Description

Technical Field

[0001] The invention relates to the technical field of glove ironing and shaping, in particular to a glove ironing and shaping production line. Background Art

[0002] Knitted gloves are made of pure or blended yarns of various textile fibers, knitted on a glove machine, and sewn through sewing processes such as clamping lining, cuffs, sewing fingertips and forks, etc., and then through brushing or shrinking, ironing and shaping. In terms of its design structure, it is mainly composed of the hemming cuff, the back of the hand, the palm, the eccentric thumb, the little finger, the ring finger, the middle finger and the index finger. The little finger, the ring finger, the middle finger and the index finger are collectively referred to as the four fingers. In the past few years, the ironing and shaping of gloves were usually completed manually, which was time-consuming and labor-intensive. The picking and placing actions were completely completed manually, the labor intensity of the workers was high, the ironing efficiency was very low, and the quality after ironing and shaping was uneven, and the rework rate was high. For this reason, our company has recently developed a set of glove ironing production lines. Summary of the invention

[0003] Therefore, in view of the above existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience in this industry, which ultimately led to the emergence of the glove ironing and shaping production line.

[0004] In order to solve the above technical problems, the present invention relates to a glove ironing and shaping production line, which consists of a glove big finger flattening and shaping unit, a glove ironing semi-finished product unloading device, a glove ironing semi-finished product conveying platform, a glove four-finger ironing and flattening unit, a glove ironing finished product unloading device and a glove ironing finished product conveying platform.

[0005] The glove ironing and shaping production line follows the following steps to implement the glove ironing operation:

[0006] S1. The gloves are manually supplied to the glove large finger flattening and shaping unit, and the large finger flattening and shaping operation is performed on the gloves to form the glove ironing semi-finished products;

[0007] S2, using the glove ironing semi-finished product unloading equipment to transfer the glove ironing semi-finished product from the glove big finger flattening and shaping unit to the glove ironing semi-finished product conveying platform;

[0008] S3, manually transferring the semi-finished gloves from the semi-finished gloves conveying platform to the four-finger glove ironing and flattening unit, so as to perform four-finger ironing and stretching operations and back ironing and stretching operations on the semi-finished gloves, so as to form finished gloves;

[0009] S4. With the help of the glove ironing finished product unloading equipment, the glove ironing finished product is transferred from the glove four-finger ironing and flattening unit to the glove ironing finished product conveying platform, and then continues to flow to the packaging process.

[0010] As a further improvement of the technical solution disclosed in the present invention, the glove big finger flattening and shaping unit includes an upstream multi-station circular conveyor, a big finger hand model accompanying jig and a glove big finger stretching device. The big finger hand model accompanying jig changes its position due to the driving force from the upstream multi-station circular conveyor, and assists the glove big finger stretching device to flatten the glove big finger through "pulling" and "pressing" actions.

[0011] As a further improvement of the technical solution disclosed in the present invention, the thumb hand model accompanying fixture includes an upstream base, a thumb profiling arm and a thumb electric heating unit. The upstream base is directly carried by the upstream multi-station circular conveyor. The thumb profiling arm is assembled with the upstream base in an insertion manner, and after the assembly is completed, it maintains an upright posture. The thumb electric heating unit is used to supply heat to the thumb profiling arm, so that the thumb profiling arm can be heated.

[0012] As a further improvement of the technical solution disclosed in the present invention, the glove thumb stretching device includes an upstream six-degree-of-freedom robot arm and a thumb stretching tool. The upstream six-degree-of-freedom robot arm is used to load the thumb stretching tool, and is arranged adjacent to the upstream multi-station circular conveyor. When the glove is assembled with the accompanying jig relative to the thumb hand model and at a certain moment in the process of circular circulation, the upstream multi-station circular conveyor briefly stops, and during this period, the thumb stretching tool is used to perform stretching and shaping operations on the glove thumb.

[0013] As a further improvement of the technical solution disclosed in the present invention, the thumb stretching tooling includes a parallel finger cylinder, a left stretching assembly and a right stretching assembly. The parallel finger cylinder is installed at the execution end of the upstream six-degree-of-freedom robot arm, and its left and right fingers are respectively assembled into one with the left stretching assembly and the right stretching assembly in a one-to-one and detachable manner. The left stretching assembly and the right stretching assembly are respectively formed with a left thumb stretching profiling notch and a right thumb stretching profiling notch. Before the ironing and stretching operation is formally performed on the thumb of the glove, the left stretching assembly and the right stretching assembly are brought together, and the left thumb stretching profiling notch and the right thumb stretching profiling notch are merged into a thumb stretching profiling notch. When the thumb hand model accompanying jig flows to the thumb stretching station, the upstream six-degree-of-freedom robot arm moves to change the posture until the parallel finger cylinder is adjusted to a flat state, and then the upstream six-degree-of-freedom robot arm continues to move to drive the parallel finger cylinder to perform a downward displacement movement, so that the thumb of the glove can gradually penetrate into the thumb stretching contouring gap, and in this process, the thumb of the glove is softened due to the high temperature. At the same time, it is pulled and flattened due to the synergistic effect of the left-placed stretching assembly and the right-placed stretching assembly.

[0014] As a further improvement of the technical solution disclosed in the present invention, the glove four-finger ironing and flattening unit includes a downstream multi-station circular conveyor, a four-finger hand mold accompanying jig, and a four-finger ironing and combing device. The four-finger hand mold accompanying jig changes its position due to the driving force from the downstream multi-station circular conveyor, and assists the four-finger ironing and combing device to flatten the gloves through "pulling", "pressing" and "spraying" actions.

[0015] As a further improvement of the technical solution disclosed in the present invention, the four-finger hand model accompanying fixture includes a downstream base, a four-finger profiling arm, a guide slider, a glove hemming cuff clamping assembly and a lower guide bearing. The downstream base is directly carried by the downstream multi-station circular conveyor. The four-finger profiling arm is assembled with the downstream base in an insertion manner, and after assembly, it maintains an upright posture. The guide slider is fixed to the four-finger profiling arm in a detachable manner and is located at the front side of the four-finger profiling arm. The glove hemming cuff clamping assembly is assembled in a sliding connection with the four-finger profiling arm by means of the guide slider. The lower guide bearing is used to transmit a drag force to the glove hemming cuff clamping assembly, and it uses the glove hemming cuff clamping assembly as an installation base. When the semi-finished glove ironing product is completely assembled relative to the four-finger contoured arm, and after the glove hemming cuff clamping assembly is actuated to clamp the back of the hand of the glove, the lower guide bearing lowers its relative height position due to the intervention of external force, and under the guidance of the guide slider, the glove hemming cuff clamping assembly performs a directional downward movement. During this process, the four fingers and the back of the hand of the glove are stretched and flattened due to the dragging force.

[0016] As a further improvement of the technical solution disclosed in the present invention, the glove hemming cuff clamping assembly includes a rear clamping member, a front clamping member, a connecting transition block, a pin shaft and an upper guide bearing. Along its length direction, the left and right side walls of the rear clamping member are respectively provided with a left sliding groove and a right sliding groove adapted to the guide slider. Near its lower end, a connecting transition block is fixedly installed on the front side wall of the rear clamping member. The connecting transition block is formed with mutually interpenetrating waist-shaped avoidance holes for inserting the front clamping member and a transverse installation hole for inserting the pin shaft. The front clamping member is vertically inserted into the waist-shaped avoidance hole and penetrated by the pin shaft, and when it is subjected to a pushing force, it can perform a swinging motion toward / backwards from the rear clamping member. The upper guide bearing is used to transmit a lateral pushing force to the front clamping member, and it is sleeved on the front clamping member. When the ironing glove is completely fitted relative to the four-finger contoured arm, the rear clamping piece and the front clamping piece are respectively located at the rear and front of the back of the glove, and the upper guide bearing is close to the rear clamping piece due to external force intervention. At the same time, the front clamping piece is forced to perform a swinging motion toward the rear clamping piece until the back of the glove is clamped oppositely.

[0017] As a further improvement of the technical solution disclosed in the present invention, the four-finger ironing and combing equipment includes a downstream six-degree-of-freedom robot arm, a four-finger hanging ironing device and a four-finger combing and unfolding tooling. The downstream six-degree-of-freedom robot arm is used to load the four-finger hanging ironing device, and it is arranged near the downstream multi-station circular conveyor. The four-finger combing and unfolding tooling is assembled into one with the four-finger hanging ironing device, and in the process of ironing the gloves, under its action, the four fingers of the gloves are repeatedly stretched and flattened. When the semi-finished glove ironing product is completed relative to the four-finger hand mold accompanying jig set, and at a certain moment in the process of performing the circular circulation, the downstream multi-station circular conveyor briefly stops, and during this period, the four fingers of the gloves are subjected to high-temperature ironing operation with the help of the four-finger hanging ironing device, and alternately, the four fingers of the gloves are stretched and flattened with the help of the four-finger combing and unfolding tooling.

[0018] As a further improvement of the technical solution disclosed by the present invention, the four-finger hanging 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 water vapor circulation holes are evenly distributed on the middle flattening section. During the ironing process, the water inside the hanging iron generates scorching hot water vapor due to heat, and reaches the four-finger part of the glove through the water vapor circulation holes, and the fabric fiber structure thereof is softened. At the same time, the middle flattening section continuously presses and flattens 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 glove. The four-finger spreading tooling includes a connecting transition piece, a left-side spreading plug board, a middle spreading plug board, a right-side spreading plug board, a left-side compression spring, a middle compression spring, a right-side compression spring, and a hinge shaft. The connecting transition piece is assembled with the ironing piece in a detachable manner. Near its top region, an installation boss is formed by continuously extending backward from the rear side wall of the connecting transition piece. Along its width direction, a left-side installation groove for installing the left-side spreading plug board, a middle installation groove for installing the middle spreading plug board, and a right-side installation groove for installing the right-side spreading plug board are sequentially opened on the installation boss. And a horizontal installation hole for installing the hinge shaft and communicating with the left-side installation groove, the middle installation groove, and the right-side installation groove is opened on the installation boss. The left-side compression spring, the middle compression spring, and the right-side compression spring all use the connecting transition piece as the installation base and are used to pull the tails of the left-side spreading plug board, the middle spreading plug board, and the right-side spreading plug board one by one. When the left-side spreading plug board, the middle spreading plug board, and the right-side spreading plug board are completely initially installed and positioned relative to the left-side installation groove, the middle installation groove, and the right-side installation groove, the hinge shaft is inserted into the horizontal installation hole, and the left-side spreading plug board, the middle spreading plug board, and the right-side spreading plug board are assembled with the installation boss in a hinged manner. And during the process of ironing and stretching the four-finger part of the glove, according to the specific situation of the four-finger part to be ironed, the left-side spreading plug board, the middle spreading plug board, and the right-side spreading plug board perform a yaw movement adaptively due to the reaction force, and accordingly, the compression amounts of the left-side compression spring, the middle compression spring, and the right-side compression spring change synchronously.

[0019] In practical applications, the glove ironing and shaping production line disclosed by the present invention can at least achieve the following beneficial technical effects: specifically:

[0020] 1) The automatic station change, ironing and shaping of gloves are realized, which not only greatly shortens the total post-processing time of gloves after forming, but also each glove ironing and shaping production line only needs two workers to meet the daily operation needs, one of which is used to supply gloves to the glove big finger flattening and shaping unit in sequence, and the other worker is used to supply the ironed semi-finished gloves to the glove four-finger ironing and flattening unit. From the above description, it can be seen that the number of workers can be reduced, which is conducive to reducing labor costs, and the labor intensity can also be significantly reduced, and the requirements for workers' labor skills and work experience are relaxed;

[0021] 2) In view of the unique design of gloves and the different acceptance standards for each component, the large finger flattening and shaping operation and the four-finger ironing and flattening operation are independent of each other and belong to different process stages. This is not only conducive to ensuring that the gloves that have undergone post-processing have extremely high finished product quality, but also can effectively avoid the appearance of devices and equipment with multiple functions, complex design structure, great assembly difficulty and unstable output in the glove ironing and shaping production line.

DETAILED DESCRIPTION

[0048] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "front", "back", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0049] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 The three-dimensional schematic diagram of the glove ironing and shaping production line disclosed in the present invention is shown. It can be seen that it is mainly composed of a glove big finger flattening and shaping unit 1, a glove ironing semi-finished product unloading device 2, a glove ironing semi-finished product conveying platform 3, a glove four-finger ironing and flattening unit 4, a glove ironing finished product unloading device 5 and a glove ironing finished product conveying platform 6.

[0050] In practical applications, the glove ironing and shaping production line follows the following steps to implement the glove ironing operation:

[0051] S1, manually supplying gloves to the glove big finger flattening and shaping unit 1, and performing big finger flattening and shaping operation on the gloves to form the glove ironing semi-finished products;

[0052] S2, using the glove ironing semi-finished product unloading device 2 to transfer the glove ironing semi-finished product from the glove big finger flattening and shaping unit 1 to the glove ironing semi-finished product conveying platform 3;

[0053] S3, manually transferring the semi-finished glove ironing products from the semi-finished glove ironing products conveying platform 3 to the four-finger glove ironing and flattening unit 4, so as to perform four-finger ironing and stretching operations and glove back ironing and stretching operations on the semi-finished glove ironing products, so as to form finished glove ironing products;

[0054] S4, the finished glove ironing products are transferred from the glove four-finger ironing and flattening unit 4 to the finished glove ironing products conveying platform 6 by means of the finished glove ironing product unloading device 5, and then continue to flow to the packaging process.

[0055] In the technical solution disclosed in the present embodiment, the automatic station conversion, ironing and shaping operations of the gloves are realized, thereby not only greatly shortening the total post-processing time of the gloves after forming, but also each glove ironing and shaping production line only needs to be equipped with two workers to meet the daily operation needs, one of which uses a manual set method to supply the gloves to the glove big finger flattening and shaping unit 1 in sequence, and the other worker uses a manual set method to supply the ironed semi-finished gloves to the glove four-finger ironing and flattening unit 4. From the above description, it can be seen that the number of workers can be reduced, which is conducive to reducing the labor cost, the labor intensity can also be significantly reduced, and the requirements for the workers' labor skills and work experience are relaxed.

[0056] It should be emphasized here that, in view of the unique design of gloves and the different acceptance standards for each component, the large finger flattening and shaping operation and the four-finger ironing and flattening operation are independent of each other and belong to different process stages. This is not only conducive to ensuring that the gloves that have undergone post-processing have extremely high finished product quality, but also can effectively avoid the appearance of devices and equipment with multiple functions, complex design structure, great assembly difficulty and unstable output in the glove ironing and shaping production line.

[0057] Figure 2 The schematic diagram of the glove big finger flattening and shaping unit in the glove ironing and shaping production line disclosed in the present invention is shown. It can be seen that it is mainly composed of several parts such as the upstream multi-station circular conveyor 11, the big finger hand model accompanying jig 12 and the glove big finger stretching device 13. The upstream multi-station circular conveyor 11 uses continuous directional movement to realize the transportation of the big finger hand model accompanying jig 12. In actual application, the big finger hand model accompanying jig 12 changes its position due to the driving force from the upstream multi-station circular conveyor 11, and the auxiliary glove big finger stretching device 13 flattens the glove big finger through "pulling" and "pressing" actions.

[0058] like Figure 3 As shown in the figure, the thumb hand model accompanying fixture 12 is mainly composed of an upstream base 121, a thumb profiling arm 122, and a thumb electric heating unit. The upstream base 121 is directly carried by the upstream multi-station circular conveyor 11, and is fixed to the carrier of the upstream multi-station circular conveyor 11 in a detachable manner. The thumb profiling arm 122 is assembled with the upstream base 121 in an insertion manner, and after assembly, it maintains an upright posture, which is conducive to workers to put on gloves more quickly. Figure 3 It can also be clearly seen that on one side of the upstream base 121, the carrier platform of the upstream multi-station circular conveyor 11 is equipped with a power socket to supply power to the thumb electric heating unit. In actual application, the thumb electric heating unit is used to supply heat to the thumb contour arm 122, so that the thumb contour arm 122 can be heated to a desired temperature value, and the fabric or fiber of the thumb part (eccentric thumb part) of the glove mounted thereon can be softened, which helps to reduce the difficulty of subsequent stretching and shaping.

[0059] like Figure 4As shown in the figure, the glove thumb stretching device 13 is mainly composed of several parts such as an upstream six-degree-of-freedom mechanical arm 131 and a thumb stretching tool 132. The upstream six-degree-of-freedom mechanical arm 131 is used to carry the thumb stretching tool 132, and it is arranged near the upstream multi-station circular conveyor 11. The thumb stretching tool 132 is detachably fixed to the execution end of the upstream six-degree-of-freedom mechanical arm 131. In actual application, when the glove is completely assembled relative to the thumb contouring arm 122 and at a certain moment in the process of executing the circular circulation, the upstream multi-station circular conveyor briefly stops, and during this period, the upstream six-degree-of-freedom mechanical arm 131 is in motion, and the thumb stretching tool 132 is able to realize the glove thumb stretching and shaping operation.

[0060] As is known, according to design common sense, the thumb stretching tool 132 can adopt a variety of design structures to achieve the stretching and shaping operation of the thumb of the glove. However, here we recommend an implementation scheme with a simple design structure, easy manufacturing and implementation, and relatively low implementation cost, specifically: Figure 5 , 6 As shown in Figures 7 and 8, the thumb stretching tooling 132 is mainly composed of several parts such as a parallel finger cylinder 1321, a left stretching assembly 1322 and a right stretching assembly 1323. The parallel finger cylinder 1321 is installed at the execution end of the upstream six-degree-of-freedom robot 131, and its left and right fingers are respectively assembled with the left stretching assembly 1322 and the right stretching assembly 1323 in a one-to-one correspondence and in a detachable manner. The left stretching assembly 1322 is composed of a left plastic mounting plate 13221 and a left stretching plastic liner 13222, and is detachably combined into one. The right stretching assembly 1323 is composed of a right plastic mounting plate 13231 and a right stretching plastic liner 13232, and is detachably combined into one. A left thumb stretching profiling notch 132221 and a right thumb stretching profiling notch 132321 are formed on the working surfaces of the left stretching plastic liner 13222 and the right stretching plastic liner 13232 respectively, which are matched with the thumb profiling arm 122. Before the thumb part of the glove is formally stretched, the left stretching assembly 1322 and the right stretching assembly 1323 are closed together, and the left thumb stretching profiling notch 132221 and the right thumb stretching profiling notch 132321 are closed to form thumb stretching profiling notches that are conducive to stretching and shaping the thumb shape of the glove.

[0061] When the thumb hand model accompanying fixture 12 flows to the thumb stretching station, the upstream six-degree-of-freedom robot arm 131 moves to change the posture until the parallel finger cylinder 1321 is adjusted to a horizontal state, and then the upstream six-degree-of-freedom robot arm 131 continues to move to drive the parallel finger cylinder 1321 to perform reciprocating displacement along the up and down direction, so that the thumb of the glove can repeatedly enter / escape from the thumb stretching profiling gap surrounded by the left stretching assembly 1322 and the right stretching assembly 1323, and in this process, the thumb electric heating unit in the thumb profiling arm 122 continuously generates heat energy due to power, and the thumb profiling arm 122 is heated to the expected range, and the thumb part of the glove is softened due to the high temperature. At the same time, the thumb stretching tooling 132 performs reciprocating lifting and lowering motions under the driving force of the upstream six-degree-of-freedom robot arm 131, and the thumb stretching profiling gap can reciprocately pass over the thumb part of the glove.

[0062] Figure 8 , Fig. 9 The three-dimensional schematic diagram and the partial enlarged diagram of the four-finger ironing and flattening unit of the glove in the glove ironing and shaping production line disclosed in the present invention are respectively shown. It can be seen that it is mainly composed of a downstream multi-station circular conveyor 41, a four-finger hand mold accompanying fixture 42, a rear interference guide component 43, a front interference guide component 44, a magnetic attraction component 45, and a four-finger ironing and combing device 46. Among them, the four-finger hand mold accompanying fixture 42 changes its position due to the driving force from the downstream multi-station circular conveyor 41, and the four-finger ironing and combing device 46 is assisted to flatten the gloves through "pulling", "pressing" and "spraying". The front interference guide component 44 is used to standardize and guide the action process of whether the four-finger hand mold accompanying fixture 42 clamps the glove hemming cuff, and it is arranged on one side of the downstream multi-station circular conveyor 41. The rear interference guide component 43 is used to regulate and guide the movement process of whether the four-finger hand model accompanying fixture 42 is raised or lowered, and it is kept in parallel with the front interference guide component 44 (such as Fig.13 , 14 ).

[0063] like Fig.10As shown in the figure, the four-finger hand model accompanying fixture 42 is mainly composed of a downstream base 421, a four-finger profiling arm 422, a guide slider 423, a glove hemming cuff clamping assembly 424, a lower guide bearing 425 and a four-finger electric heating unit. Among them, the downstream base 421 is directly carried by a multi-station circular conveyor. The four-finger profiling arm 422 is assembled with the base 421 in an insertion manner, and after the assembly is completed, it maintains an upright posture. Four profiling fingers are formed at the free end of the four-finger profiling arm 422 to correspondingly cover the little finger, ring finger, middle finger and index finger of the glove. The guide slider 423 is fixed to the four-finger profiling arm 422 in a detachable manner and is located at the front side of the four-finger profiling arm 422. The glove hemming cuff clamping assembly 424 is assembled with the four-finger profiling arm 422 by means of the guide slider 423. The lower guide bearing 425 is used to transmit the drag force to the glove hemming cuff clamping assembly 424, and it is installed on the glove hemming cuff clamping assembly 424. Fig.10 It can also be clearly seen that on one side of the downstream base 421, the carrier platform of the downstream multi-station circular conveyor 41 is equipped with a power socket to supply electric energy to the four-finger electric heating unit. The four-finger electric heating unit is used to supply heat to the four-finger contour arm 422, so that the four-finger contour arm 422 can be heated to the expected temperature value, and the fabric or fiber of the four fingers, the palm and the back of the hand of the glove mounted thereon can be softened, which is conducive to reducing the difficulty of subsequent stretching and shaping. When it is necessary to stretch the glove cuff, the glove cuff clamping assembly 424 is activated to clamp the glove cuff, and the lower guide bearing 425 serves as the action guide for the glove cuff clamping assembly 424 to perform relative height position adjustment, and the back of the glove is stretched and flattened due to the drag force, or the back of the glove is restored to a free hanging state due to the loss of the drag force.

[0064] In actual application, the four-finger hand model accompanying jig 42 changes its position due to the driving force from the downstream multi-station circular conveyor 41, and the auxiliary four-finger ironing and combing device 46 flattens the gloves through "pulling", "pressing" and "spraying". Specifically, after the gloves to be ironed are assembled relative to the four-finger contoured arm 422, and the glove hemming cuff clamping assembly 424 is activated to clamp the hemming cuff of the glove, the lower guide bearing 425 is lowered due to the external force from the rear interference guide assembly 43. Under the guidance of the guide slider 423, the glove hemming cuff clamping assembly 424 performs a directional downward movement. In this process, the fabric or fiber of the four fingers, palm and back of the hand of the glove is softened due to the high temperature. At the same time, the four fingers and back of the hand of the glove are flattened due to the tensile force.

[0065] By adopting the above technical solution, on the one hand, in the process of the four-finger hand mold accompanying fixture 42 performing the station change due to the driving force from the downstream multi-station circular conveyor 41, the back of the glove is always kept in a stretched state, and the stretching force is kept at a constant value within the set time period, so that during the period when the four-finger ironing and combing device 46 takes effect, the back of the glove can be kept in the expected flattened state, which lays a good foundation for the subsequent ironing and shaping operation, and finally ensures that the finished gloves meet the factory acceptance standards; on the other hand, according to the requirements of the specific process of the gloves, when the stretching force value or duration of the back of the glove needs to be adjusted, it is only necessary to change the movement trajectory of the lower guide bearing 425, and the whole implementation process is convenient and fast.

[0066] like Fig.11 As shown in the figure, the glove hemming cuff clamping assembly 424 is mainly composed of a rear clamping member 4241, a front clamping member 4242, a connecting transition block 4243, a pin 4244, and an upper guide bearing 4245. In order to adapt to the guide slider 423, a left sliding groove 42411 and a right sliding groove are respectively provided on the left and right side walls of the rear clamping member 4241. A connecting transition block 4243 is fixedly mounted on the front side wall of the rear clamping member 4241 near its lower end. Fig.10 As shown in FIG. 4 , the front side wall of the four-finger contour arm 422 extends backward to form a sink. The guide slider 423 is embedded in the sink and fixed by means of screws. Fig.12 As shown in the figure, the connecting transition block 4243 is formed with mutually interpenetrating waist-shaped avoidance holes 42431 for inserting the front clamping member 4242, transverse installation holes 42432 for inserting the pin 4244, and bearing installation columns 42433 for installing the lower guide bearing 425. The front clamping member 4242 is vertically inserted into the waist-shaped avoidance holes 42431 and penetrated by the pin 4244, and when it is subjected to the pushing force, it can perform a swinging motion toward / backwards from the rear clamping member 4241. The upper guide bearing 4245 is used to transmit the lateral pushing force to the front clamping member 4242, and it is sleeved on the front clamping member 4242. When the glove to be ironed is completely fitted onto the four-finger contoured arm 422, the rear clamping member 4241 and the front clamping member 4242 are respectively located at the rear and front of the back of the glove, and the upper guide bearing 4245 is approached to the rear clamping member 4241 due to the external force interference from the front interference guide assembly 44. At the same time, the front clamping member 4242 is forced to perform a swinging motion toward the rear clamping member 4241 until the cuff of the glove is clamped oppositely.

[0067] From the above description, it can be seen that the opening and closing action process of the glove hemming cuff clamping assembly 424 is completely intervened by the front interference guide assembly 44, and in the process of the upper guide bearing 4245 performing the yaw movement, the opening and closing degree between the rear clamping member 4241 and the front clamping member 4242 changes, thereby realizing / releasing the opposite clamping of the glove hemming cuff. In this way, on the one hand, according to the requirements of the specific process of the gloves, when the clamping force or clamping time of the glove hemming cuff needs to be adjusted, it is only necessary to adjust the structural form of the front interference guide assembly 44, thereby changing the yaw motion trajectory of the lower guide bearing 425; on the other hand, under the premise of making the four-finger hand model accompanying fixture 42 have a very simple design structure and a faster action response speed, the on-line clamping design goal of the glove hemming cuff clamping assembly 424 is achieved, that is, within a certain period of time when the four-finger hand model accompanying fixture 42 performs a circular motion, the glove hemming cuff clamping assembly 424 can stably and reliably clamp the glove hemming cuff.

[0068] like Fig.15 As shown in the figure, the rear interference guide assembly 43 is mainly composed of a rear support frame 431 and a rear interference guide plate 432. Among them, the rear interference guide plate 432 is used to interfere and guide the lower guide bearing 425, and it is supported by the rear support frame 431. Along the left-to-right direction, the rear interference guide plate 432 is sequentially connected by a left-placed upwardly inclined guide section 4321, a middle flat section 4322 and a right-placed upwardly inclined guide section 4323. During the rolling of the lower guide bearing 425 through the left-placed upwardly inclined guide section 4321, it gradually lowers its relative height position due to the guidance of the left-placed upwardly inclined guide section 4321, and the glove hemming cuff clamping assembly 424 is able to perform a downward movement in a directional manner. In this process, the hemming cuff of the glove is gradually stretched and flattened due to the drag force. When the lower guide bearing 425 rolls through the middle flat section 4322, the back of the glove is always kept in a stretched and flattened state, which paves a good foundation for the smooth development of the four-finger ironing and combing device 46 to perform the ironing and flattening action process of the glove. When the lower guide bearing 425 rolls through the right-positioned upwardly inclined guide section 4323, it loses its guiding restriction, and the glove hemming cuff clamping assembly 424 gradually releases the dragging and traction on the back of the glove. At the same time, the glove hemming cuff clamping assembly 424 releases the opposite clamping on the back of the glove.

[0069] like Fig.16As shown in the figure, the front interference guide assembly 44 is mainly composed of a front support frame 441 and a front interference guide plate 442. Among them, the front interference guide plate 442 is used to interfere and guide the upper guide bearing 4245, and it is supported by the front support frame 441. Along the left to right direction, the front interference guide plate 442 is sequentially connected by a left outward guide section 4421, a middle vertical section 4422 and a right outward guide section 4423. During the rolling of the upper guide bearing 4245 through the left outward guide section 4421, it is gradually approached to the rear clamping member 4241 due to the guidance of the left outward guide section 4421, and the front clamping member 4242 is forced to perform a swinging motion towards the rear clamping member 4241 to clamp the cuff of the glove. During the period when the upper guide bearing 4245 rolls through the middle vertical section 4422, the cuff of the glove is always maintained in a clamped state and maintained for a desired period of time, which is conducive to the design purpose of pulling the glove downward by adjusting the relative height position of the glove cuff clamping assembly 424. After the glove is ironed and shaped, the upper guide bearing 4245 rolls through the right-positioned outward-inclined guide section 4423, and loses its guiding restriction. The front clamping piece 4242 automatically performs a swinging motion opposite to the rear clamping piece 4241 to release the clamping of the glove cuff.

[0070] According to feedback from the on-site commissioning personnel, the following problems were discovered during the commissioning of the first generation of glove ironing and shaping production line: After the gloves were ironed, flattened and shaped, the glove hemming cuff clamping assembly 424 could not promptly release the opposite clamping of the glove hemming cuff, causing considerable trouble to the subsequent unloading of finished gloves. The reason for this is that in the first generation design, when the front clamping member 4242 completely passed through the front interference guide plate 442 and lost interference and guidance, the front clamping member 4242 used the deflection torque generated by its own weight to achieve reverse deflection. However, due to the influence of external exciting force and the mutual engagement between the front clamping member 4242 and the rear clamping member 4241, the phenomenon of not being able to open and close smoothly in time often occurred. In view of this, as a further optimization of the above technical solution, such as Figure 8 As shown in FIG. 1 , the glove four-finger ironing and flattening unit 4 is further provided with a magnetic attraction component 45. The magnetic attraction component 45 is used to reversely attract the front clamping member 4242, and is located downstream of the rear interference guide component 43 and the front interference guide component 44. Fig.17As shown in the figure, the magnetic attraction component 45 is mainly composed of several parts such as the right support frame 451, the load beam 452 and the NdFeB magnet column 453. The load beam 452 is supported by the right support frame 451. The NdFeB magnet column 453 used for directly magnetically attracting the front clamp 4242 is embedded in the load beam 452 as a whole. On the rear side wall of the load beam 452, there are formed a plurality of embedded grooves (not shown in the figure) for embedding the NdFeB magnet column 453 and arranged in a linear array along its length direction. In actual application, after the gloves are stretched and flattened, the four-finger hand mold accompanying jig 42 continues to circulate until the glove stretching is forced to release the station. At this moment, the four-finger hand mold accompanying jig 42 is relative to the magnetic attraction component 45, and the front clamping part 4242 is forced to perform a yaw motion opposite to the rear clamping part 4241 due to the attraction from the neodymium iron boron magnet column 453 until the glove hemming cuff clamping component 424 releases the clamping of the glove hemming cuff.

[0071] like Fig.18 As shown in , the four-finger ironing and combing equipment 46 is mainly composed of several parts such as a downstream six-degree-of-freedom robot arm 461, a four-finger hanging ironing device 462 and a four-finger combing and unfolding tooling 463. Among them, the downstream six-degree-of-freedom robot arm 461 is arranged near the downstream multi-station circular conveyor 41, and it is located on a shelf. The four-finger hanging ironing device 462 is fixed to the execution end of the downstream six-degree-of-freedom robot arm 461. The four-finger combing and unfolding tooling 463 is assembled with the four-finger hanging ironing device 462. In actual application, when the glove ironing semi-finished product is assembled relative to the four-finger hand mold accompanying fixture 42, and at a certain moment in the process of circular circulation, the downstream multi-station circular conveyor 41 is briefly paused, and during this period, the four-finger hanging ironing device 462 is used to perform high-temperature ironing operations on the four-finger parts of the gloves, and alternately, the four-finger combing and unfolding tooling 463 is used to perform stretching and flattening operations on the four-finger parts of the gloves.

[0072] In the above technical solution, the four-finger ironing and combing equipment 46 applies a multi-degree-of-freedom robot arm with extremely excellent flexibility and motion accuracy. More importantly, the four-finger hanging ironing device 462 and the four-finger combing and spreading tooling 463 are integrated with the downstream six-degree-of-freedom robot arm 461, so that the four-finger ironing and combing equipment 46 has 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.

[0073] like Fig.19 , 20 As shown in FIG. 4 , the four-finger hanging ironing device 462 is mainly composed of a hanging iron 4621 and an ironing member 4622. Fig.21As shown, the cross-section of the ironing piece 4622 is in a "U" shape, which is sequentially connected by a left stop section 46221, a middle flattening section 46222, and a right stop section 46223. The middle flattening section 46222 is in contact with and fixed to the ironing surface of the hanging iron 4621. A plurality of steam circulation holes 462221 are evenly distributed on the middle flattening section 46222. During the ironing process, the water inside the hanging iron 4621 is heated to generate hot steam, which reaches the four-finger part of the glove through the steam circulation holes 462221, and the fabric fiber structure thereof is softened. At the same time, the middle flattening section 46222 continuously presses and smooths the back of the glove. During this process, the left stop section 46221 and the right stop section 46223 cooperate to regularize the side edges of the glove. In practical applications, under the action guidance of the downstream six-degree-of-freedom robotic arm 461, the four-finger hanging ironing device 462 and the four-finger combing and spreading tooling 463 alternately function. And during this time period, the four-finger hanging ironing device 462 and the four-finger combing and spreading tooling 463 both need to act repeatedly for many times until the four fingers of the glove are combed and flattened, and the back of the hand is ironed and shaped, ultimately ensuring that the finished glove meets the factory acceptance standards.

[0074] Similarly, as Fig.19 , 20 shown, the four-finger combing and spreading tooling 463 is mainly composed of a connecting and transitional part 4631, a left stretching and inserting plate 4632, a middle stretching and inserting plate 4633, a right stretching and inserting plate 4634, a left compression spring 4635, a middle compression spring 4636, a right compression spring 4637, and a hinge shaft 4638, etc. The connecting and transitional part 4631 is assembled with the ironing piece 4622 in a detachable manner. As Figure 22-24As shown in , near the top region, the rear side wall of the connecting transition piece 4631 continues to extend backward to form a mounting boss 46311. Along the width direction, the mounting boss 46311 is provided with a left mounting groove 463111 for mounting the left extension plug plate 4632, a middle mounting groove 463112 for mounting the middle extension plug plate 4633, and a right mounting groove 463113 for mounting the right extension plug plate 4634. The mounting boss 46311 is provided with a transverse mounting hole 463114 for mounting the hinge shaft 4638 and intersecting the left mounting groove 463111, the middle mounting groove 463112, and the right mounting groove 463113. The left compression spring 4635, the middle compression spring 4636, and the right compression spring 4637 are all installed on the connection transition piece 4631 as the installation basis, and are used to pull the tail ends of the left extension plug plate 4632, the middle extension plug plate 4633, and the right extension plug plate 4634 one by one. After the left extension plug plate 4632, the middle extension plug plate 4633, and the right extension plug plate 4634 are completely and initially installed and positioned relative to the left installation groove 463111, the middle installation groove 463112, and the right installation groove 463113, the hinge shaft 4638 is inserted into the horizontal installation hole 463114, and the left extension plug plate 4632, the middle extension plug plate 4633, and the right extension plug plate 4634 are able to achieve an articulated assembly with the installation boss 46311. And in the process of ironing, stretching and flattening the four fingers of the glove, according to the specific situation of the four fingers to be ironed, the left stretching plug 4632, the middle stretching plug 4633 and the right stretching plug 4634 adaptively perform the yaw motion due to the reaction force, and accordingly, the compression amount of the left compression spring 4635, the middle compression spring 4636 and the right compression spring 4637 changes 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 of the four fingers due to excessive pressing force.
