Definitions

  • the present invention is applicable in the field dedicated to the decoration of garments and more specifically of trousers, by means of laser marking.
  • This technique consists of arranging the fabric surface to be decorated in the field of action of a laser module that projects a light beam thereon following a predetermined pattern in order to mark predetermined areas of the trousers.
  • this type of laser marking is carried out both on the front and the back of the trousers, using different techniques to handle and arrange the trousers in different positions within the laser marking areas.
  • a known method consists of arranging the trousers in a fully unfolded manner on a table or suitable support, such that the laser equipment conducts the marking of one of its sides, front or back, and then flipping the trousers to proceed with the marking of the opposite side, back or front.
  • Another known method consists of arranging the trousers in a folded manner, folded by the crotch area, so that the two legs of the trousers rest superimposed and the two halves of one of its sides, front or back, remain in a visible position, that is to say, oriented towards the outside; in this case, the laser marking of one of the two visible halves is carried out and then the trousers are manually flipped to conduct the marking of the other visible half of the same side, thus completing the marking of one of the sides of the trousers.
  • the trousers When marking of the other side of the trousers is desired, the trousers must be unfolded and folded back in the opposite direction, so that the two halves, left and right, of this second side remain in a visible position; performing the laser marking of one of said halves, then manually flipping the trousers and finally marking the other half of the same side.
  • This method considered to be the closest to the invention, allows for the left and right halves of each of the front and back sides of the trousers to lie flat, which allows a correct laser marking of any area of the trousers and involves an advantage over the method wherein the marking is conducted on the trousers arranged on a fully unfolded manner which inevitability causes the formation of wrinkles in the crotch area of the trousers and impedes a correct marking of said area.
  • the drawback posed by the marking of the trousers arranged in a folded manner, by the crotch area, is that manually flipping and manually unfolding and folding the trousers excessively increase the total amount of time used in handling and marking each trouser, limiting productivity and consequently increasing the operational costs.
  • Another method for laser marking trousers consists of arranging the trousers on a mannequin that simultaneously exposes the two halves of one of the sides of the trousers; however, this method requires more complex and expensive technology, and the interaction of the operator with the mannequin to place and remove the trousers, which also takes significant time.
  • This invention relates to a method for the laser marking of trousers and to a device for marking trousers according to said method; and has technical features aimed at marking the trousers arranged in a folded manner, by the crotch area, and significantly reducing handling time of the trousers, with the consequent increase in productivity and cost reduction.
  • the method for laser marking trousers comprises some known initial steps, included in the preamble of the first claim and that include: a) folding the trousers by the crotch area in a first direction, such that the two halves of the trousers, right and left, rest superimposed in a flat manner, and a first half and a second half of a first side of the trousers, front or back, remain in a visible position; b) arranging said first half in a marking area of a laser module, in a position facing a laser marking equipment; c) laser marking predetermined areas of said first half.
  • this method comprises, once said first half has been laser marked: d) automatically rotating the trousers in a motorized rotation module and arranging said second half in a marking area of a laser module, in a position facing a laser equipment, and; e) laser marking predetermined areas of said second half.
  • the automatic rotation of the trousers in a motorized rotation module avoids the intervention of an operator to carry out this operation manually and reduces the time needed to carry out this operation by approximately 25%.
  • this method includes, after marking the second half of the first side: f) unfolding and folding the trousers by the crotch area in a second direction, such that a third half and a fourth half of a second side of the trousers, back or front, remain in a visible position; g) arranging said third half in a marking area of a laser module, in a position facing a laser equipment; h) laser marking predetermined areas of said third half; i) automatically rotating the trousers in a motorized rotation module and arranging said fourth half in a marking area of a laser module, in a position facing a laser equipment; and j) laser marking predetermined areas of said fourth half.
  • unfolding the trousers and subsequently folding them by the crotch area in the opposite direction, in order to make the two halves of the second side of the trousers visible is carried out automatically in an automatic unfolding and folding module.
  • this method can be used regardless of whether the trouser positioning areas in the laser module are arranged in a vertical plane or in a horizontal plane.
  • a module for receiving the trousers folded by the crotch area - a laser module provided with an area for marking the trousers flat-folded by the crotch area;
  • the device advantageously comprises a module for automatically unfolding the trousers in one direction of rotation and for automatically folding the trousers in the opposite direction.
  • the device can comprise motorized transport means for moving the trousers through the different modules.
  • the marking area of the trousers in at least one laser module can be arranged in a vertical plane or in a horizontal plane.
  • FIG. 1 shows a succession of images of a trouser in different positions during the laser marking of the two halves of a first side, specifically its front side, according to the method of the invention.
  • FIG. 2 shows a sequence of images in which the trousers of the previous figure can be observed in different positions, specifically during its unfolding and folding in the opposite direction, and the laser marking of the two halves of a second side, specifically of its back side.
  • FIGS. 3a-3d show respective views of an embodiment of the module for rotating the trousers folded by the crotch area.
  • FIG. 4a shows a schematic perspective view of an exemplary embodiment of a module for automatically unfolding and folding the trousers in the opposite direction.
  • Figures 4b-4d show respective profile views of the automatic unfolding and folding module of Figure 4a, in different operative positions.
  • FIG. 4e shows a perspective view of the automatic unfolding and folding module, and of the trousers once said automatic unfolding and folding operations have been carried out.
  • the trousers are initially folded by the crotch area such that the two halves (1a, 1 b) of the trousers rest superimposed, and that the first and the second half (11a, 11 b), right and left, of one of its sides, in this case the front side, remain in a visible position, that is to say oriented towards the outside; then arranging the trousers in a marking area of a laser module (2), such that the first half (11a) of the front side faces a laser equipment (21 ) in charge of marking predetermined areas (10a) stored in a control program of the laser equipment.
  • the trousers are automatically rotated in a motorized automatic rotation module (3), such that the second front half (11 b) of the trousers (1 ) remains in a visible position.
  • the trousers are arranged in this position in a marking area of a laser module (2), with said second front half (11 b) facing a laser equipment (21 ) in charge of marking predetermined areas (10b) on said second half (11 b).
  • the laser module (2) can be the same one used to mark the first front half (11a) of the trousers, or another mode arranged in a trouser processing line.
  • the trousers are automatically unfolded and automatically folded by the crotch area in a second direction, as shown schematically in Figure 2, such that a third half (12a) and a fourth half (12b) of the back side of the trousers (1) remain in a visible position and oriented towards the outside.
  • the trousers are then placed in the marking area of a laser module (2), so that the third back half (12a) faces a laser equipment (21 ) in charge of marking predetermined areas (10c) on said third half of the trousers.
  • the automatic rotation of the trousers (1) is then carried out in a motorized automatic rotation module (3), analogous to that shown in Figure 1 , and which arranges the fourth half (12b) of the trousers in a visible position; the trousers being arranged in this position in a marking area of a laser module (2) provided with a laser equipment (21) in charge of marking predetermined areas (1 Od) on said fourth half (12b).
  • the device for the laser marking trousers comprises, at least: a module (not shown) for receiving the trousers flat-folded by the crotch area and which can be constituted by a table or a conveyor belt; a laser module (2) provided with an area for marking and arranging the trousers flat-folded by the crotch area; a laser equipment (21 ) facing the marking area of the trousers in the laser module (2); a motorized automatic rotation module (3) for rotating the flat-folded trousers and a programmable module (not shown) for controlling the operation of the device.
  • the motorized automatic rotation module (3) for rotating the trousers comprises two flat pieces (31 , 32), like a grid, mounted on respective axes of rotation that can be actuated independently by means of respective motors (31 a, 32a), such that said pieces (31 , 32) can be arranged coplanarly as shown in Figures 3a and 3d, or superimposed as shown in Figures 3b and 3c.
