CONSTITUTION:In a condition (a) that link plates 4 and 6 are placed in a linear shape, an egg 3, mounted to a receiver plate 13, places the major axis being horizontally directed. And moving a guide rail 15 descending simultaneously with the movement of a chain 2 in the direction of an arrow head A, a roller 8 is depressed to the bottom. Here a roller 10, being placed on a rail 11, flexes the link plates 4 and 6 with an axis 5 serving as the center. Accordingly, a holding mechanism 12, mounted to an attachment 6b, moves while turning in a direction C with an axis 9 serving as the center. In this way, the egg 3 turns so that its major axis is vertically directed. By this constitution, the egg direction can be freely changed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an egg conveying device using a chain conveyor having a chain attachment.

(Prior art) Cheno, which is generally used for conveyors, etc., maintains its own pitch, and without changing this pitch, the chino itself is maintained in a straight line while being transported, and then placed on top of it. It was for transporting goods. Furthermore, even in chain conveyors having attachments, the attachments are for attaching members for conveying articles, and there are no attachments that allow the chain itself to bend or to shorten or return the pitch. In addition, Japanese Patent Publication No. 52-23943 discloses a roller conveyor in which the pitch of the rollers is changed by loosening the pitch of the rollers by rotating the screw, but this is only influenced by the pitch of the screw shaft. By the way, in an egg sorting and packaging machine, six eggs are normally conveyed on a supply conveyor with their long sleeves lying on their side. It was necessary to transfer the eggs with the long sleeves vertically to the single-row transport conveyor that transports the eggs in a single row adjacent to the discharge end of the supply conveyor. Since the single-row transport conveyor is a conventional chain conveyor, it is impossible to change the posture of the eggs during transport on this single-row transport conveyor. The egg that is being conveyed with the axis horizontally is picked up in that state, and the egg is rotated so that the long sleeve of the egg is vertical, and the machine is installed on the single-row conveyor that is conveying the egg below the discharge end of the supply conveyor. A transfer device was installed to transfer the egg receptacles into the ingredients.

(Problems to be Solved by the Invention) In addition to changing the posture of the long-sleeved chicken eggs from horizontal to vertical, the transfer device also accelerates the egg transfer to synchronize it with the single-row conveyor to be transferred. Because the process is carried out at the same time, the transfer device is complicated and has to be a mold device, and a slight timing difference can cause cracks and broken eggs.

For example, when eggs are transferred from a supply conveyor to a single-row conveyor with their long axes lying on their side, while the eggs are being conveyed on the single-row conveyor, the long sleeves of the eggs are turned sideways as they are being conveyed on a chain conveyor. It attempts to freely change its posture from a vertical position to a vertical position.

(Means for Solving the Problems) Therefore, the present invention provides a conveying device for individually holding and conveying chicken eggs, which includes a rail provided parallel to a chain conveyor having a chain attachment, and a link having the chain attachment. means supported by the rail provided on a connecting shaft on one side of the plate; a guide rail provided along the chain conveyor in contact with the chain attachment; and the chain attachment itself in contact with the guide rail or the chain. Holding of chicken eggs provided on the side of the link plate opposite to the attachment a! The holding mechanism rotates about the connecting shaft based on the shape of the guide rail of the chain conveyor, thereby controlling the axis of the eggs held by the holding mechanism. The purpose is to provide an egg conveying device that changes the

(Embodiment) A preferred embodiment of the present invention will be explained based on the drawings.The configuration will be explained in FIG. 1, which is a perspective view of the embodiment.
This figure shows an endless chain 2.
2' is provided, and one of the endless chains 2, 2' is provided with a holding mechanism 12 for holding the long sleeve of the chicken egg 3 horizontally below the conveying surface of the conveying device 1.

The endless chain 2, 2° is stacked on the end of the first link plate 4 with the first link plate 4 having no chain attachment sandwiching the first link plate 4 from the outside. It consists of a second link plate 6 which is pivotally attached to the shaft 5 of the link plate 6. Further, the first shaft 5
is coaxially attached to the similarly provided endless chain 2', so that the first link plate 4
The second link plate 6 is rotatable about the first shaft 5. Therefore, at the same time, the endless chain 2.2' bends rotatably about the first shaft 5. Further, the second link plate 6 of the endless chain 2, 2° has a chain attachment, and faces the link plate 6a without a chain attachment facing the outside of the conveying device 1, and has a shaft inside. The attached attachment 6b has a triangular shape with its apex positioned above the conveying surface of the conveying device 1, and a roller shaft 7 is attached to this apex in parallel to the first shaft 5. At the same time, it is coaxially attached to the apex of the other attachment 6°b similarly provided on the other endless chain conveyor 2, and the first roller 8 is attached to the roller shaft 7. Pivotally attached for free rotation. Similarly, a second
By connecting the shaft 9 to the other endless chain 2° as a coaxial shaft, the second link plate 6 and the first link plate are connected as in the case of the first shaft 5. 4 is rotatable about the second shaft 9, and therefore, at the same time, the endless chains 2, 2° are bent rotatably about the second shaft 9. A second roller 10 is supported by the second shaft 9 protruding from the second link plate 6.
Attach the shaft. Therefore, as the egg transport bag Wt1 is transported in the direction of arrow A, the second roller 10 rotates while coming into contact with the rails 11, 11, which are provided outside the transport path of the endless chain 2° and 2°. move while A triangular holding mechanism 12 is fixedly attached to the attachment 6b of the endless chain 2 below the conveying surface of the conveying device 1. The holding mechanism 12 has a tray 13 attached parallel to the rail 11. Therefore, the egg 3 held on the tray 13 is placed on this receiver with the long sleeve of the egg lying on its side. This receiver is held down from above by a claw bar 14 so as to sandwich the egg 3 placed on the plate 13, and this claw bar 14 is provided so as to rotate in the direction of arrow B and in the direction opposite to arrow B as required. . In other words, when taking the tray with the long axis of the egg 3 on its side, it rotates in the direction opposite to arrow B and opens, and the tray is placed in the tray 1.
3 and rotates in the direction of arrow B to sandwich the egg 3. Then, when the holding mechanism 12 rotates in the direction of arrow C to put in the egg 3, the long axis of the egg 3 becomes vertical, and if necessary, the claw bar 14 is rotated in the direction opposite to the direction of arrow B.
Drain 3 chicken eggs. Further, the upper part of the first roller 8 is in contact with the roller surface of the first roller 8,
A guide rail 1 that controls the conveyance path of the first roller 8
5 will be provided. As shown in FIG. 2, this guide rail 15 is connected to the egg transport bag r! ! , 1, there is a section provided above the conveying surface of the conveying device 1 and a section provided below the conveying surface, and the guide rails 15 of different heights have a gentle slope. They are connected by rails 15. Therefore, the first roller 8 that comes into contact with the lower surface of the guide rail 15 is pressed down and restored by the shape of the rail of the guide roller 15.

The first link plate 4 and the second link plate configured as described above.
The conveying device 1 is endlessly connected with the link plates 6 of the chain, and its movement will be explained based on the side view of the endless chain shown in FIG.

FIG. 2-(A) is a diagram in which the first link plate 4 and the second link plate 6 are conveyed while being held in a straight line without bending around the first shaft 5, and the first link plate 4 and the second link plate 6 are conveyed while being held in a straight line without bending around the first shaft 5. 8 to the guide rail 15, and the second roller 10 to the rail 1.
1 and is moving in the direction of arrow A. Therefore, the egg 3 placed on the receiving tray 13 is transported with the long sleeve of the egg lying on its side. Figure 2-(b) shows the guide rail 1
5 is a gentle downward slope with respect to the direction of arrow A, and the first roller 8 in contact with this guide rail 15 is pressed downward by the conveyance of the endless chain.

In addition, since the second roller 10 is moving in contact with the rail 11, it bends while pressing the first link plate 4 and the second link plate 6 downward about the first shaft 5. Therefore, the holding mechanism 12 attached to the attachment 6b of the second link plate 6 bent downward about the first shaft 5 moves while rotating in the direction of arrow C about the second shaft 9. Then, by the rotation of the holding mechanism 12, the egg 3 placed on the tray 13 is also moved so that the long sleeve of the egg gradually becomes vertical. The figure shows a state in which the first roller 8 in contact with the link plate 6 is pushed down further and the second link plate 6 stands vertically. That is, the state in which the second link plate 6 stands vertically is when it is pushed down the most, and from then on the guide rail 15 is parallel to the rail 11. At this time, the egg 3 placed on the tray 13 is kept in a state in which the long sleeve of the egg is vertical. In this way, by conveying the egg conveying device 1 in the direction of arrow A (A) → (B) → (C), the first link plate 4 and the second link plate 6 are linearly aligned. - From the state of moving parallel to the link plate 11, the first roller 8 approaching this section is pressed down by the guide rail 15 having a gentle downward slope, and the first link plate 4 and The second link plate 6 moves to a bent state around the first axis 5. and second link plate 6
is bent until it stands perpendicular to the rail 11,
After this, the guide rail 15 is arranged parallel to the rail 11 again, and moves while maintaining this state. Although not shown, by returning to the original height of the guide rail 15 by a gentle uphill slope, the state shown in FIG. 2-(a) is restored.

As mentioned above, the chain itself of the chain conveyor is bent due to the shape of the guide rail 15, and the holding mechanism 12 fixed to the attachment 6b of the second link plate 6 is bent.
movement is controlled. In other words, the egg 3 placed on the holding mechanism 12 is gradually turned vertically from a horizontal position with the long axis of the egg 3 centered on the second axis 9 due to the downward slope shape of the guide rail 15. Status! The second link plate 6 now stands perpendicular to the rail 11! When the chicken egg 3 is bent until it bends, the egg 3 moves with the long sleeve vertical, and although not shown, the egg 3 moves along the guide rail 15 (not shown).
By returning to the original height of the guide rail 15 by a gentle uphill slope, the long sleeve of the chicken egg 3 returns to the state where it lies sideways. That is, the holding mechanism 12 is connected to the guide rail 15.
rotates around the second axis 9 due to the shape of the
This rotation of the holding mechanism 12 changes the posture of the held egg.

FIG. 3 shows another embodiment in which a slide bin 16 is provided as a supporting means and a guide rail 17 having a U-shaped cross section is provided as a rail.

In another embodiment, a chain conveyor having an attachment reduces the pitch of eggs held on one side to a discharge location provided on the other side with respect to the sprocket by rotational operation of a sprocket. It may be a chain belt that reciprocates for discharge, and it does not necessarily have to be an endless chain. It may also be a chain conveyor with a single row of endless chains. In this case, in the above embodiment, the The guide rail 15 that comes into contact with the first roller 8 is connected to the first roller 8.
Conveyance can be realized by providing the slide pins 16 and guide rails 17 shown in FIG. 3 in place of the second roller 10. Similar effects can be obtained with the holding mechanisms provided in these other embodiments. Furthermore, it goes without saying that the egg conveying device of the present invention can be used not only for eggs but also for fruits and vegetables.

(Effects of the Invention) As described above, in the egg conveying device of the present invention, the guide rail in contact with the chain attachment and the supporting means provided on the connecting shaft on one side of the link plate having the chain attachment are in contact with each other. By using a chain conveyor that is controlled and conveyed by rails,
The long axis of the egg held in the holding mechanism of the transport device is freely changed from a horizontal state to a perpendicular state to the transport surface,
It was possible to change the orientation of eggs during transport. If a certain direction is required for the eggs to be transported, this can be achieved by configuring the shape of the guide rail corresponding to the required section. The conveying device having the holding mechanism of the present invention is not limited to the above-mentioned egg sorting and packaging device, and can be used for other conveying devices as well. You can also get the same effect.
