Next, the operation of the loading device 13 and the holding device 14 of the conveyor 12 will be explained in conjunction with the conveyance of the distribution conveyor 5.

In FIG. 1, the loading device 13 for the conveyor 12 is represented by a square on the outside with respect to the distribution conveyor 5, and the inside square is represented as a holding device 14. The fact that the eggs 3 are stored in the loading device W 13 or the holding device 1j14 is indicated by marking an X inside each square.

The loading device 13 of the conveyor 2 is positioned in front of the distribution conveyor 5 in an empty state, and the holding device 14 is also positioned in the rear in an empty state and conveyed in the direction indicated by the arrow.

First, the front position provided on the conveyance path of the distribution conveyor 5 is at position A, and the holding device 14 is moved as shown in FIGS.
The cup 25 is positioned forward by moving the cup 25 as shown in FIG. 3(a). This is to first accommodate the eggs 3 in this cup 25. Figure 3 - Cup 2 as shown in (a)
5 is positioned forward, and is transported to a first supply position B in front of the measuring device 4 provided at the discharge end of the first supply conveyor 1. At this first supply position B, the eggs 3 that have been sequentially transferred in an indented manner by the first supply conveyor 1 are kicked out by two impellers after being weighed and transferred to the accelerator 30 (second (see figure).

This accelerating device 30 accelerates the eggs 3 to the conveyance speed of the distribution conveyor 5, and puts the eggs 3 into the cup 25 with their axes vertical. This accelerator 30 is already a well-known technology, and a detailed description of the tank bottom will be omitted.

After the eggs 3 are transferred to the cup 25, the conveyor 12 holding the eggs 3 in the cup 25 reaches position C at the rear by the distribution conveyor 5 conveying in the direction of the arrow. At position C, the cup 25, while holding the egg 3, moves forward from FIG. move backwards from

The eggs 3 transferred by the second supply conveyor 2 are weighed in the same way, and then put into the packet cup 34 by the accelerator 30 at the second supply position (see Fig. 4).The packet conveyor 6 is indicated by the arrow d. The packet cup 34 containing eggs 3 is conveyed in the direction of arrow d along with the packet plate 32 fixed to the endless chain 31, and the zero-distribution conveyor 5 and packet conveyor 6 overlap in a vertical relationship. There is a transfer position E on the transfer path, and FIG. 5 illustrates the positional relationship between the carrier 12 and the packet cup 34 at the transfer position iE.

This receiver is placed in the transfer position iE with the carrier 12 and the packet cup 3.
4 is being transported. This receiver is provided at the transfer position E in a shape in which the first guide rod 36 is gently descended along the conveyance path of the distribution conveyor 5 in the same direction as the arrow. Therefore, the finger arm 20 of the finger portion 16 is gradually pressed down by the first guide rod 36 and conveyed in the direction of the arrow. The transport body 12 and the packet cups 34 of the packet conveyor 6 are transported in the same direction at the same pitch, and the packet cups 34 are positioned directly below the transport body 12. That is, finger part 1
6 is gradually pressed downward, and the finger portion 18 of the finger portion 16 covers the egg 3 in the packet cup 34. After that, the finger lever 19 is pressed down by the second guide rod 37, and the finger part 18 linked to this is pressed down.
grabs egg 3 from both sides. After that, the third guide rod 38
As a result, the packet arm 33 gradually moves forward to tilt. Therefore, when the conveyor 12 leaves the transfer position E, the finger portions 18 of the finger portions 16 are conveying the eggs 3 while gripping them. That is, when this receiver passes the transfer position E, the loading device 13 of the carrier 12 is holding the egg 3, and another egg 3 is stored in the cup 25 of the holding bag W14.

The eggs 3 gripped by the input device 13 of the conveyor 12 are discharged according to grade according to the weight of the eggs 3 at a first packaging position F as a packaging station where the distribution conveyor 5 intersects with the packaging conveyor 7 in the upper row. The eggs are then put into egg packs 8 that are waiting on the packaging conveyor 7. The process in which the finger part 18 of the finger part 16 opens and releases the grasped egg 3 is described in Japanese Patent Application Laid-open No. 5
6-84218 and Japanese Patent Laid-Open No. 57-1.3024, and this embodiment also operates in the same manner. At this first packaging position F, all eggs 3 held by the feeding device 13 are released. Therefore, when the carrier 12 passes this first packaging position F, the feeding device 13 does not have any eggs 3, and the holding device 14 at the rear of the carrier 12 holds another egg 3. . A transfer position G is provided on the distribution conveyor 5 ahead of the first discharge position F.

At this transfer position G, the cup 25 of the holding device 14 holding the egg 3 is rotated approximately 180 degrees from the rear to the front (that is, the cup 25 of the holding device 14 holding the egg 3 is rotated approximately 180 degrees (i.e., from After the eggs 3 in the cup 25 of the holding device 14 are transferred to the feeding device 12, the cup 2 of the holding device 14 is now empty.
5 from the front to the rear (that is, move from Figure 3-(A) to (B) to Figure 3-(C)), and this transfer position is NG. The state in which the eggs 3 are transferred is shown in FIG. 6. Even in this transfer position G, the first guide rod 36 is in the shape of being gently descended in the same direction as the conveyance direction of the distribution conveyor 5. The finger arm 20 is attached to this first guide rod 36.
By being pressed downward, the finger part 16
tilts forward. Then, when the finger part 18 of the finger part 16 covers the egg 3 in the cup 25, one finger lever linked to the finger part 8 is gradually pressed down by the second guide rod 37, so that both sides Grab the egg 3 between the two. Finger portion 18 of finger portion 16
grabs the egg 3, the empty cup 25 of the holding device 13 moves rearward by the guide rail 28 (i.e., the cup 25 of the holding device 13, which has become empty as described above, Then, the feeding device 13 is again transferred to the next ejection station, the second ejection position I, with the egg 3 held in its grip. Also at the release position H, the eggs 3 held by the 2-feeding device 13 are released according to grade according to their weight, and are fed into the egg packs 8 waiting on the packaging conveyor 7.

Therefore, when passing this second release position H,
Both the feeding device 13 and the holding device 14 of the conveying body 12 are empty with no eggs 3, and as the distribution conveyor 5 conveys new eggs 3, the forward position is conveyed toward the position fiA. Ru.

In this way, when the transport body 12 is transported to position A with both the loading device 13 and the holding device (4) empty, the holding device 14 is first moved forward from the lower rear of the transport body (2). be positioned. After the holding device 14 holds the eggs 3 at the first supply position B, the rear positioning device 14 is then positioned again at position C, from the front to the lower rear of the carrier 12.

When the conveyor 12 is conveyed in the direction indicated by the arrow in this state, the receiving device 13 at the transfer position E grasps another egg 3 transferred by the packet conveyor 6.

Therefore, at this time, one egg 3 is held by the holding device 14 of the carrier 12, and another egg 3 is held by the feeding device 13.

On the way of the distribution conveyor 6, there is a first discharge position F.
At this first release position F, the egg 3, which is the other egg held by the feeding device 13, is released.

After passing this first discharge position F, there is a transfer position G, where the holding device 14 positioned at the bottom and rear of the carrier 12 moves forward.

Another egg 3 is held in the egg holding device 14, and the already empty feeding device 13 grips this other egg 3 again. When the feeding device 13 grips this other egg 3, the empty holding device 14 moves to the lower rear of the carrier 12 again. Then, at the second ejection position fiH, this feeding device 14 ejects another grasped egg 3.

This example is a case where it is adopted in an egg sorting and packaging device.
Needless to say, it's not limited to eggs.

Furthermore, although the present embodiment has been disclosed based on grasping means as the loading device and means having support as the holding device, the loading device may be a means having support as long as it has the role of discharging the article. Further, the holding device only has to have the role of holding the article during transportation, and may be a means for grasping the article.

(Effect of the invention) In order to increase processing capacity when distributing goods,
A method of transporting at high speed was used.

However, depending on the item being transported, there is a limit to the transport speed.
It was not possible to increase processing power. As mentioned above, by providing the article transport method of the present invention, the above-mentioned problems have been solved, and it has been possible to obtain the effect of doubling the throughput even if the article is transported at the same speed as before.

Furthermore, the method of transferring articles of the present invention changes the conventional way of thinking about distributing articles, and provides an apparatus having a new conveying form.
