When the gusset body 7 is disengaged from the carrier pipe 61, the sixth air cylinder 97 is operated to incline the fixing portion 93a of the rodless air cylinder 93, so that the gap between the pair of fingers 99 is increased. It is possible to remove the gusset body 7. That is, the gusseted body 7 having the base end portion sewn into a loop shape can be dropped on the mounting table 100 provided below the middle portion in the longitudinal direction of the main body 11 shown in FIG. 10.

Next, a procedure for sewing the gusseted body 7 in a loop shape by the apparatus having the above-mentioned structure will be described. First, the first cylinder 23 of the transport mechanism 12 is operated to raise the first and second upper rollers 21 and 22, and the strip-shaped gusset body is formed between the lower rollers 16 and 17 which are separated from each other. When 7 is supplied, the operation of the first cylinder 23 is released, and the first and second upper rollers 21, 22 are lowered by the restoring force of the pressing spring 24. As a result, the gusset body 7 is sandwiched by the pair of upper and lower rollers.

When the operation of the first cylinder 23 is completed, the first motor 29 is operated and the second lower roller 17 is rotationally driven. When the second lower roller 17 is rotationally driven, the second upper roller 22 is interlocked via the gear 33.
The rotation of the second upper roller 22 is transmitted to the one-way clutch 35 via the sprocket 34 and the chain 36. The one-way clutch 35 is attached to the support shaft 16a of the first lower roller 16. It spins in the air. Therefore, the gusset body 7 has a second lower roller 17 and a second upper roller.
It will be sandwiched and carried by the la 22.

The gusset body 7 sent out between the pair of second rollers 17 and 22 passes through the guide body 37, is detected by the first sensor 39, and is sent to the moving body 38.
On the moving body 38, a first air parallel hand 48 opens a pair of fingers 49 as shown in FIG. 3 and stands by in a lowered state. Therefore, the tip of the gusset body 7 sent from the rollers 17 and 22 enters between the pair of fingers 49. Further, the feed amount of the gusset body 7 is detected by the first sensor 39, and the first motor 29 is stopped when the tip portion thereof enters between the pair of fingers 49.

Next, the pair of fingers 49 of the first air parallel hand 48 are driven in the closing direction to clamp the tip portion of the gusset body 7. Following that, the first high-rotor 4
4 operates to rotate the support link 45 from the lowered position shown by the solid line in FIG. 3 to the raised position shown by the chain line. The revolution of the first air parallel hand 48, which is the rotation of the support link 45 in the ascending direction, is stopped when the rotation of the support link 45 is detected by the third sensor 50b.

Then, the second high rotor 52 provided at the other end of the support link 45 is actuated, and the first air parallel hand 48 is changed from the state shown by the chain line in FIG. 3 to the state shown by the chain line in FIG. Rotate to. The rotation of the first air parallel hand 48 is stopped by the detection by the fifth sensor 50d. The revolution and rotation of the first air parallel hand 48 are performed while the first motor 29 is actuated again and the gusset body 7 is sent out from the transport mechanism 12.

When the revolution and rotation of the first air parallel hand 48 are completed, the gusset body 7 is in a state where its midway portion is in contact with the transport pipe 61 as shown in FIG. Also,
At that time, the fourth air cylinder 84 shown in FIG. 7 operates to rotate the two support pipes 77 in a state parallel to the width direction of the main body 11 and eject compressed air from the ejection holes 77a.

Next, the second motor 65 for driving the above-mentioned transfer pipe 61 is operated to cause the wire 62 to travel. As a result, the support column 58 supporting the transfer pipe 61 travels toward the other end side of the main body 11 shown by the arrow X in FIG. At the same time, the first motor 29 again operates to send out the gusseted body 7 from the transport mechanism 12. As a result, the transport pipe 61 engages with the midway portion of the gusseted body 7 and pulls the gusseted body 7 in a two-ply state. At this time, the electromagnetic brake 26 provided on the support shaft 16a supporting the first lower roller 16 of the transport mechanism 12 operates,
A brake is applied to the rotation of the first lower roller 16. As a result, resistance is imparted to the rotation of the first lower roller 16, so that the pair of first lower rollers 16 and 21 and the second lower rollers 16 and 21 are rotated.
A predetermined tension is applied to the gusset body 7 between the lower and upper rollers 17 and 22. As a result, regardless of whether the gusseted body 7 is easily stretchable or difficult to stretch, the gusseted body 7 can be fed in a state of constant tension, so that the feeding length does not vary.

When the support column 58 supporting the transfer pipe 61 travels in the direction of the arrow X, the metal body 59 provided at the lower end of the support column 58 is attached to the frame body 87 as shown in FIG. 8A. While being adsorbed by 90, the support column 58 is further driven in the direction of the arrow X by the wire 61 in this state, and the gusset body 7 is pulled out by the transport pipe 61 accordingly.

When the rotation speed of the second lower roller 17 due to the driving of the transfer pipe 61 reaches a predetermined rotation speed, which is input from the encoder 27 to the control device 40, the transfer operation is carried out. The second motor 65 that drives the pipe 61 is stopped. In other words, the gusseted body 7 is fed out in a predetermined length (approximately the same length as the outer circumference of the spring unit 3) while applying a predetermined tension.

As described above, when the gusset body 7 is fed out for a predetermined length, the fifth air cylinder 91 is actuated to project the rod 91a thereof, and the center marker 92 is moved to the carrier pipe 61.
Abutting on the portion engaged with (this portion is the leading end on the pull-out side). Then, the fourth high-rotor 89 is activated to move the fifth air cylinder 91 together with the center marker 92.
By rotating, the tip of the gusset body 7, that is, 2
A mark is attached to the central portion in the lengthwise direction when the sheets are folded in a stack.

Further, the first air parallel hand 48 in the state shown by the chain line in FIG. 4 when the first high rotor 44 is activated.
Is revolved downward as shown by the solid line in the figure. As a result, the first cutter 53 provided on the outer surface of one finger 49 of the first air parallel hand 48 is attached to the moving body 3
The gusseted body 7 of two sheets located on 8 is pressed and held.
The portion of the gusset body 7 that is pressed by the first cutter 53 is the base end portion.

Further, the second air cylinder 201 is actuated to operate the pressing body 202 provided at the tip of the rod 201a.
Thus, the first air parallel hand 48 is pressed so as not to rotate upward. In this state, the third air cylinder 54 operates and the second cutter 55 rises, and the base end of the gusset body 7 is cut by the first cutter 53.

When the base end portion of the gusset body 7 is completely cut off in this manner, the rod 54a of the third air cylinder 54 is driven in the retracted direction to lower the second cutter 55, and at the same time, the transport mechanism. The first motor 29 of 12 rotates in the reverse direction, and the gusset body 7 is retracted until the tip of the gusset body 7 located on the side of the transport mechanism 12 is located behind the first sensor 38. Further, the third high-rotor 74 is actuated to operate the presser bar 7
5 is laid down from the standing state, and the base end of the gusset body 7 located on the moving body 38 is pressed.

Next, the third motor 71 shown in FIG. 11 is operated to cause the timing belt 67 to run endlessly, thereby moving the moving body 38 toward the sewing machine base 72 as shown by the chain line in FIG. . Then, the sewing machine 73 operates to sew the base end portion of the gusseted body 7, whereby the strip-shaped gusseted body 7 is sewn in a loop shape. At this time, since the base end portion of the gusset body 7 is pressed and held by the first cutter 53 and the pressing rod 75, even if the moving body 38 moves with the tip end engaged with the transport pipe 61. , The above gusset body 7
The base end of the above does not move on the moving body 38.
That is, it is possible to reliably sew a predetermined portion of the base end portion of the gusset body 7.

When the sewing of the base end portion of the gusset body 7 is completed in this way, the third high-rotor 74 operates in the direction opposite to the above to raise the presser bar 75, and at the same time, the third moth. -The rotor 71 rotates in the reverse direction to return the movable body 38 onto the fixed body 41.

Further, the rodless air cylinder 93 operates to drive the second air parallel hand 98, and the pair of fingers 99 of the finger 99 cuts the cutout portion 10 of the carrier pipe 61 of the gusset body 7.
The part engaged with 1 is clamped and moved, and the part is removed from the above-mentioned transport pipe 61. Then, the fourth air cylinder 8
The fourth rod 84a is driven in the retracted direction, and as shown by the solid line in FIG. 7, the support pipe 77 in a state parallel to the width direction of the main body 11 is rotated in the orthogonal direction. That is, the supporting state of the middle portion of the gusset body 7 by the two support pipes 77 is released.

In this state, the sixth air cylinder 97 is operated, and the second air parallel hand 98 is tilted together with the rodless air cylinder 93 as shown by the chain line in FIG. When the pair of fingers 99 of the air parallel hand 98 are opened, the gusseted body 7 sewn in a loop shape is dropped onto the mounting table 100 below the middle part of the main body 11. After that, the first air parallel hand 48 and the second air parallel hand 98 are returned to the initial state, thereby completing one step.

In this way, the tip end of the belt-shaped gusset body 7 is sandwiched by the first air parallel hand 48, the conveying pipe 61 is engaged in the middle portion, the driving of the conveying pipe 61 and the conveying mechanism 12 are performed. By cooperating with the feeding by, the gusseted body 7 can be automatically fed by a predetermined length in a state where two gusseted bodies 7 are stacked. And sent out in a predetermined length,
The loop-shaped gusset body 7 was formed by sewing the base end portions of the two-layered gusset body 7 with the sewing machine 73. Therefore, it is possible to automatically cut the gusseted body 7 to a predetermined length or loop-like suture, which has hitherto relied on manual work.

In order to sew the loop-shaped gusset body 7 to the peripheral portion of the mirror body 6, first, the sewn base end side of the gusset body 7 is sewn to the mirror body 6. Sew on one end side, and then from both sides to the other end side. At that time, a mark is marked by a center marker 92 at the longitudinal center of the gusset body 7. Therefore, if the degree of pulling of the gusset body 7 is adjusted by aligning the mark with the center of the other end side of the body 6, the gusset body 7 can be pulled uniformly over the entire circumference of the body 6. It can be sewn in the state. Moreover, gusset body 7
When the quality label of the mattress device 1 is sewn on, since the mark is provided at the center, the positioning can be performed easily and surely.

On the other hand, the transport mechanism 12 has a gusset body 7
An electromagnetic blade for imparting a certain tension to the gusset body 7 on the support shaft 16a of the first lower roller 16 when carrying the
The key 26 is provided. Therefore, even if the gusseted body 7 is a stretchable fabric or a stretchable fabric, the transport mechanism 12 can feed the gusseted body 7 in a constant length. That is, even if the gusseted body 7 is made of a stretchable material, the gusseted body 7 can be formed into a loop shape having a constant length without causing variations in length. Therefore, when the gusset body 7 is sewn to the mirror body 6, it is not necessary to change the tension applied to each gusset body 7, so that the sewing work of the body 6 and the gusset body 7 is performed. Can be performed reliably and easily.

As described above, according to the present invention, the leading end of the belt-shaped gusset body fed by the transport mechanism is clamped by the chuck mechanism that is capable of revolving and rotating, and is placed in the middle of this gusset body. The pull-out mechanism is engaged, the transport mechanism and the pull-out mechanism are made to cooperate with each other, and
The sheets were pulled out in a stacked state, cut by a cutting mechanism with a predetermined length, and the ends cut by the sewing means were sewn to form a loop.

Therefore, the work of sewing a belt-shaped gusset body into a loop shape, which has been conventionally performed manually, can be automated, so that the workability can be improved.
Further, since the belt-shaped gusset body is automatically fed by the transport mechanism, there is no possibility that the feed amount varies and the loop size of the gusset body is not constant.
