Abstract

The invention relates to an apparatus for transporting slat-shaped green brick supports between the dry side and the wet side in clay works in the ceramics industry. A collection point located on a conveyor track (2) and a storage point (9, 10) located underneath a gripper apparatus (7) which can be moved on a crane track (6) are provided for the slat-shaped green brick supports (1). The slat-shaped green brick supports (1) are connected in layers of slats at the collection point (3), which lies outside the crane track (6) and is designed for two layers (4 and 5) of slats. Adjoining the collection point (3) and underneath the crane track (6), which extends transversely to the conveying track (2), is a stacking point (8) on the conveyor track (2) for layers (4, 5) of slats stacked crosswise one above the other. For the crosswise stacking one above the other, a stacking fork (12) is provided which can be rotated through 90 DEG about an axis (13) of rotation, receives the layer (5) of slats brought by the conveyor track (2) by means of angled pieces (15, 16) and lays them down, rotated through 90 DEG , on the layer (4) of slats located in the stacking point (8). The gripper apparatus receives the layers (4, 5) of slats, lying crosswise one above the other, and feeds them to the storage point (9, 10). It is also possible to convey the layers (4, 5) of slats direct to the wet side, through the stacking fork (12), by means of the conveying track (2). <IMAGE>

Description

Device for transporting slatted molded carriers.

The invention relates to a device for transporting slat-shaped Mold carriers between the dry and wet side in clay works in the ceramic industry, with the features listed in the preamble of claim 1.

DE-PS 16 83 867 already discloses a device for transporting known of slat-shaped molding carriers, in which the molding carrier of the Dry side in the area on a crane runway movable gripping device to a collection point where the molding carriers are transported to a slat layer to be collected. The gripping device grasps the slat layer at the ends the molding carrier with holding elements made of angle iron lifts the molding carrier from the collection point and either transports them to a storage location where the Slat layers are stacked crosswise, or the gripping device lays the slat layer on one of the molded carriers leading back to the wet side Conveyor device from between the collection point and storage location at right angles is arranged to the direction of travel of the gripping device.

Because the slat layer is below the crane runway in the area of the gripping device is formed, the gripping device must wait until a slat layer is formed pause and only then can remove the batten layer. Since always If only one layer of batten can be transported, the device works slowly and can only be used up to a performance given by the circumstances described will.

The object of the invention is therefore to provide the device mentioned at the beginning to improve the transport of slat-shaped molding carriers so that the Transporting and storing the batten layers is going on faster.

This object is achieved according to the invention by the in the characterizing part of claim 1 listed features solved.

Another advantageous embodiment of the invention is the subject of claim 2.

Because several layers of laths are formed outside the crane runway and these are stacked crosswise by a stacking fork the removal of the slat layers to the storage location in several layers on top of each other, thereby achieving greater performance.

Because the gripping device no longer crosses the slat layers rotates, but this is done from the stack fork, can by omitting the the crane runway required for turning the gripping device be designed lighter and lower.

In the drawing is an embodiment of the subject matter of Invention illustrated schematically in a plan view.

In the drawing the invention is applied to such devices illustrates how they are transported and / or stored or

Feeding of empty slat-shaped briquette carriers in brick factories preferably apply.

The lath-shaped molding carrier 1 are in the direction of the arrow A brought in from the dry side on a conveyor track 2 and in a collection point 3 collected into several layers of batten 4, 5. The conveyor track 2 conveys the slat-shaped molding carrier 1 from the area of the dry side in the direction of the Arrow B in the area of the wet side.

The conveyor track 2 is crossed by a crane track 6, on the one Gripper device 7 is arranged to be movable back and forth. Below the crane runway 6 in the area of the conveyor track 2 is a stacking point 8, while to both Pages of the stacking location 8 several storage locations 9, 10 are provided, which also located below the crane runway 6. Following the stacking point 8 is a provision 11 is provided, to which a stacking fork 12 is assigned, which to an axis of rotation 13 is rotatable in the direction of the double arrow C by 90 ".

The stack fork 12 consists of one attached to the axis of rotation 13 horizontal cantilever arm 14, which is arranged at a distance above the conveyor track 2 and from angle pieces 15 arranged at a distance from one another on the cantilever arm 14 and 16, the slat-shaped lying on the conveyor track 2 in a slat layer 15 Grasp molding carrier 1 at the ends.

The mode of operation of the embodiment shown in the drawing is as follows: In the collecting point 3, two layers of laths 4 and 5 are collected and conveyed further in the direction of arrow B by means of the conveyor track 2.

If there is now a shortage of mold carriers on the wet side, both will Slat layers 4 and 5 transported through the stacking fork 12 through directly to the wet side, where they are covered with moldings.

However, if the wet side is adequately supplied with molding carriers 1, the slat layers 4 and 5 are transported forward to the stacking point 8 or the provision point 11. The front slat layer reaches the area of the stand 11 while the rear slat layer 4 remains in the area of the stacking point 8.

During this sequence of movements, the stacking fork 12 is located with the elbows 15 and 16 in the lowered state, so that they are the incoming Lath layer 5 or the lath layers 4, 5 running through to the wet side not with special needs. Thereafter, the stack fork 12 lifts the slat layer 5 through the angle pieces 15 and 16 from the conveyor track 2 and pivoted in the direction of the Double arrow C by 90 ° and places the slat layer 5 crosswise on the in the stacking point 8 lying slat layer 4 from (dashed position). The stack fork 12 is but after the pivoting process and before the lowering process in the raised state Held above the slat layer 4 when the wet side requests molding carrier 1. The conveyor track 2 can therefore also in this state, the wet side with the molding carrier 1 load.

If the slat layer 5 is now placed on the slat layer 4, it lowers the gripping device 7 and engages below with angular holding elements 17 and 18 the lower slat layer 4 at the ends of the molding carrier 1 and transported the slat layers 4 and 5 to one of the storage locations 9 or 10. The stack fork 12 then swivels back into the starting position.

Is now the transport path length for two slat layers due to time constraints 4, 5, the gripping device 7 remains with the gripped slat layers 4 and 5 above the stacking point 8 in the waiting position until in the stacking point 8 two other slat layers 4, 5 lie one on top of the other. The gripping device lowers then off and places the gripped slat layers on those in the stacking point 8 Layers of batten off so that a stack of 4 layers of batten is formed. The gripping device 7 then opens the holding elements 17, 18 and engages below with the holding elements 17, 18 the lowest slat layer lying on the conveyor track 2 and now lifts it 4-layer stack from the conveyor track 2. This work cycle can continue until a stack of 6, 8, etc. layers is formed in the gripper device. The finished stack is then deposited in the storage location 9, 10.

Since the gripping device 7 does not rotate 90 ", the guide the gripping device 7 are attached below the crane runway 6, whereby then the gripping device is always guided and the device is significantly lower expands.

The return transport of the slat layers 4, 5 from the storage location 9, 10 to the stacking point 8 is done in reverse, by the gripping device 7 removes two slat layers 4, 5 from the storage location 9, 10 and on the stacking location 8 after swiveling in the stacking shelf 2 drops. The stacking fork 12 grips under the stack layer 5 located above, swivels it by 90 "and closes it Removal on conveyor track 2.
