[Industrial application fields]
TECHNICAL FIELD The present invention relates to a finishing method for finishing a beautiful corrugated sheet by attaching a number of heels in the length direction to the skirt of a sewn curtain having heels in the length direction on the top, and a finishing apparatus for use in the finishing. Is.
[0002]
[Prior art]
There is already a method of forming, for example, a corrugated cross section in accordance with the heel spacing of the top portion over the entire length of the sewn curtain, which is described in Japanese Patent Publication No. 2860763. According to this method, a curtain having one or more stitches is suspended from a top made of a knitted fabric containing a thermoplastic synthetic fiber, and the portion below the top of the top of the curtain is zigzag in cross section. Bend, overheat steam is sprayed onto the curtain while moving in the vertical or horizontal direction of the curtain by at least one of the front and back sides of the curtain, and one of the zigzag shape is bent and fixed to wave the curtain. It is a method of finishing into a plate shape.
[0003]
However, there is still no method for consistently constructing only the skirt part of the curtain having a ridge on the ceiling from the setting of the ridge interval to the operation of attaching the ridge. There are provided an iron head for injecting superheated steam arranged in a plurality of rows in a common support plate shape at a predetermined interval, and an iron cradle arranged in a plurality of rows on another common support plate at the same interval as the iron head. There is a method in which an iron head is pressed after a thermoplastic curtain is set in the apparatus, and a corrugated sheet-shaped wrinkle is formed on the curtain fabric by superheated steam sprayed from the iron head. According to this method, the curtain is extended at another place, and marking is performed at a predetermined interval on the part to be creased, and then the curtain part marked on each of the iron cradles arranged in a large number is arranged. It is necessary to work one by one. Further, the iron cradle is not provided with a stopping means for maintaining the movement of the curtain.
[0004]
[Problems to be solved by the invention]
However, among the above methods, the method of forming a corrugated plate-shaped ridge over the entire length of the curtain can be used only for the skirt, but it is not economical. On the other hand, the skirt part of the curtain is extended, marking is performed at the brazing position at a predetermined interval, and it is carried to a separate brazing machine and prepared by the above-mentioned procedure manually to perform the brazing work. It is very time consuming. In addition, since all the work up to mounting on the brazing machine is done manually, not only a lot of time is required but also the accuracy of the work in each work stage is lacking. For example, the accuracy of the interval when marking the curtain at a predetermined interval, or the place where the marking of the curtain is placed on a certain iron cradle, and the curtain between the markings with the next iron cradle Repeat the work of hanging the curtain loosely in the gap and aligning the marking position with the next iron cradle, but placing the curtain on the iron cradle during this time. There is a problem. If there is a further deviation, it is necessary to correct this, and this is a reverse operation, which is an inefficient method.
[0005]
From the above, as an alternative to a device for applying a corrugated sheet-shaped ridge over the entire length of the curtain, it is possible to accurately attach a corrugated sheet-shaped crease only to the bottom of the curtain. It is necessary to develop a device that can save labor in a series of operations up to the completion of attachment.
[0006]

To do. The rail 4 is fixed to the base 34 of the entire apparatus together with the mounting base 10. The fixed iron cradle 11 may be arranged at the center of the row of the many iron cradles 2 so that the left and right cradles approach the center.
[0014]
An embodiment of the operation of actually wrinkling the skirt of the curtain A by the apparatus 1 of the present invention described above will be described.
[0015]
A large number of iron receiving bases 2 on the rail 4 are moved on the rail 4 (for example, the case of a plurality of irons is shown in FIG. 2). And the iron cradle 2 is maintained in a state where the distance between the iron cradle 2 and the iron cradle 2 is the same as the distance between the edges when the curtain A is widened.
[0016]
Next, the fixing means 21, 22 of the present invention provided in the cradle 2 on the fixed iron cradle 11 and the outermost iron cradle with both ends of the skirt of the curtain extended at the hem. Secure with 23 etc. Thereafter, the curtain A skirt is fixed to the intermediate iron cradle 2 in the same manner.
[0017]
After the curtain A is placed on a large number of iron cradle 2 and is fixed to each iron cradle 2, the pantograph mechanism 5 moves the large number of iron cradles 2 on the rail 4 via the slider 3. Then, the iron cradle 2 is drawn toward the fixed iron cradle 11 while narrowing the interval between the iron cradle 2. At this time, the curtain A placed on the iron cradle 2 also moves to the fixed iron cradle 11 side together with the iron cradle 2, but the curtain A extending between the iron cradle 2 with the movement is adjacent to the iron. It bends and hangs down under its own weight between the cradle 2. The amount of sag increases as the iron cradle 2 approaches the fixed iron cradle 11 side and the interval between the iron cradle 2 is reduced.
[0018]
A large number of iron cradle 2 is gathered to the fixed iron cradle 11 side at a predetermined interval. At this time, the distance between the iron cradle 2 and the distance between the iron heads 7 is the same. Next, the base plate 9 on which a large number of iron heads 7 are fixed is lowered while rotating around the rotation shaft 33 and pressed against the skirt of the curtain A placed on the large number of iron receiving bases 2 at the same time as heating. Steam is spouted out. Since the mating surfaces of the iron head 7 and the iron cradle 2 each have a semicircular cross section or a U-shaped concave or convex shape, the curtain is pressed following this cross sectional shape. Further, the pushing tool 8 provided between the plurality of iron heads 7 enters between the facing iron cradles while descending, and bends and loosens the curtains hanging down with certainty.
[0019]
In addition, as operation | movement which stops a curtain skirt on the ironing stand 2, after the brazed part of the curtain A skirt is mounted in many curtain cradles 2, as shown to Fig.3 (a), a vacuum pump (Not shown) is operated to adsorb the curtain with a desired negative pressure through the tube to the suction hole 21 provided in the iron cradle 2 or, as shown in FIG. 3B, the end of the iron cradle. For example, the curtain hem edge is sandwiched by nail-shaped clasps 22 attached to the roller 15, or the curtain is pierced by the needle 23 provided on the iron cradle as shown in FIG. In either method, the curtain stoppers 21, 22, and 23 are also held on the iron cradle 2 so that the curtain A does not move, and thereafter the curtain cradle 2 moves to the fixed iron cradle 11 side. Has a function of maintaining this holding state. In addition, when the stopper means for the curtain is the clasp 22 or the needle 23, a space corresponding to the shape of the stopper means is provided between the iron cradle and the iron head, or a hole is formed in a portion facing the needle 23 of the iron head. Needless to say, a clearance space for the needle 23 is provided with a clearance.
[0020]
The above is the operation of the apparatus of the present invention. The curtain A hem is extended, and a large number of brazing points are placed on a large number of iron cradles 2 arranged at predetermined intervals easily and reliably. In this state, a large number of iron cradle 2 can be moved to the fixed iron cradle side 11 by one operation by the pantograph mechanism 5. Note that the iron cradle 2 may be moved manually or may be automated using positioning by motor drive or servo control. When automated, a curtain sewing system can be configured in combination with a machine that performs other processes, sharing the data and using the system controller or machine of the present invention from a machine that uses pleat spacing By transferring to the system, it is possible to obtain a system in which the production of curtains is further enhanced, and a more efficient system configuration can be realized. Further, the position of the fixed iron cradle 11 is not limited to the end of a large number of iron cradle 2, and the left and right iron cradle 2 is the center of the many iron cradle 2 and the fixed iron cradle in the center. 11 may be approached.
[0021]
Further, a large number of iron heads 7 are pressed against a large number of iron receiving bases 2 brought to the opposite positions, and superheated steam is sprayed onto the skirt of the curtain A on the iron receiving base 2 so as to have a desired cross-sectional corrugated plate-like shape. Can be formed in accordance with the ridge spacing of the top. Note that the superheated steam injection function may be provided on either the iron cradle 2 or the iron head 7 side. Further, when a large number of iron receiving bases 2 and iron heads 7 are installed and the number of irons is smaller than that, it is sufficient to use only the necessary amount. On the other hand, if there are cases where the number of powers is larger, it may be divided into multiple times.
