A container transporting chute 8011 that is configured to transport the (loading) container C and has an endless rotating body with claws driven at two transporting speeds. A pair of endless rotating bodies 8121 provided between the pair of container transport chutes 8011
Container forcible conveying device 801 with four claws 8122 attached
2. A pair of container regulating guides 8013 disposed above the pair of container conveying chutes 8011, a transmission 8014 (not shown) including an inverter, and the like. The endless rotating body 8121 is set in advance by the transmission 8014. It is configured to be able to shift to a speed. Reference numeral 8002 denotes an article supply conveyor configured to insert articles G in a direction substantially parallel to the front wall C1 of the container C conveyed by the container conveyance conveyor 8001;
This is an inclined belt conveyor arranged so that articles G discharged from the container 02 can be loaded by gravity in a direction substantially parallel to the front wall C1 of the container C. Reference numeral 8003 denotes a container carry-in conveyor formed of a belt conveyor, and 8004 denotes a container carry-out conveyor formed of a belt conveyor. Thus, the containers C which are unpacked in units of containers C by the article storage and unpacking device 7000 and are continuously moving downward by the stacking speed substantially equal to the moving speed of the containers C, are continuously supplied by the main line 7002. And the articles G are stored in a container C in an aligned state so as to be stacked.
After temporarily suspending the container C in which the container G is loaded and the next container C, the next container C is moved to a position where the article G can be loaded at a speed higher than the moving speed of the container C during the loading of the product. There is something.

That is, five pieces are taken out in each main stream line 7002 and placed on the article supply conveyor 8002 in the width direction at a substantially constant pitch, for example, 0.5 second pitch, for example, 300 mm in length. The article G having a thickness of 50 mm is moved by the article supply conveyor 8002 in the direction of the container C. On the other hand, the container C is successively supplied to the container transport chute 8011 by the container carry-in conveyor 8003, slides on the container transport chute 8011, and
012. Note that the container C is the container transport chute 8
When the container is transferred from 011 to the container forced transfer device 8012 (see FIG. 22A), the container forced transfer device 8012
Are driven at low speed.

As described later, the container C transferred to the container forcible conveying device 8012 is conveyed at a low speed in conjunction with the conveyance of the container C in which the articles G are being loaded, and then temporarily stopped, and then stopped. After being conveyed at a high speed, the article G is moved to a position where the article G is put in by repeating low-speed conveyance, pause, and high-speed conveyance again.

When the container C is moved to the article loading start position, the transport speed of the container forcible transport device 8012 switches from a high speed to a low speed, and the articles G continuously supplied by the article supply conveyor 8002 have a plurality of rows. The articles G are put into the containers C which are moving at a low speed at a low speed in such a way as to be stacked five by one, and the put articles G are stored in the containers C in an aligned state. Note that the transport speed of the container forcible transport device 8012 when the article G is loaded into the container C, that is, the moving speed of the container C is the stacking speed of the loaded article G, which is 5 in this embodiment.
0 mm / 0.5 seconds = equal to or slightly faster than 6 m / min, for example, 6 to 7 m / min. However,
When the fourth-stage article G is put into the container C, the container forcible conveying device 8012 is stopped. That is, the final article G
When the container C arrives at the position where the container C is inserted, the claw 8122 attached to the endless rotating body 8121 is detected by the detector disposed at the predetermined position, and the container forcible conveying device 8012 is detected.
, And waits until the final article G is completely charged (see FIG. 22B).

When the final article G is put into the container C, the container forcible conveying device 8012 is driven at a high speed, and the next article G continuously conveyed at substantially the same pitch by the article supply conveyor 8002 is After the container C is transported to a position (see FIG. 22 (c)) where the container C can be inserted slightly above the front wall C1 of the container C, the transport speed of the container forcible transport device 8012 switches from the high speed to the low speed. Thus, the articles G are sequentially put into the next container C. Note that the article supply is performed so that the first-stage article G to be put into the next container C is put into the next container C without hitting the rear wall of the previous container C and the front wall C1 of the next container C. The transfer speed and transfer pitch of the conveyor 8002 and the high-speed transfer speed of the container forced transfer device 8012 are set. FIG. 23 shows a container forced transfer device 801.
FIG. 4 is an explanatory diagram showing an example of a shift state of a transport speed of a container C.
When the final article G is loaded into the
Numeral 12 is instantaneously driven at a high speed from the stop state, and is immediately switched to a low speed.

The container C into which the article G has been inserted is released from the container forcible conveying device 8012, and the container conveying chute 80
11 (see FIG. 22D), and is sent to the next step via a container unloading conveyor 8004 (see FIG. 22E). When the container C is changed from the inclined state to the horizontal state, the twenty articles G stored in the container C are arranged in a standing state from a stacked state.

As described above, the article packing method of the present invention has been described together with the embodiment of the article packing apparatus suitable for carrying out the present invention. However, the article packing method of the present invention is not limited to these. For example, articles G of the same type are stored in a plurality of first tributary lines 7001A arranged side by side with respect to one main flow line 7002 and placed on a plurality of first tributary lines 7001A arranged side by side. The articles G of the same kind may be taken out to one main stream line 7002 substantially at the same time and the articles G may be packed.

The length dimension of the articles G may be different for each product type. In this case, the main line 7002 has a virtual space corresponding to the transport order and the size of the articles G, that is, the length of each article G. A virtual space obtained by adding a certain margin space, for example, 200 mm to the height dimension is continuously set, and when the predetermined virtual space reaches a position facing the articles G to be unpacked, the articles G are moved to the main line 7002. You just have to take it out.

It is not necessary to store ten articles G in the first branch line 7001A. For example, all articles G stored in the first box B may be stored in the first box B from the bottom. 1
, And all the articles G stored in the second box B are stored in the first tributary line 7001A of the second row from the bottom, and the same applies in the unit of one box thereafter. The article G may be stored in the first branch line 7001A.

When there are three or more first branch lines 7001A containing articles G of the same kind, the articles G of the same kind stored in at least two first branch lines 7001A are almost simultaneously. What is necessary is just to be able to take out to the main line 7002.

Further, the number of articles G to be put into the packing containers C is not limited to 20, and the number of articles G to be put into each packing container C may be different.

[0055]

As described above, the article packing method of the present invention takes out an article from a container in which a plurality of articles of the same type are stored, and stores the extracted articles of the same type in a plurality of articles. The same kind of articles can be taken out from a plurality of article storage sections at the same time, if necessary, so that multiple kinds of articles can be moved at a desired quantity at a time, even when only the same kind of articles are packed. Can be assorted.
