2. Description of the Related Art As shown in FIG. 9, dumpling skin, wonton dough, etc. are generally 0.8 mm in a roller type rolling machine 62 while extruding a mixed raw material in which wheat flour, saline solution, etc. are premixed by an extruder 61. A method of making noodle strips having a certain thickness and punching them into a predetermined size by a punching machine 63 is used.

[0003]

Generally, the above-mentioned leather dough is not rectangular but round, so if the strip-shaped noodle materials are punched out at a predetermined interval, the portion between them becomes the residual skin and is not thrown away. It is economical, and when it is regenerated, there is a problem that it takes extra time and the taste is deteriorated. Also, in terms of raw materials, it was not possible to freely select the type of flour or the like due to these physical properties. Further, since the rollers are rolled for a long time in the same direction, the rolling direction is constant, and there is no tension in the dough in the direction perpendicular to the rolling direction, which weakens and there is a problem that it breaks during the work of bending the skin and packing the contents.

Further, the outer peripheral portion of the leather material is thicker than the central portion because the two outer peripheral portions are joined together, and the texture is not favorable.
Then, in order to solve these problems, there is a problem that the efficiency is not improved and the cost is increased when the individual molding is performed one by one manually. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a method and a molding method for automatically and continuously molding a hand-made leather material with a machine easily and continuously. It is intended to provide a device.

[0005]

In order to achieve the above-mentioned object, the present invention places a dough ball for one kneaded raw material dough on the center of a rotatable first disk, A material that presses the raw material with a freely rotatable second disk that is eccentric and inclined with respect to the disk, and rotates the first disk around the second disk to extend the material into a disk shape and gradually thin the outside. Is what makes Further, a rotor rotatably supported by the main body 1, a first drive means for rotationally indexing the rotor, and a rotary shaft rotatably rotatably supported by the rotor at a position corresponding to the indexing angle. A first disc member concentrically provided on each shaft end, a second driving means for rotating the first disc member, and an eccentric and inclined eccentric member with respect to the first disc member indexed to the dough ball receiving position. And a rotatable second disc member that can come into contact with and separate from the first disc at the dough ball receiving position.
It comprises means for supplying a ball of dough onto the disk member and means for stripping off the leather cloth adhering to the first disk member at the leather cloth discharge position, and the outer side is provided by rotation of the first disk member and the second disk member. Is a disc-shaped leather material that becomes thinner in sequence. The second drive means includes an acceleration adjusting means for smoothly increasing the rotational acceleration at the start of dough ball rolling, and at the intermediate position between the dough ball feeding position and the leather dough discharging position, the leather on the first disc member is It is desirable to interpose a means for sprinkling the dough with flour.

[0006]

[Action]

Claims 1 and 2 transfer the dough balls sent by the conveyor to the center of the lower first disk by means of dough ball insertion means, lower the second disk above and press the dough balls. When the lower first disc is rotated, the upper second disc turns around and the dough balls are rolled in the spiral direction to form a round leather dough having a thick central portion and a thin outer periphery. Claim 3 Since the dough ball is not suddenly stretched because it is gradually accelerated by the accelerating means during rolling, it is rolled into a perfect circle. According to a fourth aspect of the present invention, when the dust powder sent by the electromagnetic feeder at the 90 ° rotation position of the rotor is applied to and collected on the surface of the skin material attached to the rotating first disk, the skins do not stick to each other.

[0007]

It is most preferable that the center of eccentricity is located in the second quadrant in terms of roundness of the forming material, rolling efficiency, and prevention of adhesion to the upper disc.

Further, the upper disk 19 is tilted at a slight angle θ so that the outer circumference can contact on the eccentric side. Then, these adjustments are performed by adjusting the tilt angle θ of the rotating shaft above and below the bracket 14.
The eccentric amount and the eccentric position can be changed by changing the position of the bracket 18 from the turning shaft 13 and the position of the arm 16 in the turning shaft 13 in the axial direction. An arm 23 is fixed to an end of the swivel shaft 13 protruding from the bracket 14, and is pivotally connected to an end of a piston rod 26 of an air actuator 24 provided in the main body 1 so that the arm 23 can swivel around the swivel shaft 13. Yes, by changing the operating pressure of the air actuator 24, the pressing force of the dough ball on the upper disk 19 can be changed.

A belt conveyor 27 having a conveyance surface on the same plane as the disk 8a at the dough ball supply position in the upper portion conveys the dough ball made by an extruder described later in parallel with the rotor shaft. The speed of the belt conveyor 27 is determined according to the speed produced by the extruder and is intermittently fed, but the dough ball position on the conveyor is made to coincide with the arrangement interval of the lower disks 8a. A dough ball insertion plate 28 having recesses 28a having the same pitch as the number of lower disks arranged and the pitch in the axial direction is arranged in parallel with the conveyor 27. This plate is an air actuator horizontally provided in the main body 1. It is attached to the end of the piston rod 31 of 29 and is provided so as to be able to move forward and backward. A receiving plate 32 for guiding the dough balls when the dough balls are inserted is attached between the conveyor 27 and the lower disk 8a.

Further, a dusting box 33 is attached to the electromagnetic feeder 34 at a position facing the disk 8b at a position 90 ° away from the rolling position. The front side plate of the dust collecting box 33 is made of a thin diaphragm 36 having an open bottom, and is resonated with respect to the longitudinal vibration of the dust collecting box 34 by the electromagnetic feeder 34. And below the bottom opening is a disk 8
A flat brush 37 that rubs against b is attached. Furthermore, the main body 1 is provided on the side of the disk 8c which is 90 ° apart and faces downward.
Is provided with a horizontal air actuator 38, and a stripping plate 41 is fixed to the end of the piston rod 39. There are two scrapers 42 at the tip of the stripping plate 41.
The scraper 42 is brought into contact with the disk 8c with an appropriate contact pressure by a coil spring 44 which is attached by a bolt 43 and is interposed in the bolt. A belt conveyor 46 that receives and collects the stripped leather material is provided directly below the disk 8c facing downward.

Next, an extruder for making dough balls will be briefly described with reference to FIG. Two screws 52 are juxtaposed in a drum 51 having a raw material supply port 51a, which is a known twin-screw extruder, and are rotated by a driving unit 53. A molding die 54 having a discharge port is provided at the tip of the drum 51, and a cutter 57 having a cutting blade vertically moved by an air actuator 56 is provided on the front surface of the die exit. By adjusting the time of vertical movement of the cutter 57, the thickness of the dough ball, that is, the weight, is determined.

The process for producing the leather material of the present invention having such a structure will be described. Wheat flour, salt, and water are supplied quantitatively from the supply port 51a of the twin-screw extruder, and the screw 52
Is rotated at a predetermined number of revolutions to knead, the raw material is discharged from a molding die 54 at the outlet, pressurized air is sent to an air actuator 56, and the discharged raw material is cut by a cutter 57. A dough ball having a size (weight) determined by the set stop time at each of the upper position and the lower position of the cutter 57 is produced when the cutter moves downward and upward. The dough ball has a diameter of 15 to 30 mm, a height of 3 to 10 mm, and a weight of 3 to 7 g. The cut dough balls are arranged on the belt conveyor 27 and are intermittently sent to the supply position.

On the other hand, after the rolling work is finished, the upper disk 19 is opened by turning the turning shaft 13 by the operation of the air actuator 24 (a virtual line in FIG. 3) and stands by at the position. When three dough balls are fed to the feeding position in this example, the air actuator 29 is actuated and the dough ball insertion plate 28 is moved forward to slip the dough balls into each of the recesses 28a and slide on the guide plate 32 to stop. It is transferred to the center of the lower disk 8a. The dough ball entry plate 28 suddenly retracts, and the air actuator 24
Is operated to rotate the upper disk 19 downward and rotate the lower disk 8a.
Press the dough ball above. Since the motor 11 is rotated and the lower disk 8a is rotated, the upper disk 19 is entangled around the pressed raw material. At the start of rolling, the acceleration adjusting inverter device smoothly accelerates and rotates the motor 8 based on the set maximum frequency and the set value of the time to reach it.

The center of rotation 02 of the upper disc 19 is the lower disc 8
Since it is eccentric with respect to the rotation center O _{1 of} a, the raw material is stretched by the upper disk 19 in the spiral direction toward the outer peripheral direction. Further, since the rotary shaft 17 is inclined by θ °, the gap between the upper and lower discs is narrowed from the center to the outer peripheral side, so that the molding material is thinned on the outer peripheral side like this gap. The rolling thickness depends on the pressing time of the upper disc and the air cylinder 24.
It can be changed by the pressing force of. When the rolling for a predetermined time is completed, the rotation of the motor 11 is stopped, and the operation of the air actuator 24 causes the upper disk 19 to wait upward. On the other hand, the disk 8a to which the motor 4 is driven and the rotor 2 is rotated by 90 ° and the index leather material is attached faces directly to the side. The disk 8d is indexed to the supply position.

Up to this point, three dough balls on the conveyor 27 have been sent to the supply position, and the dough balls are transferred onto the disk 8d by the dough ball entry plate 28, and the next rolling is started in the same manner. To be done. The electromagnetic feeder 34 is activated and the dust container 3
3, the vibrating plate 36 is vibrated and the powder container box 33 vibrating plate 36
Is vibrated, the dust is sent from the opening under the vibrating plate onto the brush 37 without boring, and the dust is applied to the forming leather material on the rotating disc 8a, and the lower disc stops at the end of rolling. To be done. When the rotor is rotated 90 ° by the motor 4 in the same manner after the rolling is finished, the disk 8a, on which the powdered dough is coated with dust, is positioned downward. After the lower disk is rotated and the rolling is started, the air actuator 38 is actuated and the scraper 42 is advanced to peel off the molded leather material on the disk 8a. The stripped molded leather material falls on the conveyor 46 and is collected.

Experimental Example 1 ○ Raw material conditions: Semi-strong powder with 33% water and 0.5-1% salt added and processed and kneaded to form dough balls of about 5 g ○ Machine operating conditions: Eccentricity ... Both δ ₁ and δ ₂ are 2.5 mm: Eccentric position: Second quadrant: Inclination angle θ: 0.3 ° (0.25 to 0.5 °): Lower disc acceleration time: 0 to 420 rpm To 1
0 seconds: Rolling time ... 4 seconds: Pressing pressure ... 10 kg ○ The molding material has a thickness of 0.8 mm at the central part and a thickness of 0.4 mm at the outer peripheral part, and the thickness changes smoothly to a diameter of 70-80.
A nearly perfect circle expanded to mm was obtained.

Experimental Example No. 2 ○ Raw material conditions: soft flour mixed with 35% water and 0.5-1% salt to knead to make dough balls of about 5 g ○ Machine operating conditions: eccentricity amount δ ₁ , Δ ₂ are both 2.5 mm: Eccentric position: Second quadrant: Inclination angle θ: 0.3 ° (0.25 to 0.5 °): Lower disk acceleration time: 1 to reach 0 to 420 rpm
0 seconds: Rolling time ... 3 seconds ○ As the molding material, the same material as in Example 1 was obtained. Depending on the machine operating conditions and the eccentric position, various phenomena such as non-rolling of the forming material, poor roundness, and adhesion to the upper disc can be seen, so it is necessary to select the conditions. Also, if the upper disc is rotated separately and the conditions for the lower disc are selected, a molded dough is obtained in the same manner. Further, it is also possible to directly feed the dough balls onto the disc below without using a conveyor to convey the dough balls.

[0022]

The present invention has the following effects by the method and apparatus as described above. Since each dough ball is rolled flat, there is no residual skin and it is economical. Also, since the rolling direction is not constant because it is rolled while being kneaded, and the strength is the same in all directions, there is no synergistic effect with the thick central part, so that the central part does not break when tools and pork paste are put in. There are no defective products. Furthermore, since the outer peripheral portion is thin, even if two sheets are stacked, the thickness is not particularly thick and the same thickness as that of the central portion provides a good texture. Furthermore, it has become possible to manufacture leather dough using raw materials such as weak wheat flour that could not be used conventionally. Furthermore, it is possible to continuously and easily make the same texture as the handmade leather dough, which is productive and can reduce the cost.
