Description

[Detailed description of the invention] <Industrial application field> This invention is a device that automatically rolls (stretches) and then cuts the dough for noodles such as Japanese soba, udon, kishimen, and Chinese soba. The present invention relates to a cutting device for noodle making that can prevent misalignment of dough during cutting operation.

<Prior art> For example, a conventional noodle-making device rolls rolled dough, which is transported at a predetermined speed by an endlessly stretched conveyor belt, in a predetermined direction perpendicular to the dough transport direction. There are some that are equipped with a cutting blade that cuts with a width of . This cutting blade is configured to cut the fabric while moving up and down and simultaneously reciprocating in the length direction (lateral direction) of the blade, so the fabric on the belt is pushed by the force of the cutting blade. It often bounces in the vertical direction or shifts in position in the lateral direction, and as a result, it is difficult to maintain a constant shape of the cut fabric. For this reason, recently, a roller is placed in front of the cutting blade to prevent misalignment, and by pressing the fabric, it is possible to prevent misalignment of the fabric (especially misalignment in the lateral direction).
It is configured to prevent This roller for preventing positional shift is a long body made of an elastic material such as a sponge that is spirally wound around the outer periphery of a rotating shaft. It is configured.

<Problems to be solved by the invention> In the conventional cutting device of the noodle making machine as described above, the dough was pressed by a spiral sponge on the outer circumferential surface of the roller to prevent the dough from shifting. , the presser force was weak and positioning and holding was not reliable. That is, depending on conditions such as the sharpness of the blade, the strength of the movement of the blade, the thickness of the fabric, and the strength of the waist of the fabric, the force for positioning and holding the fabric may be insufficient.
Misalignment of the dough often occurred, resulting in uneven shapes of noodles after cutting. In particular, if a positional shift occurs in the direction (lateral direction) perpendicular to the conveying direction of the fabric, this is a problem because the cutting width and shape become significantly non-uniform.

<Means for Solving the Problems> The device of the present invention for solving the above-mentioned problems includes a conveyor belt 5 stretched endlessly to convey rolled dough 37, and In a noodle-making cutting device equipped with a cutting blade 40 that cuts the rolled dough 37 into a predetermined width while moving up and down in the vertical direction including lateral movement, the dough is placed on the conveyor belt 5 in front of the cutting blade 40. A displacement prevention roller 42 that presses 37 from the upper surface is rotatably disposed.
The positional shift prevention roller 42 has a rod-shaped shaft portion 42a.
and a flange-shaped pressing piece 42b coaxially protruding from the shaft portion 42a at an axial distance 42c, and the pressing piece 42b is attached to the conveyor belt 5.
The peripheral surface presses against the upper surface of the rolled dough 37 being conveyed thereon and is slightly depressed, thereby preventing displacement in the lateral direction when cutting the rolled dough.

<Function> In the device of the present invention, the rolled dough being conveyed toward the cutting blade by the conveyor belt is conveyed by the roller 42 disposed in front of the cutting blade 40 to prevent displacement. It is pressed onto the belt 5 and held in position. This roller 42 is made up of a plurality of cylindrical flange-shaped pressing pieces 42b coaxially fitted together or rotatably fitted at predetermined intervals on a rod-shaped rotating shaft 42a. It is rotatably supported by support parts 44 that are arranged opposite to each other on both sides of the direction. By pressing the upper surface of the fabric with the outer peripheral surface of each cylindrical pressing piece, reliable and firm positioning is achieved.
Therefore, even when the cutting blade 40 performs the cutting operation while reciprocating in the vertical direction and the width direction (lateral direction) of the belt 5, the fabric does not shift in position in the lateral direction. Therefore, cutting can always be performed with uniform width and shape.

<Embodiment> Figures 2 to 4 show an embodiment of a noodle-making device to which the cutting device of the present invention is applied. ，
4 is rotatably supported on a shaft, and an endless belt 5 having a constant width and made of elastic material such as rubber or resin is wrapped around the rollers 3 and 4 at both ends. At intermediate positions between the end rollers 3 and 4, receiving rollers 6 and 7 are supported horizontally and parallel to the respective rollers at regular intervals so as to be accommodated within the belt 5.

One side of the chain wheel 9 is connected to a drive device 10 consisting of a motor with a clutch, and the end roller 3 is connected to the drive device 10. This is a mechanism in which the belt 5 is reversibly rotated left and right together with the end rollers 3 and receiving rollers 6 and 7. Above the intermediate portion of the receiving rollers 6 and 7, a pressure roller 11 having the same diameter is supported in parallel with these rollers so as to be movable up and down by the upper ends of a pair of opposing swing frames 12, which will be described below. The swinging frame 12 is swingably supported at its left base end by a shaft 13, and is provided with a cam seat 14 projecting approximately horizontally at its right end.
A roller frame 12a that pivotally supports the pressure roller 11 is protruded above.

Further, at the lower right end of the swing frame, return levers 15 are provided so as to face the cam seats 14, and the return levers 15 and the cam seats 14 opposite thereto are provided.
A bolt 17 having an end plate 16 at the lower end is inserted into each tip of the bolt 17 , and a return adjustment screw 18 is screwed into the protruding upper end of the bolt 17 . A strong return spring 19 is inserted in which always urges the return lever 15 upward.

The swinging frames 12 having the above configuration are provided in pairs on both sides of the main body in the width direction, and an eccentric cam 20 is supported horizontally on the main body 1 between each cam seat 14 and the return lever 15. It is eccentrically rotatably supported by a camshaft 21 that is
The cam 20 is constantly pressed against the return lever 15 on its lower side by a return spring 19, and has a cam seat 14 placed on its upper surface.

A chain wheel 22 is integrated into the cam 20 coaxially with the cam shaft 21, and an adjustment handle 23 is rotatably supported below the cam 20. The adjustment handle 23 has a rotating shaft 23a.
A coaxial chain wheel 24 is integrated, and both chain wheels 22 and 24 are connected by a chain 25, and by adjusting the rotation angle of the adjustment handle 23, the vertical position of the swing frame 12 can be adjusted. It is configured.

Furthermore, in order to stop the vertical movement of the pressure roller 11 and set and lock the distance between the pressure roller 11 and the receiving rollers 6 and 7, it is necessary to lock the swinging of the swing frame 12 in a fixed position. For this purpose, it is desirable to provide a mechanism (not shown) for arbitrarily locking the swing frame 12 to the main body frame.

Regardless of the adjustment of the cam 20, the swing frame 1
In order to lock the swing frame 12, it is desirable to provide a mechanism (not shown as it is easily possible with well-known technology) for fastening and fixing the swing frame 12 to the main body 1 at an arbitrary position.

Inside the swing frame 12 on the front side,
The swing frame support shaft 13, the pressure roller shaft 27, and the receiving roller shaft 28 are each provided with a chain foil 29
30 and 31 are provided, among which the chain wheel 31 of the receiving roller shaft 28 is a double sprocket. Further, a tension wheel 32 is provided on the lower half of the swing frame 12 so that its axial position can be freely adjusted.

In the arrangement of the respective foils as described above, an endless chain 33 is wound around the chain foil 9 of the end roller shaft 8 and the chain foil 31 of the receiving roller shaft 28, so that both the wheels 9 and 31 rotate simultaneously in the same direction, and Chain foil 30 of pressure roller shaft 27

The endless chain 34 is wound around the receiving roller shaft 28 between the chain foils 29 and 30.
The outside is wrapped around.

In the belt 5 between the end roller 3 and the receiving roller 6 and between the end roller 4 and the receiving roller 7,
Belt guides 35 and 36 are fixedly provided to the main body 1 so as to slide on the upper inner surface of the belt 5 and horizontally support it.

When cutting the rolled dough with a cutter (cutting blade) 40, the belt 5 cuts the cutter 4 at a predetermined interval.
It is configured to move intermittently toward zero. The cutter 40 is disposed, for example, directly above the end roller 4, and is moved up and down by, for example, the motor 10 (or a separate motor, not shown) in response to the intermittent movement of the belt 5. Then, the rolled dough on the belt 5 is transferred to the cutter 4 according to the intermittent movement length of the belt 5.
0 and are sequentially disconnected.

In front of the cutter 40 (left side in Figure 2) are a wrinkle smoothing roller 41 and a misalignment prevention roller 4.
2 are placed respectively. These are all attached when cutting the rolled dough, and are attached to the support grooves 44a, 4 of the support portions 44 (FIG. 1) disposed opposite to each other on both sides of the belt 5 in the width direction.
Each rotating shaft is rotatably supported by 4b, and is pressed against the upper surface of the rolled material by a spring or its own weight. When the fabric is conveyed toward the cutter, it is configured to roll due to the frictional force with the upper surface of the fabric. The misalignment prevention roller 42 is a metal roller having a plurality of flanges protruding from its outer peripheral surface at predetermined intervals in the axial direction. A plurality of cylindrical (flange-shaped) pressing pieces 4 coaxially and integrally formed to protrude at predetermined intervals on the outer periphery.
2b. The outer circumferential surface of the cylindrical pressing piece 42b may be smooth without any unevenness, or it may be formed with unevenness to increase the frictional resistance, but in either case, it will not damage the fabric. Moreover, it is preferable that the structure is such that sufficient pressing force or frictional resistance against the fabric can be ensured.

Next, I will explain the noodle making process using the noodle making device configured as above, especially the making of Japanese soba noodles.
First, the device is operated by intermittently rotating the drive device 10 in left and right opposite directions so that the belt 5 alternately rotates about 1/4 of its total length, and in accordance with the rotation of the belt, the pressure roller 11 is The belt 5 is operated to rotate in the opposite direction, and a lump of dough 37 made by kneading material powder and water is placed on the right or left upper surface of the belt 5. At this time, the circumferential speed of the belt 5 is, for example, 2.5 to 4.0 m/min.

At this time, depending on the amount and nature of the dough, the pressure roller 1
The angle of the cam 20 is adjusted by a handle 23 so as to adjust the distance between the cam 1 and the receiving rollers 6 and 7, and the strength of the return spring 19 is adjusted by an adjustment screw 18.

Each time the fabric 37 on the belt 5 moves left and right with the belt 5, it is drawn between the pressure roller 11 and the belt 5 on the rollers 6 and 7 and passes from side to side. Kneading is repeated between 6 and 7 under strong pressure and contact friction to impart and maintain the necessary stickiness to the noodles.

Next, the cam 20 and adjustment screw 18 are tightened so as to sequentially narrow the gap between the pressure roller 11 and the receiving rollers 6 and 7.
, and while continuing to move the belt 5 from side to side,
Perform rough stretching in step 7 and roll thinly. At this time, when the dough is longer than the top surface length of the belt 5, the end of the rolled dough passing between the pressure rollers 11, 6, and 7 is wound up with other rollers or rods in turn at one end, and then rolled up at the other end. Return it. These winding and unwinding operations may be performed manually or by using the belt 5 of the main body 1.
This can be done manually or mechanically by pivotally supporting rolls (not shown) for winding and unwinding on both left and right sides of the top.

When the dough reaches a certain thickness by the above-mentioned rolling, in order to make the final thickness uniform, the swinging frame 12 stops swinging, and the swinging frame 12 is moved so that the distance between the pressure roller 11 and the pressure rollers 6 and 7 is constant. lower into position and lock. In the illustrated embodiment, the adjustment handle 23 is rotated to the left and locked by a locking mechanism (not shown) (using a conventional method).

When the swinging frame 12 is locked and the dough is further rolled, the dough is uniformed to a desired thickness of about 1 mm to 5 mm, and the dough is then cut into predetermined widths and lengths to complete raw noodles.

After completing the rolling of the dough in this way, the cutter 40
When proceeding to the cutting process, first, the belt 5 is switched to intermittent drive using an intermittent drive device (not shown), and the cutter 40 is set.
Next, the wrinkle smoothing roller 41 and the misalignment prevention roller 42 are inserted into the support groove 4 of the support section 44, respectively.
4a, 44b. In the rolling process, which is the previous process, if a roller or bar for winding and unwinding is used, the fabric is wound and held on the roller or bar near the end roller 3, and the back end side of the fabric (cutting side) is ) Feed toward the cutter 40 from the end. At this time, the fabric is sequentially rewound from the rollers or rods closer to the end roller 3. Flange-shaped pressing piece 4 on the outer circumferential surface of the misalignment prevention roller 42
2b is in pressure contact with the upper surface of the fabric while rolling with a predetermined pressing force due to its own weight or a spring, so that the pressing piece 4
The outer peripheral surface of 2b digs into the upper surface of the dough, albeit slightly. Moreover, since there is a recess between each pressing piece 42b, this serves as a resistance and prevents the fabric from sliding sideways. That is, in order to improve cutting efficiency, the cutter 40 reciprocates in the length direction of the blade (in the width direction of the conveyor belt 5, that is, in the lateral direction) at the same time as it reciprocates in the vertical direction. Movement may cause the uncut fabric located in the front to slide sideways. However, the positional deviation prevention roller 42b
According to the method, it is possible to completely prevent such lateral positional deviation and the occurrence of non-uniform cut shapes due to the positional deviation.

5a and 5b show another embodiment of the present invention, in which the same parts as those in the previous embodiment are denoted by the same reference numerals and redundant explanation will be omitted. This embodiment differs from the previous embodiment in that the cutter 40 is disposed at a rear position than the reversing section (composed of rollers 4), and a receiving plate 45 is fixedly disposed directly below the cutter 40. The receiving plate 45 is, for example, as shown in FIG. 5b, an elastic plate 47 made of rubber or the like is attached to the upper surface of a base 46 made of iron or wood, and the end rollers are arranged at a predetermined inclination angle. It is arranged close to the rear (on substantially the same plane as the belt 5). Fabric 37 discharged backward from end roller 4
advances to the upper surface of the receiving plate 45 and is cut into a predetermined width by the cutter 40. In the above embodiment,
The cutter 40 uses the conveyor belt 5 as a mana plate,
This often damages the upper surface of the conveyor belt, but in this embodiment, the conveyor belt and the mandrel plate are separate, so that damage to the belt can be prevented.

<Effect of the invention> According to the invention configured as described above, the main body 1
In front of the cutter 40 disposed near the reversing section at the rear end of the upper conveyor belt 5, the rolled dough being conveyed is prevented from shifting in the lateral direction by a displacement prevention roller 42. Therefore, the fabric does not slide sideways due to the lateral rolling movement of the cutter 40, and as a result, a uniform cut shape can always be obtained.

Furthermore, since the above-mentioned misalignment prevention roller is always in contact with the fabric and rotates as the fabric moves, there is no need to raise it up and separate it from the fabric when moving the fabric, and there is no need for a structure for this purpose. Since it only needs to be placed on the upper surface of the fabric and supported so as to rotate, it has the advantage of being simple in structure and low in cost.
