Description

Technical Field

[0001] The invention relates to a control method for a clothing production line, in particular to an entry and exit control method for clothing production hanging equipment and a control system adopting the control method. Background Art

[0002] In recent years, the emergence of clothing production hanging assembly lines has completely changed the traditional production model, realized the automated control of the processing process, improved production efficiency, and facilitated production management.

[0003] The garment production hanging assembly line generally includes a closed main track, multiple workstations arranged below the main track, each workstation is provided with a workstation branch track that can be connected to the main track, the entry end of the workstation branch track is provided with an entry actuator, the entry actuator can connect the entry end of the workstation branch track with the main track, the exit end of the workstation branch track is provided with an exit actuator, the exit actuator can connect the exit end of the workstation branch track with the main track, and multiple push rods and hangers are arranged on the main track. The push rods push the hangers on the main track to run in the specified direction under the drive mechanism. An entry card reader is arranged on the main track in front of the entry actuator, and an exit card reader is arranged on the workstation branch track in front of the exit actuator. The garment production hanging assembly line is also provided with a control center. The hangers and push rods are equipped with smart hangers with electronic tags. The control center reads the internal information of the electronic tags on the smart hangers through the entry card reader and the exit card reader to control the execution actions of the entry actuator and the exit actuator. The traditional push rod positioning method needs to rely on sensor equipment such as photoelectric sensors and encoders to calculate the initial position of the entire track push rod and the offset during movement. The method is costly and complex in calculation.

[0004] The Chinese invention patent with authorization announcement number CN 110442101 B (patent number ZL201910724135.5) discloses a method for controlling the exit of a hanging assembly line. The method discloses that when the exit card reader reads the hanger information, a signal "there is a hanger that needs to exit" is sent to the control center. The control center determines whether the push rod currently passing through the entry card reader is empty. If it is empty, the control information controls or controls the exit actuator through the communication data controller to drive the hanger out of the station. The hanger pushed out of the station by the push rod moves on the main track. The control center associates the push rod number of the push rod with the hanger number of the hanger; otherwise, it does not exit the station; after the hanger completes exiting the station, the exit actuator stops running. In this scheme, the specific method for determining whether the push rod currently passing through the entry card reader is empty is as follows: the entry card reader reads the push rod number passing through the entry card reader and uploads it to the main computer of the control center, and the main computer of the control center checks whether the push rod number is associated with a hanger number; if not, the push rod is empty; if so, the main computer of the control center determines whether the hanger associated with the push rod enters the station, and if so, the push rod is also empty. There are two defects in the above control method:

[0005] 1. The entry card reader, exit card reader, entry actuator and exit actuator are all connected to the main computer of the control center. When arranging the communication link, most of them use RS485 communication technology or CAN bus to communicate with the host computer. This communication mode has the disadvantages of relatively low communication distance, communication rate and bandwidth, which cannot meet the communication requirements of long distance and big data, and cannot realize the transmission of large files such as video. At the same time, the uploading and sending of communication information is prone to large delays; especially when any of the card readers fails, it will cause confusion in the control of the push rods and hangers in the entire assembly line;

[0006] 2. The specific method for judging whether the push rod currently passing through the entry card reader is empty is: the main circuit of the control center inquires whether the "push rod number" and the "hanger number" are associated and bound, or the hanger of the "hanger number" associated and bound with a certain "push rod number" has entered the station. This method of judging whether the push rod is empty is too complicated, and because there may be a large "delay" in the communication method, the information may not be uploaded and issued in time, and it is easy for the "empty push rod" to pass the exit of the workstation branch track, but the hanger does not leave the station in time. When the hanger leaves the station, the next push rod it encounters happens to be a "non-empty" push rod, so there will be a "chaotic" situation where one push rod drives two hangers;

[0007] 3. The timing control of the "hanger" leaving the station is not accurate enough: the exit card reader reads the hanger information, and the hanger is located near the exit card reader. At this time, the information "there is a hanger that needs to leave the station" is sent to the main computer of the control center through the exit card reader. Then the main computer of the control center determines whether the push rod currently passing through the entry card reader is empty. If it is empty, the control information is controlled or the communication data controller is used to control the exit actuator to drive the hanger out of the station. However, there is often a certain distance between the entry card puncher and the exit of the workstation branch track. It takes a certain amount of time for the push rod to run in this distance. This control method is also prone to the above-mentioned "empty push rod" having passed the exit of the workstation branch track, but the hanger has not left the station in time. When the hanger leaves the station, the next push rod it encounters happens to be a "non-empty" push rod, so there will be a "chaotic" situation in which one push rod drives two hangers.

[0008] Therefore, the prior art needs to be further improved. Summary of the invention

[0009] The primary technical problem to be solved by the present invention is to provide a method for controlling the entry and exit of clothing production hanging equipment with a simple control method and low cost in view of the above-mentioned prior art.

[0010] A further technical problem to be solved by the present invention is to provide an entry and exit control system for clothing production hanging equipment with a simple control method and low cost in view of the above-mentioned prior art.

[0011] The technical solution adopted by the present invention to solve the above-mentioned primary technical problem is: a method for controlling entry and exit of clothing production hanging equipment, wherein the clothing production hanging equipment control system includes a main track, multiple workstations below the main track, each workstation is provided with a workstation branch track that can be connected to the main track, the entry end of the workstation branch track is provided with a rotatable entry swing head, the entry swing head is driven and connected to the entry actuator, the entry actuator can drive the entry swing head to rotate so as to connect the entry end of the workstation branch track with the main track, the exit end of the workstation branch track is provided with a rotatable exit swing head, the exit swing head is driven and connected to the exit actuator, the exit actuator can drive the exit swing head to rotate so as to connect the exit end of the workstation branch track with the main track; multiple hanging devices are arranged on the main track, the hanging devices include a push rod and a hanger, and the push rod can be driven by the driving mechanism The hangers on the main track are pushed to run on the main track in the specified direction; an entry card reader is provided on the main track in front of the entry end of each workstation branch track, and an electronic tag with a unique ID code is provided on each push rod and hanger; it is characterized in that: each workstation is provided with a workstation control module, the corresponding entry card reader on the main track in front of the entry end of each workstation branch track is communicated with the corresponding workstation control module, and the entry actuator corresponding to the entry end of each workstation branch track and the exit actuator corresponding to the exit end of each workstation branch track are communicated with the corresponding workstation control module; the electronic tag ID codes of all push rods and the electronic tag ID codes of hangers required by this workstation are pre-stored in each workstation control module; the entry and exit control method of the clothing production hanging equipment includes an entry control method and an exit control method;

[0012] The entry control method of the entry and exit control method comprises: whenever the entry card reader reads a new electronic tag ID code, the electronic tag ID code is sent to the corresponding workstation control module, the workstation control module determines whether the electronic tag ID code is the electronic tag ID code of the clothes hanger that needs to enter the workstation, if so, the hanging device corresponding to the electronic tag ID code is the clothes hanger that needs to enter the workstation, at this time, the workstation control module controls the corresponding entry actuator to connect the entry end of the workstation branch track with the main track, so that the clothes hanger corresponding to the electronic tag ID code enters the workstation branch track; if not, the entry card reader continues to read the next new electronic tag ID code and repeats the judgment;

[0013] The exit control method of the entry and exit control method includes: when a clothes hanger to be exited is provided on the workstation branch track, the workstation control module continuously determines whether the hanging device passing through the entry card reader is an "idle push rod". If it is an "idle push rod", when the "idle push rod" moves close to the exit end of the workstation branch track, the workstation control module controls the corresponding exit actuator to connect the exit end of the workstation branch track with the main track, so that the clothes hanger to be exited on the workstation branch track enters the main track, and the clothes hanger is located in front of the "idle push rod".

[0014] As an improvement, the method for the workstation control module to determine whether the hanging device passing through the entry card reader is an "idle push rod" is as follows: the entry card reader continuously reads the electronic tag ID code of each hanging device passing through the entry card reader, and sends the read electronic tag ID code to the workstation control module. Each time the workstation control module receives an electronic code tag ID code, it performs the following operation steps to make a judgment:

[0015] Step 1: determine whether the electronic tag ID code is the electronic tag ID code of the hanger. If it is the electronic tag ID code of the hanger, record the time when the entry card reader reads the electronic tag ID code, and then proceed to step 2; if it is not the electronic tag ID code of the hanger, the hanging device corresponding to the electronic tag ID code is the push rod, and proceed to step 3;

[0016] Step 2, the workstation control module continues to determine whether the electronic tag ID code is the electronic tag ID code of the clothes hanger required by the workstation. If the electronic tag ID code is the electronic tag ID code of the clothes hanger required by the workstation, the workstation control module controls the corresponding station entry actuator to connect the station entry end of the workstation branch track with the main track, so that the clothes hanger corresponding to the electronic tag ID code enters the workstation branch track; if the electronic tag ID code is not the electronic tag ID code of the clothes hanger required by the workstation, the electronic tag ID code is ignored;

[0017] Step 3: The workstation control module subtracts the time of reading the electronic tag ID code from the time of the most recently acquired electronic tag ID code of the hanger to obtain △t3, compares the shortest distance between two adjacent push rods on the main track with the running speed of the push rods on the main track to obtain △t, and determines whether △t3 is less than △t. If so, proceed to step 4; if not, set the hanging device where the electronic tag ID code is located as "idle push rod";

[0018] Step 4, the workstation control module determines whether the hanger corresponding to the electronic tag ID code of the hanger closest to the time of obtaining the electronic tag ID has entered this workstation. If not, the hanging device where the electronic tag ID code is located is set to a "busy push rod". If so, the hanging device where the electronic tag ID code is located is set to an "idle push rod".

[0019] Further improvement, when the workstation control module determines that the hanging device corresponding to a certain electronic tag ID code is the electronic tag ID code of the hanger that needs to enter the workstation, the workstation control module obtains the entry waiting time required for the hanger to enter the station through the ratio of the distance between the entry card reader and the entry actuator and the running speed of the main track push rod. After the entry waiting time expires, the workstation control module controls the entry actuator to connect the entry end of the workstation branch track with the main track, so that the hanger corresponding to the electronic tag ID code enters the workstation branch track.

[0020] Further improvement, when there is a hanger to be exited on the workstation branch track, and the workstation control module determines that the hanging device currently passing the entry card reader is an "idle push rod", the workstation control module obtains the exit waiting time for the "idle push rod" to reach the exit end of the workstation branch track through the ratio of the distance between the entry card reader and the exit end of the corresponding workstation branch track and the running speed of the main track push rod. According to the exit waiting time, the workstation control module controls the corresponding exit actuator to connect the exit end of the workstation branch track with the main track, so that the hanger to be exited on the workstation branch track enters the main track, and the hanger is located in front of the "idle push rod".

[0021] The technical solution adopted by the present invention to solve the above-mentioned further technical problems is: a clothing production hanging equipment control system, characterized in that: the above-mentioned clothing production hanging equipment control system adopts the above-mentioned entry and exit control method of the clothing production hanging equipment control system to perform operation control.

[0022] Compared with the prior art, the advantages of the present invention are: a workstation control module is set at each workstation, and the workstation control module only needs to pay attention to the electronic tag ID code information read by the corresponding entry card reader on the main track in front of the entry end of the workstation branch track, and can control entry and exit according to the read electronic tag ID code; in the improved scheme of judging whether the hanging device currently passing through the entry card reader is an "idle push rod", by comparing the distance between the hanging devices where two adjacent electronic tags are located with the shortest distance between the two push rods on the main track, it is possible to infer whether there is an "idle push rod", the judgment method is simple, no exit card reader needs to be set, and the cost is low.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 The control system of the clothing production hanging equipment shown in the figure comprises a roughly closed main track 1, a plurality of workstations 2 are arranged below the main track 1, a workstation branch track 3 which can be connected to the main track is arranged above each workstation 2, an inlet end of the workstation branch track 3 is provided with a rotatable inlet swing head 10, the inlet swing head 10 is drivingly connected to the inlet actuator 4, the inlet actuator can drive the inlet swing head 10 to rotate so as to connect the inlet end of the workstation branch track 3 with the main track 1, an outlet swing head 9 is arranged at the outlet end of the workstation branch track, the outlet swing head 9 is drivingly connected to the outlet actuator 5, the outlet actuator 5 can drive the outlet swing head 9 to rotate so as to connect the outlet end of the workstation branch track 3 with the main track 1; a plurality of hanging devices are arranged on the main track 1, the hanging devices comprise a push rod 6 and a hanger 7, the push rod 6 can be driven when driving Driven by the mechanism, the hangers on the main track 1 are pushed to run on the main track 1 in the specified direction; an entry card reader 8 is set on the main track 1 in front of the entry end of each workstation branch track 3, and an electronic tag with a unique ID code is set on each push rod and hanger; each workstation 2 is provided with a workstation control module 21, and the corresponding entry card reader 8 on the main track in front of the entry end of each workstation branch track is communicated with the corresponding workstation control module 21, and the entry actuator 4 corresponding to the entry end of each workstation branch track 3 and the exit actuator 5 corresponding to the exit end of each workstation branch track are communicated with the corresponding workstation control module 21; each workstation control module pre-stores the electronic tag ID codes of all push rods and the electronic tag ID codes of the hangers required by this workstation. The entry actuator 4, the exit actuator 5 and the driving mechanism adopt existing conventional technology. The workstation control module 21 corresponding to each workstation is connected to the host computer of the main control center for communication. The electronic tag ID codes of all push rods and the electronic tag ID codes of the hangers required by this workstation, which are pre-stored in the workstation control module 21, can be sent in advance by the host computer of the main control center, or can be separately entered in the workstation control module 21. In addition, the workstation control module 21 corresponding to each workstation stores the shortest distance L between two adjacent push rods on the main track, the running speed V of the push rod pushed by the main track, the distance L1 between the corresponding entry card reader 8 on the main track 1 in front of the entry end of each workstation branch track 3 and the entry end of the corresponding workstation branch track 3, and the distance L2 between the corresponding entry card reader 8 and the exit end of the corresponding workstation branch track 3. These data can be sent in advance by the host computer of the main control center, or can be separately entered in the workstation control module 21.

[0027] The entry and exit control method of the hangers at each workstation in the above-mentioned clothing production hanging equipment control system includes an entry control method and an exit control method. The workstation control module 21 in each workstation 2 will run the above-mentioned entry and exit control method, and when each workstation control module executes the entry control method and the exit control method, the two control methods run independently at the same time without affecting each other.

[0028] The station entry control method in the station entry and exit control method includes: the station entry card reader continuously reads the electronic tag ID code of each hanging device passing through the station entry card reader, and sends the read electronic tag ID code to the workstation control module. The workstation control module performs the following operation steps for judgment every time it receives an electronic tag ID code: the workstation control module judges whether the electronic tag ID code is the electronic tag ID code of the clothes hanger that needs to enter the workstation. If so, the hanging device corresponding to the electronic tag ID code is the clothes hanger that needs to enter the workstation. At this time, the workstation control module obtains the waiting time △t1 required for the hanger to enter the station through the ratio of the distance between the station entry card reader and the station entry end of the corresponding workstation branch track 3 and the running speed of the main track push rod. After the waiting time △t1 expires, the workstation control module controls the station entry actuator to work, and the station entry actuator 4 drives the station entry swing head 10 to rotate to connect the station entry end of the workstation branch track with the main track, so that the hanger corresponding to the electronic tag ID code enters the workstation branch track; if not, the workstation control module determines the next electronic tag ID code;

[0029] The exit control method in the entry and exit control method includes: a hanger exit touch switch can be set in the workstation, and the hanger exit touch switch is connected to the workstation control module 21 for communication. When the hanger exit touch switch is triggered, the workstation control module 21 can know that a hanger to be exited is arranged on the workstation branch track; when a hanger to be exited is arranged on the workstation branch track, the workstation control module continuously determines whether the hanging device passing through the entry card reader is an "idle push rod". If it is an "idle push rod", the workstation control module passes the entry card reader to the workstation control module. The ratio of the distance between the card reader and the exit end of the corresponding workstation branch track to the running speed of the main track push rod is obtained to obtain the exit waiting time △t2 for the "idle push rod" to reach the exit end of the workstation branch track. The workstation control module 21 controls the corresponding exit actuator 5 to work according to the exit waiting time △t2. The exit actuator 5 drives the exit swing head 9 to rotate to connect the exit end of the workstation branch track with the main track, so that the hanger 7 to be exited on the workstation branch track enters the main track and the hanger is located on the front side of the "idle push rod".

[0030] The method by which the workstation control module determines whether the hanging device passing through the entry card reader is an "idle push rod" is as follows: the entry card reader continuously reads the electronic tag ID code of each hanging device passing through the entry card reader, and sends the read electronic tag ID code to the workstation control module. The workstation control module performs the following steps to determine each time it receives an electronic code tag ID code:

[0031] Step 1: determine whether the electronic tag ID code is the electronic tag ID code of the hanger. If it is the electronic tag ID code of the hanger, record the time when the entry card reader reads the electronic tag ID code, and then proceed to step 2; if it is not the electronic tag ID code of the hanger, the hanging device corresponding to the electronic tag ID code is the push rod, and proceed to step 3;

[0032] Step 2, the workstation control module continues to determine whether the electronic tag ID code is the electronic tag ID code of the clothes hanger required by the workstation. If the electronic tag ID code is the electronic tag ID code of the clothes hanger required by the workstation, the workstation control module controls the corresponding station entry actuator to connect the station entry end of the workstation branch track with the main track, so that the clothes hanger corresponding to the electronic tag ID code enters the workstation branch track; if the electronic tag ID code is not the electronic tag ID code of the clothes hanger required by the workstation, the electronic tag ID code is ignored;

[0033] Step 3: The workstation control module subtracts the time of reading the electronic tag ID code from the time of the most recently acquired electronic tag ID code of the hanger to obtain △t3, compares the shortest distance between two adjacent push rods on the main track with the running speed of the push rods on the main track to obtain △t, and determines whether △t3 is less than △t. If so, proceed to step 4; if not, set the hanging device where the electronic tag ID code is located as "idle push rod";

[0034] Step 4, the workstation control module determines whether the hanger corresponding to the electronic tag ID code of the hanger closest to the time of obtaining the electronic tag ID has entered this workstation. If not, the hanging device where the electronic tag ID code is located is set to a "busy push rod". If so, the hanging device where the electronic tag ID code is located is set to an "idle push rod".

[0035] The entry and exit control method in this embodiment does not require the installation of an exit card reader. Each workstation control module operates independently and does not need to communicate with the host computer of the control center. This ensures good real-time performance. The control method is simple, reliable and low-cost.
