Description

The invention relates to a workstation with a wall element having the features in the preamble of the main claim.

From practice, it is known to secure working and hazardous areas on robot cells and robotic systems by protective fences made of metal wire. The wall or fence elements used for this purpose are heavy, complex and expensive. They also require a considerable amount of assembly and handling. In addition, they can not be adequately adapted to local conditions.

The WO 97/35145 A1 shows a Maschineneinhausung with movable protective walls, which are formed by supports with running, motorized vertical blinds. The protective barriers block the worker's access to the machine and switch the power supply of the machine off or on depending on the position of the blind.

From the US 6,708,956 B1 is a safety fence around a robot cell with posts, wall panels, swing doors and an emergency exit known.

The DE 20 2011 002 081 U1 teaches a protective device of robot cells, consisting of a conventional protective fence and an additional separating element, which is arranged between protective fence and robot and is formed by framed networks with resiliently tensioned network wires.

The US 2012/0234510 A1 deals with mobile, roller-type retaining walls in the garden and landscape area to protect the environment from solid emissions and ejection of garden tools, especially grass or stone flight.

The DE 195 29 884 A1 relates to the vehicle sector and shows an illuminable, foil-like vehicle surface.

It is an object of the present invention to provide a better workstation with a wall element.

The invention solves this problem with the features in the main claim. The claimed wall element is provided to form a protective separation of the workstation and has several specific advantages.

The wall element can be used in different ways as a protective separation at a workstation. It can e.g. On the other hand, it can also be a hitherto customary fence on or around a working area, e.g. at a robot cell, replace.

The wall element offers on the one hand by its tensioned while tensile and strain-resistant wall material a high mechanical stability and dimensional stability to external loads. It can absorb these external forces or loads largely free from deformation. They can be removed via fasteners on an external support structure. By incorporating a reinforcing agent of the claimed type, the mechanical stability, in particular the cutting and breaking strength can be further increased.

On the other hand, the tension-resistant and stretch-resistant wall material can be designed to be flexible. It can be rolled or folded. In addition, the length of the extended and clamped wall material or of the wall element formed thereby can be varied. This is particularly advantageous in connection with a tensionable roller blind, which can be locked in different pullout positions. As a result, the wall element can be adapted to different local requirements.

The flexible wall element also has the advantage that it can be used to form a curved protective separation. This allows a particularly space-saving and customizable to a variety of purposes and locations training the wall elements or the protective separation formed therefrom or. Another advantage is the mobility of the claimed wall element, in particular in the form of a roller blind. For use, it can be taken off and stretched. On the other hand, it can be quickly reduced and in particular rolled up for a change of location.

The wall material advantageously has a tissue which can have a particularly high mechanical stability in all directions of its main plane. Alternatively, other material formations, e.g. as a foil or the like possible. A fabric also has the advantage that by incorporating high strength wires or filaments of metal, high strength plastics, e.g. Kevlar or the like., A stability increasing significantly reinforcing agent can be formed and integrated into the wall material in a simple manner.

The wall material can also be adapted to different application requirements. On the one hand, it can be translucent, whereby, for example, in the case of a woven fabric, a corresponding fabric structure with mesh-like free spaces is formed between the warp and weft threads. The Light transmission allows illumination of an area shielded from the wall element by an external light source. The translucent wall material represents a passive illumination.

On the other hand, the wall material may be opaque to provide optical shielding in addition to mechanical shielding. On the one hand, this can be favorable in order to avoid or reduce optical impairments and distractions of persons in the environment or when passing through a wall element. An optical shield may also be used to hide light effects, e.g. Flashlights, welding light or the like may be useful in a work area.

The claimed wall material, in particular a fabric, on the other hand allows printing. This can be for design purposes or even for the transmission of information. The wall material can also be colored in one or more desired shades.

The wall material can also have one or more additional functions in addition to a mechanically stable shielding.

On the one hand, it can have a transmission medium for a medium. This allows e.g. transmit electricity by means of an electrical line. On the other hand, a transmission means may be formed as a fluid line and transmit a liquid or gaseous medium for cooling purposes or other purposes.

Furthermore, it is possible to equip the wall material with an active illuminant, e.g. as flexurally elastic LED film or as a multilayer polymer film is formed.

The wall material may also include a signaling means. This can react to a disturbance and signal its occurrence. This can happen in particular optically. A signaling means may e.g. upon contact with an electrically conductive material, e.g. The metal fork of a forklift, close a circuit and activate a light bulb or other visual indicator. On the other hand, a signal means may have a limited mechanical load capacity and change its state in overload, in particular break or tear, which results in a physical reaction. For example, in a line, a colorant may be included, which emerges at line break and colors the wall material signaling. On the other hand, in the case of a break or an overstretch, an electrical resistance can be changed and a corresponding signal element can be switched in dependence thereon. A signal means may, in a further modification, comprise one or more sensors, e.g. Pressure transducer, exhibit. It can be designed, in particular, as a bending-elastic pressure measuring foil.

The one or more aforementioned reinforcement, transmission, signaling and lighting means may be integrated in the wall material. This can be done in different ways, e.g. by integration into a fabric or by a multi-layered design of the wall material. The various layers of material may possibly be connected to each other and thereby react to mechanical loads. The wall material may in particular have a protective layer, which is optionally equipped with a reinforcement. On the other hand, a functional position may be present which includes a transmission means and / or a signaling means. The number of layers can be two, three or more.

For attachment and mechanical support of the clamped wall material one or more edge-side fastening elements may be present. The clamping can be uniaxial. Particularly advantageous is the formation of a fastener as a roller blind housing. This can also provide a lock and support in different pullout positions or extension lengths of the blinds. The wall material can on the one hand have one or more free edges and be freely tensioned in this area.

The wall element and its wall material may be similar to a so-called support membrane or protective membrane in architecture, e.g. be formed when spanned tent roof. The wall element, despite attachment of the wall material only on a part of the edges or corners in the clamped state have a self-supporting function, which also absorbs the said external stresses and forces, thereby providing protection. It is also favorable that the expansion and tensile wall material also has a high resistance to breakage and tear.

In the subclaims further advantageous embodiments of the invention are given.

The wall element ( 2 ) may be used to form a protective separation ( 3 ) serve. A protective separation ( 3 ) can also consist of several wall elements ( 2 ) consist. A protective separation ( 3 ) can be used to shield different objects. You can also be seconded and trained in different ways. In the embodiments, various variants are given for this purpose.

1 and 2 show a workstation ( 1 ), which is a workstation ( 4 ) and a front access area ( 8th ) with a protective separation ( 3 ) having. The working device ( 4 ) contains eg one or more in 2 industrial robots shown within a protective device ( 6 ) and with a tool ( 5 ) edit a workpiece. The one or more industrial robots can execute any desired processes. This can be eg joining, application of materials, forming, mounting or handling or the like. A joining process may in particular be a welding process, especially a laser welding process.

The protection device ( 6 ) is designed for this purpose in a suitable manner to shield the working space to the industrial robot. In the embodiment shown, it is designed as a housing. In other variants, it can be designed as a fence, for example. The protection device ( 6 ), a lock ( 7 ) for the connection to the outside, in particular for the supply and the delivery of workpieces. In the illustrated embodiment, the lock ( 7 ) formed as a turntable, which can be manually operated by a worker or has its own drive and by means of an operating device ( 22 ) by the worker (not shown) can be triggered or operated.

The access area ( 8th ) opens at the front of the lock ( 7 ) and is open on the back, with a protective partition ( 3 ) is arranged. This consists of an upright wall element ( 2 ). The wall element ( 2 ) has one between vertical supports ( 9 ) uniaxial and in the horizontal direction stretched wall material ( 10 ), which is tensile and tensile strength and otherwise flexible formed. It has a very high resistance to breakage and tear, allowing it to roll or fold.

The wall material ( 10 ) has in the embodiments shown, the shape of a substantially rectangular material web, which in each case in the installed state vertical and opposite edges a fastener ( 12 . 13 ) having. About the fastener ( 12 . 13 ) is a fixed or detachable connection with a support ( 9 ) possible. An additional tightening of the wall material ( 10 ) in a second and in particular vertical direction is dispensable.

In the embodiment of 1 and 2 are the supports ( 9 ) on the one hand as free-standing vertical posts at the opening of the access area ( 8th ) and on the other hand as wall or corner elements of the enclosure ( 6 ) educated. On the free-standing supports ( 9 ), on the one hand, access control ( 21 ), for example a light barrier, and on the other hand, the aforementioned control device ( 22 ) can be arranged.

The wall material spanned in its main plane ( 10 ) is designed as a thin-walled web. In the embodiment shown is a fabric which has said tensile and tensile strength in all directions in its main plane. Alternatively, the wall material ( 10 ) Also made of another material, such as a film or other carrier material made of metal or plastic or the like. Exist, which has the aforementioned properties.

The preferably uniaxially stretched wall material ( 10 ) is self-holding and can absorb the externally applied mechanical loads and on the support (s) ( 9 ) ablate. The pillars ( 9 ) may be designed as tensioning cables or other support structures deviating from the rigid posts or wall elements shown.

Due to the self-holding and tensile and tensile strength training said two-sided fasteners ( 12 . 13 ) for clamping and stabilizing the wall element ( 10 ). In 1 and 2 can the horizontal upper and lower edges ( 14 ) of the wall material ( 10 ) are free and do not require contact with a support or fastener. You can alternatively be held on a channel or rod-like guide. In a further alternative modification, one or more additional fastening elements and a further clamping axis can be arranged here.

3 shows a variant of the wall element ( 2 ) and the protective separation ( 3 ). They serve here for shielding a working device ( 4 ), which is formed for example by an industrial robot. The wall element ( 2 ) or the protective separation ( 3 ) here forms an access protection, which prevents the access of persons in the working space of the industrial robot.

In the first embodiment of 1 and 2 shield the wall element ( 2 ) or the protective separation ( 3 ) the access area ( 8th ) of the worker against external influences and, together with access control ( 21 ), that during automatic operation of the lock ( 7 ) or feeding a person in the access area ( 8th ) is located.

In the variant of 4 form one or more wall elements ( 2 ) a protective separation ( 3 ) and access protection for a working device ( 4 ), eg an industrial robot. Between the here again vertical posts ( 9 ) can each have a wall element ( 2 ) with a horizontally stretched wall material ( 10 ) can be arranged. The wall elements ( 2 ) have a flat shape, as they are in 1 to 3 is shown.

4 also illustrates a variant with a curved wall element ( 2 ). Here, the bending elastic wall material ( 10 ) around one or more supports ( 9 ), thereby obtaining a curved shape in plan view.

The wall material ( 10 ) may be translucent or self-luminous. A light transmission can be achieved, for example, by a fabric with free spaces between the warp and weft threads. Alternatively or additionally, transparent and, for example, window-like material areas can be incorporated. The wall material ( 10 ) is preferably formed identically in its entire main plane. Alternatively, it may include locally different material designs. In a self-luminous training, the wall material ( 10 ) a light source explained below ( 18 ) exhibit.

The wall material ( 10 ) on the other hand can be opaque. It thus provides an optical shield. at 1 and 2 For example, the access area ( 8th ) are visually shielded to the outside, so that outside passers-by, for example, drivers of forklifts or other means of transport, not by visible operations in the access area ( 8th ) to get distracted.

The opacity can be combined with a light transmission, so that the wall material ( 10 ) has an opaque function similar to a frosted glass pane. Due to the passage of light from the outside, on the one hand the access area ( 8th ) and, on the other hand, said optical shielding is externally obtained. The wall material ( 10 ) may alternatively, in particular for other applications, be transparent or transparent.

The wall material ( 10 ), in particular in the form of a fabric, may also be printable. 2 shows such a print ( 23 ), which may serve advertising or information purposes or other purposes. It can be attached to the outside or inside. An imprint ( 23 ) can also only in a color on the surface of the wall material ( 10 ), which may be uniform or locally different.

The wall element ( 2 ) and in particular its wall material ( 10 ) may be designed rollable or foldable in the aforementioned manner. In 1 to 3 and 5 is the wall element ( 2 ) as a tensionable roller blind ( 11 ), which optionally also has a spring-loaded roll-up mechanism. The one fastener ( 12 ) can be formed for example by the dimensionally stable roller blind housing. The other fastening element ( 13 ) can be designed, for example, as a dimensionally stable fastening rod, which is suitably attached to the edge of the wall material ( 10 ), for example, in a looped loop or the like., Arranged and held. This can be a positive connection with a support device ( 9 ) according to 5 be formed.

The blind ( 11 ) can have a fixed and predetermined extension length. In another embodiment, the roller blind ( 11 ) variable in length and can fix in different extension lengths in a suitable manner and lock. For this purpose, the roller blind ( 11 ) have suitable locking mechanisms on the winding device. A length variability of the wall element ( 2 ) is also in other and by a roller blind ( 11 ) deviating constructions, such as a folding construction, possible.

In a modification of the Ausführungsbeipsielen shown with the horizontal extension and clamping direction of the wall element ( 2 ) or the wall material ( 10 ) is also a vertical or oblique pull-out or clamping direction possible. The wall element ( 2 ) can also be arranged horizontally or obliquely with its main plane.

Furthermore, the wall material ( 10 ) have a different form of cut. This can be triangular, for example. In this case, for example, at a triangular side and at the opposite corner or tip each a suitably suitable and trained fastener ( 12 . 13 ) to be available. The edges of the wall material ( 10 ) preferably have a straight extension.

The wall material ( 10 ) a reinforcing agent ( 15 ) to increase the mechanical stability. The reinforcement ( 15 ) can be formed, for example, by one or more wires, threads or by one or more fabrics, meshes or the like, which consist of a mechanically particularly stable material, in particular metal or high-strength plastic fibers. 2 illustrates, for example, an arrangement of a plurality of wires or threads, which are arranged in the extension or clamping direction.

The wall material ( 10 ) may alternatively or additionally comprise a transmission means ( 16 ) for a medium. The transmission means ( 16 ) may have, for example, an electrical line for transmitting power and / or signal currents. Such a conduit can also have a reinforcement function and provide for a higher mechanical stability. The cable shield may suitably be provided by an insulating sleeve or alternatively by the wall material ( 10 ) respectively.

In another variant, the transmission means ( 16 ) have a fluid conduit that transports liquid or gaseous fluids. This can be, for example, compressed air, a coolant or lubricant or the like. Such a fluid may also be a colored liquid. The transmission means ( 16 ) can also advantageously along the extension and clamping direction of the wall material ( 10 ), as stated in 2 is indicated.

In further alternative or additive variation, the wall material ( 10 ) a signaling means ( 17 ) exhibit. The signal means ( 17 ) can react in particular with a disturbance influence and signal the disturbance influence in a suitable manner. A disturbance influence can be, for example, a mechanical load, in particular an overload, of the wall material ( 10 ) be. Such a load or overload arises, for example, if according to 3 the industrial robot ( 4 ) by a malfunction with his tool or with a robot part against the wall element ( 2 ) and the stretched wall material ( 10 ) thereby subjected to elongation and tension.

Another interference influence may be an undesired mechanical or in particular also current-conducting contact with an external object. In this case, for example, a metallic fork of a forklift may be the wall material ( 10 ) to contact. Furthermore, it is possible that a current-carrying cable, a broken fluid line or the like. In contact with the wall material ( 10 ) comes.

The reaction of the signaling agent ( 17 ) can be designed differently. For example, grounding can occur due to a metallic contact and a circuit can be connected to the signal medium ( 17 ) adjacent electrical potential. In the event of mechanical overloading, an expansion of the signal means ( 17 ), which may result in an electrical resistance change when the signal means ( 17 ) has a current-carrying conductor. Furthermore, it is possible that the signal means ( 17 ) breaks or breaks under load or overload, for example, one in the signal means ( 17 ) contained medium, such as a dye exits. These reactions of the signaling agent ( 17 ) move in a load range in which the mechanical stability of the wall material ( 10 ) continues to exist. The signal means ( 17 ) but also reacts when under extreme overload and the mechanical tear or breaking strength of the wall material ( 10 ) should be exceeded.

The signal means ( 17 ) can signal the influence of interference, which may be an optical display, for example. The above-mentioned, by line break emerging dye can, for example, the wall element ( 10 ) and thereby signal the disturbance. On the other hand, the aforementioned short circuit, the resistance change or another electrical reaction can be recorded by a suitable detection means and signaled via a display, eg a warning light, a signal tone or the like. In addition, other arbitrary other configurations of the signaling device ( 17 ) possible.

In a further alternative or additive modification, the wall material ( 10 ) a light source ( 18 ) exhibit. This can be, for example, an arrangement of one or more LEDs or other light-emitting elements. These can be present in a single arrangement or in a composite, for example in the form of a so-called LED film or a multilayer polymer film. Such a light source ( 18 ), for example in the form of individual LEDs in 1 can be used for active illumination of the access area ( 8th ) or shielding area. A light source ( 18 ) can also be used as a display means or signal means. In particular, via a light source ( 18 ), which is equipped, for example, with OLEDs or with liquid crystals or the like, transmit or display information in graphic or alphanumeric manner.

The aforementioned bulbs ( 15 . 16 . 17 . 18 ) can be present singly or multiply and in any combination. You can put in the wall material ( 10 ) be integrated. For example, high-strength metal or plastic threads in the wall material ( 10 ) woven in. The same applies to thin electrical or fluidic lines.

Alternatively, one or more of the means ( 15 . 16 . 17 . 18 ) on the outside wall material ( 10 ). According to 1 For example, several LEDs ( 18 ) on the wall material ( 10 ) glued on the outside or fastened in another way.

As 6 clarifies, the wall material ( 10 ) one or more layers ( 19 . 20 ) exhibit. In the example, two layers ( 19 . 20 ). The number of layers can also be three or more.

The wall material ( 10 ) can eg a protective layer ( 19 ), which consists of said fabric or another tensile and tensile strength material. The protective layer ( 19 ) may also contain a reinforcing agent ( 15 ).

Another and especially second situation ( 20 ) a functional position ( 20 ) and may be another means, eg a means of transmission ( 16 ) and / or a signal means ( 17 ) and / or a light source ( 18 ) exhibit. The functional position ( 20 ) may have a different strength than the protective layer ( 19 ) and thereby react in the manner described above on interference, in particular mechanical loads. The layers ( 19 . 20 ) may be interconnected along their major plane, eg, over the entire surface, pointwise or line by line. The layers ( 19 . 20 ) can alternatively only at the edges and in particular on the fastening means ( 12 . 13 ) be interconnected.

The wall element ( 2 ) is in the manner described above as a protective separation ( 3 ) for a work or access area ( 8th ) educated. It can be made stationary or mobile. The wall element ( 2 ) or the protective separation ( 3 ) can be installed and dismantled quickly and easily as needed. In particular, a roller blind ( 11 ) quickly with its fastener ( 12 ) on the support ( 9 ) are hung and rolled up. The same applies to a foldable wall material ( 10 ).

At the in 1 In this embodiment, the workstation ( 1 ) be placed in a quick and easy way between different locations using forklift, crane or the like. Only the individual posts or columns ( 9 ) must still be dismantled and rebuilt at the other site, then the blind ( 11 ) again for the production of the protective separation ( 3 ) is pulled out and stretched.

The same applies to the in 3 and 4 shown protective separation ( 3 ) for the working space of an industrial robot ( 4 ). In this design, it replaces the usual rigid metal fences. Again, the easy disassembly and the mobility of the protective separation ( 3 ) or its one or more wall elements ( 2 ) advantageous for use.

Variations of the embodiments shown and described are possible in various ways. On the one hand, the features of the exemplary embodiments can be combined with one another as desired and, if necessary, swapped over. Furthermore, constructive modifications of the means ( 15 . 16 . 17 . 18 ) possible in addition to the aforementioned variants.
