Definitions
- This invention relates to a dispenser suitable for dispensing absorbent sheet material from a roll according to the preamble of claim 1 .
- the dispenser is particularly suitable for being installed on a wall for dispensing absorbent sheet material, or wipes, to a user.
- the roll may be a continuous or discontinuous hard wound roll towel.
- the dispenser according to the invention is suitable for dispensing absorbent sheet material from a roll disposable within said dispenser.
- the dispenser comprising: a dispenser body, a rotational shaft suitable for penetration of said roll, a drive unit, and an energy storage system for storing energy.
- the drive unit is rotationally coupled to said rotational shaft, which comprising engagement means suitable for rotationally locking said rotational shaft with said roll. Externally caused rotation of said rotational shaft drives said drive unit, thereby enabling accumulation of energy in said energy storage system, and said drive unit is configured to be powered by energy from said energy storage system for temporarily rotating said rotational shaft.
- the solution according to the invention provides efficient and simple, potentially automatic, rotational locking between the roll and the rotational shaft upon axial penetration of the rotational shaft in the hole of the roll.
- No time consuming and complex additional manual locking of the roll is necessary, and the at least one projection and/or at least one recess potentially prevents erroneous mounting of the roll, for example in that the projection/recess intuitively guides the service personnel to the correct mounting.
- incorrect axial mounting of the roll is mounting is difficult or even impossible when the roll itself is provided with corresponding engagement means.
- the projection/recess may be designed to exhibit automatic rotational locking in corresponding engagement means of the roll after mounting of the roll, optionally first upon rotation of the roll.
- the drive unit may be formed by an electrical machine
- said energy storage system may be formed by an electrical storage system, wherein externally caused rotation of said rotational shaft may drive said electrical machine, thereby enabling generation of electrical energy that may be stored in said electrical storage system, and wherein said electrical machine may be configured to be powered by electrical energy from said electrical storage system for temporarily rotating said rotational shaft .
- the dispenser body may comprise a dispenser console, and a hood pivotally connected to said dispenser console, wherein said rotational shaft being rotatably mounted to said hood or said console.
- the hood may be less rigid and less complex because it does not have to support the drive unit and energy storage system.
- the rotational shaft when the rotational shaft is arranged on the hood, the rotational shaft will project upwardly when tilting the hood 90° forwards, thereby simplifying insertion of a new roll onto the rotational shaft due to gravity and improved handling.
- the at least one retractable radial projection may be mechanically actuated upon pivoting motion of said hood.
- the dispenser may comprise means suitable for registering radial roll size of both said roll and said additional roll, wherein said dispenser being configured to dispense absorbent sheet paper from the roll having the smallest radial roll size.
- the arrangement has the advantage of completely depleting one roll before initiating feeding from the other roll, thereby eliminating any waste of sheet material due to replacement of non-depleted rolls.
- Figure 1 shows a perspective view of the dispenser according to a first embodiment of the invention in a semi-open state
- Figure 2 shows the dispenser of fig. 1 in an open state
- the console 12 which comprises a rear wall of the dispenser 10, is configured to at least partly contact an external wall onto which said dispenser 10 is configured to be installed.
- a longitudinal axis of the rotational shaft 15 is in a closed state of the dispenser 10 arranged substantially perpendicular to a plane defined by the parts of the rear wall of the console 12 that are configured to contact said wall.
- This arrangement serves to have a substantially horizontally arranged rotational shaft 15 when mounted on a substantially vertical wall, as well as allowing easy replacement of the sheet material roll 1 1 , because good access is provided to the roll 1 1 when pivoting the outer and inner hoods 13, 14 of the dispenser 10 to the open position.
- the same effect is realised when the rotational shaft 15 is rotatably connected to the console 12 instead of the inner hood 14.
- the user can grab a leading tail of the sheet material, which is wound on the core 17 to form the roll 1 1.
- the leading tail preferably is arranged at least partly outside the dispenser 10, for example hanging down a certain length through a dispensing opening at the lower part of the dispenser 10.
- the roll 1 1 starts to rotate due to the pulling force actuated by the user, and sheet material is removed from the roll 1 1 .
- Due to the engagement means of the rotational shaft 15 and corresponding engagement means on the core 17, the rotational shaft 15 may be rotationally locked with the roll 1 1 .
- the externally caused rotation of the roll 1 1 consequently causes the rotational shaft 15 to rotate as well.
- the certain length of sheet material being fed is selected to provide a graspable leading tail of the sheet material, such that the user can easily find, grasp and pull the leading tail next occasion sheet material is requested.
- the leading tail of the sheet material is likely difficult the find and difficult to grasp, because the leading tail of the sheet material likely will be positioned close to the tearing segment of the dispenser 10.
- the tearing segment may for example be formed by a tooth-shaped tearing rim on a lower end of a hood 13, 14.
- the control unit of the dispenser 10 may further register the rotational direction of the roll 1 1 during withdrawal of sheet material therefrom. Thereby, the control unit may control the electrical machine to rotate the rotational shaft 15 in the same direction during the automatic feeding of the sheet material. This arrangement assures that the sheet material actually is dispensed upon powering the electrical machine, and not simply wound-up on the roll 1 1 instead.
- the dispenser may be provided with a proximity sensor arrangement for detecting the proximity of user.
- the detected proximity of the user is interpreted by the control unit as a desire to withdraw sheet material from the dispenser 10, and in response thereto, the control unit is configured to control the electrical machine to feed a certain length of the sheet material from the roll 1 1 for simplifying detection and grasping of the leading tail of the sheet material.
- the control unit Upon detecting and grasping the leading tail, the user pulls the sheet material to withdraw a desired amount of sheet material, and during said removal of sheet material, the electrical machine is caused to rotate and produce electrical energy that is stored in the electrical storage system for next occasion of advancement of the leading tail.
- the proximity sensor arrangement may be formed using one or more proximity sensors that are based on one or more proximity sensing technologies, such as capacitive sensing, infrared light emitting/detecting sensing, etc.
- a further improved feeding result may be accomplished by providing the dispenser 20 with roll size sensing means (non-showed), because then the electrical machine 29 may be controlled based also on current fill level of the roll 1 1 .
- the roll size sensing means may be realised by a mechanical and/or electrical sensor that is responsive to the radial size of the roll 1 1 .
- the current roll fill level may be estimated by monitoring the accumulated number of sheet material feeding events for a unique roll 1 1 , and estimating total amount of withdrawn sheet material based on predetermined data relating to average sheet material withdrawal length for each withdrawal occasion.
- the outer surface 21 of the rotational shaft 15 may exhibit a non-cylindrical cross- sectional shape, which is configured to cooperate with a core 17 of a roll 1 1 that exhibits a correspondingly non-cylindrical cross-sectional shape of the inner surface of the roll.
- the outer surface of the rotational shaft 15 may have a rectangular or elliptic cross-sectional shape.
- the rotational shaft engagement means may comprise at least one retractable radial projection 50 arranged on a circumferential outer surface 21 of said rotational shaft 15.
- a retractable radial projection 50 which is displaceable between a projecting position as seen in fig. 5a and 5b, and retracted position as seen in fig. 5c, increases the possible design possibilities of the corresponding engagements means of the core 17 that is configured to be penetrated by the rotational shaft 15.
- the core 17 must no longer be provided with engaging means that extends axially over a certain length of the core 17 because the engagement means of the core 17 does no longer necessarily engage with the engaging means of the rotational shaft 15 also during mounting of the core 17 onto the rotational shaft 15, i.e. during the relative axial displacement of the core 17 and rotational shaft 15.
- the radial projection 50 may be set in the retracted position, in which the radial projection 50 does not extend beyond the outer cylindrical surface 21 of the rotational shaft 15.
- the radial projection 50 may be set in the projecting position, in which the radial projection 50 is configured to rotationally interlock the rotational shaft 15 with the core 17, as illustrated in fig. 5b, where the core 17 with a helical internal groove 19 is indicated using dotted lines.
- the shape and configuration of the radial projection 50 and core 17 are such that the radial projection 50 and core 17 only mutually engage to provide said rotational interlocking at certain relative angular positions.
- the core 17 may be provided with at least one discrete aperture or cavity in the inner cylindrical surface of the core 17, and at least one radial projection 50 of the rotational shaft 15 is configured to engage with said at least one discrete aperture or cavity when said radial projection 50 and said aperture or cavity radially coincide.
- the service personnel that replaces the rolls 1 1 do not need to be concerned with correct and finalised mounting of the roll 1 1 , i.e. such that the rotational shaft 15 rotationally interlocks with the core 17 of the roll 1 1 .
- merely axially pushing the core 17 onto the rotational shaft 15 may be sufficient, and subsequent rotational interlocking may occur automatically upon rotation of the roll 1 1 , at the angular position when the radial projection 50 radially coincides with the aperture or cavity.
- the core 17 comprises one or more axially, straight or helically extending grooves.
- the retractable radial projection 50 is preferably spring loaded towards a projecting position.
- FIG. 5c illustrates how the leaf spring blade 51 , including the radial projection 50, are temporarily depressed to the retracted position due to momentarily lack of any recess in the interior cylindrical surface of the core 17.
- Other spring loading arrangements of the radial projection 50 are possible, such as a helical spring arranged in a radial cavity in the outer cylindrical surface of the rotational shaft 15, or the like.
- the rotational shaft 15 may further be provided with an arrangement for rotationally locking the rotational shaft 15 with the dispenser body upon use of a core 17 that does not exhibit engaging means that correspond to the engagement means of the rotational shaft 15.
- An arrangement for rotationally locking is schematically depicted in fig. 5a, 5b and 5c.
- the leaf spring blade 51 is here configured to temporarily rotationally lock the rotational shaft 15 with the dispenser body upon radial depression of the leaf spring blade 51 a certain length. The rotational locking is realised when the leaf spring 51 is depressed to an extent where a second, free end 57 of the leaf spring 51 engages a stationary member of the dispenser body.
- the stationary member is here formed by an internal stationary rotational shaft 58 that rotationally supports the rotational shaft 15 at end regions of the rotational shaft 15.
- the stationary rotational shaft 58 is provided with engagement means in form of one or more radial projections 59 that may engage with the free end 57 of the leaf spring 51 , such that rotation of the rotational shaft 15 is prevented.
- the free end 57 of the leaf spring 51 may be provided with corresponding engagement means, such as a cavity 60, to simplify rotational locking of the rotational shaft 15 to the internal stationary rotational shaft 58.
- the leaf spring blade 51 is aligned with the longitudinal axis 53 of the rotational shaft 15, and may be arranged with the free end 57 close to a free end 62 of the rotational shaft 15, or close to the abutment collar 23 of the rotational shaft 15.
- the radial projection 61 is preferably spring loaded radially outwardly to automatically return to a projecting position when the complete roll 1 1 has passed the radial projection 61 in an axial direction, i.e. when the radial projection 61 no longer overlaps with the core 17 in a radial direction.
- the radial projection 61 may be provided with a chamfered surface (non-showed) in the axial direction away from the dispenser wall that supports the rotational shaft 15 for automatic displacement of the radial projection 61 to a retracted position upon initial engagement with the core 17. Removal of the core 17 for roll replacement may require manual depression of the radial projection 61 to the retracted position, thereby enabling removal of the core 17.
- the further radial projection 66 suitable exhibits an elongated shape that is provided with an angular orientation that corresponds to the helical angle of the helically extending groove.
- the longitudinal direction of the elongated radial projection 66 may consequently define an angle a to an axial direction 53 of the rotational shaft 15 in the range of about 40° - 85° when the rotational shaft 15 is arranged to receive a core 17 having a helically extending groove or recess 19.
- This arrangement of the further radial projection 66 may of course also apply to other radial engagement projections of the rotational shaft 15.
- radial engagement projections may include conical, cylindrical, polygonal, or the like, with or without chamfering for simplifying potential automatic locking upon penetration of the core 17 by means of spring loaded radial projections 50, 61 , 66.
- At least one retractable radial projection may be mechanically actuated upon pivoting motion of one of said hoods 14, 15 between closed and open positions.
- a mechanical linkage (not showed) that is connected to the radial projection 50, 61 , 66, and which is actuated upon pivoting the hood 13, 14, such that the radial projection 50, 61 , 66 is moved to a retracted position upon pivoting the hood 13, 14 to an open position, and moved to a projecting position upon pivoting the hood 13, 14 to a closed position.
- the rotational shaft 15 and additional rotational shaft 70 may be arranged on a common member 71 that is horizontally slidable a distance d within the dispenser body.
- the common member 71 is shown in the farthest left position in fig. 7, and may be sliding displaced to a farthest right position as indicated by the dotted line. Feeding is controlled such that the outermost roll is emptied first, and feeding is continued using the more central roll.
- the common member 71 is first displaced to the other extreme position, i.e. in fig. 7 to the farthest right position, and a new fully charged roll 1 1 is mounted on the most central rotational shaft 15, 71 .
- This feeding and refilling procedure allows most efficient use of the dispenser inner volume because the dispenser 10 may have the capacity to only accept a new fully charged roll on the most central rotational shaft due to size constraints.
- Roll fill level may for example be determined by registering the radial roll size of each roll within the dispenser 10, and radial roll size may be registered by electrical and/or mechanical sensors, such as proximity sensors, etc.
- Different feeding strategies may be provided, for example feeding of sheet material from the roll having the smallest radial roll size, and upon depletion thereof initiating feeding from the neighbouring roll.
- Roll fill level information may however also be advantageous for controlling electrical operation of the rotational shafts 15, 70, such that desired length of sheet material is advanced by the electrically operated feeding mechanism. This is consequently also interesting for a single roll dispenser.
- the rotational shaft may be applied to the console pointing out of the dispenser away from the wall on which the dispenser is configured to be fastened, as shown in fig. 3 and 7.
- the rotational shaft may be applied on an inner pivoting hood, as shown in fig. 1 and 2.
- the rotational shaft may further according to yet an alternative be applied to an outer hood, thereby eliminating the need for an inner hood, which consequently may be omitted.
- the rotational shaft may further be oriented with a longitudinal axis substantially perpendicular to the plane of the rear wall of the console, or substantially parallel with said plane.
- the energy storage system may comprise flywheel energy storage suitable for temporarily storing kinetic energy, which originates from the user pulling the web of the absorbent sheet material.
- the energy storage system may exhibit a weight that may be translated between at least two different vertical positions corresponding to different potential energy levels, or the energy storage system may be formed by a hydraulic accumulator that may store pressurised hydraulic fluid, and subsequently supply pressurised hydraulic fluid to a hydraulic machine that is rotationally coupled to the rotational shaft for driving thereof.
- said rotational shaft is rotatably mounted to said dispenser body
- said rotational shaft is a separate part from the dispenser body, and that the rotational shaft has been mounted on the dispenser such that rotational shaft may be rotated while the dispenser body is stationary.
- rotationally locking said rotational shaft with said roll used herein means that the roll and the rotational shaft are separate parts, and that they may be interlocked with each other rotationally around a common rotational axis, such that the roll may not be rotated without causing rotation also of the rotational shaft, and vice versa.
- the term “rotationally coupled” used herein means that rotational motion may be transferred from one object to the other object.
