The spindle 152 is installed in the first slider 151 that can be moved left and right along the rail 124, the first driven roller 153 is moved in the first cam groove 142 in a predetermined section Go inward and outward. These spindles 152 are arranged to face each other at predetermined intervals on both sides of the same line.

As can be seen in Figure 8 the straw double wrinkle forming apparatus 100 according to the present invention is provided with a wrinkle forming dice (170). This wrinkle forming dice 170 is substantially square and is arranged long. This is to allow the crease line 13 to be formed on the surface of the straw 10 by engaging with the crimping spiral 154 of the spindle 152. The spindle 152 is arranged to have a sufficient length so that the spindle 152 can be engaged several times. Good to do. This wrinkle forming die 170 will be described in more detail later. Of course, the wrinkle forming dice 170 should be installed at positions corresponding to the wrinkle forming spiral 154 in the state in which the spindle 152 is sufficiently inserted into the straw 10. In order to do so, they are provided to be offset from each other at a predetermined point on the circulating clamper 122.

Straw double wrinkle forming apparatus 100 according to the present invention is provided with a mandrel mechanism (160). The mandrel mechanism 160 is arranged on the same center line as the spindle 152 and has a hollow shape to allow passage of the spindle 152 and the mandrel 162 is a spring 163. The second driven roller 164 installed on the second slider 161 and the second slider 161 and installed on the second slider 161 so as to be movable sideways along the rail 124 is coupled to the second cam groove 144. ). The mandrel mechanism 160 pushes the mandrel 162 inwards according to the degree of bending of the second cam groove 144 so that the mandrel 162 pushes the straw 10 therein, so that the wrinkles 12 Allow it to be folded. The mandrel mechanism 160 is disposed on each of the flat plate cams 140 on both sides, that is, a pair face each other at a predetermined interval.

It is important here that the mandrel 162 is configured to pass through the spindle 152 in a state where it is arranged in line with the spindle 152 described above. Only then, even if the spindle 152 and the mandrel 162 are installed on the same side with respect to the straw 10, wrinkle formation is possible.

That is, when the motor 136 is driven, the power is transmitted to the sprocket 132 on one side via the speed reducer 138 so that the sprocket 132 is rotated and the sprocket 132 on the other side through the chain 134 by the power. Passed to the four corners of the sprocket 132 are all rotated. Accordingly, the chains 134 on both sides of each of the two front and rear sprockets 132 are in orbital motion, and the sewing machine 120 connected to the chains 134 on both sides is also in orbital motion along the closed surface. .

In this state, when the straw 10 as shown in FIG. 1 is supplied to the clamper 122 through the hopper 110 in the position II of FIG. 5, the clamper 122 bites and moves the straw 10, and At the same time, the spindle mechanism 150 and the mandrel mechanism 160 disposed on both sides thereof are also arranged in line with the clamper 122 and move together.

Ride and move inwards. Accordingly, the first slider 151 also moves inward while pushing the spindle 152 inward. Accordingly, the two opposing spindles 152 on both sides are inserted through the holes of the mandrel 162 arranged on the same center line and into the straw 10 bited by the clamper 122. When the spindle 152 is fully inserted and further advanced, the spindle 152 is rotated while the spindle 152 is rotated by the thread of the die 170 placed thereon near the crimping spiral 154 of the spindle 152. The wrinkled lines 13 are formed in two places at predetermined intervals on the surface.

In further advance in that state, the first driven roller 153 moves outward by riding the first cam groove 142 to move the first slider 151 outward along the rail 124. Accordingly, the spindle 152 moves in the direction of exiting the straw 10, and at the same time, the second driven roller 164 moves inward by riding the second cam groove 144, whereby the second slider 161 and the The mandrel 162 coupled to each compresses the straw 10 while moving inward. As a result, the wrinkles 12 are folded, so that the wrinkles 12 are formed in duplicate at predetermined intervals on the surface of the straw 10. When the corrugation 12 is completely formed, the spindle 152 is completely removed from the straw 10, and is in a state of being bitten only by the clamper 122, and in this state, the straw is a release mechanism installed on the movement path of the straw 10. Departing from 10), the straw 10a having double wrinkles is completed. By repeating this process it is possible to make a straw (10a) is formed in a continuous double wrinkles.

10 is a view showing the arrangement of the spindle and the die for forming a wrinkle line.

That is, when the spindle 152 passes sufficiently under the die 170 in a state where the spindle 152 is sufficiently inserted into the straw 10, the straw (between the crimping spiral 154 of the spindle 152 and the thread 172 of the die 170) One side of 10 is snapped, and when the spindle 152 is advanced in that state, the spindle 152 is rotated so that a wrinkled line 13 is formed on the surface of the straw 10.

11 is a sectional view showing the spindle mechanism.

As shown in FIG. 11, the spindle mechanism 150 rotates to the first slider 151 and the first driven roller 153 and the first slider 151 installed on the first slider 151 and the first slider 151 so as to be movable along the rail. The spindle 152 is installed as possible. Of course, a crimping spiral 154 is formed near the end of the spindle 152, and is held by the collet chuck 155 and does not move in the longitudinal direction, and is supported by the bearing 156. When the first driven roller 153 moves in the state as shown, the first slider 151 and the spindle 152 move together.

12 is a sectional view showing the mandrel mechanism, and FIG. 13 is a right side view of the mandrel mechanism.

As shown in FIG. 12, the mandrel mechanism 160 is coupled to the hollow mandrel 162 through which the spindle 152 passes and the second cam groove 144 and moves along the path thereof.
