[0024] Example 1

[0025] Reference Figures 1 to 5, is an embodiment of the utility model, which provides a clothing needle detection device with a screening function, including a workbench 101, a transmission member 104 is provided on the workbench 101, a detector 103 is provided across the top of the transmission member 104, the bottom of the detector 103 is arranged on the workbench 101, the workbench 101 is suspended on the ground through a support member, and a limiting component 200 is provided at one end of the workbench 101 located at the outlet end of the transmission member 104, the limiting component 200 includes a baffle 201, the bottom of the baffle 201 is rotatably arranged on the workbench 101, when the detector 103 alarms, the baffle 201 rotates so that its top is higher than the surface of the transmission member 104, the outer surface of the baffle 201 cooperates with the transmission member 104 to guide the clothing, and then the baffle 201 is immediately reversed so that it is against the surface of the transmission member 104, and the clothing is separated from the outer surface of the baffle 201.

[0026] Specifically, the workbench 101 is the bearing platform of the entire device, and the workbench 101 is suspended from the ground at a certain height to facilitate workers' operation and the sorting of clothing. The transmission member 104 is installed on the upper surface of the workbench 101, and the transmission member 104 transmits clothing in a unidirectional manner during the needle inspection process. The detector 103 is usually a device used to detect whether there are broken needles or other ferromagnetic metal impurities in sewn products, and is widely used in clothing, textiles, footwear and other industries. The device receives and processes signals through upper and lower probes, and uses strong magnetic field induction and photoelectric scanning induction to complete the detection work. The device includes upper and lower probes, strong magnetic field induction, photoelectric scanning induction, strong electric integrated block, sensitivity control integrated block, signal receiving integrated block and signal output integrated block; specific working principle:

[0027] Signal reception and processing: The upper and lower probes (detection sensors) receive and process signals;

[0028] Strong magnetic field induction: When a ferromagnetic object enters the detection channel, the upper and lower probes generate signals through strong magnetic field induction;

[0029] Photoelectric instrument scanning induction: The photoelectric instrument scans and senses the signal;

[0030] Signal processing: The signal is sent to the signal receiving and processing integrated block, and then the detection work is completed through the strong current integrated block, sensitivity control integrated block, signal receiving integrated block and signal output integrated block;

[0031] Components: Detection sensor (probe): It is composed of an upper detection sensor and a lower detection sensor, forming a height through which detection objects of different specifications can pass, referred to as the detection height;

[0032] Conveyor belt: used to transport items into the inspection area;

[0033] Strong magnetic field induction system: includes magnets and injection coils in the upper and lower probes, powered by the machine power supply.

[0034] Photoelectric instrument: used to scan the sensing signal;

[0035] Integrated block: including high-voltage integrated block, sensitivity control integrated block, signal receiving integrated block and signal output integrated block, used for processing and outputting signals;

[0036] The detector 103 is across the transmission member 104. When the transmission member 104 transmits the clothing, it is detected by the detector 103. The transmission member 104 leads one end of the clothing. A limit assembly 200 is provided on the workbench 101. The limit assembly 200 is mainly installed on the workbench 101 by rotating the bottom of the baffle 201. When the detector 103 detects that there is metal in the clothing, the baffle 201 is slightly lifted by manual or driving structure, and the clothing is transferred from the surface of the transmission member 104 to the outer surface of the baffle 201, and has an upward trend and The outer surface friction of the baffle 201 shortens the landing distance of the clothing after it is separated from the transmission element 104. At this time, the baffle 201 is immediately reversed to allow the qualified clothing to be thrown normally after it is separated from the transmission element 104. For this reason, the clothing with broken needles, metal powder, pins and other residues is sorted. In this process, the transmission element 104 does not stop or reverse. The worker only needs to put the clothing to be inspected for needles on the transmission element 104 of the device with normal spacing. Compared with the common clothing needle inspection equipment, this equipment greatly improves the effect of needle inspection of packaged clothing;

[0037] In order to realize the controllability of the rotation of the baffle 201, method 1: manually rotating the baffle 201, when the unqualified clothing arrives at the outlet end of the transmission member 104, the baffle 201 is lifted to allow the clothing to be guided out of the baffle 201, and then the baffle 201 is retracted;

[0038] Method 2: The limit assembly 200 also includes a shaft 202, a bearing 203 and a servo motor 204. The servo motor 204 is electrically connected to the switch through an electric wire. The servo motor 204 is arranged on the workbench 101. The output shaft of the servo motor 204 is connected to the shaft 202. Both ends of the shaft 202 are arranged on the workbench 101 through the shaft 202. The shaft 202 passes through the locking hole 201e at the bottom of the baffle 201. The guide surface 201a of the baffle 201 cooperates with the transmission member 104. The support surface 201b of the baffle 201 is concave in the guide surface 201a, and a cavity 201c is provided between the guide surfaces 201a and the guide surfaces 201a. The output shaft of the servo motor 204 can rotatably install the shaft rod 202 to penetrate the locking hole 201e at the bottom of the baffle 201 and lock the baffle 201. Under the drive of the servo motor 204, the baffle 201 can be rotated forward and backward. The surface of the guide surface 201a is roughened to increase the friction between the clothing and the guide surface 201a. The support surface 201b is concave toward the guide surface 201a to reduce the volume of the block 201 and reduce the self-weight. The concave structure also improves the overall support strength of the block 201. The cavity 201c on the block 201 also reduces its self-weight, allowing the block 201 to be easily turned over and more firmly supporting the clothing. The switch on the servo motor 204 can be configured with a limit switch. Specifically;

[0039] Configure limit switch: Install limit switch in the servo motor control system to detect the position of the servo motor. When the servo motor reaches the preset position, the limit switch will be triggered;

[0040] Writing control programs: Use PLC (such as Siemens S7-1200) to write control programs. You can use ladder diagrams or high-level programming languages ​​(such as SCL) to write programs;

[0041] Set the start and stop instructions, as well as the speed target value in the program;

[0042] Write position control logic to perform a reverse operation when a preset position is reached;

[0043] Adjust parameters: Set the servo motor speed target and brake device to ensure a quick and safe stop;

[0044] Adjust the PLC sampling period and control algorithm to balance accuracy and stability;

[0045] Through the above steps, the stopper 201 connected to the servo motor 204 can be started, reversed and stopped in a short time to sort the clothes.

[0046] Furthermore, a support leg 102 is provided at the bottom of the workbench 101, and the workbench 101 forms a certain height with the ground through the support leg 102. A guide block 105 is provided on the workbench 101, and the top of the guide block 105 is rotatably connected to one end of a bracket 105a. The guide block 105 allows the clothing to be transferred at the middle position on the transmission member 104, and the position can be adjusted to meet the needs of clothing packaged in different sizes. The other end of the guide block 105 and the bracket 105a are connected to the workbench 101, and the transmission member 104 is composed of a belt 104a, a transmission shaft 104b and a driving motor arranged on the two transmission shafts 104b. The transmission shaft 104b is arranged on the workbench 101, and the outer surfaces of the two transmission shafts 104b are sleeved with the belt 104a. The transmission member 104 is used to transmit clothing in the form of a belt and a transmission shaft. The efficiency of clothing needle inspection can be flexibly adjusted by regulating the belt book removal rate through the driving motor.

[0047] Example 2

[0048] This is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the switch of the servo motor 204 is integrated into the signal processing module of the detector 103;

[0049] Specific;

[0050] Signal reception and processing: First, it is necessary to ensure that the needle detector can generate an alarm signal. This can be achieved by designing a strong electric integrated block, which is responsible for receiving and processing signals from the upper and lower probes. These probes detect whether there are foreign objects or broken needles through strong magnetic field induction and photoelectric scanning induction;

[0051] Signal output: Design a signal output integrated block to convert the detected abnormal situation (such as broken needle) into an alarm signal. This signal output integrated block is key because it directly affects the subsequent operation process;

[0052] Servo motor control system integration: Using Siemens S7-1200 PLC as the control core, the PLC can be configured to receive alarm signals from the needle detector and control the servo motor according to a preset program. In the Siemens S7-1200 PLC, a specific input port can be set to receive the alarm signal from the needle detector and programmatically start the servo motor when the alarm signal appears.

[0053] Servo motor driver configuration: Ensure that the servo motor driver is configured correctly so that it can start the servo motor promptly and accurately when receiving the start signal from the PLC. The servo motor driver should have the characteristics of high-speed performance, low heat and vibration, and can output alarm signals in time when continuously overloaded.

[0054] System testing and debugging: After completing all hardware and software configurations, conduct comprehensive system testing and debugging to ensure that in the actual production environment, the alarm signal of the needle detector can accurately trigger the start of the servo motor;

[0055] It is worth mentioning that when the detector 103 detects that the clothing has broken needles, metal powder, thumbtacks, etc., the servo motor 204 is immediately turned on by the switch and stays for a set time. At this time, the servo motor 204 drives the block 201 to rotate the guide clothing, and then reverses and stops working. It should be noted here that the packaged clothing to be inspected must be placed on the transmission member 104 with a larger spacing to avoid sorting qualified clothing into unqualified clothing.

[0056] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure of performing the function described herein, and is not only structurally equivalent but also equivalent structure. Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0057] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0058] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
