Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper towel dispenser in which paper is arranged in a roll in a housing and is discharged from below through an outlet when necessary.

[0002]

2. Description of the Related Art Paper towel presenters in which paper is wound on a paper roll are already known.

The feeding drive device is adapted to manually or automatically pull out the paper and, after reaching a predetermined withdrawal length, actuate a restraint device for preventing further withdrawal and simultaneously actuate the cutting device. There is.

It is also known to rotate a paper roll through a latch device to pull out the paper, unwind it to a predetermined length, then lock the latch device, and similarly actuate the cutting device. .

Both of these types of paper towel dispensers have the disadvantage that only a very limited number of paper towels can be taken out. With this method, after the paper is completely pulled out from the paper roll, no more paper can be taken out from the paper towel submitter.
Not useful for places where heavy consumption and large quantities of paper towels are needed. This is uncomfortable and causes difficulties in providing such a paper towel dispenser with a roll of paper.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to allow such a paper towel dispenser to have an increased capacity for withdrawing paper towels in substantially the same required space.

[0007]

According to the invention, the object is, in a paper towel dispenser of the type mentioned at the beginning, that there are at least two or more paper rolls in the housing, each paper roll being present. Can be driven separately, both webs from each paper roll meeting just below the outlet of the machine, and one or the other web of webs taken out alternately from the machine.

An advantage of the present invention is that after one strip has been exhausted from the device, a second strip is automatically withdrawn from the device and is ready to be subsequently withdrawn.

This doubles the capacity of such equipment. For example, when two rolls of paper are arranged, the capacity of the paper towel presenter is doubled. It should be noted that it is within the scope of the present invention to increase the capacity of the device by an arbitrary number, that is, two or more paper rolls. However, for simplicity in the following description, doubling the capacity with two paper rolls will be described.

In the present invention, after the drawing of the paper from one roll is completed, the paper is automatically transferred to another roll,
Most of this paper roll can also be consumed, and the first paper roll can be taken out by the time the second paper roll is completely consumed.
You have enough time to replace it with a new roll of paper.

The inspection interval for such a paper towel dispenser is therefore very long, since the empty paper roll is replaced during the consumption time of the second paper roll. Thus, the paper towel dispenser is completely empty and does not have to be refilled at only one given time, there is sufficient time to fill the paper towel dispenser.

In a preferred embodiment of the invention, both paper rolls have separate rotary drives, which are electronically controlled. In this case, a light barrier consisting of a roll transmitter and a receiver is arranged on the strip of paper from the first roll of paper, which detects the end of the first strip of paper and a rotary drive for the second strip of paper. Is advantageous.

Similarly, it is proposed that a light barrier is arranged in the path of the second web, which detects that the second web has been used up and switches to the rotary drive for the first web. To do.

Various methods are conceivable for the rotary drive device for both paper rolls.

In a first advantageous embodiment, it is proposed, as already mentioned above, that each paper roll is associated with a unique motorized drive.

In a second embodiment of the invention, there is provided only one electric motor for controlling the switching transmission, which switching transmission is alternately switched to the drive of one paper roll or the other. suggest.

All paper towel dispensers are sensor-controlled, that is, when a hand is placed under the paper towel dispenser, the sensor detects this and in each case activates the rotary drive of the active paper roll. is important.

With respect to the time span for the operation of the rotary drive, it is controlled how long the paper towel is dispensed until the cutting device is activated.

Furthermore, in order to prevent the paper towel from falling onto the floor without being used when the paper towel is completely cut, is the strip-shaped paper not cut across its entire width and is it simply provided with a perforation hole? It is important that the cutting device is configured so that a part is cut.

By partially cutting the strip of paper,
The paper towel even hangs on a strip of paper and can be easily torn off by hand.

The subject of the invention lies not only in the features stated in the claims of the claims, but also in the mutual combination of the features of the claims. The problems and features of the invention disclosed in the specification (including the abstract), particularly the three-dimensional shape shown in the drawings, is as long as they are individually or in combination as compared with the prior art. Belong to the frame of.

The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this case, further features and advantages of the invention can be seen from the figures and their description.
