Definitions

  • the present invention relates to an apparatus for rolling a carpet, a rug or a door mat, e.g. a cut pile door mat, where the apparatus at least comprises:
  • the present invention also relates to a method for rolling a carpet, a rug, or a door mat, e.g. a cut pile door mat, using an apparatus as described above, where the method comprises the steps of:
  • carpet rollers or mat rollers are often used to automatically roll carpets, mats, and rugs into a compact configuration for easy storage and handling. Such rollers may also be used in industrial laundries to roll blankets, duvets, towels and the like into a compact configuration.
  • the mat or carpet is transferred to the carpet or mat roller typically after the cleaning and drying process where the roller mechanism rolls it into a compact configuration. This is typically done by placing the mat or carpet on a conveyor system which then is fed into the roller mechanism. The rolled up mat or carpet is then transferred onto an unloading station or another conveyor system and finally transferred to a storage unit for storage.
  • the mats are typically fed into the roller mechanism by using a single inlet conveyor having a single conveyor belt extending beyond the width or length of the mat.
  • the mat is normally placed on the conveyor in the same perpendicular direction relative to the roller mechanism regardless of the pile direction of the mat.
  • rotating roller elements roll the mat into a compact spiral shaped configuration where the top surface is brought into contact with the bottom surface.
  • the direction of the piles in the mats may differ from the rolling direction causing the mat to shift and move sideways during the rolling process.
  • This causes the mat to form a crooked compact configuration where the edges are not aligned in the same perpendicular plane relative to the longitudinal direction of the rolled up mat, but are instead biased towards the mat or away from the mat.
  • This may require that the mat has to be unrolled and rolled up again which increases the handling of the mat.
  • This also makes the edges more susceptible to damage during handling and storage and increases the risk that the edges form a bend or fold when the mat is unrolled.
  • Another object of the invention is to provide an apparatus that is able to adjust the direction of the mat relative to the pile direction so that the edges are aligned in the same plane during the rolling process.
  • a further object of the invention is to provide a method for rolling up a mat that allows the edges of the mat to be aligned during the rolling process in a simple manner.
  • the invention relates to an apparatus for rolling a carpet, a rug, or a door mat, characterised in that:
  • the term "mat” is defined as any type of a flat, rollable piece, such as door or floor mats, rugs, or carpets, having a top surface or nap comprising a plurality of piles or forming a pile structure.
  • the piles may be loop piles, uncut or cut piles, tufted piles, or another type of pile.
  • the "direction of the piles" or the “pile direction” is to be understood as terms indicating the impact of the mats tendency to become rolled into a crooked configuration as mentioned above.
  • the mat can be arranged/rearranged in a suitable manner prior to being rolled in order to form a uniform rolled mat.
  • the mats may be placed on the inlet conveyor with the top or bottom surface facing the inlet conveyor manually or in a more automated manner.
  • the sensing unit may be positioned above or below the inlet conveyor depending on the orientation of the mats. By placing the mat with the top surface facing away from the inlet conveyor allows for a quality check of the mat at the start of the process.
  • the inlet conveyor may form part of the roller unit or part of a conveyor system coupled to the roller unit. By rolling the mat with the top surface facing outwards allows the mat in a flat configuration to form a better contact with the surface of the floor.
  • control unit may be coupled to a display unit for displaying the pile direction of the mat to an operator located at the roller unit. This allows the operator to manually adjust the position of the mat relative to the pile direction when placing the mat on the inlet conveyor.
  • the pile direction may be used to determine the angle at which the mat is positioned relative to the roller mechanism. By placing the mat in an angled position relative to the roller mechanism, the shift and sideways movement of the mat due to the piles are counteracted.
  • the apparatus comprises at least a second inlet conveyor arranged relative to the first conveyor in the same plane for feeding the mat into the roller mechanism, wherein the second inlet conveyor is configured to be driven at a speed that differs from the speed or is the same as the speed (V 1 ), at which the first inlet conveyor is driven, wherein the speed of at least one of the inlet conveyors is determined based on the pile direction.
  • a second inlet conveyor can advantageously be arranged in parallel with the first inlet conveyor as will be seen in fig. 4 and 5 .
  • the apparatus may comprise two, three, four, five or more inlet conveyors arranged relative to each other in the same plane.
  • the inlet conveyors may be placed side-by-side and may be spaced apart so that the sensing unit may be positioned in or over the gap formed between two inlet conveyors.
  • the inlet conveyors may be coupled to the same drive unit via individual gear systems or coupled to their own drive unit where the control unit may control each drive unit and/or gear system.
  • the drive unit(s) may be an electrical drive unit, such as an electrical motor, or a pneumatic or hydraulic drive unit.
  • the inlet conveyors may comprise a conveyor belt or an endless chain on which the mat may be placed where at least one drive wheel drives the belt or chain.
  • the inlet conveyors together form a common feeding end at which the mat may be fed into the apparatus.
  • the inlet conveyors may be configured to be driven at the same speed or at different speeds determined according to the pile direction. This allows the position of the mat to be adjusted automatically by regulating/adjusting the speed of one or more of the inlet conveyors.
  • the sensing unit at least comprises a moveable element configured to be brought into contact with the top surface of the mat, wherein the element is configured to be activated and moved by the piles.
  • the moveable element may be an elongated element having a free end shaped to contact and slide along the top surface, as the mat is moved past the sensing unit.
  • the element may at the other end be coupled to a rotation point or axle allowing the element to rotate or pivot relative to that rotation point or axle.
  • the element may be a free hanging element, such as a spherical, elliptical or another three-dimensional shaped element, suspended from a wire, string, or rope.
  • the element may be configured to move freely relative to the mat in two or more directions or limited to move in one or two directions relative to the mat, e.g. perpendicular and/or parallel to the transport direction of the inlet conveyors.
  • the movement of the element may be defined by the direction of the piles. This allows the pile direction to be sensed mechanically in a simple manner.
  • the sensing unit further comprises at least one sensor arranged relative to the moveable element, wherein the sensor is configured to sense the movement of the element.
  • the moveable element may be coupled to an electrical or optical sensor for transforming the mechanical movement into an electrical signal.
  • the sensor may be a position/distance sensor or encoder configured to measure the angular or linear movement of the element.
  • the sensor may be an electrical sensor configured to measure the movement as a change in the resistance, current or voltage of the sensor.
  • the sensor may be an optical sensor or receiver configured to measure a reflected signal of the moveable element.
  • An energy source or transmitter may be used to transmit a signal or beam, e.g. an IR-light beam or a laser beam, onto the element which is then picked up by the optical sensor or receiver. Any other type of sensor may be used to sense the movement of the element.
  • the sensor may be positioned over the element and face the top surface of the mat, or it may be placed in the same plane as the element facing one of the sides of the element.
  • a second sensor may be located at the other side and face that side. This allows the control unit to determine the pile direction based on the sensed data and adjust the speeds of the inlet conveyors accordingly.
  • the sensing unit comprises at least an image capturing device, where the image capturing device is coupled to an image analysis module in the control unit for determining the pile direction based on the captured image data.
  • a camera or image scanner may be used to determine the pile direction of the mat.
  • the camera may be positioned at a distance from the inlet conveyor and face the top surface of the mat.
  • a light source may be used to enhance the contours of the mat/piles and/or to increase the amount of reflected light.
  • the pile direction is determined based on the captured image data.
  • the type of camera is selected so that it has a pixel resolution and/or colour resolution that allows it to recognise the piles in the image data. This allows the pile direction to be determined wirelessly.
  • the camera or one or more image sensors may alternatively be used to capture the movement of the moveable element.
  • the roller mechanism at least comprises two sets of rotatable roller elements arranged relative to each other for rolling the mat into a compact configuration, where the two sets of roller elements are driven by at least one second drive unit and configured to rotate in the same direction.
  • the roller mechanism may comprise three, four, five, or more sets of roller elements which are arranged relative to each other, e.g. according to an arc or elliptical segment.
  • Each set may comprise one or more roller elements distributed along a rotating axle for better guidance of the mat during the rolling process.
  • the sets may form an opening through which the mat is transferred from the unloading end of the inlet conveyor and into the roller mechanism.
  • the roller elements may be a wheel, e.g. of rubber or covered with a layer of rubber, or a disk shaped arrangement of radial extending brushes.
  • Each set of roller elements may be driven by the same drive unit or individual drive units, such as an electrical drive unit in the form of a motor with an optional gear system. This provides a simple and compact roller mechanism that allows the size of the roller unit to be reduced. This also allows a damaged set of roller elements to be easily and quickly replaced.
  • the opening of the roller mechanism may be positioned adjacent to the unloading end of inlet conveyors in an inverted C-shaped configuration. This allows the mat to be transferred directly into the roller mechanism.
  • the inlet conveyors may be placed in an angle position where the unloading end is located above the opening of the roller mechanism.
  • the roller mechanism may be placed in a substantially U-shaped configuration. This allows the mat to be more or less dropped into the roller mechanism, and reduces the total length of the roller unit or allows the length of the inlet conveyor to be increased while maintaining the total length of the roller unit.
  • At least one of the sets of roller elements may be configured to be moved, e.g. lowered, relative to other sets for unloading the rolled up mat onto an unloading station or another conveyor system.
  • the roller mechanism at least comprises one roller conveyor or two roller conveyors arranged relative to the inlet conveyor for rolling the mat into a compact configuration, wherein the roller conveyor or the roller conveyors are configured to transport the mat in at least a second direction relative to the first direction of the inlet conveyor.
  • One or two of the sets of roller elements may be replaced with a roller conveyor arranged relative to the other two sets of roller elements.
  • the roller conveyor may be configured to transport the mat from the inlet conveyor towards the roller elements.
  • the roller conveyor may comprise a conveyor belt or an endless chain on which the mat may be placed where at least one drive wheel drives the belt or chain.
  • the roller conveyor may be coupled to a pivot point located at the opposite end of the sets of roller elements where the roller conveyor may be pivoted relative to that pivot point for unloading the mat.
  • the roller conveyor or the sets of roller elements may be configured to be raised or lowered relative to the sets of roller elements or roller conveyor for unloading the mat. This allows the mat to be rolled up using a combination of conveyors and rotating roller elements.
  • all sets of roller elements may be replaced by roller conveyors.
  • two, three, or more roller conveyors may be positioned relative to each other according to arc, elliptical or rectangular segment.
  • the rolled up mat may be unloaded by pivoting the roller conveyor, as described above. This allows the mat to be rolled up using an arrangement of roller conveyors.
  • the roller mechanism further comprises one or more guiding means, e.g. a guiding plate or rod, for guiding the mat into the compact configuration, where the guiding means are arranged relative to the sets of roller elements or the roller conveyors.
  • one or more guiding means e.g. a guiding plate or rod
  • One or more of the sets of roller elements and/or roller conveyors may be omitted and replaced by one or more guiding means.
  • the guiding means may be a plate or rod having a curved or straight shape configured to guide the mat into the desired direction.
  • the plates or rods may be positioned so that they extend outwards from the surface of the roller elements or roller conveyor. This allows the number of moving parts in the roller mechanism to be reduced.
  • the invention relates to a method for rolling a carpet, a rug, or a door mat, characterised in that:
  • a sensing unit facing the top surface of the mat may sense the pile direction which may be displayed on a display located in the roller unit. An operator may then manually adjust the position of the mat according to the displayed pile direction, or according to an indicator dependent on the sensed pile direction, so that the mat is placed in an angled position more or less corresponding to the pile direction.
  • the pile direction or a value indicating the pile direction, is within a certain narrow threshold value, it can mean that the longitudinal direction of the mat, and thus the direction in which the mat is fed into the roller mechanism, is ok and the position of the mat may not be adjusted. If the pile direction, or a value indicating the pile direction, is above or below a certain threshold value, the mat may be placed in an angled position, positive or negative, relative to the longitudinal direction. Then the mat may be turned, clockwise or anticlockwise, by an amount equal to the sensed value so that the longitudinal direction of the mat is corrected to be substantially nonparallel with the inlet conveyor.
  • the mat is fed onto at least two inlet conveyors where the speed of at least one of the inlet conveyors is determined according to the pile direction.
  • Said two inlet conveyors can be arranged in parallel and side by side in the same plane.
  • the change in the speed for each inlet conveyor may be determined as function of the pile direction and optionally the number of the inlet conveyors.
  • One of the inlet conveyors e.g. the rightmost or leftmost, may be used as reference where the speeds of the other inlet conveyors are increased or decreased by a predetermined amount.
  • the inlet conveyors may be divided into two groups where the speed of one group, e.g. the left half, is increased and the speed of the other group, e.g. the right half, is reduced, or vice versa. This allows the control unit to determine the pile direction and then adjust the speed of the inlet conveyors for placing the mat in a proper angular position relative to the roller mechanism.
  • At least one sensing unit senses the pile direction by directly contacting the top surface of the mat and/or by wirelessly sensing, and a control unit determines the pile direction based on the sensed data.
  • the pile direction may be sensed mechanically by using a moveable element contacting the top surface as the mat passes by.
  • One or more sensors coupled directly to the element or arranged in the same plane relative to the element may sense the movement of the element and transforms the movement into an electrical signal for the control unit. This provides a simple and easy way of detecting the pile direction of the mat.
  • the pile direction may additionally or alternatively be sensed by using a camera or an image scanner where the captured image data is analysed in the control unit by an image analysis unit.
  • This unit determines the pile direction based on the image data and transmits it to the control unit. This may be done by extracting one or more parameters from the image data and then compare these parameters to one or more sets of reference parameters or patterns. The data are then evaluated in order to determine the direction of the piles. This allows the pile direction to be determined wirelessly, i.e. without contacting the mat.
  • the mat is rolled into the compact configuration by passing the mat by at least two sets of roller elements and/or one or more roller conveyors.
  • the roller mechanism may comprise at least three or four sets of roller elements rotating in the same direction where the sets form an open inner area configured to receive the mat. Each set guides the mat into a new direction so that the mat is rolled into a spiral shaped compact configuration where the top surface contacts with the bottom surface, or vice versa. This provides a simple and compact way of rolling the mats.
  • the mat may be transferred onto two or more roller conveyors arranged to form an inner open area configured to receive the mat. Each roller conveyor may transport or guide the mat into a new direction so that the mat is rolled into the compact configuration. This provides another way of rolling the mat.
  • One or more guiding means may be used together with the set of roller elements and/or roller conveyor to guide the mat into the compact configuration. This allows the mat to be rolled up by using a reduced number of moveable parts.
  • the roller unit may comprise two or more inlet conveyors coupled to the same drive unit or individual drive units where the control unit controls each drive unit.
  • the control unit may be configured to adjust the speed of one or both inlet conveyors based on a control signal indicating the pile direction of a passing mat.
  • the control unit may receive the control signal from an external sensing unit located at an earlier stage in the process line.
  • the pile direction may be displayed to the operator which is able via a user interface, e.g. a touch-sensitive screen or a rotatable knob, to adjust the pile direction, or even input the desired pile direction.
  • Fig. 1 shows an exemplary embodiment of a mat 1 in flat configuration.
  • the mat 1 may comprise a base element 2 having a bottom surface 3 configured to lie against a floor in a building or a transport unit.

  • Fig. 2 shows the mat 1 in a compact configuration after a conventional rolling process.
  • the pile direction 6 of the piles 4 may cause the mat 1 to move sideways in the same direction as the piles 4. This causes the edges 7 of the mat 1 to be misaligned so that they are biased out of the vertical plane 8 defined by the edges of the innermost loop of the compact configuration.
  • Fig. 3 shows the mat 1 in the compact configuration seen from one end.
  • the mat 1 may be orientated with the top surface 5 facing outwards.
