    专利说明:

    The invention relates to a dispenser for dispensing a sheet-like flat product, in particular paper, with a housing that can be closed by a preferably pivotable cover, and at least one pivot lever arranged in the housing with which a reserve roll of the sheet-like
    Flat product can be transferred from a waiting position to a transfer position.
    Such a dispenser can be found, for example, in WO 2009/135241 by the applicant. In the paper dispenser shown there, a receiving space for a spare roll is provided in its upper area, which is arranged on a support rod with bearing pins protruding on both sides. The receiving space is accessible after the cover has been pivoted up and is limited by a narrow point so that the reserve roll can only fall down after a corresponding reduction in its diameter due to the consumption of paper. There it serves as a donation roll until it is used up and a new reserve roll can be refilled. When the dispenser roll is empty, paper is used from the reserve roll until it can pass through the bottleneck again. Various motion sequences take place.
    In connection with the waiting position of the reserve roll, a swivel lever is provided which takes over the reserve roll with a reduced diameter and releases it again at the bottom in the transfer position, so that it slides further into the dispensing position as a dispensing roll. The upward return is made by a spring. The dispensing position is determined by a removable support, on which the support rod rests after the dispenser roll has been emptied. The support is moved so that the empty support rod falls off when the swivel lever transfers the reserve roll to the transfer position. There are relatively frequent malfunctions, since the coordination of the spring force for the return of the empty pivot lever can cause problems. The spring must be strong enough to reliably pivot the empty swivel lever upwards and must be weak enough to pass through the only
    to be tensioned with the swivel lever loaded with the reduced spare roll.
    The invention has now set itself the task of avoiding these difficulties and achieves this in that the at least one pivot lever is coupled in movement to the cover of the housing so that when the cover is opened, the pivot lever moves from the transfer position to the waiting position
    is traceable.
    This eliminates the need for a return spring and makes the dispenser more reliable. Since the swivel lever only has to swivel back and forth once per spare roll, this can easily be made dependent on the opening movement of the lid, since the lid also pro in normal operation
    Reserve roll only needs to be opened and closed once.
    In a preferred embodiment it is provided that the cover and the pivot lever can be pivoted about axes parallel to one another. This facilitates the kinematic coupling, since a coupling element which brings about the return of the pivot lever is preferably between the cover and the pivot lever
    is arranged.
    In a further preferred embodiment, the coupling element is linearly displaceable, it preferably having a slot for the connection to the cover, in which a driver pin of the cover engages. The cover can have a central rotating part in the manner of a hub, of which the
    Driving pin protrudes parallel to the axis of rotation.
    In a further preferred embodiment, the coupling element has a hook-like end in which a driver pin of the pivot lever loosely engages. If the cover is opened, the coupling element pivots the pivot lever back up, where it remains in the waiting position for the next spare roll and is held by a locking lever that is dependent on the diameter reduction of the spare roll. If the cover is closed, the hook-like end detaches itself from the driving pin of the pivot lever and the coupling element moves “empty” into a lower end position. The hook-like end stays there and takes the
    The drive pin of the swivel lever opens as soon as the reduced spare roll starts
    is convicted below. The next time the lid is opened to refill a new spare roll, the coupling element takes the swivel lever back into the
    Waiting position with.
    The movement transmission between the pivot lever and a spring-loaded second pivot lever, by means of which the movement of a removable support for the dispensing roll or the empty support rod is controlled, also proceeds in a kinematically similar manner. In a preferred embodiment, it is provided here that the second pivot lever can be moved back and forth during the movement of the first pivot lever. This means that the second pivot lever has already reached its rest position at the end of the forward movement of the first pivot lever and remains in this rest position during the return movement of the first pivot lever, in which an ejection opening for the empty support rod is closed by the removable support. The ejection opening is only opened briefly when the reduced reserve roll is transferred to the transfer position, since the empty support rod must fall out during this time. When the new dispensing roll arrives in the dispensing position, the ejection opening is closed again, so it requires the back and forth movement of the second pivot lever during the transfer movement of the first pivot lever and the decoupling of the second pivot lever when returning the first
    Swivel lever.
    In a preferred embodiment, it is provided that the second pivot lever comprises a first guide contour and a second guide contour separate therefrom, the first pivot lever having the first guide contour during the movement to transfer the reserve roll from the waiting position to the transfer position and the first guide contour during the return movement into the starting position the
    second guide contour is scanned.
    The first guide contour is designed in such a way that the second pivot lever is moved back and forth in order to open and close the ejection opening and then there is a change to the second guide contour, which is then scanned
    second pivot lever issued no movement. The transition area between the
    Both guide contours preferably contains a ramp which causes a lateral deflection of a scanning element of the first pivot lever. The sensing element is formed in particular at the free end of a spring tongue of the first pivot lever, so that at the end of the second guide contour the return to the first guide contour is effected by the spring-back of the spring tongue
    is achieved.
    Another preferred embodiment provides that the first guide contour comprises at least one concave section and / or that the second
    Guide contour comprises at least one convex portion.
    In order to support the opened cover, it is furthermore preferably provided that the above-mentioned rotary part of the cover migrates along a curved support surface of the housing and preferably engages releasably in a latching recess of the support surface. A preferred embodiment provides that the curved support surface moves from an initial position associated with the closed position of the cover into an end position associated with the open position of the cover
    increases, and the latching recess is formed at the upper end.
    The invention will now be described with reference to the figures of the enclosed
    Drawings described in more detail, without being limited thereto.

    A dispenser for paper has in a housing 1 an upper receiving space for a reserve roll 2, which is accessible after a cover 10 has been pivoted up. The dispenser has in the side walls 20 opposing guide tracks in the form of grooves into which the end-projecting bearing pins 19 of a support rod 3 engage. As can be seen from FIG. 2, a full spare roll 2 fills the upper part of the dispenser housing 1 quite a bit. A bottleneck defines a waiting position for the reserve roll 2. In the lower part of the dispenser housing 1, a receiving space is provided for a dispensing roll, from which the paper web is drawn off, while it runs through a conveyor. The width of the receiving space is significantly smaller than the diameter of a reserve roll 2, preferably only about half of it, so that other components of the paper dispenser can be accommodated in the space saved in the lower part. In order to still be able to remove paper from the dispenser after the paper of the dispenser roll has been used up, a device, which is not explained in more detail, is provided which feeds the beginning of the paper of the reserve roll 2 to the conveyor device following the end of the dispenser roll 2, so that the paper web of the reserve roll is subsequently 2 is deducted. The reserve roll 2 initially remains in the
    Waiting position in the upper part until it can pass the narrow point 20.
    The diameter of the reserve roll 2 is detected by a pivotable locking element 31 which rests on one or both of the bearing journals 19 of the support rod 3 sliding or rolling in the grooves of the guide track 4 (FIGS. 10, 11). The locking element 31 extends above the first section of the guide track 4, which slopes slightly backwards, and is pivotably mounted. The locking element 31 is raised by the bearing pin 19 of the reserve roll 2 when it is inserted into the paper dispenser. The locking element 31 has a hook-like projecting control part on which a locking projection is formed (FIG. 10).
    Paper is first dispensed from the dispensing roll located in the lower dispensing position, the support rod of which rests with a bearing pin 19 on a pivoting bracket 27. If the paper of the dispensing roll is used up, then paper is picked up by the reserve roll 2 in the waiting position by means of a device (not shown) and dispensed. The takeover devices required for this are known in various designs and are part of the general state of the art, so that they do not have to be discussed in more detail here. For the
    Understanding the invention discussed here, they are not important.
    The delivery of the paper from the reserve roll 2 leads to a reduction in diameter and the support rod 3 approaches the area of the section of the guide track leading downwards until the bearing journals 19 of the support rod are inserted into a fork-shaped receptacle 16 of a first pivot lever 5 (Fig. 3) enter with a release at the end of the locking lever 31 (Fig. 10, 11). As a result, the locking lever 31 pivots down slightly and releases a latch for the first pivot lever 5, the one with the reduced reserve roll 2 about the axis 15 downwards
    pivots.
    10 and 11 each show both positions of the first pivot lever 5 in order to be able to show both the waiting position of the reserve roll 2 and its transfer position in one figure. It goes without saying that the first pivot lever is 5
    assigned to either the waiting position or the transfer position.
    The first pivot lever 5 carries a protruding parallel to its axis 15
    Driving pin 6.
    The cover 10 is arranged in the manner of a hub on a rotating part 11 which can be pivoted up about an axis 9 and which can be seen in FIGS. 2 to 5. The rotating part 11 is provided with a protruding cam 14 which, during the pivoting movement of the cover 10, moves upwards along an ascending curved support surface 21 of the side wall 20. The support surface 21 has a trough 22 at the upper end, in which the cam 14 is releasably locked when the cover 10 is pivoted up (Fig.
    2), so that the cover 10 does not close by itself, but is intentionally closed
    7725
    must become. In the support surface 21, further troughs 22 are preferably provided in order to define the closed position and a damping during
    Effect closing.
    A second driver pin 12 projects from the rotating part 11 parallel to the axis 9. The cover 10 or the rotating part 11 is kinematically connected to the first pivot lever 5 by means of a linearly pivotable coupling element 7. The coupling element 7 has on the one hand a slot 8 in which the second driver pin 12 is guided, and at the second end a hook 13 which the
    first driving pin 6 loosely grips.
    When the cover 10 is moved from the closed position, which can be seen above all in FIG. 4, into the open position (FIG. 5) in order to be able to insert a spare roll 2, the rotating part 11 and the coupling element 7 become the first The pivot lever is moved up because the hook 13 takes the driving pin 6 with it. If the position shown in FIG. 5 is reached, the locking lever 31 latches, as described above, near the pivoted-up fork-shaped receptacle 16 to the first pivot lever 5 and thereby holds it in the waiting position. When the reserve roll 2 is inserted (Fig. 5), the cover 10 is closed again and the coupling element 7 moves down again without taking the first pivot lever 5, since the hook 7 is without connection to the first driving pin 6, and the first pivot lever is held by the locking lever 31. The inserted full reserve roll 2 approaches the fork-shaped receptacle 16 as consumption increases.
    Fig. 3 shows the end position of the reserve roll 2 in the waiting position from which it is conveyed with the first pivot lever 5 down. This takes place when the cover 10 is closed, the driver pin 6 of the first pivot lever 5 entering the hook 13 of the coupling element 7 “waiting” there. Since a new reserve roll 2 can now be refilled, the cover 10 is opened and the coupling element 7 guides the first in the manner described above
    Swivel lever back up.
    4 shows a reduced reserve roll 2 in the dispensing position, which is somewhat spaced from the transfer position of the downwardly pivoted first pivot lever 5 and is defined by a removable support. The support closes an ejection opening 26 through which empty support rods 3 (FIG. 2) fall down from the dispensing position. The support is removed and returned by means of a second pivot lever 17, the movement of which is controlled as a function of the first pivot lever 5 and thus indirectly via the movement of the cover 10. Details on this are given in more detail with reference to FIGS. 6 to 9
    explained.
    Fig. 6 shows the waiting position of the first pivot lever 5. The pivot lever 5 is provided with a spring tongue 23, at the free end of which a scanning element 24 protrudes laterally. In the waiting position, the scanning element 24 rests against a second pivot lever 17, the axis 18 of which lies parallel to the pivot axis 15 of the first pivot lever 5. The second pivot lever 17 is provided with a tab 27 at the end remote from its pivot axis 18, which in the dispensing position closes an ejection opening 26 at the lower end of the guide track and forms the removable support for the support rod 3 of the reduced reserve roll 2. The second pivot lever 17 is spring-loaded into the position shown in FIG. 6 and in particular is provided with a body spring which
    is supported on the side wall 20 of the housing 1.
    A three-dimensional guide is formed on the second pivot lever 17, which includes a first guide contour 28 and, starting from the position shown in FIG. 6, reduces its distance from the axis 15 of the first pivot lever 5. The first guide contour 28 ends at an edge that lies in the transition area to the second guide contour 29. If a reduced reserve roll 2 has now entered the fork-like receptacle 16 in the waiting position, and the locking lever 31 has released the first pivot lever 5, the first pivot lever 5 moves down under the weight of the reduced reserve roll, the sensing element 24 along the first Guide contour 28 migrates and displaces the second pivot lever 17 in the process. This moves the support surface out of the
    Ejection opening 26 and an empty support rod 3 lying thereon falls down.
    is locked.
    During the second pivoting of the first pivot lever 5 into the transfer position (Fig. 2), the scanning element 24 passes the edge in the transition to the second guide contour 29 and the second pivot lever 17 returns to its starting position, since in the transition area to the second guide contour 29 the distance to The pivot axis 15 of the first pivot lever 5 is greater than the first pivot lever 5. In this transfer position, the reduced reserve roll 2 is dispensed down into the dispensing position, in which the support rod 3 of the roll rests on the tabs 27 in the ejection opening 26 which has already been closed again. The roll is gradually used up and the first pivot lever 5 remains in the transfer position until the cover 10 is opened again to insert a new reserve roll 2. The first pivot lever 5 is pivoted upwards again via the coupling element 7 and the driver pin 6, the second
    The pivot lever 17 remains in the rest position.
    This is because the scanning element 24 hits a ramp 30 in the starting area of the second guide contour 29, which rises perpendicular to the first guide contour 28 and thus to the side. The scanning element 24 changes the contact surface on the second pivot lever 17 and the spring tongue 23 of the first pivot lever 5 bends out. After the ramp 30, the second guide contour 29 continues at an even distance from the pivot axis 15 of the first pivot lever 5 and ends at a second edge at the transition into the first guide contour 28 or the starting position in the waiting position of the first pivot lever 5 presses on the second pivot lever 17 along the second guide contour 29 essentially parallel to the axis of the second pivot lever 17,
    he remains, supported by the body spring 25, in the rest position until the paper of the
    The dispensing roll has been used up and the new, reduced reserve roll 2 is supplied via the first pivot lever 5, for which the first guide contour 28 is again scanned and the second pivot lever 17 is pivoted out again in order to eject the support rod 3. The two edges at the two transitions between the two guide contours 28, 29 each prevent one
    Distance of the spacer element 24.
