Technical Field

[0001] This utility model relates to the field of disposable underwear production technology, and in particular to a disposable underwear turning mechanism. Background Technology

[0002] Disposable underwear is a type of underwear used only once, typically made from cellulose materials (such as cotton, bamboo fiber, or wood pulp fiber), designed to provide a comfortable and hygienic wearing experience. Disposable underwear is commonly used for travel, business trips, medical care, postpartum recovery, and other occasions. Disposable underwear production equipment involves processing raw materials through a series of steps to produce finished underwear. This typically includes fabric cutting, sewing, adding waistbands, labeling, inspection, and packaging. Each step requires different equipment and operators. The scale and configuration of underwear production lines vary depending on the manufacturer and product. Some large underwear companies have complete underwear production lines, completing everything from raw materials to finished products in their own factories; while smaller companies may only have partial production lines or outsource underwear production. Regardless of size, the goal of an underwear production line is to efficiently and consistently produce underwear products that meet quality standards and customer needs.

[0003] After being sewn, disposable underwear needs to be turned inside out to facilitate subsequent packaging and other processes. In existing technologies, this turning process is done manually, which is inefficient; moreover, in mass production, manual labor is arduous and costly. Therefore, how to efficiently turn disposable underwear inside out is a problem that those skilled in the art need to consider. Utility Model Content

[0033] The present invention will be further described in detail below with reference to specific embodiments:

[0034] like Figures 1-6 As shown, this utility model is applied to the manufacturing of disposable underwear, specifically the process of turning the underwear inside out after sewing. After sewing, the first and second picking devices respectively pick up the upper and lower ends of the abdominal panel and open it up; the flipping plate abuts against the wave bottom, allowing the wave bottom to pass through the abdominal panel, completing the flipping of the wave bottom; then the stop block presses against the abdominal panel, causing the abdominal panel to turn inside out. After the entire flipping of the underwear is completed, the gripper device finally picks it up and releases it from the flipping plate, placing it on the carrier plate to complete the unloading process.

[0035] In this embodiment, for ease of explanation, as shown in the figure, the movement direction of the flap is taken as the first direction S1, and the movement direction of the two blocks is taken as the second direction S2, and the first direction S1 and the second direction S2 are perpendicular to each other.

[0036] Specifically:

[0037] A disposable underwear turning mechanism includes a frame and a machine base 1. An opening assembly 2, a turning assembly 3, and a feeding assembly 4 are all mounted on the frame.

[0038] The opening assembly 2 includes a first picking device 21 and a second picking device 22 respectively disposed at the upper and lower ends of the machine base 1. The first picking device 21 and the second picking device 22 can pick up the upper and lower ends of the underwear respectively and move upward and downward respectively.

[0039] The first pickup device 21 includes a first bracket 211 and a first suction cup assembly 212 connected to the first bracket 211; the upper end of the first bracket 211 is connected to a first driving device 213 that drives it to move in the vertical direction. The second pickup device 22 includes a second suction cup assembly 221 and a second driving device 222 connected to the second suction cup assembly 221 and capable of driving it to move in the vertical direction.

[0040] In this embodiment, the suction cups on the first suction cup assembly 212 and the second suction cup assembly 221 are both needle-punched suction cups, each with multiple suction cups arranged in a straight line, allowing the first suction cup assembly 212 and the second suction cup assembly 221 to respectively suck up the abdominal panel of the underwear from above and below. After suction, driven by the first driving device 213 and the second driving device 222 respectively, they move upward and downward, causing the abdominal panel of the underwear to open up.

[0041] To facilitate seamless connection with the preceding sewing process, a linear module 23 can be connected to the upper end of the first drive device 213. Simultaneously, a third suction cup assembly 214 is connected to the first bracket 211. This third suction cup assembly 214 also features multiple needle-punched suction cups and is designed to mimic the shape of underwear. For example... Figure 5 As shown, after the underwear is sewn, the first suction cup assembly 212 picks up the abdominal panel of the underwear, and the third suction cup assembly 214 picks up the other parts of the underwear. Then, it is transferred to the machine 1 at the flipping plate by the straight module 23 for easy flipping operation. No manual intervention is required for the transfer.

[0042] The flipping assembly 3 includes a flip plate 31 and a flipping edge assembly 32. The flipping edge assembly 32 includes two symmetrically arranged blocks 321. The flip plate 31 is arranged vertically between the first picking device 21 and the second picking device 22, and horizontally between the two blocks 321. It can move along the first direction S1 and pass between the two blocks 321.

[0043] The flap 31 is located at the upper end of the machine base 1. The flap 31 is connected to a third drive device (not shown in the figure). The third drive device can be located at the lower end of the machine base 1 and can drive the flap 31 to move in the first direction S1.

[0044] The flange assembly 32 includes a third bracket 322, on which a fourth driving device 323 is connected. A stop block 321 is connected to the fourth driving device 323, and the fourth driving device 323 drives both stop blocks 321 to move simultaneously in opposite directions along a second direction S2. Each of the two stop blocks 321 has a limiting groove 3211 on its side where they approach each other, with the length direction of the limiting groove 3211 being the first direction S1. When the two stop blocks 321 approach each other, the two limiting grooves 3211 can connect to the flap 31.

[0045] The third bracket 322 is connected to a fixed plate 324 via a slide rail 326 with a sliding direction of the first direction S1; a fifth drive device 325 is connected to the fixed plate 324, the third bracket 322 is connected to the fifth drive device 325, and can move on the slide rail 326 under the drive of the fifth drive device 325.

[0046] In this embodiment, after the abdominal panel of the underwear is opened, the wave bottom of the underwear is located at the end of the flap 31. The third driving device drives the flap 31 to move along the first direction S1 and abut against the wave bottom until the wave bottom passes through the abdominal panel (e.g., Figure 6 (As shown) After that, the first pickup device 21 and the second pickup device 22 reset; the two stops 321 move towards each other under the drive of the fourth drive device 323 until they are engaged in the limiting groove 3211 on both sides of the flip plate 31; then the fifth drive device 325 drives the stops 321 to move along the first direction S1 towards the side closer to the underwear through the third bracket 322. At the same time, the stops 321 abut against the belly panel, so that the belly panel is flipped over. Then the stops 321 move away from the flip plate 31 and reset. At this time, the underwear is completely flipped over and fitted onto the flip plate 31.

[0047] The unloading assembly 4 includes a gripper device 41 and a carrier plate 42 disposed below the gripper device 41. A lifting device 421 is connected to the lower end of the carrier plate 42. The gripper device 41 is connected to the fixed plate 324 through a sixth driving device 411, and the gripper device 41 moves along the first direction S1 under the drive of the sixth driving device 411.

[0048] In this embodiment, the gripper device 41 grips the bottom edge of the underwear on the flip plate 31 and moves along the first direction S1 under the drive of the sixth drive device 411, causing the underwear to detach from the flip plate 31 and be dragged onto the carrier plate 42. The lifting device 421 drives the carrier plate 42 to move the underwear downwards, and the underwear is removed manually or by other equipment, completing the unloading process.

[0049] The process of turning the disposable underwear inside out in this embodiment is as follows:

[0050] After the disposable underwear is sewn, it is picked up by the first suction cup assembly 212 and the third suction cup assembly 214, and transferred to the machine platform 1 under the drive of the linear module 23, and is located at the end of the flip plate 31. At this time, the first suction cup assembly 212 picks up the upper abdominal piece of the underwear and is positioned directly above the second suction cup assembly 221; the second suction cup assembly 221 picks up the lower abdominal piece; and the third suction cup assembly 214 disengages.

[0051] Driven by the third drive device, the flip-up plate 31 moves along the first direction S1 and pushes against the bottom of the underwear, passing between the first suction cup assembly 212 and the second suction cup assembly 221; the first suction cup assembly 212 and the second suction cup assembly 221 detach from the underwear and return to their original positions. At this time, the underwear is fitted onto the flip-up plate 31 and most of the area has been flipped over, while the belly panel has not been flipped over. The flip-up plate 31 moves between the two stops 321, and the belly panel does not extend beyond the stops 321.

[0052] The fourth drive device 323 drives the two stops 321 to move simultaneously towards each other in the second direction S2 until they are engaged in the limiting groove 3211 on both sides of the baffle. The fifth drive device 325 drives the stops 321 to move along the first direction S1 through the third bracket 322, and to move closer to the abdominal piece, abutting against the abdominal piece and causing the abdominal piece to flip over. At this time, the entire flipping of the underwear is completed, and the underwear is placed on the flip plate 31.

[0053] The gripper device 41 grips the bottom of the underwear and moves along the first direction S1 under the drive of the sixth drive device 411, dragging the underwear away from the flip plate 31. After the underwear falls onto the carrier plate 42, the gripper is released, completing the side unloading of the underwear. The lifting device 421 drives the carrier plate 42 to transfer the underwear downwards, and finally the underwear is removed manually or by other equipment.

[0054] It should be noted that during the above process, when the stop blocks 321 move towards each other, they should not be too tightly pressed against the flap 31; they should only make slight contact with the flap 31 or have a slight gap. When the gripper device 41 grips the bottom of the wave, the clamping force should not be too large, otherwise the underwear will be pressed against the flap 31 and unable to detach from it.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
