Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a method of folding noodles in half into one serving of noodles, which are made by gathering a large number of noodle strings into a band shape and cutting the strips into a predetermined length. It is something that forms.

[Conventional technology]

An example of an invention for folding noodles in half is by Tokkosho.
There is one such as that described in Publication No. 51-42187.
In this prior art, noodles are cut into a predetermined length and fed hanging down by a pair of holding rolls, and the central part is pushed by a bending blade to fold the noodles in half, and the folded noodles are placed under one of the holding rolls. The transfer is carried out on the upper surface of the transfer belt located at the top of the transfer zone. The bending blade is fixed to the tip of a lever that swings back and forth at the same speed, and moves back and forth along an arcuate trajectory.

[Problem that the invention seeks to solve]

However, in such conventional technology, after the folding blade pushes the noodles in the previous stage, the folding blade continues to push the noodles as a means for feeding the noodles folded in half onto the upper surface of the conveying body. In this case, the noodles were moved sufficiently far from the end of the transfer body only by the movement of the folding blade, and most of the load of the noodles was transferred onto the transfer body, so the forward and backward stroke of the folding blade was becomes large. In addition, if this advance/retreat stalk becomes large, there is a risk that the next noodle will be fed before the folding blade has fully returned, causing interference between the receding folding blade and the supplied noodle. speed must be increased. In this way, if the advancing and retreating speed of the folding blade is high compared to the speed at which the noodles are fed, the timing between the noodles being fed and the advancing folding blade will be misaligned, and the tip of the folding blade will be in contact with the noodles. There is a problem in that the hitting position tends to be misaligned.

In this case, since the tip of the folding blade does not touch the noodle at a predetermined position, the folding position is not at the center of the noodle, resulting in a problem that the rear end of the noodle that is folded in half becomes uneven.

In addition, since the trajectory of the bending blade is arc-shaped, the tip of the bending blade touches the noodles and then moves the noodles.
This is also 2 because the folded noodles will draw an arc.
This is one of the reasons why the rear end of the folded noodles is uneven.

This invention was made by focusing on the problems of the prior art, and aims to fold noodles in half so that the rear ends of the noodles are aligned.

[Means for solving problems]

The present invention relates to a method and device for folding noodles into two, and the method includes folding noodles into two to a predetermined length.
A method of supplying the noodles by passing between two rotating parts, and folding the noodles in half by pushing the longitudinal center of the noodles with a folding blade, and feeding the noodles onto a carry-out conveyor. The distance between one of the rotating parts and the carry-out conveyor is made smaller than the thickness of the two folds, and the noodle supply speed by both rotating parts, the carry-out speed of the carry-out conveyor, and the forward speed of the folding blade are made approximately equal. By advancing, the supplied noodles are folded in half and the folded end is pushed between the delivery conveyor and the rotating part,
While the folding blade is moved back at a faster speed than when moving forward, the pushed noodle is held between the carry-out conveyor and the rotating part and received, and the folded noodles are carried out as they are by the carry-out conveyor.

Here, the above-mentioned speeds being roughly equal means that the speeds of the members on both sides that press the noodles from both sides are the same, but even if their speeds are different, there is no possibility of cutting the noodle strings, crushing the noodles, etc. This also includes speed differences that do not adversely affect the shape, quality, etc. of the noodles. This is because the lid and noodles have resilience due to their elasticity, so even if there is a certain degree of speed difference between the two sides, they have the property of restoring when released from the restraints from both sides.

In addition, the device directly used to carry out the above method has two rotating parts that sandwich noodles cut to a predetermined length from both sides and feed them at a predetermined speed, and one rotating part that holds noodles cut in half. A discharge conveyor is arranged at a distance smaller than the thickness and has a discharge speed approximately equal to that of the rotating section, and the conveyor is moved forward toward the distance between the rotary section and the discharge conveyor, and is moved by both rotating sections. It consists of a bending blade that pushes the longitudinal center portion of the supplied noodles into the space at a speed roughly equivalent to that of the delivery conveyor, and the bending blade is connected to a slider that reciprocates along a linear guide. This slider is connected to a quick return mechanism.

〔Example〕

The illustrated embodiment will be described below.

Reference numeral 1 indicates noodles, which are transported by a transport conveyor 2. The carry-in conveyor 2 normally consists of a stainless steel net conveyor. The noodles 1 carried in by the carrying-in conveyor 2 are made up of a large number of waved noodle strands gathered together in a band shape, and have already been gelatinized by steam.

The noodles 1 carried in by the carry-in conveyor 2 are introduced into the cutter 3 from the tip of the carry-in conveyor 2, where they are cut into a predetermined length, and thus become the noodles 1 of one serving size. At this stage, when noodles 1 are cut,
The lower part of the noodle 1 is sandwiched between two rotating parts 4 and 5 and guided downward by the rotation of the rotating parts 4 and 5. The rotating parts 4 and 5 each consist of a roller, and their circumferential speeds are the same or slightly faster in the rotating part 5.
Further, the interval between the rotating parts 4 and 5 is set to be slightly smaller than the thickness of the noodles 1, so that the noodles 1 are guided and fed downward while being sandwiched between the two rotating parts 4 and 5.

When the cut noodle 1 is suspended by the rotating parts 4 and 5, the bending blade 6 moves forward from the side in the center of the length direction of the noodle 1 (the state shown in FIG. Press the center to start folding noodles 1 in half.

In front of the folding blade 6, a gap 8 is formed between the rotary part 5 and the delivery conveyor 7 below it, and within this gap 8, the noodles 1 which have been folded in half by the folding blade 6 are placed. The bent end of is pushed in.

The speed of the unloading conveyor 7 is approximately the same as the circumferential speed of the rotating part 5, and the unloading conveyor 7
is installed horizontally here, but it may also be inclined upward or downward. The distance 8 between the carry-out conveyor 7 and the rotating section 5 is smaller than the thickness dimension when the noodles 1 are folded in half, and the rotating section 5 and the carrying-out conveyor 7 handle the folded end of the noodles 1 in half. It is designed to be sandwiched.

The two-folded end of the sandwiched noodle 1 is connected to the rotating part 5
Due to the rotation of the noodles 1 and the operation of the delivery conveyor 7, the noodles 1 are forcibly moved to the front of the delivery conveyor 7, and the noodles 1 are gradually stacked up to the rear end, and the entire noodles 1 are folded in half, and then released from the rotating part 5. In this state, it is placed on the upper surface of the carry-out conveyor 7 and carried out to the next process.

The folding blade 6 that has pushed the center of the noodle 1 into the gap 8 between the rotating part 5 and the carry-out conveyor 7 starts to retreat when the folded end of the noodle 1 is caught in the gap 8. This backward movement is performed at a faster speed than the forward movement. That is, the bending blade 6 is fixed via a plate 11 to a slider 10 that reciprocates along a linear guide 9, and the slider 10 is connected to a quick return mechanism 12.

The quick return mechanism 12 is constituted by a biased slider crank mechanism in this embodiment. That is, the drive shaft 12
The tip of the link 12b fixed to the pin 12
The tip of the link 12c is pivotally connected to the slider 10 by d, and the tip of the link 12c is pivotally connected to the slider 10 by a pin 12e,
It constitutes the quick return mechanism 12.

The guide 9 is installed between brackets 13, 13 fixed to a machine frame (not shown), and the drive shaft 12a is connected to a known rotary drive source (not shown).

The movement of each part of the quick return mechanism 12 is shown in FIG. That is, in the same figure, 12a
is the center of the drive shaft 12a, and 12e is the center of the pin 12
12d is the circular orbit of pin 12d, and 12d is the advancing and retreating orbit of pin 12d. In the same figure, the position of pin 12e is a
The position of the pin 12d when the pin 12d is in the position is indicated by A, and similarly, as the moving position of the pin 12e changes to b, c, d..., the position of the pin 12d changes to B, C, D.
...changes. And positions a, b, c, d...
The distances between them are equal, but the positions A, B, C, D
...The distance between them is different. That is, in the quick return mechanism 12, when the link 12b rotates at a constant speed, the pin 12d moves backward from position A to position I until the pin 12e moves from position a to position i, and the pin 12e moves back from position i to position i. The pin 12d moves forward from I to X until it moves to position x. Thus, it can be understood that the backward speed of the pin 12d is greater than the forward speed of the pin 12d.

Then, the movement of the pin 12d and the bending blade 6
Since the forward and backward movement of the bending blade 6 is performed integrally, the backward speed of the bending blade 6 is faster than that of the forward movement. Also, the bending blade 6
The forward speed of the rotating portion 5 is approximately equal to the circumferential speed of the rotating portion 5. In this way, after the noodles 1 are sandwiched between the gaps 8 as described above, the subsequent noodles 1 are placed between the rotating parts 4 and 5.
It is possible to complete the rear end before being guided by the machine and prepare for the next operation. Therefore, there is no possibility that the retreating bending blade 6 will interfere with the following noodles 1.

Furthermore, since the forward and backward speeds of the bending blade 6 are made different and the backward speed is increased as described above, there is no need to increase the forward speed in accordance with the backward speed as in the conventional example. Therefore, the forward timing of the bending blade 6 is adjusted so that the tip of the bending blade 6
This makes it easier to control the area so that it hits the center of the area. Furthermore, since the bending blade 6 advances and retreats in a straight line along the guide 9, it comes into contact with the noodles 1 guided from the rotating parts 4 and 5 at right angles, and the noodles 1 can be pushed directly toward the interval 8. , the force of the bending blade 6 is not biased toward either the upper half or the lower half of the noodles 1. Therefore, the rear end of the noodles 1 folded in half will not be uneven.

As described above, the circumferential speeds of the rotating parts 4 and 5 are approximately equal, the forward speed of the folding blade 6 is approximately equal to the speed of the noodles 1 supplied by the rotating parts 4 and 5, and the speed of the delivery conveyor 7 is approximately equal. Rotating part 5
Since it is approximately equal to the circumferential speed of noodle 1,
When folding, no excessive force is applied to the noodles 1.

In addition, in this embodiment, the width dimension (perpendicular to the drawing in FIG. 1) of the carry-in conveyor 2, the cutter 3, the rotating parts 4 and 5, the bending blade 6, and the carry-out conveyor 7 is large. , and the noodles 1 are arranged in a plurality of rows, and the noodles 1 in each row are processed at the same time. Two guides 9 are installed in parallel, a slider 10 is spanned between both guides 9, and one quick return mechanism 12 is connected to the slider 10. Furthermore, if the cutter 3 of the above embodiment is placed on the upper surface of the conveyor 2 where the noodles 1 flow easily, the rotary part 4 can be placed at the tip of the conveyor 2.
A rotating part 5 is disposed opposite to the tip of the carry-in conveyor 2, and the noodles 1 can be guided and suspended between the tip of the carry-in conveyor 2 and the rotating part 5 in the same manner as the rotating parts 4 and 5.

〔Effect of the invention〕

As explained above, according to the present invention, the distance between the rotating part and the delivery conveyor is made smaller than the thickness of the noodle folded in half, so that when the folded end of the noodle that has started to be folded in half is caught between the parts, , the noodles are forcibly drawn in by the rotating part and the delivery conveyor,
Since the noodle is discharged by the carry-out conveyor after the folding process is completed, there is no need to carry the noodles to the back of the carry-out conveyor using a folding blade as in the conventional example. Therefore, a small forward and backward stroke of the bending blade is sufficient. Furthermore, since the folding blade advances and retreats at a retreating speed faster than its forward speed, combined with the reduction in the stroke, there is no risk of interference between the following noodles and the folding blade. This has the effect of eliminating errors in folding the noodles by the folding blade.

Furthermore, since the forward and backward speeds of the bending blade are made different and the backward speed is made faster as described above, there is no need to increase the forward speed in accordance with the backward speed as in the conventional example. Therefore, it becomes easy to control the forward timing of the folding blade so that the tip of the folding blade hits the center of the noodles. Furthermore, since the bending blade advances and retreats in a straight line, it comes in straight contact with the noodles guided from the rotating part.
Since the noodles can be pushed directly toward the gap, the force of the bending blade will not be biased toward one half of the noodles or the other half. Therefore, there is no possibility that the rear end of the noodles folded in half will be uneven, and it is possible to produce high-quality noodles.
