Abstract
Abstract A device for accumulating and supplying lengths of material in sheet form or in cuttings, such as, for example, labels, adhesive stamps, revenue stamps, coupons and cuttings of various shapes, etcetera, to be used in wrapping machines in conjunction with a fixed container or vertical well-shaped cavity from the base of which the cuttings are removed so that they can be supplied to the wrapping units of a wrapping machine. This device consists of a cylindrical body which is rotatably supported around its vertical shaft above the well-shaped cavity and is provided with a plurality of peripheral compartments, each of which is able to contain a pile of cuttings. A plurality of movable supports is provided for supporting a given pile of cuttings at a point inside the compartments corresponding to where the base of the stack is located. The cylindrical body is caused to rotate in an intermittent fashion in such a way as to cause the compartments to halt, one at a time, in alignment with the aforementioned well-shaped cavity responsive to a photoelectric sensor sensitive to the level of the pile of cuttings in the inside of the wellshaped cavity. This allows the subsequent transfer of the cuttings from the compartments to the well-shaped cavity once a predetermined level has been reached inside the cavity.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
349 words
A device for accumulating and supplying material in sheet form or in cuttings which operates in conjunction with a fixed reception chamber so that the material is successively supplied to the fixed reception chamber and then supplied to a wrapping mechanism of a wrapping machine, comprising: a body, having an outer periphery, a portion of the outer periphery being disposed above the fixed reception chamber, said body being movable such that different portions of the outer periphery thereof come into alignment with the fixed reception chamber as the body moves; a plurality of body compartments provided along the outer periphery of said body, each of said compartments including means for receiving and containing a pile of material; moving means for causing said body to move intermittently so as to cause said body compartments to halt, one at a time, in alignment with the fixed reception chamber; a plurality of movable support means, each being contained in one of said plurality of body compartments, for supporting a pile of material within each respective body compartment, wherein said plurality of movable support means are movable radially with respect to said body and are provided with a member which cooperates with an operating device and works in conjunction with said moving means for intermittently operating said body, in order that said plurality of movable support means can be displaced radially from a support position within the compartments to one whereby the pile of material in the particular compartment located above the fixed reception chamber can be discharged therein, said plurality of movable support means engaging with a fixed rail so as to maintain stable their support position for the piles of material in all the other positions; and sensing means sensitive to the level of the pile of material inside the fixed reception chamber for activating said moving means and, after one of said body compartments has halted in alignment with the fixed reception chamber, causing the movable support means thereof to release the material contained in said body compartment so as to allow transfer of material into the fixed reception chamber.
Claim 2

A device for accumulating and supplying material in sheet form or in cuttings which operates in conjunction with a fixed reception chamber so that the material is successively supplied to the fixed reception chamber and then supplied to a wrapping mechanism of a wrapping machine, comprising: a body, having an outer periphery, a portion of the outer periphery being disposed above the fixed reception chamber, said body being movable such that different portions of the outer periphery thereof come into alignment with the fixed reception chamber as the body moves; a plurality of body compartments provided along the outer periphery of said body, each of said compartments including means for receiving and containing a pile of material; moving means for causing said body to move intermittently so as to cause said body compartments to halt, one at a time, in alignment with the fixed reception chamber; a plurality of movable support means, each being contained in one of said plurality of body compartments, for supporting a pile of material within each respective body compartment, wherein said plurality of movable support means are movable radially with respect to said body and are provided with a member which cooperates with an operating device and works in conjunction with said moving means for intermittently operating said body, in order that said plurality of movable support means can be displaced radially from a support position within the compartments to one whereby the pile of material in the particular compartment located above the fixed reception chamber can be discharged therein, said plurality of movable support means engaging with a fixed rail so as to maintain stable their support position for the piles of material in all the other positions; and sensing means sensitive to the level of the pile of material inside the fixed reception chamber for activating said moving means and, after one of said body compartments has halted in alignment with the fixed reception chamber, causing the movable support means thereof to release the material contained in said body compartment so as to allow transfer of material into the fixed reception chamber.
Claim 3
Dependent Claim
36 words
A device according to claim 1, wherein said plurality of peripheral compartments extend parallel with the axis of the body and, virtually for their whole height or vertical extension, have their external delimitation wall partly open.
Claim 4
Dependent Claim
17 words
A device according to claim 1, wherein the said moving means comprises a system of articulated levers.
Claim 5
Dependent Claim
17 words
A device for accumulating and supplying material in accordance with claim 1 wherein said body is cylindrical.
Claim 6
Dependent Claim
26 words
A device for accumulating and supplying material in accordance with claim 1 wherein said moving means allows said body to rotate about the vertical axis thereof.
