    专利说明:

    The invention relates to a handling device or molding machine, in particular injection molding machine, with a control or regulating unit for controlling or regulating the handling device or forming machine and an operating device connected to the control or regulating unit, wherein the operating device a housing, a movable relative to the housing in a movement space Operating element and an adjusting device for adjusting the operating element relative to the housing.
    In handling devices and in molding machines, especially injection molding machines, transfer molding or pressing, the operating options have been constantly improved and modernized in recent decades. Since an operator stays on the operating device for often rather long periods of time, an essential aspect in recent years has been above all the increase in user-friendliness and improved ergonomics in operating the shaping machine.
    An example of such an improved control unit is apparent from the applicant's own AT 504 642 B1, according to the screen brightness in addition to the position of the screen can be changed. A problem with such adjustable screens is that an operator can pinch his fingers between the control and the housing upon movement of the control to injure himself. It is also possible that objects come in this area and thus damage occurs.
    The object of the present invention is therefore to provide a comparison with the prior art improved molding machine. In particular, injuries and damage should be excluded if possible.
    This is achieved by a forming machine having the features of claim 1. Accordingly, a safety device is provided, by which either the movement space can be covered or by which a movement of the operating element in the movement space can be monitored and stopped or by the
    Operating element of the adjusting device can be decoupled. According to the first possibility, therefore, the movement space is covered, whereby nothing more can get into the movement space. According to the second variant, the movement space is monitored and, if necessary, stopped accordingly. According to the third variant, the transmission of motion between the control element and adjusting device, for example in the event of an overload, can be easily decoupled.
    There are basically two possible approaches to how the security device itself is designed. On the one hand, it can be designed mechanically and, on the other hand, electronically. Of course, mixed variants are also conceivable.
    In the mechanical variant, it is preferably provided that it is designed as a preferably foldable cover, which is fastened on the one hand to the operating element and on the other hand to the housing, the cover enclosing the movement space. It is important that the cover can join the movement of the operating element without being destroyed or to allow an intervention in the movement space. In this embodiment, the entire movement space is bounded or surrounded by a part of the housing, by the rear side of the operating element and by the cover. But it may well also be provided that the cover is designed as not fait- or bendable cover, for example in the form of a Bleckabdeckung. In this case, this Bleckabdeckung can be arranged on the back of the control element and "disappear" at a Einschwenkbewegung in a matching opening in the housing. This solution is also guaranteed that can not be used in the movement room.
    In contrast, a further mechanical variant can provide that the mechanical safety device is designed as a, preferably magnetic or spring-loaded, coupling which decouples the operating element from the adjusting device in the event of overload. Thus, the control element can not move further towards the housing as soon as an overload or jamming is present. Another equivalent possibility is a positive coupling or clamping solution.
    If the security device functions electronically, it is preferably provided that the electronic security device has at least one detection device which is signal-technically connected to the control or regulation unit. Preferably, this control unit is the same as the entire control unit for the forming machine. Of course, they can also be formed separately from each other.
    According to a specific variant of this electronic safety device can be provided that the at least one detection device is mounted on the housing or on the control element and forms a digital cover of the movement space in the form of a light barrier, wherein the interruption of the light barrier between the housing and control element, the movement of the adjusting device can be stopped , Thus, this electronic variant is based on the mechanical cover variant.
    According to a further electronic variant, it is preferably provided that the at least one detection device has a torque sensor and / or a force sensor which monitors a movement of the operating element and / or the adjusting device, wherein the movement of the adjusting device can be stopped in the event of overload. Particular care is taken to ensure that no excessive forces occur in the area of the movement of the operating element. The detection device can also be designed in the form of current monitoring. Especially in a pneumatic drive devices can act as a detection device and a pressure sensor.
    It is possible that the adjustment is adjusted purely by hand by pressing the control or by pulling the control. However, it is preferably provided that the adjusting device has a, preferably electromotive, drive device. Of course, other, for example pneumatic or hydraulic, drive variants can be provided.
    The operating element itself forms a man-machine interface between just the operator and the control unit. As essential components, the operating element may comprise a screen and / or a keyboard. For example, the screen can also be designed as a touchscreen, whereby the screen itself forms the keyboard.
    It is possible that the control element is mounted linearly or movably, for example, via a pivot point joint on the housing. For a simple movement possibility but is preferably provided that the operating element is pivotally mounted on the housing via a hinge with a rotation axis.
    Further details and advantages of the present invention will be explained in more detail with reference to the description of the figures with reference to the drawings illustrated below. Show in it;

    FIG. 1 shows a shaping machine 1, wherein essential parts of the shaping machine are surrounded by a housing 20. These essential, only schematically shown movement components 35 a
    Forming machine 1 are, for example, the closing unit, the injection unit and the handling device. These movement components 35 are controlled or regulated via a control unit 2. The control or regulating unit 2 is connected via signal lines 19 to the individual movement components 35 of the shaping machine 1. In order to allow an operator an easy influence on the control or regulation unit 2, a man-machine interface in the form of an operating device 3 is provided. This operating device 3 is arranged centrally on the housing 20. The operating device 3 is signal-wise connected via the signal line 18 with the control or regulating unit 2, which may also have a memory. The essential components of the operating device 3 are the housing 4, the operating element 5 and the adjusting device 6 for an adjusting movement of the operating element 5 relative to the housing 4. The operating element 5 itself has a screen 15 and / or a keyboard 16. FIG. 1 shows the invention with reference to a shaping machine 1. In the same way, the operating device 3 can also be used in a handling device, not shown.
    In Figure 2, the operating device 3 with swiveled control element 5 can be seen. In this case, the adjusting device 6 is in the form of a pneumatic or hydraulic piston-cylinder unit.
    In Figure 3, the control element 5 and the housing 4 can be seen in a schematic side view, wherein the operating element 5 is pivotally mounted on the housing 17 via the hinge 17. The pivoting area forms the movement space B for the operating element 5.
    In Figure 4, the control element 5 is completely pivoted back and lies flat on the housing 4. If now when closing the operator with his hand or other object enters the movement space B, there may be injury or damage.
    In order to solve this problem, a first variant of a safety device 7 is shown in FIG. According to Figure 5, the control element 5 is completely swung open, wherein the opening and closing movement is performed by the adjusting device 6. The adjusting device 6 comprises a drive device 14 which has a spindle 21 and a spindle nut 22, wherein the spindle nut 22 can be driven by an electric motor 23. By a rotational movement of the spindle nut 22, the spindle 21 is moved linearly. At the end of the spindle 21, this is connected to a connecting element 24, which in turn is rotatably articulated via a rotary joint 26 on the control element 5. On the connecting element 24 a plurality of regularly spaced latches 25 are formed on which a connected to the spindle 21 latch 28 is applied. This bar 28 in turn is acted upon by a spring 27. The latch 28 and a grid 25 together form a mechanical coupling 9 in order to transmit the movement of the spindle 21 to the connecting element 24 and thus further to the operating element 5. The latch 28 and the spring 27 together form the mechanical safety device 7.
    To explain the function of this safety device 7 in more detail, reference is made to FIGS. 6 and 7. In Figure 6 it can be seen that due to a movement of the electric motor 23, the spindle 21 has moved to the right. Since the latch 28 rests against the first grid 25, the control element 5 is pivoted in the closing direction. If now in this position, an operator with his hand 29 engages in the movement space B, the hand 29 is slightly clamped between the housing 4 and the control element 5.
    Now, if the drive device 14 continues to move and thus the spindle 21 is moved further to the right, the hand 29 would be further and further pinched. Due to the overload caused by the deadlock, however, the clutch 9 is released from a certain force reached. As soon as the clamping force is higher than the spring force of the spring 27, the bolt 28 can slide over the first grid 25 and latch on the next grid 25 again. If the power is getting too high there, of course, another decoupling can take place. In Figure 7 it can be seen how the adjusting device 6 is completely retracted, but the control element 5 is still in a slightly open, so not completely pivoted position is. If then the part or the hand 29 is removed between the housing and the operating element 5, the operating element 5 can be brought by pressing back into the complete closed position. As a result, the adjusting device 6 can then move normally in the opening direction again. This mechanical safety device 7 thus forms a good protection against damage and injuries.
    A similar mechanical safety device 7 is shown in FIG. In this case, a drive device 14 is again provided with a spindle 21, wherein the spindle 21 is connected to the control element 5 arranged on the pivot joint 26. This connection is made via the two magnets 30. These two magnets form a coupling 9. If now in the same manner as in Figure 6 or 7, a jamming by a hand 29 or an object in the movement space B occurs, then the magnets dissolve 30 of the clutch 9 from each other. Thus, this magnetic coupling 9 also forms a variant of the mechanical safety device 7.
    An electronic variant is shown in FIG. In this case, in turn, a drive device 14 with a spindle 21 and the connecting element 24 is provided. Furthermore, detection devices are arranged on the control element 5. A torque sensor 12 forms the detection device 10 arranged in or on the joint 17. The latter is connected to the control unit 2 via the signal line 33. In a similar manner, a force sensor 13 is arranged in the region of the connecting element 24 or in the region of the rotary joint 26. This force sensor 13 also forms a detection device 10, which is connected via the signal line 33 to the control unit 2. If now an overload is detected in a jamming of at least one of these detection devices 10, a control command 32 is transmitted to the electric motor 23 of the drive device 14 of the control unit 2, whereby the further adjustment movement of the adjusting device 6 is stopped. There is thus no mechanical decoupling but stopping or stopping the movement of the adjusting device 6.
    Another mechanical variant is shown in FIG. In this case, a bellows 34 is disposed between the control element 5 and the housing 4, which forms the mechanical safety device 7. This bellows 34 makes the movements of the operating element 5 with. Since no objects and no hand can get into the movement space B through this bellows 34, injuries and damage are certainly excluded.
    In contrast, FIG. 11 shows an electronic variant with, as it were, an electronic or digital "cover". In this case, components of a detection device 10 are arranged on the operating element 5 and on the housing 4. In particular, these are laser signals or light barriers 11 which are arranged in the region of the movement space B or around the movement space B. As soon as one of these light barriers 11 is interrupted, a corresponding signal is forwarded to the control or regulating unit 2, as in FIG. 9, so that the adjusting movement of the adjusting device 6 is then stopped via a control command 32.
    The present invention thus provides a novel safety option for operating devices 3 of shaping machines 1 or handling devices, which prevents damage to the operating device 3 and excludes injuries to operators.
