Definitions
- the present invention relates to an automatic assembling method, and more particularly to a method of automatically assembling a photographic film cassette, or the like, and an apparatus for practicing the method.
- a known 135 photographic film cassette has a cassette shell constituted of a cylindrical body formed of a thin metal sheet and two caps fitted thereon.
- the cassette shell has a spool contained therein on which photographic film is wound in a form of a roll.
- To assemble this photographic film cassette several methods are known.
- U.S. Pat. No. 4,614,019 (corresponding to Japanese Patent Publication No. 2-691) discloses a process of winding the photographic film on the spool, and then assembling the cassette in a darkroom:
- U.S. Pat. No. 4,080,711 discloses a process of bringing the assembled cassette shell into the darkroom, disassembling the cassette shell for insertion of the photographic film, inserting the photographic film wound on the spool, and then assembling the cassette shell.
- U.S. Pat. Nos. 4,834,306, 4,846,418 and European Publication EP-A2 0 406 815 each disclose a photographic film cassette in which a cassette shell is constituted of parts formed from resin, and rotation of a spool causes a leader of the photographic film to exit to the outside of the cassette.
- a leader-advancing cassette is different from conventional photographic film cassettes because the leader of the photographic film is fully contained within the cassette both before exposure to ambient light, and in that the cassette is easily handled.
- Such a leader-advancing cassette includes elements not utilized in conventional cassettes.
- a light-shielding shutter member may be mounted openably in a photographic film passage port of this type of film cassette for protecting the inside from ambient light.
- a visual indicator member may be incorporated in such a cassette, to appear externally for indicating the exposed condition of the photographic film.
- production of such a leader-advancing cassette has many inherent problems due to the increase in the number of the parts. Particularly when the cassette shells must be assembled or disassembled in a darkroom, the assembling operation is so complicated that production efficiency is difficult to increase. In such a case, even an automated assembling machine does not reliably increase production efficiency.
- a constant tact intermittent transport linear base machine for moving an endless conveyor member such as a belt or a chain periodically by a constant amount, is known, for example, from Japanese Patent Laid-open Publication 4-209121, wherein pallets are secured to the endless conveyor member.
- a constant tact intermittent transport linear base machine if positions of the pallets get out of order because of jamming of the works, stop positions of the pallets must be readjusted to restore the accuracy of assemblage. Readjustment requires a great deal of time so that the efficiency of the assembly process decreases.
- an object of the present invention is to provide an automatic assembling method, and an apparatus for that method, which enables a high efficiency assembly operation, even when a secondary assembly must be assembled into a primary assembly in a primary assembling process, while the secondary assembly is assembled in an independent secondary assembling process.
- Another object is to provide an automatic assembling apparatus which uses a constant tact intermittent transport linear base machine, but eliminates deviation of pallets and trouble in decoupling and coupling of the pallet being conveyed at short intervals.
- a further object of the present invention is to provide an automatic assembling method for assembling a cassette shell of a film cassette inclusive of a spool assembly in a single assembling line.
- each of a plurality of integrally formed pallets has a secondary work holder and a primary work holder which are arranged in the same desired positions. Parts of a secondary assembly are sequentially fed to the secondary work holder and are assembled into the secondary assembly in the secondary work holder in each pallet during conveying the pallets. The secondary assembly and other parts of a primary assembly are sequentially fed to the primary work holder in each pallet during conveying the pallets.

Abstract
Description
- 1. Field of the Invention
- The present invention relates to an automatic assembling method, and more particularly to a method of automatically assembling a photographic film cassette, or the like, and an apparatus for practicing the method.
- 2. Description of the Related Art
- Photographic film of the 135 type, contained in a cassette, as among the most popular formats of photographic film. A known 135 photographic film cassette has a cassette shell constituted of a cylindrical body formed of a thin metal sheet and two caps fitted thereon. The cassette shell has a spool contained therein on which photographic film is wound in a form of a roll. To assemble this photographic film cassette, several methods are known. For example, U.S. Pat. No. 4,614,019 (corresponding to Japanese Patent Publication No. 2-691) discloses a process of winding the photographic film on the spool, and then assembling the cassette in a darkroom: U.S. Pat. No. 4,080,711 (corresponding to Japanese Patent Publication No. 60-48748) discloses a process of bringing the assembled cassette shell into the darkroom, disassembling the cassette shell for insertion of the photographic film, inserting the photographic film wound on the spool, and then assembling the cassette shell.
- U.S. Pat. Nos. 4,834,306, 4,846,418 and European Publication EP-A2 0 406 815 (corresponding to Japanese Patent Laid-open Publication No. 3-37645), each disclose a photographic film cassette in which a cassette shell is constituted of parts formed from resin, and rotation of a spool causes a leader of the photographic film to exit to the outside of the cassette. Such a leader-advancing cassette is different from conventional photographic film cassettes because the leader of the photographic film is fully contained within the cassette both before exposure to ambient light, and in that the cassette is easily handled.
- Such a leader-advancing cassette includes elements not utilized in conventional cassettes. As disclosed, for example, in U.S. Pat. No. 4,834,306 (corresponding to Japanese Patent Laid-open Publication No. 1-306845) and U.S. Pat. No. 5,049,912, a light-shielding shutter member may be mounted openably in a photographic film passage port of this type of film cassette for protecting the inside from ambient light. Or a visual indicator member may be incorporated in such a cassette, to appear externally for indicating the exposed condition of the photographic film. However, production of such a leader-advancing cassette has many inherent problems due to the increase in the number of the parts. Particularly when the cassette shells must be assembled or disassembled in a darkroom, the assembling operation is so complicated that production efficiency is difficult to increase. In such a case, even an automated assembling machine does not reliably increase production efficiency.
- The problems are more complicated for a photographic film cassette wherein a spool is an assembly constituted of a pair of flanges force-fitted of the spool core, and the spool assembly is mounted in one shell half before the other shell half is joined therewith. This is because an independent assembling process for assembling the spool assembly is necessary before a primary assembling process of the film cassette, wherein the spool assembly, the shutter plate and other parts are mounted into the cassette. In such a case, there are at least two assembling lines and at least a transfer conveyor for connecting the two lines. Therefore, the mechanism of the conventional system are complicated. The need for transferring works between the lines increases the occurrence of problems. The same problem as described above could generally arise in other automatic assembling systems, where a secondary assembly should be incorporated into a primary assembly.
- On the other hand, a constant tact intermittent transport linear base machine for moving an endless conveyor member such as a belt or a chain periodically by a constant amount, is known, for example, from Japanese Patent Laid-open Publication 4-209121, wherein pallets are secured to the endless conveyor member. When assembling works by using such a constant tact intermittent transport linear base machine, if positions of the pallets get out of order because of jamming of the works, stop positions of the pallets must be readjusted to restore the accuracy of assemblage. Readjustment requires a great deal of time so that the efficiency of the assembly process decreases.
- Conventional constant tact intermittent linear base machines further have a problem in that the pallet must be decoupled from and coupled to the conveyor to be fed back to the assembling line, through a feed back line, after the completion of assemblage on that pallet. The decoupling-coupling operations often cause problems especially in a high speed tact system.
- In view of the above problems, an object of the present invention is to provide an automatic assembling method, and an apparatus for that method, which enables a high efficiency assembly operation, even when a secondary assembly must be assembled into a primary assembly in a primary assembling process, while the secondary assembly is assembled in an independent secondary assembling process.
- Another object is to provide an automatic assembling apparatus which uses a constant tact intermittent transport linear base machine, but eliminates deviation of pallets and trouble in decoupling and coupling of the pallet being conveyed at short intervals.
- A further object of the present invention is to provide an automatic assembling method for assembling a cassette shell of a film cassette inclusive of a spool assembly in a single assembling line.
- To achieve the above and other objects, according to the present invention, each of a plurality of integrally formed pallets has a secondary work holder and a primary work holder which are arranged in the same desired positions. Parts of a secondary assembly are sequentially fed to the secondary work holder and are assembled into the secondary assembly in the secondary work holder in each pallet during conveying the pallets. The secondary assembly and other parts of a primary assembly are sequentially fed to the primary work holder in each pallet during conveying the pallets.
- Therefore, it is unnecessary to provide a secondary assembling line for assembling the secondary assembly separately from a primary assembling line for the primary assembly. Because of the single assembling line, it is unnecessary to provide interconnecting devices such as a synchronizing device and a buffer conveyor, which would otherwise be necessary for connecting the primary and secondary assembling lines.
- Other objects and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments when read in connection with the accompanying drawings, wherein like reference numerals designates like or corresponding parts throughout the several views, and wherein:
- FIG. 1 is an exploded perspective view illustrating an example of a leader-advancing film cassette;
- FIG. 2 is an explanatory perspective view of a pallet utilized for assembling a spool assembly and a cassette shell of the leader-advancing film cassette shown in FIG. 1, according to a preferred embodiment of the apparatus;
- FIG. 3 is a schematic side view of a pallet conveyor;
- FIG. 4 is a schematic top plan view illustrating the pallet conveyor shown in FIG. 3 and an assembling unit of the preferred embodiment;
- FIG. 5 is an enlarged top plan view of the pallet positioned on the pallet conveyor by a pallet positioning unit of the preferred embodiment; and
- FIG. 6 is a top view of the positioning unit of FIG. 5.
- FIG. 1 illustrates a photographic film cassette to be assembled by a cassette assembling apparatus according to a preferred embodiment of the present invention as shown in FIGS.2-7. A
spool assembly 12 is contained in acassette shell 10 constituted of a pair ofshell halves 7 and 8 molded from resin.Ridges 15 are formed on the inside of theshell halves 7 and 8. Whenphotographic film 24 is wound around thespool assembly 12 and contained within a chamber defined between theshell halves 7 and 8, theridges 15 are in contact with the outermost turn of thephotographic film 24 to prevent the roll of thephotographic film 24 from loosening. When thespool assembly 12 is rotated in the direction to unwind thefilm 24, clockwise in FIG. 1, the roll of thephotographic film 24 is also rotated clockwise. Aseparator claw 17 is formed inside of shell half 8. During rotation of the roll of thephotographic film 24, a leading end of the photographic film abuts on theseparator claw 17, which separates the leading end from the roll of thefilm 24. -
Port walls 7 a and 8 a are formed on theshell halves 7 and 8, respectively. When theshell halves 7 and 8 are joined together, theport walls 7 a and 8 a define a photographicfilm passage port 19. Ashutter 14 is rotatably mounted in a cylindrical cavity formed by a pair ofsemi-cylindrical recesses 23 formed inside theport walls 7 a and 8 a. Both ends of theshutter 14 are provided withrotary shaft portions 14 a to be borne between theport walls 7 a and 8 a, so that theshutter 14 is rotatable about an axis which is parallel to thespool assembly 12. An end of theshaft portions 14 a has a key 16, which extends through a hole formed in thecassette shell 10. When anopener member 18 is fitted on the key 16 and rotates the key 16, theshutter 14 is rotated between positions of blocking and opening afilm passage 19 formed between theport walls 7 a and 8 a. - The
spool assembly 12 is constituted of aspool core 12 a and a pair offlanges 12 b fitted on thespool core 12 a. Thephotographic film 24 is wound on thespool core 12 a between theflanges 12 b. Both ends of thespool assembly 12 extend through faces of thecassette shell 10, and are provided withkeys 13. Thekeys 13 are used for engagement with a drive member for rotating thespool assembly 12 in a known manner. Anotch 13 a is formed in one of thekeys 13, for externally indicating the rotational position of thespool assembly 12. This indication is necessary for inserting thefilm trailer 24 a into aslot 20 formed along thespool core 12 a. - Inside the
slot 20 are arranged two retainingclaws 21 and a slip-preventive ridge which is not shown but extends in the direction opposite to, and are disposed between, the retainingclaws 21. The right side of theslot 20 is adapted to receive thefilm trailer 24 a. Thefilm trailer 24 a has a pair of retainingholes 25 formed therein, which are engageable with the retainingclaws 21. The slip-preventing ridge presses the trailer end 24 a in the direction opposite to projecting of the retainingclaws 21, so that theholes 25 are maintained engaged with the retainingclaws 21, even if a force tending to pull thephotographic film 24 from theslot 20 should be applied to thetrailer 24 a. Thetrailer 24 a is further provided with a pair of pick-upholes 26 which are disposed outside the pair of retainingholes 25 in the lateral direction of thefilm 24. The pickup holes 26 are used for inserting thefilm trailer 24 a into theslot 20 with a jig. - FIG. 2 illustrates a
pallet 30 utilized for assembling the above-described photographic film cassette. Thepallet 30 has ashell holder 31 for holding the one shell half 8, hereinafter referred to as a lower shell half 8, and aspool holder 32 for holding thespool assembly 12. Thepallet 30 also has a pair of positioning pins 33 utilized for positioning thepallet 30 in respective assembling stations, as will be described in detail below. - The
spool holder 32 has aflange accepting recess 32 a and a spoolcore accepting hole 32 b formed therein. After theflange 12 b is positioned in therecess 32 a, thespool core 12 a is inserted in thehole 32 b, while force-fitting thespool core 12 a through theflange 12 b. Thereafter, theother flange 12 c is force fitted on the opposite upper end of thespool core 12 a, completing thespool assembly 12. Theshell holder 31 is secured to thepallet 30, and has arecess 31 a formed therein, whose inside surface corresponds to the outward form of the lower shell half 8. After the lower shell half 8 is placed in theshell holder 31, thespool assembly 12 is pulled off thespool holder 32 and is placed in the lower shell half 8. The other orupper shell half 7 is then joined to the lower shell half 8 to complete thecassette shell 10. Finally, thecomplete cassette shell 10 is removed from theshell holder 31. - The above-described spool assembling operations and the assembling operations for the
cassette shell 10 are performed by an assembling unit constituted of a series of pick-and-place devices, as will be described below with respect to a preferred embodiment. - The
pallets 30 are successively conveyed by apallet conveyer 40, for example, as shown in FIGS. 3 and 4. Thepallet conveyer 40 is constituted of anendless belt 41 circulating in a horizontal attitude around pulleys 42 and 43 whoserotary shafts endless belt 41 has a plurality ofpallet spacers 44 mounted on the bearing surface thereof. The pallet spacers 44 are spaced equally in the longitudinal direction of thebelt 41 by a distance slightly longer than the length of thepallets 30. The pallet spacers 44 are rectangular ridges projecting from the bearing surface of thebelt 41, which confine thepallets 30 at the leading and trailing ends thereof in the conveying direction or the longitudinal direction of thepallets 30 during the conveying. Instead of therectangular ridges 44, pallet spacers may be formed by pins which are adopted to be loosely engaged in holes which may be formed in the bottom of pallets. - As shown in FIG. 4, the
shaft 43 a of thepuller 43 is coupled to a constantangle rotation unit 45 for controlling constant tact intermittent transport of theendless belt 41. Theunit 45 is driven by acam shaft 46 to cause thepulley 43 to rotate intermittently by through a constant incremental angel. Thereby, thepallets 30 are periodically advanced by a constant amount through theendless belt 41. Thecam shaft 46 is driven by adrive motor 48 through atransmission belt 47. - A plurality of pick-and-
place devices 50 are disposed along an upper path of theendless belt 41 of thepallet conveyer 40 in every other stop position of thepallets 40, to assemble the respective parts of thecassette shell 10, such as the shell halves 7 and 8, theshutter plate 14, thespool core 12 a and theflanges holders pallets 30. In each pick-and-place device 50, a designated part is picked up by one end of anarm 50 a, and simultaneously the same part is mounted on an appropriate place by the other end of theart 50 a. - A pick-and-
place device 52, which is disposed at a last position in the pallet conveying direction, removes thecomplete cassette shell 10 from theshell holder 31 and discharged it from the assembling line, that is, the upper path of theendless belt 41. The pick-and-place device 52 also has anarm 52 a which operates in the same way as thearms 50 a. The pick-and-place devices cam shaft 46 throughcam members -
Parts feeders 51 are disposed beside the pick-and-pace devices 50, each for feeding the designated parts one after another to be associated pick-and-place device 50. Of course, no parts feeder is allocated to one of the pick-and-place devices 50 which serves to mount thecomplete spool assembly 12 into the lower shell half 8. Hereinafter, the stop positions of thepallets 30 corresponding to the pick-and-place devices - As shown in FIG. 5,
pallet guide fences endless belt 41 along the upper path of thebelt 41, to limit lateral movement of thepallets 30 on theendless belt 41. Thepallet guide fences guide base 55, on which theendless belt 41 is guided in the horizontal state. Along a lower path of theendless belt 41 and around thepulleys anti-drop guide rails pallets 30 from dropping off theendless belt 41, as is shown in FIG. 5. Theanti-drop guide rails guide base 58. Theanti-drop guide rails 56 are constituted of a pair of fences disposed along the lateral sides of theendless belt 41 and havinghooks 56 a which catch the lateral edges of thepallets 30. Therefore, thepallets 30 may not drop down in spite of their weight. Theanti-drop guide rails 57 have the same construction and function as the anti-drop guide rails 56. The lower path of theendless belt 41 functions as a feed back line for feedingempty pallets 30 back to the assembling line. - Because the
pallets 30 are not secured to theendless belt 41, but are removably held by thepallet spacers 44 and theguide fences pallets 30 are each independently adjustable in individual assembling stations. By providing theanti-drop guide rails pallets 30 may be conveyed cyclically on theendless belt 41 without the need for decoupling thepallets 30 from theendless belt 41 and then coupling the same to theendless belt 41. Therefore, a high speed of transport or short interval between transport steps may be achieved with reliability. - As shown in FIGS. 5 and 6, a
positioning unit 60 is disposed in association with each pick-and-place devices positioning unit 60 has alateral positioning plate 61 and alongitudinal positioning plate 62. Thelateral positioning plate 61 is mounted to aguide plate 63 to be movable in the lateral direction of thepallet 30. Thelateral positioning plate 61 is secured to abracket 65 having acam follower 66 secured thereto. Thecam follower 66 contacts aneccentric cam 67, and acoiled spring 68 suspended between thebracket 65 and theguide 63 urges thecam follower 66 toward thecam 67. Accordingly, thelateral positioning plate 61 is urged away from thepallet 30. Thecam 67 is driven through thecam shaft 46 to rotate at an angle of 180 degrees in each step. - The
longitudinal positioning plate 62 is mounted to a guide plate 70 to be movable in the lateral direction of thepallet 30. Thelateral positioning plate 62 is secured to abracket 71 having acam follower 72 secured thereto. Thecam follower 72 contacts aneccentric cam 73, and acoiled spring 75 suspended between thebracket 71 and the guide plate 70 urges thecam follower 72 toward thecam 73. Accordingly,longitudinal positioning plate 62 is urged toward thepallet 30. Theeccentric cam 73 is also driven through thecan shaft 46 to rotate at an angle of 180 degrees in each step. - The
longitudinal positioning plate 62 has a pair ofsymmetrical slopes 76 spaced from each other in the longitudinal direction of theendless belt 41, such that theslopes 76 are brought into tangential contact with the positioning pins 33 of thepallet 30 to push thepins 33 toward each other when thelongitudinal positioning plate 62 is moved toward thepallet 30. - While the
pallets 30 are conveyed on theendless belt 41 by one step, that is, from one stop position to the next, thecam shaft 46 causes theeccentric cams pallets 30 are stopped at the respective assembling stations S1 to S8, theeccentric cams cam 67 pushes thecam follower 66 to move thebracket 65 against the force of thespring 68 and thus move thelateral positioning plate 61 toward thepallet 30 into a predetermined position, as is shown by solid line in FIG. 6. Concurrently, thelongitudinal positioning plate 62 is moved toward thepallet 30 under the force of thespring 75, as is shown by solid line in FIG. 6. Thereby, thepallet 30 is pushed against thelateral positioning plate 61, to be positioned in the lateral direction. - Because the positioning pins33 are pushed toward each other by the
slopes 76 while thelongitudinal positioning plate 62 is moved toward thepallet 30, thepins 33 are centered on the symmetrical axis of theslopes 75, so that thepallet 30 is positioned in the longitudinal direction. While thepallets 30 are advanced from one assembling station to another, theeccentric cams positioning plates pallet 30, as is indicated by arrows and phantom lines in FIG. 6. - The assembling operations of the
cassette shell 10 are performed, for example, in the following sequence. - The
respective pallets 30 are periodically advanced by thepallet conveyer 40 to be seriatim fed to the respective assembling stations S1 to S8, as is shown in FIGS. 3 and 4. In the first assembling station S1, the pick-and-place device 50 mounts the lower shell half 8 in theshell holder 31 of thepallet 30, as is shown in FIG. 2. Next, theshutter 14 is mounted in thesemi-cylindrical recess 23 of the lower shell half 8 in the second assembling station S2. In the third assembling station S3, theflange 12 b is set in theflange accepting recess 32 a of thespool holder 32 of thepallet 30. In the fourth assembling station S4, thespool core 12 a is fitted in the spoolcore accepting hole 32 b of thespool holder 32, thereby force-fitting theflange 12 b on one end of thespool core 12 a. In the fifth assembling station S5, theflange 12 c is fitted on the other end of thespool core 12 a which is still fitted in the spoolcore accepting hole 32 b. In the sixth assembling station S6, thecomplete spool assembly 12 is pulled off thespool holder 32 and mounted in the lower shell half 8 held in theshell holder 31. In the seventh assembling station S7, the pick-and-place device 50 joins theupper shell half 7 to the lower shell half, through ultrasonic welding or the like, 8 in theshell holder 31, to complete thecassette shell 10. In the last station S8, the pick-and-place unit 52 removes thecassette shell 10 from theshell holder 31 to transfer theshell 10 to another line. Thepallet conveyer 40 feeds theempty pallet 30 back to the first assembling station S1. The control and activation of various functions with pick-and-place units 52 is well known. - In alternative, it is possible to first perform assembling of the
spool assembly 12 in the side of thespool holder 32, and thereafter start assembling in the side of theshell holder 31. The flanges may be secured to the spool core through hooking, caulking, cementing or the like. It is, of course, possible to provide more than either stations so as to assemble a cassette shell having a larger number of parts than the cassette shell shown in FIG. 1, such as disclosed in U.S. Pat. No. 5,049,912. - As described so far, according to the present invention, each pallet has a secondary work holder, such as a spool holder, besides a primary work holder, such as a shell holder, so that parts of a secondary assembly, such as a spool assembly, are sequentially assembled in the side of the secondary work holder, and parts of a primary assembly, such as a cassette shell, which includes the secondary assembly as one of its parts, are sequentially assembled in the primary work holder, while the pallet is conveyed along a single assembling line.
- Therefore, it is unnecessary to provide a secondary assembling line for assembling the secondary assembly separately from a primary assembling line for the primary assembly. Because of the single assembling line, it is also unnecessary to provide interconnecting devices such as a synchronizing device and a buffer conveyer, which would otherwise be necessary for connecting the primary and secondary assembling lines. Therefore, the assembling apparatus of the present invention may be simple in construction and facilitates increasing assembling speed and efficiency. The assembling apparatus of the present invention may also be constructed at reduced expense as it requires merely a single drive motor and a constant angle rotation unit for transporting pallets intermittently at a constant tact or pitch. It also requires merely one type of pallet. Moreover, malfunctions may be reduced because the need for handing the workpieces is reduced. The pallets of the preferred embodiment are integrally formed, i.e., are assembled from one or more pieces in a single unitary structure.
- While the present invention has been described with respect to a preferred embodiment for automatic assembling of the
cassette shell 10, the present invention is applicable to automatic assembling of any kind of article wherein a secondary assembly should be incorporated in a primary assembly. - Also, it will be apparent to one skilled in the art that various other modifications can be made to the disclosed embodiment without departing from the scope of the invention as defined by the appended claims.
