Abstract

A continuous delivery apparatus for continuously feeding a lengthy work material wound into an approximately ring-like form to a press or the like. This apparatus comprises a rotatable turn-table on which wound material is placed so that an axis of the material is crossed perpendicular to the turn-table, a motor for rotating and driving the turn-table, and a swing arm, one end of which is supported on a rotating shaft whereas the other end thereof is pivotable from a center of the wound work material to an outer peripheral direction, said swing arm being always biased in an outer peripheral direction. The swing arm which is pivotally moved with a change in wound amount of work material is removed as an amount of rotation of the rotating shaft, said amount of rotation controlling the rotational speed of a motor to deliver work material at a constant speed at all times.

Claims

1. A continuous delivery apparatus for work material for continuously delivering a wound work material to a working machine, comprising a rotating support device comprising a rotatable turn-table on which the wound work material is placed so that an axis of said material is vertically disposed and perpendicular to said turn-table and a motor for rotating and driving said turn-table;

and a control device comprising a detecting member positioned above the turn-table, means supporting a portion of said detecting member for movement above and in a generally radial direction from the center of the wound work material toward the outer periphery thereof, said portion being engaged with the outer end of the wound work material so that said end is pulled across the wound work material in a radial direction thereof, a biasing device for continuously biasing said portions of said detecting member in said generally radial direction from the center of the wound work material toward the outer periphery thereof; and

a speed setting device for setting the rotating speed of the motor in response to movement of said supporting portion.

2. A continuous delivery apparatus according to claim 1, wherein said detecting member comprises a swing arm, one end of which carries said portion and which is pivotally moved up and down relative to said wound work material, and a rotating shaft which is mounted on the other end of said swing arm and rotated by pivotal movement of said swing arm, said speed setting device being actuated in response to the rotation of said rotating shaft.

3. A continuous delivery apparatus according to claim 1, wherein said detecting member comprises a swing member, one end of which defines said portion and which is horizontally pivotally moved on said wound work material, and a conversion member mounted on the other end of said swing member to convert the pivotal movement of said swing member into rotational movement, said speed setting device being actuated by the rotation of said conversion member.

4. A continuous delivery apparatus according to claim 2, wherein said speed setting device comprises a rotary type variable resistor having a rotatable shaft, sprockets mounted on said rotating shaft and the rotatable shaft of said variable resistor, and an endless chain belt stretched over said two sprockets.

5. A continuous delivery apparatus according to claim 3, wherein said conversion member comprises a chain belt, one end of which is mounted on said other end of said swing member and the other end of which is mounted vertically movably up and down relative to said work material, and a sprocket engaging said chain belt.
