The adjacent chopsticks pair devices 110 are opened and closed synchronously by meshing the paired gears.

In consideration of preventing interference between the adjacent chopsticks 114, the interval between the adjacent chopstick devices 109 is at least that of the crank arm 112 more than the maximum longitudinal interval between both chopsticks 111 in any chopstick device 109. It must be set wider than the length obtained by adding the diameter of the eccentric shaft and twice the thickness of the noodle strings, which limits the size reduction of the large drawing machine.
JP-A-9-135655

  An object of the present invention is to provide a large pulling machine that exceeds this limitation and is smaller than conventional ones.

  In order to achieve this object, in the present invention, a plurality of pairs of upper and lower tubes each having noodle strings wound in an 8-character shape are supported side by side, and the noodle strings are stretched by expanding the vertical space between the tubes. Large pulling machine equipped with a noodle dividing device that inserts a pair of chopsticks between the device and the noodle strings wound on each pair of upper and lower tubes, and lifts and lowers while rotating eccentrically in opposite directions. The noodle dispensing device comprises a delay means for delaying the rotation of the adjacent pair of chopsticks by 180 ° with respect to the rotation of the pair of chopsticks forming an arbitrary pair, Adopted.

  According to the present invention, all the front and rear pairs of chopsticks are closed and inserted into the noodle string ring, and then the arbitrary front and rear pairs of chopsticks are rotated 180 ° eccentrically to the maximum open state. To do. While this arbitrary front / rear pair of chopsticks is rotated 180 ° eccentrically, the rotation of this arbitrary front / rear pair of chopsticks is not transmitted to the adjacent front / rear pair of chopsticks, and this adjacent front / rear pair is formed. The chopsticks are kept closed.

  After the chopsticks forming the arbitrary front / rear pair are eccentrically rotated by 180 °, the delay means is operated to rotate the chopsticks forming the adjacent front / rear pair eccentrically with the rotation of the chopsticks forming the arbitrary front / rear pair. When the chopsticks forming an arbitrary front / rear pair are closed again, the adjacent pair of chopsticks is opened to the maximum, and then the opening / closing state of the adjacent chopsticks forming the front / rear pair is reversed. The chopsticks are raised or lowered while rotating eccentrically.

  When the chopsticks are raised to a predetermined height or processed, the chopsticks are pulled out to the left or right side of the noodle strings, and after that, the chopsticks forming any pair of front and rear are opened to the maximum. By rotating backward by 180 °, the chopsticks forming each pair of front and rear are aligned to prepare for the next noodle dispensing operation.

  In this way, when the noodle chopping work is eccentrically rotated so that the open / closed state of the adjacent chopsticks is opposite to each other, the distance between the adjacent chopsticks is changed to the eccentricity of the chopsticks. Even if it is narrowed to near the turning radius, it is possible to prevent the noodle strings lined up in the front and back from contacting each other.

  In the present invention, adjacent chopsticks forming a pair of front and rear are linked to different motors, and after the delay means starts these motors and one of these motors, the linked chopsticks are linked to the motors. It may be configured to include an electrical delay control circuit that starts another motor when the chopsticks are rotated 180 ° eccentrically after starting.

  However, in this case, two expensive motors that can accurately control the rotation phase are required, which is disadvantageous in reducing the cost, and when a large number of paired chopsticks are provided. The problem arises that the structure of the power system that transmits power from the motor to the chopsticks becomes complicated.

  Therefore, in the present invention, it is recommended that the delay means be provided with a delay transmission mechanism that mechanically delays rotation of the chopsticks forming an arbitrary front / rear pair to the adjacent chopsticks adjacent thereto by 180 °. Is done.

  The delay transmission mechanism may be configured to transmit the rotation of the chopsticks forming an arbitrary front / rear pair to the adjacent chopsticks adjacent to the front / rear pair with a mechanical delay of 180 °. The first rotating plate interlocked with one of the pair of chopsticks adjacent to each other and the second rotating plate interlocked with the other are provided, and one rotating plate of the first and second rotating plates has both rotations. A transmission pin that is eccentric from the rotation axis of the plate and protrudes toward the other rotation plate is provided, and the other half of the transmission pin plunges 180 degrees around the rotation axis of both rotation plates so as to be freely movable. What is necessary is just to employ | adopt the structure that the circular arc groove is formed.

  As described above, the present invention is characterized in that the noodle dispensing device includes delay means for delaying the rotation of the adjacent pair of chopsticks by 180 ° with respect to the rotation of the pair of divided chopsticks. Therefore, even if the distance between adjacent chopsticks forming a pair of front and rear is reduced to near the eccentric rotation radius of the chopsticks, it is possible to prevent the noodle strings lined up and down from coming into contact with each other. It is possible to obtain an effect that the size of the large drawing machine can be reduced by narrowing the distance between the front and rear of the paired chopsticks.
