Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for inserting partition plates between articles, which inserts partition plates into a required number of grouped articles.

“Prior Art” Conventional devices for inserting partition plates between groups of articles usually
It is equipped with a grouping mechanism for grouping articles according to a required number, and a partition plate insertion mechanism for inserting a partition plate into the group of articles grouped by the grouping mechanism. There are known devices in which a partition plate is forcibly pushed into the container, and devices in which the gap between articles is forcibly increased and then the partition plate is inserted into the gap by its own weight.

However, in this type of conventional partition plate insertion device, the article is forcibly spread out by inserting the partition plate or by the partition plate insertion mechanism, so if the article is unstable, it may fall over when the partition plate is inserted. This tendency was particularly strong when driving at high speeds.

For this reason, a partition plate insertion device has conventionally been proposed in which the articles in the front and the articles in the rear of the group of articles are supported by a fall prevention member to prevent the articles from falling over (Japanese Patent Publication No. 51-49475). In this partition plate insertion device, sprockets are attached to a pair of rotating shafts arranged horizontally, and fall prevention members are attached horizontally at predetermined intervals to an endless chain that spans both sprockets to prevent the partition from falling. By transporting the prevention member around the sprocket and lowering it in an arc shape, the prevention member is inserted between the front and rear adjacent groups of articles in the conveying direction, thereby preventing the rear article in the front article group and the front article in the rear article group. We are making it possible to support each of these.

``Problem to be Solved by the Invention'' However, in the above configuration, the fall prevention member is lowered in an arc shape around the sprocket, so the fall prevention member that supports the front article in the group of articles is particularly If the product is lowered at a time when the product does not come into contact with the product in front of the product, there is a risk that the distance between the product and the product in front of the product will become insufficient and support will become insufficient, and this tendency was particularly noticeable for tall products.

``Means for Solving the Problems'' In view of such circumstances, the present invention includes a sprocket provided on each of a pair of rotating shafts, an endless chain stretched between both sprockets, and a sprocket provided at predetermined intervals on this chain. a plurality of first rods and a plurality of second rods, each of which is alternately connected to the rods and conveyed in a straight line while maintaining a vertical state in at least a part of the conveyance section; a partition plate insertion mechanism that forms an interval between the groups of articles grouped by the grouping mechanism and inserts a partition plate into the interval;
Each of the rods is provided so as to be movable up and down, and is inserted between adjacent groups of articles in the transport direction, and supports the rear article in the front article group and the front article in the rear article group, respectively. the first cam means for raising and lowering the partition plate insertion mechanism in the conveyance section; and the second cam means for raising and lowering the fall prevention member in the conveyance section; The cam means lowers the partition plate insertion mechanism from above toward the group of containers at a predetermined position within the conveyance section, and engages the partition plate insertion mechanism with the containers to form the gap, and The second cam means inserts the overturn prevention member from above into the middle of the adjacent container group before the partition plate insertion mechanism forms the interval.

"Function" According to the above configuration, the fall prevention member is lowered along the vertical second rod and inserted between adjacent container groups, so even if the product is tall, This prevents the article from being insufficiently supported due to the wide gap between the article and the article in front, as in the conventional case, and it is possible to reliably prevent the article from falling.

"Example" The present invention will be described below with reference to the illustrated example.
In FIGS. 1 to 4, reference numeral 1 denotes a transport conveyor that continuously transports cylindrical articles 2 in multiple rows, in the illustrated embodiment, five vertical rows, and 3 represents the objects transported by this transport conveyor 1. This is a grouping mechanism that groups the articles 2 that have arrived in two rows horizontally, that is, into a total of 10 articles vertically and horizontally.

The grouping mechanism 3 includes a chain 5 that is stretched between sprockets 4 and 4 at the lower part of the conveyor 1, and is attached to the chain 5 so as to be swingable at predetermined intervals so as to be conveyed integrally. Each grouping pin 6 is provided with a grouping pin 6 whose direction is controlled by a cam mechanism (not shown).
It is designed to be inserted so as to protrude from below between the two.

Each grouping pin 6 is caused to travel in the same direction by the chain 5 at a slower speed than the conveyor 1, so that each article 2 can be braked. Then, when the succeeding grouping pin 6 protrudes above the upper surface of the transport conveyor 1 and applies braking to the article 2, the preceding grouping pin 6 moves below the transport conveyor 1 and releases the brake on the article 2.
As a result, the ten articles 2 are conveyed at high speed by the conveyor 1, and a required distance l is formed between the ten articles 2 and the articles 2 that are braked by the subsequent grouping pins 6.

Therefore, a partition plate insertion mechanism 10 and a fall prevention member insertion mechanism 11 are provided at a front side position of the side part of the grouping mechanism 3. The partition plate insertion mechanism 10 includes a pair of rotating shafts 12, 12 (Fig. 2) arranged vertically and parallel to each other with a predetermined interval, and sprockets 13, 13 attached to each rotating shaft 12, 12, respectively. and a pair of upper and lower chains 14 that span each sprocket 13, 13.

Between the pair of upper and lower chains 14, a large number of sets of two parallel rods 15 are installed at equal intervals in the vertical direction, and a roller 16 (Fig. 3) is installed at the lower end of each rod 15. The rollers 16 are mounted so that they can roll on the rails 17. Then, the lifting frame 18 is attached to every other set of rods 15 so as to be able to rise and fall freely, and the cam follower 19 provided on this lifting frame 18 is engaged with the fixed cam 20, and the lifting frame 18 is moved along the shape of the fixed cam 20. 18 can be raised and lowered.

A pair of rotating shafts 21, 21 parallel to each other are supported on each of the lifting frames 18, and each of the rotating shafts 21, 2
1 is provided with rod-shaped gripping members 22, 22, respectively, so that the tip of each gripping member 22, 22 can be inserted between the grouped two horizontal rows of articles 2, and both gripping members 22, 22 When closed, the sheet-shaped partition plate 23 can be held between both gripping members.

Gears 24, 24 are fixed to the pair of rotating shafts 21, 21, respectively, and the gears 24, 24 are meshed with each other, so that the rotating shafts 21, 21 can rotate in mutually opposite directions. The gripping members 22, 22 can be opened and closed. And lever 2 is attached to one rotating shaft 21.
5 is fixed and a cam follower 26 is provided at the tip thereof, and by engaging the cam follower 26 with the fixed cam 27, the gripping member 2 is held at a desired position.
2 and 22 can be opened and closed.

A supply mechanism 30 is provided above the front of the conveyor 1 to sequentially supply the partition plates 23 one by one between the pair of gripping members 22, 22. This supply mechanism 30 includes a suction cup 32 that suctions the partition plates 23 stacked and stored in the magazine 31 using negative pressure.
and a swinging member 33 for moving the suction cup 32 between the outlet of the magazine 31 and a supply position where the partition plate 23 is dropped and supplied between the gripping members 22, 22.

Furthermore, a sliding plate 3 is provided at the tip of the conveyor 1.
4 are continuous, and guide plates 35 are provided on both sides of the sliding plate 34 to guide the falling of the partition plate 23. The guide plate 35 has the upper surface of the rear portion in the transport direction of the article 2 horizontally, and the upper surface of the front portion continuous thereto is inclined downward, and the partition plate 23 can be dropped according to the slope. That's what I do. Incidentally, slits 36 are formed at predetermined positions of the gripping members 22, 22 to avoid contact with the guide plate 35.

Next, the above-mentioned fall prevention member insertion mechanism 11 is integrated into the partition plate insertion mechanism 10, and the fall prevention member insertion mechanism 11 is inserted into each of the other groups adjacent to the rod 15 provided with the lifting frame 18. Rod 15
A cam follower 41 provided on the fall prevention member 40 is engaged with a fixed cam 42 to raise and lower the fall prevention member 40 along the shape of the fixed cam 42. I'm trying to be able to do that.

The fall prevention member 40 is made of a box-shaped member having a width slightly smaller than the interval between each group of articles grouped by the grouping mechanism 3,
When the partition plate 23 is inserted by the partition plate insertion mechanism 10, the article 2 is inserted within the interval so as not to fall. In addition, this fall prevention member 4
0 is also formed with a slit 43 to avoid contact with the guide plate 35.

In the above configuration, the articles 2 conveyed by the conveyor 1 are grouped into groups of 10 articles by the grouping mechanism 3, and a required interval l is formed between each group of articles. When the grouping mechanism 3 forms a required interval 1 between each group of articles, the fall prevention member 11 is lowered according to the cam curve of the fixed cam 42 and inserted into each interval 1.

On the other hand, the pair of gripping members 22, 22 provided on the lifting frame 18 are closed according to the cam curve of the fixed cam 27, and when the lifting frame 18 passes directly below the supply mechanism 30, the gripping members 22, 22 are closed. One partition plate 23 is supplied from the suction cup 32 between the two closed gripping members 22, 22. and gripping member 2
When the partition plate 23 is supplied to 2 and 22, the elevating frame 1
8 is lowered according to the cam curve of the fixed cam, and the lower ends of the gripping members 22, 22 are inserted between the articles 2 adjacent in the conveying direction.

In this state, the pair of gripping members 22, 22 are opened by the fixed cam 27, so the article 2 is pressed back and forth to form a gap between the adjacent articles 2, and at the same time, the gripping member 23 of the partition plate 23 is is released, so that the partition plate 23 falls into the gap between the articles 2 due to its own weight. At this time, the adjacent articles 2 are pushed apart by the gripping members 22, 22, but the overturn prevention member 40 is
Since the article 2 is located inside, the article 2 will not fall over. The partition plate 23 falling due to its own weight is caught by the upper surface of the guide plate 35, gradually falls along the slope formed in the front of the guide plate 35 in the transport direction, and is stored in the article 2.

Thereafter, the lifting frame 18 and the fall prevention member 40 are returned to their original upper positions, and the gripping members 22, 2
2 is also returned to its original closed state.

The grouped articles 2 are conveyed under pressure on the sliding plate 34 by the overturn prevention member 40, and before the overturn prevention member 40 moves upward, they are delivered to a conveyor (not shown) and the conveyance is carried out. It is designed to be transported by a conveyor.

Furthermore, in the partition plate insertion mechanism 10 of the above embodiment, a gap is formed between the articles by the gripping members 22, 22, and the partition plate 23 is dropped therein. It is also possible to use a partition plate insertion mechanism in which the plate is pushed into the partition plate.

Further, the grouping mechanism 3 is not limited to the one in the illustrated embodiment, and any suitable structure can be used as long as the articles 2 can be grouped into a required number of groups.

"Effects of the Invention" As described above, according to the present invention, since the overturn prevention member can be lowered along the vertical rod and inserted between adjacent container groups, the overturn prevention member and each container The distance between the objects in the group can be set to the desired distance, so even if the object is particularly tall, the distance between the overturning member and the object in front is wide and the support is insufficient as in the past. This provides the effect of reliably preventing the article from falling over.
