Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a noodle rolling device equipped with a roll gap adjustment mechanism, and particularly relates to a noodle rolling device equipped with a roll gap adjustment mechanism, and in particular, a noodle rolling device that pivots two supports that individually support two rolls. The roll gap can be adjusted by relative pivoting of the supports, and a screw is installed between both supports on the opposite side of the roll axis surface from the pivot position, and the rotation of the screw adjusts the roll gap. Pivoting the support simplifies the structure of the roll gap adjustment mechanism, reduces the force required for adjustment, and allows for fine adjustment.

[Conventional example]

As a conventional noodle rolling device, there is one shown in FIGS. 1 and 2. That is, FIG. 1 is a side view of the same rolling apparatus, and the U-shaped part 2 of the machine body 1 includes a first support 3 that supports the first roll R1 and a second support that supports the second roll R2. The body 4 is engaged. The U-shaped part 2 is also formed on the opposite side of the fuselage 1, in which also a first support 3 and a second support 4 are engaged, so that a first support 3 and a second support 4 are engaged between the two first supports 3. One roll R1 is mounted on an axis, and a second roll R2 is similarly mounted on an axis between two second supports 4.

The first support 3 is at the bottom of the U-shaped part 2, above which the second support 4 is arranged. The upper part of the U-shaped portion 2 consists of two parallel surfaces 2a and 2b facing each other, and the front and rear surfaces 4a and 4b of the second support 4 are also parallel, and the second support 4 is formed by the U-shaped portion 2. To,
It is slidable along parallel surfaces 2a and 2b. Further, an elastic body 5 is interposed between the first support body 3 and the second support body 4, and as the elastic body 5 is elastically deformed, the second support body 4 slides. be.

6 is a roll axis that is the center line of the first roll R1, and 7 is a roll axis that is the center line of the second roll R2. Therefore, the roll axes 6, 7 2
A plane including two straight lines is the roll axis surface 8.

A frame 9 is fixed to the upper side of the body 1, and two screws 10 made of hexagonal bolts are passed through this frame. The tip of each screw 10 has two second
Each of the screws 10 is in contact with the upper surface of the support 4, and a worm wheel 11 is screwed into the middle of both screws 10. The boss of the worm wheel 11 is supported by a thrust bearing 12 on the inner surface of the frame 9, and prevents the worm wheel 11 from rising along the screw 10.

The worm wheel 11 meshes with the worm 13, and the worm 13 is fixed to the rotating shaft 14. The rotating shaft 14 is mounted between face plates 15 fixed to the frame 9, and a handle 16 is fixed to one end thereof.

A spur gear 17 is fixed to the screw 10, and a stopper 18 meshes with the spur gear 17. The stopper 18 has teeth that mesh with the spur gear 17 like a rack, and is turned by the handle 19 to engage and disengage from the spur gear 17, and this engagement prevents the screw 10 from rotating. It's like this.

The roll gap of such a rolling machine is adjusted as follows. That is, stopper 18
The screw 10 is rotated with the screw removed from the spur gear 17. This rotation is performed by engaging the bolt head with a wrench or the like, and while compressing the elastic body 5 of the second support body 4 in the direction of the first support body 3 at the tip of the screw 10, the second roll R2 Press it down until it comes into contact with roll R1 and there is no roll gap.

Then, in a state where the first roll R1 and the second roll R2 are in contact with each other over the entire longitudinal direction, the handle 19 is turned to engage the stopper 18 with the spur gear 17, thereby suppressing the rotation of the screw 10. Next, by rotating the handle 16, the worm wheel 1 is rotated through the rotation shaft 14 and the worm 13.
Rotate 1. Since the upper side of the worm wheel 11 is supported by the frame 9 via the thrust bearing 12, the worm wheel 11 does not rise even when it rotates, but pushes up the screw 10 screwed into the center of the worm wheel 11.

When the screw 10 rises, the force pushing down the second support 4 is released, so the second support 4 is pushed up by the elastic restoring force of the elastic body 5. Since the amount of movement of this second support 4 is proportional to the rotation speed of the rotating shaft 14, the amount of movement of the two second supports 4 is equal, so the roll gap between the first roll R1 and the second roll R2 is R1 and R2 are equal in the longitudinal direction. When the handle 16 reaches a predetermined rotation speed, the roll gap is adjusted to a predetermined size.

However, in such conventional rolling equipment, the second support 4 has to be slidably disposed between the parallel surfaces 2a and 2b of the U-shaped portion 2 as a mechanism for adjusting the roll gap. , the parallel surfaces 2a and 2b must be machined with high precision, and the surfaces 4a and 2b of the second support 4 that fit therewith must be machined with high precision.
4b also needed to be processed with high precision, so
There was a problem that the manufacturing process was troublesome and the cost was high.

Further, according to the conventional example, since the screw 10 is arranged on the extension of the roll axis surface 8, it is necessary to directly apply the force necessary for moving the second support 4 to the screw 10. There was a problem that the driving force required to move the support 4 was large.

[Purpose of the invention]

This invention was made in order to solve the problems of the conventional example, and its purpose is to simplify the structure and processing process of the roll gap adjustment mechanism and reduce the cost of the rolling equipment. Further, the purpose is to facilitate the work of adjusting the roll gap.

[Structure of the invention]

Next, the structure of the present invention will be explained with reference to the symbols attached to the illustrated embodiments. The body 3 and the second support body 4 that supports the other second roll R2 are pivotally connected at a position apart from the roll axis surface 8 to make the roll gap variable, and This noodle rolling device is characterized in that a screw 10 for adjusting the roll gap is installed between both supports 3 and 4 on the opposite side to the landing position.

〔Example〕

The present invention will be explained below based on the embodiments shown in FIG. 3 and below.

FIG. 3 is a side sectional view of this embodiment, and FIG. 4 is a sectional view taken along the line -- in FIG. Reference numeral 3 denotes first supports, which are arranged on the left and right sides, and a first roll R1 is rotatably installed between the two first supports 3. 20 is a rotating shaft of the first roll R1, and the rotating shaft 20 and the first roll R1 are keyed together. A bearing 33 and a sealing material 34 are arranged between the rotating shaft 20 and the first support 3.
3 is covered with a cover 33. Furthermore, flanges 21 that rotate together with the first roll R1 are fixed to both end surfaces of the first roll R1.

A second support 4 is pivotally attached to the two first supports 3 at their upper ends by pins 22, respectively. This state is shown in detail in FIG. 5, in which 22a is the head of the pin 22, 2
7, 28, 29 are washers, 30, 31 are bushes, and 32 is a retaining bolt.

A second roll R2 is provided between the two second supports 4.
is installed so that it can rotate freely. 23 is a rotating shaft of the second roll R2, and the rotating shaft 23 and the second support body 4
A bearing 36 and a sealing material 37 are arranged between them, and the bearing 36 is covered with a cover 38.

The first roll R1 and the second roll R2 form a pair to form a rolling mechanism, and therefore the rotating shafts 20, 2
A roll axis surface 8 is formed between the roll axes 6 and 7, which are the center lines of each roll. The second support 4 on which the second roll R2 is installed is pivotally connected to the first support 3 by the pin 22 as described above, and the second support 4 is pivotable. By this pivoting, the roll gap between the first roll R1 and the second roll R2 can be changed.

Further, at a position opposite to the pin 22 via the roll axis surface 8, a first
A screw 10 is provided between the support 3 and the second support 4.
is passed over. The screw 10 is made of a bolt, and a cap nut 24 is screwed into the end thereof, and a lever 25 for rotating the cap nut 24 is installed on the cap nut 24. A rubber-like elastic body 26 is interposed between the first support body 3 and the second support body 4 so as to surround the screw 10.
Reference numeral 6 biases the distance between the first support 3 and the second support 4 in a direction that constantly increases the distance between the first support 3 and the second support 4.

Thus, when the cap nut 24 is tightened by the lever 25, the rubber-like elastic body 26 is compressed and the second support 4 is pivoted in the direction closer to the first support 3.
When the cap nut 24 is loosened, the elastic restoring force of the rubber-like elastic body 26 causes the second support body 4 to be moved to the first support body 3.
It is configured to be pivoted in a direction away from.

In this embodiment, the center of the pin 22 and both rolls R
1. The R2 contact position and the center of the screw 10 are the third
In the figure, the rollers R1 and R2 are positioned so that they form a straight line, and the contact position of both rolls R1 and R2 is at a position that bisects the distance between the center of the pin 22 and the center of the screw 10.

One end of each of the rotating shafts 20 and 23 extends outward from the first support 3 and the second support 4, and gears 39 and 40 are fixed thereto. Gears 39, 4
0 are in mesh with each other, and the rotating shaft 20 is further extended, and the extended end thereof is connected to a motor serving as a driving source.

Further, a peeling plate 41 is in elastic contact with the lower outer peripheral position of the first roll R1. Peeling plate 41
is the support plate 4 fixed to the bracket 42.
3, and the bracket 42 is rotatably fitted onto a horizontal bar 44 installed between the left and right first supports 3. The bracket 42 is urged by a spring (not shown) to rotate clockwise in FIG. 3, and as a result, one side of the peeling plate 41 is always in elastic contact with the first roll R1. It is designed to peel off noodle flour, etc. that has adhered to the outer periphery of the plate.

The above-mentioned rolling devices are used in such a way that a plurality of rolling devices are lined up in a row, and the noodles pass through them sequentially while being rolled by each rolling device. A bracket 45 is fixed to the lower side of the left and right first supports 3, respectively.

A pair of roll cutters 46 and 47 are hung between the left and right brackets 45. The roll cutters 46 and 47 form a large number of annular grooves at predetermined intervals on the outer periphery of the roll to form unevenness in the axial direction.
It is made by interlocking the unevenness of two rolls, and is used to form noodle strings by vertically cutting the noodles passed between the first roll R1 and the second roll R2, and is known per se. It is. The roll cutters 46, 47 are connected to the rotation shaft 20 of the first roll R1 via a transmission device (not shown), so that the rotation of the rotation shaft 20 causes the roll cutters 46, 47 to rotate. Further, the meshing dimensions of the roll cutters 46 and 47 can be adjusted by allowing these bearings to move along the guide 45a of the bracket 45.

Next, the operation of this device will be explained.

The roll gap is adjusted only by rotating the cap nut 24. That is, first, the cap nut 24 is tightened, and the second support body 4 is pivoted about the pin 22 in a direction to bring the second support body 4 closer to the first support body 3 while compressing and deforming the rubber-like elastic body 26. Roll R1
The roll gap between the roll R2 and the second roll R2 is set to 0.

Next, the cap nut 24 is rotated in the opposite direction to loosen it, and the pin 22 is moved in a direction that separates the second support body 4 from the first support body 3 due to the elastic restoring force of the rubber-like elastic body 26.
Pivot around. Then, as the second support body 4 pivots, the second roll R2 separates from the first roll R1, and the roll gap becomes larger than zero.

Since the roll gap at this time is proportional to the rotation angle of the cap nut 24, the relationship between the rotation angle and the roll gap is experimentally determined in advance, and the cap nut 24 is rotated by the rotation angle corresponding to the desired roll gap. By doing so, the roll gap is set to a desired size. The rotation angle of the cap nuts 24 at this time is the same for each of the cap nuts 24 of the left and right screws 10. This results in the same roll gap in the axial direction.

In addition, in order to rotate the left and right cap nuts 24 at the same time and make the rotation angles the same, it is also possible to extend a rotating shaft between the left and right cap nuts 24 and interlock both cap nuts 24 using a bevel gear, a worm gear, etc. It is possible.

Adjustment of the roll gap based on the rotation of the cap nut 24 requires relatively little force. That is, on the opposite side of the roll axis surface 8 from the center of the pin 22,
A screw 10 for adjusting the roll gap is installed between both supports 3 and 4, and both rolls R are installed at a position that bisects the distance between the center of the pin 22 and the center of the screw 10.
1, R2 is positioned so that there is a contact position. Therefore, the distance between the fulcrum (center of pin 22) and the point of force (center of screw 10) is
center) and point of action (position of contact between both rolls R1 and R2)
The distance between the screw 10 and the rubber-like elastic body 2 is approximately twice as large as that of the
The force that 6 must support is significantly reduced to about one-half compared to the conventional one.

As mentioned above, when the first roll R1 and the second roll R2 move relative to each other due to the adjustment of the roll gap, the relative positions of the gears 39 and 40 also change, but if the amount of change is the adjustment of the thickness of the noodles, Because of its small size,
There is relative movement of both rolls within the range in which the gears 39, 40 are maintained in mesh. In addition, when the relative movement amount of both rolls is large, the rotating shafts 20, 2
If a universal joint is interposed in the portion of No. 3 near the gears 39 and 40, both rolls can be moved significantly while ensuring meshing of the gears 39 and 40.

The noodles are rolled by passing through the roll gap adjusted in this manner from the upper right to the lower left in FIG. 3. The noodles immediately after rolling are roll cutlets 46,4
7, where it is formed into noodle strings and sent to the next process. In the first roll R1, the noodle flour etc. that adhered to the outer periphery during rolling are removed from the peeling plate 41.
scraped off by Noodle flour and the like adhering to the second roll R2 are also peeled off by means not shown.

Note that in this embodiment, the first roll R1
The first support 3 supporting the second roll R2 and the second support 4 supporting the second roll R2 are directly pivotally connected by pins 22, but there is no space between the first support 3 and the second support 4. Of course, another member may be interposed, and both supports 3 and 4 may be indirectly pivotally connected via that member. In addition, the screw 10 of this embodiment does not rotate, and the cap nut 24 screwed into it does not rotate.
is supposed to rotate, but screw 10
The first support body 3 and the second support body 4 may be pivoted relative to each other by rotating.

〔Effect of the invention〕

As explained above, according to the present invention, the first
A first support that supports the roll and a second support that supports the second roll are pivotally connected at a position apart from the roll axis plane, and the relative pivot between the first support and the second support is determined. Since the roll gap can be adjusted by movement, the troublesome work of forming two sets of two parallel surfaces, as in the conventional example shown in FIG. 1, is no longer necessary when manufacturing the device. This has the effect of simplifying manufacturing and reducing costs. Further, in this invention, since a screw for adjusting the roll gap is installed between both supports on the opposite side of the roll axis surface from the pivot position, the roll gap can be adjusted by applying the lever principle. The force for adjustment and the force supporting the reaction force during rolling are significantly reduced. For this reason,
The ease of adjusting the roll gap is ensured, and
The screw can be made smaller, which also contributes to reducing manufacturing costs. Further, according to the invention, a pair of rolls, respective supports,
Pins for pivotally mounting the support body and screws are essential parts, and the number of parts can be significantly reduced. This simplifies the structure, which also has the effect of making it possible to downsize the device and reduce costs.
