Definitions

  • the invention relates to a device for lifting a layer of stones, according to the preamble of claim 1.
  • the invention also relates to a method for lifting a layer of bricks according to the preamble of claim 21.
  • Stones for example covering elements, facade elements, sand-lime bricks, concrete blocks, bricks or brick clinker, natural stones and the like, in particular concrete paving stones, are generally produced in layers, further treated or stored and stored. The transport from the factory to the customer is usually carried out by stacking the stones one above the other in layers.
  • the layers can consist continuously of stones of different sizes which, in addition, can have different contours, for example square, rectangular, polygonal or round.
  • the individual stone layers can also vary in their overall size and be formed in themselves from different stone formats, so that the proportion of "Leerabsaugung", ie the area in which the suction port of the vacuum device hits no stone is disproportionately high.
  • solutions outside the stone production which provide a suction plate with, for example, 100 or 200 micro-openings, each micro-opening having a valve. About a corresponding electronics can be opened through the valves, the smallest openings, which is associated with an element to be lifted. The unneeded micro-openings are closed or switched off.
  • solutions which may work in other industries, however, can not be used in the field of stone production or are subject to a high susceptibility.
  • stone production especially when the stones are reworked to lose their artificial appearance, a large amount of dust is created, causing valves and thin lines to clog quickly and therefore to be maintenance-intensive. In order If they can be used in stone production, they must be robust and not susceptible to the environmental conditions associated with stone production.
  • the present invention is therefore an object of the invention to provide a device and a method for lifting different layers of stones, especially small-sized concrete paving stones in a simple and cost-effective manner.
  • the stencil element produces a pattern of closed and open suction regions adapted to the respective layer of stones to be lifted, the suction power of the vacuum device being substantially concentrated on the stone surfaces.
  • closed areas are formed by the template element, so that no suction power is lost. In this way, gaps between the stones and possibly also the edge region of the stones can be closed accordingly.
  • it is thus achieved that even small-sized bricks of a layer of bricks can be reliably lifted. Any existing between the stones distance can be maintained, since a manual or hydraulic pushing together of the stones is not necessary.
  • a corresponding template element can be supplied in each case depending on the position of stones to be lifted of the suction opening, which in turn generates a pattern of closed and open suction regions, which is essentially adapted to the position of stones to be lifted and the suction power accordingly concentrated on the stone surfaces.
  • a single vacuum device is thus sufficient to reliably lift a variety of different layers of stones, both in terms of their overall layer size and in terms of size and circumference of the individual stones. Even stones or layers of stones with special formats can be easily raised.
  • the template elements can be continuously adapted to the different layers of stones. The production process is thus not disturbed.
  • the cycle speed and a high production rate is of particular importance. Therefore, it is advantageous to change the template elements as quickly as possible. It is advantageous if several template elements are wound on a unwinding and winding device.
  • the unwinding and winding device can cooperate with the vacuum device in such a way that the suction opening can in each case be fed with the template elements corresponding to the position of stones to be lifted.
  • the unwinding and winding device has at each of two opposite ends of the suction opening a roller for unwinding or winding up the template elements.
  • the rollers may be provided directly on the vacuum device, on a lifting and transporting device connected to the vacuum device, or on a separate holding device.
  • the template elements allows a particularly fast and reliable changing of the template elements, whereby a pattern corresponding to the position to be lifted can be created on closed and open suction areas. After discontinuing a stone layer and before re-recording another stone layer can already be supplied, for example, by a corresponding winding mechanism already the new template element. Changing the template element thus requires no additional time.
  • any material which can be provided with corresponding passage openings for forming the open suction regions and is suitable for winding onto a roll or the like is suitable as the template element for the unwinding and winding device.
  • films preferably plastic films, since they are correspondingly thin and yet can be designed tear-resistant.
  • the template elements can also be formed from sponge rubber, preferably with fabric inserts. It is also possible to provide the sponge rubber additionally with an airtight film.
  • the template element is merely formed from a foil, it has proved to be advantageous to provide the underside of the suction opening with a yielding surface which adapts to the stone surface.
  • foam rubber can be used.
  • a resilient surface on the underside of the suction opening has the advantage that unevenness in the stone surface can be compensated for and the suction opening can be flush with the stone surfaces.
  • the sponge rubber also allows a good seal.
  • the individual template elements are releasably connected to each other.
  • a detachable connection of the individual template elements of the unwinding and winding device has the advantage that when a template element is damaged, it can be detached and replaced by a new template element. An exchange of the entire unwinding and winding device is therefore not necessary.
  • the template elements are plate-shaped, for example made of plastic or metal, are formed.
  • the suction opening can be provided, for example, with a slot for receiving the plate-shaped template elements.
  • the plate-shaped template elements are magnetically connected to the suction opening.
  • the vacuum device is provided with an electromagnet, which is activated after supplying the corresponding magnetically attractable template element and deactivated again for changing the template element.
  • the template elements can be stored in a quick-change device, which is preferably positioned spatially close to the vacuum device. From the field of tool changing devices, a variety of solutions are known in order to realize a fast and reliable replacement of the template elements. For example, this could also be done as usual with CD changers.
  • the Schablo each have an identification key or code.
  • the code (for example a barcode) can preferably be recognized or read by a sensor, so that the suction opening is supplied with the correspondingly provided template element either by additional automatic detection of the next layer of stones to be lifted or by manual operation.
  • suction opening is provided with a grid. This provides for the template elements a suitable system without significantly affecting the suction power.
  • Figure 1 is a schematic representation of the device according to the invention from the side with a take-off and winding device before lifting a layer of stones.
  • Fig. 2 is a bottom view of a template element
  • Fig. 3 is a schematic diagram of Figure 1, wherein a layer of stones is sucked or raised.
  • FIG. 4 is a view of the device according to the invention in the direction of arrow IV of FIG. 3; and Fig. 5 is a constructive to FIG. 1 alternative embodiment of the device according to the invention, wherein the template element is plate-shaped.
  • any stones for example covering elements, facade elements, sand-lime bricks, brick or brick clinker or natural stones, be raised independently of their material properties.
