Detailed Description

Objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments. These embodiments are merely exemplary embodiments for applying the technical solutions of the present invention, and all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.

In the description of the embodiments, it should be noted that the terms "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the embodiment, the operator is used as a reference, and the direction close to the operator is a proximal end, and the direction away from the operator is a distal end.

The following explains the sorting apparatus with multi-layer routing according to the present invention with reference to the accompanying drawings, as shown in fig. 1, the apparatus includes at least one sorting machine 100, the sorting machine 100 is disposed in a carousel-type rotating apparatus 200 for driving the sorting machine to revolve around an axis, at least one sorting machine 100 is connected to the carousel-type rotating apparatus 200 through a height-adjusting apparatus 300 for adjusting the height of the conveying surface thereof, and an adapter 400 with multi-layer space is disposed at the periphery of the rotating track of the outer end of the sorting machine 100.

In operation, articles with determined routes are placed on the sorting machine 100, the turntable-type rotating device 200 drives the sorting machine 100 to rotate, in the rotating process, the height of the sorting machine 100 is adjusted by the height adjusting device 300 according to a corresponding space of a layer of the transferring device 400 to which the goods are to be sorted, and the articles on the transferring device 400 are conveyed to the corresponding space of the layer after the sorting machine 100 rotates to the corresponding transferring device 400. Subsequently, the height-adjusting means 300 adjusts the sorter 100 to the upper deck height, and at the same time, the carousel-type rotating means 200 drives the sorter 100 to rotate again to the upper deck position for the upper deck.

In one embodiment, the sorter 100 may be one, and in this case, it is inefficient to sort again only when the sorter 100 moves to the upper package position again after sorting a piece of goods. Therefore, in a more preferred embodiment, as shown in fig. 1, there are a plurality of sorting machines 100, for example, there are 4 sorting machines 100, or there are more sorting machines 100 distributed in a circular ring shape, the width-direction symmetry axis of their conveying surfaces passes through the center of the circle they enclose, and two adjacent sorting machines 100 can maintain a gap, and more preferably, the inner ends of two adjacent sorting machines 100 are close to each other, and the outer ends are maintained at a certain distance.

The sorter 100 may be any of a variety of known devices having the ability to carry and move other items, such as a belt conveyor, a powered roller conveyor, a flap sorter, etc., or the sorter 100 may have a platform on which the objects are placed, with a pushing mechanism disposed at an inner end of the platform that applies a pushing force to the items on the platform to move them out of the platform from an outer end of the platform. In the preferred embodiment, the sorter 100 is a belt conveyor, which is more advantageous for sorting light and thin pieces.

A group of the sorting machines 100 can be driven to revolve around the central axis of the circle formed by the two machines by various structures, for example, as shown in fig. 2, the rotating disc type rotating device 200 includes a disc 210, but the disc 210 can also be a divergent bracket, the bottom of the disc 210 is coaxially connected with a transmission shaft 220, the transmission shaft 220 is rotatably arranged on a supporting table 230, and the transmission shaft 220 is connected with a speed reducing motor 240. Of course, the transmission shaft 220 may also be connected to a motor fixed on the support platform 230 through a transmission structure formed by a timing belt and a timing wheel or a gear.

And, in order to increase the supporting strength of the disc 210 or the divergent bracket, a plurality of reinforcing members (not shown in the drawings) are further provided between the bottom of the disc 210 or the divergent bracket and the sidewall of the driving shaft 220.

In practical design, part of the sorting machine 100 can be lifted or lowered as required, or all the sorting machines 100 can be lifted or lowered, and the lifting or lowering of each sorting machine 100 is realized by an independent height-adjusting device 300.

The height-adjusting device 300 can be various devices capable of generating linear movement, for example, the height-adjusting device 300 is a non-inductive air cylinder, an electric push rod, an oil cylinder, and the like. Taking the electric push rods as an example, each electric push rod may be disposed on the disc 210 at a position close to the edge, and the telescopic shaft of the electric push rod extends downward from the upper portion of the disc 210 to the lower portion thereof, at this time, the telescopic shaft of each electric push rod may be connected to the tail end of the sorting machine 100 or connected to the side portion of the sorting machine 100.

Of course, in another embodiment, the electric push rod may be disposed at the bottom of the sorting machine 100, and the electric push rod drives the sorting machine 100 to move by jacking.

However, in both of the above-described modes, when a large height adjustment stroke needs to be satisfied, the height adjusting means 300 needs to be increased in size, which increases the load of the disc 210 and the installation space required therefor, which is obviously disadvantageous.

Thus, in a more preferred embodiment, as shown in fig. 2, each of the height-adjusting devices 300 includes a motor 310 disposed on the disc 210 of the carousel-type rotating device 200, the motor 310 is close to the edge of the disc 210 and the motor shaft thereof passes from above the disc 210 to below the disc 210, the motor shaft of the motor 310 is connected to the lead screw of the lead screw 320 perpendicular to the conveying surface of the sorter, the lower end of the lead screw 320 is rotatably disposed on a support frame 330 fixed on the disc 210 and extending to the end of the lead screw, the support frame 330 is used for supporting the lead screw 320, that is, a bearing 340 coaxial with the lead screw 320 is disposed at the bottom of the support frame 330, the lower end of the lead screw is fixed on the bearing 340, and the movable block of the lead screw 320 is connected to the sorter 100.

In the above structure, the height-adjusting device 300 is often connected only to the rear end or the side of the sorting machine, and since each sorting machine 100 has a certain mass, if only one point has a support, the whole sorting machine 100 lacks the support, and the inclination condition is easy to occur, which affects the stability of the upper package and the stability of the articles on the sorting machine 100.

Therefore, in order to ensure that the conveying surface of the sorting machine 100 is kept horizontal, as shown in fig. 1 and fig. 3, each sorting machine 100 is arranged on a support 500, the support 500 is connected with the height-adjusting device 300, the support 500 specifically comprises a top plate 510, an inner end of the top plate 510 is connected with a slant plate 520, the slant plate 520 is connected with a vertical plate 530 perpendicular to the top plate 510, and the vertical plate 530 is connected with a movable block of the screw 320. In addition, in order to increase the rigidity of the top plate 510, the inclined plate 520 and the vertical plate 530, reinforcing plates 540 perpendicular to the top plate 510, the inclined plate 520 and the vertical plate 530 are disposed on both sides of the top plate 510, the inclined plate 520 and the vertical plate 530, and the reinforcing plates 540 on the same side are integrated or connected together. Of course, in other embodiments, a plurality of sloping plates may be added between the fixed plate 510 and the vertical plate 530 to increase the rigidity of the whole structure.

More preferably, as shown in fig. 3, the vertical plate 530 is connected to a U-shaped member 550, and the U-shaped member 550 is also connected to the movable block of the lead screw. The U-shaped member 550 is further connected to a sliding member 560, the sliding member 560 is slidably disposed on the supporting frame 330, for example, the sliding member 560 is a linear bearing, a cylinder perpendicular to the top plate 510 is disposed on the supporting frame 330, and the linear bearing is sleeved on the cylinder. Therefore, the support can be effectively provided by the support 500 and the support frame 330, and the stability of the whole structure is ensured.

In addition, since the supporting frame 330 is to rotate along with the disk 210, the lower end thereof cannot be fixed, and the supporting strength of the supporting frame 330 is insufficient due to only the upper end thereof being fixed, it is preferable that the bottom of the supporting frame 330 has a certain support. Preferably, the support bracket 330 is in rolling engagement with the mounting base 600. That is, rollers or universal balls (not shown), preferably, eyeball universal balls, are mounted at the bottom of the supporting frame 330, and the rollers or universal balls are located on the mounting base 600, so that the mounting base can effectively support the supporting frame 330, and the rollers and the universal balls do not interfere with the normal rotation of the supporting frame 330.

The transferring device 400 may be one or a plurality of transferring devices 400, and the transferring device 400 may be configured in different structures according to different applications, in a feasible manner, as shown in fig. 4, the transferring device 400 may be a plurality of layers of sorting compartments, each sorting compartment includes a slope 430, the extension length of the plurality of layers of slopes 430 gradually increases as the number of layers of the slope increases, the lower end of the slope of each layer of sorting compartment may be provided with a receiving container 440, such as a bag, a frame, a bucket, or the like, and the receiving containers connected by the plurality of layers of slopes are staggered. And, the plurality of the transferring devices 400 are annularly enclosed at the periphery of the sorting machine.

Of course, in another possible embodiment, as shown in fig. 1, the transferring device 400 may be a plurality of transferring cabinets enclosing a structure having a plurality of rows and columns of receiving cells 410 and arranged around a group of the sorting machines 100. In addition, a plurality of the transfer devices 400 are not enclosed in a closed loop for transporting articles to the sorter 100.

Further, the width of each storage compartment 410 is larger than the width of the conveying surface of the sorter 100, and the panel 420 of each storage compartment 410, which is opposite to the sorter 100, has a door structure that can be opened and closed, so that the articles in the storage compartment 410 can be conveniently taken out when necessary. And, the lock structure of door can be the structure or the manual lock structure that electronic was opened, and the lock structure that electronic was opened can refer to the automatically-controlled door structure of intelligent express delivery cabinet. When an automatic door opening structure is adopted, when the door for accommodating the grids is opened, the door can be opened through a control button (not shown in the figure) corresponding to each door, and all the accommodating grids 410 can be controlled through a set of control system close to the intelligent express cabinet in a pickup way. When specifically picking, the worker needs to input information of the picked articles on the control panel, the information at least comprises names and the number of the articles, the system automatically opens the door of the accommodating grid 410 where the article corresponding to the information is located according to the input information, the door is closed after the worker picks the articles, the system automatically updates the article stock, and of course, the system can also signal the sorting machine 100 to supplement the articles corresponding to the accommodating grid 410 through the upper computer.

In the above structure, to realize sorting, the articles are firstly placed on each sorting machine 100, and in a feasible manner, a manual wrapping manner may be adopted, for example, after a package is manually placed on the sorting machine 100, the code scanning device located behind the wrapping point acquires the routing information, and controls the actions of the sorting machine and the height adjusting device after the routing is acquired.

In a preferred mode, an automatic package feeding structure is adopted, as shown in fig. 5 and fig. 6, for example, a known package feeding table 700 is adopted for feeding packages, and the package feeding table may be a DWS package feeding line, which has functions of weighing, code scanning, volume measurement and the like, specifically is a known technology, and is not a midpoint of the scheme, and details are not described here. Since the transfer device 400 has multiple layers of spaces, each sorting machine 100 needs to be switched between different positions, and in order to improve the efficiency of each sorting machine, the height of the upper package of the position of the package supply table 700 is preferably set in the middle height area of the transfer device, so that after the upper package of the sorting machine, the distance from the upper layer space or the lower layer space to the upper layer space is shorter, and the distance from the lower layer space to the upper package height again is shortest, thereby improving the efficiency and facilitating the distance between the package supply table 700 and two adjacent transfer devices to be smaller.

In a more preferred embodiment, the packing position of the packing table 700 satisfies T_{Rotate min}＞T_{High max}Wherein, T_{Rotate min}The time required for the sorter 100 to move from the upper packing position to the first transfer device 400 or the time required for the last transfer device 400 to move to the upper packing position; t is_{Height of}The time for the sorter 100 to move from the upper package level to the maximum lower package level or the time for the maximum lower package level to the upper package level.

Further, in the sorting system with multi-layer routing, as shown in fig. 6, the output end of the packet supply platform 700 is provided with a transfer device 800, and each layer of the switching device 400 is provided with a storage remaining amount detection device (not shown). The transfer device 800 may be, for example, a swing arm machine located on the side of the output end region of the feeding table 700, or a deflecting wheel/ball sorter coupled between the feeding table 700 and the sorter 100. The storage allowance detection device is used for determining whether each layer of space of the transfer device 400 has the capability of continuously receiving the articles conveyed by the sorting machine 100, and the storage allowance detection device can be a proximity sensor or a distance measuring sensor, such as a laser distance meter, arranged at the top of each layer of accommodating grid 410. When the proximity sensor is triggered or the distance measured by the distance measuring sensor reaches a predetermined threshold value, the storage compartment 410 cannot be loaded with any more items. At this time, when the supply table 700 determines that the storage compartment 410 in which the article cannot be stored any more is routed, the transfer device 800 may remove the article without transferring the article to the sorter 100. Of course, the transfer device 800 may be omitted, and when it is confirmed that the storage compartments 410 corresponding to the articles are full, the control system may generate an alarm signal to prompt the operator to perform the process and the sorting machine 100 may not operate.

The scheme further discloses a sorting method of the sorting device with the multilayer routing, which comprises the following steps:

items are placed onto the bagging station either manually or by automated equipment.

And S1, conveying the articles on the bag supply table, and acquiring information such as article routing and weight by devices such as code scanning and weighing at the bag supply table to an upper computer.

And S2, the upper computer determines the switching device 400 corresponding to the article route, the layer number in the switching device, the reservation trolley and the control packet supply platform to supply packets according to the calculated parameters.

And S3, conveying the articles to a preset sorting machine 100 by the wrapping table, enabling the articles to rotate along with the sorting machine 100 after entering the sorting machine 100, and simultaneously starting a motor of the height adjusting device to drive the sorting machine to move from the upper wrapping height to the lower wrapping height.

And S4, when the sorting machine moves to the corresponding switching device 400, the sorting machine 100 is started to sort, and the height-adjusting device drives the sorting machine to move to the height of the upper package and then to load the upper package.

Of course, when the above-described process is performed, the mounting position of the supply stand 700 is such that T is satisfied_{Rotate min}＞T_{High max}And the accommodating grids corresponding to the article routes still have accommodating spaces.

In addition, in the sorting process, the lower package position of each layer of space of the sorting machine can be the maximum allowable height of the corresponding layer of the article, so that the height of the existing article in the accommodating grid can be not considered. In another embodiment, the height of the existing article in the storage compartment 410 may be determined by a distance measuring sensor, and then the height of the lower bag of the sorting machine 100 may be controlled to a position slightly higher than the height of the existing article in the storage compartment. The sorting method is particularly suitable for sorting thinner objects, such as clothes, documents, letters and the like.

The scheme further discloses another sorting method of the sorting device with the multilayer routing, which comprises the following steps:

s10, the bag-packing table obtains the article route to the upper computer;

s20, the upper computer determines the switching device corresponding to the article route and the layer number in the switching device, and calculates the time T required for the article to move from the upper package position to the corresponding switching device_{Rotating shaft}And the time T required for the sorting machine to move from the upper package height to the lower package height_{Height of}；

S30, judging T_{Rotating shaft}And T_{Height of}Of size, e.g. T_{Rotating shaft}＞T_{Height of}I.e., the sorter is adjusted in height by sufficient time to enable the articles thereon to be sorted to the corresponding height of the compartments or storage spaces, S4 is performed, e.g., T_{Rotating shaft}≤T_{Height of}That is, the sorting machine does not have enough time to adjust the height of the lower package, and needs to rotate one more turn to adjust the sorting machine to the height of the lower package, S5 is executed;

s40, the packing table conveys the articles to a preset sorting machine, and the articles rotate along with the sorting machine and are adjusted in height after entering the sorting machine; the sorting machine rotates to the corresponding switching device to carry out transferring;

s50, the packing table conveys the articles to a preset sorting machine, and the articles rotate along with the sorting machine and are adjusted in height after entering the sorting machine; and the sorting machine moves to the corresponding transfer position for the second time to carry out transfer.

The overall process of the method is similar to the process of S1-S4 described above, with the difference that: at this time, the wrapping position of the wrapping table 700 is not specially designed, i.e. T is not satisfied_{Rotate min}＞T_{High max}But rather makes up for the lack of distance by controlling the lower package practice of the sorter 100.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
