Definitions

  • the invention relates to a towel dispenser according to the preamble of claim 1.
  • a towel dispenser with a height-compensating receptacle for the towel roll with fresh towel is from the document US 6,267,460 B1 GAIDE ET AL. known.
  • towel provided with fresh towel is unrolled from the towel roll, so that the diameter of the towel roll with fresh towel decreases, while the diameter of the dirty towel roll increases as the used towel is drawn in.
  • the receptacle with the towel roll containing the fresh towel is moved upwards in the vertical direction so that the dirty towel roll arranged below this receptacle receives additional space when its diameter increases.
  • the disadvantage of this known towel dispenser is that the towel roll, which becomes larger in diameter when the towel dispenser is used, takes up more and more space against the dispensing opening for the towel made available to the user and thus requires a relatively large overall height of the towel dispenser.
  • the invention aims to remedy this.
  • the invention is based on the object of providing a towel dispenser which is compact and has a minimal overall height.
  • the invention solves the problem with a towel dispenser which has the features of claim 1.
  • the advantage achieved by the invention is essentially to be seen in the fact that, thanks to the towel dispenser according to the invention, due to the height-adjustable dirty cloth roller, the dirty cloth roll, which is becoming larger in diameter, is moved upwards against the fresh cloth roll, which is decreasing in diameter and is also moving upward, so that a minimum Volume of the towel dispenser is achievable.
  • the receiving device is designed as a rocker, which is attached to the support frame so that it can pivot about a first axis of rotation in the vertical direction
  • the cleaning cloth roller is rotatably mounted on a pivot lever about a second axis of rotation, which is attached to the support frame so that it can pivot about a pivot axis in the vertical direction.
  • the means for lifting comprise a gear, by means of which the pivoting movements of the rocker and the pivoting lever are rotatably coupled to one another.
  • a sufficient contact pressure is maintained between the drive roller mounted on the rocker and the dirty cloth roller mounted on the pivot lever via the dirty cloth roller, regardless of the diameter, ie regardless of the weight of the fresh cloth roll.
  • the rotative frictional connection between the drive roller and the dirty cloth roller is maintained in every position of the rocker and / or dirty cloth roller.
  • the spring motor In conventional systems with a spring motor, the spring motor generally always wants to rotate (pull-in). However, if no cloth has been issued, no cloth can be drawn in. The spring motor is held still due to the prevailing friction.
  • the contact pressure on the feed roller is high, the friction is high. If the roll of fresh towels is empty, the contact pressure is low and the system can slip, which can cause the spring motor to discharge. This can result in a malfunctioning system.
  • sufficient contact pressure is ensured by the Transmission always given. Regardless of how many portions of fresh towel are in the fabric bowl or the dirty towel on the winding axis. The entire weight of the roll of cloth is always pulled down. The force is introduced accordingly through the gear. In this way, the unloading of the spring motor can be minimized or prevented in all positions.
  • the means for lifting comprise a bracket which is rotatably attached to the support frame about the first axis of rotation and is movably connected to the dirty cloth roller.
  • a gearwheel is rotatably attached to the bracket, which gear engages in a first gearwheel segment attached to the rocker and in a second gearwheel segment attached to the support frame.
  • the means for lifting comprise the pivot lever attached to the support frame so as to be pivotable about the pivot axis in the vertical direction and a support fixed relative to the support frame, the dirty cloth roll rolled up on the dirty cloth roller resting on this support.
  • the vertical movement of the dirty cloth roll together with the drive roll and the receiving device for the clean cloth roll can take place via a support for the dirty cloth roll (e.g. one or two rolls) which is fixed to the support frame on the underside of the dirty cloth roll.
  • the drive device comprises a spring-loaded drive.
  • a first guide roller for guiding the fresh towel is attached to the receiving device, whereby by means of the first The spring-loaded drive can be pre-tensioned when unwinding fresh towels from the fresh towel roll.
  • the drive device is arranged on the receiving device for the fresh towel roll.
  • the towel dispenser comprises a time delay device which is activated when the fresh towel is unwound and activates the drive device for driving the drive roller after a specified period of time has elapsed.
  • FIG. 1 shows a longitudinal section through an embodiment of the towel dispenser according to the invention without a hood
  • FIG. 2 shows a side view from the outside of the embodiment of the towel dispenser according to the invention shown in FIG. 1;
  • FIG. 3 shows a longitudinal section through the embodiment of the towel dispenser according to the invention shown in FIG. 1;
  • FIG. 4 shows a perspective view of the receptacle for the fresh towel roll of the embodiment of the towel dispenser according to the invention shown in FIG. 1;
