Definitions

  • the invention relates to a device for unrolling material webs, in particular one
  • Dispensing device for paper towels from a roll which essentially consists of two side walls with bearing stubs arranged thereon for receiving a material web wound up on a roll sleeve to form a roll.
  • Towel dispensers that work from Rolle are in great use, as are cleaning towel dispensers.
  • the first type also includes the rolls in which a shaft, which may be part of the dispenser, must be inserted before being inserted into the dispenser.
  • a shaft which may be part of the dispenser
  • the bearing stumps are arranged on side parts that may. are springy or must be put together. Another possibility is described in US Pat. No. 3,088,686.
  • a side part is guided in the base plate and pulled inwards by spring force, ie that in order to replace the roller, one side part has to be pulled outwards against the spring force and the roller can then be used.
  • a device for unrolling material webs in particular an output device for paper towels from a roll, which essentially consists of two side walls with bearing stubs arranged thereon for receiving a material web wound on a roll sleeve to form a roll
  • this is achieved in that the bearing stubs on a the side walls of an output device passing through folding bearings are arranged and are held in the working position by spring force.
  • both stumps can be folded to the side, the role can either from the right or from the left, d. H. be used with the right or left hand by first placing it on a bearing stump, pressing it outwards, whereupon this process is repeated on the opposite side, while the first bearing step already engages in the roller sleeve.
  • the supply roll like the dispensing roll, must be used in such a way that the paper web is unwound counterclockwise when looking at the left side wall of the dispenser. The location of the start of the web The supply roll is completely irrelevant, since the supply roll, when the dispensing roll has been unwound, is automatically rotated when the last lengths of web are pulled off the dispensing roll and thus the beginning of the web of the supply roll is brought together with the web end of the dispensing roll.
  • a particularly preferred embodiment of the invention provides that the bearing stumps are provided with a bevel which reduces the contact area between the winding tube and the bearing stump in the direction of the folding pin.
  • the bearing stump when viewed from the front, has the shape of an essentially right-angled triangle, in which the winding tube lies on the horizontal side of the triangle.
  • a tip of the triangle is directed towards the folding bearing, which, based on the working direction, that is, the direction in which the roll rests and in which the paper is drawn off, is arranged at the bottom, so that a pressure is exerted when a paper web is pulled off the roll is exercised on the horizontal triangle side, which additionally leads to the fact that the spring, which presses the bearing and holds it in position, is supported.
  • folding bearings are connected to the side walls by means of folding bolts and eye bearings, or that the folding bearings are pressed against the side walls by a pressure spring.

  • FIG. 9 shows an alternative solution to FIG. 8.
  • a portioning roller (1) which is provided with a friction lining (2), is arranged in the lower region of the sheet dispenser.
  • the end faces of the portioning roller (1) have a spiral guide (3), in each of which a nose (5) of a slide (6) engages.
  • the slider (6) engages with its slot (7) Shaft (8) of the portioning roller (1). If the portioning roller (1) is moved clockwise by pulling the paper web (39), the nose (5) slides in the spiral guide (3) and thereby moves the slide (6).
  • the slider (6) which is knee-shaped in its lower area, has a joint (11) at the end opposite the nose (5), which connects it to the knife (12) and the knife lever (14)
  • Bearing blocks (81) of the portioning roller (1) is articulated and engages the recess (65) in the bearing blocks (81).
  • the rear portion of the knife (12) which is designed as a toothed knife blade, projects beyond the joint (11) and there has knife bolts (45) which engage in the fork (9) of the release anchor (10).
  • the release anchor (10) which is articulated to the slide (6) via a stud bolt (44), has a stopper surface (17) on the outside of an anchor surface and the inner stopper surface (82) on the inside of the other anchor surface.
  • the stops (18) arranged on their end faces (43) abut against the stop surfaces (17) of the release anchors (10), which interact with both end faces (43).
  • a length of web has been unwound, at the same time the slide (6) has moved to its outermost position, as a result of which the knife (12) has been brought outwards and thus into the area of the removed paper web (39).
  • the knife (12) is now in engagement with the paper web (39) Further pulling cuts the paper web (39) and releases the web section (50), at the same time the knife is moved against the spring force direction of the knife spring (13) up to the stop against a backstop (42), causing the release armature (10) to move over the in the fork (9) of the release armature (10) engaging knife bolt (45) is rotated around the stud bolt (44) so that the stopper surface (17) lifts off the stop (18).
  • the knife (12) is locked in this position on the backstop (42) and is only pulled back by the knife spring (13) when the web section (50) has been cut off, that is to say no more pull is exerted on the knife (12).
  • a spring-operated feed to be explained later rotates the portioning roller (1) clockwise a few degrees until the stop (18) abuts the inner stop surface (82) and locks the portioning roller (1) a second time, thereby creating a new piece the paper web (39) is guided out of the dispenser so that it can be gripped by hand.
  • the nose (5) is guided in the spiral guide beyond the shoulder (4) and the knife (12) is released from the stopper (42) by the knife spring (13).
  • the nose (5) can thus be returned to its starting position by the return spring (15) which acts on the leg (16) of the knife lever (14), so that the knife (12) is retracted.
  • the paper web (39) is located on a delivery roller (38) which is arranged in the upper region of the dispenser and rests on bearing stumps (26).
  • the bearing stump (26) consists of a downward bevelled pipe section and is an integral part of a folding bearing (24) which is pressed by means of a pressure spring (25) through the right or left inner wall (56), (57) of the dispenser and can be folded in and out with the folding pin (23) connected is.
  • the folding pin (23) is received by eye bearings (66) which are arranged on the inner walls (56, 57).
  • the space between the inner walls (56) and (57) corresponds to the width of the discharge roller (38). If the dispensing roller (38) is used, this is done from below, i.e. along the slope (47) of the bearing stumps (26), which fold outwards until the winding tube (76) of the dispensing roller (38) is reached, i.e. up to the time when the pressure spring (25) press the bearing stumps (26) into the winding tube (76) of the dispensing roller (38).
  • the diameter of the delivery roller (38) is limited by a limiter (51) arranged in the rear wall (53) in such a way that only delivery rollers (38) with a defined maximum diameter can be used.
  • a button (31) rests on the delivery roller (38), which is mounted in a bearing pin (32) and held in the support position by means of a button spring (33).
  • a hinge pin (30) connects the handrail (29) to the button (31) and is guided in a handrail guide (49). The lower area engages with the catch (28) of a swivel plate (27), which can be moved around the swivel pin (22) and carries a folding bearing (24).
  • the supply roll (40) rests on both sides in folding bearings (24). However, one of these folding bearings (24) is located on the swivel plate (27), i.e. that the supply roller is offset on one side by the swivel plate spring (27) against the toothed roller (21), which is mounted in the toothed roller block (46).
  • the brake (20) is no longer in engagement with the circumference of the supply roll (40) so that it can rotate freely.
  • the sprocket (21) presses the.
  • the fill level lever (34) which is held in this position by the fill level spring (36), lies on the supply roll (40) with a fill level sensor (37).
  • the lid (54) of the dispenser has a fill level window (35) through which the scale (52) of the fill level lever (34) can be seen; the fill of the dispenser is thus visible from the outside.
  • the scale (52) is designed so that a warning already appears when 2/3 of the supply roll has been used up. If the container is refilled in this state, the now partially unwound supply roll (40) is exchanged for the empty winding tube (76) of the dispensing roll (38) and a new supply roll (40) is inserted into the dispenser. In a departure from FIGS. 2 to 8, the release mechanism for the supply roll (40) is constructed differently in FIGS. 1 and 9.
  • the delivery roller is scanned by a slide (69) resting on the delivery roller (38), which forms an integral part with a flat profile (71), is rotatable about the bolt (70) and a pin (72) on the slide (69) opposite end.
  • This pin (72) engages in the control fork (73) of an L-profile (74) which is connected to the right inner wall (57) of the dispenser via a bearing pin (75).
  • the front area of the L-profile (74) has a hook stop (77) which engages behind a projection (78) of the folding bearing (24) arranged on the swivel plate (27).
  • the toothed roller (21) sits on the right side of the cover (54) in a toothed roller block (46) which is an integral part of the cover (54).
  • the lid is mounted in lid bearings (58) which are located in the right and left inner walls (57), (56). It has in its upper region in the vicinity of the ⁇ back wall (53) has a retaining slot (67) which engages in the one arranged on the rear wall of resilient hooks (68).
  • the portioning roller (1) is arranged on bearing blocks (81), which is folded forward when the cover (54) is folded down, so that the paper web (39) can be conveniently changed between the pressure rollers (19 ) and the portioning roller (1) can be passed.
  • the shaft (8) of the portioning roller (1) extends through one of the bearing blocks (81) and carries at its outer end a curved segment (63) which has a transport surface (64).
  • the curve segment (63) stands in engagement with the sliding surface (60) of the transport lever (59), which is pressed against the cam segment (63) by the transport spring (61). If the paper web (39) is pulled off and the portioning roller (1) is rotated, the cam segment (63) is rotated at the same time, ie the sliding surface (60), which is in the idle state of the portioning roller (1) on the transport surface (64), slides along the circumference of the curve segment (63), moves the transport lever (59) downwards and in the process tensions the transport spring (61).
  • the portioning roller (1) is locked in that the stopper surface (17) of the release armature (10) abuts the stop (18) of the portioning roller (1) .
