2. Description of the Related Art Generally, the weight sorting and sorting of perishable foods, etc., which are not uniform in shape and size, is dependent on the manual work of workers, while the fixed shaped products can be quantitatively supplied to a weighing device and sorted. There are many parts, which is a bottleneck in improving work efficiency. FIG. 7 shows an example of a weight sorting process of frozen scallops as an example of an irregular shaped product. Frozen scallops are usually frozen fresh scallops, sorted by weight and packed in boxes before shipment. At this time, since the scallops are not constant in shape and size, the frozen scallops cannot be directly supplied to the automatic weighing device even when frozen. Therefore, each step as shown in FIG. 7 is provided in order to continuously supply the frozen scallops to the automatic weighing device. The weight selection process is roughly composed of a supply process 100, an acceleration process 110, a weighing process 120, and a sorting / sorting process 130. Of these, the supply 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, the worker is partitioned by the partition plate 101 of the conveyor 102. Frozen scallop A on the
Place one by one. Conveyor 11 for acceleration process 110
1 is set to a speed of about 10 m / min, and the frozen scallops A that are transferred from the supply process 100 and arranged in almost one row are widened so that they are sent to the conveyor 121 of the adjacent weighing process 120. Is becoming This weighing process 1
At 20, the frozen scallop A is weighed one by one with the weighing device 122, and the frozen scallop A is weighed based on the weight data weighed here.
Are sorted by the sorting chute 131 arranged by weight in the next sorting and sorting step 130.

[0003]

However, in the above-mentioned weight selection process, the worker must put frozen scallops on the conveyor one by one in the supply process. There is also a limit, and it is not possible to supply frozen scallops that are amorphous at high speed,
It is a critical path for improving the efficiency of weight selection work. Also, prior to the weighing process, the frozen scallops are widened during the acceleration process, so the frozen scallops often shift in position, and it is necessary to place another worker in the acceleration process to correct this shift. However, there is a problem that labor saving cannot be achieved.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide an irregular shaped material constant quantity feeding device capable of aligning irregular shaped objects and quantitatively feeding them to a measuring device at high speed. ..

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus for quantitatively supplying irregular shaped material according to the present invention will be described below with reference to the accompanying drawings. In FIG. 1 and FIG. 2, reference numeral 1 is a front view showing the whole of the irregular-shaped object quantitative supply device, and the irregular-shaped object quantitative supply device 1 is at a central position of a shutter support frame 2 for suspending a shielding means such as a shutter. A supply hopper 3 is attached to. The supply hopper 3 has a substantially cylindrical shape and can receive a large amount of frozen scallops fed from a frozen scallop feeding device (not shown). Below the supply hopper 3, an upper chute 4 which is a first distributing means is arranged. This upper shoot 4
Is an inclined chute radially formed from the central axis of the apparatus, and as shown in FIG. 3, ten troughs 5 each having a trapezoidal cross section are developed so as to radially incline radially outward and incline. ing. Also, this upper chute 4 is a gantry 1.
The base 11 is placed on the surface of the base 0 and is spring-supported via a support column 12 so that it can be vibrated by a vibrator 6 attached to the lower surface. As shown in FIG. 3, the troughs 5 are formed at intervals of approximately 24 °, and the troughs 5 are formed only in the portions that form approximately 216 ° at the trough centerline position, forming a fan shape as a whole. ing. Further, the discharge end 5a of the trough 5 has a V-shaped cross section, and all the trough discharge ends 5a are provided with swinging shutters 20 as first shielding means. The swing shutter 20 is a cylindrical tube 21 fixed to the shutter support frame 2.
Is suspended from the hinge 23 by the operation of the air cylinder 22.
With respect to, the trough end 5a can be opened and shielded at a predetermined timing. The swing shutter 2
A gate 24 made of urethane rubber is attached to the tip of 0 so as not to damage the frozen scallops and the like.

Further, a second portion is provided on the outer peripheral position of the upper chute 4.
Lower chutes 30 as a distributing means of the above are arranged radially and at an inclination angle substantially equal to the inclination angle of the upper chutes 4. The lower chute 30 is arranged at an angle equal to the angle formed by the trough 5 of the upper chute 4, and the base 11
The vibrator 31 is fixed on a stationary vibrator 31 that is spring-supported on the surface and is vibrated. Further, the trough 32 is formed by bending a flat steel material and has a substantially trapezoidal cross section. Like the upper chute 4, all the trough discharge ends 32a are provided with swinging shutters 40 as second shielding means. There is. The swing shutter 40 includes a support plate 41 fixed to the shutter support frame 2.
The trough end 32a can be opened and shielded at a predetermined timing by swinging with respect to the hinge 43 by the operation of the air cylinder 42. A urethane rubber gate 44 is attached to the tip of the swing shutter 40. Ten photoelectric sensors 45 are provided below the outer periphery of the upper chute 4 and inside the lower chute 30 to check the presence or absence of frozen scallops in the trough 32 of each lower chute 30. ..

Further, ten distribution chutes 50 are arranged at the outer peripheral position of each lower chute 30. The distribution chute 50 has a tubular shape with a rectangular cross section, and
Is removably fixed to the outer periphery of the via a fixture 51. Also, on the outer surface of the distribution chute 50, a feeding sensor 5 for confirming that frozen scallops have been fed inside.
2 is installed. A photoelectric switch or the like is used as the closing sensor 52, and when the swing shutter 40 is opened and one frozen scallop falls inside the distribution chute 50, the closing sensor 52 detects this and the swing shutter 4 is opened.
It is designed to block 0. As a result, the frozen scallops are distributed to the distribution chute 5 by one opening / closing operation of the swing shutter 40.
One can be accommodated in 0.

The bottom of the distribution chute 50 is composed of a plate-shaped shutter mechanism 53. The shutter mechanism 53 can be slid by an actuator 54 fixed to the lower surface of the base 11 to freely open and shield the bottom of the distribution chute 50. On the other hand, below the base 11, a rotary shaft 14 rotatable by a drive source 13 housed in the gantry 10 is supported and accommodated in a bearing 15. A rotary plate 60 is fixed to the rotary shaft 14 below the base 11. The rotary plate 60 has a diameter substantially the same as that of the base 11, and a plurality of partition plates 62, 62 ... Are arranged on the outer peripheral edge of the rotary plate 60 via a mounting plate 61. 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 between the outer wall plate 63 and the outer wall plate 63, a pocket 64 divided into 15 chambers forms a continuous circumferential conveyance path 65. At this time, the outer diameter of the alignment table 16 forming the upper surface of the gantry 11 is equal to that of the circumferential conveying path 65, and a part of the alignment table 16 is notched into a substantially triangular shape as shown in FIG. The discharge port 17 of the transport path 65 is configured, and a conveyor (not shown) is arranged below the discharge port 17.

The lead wires 17 and 1 of the photoelectric switch and the like
8 and 19 are housed in a circumferential rack 18 provided on the outer periphery of the shutter support frame 2 and guided to a control unit (not shown). Further, the support column 19 for supporting the shutter support frame 2 has a built-in rod that can extend upward, and by extending this rod, the shutter support frame 2 can be raised, whereby the upper chute 4 and the lower chute can be raised. It is possible to remove the swing shutters 20 and 40 covering 30 and expose the upper chute 4 and the lower chute 30. As a result, the entire device can be easily cleaned after the work. This is a very important advantage in equipment handling fresh products. Further, since each part of each chute and vibrator is fixed by a fixture such as a hook, each part can be easily installed, assembled and disassembled on the base. In addition, each part is made by processing stainless steel material, but when the chute is vibrated by a vibrator, the frozen scallop can move the chute smoothly. A fluorinated ethylene resin coating is formed.

Next, the operation flow of the apparatus for supplying the frozen scallops one by one by the irregular shaped material quantitative supply apparatus according to the present invention will be described with reference to FIG. The same figure (a)
Shows a state in which the frozen scallop A is thrown into the upper chute 4 of the apparatus 1 by the frozen scallop feeding device (not shown). At this time, the swing shutter 20 is in the closed state,
The thrown-in frozen scallop A is radially directed along the ten troughs 5 of the upper chute 4. Next, as shown in FIG. 3B, when the upper chute 4 is vibrated by the vibrator 6 with the swing shutter 20 opened, the frozen scallop A in the trough 5 is transferred to the lower chute 30. The transfer timing of this frozen scallop A is determined by the photoelectric sensor 45 being the frozen scallop A in the trough 32 of the lower chute 30.
The rocking shutter 20 is opened when the number is smaller than a predetermined number. FIG. 6C shows a state in which the swing shutter 40 is simultaneously opened, and the vibration of the vibrator 31 causes the frozen scallops to drop onto each distribution chute 50. At this time, the input sensor 52 is 1 for frozen scallop A.
It is detected that the individual pieces have fallen, and the swing shutter 40 is shut off. Then, as shown in FIG.
The shutter mechanism 53 is opened all at once, and the frozen scallops are dropped and stored in the ten pockets 64 of the circumferential conveyance path 65. From this state, the rotary plate 60 rotates at a predetermined rotation speed in the arrow direction shown in FIG. At this time, since the partition plate 62 is slightly tilted rearward with respect to the rotation direction, the pocket 6
Each of the frozen scallops A housed in the table 4 moves to the inner surface of the outer wall plate by the centrifugal force and acceleration accompanying the rotation of the rotating plate. When the rotary plate rotates 2/3 in this state, the frozen scallops at the C position move to the D position.
The alignment table 16 corresponding to the bottom of the is cut out,
When the rotary plate 60 rotates and the frozen scallops A are transferred to this position, the frozen scallops A are discharged from the circumferential transfer path 65 so as to transfer to the rotating conveyor 70. At this time, since the circumferential conveying path 65 is rotating at a constant speed, the frozen scallops A on the conveyor 70 are arranged at predetermined intervals and transferred to the weighing process. In this way, when the rotary plate 60 rotates 2/3 and all the frozen scallops A in the pockets 64 of the circumferential conveyance path 65 are discharged, the frozen scallops A stored in the distribution chute 50 again.
Are supplied to each pocket 64. In this embodiment, the rotary plate 6
When 0 is rotated at 20 rpm, the frozen scallops can be quantitatively supplied at a pace of 300 to 400 pieces / minute in the weighing process by appropriately adjusting the timing of supplying the frozen scallops to the pockets of the circumferential transport path. .

FIG. 6 shows an example in which the irregular shaped material quantitative supply device 1 according to the present invention is incorporated in a weight selection process. Reference numeral 80 is a frozen scallop charging device, and the process equipment after the measuring process is conventional. Is the same as. The frozen scallop feeding device 80 is capable of lifting the frozen scallops stocked on the table 81 to a predetermined height by a stepped conveyor 82 having partition plates and feeding them into the feeding hopper 3 of the feeding device 1. The frozen scallops supplied by the charging device 80 are distributed as described above, and are supplied in a fixed amount in an aligned state in the measuring step 120. Further, the supply amount can be set arbitrarily, but a large amount of high-speed supply is possible. In the present embodiment, the apparatus has been described by taking a frozen scallop as an example, but it is needless to say that this application is not limited to frozen scallops and can be used for quantitative supply of various types of indefinitely-shaped fresh products.
