[Technical field to which the invention belongs]
The present invention is not limited to an automatic weighing method and apparatus, and particularly to an automatic fish weighing method and apparatus capable of weighing and distributing continuously supplied fish in a very short time.
[0002]
[Prior art]
Generally, a distribution system requires a process of weighing and distributing products to be weighed, such as products and products, and packing them into containers or containers. It has been.
When the article to be weighed is, for example, a fish, the fish unloaded from the fishing boat that entered the port at the loading port may be sold directly to a trader or may be temporarily stored in a freezer. However, in any case, it is common to weigh and distribute in a predetermined container. These operations are performed after weighing fish distributed from a hold to a belt conveyor and distributing it to a predetermined container. Stored in place by a conveyor. And in this case, if the work speed is slow and it takes a long time, the freshness of the fish will drop and it will be necessary to do it in a short time. At the same time, the container must have a predetermined amount of fish to be distributed. Don't be.
[0003]
In order to meet these requirements, the applicant of the present invention invented and commercialized an automatic weighing device based on the weighing method that had been used for a long time. Therefore, we invented an automatic weighing device that uses the volumetric method instead of the weighing method (see Patent Document 1) and has a simple automatic structure that enables accurate weighing in a short time. We have made a weighing device.
The configuration of this automatic weighing device (hereinafter referred to as the automatic weighing device in the patent) is as follows: “Weighed articles continuously fed through a hopper chute are provided with an inlet for the measured articles and an inlet to the container. In an automatic weighing apparatus for weighing in a weighing chamber and putting a predetermined amount of the article to be weighed into the container, the weighing chamber is centered on a pair of side plates parallel to each other and a rotation axis perpendicular to the pair of side plates.

[Problems to be solved by the invention]
Although the above automatic weighing apparatus was able to perform good processing in both processing speed and measurement accuracy for the processing of relatively small fish, As fish became a big problem, the damage of large fish due to cutting of fish during weighing, which was not a problem for small fish, became a major problem. Moreover, in recent years, there has been a growing demand for automatic weighing devices that can handle large-scale high-quality fish for raw consumption. In order to eliminate these problems, the present applicant has improved the automatic weighing device of Patent Document 1 and developed an automatic weighing device that does not cause damage to large fish (for details, see the description of the embodiment in FIG. 4-8).
[0006]
As a result, it was possible to measure without causing damage even in the case of large fish, but in terms of weighing accuracy, the user could not be satisfied sufficiently, and even in the case of large fish, no damage occurred. In addition, there is a need for an automatic weighing device that can perform automatic weighing quickly and accurately.
That is, at present, edible fish is generally shipped at a processing plant by placing ice and a small amount of water under a container such as polystyrene foam, and then placing the fish on top of it and shipping it out. In some cases, the water and ice contained in the container were supplied by eye examination, so it was impossible to measure the weight of the fish that had been cut and supplied by an automatic weighing device. And since the weight per volume differs depending on the size, freshness, etc., it was necessary to take out the fish after measurement and measure the weight. For this reason, a large fish with a high unit price per fish was put in a separate container, measured for its net weight, and then shipped to a customer in a container containing water and ice. Therefore, a method that can cope with such a case and can accurately measure the weight in a short time is required.
[0007]
The present invention addresses these situations and makes the most effective use of the automatic weighing device developed by the applicant to enable accurate and automatic weighing of large fish for raw consumption quickly and easily. It is an object of the present invention to provide a fish automatic weighing method capable of satisfying the above requirements, and a fish automatic weighing device that can be used in this method and that is simple in structure, easy to operate, and easy to maintain.

[0011]
First, the structure and operational effects of the automatic weighing means will be described with reference to FIGS.
4 and 5 show the structure of the measuring drum 22, and the measuring drum 22 has a main arc portion having a radius R1 (approximately the same length as the fish receiving port) with the measuring drum bearing 32 as the center of rotation. 22A And main arc 22A A subarc portion having a radius R2 that is connected to the lower end portion of the ring and has a point different from the radius R1 as a fulcrum 22B When the measuring drum 22 receives fish from the hopper chute 21, the upper part of the measuring drum 22 is fully opened, and at the lower part, as shown in FIG. 22A And a secondary arc portion of the tip locus R2 of the variable volume plate 22B Thus, the weighing drum 22 is configured.
A measuring space is formed by the measuring drum 22, the variable volume plate / parallel link 23, and the variable volume plate 24 with L-shaped link, and the variable volume plate with L-shaped link is operated by operating the volume adjusting handle 37. 24 is moved to adjust the volume of the measuring drum 22.
That is, this automatic measuring means mainly includes a hopper chute 21, a measuring drum 22, a volume variable plate 24 with an L-shaped link, a volume variable plate / parallel link 26, and a volume adjusting means (34-37) constituting a fish supply port. This is a component, and the volume adjustment means (34-37) adjusts the position of the volume variable plate with L-link 24 and the volume variable plate / parallel link 26 to adjust the volume in the measuring drum 22 to a predetermined value. In this state, the measuring drum 22 is reciprocated to lower the supplied fish by a predetermined amount into the lower container.
[0012]
Next, the state of measuring fish using the automatic measuring means of this embodiment will be described with reference to FIGS. FIG. 6 shows a case where the fish is small, FIG. 7 shows a case where a large fish is contained, (a1), (a2), (a3) show the case where the volume variable plate is set at a small volume position, (b1), (B2) and (b3) show the case where the variable volume plate is set at the large volume position. In any of the figures, (a1) and (b1) indicate when the fish is thrown in, (a3) and (b3) indicate when the weighing is finished, and (a2) and (b2) indicate intermediate states.
First, when the fish of FIG. 6 is small, as shown in (a1) and (b1), the fish level sensor 39 set in the hopper chute 21 in a state where the fish is supplied to the hopper chute 21. When it is detected that a predetermined amount of fish has been supplied into the measuring drum 22, the measuring drum 22 rotates as shown in (a2) and (b2), the opening on the hopper chute 21 side is closed, and the lower opening is large. Finally, as shown in (a3) and (b3), the hopper chute 21 is completely closed, and the fish in the measuring drum 22 is discharged out of the measuring drum 22.
And when the volume variable plate which consists of the volume variable plate 24 with L-shaped link and the volume variable plate parallel link 26 is set in the position of small volume, as shown in (a1), the fish level sensor 39 is a fish. As shown in (a2) and (a3), the measuring drum 22 rotates. At this time, the rotation is fast, so that the fish does not fall below the lower opening during opening and closing, and (a3) As shown, the fish falls when the rotation is near the open position.
That is, in (a1), the bottom of the hopper chute 21 is completely opened, and the bottom of the measuring drum 22 is also completely closed. When a certain time has passed in this state, the measuring drum 22 moves in the closing direction as shown in (a2), and the bottom of the measuring drum 22 is fixed to the measuring drum 22 and the volume variable plate 24 with the L-shaped link with the movement. The space between the rubber plate 26 and the rubber plate 26 is increased. However, even in this state, the fish are densely packed in the measuring drum 22 and the fish in the hopper chute 21 is also in a state of rising, so that it is fixed to the volume variable plate 24 with the L-shaped link of the measuring drum 22. Even if the gap between the rubber plate 26 and the rubber plate 26 is increased, the fish in the measuring drum 22 does not descend immediately, the hopper chute 21 of (a3) is completely closed, and the lower end of the measuring drum 22 is fully opened. It becomes a state.
When the variable volume plate is set at the large volume position, the fish level sensor 39 detects the fish as shown in (b1), and the weighing drum 22 as shown in (b2) and (b3). However, the fish does not fall below the lower opening during opening and closing, and the fish falls when the rotation is close to the open position.
In any case, the fish rises at the upper end of the weighing drum during the operation. This is thought to be because the fish cannot move in the measuring volume because the measuring time for one time is 1 second and the opening / closing operation time is about 0.3 seconds.
[0013]
Here, a mechanism for improving fish weighing accuracy when the apparatus of this embodiment is used will be described. Compared with the positive displacement measuring device described in Patent Document 1, this device is configured such that fish can be pushed into the measuring container. That is, in this apparatus, as shown in FIG. 6, a fish swell 41 is recognized at the measuring tip, but in this case, the fish swell 41 at the measuring tip is in the case of the positive displacement measuring device described in Patent Document 1. I was not able to admit. This is because the rotation angle of this device is about 60 degrees in the case of the positive displacement measuring instrument described in Patent Document 1, whereas this device can be set to about 90 degrees. If the operation time is the same, the upper opening is widened, and the fish enters the weighing drum at the upper part, and the operation becomes better. That is, in the case of the volumetric weighing device described in Patent Document 1, when the weight of the fish to be weighed is 350 grams or more, the fish starts to form a bridge at the entrance, and the time is 0.5 seconds (weighing once). In the case of this embodiment, for example, a mackerel of 350 g or more and 650 g that is shipped to a supermarket or the like can be weighed. . Since it can weigh 15 kg fish in 1 second, it can be processed quickly and the freshness of the fish will not drop.
In addition, in the positive displacement measuring device described in Patent Document 1, if the fish is large and the fish is vertically sandwiched at the upper position at the position where the lower weighing drum is closed, The distance between the lower opening and closing part was closer than the lower position where the fish was hanging, and it was sometimes dropped between the left and right measuring drums and the auxiliary gate. In this case, the cut fish could not be sold and had to be removed, but when using the automatic weighing means of this embodiment, it was not cut even if it was pinched underneath, Even if it is pinched, it can be stopped with a rubber cushion and the fish will not hurt.
[0014]
The case where the fish is large will be described with reference to FIG. 7. In (a1), (a2) and (a3), when the volume variable plate is set at the small volume position in this way, (b1), (b2) and (b3) Indicates the case where the variable volume plate is set at the position of the large volume.
When the variable volume plate is set at a small volume position, as shown in (a3), even if the fish 42 is vertically sandwiched at the drum closed position as shown in (a1), the volume is changed as shown in (a3). It is only sandwiched between the variable plate / parallel link 23 and the volume variable plate 24 with the L-shaped link, and is not cut. When the variable volume plate / parallel link 23 and the variable volume plate 24 with the L-shaped link are set at a large volume position, as shown in (b1), the fish 42 is vertically held at the upper position at the drum closed position. Even in this case, as shown in (b2) and (b3), since the measuring drum 22 is in the closed position before the fish 42 falls below the measuring drum 22, the fish is rarely caught.
[0015]
Next, the automatic weighing method of the present invention mainly composed of such automatic weighing means and the structure and operation effect of the apparatus used therefor will be described.
In this apparatus, as shown in FIG. 1, a container transport drive conveyor 1.2.3.5.6 is arranged in series on a conveyor mounting base 19, and among these, the container transport drive conveyor 2 4 and 4 are provided with weight measuring sections, and at the position of the container transporting drive conveyor 3, a fish weighing section 18 having a fish supply conveyor 11 provided thereon is provided, and the container transporting drive conveyor 5 is provided. A deficient fish supply conveyor 16 is provided at the top of the.
As shown in FIG. 2, a continuous supply conveyor 11 having a structure for continuously supplying fish is provided on the upper part of the container conveying drive conveyor 3. As shown in FIG. 3, a shortage fish supply conveyor 17 is provided and constitutes an automatic supply means in case of a shortage of fish, and the shortage fish supply conveyor 17 can feed fish one by one. The fish are weighed in advance and weighed in advance so that they can be supplied in sequence. That is, the deficient fish supply conveyor 17 has a structure in which a preselected fish of approximately the same weight is held during operation of the apparatus and is supplied to the container one by one as necessary. The outer guide 16 is provided so as to feed fish one by one into the container.
[0016]
Next, an embodiment of an automatic weighing method for weighing a certain amount of raw fish into a container using the apparatus as described above will be described.
A first step of supplying at least ice 10 out of a predetermined amount of ice and water into empty containers 9 that are continuously and sequentially fed;
A second step of measuring the tare weight of the container supplied with at least ice 10 out of ice and water in the first step in the tare weight measuring unit 7;
A third step of putting a target amount of fish into the container weighed in the second step by the automatic weighing means of the fish weighing unit 18;
A fourth step of measuring the weight of the container into which the fish is put in the third step in the tare and the supply fish weight measuring unit 8;
A fifth step of removing an excess amount of fish in the container when the amount of fish introduced in the third step exceeds the target amount;
A sixth step of supplying a predetermined number of fish corresponding to the deficient amount by the measured amount deficient supply amount conveyor 17 when the amount of fish introduced in the third step is less than the target amount;
Seventh step of holding the fish selected in advance in the sixth step and supplying them one by one to the container as needed
And
The third step is performed by the fish weighing unit 18 composed of the volumetric fish weighing means shown in FIGS. 2, 4 and 5, and the sixth step is performed using the shortage fish supply conveyor 17 shown in FIG. Done.
That is, in this method, since raw fish cannot be cut, the deficiency is supplied by replacing the deficiency with the weight of one animal. In other words, it is not time-consuming to measure and supply the weight of each animal. Generally, in the fish processing plant, the fish is sorted according to the size of the fish, and the same size fish is put in a container and sent out. On the other hand, in this embodiment, the weight of each animal is registered or selected in advance in the weighing computer, and the fish is counted and supplied by a fish compare that can supply the shortage one by one.
[0017]
That is, first, the weight of at least ice 10 out of ice and water in a container (such as polystyrene foam or cardboard) is measured and stored on the container transport drive compare 2 by the tare weight measuring unit 7, and the container transport drive is performed. On the conveyor 4, the weight of the container 9 containing at least ice 10 out of fish, ice and water is measured by the tare and supply fish weight measuring unit 8, and the net weight is measured by the difference. If the measured weight exceeds the target weight, the weight or number is displayed on the indicator or lamp, etc., and the human removes the fish from the container by converting the weight of the excess to the number of animals, and the weight is insufficient. Is supplied to the container in the same manner. When the weight is insufficient, if it is automatically supplied, supply the fish that can be supplied separately on the compare one by one and supply the shortage of fish in the number of animals. The fish is supplied according to the measurement result of the tare and the supply fish weight measurement unit 8. If the weight is insufficient, it may be supplied manually.
When the type or size of the fish changes, the volume of the hopper volume variable motor 12 is adjusted so that the volume becomes the optimum amount based on the measurement result of the tare and the feed fish weight measuring unit 4. Each conveyor can be measured in either case of measurement during stop or measurement during driving. By this method, the weight can be measured quickly and accurately, and processing can be performed several times faster than the conventional method.
On the other hand, in the patent quantifier using the auxiliary gate described in Patent Document 1, the fish does not fall unless the volume-variable plate is expanded to the maximum position, but when close to the upper closing, it opens at the lower part. Since the part becomes very wide, when we tried to weigh a large fish of 350 g or more, the opening of the measuring drum became large, and the error was further increased.
[0018]
As a method for changing the volume of the measuring chamber of the fish measuring section 18 by the variable volume plate, as shown in FIGS. 4, 5, 6 and 7, an example of a parallel folding link type is shown as an example. It is also possible to use a variable volume plate made of a single plate or a single plate. 8A and 8B are schematic explanatory views, in which FIG. 8A is a half parallel link structure shown in FIGS. 4 and 5, FIG. 8B is a middle link structure, (c-1), (c-2). ) Shows a structure made of a single plate. The parallel folding link type is used for a weighing instrument of 10 kg or more, the folding link type is used for a weighing instrument of 10 kg or less, and a single plate is used when the weighing adjustment range is small. When a single volume variable plate is used and the measured value is small, as shown in (c2), the upper opening is made narrower than about 90 °, and the position of the tip of the measuring drum 22 and the position of the hopper chute 21 are different. Like that. That is, when the rotation angle is about 90 degrees and the tip of the measuring drum is below the tip of the hopper chute, the weight can be measured quickly and accurately, and processing can be performed several times faster than the conventional method.
The volume required for the measuring chamber varies depending on the size of the fish, and therefore the variable adjustment range of the variable volume plate varies depending on the size. For large fish, the variable adjustment range of 120% or more is necessary. In this case, only the folded parallel link type can be manufactured.
[0019]
In the above embodiment, as shown in FIG. 1, after the tare weight is measured by the tare weight measuring unit 7, the target amount of fish is supplied by the fish weighing unit 18 on the container conveying drive conveyor 3, and then The tare and the fish supply fish weight measuring unit 8 on the container transport drive conveyor 4 measure the weight of at least ice 10 out of ice and water, and the container containing the fish. If the weight measurement in the container transport drive conveyor 4 is configured to measure the weight in the container transport drive conveyor 3 provided with the fish weighing unit 18, the number of steps can be reduced and the apparatus can be downsized. .
[0020]
As described above, in this embodiment, even a large fish can be handled without being cut, and there is a dislike that a measurement error becomes large in that a certain amount is put into a tare. It became possible to solve the point that became a big problem when dealing with.
That is, when the fish is vertically pinched at the upper position at the position where the weighing drum of the positive displacement type fish weighing means described in Patent Document 1 is dropped, the fish is pinched and cut between the auxiliary gate and the rotating drum when it falls down. In addition, when trying to weigh a large fish of 350 kg or more, the opening of the weigh drum becomes larger and the error becomes larger, but the error caused by such an automatic weighing device is a process of this embodiment. Can be removed. That is, in this embodiment, since a measurement step is provided in the process, if an excess or deficiency occurs at this stage, the amount is immediately detected, so the amount of fish in the container is determined based on the detection result. Because it adjusts, it can be finally set as the target value, it can be processed by adding, if it is insufficient, it can be processed by adding, and these operations can impair the measuring speed of the automatic weighing means of fish It can be implemented without any problem, and high-speed processing and accuracy can be ensured.
[0021]
