Description

System for machining workpieces

Technical area

The invention relates to a system for processing

Workpieces, which are preferably at least partially made of wood, wood materials, plastic or the like, with a processing device for performing the

Workpiece machining, which has a control device with a data transmission interface.

State of the art

Come in the field of furniture and component industry

Various types of processing equipment used to different machining operations on workpieces

perform. Examples of such machining operations are machining operations such as formatting, sawing, milling, drilling or the like, but also

Coating operations such as the gluing of edges or cover materials.

Such machines usually have one

Machine control, by means of which the operation of the processing device based on

Processing data is controlled. The machine control is usually operated and monitored by an operator. Here are significant non-productive times, since the

Operator must be present for the operation or monitoring of the machine on the machine control and can perform no or only minor other activities. Furthermore, it is known in machine tools, machine information such as status or

Pass error messages via a remote data transmission interface to a terminal, for example, for remote maintenance purposes.

Presentation of the invention

It is an object of the invention, a system and a method for machining workpieces with improved

Provide operating efficiency.

This object is achieved by a system for

Machining of workpieces according to claim 1 and a

Method for machining workpieces according to claim 10. Particularly preferred developments of the invention are specified in the dependent claims.

The invention is based on the idea of operating a processing machine spatially from the actual

Decoupling processing device. For this purpose, the invention provides that in a system for

Machining of workpieces, the control device

is set up, state information of the

Processing device over the

Data transfer interface to the terminal to pass.

In this way, the activity of an operator

spatially and thus temporally by the operation of the

Machining device be decoupled. As a result, the operating efficiency can be significantly increased because the Nebenbzw. Dead times that an operator so far at a

Machining device had to spend drastically

can be reduced. For example, an operator need not be present at the processing device for monitoring the processing device, but can move away completely free of the processing device and perform other value-adding activities. At the same time, however, the operator can also exercise their monitoring activities, since

Condition information of the processing device are always available at the terminal, for example in the form of a mere display or an active notification or

Alerting.

According to one embodiment of the invention, it is provided that the system has a plurality of terminals and / or several

Processing devices, each having a

Have a data transmission interface. This results in a particularly pronounced increase in

Production efficiency. Depending on the design of the system, for example, an operator can be put in the position to monitor several processing devices at the same time and possibly also to operate. In this case, the system can also, for example, a processing order or

Generate prioritization and on the at least one

Display terminal, which leads to further efficiency improvements. Furthermore, it is also possible with this concept to integrate several terminals or operators, so that depending on the orientation of the system, either a particularly short reaction time of an operator to status information of the system is achieved, or a particularly effective

Reduction of side and dead times of the respective

Operators can be realized.

Overall, on this basis can also be a networked

Complete system with multiple processing devices and

Terminals or operators are realized, in which a flexible and highly efficient, dynamic allocation of processing devices and operators can be achieved with maximum efficiency. In principle, the at least one terminal can be a stationary terminal that is placed at a suitable location, for example, at a location where an operator can perform efficiency-enhancing activities. Alternatively, it is provided according to a development of the invention that at least one terminal is mobile. This gives the respective operator maximum flexibility for the exercise of their activity, so that the

Operator needs-based different,

perform efficiency-enhancing activities. This is especially true when networking several

Processing devices of advantage, in which case also one or more processing devices

may have stationary terminal, which

State information about one or more others

Indicates processing devices.

In mobile terminals, it is particularly preferred that the at least one terminal has means for carrying the terminal on the body of an operator, in particular on the arm or in the head area. This results in an effortless

Readability and operability of the at least one terminal for the operator, and the operator is not hindered in their activity, so to speak, has "hands free".

According to one development of the invention, it is provided that at least one terminal has information output means which are selected from image output means, sound output means and tactile output means, in particular vibration output means. Depending on the application, the nature of the

Information output means have certain advantages. Complex facts can best be solved with one

Display image output device. Sound output devices are often suitable for simpler information, but have the advantage that the operator's attention can be more effectively aroused and the operator, for example, with the eyes and Hands can continue to pursue their current activity. Similar considerations apply to

Tastausgabemittel, in particular in the case of

Vibration output means.

The information output means may include one or more of said output means and be distributed to one or more components. A particularly versatile and highly detailed and well-perceptible information output results when according to a development of the invention, the image output of at least one terminal includes a virtual or projected representation. An example of such an image output may be in a terminal worn on the head of a user in the area of the eyes, such as a so-called "smart glasses".

In addition, according to a development of the invention, it is provided that the control device is set up, via the data transmission interface, instructions to the terminal for output to an operator

pass. This results in a considerable increase in the field of application of the system according to the invention, which also results in a significant increase in operating efficiency

accompanied. For example, the operator can not only be notified about error messages or status information, but can also immediately receive solution proposals by means of the system according to the invention in order to eliminate the respective problem. Likewise, the operator can be informed by means of the system according to the invention, which

Operating steps for the proper progress of the

Machining operations are required, for example

Load new workpieces, replace

Consumables, replacing tools or

like. The instructions can be used by means of the aforementioned information output means

be passed on to the operator in a variety of ways, for example in the form of GPS data, Camera images, virtual representations, projections and various other forms of presentation.

According to a development of the invention is further

provided that at least one terminal

Having information input means. This provides an interactive system in which the

Operator is not only a recipient of information, but also interactive information or instructions or commands can return to the system according to the invention. The information input means may be

for example, to key input means act, in particular a keyboard or a touch screen. Alternatively or

however, in addition, sound input means may also be used, such as speech recognition means.

Further alternatively or additionally also

Motion detection means are used. typical

Motion detection means are gesture detection means, in which the operator can enter information into the at least one terminal by a mere movement of a body part. Another type of one

Motion detection means is a so-called virtual touch screen, in which a virtual image is generated or projected in the field of view of the operator and a

Movement of the user is related to the virtual or projected image in order to effect an information input.

In principle, any information from at least one terminal can be transmitted to at least one control device by means of the information input means. According to one embodiment of the invention, however

provided that at least one control device is set up to receive, via the data transmission interface, control commands for the respective processing device that are connected to at least one terminal of one Operator were entered. This results in a further increase in operating efficiency, since the

Operator not necessarily to the respective

Machining device must go to the

Control processing device.

To achieve a reliable and trouble-free

Communication, at least one terminal advantageously have a wireless data transmission interface, for example, on WLAN, Bluetooth or various

Mobile standards is based.

The advantages mentioned above can be particularly effective with the inventive method according to

To achieve claim 10.

Fig. 2 shows schematically a further embodiment of the system according to the invention.

Detailed description of preferred embodiments

Hereinafter, preferred embodiments of the invention will be explained in detail with reference to the accompanying drawings. Other modifications of certain individual features mentioned in this connection can each be combined with one another in order to form new embodiments.

A system 1 for machining workpieces according to an embodiment of the invention is shown schematically in FIG. The system 1 is used to process a Workpiece, which at least partially made of wood,

Wood materials, plastic or the like, for example. A solid wood panel, a plywood panel, a

Chipboard, MDF board, HDF board or similar Such workpieces are preferred in the field of furniture and

Component industry used. Purely by way of example, it can be a kitchen worktop, a shelf, a

Floor panel, door, or similar act.

In the present embodiment, the system 1 comprises, by way of example only, three processing devices B 1, B 2 and B 3, each of which serves to carry out a workpiece processing. Each of the processing devices has a control device not shown with a

Data transmission interface.

Further, in the present embodiment, the system includes a terminal 10, although a plurality of terminals 10

can be provided. The terminal 10 has a data transmission interface (not shown) serving and arranged with the respective ones

Communication interfaces of the processing devices Bl, B2 and B3 to communicate. The connection takes place via a data connection 15, which in the present

Embodiment is designed as a wireless data connection. The data connection 15 can be designed in the manner of a so-called "cloud" and, if appropriate, also have its own server 20 for this purpose. The wireless

Data connection itself can be based on various technologies, such as wireless, Bluetooth or a

Mobile connection.

The control devices of the respective

Machining devices Bl, B2 and B3 are to

set up via the associated

Data transmission interface state information of the respective processing device to the terminal 10th pass. The state information may be a wide variety of information, such as the processing status of a workpiece (in particular, the processing time remaining), the operating state or maintenance status of the respective processing device,

Error messages, or a variety of others

State information.

The terminal 10 is in the present

Embodiment to a mobile terminal, which is designed to be worn on the body of an operator. A preferred embodiment of such a terminal 10 is illustrated in Fig. 2, which also shows an embodiment of the system according to the invention. In this case, the terminal 10 is configured in this embodiment as so-called smart glasses, which is supported by brackets 12 at the head of an operator. The terminal 10 has both a

Picture output as well as a sound output to pass information to the operator. In addition, that could

Terminal 10 also have vibration output means.

The image edition includes in the present

Embodiment also the output of a virtual image 10a, which is shown schematically in Fig. 2. This can be a projected representation that

for example, actually to a subsoil or

if necessary, also a body part of the user is projected. On the other hand, the projected representation can also take place in the smart goggles themselves, but appear to float freely in space for the user.

The presentation of smart glasses can also be done in the manner of a virtual reality or augmented reality. In the latter, a superimposed representation of

Reality and virtual representation in such a way that they complement each other to form an overall picture. Thanks to these information output means, the terminal 10 is capable of other information besides state information

Information such as in particular to indicate instructions for the respective operator. In such

Handling instructions can be, for example, an operator guidance of the operator on the machine for

act various handling and Rüsttätigkeiten. For this purpose, a wide variety of presentation forms including camera images, GPS data, virtual representations, projections or the like can be displayed on the terminal 10.

In addition to the aforementioned information output means, the terminal 10 in the present embodiment

various information input means such as

For example, a microphone that can possibly also provide speech recognition, as well as a physical or virtual

Keyboard or touch screen. A virtual touch screen can be based on a gesture detection by the

For example, a user moves a hand into certain areas of the virtual display 10a and this movement is used to input information.

In this way, the operator is allowed to not only state information of the respective

Processing device can be provided, but that the operator can also return control commands to the respective processing device. For this purpose, the control devices of the respective

Machining devices Bl, B2, B3 set up to receive control commands via the data transmission interface, which were input to at least one terminal 10 by an operator.

The operation of the system 1 according to the invention takes place, for example, as follows. First, an operator, as shown in Fig. 2, takes on a processing machine (Bl, for example) before a machine operation and thereby follows instructions that are displayed to the operator by means of the terminal 10 via the virtual display 10a. For example, the operator inserts a specific tool W into the processing device Bl. To

At the conclusion of this process, the operator confirms this by virtual input in the virtual representation 10a. Subsequently, the processing device Bl performs a

Processing operation in which an intervention of

Operator is not required for a certain period of time.

The operator can now the

Machining devices B2 or B3 or others

Turn to activities. For this purpose, the operator is informed by means of the terminal 10 of the status information of the respective processing devices Bl, B2 and B3, so that the operator can decide whether intervention or action is currently required on the processing devices.

If no interventions or actions are currently required on the processing devices B1, B2 or B3, the operator can carry out further value-adding activities. However, as soon as measures must be taken at a processing device Bl, B2, B3, they are displayed to the operator by means of the terminal, or the

Operator can at regular intervals the

verify proper operation of the processing devices by means of a status indicator in the terminal.

If necessary, the operator can display various status views for this purpose. All in all, one can speak thus to a certain extent of a "Produktionsnavi", in which the operator (or possibly several

Operators) by means of (at least one) terminal 10 always a complete overview of the state of individual processing devices and thus also the

Overall system possesses.

Once a processing device an intervention of

Operator requires, this is displayed to the operator in the terminal 10. This may be, for example, the mere inputting of a control command to a

Handling device act without the

Operator must go to the appropriate processing device. For example, the control device of the respective processing device may request the release for a particular machine operation or the next workpiece charge from the operator. Alternatively or additionally, it is also possible that the operator by means of the terminal 10, a specific instruction is displayed, for example, to a specific

Returning processing device and there

For example, insert new workpieces, exchange tools, make repairs, etc.

Instead of the smart glasses described above, a wide variety of mobile or stationary terminals can be used in the context of the present invention. The spectrum ranges from simple headsets (possibly with microphone and voice control) to highly complex smart devices that cover the entire range of input and output devices.

In addition, the terminal 10 may also include at least one sensor relating to the characteristics of the operator. By means of this at least one sensor different safety and comfort functions can be performed, for example, a fatigue detection of

Operator, but also a mere identification of the

Operator to various operator-specific

(Comfort) settings of the respective Make processing device based on the recognized operator.
