The present invention relates to a mannequin as a support structure for a pair of trousers whereon laser marking operations are carried out in order to give the article a worn appearance in localised areas.
The invention also relates to an assembly made up of said mannequin and a movement cart, as well as a machine for loading and exposing trousers to the actions of a marking laser. The machine comprises at least two assemblies of a mannequin and a cart and distinguishing therein a loading area for the article on a mannequin arranged in said area and a marking area wherein the surface of the pair of trousers loaded on another mannequin is exposed oriented towards an apparatus emitting a laser beam in order to be marked.
Finally, the invention also envisages a system made up of the cited machine for loading and exposing trousers to the actions of a marking laser.
Jean trousers, also called jeans, with a worn appearance are already commonly included in the clothing in most closets. This worn appearance is given by the contrast of certain decoloured marks arranged in specific areas of the surface of the pair of trousers. The marking of said areas is performed by a laser treatment, wherein an apparatus emitting at least one laser beam reproduces a worn pattern on the surfaces of the pair of trousers (front, rear, rise area of the pair of trousers, etc.). The laser beam directed towards the surface to be treated is transformed into a local heating point which causes the evaporation of the inks of the fabric of the area focused on and successively the spot of the laser starts to trace the design of the worn pattern.
During the laser marking operation, it is essential for the surface of the pair of trousers to stay stretched or tensed, without wrinkles, in order to ensure a result in accordance with what is desired.
At first, machines were used for marking which consisted of a work table with a flat horizontal support surface whereon the flattened pair of trousers was arranged manually, and whereon an arm was arranged which projected the laser beam downwards on the areas of the pair of trousers oriented upwards. Specifically, in order to minimise the wrinkles in the area to be treated, one of the trouser legs was arranged on the work table, with the rise area of the pair of trousers resting on an edge of the table and the other trouser leg hanging from said edge. Then, for the other half of the pair of trousers, the pair of trousers was taken and the other trouser leg rested on the work table. In order to mark the areas exposed on the other face of the pair of trousers, it had to be flipped over on the flat support surface and proceed in the same manner with the two trouser legs. In order to mark other areas, such as that of the rise of the pair of trousers, the pair of trousers could be arranged resting and folded along it, with the two trouser legs on top of each other resting on the table. Nevertheless, in this type of machine the fabric of the area of the pair of trousers to be marked was not sufficiently tensed and the wrinkles caused deviations in the marking and therefore, flaws in the trousers, without mentioning that the results of the marking in the rise area were difficult due to the wrinkles present in said area and the impossibility of tensing said area, specifically where the two trouser legs are joined.

In order to solve these drawbacks, mannequins with open legs were developed whereon the trousers are mounted and said mannequins are exposed to the effects of the laser beam, moving them from one side to the other and being able to turn them around for the marking of the front and rear surfaces. These mannequins make up the current machines for laser marking, wherein a loading area of the pair of trousers on the mannequin is distinguished, and a laser-marking area, normally opposite from the loading area, wherein the pair of trousers placed on the mannequin is exposed in the different areas thereof to the effects of the laser beam emitted by a laser-emitting apparatus oriented towards the exposure area.
There are machines for laser marking of trousers wherein the loading station and the marking station are each provided with a mannequin and said mannequins are arranged on a common rotating arm each one occupying an opposite end, such that when it rotates, the mannequin whereon the pair of trousers to be marked has been loaded rotates and goes from the loading station to the marking one, and the mannequin wearing the pair of trousers whereon the marking has been performed in the marking station goes to the loading station, wherein the pair of trousers will be taken off the mannequin by an operator who will soon have a new pair of trousers to mark. Patent document WO03/029545 shows in
This type of machine has the drawback that once a pair of trousers on the mannequin of the marking station has been marked with laser, this already-loaded mannequin cannot go to the loading station to unload it and load another one until loading the pair of trousers on the other mannequin has ended, which is when the rotating arm will rotate and the two mannequins will trade positions. This represents downtime in loading and marking cycles wherein the marking time is rather short (for example, when the marking patterns of the model of trouser are less complex than others).
The mannequins for supporting a pair of trousers, commonly known in the sector as trouser holders, reproduce the geometry of the legs from the ankles to the waist in a position with open legs. Each mannequin comprises two leg structures securely joined to each other suitable to be housed inside the trouser legs of the trousers to be marked, wherein each leg structure is defined by a respective imaginary longitudinal axis wherein the respective trouser leg extends, an upper portion (the one closest to the waist of the pair of trousers which is below), a lower portion, in correspondence with the ankle area of the pair of trousers, through which the pair of trousers is introduced on the mannequin, a front portion whereon the front portion of the trouser leg is arranged, a rear portion whereon the rear portion of the trouser leg is arranged, an inner lateral segment whereon the inner edge is arranged which starts from the joining of the trouser legs to the lower end of the respective trouser leg, and an outer lateral segment, opposite from the inner one, whereon the outer edge is arranged which starts from the waist to the lower end of the trouser leg. Each mannequin is attached to a tensing mechanism by which the surface of the pair of trousers covering it goes from a loosened state to a maximum tensed state wherein the surface of the pair of trousers is extended and without wrinkles, prepared to receive the laser marking.
Some of these mannequins comprise inflatable portions for tensing the portions of the pair of trousers to be marked, like the ones described in the publication of patent application WO03/029545, referring to a method of the laser tracing spots on the surface of articles of clothing and a system to carry it out, and in the publication of patent ES2640831-B2.
Patent document WO03/029545 describes a machine provided with two inflatable mannequins with the arrangement of a common rotating arm mentioned previously. Each mannequin comprises a frame or guide provided with gripping means and adjustment means suitable for placing the article in the position it takes when used. The gripping means comprise a pair of L-shaped hangers opposite from each other which move away from each other in order to grip the pair of trousers by the waist. With respect to the adjustment means, these comprise a pair of air chambers connected to compressed air feed means suitable for inflating them, and a pair of rods, each one arranged on one side of the mannequin, which rotate with respect to a corresponding hanger to which they are articulated by the effects of operating actuators.
The air chambers are connected through respective sleeves to the compressed air feeding means connected to a plant’s compressed air distribution network. Each air chamber is placed outside of a supporting tubular element respectively and inside of a modular tubular structure which is characterised by a number of mutually coaxial tubular sleeves and arranged one after the other. These can be moved according to the two longitudinal axes wherein each tubular element extends in order to determine the areas wherein the air chambers are free so that, when properly inflated, they can expand freely, creating inflated areas which make it so the fabric placed over it is tensed and extends without wrinkles. By inflating said chambers, the lateral rods are inclined with the lower ends thereof on the outside having just tensed the pair of trousers. Despite the fact that the rise area of the pair of trousers extends with the inflating of the chambers, it is difficult to frontally position the joining area between the trouser legs, since no matter how much the mannequin rotates, the inflating of the legs hides a portion of this area and the laser cannot act on some of the points.
In document ES2640831-B2, the mannequins comprise two leg structures symmetrical to each other which extend according to a respective longitudinal direction, wherein each leg structure has a front portion corresponding to the front portion of the trousers, a rear portion, and an inflatable balloon arranged in the rear portion thereof. Each inflatable balloon in turn comprises an upper edge, a lower edge, an inner lateral segment with an inner edge, close to the other leg structure, and an outer lateral segment with an outer edge, opposite from the inner lateral segment, wherein said inflatable balloon has a longitudinal axis which passes through the geometric centre thereof and is parallel to the longitudinal axis of the corresponding leg structure.
Apart from the inflatable balloon, each leg structure comprises a flat front face and a flat rear face and a hollow space between both of them wherein an outer rod and an inner rod are housed, wherein the lower ends of said outer and inner rods are joined to a mechanism for unfolding the rods. The unfolding mechanism comprises, for each leg structure, a movable guide along the leg structure, two unfolding arms, each one with a free end joined in an articulated manner to said movable guide and a free end, and a support arranged below said movable guide. The movable guide is suitable for moving between an unfolded position, wherein it is closer to the support, and a folded position, wherein it is further away from the support. Furthermore, the unfolding mechanism also comprises two connecting rods, each of which has an end joined in an articulated manner to an intermediate point of the corresponding unfolding arm and the other end joined to the support, wherein, both in the folded position and in the unfolded position, the free end of each unfolding arm is below the end joined to the movable guide, such that, when they are unfolded, both unfolding arms have an upside-down V shape. Thus, the surface of the pair of trousers whereon the marking is to be performed is tensed by the inflatable balloon and by the free ends of the connecting rods when the arms are unfolded.
With respect to the marking of the rise area of the pair of trousers, said document ES2640831-B2 envisages in the mannequin an adjustment system for the rise of the pair of trousers, comprising a height adjustment bar which extends from the top downwards between the space existing between the two leg structures and a cross guide, arranged on the lower end of the adjustment bar, which has two longitudinal through holes each of which houses on the inside thereof one of the inner rods of one of the leg structures.
In the mannequins used until now there is still the difficulty of suitably exposing the rise area of the pair of trousers oriented towards the laser beam for the marking thereof, since especially the joining area between the trouser legs stays partially hidden by the considerable volume adopted by the trouser legs when the balloons or air chambers provided therein are inflated.
Another drawback which comes with the marking on this type of mannequins is that the operator must bend over each time they load a pair of trousers on the mannequin in order to make it pass the space of the waist and subsequently the two trouser legs through the lower end of the two leg structures of the mannequin and manually slide the pair of trousers upwards, the operator getting up in order to fasten it to the gripping means which are provided in the upper portion of the mannequin. Once the pair of trousers is gripped from the top, the tensing is executed and the operator revises the front and rear surfaces of the trouser legs, stretching the pair of trousers by hand until there are no more wrinkles in the areas to be marked. Likewise, once the pair of trousers has been marked in the areas planned according to the design pattern, the pair of trousers is then loosened and the operator must pull the pair of trousers downwards by hand and bend over again in order to take it off the two leg structures. These operations entail, apart from considerable time due to the manual operations, unsuitable positions for the operator which with time can create joint and back pain.
It would be desirable to provide a mannequin and a machine for loading and exposing a mannequin to a laser beam which would overcome the mentioned drawbacks, ensuring a precise reproduction on the pair of trousers of the pattern of wear marks in any area of the pair of trousers, including the joining area of the two trouser legs starting from which the rise of a pair of trousers is defined as the distance between said area and the waist, and that the loading of the pair of trousers onto the mannequin implies less physical effort for the operators, being able to shorten the time necessary for loading. Likewise, it would be desirable to reduce the downtime between the time for loading a pair of trousers onto a mannequin, the marking time and the unloading time. Another objective would be being able to achieve a better flattening of the different existing models of trouser, the dimensions and designs of which vary, since in addition to the sizes, there are trousers with different shapes on the lateral edges or seams thereof, trousers with trouser legs which form a larger or smaller angle between them, trousers with a high or low rise, etc.
With the object of providing a solution to the proposed drawbacks, it is disclosed a mannequin for supporting a pair of trousers whereon a laser marking is performed, known in the sector as a trouser holder. The mannequin comprises two leg structures suitable to be housed on the inside of the legs of the trousers to be marked.
Each leg structure is defined by a respective imaginary longitudinal axis wherein the respective trouser leg extends, an upper area, a lower area, a front plane whereon the front portion of the trouser leg is arranged, a rear plane, opposite from the front plane, whereon the rear portion of the trouser leg is arranged, an inner side whereon the inner lateral edge of the trouser leg is arranged, which goes from the joining of the trouser legs to the lower end of the respective trouser leg, and an outer side, opposite from the inner side, whereon the outer lateral edge of the trouser leg is arranged, which goes from the waist to the lower end of the trouser leg.
The separation distance between the inner side and the outer side of each leg structure is variable by means of a tensing mechanism by which each leg structure can adopt and go from a non-operative loosened position to a maximum tensed end position by increasing the separation distance between the inner side and the outer side. In the maximum tensed end position the front and rear portions of the trouser leg arranged on the leg structure are extended to the maximum, practically without wrinkles, in order to thus perform the laser marking on any of the portions to be marked.
Essentially, the mannequin object of the invention is characterised in that each of the two leg structures is coupled to a respective main rotation axis around which the leg structure is able to rotate by means of a respective articulation comprised by the mannequin for each leg structure, the main rotation axis of each leg structure being an axis parallel to the direction of the dimension of the rise of the pair of trousers or collinear with said direction. In accordance with said articulated coupling, the front planes of the two leg structures can form a plurality of angles between them, at least two angles larger and/or smaller than 180°, apart from obviously being able to also form 180°. It is worth mentioning that since the front planes are opposite from the rear planes, when the two front planes of the leg structures rotate around the main rotation axis in order to adopt a position wherein they form an angle between them, the respective rear planes will form the angle resulting from subtracting from 360° the angle formed by the front planes when they rotate around the respective main rotation axes thereof.
According to the preferred embodiment, the main rotation axis of each leg structure is an axis parallel to the direction of the dimension of the rise of the pair of trousers. According to another non-preferred alternative embodiment, the main rotation axis of each leg structure can be one same common axis which is parallel to or collinear with said direction of the dimension of the rise of the pair of trousers. In the preferred embodiment, much larger rotation positions can be adopted, from 0° to 360°.
By going from the non-operative loosened position to the maximum tensed end position, the distance between the inner side and the outer side of each leg structure has increased until it reaches a value which practically corresponds to the dimension of the width of the trouser leg in each segment, this width being understood as the one resulting from measuring one trouser leg from the lateral inner edge to the lateral outer edge with the pair of trousers flattened and stretched.
The rotation or turning of a leg structure can be performed independently from the rotation of the other leg structure, although preferred configurations are also possible wherein they rotate in a dependent manner, in unison.
It is reminded that the rise of the pair of trousers is understood as the distance from the joining of the trouser legs of a pair of trousers to the waist.
The capacity of the mannequin adopting different positions wherein the front planes of the leg structures thereof form, apart from 180°, larger and smaller angles, contributes to being able to load the trousers to be marked in a manner which is comfortable for an operator, introducing them folded along the line of the rise of the pair of trousers when the angle between the front planes is an acute angle. In addition to the foregoing, adopting positions with different angles enables better exposure to the laser of the fabric of the portions of the pair of trousers to be marked, since apart from the very maximum tensing of the maximum tensed end position, the surface to be marked can be oriented perpendicularly to the laser beam without hidden areas.
According to another characteristic of a preferred embodiment of the invention, each leg structure comprises in the upper area thereof a support wherein the inner side and the outer side are supported, and through which the leg structure is coupled to the respective main rotation axis around which the leg structure can rotate by means of a respective articulation.
According to another characteristic of this preferred embodiment, each support is attached to corresponding first transmission means through which a rotation is provided for each leg structure around the respective main rotation axis, such that each of the front planes of the two leg structures is able to rotate (dependently or independently) around the respective main rotation axis and adopt different positions wherein the two front planes form between each other a plurality of angles comprised between 0° and 360°.
According to another characteristic of the mannequin of the invention and starting from the embodiment wherein it is envisaged that each leg structure comprises the aforementioned support wherein the inner side and the outer side are supported, and through which the leg structure is coupled in an articulated manner to the main rotation axis, the inner side comprises a straight inner bar which extends in a direction parallel to that of the imaginary longitudinal axis, the outer side comprises a straight outer bar parallel to the inner bar, and for each leg structure an intermediate bar is arranged which is parallel to and between the respective inner bar and outer bar. The tensing mechanism comprises actuation means to provide the movement of the outer bar and the intermediate bar with respect to the inner bar, increasing the separation distance between them when going from the non-operative loosened position (A) to the maximum tensed end position (B), and decreasing the separation distance between them when going from the maximum tensed end position (B) to the non-operative loosened position (A). Furthermore, each support comprises on the inside thereof a guide for the movement of the corresponding outer bar of the outer side according to a trajectory perpendicular to the longitudinal direction wherein the outer bar extends.
According to another characteristic of the preferred embodiment of the invention, the intermediate bar is joined to the inner bar of the inner side and to the outer bar of the outer side of the same leg structure thereof by means of at least two connecting rods articulated on the two ends thereof (preferably two connecting rods parallel to each other between the inner bar and the intermediate bar, and two connecting rods parallel to each other between the outer bar and the intermediate bar). The outer side and the intermediate bar of each leg structure are arranged such that they are movable with respect to the inner bar of the inner side moving away from the inner side or moving towards the inner side when going from the non-operative loosened position to the maximum tensed end position, and vice versa.
According to another characteristic of the invention, applied to an embodiment wherein each leg structure comprises in the upper area thereof a support wherein the inner side and the outer side are supported, and through which the leg structure is coupled in an articulated manner to the main rotation axis, it is foreseen that the inner side comprises a plate with an inner profile which defines an outline simulating the shape had by the inner lateral edge of the trouser leg which goes from the joining of the trouser legs to the lower end of the respective trouser leg when the trouser leg is flattened with the front portion thereof and the rear portion thereof on top of each other, and/or that the outer side of each leg structure comprises a plate with an outer profile which defines an outline simulating the shape had by the outer lateral edge of the trouser leg which goes from the waist to the lower end of the respective trouser leg when the trouser leg is flattened with the front portion thereof and the rear portion thereof on top of each other. On the mannequin, the plates with inner and outer profiles, or most of them, are contained in a plane parallel to the front and rear planes of the respective leg structures thereof, the plate with an outer profile of each leg structure intended to come into contact with at least one portion of the outer lateral edge of the leg of the pair of trousers when the leg structure is in the maximum tensed end position (B).
According to another characteristic of the mannequin object of the invention, the plate with an inner profile and the plate with an outer profile have a thickness, measured in the direction perpendicular to the front plane of the leg structure, comprised between 0.5 and 6 mm, the thickness thereof being able to vary in different areas of the plates, the thickness being lesser in the segment of the plate closer to the ends able to come into contact with the edges of the trouser legs. The plate with an inner profile has a width which varies along the inner side, being wider in the area of the outline simulating the shape had by the inner lateral edge of the trouser leg at the joining point of the trouser legs, and narrower at the upper and lower ends.
Furthermore, in an advantageous manner, preferably on the plate with an inner profile, on the edge which defines the outline, a rise appendix is arranged, provided with a vertex at the free end thereof (the end opposite from the plate with an inner profile), the appendix being oriented according to an appendix plane which can be parallel, perpendicular or which forms a certain oblique angle with the plate with an inner profile of the respective leg structure. The rise appendix can be securely joined to the plate with an inner profile, for example by welding, or be configured like a fold of the plate with an inner profile, or according to another embodiment it can be arranged on the plate in a detachable manner, i.e., it is removable, joined by screws or by any other detachable joining means to assemble it and disassemble it from the plate according to the trouser design.
According to another characteristic of the mannequin object of the invention, in each leg structure, the inner side comprises a straight inner bar which extends in a direction parallel to that of the imaginary longitudinal axis and the outer side comprises a straight outer bar parallel to the inner bar, and the plate with an inner profile is detachably joined to the inner bar and the plate with an outer profile is detachably joined to the outer bar, the plates with inner and outer profiles being able to be disassembled from the respective inner and outer bars and be replaced by other plates with inner and outer profiles in accordance with another trouser design. According to another particular embodiment, the plates with inner or outer profiles can be detachably joined to the respective bars thereof by means of a single pivotable point so that they can pivot with respect to the bars and apply more pressure on the sides of the trouser leg on one side than on the other. The pivotable joint is likewise a detachable joint in order to be able to disassemble the plates with profiles and substitute them with others according to the design of the pair of trousers.
This configuration described previously wherein the outer and inner sides comprise respective outer and inner bars and respective plates with outer and inner profiles detachably joined to the bars can be applied to any mannequin configuration for supporting a pair of trousers whereon a laser marking is performed, which comprises two leg structures suitable to be housed inside the trouser legs of the trousers to be marked, wherein each leg structure is defined by a respective imaginary longitudinal axis wherein the respective trouser leg can extend, an upper area, a lower area, a front plane whereon the front portion of the trouser leg can be arranged, a rear plane, opposite from the front plane, whereon the rear portion of the trouser leg is arranged, an inner side whereon the inner lateral edge of the trouser leg can be arranged which goes from the joining of the trouser legs to the lower end of the respective trouser leg, and an outer side, opposite from the inner side whereon the outer lateral edge of the trouser leg can be arranged which goes from the waist to the lower end of the trouser leg, wherein the separation distance between the inner side and the outer side of each leg structure is variable by means of a respective tensing mechanism, wherein each leg structure can adopt and go from a non-operative loosened position (A) to a maximum tensed end position (B) by increasing the separation distance between the inner side and the outer side, the front and rear portions of the trouser leg arranged on the leg structure staying extended to the maximum in order to perform the laser marking on any of the portions. Thus, it is not necessary or essential for the described configuration of the outer and inner sides (comprising respective plates with outer and inner profiles) that each of the leg structures be coupled in an articulated manner to a respective main rotation axis around which it is able to rotate by means of a respective articulation, the main rotation axis of each leg structure being an axis parallel to the direction of the dimension of the rise of the pair of trousers or collinear with said direction, the front planes of the two leg structures being able to form between each other at least two angles larger and/or smaller than 180° when they rotate around the respective main rotation axes thereof. If the mannequin comprises the two articulated leg structures able to rotate around the respective main rotation axes thereof, it will be more advantageous because when the pair of trousers is loaded onto the mannequin, there will be no problems since it will not interfere with the plates with inner profiles if the mannequin is folded with the rotated leg structures practically on top of each other or forming an acute angle between the front planes thereof. If the mannequin does not have this capacity to rotate the leg structures thereof, then the inner sides will be configured to momentarily promote completely or partially hiding the plates of the inner profiles towards the inside of the inner bars without the plates of the inner profiles protruding excessively in order to enable separation between the plates of the inner profiles of both leg structures which enables the pair of trousers to pass.
According to another characteristic of the mannequin object of the invention according to a preferred embodiment, the support of each leg structure whereon the inner side and the outer side are supported comprises a first semisupport whereon the inner side and the outer side are supported, and a second semisupport by which the leg structure is joined in an articulated manner to a respective articulation by which the leg structure is able to rotate around the respective main rotation axis. The first semisupport and the second semisupport are joined in an articulated manner to each other, the first one with the ability to rotate with respect to the second one around an articulation for angular adjustment between the trouser legs with the ability to rotate around an angular adjustment axis, said angular adjustment axis being an axis perpendicular to the front plane or perpendicular to the plane wherein the inner side and the outer side of the leg structure are contained. The first semisupport and the second semisupport are configured articulated to each other by the articulation for angular adjustment such that when the first semisupport is rotated with respect to the second semisupport, the inner side of the leg structure varies the angle it forms with respect to the direction wherein the main rotation axis extends, which is parallel to the direction of the dimension of the rise of the pair of trousers or collinear with said direction, the mannequin being able to vary the angle the inner sides of the two leg structures form between each other in accordance with the trouser design.
According to another additional characteristic of this preferred embodiment of the mannequin of the invention, in each leg structure, the first semisupport supports the inner and outer bars of the inner and outer sides, respectively, the first semisupport and the second semisupport being configured as articulated to each other such that when the first one rotates with respect to the second one, the inner bar of the leg structure varies the angle it forms with respect to the direction wherein the main rotation axis extends, which is parallel to the direction of the dimension of the rise of the pair of trousers or collinear with said direction, the mannequin being able to vary the angle the inner bars of the two leg structures form between each other.
According to another characteristic of this preferred embodiment of the mannequin of the invention, the first semisupport and the second semisupport of each leg structure are made up of respective bodies, each provided with a front plate and a rear plate, parallel to the front plane and to the rear plane of the leg structure, said plates being provided with holes, pivots and slots in order to carry out the rotation of the first semisupport with respect to the second semisupport, each leg structure comprising an angle regulation mechanism to vary the angle formed by the inner sides of the two leg structures with each other or the angle formed by the inner bars of the inner sides of the two leg structures with each other, and locking means for that angle. In this manner, the mannequin is able to be adapted to the model of trouser to be marked and thereby adjusting it to the angle it has between the trouser legs.
Preferably, the angle regulation mechanism comprises a spindle arranged coupled in a fixed manner in the second semisupport with respect to which the spindle moves in a direction towards the first semisupport, provided with a head able to be rotated manually in order to advance the spindle, wherein the end of the spindle is introduced into the first semisupport. The angle regulation mechanism further comprises a nut crossed through by the spindle, said nut being provided with a pivot arranged in a direction parallel to the angular adjustment axis, and the pivot in turn being arranged inside at least one slot made in one of the front or rear plates of the first semisupport. All of this is arranged such that when the spindle is rotated, the nut moves with respect to the second semisupport and the pivot thereof exerts a pushing force inside the slot of the first semisupport, making the slot and the plate wherein it is located rotate with respect to the second semisupport around the angular adjustment axis.
Preferably, the locking means for the angle between the first semisupport and the second semisupport comprise an angle locking bolt which is parallel to the direction of the angular adjustment axis, provided at one end with a head and at the other with a tightening nut or wing nut, the angle locking bolt making up part of the second semisupport and a slot in the shape of a circular arch provided in a plate integrally joined to the first semisupport. The slot is crossed through by the angle locking bolt, the head staying on one side of the slot, and the tightening nut or wing nut on the other side of the slot and protruding out of one of the front or rear plates of the second semisupport. When the locking nut or wing nut is tightened, it is tightened against the plate, the head of the locking bolt is tightened against the slot and the rotation between the first semisupport and the second semisupport is immobilised.
According to another preferred characteristic, for any embodiment described previously, the mannequin object of the invention comprises, above the upper areas of the leg structures, a cylindrical or prismatic apical axial body which extends in a direction parallel to the direction of the main rotation axes of the leg structures, the apical axial body being arranged equidistant from the two leg structures and integrally joined to a body supporting the articulations by which each leg structure can rotate around the respective main rotation axis thereof, all of this configured such that when the leg structures rotate around the respective main rotation axes thereof, they move with respect to the apical axial body.
According to a second aspect of the invention, it discloses an assembly made up of a mannequin and a movement cart, characterised in that the mannequin is a mannequin like the one described in the previous paragraph (the one comprising the cylindrical or prismatic apical axial body), and in that the transportation cart is provided with movement motor means for the autonomous movement of the transportation cart along a guided trajectory. The transportation cart can be coupled to the mannequin for the joint transportation thereof along a guided trajectory, wherein said coupling to the mannequin is configured to enable access to the apical axial body from the outside of the movement cart and to enable the rotation of the mannequin independently from the transportation cart around a vertical rotation axis of the mannequin which coincides with the imaginary axial axis of the apical axial body of the mannequin when the apical axial body is arranged in a vertical position.
According to a particular embodiment of the assembly object of the invention made up of the mannequin and the transportation cart, the transportation cart is joined in an articulated manner to the mannequin through a loading rotation axis which is horizontal and perpendicular to the direction of the imaginary axial axis of the apical axial body of the mannequin, the mannequin being able to rotate around said loading rotation axis and able to adopt a special loading position (C) for trousers. In this special loading position (C), the front planes or the rear planes of the two leg structures of the mannequin are arranged forming an acute angle or arranged on top of each other, and said front planes or the rear planes being contained in non-vertical planes, and the imaginary axial axis of the apical axial body of the mannequin forms an acute angle with respect to the vertical direction, being able in said special loading position (C) to load onto the mannequin a pair of trousers folded on itself along the line defining the rise thereof. In fact, this same special loading position (C) is also useful for the unloading of the pair of trousers from the mannequin. Although it is possible to load a pair of trousers onto the mannequin by only placing the mannequin in a position with the front planes thereof at an acute angle, having rotated the leg structures around the respective main rotation axes thereof parallel to the rise axis, loading the trousers folded around the rise, without needing to adopt the mentioned special loading position (C), what is achieved with the special loading position (C) provides greater comfort, because the lower end of the mannequin is lifted with respect to the floor and the mannequin is rotated with respect to the vertical plane and thus the operator can introduce the pair of trousers onto the mannequin without needing to bend over as much.
This configuration by which the mannequins can adopt the special loading position (C) is very comfortable for the operator, since the trousers can be loaded onto a mannequin folded around the rise of the pair of trousers, with the trouser legs almost or practically on top of each other (which we do when folding a pair of trousers lengthwise, around the axis of symmetry of the pair of trousers), by being able to arrange the front planes of the two leg structures of a mannequin by forming an acute angle (or an obtuse angle, depending on whether the pair of trousers is folded with the front trouser legs on the inside or on the outside), according to the capacity thereof to rotate around the main rotation axis. Furthermore, by being able to rotate the mannequin around the horizontal axis perpendicular to the main rotation axis and by being maintained with the main rotation axis thereof forming an acute angle (preferably around 45° or less), the mannequin can be arranged with the front and rear planes of the leg structures thereof in inclined planes, not vertical ones (understanding as a vertical plane the one perpendicular to the support base of the marking machine) and the lower ends of the leg structures, from whence the mannequin is dressed with the pair of trousers, are thus higher and are further forwards than the rest of the mannequin, for which reason the operator loading the mannequin does not have to bend over in order to introduce the pair of trousers.
In summary, the operator does not have to load the pair of trousers in the habitual position thereof, with the waist extended (the front planes forming 180°) and bending over in order to pass underneath the pair of trousers, but rather the mannequin can be arranged with the front planes forming an acute angle (preferably around 20° or with the planes completely on top of each other), and in an even more comfortable manner, the mannequin or the mannequins in the loading area can adopt the special loading position (C), said front planes being inclined at an acute angle with respect to the vertical plane, being able to load the pair of trousers folded along and from a height comfortable for arranging the lower portion of the mannequin at the height of their hands when the operator is standing.
According to a third aspect of the invention, it is disclosed a machine for loading and exposing trousers to a laser for the marking thereof, comprising a loading area, wherein the loading of a pair of trousers onto at least one mannequin is performed, and a marking area wherein the pair of trousers loaded onto the mannequin coming from the loading area is exposed to the external effects of a laser for the marking thereof. In the machine object of the invention, the mannequin or mannequins make up a mannequin and transportation cart assembly in accordance with the assembly described above. Furthermore, in the machine of the invention the transportation cart is movable through movement motor means along at least one guided trajectory for the transportation of the mannequin from the loading area to the marking area, and from the marking area to the loading area.
According to a preferred embodiment of the machine of the invention, the machine comprises more than one loading area separated from each other, and respective guided trajectories for the transportation which converge at one same marking area, wherein the machine comprises at least one mannequin and cart assembly for each loading area.
According to another characteristic of the preferred embodiment of the machine object of the invention, the guided trajectories for the transportation are trajectories arranged radially with respect to the marking area located on one side or on both sides of the marking area, the marking area facing a laser device. For each loading area there can be one operator loading trousers in order to improve productivity.
According to another characteristic of the preferred embodiment of the machine object of the invention, the loading area comprises a motorised rotating positioning device with the ability to rotate around a vertical positioning axis, located after, but separated from, the guided trajectories for transportation by which the mannequins are led by the transportation carts from the loading areas to the end of the guided trajectories for transportation. The positioning device comprises a positioning rail with a straight trajectory able to be aligned, when rotated with respect to the vertical positioning axis, with any of the guided trajectories for transportation in order to receive in the marking area the mannequin led by the transportation cart, and it further comprises connection means able to connect to the apical axial body of the mannequin received in the positioning rail and cause the rotation of the mannequin around the imaginary axial axis of the apical axial body of the mannequin, when said imaginary axis is parallel to the vertical direction.
According to another additional characteristic of the machine object of the invention, the machine comprises a control device for detecting the presence of persons in any of the loading area or areas, configured to send a warning signal to the movement motor means of the transportation carts by which the advance speed of the transportation carts is controlled and varied in the guided trajectories for transportation, even being able to detect the advance thereof in any of the directions from the loading area or areas to the marking area and vice versa.
Although it will not result in being so advantageous, it is worth mentioning that the arrangement of the elements of the only marking area and of the loading areas forming the described machine can operate with any mannequin which does not need to have the ability to rotate the leg structures thereof around the respective main rotation axes thereof, since the marking is mainly done with the front planes of the leg structures arranged at 180°. It is enough for the mannequin to have, above the upper areas of the leg structures, a vertical cylindrical or prismatic apical axial body on the upper end thereof and centred between the two leg structures.
According to a fourth aspect of the invention, it is disclosed a system for the laser marking of trousers comprising at least one machine like the one described in previous paragraphs, according to the invention and, furthermore, at least one auxiliary device for the automatic loading and/or unloading of trousers to be loaded and/or unloaded onto a mannequin located in the loading area or areas of the machine.
The auxiliary system for the loading and/or unloading comprises a support base fixed on a surface such as a floor, a plurality of waiting supports, each of which in turn comprises a pair of oblong waiting profiles, wherein the waiting profiles of one same pair are parallel to each other, separated by a certain distance and they have a length such that they receive the insertion of the two legs of a pair of trousers in a folded position around the rise line of the pair of trousers. The waiting supports are arranged inclined and cantilevered, with the upper ends free and with the lower ends thereof coupled to movement means by which the waiting supports are movable with respect to the support base and in a guided manner according to a trajectory. The auxiliary device for loading and/or unloading also comprises an introducing arm made up of an inclined guide rail, fixed with respect to the support base and arranged above and facing one of the waiting supports of the plurality of supports. The length of the guide rail is such that it protrudes above the cited waiting support, the upper end thereof being located at the same level or a higher level wherein the upper areas of the leg structures of a mannequin located in the loading area of the machine are located. The introducing arm is provided with pushing projection means slidable along the guide rail and which protrude with respect to the guide rail towards the waiting support which it is facing at a distance such that the pushing projection means are able to push a pair of trousers arranged folded over the waiting support and move it along the guide rail to the upper end thereof for the loading of the pair of trousers onto the mannequin. In exchange, if the auxiliary device is used for the unloading of marked trousers, the pushing projection means push the marked and folded pair of trousers located on the mannequin and slide it downwards removing it from the mannequin and inserting it along the waiting support (free from the pair of trousers).
Preferably, the auxiliary device for loading and/or unloading is an automatic device, wherein each waiting support is able to be arranged in a point of the trajectory which follows in the movement thereof underneath the introducing arm, point wherein the inclination of said waiting support is parallel to the inclination of the introducing arm, and wherein the pushing projection means of the introducing arm protrude from the guide rail in the separation space between the two waiting profiles of the waiting support located underneath.
The pushing projection means slidable along the guide rail protrude with respect to the guide rail towards the waiting support, which it is facing, a distance such that the pushing projection means are able to push the pair of trousers arranged folded over the waiting support and move it along the guide rail to the upper end thereof. The pushing projection means can slide from the bottom upwards until they reach the joining area of the legs of the pair of trousers folded over the waiting support facing it. As they slide towards the upper end of the introducing arm, the pushing projection means drag the pair of trousers upwards, since it is pushed upwards by the joining area of the trouser legs, and they will carry it all the way up.
In order to make use of the auxiliary device for loading and/or unloading as an automatic loader, the first thing is to arrange a waiting support wherein a folded pair of trousers is supported and that this waiting support is facing the introducing arm. A mannequin free of a pair of trousers must also be placed, in the special loading position (C), meaning, with the front planes of the leg structures forming an acute angle (preferably around 20°) in order to receive a folded pair of trousers and also activate the suitable means for arranging the mannequin in the special loading position (C), with said front planes in non-vertical planes, and specifically with the same inclination that the introducing arm has. The two lower areas of the leg structures of the mannequin will be arranged after the respective waiting profiles which make up the waiting support, aligned with them. The pushing projection means will start the ascension thereof and will push the folded pair of trousers carrying it upwards by the joining area of the trouser legs. As the pair of trousers is dragged upwards, it will start to leave the waiting support and will enter the leg structures of the mannequin until the mannequin is dressed.
Alternatively or additionally, the pushing projection means can be provided with gripping elements such as for example clamps or hooking means, which grip or hook the waist of the pair of trousers or a portion thereof (for example a belt loop) and in this manner by sliding along the introducing arm they carry the pair of trousers introducing it onto the mannequin and once it is loaded, with the waist of the pair of trousers placed around the upper portion of the outer sides, there they release the pair of trousers from the clamping, gripping or hooking.
As a complement to the description provided herein, and for the purpose of helping to make the characteristics of the invention more readily understandable, this specification is accompanied by a set of drawings which, by way of illustration and not limitation, represent a first preferred embodiment and a second embodiment of the mannequin, of a mannequin and movement cart assembly, embodiments of the machine for loading and exposing the trousers to a laser for the marking thereof, and embodiments of the system comprising said machine and an auxiliary device for loading and/or unloading, all of these objects of the invention, wherein:
The mannequin 1 comprises two leg structures 2 suitable to be housed on the inside of the legs of the trousers to be marked, which are commonly called semi-trouser holders. Each leg structure 2 is defined by a respective imaginary longitudinal axis 20 (see
Each inner side 25 comprises a straight inner bar 25a which extends in a direction parallel to that of the imaginary longitudinal axis 20, and moreover, each outer side 26 comprises a straight outer bar 26a parallel to the inner bar 25a. Furthermore, for each leg structure 2 there is an intermediate bar 34 arranged parallel to and between the respective inner bar 25a and outer bar 26a. The inner bars 25a and the outer bars 26a are formed by bars or profiles having a front face and a rear face. The front faces of the inner 25 and outer 26 sides of a leg structure 2 are the ones which are taken into account in order to determine the front plane 23 of said leg structure 2, and the rear faces, opposite from the front ones, are the ones which determine the rear plane 24. The distance between the front plane 23 and the rear plane 24 translates into the thickness of the profiles or bars making up the inner 25 and outer 26 sides.
The mannequin 1 comprises a tensing mechanism 3 due to which the separation distance between the inner side 25 and the outer side 26 of each leg structure 2 is variable, such that each leg structure 2 can adopt and go from a non-operative loosened position A, shown in
According to the represented embodiment of the mannequin 1 in
The plate with an inner profile 25b and the plate with an outer profile 26b have a thickness, measured in the direction perpendicular to the front plane 23 of the leg structure 2, comprised between 0.5 and 6 mm (around 1.5 mm in many of the plates). Nevertheless, in a plate with a profile, the thickness, instead of being constant, can vary in different areas of the plate, the thickness being lesser in the segment of the plate closer to the ends able to come into contact with the edges of the trouser legs. Preferably, they are made of metal, and more preferably, aluminium. It can be seen how the plate with an inner profile 25b has a width which varies along the inner side 25, being wider in the area of the outline simulating the shape had by the inner lateral edge of the trouser leg at the joining point of the trouser legs, and narrower at the upper and lower ends.
It can be clearly seen in
The plates with an inner profile 25b are detachably joined (for example, by a joint screwed at one or more points, by a joint pivotable at one point) to the respective inner bars 25a, and the same thing occurs with the plates with an outer profile 26b, which can be detachably joined to the outer bars 26a, thereby being able to disassemble the plates with inner 25b and outer 26b profiles from the respective inner 25a and outer 26a bars, and be replaced by other plates with inner 25b and outer 26b profiles in accordance with another trouser design with a different shape of the lateral edges of the trouser legs. Thus, the plates with inner and outer profiles 25b and 26b can be changed, for example, by screwing them and unscrewing them from the inner and outer bars 25a and 26a, according to the model and size of the trousers to be marked.
The mannequin 1 stands out in that the two leg structures 2 are coupled in an articulated manner to a respective main rotation axis 5 around which each leg structure 2 is able to rotate by means of a respective articulation 51 comprised by the mannequin 1 for each leg structure, the main rotation axis 5 being an axis parallel with the direction of the dimension of the rise of the pair of trousers. It is recalled that rise of the pair of trousers is understood as the distance from the joining of the trouser legs (a point located underneath what corresponds to the fly of the pair of trousers if it has one) of a pair of trousers to the waist. Each leg structure 2 is able to rotate independently from the other leg structure 2, meaning, the rotation of one leg structure 2 does not have to influence the magnitude of rotation of the other leg structure 2, although in the preferred embodiment shown, the two leg structures 2 rotate the same magnitude of rotation and in the same direction of rotation.
This ability to rotate each leg structure 2 with respect to the main rotation axis 5 thereof enables the mannequin 1 to adopt multiple positions wherein to suitably expose practically any area of the pair of trousers to the effects of the laser, without there being portions of the mannequin 1 which are hidden or impede the laser beam from reaching the desired area, although most times the laser marking is done when the angle is 180°. This ability to rotate is also particularly advantageous for adopting the position like the one shown in
In order to perform the rotation of each leg structure 2 around the respective main rotation axis 5 thereof, each leg structure 2 comprises in the upper area 21 thereof a support 27 attached to transmission means 29 through which the rotation is imparted to the leg structure 2. The transmission means can in turn be coupled to motor means through which the independent rotation of each leg structure 2 is imparted. Each support 27 comprises two opposite main faces parallel respectively to the front plane 23 and the rear plane 24 defined in each leg structure.
The motor means of each leg structure, if they are had due to not being manual, can be formed by a servomotor for adjusting with precision the desired angle between the two front planes 23 (and therefore the angle between the two rear planes 24) and for a better control of the torque applied. The transmission means can be formed by straps and/or gears and thereby be the ones responsible for transmitting the torque generated by the servomotors to the supports 27 so that they are arranged forming between each other the optimal angles for the best exposure to the laser of the portion of a leg of the pair of trousers to be marked, without the other trouser leg interfering or creating hidden areas which impede the projected marking.
Nevertheless, according to the preferred embodiment, the two leg structures 2 rotate at the same time and the same angle, and the rotation can be imparted manually, without needing motor means. The transmission means of
Returning to the tensing mechanism 3 by which the mannequin 1 goes from position A to position B, said tensing mechanism 3 comprises actuation means shown in the partial cross sections of
The tensing mechanism 3 further comprises, for each leg structure 2, an intermediate bar 34 arranged parallel between the respective inner 25 and outer 26 sides, and practically coplanar with them, and that increases the separation distance with respect to the inner 25 and outer 26 sides when going from the non-operative loosened position A to the maximum tensed end position B, and decreases the separation distance when going from the maximum tensed end position B to the non-operative loosened position A. In fact, preferably and as seen in
The first semisupport 81 and the second semisupport 82 of each leg structure 2 are formed by respective bodies each provided with a front plate and a rear plate, parallel to the front plane 23 and to the rear plane 24 of the leg structure 2, said plates being provided with holes, pivots and slots in order to carry out the rotation of the first semisupport 81 with respect to the second semisupport 82. Each leg structure 2 comprises an angle regulation mechanism to vary the angle formed by the inner sides 25 of the two leg structures 2 with each other or the angle formed by the inner bars 25a of the inner sides 25 of the two leg structures 2 with each other, and locking means 88 for the angle between the first semisupport 81 and the second semisupport 82.
The angle regulation mechanism comprises a spindle 84 arranged coupled in a fixed manner in the second semisupport 82 with respect to which it moves in a direction towards the first semisupport 81, provided with a head 83 able to be rotated manually in order to advance or withdraw the spindle 84, wherein the end of the spindle 84 is introduced into the first semisupport 81. The mechanism also comprises a nut 85 crossed through by the spindle 84, said nut 85 being provided with a pivot 86 arranged in a direction parallel to the angular adjustment axis. The pivot 86 is in turn arranged inside at least one slot 87 made in one of the front or rear plates of the first semisupport 81. All of this is arranged such that when the spindle 84 is rotated in an advance direction, the nut 85 moves with respect to the second semisupport 82 and the pivot 86 thereof exerts a pushing force inside the slot 87 of the first semisupport 81, making the slot 87 and the plate wherein it is located rotate with respect to the second semisupport 82 around the angular adjustment axis.
The locking means 88 for the angle (see
According to the embodiment of the assembly shown in
Thus,
Thus, in the machine 10 of
According to other embodiments not shown, in the machines 10 of
Although it is not shown in the figures, the machine 10 comprises a control device for detecting the presence of persons in any of the loading area or areas 11, configured to send a warning signal to the movement motor means 74 of the transportation carts 71 by which the advance speed of the transportation carts 71 is controlled and varied in the guided trajectories for transportation 110, even being able to detect the advance thereof in any of the directions from the loading area or areas 11 to the marking area 12 and vice versa.
Thus, if an operator is close to a loading area 11 or the corresponding guided trajectory for transportation 110 thereof, the mannequin 1 which is already loaded will be transported slowly by the transportation cart 71 to the marking area 12, or for the case in which the pair of trousers loaded onto a mannequin 1 has already been marked and is transported from the marking area 12 to one of the loading areas 11 and the presence of an operator is detected, the mannequin 1 will also be transported slowly. Otherwise, when in the vicinity of a loading area 11 or of the guided trajectory for transportation 110 thereof, the presence of a person is not detected, the mannequins 1 loaded with trousers will be transported quickly to the marking area 12, and the same thing will occur when the pair of trousers has already been marked and needs to be transported to one of the loading areas 11 in order to unload it.
In the machines 10, the pairs of trousers loaded onto the mannequins 1 stay perfectly flat and enable a marking as if it were made on a table, with the difference that on this occasion the pair of trousers is in a vertical plane. The guided trajectories for transportation 110 and the trajectory within the loading area defined by the positioning rail 122 with a straight trajectory are only aligned when the loaded mannequin must go to the marking area 12 or must leave the marking area 12 in order to unload the pair of trousers; the rest of the time, during the marking, they stay unaligned. Furthermore, as seen in the figures, the positioning device 120 is independent from the loading areas 11 and from the guided trajectories for transportation 110 in order to prevent the transmission of vibrations. Results carried out by a machine 10 like those of
In the machine 10 of
Due to this configuration able to rotate around the loading rotation axis 72, the mannequins 1 can adopt a special loading position C which is very comfortable for the operator, wherein the trousers can be loaded onto a mannequin 1 folded around the rise of the pair of trousers, with the trouser legs almost or practically on top of each other (which we do when folding a pair of trousers lengthwise, around the axis of symmetry of the pair of trousers), by being able to arrange the front planes 23 of the two leg structures 2 of a mannequin by forming a small acute angle of about 20° for example, according to the capacity thereof to rotate around the main rotation axis 5. Furthermore, by the mannequin 1 being able to tilt around the loading rotation axis 72, horizontal and perpendicular to the main rotation axis 5 of the mannequin 1, the mannequin 1 can be arranged with the front 23 and rear 24 planes of the leg structures 2 thereof in inclined planes, not vertical ones and the lower ends of the leg structures 2 from whence the mannequin 1 is dressed with the pair of trousers, are higher and are further forwards than the rest of the mannequin 1, for which reason the operator loading the mannequin 1 does not have to bend over in order to introduce the pair of trousers.
In this manner, the operator does not have to load the pair of trousers in the habitual position thereof, with the waist extended and bending over in order to pass underneath the pair of trousers, but rather the mannequin 1 can be arranged in the special loading position C thereof, with the front planes 23 forming an acute angle and in a position wherein said planes are inclined with respect to the vertical plane v, being able to load the pair of trousers folded along and from a height comfortable for arranging the lower portion of the mannequin 1 at the height of their hands when the operator is standing.
It is also envisaged that in the marking area 12, descending forced ventilation means (not shown in the drawings) are provided for the extraction through the lower portion of the machine 10 of the gases originating from the laser heating the inks of the pair of trousers during the marking.
The auxiliary device for loading and/or unloading 90 comprises a plurality of waiting supports 9, 9′, made up of pairs of oblong waiting profiles 9a and 9b, arranged radially and inclined in a descending direction towards the centre, as if they were the petals of a flower. The waiting profiles 9a and 9b of one same pair are parallel to each other, are separated by a short distance and have a length such that they receive the insertion of the two legs of a pair of trousers in the position folded around the rise line of the pair of trousers. By way of example, a waiting support 9 or 9′ can be configured as a U-shaped fork, the arms of which are the waiting profiles 9a and 9b. Precisely the short distance separating the waiting profiles 9a and 9b is so that there is a space to place the two inner faces of the trouser legs which stay facing each other when the pair of trousers is folded.
The auxiliary device for loading and/or unloading 90 also comprises an introducing arm 91 made up of an inclined guide rail facing one of the waiting supports 9′ of the plurality of supports 9. The introducing arm 91 is arranged above said waiting support 9′, the length of the guide rail being such that it protrudes above the cited waiting support 9′, the upper end thereof being located at the same level or a higher level wherein the upper areas 21 of the leg structures 2 of the mannequin 1 located in the loading area 11 are located. The introducing arm 91 is provided with pushing projection means 92 slidable along the guide rail and which protrude, with respect to the guide rail towards the waiting support 9′, a distance such that the pushing projection means 92 are able to push a pair of trousers arranged folded over the waiting support 9′ and move it along the guide rail to the upper end thereof.
In order to make use of the auxiliary device for loading and/or unloading 90 to automatically load a pair of trousers on the mannequin 1, the first thing is to arrange a waiting support 9′ wherein a folded pair of trousers is supported and that this waiting support 9′ is facing the introducing arm 91. A mannequin 1 free of trousers must also be placed, in the loading position C in order to receive a folded pair of trousers activating the suitable means, arranging the front planes 23 of the leg structures 2 in non-vertical planes, and specifically, with the same inclination of the introducing arm 91. The two lower areas 22 of the leg structures 2 of the mannequin 1 will be arranged after the respective waiting profiles 9a and 9b which make up the waiting support 9′, aligned with them. The pushing projection means 92 will start the ascension thereof and will push the folded pair of trousers carrying it upwards by the joining area of the trouser legs. As the pair of trousers is dragged upwards, the pair of trousers will start to leave the waiting support 9′ and will enter the leg structures 2 of the mannequin 1 until the mannequin 1 of the loading area 11 is dressed. Afterwards, when the transfer of the mannequin 1 together with the transportation cart 71 thereof is activated, and passes along the cam profile located in an area of the rail, the lower areas 22 of the leg structures 2 will lower bit by bit and the mannequin 1 will be arranged with the front planes 23 in vertical planes and will be transported to the marking area 12.
Alternatively or additionally, the pushing projection means 92 can be provided with gripping elements such as for example clamps, which grip the waist of the pair of trousers by two segments and in this manner by sliding along the introducing arm carry the pair of trousers to the upper areas 21 of the leg structures and once there they release it so that the pair of trousers goes to the maximum tensed end position B.
It is also envisaged that the already-marked trousers can be unloaded in the same auxiliary device for loading and/or unloading 90 in the free waiting supports 9. An operator can be monitoring the automatic loading and also assisting the unloading of the trousers in the waiting supports 9. In this manner the auxiliary device for loading and/or unloading 90 is taken advantage of, the yield of the operator operating the automatic loading is optimised so that they also take care of the unloading, and the plant floor is optimised using a single auxiliary device for loading and/or unloading 90 also as an unloader. Another option would be to unload the marked trousers in a second auxiliary device for loading and/or unloading 90 exclusively dedicated to receiving marked trousers.
Alternatively to the flower configuration of the auxiliary device for loading and/or unloading 90 of the drawings, according to other embodiments the waiting supports 9 could adopt a roundabout-type configuration or more fanciful shapes but which likewise enable the different work steps or stations to be established: the manual loading of the trousers in the auxiliary device for loading and/or unloading 90, the automatic loading of the trousers from the auxiliary device for loading and/or unloading 90 to the mannequin 1 and vice versa, and the unloading of the already-marked trousers, manually or automatically, from the auxiliary device for automatic loading and/or unloading 90. Thus, the waiting supports 9 and 9′ are arranged inclined and cantilevered, they have the upper ends thereof free and the lower ends thereof are coupled to movement means by which the waiting supports 9, 9′ are movable with respect to the support base and in a guided manner according to a trajectory which can have any shape, while it goes underneath the introducing arm 91. In the movement thereof along said trajectory, a moment will arrive in which each of the waiting supports 9 goes underneath the introducing arm 91, becoming the waiting support 9′ upon reaching that point of the trajectory. In that point the inclination of said waiting support 9′ will be arranged parallel to the inclination of the introducing arm 91 and the pushing projection means 92 will protrude from the guide rail in the separation space between the two waiting profiles of the waiting support 9′ located beneath it.
Finally, apart from the distribution shown in
Thus, it is clear that the auxiliary devices for loading and/or unloading 90 can be used not only for loading trousers but also for unloading. A machine 10 can be attached to an auxiliary device for loading and/or unloading 90 full of folded trousers in the waiting supports 9, from which the mannequins 1 of the loading area 11 are loaded, and another empty auxiliary device for loading and/or unloading 90, in an unloading area (not shown in the drawings) wherein the mannequins 1 in the special loading position C, which is the same position adopted by the mannequins in the unloading position, are once again within reach of the pushing projection means 92 which hook or grip the marked trousers and start to place them in the waiting supports 9.
