And the rotating piece 149 is positioned in the ready state from the rear side of the rotating piece 121 by the backward movement of the rotating cylinder 141. [

The present invention in the initial state as described above enables the sleeve 164 to be formed or the collar 174 to be selectively sewn.

First, the operation for sewing the sleeve 164 is described as follows.

In order to form the sleeve 164, the sleeve 163 is inserted into the sleeve molding plate 161 formed in two layers as shown in FIG.

The sewing passage 162 on one side of the sleeve molding plate 161 is positioned on the lower side of the sewing needle 104 of the sewing machine 101 and the cutter 105 as shown in Fig. The plurality of pressure-sensitive bearing units 103 coupled to the presser foot 102 are pressed against the surface of the sleeve forming plate 161.

After the surface of the sleeve molding plate 161 is pressed by the pressing bearings 103 of the presser foot 102 as described above and then the sleeve button of the controllable box 112 mounted on the upper side of the sewing machine 101 is pressed, The forward and backward cylinders 136 coupled to the fixing pieces 133 of the first and second pistons 132 move to advance the piston 137.

The movement piece 135 coupled to the piston 137 is advanced together with the movement table 134 and the support table 128 seated on the movement table 134 is also moved forward by the advance of the piston 137, The rotating plate 121 coupled to the lower end of the rotating shaft 122 of the rotating shaft 122 is moved forward as well and is brought into close contact with one side of the waiting sleeve forming plate 161 as shown in FIG.

When the motor 127 mounted on the support base 128 is driven by the instruction of the control box 112 and the drive shaft 126 is driven And the driving pulley 125 coupled to the driving shaft 126 is also driven to rotate the belt 124 to rotate the interlocking pulley 123 interlocked with the belt 124. As a result, So that the rotating plate 121 is rotated.

6 to the solid line position by the rotation of the rotary plate 121 and the rotary plate 121 is positioned at the corner of the sleeve molding plate 161 The sleeve forming plate 161 rotates at the virtual line position at the solid line position in FIG. 7, and the direction can be switched.

Of course, as described above, the sewing work by the sewing needle 104 and the cutting operation by the cutter 105 are simultaneously performed in the sewing passage 162 while the sleeve forming plate 161 is in motion.

That is, the sewing needle 104 performs sewing while performing the external sound quality by a conventional sewing function of the sewing machine 101.

The cutting function of the cutter 105 is also such that the operation of the cutting cylinder 109 mounted on the support plate 110 of the sewing machine 101 causes the piston 108 and the connecting piece 107 to reciprocate, The cutter 105 connected to the operation shaft 106 can reciprocate upward and downward while shaking the operation shaft 106 while moving, thereby cutting the sleeve stitch 163.

8, the direction of the sleeve forming plate 161 is finally switched to complete the sewing and cutting as shown in Fig. 8 by the rotation of the rotating plate 121. Then, the sleeve forming plate 161 is moved to the solid line position The sewing needle 104 of the sewing machine 101 and the cutter 105 and the presser foot 102 ascend upward and at the same time the forward and backward cylinders 136 of the moving table 134 are operated, So that the support table 128 and the rotary plate 121 are returned to their original positions.

At the same time that the rotary plate 121 is returned to its original position, the take-out cylinder 155 is operated by the instruction of the control box 112 to move the piston 154 backward.

The connecting member 153 connected to the end portion of the piston 154 is moved backward in the moving hole 138 of the pedestal 131 by the backward movement of the piston 154 to transfer the conveying plate 152, The blow-out pieces 151 connected to the plate 152 can strike one side of the sleeve forming plate 161 to be taken out to the virtual line position at the solid line position in Fig.

15, the sleeves 164 in which the sewing lines 181 and the cutting lines 182 are sewn-formed can be obtained by removing the sleeve stitches 163 in the sleeve molding plate 161 taken out.

The operation for sewing the collar 174 will now be described.

In order to form the collar 174, the color stitching member 173 is inserted into a two-layered color forming plate 171 as shown in FIG.

The sewing passage 172 on one side of the collar forming plate 171 is positioned on the sewing needle 104 of the sewing machine 101 and the lower portion of the cutter 105 as shown in Fig. A plurality of pressure-sensitive bearing units 103 coupled to the presser foot 102 are pressed against the surface of the collar-shaped plate 171.

The surface of the collar forming plate 171 is pressed by the pressing bearings 103 of the presser foot 102 and then the color button of the control lorry box 112 mounted on the upper side of the sewing machine 101 is pressed, The forward and backward cylinders 136 coupled to the fixing pieces 133 of the first and second pistons 132 move to advance the piston 137.

The movement piece 135 coupled to the piston 137 is advanced together with the movement table 134 and the support table 128 seated on the movement table 134 is also moved forward by the advance of the piston 137, The rotary plate 121 coupled to the lower end of the rotary shaft 122 of the rotary shaft 122 is moved forward as well and is brought into close contact with one side of the collar forming plate 171 waiting as shown in FIG.

When the motor 127 mounted on the support table 128 is driven by the instruction of the control box 112 and the drive shaft 126 is rotated And the driving pulley 125 coupled to the driving shaft 126 is also driven to rotate the belt 124 to rotate the interlocking pulley 123 interlocked with the belt 124. As a result, So that the rotating plate 121 is rotated.

Therefore, the color plate 171 can be linearly moved to the solid line position in FIG. 12 by the rotation of the rotation plate 121, and when the rotation plate 121 is positioned at the corner of the color plate 171 The color forming plate 171 must be forcibly rotated corresponding to the inclined sewing passage 172 formed in the color forming plate 171 by the sensing action of the detection sensor 111. [

At this time, the rotation cylinder 141 coupled to the bracket 113 on the rear side of the sewing machine 101 is operated by the instruction of the control box 112 receiving the signal of the detection sensor 111, And the connecting piece 143 connected to the piston 142 by the advancement of the piston 142 transmits the force to the rotating body 145 through the hinge shaft 144. The rotating body 145 rotates the bearings 146 As shown in Fig. 13, on the guide rails 114 together with the guide rails 114a and 114b.

The engaging piece 148 of the engaging body 147 coupled to the bottom of the rotating body 145 also rotates due to the movement of the rotating body 145 and the rotating piece 149 13, the collar forming plate 171, which has reached the virtual line position in FIG. 13, can be rotated to the solid line position.

Of course, as described above, in the sewing passage 172 during the movement of the collar forming plate 171, the sewing operation by the sewing needle 104 and the cutting operation by the cutter 105 are simultaneously performed.

The cutting function of the cutter 105 is also such that the operation of the cutting cylinder 109 mounted on the support plate 110 of the sewing machine 101 causes the piston 108 and the connecting piece 107 to reciprocate, It is possible to cut the color sewing material 173 while the cutter 105 connected to the operation shaft 106 reciprocates upward and downward by shaking the operation shaft 106 while moving.

13, the direction of the color plate 171 is finally switched to complete the sewing and cutting as shown in FIG. 13 by the rotation of the rotary plate 121. Then, The sewing needle 104 of the sewing machine 101 and the cutter 105 and the presser foot 102 are lifted upward and at the same time the forward and backward cylinders 136 of the moving table 134 are actuated By moving the piston 137 backward, the support base 128 and the rotary plate 121 are returned to their original positions.

The connecting member 153 connected to the end portion of the piston 154 is moved backward in the moving hole 138 of the pedestal 131 by the backward movement of the piston 154 to transfer the conveying plate 152, The blow-out pieces 151 connected to the plate 152 can strike one side of the sleeve forming plate 161 to be taken out to the solid line position at the virtual line position in Fig.

16, the collar 174, in which the sewing line 181 and the cutting line 182 are sewn, can be obtained by pulling out the color sewing material 173 in the taken-out color forming plate 171. [

According to the present invention as described above, the sewing and cutting operation can be performed while automatically performing the operation of moving the sleeve forming plate 161 and the color forming plate 171 and the turning operation of the color forming plate 171 So that the molding operation of the sleeve 164 and the collar 174 can be performed accurately and quickly, and thus the productivity can be doubled by the improved working efficiency.
