2. Description of the Related Art In general, the sorting and sorting of perishables and the like having non-uniform shapes and sizes depend on the manual operation of an operator, while fixed products are quantitatively supplied to a weighing device and sorted. There are many parts, and this is a bottleneck in improving work efficiency. FIG. 7 shows an example of a weight sorting step of a frozen scallop as an example of an amorphous material. Normally, frozen scallops are obtained by freezing fresh scallops, sorted by weight, boxed and shipped. At this time, since the scallop is not constant in shape and size, even if it is frozen, the frozen scallop cannot be supplied to the automatic weighing device as it is. Therefore, each step as shown in FIG. 7 is provided to continuously supply the frozen scallops to the automatic weighing device. This weight sorting process is roughly composed of a feeding process 100, an accelerating process 110, a weighing process 120, and a sorting process 130, of which the feeding process 1
00 is equipped with a belt conveyor 102 in which partition plates 101 are formed at predetermined intervals. Since the conveyor 102 rotates at 5 to 6 m / min, workers are separated by the partition plates 101 of the conveyor 102. Frozen scallops A
Are placed one by one. Conveyor 11 of acceleration process 110
1 is set at a speed of about 10 m / min, so that the frozen scallops A transported from the supply step 100 and arranged substantially in a row are widened and sent to the conveyor 121 of the adjacent measuring step 120. Has become. This weighing process 1
At 20, the frozen scallops A are weighed one by one by the measuring device 122, and the frozen scallops A are measured based on the weight data measured here.
Is sorted in the sorting chute 131 arranged by weight in the next sorting / sorting step 130.

However, in the above-mentioned weight sorting process, the operator must place frozen scallops one by one on the conveyor in the supplying process, and the speed of the conveyor is reduced due to the manual operation. Also has limitations, and cannot supply frozen scallops that are high-speed and amorphous,
It is a critical path for efficient weight sorting work. Also, prior to the weighing process, the interval between the frozen scallops is increased in the acceleration process, so the position of the frozen scallops often shifts, and it is necessary to arrange another worker in the acceleration process to correct this shift There is a problem that labor saving cannot be achieved.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a fixed-quantity supply apparatus for an irregular-shaped article which can arrange irregular-shaped articles and supply the fixed-quantity article to a weighing device at a high speed. .

And a road.

[0006]

According to the present invention, the solid amorphous material fed from the supply hopper is transferred from the central axis of the apparatus along the inclined groove of the first distributing means formed radially from the apparatus central axis. The first shielding means disposed on the outer periphery of the distribution means is opened / closed by an opening / closing signal from the detection means, and the opening operation of the first shielding means causes the irregularly-shaped objects transferred from the first distribution means to pass through the first shielding means. The two distributing means are arranged and transferred in a line along an inclined groove formed radially from the central axis of the apparatus, and are simultaneously opened by the second shielding means disposed on the outer periphery of the second distributing means. Then, after confirming that one amorphous material has passed, the shielding operation is performed, and the amorphous material discharged from the second distributing means can be uniformly opened to the bottom by the simultaneous opening operation of the second shielding means. Housed in a distribution chute having a shutter mechanism,

The vibrator 31 is fixed on a stationary vibrator 31 which is spring-supported on its surface, and is vibrated. Further, the trough 32 has a substantially trapezoidal cross section formed by bending a flat steel material, and a swing shutter 40 as a second shielding means is attached to each of the trough discharge ends 32a similarly to the upper chute 4. I have. The swing shutter 40 includes a support plate 41 fixed to the shutter support frame 2.
, And swings with respect to the hinge 43 by the operation of the air cylinder 42, so that the trough end 32a can be opened and shielded at a predetermined timing. A urethane rubber gate 44 is attached to the tip of the swing shutter 40. Ten photoelectric sensors 45 are arranged below the outer periphery of the upper chute 4 and inside the lower chute 30 so as to check the presence or absence of frozen scallops in the trough 32 of each lower chute 30. .

Further, at the outer peripheral position of each lower chute 30, ten distribution chutes 50 are arranged. The distribution chute 50 has a cylindrical shape having a square cross section.
Is detachably fixed to the outer periphery of the device via a fixture 51. An input sensor 5 on the outer surface of the distribution chute 50 for confirming that the frozen scallop has been input into the inside.

The bottom of the distribution chute 50 is constituted by a plate-shaped shutter mechanism 53. The shutter mechanism 53 is slid by an actuator 54 fixed to the lower surface of the base 11, and can freely open and shield the bottom of the distribution chute 50. On the other hand, below the base 11, a rotating shaft 14 rotatable by a drive source 13 housed in the gantry 10 is housed supported by a bearing 15. A rotating plate 60 is fixed to the rotating shaft 14 below the base 11. The rotating plate 60 has substantially the same diameter as the base 11, and a plurality of partition plates 62, 62... This partition plate 62
Is approximately 2 with respect to the mounting plate 61 as shown in FIG.
Fifteen sheets are fixed at an interval of 4 °, and a pocket 64 partitioned into 15 chambers forms a continuous circumferential conveyance path 65 between the outer wall plate 63 and the outer wall plate 63. At this time, the outer circumference of the alignment table 16 and the circumferential conveying path 65 constituting the upper surface of the gantry 11 are equal, and a part of the alignment table 16 is cut out in a substantially triangular shape as shown in FIG. A discharge port 17 of the transport path 65 is formed, and a conveyor (not shown) is disposed below the discharge port 17.
