Definitions
- the invention relates to a method and a device for one-sided or two-sided lateral leveling of dried brick moldings and / or fired bricks transported by a processing machine with rotating planing tools (such as grinding wheels or milling cutters), with functional surfaces essentially assigned to the end face.
- rotating planing tools such as grinding wheels or milling cutters
- ERSA ⁇ ZBL ⁇ T (RULE 26) ground dimension (calibration dimension) does not correspond to the target dimension for this operation and is therefore to be regarded as "reduced stock” or even as “scrap". Even while the grinding work is in progress, there is a delay in the event of grinding wheel wear and the adjustment is only carried out after the manufacture of the minerals. The hourly or shift output on dimensionally stable, ie perfect bricks / brick moldings is therefore relatively low. In addition, the production of uneven bricks is uneconomical.
- the invention has for its object to provide an improved method and an improved device (machine) for one-sided or two-sided leveling of bricks / brick moldings, in which / which is guaranteed to work constantly while working quickly.
- dimensionally stable bricks are always produced, the dimensionally correct grinding (or milling) taking place independently of the finished dimension of the processed bricks (shaped articles), and gaps in the product sequence do not have a negative effect. If the grinding or milling tool is worn, the necessary adjustment (readjustment) takes place immediately, because according to the invention the machining front edge of the grinding wheel or the milling cutter is measured (measured) without contact and, if there is a deviation from the desired position, immediately into the desired position - Position position is brought - this is of great benefit at the beginning of each work after a tool change and / or after a maintenance or repair work.
- the invention is also distinguished from the prior art in that the leveling tool infeed movement is detected in a preferred and advantageous manner and also taken into account for the leveling tool wear measurement. Distributive developments of the invention result from the subclaims.
- the invention extends not only to the individual, defined claims, but also to their combinations.
- FIG. 1 is a side view of a grinding system according to the invention for leveling bricks / brick moldings on one or both sides,
- FIG. 2 shows a plan view of the same grinding system with a calibrating grinding station, two-sided (calibrating) lateral leveling being shown,
- FIG. 3 shows a plan view of a grinding system according to the invention with two calibrating grinding stations, two-step mode of operation being shown,
- FIG. 4 shows a side view of a grinding machine according to the invention, in which the bricks (moldings) to be ground are aligned in terms of height between a conveying device which can be dismantled as a whole (see cross hatching) and a pressing device which can be dismantled as a whole (see cross hatching) can be transported in tension through the grinding station (s),
- FIG. 6 shows a side view of a belt system which is used in the conveying device or in the conveying and pressing device
- Fig. 7 shows a cross section through the same belt system, wherein the working position spanning a brick to be leveled (molding) is shown.
- the invention can be gathered from both the claimed method and the claimed device claims and the graphic representation and their description.
- the machine according to the invention is designed as a grinding machine. However, the concept according to the invention can also be implemented on a milling machine. With this machine, either dried bricks Z or fired bricks Z are leveled on at least one side. Two-sided and thus calibrating processing is particularly preferred.
- the machine according to the invention works in a continuous process.
- the adjusting device J preferably consists of two lateral conveyor belts which run around in a vertical plane and whose front (inlet-side) ends diverge to form an inlet funnel (cf. FIG. 2).
- the bricks (moldings) Z which are centered when entering the machine, are gripped by a conveyor 2 and pressing device 3 arranged on a machine frame 1 - with a base (element) 1 a and two ends 1 b - and 3 in height in an adjusted position clamped and moved in such a position through at least one leveling station 4, 4 'and processed on at least one side, preferably on both sides, using leveling tools 5 designed as a grinding wheel or grinding head (similar to a milling head), in particular calibrated leveling.
- leveling tools 5 designed as a grinding wheel or grinding head (similar to a milling head), in particular calibrated leveling.
- 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 around an essentially horizontal axis. Your drive is numbered 5b. The entire functional unit (disk + drive) is arranged to be horizontally displaceable (see FIGS. 2 and 3).
- each tool unit including drive 5b is large - i.e. so far that the grinding wheels are easily accessible from their end face 5a - displaceable to the outside (in particular displaceable) This displaceability extends far beyond what is necessary for a length in the non-functional position
- the pianing tools 5, together with the drive 5b are moved so far outward that the pressure device 3 or the pressure device 3 plus the conveying device 2 is also occupied by the planer station (s) 4, 4 '
- the area is freely accessible and, if necessary, can be lifted upwards.
- Such maintenance and repair work can be carried out in the machine according to the invention at a piano station 4/4 'while the machine is running, ie when one or the other planner (s) 474 is in operation
- the pianier station 4 or 4 'required for the work step is delivered to the brick center plane (vertical plane of symmetry) to the required extent
- the leveling tools 5 of both pianing stations 4, 4 ' can be moved outward into a non-functional position and the tines (form lengths) Z can be transported through the machine without machining for the time of maintenance and repair work
- the positions of the free-end faces 5a of all the leveling tools 5 are continuously changed during the processing (leveling and / or calibration process) or at intervals preselected depending on wear by means of optical measuring device 6 , 6 'is monitored without contact, the actual position being compared with the target position and the result being converted into control pulses, which are coupled to the measuring device 6/6' with the associated leveling tool displacement actuator for control purposes.
- the Pla ⁇ ierwerkmaschinee 5 are, if necessary, ie if their face facing the brick to be processed (forml ⁇ ng) Z deviates from the target position 5a, while maintaining the machining process (grinding or milling process) automatically on the Target position set / tracked rt
- Each measuring device 6, 6 works with a light beam (bundle) 6a, which, during the leveling, runs in the area of each leveling leveling end face 5a and thereby outside the movement path of the brick / brick molding Z to be processed, perpendicular to the axis of rotation, and the circulation circuit as a secant as well as along the vertical plane passing through the "target dimension".
- Each light beam (bundle) 6a is assigned at least one light-receiving sensor, the light and shadow signal being used for position detection of the end face 5a and leveling tool tracking In a particularly preferred manner, at least two sensors (receiver cells) are present. As can be seen from FIG.
- each leveling tool 5 in a two-station machine it is possible to work in two stages for each leveling tool 5 on the basis of its own measuring devices (in particular so-called roughing and fine work).
- the measuring devices 6, 6 ' are each arranged in the area of the pressure device 3 (cf. FIG. 1) In order to ensure exact lateral leveling of the continuous bricks (molded articles) Z, the invention ensures that the bricks (molded lengths) Z remain in their lateral relative position specified by the adjusting device J even during the entire machining (grinding or milling).
- the machine's own transport system is preferably formed by two pressure-loaded endless belts made of flexible material, which are designed as conveyor and pressure belts 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 machining tool (s) 5 performing the machining, in particular grinding disc (s), run over a rail-like or plate-like flat abutment 9.
- the conveyor belt 2 and the pressure belt 3 are provided at the back with wedge grooves 7a, at least in the central cross-sectional area, into which wedge professional 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 wedge-shaped rollers 8 interact with the two lateral cross-sectional areas
- the endless strip material is designed as a so-called Kraftba ⁇ d and has splines 7a and Keii ⁇ ppe ⁇ 7b on the back
- the wedge professional rollers 8 are cushioned. 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.
- the “pressure band” 3 is preferably fastened to spring-loaded holders 11, which in turn are mounted on / in height-adjustable bearing elements 12.
- Each holder 11 carrying a printing tape end has a bearing arm 11 a which grips / supports between two spring elements 13, 14 which are provided at a distance and coaxially to one another.
- Pneumatic or hydraulic cylinders 13, 14 are advantageously provided as spring elements, of which the lower (13) is intended for slight lifting and the upper (14) for pressing and pressure compensation.
- the brick (shaped) transport system consisting of conveyor device 2 and pressing device 3, is light (simple and quickly) disassembled and, if necessary, provided interchangeably by a corresponding second copy.
- a driven conveyor belt 2 carrying the bricks (shaped articles) Z and a pressing or holding-down device 3 acting on the bricks (shaped articles) Z from above is preferably also designed as a belt construction, in each case as a complete “assembly unit” arranged on the machine frame 1 or a part assigned to it, in particular holder 11.
- These assembly units are marked in FIG. 4 by means of a crosshatch. They have elements 15, 16, 17 of a plug connection, namely those for adjustment / position fixing (position 15), locking means 16 (e.g. 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 is dismantled and replaced a replacement unit is replaced.
