Abstract

Device for the transfer of brick blanks made in an extrusion press and with a pre-selected length, onto pallets, using a transfer track(1) for the brick blanks above a pallet feeder track(2) which is located at 90 degrees to track (1), and with a transport track (3) running in the same direction as track(1) and moving groups of pallets underneath track(1) to a junction between tracks (1,3). Track (2) consists of an outer section and an inner section sepd. by limit stops mounted on pivots, the stops being released while the prescribed no. of pallets, e.g. two, pass onto the inner section but the stops then switch off the outer section of track(2), the track movements being automatically controlled by programmed switching. Used for automatic loading of extruded blanks onto two pallets located side by side.

Description

Device for transferring by means of an extruder into optional Brick moldings produced with a predetermined overall length on pallets the The invention relates to a device for transferring by means of an extruder Brick shapes produced in an optional predetermined length on pallets, with a transfer lane for the bricks, one below it feeding track for the pallets running across the production line and with a conveyor track running in the conveying direction of the bricks, onto which the pallets brought in from the side are moved in a pre-grouped manner. With extrusion plants for the production of bricks is in front of the outgoing conveyor line for the Finished products such a transfer device used, by means of which a support pad made up of standardized pallets on the conveyor line is inserted under the bricks arriving there, the width of which is the corresponds to different overall lengths of the Ziegd-Ten produced in each case.

In DT-PS 1759141 such a device for transferring from brick moldings produced on an extrusion press in various widths described on pallets, with which laterally below the transfer track for the brick bricks stops for the laterally inserted pallets and one Arranged in the conveying direction of the briquettes running transport track for the pallets are, in particular on the one hand the pallets with a designed in the conveying direction Profiling are provided, in the recess of which the end of the transfer path for the bricks can intervene directly, and on the other hand the side below the transfer path arranged sections are adjustable by hand, whereby a grouping of side by side corresponding to the overall length of the bricks lying pallets is possible; further be on the side below the overfill track for the bricks, which are stationary and movable in height make the pallets pushed in up to the stops and afterwards on a driven one that transports the bricks in the conveying direction Roller conveyor implemented. In this known arrangement must therefore to the desired Pre-grouping of the pallets in one of the overall length of the brick bricks Overall width, especially the stops on the side, can be adjusted manually - and also the feed strips which are longitudinally adjustable at their ends; in addition, the laterally inserted pallets are often used when the system is in operation wedged between these adjustable stops and the following pallets, whereby considerable disruptions occur in the operational process.

It is now a device of the type described above for Transfer of bricks produced by means of an extrusion press onto pallets be created in which the pallets are already on their side feed track in the desired width - ie according to the corresponding dimensions of the goat moldings - pre-grouped, then already in this grouping on the one in the conveying direction running transport train implemented and finally in the outgoing conveyor line introduced under the bricks brought on the upper transfer lane will.

According to the invention, this is the case with such transfer devices for brick bricks in a simple and satisfactory manner achieved in that the side feed track for the pallets from two adjacent pallets There are sections at their connection point on the machine frame on both sides a stop is pivotally mounted, which both stops by means of, on the the outer section of the lateral feed path Pallets can be disengaged and after taking over the intended number - for example of two adjacent pallets - through the downstream track section in front of the following one Re-engage the pallet coulter, while the outer track section is stopped at the same time and that the relevant movement sequences are expediently programmed via a Switching system can be controlled automatically.

In a preferred embodiment of this transfer device are on the stationary machine frame at the end of the side feed track for the Pallets and several limit switches attached one behind the other at the beginning of the transport lane, on the arrival of the pre-grouped number of pallets, in each case depending of this number a certain limit switch - for example with two pallets of the in the second place arranged limit switch - is put into operation, with this Predefined group of pallets for the purpose of redirection to the transport track in the longitudinal center the same symmetrical position is stopped.

In the case of the transfer device designed according to the invention for Brick bricks on pallets can mainly be the number of grouped together Pallets automatically preselected using a selector switch in the programmed switching system - in particular without manual operation or other mechanical changes; In addition, the prepared pallet groups can be used without being jammed Control to the turnover point from the transverse feed to the longitudinal conveyance moves and there on the transport line running under the production line for the bricks implemented.

In the drawing, an embodiment of the invention.

according to constructed device for transferring bricks moldings on pallets in Fig. 1 in side view and in Fig. 2 with removed transfer train for the bricks in plan view of the grouping and transfer device for the pallets.

This transfer device is on the horizontal, frame-shaped r.Iaschinenrahmen 1 at a level below that running down from the extruder Production line of the bricks Z laterally one consisting of two bars Cross web 1a attached, in which the double-track supply line 10 for the pallets P is mounted with its two mutually closing sections 11 and 12; within of the inner section 12 of this feed track 10 - also under the production line - The first conveyor belt 20a is the one running in the conveying direction of the brick moldings Transport track 20 used, which by means of a drive motor 22 over two Eccentric disks 23-23 lowered below the level of the inner feed path 12 or something can be raised over the same; the second conveyor belt 20b of this Transport track 20 lies on the other side of inner feed track 12 in the conveying direction. The transfer path 7 now runs along over the transport path 20 for the pallets P the finished brick moldings Z running out of the extruder with the horizontal Section 30a and the slightly downward sloping section 30b followed by Beit sheet 31, which rests loosely on the horizontal conveyor chain 40, so that the brick moldings arriving on the inclined section 30a of the transfer path 30 Z is loaded from above onto the pallets P brought by the conveyor chain 40 and the same of the loaded pallets P are transferred.

The special grouped and relocating device according to the invention .for the pallets P has the following mode of action: first be on the outer section 11 of the lateral feed track 10, the pallets P on both, on the frame rails generally attached, latched stops 13 pushed close together; afterwards these Stops 13 notched, whereby the inner section 12 the supply track lO is cleared for the 1st / continuation of the pallets, and Both track sections 11 and 12 are in motion at the same conveying speed set and the number of preselected in the authoritative program switching Pallets P transferred from the outer track section 11 to the inner track section 12, after which the outer feed track 11 stopped again and the side stops 13 are latched again; the inner feed lane 12 is with the pallet group P is moved on by a certain width until the foremost pallet in the transport direction P the assigned limit switch automatically preselected in the grouping program - here the middle switch 16b - reaches and switches, causing you the movement the inner feed lane 12 is stopped; then by means of the drive motor 22 over two eccentric disks 23 the first conveyor belt 20a in the conveying direction the brick bricks Z running transport track 20 is raised, making the pallets P removed from the inner feed lane 12 and in the main transport direction Continued via the second conveyor belt 20b to the subsequent conveyor chain 40 will. Both conveyor belts 20a and 20b have the same conveyor speed, which is correspondingly larger than that of the two sections 30a and 30b of the transfer path 30 for the bricks Z and the transport chain 40 by means of which the Pallets P are pushed under the Beit plate 31 in the conveyor line; by this control of the running speed of the individual transport tracks 20 and 30 or the conveyor chain 40 are used when moving the prepared pallet groups P on the transport path 20 between the same resulting gaps and closed the pallet groups P pushed through in close succession and under the Beit plate 31 finally - fitted with the bricks Z - by means of the subsequent Roller track 41 abtranspcrtieri.
