Abstract
Abstract This invention relates to a device for feeding, with the required orientation, substantially parallelepiped flat bodies comprising aspects of asymmetry, in particular cassettes for magnetic tapes. The device according to the invention comprises a vertically extending tubular loader of substantially rectangular cross-section for a plurality of stacked flat bodies, an expulsion member for transversely push out the lowest stacked body, a chute for collecting and conveying said lowest body towards an outlet seat provided with orientation sensing structure, and a tilting member located at the inlet end of said chute and driven by said sensing structure to cause tilting of the pushed out body on one side or the other according to the detected orientation of the same body.

Claim 1
Independent Claim
200 words
A device for feeding, with the required orientation, substantially parallelepiped flat bodies comprising aspects of asymmetry, in particular cassettes for magnetic tapes, comprising a tubular loader of substantially rectangular cross-section extending vertically in such a manner as to be able to receive a plurality of stacked and diversely orientated flat bodies to be fed, an expulsion member operable transversely to the loader to push out the lowest of the stacked bodies therefrom, a chute for collecting and conveying said flat body towards an outlet seat, sensor means for detecting the orientation of said flat body at the moment of its expulsion from the loader, and a tilting member inserted in the inlet end of said chute and driven by said sensor means, according to the detected orientation, towards one or other of its two working positions on opposite sides of the chute, in which it can receive the impact of the flat body introduced and allowed to fall into the chute, and consequently cause said flat body to tilt into a substantially vertical position on one side or the other according to the detected orientation, so as to make the orientation of said flat body constant at the chute outlet.
Claim 2
Independent Claim
200 words
A device for feeding, with the required orientation, substantially parallelepiped flat bodies comprising aspects of asymmetry, in particular cassettes for magnetic tapes, comprising a tubular loader of substantially rectangular cross-section extending vertically in such a manner as to be able to receive a plurality of stacked and diversely orientated flat bodies to be fed, an expulsion member operable transversely to the loader to push out the lowest of the stacked bodies therefrom, a chute for collecting and conveying said flat body towards an outlet seat, sensor means for detecting the orientation of said flat body at the moment of its expulsion from the loader, and a tilting member inserted in the inlet end of said chute and driven by said sensor means, according to the detected orientation, towards one or other of its two working positions on opposite sides of the chute, in which it can receive the impact of the flat body introduced and allowed to fall into the chute, and consequently cause said flat body to tilt into a substantially vertical position on one side or the other according to the detected orientation, so as to make the orientation of said flat body constant at the chute outlet.
Claim 3
Dependent Claim
26 words
A device as claimed in claim 1, wherein said loader is removably attached to a support structure so that it can be extracted and filled separately.
Claim 4
Dependent Claim
70 words
A device as claimed in claim 1, wherein said chute is formed from an upper inlet part of substantially enlarged rectangular cross-section, a middle part tapering downwards and a lower outlet part of substantially rectangular restricted cross-section, said upper part being provided with a lateral inlet aperture facing a lateral outlet aperture of the loader and housing said tilting member, and said lower part being open at its lower end.
Claim 5
Dependent Claim
62 words
A device as claimed in claim 3, wherein said tilting member is constituted by a fin rigid with an underlying rotatable pivot so that it can be controlled to assume one or other of two positions inclined towards opposite sides of the chute, said rotatable pivot being rotated by an electromagnet under the control of said sensor means for detecting the orientation.
Claim 6
Dependent Claim
72 words
A device as claimed in claim 1 for feeding magnetic tape cassettes with the required orientation, wherein said sensor means for detecting the orientation comprise a pair of opposing photoelectric sensors arranged to detect the passage or lack of passage, indicative of the cassette orientation, of at least one pair of aligned holes in the enlarged portion of the cassette when a cassette is moved from the loader and into the chute.
