Abstract
Apparatus suitable for guaranteeing a quick and automatic change of materials wound on reels, said apparatus consisting mainly of a reel-alternating mechanism combined with a mechanism for cutting and reconnecting the reeled material.
Claims12
Reel-changing apparatus for feeding working machines, wherein there is provided an assembly for cutting and reconnecting the reeled material (T), comprising:
- a cutting tool (CT) positioned for intercepting a first face of the material (T) of a band unwound from a first reel (BB1) standing in the working position and exhausted or close to exhaustion, said cutting tool being capable of positioning itself transversely on said first face of the material (T) unwound from said reel (BB1);
- a counter-acting tool (BM) capable of intercepting a second face of the material (T) of said band, at the cutting tool (CT), and provided with a suction head (ASP), said counter-acting tool being capable of moving from a rest position to a working position in contact with the material (T) of the band unwound from said reel (BB1) exhausted or close to exhaustion;
- wherein the mobile cutting tool (CT) and the counter-acting tool (BM) cooperate with each other for cutting the material (T) unwound from said first reel (BB1) and
- wherein the counter-acting tool (BM) holds by air suction the edge of the material cut from said first reel (BB1) for bringing said edge to being reconnected to the leading edge of a second reel (BB2) brought to the working position by the apparatus in replacement of the first reel (BB1).

Reel-changing apparatus for feeding working machines, comprising:
- a mobile support (SS) capable of guided traveling motion;
- a carousel (GS) rotatably supported by said mobile support (SS);
- two or more reel-holders (B1,B2) connected to the carousel and arranged symmetrically with respect the rotation axis of the carousel;
- a movement actuating device (C,1) capable of causing rotation of the carousel (GS) around said axis, said device alternating each of the reel-holders (B1,B2) in the same angular working position;
- a control device (P) that controls the guided traveling of said mobile support (SS) and is capable of causing retraction of the mobile support (SS) away from a working position and of causing the forward movement of the mobile support in the opposite direction once the carousel has performed one rotation around its rotation axis for bringing a second reel-holder (B2) to said working position.
