DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket device for transporting eggs, which receives the eggs supplied by a supply conveyor and discharges the eggs to the next conveyor, and more particularly, to the transfer of eggs at the time of packing eggs at a poultry farm. It is used for egg transport in egg washing, drying and sorting factories.

[0002]

2. Description of the Related Art Egg transport bucket devices are mounted on a chain that rotates endlessly, and are intermittently ejected in plural units from a supply conveyor that accommodates and transports eggs in a multi-stage, multi-row egg seat. One egg in each cup, transported, and released to the next conveyor.

[0003] This type of conventional bucket device has a special shape that is supported by a pair of endless chains installed opposite to each other and moves only in one of the left and right directions.
For this reason, depending on the size of the workplace and the arrangement of other conveyor devices, the traveling direction is used on either the left or right side. There was an uneconomical problem of not being able to do so, and there was inconvenience in managing component parts.

[0004] In addition, the bucket device needs to be fixed in a state where a cup for containing eggs is opened and closed. Conventionally, when transporting while maintaining a normally closed state by a coil spring and pawl and discharging it to the next conveyor, a kick device equipped with a cup-shaped protruding part on the advancing path is used from the start of egg release at the time of starting egg release. The kick device had to be kept running until the player passed the lower end of the cup, which placed an excessive burden on the control of the kick device.

[0005] Accordingly, the configuration of the kick device becomes extremely complicated, and the number of parts increases.

[0006] Moreover, chicken eggs are extremely fragile,
Consideration must be given as much as possible so as not to impact
However , if the bucket device is supported at both ends as in the related art, the cushioning property is impaired, which is disadvantageous in protecting and transporting the eggs. The danger was great.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to simplify the structure of a conventional bucket device to reduce the number of parts, to realize easy control, and to improve cushioning. . Another object of the present invention is to make it possible to select the traveling direction of the bucket device on either the left or the right.

[0008]

[0019]

In the state where the cup 13 is open as shown in FIGS. 2, 7 and 8, it is assumed that the cup 13 advances in the direction of arrow a in FIG. Of course, it is the same even if it progresses in the opposite direction. Cup 1
The contact portion 7 of the driving sector gear 4 abuts on the start end of, for example, a block-shaped closer 33 provided on the traveling path 3. However, when the cup 13 moves in the opposite direction, the sector gear 5 becomes the main driving sector gear, and the secuda gear 4 becomes the driven sector gear.

Since the upper surface of the closer 33 is inclined upward in the traveling direction, as shown in FIG.
Rotates clockwise, the driven sector gear 5 meshing with the driven sector gear 4 rotates counterclockwise synchronously, and the cup 13 closes. When the cup 13 is closed, the interval between the spring columns 9 is widened, and the center of the coil spring 10 moves downward.

Since the latch 20 is provided with the spring guide groove 21 inclined upward to the chain 31 side, the coil spring 1
0, the latch 20 is moved to the rear side, that is, the chain 3
A pushing force is generated to one side.

When the contact portion 7 of the driving sector gear 4 reaches the end of the closer 33, the latch 20 is pushed by the coil spring 10 and falls down toward the chain 31, and as shown in FIG. The stopper portion 6 is the locking groove 2 of the latch 20.
2 and the cup 13 is fixed in a closed state.
The coil spring 10 is located at the lower end of the spring guide groove 21.

When the cup 13 is moved to the transporting end of the supply conveyor (not shown) in the closed state, the eggs E released from the supply conveyor are stored in the cup 13 as shown in FIG.

When the egg E is transported to the feed point to the next conveyor, as shown in FIG. 10, when the kick member 34 using a solenoid or the like kicks the head of the latch 20 to the opposite side of the chain 31, the stopper The part 6 is momentarily disengaged from the locking groove 22. Since the interval between the spring posts 9 is reduced by the coil spring 10, the center of the coil spring 10 is
1 to instantaneously fix the latch 20 as shown in FIGS. During this time, the interval between the spring supports 9 is reduced, so that the driving sector gear 4 rotates counterclockwise and the passive sector gear 5 rotates clockwise, and the cup 13 opens.

[0025]

[Effect of the Invention] Since the bucket device can be moved in both directions, it can be adapted to the condition of the egg processing equipment and only one type is required, which is economical.

When the latch is kicked, the bucket opens instantly, so there is no need to control the bucket until the egg is completely released. Further, since the spring for controlling the operation of the latch and the spring for opening the bucket are shared, the structure is reduced. It is simple and the number of parts can be reduced.

Further, since the bucket device is supported by a single conveyor chain, that is, cantilever, the cushioning property when the eggs are stored in the cup is enhanced, and the eggs are less damaged.
