Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a method for packing articles of a desired kind in a desired quantity, and more particularly to a method of packing only articles of the same kind. High-speed and almost no matter whether the goods are packed in different varieties, or the goods of some kinds are packed in plurals and the goods of other kinds are packed one by one. The present invention relates to a method for packing articles that can be packed with the same capacity.

(Prior Art) As a conventional technique relating to an article packing method, the technique described in Japanese Patent Publication No. 51-32035 is known.

To explain the conventional technology described in the above publication, Japanese Patent Publication No. 51-32035 discloses that a load is stored in a plurality of storage racks divided into vertically divided blocks at regular intervals, and the load is transported. One load for each block is sequentially placed on a transport conveyor provided in front of each stage of the storage rack so that loads do not overlap in the block, and then the transport is performed from the transport conveyor to the transport speed of the transport conveyor. A method of transporting cargo in a conveyor system in which a conveyor is transported onto a merging conveyor having a velocity in which the velocity components in the transport direction of the conveyor are made equal and the load is continuously unloaded by the merging conveyor is described.

(Problems to be solved by the invention) However, the above-mentioned conventional technology has the following problems.

That is, in the method of transporting cargo in a conveyor system described in Japanese Patent Publication No. 51-32035, a gate (stopper) is opened from each gravity conveyor (branch line) of a storage rack to convey a load (article) on a conveyor ( Main line), but different articles are stored in each branch line, so the ability to pack only the same type of articles is limited to the main line. It is limited by the ability to take out to the line and cannot be packed at high speed.

Therefore, an object of the present invention is to place articles of the same type on a plurality of branch lines, and to carry out the articles of the same type from a plurality of branch lines almost simultaneously as necessary,
It is an object of the present invention to provide an article packing method that can be packed at high speed.

In the above-described method of transporting goods in the conveyor system, the articles are merged at a constant interval regardless of the size of the articles to be unpacked, that is, at intervals of the vertically-divided blocks. The merging is performed with the space before and after the space, and the ability to arrange the articles is further reduced.

Therefore, an object of the present invention is to reduce the packing interval of articles after unloading as much as possible by unloading the articles to a virtual space corresponding to the size of the articles, and to reload the articles at a higher speed. It is to provide a packing method.

(Means for Solving the Problems) The configuration of the present invention that has solved the problems is as follows: 1) Articles of a plurality of types placed on branch lines for each type are packed in a desired number in a plurality of main lines, and a load is determined. In the method of arranging articles to be accommodated in an alignment container, a plurality of tributary lines are merged into one main flow line to form a tributary main flow transport line, and a plurality of sets of the tributary main flow transport lines are provided. The main stream line is extended to the packing container without merging with each other, and at least one kind of article is dispersedly placed on the branch lines of a plurality of different branch main stream transport lines, and is distributed and loaded on the plurality of branch lines. The same type of goods placed are unloaded from multiple tributary lines to different main lines at substantially the same time, and the same type of goods delivered almost simultaneously to each main line are unloaded without merging. 2) An article packing method characterized in that the articles are transported in parallel to each other, stored in the same packing container, and packed in the same packing container. Article packing method according to 1), wherein articles of the same type are placed on the branch line. 3) Articles are appropriately stored in the main line according to the article packing order and the size of the articles. A virtual space as much as possible is set in advance, and when the virtual space of the main line reaches the position of the tributary line on which the target article of the setting is placed, the article is carried out from the tributary line to the main line. The method of packing articles according to 1) or 2) above; 4) the virtual space is a virtual space on a mainstream line having a width obtained by adding a certain margin to the length of the article;
Item 3) The method for packing articles according to the item 3).

(Operation) In the article packing method of the present invention, a plurality of tributary mainstream transport lines are formed, articles of the same type are placed on a plurality of tributary lines of different tributary mainstream lines, and the same type of The articles are unloaded at a high speed by unloading the articles from the plurality of branch lines substantially simultaneously.

In particular, by carrying out an article to a virtual space corresponding to the size of the article, the packing interval of the articles after carrying out is reduced as much as possible, and the articles are packed at a higher speed. In particular, by setting a virtual space having a width obtained by adding a certain margin space to the length dimension of the article in the mainstream line, the cargo can be quickly and smoothly packed without a short interval.

Eight articles (G), for example, are arranged in the _first main stream line (2 ₁ ) from the bottom, and the length of the article (G) (dimension in the main stream line direction) is 300 mm plus a certain extra space of 200 mm. When there is a command to load the goods into the virtual space, that is, at a pitch of 500 mm, the pulse encoder mounted on the line shaft generates one pulse for each 1 mm movement of the main line (2 ₁ ). By counting these pulses with a pulse counter (not shown), tributary lines (1a), (1b), ‥‥, (1z ₁ )
The article (G) is unloaded onto the main stream line (21) at a timing after the correction of the position so that the articles are packed in a predetermined pitch and order.

In other words, when the spacing between the tributary lines (1a ₁ ), (1b ₁ ), ‥‥, (1z ₁ ) arranged side by side along the _first main line (2 ₁ ) from the bottom is, for example, 400 mm The distance between the most upstream (26th) tributary line (1z ₁ ) and the tributary line (1a ₁ ) is 400 mm × (26-1) = 10000 mm, and the first main flow line from the bottom (2) Is placed on the branch line (1a ₁ ), that is, the article (Ga) that is to reach the return box (H) first is delayed by 10,000 pulses from the start of packing. it may be carried out of the line (1a _1). That is, the branch line (1
a ₁ ) or the position correction value of the article (Ga), and the article (Ga) is transferred from the tributary line (1a ₁ ) after 10,000 pulses from the start of packing.
An instruction to take out an article is given to an article take-out device provided at the end of the branch line (1a ₁ ) so as to take out to the main stream line (2 ₁ ). Since the article (Ga) to be reached first at the final end, ie, the return box (H), is conveyed at the head of the main stream line (2 ₁ ), the unloading timing based on the packing order is set to 0 pulse.

The goods (Gg) which should reach the final end of the main stream line (2 ₁ ) in the water of the goods (Ga) are discharged from the branch line (1 g ₁ ),
The goods are packed in the virtual space 500 mm upstream from the virtual space of the article (Ga) set on the main flow line (2 ₁ ). That is, the distance between the uppermost tributary line (1z ₁ ) and the seventh tributary line (1g ₁ ) is 400 mm × (26−7) = 7600 mm,
Position correction value of tributary line (1g ₁ ) or goods (Gg) is 760
0 pulses. In addition, the item (G
The transfer interval with a) is 500mm, so 500 to 7600 pulses

After the goods (Gg), the goods (Gr) that should reach the final end of the main stream line (2 ₁ ) are discharged from the branch line (1r ₁ ),
The goods are packed in the virtual space 1000 mm upstream from the virtual space of the article (Ga) set on the main flow line (2 ₁ ). That is, the distance between the uppermost tributary line (1z ₁ ) and the eighteenth tributary line (1r ₁ ) is 400 mm × (26−18) = 3200 mm,
Position correction value of tributary line (1r ₁ ) or article (Gr) is 320
0 pulses. In addition, the item (G
Since the transport interval with a) is 1000 mm, 100
0 pulses article provided at the distal end of the branch line after 4200 pulses obtained by adding (1r ₁₎ from the article (Gr) article to retrieve the mainstream line (21) was taken out instruction branch line (1r ₁₎ extraction device ( Given to 3).

Following the above-mentioned article (Gr), an article (Gr) of the same type reaches the final end of the main stream line (2 ₁ ), and the article (Gr) is also carried out of the branch stream line (1r), and the main stream line (2 ₁ ) It is packed in the virtual space 1500 mm upstream from the virtual space of the article (Ga) set above. That is, since the transport interval with the article (Ga) that reaches the final end first is 1500 mm, the tributary line (1r) after 4700 pulses obtained by adding 1500 pulses to 3200 pulses.
_An article take-out command is given to the article take-out device (3) provided at the tip of the branch line (1r ₁ ) so as to take out the article (Gr) from ₁ ) to the main stream line (2 ₁ ).

The goods (Ga) to be reached after the goods (Gr) to the final end of the main stream line (2 ₁ ) are discharged from the branch line (1a ₁ ),
From the virtual space of the article (Ga) that should reach the final end of the main line (2 ₁ ) first set on the main line (21)
It is packed in the virtual space on the upstream side by 2000mm. Conveyance interval between the side and the article (Ga) that reaches the final end first is 2000mm
Therefore, 12000 which added 2000 pulses to 10,000 pulses
After the pulse, an article take-out command is given to the article take-out device (3) provided at the tip of the tributary line (1a ₁ ) so as to take out the article (Ga) from the branch line (1a ₁ ) to the main stream line (2 ₁ ). .

The article (Ge) that should arrive at the final end of the main stream line (2 ₁ ) after the article (Ga) is discharged from the branch line (1e ₁ ),
The virtual space of the article to be reached in the final end of the mainstream line (2 ₁₎ set on by the first main stream line (2 ₁₎ (Ga)

Also, since the transport interval with the article (Ga) that reaches the final end first is 3500 mm, the article (Gs) is transferred from the tributary line (1s ₁ ) to the main stream (2s) after 6300 pulses obtained by adding 3500 pulses to 2800 pulses. _An article take-out command is given to an article take-out device (3) provided at the tip of the branch line (1s ₁ ) so as to take out the product at ₁ ).

Although the embodiment in which one or two returnable boxes (H) are packed is described above, it is needless to say that a large number of returnable boxes (H) can be successively and continuously loaded.

In addition, when the articles (G) are packed in the main line (22) of the second stage from the bottom to the main line (25) of the fifth stage from the bottom, the position correction value and the conveyance interval are similarly calculated. , At predetermined timings, the respective tributary lines (1), (1),
‥‥ is controlled so as to carry out the article (G) from the main line (2).

As mentioned above, although one embodiment of the article packing method of this invention was described, the article packing method of this invention is not limited to these. For example, a plurality of branch lines (1) arranged in parallel with one main line (2),
(1) An article (G) of the same type is placed on {}, and a plurality of tributary lines (1), (1)} in which articles (G) of the same type are juxtaposed, and almost one at a time. May be carried out to the mainstream line (2) and be packed.

In addition, the length dimension of the article (G) may be different for each product type. In this case, a virtual space according to the order in which articles are packed and the size of the article, that is, A virtual space obtained by adding a certain extra space, for example, 200 mm to the length of the object (G) is continuously set, and when the predetermined virtual space reaches a position facing the article (G) to be unpacked, the article (G ) Is preferably carried out to the main line (2).

Also, in consideration of slippage or the like generated when the article (G) is conveyed on the main line (2), the article (G) conveyed on the main line (2) instead of the movement of the main line (2). Register the actual movement including the slip of the part in advance,
The number of pulse counts may be determined based on the registered movement.

If there are three or more tributary lines (1) on which articles (G) of the same type are placed, the articles (G) of the same type placed on at least two tributary lines (1) are substantially removed. What is necessary is just to be carried out to the main line (2) at the same time and to be packed.

When packing the articles (G) in the return box (H) in a matrix, the articles (G) may be packed so that an empty space is formed in the center.

(Effect of the Invention) As described above, in the article packing method of the present invention, a plurality of sets of tributary main transport lines are formed, and articles of the same type are placed on a plurality of tributary main transport lines of different tributary main transport lines. And
If necessary, articles of the same type are unloaded almost simultaneously from a plurality of branch lines, so that articles can be sorted at high speed. In particular, when packing only the same kind of articles, or when packing only different kinds of articles,
Alternatively, in any case where a plurality of articles of a certain kind are packed and a plurality of articles of another kind are packed one by one, packing can be performed at high speed and with substantially the same capacity.

In addition, by carrying out the articles to the virtual space corresponding to the size of the articles, it is possible to shorten the packing interval of the articles after carrying out as much as possible, and to carry out the article packing at a higher speed.
