Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for transferring chicken eggs to different height positions, and more particularly to a device that can transfer eggs without breaking them at the beginning and end of the transfer operation.

The need to transfer eggs from below to above arises in poultry farming using multi-cage chicken houses for the purpose of egg collection.

Conventionally, as shown in FIG. 1, this type of transfer device has an endless belt 3 stretched between an egg supply section 1 at a lower position and an egg discharge section 2 at an upper position. Toothed rods 4 are protruded at equal intervals in the transfer direction, and the endless belt 3 and the toothed rods 4 form an egg support section 5, and the endless belt 3 and the egg supply section 1 or the egg discharge section 2 are connected to each other. In order to connect the movement of the eggs between them, the ends are located close to the endless belt 3 and the belts of the egg supply section 1 and the egg discharge section 2, and the tooth rod 4 passes through the end close to the endless belt 3. There is one that is formed into a hawk shape and has 6 and 7 arranged thereon.

Thus, the eggs on the bridge 6 supplied from the egg supply section 1 are scooped up by the tooth rod 4, and the eggs on the bridge 6 are scooped up by the toothed rod 4, and
It is supported within and rises. This egg is pushed out onto the bridge 7 by the tooth rod 4 and is positioned on the egg discharge section 2.

However, when an egg on the bridge 6 is scooped up by the tooth rod 4, the egg that is scooped up at the tip of the tooth rod 4 may be lifted slightly upward and then fall. Otherwise, the egg support portion 5 may rise without supporting the egg.

This is because the eggs on the bridge 6 cannot be reliably separated, and in order to ensure the separation of the eggs on the bridge 6, it is necessary to arrange the eggs in a direction perpendicular to the arrangement direction of the eggs on the bridge 6. It is best to raise the tooth rod from below the egg. In this respect, in the conventional case, the tooth rods 4 are disposed in the same direction as the arrangement direction of the eggs and rise from below the eggs, so that separation cannot be ensured as described above.

Further, when pushing the egg onto the bridge 7, the egg may not easily slide, and the egg may be caught between the tooth rod 4 and the bridge 7 and damaged.

In addition, when the endless belt 3 is provided with tooth rods in a direction perpendicular to the direction in which the eggs are arranged on the bridge 6 as described above, the problem is how to take out the eggs while reducing the impact on the eggs. Become. That is, if the bridge 7 is provided in the position shown in the conventional example, the bridge 7 and the tooth rod collide with each other, and the bridge 7 is rolled out of the egg support part 5 with its tip close to the tooth rod. This is because if you catch the eggs as they come, the impact that will be applied to the eggs will be great and cause the eggs to break.

The present invention has been made in view of the above circumstances, and its purpose is to be able to reliably separate eggs, prevent egg breakage at the beginning and end of the egg transfer operation, and remove eggs. To provide a transfer device capable of transferring eggs to different height positions, the feature of which is that in the device for transferring eggs from an egg supply part to an egg discharge part at different height positions, a rise rising in the egg supply part is provided. A chain that is rotatably driven in a vertical plane and stretched endlessly with a lateral movement process that moves horizontally in an egg discharge section, and eggs that are placed at equal intervals in the direction of movement of the chain. horizontal bars attached horizontally to the chain to alternately form wide parts into which the eggs fall and narrow parts to prevent the eggs from falling; In order to absorb the egg and support the egg on the wide part, a support member whose base end is attached to the horizontal bar and extends below the wide part, and a support member that lifts the egg in the wide part from between the horizontal bars and supports the egg in the wide part. In order to transfer the egg to the discharge section, the egg is disposed in the horizontal movement stroke, has teeth protruding from its circumferential surface at the same pitch as the wide portion, and rotates in synchronization with the moving speed of the chain. It consists of a lifting sprocket.

Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

In FIG. 2, 10 is a chain.

11 is a shaft disposed at a lower position; 12 is a shaft disposed diagonally above the shaft 11;
Reference numeral 3 denotes a shaft located at approximately the same height as the shaft 12 and on the opposite side of the shaft 11. Each axis 11,1
2 and 13 are arranged parallel to each other and horizontally, and a sprocket 14 is provided at each end.
(only one is shown) is attached. Although not shown, one of the shafts is rotationally driven by a motor.

The chain 10 is stretched endlessly around the sprocket 14 and faces each other in a vertical plane (only one of them is shown). Thus, the chain 10 performs a diagonal ascending stroke between the shafts 11 and 12, a nearly horizontal lateral movement stroke between the shafts 12 and 13, and a descending stroke between the shafts 13 and 11. It has a process.

Reference numeral 15 denotes a bottom plate, which has approximately the same width as the interval between opposing chains 10, and is fixedly provided below the chains 10 in the upward stroke and the lateral movement stroke.

As shown in FIG. 3, a horizontal crosspiece 16 is rotatably installed horizontally between the opposing chains 10. As shown in FIG. That is, the upper horizontal bar 16a and the lower horizontal bar 16b
are constructed at small intervals to prevent the egg from falling into it to form a narrow part, and the upper horizontal bar 16c is constructed to form a wide part into which one egg can fall below the lower horizontal bar 16b. and in this order chain 10
A horizontal beam 16 is installed throughout. Thus, an egg storage section 17 is formed between the lower horizontal rail 16b and the upper horizontal rail 16c and above the bottom plate 15, and this egg storage section 17 moves together with the chain 10.

A comb 18 is a support member for the egg, and its base end is attached to the lower horizontal bar 16b, and its tip extends along the bottom plate 15 below the upper horizontal bar 16c. There are two combs 18 for one lower horizontal crosspiece,
They are provided with a gap smaller than the size of the egg, and are made of an elastic body covered with plastic or rubber to absorb the impact when the egg falls into the egg storage part 17. It is supported on the bottom plate 15 so that it does not touch and is transferred.

Further, 18a is a tooth rod for regulating the horizontal movement of the eggs, and is attached to the horizontal bar to which the comb 18 is attached.

Note that the number of horizontal bars installed between adjacent egg storage sections is not limited to two, but may be three or more, and the shape thereof does not necessarily have to be a round bar. Further, the number and shape of the combs 18 are not limited to those shown in the drawings, and for example, the lower horizontal bar 16b and the upper horizontal bar 1
A bag fixed at both ends between the bag and the bag 6c may also be used.

Further, the horizontal beam 16 has only one end connected to the chain 10.
The bottom plate 15 may be attached at the other end to have a U-shaped cross section, and be slid onto the U-shaped side wall.

Reference numeral 19 denotes a belt conveyor serving as an egg supply section, on which eggs are conveyed.

Reference numeral 20 denotes a bridge that transfers eggs between the belt conveyor 19 and an appropriate position on the upward stroke, one end of which is close to the belt conveyor 19, the other end of which is close to the horizontal bar 16, and which is directed toward the horizontal bar 16. It is arranged so that it slopes downward.

A sprocket 21 is used to take out eggs from the egg storage section 17, and is located between the opposing chains 10, attached to the shaft 13, and rotated together with the shaft 13.

This sprocket 21 is designed as shown in FIG. The pitch of the tooth portion 21a is the same as the pitch of the egg storage portion 17, the size of the tooth portion 21a is large enough to allow the egg storage portion 17 to be inserted, and the height of the tooth portion 21a is such that it slightly protrudes from the horizontal bar 16. It's the height you get. Further, the tooth portion 21a has the same number of grooves 21b (two grooves in the illustrated example) as the comb 18 in the rotational direction, and a relief portion for the comb 18 is formed.

22 is a bridge from which the eggs lifted by the sprocket 21 are discharged; one end is close to the rotating circle of the sprocket 21, and the other end is close to an egg discharge section (not shown) and extends downward toward the egg discharge section. It is arranged on a slope.

Alternatively, the eggs may be discharged by lifting the comb 18 with the sprocket 21 without forming the groove 21b in the sprocket 21.

Since the present invention is configured in this way, the bridge 2
For eggs located above 0, the egg storage section 17 is on the bridge 20.
When opened at a position opposite to , it falls into the storage section 17 .

The impact when the eggs fall is absorbed by the comb 18 and the eggs do not break.

Also, since the horizontal bar 16 moves in a direction perpendicular to the direction in which the eggs are arranged on the bridge 20, the eggs are placed on the horizontal bar 1.
6. You will not be lifted upward by climbing on top of the person,
Egg rupture in this area does not occur. In addition, one egg storage section does not store more than one egg, and the eggs do not come into contact with each other during transportation and are not damaged.

The eggs in the egg storage section 17 are placed on the comb 18 and are placed on the bottom plate 1.
5 and is transferred from the upward stroke to the lateral movement stroke without contacting 5.

At the end of the horizontal transfer stroke, the eggs in the egg storage section 17 are lifted above the horizontal crosspiece 16 by the sprocket 21, and as the sprocket 21 rotates, they are gently discharged onto the bridge 22.

In addition, in the above-mentioned Example, the case where the egg was transferred upward was explained, but the egg can also be transferred downward in the same manner.

That is, as shown in FIG.
is stretched so that it faces the egg supplying bridge 20 in the upward stroke, moves to the downward stroke at the upper sprocket 14, and moves to the horizontal movement stroke via the guide plate 23, and is provided at the end of the horizontal movement stroke. The bridge 2 is moved by the sprocket 21 for lifting the egg.
2.

In this manner, the present invention has the remarkable effect of preventing eggs from breaking when transferring eggs to different height positions.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
