Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention streamlines the process of inserting and packaging paper inserts to protect sheet films such as X-ray films and professional color photosensitive materials from pressure and scratches. Concerning what to do.

[Conventional technology]

Conventionally, the sandwich paper 13b as shown in FIG. 2 has a chemically stable composition and moisture content with respect to photographic film, and does not cause fogging, static, or scratches even in extremely low or high humidity conditions. It is made to be able to exhibit a protective function against the like, and is packaged with a sheet film 54 sandwiched therebetween, as shown in FIG.

Then, the sandwich paper is twice the length of the sheet film, cut to a length using a cutting machine, etc., folded in half using a paper folding machine, and stacked in the workshop.

On the other hand, sheet films such as X-ray films are cut to a predetermined length from a long roll film of a predetermined width, and in some cases, the four corners are cut, and the sheets are stacked in a workshop.

Then, the operator takes out the film and the sandwich paper one by one in the darkroom work area, repeats the packaging process of inserting the film into the bifold sandwich paper, arranges the predetermined number of packaging units, wraps the top and bottom with a padding ball, and then wraps the film and sandwich paper one by one. They were shipped to the market in moisture-proof packaging with paper laminated with aluminum wheels, etc., and then packed in boxes.

Process machines include slitter, corner cutting machine, and other folding machines and paper folding machines.

[Problem to be solved by the invention]

As mentioned above, in order to insert a sandwich paper into a sheet film, there is a process of cutting a long roll film of a predetermined width into a predetermined length to make a sheet film of a predetermined size, and a long roll of the same width as the sheet film. Either cut out a sandwich sheet having a length twice the predetermined length of the sheet film from a roll of paper, or use a decorative cutting machine to cut a sandwich sheet of a predetermined size from sheets of paper that have been cut into large sheets and stacked in advance. After the process of cutting out the paper sheet and the process of continuously feeding it one sheet at a time to a paper folding machine to make a sandwich paper that is folded in half, one side of the sheet film and the sandwich paper made in these processes is further processed. It was necessary to manually insert the one into the other. The packaging process of inserting sheet film into two-fold sandwich paper consists of several types.
It required a large amount of man-hours and was inefficient.

It is an object of the present invention to eliminate such drawbacks and provide a highly efficient sheet film inserting and packaging device for inserting paper.

[Means to solve the problem]

The purpose of this is to continuously convey a sandwich paper that is twice the length of the sheet film, and when the tip of the sandwich paper hits the stopper, the sandwich paper buckles and the center part of the sandwich paper stops. The sheet film is conveyed at a timing such that the sheet film is bitten by the folding roller member and begins to be folded in half, and the sheet film also begins to be bitten and inserted into the sandwich paper, thereby completing the folding process of the sandwich paper and the sheet film. This is achieved by a sheet film sandwich paper inserting and packaging device characterized in that the step of inserting the sheet film into the sandwich paper is continuously carried out in one device.

〔Example〕

One embodiment of the device of the invention is shown in a schematic front view in FIG.

This device is a core 1 of a long roll 13 for sandwich paper having a predetermined width.

A first transport conveyor 30 consisting of an endless belt 3438 wound around 6.37 and drive rollers 42, 44 . A second conveyor 40 consisting of endless conveyor belts 45 and 46 wound around driven rollers 41 and 43, a vertically movable lifting platform 53, and a sheet film storage case 51.
Rear stopper 52 for size adjustment, pickup roller 5
5. A sheet film supply section 50 consisting of a pair of feed rollers 56 and 57, and a drive roller 6L driven rollers 62 and 63
A /- film transport conveyor 60 consisting of an endless belt 64 wound around the sheet film, and an introduction unit 74 for introducing the sandwich paper 13a before being folded, which is measured to be twice the length of the sheet film and consisting of guide members 74a and 74b. Guide member 7
5a, 75b and a stopper member 78, a sheet film introduction chute 7G consisting of guide members 76a, 76b, a pair of paper feed rollers 71, 72, and a pair of paper folding rollers 72, 73, which rotate in the directions of the arrows, respectively. , a paper folding film insertion section 70 having a discharge guide 77, and a drive roller 81. Followed rollers 82, 8
The collection conveyor 80 is composed of an endless belt 84 wound around the container 3, and a collection case 90 having a tray 92 and a rear stopper 93.

Next, the operation of the apparatus of this embodiment will be explained.

The sandwich paper fed out from the long roll 13 at a constant speed by a pair of feeding rollers is cut to a length twice the film length Q by a measuring cutting device 20. In this case, it is possible to easily change the size by changing the time for one rotation of the rotary cutter 21, 24 according to the required measuring length cutting length 2Q, and by adjusting the circumferential speed of the cutter during cutting to match the paper feed speed. That's how it is. The sandwiched paper 13a, which has been cut to a measured length, is transported within the first transport conveyor 30 at the same speed as the previous delivery speed and fed into the second transport conveyor 40. Second transport conveyor, paper feed roller pair 71
72 and the conveyance speed V of the paper folding rollers 72 and 73, (
mm/5ec) is the conveyance speed of the first conveyor V + (
mm/5ec), and on the exit side of the first conveyor, the conveyor belt 34.3
Since there is a gap between 8 and 8 as shown in FIG. 1, the conveyance force decreases and the leading edge of the leading sandwich paper 13a hits the stopper 78; sometimes the trailing edge of the sandwich paper 13a and the leading edge of the following sandwich paper collide. There is an interval of -(+mm) between them. This step a allows you to fold the next sandwich paper and insert the film.
c) After a while, the leading edge of the following sandwich paper reaches the running path of the sheet film and intersects with it. At this time, since the sheet film has already passed through the running path, troubles such as jams due to overlapping of the sandwiched papers or collision between the sandwiched paper and the film do not occur.

On the other hand, from the sheet film supply section 50 to the sheet film 54
However, the pickup roller 55 and the feeding roller pair 5
At 6.57, the sheets are sent out one by one and conveyed onto the sheet film conveyor 60. The linear speed V of the conveyor 60 is set higher than the linear speed of the feed roller pair 56 and 57, and the interval between sheet films of length C on the transport conveyor is set to be Q+a. ing. Note that the linear velocity V3 is equal to the paper conveyance velocity V2.

As mentioned above, the tip of the sandwich paper 13H is connected to the stopper 78.
At the moment of contact, the leading edge of the sheet film 54 reaches near the right end of the chute 76, and comes into contact with the center of the sandwich paper +3a.

Then, the fold line of the sandwich paper synchronizes with the leading edge of the sheet film, becomes one, is bitten by the paper folding rollers 73 and 72, and advances to the right, resulting in the state shown in FIG. The sheet film 54 is inserted and stored in the collection case 90 via the collection conveyor 80, and this process is automatically repeated to complete the sandwich paper insertion and packaging of the sheet film.

In this embodiment, the sandwich paper is cut from a long roll paper to a length of 2Q while being processed.In this case, the sandwich paper 13a, which has already been cut to a length of 2Q, is stacked. It is also possible to pick up one sheet at a time and feed it to the first conveyor 30, and the present applicant also has such an embodiment.

Furthermore, in this embodiment, the sheet films 54 are picked up one by one from the stack and sent to the sheet film transport conveyor 60, but instead of this, a film of a predetermined length Q is cut to a meter from a long film roll. However, it is also possible to send the sheet film to the conveyor 60, and the applicant has successfully developed such an embodiment.

Therefore, both film and sandwich paper can be processed from long rolls, or both can be fed one by one from a loaded object.

Alternatively, a method may be adopted in which the film is processed from a long film roll, and the film is inserted one by one from a sheet loaded with sandwich paper to form the sandwich paper.

Note that the means for cutting the sandwich paper and film is not limited to the means for cutting the sandwich paper and film using a rotary cutter as in this embodiment.

〔Effect of the invention〕

The present invention provides an apparatus that replaces the processing process in which the wrapping paper and stacked sheet film were folded in separate processes, and the sheet films were inserted one by one into the sandwich paper in a separate process. This makes it possible to combine each of these processes into one process and perform it quickly, efficiently, automatically, reliably, and safely.
