Abstract
Abstract A film strip stacking device is provided for use in an order finishing station in conjunction with the negative cutter to accept film strips from the negative cutter which cuts the film into strips. The strips are collected into a stack which can then be loaded into a film sleeve prior to return to the customer. The film strip stacker of the present invention includes a channel divided into an upper and lower portion. The upper portion being adapted to receive initially the film from the negative cutter and including parallel rails movable to contact the film strip after it is cut and while it is in the upper portion of the channel and force the film to deform sufficiently to snap past the shelf members supporting the film into the lower portion of the channel. A pusher blade is movably mounted on the base of the film stacker and operable to contact an end of the film stack to push the stack out of the channel and into a film sleeve held in communication with the lower portion of the channel. The rails contact the edges of the film where there is no image to minimize the potential for damage to the image-containing portions of the film strip. Preferably, a sleeve opener mechanism is provided in conjunction with the stacker and operable in timed relation with the pusher blade to open the film sleeve to allow easy entry of the stack into the film sleeve as the pusher moves the stack from the second channel into the film sleeve. Also, the operation of the rails, the pusher blade, and the sleeve opener are all controlled in timed relation to the action of the knife in the negative cutter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
240 words
An apparatus for stacking strips of film comprising: a base; first and second channel-defining members mounted on said base in spaced parallel relationship to one another defining between them a channel; first and second shelf members rigidly mounted on and extending orthogonally from, respectively, said first and second channel-defining members and constructed and arranged to divide said channel into an upper portion and a lower portion, said first and second shelf members being spaced from one another; first and second elongate rails parallel to one another and spaced from one another, said rails movably mounted on said channel-defining members for movement from a first position in which said rails are located above, respectively, said first and second shelf members to a second position wherein said rails are located below said shelf members; pusher means movably mounted on said base for movement through said lower portion of said channel in a first direction from a first end to a second end; rail guide means associated with said rails and said channel-defining members for providing a component of motion of said rails in said first direction as said rails move from their first position to their second position; and control means associated with said rails and said pusher means for controlling the movement of said rails between said first and second positions and movement of said pusher means through said lower portion of said channel in a timed relationship to one another.
Claim 2
Independent Claim
240 words
An apparatus for stacking strips of film comprising: a base; first and second channel-defining members mounted on said base in spaced parallel relationship to one another defining between them a channel; first and second shelf members rigidly mounted on and extending orthogonally from, respectively, said first and second channel-defining members and constructed and arranged to divide said channel into an upper portion and a lower portion, said first and second shelf members being spaced from one another; first and second elongate rails parallel to one another and spaced from one another, said rails movably mounted on said channel-defining members for movement from a first position in which said rails are located above, respectively, said first and second shelf members to a second position wherein said rails are located below said shelf members; pusher means movably mounted on said base for movement through said lower portion of said channel in a first direction from a first end to a second end; rail guide means associated with said rails and said channel-defining members for providing a component of motion of said rails in said first direction as said rails move from their first position to their second position; and control means associated with said rails and said pusher means for controlling the movement of said rails between said first and second positions and movement of said pusher means through said lower portion of said channel in a timed relationship to one another.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 wherein said first and second channel defining members are chamfered at a first end.
Claim 4
Dependent Claim
76 words
The apparatus of claim 1 , wherein said rail guide means includes: a first guide pin mounted on said first and second channel-defining members transversely to said first channel; first and second drive links fixed at a first end thereof to said first guide pin and each pivotally attached at a second end thereof to, respectively, said first and second rails; and drive means fixed to said first guide pin for rotating said first guide pin.
Claim 5
Dependent Claim
38 words
The apparatus of claim 1, wherein said second channel-defining member is movably mounted on said base for movement in a direction transverse to the elongate dimension of said channel so as to vary the width of said channel.
Claim 6
Dependent Claim
47 words
The apparatus of claim 1 further including a chain mounted for movement along the elongate dimension of said channel, said pusher means including a blade rotatably mounted on said chain and further including a sprocket drivingly associated with said chain for moving said chain through said channel.
Claim 7
Dependent Claim
33 words
The apparatus of claim 1, wherein an upper surface of the second end of said first and second shelf members is curved in a direction away from the lower portion of said channel.
Claim 8
Independent Claim
267 words
An apparatus for stacking strips of film comprising: a base; first and second channel-defining members mounted on said base in spaced parallel relationship to one another defining between them a channel; first and second shelf members rigidly mounted on and extending orthogonally from, respectively, said first and second channel-defining members and constructed and arranged to divide said channel into an upper portion and a lower portion, said first and second shelf members being spaced from one another; first and second elongate rails parallel to one another and spaced from one another, said rails movably mounted on said channel-defining members for movement from a first position in which said rails are located above, respectively, said first and second shelf members to a second position wherein said rails are located below said shelf members; pusher means movably mounted on said base for movement through said lower portion of said channel in a first direction from a first end to a second end; control means associated with said rails and said pusher means for controlling the movement of said rails between said first and second positions and movement of said pusher means through said lower portion of said channel in a timed relationship to one another; a first guide pin mounted on said first and second channel-defining members transversely to said first channel; first and second drive links affixed at a first end thereof to said first guide pin and each pivotally attached at a second end thereof to, respectively, said first and second rails; and drive means fixed to said first guide pin for rotating said first guide pin.
