Definitions
- the present invention relates to a stacker for paper products, in particular with an ejector for ejecting a stack of products from the stacker.
- stackers are known and serve to promote a sponsored Stream of paper products to stack packages, these packages Have sub-packages rotated by 180 °.
- This can be done in a vertical Movable lifting plate can be provided in the direction of growth of the stack formed is lowered.
- this lifting plate rotatable about a vertical axis, so that by appropriate rotation the lifting plate is arranged by 180 ° offset arrangement of the partial stacks can.
- the stack formed on the lift plate has a predetermined height has been reached, it is removed from the stacker.
- this can done by an ejector that moves horizontally over the lifting plate the stack from the lifting plate to a further medium is pushed down.
- the Ejector in a position to the side of the lifting plate, so that it only in Ejection direction is moved. It is also possible that the stacks, e.g. with a gripper which can be removed from the stacker.
- stackers are used in continuously operating systems, both constructions have the disadvantage that in the event of malfunctions in the The stacker subordinate plant parts of the stacker as well the parts of the plant in front of it must be switched off. By a such shutdown will incur significant costs.
- the stacker according to the invention contains to form the product stack a lifting plate that is rotatable about a vertical axis and vertical Direction is movable.
- an ejector arm that can be moved parallel to the ejection direction and an ejector for ejecting a stack of products from the stacker provided, the pusher on the pusher arm perpendicular to Ejection direction is kept movable. It is the ejector an item that is capable of stacking products from the lift plate slide.
- the lifting plate can help reduce the friction of the product stack on their surface and / or to reduce the moment of inertia also have recesses and or slots.
- the ejector preferably extends when it extends in the region of the Lift plate is located, at least over the total height of a to be ejected Product stack.
- the ejector can in particular be one Act rod or a correspondingly dimensioned hollow profile.
- the ejector is preferred by moving the ejector arm and by moving the ejector on the ejector arm in one plane Movable parallel to the lifting plate, resulting in a low overall height results.
- the pusher is preferably in or out of the product supporting area of the lifting plate movable so that it can be used without Ejecting is not an obstacle.
- the ejector it is sufficient for the function of the ejector described above from that the ejector by moving the ejector arm from a Waiting position in a working position directly behind the product stack and is movable over the lifting plate.
- the ejector is perpendicular to the side edge of the lifting plate Ejection direction extendable so that it is before the actual ejection movement is not located above the lifting plate. This allows the waiting position of the ejector regardless of the size of the lift plate stacked products can be selected, so that basically no new hiring depending on the product size is necessary.
- the pusher arm basically, especially when the lift plate Has slots through which the pusher is movable, below the lifting plate can be arranged movably, is in a preferred Embodiment of the ejector arm in a plane above the lifting plate movable. This is a particularly simple construction possible, because then the lifting mechanism for the lifting plate under the lifting plate can be arranged without regard to the movement of the ejector arm to have to take.
- the ejector arm can run parallel to the direction of ejection any drive means, e.g. Electric motors.
- any drive means e.g. Electric motors.
- the movement of the ejector arm takes place however, by means of an actuating cylinder, which makes a simple but fast responsive drive is given.
- actuating cylinder which makes a simple but fast responsive drive is given.
- it can these are hydraulic or pneumatic actuating cylinders.
- the ejector arm is as Telescopic arm formed, at the extendable end of the ejector is attached.
- This embodiment has the advantage that in the waiting position the ejector arm is not in the area of the lifting plate or the removal area enough.
- the torsional forces can be applied to the ejector arm, by pushing the product stack with the ejector occur, are reduced. From this point of view, the Ejector arm about half the height of a typical product stack the lifting plate lowered for ejection.
- the rod of the actuating cylinder engages for moving the ejector on the extendable part of the telescopic arm on.
- a recess running parallel to the direction of ejection is provided, in the free end of the ejector facing the lifting plate is feasible. On the one hand this avoids that product in the lowest Position between the ejector and lifting plate on the other hand, lateral ejection of the ejector is prevented.
- another is parallel and ejectors movable perpendicular to the ejection direction are provided, which is in a direction opposite to the discharge direction of the first Ejector is movable.
- this can be another ejector also on an ejector arm that can be moved parallel to the ejection direction be held movable perpendicular to the direction of ejection.
- the ejectors are preferably arranged in relation to the lifting plate in such a way that product stack in two opposite directions from the lift plate are movable.
- a stacker can in normal operation, with no interference in the subordinate units occur how a stacker are operated according to the state of the art, in the product stack by means of an ejector to the downstream Units is transferred. Due to the possibility of both ejectors Moving perpendicular to the direction of ejection can occur in the event of malfunctions facilities downstream of the stacker, the one emitting in normal operation Ejector by movement perpendicular to its direction of ejection from the working position in front of the product-carrying part of the lifting plate in a waiting position and the other ejector from a waiting position in a working position in the area in front of or above the lifting plate be moved so that the further ejector product stack in one Eject direction opposite to the normal ejection direction. This ensures continuous operation of the upstream of the stacker Facilities.
- the product stack can be removed in two opposite directions, in the event of faults in one of the parts of the system downstream of the stacker with the respective ejector the product in the opposite direction to be able to eject. This is particularly advantageous if only a stacker for two alternatively operated, downstream of the stacker Processing units for product stacks is provided.
- a stacker has a lifting plate 10 and a base frame arranged next to it 12 on which two guide tubes 14 and 16 are attached, on which above the lifting plate 10, an ejector arm 18 with a dashed line only shown pusher 20 is movably guided.
- On the base frame 12 is a first actuating cylinder 22 for moving the ejector arm 18 attached along the guide tubes 14 and 16.
- the lifting plate 10 is movable in the vertical direction and is used for formation of a product stack 11 shown in broken lines in FIG. 1 upon delivery of products from the P direction successively lowered. For education of partial stacks offset by 180 °, the lifting plate 10 continues to be about a vertical axis between two rotated against each other by 180 ° Stack positions rotatable.
- the lifting plate 10 also has one along of a diameter extending recess 24 in the stacking positions the lifting plate 10 parallel to the guide tubes 14 and 16 runs.
- the ejector arm 18 is a telescopic arm with an extension in the Y direction Part 26 and a base part 28 formed with which the ejector arm is movably held on the guide tubes 14 and 16.
- the area of the ejector arm 18 is shown in more detail in FIGS. 2 and 3.
- the base part 28 has a base plate 30, which is attached to it by two, on the guide tubes 14 and 16 running guide blocks 32 and 34 is worn (Fig. 3).
- the guide tubes 14 and 16 are there in the guide blocks 32 and 34 by means of plain bearings, which are not shown are stored.
- An arm element 36 is also on the base plate 30 attached, at the pioneering of the guide blocks 32 and 34 End four rail bearings 38, 39, 40 and 41 are attached.
- the extendable part 26 which is formed by a U-profile, also has rails 42 and 44 parallel to the direction of the ejector arm on running in the rail bearings 38 and 40 or 39 and 41.
- Rail bearings 38, 39, 40 and 41 are roller bearings that are designed and arranged so that a tilting movement of the rails 42 and 44 and thus the extendable part 26 in the vertical direction not possible.
- the extendable part 26 of the telescopic arm held vertically movable to the guide tubes 16 so that it, like shown in Fig. 1, between a dashed line waiting position and a work or represented by solid lines Ejection position is reciprocable.
- a connecting plate 46 20 attached, which is formed by a hollow profile, being from the above the ejector arm arranged on the lifting plate hangs down.
- On the ejector 20 has a guide pin 48 at its lower end with which the ejector in the recess 24 of the lifting plate 10th is feasible.
- the ejector arm 18 is along the guide tubes 14 and 16 by means of of a first actuating cylinder 22, for which purpose the guide block 34 is movable a connecting element 50 with the output element of the actuating cylinder 22 connected is.
- This actuating cylinder 22 thus serves to eject one Product stack. (Fig. 3)
- the extendable part 26 of the ejector arm 18, and thus the one attached to it Ejector 20 is via a second actuating cylinder 52 in the Y direction, that is, in the direction of the ejector arm and perpendicular to the guide tubes 14 or 16, movable.
- the actuating cylinder 52 is one attached to the arm member 36 flange 54 and one on the Base plate 30 attached bracket 56 fixed to the ejector arm.
- the rod 58 of the actuating cylinder 52 is between two with the extendable part 26 connected blocks 60 and 62 held so that the extendable part 26 is movable by means of the rod 58.
- the rail bearings 38 to 41 are arranged so that the blocks 60 and 62 movable with the rod 58 between the rail bearings are and thus the extendable part 26 retracted as far as possible can be.
- the pusher arm 18 is in operation the end of the base frame that lies in the direction from the product is removed from the lifting plate 10.
- the extendable part 26 as shown in dashed lines in Fig. 1, in a retracted waiting position, in which he is outside of the area of the lifting plate carrying the stack 11 10 is located and thus does not hinder removal.
- the extendable part 26 is now fully extended via the actuating cylinder 52, so that the ejector with the guide pin 48 (Fig. 3) in front of the Recess 24 comes to rest.
- the ejector arm is then used for ejection by means of the actuating cylinder 22 in the ejection direction X, i.e. opposite the removal direction, moved against the product stack 11, the so is expelled.
- the ejector arm 18 with the ejector 20 can again be driven to the ejection position to after formation of the next Product stack to eject it again. Is an expulsion by means of the Ejector 20 is no longer necessary, the extendable part 26 of the the ejector 20, which is in the working position, by means of the Actuating cylinder 52 again in the waiting position shown in dashed lines in FIG. 1 withdrawn.
- FIG. 4 shows a second preferred embodiment of the invention, which differs essentially from the first embodiment distinguishes that the stacker a second, above the lifting plate 10 movable ejector arm 64 with a second, only shown in dashed lines Ejector 66 has.
- this second preferred Embodiment are therefore the same reference numerals and Terms for the same elements as in the first embodiment used. Construction and drive of the second ejector arm 64 with Ejectors 66 correspond to those of the ejector arm 18 with the ejector 22 in the first preferred embodiment.
- the pusher arm 64 is also guided on the guide tubes 14 and 16, but is by a 4 not visible second actuating cylinder in the direction of Guide tubes moved.
- the two ejector arms are on opposite sides Ends of the base frame 12. From here, depending on requirements, one the pusher 66 initially in a direction parallel to the pusher arm from a waiting position next to the lifting plate to an eject position driven in front of the lifting plate to then along the guide tubes 14 and 16 together with the whole ejector arm for the purpose of ejecting of a stack of products.
