Definitions

  • the invention relates to a device for creating a paving from elements and to a method for creating a paving from elements.
  • Paving elements are being used, coming from a stacked or randomly oriented stock of paving elements, such as paving stones or paving bricks of concrete or clay and tiles or slabs.
  • Such a device for, on a laying surface, creating a herringbone bond from paving bricks coming from a stock, and subsequently picking up said bond from the laying surface and placing said bond in a work, connecting to previously laid bonds.
  • the invention provides a device for creating a bond of paving elements, comprising a frame having a storage container for the paving elements, a laying surface for supporting the bond and means for transporting the paving elements in a main direction of the device from the storage container to the laying surface, wherein the storage container has a discharge side where the paving elements can be discharged to the transporting means, characterised in that the storage container is placed over the transporting means and the discharge side of the storage container is situated at a side thereof that faces away from the laying surface.
  • the device according to the invention can be compact in horizontal (process) direction, as the paving elements are transported below past the storage container to the laying surface.
  • the vertical space over the transporting means is utilised for the stock.
  • use is made of the potential energy, as a result of which when the paving elements are manually placed on or near the transporting means the burden on the workman is low.
  • the device can also be kept compact in the vertical sense when between the storage container and the transporting means a passage space for the paving elements is left open, which has a smallest height which at the most is a few times the height of the treated paving elements.
  • Preferably said smallest height is 1.5 to twice the height of the treated paving elements. This increases the safety.
  • a passage space for the paving elements is left open between the storage container and the transporting means, which passage space can be adjusted as regards height, so that the optimal height for the paving elements in question can at all times be realised.
  • Treating the paving elements in the transition from the stock to the transporting means is enhanced when the transporting means extend in a direction opposite the main direction beyond the discharge side of the storage container.
  • the workman then has room for guiding the bricks and the like downwards and is able to place the bricks with an overview on or near the transporting means.
  • one or more positioning surfaces are provided for one or more paving elements coming from the storage container.
  • the positioning surface may be single or multiple and then be formed by a number of support surfaces, which considered in transverse direction, are spaced apart from each other.
  • the positioning surface may offer a support to one or several series of paving elements that are transverse to the main direction.
  • the positioning surface can be moved, particularly can be pulled away, for discharge of said series to the transporting means.
  • sliders are provided which push the bricks placed on the positioning surface from the positioning surface onto the transporting means.
  • the device is provided with means for detecting the presence of a brick on its support surface in question and giving a signal for it to a control unit, wherein the control unit, depending on the signal received from the detecting means activates means for discharging the brick in question from the positioning surface.
  • the control unit may be provided with a memory for storing the fact of discharging the brick in question, and be adapted for activating the discharge means again depending on receiving signals regarding the brick discharge from other support surfaces, in one embodiment not until said signals have been received for all other support surfaces.
  • a number of magazines can be placed for forming a number of accommodation spaces, each for a series of bricks supporting on each other, wherein the accommodation spaces are open at an upper side for receiving bricks coming from the storage container and are open at a bottom side for discharging bricks to the positioning surface, wherein the magazines preferably are placed to let the bricks therein support on a brick situated on the positioning surface, wherein the accommodation spaces preferably are separated from each other by separation means, such as walls, and/or wherein, preferably, the magazines, as regards location, can be adjusted in transverse direction and/or the magazines can be replaced.
  • the magazines can be detached from each other or formed as one unity
  • a side stop is present for a series of paving elements that are coming from the storage container and that are transverse to the main direction, which side stop preferably can be adjusted in transverse direction. In this way the workman is able to realise the exact desired position of the paving elements coming from the storage container, adjusted to the further process, particularly the bond formation on the laying surface.
  • one or more side stops are present for positioning the bricks coming from the storage container in transverse direction.
  • they can be moved in transverse direction between two positions corresponding with the desired paths of movement of the discharged bricks, should this be necessary particularly when forming a herringbone bond (see for instance figure 6 of EP 1.600.556 ).
  • Said embodiment can advantageously be combined with the embodiment described two paragraphs above, wherein the side stops are not moved by the control unit until the control unit has detected that a brick has been discharged from all support surfaces.
  • the storage container in the main direction, leaves the laying surface exposed, so that the laying surface remains properly reachable for equipment for placing the formed bond towards/in the work.
  • the device may be provided with an end stop for the bond in the making on the laying surface.
  • the end stop is profiled in transverse direction and the profile is adjustable in that direction, so that adjustment to the dimensions of the paving elements is possible, particularly when forming a herringbone bond.
  • the position of the end stop is also adjustable in the main direction, so that the geometric centre of gravity of the formed bond can be adjusted, particularly to the pick-up equipment used.
  • the deployability of the device is increased when the end stop is replaceable by an end stop having a different shape and/or different dimensions, so that adjustment to the desired type and size of paving element, such as paving brick, tile or slab, and their dimensions, and the desired bond, such as herringbone, half-brick or stretcher, can take place at all times.
  • Creating the bond can further be enhanced when the device is provided with a side stop for the bond in the making on the laying surface, preferably on either side. Adjustment to the used paving elements and the desired bond can be facilitated when the position of at least one of the side stops is adjustable in a direction transverse to the main direction and/or in main direction.
  • the transporting means also form the laying surface.
  • the paving elements are then touched as little as possible in the entire process.

  • the drive for the outrigger can as a result be kept simple.
  • the suspension itself is provided with means for driving the suspension along the outrigger.
  • Operation means can in that case be provided on the framework for operating the drive means of the suspension.
  • the outrigger can be retracted by operating the drive at the suspension.
  • the outrigger is provided with a rack and the suspension is provided with a pinion cooperating therewith.
  • the support can be rotatable on the frame about a substantially vertical centre line, preferably by means of a motor on the device.
  • the pick-up device present for picking up a completed bond from the laying surface and transferring it into the work, comprises a framework that is provided with pick-up means, such as suction cups, for the paving elements in the completed bond and furthermore is provided with means for adjusting the mutual distance of the pick-up means.
  • pick-up means such as suction cups
  • the storage container is provided with means for supplying the elements to the discharge side, wherein the supply means are active in a direction opposite the main direction.
