Description

Technical Field

[0001] The utility model relates to the technical field of glove ironing and forming, in particular to a device for ironing and spreading four fingers of gloves. Background Art

[0002] Knitted gloves are made from pure or blended yarns of various textile fibers, knitted on a glove machine. They undergo sewing processes such as lining, cuffing, and sewing fingertips and forks. They are then brushed or felted, and ironed to set the gloves. Their design and structure primarily consist of a hemmed cuff, the back of the hand, the palm, an eccentric thumb, pinky, ring, middle, and index fingers. These three parts are collectively referred to as the "four fingers." In the past, ironing and shaping gloves were typically done manually. This was a time-consuming and labor-intensive process, with the gloves being placed and removed entirely by hand. This resulted in high labor intensity, low ironing efficiency, and inconsistent quality after ironing, with a high rework rate. To address this, our company recently developed a glove ironing production line.

[0003] According to the glove ironing and shaping process regulations, after the thumb portion of the glove is stretched and shaped, the four fingers of the glove must be combed and flattened, and the back of the hand must be ironed and shaped. Therefore, the design of a glove ironing production line requires the use of four-finger ironing and combing equipment to comb and flatten the pinky, ring, middle, and index fingers, and to iron and shape the back of the hand, ultimately ensuring that the finished gloves meet factory acceptance standards. However, no technical documentation related to four-finger ironing and combing equipment has been found in the prior art. Therefore, a solution to this problem is urgently needed. Utility Model Content

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and, after years of research and development experience in this industry, continuously experimented and modified, which ultimately led to the development of the four-finger glove ironing and combing device.

[0005] To address the aforementioned technical issues, the present invention relates to a four-finger glove ironing and flattening device, comprising a six-degree-of-freedom robotic arm, a hanging ironing device, and a four-finger flattening tool. The six-degree-of-freedom robotic arm is used to carry the hanging ironing device and is positioned adjacent to a circular glove ironing conveyor line. The four-finger flattening tool is integrally assembled with the hanging ironing device. After the gloves are delivered to the four-finger ironing and flattening station, the circular glove ironing conveyor line pauses. During this time, the hanging ironing device irons the back of the glove while the four-finger flattening tool alternately flattens the four fingers of the glove.

[0006] As a further improvement of the technical solution disclosed by the present utility model, the ironing device includes a hanging iron and an ironing piece. The cross-section of the ironing piece is in a "U" shape, which is sequentially connected by a left-side blocking section, a middle flattening section, and a right-side blocking section. The middle flattening section is in contact with and fixed to the ironing surface of the hanging iron. A plurality of steam circulation holes are evenly distributed on the middle flattening section. During the ironing process, the water inside the hanging iron generates hot steam due to heat, and reaches the back of the glove through the steam circulation holes, softening the fabric fiber structure. At the same time, the middle flattening section continuously presses and smooths the back of the glove, and during this process, the left-side blocking section and the right-side blocking section cooperate to regularize the side edges of the back of the glove.

[0007] As a further improvement of the technical solution disclosed by the present utility model, the ironing piece is detachably fixed to the hanging iron by means of countersunk screws. At least one countersunk screw threaded hole for the countersunk screw to be screwed into is formed on the hanging iron. Correspondingly, at least one countersunk screw mounting hole for the countersunk screw to pass through is formed on the middle flattening section.

[0008] As a further improvement of the technical solution disclosed by the present utility model, a limiting step body is formed by continuously extending backward from the rear side wall of the middle flattening section. The ironing surface of the hanging iron is recessed to form a limiting sunk groove with a contour shape consistent with that of the limiting step body.

[0009] As a further improvement of the technical solution disclosed in the present invention, the four-finger combing and unfolding tooling includes a connecting transition piece, a left-mounted stretching plug-in plate, a middle-mounted stretching plug-in plate, a right-mounted stretching plug-in plate, a left-mounted compression spring, a middle-mounted compression spring, a right-mounted compression spring and a pin. The connecting transition piece is detachable to achieve assembly with the ironing piece. Near its top area, the rear side wall of the connecting transition piece continues to extend backward to form a mounting boss. Along its width direction, a left-mounted mounting slot for installing the left-mounted stretching plug-in, a middle-mounted mounting slot for installing the middle-mounted stretching plug-in and a right-mounted mounting slot for installing the right-mounted stretching plug-in are sequentially opened on the mounting boss. In addition, a horizontal mounting hole for installing the pin is opened on the mounting boss, which is connected with the left-mounted mounting slot, the middle-mounted mounting slot and the right-mounted mounting slot. The left, center, and right compression springs all use the connecting transition piece as their installation foundation and are used to pull the tail ends of the left, center, and right extension plates in a corresponding manner. After the left, center, and right extension plates are initially installed and positioned relative to the left, center, and right mounting slots, the pins are inserted into the transverse mounting holes, allowing the left, center, and right extension plates to be articulatedly assembled with the mounting bosses. During the combing and flattening operation on the four fingers of the glove, the left, center, and right extension plates adaptively perform a yaw motion due to the reaction force applied, depending on the specific conditions of the four fingers being ironed. This causes the stored compression of the left, center, and right compression springs to change synchronously.

[0010] As a further improvement to the technical solution disclosed in the present invention, the connecting transition piece is fixedly connected to the ironing element by means of a plurality of screws. The connecting transition piece is provided with screw mounting holes for the screws to pass freely through, and correspondingly, the central flattening section is provided with screw threaded holes for the screws to be screwed into.

[0011] As a further improvement of the technical solution disclosed in the present utility model, a weight-reducing notch is provided in the connecting transition piece.

[0012] In practical applications, the four-finger glove ironing and combing device disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:

[0013] 1) The four-finger glove ironing and flattening machine utilizes a six-degree-of-freedom robotic arm with exceptional flexibility and precision. Through optimization, it seamlessly integrates with the ironing device and four-finger flattening tooling. This allows the machine to simultaneously iron the back of the glove and flatten the four fingers, without requiring human intervention.

[0014] 2) Guided by the six-degree-of-freedom robotic arm, the ironing device and the four-finger combing and unfolding tooling work alternately, combing and flattening the four fingers of the glove while ironing and shaping the back of the hand, ultimately ensuring that the finished gloves meet factory acceptance standards.

[0015] 3) The four-finger glove ironing and combing device has a very simple design structure, is easy to manufacture and implement, and has a low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In the description of the present invention, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] The following is a further detailed description of the present invention in conjunction with specific embodiments. Figure 1 As shown in the figure, the four-finger glove ironing and combing equipment is used in conjunction with the four-finger hand mold accompanying fixture, and the gloves are flattened through "pulling", "pressing" and "spraying" actions.

[0029] Figure 2 The figure shows a three-dimensional schematic diagram of the four-finger ironing and combing device for gloves disclosed in the present invention. It can be seen that it is mainly composed of several parts, such as a six-degree-of-freedom robot arm 1, a hanging ironing device 2, and a four-finger combing and flattening tool 3. Among them, the six-degree-of-freedom robot arm 1 is arranged near the circular glove ironing conveyor line and is located on a shelf. The hanging ironing device 2 is fixed to the execution end of the six-degree-of-freedom robot arm 1. The four-finger combing and flattening tool 3 is assembled into one with the hanging ironing device 2. After the gloves are conveyed to the four-finger ironing and flattening station, the circular glove ironing conveyor line suspends the conveying action. During this period, the hanging ironing device 2 performs the ironing operation on the back of the glove, and alternately, the four-finger combing and flattening tool 3 performs the combing and flattening operation on the four fingers of the glove.

[0030] In this embodiment, the four-finger ironing and combing equipment for gloves uses a six-degree-of-freedom robotic arm 1 with extremely excellent flexibility and movement accuracy. More importantly, the ironing device 2 and the four-finger combing and flattening tooling 3 are integrated with the six-degree-of-freedom robotic arm 1, so that the four-finger ironing and combing equipment for gloves can have both the function of ironing the back of the glove and the function of combing and flattening the four fingers of the glove, and no human intervention is required throughout the process.

[0031] As shown in Figure 3 and 4 , the hanging ironing device 2 is mainly composed of a hanging iron 21 and an ironing member 22. As shown in Figure 5 , the cross-section of the ironing member 22 is in a "U" shape, which is sequentially connected by a left-side blocking section 221, a middle pressing section 222, and a right-side blocking section 223. The middle pressing section 222 is in contact with and fixed to the ironing surface of the hanging iron 21. A plurality of steam circulation holes 2222 are evenly distributed on the middle pressing section 222. During the ironing process, the water inside the hanging iron 21 generates hot steam due to heat, and reaches the back of the glove through the steam circulation holes 2222, softening the fabric fiber structure of the glove. At the same time, the middle pressing section 222 continuously presses and smooths the back of the glove. During this process, the left-side blocking section 221 and the right-side blocking section 223 cooperate to regularize the side edges of the back of the glove. In practical applications, under the action guidance of the six-axis robotic arm 1, the hanging ironing device 2 and the four-finger combing tooling 3 alternately function. During this period, both the hanging ironing device 2 and the four-finger combing tooling 3 need to act repeatedly for multiple times until the four fingers of the glove are combed and flattened, and the back of the glove is ironed and shaped, ultimately ensuring that the finished glove meets the factory acceptance standards.

[0032] It is known that in practical applications, it is very common that the ironing member 22 is accidentally damaged or the specifications of the gloves to be processed change, that is, it is required to frequently perform replacement operations on the ironing member 22, and the entire operation process is time-consuming and laborious. In view of this, as a further optimization of the above technical solution, as shown in Figure 3 and 4 , the ironing member 22 is detachably fixed to the hanging iron 21 by means of countersunk screws. At least one countersunk screw thread hole for the countersunk screw to be screwed into is formed on the hanging iron 21. Correspondingly, at least one countersunk screw mounting hole 2223 for the countersunk screw to pass through is formed on the middle pressing section 222.

[0033] As shown in Figure 6 , a limiting step body 2221 is formed by continuously extending backward from the rear side wall of the middle pressing section 222. The ironing surface of the hanging iron 21 is recessed to form a limiting sunk groove (not shown in the figure) with a contour shape consistent with that of the limiting step body 2221. Thus, when assembling or replacing the ironing member 22, it is beneficial to achieve precise alignment between the ironing member 22 and the hanging iron 21, and the alignment process is extremely fast.

[0034] As shown in Figure 3 and 4As shown in FIG, it can be clearly seen that the four-finger combing tool 3 is mainly composed of a connecting transition piece 31, a left-positioned stretching plate 32, a middle-positioned stretching plate 33, a right-positioned stretching plate 34, a left-positioned compression spring 35, a middle-positioned compression spring 36, a right-positioned compression spring 37, and a pin 38. Among them, the connecting transition piece 31 is detachable to achieve assembly with the ironing piece 22. Figure 7 、 8 As shown in Figures 9 and 10, near the top region, the rear sidewall of the connecting transition piece 31 continues to extend rearward to form a mounting boss 311. Along its width, the mounting boss 311 is provided with a left mounting slot 3111, a center mounting slot 3112, and a right mounting slot 3113, respectively for receiving the left, center, and right extension plates 32, 33, and 34, respectively. Furthermore, the mounting boss 311 is provided with a transverse mounting hole 3114 for receiving a pin 38, which intersects the left, center, and right mounting slots 3111, 3112, and 3113. The left, center, and right compression springs 35, 36, and 37 are all mounted on the connecting transition piece 31 and are used to pull the tail ends of the left, center, and right extension plates 32, 33, and 34, respectively. After the left-placed stretching plate 32, the middle-placed stretching plate 33, and the right-placed stretching plate 34 have completed the preliminary installation and positioning relative to the mounting boss 311, the pin 38 is inserted into the transverse mounting hole 3114, and the left-placed stretching plate 32, the middle-placed stretching plate 33, and the right-placed stretching plate 34 are able to be hingedly assembled with the mounting boss 311. During the combing and flattening operation on the four fingers of the glove, according to the specific situation of the four fingers to be ironed, the left stretching plate 32, the middle stretching plate 33, and the right stretching plate 34 adaptively perform a yaw motion due to the reaction force, and accordingly, the stored compression amounts of the corresponding left compression spring 35, the middle compression spring 36, and the right compression spring 37 change synchronously, so that the pressing force applied to the gap area between the four fingers of the glove is always maintained within a reasonable value range, which can effectively avoid the phenomenon of substandard combing and flattening effect of the four fingers due to insufficient pressing force and the occurrence of compression damage to the four fingers due to excessive pressing force.

[0035] As is known to common sense, the connecting transition piece 31 can adopt various design structures to achieve a fixed connection with the ironing piece 22. However, here we recommend an implementation scheme that is simple in design structure, highly stable in connection, easy to implement, and time-saving and labor-saving in assembly and disassembly process, specifically: Figure 3 、 4 As shown in FIG, the connecting transition piece 31 is fixedly connected to the ironing piece 22 by means of a plurality of screws. Figure 5 、 7As shown in FIG, a screw installation hole 312 for the screw to pass freely is provided on the connecting transition piece 31, and correspondingly, a screw threaded hole 2224 for the screw to be screwed into is provided on the middle flattening section 222.

[0036] Depend on Figure 7 、 8 As shown in FIG, it can be clearly seen that the connecting transition piece 31 is also formed with a weight-reducing notch 313. This effectively reduces the weight of the connecting transition piece 31, thereby reducing the workload and energy consumption of the six-degree-of-freedom robotic arm 1, while ensuring that the structural strength of the connecting transition piece 31 meets the application requirements. It also helps to avoid the hanging iron 21.

[0037] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
