BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge assembling apparatus for assembling a cartridge comprising a drum plate and a cap for accommodating a photographic roll film, and more particularly to a cartridge assembling apparatus having an assembly chuck for holding the drum plate in a cylindrically rounded state.
[0002]
[Prior art]
The cartridge assembling device rolls a trunk plate formed in a pseudo-boat shape into a cylindrical shape, inserts a cap into one end of the rolled trunk plate, caulks the cap onto the trunk plate, and forms a spool on which the film is wound. It is an apparatus for assembling a cartridge by storing in a plate, inserting a cap into the open end of the barrel plate, and crimping the cap to the barrel plate. The cartridge assembling apparatus includes an assembly chuck that detachably holds the body plate in order to convey the body plate while maintaining a certain shape to each process unit in the apparatus.
[0003]
Referring to FIG. 8, the conventional assembly chuck is sandwiched by sandwiching the barrel plate 50 rounded into a substantially cylindrical shape from the bottom surface side of the cylindrical core bar 130 with the auxiliary metal fitting 160, and the straight portion 51 of the barrel plate. There is an adjustment guide 170 that adjusts a gap (port width 53) for taking out a film between the fold and the seam folding portion 52 to hold the straight portion 51 of the trunk plate.
[0004]
[Problems to be solved by the invention]
However, when the port width 53 is adjusted by the adjustment guide 170 as in the conventional assembly chuck, the port width 53 varies due to variations in the properties of the steel plate used for the body plate 50 (springback amount = SB value). There is a problem that the shape of the body plate 50 becomes unstable.
[0005]
Further, in the conventional assembly chuck, when the operating speed becomes high, it becomes impossible to hold the stable body plate, and the above problem becomes more remarkable. As a result, when the cap is caulked, it causes deformation of the cap or the body plate. Further, since the shape of the cartridge is separated from the perfect circle, local pressure is applied to the internal film, and there is a problem that the appearance of the film inserted as a final product is scratched. Furthermore, the gap between the end of the port width, the goby folded portion, and the straight portion becomes over-standard, and light enters the cartridge, causing the film to have poor light shielding properties.
[0006]
A first object of the present invention is to provide a cartridge assembly apparatus capable of stable holding even at a high speed.
[0007]
A second object of the present invention is to provide a cartridge assembly apparatus that can stabilize (homogenize) the shape of a cartridge even at high speed.

Next, the operation of the cartridge assembly apparatus according to the first embodiment will be described. FIG. 6 is a block diagram schematically illustrating the configuration of the cartridge assembly apparatus according to the first embodiment of the present invention.
[0032]
First, the boat-shaped trunk plate 50 is supplied from the trunk plate supply unit 2 to the rounding unit 3, and the boat-shaped trunk plate supplied in the rounding unit 3 is rounded into a substantially cylindrical shape.
[0033]
Next, the rounded body plate is conveyed from the rounding part 3 to the assembly chuck 20 stopped in the vicinity thereof through the body plate insertion part 9, and the body plate 50 is inserted into the assembly chuck 20 in the open state. When the assembly chuck 20 is closed, the body plate 50 is held in a state of being rounded into a cylindrical shape (see FIG. 2).
[0034]
Next, when the index plate 10 is rotated by one pitch and stopped at another stop position, the held barrel plate 50 has one end (the leading end side of the cored bar) of the barrel plate rounded at the cap insertion portion 4. The cap is inserted into (see FIG. 4). At this time, the assembly chuck 20 does not open and close.
[0035]
Next, when the index means 10 is rotated by one pitch and stops at another stop position, the caulking claw 90 is moved from the inner surface side of the outer peripheral portion 60a of the cap 60 to the caulking portion 5 of the body plate with the cap inserted. A single-open cartridge is manufactured by pressing against the stepped portion 20a and caulking the cap 60 to the body plate 50 (see FIG. 7). Also at this time, the assembly chuck 20 does not open and close.
[0036]
Next, in the manufactured single-open cartridge, when the index means 10 is rotated by one pitch and stopped at another stop position, the detection unit 6 monitors the engagement state of the cap and the trunk plate related to the single-open cartridge, It is detected whether the single-open cartridge is a non-defective product. Also at this time, the assembly chuck 20 does not open and close.
[0037]
Next, when the index means 10 rotates by one pitch and stops at another stop position, the assembly chuck 20 is opened in the non-defective product discharge section 7 and the detection result in the detection section 6 is detected. Based on this, the single-open cartridge according to the non-defective product is pressed by the discharge mechanism member 80 and discharged to the outside (see FIG. 5). If it is determined that the product is defective, the single-open cartridge relating to the defective product is not discharged.
[0038]
Next, when the index means 10 is rotated by one pitch and stopped at another stop position, the assembly chuck 20 remains open. However, when there is a single-open cartridge relating to a defective product, the defective product discharge unit 8 The single-open cartridge or the remaining product (only the cap, only the body plate) that has not been discharged by the non-defective product discharge unit 7 is pressed by the discharge mechanism member 80 and discharged to the outside (see FIG. 5).
[0039]
Next, when the index means 10 is rotated by one pitch and stopped at another stop position, the body plate rounded by the rounding portion 3 is inserted into the empty assembly chuck 20, and the above operation is repeated. Further, the operations of the respective process parts are performed in parallel, and a single-open cartridge is completed every time one pitch is rotated.
[0040]
【The invention's effect】
According to the present invention, since the entire outer peripheral surface of the body plate including the straight portion of the rounded body plate and the cylindrical surface is pressed by the assembly chuck, the cylindrical surface of the body plate is close to a perfect circle even under high speed. You can assemble a single-open cartridge. As a result, film scratches due to shape defects are almost eliminated.
[0041]
In addition, the angle formed by the line connecting the boundary between the cylindrical inner surface and the flat portion and the central axis with respect to the line connecting the central axis and the tip of the edge in the cross section in the closed state of the assembly chuck is constant. Easy to set up. Therefore, a constant port width can be obtained and the occurrence of light shielding failure can be reduced.
[0042]
Further, by preventing the shift of the port width, there is no time loss for adjustment, so that stable holding is possible even at high speed.
