Description

Technical Field

[0001] The invention relates to a clothing hanging system, in particular to a clothing hanging multi-channel entry control method. Background Art

[0002] The clothing hanging system is used to realize the preparation of clothing from cut pieces to finished garments. The structure includes a circular main rail, and a number of workstations are arranged along the main rail. Workstations are formed at the positions of these workstations, and sewing machine tables are placed at the workstations. Operators sit at the sewing machine tables to sew the fabrics. The structure of the existing workstation includes an integrated entry rail and an exit rail, both of which are connected to the main rail. A waiting position is formed at the connection position between the entry rail and the exit rail. The carrier holding the fabric changes from the main rail to the entry rail and ends at the waiting position. After the operator completes the corresponding process, the carrier is lifted from the exit branch rail to the main rail under the push of the lifting device for sewing the next process.

[0003] In the context of the current clothing production industry's trend towards a small-order, quick-response model, it is common to frequently switch between different clothing styles for production. When a clothing production line is in production and an urgent order needs to be arranged to prioritize the production of a new style of clothing, the current production process must be switched. The clothing hanging production line, due to its digital and intelligent advantages, can flexibly switch production processes, which is more efficient and convenient than traditional production models. One of the points is to use a multi-channel entry and multi-track caching method to arrange multiple different production processes in parallel in a hanging workstation.

[0004] For example, the Chinese patent with the published announcement number CN209427637U and the name "Overload Station of Garment Hanging System" discloses an overload station of garment hanging system, which has an entrance side and an exit side. An entrance branch rail is arranged at the entrance side, and an entrance swing head for receiving hangers on the main rail is arranged at the entrance end of the entrance branch rail, and a limiting device for limiting the movement of hangers is arranged at the exit end of the entrance branch rail; an exit branch rail is arranged at the exit side, and the exit end of the exit branch rail extends toward the main rail, and is characterized in that there are multiple entrance branch rails, and the exit end of the entrance branch rail and the entrance end of the exit branch rail extend toward each other, and a track changing mechanism is arranged at the exit end of the entrance branch rail and the entrance end of the exit branch rail to realize the communication between different exit ends of the entrance branch rails and the inlet end of the exit branch rail.

[0005] In the prior art, a station entry card reader is often provided at each branch rail entrance, which has a complex structure and high cost. Meanwhile, when more branch rails are provided, the branch rail entrance space is small and cannot be used for the station entry card reader. Summary of the invention

[0006] The present application provides a method for controlling multi-channel entry of clothing hanging, which solves the technical problems in the prior art that the multi-channel entry workstation has a complex structure and high cost, and at the same time, there is no space to install an entry card reader when the number of branch rails is large. The present application realizes that the entire multi-channel entry workstation only needs one entry card reader and is combined with a software algorithm for intelligent control to achieve simplified structure, reduced cost and efficient entry and exit control.

[0007] A clothing hanging multi-channel entry control method, characterized in that a station entry card reader installed on a main rail is provided, comprising the following steps:

[0008] S1. When the station entry card reader detects that a vehicle passes through the station entry card reader on the main track, the station entry card reader reads the vehicle information on the vehicle and sends the vehicle information to the station controller;

[0009] S2, the station controller determines which branch rail the vehicle is going to enter according to the received vehicle information, defines the branch rail the vehicle is going to enter as the target branch rail to be entered, and at the same time the station controller starts timing T1;

[0010] S3, when the above T1 reaches the preset opening time T of the branch rail entry valve on the target branch rail to be entered, the station controller detects the station entry full photoelectric signal on the target branch rail to be entered and controls the branch rail entry valve to not open so that the vehicle cannot enter the station or to open it to allow the vehicle to enter the station according to the presence or absence of the station entry full photoelectric signal;

[0011] Among them, the station-full photoelectric signal is used to detect whether the number of vehicles on the corresponding branch rail has reached the upper limit.

[0012] This solution only requires one entry card reader, and there is no need to set up an entry card reader at the front end of each branch rail. The timing for the vehicle to enter the corresponding branch rail is calculated and controlled by software algorithms, which simplifies the structure, reduces costs, and makes the control more flexible through the control method of software algorithms.

[0013] In the above-mentioned clothing hanging multi-channel entry control method, it is characterized in that the preset opening time T of the branch rail entry valve in step S3 is obtained by dividing the distance between the entry card reader and the target branch rail to be entered by the running speed of the main rail, and is preset and stored in the station controller.

[0014] The distance between different branch rails and the station entry card reader is a fixed distance value after installation. These different distance values ​​are preset in the station controller. The main rail running speed can be directly sent to the station controller by the main rail control system. Based on these two data, the preset opening time T of the corresponding branch rail entry valve can be calculated.

[0015] In the above-mentioned clothing hanging multi-channel entry control method, it is characterized in that the preset opening time T of the branch rail entry valve in step S3 is less than the actual time value obtained by dividing the distance between the entry card reader and the target branch rail to be entered by the running speed of the main rail.

[0016] Since the running speed of the main rail may change in actual work, for example, the actual running speed of the main rail becomes faster, then after the preset opening time T, the actual vehicle has passed the branch rail to be entered. At this time, opening the branch rail entry valve will not allow the vehicle to enter the branch rail. Therefore, in order to ensure that this problem is avoided, the preset opening time T of the branch rail entry valve is set to a smaller size to ensure that the vehicle is in front of or just at the corresponding branch rail after the preset opening time T.

[0017] In the above-mentioned clothing hanging multi-channel entry control method, it is characterized in that the carrier information in step S1 includes the carrier number, the specific fabric carried on the carrier, and the station information of which workstation to enter and which branch rail in which workstation to enter for processing.

[0018] In the above-mentioned clothing hanging multi-channel entry control method, it is characterized in that the entry card reader is installed on the main rail located at the front end of the multi-channel workstation, or is installed at a position on the main rail away from the multi-channel workstation.

[0019] The station entry card reader is preferably installed on the front end which is closer to the multi-channel workstation, so that the actual timing T1 is closer to the preset opening time T of the branch rail station entry valve, and the time node for controlling the opening of the branch rail station entry valve is more accurate and the control is precise; when there is no suitable installation position near the front end of the multi-channel workstation, such as there is no space for installation due to a small space, then you can choose to install it at other positions on the main rail far away from the multi-channel workstation, thereby overcoming the defect that the station entry card reader cannot be installed at the front end of the multi-channel workstation due to the small space. As for the problem of low accuracy that may be caused by the long distance, it can be corrected by an algorithm, or the branch rail station entry valve can be opened when the actual timing T1 reaches a certain degree of the preset opening time T of the branch rail station entry valve, such as when the actual timing T1 reaches 95% of the preset opening time T of the branch rail station entry valve, to ensure that the branch rail station entry valve is opened before the vehicle reaches the corresponding branch rail, to avoid the vehicle having passed the branch rail position and then opening the branch rail station valve and thus missing the opportunity to enter the track.

[0020] In the above-mentioned clothing hanging multi-channel entry control method, it is characterized in that the station controller starts timing T1 in step S2 by timing through a timer in the station controller, or is calculated by software.

[0021] In the above-mentioned clothing hanging multi-channel entry control method, it is characterized in that the number of the branch rails is two or more.

[0022] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0023] Since a single entry card reader combined with a software algorithm is used for precise control, only one entry card reader is required and the installation position requirement for the entry card reader is low. Therefore, the defect that an entry card reader must be installed on each branch rail, resulting in a complex structure and high cost, especially when there is no space at the front end of the branch rail, the entry card reader cannot be installed, is effectively solved. The beneficial effects of simplifying the structure, reducing costs and having low requirements for the installation position of the entry card reader so that there will be no situation where there is no space and it cannot be installed, are achieved.

[0028] The embodiment of the present application solves the technical problems in the prior art that the multi-channel station entry workstation has a complex structure and high cost, and there is no space to install the station entry reader when there are many branch rails, by providing a station entry card reader combined with a software algorithm for intelligent control.

[0029] The technical solution in the embodiment of the present application is to solve the above-mentioned crosstalk problem, and the overall idea is as follows:

[0030] By providing a station entry card reader installed on the main rail, and combining software algorithms to implement intelligent control methods, such as Figure 1 As shown, the control method mainly includes the following steps:

[0031] S1. When the station entry card reader detects that a vehicle passes through the station entry card reader on the main track, the station entry card reader reads the vehicle information on the vehicle and sends the vehicle information to the station controller;

[0032] S2, the station controller determines which branch rail the vehicle is going to enter according to the received vehicle information, defines the branch rail the vehicle is going to enter as the target branch rail to be entered, and at the same time the station controller starts timing T1;

[0033] S3, when the above T1 reaches the preset opening time T of the branch rail entry valve on the target branch rail to be entered, the station controller detects the station entry full photoelectric signal on the target branch rail to be entered and controls the branch rail entry valve to not open so that the vehicle cannot enter the station or to open it to allow the vehicle to enter the station according to the presence or absence of the station entry full photoelectric signal;

[0034] Among them, the station-full photoelectric signal is used to detect whether the number of vehicles on the corresponding branch rail has reached the upper limit.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Embodiment 1

[0037] This embodiment 1 provides a method for controlling the multi-channel entry of clothing hanging, including providing an entry card reader installed on the main rail, such as Figure 1 As shown, the following steps are also included:

[0038] S1. When the station entry card reader detects that a vehicle passes through the station entry card reader on the main track, the station entry card reader reads the vehicle information on the vehicle and sends the vehicle information to the station controller;

[0039] The vehicle information specifically includes the vehicle number, the specific fabric carried on the vehicle, which workstation to enter, and which branch track in which workstation to enter for processing, etc. Of course, other information may also be included as needed;

[0040] S2, the station controller determines which branch rail the vehicle is going to enter according to the received vehicle information, defines the branch rail the vehicle is going to enter as the target branch rail to be entered, and at the same time the station controller starts timing T1;

[0041] Among them, the station controller starts timing T1 through the timer in the station controller, and of course it can also be calculated by software, which can be achieved by existing technology;

[0042] S3, when the above T1 reaches the preset opening time T of the branch rail entry valve on the target branch rail to be entered, the station controller detects the station entry full photoelectric signal on the target branch rail to be entered and controls the branch rail entry valve to not open so that the vehicle cannot enter the station or to open it to allow the vehicle to enter the station according to the presence or absence of the station entry full photoelectric signal;

[0043] Among them, the photoelectric signal of full station entry is used to detect whether the number of vehicles on the corresponding branch rail has reached the upper limit; when the photoelectric signal of full station entry is detected, it means that the vehicles on the corresponding branch rail are already fully loaded and no more vehicles can be allowed to enter the branch rail. At this time, the station controller controls the branch rail entry valve to be closed and not opened. In this case, the vehicle does not enter the station and continues to run on the main rail. It will wait until the next cycle returns to this point to determine whether to enter the station; when the photoelectric signal of full station entry is not detected, it means that the vehicles on the corresponding branch rail are not fully loaded, and the station controller controls the branch rail entry valve to open to allow the vehicle to enter the branch rail.

[0044] The entry card reader of this embodiment is installed on the main rail located at the front end of the multi-channel workstation, that is, close to the front of the multi-channel workstation; if the position near the multi-channel workstation is relatively narrow and there is no space for installation, it can also be installed at a position on the main rail away from the multi-channel workstation, so the requirements for its installation position are relatively low. Specifically, the entry card reader is preferentially installed on the front end portion which is closer to the multi-channel workstation, so that the actual timing T1 is closer to the preset opening time T of the branch rail entry valve, and the time node for controlling the opening of the branch rail entry valve is more accurate and the control is precise; when there is no suitable installation position near the front end of the multi-channel workstation, for example, there is no space for installing the multi-channel workstation due to a small space, then you can choose to install it at other positions of the branch rail far away from the multi-channel workstation, thereby overcoming the defect that the entry card reader cannot be installed at the front end of the multi-channel workstation due to the small space. As for the problem of low accuracy that may be caused by the long distance, it can be corrected through an algorithm, or the branch rail entry valve can be opened when the actual timing T1 reaches a certain degree of the preset opening time T of the branch rail entry valve, for example, the branch rail entry valve can be opened when the actual timing T1 reaches 95% of the preset opening time T of the branch rail entry valve, to ensure that the branch rail entry valve is opened before the vehicle reaches the corresponding branch rail, to avoid the vehicle having passed the branch rail position and then opening the branch rail entry valve, thereby missing the opportunity to enter the track.

[0045] The preset opening time T of the branch rail entry valve is obtained by dividing the distance between the entry card reader and the target branch rail to be entered by the main rail running speed, and is preset and stored in the station controller. The distance between different branch rails and the entry card reader is a certain distance value after installation. These different distance values ​​are preset in the station controller, and the main rail running speed can be directly sent to the station controller by the main rail control system. Based on these two data, the preset opening time T of the corresponding branch rail entry valve can be calculated.

[0046] Taking into account that the running speed of the main rail may change in actual work, for example, the actual running speed of the main rail becomes faster, then after the preset opening time T, the actual vehicle has passed the branch rail to be entered. At this time, opening the branch rail entry valve will not allow the vehicle to enter the branch rail. Therefore, in order to ensure that this problem is avoided, the preset opening time T of the branch rail entry valve can also be set to be smaller to ensure that the vehicle is in front of or just at the corresponding branch rail after the preset opening time T.

[0047] This solution only requires one entry card reader, and there is no need to set up an entry card reader at the front end of each branch rail. The timing for the vehicle to enter the corresponding branch rail is calculated and controlled by software algorithms, which simplifies the structure, reduces costs, and makes the control more flexible through the control method of software algorithms.

[0048] like Figure 3 As shown, this embodiment is described by taking two branch rails as an example, namely branch rail 1 and branch rail 2. Of course, the number of branch rails can be three or more as needed. This workstation formed by the structure of multiple branch rails entering the station and multiple branch rails caching is mainly for more flexible switching of process flow in actual production. Multiple different production processes are arranged in parallel in one workstation to be suitable for urgent task insertion, or combined pairing production.

[0049] The specific control workflow is as follows: Figure 2 As shown, the details are as follows:

[0050] The station entry card reader 1 detects in real time whether there is a vehicle on the main rail. When the station entry card reader 1 detects a vehicle, the vehicle information on the vehicle is read and sent to the station controller. The station controller determines whether the vehicle needs to enter branch rail one based on the vehicle information. When it needs to enter branch rail one, the station controller calculates or calls the pre-stored branch rail one station entry valve 2 preset opening time T, and starts timing T1 at the same time. When T1 reaches T, that is, when they are equal, the station controller detects whether there is a branch rail one station entry full station photoelectric 3 signal on branch rail one. If so, the branch rail one station entry valve 2 is controlled to continue to remain closed and not open, and the vehicle does not enter the branch rail but continues to run on the main rail. If not, the branch rail one station entry valve 2 is controlled to open to allow the vehicle to enter the branch rail. If the vehicle does not need to enter branch rail 1, but needs to enter branch rail 2, the station controller calculates or calls the preset opening time T of branch rail 2 station entrance valve 4, and starts timing T1 at the same time. When T1 reaches T, that is, when they are equal, the station controller detects whether there is a branch rail 2 station entrance full station photoelectric 5 signal on branch rail 2. If there is, the branch rail 2 station entrance valve 4 is controlled to continue to remain closed and not open, and the vehicle does not enter the branch rail and continues to run on the main rail. If there is no signal, the branch rail 2 station entrance valve 4 is controlled to open to allow the vehicle to enter the branch rail. If the vehicle does not need to enter branch rail 1 or branch rail 2, the vehicle continues to run on the main rail.

[0051] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0052] Since a single entry card reader combined with a software algorithm is used for precise control, only one entry card reader is required and the installation position requirement for the entry card reader is low. Therefore, the defect that an entry card reader must be installed on each branch rail, resulting in a complex structure and high cost, especially when there is no space at the front end of the branch rail, the entry card reader cannot be installed, is effectively solved. The beneficial effects of simplifying the structure, reducing costs and having low requirements for the installation position of the entry card reader so that there will be no situation where there is no space and it cannot be installed, are achieved.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
