DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for aligning the sharp and blunt ends of a chicken egg, which is necessary for automatically or semi-automatically performing continuous steps such as sorting and packaging of the chicken eggs, that is, to adjust the direction of the chicken eggs. It relates to a device for aligning.

[0002]

2. Description of the Related Art When a chicken is placed sideways on a flat surface and pressed, the sharp end draws a small circle and the blunt end draws a large circle.
It is well known to make a fan-like movement with the sharp end toward the center. Utilizing this property, when the eggs are placed on the two rollers and the rollers are rotated, the eggs move in the axial direction in which the sharp ends face.

[0003] One of the typical devices for aligning the direction of eggs by applying the property that the eggs move in the axial direction on the acute end side during rotation is a unique device on a long roller row having a uniform outer diameter. The plate-shaped guide members are arranged such that, during the passage of the eggs between the guide members, only the eggs in a direction different from the alignment direction hit the guide members and are inverted, so that all the eggs are aligned. As the guide row formed between the guide members, 6 rows, 12 rows, or the like is used depending on the processing capacity.

[0004] The second is a "device for aligning the pointed end of a chicken egg in a predetermined direction" described in Japanese Patent Publication No. 45-35214. In this apparatus, a plurality of stepped rollers (the number of processing rows, for example, six) in which the amount of movement is ensured, in which the eggs move in the axial direction on the side of the sharp end due to rotation. In the course of rotation, each of the chicken eggs approaches the end of the roller depending on the direction within the stepped roller. Thereafter, by the operation of the guide lowering device, it is guided to the next roller with the sharp end down. In the roller at the next stage, the eggs with the sharp ends turned over only in a certain direction, so that the directions of the eggs are aligned.

[0005] However, in the former device, it is necessary to widen the distance between the guide members on the way in order to invalidate the reversal action of the egg which has already been directed to the target at the entrance of the guide plate. For this reason, the total width of the device is increased, and there is a disadvantage that the device protrudes from other conveyors. In addition, the chicken egg must be largely moved in the width direction along the guide plate, turned over, and then narrowed and moved again to the width of the entrance, which limits the shortening of the apparatus length.

In the latter device, the direction from the first stage roller to the next stage roller is changed while moving by the guide lowering device. This height difference is caused by the height of the entrance of the automatic sorting and packaging machine. However, there is a disadvantage that the height of the apparatus is increased or the height of the apparatus thereafter is decreased.

Further, since each stepped roller contains the amount of movement of the eggs in the axial direction and the pitch is not reduced all the time, the transfer device (the six rollers are transported in six rows by a six-row roller). Device to transfer eggs from one row to a conveyor)
There is a disadvantage that the speed of the row conveyor or the like is increased by the amount of the movement.

[0008] Japanese Patent Publication No. 7-64417 discloses an "apparatus for receiving or transferring an article such as an egg, a vertical conveying and supplying apparatus". This device utilizes the fact that the center of gravity of the egg is shifted toward the sharp end, and when the egg is sandwiched between two plate-like guides and slides down, the sharp end points downward in the middle. ing. However, since it is necessary to increase the falling distance of the eggs, the height of the apparatus must be increased, and the eggs are liable to be damaged.

[0009]

The problem to be solved by the present invention is that after the eggs transported on the first-stage roller conveyor are discharged to one side of the transport path and released, the eggs are not directed to the target. By inverting only the eggs by the next roller conveyor, the device for aligning the eggs is formed as compact as possible and the eggs are not damaged.

[0010]

The features of the device for aligning the orientation of chicken eggs according to the present invention are as follows. It consists of a first-stage roller conveyor, a crossover, and a second-stage roller conveyor,
The first-stage roller conveyor has a first-stage forced rotation mechanism for rotating the roller group, and a guide member for discharging the sharp end of the egg transported through the first-stage passage formed opposite to one side of the first-stage passage. It has.

The crossover is provided at the center of the outlet of the first-stage passage between the first-stage roller conveyor and the next-stage roller conveyor.

The next-stage roller conveyor includes a partition plate opposing the next-stage passage and one of the eggs connected to one side of the transition and extending toward the center of the next-stage passage, and is discharged and moved along the transition portion. The chicken egg whose sharp end is directed to one side of the crossover is raised, the blunt end is turned down after the dull end is raised, and the blunt end is directed to one side of the crossover. So
And a reversal guide member whose blunt end is conveyed below .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a first-stage roller conveyor, in which a roller group 3 is driven in a direction of an arrow a which is a conveying direction by an endless chain 2 driven by a driving means (not shown). Reference numeral 4 denotes a guide member using a small-diameter rod or a plate.
In the meantime, 6 rows (or 12 rows)
The first-stage passage 5 is formed. Width W of first stage passage 5
Since the length of a large egg is 65 to 70 mm at most, about 75 mm is sufficient.

Reference numeral 6 denotes a first-stage forced rotation mechanism which is driven endlessly by, for example, a driving means (not shown) of a plastic chain. The third lens group is forcibly rotated. Since the eggs E are forcibly rotated by the rotation of the rollers 3, the eggs E transported with the axis between the rollers 3, that is, orthogonally to the transport direction a, are gradually sharpened. It is moved in the axial direction of the facing direction. As a result, as shown in FIG. 1, the sharp ends of the eggs E1 and E2 are slid in contact with the guide member 4 on the sharp end side and conveyed.
Alternatively, it is discharged from the first stage passage 5 in a state close to the guide member.

Reference numeral 7 denotes a bridge between the first-stage roller conveyor 1 and the next-stage roller conveyor 9 at the center of the exit of the first-stage passage 6 with three guide rods 8a, 8b, 8c parallel to the conveying direction a. Also, they are horizontally arranged at equal intervals. In order to receive the eggs E released and dropped from the first-stage roller conveyor 1, the transfer 7 is located at a position slightly lower than the height at which the first-stage roller conveyor 1 transports the eggs E, and in the embodiment, about 26
mm lower. The transition 7 can be formed by one plate instead of the three guide rods 8a, 8b, 8c.

As described above, the bridge 7 is provided at the center of the outlet of the first stage passage 5. Then, the eggs released from the first-stage passage 5 are released with the sharp end slidably in contact with the guide member 4 or close to the guide member 4. As a result, as shown in FIG. 1, the chicken egg E1 having the sharp end on the left side in the transport direction a.
The egg E2 having the sharp end protruding from the guide rod 8a and the sharp end protruding to the right in the transport direction a, protrudes from the guide rod 8c and moves onto the crossover 7, respectively.

Reference numeral 9 denotes a next-stage roller conveyor. The endless chain 10 driven by a driving means (not shown) causes the group of rollers 11 to synchronize with the first-stage roller conveyor 1 in the direction of arrow a. Being driven. The next-stage roller conveyor 9 is connected to a next-step conveyor (not shown).

Reference numeral 12 denotes a partition plate, and between the opposing partition plates 12, six rows (or 12 rows) of next-stage passages 13 of the same number as the first-stage passages 5 are formed on the next-stage roller conveyor 9. . In addition, the front end portion 12 of the partitioning plate 12 on the side of the first roller conveyor 1.
“a” bends toward the center of the next-stage passage 13 to prevent the eggs that have passed the crossover 7 from jumping out of the next-stage passage 13. The partition plate has a function of preventing the eggs from interfering with the eggs in the next next passage when the eggs are turned over.

Reference numeral 14 denotes a reversing guide member.
a, is gradually bent (or curved) toward the center of the next-stage passage 13 and extends, and is gradually inclined higher toward the downstream in the transport direction a, and is formed so as to be horizontal. I have.

Reference numeral 15 denotes a next-stage forced rotation mechanism, which is constructed in the same manner as the first-stage forced rotation mechanism 6;
The rollers 11 are rotated in an area excluding the upstream side and the downstream side of the roller.

Incidentally, the guide member 4, the transition 7, the partition plate 1
2. The reversing guide member 14 and the like are fixed to side frames (not shown) via respective support members.

With such a configuration, the egg E sent from the supply conveyor (not shown) to the first roller conveyor 1 has its sharp end moved to one side of the first passage 5 and is discharged from the first passage 5. , Transfer to crossing 7.

As described above, since the egg E1 has a sharp end protruding from the guide rod 8a, as shown in FIG. 1, the egg E1 having moved the migration 7 by inertia at the time of release supports the blunt end. In addition, since the sharp end side rides on the reversing guide member 14, it stands with the blunt end down. Due to the inertia when standing, he falls further and turns around. The width near the upstream of the next-stage passage 13 needs to be large enough to allow the eggs to be inverted.
mm. In addition, the section A shown in FIG. 2 until the egg E1 that has passed through the crossover 7 turns over and turns over is the egg E1.
The roller 11 group is not rotated so as not to hinder the movement to change the direction.

The egg E2 protrudes from the guide rod 8c at the sharp end and moves onto the crossover 7, and due to the inertia at the time of release, the crossover 7
2, but without being obstructed by the reversing guide member 14, the blunt end is conveyed below it without changing its direction.

The egg E1, which has passed through the reversing guide member 14,
In E2, the axis is not orthogonal to the transport direction a by the rotation of the rollers 11 by the next-stage forced rotation mechanism 15, that is, if the attitude is disturbed, the axis is oriented so as to be orthogonal to the transport direction a. Transported to the next process conveyor.

[0026]

According to the present invention, the width of the first stage passage of the first stage roller conveyor is about 75 mm, the eggs can be shifted to one side of the first stage passage, and the eggs that need to be re-directed are turned over. The width of the next stage passage of the stage roller conveyor is also about 85 mm. Therefore, there is no inconvenience that only the present device protrudes from another conveyor row.

There is a disadvantage in that the roller conveyor row is divided into two stages, the first stage and the next stage, as compared with the conventional device in which the guide members are arranged on the roller conveyor to align the direction of the eggs. Since the width of the laconveyor can be reduced, the length of the apparatus can be shortened. In addition, it is only necessary to use the inertia at the time of discharge from the first roller conveyor and send it out to the next roller conveyor via a crossover, so that the head between the outlet of the first roller conveyor and the inlet of the next roller conveyor is used. Is small, the height of the entire apparatus can be reduced, and the shock applied to the eggs can be reduced.

Further, since the main parts can be constituted by the reversing guide member and some auxiliary guide parts, the structure is simple.
