Definitions

  • the object of the present invention is a compacting device for pressing ceramic articles, in particular plates, tiles and the like.
  • the invention also refers to a pressing device for ceramic articles.
  • the invention is particularly advantageous in a device for pressing ceramic articles, ideated by the applicant itself and known in the field from the publication EP1500480 , in which the powder material to be pressed is arranged in layer form on an abutment plane constituted by the upper face of a conveyor belt, which is slidably supported on a pressing member or lower pad.
  • the pressing is executed with a pressing member or upper pad through the interposition of a closed-loop belt, whose external surface is directed towards the conveyor belt.
  • the upper pad is provided with a frame, fixed or replaceable, that projects downward.
  • a forming frame also has the task of generating in the load, following the pressing, an edge characterized by a compaction or material density greater than that of the internal zones, wherein by greater material density it is intended a reduction of the overall space occupied by the material.
  • the presence of denser and more compact lateral zones considerably simplifies the removal and trimming of the loads after pressing. This occurs since the denser zones can perfectly withstand, without crumbling, the removal of the incoherent material that is situated along the external edges of the pressed load, allowing the obtainment of precise, clear edges of the load.
  • the currently available device while being effective and functional, can be improved regarding flexibility with respect to the change of size of the articles to be pressed. Indeed, in the currently available device, changing the size of the ceramic article requires changing the projecting frame with a frame shaped for executing the pressing of the new size. This represents a drawback both regarding processing times, since the substitution of the frame requires stopping the pressing line, and regarding costs, since it requires the availability of a certain number of different-size frames.
  • the object of the present invention is to offer a compacting device that allows overcoming the abovementioned drawbacks.
  • One advantage of the compacting device according to the present invention is to allow a change of size in considerably lower times with respect to those of the currently available devices.
  • the compacting device according to the present invention is particularly but not exclusively recommended for being used in a pressing device provided with a conveyor belt (T) that is movable along a main direction (X), for the forward movement of a load (S) of incoherent ceramic material to be pressed.
  • a press (P) is arranged along the conveyor belt (T) in a manner so as to receive the load (S) carried forward by the conveyor belt (T). Both the belt (T) and the load (S) arranged on the belt (T) move between the two pads of the press (P), such that the load (S) is pressed directly on the belt (T).
  • width will indicate a size measured on a horizontal plane perpendicular to the main direction (X), while “height” or “thickness” will indicate a size measured along a vertical direction.
  • the compacting device comprises a first leveler (2), which is structured to come into contact with two lateral zones of the load (S) and to push such lateral zones towards one another, perpendicular to the main direction (X).
  • the first leveler (2) in other words, compacts the load (S) perpendicular to the main direction (X), pushing the two lateral zones thereof, which are overall parallel to the main direction (X), towards one another.
  • the incoherent material of the lateral zones of the load is collected, forming two stacks (As), substantially parallel to the main direction (X), whose maximum level exceeds the level of the remaining zones of the load (S) itself.
  • the first leveler (2) comprises a pair of side walls (21,22) movable towards and away from one another along a horizontal direction, perpendicular to the main direction (X).
  • the intervention of the side walls (21,22) is actuated during a rest phase of the load (S), i.e. during a stop of the conveyor belt (T).
  • a load (S) is carried into and stopped in an intermediate position with respect to the side walls (21,22). Starting from a position of maximum mutual distance, in which they do not interfere with the load (S), the side walls (21,22) are moved closer together by means of actuators that are not illustrated in detail, for example pneumatic or hydraulic cylinders.
  • the side walls (21,22) By moving closer together up to a minimum distance position ( figure 4 ), the side walls (21,22) come into contact with the lateral zones of the load (S), creating the previously-described stacks of greater height. Once the step of compaction of the lateral zones of the load (S) has terminated, the side walls (21,22) return to the maximum distance position, such that the load (S) can once again be moved forward and a new load (S) can be carried to the side walls (21,22).
  • the actuators which drive the side walls (21,22) can advantageously be remotely controlled by means of a control module, for example in order to adapt the travel of the side walls (21,22) to different-size loads (S).
  • the side walls (21,22) have a front surface, intended to come into contact with the load (S), which is arranged in a substantially vertical position.
  • the side walls (21,22) can have the form of laminas or strips, arranged with the greater surface thereof vertical.
  • the front surface of the side walls (21,22) could also assume a different shape, e.g. convex or tilted.
  • the first leveler (2) comprises a pair of side walls (21,22) arranged to converge with each other in a forward direction of the load (S).
  • the lateral zones of the load (S) come into contact with the side walls (21,22), and are compacted, during the transport of the load (S).
  • the side walls (21,22) remain fixed during the forward movement of the load (S).
  • Each side wall (21,22) comprises a front surface, directed towards the belt (T) and towards the other side wall, situated above the belt (T), at a height such to be able to come into contact with the load (S).
  • the height of the side walls (21,22) can be adjustable with respect to the conveyor belt (T), in order to adapt the position of the side walls (21) to the thickness or height of the load (S).
  • the position of the side walls (21,22) can be adjustable along a horizontal direction perpendicular to the main direction (X), in order to allow adapting the position of the side walls (21,22) to the width of the load (S), as well as adjusting the level of compaction on the lateral zones of the load (S), and hence adjusting the height of the stacks that are formed in the lateral zones of the load (S).
  • motorized or manual regulators In order to adjust the position of the side walls (21,22), it is possible to arrange motorized or manual regulators, as is within the capacity of the man skilled in the art.
  • the use of motorized regulators allows modifying the position of the side walls (21,22) by means of remote controls, for example for an adaptation to loads (S) of different size.
  • the side walls (21,22) are in the form of laminas or strips, arranged with the greater surface thereof in substantially vertical position.
  • the compacting device can also be provided with a second leveler (3), which is structured to come into contact with a front zone and with a rear zone of the load (S) and to push such zones towards one another, parallel to the main direction (X).
  • the second leveler performs, on the front zone and on the rear zone of the load (S), the same action that the first leveler (2) performs on the lateral zones of the load (S).
  • the incoherent material of the front and rear zones of the load is collected, forming two stacks (Af,Ar), substantially perpendicular to the main direction (X), whose maximum level exceeds the level of the remaining zones of the load (S) itself.
  • the load (S) then has a substantially rectangular perimeter zone, comprising a stack (As,Af,Ar) of incoherent material whose maximum level exceeds the level of the remaining zones of the load (S) itself.
  • a stack As,Af,Ar
  • the load (S) comprises a closed perimeter zone, which follows the entire border of the load (S) itself, in which the incoherent material has greater compaction and material density. This allows facilitating and making more precise the trimming operations of the entire border of the load (S).
  • the second leveler (3) is movable along a vertical direction between a lower position ( figure 1 ), in which it is able to come into contact with a load (S), and an upper position ( figure 2 ), in which it does not interfere with the load (S).
  • the second leveler (3) In the upper position ( figure 2 ), the second leveler (3) allows the transit of the load (S) on the conveyor surface (T).
  • Actuators of known type, not illustrated in detail, are arranged for allowing the vertical movement of the second leveler (3).
  • the second leveler (3) comprises a pair of side walls (31,32) movable towards and away from one another, parallel to the main direction (X).
  • the side walls (31,32) have a front surface, intended to come into contact with the load (S), which is arranged in a substantially vertical position.
  • the side walls (31,32) can have the form of laminas or strips, arranged with the greater surface thereof vertical.
  • Actuators that are within the capacity of the man skilled in the art can be used for driving the side walls (31,32). Such actuators can advantageously be remotely controlled by means of a control module, for example for adapting the travel of the side walls (31,32) to different-size loads (S).
  • the intervention of the side walls (31,32) is actuated during a rest phase of the load (S), or during a stop of the conveyor belt (T).
  • a load (S) can be carried into and stopped in a zone comprised between the side walls (31,32).
  • the second leveler (3) is moved into its lower position ( figure 2 ), in which the side walls (31,32) can come into contact with the load (S).
  • the side walls (31,32) are moved closer together by means of actuators not illustrated in detail, e.g. pneumatic or hydraulic cylinders.
  • the side walls (31,32) By moving closer to each other up to a position of minimum distance ( figure 5 ), the side walls (31,32) come into contact with the front and rear zones of the load (S), creating the previously-described stacks of greater height. Once the step of compaction of the front and rear zones of the load (S) has terminated, the side walls (31,32) return to the position of maximum distance and they are lifted towards the upper position, such that the load (S) can once again be moved forward and a new load (S) can be carried to the side walls (31,32).
  • the first leveler (2) is movable along a vertical direction between a lower position ( figure 2 ), in which it is able to come into contact with a load (S), and an upper position ( figure 1 ), in which it does not interfere with the load (S).
  • the first leveler (2) in the embodiment comprising the side walls (21,22), can be associated with the second leveler (3) in order to form a group that is integral with respect to the vertical translation.
  • the intervention of the two levelers (2,3) is actuated during a stop of the conveyor belt (T).
  • the two levelers which are initially found in upper position, are lowered into lower position. In such position, each successively executes its own compaction travel. Once the compaction travels have terminated, the two levelers (2,3) are brought back into upper position and the conveyor belt (T) once again moves forward towards the press (P).
  • the first leveler (2) could also not be integral with the second leveler (3) with respect to the vertical translation. This occurs since the second leveler (2) does not obstruct the forward movement of the load (S) when the side walls (21,22) are situated in widened position. The second leveler (2), during the operation of the pressing device, could therefore always remain in lower position, and be lifted for example for the execution of maintenance operations.
  • the compactor according to the present invention is particularly effective in a pressing device in which the conveyor belt (T) assumes a continuous configuration, or in a configuration in which it comprises a first portion (T1) and a second portion (T2), consecutive with respect to each other, which are movable independently of one another.
  • a feeding device (F) is arranged along an initial portion of the conveyor belt (T). If the conveyor belt (T) comprises the two portions (T1,T2), the feeding device (F) is arranged along the first portion (T1) in order to deposit a load (S) on the first portion (T1) itself.
  • the feeding device (F) is, for example, in the form of a hopper provided with a lower discharge opening.
  • the feeding device (F) operates on the first portion (T1), i.e. the loads (S) are deposited on the first portion (T1).
  • the front end of the first portion (T1) is at least partially above a rear end of the second portion (T2), at a height slightly greater than the second portion (T2).
  • first and a second portion (T1,T2), independent of one another, allows managing the intervention of the compacting device with considerable flexibility.
  • the first portion (T1) can be driven to move forward in order to allow the deposition of a load (S).
  • the step of depositing a load (S) can be synchronized with the intervention of the compacting device, so as to terminate before or simultaneously with the intervention of the compacting device.
  • the first and the second portion can be driven forward in order to execute the transfer of the load (S) deposited on the first portion, and to simultaneously transfer the load (S) that has undergone compaction towards the press (P).
  • the conveyor belt (T) comprises the first and the second portion (T1,T2) that are movable independently of one another, it is possible to form the stacks (Af,Ar) in the front and rear zones of the load by modifying the forward movement velocity of the two portions, in a manner such that, during the transfer of the front zone and of the rear zone of the load (S) from the first portion to the second portion, a reduction of the forward movement velocity of the load is produced. This causes the formation of the stacks (Af,Ar).
  • the front zone of the load (S) transits from the first portion (T1) to the second portion (T2)
  • the compacting device allows obtaining important advantages.
  • the compacting device allows attaining loads (S) with a perimeter zone of greater material density, without arranging pressing pads provided with projecting edges or frames. This allows reducing the cost of the pressing pads and simultaneously reducing the adaptation times with a change of size of the loads (S) to be pressed. Indeed, it is sufficient to modify the travel and/or the mutual distance of the side walls (21,22,31,32) in order to be able to attain the stacks (As,Af,Ar) in loads (S) of different size.
  • the changes of size of the loads (S) can be managed without having to stop the pressing line so to execute adaptation interventions; rather, it will suffice to simply adjust the travel or the mutual distance between the side walls (21,22,31,32).
  • Such adjustment can occur through remote controls on the actuators set for driving the side walls themselves, or on suitable regulators that can be arranged for the levelers (2,3).
