Definitions

  • the invention relates to an abrasive belt storage device in which at least one belt roll formed by a wound abrasive belt and having a central through opening has at least one bearing insert in its through opening, which is provided with a rotary bearing surface approximately coaxial with the roll axis for rotatably mounting the belt roll on a support bearing.
  • Such abrasive belts stored in roll form can be rotatably supported and kept ready for pulling off the abrasive belt in that a rod, for example a suspended rod, is inserted through the passage opening of the belt roll, which, if necessary, rotatably supports the belt roll over an inner peripheral surface of the respective bearing insert.
  • a rod for example a suspended rod
  • the bearing rod has a relatively large bearing play compared to the inner circumferential surface forming the pivot bearing surface, so that on the one hand a rather imprecise, oscillating mounting of the tape reel ben is and on the other hand, the sliding friction of the rotary bearing is so low that the tape reel after completion of the tensile load of the end of the tape when pulling a section of abrasive tape to be cut still runs by a relatively large angle of rotation, which leads to an unwanted unwinding of the tape reel.
  • the invention has for its object to design an abrasive belt storage of the type mentioned so that an exact and well braked storage of the tape roll is possible in a simple manner.
  • the design of the pivot bearing surface according to the invention ensures a small space requirement of the bearing inserts which projects beyond the outer limits of the abrasive belt, so that the belt reel is only insignificantly widened by these bearing inserts.
  • the abrasive storage additionally has a support bearing adapted to the band reel or the bearing inserts for easily removable or insertable reception of the band reel.
  • This support bearing can be designed in a simple manner according to the invention in such a way that adjacent tape rolls do not touch each other when rotating and thus do not take them along in the unwinding direction, without requiring a significant additional space requirement.
  • This support bearing expediently has bearing shells for receiving the pivot bearing surfaces, the radius of the bearing shells being able to be adapted to the diameter of the pivot bearing surfaces in such a way that the desired braking effect occurs when the bearing is exact.
  • the support bearing can be provided in a simple manner for the reception of two or more, preferably coaxially adjacent to each other with a horizontal axis tape rolls, so that abrasive tape of different grain size can be kept next to each other.
  • means can be provided for the simple cutting off of the part of the abrasive belt which is in each case pulled off a roll of tape, this separating device being expediently arranged in such a way that it works essentially equally well with each roll diameter.
  • Each bearing insert.6 has one as a sleeve-shaped rotation body-shaped, to its inner end slightly tapered core part 7 with its outer diameter much smaller axial extent, which can be provided with bumps, for example with axial rib-like projections, for better securing against the inner surface of the through opening 4 on the outer circumference.
  • two ring bundles 8, 9 which are spaced apart and project radially outward by as small a dimension as possible, which between them delimit an approximately rectangular or square ring groove with a width in the millimeter range.
  • the inner collar 8 serves as a stop for the axial alignment of the bearing insert 6 with respect to the associated end face 5 of the tape roll 2; this stop can also be formed by individual projections distributed over the circumference or can be omitted entirely, so that the bearing insert 6 is aligned axially with respect to the tape roll 2 only by more or less deep insertion into the through opening 4.
  • the bearing insert Coaxially in the cup-shaped outer sleeve, but provided with openings in the bottom, the bearing insert has a cylindrical hub sleeve 11 supported by radial ribs, through which a support bearing in the form of a rod or the like can be inserted.
  • the tape roll 2 can with the pivot bearing surface 10 or with the outer circumferential surface of at least one annular collar 8 or 9 in recessed cavities of two lateral bearings, indicated by dash-dotted lines in FIG.
  • the bearing cheeks 13 provided as end-side bearing supports are expediently arranged in the form of vertical partition walls at the same intervals, freely protruding from a support or bracket, which can be formed by a plate-shaped rear wall 15 made of sheet metal and offset angle flanges on both sides as fastening members 16 Attachment to a wall, on two rear supports of a shelving system or the like.
  • a support or bracket which can be formed by a plate-shaped rear wall 15 made of sheet metal and offset angle flanges on both sides as fastening members 16 Attachment to a wall, on two rear supports of a shelving system or the like.
  • five bearing cheeks 13 are provided for accommodating four tape rolls, the two outermost of which lie in the region of the side boundaries of the support bearing 3 formed by the fastening members 16.
  • all bearing cheeks 13 are connected to one another via continuous profiled bars, so that a self-supporting frame construction of high strength results.
  • At least each of the bearing cheeks lying between the outermost bearing cheeks 13 has on its upper side two bearing shells 17 which are aligned with one another and lie directly next to one another and whose distance from the rear wall 15 is greater than from the front of the supporting bearing.
  • the distance between the two bearing shells 17 of a bearing cheek 13 is only slightly larger than twice the thickness an annular collar 9 of the bearing inserts 6, so that adjacent bearing inserts 6 of two adjacent tape rolls 2 with their mutually facing end faces can be very close to one another in a space-saving manner.
  • all bearing cheeks 13 are of the same design.
  • Each bearing cheek 13 is formed by two parallel, mirror-symmetrical walls 18 consisting of sheet metal plates, the distance from one another being equal to the distance between their bearing shells 17. These walls 18 are offset or cranked between the bearing shells 17 and the rear wall 15 at their upper edges and in the region of an upper, inclined part of the front edge of the bearing cheek 13 lying in front of the bearing shells 17 and with these cranked edge strips 19, for example by spot welding, attached to each other. Above their horizontal lower edges, the walls 18 can have inwardly projecting, for example knob-shaped, spacing projections 20 with which they abut one another and which can also be fastened to one another by spot welding.
  • each bearing cheek 13 forms a hollow chamber component which is open in the region of the bearing shells 17 and in the region of its underside in accordance with the distance between the walls 18 and is of high strength and low weight.
  • Both walls 18 of the central bearing cheeks 13 and the inner walls 18 of the two outermost bearing cheeks 13 form outwardly angled fastening legs 21 which extend almost over their entire height and with which the bearing cheeks 13 are fastened to the rear wall 15 by spot welding or the like.
  • the outer walls 18 of the two outer bearing cheeks 13 are continued over their rear ends in their plane to the rear and at the remote fastening member 16 fixed by welding or the like.
  • Each bearing shell 17 forms a partially circular, in particular at most semicircularly limited, concave running and braking surface 22 for the engagement of the pivot bearing surface 10 of the associated bearing insert 6, the width of the pivot bearing surface 6 being adapted to the sheet thickness in the area of the respective bearing surface 22 such that it engages in them with relatively little axial play.
  • the radius of the tread 22, which can also be formed by individual, spaced apart projections, is practically equal to half the diameter of the pivot bearing surface 10, so that uniform contact with the pivot bearing surface 10 is ensured over the circumference of the tread 22.
  • each tread 22 merges tangentially into a vertically upward adjoining edge 23 which adjoins the associated edge strip 19 and extends approximately to a height above the lowest point of the tread 22, which is the same as its diameter.
  • the boundary of the tread 22 lying towards the front ends approximately at the level of its central axis 12.
  • the profile bars connecting the bearing cheeks 13 on the front side at the bottom edges are designed as a separating device 24 for the running tape ends 14 of the tape rolls 2, two angled legs projecting forward one across the width of the support bearing 3
  • the lower longitudinal recess of the take-off slot 25, which is set back from the upper limit, is serrated or serrated to form a tear-off edge 27, so that the band end 14 can be cleanly separated by pressure downwards against the tear-off edge 27 and can thus be detached from the tape roll 2.
  • the fastening legs 28 corresponding fastening legs 28 carry the profile bars 29, 30.
  • One length measuring device 26 is provided in the area of the bearing cheeks adjacent to the outermost bearing cheeks 13, that is to say in the area of every second bearing cheek, so that the respective length measuring device 26 can be used for two adjacent belt rolls 2.
  • the respective length measuring device 26 has a measuring rod 31 lying approximately at right angles to the rear wall 15 between the associated walls 18 of the support cheek 13, which is slidably mounted in its longitudinal direction in a guide bracket 32 serving as a sliding bearing on the front of the support cheek 13.
  • the guide bracket 32 is fastened at the protruding angle of the lower profile rod 30, the upright leg of which has a further slide opening for the measuring rod 31, which is opposite the sliding opening in the guide bracket 32 at a small distance, in such a way that, due to its bearing play in the extended state, it also has transverse movements with respect to its direction of displacement execute and can be easily held together with the tape end 14.
  • the rear end of the measuring rod 31 formed by a wire section is angled to form a stop 33. This stop 33 serves by abutment on the rear wall 15 both to limit the stop of the inserted position and by abutment on the profile bar 30 to limit the stop of the extended position.
  • the front end of the measuring rod 31 projects so far freely over the front side of the guide bracket 32 that it can be gripped comfortably for pulling out.
  • the measuring rod 31 projects beyond the tear-off edge 27 by the amount which corresponds to the length of an abrasive belt section as is usually required for use on sliders or orbital sanders.
  • the space between adjacent bearing cheeks 13 is freely accessible from below, the running end of the tape 14 of the respective tape roll 2 can be easily gripped from below and pushed through the trigger slot 25.
