Definitions

  • the invention relates to a device for unrolling and separating material webs, in particular cleaning cloths made of single or multi-layer paper, which essentially consists of a tubular frame, a shaft for receiving the material web roll, and bearings for the shaft.
  • Devices of this type have been in use for a long time, they essentially consist of two U-brackets which are connected to one another in an articulated manner, the U-brackets with their part connecting the legs standing on the floor and the legs of the two U-brackets crossed are.
  • a shaft is usually mounted in this cross, which can be inserted into a roll of material web.
  • the connection between the material web roll and the shaft can take place via inserts or cones engaging in a sleeve of the material web roll, alternatively the sleeve can be designed correspondingly.
  • a support is also mounted on the U-brackets, which also serves as a knife holder, the knife resting on the roller.
  • the relatively large and weighty roles become horizontal stored in the stands, some of which are also equipped with wheels and can thus be operated similar to a hand truck in the operating room.
  • a vertical arrangement of the rollers is not possible with these known stands.
  • the present invention is therefore based on the task of creating a smaller, handy dispenser which can be operated both in a horizontal and in a vertical position and in which the unwanted unrolling of a material web is reliably prevented in both arrangements.
  • a device for unrolling and separating webs of material in particular cleaning cloths made of single or multi-layer paper, which essentially consist of a tubular frame, a shaft for receiving the web of material web, and bearings for the shaft, with the characteristic feature that the tubular frame consists of two U-shaped brackets, the shortened leg of the large U-bracket is rigidly connected to the small U-bracket in the area of the web offset by 90 degrees to the large U-bracket and the large U-bracket in the center area of both Leg bearing for receiving the shaft and the Traverreesses large U-bracket is provided with a pivoted pressure spring loaded by spring force in the direction of the shaft.
  • This construction results in a stand that has three feet.
  • the roller is mounted between the two legs of the large U-bracket and is pressed against by the spring-loaded pressure bracket unintentional unwinding, both in the vertical and in the horizontal position.
  • the horizontal position can be made possible by rotating the stand by 90 degrees and then resting on the shortened leg of the large U-bracket and the two legs of the smaller U-bracket.
  • there is a three-point support which means that the stand as such is always fixed and does not tilt.
  • An advantageous embodiment of the invention provides that holes are made in the legs of the large U-bracket as bearings for the shaft.
  • the thru axle is guided through the holes in the legs and then through the hollow shaft, so that the hollow shaft is supported on the thru axle in a wire-like manner.
  • the material web roll can be mounted directly on the hollow shaft by means of cones and then the thru axle is inserted through the fully assembled unit, so that a quick connection between the holder and the material web roll is ensured.
  • the shaft is provided with lugs, one of which is displaceable in the longitudinal direction against the pressure of a spring.
  • lugs one of which is displaceable in the longitudinal direction against the pressure of a spring.
  • an advantageous embodiment of the invention provides that the tubular frame is provided with through holes in the region of the ends of the long legs of the U-bracket and in the upper region of the short leg.
  • the through holes have a double meaning. On the one hand, they enable direct te fastening, screwing means of the tubular frame to a wall or floor surface so that the Ab - roller stationary device can be brought as; swiveling is then no longer possible, but on the other hand the through holes serve to accommodate rubber knobs that allow the unwinder to move more securely when it is in a vertical position, and on the other hand it prevents scratching of the documents, e.g. a desk top .
  • a further advantageous embodiment of the invention provides that the pressure bracket is arranged on a guide pin extending parallel to the web.
  • An expedient alternative to the one-armed lever is to weld side boundaries, which are advantageously designed with a catch, to the U-bracket and to provide them with a hole through which a bolt can be inserted, which then serves as a guide bolt for the pressure bracket. In this case, too, it is possible to reposition the pressure bracket by pulling out the bolt, so that paper can be pulled off to the left or right.
  • a further expedient embodiment of the invention provides that the pressure bracket consists of a section steel bent into an open T. It is readily possible to design the pressure bracket such that the end of the bracket resting on the material, that is to say the roll, is a flat steel, which can optionally be designed as a knife or tear-off rail. In addition to the fact that such designs usually seem rather bulky, this also results in an unnecessarily high weight of the construction, as well as a larger amount of material is required. Furthermore, there are several processing steps, because the flat iron must be connected to the web or the U-bracket via any connections.
  • profile steel for example in the form of a round bar, but more appropriately in the form of a square bar with an edge length of 3 to 5 mm, there is on the one hand the considerable reduction in weight, and on the other hand this steel can be bent into any shape without any difficulties, so that it can be bent very quickly into an open T, and the two parallel leg ends of this T can also be provided with eyes by bending be around the web of the U-bracket or the guide pin.
  • the pressure spring is arranged between the profile steel ends which form the web of the open T, the profile steel ends of the open T expediently resiliently against at least one fixed lateral on which Guide pin arranged, limit can be pressed with a notch.
  • the arrangement of the pressure spring between the two profile steel ends results in a reduction in space requirement, that is to say that the guide pin extending parallel to the web only has to be relatively short, because of this brevity, the material of this bracket need only have a lower thickness, since it is due to the short lever arm is only slightly loaded.
  • the spring inserted between the profile steel ends not only serves as a pressure spring for the pressure bracket, but at the same time spreads the profile steel ends outwards, as a result of which they are pressed against both a fixed lateral and a releasable lateral boundary.
  • An expedient embodiment of the invention provides that a stabilization is arranged in the foot region of the long leg or in the head region of the short leg of the large U-bracket.
  • the stabilization consists of a flat steel, which is placed around the leg in the form of a clamp and then extends further outwards parallel to the end face of the web of material web, wherein it is provided in the middle of the clamp with a threaded bolt which is inserted into the through hole of the long one Leg of the large U-bracket inserted and can be attached here with a wing nut, for example.
  • the same stabilization is used in the upper area of the short femoral neck, i.e. inserted and screwed if the unwinding device is to be used in the vertical position.
  • a section steel bent to form a rectangle can be used as stabilization, which is advantageously bent analogously.
  • a preferred embodiment of the invention provides that the tubular frame is divided in the area of the bottom of the U-bracket and is connected by a plug connection.
  • the tubular frame is expediently provided with stub axles.
  • the division of the tubular frame enables the entire construction to be carried out from only two parts, i.e. the area of the small U-bracket with a welded-on short leg and the area of the long leg, with both parts interrupted approximately in the middle and connected by a plug connection in the area of the web.
  • there is a considerable space advantage in terms of the space required when packaging the unit i.e. that the packaging is reduced to half the size.
  • Another advantage can be seen in the fact that the guide pin, which is used for receiving and pressing the spring, can be supported on both sides, i.e.
  • the stub axles carry cones, at least one of which is pressed into the sleeve of the web of material web by a compression spring.
  • the 1 and 2 consists of a large U-bracket 2 and a small U-bracket 3, the large U-bracket 2 having two legs 4, 7 of different lengths.
  • the short leg 4 of the large U-bracket 2 is welded to the web 5 of the small U-bracket 3, so that there is a stand that has three feet.
  • bores 8 are arranged which serve to receive a shaft 9.
  • the shaft 9 is as shown in FIGS. 2 and 4, designed as a hollow shaft and equipped with the cones 23.
  • One cone is fixed in position on the shaft 9 by leg tension spring 28, the other either in the same way or by means of a fixed collar 48 on the hollow shaft 9 and both cones 23 engage in the sleeve 25 of the material web roll 26.
  • the hollow shaft 9 is provided with projections 13, 13 ', of which the projection 13' is slidably mounted in the shaft 9 and is acted upon by a spring 14 via collar 14 '.
  • the entire length of the hollow shaft 9 can thus be reduced by pressing in the projection 13 1 , ie that it can be inserted between the legs 4 and 7 of the U- bracket 2 and then, after relieving the spring 14 with the lugs 13, 13 ', fits into the bores 8, a stop lock washer axially defining the arrangement.
  • Fig. 3 is an alternative embodiment of the tubular frame, in which the tubular frame 1 is divided in the area of the crossbeam lo of the large U-bracket 2 and is connected by a plug connection 27.
  • the plug connection 27 consists of a tubular pin 29 which engages in the opposite tube end 3o and is secured against rotation by a cam 32 arranged on a leaf spring 31 and engaging in a recess 33 in the socket of the tube end 3o.
  • the tubular frame 1 is provided with two stub axles 22, on each of which a cone 23 is arranged.
  • the cone 23 In the area of the small U-bracket 3, the cone 23 is arranged in an axially stationary, radially rotatable manner, whereas in the area of the long leg 7 the cone 23 can slide axially on the stub axle 22 and by a compression spring 24, which is located between the cone 23 and the long leg 7 is arranged, is acted upon.
  • the large U-bracket 2 is plugged together, that is to say when the pin 29 is inserted into the pipe end 3o, the cam 32 engages in the recess 33, as a result of which the long leg 7 is mounted so that it cannot rotate and move.
  • the cone 23 presses into the sleeve 25 of the material web roll 26, as a result of which the compression spring 24 is tensioned and the material web roll 26 comes into the correct position.
  • the stabilizing tab 21 is normally made of flat steel with material bends 43 and is provided with a bolt 41 which is guided through the through hole 16 'and here e.g. is attached via wing nut 42 when the tubular frame is arranged in a horizontal position (Fig. l, right). In the case of a vertical arrangement (FIG. 2), the stabilizing tab 21 is fastened by means of the through hole 16 ′′. In this case, 16 rubber buffers 34 are inserted into the bores. Also provided on the stabilizing tab 21 are rubber buffers, through which a firm stand of the trestle is ensured.
  • the stub axle 12 extends through the hollow shaft 9, as can be seen in FIG. 2, and is provided on the opposite side with a wing nut 44 which prevents the stub axle 12 from falling out.
  • F ig. 1 and 2 show details of the pressure bracket 11, ie in particular a fastening in the area of the crossbeam 10 of the large U-bracket 2.
  • the pressure bracket 11 is formed from a square steel and is bent into an open T 17.
  • the profile steel ends 18 are shaped into eyelets 46, between which the leg compression spring 19 is arranged.
  • the leg compression spring 19 is supported against the crossbeam 10 of the large U-bracket 2 and engages a connection 45 between the profile steel ends 18 in order to press the pressure bracket 11 against the web roll 26.
  • the connection 45 is preferably resiliently C-shaped.
  • One leg 19 ' the leg compression spring 19 engages in this connection, while its second leg 19 ′′ is supported on the cross member 10.
  • the profile steel ends 18 are made of a resilient material and press outwards, ie are under a certain pretension Inserted guide pin 15, which extends parallel to the crossbeam lo of the large U-bracket 2 and touch the fixed lateral limit 20 and the mountable stop 36 on one side. Both the limit stop 36 and the fixed lateral limit 20 are each with a catch 35 By pulling up the pressure bracket 11, the profiled steel ends 18 snap into these detents, ie they are first bent against each other when they are pulled up and then spring back outwards as soon as they have overcome the detents 35, so that the pressure bracket 11 is now above the leg spring force above the web of material roll 26 is held in this position it is possible to roll the web of material 26 replace without being hindered by the pressure bracket 11.
  • the stop 36 is secured on the guide pin 15 by a self-locking fuse 37 against displacement by the profile steel ends 18. After removing the self-locking fuse 37, it is possible to remove the stop 36 and then to pull the pressure bracket 11 with the pressure spring 19 arranged in between from the guide pin 15. By rotating the open T 17 together with the pressure spring 19 by 180 degrees, the pressure bracket 11 can be arranged in an arrangement offset by 180 degrees, that is to say on the other side of the material web roll 26 be net, whereupon the stop 36 is then plugged in and the self-locking fuse 37 are placed on the guide pin 15.
