JP6572422B2 - Noodle twisting mechanism - Google Patents

Description

The present invention relates to an apparatus for twisting a noodle string into a pair of two parallel cocoons and twisting the noodle string.

A device that crosses a pair of noodles with a diameter of about 3 to 10 mm between two pairs and a mechanism that twists and noodles the noodles when they are laid has been used in numerous patents and utility models in the past 100 years. Has been filed. Many patents and utility models are registered. There are two ways to roughly divide the cross. There is a mechanism in which the noodle strings are crossed into a pair of two ridges in a figure of 8 by causing the pair of two folds to rotate and swing while reciprocating the supplied noodle strings. The other is a method of crossing by feeding a noodle string by moving it around a pair of two non-oscillating ridges into a figure of eight. In addition, various methods have been devised for twisting the noodle strings, such as using ropes, chains, gears, racks, and magnets to rotate the nozzle at the tip of the noodle conduit when twisting.
Many of the old ones are driven by human power, and in recent years, there is a device for moving a heavy mechanism by driving a motor.
There are many ideas to achieve the goal by creating a logically accurate figure 8 movement.

The problems of the noodle string twisting devices currently on the market and the twisting devices devised in the past include a sliding reciprocating mechanism for realizing a plurality of sets of eight-shaped movements directly and indirectly. Although it could not be found in the past examples, even if the figure 8 movement was realized using a cam, it would include a sliding part. Further, in order to make one set of eight-shaped movements into two sets, it is necessary to add a sliding or parallel movement link mechanism. As another industry mechanism, there is an 8-shaped movement using a link gear mechanism. However, in order to realize the two sets of eight-shaped movements, it is necessary to add a sliding or parallel inching link mechanism as in the case of the noodle spreader. The sliding or parallel link mechanism becomes complicated due to the mechanical structure, and the moving part weight increases. And since inertia becomes large, realization of high-speed operation is not easy.

It is necessary to twist the noodle strings when the noodle strings are hung on a pair of scissors while performing the figure 8 movement. When a sliding mechanism or a parallel link mechanism is used, it is not easy to transmit rotational power to the noodle conduit of the figure 8 motion part. Many have been devised. And when a reciprocating mechanism exists, the method of obtaining twist rotational power from a reciprocating motion guide part is often seen. Since the noodle string twist rotation direction is reversed every time it is reciprocated, the twist at the rotation direction transition point is lost. In order to solve this problem, there is a twisting machine using a twisting rotation generating motor. However, since the weight of the moving part increases, it is difficult to speed up the movement of the noodle rack 8. There is also a device for twisting in a certain direction by winding instead of crossing.

A five-bar link mechanism including a fixed link A1, a rotary drive link A3, a rotary drive link A5, a long link A7, and a short link A9 is used.
The link lengths are A1> A3, A1> A5, A3 <A9, A7> A9.
The turning pair of the fixed link A1 is a1, a2 The turning pair of the rotary drive link A3 is a1, the turning pair of the a3 rotational drive link A5 is a2, the turning pair of the long link A7 is a3, and the turning pair of the short link A9 is a5 , A7, and the turning pair a7 becomes a noodle conduit and makes a figure 8 orbital motion.
The fixed link A1 is connected to the rotation drive link A3 by the turning pair a1. The fixed link A1 is connected to the rotational drive link A5 by a turning pair a2. The rotary drive link A3 is connected to the long link A7 by a turning pair a3. The rotational drive link A5 is connected to the short link A9 by a turning pair a5. The long link A7 is connected to the short link A9 by a turning pair a7 noodle conduit. By rotating the rotational drive link A3 and the rotational drive link A5 in the same direction while maintaining the same angular difference, the counter-even a7 noodle conduit can be moved to the figure 8 without interfering with a1 and a2. Reference diagram Fig. 1 Fig. 6

By adding two links, the short link A11, the long link A13, and the turning pair a11 that becomes one noodle conduit to the above-mentioned eight-character movement mechanism, two eight-character movement mechanisms can be realized.
Examples of link lengths are A3 = A5, A11 = A9, and A13 = A7.
The short link A11 is connected to the rotation drive link A3 and the long link A7 by the rotation pair a3, and the long link A13 is connected to the rotation drive link A5 and the short link A9 by the rotation pair a5. The short link A11 and the long link A13 are connected by a twisted pair a11 noodle conduit.
With this configuration, the turning pair a7 noodle conduit and the turning pair a11 noodle conduit can move in a figure 8 without interfering with other links and other pairs.
Then, the 8-shaped locus of the turning pair a7 and the turning pair a11 does not interfere with each other. Reference diagram Fig. 1 Fig. 6

The figure 8 movement mechanism of the present invention is composed only of a link mechanism that does not include a sliding portion. Therefore, the rotational power can be transmitted to the counter pair b7 noodle conduit PI02 and the counter pair b11 noodle conduit PI01 by gears, sprockets, chains, and belts without using a complicated mechanism. Reference diagram Fig. 2 Fig. 3

The sprocket SP21 is coupled to the noodle conduit PI01 so that the noodle conduit PI01 can freely rotate together with the sprocket SP21 at the counter pair b11. The combined sprocket SP17 and gear GR15 are allowed to rotate freely around the pair b3. Sprocket SP17 and sprocket SP21 are connected by chain CH17 so that power can be transmitted. The combined sprocket SP11 and gear GR13 are allowed to rotate freely around the pair b1. Power can be transmitted from the gear GR13 to the gear GR15. Drive sprocket SP10 and sprocket SP11 are connected by chain CH10 so that power can be transmitted. The noodle conduit PI01 is rotated by the rotation of the drive sprocket SP10 even during the figure 8 orbital motion. Similarly, when the drive sprocket SP10 rotates, the noodle conduit PI02 also rotates. Reference diagram Fig. 2 Fig. 3 Fig. 4

The mechanism of the present invention has no sliding part and is formed only by a rotational movement, has no linear movement and guide part, and has no reciprocating movement. Therefore, the whole mechanism has a simple structure, and the object can be achieved and speeded up by inexpensive parts.

By adding one link and two links to the five-bar link mechanism, it was possible to create two 8-shaped motion trajectories with a simple mechanism without a sliding mechanism and guide. In addition, it was possible to transmit the rotational power up to the even number around the figure 8. With a simple mechanism, we realized a mechanism that twists two noodle strings into a pair, and twists the noodle strings into two pairs.

FIG. 7 shows an embodiment mechanism of the present mechanism.
FIG. 6 is a diagram showing the positional relationship between the figure 8 trajectory of this mechanism, the positional relationship between the rotational drive pair a1, a2 on the fixed link, and the circle drawn by the pair a3, the pair a5, and the pair.

In this mechanism embodiment, the relationship of each link is as follows.
A3 = A5 A9 = A11 A7 = A13
A7>A9> A3
As shown in FIG. 1, the angle difference between the link A5 and the link A3 in the direction of movement is preferably 60 degrees to 110 degrees, and the shape of the figure 8 trajectory changes depending on the difference between the two link angles and the link length of each link.

The back side link shown in FIG. 2 moves in parallel with the front side to stably move the noodle conduit so that it does not shake. The link length is exactly the same as the front side. The difference is that it has a function of transmitting the rotational power of the noodle conduit using the pair of the back link. The noodle conduit rotation power transmission unit is between the front side link mechanism and the back side link mechanism. As a result, the final power transmission destination noodle conduit is transmitted to the intermediate point supported by the two-sided pair of the front side link mechanism and the back side link mechanism.

It is desirable that the noodle conduits rotate a lot during the 8-shaped movement of one cycle. This is because the noodle is twisted at the tip noodle twist nozzle portion by rotating the noodle conduit. This mechanism can rotate more than 8 times per 8 cycles of one cycle. In the conventional twister, only the nozzle at the tip of the noodle conduit is rotated. For this reason, power transmission is complicated. In this mechanism, the noodle conduit itself is rotated. This facilitates nozzle rotation power transmission. However, since the noodle conduit is rotating at a high speed, the noodle strings adhere to the inner wall of the noodle conduit due to centrifugal force and are broken in the noodle conduit. In order to prevent this adhesion, the noodle string rotation restraining spring in the CO01 CO02 noodle conduit is inserted into the noodle duct and the noodle string is passed through the spring to inhibit the noodle string rotation in the noodle conduit. The noodle strings rotation restraining spring in the noodle conduit can be semi-fixed near the noodle string inlets IN01 and IN02. In addition to the spring, a net-like, bowl-like, or plate-like material can be used as a tube in order to suppress the rotation in the noodle conduit.

Further, the noodle string rotation restraining spring in the noodle conduit can be extracted from the noodle conduit. Pass the noodle strings in the noodle conduit extracted from the noodle conduit, and then put it in the noodle conduit, remove the noodle conduit tip noodle twist nozzle at the tip of the noodle conduit, and remove the noodle strand that reaches the tip of the noodle conduit. After passing through the pick-up nozzle, the noodle strings are attached to the bowl and the operation is started.

FIG. 7 is a diagram showing two pairs of cocoons and two sets of noodles twisted using this mechanism.

It is possible to create two sets of 8 figure trajectories that have a free rotation motion independent of the figure 8 movement speed with a chain and gear power transmission mechanism in a simple mechanism of 6 link pairs and 7 link plates. Possibility can be considered not only for noodle twisting of hand-rolled noodles but also in the fields of knitting, painting, stirring and chaos.
