    «♦ 71626 22 / sk 1
    The invention relates to an operating unit for an injection molding machine, with an operating element for triggering at least one movement of a drive unit of the injection molding machine, wherein the operating element is movable from a basic position into a triggering region triggering the movement of the drive unit. In addition, the invention relates to an injection molding machine with at least one drive unit for moving a part of the injection molding machine and such a control unit.
    In the operation of injection molding machines, there are already numerous different variants to increase the ease of use. In recent years, more and more control units have prevailed, which have a smaller number of controls. This is not least due to the fact that operating units with touch-sensitive screens are being used more and more often instead of purely mechanical switches. Also, a variety of display options on the same switch several functions can be assigned. An example of such a control unit is given in AT 009 943 U1. In this case, the control element provided with the reference numeral 7 is movable in two directions in triggering areas, whereby a corresponding movement of a part of the injection molding machine is triggered.
    As soon as the operator has turned on this operating element, the movement is immediately executed according to a stored speed profile. The disadvantage here is that the operator has only cumbersome influence on the actual speed of the triggered movement of a drive unit. For example, prior to performing the movement on the screen, the operator could set a different speed or speed profile. He must thus carry out a reprogramming to be done in a separate previous step or specify changes in the speed before actuation.
    The object of the present invention is to provide a comparison with the prior art improved control unit. In particular, the ease of use is to be increased and a simpler and faster influence 2 by the operator on the speed of the triggered by the operating movement of the control element movement of a drive unit be possible.
    This is achieved for a control unit with the features of claim 1. Preferred embodiments are specified in the subclaims.
    According to the invention, it is accordingly provided that the triggering area has a multiplicity of intermediate positions between the basic position and a maximum position, the speed of the triggered movement of the drive unit being dependent on the distance of the selected intermediate position of the operating element from the basic position. Thus, the operator can influence the speed without prior change of a speed profile by the actuated by him intermediate division or maximum position of the control element. Accordingly, it is preferably provided that the greater the distance of the intermediate position from the basic position, the higher the speed of the triggered movement of the drive unit.
    At least two, preferably regularly spaced, intermediate positions should be provided between the basic position and the maximum position. It is also possible, for example, to have five or eight concrete, regularly spaced steps. Preferably, however, it is provided that the intermediate divisions in the triggering area are stepless. Preferably, the control is self-resetting, i. when released, the element returns automatically to the normal position and the triggered movement of a drive unit is stopped. In this case, any machine or robot movement movement (axis movement) or a sequence of movements is assigned or assignable to the operating element (for example, mold closing and opening movement).
    Furthermore, a preferred operating unit has a screen for displaying machine-specific parameters, wherein it is further preferably provided that the machine-specific parameters can also be set by the operating element. * ♦ • »3
    In order to convert an operating movement performed on the control element into a signal for controlling or regulating the movement of the drive unit, a control or regulating unit arranged logically between operating element and drive unit is preferably provided.
    A particular advantage of the present invention is that movements of a plurality of drive units, preferably one after the other, can be triggered by the operating element. As a result, the operating element forms a handy and clear single-button operation for an operating unit of an injection molding machine. In order to avoid overlaps or incorrect operation, it is preferably provided that only one movement of one of the drive units can be triggered by the operating element at a time.
    Furthermore, it is preferably provided that at least one speed profile for the movement of a drive unit is stored in the control or regulation unit, wherein the speed profile corresponds to the movement of the drive unit at maximum position of the operating element. For an individual influencing the speed, which can be easily estimated or read by the operator, it is preferably provided that, depending on the intermediate position of the operating element between basic position and maximum position, the triggered movement of the drive unit has a speed profile of the speed profile corresponding to the intermediate position. Thus, the position of the operating element determines the travel speed of the drive unit or axle. The greater the distance to the basic position, the faster the triggered movement.
    According to a first variant of the present invention can be provided that the operating element is designed as a, preferably rotatable, mechanical knob or switch. In order to guarantee the most ergonomic possible design, the operating element can be used as handwheel, lever, slider, joystick or similar. be educated. An alternative to this mechanical design of the operating element may provide that the operating element is displayed on a touch-sensitive screen. That the control element is shown purely as a programmable and movable button on the screen of the control unit. According to a further alternative or as a hybrid form it can be provided that the operating element is designed as a separate from the main screen touchpad.
    The control element may additionally be formed with one or more pushbuttons or with one or more electrical switch contacts. This allows the following functions to be realized: - Change of function:
    By pressing the control element, a change of the driven by the control element drive unit takes place. For example, the stored function of "Close mold / Open mold" changes to the function "Nozzle forward / backward". Through intelligent sequence of movements (movements) can be traversed by means of this control element, the entire production cycle in manual mode very quickly and easily. Thus, it is preferably provided that the change is dependent on settable or deposited in the control unit or control sequences. - Automatic mode:
    In automatic mode, the control element has a start button function. That is, when the machine has been set to automatic mode by hand, the operating element becomes the start button, which saves space compared with previous operating units - program interruption:
    The control element can also be used to switch to an automatic mode after a successful cycle start. The current cycle is interrupted by pressing the control element.
    A further preferred embodiment of the present invention may provide that the operating element is movable from the basic position in two directions in each case in Ausiösebereiche, wherein the selected direction of the
    Triggering in relation to the basic position, the direction of movement of the triggered movement of the drive unit is dependent. For example, a movement of the control element to the right, the mold closing, while a movement to the left initiates the mold opening movement. It can be present at a rotatable control while a limit stop (maximum position) at +/- 75 degrees from the basic position.
    Protection is also desired for an injection molding machine with at least one drive unit for moving a part of the injection molding machine and a control unit according to the invention. As a drive unit can, for example, a toggle mechanism, a core pull, an ejector, a metering device, a turntable u.v.m. be considered. The control unit according to the invention can not only for an injection molding machine itself, but also for a handling robot, a temperature control, a conveyor belt or the like, which are part of an injection molding, are used, by the control unit, for example, the movement of a robot axis (corresponding to the drive unit) au solvable is.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:
    1 shows schematically an injection molding machine together with control unit,
    2 a rotatable operating element,
    3 shows a displaceable operating element with triggering regions, and FIG. 4 shows a diagram of a velocity profile.
    In Figure 1, an injection molding machine 2 is shown in the left area. In this case, the movable platen 9 is slidably mounted on the frame 14. This mold clamping plate 9 is movable by a (schematically indicated toggle mechanism 15 ~ which forms a drive unit 4), whereby the mold halves of the tool 11 can be pressed together between the movable mold mounting plate 9 and the fixed mold mounting plate 10 6. The cavity formed in the tool 11 is over the For example, carbon granules can be introduced into the injection unit 12 via a hopper 13 and are melted therein by a screw (forms a further drive unit 4) and subsequently injected.
    The movements of the individual drive units 4 of the injection molding machine 2 are controlled or regulated via the operating unit 1. The operating unit 1 has a preferably touch-sensitive screen 5, on which, inter alia, machine-specific parameters P can be displayed. Below the screen 5, a plurality of additional switches 8, mainly with safety functions, arranged. As the most important component for the normal operating mode or for production, the operating element 3 is provided on the operating unit 1. According to this Figure 1, the control element 3 is shown in its normal position G, in which still no movement of a drive unit 4 of the injection molding machine 2 is triggered. By moving the operating element 3 to the left or right, a movement of a drive unit 4 of the injection molding machine 2 is triggered. In this case, a signal is forwarded to the control or regulating unit 7, which forwards a signal depending on the currently running sequence Q or of the speed profile F stored for the drive unit 4 and triggers a movement of a drive unit 4. By pressing on the control element 3 or by selection via an image page, the desired movement or functionality (next step of the sequence sequence Q) can be selected and assigned to the control element 3. On the screen 5 or on a separate display field, this selection is shown.
    Such a change of the function preferably always takes place in the same sequence in accordance with an adjustable or selectable sequence of sequences Q. First, for example, the operating element 3 is moved in the direction of the "closing sequence". As a result, a movement is carried out according to the set sequence. Stepping mode by additionally pressing an enabling key is possible. This is followed by pressing the operating element 3. This changes the function from "closing sequence / opening sequence" to the function "nozzle forward / backward".
    Subsequently, the operating element is actuated in the direction of "nozzle before". This will execute this movement. When pressed again on the control element 3, there is a change from the function "nozzle forward / backward" to the function "injection / dosing". Upon actuation of the control element 3 in the direction of "injection" the injection is performed. Subsequently, the operating element is moved in the direction of "dosing", whereby the dosing in the injection unit 12 is triggered. When pressing the operating element 3, the function of "injection / dosing" changes to the function "closing sequence / opening sequence". When moving the operating element in the direction of "opening sequence", the movable mold clamping plate 9 is moved in the opening direction. Next, the operation of an ejector o.ä. respectively.
    FIG. 2 shows a perspective view of a mechanical operating element 2 which can be actuated by the hand of an operator.
    FIG. 3 shows a linearly displaceable operating element 3. The operating element 3 is thereby in the basic position G. Upon movement of the operating element 3 from the basic position G in one of the two trigger areas A, the operating element 3 first enters an intermediate position Z (see right, dashed control element 3). The control element 3 is movable up to a maximum position M (see left, dashed line control 3). Analogously, these triggering regions A or positions G, Z and M apply to a rotatable operating element 3. FIG. 4 shows a diagram of how it can be stored in a control unit 7. In this case, the speed profile F for the movement of a drive unit 4 of an injection molding machine 2 is shown. On the vertical axis, the travel speed of the drive unit 4 is given in mm / sec. The times t are indicated in seconds steps on the horizontal axis. When the operating element 3 is in its maximum position M, the speed of the drive unit 4 is traversed according to the speed profile F (100%). When the control element 3 is halfway between the 8
    Home position G and the maximum position M, the movement of the drive unit 4 at half speed according to the speed profile F (50%) is performed. The same applies to the velocity profile F (30%) and all other possible intermediate positions Z.
    By the present invention, two major advantages over the previously known operating philosophies are thus given. Thus, on the one hand, the traversing speed of the actuated drive unit 4 is dependent on the position or position of the operating element 3. The setting for the nominal speeds of the production cycle need not be changed when should be moved slower in manual mode / must. Rather, the set target speed in manual mode, the maximum speed that can be driven with the control element 3. On the other hand, the machine can be operated in manual mode via a single button. The hand always remains on the control element 3, wherein the selection of the desired movement or movement group is performed by pressing the control element 3. There is thus no search of the desired key required. Of course, all other types of movement other than pushing (e.g., pulling, panning, etc.) may be used for the function change. It is only important that with the control element two different types of operating movements are possible. On the one hand, a movement option must be clearly assigned to the cruise control. The other possibility of movement must clearly allow a conclusion to a change of function.
