Description

Technical Field

[0001] The invention belongs to the technical field of sorting devices, and in particular relates to an unmanned warehouse cargo sorting operation device. Background Art

[0002] Unmanned warehouse cargo sorting is the process of classifying and organizing the cargo in the warehouse by using automation technology and equipment; the whole sorting system mainly consists of identification system, control system and sorting system; the automation equipment in unmanned sorting can complete the sorting task quickly and accurately, with high sorting speed and accuracy, and can improve the utilization rate of storage space and reduce the warehouse floor space by optimizing cargo storage and sorting layout; the data management system can record the detailed information and sorting process of the cargo, which is convenient for cargo traceability and quality control; the identification system and control system technology are almost mature, and the sorting system needs to be selected according to different needs.

[0003] At present, the common sorting types on the market include tray sorting, slider sorting and cross sorting. Among them, slider sorting is to set a slider that can slide horizontally on the slide of the conveyor. When the goods arrive at the designated position, the slider pushes the goods to slide to the corresponding discharge port. Cross sorting is a sorting system composed of a series of small belt conveyors. The goods are placed on the cross belt. Through computer control, the cross belt can accurately transport the goods to the designated discharge port.

[0004] In the sorting of warehouse goods, the main method is flip tray sorting. The flip tray sorting can be simply understood as placing the goods on the flip tray. Through the command of the control system, the flip tray can be turned over to pour the goods into the designated discharge port or conveyor line. The common flip tray adopts one-way deflection sorting, which can only sort the goods with the same information. At the same time, during one-way sorting, the goods are easy to be piled up at one exit, which can easily cause the exit to be blocked.

[0005] Therefore, it is necessary to provide an unmanned warehouse cargo sorting operation device to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an unmanned warehouse cargo sorting operation device.

[0007] This unmanned warehouse cargo sorting operation device is provided with a cargo feeding conveyor, a turning plate assembly and a cargo discharging conveyor in sequence along the longitudinal direction, and the turning plate assembly is used for horizontal bidirectional sorting of the cargo;

[0008] The flap assembly includes a flap part, a bearing shaft and a support frame. The two bearing shafts are respectively arranged below the two lateral sides of the flap part, the support frame is installed between the two bearing shafts, and the flap part is installed at the top of the center of the support frame; when the bearing shaft rotates, the flap part flips horizontally;

[0009] A conveyor belt is laterally sleeved on the surface of the turnover part, and a synchronous belt is sleeved between the two load-bearing shafts. The synchronous belt is connected to the bottom surface of the conveyor belt through a synchronous rope to control the rotation of the conveyor belt.

[0010] Preferably, driving gears are provided at both ends of the load-bearing shaft, a driving rod is provided between the two load-bearing shafts, driving racks are connected at both ends of the driving rod, the driving racks and the driving gears are meshingly connected, and the driving rod is connected to a hydraulic push rod. The driving rod is used to control the lateral translation of the driving rod and drive the load-bearing shaft to rotate.

[0011] Preferably, a cylinder is rotatably mounted on the bearing shaft, a gear plate and an annular tooth block are provided on the cylinder, a driving rack is fixedly connected with a linkage rack, the linkage rack and the annular tooth block are meshed and connected, and a synchronous belt is sleeved on the gear plate.

[0012] Preferably, a support plate is fixedly connected to the bottom of the synchronous belt, the bottom end of the synchronous rope is fixed to the support plate, and the top end is fixed to the bottom of the conveyor belt.

[0013] Preferably, balls are distributed on the surface of the conveyor belt.

[0014] The method for using the unmanned warehouse cargo sorting operation device comprises the following steps:

[0015] Step 1: With the cargo conveying direction as the longitudinal direction, install the cargo feed conveyor, the tilting assembly and the cargo discharge conveyor in sequence, and the tilting assembly is arranged horizontally; install the scanning module and the control system on the cargo feed conveyor; and arrange sorting baskets of two types of cargo on both sides of the tilting assembly in the horizontal direction;

[0016] Step 2: The cargo feeding conveyor conveys the cargo to the front of the tilting assembly, and the scanning module distinguishes the cargo type;

[0017] Step 3: The goods are moved onto the conveyor belt. When the goods are one of the two types of goods, the control system controls the load-bearing shaft and the synchronous belt to rotate, the flip table flips to the lateral side, the synchronous rope pulls the conveyor belt to rotate, and the goods fall from the lateral side of the flip table to the sorting basket.

[0018] Preferably, adjacent turntable assemblies and cargo discharge conveyors form a sorting unit, and a plurality of sorting units are provided in the sorting operation device according to the number of cargo types that need to be distinguished.

[0019] The beneficial effects of the present invention are:

[0020] 1) The present invention sets a turning plate part on the top of the turning plate assembly, and the turning plate part can be controlled to deflect to both sides laterally by a load-bearing shaft rod. When sorting the stored goods, the deflection direction of the turning plate assembly can be changed by controlling the extension and contraction amount of the hydraulic push rod. When the turning plate part is inclined relative to the horizontal plane, the goods slide on the conveyor belt, thereby realizing a two-way deflection sorting effect of the turning plate part, meeting the sorting requirements of goods with different information, and effectively avoiding the situation where goods are piled up due to unidirectional sorting.

[0021] 2) A conveyor belt is laterally arranged on the surface of the turnover part of the present invention. When the sorting operation is carried out, the turnover part is deflected and the synchronous belt pulls the bottom surface of the conveyor belt to rotate synchronously, so that the goods can automatically slide down the deflected inclined surface to prevent the situation that the friction on the surface of the goods is too large and the goods cannot be separated by themselves, thereby further accelerating the separation speed of the goods. The active rotation method can meet the sorting needs of different goods and has higher applicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with embodiments. The description of the following embodiments is only used to help understand the present invention. It should be noted that for ordinary persons in the art, without departing from the principle of the present invention, the present invention can also be modified in some ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

[0033] Embodiment 1

[0034] As an example, Figure 1 As shown, this unmanned warehouse cargo sorting operation device includes a cargo feed conveyor 1 and a cargo discharge conveyor 2, which are arranged longitudinally in a straight line, and a turntable assembly 3 is provided at the arrangement gap between the cargo feed conveyor 1 and the cargo discharge conveyor 2, and the feed conveyor 1 and the cargo discharge conveyor 2 can automatically convey the cargo. The cargo discharge conveyor 2 and the turntable assembly 3 are combined into a sorting unit, and at least one of the sorting units is arranged longitudinally in each unmanned warehouse cargo sorting operation device to perform bidirectional sorting on the cargo.

[0035] A mounting frame 4 is provided on one side of each flip tray assembly 3, and a scanning module 5 for identifying cargo information is horizontally installed on the top of the mounting frame 4. The scanning module 5 is mainly used to scan and obtain cargo information, and the information is not limited to the destination, size, color, etc. Taking one of the sorting units as an example, a single flip tray assembly 3 can sort at most two different types of cargo, and the different types of cargo are sorted to both sides of the flip tray assembly 3.

[0036] The same type of goods can also be sorted to both sides of the sorting unit to effectively avoid the accumulation of goods caused by one-way sorting.

[0037] A control system 6 is installed on the outer wall of the mounting frame 4. The control system 6 includes a central processing module that receives and processes the identification information of the scanning module 5 and a control module that controls the operation of the turning plate assembly 3. The information identified by the scanning module 5 is directly transmitted to the control system 6. The central processing module located in the control system 6 can compare the received information, and when the sorting requirements are met, the signal is transmitted to the control module and an instruction is issued to notify the control module to drive the turning plate assembly 3 to operate, thereby realizing the function of unmanned sorting. The specific system control process of the unmanned sorting will not be described in detail. Please refer to the common unmanned sorting systems on the market for details.

[0038] like Figures 2 to 4 As shown, the tipping plate assembly 3 includes a support plate 31 fixedly connected to the cargo feed conveyor 1 and the cargo discharge conveyor 2, and the tops of the two parallel support plates 31 are symmetrically welded with shaft frames 32, and the tops of the shaft frames 32 are provided with semicircular grooves, and the outer height of the top of the semicircular groove is greater than the inner height, and a load-bearing shaft rod 321 is placed in the shaft frame 32, and both ends of the load-bearing shaft rod 321 are welded with driving gears 33 for connecting the driving device to rotate the load-bearing shaft rod 321.

[0039] A positioning disc 327 is fixedly installed on the outer wall of the load-bearing shaft 321. Both end surfaces of the positioning disc 327 are smooth surfaces, and one end surface of the positioning disc 327 is in contact with the side wall of the shaft frame 32 but not connected. The lateral displacement of the load-bearing shaft 321 is positioned by the contact between the positioning disc 327 and the shaft frame 32, thereby preventing the load-bearing shaft 321 from lateral displacement.

[0040] Blocks 36 are symmetrically welded on both sides of the support plate 31, and holes 361 are symmetrically opened in any block 36. A driving rod 362 is horizontally inserted in the hole 361. A central block 37 and an external block 38 are respectively arranged between the two blocks 36 on the same side and on the outside, and the side walls of the central block 37 and the external block 38 are fixedly connected to the driving rod 362. A driving rack 381 is welded on the top side wall of the external block 38, and the driving rack 381 and the driving gear 33 are a matching structure. A hydraulic push rod 39 is installed on the side wall of one of the blocks 36, and the piston rod end of the hydraulic push rod 39 is connected to the side wall of the central block 37 through a connecting rod.

[0041] A support frame 34 is fixedly installed between the two bearing shafts 321, and a flap portion 35 is installed at the center of the top of the support frame 34. The hydraulic push rod 39 drives the center block 37 horizontally, and the center block 37 drives the two external blocks 38 on the same side to move synchronously through the driving rod 362. At this time, the driving rack 381 at one end moves toward the driving gear 33 and meshes with it, while the driving rack 381 at the other end gradually moves away from the driving gear 33 on the same side. After the driving rack 381 meshes with its adjacent driving gear 33, the driving gear 33 at this location will drive the bearing shaft 321 to rotate in the shaft frame 32, and the flap portion 35 is fixed to the bearing shaft 321 through the support frame 34. When the bearing shaft 321 rotates, the corresponding support frame 34 rotates, so that the flap portion 35 rotates with the bearing shaft 321, that is, the flap portion 35 is tilted and deflected laterally, and the surface of the flap portion 35 is smooth, so that the goods can easily slide from the flap portion 35.

[0042] When the turning plate 35 is deflected to a certain angle, the goods at the top thereof will slide down under the action of their own gravity, thereby achieving a sorting effect.

[0043] Embodiment 2

[0044] As another embodiment, this embodiment 2 proposes a more specific unmanned warehouse cargo sorting operation device based on the embodiment 1, wherein the surface of the turning plate 35 is covered with a conveyor belt 353, and the conveyor belt 353 is driven by a synchronous rope 320:

[0045] like Figure 5 As shown, the flap portion 35 includes a side plate 351, a rotating shaft 352 and a conveyor belt 353. The two side plates 351 are fixedly mounted on the support frame 34 by bolts. The rotating shaft 352 is symmetrically mounted between the two side plates 351 and near the end. The outer walls of the two rotating shafts 352 are sleeved with the conveyor belt 353, and the conveyor belt 353 is arranged horizontally. The inner wall of the side plate 351 is provided with horizontal circular grooves 356 at equal intervals. The two side plates 351 correspond to the two horizontal circular grooves 356 and the inner supporting circular tubes 357 are horizontally placed between them. The outer walls of the inner supporting circular tubes 357 are in contact with the inner walls of the conveyor belt 353. A plurality of inner supporting circular tubes 357 are horizontally placed in the inner cavity of the conveyor belt 353. When the goods are located at the top of the conveyor belt 353, the conveyor belt 353 is not easy to be concave.

[0046] The surface of the conveyor belt 353 is provided with built-in grooves 354 at equal distances along the path direction, and a ball 355 is installed in any built-in groove 354, and the friction between the goods and the conveyor belt 353 is further reduced by the ball 355. The rotation speed of the conveyor belt 353 relative to the two rotating shafts 352 is determined by the extension and retraction speed of the hydraulic push rod 39. Under normal conditions, the driving time of the hydraulic push rod 39 from extension to recovery to the initial state should not be greater than 1.5s to cope with high-frequency sorting needs.

[0047] like Figure 6 and Figure 7 As shown, the outer wall of the bearing shaft 321 is symmetrically mounted with a gear plate 322, a synchronous belt 323 is mounted between the two gear plates 322 in the same vertical plane of the two bearing shafts 321, a support plate 328 is fixedly mounted on the bottom lower end surface of the synchronous belt 323, a synchronous rope 320 is embedded in the top end surface of the support plate 328, and the end of the synchronous rope 320 is fixed to the bottom of the conveyor belt 353, a cylinder 324 is welded concentrically on the side wall of the gear plate 322, and an annular tooth block 325 is arranged on the outer ring of the cylinder 324, and a linkage rack 326 is fixedly mounted on one side of the driving rack 381 through a square tube, and the linkage rack 326 and the annular tooth block 325 are a matching structure. In the initial state, the linkage rack 326 does not contact the annular tooth block 325 until the hydraulic push rod 39 enters the working state, causing the driving rod 362 to translate to the corresponding side.

[0048] There are multiple synchronous ropes 320, and several synchronous ropes 320 are evenly spaced along the surface of the synchronous belt 323. Multiple synchronous ropes 320 can drive the synchronous belt 323 to move at the same time. Damage to a single synchronous belt 323 does not affect the normal operation of the synchronous belt 323. The upper surface of the synchronous belt 323 is parallel to the upper and lower surfaces of the conveyor belt 353, that is, the synchronous rope 320 can pull the synchronous belt 323 in the horizontal direction to reduce the deformation of the synchronous belt 323.

[0049] like Fig. 9 As shown, a sleeve 51 is installed on the outer wall of the load-bearing shaft 321, and a push rod 52 is welded on the outer wall of the sleeve 51 at equal intervals along the circumferential direction. A steel ball 53 is embedded in the end of the push rod 52, and the outer wall of the steel ball 53 abuts against the inner wall of the cylinder 324. When the load-bearing shaft 321 is deflected, the sleeve 51 and the load-bearing shaft 321 rotate relative to each other, and the axial position of the sleeve 51 relative to the load-bearing shaft 321 remains unchanged. The top steel ball 53 of the push rod 52 will roll along the inner wall of the cylinder 324 to provide internal support for the cylinder 324, thereby preventing the cylinder 324 from deforming.

[0050] It should be noted that the parts in this embodiment that are the same or similar to those in the first embodiment can be referenced to each other and will not be described in detail in this application.

[0051] Embodiment 3

[0052] As another embodiment, this embodiment 3 proposes, based on the embodiments 1 and 2, a method for using the unmanned warehouse cargo sorting operation device:

[0053] Step 1. With the cargo conveying direction as the longitudinal direction, install the cargo feed conveyor 1, the tilting plate assembly 3 and the cargo discharge conveyor 2 in sequence, and the tilting plate assembly 3 is arranged horizontally; install the scanning module 5 and the control system 6 on the cargo feed conveyor 1; set sorting baskets of two types of cargo on both sides of the tilting plate assembly 3 in the horizontal direction; the adjacent tilting plate assemblies 3 and the cargo discharge conveyor 2 form a sorting unit, and set several sorting units in the sorting operation device according to the number of cargo types that need to be distinguished.

[0054] Step 2: Before the cargo feed conveyor 1 conveys the cargo to the tipping assembly 3, the scanning module 5 distinguishes the cargo type; when the cargo belongs to one of the two types corresponding to the sorting unit, the conveying speed of the cargo feed conveyor 1 is reduced, so that the cargo gradually slows down and stops after reaching the top of the tipping part 35, and then step 3 is implemented.

[0055] Step 3: The control system 6 controls the bearing shaft 321 and the synchronous belt 323 to rotate, and the turning plate portion 35 turns to the lateral side.

[0056] like Figure 8 As shown, in this embodiment, taking the movement of the driving rod 362 to the left side, i.e., the L direction, as an example, the flap portion 35 descends at one end toward the L direction and rises at the other end toward the R direction. The rotation angle of the driving gear 33 is equally large at any one time. The rotation angle of the driving gear 33 is determined by the extension and retraction amount of the hydraulic push rod 39. The extension and retraction amount of the hydraulic push rod 39 can be accurately controlled by the control system 6. When the flap portion 35 is deflected to a certain angle, the goods at its top position will slide down under the action of its own gravity, thereby achieving the sorting effect. This active rotation method can meet the sorting needs of goods with different shapes and different friction coefficients, and is more applicable.

[0057] The driving racks 381 on the external blocks 38 on both sides rotate the driving gear 33, driving the two bearing shafts 321 to rotate in the N direction. At the same time, the cylinder 324 also rotates in the N direction, and the bottom of the synchronous belt 323 moves in the R direction, driving the support plate 328 and the bottom end of the synchronous rope 320 to move in the R direction, thereby causing the conveyor belt 353 to wrap around the bottom surface of the flip part 35 to move in the R direction, and the conveyor belt 353 on the top of the flip part 35 moves in the L direction, causing the goods on the flip assembly 3 to slide from the upper middle part of the flip part 35 in the L direction and fall into the sorting basket.

[0058] When the goods do not belong to the two types corresponding to the sorting unit, which can be understood as goods not recognized by the scanning module 5, the conveying speed of the goods feed conveyor 1 does not decrease, and may even increase, so that after the goods move from the goods feed conveyor 1 to the tipping assembly 3, since the conveyor belt 353 has a smooth and level surface and is provided with balls 355, the goods further move longitudinally, slide directly to the top of the goods discharge conveyor 2, and are transported to a farther place for sorting by subsequent sorting units or direct drop-off.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
