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 which 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 by means of the switch mechanism. Trigger function. This means that a machine equipped with the emergency stop switch is brought 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 operated switch and a first contact element that is operatively connected to the switch, the switch being configured for this purpose 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 mechanism with a switch tongue guided in a switch tongue guide, the switch tongue being configured to connect to a first end of a cable to be connected, wherein a switch tongue spring biases the switch tongue in operation in a direction facing away from the cable, and wherein the cable is connected with its second end to bias with a compensating spring during operation, the first contact element is operatively connected to the switch tongue such that the Switch tongue when pulling the proposed tensioned rope is guided in the tongue guide in the direction of the rope and against a spring force of the tongue spring and brings the first contact element into contact with the second contact element in order to trigger the emergency stop function by means of the cable mechanism.
  • the emergency stop switch thus provides two mechanisms for triggering the emergency stop function. This enables the emergency stop function to be triggered quickly and thus safely by an operator, which is adapted to the respective situation. Coupled with a machine, the emergency stop switch can be triggered manually by the operator of the machine or another person on the switch or the rope. As a result, the machine is switched from an operating mode to emergency stop in order to bring 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 near the cable, which can be used, for example, to cordon off an area. This increases the operability and security that the emergency stop switch will trigger the emergency stop properly.
  • the construction 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 switch tongue with the first end of the Rope is connected, is connected to bias with the balancing spring and the rope is connected with its second end to bias with the balancing spring.
  • the rope and / or the compensating spring can in particular be designed to be exchangeable.
  • the switch tongue can be connected to the first end of the cable. Furthermore, in particular, the switch tongue can be pretensioned in the direction facing away from the cable by means of the switch tongue spring. In particular, the second end of the rope can also be connected to a compensating spring during operation with a pretension.
  • the switch tongue can be placed against the switch 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 set up 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 means that the risk of the rope breaking can be reduced.
  • the switch tongue can be connected to a cable eye be.
  • the rope can be attached to the rope eye, which is particularly simple and safe.
  • a slide bearing can be arranged on the switch tongue guide. It enables the reed to slide in a defined and lubricated manner in the reed 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 in such a way that it can be moved along the switching tongue.
  • the actuator can in particular be designed to slide and / or roll along the switch 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 displaceably 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 actuator is designed as a drag roller.
  • the actuator can be designed as a sliding element, for example.
  • the drag roller can be made by a cylindrical Be formed body which is rotatably mounted on a longitudinal center axis of the cylindrical body.
  • the drag roller can be arranged such that it is in permanent contact with the first contact element and the switch tongue in the operating mode.
  • the drag roller can be mounted displaceably 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 actuator is arranged in a recess in the switch tongue.
  • the recess is designed in such a way that when the actuator is located in the recess, there is a distance between the first contact element on which the actuator rests and the second contact element.
  • the switch tongue is guided in its switch tongue guide and the actuator moves along the switch 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 made by pulling the cable is not interrupted when the rope is released. It is true that the switch tongue spring compressed by the pulling of the cable forces the switch tongue back into its starting position before the cable was pulled, that is, in the direction away from the cable. As a result, however, only the actuator moves back into the recess, while the first contact element continues to contact the second contact element. This ensures that the machine remains in emergency stop if the emergency stop function has been triggered by pulling the rope.
  • the switch of the switch mechanism In order to return to the operating mode of the machine or to switch off the emergency stop, the switch of the switch mechanism only needs 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 only resumed when safe operation is possible.
  • the recess has two flanks running obliquely to a longitudinal axis of the switch tongue. The actuator can be set up to move up along a first flank of the two flanks when the rope is pulled and / or along a second flank of the two flanks when the rope 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 switch tongue.
  • the two flanks can be arranged opposite one another.
  • the two flanks can run or rise in opposite directions.
  • the distance can be formed by a straight section on the switch tongue.
  • the flanks can in particular run obliquely to the longitudinal axis at an angle in the range from 15 ° to 75 °, in particular in the range from 30 ° to 60 °. This provides sufficient resistance to movement of 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, for the recess to correspond mathematically exactly to a trapezoidal shape.
  • the trapezoidal recess in this sense must therefore not only be formed from 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 makes it easy to use Actuator on a (straight or rounded) flank of the trapezoidal recess of the switch tongue.
  • the distance between the first contact element and the second contact element can be set as a linear function as a function of the guide path of the switch tongue, which enables a particularly simple design.
  • a line of symmetry of the trapezoidal recess can be in congruence with a first axis along which the switch mechanism acts. As a result, the actuator lies optimally in the recess.
  • the switch tongue spring is pretensioned.
  • the switch tongue spring can be preloaded with such a spring force that when the cable breaks the switch tongue leads the switch tongue in the switch tongue guide in the direction of the cable so far away that the actuator moves out of the recess.
  • the recess is trapezoidal and / or is designed with the two flanks running obliquely to the longitudinal axis. Because on a first flank of the trapezoidal shape, the functionality for the emergency stop function is provided by pulling the rope by the first actuator moving up along the first flank and moving the first contact element to the second contact element.
  • the functionality for the emergency stop function is provided by tearing the rope, in that the actuator moves up the second incline and the first contact element moves to the second contact element moved. Accordingly, it can be provided that the switch tongue spring is pretensioned with such a spring force that when the cable breaks, the switch tongue in the switch tongue guide leads so far away from the cable that the actuator moves along the second flank out of the recess .
  • a special feature here is that if the pretensioned switch tongue spring has been relaxed as a result of the rope breaking, the switch can no longer be reset or disengaged. Because the switch tongue is then returned in the opposite direction of the rope, so that the actuator can no longer get into the recess due to a lack of pretensioning of the rope and the switch tongue spring and blocks the retraction of the switch by being between the first contact element and the switch tongue. This prevents undesired operation of the machine in the run mode by resetting the switch if the rope is broken. As a result, the broken rope must first be replaced before operation can be resumed.
  • the switch is designed as a mushroom switch.
  • the mushroom head switch can be operated simply by pressing it in order to trigger the emergency stop function, whereby it engages in a pressed position.
  • the mushroom head switch can also be easily released by pulling it back in order to Stop to end or to set the operating mode, whereby it is disengaged.

  • the contact plate can, for example, be circular.
  • the switch tongue spring is designed as a spiral spring which is arranged concentrically around the switch tongue. This enables a particularly compact construction of the cable mechanism.
  • the switch tongue guide is formed in a switch tongue housing, the switch tongue housing having a contact section against which the switch tongue spring is applied.
  • the switch tongue spring can simply be compressed and tensioned when the cable is pulled in order to subsequently bring about a return of the switch tongue.
  • the formation of the contact section in the tongue housing also enables a compact construction of the cable mechanism.
  • the reed housing can consist of a first reed housing part and a second
  • the switch tongue can be fixed in the second switch tongue housing part by means of a fixation, for example by means of a dowel pin.
  • the fixation of the switch tongue by means of the dowel pin causes the second switch tongue housing part from the first
  • Switch tongue housing part is moved away when the cable is pulled. As a result, the switch tongue can be moved in a simple manner along the second axis.
  • a bellows can be arranged between the switch tongue housing parts, which bellows can expand and contract in order to follow the movement of the switch tongue and provide a dust seal.
