Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sorting conveying, in particular to a GTP goods-to-person system. BACKGROUND

[0002] The GTP (Goods to Person) intelligent logistics management mode is a mode for realizing intelligent management of warehousing and logistics by using technologies such as the Internet of Things, big data and artificial intelligence. The core is to improve efficiency and optimize resource allocation through automatic equipment, which is suitable for order picking in e-commerce or book industry.

[0003] The traditional GTP system, such as the utility model patent named "Double-layer express sorting device" disclosed in Chinese patent publication No. CN217971428U, includes at least one conveying device, a controller, at least one identification device, at least one sorting conveying member and at least one set of position sensors. The conveying device is used to convey the express package from a starting end to an ending end. The identification device includes an identification member that can read an information identifier of the express package conveyed by the conveying device and is in communication connection with the controller. The position sensor is in communication connection with the controller. The sorting conveying member includes at least one sorting conveying assembly. Each position sensor can sense the express package on the corresponding sorting conveying assembly. When the express package moves to the corresponding sorting conveying assembly, the controller controls the corresponding sorting conveying assembly to work, so that the corresponding sorting conveying assembly moves the express package that meets the conditions from a sorting area.

[0004] When the picker uses the above device, the picker needs to take out the goods from the warehouse according to the task assigned by the order system, and then sends the material storage box to the picker through the conveying system. The picker picks the order materials into the corresponding order box through the special GTP turnover picking equipment until the order picking is completed. At this time, the GTP system confirms the completion of the order, and the order box is conveyed to the warehouse, and the storage box is conveyed back to the warehouse.

[0005] The above-mentioned GTP goods-to-person system adopts a double-layer structure with upper-layer conveying materials and lower-layer material sorting. The picker needs to frequently operate between the upper and lower layers, and the labor intensity of the picker is large and needs to bend frequently. Moreover, the efficiency of the material transmission between the double-layer conveying structure is relatively low.

[0006] Therefore, the present application provides a GTP goods-to-person system to solve the problem of low efficiency of the double-layer conveying line sorting mentioned in the background. SUMMARY

[0007] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a GTP goods-to-person system to solve the problem of low sorting efficiency of double-layer conveyor lines mentioned in the prior art.

[0008] To achieve the above and other related objectives, the present invention provides a GTP goods-to-person system, including a horizontal conveying mechanism and a tumbler conveying mechanism. The tumbler conveying mechanism is arranged in several groups, and all the tumbler conveying mechanisms are combined to form a sorting mechanism. The several tumbler conveying mechanisms are arranged in parallel, and two adjacent tumbler conveying mechanisms are attached together. The horizontal conveying mechanism is arranged at both ends of the sorting mechanism, and each tumbler conveying mechanism can be tumbled independently.

[0009] The reversible conveying mechanism includes a support frame and side baffles. A horizontal support frame is provided in the middle between the two inner walls of the support frame. A reversible motor is provided on the horizontal support frame. The output shaft of the reversible motor is provided with a drive rod.

[0010] The top edge of the support frame is symmetrically provided with a conveyor connection seat;

[0011] There are two side baffles, and a traction connecting rod is provided between the two side baffles. The traction connecting rod passes through the two conveying part connecting seats respectively, so that the side baffles can rotate around the traction connecting rod as the pivot. The inner wall of one of the side baffles is rotatably connected to the drive rod.

[0012] The two side baffles are connected to the same end of a first conveyor roller connecting frame, and the other end of the two side baffles is provided with a second conveyor roller connecting frame. A number of material conveying rollers are provided between the first conveyor roller connecting frame and the second conveyor roller connecting frame. All the material conveying rollers are interconnected and driven to rotate by a motor.

[0013] Preferably, the end of the drive rod away from the output shaft of the flipping motor is provided with a rotatable traction roller shaft;

[0014] The inner wall of the side baffle connected to the drive rod is provided with a drive sleeve, and the outer surface of the traction roller shaft is fitted with the inner wall of the drive sleeve with a small clearance.

[0015] Preferably, a flip-stop frame is provided on one side of the support frame, and the flip-stop frame is provided with an arc-shaped guide groove;

[0016] One of the side baffles has a limiting guide rod on its inner wall. The limiting guide rod extends into the interior of the guide groove and can slide along the trajectory of the guide groove.

[0017] Preferably, the second conveyor roller connecting frame is located on the lower side of the side baffle after it is flipped over, and the top of the second conveyor roller connecting frame is higher than the top of the side baffle.

[0018] Preferably, the first conveyor roller connecting frame has a cavity inside, and one end of all the material conveying rollers extends into the cavity inside the first conveyor roller connecting frame and is connected to each other through transmission.

[0019] Preferably, the second conveyor roller connecting frame has a plurality of equally spaced anti-wear rollers at one end facing the material conveyor roller, and each of the anti-wear rollers can rotate.

[0020] Preferably, the top of the material conveying roller is flush with the top of the horizontal conveying mechanism.

[0021] Preferably, the sides of the horizontal conveying mechanism and the tumbler conveying mechanism are provided with limiting mechanisms for supporting and limiting the material box during inclined conveying. The limiting mechanism includes a protective frame, the inner side of which is connected to the outer surface of all horizontal conveying mechanisms and all tumbler conveying mechanisms respectively. The top of the protective frame is provided with a diagonal support plate, which is inclined outward.

[0022] Preferably, the side of the inclined support plate facing the flip-up conveyor mechanism is at a 45-degree angle to the vertical line.

[0023] Preferably, a damping device is provided in the gap between the second conveyor roller connecting frame and the anti-wear roller. The damping device includes an elastic damping plate, an electromagnet is provided on the side of the damping plate facing the second conveyor roller connecting frame, and a permanent magnet is provided on the other side of the damping plate.

[0024] When the electromagnet is energized, it can attract or repel the permanent magnet.

[0025] As described above, the GTP goods-to-person system of the present invention has the following beneficial effects:

[0026] 1. During the normal conveying of the material box, the material conveying roller is horizontal with the horizontal conveying mechanism. When sorting is required, the GTP system controls the corresponding position of the flipping motor to drive the drive rod to flip, so that the opening of the material box faces the sorting personnel, so that the sorting personnel can easily pick up and place the goods. After the goods are sorted, the side baffle returns to the horizontal state and continues to convey. The single-layer conveying flipping mode realizes efficient conveying and sorting, and allows sorting personnel to operate without bending over, reducing labor consumption.

[0027] 2. This invention designs the top of the second conveyor roller connecting frame to be higher than the top of the side baffle, so that after the side baffle is flipped, the material box can be supported by the second conveyor roller connecting frame to prevent the material box from sliding. At the same time, an anti-wear roller is set on the side of the second conveyor roller connecting frame facing the material conveyor roller. The anti-wear roller can effectively reduce the friction between the material box and the second conveyor roller connecting frame, so that the material box can continue to be conveyed after it is flipped, further improving the sorting efficiency.

[0028] 3. This invention provides a flip-limiting frame on the side of the support frame, and the guide groove on the flip-limiting frame cooperates with the limiting guide rod on the inner wall of the side baffle to limit the maximum flip angle of the side baffle, which can effectively prevent the material in the material box from falling out of the material box. At the same time, protective frames are provided on the sides of the horizontal conveying mechanism and the flip-able conveying mechanism, and a diagonal support plate is provided on the top of the protective frame. After the side baffle flips, the diagonal support plate can further limit the flip angle of the side baffle, and can further support the material box through the diagonal support plate, thereby achieving the effect of further improving the conveying stability.

[0029] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0042] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0043] Please see Figures 1 to 8 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0044] like Figures 1-5As shown, this invention provides a GTP (Goods-to-Person) system, including a horizontal conveyor mechanism 1 and a reversible conveyor mechanism 2. The horizontal conveyor mechanism 1 is a conventional roller conveyor line. Several sets of reversible conveyor mechanisms 2 are arranged, and all reversible conveyor mechanisms 2 are combined to form a sorting mechanism. Several reversible conveyor mechanisms 2 are arranged in parallel, and adjacent reversible conveyor mechanisms 2 are attached together. The horizontal conveyor mechanism 1 is located at both ends of the sorting mechanism, and each reversible conveyor mechanism 2 can be independently flipped. In use, the material box containing the material is conveyed to the conveying range of the reversible conveyor mechanism 2 through the horizontal conveyor mechanism 1. The reversible conveyor mechanism 2 identifies the order and goods according to the GTP system. When the target material arrives at the target area, the reversible conveyor mechanism 2 flips, so that the material box is tilted towards the sorting personnel. The sorting personnel can sort the material in the material box while standing or sitting. The sorted material box continues to be conveyed through the subsequent horizontal conveyor mechanism 1. The above structure achieves the effect of single-layer conveying and flipping. The material does not need to be transferred between the upper and lower conveying devices, which improves the conveying efficiency and sorting efficiency, and reduces the consumption of human resources.

[0045] Specifically, the flip-up conveyor mechanism 2 includes a support frame 21 and a side baffle 29. A horizontal support frame 22 is provided in the middle between the two inner walls of the support frame 21. A flip motor 23 is provided on the horizontal support frame 22. The flip motor 23 is a drive device with an adjustable flip angle, such as a servo motor or a stepper motor. The flip motor 23 is connected to the GTP system via a data cable and controlled by the control device in the GTP system. The starting, stopping, speed and other operating parameters of the flip motor 23 are controlled according to the data of the GTP system. The output shaft of the flip motor 23 is provided with a drive rod 24. The top edge of the support frame 21 is symmetrically provided with a conveyor connection seat 26.

[0046] There are two side baffles 29. A traction connecting rod 291 is provided between the two side baffles 29 to connect them together. The traction connecting rod 291 passes through the two conveying section connecting seats 26 respectively, so that the side baffles 29 can rotate about the traction connecting rod 291 as the axis of rotation. The inner wall of one of the side baffles 29 is rotatably connected to the drive rod 24. When the drive rod 24 is driven by the flipping motor 23 to rotate, the drive rod 24 will push the side baffle 29 to rotate about the traction connecting rod 291 as the axis, so as to realize the flipping operation of the side baffle 29.

[0047] The same end of the two side baffles 29 is connected to the first conveyor roller connecting frame 210, and the other end of the two side baffles 29 is provided with the second conveyor roller connecting frame 211. A number of material conveying rollers 212 are provided between the first conveyor roller connecting frame 210 and the second conveyor roller connecting frame 211. All material conveying rollers 212 are connected to each other through chains, belts, gears and other structures, and one of the material conveying rollers 212 is driven by a motor to rotate, so as to realize the synchronous rotation of all material conveying rollers 212 to convey the material box.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the end of the drive rod 24 away from the output shaft of the flipping motor 23 is provided with a rotatable traction roller shaft 25, which is a bearing structure; the inner wall of the side baffle 29 connected to the drive rod 24 is provided with a drive sleeve 293, and the outer surface of the traction roller shaft 25 is fitted with the inner wall of the drive sleeve 293 with a small clearance. Thus, when the drive rod 24 drives the side baffle 29 to flip, the friction can be reduced by the cooperation of the traction roller shaft 25 and the drive sleeve 293, thereby improving the service life of the equipment, especially when the material weight is large.

[0049] like Figure 5 and Figure 6 As shown in some embodiments, a flipping limiting frame 27 is provided on one side of the support frame 21 of the present invention, and an arc-shaped guide groove 28 is provided on the flipping limiting frame 27; a limiting guide rod 292 is provided on the inner wall of one of the side baffles 29, the limiting guide rod 292 extends into the interior of the guide groove 28, and can slide along the trajectory of the guide groove 28; when the side baffle 29 is driven to flip, the limiting guide rod 292 slides along the trajectory inside the guide groove 28, and when the limiting guide rod 292 abuts against the end of the guide groove 28, the maximum flipping angle of the side baffle 29 is limited, so as to prevent the side baffle 29 from flipping excessively and causing the material in the material box to fall out of the material box, and to make the flipping angle of the material box suitable for sorting personnel to sort materials.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the second conveying roller connecting frame 211 of the present invention is located on the lower side of the side baffle 29 after it is flipped, and the top of the second conveying roller connecting frame 211 is higher than the top of the side baffle 29. When the side baffle 29 is flipped, the material box on the surface of the material conveying roller 212 will slide to one side under the action of gravity along with the side baffle 29. At this time, the second conveying roller connecting frame 211 plays the role of supporting and limiting the material box, preventing the material box from sliding off the surface of the material conveying roller 212.

[0051] It should be noted that in some embodiments, the first conveying roller connecting frame 210 of the present invention has a cavity inside, and one end of all material conveying rollers 212 extends into the cavity inside the first conveying roller connecting frame 210 and is connected to each other through transmission structures such as belts, chains, and gears. Thus, the first conveying roller connecting frame 210 protects the connection of the material conveying rollers 212, and improves safety while realizing mutual transmission between the material conveying rollers 212.

[0052] like Figure 1 and Figure 7 As shown, in some embodiments, the second conveying roller connecting frame 211 of the present invention has a plurality of equally spaced anti-wear rollers 2111 on the side facing the material conveying roller 212. Each anti-wear roller 2111 can rotate. When the material box slides toward the second conveying roller connecting frame 211 due to the flipping of the side baffle 29, the outer surface of the material box will abut against the outer surface of the anti-wear roller 2111. At this time, the material conveying roller 212 can continue to convey the material box. During the movement of the material box, the anti-wear roller 2111 will be driven to rotate, thereby converting hard friction into rolling friction to reduce friction and improve the stability of the material box conveying.

[0053] like Figure 1 As shown, in some embodiments, the top of the material conveying roller 212 of the present invention is flush with the top of the horizontal conveying mechanism 1. When the material is conveyed from the horizontal conveying mechanism 1 to the surface of the material conveying roller 212 or through the material conveying roller 212 to the surface of the horizontal conveying mechanism 1, the material box can be smoothly transferred, avoiding the material box from vibrating or being blocked due to the drop, thereby improving the stability of the material box conveying.

[0054] like Figure 1 As shown, in some embodiments, the horizontal conveying mechanism 1 and the flip-over conveying mechanism 2 of the present invention are provided with a limiting mechanism 3 on their sides for supporting and limiting the material box during inclined conveying. The limiting mechanism 3 improves the stability of the material box conveying by increasing the supporting area and prevents the material in the material box from tipping over due to inclination.

[0055] like Figure 1 As shown, in some embodiments, the limiting mechanism 3 of the present invention includes a protective frame 31. The inner side of the protective frame 31 is connected to the outer surfaces of all horizontal conveying mechanisms 1 and all rotatable conveying mechanisms 2, respectively, to make the entire conveying line a whole. The top of the protective frame 31 is provided with a diagonal support plate 32, which is inclined outward. After the side baffle 29 is flipped, the inner wall surface of the diagonal support plate 32 can block the side of the side baffle 29 to further limit the flipping angle of the side baffle 29. At the same time, the inclined diagonal support plate 32 can support the side of the inclined material box, improving the stability of the material box during the inclined conveying process.

[0056] like Figure 1 As shown, in some embodiments, the side of the inclined support plate 32 facing the flip-up conveyor mechanism 2 of the present invention is at a 45-degree angle to the vertical line. Therefore, when the material box is supported by the inclined support plate 32, the opening of the material box is also at a 45-degree angle, which facilitates the sorting personnel to sort the materials in the material box. When the flip angle of the material box is less than 45 degrees, the opening of the material box is too high, making it inconvenient for the sorting personnel to sort the materials in the material box. When the flip angle of the material box is greater than 45 degrees, the materials in the material box will tilt and accumulate excessively in the direction of the limiting mechanism 3, which will cause the material box to easily tip over.

[0057] like Figure 8 As shown, in some embodiments, a damping device is provided in the gap between the second conveying roller connecting frame 211 and the anti-wear rotating roller 2111 of the present invention. The damping device includes an elastic damping plate 2112. An electromagnet 2113 is provided on the side of the damping plate 2112 facing the second conveying roller connecting frame 211, and a permanent magnet 2114 is provided on the other side of the damping plate 2112.

[0058] When the electromagnet 2113 is energized, it can attract or repel the permanent magnet 2114. When the electromagnet 2113 attracts the permanent magnet 2114, the permanent magnet 2114 separates from the anti-wear roller 2111, and the anti-wear roller 2111 can rotate freely. When the electromagnet 2113 and the permanent magnet 2114 repel each other, the permanent magnet 2114 will come into contact with the surface of the anti-wear roller 2111. As the repulsive force increases, the friction gradually increases, thereby changing the rotation speed of the anti-wear roller 2111 in this group, and thus changing the conveying speed of the material box on the flip-over conveyor mechanism 2 in this group, so as to further facilitate sorting, while the material boxes on the other groups of flip-over conveyor mechanisms 2 are conveyed normally.

[0059] In summary, in the GTP goods-to-person system of the present invention, during the normal transport of material boxes, the material conveying roller 212 is horizontal with the horizontal conveying mechanism 1. When sorting is required, the GTP system controls the corresponding position of the flipping motor 23 to drive the drive rod 24 to flip, so that the opening of the material box faces the sorting personnel, so as to facilitate the sorting personnel to pick up and place the goods. The side baffle 29 returns to the horizontal state after the goods are sorted and continues to transport. The single-layer conveying flipping mode realizes efficient transport and sorting, and allows sorting personnel to operate without bending over, reducing labor consumption.

[0060] This invention designs the top of the second conveyor roller connecting frame 211 to be higher than the top of the side baffle 29, so that after the side baffle 29 is flipped, the material box can be supported by the second conveyor roller connecting frame 211 to prevent the material box from sliding. At the same time, an anti-wear roller 2111 is provided on the side of the second conveyor roller connecting frame 211 facing the material conveying roller 212. The anti-wear roller 2111 can effectively reduce the friction between the material box and the second conveyor roller connecting frame 211, so that the material box can continue to be conveyed after it is flipped, further improving the sorting efficiency.

[0061] This invention provides a flipping limiting frame 27 on the side of the support frame 21, and the guide groove 28 on the flipping limiting frame 27 cooperates with the limiting guide rod 292 on the inner wall of the side baffle 29 to limit the maximum flipping angle of the side baffle 29, which can effectively prevent the material in the material box from falling out of the material box. At the same time, a protective frame 31 is provided on the side of the horizontal conveying mechanism 1 and the flippable conveying mechanism 2, and a diagonal support plate 32 is provided on the top of the protective frame 31. After the side baffle 29 flips, the diagonal support plate 32 can further limit the flipping angle of the side baffle 29, and can further support the material box through the diagonal support plate 32, thereby achieving the effect of further improving the conveying stability.

[0062] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0063] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
