Definitions

  • the invention relates to a device for applying blanks as a face and edge protection for web rolls, in particular web rolls made of pressure-sensitive goods.
  • Pressure-sensitive goods that are wound into rolls are known in a large number.
  • printed and unprinted foils made of plastic and aluminum, as well as paper should be mentioned.
  • the so-called carbonless papers, particularly the carbonless papers are particularly sensitive to pressure. It is of great importance for this material in particular that the end faces and the edges are protected against undesirable loads, such as pressure or impacts.
  • the invention is therefore dealt with below on the basis of the application of round blanks on paper rolls.
  • the object of the invention is therefore to provide a device with which the application of the blanks to material web rolls is simplified, so that even inexperienced persons can do this after a brief introduction Can do work. Another task is to reduce the material required for adhesive tape, to ensure the centric application of the circular blank and, most importantly, to reduce the time required to apply the circular blank.
  • the pin has the same diameter as the inside width of the core sleeve of the roll of material web, this diameter also being identical to the corresponding recess in the round blank.
  • the swivel arm connected to the pin via a joint has a folding mechanism which, by swiveling the swivel arm into the horizontal, folds at least one of the tongues of the round blank, which can thereby be fastened to the web of material web with the adhesive unit.
  • the pin is provided according to an advantageous embodiment of the invention with a clamping eccentric, so that by fixing the eccentric the entire device is fixed in the roll of material and when folding and moving the swivel arm there is no longer any risk that the device will misalign, i.e. H. the pin emerges from the core sleeve of the material web roll.
  • a preferred embodiment of the invention therefore provides that the folding mechanism with the adhesive unit assigned to it is arranged displaceably on the swivel arm by means of a sleeve.
  • the sleeve is preferably equipped with a lock for fixing the position on the swivel arm.
  • the displaceability of the sleeve allows the device to be adapted to the diameter that occurs in each case, with the lock providing a locking possibility, ie ensuring that the diameter which has been set once is not changed while the material web roll is being driven around. This means that the operator of the device no longer has to pay attention to the fact that the folding device is always pressed evenly onto the roll of material web, since this was already set for the entire movement sequence after the hand lever was bent by locking the lock.
  • the sleeve consists essentially of a piece of pipe with this associated handle to be able to move it on the swivel arm.
  • the swivel arm can be designed as a smooth tube, in this case the sleeve is fixed by means of a friction lining pressed against the coupling by means of spring pressure, this spring pressure for adjusting the sleeve on the swivel arm can be released by actuating a relief handle.
  • the folding mechanism can simply be an angled, inclined sheet metal, by means of which the tongues are bent during the circular movement of the swivel arm.
  • the folding mechanism consists of a running profile attached to the holder and a folding cone connected downstream of it.
  • the running profile surrounds the sleeve and, rotatably mounted on it, is arranged between the folding cone and the holding mandrel. Its task is to ensure a constant distance between the circular blank and the swivel arm lying horizontally after being bent, which ensures that the gluing unit is always guided around the web of material at the same height.
  • the folding cone transmits the rotary movement to the folding cone connected downstream of it, which, because it has a larger outer diameter, acts on the tongues of the round blank with a higher peripheral speed.
  • the folding cone is arranged in such a way that the point of the smallest diameter at the level of the tongue feet of the round blank engages, the largest diameter is thus in the area of the outer tongue ends. The edges of the tongues are thus bent by both a pressure and a rotary movement, which considerably simplifies the folding process.
  • An expedient embodiment of the invention provides that the adhesive and cutting device is arranged pivotably on the sleeve. This means that it is arranged in such a way that it can be moved into the gluing and thus pressing position and thus a pressure is exerted on the folded tongues of the round blank.
  • the unit itself essentially consists of a spring-loaded pressure roller, in which a gluing device, expediently a unit for applying a hot pusher, is used in order to achieve the shortest possible setting times.
  • the preferred apparatus solution consists in assigning an adhesive unit, which consists of a trestle for adhesive tape, a pressure roller and a cutter for the adhesive tape.
  • the adhesive tape is meaningfully self-adhesive tape, that is, a tape that does not have to be moistened first and therefore requires a certain setting time, but rather an adhesive tape with a permanently plastic adhesive.
  • the pivotable holder of the gluing unit has the further advantage that when the gluing unit is pivoted away, the cutter is simultaneously brought up to the adhesive tape and cuts through it, so that the adhesive tape is attached and pressed on by pivoting in, while at the same time the cutting is performed when pivoting down , d. H. that the entire connection process is controlled by two movements.
  • the material web roll 1 of FIG. 1 has a customary core sleeve 2 and consists of layers 5 of pressure-sensitive material which is to be protected against pressure on its upper outer cylindrical circumference 3 and end face 4. This is achieved by means of a circular blank 6 with circumferentially arranged and bent tabs 7 which are glued in this position to the device according to the invention.
  • the paper web roll 1 has a radius R which extends from the center of the core sleeve 2 to its circumference 3.
  • the device consists of four assemblies, such as bearing 10, swivel arm 11, folding mechanism 8 for the tabs 7, and adhesive and cutting device 13.
  • the bearing 10 has a pin 14 which is inserted into the core sleeve 2.
  • the pin 14 of the bearing 10 can be fixed in the core sleeve 2 with a clamping device 15.
  • a corrugated clamping eccentric 16 is provided, which is attached eccentrically with eccentricity “e” to a bearing and actuating pin 17.
  • a handle 18 is attached.
  • the pin 14 has in its upper region a support flange 19 which comes to rest on the end face of the paper web roll 1, that is to say at the upper end of the core sleeve 2 on the round blank 6.
  • a swivel arm 11 is articulated in the vertical direction by means of hinge pin 32 via eye 31.
  • the swivel arm 11 is tubular and has a longitudinal slot 28 which extends almost over the entire length of the tubular swivel arm 11. At its other end, the swivel arm 11 has an end stop 33.
  • the folding mechanism 3 On the swivel arm 11, the folding mechanism 3 is slidably and fixably arranged, which essentially consists of the folding cone 12 on the sleeve 36 with the running profile 35; Likewise, the adhesive and cutting device 13 is arranged on the swivel arm 11.
  • the folding cone 12 preferably has a cone angle a of 90 ° and is cup-shaped, i. H. hollow.
  • This running profile 35 has the task, when strapping, to drive the folding cone 12 by means of friction on the circular blank 6, secondly to store the adhesive and cutting device 13 and thirdly for pressing the outer area of the circular blank 6 against the end face 4 of the paper web roll 1 To take care.
  • the extension 34 is penetrated by a sleeve 36, which continues outwards and carries a grip sleeve 37 there.
  • a bracket 40 is also attached, which carries a relief lever 38, rests in the lever bearing 39 and is connected via a receptacle 41 and plunger 42 with the sleeve 36 or the pivot arm 11.
  • the sleeve 36 is arranged to be longitudinally displaceable on the swivel arm 11.
  • the plunger 42 penetrates the longitudinal slot 28 of the swivel arm 11 and an opening 50 in the sleeve 30 and carries a widened head 43 at its inner end.
  • the plunger 42 is loaded by a compression spring 44 which is supported on the outer contour of the sleeve 36 and Relief lever 38 and thus plunger 42 moved outwards, whereby the widened head 43 comes to rest on the inner tube contour 45 of the swivel arm 11.
  • the widened head 43 is pressed against the inner contour 45 in such a way that the sleeve 36 is fixed on the swivel arm 11.
  • the widened head 43 can also have corrugations on the tensioning side.
  • the flaps 7 are folded over, as seen in FIG. 2 from above and in FIG. 3 from below, with the conical surface 48 on the edges 49 of the flaps 7, which were formed by incisions 51 in the round blank 6 (FIG. 2 +3).
  • the handle 37 is intended to be encompassed at the same time in connection with the relief lever 38 and thus the folding cone 12 and the adhesive and cutting device 13 on the radius R of the material web roll 1 to adjust by moving on the swivel arm 11.
  • the folding cone 12 with the extension 2 is freely rotatably mounted on the sleeve 36, and the adhesive and cutting device 13 are fixedly mounted thereon. This determination is made, as can be seen from FIGS. 1, 2 and 3, by a crosshead 60 with angled legs 61 and 62.
  • An eyelet 71 is attached to the arm 64 'and receives the spring end 72 of the tension spring 73, which is attached with its other end 74 to a suspension bolt 75 on the plate 61 of the crosshead 60.
  • the tension spring 73 tries to pull the cutting device 13 on the one hand in the direction of the spring extension of the spring 73, but on the other hand due to the curved design of the slots 69 and 68 - if one looks at FIG. 2 - in the direction of arrow 76 on the outer circumference 3 the roll 1 or the folded flaps 7 of the round blank 6.
  • the guide pin 66 acts as a fulcrum, while the rear end of the arm 64 'with the guide pin 67 - shown in Fig. 2 - makes a left-hand rotation around this guide pin 66, so that the front end 77 of the cutting and gluing device 13 to the left, i.e. . H. is moved in the direction of arrow 76.
  • the adhesive tape guide roller 80 and the pressure roller 81 are pressed firmly onto the circumference 3 of the roller 1 and enclose the adhesive tape 82 to be glued between them.
  • the pressure roller 81 is of stepped design and has two diameter regions 81 'and 81 ", as shown in FIGS. 1 and 6 in particular. This ensures that the adhesive tape 82 both in region 115 of the tabs 7 and below this region, namely is well pressed in the area 116 of the circumference 3 of the roller 1.
  • FIG. 2 When gluing, as shown in FIG. 2, the entire device is guided around the roller via the ball handle 52 in the direction of arrow 120. After this bonding or strapping has been carried out, the adhesive tape 82 is cut off and then the adhesive and cutting device 1 is pivoted out of the working position by means of the pivoting handle 93. This is explained with reference to FIGS. 3, 4 and 5. All three FIGS. 3, 4 and 5 are bottom views below FIG. 1 in order to be able to describe the adhesive and cutting device 13 arranged on the underside of the housing plate 64.
  • the strapping is first completed in the direction of the arrow until the desired number of layers of adhesive tape 82 have been applied (FIG. 3).
  • the adhesive and cutting device 13 is then pivoted outward against the pulling direction of the tension spring 73 by means of the swivel handle 93 (FIG. 5).
  • this takes place first in the direction of the guide slot part 68 'in the direction of the arrow 94 and then, with the aid of the tension spring 73 in the direction of the guide slot 68 "and thus in the direction of the arrow 95.
  • the guide pin 66 then comes at the end the slot area 68 "to the system (Fig. 5).
  • a spring plate 106 can be provided, which together with the housing bolt 105 acts as a leader.
  • Spring plate 106 and tension spring 99 are attached to a shoulder 107 and thus to plate 64. Due to its own weight during handling, as will be described later, the lever 102 together with the adhesive tape guide roller 80 falls back into its original position. Thanks to the tension spring 99, the nose 101 again engages behind the lever 102, as a result of which the pressure roller 81 comes back into the functional position for the gluing.
  • the roll of adhesive tape is designated 110 and is attached to a mandrel 111 of the eye 112 of the housing plate 64 in an easily replaceable manner.
  • FIG. 6 shows the round 6 that has been glued on completely. It completely covers the edge region to be protected and the end face 4 of the roll 1.
  • the cutouts 51, which form the tabs 7, are somewhat wide and exaggerated here. In fact, they do not interfere in the edge area, since the blank material is relatively thick is executed.
  • the areas 115 and 116 of the adhesive bond can be the same size or also have different widths, depending on how high the degree of adhesion of the adhesive tape 82 to the different materials is.
  • the roll 1, Fig. 7, has a continuous central opening, which is equipped with a core sleeve 2 made of cardboard.
  • a round blank 5 is now placed on the end face 4 of the roll 1 so that its central opening coincides with the opening of the core sleeve 2 (FIG. 8).
  • the device, FIG. 2, is now put on by inserting the pin 14 into the core sleeve 2.
  • the pin 14 is then clamped to the core sleeve 2 via the handle 18.
  • the device is now moved from the vertical position into a horizontal position.
  • the release lever 38 is operated unlocking and with the handle sleeve 37, the entire device on the swivel arm 11 is shifted towards the center of the roller 1, until the flat surface 47 of the folding cone 12 one or more flaps 7 already folded between them Scope 3 of the roll 1 is jammed. So that the radius of the roller R is set and after releasing the release lever 38, the clamping and setting remains constant. With this setting you can now strap as many rolls of 1 of the same diameter.
  • the gluing device 13 is then moved into the action position via the swivel handle 93, in the opposite direction as described under FIG. H. against the direction of arrow 95.
  • the adhesive tape thus comes into the adhesive position.
  • the adhesive device 13 is pivoted out into the non-working position, as has already been described under FIG. 5.
  • the cutting device is actuated by simultaneously turning the lever 98, as described in FIG. 4, and the adhesive tape 82 is cut off.
