Definitions

  • This invention refers to a device and a procedure for the extraction of cuttings in the form of a continuous strip or ribbon for a cutting machine for flexible sheet material taken from a reel, with detection of the said cuttings.
  • the invention also refers to a cutting machine for flexible sheet material taken from a reel, which includes the said device for the extraction of cuttings in the form of a continuous ribbon.
  • Cutting-winding machines with the means for carrying out one or more longitudinal cuts in flexible sheet material, which is unwound from a single reel, together with the means to rewind the two or more resulting bands on corresponding smaller-width reels are known in the prior art. Also known are cutting machines for the production of consecutive transversal cuts in a flexible sheet material that is unwound from a reel in order to produce loose sheets. In general, both the longitudinal and the transversal cutting machines trim up the edges of the material taken from the reel, which thus generates a trimming or cutting in the form of a continuous ribbon that must be extracted from the machine, for example, and taken to a collecting container.
  • suction system for the cited extraction of the cutting in the form of ribbon, in which the suction system is connected to a pipe through which the cutting is removed.
  • suction system consists of a suction pipe for each cutting, of which there are normally two, corresponding to the two side edges of the material taken from the reel, with an open lower end, through which the corresponding cutting enters, together with an upper end that communicates with a collection pipe which, in turn, is connected to a fan that produces the suction flow inside the collector and, through the Venturi effect, also inside the suction pipes causes the circulation of the cuttings through their respective suction pipes and collector to the exterior where they are deposited inside the said collection container from which they are subsequently eliminated or recycled.
  • Each cutting circulates through its corresponding pipe in a loose fashion, meaning that the material in the form of ribbon is not guided in a precise manner, but instead with random movement within the space enclosed by the pipe walls.
  • the described cutting extraction devices have the disadvantage that when the cutting breaks and no longer enters the suction pipe or when the cutting jams inside the suction tube, the generated, but not extracted cutting can be wound onto any of the adjacent reels leading to a machine malfunction. This generally leads to production stoppages with the consequent economic and time losses.
  • One objective of this invention is to resolve the said disadvantages through the introduction of a reliable extraction device that reduces the possibility of the machine producing such failures.
  • the invention refers to a cutting extraction device for a machine that handles continuous flexible sheet material, of the type that includes a suction system connected to at least one pipe for suction dragging a cutting in the form of a continuous ribbon from the said machine.
  • This device is characterised in that it also consists of the means of detection, associated with the said pipe that are adapted to detect the random movement of the said cutting inside the pipe and means of processing, adapted to emit a control command for the said machine in the case of not detecting the said cutting movement inside the pipe.
  • the cited means of detection consist of at least one detector adapted for capturing an emission in at least two transversal directions through the said pipe and to emit at least one signal representing the said capture or an interruption of the said capture, while the said means of processing are adapted to carry out successive readings of the said signal, of which there is at least one, comparing each new reading with one or more previous readings and emitting the said control command in function of the results of the said comparison.
  • a device for the extraction of cuttings that detects both the breakage of the cutting as well as the jamming of the cutting inside the pipe, not only from the presence, but also the random movement of the cutting as it passes the means of detection.
  • the means of detection for the device in this invention do not distinguish between the presence of the cutting and the non-moving presence of the cutting, however, in either of the two cases, the device can consider it as abnormal extractor operation and shut the machine down before the cutting is able to wind itself onto one of the nearby reels and causes malfunction of said reel, thus avoiding timeouts in its production.
  • the means of detecting the cutting are optical and consist of at least two pairs of emitters and receivers aimed in different transverse directions through the pipe.
  • the emitter and receiver pairs may be of the reflection type, it is preferable for the emitter in each emitter and receiver pair to be facing its corresponding receiver and for the device to include at least four of the said pairs aimed in different transversal and diametrically-opposite directions and crossed through the pipe so that at all times there is at least one emitter and receiver pair detecting the presence of the cutting.
  • the means of processing are able to determine whether movement exists or not, and in a negative situation generate a control signal that, for example, produces the shutdown of the machine and avoids the previously described problems.
  • Each emitter and receiver pair detects the presence of the cutting when the said cutting is positioned in the beam generated by the emitter towards the receiver.
  • the said receiver sends a signal indicating that no cutting is present to the means of signal processing.
  • the emitter and receiver pair can consist of Light Emitting Diodes (LEDs), in which the LED emitter generates a beam of infrared light towards the receiver that detects the passing of the cutting.
  • the means of processing receive the signals from the various receivers and process them in order to detect the change of light produced by the cutting intercepting the beam of light.
  • the pipe consists of at least one transparent section, around which the emitter and receiver pair is arranged. Thanks to this transparency in the pipe, the means of detecting the cuttings can be easily fitted into a ring-shaped housing located outside the pipe, protected from impacts and dirt and easily accessible for maintenance operations.
  • this invention refers to a procedure for the extraction of cuttings, for a continuous flexible sheet material handling machine, of the type that consists of the steps to generate, by means of a suction system, a suction current inside at least one pipe and drag along through the said pipe, by suction, a cutting in the form of a continuous ribbon from the said machine.
  • the procedure is characterised in that it also includes the following steps of: detecting, by some means of detection associated with the said pipe, a random movement of the said cutting inside the pipe; and emit, by some means of processing connected to the said means of detection, a control command for the machine in the case of not detecting the movement of the cutting inside the pipe.
  • the invention refers to a continuous flexible sheet material handling machine, which consists of a device for the extraction of cuttings in accordance with the first aspect of the machine.
  • the procedure also consists of one machine shutdown stage (D), in the case of not detecting the cutting in stage (C).
  • a machine for the handling of rolls of flexible material which consists of the means of cutting the said material, together with a device for extracting the cuttings as the one described.
  • Figure 1 is a partial view of a machine designed, for example, for the production, handling and finishing of all types of small rolls of paper, plastic and composites that includes a device for the extraction of cuttings in accordance with the invention.
  • the said machine 1 receives sheet material 2, for example, paper or plastic, in the form of a band B that is taken from a reel, which is not shown, and which cuts longitudinally by means of suitable cutting elements 4, obtaining several bands of paper B1, B2, B3, B4, B5, B6 that are subsequently rewound, and performs a clean-up operation of the sides of the sheet material 2, from which residue or cuttings 5, 6 are obtained from the margins.
  • a cutting is understood to be any strip or fragment of material in the form of a narrow band or ribbon, in this case, of paper or plastic, which has been cut off and must be separated from the rest.
  • the cuttings 5, 6 are introduced into corresponding pipes 7, 7a where they are sucked by a Venturi effect generated, for example, by a fan or turbine 8, and taken towards an evacuation collector pipe 13 that ends through a spout 10 in a collection container 15.
  • a Venturi effect generated, for example, by a fan or turbine 8
  • an evacuation collector pipe 13 that ends through a spout 10 in a collection container 15.
  • the pipes 7, 7a may be considered as being any type of means by which the cuttings 5, 6, are transported with either an open or closed configuration.
  • the actual type of pipe employed will depend on each specific case of cutting material and the employed extraction device.
  • the suction of cuttings 5, 6 obtained by means of the fan 8 causes the said cuttings to circulate inside the pipes 7, 7a until they reach some means of detecting the cuttings 9, 9a, associated with the said pipes 7, 7a, which detect a random movement of the said cuttings 5, 6 inside the corresponding pipes 7, 7a.
  • the means or assembly for detecting the cuttings consists of a casing 11 associated with pipe 7 and several pairs of emitters and receivers E1-R1, E2-R2, E3-R3, E4-R4, E5-R5, mounted, in this embodiment, on a printed circuit board 14, arranged in various transversal directions through the pipes 7, 7a and arranged around a transparent tube 12 inside the casing 11.
  • each of the various pairs of emitters and receivers E1-R1, E2-R2, E3-R3, E4-R4, E5-R5, consists of LEDs (Light Emitting Diodes) which produce beams of infrared light and, because of their number and spatial layout, are able to detect the movement of the cutting 5 or 6 inside the corresponding pipe 7, 7a whatever its orientation.
  • LEDs Light Emitting Diodes
  • the movement of the said cutting 5 or 6 means that the infrared light beams generated by the emitters do not reach the receivers.
  • Some means of processing (not shown), also arranged inside the means of detecting the cutting 9, or at an associated remote point, receives the signals from the receivers and processes them in order to detect the changes in light produced by the intersecting or not of the cuttings 5, 6 in the infrared light beams.
  • the said cutting will no longer circulate inside the means of detecting the cuttings 11, and therefore, it will no longer break the infrared light beams generated by the emitters, which will then reach the corresponding receivers.
  • successive equal readings will also be produced from the detectors of each emitter-detector pair along the length of the pipe.
  • the said means of processing will send a signal to the central control computer for the machine 1 in order to issue a warning or to shut it down, preventing, for example, that broken or jammed cutting 5, 6 is wound onto any of the nearby reels or rollers or shafts causing a malfunction in the movement of paper 2 and the subsequent rewinding that results in production stoppages.
  • the said means of processing are adapted to perform successive readings of the said signals, comparing each new reading with one or more previous readings and issuing the said control command in function of the results of the said comparison.
  • pairs of emitters and receivers may be made up of other components and not LEDs, with optical systems being preferred.
  • the cited pipe 12 may be totally transparent or only have a certain transparent sector occupying a part of the pipe's circumference, or only have two windows facing each other, of sufficient size to allow the light beams from the emitters and receivers to pass.
  • the emitters and receivers can be arranged so that they project, at least partially, inside the pipe, which would make the transparent section unnecessary.
