Description

[Detailed Description of the Invention] The present invention relates to a sewing plant that continuously manufactures quilted and hemmed futons of fixed length from cloth and cotton as materials.

The sewing process for making futons requires a lot of work, such as layering cloth and cotton and feeding it into a multi-head sewing machine, hemming the overlapped cloth and cotton that has been hung on the machine, and cutting it to a standard length. However, the present invention relates to a futon sewing plant that cleverly automates and serializes the futon manufacturing process, thereby eliminating human labor and making it possible to continuously manufacture quilted futons of fixed length at low cost.

The present invention will be described below with reference to drawings showing embodiments thereof.

Outer fabric wrapping roll 1, wrapping roll 2 of urethane foam sliced into thin plates as filling, wrapping roll 3 of cotton stretched into thin plates as other filling, and back fabric wrapping roll 2. 4 is rotatably supported on a support 6° 7.8.9 so that by pulling it from the front, they become a stacked material 5 and are sequentially fed out forward (however, the cotton wrapped roll 3 is In order to prevent the winding roll 3 from being pulled and cut, upper and lower rollers are provided vertically on the support 8 so that the winding roll 3 is always resting on the lining cloth and thin urethane foam material below. (The shaft is pivoted in such a manner that only movement in the front and back direction is suppressed through the long shaft hole 30.)
At the same time, the superimposed material 5 of these cloths and battings are sequentially made.
An automatic fabric feeder 14 is equipped with power rotating rolls 11, 12, and 13 whose rotational speeds can be freely adjusted to run the lower part of the needle 31 of the multi-head sewing machine 10, and it swings the fabric appropriately in the left and right directions. As shown in FIG. 2, the powered rotating roll 1 is provided with wheels 33 at the bottom of its frame 32 so that it rolls from side to side on rails 34 for repeatability.
Similarly, the power rotating roll 11°12.13 has a structure in which the frame 32 is connected to a shaft 36 that reciprocates in the left-right direction in response to the rotation of a cam 35 that is interlocked with the rotation of 1.12.13.
It is combined into a multi-head sewing machine 10 that operates in conjunction with the rotation of the sewing machine.

Next, there is an effect of suppressing and stopping the swinging of the quilted fabric and cotton stack 5 sequentially sent out from the multi-head sewing machine 10, and an effect of buffering changes in the running speed of the stack 5. The chain 15.15 is hung slightly loosely in the vertical direction, and the chain 15.15 of the flexible chain wheel device 16.16 is installed on both the left and right sides.
The stack 5 is tensioned by speed-adjustable power rotating rolls 37 and 37' for trimming the left and right edges of the stack 5 through a step roll 17 horizontally engaged between them. The multi-headed sewing machine 10 is followed by a continuous double-sided longitudinal cutting machine 19 that sequentially traverses the both sides using round-blade rotary cutters 18. A tape-like hem 20 from a hem reel 38.38 placed on a hem reel stand 39.39, to be applied successively to the edges parallel to them and in a manner surrounding them both from above and below. . 21, side edge position deviation detectors 41 and 41 that emit a signal when the side edges of the superimposed object 5 come into contact, which should keep the traveling position of the superimposed object 5 constant on a plane, and a side edge position shift detector 41, 41 that outputs a signal when the side edges of the superimposed object 5 come into contact with each other; The stacked material 5 is pinched from both sides by scissor-shaped rotatable rolls 42 and 42 with two rotatable rolls 42 and 42 on each side (rotatable to prevent the running of the stacked material 5 from being stopped). After moving the stacked object 5 to a position where the side edge thereof no longer contacts the detector 41.41, the two rotatable rolls 42.42 stop picking up the stacked object 5 and return it to its original position. 43.4 Stacked object moving device that automatically returns to
A hem cloth sewing machine 22.2 is provided with a superimposed object position control device 23 consisting of 3 and 3 and has a mutually symmetrical mechanism.
2 facing each other and a hem cloth 20.2 on each side edge of the stacked object 5.
The continuous double-sided hemming machine 19 is followed by a continuous hemming machine 24, which is arranged such that each needle 44 of the sewing machines 22, 22 is located above the attachment point 20.

In addition, the reference numeral 45 in the drawings indicates a power rotating roll 46 for making the stacked material 5 run on the continuous edger 24.
, 46 are rotatable rolls that protrude inwardly and upwardly from both sides of the continuous edging machine 24 and support the central part of the traveling stacked material 5, and 47 are rotatable rolls that slightly support the center portion of the traveling stacked material 5.
A roll whose center part curves slightly upward in an arch shape (to reduce the running friction of the stacked object 5) (In some cases, flexible tubular bodies such as flexible tubes are rotatably sheathed) are shown.

Next, a chain 25.25 is further hung in the vertical direction,
Flexible chain wheel device installed on both left and right sides 26.26
It rotates in contact with the traveling stacked object 5 via a step roll 27 horizontally attached between the chains 25 and 25 of the chain 25, and is based on a signal from a pulse oscillator 48 that is transmitted in accordance with the traveling of the stacked object 5. A meter running control device 53 that temporarily stops the running of the stacked object 5 caused by the rotation of the power rotation roll 49 every time the stacked object reaches a certain distance; A pressing rod plate 50 suspended horizontally on the running path of the stacked object 5 is lowered from above to hold the stacked object 5 stationary in a pressed state, and a rotary round blade cutter 51 is run along the pressing rod plate 50 to remove the stacked object 5. The continuous hemming machine 24 is followed by a fixed length cutting machine 29 equipped with a stacked object crossing device 28 that traverses the shaped object 5 and pulls the pressing rod plate 50 upward again after the traversing operation. This is a continuous sewing plant for futons.

In the continuous sewing plant for fixed-length futons as described above, cam 3
5 to swing the frame 32 of the automatic fabric feeder 14 in the left-right direction on the rail 34, and rotate the power rotating rolls 11, 12, and 13 at appropriate speeds, thereby forming the outer fabric wrapping roll 1 and the urethane foam. winding roll 2
, the respective fabrics and battings from the cotton wrapping roll 3 and the lining fabric wrapping roll 4 are made to run under the needle 31 of the multi-head sewing machine 10 while being oscillated in the left-right direction at an appropriate constant amplitude as a superimposed material 5. The superimposed material 5 sent out from the multi-head sewing machine 10 is automatically quilted into a wavy pattern with a constant amplitude as shown at the right end of FIG. 2 without any manual effort. be done.

The quilted stack 5 is then tensioned by the powered rotating rolls 37, 37' of the continuous double-sided longitudinal cutter 19 and trimmed on both sides by the round-blade rotating cutters 18, 18. Between the vertical cutting machine 19 and the multi-head sewing machine 10, a step roll 17 is connected between the chains 15 and 15, which are slightly loosely chained vertically on each of the flexible chain wheel devices 16 and 16. As shown by the chain line in FIG. 1, even if there is a slight difference in speed between the processing speed of the vertical cutting machine 19 and the delivery speed of the stacked material 5 from the multi-head sewing machine 10, It can be absorbed and buffered by the vertical movement of the stepped roll 17, so that there is no inconvenience in communication between the vertical cutting machine 19 and the multi-head sewing machine 10, and furthermore, the slack can be hung with a chain. The bending of the chain effectively buffers and stops the swinging of the quilted stacked material 5 caused by the swinging of the frame 32 of the automatic cloth feeder 14, and the cutter 18 .18 will have a significant effect on stabilizing the work of trimming and aligning both sides of the stacked object 5.

Further, the stacked material 5 from the both-side longitudinal cutting machine 19 is run on a continuous hemming machine 24 under the action of a power rotating roll 45, and the hem cloth is sequentially attached to both side edges by the hem cloth attaching device 21 as described above. 20, 20 are sewn continuously on both side edges by hem cloth sewing machines 22, 22, and are driven via step rolls 27 hooked between the chains of a universal chain wheel device 26, 26. The paper is pulled by a powered rotary roll 49 and runs over the following standard length cutter 29, and is activated when the signal from the pulse transmitter 48 notifies that the drive has reached a predetermined distance as described above. The futon 52 with a wavy quilting pattern is traversed to a predetermined length by the action of the meter travel control device 27 and the superimposed object crossing device 28 and sent out from the standard length cutting machine 29.
When the running of the stacked object is stopped by the operation of the running control device 27, the step roll 27 is lowered and the stacked object that is continuously fed out from the continuous hemming machine 24 is moved to the flexible chain wheel device 26.26 section. Since it acts to temporarily store the objects 5, there is no problem even if the continuous hemming machine 24 is followed by the regular length cutting machine 29, which should stop running intermittently.

As described above, the quilted and sewn standard-length futon 52 that is sent out one after another from the standard-length cutting machine 29 is then automatically hemmed in the same manner as the continuous hemming machine 24 on the side edges that newly appear due to the above-mentioned crossing operation. The edges are sewn by a machine or by hand, and can easily be made into a complete futon product.

As described above, the present invention is capable of continuously manufacturing quilted and sewn fixed size futons one after another without using any manual labor, so its effect on the mass production of quilted and sewn futons and the gradual reduction of manufacturing costs. Remarkable.
