plate 336 and a fifth plate 337. The fourth plate 336 and the fifth plate 337 are respectively connected to the two opposite edges of the slot 301 on the second plate 332 and extend towards the third plate 335. The distance between the fourth plate 336 and the fifth plate 337 matches the distance between the two first tube walls 311. The above setting can further strengthen the strength of the limiting member 33 and prevent the limiting member 33 from deforming.

[0039] In this embodiment, as Figure 5 and Figure 6As shown, the sorting trolley 2 further includes two guard plates 23. The two guard plates 23 are respectively located on both sides of the conveying assembly 22 along the second direction, and each guard plate 23 is fixedly connected to the base 21. The two guard plates 23 are both higher than the conveying surface of the conveying assembly 22, and are used to prevent the items on the conveying surface from accidentally falling. Optionally, the conveying assembly 22 includes an electric roller 221, a driven roller 222 and a conveyor belt 223. Among them, the electric roller 221 and the driven roller 222 are arranged at intervals along the first direction. The conveyor belt 223 is sleeved on the electric roller 221 and the driven roller 222. The upper surface of the conveyor belt 223 forms a conveying surface. The items fall on the conveying surface. The electric roller 221 rotates to drive the conveyor belt 223 to move, so that the items located on the conveying surface move, thereby conveying the items along the first direction.

[0040] Optionally, in this embodiment, as Figure 5 and Figure 6 shown, the sorting trolley 2 further includes a driver 24. The base 21 is a box-shaped structure with an open upper part. The driver 24 is installed in the box-shaped structure. The driver 24 is electrically connected to the electric roller 221, and the conveyor belt 223 closes the opening. The driver 24 drives the electric roller 221 to rotate, and then drives the driven roller 222 and the conveyor belt 223 to rotate, so that the conveyor belt 223 realizes the conveying of the items. Optionally, the guard plate 23 is provided with a wire passing hole 231, and the connecting wire of the electric roller 221 passes through the wire passing hole 231 and is connected to the driver 24.

[0041] Optionally, in this embodiment, as Figure 5 and Figure 6 shown, the conveying assembly 22 further includes a support frame 224. The support frame 224 is fixedly connected to the base 21. The electric roller 221 and the driven roller 222 are arranged at intervals along the first direction on the support frame 224. The sorting trolley 2 further includes two detection components 25. The two detection components 25 are respectively located at both ends of the sorting trolley 2 along the first direction. Each detection component 25 includes a mounting plate and a sensor (not shown in the figure). The mounting plate is fixedly connected to the support frame 224, and the sensor is fixed to the mounting plate. The sensor is used to detect whether the items on the conveyor belt 223 extend out of the sorting trolley 2 along the first direction. If the sensor detects that the items on the conveyor belt 223 extend outside the sorting trolley 2, the electric roller 221 is controlled to rotate in the reverse direction to retract the extended items back onto the conveyor belt 223 to prevent the items from colliding with other structures when the sorting trolley 2 moves along the second direction. In this embodiment, the guard plate 23 is also fixedly connected to the support frame 224, further ensuring the stability and reliability of the installation and fixation of the guard plate 23.

[0042] Optionally, in this embodiment, as Figures 5 to 7As shown in the figure, two sets of traveling wheel assemblies 26 supported by two support members 13 respectively are provided on the base 21. Each set of traveling wheel assemblies 26 includes at least one traveling wheel 261 that rolls along the corresponding support member 13. The guide rail 31 is located between the two support members 13 and is arranged in parallel and at intervals with both support members 13. With the above arrangement, the traveling wheels 261 on the sorting cart 2 roll on the support members 13, reducing the friction when the sorting cart 2 moves relative to the rack 1 in the second direction. Optionally, each set of traveling wheel assemblies 26 includes two traveling wheels 261 arranged at intervals in the second direction.

The sorting cart 2 moves along the second direction and is used to send the items into the compartments. The sorting device provided in this embodiment sorts the items by applying the above-mentioned reciprocating sorting machine 10, making the structure of the sorting device simple, the cost low, and it is easy to process and produce.

[0044] Optionally, as Figure 8 shown, in this embodiment, the scanning device 40 is arranged above the upper bagging machine 20, and the scanning device 40 scans the items after the items are placed on the upper bagging machine 20.
