Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously transferring and collecting eggs laid by the chickens in each cage in a large-scale poultry farming apparatus and transferring them at a stepped portion.

[0002]

2. Description of the Related Art Conventionally, in large-scale poultry farming equipment, eggs laid in a large number of rows of cages are collected in one place, washed and sorted, and then boxed and shipped. Is being done. In these working steps, eggs are often transferred continuously, but when they are transferred to places with steps having different heights, it is not possible to transfer them with a large inclination only by a belt conveyor. Therefore, a device for moving the stepped portion in the vertical direction is used. An apparatus for vertically moving such a stepped place is, for example, placing an egg received from the supply side on a U-shaped egg holding member, lifting it by a chain drive or the like, and reversing the egg holding member at the top. The structure is such that it descends to and passes to the discharge part on the opposite side of the appropriate height.

In such an apparatus, when the egg holding member is turned over at the uppermost portion, there is a problem that the placed eggs are rolled and collide with each other and are easily broken.
Therefore, as shown in FIG. 7, a transfer mechanism has been proposed in which the egg holding member is a uniaxially supported suspension swing type. This has one transfer chain, and the egg holding member is swingably supported by one shaft. The egg holding member on which the eggs received from the supply section is placed rises along with the transfer chain, and when the transfer chain is turned down by the uppermost sprocket wheel, by swinging in a suspended state like a swing, It starts descending with the eggs on it.

When it descends to reach the discharging part, the comb-shaped pushing mechanism pushes out the egg from the egg transfer device.

[0005]

However, the conventional rocking type transfer mechanism is uniaxially supported, so that it is swaying and unstable, and there is a problem that the eggs are easily hit and broken when shaken. In particular, there was a high risk of rocking and breaking when the egg was pushed out by the pushing mechanism.

[0006] Therefore, an object of the present invention is to provide a transfer mechanism capable of transferring an egg on a stepped portion without rolling while stably mounting the egg.

[0007]

According to the present invention, in an egg transfer device for transporting eggs, which are sequentially placed on an egg holding member from a supply section, in an up-down direction or an oblique direction and delivering them to a discharge section having different heights, a rotary shaft is provided. Are horizontally and diagonally displaced two active side wheels, and these driven side wheels are vertically and obliquely separated from each other by two driven side wheels that are respectively placed synchronously. Two series of transfer means consisting of two belts or chains driven vertically or diagonally were provided on both left and right sides, and were displaced with respect to the two series of transfer means in the same manner as the displacement of the rotary shaft. The two rotatable support shafts provided at the positions are provided on both the left and right sides, and the four holding shafts on the left and right sides support the egg holding member.

[0008]

According to the present invention, the eggs received from the supply unit are placed on the egg holding member. This egg holding member is supported substantially horizontally by two rotatable support shafts with respect to the two-system transfer means composed of two belts or chains. Since the rotary shafts of the two active wheels are displaced in the horizontal direction or the diagonal direction, when the two systems of transfer means hung on these active wheels are driven up and down, the egg holding member is It moves up and down while being supported almost horizontally.

Therefore, since the egg holding member is kept in the horizontal state even when the egg holding member is changed from the ascending to the descending along the wheel, the eggs do not collide with each other. Then, when the egg holding member on which the eggs are placed moves down to the discharging section, the eggs are pushed out to the discharging section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An egg transfer device according to the present invention will be described below in detail with reference to the drawings showing its embodiments.

Reference numeral 1 is a supply unit, 2 is an egg transfer device, and 3 is a discharge unit. The conveyed egg A is supplied to the egg transfer device 2 via the supply unit 1 and transferred to the discharge unit 3. At this time, the height of the supply unit 1 and the height of the discharge unit 3 are different.

The supply unit 1 will be described in more detail. The egg A placed on the conveyor belt 11 of the supply unit 1 is replaced on the second conveyor belt 13 along the guide 12. Since a gap lower than the normal egg height is formed between the conveyor belt 11 and the guide 12, an abnormal egg such as a soft-shelled egg does not work with the guide 12. Since it passes through the above-mentioned gap, it does not rest on the second conveyor belt 13.

In the vicinity of the end of the second conveyor belt 13, a comb-shaped egg receiver 27 whose tip is bent upward is fixed to the frame of the egg transfer device 2. The egg A conveyed by the second conveyor belt 13 is placed on the egg receiver 27.

The egg transfer device 2 will be described in detail below.
First, vertical frames are erected on both left and right sides of the egg transfer device 2. On the left vertical frame of the egg transfer device 2, a first active side wheel 21A and a second active side wheel 21B whose rotational axes are displaced in the horizontal direction, and these active side wheels 21
A first driven wheel 22A disposed below A and 21B
And a second driven wheel 22B and the active wheel 21A.
And the first chain hung on the driven side wheel 22A
23A, the active side wheel 21B and the driven side wheel 22
A second chain 23B hung on B and a motor 24 for synchronously rotating the first and second active wheels 21A, 21B.

Similarly, the right vertical frame also includes an active side wheel that is coaxially driven with the active side wheels 21A and 21B and a driven side wheel that is coaxial with the driven side wheels 22A and 22B. A third chain is provided on the active side wheel and the driven side wheel, and a fourth chain is provided on the active side wheel and the driven side wheel.

Reference numeral 4 denotes an egg holding member. As shown in FIG. 3, the left end of the egg holding member 4 is rotatable by support shafts 4A and 4B into first and second chains 23A and 23B, respectively. Supported by. Similarly, the right end of the egg holding member 4 is also rotatably supported by the third and fourth chains.
On the long member 41 arranged from the left end to the right end of the egg holding member 4, holding bodies 42 are arranged in a comb shape.

The part that receives eggs from the supply part 1 will be described below. Due to this structure, when the four active wheels on the left and right sides are driven to rotate,
Since the chain of 4 moves, the egg holding member 4 is driven to rise in the vicinity of the supply unit 1. Therefore, as shown in FIG. 4, the egg holding member 4 driven to move upward
Picks up the egg A placed on the egg receiver 27 from below and raises it. At this time, both the holder 42 of the egg holding member 4 and the egg receiver 27 are formed in a comb shape with the same pitch, but they are arranged so as to be displaced in the horizontal direction so as not to contact each other.

The following is a description of how the egg holding member 4 on which the egg A is placed in the egg transfer device 2 moves up and down. At the folded-back portion on the upper side of each chain, that is, the portion of the active side wheels 21A and 21B, as shown in FIG. 5, the egg holding member 4 rolls from ascending to descending with an egg placed thereon. At this time, the support shafts 4A and 4B at the left end of the egg holding member 4 are respectively attached to the first and second chains 23A and 23A.
Since it is rotatably supported by 23B, and the right end is also rotatably supported by the third and fourth chains and is synchronously turned from upward to downward, the direction does not change. Therefore, the eggs do not roll, and there is no danger of being damaged.

The following is a description of how the egg A placed on the egg holding member 4 and moved down is placed on the table 31 of the discharging section 3. As shown in FIG. 6, on the side of the discharging section 3 of the egg transfer device 2, comb-shaped pushing members 5 having the same intervals as the holders 42 of the egg holding members 4 alternate with the holders 42. It is arranged as follows. The push-out member 5 is rotatably supported by the vertical frames on the left and right sides and is biased by a spring 51 in the direction of arrow b.

Therefore, as shown in FIG. 6A, the pushing member 5 stops until the egg holding member 4 comes into contact with the stopper 52.
Is in contact with.

Then, as shown in FIG. 6B, when the egg holding member 4 descends, the pushing member 5 is pushed down by the elongated member 41 of the egg holding member 4 and resists the biasing force of the spring. Rotate clockwise. Next, as shown in FIG. 6C, when the egg holding member 4 is further lowered and the elongated member 41 is lower than the pushing member 5, the pushing member 5 is placed on the egg holding member 4. Egg A is pushed out slowly.

Then, as shown in FIG. 6D, when the egg holding member 4 is further lowered, the pushing member 5 completely pushes out the egg and slowly places it on the table 31. At this time, the pushing member 5 is in contact with the stopper. In this way, the eggs of the egg holding member 4 that are descending one after another are placed on the table 31 one after another.

According to the above-described egg transfer device, in the supply section 1, the nonstandard egg leaks from the guide 12 and is not supplied to the egg transfer device 2. Further, by providing a resin cover on the surface of the comb-shaped holding member 42 of the egg holding member 4 of the egg transfer device 2, it is possible to prevent the eggs from being damaged. Further, since the egg holding member 4 does not change the direction of the egg even when the egg holding member 4 changes from rising to falling, it is possible to prevent the egg from rolling and being damaged.

In the discharging section 3, the egg holding member 4
Since the egg A that has been riding on the egg is pushed out from behind and placed on the table of the discharge unit 3, there is almost no shock to the egg, and the effect of not easily damaging the egg is obtained.

Although the left and right four chains are moved in the vertical direction, they may be slanted. Further, although the upper wheel is driven, the lower wheel may be driven. Further, if the structure is such that slippage or other misalignment is prevented, it is possible to use a belt instead of the chain. Further, not only eggs but also various fragile articles such as glass products can be transferred.

[0026]

According to the present invention, when the eggs held in the egg holding member are transferred without rolling when they are transferred to the supplying section and the discharging section having different heights, the eggs may come into contact with each other. As a result, it is possible to prevent the eggs being transferred from being damaged or damaged. Further, since the egg holding member is supported at two places on each of the right and left sides, there is an effect that the eggs are not rocked during the transfer and the eggs can be transferred stably without contact between the eggs.
