Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a device for identifying defective chicken eggs, and its purpose is to accurately identify defective eggs from a large number of chicken eggs being transported. The aim is to improve the quality of shipped eggs and the inspection efficiency of workers by inspecting and eliminating eggs.

(Prior Art) Normally, eggs collected from a production site are washed, dried, weighed, etc. while being conveyed in six rows on a conveyor.

In recent years, the speed of these devices has been accelerated, and in particular, egg checking operations are now dominated by visual inspection by workers and manual sampling, making it no longer possible to perform sufficient inspections. It is well known that this is a major obstacle in increasing the speed of devices.

Therefore, as an alternative to the manual operation of sampling by an operator, there is an egg translucent inspection device disclosed in Japanese Patent Laid-Open No. 37460 of 1980, which instructs the egg by fitting it into the eggshell of a chicken egg.

(Problems to be Solved by the Invention) The egg transmission inspection device disclosed in the above-mentioned Japanese Patent Application Laid-open No. 37460/1980 has an elongated indicating means provided on a conveyor, and a lower end of the indicating means is engaged with the egg shell. In this egg transmission inspection device, the upper end of the indicating means is rotatably and telescopically attached at a connecting part, but as the position of the egg to be engaged moves away from the connecting part of the indicating means. Therefore, when engaging the egg located directly below the connecting portion, there is a large difference in the length of the pointing means, making it difficult to restore the pointing means against expansion and contraction, making it difficult to give instructions. In addition, since there are many cracked eggs as defective eggs, there is a problem that the instruction means breaks the eggshell due to the problem.

In view of this, the present invention allows workers to perform only visual inspection of defective eggs and eliminate them in a subsequent process, and by installing a designated operation section within the device,
The idea is to free up workers' hands and allow them to concentrate on visual inspections, significantly improving work efficiency, and also to speed up the entire device. In other words, by freely moving eggs parallel to the transport surface within the egg-checking section provided on the upper plane of the transport surface of the transport conveyor, and by giving non-contact instructions above the defective eggs, In addition, we aim to shorten the time and eliminate cracking of eggs due to egg shell pressing, and also make it possible to provide a wide egg-checking section to eliminate the shrinking field of view for visual inspection of workers as eggs are transported at higher speeds. It is something to do.

(Means for Solving the Problems) Therefore, the present invention provides a method for identifying eggs within an egg-checking section provided on a conveyor that conveys eggs in a plurality of rows. and a first signal generated by indicating eggs within the egg-checking section based on orthogonal coordinates with x and y axes perpendicular to the axis, respectively; In an egg checking device that specifies the position of the egg in the egg checking section specified by the x-axis and y-axis values that specify the position of the egg when the signal is generated, and the speed signal of the conveyor, parallel to the conveyance surface of the conveyor,
a first shaft installed in the vicinity of the egg-checking section across the conveyor; and a first shaft slidably attached to one end of the first shaft, parallel to the conveyance surface of the conveyor, on the upper plane. a second shaft that is slidable at right angles to the first shaft, and an upper flat surface parallel to the conveying surface of the conveyor; an operating section that is slidable in the upper egg-checking section; and a first shaft provided on the first shaft that detects a moving distance of the second shaft from a predetermined base point of the first shaft. a distance detector for detecting a moving distance of the operating section from a predetermined base point of the second shaft;
and a second distance detector provided on the second shaft, by means for indicating the chicken egg,
The present invention provides an egg checking device that freely moves the egg checking section on the upper plane in parallel to the conveying surface of the conveyor and designates eggs to be identified in a non-contact manner.

(Example) To explain one example of the present invention using figures, the first example is as follows.
In the figure, 2 is a conveyor, and eggs 1
are conveyed while being rotated, and pass through an egg-checking section 3 provided on a conveyor 2. At this time, a lighting device 6 is provided below the conveyor 2 in the egg checking section 3, so that the eggs 1 can be seen through. Further, a transverse shaft B' that crosses the conveyor 2 is provided parallel to the row of eggs 1 conveyed on the conveyor 2 and parallel to the conveying surface of the conveyor 2. A transverse shaft B is similarly provided in parallel to the transverse shaft B' so as to surround the egg checking section 3. Then, parallel to the conveying direction of the conveyor 2, both ends are connected to a transverse shaft B,
A penetrating shaft A is provided at B'. Therefore, the shaft A crosses the egg-checking section 3 on the upper plane parallel to the conveying surface of the conveyor 2 with the transverse shaft B,
It can slide perpendicularly to B'. An operating section 7 is provided through the shaft A so as to be slidable on the shaft A. Therefore, the operating section 7 can slidably operate the egg checking section 3 on the upper plane parallel to the conveyance surface of the conveyor 2. The above-mentioned transverse shafts B, B' and shaft A use a known linear scale for length measurement, and the movement distance of shaft A and the movement distance of the operating section 7 are determined by reading the checkered stripes carved on the shaft. The transverse shaft is captured as a pulse signal by counting the
B' and the movement distance detectors 4 and 5 on shaft A. There is an operating device 8 at the tip of the operating section 7, and this operating device 8 is used to select the first egg 1 located at one end of the first row of eggs 1 that has been transported to the egg checking section 3. 1
The position of shaft A on transverse shaft B' when the command is given is taken as the starting point on the x-axis of the orthogonal coordinates, and similarly, the position of operating section 7 on shaft A at that time is taken as the starting point on the y-axis. Set as starting point. In other words, these starting points serve as reference points. As a result, the position of the chicken egg 1 within the egg checking section 3 is determined by the orthogonal coordinates x,
It can be understood as y. Furthermore, since the eggs 1 are being transported, they are constantly moving, and the movement of the row of eggs 1 corresponds to the pulse signal output from the speed detector 12 provided in the drive section of the transport conveyor 2. The row of chicken eggs 1 is specified by counting the number of pulses. Pulse signals from the travel distance detectors 4 and 5 of the transverse shaft B' and shaft A, pulse signals output from the speed detector 12, and detection signals from the detection signal pushbuttons 10 and 11 are input to a calculation device. Then, the position of the defective egg Z is calculated.

Now, when the eggs being transported pass through the egg checking section 3 , when the worker finds a defective egg Z and wants to specify the position of the defective egg Z, the worker moves the holder 9 of the operating section 7 When the defective egg Z is defective content a, press the detection signal push button 10.
(Press button 11 for defect content b).
In other words, the shaft A moves while sliding on the transverse shafts B and B', and the operating section 7 moves while sliding the shaft A. Therefore, the operating section 7 can freely move the egg checking section 3 above the transport surface of the transport conveyor 2. Move to. Therefore, the operating section 8 of the operating section 7 points to the defective egg Z above the defective egg Z without contact. At this time, a detection signal is generated.
At the same time, the moving distance detector 4 of the transverse shaft B' detects how many units the shaft A has slid from this reference point, using the starting point of the x-axis of the orthogonal coordinates provided on the transverse shaft B' as a reference point. The pulse signal of the movement amount for calculation is counted and captured as a count number, and the movement distance detector 5 of shaft A uses the starting point on the y-axis of the orthogonal coordinates provided on shaft A as a reference point. In order to calculate how many units the operating unit 7 has been slid on the shaft A from this reference point, the pulse signal of the amount of movement is counted and also captured as a count number. In addition, since the pulse signal output from the speed detector 12 is always input to the calculation device, the flock of chicken eggs transported on the conveyor 2 is processed by inputting the detection signal from the detection signal push button 10. , At this time, the flock of chicken eggs within the egg checking section 3 is specified, and x
The axis and the y-axis are specified, and the defective egg Z is identified by this. Since the transport conveyor 2 is constantly rotating, the identified defective eggs Z are also moved. Since the number of pulses of the pulse signal output from the speed detector 12 before reaching the ejection position is calculated from the position specified when the defective egg Z is identified as the defective egg Z, the defective egg Z While confirming the current position of the defective egg Z, the defective egg Z is removed after going outside the egg checking section 3. The method of removal may be performed by a separate removal device provided on the same conveyor, or a separate device for removal may be provided. Further, it is also possible to send a signal from the arithmetic unit to the weighing device and cause the grade sorting device to process the eggs as a group of defective eggs.

(Effects of the Invention) As explained above using the figures, the operator's hands are freed from the work of picking out defective eggs because the operation part is held within the device of the conveyor, and the operator can perform visual inspection. I can concentrate. As mentioned above, in order to freely move the egg pointing means over a wide range parallel to the conveyor surface, the first shaft is moved across the conveyor parallel to the conveyor surface. A second shaft that can be erected and slid at right angles to the first shaft is provided with one end attached to the first shaft parallel to the conveying surface, and an operating section is attached to the second shaft. did. This made it possible to move the upper surface of the egg transport surface parallel to this transport surface and to direct the eggs without contact. Furthermore, it was possible to shorten the time and eliminate the cracking of chicken eggs caused by pressing the eggshells.
In addition, in order to eliminate the problem that the field of view for visual inspection of workers is reduced as egg transport speeds up, we have created a wide egg checking section. With fewer oversights, we are now able to greatly contribute to improving the quality of shipped eggs.
