Technical Field

The invention relates to a device for laser treatment of trousers, comprising: [a] a laser beam generating device; and [ b ] a workstation with two mannequins. The invention also relates to a method for laser treatment of trousers using the device according to the invention.

Background

Devices for laser treatment of fabrics, in particular trousers, are known. In some cases, the pants are arranged on a horizontal flat surface (e.g., a plate, etc.). In other cases, the pants are arranged on the manikin such that during laser treatment the pants are in an upright position. Examples of these manikin devices are disclosed in patent documents WO 03/029545a1 and ES 2649745 a 1.

Patent document WO 2018/011447 describes a device for laser treatment of trousers comprising generator means for generating a light beam, a head and rotation means for rotating the head according to a vertical axis, wherein the head comprises an inlet defining an inlet axis and adapted to receive the light beam, an outlet defining an outlet axis, and an internal mirror. WO 2018/011447 describes that for the purpose of handling trousers arranged on a plurality of trousers tracks, the head is rotated and thus moved to direct the laser beam at one or the other of the trousers.

In some cases, the manikin extends the trousers so that they become substantially flat, but in other cases the manikin has means that allow the trousers to be given a three-dimensional shape (e.g. by means of inflatable balloons) (see also WO 2017/191347). Both solutions have their advantages and disadvantages.

Overall, there is still a need to find an economical mechanical solution that enables high productivity with less labor and allows high quality treatment of all points of the trousers surface, with high precision.

Disclosure of Invention

The object of the present invention is a new device for laser treatment of trousers, comprising: [a] a laser beam generating device, wherein the device defines an emission axis, a first aperture angle around the emission axis, and a second aperture angle around the emission axis in a plane perpendicular to the first aperture angle, such that the device is adapted to emit a laser beam in any direction within a light cone defined by the emission axis and the first and second aperture angles (emission cone); and [ b ] a workstation having two mannequins, each mannequin including an upper support structure, the upper support structure having a fastening area for the upper part of a pair of trousers, and two leg portions adapted to be received in the legs of the trousers extend from the upper support structure, wherein each leg defines a longitudinal axis, wherein the two longitudinal axes of the two legs of each mannequin define a mannequin plane, wherein each mannequin defines a longitudinal axis of symmetry arranged in a mannequin plane, wherein each of the mannequins is oriented towards the device, such that the emission axis illuminates the manikin plane at an angle of less than 90 deg. (wherein the angle is defined as the angle formed between the geometrically orthogonal projection of the emission axis on the manikin plane and the emission axis), and each manikin has at least one leg within the light cone.

In general, in the present invention, it is understood that the laser beam generating apparatus also includes a laser beam generating unit from which the laser beam exits, and a head at which the laser beam from the generating unit enters through an input and exits through an output. The head has internal mirrors (usually two, called galvanometer mirrors) in which an incident laser beam from the input is reflected and exits through the output. The movement of the one or more mirrors defines a first aperture angle and a second aperture angle. Furthermore, the mirror (or mirrors) in its neutral position define an emission axis, which is the direction of the laser beam leaving the head when the mirror (or mirrors) is in its neutral position. The point of intersection of the emission axis with the mirror or the last of the mirrors (if there is more than one mirror), i.e. with the mirror closest to the head output, defines the origin of the emission axis. In the present invention, the head as a whole does not move with respect to the laser beam generation unit, that is, the head as a whole is fixed with respect to the laser beam generation unit. In other words, the head as a whole cannot rotate by itself, nor can it move relative to the generating unit. Therefore, it is different from the device disclosed in patent document ES 2649745 a 1. In this sense, it is understood that the head does not move or rotate to direct its output laser beam from one phantom to another, although it may move or rotate relative to the laser generating unit to properly align itself, focus the laser beam, or the like.

In fact, the device according to the invention is suitable for handling two trousers arranged on two manikins, without the need to move the manikins (as described in patent document WO 03/029545a 1) and without the need to rotate the device or the head (as described in patent document ES 2649745 a 1). The device according to the invention is suitable for treating the entire surface of the trousers on both manikins, by means of the movement of the mirrors housed inside the head or galvanometer mirrors only. In addition, the drawbacks due to the use of manikins, which allow trousers to have a three-dimensional shape (for example, by inflatable balloons), such as shadows (shadowing) or very oblique angles of incidence, are reduced given the orientation of the manikin with respect to the emission axis.

In a preferred embodiment of the device according to the invention, the two legs of the two manikins are within a light cone. In this case, a single laser beam generating apparatus is sufficient (therefore, only a single laser beam generating unit and a single head are required). It is only necessary to ensure that both trousers are within the cone of light defined by the emission axis and the first and second opening angles.

Alternatively, in another preferred embodiment of the apparatus according to the invention, the apparatus additionally comprises a second laser beam generating device, wherein the second emission axis, a third opening angle around the second emission axis and a fourth opening angle of the second device around the second emission axis in a plane perpendicular to the third opening angle are defined such that the second device is adapted to emit the laser beam in any direction within a second cone of light defined by the second emission axis and the third and fourth opening angles (second emission cone of light), wherein each of the mannequins is directed towards the second device such that the second emission axis illuminates the mannequin plane at an angle smaller than 90 ° (wherein the angle is defined as the angle formed between the second emission axis and a geometrically orthogonal projection of the second emission axis on the mannequin plane), and at least one leg of the mannequin is within the second cone of light, such that any leg of any mannequin is within at least one of the cone of light and the second cone of light. The solution is therefore an apparatus with two generating devices, which has further advantages. Thus, since the combination of two trousers does not have to fit each of the light cones, the distance between the generating device and the trousers can be reduced, reducing the difference in focal length between the two generating devices with respect to the manikin.

In the case of an apparatus having two laser beam generating devices, preferably only three of the manikin legs are within each of the light cone and the second light cone. In fact, as will be seen in greater detail later, this solution allows to implement a new method, whereby each generating device handles one of the trouser legs on one side of each trousers, while the other generating device also handles the other two trouser legs on one side thereof. Subsequently, the manikin is rotated 180 ° around its longitudinal symmetry axis, and each generating device again treats one of the trouser legs for each pair of trousers, for the side that has not been treated yet, and the other generating device treats the other two trouser legs, also for the side that has not been treated yet. Alternatively or additionally, it is advantageous that the two manikin planes are arranged in such a way that their perpendicular directions through the respective longitudinal symmetry axes intersect at a midpoint between the light cone vertex and the second light cone vertex. On the other hand, the emission axis and the second emission axis may be non-parallel to each other, but preferably both are parallel to each other.

Preferably, the emission axis illuminates the manikin plane of each of the manikins at an angle between 65 ° and 85 °, and in case of two generating devices, preferably the second emission axis illuminates the manikin plane of each of the manikins at an angle between 65 ° and 85 °.

Advantageously, the emission axis and the second emission axis are at the same height. Generally, it is preferred that the manikin is in a vertical position.

Advantageously, the emission axis and the second emission axis are separated from each other at their starting point by a distance comprised between 25mm and 1000mm, preferably between 50mm and 750 mm.

The invention also relates to a method for laser treatment of trousers using an apparatus according to the invention, in particular with two generating devices, characterized in that one of the two devices treats the legs of the trousers arranged on the manikin, which legs are on the right side from the viewpoint of the device, while the other device treats the legs of the trousers arranged on the manikin, which legs are on the left side from the viewpoint of the device. As will be seen later, in an example, this method enables the geometry of the device to be exploited in a particularly advantageous manner.

Another object of the invention is a method for laser treatment of trousers using the device according to the invention, in particular using two generating apparatuses, characterized in that each of the trouser legs of the trousers is treated on one side thereof by one of the apparatuses and on the other side thereof by the other apparatus. Preferably, the method comprises the step in which the apparatus treats the front portion of the first leg of each pair of trousers and the second apparatus treats the front portion of the second leg of each pair of trousers, then the trousers are rotated 180 ° around their longitudinal symmetry axis (that is, the manikin supporting the trousers is rotated), then the apparatus treats the rear portion of the second leg of each pair of trousers and the second apparatus treats the rear portion of the first leg of each pair of trousers. Alternatively, in another preferred solution, the method comprises a step in which the apparatus treats the rear portion of the first leg of each trousers and the second apparatus treats the rear portion of the second leg of each trousers, then the trousers are rotated 180 ° around their longitudinal symmetry axis (that is to say the manikin supporting the trousers is rotated), then the apparatus treats the front portion of the second leg of each trousers and the second apparatus treats the front portion of the first leg of each trousers.

One approach that is particularly advantageous is to combine the two approaches outlined above.

Detailed Description

In fig. 1, a laser beam generating device 1 is very schematically shown. The device 1 defines an emission axis 11, wherein a first aperture angle 12 surrounds the emission axis 11 and a second aperture angle 13 also surrounds the emission axis 11 and is in a plane perpendicular to the first aperture angle 12. Typically (and preferably, but not necessarily), the first aperture angle 12 is horizontal and the second aperture angle 13 is vertical. The two opening angles 12 and 13 define, together with the emission axis 11, an emission cone 14 of the device 1.

It will be appreciated that the device 1 is in fact a more complex device, comprising not only the laser beam generating unit, but all the corresponding optical, electrical and mechanical systems. In particular, it comprises a head with galvanometer mirrors with their movement, control, refrigeration system, etc., as known to the person skilled in the art. It is important for the present invention that the head is fixed relative to the laser beam generating unit, since it is not suitable for directing its emitted light cone from one phantom to another. Since, as also described above, the head may be moved or rotated relative to the laser generating unit to properly align itself for focusing the laser beam or for similar purposes, it will be appreciated that the head need not be permanently fixed relative to the laser generating unit, but instead the head may be fixable, e.g. temporarily fixed, relative to the laser generating unit. Also, as can be understood from the above, when/at the head is fixed such that the light cone is fixed as a whole (i.e. such that the emission axis is fixed), it is evident that the laser beam moving (by the head) within the light cone can be moved from one mannequin to another mannequin, provided that each mannequin has at least one of its legs within the fixed light cone.

In fig. 2 and 3, a device 1 similar to the device in fig. 1 is shown with its emission axis 11 directed towards a flat surface such as, for example, a manikin plane 30. Fig. 4 shows the intersection between the emission cone 14 and the manikin plane 30 of the device 1 of fig. 2 and 3. In the case shown in these figures, the angle formed by the emission axis 11 and the manikin plane 30 is 90 °. Fig. 5 to 7 show the same, but with the emission axis 11 forming an angle of inclination with the manikin plane 30. It can be seen that in the case of an apparatus with a single device 1 and a single phantom, it is advantageous for the phantom plane 30 to be perpendicular to the emission axis 11 of the device 1, since greater uniformity and therefore greater processing accuracy and quality is achieved. However, as will be seen below, in the case of a device with two manikins, this is not the interesting fact.

Fig. 8 and 9 show a first embodiment of a device for laser treatment of trousers according to the invention. The apparatus comprises a laser beam generating device 1, the laser beam generating device 1 defining an emission axis 11, a first aperture angle 12 about the emission axis 11, the first aperture angle 12 being the angle between line a11 and line a12, and a second aperture angle 13 about the emission axis 11, the second aperture angle 13 being in a plane perpendicular to the first aperture angle 12, i.e. perpendicular to the paper (or screen) of the reader in fig. 8.

The apparatus further comprises a workstation with two manikins 31. The manikin 31 may be conventional. Each manikin 31 preferably comprises an upper support structure having a fixing area for fixing the upper part of a pair of trousers and from which two legs 32 adapted to be accommodated in the legs of the pair of trousers extend, wherein each leg 32 defines a longitudinal axis 33, wherein the two longitudinal axes 33 of the two legs 32 of each manikin define a manikin plane 30, wherein each manikin 31 defines a longitudinal symmetry axis 34 arranged on the manikin plane 30.

Each of the manikins 31 is directed towards the device 1 such that the emission axis 11 illuminates the manikin plane 30 at an angle α 1 smaller than 90 °. In fig. 8, the angle β 1 has been shown, the angle β 1 being equal to 90 ° - α 1. In this embodiment, two manikins 31 have two legs 32 within the light cone 14 of the device 1.

For example, the following values may be given:

A11＝A12＝2100mm

B11＝B12＝2075mm

C11＝C12＝2130mm

H1＝1970mm

T1＝1705mm

β1＝14.82°(＝90°-α1)

fig. 10 shows a pair of two laser beam generating devices 1 and 2 schematically represented. The first generating device defines the elements already described in fig. 1. As such, the second generating device 2 defines a second emission axis 21, wherein the third aperture 22 surrounds the second emission axis 21 and the fourth aperture 23 also surrounds the second emission axis 21 and is in a plane perpendicular to the third aperture 22. Typically (and preferably, but not necessarily), the third aperture angle 22 is horizontal and the fourth aperture angle 23 is vertical. The two opening angles 22 and 23 define, together with the second emission axis 21, a second emission cone of the second device 2. Furthermore, the two devices 1 and 2 are separated from each other by a distance d. The distance d is generally defined as the distance between the origins of the two emission axes 11 and 21, although in this embodiment the two emission axes 11 and 21 are parallel to each other, and thus the distance d is constant. Each of the manikins 31 is directed towards the devices 1 and 2 such that the respective emission axes 11 and 21 illuminate each of the manikin planes 30 at an angle α 2 smaller than 90 °. In fig. 11, an angle β 2 has been shown, which angle β 2 is equal to 90 ° - α 2. In general, it is preferred that the two phantoms are oriented such that the angle β 2 of each of them is the same, as shown in FIG. 11.

In addition, the emission axis 11 and the second emission axis 21 are at the same height. Generally, it is preferred that the emission axes 11 and 21 are horizontal, and therefore, the height is measured vertically from the ground.

Fig. 11 shows a second embodiment of the device for laser treatment of trousers according to the invention. In this case, the apparatus comprises a pair of generating devices 1 and 2, such as those in fig. 10. The first aperture angle 12 is between line a22 and line D22, and the third aperture angle 22 is between line a21 and line D21. Similar to what happens in fig. 8, the second aperture angle 13 and the fourth aperture angle 23 are perpendicular to the sheet (or screen) of the reader. The second embodiment also comprises a particularly advantageous alternative: only three of the legs 32 of the two manikins 31 are within each of the light cones. This allows the method according to the invention to be performed with the device, which makes it possible to optimize the distance between the generating devices 1 and 2 and the manikin, the laser beam incidence angle on the manikin, the minimization of shadow areas, etc. In addition, as can be seen from the numerical values of the following example embodiments, the overall size of the entire apparatus can be minimized:

A21＝A22＝1780mm

B21＝B22＝1736mm

C21＝C22＝1820mm

D21＝D22＝1802mm

H2＝1650mm

T2＝1705mm

d＝280mm

β2＝14.82°(＝90°-α2)

it can be seen that for a value of T2 (given by the width of the manikin 31) equal to T1, it is achieved that H2 is significantly smaller than H1, thereby reducing all other distances.

Fig. 12 shows another preferred embodiment of the present invention. In this case, the two manikin planes 30 are arranged such that their perpendicular directions through their respective longitudinal symmetry axes 34 intersect at a midpoint between the apex of the light cone 14 and the second light cone.
