Definitions

  • the usual field of application for this invention is in workshops which, generally working on behalf of third parties, perform post-firing operations on ceramic tiles. These operations include cutting, milling, etching and so on.
  • the tiles are delivered from the ceramics factories in packs, generally packaged using cardboard wrapping.
  • the packages typically have a cardboard border protecting the comers but leave the central bottom and top surfaces free.
  • the packages In order for them to be sent on to work operations, the packages have to be opened once the tile packs have been removed from the pallets.
  • the present invention automates the above-described operation, thus eliminating the drawbacks due to manual operations, by means of the device according to claim 1.
  • An advantage of the device is that it can easily be inserted in normal tile-working lines.
  • a further advantage of the device is that it can operate on tile packs of any size.
  • a further advantage of the device of the invention is that it enables a rapid and efficient disposal of the cardboard packaging after it has been removed from the tile packs.
  • the device of the invention is used for opening packs 10 of tiles 9 which are packaged with a border 10a, normally made of cardboard, which surrounds the edges of the tile pack, leaving the central parts 10c of the bottom and top surfaces of the pack free.
  • the device is for freeing the tiles of their packaging as they arrive from the ceramics factories so that they can be sent on to work stations.
  • the packs are normally on pallets, and contain several rows of tiles. Usually the packs are composed of single rows but sometimes the tiles are so much narrower in one direction than in another that they are in danger of falling over, and are therefore stacked in series of two using straps or the like.
  • the packs, or groups of packs are removed from the pallets either manually or, as illustrated in figure 1, by machine 13, and are arranged on a rest plane 5 provided on the device of the invention.
  • the rest plane 5 for reasons which will better emerge hereinafter, is a conveyor equipped with a pair of parallel belts 5; the packs of tiles are taken onwards to the stations of the device by this conveyor. Obviously the method of depositing the packs or groups of packs on the conveyor 5 has no importance to the aims of the device.
  • a cutting device 11 of known type is used, located upstream of a station 1 which will be described in more detail hereinafter, and which comprises a rotating disc which is neared to the group of packs and cuts the straps or other binding holding the groups of packs 10 together.
  • a further, sub-dividing station 14 is provided, of known type, upstream of the station 1 and downstream of the cutting device 11, which removes a single pack 10 of tiles and deposits it at the station 1 which operates on single tile packs.
  • the device further comprises a deposit 15, downstream of the station, which will be better described hereinafter.
  • the station 1 comprises a raising device 2 which preferably includes a plate 2a connected to a first motor, of known type and preferably constituted by a cylinder, of which the stem 2b is illustrated in the figures.
  • the first motor vertically translates the raising devices 2 in both directions.
  • the plate 2a of the raising device 2 moves vertically between the belts 5 and, acting on the free central part 10c of the pack 10 of tiles, moves the pack 10 vertically from a first position A, in which the pack 10 is arranged on the belts 5 of the rest plane 5, to a second position B in which the pack 10 is brought into contact with a striker element 3, arranged above the rest plane 5, which comprises a plate which, by means of a cylinder 3a, can translate vertically in both directions on command.
  • the motor brings the pack 10 from position B into position A.
  • the station 1 further comprises at least one hooking device 6 which is shaped and arranged so as to hook an internal edge 10b of the border 10a surrounding the pack 10 when the latter is in the second position B.
  • at least one hooking device 6 which is shaped and arranged so as to hook an internal edge 10b of the border 10a surrounding the pack 10 when the latter is in the second position B.
  • two of the hooking devices 6 are provided, which are arranged laterally of two internal parallel and opposite edges 10b of the border 10a so as each to be able to hook one of the edges 10b.
  • each hooking device 6 comprises a plurality of rods, each having a hook-shaped end 6a which engages with the internal edge 10b of the border 10a
  • the hooking devices are positioned at the sides of the pack 10 so as not to interfere with the movement of the pack from position A to position B, and vice versa.
  • a second motor of known type and not illustrated in the figures, is provided, which, when the pack is in position B, moves the hooking devices 6 to bring the hooked ends into contact with the respective internal edges 10b of the border 10a. Once the internal edges 10a have been hooked-up, the second motor once more moves the hooks and draws the hooking device and the internal edges 10a away from the tile pack 10.
  • the second motor imparts the following movements on the hooking devices: a first movement on a horizontal plane to bring the hooks 6a under the tile pack 10, at the free zone 10c of the tile pack; a second, vertical movement so as to bring the hooks 6a into contact with the free zone 10c; a third movement on a horizontal plane so as to bring the hooks and the by-now attached internal borders 10a away from the tile pack 10. It is also possible, especially in devices destined to operate on a high number of packs having a same thickness, to treat the vertical movement of the device 6 as an adjusting movement for regulating the position of the devices 6 to the thickness of the tile packs 10.
  • the devices 6 will be provided with flexible elements (for example the rods can be made of small steel bars) which enable the hooks to make the first movement by sliding on the packaging surrounding the tile pack 10 without hooking onto it.
  • the hooking devices can be made differently from what is described herein, for example a single structure could be used, having the same section, instead of a plurality of rods, as long as the same functions are performed.
  • the station 1 further comprises gripping organs 4 which are arranged laterally of the striker element 3 and comprise suction cups 4a which can be activated on command in a way which will be described hereinafter.
  • the gripping organs 4 have the function of holding the border 10a when detached from the pack 10, and of carrying the detached borders 10a to the deposit 15 where the removed packs are collected.
  • Known type means for translation and/or raising are provided for translating and/or raising the gripping organs, and the border connected to it, from the station 1 to the deposit 15.
  • the device operates as described herein below.
  • the tile pack 10 or group of packs removed from the pallets are deposited on the belts 5 of the rest plane. If the pack is a single pack it is transported directly below the station 1. If it is a group of packs the cutting device 11 cuts the belts keeping the packs together, and once freed the packs are sent on to the sub-dividing station 14 which divides the packs 10 and deposits it on the station 1 which, as mentioned, operates on single packs 10. Once the pack has been placed in the station 1, which position is illustrated in figure 2, the station 1 carries out the operation as described herein below and as schematically illustrated in figures from 2 to 6.
  • the raising device 2 is activated and the plate moves vertically between the belts 5 in order to reach the free central part 10c of the pack 10 and to bring the pack 10 from the first position A into the second position B, illustrated in figure 3, in which the pack 10 is brought into contact with the striker element 3.
  • the hooking devices 6 which, as can be seen in figure 2, are positioned at the sides of the tile pack 10 so as not to interfere with the movement of the pack from position A to position B, make the first horizontal movement in order to bring the hooks 6a below the tile pack 10, at the free zone 10c of the tile pack 10. Then the second vertical movement is made, to bring the hooks 6a into contact with the free zone 10c of the tile pack 10 (illustrated in figure 4).
  • the gripping organs 4 are activated to grip the border 10a. Then the hooking device makes its third movement, bringing the hooks and the internal edges 10b connected thereto by the hooks away from the tile pack 10.
  • the hooks lacerate the contact points, generally glue-spots, which keep the packaging edges together, and the packaging and the tiles are thus freed one from the other.
  • the raising device 2 is then re-activated, with an oppositely-directed movement to the previous one, to bring the freed tiles from the second position B into the first position A; during this movement, the striker element 3 is translated vertically and downwards so as to ease separation of the tiles from the edges and to accompany the tiles in their downward movement.
  • Figure 5 illustrates this position.
  • the striker element 3 is raised and the hooking device disengages from the edge (figure 6).
  • the packaging is transported to the deposit 15.
  • the deposit 15 can also comprise devices, of known type, for directly treating the packaging and facilitating its removal; for example, a shredder could cut the packaging into small pieces.
  • the device can be provided with two lines, each provided with a station 1. In this case there will be a single group of gripping organs which will operate alternatively on one or the other line.
