Definitions

  • the invention relates to a device for receiving rotatingly driven bobbins (wound material web) with a hub on which the bobbin is supported with a central opening, and with a releasable securing means for temporarily fixing the bobbin on the hub.
  • Bobs of packaging material are required in connection with packaging machines.
  • the bobbins must be stored in such a way that the web of packaging material can be continuously pulled off while rotating them. It is desirable that the bobbin itself does not rotate on the hub, but that it rotates together with the bobbin.
  • the union nut as a tensioning or holding element is relatively cumbersome to use. This is particularly unfavorable if - as with packaging machines - the bobbins often have to be replaced due to the high material consumption.
  • the pressure disc resting on the bobbin prevents the material web from running off the bobbin when the area covered by the pressure disc is moved.
  • the invention is based on the object of proposing a reel holder or receptacle which is simple and reliable in construction and handling and which ensures trouble-free fixing of the reel on the hub.
  • the bobbin holder according to the invention is characterized in that at least one clamping claw can be pressed resiliently against an inner region of the bobbin, in particular against a sleeve-shaped (cardboard) core, and can be moved from the holding position by an actuator against the elastic pressure.
  • holding members are pressed against the inner region, in particular exclusively against the (cardboard) core, specifically preferably by (compression) springs.
  • the one-sided clamping claws press the bobbin or the sleeve-shaped core against an abutment disc and thereby fix the bobbin.
  • the clamping claws are moved back from the clamping position in such a way that they lie within the cross-sectional area of the hub.
  • the bobbin change can be carried out without hindrance.
  • the clamping claws are moved into the retracted position by pressure medium - against the load on the springs.
  • the pressure medium in particular compressed air, acts on an actuator common to several, in particular three, clamping claws.
  • the holding or tensioning element for the bobbin that is to say in particular clamping claws, is designed in such a way that this or the latter is partially form-fitting as a result of the axially acting pressure penetrate the (cardboard) core.
  • clamping claws they are designed with sharpened edges, which penetrate into the notches of the core while deforming the material.
  • the bobbin holder shown as a preferred embodiment in the drawings is arranged on a machine frame 10, for example a packaging machine.
  • a hub 11 is rotatable - via two spaced ball bearings 12 and 13 - on a protruding from the machine frame 10 and supported in this support pin 14.
  • a bobbin 15 is accommodated on the hub 11. This sits with a sleeve-shaped (cardboard) core 16 on a cylindrical support part 17 of the hub 11. This is delimited on the side facing the machine frame 10 by an abutment disk 18 against which the bobbin 15 is pressed in the working position.
  • the end of the hub 11 or the supporting part 17 opposite the abutment disk 18 is free of projections etc. and is designed with a bevel 19 on the edge to make it easier to slide the bobbin 15 on.
  • the bobbin 15 In the working position (FIGS. 1 and 4), the bobbin 15 is fixed on the supporting part 17 by movable holding members, namely pivotally mounted clamping claws 20.
  • clamping claws 20 In the present exemplary embodiment, as can be seen in FIG. 2, three such clamping claws 20 are at equal angular distances from one another distributed attached to the hub 11.
  • the clamping claws 20 are each designed as pivotable (two-armed) levers and are mounted in such a way that they can be pivoted between a retracted position according to FIG. 3 that allows the bobbins 15 to be changed and a clamping or holding position according to FIG. 4. In the retracted position (FIG. 3), the clamping claws 20 have completely disappeared within the cross section of the hub 11 or of the support part 17.
  • the clamping claws 20 are directed approximately radially.
  • One of the bobbin 15 or the core 16 facing clamping edge 21 of the clamping claws 20 is inclined, that is at an acute angle to the radial.
  • the clamping edge 21 is sharpened wedge-shaped or knife-like. Due to the clamping force exerted on the clamping claws 20, the clamping edge 21 is pressed into the (cardboard) core 16 with corresponding deformation, forming a corresponding notch. The core 16 is thereby positively held by the clamping claws 20 and fixed against relative rotations on the supporting part 17.
  • the clamping claws 20 are mounted inside the hub 11 or the cylindrical support part 17.
  • axially directed slots 22 are arranged in the support part 17 in the area of the clamping claws 20 for the passage thereof.
  • the end of the lever-shaped clamping claws 20 opposite the tensioning end or the clamping edges 21 is movably mounted on the support part 17, namely in a radial, slot-shaped recess 23 of an inner cylinder 24 of the support part 17.
  • a guide pin 25 attached to this end of the clamping claw 20 slides in the slot-shaped Recess 23.
  • the clamping claw 20 is rotatably or pivotably mounted on a setting or actuating member for the clamping claws 20 with a bearing pin 26. It is a sliding sleeve 27 which is axially displaceably mounted in an annular space 28 of the support member 17.
  • the annular space 28 is inside of the inner cylinder 24 and outside bounded by an outer cylinder 29.
  • the bearing pin 26 is located within a longitudinal slot 30 of the sliding sleeve 27 through which the clamping claw 20 also passes. A displacement of the sliding sleeve 27 in the axial direction causes the clamping claws 20 to pivot in the sense described, the guide pin 25 sliding in the recess 23 in the radial direction.
  • the sliding sleeve 27 as an actuator for the clamping claws 20 is spring-loaded in the direction of the clamping position (Fig.4).
  • three (helical compression) springs are distributed in the circumferential direction at equal angular distances.
  • the springs 31 partially enter longitudinal bores 32 (blind bores) of the sliding sleeve 27.
  • the other end of the springs 31 is supported on a radial end wall 33 of the hub 11.
  • Corresponding holding bores 34 are arranged in this for guiding the springs 31.
  • the sliding sleeve 27 for actuating the clamping claws 20 is adjusted by a pressure medium, namely compressed air.
  • the sliding sleeve 27 acted upon directly by compressed air acts as an annular cylinder.
  • An end face 35 remote from the springs 31 is acted upon by compressed air within the annular space 28, which acts as a correspondingly designed cylinder chamber, and is sealed off from the outside by seals 55.
  • a distributor ring 36 adjoining the annular space 28 is formed on the side remote from the sliding sleeve 27. This is connected on the one hand to the annular space 28 and on the other hand to an intermediate chamber 37 via radial channels 38.
  • the intermediate chamber 36 in the inner cylinder 24 is connected to the compressed air supply.
  • the sliding sleeve 27 is pressurized with compressed air in the sense described and thereby displaced in the axial direction towards the free end of the hub 11.
  • the clamping claws 20 are pivoted (clockwise) against the springs 31 compressed in the process.
  • the compressed air system is vented to clamp or fix a bobbin 15 on the supporting part 17.
  • the sliding sleeve 27 returns to the position shown in FIG. 4 with the corresponding adjustment of the clamping claws 20.
  • the intermediate chamber 37 has a dimension in the axial direction that allows certain axial displacements of the hub 11 on the support pin 14 - as a result of dimensional tolerances - without the branch coming out of the area of the intermediate chamber 37.
  • the compressed air line 39 is connected in the area of the machine frame 10 through a transverse channel 40 to an annular distributor chamber 41. This is laterally limited by seals 42.
  • a radial connection bore 43 connects the distribution chamber 41 to a main line 44, which leads to a compressed air source.
  • a (manually operated) shut-off device 45 is provided.
  • the part of the trunnion 14 lying away from the hub 11 is supported in a closed bearing body 46 of the machine frame 10.
  • the distribution chamber 41 is also formed in this.
  • the cylindrical support pin 14 is secured against rotation by a radial locking pin 47 in a groove 48 of the bearing body 46.
  • the present bobbin holder enables the hub 11 to be adjusted such that the bobbin 15 or the running material web can be adjusted to an exact relative position.
  • the support pin 14 is arranged axially displaceably in the bearing body 46. At the end remote from the hub 11, the support pin 14 is connected to a push rod 49. Its free end comes out of the bearing body 46 and is connected to an actuator. In the present case, it is a worm wheel 50 arranged on the push rod 49, which is rotatably driven by a worm 51 in order to transmit adjusting movements to the support pin 14.
  • the push rod 49 is designed as a spindle 53 with an area entering the support pin 14.
  • the external thread of the same is in engagement with an internal thread of a longitudinal bore 54 in the support pin 14. Accordingly, by rotating the push rod 49, the support pin 14 is adjusted very delicately, without the push rod 49 itself executing axial movements. Rather, it is secured against this by a collar 52 arranged on the push rod 49, which is positively mounted within the bearing body 46.
  • the special design of the clamping claws 20 for the form-fitting fixing of the core 16 and the axially directed adjustability of the support pin 14 (setting gear) can also be used independently of one another or with a reel holder designed and operated in a different way.
