Description

Technical Field

[0001] This utility model relates to the field of loading and unloading technology, and in particular to a loading and unloading mechanism and a loading and unloading vehicle. Background Technology

[0002] In logistics and manufacturing, conveyor belt systems are widely used for the automated transport of objects. As a key piece of equipment connecting different transport stages, the performance of the loading and unloading mechanism directly affects overall efficiency. Currently, most existing loading and unloading mechanisms use a combination of limit plates and moving suction cups, but this has significant drawbacks. During the conveyor belt transport process, objects need to be automatically grabbed and placed on the conveyor belt for transport. However, existing loading and unloading mechanisms typically only have two limit zones on the limit plates, which can only guarantee grabbing or avoidance. During movement, if the drive unit malfunctions, the moving plate will cause the object to collide rapidly with the object to be transferred, resulting in collisions and damage.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figure 1 This embodiment is the first embodiment of the utility model. This embodiment provides a loading and unloading mechanism, including a drive unit 101, a limiting plate 200, a moving plate 300 and a suction cup 400.

[0027] Specifically, the upper surface of the limiting plate 200 is provided with a limiting path 201, and a limiting area 202 is provided on the limiting path 201. In this embodiment, there are two limiting areas 202, which are located at the two ends of the limiting path 201 respectively.

[0028] Preferably, the movable plate 300 and the limiting plate 200 are arranged parallel to each other, the driving unit 101 is connected to the movable plate 300 in a transmission manner, the driving unit 101 can drive the movable plate 300 to move, wherein the projection of the movable plate 300 on the limiting plate 200 can move along the path direction of the limiting path 201, and the suction cup 400 is arranged on the movable plate 300, and the suction cup 400 moves synchronously with the movable plate 300.

[0029] Preferably, by moving the movable plate 300 to the left or right with a predetermined stroke, the projection of the movable plate 300 on the limiting plate 200 can coincide with the limiting areas 202 located at the left and right ends of the limiting path 201, so as to adjust the relative height between the suction cup 400 and the limiting plate 200.

[0030] When the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 located at the right end of the limiting path 201, the suction cup 400 picks up the object; and when the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 located at the left end of the limiting path 201, the suction cup 400 stores the object to avoid obstructing the transported object.

[0031] Example 2

[0032] Reference Figure 2 , Figure 3 and Figure 5 This embodiment is the second embodiment of the utility model, and this embodiment is based on embodiment 1.

[0033] This embodiment is basically the same as embodiment 1, except that the limiting path 201 in this embodiment is provided with five limiting areas 202. The limiting areas 202 are evenly arranged along the path direction of the limiting path 201. If the driving unit 101 fails, when the moving plate 300 drives the suction cup 400 to pick up the object and move it towards the object that has not yet been transferred, it will be slowed down by multiple limiting areas 202, thereby avoiding rapid collision between objects and damage.

[0034] Example 3

[0035] Reference Figures 1-4 This embodiment is the third embodiment of the utility model, and this embodiment is based on embodiment 1.

[0036] Specifically, the loading and unloading mechanism also includes a first conveyor belt 501 and a second conveyor belt 502. The second conveyor belt 502 is used to receive the object conveyed by the first conveyor belt 501. The second conveyor belt 502 and the first conveyor belt 501 are arranged parallel to each other or coplanarly. In this embodiment, the first conveyor belt 501 and the second conveyor belt 502 are arranged coplanarly.

[0037] The first conveyor belt 501 and the second conveyor belt 502 are not directly connected. There is a receiving space 503 between the first conveyor belt 501 and the second conveyor belt 502. The receiving space 503 is used to receive the suction cup 400. When the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 near the second conveyor belt 502, the suction cup 400 is stored in the receiving space 503, thereby preventing the object from being blocked by the suction cup 400 during the process of being transferred from the first conveyor belt 501 to the second conveyor belt 502.

[0038] Preferably, when the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 away from the second conveyor belt 502, that is, when the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 located at the right end of the limiting path 201, the suction cup 400 picks up the object, and then the suction cup 400 places the picked-up object on the first conveyor belt 501, and the first conveyor belt 501 then transfers the object to the second conveyor belt 502.

[0039] Preferably, the loading and unloading mechanism further includes a mounting plate 600, which is disposed on both sides of the first conveyor belt 501 and the second conveyor belt 502, and is used to connect the first conveyor belt 501 and the second conveyor belt 502. The mounting plate 600 is arranged parallel to the moving plate 300. The side of the mounting plate 600 is provided with a track groove 601, and the moving plate 300 is provided with a navigation component 301. In this embodiment, the navigation component 301 is a first roller, which is located in the track groove 601. When the moving plate 300 moves, the first roller rolls along the length direction of the track groove 601, which enhances the guidance and stability of the moving plate 300 when it moves, reduces the offset caused by mechanical vibration, and ensures the accuracy of the position adjustment of the suction cup 400.

[0040] Preferably, in this embodiment, the drive unit 101 is a servo motor, which is mounted at the bottom of the mounting plate 600. The drive shaft 102 is mounted on the mounting plate 600, and the output end of the servo motor drives the drive shaft 102 to rotate synchronously. The driven shaft 103 is mounted on the mounting plate 600, and is arranged parallel to the drive shaft 102. The driven shaft 103 and the drive shaft 102 are connected by a belt 104. The belt 104 drive between the drive shaft 102 and the driven shaft 103 can provide smooth power output, reduce the load on the drive unit 101, extend the service life of the equipment, and simplify the maintenance cost of the transmission system.

[0041] Preferably, the fixing block 701 is disposed on the moving plate 300, and the fixing block 701 passes through the track groove 601 on the side of the mounting plate 600; while the pressing block 702 is detachably mounted on the top of the fixing block 701 by bolts, and a pressing space is provided between the fixing block 701 and the pressing block 702 to accommodate the belt 104; when the drive shaft 102 rotates clockwise or counterclockwise, it drives the belt 104 to move back and forth along the length direction of the track groove 601. During this process, the belt 104, the fixing block 701, and the moving plate 300 move synchronously. The pressing space design of the fixing block 701 and the pressing block 702 ensures the synchronous movement of the belt 104 and the moving plate 300, avoids the belt 104 from slipping or disengaging, improves transmission reliability, and reduces downtime failures.

[0042] Furthermore, the side of the fixing block 701 facing the pressing block 702 or the side of the pressing block 702 facing the fixing block 701 is provided with a corrugated surface 703. By providing the corrugated surface 703, the resistance is increased when the fixing block 701 and the pressing block 702 press the belt 104, preventing the belt 104 from coming loose from the pressing space. The corrugated surface 703 increases the friction between the belt 104 and the pressing block 702, further preventing the belt 104 from coming loose and enhancing the stability of the transmission system, which is especially suitable for high-speed or heavy-load conditions.

[0043] Furthermore, a limiting member 302 is disposed on the moving plate 300, and the limiting member 302 is in contact with the limiting path 201. In this embodiment, the limiting member 302 is a second roller, which can roll along the path direction of the limiting path 201. When the moving plate 300 moves, it drives the second roller to roll along the path direction of the limiting path 201. The contact sliding or rolling of the limiting member 302 with the limiting path 201 provides double limiting protection, preventing the moving plate 300 from deviating from the predetermined path due to external force interference, and ensuring the accurate execution of the suction cup 400's movement.

[0044] When the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 located at the right end of the limiting path 201, the second roller is located in the limiting area 202 at the right end of the limiting path 201, and the suction cup 400 picks up the object; when the projection of the moving plate 300 on the limiting plate 200 coincides with the limiting area 202 located at the left end of the limiting path 201, the second roller is located in the limiting area 202 at the left end of the limiting path 201, and the suction cup 400 is stored in the receiving space 503, thereby preventing the object from being blocked by the suction cup 400 during the process of being transferred from the first conveyor belt 501 to the second conveyor belt 502.

[0045] Example 4

[0046] This embodiment is the fourth embodiment of the utility model, and this embodiment is based on embodiment 3.

[0047] This embodiment is basically the same as embodiment 3, except that the navigation component 301 in this embodiment is a first slider. The first slider is located in the track groove 601. When the moving plate 300 moves, the first slider slides along the length direction of the track groove 601.

[0048] Preferably, both the side of the fixing block 701 facing the pressing block 702 and the side of the pressing block 702 facing the fixing block 701 are provided with corrugated surfaces 703. The design of the double-sided corrugated surfaces 703 maximizes the contact area between the pressing block 702 and the fixing block 701, further improving the clamping force on the belt 104, adapting to more complex load changes, and improving the adaptability of the equipment.

[0049] Furthermore, the limiting member 302 is disposed on the moving plate 300, and the limiting member 302 is in contact with the limiting path 201. In this embodiment, the limiting member 302 is a second slider, which can slide along the path direction of the limiting path 201. When the moving plate 300 moves, it drives the second slider to slide along the path direction of the limiting path 201.

[0050] Example 5

[0051] This embodiment is based on the above embodiments and provides a loading and unloading vehicle with a loading and unloading mechanism. Integrating the loading and unloading mechanism into the vehicle achieves a modular design, facilitating installation and maintenance, while also expanding the vehicle's functionality and making it suitable for various logistics scenarios.

[0052] Based on the above, the beneficial effects of this utility model are as follows:

[0053] By driving the moving plate 300 to move, the limiting member 302 moves along the limiting path 201 on the limiting plate 200. When the limiting member 302 is located in the limiting area 202 at the right end of the limiting path 201, the suction cup 400 picks up the object. When the limiting member 302 is located in the limiting area 202 at the left end of the limiting path 201, the suction cup 400 is stored in the receiving space 503, thereby preventing the object from being blocked by the suction cup 400 during the process of being transported from the first conveyor belt 501 to the second conveyor belt 502. This allows for the adjustment of the position of the suction cup 400. By moving the moving plate 300 until its projection on the limiting plate 200 coincides with the corresponding limiting area, the suction or avoidance state of the suction cup can be switched.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
