Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to a food product such as a pastry-like food mainly made of fish meat, a food product in which the material is formed into a spherical body and then fried in oil to make spherical tempura. This invention relates to a spherical food forming device that shapes materials into spherical shapes.

Generally, in this type of forming apparatus, the food material supplied under pressure is extruded through a substantially trumpet-shaped forming hole, and the arc-shaped cutter is intermittently reversed within the forming hole, thereby forming the extruded food material into a spherical shape. However, in the case of conventional equipment, an extremely complicated mechanism is used to drive the circular cutter in reverse, so failures occur frequently.
Further, when there are a plurality of forming holes, it is necessary to provide a reversing drive means for each cutter individually, which makes the device itself complicated and time-consuming.

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 an apparatus having a plurality of forming holes. 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 implemented in a ball injection molding device will be explained below based on the drawings. In FIG. The linear tempura material, which is mainly composed of fish meat, is put 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.The rotor 6 is arranged radially with respect to the rotor 6, and each tip is in constant elastic contact with the inner circumferential surface of the cylinder 5 by a spring T. 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 then transferred to the rotor 6.
While being compressed due to a change (reduction) in the volume between the vanes 8 and 8 as the volume rotates, 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 rotatably driven by a common prime mover via a reduction mechanism and a transmission mechanism, respectively.

Reference numeral 11 denotes a mold body connected to the oblong rectangular discharge port 10 of the metering pump 4, and as is clear from FIG. 2, the mold body 11 has an inlet 12 adjacent to the discharge port 10.
An opening is formed, and a partition wall 13 is formed deep inside this population 12.
A plurality of distribution chambers 14 divided by ... are arranged in succession, and a cap 16 having a substantially trumpet-shaped molded hole 15 whose diameter expands downward is buried and fixed in the bottom of each distribution chamber 14. The upper end nozzle portion 15a of the trumpet-shaped molded hole 15 opens at the center of the bottom of each distribution chamber 14.

Further, an arc-shaped cutter 17 is pivotally supported at the lower end discharge portion 15b of each trumpet-shaped forming hole 15 so as to rotate and traverse along the inner peripheral surface of the trumpet-shaped forming hole 15.

That is, as shown in FIGS. 1 and 3, the arc-shaped cutters 17... have rotary shafts 19 supported at regular intervals on a fixed frame 18 fixed to the lower surface of the mold body 11. A movable frame 22 is fixed to one end of each shaft, a pinion 20 is attached to the other end of each rotating shaft 19, and a movable frame 22 forming a rack 21 that meshes with each pinion 20 is inserted into a guide groove 23 provided on the lower surface of the mold body 11. They are fitted in a slidable manner, and by reciprocating the movable frame 22 by a predetermined stroke, the arcuate cutters 17 can be rotated forward and backward in synchronization with each other.

Reference numeral 24 denotes a rotary shaft as a driving shaft for reversing the arcuate cutters 11, which is rotated at a constant speed by a motor (not shown) and a reducer, and this rotary shaft 24 includes: a cam-type intermittent reciprocating mechanism 25 for converting constant speed rotational motion of the rotary shaft into reciprocating linear motion and creating a rest or stop period at both ends of the reciprocating motion;
are linked together.

This cam-type intermittent reciprocating mechanism 25, as illustrated in FIG. A reciprocating member 30 is formed and inserted between the holding plates 26 and 27 and is capable of vertically reciprocatingly sliding with respect to the rotating shaft 24 through the central guide elongated hole 29, and one circular holding plate 2.
7 and a slider 31 that is pivotally supported on the inner circumference of the rotary shaft 24 and slides into contact with the cam 28 of the operating member 30. When assembling the slider 31, first attach one of the retaining plates 2 to the tip of the rotating shaft 24.
6 through its central cylindrical portion 26a, then the central guide elongated hole 29 of the reciprocating actuating member 30 is fitted into this cylindrical portion 26a, and then the other holding plate 27 is attached to this actuating member 30. At the same time, the slider 31 is engaged with the cam 28, and the center hole 27a of the holding plate 27 is fitted to the tip of the rotating shaft 24,
After that, the latching protrusion 32a of the stopper 32 is connected to the groove 2γC of the outer cylinder portion 27b of the holding plate 27 and the groove 2 of the tip of the rotating shaft 24.
4a, and finally screw the screw 33 through the center hole 32b of the stopper 32 into the threaded hole 24b at the tip of the rotating shaft 24 and tighten.

The cam 28 provided on the reciprocating member 30 has a fixed radius from the center of the rotating shaft 24 (that is, the length substantially corresponds to the sum of the turning radius of the slider 31 and the radius of this slider 31).
The large arcuate portions 28A and 28B are drawn with the same radius as the slider 31, and the large arcuate portion 28A is drawn with a radius that is approximately the same as the radius of the slider 31.

Small arc parts 28a and 28 that connect both ends of 28B
b, and slider 31 is attached along the surface of this cam 28.
When the reciprocating piece 30 slides, the reciprocating piece 30 rests while the slider 31 passes through the large arc portions 28A and 28B in accordance with the rotation of the rotary shaft 24, and moves to the small arc portion 28a.

When passing through 28b, it is forced to move upward or downward.

Further, this reciprocating member 30 is pivotally connected to one arm 36 of a bell crank 35 via a long hole 36a and a pin 37 of the arm 36 by a connecting fitting 34 attached to its lower end.

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 the elongated hole 38a and the pin 39.

Cam type intermittent reciprocating mechanism 25 having the above configuration
The operation of slider 31 will be explained with reference to FIGS. 5 and 6.
rotates or revolves around the rotating shaft 24 at a constant speed due to the constant rotation of the rotating shaft 24.

Therefore, as shown in FIG.
Assuming that the cam 28 starts sliding counterclockwise from the large circular arc portion 28A due to the rotation of ), and after the rotary shaft 24 has rotated approximately 120° from the start of rotation, the slider 31 enters the small arc portion 28a, the actuating member 30 starts to rise through the central guide elongated hole 29, and rotates. While the shaft 24 rotates approximately 60 degrees, it is pulled up to a predetermined stroke S (as shown by the opening in FIG. 6).

At the point when the center of this slider 31 engages with the starting end of the next large arc portion 28B, the upward movement is stopped and a rest period covering a rotation range of approximately 120° is entered again (indicated by C in FIG. 6). When the slider 31 moves to the next small arc portion 28b, the actuating member 30 is pushed downward and returns to its original position (as shown by 2 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 the stroke.Moreover, in this case, the upward stroke and downward stroke are short, and conversely, the actuating member 30 reciprocates one predetermined stroke. Each period of rest 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, thereby causing the rack 21 and pinion 2 to slide in one direction or the other.
0..., each arcuate cutter 17 is reversed in a short time in the forward or reverse direction, and thereby the cutting operation by the cutter 11 is rapidly performed to form a desirable spherical body. .

In the spherical forming operation of the linear tempura material, the material introduced into the mold body 11 from the discharge port 10 of the metering pump 4 is distributed into each distribution chamber 13 through its population 12, and is sent to the trumpet from the nozzle portion 15a. It is injected into the shaped molding hole 15.

The material injected into and passing through the molding hole 15 is
Because the flow velocity of the material flowing down the circumferential part of the forming hole 15 is slower than the flow velocity flowing down the center part due to the frictional resistance of contact with the inner circumferential surface, and because the forming hole 15 has a trumpet shape, The lower end discharge portion 15 necessarily has a spherical shape.
It is discharged from b.

Then, when the discharge end of the material discharged from the discharge portion 15b has a hemispherical shape, the cam type intermittent reciprocating mechanism 2
5, the bell crank 35, and the rack and pinion mechanism, the arcuate cutters 17 rapidly reverse at once, thereby cutting the material in the trumpet-shaped forming hole 15 along the spherical surface to form the spherical body G.

The spherical body G thus formed is cut by the arc-shaped cutter 17.
Due to the reversal action of the material, it is cut off from the following material and falls onto the belt 41 of the spherical object conveyor 40 installed below, and is cut into an oil tank for deep-frying tempura (not shown).
transported to.

After forming the above group of spherical bodies G, each arcuate cutter 17 is reversed after a certain rest period as described above, thereby forming the next group of spherical bodies G.
... is formed, and these operations are repeated one after another to continuously produce a large amount of spherical food.

In addition, 42 in FIGS. 1 to 3 indicates each of the above-mentioned trumpet-shaped molded holes 15.
An adjustment rod for adjusting the opening area of the upper end nozzle part 15a vertically slides through the upper end of each distribution chamber 13 of the mold main body 11 to remove the nozzle part 5 from the distribution chamber 13.
It is supported so that it can be inserted into the interior of a, and can be fixed at a desired position by a screw rod 43 screwed into the upper wall.

By providing this adjustment rod 42, the amount of food material extruded from each distribution chamber 13 into the trumpet-shaped molding hole 15 can be adjusted, and the production amount of the spherical food product to be molded can be adjusted as appropriate. .

As explained above, the spherical food forming apparatus of the present invention has a pinion attached to the spindle of an arc-shaped cutter that is rotatably supported at the lower end discharge portion of the trumpet-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, while a cam-type intermittent reciprocating mechanism is interlocked and connected to 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 pivot is on one arm of the bell crank which is pivoted on the! At the same time, the other arm is pivotally connected to one end of the rack, and a cam-type intermittent reciprocating mechanism converts the rotation of the rotary shaft that rotates continuously at a constant speed into intermittent reciprocating motion, and furthermore, a bell crank and a rack/pinion are connected. Since the arc-shaped cutter is driven in forward and reverse directions through a mechanism, the structure is not complicated and large as in the past, but is extremely simple and compact, with less failure and the equipment can be installed in a relatively small space. In addition, by adopting a rack and pinion mechanism, each cutter can be driven in synchronization with each other even in the case of multiple molding, so the operation of the cutters can be ensured, and the device itself can be further downsized and simplified. There are advantages.
