Definitions
- the present invention relates to an apparatus for manufacturing photographic filmstrips from a long strip of photographic film, especially for manufacturing photographic filmstrips having one or two perforations and data per picture frame along one or both of lateral sides thereof by perforating, data recording and cutting the long film.
- Leader-advancing type photographic film cassette have been disclosed, e.g., in U.S.P. No. 4,846,418, in which the whole length of a filmstrip is contained within a cassette shell, and a film leader of the filmstrip can be advanced to the outside of the cassette shell by rotating a spool of the cassette.
- a camera need not have such a sprocket wheel that has conventionally been used for feeding the film leader to the take-up spool of the camera.
- the filmstrip may be advanced by rotating the take-up spool. Therefore, the filmstrip of the leader-advancing type cassette need not have a lot of successive perforations which like conventional 135-type filmstrips have for engagement with the sprocket wheel or the take-up spool.
- the filmstrip of the leader advancing type cassette has at least a perforation per picture frame.
- the perforation is intended to be detected by a photo-sensor in the camera to determine each frame exposure location and position it in an exposure aperture of the camera. Since these perforations for frame positioning are disposed in association with the frame exposure locations, the filmstrip of the leader advancing type cassette, hereinafter referred to as a new type filmstrip, has no positioning perforation in its leader and trailer where no picture frame is to be recorded.
- a section which extends over the frame exposure locations of each individual filmstrip will be referred to as a recording section.
- apparatuses for manufacturing the new type filmstrip have been suggested, one of which uses a die set having a number of punches and dies corresponding to the number of frame exposure locations to be provided in the individual filmstrips formed from the long film.
- the apparatus makes the corresponding number of perforations at a time in the recording section of each individual filmstrip.
- the number of frame exposure locations per filmstrip will be referred to as film frame number.
- a similar method has conventionally been applied to manufacturing 110-type filmstrips.
- the long film 12 is fed from a roll 10 to a first vacuum suction chamber 15 through a dancer roller 13 and a sub-feed rollers 14.
- the suction chamber 15 transiently stores an appropriate length of the long film 12 before being fed to the die set 17 through a pass roller 16.
- the die set 17 has a punch holder 19 with the same number of punches 18 as the film frame number, and a dies plate 21 with the corresponding number of dies 20.
- the punches and dies 18 and 20 are arranged at the same intervals as the frame exposure locations.
- An air cylinder 22 is driven to move the punch holder 19 down to the dies plate 21 while the long film 12 stops on the dies plate 21, making the same number of perforations as the film frame number at a time.
- first vacuum suction drum 24 Downstream of the die set 17 are disposed a first vacuum suction drum 24, a second vacuum suction chamber 25, a second vacuum suction drum 26, a side-printer 27 and a cutter 28 in serial fashion.
- the first and second suction drums 24 and 26 have suction holes formed through respective peripheral surfaces, and are driven by servo motors 30 and 32, respectively.
- the suction drums 24 and 26 transport the film 12 while sucking it on the peripheral surfaces.
- an encoder 31 connected to the servo motor 30 monitors the rotational amount of the drum 24 to detect the transported length of the film 12.
- the drum 24 starts rotating after each die-punching the perforations P in the film 12, and stops rotating when the film 12 is transported by a unit length which is predetermined in accordance with the film frame number.
- the next recording section to be perforated is positioned in the die set 17.
- the perforated section of the film 12 is transported through the first suction drum 24 to the second suction chamber 25 to transiently store an appropriate length of the film 12 before being fed to the cutter 28.
- the film 12 is transported from the suction chamber 25 to the cutter 28 through the second suction drum 26, while an encoder 33 connected to the servo motor 32 monitors the rotational amount of the second suction drum 26 to detect the transported length of the film 12.
- the detection signal from the encoder 33 is sent to the side-printer 27.
- the side-printer 27 optically records data such as the name of film manufacturer, frame serial numbers and the like as latent images of characters and bar codes along one or both of lateral sides of the film 12 while the film 12 is being transported through the second suction drum 26.
- the side-printer 27 is movable toward a peripheral position of the second suction drum 26 where the transported film 12 tightly fit on, so that the side-printer 27 faces the photosensitive emulsion surface of the film 12 at a constant distance.
- the peripheral position may be referred to as a side-print position.
- the second suction drum 26 stops rotating when it has transported the film 12 by the predetermined unit length. Then, the cutter 28 is actuated to cut the film 12 into individual filmstrips.
- the new type filmstrip may have variations in the film frame number like the conventional filmstrips.
- the apparatus as shown in Fig. 13 is provided with interchangeable punch holders having different numbers of punches from one another.
- One of the punch holders is selected in correspondence with the film frame number of the filmstrips designated to be produced.
- the unit length for the transport of the film 12 through the suction drums 24 and 26 is changed in accordance with the selected film frame number.
- the second suction chamber 25 absorbs the variation by changing the storing length of the film 12.
- the side-print position is unchanged independently of the film frame number.
- the number of times of recording as well as a side-print end position vary depending on the film frame number, as a side-print end position.
- the above-described apparatus needs two suction drums 24 and 26, two servo motors 30 and 32, and two encoders 31 and 33 for transporting the film 12 by the unit length relative to the die set 17 and the cutter 28, respectively, its mechanism and control system are complicated. Moreover, since the drums 24 and 26 must have a diameter large enough to ensure the suction of the film 12, the distance between the cutter 28 and side-printer 27, and thus the length of the film 12 from a cut position B to the side-print position C must correspondingly be long, as is shown in Fig. 14, wherein the cut position B is a position to cut trailing ends 6 of individual filmstrips 5, that is, an innermost end in a cassette shell.
- a film trailer length L3 into a range from 50 mm to 100mm or so, wherein the film trailer length L3 represents the length from the trailing end 6 of the individual filmstrip 5 to the start of its recording section.
- the length from the cut position B to the side-print position C would beyond the desirable trailer length L3, as is shown in Fig. 15.
- CH-A-554 225 discloses a device for cutting and perforating segments with predetermined unit lengths from a long foil, whereby cutting and punching is actuated simultaneously.
- the perforations extend perpendicularly to the transport direction of the foil such that each segment irrespective of its length has the same number of peforated holes. Variable lengths can be achieved by varying the distance between cutting device and punching device.
- JP-A-6 170 795 on which the preamble of claim 1 is based discloses a perforation device for perforating filmstrips that comprises a die set unit with die sets and respective punches which are aligned along the feed direction of the film.
- the device is designed for eliminating the need for exchanging the die set when filmstrips having different numbers of perforations are to be made.
- a control part is operated to actuate the corresponding punches and to actuate a transporting device to transport said film by a unit length after actuation of the punches, said unit length being dependent on the number of perforations.
- two rolls are provided between which the film is transiently stored, thereby freely extending such that different unit film lengths can be accommodated. It is foreseen that after this device the filmstrip is cut in a further device.
- An object of the present invention is to provide a simple and efficient apparatus for manufacturing filmstrips which has a designating device for designating the number of perforations per filmstrip, a perforator capable of making a variable number of perforations at a time in a long continuous film, and a transporting device for transporting said film by a length dependent on the designated number number of perforations, whereby the transport of the film needs only be interrupted once per filmstrip.
- the film length adjusting device sets the length of the continuous film from a cut position of the cutter to a punching position of the die set device into a value a number M of times as long as the unit length, plus a length from a first end of each filmstrip, which is to be cut at the cut position, to a first perforation to be made at the punching position in each filmstrip.
- a filmstrip manufacturing apparatus which has a side-printer between a stationary perforator and a stationary cutter, the side-printer being capable of printing data on the long film along one or both lateral sides of recording sections of individual filmstrips to be made from the long film, whereby even with side-printing the transport of the film needs only be interrupted once per filmstrip.
- a suction drum is disposed between the die set and the cutter, to transport the film toward the cutter by a unit length after each die-punching, and a pair of feed rollers are disposed between the cutter and the suction drum, and one of the feed rollers has a larger diameter than the other.
- a side-printer is arranged to record data on the film at a peripheral position of the larger feed roller. In this way, it is possible to dispose the side-printer closer to the cutter enough to continue side-printing without intermediate stops in the recording section of each filmstrip.
- the distance between the cut position and the peripheral position for side-printing is preferably set equal or less than the length from the first end to the first perforation of each filmstrip.
- a filmstrip manufacturing apparatus is adapted to manufacture filmstrips in a format as shown in Fig. 2, wherein each film exposure location 40 is designated by a perforation P.
- the filmstrip 5 has a length L1 which is variable depending on its film frame number N, i.e., the number of the frame exposure locations 40 to be provided in the filmstrip 5.
- the perforations P1 to P N are disposed at constant intervals L2 in a recording section of each individual filmstrip 5. As shown by hatching, both lateral sides of the filmstrip 5 serve as side-print zones 42.
- a long continuous strip of film 12 is fed from a roll 10 through a dancer roller 13, sub-feed rollers 14, a vacuum suction drum 15 and a pass roller 16 into a die set device 45, like the apparatus shown in Fig. 13.
- the die set device 45 is constituted of first to third die sets 46, 47 and 48 which are aligned in continuity along a film transport path, and may be individually actuated.
- the first die set 46 is constituted of a punch holder 46a having fifteen punches 50 arranged at the same interval L2 as the perforations P1 to P N , a dies plate 46b having fifteen dies 51 arranged in correspondence with the punches 50, and an air cylinder 46c for moving the punch holder 46a downward.
- the second and third die sets 47 and 48 are each constituted of a punch holder 47a or 48a having ten punches 50 arranged at the same interval L2 as the perforations P1 to P N , a dies plate 47b or 48b having ten dies 51 arranged in correspondence with the punches 50, and an air cylinder 47c or 48c for moving the punch holder 47a or 48a downward.
- the three die sets 46, 47 and 48 are arranged such that all the punches 50 and the dies 51 as well are spaced at the same interval L2 along the film transport path.
- the die set device 45 can make a series of perforations P1 to P N per one stroke of die-punching while selecting the film frame number N among three variations: 15-exposure, 25-exposure and 35-exposure formats.
- 15-exposure format filmstrips only the first die set 46 is actuated.
- 25-exposure format filmstrips the first and second die sets 46 and 47 are actuated simultaneously.
- 35-exposure format filmstrips all the three die sets 46 to 48 are simultaneously actuated.
- the dies plates 46b, 47b and 48b are stationary, and the same effect is achieved by merely actuating the punch holders 46a, 47a and 48a, the dies plates 46b, 47b and 48b may be replaced by a single dies plate extending over the three punch holders 46a to 48a.
- a film length adjusting mechanism 58 which is constituted of pass rollers 53 and 54, and a movable roller 56 mounted movable in a vertical direction inside a chamber 55 which is disposed between the pass rollers 53 and 54.
- a vacuum suction drum 60 is disposed downstream of the film length adjusting mechanism 58, to transport the long film 12 by a unit length which is predetermined in accordance with the film frame number N.
- the suction drum 60 sucks the long film 12 to not-shown suction holes formed through a peripheral surface of the drum 60.
- the suction drum 60 is driven by a servo motor 61, while an encoder 62 monitors the rotational amount of the suction drum 60 through the servo motor 61.
- the long film 12 is transported from the suction drum 60 to a cutter 28 through a pair of feed rollers 64 and 65 having smaller diameters than the suction drum 60.
- a side-printer 27 is disposed near the feed roller 65 to print film data as character data and bar code data along both lateral sides of the long film 12 in the side-print zone 42 of the individual filmstrips 5 to be formed from the long film 12.
- the cutter 28 cuts off the individual filmstrips 5 from the long film 12 at the variable length L1.
- the cutter 28 has first and second knife edges 28a and 28b respectively for cutting a trailing end 6 of a films trip 5 and a leading end 7 of an adjacent preceding filmstrip 5 in the long film 12.
- Fig. 5 shows the relationship between the long film 12 and two adjacent filmstrips 5a and 5b to be cut off therefrom.
- a leading end 7a of the preceding filmstrip 5a and a trailing end 6b of the following filmstrip 5b are simultaneously cut by the edges 28b and 28a of the cutter 28, respectively. Since a trailing end 6a of the preceding filmstrip 5a has been cut at the preceding cutting stroke, the filmstrip 5a is cut off from the film 12 when its leading end 7a is cut by the edge 28b.
- the cutter 28 preferably has a pair of punches in addition to the knife edges 28a and 28b to provide engaging holes 9 concurrently with cutting the long film 12 into individual filmstrip 5, the engaging holes 9 being used to secure the trailing end 6 to a spool of a photographic film cassette.
- the film length adjusting mechanism 58 is adapted to adjust the length of the film 12 extending between a cut position B defined by the knife edge 28a of the cutter 28 and a punching position A defined by the leftmost punch and die 50a and 51a of the first die set 46 in Fig. 4.
- the movable roller 56 is movably mounted to a supporting block 70 which is movable along a pair of vertical guide shaft 71.
- a timing belt 72 is securely connected to the supporting block 70, and is suspended between teethed pulleys 73 and 74.
- the pulley 74 is driven by a servo motor 75 to move the supporting block 70 and thus the movable roller 56 in the vertical direction.
- An encoder 76 is connected to the other pulley 73 to detect position of the movable roller 56.
- the movable roller 56 may be stopped at one of three predetermined positions X, Y and X, as is shown in Fig.
- a film buffer length such that the length of the film 12 extending from the cut position B to the punching position A, hereinafter referred to as a film buffer length, is set at a value determined based on the unit length L4 for the designated kind of filmstrip, and a film trailer length L3 as well.
- the film trailer length L3 is the length from the trailing end 6 to a first perforation P1 of the individual filmstrip 5, which is to be formed by the die and punch 50a and 51b at the punching position A.
- the length of the film 12 between a trailing end 6 being positioned at the cut position B, on one hand, and a trailing end 6 of a filmstrip 5 being positioned in the die set device 45, on the other hand is set at a value an integral number M of times as long as the unit length L4 for the designated kind filmstrips. Accordingly, it is possible to actuate the die set device 45 and the cutter 28 in synchronism with each other each time the film 12 stops after being transported by the unit length L4.
- the movable roller 56 is moved in the position X when manufacturing 15-exposure filmstrips from the film 12, to set the film buffer length M times as long as a unit length L4a for 15-exposure filmstrip, plus the film trailer length L3, that is, L4a x M + L3.
- the movable roller 56 is moved in the position Y, so that the film buffer length becomes M times as long as a unit length L4b for 25-exposure filmstrip, plus the film trailer length L3, that is, L4b x M + L3.
- the film buffer length is M times as long as a unit length L4c for 35-exposure filmstrip, plus the film trailer length L3, that is, L4c x M + L3.
- the positioning of the movable roller 56 may be manually executed, so the servo motor 75 is dispensable.
- the position Z of the movable roller 56 to the 15-exposure filmstrips, and the position Y to the 25-exposure filmstrips by using a larger integral number M + ⁇ as a factor to define the film buffer length for the 15-exposure filmstrips than an integral number M which is used as a factor to define the film buffer length for the 25-exposure filmstrips.
- the position X may be assigned to the 35-exposure filmstrips by using a smaller integral number M - ⁇ as a factor to define the film buffer length for the 35-exposure filmstrips.
- the feed rollers 64 and 65 are rotated at the same circumferential speed as that of the suction drum 60 so the film 12 may not be loosened.
- the side-print position C is set in a peripheral position of the feed roller 65 where the film 12 is in tight contact with the roller 65.
- the feed roller 65 has a larger diameter than the other feed roller 64, so as to permit the tight contact.
- the side-printer 27 may be disposed closer to the cutter 28, as is shown in Fig. 8, compared with the case shown in Fig. 14. Accordingly, it is possible to make the distance between the side-print position C and the cut position B equal to or less than the film trailer length L3, as is shown in Fig. 2.
- the distance between the positions B and C may be about 50 mm to 100 mm, preferably 50 mm to 70 mm, and more preferably 60 mm to 70 mm. In this way, when the film 12 stops to be cut by the cutter 28, the print position C is located before or at the first perforation P1 defining the start or front end of the recording section in the film transporting direction. Accordingly, side-printing can be performed without intermediate stops through the recording section of each individual filmstrip.
- pass rollers 67 and 69 in a manner as shown in Fig. 9, instead of the pass roller 54, so that the photosensitive emulsion surface of the film 12 will not contact the suction drum 60.
- This embodiment prevents the photosensitive emulsion surface of the film 12 from being scratched or damaged by sucking.
- a controller 80 controls the operation of the above-described apparatus by a controller 80, as shown in Fig. 10.
- a console 81 serves as an input device for the operator to enter the film frame number N of the filmstrips to be manufactured.
- the controller 80 selectively drives the air cylinders 46c, 47c and 48c to actuate the first, or the first and second, or all of the die sets 46, 47 and 48, to form fifteen, twenty-five, or thirty-five perforations at a time, respectively.
- the controller 80 drives the servo motor 61 to rotate the suction drum 60 to transport the film 12 by the unit length L4, which is determined in accordance with the film frame number N, while monitoring output signals from the encoder 62.
- the controller 80 concurrently drives the servo motor 75 to move the movable roller 56 into one of the three positions X, Y and Z in accordance with the film frame number N, while monitoring output signal from the encoder 76.
- the controller 80 also actuates the side-printer 27 and the cutter 28 with respect to the output signal from the encoder 62 under the control of the controller 80.
- the controller 80 sequentially controls the respective parts in accordance with a program stored in a ROM 83.
- the controller 80 actuates the first die set 46 through the air cylinder 46c to make fifteen perforations P1 to P15 through the film 12. Simultaneously, the cutter 28 is actuated to cut a portion of the film 12 where no perforation is made. Thereafter, the film 12 is transported by the unit length L4a for 15-exposure filmstrip.
- the trailing end 6 of the filmstrip 5 having the fifteen perforations in its recording section is placed in the cut position B. Simultaneously therewith, the next recording section to be perforated is placed between the punch holder 46a and the dies plate 46b of the first die set 46. Then, the controller 80 stops transporting the film 12, and actuates the cutter 28 and the first die set 46 at the same time.
- the film 12 is transported by the unit length L4a, and then the first die set 46 is actuated and, simultaneously, the cutter 28 is actuated to cut the trailing end 6 of the next filmstrip 5 and the leading end 7 of the filmstrip 5 whose trailing end 6 has previously been cut.
- the filmstrip 5 with fifteen perforations is cut off the film 12 into an individual 15-exposure filmstrip. In this way, die-punching and cutting are performed in synchronism with each other.
- the side-printer 27 While the film 12 is transported by the unit length L4a after each cutting, the side-printer 27 starts printing when the front end of the recording section immediately after the first perforation P1 is located in the print position C, and continuously print data of 15-exposure filmstrip along the side-print zone 42 in the recording section.
- the side-printer 27 is disposed relative to the cutter 28 such that the side-printer 27 can start printing immediately after the start of film transport.
- the first and second die sets 46 and 47 are simultaneously actuated to make twenty-five perforations P1 to P25 at a time through the film 12 and, thereafter, the suction drum 60 is driven to transport the film 12 by the unit length L4b for 25-exposure filmstrip. Since the leading end and the trailing end of two adjacent filmstrips having fifteen perforations P1 to P15 formed therethrough are cut by the cutter 28 in synchronism with the die-punching of the first and second die sets 46 and 47, the preceding one of the two filmstrips is cut off the film 12 into an individual 15-exposure filmstrip. But the leading end of the following filmstrip is transported farther than the cutter 28 as a result of the rotation of the suction drum 60 by the unit length L4b for 25-exposure filmstrip.
- the film buffer length is L4 + L3 for any film frame number N, by selecting a factor "1" to multiply the unit length L4 in the above-described definition. In this way, merely a defective filmstrip will be produced at each film frame number change.
- die-punching of the first and second die sets 46 and 47 and cutting of the cutter 28 are repeated in synchronism with each other, and the side-printer 27 prints data of 25-exposure filmstrip along the side-print zone 42 while the film 12 is transported by the unit length L4b after each die-punching, in the same way as above, to produce 25-exposure filmstrips.
- the movable roller 56 is moved to the position Z to adjust the film buffer length to the unit length L4c for 35-exposure filmstrip. Then, the first to third die sets 46 to 48 are simultaneously actuated to make thirty-five perforations P1 to P35 at a time. Thereafter, the suction drum 60 is driven to transport the film 12 by the unit length L4c, while the side-printer 27 prints data of 35-exposure filmstrip along the side-print zone 42. The same operation is repeated to produce 35-exposure filmstrips in continuous succession.
- the present invention is applicable to a case where a pair of perforations P1a and P1b; P2a and P2b; ... P N a and P N b are provided for each frame exposure location, as is shown in Fig. 11.

Description
- The present invention relates to an apparatus for manufacturing photographic filmstrips from a long strip of photographic film, especially for manufacturing photographic filmstrips having one or two perforations and data per picture frame along one or both of lateral sides thereof by perforating, data recording and cutting the long film.
- Leader-advancing type photographic film cassette have been disclosed, e.g., in U.S.P. No. 4,846,418, in which the whole length of a filmstrip is contained within a cassette shell, and a film leader of the filmstrip can be advanced to the outside of the cassette shell by rotating a spool of the cassette. With this type of film cassette, a camera need not have such a sprocket wheel that has conventionally been used for feeding the film leader to the take-up spool of the camera. Once the film leader has been engaged with the take-up spool, the filmstrip may be advanced by rotating the take-up spool. Therefore, the filmstrip of the leader-advancing type cassette need not have a lot of successive perforations which like conventional 135-type filmstrips have for engagement with the sprocket wheel or the take-up spool.
- Still, in order to advance the filmstrip one frame after each exposure, also the filmstrip of the leader advancing type cassette has at least a perforation per picture frame. The perforation is intended to be detected by a photo-sensor in the camera to determine each frame exposure location and position it in an exposure aperture of the camera. Since these perforations for frame positioning are disposed in association with the frame exposure locations, the filmstrip of the leader advancing type cassette, hereinafter referred to as a new type filmstrip, has no positioning perforation in its leader and trailer where no picture frame is to be recorded. Hereinafter, a section which extends over the frame exposure locations of each individual filmstrip will be referred to as a recording section.
- For providing perforations only in the recording sections of the filmstrips to be made frame the long film, it is hard to use a conventional perforating method for the 135-type film, such as disclosed in JPA 61-214999 and JPY 4-2800, wherein perforations are formed at constant intervals all along the long film while the long film is continuously transported.
- For this reason, apparatuses for manufacturing the new type filmstrip have been suggested, one of which uses a die set having a number of punches and dies corresponding to the number of frame exposure locations to be provided in the individual filmstrips formed from the long film. The apparatus makes the corresponding number of perforations at a time in the recording section of each individual filmstrip. Hereinafter, the number of frame exposure locations per filmstrip will be referred to as film frame number. A similar method has conventionally been applied to manufacturing 110-type filmstrips.
- In Fig. 13 showing such an apparatus, the
long film 12 is fed from aroll 10 to a firstvacuum suction chamber 15 through adancer roller 13 and asub-feed rollers 14. Thesuction chamber 15 transiently stores an appropriate length of thelong film 12 before being fed to thedie set 17 through apass roller 16. - The die
set 17 has apunch holder 19 with the same number ofpunches 18 as the film frame number, and adies plate 21 with the corresponding number ofdies 20. The punches and dies 18 and 20 are arranged at the same intervals as the frame exposure locations. Anair cylinder 22 is driven to move thepunch holder 19 down to thedies plate 21 while thelong film 12 stops on thedies plate 21, making the same number of perforations as the film frame number at a time. - Downstream of the
die set 17 are disposed a firstvacuum suction drum 24, a secondvacuum suction chamber 25, a secondvacuum suction drum 26, a side-printer 27 and acutter 28 in serial fashion. The first andsecond suction drums servo motors suction drums film 12 while sucking it on the peripheral surfaces. - While the
first suction drum 24 is driven by theservo motor 30, anencoder 31 connected to theservo motor 30 monitors the rotational amount of thedrum 24 to detect the transported length of thefilm 12. Thedrum 24 starts rotating after each die-punching the perforations P in thefilm 12, and stops rotating when thefilm 12 is transported by a unit length which is predetermined in accordance with the film frame number. Thus the next recording section to be perforated is positioned in the dieset 17. - The perforated section of the
film 12 is transported through thefirst suction drum 24 to thesecond suction chamber 25 to transiently store an appropriate length of thefilm 12 before being fed to thecutter 28. Thefilm 12 is transported from thesuction chamber 25 to thecutter 28 through thesecond suction drum 26, while anencoder 33 connected to theservo motor 32 monitors the rotational amount of thesecond suction drum 26 to detect the transported length of thefilm 12. The detection signal from theencoder 33 is sent to the side-printer 27. - In synchronism with the detection signal, the side-
printer 27 optically records data such as the name of film manufacturer, frame serial numbers and the like as latent images of characters and bar codes along one or both of lateral sides of thefilm 12 while thefilm 12 is being transported through thesecond suction drum 26. The side-printer 27 is movable toward a peripheral position of thesecond suction drum 26 where the transportedfilm 12 tightly fit on, so that the side-printer 27 faces the photosensitive emulsion surface of thefilm 12 at a constant distance. The peripheral position may be referred to as a side-print position. - The
second suction drum 26 stops rotating when it has transported thefilm 12 by the predetermined unit length. Then, thecutter 28 is actuated to cut thefilm 12 into individual filmstrips. - Meanwhile, the new type filmstrip may have variations in the film frame number like the conventional filmstrips. To cope with the different film frame numbers, the apparatus as shown in Fig. 13 is provided with interchangeable punch holders having different numbers of punches from one another. One of the punch holders is selected in correspondence with the film frame number of the filmstrips designated to be produced. Also the unit length for the transport of the
film 12 through thesuction drums die set 17 to thecutter 28 changes with the change of the unit length, thesecond suction chamber 25 absorbs the variation by changing the storing length of thefilm 12. It is to be noted that the side-print position is unchanged independently of the film frame number. Of course, the number of times of recording as well as a side-print end position vary depending on the film frame number, as a side-print end position. - Since the above-described apparatus needs two
suction drums servo motors encoders film 12 by the unit length relative to thedie set 17 and thecutter 28, respectively, its mechanism and control system are complicated. Moreover, since thedrums film 12, the distance between thecutter 28 and side-printer 27, and thus the length of thefilm 12 from a cut position B to the side-print position C must correspondingly be long, as is shown in Fig. 14, wherein the cut position B is a position to cuttrailing ends 6 ofindividual filmstrips 5, that is, an innermost end in a cassette shell. However, to make use of as much area of theindividual filmstrip 5 as possible, it is desirable to limit a film trailer length L3 into a range from 50 mm to 100mm or so, wherein the film trailer length L3 represents the length from thetrailing end 6 of theindividual filmstrip 5 to the start of its recording section. According to the apparatus as shown in Figs. 13 and 14, the length from the cut position B to the side-print position C would beyond the desirable trailer length L3, as is shown in Fig. 15. - To solve this problem, it is necessary in the above-described apparatus to start side-printing while the
film 12 is transported through thedrum 26, interrupt side-printing while thefilm 12 stops to be cut by thecutter 28, and restart side-printing in synchronism with the start of the next film transport. Because the transport speed of the film inevitably changes immediately before and after the film stops, side-printed images would be damaged at the interrupted portion. - CH-A-554 225 discloses a device for cutting and perforating segments with predetermined unit lengths from a long foil, whereby cutting and punching is actuated simultaneously. The perforations extend perpendicularly to the transport direction of the foil such that each segment irrespective of its length has the same number of peforated holes. Variable lengths can be achieved by varying the distance between cutting device and punching device.
- JP-A-6 170 795 on which the preamble of
claim 1 is based, discloses a perforation device for perforating filmstrips that comprises a die set unit with die sets and respective punches which are aligned along the feed direction of the film. The device is designed for eliminating the need for exchanging the die set when filmstrips having different numbers of perforations are to be made. Depending on the number of perforations desired, a control part is operated to actuate the corresponding punches and to actuate a transporting device to transport said film by a unit length after actuation of the punches, said unit length being dependent on the number of perforations. After the perforation device, two rolls are provided between which the film is transiently stored, thereby freely extending such that different unit film lengths can be accommodated. It is foreseen that after this device the filmstrip is cut in a further device. - An object of the present invention is to provide a simple and efficient apparatus for manufacturing filmstrips which has a designating device for designating the number of perforations per filmstrip, a perforator capable of making a variable number of perforations at a time in a long continuous film, and a transporting device for transporting said film by a length dependent on the designated number number of perforations, whereby the transport of the film needs only be interrupted once per filmstrip.
- This object is solved by the filmstrip manufacturing apparatus according to
claim 1. - The film length adjusting device sets the length of the continuous film from a cut position of the cutter to a punching position of the die set device into a value a number M of times as long as the unit length, plus a length from a first end of each filmstrip, which is to be cut at the cut position, to a first perforation to be made at the punching position in each filmstrip.
- In a preferred embodiment of the present invention a filmstrip manufacturing apparatus is provided which has a side-printer between a stationary perforator and a stationary cutter, the side-printer being capable of printing data on the long film along one or both lateral sides of recording sections of individual filmstrips to be made from the long film, whereby even with side-printing the transport of the film needs only be interrupted once per filmstrip.
- According to this preferred embodiment, a suction drum is disposed between the die set and the cutter, to transport the film toward the cutter by a unit length after each die-punching, and a pair of feed rollers are disposed between the cutter and the suction drum, and one of the feed rollers has a larger diameter than the other. A side-printer is arranged to record data on the film at a peripheral position of the larger feed roller. In this way, it is possible to dispose the side-printer closer to the cutter enough to continue side-printing without intermediate stops in the recording section of each filmstrip. The distance between the cut position and the peripheral position for side-printing is preferably set equal or less than the length from the first end to the first perforation of each filmstrip.

-
- In Fig. 1, a filmstrip manufacturing apparatus is adapted to manufacture filmstrips in a format as shown in Fig. 2, wherein each
film exposure location 40 is designated by a perforation P. Thefilmstrip 5 has a length L1 which is variable depending on its film frame number N, i.e., the number of theframe exposure locations 40 to be provided in thefilmstrip 5. The perforations P1 to PN are disposed at constant intervals L2 in a recording section of eachindividual filmstrip 5. As shown by hatching, both lateral sides of thefilmstrip 5 serve as side-print zones 42. - A long continuous strip of
film 12 is fed from aroll 10 through adancer roller 13,sub-feed rollers 14, avacuum suction drum 15 and apass roller 16 into a die setdevice 45, like the apparatus shown in Fig. 13. The die setdevice 45 is constituted of first to third die sets 46, 47 and 48 which are aligned in continuity along a film transport path, and may be individually actuated. - As shown in Fig. 3, the first die set 46 is constituted of a
punch holder 46a having fifteenpunches 50 arranged at the same interval L2 as the perforations P1 to PN, a diesplate 46b having fifteen dies 51 arranged in correspondence with thepunches 50, and anair cylinder 46c for moving thepunch holder 46a downward. The second and third die sets 47 and 48 are each constituted of apunch holder punches 50 arranged at the same interval L2 as the perforations P1 to PN, a diesplate punches 50, and anair cylinder punch holder sets punches 50 and the dies 51 as well are spaced at the same interval L2 along the film transport path. - The die set
device 45 can make a series of perforations P1 to PN per one stroke of die-punching while selecting the film frame number N among three variations: 15-exposure, 25-exposure and 35-exposure formats. To make 15-exposure format filmstrips, only the first die set 46 is actuated. To make 25-exposure format filmstrips, the first and second die sets 46 and 47 are actuated simultaneously. For 35-exposure format filmstrips, all the three die sets 46 to 48 are simultaneously actuated. Since the diesplates punch holders plates punch holders 46a to 48a. - At a film exit of the die set
device 45 is disposed a filmlength adjusting mechanism 58 which is constituted ofpass rollers movable roller 56 mounted movable in a vertical direction inside achamber 55 which is disposed between thepass rollers vacuum suction drum 60 is disposed downstream of the filmlength adjusting mechanism 58, to transport thelong film 12 by a unit length which is predetermined in accordance with the film frame number N. Thesuction drum 60 sucks thelong film 12 to not-shown suction holes formed through a peripheral surface of thedrum 60. Thesuction drum 60 is driven by aservo motor 61, while anencoder 62 monitors the rotational amount of thesuction drum 60 through theservo motor 61. - The
long film 12 is transported from thesuction drum 60 to acutter 28 through a pair offeed rollers suction drum 60. A side-printer 27 is disposed near thefeed roller 65 to print film data as character data and bar code data along both lateral sides of thelong film 12 in the side-print zone 42 of theindividual filmstrips 5 to be formed from thelong film 12. Thecutter 28 cuts off theindividual filmstrips 5 from thelong film 12 at the variable length L1. Thecutter 28 has first and second knife edges 28a and 28b respectively for cutting a trailingend 6 of afilms trip 5 and aleading end 7 of an adjacentpreceding filmstrip 5 in thelong film 12. - Fig. 5 shows the relationship between the
long film 12 and twoadjacent filmstrips 5a and 5b to be cut off therefrom. When thecutter 28 make a stroke, aleading end 7a of the preceding filmstrip 5a and a trailingend 6b of thefollowing filmstrip 5b are simultaneously cut by theedges cutter 28, respectively. Since a trailing end 6a of the preceding filmstrip 5a has been cut at the preceding cutting stroke, the filmstrip 5a is cut off from thefilm 12 when itsleading end 7a is cut by theedge 28b. - In correspondence with the spacing between the knife edges 28a and 28b, a blank having a constant length L5 is provided between the
leading end 7a and the trailingend 6b. Accordingly, thefilm 12 is transported by a unit length L4 = L1 + L5 after each stroke of thecutter 28. Thecutter 28 preferably has a pair of punches in addition to the knife edges 28a and 28b to provide engaging holes 9 concurrently with cutting thelong film 12 intoindividual filmstrip 5, the engaging holes 9 being used to secure the trailingend 6 to a spool of a photographic film cassette. - The film
length adjusting mechanism 58 is adapted to adjust the length of thefilm 12 extending between a cut position B defined by theknife edge 28a of thecutter 28 and a punching position A defined by the leftmost punch and die 50a and 51a of the first die set 46 in Fig. 4. As shown in Figs. 6 and 7, themovable roller 56 is movably mounted to a supportingblock 70 which is movable along a pair ofvertical guide shaft 71. - A
timing belt 72 is securely connected to the supportingblock 70, and is suspended between teethedpulleys pulley 74 is driven by aservo motor 75 to move the supportingblock 70 and thus themovable roller 56 in the vertical direction. Anencoder 76 is connected to theother pulley 73 to detect position of themovable roller 56. Themovable roller 56 may be stopped at one of three predetermined positions X, Y and X, as is shown in Fig. 4, such that the length of thefilm 12 extending from the cut position B to the punching position A, hereinafter referred to as a film buffer length, is set at a value determined based on the unit length L4 for the designated kind of filmstrip, and a film trailer length L3 as well. The film trailer length L3 is the length from the trailingend 6 to a first perforation P1 of theindividual filmstrip 5, which is to be formed by the die and punch 50a and 51b at the punching position A. - In other words, when the
film 12 stops to be cut by thecutter 28, the length of thefilm 12 between a trailingend 6 being positioned at the cut position B, on one hand, and a trailingend 6 of afilmstrip 5 being positioned in the die setdevice 45, on the other hand, is set at a value an integral number M of times as long as the unit length L4 for the designated kind filmstrips. Accordingly, it is possible to actuate the die setdevice 45 and thecutter 28 in synchronism with each other each time thefilm 12 stops after being transported by the unit length L4. - In this embodiment, the
movable roller 56 is moved in the position X when manufacturing 15-exposure filmstrips from thefilm 12, to set the film buffer length M times as long as a unit length L4a for 15-exposure filmstrip, plus the film trailer length L3, that is, L4a x M + L3. When manufacturing 25-exposure filmstrips, themovable roller 56 is moved in the position Y, so that the film buffer length becomes M times as long as a unit length L4b for 25-exposure filmstrip, plus the film trailer length L3, that is, L4b x M + L3. When themovable roller 56 moves in the position Z, the film buffer length is M times as long as a unit length L4c for 35-exposure filmstrip, plus the film trailer length L3, that is, L4c x M + L3. The positioning of themovable roller 56 may be manually executed, so theservo motor 75 is dispensable. - Alternatively, it is possible to assign the position Z of the
movable roller 56 to the 15-exposure filmstrips, and the position Y to the 25-exposure filmstrips by using a larger integral number M + α as a factor to define the film buffer length for the 15-exposure filmstrips than an integral number M which is used as a factor to define the film buffer length for the 25-exposure filmstrips. In that case, the position X may be assigned to the 35-exposure filmstrips by using a smaller integral number M - α as a factor to define the film buffer length for the 35-exposure filmstrips. - The
feed rollers suction drum 60 so thefilm 12 may not be loosened. In order to ensure a constant distance from the side-printer 27 to thefilm 12 at the side-print position C, the side-print position C is set in a peripheral position of thefeed roller 65 where thefilm 12 is in tight contact with theroller 65. Thefeed roller 65 has a larger diameter than theother feed roller 64, so as to permit the tight contact. In order to tense thefilm 12 at the side-print position, it is possible to set the circumferential speed of thefeed rollers suction drum 60. - Since the
feed rollers suction drum 60, the side-printer 27 may be disposed closer to thecutter 28, as is shown in Fig. 8, compared with the case shown in Fig. 14. Accordingly, it is possible to make the distance between the side-print position C and the cut position B equal to or less than the film trailer length L3, as is shown in Fig. 2. The distance between the positions B and C may be about 50 mm to 100 mm, preferably 50 mm to 70 mm, and more preferably 60 mm to 70 mm. In this way, when thefilm 12 stops to be cut by thecutter 28, the print position C is located before or at the first perforation P1 defining the start or front end of the recording section in the film transporting direction. Accordingly, side-printing can be performed without intermediate stops through the recording section of each individual filmstrip. - It is preferable to provide
pass rollers pass roller 54, so that the photosensitive emulsion surface of thefilm 12 will not contact thesuction drum 60. This embodiment prevents the photosensitive emulsion surface of thefilm 12 from being scratched or damaged by sucking. - The operation of the above-described apparatus is controlled by a
controller 80, as shown in Fig. 10. Aconsole 81 serves as an input device for the operator to enter the film frame number N of the filmstrips to be manufactured. In correspondence with the entered film frame number N, thecontroller 80 selectively drives theair cylinders - Thereafter, the
controller 80 drives theservo motor 61 to rotate thesuction drum 60 to transport thefilm 12 by the unit length L4, which is determined in accordance with the film frame number N, while monitoring output signals from theencoder 62. Thecontroller 80 concurrently drives theservo motor 75 to move themovable roller 56 into one of the three positions X, Y and Z in accordance with the film frame number N, while monitoring output signal from theencoder 76. Thecontroller 80 also actuates the side-printer 27 and thecutter 28 with respect to the output signal from theencoder 62 under the control of thecontroller 80. Thecontroller 80 sequentially controls the respective parts in accordance with a program stored in aROM 83. - The above-described apparatus operates as follows:
- After loading the
roll 10, the operator enters the film frame number N, e.g., N = 15, through the console. Then, thecontroller 80 moves themovable roller 56 in the position X through theservo motor 75, and rotate thesuction drum 60, thefeed rollers servo motor 61 to transport thefilm 12 toward thecutter 28. When thefilm 12 is positioned in the die setdevice 45 by transporting the film 12 a certain amount from theroll 10, thecontroller 80 actuates the first die set 46 through theair cylinder 46c to make fifteen perforations P1 to P15 through thefilm 12. Simultaneously, thecutter 28 is actuated to cut a portion of thefilm 12 where no perforation is made. Thereafter, thefilm 12 is transported by the unit length L4a for 15-exposure filmstrip. - When die-punching and transporting of the
film 12 by the unit length L4a are repeated a number of times corresponding to the film buffer length provided in the position X of themovable roller 56, the trailingend 6 of thefilmstrip 5 having the fifteen perforations in its recording section is placed in the cut position B. Simultaneously therewith, the next recording section to be perforated is placed between thepunch holder 46a and the diesplate 46b of the first die set 46. Then, thecontroller 80 stops transporting thefilm 12, and actuates thecutter 28 and the first die set 46 at the same time. Thereafter thefilm 12 is transported by the unit length L4a, and then the first die set 46 is actuated and, simultaneously, thecutter 28 is actuated to cut the trailingend 6 of thenext filmstrip 5 and theleading end 7 of thefilmstrip 5 whose trailingend 6 has previously been cut. As a result, thefilmstrip 5 with fifteen perforations is cut off thefilm 12 into an individual 15-exposure filmstrip. In this way, die-punching and cutting are performed in synchronism with each other. - While the
film 12 is transported by the unit length L4a after each cutting, the side-printer 27 starts printing when the front end of the recording section immediately after the first perforation P1 is located in the print position C, and continuously print data of 15-exposure filmstrip along the side-print zone 42 in the recording section. Preferably, the side-printer 27 is disposed relative to thecutter 28 such that the side-printer 27 can start printing immediately after the start of film transport. - When changing the film frame number N, e.g., to N = 25, the operator enters a stop signal and the film frame number N = 25 through the console. Then, the
controller 80 stops activating the die setdevice 45, the side-printer and thecutter 28 after thefilm 12 is transported by the unit length L4a for 15-exposure filmstrip following a die-punching of the first die set 46. Thereafter, themovable roller 56 is moved to the position Y to adjust the film buffer length between the cut position B and the punching position A to the unit length L4b for 25-exposure filmstrip. - Then, the first and second die sets 46 and 47 are simultaneously actuated to make twenty-five perforations P1 to P25 at a time through the
film 12 and, thereafter, thesuction drum 60 is driven to transport thefilm 12 by the unit length L4b for 25-exposure filmstrip. Since the leading end and the trailing end of two adjacent filmstrips having fifteen perforations P1 to P15 formed therethrough are cut by thecutter 28 in synchronism with the die-punching of the first and second die sets 46 and 47, the preceding one of the two filmstrips is cut off thefilm 12 into an individual 15-exposure filmstrip. But the leading end of the following filmstrip is transported farther than thecutter 28 as a result of the rotation of thesuction drum 60 by the unit length L4b for 25-exposure filmstrip. - Accordingly, defective filmstrips will be produced until the leading end of the filmstrip having twenty-five perforations P1 to P25 reaches the
cutter 28. To minimize the number of defective filmstrips at the film frame number change, it is preferable to determine the film buffer length to be L4 + L3 for any film frame number N, by selecting a factor "1" to multiply the unit length L4 in the above-described definition. In this way, merely a defective filmstrip will be produced at each film frame number change. - Thereafter, die-punching of the first and second die sets 46 and 47 and cutting of the
cutter 28 are repeated in synchronism with each other, and the side-printer 27 prints data of 25-exposure filmstrip along the side-print zone 42 while thefilm 12 is transported by the unit length L4b after each die-punching, in the same way as above, to produce 25-exposure filmstrips. - When the operator designates the film frame number N = 35, the
movable roller 56 is moved to the position Z to adjust the film buffer length to the unit length L4c for 35-exposure filmstrip. Then, the first to third die sets 46 to 48 are simultaneously actuated to make thirty-five perforations P1 to P35 at a time. Thereafter, thesuction drum 60 is driven to transport thefilm 12 by the unit length L4c, while the side-printer 27 prints data of 35-exposure filmstrip along the side-print zone 42. The same operation is repeated to produce 35-exposure filmstrips in continuous succession. - Although the above-described embodiment relates to a case where a single perforation is provided in association with each frame exposure location, the present invention is applicable to a case where a pair of perforations P1a and P1b; P2a and P2b; ... PNa and PNb are provided for each frame exposure location, as is shown in Fig. 11. Two perforations for assigning longitudinal ends of each frame exposure location facilitate more accurate positioning of the frame exposure location in the exposure aperture of the camera. It is also possible to dispose a pair of perforations on opposite lateral sides of each frame exposure location.
- Although the
air cylinders controller 80 for each die-punching stroke of the associated die sets 46 to 48, it is also possible to provide acam 90 and alever 91, as is shown in Fig. 12, for actuation of eachpunch holder 93. In this embodiment, the lowermost position of thepunch holder 93 in the die-punching stroke is changed over by anair cylinder 92 connected to thepunch holder 93, between an active position and an inactive position. Thecam 90 is connected to theair cylinder 92 through thelever 91. Thelever 91 has acam follower 95 at its one end, thecam follower 95 being always contacted against the cam surface of thecam 90, and is connected to theair cylinder 92 at the opposite end, with itsfulcrum 94 disposed in an intermediate position. - Accordingly, one rotation of the
cam 90 causes one stroke of thepunch holder 93. When the lowermost position of thepunch holder 93 in the stroke is set in the inactive position by theair cylinder 92, thepunch holder 93 cannot perforate thefilm 12 placed on a dies plate 96. Though Fig. 12 shows only onepunch holder 93, a plurality ofsuch punch holders 93 are disposed along thefilm 12, and only thosepunch holders 93 which are set in the active position by the associatedair cylinders 92 can effect die-punching by one stroke. This embodiment is suitable for faster die-punching operation. - Although the
cam 90 and thelever 91 are provided for each die set, and are actuated in synchronism with one another in the above-embodiment, it is possible to actuate a plurality of punch holders with air cylinders by a single cam and a lever. - The present invention is not only applicable to manufacturing photographic filmstrips, but also to manufacturing other kinds of strips or webs from a long strip of resin film or paper.
- Thus, the present invention should not be limited to the embodiments shown in the drawings, but on the contrary, various modifications may be possible without departing from the scope of the appended claims.
