BACKGROUND OF THE INVENTION
The present invention relates to a food unraveling and feeding apparatus for weighing and feeding granular food such as cooked rice.
[0002]
[Prior art]
In this type of conventional supply device, food, for example, cooked cooked rice, is put into a hopper, and conveyed by a conveyor conveyer arranged below the hopper, by a breaking mechanism (unwinding blade) arranged above the hopper. After the cracking, the cracked cooked rice is transferred downward while being gradually compressed by the feed roller and the compression roller arranged in the vertical direction at the end of the conveyor. Then, a shutter provided on the downstream side in the transfer direction is moved in the left-right direction and cut into a predetermined amount of blocks to form a substantially square block shape. In this case, the rice cracking mechanism has a structure using a stirring bar having a plurality of bars protruding from the outer surface of the rotating shaft or a screw blade having a spiral plate around the rotating shaft. Yes. In addition, the block-shaped formed rice is then formed into a shape suitable for various uses.

[Problems to be solved by the invention]
However, the cooked rice conveyor and unloading mechanism used in the conventional cooked rice supply apparatus have the following problems.
When food is fed by the conveyor, it moves on the conveyor at the position where it is put in from the hopper, so the amount of food varies greatly between the left and right sides of the conveyor. Is difficult. In particular, it is difficult to unravel the cooked rice that has been hardened by vacuum cooling, and block-like lumps tend to occur.
[0004]
And when unraveling is insufficient in this way, it is easy to produce unevenness in the density of the cooked rice supplied between the rollers of the next process. For this reason, it has been difficult to measure and divide into a constant weight and provide the cooked rice to a molding mechanism or the like.
That is, conventionally, there are many problems in weighing accuracy, and there is a problem that it is impossible to obtain cooked rice with a constant weight.
[0005]
The present invention has been made in consideration of such a conventional problem, and a large amount of food is quickly and forcibly fed so as to be concentrated near the center of the unrolling supply roller with a claw member protruding on the outer surface. This means that the whole food can be unwound evenly by the unwinding and feeding roller, so that there is little variation in weighing accuracy, and constant weight weighing food can be obtained easily and reliably. The purpose is to provide.

That is, the rotary shafts 6a and 6a are interlocked and connected to the output shaft 7a of the motor 7 through three gears 8a, 8b and 8c, so that the feed conveyors 6 and 6 are as shown by the arrows in FIG. They are designed to rotate inward from each other. When the feed conveyors 6 and 6 are rotationally driven in this way, the cooked rice B introduced into the hopper 2 is transferred to the downstream side while being gradually moved toward the center along the longitudinal direction of the feed conveyors 6 and 6. As a result, the cooked rice B is gathered to the center side of the unrolling supply roller 4, and the uncooked rice B unwound by the unwinding supply roller 4 is concentrated and supplied to a forming hole or the like of a forming apparatus to be described later.

The feed amount of the cooked rice B can be adjusted by changing the inclination of the upper guide plate 9 and the distance between the upper guide plate 9 and the unwinding supply roller 4.
[0013]
The unrolling supply roller 4 has a rotating shaft 4a inserted in the center thereof and rotates around the rotating shaft 4a. In this case, the rotating shaft 4a is arranged so as to be substantially orthogonal to the rotating shafts 6a and 6a of the feed conveyors 6 and 6 in the food feeding mechanisms 3 and 3, and thereby the supply roller 4 is disengaged. Is rotated in a state substantially perpendicular to the feed direction of cooked rice B.
The rotating shaft 4 a of the unrolling supply roller 4 is connected to a motor 11 as a driving device via a gear train 10.
[0014]
A plurality of claw members 12 are provided on the outer surface of the unrolling supply roller 4 in a spiral arrangement. When the unwinding supply roller 4 rotates, the nail members 12 on the outer surface act to come into contact with the cooked rice B.
[0015]
As shown in FIGS. 6 and 8, the claw members 12 are arranged so as to form a multiple row in an oblique direction with respect to the rotational direction M of the unwinding supply roller 4. In the figure, L1, L2, L3... Indicate adjacent columns in order to form a multiple column. In adjacent rows (for example, L 1 and L 2), the claw member 12 is unwound and overlaps in the rotation direction M of the supply roller 4. For example, when the rotation direction M of the supply roller 4 is the X axis and the width direction is the Y axis, the claw members 12-A in the row L1 and the claw members 12-B in the row L2 as shown in FIG. By arranging the claw member 12 so as to be at the same position on the Y axis orthogonal to the rotation direction M, the claw member 12 can be repeatedly contacted with the cooked rice B and unraveled.

[0017]
In the claw member 12, the triangular claw 12 a is formed so that the front side in the rotation direction M of the unwinding supply roller 4 is a vertical bottom surface orthogonal to the rotation direction M and is integrally protruded from the outer surface of the supply roller 4. . The rectangular claws 12b and the elliptical claws 12c are also integrally projected so that their length directions are perpendicular to the rotational direction M of the supply roller 4.
The length (height) of each claw member 12 is preferably formed in a short length of about 7 to 10 mm.
[0018]
On the other hand, as shown in FIG. 2, the supply box 5 is formed with a supply slope 13 that faces the unrolling supply roller 4. The claw member 12 provided on the outer surface of the supply roller 4 is released while moving between the roller 4 and the supply slope 13. That is, not only warm cooked rice immediately after cooking, but also hard cooked rice vacuum-cooled, a number of short claw members 12 are continuously beaten downward from above, so that they are broken apart and moved downward. Fall.
[0019]
A storage portion 15 having a storage space 14 for temporarily storing the cooked rice B is separately provided below the supply slope 13. That is, the upper surface opening 15a of the storage unit 15 is independently arranged in communication with the lower surface of the supply box 5, while the inside is from the outside to the inside so that the cooked rice B is concentrated in the center. It is formed in the taper 15b which inclines and descends, and the narrow opening 15c is formed in the lower surface by this.
[0020]
As shown in FIGS. 3 to 5, an arm 16 is attached to the side surface of the storage portion 15, and the other end of the arm 16 is connected to a support base 18 via a support column 17. In this way, the storage unit 15 and the like are supported by the support base 18, but the support base 18 itself is also supported by an electronic weighing scale (load cell) 19 a as the weighing mechanism 19. The electronic weighing scale 19a measures the weight of the cooked rice B by subtracting the weight other than the cooked rice B from the measured value after weighing the storage unit 15, the arm 16, the support column 17, the support base 18, and the like. is there.
[0021]
Further, the electronic weighing scale 19a is electrically connected to the motor 11 via the control device 20, and is controlled by the control device 20 that receives a signal from the electronic weighing scale 19a to control the rotation speed of the supply roller 4. It is like that.
[0022]
That is, the rotational speed of the unrolling supply roller 4 is initially rotated at a high speed, and, for example, 70% by weight B-1 of the cooked rice weight to be supplied as shown in FIG. Fill at once.
Next, after rotating at medium speed and filling with 20 wt% B-2 as shown in FIG. 4, the remaining amount (10 wt%) B-3 is filled with paraffin as shown in FIG.
In this way, by gradually decreasing the rotation speed of the supply roller 4, the electronic weighing scale 19a can be measured with high accuracy.
[0023]
In the lower opening 15c of the reservoir 15, a pair of two shutters 21 that are driven to open and close in the horizontal direction are arranged. Each shutter 21 is linked to a driving device (not shown) and is intermittently opened and closed at a predetermined timing, whereby the cooked rice B in the storage space 14 of the storage unit 15 is supplied to the lower molding device 22.

The food unrolling supply rollers 4A and 4A are abutted on the same axis, and the rotation shafts of the rollers 4A and 4A are linked to the two motors 11A and 11A arranged opposite to each other via the gear trains 10A and 10A. By being connected, each is independently driven to rotate.
[0025]
Along with this, the feed conveyors 6 and 6 are also connected to the two motors 7A and 7A that are oppositely arranged on both sides with the gear trains 8A and 8A separately attached to the respective rotating shafts 6A and 6A. Thus, each is driven to rotate independently.
As shown by the arrows in FIG. 10, the feed conveyors 6 and 6 rotate inward as in the first embodiment.
[0026]
Accordingly, also in this case, the cooked rice B put into the hopper 2 is gradually gathered to the center side of the food unrolling supply rollers 4A, 4A arranged on the downstream side along the longitudinal direction of the feed conveyors 6, 6. Further, two control devices 20A and 20A are provided between the motors 11A and 11A on both sides of the food unrolling supply rollers 4A and 4A and the weighing mechanism 19.
[0027]
The food unrolling supply rollers 4A and 4A first rotate both rollers 4A and 4A at high speed to fill 70% by weight B-4 of the cooked rice weight, then stop one roller 4A and rotate only the other roller 4A. Filling the weight% B-5, and finally gradually filling the remaining space B-6 into the storage space 14 of the storage unit 15 by gradually reducing the rotational speed of the roller 4A. As with the configuration, the measurement by the measurement mechanism 19 can be performed with high accuracy.
