Description

Seam expansion device for clothing

The present invention relates to a seam expansion device for clothing, which is used to form a contracted state by overlapping the seams of two pieces of fabric such as sportswear, leggings, pantyhose, tights, pajamas, etc. When the two fabric parts in the seamed clothing are unfolded to both sides in the direction orthogonal to the longitudinal direction of the seam, the edges of the two unfolded fabric parts are flat-stitched. The joints in the contracted state expand.

Taking the sportswear SW shown in FIG. 11 as an example of the target clothing, the sportswear SW is illustrated by arrows a, in FIG. 11 along the fabric travel direction Y (refer to FIG. 13) by using a seaming machine. The points shown in b, c, d, e, and f form a seam S classified as JIS mark mark class 500, and are made by overlocking. In the JIS mark mark class 500, for example, a total of 3 threads consisting of 1 needle thread NT and 2 upper and lower thread hook threads ULT and LLT, the structure of the seam S classified as JIS mark mark 505 is shown in Figure 12 , When seaming, overlap the upper fabric portion UW and the lower fabric portion LW up and down in the direction orthogonal to the longitudinal direction of the seam, for example, expand left and right, thereby the ends of the left and right fabric portions UW and LW The edge UWe and LWe become the state of flat seam as shown in Fig. 13 and Fig. 14.

As mentioned above, by setting the edges UWe and LWe of the fabric parts UW and LW on the left and right after the seam stitching into a flat seam state, the seam part will not protrude to the back of the clothes in contact with the skin. , The cloth part can be smoothly stitched to improve the wearing feeling, and the edge of the cloth part will not be exposed to the surface of the clothes, and clothes with excellent aesthetics can be obtained.

In addition, when the target clothing is a fabric material rich in elasticity and stretchability such as sportswear or pantyhose mentioned above, threads with high elongation such as wool-like yarn are often used as needle threads and thread hook threads. Therefore, the seam formed by the seam which is classified as JIS mark mark grade 505 is affected by the elasticity and stretchability of the fabric part and the high elongation of the needle thread and the thread hook thread and becomes a strong contraction state. Expand the seam in such a way that the fabric part of the seam is spread to the left and right of the seam and the edges of the left and right fabric parts become the flat seam state shown in Figure 13 and Figure 14, and the seam must be in a strong contraction state. The seam is strong enough to resist the contraction force and the stronger stretching force.

[The problem to be solved by the invention]

Previously, there was no special machine that expands the seam in a strong contraction state as described above over the full length of its longitudinal direction. Therefore, the expansion of the seam is fully dependent on manual labor. Therefore, in order to expand the seam, it is necessary to firmly grasp the two pieces of fabric with both hands and apply a strong tensile force to the two directions orthogonal to the longitudinal direction of the seam, which requires a huge amount of labor (manpower). In addition, when there are seams formed in many places of a piece of clothing, or when the length of the seams is very long, in order to expand all the many or long seams, a very large amount of work and Long time. As a result, there are problems in that the productivity of specific clothes is likely to decrease, and it is difficult to expand the seams beautifully over the full length of the clothes to obtain clothes with good wearing feeling and processing.

The present invention was completed in view of the above-mentioned actual situation, and its purpose is to provide a seam expansion device for clothing, which does not require special labor after the seam seam, and only requires a minimum amount of work. Time, the seam can be expanded reliably and efficiently over its full length without excessive friction or brute force applied to the fabric to cause damage, and the expansion of the seam can be performed very smoothly and efficiently. And it can help improve the wearing feeling and the productivity of well-processed clothes. [Means to Solve the Problem]

In order to achieve the above-mentioned object, the seam expansion device for clothing of the present invention is characterized in that it is provided with a cloth part feeding part attached to a seam movement guide groove, which is used to seam the seam of the two overlapping cloth parts. When the two fabric parts in the garment with the seam in the contracted state are expanded to both sides in the direction orthogonal to the longitudinal direction of the seam, the seam in the contracted state is along the seam. The two pieces of fabric are guided and fed into the longitudinal direction; and a pair of forced-feeding devices for the fabric section, which are clamped and held to be fed to the joint while the guide groove is moved along the seam to guide the above-mentioned seam. The two cloth parts of the cloth part feeding part and the two cloth parts are forcibly transferred in the longitudinal direction of the seam, and the pair of cloth part forced-feeding devices gradually increase the ends of the feeding direction at the opposing distance The arrangement is based on the degree of the part, and the above-mentioned pair of cloth part forced transfer devices are constructed in such a way that at least the opposite distance between the end parts of the transfer direction can be changed; When the two fabric portions in the clothes are transferred by the pair of fabric portion forced transfer devices, the seams in the contracted state are expanded so that the edges of the two unfolded fabric portions become flat stitches, and Connected to the transfer end of the pair of fabric part forced transfer devices is provided with a detector that detects whether the seam has been expanded by the pair of fabric part forced transfer devices. The front end of the transfer direction of the clothes is from the above A pair of fabric part forced transfer devices send out; and a forced discharge transfer device for clothes that have completed seam expansion, which can be switched to contact with the clothes discharged from the pair of fabric part forced transfer devices and move the clothes to the seams. The first state of forced discharge and transfer in the longitudinal direction and the second state of separation from the above-mentioned clothes without forced discharge and transfer of the clothes. The forced discharge and transfer device of the above-mentioned clothes that have completed the seam expansion is detected based on the detection of the above-mentioned detector It operates to switch from the second state to the first state. [Effects of Invention]

According to the seam expansion device for clothing of the present invention having the above-mentioned characteristics, the two fabric parts with seams formed by seaming are moved to both sides of the direction orthogonal to the longitudinal direction of the seam In the unfolded state, the two pieces of fabric are inserted into the seam moving guide groove with the seam in the contracted state and are fed into the moving guide groove along the guide groove and set in the fabric section feeding part, thereby connecting the two pieces of fabric. The cloth piece part is clamped and held by the pair of cloth part transfer devices and is forcibly transferred in the longitudinal direction of the seam. In addition, during this forced feeding, the opposing spacing of the aforementioned pair of fabric part forced feeding devices gradually increases. Therefore, as the forced feeding progresses, the two fabric parts can be pulled in a direction orthogonal to the longitudinal direction of the seam. Extend force, and the seam expands mechanically and automatically. Therefore, it only takes a minimum amount of work and time such as unfolding the two fabric parts after seaming and placing them in the feeding part of the fabric part, and there is no need to hold the two fabric parts tightly with both hands to align the seams The two directions orthogonal to the long side direction apply strong stretching manpower and other work labor, and the seam can be expanded reliably and efficiently over the full length of the seam, and the fabric part has a smooth back surface with a higher wearing feeling and beautiful appearance. Clothing with excellent surface properties.

In addition, since the opposing spacing of the pair of fabric portion transfer devices can be arranged to gradually increase the degree of the end portion of the transfer direction, the two fabric portions after the seaming can be forcibly transferred, and the two fabric portions are connected to each other. The seam exerts a stretching force orthogonal to its longitudinal direction, so for example, a fixed expansion is used in which the part of the cloth including the seam is moved along the gradient cam slidingly during forced feeding to give the above-mentioned stretching force. A device, or by a drive rotating body that sequentially gathers the forcibly transferred fabric part including the seam and rotates and transfers the gathered fabric part to one of the front and back directions of the fabric part to give the above-mentioned stretching force. Compared with the case of the rotary retractable expansion device, it does not apply excessive friction or brute force to the fabric, so the fabric will not be scratched or partially damaged, and can be well processed for seam expansion.

In addition, at the downstream of the aforementioned pair of fabric portion forced-feeding devices, the front end of the clothes whose seams are expanded by the pair of fabric portion forced-feeding devices can be sent out from the pair of fabric portion forced-feeding devices according to the forward end of the clothes in the direction of transfer. The detection action of the detector for detecting is to switch the forced discharging and transferring device of the clothes that are in the second state separated from the clothes and the expansion of the seam to the first state in contact with the clothes, and the completed seam is changed. The expanded clothes continue to be forcedly discharged and transferred in the longitudinal direction of the seam after the above-mentioned pair of fabric part forced-feeding devices, so that it can prevent the clothes that have completed the seam expansion from stagnating at the downstream of the pair of fabric part forced-feeding devices in the transfer direction And it will affect the transfer of subsequent clothes. Therefore, the following effect is exerted: the seam expansion operation for a large number of clothes can be performed very smoothly and efficiently, and the productivity of clothes with good wearing feeling and processing can be improved.

In the seam expansion device for clothing of the present invention, the forced discharge and transfer device for the clothing that has completed seam expansion is preferably based on the detection of the terminal portion of the transfer direction of the clothing that has completed seam expansion based on the detector.

Next, for the seam expansion device M using the clothing of the present embodiment constructed as described above, the seam is formed by using the seam of the seaming machine to form the shrinkage as shown in FIG. 12, which is classified as a JIS mark mark class 505 The state of clothing with seams S, for example, the action of expanding each seam S in the sportswear SW shown in FIG. 11 will be described.

First, by stepping on the foot pedal with the start switch turned on, and as shown in Figure 9, the upper loop belts 3LU, 3RU and the completed seams of the above-mentioned pair of left and right fabric part forced transfer devices 3L, 3R The substantial forced-discharge transfer part 35A in the forced-discharge transfer device 35 of the expanded clothes rises together. At this time, the upper ring belts 3LU and 3RU of the above-mentioned left and right pair of cloth part forced conveying devices 3L and 3R and the two cross-sectional circular ring belts 35L, 35R keeps the rotation stopped.

Then, by operating the foot pedal to the neutral position, as shown in FIG. 7, it becomes the following state: the upper ring belts 3LU, 3RU of the pair of left and right cloth part forced feeding devices 3L, 3R are lowered, and the upper part The conveying surfaces of the endless belts 3LU and 3RU are close to the lower conveying surfaces of the endless belts 3LL and 3RL, which clamp the left and right fabric parts holding the clothes and force them to be conveyed.

Then, by stepping on the foot pedal, the drive motor 20 is operated to force the upper loop belts 3LU, 3RU of the left and right pair of fabric part forced transfer devices 3L, 3R and the forced discharge of the above-mentioned garments whose seams have been expanded. The two cross-sectional circular endless belts 35L and 35R in the transfer device 35 simultaneously start to rotate.

In this state, in the fabric part of clothing SW such as sportswear with the seam S of the marking grade 505 classified as JIS, the upper and lower fabric parts UW and LW will be overlapped up and down when the seam is formed. The left and right sides of the seam S are unfolded, and the seam S in the contracted state is inserted into the seam moving guide groove 4S and is arranged in the cloth part feeding part 4 in such a manner that the seam S is guided and moved along the moving guide groove 4S.

As a result, the fabric portions UW and LW spread to the left and right sides are forcibly transferred via the forced feeding endless belt 19 and the two rollers 12L, 12R, and are fed into the left and right pair of fabric portions from the front end of the fabric portion. The upper and lower pairs of endless belts 3LU, 3LL, 3RU, and 3RL are clamped and held as shown in Fig. 6 in the forced feeding device 3L, 3R, and then the above-mentioned left and right fabric parts UW, LW are left and right. The pair of fabric part forced feeding devices 3L and 3R forcibly feed in the directions of arrows YL and YR, respectively.

At the time of this forced feeding, since the opposing distance between the aforementioned pair of forced feeding devices 3L and 3R gradually increases, as the forced feeding progresses, the left and right cloth parts UW, LW are given the length of the seam S. The stretching force in the direction perpendicular to the side direction will automatically and continuously expand the seam S in sequence. After passing through the left and right pair of fabric portion forced transfer devices 3L, 3R, the edges of the left and right fabric portions UW, LW UWe and LWe are in a flat seam state as shown in Figs. 13 and 14, and are processed into clothing SW such as sportswear with a smooth back surface with high wearing feeling and a surface with excellent aesthetics.

The front ends of the two fabric parts UW and LW (sportswear and other clothing SW) in the transfer direction of the expanded seam S in the above manner are sent out from the left and right pair of fabric part forced transfer devices 3L, 3R to the discharge transfer guide When the surface 2La is on, the detector 40 detects the front end. According to the detection action, the air cylinder 41 extends and drives the lifting platform 36 to descend, thereby as shown in FIG. The essential forced-discharge transfer part 35A of the forced-discharge transfer device 35 contacts the upper surface of the garment SW whose seam expansion has been completed, which is discharged from the above-mentioned pair of left and right fabric part forced-transfer devices 3L, 3R to the above-mentioned discharge transfer guide surface 2La. , And the clothing SW is forcedly discharged and conveyed in the longitudinal direction of the seam S, that is, the forced discharge and conveyance direction Z described above.

And, when the detector 40 detects the end of the transfer direction of the garment SW whose seam expansion has been completed, the air cylinder 41 contracts according to the detection action and drives the lifting platform 36 to rise, so that the completed connection The substantial forced discharge conveying portion 35A of the forced discharge conveying device 35 for clothes with expanded seams is separated to above the discharge conveying guide surface 2La, and on the other hand, the pedal is then stepped back to stop the The operation of the driving motor 20, and as shown in FIG. 9, the lifting member 30 is driven up by the air cylinder 28, and the transfer surfaces of the upper endless belts 3LU and 3RU are separated from the lower endless belts 3LL and 3RL to the upper side. Then, a gap 44 is formed between the opposite transfer surfaces of the upper endless belts 3LU, 3RU and the lower endless belts 3LL, 3RL.

In the state of FIG. 9, even if the garment SW whose seam expansion has been completed is a cylindrical garment such as sportswear as shown in FIG. 11, the cylindrical garment SW is fed into the cloth section through the gap 44 The upstream side of the part is quickly drawn out, and the same action as described above is repeated thereafter, thereby sequentially performing seam expansion operations on multiple pieces of clothing.

As described above, the seam expansion device M of the clothing of the present embodiment only requires the least amount of work to expand and install the fabric part after seaming to the left and right sides orthogonal to the longitudinal direction of the seam S. With time, and without the labor of exerting a strong stretching force by manpower, the seam S can be expanded reliably and efficiently over its full length, and a smooth back and beautiful appearance of the fabric part with a higher wearing feeling can be obtained. Clothing with excellent surface properties, even if it is sportswear SW or pantyhose, in most cases, elastic and stretchable fabric materials are used and high elongation threads such as wool-like yarn are used as needle threads and thread hooks. When the seam S becomes a strong contraction state due to the production relationship, the seam S can also be expanded automatically, surely, and evenly.

Especially because it can be arranged in such a way that the opposing spacing of the pair of fabric part transfer devices 3L and 3R gradually increases to the extent of the end part of the transfer direction, the left and right fabric parts UW and LW after the seaming are forcibly transferred and aligned The seam S connecting the two fabric parts UW and LW slowly applies a stretching force orthogonal to the longitudinal direction of the two fabric parts. A fixed expansion device in the form of sliding movement of the cam to impart the above-mentioned stretching force, or by sequentially folding up the forcibly transferred fabric part including the seam and rotating the collected fabric part to the front and back of the fabric part Compared with the case of the rotating retractable expansion device in the form of driving the rotating body in one direction to give the above-mentioned stretching force, it does not apply excessive friction or brute force to the fabric, so the fabric will not be scratched or partially damaged. Can perform well-processed joint expansion.

In addition, according to the degree of shrinkage of the seam S, the upper mounting base 15LU, 15RU and the lower mounting base 15LL, 15RL are rotated around the upper and lower axes of the upper guide pins 25LU, 25RU and the lower guide pins 25LL, 25RL, and are rotated by screws 26LU. , 26RU and screws 26LL, 26RL are fixed at any rotating position, so that the opposite spacing of the upper and lower pair of endless belts 3LU, 3LL and 3RU, 3RL in the transfer direction can be changed arbitrarily. Therefore, whether it is sportswear or pantyhose, etc., due to the use of elastic and stretchable fabric materials and the use of high elongation threads such as wool-like yarn as the relationship between the needle thread and the thread hook thread, various seams have undergone various changes. For clothing of any degree of shrinkage, its seams can be expanded reliably and appropriately and beautifully to produce well-processed clothing.

In addition, as in the present embodiment, the left and right pairs of forcible feeding devices 3L, 3R are respectively arranged with the feeding surfaces facing up and down as a pair of upper and lower endless belts 3LU, 3LL, 3RU, and 3RU. In the case of the 3RL configuration, the two fabric parts UW and LW, which are spread to the left and right sides after the seaming, are respectively clamped between the upper and lower pair of loop belts 3LU, 3LL, 3RU, and 3RL. Because of the transfer, the left and right fabric parts UW and LW can be forcibly transferred in a specific direction reliably and evenly, and the seam S can be evenly expanded to the left and right, and better processed clothes can be obtained.

In addition, as shown in this embodiment, in the next pair of endless belts 3LU, 3LL, 3RU, 3RL above the left and right pair of fabric portion forced feeding devices 3L, 3R, the upper endless belts 3LU, 3RU and the drive motor 6 interlocking connection is constructed by driving and rotating. On the other hand, the lower endless belts 3LL and 3RL are constructed by driven rotation, that is, non-driving, and the cloth part is sandwiched between the upper endless belts 3LU and 3RU. When the time transfer is moving in the same direction, the two fabric parts UW and LW spread to the left and right sides are sandwiched between a pair of oppositely arranged loop belts after the seaming, accompanied by the upper loop belt The driving rotation of 3LU and 3RU causes the lower loop belts 3LL and 3RL to rotate and forcefully transfer, so the left and right fabric parts UW and LW will hardly receive transfer resistance, and the specific connection with forced transfer can be performed reliably and smoothly. Seam expansion function.

Also, as shown in this embodiment, at the downstream of the aforementioned pair of fabric portion forced-feeding devices 3L, 3R, the seam is expanded by the pair of fabric portion forced-feeding devices 3L, 3R according to the pair of detectors 40 The front end of the clothes SW in the transfer direction is sent from the pair of cloth part forced-feeding devices 3L, 3R to detect the detection action, and forcedly discharge and transfer the clothes in the second state separated from the clothes that have completed the seam expansion. The substantial forced discharge transfer portion 35A in the device 35 is switched to the first state in contact with the clothing SW, whereby the clothing SW that has completed the seam expansion can continue to be forcedly discharged and transferred in the longitudinal direction of the seam, so that it can be avoided. The clothes SW that has completed the seam expansion stagnates downstream in the transfer direction of the pair of cloth part forced transfer devices 3L, 3R, and affects the transfer of the subsequent clothes. Thereby, the seam expansion operation can be performed very smoothly and efficiently on multiple pieces of clothing.

In addition, as shown in this embodiment, the forced ejection and transfer device 35 for the clothes whose seam expansion has been completed can be determined based on the movement of the terminal portion of the clothes SW whose seam expansion has been completed by the detector 40 in the transfer direction. It is automatically switched from the first state to the second state, so that the garment SW that has completed seam expansion can be removed from the expansion device M as soon as possible, and the expansion of the next garment can be started as soon as possible, thereby improving the expansion device M The use efficiency.

In addition, as shown in this embodiment, the forced discharge and transfer device 35 for the garments whose seams have been expanded is composed of a plurality of (two) cross-sectional circles arranged in a direction orthogonal to the longitudinal direction of the seam S The circular endless belts 35L and 35R are interlocked and connected to the drive motors 20 of the pair of cloth portion forced feeding devices 3L, 3R, so that the forced ejection and feeding devices 35 can be paired. The contact of the garment SW that has completed the expansion of the seam is set as a line contact. Therefore, even if there is some difference in the transfer speed between the forced discharge transfer device 35 and the pair of fabric part forced transfer devices 3L, 3R, the line contact portion Sliding absorbs the speed difference without exerting excessive force on the clothes. In addition, the dual-purpose drive motor 20 can simplify the structure of the drive system as a whole of the device.

Furthermore, as shown in this embodiment, the circular cross-sectional endless belts 35L, 35R are wound around two pulleys 37a, 37b located at the start of the forced discharge and transfer of the garments whose seams have been expanded, and are received from the drive motor 20. Between the pulley 37c of driving force and the idler pulley 37d contacting the outer circumference of the circular cross-section belt 35L, 35R, these pulleys 37a-37d are used to move from the second wheel according to the detection action of the detector 40. When the state is switched to the first state and when the state is switched from the first state to the second state, it is supported by a link mechanism 42 that performs a bending action to prevent the circular cross-section endless belts 35L, 35R from detaching, Therefore, it is possible to avoid the occurrence of failures such as the detachment of the circular cross-section endless belts 35L and 35R from the pulleys 7a to 37d, so that they can be used without maintenance.

Furthermore, in this embodiment, in order to gradually increase the opposing pitch of the end portions of the left and right pair of cloth portion forced feeding devices 3L, 3R in the feeding direction, the pair of cloth portion forced feeding devices 3L, 3R can be arranged around The shaft (guide pin) near the center of the forced transfer path is fixed by rotation, but in addition to this, for example, the above-mentioned shaft can be arranged at the beginning or the beginning of the forced feeding path of the forced feeding device 3L, 3R of the cloth part. Closer to the near side of the transfer direction. However, when the above-mentioned shaft is arranged near the center of the forced feeding path as in the present embodiment, the axis rotation accompanying the forced feeding device 3L, 3R of the cloth part can be reduced compared with the case of other configurations. The rate of change of the opposing spacing can improve the adaptability of the expansion function to the degree of shrinkage of the seam.

In addition, in the above-mentioned embodiment, it has been described that the conveying path of the cloth part using the pair of left and right cloth part forced feeding devices 3L, 3R is formed horizontally or substantially horizontally, but the conveying path of the cloth part may be vertically formed. It may be formed straight or substantially vertically, or it may be formed in a state inclined in the up-and-down direction.
