Definitions

  • the invention relates to a method and apparatus for transfering layers of paving bricks from a uniformly oriented initial pattern to a herringbone laying pattern.
  • Such a method and apparatus are known from the Dutch patent application 86.00820.
  • rows of bricks are fed, by layer and by transverse row, from a stack of a number of layers of bricks positioned on the upstream side of the apparatus across a vibrating and slanting transport plane, whilst enlarging their mutual transverse distance, to a converting apparatus, where they are converted by means of sliding chutes to a slanting position of 45° with regard to the feed direction.
  • the bricks are transported further up to a transversely placed framing which can be adjusted to a mean herringbone size of the brick pattern.
  • the converted bricks particularly the first rows of the module of bricks in herrringbone pattern which is to be formed, can loose their orientation during displacement from the converting means to abutment against the stationary framing or against the last row of bricks placed up against it, and this in such a way that corrections have to be carried out manually. During this, the converting process has to be stopped temporarily, which means loss of efficiency.
  • An object of the invention is to improve this, which is achieved with the help of the measures indicated in claim 1 (method) and claim 7 (apparatus).
  • guide jig means or confining means are provided, which laterally check the bricks which are in a herringbone pattern.
  • These guide jig means which can at the same time serve as guide for the end jig during the displacement thereof, are also adjustable to the processed bricks, that is to a distance of (n1.L+B). 1 ⁇ 2 ⁇ 2, in which n1 is the number of bricks per row in transverse direction, L the length of the brick, including leeway/tolerance for smoothing out irregularities such as small loose stones, and B the width of the brick, including aforesaid margin. These L and B are indicated below as the practical length and width.
  • the guide jigs are adjusted at sight, for example whilst making the first module. Then is is ensured that the adjustment is also correct for the brick actually treated. Within a determined circumference, which thus can be adjusted per situation, on average and on balance each brick will be laid in a allotted rectangular surface area, which corresponds to the practical brick size.
  • Each produced module therefore has an equal circumference size (width, length) with a same number of bricks.
  • the formed module placing layer can be made from rectangular bricks of any size, whether the bricks have already been used or are new. This is a considerable advantage over an existing method according to which multi-layered packs of bricks in herringbone pattern are delivered. Only bricks of which the length is twice the width are suited for packs of that kind.
  • the placing layer can then also be held to be concentrated in the centre of gravity surface, onto which centre the take-up means can be controlled.
  • the take-up means can be controlled.
  • the latter can be guided to the correct place with the help of suitable orientation means which indicate the centre of gravity in the paving work.
  • the orientation or positioning means can comprise laser apparatuses, but can in their simplest form be realized in the form of a jig to be placed on the work.
  • the take-up means are provided with one or more suction cups, for each brick at least one.
  • a suction cup of that kind is described.
  • the suction cup then being provided with a rubber casing, which is oval of elliptical in cross section.
  • Converting the bricks which are still uniformly oriented in series of slantingly directed bricks in particular oriented alternately at an angle of 45° can take place in a variety of ways. According to the Dutch patent application 86.00820 this can be achieved with the help of sliding chutes which are alternately set in opposite directions at an angle of 45° vis-à-vis the supply line, or by supplying the bricks from two packs of bricks arranged laterally at an angle of 45° vis-à-vis the laying jig.
  • the bricks are offered in a pattern, in which the one half of the bricks lies approximately half a length in front of the second row of intermediate bricks, to a so-called lazy-tongs (Neurenberger link or mechanism) operating from above which is provided with suction cups which are lowered on the bricks.
  • the two rows of bricks are then brought on different levels vis-à-vis one another and subsequently converted by the action of the tongs, the one row of bricks, as seen in the horizontal plane, being turned clockwise and the other row of bricks being turned anticlockwise. Then the bricks are brought back to the same level and lowered again, to be subsequently removed to the placing layer to be formed.
  • a drawback of this construction is that it is rather complicated.
  • a method for mechanically laying bricks in a herringbone pattern and an apparatus for that purpose are known from the Dutch patent application 86.02633, where use is made of a herringbone jig for converting rows of bricks of which the longitudinal sides are placed adjacent one another to a herringbone pattern, which herringbone jig can take on a transverse receiving position in which the oncoming row of bricks can be received in a way shifted in transport direction vis-à-vis one another and which jig can then be turned alternately to the one side and to the other side to turn the bricks to a position in which they form a row which is again perpendicular to the direction of advance and are adapted for connecting to an already formed herringbone pattern.
  • the converting means are adapted to engage the bricks for turning them to a herringbone orientation whilst at least substantially maintaining the mutual centre-to-centre distance in transverse direction of the bricks.
  • the converting means comprise drive means for drivingly engaging the bricks in direction of transport at a location situated on a first longitudinal half of these bricks in order to accelerate that first longitudinal half with regard to the second longitudinal half and furthermore bearing means for creating a point of rotation for the second longitudinal half of those bricks by engagement of a location on said second half.
  • the bricks are thus converted to a herringbone orientation by the drive means, about the turning point located on the other side of the brick concerned.
  • the invention thus also relates to a method for converting a row of parallel paving bricks arranged next to one another to a row of bricks arranged next to one another in herringbone fashion, wherein the bricks are turned with their longitudinal axis through an angle of 45° by engaging the bricks during the advancement of these bricks across a supporting transport plane in order to accelerate their corresponding first longitudinal half of these bricks with regard to the adjacent second longitudinal half thereof, whilst having those bricks turn through an angle of 45° about a contact point between the second longitudinal half and a stationary bearing point.
  • the resultant of the forces in transport direction exerted on the first longitudinal half is greater than the resultant for the second longitudinal half (which resultant can even be zero), so that a brick turning moment is created.
  • the drive means comprise driven rollers which are arranged to engage the underside of the bricks.
  • the drive means are thus arranged at a place without forming an obstacle and engage the underside of the first longitudinal half of the bricks to accelerate the latter in relation to the other longitudinal half.
  • the drive rollers are preferably placed so as to project in a recess in the support plane in order to engage the first longitudinal half of the bricks, while the second longitudinal half is supported by the supporting plane.
  • the drive rollers have a first portion which is provided with a rough surface and a second portion which is provided with a smooth surface, wherein the first portion and the second portion are placed in axial direction next to one another to engage the first and the second longitudinal half of the brick, respectively.
  • the first portion which engages the first longitudinal half of the bricks has a larger diameter than the second portion, which remains at a clear distance from at least a part of the underside of the second longitudinal half.
  • the bearing means are preferably formed by extended longitudinal guides extending in transport direction to beyond the drive rollers, which are interspaced in transverse directions at distances of approximately two rows of bricks and alternate in transverse direction with shorter longitudinal guides, which are interspaced in transverse direction at distances of approximately two rows of bricks, wherein the drive rollers, as seen in transport direction, are arranged downstream from the ends of the short longitudinal guides and substantially upstream from the end of the extended longitudinal guides, wherein the first transport means comprise means for alternately offering the converting means transverse series of bricks which, as seen in transverse direction, are located on 2n and 2n-1 positions, respectively.
  • transverse series of bricks are offered in turn to the drive rollers, the alternately offered transverse series respectively finding their rotational points at the end of the extended longitudinal guides.
  • the invention concernded can be simplified by allowing the drive rollers to be arranged in two adjacent brick transport paths each time. These drive rollers can be in line in transverse direction, and then be rotated by one single drive shaft.
  • the converting means comprise turning means which are placed so as to engage the side of the bricks at a distance from the horizontal middle thereof, the drive means for the converting means displacing them in transverse direction to turn the bricks in their horizontal plane after engagement thereof.
  • a preferred embodiment of this apparatus is described in claim 15.
  • the same pusher rod can the one time convert a brick present on the right hand side thereof to allow it to be turned in an anti-clockwise direction and then be pressed against a following brick situated on the left hand side thereof, to convert it whilst turning it in a clockwise direction.
  • the end jig or the last laid herringbone row, respectively is held at such a distance in working direction from the pusher rods that the brick to be converted arrives with one front vertical corner rib against the end jig or that row of bricks already laid, to form a point of rotation during turning of the brick.
  • the end jig thus attains an additional function.
  • the lazy tongs structure is in principal retained, but instead of suction cups which retain the bricks in a vertical sense, use is made of preferably U-shaped brick receiving openings such as described in claim 16.
  • the integrated and movable apparatus comprises a frame 2, which is movable by means of wheels 3 and can be hooked with a coupling part 4 to a lorry, for example.
  • a platform 5 On the right hand or supply side of the apparatus 1 there is a platform 5, on which a stack of bricks S is put.
  • the platform 5 can be moved up and down along a guide 6. This takes place with the help of a motor, not shown, which can be operated with the help of an operable and adjustable control apparatus 21.
  • An outrigger 7 attached to the frame 2 extends, as seen in the drawing, to the right and above the stack S.
  • a slide 8 is arranged, which is movable back and forth in a driven manner along the outrigger 7 in the directions of the arrow B.
  • the vibrating plate 10' can be extended on the upstream side for defining a supply table while the pack of bricks S is placed ahead of that on a jack-up platform.
  • a separate gripping tool comprising a front clamping strip of a rear clamping strip, the upper layer of bricks is then, whilst being clamped, slid onto the supply table, until all the bricks are supported by it.
  • a fixed lateral guide and a lateral guide which is transversely adjustable ensure that the supplied layer of bricks is placed exactly in front of the entrances to the guide paths which are to be discussed below. Then the front clamping strip, which also ensured that the preceding group of bricks moved up, is lifted up and the layer of bricks is then pushed along to some extent with the rear clamping strip.
  • the vibrating plate 10' also terminates at the downstream end of the guide plates 9 and a few centimetres (for example 2 cm) above that there is the upstream end of the following vibration plate 10'', which forms the support surface at the converting and laying parts of the apparatus 1.
  • the upstream end of vibrating plate 10'' and the downstream end of vibrating plate 10' preferably engage in a finger or tooth fashion into one another as seen in vertical projection, whilst leaving intermediate small vertical passages clear for pusher rods 12 which are arranged just beneath the vibrating plate 10' (see figure 1A) and which are movable up and down (directions D).
  • the upstream end of the vibrating plate 10'' forms a shoulder 11, against which the bricks delivered by brick supplied through brick paths come to rest, to then, on command, be tipped up by the upward movement of selected pusher rods, so as to arrive with the lower front edge on the vibrating plate 10'' and to be subsequently transported further on it under the influence of the vibrations.
  • a converting device Downstream from the shoulder 11 a converting device is arranged, which is attached by means of posts 15 to the frame 1. This converting device will be discussed below in detail.

  • the end jig 23 and the lateral guides 22 are selected and/or adjusted to the practical brick size and the dimensions of the desired module.
  • a taking-up apparatus 24 is arranged on the discharge end of the apparatus 1.
  • the latter is attached by means of posts 28 tot the frame 2 and provided with an articulated working arm 27, at the end of which a frame 25 is attached, to which a series of suction cups 26 is attached.
  • the frame 25 and thus the suction cups 26 are movable up and down in the directions G, to be brought into engagement with the bricks.
  • the working arm 27 is swivellable in the horizontal to displace the frame 25 with suction cups 26 and bricks sucked firmly by it to the left in the direction H in order to deliver the bricks into the paving work (not shown).
  • first of all stack S of bricks is delivered to the platform 5 by a fork-lift truck.
  • the platform 5 is then adjusted along guide 6 to such a height that the bottom side of the upper layer of bricks is at level with the surface of the vibrating plane 10'.
  • the vibrating plane 10' is made to vibrate and the slide 8 is moved to the left, in the course of which the slide 8 moves the upper layer of bricks to the left onto the vibrating plane 10'.

  • the pusher rods 12 for the even rows b, d etc. have been lifted for a while.
  • a brick has been let through.
  • These bricks are received by the end jig 23 provided with a zigzag shaped end plane.
  • This end jig 23 is adjustable or is selected for the size of the brick to be handled.
  • the end jig 23 is held at a place such that for a moment the bricks b, d, etc. are restrained with their vertical left front rib.
  • the end jig is displaced along a distance of 1 ⁇ 2 ⁇ 2 the (practical) width, across the vibrating plane and guided by the guides 22.
  • the bricks a, c, e etc. then come in a position which is comparable to that of the bricks b, d, etc., in figure 2B, but now rest with their right hand front rib against a head face of those bricks b, d, etc. instead of against the contact plane of the end jig 23.
  • the converting apparatus 14 is operated once more, but now in such a way that the cylinder 16 is moved vis-à-vis the piston rods 17 in the direction E2.
  • the pusher bars 18 are then pressed against the left side faces of the bricks a, c, e etc. as a result of which said bricks, as seen on paper, are turned to the left, during which movement the right hand front rib which makes contact will slide along the head face of the bricks b, d etc. and then along the contact plane of the end jig 23.
  • the head faces of the bricks a, c, e, etc. have arrived at the contact plane of the end jig 23, the first herringbone patterned row is completely ready.

  • a suchlike point of orientation can be coupled in a way known to the expert with aligning means which have been installed for that purpose in the paving work and which measure the average position of modules previously placed in the work. Controlled by signals to be delivered by the aligning means, the laying means 24 will then be able to place the frame 25 and the suction cups 26 in exactly the correct position, after which the suction cups 26 are deactivated and the bricks can be left behind in the sand bed in the paving work.
