Abstract
The utility model discloses an order travel switch emergency exit system, including emergency exit and emergency exit lock, be provided with the travel switch and the 2nd travel switch that contact in proper order with it in the closing stroke of emergency exit lock, a travel switch and the 2nd travel switch are connected with the control system electricity respectively, control system receives a travel switch and the 2nd travel switch's signal in order. The utility model relates to a machine operation personnel's the security and the security of machine through two travel switch's protection, have been improved greatly in injection molding machine mechanical equipment field, avoid causing the accident because of travel switch's malreduction.
Description
Technical field
The utility model relates to injection machine technical field of mechanical equipment, particularly relates to a kind of order stroke switch safety door system.
Background technology
Injection machine is provided with safety device usually to protect the safety of people, machine, and safety device is primarily of compositions such as safety door, safety screen, hydraulic valve, limit switches.And run time, particularly close mould time, safety door needs to be in closed condition, prevents human body from entering mould zone of action and damages; When safety door is opened, provide activity space to the fixing of mould and dismounting, also facilitate the maintenance of machine simultaneously.Current safety-door device adopts one-stroke switch control rule; or normal series connection travel switch of making war controls, but such scheme shortcoming is, one-stroke switch safety is low; series connected control safety coefficient increases, but can not play a protective role when forming switch malreduction.
Utility model content
In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art, the order stroke switch safety door system providing a kind of security high.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize:
A kind of order stroke switch safety door system, comprise safety door and safety door lock, the closing stroke of described safety door lock is provided with the first travel switch and the second travel switch that contact successively with it, described first travel switch and the second travel switch are electrically connected with control system respectively, and described control system receives the signal of the first travel switch and the second travel switch in turn.
During closed safe door; first travel switch first closes; second travel switch closes again; control system receives only by the first travel switch first sequential signal of closing again of closed second travel switch; if wherein some travel switch strokes damages, the signal sequence that control system receives is not right, then can alarm; control machine quits work by control system, and the technical program ensure that machine has the protection of two switches for a long time.
Also comprise the first signal detector and secondary signal detector, described first signal detector is electrically connected with the first travel switch and control system respectively, and described secondary signal detector is electrically connected with the second travel switch and control system respectively.
Whether the first signal detector and secondary signal detector normally work for detecting corresponding travel switch, when detecting that corresponding travel switch is in abnormal operating state, control system obtains the signal of detector and demonstrates corresponding travel switch, is convenient to maintenance personal and carries out long-range monitoring and keep in repair fast.
First travel switch is arranged on the casing corresponding with safety door lock with the second travel switch.
Compared with prior art, the utility model has following beneficial effect: by the protection of two travel switches, substantially increases the security of operating staff and the security of machine, avoids causing the accident because of the malreduction of travel switch.
Accompanying drawing explanation
Fig. 1 is embodiment 1 structural representation;
Fig. 2 is embodiment 1 schematic diagram.
Detailed description of the invention
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further elaborated.
Embodiment 1
As shown in Figure 1, a kind of order stroke switch safety door system, comprise safety door 1 and safety door lock 2, the closing stroke of described safety door lock 2 is provided with the first travel switch 3 and the second travel switch 4 contacted successively with it, described first travel switch 3 and the second travel switch 4 are electrically connected with control system (not marking in figure) respectively, and described control system receives the signal of the first travel switch 3 and the second travel switch 4 successively.
As shown in Figure 2, also comprise the first signal detector and secondary signal detector, described first signal detector is electrically connected with the first travel switch and control system respectively, described secondary signal detector is electrically connected with the second travel switch and control system respectively, and whether the first signal detector and secondary signal detector normally work for detecting corresponding travel switch.
Described first travel switch 3 and the second travel switch 4 are installed on the corresponding casing of safety door lock 25.
