Embodiments of the present invention will be described below with reference to FIGS. The basic configuration for weight selection is the same as in FIGS. 6 and 7, and therefore the same reference numerals are used in the description. In the following description, the stocker used to implement the sorting target products into the bucket 2 and the specific configuration of the bucket 2 will be described.

As shown in FIG. 1 and FIG. 2, the bucket 2 is connected from the upper part to the lower part of the inlet port 15 in a tapered shape, and is connected to the lower end of the inlet port 15, and the outlet 16 is formed at the tip. And a long first tubular path 17 that is formed. The outlet 16 of the first tubular path 17 is closed by a lever 18 as a gate that regulates the passage of products to be sorted. The bucket 2 includes a fixed side 11, a movable side 12, and links 13a and 13b that form a link mechanism 19.
Of these, it is attached to the front side of the movable side 12. An intermediate portion of the lever 18 is pivotally supported by a shaft 20 on the movable side 12 and is rotatable, and is biased by a spring 21 in a direction of an arrow B, and a tip portion of the lever 18 closes the outlet 16 of the bucket 2. ing.

The eels to be sorted are automatically loaded into the bucket 2 by a stocker 22 as shown in FIG. A long second tubular path 24 is connected to the bottom corner of the stocker body 23. A gate 2 that can be opened and closed by an electromagnetic solenoid 26 is provided at a payout opening 25 of the second tubular path 24.
7 is attached. The energization of the electromagnetic solenoid 26 is controlled by the gate controller 28. The gate control unit 28 determines whether or not the sensor 29 has detected that the bucket 2 has arrived at a position below the payout opening 25 of the second tubular path 24, and the electromagnetic control is performed at the timing when the sensor 29 detects the bucket 2. The solenoid 26 is temporarily energized to open and close the gate 27.

With this configuration, when an operator manually feeds the eel 30 into the second tubular path 24, the eel 30 is held in the second tubular path 24 until the bucket 2 arrives. When the bucket 2 arrives, the gate 27 is opened and the eel 30 held on the second tubular path 24 is discharged. The eel 30 delivered from the stocker 22 is
The bucket 2 is slid and held in the first cylindrical path 17 through the wide-mouth inlet 15 of the bucket 2.

While the bucket 2 is traveling, it is regulated by the discharge control means so that it will not engage with the link mechanism 19 and swing downward until it reaches the corresponding discharge station. Specifically, as shown in FIG. 2 and FIG. 3, a part D of the link mechanism 19 engages with the back surface of the guide rail 10 or the back surface of the discharge triggers 8 ₁₀ to 8 ₄₀ , 8 ₁₁ to 8 ₄₁ and the bucket. 2 is held in a posture in which it does not swing, and the base end portion E of the lever 18 is not in contact with the fixed side support rail 31.

When the discharge triggers 8 ₁₀ to 8 ₄₀ , 8 ₁₁ to 8 ₄₁ and the part D of the link mechanism 19 are disengaged at the corresponding discharge station, the movable side 12 is moved to the position shown in FIG. The roller 14 abuts against the support rail 31 and is received by the support rail 31 by its own weight. At this time, lever 1
The base end portion of 8 contacted the support rail 31 and reliably rotated against the urging force of the spring 21 as shown in FIG. 5, and slid into the first cylindrical path 17 and held by the eel. 30 is discharged from the bucket 2.

In this way, the eel 3 placed in the bucket 2
Since 0 is held by sliding in the first tubular path 17, it can be reliably transported to the discharge station without escaping or dropping.

Further, since the gate of the bucket 2 is constituted by the lever 18, it can be held at the closed position by the spring 21 and abut on the support rail 31 to be opened, so that the bucket 2 is fixed to the fixed side. There is no need to supply power from.

In this way, the eel 30 can be easily placed in the bucket 2, and even if the eel 30 is not put to a nap, it can be transported to each discharge station for weight selection.
The eel 30 can be weight-sorted in good condition.

Further, since the eels 30 put into the bucket 2 are held by the first tubular path 17 and are difficult to run wild, the weighing machine 7 measures the eels 30 together with the bucket 2, so that accurate measurement is carried out. Therefore, it is possible to expect a great improvement in sorting accuracy.

In the above-mentioned embodiment, the base end of the lever 18 abuts the support rail 31 to open the payout opening 16 of the first cylindrical path 17, but it arrives at the corresponding discharge station. It is also possible to open the payout opening 16 by energizing an electromagnetic solenoid or a motor at times.

In the above embodiment, the gate control unit 28 opens and closes the gate 27 of the payout opening 25 of the stocker 22 by energizing the electromagnetic solenoid 26. However, a part of the gate 27 is engaged with the bucket 2 through which it passes. The gate control unit 28 and the electromagnetic solenoid 26 can be omitted by being configured to be opened and closed by an urging force such as a spring.

In the above embodiment, the weight was measured by the weighing machine 7 when the articles to be sorted were put into the bucket 2. However, the weight was measured at each discharge station and the measured value was measured at each discharge station. The present invention is also effective in the case of a configuration in which the sorting target products are discharged from the bucket 2 when the weight falls within a predetermined weight range. Further, in this case, the comparison operation between the weight at each discharge station and the weight range determined for each discharge station is not limited to the electric type, and the weight determined for each discharge station at one end of the lever is not limited. When the set weight is loaded and the weight of the bucket 2 into which the item to be sorted is loaded is loaded on the other end of the lever and falls within the weight range determined for each discharge station, the item to be sorted from the bucket 2 is selected. The same effect can be expected in the case of a mechanical balance type configured to dispense.

[0030]

According to the structure of claim 1, a long cylindrical path having a dispensing opening formed at its tip is connected to the bottom of the stocker main body into which the products to be sorted are put, and the cylindrical path has the above-mentioned structure. Since the gate for restricting the passage of products to be sorted is provided at the outlet, the products to be sorted that slipped into the long tubular path of the stocker body are held by the gate provided at the outlet of the tubular path, When the bucket arrives at a position below the outlet of the route, the long fresh fish can be put into the bucket by opening the gate.

According to the second aspect of the present invention, the gate control unit can detect the bucket, open the gate, and automatically insert long fresh fish into the bucket. According to the structure of claim 3, since the bucket is composed of the narrowed insertion port and the long tubular path connected to the lower end of the insertion port, the sorting target products are loaded from above. It is received by a tapered inlet toward the bottom and held by sliding in a long tubular path, so that the sorting target product does not run away, escape or drop. At the discharging station, the gate is opened and the products to be sorted are discharged from the long tubular path.

According to the structure of claim 4, when the bucket arrives at the corresponding discharging station and swings downward, the base end portion of the lever abuts on the support rail, and the lever is rotated to clear the bucket. The outlet is open, and you can expect a reliable operation with a simple structure.
