Definitions
- the present invention relates to a paper dispenser with a paper input area and a paper output area.
- the invention relates to a paper dispenser for public restrooms.
- the paper dispenser of the present invention relates to a paper dispenser wherein the paper is fed from a paper roll.
- US2015/0090832 describes a sheet product dispenser with a loading station and a sheet feeding mechanism.
- US2017/0188759 describes a sheet prouct dispenser for dispensing individual sheets from a roll of perforated sheet product.
- Drawbacks of known paper dispensers are related to the amount of paper that is dispensed in one dispensing step. Many paper dispensers lack a mechanism to control the amount of paper dispensed. This leads to excessive use of paper and consequently high maintenance costs of the paper dispenser. Other drawbacks relate to compatibility with different types of paper rolls. The majority of paper dispensers are only suitable for dispensing paper from one type of paper roll. Both the size of the paper roll, including width of the paper roll and thickness of the paper roll is predetermined and significant deviations are not allowed since it cannot be processed by the paper dispenser. Furthermore, the thickness and strength of the paper itself is predetermined. Other drawbacks relate to reliability of the paper dispensers. Many paper dispensers suffer from paper jam issues which affect the uptime of the paper dispenser. Furthermore, it significantly increases the operation costs since an operator is needed to remove the jammed paper and restore the operating mode of the paper dispenser.
- the invention provides a paper dispenser comprising a paper input area and a paper output area; the paper input area comprising a holder for a paper roll and comprising a paper input unit provided to displace paper from the paper roll towards the paper output area, the paper output area comprising a paper output unit which is adapted to dispense paper to an outside of the dispenser, the dispenser further comprising a paper cutting unit arranged between the paper input unit and a paper output unit, which paper cutting unit is adapted for cutting the paper, wherein the paper output unit is operationally connected to the paper input unit to dispense the paper at a dispensing speed that is larger than a displacing speed of the paper input unit.
- the paper dispenser of the invention is provided with a paper input unit and a paper output unit. Between the paper input unit and the paper output unit, a paper cutting unit is provided. The paper is cut by the paper cutting unit so that the dispensed amount of paper is controllable.
- the paper input area comprises a paper roll and a paper input unit. The paper input unit displaces paper from the paper roll towards the paper output area.
- the paper output area comprises a paper dispensing unit which dispenses the paper to an outside of the paper dispenser. There, a user can grab the dispensed paper and use the paper, for example to clean or dry his/her hands.
- a certain tension is preferably applied to the paper between the paper input unit and the paper output unit.
- This tension significantly simplifies the cutting of the paper via the paper cutting unit.
- This tension is obtained by relating the dispensing speed of the paper output unit with the displacing speed of the paper input unit.
- the dispensing speed is at least as large as the displacing speed.
- the dispensing speed is slightly larger than the displacing speed such that the paper output unit pulls (harder) on the paper than the paper input unit. Paper under tension can be cut easily so that jams as a result of miscutting the paper are avoided.
- the holder comprises at least one slot and at least one plug adapted to be received in the at least one slot
- the paper dispenser further comprising a paper roll which is compatible with at least one plug to be connected thereto in such a manner that the paper roll is connectable to the holder via the at least one plug. Since a plug is provided as an intermediate between the paper roll and the holder, a simple technical set-up is obtained that allows to connect paper rolls with different widths in the holder. Since the paper roll is not directly connected to the holder, different types and sorts of paper roll can be connected to the holder via different plugs or via plugs that are shaped to allow connection with different paper rolls.
- the slot and plug have a compatible shape allowing the plug to fit in the slot in at least two positions.
- one position relates to a paper roll with a first width
- a second position relates to a paper roll with a second width which is smaller than the first width.
- the plug being able to be fitted in the slot in at least two positions allows a single plug to be used to connect paper rolls with different shapes and properties to the holder.
- the paper dispenser can also be formed to fit the plug at different heights or at different positions with respect to the holder to allow paper rolls with a larger diameter to be fitted in a preferred position in the paper dispenser.
- the plug comprises a first segment and a second segment, wherein the first segment is adapted for connecting to the paper roll, and wherein the second segment comprises the compatible shape.
- the first segment connects to the paper roll, for example by sliding at least a part of the first segment into a hollow shaft of the paper roll.
- connection means are provided that are compatible with connection means at the paper roll to connect the paper roll with the plug.
- the second segment of the plug is adapted for connecting to the slot, as described above, in multiple positions with respect to the slot.
- the plug is formed about a longitudinal axis, wherein the compatible shape allows the plug to be fitted in the slot in a first position along the longitudinal axis and at a second position located at a first distance from the first position. The first distance is being measured along the longitudinal axis.
- the first segment has a protrusion to engage the paper roll over a second distance that is at least larger than the first distance. Due to the protrusion engaging the paper roll, the plug and paper roll can be interconnected with different relative positions, depending on how deep the protrusion engages the paper roll.
- the range to connect the paper roll and the plug stretches over this second distance. Because this second distance is larger than the first distance, relating to the different positions with respect to the slot, the paper roll should not have a predetermined distance to be able to be fitted in the holder. Depending on the width of the paper roll, the plug engages with the protrusion in the paper roll and is fitted in a slot that optimally corresponds to the width of the paper roll. This will be further explained in the detailed description and with reference to the figures.
- the holder is symmetrical and comprises two opposing slots and two plugs.
- the symmetrical shape allows the roll to be mounted in a central part of the paper dispenser. Furthermore, by providing two slots and two plugs opposing each other, the range of different widths of the paper roll that can be mounted in the paper dispenser increases or is even doubled.
- the paper input is adapted to allow a slip of the paper in the unit and the dispensing speed is larger than the displacing speed.
- the technical choice to make the dispensing speed larger than the displacing speed ensures that a tension is applied to the paper between the input unit and the output unit.
- a tension that is too large could tear the paper. Therefore, the input unit is adapted to allow a slip of the paper in the unit.
- the tension would increase above a predetermined tension, the paper slips so that the tension can be controlled and unwanted tearing of the paper is avoided.
- the resistance against slip of the paper in the paper input unit is lower than the resistance against slip of the paper in the paper output unit.
- a sensor is provided in the paper dispenser to measure the length of the paper dispensed.
- the paper cutting unit is operated based on the sensor. This allows controlling the amount of paper dispensed by the paper dispenser in a dispensing step.
- the paper cutting unit comprises a blade mounted on a shaft so that the blade is moveable, by rotation of a shaft from a retracted position to a paper cutting position.
- the shaft is further preferably controllable to control the moment of cutting of the paper in the process. This allows to control the amount of dispensed paper.
- the shaft with blade is replaceable.
- different types of blades can be inserted in the paper dispenser which allows the paper dispensers to be filled with different types of paper.
- different types of paper often require different types and shapes of cutting blades for optimally cutting the paper.
- the paper dispenser is designed for different types of paper rolls, different widths of paper rolls and different types of paper without significant amendments of the paper dispenser.
- Figure 1 shows a paper dispenser according to a preferred embodiment of the invention.
- the upper part of the paper dispenser 1 comprises the paper input area 2, and the lower part of the paper dispenser 1 comprises the paper output area 3.

- a detection lever 6 is provided, which is spring loaded to lean against the outer periphery of a paper roll in the holder. Via the detection lever 6, an amount of remaining paper in the paper dispenser can be detected.
- a paper roll according to the invention typically comprises a cylindrical central core, around which paper is rolled. This paper typically forms a continuous sheet of paper having a width that corresponds to the width length of the paper roll. Since the paper is continuous, it has to be cut to dispense a predetermined amount of paper. The mechanism to cut the paper is described hereunder.
- the lower segment of the paper input area 2 comprises a paper input unit 4.
- the primary function of the paper input unit 4 is to transfer the paper from the paper roll towards the paper output area 3.
- the paper input unit 4 comprises paper stopper rollers 8.
- the paper stopper rollers 8 are adapted to stop the throughput of paper through the input unit 4.
- the paper stopper rollers 8 are installed in the compression bar with elastic press rod and helps the paper to move smoothly between the driving shaft and the driven shaft.

To this end, the arms 14 comprise a snap fit connection that is compatible with the main body of the paper dispenser 1, such that the arms 14 can be connected and disconnected from the paper dispenser 1. This allows the paper dispenser 1 to be provided with different types of arms 14. Arms 14 can have different lengths, different slots 15, or different shapes, for example an S shape to bring the slots 15, at the distal end of the arms 14, closer to each other.
- arms 14 are straight and extend upward from the main body of the paper dispenser 1.
- the arms 14 are provided with slots 15 which are U shaped to receive a plug 10 with a compatible shape.
- a notch is provided that fits in a groove 11 at the plug 10.
- the plug 10 can be positioned in the slot 15.
- the plug 10 comprises multiple grooves 11, in particular three grooves 11, which are provided at a distance of each other. This allows the plug 10 to be connected in the slot 15 at multiple, in particular three different positions. These different positions enable an operator to vary the distance between one plug and an opposing plug. Varying this distance allows to mount paper rolls having different roll lengths (measured in the direction of the center axis of the roll) in the paper dispenser without the necessity of adapting the paper roll, using different plugs 10 or changing the arms 14.
- the plug 10 comprises two segments.
- a first segment 12 comprises protrusions which are provided to engage with a paper roll.
- the center core of the paper roll is hollow, so that a round, typically cylindrical, optionally tapered protrusion is sufficient as a first segment to mount the paper roll in the paper dispenser 1.

- the plug 10 comprises a main body 17 with a collar and the second part comprises a paper roll core 18.
- This paper roll core is preferably changeable or replaceable so that different paper roll cores corresponding to different types of paper rolls can be connected in the main body 17.
- This paper roll core 18 could interconnect with a proprietary plug of the core of the paper roll, shown as element 19.
- This proprietary plug can be a fixed part of the paper roll, or can be adapted to optimally engage with the paper roll.
- the set-up described above allows to interconnect different types of paper rolls in an optimal manner to the paper dispenser 1.
- the multiple elements described above are interchangeable so that only minimal adaptations are necessary to connect a paper roll of a different type.
- Figure 3 shows the paper dispenser 1 wherein the left side of the paper dispenser 1 is open to reveal the elements driving the paper through the paper dispenser 1.
- the paper shows a paper driving motor 35 which is connected to multiple gears that drive the paper input unit and the paper output unit as will be described further below.
- Figure 3 further illustrates a sensor 20 to control the length of the dispensed piece of paper. Between the paper input unit 4 and the paper output unit 5, a paper cutting unit is provided, which is described in greater detail hereunder.
- the sensor 20 is adapted to measure the length of the amount of paper that is dispensed by the paper output unit.
- This measurement can be used in a processor to control the paper input unit and paper output unit as well as to control the paper cutting unit, such that a predetermined amount of paper, or a predetermined length of paper, is dispensed in one dispensing step.
- the sensor 20 is formed as an infrared sensor that measures the rotation of one of the rollers of the paper output unit. The skilled person will understand that other types of sensors can be used to measure the amount of paper dispensed.
- Figure 3 further shows cut of type infrared sensors at a dispensing opening of the output unit. Via these sensors, removal of the piece of dispenses paper can be detected so that, upon receipt of an input via the sensor 9, a successive dispensing step can be started. When the sensors 21 detect that the paper has not been removed yet, such successive dispensing step can be delayed or blocked.
- FIG 4 shows the paper dispenser with an opened right hand side. Furthermore, in figure 4 the front panel of the paper dispenser is partly removed from the main body. This front panel comprises multiple quick release clamps which are compatible with the main body, so that the front panel can be removed from the paper dispenser. This opens the paper dispenser. The primary reason for opening the paper dispenser is to replace the paper cutting unit, as will be further described hereunder. Another reason to open the paper dispenser is to clean the dispenser, for example remove residual paper.
- the main body of the paper dispenser comprises a front cover safety switch 23. This switch detects removal of the front cover such that the operation of the paper dispenser can be stopped. This improves that safety of the paper dispenser. In the paper dispenser a paper cutting unit is provided which could harm to a user opening the front panel when the paper dispenser is in an operating mode. Via the switch 23, the dispenser is set to a maintenance mode wherein uncontrolled or unwanted movement or elements in the paper dispenser is prevented.

- Figure 4 further shows a sensor for detecting the position of the blade.
- the sensor preferably is an infrared sensor connected to a shaft of the paper cutting unit.
- the sensor output can be used by a controller to control the cutting of the paper. As described above, this allows to control the length or amount of paper which is dispensed in one dispensing step.
- FIG. 5 shows the paper cutting unit.
- the paper cutting unit comprises a shaft 26 and one or multiple blades 25 that are provided on a periphery of the shaft 26.
- the blades are preferably mounted tangential with respect to the shaft 26.
- the shape of the blades 25 is preferably optimized to cut paper. Depending on the type of paper that is dispensed by the dispenser, the blade can have different shapes. In the shown embodiment, the blades do not extend over the complete width of the paper, but are placed to only cut the paper over a predetermined percentage of the width, preferably at least 70%, more preferably at least 80% of the width of the paper. This allows a piece of paper to be partly separated from the roll so that a user can remove the piece of paper from the roll with minimum effort. Since the paper is already partly cut, tearing the piece of paper from the paper roll by tearing the remaining part of the width of the paper is easy. Furthermore, not completely cutting the paper simplifies the throughput of paper through the paper dispenser 1.
- the shaft 26 and blade or blades 25 are preferably provided on a connector 27. Most preferably, two connectors 27 are provided at opposing ends of the shaft 26 so that the paper cutting unit formed by the connectors, the shaft and the blade can be removably connected to the body of the paper dispenser. Removing the paper cutting unit is illustrated by arrow 28 in figure 5 .
- the paper cutting unit replaceable not only paper dispenser is simplified, but it also allows the paper dispenser to be used with different types of paper. As described above, different types of paper may require different types of cutter blades to optimally cut the paper. The cutting blades can be easily switched by replacing the paper cutting unit.
- Figure 6 shows a schematic cross section of the paper dispenser, and shows from top to bottom how the paper is input 29 into the paper input unit.
- the paper input 29 comes from a paper roll which is not shown in this figure.
- This paper is input into paper input unit 4 having multiple input rollers 33.
- the input rollers 33 displace the paper from the paper roll towards the paper output unit 5.
- Paper output unit 5 comprises multiple output rollers 34. Between the paper input unit 4 and the paper output unit 5, the paper cutting unit is provided.
- the paper cutting unit is formed by the shaft 26 and the cutting blade 25.
- Figure 6 illustrates how the cutting blade can be retracted by retracting rotation 32.
- the figure also shows how the paper can be cut by a cutting rotation 31.
- the skilled person will understand that by controlling the input unit, the output unit and the paper cutting unit, the length of the pieces of paper that are dispensed at the output can be controlled.
- the output is illustrated by arrow 30.
- a tension is maintained on the paper between the paper input unit 4 and the paper output unit 5.
- This tension can be maintained by controlling the paper throughput speed of the paper input unit with respect to the paper output unit.
- the paper output unit 5 preferably has a slightly higher throughput than the paper input unit 4 such that the paper output unit 5 effectively pulls the paper through the paper input unit 4. This pulling results in a tensioning of the paper between the paper input unit and the paper output unit. This tension significantly simplifies the cutting of the paper by the blades 25.
- the input rollers 33 and the output rollers 34 are preferably driven by the paper driving motor 35 and the gears which are shown in figure 3 .
- the shaft 26 of the paper cutting unit is preferably driven by the blade driving motor 36 and the gears which are shown in figure 4 . This allows to independently control the throughput of the paper and the cutting of the paper, which thereby allows to dispense any length or any amount of paper. Thus the operator of the paper dispenser 1 is free to configure the dispenser as he or she wishes.
- Figure 7 shows an exploded via of the paper dispenser 1 according to a preferred embodiment of the invention.
- the figure shows the main frame 43 of the dispenser, having a bottom cover 44. All other elements are adapted to directly or indirectly connect to the main frame 43 to form the paper dispenser.
- the figure shows the paper driving motor 35 which is connected to a paper input gear set 38 via a belt transmission 37. Via the belt transmission 37, the paper driving motor is further connected to the paper output gear set 39.
- the advantage of using a belt transmission 37 is that noise is reduced. Using this configuration a single motor 35 can be used to transport the paper through the paper dispenser.
- the paper input gear set is connected to multiple paper input rollers 33.
- Paper output gear set 39 is connected to the paper output rollers 34.
- the elements are interconnected at the left-hand side via a left fixing plate 40.
- FIG. 7 further shows that blade driving motor 36 which is connected to the blade driving gear set 42 via a belt transmission 37.
- the blade driving gear set is connected to the shaft 26 carrying the cutting blade 25. Using this set-up, the shaft 26 and the blade 25 can be driven by the blade driving motor. The different elements are held together via the right fixing plate 41.
- Figure 7 further shows the replaceable arms 14 adapted for holding the plug 10. Via these plugs, a paper roll can be connected to the paper dispenser. The thickness of the roll is detected via the detection lever 6.
- Paper dispenser 1 further comprises a battery compartments 7 which provides power to the blade driving motor 36, the paper driving motor 35 and the controllers.

This tension significantly simplifies the cutting of the paper via the paper cutting unit. This tension is obtained by relating the dispensing speed of the paper output unit with the displacing speed of the paper input unit. In practice, the dispensing speed is at least as large as the displacing speed. Preferably, the dispensing speed is slightly larger than the displacing speed such that the paper output unit pulls (harder) on the paper than the paper input unit. Paper under tension can be cut easily so that jams as a result of miscutting the paper are avoided.
- Preferably the holder comprises at least one slot and at least one plug adapted to be received in the at least one slot, the paper dispenser further comprising a paper roll which is compatible with at least one plug to be connected thereto in such a manner that the paper roll is connectable to the holder via the at least one plug. Since a plug is provided as an intermediate between the paper roll and the holder, a simple technical set-up is obtained that allows to connect paper rolls with different widths in the holder. Since the paper roll is not directly connected to the holder, different types and sorts of paper roll can be connected to the holder via different plugs or via plugs that are shaped to allow connection with different paper rolls.
- Preferably, the slot and plug have a compatible shape allowing the plug to fit in the slot in at least two positions. For example one position relates to a paper roll with a first width, while a second position relates to a paper roll with a second width which is smaller than the first width. The plug being able to be fitted in the slot in at least two positions allows a single plug to be used to connect paper rolls with different shapes and properties to the holder. Thereby, the paper dispenser can also be formed to fit the plug at different heights or at different positions with respect to the holder to allow paper rolls with a larger diameter to be fitted in a preferred position in the paper dispenser.
- Preferably, the plug comprises a first segment and a second segment, wherein the first segment is adapted for connecting to the paper roll, and wherein the second segment comprises the compatible shape. The first segment connects to the paper roll, for example by sliding at least a part of the first segment into a hollow shaft of the paper roll. Alternatively, connection means are provided that are compatible with connection means at the paper roll to connect the paper roll with the plug. The second segment of the plug is adapted for connecting to the slot, as described above, in multiple positions with respect to the slot.
- Preferably, the plug is formed about a longitudinal axis, wherein the compatible shape allows the plug to be fitted in the slot in a first position along the longitudinal axis and at a second position located at a first distance from the first position. The first distance is being measured along the longitudinal axis. This allows the plug to connect paper rolls with different distances to the holder by positioning the plug in the different positions along the longitudinal axis. Further preferably, the first segment has a protrusion to engage the paper roll over a second distance that is at least larger than the first distance. Due to the protrusion engaging the paper roll, the plug and paper roll can be interconnected with different relative positions, depending on how deep the protrusion engages the paper roll. Since it is able to engage the paper roll over the second distance, the range to connect the paper roll and the plug stretches over this second distance. Because this second distance is larger than the first distance, relating to the different positions with respect to the slot, the paper roll should not have a predetermined distance to be able to be fitted in the holder. Depending on the width of the paper roll, the plug engages with the protrusion in the paper roll and is fitted in a slot that optimally corresponds to the width of the paper roll. This will be further explained in the detailed description and with reference to the figures.
- Preferably, the holder is symmetrical and comprises two opposing slots and two plugs. The symmetrical shape allows the roll to be mounted in a central part of the paper dispenser. Furthermore, by providing two slots and two plugs opposing each other, the range of different widths of the paper roll that can be mounted in the paper dispenser increases or is even doubled.
- In accordance with
claim 1, the paper input is adapted to allow a slip of the paper in the unit and the dispensing speed is larger than the displacing speed. The technical choice to make the dispensing speed larger than the displacing speed ensures that a tension is applied to the paper between the input unit and the output unit. However, a tension that is too large could tear the paper. Therefore, the input unit is adapted to allow a slip of the paper in the unit. When the tension would increase above a predetermined tension, the paper slips so that the tension can be controlled and unwanted tearing of the paper is avoided. Thereby, further preferably, the resistance against slip of the paper in the paper input unit is lower than the resistance against slip of the paper in the paper output unit. - Preferably, a sensor is provided in the paper dispenser to measure the length of the paper dispensed. In this context, further preferably the paper cutting unit is operated based on the sensor. This allows controlling the amount of paper dispensed by the paper dispenser in a dispensing step.
- Preferably, the paper cutting unit comprises a blade mounted on a shaft so that the blade is moveable, by rotation of a shaft from a retracted position to a paper cutting position. The shaft is further preferably controllable to control the moment of cutting of the paper in the process. This allows to control the amount of dispensed paper.
- Further preferably, the shaft with blade is replaceable. By replacing the shaft and the blade, different types of blades can be inserted in the paper dispenser which allows the paper dispensers to be filled with different types of paper. In this context, it is noted that different types of paper often require different types and shapes of cutting blades for optimally cutting the paper. With this technical set-up, as described above, the paper dispenser is designed for different types of paper rolls, different widths of paper rolls and different types of paper without significant amendments of the paper dispenser.

Figure 1 shows a paper dispenser according to a preferred embodiment of the invention. The upper part of thepaper dispenser 1 comprises thepaper input area 2, and the lower part of thepaper dispenser 1 comprises thepaper output area 3. Thepaper input area 2 has two segments. The upper segment of thepaper input area 2 comprises a holder for holding a paper roll (not shown). The holder will be described in further detail with reference tofigure 2 . Preferably, a detection lever 6 is provided, which is spring loaded to lean against the outer periphery of a paper roll in the holder. Via the detection lever 6, an amount of remaining paper in the paper dispenser can be detected. A paper roll according to the invention typically comprises a cylindrical central core, around which paper is rolled. This paper typically forms a continuous sheet of paper having a width that corresponds to the width length of the paper roll. Since the paper is continuous, it has to be cut to dispense a predetermined amount of paper. The mechanism to cut the paper is described hereunder. - The lower segment of the
paper input area 2 comprises apaper input unit 4. The primary function of thepaper input unit 4 is to transfer the paper from the paper roll towards thepaper output area 3. Thepaper input unit 4 comprisespaper stopper rollers 8. Thepaper stopper rollers 8 are adapted to stop the throughput of paper through theinput unit 4. Thepaper stopper rollers 8 are installed in the compression bar with elastic press rod and helps the paper to move smoothly between the driving shaft and the driven shaft. Thepaper input unit 4 further comprises a set of rollers and a set of gears to drive the rollers, as well as a motor, which are described hereunder with reference to further figures. - The
paper output area 3 comprises apaper output unit 5. Infigure 1 , the paper dispensing guide is shown, which dispensing guide is part of the paper output area. Thepaper output unit 5 further comprises a set of rollers and corresponding gears to drive the rollers connected to a motor, for dispensing paper to an outer side of thedispensing unit 1. These elements are described in more detail hereunder. The primary function of the paper output unit is to dispense paper to an outer side of thedispensing unit 1, where a user can grab the paper. The paper is received from thepaper input unit 4.Figure 1 further shows asensor 9 which in the embodiment offigure 1 is formed as a field or an area which is touch sensitive. Via thesensor 9, operation of thedispenser 1 can be triggered. Thepaper dispenser 1 can be configured to perform one or a predetermined number of paper dispensing steps after input is received from thesensor 9. The skilled person will realize that atouch sensor 9 is only an embodiment, and other types of sensors, for example a push button, can be equally used. -
Figure 2 shows a detailed embodiment of the upper part of thepaper input area 2 of thepaper dispenser 1 offigure 1 . This upper part comprises the holder for the paper roll (not shown). The paper holder is formed by twoarms 14 that extend upward from the main body of thepaper dispenser 1. Thesearms 14 are preferably replaceable. To this end, thearms 14 comprise a snap fit connection that is compatible with the main body of thepaper dispenser 1, such that thearms 14 can be connected and disconnected from thepaper dispenser 1. This allows thepaper dispenser 1 to be provided with different types ofarms 14.Arms 14 can have different lengths,different slots 15, or different shapes, for example an S shape to bring theslots 15, at the distal end of thearms 14, closer to each other. - In the embodiment of
figure 2 arms 14 are straight and extend upward from the main body of thepaper dispenser 1. Thearms 14 are provided withslots 15 which are U shaped to receive aplug 10 with a compatible shape. In the U shapedslot 15, a notch is provided that fits in agroove 11 at theplug 10. Via the notch and groove theplug 10 can be positioned in theslot 15. In the embodiment offigure 2 , theplug 10 comprisesmultiple grooves 11, in particular threegrooves 11, which are provided at a distance of each other. This allows theplug 10 to be connected in theslot 15 at multiple, in particular three different positions. These different positions enable an operator to vary the distance between one plug and an opposing plug. Varying this distance allows to mount paper rolls having different roll lengths (measured in the direction of the center axis of the roll) in the paper dispenser without the necessity of adapting the paper roll, usingdifferent plugs 10 or changing thearms 14. - The
plug 10 comprises two segments. Afirst segment 12 comprises protrusions which are provided to engage with a paper roll. Typically the center core of the paper roll is hollow, so that a round, typically cylindrical, optionally tapered protrusion is sufficient as a first segment to mount the paper roll in thepaper dispenser 1. Alternatively, the first segment comprises clamp means (not shown) which correspond to compatible connecting means at the paper roll for connecting theplug 10 to the paper roll. Thefirst segment 12 is preferably separated from asecond segment 13 by a collar, as is shown in the figures. Thesecond segment 13 comprises thegrooves 11. The skilled person will understand that the groove-notch connection can be reversed so that thesecond segment 13 is provided with one or multiple notches while theslot 15 is provided with the groove or grooves. - At the right hand side of the figure, an exploded view is shown of the
plugs 10. In this embodiment, theplug 10 comprises amain body 17 with a collar and the second part comprises apaper roll core 18. This paper roll core is preferably changeable or replaceable so that different paper roll cores corresponding to different types of paper rolls can be connected in themain body 17. Thispaper roll core 18 could interconnect with a proprietary plug of the core of the paper roll, shown aselement 19. This proprietary plug can be a fixed part of the paper roll, or can be adapted to optimally engage with the paper roll. The set-up described above allows to interconnect different types of paper rolls in an optimal manner to thepaper dispenser 1. The multiple elements described above are interchangeable so that only minimal adaptations are necessary to connect a paper roll of a different type. -
Figure 3 shows thepaper dispenser 1 wherein the left side of thepaper dispenser 1 is open to reveal the elements driving the paper through thepaper dispenser 1. In particular, the paper shows apaper driving motor 35 which is connected to multiple gears that drive the paper input unit and the paper output unit as will be described further below.Figure 3 further illustrates asensor 20 to control the length of the dispensed piece of paper. Between thepaper input unit 4 and thepaper output unit 5, a paper cutting unit is provided, which is described in greater detail hereunder. Thesensor 20 is adapted to measure the length of the amount of paper that is dispensed by the paper output unit. This measurement can be used in a processor to control the paper input unit and paper output unit as well as to control the paper cutting unit, such that a predetermined amount of paper, or a predetermined length of paper, is dispensed in one dispensing step. In the embodiment offigure 3 , thesensor 20 is formed as an infrared sensor that measures the rotation of one of the rollers of the paper output unit. The skilled person will understand that other types of sensors can be used to measure the amount of paper dispensed. -
Figure 3 further shows cut of type infrared sensors at a dispensing opening of the output unit. Via these sensors, removal of the piece of dispenses paper can be detected so that, upon receipt of an input via thesensor 9, a successive dispensing step can be started. When thesensors 21 detect that the paper has not been removed yet, such successive dispensing step can be delayed or blocked. -
Figure 4 shows the paper dispenser with an opened right hand side. Furthermore, infigure 4 the front panel of the paper dispenser is partly removed from the main body. This front panel comprises multiple quick release clamps which are compatible with the main body, so that the front panel can be removed from the paper dispenser. This opens the paper dispenser. The primary reason for opening the paper dispenser is to replace the paper cutting unit, as will be further described hereunder. Another reason to open the paper dispenser is to clean the dispenser, for example remove residual paper. The main body of the paper dispenser comprises a frontcover safety switch 23. This switch detects removal of the front cover such that the operation of the paper dispenser can be stopped. This improves that safety of the paper dispenser. In the paper dispenser a paper cutting unit is provided which could harm to a user opening the front panel when the paper dispenser is in an operating mode. Via theswitch 23, the dispenser is set to a maintenance mode wherein uncontrolled or unwanted movement or elements in the paper dispenser is prevented. -
Figure 4 further shows theblade driving motor 36 connected via a number of gears to the shaft carrying the blades for cutting the paper, which will be described hereunder.Figure 4 further shows a sensor for detecting the position of the blade. The sensor preferably is an infrared sensor connected to a shaft of the paper cutting unit. The sensor output can be used by a controller to control the cutting of the paper. As described above, this allows to control the length or amount of paper which is dispensed in one dispensing step. -
Figure 5 shows the paper cutting unit. The paper cutting unit comprises ashaft 26 and one ormultiple blades 25 that are provided on a periphery of theshaft 26. The blades are preferably mounted tangential with respect to theshaft 26. The shape of theblades 25 is preferably optimized to cut paper. Depending on the type of paper that is dispensed by the dispenser, the blade can have different shapes. In the shown embodiment, the blades do not extend over the complete width of the paper, but are placed to only cut the paper over a predetermined percentage of the width, preferably at least 70%, more preferably at least 80% of the width of the paper. This allows a piece of paper to be partly separated from the roll so that a user can remove the piece of paper from the roll with minimum effort. Since the paper is already partly cut, tearing the piece of paper from the paper roll by tearing the remaining part of the width of the paper is easy. Furthermore, not completely cutting the paper simplifies the throughput of paper through thepaper dispenser 1. - The
shaft 26 and blade orblades 25 are preferably provided on aconnector 27. Most preferably, twoconnectors 27 are provided at opposing ends of theshaft 26 so that the paper cutting unit formed by the connectors, the shaft and the blade can be removably connected to the body of the paper dispenser. Removing the paper cutting unit is illustrated byarrow 28 infigure 5 . By making the paper cutting unit replaceable, not only paper dispenser is simplified, but it also allows the paper dispenser to be used with different types of paper. As described above, different types of paper may require different types of cutter blades to optimally cut the paper. The cutting blades can be easily switched by replacing the paper cutting unit. -
Figure 6 shows a schematic cross section of the paper dispenser, and shows from top to bottom how the paper isinput 29 into the paper input unit. Thepaper input 29 comes from a paper roll which is not shown in this figure. This paper is input intopaper input unit 4 havingmultiple input rollers 33. Theinput rollers 33 displace the paper from the paper roll towards thepaper output unit 5.Paper output unit 5 comprisesmultiple output rollers 34. Between thepaper input unit 4 and thepaper output unit 5, the paper cutting unit is provided. The paper cutting unit is formed by theshaft 26 and thecutting blade 25. -
Figure 6 illustrates how the cutting blade can be retracted by retractingrotation 32. The figure also shows how the paper can be cut by a cuttingrotation 31. The skilled person will understand that by controlling the input unit, the output unit and the paper cutting unit, the length of the pieces of paper that are dispensed at the output can be controlled. The output is illustrated byarrow 30. Preferably, to optimize the operation of the paper cutting unit, a tension is maintained on the paper between thepaper input unit 4 and thepaper output unit 5. This tension can be maintained by controlling the paper throughput speed of the paper input unit with respect to the paper output unit. In particular, thepaper output unit 5 preferably has a slightly higher throughput than thepaper input unit 4 such that thepaper output unit 5 effectively pulls the paper through thepaper input unit 4. This pulling results in a tensioning of the paper between the paper input unit and the paper output unit. This tension significantly simplifies the cutting of the paper by theblades 25. - The
input rollers 33 and theoutput rollers 34 are preferably driven by thepaper driving motor 35 and the gears which are shown infigure 3 . Theshaft 26 of the paper cutting unit is preferably driven by theblade driving motor 36 and the gears which are shown infigure 4 . This allows to independently control the throughput of the paper and the cutting of the paper, which thereby allows to dispense any length or any amount of paper. Thus the operator of thepaper dispenser 1 is free to configure the dispenser as he or she wishes. -
Figure 7 shows an exploded via of thepaper dispenser 1 according to a preferred embodiment of the invention. The figure shows themain frame 43 of the dispenser, having abottom cover 44. All other elements are adapted to directly or indirectly connect to themain frame 43 to form the paper dispenser. The figure shows thepaper driving motor 35 which is connected to a paper input gear set 38 via abelt transmission 37. Via thebelt transmission 37, the paper driving motor is further connected to the paper output gear set 39. The advantage of using abelt transmission 37 is that noise is reduced. Using this configuration asingle motor 35 can be used to transport the paper through the paper dispenser. The paper input gear set is connected to multiplepaper input rollers 33. Paper output gear set 39 is connected to thepaper output rollers 34. The elements are interconnected at the left-hand side via aleft fixing plate 40. -
Figure 7 further shows thatblade driving motor 36 which is connected to the blade driving gear set 42 via abelt transmission 37. The blade driving gear set is connected to theshaft 26 carrying thecutting blade 25. Using this set-up, theshaft 26 and theblade 25 can be driven by the blade driving motor. The different elements are held together via theright fixing plate 41. -
Figure 7 further shows thereplaceable arms 14 adapted for holding theplug 10. Via these plugs, a paper roll can be connected to the paper dispenser. The thickness of the roll is detected via the detection lever 6.Paper dispenser 1 further comprises a battery compartments 7 which provides power to theblade driving motor 36, thepaper driving motor 35 and the controllers. The controllers are typically integrated in theoperation panel 46. Operation panel can be mounted onto aquick release frame 45. The operation panel holds thepaper stopper rollers 8. - The scope of the invention is defined by the appended claims 1.
