DESCRIPTION

Chamfering machine

The invention relates to a chamfering machine for machining a edge of a workpiece in the form of a plate that moves continuously in a transport direction, with a transport device, which extends from a machine inlet area towards a zone of machine output for transporting the workpiece, and with at least one machining unit to machine the workpiece edge.

By means of a chamfering machine of this type, a edge of a workpiece can be specifically machined a narrow side of the workpiece oriented parallel to the direction of transport of the workpiece. For example, it may be provided that the song is covered with a band or strip material. The singing material of this type is often referred to as ..tapacantos ", which is fed to the edge oriented parallel to the direction of transport (narrow side) of the workpiece and is fixed to the edge. The chamfering machine may present for this purpose. a machining unit in the form of a edge cladding unit. In many cases the workpiece that moves continuously is then fed together with the edge material fixed to the edge for subsequent machining, in which the protruding parts of the edge material that protrude from the narrow side of the workpiece is separated or the edge material is profiled. The chamfering machine can, for example, have saw and / or milling units. polished.

Preferably, by means of the chamfering machine, the edge of a workpiece made of wood or wood substitutes is machined, in particular a chipboard. For transporting the workpiece, the chamfering machine has a transport device, for example a transport chain, which extends from a machine inlet zone to a machine outlet zone. In the machine entry area the workpiece to be machined can be placed by a user on the transport device. The machine input zone can therefore also be referred to as a feed zone. In the machine exit zone the mechanized work piece can be removed from the transport device. Often several work pieces can be placed consecutively in the machine entry area on the transport device, so that a first piece of work is already machined

work, when the user deposits a second piece of work on the transport device.

In many cases, the chamfering machine features a monitor, in which the user is shown status information of the edge gluing machine. The user can include in the monitor for example the information of whether a correct machine operation or a defective condition is present, for example a defect of a machining unit, and / or if the machine is in a machining mode with active machining units or in a reserve mode with inactive machining units. In many cases the user can detect on the monitor if a workpiece is between the machine inlet zone and the machine outlet zone on the transport device. The user must pay attention that only one work piece is placed in the machine inlet area on the transport device, when a correct operation occurs and not for example a faulty state. However, the user can frequently detect the monitor during the placement of a workpiece in the machine entrance area only with difficulty, since in this sense he must direct his view away from the transport device and orient it towards the monitor. This makes it difficult to operate the machine.

Therefore, the objective of the present invention is to perfect a chamfering machine of the type mentioned at the beginning in such a way that it has a simpler handling.

This objective is achieved in accordance with the invention in the case of a generic type chamfering machine because the chamfering machine has a signaling device, which signals a state of the chamfering machine to the user in the transport device in the machine entry zone.

The idea comes to the invention that the user is facilitated with the handling of the chamfering machine, by signaling the current state of the chamfering machine directly in the machine entrance area on the transport device. When placing a workpiece in the machine entrance area on the transport device, the user can detect the condition of the chamfering machine directly, without taking his view of the transport device apart. In particular, for him it is not necessary, during the placement of a workpiece on the transport device, to direct its view to a monitor arranged towards the transport device, in order to obtain the current status information.

The signaling device transmits to the user during the placement of a work piece on the transport device a status information on the current state of the chamfering machine. A defective state of the machine can therefore be indicated to the user in the place where the attention of the user is directed in the placement of the work piece, specifically in the transport device in the machine entry area. Since the user does not have to look away from the transport device, the danger of the workpiece being wrongly placed on the transport device is low. Preferably the signaling device is oriented to generate an optical signal, that is to say it configures an optical signaling device, for example the signaling device may have an optical signaling device or a signal source for an optical signal. In the case of an advantageous configuration of the invention, the signaling device has a light source, which illuminates at least one sector of the transport device in the machine entrance area depending on the conditioner of the chamfering machine. By means of the lighting depending on the state of at least one sector of the transport device, the user can visually detect the conditioner of the chamfering machine. The lighting varies in the case of a state modification, so that for example in the case of a defective condition of the chamfering machine, another illumination is presented other than in the case of a correct state of the chamfering machine.

The advantage is that when the light source of the signaling device illuminates at least one sector of the transport device in the machine entrance area diagonally or perpendicularly from above. This has the advantage that the user can detect the current state of the machine also on the upper side of a workpiece arranged in the machine inlet area on the transport device. While the workpiece is not yet deposited on the transport device, the user detects the state of the machine by lighting the transport device. If the user has deposited a workpiece on the transport device, then the upper side of the workpiece illuminates at least partially depending on the state.

The sector of the transport device illuminated by the signaling device may extend in the direction of transport of the workpiece for example by a length of at least 10 cm, in particular by a length of at least 30 cm. Transversally to the direction of transport of the work piece the sector

The illumination of the transport device may extend for example by a width of at least 10 cm, in particular by a width of at least 30 cm. Also with complicated viewing relationships, the current state of the machine can be signaled to the user so that it can be properly detected by lighting depending on the state of the sector. It is especially advantageous, when the light color of the light source can be modified depending on the state of the chamfering machine. in the case of such a configuration it can be provided, for example, that the light source in the case of a correct state of the chamfer emits a first color of light and that the source of light in a defective state of the chamfer emits a second color of light. Through the color of light the user can directly detect the condition of the chamfering machine.

Favorably, the light source of the signaling device can emit at least three different light colors, so that the user can not only differentiate a defective state from a correct state of the machine, but the user can be signaled by at least an additional light color other status information. It can be provided, for example, that a red light is emitted from the light source in the case of a defective state of the chamfering machine and white light is emitted from the light source, provided that the chamfer is in a reserve mode. If a machining mode is presented, then the light source can emit orange light, as long as no work piece is found in the chamfering machine between the machine inlet zone and the machine outlet zone, and the source of light can emit green light, as long as a work piece is currently found between the machine inlet zone and the machine outlet zone.

In the case of an advantageous configuration of the invention the brightness of the light source of the signaling device can be modified depending on the conditioner of the chamfering machine. Through different luminosities or light intensities the user can detect in particular, if a defective state or a correct state is present.

As an alternative or complement, it can be provided that the light source or flashes or lights continuously depending on the state of the chamfering machine. For example, in the case of a defective state the light source may flash and in the case of a correct state it may illuminate continuously. It is advantageous when the light source in the case of a defective state of the chamfer flashes with a first light color, for example with red light, and in the case of a correct state of the chamfer illuminates

continuously with a second color of light, for example with green light.

The flickering frequency of the light source can preferably be modified depending on the conditioner of the chamfering machine. For example, it can be provided that the light source flickers with low frequency, to signal to the user that the chamfering requires maintenance, because for example a stock of edge material or adhesive, which must be applied to the edge of the piece of work, it ends little by little. The flickering frequency can be increased, the more the reservation for example of edge material or for example of adhesive is finished.

For the configuration of the light source of the signaling device, no details have been described so far. Favorably, the signaling device has at least one laser source or at least one LED. Preferably, several light-emitting diodes are used, for example, in a row behind each other. As mentioned above, it is advantageous when the chamfering machine additionally presents a signaling device explained above with a monitor, in which state information of the chamfering machine is indicated to the user. The monitor offers in particular the possibility of displaying detailed status information, for example the status of each individual machining unit.

The monitor is preferably arranged above the machine inlet zone, for example on a front side of the chamfering machine. If a defective state of the machine is present, then this can be signaled to the user by means of the signaling device without using the monitor, by indicating the defective state in the machine entry zone on the transport device. The user can then interrupt the power of the machine and direct its view to the monitor, in order to obtain detailed information about the defective state.

The following description of a following embodiment of the invention serves for the more detailed explanation in relation to the drawing. They show:

The drawing schematically depicts an advantageous embodiment of a chamfering machine, which together is provided with the reference number 10. The chamfering machine 10 has a machine frame 12, in which machining units are arranged which are explained in more detail. detail below as well as a transport device 14. With the aid of the transport device 14 work pieces can be transported in the form of a plate, in particular wooden work pieces or materials that replace wood, for example chipboard, in a transport direction 16 from a machine inlet zone 18 to a machine outlet zone 20. The work pieces to be machined can be placed consecutively by a user in the machine inlet zone 18 on the transport device 14, and in the machine exit zone 20 the machined work pieces can be removed again from the transport device 14 In Figure 1 a first workpiece 21 and a second workpiece 22 are schematically represented. The work pieces 21, 22 have in each case a edge (narrow side) 23 or 24 oriented parallel to the transport direction 16, which can be machined by the machining units.

A first machining unit is configured in the exemplary embodiment represented as a lining unit 26, with the aid of which a edge material 28 can be fed in the form of a edge band 23 or 24 to be machined and fixed to the edge. Alternatively, a strip-shaped edge material could also be fed and fixed. Edge coating units of this type are known per se to the person skilled in the art. As a first machining unit, for example, a tool for machining with chip removal from edge 23 or 24 could also be used.

Other machining units of the chamfering machine 10 are configured as milling units 30, 32, saw unit 34 as well as polishing units 36, 38. Also units of this type are known per se by the person skilled in the art and do not require therefore in this case a more detailed explanation.

To display detailed information on the current state of the chamfering machine 10, this presents a monitor 40, which is arranged on a front side 42 of the chamfering machine 10 above the machine inlet zone 18.

To feed the chamfering machine 10 the user adopts a position on the side of the

transport device 14 opposite to the machining units next to the machine inlet zone 18 and deposits a new workpiece to be machined, as shown in Figure 2 and provided with reference number 44, towards the transport device 14, which can be equipped, for example, as a conveyor chain.

In the machine entry zone 18, the chamfering machine 10 has a signaling device 46 above the transport device 14, which signals the user the state of the chamfering machine 10 in the transport device 14. In the embodiment shown, the device Signaling 46 has a light source 48 with several light-emitting diodes, which are known to the person skilled in the art and therefore to achieve an overview in the drawing are not represented. A sector 50 of the transport device 14 diagonally from above is illuminated with the aid of the light source. The beam of light emitted by the light source 48, which widens as a wedge is schematically represented in Figure 2 and provided with the reference number 52. Since the light source 48 illuminates the sector 50 diagonally from above , the surface area of the workpiece 44 to be machined, located in the area of the sector 50, is also illuminated.

The light color of the light source 48 can be modified depending on the state of the chamfering 10. Depending on the state of the chamfering 10 the light source 18 emits light with different color of light. It can be provided, for example, that the light source 50 emits a red light, in the event that the chamfering 10 is in a defective state. By means of the sector 50 illuminated in this case in red, the user can directly detect that a fault occurs, without having to direct his sight to the monitor 40. In the case of a correct condition of the chamfering 10 the light source 48 In the embodiment shown, it emits a green light, when, as shown in Figure 1, at least one workpiece is already in the chamfering machine 10 between the machine inlet zone 18 and the machine outlet zone 20, and the light source 50 emits orange light in the case of a correct condition of the chamfering machine 10, as long as no work piece is found in the chamfering machine 10. Sector 50 is illuminated by the light source 48 with a color of additional light, for example with white light, as long as the chamfering machine 10 is in a reserve state, in which the machining units are not active.

Alternatively or in a complementary way, it can be provided that the luminosity (intensity) of the light source 48 can be modified depending on the state of the chamfering 10. The variation of the luminosity is particularly advantageous then, when by means of the light source 48 they can emit different colors of light. In case of failure, it can be provided, for example, that the light source emits red light with great intensity, while the light source in the correct state of the chamfering 10 emits, for example, green or orange light with lower intensity.

It can also be provided that the light source 48 flashes or illuminates continuously 10 depending on the state of the chamfering 10. A flashing can signal the user a defective state or for example a warning that the chamfering 10 requires maintenance, because for example the Reserve of a means of operation, for example a reserve of edge material or adhesive, which should be applied on a edge of the workpiece, is finished. In this sense, it can be provided that the flicker frequency of the light source 48 can be modified depending on the state of the chamfering 10. A low flicker frequency can signal the user, for example, a warning that maintenance is shortly needed. of the chamfering 10, and a high flicker frequency can signal a faulty state.
