Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics equipment, especially relates to a detection assembly and sorting machine. BACKGROUND

[0002] In the prior art, the sorting machine comprises a track, a trolley moving along the track and a driving motor for driving the trolley to move, wherein the driving motor usually adopts a linear motor, the linear motor comprises a primary plate and a secondary plate, the primary plate of the linear motor is fixedly arranged along the track, the secondary plate of the linear motor is installed on the trolley, and the primary plate cooperates with the secondary plate to realize non-contact driving, thereby driving the trolley to move circularly along the track. Since the secondary plate and the primary plate of the linear motor are arranged in a relative spacing manner along the up-down direction, when the trolley and track parts are worn due to long-term use of the sorting machine, the trolley may sink under the action of gravity, which is easy to cause the air gap between the secondary plate and the primary plate to decrease, even to form zero air gap, resulting in mutual friction between the primary plate and the secondary plate, and finally causing damage to the linear motor.

[0003] Therefore, the patent with the publication number CN222098789U provides a detection assembly, which comprises a detection plate and a sensor, the detection plate comprises a sensing end and a triggering end, the sensing end is located between the primary plate and the secondary plate in the vertical direction, and when the secondary plate sinks and contacts the sensing end, the sensing end can drive the triggering end to move; the sensor is arranged in a relative spacing manner with the triggering end, and the sensor is used to output a detection signal of the position or state abnormality of the triggering end when the triggering end moves. When the sensor outputs the detection signal of the position or state abnormality of the triggering end, the linear motor is controlled to stop driving the trolley to move, so as to avoid the trolley from damaging the linear motor. However, in the detection assembly, once the secondary plate collides with the sensing end, the sensing end is easy to be bent under the action of strong impact force generated by the collision, thereby causing the detection plate to deform and unable to reset, affecting continuous detection, and poor reliability.

[0045] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0046] Please refer to Figures 1 to 4 The detection assembly 40 provided by the embodiment comprises a rack 1, a detection piece 2, a stop piece 3, a first elastic piece 4 and a sensor 5. The detection piece 2, the stop piece 3, the first elastic piece 4 and the sensor 5 are all installed on the rack 1. The detection piece 2 and the stop piece 3 can rotate relative to the rack 1. The detection piece 2 has an initial position and a detection position. When the detection piece 2 is located at the initial position, the detection piece 2 is separated from the sensor 5. When the detection piece 2 is located at the detection position, the detection piece 2 cooperates with the sensor 5. The stop piece 3 can cooperate with the detection piece 2 located at the detection position and lock the detection piece 2 at the detection position under the action of gravity and / or external elastic force. The first elastic piece 4 is connected with the detection piece 2. The first elastic piece 4 is configured to apply a first elastic force to the detection piece 2 to make the detection piece 2 rotate to the initial position. When the detection piece 2 is located at the initial position, the detection piece 2 is separated from the sensor 5, and the sensor 5 outputs a first signal. When the detection piece 2 rotates to the detection position under the action of external force (for example, the impact force generated by the secondary plate sinking and colliding with the detection piece 2), the detection piece 2 cooperates with the sensor 5, and the sensor 5 outputs a second signal. At this time, the stop piece 3 cooperates with the detection piece 2 under the action of gravity and / or external elastic force and locks the position of the detection piece 2, so that the sensor 5 continuously outputs the second signal, thereby timely and reliably reminding that a fault occurs. When the fault is eliminated, the operator rotates the stop piece 3 to unlock the position of the detection piece 2. The detection piece 2 resets to the initial position under the action of the first elastic force of the first elastic piece 4, and detection can continue. Therefore, compared with the detection assembly in the prior art, the detection piece 2 in the detection assembly 40 provided by the embodiment will not deform during detection, can reset smoothly, can continue detection, will not affect reuse, and has good reliability.

[0047] Optionally, sensor 5 can be a micro switch or a photoelectric sensor.

[0048] Alternatively, please refer to Figures 1 to 4 In this embodiment, the detection element 2 is rotatably connected to the frame 1 via a rotating shaft 61. The detection element 2 includes a sensing part 211, a blocking part 221, and a detection part 24. The stop member 3 is rotatably connected to the frame 1 via a support shaft 62. The stop member 3 includes a stop part 311. When the detection element 2 is in the initial position, the stop member 3 overlaps with the detection element 2, and the detection part 24 is separated from the sensor 5. During the process of the external force acting on the sensing part 211 to rotate the detection element 2 from the initial position to the detection position, the stop member 3, driven by the detection element 2, rotates around the axis of the support shaft 62 along a first direction (e.g., Figure 2 (In the direction indicated by the middle arrow oa) rotates; when the detection element 2 rotates to the detection position, the detection part 24 cooperates with the sensor 5, and the stop 3 rotates around the axis of the support shaft 62 in the second direction (as shown by the middle arrow oa) under the action of gravity and / or external elastic force. Figure 2 The first direction is opposite to the second direction. The detector 2 rotates from the detection position to the initial position in the direction indicated by the middle arrow ob, and the stop part 311 can abut against the blocking part 221 to lock the detector 2 in the detection position. With this configuration, when the detection element 2 is in the initial position, the stop 3 overlaps with the detection element 2. As the detection element 2 rotates from the initial position to the detection position under the action of an external force, the detection element 2 rotates around the axis of the rotating shaft 61 towards the detection position. At the same time, the detection element 61 drives the stop 3, which overlaps with it, to rotate around the axis of the support shaft 62 in the first direction. As the detection element 2 gradually approaches the detection position, the overlapping area between the stop 3 and the detection element 2 gradually decreases. When the detection element 2 rotates to the detection position, the overlapping area between the stop 3 and the detection element 2 is zero, that is, the stop 3 and the detection element 2 no longer overlap. Under the action of gravity or external elastic force, the stop 3 rotates around the axis of the support shaft 62 in the second direction to the path on which the detection element 2 rotates from the detection position to the initial position, so as to prevent the detection element 2 from rotating to the initial position and to stably lock the detection element 2 in the detection position. In this embodiment, an exemplary scheme is provided where, when the detection element 2 is in the detection position, the stop element 3 rotates downward along the second direction under its own weight to the path along which the detection element 2 rotates from the detection position to the initial position. In other embodiments, when the detection element 2 is in the detection position, the stop element 3 may also rotate downward along the second direction under the action of an external elastic force or under the combined action of its own weight and an external elastic force to the path along which the detection element 2 rotates from the detection position to the initial position.

[0049] It should be noted that when an external force is applied to the sensing part 211 and the detection element 2 rotates from the initial position to the detection position, the stop 3, driven by the detection element 2, needs to overcome gravity and / or external elastic force when it rotates along the first direction.

[0050] Optionally, in the embodiment, the detection part 24 is elastically matched with the sensor 5, so that the detection position specifically refers to a range interval, for example, the detection position includes a first limit position point, a second limit position point and any position point between the first limit position point and the second limit position point, wherein the first limit position point is closer to the initial position than the second limit position point. When the detection piece 2 is located at the first limit position point, the stop piece 3 can be just rotated to the path of the detection piece 2 rotating from the detection position to the initial position in the second direction, and at this time, the stop part 311 is just in abutment with the blocking part 221; when the detection piece 2 rotates away from the first limit position point and towards the second limit position point, the stop part 311 is in a separated state from the blocking part 221. In other embodiments, the detection position can also be set as a specific position point as needed, when the detection piece 2 is located at the detection position, the stop piece 3 is just rotated to the path of the detection piece 2 rotating from the detection position to the initial position in the second direction, and at this time, the stop part 311 is just in abutment with the blocking part 221.

[0051] Optionally, referring to Figures 1 to 4 , the detection part 24 is arranged adjacent to the rotating shaft 61, so that the detection part 24 can be matched with the sensor 5 to timely send a prompt signal when the detection piece 2 rotates a small angle.

[0052] Optionally, referring to Figures 1 to 4 , in the embodiment, the first elastic piece 4 is a tension spring, the first end of the tension spring is connected with the supporting shaft 62, and the second end is connected with the detection piece 2; in other embodiments, the first elastic piece 4 can also be set as a torsion spring, the torsion spring is sleeved on the rotating shaft 61, one torsion arm of the torsion spring is connected with the rack 1, and the other torsion arm is connected with the detection piece 2. After the fault is eliminated, the stop piece 3 can be manually rotated in the first direction to make the stop piece 3 exit the path of the detection piece 2 rotating from the detection position to the initial position, that is, the stop part 311 is separated from the blocking part 221, so that the locking of the position of the detection piece 2 is released, and under the action of the first elastic force of the first elastic piece 4, the detection piece 2 is rotated to the initial position.

[0053] Optionally, referring to Figure 1 and Figure 2The rack 1 comprises two side plates 11 arranged oppositely and spaced apart, and a bottom plate 12 connected between the two side plates 11, the bottom plate 12 and the two side plates 11 together forming a first accommodating space; the detection member 2 and the stop member 3 are both located in the first accommodating space, the detection member 2 is rotatably connected to at least one of the two side plates 11 through a rotating shaft 61, both ends of a supporting shaft 62 are supported by the two side plates 11, and the stop member 3 is sleeved on the supporting shaft 62. In this way, the detection member 2 and the stop member 3 are both located in the first accommodating space, so that the rotation of the detection member 2 and the stop member 3 can be prevented from being interfered by other structures, and the reliable work of the detection assembly 40 can be ensured. Preferably, the sensor 5 is installed on the bottom plate 12, and the sensing end of the sensor 5 is located in the first accommodating space, so that the sensing end of the sensor 5 can be prevented from being mistakenly touched by other structures, and the detection accuracy of the detection assembly 40 can be ensured.

[0054] Optionally, please refer to Figure 3 and Figure 4 When the detection member 2 is located at the initial position, the stop member 3, the detection member 2 and the bottom plate 12 are sequentially abutted, the stop member 3 is spaced apart from the bottom plate 12, the initial position of the detection member 2 can be limited by the bottom plate 12, the blocking part 221 is abutted against the bottom plate 12 by the first elastic force of the first elastic member 4, the detection member 2 is pressed against the bottom plate 12 by the stop member 3 under the action of gravity and / or external elastic force, and the detection member 2 can be stably located at the initial position; when the detection member 2 is located at the detection position, the stop member 3 is rotated to a position abutting against the bottom plate 12 in a second direction under the action of gravity and / or external elastic force, the position of the stop member 3 is limited by the bottom plate 12, the position of the stop member 3 is stable, and the detection member 2 is stably limited at the detection position. In other embodiments, a limiting column can be arranged on the side plate 11, and the limiting column is used for abutting against the detection member 2 located at the initial position.

[0055] Optionally, please refer to Figure 1 and Figure 2The detection piece 2 comprises a first plate 21, a second plate 22 and a third plate 23. The first plate 21 and the second plate 22 are connected at an angle. The third plate 23 is connected to the first plate 21 and the second plate 22 at an angle. The first plate 21, the second plate 22 and the third plate 23 form a second accommodating space. The third plate 23 is rotatably connected to the rack 1 through a rotating shaft 61. An induction portion 211 is formed at an end of the first plate 21 away from the second plate 22. A blocking portion 221 is formed at an end of the second plate 22 away from the first plate 21. A detection portion 24 is connected to the first plate 21 and located in the second accommodating space. In this way, the detection portion 24 is located in the second accommodating space formed by the first plate 21, the second plate 22 and the third plate 23. The detection portion 24 is protected by the second accommodating space, so that the detection portion 24 is not interfered by other structures, thereby ensuring reliable work of the detection assembly 40. Specifically, in the embodiment, the first plate 21 and the second plate 22 are connected perpendicularly, and the third plate 23 is connected to the first plate 21 and the second plate 22 perpendicularly. In other embodiments, the connection angle of the first plate 21 and the second plate 22, the connection angle of the third plate 23 and the first plate 21, and the connection angle of the third plate 23 and the second plate 22 can be set according to actual needs. Preferably, the detection piece 2 comprises two third plates 23. The two third plates 23 are parallel and spaced apart. The first plate 21 and the second plate 22 are connected between the two third plates 23. The two third plates 23 are rotatably connected to the two side walls 11 through two rotating shafts respectively.

[0056] Optionally, referring to Figures 2 to 4 The stop piece 3 comprises a support plate 31. A first end of the support plate 31 is sleeved with the support shaft 62. A stop portion 311 is formed at a second end of the support plate 31. When the detection piece 2 is located at the initial position, the support plate 31 extends into the second accommodating space. Under the action of its own gravity, the lower surface of the support plate 31 directly or indirectly overlaps the upper surface of the second plate 22. In this way, during the rotation of the detection piece 2 from the initial position to the detection position, the upper surface of the second plate 22 gradually lifts the support plate 31 upward to drive the support plate 31 to rotate around the axis of the support shaft 62 in the first direction, and until the second plate 22 no longer overlaps the lower surface of the support plate 31. Then the support plate 31 rotates downward in the second direction until the lower surface of the support plate 31 is attached to the bottom plate 12. At this time, the support plate 31 is located on the path of the detection piece 2 rotating from the detection position to the initial position. The stop portion 311 prevents the detection piece 2 from rotating to the initial position under the action of the first elastic force, thereby locking the detection piece 2 at the detection position.

[0057] Optionally, referring to Figure 2The stopper 3 comprises two support plates 31 which are spaced apart. When the detection member 2 is located at the detection position, the second ends of the two support plates 31 abut against the end of the second plate 22 at the same time, so that the position of the detection member 2 is locked more reliably.

[0058] Optionally, please refer to Figure 2 The stopper 3 further comprises a connecting plate 32 which is connected between the two support plates 31. In this way, the structural strength of the stopper 3 is enhanced. Specifically, in the embodiment, a scheme is exemplarily given that when the detection member 2 is located at the initial position, the lower surface of the support plate 31 is indirectly supported on the upper surface of the second plate 22 through the connecting plate 32. When the detection member 2 is located at the initial position, the lower surface of the connecting plate 32 is overlapped with the upper surface of the second plate 22, and during the process that the detection member 2 rotates from the initial position to the detection position, the upper surface of the second plate 22 first gradually lifts the connecting plate 32 upward to make the two support plates 31 simultaneously rotate upward along the first direction around the axis of the support shaft 62, and until the second plate 22 is no longer overlapped with the connecting plate 32, then the stopper 3 makes the two support plates 31 simultaneously rotate downward along the second direction around the axis of the support shaft 62 under the action of its own gravity, and until the connecting plate 32 is attached to the bottom plate 12, at this time, the two support plates 31 are located on the path that the detection member 2 rotates from the detection position to the initial position, and the detection member 2 is locked at the detection position by the second ends of the two support plates 31; after troubleshooting, the operator rotates the stopper 3 along the first direction, and when the stopper 3 is separated from the path that the detection member 2 rotates from the detection position to the initial position, the detection member 2 rotates to the initial position under the action of the first elastic member 4, and then the stopper 3 is released, and under the action of its own gravity, the lower surface of the connecting plate 32 is overlapped on the upper surface of the second plate 22 again. In the embodiment, the cooperation between the connecting plate 32 and the second plate 22 makes the detection member 2 separate from the stopper 3 when the detection member 2 rotates from the initial position to the detection position, and then the stopper 3 rotates to the path that the detection member 2 rotates from the detection position to the initial position under the action of its own gravity, so that the stop portion 311 abuts against the blocking portion 221.

[0059] In other embodiments, the stopper 3 can also only comprise the support plate 31, and when the detection member 2 is located at the initial position, the lower end surface of the support plate 31 is directly overlapped on the upper surface of the second plate 22, that is, the lower surface of the support plate 31 is directly supported on the upper surface of the second plate 22.

[0060] Optionally, please refer to Figure 3 and Figure 4The detection assembly 40 further comprises an operation part 8 connected with the stopper 3 and located outside the frame 1, the operation part 8 is configured to drive the stopper 3 to rotate relative to the frame 1 so as to separate the stopper 3 from the detection piece 2, thereby unlocking the position of the detection piece 2. Specifically, in the embodiment, the operation part 8 extends to outside the first accommodating space through the gap on the bottom plate 12, and after troubleshooting, the operator can conveniently pull the operation part 8 to rotate the stopper 3 outside the first accommodating space, so as to separate the stopper 3 from the detection piece 2, thereby resetting the detection piece 2 to the initial position under the action of the first elastic force. Preferably, the operation part 8 is integrally formed with the connecting plate 32.

[0061] As one of the alternatives, as shown in Figure 5 and Figure 6 , the detection piece 2 is rotatably connected with the frame 1 through a rotating shaft 61, the detection piece 2 comprises a sensing part 211, a locking shaft 25 and a detection part 24, the stopper 3 is rotatably connected with the frame 1 through a supporting shaft 62, the stopper 3 comprises a locking hook 33; when the detection piece 2 is located at the initial position, the locking shaft 25 is separated from the locking hook 33, and the detection part 24 is separated from the sensor 5; during the rotation of the detection piece 2 from the initial position to the detection position under the action of the external force on the sensing part 211, the detection piece 2 abuts against the stopper 3, and the stopper 3 is driven by the detection piece 2 to rotate along a first direction (for example, the direction shown by an arrow oa in Figure 5 ) around the axis of the supporting shaft 62; when the detection piece 2 rotates to the detection position, the detection part 24 cooperates with the sensor 5, and the stopper 3 rotates along a second direction (for example, the direction shown by an arrow ob in Figure 5The detection member 2 is rotated to the position where the locking hook 33 is engaged with the locking shaft 25 (i.e. the direction indicated by the arrow ob) in the first direction opposite to the second direction, so as to lock the detection member 2 in the detection position. In this way, when the detection member 2 is in the initial position, the locking hook 33 is separated from the locking shaft 25; during the process that the detection member 2 is rotated from the initial position to the detection position under the action of the external force, the detection member 2 abuts against the stop member 3 and drives the stop member 3 to rotate along the first direction about the axis of the support shaft 62, and meanwhile, the relative positions of the locking shaft 25 and the locking hook 33 gradually tend to be opposite in the first direction; when the detection member 2 is in the detection position, the locking hook 33 and the locking shaft 25 are just opposite in the second direction, and then the stop member 3 is rotated along the second direction about the axis of the support shaft 62 under the action of the gravity and / or the external elastic force, until the locking hook 33 is engaged with the locking shaft 25, so as to stably lock the detection member 2 in the detection position; when the problem is solved, the operator rotates the stop member 3 in the first direction, so as to disengage the locking hook 33 from the locking shaft 25, and under the action of the first elastic force of the first elastic member 4, the detection member 2 is reset to the initial position. In this embodiment, the scheme that the stop member 3 is rotated along the second direction about the axis of the support shaft 62 to the position where the locking hook 33 is engaged with the locking shaft 25 under the action of the external elastic force when the detection member 2 is in the detection position is exemplarily given. In other embodiments, when the detection member 2 is in the detection position, the stop member 3 can also be rotated downward along the second direction to the path where the detection member 2 is rotated from the detection position to the initial position under the action of the gravity of the stop member 3 itself or the combined action of the gravity of the stop member 3 itself and the external elastic force.

[0062] Optionally, the locking hook 33 has a guide surface, and when the detection member 2 is rotated to the detection position, the locking shaft 25 abuts against the guide surface and drives the stop member 3 to rotate. Specifically, when the detection member 2 is rotated to the detection position, the locking shaft 25 contacts and pushes the guide surface, so as to drive the stop member 3 to rotate along the first direction. Preferably, the stop member 3 further comprises a support portion 34, and the locking hook 33 is arranged at the first end of the support portion 34, and the second end of the support portion 34 is rotationally connected with the rack 1 through the support shaft 62.

[0063] Optionally, the detection assembly 40 further comprises a second elastic member 7, and the second elastic member 7 is connected with the stop member 3 and is configured to apply a second elastic force to the stop member 3, so as to make the stop member 3 cooperate with the detection member 2 to lock the detection member 2 in the detection position. In this way, when the detection member 2 is in the detection position, the locking hook 33 is reliably engaged with the locking shaft 25 under the action of the elastic force of the second elastic member 7, so as to reliably lock the detection member 2 in the detection position.

[0064] Please refer to Figures 7 to 9This embodiment also provides a sorting machine, which includes a base frame 10, a trolley 20, a linear motor 30, and the aforementioned detection component 40. The trolley 20 is supported by the base frame 10, and the linear motor 30 drives the trolley 20 to move relative to the base frame 10. The detection component 40 is mounted on the base frame 10. The linear motor 30 includes a primary plate 301 and a secondary plate 302. The primary plate 301 is fixedly mounted on the base frame 10, and the secondary plate 302 is fixedly mounted on the trolley 20. In the vertical direction, the secondary plate 302 and the primary plate 301 are spaced apart by a set distance, and the sensing part 211 of the detection element 2 is located between the primary plate 301 and the secondary plate 302. In the moving direction of the trolley 20 (e.g., ...), the detection component 40 is also provided. Figure 9 (In the direction indicated by the middle arrow cd), the sensing part 211 of the detection component 40 is located upstream of the primary plate 301; when the secondary plate 302 sinks and contacts the sensing part 211, the secondary plate 302 drives the detection element 2 to rotate to the detection position. The sorting machine provided in this embodiment uses the above-mentioned detection component 40. After the detection element 2 rotates to the detection position and triggers the sensor 5 to output a corresponding signal, the sorting machine can promptly and reliably remind that a fault has occurred. After the fault is eliminated, the stop 3 is rotated to unlock the position of the detection element 2. Under the action of the elastic force of the first elastic element 4, the detection element 2 is reset to the initial position and can continue to perform detection, and the sorting machine can continue to work.

[0065] Optionally, the distance between the detection component 40 and the primary plate 301 is greater than the braking distance of the trolley 20.

[0066] Optionally, the sorting machine also includes a dust removal component. Along the moving direction of the trolley 20, the dust removal component, the detection component 40, and the primary plate 301 are arranged sequentially at intervals. The dust removal component includes a scraper 50, which is set at an angle to the moving direction of the trolley 20. With this arrangement, when the trolley 20 moves, it first passes through the dust removal component, and the scraper 50 removes foreign objects adsorbed on the secondary plate 302 or scrapes them to the side, preventing foreign objects on the secondary plate 302 from affecting its fit with the primary plate 301.
