    专利说明:

    The invention relates to a holder for a dip mold, which has a holding unit and a relative to the holding unit displaceable, acted upon by a spring pressure unit, wherein a portion of the dip mold between the at least one clamping projection and a pressing surface of the pressing unit can be clamped.
    Dipping forms are used in particular for the production of latex products, such as gloves. For transporting the dipping forms through various stations of a production line, conveyor chains are used with which the dipping forms are connected via a carrying device. The stations of such a production line include i.a. Dipping baths containing polymer materials, in particular natural or synthetic latex materials, in which the molds are immersed.
    Holders of the type mentioned above for immersion molding, for example, from WO 2015/142155 A1 and MY-163101 -A out. A respective holder has a holding unit which has a shank, at the front end of which protruding clamping projections are provided on opposite sides. On the shaft, a pressing unit is arranged displaceably, which is acted upon by a coil spring also arranged on the shaft. In order to mount a dipping mold on the holder, the pressing unit is pushed back against the force of the spring (by means of a special pneumatic pincer), whereupon a front end portion of the stem with the clamping projections can be inserted through an oblong opening in the bottom of the dipping mold. Subsequently, the dipping mold is rotated by 90 ° and the pressure unit is released, whereupon the bottom of the dipping mold between the clamping projections of the holding unit and a pressing surface of the pressing unit is clamped.
    The holder is supported by an L-shaped support arm, wherein the shaft of the holding unit relative to the support arm about the longitudinal central axis of the shaft is rotatable. For this purpose, two ball bearings are arranged on a rear end portion of the shaft, which are inserted into a bushing portion of the support arm.
    Two L-shaped support arms, which have the holder-carrying L-legs in opposite directions, are mounted together on a support shaft about a horizontal, parallel to the conveyor chain axis. Such support arms carrying support shafts are attached to the chain links at regular intervals on both sides of the conveyor chain.
    A disadvantage of prior art holder of the type mentioned is that the ball bearings which support the holding units rotatably relative to the support arms are exposed to a considerable wear. However, an exchange of such ball bearings requires an interruption of the operation of the system to perform the appropriate maintenance.
    The object of the invention is to provide an improved holder of the type mentioned. According to the invention, this is achieved by a holder having the features of claim 1.
    In the holder according to the invention, a connection unit for connecting the holder is provided with a support arm carrying the holder, wherein the connection unit has an axle pin on which the holding unit is rotatably mounted about a rotation axis.
    The connection unit may advantageously be adapted for connection to the socket portion of a conventionally formed support arm. An existing system is thus retrofitted in a simple manner with a holder according to the invention. The axle of the connection unit forms a rigid axle, on which a rotatable mounting of the holding unit is made possible with only a slight occurring wear.
    In an advantageous embodiment, bearing elements for rotatably supporting the holding unit may be provided on the axle pin of the connecting unit at the two ends of the holding unit.
    In a holder according to the invention, a relatively large distance between bearing elements for rotatably supporting the holding unit may be provided on the axle pin, whereby the moments acting on the bearing elements can be kept relatively small. In particular, the bearing elements may be plain bearing sleeves, which are inserted into a respective end portion of the penetrated by Achsstift passage opening through the holder. It is thereby a stable, low-wear and cost-effective training possible.
    The pressing unit is advantageously arranged on a shaft of the holding unit, through which the passage opening extends through the holding unit. In particular, the spring acting upon the pressing unit can be a helical spring arranged on the shaft, which is supported on the one hand on the pressing unit, on the other hand on a supporting part arranged on the shaft. This support member may be attachable in an advantageous embodiment by a plug-in rotary movement on the shaft, wherein locking elements of the shaft engage with counter-locking elements of the support member. This makes it easy to install and, if necessary,
    Dismantling possibility created. It is advantageously provided that a front end section of the holding unit, which has at least one clamping projection, can be inserted through an opening in a bottom of the immersion mold, wherein the bottom of the immersion mold can be clamped between the at least one clamping projection and the pressing surface of the pressure unit. Dipping forms of this type, which are formed in particular of ceramic, are usually used for the production of gloves.
    The holding unit and the pressure unit can advantageously be made of plastic.
    Further advantages and details of the invention are explained below with reference to the accompanying drawings. In this show:

    The figures have different scales.
    From a conveyor chain 1 for transporting immersion molds through various stations of a production plant for plastic gloves, in particular rubber gloves, a section is shown in FIG. The mentioned stations include i.a. Dipping baths in which the dipping forms are immersed, as is known.
    The immersion forms, not shown in Fig. 1 are supported by supporting devices, which are connected to the conveyor chain 1. These support devices comprise support shafts 3 connected to the link plates of the conveyor chain 1, support arms 5 carried by the support shafts 3 and supports 2 for the immersion forms carried by the support arms 5. For example, 1 attachment stub can be welded to the chain straps of the conveyor chain, on which the support shafts 3 are attached.
    At the free ends of the support shafts 3 are from these on opposite sides bearing pin 4 horizontally. The bearing pins 4 are in this case parallel to the longitudinal extent of the conveyor chain 1. On each of the bearing pin 4 is a here L-shaped support arm 5 is pivotally mounted about the longitudinal axis of the bearing pin 4. The support arms 5 are thus pivotable about horizontal, parallel to the longitudinal extent of the conveyor chain 1 axes.
    At the ends remote from the support shaft 3, the support arms 5 each have a bushing section 5a, which serves for connection to a respective holder 2.
    The immersion molds 7 held by the holders 2, which in particular are formed by ceramic molds, can be formed in a known manner. In Fig. 3 sections of the immersion molds 7 are shown in the region of their connection to the respective holder, in Fig. 4, the remaining part of a dip mold is shown schematically with dashed lines. Each of the immersion molds 7 has a bottom 7a, through which an elongated opening 7b leads into an inner cavity of the immersion mold 7, so that the bottom 7a of the immersion mold 7 is clamped to the holder 2 by means of clamping projections 14c, 14d of the holder inserted through the opening 7b can.
    Guiding means of the system cooperating with the holders 2 in a known manner are not shown in the figures. By means of rail-shaped guide means, which act on the holder 2, when the holders 2 are moved by means of the conveyor chain, the support arms 5 can be pivoted about their horizontal axes. The holders 2 roll in this case with a circle-shaped support surface 20a on the rail-shaped guide means, wherein the immersion molds 7 are rotated about axes of rotation 6, which lie ko with the longitudinal center axis of the socket portion 5a
    A respective holder 2 has a connection unit 8, via which it is connected to one of the support arms 5. For this purpose, a connection piece 8a of the connection unit 8 is inserted into the socket section 5a and held in the socket section 5a with a securing ring 10, which engages in a groove introduced in the inner wall of the socket section 5a. The connector 9 in this case has a support plate 9 a, which is supported on a bottom of the socket portion 5 a, and a clamp 9 b, which is inserted into the socket portion 5 a and whose outer peripheral contour is adapted to the inner peripheral contour of the socket portion 5 a and adapted to the Circlip 10 cooperates.
    The connecting piece 9 is preferably made of plastic, in particular an injection-moldable thermoplastic.
    With the connecting piece 9, an axle pin 11 is connected, which consists in particular of steel. For this purpose, the axle pin 11 is inserted into a through hole through the connecting piece 9 and a threaded portion 11 a of the axle pin 11 is screwed to a nut 12 made of metal, which is pressed into an end portion of the passage opening through the connector 9, the nut 12 by means of a a groove in the axle pin 11 snapped clips is secured against loosening. On the side facing away from the nut 12 side of the connecting piece 9 of the axle pin 11 is out of the connector 9 and forms a rigid axle for rotatably supporting a holding unit 14 of the holder 2. The holding unit 14 (with an attached to her immersion mold 7) is thus to the Rotary axis 6 relative to the connecting unit 8 and thus relative to the support arm 5 rotatable.
    The holding unit 14 has, for rotatable mounting on the axle pin 11, an e through opening 14a, which is penetrated by the axle pin 11. At the two ends of the holding unit 14 14 serving for rotatable mounting of the holding unit 14 on the axle pin bearing elements 15, 16 are provided. In the exemplary embodiment, these are plain bearing sleeves, which are inserted into a respective end section of the passage opening 14a through the holding unit 14.
    The holding unit 14 has a shank 14b on which clamping projections 14c, 14d are arranged in the region of its front end, that is to say remote from the connecting piece 9, which project radially beyond the shank 14b on opposite sides. For this purpose, in the exemplary embodiment, the holding unit has an end piece arranged on the shaft 14b (which is preferably formed integrally with the shaft 14b), which forms the clamping projections 14c, 14d.
    In the exemplary embodiment, the holding unit 14 thus consists entirely of plastic. It would also be conceivable and possible, for example, for the clamping projections 14c, 14d to be formed by a metal plate arranged on the shank 14b, which has sections projecting from the shank 14b on both sides.
    The clamping projections 14c, 14d serve to clamp the bottom 7a of the dip mold 7, as described in more detail below.
    To secure the holding unit 14 on the axle pin 11, a nut 17 screwed onto a threaded portion 11b of the axle pin 11 is made of metal. This is secured by an up to a groove of the axle pin 11 clip 18 against unintentional release. The nut 17 is pressed into a nut 19 made of plastic. By turning the nut 19, the nut 17 thus (after overcoming the resistance by the clip 18) are unscrewed from the axle 11, whereby the rotatably mounted on the axle 11 unit from the axle pin 11 can be removed, see. Fig. 7 and 8. This unit can be advantageously also taken apart, see the
    Description below.
    On the shaft 14b, a pressing unit 20 is arranged, which is against the force of a spring 21 formed in the form of a helical spring relative to the shaft 14b in the axial direction of the shaft (ie in the direction of the axis of rotation 6) displaceable. The spring 21 is supported at one end on the pressing unit 20 and at the other end on a supporting part 22. The support member 22 is also disposed on the shaft 14b and secured against displacement toward the fitting 9 by cooperating latch members 14e, 14f and counter latch members 22a, 22b, as described in more detail below. The support member 22 is preferably made of plastic.
    The rotatably mounted on the axle 11 unit thus comprises the holding unit 14, the pressing unit 20, the spring 21 and the support member 22. The rotatable mounting takes place by means of the already mentioned bearing elements 15, 16. A respective bearing element 15,16 simultaneously forms a radial bearing the axle pin 11 and a thrust bearing, which supports the rotatably mounted on the axle pin 11 unit in the axial direction of the axle pin 11. In this case, an axially aligned surface of the bearing element 15 cooperates with an end face, axially aligned surface of the connecting piece 9 (in the sense of a sliding bearing) and an axially aligned surface of the bearing element 16 cooperates with an end face, axially aligned surface of the nut 17 (in the sense of plain bearing).
    The pressing unit 20 has a cylindrical wall whose outer surface forms the cylinder jacket-shaped bearing surface 20a, with which the holder 2 can roll on a rail-shaped guide means. In the exemplary embodiment, the pressing unit 20 has a base part 20b made of plastic, which has the support surface 20a. The base part 20b is covered to the front by a cover plate 20c, wherein the base part 20b has a centering projection 20d, which passes through a window opening in the cover plate 20c.
    The operation of the holder 2 for holding a submersible mold 7 will be explained below with reference to FIGS. 9-21.
    9 to 13 show a basic state of the holder 2, which this occupies when - apart from gravity - no external force acting on the holder 2 and no immersion mold 7 is held by the holder 2. In FIGS. 12 and 13, that section of a dip mold 7, in which the attachment of the dip mold 7 to the holder 2, is additionally shown below the holder 2, is shown.
    In order to fix the immersion mold 7 on the holder 2, the pressure unit 20 is pushed back against the force of the spring 21, so that they are away from the clamping projections 14c, 14d, cf. 14 and 15, and the dip mold 7 is pushed with its opening 7b on the holding unit 14, so that the clamping projections 14c, 14d pass through the opening 7b in the bottom 7a in the interior of the dip mold 7, see. 16 and 17. In other words, a front end portion of the holding unit 14 having the clamping projections 14c, 14d is inserted through the opening 7b in the bottom 7a of the dip mold 7.
    The immersion mold 7 is rotated in the sequence by 90 ° about its longitudinal axis. The longitudinal axis of the dip mold 7 is in this case with the axis of rotation 6 of the holding unit 14 on a common line. The opening 7b of the immersion mold 7 can now be pushed onto the centering projection 20d of the pressure unit 20, whereby the bottom 7a of the immersion mold 7 comes into contact with the pressure surface 20e of the pressure unit 20, cf. Fig. 18.
    The pressing unit 20 is now released so that it is pressed by the spring 21 with the pressing surface 20e against the outside of the bottom 7a, which is pressed with its inside against the clamping projections 14c, 14d. In other words, the bottom 7a is clamped between the pressing surface 20e of the pressing unit 20 and the clamping projections 14c, 14d, cf. Fig. 19. The state which the holder 2 occupies when a submersible mold 7 is attached to it is also shown in Figs. 20 and 21 (for the sake of clarity, here without the immersion mold).
    The removal of the dipping mold 7 from the holder 2 takes place in the reverse order, i. First, the pressing unit 20 is pushed back against the force of the spring 21, then the dipping mold 7 is lifted from the centering projection 20d and rotated by 90 °, after which the holding unit 40 with the clamping projections 40c, 40d can be pulled out through the opening 7b in the bottom 7a.
    In the state attached to the holder 2, the immersion mold 7 is rotatable together with the holding unit 14 about the axis of rotation 6. The connecting unit 8 is in this case held non-rotatable relative to the support arm 5.
    The assembly of the pivotable mounted on the axle 11 unit comprising the holding unit 14, the pressing unit 20, the spring 21 and the support member 22 will be explained below with reference to FIGS. 22 to 31.
    22 to 25 show the state in which the pressing unit 20 and the spring 21 are pushed onto the holding unit, the support member 22 but only loosely rests on the remote from the pressing unit 20 end of the spring 21. The pressing unit 20 assumes its position as far advanced as possible, in which the centering projection 20d bears against the clamping projections 14c, 14d.
    On the shaft 14b of the holding unit 14 locking elements 14e, 14f are arranged, which are formed by radially outwardly projecting projections. In the exemplary embodiment, two locking elements 14e, 14f arranged on opposite sides of the shaft 14b are present.
    The support member 22 has counter-locking elements 22a, 22b, which are formed by radially inwardly projecting projections on the inner circumferential surface of the support member 22. In the exemplary embodiment, two opposing counter-locking elements 22a, 22b are present.
    In the illustrated in FIGS. 22-25 rotational position of the support member 22 are the locking elements 14e, 14f and counter-locking elements 22a, 22b at different angular positions with respect to the direction of rotation about the axis of rotation 6, so that they press the support member 22 against the force of the spring 21st can be passed by each other. The position of the parts in the passing state of the locking elements 14e, 14f and counter locking elements 22a, 22b is shown in FIGS. 26 and 27.
    As a result, the support member 22 is rotated by 90 ° (clockwise with respect to the rear view corresponding to FIG. 22). This position is shown in FIGS. 28 and 29. As a result, when the support member 22 is released, the counter-locking elements 22a, 22b come by the force of the spring 21 in abutment with the locking elements 14e, 14f and are pressed against this and the assembled state is prepared, in Figs. 30 and 31 is shown.
    Advantageously, the rotational position of the support member 22 in the assembled state by interengaging cams 14g and recesses 22c of the locking elements 14e, 14f and counter locking elements 22a, 22b secured.
    A disassembly of the unit can be done in the reverse order, ie first by pressing the support member 22, then rotation of the support member 22 by 90 ° (counterclockwise with respect to FIG. 22) and then releasing the support member 22nd
    Stop webs 22d, 22e on the inner circumferential surface of the support member 22 limit the pressing of the support member 22 and the rotation of the support member 22 relative to the holding unit 14th
    Due to the rotatable mounting of the holding unit 14 by means of the axle pin 11 as a rigid axle and arranged on the axle pin 11, spaced apart in the he direction bearing elements 15, 16 acting in operation on the bearing elements 15, 16 moments and thus their wear can be kept low.
    Instead of sliding bearing elements, as described in the exemplary embodiment, and rolling bearings could be used, for example in the form of angular contact ball bearings. Various other modifications of the described embodiments are conceivable and possible without departing from the scope of the invention. Thus, for example, another clamping mechanism could be used to hold the immersion molds 7 under clamping of their bottom 7a.
    A holder designed in accordance with the invention may also be designed to hold other types of dip molds, which for example may also be made of plastic. Thus, the dipping form, for example, from the holder have einklemmbare locking lugs on the outside.
