Definitions

  • the invention relates to an emergency stop switch and a machine with such an emergency stop switch.
  • Emergency stop switches known from the prior art typically have a switch mechanism.
  • the switch mechanism has a switch that is connected to a first contact element.
  • the switch is designed to bring the first contact element into contact with a second contact element when the switch is actuated in order to trigger an emergency stop function by means of the switch mechanism. This brings a machine equipped with the emergency stop switch to a standstill.
  • the object of the invention is to provide a simple, compact and safe emergency stop switch.
  • an emergency stop switch comprising: a switch mechanism with a manually operable switch and a first contact element rigidly connected to the switch, wherein the switch is designed to bring the first contact element into contact with a second contact element when the switch is actuated in order to trigger an emergency stop function, and a cable pull mechanism with a switching tongue guided in a switching tongue guide, wherein the switching tongue is designed to be connected to a first end of a cable, wherein a switching tongue spring pre-tensions the switching tongue in a direction facing away from the cable during operation, and wherein the cable is connected to a compensating spring with its second end in a pre-tensioned manner during operation, wherein the first contact element is operatively connected to the switching tongue in such a way that the switching tongue is guided in the switching tongue guide in the direction of the cable and against a spring force of the switching tongue spring when the pre-tensioned cable is pulled, thereby the first contact element comes into contact with the second contact element
  • an emergency stop function can be activated either by means of the switch mechanism by manually operating the switch or by means of the Cable pull mechanism can be triggered by pulling on the cable.
  • the emergency stop switch according to the invention therefore provides two mechanisms for triggering the emergency stop function. This enables the emergency stop function to be triggered quickly and safely by an operator, depending on the situation.
  • the emergency stop switch can be triggered manually by the operator of the machine or another person using the switch or the cable. This switches the machine from an operating mode to the emergency stop, bringing the machine to a standstill in a dangerous situation.
  • the cable pull mechanism provides another means of triggering the emergency stop function when the operator is not near the switch but is near the cable, which can be used to cordon off an area, for example. This increases the usability and security that the emergency stop switch will trigger the emergency stop correctly.
  • the switch mechanism and the cable pull mechanism are coupled to one another via the first contact element, the structure of the emergency stop switch according to the invention is compact and simple.
  • the operation refers to an operation of the emergency stop switch in which the switching tongue is connected to the first end of the cable, is connected to the balancing spring with pre-tension and the cable with its second end is connected to the balancing spring with pre-tension
  • the cable and/or the compensating spring can in particular be designed to be interchangeable.
  • the switching tongue can be connected to the first end of the cable. Furthermore, in particular, the switching tongue can be pre-tensioned in the direction facing away from the cable by means of the switching tongue spring.
  • the cable can also be connected to a compensating spring at its second end in a pre-tensioned manner during operation.
  • the shift tongue can be placed against the shift tongue spring.
  • the second contact element can be part of a switching unit.
  • the switching unit can trigger the emergency stop function when the second contact element is actuated.
  • the second contact element can be designed to switch an electrical contact of the switching unit and thereby trigger the emergency stop function.
  • the rope can in particular be designed as a wire rope. This makes the rope robust and resistant to mechanical damage, which can reduce the risk of the rope breaking. Furthermore, the switching tongue can be connected to a rope eye. The rope can be attached to the rope eye, which is particularly simple and safe.
  • a plain bearing can be arranged on the shift tongue guide. It enables the shift tongue to slide in a defined and lubricated manner in the shift tongue guide.
  • the first contact element and the switching tongue are operatively connected to one another by means of an actuator.
  • the actuator can in particular be designed such that it can be moved along the switching tongue.
  • the actuator can in particular be designed to slide and/or roll along the switching tongue.
  • the actuator can be arranged such that it is in permanent contact with the first contact element and the switching tongue in the operating mode.
  • the actuator can be mounted so that it can be moved in the direction from the switching tongue to the second contact element or, in other words, along a first axis along which the switching mechanism acts. By pulling the cable, the switching tongue is guided in its switching tongue guide and the actuator moves along the switching tongue and the first contact element, which in turn can move the first contact element in the direction of the second contact element.
  • the actuator is designed as a drag roller.
  • the actuator can be designed as a sliding element, for example.
  • the drag roller can be formed by a cylindrical body which is rotatably mounted on a longitudinal center axis of the cylindrical body.
  • the drag roller can be arranged in such a way that it is in the operating mode is in permanent contact with the first contact element and the switching tongue.
  • the drag roller can be mounted so that it can move in the direction from the switching tongue to the second contact element or, in other words, along a first axis along which the switching mechanism acts.
  • the switching tongue is guided in its switching tongue guide and the drag roller rolls along the switching tongue and the first contact element, which in turn can move the first contact element in the direction of the second contact element.
  • the actuator is arranged in a recess in the switching tongue.
  • the recess is designed in such a way that when the actuator is in the recess, there is a distance between the first contact element, against which the actuator rests, and the second contact element.
  • the switching tongue is guided in its switching tongue guide and the actuator moves along the switching tongue and is moved out of the recess. The distance between the first contact element and the second contact element is reduced until the first contact element finally meets the second contact element and triggers the emergency stop function.
  • the contact between the first contact element and the second contact element created by pulling the rope is not interrupted when the rope is released.
  • the switching tongue spring compressed by pulling the rope forces the switching tongue back to its original position before the rope was pulled, i.e. away from the rope. This only moves the actuator back into the recess, while the first contact element continues to contact the second contact element. This ensures that the machine remains in the emergency stop once the emergency stop function has been triggered by pulling the rope.
  • the switch on the switch mechanism only has to be pulled back or disengaged. This is because the first contact element is also connected to the switch, so that when the emergency stop function is triggered by pulling the rope, the switch is also actuated or engaged. This ensures that the operating mode is not resumed until safe operation is possible.
  • the recess has two flanks running obliquely to a longitudinal axis of the switching tongue.
  • the actuator can be designed to move along a first flank of the two flanks when the cable is pulled and/or along a second flank of the two Flank to move up when the cable breaks in order to move the first contact element to the second contact element.
  • the two flanks can in particular be formed on a common side of the switching tongue.
  • the two flanks can be arranged opposite one another.
  • the two flanks can run or rise in opposite directions.
  • the gap can be formed by a straight section on the switching tongue.
  • the flanks can in particular run at an angle in the range of 15° to 75°, in particular in the range of 30° to 60°, obliquely to the longitudinal axis. This provides sufficient resistance for moving the actuator.
  • the recess is trapezoidal.
  • the trapezoidal shape can have the flanks described above. In this sense, the recess represents a trapezoidal shape. It is advantageous but not necessary that the recess mathematically corresponds exactly to a trapezoidal shape.
  • the trapezoidal recess in this sense does not only have to be made up of straight lines, but can also have rounded lines and rounded corners, as long as it represents a trapezoidal shape in the broadest sense.
  • the trapezoidal shape enables the actuator to be easily moved on a (straight or rounded) flank of the trapezoidal recess of the switching tongue.
  • the distance between the first contact element and the second contact element can be defined as a linear function depending on of the guide path of the switching tongue, which allows for a particularly simple design.
  • a line of symmetry of the trapezoidal recess can be in line with a first axis along which the switch mechanism acts. This means that the actuator is optimally positioned in the recess.
  • the switching tongue spring is pre-tensioned.
  • the switching tongue spring can be pre-tensioned with such a spring force that when the cable breaks, the switching tongue spring guides the switching tongue in the switching tongue guide in the direction of the cable so far that the actuator moves out of the recess.
  • the recess is trapezoidal and/or has two flanks running at an angle to the longitudinal axis. This is because on a first flank of the trapezoid shape, the functionality for the emergency stop function is provided by pulling the cable, in that the first actuator moves up along the first flank and moves the first contact element to the second contact element.
  • the functionality for the emergency stop function is provided by breaking the cable, in that the actuator moves up the second slope and moves the first contact element to the second contact element. Accordingly, it can be provided that the switching tongue spring is pre-tensioned with such a spring force that, when the cable breaks, the switching tongue spring pushes the switching tongue in the switching tongue guide in the direction of the cable so far away causes the actuator to move out of the recess along the second flank.
  • a special feature is that if the pre-tensioned switch tongue spring has been released as a result of the cable breaking, the switch can no longer be reset or disengaged. This is because the switch tongue is then guided back in the opposite direction along the cable, so that the actuator can no longer reach the recess due to the lack of pre-tension in the cable and the switch tongue spring and blocks the retraction of the switch by being located between the first contact element and the switch tongue. This prevents the machine from being operated in unwanted mode by resetting the switch if the cable has broken. Consequently, the broken cable must first be replaced until operation can be resumed.
  • the switch is designed as a mushroom head switch.
  • the mushroom head switch can be easily operated by pressing it to trigger the emergency stop function, whereby it locks in a pressed position.
  • the mushroom head switch can also be easily released by pulling it back to end the emergency stop or to set the operating mode, whereby it is disengaged.
  • the first contact element is designed as a contact plate. This provides a large contact surface for contacting the second contact element is provided. Furthermore, the actuator can move particularly well on the contact plate.
  • the contact plate can be circular, for example.
  • the shift tongue spring is designed as a spiral spring that is arranged concentrically around the shift tongue. This enables a particularly compact design of the cable pull mechanism.
  • the shift tongue guide is formed in a shift tongue housing, wherein the shift tongue housing has a contact section against which the shift tongue spring is placed.
  • the shift tongue spring When placed against the contact section, the shift tongue spring can be easily compressed and tensioned when the cable is pulled in order to subsequently cause the shift tongue to reset.
  • the formation of the contact section in the shift tongue housing also enables a compact construction of the cable pull mechanism.
  • the shift tongue housing can be formed from a first shift tongue housing part and a second shift tongue housing part.
  • the shift tongue can be fixed in the second shift tongue housing part by means of a fixing, for example by means of a clamping pin.
  • the fixing of the shift tongue by means of the clamping pin causes the second shift tongue housing part to be moved away from the first shift tongue housing part when the cable is pulled. This allows the switching tongue to be moved easily along the second axis.
  • a bellows can be arranged between the switching tongue housing parts, which can expand and contract to follow the movement of the switching tongue and provide a dust seal.
  • the switching tongue has a support section on which the switching tongue spring is supported.
  • the support section can be designed as a circumferential thickening of the switching tongue.
  • the switching tongue spring can be supported against the support section by means of a disc spring. The switching tongue spring can thus simply be supported against the support section in order to enable compression. This also enables a compact design of the cable pull mechanism.
  • the switching tongue can have a guide pin guided in a longitudinal guide of the cable mechanism.
  • the guide pin can be guided in particular in a longitudinal guide of the switching tongue housing.
  • the longitudinal guide can be designed as an elongated recess in the switching tongue housing.
  • the guide pin can be arranged in particular on the support section. This prevents the switching tongue and the cable from twisting.
  • the compensating spring is firmly clamped in a clamping device during operation or is designed to be firmly clamped in a clamping device. This makes it easy to pre-tension the rope.
  • a first axis, along which the switch mechanism acts, and a second axis, along which the cable pull mechanism acts, are transverse, in particular orthogonal, to each other. This creates a compact structure in which both mechanisms interact with each other in a simple manner.
  • the switch mechanism and the cable pull mechanism are arranged in a common housing of the emergency stop switch.
  • the housing can also have at least one opening.
  • One opening can be intended for the switch, which can be mounted on the housing. In this respect, the switch can be easily operated from outside the housing.
  • another opening can be intended for the switch tongue guide, a switch tongue housing and/or the cable.
  • the switch tongue housing can also be mounted on the housing. This means that the cable can be easily pulled from outside the housing.
  • the switch mechanism can be attached to the housing, in particular screwed on, for example by means of a flange plate.
  • the cable pull mechanism can be attached to the housing in such a way that the switch tongue housing is inserted into the opening in the housing with a positive fit. This also enables a compact, safe and simple design of the emergency stop switch.
  • the switching tongue has a marking for setting a predetermined pre-tension of the cable, wherein the emergency stop switch has a viewing opening for reading the marking.
  • a predetermined displacement of the switching tongue can be set. This allows the pre-tension of the cable to be manually set to a predetermined or, in other words, correct value.
  • the marking can be a circumferential groove or color marking on the switching tongue.
  • the predetermined marking can be set when the marking is in a predetermined position that can be seen through the viewing opening. This position can be given, for example, when the marking is in the middle of the viewing opening. The point of the correct pre-tension can then be easily recognized or read using the marking if it can be seen in the middle of the viewing opening.
  • the viewing opening can, for example, be designed as a circular recess, in particular with a sight glass.
  • the viewing opening can in particular be designed in the switching tongue housing.
  • the object mentioned at the beginning is also achieved by a machine with the emergency stop switch, wherein the second contact element is connected to the machine in such a way that triggering the emergency stop function by means of the emergency stop switch causes the machine to come to a standstill.
  • the second contact element can be connected to a switching unit of the machine, as mentioned above, or the switching unit can be part of the emergency stop switch and can be connected to a power supply unit or another supply unit of the machine in order to trigger an emergency stop function.
  • the emergency stop switch 1 is located in the Fig. 1 in an operating mode.
  • the operating mode is a mode in which the emergency stop function is not triggered and a machine equipped with the emergency stop switch 1 is operating properly, in particular is supplied with power.
  • the emergency stop switch 1 has a housing 2.
  • a switch mechanism 10 and a cable pull mechanism 20 are accommodated in the housing 2 of the emergency stop switch 1.
  • the switch mechanism 10 has a switch 11, which in the present embodiment is designed as a mushroom head switch.
  • the switch 11 is rigidly connected to a first contact element 12 by means of a connecting part 13.
  • the first contact element 12 is designed as a round contact plate 12.
  • the switch 11 can be actuated in the direction X.1 along the first axis X.
  • the switch 11 When the switch 11 is actuated due to an emergency, the connecting part 13 and the first contact element 12 are moved in the direction X.1 along the first axis X. By moving the contact plate 12, it hits a second contact element 14 of a switching unit 15, which is arranged on a side wall of the housing 2. This triggers an emergency stop function. For example, in the case of a machine that is supplied with power, the power supply to the machine can be interrupted by executing the emergency stop function. This brings the machine to a standstill.
  • the switch 11 can be reset in the direction X.2 along the first axis X. This process releases the contact between the contact plate 12 and the second contact element 14, whereby the switching unit 15 enters the operating mode.
  • the cable mechanism 20 has a switching tongue 21 and a cable 30.
  • the switching tongue 21 is connected by means of a cable eye 29 is connected to the first end of the cable 30. Furthermore, the switching tongue 21 is guided in a switching tongue guide 22.
  • the switching tongue guide 22 is in this case formed in a switching tongue housing 23.
  • the switching tongue housing 23 encloses the switching tongue 21 in a section close to the cable 30 and leaves the switching tongue 21 free in a section remote from the cable 30.
  • a switching tongue spring 24 of the cable mechanism 20 is arranged concentrically around the switching tongue 21.
  • the switching tongue spring 24 is supported against a support section 25 of the switching tongue 21.
  • the switching tongue spring 24 is designed as a compression spring in the present case.
  • the support section 25 is designed as a circumferential thickening of the switching tongue 21.
  • the switching tongue spring 24 is placed against a contact section 26.
  • the contact section 26 is designed in the present case in a switching tongue housing 23.
  • the cable 30 is also connected at its second end to a compensating spring 31.
  • the compensating spring 31 is clamped in a fixed clamp 32.
  • the compensating spring 31 pre-tensions the cable 30.
  • the switching tongue spring 24 is compressed between the support section 25 and the contact section 26 and is thus pre-tensioned.
  • the switching tongue 21 further comprises a trapezoidal recess 27 with two flanks F.1, F.2 (see Fig. 2 ).
  • the cable mechanism 20 has a in operating mode in the trapezoidal recess 27 arranged actuator 28.
  • the actuator 28 is mounted so as to be displaceable along the second axis Y.
  • the actuator 28 is designed as a drag roller 28.
  • the drag roller 28 is mounted on the connecting part 13 of the switch mechanism 10.
  • the switching tongue 21 is pulled along its switching tongue guide 22 in the direction Y.2 along the second axis Y and against the spring resistance of the pre-tensioned switching tongue spring 24.
  • the switching tongue 21 is displaced in the direction Y.2 relative to the drag roller 28 and the contact plate 12.
  • the trapezoidal recess 27 with the switching tongue 21 moves opposite the drag roller 28 in the direction Y.2 along the second axis Y.
  • the drag roller 28 rolls onto the first flank F.1 of the trapezoidal recess 27 near the free end of the switching tongue 21 and thereby moves in the direction X.1 along the first axis X.
  • the drag roller 28 also rolls on the contact plate 12 and presses it in the direction of the second contact element 14 until the contact plate 12 and the second contact element 14 contact each other. This triggers the emergency stop function by means of the cable pull mechanism 20.
  • the switching tongue spring 24 which is further pre-tensioned against the spring resistance, presses the switching tongue 21 back in the direction Y.1 along the second axis Y until the drag roller 28 moves on the first flank F.1 and in the direction X.2 along the first axis X in order to reach the center of the recess 27 again.
  • the contact plate 12 remains on the second contact element 14, so that despite the cable being released, the operating mode does not start because the drag roller 28 is not firmly connected to the contact plate 12, but only contacts it when the emergency stop function is triggered.
  • the switch 11 In order to deactivate the emergency stop function or to return to the operating mode, the switch 11 must also be reset in the direction X.2 along the first axis X. This process releases the contact between the contact plate 12 and the second contact element 14, whereby the switching unit 15 enters the operating mode.
  • the emergency stop switch 1 In addition to triggering the emergency stop function by operating the switch 11 and pulling the rope 30, the emergency stop switch 1 has a third possibility of triggering the emergency stop function. This third possibility is if the rope 30 breaks. For safety reasons, the emergency stop function is activated in this case.
  • the pre-tension of the cable 30 by means of the compensating spring 31 on the switching tongue 21 no longer acts. This completely releases the pre-tensioned switching tongue spring 24, so that this pre-tension is also released and the switching tongue spring 24 guides the switching tongue 21 back as far as possible in the direction Y.1 along the second axis Y.
  • the drag roller 28 rolls along the second flank F.2 (see Fig. 2 ) of the trapezoidal recess 27 and presses the contact plate 12 against the second contact element 14, thereby triggering the emergency stop function.
  • the drag roller 28 is then located in the direction Y.2 along the second axis Y behind the trapezoidal recess 27 and between the switching tongue 21 and the contact plate 12. Unlike when the cable 30 is pulled, the drag roller 28 no longer returns to the recess 27 after the cable 30 is released, since there is no pre-tension available by means of the cable 30 that would guide the switching tongue 21 in the direction Y.2 along the second axis Y. Furthermore, the switching tongue spring 24 would also have to be overcome in order to bring the recess 27 in front of the drag roller 28. The drag roller 28 thus blocks the mushroom head switch 11 from being pulled back. For safety reasons, this prevents the emergency stop switch 1 from being unlocked if the cable 30 breaks. The broken cable 30 must be replaced in order to make the emergency stop switch 1 operational again so that it can be put into operating mode.
  • the switching tongue 21 is designed as an actuating bolt which is guided in the switching tongue guide 22 in the switching tongue housing 23.
  • the switching tongue 21 is provided with the cable eye 29 for connection to the cable 30 (see Fig. 1 ) tied together.

  • the flanks F.1, F.2 are formed in opposite directions obliquely to a longitudinal axis L of the switching tongue 21. Between the flanks F.1, F.2 there is a central section of the recess 27, which in the present case runs straight and in which the drag roller 28 is located when the cable 30 is not pulled and is not broken.
  • the switching tongue housing 23 is formed from a first switching tongue housing part 23.1 and a second switching tongue housing part 23.2.
  • the switching tongue 21 is fixed in the second switching tongue housing part 23.2 near the cable eye 29 by means of a clamping pin 33.
  • the first switching tongue housing part 23.1 is near the trapezoidal recess 27 and includes the switching tongue spring 24.
  • the fixing of the switching tongue 21 by means of the clamping pin 21, the second shift tongue housing part 23.2 is moved away from the first shift tongue housing part 23.1 when the cable 30 is pulled. This allows the shift tongue 21 to move along the second axis Y.
  • a bellows 35 is arranged between the shift tongue housing parts 23.1, 23.2, which can expand and contract to follow the movement of the shift tongue 21 and provide a seal against oil escaping from a sliding bearing 34 and the shift tongue guide 22.
  • the sliding bearing 34 is formed in the first shift tongue housing part 23.1 and enables the shift tongue 21 to slide in the shift tongue guide 22.
  • the support section 38 has a guide pin 38.
  • the guide pin 38 extends in a direction Z.2 along the third axis Z.
  • the guide pin 38 is guided in a longitudinal guide of the switching tongue housing 23, as shown in Fig. 1 is partially visible.
  • the longitudinal guide is designed as an elongated recess in the switching tongue housing 23, in particular in the first switching tongue housing part 23.1. This prevents the switching tongue 21 and the cable 30 from twisting.
  • the switching tongue housing 23 has a viewing opening 40 for reading a marking 21 arranged on the switching tongue 21.
  • the marking 21 is arranged at a position along the switching tongue 21, so that when the marking 21 is located in the middle of the viewing opening 40, a predetermined pre-tension of the cable 30 is set.
