Definitions

  • This invention refers to a machine for drawing a textile web out of a roll containing the same and which enable various modular elements to be easily incorporated therein.
  • Currently known machines for drawing a textile web out of a roll consist essentially of a trolley carrying the textile, which can move the length of of a table on which the textile is to be drawn the said trolley having two side upright members provided with wheels and rods which join the members together as well as at least one textile web feed roller and its corresponding guide tubes, a cutting unit and a zig-zag folding unit.
  • the cutting unit consists essentially of a cutting head able to travel transversally while the folding unit is made up essentially of a pair of swivelling clamps fitted to one extremity of the trolley and associated with a pair of folder clamps at each end of the table, the said clamps being provided with a stop so as to limit their angular travel.
  • the improvements in machines for drawing a textile web out of a roll containing the same are characterised in that the manual advance cutting module may be converted to a motorized unit by attaching an integrated accessory which includes, mounted on a single profile bar a motor with its belt and pulley drive this being fixed at the drive head using the same support member which serves to carry the handle for the manually operated version.
  • hte cutting and zig-zag folder and other accessory modules are attached at each end to endless chains which run on sprockets mounted on the respective side members of the trolley to enable them to be raised vertically.
  • the swivelling zig-zag folder clamps are mounted on the cross bar which is a joining member of the module structure and the stop limiting its angular travel is positioned on a flange attached to the said cross bar.
  • the same flange acts as a limiting stop also for the linear travel.
  • Another characteristic of this invention is a pair of orifices, one in each of the upright side members so that a second feed roller can be fitted.
  • the web feed guide tubes being connected using an attachment to the lateral supports of the guide tubes of the first feed roller.
  • the cross-bars joining the side members are of a precise diameter and joined together by a central plate such that they can serve as guide rails for the lateral travel of a device for loading the roll, this central plate of the integrated unit being the base plate of the motor providing lateral movement of the said loading device.
  • the roll loading integral device comprises a frame which can travel the length of joining cross-bars mounted on wheels for this purpose and there being at both extremities of the frame motors for raising the arms supporting the roll of textile web, the frame being connected by chain or other drive mechanism to a motor for its lateral travel.
  • the loading device consists of a module containing the arm lifting motors it being easily fitted by simply locating the wheels on the cross-bars and securing the lateral travel motor on the central plate.
  • the bar holding the textile roll has at least on one of its extremities a braking device which comprises essentially a disc provided with a plurality of plastic studs in recesses which also contain springs internally and a metal plate having its surface in contact with the studs and provided with a spigot for limiting movement of the bar support arm.
  • a braking device which comprises essentially a disc provided with a plurality of plastic studs in recesses which also contain springs internally and a metal plate having its surface in contact with the studs and provided with a spigot for limiting movement of the bar support arm.
  • the spigot prevents the plate from turning, its surface rubbing on the plastic studs and exercising a braking action.
  • the improvements as disclosed herein permit the attachment of a variety of modules to the basic machine. Starting from a simple manual unit the various modules can be added so as to provide a completely automatic machine. Described above is the attachment of modules for automatic cutting, a second feed roller and an automatic loading device. The machine is provided with the corresponding control module for the operation of these devices.
  • Another characteristic of the invention is the provision in one of the lateral upright members of orifices for attachment and coupling up of a drive motor and both uprights have housings to take the shaft bearings so that the trolley of the machine may be converted from manual to automatic operation by mounting the motor and the transmission mechanism without the need to mechanically modify the unit.
  • This conversion responds to the concept of enabling the various modules contributing to the possible variations to be built up on a step by step basis.
  • the invention also allows for the provision of a motor gear train for at least one feed roller, this gear train unit comprising a first pinion taking its motion from the wheel, a second pinion engaging with the first pinion, a third pinion coaxial with the second pinion and engaging with a fourth pinion which in its turn engages with the first pinion, the second and third pinions being mounted on a common shaft through unidirectional bearings both operating in the same sense of giration.
  • the gear train also includes an idler shaft in the interior of the common shaft, provided with means of driving allowing to be coupled thereto a component having a unidirectional bearing device obliging the said idler shaft to rotate in the same sense as the common shaft.
  • the complete gear mechanism is mounted on a side plate forming a module which can be attached to the machine in an opening provided in one of the side members of the trolley.
  • This plate mounting is in the same modular concept as those already described.
  • Another improvement characteristic of the invention relating to the two feed roller disposition, the first roller being positioned nearer to the roll of textile and the second further away, is that both rollers are kinematically connected through a chain and pinion transmission the first roller being the driver and the second the driven, with the pinion of the second roller being mounted on a unidirectional bearing.
  • this roller is unable to rotate in the contrary direction, but invariably at a velocity equal to or greater than the first and hence avoiding the formation of creasing in the drawing out of the textile.
  • the invention includes advantageously a device to prevent turbulence consisting of a length of cloth or similar rolled on a cylinder which is placed horizontally and transversely at the exit position of the textile web arid having its extremity fixed to a batten which is connected to a pair of chains arranged vertically and driven by pinions fitted to the two upright side members of the trolley, the upper pinions being composite with the cylinder and having their primitive diameter equal to the diameter of the cylinder.
  • This protective device covers the open space between the two upright members above the textile which is being drawn out.
  • the device also includes a perforated plate in the space below the guide tubes. This avoids the effect of turbulence which could be caused by the passage of the textile between the uprights of the trolley and which could give rise to minor deformation in the continuous length of textile.
  • the means of attachment by hooking on the cutting, zig-zag and other modules of the trolley consists, in each of the two attachment plates of the cutting module, a pair of slots in the form of a horizontal slot followed by a vertical slot which can engage with a pair of screws in the respective upright members having their heads adapted to the width of the slots.
  • This device provides a rapid placing of the module without the necessity for any further attachment when the module is fitted.
  • the screws have been already placed in the uprights permanently.
  • a textile tensioning device adapted to the cutting module, this device comprising a plurality of metal strips situated between a support bar and a cross member which is in contact with the textile.
  • the tensioning device adapts itself well to the textile due to the flexibility of the metal strips.
  • the improvements also include two horizontal movement pantographs in the form of an articulated parallelogram one side of which can travel in two slots one being horizontal and the other defining a hyperbola the object of which is the retention of the textile at the end thereof.
  • the swivelling clamps on the zig-zag folding module are provided with a flange integral with the articulating bar and carrying a stop, the flange being capable of an angular movement and a linear movement the length of the said bar to provide a radial and lateral adjustment of the centralizing and the drop of the textile.
  • This invention includes a plurality of connection devices mounted on a guide rail and to which the various modules may be coupled-in electrically and progressively starting from the basic machine.
  • the cutting module includes a flexible pneumatic tube and a pair of snap-on sockets,one at each end of the tube and in the cross member of the cutting unit and in the body of the cutting disc operating motor so as to provide for the power supply to the motor.

  • the Zig-zag folder module -11- depends for its vertical movement on endless chains -27-, one at each extremity, and which gear with pinions -28- and -29- carried respectively on the upright side members -4- and -5-.
  • the swivelling clamps -12- and -13- of the Zig-zag folder -11- girate on their respective axes -30- and -31- which unite the module frames and the end stop for their angular travel is formed by the flanges -32- and -33- integral with the said axes.
  • the flanges -32- and -33- also act as limiting stops for the linear travel.
  • the machine in the invention is provided with a pair of orifices, one, -34-, in each of the upright members -4- and -5- for fitting a second feed roller -35-, the textile guide tubes associated with it -36- and -37- being carried on lateral prolongations -38- of the guide tubes -9- of the first feed roller -8-, thus offering a simple assembly operation.
