Definitions
- the present invention relates to a device for depositing plates.
- the plates should be individually transported by a transport device and be stacked on a storage level at least in pairs.
- the invention refers in particular to uncoated chip, OSB, MDF and other fiberboard.
- An important and particularly considered by the invention application is the handling of individual plates delivered from a plate making press when inserted in a turning device or in cooling compartments of a cooling device, for example, adesternwenders ordeigelwenders or adepaternosters.
- the cooling compartments run along a predetermined one Loop cyclically and transport the plates along a part of this Track to cool these.
- the invention is also directed to conceivable other situations in which two or more plates stacked after a single transport into small packages should be.
- GB 1179857 shows a top and side suction vacuum head for stacking with glass panes.
- EP 0709320 A shows a stacking device for electrical conductive and non-ferromagnetic lids, in particular of aluminum, in which by eddy current generation on the one hand and by a respective lid on a On the other hand, stack-vacuuming achieves accelerated stacking becomes.
- EP 1041029 A2 shows a stacking device for paper sheets, in which between The uppermost layers in the stack of air is sucked laterally to the stack to compact and avoid subsequent pressing.
- US 5492318 shows a stacking device for stacking sheets of paper, in which the uppermost Paper sheet through lateral suction of air accelerates to the stack surface is brought.
- the invention is based on the technical problem of a device and a method specify an efficient and reliable separation and superposition allow the plates on the storage level.
- a device for depositing thin wood-based panels with a transport device, which is designed to transport the plates individually to a storage level and store on the storage level and thereby at least in pairs lay on each other, characterized by a suction, which is designed for sucking the lower of the stacked plates and the plate deposited thereon through the lower plate, and, on the other hand, a method for laying thin wood-based panels using the above apparatus and the steps of transporting the panels to the depositing plane and depositing the panels on the depositing plane at least in pairs and sucking the lower and adjacent ones of the superposed panels, those on the lower panel lying plate is sucked through the lower plate and thus held.
- the invention is based on the recognition that it is precisely in thin wood-based panels can lead to significant problems, if one when stacking
- the plates between the plates remaining air layer not fast and efficient is reduced. Due to the relatively low weight of the thin plates remain these on the air layer and thus each other lubricious and can be very light slip against each other. A secure positioning is not or only for the lowest plate possible.
- the storage level in the Invention may also be oblique, so do not necessarily lie horizontally got to. But even with inclined storage levels can be very easy as a result of slipping plates in the disk pack give problems.
- the inventors have found that thin wood-based panels a certain Having residual permeability to air, so that when generating a vacuum under the lowest plate a suction effect also through this plate for the overlying plate results.
- the next plate lying on the lowest plate So it can be sucked through the bottom plate, bringing both plates effectively positioned and in particular at least in places without remaining Air layer can be brought into contact with each other to a sufficient Stiction between the plates build up.
- the invention is directed only to such thin plates, the show sufficient air permeability, specifically on thin wooden boards with a porosity remaining between the fibers, chips or strips.
- the invention also in relation to the Positioning of the third lowest plate, so in particular the top plate in one Triplet, lets run. Even through two plates can be at sufficiently strong vacuum to achieve a suitable suction effect for this third plate.
- the invention is therefore directed in particular to the juxtaposition of two or three plates.
- the transport path in particular a constructed with transport belt or rollers track delivered become.
- the transport device in this case, be the one who puts the plates on top of each other. She can, however, the plates to one transport another transport device, which takes over this task.
- This other transport means may for example be a roller and preferably a pair of rollers to transport the plates between the two roles be. The role or the pair of rolls may then place the plates in one for one previously on the storage level already stored plate appropriate height lead the storage level.
- the role or the pair of rollers can Raise plates from a transport level of the conveyor track slightly for this purpose.
- roller conveyor In the storage level itself can also be a driven roller conveyor provided be.
- This roller conveyor can also be non-driven, i. free-wheeling or braked Have roles. Between or under the roles can be a or several vacuum suction or suction devices may be provided.
- the storage plane is preferably positioned so as to be in a cyclical sequence in FIG Refrigeration compartments of the aforementioned cooling device is arranged, so that the plate packs can be formed in each case in the cooling compartments.
- the refrigerators can for example, by rake-like gripping arms of a star-shaped, egg-shaped or paternoster-typedewenders be delimited from each other.
- Such cooling devices are known per se and therefore need not be presented in detail become. The same applies to turning facilities with subjects for the plates, about one Turner.
- An arrangement of suction openings of the suction device is preferred in a relatively close to that in the direction of the transport direction to the storage level rear edge. This is the position of this edge in the dormant state the plates went out.
- the suction openings may preferably with respect to on the extension of the plates in the disc transport direction to the storage level be provided in the adjoining the third third.
- the plates experience, especially in this rear area an air cushion formation between the plates, so that the suction device here is particularly effective.
- Other intake openings outside this range are conceivable, but not provided in the preferred embodiment.
- At least two vacuum suction can be provided side by side, wherein a connecting line between the intake ports thereby substantially can lie parallel to the mentioned edge.
- the transport direction to the storage level may preferably be parallel to a Rotary axis of the turning or cooling device can be arranged. She can, however run perpendicular to it (where the transport direction and the axis of rotation is not have to cut).
- the figure shows a highly schematic side view of an inventive Contraption.
- roller conveyor the individual plates to a pair of rollers 2 with respect to the transport path superimposed Can transport roles.
- an extension 3 closes the roller transport path, which defines a storage level.
- rake tines 4 of adesternwenders Between each of the Roller axes of the roller conveyor 3 engage in the figure shown in section rake tines 4 of adesternwenders, between which horizontal and in the figure in Section shown cooling compartments are limited.
- the pair of rollers 2 subsequent plates already on the storage level Place lying panels.
- the pair of rollers 2 as shown in the figure, at the level of the roller conveyor 1, but slightly above the level of the following Alternatively, the pair of rollers 2 can be attached also be vertically movable. Then, the roller conveyor 1 and the storage level is on a common level. The pair of rollers 2 can then the second and the third plate on the already on the storage level lying (n) Place plate (s). In this case, packets are formed by three superimposed plates.
- vacuum cups 5 are mounted, one of which is shown in the figure is and another lies behind or in front of the drawing plane, being the connecting line between the two vacuum cups 5 parallel to the roller axes and is perpendicular to the drawing plane.
- the vacuum cups 5 point upwards Suction on, through which sucked the first bottom plate and but also the second record placed on it and even the third one sucked last plate so that these are in the area above the vacuum cups 5 sucked together and held each other by static friction.
- the plates can effectively braked and can be an uncontrolled slipping the plates in the refrigerators are prevented. If this once stable lie on one another, the stiction between the plates ensures that they, if thedesternwender the cooling compartment further transported upwards, also essentially remain stable.
- the vacuum cups 5 are vertically movable and can when entering the first Plate to be moved down to avoid causing a collision with the first plate. If the leading edge of the first plate has been moved over it, you can they are driven up to the first plate and subsequently the suck in the second and the third plate. Otherwise, they are preferably with one Sealing lip made of an elastic plastic.
- an unillustrated safety stop is provided, to which the plates can abut when the effect of the suction device 5 should not be enough.
