Definitions

  • This invention relates to a unit for stacking slats on a support structure for the production of Venetian blinds and a method of positioning a support structure in a unit for stacking slats of a Venetian blind.
  • Venetian blinds are constituted by a plurality of slats, arranged parallel to each other and maintained in position by string support structures. These structures are essentially of two types: “complete ladder” (more simply “ladder”) or “separate ladders” (more simply “semi-ladder”).
  • a support structure of the "ladder” type is constituted by two parallel ribs (arranged in the direction of the height of the blinds) and a plurality of crosspieces that connect them to each other at regular distances.
  • a slat is associated to each crosspiece, supported (if the crosspiece is single) or inserted (if the crosspiece is double or multiple). Therefore, the two ribs serve as uprights for the slats.
  • a support structure of the "semi-ladder" type is constituted by two cords separated from each other and each provided with a plurality of string eyelets, distributed at regular distances along the single cord.
  • the support cords are positioned in pairs on opposite sides of the slats, generally transversely aligned.
  • the cords are associated to the slats at the eyelets, in particular using clips or hooks fastened on the side edges of the slats themselves. Therefore, the two cords serve as uprights for the slats.
  • Both types of support structure are similar in that they both have uprights, to which are associated the means of attachment of the slats, constituted by the crosspieces (single or double) in the case of the ladder or by eyelets in the case of the semi-ladder.
  • the support structure must be positioned with respect to the slat in such a way that the each of the uprights are located on one of the two sides of the slat itself.
  • a Venetian blind is realised by associating a plurality of slats to two or more support structures spaced longitudinally from each other.
  • this operation is automated using production systems that comprise two or more stacking units along a slat sliding line.
  • each stacking unit is suitable to position a support structure on a plane transverse to the slat sliding line, with the two uprights arranged laterally to the slats.
  • the slats are associated to the support structure, they are progressively stacked one on another in a storage area for the slats already worked. With this movement, they jerkily drag with them the entire support structure associated with them.
  • the positioning of the crosspieces or eyelets is linked to the movement imposed on the entire support structure by the progressive displacement of the slats from the working plane to the storage area for the slats already worked.
  • this method of moving the support structure is not always able to ensure a correct positioning of the crosspieces or eyelets with respect to the working plane of the slats.
  • the dimensional tolerance in the distribution of eyelets and crosspieces is such as to significantly affect the final positioning of these elements.
  • a support structure (whether ladder or semi-ladder) is not rigid and is therefore subject to movements, tensions or slackening that, in fact, affect the actual position of the eyelets and crosspieces.
  • two uprights of the same support structure may be subject to different tensions in the same stacking unit. This is inevitably reflected in the position of the crosspieces and eyelets with respect to each other and the working plane.
  • the purpose of this invention is to wholly or partly eliminate the drawbacks of the prior art cited above, by providing a slat stacking unit on a support structure for the production of Venetian blinds that allows the controlled positioning of this supports structure with respect to a slat working plane in such a way that the final position of the eyelets or crosspieces about to be associated with a slat is not affected, or not significantly, by the dimensional tolerances of the support structure and/or by any tensions applied to the structure itself.
  • a further purpose of this invention is to make available a slat stacking unit that can operate without distinction with support structures of the ladder and semi-ladder type.
  • a further purpose of this invention is to make available a slat stacking unit that is simple to manage.
  • a further purpose of this invention is to make available a slat stacking unit that is simple and economical to produce.
  • a further purpose of this invention is to make available a method of positioning a support structure in a unit for stacking slats of a Venetian blind that allows the controlled positioning of the support structure in such a way that the final position of the eyelets or crosspieces about to be associated with a slat is not affected, or not significantly, by the dimensional tolerances of the support structure and/or by any tensions applied to the structure itself.
  • the reference number 1 indicates, in its entirety, a slat stacking unit on a support structure for the production of Venetian blinds according to the invention.
  • the stacking unit 1 is intended to be inserted - together with one or more identical units - in a more complex production system (not shown in the figures). More in detail, the unit 1 may be movably associated with a longitudinal support bar (not shown) at one end of which is arranged a slat production machine (not shown).
  • the support structure S with which the stacking unit 1 works is provided with two uprights P1,P2 and a plurality of connection elements T1,T2 to the slats, attached to the uprights and distributed along the longitudinal extension of the latter.
  • the support structure S can be of the ladder type, in which the two uprights are connected to each other by crosspieces (single, double or multiple) that constitute the connection elements to the slats.
  • the support structure S can be of the semi-ladder type (as shown, for example, in the accompanying figures), in which the two uprights are separated from each other, each provided with a plurality of eyelets that constitute the connection elements to the slats.
  • the slat stacking unit according to the invention is thus suitable to operate without distinction with support structures of the ladder or semi-ladder type.
  • the stacking unit 1 comprises at least one guide element (not shown) for a slat L, which defines a working plane m on which the slat L slides supported along a longitudinal axis of movement X.
  • this guide element is constituted by a laminar element rigidly secured to a support structure of the stacking unit 1.
  • the slat is associated to connection elements T1,T2 of a support structure S positioned on a positioning plane p incident to the working plane m, with the two uprights positioned on two opposite sides of the longitudinal axis X.
  • the stacking unit is provided with devices for associating the slats L to the connection elements of the support structure S. These devices may be of any type provided they are suitable for the purpose. They are not described here since they do not constitute the core of this invention and are, in any case, known to a person skilled in the art.
  • association devices of the slats to the eyelets of the uprights can be those described in European patent application No. EP EP2653646A2 filed in the name of the same Applicant and incorporated herein by reference.
  • association devices of the slats to the crosspieces of the uprights may comprise, for example, divaricating means of the crosspieces, well known to a person skilled in the art.
  • the stacking unit 1 comprises means 20 for positioning the support structure S on such a positioning plane p incident to the working plane m, in such a way that the two uprights are arranged on two opposite sides with respect to the longitudinal axis X.
  • the support structure S is made to slide on the positioning plane p along a sliding direction Q incident to the working plane m.
  • the positioning means 20 comprise in particular two guides 21,22, spaced from each other to receive each one of the two uprights P1,P2 of the support structure S.
  • the connection elements T1,T2 of the structure S are progressively arranged as the support structure slides along the sliding direction Q, in such a way as to be accessible for the operations of association to the slats.
  • each guide 21,22 has a limited longitudinal extension along the sliding direction Q and terminates in the vicinity of the working plane with an upper end 21',22'.
  • the stacking unit comprises means 30,40 for moving the two uprights P1,P2 of the support structure S independently of one another making them slide parallel to the above-mentioned sliding direction Q incident to the working plane m.
  • these moving means 30,40 are controlled, preferably by an electronic control unit (not illustrated in the accompanying figures), so as to progressively position the connection elements T1,T2 of each upright exactly in correspondence of the working plane m.
  • connection elements are in the required position so that they can be properly associated with the slat. This position depends on the characteristics of devices intended to carry out such operations. The adaptation is within the reach of a technician in the field, by merely deciding the position in which the connection element is to be stopped depending on the operational needs of the devices actually used.
  • the independent and controlled movement of the two uprights of the support structure is able to ensure a correct positioning of the crosspieces or eyelets (i.e., the connection elements) with respect to the working plane of the slats.
  • this positioning method is not affected by dimensional tolerances in the distribution of eyelets and crosspieces, as it allows a very accurate local positioning.
  • the positioning method according to the invention is not even significantly affected by the "non-rigidity" of the support structure and by any movements, tensions or slackness to which they may be subjected.
  • the independent positioning of the two uprights allows remedying any differentiated tensions between the two uprights.
  • the independent positioning of the two uprights may interfere with the operation of the stacking unit, determining offsets on the sliding movement of the uprights and therefore of the support structure, and thus jams.
  • the independent positioning is a guarantee with respect to such events.
  • the independent positioning allows continuously, and in a controlled manner, correcting any errors in the initial loading of the support structure, in particular in the case of semi-ladders, in which the two uprights are physically separated.
  • the independent positioning operates on support structures in which the connection elements (eyelets and crosspieces) are realised with a substantially regular pitch. Therefore, the intervention of the moving means is essentially corrective and does not oppose to the normal operation of the stacking unit. In any case, the elasticity of the uprights is able to absorb any unevenness between one side and the other with a compensation effect, even during working when one or more slats are already associated to the structure.
  • the invention therefore allows precisely and constantly controlling the positioning of the eyelets and crosspieces, significantly increasing the quality of the final product. This happens in the case of both ladder structures and semi-ladder structures.
  • the moving means 30,40 comprise at least two distinct releasable gripping elements 31, 41, constituted for example, by controllable grippers able to clamp the uprights.
  • gripping elements 31,41 are moveable parallel to the above-mentioned sliding direction Q, independently from one another, on opposite sides with respect to the longitudinal axis of movement X.
  • the two gripping elements 31,41 preferably operate in correspondence with the positioning plane p of the support structure so that each gripping element 31,41 can engage an upright P1,P2 of the support structure.
  • each gripping element 31,41 is functionally associated to least one sensor 32,42 suitable to detect the position of the connection elements T1,T2 of the respective upright P1,P2 in relation to the working plane m.
  • the movement of each gripping element 31,41 is controlled by the respective sensor 32,42 through, for example, the above-mentioned control unit, which receives input signals from the sensors and is programmed to control and actuate the gripping elements.
  • the above-mentioned at least one sensor 32,42 preferably optical, is arranged below the working plane m at a predefined distance.
  • the movement of the gripping element 31,41 is controlled in such a way that, after the detection of the passage of a connection element by the respective sensor 32,42, the gripping element 31,41 is stopped after having covered a further section equal to the predetermined distance.
  • each gripping element 31,41 moves parallel to the above-mentioned sliding direction Q between a gripping start position ( Figs. 3 , 4 and 8 ) and a gripping end position ( Fig. 5 ) in a cyclical manner, alternating going and return movements.
  • the gripping element grips the respective upright so as to drag it with itself, while in the opposite return movement ( Figs. 5-8 ) the gripping element does not grip the upright, leaving it stopped.
  • each gripping element 31,41 is slidingly associated with a guide bar 33,43 that extends parallel to the sliding direction Q.
  • each gripping element 31,41 is moved away from the respective upright P1,P2 to avoid accidentally touching the connection elements and/or the edge of the slats (see Figs. 6-7 ).
  • the gripping element 31,41 may be slidably associated to the guide bar 33,43 by means of a carriage 34,44.
  • the gripping element is movably associated with the carriage so as to move transversely with respect to the carriage itself and thus to the guide bar and be able to thus move away from the upright during the return movement.
  • the stacking unit 1 comprises, for each upright P1,P2, blocking means of the movement of the uprights themselves.
  • these blocking means are deactivated during the going movement of the gripping element, while they are activated at least during the return movement to prevent the upright - in the absence of the action exerted by the gripping element - to move from the position in which it was carried.
  • the blocking means can be constituted by pawls arranged on the guides 21,22 and actuated by pneumatic or hydraulic pistons, whose intensity of intervention is controllable. As a function of the intensity of actuation of the pistons, the pawls can brake the sliding of the upright or block it completely.
  • each of the guides 21, 22 - which are part of the positioning means 20 - is formed so as to wrap the portion of upright that is inserted in it, letting it project to the outside substantially only the related connection elements T1,T2.
  • each gripping element 31,41 grips the respective upright in a section not covered by the guide 21,22 beyond the upper end 21',22' and thus above the working plane m. In this way, there is no risk that the movement of the gripping elements being obstructed or limited by the steric encumbrance of the guides.
  • the stacking unit 1 comprises a loader 10 in which the slats are deposited with a movement along the above-mentioned sliding direction Q, after being associated to the support structure S.
  • the movement of the slats into the loader 10 is performed by lifting means 50, specifically dedicated to that function.
  • the loader 10 defines a storage compartment 10a,10b for slats placed above the working plane m.
  • the lifting means 50 are suitable to lift the slats from the working plane m to the storage compartment 10a,10b.
  • the lifting means 50 are controlled by the already mentioned electronic control unit.
  • the moving means 30,40 of the uprights impose a movement to the uprights P1,P2 concordant with that of the slats L, i.e., substantially parallel to the sliding direction Q.
  • the loader 10 is formed by two first vertical support bars 11,12, arranged on two opposite sides with respect to the longitudinal axis of movement X.
  • the slats L are inserted between the two bars 11,12 and supported in position by at least one pair of retractable brackets 13,14 formed by two brackets placed at the same level, of which a first bracket fixed to one bar and a second bracket fixed to the other bar.
  • Each pair defines a storage area.
  • the brackets suitable to define a stable support area for the slats, are of the retractable type if subjected to a push from below, so as to eliminate their encumbrance.
  • These retractable brackets are equipped with an automatic system for return to the active position, for example based on elastic means.
  • the position of each bracket 13,14 is adjustable in height along the respective bar 11,12 by means of an adjustment hand wheel 36,46.
  • the storage area is divided into a temporary storage area 10a and a final storage area 10b formed on different levels.
  • the temporary storage area 10a is formed at an intermediate level between the working plane m and the final storage area 10b.
  • the temporary storage 10a temporarily stores each slat L as soon as it is associated to the support structure S before being moved to the final storage area 10b, where it is placed alongside any other slats that may be present and already associated to the support structure S.
  • the temporary storage area 10a receives the slat just associated to the support structure.
  • a slat is held in the temporary storage area until a new slat is associated to the support structure.
  • the slat in the temporary storage area 10a is moved to the final storage area 10b, where all the worked slats are progressively stacked.
  • the temporary storage area is freed, it is possible to place a new slat in it.
  • the two movements take place simultaneously in a synchronised manner.
  • the slats are overlapped on one another in a compact configuration.
  • a technician of the field knows that, in some cases, due to incorrect positions assumed by the uprights during previous processing steps, it may happen that the uprights end up moving towards the inside of the support structure, thus positioning themselves between one slat and another one.
  • This incorrect positioning of the uprights in addition to not allowing a correct overlapping between the slats in the loader, may impart a shape memory to the uprights themselves, such that during use they will tend to resume this incorrect position, at the expense of functionality and of aesthetics of the Venetian blind.
  • the stationing of the slat in the temporary storage area allows to physically separating the step of working slat, during which the slat is associated to a portion of the support structure, and step of storing the worked slat, in which the slat is placed next to the previously worked slat and the uprights assume the typical S-shape.
  • the slat is not then immediately placed next to the previous slat, but is left stationed in the temporary storage area.
  • the uprights could have tensions related to the operations of associating the slats.
  • a part of each upright is inserted inside the respective guide, while the remainder is disposed outside of the guide.
  • the temporary storage area 10a is formed at a higher level than the upper end 21' or 22' of each guide 21,22 of the positioning means 20 of the support structure S.
  • each storage area 10a,10b is defined by a pair of brackets, associated with the two first bars 11,12 and retractable inside the respective bar, if subjected to a push from below.
  • the position of each bracket 13,14 is adjustable in height along the respective bar 11,12 by means of an adjustment hand wheel 36,46.
  • the first two vertical bars 11,12 are positioned on a plane parallel to and distinct from the positioning plane p of the support structure S.
  • the lifting means 50 of the slats comprise first and second lifting elements 51 and 52, movable parallel to said sliding direction Q respectively on two opposite sides of said longitudinal axis of movement X.
