Method and device for destacking and stacking Cassettes from and on the kiln car

The invention relates to a method for unstacking and stacking U-shaped, roof tile-bearing cassettes from and on kiln cars, with the features listed in the preamble of claim 1. The invention also relates to a Facility for carrying out this procedure, with those in the preamble of claim 3 features described.

In a known method of this type (DT-OS 27 05 074) the cassettes loaded with fired roof tiles are lifted off the kiln car at an unstacking point, and one by one to an unloading point transported, unloaded there, then brought back together in a row and stacked empty again on the kiln car. Of the The kiln car is now transported to a stacking point, where the empty cassettes are lifted off the kiln car and closed individually transported to a loading point and loaded there with dried roof tiles. Then the loaded cassettes are closed grouped in a row and stacked on the kiln car .

This is a very cumbersome process because of the cartridges twice removed from the kiln car and accordingly have to be stacked twice. Apart from the unnecessary loss of time, The process that occurs in this process involves a considerable amount of known processes constructive effort ahead, as a separate üntstapelbtelle and a separate ülapelstelle are available that spatially are separated from each other at a greater distance.

Due to the spatial separation of the unstacked place and the stacking point from each other and because of their complicated structure, the device performing the known method requires one considerable space requirements.

In addition, the cassettes, which have to be made of refractory material and are not exactly cheap, as a result of the many Destacking, stacking and transport processes are damaged. This occurs in particular when the cassettes lying in rows are dismantled or when the cassettes are subsequently regrouped into rows because the cassettes collide and rub against each other.

The invention is based on the object of providing a method for unstacking and stacking cassettes from and onto kiln cars create, which can be carried out on a small surface area and with little expenditure of time and in a way that is gentle on the material can that the device for carrying out the method as low a structural effort as possible with spatial association the destacking and stacking point for the kiln car requires and only one workflow for destacking and stacking the Makes cassettes necessary, with a storage of the cassettes in the workflow if necessary to bridge any malfunctions should be made.

This task is carried out in the process by those in the identifying Parts of claims 1 and 2 described features solved.

The inventiveness / experience points towards the known Method in so far a substantial improvement, as αϊε Cassettes are transported on pallets in a manner that is gentle on the material and only necessarily once during the unstacking or stacking process with mechanically operating devices in contact come.

The method is advantageously carried out on a smaller area, da lint stacked and stacked bars were brought together in one place are.

In addition, after unstacking, there is no need to pull the cassettes apart and then regroup the cassettes into a row. The cassettes are received in a row tightly against one another by the kiln cars and remain in this position throughout the A _r beitsablaufes lying on the pallets and therefore need no new grouping to be subjected. On the one hand, this saves time and, on the other hand, the cassettes are handled carefully, as damage cannot occur.

The task set is also provided by a device for carrying out the method with the parts indicated in the characterizing parts the features described in claims 3 and 4 solved.

When combining the iintstapel and 3apelstelle in one place the particular advantage that the facility can be produced without great design effort. It is simple to carry out and allows for a great deal of work Performance of destacking and re-stacking the cassettes in a circulation process.

It is also advantageous that the cassettes on the storage table can be saved if z. B. a disruption in the workflow or the pace of work at the unloading point and the Loading point does not match.

If there is a shortage of cassettes, these are removed from the storage table and reintroduced into the workflow .

The gripper device _? taking a series of the above and next stacked and loaded with fired tiles cassette 4, it lifts from the kiln car 1, and places them on a pallet 5, which are conveyed on a conveyor zoom. 6

The pallet 5 with the cassettes 4 loaded with roof tiles now passes from the conveyor 6 onto an unloading track 7, which carries the Pallet Jj transported past an unloading point 8, where the Roof tiles are removed from the cassettes 4 so that they are conveyed on empty, namely in the area of a transverse to Unloading track 7 arranged collecting device 9. This happens by one of the unloading conveyor 7 associated raisable and lowerable roller conveyor 7a.

A number of pallets 5 with the cassettes 4 on them collected next to each other, so that pallets 5 are buffered here in order to ensure continuous loading of a loading track 11 running transversely to the collecting device 9. The loading track 11 is loaded by a loading device 10, which

each a pallet 5 with the empty cassettes ^; i picks up from the collecting device 9, transports it to the loading track 11 and sets it down there.

The loading track 11 conveys the pallet f past a loading point where the cassettes 4 are loaded with dry roof tiles or panels. The loading track 11 extends into the region of a Ctapelstelle 13 into it and here the pallet '} to an adjusting device 14 from which accurately adjusts the cassette. 4 A gripper device prior year is now taking over the adjusted cassette 4, it lifts from the pallet ^ and puts them on the now empty Ofenviagen 1 in rows above and stacked side by side again.

The emptied pallet 5 is transported on the conveyor 6, here collected with other empty pallets 5 and fed to the destacking point.

If the kiln car 1 is filled with cassettes 5, it is placed in the tunnel kiln (not shown) supplied.

If a disturbance occurs at the loading point 12 during the work process or if the pace of work at the unloading point 8 is greater than that at the loading point 12, the emptied cassettes 4 with the pallets 5 ^ν ° ^{η of} the collecting device 9 are placed directly next to the unloading path 7 Transport path 16 is conveyed and passed by this to the conveyor 6, from which the gripper device 3 picks up the pallets 5 and the cassettes 4 and brings them to a storage table 17 and stacks them here for storage. The storage takes place until the disturbance at the loading point 12 has been eliminated or the working pace of the loading point has adjusted to that of the unloading point 8.

If there is a fault at the unloading point 8 or if the pace of work is slow at the loading point 12 is greater than that at the unloading point 18, the stored cassettes 4 are returned to the Workflow introduced by the gripper device 3 the Pallets 5 and the empty cassettes 4 on them from
