Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for cutting a string made of a soft material such as hand-rolled noodles, clay, and plastic, and at the same time holding the cut end.

(Prior Art) Conventionally, cutting with a push-cutting die or a rotary blade provided with cutting blades in opposing positions so as to sandwich the string body in the center within the feeding region of the long continuous string body which is continuously conveyed and supplied. There was a device, but with the string pulled out to the outside of its travel area, and then the pulled out string was clamped,
There was no cutting device that could cut the side that did not require pinching. Therefore, it is difficult to continue the next work unless one end of the remaining cord body is pulled out and held every time the cord body is cut. More specifically, in the burring process in the process of manufacturing hand-rolled noodles, a thick raw material noodle body wound on a tarai (not shown) is passed through a center hole of the noodle guide tube 7 via a roller (not shown). Then, the end of the noodle band is wound around and fixed to one end of the noodle stick 8 by the operator's hand, and then the noodle strip guide tube 7 is moved while moving the two noodle sticks 8 in the direction A. By moving the noodle sticks 8 in the shape of ∞ so as to straddle the noodle sticks 8
When the noodle strips between the noodle stick 8 and the noodle strip guide tube 7 are cut after the crossing is finished, the remaining noodle strips get stuck in the noodle strip guide tube 7 and get stuck. It seems that it is not possible to restart the chipping work without holding the remaining noodle strips by hand, and continuous work cannot be done by simply cutting, so mechanization was not easy. .

The cutting device must be installed outside the ∞-shaped moving area to have the function of pulling the noodle strings out of the ∞-shaped motion area, and at the same time as the cutting or before the cutting, the noodle strings on the remaining side are There was a constraint that the noodle strip guide tube had to be held at one end so that it would not get in, and there was no device that satisfied that constraint.

(Problems to be solved by the device) The technical problem of the present invention is to arrange the noodle strings or the string material outside the feeding area accompanying the movement of the noodle string guide tube 7 and to cut the noodle strings.
The string is hooked and pulled out of the feeding area, and thereafter, the string is cut while holding one end of the string.

(Means for Solving the Problems) In order to solve the above problems, the present invention is a rod in which one end 3a is fixed to a rotary shaft 2 connected to a drive source 1 such as a motor and the other end 3b is bent into an L shape. A movable blade 3 formed of a body, a fixed blade 4 fixed at a position in contact with a locus surface of a rod side surface 3c formed when the rod rotates about a rotation axis 2, and a fixed blade 4 facing the fixed blade 4. The elastic plate 5 is fixed at a position where the movable blade 3 is sandwiched between the fixed blade and the fixed blade.

(Operation) The above technical means operates as follows.

By rotating the movable blade 3 with the drive source 1, for example, the movable blade 3 is interrupted between the noodle stick 8 and the noodle guide tube 7.
The L-shaped bent portion of the one end 3b of the movable blade 3 hooks the string 6 and pulls it out of the feeding region of the string, and when it is further rotated, the string is formed between the elastic plate 5 and the movable blade 3. Hold the body as if it were crushed. In other words, due to the elasticity of the elastic plate,
The string is elastically clamped between the movable blade and the string, but is not cut. For example, the string is elastically clamped between the movable blade 3 and the elastic plate 5 in a flattened manner as if it were stretched with a rolling pin. The movable blade further rotates, sandwiches the cord at the contact portion between the fixed blade and the movable blade, and shears like a push-cut, and then the rotation of the movable blade is stopped.

(Effect of the Invention) Therefore, the present invention has the following effects.

That is, since the movable blade has a function of hooking and pulling out the cord body by rotating, the cutting device of the present invention can be arranged without disturbing the movement movement of the cord body.

Moreover, after the string is hooked by the L-shaped portion of the movable blade 3 and pulled out in the longitudinal direction of the string, that is, in the axial direction of the through hole formed in the center of the noodle guide tube 7, the elastic plate 5 and the movable blade 3 are drawn. The cord body is clamped in the axial direction of the cord body so that the cord body is clamped between the cord body and the cord body, and the cord body is stretched by being stretched in the fiber direction of the cord body, that is, the axial direction by the traverse operation. But
Even if a tension in the direction of contraction is applied by the reaction force, the flattened state between the movable blade 3 and the elastic plate
Only the force in the pulling direction acts, and the shearing stress in the squeezing direction (the direction perpendicular to the fiber) does not work. Therefore, even if the sandwiched portion is in a flat state, the sandwiched portion is hard to be cut and can be securely held.

Further, since the elastic plate 5 is arranged parallel to the plane of rotation of the movable blade 3, the gap between the movable blade and the elastic plate is kept constant regardless of the rotation angle of the movable blade, so that a constant clamping force is always obtained. In addition, there is an effect that a series of operations of pulling out, pinching and cutting the cord can be performed with a single drive source.

(Embodiment) FIG. 1, FIG. 2, FIG. 3 and FIG. 4 show an embodiment of the present invention.

One end 3a is fixed to a rotary shaft 2 that is directly connected to a drive source 1 such as a motor or indirectly via a chain 1a, and the other end 3b is bent into an L shape, and the tip is cut to an acute angle. The movable blade 3 made of a rod body that makes it easy to hook the body, and when the rod body rotates about the rotation axis 2 as a center of rotation, the frame 6 is placed in a plane position parallel to the locus surface formed by the rod side surface 3c. A fixed blade 4 held and fixed by an installed bolt 4a is arranged in parallel to face the fixed blade 4, and when the fixed blade rotates, a locus surface opposite to the rod side surface 3 is formed. A board 5a fixed with a bolt 5b so that the flat surface portion of the board 5 is arranged on a parallel plane;
The elastic plate 5 is attached to the surface of the flat surface of the substrate 5a. As shown in FIG. 1, the cutting device of the present invention is convenient to use, for example, as a noodle string cutting device in a shaving (twilling) step in the production of hand-rolled noodles.

That is, the noodle band guide tube 7 is driven so as to perform ∞ winding in the direction of arrow B and end winding and winding at the end in the direction of arrow C,
In the chipping process of twilling the noodle strings on the two noodle sticks 8 that slide in the direction of the arrow A, the noodle strings are cut and held every time the noodle strings are full of the noodle sticks 8. The cutting device of the present invention, which can be installed so as to be out of the range of movement of the noodle band guide tube 7 during the chipping work, is optimal.

In such a device, the cutting device of the present invention is installed at a position slightly separated in front of the tip of the noodle band guide tube 7 during the shaving operation, and only when cutting, the movable blade 3 rotates in the direction of the arrow D and the tip 3b. Then, the noodle strings 9 are hooked, and the noodle strings are pulled out of the noodle string feeding range to be gripped and cut.

Specifically, it is carried out as follows, that is, when the movable blade 3 hooks the noodle strip 9 at the position indicated by the alternate long and short dash line (a) in FIG. The noodle strings 9'a on the side of the wire guide tube 7 are gripped by being sandwiched between the elastic plate 5 and one side surface of the movable blade 3 (the elastic plates 5 are recessed so that the noodle strings 9'a are cut. On the other hand, the noodle strings 9'b on the side of the noodle stick 8 are to be sandwiched between the fixed blade 4 and the other side of the movable blade 3 opposite to the above. Since the movable blade 3 pulls the noodles with the sharpened cutting edge p at the side where the fixed blades 4 first come into contact with the fixed blades 4, the noodles 9 on the noodles stick 8 side progresses as the rotation of the fixed blades 4 progresses. It will cut'b.

Thus, the movable blade 3 stops in this state, but in order to make the stop position of the movable blade 3 accurate, the click device 10 such as a ball plunger is moved to the movable blade at the position where the movable blade stops. Of course, it may be provided so as to abut.

Next, when the noodle strip 9'b on the side of the noodle strip 8 is cut as described above, this is removed, a new noodle strip 8 is attached, and the ∞-shaped motion of the noodle strip guide tube 7 is resumed. Then, the noodle strings 9 can be hung on the new noodle hanging bar 8 again in the same manner. By the way, holding the noodle strips is no longer necessary after the above-mentioned burial work is restarted, but at that time, the movable blade is rotated by a very small amount by instantaneously supplying electricity to the motor for rotating the movable blade, The noodle strips sandwiched between the elastic plates 5 are operated so as to be released. (If not done, the noodle strings 9'a gripped between them and the elastic plate 5 are draft-cut by the traveling movement of the noodle stick 8 in the direction of arrow A. (Because the release will be done automatically)
