Description

Technical Field

[0001] The present invention relates to the field of automatic sorting technology, and in particular to a logistics assembly line and a method for binding article information with a sorting vehicle. Background Art

[0002] In today's life, with the booming development of the e-commerce industry, the logistics industry has also achieved synchronous and rapid development. In the existing logistics transportation, most special-shaped parts are transported in cartons, so that the shape of the items is as rectangular or square as possible, which is relatively regular. They are called regular parts in the industry, which are convenient for automatic transportation and storage. However, there are still some special-shaped parts with irregular shapes, which are called special-shaped parts in the industry. Sorting of special-shaped parts is a major problem in automatic sorting of items. The main reason is that the irregular shape causes the posture of the items to be unstable, the barcode is not easy to read, and it is easy to roll and slip, which is not conducive to transportation and sorting.

[0003] There are few devices in the prior art that can realize automatic sorting of special-shaped parts. Basically, grayscale detection and binding are adopted. The detection and binding accuracy is low and cannot meet the use requirements. It is also prone to false detection, high cost, and large equipment site occupation. In addition, the disc sorting machine can sort special-shaped parts, but because the barcode information of special-shaped parts is not easy to automatically identify, manual assisted sorting is generally adopted. The specific working method is to manually read the barcode information and the sorting vehicle number of the item, and after two steps of manual information reading, the item is placed on the corresponding sorting vehicle to bind the item information with the sorting vehicle number. The degree of automation is low. Summary of the invention

[0044] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0045] In the existing logistics transportation, most of the special-shaped items are transported in cartons, so that the shape of the items is as rectangular or square as possible, which is relatively regular. In the industry, it is called regular items, which is convenient for automated transportation and storage. However, there are still some categories of items that can be transported in cartons, which inevitably leads to the existence of special-shaped items with irregular shapes, which are called special-shaped items in the industry. Figure 1 It is a schematic diagram of a logistics flow line provided by a specific embodiment of the present invention, such as Figure 1 As shown. The logistics assembly line is used to transport special-shaped parts, including large-sized special-shaped parts and small-sized special-shaped parts. The logistics assembly line includes: a transport track, a sorting vehicle 1, a sorting vehicle identification device, a synchronous detector, a sorting device, a workbench 2, a special-shaped part detector 3 and a control system.

[0046] The overall scale of the transport track is large. Figure 1 Not shown. In the present embodiment, the transport track is a logistics loop, including a starting position, and a plurality of sorting vehicles 1 are connected in sequence at the end to fill the entire transport track. A plurality of sorting vehicles 1 move in a circular sequence along the transport track starting from the starting position. A sorting vehicle identification device is provided at the starting position. One of the sorting vehicles 1 is set as vehicle No. 1, and vehicle No. 1 is marked with an identification mark. Specifically, in the present embodiment, the sorting vehicle identification device is a photoelectric sensor. A special photoelectric identification site is marked on vehicle No. 1, and the sorting vehicle identification device can identify the photoelectric identification site, that is, it can identify vehicle No. 1. In other embodiments, the identification mark on vehicle No. 1 may also be a barcode, an image or a radio frequency card, and is read accordingly by a barcode scanner, a camera or a radio frequency identification device.

[0047] Figure 2 Schematic diagram of a sorting vehicle provided in a specific embodiment of the present invention, such as Figure 2 As shown, the sorting cart 1 includes a tray 11, and the tray 11 is used to carry special-shaped parts. Each tray 11 is provided with at least one column (row) of light-transmitting areas, and each column (row) of light-transmitting areas includes at least one light-transmitting hole 111. Connecting buckles are provided on the edge of the tray 11, and multiple sorting carts 1 can be connected to each other through the connecting buckles. The distance between each two adjacent sorting carts 1 is the same, and this distance is called the pitch. Specifically, in this embodiment, the pitch is the length of the sorting cart 1, that is, multiple sorting carts 1 are arranged closely in sequence. In addition, a roller group is provided at the bottom of the sorting cart 1, and the roller group enables the sorting cart 1 to move quickly along the transport track.

[0048] It should be explained in detail that the multiple sorting vehicles 1 move in sequence along the transport track, which means that there are no two or more sorting vehicles 1 moving side by side along the transport track, so as to prevent the order of the sorting vehicles 1 from being disordered due to side by side driving or the special-shaped parts from being unable to be placed in the tray 11 of the sorting vehicle 1 in time, resulting in omissions.

[0049] A synchronous detector is also provided on the transport track, and the synchronous detector is used for counting. Whenever the No. 1 vehicle passes the initial position, the synchronous detector is refreshed and counted again. The control system can calculate the position of each sorting vehicle 1 according to the count of the synchronous detector.

[0050] Specifically, a common counting method is pointed out as an example. The first one is that a plurality of holes are provided on the side of each sorting vehicle 1, and the distance between each two adjacent holes is the same, for example, the distance between each two adjacent holes is one tenth of the pitch. When the sorting vehicle 1 circulates forward in sequence, each time a hole on the side of the sorting vehicle 1 passes through the synchronous detector, the synchronous detector is triggered once, and the count is increased by 1, which is equivalent to the overall movement of multiple sorting vehicles 1 forward by one tenth of the pitch. Therefore, the control system can calculate the distance of vehicle No. 1 from the initial position, that is, the position of vehicle No. 1, based on the count of the synchronous detector and the corresponding hole spacing. And because the pitch between each sorting vehicle 1 is the same, the position of each sorting vehicle 1 can be calculated in sequence.

[0051] The sorting device can sort the special-shaped parts into small-sized special-shaped parts and large-sized special-shaped parts, and transport the small-sized special-shaped parts and large-sized special-shaped parts to the workbench 2. In this embodiment, two conveyor belts are provided between the sorting device and the workbench 2, which are used to transport the small-sized special-shaped parts and large-sized special-shaped parts after the sorting.

[0052] The workbench 2 includes an automatic loading machine 21 and a first identification device. The automatic loading machine 21 includes a conveyor, and the conveyor is configured to convey small-sized special-shaped parts to the tray 11; Figure 3 is a cross-sectional view of a conveyor provided in a specific embodiment of the present invention, such as Figure 3 As shown. The automatic loading machine 21 includes a conveyor. It should be noted that after the workbench 2 is installed, the distance between each automatic loading machine 21 and the initial position of the transport track is known. After the control system calculates the position of vehicle No. 1 and the positions of each sorting vehicle 1 through the counting of the synchronous detector, it can then calculate which vehicle No. is passing through which automatic loading machine 21 in combination with the distance between each automatic loading machine 21 and the initial position, thereby correspondingly binding the small-sized special-shaped parts transported by the automatic loading machine 21 and the vehicle number of the sorting vehicle 1 passing by.

[0053] Specifically, in this embodiment, the conveyor is a conveyor belt, one end of which is the loading end, located near the workbench 2; the other end of the conveyor belt is the unloading end. When the sorting vehicle 1 passes the unloading end, the conveyor belt can convey the small-sized special-shaped parts to the tray 11 of the sorting vehicle 1. As a preferred technical solution, pushers are arranged at intervals on the conveyor belt, and the plurality of pushers separate the conveyor belt into a plurality of conveying positions, each of which is placed with a small-sized special-shaped part, so that the small-sized special-shaped parts on the conveyor belt are conveyed in order to prevent missing and accumulation.

[0054] In other embodiments, when the sizes of all the special-shaped parts are greater than or equal to the object size threshold, the automatic loading machine 21 is not provided.

[0055] The first identification device is used to read the item information of the irregular-shaped part. Specifically, in the present embodiment, the first identification device is a barcode scanner, which corresponds to identifying the barcode information on the irregular-shaped part to obtain the item information of the irregular-shaped part. Because the item information of the irregular-shaped part is not easy to be read by a machine and the error rate is high, the item information of the irregular-shaped part is read manually using a barcode scanner to improve the recognition accuracy. In some other embodiments, the first identification device can be replaced by a radio frequency identification device, which corresponds to identifying the radio frequency card on the irregular-shaped part to obtain the item information of the irregular-shaped part. The item information of the irregular-shaped part includes, but is not limited to: order information, logistics path information, and item type information.

[0056] A plurality of special-shaped part detectors 3 are arranged at intervals from the starting position on the transport track. A sorting device and a workbench 2 are provided between each two adjacent detectors 3. The special-shaped part detector 3 is configured to be able to identify whether there are special-shaped parts on the tray 11. It should be noted that after the special-shaped part detector 3 is installed, the distance between each special-shaped part detector 3 and the initial position of the transport track is known. Preferably, the spacing between each two adjacent special-shaped part detectors 3 is the same. After the control system calculates the position of vehicle No. 1 and the positions of its various sorting vehicles 1 by counting the synchronous detector, it can calculate which vehicle No. is passing through which special-shaped part detector 3 in combination with the distance between each special-shaped part detector 3 and the initial position, thereby recording the detection result of the special-shaped part detector 3 and the vehicle number of the sorting vehicle 1 passing by.

[0057] In this embodiment, the special-shaped part detector 3 includes a light beam emitter and a light beam receiver, and the light beam emitter and the light beam receiver constitute a beam-type photoelectric sensor. The light beam emitter is located on one side directly above or directly below the transport track, and the light beam receiver is located on the other side directly above or directly below the transport track. The light beam emitted by the light beam emitter is configured to pass through the light-transmitting hole 111 and be received by the light beam receiver. When the sorting vehicle 1 passes through the special-shaped part detector 3, if the light beam receiver can receive all the light beams emitted by the light beam emitter, it is judged that the sorting vehicle 1 is unloaded; if the light beam receiver cannot receive all the light beams emitted by the light beam emitter, it is judged that the sorting vehicle 1 is not unloaded. In other embodiments, it is easy to think of changing the arrangement orientation of the light beam emitter and the light beam receiver, and never forming a refractive photoelectric sensor. This scheme belongs to the conventional setting of the present invention in a specific application scenario.

[0058] Continue to refer to Figure 2, it is pointed out exemplarily that in the present embodiment, four columns of light-transmitting areas are provided on the tray 11, each column of light-transmitting areas includes two light-transmitting holes 111, each light-transmitting hole 111 includes four sub-light-transmitting holes that are arranged at intervals and are equal in size, and all of the sub-light-transmitting holes are through holes. In other embodiments, the sub-light-transmitting holes may also be arranged in a manner in which the through holes are filled with transparent materials. If the tray 11 carries special-shaped parts, the special-shaped parts can cover part or all of the light-transmitting holes 111. When the sorting vehicle 1 passes through the special-shaped part detector 3, the light beam receiver can receive all the light beams emitted by the light beam transmitter, that is, a completely identical and complete rectangular light beam, then the sorting vehicle 1 is judged to be empty; when the light beam receiver cannot receive a completely identical and complete rectangular light beam, then it is judged that the sorting vehicle 1 is carrying special-shaped parts.

[0059] Furthermore, in the embodiment, the light beam transmitter and the light beam receiver can be replaced by a distance sensor, and the distance sensor is arranged directly above the transport track 1. When the sorting vehicle 1 passes the special-shaped part detector 3, the distance sensor sends an infrared signal or a sound wave signal, which is reflected by the sorting vehicle 1 or the special-shaped part and then received by the distance sensor, and the distance between the distance sensor and the sorting vehicle 1 or the special-shaped part is obtained by calculation. The distance value of the empty state of the sorting vehicle 1 is set as the distance threshold. When the detected distance value is less than the distance threshold, it is judged that the sorting vehicle 1 is loaded with special-shaped parts; when the detected distance value is equal to the distance threshold, it is judged that the sorting vehicle 1 is empty.

[0060] Based on the logistics flow line of any one of the above technical solutions, the present invention also discloses a method for binding item information with a sorting vehicle, comprising the following steps:

[0061] S10, setting an item size threshold; the sorting device distinguishes the special-shaped parts according to the size. When the maximum external dimension of the special-shaped part is less than the item size threshold, it is marked as a small-sized special-shaped part; when the maximum external dimension of the special-shaped part is greater than or equal to the item size threshold, it is marked as a large-sized special-shaped part;

[0062] As a preferred technical solution, the object size threshold can be set according to the interval of the light-transmitting holes 111, or according to the size of the tray 11 or the size of the conveyor. The setting principle is to ensure that the special-shaped parts with the maximum external dimensions greater than the object size threshold can cover part or all of the light-transmitting holes 111 after being placed in the tray 11, and the special-shaped parts with the maximum external dimensions less than the object size threshold can be transported to the tray 11 using the conveyor.

[0063] The sorting device separates the irregular parts by size, including the following steps:

[0064] S11, placing the special-shaped parts into the scale position of the sorting device, where the scale position includes a three-dimensional spatial coordinate ruler;

[0065] S12, the image recognition system in the sorting device obtains the front view, top view and left view of the special-shaped part, reads the dimensions of the special-shaped part in the length, width and height directions from the image, and records the dimension data of each special-shaped part;

[0066] S13, constructing a virtual space cuboid according to the dimensions of the length, width and height of the special-shaped part;

[0067] S14, taking the diagonal length of the virtual space cuboid as the maximum external dimension of the special-shaped part;

[0068] S15. Compare the maximum external dimension with the object dimension threshold.

[0069] As a preferred technical solution, the sorting device includes a three-dimensional scanner, and the sorting device distinguishes the special-shaped parts according to size, including the following steps:

[0070] S11, placing the special-shaped parts into the scanning area of ​​the sorting device, and obtaining the three-dimensional size data of the special-shaped parts by a three-dimensional scanner;

[0071] S12, filtering out the maximum dimensions of the length, width and height directions of the special-shaped parts from the three-dimensional dimension data of the special-shaped parts, and recording the dimension data of each special-shaped part;

[0072] S13, reconstructing a cuboid in a virtual space based on the maximum dimensions of the length, width and height of the special-shaped part;

[0073] S14, taking the diagonal length of the cuboid as the maximum outer dimension of the special-shaped part;

[0074] S15. Compare the maximum external dimension with the object dimension threshold.

[0075] S20, manually using the first recognition device to sequentially read the item information of the small-sized special-shaped parts;

[0076] The special-shaped part detector 3 identifies whether there are special-shaped parts on the tray 11; the sorting vehicle 1 without special-shaped parts on the tray 11 is marked as an empty sorting vehicle in the control system;

[0077] S30, when the empty sorting vehicle passes the workbench 2, the automatic loading machine 21 sequentially conveys the small-sized and special-shaped parts to the tray 11 of the empty sorting vehicle;

[0078] S40, binding the item information of the small-sized and special-shaped parts with the vehicle number of the empty sorting vehicle in order, and canceling the mark of the empty sorting vehicle in the control system;

[0079] The order of the small-sized and irregular parts is the order read by the first identification device, and the vehicle number of the empty sorting vehicle is calculated by the control system according to the count of the synchronous detector and the position of the automatic loading machine 21. The specific process is: after the control system calculates the position of the No. 1 vehicle and the positions of each of its sorting vehicles 1 through the count of the synchronous detector, it calculates which vehicle is passing through which automatic loading machine 21 in combination with the distance between each automatic loading machine 21 and the initial position, thereby correspondingly binding the small-sized and irregular parts transported by the automatic loading machine 21 and the vehicle number of the sorting vehicle 1 of the automatic loading machine 21 that is passing through.

[0080] S50, manually using the first recognition device to sequentially read the item information of the large-sized special-shaped parts; and sequentially conveying the large-sized special-shaped parts to the tray 11 of the empty sorting vehicle;

[0081] S60, when the empty sorting vehicle passes the next special-shaped component detector 3, the special-shaped component detector 3 identifies whether there is a special-shaped component on the tray 11 of the empty sorting vehicle;

[0082] If there are irregular-shaped parts on the tray 11 of the empty sorting vehicle, the item information of the large-sized irregular-shaped parts and the vehicle number of the empty sorting vehicle are bound in order, and the mark of the empty sorting vehicle is cancelled in the control system;

[0083] If there are no special-shaped parts on the tray 11 of the empty sorting vehicle, the empty sorting vehicle will continue to be marked as an empty sorting vehicle in the control system.

[0084] The order of the large-sized and irregular parts is the order read by the first identification device, and the vehicle number of the empty sorting vehicle is calculated by the control system according to the count of the synchronous detector and the position of the irregular part detector 3. The specific process is: after the control system calculates the position of the No. 1 vehicle and the positions of each sorting vehicle 1 through the count of the synchronous detector, it can calculate which vehicle is passing which irregular part detector 3 in combination with the distance between each irregular part detector 3 and the initial position, so as to record the detection result of the irregular part detector 3 and the vehicle number of the sorting vehicle 1 passing the irregular part detector 3 in correspondence.

[0085] As a preferred technical solution, after binding the item information of the special-shaped parts with the vehicle number of the empty sorting vehicle, the following steps are also included: the item information of the special-shaped parts includes an address grid, and when the empty sorting vehicle arrives at the corresponding address grid, the special-shaped parts are unloaded to the address grid.
