In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Most dysmorphism piece all adopts the carton packing to transport in current commodity circulation transportation, makes article appearance for rectangle or square as far as possible, and the rule is called to the comparison rule in the trade, and the automation of being convenient for is transported and is deposited. However, there are still some types of articles that can be transported in cartons, which results in the inevitable presence of irregularly shaped articles, known in the industry as profiles. Fig. 1 is a schematic view of a logistics flow line provided by an embodiment of the present invention, as shown in fig. 1. The logistics production line is used for transporting the dysmorphism piece, and the dysmorphism piece includes big size dysmorphism piece and small-size dysmorphism piece. The logistics assembly line includes: a transport track, a sorting vehicle 1, a sorting vehicle recognition device, a synchronous detector, a sorting device, a workbench 2, a profile detector 3 and a control system.
The transport track is on a larger scale as a whole and is not shown in fig. 1. The transportation track is the commodity circulation loop in this embodiment, including a starting position, and a plurality of letter sorting car 1 are ended and are linked to each other in proper order, arrange whole transportation track full. A plurality of sorting vehicles 1 are moved cyclically in sequence along the transport track starting from a starting position. The starting position is provided with a sorting vehicle recognition device. One of the sorting vehicles 1 is set as vehicle No. 1, and the vehicle No. 1 is marked with an identification mark. Specifically, in this embodiment, the sorting vehicle identification device is a photoelectric sensor. No. 1 car is gone up and is marked special photoelectric recognition site, and sorting car recognition device can discern this photoelectric recognition site, also can discern No. 1 car promptly. In other embodiments, the identification mark on car No. 1 may also be a bar code, an image or a radio frequency card, and is read by a bar code scanner, a camera or a radio frequency identification device correspondingly.
Fig. 2 is a schematic view of a sorting vehicle according to an embodiment of the present invention, and as shown in fig. 2, the sorting vehicle 1 includes a tray 11, and the tray 11 is used for carrying a profile. Each tray 11 is provided with at least one row of light transmissive regions, and each row of light transmissive regions includes at least one light transmissive hole 111. The edge of tray 11 is equipped with the connection buckle, can be through connecting buckle interconnect between the many letter sorting car 1. The spacing between two adjacent sorting vehicles 1 is the same, and this spacing is called the pitch. In particular, in the present embodiment, the pitch is the car length of the sorting car 1, i.e. a plurality of sorting cars 1 are arranged next to one another. In addition, the bottom of letter sorting car 1 is equipped with the roller train, and the roller train makes letter sorting car 1 can follow the transportation track quick travel.
It should be noted in detail that the plurality of sorting vehicles 1 moving in sequence along the transportation track means that the plurality of sorting vehicles 1 do not have the situation that two or more sorting vehicles 1 move in parallel along the transportation track, so as to prevent the sorting vehicles 1 from disordering in sequence or abnormal articles from being placed in the tray 11 of the sorting vehicle 1 in time due to the parallel running, and the missing of the articles is caused.
And a synchronous detector is also arranged on the transportation track and used for counting. The synchronous detector refreshes and counts again each time the car number 1 passes the initial position. The control system is able to calculate the position of each sorting vehicle 1 from the count of the synchronous detectors.
In particular, a common way of counting is exemplarily indicated. First, each sorting vehicle 1 is provided with a plurality of holes on its side edge, and the distance between two adjacent holes is the same, for example, the distance between two adjacent holes is one tenth of the pitch. When the sorting carts 1 are moved forward in a sequential cycle, the synchronization detector is triggered once every time a hole on the side of a sorting cart 1 passes the synchronization detector, the count is increased by 1, which corresponds to a tenth pitch of the forward movement of the whole of the sorting carts 1. The control system can calculate the distance of the No. 1 vehicle from the initial position, namely the position of the No. 1 vehicle according to the counting of the synchronous detector and the corresponding hole distance. Since the pitch between the individual sorting carts 1 is the same, the position of the individual sorting carts 1 can be calculated in turn.
The sorting device can sort the special-shaped pieces into small-size special-shaped pieces and large-size special-shaped pieces, and convey the small-size special-shaped pieces and the large-size special-shaped pieces which are distinguished to the workbench 2 respectively. In this embodiment, two conveyor belts are provided between the sorting device and the table 2 for conveying the sorted small-size profile pieces and large-size profile pieces, respectively.
The work table 2 includes an automatic part feeder 21 and a first recognition device, the automatic part feeder 21 includes a conveyor configured to be able to convey a small-sized irregularly-shaped part onto the tray 11; fig. 3 is a cross-sectional view of a conveyor according to an embodiment of the present invention, as shown in fig. 3. The automatic part feeder 21 includes a conveyor. It should be noted that, after the installation of the work table 2 is completed, the distance between each automatic workpiece feeder 21 and the initial position of the transportation rail is known. After the control system calculates the position of the No. 1 vehicle and the positions of the sorting vehicles 1 through the counting of the synchronous detectors, the distance between each automatic workpiece feeder 21 and the initial position can be combined to calculate which automatic workpiece feeder 21 the No. 1 vehicle passes through, so that small-size special-shaped parts conveyed by the automatic workpiece feeder 21 are correspondingly bound with the vehicle number of the passing sorting vehicle 1.
Specifically, in the present embodiment, the conveyor is a conveying belt, one end of which is a loading end and is located near the workbench 2; the other end of the conveyor belt is an unloading end. The conveyor belt can transport small-sized profiled elements onto the trays 11 of the sorting car 1 when the sorting car 1 passes the unloading end. As a preferred technical scheme, push heads are arranged on the conveying belt at intervals, the conveying belt is divided into a plurality of conveying positions by the push heads, and each conveying position is provided with a small-size special-shaped piece, so that the small-size special-shaped pieces on the conveying belt are conveyed in sequence, and missing conveying and stacking are prevented.
In other embodiments, the automatic part feeder 21 is not provided when all the profile members have a size greater than or equal to the article size threshold.
The first identification means are used for reading the article information of the profile. Specifically, in this embodiment, the first identification device is a barcode scanner, which correspondingly identifies barcode information on the special-shaped piece so as to obtain article information of the special-shaped piece. Because article information of dysmorphism piece is difficult to be read by the machine, the error rate is high, so adopt artifical use bar code ware to read article information of dysmorphism piece, improve the discernment rate of accuracy. In some other embodiments, the first identification device can be replaced by a radio frequency identification device, which correspondingly identifies a radio frequency card on the profile piece to obtain the article information of the profile piece. The article information of the profile includes but is not limited to: order information, physical distribution path information, article type information, and the like.
A plurality of profile detectors 3 are arranged at intervals on the transport track starting from the starting position. A sorting device and a workbench 2 are arranged between every two adjacent detectors 3. The shaped-piece detector 3 is configured to recognize whether or not there is a shaped piece on the tray 11. It should be noted that, when the installation of the profile detectors 3 is completed, the distance between each profile detector 3 and the initial position of the transport track is known. Preferably, the spacing between each two adjacent profile detectors 3 is the same. After the control system calculates the position of the No. 1 vehicle and the positions of the sorting vehicles 1 through the counting of the synchronous detectors, the control system can calculate which special-shaped piece detector 3 the No. 1 vehicle passes through by combining the distance between each special-shaped piece detector 3 and the initial position, so that the detection result of the special-shaped piece detector 3 and the vehicle number of the passing sorting vehicle 1 are correspondingly recorded.
In the present embodiment, the profile detector 3 includes a light beam emitter and a light beam receiver, and the light beam emitter and the light beam receiver constitute a correlation type photoelectric sensor. The light beam transmitter is positioned on one side of the transportation track right above or right below, and the light beam receiver is positioned on the other side of the transportation track right above or right below. The light beam emitted by the light beam emitter is configured to pass through the light-transmissive aperture 111 and be received by the light beam receiver. When the sorting car 1 passes through the special-shaped piece detector 3, the light beam receiver can receive all light beams emitted by the light beam emitter, and then the sorting car 1 is judged to be unloaded; the light beam receiver can not receive all the light beams emitted by the light beam emitter, and then the sorting vehicle 1 is judged not to be unloaded. In other embodiments, it is easy to conceive of changing the arrangement orientation of the light beam emitter and the light beam receiver, never forming a refractive photoelectric sensor, which belongs to the conventional arrangement of the invention in the specific application scenario.
Continuing to refer to fig. 2, for example, in the present embodiment, four rows of light-transmitting regions are provided on the tray 11, each row of light-transmitting region includes two light-transmitting holes 111, each light-transmitting hole 111 includes four sub light-transmitting holes arranged at intervals and equal in size, and the sub light-transmitting holes are through holes. In other embodiments, the sub-light-transmitting holes may be arranged in a manner that the through holes are filled with transparent materials. If the tray 11 carries a profile, the profile can cover part or all of the light-transmitting holes 111. When the sorting car 1 passes through the special-shaped piece detector 3, the light beam receiver can receive all light beams emitted by the light beam emitter, namely all identical and complete rectangular light beams, and then the sorting car 1 is judged to be in no-load; when the light beam receiver can not receive the identical and complete rectangular light beam, the sorting vehicle 1 is judged to be loaded with the special-shaped piece.
Further, in the embodiment thereof, the light beam emitter and the light beam receiver may be replaced with a distance sensor, and the distance sensor is disposed directly above the transport rail 1. When the sorting car 1 passes through the special-shaped piece detector 3, the distance sensor sends an infrared signal or a sound wave signal, the signal is reflected by the sorting car 1 or the special-shaped piece and then received by the distance sensor, and the distance between the distance sensor and the sorting car 1 or the special-shaped piece is obtained through calculation. Setting the distance value of the sorting vehicle 1 in the no-load state as a distance threshold value, and judging that the sorting vehicle 1 carries a special-shaped piece when the detected distance value is smaller than the distance threshold value; and when the detected distance value is equal to the distance threshold value, judging that the sorting vehicle 1 is in an idle state.

as a preferable embodiment, the article size threshold may be set according to the interval of the light-transmitting holes 111, or may be set according to the size of the tray 11 or the size of the conveyor. The principle of the arrangement is to ensure that a profile having a maximum outer dimension greater than the threshold value of the article size can cover part or all of the light-transmitting holes 111 after being placed in the tray 11, and that a profile having a maximum outer dimension less than the threshold value of the article size can be conveyed onto the tray 11 using the conveyor.
