Abstract

PURPOSE: To quietly change the direction of eggs, and to increase the quantity of change of a space between the eggs in a transferring device for changing the direction of eggs, which are carried in multiple lines from a supplying conveyor and which are directed sideways, to the lengthways and for narrowing the space between the eggs and for putting the eggs into a bucket of a delivery conveyor. CONSTITUTION: A device is formed of a link mechanism, which inclines a cup 12, which received an egg, so as to put the egg into a bucket with the dead weight thereof and of which movement is restricted by a lateral long hole 26 and which is formed of a fitting frame 9, a driven shaft 13, a cam follower 16 and a crank arm 17, and a driving mechanism for the link mechanism, which has two eccentric sprockets. Since the direction of eggs is quietly changed by this driving mechanism and the quantity of change of a space between the eggs at the time of putting can be increased by the link mechanism, impact and load is not applied to the eggs.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a series of egg processing systems, in which, after receiving an egg conveyed from a supply conveyor with its major axis lying horizontally, the major axis is changed vertically and the mutual spacing is changed. The present invention relates to a device for narrowing and transferring to a delivery conveyor, which is connected to the next process.

[0002]

2. Description of the Related Art Eggs conveyed by a supply conveyor equipped with multiple rows (usually 6 rows) of egg storage seats have their major axes lying sideways, that is, the major axes are orthogonal to the conveying direction of the supply conveyor. It is horizontal. Therefore, in the next step, for example, the packaging step, the long axes of the eggs are put vertically into the container and the spaces between the eggs are narrowed according to the packaging container. Requires a device that narrows the mutual distance and transfers the eggs with the long axis of the eggs vertical.

As such a transfer device, Japanese Patent Publication No.
The "egg transfer mechanism" described in No. 3-8423 is disclosed. However, this "egg transfer mechanism" changes the orientation of the eggs relatively rapidly in the intermittent drive unit, and when the eggs are loaded into the delivery conveyor, the loading angle of the eggs is relatively gentle and There was an unreasonable attitude of the chicken egg. Furthermore, there was a limit to the amount of change that narrows the distance between eggs on the delivery conveyor while changing the direction from horizontal to vertical.

At present, a series of egg processing such as so-called posture alignment, egg inspection, weighing, sorting according to size, packing, etc. for supplying raw eggs, washing eggs, drying, aligning sharp edges of eggs in a certain direction is performed for 1 hour. It is performed at a high speed of 75,000 per unit,
In addition to the fact that eggs are extremely susceptible to damage, it is important that the eggs are not subjected to impact or load as much as possible during the treatment process. If egg rupture occurs, other chicken eggs and equipment will be contaminated.Therefore, it is necessary to stop the operation of the system to remove the egg rupture and clean the contaminated part of the equipment. Will be significantly reduced.

In the above-mentioned "egg transfer mechanism", an unnecessary impact is applied to the chicken egg due to a sudden change in the direction of the egg, the impossibility of the posture at the time of loading on the delivery conveyor, the limit of the change amount when narrowing the mutual interval, etc. Or load will be applied.

As a means for improving the drawbacks of the "egg transfer mechanism", there is an "egg transfer device in an automatic egg washing and sorting device" described in Japanese Patent Publication No. 6-43211. However, since this device also uses the rocking mechanism, it does not meet the demand for high-speed processing of the chicken egg, and it gives unnecessary vibration to the chicken egg due to the rocking.

[0007]

The problem to be solved by the present invention is to change the direction of the eggs from the supply conveyor to the delivery conveyor more slowly than before, and to transfer the eggs to the delivery conveyor. The reason is to increase the amount of change that narrows the distance between each other as well as to perform the inputs smoothly.

[0008]

Reference numeral 25 denotes a rail fixed to the frame 24, which is horizontally provided with a horizontally elongated hole 26 in the front-rear direction, and the cam follower 16 can roll in the horizontally elongated hole 26. Reference numeral 27 denotes a vertical hole provided in the rail 25 at predetermined intervals in the vertical direction and opening at the lower edge of the rail 25.
8 is pivoted on its upper end.

Here, the attachment frame 9, the driven shaft 13, and the cam follower 16 and the crank arm 17 that move along the laterally elongated hole 26 form a link mechanism of the transfer device 8.

The six transfer devices 8 are attached to the rail 25 in the above-described structure, and the pitch of the cups 12 is fed by the supply conveyor 1 in six rows.
Equal to the pitch of.

Next, the drive mechanism of the transfer device 8 will be described with reference to FIG. 28 is a drive eccentric sprocket,
It is attached to the clamp 29 so that its position can be adjusted, and
Rotate in the direction of the arrow in the figure. Reference numeral 31 is a driven eccentric sprocket mounted on the sprocket shaft 30. 3

Reference numeral 35 denotes a drive sprocket, which is fixed to the drive shaft 18 of each transfer device 8. 36 and 36 are pinch sprockets. A driven chain 37 is attached to the driven sprocket 34, the six drive sprockets 35, and the two pinch sprockets 36.

When the driving eccentric sprocket 28 is rotated, the driving chain 33 intermittently moves, and as a result, the driven chain 37 also intermittently moves. Therefore, the crank arm 17 to which each driving sprocket 35 is fixed is also The transfer device 8 rotates intermittently so as to be suitable for receiving and charging the chicken eggs E.

The purpose of providing the driven eccentric sprocket 31 is as follows. That is, in the state of FIG. 6, the drive chain 3 driven intermittently by the drive eccentric sprocket 28.
3 is in a stopped state, and at this time, the transfer device 8 is the egg E
Is ready to receive. When the drive eccentric sprocket 28 further rotates from the state shown in FIG. 6 and the main drive chain 33 starts moving, the driven eccentric sprocket 3 is driven by the main drive chain 33 at a place where the amount of eccentricity from the sprocket shaft 30 is large.
When 1 is rotated, the driven eccentric sprocket 31 starts to move slowly. As a result, the entire transfer device 8 starts to move slowly. On the contrary, since the egg E is transferred, the driven eccentric sprocket 31 is rotated earlier due to the slow movement.

[0022]

Operation of the Embodiment As shown in FIG. 7, the cup 12 of the transfer device 8 is horizontal, and the crank arm 17 immediately after the cup E receives the chicken egg E supplied from the supply conveyor 1. The angular displacement of (equal to the angular displacement of the drive shaft 18) is 0 degree. At this time, the egg E has its long axis lying horizontally and is held horizontally by the cup 12, so that the holding finger 20 does not hold the egg E.

When the crank arm 17 rotates in the direction of the arrow (counterclockwise) in the figure, the cam follower 16 causes the laterally elongated hole 26.
It moves in the direction of the arrow in the figure (the direction away from the drive shaft 18). Therefore, the cup 12 gradually inclines.

As shown in FIG. 8, when the crank arm 17 reaches a displacement of 90 degrees, the cam rotor 21 separates from the cam 14 rotating with the drive shaft 18, and the pressing spring 2 is pressed.
The pressing finger 20 moves to the drive shaft 18 side by 3, and presses the tilted egg E to hold it in the cup 12.
At this time, the bucket 4 into which the chicken egg E is loaded is close to the loading position.

When the crank arm 17 reaches a displacement of 150 degrees and immediately before the introduction of the egg E, the cam follower 16 approaches the drive shaft 18 side as shown in FIG. The egg E can be loaded into the bucket 4 that has just arrived.

When the crank arm 17 is displaced around 180 degrees, the egg E is introduced. The state is shown in FIG. At this time, the cam follower 16 further approaches the drive shaft 18 side, the cup 12 is greatly inclined, and the interval (pitch) between the eggs E when the cup 12 receives the cup 12 is narrowed to the interval (pitch) between the buckets 4. Further, the cam rotor 21 contacts the cam 14 and releases the pressing finger 20 from the egg E, and the egg E is loaded into the bucket 4 which has reached the loading position by its own weight. Further, by the rotation of the crank arm 17, the transfer device 8 returns to the position shown in FIG. 7, and the above operation is repeated.

In FIG. 11, the drive shaft 1 of the crank arm 17 is shown.
The relationship between the two angular displacements is shown with the vertical displacement of 8 and the horizontal displacement of the drive shaft (not shown) of the driving sprocket of the delivery conveyor 3. From this figure, it is known that the egg E is put into the bucket 4 more gently and comfortably than before.

[0028]

Since the drive mechanism of the transfer device is constructed by using two eccentric sprockets, the eggs can be transferred more slowly than before, and the eggs are not impacted during the transfer.

The link mechanism utilizing the horizontally elongated holes makes it possible to easily change the throwing angle when the chicken is thrown into the delivery conveyor in terms of design. Furthermore, the amount of change in the interval for narrowing the intervals between the eggs can be increased while the eggs in the horizontal direction are oriented vertically, and the eggs can be transferred more smoothly.
