Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a loop detection device for detecting the tension of the neckline, cuffs, etc. of clothes. Background Art

[0002] T-shirts are one of the favorite clothing items in spring and summer. T-shirts have become popular seasonal clothing due to their natural, comfortable, stylish yet solemn characteristics. The neckline of a T-shirt can best reflect the quality of a piece of clothing. A good piece of clothing will not turn up the collar or wrinkle even after being worn many times. Ordinary cotton-bound collars and ordinary ribbed collars are prone to deformation. To avoid neckline deformation, higher-end T-shirts usually choose nylon-blended necklines or pure cotton thickened ribbed collars. T-shirts with such necklines look more delicate and are also more wash-resistant. Different necklines have different elasticities. To ensure that people can smoothly put on the T-shirt from the head, it is necessary to detect the elasticity of the neckline. Currently, the elasticity of the neckline is tested manually. Workers put the T-shirt on a waist-shaped loop (the waist-shaped loop is arranged along the vertical direction) from top to bottom, and pull it down so that the neckline passes through the waist-shaped loop. Passing through means it is qualified. Since everyone has different strength, there may be a problem that some people can pull it through while others cannot for the same T-shirt to be detected, resulting in poor reliability of this manual detection. Chinese patent document CN100420932C discloses a "neckline stretching tester for elastic fabrics such as wool sweaters". This tester needs to clamp the clothing on the movable chuck and the fixed chuck, and it also needs to be manually taken out after the test. The installation is troublesome and the efficiency is too low. Secondly, the tester can only detect the elasticity of the part clamped by the movable chuck and the fixed chuck, and cannot detect the overall elasticity. Summary of the Invention

[0003] The purpose of the present invention is to provide a loop detection device for detecting the tension of the neckline, cuffs, etc. of clothes, which has a simple structure and is beneficial to improving the detection efficiency.

[0004] The basic technical solution to achieve the purpose of the present invention is: a loop detection device, including a frame. Its structural feature is that: it further includes a detection mechanism and a turntable component. The frame is provided with two or more workstations at equal angular intervals along the circumference. The turntable component includes a turntable seat plate and a mounting frame. The mounting frame is provided with workstations corresponding to the workstations of the frame. The mounting frame is rotatably arranged on the turntable seat plate, and the turntable seat plate is fixedly arranged on the frame. The number of groups of the detection mechanism is the same as the number of workstations of the mounting frame. Each group of detection mechanisms is respectively fixedly arranged on the corresponding workstations of the rotary frame.

[0005] The structures of each group of detection mechanisms are the same. Each detection mechanism includes a material supporting rod, a material supporting motor, a weighing sensor, and a mounting seat. The mounting seat is fixedly arranged on the corresponding workstation of the mounting frame of the turntable component. The material supporting rod includes a fixed material supporting rod and a movable material supporting rod.

[0006] The load cell is fixedly mounted on the left end of the mounting base, and the fixed support rod is fixedly mounted on the load cell. The support motor is fixedly mounted on the left side of the mounting base. The movable support rod is slidably mounted on the mounting base in the left-right direction, and the support motor drives the movable support rod to move closer to or away from the fixed support rod.

[0007] To prevent clothing from slipping off the support rod during testing, the testing mechanism also includes an anti-slip component. There are two sets of anti-slip components, each set including at least one O-ring. The O-ring of one set of anti-slip components is fitted onto the front of the fixed support rod, and the O-ring of the other set of anti-slip components is fitted onto the front of the movable support rod.

[0008] To improve testing efficiency and ensure the reliability of the moving support rod during operation, the testing mechanism also includes a transmission assembly and a testing guide assembly. The testing guide assembly includes a linear guide rail, which is fixedly mounted on the mounting base along the left-right direction. The moving support rod is fixedly mounted on the slider of the linear guide rail, and is driven by a support motor through the transmission assembly to move the moving support rod left and right along the linear guide rail of the testing guide assembly.

[0009] To improve work efficiency and ensure automatic switching of workstations, the turntable assembly also includes a turntable base, a rotating shaft, a rotary drive motor, and a rotary transmission assembly.

[0010] The turntable base is fixedly mounted on the center of the turntable base plate. The mounting bracket is rotatably mounted on the upper end of the turntable base via crossed roller bearings. The lower part of the rotating shaft is rotatably mounted in the lower part of the turntable base via deep groove ball bearings, and the upper end of the rotating shaft is fixedly connected to the mounting bracket. A rotary drive motor drives the rotating shaft to rotate through a rotary transmission assembly. The rotating shaft drives the mounting bracket to rotate for workstation switching, ensuring smooth and efficient operation.

[0011] To improve efficiency and achieve automated material collection, a material collection mechanism is also included. There are two sets of material collection mechanisms. The frame has three stations arranged at equal intervals along its circumference. These three stations, from the front edge counter-clockwise, are named the inspection station, the finished product collection station, and the defective product collection station. The two sets of material collection mechanisms are respectively located at the finished product collection station and the defective product collection station on the frame.

[0012] Furthermore, both sets of receiving mechanisms have the same structure, each including a receiving base, a feeding rack, a feeding rack drive device, a receiving guide assembly, and a clamping rack. The receiving base is fixedly mounted on the lower part of the frame. The feeding rack is radially slidable on the receiving base along the rotation axis, and the feeding rack drive device drives the feeding rack to move radially along the rotation axis. The clamping rack is fixedly mounted on the turntable base plate.

[0013] Furthermore, to accommodate the increasing thickness after material collection, the feeding rack drive device includes a drive cylinder and a buffer. The drive cylinder is fixedly mounted on the receiving base by its cylinder body. The buffer includes a connecting sleeve, a connecting rod, a buffer spring, and a limiting pin. The connecting rod is arranged in a direction parallel to the radial direction of the rotation axis, and its outer end is fixedly mounted on the lower part of the feeding rack. The corresponding part of the inner end of the connecting rod is located in the connecting sleeve. The buffer spring is sleeved on the connecting rod, and the limiting pin is fixedly mounted on the inner end of the connecting rod. The outer end of the buffer spring is limited in the connecting sleeve by the corresponding part of the connecting sleeve, and the inner end of the buffer spring is limited in the connecting sleeve by the limiting pin. The end of the cylinder rod of the drive cylinder is fixedly connected to the inner end of the connecting sleeve.

[0014] In order to efficiently remove the tested garments from the support rod, the receiving mechanism also includes a picking device. The picking device includes a blowing air pipe with an air outlet along the axial direction. The air outlet is arranged radially outward along the blowing air pipe. The air outlet blows air to blow the tested garments off the testing device onto the feeding rack. The structure is simple and the efficiency is high.

[0015] Furthermore, to ensure the garments fall flat onto the clamping rack, a guiding assembly is provided. This assembly includes two guide rods, both fixedly mounted on the turntable. One guide rod is located between the inspection station and the finished product receiving station, its outer end extending radially outward along the rotation axis to the outside of the clamping rack at the corresponding finished product receiving station. The other guide rod is located between the finished product receiving station and the defective product receiving station, its outer end extending radially outward along the rotation axis to the outside of the clamping rack at the corresponding defective product receiving station.

[0016] The present invention has the following beneficial effects: (1) The ring detection device of the present invention has a simple structure and is provided with detection station, finished product receiving station and defective product receiving station. Workers only need to put the garment to be tested on the detection device located at the detection station, and then the receiving mechanism of the corresponding finished product receiving station or defective product receiving station will collect the garment, which greatly improves the detection efficiency and greatly enhances the reliability and consistency compared with manual detection.

[0017] (2) The detection mechanism of the ring detection device of the present invention is provided with a fixed support rod and a movable support rod. The support rod is provided with an anti-slip component, which makes the installation convenient and quick and prevents the clothing from falling off.

[0018] (3) The detection mechanism of the ring detection device of the present invention is equipped with a detection guide component, the moving support rod runs smoothly and has good support force, which is conducive to improving the reliability of detection.

[0019] (4) The feeding rack drive device of the feeding mechanism of the ring detection device of the present invention is equipped with a buffer, which can adapt to the continuous increase of the clothing being fed, and at the same time play a buffering role when running inward, reducing the impact on the equipment and ensuring good stability.

[0020] (5) The material receiving device of the ring detection device of the present invention uses air blowing to make the fabric drape on the feeding rack, which has a simple structure and high efficiency.

[0021] (6) The ring detection device of the present invention is provided with a material guiding component. When the turntable component rotates, it facilitates the entry of clothing into the clamping rack and the dispensing rack, so that the clothing falls flat on the clamping rack, making the collection more even, thereby improving the stability of clothing piled on the dispensing rack and facilitating the collection of more clothing.

The orientation of the invention is described according to... Figure 1 Proceeding in the indicated direction, that is Figure 1 The directions shown are the same as the directions described. The side closer to the center is called the inner side, and the side farther from the center is called the outer side.

[0040] (Example 1)

[0041] See Figures 1 to 11 The bead detection device of this embodiment includes a frame 1, a turntable assembly 2, a detection mechanism 3, a receiving mechanism 4, and a guiding assembly 5. The frame 1 has two or more stations arranged at equal intervals along its circumference. This embodiment has three stations, which are named, from the front edge counterclockwise, detection station 1a, finished product receiving station 1b, and defective product receiving station 1c. A feeding rod 1-1 is provided on the upper front side of the frame 1.

[0042] See Figures 1 to 8 The turntable assembly 2 includes a turntable base plate 2-1, a turntable base 2-2, a mounting bracket 2-3, a rotating shaft 2-4, a pneumatic-electric slip ring 2-5, a rotary drive motor 2-6, and a rotary transmission assembly 2-7.

[0043] Mounting frame 2-3 has the same number of workstations as the machine frame 1. In this embodiment, mounting frame 2-3 has three workstations, the same number as the machine frame 1. The three workstations of mounting frame 2-3 are positioned corresponding to the three workstations of machine frame 1.

[0044] A turntable base plate 2-1 is fixedly mounted on the upper part of the frame 1. A turntable base 2-2 is fixedly mounted on the middle part of the turntable base plate 2-1. A mounting bracket 2-3 is rotatably mounted on the upper end of the turntable base 2-2 via a crossed roller bearing 2-8. The lower part of a rotating shaft 2-4 is rotatably mounted in the lower part of the turntable base 2-2 via a deep groove ball bearing 2-9, and the upper end of the rotating shaft 2-4 is fixedly connected to the mounting bracket 2-3. The rotary transmission assembly 2-7 includes a reducer 2-71, a first driving wheel 2-72, a first driven wheel 2-73, and a first synchronous belt 2-74. The reducer 2-71 is fixedly mounted on the lower side of the turntable base plate 2-1, and a rotary drive motor 2-6 is fixedly mounted on the reducer 2-71. The motor shaft of the rotary drive motor 2-6 is connected to the input end of the reducer 2-71. The first driving wheel 2-72 is fixedly mounted on the output shaft of the reducer 2-71. The first driven wheel 2-73 is mounted on the lower end of the rotating shaft 2-4. The first synchronous belt 2-74 surrounds the first driving wheel 2-72 and the first driven wheel 2-73. Thus, the rotating shaft 2-4 is driven to rotate by the rotary drive motor 2-6 through the rotary transmission assembly 2-7. The rotating shaft 2-4 then drives the mounting bracket 2-3 to rotate for position switching. The rotary drive motor 2-6 is equipped with a stator anti-rotation rod 2-61. The stator of the pneumatic slip ring 2-5 is stopped and limited by the stator anti-rotation rod 2-61. The rotor of the pneumatic slip ring 2-5 is fixedly mounted on the lower end of the rotating shaft 2-4.

[0045] See Figures 1 to 5 , Figure 9 and Figure 10 The number of testing mechanisms 3 is the same as the number of workstations of the mounting frame 2-3. In this embodiment, there are three sets of testing mechanisms 3, which are fixedly installed on the three workstations of the rotating frame 2-2.

[0046] The three sets of detection mechanisms 3 have identical structures. Each set of detection mechanisms 3 includes a support rod 3-1, an anti-slip component 3-2, a support motor 3-3, a load cell 3-4, a transmission component 3-5, a detection guide component 3-6, and a mounting base 3-7. The load cell 3-4 is existing technology. In this embodiment, the load cell 3-4 is a column-type miniature load cell, model DYZ-101, from Bengbu Dayang Sensor System Engineering Co., Ltd.

[0047] The support rod 3-1 includes a fixed support rod 3-11 and a movable support rod 3-12.

[0048] There are two sets of anti-slip components 3-2, each set including at least one O-ring. In this embodiment, each set includes two O-rings, which are made of fluororubber. The two O-rings of one set of anti-slip components 3-2 are sequentially fitted onto the front of the fixed support rod 3-11 from front to back, and the two O-rings of the other set of anti-slip components 3-2 are sequentially fitted onto the front of the movable support rod 3-12 from front to back.

[0049] Mounting base 3-7 is fixedly installed on the corresponding position of mounting bracket 2-3 of turntable assembly 2. The right side of weighing sensor 3-4 is fixedly installed on the left end of mounting base 3-7, and the fixed support rod 3-11 is fixedly installed on the left side of weighing sensor 3-4.

[0050] The material support motor 3-3 is fixedly mounted on the left side of the mounting base 3-7. The movable material support rod 3-12 is slidably mounted on the mounting base 3-7 in a left-right direction. The material support motor 3-3 drives the movable material support rod 3-12 to move left and right through the transmission assembly 3-5, that is, drives the movable material support rod 3-12 to move closer to or away from the fixed material support rod 3-11. The transmission assembly 3-5 includes a second driving wheel, a second driven wheel, and a second synchronous belt. The second driving wheel is fixedly mounted on the motor shaft of the material support motor 3-3, and the second driven wheel is rotatably mounted on the right side of the mounting base 3-7. The second synchronous belt is arranged around the second driving wheel and the second driven wheel. The detection guide assembly 3-6 includes a linear guide rail, which is fixedly mounted on the mounting base 3-7 in the left-right direction. The movable support rod 3-12 is fixedly mounted on the slider of the linear guide rail. The slider of the linear guide rail is fixedly connected to the second synchronous belt of the transmission assembly 3-5 through a synchronous belt clamp. Thus, the support motor 3-3 drives the movable support rod 3-12 to move left and right along the linear guide rail of the detection guide assembly 3-6 through the transmission assembly 3-5.

[0051] See Figures 1 to 5 and Figure 11There are two sets of receiving mechanisms 4, both with identical structures, including a receiving base 4-1, a feeding rack 4-2, a feeding rack drive device 4-3, a receiving guide assembly 4-4, a clamping rack 4-5, and a picking device 4-6. The two sets of receiving mechanisms 4 are respectively located at the finished product receiving station 1b and the defective product receiving station 1c of the frame 1. The receiving base 4-1 is fixedly mounted on the lower part of the frame 1. The feeding rack 4-2 is radially slidably mounted on the receiving base 4-1 along the rotating shaft 2-4, and the feeding rack drive device 4-3 drives the feeding rack 4-2 to move radially along the rotating shaft 2-4. The upper part of the feeding rack 4-2 is T-shaped. The feeding rack drive device 4-3 includes a drive cylinder 4-31 and a buffer 4-32. The receiving guide assembly 4-4 includes two linear guide rails 4-41, each with two sliders. The four sliders of the two linear guides 4-41 are fixedly mounted on the feeding base 4-1 in a rectangular arrangement. The guides of the two linear guides 4-41 are arranged in a direction parallel to the radial direction of the rotation axis 2-4. The feeding rack 4-2 is fixedly mounted on the guides of the two linear guides 4-41.

[0052] The feeding rack drive device 4-3 includes a drive cylinder 4-31 and a buffer 4-32. The drive cylinder 4-31 is fixedly mounted on the receiving base 4-1 by its cylinder body, and its axis is parallel to the guide rail direction of the linear guide rail 4-41. The cylinder rod of the drive cylinder 4-31 extends outward, and the end of the cylinder rod is fixedly connected to the inner end of the connecting sleeve 4-321.

[0053] The buffer 4-32 includes a connecting sleeve 4-321, a connecting rod 4-322, a buffer spring 4-323, and a limiting pin 4-324. The connecting rod 4-322 is arranged in a direction parallel to the radial direction of the rotation axis 2-4, and its outer end is fixedly mounted on the lower part of the feeding rack 4-2. The corresponding part of the inner end of the connecting rod 4-322 is located in the connecting sleeve 4-321. The buffer spring 4-323 is sleeved on the connecting rod 4-322. The limiting pin 4-324 is fixedly mounted on the inner end of the connecting rod 4-322. The outer end of the buffer spring 4-323 is limited in the connecting sleeve 4-321 by the corresponding part of the connecting sleeve 4-321, and the inner end of the buffer spring 4-323 is limited in the connecting sleeve 4-321 by the limiting pin 4-324. Thus, the feeding rack 4-2 is driven by the feeding rack drive device 4-3 to move inward or outward in a direction parallel to the radial direction of the rotating shaft 2-4.

[0054] The clamping frame 4-5 is fixedly mounted on the turntable base plate 2-1. The material handling device 4-6 includes a blowing air pipe 4-61, which has an axially arranged exhaust port 4-611, and the exhaust port 4-611 is arranged radially outward along the blowing air pipe 4-61.

[0055] The material guiding assembly 5 includes two guide rods 5-1, both of which are fixedly mounted on the turntable base 2-2. One guide rod 5-1 is located between the inspection station 1a and the finished product receiving station 1b, with its outer end extending radially outward along the rotation shaft 2-4 to the outside of the clamping frame 4-5 of the corresponding finished product receiving station 1b. The other guide rod 5-1 is located between the finished product receiving station 1b and the defective product receiving station 1c, with its outer end extending radially outward along the rotation shaft 2-4 to the outside of the clamping frame 4-5 of the corresponding defective product receiving station 1c.

[0056] When using the ring opening detection device of the present invention: according to the size of the ring opening of the garment being tested, the distance between the fixed support rod 3-11 and the movable support rod 3-12 of the detection mechanism 3 is set so that the distance between the fixed support rod 3-11 and the movable support rod 3-12 is greater than or equal to the width of the ring opening, ensuring that the ring opening is not easily detached after being fitted onto the fixed support rod 3-11 and the movable support rod 3-12. First, the opening of the first garment to be tested is placed on the fixed support rod 3-11 and the movable support rod 3-12 of the testing mechanism 3 located at testing station 1a. Then, the movable support rod 3-12 moves away from the fixed support rod 3-11 to the set testing position. At this time, the elasticity of the opening is detected by the weighing sensor 3-4 at the fixed support rod 3-11. If the detected value is within the maximum value of the elasticity requirement range, the test is qualified. If it exceeds the maximum value of the elasticity requirement range, it means that the elasticity of the opening is too large and it is not easy to be stretched open, so it is not easy to pass through the head or other positions when wearing it, and the test is judged as unqualified. Then, the mounting bracket 2-3 of the turntable assembly 2 rotates counterclockwise one station, and the worker installs the second product to be tested on the corresponding testing mechanism 3. At this time, the first garment to be tested rotates with the testing mechanism 3 to the finished product receiving station 1b. Under the guidance of the guide rod 5-1, the garment falls onto the outside of the clamping frame 4-5, located between the clamping frame 4-5 and the release frame 4-2. The first garment to be tested has been tested. If it is qualified, the release frame drive device 4-3 drives the release frame 4-2 to move inward, tightening and fixing the first garment to be tested on the clamping frame 4-5. Then, the moving support rod 3-12 moves towards the fixed support rod 3-11 to a position smaller than the width of the opening. The air outlet 4-611 of the blowing air pipe 4-61 blows air outward, causing the first garment to be tested to detach from the moving support rod 3-12 and the fixed support rod 3-11, flip over the upper part of the release frame 4-2, and then rest on the release frame 4-2. Then, the release frame drive device 4-3 drives the release frame 4-2 to move outward, completing the receiving of the finished product. If the first garment to be tested fails the inspection, the receiving mechanism 4 at the finished product receiving station 1b will not operate. The garment will then be received by the receiving mechanism 4 at the defective product receiving station 1c when it rotates to the latter. Workers only need to place the garment on the testing device at the inspection station 1a, and the subsequent receiving by the corresponding receiving mechanism greatly improves inspection efficiency, reliability, and consistency.
