DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a horizontal conveying component 100 and a buffer component 200 of a logistics loading and unloading conveyor. In the logistics system, the upstream conveying rate and the downstream conveying rate are often not completely consistent. This embodiment implements the buffering effect in the logistics loading and unloading process, helps balance the two rates, and ensures that the transportation will not stagnate or exceed due to short-term fluctuations at the export end.

[0031] Specifically, the horizontal conveying assembly 100 includes a frame 110 and a belt conveyor 120 . The belt conveyor 120 is installed on the frame 110 and is used to convey goods.

[0032] Reference Figure 1 and Figure 2The belt conveyor 120 is a main component for conveying goods, preferably, including rollers 121, belts 122 and first motors 123. The rollers 121 are one of the key components of the belt conveyor 120, which are rotatably mounted at both ends of the frame 110 and fixed to the frame 110 through bearings or sleeves. The first motor 123 is the power source for driving the belt conveyor 120, which is mounted on the frame 110 and connected to the rollers 121 through a coupling, converting the rotation of the first motor 123 into the rotation of the rollers 121. The belt 122 is the part that directly contacts and carries the goods, and is tensioned on the rollers 121 at both ends to form a closed loop. The selection of the belt 122 needs to consider factors such as the weight of the goods and the friction coefficient.

[0033] When the first motor 123 is started, it drives the active roller 121 to rotate through the coupling. The rotation of the active roller 121 is transmitted to the driven roller 121 at the other end through the belt 122, so that the belt 122 moves along a closed loop. After the goods are placed on the belt 122, as the belt 122 moves, the goods are also transported to the predetermined position.

[0034] Specifically, the cache assembly 200 is installed on the rack 110 , and includes a cover shell 210 , a storage rack 220 , and a driving unit 230 . The storage rack 220 is lifted and lowered along the Y direction in the cover shell 210 by the driving unit 230 .

[0035] Among them, Figure 1 As shown, the Y direction is perpendicular to the belt 122 .

[0036] Reference Figure 2 and Figure 3 Preferably, the storage rack 220 includes a door-shaped plate 221 and a support plate 222. The door-shaped plate 221 serves as the main frame of the storage rack 220 and provides structural support. A plurality of support plates 222 are provided and are equidistantly installed in the door-shaped plate 221 along the X direction to form a multi-layer storage space. The number of storage layers can be flexibly adjusted according to actual needs to meet the storage needs of different types of goods. There is a storage space for storing goods between the upper and lower adjacent support plates 222. The storage space has an output or input entrance and exit along the X direction to facilitate the entry and exit of goods.

[0037] Among them, Figure 2 As shown, the X direction and the Y direction are perpendicular to each other and parallel to the moving direction of the belt 122 .

[0038] Preferably, the driving unit 230 includes a screw rod 231, a second motor 232, a bevel gear set 233 and a slide rail slider mechanism 234, the screw rod 231 and the slide rail slider mechanism 234 are respectively installed on both sides of the door plate 221, the slide rail slider mechanism 234 constrains the rotation degree of the door plate 221, so that the door plate 221 can be lifted and lowered by the drive of the second motor 232, the second motor 232 is fixedly mounted on the cover 210, and the second motor 232 is connected to the screw rod 231 through the bevel gear set 233, wherein the bevel gear set 233 serves as a deceleration and transmission device to convert the rotational motion of the second motor 232 into a low-speed and high-torque motion suitable for the operation of the screw rod 231.

[0039] Furthermore, the width of the belt 122 in the Z direction is L1, the width of the goods in the Z direction is L2, and the width of the support plates 222 on both sides in the Z direction is L3; wherein L1<L2<L3. Such a design can ensure that the goods will not slip off the edge of the belt 122 during transportation, and there is enough space to accommodate the goods when they are stored in the storage rack 220.

[0040] Among them, the Z direction and the Y direction belong to two spaces perpendicular to each other, and the Z direction and the X direction are in the same space, and the Z direction and the X direction extend perpendicularly to each other in the same space, such as Figure 2 As shown, the Z direction is perpendicular to the movement direction of the belt 122 .

[0041] When the goods are transported to the cache component 200 through the belt conveyor part 120 of the horizontal conveying component 100, the goods enter the accommodating space through the entrance and exit of the storage rack 220, and the second motor 232 is started, driving the screw 231 to rotate through the bevel gear set 233, thereby causing the storage rack 220 to rise and fall in the horizontal direction along the slide rail slider mechanism 234 until the goods find a suitable storage position. When the goods need to be taken out, the storage rack 220 is again moved horizontally to a suitable height under the control of the drive unit 230, and the goods are removed through the entrance and exit. By continuously transferring the goods from the input end to the output end, in conjunction with the automatically lifting cache component 200, the rapid transportation of goods is realized, the efficiency of the overall logistics system is improved, and the cache component 200 can serve as a bridge between different processes or equipment to promote the integration and coordination of the entire system.

[0042] Embodiment 2:

[0043] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: this embodiment provides a sliding portion 240 of a logistics loading and unloading conveyor, through which higher efficiency and flexibility are achieved in the logistics system.

[0044] Specifically, a slide groove 201 is provided on one side of the support plate 222 close to the belt 122 and is matched with a sliding portion 240. The slide groove 201 may be a U-shaped or T-shaped groove to ensure that the sliding portion 240 can slide smoothly therein and can be firmly fixed at a desired position. The sliding portion 240 can be matched and fixed with the belt 122. The sliding portion 240 can slide in the slide groove 201 and can be matched and fixed with the belt 122 to ensure that the goods can be smoothly moved from the belt 122 to the support plate 222 during the storage and retrieval process. or moves from the support plate 222 to the belt 122; wherein, a sensing system 130 is fixedly mounted on the frame 110 for detecting the position of the sliding portion 240, and then controlling the movement or stop of the sliding portion 240 on the frame 110. Commonly used sensors include photoelectric sensors, proximity sensors, magnetic induction sensors, etc., which can accurately detect the position of the sliding portion 240. The sensing system 130 is usually connected to the control system, and controls the action of the sliding portion 240 through signal transmission to ensure that it runs according to a predetermined program.

[0045] In one application scenario of the sliding portion 240:

[0046] Goods storage process:

[0047] 1. When the goods reach the end of the belt 122, the sliding part 240 is first fixed with the belt 122.

[0048] 2. The sliding part 240 slides toward the support plate 222 through the slide groove 201 to smoothly transfer the goods from the belt 122 to the support plate 222 .

[0049] 3. The sensing system 130 detects the position of the sliding part 240 and controls it to stop, ensuring that the goods are completely separated from the belt 122 and safely placed on the support plate 222.

[0050] Cargo removal process:

[0051] 1. When the goods need to be taken out, the sensor system 130 detects the position of the sliding part 240 and controls it to start moving.

[0052] 2. The sliding part 240 slides from the support plate 222 toward the belt 122 to smoothly transfer the goods from the support plate 222 to the belt 122 .

[0053] 3. After the sensing system 130 detects that the sliding part 240 has reached the designated position, it controls it to stop and fix it to the belt 122 to ensure that the goods are completely separated from the support plate 222 and safely placed on the belt 122.

[0054] Reference Figure 3 and Figure 4 and Figure 5The sliding part 240 is designed to be able to slide freely in the slide groove 201, and usually includes components such as pulleys or sliders to reduce friction. The sliding part 240 also includes a fixing device, such as a locking pin or an electromagnetic lock, which can fix the sliding part 240 at a specified position to ensure that the goods do not slide during movement. Preferably, the sliding part 240 includes a plurality of flat plates 241 that are rotatably connected end to end. The design of the flat plates 241 enables the sliding part 240 to adapt to different curvature radii to ensure that it can stably contact the belt 122 at different positions. The flat plate 241 has a slot 202, and an electromagnet 242 is fixedly installed on the inner wall of the slot 202 at the head end. A magnetic attraction part that matches the electromagnet 242 is provided on the belt 122, wherein the magnetic attraction part includes a protrusion 101 fixedly installed on the surface of the belt 122, the protrusion 101 is adapted to the slot 202, and a magnetic sheet 140 that is attracted by the electromagnet 242 is fixedly installed on the surface of the protrusion 101 ， The electromagnet 242 generates a magnetic field when powered on, and can attract the magnetic sheet 140 on the surface of the belt 122 , thereby fixing the positional relationship between the sliding portion 240 and the belt 122 .

[0055] Furthermore, the flat plate 241 has a first mounting groove 203 and a second mounting groove 204 inside, and the second mounting groove 204 is symmetrically arranged with the first mounting groove 203 as the axis, and the first mounting groove 203 and the second mounting groove 204 are perpendicular to each other; wherein, a moving block 243 is installed in the first mounting groove 203 through an elastic member, and the elastic member is preferably a spring 245, and a sliding pin 244 is slidably installed in the second mounting groove 204, and the sliding pin 244 abuts against the inclined surface of the moving block 243, thereby controlling the extension or retraction of the sliding pin 244, and the sliding groove 201 and the frame 110 are both provided with a pin hole 205 adapted to the sliding pin 244, and when the moving block 243 moves, the sliding pin 244 is pushed to extend outward or retract inward through the inclined surface, and the sliding pin 244 can cooperate with the pin hole 205 on the sliding groove 201 and the frame 110 to achieve the fixing or unlocking of the sliding part 240.

[0056] During the process of storing goods, the electromagnet 242 of the sliding part 240 is not energized, and the sliding part 240 is in a free state. When the goods reach the end of the belt 122, the electromagnet 242 of the sliding part 240 is energized to generate a magnetic field and adsorb to each other with the magnetic sheet 140 on the surface of the belt 122. The sliding part 240 is combined with the protrusion 101 on the surface of the belt 122 through the card slot 202, and is fixed together by the adsorption effect of the electromagnet 242 and the magnetic sheet 140. The sliding part 240 slides onto the support plate 222 together with the goods. When the sliding part 240 reaches the specified position, the electromagnet 242 is powered off, the sliding part 240 is separated from the belt 122, and the goods remain on the support plate 222. The sensor system 130 detects the position of the sliding part 240 and controls it to stop, ensuring that the goods are completely separated from the belt 122 and safely placed on the support plate 222.

[0057] During the process of taking out the goods, the electromagnet 242 of the sliding part 240 is not energized, and the sliding part 240 is in a free state. When the goods need to be taken out, the sliding part 240 moves to the bottom of the goods on the support plate 222, and the electromagnet 242 of the sliding part 240 is energized to generate a magnetic field and adsorb to the magnetic sheet 140 on the surface of the belt 122. The sliding part 240 slides onto the belt 122 together with the goods. When the sliding part 240 reaches the specified position, the electromagnet 242 is powered off, the sliding part 240 is separated from the belt 122, and the goods remain on the belt 122. After the sensor system 130 detects that the sliding part 240 has reached the specified position, it controls it to stop and fixes it to the belt 122 to ensure that the goods are completely detached from the support plate 222. The support plate 222 is safely placed on the belt 122. The sensing system 130 can use photoelectric sensors, proximity sensors, magnetic induction sensors, etc. to detect the position of the sliding part 240. After the sensor detects the position of the sliding part 240, it transmits the signal to the control system. The control system determines whether the sliding part 240 has reached the predetermined position based on the signal sent by the sensor. When the sliding part 240 reaches the predetermined position, the control system sends an instruction to control the sliding part 240 to stop, and fixes it through the electromagnet 242 or the sliding pin 244. Through the cooperation of the sliding pin 244 and the pin hole 205, the sliding part 240 can be fixed at any preset position to ensure the stability of the goods during the storage and retrieval process.

[0058] It should be noted that when there is material in the storage rack 220 , the driving unit 230 drives the storage rack 220 to descend, so that the end surface of the support plate 222 with material at the lower end is slightly lower than the belt 122 .

[0059] By precisely controlling the descending position of the storage rack 220, ensuring that the end surface of the support plate 222 is slightly lower than the belt 122, the instability factors of the goods during the transfer process are reduced. By precisely controlling the descending position of the storage rack 220, ensuring that the end surface of the support plate 222 is slightly lower than the belt 122, the instability factors of the goods during the transfer process are reduced, and the goods are smoothly transferred from the support plate 222 to the belt 122, reducing the risk of sliding or falling due to height difference.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
