DE2905309A1 - Automatic stacker for loading moulded bricks onto kiln cars - where bricks stand on edge, and are prevented from falling over by guide rails - Google Patents

Abstract

The bricks are moulded by hand or by machine, and are placed on frames or drying pallets from which they are to be transferred to, and stacked on, kiln cars. The transfer and stacking devices form cassettes which hold the bricks so the latter cannot tilt while they are being transferred to the kiln cars. The pref. plant consists of several conveyors, and a tilting device which tilts each brick through 90 degrees so the bricks stand on edge on an intermediate conveyor. This conveyor and the subsequent stacking appts. are fitted with side rails which align the rows of bricks and also prevent the bricks from falling over. The overall result is a reliable stacker which eliminates manual labour.

Description

Device for transporting and stacking by hand and

machine-formed stones from drying pallets or frames on tunnel kiln cars.

The invention relates to a device when transporting in particular bricks made in the Tlandstrich-Verfahrcn, which by the unevenness Their geometrical shape is not, as is usual with machine-formed stones, in a lateral edge can be transported freely.

A mission. however, this device is for machine-formed stones also possible.

There are a number of devices for transporting machined items Bricks and known for stacking these stones on furnace wagons, but they without exception, carry out the transport of these stones in a free lateral position.

because these devices are loaded with hand-painted stones, These tip over in an uncontrolled manner on their transport route and thus prevent the automatic Sequence of the transport and stacking process.

The purpose of the invention is to eliminate this drawback and one ensure automatic transport and loading process without manual intervention.

This is achieved by the fact that they are manufactured using the Hanistrich process and dried stones from the beginning of the installation in the side edge position corresponding devices are supported laterally so that during the entire Transport path tipping over of the stones is prevented mechanically.

In the following, the invention is explained by means of only one bus routing example illustrative drawing, explained in more detail.

They show: Figure 1 1 turning device that removes the stones from the flat edge brings into the side edge position with a subsequent intermediate conveyor and side guides.

Figure 2 1 transfer device, the arriving as a strand of stones to preprogrammed groups of 2, 3, 4 or more stones singly and on one Transfer device passes.

Figure 3 1 view from above of the entire system.

Figure 4 1 side view of the intermediate table of the single gripping drawing and the gripper plate.

In Figure 1, Pos. 1 shows the turning angle that the stones Take item 2 from the flat edge position of a feed belt and move it to the side edge position on a short intermediate conveyor Pos, 3, on which it is resilient Adjacent lateral guide rails Pos. 4 are held in the side edge position.

The intermediate transporter pos. 3 brings the stones up to a stop Pos. 5 in Figure 2, in its end position corresponding to the amount of the program determine stones is changeable.

A rocker pos. 6 then removes 2, 3, 4 or more stones, each after position of the stop pos. 5 and pushes it onto a further conveyor pos. 7 Holds on to the onward conveyor while the stones are being transferred by the rail a holding device Pos. 8 firmly the last stone of the strand, so that a cross slide is prevented by stones.

On the onward conveyor, the stones are removed from sheet metal strips Pos. 9 pushed and laterally by resilient stops pos. 10 in Figure 3 and one fix arranged guide bar pos. 11 out.

When the transport device is filled with stones in all compartments is, these are from the single gripping device Pos. 12 with their grippers Pos. i3 (Figures 3 and 4) detected, lifted itnd rotated depending on the program over the intermediate table Pos. 14 brought from FIG.

This intermediate table pos. 14 is from back to front in. Direction loaded onto the transport device in such a way that when lowering the gripper the spars pos. 15, from which the intermediate table consists, with the stones facing down be pressed, so that between the cbenbleibenden spars pos. 15 and the crossbars Pos. 16 cassettes are created which prevent the stones from tipping over.

When the other stone layers are placed in front of them, the ones underneath also become Holme pos. 15 pressed down, so that now the stones in front of the already set The stacked stones, in turn, prevent the previously stacked stones from tipping over.

When the Ztfisonentisch pos. 14 is completely loaded, takes over Gripper plate from Figure 4 Pos. 17 the entire stone layer from the intermediate table Pos. 14 and brings them onto the tunnel kiln carriage pos. 18 when the stones are lifted from the intermediate table Pos. 14, all spars Pos. 15 are pneumatically returned to their original position for the next loading process is pushed up.
