JPS61197315A - Control unit of conveyor for collecting and conveying eggs from henhouse - Google Patents

Abstract

PURPOSE:To improve the efficiency of automatic processing of eggs, according to a method wherein an abnormal load due to stagnated flow of eggs on an egg conveying conveyor is detected to stop an egg collecting conveyor, with regard to the egg conveying conveyor mounted between the egg collecting conveyor and the egg aligning/supplying unit of an automatic egg processing unit. CONSTITUTION:Abnormal load detecting units 6 are mounted to an egg conveying conveyor 5 installed between an egg collecting conveyor 4 transferring eggs toward an automatic egg processing unit from a henhouse and the egg aligning/supplying unit 3 of the automatic egg processing unit. An abnormal load due to stagnated flow of eggs on the egg conveying conveyor 5 is detected to stop the egg collecting conveyor 4. Consequently, the labor frequently observing the conveying condition of the eggs on the egg collecting conveyor 4 is not necessary. Further, an accident due to the delay of detecting the stagnation of the eggs can be prevented, and the number of the operators and the labor of the operator can be reduced, and the efficiency of the automatic processing of the eggs transferred from the henhouse can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention collects eggs from large-scale chicken houses, arranges the eggs, washes them,
This invention relates to an automatic control device for an egg collection conveyor for transferring eggs to an automatic egg processing device that includes processes such as weighing, sorting, inspection, and packaging.

[Conventional technology]

In order to mass produce eggs and reduce costs, chicken houses were enlarged and automatic egg collection systems were adopted, as seen in Japanese Utility Model Publication No. 51-17180 and Japanese Unexamined Patent Publication No. 54-123484. A processing plant equipped with automatic egg processing equipment was installed nearby, and the produced eggs were processed one by one.
The products are cleaned, inspected, weighed, sorted, packaged, and shipped. As shown schematically in FIG. 2, between the chicken house 1 and the egg alignment supply section 3 of the automatic egg processing device 2, there is an egg collection conveyor 4 and eggs sent from the egg collection conveyor 4. An egg feeding conveyor 5 for feeding the eggs to the aligned supply section 3 is provided in series, and the eggs continuously fed by the egg collecting conveyor 4 are once transferred to the egg feeding conveyor 5,
The feeding speed and quantity to the alignment supply section 3 are controlled.

[Problem that the invention seeks to solve]

However, the amount of eggs supplied from the chicken house to the automatic processing device is not constant, and the eggs themselves have a special shape. This results in a disorderly and irregular state, and the feeding of eggs to the aligned and supplying section 3 becomes unsmooth, resulting in frequent congestion. If this congestion zone is not resolved quickly, accidents will occur in which a large number of eggs are damaged, so frequent monitoring by workers is required, and if a congestion zone occurs, it is necessary to immediately stop the operation of the egg collection conveyor. Must be.

The present invention has been made with the object of improving the problems caused by the congestion of eggs on the egg conveyor described above.

[Means for solving problems]

The present invention provides an abnormal load detecting device for detecting the congestion or abnormal deviation of eggs on the egg conveyor as described above.
For example, it is detected by equipping a strain meter, and when the amount of deviation of all the eggs on the egg conveyor reaches a preset reference value or more, the drive motor of the egg collection conveyor is stopped, More preferably, a lamp or a buzzer is used to notify a worker of the occurrence of an abnormality.

[For production]

If the eggs that have been transferred one after another onto the egg conveyor by the egg collecting conveyor become unsmoothly transferred to the aligned supply section for some reason, the number of eggs on the egg conveyor increases, or the eggs are unevenly distributed. , an abnormality is detected by the strain meter, and a switch is activated to stop the egg collection conveyor, and the transfer of eggs from the egg collection conveyor to the egg delivery conveyor is stopped until the eggs on the egg delivery conveyor are normalized.

〔Example〕

FIG. 1 schematically shows an embodiment of the invention,
3 is an alignment supply unit in the automatic egg processing device described above; 4
5 indicates an egg collecting conveyor, and 5 indicates an egg feeding conveyor. The egg conveyor 5 according to the present invention is supported on strain gauges 6, which amplify and detect distortion caused by an increase in the number of eggs on the conveyor 5 and distortion caused by left and right deviation in the direction of movement.

The specific structure of the strain meter 6 is omitted, but one with a well-known structure can be used.The normal egg transfer state is set in advance as a standard value, and this standard value is set to a preset limit value or more. If the distortion value is exceeded, the drive motor 7 of the egg collection conveyor 4 can be stopped and the drive motor 7 can be restarted once the weight or offset of the egg delivery conveyor is restored to within a limit value.

〔Effect of the invention〕

As described above, the egg collection conveyor control device that can be applied to the present invention is as follows:
An abnormal load detection device, for example, a distortion 6, 6 in total, and the drive motor 7 of the egg collection conveyor 4 is stopped when an abnormality occurs in the measured value by the strain meter 6. If a situation occurs in which the eggs sequentially transferred onto the egg conveyor 5 are not smoothly transferred to the alignment supply section 3 due to some reason and the eggs are completely jammed or lopsidedly jammed on the egg conveyor 5, The strain gauge 6 can detect this and immediately stop the egg collection conveyor 4 automatically. Therefore, not only is it unnecessary to frequently monitor the moving status of eggs on the egg conveyor 4 as in the past, but it is also possible to prevent accidents due to delays in detecting congestion, reducing the number of workers, and reducing the number of workers. This greatly contributes to reducing the labor of workers and improving the efficiency of automatic processing of eggs transferred from chicken houses.
