Description

Technical Field

[0001] The present invention relates to the technical field of sorting machines, and in particular to a double-side sorting system. Background Art

[0002] The double-sided sorting system is a device that uses a main drive device to drive the conveying device to make a closed loop motion. During sorting, the main drive device drives the conveying device to move in a set direction. After moving to the corresponding sorting port, the conveyor belt on the conveying device moves in a direction perpendicular to the movement direction of the conveying device, so that the items to be sorted on it can flow out from the left or right side of the sorting system. Since the conveyor belt can move in a direction close to the left or right side of the sorting system, the items to be sorted on it can flow out from the left and right sides of the sorting system, which can greatly improve the sorting efficiency and effectively save floor space.

[0003] Specifically, in order to realize double-sided sorting, a guide device is provided on the upper part of the sorting system, and the guide device includes a guide base and a toggle structure. The guide base is provided with a first guide groove and a second guide groove which are cross-arranged and connected. The first guide groove and the second guide groove are used to cooperate with the driving rod on the transmission belt conveyor device to drive the conveyor belt to move close to the left or right side of the sorting system. The toggle structure includes a first blocking block, a second blocking block and a transmission mechanism. The first blocking block and the second blocking block are both rotatably arranged on the top of the guide base. The first blocking block and the second blocking block are arranged opposite to each other, and the first blocking block and the second blocking block are linked by the transmission mechanism. When When the driving rod slides into the first guide groove from one end close to the first blocking block, the driving rod drives the first blocking block to swing, so that the first blocking block swings to a position closing a guide opening of the second guide groove at the intersection. At the same time, the first blocking block drives the second blocking block through the transmission mechanism, so that the second blocking block swings to a position closing another guide opening of the second guide groove at the intersection, so that the driving rod is not blocked by the blocking block on the path of the first guide groove, and the two guide openings of the second guide groove are closed at the same time, so that the driving rod slides in the direction of the first guide groove, and the driving rod is prevented from entering the second guide groove, so that the items to be sorted on the transmission belt can be sorted to the left or right side of the sorting system.

[0004] However, the guide structure currently used in the double-sided sorting system needs to be equipped with a transmission mechanism to link the first blocking block and the second blocking block. The transmission mechanism is often a complex gear mechanism or a connecting rod mechanism, which leads to the defects of complex structure and high cost. Therefore, it is urgent to improve the structure of the existing double-sided sorting system. Summary of the invention

DETAILED DESCRIPTION

[0057] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0058] See also Figure 1 , shows a double-sided sorting system according to a preferred embodiment of the present invention, including a frame 10, a driving device 20, a conveying device 30, a feeding device 40, an adjusting device 50 and a tensioning device 60.

[0059] Among them, a support track 11 is provided on the frame 10 for the smooth operation of the conveying device 30. In this embodiment, the support track 11 includes a first support guide rail and a second support guide rail which are separated by a distance laterally. The outer contours of the first support guide rail and the second support guide rail on the vertical plane are both rounded rectangles (also called runway shapes), so that the conveying device 30 can perform a circular motion with a closed loop trajectory on the support track 11.

[0060] See also Figure 1 as well as Figure 2 The driving device 20 serves as a power source for driving the conveying device 30, and is used to drive the conveying device 30 to move on the supporting rail 11. In this embodiment, the driving device 20 includes a motor 21, two pairs of sprockets 22 and two chains 23. The motor 21 is fixedly arranged on the frame 10, and the two sprockets 22 in each pair of sprockets 22 are respectively located at the two ends of the frame 10, and the adjacent two sprockets 22 in each different pair of sprockets 22 are arranged at a lateral interval on the frame 10, and the adjacent two sprockets 22 in each different pair of sprockets 22 are rotatably installed on the frame 10 through a transmission shaft 24, wherein a transmission shaft 24 is driven and connected to the motor 21, each chain 23 is wound around a pair of sprockets 22, and the chain 23 is connected to the conveying device 30, so that by driving the motor 21 to rotate, the chain 23 can be driven to rotate, thereby driving the conveying device 30 to circulate.

[0061] See also Figure 2 as well as Figure 3 In the present embodiment, the conveying device 30 includes a conveyor belt 31, a support frame 32 and a linkage structure. The conveyor belt 31 is movably arranged on the support frame 32 so that it can reciprocate relative to the support frame 32 toward the opposite sides of the frame 10 (that is, reciprocate in the width direction of the frame 10). The conveyor belt 31 is used to carry objects to be sorted. A pair of running wheels (not shown in the figure) are arranged at both ends of the bottom of the support frame 32. The running wheels arranged at both ends of the bottom of the support frame 32 respectively cooperate with the first support guide rail and the second support guide rail to enable the conveying device 30 to move smoothly on the support rail 11. The linkage structure can be slidably arranged on the bottom of the support frame 32 and fixed to the conveyor belt 31, so as to drive the conveyor belt 31 to reciprocate toward the opposite sides of the frame 10.

[0062] Continue to see Figure 3 In this embodiment, the linkage structure includes a slider 33, a guide rod 34 and a guide wheel 35. The slider 33 is fixedly connected to the conveyor belt 31. The slider 33 is slidably matched with the slide rail on the bottom of the support frame 32, so that the slider 33 can reciprocate between the two ends of the bottom of the support frame 32. The first end of the guide rod 34 is fixed to the slider 33, and the second end of the guide rod 34 passes through the guide wheel 35, and the guide wheel 35 is rotatably mounted on the guide rod 34.

[0063] Continue to see Figure 1 as well as Figure 2 The unloading device 40 is arranged on the top of the frame 10 and is located between the upper part of the first supporting rail and the upper part of the second supporting rail. The unloading device 40 is used to enable the conveying device 30 to unload the objects to be sorted on opposite sides of the direction perpendicular to its walking direction (that is, to unload the objects to be sorted along the width direction of the frame 10). The unloading device 40 includes a first unloading rail, a second unloading rail and a toggle structure 432.

[0064] In order to realize double-sided sorting, the first unloading track and the second unloading track intersect and communicate with each other, and the outlet end of the first unloading track and the inlet end of the second unloading track are both located on the first side (the first side corresponds to Figure 1 The first feeding track has a lead-in end and the second feeding track has a lead-out end. The second side corresponds to the right side of the reference direction. Figure 1 The first side and the second side are laterally spaced apart by a distance.

[0065] Specifically, the first unloading track is used to cooperate with the linkage structure to guide the linkage structure from the second side to the first side during the forward movement of the conveying device 30. During this process, the conveyor belt 31 moves with the linkage structure so that the conveyor belt 31 unloads the objects to be sorted that it carries to the first sorting port located on the right side of the frame 10.

[0066] The second unloading track is used to cooperate with the linkage structure to guide the linkage structure from the first side to the second side when the conveying device 30 moves forward. During this process, the conveyor belt 31 moves with the linkage structure to enable the conveyor belt 31 to unload the objects to be sorted that it carries to the second sorting port located on the left side of the frame 10.

[0067] Continue to see Figure 1 as well as Figure 2 The toggle structure 432 is arranged at the intersection between the first unloading track and the second unloading track. The toggle structure 432 includes a connecting base 4321, a first blocking component 4322, a second blocking component 4323 and a third blocking component 4324. The connecting base 4321 can be rotatably arranged, and the first blocking component 4322, the second blocking component 4323 and the third blocking component 4324 are all arranged on the connecting base 4321.

[0068] The toggle structure 432 can switch between the first position and the second position as the connecting base 4321 rotates. When the toggle structure 432 is in the first position, the first blocking component 4322 swings to close the first guide opening of the second unloading track at the intersection, the third blocking component 4324 swings to close the second guide opening of the second unloading track at the intersection, and the second blocking component 4323 swings to be offset from the first unloading track to make the first unloading track conductive, so that the first unloading track is not blocked by any blocking components, and at the same time, the first guide opening and the second guide opening of the second unloading track are closed to prevent the linkage structure running on the first unloading track from entering the second unloading track, thereby ensuring that the linkage structure can move into place on the first unloading track to ensure that the objects to be sorted are unloaded to the first sorting opening located on the right side of the frame 10.

[0069] When the toggle structure 432 is in the second position, the second blocking component 4323 swings to close the first guide opening of the first unloading track at the intersection, the third blocking component 4324 swings to close the second guide opening of the first unloading track at the intersection, and the first blocking component 4322 swings to be offset from the second unloading track to make the second unloading track conductive, so that the second unloading track is not blocked by any blocking components, and at the same time, the first guide opening and the second guide opening of the first unloading track are closed to prevent the linkage structure running on the second unloading track from entering the first unloading track, thereby ensuring that the linkage structure can move into place on the second unloading track to ensure that the objects to be sorted are unloaded to the second sorting opening on the left side of the frame 10.

[0070] Because the first blocking component 4322, the second blocking component 4323 and the third blocking component 4324 on the toggle structure 432 used in the double-sided sorting system are all integrated on a connecting base 4321, when any one of the first blocking component 4322, the second blocking component 4323 and the third blocking component 4324 is toggled, the entire toggle structure 432 swings relative to the rotation point, so that any one of the two material discharge tracks is connected, and the two guide ports at the intersection of the other are closed, so that the linkage structure running on the connected material discharge track can run into place in the direction of the material discharge track. The double-sided sorting system does not require a complex transmission mechanism to link the first blocking component 4322, the second blocking component 4323 and the third blocking component 4324, and has a simpler structure and lower cost.

[0071] See also Figure 1 as well as Figure 2 In the present embodiment, a plurality of unloading devices 40 are provided, and the plurality of unloading devices 40 are sequentially distributed along the moving direction of the conveying device 30. In the present embodiment, the first unloading track and the second unloading track on adjacent different unloading devices 40 are connected to each other.

[0072] Continue to see Figure 2In this embodiment, the inlet end of each first unloading track is provided with a first lane-changing mechanism 44, which is used to adjust the moving direction of the linkage structure, so as to guide the linkage structure to the first unloading track or keep the linkage structure on the second side during the movement of the conveying device 30; the inlet end of each second unloading track is provided with a second lane-changing mechanism 45, which is used to adjust the moving direction of the linkage structure, so as to guide the linkage structure to the second unloading track or keep the linkage structure on the first side during the movement of the conveying device 30. In this way, the conveying device 30 can transport the objects to be sorted carried thereon to the corresponding sorting port.

[0073] Figure 4-Figure 8 In this embodiment, the material discharging device 40 further includes a guide base 431, wherein the guide base 431 and the toggle structure 432 constitute a guide device 43, the guide base 431 is arranged at the intersection between the first material discharging track and the second material discharging track, and the guide base 431 is provided with a first guide groove 4311 and a second guide groove 4312 which intersect and communicate with each other, see Figure 2 Both ends of the first guide groove 4311 are connected to a first unloading guide rail 41, and the first unloading guide rails 41 and the first guide groove 4311 arranged at both ends of the first guide groove 4311 form the above-mentioned first unloading track, and both ends of the second guide groove 4312 are connected to a second unloading guide rail 42, and the second unloading guide rails 42 and the second guide groove 4312 arranged at both ends of the second guide groove 4312 form the above-mentioned second unloading track.

[0074] Specifically, the connecting base 4321 is rotatably provided on the guide base 431, and when the toggle structure 432 is in the first position, the first blocking component 4322 swings to close the first guide opening of the second guide groove 4312 at the intersection, the third blocking component 4324 swings to close the second guide opening of the second guide groove 4312 at the intersection, and the second blocking component 4323 swings to stagger with the first guide groove 4311 to make the first guide groove 4311 conductive; when the toggle structure 432 is in the second position, the second blocking component 4323 swings to close the first guide opening of the first guide groove 4311 at the intersection, the third blocking component 4324 swings to close the second guide opening of the first guide groove 4311 at the intersection, and the first blocking component 4322 swings to stagger with the second guide groove 4312 to make the second guide groove 4312 conductive.

[0075] See also Fig. 9In the present embodiment, a first positioning notch 4313 and a second positioning notch 4314 which are arranged opposite to each other are provided on the guide base 431. The first positioning notch 4313 is located on the side wall of the first guide groove 4311 and is close to the second guide opening of the first guide groove 4311. The second positioning notch 4314 is located on the side wall of the second guide groove 4312 and is close to the second guide opening of the second guide groove 4312. A positioning portion is provided on the third blocking component 4324, and the positioning portion extends to the intersection of the first guide groove 4311 and the second guide groove 4312. When the first guide groove 4311 is connected, the first side portion of the positioning portion can cooperate with the second positioning notch 4314. When the second guide groove 4312 is connected, the second side portion of the positioning portion can cooperate with the first positioning notch 4313. In this way, the rotation angle of the third blocking component 4324 is limited, thereby playing a role in reliably positioning the toggle structure 432.

[0076] Continue to see Fig. 9 In the present embodiment, the first positioning notch 4313 and the second positioning notch 4314 are both L-shaped, and the shapes of the first side portion and the second side portion of the positioning portion are respectively adapted to the shapes of the first positioning notch 4313 and the second positioning notch 4314. When the first guide groove 4311 is connected, the first side portion of the positioning portion cooperates with the second positioning notch 4314, and when the second guide groove 4312 is connected, the second side portion of the positioning portion cooperates with the first positioning notch 4313.

[0086] Specifically in this embodiment, when the conveying device 30 needs to unload the objects to be sorted at the first sorting port corresponding to the position of the unloading device 40, the conveying device 30 is Figure 1 The guide wheel 35 on the conveying device 30 first enters the first unloading guide rail 41 near the inlet end of the first unloading guide rail, and the guide wheel 35 abuts against the first unloading guide rail 41, then the guide wheel 35 disengages from the first unloading guide rail 41, and the second end of the guide rod 34 cooperates with the first guide groove 4311, then the guide rod 34 disengages from the first guide groove 4311, and the guide wheel 35 abuts against the first unloading guide rail 41 near the outlet end of the first unloading guide rail, thereby adjusting the position of the linkage structure from the second side to the first side during the movement of the conveying device 30, so that the conveyor belt 31 moves with the linkage structure to realize the conveying of the objects to be sorted carried by the conveyor belt 31 to the first sorting port located on the right side of the frame 10.

[0087] When the conveying device 30 needs to unload the objects to be sorted at the second sorting port corresponding to the position of the unloading device 40, the conveying device 30 is Figure 1 The guide wheel 35 on the conveying device 30 first enters the second material discharge guide rail 42 near the introduction end of the second material discharge track, and the guide wheel 35 abuts against the second material discharge guide rail 42, then the guide wheel 35 disengages from the second material discharge guide rail 42, and the second end of the guide rod 34 cooperates with the second guide groove 4312.

In this way, the linkage structure can also be guided, and finally bilateral sorting can be achieved.

[0089] See also Figure 1 In this embodiment, the adjustment device 50 is installed on the frame 10 and is located below the unloading device 40. The adjustment device 50 is located between the lower part of the first support rail and the lower part of the second support rail. The adjustment device 50 is used to adjust the position of the linkage structure of the conveying device 30 before entering the unloading device 40 to the first side or the second side, so that the linkage structure can move on the first unloading track or the second unloading track after the conveying device 30 enters the unloading device 40, thereby realizing the conveying of the objects to be sorted to the first sorting port located on the right side of the frame 10 or the second sorting port located on the left side of the frame 10.

[0090] Fig.12 for Figure 1The bottom view of the adjustment device 50 in the double-sided sorting system shown in FIG. Figure 1 The adjustment device 50 in the double-sided sorting system shown is projected from bottom to top), see Fig.12 The adjustment device 50 includes a lane-changing guide rail 51, a directional guide rail 52, a third lane-changing mechanism 53 and a lane-dividing structure 54, which are sequentially distributed along the moving direction of the conveying device 30; wherein the introduction end of the lane-changing guide rail 51 is located on the first side, the outlet end of the lane-changing guide rail 51 is located on the second side, and the directional guide rail 52 is arranged along the second side; the lane-dividing structure 54 includes a first lane-dividing guide rail 541 and a second lane-dividing guide rail 542; the lane-changing guide rail 51 is used to abut against the linkage structure to guide the linkage structure from the first side to the directional guide rail 52 located on the second side during the linkage structure moving forward with the conveying device 30; the directional guide rail 52 is used to abut against the linkage structure to guide the linkage structure from the first side to the directional guide rail 52 located on the second side during the linkage structure moving forward with the conveying device 30 and passing through the directional guide rail 52 The third lane-changing mechanism 53 is used to adjust the moving direction of the linkage structure moved out from the lead-out end of the directional guide rail 52, so that the linkage structure moves to the first lane-dividing guide rail 541 or the second lane-dividing guide rail 542; the first lane-dividing guide rail 541 is colinear with the directional guide rail 52, and the first lane-dividing guide rail 541 is used to abut against the linkage structure, so that the linkage structure is maintained on the second side during the process in which the linkage structure moves forward with the conveying device 30 and passes through the first lane-dividing guide rail 541; the lead-out end of the second lane-dividing guide rail 542 is located on the first side, and the second lane-dividing guide rail 542 is used to abut against the linkage structure, so that the linkage structure is guided from the second side to the first side during the process in which the linkage structure moves forward with the conveying device 30.

[0091] See also Fig.12 , the working principle of the adjustment device 50 is as follows:

[0092] The position of the linkage structure on the conveying device 30 before being introduced into the adjustment device 50 is defined as the initial position, and the position of the linkage structure on the conveying device 30 after being guided out of the adjustment device 50 is defined as the set position;

[0093] When the initial position and the set position of the linkage structure are both at the second side, the linkage structure passes through the directional guide rail 52 and the first lane-dividing guide rail 541 in sequence and always remains at the second side without changing lanes;

[0094] When the initial position of the linkage structure is the second side and the set position of the linkage structure is the first side, the linkage structure first moves along the directional guide rail 52 under the guidance of the directional guide rail 52, and after passing through the third lane-changing mechanism 53, the linkage structure is guided to the second lane-dividing guide rail 542, and the moving direction is changed under the guidance of the second lane-dividing guide rail 542, so as to achieve the purpose of adjusting the position of the linkage structure to the first side;

[0095] When the initial position of the linkage structure is the first side and the set position of the linkage structure is the second side, the linkage structure first moves on the lane-changing guide rail 51, changes lanes to the directional guide rail 52 under the guidance of the lane-changing guide rail 51, and moves along the directional guide rail 52 and the first lane-dividing guide rail 541 in sequence to adjust its position to the second side;

[0096] When the initial position and the set position of the linkage structure are both the first side, the linkage structure first moves on the lane changing guide rail 51, changes lanes to the directional guide rail 52 under the guidance of the lane changing guide rail 51, and is then guided to the second lane dividing guide rail 542 through the lane changing mechanism, so as to achieve the purpose of adjusting the position of the linkage structure to the first side.

[0097] Because the directional guide rail 52 and the first branch guide rail 541 are arranged in the same line, the adjustment device 50 can enable the linkage structure to maintain its initial position unchanged when the set position of the linkage structure is on the same side as the directional guide rail 52 and the first branch guide rail 541, thereby avoiding lane changes and reducing the number of operations of the linkage structure, thereby extending the service life of the linkage structure.

[0098] In this embodiment, the lane-changing guide rail 51 , the directional guide rail 52 , the first lane-dividing guide rail 541 , and the second lane-dividing guide rail 542 are located on the same horizontal plane.

[0099] Continue to see Fig.12 In the present embodiment, the lane-changing guide rail 51 and the second lane-dividing guide rail 542 are in an eight-shaped shape.

[0101] Continue to see Figure 13-14 The third lane changing mechanism 53 is also provided with a lane changing base 531, a driving mechanism installed on the lane changing base 531, and a block 532 drivingly connected to the driving mechanism. The block 532 is accommodated at the connection between the first guide groove 5311 and the second guide groove 5312. One end of the block 532 is pivotally connected to the lane changing base 531 through a pivot shaft 533, so that the driving mechanism can drive the block 532 to swing, so that the other end of the block 532 switches between blocking the first guide groove 5311 and blocking the second guide groove 5312, so as to guide the adjusted object to the second lane guide rail 542 or the first lane guide rail 541.

[0102] See also Figure 5 In this embodiment, the driving mechanism is a cylinder fixed on the lane changing base 531 , and the movable end of the cylinder is connected to the stopper 532 .

[0103] In this embodiment, the specific structures of the first lane changing mechanism 44 and the second lane changing mechanism 45 may refer to the specific structure of the third lane changing mechanism 53 .

The tensioning device 60 is used to adjust the position of the sprocket 22 to adjust the distance between a pair of sprockets 22 arranged in the length direction of the frame 10, so that the chain 23 can be kept tensioned, thereby ensuring that the double-sided sorting system can operate normally.

[0105] Specifically, the tensioning device 60 includes a support seat 61 and an adjusting screw 62. The support seat 61 can be slidably installed on the inner side of the frame 10 so that the support seat 61 can move along the length direction of the frame 10.

The adjusting screw 62 is screwed to the outer side of the frame 10. The adjusting screw 62 is arranged along the length direction of the frame 10, and the adjusting screw 62 is screwed to the support seat 61. In this way, by rotating an adjusting screw 62, the corresponding support seat 61 can be driven to move forward and backward along the length direction of the frame 10, thereby changing the spacing between a pair of sprockets 22 arranged in the length direction of the frame 10, thereby realizing the tensioning of the chain 23.

[0106] Continue to see Fig.15 The frame 10 is provided with a slide groove 13 arranged along the length direction of the frame 10, and the support seat 61 is provided with a guide column.

[0107] Continue to see Fig.15 In this embodiment, a third support rail 12 is provided on the inner side of the frame 10. The third support rail 12 is located at the bottom of the support seat 61 to provide support for the support seat 61 to bear the weight of the sprocket 22, the transmission shaft 24 and the conveying device 30, thereby ensuring that the conveying device 30 runs more stably during the turning process. At the same time, a track is provided for the tensioning process of the support seat 61 moving forward and backward, so that the movement of the support seat 61 is smoother and more stable.
