Abstract

PURPOSE:To fold a film in a continuous length in an accordion shape by controlling the movement of both No.1 hanger group which is moved to the directions normal to and parallel with the film carrying direction, and No.2 hanger group which is moved only to the direction normal to the film carrying direction. CONSTITUTION:A folding control circuit 100 permits a rimpled film 1 to be folded by feeding the film while the film 1 is being held by No.1 hanger group 21 so as to have the support of the folded film 1 replaced with No.1 and No.2 hanger groups 21 and 22 moved to the direction normal to the film carrying direction. Then, No.1 hanger group 21 permits the film 1 supported by No.2 hanger group 22 to be moved to the direction reverse to the film carrying direction, and to be moved to the vertical direction thereafter so as to support the film again repeatedly. By this constitution, when the operations set forth herein above are repeated by No.1 and No.2 hanger group, the film can thereby be folded into an accordion shape in order.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film folding device capable of folding a long film smeared with a sample such as blood.

[Prior Art] Generally, when examining pathological tissue samples such as blood in hospitals, etc., the sample is smeared on a glass plate, dried and stained,
This sample is inspected using a microscope or the like. In recent years, in hospitals and other facilities that test large quantities of smear samples, this smearing process must be performed by a skilled clinical laboratory technician to maintain a certain quality of the specimen, and the glass plates on which the samples are smeared also require a large amount of storage space. Therefore, an automatic smearing device that automatically smears a flexible film has been proposed.

The storage space is, for example, about 1.2I thick and about 5g in weight.
In the case of a hospital that uses 300 smear glasses per day, a storage space of 548 kg and a height of 131 m is required per year.

Automatic sample (blood) smear devices according to the prior art are disclosed in, for example, Japanese Patent Application Laid-open Nos. 49-117130 and 52-178.
This method has been proposed in Japanese Patent Publication No. 84 and Japanese Patent Application Laid-open No. 152282/1984. These smear devices are compatible with a flexible film for dripping onto which blood is dripped while being transported, and a blood smearing device where blood is smeared by being transported in the opposite direction while contacting the flexible film for dripping. A flexible film is provided to continuously and automatically drip or smear blood. A device using this smear film is lighter and smaller than a conventional device using a glass plate, making it easier to store specimens.

[Problems to be Solved by the Invention] Although this automatic smearing device according to the prior art is capable of automatically dropping and smearing blood, it has only been disclosed as far as winding up a flexible film smeared with blood; There is no mention of the subsequent staining process. Since the flexible film in this rolled state is in close contact with each other,
In order to carry out the staining process, there was a problem in that it was necessary to either stretch the specimen or cut it into individual specimens.

An object of the present invention is to eliminate the problems caused by the prior art, and to provide a film folding device that has a simple configuration and can fold a film smeared with a sample such as blood to facilitate staining. It is to be.

[Means for Solving the Problems] In order to achieve the above object, a film folding device according to the present invention includes a press mechanism that creates creases at predetermined intervals on a long film coated with a sample, and a plurality of press mechanisms that support the film. a first hanger group that has hangers and moves in a direction perpendicular and parallel to the film transport direction, and a second hanger group that has a plurality of hangers that support the film and moves only in a direction perpendicular to the film transport direction. A control circuit was provided to control the feeding of the film and the movement of the first hanger group and the second hanger group.

[Function] The control circuit bends the film by feeding the film with the creases supported by the first hanger group, and transfers the folded film to the first hanger group and the first hanger group. The second hanger group is moved in a direction perpendicular to the film transport direction to replace the support, and the first hanger group is moved in a parallel direction opposite to the film transport direction and perpendicular to the film supported by the second hanger group. Repeat the motion of moving in the direction and supporting again.

Therefore, the film folding device according to the present invention can sequentially fold the film into an accordion shape by repeating the above-mentioned operations of the first and second hanger groups.
