Definitions
- the invention relates to a device for marking electrical devices which can be lined up and which are arranged on a mounting rail.
- the device has a receptacle for the mounting rail and a laser head to bring a marking on the electrical devices.
- Mounting rails are used to snap on electrical devices in installation technology. Especially in apparatus engineering, pre-assembled support rail sections are often used, which are then installed on site in control cabinets, which have a large number of electrical devices arranged next to one another. Among the electrical devices there are often series terminals, each of which in turn has a plurality of connections. In order to facilitate wiring of the arrangement within the switch box, the individual devices and their connections can be marked, for example by having corresponding marking areas.
- the publication WO 2010/057768 A1 shows a device with which the support rails can be equipped with electrical devices, in particular series terminals, in an automated manner.
- a printing unit is provided which prints an electrical device removed from a magazine on its marking surfaces before it is mounted on the mounting rail.
- the mounting rails are first fitted with the electrical devices and then the devices are marked.
- the cited document describes a marking device that has a mounting rail receptacle and a laser head that applies the desired markings on the marking fields of the devices.
- the mounting device for the support rail is coupled to a linear and swivel device so that the support rail with the electrical devices can be moved and pivoted in front of the laser head in order to be able to move the marking fields to be labeled into the labeling area of the laser head.
- mounting rails In large control cabinets or switchgear, mounting rails are used that have a length ranging from one to over one meter. In order to have a support rail section of this length with the above To be able to move direction in front of a laser head so that the laser head can reach the entire length of the mounting rail, a moving device is necessary whose length is at least twice the length of the mounting rail. In order to be able to process correspondingly long mounting rails, the device therefore requires a corresponding amount of space. As the length of the device increases, the expenditure on the stability and the quality of the guides of the displacement and swivel device increases in order to achieve a corresponding positioning accuracy and insensitivity to external or internal vibrations generated over the entire travel range.
- a device according to the invention for marking electrical devices of the type mentioned above that can be lined up in a row is characterized in that the receptacle is pivotably mounted about its longitudinal axis, and that the laser head is guided in at least one longitudinal direction that runs parallel to the longitudinal axis of the receptacle.
- the minimum necessary relative movements between the laser head and the devices to be marked are divided in such a way that the linear guide is carried out by the laser head, whereas the electrical devices are only pivoted but not moved.
- the receptacle for the support rails does not have to be able to carry out a movement over the entire length of the support rail, which means that the receptacle can be designed accordingly less long.
- a linear guide for the laser head, which now performs this displacement movement, can be arranged parallel to and next to the receptacle, so that the overall length is not increased as a result.
- the fixed arrangement of the pivotable receptacle, as well as the shorter design allows a solid design of this receptacle with less large SEM material outlay, so that the pivoting movement of high Rotationsbe acceleration can be carried out with low vibrations.
- the linear guide for the laser head also does not require a large amount of material, as it does not have to be designed for high torques and lateral forces that occur during the rotational acceleration of the swivel movement.
- the term “electrical device” is to be understood as any device with a mounting rail receptacle for arrangement on a mounting rail. These are, for example, purely passive series terminals, but also devices with switching or fuse elements, such as Automatic circuit breakers fall under the term “electrical device”, just like devices with electronic components that can be placed on a mounting rail.
- the receptacle has a longitudinal support with a receptacle bed for receiving the support rail, which is held eccentrically to an axis of rotation by pivot arms.
- the receiving bed is preferably arranged about 20 to 30 millimeters (mm) off-center from the center of the axis of rotation.
- the eccentric pivoting movement of the mount and thus the mounting rail is based on the knowledge that, on average, the center of gravity of the electrical devices to be labeled, especially in the case of terminal blocks, is about 20 to 30 mm above the mounting rail mount of the electrical devices. Due to the fact that the receiving bed is spaced from the axis of rotation by the abovementioned distance, the electrical devices are rotated on average in their own center of gravity, which enables a fast and inertia-free rotary movement. This minimizes the forces that occur when the rotary motion is accelerated. In this way, the highest possible rotational acceleration and thus swiftly executing swivel movement is achieved, which shortens the marking process overall.
- a sliding tab arranged to set mounting rails under different lengths can be provided in order to ne to reach over at their ends and be able to clamp in this way.
- the sliding tab allows devices to be marked on mounting rails of different lengths.
- electromagnets are arranged on or in the longitudinal support in the area of the receiving bed in order to hold the support rails on the receiving bed.
- a rotary leadthrough is preferably arranged on the receptacle in order to couple a power supply for the electromagnets.
- the use of permanent magnets or a combination of electro and permanent magnets is also conceivable to hold the mounting rail in the receiving bed.
- lateral guide plates run laterally on the receiving bed in the longitudinal direction of the longitudinal beam, and projecting beyond the plane of the receiving bed.
- the side guide plates are particularly helpful for longer mounting rails, as longer mounting rails for production and / or transport reasons tend to sag. Due to this deflection, the mounting rails and thus the electrical devices to be labeled would not be precisely positioned without the side guide plates.
- the side guide plates preferably protrude about 2 to 6 mm above the level of the receiving bed in order to laterally encompass the support rail in a lower area. In this area they do not collide with the latched electrical devices.
- the side guide plates are also preferably designed as spring steel plates so that they can compensate for tolerances in the width of the support rail.
- Support rails are usually rounded between their base and the upright sides, as they are typically manufactured as stamped and bent parts. Due to the radius, centering between the side guide plates takes place when the mounting rails are pressed onto the receiving bed. As a result of the type of fixing of the mounting rail described, mounting rails of different heights can also be used.
- the receptacle is also advantageously mounted in such a way that it can be pivoted through an angle of rotation greater than 360 ° without a stop.
- the angle of rotation is preferably also significantly greater than 360 ° and is, for example, 720 °. It can also be provided that any desired angles of rotation are possible without a stop.
- the rotary feedthrough is designed so that a power supply for the electromagnets can be provided for the entire range of rotation. The free pivotability achieved in this way makes it possible to move the mounting rail in any direction to swivel, and thus to switch to other labeling positions in every situation on the shortest possible rotation. This makes it possible to switch to the next labeling position in any case with a rotary movement of less than 180 °.
- a linear guide with a displaceable slide on which the laser head is mounted directly or indirectly is arranged parallel to the receptacle. Provision can be made for the laser head to be mounted on the slide via one or more further linear guides that run perpendicular to the linear guide.
- An additional additional linear guide in the horizontal direction makes it possible to bring the laser head at a suitable focus distance from the area to be marked, if the laser head does not have internal options for varying the focus distance.
- An additional linear guide in the vertical direction extends the marking area up and down.
- the laser head has a laser which emits in an ultraviolet (UV) wavelength range.
- UV wavelength range has the advantage that markings can be applied to almost any plastic surface.
- the electrical devices to be marked can have fields provided for marking, but these do not have to be provided with a special coating or a special plastic, as is usually necessary for markings with infrared (IR) light. It is also possible to apply markings to areas of the electrical devices that are not specifically designated.
- the markings applied can not only be pure color changes, but, when using suitable parameters and focusing the laser radiation, are accompanied by a material removal or a material modification that makes the markings palpable (tactile marking).
- Fig. 1 -4 an embodiment of a device for marking electrical devices rule, each in an isometric view from different directions of view and / or with different mounting rails used with the electrical devices to be labeled; 5a-c different views of a pivoting device of the marking device shown in FIGS. 1 -4; and

- Markiervor direction an embodiment of a device for marking stringable electrical devices, hereinafter referred to as Markiervor direction, is shown in an isometric view.
- the Mar kiervorraum is shown with a recorded support rail 1, on which a number of electrical devices 2 is locked. All of the latched devices 2 shown in the figures of this application are series terminals. It goes without saying, however, that other latched electrical or electronic devices such as fuses or load switches, for example, can be lined up on the support rail 1 and marked by the device shown.
- the electrical devices 2 are also referred to below as series terminals 2 for the sake of simplicity.
- FIG. 1, 2 and 4 show the marking device with differently equipped mounting rails 1.
- the viewing direction in which the device is shown is the same in the three cases mentioned.
- FIG. 3 shows the marking device with the mounting rail 1 and the terminal blocks 2 according to FIG. 2 from a different viewing direction.
- the marking device To receive and also to carry out a pivoting movement of the support rail 1 with the terminal blocks 2, the marking device has a
- Swivel device 10 on.
- the actual marking (labeling) on the terminal blocks 2 is carried out by a laser arrangement 20.
- the laser arrangement 20 will be described in more detail.
- the pivoting device 10 has a frame 11 in which a type of egg ner swing receptacle 12 is arranged rotatably about its longitudinal axis.
- the receptacle 12 comprises a longitudinal beam 13 which is arranged eccentrically at both ends via pivot arms 14 compared to an axis of rotation. This axis of rotation is rotatably supported in the bearings in the end parts of the frame 11 and coupled to a drive 16 to correspond.
- the drive 16 is, for example, an actuator with a position encoder.
- a DC motor that may be reduced in speed is particularly suitable for the actuating drive to achieve short positioning times.
- FIGS. 5a-5c which represent the pivoting device 10 in different views separately from the laser arrangement 20 and without a support rail 1 attached.
- Fig. 5a shows the pivoting device 10 in an isometric view
- Fig. 5b in a side view
- Fig.5c in a plan view.
- a fixed receiving tab 132 is arranged, under which an end portion of the support rail 1 is pushed in order to fix the support rail on the receiving bed 131 on this side.
- the opposite end of the support rail 1 is fixed with a comparable on receiving tab 152, which is not fixed, but is arranged on a slidable tab 15 ver.
- the rider 15 is guided longitudinally on the longitudinal beam 13, for which purpose, in this embodiment example, guide rails 135 are provided on the side of the longitudinal beam 13.
- the rider 15 is equipped with a quick release lever 151, which allows a locking of the rider 15 on the longitudinal beam 13 to be fixed or released. After releasing the tab 15, it can be moved in the direction of the attached mounting rail 1 until the mounting bracket 152 attached to the tab 15 (see FIGS. 5b, c) fixes the mounting rail 1 in the mounting bed 131.
- side guide plates 133 are provided in the longitudinal direction of the longitudinal beam 13 on the side edges of the receiving bed 131, which laterally guide the support rail 1 along its entire length.
- Fig. 6 a cross section through the longitudinal member 13 with a mounting rail 1 is shown.
- the side guide plates 133 grip around the support rail 1 laterally in a lower area.
- the side guide plates 133 are preferably designed as spring steel plates, so that they can compensate for tolerances in the width of the support rail 1.
- the side guide plates 133 are preferably made so thin and protrude only so far over the receiving bed 131 that they guide and position the support rail 1, but do not collide with latched-on electrical devices 2. This is possible because the mounting rail mounts on the electrical devices 2 usually have a Have a small lateral free space at least in the lower area of the mounting rail.
- the side guide plates 133 are particularly helpful for longer support rails 1, since production and / or transport-related longer support rails 1 tend to bend. Because of this deflection, an exact positioning of the mounting rails and thus the electrical devices to be labeled would not be possible or is achieved by the side guide plates 133.
- a plurality of electromagnets 134 are arranged at a distance from one another in the longitudinal direction of the support rail 13 in the receiving bed 131. After the mounting rail 1 has been placed on, the electromagnets 134 are energized individually, in groups or together, so that they fix the mounting rail 134 firmly and without a gap in the receiving bed 131 due to bending.
- a power supply for the electromagnet 134 takes place via a rotary feedthrough 17, which is preferably arranged on the side of the pivoting device 10 opposite the drive 16.
- FIG. 4 shows an example with a shorter support rail 1 used. In this case too, it can be provided that all electromagnets 134 are supplied with current. Alternatively, it can be provided to energize only a number of electromagnets 134 which are in the area of the actually used mounting rail 1.
- a channel running in the longitudinal direction of the longitudinal member 13 is formed in the longitudinal member 13, through which the cables for energizing the electromagnets 134 can run.
- the channel 136 also serves to reduce weight in order to minimize the rotational inertia of the receptacle 12 in order to achieve a high rate of rotation with the lowest possible torque.
- the receiving bed 131 for the support rail 1 is arranged eccentrically from the axis of rotation during the rotary movement.
- the distance by which the receiving bed 131 is spaced from the axis of rotation is preferably in the range of 20 to 30 millimeters (mm) and is particularly preferred pulls at about 23 mm.
- the reason is that, on average, the center of gravity of the electrical devices 2 to be labeled - in particular in the case of terminal blocks - is approximately 23 mm above the mounting rail mount of the electrical devices 2. If the receiving bed 131 is spaced apart from the axis of rotation by the distance mentioned, the electrical devices 2 are rotated on average in their own center of gravity, which enables a quick and as inertial rotation as possible. This minimizes the forces that occur when the rotary motion is accelerated. In this way, the highest possible rotational acceleration and thus quickly to be carried out
- the drive 16 and the rotary feedthrough 17 are preferably designed in such a way that an unlimited angle of rotation when the receptacle 12 is rotated is possible, please include. In this way, the rotating or pivoting movement of the receptacle 12 can take place at any time in any direction, unaffected by any other restrictions. The resulting advantages for the marking process will be explained in more detail later.
- the laser arrangement 20 is arranged laterally next to the pivoting device 10 in the region of the receptacle 12.
- the actual marking on the electrical devices 2, i.e. on the terminal blocks 2 in the example shown, is carried out by a laser head 21, which carries all the components necessary to apply the label, in particular a laser and deflection and possibly focusing units to the laser beam to be able to deflect the application of the marking, includes.
- Various techniques can be used to mark the electrical devices 2 with a laser.
- an infrared laser as the laser of the laser head 21, for example a CO2 laser that emits light with a wavelength of approximately 10.6 micrometers (pm).
- an infrared laser it is customary for marking surfaces sensitive to infrared radiation to be provided on the electrical devices 2 that change color when infrared laser radiation hits, so that a marking can be applied.
- the marking areas can be in the form of stickers, applied coatings and / or by using a corresponding infrared-sensitive plastic in the electrical devices in sections.
- a laser head 21 with a laser emitting in the ultraviolet wavelength range of approximately 190 to 380 nanometers (nm), in particular at 355 nm.
- a laser can be, for example, a Nd: YAG laser or also a CO2 laser with a subsequent frequency tripling.
- Light in the UV wavelength range has the advantage that markings can be applied to almost any plastic surface.
- the electrical devices can still have fields provided for marking, but these do not have to be provided with a special coating or a special plastic. It is also possible, please include, to apply markings to areas of the electrical devices that are not specifically designated. Through suitable parameters and focusing of the laser radiation, not only pure color changes can be used for marking, but material removal or material modification of the marked material can be achieved, which makes the markings palpable (tactile marking).
- the laser head 21 is controlled by a control device, not shown here, in order to apply a label within a focus field 4.
- the focus field 4 is shown in FIGS. 1-4. The exact size and the distance in which the focus field 4 is located in front of the laser head 21 are dependent on the imaging properties of the laser head 21.
- the laser head 21 can apply markings, in particular characters, digits and / or symbols, to areas to be marked.
- a laser beam generated in the laser head 21 is deflected via a plurality of rotatable or pivotable mirrors in order to reach every point in the focus field 4. Since the mirrors have a low mass inertia, the movement of the mirror and thus the deflection of the laser beam is a quick process compared to other mechanical movements in the system.
- the focus field 4 is smaller than the maximum length of the mounting rail 1 with the electrical devices 2 to be labeled.
- the laser arrangement 20 has a linear guide 22 in the longitudinal direction of the longitudinal member 13. This direction is also referred to below as the z direction.
- the linear guide 22 extends over the entire length of the receptacle 12 of the pivoting device 10.
- the linear guide 22 can for example be in the form of a spindle or rack and pinion drive. However, other drives are also possible. Because of For clarity, drive motors of the linear guide 22 are not explicitly shown in the figures.
- the laser head 21 is fastened to a movable slide of the linear guide 22 via a holder which enables the position of the laser head 21 to be adjusted in the x and y directions perpendicular to the z direction.
- a linear guide 23 is provided in the x direction and a linear guide 24 in the y direction.
- the x-direction runs horizontally and the y-direction runs vertically.
- the linear guide 23 can optionally be dispensed with and it can be designed as a holder with a fixed distance. If the variety of models of the electrical devices 2 to be labeled does not provide for large differences in height between the devices, it may be possible to dispense with a linear guide in the y-direction and the corresponding linear guide 24 can be designed as a fixed holder. The height difference relates to a variation in the distance between the areas to be marked and the mounting rail.
- marking planes 3 are drawn in which indicate the planes in which markings on the various rows 2 are to be attached.
- a plurality of identical terminal blocks 2 are arranged on the mounting rail 1, with areas to be marked being arranged on different sides of the terminal blocks 2 on contacts arranged at different heights (with respect to the mounting rail 1). All markings that can be applied to one or more of the terminal blocks 2 without either the receptacle 12 having to be pivoted or the laser head 21 having to be moved are recorded in a marking plane 3.
- the different marking levels are displayed one after the other
- Pivoting movement of the receptacle 12 or by using the linear guides 23, 24 in the x or y direction are possible, markings that may be required for longer mounting rails 1 are made after linear guidance of the laser head 21 in the z direction with the aid of the linear guide 22.
- FIG. 3 shows, due to the arbitrary pivotability of the recording 12, markings on the underside of the terminal blocks 2 are attached.
- the free pivotability also makes it possible to switch to the other side of the terminal blocks 2 via the underside of the side member 13. For example, if on both sides of the terminal blocks 2 obliquely downwardly inclined labeling fields are provided, a rotation over the bottom, i.e. a rotation in which the top of the terminal block 2 does not pass the laser head 21, but the underside of the longitudinal beam 13, would become one Perform a rotary movement of less than 180 ° instead of having to perform a rotary movement of more than 180 ° over the top.
