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 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, object of this intention comprises some known initial steps, included in the preamble of the first claim and that include:
  • this method comprises, once said first half has been laser marked:
  • 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:
  • 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.
  • 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.
  • the trousers are initially folded by the crotch area such that the two halves (1a, 1b) of the trousers rest superimposed, and that the first and the second half (11a, 11b), 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 (11b) 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 (11b) facing a laser equipment (21) in charge of marking predetermined areas (10b) on said second half (11b).
  • 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 (10d) 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 (31a, 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 .
  • the assembly formed by the two pieces (31, 32) and their drive means is connected to a motor (33) that allows it to be rotated towards one or the other side.
  • the trousers (1) are moved, for example, by means of a conveyor belt, and positioned on the piece (31) of the motorized automatic rotation module (3).
  • the piece (32) rotates by the action of the motor (32a) positioning itself on the piece (31), so that the trousers are held between the two pieces (31, 32) and, as shown in Figure 3c , the set of the two pieces (31, 32) rotate together by the action of the motor (33) and the first half (11a) of the trousers that occupied the top position happens to occupy the bottom position, with the second half (11b) of the same side of the trousers facing the top area.
  • the piece (31) rotates by the action of the motor (31a), returning to the initial position shown in Figure 3a .
  • Figures 4a - 4e show an exemplary embodiment of the automatic unfolding and folding module (4) for unfolding and folding the trousers in the opposite direction, used in the device to change the visible side, front or back, of the trousers (1).
  • this automatic unfolding and folding module (4) comprises: two conveyor belts (41, 42) for the entry and exit of the trousers, arranged horizontally; two pairs of conveyor belts (43, 44), top and bottom, arranged vertically for the unfolding of the trousers and their folding in the opposite direction with the support of an unfolding guide (45) movable in a lateral direction and a rotatable folder (46).
