Description

[0001]
[Industrial applications]
The present invention relates to a series of egg processing systems that range from egg washing, drying, posture alignment, egg inspection, weighing, and sorting by size based on weight. The present invention relates to a device for spraying a spraying liquid such as a freshness maintaining liquid or a disinfecting liquid.
[0002]
[Prior art]
Conventionally, during the operation of the egg processing system, the application device such as a rotating brush is also operated, and before the weighed eggs are transported one after another, by the application device, to all the eggs regardless of size, The freshness maintaining liquid was applied. This freshness retention liquid includes liquid paraffin, mineral oil, vegetable oil, silicon grease, amine alginate, polystyrene, butadiene styrene, methacrylic resin, coumarone styrene, butyric rubber, polymethacrylic acid, acrylic resin, polyvinyl acetate, polyvinyl alcohol, etc. Is used. In addition, a food emulsifier that becomes a film when dried is used.
[0003]
In some cases, disinfectants such as ethanol and fatty acid esters are put into washing water to simultaneously perform egg washing and sterilization.
[0004]
However, unlike chicken eggs packed for retail or commercial use that need to maintain freshness, for example, eggs for liquid eggs that are used as whole eggs and are out of the size of retail or commercial eggs are After the weighing, the eggs are broken immediately by an egg breaking machine connected to the system, so that there is no need to apply or sterilize a freshness maintaining liquid. Therefore, it may not be necessary to apply or sterilize the freshness preserving liquid to all the eggs. Further, the application of the freshness maintaining liquid by the rotating brush was extremely inefficient.
[0005]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to provide a control mechanism of a series of egg processing systems with a spray mechanism so as to efficiently spray a freshness retaining liquid or a disinfecting liquid on all sizes or only selected sizes. It is in.

The embodiment of FIG. 1 shows a spraying mechanism A for spraying a spraying liquid W such as a freshness preserving liquid or a disinfecting liquid onto chicken eggs using compressed air, and a spraying control mechanism B for controlling the same.
[0008]
First, the known spraying mechanism A will be described. The spraying mechanism A includes a series of egg processing systems, for example, egg washing, drying, and posture alignment of the eggs that are successively conveyed from a supply conveyor (the sharp ends of the eggs are fixed in a certain direction). To facilitate the processing of the next step), a series of egg processing systems such as visual egg inspection, weighing, and sorting by size, etc., which are installed between the egg inspection step and the separation step.

Numeral 10 denotes an inner container installed in the outer container 9 with a lid, in which the spray liquid W is stored. Numeral 11 denotes a liquid supply pipe, which supplies the liquid W for spraying in the inner container 10 to a pair of spray guns 2 through a hose 12. As the spraying liquid W, a freshness maintaining liquid such as liquid paraffin described above or a disinfecting liquid such as ethanol is selectively used.
[0012]
FIG. 2 shows the arrangement of the spray gun in the egg processing system. 13 is a frame, 14 is a rail attached to the frame 13 via a support member 15, 16 is a chain that slides on the rail 14 and rotates endlessly, and 17 is a chain. The egg E is supported by an openable / closable bucket attached to the numeral 16. The chain 16 and the cup 17 constitute a bucket conveyor (pocket conveyor).
[0013]
The pair of spray guns 2 are installed above the eggs E, and spray the spraying liquid W evenly on the eggs E. Reference numeral 18 denotes a liquid avoiding plate provided above the chain 16 , 19 denotes a liquid receiving plate provided below the bucket 17, and 20 denotes a liquid receiving box.
[0014]
Next, the spray control mechanism B will be described.
As shown in FIG. 1, the spray control mechanism B utilizes a system control mechanism of the egg processing system, and includes a meter using a load cell, a CPU (central control unit), and a one-shot circuit with a timer. It is composed of The scale and the one-shot circuit are connected to a CPU, and the operation valve 8 is connected to a one-shot circuit. Note that it is also possible to install a CPU dedicated to the spray control mechanism B without using the CPU of the system control mechanism.
[0015]
In the egg processing system, the measuring device detects the weight of the sent egg and sends a size detection signal to the CPU. The CPU sends a discharge signal to a sorter that separates into a predetermined size according to the weight within a certain range while controlling the discharge timing based on the size detection signal, and a predetermined stocker arranged for each size. This is to discharge chicken eggs.
[0016]
According to the present invention, the CPU receives the size detection signal from the measuring device, and converts all the eggs of a predetermined size, for example, all the eggs of 20 g or more, or the eggs of a fixed size only, that is, the selected size ( It is controlled to spray the eggs of the selected weight value).
[0017]
Further, based on the size detection signal, the CPU controls the timing of spraying the eggs in accordance with the movement of the bucket conveyors 16 and 17 and sends them to the one-shot circuit as spray signals. The one-shot circuit with the timer receives the spray signal from the CPU and controls one spray (one-shot) time at a preset timing. Then, a valve operation signal of the one-shot circuit is sent to the operation valve 8.
[0018]
In the embodiment, the selected size and the spraying time are set in the CPU. However, the selected size may be set in the measuring instrument, and the spray timing and the spraying time may be set in the one-shot circuit.
[0019]
In addition, compressed air is used for the spray mechanism A, but it is also possible to directly pressurize the spray liquid W. In this case, for example, an operating valve such as a spraying liquid discharge valve of the pressurizing device is connected to a one-shot circuit. Further, depending on the properties of the spray liquid, the spray liquid may be heated so that the spray is easy.
[0020]
Operation of the embodiment
In the case of spraying to the CPU the size to be sprayed, for example, all the eggs of 20 g or more, the weight value of 20 g or more and the spray time are input, and the air compressor is operated. When the scale weighs the eggs, a size detection signal is sent to the CPU.
[0021]
Upon receiving this size detection signal, the CPU controls the timing of spraying so as to spray all chicken eggs of 20 g or more, and sends the spray signal to the one-shot circuit. Upon receiving the spray signal, the one-shot circuit sends a valve operation signal to the operation valve 8, operates the operation valve 8 at a predetermined timing, and sprays the spray liquid W from the spray gun 2 onto the eggs for a predetermined time.
[0022]
【The invention's effect】
Compared to applying a freshness-retaining liquid to chicken eggs that do not necessarily need to be kept fresh as in the past, the freshness-retaining liquid or disinfectant is selectively sprayed according to the size of the eggs, so that the spray liquid is wasted. It can be used effectively without.
[0023]
Further, since the spray mechanism is used, spraying of the freshness maintaining liquid or the disinfecting liquid can be efficiently performed by applying the freshness maintaining liquid by the rotating brush.
