Description

The film band that the receiving can of rail list is particularly useful for having exposed

Aspect the typesetting equipment of taking pictures, it is a kind of that to use the hot spot scanner unit of photosensitive rail belt material be known, rail belt material sends box from one can provide exposed portion, this transmission box is installed in the first boxlike receiving chamber, and along the rail belt material direction of transfer, in the back of exposed portion, a pair of derivation roll is set passes through exposed portion being used for transmitting rail belt material.Deriving the right back of roll, be provided with another boxlike receiving chamber that accepts box, the introducing of hot spot scanner unit and to derive roll right vertically is divided into the different sections (DE-C2-3318311) of a plurality of drivable or idle running along it.

It is out-of-date that the film carrier of present this rail belt material constitutes, because self tension force of rail belt material, corresponds to the Feeding speed of transfer system in the hot spot scanner unit, carries out the rolling of film.The hot spot scanner unit that forms like this can also pass through gear drive in addition, and the transmission synchronized movement of rail belt material is passed to another device.

In addition, there is not the coiling of reel core in the DD-PS0154852 patent specification, to disclose yet.In addition at US-PS4, also disclose in 299,458, in a kind of system of the flat rail belt material that crouches, rail belt material is wound in film holder on reel core.But this reel fuse by a garden tube and distribute on week in its garden a plurality ofly compress that pulley forms so that, can carry out the rolling of rail belt material when rotation garden tube and static when compressing pulley.

Here, be placed in the side that does not have light sensitive layer on the rail belt material owing to compress pulley, therefore usually, when rail belt material is when being made of exposed plate, its plane of exposure should be the inside face of rail belt material.

The common drawback of all known solutions is can only have short rail strip length to be stored in the film holder, so that the utilization of the hot spot scanner unit of capacity or its serial connection is very little certainly.Simultaneously when the production capacity hour, the exposing material that is consumed has just relatively increased, because unexposed being consumed of the appreciable rail belt material of length arranged.Therefore known film holder only has the little capacity of accepting, and this operating charges is big, therefore just suffers defeat on the high flow rate of exposing material.

The objective of the invention is to: realize that the rail belt material film holder has the capacity of acceptance can adapt in the capacity that sends, and should realize that full automaticity is loaded and the rolling of rail belt material, with the end of the fastening rail belt material of full automaticity and the rolling that adapts to different rail belt material width.

Advantage according to the present invention can reach especially is: can carry out full automaticity by the location of reel core and introduce (dress film) and rolling subsequently thereof, owing to can easily pack rail belt material in the fixing reference position of reel core.And only just anchor fitting can be disconnected by rail belt material.So can realize full automaticity dress volume and rolling, and the capacity of accepting is compared with known film holder and can be improved about 8-10 doubly.

In addition can, perhaps derive the driving of reel core from the hot spot scanner unit of serial connection, perhaps just be connected with the driving flange of receiving film holder; Therefore, driving can correspondingly be controlled.

Provided favourable enforcement structure of the present invention in the claim 2.In view of the above as can be known: the reel core is made up of first reel, half core and second reel, half core, and the turning cylinder rotation that first reel, half core can be provided with around the center, and second reel, half core is to captive joint with stub area, and always be connected on the rotating disk, rotating disk can center on single-piece center shaft (in sidewall) rotation.Can determine the position of reel core thus by the gravity of reel half core that rotates around turning cylinder.

According to remaining feature: rotating disk always is equiped with the gap in the garden on week for the engagement of anchor fitting, and outside center shaft, etcetera is set to the gap, in the garden approximately is relative position outside the center shaft on week, this mode has just produced rotating torque, the motion of following mode is provided, has made the reel core always rotate to the most desired position, in this case, the clamping gap ingate up so that the reel core always can be positioned the reference position definitely.

This principle realizes by following measures that easily the etcetera of the moment that rotates is made of a projection.Etcetera can be molded on rotating reel half core during fabrication.

Another improvement of the present invention is, the rotatable control pulley that is provided with uses as the anchor fitting on the lever, this pulley is when the reference position, be engaged in the gap, at this moment lever always is being provided with in sidewall rotationally, and interconnects along the center of turntable direction of principal axis, and the control pulley at first fixes two rotating disks in useful mode, above reel half core was rigidly fixed to, another reel half core was to settle rotationally.Reel first change after, cross its mutual connection, will control pulley by rail belt material self and put down, and disconnect the affixed of rotating disk thus, thereby and with the affixed also disconnection of two reel half cores.

The connection of bearing between the lever of controlling pulley is made of the guiding arch, and rail belt material (after first commentaries on classics) when beginning to adorn film and in winding process is close on the arch.Such formation is useful.

Make film holder and mainly simplified by following measure, that is: the reel core is made up of two identical reel half cores of shape.Such manufacturing technology only needs unique a kind of die casting instrument.

Another kind of structure of the present invention is: the clamping gap inlet hole is by falling the garden on reel half core, and a corresponding slope realizes and constitute on another reel half core.Here also can use the principle of unique die casting instrument, these two reel half cores are relatively placed with its inside face, occur twice on week so that corresponding clamping gap enters Kong Zaiyuan.

For the rail list, when for example constituting, form a clamping gap between two reel half cores by film stock, its size is favourable between the 0.1-0.5 millimeter.

Another advantage is, when providing to the hot spot scanner unit when sending box and accepting the box operation, derives to the reel core, comes the propulsive effort of self-driven hot spot scanner unit, is unnecessary so that connect second motor with flange.Therefore exactly, it is just much of that hot spot scanner unit and reel core only need have a CD-ROM drive motor.

Also have other advantage to be: a slope shape guide rail being set after slit entrance, having a hold-down roller to be positioned at the opposite, and keep a slit spacing, along the transmission direction of domatic guide rail, and then is thereafter an axis of guide, is arranged between the side wall of outer shell.Guide rail and hold-down roller can prevent that not only light from invading exposed film and accepting box, and can mechanically clamp the initiating terminal of rail belt material, and the initiating terminal that allows rail belt material for example when film winding operation, easily imports film in the developing apparatus again when continuing to add man-hour.

Embodiments of the invention and are described in detail as follows as shown in FIG.:

Fig. 1 is that the film that has preposition optical scanner is accepted the box section-drawing,

Fig. 2 is the part that has a reel core of the anchor fitting cross sectional drawing that stretches tight.

Fig. 3 is illustrated in the section-drawing at place, demarcation line between left-hand rotation dish and the reel core, comprises control pulley and movable guiding arch.

Fig. 4 is illustrated in the section-drawing at place, demarcation line between left-hand rotation dish and the reel core, as seen has the rotating disk of controlling pulley.

Fig. 5 represents two reel half cores, represents with the section that amplifies.

Rail belt material 1(is the film band for example) 2a is entered in the receiving can with shell 13 along throughput direction 24 by driving roll from hot spot scanner unit 2.Rail belt material 1 guides and at first gives bending or enters in the reel core 5 in adjacent mode through movable guiding arch 4 under the internal stress effect at track adjusting wheel 3 places.Reel core 5 is made up of first reel, half core 5a and second reel, half core 5b.Two reel

half core

5a and 5b constitute clamping gap 14, and it is at reference position 15(Fig. 3 and Fig. 5) time, clamping gap inlet port 16 points to.At reel core end region 17(Fig. 2) located anchor fitting 18, it is made up of control pulley 6 at that time in an embodiment, control pulley 6 is under 15 situations of reference position, before the initiating terminal with rail belt material penetrates at that time gap 10, rabbeted by rotating disk 9, therefore fix this reference position, reel core 5 is not driven when this position, in other words, reel core transfixion when its reference position 15.

When this position (Fig. 1), roll passes through slit entrance 13a to 2a with rail belt material 1, between the guide rail 8 and hold-down roller 7 of slope shape, enter the inside 13b of shell 13 after passing, the initiating terminal of rail belt material or enter clamping gap inlet port 16 by himself tension force or by movable guiding arch 4, arrive the position shown in 26 among the figure, the movable property in this position 26 owing to reel half core 5a just in time is pressed on the clamping point 27 always.Equally, rail belt material 1 is clamped at clamping point 28 places.According to the configuration of clamping gap inlet port 16, rail belt material 1 also just in time relies on clamping point 29 places.According to Fig. 5, the version of reel core 5 tightens up face 30 in addition except

fastening point

27 and 28 are arranged.

By the CD-ROM drive motor (not expressing among the figure) of light-spot scanner 2, after throughput direction 24 rotations, reel core 5 rotates.Fixing reel half core 5b always is rigidly fixed on the reel core end region 17 by means of fastener 25; During this period, movable reel half core 5a is around steering shaft 12 rotations, and by reel half core 5a, the unit that 5b and rotating disk 9 are formed rotates twelve Earthly Branches by means of pivot bearing 9c around S. A. 9b and holding in sidewall 13d.The garden week 9a of rotating disk 9 is provided with an etcetera 11, is cam face.Cam 11a(Fig. 3) produces a dextrorotary torque and reel half core 5a produces the torque of an anti-clockwise rotation around steering shaft 12, so that also can guarantee grip rails carrying material 1 when pulley 6 is removed when controlling.Can be by the unit that rotating disk 9 and reel

half core

5a and 5b form around center shaft 19 rotations.

When CD-ROM drive motor begins to rotate reel core 5 by rotating disk 9, not only rail belt material 1 is produced further and clamp, and in next process (Fig. 2) guiding arch 4 or bearing control pulley 6 lever 20 between another connection, be removed by rail belt material 1, lever is installed in the bearing shell of two side 13d, rotate around lever S. A. 21, consequently controlling pulley 6 is shifted out (Fig. 4) from its gap 10.Then reel core 5 can synchronously rotate driving together with roll to the motion of 2a, and rail belt material 1 winds up with bigger length.

Reel core 5 according to Fig. 5 is to make identical reel

half core

5a and 5b by 2 to constitute, and entering 16 places, hole at clamping gap always has garden 22, and a slope 23 is arranged over there.On the clamping surface 30 between reel half core 5a and the 5b, for the film band, the value of clamping gap 14 is greatly about the 0.1-0.5mm order of magnitude.

The exposing material that is rolled into, it reacts on the energy (effect of torsion spring) of reel core CD-ROM drive motor and produces therefrom, the pulling force that acts on the point 29 of movable reel half core 5a is kept by reverse motion blocking mechanism, and this pulling force is essential for fastening rail belt material initiating terminal.Like this, under various working conditions, can access coiling of a fastening stable rail belt material.The control that the coiling that is fastenedly connected with hot spot scanner unit 2 drives realizes by the hot spot scanner unit.

Receiving can drives to connect by inserting receiving can to the coiling of light-spot scanner 2 and realizes automatically, and is preferably to have adopted (not detail display) gear drive in an embodiment.Its side has a coast at least, so that automatically guarantee the interlock of gear.

Cut off after the rail belt material 1 with cutter sweep on light-spot scanner, then the end of this rail belt material is fixing by compressing running roller 7.In addition, compress running roller 7 and be pressed on the slope track 8, can also stop the intrusion of external light.

After the reel core 5 rotation first laps, guiding arch 4 just raises by the rail belt material 1 of reeling, so that control pulley 6 shifts out the gap 10 in rotating disk 9, and therefore reel core 5 can drop into receiving can and reach out rail belt material in the developing apparatus along all removing interlocking on two hand of rotation.
