Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film winder for winding and storing a film.

[Conventional technology]

Photographic films, particularly negative films, are sometimes produced by connecting and bonding negative films of a plurality of orders (for example, a plurality of customers) in the longitudinal direction, winding them into a single long film in layers, and then developing the film. As a result, the negative film can be automatically transported into the developing device by simply guiding the leading edge with the league.

In addition, in a small lab, the films are processed one by one without being joined together.

[Problems to be Solved by the Invention] However, joining a plurality of negative films is a complicated and time-consuming task. Furthermore, the method of processing books one by one without joining them is similarly labor-intensive. For this reason, it is possible to wind multiple negative films onto a single reel without splicing them together, but if you wind multiple negative films onto a single reel without splicing them together, the negative films may rub against each other. This is not desirable as it may damage the image surface. In addition, it is possible to wind a single negative film onto separate reels as an alternative method for developing without joining, but in this case, it is necessary to attach and detach the reels in the developing device. This does not improve work efficiency.

In consideration of the above facts, the present invention aims to provide a film winder that can accommodate a plurality of films without joining them together, is easy to load into a developing device, etc., and can improve work efficiency. be.

[Means to solve the problem]

A film winder according to the present invention has a main shaft, and a plurality of take-up reels that are rotatable and rotatably supported around the main shaft and arranged around the main shaft. It is characterized in that the take-up reel is rotated on its own axis so as to send out the taken film, and also revolved so that the reel is positioned at a film winding position and a film delivery position.

[Effect]

According to the present invention, since the plurality of take-up reels are arranged around the main shaft, the take-up reels revolve around the main shaft as the main shaft rotates, and these take-up reels are sequentially positioned at the film winding position. be able to. The film can be wound up by rotating the take-up reel positioned at the film winding position. Therefore, the winding operation of the film is easy, and a plurality of films can be accommodated.

On the other hand, when taking out the film, it is possible to sequentially position the film to the film delivery position by revolution around the main axis.

The film can be fed out by rotating the take-up reel positioned at the film feeding position. Therefore, the work of taking out the film becomes easy.

In this way, multiple films can be wound independently onto a single film winder, so multiple films can be loaded into the loading slot of the developing and printing processing device at the same time without damaging the image surface. be able to. Furthermore, since the take-up reels are sequentially positioned at the film delivery position, there is no need to load each take-up reel, improving work efficiency.

〔Example〕

1 to 5 show a film winder 10 according to this embodiment. The outer shape of the film winder 10 is formed by a box-shaped casing 12. Inside the casing 12 are a plurality of (four in this embodiment) take-up reels 14.
is accommodated.

The outer diameter of each take-up reel 14 is such that the outermost circumference interferes between adjacent take-up reels 14 when viewed from the axial direction.

The flanges 16 of the take-up reel 14 are each formed with holding claws 18 that project inward.

This holding claw 18 has elastic force, and its protruding dimension gradually increases toward the tip. For this reason, when the film is wound up and stored, the negative film is pressed against both ends in the width direction and is elastically deformed, and when the negative film is completely wound up, it comes into contact with the outermost periphery of the negative film to prevent the winding from loosening. It has become.

Further, these take-up reels 14 are connected to adjacent take-up reels 1.
4 and are offset in the axial direction. Therefore, the structure is such that there is no interference during rotation about the respective rotational shafts 20. Note that when there are four take-up reels 14 as in this embodiment, there is no offset between a pair of take-up reels 14 that are point symmetrical to each other, and the other pair of take-up reels 14 are not offset. Just offset it. That is,
The rotating shaft 20 of one pair of take-up reels 14 has a shorter length in the axial direction, and the rotating shaft 20 of the other pair of take-up reels 14 has a shorter length in the axial direction.
is getting longer.

Each rotating shaft 20 has a length so as not to come into contact with the inner wall of the casing 12, and is pivotally supported at its tip by four tips of a substantially cross-shaped connecting bracket 22, respectively. A main shaft 24 is attached to the center of the connecting bracket 22, and is rotated by rotation of the main shaft 24.

Note that the main shaft 24 passes through a side wall 26 of the casing 12.

A planetary gear 28 is pivotally supported at the intermediate portion of each rotating shaft 20 that supports the take-up reel 14 . Although not shown, the planetary gear 28 is prevented from moving in the axial direction of the rotating shaft 20.

This planetary gear 28 is a sun gear 3 pivotally supported on the main shaft 24.
0 and mesh with each other. This planetary gear 28 has the role of a so-called flywheel, which prevents rattling when the take-up reel 14 rotates around the rotating shaft 20, and applies driving force to the rotation of the take-up reel 14. It is not something that is given.

Mutually opposite side walls 32.3 on the short side of the casing 12
4 are provided with rectangular through holes 36 and 38, respectively. One of the through holes 36 serves as an insertion port for a negative film (not shown), and the winding wheel 14 disposed near the through hole 36 allows the negative film to be wound up in layers.

Note that this through hole 36 is located above the side wall 32. A film guide bar 40 is inserted from the lower edge of the through hole 36.
has been extended.

At the upper inside of the casing 12, a shaft 44 is provided on the long side wall 26.42 corresponding to the through hole 36 serving as the insertion port.
A substantially V-shaped arm 46 is pivotally supported through the shaft, and is rotatable about a shaft 44 by the driving force of a drive unit (not shown).

An idle roller 48 is supported at one end of the arm 46 via a shaft (not shown), and a drive roller 50 is supported at the other end of the arm 46 via a shaft (not shown). The drive roller 50 is rotatable by the driving force of a drive section (not shown).

Here, when the arm 46 is rotated about the shaft 44 in the direction of the arrow in FIG.
The driving roller 50 is inserted between the flanges 16 of the flange 16, and the driving roller 50 is brought into contact with the peripheral edge of the flange 16. When the drive roller 50 rotates in this state, the take-up reel 14
The negative film rotates about the rotating shaft 20, and is guided by the idle roller 48 and wound up one after another.

Note that a pair of drive rollers 50 are provided, and one of the drive rollers 50 is brought into contact with the circumferential edge of the flange 16 of each offset take-up reel 14 .

The other through hole 38 is used as a negative film discharge port, and the negative film wound on the take-up reel 14 arranged near the through hole 38 is gradually unrolled and sequentially discharged from the through hole 38. It is supposed to be done. Note that this through hole 38 is located below the side wall 34.

Near the through hole 38 there is a shaft 52.54 to the side wall 26.42.
A peeling claw 56 and a driving roller arm 58 are respectively pivotally supported via the . A pair of drive rollers 60 are supported at the tip of the drive roller arm 58 via a shaft (not shown).
It is rotated by the driving force of a driving section (not shown). Here, when the drive roller 60 is rotated while being in contact with the flange 16 of the take-up reel 14, the outermost peripheral edge of the negative film is peeled off by the peeling claw 56, and the through hole 38
It is designed to guide you to.

The main shaft 24 passing through the side wall 26 of the casing 12 is connected, for example, to the rotating shaft of a pulse motor (not shown) provided at the most downstream side of the developing device, and is driven step by step every 90 degrees.

In addition, two through holes 36 are used as the t1 insertion port and discharge port.
．． The take-up reel 14 is successively positioned in the vicinity of 38.

The connection between the main shaft 24 and the pulse motor is removable, so that it can be removed from the developing device and connected to the most upstream pulse motor of the printing device.

The operation of this embodiment will be explained below.

The arm 46 is rotated about the shaft 44 in the direction of the arrow in FIG. 2, and the drive roller 50 is brought into contact with the peripheral end of the flange 16 of the take-up reel 14. As a result, the take-up reel 14 near the through hole 36 serving as the insertion port rotates. Here, when the leading end of the negative film is inserted into the through hole 36, the negative film is guided by the idle roller 48 and wound up into layers. When the rear end of the negative film is wound up, the outermost periphery including this rear end is held by the holding claws 18 that protrude inward from the flange 16, so that the winding is maintained without slack.

When winding of the negative film is completed, the arm 46 is rotated in the opposite direction to the arrow in FIG. 2, and the pulse motor is driven to rotate the main shaft 44 by 90 degrees. As a result, the connection bracket 22 rotates, and the empty take-up reel 14 is placed near the through hole 36. At this time, planetary gear 2
8 is driven by meshing with the sun gear 30, the winding wheel 14 revolves around the main shaft 24 without rattling.

By performing the above-described winding operation of the negative film onto each take-up reel 14 in this manner, the negative film is wound onto all four take-up reels 14.

After winding of the negative film onto all the take-up reels 14 is completed, the inner body of the winder 10 is moved along with the casing to another device, for example, from a developing device to a printing device.

Here, the drive roller arm 58 is rotated about the shaft 54, and the drive roller 60 is brought into contact with the peripheral end of the flange 160 of the take-up reel 14, which is disposed near the through hole 38, which serves as the discharge port. At the same time, the peeling claw 5G is made to correspond to the outermost periphery of the negative film being wound up on the winding wheel 14, and the driving roller 60 is rotated. As a result, the end of the negative film is peeled off by the peeling claw 56 and guided into the through hole 38. Thereby, the negative film can be discharged 111 times.

Each time the negative film wound on one take-up reel 14 is finished, the main shaft 24 is rotated 90 degrees by the drive of the pulse smoke, so that the four take-up reels 14 are sequentially moved through the through-holes. 38, and the negative film is pulled out.

In this way, negative films can be moved between different devices at the same time without having to join multiple negative films together, which saves the trouble of moving negative films, and also makes it easier to load each negative film into the device. Work is simplified and work efficiency is improved.

In addition, in this embodiment, the winding rule 1 is provided inside the casing 12.
Although four numbers 4 are provided, the number is not limited to this and may be increased or decreased.

In addition, the planetary gear 28 and the sun gear 30 are attached to the take-up reel 14.
This was applied to prevent rattling during revolution around the main shaft 1124 of When the sun gear 30 rotates, the planetary gears can rotate.
