Abstract

PURPOSE:To prevent the same egg from being counted twice by providing a control arm behind a count plate in an egg transporting direction. CONSTITUTION:The tip end 4a of the count plate 4 is bent into a hook shape, and is protrudent inside the transporting passage of the egg 10, and is lifted by the advancing egg 10 so as to be rotated around a shaft 3. Besides, the opposite side 4b of the count plate 4 constitutes an operating part to open and close a switch 6. The control arm 5 too is supported by the shaft 3 so as to be rotatable, and in addition, it is protrudent obliquely from the top into the transporting passage of the egg, and it allows the egg to move forward, but prevents it from moving backward. Thus, double count can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a counting device in an egg collection device.

[Conventional technology]

Eggs laid in chicken houses are washed, sorted, counted, packed in boxes, and transported to consumption areas.

Because counting devices must count large numbers of eggs, they are often done electrically.

For example, in the counting device 11 shown in FIG. to generate a pulse signal, input this signal to the counter 15 and count it,
It is designed to be recorded and displayed.

[Problem to be solved by the invention]

The counting device is often installed just before the boxing station, but the boxing station is often set up immediately before the boxing station to adjust the number of eggs.
will be stopped.

Conventional counting devices such as those described above do not take into account the above-mentioned starting and stopping, and therefore errors in counting are unavoidable. That is, when the conveyor belt stops and starts again, the belt will move in the opposite direction. Then, the egg that activated the switch once activates the switch again, and one egg is counted twice, that is, double counted.

The present invention aims to eliminate the drawbacks of the conventional devices as described above.

(Means and effects for solving !Iff) The present invention provides a control arm that is rotatably supported at the rear with respect to the non-axis feeding direction of the count plate and projects diagonally from above into the egg transport path. It is characterized by:

Since the control arm projects diagonally into the egg transportation path, double counting can be prevented by allowing the eggs to move forward but preventing them from moving backwards.

〔Example〕 Hereinafter, the present invention will be explained in detail based on FIG. 1.2.

Reference numeral 1 denotes a counting device according to the present invention, which is gate-shaped, and a conveyor belt 2 passes through the bottom thereof. The conveyor belt 2 moves from right to left in the direction of the arrow in FIG.
transport. Inside the counting device 1, a count plate 4 and a control arm 5 are each rotatably supported on a shaft 3.

The tip 4a of the count plate 4 is bent into a hook shape and protrudes into the transportation path for the eggs 10, and is lifted up by the advancing rabbit 10 and rotated around the shaft 3.

The rear part 4b of the counting plate 4 is formed as a counterweight and applies a suitable force to the eggs. Also, count plate 4
The opposite side 4b constitutes an operating section for opening and closing the switch 6.

The control arm 5 is also rotatably supported by the shaft 3 and projects obliquely from above into the egg transport path. The control arm 5 applies a brake to the eggs 10' to temporarily stop the continuously transported eggs to avoid confusion in counting. Even if the egg that has passed through the control arm 5 tries to move backward together with the belt 2, the tip of the control arm 5 contacts the egg and prevents it from moving backward.

A counter 7 is provided on the counting device 1, and a switch 6
The number of passing objects is counted, recorded, and displayed. An adjustment bolt 8 is provided on the upper plate of the counting device 1, and by adjusting the adjustment bolt 8, the lower end position of the count plate 3 can be set as desired, and defective products (extremely small eggs, soft eggs with soft egg shells, etc.) can be excluded. can be done (
Removal of defective products requires separate inspection equipment).

The egg 10' sent from the right side in FIG. 1 first contacts the control arm 5 and is braked. previous egg 1
When 0 passes the count plate 4, the next egg enters the count plate 4.

At that time, if the eggs are not in a row, there is a risk of errors in counting. Therefore, in the present invention, as shown in FIG.
A divider 9 is provided. The divider 9 has an elongated plate 9m supported on a gate-shaped support device similar to the counting device 1, and the plate 9a extends along the conveyor belt 2 to the counting device 1. The eggs are divided into two rows by the divider 9 and are not mixed until the counting is completed.

〔Effect of the invention〕

In the present invention, since the control arm is provided behind the counting plate in the egg transport direction, even if the eggs once counted by the counting plate try to retreat, the control arm prevents them from retreating, thereby preventing the same egg from being counted twice. be done.
