Description

  The present invention relates to an apparatus for attaching a cover film, and more specifically, a specimen having a predetermined length by being drawn from a wound body in which a long cover film is wound on a specimen specimen attached to a glass slide and dropped with an encapsulant. It is a cover film sticking apparatus which sticks the cover film piece cut | disconnected to 1 and Comprising: Comprising: It is related with the cover film sticking apparatus provided with the process means of the cover film piece which is not used for sticking.

In a pathological examination, after attaching a thin section obtained by slicing a biomaterial to a slide glass and performing a staining treatment, a cover film piece (hereinafter referred to as a film piece) is applied to the surface of the slide glass to protect the thin section. Adhering and observing with a microscope is performed.
A cover film sticking device for sticking a film piece to a slide glass (hereinafter referred to as a sticking device) is a basket mainly used for accommodating a plurality of slide glasses before sticking and a slide glass after sticking. A basket standby means for waiting, a basket storage tank in which the basket is stored, a cover film supply means (hereinafter referred to as supply means) in which a cover film (hereinafter referred to as film) is stored, and a supply from the supply means It comprises cutting means for cutting the film into a predetermined length, and sticking means for dropping a solvent on a slide glass supplied from the basket to stick a predetermined length of film piece.

  In order to attach the film piece to the slide glass by this attaching device, the slide glass is placed on the attaching means for attaching the film piece from the basket accommodated in the basket standby means, and the film is supplied from the supplying means. It supplies to a cutting | disconnection means, cut | disconnects to predetermined length, applies the appropriate force to the slide glass wet with the solvent beforehand, and sticks the cut | disconnected film piece. After pasting, the pasted glass slide is stored in the basket.

  By the way, in this sticking apparatus, when it becomes impossible to supply the film from the wound body, the wound body in use is replaced with a new wound body in which the film is wound for a sufficient length. Will be replaced. The operator removes the winding body in use at the winding body installation location in this sticking device, attaches a new winding body to the winding body installation location, and takes out the top of the film from this winding body. Then, it is sent to the cutting means via a feed roller provided in the sticking device.

In FIG. 2, the top portion of the cover film 4 pulled out from the wound body may be dirty or scratched on the fingers for securing the redundant cover film when replacing the wound body, and may not be suitable for sticking. In many cases, the film placed on the film support 14 is cut from the film support 13 through the cutting means to be cut by the cover film cutting means 8 (hereinafter referred to as the cutting means 8) in order to remove the corresponding part. Film pieces may be discarded. Moreover, the film piece for sticking is cut after sending the film a predetermined length in the direction of the cover film sticking means 16 from the beginning of the film between the wound body and the cutting means after cutting. It is obtained by cutting by means 8. That is, the film cutting operation also serves as a reference operation for a predetermined length for obtaining a film piece having a predetermined length. In this positioning, the operator sends the film toward the film support 14 with care so as to be shorter than the length of the gap between the cutting means 8 and the film support 14.
Since the film piece generated by the cutting operation is a film piece that is not used for sticking to the slide glass, it should not be left on the film support 14. When the length of the film piece unsuitable for sticking is shorter than the gap between the cutting means 8 and the film support base 14, it is dropped and removed from the gap. However, when the length of the film piece is longer than the gap, the film piece remains on the film support 14 without falling from the gap, so that the operator covers the cutting means 8 and the cover film adhering means 16. Is opened and removed. When removing the film piece, the operator may be exposed to a harmful solvent gas such as xylene used for attaching the film piece. Also, the removal work of the film piece is a troublesome work for the operator. Furthermore, it is troublesome and troublesome to perform the work while confirming that the length of the film piece is shorter than the gap in the base pointing operation of the film piece.
That is, the problem to be achieved by the present invention is to reduce the labor of the removal of the film piece that the operator does not use for sticking in the cover film sticking apparatus, and further to the removal of the film piece. It is to reduce the adverse effect of the solvent gas on the worker.

In order to solve the above problems, the present inventor considered that it was effective to control the gap between the cutting means when cutting the film and the film support on the film sticking side, and as a result, The invention has been reached.
That is, the present invention sends the cover film from a wound body wound with a long cover film to a cutting means, cuts the cover film by the cutting means to form a film piece, Thus, a cover film sticking apparatus for sticking the film piece to a slide glass to which a thin slice specimen is attached, wherein the film piece not used for sticking to the slide glass is removed from the cutting means. The cover film sticking apparatus is provided with a removing means that guides and removes from a portion reaching the attaching means.

  Further, the present invention is the cover film support base in which the removing means is disposed in a portion from the cutting means to the sticking means, and the clearance between the cutting means and the cover film support base is adjustable. It is in the cover film sticking apparatus.

  Moreover, this invention exists in the cover film sticking apparatus with which the said cover film support stand is rotatable.

  Furthermore, this invention exists in the cover film sticking apparatus which has the control means which controls rotation of a cover film support stand so that the film piece which is not used for sticking to a slide glass may be removed below.

  At the time of removal work by cutting a film piece that is not used for sticking, it is not necessary to pay attention to cut it shorter than the gap between the cutting means and the film support as in the past, and the top of the cover film Since it cut | disconnects after confirming that it contact | abutted to the film support stand which blocked | interrupted progress from the cutting | disconnection means, it is not an effort. Moreover, since the film piece is located below the film support base, the film piece does not remain on the film support base and falls. As a result, there is no need to open the door and remove the film piece, and the operator is not exposed to the organic solvent.

The cover film sticking apparatus of this invention is demonstrated with reference to FIG. 1A is a front view showing an outline of the apparatus of the present invention, FIG. 1B is a plan view of the apparatus viewed from above, and FIG. 1C is an enlarged front view of a film piece removing means. Yes.
The adhering apparatus of the present invention mainly includes a cover film supplying means 1 for supplying the cover film 4 to the adhering means 16, a cutting means 8 for cutting the cover film 4, and an adhering means 16 for adhering the film pieces. Provided, and each is supported by a base 17. The cover film supply unit 1 includes a wound body 2 around which at least a long cover film is wound, a guide roller group 3 for routing a redundant film, and a drawing roller 6 for supporting the wound body 2. The sticking means 16 includes at least a cover roller 11 for sending a film piece to the sticking roller 12, a dispensing means (not shown) for dropping a solvent on the slide glass 10, and a film piece placed on the slide glass. It is comprised from the sticking roller which presses and sticks from.
Furthermore, the sticking apparatus of the present invention includes a feed roller 7 that feeds the cover film 4 from the wound body 2 to the cutting means 8, a support base 13 that supports the cover film 4 positioned between the feed roller 7 and the cutting means 8, and A base film 17 supports a cover film 4 before cutting and a film support 14 for supporting a film piece after cutting, which are provided between the cutting means and the cover roller 11 and used for sticking.
In addition, the film support base 14 has an inclination angle D with respect to a plane including the contact surfaces of the pair of feed rollers 7 and the contact surfaces of the pair of cover rollers 11. The base 17 is rotatably supported so as to form The inclination angle D is defined as an angle formed on the upper side with respect to a plane including the contact surfaces of the pair of feed rollers 7 and the contact surfaces of the pair of cover rollers 11, and an angle formed on the lower side as-. Then, it is possible to form between -360 degrees and +360 degrees.

When processing a film piece that is not used for sticking, the cutting means 8 and the film are rotated by rotating the film support 14 so that the inclination angle D becomes + so as to block the progress of the leading portion of the film 4. The gap between the support bases 14 is lengthened. In order to block the progress of the leading portion of the film 4, the film support 14 is preferably rotated and stopped so that the inclination angle D becomes an acute angle.
When the gap between the cutting means 8 and the film support base 14 becomes long, the film 4 is passed over the cutting means 8 by the feed roller 7 until the top of the film 4 comes into contact with the film support base 14 that blocks the progress of the film 4. Feed and cut by the cutting means 8. The cut film piece falls into the waste container 15 placed below from the gap. When the part which is not used for sticking is long, the operation of cutting the film 4 until it abuts against the film support 14 is repeated.
Preferably, the inclination angle D is reduced so that the top surface of the top portion of the film 4 is pressed by the portion on the cutting means side of the film support 14 after the top of the film 4 contacts the film support 14. 4 is cut stably.
Further, preferably, a narrow plate is disposed between the cutting means 8 and the film support 14 so as not to obstruct the progress of the film 4, so that the film support 13 and the width can be reduced when the film 4 is cut. The film 4 is supported by sandwiching the cutting means 8 with a narrow plate, and the film 4 can be stably cut.
Further, after the film is cut, the film support base 14 can more stably guide the cut film piece downward by setting the inclination angle D to the-side or-.

  When the processing of the film piece not used for sticking is finished, the film support 14 is rotated and stopped so that the angle becomes 0 degree. Since the base point for obtaining the predetermined length of the film piece is obtained by the processing of the film piece not used for sticking, the film 4 is covered by the feed roller 7 by the predetermined length through the cutting means 8. A film piece suitable for sticking can be obtained by feeding to the roller 11 and cutting with the cutting means 8. Subsequent sticking operations are performed in the same manner as in the past.
