Description

Technical Field

[0001] This invention relates to the field of processing equipment for the back section of underwear, and in particular to a high-efficiency processing machine for the back section of underwear. Background Technology

[0002] Currently, according to relevant textile standards, underwear should be labeled with information such as fiber composition and size to better display its composition and specifications. Traditionally, this involved sewing a label strip onto the inside of the underwear, but this could cause discomfort for the user. Therefore, most underwear labels are now printed using ink transfer printing.

[0003] To avoid the markings affecting the patterns on the outside of the underwear, the markings are currently printed on the inside of the underwear. Therefore, in current ink pad printing operations for underwear markings, the underwear must be manually held and the area to be marked placed on the pad of the printing machine, resulting in low overall processing efficiency. Furthermore, the applicant has designed an automatic underwear shaping and stacking machine disclosed in ZL201910105749.5, which can efficiently complete the shaping and stacking of underwear. However, how to automate the underwear marking process and integrate it with this machine, enabling a single person to efficiently complete the marking, shaping, and stacking operations, is a problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency processing machine for the post-processing of underwear. This invention not only improves processing efficiency but also has the advantage of requiring less manpower.

[0005] The technical solution of this invention: A high-efficiency underwear post-processing machine includes a rotating panty-covering mechanism. A panty-covering station, an oven, and a panty-taking and stacking mechanism are arranged in a ring around the outer side of the rotating panty-covering mechanism. A pad printing station is arranged between the panty-covering station and the oven. At least four evenly distributed panty-covering plates are connected to the rotating panty-covering mechanism, and each panty-covering plate has a pad printing notch corresponding to the marked pad printing area. The rotating panty-covering mechanism can drive the panty-covering plates to circulate sequentially between the panty-covering station, the pad printing station, the oven, and the panty-taking and stacking mechanism. The pad printing station includes a pad printing frame. Both sides of the top are provided with clamping parts for clamping the side parts of the trouser board; a pad printing machine and a lifting block are connected at the position between the two clamping parts on the top of the pad printing machine frame, and a vertical lifting cylinder is connected between the lifting block and the pad printing machine frame; a sliding rod parallel to the direction of putting on the trousers on the trouser board is slidably connected to the lifting block, and a toggle telescopic cylinder is connected between the sliding rod and the lifting block; a crossbar is connected to one end of the sliding rod, and multiple downward protruding toggle blocks are connected to the crossbar; a sliding groove is provided at the position of each toggle block on the trouser board, and the sliding groove is parallel to the sliding rod.

[0006] In the aforementioned high-efficiency underwear back-end processing machine, the clamping part includes a downward telescopic cylinder and a lifting telescopic cylinder fixed on the pad printing machine frame. The downward telescopic cylinder and the lifting telescopic cylinder are located on the upper and lower sides of the pant cover plate, respectively. The bottom end of the telescopic rod of the downward telescopic cylinder and the top end of the telescopic rod of the lifting telescopic cylinder are both connected to a fixed clamping plate.

[0007] In the aforementioned high-efficiency underwear post-processing machine, a tray is connected to the pad printing frame at the position directly below the pad printing notch, and a guide plate with an inclined top is connected to the side of the pad printing frame facing the pant work station.

[0008] In the aforementioned high-efficiency underwear back-end processing machine, a sensor is connected to the pad printing frame, and multiple sensor lights are arranged in a row and parallel to the sliding rod directly below the sensor. The sensor and the sensor lights are located on the upper and lower sides of the pant cover plate, respectively. A sensing notch is provided on the pant cover plate at the position corresponding to the position between the sensor and the multiple sensor lights.

[0009] In the aforementioned high-efficiency underwear post-processing machine, the pad printing machine includes an ink cartridge fixed on the pad printing machine frame, the ink cartridge being located above the pant cover plate; a pad printing head is provided above the ink cartridge, a servo lifting unit is connected to the pad printing head, and a horizontal servo moving unit is connected to the servo lifting unit and the pad printing machine frame, the moving direction of the horizontal servo moving unit being the same as the sliding direction of the sliding rod.

[0010] In the aforementioned high-efficiency underwear post-processing machine, both the servo lifting unit and the horizontal servo moving unit are servo linear modules.

[0011] In the aforementioned high-efficiency underwear post-processing machine, a cover is provided above the ink cartridge, and a horizontal telescopic cylinder is connected between the cover and the pad printing frame.

[0012] In the aforementioned high-efficiency underwear back-end processing machine, there are two actuating blocks, which are located at the two ends of the crossbar respectively.

[0013] In the aforementioned high-efficiency underwear post-processing machine, a fixed base is provided at the bottom of the pad printing frame, the pad printing frame is slidably connected to the fixed base, and a lead screw slider adjustment mechanism is connected between the pad printing frame and the fixed base.

[0014] Compared with existing technologies, this invention incorporates a pad printing station between the panty-covering station and the drying oven in a traditional automatic panty-setting and stacking machine. Only one person needs to place the panties onto the panty-covering plate, and rotating the panty-covering mechanism causes the panties on the plate to sequentially pass through the pad printing station, the drying oven, and the panty-retrieving and stacking mechanism, thus efficiently completing the marking, shaping, and panty-retrieving / stacking operations in one go. The pad printing station uses two clamping parts to hold the panty-covering plate on both sides, fixing the panties in place. This is further enhanced by a lifting cylinder and lifting blocks. The system involves moving a telescopic cylinder, a sliding rod, a crossbar, and multiple downward-protruding actuating blocks on the crossbar to pull down only the underwear located above the panty board without pulling down the entire pair of underwear. The pad printing machine then uses the printing notch on the panty board to mark and print the inside of the underwear. Each actuating block on the panty board has a groove; the actuating block slides along the groove after being inserted, allowing for a more stable removal of the underwear located above the panty board. This prevents the underwear from springing back during the printing process and ensures high equipment stability.

[0015] Furthermore, in this invention, when the clamping part is in the released state, there is a certain distance between the fixed clamping plates on the downward telescopic cylinder and the upward telescopic cylinder and the pant cover plate. This ensures that when the pant cover plate is rotated by the pant cover mechanism to change positions, the pant cover plate is less likely to collide with the fixed clamping plates on the upper and lower sides, resulting in higher equipment stability. When the clamping part is clamping, the clamping area of ​​the two fixed clamping plates is large, which can better clamp the underwear on the pant cover plate. At the same time, a support plate is provided directly below the pad printing notch of the pant cover plate, so that when the pad printing machine performs marking pad printing, the support plate can lift the underwear below the pant cover plate, thereby better performing the marking pad printing operation. The top of the guide plate on one side of the support plate is inclined, which can guide the support plate to the top of the support plate.

[0016] The pad printing machine frame is equipped with sensors and multiple rows of sensor lights on the upper and lower sides of the panty cover plate, and there is a sensing notch between the sensors and the rows of sensor lights on the panty cover plate. Through the recognition and cooperation of the sensors and the rows of sensor lights, the position of the panty cover plate can be detected, thereby accurately and uniformly controlling the horizontal servo moving part to drive the pad printing head to perform marking and pad printing operations on the panty cover, and it can be used for various sizes of panty cover.

[0017] The ink cartridge is equipped with a cover that can be opened and closed by a horizontal telescopic cylinder, so that the cover is only opened when the printing head is dipped in ink, which can effectively prevent the ink from curing.

[0018] The bottom of the pad printing machine frame is slidably connected to the fixed base, and a screw-slider adjustment mechanism is connected between the pad printing machine frame and the fixed base, which can adjust the relative position between the two and make it easier to debug and install the pad printing station.

[0019] Therefore, this invention not only improves processing efficiency, but also has the advantages of requiring less manpower, having higher operational stability, better marking and printing effect, and wider applicability. Attached Figure Description

At least four evenly distributed trouser-covering plates 6 are connected to the rotating trouser-covering mechanism 1, and each trouser-covering plate 6 has a pad printing notch 8 corresponding to the marked pad printing area. The rotating trouser-covering mechanism 1 can drive the trouser-covering plates 6 to circulate sequentially between the trouser-covering station 2, the pad printing station 5, the oven 3, and the trouser-collecting and stacking mechanism 4. The pad printing station 5 includes a pad printing frame 7, and both sides of the top of the pad printing frame 7 are provided with clamping points for holding the trouser-covering plates 6. The clamping part at the edge; the top of the pad printing machine frame 7 is connected to the pad printing machine and the lifting block 10 at the position between the two clamping parts, and the lifting block 10 and the pad printing machine frame 7 are connected by a vertical lifting cylinder 11; the lifting block 10 is horizontally slidably connected to a sliding rod 12 parallel to the direction of putting on the pants on the pant cover 6, and the sliding rod 12 and the lifting block 10 are connected by a toggle telescopic cylinder 13. One end of the sliding rod 12 is connected to a crossbar 14, and multiple downward protruding toggle blocks 15 are connected to the crossbar 14; the pant cover 6 is provided with a groove 16 at the position of each toggle block 15, and the groove 16 is parallel to the sliding rod 12.

[0027] The clamping part includes a downward telescopic cylinder 18 and a lifting telescopic cylinder 19 fixed on the pad printing frame 7. The downward telescopic cylinder 18 and the lifting telescopic cylinder 19 are located on the upper and lower sides of the pant cover plate 6, respectively. The bottom end of the telescopic rod of the downward telescopic cylinder 18 and the top end of the telescopic rod of the lifting telescopic cylinder 19 are both connected to a fixed clamping plate 20. A support plate 9 is connected to the pad printing frame 7 at a position directly below the pad printing notch 8. A guide plate 33 with an inclined top is connected to the side of the support plate 9 facing the pant cover station 2. A sensor 21 is connected to the pad printing frame 7. A plurality of sensor lights 22 are arranged in a row and parallel to the sliding rod 12 directly below the sensor 21. The sensor 21 and the sensor lights 22 are located on the upper and lower sides of the pant cover plate 6, respectively. A sensing notch 23 is provided on the pant cover plate 6 at a position between the sensor 21 and the plurality of sensor lights 22. The pad printing machine includes an ink cartridge 24 fixed on the pad printing machine frame 7, located above the trouser plate 6; a pad printing head 25 is arranged above the ink cartridge 24, and a servo lifting part 26 is connected to the pad printing head 25. A horizontal servo moving part 27 is connected to the servo lifting part 26 and the pad printing machine frame 7, and the moving direction of the horizontal servo moving part 27 is the same as the sliding direction of the sliding rod 12; both the servo lifting part 26 and the horizontal servo moving part 27 are servo linear modules; a cover 28 is arranged above the ink cartridge 24, and a horizontal telescopic cylinder 29 is connected between the cover 28 and the pad printing machine frame 7; there are two actuating blocks 15, which are located at the two ends of the crossbar 14 respectively; a fixed seat 31 is arranged at the bottom of the pad printing machine frame 7, and the pad printing machine frame 7 is slidably connected to the fixed seat 31. A lead screw slider adjustment mechanism 32 is connected between the pad printing machine frame 7 and the fixed seat 31.

[0028] Working principle: At the trouser-covering station 2, the worker puts the underwear on the outer end of the horizontal trouser-covering board 6, which can flatten and stretch the underwear.

[0029] Subsequently, the rotating trouser mechanism 1 drives all the trouser plates 6 around it to rotate, transferring the trouser plates 6 at the trouser station 2 to the pad printing station 5. The inclined surface of the top of the guide plate 33 on one side of the tray 9 can guide the trouser plates 6 to the top of the tray 9. Then, the clamping parts on both sides of the pad printing frame 7 fix the trouser plates 6 to both sides (that is, the lifting telescopic cylinder 19 in the clamping part drives the fixed clamping plate 20 connected to it to move upward, and the pressing telescopic cylinder 18 drives the fixed clamping plate 20 connected to it to move downward, performing the clamping operation). Then, the telescopic mechanism is activated. The cylinder 13 extends, causing the sliding rod 12 to slide relative to the lifting block 10, moving the crossbar 14 at the end of the sliding rod 12 to the inner end of the pant cover 6; then, the lifting cylinder 11 drives the lifting block 10 to move down, and simultaneously drives the crossbar 14 and the two downward-protruding actuating blocks 15 at both ends of the crossbar 14 to move down, so that the bottom end of the actuating block 15 extends into the sliding groove 16 of the pant cover 6; then the actuating telescopic cylinder 13 shortens, and the two actuating blocks 15 can slide along the corresponding sliding groove 16, thereby stably pulling down the underwear located above the pant cover 6; then, the pad printing machine marks the underwear. The pad printing operation involves the horizontal telescopic cylinder 29 shortening and retracting the cover 28, thereby opening the top of the ink cartridge 24; the servo lifting unit 26 moving the pad printing head 25 downwards to dip into the ink cartridge 24 and then lifting it up; subsequently, the horizontal telescopic cylinder 29 resetting the cover 28 to close the top of the ink cartridge 24; based on the sensor 21 sensing the situation where the sensor light 22 is covered by underwear through the sensing notch 23, the depth of the underwear on the pant cover 6 is calculated, and the horizontal servo moving unit 27 is controlled to move the servo lifting unit 26 and the pad printing head 25 synchronously. The label is moved to the label transfer position and reset after the label transfer operation is completed; finally, the servo lifting unit 26 drives the transfer head 25 to move down and pass through the transfer notch 8 on the pant cover 6 to perform the label transfer operation on the inside of the underwear. Since the support plate 9 directly below the transfer notch 8 can lift the underwear, the label transfer operation can be completed better; after the transfer operation is completed, the lifting cylinder 11 drives the lifting block 10 to rise and reset, and the toggle block 15 also rises synchronously. The underwear that was pulled down is reset again under the action of the elastic band at its waistband; then, the clamping parts on both sides also release the pant cover 6 again.

[0030] The rotating trouser mechanism 1 continues to rotate, moving the trouser plate 6 of the pad printing station 5 into the oven 3 for shaping; after shaping, the rotating trouser mechanism 1 continues to rotate, moving the trouser plate 6 at the oven 3 to the trouser picking and stacking mechanism to complete the automatic trouser picking and stacking operation; after trouser picking is completed, the rotating trouser mechanism 1 continues to rotate, moving the trouser plate 6 at the trouser picking and stacking mechanism 4 back to the trouser picking station 2.

[0031] If sensor 21 can detect all the sensor lights 22 through the sensing notch 23, it can determine that no underwear is on the pant cover plate 6, and can control the pad printing station not to perform the marking pad printing operation to avoid empty operation, which would cause ink to stick on the fixed clamp plate 20 and stain the subsequent underwear.
