Definitions
- the invention relates to a machine for the lateral processing of building blocks or the like., In particular dried brick moldings or fired bricks, which are transported in an adjusted and clamped height by at least one processing station with a lateral tool arrangement.
- the invention is therefore based on the object of providing an improved machine for lateral block processing, in particular lateral leveling of bricks or brick moldings, in which the objects to be processed are securely fixed in a once-adjusted position and can be transported immovably in such a position by at least one processing station are.
- an exact lateral position of the endless belt as well as an exact flat position of the strand acting on the object to be processed is achieved in the area of the processing station.
- This machine can be designed as a grinding machine and / or milling machine. It is preferably for the lateral processing of dried Brick moldings and / or fired bricks provided - of course, other products of the building materials industry, for example pumice stones, refractory stems (firebricks), tiles and the like can also be processed with it
- FIG. 1 is a side view of a machine according to the invention for the lateral processing of building blocks or the like, preferably a grinding machine in which the objects to be ground, in particular dried bricks or bricks, are transported in height after being aligned laterally between a conveying device and a pressing device by at least one processing station,
- FIG. 2 is a sectional view of a height-adjustable and sprung holder for the pressing device ends
- FIG 3 shows a side view of a belt system which is used in the conveying device or in the conveying and pressing device
- Fig. 4 shows a cross section through the same belt system, with a clamping working position for a brick to be leveled (molded article).
- the machine according to the invention for lateral processing of building blocks or the like is preferably designed as a grinding machine.
- the concept according to the invention can also be implemented on a milling machine. With this machine in the flat brick production either dried green bricks Z or Z burnt bricks are leveled at least one side *. Two-sided and thus calibrating processing is particularly preferred.
- the machine according to the invention works in a continuous process.
- It has a machine inlet formed by an adjusting device J, which automatically brings (centered) the objects to be processed, in particular to be ground (such as bricks or brick moldings Z) into a position required for processing.
- the centers (form lengths) Z which are centered when entering the machine's own transport system, are grasped by the conveying device 2 and pressing device 3 arranged on a machine frame 1 - with bases (element) 1 a and both ends of stands 1 b - and in an adjusted position clamped to a high degree and moved in such a position through at least one pianier station 4 and, on at least one side, preferably on both sides, machined, in particular calibrated, leveled, using a leveling tool 5 designed as a grinding wheel or grinding head (similar to a milling head)
- the leveling tools (such as grinding wheels or milling cutters) 5 are provided with functional surfaces which are essentially assigned to their end face 5a. They rotate about an essentially horizontal axis. Their drive is numbered 5b. The entire functional unit (wheel + drive) is arranged to be horizontally displaceable net
- a non-contact measuring device is preferably present which detects the machining end face 5a of each panning tool 5 and its signals for automatic leveling tool tracking can be used
- the machine's own transport system is preferably formed by two pressure-loaded endless belts made of flexible material which are designed as a conveyor belt and pressure belt 2, 3 and which are positively guided in the lateral position by means of at least one centering tongue and groove connection - in particular a keyway-keyway connection at least in the area of the tion-carrying planing tools (s) 5, in particular grinding wheel (s), run over a rail-like or plate-like flat abutment 9.
- the conveyor belt 2 and the pressure belt 3 are provided on the back at least in the central cross-sectional area with splines 7a, in which spline rollers 8, as centering rollers, engage.
- two slide strips 9 are preferably provided, which act on the two side regions.
- at least one slide bar 9 supports the central cross-sectional area and the spline rollers 8 interact with the two lateral cross-sectional areas.
- the endless band material is designed as a so-called force band and has splines 7a and V-ribs 7b on the back.
- the spline rollers 8 are spring loaded. 6 and 7, the spring elements shown symbolically are numbered 10.
- each spline roller bearing is cushioned by means of a spring assembly and is arranged in a guided manner at the same time - additional guide elements are saved.
- the pressing device 3 (in particular a so-called pressure belt 3) can be adjusted in the position relative to the conveyor belt 2 - and is accordingly arranged in a height-adjustable manner - and is supported in a spring-loaded manner.
- conveyor belt 2 and pressing or holding-down device 3 are each detachably arranged as a complete “assembly unit” on the machine frame 1 or a part associated with it, in particular holder 11.
- These assembly units are marked in FIG. 1 by means of cross hatching. They have elements 15, 16, 17 of a plug connection, namely those for adjustment / position fixing (position 15), locking means 16 (eg screws) and an electric coupling 17.
- the downtime in the event of maintenance and / or repair work can be reduced to a minimum if the device (s) 2/3 present in the machine are dismantled and is replaced by a replacement unit.
