Definitions

  • the invention is in the field of handling web materials applied to the field of printing, and more particularly applied to cutting machines printed patterns on such a material. It relates to a cutting machine a strip-shaped and roll-packaged printing medium, which is arranged to separate patterns printed on the support from a tape scroll against a moving cutting tool. .
  • a support which consists of a sheet or the like shaped web and packaged in roll.
  • the strip, on which the patterns are printed beforehand, is driven from a reel to a movable cutting tool, against which the tape scrolls to separate the previously printed patterns from the latter.
  • cutting machines mainly consisting of a loading station comprising the reel, an upstream conveyance station of the web to a cutting station comprising the cutting tool and its mobility means , and a downstream conveyor station of the band to an unloading station where the cut patterns are recovered and where the remainder of tape is evacuated.
  • the belt is driven by motor means comprising at least one rotary drive roller placed at the unloading station and around which the band is wound, possibly motorized roller trains being placed at the longitudinal edge of the strip and / or transversely to its direction of travel for its guidance and positioning between the various stations.
  • the cutting machine is structurally the simplest possible and as small a footprint as possible to reduce its cost of obtaining and to facilitate its installation on site, or even its use.
  • the means used to achieve a reliable and precise cutting patterns are likely to be complex, with the consequence of affecting the simplicity of structure, small size and ease of use of the machine. It comes out for designers looking for a compromise between these constraints.
  • the quality of the positioning and the drive of the belt between the loading and unloading stations must allow a reliable and precise cutting of the patterns. It is necessary that the conditioning roller of the belt is not only correctly positioned with respect to the general axis of progression of the belt, but also that the conditions of driving of the belt guarantee a maintenance in position of the latter according to this axis.
  • the modes of relating and relative mobility between the band and the cutting tool are also critical, and it is desirable that the cutting operation is performed as quickly as possible for patterns whose contour to be cut is likely to to be geometrically complex. Another difficulty lies in the treatment of the reasons after their separation from the band and their collection at the unloading station.
  • the machine is organized from a vertical extension chassis. It is common that such a chassis is organized in a trolley and that the modalities of operation of the machine are reduced to simplify its structure and limit its size.
  • Such a machine is particularly intended to treat a type of printing medium of cellular material, plastic material or similar printing medium, a thickness of the order of less than one millimeter.
  • Such a cutting machine currently uses the principle of cutting "half-flesh", which consists in partially slicing the band in depth to allow maintenance patterns on the band despite the cutting of their outline.
  • the printing medium is formed of at least two layers comprising the printed sheet and a pattern retaining substrate which are joined to each other by an adhesive film.
  • the strip cutting operation is to slice the sheet by preserving the retaining substrate and then removing the patterns from this retaining substrate.
  • the reel and the drive roll are respectively placed at the rear and the front of the frame, while the cutting station is placed at the top of the frame.
  • a martyr rule placed at the cutting station constitutes the counter-support member for the cutting tool.
  • Such a machine offers the advantages of being inexpensive and of reduced floor space, of being easily installed on site, allowing its quick and easy implementation from simplified adjustment operations, and of limiting the magnitude and frequency of maintenance operations. However, these advantages are provided to the detriment of the quality and precision of the cutting patterns obtained, or do not allow cutting patterns whose contour is geometrically complex.
  • the machine is organized from a horizontal extension frame arranged in a table.
  • a machine makes it possible to treat not only a printing medium of small thickness but nevertheless of rigidity offering a uniform natural hold, but also printing media that can be flexible and low natural hold in their plan, such as textiles, and / or supports thick print.
  • Such a cutting machine commonly exploits the principle of "full flesh” cutting, which consists in completely slicing the strip in depth until isolating the reasons for the remainder of tape.
  • the table provides a support and guide surface for the web through a martyred conveyor belt, which is closed in a loop on itself and which is provided with means of the vacuum type to adhere the web to the web. its surface.
  • Such adhesion makes it possible to maintain the strip in its general plane at the cutting station, and to retain the cut patterns until they are collected at the unloading station.
  • the tape runs on the table top and the cutting tool is able to move in a plane parallel to the plate to cut patterns whose contour is geometrically complex.
  • Such a machine promotes maintenance and effective training of the band in its general plan regardless of its weight and / or its thickness, and allows to freely organize the mobility conditions of the cutting tool to maximize the possibilities offered by cutting of the band.
  • the operating modes of the machine induce a large footprint of the ground table, and a complexity of the means implemented with consequent costs of obtaining and maintenance of the machine crippling for low print media thickness of the type of cellular material, plastic material or analogous printing medium.
  • the object of the present invention is to propose a machine for cutting printed patterns on a support formed a roll-wrapped band, which offers a satisfactory compromise between the various constraints that have been set forth. It is more particularly targeted by the present invention to provide such a cutting machine which is of a simple structure, a small footprint and easy operation to implement, but which nevertheless allows to make reliable accuracy and the speed of the cutting of the patterns, including for patterns whose contour is geometrically complex.
  • the machine of the present invention is arranged to cut printed patterns on a support formed of a packaged web roll.
  • This machine is of the type comprising a vertical extension frame provided with a base for resting on the ground. It will be understood that this frame is oriented so as to circulate the band in a substantially vertical orientation corresponding to that of extension of the machine, or by analogy more or less inclined. It will be noted that a result sought for such vertical expansion cutting machines lies in a reduction in their footprint on the ground, from a displacement of the band in a plane as close as possible to verticality.
  • the machine comprises for the conveyance of the band, means for driving the latter along a progression axis corresponding to the unrolling extension of the band.
  • These drive means use at least one motorized roller arranged transversely to the axis of progression of the strip to circulate to a cutting station interposed between a loading station arranged in a reel of the strip and an unloading station for evacuation of the strip after cutting.
  • the cutting station uses a cutting tool which is movable along two axes of maneuver, composed of a first axis of maneuver corresponding to the depth of the band for its slicing and a second axis of maneuvering aligned transversely to the axis of progression.
  • the cutting operation is carried out according to a contour assigned to at least one pattern to be cut, taking place from a combination of movement between the circulation of the strip along the axis of progression and the movement of the tool cutting along the second axis of mobility.
  • a machine of the above-mentioned kind is mainly recognizable in that the drive means implement a conveyor belt closed in a loop on itself, which is provided with means for adhering the strip to its outer surface. .
  • This conveyor belt is engaged on at least one drive roller, being closed loop on itself.
  • the loop conveyor belt extends interposed between the loading station and the unloading station, which are placed on either side of the large side faces of the frame.

  • the loop closure of the conveyor belt is carried out from the engagement of the conveyor belt on at least a first drive roller, and on a second roller which is indifferently a second drive roller or a return roller of the conveyor belt idly mounted on the frame.
  • the band is maintained and driven through its surface corresponding to the adhesion surface offered by the conveyor belt, to reinforce its maintenance in its general plane despite the monodirectional antagonistic mobility of the tool of section along its second axis of mobility.
  • the closing of the loop conveyor belt and its orientation in verticality or the like makes it possible to use one and the other of its large lateral faces to hold the strip, with the advantage of reinforcing this holding for a vertical extension of the carpet. conveyor as small as possible.
  • the limitation of the unidirectional mobility of the cutting tool which simplifies the methods of use of the machine and which simplifies its structure, does not induce inaccuracy in the cutting performed.
  • the band is held by plating against the outer surface of the conveyor belt, which is used for the cutting tool of a martyr member adapted to allow a cut in full flesh of the band and to prevent slipping and / or possible wrinkling of the latter despite the monodirectional displacement of the cutting tool transversely to the axis of progression of the strip.
  • the organization of the means for holding and driving the belt conveyor belt makes it easy to arrange such holding and driving means to be able to cut patterns in a contour of complex geometric shape, from an alternating movement imparted to the conveyor belt which makes it possible to move the strip alternately on either side of the second axis of maneuver of the cutting tool for the cutting of such an outline.
  • the conveyor belt is advantageously a drive member of the belt back and forth relative to its position at the base of the second axis of mobility of the tool. chopped off. More particularly, the conveyor belt is advantageously operable by the drive roller in the two opposite directions corresponding to the axis of progression of the belt, so that from a driving of the drive roller selectively following the one or the other of its directions of rotation, the conveyor belt is alternately displaced in the said opposite directions.
  • the drive roller is preferably placed at the cutting station to form a counter-support member for the cutting tool. It will be understood that the cutting tool preferably moves along its second axis of mobility in a direction parallel to a generatrix of the drive roller, while being slightly offset relative thereto along the axis of progression of the belt for avoid injuring the drive roller.
  • This driving roller is preferably used to form a return roller participating in the looping of the conveyor belt.
  • the adhesion means may be of any type, such as vacuum type or electrostatic type, for example.
  • the conveyor belt is for example formed from a porous and / or microperforated textile, such as based on mixed fibers or the like, conferring on it a permeability ability to the air.
