Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a conveyance device that conveys a sheet bundle formed by stacking a plurality of sheets.

(Prior art) In the process of processing sheet materials such as paper, metal plates, and plastic films, a long web is continuously cut into multiple sheets of fixed length, and these sheets are stacked to form a sheet bundle. Thereafter, the sheet bundle is often transported to a predetermined position, and the transported sheet bundle is transported to the next process.

The above-mentioned transfer operation is generally carried out by a belt conveyor, a roller conveyor, etc., but in addition to these, the above-mentioned transfer operation can also be carried out by a carrier with a chuck, etc. as disclosed in JP-A-59-217542. It is.

(Problems to be Solved by the Invention) However, when a sheet bundle is conveyed by the belt conveyor, roller conveyor, etc., there is a possibility that the sheet bundle may break during conveyance, and the mechanism for passing the receiver to each station is complicated. There was a problem. The proposal described in the above publication is a sheet bundle separation and feeding device that can automatically take out a predetermined number of sheets from a sheet stack at once, and stably transports the sheet bundle between stations. This point was not taken into account.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sheet bundle conveying device that has a simple structure and can stably convey and supply sheet bundles of various sizes between stations. do.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a sheet bundle conveying device that conveys a sheet bundle formed by stacking a plurality of sheets between a plurality of stations. The bucket on which the sheet bundle is placed and transported is formed into a plate shape so as to be able to pass through a gap formed in the sheet bundle loading table of the station, and the loading surface of the bucket for the sheet bundle is curved in a concave shape. be.

(Function) According to the above configuration, when the plate-shaped bucket on which the central part of the sheet bundle is placed is conveyed to the gap of the station, it is lowered and the sheet bundle is placed on the sheet bundle loading section of the station. can be placed. At this time, since the sheet bundle mounting surface of the bucket is curved in a concave shape, the sheet bundle is similarly curved and supported, and does not sag to both sides of the bucket.

Therefore, the sheet bundle does not interfere with the sheet bundle mounting table of the station, and can be easily conveyed. Furthermore, sheet bundles of different sizes can be conveyed by the same bucket, and the conveyance device can be made into a small and simple mechanism.

(Embodiment) Hereinafter, an embodiment of a sheet bundle conveying device according to the present invention will be described with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1 and 2. FIG.

In this embodiment, a case where the present invention is applied to an X-ray film processing process as shown in FIG. 2 will be explained.

The cono process is the supply section 1. Film alignment section 2. First cut portion 3. Second cutter section 4. It consists of a discharge section 5, and a bucket 7 sequentially transports about 100 film bundles 6 placed on the supply section 1 to the next process.

Four buckets 7 are provided on a movable plate 8 at the same pitch as the gaps between the stations 1, 2, 3, and 4.5, and this movable plate 8 can be moved forward and backward by one pitch by a driving means (not shown). It is supposed to be done. The four buckets 7 are made of a plate member with a thickness of approximately 50 mm, and are formed to penetrate through the center of the width direction of the sheet bundle mounting table 9 of each of the stations 1 to 5 in parallel to the conveyance direction. It is possible to pass through the gap 10.

The supply section 1 also has alignment plates 11 arranged at right angles to each other.
12, and the film aligning section 2 is provided with aligning plates 15.1 each driven by a cylinder 13.14.
8 and fixed alignment plates 17,18 are each provided at right angles. Also, the first and second cutter parts 3, 4
are provided with corner blades 19, 20 and 21, 22 and a notch blade 23, respectively.

As shown in FIG. 1, the bucket 7 is guided by two guides 24 provided on the movable plate 8 so as to be able to move up and down at a constant stroke, and is driven up and down by a cylinder 25. . A clamp arm 26 is rotatably provided at one end of the bucket 7 and is driven by a cylinder 27 attached to the moving plate 8. The clamp arm 2B clamps one end of the film bundle 6 placed on the bucket 7 while the bucket 7 is moving. Further, reference numeral 28 denotes a guide attached to the main body of the device that guides the movement of the movable plate 8. Furthermore, the upper surface of the bucket 7 is a curved surface 2 with a concave center in the longitudinal direction.
9, and the radius of curvature R of this curved surface 29 is approximately 60
It is 0mm.

Next, the operation of this embodiment will be explained. First, about 100 sheets of film cut to a certain size are placed on the sheet bundle mounting table 9a of the supply section 1, and the two sides are placed against the alignment plates 11 and 12 to align them. Next, the cylinder 25 is actuated to raise the bucket 7a, project it upward from the gap 10a, support the center of the film bundle 6 in the width direction by the curved surface 29 of the bucket 7a, and remove it from the sheet bundle mounting table 9a. let Then, the moving plate 8 is moved in the direction of arrow A, and the bucket 7a is conveyed to the next film aligning section 2. At this time, bucket 7
a is a gap formed in the sheet bundle mounting table 9b of the film alignment section 2], enters Ob, and stops at a predetermined position. Since the film bundle 6 is curved upward during this conveyance, rigidity is added to the film bundle 6, so that it does not sag on either side of the bucket 7a. Next, the bucket 7a is lowered by the operation of the cylinder 25, and the film bundle 6 is placed on the sheet bundle mounting table 9b.

The lowered bucket 7a moves in the direction of arrow B together with the movable plate 8 and stops at the lower part of the supply section 1, and at the same time, the bucket 7b reaches the lower part of the film alignment section 2 and is on standby. In this film alignment section 2, the film bundle 6 is aligned by cylinders 13,14. Thereafter, the film bundle 6 is similarly conveyed to the first cutter section 3, where the two adjacent corners are cut round by the corner blades 19 and 20, and at the same time, a notch hole is formed by the notch blade 23. Further, the sheet is conveyed to the second cutter section 4, where the remaining two coaters are corner cut by the corner blades 21 and 22, and finally conveyed to the discharge section 5. Then, the film bundle 6 that has been corner cut and notched is taken out of the machine from the discharge section 5. Note that while the film bundle 6 is being transported by the bucket 7, the cylinder 27 is operated and the film bundle 6 is clamped to the bucket 7 by the clamp arm 26 to prevent the film bundle 6 from shifting during transport. .

According to this embodiment, a curved surface 29 is formed on the upper surface of the small plate-shaped bucket 7, and the film bundle 6 is supported and conveyed by this curved surface. It is possible to prevent the film bundle 6 from sagging which occurs when the top surface is made flat, and the film bundle 6 can be prevented from sagging during transportation.
It is possible to reliably transport the sheet bundle without interfering with the sheet bundle mounting table 9 or the like. Therefore, the structure of the conveyance device can be made small and simple, and failures can be eliminated and costs can be reduced. Moreover, even if the size of the film bundle 6 changes, it can be easily transported using the same bucket 7, and the design space of the entire apparatus can be increased.

In the above embodiment, the curved surface 2 formed on the upper surface of the bucket 7
9 is about 600 mm, but in this case, the center of the radius of curvature does not need to be at the center in the width direction of the film bundle 6 as shown in FIG. 4, and the vertical line passing through the center is the center of the film bundle 6. It is enough if it passes through 6. However, as shown in FIG. 5, if the vertical line passing through the center does not pass through the film bundle 6 and the radius of curvature is about 1000 mm, it becomes impossible to prevent the film bundle 6 from sagging. This radius of curvature may be appropriately selected depending on the rigidity of the film bundle 6 placed on the bucket 7. Further, a product holding member may be provided to clamp the film bundle 6 placed on the sheet bundle mounting table 9 of each station during processing. Furthermore, in this example, 5
We have described a conveying device for sheet bundles installed in an X-ray film processing process that has two stations.
The number of stations is not limited to five, and the transported member is not limited to X-ray film.

(Effects of the Invention) As described above, according to the present invention, the loading surface of the sheet bundle of the bucket on which the sheet bundle is placed and conveyed is formed to be concavely curved. It is possible to stably transport and supply sheets between stations without causing any sag in the bundle, and furthermore, sheet bundles of various sizes can be transported by the same device.
