Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The sorting device can be used for sorting the packages 600 in the field of logistics technology. Logistics is a comprehensive field that encompasses the processes of procurement, packaging, warehousing, transportation, etc., and packages 600 are typically sorted by destination in a package 600 sorting plant prior to shipment. Packages 600 are mixed together in a number of areas of the package 600 prior to sorting, and packages 600 destined for the same province may be sorted from the stack and collected together according to certain criteria, such as province units. Sorting devices may be used to accomplish the above sorting process.

As shown in fig. 1, fig. 1 shows a schematic structural diagram of a sorting apparatus in an embodiment of the present application, which may include a sorting platform 100, wherein the sorting platform 100 is used for conveying unsorted packages 600. The sorting platform 100 is provided with the blanking opening 110, for example, the sorting platform 100 is provided with a plurality of blanking openings 110, so that, according to a certain sorting standard, for example, packages 600 in the same province fall from the same blanking opening 110, and packages 600 in different provinces fall from different blanking openings 110, thereby realizing sorting of the packages 600 in units of provinces.

In one embodiment, the package 600 may be sorted using an AGV robot 500, which 500 itself has mounted electromagnetic guidance and guidance tracks, navigation and positioning capabilities, and package 600 carrying and autonomous processing capabilities. In other embodiments, the AGV robot 500 may also work in the way of identification code and inertial navigation, for example, a plurality of code distance units for the AGV robot 500 to walk are divided on the sorting platform 100, an identification code may be attached to each code distance unit, the identification code may be a two-dimensional code or a barcode, a camera is provided on the AGV robot 500, and when the AGV robot 500 passes through the identification code, the identification code is read to obtain the positioning information. Further, the identification codes may be disposed at the center position of the code distance unit, that is, the identification codes are not continuously disposed, and the position deviation may still occur during the travel of the AGV robot 500 from one identification code to another. For this purpose, the positioning and navigation are carried out by means of inertial navigation, i.e. by means of inertial gyroscopes.

Instead of manually completing the work of sorting packages 600, multiple AGV robots 500 are typically used in combination. The AGV robot 500 moves on the sorting platform 100 with the package 600, and can determine from which of the drop openings 110 the package 600 needs to be dropped according to information such as a bar code on the package 600, and deliver the package 600 to the corresponding drop opening 110, and then pour the package 600 from the drop opening 110 by turning. Continuing to refer to fig. 1, the flexible buffer pipe 200 and the guide chute 300 are installed at the blanking opening 110, specifically, the flexible buffer pipe 200 has a feeding opening 210 and a discharging opening 220, the feeding opening 210 is connected to the blanking opening 110, the discharging opening 220 is connected to the guide chute 300, when the package 600 falls from the blanking opening 110, the package 600 enters the flexible buffer pipe 200 from the feeding opening 210 of the flexible buffer pipe 200, the flexible buffer pipe 200 has flexibility, and the package 600 hits the inner wall of the flexible buffer pipe 200 and forms a buffer in the falling process, so as to prevent the package 600 from being broken. After the package 600 is buffered in the flexible buffer pipe 200, the sliding speed of the package 600 can be reduced, and the package 600 finally slides out of the discharge hole 220 of the flexible buffer pipe 200 at a slower speed and enters the guide chute 300. Because the flexible buffer pipeline 200 is flexible, the discharge hole 220 may swing arbitrarily, after the guide chute 300 is connected to the discharge hole 220, the guide chute 300 can play a role of fixing the discharge hole 220 of the flexible buffer pipeline 200, that is, the guide chute 300 can position the discharge hole 220, so that the packages 600 sliding out of the flexible buffer pipeline 200 can be collected at a uniform position, in some embodiments, the guide chute 300 is further connected to a collection container 400, the collection container 400 may be a collection bag or a collection frame, etc., and the packages 600 enter the collection container 400 for storage after being guided by the guide chute 300.

Further, as shown in fig. 1, the sorting platform 100, the flexible buffer tube 200 and the guide chute 300 of the sorting apparatus are generally arranged from top to bottom, so that the parcel 600 can slide out of the guide chute 300 under the action of gravity after falling from the drop opening 110 without providing any other power for pushing the parcel 600 to move in the flexible buffer tube 200 and the guide chute 300.

As shown in fig. 1, the position of the guide chute 300 can be adjusted in the horizontal direction, for example, the guide chute 300 can be supported on the ground by a support frame 700, and the user can push the guide chute 300 to move in the horizontal direction, so as to adjust the position of the discharging hole 220. Generally, the outlet 220 is not disposed right below the inlet 210, but is disposed offset from the inlet 210 in the horizontal direction, so that the package 600 will usually contact the inner wall of the flexible buffer pipe 200 after falling, rather than directly exit the outlet 220 after falling through the outlet 110. In addition, since the flexible buffer pipe 200 is flexible, the guide chute 300 can be freely moved within a certain range, thereby improving convenience of adjustment.

In one embodiment, the supporting frame 700 is a supporting frame 700 with an adjustable height, and the height between the guide chute 300 and the sorting platform 100 can be adjusted by adjusting the height of the supporting frame 700. This is because the installation space of fire control, illumination and warm and ventilating etc. usually need to be reserved below sorting platform 100 to and the space that personnel operated still usually need to be reserved below sorting platform 100, therefore, sorting platform 100 is usually higher apart from the height on ground, and in some embodiments, sorting platform 100 can reach 2200mm apart from the height on ground, and the height of collecting container 400 can reach 500mm, and then the letter sorting landing difference in height of parcel 600 is 2200mm minus 500mm, and the letter sorting landing height that obtains can reach 1700 mm. After the AGV robot 500 separates the package 600, the package 600 may generate a certain acceleration in the process of sliding down to the collection container 400, and may collide with the guide chute 300, the collection container 400, and the like many times, resulting in damage to the package 600. By setting up as adjustable height's support frame 700, can be according to the nimble height of adjusting support frame 700 of the nature of parcel 600, for example, to some heavy parcels 600 generally heighten support frame 700 to shorten the difference in height of the letter sorting landing of parcel 600, thereby prevent that parcel 600 from being damaged. In addition, in this embodiment, because the height of the supporting frame 700 is adjustable, for the operators with different heights, the height of the supporting frame 700 can be flexibly adjusted according to the needs of the operators on the basis of convenient operation of the operators, so that the sorting device is more in line with ergonomics, and the convenience of operation of the operators is improved.

In one embodiment, as shown in fig. 1, after the AGV robot 500 turns over to drop the package 600 from the material drop opening 110, the package 600 is usually contacted with a fixed area of the inner wall of the flexible buffer pipe 200, so the fixed area may be referred to as a buffer surface 230, since the buffer surface 230 has a large proportion of buffer function, the buffer surface 230 is not easy to be damaged during long-time operation, and therefore the buffer surface 230 may be made of a material different from the surrounding surface to increase the working performance of the buffer surface 230. For example, cushioning surface 230 may be made of an elastic material that not only has some flexibility, but also better cushions package 600. In some special cases, if the package 600 falls down without directly contacting the buffering surface 230, but contacts other positions of the inner wall of the flexible buffering pipeline 200, the flexible buffering pipeline 200 is flexible, so that the package 600 can be buffered through position movement and flexible deformation, and the effect of protecting the package 600 from being damaged by collision can be achieved. In some embodiments, the buffer surface 230 may be made of a rubber material, and other positions of the flexible buffer pipe 200 may be made of cloth. Of course, the entire flexible buffer tube 200 may be made of rubber. In some embodiments, the flexible buffer tube 200 may also be made of various materials, such as PVC, which is a plastic, and a high-strength polyester mesh, which is a flexible material with mesh holes and has high wear resistance, may be disposed at the orifice of the flexible buffer tube 200 for reinforcing the flexible buffer tube 200. The thickness of the flexible buffer pipeline 200 can be 5 mm-10 mm, which not only ensures that the flexible buffer pipeline 200 has enough strength, but also ensures that the flexible buffer pipeline 200 is light enough.

In some embodiments, the cross-section of the flexible buffer tube 200 may be configured as a circle, and it should be understood that the above-mentioned circle is a shape of a cross-section of the flexible buffer tube 200 after being fully supported since the flexible buffer tube 200 is flexible. In some embodiments, the cross-section of the flexible buffer tube 200 may also be square, rectangular, etc. The rectangular cross-section flexible buffer pipe 200 is vertically disposed to include a top surface, a bottom surface and side surfaces, and it should be understood that the buffer surface 230 is generally disposed on the bottom surface of the flexible buffer pipe 200. The buffer surface 230 may be a partial region of the bottom surface, and the buffer surface 230 may also be the entire bottom surface region.

In one embodiment, as shown in FIG. 1, at least the cushioning surface 230 is a multi-fold corrugated structure. The multi-fold corrugated structure is similar to corrugated paper, namely, a plurality of concave-convex grooves and convex strips which are arranged alternately are arranged on the surface of the multi-fold corrugated structure, and the grooves and the convex strips are approximately arranged in parallel. For example, when the package 600 is a cold chain type package 600, the cold chain type includes products to be frozen such as fish, shrimp, etc. which are generally packed inside, and the temperature thereof is low, so that condensed water may be attached to the outer surface of the package 600. When such a package 600 slides in the flexible buffer pipe 200, condensed water may adhere to the inner wall of the flexible buffer pipe 200, thereby increasing the friction of the inner wall, which may cause the package 600 to be stagnated in the flexible buffer pipe 200. And many books flute structure's buffering face 230 has a plurality of unsmooth alternate recesses and sand grip, and when the surface attachment has the parcel 600 of comdenstion water and the 230 contact of buffering face, the sand grip can get up the surface support of parcel 600 to reduce the area of contact of parcel 600 surface and buffering face 230, reduced frictional force, thereby make the gliding in flexible buffer pipeline 200 that parcel 600 can be smooth. In addition, because many books flute structure's buffering face 230 has a plurality of unsmooth alternate recesses and sand grip, when the parcel 600 that the surface adhesion has the comdenstion water slides in flexible buffer pipeline 200, these comdenstion waters can be stored in the recess, when follow-up meeting carton class parcel 600, the sand grip can support parcel 600 for the carton can not contact with the moisture in the recess, prevents that moisture from soaking the carton. In addition, a drain hole can be arranged at the groove of the multi-fold corrugated structure, so that moisture accumulated in the groove can be drained timely.

It should be understood that the buffering surface 230 may also be a structure having a plurality of concave-convex grooves and convex strips, which is different from the above-mentioned embodiment in that the surface of the buffering surface 230 for wrapping with the package 600 is a structure having a plurality of concave-convex grooves and convex strips, and the multi-fold corrugated structure is a structure having a plurality of concave-convex grooves and convex strips on both opposite surfaces of the buffering surface 230. That is to say, in order to make the surface have the parcel 600 of comdenstion water to contact with buffering face 230, the sand grip can support the surface of parcel 600 to reduce the area of contact of parcel 600 surface and buffering face 230, reduced frictional force, only at buffering face 230 be used for with the face of parcel 600 set up the structure of a plurality of unsmooth alternate recesses and sand grips also can. The multi-fold corrugated structure, as shown in fig. 1, is a structure having good tensile and compressive properties, and can conveniently adjust the length and bending direction.

Of course, in some embodiments, the entire flexible buffer tube 200 may also be a multi-fold corrugated structure having a plurality of alternating concave and convex grooves and convex strips. It should be understood that the multi-fold corrugated structure is at least disposed on the inner wall of the flexible buffer pipe 200, and of course, in some embodiments, the multi-fold corrugated structure may also be disposed on the inner wall and the outer wall of the flexible buffer pipe 200. Preferably, the inner wall and the outer wall of the flexible buffer pipeline 200 are both configured as a multi-fold corrugated structure, and the structure has good tensile and compressive properties, so that the length and the position of the flexible buffer pipeline 200 can be conveniently adjusted.

As shown in fig. 2, fig. 2 is a schematic view illustrating an assembly structure of a flexible buffer pipe 200 and a guide chute 300 according to an embodiment. The discharge port 220 of the flexible buffer pipeline 200 is provided with the adsorption rubber ring 260, specifically, the adsorption rubber ring 260 is arranged on the inner wall of the flexible buffer pipeline 200, the guide chute 300 is inserted into the flexible buffer pipeline 200 from the discharge port 220, and the adsorption rubber ring 260 is attached to the outside of the guide chute 300, the friction force between the adsorption rubber ring 260 and the guide chute 300 is large, and the guide chute 300 can be prevented from being separated from the flexible buffer pipeline 200. Further, the discharge hole 220 of the flexible buffer pipe 200 may be bound with a binding tape, further preventing the guide chute 300 from being separated from the flexible buffer pipe 200.

Further, as shown in fig. 2, a fastening assembly 240 is further disposed at the feeding inlet 210 of the flexible buffer pipe 200, specifically, the fastening assembly 240 is disposed at an outer surface of the flexible buffer pipe 200 and near the feeding inlet 210, and the fastening assembly 240 may be fixed on the sorting platform 100 by a bolt 250. Wherein the fastening assembly 240 may be fixed on the outer wall of the flexible buffer pipe 200 along a ring shape.

In the flexible buffer pipe 200 in the above embodiment, the adsorption rubber ring 260 is disposed at the discharge port 220, and the flexible buffer pipe 200 is bound to the guide chute 300 by a tie; and a fastening assembly 240 is provided at the feeding inlet 210 and the flexible buffer pipe 200 is fixed to the sorting platform 100 by bolts 250. Above-mentioned structure is detachable construction, if when needing to be changed, the dismantlement and the reinstallation of realization flexible buffer pipeline 200 that can be convenient and guide spout 300 and letter sorting platform 100 improve easy operation conveniently.

As shown in fig. 1, after passing through the flexible buffer pipe 200, the package 600 enters the guide chute 300 through the discharge hole 220, and enters the collection container 400 under the guidance of the guide chute 300. The speed of the parcel 600 has been reduced by the parcel 600 passing through the flexible buffer duct 200, and after the parcel 600 enters the guide chute 300, in order not to further increase the speed at which the parcel 600 slides, it is necessary to control the slope of the guide chute 300, that is, to make the chute surface in the guide chute 300, which is the surface for guiding the downward movement of the parcel 600 in the guide chute 300, gently slide down. In some embodiments, the included angle α between the tangential direction of the chute surface of the guiding chute 300 and the horizontal direction is 27 ° to 30 °, and tests show that the package 600 can smoothly slide down within the angle range, and the package 600 can be ensured not to slide down too fast.

In some embodiments, the chute face in the guide chute 300 may be helical, i.e. the chute face extends downwardly in a helical trajectory. Specifically, spiral spout face can adopt stamping forming technique to make and form, and more traditional straight spout that forms through the multistage concatenation, the spout face of spiral spout is excessive more steady, does not have the corner and the slope of sudden change, and is more steady when parcel 600 glides along spiral spout face. Of course, in some embodiments, the guide chute 300 may be a single-segment straight chute.
