The utility model provides a scram switch which can be used for various automatic equipment, and can facilitate an operator to shut down the automatic equipment in time through the scram switch under the critical condition that the operator is in misoperation or the automatic equipment is out of control, so that safety accidents are avoided.
Referring to fig. 1, the emergency stop switch provided by the utility model includes a connection seat 10, a sensing switch 20, a sensing member 30 and a pull wire 40, wherein the connection seat 10 is arranged on or near an automation device, the sensing switch 20 is arranged on the connection seat 10 or at a side of the connection seat 10, the sensing member 30 is connected to the connection seat 10 and is close to a sensing end of the sensing switch 20, one end of the pull wire 40 is fixed to the sensing member 30, and the other end is fixed to a preset fixed point 110.
The inductive switch 20 is arranged on a power circuit of the automation equipment, the inductive piece 30 can be connected to the connecting seat 10, the inductive piece 30 can be close to an inductive end of the inductive switch 20 in a connection state, and when the inductive piece 30 is sensed by the inductive switch 20, the inductive switch 20 is kept in a conduction state, so that the power circuit of the automation equipment normally works.
The connection mode of the sensing piece 30 and the connecting seat 10 can adopt magnetic connection, that is, the sensing piece 30 and the connecting seat 10 are made of magnetic materials. For example, the connection base 10 is made of a magnet, the sensing piece 30 is made of iron or steel, and the sensing piece 30 can be magnetically attracted to the connection base 10, and meanwhile, the magnetic connection between the sensing piece 30 and the connection base 10 can be released under the action of external force.
The pull wire 40 is used to provide power for disconnecting the sensing element 30 from the connector holder 10. One end of the stay wire 40 is fixed on the sensing element 30, and the other end is fixed on a preset fixed point 110, so that the stay wire 40 is arranged along a proper path, and can be kept in a straightened state, and the stay wire 40 is convenient to bear force.
Referring to fig. 2, under critical situations, a worker may trigger the pull wire 40 by hand, foot, etc. to pull the sensing element 30 from the connection base 10. At this time, the sensing piece 30 is far away from the sensing end of the sensing switch 20, so that the sensing switch 20 can not sense the sensing piece 30 and is turned into a disconnected state, and then the power circuit of the automation equipment is disconnected, the operation of the automation equipment is stopped in time, and the operation safety accident is avoided.
After the danger is relieved, the worker can magnetically adsorb the sensing piece 30 on the connecting seat 10 again, so that the sensing switch 20 is turned on again, and the normal operation of the power circuit of the automatic equipment is restored.
Besides, besides the magnetic connection, the connection seat 10 and the sensing piece 30 can also adopt a clamping connection mode. Corresponding clamping structures, such as a buckle and a clamping hole which are matched with each other, are respectively arranged on the connecting seat 10 and the sensing piece 30, the connection between the connecting seat 10 and the sensing piece 30 is kept in a clamping fit mode, and the clamping fit is released when the pull wire 40 applies a pulling force, so that the sensing piece 30 is separated from the connecting seat 10.
Compared with a scram button fixed at one position, the pull wire 40 can be provided with a proper path and length, so that the triggering range of the scram switch is effectively enlarged, workers can easily find the pull wire 40 at critical time and shut down the automation equipment by triggering the pull wire 40, and the safety of the automation equipment during operation is greatly improved.
In some embodiments, the sensing element 30 is rotatably disposed at the preset rotation point 120, and one end of the pull wire 40 is fixed to the sensing element 30 and drives the sensing element 30 to rotate around the preset rotation point 120.
When the pull wire 40 pulls the sensing element 30 to rotate around the preset rotation point 120, the connection between the sensing element 30 and the connection seat 10 can be disconnected, and meanwhile, the movement of the sensing element 30 is limited by the preset rotation point 120, so that the sensing element 30 and the pull wire 40 cannot be pulled to other positions by a worker. After the dangerous situation is relieved, the worker only needs to rotate the sensing piece 30 again to know the sensing piece 30 and the connecting seat 10 again, and then the normal state of the scram switch can be recovered.
In some embodiments, the sensing element 30 includes a rotating portion, a sensing portion, a connecting portion and a fixing portion, wherein the rotating portion is rotatably disposed at the preset rotating point 120, the sensing portion is proximate to the sensing end of the sensing switch 20, the connecting portion is magnetically connected or snapped or adhered to the connecting base 10, and the fixing portion is fixedly connected to the pull wire 40.
The rotating part and the fixing part are arranged at the two ends of the sensing piece 30, so that a worker pulls the sensing piece 30 through the stay wire 40 more easily, and the situation that the sensing piece 30 cannot rotate is avoided. In addition, the connecting part approaches the fixing part, so that the sensing piece 30 in a normal state is not easy to separate from the connecting seat 10.
Further, the preset rotation point 120, the inductive switch 20 and the connection base 10 may be sequentially disposed upward along the vertical direction, that is, the inductive piece 30 is integrally connected to the connection base 10 in a vertical posture. When the pull wire 40 pulls the sensing element 30 outwards, the sensing element 30 will naturally fall down due to the gravity rotating along the preset rotation point 120, so as to ensure that the sensing element 30 will not be sensed by the sensing switch 20.
The overall shape of the sensing member 30 can be set according to actual needs. For example, the sensing member 30 may be configured as a flat plate, and the preset rotation point 120, the sensing end of the sensing switch 20, and the connection end of the connection seat 10 are disposed on the same plane, so that the overall structure of the scram switch is more concise. Of course, the sensing element 30 may be configured in other configurations, such as a curved configuration or a stepped configuration, as desired.
In some embodiments, referring to fig. 1 and 2, the scram switch further includes a buffer spring 50, wherein the buffer spring 50 is disposed on the wire 40 along a radial direction of the wire 40.
The buffer spring 50 is used for extending the length of the stay wire 40 when the stay wire 40 is stressed, so that the stay wire 40 is not easily broken by stress, and the service life of the stay wire 40 is protected.
Further, the number of the buffer springs 50 may be two, wherein one buffer spring 50 is close to the sensing member 30, and the other buffer spring 50 is close to the preset fixed point 110.
Because the stress points of the stay wire 40 are positioned at the two ends of the stay wire 40, the two buffer springs 50 are respectively arranged at the two ends of the stay wire 40, so that the impact can be relieved to a greater extent, and the stay wire 40 is prevented from being broken.
In addition, referring to fig. 3, the present utility model further provides a protection mechanism, which includes a fence 100 and the above emergency stop switch, wherein a preset mounting point 130 and a preset fixing point 110 are disposed on the fence 100, the connection base 10 and the inductive switch 20 are disposed at the preset mounting point 130, and the other end of the pull wire 40 is disposed at the preset fixing point 110.
The enclosure 100 encloses a processing area in which the automation equipment can be located, leaving a roadway between the automation equipment and the enclosure 100 for personnel to walk. The emergency stop switch can be arranged on the inner side surface of the fence 100, so that workers working in a roadway can conveniently trigger the emergency stop switch to stop the automation equipment.
The connecting seat 10 and the inductive switch 20 can be fixed on the preset mounting point 130 by means of threaded connection and the like, and fixing pieces such as pull rings can be arranged at the preset fixing point 110, and the pull wire 40 is bound on the fixing pieces. The preset rotation point 120 may also be disposed on the fence 100, and a rotation shaft is disposed at the preset rotation point 120, and the sensing element 30 is sleeved on the rotation shaft, so that the sensing element 30 can rotate around the rotation shaft.
In some embodiments, the stay 40 is disposed along the side of the fence 100, which can effectively utilize the space in the fence 100, increase the triggering range of the stay 40, and prevent the stay 40 from interfering with the normal operation of the automation equipment.
And, the number of the emergency stop switches can be set to be two or more, and each emergency stop switch is arranged on different inner sides of the fence 100, so that the emergency stop triggering range in the roadway is further covered, and the safety of personnel is comprehensively protected.
Specifically, taking the case that the protection mechanism is applied to the stacker 200 as an example, the rail 100 is generally provided with the ground rail 300, the stacker 200 capable of moving along the ground rail 300 is arranged on the ground rail 300, and meanwhile, the travel limit posts 400 are arranged on two sides of the ground rail 300 to avoid the movement over travel of the stacker 200.
When a worker works in the fence 100, because the stacker 200 is operated at a high speed, the space in the operation roadway of the stacker 200 is very small, and once the operation of the stacker 200 is out of control or the operation of the worker is wrong, the worker in maintenance or construction in the roadway is at a risk. If the stacker 200 approaches to the critical situations such as self or collision, a worker can quickly trigger the stay wire 40 on the fence 100 through the parts such as hands and feet, and the inductive element 30 is separated from the connecting seat 10 through the stay wire 40, so that the inductive switch 20 cannot sense the inductive element 30 and is disconnected, and then the power supply of the stacker 200 is turned off, and at the moment, the stacker 200 can stop immediately, so that the occurrence of the accident that the stacker 200 hurts people is avoided.
