Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight measuring device capable of measuring the weight of fish, such as sardines and horse mackerel, agricultural products, industrial products, and the like, and automatically sorts fish such as sardines and horse mackerel by flow work. The present invention relates to a fish sorting apparatus capable of distinguishing by weight, appearance, color, and the like.

[0002]

2. Description of the Related Art Niboshi is closely related to Japanese eating habits, and sardines and other small fish are used as raw materials. Conventionally, for example, the following method has been used to produce sardines from sardines. 1. Wash the sardines with water. 2. The washed sardines are sorted by a roller sorter and the sizes are roughly adjusted. 3. Put the sardines in the bowl. 4. Boil the sardines in the pot with the water. 5. Dry the boiled sardines together with the sun. 6. The sardines are further dried in a dryer to make the dried sardines. 7. The dried sardines are sorted by size, weight, shape and color before being shipped to the market.

[0003] In order to ship niboshi as a commercial product, it is necessary to carry out various sorts. The selection items are the size of the size, oil paste, peeling, presence or absence of cracks in the belly, and the like. Boiled dried noodles which are regarded as good products have a weight of 5 g or less, and those of 6 to 7 g are re-dried so as to have a weight of 5 g or less, and products having a weight of 6 g or more cannot be regarded as good products. In addition, the surface of the good-quality boiled dried fish is pale and the surface is not cracked.
The belly is not broken. The surface is oil-burnt and turns yellow (oil paste), the surface cracks and peels off (peeling off), the belly cracks and the body turns red and black (belly cracking)
Those that do are considered defective. In particular, if the oil paste or the dried boiled dried product is mixed into the dried boiled good product, the oil of the dried dried boiled product will be transferred to the good product, and even the good product will be burnt with oil and become discolored. Therefore, the work of sorting good and bad boiled anchovies is important because it affects the quality of boiled anchovies and affects the selling price.

[0004]

(Embodiment of Weight Measuring Apparatus) FIG. 4 shows an embodiment of a weight measuring apparatus according to the present invention. The illustration shows a case where the object 1 is dried. This weighing device is provided with a gutter-shaped weighing plate 35 made of metal, resin, or the like.
7, the tip side is supported to be rotatable up and down, and the boiled dish is automatically tilted down to the angle at which it can automatically slide down by its own weight. I have. When the broth passes over the weighing pan 35 (about 1/1000 second during this time), the weight measurement sensor 36 lowers the tip side of the weighing pan 35 by the weight of the broth 1 and automatically measures the weight of the broth. It is like that.

In front of the weighing pan 35, a receiving pan 34 for receiving the dried sardines 1 sent from the dispersion conveyor 3 is arranged. The saucer 34 is for reducing the shock when the dried broth 1 falls from the dispersion conveyor 3, and is sent from the saucer 34 to the weight measuring unit 6 on the same surface to thereby measure the measuring dish 35.
Is to prevent vibration. Incidentally, if the dried broth 1 falls directly from the dispersing conveyor 3 to the weight measuring section 6, the weight measuring section 6 vibrates, causing an error in the measured value or taking a long time for the measurement.
When the dried noodles 1 are fed into the oven, the vibrations are eliminated and quick and accurate measurement can be performed.

As shown in FIG. 4 (b), a gutter-shaped weight sorter 7 made of metal or resin, which is formed separately from the weighing dish 35, is disposed in front of the weighing dish 35. The weight sorter 7 sorts the dried noodles 1 based on the measurement result by the weight measuring unit 6. Therefore, the weight sorter 7 is shown in FIG.
As shown in (b), it is rotatable by a driving device (not shown) from a state in which it is lowered forward and inclined horizontally to a horizontal position in which it is flush with the weighing pan 35. When the weight of the dried broth 1 measured by the weight measuring section 6 is a non-defective value, the weight selector 7 returns to the horizontal position, and the dried broth 1 sliding down from the weighing pan 35 passes over the weight separator 7. If the weight of the dried noodles 1 is out of the non-defective value, the dried noodles 1 are sloping down and slide down from the weighing pan 35, and fall down from the weight sorter 7 sideways. They are sorted out as defective. As an example, 5 g
In the following cases, the weight sorter 7 does not rotate but remains horizontal and passes thereover as a non-defective product, and is located on the left side of the alignment plate 41 on the conveyer 40 disposed ahead as shown in FIG. Sent to. If it is heavier than 5 g, the weight selector 7 is turned to the lower right as shown in FIG. 4 (b), and the broth 1 is sent to the right side of the aligning tool 41 on the conveyor 40 as shown in FIG. It is.

FIGS. 4 and 5 show the case where the weight measuring section 6 and the weight selector 7 are arranged in one set (one row). It is also possible to measure and sort the dried sardines 1 sent out in two horizontal rows by the sorter 7. In addition, the weight measurement unit 6
And the weight selector 7 are provided in two stages, and the first set of the weight measuring unit 6
And the weight sorter 7 divides the dried broth 1 to 7 g or less and the dried broth 1 to 8 g or more. The dried broth 1 to 7 g or less is boiled to less than 5 g by the second weight measuring section 6 and the weight sorter 7.
g of dried noodles 1 and 5 g or less of dried noodles 1 can be sent to the next stage as good products. In this case, since the one-row broth 1 is measured and sorted in two stages, the sorting accuracy is improved. The dried broth 1 classified to 6 g to 7 g in the previous weighing / sorting can be dried again to reduce the weight, and then weighed again to obtain a good product.

(Embodiment of Automatic Fish Sorting Apparatus) An embodiment of an automatic fish sorting apparatus according to the present invention will be described with reference to FIGS. This embodiment is a case in which the material to be sorted is a dried noodle 1. As shown in FIG. 1, the conveyor 2, the dispersion conveyor 3, the sorting space 4, the aligning tool 5, and the weight measuring unit 6
, Weight sorter 7, image processing unit 8, appearance sorter 11
And

The conveyor 2 shown in FIG. 1 is a belt conveyor, which is provided inside a frame 21 having legs 20 and is rotated by a drive source such as a motor. The transport conveyor 2 transports a large amount of dried noodles 1 opened from a container. Two or more conveyors 2 can be arranged in the conveying direction. In this case, the transport conveyor 2 on the downstream side in the transport direction is lowered by one step from the transport conveyor 2 on the upstream side in the transport direction, and the dried dried fish 1 transported by the upstream transport conveyor 2 is taken over by the downstream transport conveyor 2. To be transported.

The dispersion conveyor 3 shown in FIG. 1 is also a belt conveyor, rotatably provided inside a frame 21 having legs 20, and rotated by a drive source such as a motor. The dispersing conveyor 3 conveys many dried noodles 1 conveyed by the conveyor 2 while dispersing them in the conveying direction and the lateral direction of the conveyor 3. In FIG. 1, three dispersion conveyors 3 are arranged at intervals in the transport direction,
The first-stage dispersion conveyor 3 on the upstream side in the conveyance direction is inclined downward toward the upstream side, and the upstream end 3a is set on the conveyance conveyor 2.
In this case, the dried noodles 1 conveyed by the conveyor 2 drop onto the first stage dispersion conveyor 3 and are conveyed. In addition, the second and third dispersion conveyors 3 are also inclined downward so that the upstream end 3a is lowered, and the dried sardines 1 conveyed by the upstream dispersion conveyor 3 sequentially fall onto the downstream dispersion conveyor 3. So that they can be taken over.

The rotation speed of the three dispersion conveyors 3 is set to be higher than that of the upstream dispersion conveyors, and each time the dried sardines 1 are taken over from the upstream dispersion conveyors 3 to the downstream dispersion conveyors 3, they are conveyed at a high speed and are conveyed in the conveying direction. It is made to disperse. Each of the dispersion conveyors 3 is horizontally arranged as shown in FIG. 2, the downstream dispersion conveyor 3 is one step lower than the upstream dispersion conveyor 3, and the broth 1 conveyed by the upstream dispersion conveyor 3 is downstream. It can also be automatically dropped on the distribution conveyor 3 and taken over.

As shown in FIG. 2, four aligners 5 are arranged on each dispersion conveyor 3. The aligning tool 5 is for dispersing the broth 1 conveyed on the dispersion conveyor 3 in a line during conveyance. The alignment tool 5 is suspended by a support bar 26 from a downward U-shaped alignment tool mounting tool 25 arranged on the frame 21 as shown in FIG. In this case, the bottom surface of the alignment tool 5 is slightly elevated above the top surface of the distribution conveyor 3.

A large number of broths 1 conveyed in a vertical direction (head and tail in the conveying direction) on each of the dispersing conveyors 3 are scattered in the width direction of the dispersing conveyor 3 when they hit the aligning tool 5. Then, each aligning tool 5 is dispersed one by one or several by one, and the dispersion is performed in each of the first, second and third dispersion conveyors 3. Since the traveling speed of the dispersion conveyor 3 becomes higher as it goes to the second and third stages, as the second and third stages of the dispersion conveyor 3 become, the broth 1 is gradually dispersed in the transport direction, and the third stage (final) In the dispersion conveyor 3 of (stage), they are dispersed one by one. If the individual conveyors are not dispersed one by one even if they are conveyed by the final stage dispersion conveyor 3, the number of dispersion conveyors can be increased to four or five.

The first-stage dispersion conveyor 3 and the second-stage dispersion conveyor 3, and the second-stage dispersion conveyor 3 and the third-stage dispersion conveyor 3 are arranged with a gap therebetween.
The sorting space 4 is opened in four rows in the transfer plate 27. Each sorting space 4 has vertical and horizontal dimensions to be sorted (sorting dimensions), and the dried sardines 1 smaller than that size fall from the sorting space 4 and fall therefrom. It allows you to pass. Without providing the transfer plate 27 in the gap of the dispersing conveyor 3, the gap itself may be used as a selection dimension so that the dried broth 1 that is shorter than the gap falls from the gap and only the broth 1 that is longer than the gap can pass through. it can. In this case, the gap becomes the sorting space 4. The length or width of the sorting space 4 can be adjusted to change the length of the dried broth 1 to be sorted. The adjustment can be performed, for example, by providing a plate-shaped shutter on the back side of the transfer plate 27 and opening and closing the shutter. The dried broth 1 that has fallen from the sorting space 4 slides down on the shooter 30 shown in FIGS. 1 and 2 and falls onto the discharge conveyor 31 below the sorting space 4, and thereby the transport conveyor 2
Then, it is sent to the outside of the side of the dispersion conveyor 3 and collected in a collection container 38 such as a cardboard box provided below the outlet of the discharge conveyor 31.

The dried noodles 1 that have passed through the sorting space 4 are taken over by the second-stage dispersion conveyor 3. In this case, the speed of the first-stage dispersion conveyor 3 is lower than the rotation speed of the second-stage dispersion conveyor 3.
, The boiled dried fish 1 on the second-stage dispersion conveyor 3 does not cling, but is scattered in the transport direction. Similarly, the dried noodles 1 are transferred from the second-stage dispersion conveyor 3 to the third-stage dispersion conveyor 3. Since the rotation speed of the third-stage dispersion conveyor 3 is higher than that of the second-stage dispersion conveyor 3, the dried noodles 1 are not separated and conveyed apart. Four aligning tools 5 are also arranged on the third-stage dispersion conveyor 3, and the dried noodles 1 are transported in four rows by the aligning tools 5.

A transfer plate 27 is also provided above the gap between each of the dispersion conveyors 3, and a separation space 4 is opened in the separation plate 27 so that the length of the broth 1 sent from the upstream dispersion conveyor 3 can be selected. Only those longer than the dimensions pass through the sorting space 4,
Those that are shorter than the screening dimensions are taken from the screening space 4 to the shooter 32.
, Slides down on the shooter 32, is sent to the discharge conveyor 31, is sent to the outside of the side of the transport conveyor 2 and the dispersion conveyor 3, and is provided with a cardboard box or the like provided below the outlet of the discharge conveyor 31. Collected in the collection container 38.
Also in this case, without providing the handover plate 27 in the gap of the dispersion conveyor 3, the gap itself is used as a selection dimension, and the dried sardines 1 shorter than the gap fall from the gap, and the dried sardines 1 longer than the gap.
Only the gap can be passed over the gap.
The spacing of the sorting space 4 can also be adjusted.

As shown by phantom lines in FIGS. 1 and 2, a plate-like separator 33 is provided at the center of the discharge conveyor 31 along the longitudinal direction thereof.
If it is set up, boiled fish 1 dropped from the sorting space 4 between the first and second dispersion conveyors 3, and boiled fish 1 dropped from the separation space 4 between the second and third dispersion conveyors 3 Can be separated on a single discharge conveyor 31 by a separator 33, transported separately, and collected separately.

The dried broth 1 conveyed and collected by the discharge conveyor 31 is treated as a good product in terms of dimensions. However, some of them are bent, cracked, or covered with oil. Are visually selected.

The dried noodles 1 dispersed in four rows by the third-stage dispersion conveyor 3 are slid down to the receiving tray 34 shown in FIG. The tray 34 is for reducing the shock when the dried broth 1 falls from the dispersion conveyor 3 and for preventing the tray 34 from vibrating by being sent from the tray 34 to the weight measuring unit 6 on the same surface. is there. By the way, if the dried broth 1 falls directly from the dispersion conveyor 3 to the weight measuring unit 6, the weight measuring unit 6 vibrates, causing an error in the measured value or taking a long time for the measurement. When the dried broth 1 is sent in, the vibrations are eliminated and quick and accurate measurement can be performed.

The weight measuring section 6 has a structure and a function described in paragraph number “0010”. In the weight measuring unit 6, for example, when the dried broth 1 is 5 g or less (good product), the weight sorter 7 remains horizontal without rotating and passes over it, and is disposed at the tip as shown in FIG. It is sent out to the left side of the alignment plate 41 on the conveyor 40 that has been moved. If the weight is more than 5 g (defective product), the weight selector 7 is rotated so as to be inclined downward to the right in the conveying direction as shown in FIG. 4B, and the broth 1 is arranged on the conveyor 40 as shown in FIG. It is sent out to the right side of the tool 41. As shown in FIG. 6, 5 g or less of good quality dried noodles 1 is sent from the conveyor 40 to the next conveyor 50. In this case, if the direction of the conveyor 40 is arranged orthogonal to the conveyor 50, the dried noodles 1 can be easily aligned on the conveyor 50 in a fixed direction (head-first direction).

A conveyor 51 is arranged at the end of the conveyor 50, and a conveyor 52 is arranged at the end of the conveyor 51, so that the fishes are conveyed by them. These conveyors 50, 51, 52 are motors 53, 54, 55 shown in FIG.
Is rotated with the drive source. Also in this case, the conveyor 50, 5
If the rotation speed of the first and the 52 is faster in the arrangement direction, the fishes are dispersed in the transport direction each time the conveyors 51 and 52 take over.

At both upper sides of the conveyor 50 shown in FIG. 6, CCD cameras 9 are provided as shown in FIGS. The CCD camera 9 forms an image processing unit 8 with an appearance determining unit 10 as shown in FIG. The two CCs shown in FIG.
The dried broth conveyed on the conveyor 52 by the D camera 9 is photographed from two directions (back side and abdominal side). If this camera 9 uses a camera that can release the shutter 60 times or more per second, it is possible to take a constrained image, and even if the transport speed of the drying by the transport conveyor increases, it is possible to reliably capture the fish without missing. The captured image of the dried sardines is the appearance determination unit 10
From FIG. 9, for example, it is possible to determine the appearance of the dried sardines such as cracks in the belly, peeling, and gloss (the glossy one has oil paste). The appearance is also displayed on the monitor TV (monitor TV) 70 shown in FIG. 9, and the user can visually check the monitor TV 70. The result of the determination by the appearance determination unit 10 is transmitted to the appearance selection unit 11 shown in FIG.

The appearance selection section 11 shown in FIG. 10 is provided at the front of the CCD camera 9 and behind the monitor TV 70. A plurality of nozzles 60 are used in the appearance selection unit 11. The appearance of these nozzles 60 is discriminated by the appearance discriminating unit 10, and compressed air is blown on the dried noodles conveyed on the conveyor 56. , Belly cracks, oil paste, etc.) are discharged to separate collection containers (for example, cardboard boxes) 61 shown in FIG. These collection containers 61 are placed on rollers 62 as shown in FIG. 7, and when they are full, they are slid on the rollers 62 and sent out in the lateral direction of the conveyor 56. Is installed.

(Embodiment 2) In the embodiment 1 shown in FIG. 2, the V-shaped aligning tool 5 is arranged on the horizontal conveyor 2, but as shown in FIG. If it is installed diagonally downward in the width direction, it is not necessary to install the aligning tools 5 in a V-shape. Therefore, the aligning tools 5 are arranged at the same interval on the conveyor 2 having the same width as in FIG. Even so, more aligning tools 5 can be arranged (4 in FIG. 2).
Book, and five in FIG. 11). Similarly, if the distribution conveyor 3 is also installed obliquely with respect to the frame 21, the number of the alignment tools 5 can be increased. By doing so, the number of simmered rows that can be sorted at a time is increased, and the efficiency of sorting is improved.

(Embodiment 3) FIGS. 2, 11 (a) and 11 (b)
Then, the alignment tool 5 is placed on the transport conveyor 2 and the dispersion conveyor 3.
Are arranged to arrange the dried noodles. However, if the desired number of rows (for example, four rows) of the conveyer 2 and the dispersion conveyor 3 are provided as shown in FIG. 12, the arrangement plate 5 becomes unnecessary.
Also in this case, if the rotation speed of the first, second, and third-stage dispersion conveyors 3 is gradually increased, the fishes can be transported in a line while being dispersed in a desired number of lines.
