Description

[Detailed Description of the Invention] In many cases, high-efficiency automatic machines are used to sort large quantities of eggs, raw chestnuts, etc., but this is especially useful for sorting perishables such as eggs, peaches, pears, etc. In some cases, due to safety considerations, the specimens are lined up one by one in a vertical line and transported using a transport device designed to prevent each individual from coming into contact with each other as much as possible. Generally, a method is adopted in which the waste is graded in sequence according to established sorting standards and discharged outside the line.

However, even with this method, in order to increase the processing capacity, the conveyance speed must be increased, resulting in safety issues when discharging outside the line, and a decrease in quality and freshness. It is well known that this was the cause.

For example, this kind of sorting work requires a transport speed of 10 to 3 m/s (1 m).
It is by no means uncommon for processing to be carried out at considerably higher speeds, and in the rows of large quantities of workpieces conveyed in this way, there are many different standards mixed together. However, there are some places where several pieces that should be rated to the same standard are lined up in a row, so naturally they are rated to the same standard and that number of pieces are continuously released outside the line. It turns out. Of course, there is a device to take the ejected material in another direction, but
When materials of the same standard are ejected in succession at high speeds as described above, it is unreasonable to rely solely on safety. If these objects to be processed come into contact with each other or collide with each other, the mutual impact will be large due to their speeds, and quality damage will inevitably occur.

In view of the above-mentioned circumstances, the present invention aims to prevent mutual contact and collision when discharging the materials to be treated according to their specifications, thereby increasing safety in terms of quality.

To explain the figure, 1 is a machine that holds the workpieces 2 vertically one by one.
A transport device that transports items in rows. 3.3 no, 4.4', 5
．． 5', 6.6/ are arranged at appropriate intervals along the conveying direction (arrow) of the conveying device 1, and preset A%B, C,
A discharge device configured to discharge the processed material 2 outside the column in accordance with the sorting standards for each stage of D, of which 3.4.5.6
are designed to emit the same standard as 3', 4', 5', and 6' located below each, so 'e3 and 3' are of A standard, 4 and 4/ are of B standard, and 5 and 5' is C standard, 6 and 6
1 performs D-standard emission. 3, 4, 5, and 6 located in the upper position control the release operation to 1 by the control device 7.
I'll do it on a daily basis. Reference numeral 8 denotes a transfer device which picks up the processed material 2 discharged outside the line in a different direction and transfers it to the next process (11), for example, a packaging process.

Now, when sorting work is performed in this way, among the 20 rows of a large number of objects to be processed transported by the transport device 1, there will naturally be some objects that should be graded to the same standard at each sorting stage in one row. A number of consecutive locations occur. If one group at one location is equivalent to A standard, the first one will be ejected out of the line by the ejection device 3 located above. However, since the ejection device 3 is controlled so that its ejection operation is performed one time at a time, the second one is ejected by the lower ejection device 3', and the third one is ejected by the -L hand ejection. This is the order in which they are emitted by the device 3. Therefore, there will be a positional lag in the transfer device 8''2 between the first and second discharges, and a time lag will occur between the first and third discharges, so contact and collision between them can be sufficiently avoided and the quality can be improved. Safety will be ensured. Of course, if something other than A standard, such as B standard, C standard, or D standard, is sent during that time, both of the emitting devices 3 and 3' will let it pass without being involved, and the subsequent It will be left to each stage of release.

As the control device 7 for causing the ejection operation of each of the upper ejection devices 3.4.5.6 described in 1-1 to be carried out one time at a time, as illustrated in FIG.
If you use a 1p-f 1op) circuit, you can expect extremely simple yet reliable operation.3. However, it is also possible to perform similar control without using an IC, for example, by using a stepping relay (relay with gears) to obtain a signal for each set number, or by using a timer to obtain a signal for each set number. It is also possible to take measures such as turning off the input signal within this time, or combining a cam device and a switch.

Since the present invention is as described above, fresh produce such as chicken eggs, peaches, pears, other bruised fruits, fruit vegetables, and root vegetables can be graded by weight, shape and size, or color tone. These ratings can be easily used in any case, and these ratings can also be applied to the later out-of-line discharge means. Blow-off chopstick method or nokuke,
Since Soto's tilting or open F dropping method can be used as is, it is widely possible to improve the safety of the quality of processed materials in this type of mechanical sorting (this has a remarkable effect).

Claims (1)

[Claims] The discharge devices that carry out continuous discharge by arranging the objects to be treated in a vertical line using a conveyance device are installed in pairs, each of which discharges the same standard, at the top and bottom (power moxibustion simulator) positions in the conveyance direction.
A method for sorting perishable perishables such as eggs, which is characterized in that the discharge operation is performed not continuously but once, for example, in one jump, by means of an appropriate control device.
