DETAILED DESCRIPTION

[0041] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0042] This invention provides a device for loading and unloading materials along a circular track, such as... Figures 1-2 As shown, the system includes multiple guide rails 6 connected in sequence, a transport lifting and positioning mechanism 4, a carrier 5, a material picking mechanism 8, and a lifting mechanism 7. The carrier 5 is used to load material 10. The bottom of the carrier 5 is provided with a first positioning part 52 and a slider 51 adapted to the guide rails 6. The multiple guide rails 6 are provided with a loading position 1, a picking position 2, and a unloading position 3. Each section of the guide rail 6 is provided with a transport lifting and positioning mechanism 4. The transport lifting and positioning mechanism 4 includes a translation mechanism 41 and a lifting mechanism 44. The translation mechanism 41 is driven by a driving mechanism to reciprocate between each section of the guide rail 6. The lifting mechanism 44 is located on the translation mechanism 41. The lifting mechanism 44 is provided with multiple second positioning parts 42 adapted to the first positioning part 52. The material picking mechanism 8 is located on one side of the picking position 2, between the picking position 2 and the transport belt 9. The lifting mechanism 7 is located next to the material picking position 2. The lifting mechanism 7 includes a lifting and translation mechanism 71, and the lifting and translation mechanism 71 is provided with a third positioning part 72 that is adapted to the first positioning part 52.

[0043] Vehicle 5 Figures 3-4 As shown, the bottom of the carrier 5 is provided with a first positioning part 52 and a slider 51. The slider 51 is adapted to the guide rail 6 so as to slide on the guide rail 6. The first positioning part 52 is adapted to the second positioning part 42 or the third positioning part 72 so as to position the carrier 5. The carrier 5 is provided with multiple material positions, with a large loading capacity, which can realize the loading of batch materials 10. The materials 10 in each material position are loaded layer by layer. Different carriers 5 can be used to load different types of materials 10, so as to realize the loading and unloading of different types of paper, alcohol swabs and other accessories that require manual feeding, making the device more applicable. A guide shaft 53 is provided to put in the materials 10, and an inverted anti-return mechanism 54 is provided to fix the materials 10 and prevent the materials 10 from shifting during the sliding process.

[0044] In this embodiment, the carrier 5 is a magazine-type carrier, the first positioning part 52 is a pin hole, and the second positioning part 42 and the third positioning part 72 are pins. The carrier 5 is positioned on the transport lifting and positioning mechanism 4 by the adaptation of the first positioning part 52 and the second positioning part 42, and moves from the loading position 1 along... Figure 1 The carrier 5 is driven to slide sequentially on the multi-segment guide rail 6 in a clockwise direction; the carrier 5 is positioned on the lifting mechanism 7 by the first positioning part 52 and the third positioning part 72, and is driven to rise at the material picking position 2 to pick up the material. The material picking mechanism 8 is a material picking robot.

[0045] Handling, lifting, and positioning mechanism 4 Figure 5As shown, the system includes a translation mechanism 41, a lifting mechanism 44, a translation motor 43, a linear bearing 47, a base plate 45, and a flat plate 46. The translation motor 43 is connected to the translation mechanism 41. The base plate 45 is mounted on the translation mechanism 41. The base plate 45 is connected to the flat plate 46 via the linear bearing 47 and the lifting mechanism 44. A second positioning part 42, adapted to the first positioning part 52, is mounted on the flat plate 46. The lifting mechanism 44 is used to raise the flat plate 46, and the linear bearing 47 is used for guidance, ensuring that the flat plate 46 is vertically upward along the axis of the linear bearing 47, so that the second positioning part 42 can be accurately inserted into the first positioning part 52. The translation mechanism 41 uses a servo motor for power and a lead screw and slider for traction, driving the carrier 5 to slide on the guide rail 6.

[0046] The number of second positioning parts 42 on a conveying, lifting, and positioning mechanism 4 can be multiple times the number of first positioning parts 52 on a carrier 5, allowing the translation mechanism 41 of a section of guide rail 6 to simultaneously drive multiple carriers 5 to slide, further increasing the load capacity of the material 10 and improving the feeding efficiency. In this embodiment, the lifting mechanism 44 is a lifting cylinder, adapted to heavy loads, to lift multiple carriers 5 loaded with multiple layers of material 10; the translation mechanism 41 is a linear module that realizes linear translation of the load, and the translation speed is adjusted by the translation motor 43.

[0047] Lifting mechanism 7 Figure 6 As shown, it includes a lifting and translating mechanism 71, a lifting motor 73, and a support plate 74. The lifting motor 73 is connected to the lifting and translating mechanism 71. The support plate 74 is provided with a third positioning part 72, which is adapted to the first positioning part 52. The support plate 74 is installed on the lifting and translating mechanism 71 and rises with the lifting and translating mechanism 71.

[0048] In this embodiment, the lifting and translating mechanism 71 is a linear module that realizes the linear upward translation of the load, and the lifting speed is adjusted by the lifting motor 73.

[0049] The multi-segment guide rail 6 includes a first segment 6, a second segment 6, ..., an i-th segment 6, ..., and an n-th segment 6 connected sequentially, where n ≥ 2. The initial end of the first segment 6 is the loading position 1, the n-th segment 6 has a material picking position 2, and the end of the n-th segment 6 has a material unloading position 3. The material picking position 2 is used to unload the material 10 from the full container 5, and the material unloading position 3 is used to unload the empty container 5. The intersection of the various segments 6 is the transfer position. The container 5 slides sequentially from the first segment 6 to the n-th segment 6 under the drive of the translation mechanism 41, and the translation mechanism 41 is changed at the transfer position. The sequentially connected multi-segment guide rail 6 makes the arrangement of the guide rail 6 more diversified and also accelerates the material 10 transmission speed.

[0050] Therefore, the operating method of the device for loading and unloading on a circulating track includes:

[0051] S1, put the full load carrier 5 into the loading position 1; let i = 1;

[0052] S2, the translation mechanism 41 of the i-th section of guide rail 6 returns to the initial position, the jacking mechanism 44 jacks up, so that the second positioning part 42 rises and inserts into the first positioning part 52, the translation mechanism 41 drives the carrier 5 to slide, after sliding to the position where the two sections of guide rail 6 intersect, the jacking mechanism 44 lowers, so that the second positioning part 42 lowers and disengages from the first positioning part 52, the carrier 5 disengages from the carrying and jacking positioning mechanism 4 of the i-th section of guide rail 6; then, the translation mechanism 41 of the i-th section of guide rail 6 retreats to the initial position, waiting for the next full load carrier 5 to be put in;

[0053] S3, let i = i + 1, judge whether i is equal to n, if not, return to step S2, if yes, enter step S4;

[0054] S4, the translation mechanism 41 of the n-th section of guide rail 6 returns to the initial position, the jacking mechanism 44 jacks up, so that the second positioning part 42 rises and inserts into the first positioning part 52, the translation mechanism 41 drives the carrier 5 to slide, after sliding to the loading position 2, the unloading mechanism 8 unloads all the materials 10 on the full load carrier 5 to the carrying belt 9, the translation mechanism 41 continues to drive the empty carrier 5 to slide, after sliding to the unloading position 3, the jacking mechanism 44 lowers, so that the second positioning part 42 lowers and disengages from the first positioning part 52, the carrier 5 disengages from the carrying and jacking positioning mechanism 4 of the n-th section of guide rail 6; then, the translation mechanism 41 of the n-th section of guide rail 6 retreats to the initial position, waiting for the next full load carrier 5 to be put in;

[0055] Since the unloading mechanism 8 can generally only unload at a fixed height, which may not be consistent with the height of the loaded materials 10 in the carrier 5, the jacking mechanism 7 needs to adjust the height of the carrier 5, and the carrier 5 loads multiple layers of materials 10, therefore, the method for the unloading mechanism 8 to unload all the materials 10 on the full load carrier 5 includes:

[0056] A1, after the full load carrier 5 slides to the unloading position 3, the jacking mechanism 44 lowers, so that the second positioning part 42 lowers and disengages from the first positioning part 52, the carrier 5 disengages from the carrying and jacking positioning mechanism 4 of the n-th section of guide rail 6;

[0057] A2, the jacking and translation mechanism 71 rises, the third positioning part 72 inserts into the first positioning part 52, the jacking and translation mechanism 71 drives the carrier 5 to rise to the operable height of the unloading mechanism 8;

[0058] A3, the unloading mechanism 8 unloads a layer of materials 10 on the full load carrier 5 to the carrying belt 9, the jacking and translation mechanism 71 drives the carrier 5 to rise by the thickness of the materials 10, unloads a layer of materials 10 to the carrying belt 9, until all the materials 10 are unloaded;

[0059] A4. The lifting and translation mechanism 71 descends to its original height, the third positioning part 72 disengages from the first positioning part 52, the empty carrier 5 disengages from the lifting mechanism 7, the empty carrier 5 falls back onto the guide rail 6, and the second positioning part 42 is inserted back into the first positioning part 52.

[0060] S5. While the material handling mechanism 8 is handling the material, the empty carrier 5 at the unloading position 3 is filled with material 10, and then the process returns to step S1.

[0061] In this step, while the material handling mechanism 8 is handling the material, the empty carrier 5 at the unloading position 3 can be removed, filled with material 10, and then returned to arrangement S1. The carrier 5 filled with material 10 is then placed into the loading position 1 to begin the next cycle. The removal, filling, and placement can be done manually or mechanically. This also applies if there is a connection between the unloading position and the loading position 1, and the empty carrier 5 does not need to be removed.

[0062] This embodiment uses four guide rails 6 with n=4 as an example. In the above operation method, while the translation mechanism 41 of each guide rail 6 drives the carrier 5 to slide on the guide rail 6, the translation mechanism 41 of the previous guide rail 6 returns to the initial position, waiting for the next carrier 5 filled with material to be placed in. The translation mechanism 41 of each guide rail 6 continues to cycle back and forth without stopping, which helps to improve the transport speed of the material 10. The material 10 on multiple carriers 5 is picked up from the picking position 2 and transferred to the conveyor belt 9 in sequence. The material 10 buffer is sufficient, and the conveyor belt 9 can achieve automatic feeding without stopping.

[0063] In summary, the above-described device and its operating method for loading and unloading materials on a circulating track have the following advantages:

[0064] (1) The reciprocating motion of the multi-section guide rail translation mechanism of the present invention is achieved by the positioning part on the carrier and the positioning part on the translation mechanism to position the carrier. The guide rail slider splicing design allows the translation mechanism to pull the carrier to slide on the guide rail. The carrier is pulled to the material picking position and picked up the material onto the conveyor belt in sequence without stopping. After the empty carrier is loaded, it is placed back to the loading position to enter the cycle. This allows the conveyor belt to automatically add material without stopping, reducing the time wasted on material feeding and stopping the machine. The material buffer is sufficient. Moreover, the translation mechanism of the multi-section guide rail pulls the carrier at the same time, which improves the material transmission speed, further increases the material buffer, and improves the work efficiency.

[0065] (2) The carrier of the present invention can carry a large amount of materials, the lifting cylinder can withstand a large load, improve the material transmission volume, and can carry different types of materials, reduce the material changeover time, thereby improving the material transmission efficiency and increasing the material buffer capacity; and a translation mechanism can simultaneously pull multiple carriers through the positioning part, further improving the material transmission volume and work efficiency.

[0066] (3) The carrier of the present application realizes positioning or disengagement through the jacking mechanism, realizes switching of the guide rails without turning, is beneficial to improving the transmission efficiency, and is beneficial to reducing shaking without turning, reducing damage and waste of the materials, and diversifying the arrangement of the guide rails;

[0067] (4) The present application realizes adjustment of the height of the carrier when taking materials through the jacking mechanism, realizes automatic layering and taking of materials in cooperation with the taking mechanism, is convenient and safe for taking and placing, and avoids damage and waste of the materials;

[0068] (5) The translation mechanism and the jacking translation mechanism of the present application are both driven by servo, are stable in operation, are noiseless, are high in precision level, and are easy to adjust the material transmission speed according to the actual demand;

[0069] (6) The parts of the present application are spliced in a modular manner, are fast in production, and are convenient to replace.

[0070] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the embodiments of the present application are described in combination with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the appended claims.
