Description

[0001] The present invention relates to a system comprising a core drilling machine and an automatic feed device, wherein the core drilling machine is a Human Machine Interface (HMI) for controlling the core drilling machine and the automatic feed device. The system is characterized, among other things, by the fact that the menu navigation of the HMI can be automatically controlled depending on the operating states of the core drilling machine and / or the automatic feed device. In a further aspect, the invention relates to the use of an HMI for controlling a core drilling machine and / or an automatic feed device, wherein the core drilling machine and the automatic feed device together form a working system. Background of the invention:

[0002] In the field of machine tools, especially core drilling machines which may be equipped with diamond-tipped drill bits, for example, it is known to use the machine tools in conjunction with an automatic feed device. (auto feed ) to operate. Such devices, also known as automatic feed devices, are preferably designed to automatically drive the tool machine into the material to be machined, without the need for manually operated devices, such as rotary wheels, as was previously the case.

[0003] To achieve the desired work result, the automatic feed system and the machine tool must operate and be controlled in a coordinated manner. This requires inputs and / or settings to be made on the devices, which are usually entered using input devices. However, the input devices, especially on automatic feed systems, are often kept simple for cost reasons or to improve ease of use. In the prior art, systems consisting of a machine tool and an automatic feed system are known in which the automatic feed system does not include any display elements. Sometimes, such automatic feed systems only have an emergency stop button as a minimal solution for human-machine communication.In order to be able to control such a minimalist, automatic feed device as needed, it was proposed in the prior art to control the automatic feed device via the . Human Machine Interface (HMI) of the machine tool. In other words, it is known in the prior art that the HMI of the machine tool is used to control both the machine tool and the automatic feed device.

[0004] An HMI within the meaning of the invention can, for example, comprise a display, indicator elements, control elements, or other input and / or output means with which devices can be controlled by a person or with which information relating to the device can be displayed to the operator. In particular, the term HMI within the meaning of the invention describes those means on a device that enable or support communication between a person and a machine.

[0005] In conventional systems consisting of machine tools and automatic feeders, it is sometimes common practice for the automatic feeders to also be controlled via the machine tool's HMI. This leads to various difficulties and technical challenges. Although both the machine tool and the automatic feeder operate within the same system, it is desirable for the operating states of both system components to be displayed as simultaneously as possible. This is obviously difficult with only one display, or the display must be very small and therefore difficult for an operator to read. Furthermore, both the machine tool and the automatic feeder must be operated using the same controls—namely, the controls of the machine tool's HMI. This can easily lead to incorrect inputs, resulting in faulty and potentially damaging operation.This can lead to irreversible, undesirable work results. It turns out that both displaying and inputting data can be problematic if only one HMI – usually the machine tool's HMI – is used as the control medium for both the machine tool and the automatic feed device.

[0006] To remedy this situation, the prior art proposes that the operator of the system, consisting of the machine tool and the automatic feed device, select an operating mode and thus the device currently being operated. For the purposes of the invention, the term "operating mode" preferably means that at any given time ti, either the machine tool or the automatic feed device is controlled by the machine tool's HMI. Accordingly, there is a machine tool operating mode and an automatic feed device operating mode. The operator can thus select on the HMI whether they wish to operate and / or control the machine tool or the automatic feed device. They can also select the corresponding accessory elements relevant to the respective device, such as a digital spirit level or a manual drill step selection.However, this usually involves manual intervention in the system and often results in an undesirable loss of efficiency. Furthermore, such a selection process requires considerable expertise from the operator, which cannot always be guaranteed.

[0007] DE 10 2011 082 988 A1 discloses a control device for a machine tool, wherein the control device includes an operating panel which can be used, for example, to display a user interface.

[0008] EP 2 927 186 A2 relates to a method and system for operating a forklift truck in which a control unit displays, for example, a barcode with associated information depending on an operating state, which can be read with an additional, external device.

[0009] In DE 10 2016 010 068 a numerical control with menu is disclosed, wherein a machine learning model is used to determine a menu element display sequence in the menu display based on the state data.

[0010] The object of the present invention is to overcome the disadvantages of the prior art described above and to provide a system comprising a machine tool and an automatic feed device that facilitates both the display and input of data to and from the system. In particular, the known solution of controlling an automatic feed device via an HMI of the machine tool, with which the automatic feed device interacts, is to be improved in such a way that the operator is provided with the simplest, most self-explanatory, and most ergonomic operation possible of the different operating modes of the system.This is intended to provide, in particular, a particularly intuitive and easy-to-learn control system within the different operating modes of the system, whereby a function of the system should be enabled in the "normal" operation of the machine tool, as well as in conjunction with an automatic feed device.

[0011] The problem is solved by the subject matter of the independent claims. Advantageous embodiments relating to the subject matter of the independent claims are found in the dependent claims. Description of the invention:

[0012] According to the invention, a system is provided comprising a core drilling device and an automatic feed device, wherein the core drilling device is a Human Machine Interface(HMI) for controlling the core drilling machine and the automatic feed device. The system is characterized in that the HMI menu navigation is automatically controllable depending on the operating states of the core drilling machine and / or the automatic feed device, in that the HMI menu navigation comprises menu pages and the menu pages can be displayed depending on the operating states of the core drilling machine and / or the automatic feed device, so that the HMI menu navigation becomes automatically controllable depending on the operating states of the core drilling machine and / or the automatic feed device. In the context of the invention, this means that the individual menu pages or components of individual menu pages can be displayed depending on the operating states of the machine tool and / or the automatic feed device.

[0013] In the description of the invention, the core drilling machine is preferably also referred to as a machine tool; this always refers to the proposed core drilling machine. The automatic feed device is preferably configured to provide a cut assist function. In the context of the invention, this means that a tool of the machine tool is driven into a wall or substrate to be processed by means of the automatic feed device. The tool of the machine tool can, for example, be a core drill bit. Such core drill bits are often coated with diamonds or diamond chips to improve cutting performance. In these cases, it is preferred that the machine tool is a diamond core drilling machine. The invention consists in the fact that the menu navigation of the HMI of the core drilling machine is controlled depending on the operating states of the core drilling machine and / or the automatic feed device.This means that manual selection of the menu sub-items by the operator is no longer necessary.

[0014] The term "operating state of the machine tool" preferably describes, within the meaning of the invention, a state of the machine tool during operation of the proposed system. This state can be characterized by various settings and conditions of the machine tool. For example, the state of a machine tool can be characterized by the fact that the machine tool is switched on or that the machine tool is connected to an automatic feed device. Similarly, a state of the automatic feed device can be characterized by the fact that its emergency stop switch is released or that there is no connection to the machine tool. Preferably, a state is characterized by a set of different sub-states, wherein the set of sub-states preferably constitutes the operating state of a system component or of the proposed system.In accordance with the invention, it is particularly preferred that the operating states are formed by settings and / or sub-states of the machine tool and / or the automatic feed device.

[0015] The phrase "automatically controllable" in the context of the invention preferably means that different menu pages or menu overviews are displayed without manual intervention by a human operator. The automatic controllability of the menu navigation of the machine tool's HMI represents a significant advantage of the invention. The system is preferably able to recognize the respective operating state of the system components and / or the proposed system and, in light of the determined operating state, display those menu items or menu subpages that are relevant to the operator at the current operating time in order to ensure optimal operation of the system or its components. It is preferred in the context of the invention that the system is configured to recognize and evaluate the operating states of the machine tool and / or the automatic feed device.To determine the current operating states, the system or its components may have suitable sensors and / or a processor for evaluating and / or storing the collected and / or processed data.

[0016] Furthermore, the system can include communication means between the machine tool and the automatic feed device. The system can comprise a communication link that enables communication between the machine tool and the automatic feed device. It is preferred, according to the invention, that the system includes a communication link for communication between the machine tool and the automatic feed device. Preferably, the communication link of the proposed system is wireless, for example, as BluetoothThe communication link is designed, whereby other communication methods are also conceivable in the context of the present invention, for example NFC, radio, or other forms of communication particularly suitable for short distances. Communication can also be wired, for example, using a cable. It is preferred in the context of the invention that the communication link is configured to provide the data rates and / or transmission speed required for the control or communication between the machine tool and the automatic feed device.

[0017] The phrase "depending on the operating states of the machine tool and / or the automatic feed device" preferably means, within the meaning of the invention, that the system is configured to recognize the current operating state of the machine tool or the automatic feed device. The system operator is then only shown those sub-items or subpages of the menu navigation that are relevant to the respective operating state of the system via the machine tool's HMI. A subpage of the menu navigation may be relevant, for example, because information displayed on that subpage is necessary for the operator or for continuing work with the system.Relevance can also arise, for example, from the fact that a function is displayed on the HMI screen which can be selected in conjunction with operating or selection elements that also belong to the HMI of the machine tool, whereby this selection is necessary for continuing work with the system.

[0018] It is preferred, according to the invention, that the automatic feed device, in conjunction with the machine tool, is configured to execute, control, and / or effect a fully automatic drilling process. In particular, the fully automatic drilling process includes, but is not limited to, the operations of starting the drilling, drilling, detecting the completion of the borehole, and / or returning to the starting position. It is preferred, according to the invention, that the automatic feed device of the proposed system is controlled within the automatic feed device itself, with the machine tool preferably providing the necessary information. It is further preferred, according to the inventors, that the machine tool of the system provides a display and setting interface that can be used for controlling the automatic feed device.Preferably, these display and setting options are provided by the HMI on the machine tool. The HMI of the machine tool in the system proposed here is specifically designed to present complex information in a particularly clear manner. For this purpose, a matrix dot display can be used, for example. With such a display, which is specifically designed for displaying complex information, it is advantageous to be able to show not only alphanumeric lines, such as error codes, but also two-dimensional objects, such as diagrams, coordinate systems, or the like. The ability to display complex information distinguishes the present invention in particular from so-called segment displays, which are mostly limited to displaying single-line combinations of letters and numbers, similar to a non-programmable calculator.

[0019] The invention will be illustrated below by application examples. For example, if the automatic feed device and the machine tool are connected, data exchange between the two system components is possible, an emergency stop button on the automatic feed device is enabled, and an on / off switch on the machine tool is deactivated, the display and control elements of the machine tool's HMI can be activated to position the automatic feed device and / or align the machine tool's drilling system. This operating state of the system is referred to, for example, as "in the context of the invention." Cut Assist Positioning ModeThe positioning of the automatic feed device specifically concerns its up and down movement. The alignment of the drilling system can preferably be carried out with the aid of a digital spirit level, which can be part of the system, particularly the machine tool. If, in this Cut Assist Positioning Mode When the on / off switch of the machine tool is activated, the display and control elements of the machine tool's HMI switch to the so-called Cut Assist Setting mode. By Cut Assist Setting ModeThe display and control elements can be activated for setting and starting the automatic drilling operation. Setting the automatic drilling operation can include, for example, switching the breakthrough detection on and off or a power reduction function for the automatic feed device. It is preferred, according to the invention, that the display and control elements switch to "normal" core drilling operation when the automatic drilling operation is started.

[0020] It is preferred within the scope of the invention that components of the machine tool's HMI are selected from a group that may include, but are not limited to, the following components: display, touchscreen, controls, buttons, switches, output devices, and / or indicators. In particular, the system or the HMI may also include a dashboard or dashboard function. For example, the HMI may be configured to display various functions on the screen. These functions may include, for example, a gear indicator, error and / or warning messages, and information on the status of the communication connection. (Bluetooth) (on or off) without being limited to this. In particular, the HMI of the machine tool of the present invention can display several different pieces of information simultaneously, since the display is advantageously not limited to a single-line display.
