BACKGROUND OF THE INVENTION
The present invention relates to an apparatus capable of cleaning without removing a chicken egg transport holder in a chicken egg sorting and packaging system that is easily soiled by chicken manure, egg yolk, egg white, etc. leaked due to breakage of eggshell.
[0002]
[Prior art]
As shown in FIG. 1, for example, according to Japanese Patent No. 2758575, a versatile chicken egg sorting and packaging system includes an egg washer 31, a dryer 32, a direction aligner 33, an egg inspection conveyor 34, a sorter 39, and the like. Consists of. Eggs collected in the poultry house are supplied to the system at a speed of several tens of thousands per hour, conveyed from the egg washer 31 to the weighing unit 35 by a double row (usually 6 rows) roller conveyor, It is moved to the single row conveyance part 36 and is carried one by one with the egg conveyance holder. Eggs on the system are washed in the egg washing machine 31, removal of the washing water in the dryer 32, the direction of the sharp and blunt ends of the eggs in the direction aligning machine 33, dirt on the eggshell on the egg inspection conveyor 34, After sequentially passing through egg processing steps such as cracking and blood tests in eggs, rejected products are excluded upstream of the single-line transport unit 36, and the accepted products are packaged by weight downstream. On the other hand, various cleaning devices have been devised according to applications. For example, in Japanese Patent Application Laid-Open No. 11-028430, an automatic cleaning device that cleans the tableware transported by a belt conveyor or a rotary table by spraying a cleaning liquid from a fixed spray nozzle. Has been proposed. A sterilization apparatus (Japanese Patent Application Laid-Open No. 07-289158) for irradiating dirty eggs with ultraviolet rays, an apparatus for scraping off dirt adhered to the eggshell surface with a brush, and the like have also been proposed.
[0003]
[Problems to be solved by the invention]
The conventional egg sorting and packaging system (Japanese Patent No. 2758575) has first conveying means for conveying eggs in a row, weight discriminating means, and single row second conveying means orthogonal to the first conveying means. The egg holder attached to the second conveying means in the sorting and packaging apparatus is complicated in shape and has a large number in spite of the fact that chicken droppings, egg yolk, egg white, dust, germs, etc. are easily attached, and the holder in the vicinity. There is a complicated member for opening and closing, and it was difficult to prevent moisture from being scattered to the part, which could not be automated.
[0004]
In a cleaning apparatus using liquid cleaning agent and high-pressure air (Japanese Patent Laid-Open No. 11-28430), since cleaning is performed in one closed box, it is necessary to consider avoiding neighboring members against scattering of the cleaning agent. In addition, the gas-liquid mixed jet is a method in which a strong alkaline water cleaning liquid and air are mixed and then collided with an article to be cleaned, and cannot be applied to cleaning a holder of an egg sorting and packaging system having a precision rotation mechanism.
[0005]
Although the sterilizing apparatus using ultraviolet rays (Japanese Patent Laid-Open No. 07-289158) can be expected to sterilize only the surface, it cannot sterilize the inner layer of layered contaminants. Further, in the cleaning method of scraping off dirt with a brush, the shape of the egg holder is complicated, so that even the corners cannot be removed, and finally a cleaning process for the brush itself is added. Therefore, when dirt accumulates, the operator currently removes the egg carrier holder one unit at a time and cleans it or wipes it with a cloth, and no cleaning device using a cleaning agent has been proposed yet. Therefore, it is possible to clean the egg holder by hand, but in recent years, when the reduction of working hours and cost reduction is important, liquid can be prevented from adhering to the moving parts of the machine quickly and with little effort. However, there is a long-awaited need to provide a cleaning device that can maintain the hygiene of the egg holder.
[0006]
[Means for Solving the Problems]
The egg transport holder cleaning device for solving the above-mentioned problems is a first transport means for transporting eggs in a row, a weight discriminating means, and a second transport device for transporting eggs in a single line perpendicular to the first transport means. In an egg sorting / packaging system having a transporting means, an egg transporting / holding device cleaning apparatus for cleaning an egg holder that is continuously attached to the second transporting means while rotating the second transporting means without removing it. There,
An air discharge port that discharges high-speed air to the egg holder while avoiding the non-cleaning part, a cleaning agent discharge port that discharges the cleaning agent, and a control means that controls the discharging operation of the high-speed air and the cleaning agent The cleaning agent discharged from the cleaning agent discharge port is accelerated by the high-speed air and sprayed onto the egg holder to perform cleaning.
Normally, when the egg holder is liquid-washed, the washing water and the adhering egg yolk and egg white are mixed and permeate into the precision opening / closing part and solidify. Therefore, in the present invention, as shown in FIG. The egg holder of the means is held only from one side, and the directional high-speed air guided from the high-pressure air generator 6 prevents scattering of the cleaning agent to the holder opening / closing shaft 10 of FIG. The supplied liquid cleaning agent is accelerated with high-speed air and sprayed in the direction of the arrow 25 to continuously wash.
[0007]
According to the present invention, a predetermined control means can rotate the second transport means at a low speed at a specific position and continuously wash the egg holder attached thereto by automatic operation. do not do.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described. As shown in FIG. 2, the egg sorting and packaging having the first conveying means 2 for supplying the eggs 1 in a predetermined number of rows, the weight discriminating means 3, and the single second conveying means 4 orthogonal to the first conveying means 2. The cleaning apparatus of the present invention is attached to the system, and the egg holder 5 contaminated with egg yolk, egg white, chicken dung, etc. is continuously cleaned. First, the high pressure air generator 6 is used to guide the cleaning air diffusion box 8 from the compressed air path 7. The air outlet 9 is formed with a width of 2 to 3 mm so that the egg holder 5 moves in a straight line from the top to the bottom and is three times as long as the holder. 10. Mount the transfer chain 11 so that the high-speed air flows out in the direction of the arrow 25 in FIG. 3 while forming a shielded air flow so that the cleaning agent and the waste water after cleaning are not scattered.
[0009]
In order to supplement the cleaning effect of the high-speed air, the cleaning agent 12 is simultaneously injected from the cleaning agent discharge port 20 before the air discharge port 9 and accelerated by the high-speed air, and then collides with the egg holder 5. As a result, the side of the holder opening / closing shaft 10 which is desired to be shielded has a small amount of liquid and prevents splashing of water, and the side through which the egg holder 5 passes is closed to increase the amount of liquid, thereby improving the cleaning effect. . The waste water after washing is enclosed again by the partition plate 19 (FIG. 3) so as not to adhere to the holder opening / closing shaft 10, and is discharged downward.
[0010]
Downstream of the cleaning device, the waste water after the cleaning falls on the distribution conveyors 21 to 24 of the egg sorting and packaging system from the holder and branches to the egg holder 5 from the compressed air path 7 in order to prevent germs from breeding. The compressed air 13 is guided to the moisture diffusion air diffusion box 14 and discharged. The three water discharge ports 15 for removing moisture are formed and fixed in parallel with the moving direction of the second conveying means 4 and with a width of 2 to 3 mm and a downstream length of 60 mm.
[0011]
When the washing start button on the control panel 16 is pressed, the moving speed of the egg holder 5 is set to a low speed, and the second conveying means 4 is activated via the drive motor 17. Next, the high-pressure air generator 6 is started, and after a predetermined time, the electromagnetic valve 18 is opened to start injecting the cleaning agent. When the egg holder 5 is washed, the solenoid valve 18 is closed and controlled to stop after the draining operation.
【Example】
A detailed embodiment will be described by adding # 1 to # 9 for each step according to the control block diagram of FIG. After the daily packaging operation is completed in step # 1, the operator presses the cleaning start button attached to the control panel 16. In Step # 2, the egg holder 5 circulates while distributing eggs at a speed of 36 seconds per rotation during normal operation (processing capacity of 30000 pieces / hour). Therefore, the speed is set to a low speed of 1/6 (1 round 3:36 seconds) at which water removal can be sufficiently achieved, and the low speed operation is started via the drive motor 17 of the second transport means 4. In step # 3, the high-pressure air generator 6 is activated before the cleaning agent is injected to prevent the cleaning liquid from splashing on the holder opening / closing shaft 10, and the cleaning unit and the holder opening / closing shaft 10 are shielded. In step # 4, after the high-pressure air generator 6 using a fan having a large inertia weight is turned on, it waits for a constant speed. In step # 5, the solenoid valve 18 is opened, and the egg holder is directly placed in front of the air discharge port 9 from the four cleaning agent discharge ports 20 (FIGS. 2 and 3) in which the cleaning agent is linearly arranged in the vertical direction. Inject so that 5 does not collide. By this method, the cleaning agent is accelerated in the direction of the arrow 25 in FIG. 3 along the flow of high-pressure air to collide with the egg holder 5 and prevent entry into the holder opening / closing shaft 10. In step # 6, the egg yolk, egg white, etc. that have started to solidify cannot be sufficiently separated by only one washing step, so the washing effect is enhanced by setting the egg holder 5 to be washed four times (14 minutes 24 seconds). . In step # 7, the cleaning agent injection solenoid valve 18 is closed, the cleaning agent is not injected, and the cleaning air is held only, and the egg holder 5 is used for draining water. In step # 8, the water removing operation and the cleaning air installed downstream are used in combination, and the water is drained once. In step # 9, the high pressure air generator 6 is stopped, then the drive motor 17 is stopped, and the cleaning operation is automatically ended in 18 minutes.
