    LIFT FOR BUILD-IN IN A LIFTING DEVICE OF ONE
    JACQUARD MACHINE
    This invention relates to a hoist for installation in a hoist device of a Jacquard machine, comprising - a shaft; - a housing, comprising two flank bodies, which are provided for fixing the shaft, so that this shaft mainly extends between the flank bodies and so that the flank bodies are axially secured by means of the shaft in both axial directions; and a pulley wheel, which is provided for being rotatably arranged directly between the two flank bodies about the axis.
    In addition, this invention relates to a hoist device for a Jacquard machine which comprises a hoist according to the present invention.
    Furthermore, this invention also relates to a Jacquard machine, which comprises a hoist device according to the present invention.
    As described for example in WO 2014/076558 A2, Jacquard machines are used to bring the warp threads in a weaving machine into the correct position per weaving cycle in order to achieve a desired binding with a desired pattern in combination with the weft threads.
    Bringing the warp threads into the correct position is done with the help of hoist devices. In such a hoist device, a hoist is provided with an upper and a lower hoist wheel. Examples of such hoists are known, for example, from CH 380 046 A, CN 203 229 633 U, EP 0 526 820 A1 and CH 367 452 A.
    Such hoist devices are used, for example, in Jacquard machines for moving the warp threads of single-piece flat weaving machines. An upper hoist cord is then wrapped around the upper pulley wheel, which is provided with two corresponding hooks (complementary hook set), which can selectively move, for example in reverse phase, with two corresponding knives, the movement of the corresponding hooks via the upper pulley cord being transferred to a rotation of the upper pulley wheel. By influencing the hooks with the aid of one or more associated selectors, for example electromagnetic selectors, the hooks are held in their upper or lower position (depending on the embodiment) for the duration of one or more weaving cycles. Around the lower pulley wheel is a lower pulley cord which is connected at one end to one or more levers, which are provided with an opening (lever eye) through which a warp thread runs to adjust the position of this warp thread. Such a siphon is sprung, while the other end of the lower pulley is held in a well-defined position in the Jacquard machine.
    A similar hoisting device is used in multi-gripper weaving machines, which are provided to allow the insertion of more than one weft at different weft insertion levels per weaving cycle. The associated hoisting device can then comprise several hoists and / or additional reversing wheels.
    In view of the increasing trend to weave fabrics with higher densities and / or to provide more colors in a fabric, increasingly stringent requirements are placed on Jacquard machines regarding the number of hoists that can be accommodated in a Jacquard machine for the same volume. All solutions to make a Jacquard machine more compact are therefore of particular importance. To achieve this, the hoists are preferably designed to be as light and as cheap as possible, while still being able to withstand as much load as possible per unit volume.
    Various hoists have already been developed for this purpose.
    In a first known compact hoist, the hoist wheels are formed by casting a plastic wheel disc around a central upright flange of a metal axle. This upright flange, which is centrally provided on the metal shaft, thus forms the core for the pulley wheel. Two flank bodies which form a housing for this hoist are provided with recesses in which the ends of the shaft are rotatably arranged, so that the shaft with the pulley wheel attached centrally thereto is rotatably arranged with respect to these flank bodies. However, the flank bodies must be sufficiently rigid for this purpose.
    In a second, even more compact, known hoist - with all the features according to the introductory part of the first claim - the metal shafts are therefore clamped in recesses of the flank bodies, wherein plastic pulley wheels are rotatably arranged around these shafts. Thanks to the clamping, the flank bodies are also axially locked in this way by the shafts. The flank bodies cannot be moved outwards or inwards at the ends of these axles in the hoist, because the clamping with the axles prevents this. Due to this axial securing, these flank bodies themselves can be made less rigid and therefore more compact and / or lighter and / or cheaper or this hoist can have a longer lifespan for the same compactness.
    The object of this invention is to further increase the compactness of such a hoist or to further increase the service life of such a hoist at the same compactness.
    This object of the invention is achieved by providing a hoist for installation in a hoisting device of a Jacquard machine, comprising - a shaft; - a housing, comprising two flank bodies, which are provided for fixing the shaft, so that this shaft mainly extends between the flank bodies and so that the flank bodies are axially secured by means of the shaft in both axial directions; and a pulley wheel, which is provided for being rotatably arranged directly between the two flank bodies about the axis; wherein the shaft is provided with cavities and / or projecting portions for axially locking the flank bodies.
    In order to realize the axial securing of the flank bodies by the shaft in the above described hoist according to the prior art, the clamping of the shaft in the flank bodies must be realized over a sufficiently large distance. According to this state of the art, the shaft is divided on its outside into a zone (operating section) around which the corresponding pulley wheel is rotatably arranged and a zone (holding section) that is clamped by the flank bodies.
    By now providing the shaft with cavities and / or projecting portions for axially securing the flank bodies, this holding portion on the outer circumference of the shaft can be considerably shortened or even eliminated, when the connection between the flank bodies and the shaft is no longer along the outer circumference of the shaft, but only through cavities with access openings at the ends of the shaft. In the latter case, only an internal holding portion is provided on the inside of the shaft and no longer a holding portion on the outer circumference of the shaft. However, there are also many embodiments according to the invention in which the holding portion is still only situated on the outer circumference of the shaft or partly on the outer circumference and partly on the inner side of the shaft.
    By limiting or eliminating the holding portion on the outside of the axle, the shafts for the same pulley wheels can be made shorter and the flank bodies can be made less rigid. Both parts (shafts and flank bodies) can be made lighter. The whole becomes more compact for the same pulley wheels. If the same compactness is assumed as with the prior art, a hoist with a longer service life can thus be obtained because the working part of the shaft can be enlarged relative to the holding part in comparison with the hoist of the prior art.
    The cavities and / or protruding parts of such a hoist according to the invention can take all kinds of forms, such as, for example, notches or constrictions in the outer circumference of the shaft, protrusions or thickenings on the outer circumference of the shaft, cavities centrally in the shaft with access openings on the shaft. ends of the shaft, which in turn can be further provided with notches, constrictions, bulges and / or thickenings, etc.
    Such a shaft can be made in one piece or in several parts so as to provide the necessary cavities and / or projecting portions.
    In a preferred embodiment of a hoist according to the present invention, the shaft comprises at its both ends an access opening to a said cavity in the shaft, and the flank bodies are provided for engaging the respective cavity via this access opening. In this way at least a part of the holding portion of the shaft can be provided internally in the shaft instead of externally. Preferably, such a shaft is then provided with a cavity extending through the shaft as said cavity. Even more preferably, such a shaft then comprises a uniform cross-section to considerably simplify its production. Such a shaft can then be produced, for example, by drawing or by extrusion. This can advantageously be manufactured from metal. Such hollow shafts with a small diameter (less than 3 mm, up to approx. 2 mm) are used in many sectors, including hydraulic applications, precision instruments, control equipment, etc. The high availability also guarantees the possibility to realize a high quality product in terms of material type, finish, roughness (Ra values up to a maximum of 0.4 μΜ), dimensions, etc., and this for an acceptable price.
    Such an axis with a uniform cross-section is further preferably embodied as a circular cylinder with a concentric cylindrical cavity.
    In a special embodiment of a hoist according to the present invention, the flank bodies are provided for force-tight clamping of the shaft.
    When a force-tight clamping is provided between the flank bodies and the shaft, the shaft is preferably provided at its both ends with an access opening to a said cavity in the shaft and for this purpose each flank body comprises a protrusion which is provided via the respective access opening to engage in the respective cavity to force-tighten the shaft.
    With a force-locked clamp on the inside of the axle instead of on the outside of the axle - as in the prior art - a larger part of the outside of the axle can be used as a working part for rotating a pulley wheel around it. . The shaft itself can be made lighter because it is hollow. The inside of the shaft is now also used, this as a holding part. The useful length of the shaft (internal and external) is therefore considerably greater. Particularly preferred, said projections of the flank bodies clamp this axis together over substantially the entire inner surface of the axis, so that the useful length of the axis is maximized.
    The said protrusions of the flank bodies can advantageously be made hollow. The cavity of these protrusions can provide cooling, or an additional clamping element can be provided in this cavity to realize a locking.
    In a specific embodiment of a hoist according to the present invention, the shaft is provided with a radial constriction as said cavity and / or with a radial thickening as said protruding part.
    It is also possible to provide an axle of a hoist according to the present invention with one or more local cavities and / or projecting portions such as said cavities and / or projecting portions. Because such local cavities and / or protruding parts are provided locally, they can also easily provide radial locking of the shaft without clamping. The flank bodies must then be provided with protrusions and / or cavities with a shape corresponding to the shape of these local cavities and / or projecting portions in the shaft.
    In a preferred embodiment of a hoist according to the present invention, the flank bodies are provided for radially locking the shaft. This radial locking can for instance be realized with a clamping or for instance as described above with the aid of local cavities and / or projecting parts in the shaft and corresponding protrusions and / or cavities in the flank body.
    The axle of a hoist according to the present invention can advantageously be connected to the flank bodies via press fit.
    In order to reduce friction between the shaft and the pulley wheel, the shaft is preferably provided with a coating. This coating is preferably a porous coating, so that the ash can retain lubricant even better thanks to this coating.
    The pulley wheel and the flank bodies are preferably provided with respective grooves and ribs which together form a labyrinth seal in order to better retain lubricant.
    The shaft preferably further has a higher wear resistance than the pulley wheel.
    The pulley wheel is preferably made from plastic.
    The housing of a hoist according to the present invention is also preferably made of plastic. The lighter and less rigid flank bodies can be made from a cheaper plastic.
    The housing is prefabricated by injection molding. This also allows for a cheaper choice of material, since injection molding of less efficient plastics is easier and faster.
    At least one flank body of a hoist according to the present invention preferably comprises a groove for securing a hoist cord wrapped around the hoist wheel. This groove preferably extends transversely of the longitudinal direction of the shaft over the entire flank body and thereby preferably extends from one side of the flank body to the opposite side thereof. This groove preferably takes the same curved shape in which the pulley cord is wrapped around the pulley wheel.
    The housing of a hoist according to the present invention is furthermore preferably constructed in two parts, wherein each flank body forms part of a respective part of the two-part housing. This allows a smooth assembly of the hoist.
    The two parts of the two-part housing are preferably substantially identical, so that swapping both parts does not affect the assembly.
    These two parts of the two-part housing are furthermore preferably mutually connected by means of a press fit and / or a snap connection, so that mounting is possible without gluing, heating or additional fixing means, etc.
    The object of this invention is additionally achieved by providing a hoist device which comprises a hoist according to the present invention as described above.
    Furthermore, the object of this invention is also achieved by providing a Jacquard machine which comprises such a hoist device according to the present invention.
    The present invention will now be further elucidated with reference to the following detailed description of an embodiment of a hoist according to the present invention. The purpose of this description is only to provide clarifying examples and to indicate further advantages and details of this hoist, and therefore cannot be interpreted as limiting the scope of the invention or the patent rights claimed in the claims.
    In this detailed description reference is made to the accompanying drawings by reference numerals, wherein in Figure 1 a hoisting device is shown with a hoist; figure 2 shows a special embodiment of a hoist according to the present invention in sketchy perspective; figure 3 shows an axis of a first specific embodiment of a hoist according to the present invention in sketchy longitudinal section; figure 4 shows a part of the first specific embodiment of a hoist according to the present invention in sketchy section, at the height of an axis, the axis being cut longitudinally; figure 5 shows a part of a variant of the first specific embodiment of a hoist according to the present invention in sketchy section, at the height of a hoist wheel and the connection between two flank bodies; figure 6 shows an axis of a second specific embodiment of a hoist according to the present invention in sketchy longitudinal section; figure 7 shows a part of the second specific embodiment of a hoist according to the present invention in sketchy view, at the height of an axle; figure 8 shows the part of the second specific embodiment of figure 7 in sketchy section, at the level of the axis, the axis being cut longitudinally; figure 9 shows a part of a third specific embodiment of a hoist according to the present invention in sketchy section, at the height of an axis, the axis being cut longitudinally, before the flank bodies are connected to the axis via presses; figure 10 shows the part of the third specific embodiment of figure 9 sketchy in section after the flank bodies are connected to the shaft via presses, - figure 11 a part of a fourth specific embodiment of a hoist according to the present invention is shown in sketchy section at the height of an axis, the axis being cut longitudinally.
    A Jacquard machine according to the invention comprises at least two rows of hooks (24) and at least two knives which each move up and down opposite a row of hooks (24) and take or not take with them the corresponding hooks (24).
    Figure 1 shows two hooks (24), each of which forms part of a respective row of hooks (24). These two hooks (24) form a so-called hook set.
    As shown in Figure 1, these two hooks (24) are connected to an upper pulley cord (2), which is wrapped around an upper pulley wheel (6) of a pulley (1). A lower pulley (2 ") is wrapped around the lower pulley wheel (6") of this hoist (1). This lower pulley cord (2 ') is connected at one end to one or more levers (23), which are provided with an opening (lever eye), through which a warp thread (22) runs, to adjust the position of this warp thread (22 ). Such a siphon (23) is sprung (25). At a second end, the lower pulley (2 ") is held in a well-defined position (26) in the Jacquard machine. This position (26) can be a fixed position, or can be adjustable, for example with the help of a control profile. The height of the siphon eyes of the jacquard levers (23) can be adjusted via the control profile without having to adjust the height of the entire Jacquard machine.
    By moving the hooks (24) the position of the hoist (1) is also changed via the upper hoist cord (2) and this also changes the position of the lever (23) via the lower hoist cord (2 "). In this way the warp thread (22) provided therein can be brought into a desired position to realize a desired bond with a desired pattern with the weft threads (21).
    In addition to the parts shown in Fig. 1, a hoisting device can also comprise other parts, such as, for example, reversing rollers, around which a hoist cord (2, 2 ') is laid, harness cords, etc.
    The hoist (1) from this hoist device comprises the said hoist wheels (6, 6 '), each of which is rotatably arranged around a shaft (3).
    The hoist (1) further comprises flank bodies (5) which are arranged on either side of the hoist wheels (6, 6 ') and which form part of a housing (4) for the hoist (1). These flank bodies (5) can, as can be seen in figure 2, be provided with wings (12) extending between the pulley wheels (6, 6 ') around a cord (2) wrapped around a pulley wheel (6, 6') better to conduct. These wings (12) can optionally also be provided as separate parts of the housing (4).
    The shafts (3) and the flank bodies (5) are mutually connected in such a way that the shafts (3) secure the flank bodies (5) axially. To this end, the shafts (3) are provided with cavities (7, 10, 11) and / or protruding portions, examples of which are given below with some specific embodiments.
    The shafts (3) of a hoist (1) according to the invention preferably have a higher wear resistance than the hoist wheels (6, 6 ').
    The shafts (3) can preferably be made of metal for this purpose. This can advantageously be a material that is also used, for example, in hydraulic applications, in precision instruments, in control equipment, etc., so that its availability is large and a high-quality product can therefore be realized for a limited cost. More specifically, for example, stainless steels from the AISI 300 series such as AISI type 302, 304, 310, 316, ... are preferably in a state indicated by "full hard" suitable materials for such a shaft (3). Such a shaft (3) is preferably manufactured via a drawing process.
    In order to be able to retain lubricants better, such a shaft (3) is preferably provided with a porous coating. Such a coating can for instance be Tungsten disulfide.
    The pulley wheels (6, 6 ") are preferably made from plastic. One can think of polyoxymethylene (POM) or a nylon (PA6 or PA6.6), but polyether ether ketone (PEEK) can also be considered for a more sustainable solution. Lubrication additives such as graphite or teflon (polytetrafluoroethylene - PTFE) are preferably added to this plastic.
    In order to better retain lubricants, such a pulley wheel (6, 6 ") can also be provided with a labyrinth seal (14a, 14b), examples of which are further given in the specific embodiments.
    At its periphery, such a pulley wheel (6, 6 ') is preferably provided with a slot (13) as shown in Figures 2 and 5, to guide the pulley cord (2) wrapped around it.
    The housing (4) of a hoist (1) according to the invention is preferably manufactured from plastic. Polyamide 6.6, whether or not in combination with fiberglass, for example 30% fiberglass, is for instance a suitable material for such a housing (4), but other materials such as polyamide 6 and polyoxymethylene (POM) are also eligible as basic plastic.
    The housing (4) is prefabricated by injection molding. This allows a cheaper choice of material.
    At least one flank body (5) of a hoist (1) according to this invention preferably comprises a groove (15), as shown in the special embodiment in Figure 2, for securing a hoist wheel (6, 6 ') wrapped around it tackle cord (2, 2 '). This groove preferably extends transversely of the longitudinal direction of the corresponding axis (3) over the entire flank body (5) and thereby preferably extends starting from one side of the flank body (5) to the opposite side thereof. This groove preferably takes the same curved shape in which the pulley cord (2, 2 ") is wrapped around the pulley wheel (6, 6").
    The housing (4) is further preferably designed in two parts, wherein each flank body (5) forms part of a respective part of the two-part housing (4). The two parts of the two-part housing (4) are preferably substantially identical, so that swapping both parts does not affect the assembly. These two parts are furthermore preferably mutually connected by means of a press fit (27a, 27b) and / or a snap connection, so that mounting is possible without gluing, heating or additional fastening means, etc. In the embodiment shown in Figure 5, such an embodiment is press fit (27a, 27b) shown. To this end, the flank bodies (5) are provided with corresponding cavities (27a) and grooves (27b).
    Special features of the specific embodiments shown in Figures 3 to 11 are described below. In figures 4, 5 and 7-11, only a part of the hoist (6, 6 ") shown is shown at the level of the upper axle (3). The upper pulley wheel (6) is shown in section in each case in Figures 4 and 8-11 and the flank bodies (5) in each case are shown in section in Figures 4, 5 and 8-11. The pulley wheel (6) can be further elaborated in a known manner. The flank bodies (5) can be worked out at the bottom in a similar way as the depicted upper part of the flank bodies (5). For the sake of clarity, in Figs. 4, 8 - 11, the cross-sections of the flank bodies (5) and the associated housing (4) are shown unhatched. For the sake of clarity, the cross-section of the pulley wheel (6) is shown in FIG.
    In the first embodiment of a hoist (1) according to the invention shown in Figures 3 and 4 and in the variant thereof shown in Figure 5, the shaft (3) shown is a circular cylinder with a centrally concentric cylindrical cavity (7). The flank bodies (5) are each provided with a protrusion (8) which engages via the corresponding access opening (9) in the cavity (7) of the shaft (3), as can be seen in figures 4 and 5.
    As the cavity (7) of the shaft (3) extends through the shaft (3), and since the shaft (3) has a uniform cross-section, it can be produced in a particularly accurate manner by drawing or extrusion.
    The protrusions (8) of the flank bodies (5) which engage in the cavity (7) of the shaft (3) clamp the shaft (3) in a force-tight manner. For this purpose these protrusions (8) are arranged in the shaft (3) via a press fit. These protrusions (8) are shown in full in figures 4 and 5. However, these can also be made hollow, in order to provide cooling, or to be able to fit an extra clamping element therein to realize a locking.
    In the embodiment in Figure 4, the protrusions (8) of the flank bodies (5) extend into the cavity (7) of the shaft (3) at a distance from each other. In the embodiment in Figure 5, the protrusions (8) of the flank bodies (5) together extend over the full length of the cavity (7) of the shaft (3), the protrusions (8) of each other centrally in this cavity ( 7) touch.
    Thanks to the force-tight clamping, not only the flank bodies (5) are axially secured by the shaft (3), but also the shaft (3) is radially locked by the flank bodies (5), so that this shaft (3) cannot rotate with respect to the flank bodies (5).
    In the second embodiment of a hoist (1) according to the invention shown in Figures 6 to 8, the shaft (3) is provided on the underside with two notches (10), namely one per flank body (5). In each flank body (5) an elastic part (16) is provided, which can deflect elastically with respect to the rest of the flank body (5). This elastic part is provided at the top with a tooth (17) which can be fitted in the corresponding notch (10) in the shaft (3). The shaft (3) and the flank bodies (5) can thus be interconnected by means of a snap connection.
    By locking the tooth (17) of the elastic part (16) into the corresponding notch (10), the relevant flank body is axially secured by the shaft (3). Because the notch (10) is only provided on the underside of the shaft (3), the shaft (3) is thus also secured radially by the flank bodies (5).
    In this depicted second embodiment, a single notch (10) is provided per flank body. However, alternatively, several cavities (10) could also be provided per flank body (5), the flank bodies (5) being provided with corresponding teeth (17).
    In the third embodiment of a hoist (1) according to the invention shown in Figures 9 and 10, the shaft (3) per flank body (5) is provided with a radial constriction (11). The flank bodies (5) are, as can be seen in Fig. 9, provided with material (19) prior to their attachment, which, as can be seen in Fig. 10, after pressing are deformed into a radial rib (18) which is inserted into the corresponding radial constriction. (11). The radial ribs (18) formed in this way engage form-fittingly in the corresponding constrictions (11), so that the flank bodies (5) are axially secured by the shaft (3).
    Thanks to the pressing, a force-locked clamping is also realized, whereby the shaft (3) is also radially secured by the flank bodies (5).
    In an alternative embodiment, the shaft (3) can also be provided with a local cavity instead of the radial constriction (11) shown. It is thus also possible to provide several local cavities spread over the circumference of the shaft (3), into which material is pressed from the flank bodies (5) by means of pressing.
    In the fourth embodiment of a hoist (1) according to the invention shown in Figure 11, the shaft (3) is a first end in a manner analogous to that of the third embodiment illustrated with a radial constriction (11), in which a pressing engages radial rib (18) of the corresponding flank body (5), this with the advantages described above. At its other end, the shaft (3) is provided with a toothing (20), into which material of the corresponding flank body (5) also engages in a form-fitting manner. In addition to the radial securing by the pressing, the toothing provides an additional radial securing of the shaft.
    In figures 4 and 8-11 the pulley wheel (6) is each provided laterally with grooves (14a) in which a rib (14b) of the flank bodies (5) engages. These together form a labyrinth seal (14a, 14b) which is provided to hold lubricants in the space between the shaft (3), flank bodies (5) and pulley wheel (6). Such a labyrinth seal can also consist of several and / or more complex groove-rib combinations.
    The shafts (3) shown are each in one piece. These could alternatively also be carried out in multiparty, for example if this simplifies their production or if different properties are imparted to these parts with different materials.
    It is clear that in all embodiments involving cavities and / or constrictions in the shaft combined with protrusions of the flank bodies, corresponding embodiments are also possible in which projecting parts are provided on the shaft and cavities and / or constrictions in the flank bodies.
