Definitions
- the invention relates to a roof tile press with the in the preamble of Claim 1 specified features.
- a roof tile press known from WO96 / 32237 has on one divided anvil next to each other several sub-forms and on one in Stand up and down movable common pressure piece an equal number of upper forms that work with the lower forms.
- a loading device is attached to the side of the stand, which is used for roof tile blanks slabs to be pressed placed in the lower molds.
- An unloading device is attached to the side of the stand Press molded roof tile blanks from the lower mold. The chunks are brought up on a first roller conveyor and the roof tile blanks conveyed on a second roller conveyor.
- the loading device has guides on which a carriage with a suction lifting device runs, which picks up the slugs from the roller conveyor, into the open one Press between the upper molds and lower molds and the Put chunks in the lower molds.
- the removal device has a similar structure.
- the well-known roof tile press works with open forms. With open forms is worked with 20% to 50% excess material, depending on the type of roof tile. The excess material of the slug to be formed occurs laterally between the Upper form and the lower form, which is why the forms referred to as open forms become.
- Open forms are mainly used as a plaster cast forming roof tile. Due to the highly porous surface of the plaster and due to the water film that forms when the roof tile blank is formed the roof tile blank is sucked into the plaster mold from a chunk. In order to remove the roof tile blank, large release forces must therefore be of the order of 3000 to 5000 N can be overcome, many times over are higher than when working with closed forms. With one often used three-field press, in which three roof tile blanks in simultaneously three adjacent molds are pressed, the release forces are taken together three times as high.
- closed molds If you work with closed molds, the size of the chunks becomes like this dimensioned that at most 1% to 2% excess material is available.
- closed molds are made from a cast steel alloy sprayed with kerosene as a release agent. It is also closed Steel molds have been known to use ejectors for the roof tile blank, which with the frequently changing open plaster molds for cost reasons and because of the precise guidance of the ejector, which is hard to achieve in plaster molds have so far not been able to enforce.
- the robot needs so much mass on its arm that it can be used in modern Roof tile presses become too slow and slow. In order to achieve the necessary working speed, one would have to have a robot use only approx. 800 N load capacity. However, this can be used for roof tile blanks do not detach from plaster molds. The situation becomes particularly difficult when one considers multi-field roof tile presses, e.g. a three-field roof tile press, because the robot will even have a load capacity of around 9,000 N to 15,000 N ought to.
- roof tile presses with open forms have usually been used as turret presses or swivel beam presses, for example as in DE 43 44 636 C1.
- the lower molds are located in a turret press on a hexagonal drum, which can be moved up and down under a step Thrust piece is moved through and an obliquely upwards pointing loading station on one side of the press stand and one unloading station on the other side of the press stand goes through.
- a swivel bar instead of a hexagonal drum, which is between a correspondingly obliquely upward Loading station and an obliquely upward unloading station and panned.
- the loading device and the unloading device are in both Cases pivoted to move between the diagonally after Make the bottom mold pointing upwards and a horizontal conveyor belt can.
- the present invention has for its object to show a way how to make it easier to remove roof tile blanks from plaster molds, so that this is accessible for handling by a robot, especially in roof tile presses with multiple fields.
- the invention provides that for A separate drive removes the roof tile blanks from the lower molds is provided, which on the one hand can provide the high release force, which is a lot is higher than that for the subsequent transfer of the roof tile blanks is required, on the other hand, this high power is only achieved in a short way, because it's all about the roof tile blanks with the separate drive detach from the lower mold. Therefore, the dedicated one Drive, although powerful, is relatively small and light be so that it does not make the unloading device undesirably sluggish.
- the invention thus creates the prerequisite for this as an unloading device a versatile and sufficiently fast hand-held
- articulated arm robots with the usual drives of an articulated arm only the roof tile blanks detached from the lower molds on a conveyor, e.g. B. must be transferred to a roller or belt conveyor and the one on top of his articulated arm due to the extra on detaching specialized drive, not too heavily loaded because of this arranged drive only needs a short stroke and therefore small and can be easily formed.
- the usual drives for moving the articulated arm do not have to provide the transfer force, but only a transport task have, they can also be designed slightly, so that the inertia the robot can be kept relatively low.
- the invention is suitable for different roof tile presses, for anvil presses, for turret presses, also for swing beam presses, the use of an articulated arm robot because of its versatility and mobility is particularly advantageous for turret presses.
- the unloading device expediently has lifting devices that operate with suction on, e.g. one equipped with air intake openings or suction cups, from a knife box for trimming the edges of the roof tile blank equipped suction plate, which can be raised and lowered on a carrier is.
- This carrier can be a plate which is at the top an articulated arm of a robot is attached.
- a lifting device working with suction is particularly suitable for an anvil press, which is attached to a sled, which on guides is movable, directly or indirectly on the stand of the roof tile press are attached.
- the lifting device can be moved from this carriage to the one in the Roof tile blank lying below the mold, suck it out loosen the form, lift it a short distance, then lengthen it with the sledge the guides move up to a conveyor and put it down there again.
- the lifting device is preferably by one or more pressure medium cylinders actuated, in particular by hydraulic cylinders, because these are compact Dimensions and low weight allow high forces for short strokes. It but it is also possible to use electromechanical drives to the roof tile blanks can be removed from its lower mold with a short stroke, e.g. electric motor driven spindles, cams, eccentrics, toggle levers and the like for the transmission of high forces during short strokes suitable gear elements.
- Toggle lever drives generate close to the according to the toggle lever characteristics Extended position of the toggle lever high forces with low strokes. You can do that by taking advantage of the lifting device and its support connects one or two pairs of toggle levers and these at the knee joint by one Pressure cylinder connects.
- Another option is power cylinders to use, which work according to the wedge lever principle and depending on the design overcome a large stroke (the attack stroke) in a short time and in a previous one or subsequent power stroke a much higher force than a conventional pressure medium cylinder with the same piston diameter within one can transmit short distance.
- the power cylinder is preferred pneumatically operated, but could also be driven hydraulically or by a spindle be. For lifting, transferring and depositing the roof tile blank only a small suction force is required, which depends on the weight of the roof tile blank is determined.
- An embodiment of the invention is particularly preferred in which the peeling force is applied in that the effecting the stroke of the lifting device separate drive elements not between the lifting device and their carrier, but between the lifting device and the carrier of the lower molds are effective so that the lifting device is pushed away from the lower molds becomes.
- the easiest way to do this is to use the lifting device, e.g. on the suction plate for the roof tile blanks, several short-stroke pressure medium cylinders are provided, preferably at the four outer corners the lifting device one each, the piston rods against the carrier of the lower molds are directed and pressed against it to detach it cause.
- the roof tile press according to Figure 1 to Figure 3 has one on a floor 1 anchored stand 2, in which a pressure piece 3 in the form of a horizontal Beam slidably mounted up and down and for this purpose with its Ends in vertical guide means 4 of the stand is guided.
- a drive unit 5 is provided at the top in the stand 2, which acts on the pressure piece 3 via a toggle lever arrangement 6.
- the drive unit 5 can be a hydraulic cylinder or an electric motor, which acts on the toggle lever arrangement 6 by means of a spindle.
- Each upper mold 7 is assigned a lower mold 17, which is on a stationary in the Stand 2 arranged anvil 15 is clamped.
- the anvils can be individually be anchored in the stand 2, but can also be combined to form a structural unit be, 17 recesses 16 being present between the subforms are located between the anvils 15 or in which a unitary assembly forming anvil 15 downward, as shown in Figure 2, so that when closing the molds excess material from the molds on all sides step out, fall off and can be transported away, as in the WO 96/32237.
- the lower molds 17 are located directly below the upper molds 7 preferably open plaster molds; instead of the open plaster molds can e.g. B. also open forms can be used with a rubber blanket are covered.
- a roller conveyor 18 is provided on one side of the roof tile press, on which piece 19 of the still moist ceramic material to be molded be promoted. Instead of the roller conveyor 18, a Belt conveyors are used. The chunks 19 are usually thereby formed that they are cut from a strand emerging from an extruder become.
- the suction plate 21 is liftable and lowerable on the slide 20 and is used to on the Roller conveyor 18 sucked up batches 19, from the roller conveyor 18 take off, along the guide rods 10 and 14 in the roof tile press to be transported to a position vertically above the lower molds 17 and in to file them. Since four sub-molds 17 are provided, four chunks are made 19 simultaneously taken up side by side and placed in the lower molds 17. The carriage 20 then moves back into the position shown in FIG pick up next batches 19.
- the pressure piece 3 is then moved downwards to press the upper molds 7 against the lower molds 17 and the molds thereby closing, whereby the lumps are reshaped and the excess Material of the bats emerges laterally from the open forms and falls off.
- the pressure piece 3 with the upper molds 7 is raised and a carriage 22 provided on the other side of the stand 2, which is displaceable on the same guide rods 10 and 14 moves into the open roof tile press and is positioned over the lower molds 17.
- a knife box 23 which is open at the bottom is suspended on the carriage 22, in which suction cups or suction plates, not shown, are arranged are.
- the circumference of the knife box 23 is determined by a frame-shaped knife formed, which determines the size of the roof tile blanks to be pressed and serves to trim the roof tile blanks and on their edge through the Press to separate ridges formed.
- the knife box 23 is together with the suction cups or suction plates, which he surrounds by means of toggle levers 24, which by a pressure medium cylinder, e.g. an air cylinder 25 are actuated, exactly vertically up and down, the lower end position by stops 26 is determined.
- the toggle 24 by pressing the Air cylinder 25 bent and the sucked roof tile blanks 28 exactly lifted vertically upwards from the lower molds 17; then they will join the carriage 22 moved out of the roof tile press into the one on the left Side of the stand 2 shown position (see Figures 1 and 3) and on a roller conveyor 27 provided there, which the roof tile blanks 28 promotes. 1 and 3, the carriage 22 is shown in two positions, once exactly over the lower molds 17 and once in its position above the roller conveyor 27. There are not two such slides 22 in a row intended.
- the recesses 9 in the pressure piece 3 are dimensioned so that the upper molds 7 can be placed on the lower molds 17 without the guide rods 10, 14 abut on the underside of the pressure piece 3.
- the basic structure of a turret press for roof tiles is, for example known from DE 44 01 506 A1, DE 44 01 507 A1 and from EP 0 434 863 B1, which is referred to for further details.
- the one in the figures 4 to 9 shown turret press has a hexagonal drum 29, which is rotatably mounted about a horizontal axis in a stand 2.
- the at least one associated Upper mold 7 or the several associated upper molds 7 are located on the underside of a pressure piece 3, which is above the drum 29 and slidably mounted in the stand 2 and driven by a drive unit 5 is.
- the vertical guidance of the pressure piece 3, the drive unit 5 and the gear elements provided between them can be more conventional Be construction and are therefore not shown.
- the drive can either hydraulically directly or via toggle lever or electromotively via toggle lever or via a spindle.
- a horizontal roller conveyor 18 is provided on one side of the stand 2, on which batches 19 are conveyed, from which roof tile blanks to be pressed.
- a further horizontal conveyor 27 is provided, which is designed as a belt conveyor is and serves to remove the pressed roof tile blanks 28.
- the two horizontal conveyors 18 and 27 can be of a known type. Instead of of the roller conveyor 18, a belt conveyor can be provided instead of the belt conveyor 27 also a roller conveyor.
- a robot 31 which serves to remove the roof tile blanks 28 from the drum 29 and to put on the horizontal conveyor 27.
- the robot 31 is around a conventional articulated arm robot, the arms 32, 33, 34 of different, horizontally or vertically oriented axes are pivotable. Therefore, the outermost arm 34 can perform a spatial movement with multiple degrees of freedom accomplish.
- a plate Carrier 35 attached, which carries a lifting device 36 which on Bars 37 is slidably mounted, which extend at right angles from the carrier 35, so that the distance between the lifting device 36 and the carrier 35th is changeable.
- Coil springs 38 which surround the rods 37 are between the carrier 35 and the lifting device 36 and press the lifting device 36 away from the carrier 35, at most up to one, not shown Attack.
- the lifting device 36 has one or more suction plates 21, which form a knife case 23 from a projecting edge 39 are surrounded.
- the lifting device 36 has a multiple function: your suction plate 11, 21 sucks the roof tile blanks 28 and therefore has one of the shape of the roof tile blank 28 adapted surface contour.
- the knife box 23 carries out the necessary trimming work on the roof tile blank with its edge 39 28 through before it is removed from the lower mold 17.
- At the four Corners of the lifting device 36 of which only two corners are shown one hydraulic cylinder 41 each is attached. Their piston rods 42 run parallel to the rods 37 and can be advanced beyond the edge 39.
- the turret press works as follows:
- the drum 29 can be rotated in steps of 60 °. There is always one in the rest position the drum surfaces 30 opposite the pressure piece 3, so that the upper molds 7th each have the same number of sub-molds 17.
- batches 19 are transported by a conventional loading device placed on the lower molds 17, which are inclined upwards on the facing drum surface 30a in the vicinity of the roller conveyor 18.
- the structure of the loading device can be selected and is conventional not part of the invention, so the loading device in this example is not is shown.
- the roof tile blank 28 By turning on of the drum 29 by 60 °, the roof tile blank 28 reaches position 30b, in which the drum surface 30 carrying it adjacent to the horizontal conveyor 27 is and points obliquely upwards.
- the robot 31 sets in this position 30b the lifting device 36 on the roof tile blank 28, which the knife box 23 forming edges 39 trim the roof tile blank 28 and the resulting waste pieces 43 fall down.
- a suction unit not shown the roof tile blank 28 to the suction plate 21 in the lifting device 36 sucked in.
- the piston rods 42 of the hydraulic cylinders 41 are advanced, hit the platen 17a of the lower molds 17 and press the lifting device 36 together with its suction plate 21 away from it, so that the roof tile blanks 28 are detached from their lower molds 17 (FIG. 7).
- the robot 31 moves the carrier 35 together with the lifting device 36 away from the platen 17a of the drum 29 and transfers the Roof tile blank 28 to the horizontal conveyor 27, on which he deposits it.
- the helical springs 38 push the lifting device 36 back into its Starting position ( Figure 5) back and the piston rods 42 are retracted ( Figure 9).
- the robot 31 moves the lifting device 36 back into hers Position in which they the next roof tile or tiles 28 in the drum position 30b can take over.
- Loading, pressing and unloading take place in time with the turret press, i.e. six times in the course of a drum revolution.
- FIGS. 4 to 9 by means of hydraulic cylinders 41, which are supported on the platen 17a of the lower molds, can also with an anvil press, as shown in Figures 1 to 3, come into use.
