Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an inter-article partition plate insertion device for inserting a partition plate between adjacent articles.

``Prior Art'' Conventionally, devices with various configurations have been proposed as devices for inserting partition plates between articles. One type of device includes a pair of gripping members that can be opened and closed, and when the partition plate is inserted when the partition plate is closed, A device is known in which the partition plate is inserted between adjacent items when the item is gripped and opened.

In this type of partition plate insertion device, it is usually necessary to widen the gap between the articles in order to smoothly insert the partition plate between adjacent articles. Some devices are provided with an opening means and the gap widening means forms a gap between the articles.

Conventionally, as this gap widening means, sloped surfaces having a chevron-shaped cross section that are inclined in opposite directions are formed on the conveyance locus of the conveyance means that conveys the article, and the article being conveyed is positioned on both sloped surfaces. There is a device in which a V-shaped gap is formed between the articles by doing so (Japanese Patent Application Laid-Open No. 48-46491).

"Problems to be Solved by the Invention" However, in the conventional device with such a configuration, the inclined surface naturally becomes the bottom of the container, so a partition plate is inserted between the inclined surface and the container from above the container. As a result, it is necessary to construct the partition plate insertion means and the slope separately, and as a result, it is necessary to align the partition plate insertion means and the slope in the proper position, or to insert the partition plate after the container is positioned on the slope and a V-shaped gap is formed. It is necessary to set the operation timing of the partition plate insertion means so as to insert the partition plate, and the adjustment and maintenance inspection thereof become complicated.

"Means for Solving the Problems" In view of these circumstances, the present invention provides at least one of the gripping members with an extrusion member that presses the article when the gripping member is opened to form a gap between adjacent articles. It is something.

"Function" According to the above-mentioned configuration, a gap can be formed between the articles by the extrusion member simultaneously with the opening operation of the gripping member, so that it is possible to adjust the position of the gripping member and the extrusion member, adjust the operation timing, etc. becomes easier or unnecessary.

"Example" The present invention will be explained below with reference to the illustrated example.
In Fig. 1, a pair of shafts 1 and 2 are arranged horizontally and parallelly with a predetermined interval, a pair of sprockets 3 and 4 are attached to each shaft 1 and 2, and a pair of sprockets 3 and 4 are installed between each sprocket 3 and 4. A chain 5 is stretched parallel to the (see Fig. 2).

As shown in FIGS. 2 and 3, a plurality of substantially flat support members 10 are suspended between both chains 5 at equal intervals, and a pair of rollers 11 are rotated on both sides of each support member 10. It can be installed freely. As shown in FIG. 2 and FIG.
The straight portions of the support members 10 are engaged with a pair of upper and lower guide members 13 fixed to the machine frame 12, thereby making it possible to guide each support member 10 in a straight line.

As shown in FIGS. 2 and 3, each support member 10 has a pair of bearings 1 provided on both sides in the longitudinal direction.
4, an elevating frame 15 is attached to the elevating frame 15 so that it can be freely raised and lowered, and a pair of gripping members 16 and 17 are attached to the elevating frame 15.
has been established. Each of the gripping members 16 and 17 is formed into a rectangular plate shape, and one gripping member 16 located on the front side in the direction of conveyance by the chain 5 is fixed to the lifting frame 15, and the other gripping member on the rear side. 17 is rotatably provided via a rotating shaft 18. A spring 19 is provided between the gripping members 16 and 17 to normally close the gripping members 16 and 17,
The elastic force of the spring 19 allows the sheet-shaped partition plate 20 to be held between both gripping members.

Further, the tip of the rotatable gripping member 17 is connected to the push-out member 2 that abuts the upper end opening 21a of the article 21.
2, and an overturn prevention member 23 is attached opposite to this extrusion member 22 to support the article 21 from the opposite side of the article 21 and prevent it from falling when the extrusion member 22 presses the article 21. There is.

Next, each lifting frame 15 is provided with a first cam follower 30, and this cam follower 3
0 is engaged with the first cam member 31 fixed to the machine frame 12, the elevating frame 15 is lowered, and the tips of the gripping members 16 and 17 are held in the gap between the openings 21a of the adjacent articles 21 (the (See Figure 1).

On the other hand, an arm 32 is attached to the end of the rotating shaft 18 to which the gripping member is rotatably attached, and a second cam follower 33 is provided at the tip of the arm 32, and this cam follower 33 is fixed at the upper and lower positions of the machine frame 12. By engaging the two second cam members 34 or 35, the pair of gripping members 16, 17 can be opened against the force of the spring 19.

Furthermore, below the chain 5 is a conveyor 3 that conveys the article 21 along the conveyance direction.
6, and a supply mechanism 37 for sequentially supplying the partition plates 20 one by one between the pair of expanded gripping members 16 and 17 is provided above. Partition plate 2
Since the supply mechanism for supplying sheet-like members such as 0 one by one is conventionally well known, a detailed explanation of its structure will be omitted.

In the above configuration, in the illustrated embodiment, the conveyor 36 sequentially conveys a total of 10 articles 21 as one group, two in the conveying direction and five in the orthogonal direction to the conveyor 36 in synchronization with the chain 5. ing.

Each pair of gripping members 16, 17 is normally provided with a spring 19.
However, when the cam follower 33, which is interlocked with the gripping member 17 via the rotating shaft 18 and the arm 32, engages the upper second cam member 34, both the gripping members 16 and 17 are opened. When the gripping members 16 and 17 pass directly below the supply mechanism 37 in this state, the supply mechanism 37
When the partition plate 20 is supplied between both the gripping members 16 and 17, the cam follower 34 is inserted into the cam member 34.
Since the gripping members 16 and 17 are separated from the spring 1
9, and the partition plate 20 is gripped between them.

The gripping members 16 and 17 that gripped the partition plate 20 are then moved around the sprocket 3 and reversed so that their tips are directed downward. At this time, the cam follower 30 that raises and lowers the elevating frame 15 engages with the first cam member 31 from above around the sprocket 3, as shown in FIG.
When the tip of the lifting frame 15 is directed downward, the lifting frame 15 and therefore the gripping members 16 and 17 are held at the upper end position. In this state, the tips, that is, the lower ends of each of the gripping members 16 and 17 are at a height that does not come into contact with the articles 21, and the lower ends are positioned at the center position in the transport direction of the articles 21 of the one group. It's summery.

Next, the gripping members 16 and 17 are attached to the first cam member 3.
When the gripping members 16 and 17 are lowered, their lower ends are inserted between the openings 21a of adjacent articles 21 in the transport direction. At the same time, the anti-falling member 23 integrated with the gripping member 17 also descends to cover the opening 21a of the article 21 on the rear side in the conveyance direction, thereby becoming in a state where it can prevent the object from falling.

In this state, the cam follower 33 engages with the lower second cam member 35 and slightly rotates the gripping member 17 in the counterclockwise direction in FIG. comes into contact with the opening 21a of the article 21 on the rear side in the conveyance direction and presses it backward, thereby tilting the article 21 backward and forming a gap between the adjacent articles 21. At the same time, the gripping member 17 is rotated counterclockwise to release the grip on the partition plate 20, so that the partition plate 20 falls into the gap between the articles 21 due to its own weight. become.

When extruding the article 21 by the gripping member 17,
If the article 21 is pushed out more than necessary and is about to fall over, the overturn prevention member 23 prevents it from overturning and raises the article 21, so that the article 21 does not overturn. Further, since the lower second cam member 35 is formed with two cam surfaces for rotating the gripping member 17 in the counterclockwise direction, the operation of forming a gap between the articles 21 is performed twice in succession. This will ensure that the partition plate 2
0 can be inserted between the articles 21.

The gripping members 16 and 17 that have released the partition plate 20 are
After being raised by the first cam member 31, it is conveyed upward along the outer periphery of the sprocket 4, and the same operation as described above is repeated again.

Note that it is of course possible to employ various configurations as the fall prevention member 23.

"Effect of the invention" As described above, according to the invention, a gap can be formed between the articles by the extrusion member simultaneously with the opening operation of the gripping member, so that the position adjustment between the gripping member and the extrusion member can be performed. Adjustment of operation timing, etc. becomes easy or unnecessary, and maintenance and inspection thereof can be made easier than in the past.
