Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a squeeze pressure adjusting device for adjusting the squeeze pressure of a blade that scrapes off moisture etc. adhering to the surface of a photosensitive material such as photographic film or photographic paper.

[Background Art] For example, in a system for developing a roll of photographic paper after printing, after processing such as development and water washing, the developer is removed from the surface of the photographic paper using a blade before starting the next processing.

To remove the developing solution and washing water, it is necessary to bring a blade into contact with the surface of the photographic paper, scrape it off appropriately, and apply a squeeze pressure that does not apply unnecessary pressing force to the surface of the photographic paper.

Conventionally, the base of the blade was sandwiched between one mounting member and this mounting member was screwed to the device, and the squeeze pressure was adjusted when the blade was mounted to the device. At the time of adjustment, it is necessary to reattach the attachment member, and in the case of a developer tank, the rack must be removed, resulting in a large-scale work. If the squeeze pressure is weak, the developer and washing water cannot be scraped off sufficiently, and if the squeeze pressure is too strong, scratches may occur on the photographic paper. Non-uniform squeezing pressure causes drying spots, especially during drying, and causes defective products. In addition, the squeeze pressure changes as the blade deforms over time, so frequent squeeze pressure adjustments are required. Particularly when the blade is partially deformed, mounting adjustment cannot handle the problem, requiring the squeeze blade to be replaced, making the work even more difficult. .

[Purpose of the invention] Taking the above facts into consideration, the object of the present invention is to obtain a squeeze pressure adjusting device that can easily adjust the squeeze pressure.

[Summary of the invention] In the squeeze pressure adjustment device according to the invention, the blade base is divided into a plurality of holders in the width direction and supported, and the holders are accommodated in the support member, and the support member has a corresponding one. A guide elongated hole is formed in the squeeze pressure adjustment direction (rotation angle direction of the holder) so that the operator can adjust and lock the position of the adjustment handle, which stands up from the holder and passes through the guide elongated hole, relative to the elongated hole. It's summery.

As a result, the operator can obtain the desired squeezing pressure of the blade by operating the individual adjustment handles as necessary to adjust and move them to appropriate positions along the guide elongated hole, and then locking the blades to the support member. This makes adjustment much easier.

[Implementation of the Idea] Figures 1 and 2 show a state in which a roll of photographic paper 10 is drawn out from a developer (not shown) and is conveyed vertically upward, with blades 12 corresponding to the front and back sides.

This blade 12 has a contact portion 12A made of flexible rubber or the like that can come into contact with the photographic paper 10 over the entire width direction of the photographic paper 10.
The base 12B is made of plate-shaped synthetic resin or the like.

The base portion 12B is supported by a plurality of holders 14 as also shown in FIG. These holders 14 are made of synthetic resin pipes, and have a notch 14A formed in a part of their circumference.
The base 12B is inserted from 4A. Further, a plurality of holders 14 are arranged in the width direction of the base portion 12B, thereby supporting the base portion 12B in the width direction.

These holders 14 are accommodated and supported within support members 16 and 18. Support member 1
As shown in FIG. 2, 6 has a mounting piece 20 extending from the end of the cross-sectional shape of about a half arc,
The support member 18 has a mounting piece 22 extending from the end of the approximately one-quarter arc plate. These mounting pieces 2
When 0 and 22 are fixed with screws 26 with a bracket 24 protruding from the machine base (not shown) in between, they form a cylindrical member with a cross-sectional shape of about a quarter of an arc as shown in FIG. The holder 14 can be accommodated coaxially. Therefore, the holder 14
are rotatable coaxially within the support members 16 and 18.

The support member 16 is provided with guide elongated holes 28 corresponding to the plurality of holders 14, respectively. This guide elongated hole 28 is longitudinal in the circumferential direction of the holder 14, and this longitudinal direction is the squeeze pressure adjustment direction (holder rotation angle direction). These guide long holes 28 are connected to the screw holes 14 of the holder 14.
The threaded portion 3 of the adjustment handle 30 is screwed onto B and stands upright.
0A passes through it. Head 30B of adjustment handle 30
has a diameter larger than the width dimension of the guide elongated hole 28, and by screwing the threaded portion 30A into the holder 14, its end surface presses the periphery of the guide elongated hole 28, and the holder 14 can be locked to the support members 16, 18. It's becoming like that.

Next, the operation of this embodiment will be explained.

The operator rotates the head 30B of the adjustment handle 30 to separate it from the periphery of the guide elongated hole 28. This allows the holder 14 to rotate within the support members 16,18. Here, the pressing force of the contact portion 12A against the photographic paper 10, that is, the squeeze pressure is adjusted. This squeeze pressure adjustment can be performed by gripping the contact portion 12A, or by moving the head 30B in the longitudinal direction of the guide elongated hole 28.

After adjusting the squeeze pressure, attach the threaded part 30A to the holder 14.
When the head 30B is screwed in, the head 30B is pressed against the periphery of the guide elongated hole 28, so the holder 14 rotates the support members 16, 18 at a desired rotation angle in the squeeze pressure adjustment direction.
It is locked to.

Therefore, the squeeze pressure is adjusted appropriately, and the photographic paper 1
0 continuously in the direction of arrow A, photographic paper 10
It is possible to scrape off the developer adhering to the surface and reduce the amount of developer carried to the next process, thereby reducing the amount of developer consumed.

If the squeeze pressure changes due to deformation of the contact portion 12A after a predetermined period of use, the head 30
Appropriate squeezing pressure can be obtained by loosening B, making fine adjustments in the longitudinal direction of the guide elongated hole 28, and then screwing it back in.
Therefore, even if the blade 12 is slightly deformed, it can be used for a long period of time.

Such adjustment of the squeeze pressure can be performed for each of the plurality of holders 14 provided in the width direction of the photographic paper 10, and thereby the squeeze pressure can be adjusted uniformly or partially consciously in the width direction of the photographic paper 10. It is possible to obtain a squeeze pressure that is varied.

Although the above embodiment shows a structure in which the present invention is used in the process of scraping off the developing solution adhering to the photographic paper 10, the present invention can of course be applied to other processes, and as an example, especially after washing with water. It is important to use it in the process of scraping off water in order to prevent dry spots during the drying process.

Although the above embodiment shows a structure in which the adjustment handle presses the peripheral edge of the guide elongated hole in the radial direction of the support member 16, the adjustment handle 30 is not limited to a screw, but a cam structure or the like can also be applied, and the part to be pressed is It is not limited to the periphery of the guide elongated hole, but may be other parts such as the inner periphery. Furthermore, although the above embodiment has a structure in which the adjustment handle can be moved steplessly in the direction of adjusting the squeeze pressure, it may be structured so that it can be adjusted in multiple steps for each minute length.

[Effect of the invention] As explained above, in the squeeze pressure adjustment device according to the invention, the holder is divided into a plurality of holders in the direction along the squeeze side of the blade, and the rotation angle of this holder is adjusted to the support member of the adjustment handle of each holder. The structure allows the holder to be locked to the support member at an appropriate position by individually adjusting the blades, which has an excellent effect of making it easy to adjust the squeeze pressure on the blade, especially on a partial part of the blade. has.
