Definitions
- the invention relates to a method for simultaneous chamfering the transverse edges of two plasterboard panels lying one above the other.
- plasterboard in a continuous Manufacturing processes are made in that from a Cardboard web of certain width, the edges of which are bent up, a tub is formed into the flowable gypsum pulp a calibration roller is distributed, which is then by a another box, the so-called back box, covered and the raised edges of the first box, the View side boxes, folded over the back box and be glued.
- the resulting plasterboard strand is cut into pieces that are up to 400 cm and longer can.
- the longitudinal edges of these plasterboard pieces will be through corresponding side fittings to a cardboard-coated edge deformed.
- the transverse edges created by the Division of the strand into individual plates are created meanwhile rectangular and more or less rough.
- Gypsum plasterboard is generally processed so that you can process plates of certain dimensions, which as Whole can be applied, for example floor-to-ceiling are so that there are only vertical longitudinal edge joints or result in horizontal longitudinal edge joints. In other cases is, however, the processing of several plasterboard or plasterboard pieces required, which also with the Cross edges must be butted and filled. Such right-angled transverse joints and panels with frayed Cardboard edges cannot be done in this way fill, they must be prepared for the filler , that means they have to be chamfered become.
- this chamfer can be done by hand with a Knives or better be made with a planer, however this is a tedious job and the resultant one Chamfering can also, since the planer is guided by hand be faulty, especially if the chamfer by a layperson is carried out.
- Cardboard plates, chamfer, tools and Methods are in Hanusch, "Gipskartonplatten", 1978, page 38 ff. described.
- US-A-4 969 380 discloses an apparatus and method to produce a longer V-shaped recess in Plasterboard and uses a saw with two successive saw blades as well as the US-A-3 910 170.
- GB-A-2 006 107 discloses a sawing device for processing timber. The facility described here enables the cutting of wood under relatively steep Angle after a conveyor belt if the lumber is slightly thinner than the saw blade diameter is and enables the use of the full blade diameter for cutting if that Lumber is relatively thick.
- EP-A-0 333 994 discloses a method for chamfering the transverse edges of two at the same time superimposed plates.
- This task is solved by a procedure for simultaneous chamfering of the transverse edges (17, 18) of two superimposed plasterboard in a process for Production of plasterboard, the plasterboard (13,14) with their view sides on top of each other and each Cross edge with two each at an angle to each other and staggered driven circular saws into engagement come, each with a transverse edge of a plasterboard a circular saw comes into engagement.
- the view sides are preferably fed in superimposed two plasterboard panels by means of endless Conveyor belts in a corresponding machine frame are arranged in synchronous rotation, while from above on the Plasterboard pressure is exerted.
- the plasterboard lie on a table-like frame.
- Each unit consisting of a circular saw and drive motor Pairs can be swiveled, adjusted horizontally and vertically, also the pair of circular saws known as stationary. Festival in this context is only meant to mean that when the transition to Plates of different length only the not "stationary" pair new needs to be set up.
- the circular saw blades are driven electrically or pneumatically or hydraulically with adjustable speed.
- the circular saw blades are preferably those with fine teeth or around with diamonds or Carbide-tipped saw blades.
- the machine frame forms a large table-like holder, find a place on the at least two plasterboard stacks can with their usual in practice Dimensions.
- the machine frame is based on known mechanical engineering Rules constructed and planned so that it does its job can meet.
- Pressure rollers 8 and 9 are provided above the GKP Engage the GKP stack with the transport chains 6.
- the transport chain 6 in the left half of FIG. 1 is over a shaft 12 with the transport chain 7 in the right half 1 coupled so that only one side is driven are needed.
- the pressure rollers 8, 9 run empty and are in suitable number, although in Fig. 1 only two of them are shown.
- the pressure rollers are in a corresponding designed frame or frame (not shown) stored, with devices for pressing the pressure rollers on the top 13 of the plates of the GKP stack.
- the transport device If the transport device is now started, record it the transport chains 6 and 7 the lower plate 14 of the GKP stack 1 in frictional engagement, so that the GKP stack with adjustable speed z. B. in the direction of arrow 2 is movable.
- the drive means 15 can be electrical, pneumatic or be hydraulic.
- Each GKP stack is now of the Transport equipment transported on the machine frame, that the actual, cardboard-coated longitudinal edges of the GKP lie at right angles to the direction of transport.
- the transverse edges of the GKP but parallel to the direction of transport and so that their Transverse edges, the left 17 and right 18 now an adjustable Extend the amount laterally beyond the table-like holder.
- the GKP stack on the machine frame by means of Transport devices are set in motion and are the Aggregate pairs 4 and 5 in a corresponding and correct manner the lateral transverse edges 17 and 18 of the GKP stack aligned, these rangers are chamfered as in Fig. 3, when the circular saw units are started.
- the device for GKP of all common Lengths between 250 and 600 cm can be used must, the machine frame, the transport device, the table-like holder and other machine parts designed so be that they can be adjusted to these lengths.
- the transport chains 6 and 7 are driven via the shaft 12 only from one side. In such a case you can the shaft 12 and other parts are telescopic or foldable his.
- the table-like receptacle with the support rails 10, the the pressure rollers 8 and 9 supporting devices could be designed like scissors and can be moved together both from one side and from both sides.
- the arrangement of the circular saw units 4 and 5 is in the illustrated embodiment so that the Unit 4 is "stationary", while the other 5 is like that Double arrow 19 points towards and away from the GKP is movable because it is assumed here that the adaptation of the Device to different GKP lengths "pushing" the device to the left.
- Both pairs of circular saw units are universally adjustable. "Local festival” here only means that when changing the length of the GKP only one pair, namely the Couple 5 needs to be refurbished.
- the above description consists of two GKP stacks of one Expanded stacks with an integer variety of GKP pairs its z. B. to a stack of 20 GKP, d. H. to a stack with 10 pairs or more.
- the training could then continue to work rationally are supplemented so that the circular saw unit pairs both at chamfer a pair of GKP during the forward movement and during the forth movement the next pair above or below.
- the pairs of circular saw units 4 and 5 are in this Design guided in rails, have drive motor for the Back and forth movement as well as facilities with which a every pair 4 and 5 after each course over the transverse edge around the Amount of the thickness of two plates is raised or lowered before the next course begins. All of these processes could be program controlled. To reduce dust pollution the circular saw units are equipped with suction devices.
- each pair of circular saws (4,5) a suction device is assigned.
- the Circular saw blades (16) are preferably finely serrated or with Set with diamonds or hard metal.
