Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the conveyor consists of two, one behind the other in the direction of travel of the kiln cars and having a distance between them, the first in the direction of travel for conveying the documents from the stacking or unstacking device to the filling or emptying device and the second for Conveying is set up from the filling or emptying device to the stacking or unstacking device.
  • the function of the device e.g. in the area of an unloading station for the fired ceramic parts, the following is:
  • the documents loaded with ceramic parts are placed in rows arranged transversely to the longitudinal direction of the orbit on the first conveyor by means of the stacking and unstacking device and conveyed to the emptying device, where the cassettes are emptied.
  • the empty cassettes are conveyed again by the second conveyor under the stacking and unstacking device, which they stack again on the or a kiln car.
  • the ends of the conveyors facing the filling or emptying device are connected to one another by a third conveyor which conveys the cassettes from the first conveyor to a middle position between the latter and the second conveyor, in which the cassettes are emptied and then to the second conveyor.
  • the known design is very complex. This is due to the fact that the conveyor has two conveyors, which leads to high manufacturing costs. In addition, there is a significant space requirement not only for the first and second conveyor, but also for the third conveyor.
  • the first and the second conveyor are supported on a table which extends above the kiln car and is referred to as a work table. This designation is misleading because the table does not participate in the stacking or unstacking or in the conveyance of the cassettes to the filling or emptying device and back.
  • the table thus only serves to support the first and second and apparently also the third conveyor.
  • the invention has for its object to design a device of the type mentioned in such a way that, while ensuring simultaneous stacking or unstacking and filling or emptying of the documents, the conveyor can be manufactured more simply and in a smaller design.
  • the conveyor device comprises only one conveyor, whereby the desired simplification and small construction is achieved.
  • this conveyor the documents are conveyed from the stacking and unstacking device to the filling or emptying device and vice versa. This can be achieved by means of a reversible or reversible conveyor with regard to its conveying direction. Since there is no second conveyor according to the known configuration, there is also no need for a third conveyor, as is also the case with the known configuration.
  • the carrier which can be displaced in the longitudinal direction of the orbit and has at least two parking spaces or rows of parking spaces for the documents.
  • the carrier which can be displaced in the longitudinal direction of the orbit and has at least two parking spaces or rows of parking spaces for the documents.
  • at least one further parking space or a further row of parking spaces is thus available, onto which a document or a series of documents can be placed or removed; that is, the stacking and unstacking device and the filling or emptying device can work simultaneously.
  • FR-PS 2120 335 It is already known from FR-PS 2120 335 to use a conveyor device with only one conveyor in a device for loading or unloading kiln cars passing through a kiln for ceramic parts in an orbit, but in this known embodiment the filling or emptying device is not arranged to the side of the orbit, but integrated into the stacking and unstacking device. Simultaneous stacking or unstacking and filling or emptying is therefore not possible.
  • the conveyor serving for the removal or supply of only the ceramic parts is set up only for the conveyance into a conveying device.
  • a carrier according to the solution according to the invention is not provided in this known embodiment.
  • the aim is to arrange the loading station as close as possible to the furnace entrance and the unloading station as close as possible to the furnace outlet in order to avoid unnecessary conveyance of the ceramic parts into orbit and a consequent production delay.
  • This is possible by an embodiment according to claim 4, in which there are two devices, one of which is set up for loading and the other for unloading.
  • kiln cars 2 arranged one behind the other and only indicated in detail in FIG. 2 are advanced in the direction of travel (arrow 3). Ceramic parts, such as roof tiles, are stacked on the kiln car 2 in rows 4 arranged transversely to the direction of travel 3. The cassettes and the ceramic parts are not shown in detail. The representation of the cartridges as rows 4 is sufficient because the cartridges are handled in rows (rows 4).
  • the devices 5 and 6 are identical to one another; however, they are operated according to different working methods, the device 5 being arranged in the area of an unloading station 7 for unloading the roof tiles and the device 6 being arranged in the area of a loading station 8 and being operated for loading the kiln cars 2 with roof tiles.
  • Each device 5, 6 has a stacking and unstacking device in the form of a gripper which extends over the entire width (b) of the orbit 1 and is thus able to grip a row 4 of the cassettes at the same time.
  • the gripper can be moved in height and in the longitudinal direction of the orbit 1 and is indicated by gripping jaws 9 which can move towards and away from one another.
  • Each device 5, 6 further comprises a conveyor 10 arranged transversely to the orbit 1, which is arranged above the orbit 1, ie above the kiln car 2, and extends transversely to the orbit 1 up to a filling or emptying device 11, 12.
  • the filling and emptying device 11, 12 is assigned a gripper which can also be moved vertically and along the orbit 1, with which a row 13 indicated by a broken line can be handled in a manner to be described.
  • the device 12 is followed by a discharge conveyor 14 which, viewed in the longitudinal direction of the orbit 1, can be arranged in front of, behind or to the side of the free end of the device 12.
  • a discharge conveyor 14 which, viewed in the longitudinal direction of the orbit 1, can be arranged in front of, behind or to the side of the free end of the device 12.
  • a feed conveyor 15 which differs from the discharge conveyor 14 only in its conveying direction, which is opposite.
  • Each device 5,6 also has a carrier 16 with two parking spaces 17, 18 for cassettes, the top of which is adapted to the conveying surface of the conveyor 10, and between a position shown by solid lines and a position indicated by dash-dotted lines back and forth, that means along the orbit 1, is displaceable.
  • the drive for the carrier 16 is not shown for reasons of simplification. For example, it can be a hydraulic piston-cylinder drive.
  • the guides for the carrier 16 are indicated in FIG. 2 and designated 19, in which the carrier 16 is guided with rollers 21. In the displacement end positions of the carrier 16, either the parking space 17 or the parking space 18 is aligned with the conveyor 10, that is to say the length of the displacement path corresponds to the center distance between the parking spaces 17, 18.
  • the mode of operation of the device 5 is described, namely the unloading of the roof tiles.
  • a row 4 of cassettes filled with roof tiles is transferred from the position designated A) to the kiln car 2 to the parking space 18, that is to the position C), by means of the gripping jaws 9.
  • the conveyor 10 then conveys this row of cassettes from the parking space 18 to the emptying device 12, where the row of roof tiles, indicated and indicated by a dotted line, is transferred to the discharge conveyor 14 and discharged by means of the gripper indicated by gripping jaws 22.
  • the row of empty cassettes located in the emptying device is then conveyed back to the parking space 18 by means of the conveyor 10.
  • a next row 4 is transferred from the kiln car 2 to the parking space 17 of the carrier 16.
  • the carrier 16 is shifted to the right in the drawing, so that the parking space 17 with the row of filled cassettes located thereon is in alignment with the conveyor 10, and the parking space 18 the position indicated by dash-dotted lines, that is to say the position denoted by D), occupies.
  • the next steps are to convey the row of filled cassettes, which are now in alignment with the conveyor 10, to the emptying device 12, to empty them and to convey them back to the carrier 16.
  • the row of empty cassettes located in position D) is transferred by means of the gripping jaws 9 to a position labeled E) on the kiln car 2 and, if necessary, stacked.
  • the carrier 16 finally moves back into the position shown with solid lines, the parking space 18 - position C) - free and on the parking space 17 - position B) - the last emptied row of cassettes is located.
  • the next step is to move a next row of filled cassettes from position A) to position 18 - position C.
  • the empty row of cassettes is transferred from parking space 17 - position B) - to position E) onto the kiln car 2 and another row 4 of filled casings set from position A) to parking space 17 - position B) - transferred, which is done by the gripping jaws 9. It is also possible to always transfer this row 4 from A) to C), but in the case of the parking space 17, this must first be pushed in line with the conveyor 10.
  • the rows of cassettes can also be emptied, the rows of filled cassettes can be translated onto the carrier 16 or the rows of empty cassettes can be translated from the carrier 16 onto the kiln car 2 - position E) - simultaneously.
  • the slot 18 - position B) - is emptied as well as occupied and during the conveying and emptying of a row of cassettes from the slot 17, the slot 18 - position D) - is cleared.
  • the operation of the device 6 for loading the kiln car 2 with filled cassettes is corresponding; compare gripper jaws 9, positions A) to E) and parking spaces 17 and 18. There is only the difference that rows 4 with filled cassettes, rather than rows 4 with empty cassettes, are transferred from the storage section between the devices 5, 6 to the carrier 16 transferred and rows 4 filled cassettes on the kiln car 2 - position E) - are transferred.
  • the respective row 4 cassettes are filled by translating the roof tiles from the feed conveyor 15 into the row 4 cassettes by means of the gripping jaws 22.
  • the work steps for unloading or loading can be controlled automatically or by a program.
  • the conveyor 10 consists of a single conveyor section 25 which extends up to the carrier 16.
  • the conveyor section 26 is part of the carrier 16 and can be pushed back and forth with the latter. It is therefore necessary to design the conveyor section 26 so wide that it extends over both parking spaces 17, 18, or to arrange two individual conveyor sections 26 one behind the other in the region of the parking spaces 17, 18, as seen in the longitudinal direction of the orbit 1.
  • the displaceable carrier 16 is no longer attached above the orbit 1, but is instead moved into the filling or emptying device 11, 12.
  • the design of the device for loading and unloading is identical to the design described above in FIG. 1, so that a further explanation is unnecessary in this regard.
  • a row of cassettes filled with roof tiles is transferred from the kiln car 2 to the conveyor 10 by means of the gripping jaws 9.
  • the latter then conveys the row of cassettes to the emptying device 12, in which e.g. the parking space 18 of the carrier 16 is in position C), aligned with the conveyor 9, in order to receive the row of cassettes being conveyed.
  • a row of filled cassettes located on the parking space 17 (item B) is emptied by means of the gripping jaws 22 and the row of bricks 13 removed is transferred to the discharge conveyor 14.
  • the carrier 16 is moved into the position indicated by dashed lines, in which the parking space 17 in position C) is aligned with the conveyor 10, and the parking space 18, which is occupied by a row of filled cassettes, occupies position D).
  • the emptied row of cassettes located on the parking space 17 is conveyed back to the orbit 1 via the conveyor 10 and transferred to the kiln car, whereupon a further row of filled cassettes is transferred from the kiln car 2 to the conveyor 10 and conveyed to the emptying device 12 and to the parking space 17 of the wearer.
  • the row of cassettes located in the parking space 18 in position D) is emptied.
  • the carrier 16 is then moved back into the position shown with solid lines, in which the parking space 18 in position C) is aligned with the conveyor 10, and the parking space 17 assumes the position B).
  • the parking space 18 is again filled with a row of filled cassettes in the manner described and the filled cassette row at the parking space 17 is emptied at the same time.
  • the operation of the device 6 for loading the kiln cars with filled rows of cassettes is corresponding, with 11 rows of empty cassettes being transferred to the parking spaces 17, 18 of the carrier 16 in the filling device, and the filling of the rows of cassettes by translating the roof tiles from the feed conveyor 15 by means of the gripping jaws 22 he follows.
  • the parking spaces 17, 18 of the displaceable carrier 16 integrated into the filling or emptying device 11, 12 can be designed as a conveyor in a continuation of the conveyor 10, analogously to the exemplary embodiment according to FIG. 2.
  • the rows of cassettes can be transported on the conveyor 10 on a pallet.
