Definitions

  • ABSTRACT A device for the unwinding and winding of webs of material in spools at one or more winding and unwinding stations carried by the end of one or more fore-arms articulated on a pivotable arm or circularplate, characterised in that it comprises in combination at least one drive means disposed or driven in the pivot axis of the arm or plate, this being a roller driven so as to possess a peripheral speed approaching the linear speed of the web in the machine supplied by the spool being unwound or wound, the latter being pressed at the desired moment upon the drive means which thus imparts its peripheral speed to it, for the purpose of braking in the case of unwinding or drive in the case of winding, and at least one-bearing, preferably retractable, disposed at the end of each fore-arm to take up the spool by its hollow centre, with or without shaft, for on. the one
  • the present invention relates to a device permitting of unwinding orwinding respectively webs of material in spools for the supply of machines which carry out operations such as printing, coating, transformation and the like.
  • Apparatuses which comprise several unwinding or winding stations intended for the change of spools during running.
  • security of operation is obtained at the cost of a complication of the components increasingtheir cost.
  • the present invention proposes furnishing a spoolcarrier device having two or more spindles, of novel construction permitting of correctly effecting the unwinding or winding of the webs of material in spools.
  • This device cooperates with an apparatus permitting the changing of spools while running, and comprising processes for pressing and cutting and especially that described below supplementary to the spool carrier.
  • the invention concerns a device for unwinding and winding webs of material in spools at one or more unwinding and winding stations carried by the end of one or more fore-arms articulated on a pivotable arm or circular plate, characterised in that it comprises in combination at least one drive means disposed in the pivot axis of the fore-arm or plate, this being a roller driven so as to possess a peripheral speed approaching the linear speed of the web in the machine supplied by the spool being unwound or wound, the latter being pressed at the desired moment upon the drive means which thus imparts its peripheral speed to it, this being for the purposes of braking in the case of unwinding or drive in the case of winding, and at least one preferably retractable bearing disposed at the end of each forearm to take up the spool by its hollow centrewith or without shaft, for on the one hand its lifting and unwinding and on the other hand its winding and discharge.
  • FIG. 2 is a lateral elevation representing the device according to the invention in the phase of unwinding of a spool
  • FIG. 3 is a cross-section of FIG. 2,
  • FIG. 4 is a lateral elevation of the winding device according to the invention.
  • FIG. 5 is a plan view of FIG. 4.
  • the spool carrier device 1 is constituted by support means comprising two circular discs or plates 2 and 3 guided in their rotation by rollers 4 and 5 fixed in two base frames 6 and 7 and applied to grooves 8 of these plates.
  • Each spool 9 rotates in two bearings 10 and 11 disposed on the ends of two fore-arms l2 and 13 which are articulated about an axle 14 between the two plates 2 and 3.
  • One or more assemblies of such arms can be installed in this way between the two plates 2 and 3.
  • Each spool 9 or core 15 is applied with a regulable pressure to a roller 16 or wheels l7-and 18 rotating coaxially of the plates 2 and 3, which causes the pivoting movement of the spool carrier fore-arms and the positioning of the spool 9 as a function of the decreasing diameter during unwinding and increasing diameter during winding of this spool.
  • roller 16 is replaced by a plurality of rollers 19 and 20 disposed on either side of the centre of the plates 2 and 3.
  • this plurality of rollers comprises the rollers or wheels 21, 22, 23 and 24 which can be mounted on connecting rods 25, 26, 27 and 28 fast with the centres of the plates 2 and 3.
  • the said rollers or wheels can be surrounded by one or more endless belts per pair.
  • the roller or wheels have a double role. Firstly these elements serve to set the fresh spool or fresh-core in motion, which are to be connected to the terminating spool, by imparting to the periphery thereof a speed approximately identical with that of the web. Secondly these elements serve to brake the spool in the course of unwinding or drive the spool in the course of winding, by their periphery.
  • articulated arms also have a double role: That of placing the spool in contact with the roller and that of easy gathering from the ground or discharge to the ground of the new spool in its own bearings by pivoting of the plates, these two roles being independent of the diameter of the spool.
  • connection of the fresh spool with the terminating spool during running can be achieved for example by the device as proposed by the invention by causing rocking of two levers carrying a cutter, by means of a straight edge fixed on the periphery of the spool, at a specific region in such manner that the glued web commencement precedes the straight edge and the cut takes place after the application of the web end by an elastic hub to the glued region.
  • the spool 9 is either lifted from the ground or deposited on the ground by the rotation of the plates 2 and 3 and pivoting of the fore-arms l2 and 13. During this time the spool 31 is in the course of unwinding or winding.
  • the spool-carrier bearings When there are two fore-arms l2 and 13 as visible in FIG. 3, the spool-carrier bearings will be arranged for rapid opening or retraction by conventional means (not shown).
  • a geared motor 48 can drive the rotation of the plate or plates 2 and 3.
  • FIG. 2 is likewise a lateral elevation showing the apparatus in the course of unwinding a spool with the position of the two spools and the different spool-carrier elements shortly before a change of spools, which can be effected by a connection system 29 indicated only by way of example.
  • FIG. 3 is a cross-section of FIG. 2 wherein the points A-B-C are developed into one end and the same plane. It explains firstly the position of the spool 9 in relation to the articulated arms 12 and 13 and the roller 16 or as represented in the drawing two wheels 17 and 18, the axle of which rotates in one or two bearings 40 and carries a drive element 41, for example a chain wheel.
  • FIG. 4 represents the apparatus in the course of the winding of a spool 9 driven by its periphery by means of the roller 16.
  • a fresh tubular core 42 is gripped on the winding shaft 43 and generally provided with glue 44 over a part of its periphery so as to fix the commencement of the web to be wound.
  • a device for unwinding and winding webs of material from or onto spools comprising support means, means mounting said support means for rotation about a first horizontal axis, drive means on said first axis, said drive means comprising at least one roller driven so as to have a peripheral speed approaching the linear speed of a web being wound or unwound, arms mounted for vertical swinging movement on and relative to said support means about further axes disposed on opposite sides of said first axis and spaced substantial distances from said first axis, and means on the ends of said arms to support spools to be wound.
  • said drive means comprising at least one roller coaxial with said axis.
  • said drive means comprising a plurality of wheels adjacent said firstmentioned axis.
  • said support means comprising a rotatable disc disposed in a vertical plane, and power means for rotating said disc.
  • said support means comprising at least one arm through whose midsection said first axis passes and through whose opposite ends said further axes pass.
  • a device as claimed in claim 1 and means to cut and adhesively secure together the ends of webs on said spools.
