[0036] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0037] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0038] All terms used herein, including technical and scientific terms, have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0039] When using expressions such as "at least one of A, B, and C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, and C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C. Similarly, when using expressions such as "at least one of A, B, or C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, or C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C.

[0040] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference to the directions in the accompanying drawings and are not intended to limit the scope of protection of this disclosure. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this disclosure.

[0041] Handling robots can transfer items between designated locations and buffer supports. They are typically equipped with limiting devices to prevent items from moving relative to the robot. These devices restrain the items during transfer, improving stability. However, handling robots can only handle and transfer items of fixed sizes, limiting their ability to handle other sizes. This results in limited applicability and flexibility for handling robots.

[0042] Embodiments of this disclosure provide a transfer device, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transfer device includes a carrying mechanism 1 and a limiting mechanism 2. The carrying mechanism 1 is configured to carry an item 6 and has a first state of moving on a working surface and a second state of moving up and down in the vertical direction to store the item 6 into or remove the item 6 from the buffer rack 7. The limiting mechanism 2 is adjustablely disposed on the carrying mechanism 1 to cooperate with the item 6 and, in the first state, prevents the item 6 from moving relative to the carrying mechanism 1.

[0043] It should be noted that, referring to Figure 1 As shown, a buffer rack 7 is installed on a storage rack 8 for temporarily buffering items 6. The storage rack 8 has multiple storage slots 81 for placing items 6. A retrieval robot (not shown in the figure) is slidably mounted on the storage rack 8, which can transfer items 6 between the storage slots 81 and the buffer rack 7.

[0044] In use, the buffer rack 7 receives items 6 stored in by the transfer equipment, allowing the retrieval robot to retrieve items 6 from the buffer rack 7 and transfer them to the designated storage location 81 of the storage rack 8. Alternatively, the retrieval robot retrieves items 6 from storage location 81 and stores them in the buffer rack 7. The buffer rack 7 temporarily stores items 6, allowing the transfer equipment to retrieve the temporarily stored items 6 from the buffer rack 7 and transfer them to the designated location.

[0045] Furthermore, the working surface is horizontally positioned. The working surface can be the ground, a transfer platform, etc., allowing the carrying mechanism 1 to move on the working surface to transfer items 6 between a designated location and the buffer support 7. The carrying mechanism 1 moves on the working surface via, but is not limited to, wheels, traction components, conveying components, slide rails and sliding components, or any other moving mechanism. The carrying mechanism 1 also includes, but is not limited to, scissor lifts, lead screws and sliders, gears and racks, or any other lifting mechanism to move vertically.

[0046] The carrying mechanism 1 is configured to carry items and can move horizontally on the working surface and rise and fall vertically, thus having both lifting and lowering states. Specifically, during the transfer of items 6 on the working surface, the carrying mechanism 1 is generally in the lowering state and moves horizontally at high speed on the working surface. During the process of placing items 6 on or removing items 6 from the buffer support 7, the carrying mechanism 1 generally moves horizontally at low speed on the working surface.

[0047] In detail, refer to Figure 1 As shown, the supporting mechanism 1 carries the item 6 and moves horizontally to the vicinity of the buffer support 7. Then, the supporting mechanism 1 rises to face the buffer support 7. The supporting mechanism 1 moves towards the buffer support 7. Figure 1 The mechanism moves horizontally (from left to right) so that the buffer holder 7 is inserted between the item 6 and the support mechanism 1. Then, the support mechanism 1 lowers, placing the item 6 on the buffer holder 7 to store it. Conversely, the support mechanism 1 moves below the buffer holder 7 and rises to lift the item 6 from the buffer holder 7, detaching it from the buffer holder 7. Then, the support mechanism 1 moves horizontally away from the buffer holder 7 to remove the item 6 from it.

[0048] The first state represents the horizontal movement of the bearing mechanism 1 on the working surface. The second state represents the vertical movement of the bearing mechanism 1. It can be understood that the first state of the bearing mechanism 1 moving horizontally on the working surface and the second state of vertical movement can occur independently or simultaneously.

[0049] The limiting mechanism 2 is adjustablely mounted on the carrying mechanism 1 through various means, including but not limited to bolts and threaded holes, snap-fit ​​connections, telescopic components, slide rails and positioning elements, or other installation methods. This allows the limiting mechanism 2 to be adjusted according to the size of the item 6, enabling it to cooperate with items 6 of different sizes. Thus, when the carrying mechanism 1 is in its first moving state on the working surface, the limiting mechanism 2 prevents the item 6 from moving relative to the carrying mechanism 1, thereby stabilizing the transfer of the item 6. By providing an adjustable limiting mechanism 2, it is suitable for items 6 of different sizes, limiting and transferring items 6 of varying sizes, thus improving the applicability and flexibility of the transfer equipment.

[0050] In one exemplary embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, the supporting mechanism 1 includes a drive mechanism 11 and a supporting assembly 12. The drive mechanism 11 is configured to have a first state of moving on the working surface and a second state of moving up and down in the vertical direction. The supporting assembly 12 is disposed on the drive mechanism 11 to support the article 6.

[0051] Specifically, the support assembly 12 is provided with a support surface for supporting the item 6, providing upward support for the item 6. The support surface is approximately parallel to the working surface and also approximately parallel to the horizontal plane. In the first state, the drive mechanism 11 drives the support assembly 12 and the item 6 to move horizontally on the working surface, and the limiting mechanism 2 limits the item 6 to prevent it from moving relative to the support assembly 12, thereby improving the stability of the item 6 transfer. In the second state, the drive mechanism 11 moves vertically to adjust the height of the item 6, thereby storing the item 6 in or retrieving it from the buffer bracket 7.

[0052] In one exemplary embodiment, reference is made to Figure 3 and Figure 4 As shown, the drive mechanism 11 includes a moving component 111 and a lifting component 112. The moving component 111 is configured to move on the working surface. The lifting component 112 is disposed on the moving component 111 and configured to move vertically. The bearing component 12 is disposed on the lifting component 112.

[0053] In detail, the moving component 111 may be a combination of a traveling wheel, a conveying component, a slide rail, and a sliding component, etc., which is not limited here, to move on the working surface and be in a first state. In this embodiment, the moving component 111 includes, but is not limited to, the traveling wheel, which rolls on the working surface through a motor or other driving components, thereby driving the lifting component 112 and the carrying component 12 to move on the working surface.

[0054] The lifting assembly 112 can be a scissor linkage mechanism, a scissor lift platform, a lead screw and slider mechanism, a gear and rack mechanism, etc., and is not limited here, to adjust the height of the carrying assembly 12 and the item 6. The lifting assembly 112 includes, but is not limited to, a scissor linkage mechanism and a driving component. The scissor linkage mechanism includes at least two sets of links rotatably connected by a rotating shaft to form a scissor structure. The driving component includes, but is not limited to, a motor and a lead screw. The motor is located in the scissor linkage mechanism. The lead screw is connected to the output end of the motor to rotate under the drive of the motor. The lead screw is threadedly connected to the two links at the top of the scissor linkage mechanism, and the threads rotate in opposite directions. Rotation of the lead screw drives the two sets of links at the top of the scissor linkage mechanism to move closer together, thereby raising the scissor linkage mechanism. Conversely, rotation of the lead screw drives the two sets of links at the top of the scissor linkage mechanism to move away from each other, thereby lowering the scissor linkage mechanism. By setting the lifting assembly 112, the height position of the carrying assembly 12 and the item 6 can be adjusted.

[0055] In one exemplary embodiment, reference is made to Figure 4 As shown, the moving assembly 111 includes a chassis assembly 1111 and a moving part 1112. The chassis assembly 1111 includes two chassis that are hinged to each other. The moving part 1112 is rotatably disposed on the chassis assembly 1111 to move on the working surface.

[0056] In detail, the two chassis are hinged to each other by means of, but not limited to, pivots, hinges, universal joints, or any other hinged assembly. The moving part 1112 may be a wheel, sprocket, etc., and is not limited thereto. The wheel rolls on the working surface by means of a motor or other drive unit, thereby driving the lifting assembly 112 and the load-bearing assembly 12 to move on the working surface.

[0057] In this implementation, the two chassis are hinged together, allowing them to swing relative to each other. This enables movement on uneven working surfaces, reducing the bumps and jolting of the transport equipment while transferring the items 6, and improving the stability of the transport of the items 6.

[0058] In one exemplary embodiment, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the supporting assembly 12 includes a supporting portion 121 and a supporting assembly 122. The supporting portion 121 is disposed on top of the lifting assembly 112. The supporting assembly 122 is disposed on the supporting portion 121, forming a clearance groove 1222 with an open top. The item 6 is placed on top of the supporting assembly 122. In a first state, the clearance groove 1222 allows the buffer support 7 to be inserted or removed horizontally. In a second state, the drive mechanism 11 descends, causing the buffer support 7 to move out of the opening of the clearance groove 1222 and support the item 6; or the drive mechanism 11 rises, causing the top of the supporting assembly 122 to be higher than the buffer support 7 to support the item 6.

[0059] It should be noted that, referring to Figure 1 and Figure 2 As shown, the buffer bracket 7 includes multiple supports spaced apart in the horizontal direction. Specifically, the multiple supports are all in the first direction ( Figure 1 Extending in the lateral direction, multiple struts extend in the second direction (in the middle direction). Figure 2 The second direction and the first direction are distributed at intervals along the horizontal direction. Both directions are parallel to the horizontal plane and perpendicular to each other.

[0060] Furthermore, a support component 122 is disposed on the top surface of the support portion 121, and the top end of the support component 122 forms a support surface for supporting the article 6. (See reference...) Figure 2 As shown, the top of the support component 122 contacts the bottom surface of the item 6 and provides an upward supporting force to the item 6. The support component 122 forms a plurality of clearance slots 1222, which cooperate with a plurality of support rods of the buffer bracket 7, so that the support rods of the buffer bracket 7 can be inserted into or removed from the corresponding clearance slots 1222 in the horizontal direction.

[0061] According to embodiments of this disclosure, referring to Figure 1 and Figure 2 As shown, during the process of storing the item 6 carried on the carrying component 12 into the buffer bracket 7, the lifting component 112 drives the carrying component 12 to move vertically, thereby adjusting the height of the support component 122 so that the multiple clearance slots 1222 formed by the support component 122 are at the same height and opposite to the multiple support rods of the buffer bracket 7. Then, the moving component 111 drives the carrying component 12 towards the direction closer to the buffer bracket 7. Figure 1 Move to the right (from center) so that the support rod inserts into the clearance slot 1222 (as shown in the image). Figure 2 (As shown). At this time, item 6 is located above the cache holder 7. Subsequently, the lifting assembly 112 drives the bearing assembly 12 and the support assembly 122 to descend, causing the support rod to move out from the top of the clearance slot 1222 to support item 6, thereby completing the storage of item 6 in the cache holder 7.

[0062] During the process of the transfer device retrieving item 6 from the buffer bracket 7, the drive mechanism 11 drives the support component 122 of the carrying assembly 12 to form a clearance groove 1222 to accommodate the support rod of the buffer bracket 7. Next, the lifting assembly 112 drives the support component 122 to move upwards, so that the top of the support component 122 is higher than the height of the support rod of the buffer bracket 7, thus supporting item 6 and separating the bottom surface of item 6 from the support rod. Subsequently, the moving assembly 111 drives the carrying assembly 12 to move away from the buffer bracket 7 (…). Figure 1 Move from the center to the left to remove item 6 from the buffer holder 7.

[0063] In one exemplary embodiment, reference is made to Figure 6 As shown, the support assembly 122 includes at least two sets of support portions 1221, which are detachably disposed on the bearing portion 121 and are spaced apart to form relief grooves 1222.

[0064] In detail, at least two sets of support sections 1221 are in the first direction ( Figure 1 Extending in the lateral direction of the buffer bracket 7 and spaced apart in the second direction, it forms a relief groove 1222 extending in the first direction to cooperate with the support rod of the buffer bracket 7.

[0065] It should be noted that the height of the support part 1221 is greater than the thickness of the support rod of the buffer bracket 7, so as to facilitate the storage and retrieval of item 6 from the buffer bracket 7. Multiple sets of support components 122 can be provided, such as three, four, five, etc., which are not limited here and are determined according to actual needs. The support part 1221 is detachably mounted on the bearing part 121 by means of bolts and threaded holes, snap-fit, magnetic attachment, or other installation methods.

[0066] Specifically, referring to Figure 6, the support portion 1221 is provided in two sets. One set of support portions 1221 includes two support plates extending in a first direction and spaced apart in a second direction. The other set of support portions 1221 includes a U-shaped support plate forming a clearance groove 1222 with an open top, which cooperates with the support rod. The U-shaped support plate is located between the two support plates. The distance between the U-shaped support plate and the two support plates is limited by the support rod of the buffer bracket 7, thereby forming a clearance groove 1222 that cooperates with the support rod of the buffer bracket 7. The bearing portion 121 is provided with multiple threaded holes for bolts to be threaded through the support portion 1221 and threaded into the threaded holes to install the support portion 1221 onto the bearing portion 121. The support portion 1221 is easy to disassemble and replace, and at the same time reduces maintenance costs.

[0067] In one exemplary embodiment, reference is made to Figure 6 As shown, a weight-reducing hole is provided on the support part 1221. The weight-reducing hole penetrates the support part 1221 to reduce the weight of the support part 1221, thereby reducing the overall weight of the transfer equipment and thus reducing the load on the drive mechanism 11.

[0068] In one exemplary embodiment, reference is made to Figure 6 , Figure 7 and Figure 8As shown, the limiting mechanism 2 includes a first limiting component 21 and a second limiting component. The first limiting component 21 prevents the article 6 from moving relative to the carrying mechanism 1 in a first direction. The second limiting component 22 prevents the article 6 from moving relative to the carrying mechanism 1 in a second direction, wherein the second direction intersects with the first direction. It can be understood that the limiting mechanism 2 may include only the first limiting component 21 or the second limiting component 22.

[0069] It should be noted that the first direction ( Figure 7 The lateral direction (in the text) refers to the extension direction of the support rod of the buffer bracket 7. The second direction refers to the direction in which the angle between the horizontal plane and the first direction is 90 degrees. It can be understood that the angle between the second direction and the first direction can also be 80 degrees, 70 degrees, 60 degrees, 50 degrees, etc., as long as it prevents the item 6 from moving relative to the supporting mechanism 1 in the first state.

[0070] In detail, the first limiting component 21 and the second limiting component 22 can be a limiting plate, a clamping component, a pressing component, a robot, a fixture, etc., and the specific limitations are determined according to actual needs.

[0071] According to embodiments of this disclosure, when the carrying mechanism 1 is in its first state and moving horizontally at a relatively high speed while carrying the article 6 on the working surface, the article 6 is prone to displacement due to bumps, or displacement or slippage from the carrying mechanism 1 under the action of inertial force. The first limiting component 21 and the second limiting component 22 prevent the article 6 from moving relative to the carrying mechanism 1, thereby improving the stability and safety of the transfer equipment for transferring the article 6.

[0072] In one exemplary embodiment, reference is made to Figure 6 , Figure 7 and Figure 8 As shown, the first limiting component 21 includes a first limiting part 211 and a second limiting part 212. The second limiting part 212 is adjustablely disposed on the support mechanism 1 and has a lowering state and a lifting state as the support mechanism 1 moves up and down in the vertical direction. Specifically, the second limiting part 212 is adjustablely disposed at one end of the support part 121 to move up and down in the vertical direction under the drive of the lifting component 112. The first limiting part 211 is disposed on the support mechanism 1 and is located at a second height lower than the first height of the buffer bracket 7. Specifically, the first limiting part 211 is opposite to the second limiting part 212 and is disposed on the chassis away from the second limiting part 212. Figure 8 (The chassis on the right side). The height of the first limiting part 211 is fixed and it is located at a second height that is lower than the first height of the buffer bracket 7.

[0073] The second limiting part 212 is adjustablely disposed on the bearing part 121 by means of bolts and threaded holes, snap-fit ​​connection, telescopic components or other connection methods to adjust the distance between the first limiting part 211 and the second limiting part 212.

[0074] Among them, reference Figure 1 and Figure 7 As shown, in the lifted state, the second limiting part 212 is higher than the second height, and the first limiting part 211 is located below the buffer bracket 7, so as to store the item 6 into or remove the item 6 from the buffer bracket 7. (Refer to...) Figure 8 As shown, in the lowering state, the second limiting part 212 and the first limiting part 211 limit the item 6 in a first direction to prevent the item 6 from sliding off the carrying mechanism 1. Specifically, the second limiting part 212 and the first limiting part 211 may contact the item 6 to prevent the item 6 from moving relative to the carrying mechanism 1, or at least one of the second limiting part 212 and the first limiting part 211 may have a gap with the item 6 to allow the item 6 to move slightly relative to the carrying mechanism 1, after which either the second limiting part 212 or the first limiting part 211 may contact the item 6 to prevent the item 6 from sliding off the carrying mechanism 1.

[0075] It should be noted that the first height refers to the height of the buffer bracket 7 relative to the working surface. The second height refers to the height of the first limiting part 211 relative to the working surface. The second height is lower than the first height.

[0076] In detail, refer to Figure 8 As shown, in the lowered state, both the second limiting part 212 and the first limiting part 211 are in contact with the item 6. The second limiting part 212 and the first limiting part 211 are located at the left and right ends of the item 6, respectively, to limit the item 6 in the first state, prevent the item 6 from moving left and right relative to the carrying component 12, and improve the stability of the item 6 transfer.

[0077] According to an embodiment of this disclosure, in the lifted state, during the process of storing item 6 into the buffer bracket 7, the second limiting part 212 is raised under the drive of the lifting assembly 112 to a height higher than the second height, so that the clearance groove 1222 of the supporting assembly 12 is opposite to the support rod of the buffer bracket 7. At this time, the first limiting part 211 separates from item 6, canceling its limiting effect on item 6. At the same time, the first limiting part 211 is located below the buffer bracket 7, thereby achieving clearance, allowing the support assembly 12 to insert the support rod of the buffer bracket 7 into the clearance groove 1222 of the supporting assembly 12 under the drive of the moving assembly 111. In this way, the first limiting part 211 will not interfere with the buffer bracket 7, thereby improving the convenience of storing item 6 into or retrieving item 6 from the buffer bracket 7.

[0078] In one exemplary embodiment, reference is made to Figure 6As shown, the second limiting part 212 is adjustablely disposed on the bearing part 121 of the bearing mechanism 1 and is configured to adjust the distance between the second limiting part 212 and the first limiting part 211 to accommodate articles 6 of different sizes in the first direction.

[0079] In detail, refer to Figure 6 As shown, the support portion 121 has a plurality of threaded holes spaced apart in the first direction. The second limiting portion 212 is adjustablely mounted on the support portion 121 by means of bolts threadedly engaging with the threaded holes on the support portion 121.

[0080] In this embodiment, by adjusting the distance between the second limiting part 212 and the first limiting part 211, it can accommodate articles 6 of different sizes in the first direction and prevent the articles 6 from moving relative to the carrying mechanism 1 in the first direction, thereby improving the stability of the article 6 transfer. By providing an adjustable second limiting part 212 to limit and transfer articles 6 of different sizes, the applicability and flexibility of the transfer equipment are improved.

[0081] In one exemplary embodiment, reference is made to Figure 7 and Figure 8 As shown, both the first limiting part 211 and the second limiting part 212 include a connecting part 3 and a protrusion 4. The connecting part 3 is disposed on the supporting mechanism 1. The protrusion 4 is connected to the connecting part 3 to protrude upward and prevent the article 6 from sliding off the supporting mechanism 1. In the lowered state, the top surface of the connecting part 3 of the first limiting part 211 is spaced apart from the bottom surface of the article 6.

[0082] In detail, refer to Figure 7 and Figure 8 As shown, the connecting part 3 of the second limiting part 212 is disposed at one end of the bearing part 121. Figure 8 (Left end of the middle support part 121). In the lowered state, the top surface of the connecting part 3 of the first limiting part 211 is located below the bottom surface of the item 6 and is spaced apart from the bottom surface of the item 6. The connecting part 3 of the first limiting part 211 is located on the chassis away from the second limiting part 212 ( Figure 8 The chassis is located on the right side of the center.

[0083] According to an embodiment of this disclosure, when the transport device carrying the item 6 moves horizontally on the working surface, the first limiting part 211 is in a lowered state. The protrusions 4 of the first limiting part 211 and the second limiting part 212 protrude upwards, respectively contacting the left and right sides of the item 6, or having a gap between them to allow the item 6 to move slightly relative to the carrying part 121, thereby limiting the item 6 in the first direction, preventing the item 6 from slipping off the carrying part 121, and improving the stability of the transport of the item 6. Since the two chassis are hinged to each other, they will float relative to each other when the working surface is uneven. The top surface of the connecting part 3 of the first limiting part 211 is spaced apart from the bottom surface of the item 6, so that the connecting part 3 of the first limiting part 211 does not contact the item 6. During the relative floating of the two chassis, the connecting part 3 of the first limiting part 211 is prevented from constantly hitting the item 6, reducing the risk of the item 6 shaking or even falling, thereby stabilizing the transport of the item 6.

[0084] In one exemplary embodiment, reference is made to Figure 4 , Figure 5 and Figure 6 As shown, the second limiting component 22 includes at least two sets of side limiting portions 221 spaced apart in the second direction, such that the at least two sets of side limiting portions 221 are located on both sides of the article 6.

[0085] It should be noted that, referring to Figure 2 and Figure 5 As shown, at least two sets of side limiting parts 221 are spaced apart from the support assembly 122. The distance between each set of side limiting parts 221 and the support assembly 122 forms a clearance groove 1222 to cooperate with the support rod of the buffer bracket 7. Therefore, the distance between each set of side limiting parts 221 and the support assembly 122 is limited by the support rod. Multiple sets of side limiting parts 221 can be provided, for example, three, four, or five sets, etc., which are not limited here. Multiple sets of side limiting parts 221 are located on both sides of the item 6 to limit the movement of the item 6.

[0086] In detail, refer to Figure 5 As shown, in this embodiment, two sets of side limiting parts 221 are provided, and the two sets of side limiting parts 221 are in the second direction ( Figure 5 The two sets of side limiting parts 221 are spaced apart along the horizontal direction of the article 6, and are located at the left and right ends of the supporting part 121, respectively. Thus, the two sets of side limiting parts 221 are located on both sides of the article 6. Figure 4 (The front and back sides of item 6).

[0087] In this embodiment, at least two sets of side limiting portions 221 are respectively located on both sides of the article 6 to limit the article 6 in the first state, preventing the article 6 from moving relative to the carrier assembly 12 in the second direction, thereby further improving the stability of the article 6 during transport.

[0088] In one exemplary embodiment, reference is made to Figure 4 , Figure 5 and Figure 6 As shown, at least two sets of side limiting parts 221 are adjustablely disposed on the carrying mechanism 1 to adjust the distance between the side limiting parts 221 on both sides of the article 6, which is suitable for articles 6 of different sizes in the second direction.

[0089] In detail, refer to Figure 6 As shown, the support portion 121 has a plurality of threaded holes spaced apart in the second direction. The side limiting portion 221 is adjustablely mounted to the support portion 121 by means of bolts threadedly engaging with the threaded holes on the support portion 121.

[0090] In this embodiment, by adjusting the distance between the two side limiting parts 221, it can be adapted to articles 6 of different sizes in the second direction, thereby limiting and transferring articles 6 of different sizes, and improving the applicability and flexibility of the transfer equipment.

[0091] In one exemplary embodiment, reference is made to Figure 5 and Figure 6 As shown, the tops of the two sets of side limiting parts 221 are tilted in a direction away from each other to increase the distance between the tops of the two sets of side limiting parts 221, so that the item 6 can be placed between the two sets of side limiting parts 221 and the item 6 can be guided to be placed on the bearing surface of the top of at least two sets of support parts 1221.

[0092] In one exemplary embodiment, reference is made to Figure 9 and Figure 10 As shown, the drive mechanism 11 also includes a support shaft 113 and a proximity switch 114. The support shaft 113 is disposed on the lifting assembly 112 and moves up and down with the lifting assembly 112. The proximity switch 114 is disposed on the moving assembly 111 and is configured such that when the second limiting part 212 moves to the lowering state with the carrying mechanism 1, the support shaft 113 contacts the proximity switch 114 and controls the lifting assembly 112 to stop moving.

[0093] Specifically, the support shaft 113 is mounted on the lifting assembly 112 and moves up and down with it to indicate the position of the lifting assembly 112. A proximity switch 114 is mounted on the chassis assembly 1111. The proximity switch 114 includes, but is not limited to, Hall effect proximity switches, photoelectric proximity switches, etc. The proximity switch can also be a limit switch, a contact switch, etc. Thus, during the vertical movement of the lifting assembly 112, the support shaft 113 and the second limiting part 212 move up and down with the lifting assembly 112. When the second limiting part 212 moves to the lowered state, the proximity switch 114 contacts the support shaft 113 and controls the lifting assembly 112 to stop moving, thereby accurately positioning the lifting assembly 112.

[0094] It should be noted that when the lifting assembly 112 is a scissor lift, the scissor linkage mechanism of the scissor lift will deform under its own weight and the weight of the item 6 after the drive component of the scissor lift stops, causing it to continue to lower. This will result in inaccurate height control by the lifting assembly 112 and will also exacerbate damage to the lifting assembly 112 itself.

[0095] In this embodiment, the proximity switch 114 contacts the support shaft 113, so that the proximity switch 114 provides an upward support force to the support shaft 113, thereby supporting the lifting assembly 112, improving the positioning accuracy of the lifting assembly 112 and preventing excessive deformation.

[0096] In one exemplary embodiment, reference is made to Figure 5 , Figure 7 , Figure 11 and Figure 12 As shown, the transfer device also includes a contact frame 1121 and an assist component 5. The contact frame 1121 is disposed on the lifting assembly 112. The assist component 5 is elastically disposed on the bearing assembly 12 and is configured such that when the second limiting part 212 is in the lowered state, the assist component 5 contacts the contact frame 1121 and is compressed to provide an upward thrust to the scissor linkage mechanism of the lifting assembly 112.

[0097] In detail, the contact frame 1121 is disposed in the scissor linkage mechanism of the lifting assembly 112 and is located below the rotation axis of the scissor linkage mechanism.

[0098] The assist component 5 is located above the contact frame 1121. The assist component 5 can be a spring, rubber damper, air spring, hydraulic damper, etc., depending on actual needs. The extension and retraction direction of the assist component 5 is the same as the lifting direction of the lifting component 112, i.e., the vertical direction.

[0099] According to embodiments of this disclosure, when the lifting assembly 112 is in the lifting state, the assist component 5 separates from the contact frame 1121. During the continuous descent of the lifting assembly 112, the assist component 5 contacts the contact frame 1121 and is continuously compressed. Simultaneously, the assist component 5 provides an upward thrust to the lifting assembly 112. When the lifting assembly 112 switches from the lowering state to the lifting state, i.e., in the initial stage when the drive component of the lifting assembly 112 drives the scissor linkage mechanism to rise, the upward thrust of the assist component 5 on the lifting assembly 112 provides elastic assistance in lifting, which helps reduce the load on the drive component of the lifting assembly 112. This plays an important role in the lifting load of the lifting assembly 112 on the item 6, enabling the transfer equipment to adapt to scenarios involving the storage, retrieval, and handling of heavier items 6.

[0100] In one exemplary embodiment, reference is made to Figure 5 , Figure 7 , Figure 11 and Figure 12As shown, the assist component 5 includes an elastic member 51 and a guide portion 52. The elastic member 51 is elastically disposed below the support portion 121 and is configured to have a compressed state where it is compressed by the contact frame 1121 and a reset state where it is separated from the contact frame 1121 and extended. The guide portion 52 is vertically telescopingly disposed on the support portion 121 and located between adjacent support portions 1221 to guide the elastic member 51 to extend or compress. In the compressed state and the reset state, the top end of the guide portion 52 is lower than the top end of the support portion 1221.

[0101] In detail, the elastic element 51 is elastically disposed at the bottom of the support portion 121. The elastic element 51 can be a coil spring, compression spring, air bladder, etc., depending on the actual needs. The elastic element 51 is located above the contact frame 1121. The guide portion 52 is disposed on the support portion 121 and is vertically telescopically mounted on the support portion 121. The bottom end of the guide portion 52 is connected to the bottom end of the elastic element 51 so that during the adjustment process between the compressed state and the reset state of the elastic element 51, the guide portion 52 extends and retracts relative to the support portion 121, thereby guiding the elastic element 51 to extend or compress.

[0102] Specifically, refer to Figure 7 and Figure 11 As shown, the lifting assembly 112 raises the bearing assembly 12, causing the elastic element 51 to separate from the contact frame 1121, and the elastic element 51 is in a reset state. (Refer to...) Figure 5 and Figure 12 As shown, the elastic member 51 is compressed by the bearing portion 121 and the contact frame 1121, and is in a compressed state, generating an upward thrust on the bearing portion 121. At the same time, the top of the guide portion 52 is higher than the top surface of the bearing portion 121.

[0103] It should be noted that the guide portion 52 is located between adjacent support portions 1221, thereby making full use of the space between adjacent support portions 1221, improving space utilization, and reducing the volume of the transfer equipment. In the reset state or compressed state, the height of the top end of the guide portion 52 is lower than the height of the bearing surface formed by the top end of the support portion 1221, so as to avoid affecting the support assembly 122 bearing the item 6.

[0104] In one exemplary embodiment, reference is made to Figure 11 , Figure 12 and Figure 13 As shown, the assist component 5 also includes a mounting base 53, a limiting head 54, and a pressing head 55. The mounting base 53 is mounted on the support portion 121. The guide portion 52 is slidably mounted on the mounting base 53. The pressing head 55 is disposed at the first end of the guide portion 52. Figure 12 The bottom end of the guide section 52). An elastic element 51 is sleeved around the guide section 52 and positioned between the pressure head 55 and the mounting base 53. A limiting head 54 is located at the second end of the guide section 52. Figure 12The top of the guide section 52).

[0105] According to embodiments of this disclosure, referring to Figure 7 and Figure 11 As shown, the pressure head 55 separates from the contact frame 1121, and the elastic element 51 is in the reset state. At this time, the limiting head 54 contacts the bearing portion 121 and limits the guide portion 52 and the elastic element 51, maintaining them in the reset state. (Refer to...) Figure 5 and Figure 12 As shown, the pressure head 55 contacts the contact frame 1121 and compresses the elastic element 51, causing the elastic element 51 to be in a compressed state. At this time, the guide portion 52 moves upward relative to the bearing portion 121, and the limiting head 54 separates from the bearing portion 121. In this way, by fitting the elastic element 51 onto the guide portion 52, the guide portion 52 guides the elastic element 51 to extend or compress, preventing the elastic element 51 from bending or excessively deforming under high compressive force, thus affecting normal use.

[0106] According to the transfer equipment provided in this disclosure, the limiting mechanism 2 is adjusted according to the size of the item 6, so that the limiting mechanism 2 can cooperate with items 6 of different sizes. When transferring the item 6, the carrying mechanism 1 carries the item 6, and the limiting mechanism 2 can limit the items 6 of different sizes. Thus, when the carrying mechanism 1 is in the first state of moving on the working surface, the limiting mechanism 2 prevents the item 6 from moving relative to the carrying mechanism 1, thereby stabilizing the transfer of the item 6. The carrying mechanism 1 moves on the working surface and rises and falls vertically to store the item 6 into or remove the item 6 from the buffer holder 7. By setting the adjustable limiting mechanism 2, it is suitable for items 6 of different sizes, limiting and transferring items 6 of different sizes, thus improving the applicability and flexibility of the transfer equipment.
