Abstract

PURPOSE:To arrange eggs in a small space in a proper order, by pushing the eggs to roll on rails with their major axes approximately perpendicular thereto and simplifying the structure of a device wherein the eggs are caused to drop off from an egg receiver extending from the unloading end of the rails with their sharp end downward due to the loss of the balance. CONSTITUTION:A plurality of eggs 8 being conveyed in a row on an egg feed conveyor 1 is transferred on rails 2 with the major axis of the egg 8 approximately perpendicular thereto. Each of pushers 31 provided on an egg carrying conveyor 3 rolls an individual egg 8 along the rails 2. The egg 8 is moved rotatably around its major axis to the unloading end of the rails 2 for reception by a receiver 4, from which the egg drops with the sharp end 81 downward losing its balance on account of the relation between its special shape and center of gravity. The eggs 8 are packed through a funnel-shape guide 5 into a container 6 with the sharp end 81 down successively in an orderly manner by a movable table.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is directed to placing chicken eggs in a packaging container with their sharp ends facing downward.
This relates to a method of arranging chicken eggs for tying.

(Prior Art) Conventionally, as a method of arranging eggs of this type, as described in Japanese Patent Application Laid-Open No. 52-32792, a separation action section, a reversal action section, and an alignment action section are provided in the running direction of a roller conveyor. The eggs supplied onto a roller conveyor are rolled and turned depending on the relationship between their unique shape and center of gravity, and the sharp ends of the eggs are aligned in a certain direction.
There is one that is transferred to another conveyor device and dropped with the sharp end facing downward.

(Issue g to be solved by the invention) However, in this conventional method, in order to reverse the eggs on the roller conveyor and change the orientation, the roller conveyor must be modified in many ways, resulting in a complicated device structure. They have the disadvantage that they tend to have the same number and require a large space. Furthermore, since the unique shape and center of gravity of the eggs are used to line them up on the roller conveyor, there is a drawback that the alignment of the eggs tends to be uncertain.

An object of the present invention is to provide a method for arranging chicken eggs that solves the conventional problems.

(Means for Solving the Problems) In order to solve the above problems, the method for arranging chicken eggs of the present invention involves placing chicken eggs on two rails provided in parallel with a predetermined interval, so that the long axis of the eggs is approximately perpendicular to the rails. Then, each egg is pushed and rolled in the above state to move it on the rail.
At the end of the rail, the egg is placed on a narrow holder that extends from the center between the rails in the direction of rail extension, and the egg is balanced on the holder so that the egg falls with the sharp end facing downward. .

(Function) According to the above method, the egg is rolled on the rail with its long axis as the axis of rotation, and at the end of the rail, the egg is once transferred onto the holder with its long axis almost perpendicular to the holder. Due to the special oval shape and location of the center of gravity, the egg loses its balance on the receiver and falls with its sharp end facing downward.

(Example) The present invention will be described below with reference to the drawings.

FIG. 1 shows an example of an apparatus using the alignment method of the present invention, (1
) is the egg supply conveyor, (2) is the rail, (3) is the chicken ψ transfer conveyor, (41 is the receiver, (5) is the funnel-shaped guide,
(6) is a packaging container, (7) is a moving table, and (8) is an egg.

The egg supply conveyor (1) is for supplying eggs (8) in rows onto the rail, and a bar conveyor for rows or the like is used. Eggs (8) are carried on the conveyor (1) so that their long diameters are substantially perpendicular to the direction of movement of the conveyor (1).

Two rails (2) are provided straight in parallel in the extending direction of the egg supply conveyor (1). Rail (2), (2)
The spacing between the chicken eggs (8) is made smaller than the short axis of the chicken eggs (8), and as in the third section, the chicken eggs (8) are played on the rails (2), λ) with their long diameters almost perpendicular to the rails (2), n). It is made to be moist. Further, although the rails (21, t21 are generally sloped upward in the direction of travel), they may be provided in a substantially horizontal direction.

The egg transfer conveyor (3) is provided with rails Ql and C21 in the upper direction, and a large number of pushers (31), (31),
9, the pusher (31) is the above-mentioned rail (support) as shown in Figures 2 to 4.
, and (2), and are designed to extend tMa along the opposing surfaces of the rails) and (2). Moreover, a space is provided between adjacent pushers (31), (31) to accommodate one chicken egg (8).

The receiver [41 is the rail (2) at the end of the rail (2)
), ■) extends straight from the center in the extending direction of the rails (2), (2). The receiver (4) has a narrow width as shown in FIGS. 2 to 4, and is long enough to hold one chicken egg (81). Thin plates and strips are used.

The funnel-shaped guide (5) is provided below the receiver (4), and has an elliptical tube at the top and gradually becomes a circular tube toward the bottom.

The packaging container (6) is a pack or tray in which the eggs (8) are lined up and packed, and is sequentially supplied below the funnel-shaped guide (5) by a supply device U (not shown), and packed with the eggs (8). It is designed so that it can be transported when it is carried.

The movable table (7) moves at predetermined intervals in two axial directions to strain the egg (8) so that it fits in a predetermined position in the packaging container (6).

Therefore, in the method of the present invention, first, the egg supply conveyor (1)
The chicken eggs (8), (8), . At this time, each egg (81 is transferred onto the rails (2), (2) with its long axis substantially perpendicular to the rail (2), (21). Next, each push tool (31) of the egg transfer conveyor 0 is transferred. ) by each chicken egg (8)
Push and roll it along the rails (2) and (2). Then, each egg (8) is rolled with the long axis as the rotation axis, and the rail (2)
)), a) is moved to the end of this rail C2), (
2) At the end, as shown in Figures 2 to 4, the egg (8) is rolled onto the receiver (4) in the above state.
The chicken egg (8) above loses its balance due to the relationship between its special oval shape and the position of its center of gravity, and as shown in Figure 4, the egg (8) loses its balance.
) falls downward. At this time, use the funnel-shaped guide (5
) to guide the egg (8) so that the sharp end (8) faces downward.The fallen egg (8) is packed into a packaging container (6) as shown in Figure 1, and then moved to the moving table (7). The eggs (8) are arranged and packed into the packaging container (6) by this operation.

(Effects of the Invention) As detailed above, in the arranging method of the present invention, the eggs are pushed and rolled on the rail with their long diameters substantially perpendicular to the rail, and the eggs are moved on the receiver extending to the end of the rail. Because the egg is dropped with the sharp end facing downward due to its balance, the structure of the device itself can be simplified and the orientation of the eggs can be aligned in a small space, and the egg can be reliably dropped with the sharp end facing down. This can be arranged.

Therefore, it can be suitably used for packaging eggs, such as packaging eggs in packs and trays.
