The unrolling supply roller group 4 includes three horizontal unwinding supply rollers 41, 42, and 43 that are arranged in parallel. The three unwinding supply rollers 41, 42, 43 are arranged and rotated in a state substantially orthogonal to the feeding direction of the food feeding mechanisms 3, 3. The three unwinding supply rollers 41, 42, and 43 have an intermediate unwinding supply roller 42 on the driving side, and unwinding supply rollers 41 and 43 on both sides on the driven side. Reference numerals 41 and 43 rotate when the rotational force is transmitted from the unwinding supply roller 42 at the intermediate portion, while the rotation is stopped by being disconnected from the unwinding supply roller 42. In order to transmit and block this rotational force, transmission control means 10, 10 are provided between these unrolling supply rollers 41, 42, 43.
[0026]
The driving mechanism of the unrolling supply rollers 41, 42, 43 will be described with reference to FIGS. 1 and 4. The rotating shaft 11 is inserted into the unrolling supply rollers 41, 42, 43 arranged side by side. Is connected to one unwinding motor 13 as driving means through a gear train 12.
[0027]
An annular field (core) 15 made of a magnetic material is provided inside the middle supply roller 42, and a coil 16 is provided inside the field 15. The field 15 is engaged with the rotating shaft 11, whereby the middle-side unwinding supply roller 42 is driven to rotate as the rotating shaft 11 rotates.
[0028]
Armature hubs 17 and 17 are provided in the inside of the unwinding supply rollers 41 and 43 on both sides, respectively. Ball bearings 18 are provided between the respective armature hubs 17 and 17 and the rotary shaft 11, so that the release supply rollers 41 and 43 on both sides are in a state of being free of rotation with the rotary shaft 11. Yes.
[0029]
The transmission control means 10 and 10 are constituted by an electromagnetic clutch provided with a field 15 on the side of the tearing supply roller 42 and armatures 19 and 19 provided on the side of the tearing supply rollers 41 and 43. The field 15 including the coil 16 has splines 15a formed at both ends on the radially outer side. The armatures 19 and 19 are provided on the side facing the field 15 in the respective armature hubs 17 and 17, and splines 19a and 19a with which the splines 15a formed on the field 15 mesh are formed at corresponding positions.
[0030]
Splines 19b and 19b are formed on the opposite side of the splines 19a and 19a in the armatures 19 and 19, and the armature hubs 17 and 17 of the unwinding supply rollers 41 and 43 on both sides are connected to the splines 19b and 19b. The meshing splines 17b, 17b are formed.

Further, the respective armatures 19 and 19 are connected to the armature hubs 17 and 17 in a state of being prevented from coming off by connecting shafts 20 and 20 arranged in the axial direction between the armature hubs 17 and 17. Energizing members 21, 21 made of coil springs are attached to the connecting shafts 20, 20, thereby urging the armatures 19, 19 to move in the direction of the armature hubs 17, 17.
[0032]
In such a structure, when the coil 16 is energized, a magnetic flux is generated between the field 15 and the armatures 19 and 19, the armatures 19 and 19 are attracted to the field 15, and the corresponding splines 15 a and 19 a mesh. . As a result, the rotational force is transmitted from the intermediate part supply roller 42 to the both side release supply rollers 41, 43, so that the three release supply rollers 41, 42, 43 rotate simultaneously. Thus, a large amount of cooked rice B can be supplied by simultaneously rotating the three unwinding supply rollers 41, 42, and 43.
[0033]
On the other hand, when the energization to the coil 16 is interrupted, the armatures 19 and 19 are moved in the direction of the armature hubs 17 and 17 by the urging force of the urging member 21. Thereby, the connection between the armatures 19 and 19 and the field 15 is cut off. In this state, only the intermediate unwinding supply roller 42 rotates, and the unwinding supply rollers 41 and 43 on both sides do not rotate. In this way, when only the middle part unwinding supply roller 42 rotates, the cooked rice B can be supplied mainly from the center side as shown in FIG.

That is, since the nail | claw member 23 strikes not only the warm cooked rice just after cooking but the hard cooked rice vacuum-cooled, it can be dropped below in the state disassembled apart.
[0036]
Below the supply slope 25, a storage part 27 having a storage space 26 for temporarily storing the rice B is provided separately from the supply box 5. In the storage unit 27, the upper surface opening 27 a is independently arranged in a communication state with the lower surface of the supply box 5. In addition, a tapered portion 27b that is inclined from the outside to the inside so that the cooked rice B is concentrated in the center is formed inside the storage portion 27, and a narrow opening portion 27c communicates with the lower end of the tapered portion 27b. .
[0037]
As shown in FIGS. 3 and 6, one end of an arm 28 is attached to the outer surface of the storage portion 27, and the other end of the arm 28 is connected to a support base 30 via a support column 29. Accordingly, the storage unit 27 and the like are supported by the support base 30, but the support base 30 itself is supported by an electronic weighing scale (load cell) 31 a as the weighing mechanism 31. The electronic weighing scale 31a 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 27, the arm 28, the support column 29, the support base 30, and the like. It has become.
[0038]
The electronic weighing scale 31 a is connected to the above-described unwinding motor 13 via the control mechanism 33. Therefore, the rotation of the unlocking motor 13 is controlled by the control mechanism 33 that receives the signal from the electronic weighing scale 31a.

As shown in FIG. 5, the control mechanism 33 includes a weighing controller 34 and a rotation speed controller 35. The weighing controller 34 receives a signal from the electronic weighing scale 31 a and outputs the control signal to the rotation speed controller 35. The rotational speed controller 35 is connected to the unlocking motor 13 and controls the rotational speed of the unlocking motor 13 based on a control signal from the weighing controller 34. Thereby, since the rotational speed of the unwinding supply rollers 41, 42, and 43 is controlled, the supply amount of the cooked rice B can be adjusted.
[0040]
In the lower opening 27c of the reservoir 27, a pair of two shutters 36 that are driven to open and close in the horizontal direction are arranged. Each shutter 36 is connected to a drive device (not shown), and is intermittently opened and closed at a predetermined timing, whereby the cooked rice B in the storage space 26 of the storage unit 27 is supplied to the lower forming device 37.
[0041]
The forming device 37 is formed by a rotary table 38 in which a plurality of forming holes 38a are formed at appropriate intervals on the outer peripheral side of the upper surface, and forms the cooked rice B that has fallen into the forming holes 38a into a predetermined shape. In addition to the rotary table 38, the molding device 37 may be a conveyor device having molding holes formed on the upper surface at predetermined intervals.
[0042]
In such an embodiment, when the food feeding mechanisms 3 and 3 are rotationally driven, the cooked rice B is unwound while being collected on the center side and supplied to the supply roller group 4 side. In the unwinding supply roller 4, when the unwinding supply rollers 41, 43 on both sides are connected to the unwinding supply roller 42 in the intermediate portion by the transmission control means 10, the three rollers rotate simultaneously. As shown in Fig. 4, a large amount of cooked rice B can be unloaded and put into the storage unit 27.
[0043]
The weight of the cooked rice B that has fallen into the storage unit 27 is measured by the electronic weighing scale 31a. For example, when the weight reaches about 70% of the target weight, the transmission control means 10 disengages the supply rollers 41 on both sides. , 43 are disengaged from the unrolling supply roller 42 at the intermediate portion. Thereby, since one unwinding supply roller 42 is rotationally driven, the remaining cooked rice B can be dropped in the center as shown in FIG. Thereby, the supply amount of cooked rice B can be adjusted at the end stage of feed, and the quantitative supply of cooked rice B can be performed accurately.
[0044]
Therefore, in such an embodiment, since a fixed amount of cooked rice can be supplied with a single structure without providing a main weighing unit and an auxiliary weighing unit, it is possible to reduce the size and cost.
[0045]
In this embodiment, in addition to the above-described control of connection and disconnection to the disengagement supply roller, it is also possible to control the rotation speed of the disengagement motor 13 by the weighing controller 34 and the rotation speed controller 35. As a result, it is possible to provide a quantitative supply with higher accuracy.
[0046]
The present invention is not limited to the above embodiment, and various modifications can be made. For example, as long as there are at least three supply rollers, four or more supply rollers may be provided in parallel. In this case, the transmission control means 10 is provided between the rollers to connect and disconnect the rollers. Can do. Further, the connection and disconnection of the disengagement supply roller may be formed by means other than the electromagnetic clutch, for example, a pin that is controlled to appear and retract and its receiving hole.
[0047]
【The invention's effect】
