Description

APPARATUS AND METHODS OF CAMERA ASSEMBLY DESCRIPTION OF THE INVENTION: Reference is made to U.S. patent application Ser. copendiente assigned in common no. of series 08 / 840,482 titled METHODS OF ASSEMBLY OF CHAMBER AND APPLIANCES, filed on April 21, 1997, in the name of Watkins. Reference is made to U.S. patent application Ser. copendiente assigned in common no. series 08 / 837,632 entitled METHOD AND APPARATUS FOR LOADING A CARTRIDGE IN A CAMERA FRAME ASSEMBLY, filed on April 21, 1997 on behalf of Marra et al. Reference is made to U.S. patent application Ser. copendiente assigned in common. Serial no. titled APPARATUS FOR THE RECOLLATION OF A REEL TO ASSEMBLE A CHAMBER AND METHODS, presented concurrently with this application on behalf of. Reference is made to U.S. patent application Ser. copendiente assigned in common. Serial No. titled APPARATUS AND METHODS TO LOAD A CARTRIDGE filed concurrently with this application on behalf of. The invention relates to photographic equipment and more particularly relates to methods and apparatus for assembling cameras. Single-use or disposable cameras are usually sold pre-loaded with a roll of film. In order to reduce complexity and costs, a winding mechanism in the camera is omitted. It is time that the film is already extended and during the use it advances returning to the film reel. Several proposals have been followed for the loading and pre-winding of film rolls for use in single-use cameras. In some propositions, such as the one taught in U.S. Patent 4,972,649, the film is precoiled in a roll out of the body of the chamber and then loaded. A disadvantage of these variants is that the film roll must be handled after it has been formed. This presents the risk of damage to the film and can add complexity to the necessary equipment. In some propositions also taught in U.S. Patent 4,972,649, the cartridge is charged, the chamber is hermetically closed to light, and then the film is pre-coiled. In other proposals such as the one taught in US Pat. No. 5,311,231, the cartridge is loaded and the rear opening of the chamber body is closed and the film is prewired through an opening in the floor, which is subsequently sealed. The last two variants have the disadvantage that the film guide is provided by the body of the camera, rather than a charging apparatus. This establishes limitations on the body of the camera in terms of the required tolerance and the like and can also slow down the passing speeds. Another variant is taught in Japanese Patent 6- 295022, European Patent Application No. 0743546-A, and Japanese Patent 8-171180. In this variant, the film is wound on a second reel, rather than on a roll of film. The back of the camera is not important to guide the film, since the second reel tends to compress the film. One of the risks presented in the loading and pre-winding cartridges in the single-use chamber assemblies is the damage from perforation of the film strip during assembly. In variations such as that taught in U.S. Patent 5,311,231 perforation can result from a telescoping of the film roll after pre-winding. Thus it would be desirable to provide chamber assembly methods and also apparatus in which a film without reel is wound, from a cartridge, into an open chamber assembly, using the components of the apparatus as a guide for the winding and reducing the risk of perforation and pinching of the film strip, including pinching due to telescoping out of the film roll. The invention is defined in the claims. The invention in its broadest aspect, provides a method and apparatus for assembling a photographic camera having a cartridge chamber and a film camera, the film cartridge includes a spool and a film strip. A front portion of the film strip is crimped around an internal crimping axis in the supplementary chamber. During crimping, the deflection of the leading portion in the radial directions to the axis beyond a predetermined preliminary radius is limited. A main portion of the film strip is wound around the front portion to form a roll of film. This has a turn that is the outermost and defines a first radius of film roll greater than the preliminary radius. After winding, the film roll is allowed to expand to a second film roll radius greater than the first film roll radius, the telescopy being limited out of the film roll. It is an advantageous effect of at least some of the embodiments of the invention that assembly methods and apparatus are provided wherein a roll of film without reel is wound, from a cartridge, into an open chamber assembly, using components of the apparatus for guide and reduce the risk of pinching of the film strip, including pinching due to the external telescoping of the film roll.

In the apparatus and method of the invention, a film is prewound in a camera frame assembly 10, that is, a camera or an incomplete camera sub-unit, in a dark room. The chamber frame assembly 10 includes a chamber frame 12 having a cartridge chamber 14 and a supply chamber or snail chamber 16. The cartridge and supply chambers 14, 16 each have a throat or opening facing rearwardly. , 17, respectively. The supply chamber 16 has one or two lateral openings 18 which are continued from the throat 17. The chamber frame 12 has an intermediate section or exposure frame 20 between the chambers 14, 16, the supply chamber 16 has an interior wall concave 22 defining an internal, essentially cylindrical, film space 24 having a film space axis 26. The frame assembly 10 lacks film spool or other axial support for the film, thus the film space 24 is empty , and remains empty except for the film roll. The frame assembly 10 defines a rear opening or rear access (indicated by the interrupted line 28 in Figure 2) on the supply chamber and preferably on both chambers 14, 16 and the intermediate section 20. The film cartridge 30 loaded inside of the frame assembly 10 includes a reservoir 32, a reel 34, a film strip 36. The film strip 36 has a front portion 38 having a free end 40, a tail portion 42, which is attached to the reel 34 in the tank 32, and a main portion 44 between the front and rear portions 38, 42. The camera frame assembly may also include other camera components that have been previously installed in the frame of the chamber. For example, the camera frame assembly 10 may include an exposure system 46, including one or more sub-components such as a baffle, a lens system, and a shutter. The frame assembly 10 may include a film driver 48 having a film engaging member (indicated diagrammatically in Figure 2 by a semicircle 50) that attaches to the intermediate section 20 and engages the perforations of the film. (not shown) to measure the film or both for measurement and transport of the film. A variety of such camera film impellers are well known to the technicians, in such impellers the film coupling member can be a pawl of reciprocal linear movement; however, a toothed wheel is more commonly used as a coupling member with the film. In many film impellers for type 135 (35 mm) the cogwheel is a series of continuous teeth. The sprocket rotates with film movement but at all times, part of the cogwheel extends rearward from the middle section. In some APS-type film impellers, the film engaging member is a skate or an incompletely cogwheel where an oval wheel has a pair of teeth at the end of its longest axis and a portion without teeth at each end of its shorter axis, with some film transport mechanisms, such as types of skates, the film can move past the skate or other coupling member without causing it to rotate or otherwise operate, the apparatus and method, in different modalities , can accommodate any type of film transport mechanism. The apparatus 52 includes a receiver 54, and active components 56 for loading the cartridge, transporting the film and winding the same, the method will be explained in relation to those components. The method is particularly suitable for winding the film in single-use cameras, but it is also suitable for winding film in reusable cameras sold ready-to-use, that is, with the film cartridge already loaded and pre-wound. a film cartridge 30 is loaded into the cartridge chamber 14 of a camera frame assembly 10; and a film strip 36, attached at one end to the reel 34 in the cartridge 30, is wound in a roll of film 62 in the other film chamber 16. After the winding of the film, the film strip 36 extends from the cartridge 30, on the intermediate section 20 to the supply chamber 16, and the main portion 44 of the film strip is a roll of film 62 that rests in the supply chamber 16. The method begins with the provision of the assemblies of chamber frame 10. These assemblies can be manufactured as a part of a continuous process with the method or they can be manufactured in an independent process. The camera frame assemblies 10, prepared in some way, are placed in the container 54 of the apparatus 52. The receiver 54 supports the camera frame assembly 10 in a predetermined loading position 10a or series of positions 10a with respect to the components 56 of the device 52. The receiver 54 has a predetermined relationship with the other components 56, and thus during assembly, defines a relative predetermined location for each of the chambers, grooves, intermediate section, film space, and back opening. (the sites correspond to characteristics of the frame assembly and are necessarily predetermined for a particular frame assembly when adjusting to physical constraints such as the relative positions of the receiver and other components of the apparatus In Figure 4, representative places or sites are indicated in interrupted lines and by reference figures identical to those of similar characteristics of the assembly, but adding the letter "a"). The receiver 54 can accept the camera assembly 10 directly or it can be adapted to accept a paddle or nest 64 or the like. In that case, the camera frame assembly 10 is stopped in a predetermined relation to the paddle or nest 64, which in turn will be stopped in a load orientation predetermined by the receiver 54. the characteristics of giving index 65 can provided on the pallet to allow the camera frame assembly 10 and receiver 54 to be easily aligned. The frame assembly 10 can be provided to the receiver 54, already preassembled on a pallet or the pallet and frame assembly can be combined on the receiver. The receiver 54 may have a variety of features to support automated assembly operations. For example, the apparatus may include a setter or positioner, indicated schematically in Figure 1 by the positioner 66, to move a camera frame assembly 10 between the apparatus and one or more assembly stations or between stations having different components of the apparatus. apparatus. It is convenient, that the following discussion is directed directly to an apparatus 52, such as the one shown schematically in Figure 5, where the components 56 are divided among a series of different stations 68 and the receiver 54 is a system in movement that transports the assembly of frame 10 from station to station. The apparatus components 56 may each include an actuation mechanism 70. The mechanisms 70 may include an extension retraction system for moving the respective components between a non-use position 72, in which the component is separated from the receiver, and a use or active position 74. The actuation mechanism can also include other parts to impart movement to the components, such as rotary or linear drives. After the frame assembly 10 has been placed in the receiver 54, a film cartridge 30 is placed in the cartridge chamber 14 of the frame assembly 10 and the film strip is advanced through the intermediate section 20. Referring now to a mode shown in Figure 6, the apparatus 52 includes a cartridge mover 76 for positioning the cartridge 30 in the cartridge chamber 14. The cartridge is placed in alignment with the axis of the cartridge chamber 15, ie the long dimension of the cartridge and the shaft of the cartridge reel are aligned with the long dimension of the cartridge chamber. It is desirable that the cartridge chamber follow the ordinary practice in the manufacture of cameras and have a size that allows or provides for the placement of a cartridge within the cartridge chamber in non-alignment with the cartridge chamber axis 15. The cartridge also it is placed next to the butterfly wheel in an axial proximity. It is highly desirable that the axial proximity be very large, that is, that a small fraction of the length of the cartridge chamber is remote from the thumbwheel, since the more distant there is the risk of the cartridge oscillating away from the Camera axis when the cartridge is subsequently moved towards the butterfly wheel. The cartridge mover 76, has a vacuum gripper 78, which allows the cartridge mover 76, place the cartridge 30, in the cartridge chamber 14, and optionally continue to grip or press the cartridge 30, during the winding of the film. The cartridge 30 can be released after the film winding is completed. That is convenient, if the assembly 10 of the camera structure lacks means to prevent oscillation or other movement of the cartridge 30, during winding of the film. The cartridge mover 76 can support other components such as an opener 80, active light blocking and a spool rotator 82. The active light block opener 80 is pivoted to open the active light closure of a film cartridge suitable, such as an Advanced Photo System cartridge (registered trademark), before placing the cartridge in the camera seat. This allows the camera frame assembly to include a retainer (not shown), which retains the active light lock in the open position during the use of the film. The spool rotator 82 engages the spool 34 of the cartridge 30 and rotates the cartridge 84 to push the film strip 36 from the cartridge 30. Referring now to FIGS. 1 and 7, in some embodiments a film bridge 86, is then moved with respect to the frame assembly 10, to an active position on the intermediate section 20, of the frame assembly. This can be done in the same station 68, or the frame assembly 10, can be moved to a new station 68, which includes a film bridge 68. The film bridge 86, defines a film path 88, which extends from the cartridge chamber 14, to the supply chamber 16. (In Figs 1 and 7 the film path 88 is occupied by the film strip 36). In embodiments in which the frame assembly 10 has a film engaging member 50, such as a conventional crown, which continuously extends outwardly from the intermediate section 20, it will be preferred that the trajectory 88 be spaced from the seat of the frame. intermediate section 20a, since this separates strip 36, from the chamber film drive, whereby it does not need to be disarmed during the formation of the film roll. Within these limitations, the film bridge 86 can take several forms. For example, the film bridge 86 may be like the turtle back shown in Fig. 7, it is preferred that the turtle back exhibits minimal friction to the film strip. The turtle back may have one or more friction reduction characteristics (indicated by the figure 87, in Fig. 7); such as holes and a connection with pressurized gas for an air cushion or rotating bearings. It is greatly preferred that the film bridge 86 includes a film transport arranged in a functional relationship to the path 88 to drive the film strip along its path to the supply chamber. Examples of film bridges including a film transport include a winch impeller, a vacuum agitator, such as that presented in US Patent 5,125,630, and an endless band mechanism. The endless band may be disposed between the film strip and the section 20 of the camera frame assembly or as shown in Fig. 1, it may cover the film strip 36. In this case, the band mechanism without end can have holes (not shown), and includes a vacuum-compressed gas unit 89, to provide a vacuum and pull the film strip against the web 90, for transport and compressed gas directly against the strip 36, to release it of the band 90. The mechanism includes a band impeller 91, and idler gear rollers 92, which give position and tension to the band 90.

Figs. 8-12, illustrate alternative embodiments of the apparatus that is used with a frame assembly 10b, including a butterfly wheel 94, which is mounted on an end wall 96, of the cartridge chamber 14, the wheel 94, is attached to the frame 12, and thus can rotate with respect to the frame 12. The butterfly wheel 94, has a rotation member 98, which in the finished chamber is rotated to advance the film. The wheel 94 has an axially positioned drive key 100, which extends within the space 14b, of the cartridge chamber. A collar or an elastic flange (not shown) stops the wheel 94, instead in the frame 12. The drive key 100, is complementary in shape to an axial cut or coupling portion 102, of the spool, either of a standard film cartridge or cartridge with a specially shaped cut for use in a specific camera. For use with APS film, the drive key 100, has the shape shown in Fig. 9, and can match the cut 102, of the reel 84, in only a single orientation. Referring now to Figs. 5 and 8, in a first station 68, a camera frame assembly is placed on a pallet 64, by a suitable component 56, such as a pick-and-place device. Referring to Fig. 8, in the same or in a second station 68, a first cartridge mover 76, such as a vacuum gripper grasps an APS cartridge, or the like from a storage (not shown) and places the cartridge 30, within a nest 103, in the pallet 64. While the cartridge 30, an active light block opener is grasped (shown for a different embodiment in Fig. 6), it engages and rotates the active light block 90 degrees to open completely the film exit of the cartridge 30. In the embodiment of Fig. 6, the active lightweight opener 80, is illustrated as sharing a common support with the vacuum gripper 76, however, it is to be understood that this and other components 56, of the apparatus 52, can be mounted separately or commonly in a wide variety of ways, in the discussed embodiment, the components of the apparatus 56, are retracted from the frame assembly 10, and the blade 64, moves on the 64, a the next station 68. Referring to as Figs. 5, 8 and 9, in the same station 68, or in a third station 68, the same or a second cartridge mover 76, takes the cartridge 30, and places it in the cartridge chamber 14, in a tight axial proximity to the drive key 100, of the butterfly wheel 94. The cartridge 30, does not move as much within the space 14b, as for coupling the cut 102, of the cartridge reel 84, and the drive key 100. The reason is because A film cartridge such as an APS cartridge, when the cartridge door is opened, the film reel is unlocked. Thus, the coupling portion 102, and the drive key 100, may be misaligned and it is undesirable to force the parts that come together.

The cartridge mover 76 is removed and the frame assembly 10b moves to the next station 68. Referring to Figs. 9-10, in the same station or a fourth station a sleeve 104, is moved by a linear actuator 106, in an axial direction (indicated by the arrow 108), with respect to the spool 84, of the cartridge 30. The sleeve 104 , has a drive key 110, is complementary in shape to a second cut or coupling 112, (indicated by interrupted lines in Fig. 9), of the spool 84. The cuts 102, 112, on opposite ends of the cartridge reel 84 , can have an equal or different shape, a tap member 114 moves, as indicated in the Fig. by a double-headed arrow 116, from a non-use position spaced from the supply chamber seat 14a, to a position of use wherein the staple making member 114 abuts against the butterfly wheel 98, embracing the wheel 98, and preventing rotation thereof with respect to the frame 12. A light axial load (supplied by the action 106), in the sleeve 104, forcing it against the spool 84, and the spool 84, against the key 100, of the butterfly wheel 94. At the same time, the sleeve 104, rotated by the drive device 70, backwards ( indicated by arrow 106), this is sleeve 104, rotated in a direction of rotation that when applied to the cartridge will pull and extend the film strip back or back into the cartridge. This is the rewinding direction for the film cartridge or the direction in which the spool rotates to rewind the film in the cartridge. With a film cartridge of the push type, this direction is also opposite to the thrust of the film, the rotation of the sleeve 104, causes that first one and then another of the keys 100, 110, and the respective cuts 102, 112, align with two revolutions of the sleeve 104, when the first cut 102, of the spool 84, and the key 100, are aligned, the cartridge 30, moves axially (generally in the direction indicated by the arrow 108), under the force applied by the sleeve 104, with respect to the axes common to the thumbwheel and cartridge, 116, 118, until the first cut 102 has moved to match the key 100, and the cartridge is seated against the wheel 94, and the end wall 96. Similarly, when the second cut 112, of the spool 84, and the key 110, of the sleeve are aligned, the key 110, moves axially within the second cut 112. The drive key 110, of the sleeve 104 , can be mounted in spring to moderate the force applied by the sleeve 104, and prevent some alteration during the movement of the sleeve before the engagement of both cutting pairs 102, 112, and of the drive keys 100, 110. After the cartridge has been seated, the grip member it is removed from the thumb wheel, the spring load can only be axial or provide elasticity in the axial direction and in another direction to correct possible misalignment of the sleeve and the axes of the cartridge and the thumbwheel. In a particular embodiment, the second spool cut 112 is circular or similarly radially symmetrical except for a radial recess 109. In that embodiment, the drive key 110 of the sleeve includes a retainer 111, which is configured to fit into a recess 109. The key member 111 is movable independently of the body 113 of the key 100, in the directions (indicated by the arrow 115), basically radial to the axis of rotation of the sleeve and is elastically guided outwards, the key member 111 , allows the sleeve key to enter the cut 112, even if it is radially misaligned. The key 110 can rotate within the cut 112, until the key member 111, is aligned and elastically moves within the cut 112. The discussion is basically directed to a mode using an APS cartridge, however, this procedure is applicable both to push-type film cartridges, such as APS cartridges, and to cartridges of a non-push type, such as the type of cartridges 135. In this case, care must be taken to avoid removal of the entire guide to the cartridge during the seat of the same. A detector 120 can be mounted in operative relation to the cartridge chamber space 14a to sense the axial movement of the cartridge 30. The detector 120 can be integrated into a control system that can stop the operation and retain the sleeve if detects a condition with failure. Referring to Figs. 11-13, the sleeve is then driven by a motor or drive mechanism 70, in a forward direction (indicated by arrow 122), rotating the cartridge spool and pushing a leader portion 38, of the film strip 36, from the cartridge 30. This can be done more conveniently in the same assembly station that was used to put the cartridge. The thrust of the film can be continued until the free end 40, from strip 36, be taken to the supply chamber. A detector 124 may be positioned to sense optically or in another manner when it reaches the free end 40, the space 16a, of the supply chamber and signal the controller (not shown) to stop the thrust. >; In a particular embodiment, the structure or frame assembly has fingers 126, for film retention as presented in the US application 08 / 796,155, entitled "CAMERA FOR USE ONCE YOU HAVE A PART OF MAIN BODY AND A LIGHT SHOCK ABSORBER INSERTING WITH FILM RETAINERS TO FACILITATE THE CAMERA ASSEMBLY ", presented on February 6, 1997, by Douglas H. Pearson, which is incorporated by reference. The film retaining fingers 126 define a film inlet 128, which leads to the space 16a, of the supply chamber. In this embodiment, a film guide member 130 directs the free end 40, of the film strip 36, through the film inlet 128, and into the interior of the space 16a. The member 130 is lowered from position on the intermediate section 20 of the frame assembly 10 by a linear actuator 106, before or during the thrust of the film, in the same station that was used for the cartridge seat or in another rear station (as shown in Fig. 12). The film guide member 130, has a concave bottom 132, which lies above the intermediate section 20, the film member 130, has pockets 134, which receive * the film retaining fingers 126, so that the entry of film 128, defined by the film members 126, remain in an ellipse defined by the concave bottom 132, of the guide member 130. The detector 124 can conveniently be accommodated in the guide member 130. Referring to Figs. 14-20 , after the free end 40, of the portion 38, of the film strip 36, has advanced to the supply chamber 16, the frame assembly 10, moves to another station 68. In this station a mandrel or spool 136, attached to the apparatus 52, is introduced into the chamber 16, together with one or preferably a plurality of film guides 138. These define a preliminarily cylindrical film space 140, within the supply chamber 16, centered on the mandrel 136. The space io of preliminary film 140, has a radius 142, (hereinafter referred to as preliminary radius 142), which is predetermined by the internal configuration of the film guides 138, that portion of the film strip 36, is transported to the film space preliminary 140, and is curled around the mandrel 136, and a curling shaft (indicated by a cross 144), in Fig. 14. The shaft 144, is disposed within the chamber 116, and is at the coextensive ripple time with the axis of rotation of the mandrel. The guides 138 are interposed between the inner wall 146, the supply chamber 16, and the mandrel 136, and both guide the portion 138, of the strip 36, around the mandrel 136, and the limit deflection of the film strip 36, in radial directions to the common axis of rotation of the mandrel and the curling shaft 144. The initial return (not shown separately), of the film strip 36, is cinched to the mandrel. 136, guides 138, are retracted from the supply chamber (in preferred embodiments) currently in a direction parallel to the axis of curling and most of the film strip 36, is wound around the initial turn to form a roll of film 62, shown in Figs. 2 and 3. The mandrel 136 is preferably a vacuum mandrel, that is, a hollow cylinder pierced on the longitudinal surface by air passages 148, and is connected to a vacuum pump or negative air pressure source (not shown). ). When the leading portion 38, of the strip 36, curls around the mandrel 136, the vacuum forces the strip 36, in contact with the mandrel 136. The mandrel 136 rotates about the axis of the mandrel 150, beginning before or after the free end 40, of the film strip 36, makes contact with the mandrel 136, and the guide portion 38, of the film strip 36, overlaps and cinches against the mandrel 136, after which the main portion 44, from the film strip 36, it is wound on the first turn of the film roll. Referring particularly to Figs. 14-15, the guide or guides 138 can be relatively simple, for example, as shown in Figs. 14-15, a first cinching pawl 152 has a hooked cross-section that can be used. The cinching pawl 152 is placed in the supply chamber 16, with the rod 154, towards the distal side 155, and the opening of the hook 156, opposite the direction of entry of the film strip 36, into the chamber supply 16. After the film strip is cinched, the web pawl 52 is withdrawn in an axial direction from the film chamber 16. In this embodiment, the mandrel 136 can be lowered into the supply chamber 16. , during the winding of the film (in the direction indicated by the arrow 158 from an alternative axis of curling indicated by a cross with circle 160), in order to continue maintaining the contact or tangency between the vertex or outermost turn of the film roll and the film inlet 128, or the downstream end of the film bridge 86, to bring to a minimum the force applied to the film strip 36, during winding. Thus, in this embodiment the axis of rotation of the mandrel 136, moves away from the axis 160, during the winding and sinks into the supply chamber 16. Referring to Figs. 16-20, in preferred embodiments, a set of multiple guides 138 is used. The multiple guides surround the mandrel 136, in radial directions to the mandrel shaft 150, except for an inlet 162, through which the strip of the mandrel is admitted. movie. In these embodiments, the guides 138, prevent the leading portion 38, of the strip 36, from deflecting in radial directions to the axis 150, beyond a preliminary radius 142, which defines the boundaries of the preliminary film space 140, the portion 48 of the strip 36, is thus isolated from the inner wall 146, of the supply chamber 16, as the leader portion 38, is crimped and cinched around the mandrel 136. The axis of the mandrel 150, and the preliminary axis of the movie space, they are coextensive. The mandrel 136 can be lowered into the supply chamber 16 during winding of the film to maintain the tangency between the outermost turn of the film roll and the section of the film strip 36, which penetrates the camera 16, film supply. In particular embodiments, the structure or frame 12 has film retention fingers 126, and the mandrel 136 is retained in a central position within the supply chamber 16 during winding of the film. This latter design has the advantage of requiring simpler equipment to move the mandrel 136, in a particular embodiment shown in Figs. 16-20, in which the mandrel 136, is held in a fixed position, the mandrel 136, the film space and the film supply chamber 16, have a common axis 150. In this embodiment, the assembly of the guides 138, includes detachable upper and lower guides 164, 166, respectively. It is preferred that the guide 166, be a partially arcuate sleeve having a C-shaped cross-section, that sleeve 166, has a concave surface 168, which is smooth or otherwise configured to present low friction to the film strip. The inner surface 168 of the partial sleeve 166 is almost attached to the mandrel 136. In a particular embodiment, the spacing is a few times the thickness of the film strip 36, about 1 mm. The partial sleeve 166 is coaxial or almost coaxial with the mandrel 136, and extends around more than half (this is more than 180 degrees), of interposed mandrel 136. The lower guide 166 has a distal edge 170, which it is at least coarsely parallel to the axis of the mandrel 150, and has a horizontal diameter of mandrel 136. The lower guide 166 has a central edge 172, coarsely parallel to the axis 150, and an imaginary line tangent to the mandrel 136. (The terms horizontal and vertical and the like are used here in a relative sense where the longer dimension of the structural assembly defines a horizontal direction the actual orientations can be varied as desired, taking into account the effect of gravity on the loose parts). It is preferred that the upper guide 134, is a guide shoe that is movable independently of the partial sleeve 166. The shoe 164 has an arm 164, which extends downwards and makes contact with the distant edge 170, of the partial sleeve 166. The arm 164 may be continuous or divided into two discontinuous parts as shown in Figs. 16-20. The arm 164 has a low friction concave inner surface 176. The arm 164 has a lower edge 178, which meets the distal edge 170, of the partial sleeve 166, to present a guide path to the film strip that be basically free of discontinuity. The lower end 178 and the distant edge 170 may be found to provide a continuous curve interrupted only by a narrow seam. Alternatively the lower edge 168, may extend radially inward beyond the distant edge 170, to define a guide path for the film strip in which that strip jumps the discontinuity between the edges 78, 170, the latter design has the advantage that small misalignments do not present the risk of chiseling the film strip. The guide shoe 164, has a support member 180, central (to the left in Fig. 20), with respect to arm 164, of the guide shoe. The support member 180, is positioned to thereby separate from the mandrel 136, by a small space 182, when the upper and lower guides 164, 166, are in operative position within the supply chamber 16, and the film strip 36, it is positioned between the mandrel 136, and the support member 180. The support member 180 can be mounted in a compressible or elastic manner, so that the space 182 is at least partially a function of the deflection of the support member during the use or the support member may be a rigidly assembled incompressible part. The support member 180 may be a slide or bushing through which the film strip passes. The support member 180 may also be a rotating member such as a driven roller or band or the like, which rotates the same or at different speeds than the mandrel. There are disadvantages in the drive of the support member, however, since relative differences in the speed of the film and the support member represent a risk of damaging or abrading the film strip. It is thus preferred that the support member be a non-energized rotating member, such as a idler roller 180 that rotates freely with the passage of the film wrath and has a low friction load on the film strip. For the same reason, it is meant that the idler roller 180 rotates about an axis parallel to the axis of the mandrel 150. The width of the support member 180 in a direction parallel to the axis of the mandrel 150 is not critical, however, a member of Relatively narrow support presents less spatial constraints for the other components of the apparatus, the anchoring equipment and the like. A suitable width for the support member 180 is less than about half the width of the film strip. In the embodiment of Figures 16-20, the support member or idler 180 has a width that is approximately one quarter the width of the film strip 36. The idler roller 180 may have a flange (not shown extending to The fin can help maintain the alignment of the film strip guide and the mandrel by limiting both the lateral and torsional movement of the film strip around its longitudinal axis. The flange may be superfluous if the front end of the feed bed is closed.The guide shoe 164 includes a support portion 184 that provides physical support to the arm 174 and the support member 180. For example, the support portion in FIGS. 20, carries the axis of the support member 180. The support portion 184 is preferably configured to avoid any possibility of accidental contact with the film strip, as shown in FIG. to 20, in particular embodiments of the support portion 184 may be attached to another component 56 such as a film bridge or a film guide member as a single unit. The assembly of the guides can include a separator 186. The spacer 186 has a shoulder 188 (as seen less in FIG. 18) defining a lateral limit for the film roll, the spacer 186 may have a dimension in radial direction to a spacer axis, which is smaller, equal or greater to the dimensions of the feeding chamber in the same direction. In a particular embodiment, the separator 186 is a complete sleeve that is coaxial with the mandrel 136 and is separated from the mandrel 136 by means of the thickness of the film strip 36 and preferably about half the thickness of the film strip. In this embodiment, the dimensions of spacer 186 in radial directions to the spacer shaft (which is coextensive with mandrel shaft 150), are smaller than the dimensions of preliminary film space 140 in the same direction and partial sleeve 164 is coaxial to the separator 186. This allows the mandrel 136, the partial sleeve 164, and the separator 186 to move along the common axis, independent of its and without interfering; and at the same time it keeps the dimensions of the appliance in general and of the feeding chamber reduced. In the mode shown in Figures 16-20, the guide assembly is used as follows. The guide portion 40 of the film strip 36 is advanced to the supply chamber 16 until the free end 40 is detected by a sensor (not illustrated in those figures) that can be mounted on the guide shoe 164. The separator 186 is then moves by means of a linear actuator 106 to the feed chamber until the shoulder 188 of the separate 186 contacts the edge of the film strip 36. The separator 186 then stops. The partial sleeve 166 then moves along the separator 186 and into the supply chamber 16. The edge 172 of the partial sleeve 166 is preferably bevelled from a leading end 190 towards the base of the sleeve. As the partial sleeve 166 extends into the feed chamber 16, the free end 40 of the film strip 36 rises a sufficient distance to move the free end of the mandrel 136, when the mandrel 136 extends into the chamber. The mandrel 136 then extends into the feed chamber 16. The rotation of the mandrel 136 is started and the vacuum source is activated, when the mandrel 136 has entered the feed bait 116 before. The guide shoe 164 is then reduced in relation to the size of the feed chamber 16a until the guide shoe 164 makes contact with the partial sleeve 166 and a predetermined space 182 defined between the idler roller 180 and the mandrel 136 is defined. that this occurs, the free end 40 of the film strip 36 is directed towards the small space 182. (The free end 40 of the film strip is illustrated partially cut away to form an angled tip.) This is a typical feature of the film but it is not a mandatory requirement for the method and apparatus The mandrel 136 continues rotating The idler roller 180 pinches the guide portion 38 of the film strip 36 against the mandrel 136 and the vacuum pulls the film strip 36 radially towards the shaft of the mandrel 150. After approximately one and one and one half revolutions, the upper portion 38 of the film strip 36 is pinched on the mandrel 136. A vacuum sensor (not shown) placed in the vacuum line it detects the fall in the air flow or decrease in the air pressure resulting from the pinching. The vacuum sensor sends a control, which in response removes the guide shoe 164 and the partial sleeve 166. The upper portion 44 of the film guide is then pulled towards the chamber 16 by means of the mandrel 136 and is wound around the portion guide producing the film roll 62. Referring now to Figure 2, the film roll 62 has an outer rotation 192 (indicated in Figure 2 by means of a dotted line) defining a first film roll radius 194 which is larger that the preliminary radius 142. The winding of the film roll continuing to the main portion 44 of the film strip 36 has reached the film roll 62. This is generally the largest portion of the film strip. The tail portion 42 of the film strip necessarily remains attached to the spool 84 of the film cartridge 30 and extends to the film roll 62. The rotation of the mandrel 136 is stopped before excessive stress is applied to the tail portion. 42. This can be done in many ways. For example, a sensor can detect an increasing load on the mandrel because the tail portion has been reached; or one detector can count the rotation of the film reel and another rotary part; or a detector can measure the length or area of the film strip traveling to the film roll; or the film can be wrapped for a predetermined time. With either of these methods a sliding clutch may be provided on the mandrel to absorb excessive tension. At the end of the winding, the mandrel 136 is removed from the film feed chamber. The vacuum is first deactivated and compressed air or other gas can be blown through the mandrel 136 to promote release of the film roll. At this time the mandrel 136 can be rotated through a revolution approximately to promote release of the film roll. The combination of these effects allows the roll of film to loosen and expand such that the outer turn 196 defines a second radius of the film roll 198 greater than the first radius of the film roll 194. In a preferred embodiment the roll of The film does not expand substantially beyond the throat 17 of the feed bed 16. This can be accomplished in different ways. For example, 1 feed chamber can include a vacuum port (not shown) through which the vacuum can be applied to the film roll in the manner described in US Pat. No. no. 5,608,482. The frame 12 may alternatively have wedges 200 in the middle margin of the groove 17, which reduce in width of the groove to less than the width of the widest portion of the feeding chamber 16 and thus limit the spring of the film roll. The mandrel 136 is then removed from the feed chamber by retracting the mandrel in the spacer 186, leaving the spacer 185 in place against the edge of the film strip 36. Because the radial spacing between the mandrel 136 and the separator 186 is less than the thickness of the film strip 36, the telescopic stretch is substantially prevented. In a currently non-preferred embodiment, the mandrel can be separated from the apparatus in the manner of a spool. Although the reel may be relatively simple, this still helps as an additional part to the camera and the complexity of a release mechanism for separating the reel. In a modality in which the film bridge 86 is used, the film bridge 86 is displaced relative to the camera frame assembly 10, before the mandrel 136 is removed.; so that the film strip 36 can be received by winding a final portion of the film strip in the film roll or by retracting that part of the film strip back to the cartridge 30. The rear opening 28 of the camera frame assembly is then closed and the chamber frame assembly becomes airtight. This may be a single stage in which the light-tight back part 202 is attached to the frame 12 or may include multiple stages. For example, a rear part may be attached above the rear opening followed by a bottom opening being connected to make the assembly airtight. The resulting camera assembly can be a complete camera or a camera sub-unit that requires additional assembly operations to complete. In addition to the above described features, including a film cartridge and a film roll, the camera assembly may also include other conventional camera features well known to those skilled in the art. The film roll 62 may extend telescopically outward during removal of the mandrel 136 or after removal of the mandrel 136 if the camera arc assembly 10 vibrates. A distended portion of the film roll 62 presents a serious risk of pinching or otherwise damaging when the chamber becomes airtight. Thus it is highly desirable, at least once before installing the rear part 2023 or otherwise closing the chamber, to store the film roll 62 completely inside the feed chamber 16 axially (in a direction parallel to the axis of the space of movie 26). The separator 186 can provide axial storage during removal of the mandrel 136, as previously described. The separator 186 can also be replaced or supplemented by one or more rammers. Each tamper is included in the apparatus 52 in a separate station 68, as shown in Figure 21, or as part of the previously described station 68 in which the film roll 62 was formed, or a subsequent station 68. As the separator 186, the pad (s) 300 fix the film roll 62 within the feed chamber 16 during or after removal of the mandrel 136. Each pad 300 includes a linear actuator 106, such as an air cylinder that tampers a head of tamped 302 against the end of the film roll 62 to drive any extended outward portion of the film roll back to the remainder of the film roll and axially store the entire film roll 62 in the feed chamber 16. The tamper head 302 , in the rammer 300 shown in Fig. 21, is fixed to its linear actuator 106. Referring to Figs. 22-24, axial storage may also be achieved by providing a pre-collision partial wall. ada 304 or a post-load wall 306 at the bottom of the chamber 16, the partial wall 304 is provided as a part of the chamber frame assembly 10 and can replace the separator 186. This is less desirable than the use of the separator 186, because the partial wall 304 is subject to the tolerances of the frame assembly and presents a greater risk of inaccurate positioning and incomplete axial storage of the film roll 62 in the feed chamber 16. The post-loaded wall 306 is installed in the chamber frame assembly 10 after removal of the mandrel 136. The post-loading wall 306 may be partial, but preferably complete, ie the post-loading wall 306, after the installation preferably closes the complete end of the feed chamber 16. The post-load wall 306 can be installed in a radial direction to the film space axis 26, as shown in Fig. 23, in which case a spacer 186 or tamper 300 is needed. This is to initially fix the film roll 62 in the feed chamber 16. The afterload wall 306 can be installed in a direction parallel to the axis of the film space 26. As shown in Fig. 24. In this case, the wall post load 306 and wall installation tool 308 together comprise a tamper 300 and the use of separator 186 is optional. Referring now to Figures 31-32 in a particular embodiment the apparatus 52 includes a reel repositioner 400. The reel repositioner 400 is used to prevent the blocking of active light during transport between stations. The camera frame assembly 10, in this embodiment includes an active light blocking closer 402 which is actuated by means of a cam surface 404 of a butterfly wheel 94. Active light blocking closers of this type are described in the US patents. .US. us. 5,614,976 and 5,629,750. The butterfly wheel 94 also engages and reciprocally engages the reel 34 of the film cartridge 30. the term "reciprocally engaged" and the like, used to refer to complementary structures in the cartridge reel 34 and the butterfly wheel 94 which allows the engagement of the butterfly wheel 94 and the spool in only a single rotation orientation in relation to each other. For example, the Advanced Photo System "* cartridge has a spool that has a generally cylindrical bushing with a notch or groove that extends partially along the bushing." A matching throttle wheel has a generally cylindrical shaft with a key that is axially extends in addition to the spool key slot, Figures 25-30 illustrate the active light blocking closer 403 (Universal-ALL 402 closer) and the butterfly wheel 94 of a particular camera frame assembly 10 usable with The invention The Universal Closer [ALL] 402 has a drive unit 406 which is pivotally mounted to the frame 12. The drive unit 406 has a Universal coupling [ALL] 408 at the end 408 at one end and a first sector 410 at The other Universal coupling [ALL] 408 extends into the chamber of the cartridge 14 to engage the active light lock 412 of the cartridge 30. The Universal coupling 408 has a fin 414 extending radially outwardly from the pivot axis 416 of the drive unit 406. The first sector 410 is interwoven with teeth of a second sector 420 that is pivotally mounted to the frame 12. The second sector 4020 includes a follower 422 which is pushed towards the C-shaped cam surface 404 of the butterfly wheel 94 by means of a spring (not shown). A sensor lever 426 is pivotably mounted on the frame 12 in the cartridge chamber 14 adjacent to the intermediate section 20. The sensor lever 426 is pushed backward, that is towards the film strip 36 in the complete chamber; and has an extended contact pad at the rear 428 which limits the contact of the film strip to an area outside the exhibition area. A tongue 430 on the sensor lever 426 is placed in contact with the partial flap 414 and blocks the rotation of the drive unit 406 when the presence of the film strip 36 is recorded. In this position in which the presence of the the film, the follower 422 remains separate from the cam surface 404 of the butterfly wheel 94 and the active light lock 412 remains open. In the complete chamber when the film strip has been rewound in the cartridge, the sensor lever 426 moves backward and the drive unit 406 rotates to an open position without blocking in the light of the film, in the which follower 422 rests against the cam surface 404 of the butterfly wheel 94. The active light lock 412 is partially closed by that movement of the unit of - -: -, drive 406, which:, consists ^ &; *%. aprQ imadaent 10 degrees of rotation. As the butterfly wheel 94 rotates further, the follower 422 travels along the camming surface 404 and 15 enters the space 432 of the C-shaped cam surface 404. This movement of the follower 422 pivots the sectors 410,420 without a closed blocking position to the light and completely closes the active light lock 412. By returning again to FIGS. 25-30, the sensor lever 426 does not reliably block the rotation of the drive unit 406 until the film 36 has been pre-coiled and rear part 202 has been installed on the camera frame assembly 10. Prior to this, the position of active light lock 412 is determined by position 25 of follower 422 on the surface 40 of toothed wheel 94. If the follower 422 is placed on the outer edge of the C-shaped cam surface 404, then active blocking to the light 412 is opened. When the follower 422 enters the space 432 in the surface d and cam 404, the active light lock 412 closes. Since the sensor lever 426 is not effective until the rear portion 202 is in place, the active light lock 412 closes even if the film strip 36 is present in the active light lock 412. It is likely to occur damage of the film strip. Referring now to FIGS. 31-32, the reel repositioner 400 can be placed in a separate station 68 or part of a described described station positioned after the station providing a thrust of the guide 38 of the film strip 36 from the cartridge. The reel repositioner 400 has a sleeve 104 that moves to engage with the reel of the film cartridge 34, in the same manner as the sleeve 104 described above. The reel repositioner 400 also has a support 434 having a grip head 436 that moves toward and away from the intermediate section 20 of the camera frame assembly 10. The reel repositioner 400 is used after the guide portion 38 of the film strip 36 has advanced on the intermediate section 20 by means of a film transport in the manner previously described. The bracket 434 has a linear actuator 106 which advances the gripping head 436 to an active position. In the active position, the gripping head 436 engages the guide portion 38 by means of friction or by the suction provided by a vacuum line (not shown) and removes the guide portion 38 in a fixed position within and in relation to the intermediate section 20 of the chamber frame assembly 10. The reel repositioner 400 has a sensor 438 which is directed towards a spool position indicator 440 at the end of the cartridge 30 or towards an indicator (not shown) provided as part of the sleeve 104, such as a digital 0-axis encoder, (reel position indicators are well-known to those skilled in the art and are present in ~ - io »cartusbos-dß p¡ ± icula Advanced Photo Sensor 438 detects the rotational position of the cartridge 34 and the butterfly wheel 94 in relation to the drive unit 406 and sends a signal along a signal path 442 to a control 444. The control 444, in response to the signal from the sensor, drives the drive of a sleeve 104 and rotates the spool 34 and the butterfly wheel 94 to provide a required net rotation 0 less than 360 degrees. The degree of rotation is that necessary to ensure that the cartridge reel 34 is stopped within the security zone 446, that is, the follower 422 of the universal closure 402 is placed on the cam surface 404. It is currently preferred to place the 5 reel 34 in the approximate half of the C-shaped cam surface 404. It is preferred that the rotation be only in the rewinding direction, since the rotation in the forward direction presents the risk that the film wrinkle or other distortion occurs. The control 44 of the sleeve driver can be continued until the free end of the film strip 36 is inserted into the feed chamber. A detector 124 may be positioned to register optically or in any other way when the free end 40 reaches the space of the supply chamber 16a and sends a signal to the controller (not shown) to stop the advance. Referring now to Figures 33-37, in one -particular modality, the apparatus 42 includes a butterfly wheel aligner 500, which is used with a sleeve 104. The aligner 500 and the sleeve 104 are associated with the cartridge mover 76 and are collectively referred to herein as an advancer-positioner. cartridge 502. It is preferred that the cartridge mover 76, the aligner 500, and the sleeve 104 are preferably all in the same station 68 of the apparatus 52, but the cartridge mover 76 may be provided in the upstream station 68 if desired . The cartridge mover 76, the aligner and the sleeve 104 are positioned and moved relative to the location of the camera frame assembly 10 in the receiver 54 in the same manner previously described for other components 56. The cartridge mover 76 operates as previously described for placing the film cartridge 30 into the chamber of the cartridge 14. The active light lock 412 can be opened before the cartridge 30 is placed, as previously described. The aligner 500 includes a pair of sub-components; a jack 504 and a one-way mechanism 506. The jack 504 has a shaft 508 that is coextensive with the axis of the cartridge chamber 15 when the aligner 500 is in its active position. The cartridge 504 is adapted to engage the butterfly wheel 94 and holds the butterfly wheel 94 in alignment with the jack axis 508 and allows the rotation of the butterfly wheel 94 about the axis of the jack 508. In the aligner 500 shown in the figures, ^ the cat. 504 - tiené- unrposte - freely rotatable cylindrical 510 which is received by a reduced cylindrical post-hole 512 in the butterfly wheel 94. The one-way mechanism 506 allows the butterfly wheel 94 to rotate about the axis of the jack 508 in the direction of advancement, indicated in Figure 34 by arrow 514, but prevents the rotation of the butterfly wheel 94 about the axis of the jack 408 in a rewinding position, indicated by the arrow 516. The detailed characteristics of a 506 sense mechanism are not critical. A variety of one-way mechanism are well known having a wide variety of features, for example the one-way mechanism can be a ratchet and catch mechanism that forms a unit with the jack. It is currently preferred that however the one-way mechanism 506 be a ratchet detent as shown in Fig. 34. The ratchet retainer 506 is separate from the cat 504 and the butterfly wheel 94 has a serrated margin 518 which is adapted to act as a ratchet wheel for the ratchet detent 506. In this embodiment the ratchet catch 506 and the jack 504 are each attached to a rigid support 5320, in a fixed relationship with each other. The ratchet retainer 506 has a lever arm 522 that is pivotally mounted to the bracket 520 and is arranged to engage the butterfly wheel 94. The ratchet catch 506 is urged toward the butterfly wheel 94. A stop 524 limits rotation - of the lever arm 522 when the butterfly wheel 94 is not present. The thrust is provided by means of a spring 526 which engages the lever arm 522 and the stop 526. The teeth 528 of the butterfly wheel 94 and a latching portion 530 of the lever arm 522 are shaped to allow rotation in the direction of advance, but avoid rotation in the direction of re-winding. This one-way mechanism has the advantages of simplicity and the wear to the thumbwheel that can be replaced as needed during the recycling of the camera can be largely limited. With the aligner 500 shown in Figures 33-37, the butterfly wheel 94 is pre-installed in the camera frame assembly 10 by means of another component (not shown) of the apparatus, the butterfly wheel 94 can alternatively be installed in the the camera frame assembly 10 by means of the aligner 500. In this case, Figure 33 would illustrate the conclusion of this stage in which the butterfly wheel 94 has been seated in the frame 12. the cartridge 30 could be positioned in the cartridge chamber 14, before or after the installation of the butterfly wheel 94. After the cartridge 30 has been placed in the cartridge chamber 14 of the chamber frame assembly 10, the sleeve 104 is moved and rotated in the same manner previously described. The sleeve 104 is placed in an axial proximity close to the reel 34 of the film cartridge 30 _? _ Is rotated; the ... dilection, of re-winding. During turning, the sleeve 104 is urged against the spool 34 by pushing the key of the sleeve 110 axially towards the cartridge 30 and pushing the cartridge 30 towards the drive key of the thumbwheel 100 until the drive keys 100,110 engage with the cartridge. the respective engagement portions 102,112 of the cartridge reel 34. The butterfly wheel 95 does not rotate, due to the rotation of the butterfly wheel 94 in the rewinding direction is prevented by means of the one-way mechanism 506. While the sleeve 106 is rotated in the rewinding direction and the driving keys 100, 110 are pushed to the coupling with the spool 34, the cat 504 continuously retains the throttle key 100 in axial alignment with the sleeve 104. This retention of the alignment decreases the average time needed to couple to the 100.110 driving boosters and the 34 reel and reduces the risk that the driving wheel of the wheel of the spring 100 and the spool 34 retract and move out of alignment with the axis of the cartridge chamber 15. After the engagement of the butterfly wheel 94 and the spool 34, the spool 34 and the sleeve 104; the direction of rotation of the sleeve 104 is reversed and the spool 34 and the butterfly wheel 94 are rotated in the re-bridging direction. This rotation in the advancing direction continues until the guide zig-zag 38 of the film strip 36 is advanced from the cartridge 30. The guide portion 38 is then transported to the feed bed 16 in the previously described manner. If this transport is desired, it can be carried out in the same station 68 as the advancer-positioner of the cartridge 502 and a film bridge 86 can be used in the manner described above. After attaching to the feeding chamber 16, the film strip 36 is wound in a roll of film 62 in the manner described above. The invention has been described in detail with particular reference to certain preferred embodiments, but it will be understood that variations and modifications may be made within the spirit and scope of the invention.
