- Preferred embodiments in accordance with the present invention will now be described with reference to the accompanying drawings.
- Referring to Fig. 2, a roll of
tissue paper 4 used with a tissue paper dispenser in accordance with the present invention is made of natural fibers, artificial fibers, synthetic fibers, etc.Sensor marks 42 are provided on a side of the roll oftissue paper 4 and spaced at regular intervals. Eachsensor mark 42 is a notch or a sensor means attached to the side of the roll oftissue paper 4 by means of printing, bonding, or other suitable means.Breaking lines 41 may be provided on the roll of tissue paper and spaced at regular intervals, allowing flush breaking of the tissue paper. Further, in a case that the tissue paper is made of artificial fibers or synthetic fibers, a pressedportion 43 can be provided on each side of each breakingline 41 by means of hot melting in order to prevent of falling of fibers. - Referring to Figs. 2 and 3, the tissue paper dispenser in accordance with the present invention comprises a
casing 3, a first set ofrollers 1, and a second set ofrollers 2. Thetissue paper 4 is passed through the first and second sets ofrollers casing 3 comprises at least twosidewalls 31 between which the first and second sets ofrollers means 32 is mounted on thecasing 3 for mating with thesensor mark 42 on the roll oftissue paper 4. When asensor mark 42 is passed through the detectingmeans 32, the detectingmeans 32 sends a signal, which will be described in detail later. The detecting means 32 may be a conventional photo sensor. In order to allow easy entrance of thetissue paper 4 into the first and second sets ofrollers guide plates 33 are mounted between the sidewalls 31 and respectively located above the first and second sets ofrollers conventional sprayer 34 can be mounted in thecasing 3 to wet thetissue paper 4 passing therethrough. Further, in order to guide thetissue paper 4 out of thecasing 3, aguide plate 35 is mounted below the second set of therollers 2. - The first set of
rollers 1 includes at least tworollers sidewalls 31. The surfaces of therollers roller 11 is in contact with or almost in contact with the surface of theroller 12. Transmittingmembers 13 such as gears are provided to make therollers tissue paper 4 to pass through theroller 11 and theroller 12 to the second set ofrollers 2. Therollers rollers 1 are driven by apower device 14. - The second set of
rollers 2 is located below or behind the second set ofrollers 1 and includes at least tworollers sidewalls 31 of thecasing 3. The surfaces of therollers roller 21 is in contact with or almost in contact with the surface of theroller 22. Transmittingmembers 23 such as gears are provided to make therollers tissue paper 4 to pass through theroller 21 and theroller 22 and to move downward. Therollers rollers 2 are driven by apower device 24. - Referring to Figs. 3 and 4, a distal end of the roll of
tissue paper 4 is passed through therollers rollers 1 and through therollers rollers 2. The distal end of the roll oftissue paper 4 is moved downward by the rotational movements of the first and second sets ofrollers rollers 1 rotates at a speed the same as that of the second set ofrollers 2. When thesensor mark 42 on the roll oftissue paper 4 passes through the detectingmeans 32, the detectingmeans 32 sends a signal to stop or reduce the speed of thepower device 14 for the first set ofrollers 1. Thus, a tear force is applied to thetissue paper 4 between the first set ofrollers 1 and the second set ofrollers 2 such that thetissue paper 4 breaks along the breaking line 41 (Fig. 5). The separated piece of thetissue paper 4 falls as a result of continuous rotation of therollers rollers 2 and is then guided out of thecasing 3 by theguide plate 35. - Fig. 6 illustrates a modified embodiment of the tissue paper dispenser in accordance with the present invention, wherein a
clutch wheel 36 is mounted to thecasing 3 and controlled by acontroller 37 such as an electromagnetic valve. When thesensor mark 42 passes through the detectingmeans 32, the detectingmeans 32 sends a signal to disengage theclutch wheel 36 from thetransmission members rollers 1 and the second set ofrollers 2. After a predetermined period of time, theclutch wheel 36 is reengaged with thetransmission members rollers 1 and the second set ofrollers 2. - In this embodiment, no power device is provided for the first set of
rollers 1, yet apower device 24 is provided for the second set ofrollers 2. Thus, when theclutch wheel 36 is reengaged with thetransmission members rollers 1 and the second set of rollers 2 (Fig. 7), therollers rollers 1 and the second set ofrollers 2 rotate at the same speed. Thetissue paper 4 is pulled downward. When theclutch wheel 36 is disengaged from thetransmission member 13 of the first set of therollers 1 and/or thetransmission member 23 of the second set of rollers 2 (Fig. 8), therollers rollers 1 stops rotating, while the second set ofrollers 2 keep rotating by thepower device 24. Thus, a tear force is applied to thetissue paper 4 between the first set ofrollers 1 and the second set ofrollers 2 such that thetissue paper 4 breaks along the breakingline 41. The separated piece of thetissue paper 4 is guided out of thecasing 3 by theguide plate 35. - Fig. 9 is a top view of a second embodiment of the second set of rollers (now designated by 2a). In this embodiment, the second set of
rollers 2a is located below or behind the first set ofrollers 1 and includes tworollers tissue paper 4 to pass therethrough. Eachroller roller bulge section bulge sections bulge section 211a is in contact with or almost in contact with thebulge section 221a. Thus, therollers bulge sections longer hole 411 forming a portion of the breakingline 41 of thetissue paper 4. As a result, when the first set ofrollers 1 and the second set ofrollers 2b rotate at different speeds, a small force provided by the power device (such as a motor) is sufficient to tear the tissue paper apart, best shown in Figs. 10 and 11. - Figs. 12 and 13 illustrates a third embodiment of the second set of rollers (now designated by 2b) comprising two
rollers roller roller section 212b, 222b of a relatively larger uniform diameter. Eachroller conic side section mediate section 212b, 222b. Thus, the surfaces of therollers longer hole 411 forming a portion of the breakingline 41 of the tissue paper 4 (Fig. 13). Further, themediate section 212b, 222b is preferably shorter than the relativelylonger hole 411 of the roll of thetissue paper 4. As a result, when the first set ofrollers 1 and the second set ofrollers 2b rotate at different speeds, a small force provided by the power device (such as a motor) is sufficient to tear the tissue paper apart. - Figs. 14 and 15 illustrate a fourth embodiment of the second set of rollers (now designated by 2c) comprising two
rollers 21c and 22c. Eachroller 21c, 22c has a non-cylindrical surface. In this embodiment, eachroller 21c, 22c is wavelike and has plural bulge sections section 214c, 224c and arecess section rollers 21c and 22c have a relatively smaller contact surface area therebetween. Further, the contact surface area is aligned with the relativelylonger hole 411 forming a portion of the breakingline 41 of thetissue paper 4. As a result, when the first set ofrollers 1 and the second set of rollers 2c rotate at different speeds, a small force provided by the power device (such as a motor) is sufficient to tear the tissue paper apart. - Thus, the present invention provides a method and device for separating the tissue paper in which the manner for dispensing tissue paper is altered. When compared with the conventional tissue paper dispenser, the cutter and corresponding elements are eliminated. The structure and the maintenance therefor are thus simplified, and the assembling procedure is more convenient. Further, the maintenance resulting from the wear of the cutter is also eliminated. Further, the length of each piece of tissue paper to be dispensed can be set during manufacture of the roll of
tissue paper 4, which is convenient when compared with troublesome replacement of gears and motors required in conventional designs. - Further, in accordance with the method and device for separating tissue paper, when the first and second sets of roller rotate at different speeds, the rollers of the second set of rollers have a relatively small contact surface area therebetween such that the tissue paper between the first set of rollers and the second set of rollers can be torn easily. Further, a small force provided by the power device (such as a motor) is sufficient to tear the tissue paper apart; namely, the power consumed by the power device for tearing the tissue paper apart is reduced.
- Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention. It is, therefore, contemplated that the appended claims will cover such modifications and variations that fall within the true scope of the invention.
