Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the use of food materials, such as when making spherical tempura (commonly known as kyuten) by forming dough-like food materials mainly made of fish meat into spherical bodies and frying the spherical bodies. This invention relates to a spherical food forming device that shapes food into a spherical shape.

Generally, in this type of molding device, the food material supplied under pressure is extruded through a roughly trumpet-shaped molding hole, and an arc-shaped cutter is intermittently reversed within the molding hole, thereby shaping the extruded food material into a spherical shape. However, in the case of conventional equipment, an extremely complicated mechanism is used to reversely drive the arc-shaped cutter, resulting in frequent failures, and when there are multiple forming holes, each cutter must be individually Since it is necessary to provide a reversing drive means, the device itself becomes complicated and large-scale.

The present invention has been made in view of the above, and is a reversing drive means that has a simple structure, can operate reliably, and can easily drive each cutter in synchronization even in a device having a complicated formed hole. The purpose is to provide a molding device equipped with the following.

An embodiment of the apparatus of the present invention will be described below with reference to the drawings.

An example in which the present invention is applied to a spherical molding device will be explained below based on the drawings. In FIG. The kneaded tempura material, which is mainly composed of fish meat, is fed into the hopper 1 and is pushed downward by a screw 3 and sucked into a metering pump 4 at the bottom of the hopper 1. This metering pump 4 includes a horizontal cylindrical cylinder 5 that is integrally connected to the lower part of the hopper 1 so as to protrude toward the front side of the machine body 2, and a horizontal cylindrical cylinder 5 that is located in the cylinder 5 at a position offset from the center of the cylinder 5. A cylindrical rotor 6 is mounted on an axis so as to rotate as a rotor. It consists of a plurality of vanes 8 that are in constant contact with the side wall of the cylinder 5, and the material from the hopper 1 is supplied in a fixed amount between each vane 8 through the suction port 9, and is fed to the rotation of the rotor 6. While being compressed due to the accompanying change (reduction) in the volume between the vanes 8, 8, a fixed amount is continuously discharged from the discharge port 10. The rotors 6 of the push-in screw 3 and the metering pump 4 are rotationally driven by a common prime mover via a speed reduction mechanism and a transmission mechanism, respectively. 11 is a molding body connected to the oblong rectangular discharge port 10 of the metering pump 4;
1 has the above-mentioned discharge port 1, as is clear from FIG.
An inlet 12 adjacent to 0 is formed as an opening, and a plurality of distribution chambers 14 separated by partition walls 13 are arranged in a row at the inner depth of the inlet 12, and the bottom of each distribution chamber 14 has a diameter expanding downward. Approximately rasp-shaped molded hole 1 to open
5 is embedded and fixed, and the upper end nozzle portion 15a of this flap-shaped molded hole 15 opens at the center of the bottom of each distribution chamber 14. Further, a cylindrical cutter 17 is pivotally supported at the lower end discharge portion 15b of each flap-shaped molding hole 15 so as to rotate and traverse along the inner peripheral surface of the flap-shaped molding hole 15. That is,
As shown in FIGS. 1 and 3, the arcuate cutters 17 are fixed to one end of each rotating shaft 19 supported at regular intervals on a fixed frame 18 fixed to the lower surface of the mold body 11. A pinion 20 is attached to the other end of each rotating shaft 19, and a movable frame 22 formed by a rack 21 that meshes with each pinion 20 is slidably fitted into a guide groove 23 provided on the lower surface of the mold body 11. By reciprocating the movable frame 22 by a predetermined stroke, the arc-shaped cutter 17 is
... can be synchronized with each other and reversed forward and backward.

Reference numeral 24 denotes a rotary shaft as a driving shaft for reversing the arc-shaped cutters 17. The rotary shaft 24 is configured to rotate at a constant speed at a required speed by a motor (not shown) and a reducer. A cam-type intermittent reciprocating mechanism 25 is interlocked with the shaft for converting constant speed rotational motion into reciprocating linear motion and creating rest or stop periods at both ends of the reciprocating motion. This cam type intermittent reciprocating mechanism 25
As illustrated in FIG. 4, the holding plates 26, 27 have a pair of left and right circular holding plates 26, 27 that are fitted and fixed at regular intervals on the rotating shaft 24, and a cam 28 is formed inside. 27, and a reciprocating member 30 that is capable of vertically reciprocally sliding with respect to the rotating shaft 24 through the central guide elongated hole 29; It consists of a slider 31 that slides into contact with the cam 28 of the actuating member 30, and when assembling it, first the rotating shaft 2
4. Attach one retaining plate 26 to the tip of the central cylindrical part 26.
Then, the central guide elongated hole 29 of the reciprocating member 30 is fitted into the cylindrical portion 26a, and the other holding plate 27 is attached to the operating member 30, and the slider 31 is inserted into the cam 28. Further, the center hole 27a of the holding plate 27 is fitted to the tip of the rotating shaft 24, and then the latch protrusion 32a of the stopper plate 32 is inserted into the groove 27c of the outer cylinder part 27b of the holding plate 27 and the rotating shaft 24. Fit the screw 33 into the split groove 24a at the tip, and then insert the screw 33 through the center hole 32b of the stopper 32 into the rotating shaft 24.
It may be screwed into the screw hole 24b at the tip and tightened.
The cam 28 provided on the reciprocating member 30 is
A certain radius from the center of the rotating shaft 24 (i.e., the slider 31
A large circular arc portion 28 drawn with a length substantially corresponding to the turning radius of the slider 31 plus the radius of the slider 31.
A and 28B, and the large arc portion 28A, which is drawn with approximately the same radius as the radius of the skeleton 31,
It consists of small arcuate parts 28a and 28b that connect both ends of the cam 28B, and when the slider 31 is moved along the surface of the cam 28, the reciprocating piece 30 slides in accordance with the rotation of the rotating shaft 24. Child 31 is large arc part 2
8A, 28B, rest while passing through small arc part 28
When passing through a and 28b, it is forced to move upward or downward. Further, this reciprocating member 30 is connected to the bell crank 3 by a connecting fitting 34 attached to its lower end.
One arm 36 of 5 has a long hole 36 in the arm 36.
a and a pin 37. The bell crank 35 itself is the mold main body 11.
The other arm 38 of the crank 35 is pivotally connected to one end of the movable frame 22 on which the rack 21 is provided via its elongated hole 38a and pin 39.

The operation of the cam type intermittent reciprocating mechanism 25 having the above configuration will be explained with reference to FIGS. 5 and 6. The slider 31 rotates around the rotating shaft 24 at a constant speed due to the constant rotation of the rotating shaft 24. As shown in FIG. 5, the slider 31 rotates, that is, revolves.
If sliding starts counterclockwise from A, the reciprocating member 30 is at rest while sliding on this large arc portion 28 (indicated by A in FIG. 6), and the rotating shaft 24 is rotating. When the slider 31 enters the small arc portion 28a after rotating approximately 120 degrees from the start, the actuating member 30 begins to rise through the central guide elongated hole 29, and while the rotating shaft 24 rotates approximately 60 degrees. is pulled up to a predetermined stroke S (shown in FIG. 6B). The center of this slider 31 is the next large arc portion 28B
When it engages with the starting end of the slider 31, the upward movement is stopped and the slider 31 again enters a rest period over a rotation range of approximately 120° (indicated by C in FIG. 6), and the slider 31 moves to the next small arc portion 28b. At this point, the actuating member 30 is pushed downward and returns to its original position (as shown by D in FIG. 6). Note that the trajectories of the slider 31 and the actuating member 30 described above are sequentially shown by imaginary lines in FIG. In this way, during one rotation of the rotating shaft 24, the actuating member 30 reciprocates one predetermined stroke and takes a rest before and after that stroke.Moreover, in this case, the upward stroke and downward stroke are short, and conversely, twice. The rest period for each is relatively long. Therefore, during the upward and downward strokes of the actuating member 30, the movable frame 22 is slid in one direction or the other via the bell crank 35, whereby each cylindrical cutter 17 is moved in the correct direction via the rack 21 and pinion 20. The cutting operation by the cutter 17 is rapidly performed and a desired spherical body is formed by being reversed in a short time in the direction or in the opposite direction.

In the spherical forming operation of the dough tempura material, the material introduced into the mold body 11 from the discharge port 10 of the metering pump 4 is transferred to each distribution chamber 1 from the inlet 12.
4, and is injected into the lapper-shaped molding hole 15 from the nozzle portion 15a. When the material is injected into and passes through the forming hole 15, the flow rate of the material flowing down the periphery of the forming hole 15 is slower than the flow rate flowing down the center due to the frictional resistance of contact with the inner peripheral surface. In addition, since the forming hole 15 has a flat shape, it necessarily has a spherical shape and is discharged from the lower end discharge portion 15b. Therefore, this discharge part 1
At the time when the discharge end of the material discharged from 5b has a hemispherical shape, the arc-shaped cutters 17 rapidly reverse at the same time by the action of the cam type intermittent reciprocating mechanism 25, the bell crank 35, and the rack and pinion mechanism. A spherical body G is formed by cutting the material in the lapper-shaped forming hole 15 along the spherical surface. The thus-formed spherical body G is cut by the reversing action of the arc-shaped cutter 17, cutting off the edge of the following material, and falls onto the belt 41 of the spherical body conveyor 40 installed below. It is transported to an oil tank (not shown) for deep-frying. After forming the above-mentioned group of spherical bodies G..., each arcuate cutter 17 is reversed in the opposite direction after a certain rest period as described above, thereby forming the next group of spherical bodies G...
are formed, and these operations are repeated one after another to continuously produce a large amount of spherical food.

Furthermore, as a feature of the present invention, FIGS.
As shown in FIG. 3, an adjustment rod 42 is provided for adjusting the opening area of the upper end nozzle portion 15a of each of the ratchet-shaped molding holes 15. The nozzle portion 15a is supported so as to be slidable through the distribution chamber 14 and inserted into the nozzle portion 15a from the distribution chamber 14, and can be fixed at a desired position by a screw rod 43 screwed onto the upper wall portion. By providing this adjustment rod 42, it is possible to adjust the amount of food material extruded from each distribution chamber 14 into the bulge-shaped molding hole 15, and adjust the production amount of the spherical food to be molded as appropriate. .

As explained above, the spherical food forming apparatus of the present invention has a pinion attached to the support shaft of an arc-shaped cutter that is rotatably supported at the lower end discharge portion of the wrapper-shaped forming hole so as to rotate across the inner peripheral surface of the forming hole. This pinion is engaged with a rack that can reciprocate along its longitudinal direction, and a cam-type intermittent reciprocating mechanism is interlocked with a rotating shaft that rotates at a constant speed, and the reciprocating member of this intermittent reciprocating mechanism is held in a fixed position. The bell crank is pivoted to one arm of the rack, and the other arm is pivoted to one end of the rack, and the cam-type intermittent reciprocating mechanism allows the rotation of the rotating shaft, which rotates continuously at a constant speed, to be made intermittently. Since the circular cutter is converted into reciprocating motion and driven in forward and reverse directions via a bell crank and rack-pinion mechanism, the structure is extremely simple and compact, instead of being complicated and large as in the past. As a result, there are fewer failures and the equipment can be installed in a relatively small space.Also, by adopting a rack and pinion mechanism, multiple cutters installed in parallel can be driven in synchronization with each other, ensuring reliable operation of the cutters. At the same time, there is an advantage that the device itself can be further downsized and simplified.

Particularly, according to the present invention, an adjustment rod for adjusting the opening degree of the nozzle part is provided at each upper end nozzle part of the plurality of substantially trumpet-shaped forming holes connected in parallel to the discharge port of the food material supply pump. It is characterized by: By providing this adjustment rod, the amount of extrusion of the food material can be adjusted to adjust the production amount of the spherical food to be molded, and it can also be adjusted according to the consistency of the food material. In particular, by providing a plurality of molding holes in parallel in the supply pump, the discharge pressure of the supply pump applied to each molding hole changes slightly, and the amount of food material fed into each molding hole differs. By adjusting each adjustment rod, each molding hole can be evenly filled with the food material, thereby making it possible to efficiently produce more uniform spherical food than each molding hole. .
