Description

The present invention relates to a noodle strip rolling apparatus that pulls out a noodle strip wound on a take-up rod and rolls it with a pair of rolling rolls.

Conventionally, the inclined surface of the V-shaped or U-shaped receiving groove formed in the installation portion where the winding rod is installed supports the winding rod on which the noodle band is wound, and is wound by this winding rod. A noodle strip rolling apparatus is known in which a noodle strip is drawn between a pair of rolling rolls and rolled (see, for example, Patent Document 1).

JP-A-2018-174803

Here, the noodle band wound around the winding rod is tightened in the winding process as it is closer to the center, and the winding pressure is applied, and the noodle band spreads in the axial direction and both ends protrude in a conical shape. On the other hand, in the conventional noodle band rolling apparatus, since the load that regulates the rotation is obtained by the weight of the noodle band itself, the load that regulates the rotation of the winding rod when the noodle band on the winding center side is pulled in. Could not be increased. Therefore, when the noodle band is pulled between the pair of rolling rolls in the conventional noodle band rolling apparatus, the noodle band located outside the winding is pulled in with the desired width, but is wider than the desired width. The noodle strip near the center of winding was not pulled in with the desired width of the noodle strip, and there was a problem that the portion protruding from the rolling roll width was folded or wrinkled.

The present invention has been made by paying attention to the above problems, and provides a noodle strip rolling apparatus capable of adjusting the tension acting on the noodle strips drawn into a pair of rolling rolls to adjust the desired noodle strip width. With the goal.

In order to achieve the above object, the noodle band rolling apparatus of the present invention includes an installation portion for installing a winding rod around which the noodle band is wound, and a pair of rolling rolls, and the noodle band wound around the winding rod. Is pulled between a pair of rolling rolls and rolled. A load that rotatably supports the take-up rod and regulates the rotation of the take-up rod when the amount of the wound noodle band is small is higher than when the amount of the noodle band is large. A rotation control means was provided to give a large amount of.

In the present invention, when the amount of the noodle band wound on the take-up bar is small and the noodle band near the take-up center of the take-up bar is drawn between the pair of rolling rolls, it is wound around the take-up bar by the rotation regulating means. It is possible to give a greater load to regulate the rotation of the take-up rod than when the amount of noodle strips taken is large. As a result, the noodle band on the winding center side, which has expanded in the width direction due to the winding tightening, can be contracted in the width direction by applying a necessary tension. Therefore, the noodle band drawn between the pair of rolling rolls can be adjusted to the desired width of the noodle band.

Hereinafter, embodiments for carrying out the noodle strip rolling apparatus of the present invention will be described with reference to Examples 1 and 2 shown in the drawings.

(Example 1)
Hereinafter, the overall configuration of the noodle strip rolling apparatus 1 in the first embodiment will be described with reference to FIGS. 1 and 2.

The noodle band rolling apparatus 1 of the first embodiment is a roll-type noodle making machine for producing noodle dough used for udon, soba, ramen, wonton and the like. The noodle band rolling apparatus 1 rolls noodle dough (hereinafter referred to as “noodle band M”) formed into a band by kneading wheat flour, water, and other materials with a pair of rolling rolls 31 and 32. At this time, the noodle band M is previously wound into a roll shape by the winding rod 10, and is pulled out from the noodle band wound around the winding rod 10 (hereinafter referred to as “roll-shaped noodle band m”). The noodle strip M is drawn into the rolling interval 33 formed between the pair of rolling rolls 31 and 32.

When the noodle strip M is rolled, both ends of the take-up rod 10 are supported by the gutter-shaped noodle strip support rail 11 (installation portion) provided in the noodle strip rolling apparatus 1. That is, the noodle band rolling apparatus 1 includes a noodle band support rail 11 for installing a winding rod 10 around which the noodle band M is wound, and a pair of rolling rolls 31 for rolling the noodle band M wound around the winding rod 10. , 32 and. The noodle band support rail 11 is attached to the upper part of the apparatus housing 12 that houses the pair of rolling rolls 31 and 32.

A rotation regulating means 20 is provided on the noodle band support rail 11 on which the take-up rod 10 is installed. The rotation regulating means 20 rotatably supports both ends of the take-up rod 10 and winds the roll-shaped noodle band m in a small amount than in a state in which the roll-shaped noodle band m has a large amount. A load that regulates the rotation of the rod 10 (hereinafter, “rotation-regulated load”) is largely applied to the take-up rod 10. That is, the take-up rod 10 is less likely to rotate when the amount of the roll-shaped noodle band m is small.

Here, when "the amount of the roll-shaped noodle band m is large", the roll-shaped noodle band m is heavy and the winding diameter is large. On the other hand, when "the amount of the roll-shaped noodle band m is small", the roll-shaped noodle band m has a light weight and a small winding diameter.

Hereinafter, the detailed configuration of the rotation regulating means 20 of the first embodiment will be described with reference to FIGS. 2, 3 and 4.

The rotation regulating means 20 includes a mounting plate 21 (fixing member) fixed to the side surface of the noodle band support rail 11, and a brake plate 22 (movable member) that applies a rotation regulating load to the take-up rod 10 in cooperation with the mounting plate 21. And a pull spring 23 (a urging member) for adjusting the rotation regulation load.

The mounting plate 21 is formed of a rectangular plate member, and as shown in FIGS. 3 and 4, a first step portion 21b is provided on the upper edge portion 21a, and the first lower upper surface 21c and the first upper upper surface 21d are provided. , A first rising surface 21e connecting these is formed. As shown in FIG. 2, the mounting plate 21 is screwed onto the outer surface 11b of the noodle band support rail 11 in a state where the first lower upper surface 21c is substantially flush with the upper end surface 11a of the noodle band support rail 11. It is fixed. That is, by fixing the mounting plate 21 to the noodle band support rail 11 with screws, the first step portion 21b is formed on the noodle band support rail 11.

The brake plate 22 is formed of a rectangular plate member, and as shown in FIG. 3, a second step portion 22b is provided on the upper edge portion 22a, and the second lower upper surface 22c and the second upper upper surface 22d are provided. A second rising surface 22e to be connected is formed. The brake plate 22 is superposed on the outer surface 21f of the mounting plate 21 and is connected to the mounting plate 21 via a support pin 24. At this time, the second rising surface 22e and the first rising surface 21e face each other, and a recess K for supporting the take-up rod 10 is formed between them. Further, the second lower upper surface 22c of the brake plate 22 is installed at a position higher than the first lower upper surface 21c.

The support pin 24 has a pin head 24a formed at one end thereof, and a bolt portion formed at the pin tip penetrating the mounting plate 21 and the brake plate 22 is fixed by a nut 24c via a washer 24b to prevent the support pin 24 from coming off. Has been made. The brake plate 22 can rotate relative to the mounting plate 21 around the support pin 24. Further, as shown in FIG. 2, the support pin 24 is located on the drawer side of the roll-shaped noodle band m with respect to the recess K.

As shown in FIG. 4, the pull spring 23 is a coil spring arranged on the inner side surface 21 g side of the mounting plate 21, and generates an urging force in the pulling direction (contraction direction). One end 23a of the pull spring 23 is fixed to the first mounting portion 25a provided on the mounting plate 21, and the other end 23b is fixed to the second mounting portion 25b provided on the brake plate 22. That is, the pull spring 23 is provided between the mounting plate 21 and the brake plate 22, and applies a force (tensile force) for closing the recess K by pulling up the brake plate 22. As a result, when the brake plate 22 rotates relative to the mounting plate 21 about the support pin 24, it becomes necessary to resist the tensile force of the pull spring 23.

Further, the pull spring 23 is arranged so that the recess K is located between the first mounting portion 25a and the second mounting portion 25b, and is horizontal in a state where the take-up rod 10 is not supported. It is installed like this. However, the positional relationship between the pull spring 23 and the recess K and the installation direction of the pull spring 23 are not limited to such a configuration. It suffices if the pull spring 23 is installed in a direction close to the tangential direction centered on the support pin 24 and a force for rotating the brake plate 22 can be generated. As a result, by adjusting the spring force of the pull spring 23, the pinching force of the take-up rod 10 by the brake plate 22 can be adjusted, and the pull spring 23 can hold the take-up rod 10 by the brake plate 22. It is a means of urging to adjust the force.

The first mounting portion 25a is fixed to the mounting plate 21, and the fixed portion protruding toward the brake plate 22 is located inside the second through hole 22h formed in the brake plate 22. On the other hand, the second mounting portion 25b is fixed to the brake plate 22, and the fixed portion protruding toward the mounting plate 21 is located inside the first through hole 21h formed in the mounting plate 21. Here, the first through hole 21h and the second through hole 22h are sufficiently larger than the first and second mounting portions 25a and 25b, and a gap is provided. Therefore, when the brake plate 22 is rotated, the first mounting portion 25a interferes with the inner peripheral surface of the second through hole 22h, or the second mounting portion 25b interferes with the inner peripheral surface of the first through hole 21h. This makes it possible to prevent the relative rotation of the brake plate 22 from being hindered.

Hereinafter, the detailed configuration of the rolling roll portion 30 of the first embodiment will be described with reference to FIGS. 1, 5 and 6.

The rolling roll unit 30 adjusts the rolling interval 33 by moving a pair of rolling rolls 31 and 32 for rolling the noodle strip M, first and second motors 34 and 35 for rotationally driving them, and the other rolling roll 32. The first and second roll-to-roll adjusting units 36 and 37 are provided.

That is, as shown in FIG. 1, the pair of rolling rolls 31 and 32 are arranged so as to be slanted up and down so that the rotating shaft 31a of one rolling roll 31 is higher than the rotating shaft 32a of the other rolling roll 32. Has been done. Further, the pair of rolling rolls 31 and 32 are arranged in parallel with a rolling interval 33 secured over the entire length. As a result, the rolling inlets 33a of the pair of rolling rolls 31 and 32 are opened diagonally upward so as to easily receive the noodle strip M.

Then, as shown in FIGS. 5 and 6, the pair of rolling rolls 31 and 32 are rotated by the first motor 34 and the second motor 35, respectively. Here, the first motor 34 and the second motor 35 are individually driven and controlled so that the rotation speeds of the pair of rolling rolls 31 and 32 are the same, and the rotation directions of the pair of rolling rolls 31 and 32 are set to the noodle strips, respectively. Reverse the direction so that M faces the rolling outlet 33b (see FIG. 1).

Further, the other rolling roll 32 is provided with a first inter-roll adjusting portion 36 at one end 32b of the rotating shaft 32a and a second inter-roll adjusting portion 37 at the other end 32c of the rotating shaft 32a.

The first roll-to-roll adjusting portion 36 is a mechanism for pushing and pulling one end portion 32b of the rotating shaft 32a, and has a first adjusting motor 36a, a first bracket 36b, and a first fixing portion 36c. The first adjusting motor 36a rotationally drives the first rotating shaft 36d having a male screw formed on the outer peripheral surface. The first bracket 36b connects the first adjusting motor 36a to one end 32b of the rotating shaft 32a. The first fixing portion 36c is provided inside the device housing 12 and is fixed to a frame (not shown) arranged between the first and second roll-to-roll adjusting portions 36 and 37, and the first rotating shaft 36d It has a through hole 36e that penetrates. On the inner peripheral surface of the through hole 36e, a female screw is formed in which the male screw of the first rotating shaft 36d meshes. Then, in the first roll-to-roll adjusting unit 36, the first adjusting motor 36a and the first bracket 36b are integrated with the first fixed portion 36c by rotating the first rotating shaft 36d by the first adjusting motor 36a. Move relative to. As a result, one end 32b of the rotating shaft 32a is pushed and pulled to adjust the rolling interval 33. The distance from the first fixed portion 36c to one end portion 32b of the rotating shaft 32a can be detected by a position sensor (not shown).

Further, the second roll-to-roll adjusting portion 37 is a mechanism for adjusting the horizontal position of the other end portion 32c of the rotating shaft 32a, and includes the second adjusting motor 37a, the second bracket 37b, and the second fixing portion 37c. have. The second adjusting motor 37a rotationally drives the second rotating shaft 37d having a male screw formed on the outer peripheral surface. The second bracket 37b connects the second adjusting motor 37a to the other end 32c of the rotating shaft 32a. The second fixing portion 37c is provided inside the device housing 12 and is fixed to a frame (not shown) arranged between the first and second roll-to-roll adjusting portions 36 and 37, and the second rotating shaft 37d It has a through hole 37e that penetrates. On the inner peripheral surface of the through hole 37e, a female screw is formed in which the male screw of the second rotating shaft 37d meshes. Then, in the second roll-to-roll adjusting portion 37, the second adjusting motor 37a and the second bracket 37b are integrated with the second fixed portion 37c by rotating the second rotating shaft 37d by the second adjusting motor 37a. Move relative to. As a result, the other end 32c of the rotating shaft 32a is pushed and pulled to adjust the rolling interval 33. The distance from the second fixed portion 37c to the other end portion 32c of the rotating shaft 32a can be detected by a position sensor (not shown).

By pushing and pulling the one end 32b and the other end 32c of the rotating shaft 32a, the second motor 35 that rotationally drives the rolling roll 32 moves together with the other rolling roll 32.

Here, the first adjustment motor 36a and the second adjustment motor 37a are individually driven and controlled. At this time, the pair of rolling rolls 31 and 32 are lightly brought into contact with each other, and the zero point of the position sensor (not shown) is adjusted at the position where the rolling interval 33 is set to zero. As a result, the deviation of the parallel state between the rotating shaft 31a and the rotating shaft 32a can be automatically corrected at regular intervals such as when the device is started.

Hereinafter, problems in rolling the roll-shaped noodle strip m will be described with reference to FIG. 7.

The noodle band (roll-shaped noodle band m) wound around the take-up rod 10 is formed by sequentially winding the noodle band M around the peripheral surface of the take-up rod 10. At this time, the roll-shaped noodle band m receives a stronger tightening force as the noodle band M closer to the winding center, and as shown in FIG. 7, the roll-shaped noodle band M spreads in the width direction toward the noodle band M on the winding center side. Both ends of the band m have a conical shape. Therefore, the width dimension of the noodle strip M on the winding center side may be larger than the width dimension of the pair of rolling rolls 31 and 32.

When the width dimension of the noodle strip M is larger than the width dimension of the pair of rolling rolls 31 and 32, the noodle strip M drawn between the pair of rolling rolls 31 and 32 protrudes from the rolling interval 33 and is in the width direction. Both ends may be narrowed or folded and wrinkled, making it impossible to roll properly.

Therefore, the recess K that supports the take-up rod 10 is formed in a V shape so as to gradually expand toward the opening, and the take-up rod 10 is supported by the inclined inner side surface so that the take-up rod 10 rotates. It is considered to apply a load that regulates (rotation regulation load). By applying a rotation restricting load to the take-up rod 10, when the noodle band M is pulled in by the pair of rolling rolls 31 and 32, a tension in the length direction can be applied to the noodle band M, and as a result, the noodle band M can be applied. Is known to shrink in the width direction.

However, when the take-up rod 10 is supported by the V-shaped recess K, the rotation-regulating load applied to the take-up rod 10 becomes large when the amount of the roll-shaped noodle band m is large and heavy, and the roll-shaped noodles It becomes small when the amount of band m is small and light. Therefore, when the winding rod 10 is supported by the V-shaped recess K, the rotation is restricted when the noodle band M on the winding center side, which is tightened closer to the winding center and the width of the noodle band is widened, is pulled in. The load became small, and it was difficult to apply the tension required to contract in the width direction.

Hereinafter, the winding rod supporting action of the noodle strip rolling apparatus 1 of the first embodiment will be described with reference to FIGS. 8 and 9.

In the noodle strip rolling apparatus 1 of the first embodiment, both ends of the take-up rod 10 around which the noodle strip M is wound are inserted into a slightly closed recess K of the rotation regulating means 20 provided on the noodle strip support rail 11. Then, it is placed on the second lower upper surface 22c of the brake plate 22. As a result, the brake plate 22 is pushed downward, and the brake plate 22 is rotated so as to open the recess K against the tensile force of the pull spring 23. In this way, the take-up rod 10 is installed on the noodle band support rail 11.

Here, the recess K opens wider as the amount of the roll-shaped noodle band m is larger and heavier, and gradually closes as the noodle band M is pulled out and the amount of the roll-shaped noodle band m becomes smaller and lighter. That is, when the amount of the roll-shaped noodle band m is large, the weight Fg of the roll-shaped noodle band m applied to the rotation regulating means 20 becomes large. Therefore, as shown in FIG. 8, the brake plate 22 rotates in the direction of opening the recess K around the support pin 24 against the tensile force of the pull spring 23, and the first rising surface 21e and the take-up rod 10 There is a gap between them. As a result, the pinching force F of the take-up rod 10 by the brake plate 22 does not act on the take-up rod 10, and the rotation regulation load can be reduced.

As a result of reducing the rotation regulation load, the take-up rod 10 can be smoothly rotated, and it is possible to prevent the tensile force in the length direction from acting on the noodle band M more than necessary. Further, it is possible to prevent the noodle band M from becoming too thin or breaking.

The brake plate 22 can be pushed down until the take-up rod 10 interferes with the first lower upper surface 21c. Therefore, the open state of the recess K can be adjusted by the difference in height between the second lower upper surface 22c of the brake plate 22 and the first lower upper surface 21c.

On the other hand, as the amount of the roll-shaped noodle band m decreases, the weight Fg of the roll-shaped noodle band m applied to the rotation regulating means 20 gradually decreases. Therefore, as shown in FIG. 9, the pulling force of the pull spring 23 causes the brake plate 22 to rotate in the direction of returning to the center of the support pin 24 (the direction of closing the recess K). As a result, the take-up rod 10 can be pressed by the first rising surface 21e and the second rising surface 22e, and the take-up rod 10 can be sandwiched between the brake plate 22 and the first step portion 21b of the mounting plate 21. .. As a result, the sandwiching force F of the take-up rod 10 by the brake plate 22 acts on the take-up rod 10, and as the amount of the roll-shaped noodle band m decreases, a larger rotation restricting load can be applied to the take-up rod 10. it can.

Further, the noodle strips M drawn into the pair of rolling rolls 31 and 32 have opposite lengths due to the pulling force of the noodle strips M by the pair of rolling rolls 31 and 32 and the rotation restricting load applied to the take-up rod 10. The tension in the direction acts, and the noodle band M extends in the length direction and contracts in the width direction. Then, by increasing the rotation regulation load as the amount of the roll-shaped noodle band m decreases, the width of the noodle band is appropriate even for the noodle band M on the winding center side which is widened in the width direction by receiving a strong tightening force. It can be shrunk to the desired noodle band width.

Further, the rotation regulating means 20 is wound by the brake plate 22 and the brake plate 22 that sandwich the winding rod 10 between the first step portion 21b formed on the noodle band support rail 11 and the first step portion 21b. It is provided with a pull spring 23 for adjusting the pinching force of the rod 10.

Here, the magnitude of the rotation regulation load is defined by the balance between the tensile force of the pull spring 23 and the weight Fg of the roll-shaped noodle band m that pushes down the brake plate 22. When the tensile force of the pull spring 23 is increased, the brake plate 22 cannot be pushed down unless the weight Fg of the roll-shaped noodle band m is heavier, and the rotation regulation load cannot be reduced. On the other hand, if the tension of the pull spring 23 is weakened, the brake plate 22 is pushed down even if the weight Fg of the roll-shaped noodle band m is light, and the rotation regulation load can be reduced. In other words, even if the amount of the roll-shaped noodle band m is constant, the stronger the tensile amount of the pull spring 23, the larger the rotation regulation load can be. Therefore, by adjusting the force (tensile force) for pulling up the brake plate 22 by the pull spring 23, the magnitude of the rotation regulation load applied to the take-up rod 10 can be easily controlled.

Further, in the noodle strip rolling apparatus 1 of the first embodiment, the first step portion 21b is formed on a mounting plate 21 that can be detachably attached to the noodle strip support rail 11. Further, the pull spring 23 connects the brake plate 22 to the mounting plate 21. Therefore, the rotation regulating means 20 can be attached to an arbitrary position of the noodle band support rail 11, and the position is optimal for rolling the noodle band according to the material of the noodle band M, the size of the roll-shaped noodle band m, and the like. The take-up rod 10 can be supported.

Hereinafter, the configuration and problems of the rolling roll portion of the first comparative example will be described with reference to FIG.

In the rolling roll unit 100 of the first comparative example, as shown in FIG. 10, one motor 101 rotationally drives one rolling roll 31, and the rotational force is transferred to the other rolling roll 32 via the tuning gears 102 and 103. By transmitting, the pair of rolling rolls 31 and 32 are rotationally driven. Therefore, the roll shaft dimension L1 is the sum of the lengths of the rolling rolls 31 and 32 and the thicknesses of the tuning gears 102 and 103. Further, in the rolling roll unit 100, since the pair of rolling rolls 31 and 32 are rotationally driven by the power of one motor 101, it is necessary to increase the size of the motor 101. Therefore, the axial dimension L2 of the motor 101 is also relatively long.

Further, in general, when the noodle strips M are rolled by the pair of rolling rolls 31 and 32, the pair of rolling rolls 31 and 32 try to widen the rolling interval 33 from the noodle strips M drawn into the rolling interval 33. Receives a reaction force F _{α in the} direction. Therefore, in the rolling roll portion 100, a force (radial load) F _β in the direction of pulling the gears apart is also applied to the tuning gears 102 and 103. Then, these resultant forces act as a radial load on the bearings 38a and 38b that support the pair of rolling rolls 31 and 32. For example, when the reaction force F _α received by the pair of rolling rolls 31 and 32 becomes large because the noodle band M is hard or the like, the torque required to rotate the rolling rolls 31 and 32 becomes higher. At that time, the radial load _Fβ also increases, and the radial load acting on the bearings 38a and 38b also increases. As a result, the bearings 38a and 38b that support the pair of rolling rolls 31 and 32 may be damaged, and the peeling life of the bearings 38a and 38b may be shortened.

Further, when the noodle strips M are rolled by the pair of rolling rolls 31 and 32, if the noodle strips M to be rolled are thick, it is necessary to widen the rolling interval 33. However, if the rolling interval 33 is widened in the rolling roll portion 100, the distance between the centers of the tuning gears 102 and 103 is also widened, and sufficient power transmission cannot be performed. Moreover, since the blades of the tuning gears 102 and 103 may be damaged by this, the rolling interval 33 can be widened only within the range in which the gear strength of the tuning gears 102 and 103 can be guaranteed.

Hereinafter, the rotation driving action of the pair of rolling rolls 31 and 32 of the first embodiment will be described.

In the rolling roll portion 30 of the noodle strip rolling apparatus 1 of the first embodiment, each of the pair of rolling rolls 31 and 32 is rotationally driven individually by the first motor 34 and the second motor 35. Therefore, in this rolling roll portion 30, the tuning gears 102 and 103 can be eliminated, and the roll shaft dimension La (roll shaft dimension La () is equal to the thickness of the tuning gears 102 and 103 as compared with the roll shaft dimension L1 of the rolling roll portion 100. (See FIG. 6) can be shortened. Further, since the first and second motors 34 and 35 rotate and drive the rolling rolls 31 and 32 one by one, for example, a small motor having an output about half that of the motor 101 used in the rolling roll unit 100 is applied. It becomes possible. As a result, the axial dimension Lb (see FIG. 6) of the first and second motors 34 and 35 can also be shortened as compared with the axial dimension L2 of the motor 101 of the rolling roll portion 100. Therefore, the noodle strip rolling apparatus 1 of the first embodiment can be made shorter in the roll axis direction than the rolling roll portion 100 of the first comparative example, and the entire apparatus can be miniaturized.

Further, in the noodle strip rolling apparatus 1 of the first embodiment, the radial load F _β is not generated by eliminating the need for the tuning gears 102 and 103. Therefore, it is possible to suppress the radial load acting on the bearings 38a and 38b and extend the peeling life of the bearings 38a and 38b.

Further, in the noodle strip rolling apparatus 1 of the first embodiment, since the tuning gears 102 and 103 are unnecessary, the rolling interval 33 can be adjusted without considering the tooth engagement of the tuning gears 102 and 103. Moreover, in the rolling roll portion 100, when the rolling interval 33 is widened, the backlash of the tuning gears 102 and 103 is widened, which causes a problem that the interference noise of the teeth is increased. However, since the noodle strip rolling apparatus 1 of the first embodiment does not have the tuning gears 102 and 103 in the first place, quietness can be ensured regardless of the size of the rolling interval 33.

In general, in a noodle strip rolling apparatus, when a difference in rotation speed occurs between a pair of rolling rolls, the surface of the noodle strip M during rolling may be roughened, and in some cases, the noodle strip M may be torn. Are known. This phenomenon often occurs when the diameter dimensions of the pair of rolling rolls are different (one roll diameter is large), which has been a problem. However, in the noodle strip rolling apparatus 1 of the first embodiment, the rotation control of the pair of rolling rolls 31 and 32 is individually performed by the independent first and second motors 34 and 35. Therefore, for example, even if the rotation speed of one of the rolling rolls is high, the rolling roll having a high rotation speed is loaded and stalls. Therefore, the difference in rotation speed naturally converges, and it is possible to prevent the noodle band M from becoming rough or torn.

Hereinafter, the configuration and problems of the rolling roll portion of the second comparative example will be described with reference to FIG.

As shown in FIG. 11, the rolling roll portion 200 of the second comparative example is provided with worm gear units 201 and 202 at both ends of the rotating shaft 32a of the other rolling roll 32, respectively, and each of these worm gear units 201 and 202 is provided. The handle shaft 204 of the handle 203 is connected to.

Then, in the rolling roll unit 200, the handle 203 is manually rotated to drive the worm gear units 201 and 202, respectively, via the handle shaft 204. As a result, the two rolling rolls 201 and 202 are pushed and pulled to adjust the rolling interval 33. The motor shaft of the motor 205 may be connected to the worm gear units 201 and 202 to electrically adjust the rolling interval 33.

Here, when the rolling interval 33 is adjusted, if the parallel states of the rotating shafts 31a and 32a are deviated, the thickness of the rolled noodle strip M is not uniform and the noodle making quality is deteriorated. Therefore, it is necessary to maintain the parallel state of the rotating shafts 31a and 32a of the pair of rolling rolls 31 and 32.

However, in the rolling roll portion 200, there arises a problem that the rotating shafts 31a and 32a are not parallel due to the deviation of the worm gear units 201 and 202 and the handle shaft 204, the bending of the handle shaft 204, and the like.

Hereinafter, the interval adjusting action of the pair of rolling rolls 31 and 32 of Example 1 will be described.

In the rolling roll portion 30 of the noodle strip rolling apparatus 1 of the first embodiment, a first roll-to-roll adjusting portion 36 is provided at one end portion 32b of the rotating shaft 32a of the other rolling roll 32, and the other end portion 32c of the rotating shaft 32a is provided. Is provided with a second roll-to-roll adjusting unit 37. As a result, the driving force can be input to both ends 32b and 32c of the rotating shaft 32a, respectively.

Therefore, the rotating shaft 32a can be moved while being parallel to the rotating shaft 31a. Further, the zero point of the position sensor (not shown) is adjusted with the pair of rolling rolls 31 and 32 in contact with each other, and the position sensor monitors the positions of both ends 32b and 32c of the rotating shaft 32a to rotate the rolling rolls 31 and 32. It is possible to prevent the occurrence of deviation of the parallel state of the shaft 32a. In particular, by periodically adjusting the zero point of the position sensor when the device is started, it is possible to suppress the collapse of the parallel state due to the initial assembly accuracy and vibration during use of the rolling rolls 31 and 32, and the parallel state. Maintenance accuracy can be improved.

(Example 2)
In the noodle strip rolling apparatus 1A of the second embodiment, the noodle strip support rail in which the step portion 13 of the rotation regulating means 40 for supporting the winding rod 10 around which the noodle strip M is wound is an installation portion provided with the rotation regulating means 40. It is an example formed in 11. The noodle strip rolling apparatus 1A of the second embodiment also includes a pair of rolling rolls (not shown). However, since the pair of rolling rolls of Example 2 has the same configuration as that of Example 1, description thereof will be omitted here.

As shown in FIG. 12, the rotation regulating means 40 of the noodle band rolling apparatus 1A of the second embodiment is provided on the gutter-shaped noodle band support rail 11 (installation portion). Here, the step portion 13 is provided on the upper edge portion 11α of the noodle band support rail 11. Since the stepped portion 13 is provided, the upper edge portion 11α of the noodle band support rail 11 has a first lower upper surface 13a, a first upper upper surface 13b, and these, as shown in FIGS. 13 and 14. A first rising surface 13c is formed to connect the two.

As shown in FIGS. 13 and 14, the rotation regulating means 40 of the second embodiment has a fixing plate 41 fixed to the side surface of the noodle band support rail 11 and a take-up rod 10 in cooperation with the noodle band support rail 11. It is provided with a brake plate 42 (movable member) that applies a rotation restricting load to the vehicle, and a pull spring 43 (a urging member) that adjusts the rotation restricting load.

The fixing plate 41 is formed of a rectangular plate member, and as shown in FIGS. 13 and 14, the noodles are in a state where the upper end surface 41a is substantially flush with the first lower upper surface 13a of the noodle band support rail 11. It is screwed to the outer surface 11b of the band support rail 11.

The brake plate 42 is formed of a rectangular plate member, and as shown in FIG. 13, a second step portion 42b is provided on the upper edge portion 42a, and the second lower upper surface 42c and the second upper upper surface 42d are provided. A second rising surface 42e to be connected is formed. The brake plate 42 is overlapped with the outer surface 41f of the fixing plate 41 and is connected to the fixing plate 41 via a support pin 44. At this time, the second rising surface 42e and the first rising surface 13c face each other, and a recess K for supporting the take-up rod 10 is formed between them. Further, the second lower upper surface 42c of the brake plate 42 is installed at a position higher than the upper end surface 41a of the fixing plate 41 and the first lower upper surface 13a of the noodle band support rail 11.

The support pin 44 has a pin head 44a formed at one end thereof, and a bolt portion formed at the pin tip penetrating the fixing plate 41 and the brake plate 42 is fixed by a nut 44c via a washer 44b to come off. It has been stopped. The brake plate 42 can rotate relative to the fixing plate 41 around the support pin 44. Further, as shown in FIG. 12, the support pin 44 is located on the drawer side of the roll-shaped noodle band m with respect to the recess K.

As shown in FIG. 14, the pull spring 43 is a coil spring arranged on the inner side surface 41 g side of the fixing plate 41, and generates an urging force in the pulling direction (contraction direction). One end 43a of the pull spring 43 is fixed to the first mounting portion 45a provided on the fixing plate 41, and the other end 43b is fixed to the second mounting portion 45b provided on the brake plate 42. That is, the pull spring 43 is provided between the fixing plate 41 and the brake plate 42, and applies a force (tensile force) for closing the recess K by pulling up the brake plate 22. As a result, when the brake plate 42 rotates relative to the fixing plate 41 about the support pin 44, it becomes necessary to resist the tensile force of the pull spring 43.

Further, the pull spring 43 is arranged so that the recess K is located between the first mounting portion 45a and the second mounting portion 45b, and is horizontal in a state where the take-up rod 10 is not supported. It is installed like this. As a result, by adjusting the spring force of the pull spring 43, the pinching force of the take-up rod 10 by the brake plate 42 can be adjusted, and the pull spring 43 can hold the take-up rod 10 by the brake plate 42. It is a means of urging to adjust the force.

The first mounting portion 45a is fixed to the fixing plate 41, and the fixing portion protruding toward the brake plate 42 is located inside the second through hole 42h formed in the brake plate 42. On the other hand, the second mounting portion 45b is fixed to the brake plate 42, and the fixing portion protruding toward the fixing plate 41 is located inside the first through hole 41h formed in the fixing plate 41. Here, the first through hole 41h and the second through hole 42h are sufficiently larger than the first and second mounting portions 45a and 45b, and a gap is provided. Therefore, when the brake plate 42 is rotated, the first mounting portion 45a interferes with the inner peripheral surface of the second through hole 42h, or the second mounting portion 45b interferes with the inner peripheral surface of the first through hole 41h. This makes it possible to prevent the relative rotation of the brake plate 42 from being hindered.

Hereinafter, the winding rod supporting action of the noodle strip rolling apparatus 1A of the second embodiment will be described with reference to FIGS. 15 and 16.

In the noodle strip rolling apparatus 1A of the second embodiment, when the take-up rod 10 in which the noodle strip M is wound by the rotation regulating means 40 is supported, both ends of the take-up rod 10 are placed in the recesses K of the rotation regulating means 40. It is inserted and placed on the second lower upper surface 22c of the brake plate 42.

At this time, when the amount of the roll-shaped noodle band m is large and heavy, the weight Fg of the roll-shaped noodle band m applied to the rotation regulating means 40 becomes large. Therefore, as shown in FIG. 15, the brake plate 42 rotates around the support pin 44 in the direction of opening the recess K against the tensile force of the pull spring 43, and the first rising surface 13c and the take-up rod 10 There is a gap between them. As a result, the pinching force F of the take-up rod 10 by the brake plate 42 does not act on the take-up rod 10, and the rotation regulation load can be reduced.

On the other hand, as the amount of the roll-shaped noodle band m decreases, the weight Fg of the roll-shaped noodle band m applied to the rotation regulating means 40 gradually decreases. Therefore, as shown in FIG. 16, the pulling force of the pull spring 43 causes the brake plate 42 to rotate in the direction of returning to the center of the support pin 44 (the direction of closing the recess K). As a result, the take-up rod 10 can be pressed by the first rising surface 13c and the second rising surface 42e, and the take-up rod 10 can be sandwiched between the brake plate 42 and the stepped portion 13 of the noodle band support rail 11. .. As a result, the sandwiching force F of the take-up rod 10 by the brake plate 42 acts on the take-up rod 10, and as the amount of the roll-shaped noodle band m decreases, a larger rotation restricting load can be applied to the take-up rod 10. it can.

As described above, also in the noodle band rolling apparatus 1A of the second embodiment, the sandwiching force F of the winding rod 10 by the brake plate 42 is changed according to the winding amount of the roll-shaped noodle band m, and the roll-shaped noodle band m When the amount of the roll-shaped noodle band m is large, the rotation-regulating load that regulates the rotation of the take-up rod 10 can be made larger than when the amount of the roll-shaped noodle band m is large. Thereby, the noodle band M drawn between the pair of rolling rolls (not shown here) can be shrunk to an appropriate noodle band width and adjusted to the desired noodle band width.

Further, in the rotation regulating means 40 of the second embodiment, a step portion 13 is formed on the noodle band support rail 11 which is an installation portion. This makes it possible to support the take-up rod 10 by utilizing the existing structure.

Although the noodle strip rolling apparatus of the present invention has been described above based on Examples 1 and 2, the specific configuration is not limited to these Examples, and each claim in the claims is limited to these examples. Design changes and additions are permitted as long as they do not deviate from the gist of the invention.

In the first embodiment, the first rising surface 21e stands in a direction orthogonal to the first lower upper surface 21c and the first upper upper surface 21d, and the second rising surface 22e stands on the second lower upper surface 22c and the second. An example of standing upright in a direction orthogonal to the upper upper surface 22d is shown. However, it is not limited to this. For example, the first and second rising surfaces 21e and 22e may be inclined so that the recess K gradually expands toward the opening.

Further, in the first and second embodiments, as an urging member for adjusting the pinching force F of the take-up rod 10 by the brake plates 22 and 42 (movable members), the pull springs 23 and 43 made of coil springs are used. Although shown, it is not limited to this. Since it may be an urging member that pulls the brake plates 22 and 42 (movable members) in a direction that prevents rotation, for example, a pull-type hydraulic cylinder or rubber may be used.
