Description

Detection mechanism and stacker

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on September 25, 2023, with application number 202322614800.X and application name “Detection Mechanism and Stacker,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of transport devices, and more particularly, to a detection mechanism and a stacker including the detection mechanism. Background Art

[0003] In related technologies, high-bay warehouses can pick up and place goods through stackers. However, due to inaccurate positioning of the stackers, the forks extended from the stackers may hit obstacles (goods or beams and other related items). Especially in the lithium battery industry, hitting expensive goods on the shelves (such as batteries or electrode coils) may cause the goods to fall and be damaged. If the batteries are charged, it may even cause a short circuit in the battery and cause a fire.

[0004] In the prior art, anti-collision structures are typically installed on forks to prevent them from directly colliding with obstacles. These structures are triggered by limit switches, which are activated by the travel of their contacts. However, existing limit switches have a long travel, requiring a significant displacement to trigger the anti-collision structure when a collision occurs. This can easily prevent the forks from stopping in time and potentially causing collisions with obstacles, resulting in damage.

[0042] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0043] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0044] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0045] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0046] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0047] The following first describes in detail the detection mechanism 100 according to an embodiment of the present application with reference to the accompanying drawings.

[0048] As shown in FIG. 1 to FIG. 8 , the detection mechanism 100 according to an embodiment of the present application includes: a position detector 10 , an anti-collision member 20 and an adjustment assembly 30 .

[0049] Specifically, the position detector 10 includes a contact 12 that is movable along a first direction. The anti-collision member 20 is movable relative to the position detector 10 along the first direction between a first state and a second state. An adjustment assembly 30 is connected between the anti-collision member 20 and the contact 12. When the anti-collision member 20 is in the first state, the contact 12 is in a trigger position and triggers the position detector 10 to transmit a collision signal. When the anti-collision member 20 is in the second state, the contact 12 is in a standby position, and the adjustment assembly 30 is movable relative to the anti-collision member 20 to adjust the distance between the trigger position and the standby position.

[0050] In other words, the detection mechanism 100 according to the embodiment of the present application is mainly composed of a position detector 10, an anti-collision member 20 and an adjustment assembly 30. The detection mechanism 100 can be installed on a movable structure for collision detection.

[0051] The position detector 10 can be mounted on a movable structure and move together with the movable structure. The position detector 10 can detect the position of the part to be detected and send a signal according to the detection result.

[0052] The position detector 10 may include a contact 12 that is movable relative to a main body 200 of the position detector 10. The object to be detected may drive the contact 12 to move, and the position detector 10 may obtain the position of the object to be detected based on the position detection of the contact 12.

[0053] It should be noted that the position detector 10 has a detection accuracy, which is related to the travel distance required for the contact 12 to trigger the position detector 10. When the contact 12 is not subjected to external force, the contact 12 can be in a free state. When the contact 12 moves a preset distance under the influence of the detected object, the contact 12 can be in a triggered state, at which point the position detector 10 can be triggered and send a collision signal. In other words, the contact 12 needs to move a corresponding distance to trigger the position detector 10 and generate collision feedback. This travel distance is the accuracy of the position detector 10.

[0054] For example, the stroke of the contact 12 may be 5 mm, that is, the position detector 10 will be triggered only when the detected member pushes the contact 12 to move 5 mm, so that the position detector 10 sends a collision signal.

[0055] The anti-collision member 20 can be connected to the position detector 10, and the anti-collision member 20 can be movable relative to the position detector 10. The anti-collision member 20 can serve as a part to be detected, pushing the contact 12 to move.

[0056] Specifically, the anti-collision member 20 is movable along a first direction between a first state and a second state. During the movement of the movable structure, the anti-collision member 20 may contact an obstacle before the movable structure and be pushed to move along the first direction, thereby pushing the contact 12 to move along the first direction to trigger the position detector 10.

[0057] When the stroke of the contact 12 is 5 mm, if the anti-collision part 20 directly pushes the contact 12 to move, the anti-collision part 20 needs to push the contact 12 to move 5 mm in order for the position detector 10 to send a collision signal, that is, the anti-collision part 20 itself needs to move 5 mm in order for the detection mechanism 100 to generate collision feedback.

[0058] An adjustment assembly 30 may be connected between the anti-collision member 20 and the position detector 10 . When the anti-collision member 20 collides with a foreign object and is displaced, the adjustment assembly 30 and the contact 12 are displaced together with the anti-collision member 20 .

[0059] When the anti-collision member 20 is in the first state, the contact 12 may be in the trigger position. At this time, the position detector 10 is triggered and sends a collision signal. The movable structure may stop moving according to the collision signal to reduce damage caused by the collision.

[0060] When the anti-collision member 20 is in the second state, the contact 12 may be located at the standby position. At this time, the anti-collision member 20 does not collide with an obstacle and the position detector 10 is not triggered.

[0061] The distance that the anti-collision component 20 moves from the second state to the first state may be L1, and the distance between the standby position and the trigger position may be L2, where L2 = L1.

[0062] The adjustment assembly 30 can adjust the size of L2, thereby adjusting the size of L1. In other words, the adjustment assembly 30 can adjust the travel of the contact 12 from the standby position to the trigger position, thereby adjusting the collision travel of the anti-collision member 20 corresponding to the trigger position detector 10.

[0063] Specifically, if it is necessary to shorten the collision stroke of the anti-collision member 20, when the anti-collision member 20 is in the second state, the original stroke corresponding to the contact 12 moving from the standby position to the trigger position is 5 mm, and the adjustment component 30 can pre-compress the contact 12 for a certain distance. For example, the adjustment component 30 can compress the contact 12 by 2 mm, change the standby position of the contact 12, and make the stroke corresponding to the contact 12 moving from the standby position to the trigger position become 3 mm. Therefore, when the anti-collision member 20 moves 3 mm after the collision, it can push the contact 12 to trigger the position sensor, so that the position sensor sends a collision signal, which is equivalent to improving the detection accuracy of the position detector 10 and shortening the displacement of the anti-collision member 20 required to generate collision feedback.

[0064] Therefore, according to the detection mechanism 100 of the embodiment of the present application, by setting an adjustment component 30 between the anti-collision part 20 and the position detector 10, the distance between the trigger position and the standby position of the contact 12 in the position detector 10 can be adjusted, that is, the stroke required for the contact 12 to trigger the position detector 10 to send a collision signal is adjusted, thereby adjusting the displacement of the anti-collision part 20 corresponding to the collision feedback generated by the detection mechanism 100. Therefore, the displacement can be shortened as needed to improve the detection accuracy of the position detector 10, making the collision detection of the detection mechanism 100 more sensitive, and accelerating the speed of the collision response to reduce the harm of the collision.

[0065] In some optional embodiments, the adjustment component 30 can be a telescopic rod extending along the first direction, and the telescopic rod can be driven by a driving member 400 such as a cylinder to adjust the position of the contact 12 when the anti-collision member 20 is in the second state as needed.

[0066] According to other embodiments of the present application, the detection mechanism 100 further includes: a fixing member 41, an extension rod 42, and a first elastic member 43. The fixing member 41 is fixed relative to the position detector 10. The extension rod 42 extends along a first direction, a first end of the extension rod 42 is connected to the anti-collision member 20, and a second end of the extension rod 42 is connected to the adjustment assembly 30. The first elastic member 43 is retractable in the first direction and is connected between the anti-collision member 20 and the fixing member 41.

[0067] Specifically, the fixing member 41 can be fixedly mounted on the movable structure, and the relative position between the fixing member 41 and the position detector 10 can be fixed. The extension rod 42 can extend along a first direction. In the first direction, the first end of the extension rod 42 can be away from the position detector 10 and connected to the anti-collision member 20, and the extension rod 42 can move synchronously with the anti-collision member 20. The second end of the extension rod 42 can be close to the position detector 10 and connected to the adjustment assembly 30, so that the adjustment assembly 30 and the anti-collision member 20 can move synchronously.

[0068] A first elastic member 43 may be connected between the fixing member 41 and the anti-collision member 20. The first elastic member 43 can be extended and retracted in a first direction. When the anti-collision member 20 collides with an obstacle, driving the extension rod 42 to move in the first direction toward the position detector 10, the anti-collision member 20 can compress the first elastic member 43. When the anti-collision member 20 separates from the obstacle, the elastic force of the first elastic member 43 can reset the anti-collision member 20, causing the anti-collision member 20 to move from the first state to the second state.

[0069] Optionally, the first elastic member 43 can be a spring, which can be mounted on the extension rod 42. The end of the first elastic member 43 close to the anti-collision member 20 can be connected to the anti-collision member 20, and the end of the first elastic member 43 away from the anti-collision member 20 can be connected to an end face of the fixing member 41 facing the anti-collision member 20.

[0070] In this embodiment, the fixing member 41 cooperates with the first elastic member 43 to transform the rigid collision of the anti-collision member 20 into a flexible collision, thereby reducing the impact force generated by the collision and minimizing the damage caused by the collision. In addition, the first elastic member 43 can also automatically reset the anti-collision member 20 after the collision.

[0071] In some specific embodiments of the present application, the adjustment assembly 30 includes: an adjustment member, a push rod 32, and a second elastic member 33. The adjustment member is connected to the second end of the extension rod 42, and the adjustment member is movable relative to the extension rod 42 along a first direction, and a first limiting portion 311 is provided on the adjustment member. The push rod 32 extends along the first direction, and one end of the push rod 32 away from the anti-collision member 20 abuts against the contact 12. A first matching portion 321 is provided on the push rod 32, and the first matching portion 321 is located on the side of the first limiting portion 311 close to the anti-collision member 20. The second elastic member 33 is retractable in the first direction, and the first end of the second elastic member 33 abuts against the extension rod 42, and the second end of the second elastic member 33 abuts against the push rod 32, and presses the first matching portion 321 against the first limiting portion 311.

[0072] Specifically, the adjustment assembly 30 in this embodiment may be mainly composed of an adjustment member, a push rod 32 and a second elastic member 33 .

[0073] The adjusting member may be connected to an end of the extension rod 42 away from the anti-collision member 20 , and the adjusting member may be movable along a first direction, thereby changing the distance between the adjusting member and the anti-collision member 20 .

[0074] The push rod 32 can extend along the first direction. In the first direction, the end of the push rod 32 away from the anti-collision member 20 can abut against the contact 12, so that when the push rod 32 moves along the first direction toward the position detector 10, it can push the contact 12 to trigger the position detector 10.

[0075] The end of the push rod 32 near the anti-collision member 20 can be movably connected to the adjustment member. Specifically, the adjustment member can be provided with a first limiting portion 311, and the push rod 32 can be provided with a first matching portion 321. In the first direction, the first matching portion 321 can be located on the side of the first limiting portion 311 near the anti-collision member 20, and the first limiting portion 311 can limit the push rod 32 through the first matching portion 321.

[0076] For ease of description, the positive direction of the first direction may be defined as the direction from the anti-collision member 20 toward the position detector 10 , and the negative direction of the first direction may be defined as the direction from the position detector 10 toward the anti-collision member 20 .

[0077] A second elastic member 33 is connected between the push rod 32 and the extension rod 42. The second elastic member 33 can extend and retract in the first direction. The two ends of the second elastic member 33 abut the extension rod 42 and the push rod 32, respectively. The extension rod 42 and the push rod 32 are each subjected to the elastic force of the second elastic member 33. Under the elastic force of the second elastic member 33, the first engaging portion 321 can press against the first limiting portion 311, preventing the push rod 32 from further moving in the first direction.

[0078] Since the adjusting member is movable along the first direction relative to the extension rod 42, and under the action of the second elastic member 33, the first matching portion 321 on the top rod 32 is always pressed against the first limiting portion 311. Therefore, the relative position of the top rod 32 and the adjusting member is fixed. The adjusting member can adjust the position of the top rod 32 relative to the anti-collision member 20 by adjusting its own position, thereby driving the top rod 32 to pre-press the contact 12.

[0079] For example, when it is necessary to shorten the displacement of the anti-collision member 20 required to generate collision feedback from 5mm to 3mm, the adjusting member can be moved 2mm in the direction away from the anti-collision member 20, thereby driving the second elastic member 33 and the top rod 32 to move 2mm in the direction away from the anti-collision member 20, so that the top rod 32 pre-compresses the contact 12 by 2mm. Therefore, when the anti-collision member 20 collides, the anti-collision member 20 moves 3mm to make the contact 12 in the trigger position.

[0080] In some optional embodiments, the push rod 32 and the adjusting member can be arranged to be spaced apart along the radial direction of the push rod 32, the first limiting portion 311 can be a protrusion on the adjusting member protruding toward the push rod 32, and the first matching portion 321 can be a protrusion on the push rod 32 protruding toward the adjusting member, and the two protrusions can abut against each other in the first direction.

[0081] According to some optional embodiments of the present application, the adjusting member includes a sleeve 31 and a nut 34. The sleeve 31 extends in a first direction. The first end of the sleeve 31 is sleeved over the second end of the extension rod 42 and threadedly connected to the extension rod 42. The end of the push rod 32, which is adjacent to the anti-collision member 20, extends into the second end of the sleeve 31. A first limiting portion 311 is provided on the inner wall surface of the sleeve 31 and protrudes into the sleeve 31. A first matching portion 321 is provided on the outer circumference of the push rod 32 and protrudes outward. The second elastic member 33 is provided in the sleeve 31. The nut 34 is threadedly connected to the extension rod 42 and is located on the side of the sleeve 31 away from the contact 12 to limit the position of the sleeve 31.

[0082] Specifically, the adjustment member may be primarily composed of a sleeve 31 and a nut 34. The outer surface of the extension rod 42 may be provided with external threads, and the sleeve 31 and nut 34 may be provided with internal threads. The sleeve 31 and nut 34 may be respectively threadedly connected to the second end of the extension rod 42, and the nut 34 may be located on the side of the sleeve 31 closest to the anti-collision member 20. By rotating the sleeve 31 or the nut 34, the sleeve 31 or the nut 34 can be moved along the extension rod 42 to adjust the position of the sleeve 31 and the nut 34. The nut 34 can limit the position of the sleeve 31 in the first direction to lock the sleeve 31.

[0083] In addition, the sleeve 31 has a hollow structure, and the end of the push rod 32 closest to the anti-collision member 20 can extend into the hollow structure of the sleeve 31, and the second elastic member 33 can also be accommodated in the sleeve 31. The inner wall surface of the sleeve 31 can be provided with an inwardly protruding first limiting portion 311, and the outer surface of the push rod 32 can be provided with an outwardly protruding first matching portion 321. The first limiting portion 311 can be a limiting step, and the first matching portion 321 can have a matching surface that can abut the step surface of the limiting step to limit the push rod 32 in the positive direction of the first direction.

[0084] In this embodiment, since the sleeve 31 and the nut 34 are respectively threadedly connected to the extension rod 42, the position of the sleeve 31 on the extension rod 42 can be adjusted by rotating the sleeve 31 and the nut 34, thereby utilizing the elastic force of the second elastic member 33 on the top rod 32 and the limiting force of the first limiting portion 311 on the first matching portion 321 to adjust the position of the top rod 32 relative to the extension rod 42, so that the top rod 32 can pre-compress the contact 12, thereby adjusting the collision stroke of the anti-collision member 20.

[0085] In addition, the provision of the second elastic member 33 can change the rigid contact between the top rod 32 and the contact 12 into a flexible contact, reducing the impact, making the collision process of the detection mechanism 100 smoother and more relaxed, and helping to reduce the damage caused by the collision.

[0086] Optionally, the second end of the extension rod 42 can be provided with an extension rod, the diameter of the extension rod can be smaller than the diameter of the second end of the extension rod 42, a channel can be provided in the top rod 32, the channel can pass through the top rod 32 along the first direction, a step can be provided in the channel, the second elastic member 33 can be a spring, the end of the spring close to the anti-collision member 20 can be sleeved on the extension rod, and the end of the spring away from the anti-collision member 20 can be extended into the channel of the top rod 32 and abut against the step, so that the spring applies a positive force along the first direction to the top rod 32.

[0087] In some optional embodiments, the top rod 32, the extension rod 42 and the sleeve 31 may be coaxially arranged.

[0088] According to some other embodiments of the present application, a second limiting portion 411 is provided at one end of the fixing member 41 away from the anti-collision member 20, and a second matching portion 421 is provided on the extension rod 42. The second matching portion 421 is located on the side of the second limiting portion 411 away from the anti-collision member 20. When the anti-collision member 20 is in the first state, the second limiting portion 411 is separated from the second matching portion 421. When the anti-collision member 20 is in the second state, the second limiting portion 411 is in contact with the second matching portion 421.

[0089] Specifically, the fixing member 41 may be provided with a second limiting portion 411, which is located at an end of the fixing member 41 away from the anti-collision member 20. The extension rod 42 may be provided with a second matching portion 421 that matches the first limiting portion 311, and the first limiting portion 311 may be located on a side of the second matching portion 421 close to the anti-collision member 20, so as to limit the extension rod 42 in the opposite direction of the first square.

[0090] When the anti-collision member 20 does not collide with an obstacle, the first matching portion 321 of the anti-collision member 20 abuts against the first limiting portion 311 under the elastic force of the first elastic member 43 , and the anti-collision member 20 is in the second state.

[0091] When the anti-collision member 20 collides with an obstacle and moves to the first state, the first elastic member 43 is compressed, and the second limiting portion 411 and the second matching portion 421 can be spaced apart along the first direction.

[0092] In this embodiment, by cooperating with the second limiting portion 411 on the fixing member 41 and the second matching portion 421 on the extension rod 42, the position of the anti-collision member 20 when in the second state can be relatively fixed. That is, no matter how the adjusting component 30 moves, when the anti-collision member 20 is in the second state, the distance between the anti-collision member 20 and the fixing member 41 and the main body 200 of the position detector 10 is unchanged. Therefore, by adjusting the distance between the adjusting component 30 and the anti-collision member 20, the adjusting component 30 can pre-press the contact 12, thereby adjusting the collision stroke of the anti-collision member 20.

[0093] Optionally, a limiting groove may be provided on an end face of the fixing member 41 away from the anti-collision member 20, and the limiting groove may be recessed in a direction close to the anti-collision member 20, and the bottom surface of the limiting groove may be formed as a second limiting portion 411, and the first matching portion 321 may be an annular boss, and the annular boss may protrude radially outward along the extension rod 42, and a side surface of the annular boss close to the anti-collision member 20 may abut against the bottom surface of the limiting groove to limit the extension rod 42 in the opposite direction of the first direction.

[0094] In some specific embodiments of the present application, the fixing member 41 is a linear bearing, which is sleeved on the extension rod 42. Thus, the extension rod 42 can move along the axis of the linear bearing, which is beneficial to reducing the friction between the extension rod 42 and the fixing member 41, making the collision feedback more sensitive.

[0095] According to some optional embodiments of the present application, the position detector 10 is a wireless limit switch. The contact 12 of the wireless limit switch can extend from the body of the wireless limit switch and abut against the push rod 32. The push rod 32 can pre-press the contact 12 so that a portion of the contact 12 is pressed into the wireless limit switch when the anti-collision member 20 is not hit.

[0096] In addition, the wireless limit switch can transmit a collision signal wirelessly, eliminating the need for cables connecting the limit switch. However, since the wireless limit switch moves along with the movable structure during movement, the cable also moves with it, shortening its service life. The wireless limit switch in this embodiment eliminates the need for cables, addressing cable life issues.

[0097] The embodiment of the present application further provides a stacker, which includes a main body 200, a supporting member 300, a driving member 400, and a detection mechanism 100. The supporting member 300 is movably provided on the main body 200 along a first direction, and the supporting member 300 is used to support the member to be supported 600. The driving member 400 is connected to the supporting member 300 and drives the supporting member 300 to move along the first direction. The detection mechanism 100 is the detection mechanism 100 according to any of the above embodiments, the position detector 10 is provided on the supporting member 300, and in the first direction, the anti-collision member 20 protrudes from the supporting member 300.

[0098] Specifically, the stacker can be set in a warehouse, which can accommodate shelves. The supported parts 600 can be goods. The stacker can take goods from the shelves or transport goods to the shelves for storage. The shelves in the warehouse can be used to store batteries, and the stacker can access the batteries.

[0099] The main body 200 of the stacker can move between shelves. The supporting member 300 is movably connected to the main body 200 to deliver goods to the shelves or remove goods from the shelves. The driving member 400 can be disposed on the main body 200 and connected to the supporting member 300 to drive the supporting member 300 to move in a first direction. Optionally, the driving member 400 can be a drive motor.

[0100] The detection mechanism 100 may be disposed on the supporting member 300 . Specifically, the position detector 10 and the fixing member 41 may be fixedly connected to the supporting member 300 , and the anti-collision member 20 may protrude from the supporting member 300 in the first direction.

[0101] For ease of explanation, the end of the support member 300 closer to the shelf to be accessed in the first direction can be defined as the front end of the support member 300, and the end farther from the shelf to be accessed can be defined as the rear end of the support member 300. The anti-collision member 20 can protrude from the front end or the rear end of the support member 300, or can protrude from both the front end and the rear end of the support member 300, without limitation herein.

[0102] Thus, when the supporting member 300 moves in the first direction, the anti-collision member 20 on the detection mechanism 100 can contact an obstacle before the supporting member 300 and the goods on the supporting member 300. The obstacle can be a shelf, goods on the shelf, or items related thereto. Under the influence of the obstacle, the anti-collision member 20 moves from the second state to the first state, triggering the position detector 10 to send a collision signal. The driving member 400 can then stop driving the supporting member 300 based on the collision signal, causing the supporting member 300 to stop moving. This achieves the purpose of stopping the supporting member 300 before it hits the obstacle, thereby protecting the obstacle and the stacker and preventing damage caused by the goods on the shelf from falling.

[0103] Since the detection mechanism 100 according to the embodiment of the present application has the above-mentioned technical effects, the stacker according to the embodiment of the present application also has corresponding technical effects, that is, the displacement of the anti-collision part 20 corresponding to the collision feedback generated by the detection mechanism 100 can be adjusted, and the displacement can be shortened according to needs to improve the detection accuracy of the position detector 10, so that the collision detection of the detection mechanism 100 is more sensitive, and the speed of the collision response is accelerated to reduce the harm of the collision.

[0104] According to some other embodiments of the present application, the anti-collision member 20 is an anti-collision plate, and the projection of the anti-collision plate along the first direction covers the projection of the supporting member 300 along the first direction.

[0105] For the sake of convenience, a projection surface can be defined, which can be perpendicular to the first direction. The projection of the anti-collision plate along the first direction on the above-mentioned projection surface can cover the projection of the supporting member 300 along the first direction on the projection surface. Thus, the anti-collision plate can fully protect the front end and / or rear end of the supporting member 300, ensuring that the anti-collision plate can collide with the obstacle before the supporting member 300, and trigger the wireless limit switch to send a collision signal during the process of the anti-collision plate being hit, ensuring that the supporting member 300 stops moving before contacting the obstacle, thereby achieving the purpose of protecting the obstacle.

[0106] In addition, the anti-collision plate may be spaced apart from the supporting member 300 in the first direction to reserve space for displacement of the anti-collision plate due to collision.

[0107] In some specific embodiments of the present application, the anti-collision plate is recessed toward the support member 300 and forms an avoidance groove 21. Thus, certain structures on the shelf can be avoided through the avoidance groove 21. For example, the shelf may be equipped with an auxiliary sensor for assisting transportation, and the avoidance groove 21 can avoid the auxiliary sensor to prevent the anti-collision plate from colliding with the auxiliary sensor and damaging the auxiliary sensor.

[0108] In some specific embodiments, the avoidance groove 21 may be a U-shaped groove, and the U-shaped groove may be symmetrically arranged on the anti-collision plate.

[0109] According to some optional embodiments of the present application, there are two detection mechanisms 100 , and the two detection mechanisms 100 are respectively disposed at two ends of the supporting member 300 in the first direction.

[0110] Specifically, one of the two detection mechanisms 100 can be disposed at the front end of the support member 300, and the other of the two detection mechanisms 100 can be disposed at the rear end of the support member 300. Therefore, the front end and the rear end of the support member 300 are respectively provided with anti-collision plates, and the two anti-collision plates can be spaced apart from the front end and the rear end of the support member 300, respectively.

[0111] Thus, the two detection mechanisms 100 can respectively play an anti-collision role when the supporting member 300 extends out of the main body 200 or retracts into the main body 200 along the first direction, and provide anti-collision protection for the shelves in front of and behind the supporting member 300.

[0112] According to some other embodiments of the present application, the supporting member 300 includes two fork arms 301, which extend respectively along a first direction and are spaced apart in a second direction, where the second direction intersects with the first direction. The position detector 10 is provided on one of the two fork arms 301, and a guiding mechanism 700 is provided on the other of the two fork arms 301 for guiding the anti-collision member 20 to move along the first direction.

[0113] Specifically, the support member 300 may be mainly composed of two fork arms 301. Each fork arm 301 may be a rod-shaped structure, and each fork arm 301 may extend along a first direction. The two fork arms 301 may be spaced apart along a second direction. Optionally, the second direction may be perpendicular to the first direction.

[0114] A detection mechanism 100 may be provided on one of the two fork arms 301 , and a guide mechanism 700 may be provided on one of the two fork arms 301 . The guide mechanism 700 may be connected to the anti-collision member 20 and guide the anti-collision member 20 to move along the first direction.

[0115] In some specific embodiments, the guide mechanism 700 may include a linear bearing, a guide rod, and a third elastic member. The linear bearing may be fixed to the fork arm 301. One end of the guide rod may be connected to the anti-collision member 20, and the other end of the guide rod may extend into the linear bearing. The guide rod is movable in a first direction. The third elastic member may be connected between the anti-collision member 20 and the linear bearing of the guide mechanism 700.

[0116] When the anti-collision member 20 is impacted, it will move, pushing the extension rod 42 and the guide rod along the corresponding linear bearings. The linear bearings guide the extension rod 42 and the guide rod, ensuring that the anti-collision member 20 moves in the first direction as a whole, preventing shaking of the anti-collision member 20 from affecting the triggering of the collision signal.

[0117] In some specific embodiments of the present application, the stacker further includes: a wireless receiver 500, which is wirelessly connected to the position detector 10 to receive the collision signal, and the wireless receiver 500 is electrically connected to the driving member 400 and controls the driving member 400 according to the collision signal.

[0118] Specifically, the wireless receiver 500 can cooperate with the wireless limit switch. When the wireless limit switch is triggered, the wireless limit switch can send a collision signal to the wireless receiver 500 through wireless transmission. Then, after receiving the collision signal, the wireless receiver 500 can control the driving part 400 to stop working, thereby stopping the supporting part 300 from moving, avoiding the supporting part 300 colliding with the obstacle and causing damage to the obstacle.

[0119] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
