Before and after the chain gear 15b of the rotating shaft 13c, the spur gear 14c with the number of teeth which is substantially smaller than the belt pulley 10d is inserted.

The belt pulley 10d of the rotating shaft 13c is a connecting means for driving the auxiliary feeding roller 18a on the front side of the side feeding device 7a, and is formed on the rotating shaft 13d on which the auxiliary feeding roller 18a is built. It is connected to the belt pulley (10e) and the spring belt (19). This is because the auxiliary feed roller (18a) is required to adjust the interval back and forth to continue to deliver power even in the state of the gap adjustment.

Front and rear interval adjustment of the auxiliary feed roller (18a) is engaged by engaging the rack 37 and the pinion (38) to rotate the adjustment lever 39 to make the gap adjustment (see side view of the operating state of Figure 4).

And the spur gear 14c on the said rotating shaft 13c is connected with the spur gear 14d by which power is transmitted or interrupted while folding a certain angle upward. The rotating shaft 13e, into which the spur gear 14d is inserted, is installed on the rotating bracket 20. At one end of the rotating bracket 20, a blotting roller 21 which presses and pulls a blanket with the side take-out roller 16 Is installed. The squeeze roller 21 is also connected by the rotation shaft 13e, the chain gears 15c, 15d, 15e, and 15f and the auxiliary rotation shaft 13f so as to be rotatable.

In addition, the pivot bracket 22 is connected by a connecting rod 23a in cooperation with the reciprocating device 8 to guide the quilt from the top to guide the zigzag. The guide rollers 24 are installed on the connecting rods 23a up and down, and the guide rollers 24a are provided on the guide rollers 24 with a reciprocating rod 25a for reciprocating left and right by the guide of the reciprocating device 8. One side end of the reciprocating section 25a has a (U) shape to easily connect the reciprocating device 8 when the power is transmitted and cut off, and on the opposite side, a narrowing roller 26 is provided at the bottom of the connecting lever 27. It is attached to the left and right to rotate.

The rotation bracket 20 is connected to the operation pedal 34 of one side of the body by connecting the rod 33 is attached to one side, it is installed to be rotatable by the operation of the operation pedal 34.

Next, the detailed configuration of the reciprocating device 8 for reciprocating left and right and zipping the quilt in zigzag will be examined in cooperation with the intervening roller 26 placed between the intersecting sides of the side feeder 7a.

3 is a perspective view showing the configuration of the reciprocating device 8.

The chain gear 15g is inserted into the motor 5b installed on one side of the frame 2, and the chain gear 15g is inserted into the chain 17b by the chain 17b on the connecting pivot 13g of the reciprocating device 8. Connected to 15h.

At the other end of the rotating shaft 13g, a bevel gear 28a is inserted into the bevel gear 28b on the rotating shaft 13h vertically inserted by the bevel gear 28a. A circular cam 29 is installed at the upper end of the rotation shaft 13h, and the circular cam 29 is provided with an adjustment piece 31 which is eccentric in a predetermined width and can arbitrarily adjust the eccentric distance by the adjustment bolt 930.

The adjusting piece 31 is connected to a reciprocating lever 32 reciprocating from side to side in the rotation of the circular cam 29. The other end of the reciprocating lever 32 is configured such that the (U) type reciprocating section 25a of the sandwiching section 22 described above is connectable.

In addition, one end of the reciprocating lever 32 is connected to another reciprocating section 25b by a connecting section 23b connected to the lower end of the base 3.

A coupling piece 35 is formed at the other end of the reciprocating section 25b so as to intervene in the long hole 3a on the base 3, thereby screwing the reciprocating plate 36 at the top.

In addition, the rear side of the handling roller (12) was formed in the form of a screw (40) as a protrusion to spread the wrinkles when feeding the Evil, the rear side of the handling roller (12) is also connected to the auxiliary feed roller (18b) in the rear It is installed by rotation.

Unexplained reference numeral 41 in the drawings will be described in detail below the operation method and the effect of the operation method and the resulting configuration of the present invention configured as described above.

Figure 4 is a side view schematically showing the operating state of the present invention as a quilt sewing sewing (a) is connected to both ends of the sewing ring to form a ring (2) one side of the support opening interval 41 to disassemble the base (2 After inserting into the upper part of the support opening (41) and then restoring and restoring the sewing machine (drives the sewing machine to drive the sewing machine (40), prior to operating the sewing machine, the quilt fitted to the base (2) first (a) This necessitates the necessity of winding the quilt, ie, it is natural that the quilt (a) must be wound in a tight tension in order to smoothly handle the quilt (a) by using the post-transmission rollers (16, 12). Do.

To this end, in the present invention, the auxiliary feed roller (18a) is installed on the side of the base (2) to adjust the front and rear spacing, and the specific method of adjusting the rack (37) by rotating the control lever 39 connected to the pinion (38). Of course, as the reciprocating back and forth movement of the auxiliary feed roller (18a) connected to the rack 37 is a certain width interval adjustment is made on the side of the expectation (2) can be wound up comfortably (a).

When the tensioning of the futon (a) is completed, sewing is started after turning on both motors (5a, 5b). The futon (a) is turned up and down (2) up and down by the rotation of the forward and backward handling rollers (16, 12). It is fed to the sewing machine (4) while rotating continuously, the spiral protrusion 40 of the handle roller 12, which is the rear side, serves to straighten the wrinkles of the quilt (a) to be fed, and the handling roller The squeeze roller 21 engaged with (16) rotates the quilt (a), so that the worker can reduce the manpower and improve work efficiency by eliminating the rapid hassle by hand. .

And another effect of the present invention is to install a reciprocating device (8) that can automatically feed the quilt in zigzag when sewing the sewing line zigzag on the quilt (a), the operation and effect of this in more detail ; When the circular cam 29 on one side of the base 3 is rotated by the motor 5b, the reciprocating lever 32 eccentrically installed on the circular cam 29 causes the reciprocating motion to the left and right, and the reciprocating lever 32 Reciprocating plate (25a, 25b) connected to the upper and lower sides of the reciprocating movement to the left and right, the reciprocating plate (26) and the fixed reciprocating plate (26) connected to the end of the reciprocating roller (26) connected to one end of the upper reciprocating section (25a) 36) is reciprocated from side to side in the state of holding the blanket (a) up and down, and the blanket (a) is squeezed between the handling roller (16) and the velcro roller (21) on the side and fed to the front side and at the same time. The sewing line sewn by the sewing machine 4 to be reciprocated is naturally sewed in a zigzag.

In the operation of the reciprocating device 8, the random reciprocating distance can be arbitrarily changed by adjusting the eccentric distance of the circular cam 29 of the adjusting piece 31 by adjusting the adjusting bolt 30.

And when the sewing of the duvet (a) is completed in one line, the sewing position of the duvet (a) should be changed. In this case, the side of the handling roller roller (16) and the presser roller (21) spaced from the squeezing rotation are separated by the duvet (a). Since the transfer operation is possible, in this case, the crushing roller 20 in which the blotting roller 21 is installed can be rotated at an appropriate angle to separate the blotting roller 21, and the rotation of the rotation bracket 20 is the operation of one side of the gas. When the pedal 34 is operated, the rotation bracket 20 is angularly moved by several rods 33. If the blanket (a) is in a tightly wound state, the auxiliary feed roller (18a) on the side of the base (3) may be slightly retracted to reduce the tension. At this time, when the control lever 39 on one side of the gas is properly rotated, the pinion 38 at the end is rotated at the same time so that the rack 37 meshed with the pinion 38 performs the forward and backward movement so that the rack 37 is fixed with the rack 37. The support of the auxiliary feed roller (18a) is to perform the back and forth movement to adjust the interval of the auxiliary feed roller (18a).

When the quilt and the tension state are released, the operator transfers the quilt (a) on the left and right width (left and right width of the sewing line) on the expectation (3) and then adjusts the lever when resuming the sewing work again. And while operating the operation pedal (34) to tension the futon (a) and at the same time to perform the sewing operation continuously in the pressed state.

As described above, the feeding device of the quilting quilter provided in the present invention smoothly performs continuous feeding of the quilting sewing machine to maximize the work efficiency and minimize the waste of manpower, as well as zigzag the sewing line. When sewing as a co-operator, the reciprocating device can be operated at the same time as the left and right reciprocating movements, so it is a useful design that can completely solve the difficulty of the existing work.

In the following appended claims of utility model registration, the technical configuration to be protected in the present invention will be mentioned, but the similarly changed aspects of simply changing the position of each device or changing the power transmission configuration are also technical scope of the present invention. Will be included in.
