Definitions

the invention relates to a device for chamfering plasterboard, in particular for simultaneously chamfering the transverse edges of two plasterboards lying one above the other.
gypsum plasterboards are produced in a continuous manufacturing process by forming a tub from a cardboard web of certain width, the edges of which are bent up, into which flowable gypsum pulp is distributed by a calibration roller, which is then passed through another cardboard, the so-called Back cardboard, covered and the upstanding edges of the first cardboard, the view side cardboard, are folded over the back cardboard and glued.
the resulting plasterboard strand is cut into pieces that can be up to 400 cm and longer.
the longitudinal edges of these gypsum plasterboard pieces are deformed into a cardboard-covered edge by means of corresponding lateral shaped pieces.
the transverse edges, which are created by dividing the strand into individual plates, are, however, rectangular and more or less rough.
gypsum plasterboard is generally carried out by processing panels of certain dimensions that can be used as a whole, for example, storey-high, so that there are only vertical longitudinal edge joints or horizontal longitudinal edge joints. In other cases, however, the processing of several gypsum plasterboards or pieces of gypsum plasterboard is required, which also have to be butted and filled with the transverse edges. Such right-angled transverse joints and panels with frayed cardboard edges cannot be filled in this way, they have to be prepared for the filling, which means that they have to be chamfered.
this chamfer can be produced by hand with a knife or, better, with a planer, but this is a lengthy job and the resulting chamfer can also be faulty, since the planer is guided by hand, especially if the Chamfer is performed by a layperson.
the delivery of the two plasterboard panels lying one above the other with their visible sides takes place by means of endless conveyor belts which are arranged in a corresponding machine frame in a synchronous manner while pressure is exerted on the plasterboard panel from above.
the plasterboard lies on a table-like frame.
a pair is arranged virtually stationary on one side of the machine frame or the plasterboard for its transverse edge pair, while the opposite pair, again consisting of two circular saws, is provided for the other pair of transverse edges of the plasterboard and from this can be moved away in order to be able to be set on plates of different lengths.
Each aggregate of the pairs consisting of a circular saw and drive motor can be pivoted, horizontally and vertically adjusted, including the pair of circular saws known as stationary. Fixed in this context is only meant to mean that only the non-"fixed” pair needs to be set up again when changing over to plates of different lengths.
the circular saw blades are driven electrically, pneumatically or hydraulically at adjustable speeds.
the circular saw blades are preferably those with fine teeth or saw blades with diamonds or hard metal.
the machine frame forms a large table-like receptacle, on which at least two plasterboard stack can be accommodated, with their usual dimensions occurring in practice.
the machine frame is designed and planned according to known mechanical engineering rules so that it can fulfill its task.
It consists of a frame that forms the table-like receptacle for the GKP in its upper area. B. by means of support rails 10, which can also be designed with low friction and which carry the GKP stable and safe.
Transport devices in the form of chains or belts 6 and 7 are arranged below the plane in which the GKP are located, and they grip the GKP stack from below.
Pressure rollers 8 and 9 are provided above the GKP and bring the GKP stack into engagement with the transport chains 6.
the transport chain 6 in the left half of FIG. 1 is coupled via a shaft 12 to the transport chain 7 in the right half of FIG. 1, so that only one side needs to be driven.
the pressure rollers 8, 9 run empty and are available in a suitable number, although only two of them are shown in FIG. 1.
the pressure rollers are mounted in a correspondingly designed frame or frame (not shown) which is equipped with devices for pressing the pressure rollers onto the upper 13 of the plates of the GKP stack.
the transport chains 6 and 7 grasp the lower plate 14 of the GKP stack 1 in frictional engagement, so that the GKP stack with adjustable speed z. B. is movable in the direction of arrow 2.
the two circular saw units of each pair 4 and 5 form an angle with one another which can be selected and which corresponds to the desired chamfer and the thickness of the plates 13 and 14 to be chamfered can also be adjusted.
the drive means 15 can be of an electrical, pneumatic or hydraulic type.
Each GKP stack is now transported by the transport devices on the machine frame in such a way that the actual, cardboard-covered longitudinal edges of the GKP are at right angles to the transport direction.
the cross edges of the GKP but parallel to the direction of transport and so that their cross edges, the left 17 and right 18 now protrude an adjustable amount laterally beyond the table-like receptacle.
transverse edges 17 and 18 projecting laterally beyond the table-like receptacle of the GKP stack are now in the engagement area of a pair of circular saw units, namely the pair of units 4 on the left side edge and the pair of units 5 on the right side edge (FIGS. 1 and 2).
this chamfering process is nearing its end, since the GKP stack moves in the direction of arrow 2.
the device Since, as described above, the device must be usable for GKP of all common lengths, which are between 250 and 600 cm, the machine frame, the transport device, the table-like receptacle and other machine parts must be designed in such a way that they can be adjusted to these lengths.
the transport chains 6 and 7 are driven via the shaft 12 only from one side.
the shaft 12 and other parts can be telescopic or foldable.
the table-like receptacle with the support rails 10, the devices carrying the pressure rollers 8 and 9 could be designed like scissors and be moved together, both from one side and from both sides.
the arrangement of the circular saw units 4 and 5 in the exemplary embodiment shown is such that the unit 4 is "stationary", while the other 5, as shown by the double arrow 19, can be moved towards and away from the GKP because it is assumed here that the device is adapted to different GKP lengths by "pushing" the device to the left.
Both pairs of circular saw units including the "stationary" pair 14, are universally adjustable. "Fixed location” is only intended to mean here that when the length of the GKP changes, only one pair, namely pair 5, needs to be set up again.
the GKP pair moves with its transverse edges past the fixed circular saw unit pairs 4 and 5 and is chamfered
the stack consisting only of two GKP according to the above description can be expanded to form a stack with an integer variety of GKP pairs, e.g. B. to a stack of 20 GKP, d. H. to a stack of 10 pairs or more.
the multiple stack would be fixed and the pairs of circular saw units 4 and 5 would be chamfered over the transverse edges or transverse edges.
the training could then be supplemented so that the pair of circular saw units chamfer one GKP pair both during the forward movement and the next pair above or below during the forth movement.
the circular saw aggregate pairs 4 and 5 are guided in rails in this embodiment, have drive motors for the back-and-forth movement and devices with which each pair 4 and 5 is raised or lowered by the amount of the thickness of the second plates after each course over the transverse edge before the next course begins. All of these operations could be program controlled. To reduce dust pollution, the circular saw units are equipped with suction devices.
the angle which the chamfers form on the two superimposed plates corresponds to the angle which the circular saw blades form with one another. They virtually represent the legs of the angle and the bisector 20 of the angle lies in the plane in which the GKPs lying one on top of the other touch with their viewing side boxes. Instead of the term “chamfering” or “chamfering”, the term “chamfering” or “chamfering” is also used.
