Description

Detailed Description of the Invention (a1 Technical Field of the Invention The present invention relates to an automatic boxing device that packs fresh fish of variable weight into boxes of a predetermined weight, and is particularly capable of efficiently packing a predetermined weight of fish into boxes. Regarding automatic packaging equipment.

(Background of BL technology) When fresh fish is packaged and shipped by predetermined weight, in order to maintain freshness and increase productivity, it is necessary to ensure permissible weight accuracy and to perform quick packaging processing. , automatic packaging equipment is in demand.

(C) Prior Art and Problems Conventionally, when fresh fish is packed into boxes, it is done manually, and in order to maintain freshness, the work is done by a large number of people in a short period of time.

Therefore, when packing boxes of a specified weight, the method used is to place the box on a scale, fill the box with fresh fish until the specified weight is reached, and then send the box out when the specified weight is reached. There is.

In this case, increasing the weight accuracy will slow down the work speed,
If the work is done in a hurry, the weight accuracy will deteriorate, which is incompatible, so there is a disadvantage that efficiency is poor, and there is also a disadvantage that it requires more manpower.

For this reason, there is a strong demand for automatic packaging equipment that has high weight accuracy and high packaging speed.

fd1 OBJECTS OF THE INVENTION The purpose of the present invention is to meet the above-mentioned needs, and to provide an automatic boxing device for indefinite weight items that has good M quantity accuracy and can be boxed quickly.

te+ Structure of the Invention The present invention provides a plurality of storage means for storing one or more of the packed objects to be packed, a weighing means for measuring the weight of the packed objects to be packed stored in the storage means, and a weighing device that is weighed by the weighing means. Record the weight data 1. 1. Storage means for a. The present invention is an automatic box packing device characterized by comprising a counting means for combining weighing data obtained by weighing a and calculating a predetermined weight, thereby achieving the object.

(Embodiment 1 of the f1 invention) An embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. This figure is a plan view showing a part of the switching case 1- in FIG. 1, FIG. 3 is a block diagram of FIG. 1, and FIG. 4 is a flowchart of FIG. 1.

In Figure 1, 1 is Conhair, 2 is fresh fish, 3a to 3
Reference numeral d indicates a switching game 1., 4 indicates a packaging section, 11 to 19.31 to 39 indicate a general feed path, 21 to 29 indicate a store, and 21a to 29a indicate a store gate.

The fresh fish 2 is continuously conveyed on the conveyor 1 in the direction indicated by the arrow in the figure.

The switching gates 3a to 3d are switched in order to send the transported fresh fish 2 one section at a time to the transportation paths 11 to 19.As shown by the two-dot chain line in FIG. 2, first, the switching gates 3a are switched in the direction of the arrow. The routes are divided into three routes by the operation of gate magnets, which will be described later, and further divided into three routes by switching games 1-3b to 3d (not shown). A store 21 is located at the terminal end of the transport paths 11 to 19.
to 29, respectively.

The stores 21 to 29 temporarily store the fresh fish 2 sent IM through the transport paths 11 to 19, and are also equipped with weight scales 61 to 69, which will be described later, for weighing.
Furthermore, storage games 1.21a to 29a are provided.

The transport paths 31 to 39 are connected to the store gates 2]a to 29, respectively.
The starting point is a, and the terminal end is centrally connected to the packaging section 4.

The conveyance paths 11 to 19 and the conveyance paths 31 to 39 are constantly driven, and the fresh fish 2 is immediately conveyed by operation of the switching gates 3a to 3d or the store gates 21 to 29.

In FIG. 3, 5 is a main control unit, 6 is an amplifier, 7 is a memory, 8 is a counter, 9 and 10 are magnet drivers, 6
1 to 69 indicate weight scales.

The amplifier 6 amplifies the weighing data signal measured by the weight scales 61 to 69 and sends it to the main control section 5.

The memory 7 has storage areas corresponding to the weight scales 61 to 69, and stores weighing data sent from the main control section 5 in the corresponding storage areas.

The counter 8 is a subtraction counter that stores a predetermined weight, that is, the weight M to be packaged (\10 kg), and each store 2
Weight of fresh fish 2 stored in 1 to 29.

That is, it has a function of combining the weighing data stored in the memory 7 to count up to a predetermined weight, that is, 10 kg, and sending a signal to the main control section 5 when the counting is completed.

In this method of counting combinations of weighing data, main combinations are made in the serial number order of stores 21 to 29, and when a predetermined weight is approached, a selection is made to adjust the weight to a predetermined value and the combination is made.

Then, the next combination starts from the weighing data of the store next to the main combination. Once the metric data in the store 29 is used in the main combination, the metric data in the store 21 is circulated.

In this way, the fresh fish 2 are evenly used for counting so that they do not stay in any of the stores 21 to 29 for a long time and lose their freshness.

The magnet drive 9 gives a drive signal to the corresponding gate magnet GM based on the selection signal from the main control unit 5,
Switching game) Performs switching control of 3a to 3d.

The magnet driver 10 provides a drive signal to the corresponding gate magnet GM based on the selection signal from the main control section 5, and controls the opening and closing of the store gates 21a to 29a.

Weigh scales 61 to 69 measure the weight of 20 fresh fish stored in stores 2 to 29.

With such a structure and function, when performing boxing work, as shown in FIG.
! It passes through the feed paths 11 to 19 and is stored in stores 21 to 29.

Then, the weighing scales 61 to 69 are operated to measure the weight of the fresh fish 2 and send the data to the main control section 5 via the amplifier 6.

The sent weighing data is stored in storage areas of the memory 7 corresponding to the weight scales 61 to 69.

Next, when the counter 8 combines the weighing data stored in each storage area and counts up to 10 kg, a signal is output, and one or more of the store gates 21a to 29a corresponding to the weighing data used in the combination opens and stores the weighing data. The fresh fish 2 that has been stored is transported, stored in a box (not shown) in the box packing section 4, and shipped in the direction of arrow B in the figure.

When any of the store games 21a to 29a is opened and the fresh fish 2 is sent out, the weighing data used for the combination in the memory 7 is cleared and the counter 8 is reset.

Fresh fish 2 are subsequently stored in empty stores 21 to 29 by switching the switching gates 3a to 3d.

In this case, the method of combining the weighing data stored in the memory 6 using the counter 8 will be described in detail. 1.8.2.0.2.1.2.2.2.1.1.9.1
．． 8.2.0.2.1 kg, first, the counter 8 is 10-1.8-2.0-2.1-2.2 =
The weight is 1.9 kg, and the next weight is 2.2 kg, so subtracting this will result in a negative value, which exceeds 10 kg, so 1.9 kg is selected from the remaining weighing data to make it 10 kg. That is, stores 21 to 24 and 27 are combined.

Therefore, the store gates 21a to 24a and 27a are opened, and the stored fresh fish 2 is sent out.

If an appropriate value cannot be obtained from the remaining measurement data, that is, the measurement data is 1.8.2.0.2.1.2.2.2.1.2.0.1
．． 8.2.0.2.1kg, then 1.9kg
For example, remove the last weighing data 2.2 kg from the combination, add the next 2.1 kg to the combination, and get 10-1.8-2.0-2.1-2.1-4.0 kg.
2.0 kg is selected from the remaining weighing data.

From such a combination of measurement data, it is inevitable to
If the weight does not reach 0kg, for example, subtract the weighing data from stores 21 to 24 and store the weight data from store games 1-21a to 2.
Open 4a, send out fresh fish 2, and return to stores 21 to 24.
The weighing data is used to subtract the weight, and when the weight reaches a predetermined value, the corresponding store game 1 is opened and sent continuously.

In such a procedure, if a slight allowable error (for example, about +0.2 kg) can be accepted for 10 kg, the calculation can be completed quickly.

Fresh fish 2 stored in stores 21 to 29 in this way
The weighing data of the weights are combined and packed as a predetermined weight of lokg.

Therefore, the fresh fish 2 that is continuously supplied in a fluid manner is transferred to the conveyor 1.
The food is stored in the stores 21 to 29 without being accumulated at the end of the container, and storage stagnation can be prevented, so the freshness does not deteriorate, the food is processed quickly, and the predetermined weight can be packed in boxes with high precision. .

In the above example, the weight of the fresh fish 2 stored in each store 21 to 29 is set to be approximately the same weight, and the weights that vary with respect to that target are combined to obtain a predetermined weight, but other methods may also be used. For example, a method as shown in FIG. 5 may be used.

That is, in FIG. 5, stores 41 to 46 are provided,
The store 41 has a large capacity, for example, the predetermined box weight is 10
kg, the capacity should be approximately 7 kg. Each of the stores 42 to 46 has a capacity of about 1 kg, and is configured to store objects in an inclined manner from a target larger than 1 kg to a target smaller than 1 kg by controlling the opening/closing timing of a switching gate (not shown).

Such weight adjustment is possible when the fresh fish 2 is a small fish.

The stores 41 to 46 are respectively equipped with store gates 41a to 46a and weight scales (not shown).

That is, as an example of measurement data, 6.8.1.3.1.1.10.0.9.0.8 kg
Then, the count is ] 0-6.8 = 3.2 k
g, and from the later measurement data, 1.3.1.0.0
．． Select 9 kg or 1.3.1.1.0.8 kg to make the predetermined 10 kg. In this case, the same effect can be obtained by reducing the number of stores and weight scales.

In addition, although the above example describes an example of an automatic boxing device for fresh fish 2, similar effects can be obtained by generally applying it to boxing a predetermined weight of other continuously supplied indefinite weight items. Of course.

(g) Effects of the Invention - As explained, according to the present invention, by combining the weighing data of undefined quantities of packaged objects stored in a plurality of stores, it is possible to Since packing can be performed automatically, ■Weight accuracy can be improved.

■Boxing is done quickly.

■Does not require manpower.

This has the effect of increasing efficiency.
