Some embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. The embodiments described below and features in the embodiments may be combined with each other without conflict.

In some technologies, the sorting equipment includes a feeding device and a sorting machine, and the goods are conveyed to the sorting machine through the feeding device. Sorter, also known as sorting conveyor, is a special conveying equipment used for product sorting and conveying. Currently, there are many types of sorters, such as circular sorters (aka circular seeders). The running speed of the circular sorter is 3000-3600 beats/hour. If the running speed of the circular sorter is further increased, the existing feeding device will not be able to match it well.

The specific reasons for the above problems are: the linear speed of the circular sorting machine mainly depends on the width of the trolley on the circular sorting machine and the feeding time of the feeding device; the feeding time of the feeding device depends on the circular sorting machine. The feed rate of the picker. If the feeding speed of the feeding device is higher, the kinetic energy of the goods when they enter the sorting station of the circular sorter will be greater, and the larger kinetic energy will lead to a longer delivery distance of the goods. Therefore, under the premise of a certain delivery distance of the goods, it is not feasible to simply increase the feeding speed of the feeding device.

In order to alleviate the above-mentioned defects, the inventor has developed a sorting device, which can improve the efficiency of goods delivery and alleviate the technical problem of low sorting efficiency of the sorting device in the prior art by realizing co-directional feeding. Next, the structure of the sorting device will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 to 3 , this embodiment provides a sorting device, the sorting device includes a feeding device 100 and a sorting device 200 , the feeding device 100 includes a feeding main line 110 , and the sorting device 200 includes a sorting device The main line 210, the main feeding line 110 is used for conveying the goods to the main sorting line 210, and the main sorting line 210 is used for conveying the goods to the set position; The conveying direction of the material end is the same.

In the sorting device provided in this embodiment, since the conveying direction of the discharging end of the main feeding line 110 is the same as the conveying direction of the feeding end of the main sorting line 210 , the discharging end of the main feeding line 110 and the incoming end of the main sorting line 210 are the same. The relative speed of the material end will be lower than when the above two are crossed, opposed or opposed to each other. Therefore, the feeding speed of the main feeding line 110 can be appropriately increased, so that the feeding frequency of the main feeding line 110 in the same time period can be increased, and then To improve the delivery efficiency of goods, correspondingly, the sorting speed of the sorting main line 210 can be appropriately increased. The relative speed of the two remains the same as before the speed increase, or is slightly higher than that before the speed increase, so as to ensure that the goods on the main feeding line 110 can enter the main sorting line 210 normally.

It should be noted that, in some technologies, the main feeding line 110 and the main sorting line 210 are arranged at an included angle (or intersected), and the included angle is designed to be an acute angle or a right angle. Taking the included angle set to 90° as an example, specifically, the goods on the main feeding line 110 have a first speed before they are transferred to the main sorting line 210 (the first speed is the same as the speed of the main feeding line 110), and the goods are transferred to the sorting line 210. The main line 210 has a second speed (the second speed is consistent with the speed of the sorting main line 210). Since the first speed and the second speed are perpendicular to each other, the first speed and the second speed cannot cancel each other, so the first speed and The value of the relative speed of the second speed (the relative speed can also be understood as the relative movement speed of the feeding main line 110 and the sorting main line 210) can be regarded as the first speed of the goods, if the first speed is set If the value is too large, the goods will have large kinetic energy when they are transferred to the main sorting line 210, which is not conducive to the control of the feeding distance of the goods.

In the sorting apparatus, referring to FIG. 3 , FIG. 4 or FIG. 5 , the sorting device 200 includes a sorting mechanism 220 , and the sorting mechanism 220 includes a plurality of sorting stations 221 and a Driving mechanism; a plurality of sorting stations 221 are arranged at intervals along the main sorting line 210 and can move along the main sorting line 210 under the driving of the driving mechanism; the discharge end of the main feeding line 110 can be separated from one of the main sorting lines 210 The sorting station 221 corresponds to the sorting station 221 , so that the goods are transferred from the discharge end of the main feeding line 110 to the sorting station 221 . According to the layout form of the sorting main line 210, a matching driving mechanism is selected, which is clear to those skilled in the art, and the specific structural form of the driving mechanism is not repeated here.

It should be noted that the main sorting line 210 can be understood as multiple meanings, including linear structures such as rails or conveyor belts that can be arranged for the sorting stations 221 .

Taking into account the overall layout of the equipment and the sorting efficiency, the sorting main line 210 can be set in a linear shape or a curved shape, such as L-shaped, U-shaped, linear, etc. Of course, it can also be set as a closed loop, such as a circle shape, rectangle or other irregular closed loop. Compared with the open linear structure, the closed rotary circulation structure can realize the continuous circulation and flow sorting of the goods, maintain the continuous movement state, avoid the parking of the goods, improve the sorting efficiency, and save the installation space of the equipment.

In this embodiment, the sorting mechanism 220 may have the following structural forms.

Wherein, the position of the first container can be fixed relative to the ground.

Specifically, considering the automatic sorting of the sorting equipment, each sorting station 221 is provided with a first detection element (not shown in the drawings). Wherein, both the first detection element and the sorting and conveying assembly are controlled by a control device (eg, PLC). The first detection element of each sorting station 221 is bound to a first container, and the function of the first detection element is that when the goods are transferred to one of the sorting stations 221, the first detection element can detect The identification information on the goods (such as barcode information, two-dimensional code information or RFID tags, etc.), and the detected information is sent to the control device, and the control device receives the information and matches a first corresponding to the goods. Containers. When the sorting station 221 moves to the corresponding position of the first container, the sorting and conveying components on the sorting station 221 send the goods into the first container to complete the sorting of a piece of goods.

For example, the sorting mechanism 220 has 20 sorting stations 221 , wherein each sorting station 221 corresponds to one first container respectively; it is assumed that each sorting station 221 corresponds to a specific sorting station Position, define a number for each sorting position. For example, according to the running track of the sorting mechanism 220, the numbering is No. 1 position, No. 2 position ... No. 20 position. Picking station 221 corresponds to No. 1 position.

Further, the sorting device is also provided with a second detection element (such as a photoelectric switch), which is used to detect in real time whether the sorting station 221 corresponding to the No. There are goods. When one of the sorting stations 221 moves to the No. 1 position, the second detection element detects the sorting station 221, and sends the detection result information to the control device, and the control device realizes the overall control of the entire equipment.

It should be noted that the respective working principles of the first detection element, the second detection element, the sorting and conveying assembly and the control device and the principles of working together with each other are well known to those skilled in the art, and will not be omitted here. Describe in detail.

The staff puts the goods on the main feeding line 110 according to the actual operation requirements, and transports them to the main sorting line 210 through the main feeding line 110 in an orderly manner; when the second detection element detects that the sorting station 221 corresponding to the No. 1 position has no When there are goods, the main feeding line 110 is controlled by the control device to start, and the goods are delivered to the sorting station 221; when the second detection element detects that there is goods on the sorting station 221 corresponding to position 1, the control device controls the supply. The main line 110 stops running; when the goods arrive at a certain sorting station 221, the goods conveyed to the sorting station 221 move with the sorting mechanism 220, and when the goods are sent to the corresponding first container , the sorting and conveying components on the sorting station 221 send the goods to the corresponding first container.

In some embodiments, the sorting and conveying assembly is any conveying assembly among non-partition conveyor belts, partition conveyor belts, conveying rollers, tipping trays, and tipping buckets, as long as the goods can be conveyed to the first It can be placed in a container, and the specific implementation method is not limited.

2) The second structural form of the sorting mechanism 220 is: the sorting mechanism 220 of this structural form is the same as the sorting mechanism 220 of the first structural form described above in that each sorting station 221 is provided with a A first detection element, the sorting device is also provided with a second detection element, wherein the first detection element and the second detection element are both controlled by the control device; the difference is that, in conjunction with FIG. 2 and FIG. A plurality of second containers 230 are arranged below the sorting mechanism 220 in the form, each sorting station 221 is correspondingly arranged with the plurality of second containers 230, and each sorting station 221 has one or more outlet containers 230. and a plurality of second containers 230 corresponding to each sorting station 221 are used for accommodating goods delivered through one or more discharge ports.

In order to improve the sorting efficiency of goods, so that different second containers 230 correspond to the sorting stations 221 , as shown in FIG. 2 , a container conveyor for moving the second containers 230 is added in this embodiment. 240, a container conveyor 240 may be arranged below each sorting station 221.

Specifically, referring to FIG. 2 , the container conveyor 240 includes a reciprocating conveying mechanism and a carrying platform. The reciprocating conveying mechanism has the ability to reciprocate in a straight line, and its output end is drive-connected to the carrying platform for driving the carrying platform to realize linear reciprocating motion. .

As shown in FIG. 3 , FIG. 4 or FIG. 5 , a plurality of second containers 230 are arranged in a linear array on the carrying platform, and the sorting station 221 has a first outlet 2211 and a second outlet 2212 , and the first The connection line between the first discharge port 2211 and the second discharge port 2212 is in the same direction as the corresponding plurality of second containers 230 arranged in a linear array. The plurality of second containers 230 are arranged in a linear array 230 can reciprocate with the carrying platform under the sorting station 221, so as to adjust the positions of the two second containers 230 to align with the positions of the first outlet 2211 and the second outlet 2212 respectively, that is, The coordinated sorting between the first discharge port 2211, the second discharge port 2212 and the plurality of second containers 230 is realized, which greatly improves the sorting efficiency of goods. It should be noted here that the output end of the reciprocating conveying mechanism is connected to the carrying platform to drive the carrying platform to reciprocate, and the specific connection method is not limited.

In short, the positions of the plurality of second containers 230 are variable, and the second containers 230 can be moved to a position corresponding to the first discharge port 2211 or the second discharge port 2212, and the goods pass through the first discharge port 2211 or the second discharge port 2212. The material port 2211 or the second discharge port 2212 enters the second container 230 under the sorting station 221, wherein the second container 230 under the sorting station 221 is set to be multiple, and by default, a variety of different containers can be used. Sorting of category goods, or sorting of multiple orders.

The working process of the sorting equipment corresponding to the second structural form:

The staff puts the goods on the main feeding line 110 according to the actual operation requirements, and conveys them to the sorting device 200 in an orderly manner through the main feeding line 110; specifically, when the second detection element detects the sorting station corresponding to the No. 1 position When there is no goods on the 221, the main feeding line 110 is controlled by the control device to start, and the goods are delivered to the sorting station 221. When the second detection element detects that there is goods on the sorting station 221 corresponding to the No. 1 position, the control device is passed. The device controls the main feeding line 110 to stop running; when the goods arrive at a sorting station 221, the goods conveyed to the sorting station 221 are discharged through the first outlet 2211 or the second outlet 2212, and fall down into the second container 230 corresponding to the sorting station 221, so as to complete the sorting of the goods; and the sorting mechanism 220 can also move to switch between different sorting stations 221 and the feeding main line 110. Align the ends, and then realize the sorting of different goods.

The specific structure of the sorting device has been described above. Next, the positional relationship between the main feeding line 110 and the main sorting line 210 will be described.

As shown in FIGS. 1 , 2 and 3 , the discharge end of the main feeding line 110 is located above the feeding end of the main sorting line 210 ; and the discharging end of the main feeding line 110 and the feeding end of the main sorting line 210 are There is a predetermined height difference between them.

In some embodiments, referring to FIG. 1 , the height difference H ₁ is less than the height dimension of the cargo on the main sorting line 210 .

In the sorting device of this structure, the value _of the height difference H1 may not be limited, and can be set according to the type of the sorted goods. For example, the value range of the height difference H1 is _0-50mm , Including 0mm, 10mm, 20mm, 30mm, 40mm, 50mm, etc., as long as the height difference is smaller than the height dimension of the goods on the sorting main line 210. Since the value of the height difference H ₁ is not large, it is possible to reduce or even avoid the damage of the goods when they fall due to gravity during the transfer from the main feeding line 110 to the main sorting line 210 .

When the height difference H1 is smaller _than the height dimension of the goods on the main sorting line 210 and the main sorting line 210 is in a closed shape, if the goods on the main sorting line 210 are not sown, they will pass through the entire main sorting line 210 with the The discharge end of the main feeding line 110 touches. In order to alleviate this problem, the main sorting line 210 also includes an end position, which constitutes the entire main sorting line 210 from the feeding end to the end position of the main sorting line 210; wherein, the end position is correspondingly provided with an abnormal container (not shown in the drawings), The abnormal container is used to contain the goods that have not been sown from the infeed end to the end position of the sorting main line 210 . The establishment of the abnormal container can make the unseeded goods enter the fixed receiving mechanism, and prevent the unseeded goods from colliding with the main feeding line 110, thereby affecting the sorting efficiency. For example, the position of the abnormal container can be fixed relative to the ground; multiple abnormal containers can also be set under the end position, and multiple abnormal containers are placed above a container conveyor. The container conveyor has the ability to reciprocate in a straight line and can move many anomalous containers so that one of the anomalous containers is aligned with the discharge opening at the end position. It should be noted that, when the main sorting line 210 is a closed loop, the end position and the feeding end of the main sorting line 210 are arranged adjacent to each other at an interval from the beginning to the end.

Optionally, the outer side of the sorting station 221 corresponding to the end position may also be correspondingly provided with a third detection element (not shown in the drawings, the third detection element may be a photoelectric switch, an image sensor, a gravity sensor, etc.), wherein, The third detection element is controlled by a control device (eg, PLC). The function of the third detection element is to detect whether there is goods on the sorting station 221 corresponding to the end position, and if there is goods, the goods need to be sent into the abnormal container. To put it simply, the goods on the sorting station 221 are driven by the sorting mechanism 220, and the goods that have not been successfully sown can enter the abnormal container during one rotation from the feeding end of the main sorting line 210 to the end position.

Specifically, the sorting mechanism 220 has 20 sorting stations 221 , wherein the first 19 sorting stations 221 correspond to the first container or the second container respectively, and the 20th sorting station 221 corresponds to 1 Among them, the sorting station 221 corresponding to the feeding end position of the sorting main line 210 corresponds to the No. 1 position, the sorting station 221 corresponding to the end position corresponds to the No. 20 position, and the goods enter the sorting station on the No. 1 position. After picking station 221, if the goods are not successfully sown during one rotation of the sorting mechanism 220, when the goods move to the 20th position, once the third detection element detects that there is goods at this position, the information will be sent. To the control device, the control device will control the action of the sorting and conveying assembly after receiving the information, and send the goods into the abnormal container.

In the first structural form of the sorting mechanism 220, if the goods are not sown successfully during one rotation of the sorting mechanism 220, when the sorting mechanism 220 moves to the No. 20 position, the third detection element detects that there is a The goods will send information to the control device, and the control device will control the action of the sorting and conveying components after receiving the information, and send the goods into the abnormal container through the sorting and conveying components, so as to realize the continuous sorting of the goods.

In the second structural form of the sorting mechanism 220, since the position of the second container 230 is variable, in order to ensure that the goods that have not been sown successfully enter the abnormal container smoothly, the position of the sorting main line 210 can be changed. The end position is configured to transfer the goods arriving at the sorting station 221 at this position to the abnormal container through the abnormal goods conveying assembly.

Further, the abnormal goods conveying assembly can be a robot arm, through which the goods that have not been successfully seeded are transferred into the abnormal container; the abnormal goods conveying assembly can also be other forms that can achieve the same function as the above. Specifically, if the goods are not successfully sown during the rotation of the sorting mechanism 220, when the sorting mechanism 220 moves to the No. 20 position, the third detection element detects that there is goods at this position, and sends information to the control device to control the When the device receives the information, it will control the action of the abnormal goods conveying assembly, and send the goods into the abnormal container through the abnormal goods conveying assembly, so as to realize the continuous sorting of the goods.

In other embodiments, referring to FIG. 2 , the height difference H ₂ is greater than the height dimension of the goods on the sorting main line 210 .

It should be noted that the value of the height difference H ₂ is also not limited, and can be set according to the type of the sorted goods. For example, the value range of the height difference H ₂ is 200-500mm, including 200mm, 250mm , 300mm, 350mm, 400mm, 450mm, 500mm, etc., as long as the height difference is greater than the height dimension of the goods on the sorting main line 210. Of course, the value of the height difference H ₂ is not too large, so as to avoid the situation where the goods are damaged when the height difference H ₂ is too large and falls on the main sorting line 210 during the transfer process.

Since the height difference _H2 is greater than the height dimension of the goods on the main sorting line 210, the goods can be smoothly passed through, so that the goods that have not been successfully sown after the sorting mechanism 220 rotates for one turn continue to rotate with the sorting mechanism 220 until the goods are successfully seeded , therefore, there is no need to set the aforementioned exception container.

To sum up the above, the main difference between a sorting device with a height difference of H1 and _a sorting device with a height difference of _H2 is whether an abnormal container needs to be set (specifically, _a sorting device with a height difference of H1 needs to set an abnormal container, Sorting equipment with a height difference of _H2 does not need to set up abnormal containers).

The positional relationship between the main feeding line 110 and the main sorting line 210 has been described above, and the specific structural form of the main feeding line 110 will be introduced next.

There are various structural forms in which the conveying direction of the discharge end of the main feeding line 110 is consistent with the conveying direction of the incoming end of the sorting main line 210 . Exemplarily, the conveying trajectory of the discharge end of the main feeding line 110 is consistent with the conveying trajectory of the incoming end of the main sorting line 210 (see FIG. 3 or FIG. 4 for details); When the conveying trajectory of the feeding end of the main line 210 is the same, the first speed before the goods on the feeding main line 110 are transferred to the sorting main line 210 is exactly the same as the direction of the second speed after the goods are transferred to the sorting main line 210. As far as the main line 110 and the sorting main line 210 are arranged at an angle (that is, the first speed has a sub-speed in the direction perpendicular to the second speed, and the first speed and the second speed can partially cancel each other), the design form of this embodiment The relative speed of the two can be minimized.

Take the L type as an example. The output end of the main feeding line 110 corresponds to a sorting station 221 where the L-shaped sorting mechanism is located at the outermost side of the short side. In a straight line, that is, the goods move along a straight trajectory on the main feeding line 110, and when the goods arrive on the main sorting line 210, they can still be transported along the same straight trajectory as the main feeding line 110, so that the goods can be discharged along the linear trajectory. The end is transferred to the sorting main line 210 .

In addition to the above settings, the conveying trajectory of the discharge end of the main feeding line 110 is inconsistent with the conveying trajectory of the end of the main sorting line 210 where the infeed end is located. The sub-velocity in the direction, this design form can make the relative speed of the above two between the above-mentioned "when the conveying trajectory of the discharge end of the main feeding line 110 is consistent with the trajectory of the end of the main sorting line 210 where the infeed end is located. The relative speed achieved” and “the relative speed achieved by some technologies (the aforementioned main feeding line 110 and the main sorting line 210 are arranged at an angle)”.
