Description

System for loading and unloading a tunnel dryer for ceramic Products The invention relates to a system for loading and unloading a Tunnel dryer for ceramic products and one above the loading time of the drying car lying product throughput time with a conveyor track running parallel to the dryer with loading point and unloading point. for drying trolleys and one transfer table each with carriage pushing device between the dryer track ends and conveyor track ends.

To accommodate surplus, with fresh briquettes during the loading time occupied drying trolley or to park outside the unloading time from the Drying wagons with extended drying wagons with dried bricks, it is known lay sidings in front of and behind the tunnel drying facility.

The sidings take up a lot of space, while also outside the move the drying wagons from the conveyor track to the storage or drying tracks Transfer platforms separate conveyors must be available, which the on move the wagons located in the siding.

The invention is based on the object of creating a system the transport process, especially outside of the loading times, if there is little space required, simplifies and makes it possible to automate this with the simplest of means.

The system described at the beginning is marked for this purpose by one or more parallel to the drying track and conveyor track Buffer tracks, which are caused by transfer platforms moving in the same direction at the same time Periodically loaded in the rhythm of the dryer feed instead of the dryer and be emptied. Another feature of the invention is a distance carriage between the wagons with dry and fresh bricks on the buffer track.

The system according to the invention is required for loading and unloading the drying room an extremely small space, while at the same time by omission separate carriage conveyors, the investment costs can be reduced considerably. In particular, the transport process of the car is and can be significantly simplified can be done fully automatically at no significant cost.

An embodiment of the invention is shown in the drawing.

In a loading point 8, the briquettes to be dried are on the Drying car 10 deposited. As soon as a wagon is filled with fresh bricks, A transport device promotes him to the electrically driven transfer table 11. This concerned about the sliding platform track 13 the entry of the drying wagons 10 in the tunnel drying facility 1 and parking the reserve car 10 on the buffer track 5.

When the bricks are dry, the appropriate drying carriages are installed 10 pushed onto the extendable sliding platform 3, which carries the car over the sliding platform track 2 to conveyor track 6, where it is transferred from a transport device to the unloading point 7 to be drawn. The empty drying wagons are pulled up to loading point 8. The entire transport process can be carried out automatically without any human intervention Work force.

In the case of the drying facility shown, the drying time is 24 hours accepted. During 8 working hours twelve drying carriages 10 are loaded with fresh Formings occupied. Over the unloading point 7 are also during these 8 hours twelve wagons unloaded. The loading and unloading operations are suspended for the remaining 16 hours. Since the drying plant has to be continuously loaded, a third of those are fresh Drying wagons 10 occupied briquettes during the 8 working hours in the dryer 1 to drive. The rest is parked on a buffer track 5, from which z. B. During the evening and night hours, the car 10 is removed and taken to the drying plant 1 to be pushed. With a drying capacity of twelve wagon loads per day the dryer 1 must also be designed to accommodate twelve wagons 10. Two Thirds of the wagons with pressed bricks are opened during loading parked on buffer track 5. This track 5 must therefore accommodate eight drying wagons 10 can. The electric transfer platform 11 on the entry side takes over a car 10 from conveyor track 6, drives to dryer 1 and pushes the car with a built-up one Feed device 12 onto track 14 of tunnel dryer 1.

At the same time, the entire row of wagons in dryer 1 is in motion set so that the last car 10 with dried briquettes on the also The driven platform 3 is pushed, which brings this car to the conveyor track 6 and here with the feed device 4 settles. The second and third with fresh Car 10 occupied by briquettes is not put into drying room 1, but onto the buffer track 5 driven. The same game is repeated here as before drying room 1. Open the buffer track 5 are wagons with dry bricks, which in the evening and night hours have been dropped off here. But since the buffer track 5 only contains eight wagons 10 and the length of this track must be the same as that of drying room 1 is A spacer carriage 9 is arranged between the carriage 10 with dry and wet briquettes, which bridges the length of four car 10. So if a car 10 with fresh Briquettes are driven onto the buffer track 5, becomes one with dry briquettes loaded carriage 10 pushed off and taken over by the waiting transfer platform 3.

Outside the working hours of the loading operation, the Car 10 parked on buffer track 5 can be driven into dryer 1.

For this purpose, the last one driven out of dryer 1 before the end of operations Car 10 not driven to conveyor track 6, but to buffer track 5 and deposited here. The drive-in platform 11 is ready on the entry side and thus takes it from the buffer track 5 pushed off carriage 10, which is then transported to the dryer 1, whereby Again a carriage 10 pushes out of the dryer 1. At the start of operations the buffer track 5 contains only dried bricks.

The whole process, i.e. bringing the fresh briquettes into the dryer 1, parking the wagons 10 on the buffer track 5, leaving the dry bricks is fully automatic through a program controlled, however at any time the possibility manual intervention is given.

Instead of the depicted drying facility with a drying facility track Drying plants can also have several tracks, with us and ours in the same way with a: correspond. Counting buffer tracks and in adjustment the respective operating conditions, drying, working and loading times, Material properties, number and size of the dryer wagons or corresponding funding and the like. Can take place.
