TOUCH SCREEN PANEL FOR MULTI AXES MOVEMENTS OF INJECTION PRESSES FOR PLASTIC MATERIAL

Abstract

Touch screen operator control panel for industrial machines, in particular for the control of manoeuvring of the axes of injection presses for plastics, including an operator interface on which icons are displayed indicating the various axes of a press, the icons being individually selectable in order to be dragged into an area of manoeuvring where they are translatable in the two ways of a prefixed direction to impart the corresponding movements to the selected axis, wherein the possibility is provided of simultaneously displaying in the manoeuvring area icons of several press axes correlated one to the other and of actuating sequentially/selectively the movements of these press axes by dragging a central zone of the manoeuvring area in the corresponding different directions wherein the respective icons of the press axes are displayed.

Description

[0015] Further features of the invention will be made clearer by the following detailed description, referred to one of its embodiments purely by way of a non-limiting example, illustrated in the accompanying drawings, in which:

[0016] FIG. 1 is a schematic view of a part of the operator interface of a touch screen panel for the control of an injection press for plastic materials, showing an example of manoeuvring on the mould axis alone, according to the prior art;

[0017] FIG. 2 is a schematic view like that of FIG. 1 showing the simultaneous display of two orthogonal axes movements on the touch screen interface according to the invention;

[0018] FIG. 3 is a view of the operator interface of a touch screen panel according to the invention, with the mould icon selected for the subsequent movements highlighted with a circle;

[0019] FIG. 4 shows the interface of FIG. 3 with the mould icon dragged to the centre of the area of manoeuvring shown in FIG. 2;

[0020] FIGS. 5 and 6 show respectively two examples of manoeuvring of the extractor axis and of the mould axis;

[0021] FIG. 7 is a view of the touch screen interface like that of FIG. 3, with the plasticisation screw highlighted;

[0022] FIG. 8 is a view of the interface showing the icon of the screw brought to the centre of the manoeuvring area;

[0023] FIG. 9 is a view of the interface of the touch screen panel of the invention schematising the speed of movement proportional to the distance of displacement of the corresponding icon.

[0024] Referring to FIG. 2, the solution proposed by the invention, with respect to existing ones, allows the simultaneous display of more than one axis movement (two in this case) in the press control and the manoeuvring on several axes accessible by the touch screen interface of the injection press.

[0025] Through this solution the press operator will have a direct view of several axis movements which can be performed and will be able to perform the manoeuvring by dragging the finger positioned on a central circle 1 of the manoeuvring area 2 determined for example by the intersection of two ellipses, in the direction of the movement to be performed, with consequent simplification in the use of the machine.

[0026] Starting from the central circle 1, the axis to be moved will be able to be chosen, dragging the finger in the horizontal or vertical direction. The movement of the axis will be performed by the displacement in the direction chosen.

[0027] During execution of the movement the icon of the movement underway will be displayed in the circle 1.

[0028] The method of manoeuvring is not tied to just the two horizontal and vertical axes but can be actuated at a number of axes higher than 2, in which case displacements can for example be provided at 45 with respect to those illustrated in FIG. 2.

[0029] FIG. 3 shows schematically a series of icons 3 indicating the axis to be moved which can be selected through the dragging in the appropriate area 2 (use movement) for actuating the movement. This mechanism allows a direct and fast choice of the movement.

[0030] Since the mould axis is normally correlated to the extractor, following the dragging of the mould axis, in the central circle 1 of the manoeuvring area 2, the mould and extractor axes will be displayed (FIG. 4).

[0031] Starting therefore from the central circle 1, the axis to be moved can be chosen. Dragging the finger in the horizontal or vertical direction, the movement of the axis will be performed with consequent manoeuvring. During execution of the movement the icon of the movement underway will be displayed in the circle 1.

[0032] The accompanying FIG. 5 shows an example of manoeuvring of the extractor axis in the vertical direction, while FIG. 6 shows an example of manoeuvring of the mould axis in the horizontal direction.

[0033] FIG. 7 shows the operator interface of the touch screen panel with the screw axis highlighted with a circle, and FIG. 8 shows this icon dragged into the central circle 1 of the area of manoeuvring 2, where the axes of injection and screw rotation will be displayed, which are normally correlated one to the other.

[0034] In the example shown in FIG. 8 the dragging with the finger of the circle 1 in the horizontal direction corresponds to a manoeuvring of the injection axis, while a dragging in the vertical direction corresponds to a rotation of the screw.

[0035] Attribution of associations: horizontal axis with one movement and vertical axis with a second movement will be defined dynamically by the software application of the machine, favouring for the horizontal axes the main movements of the injection press such as the movement of the mould and of the plasticisation screw.

[0036] Finally, actuation is provided of the regulation of the speed of each movement on the basis of the position achieved with reference to the centre of the manoeuvring area 2. In practice, the extent of the displacement of the circle 1 corresponds to the speed of actuation of the relevant manoeuvring. This allows, in addition to the direction and sequence of the movement, also the regulation of the speed of movement proportionally to the distance covered with the finger from the centre of the manoeuvring area 2 of the touch screen panel.

[0037] FIG. 9 shows schematically the displacement of the mould icon corresponding to a certain speed of manoeuvring of the mould axis.

[0038] The writing in FIGS. 4, 8 and 9 indicates by way of an example the positions of the members involved.

[0039] From what is disclosed the advantages appear clear of the touch screen panel with integrated multi-axis manoeuvring of an injection press for plastic materials according to the invention, which makes the task of the operator in the control of the machine considerably easier.

[0040] Naturally the invention is not limited to the particular embodiment described previously and illustrated in the accompanying drawings, but numerous detail changes may be made thereto, within the reach of the person skilled in the art, without thereby departing from the scope of the same invention, as defined by the appended claims.
