Abstract
The utility model relates to a novel grating protector, which comprises a master controller, a grating connected with the master controller through a signal cable, and a relay latching circuit, wherein the relay latching circuit comprises a relay and a switch button, a relay coil and the switch button are connected between a power source and the ground in series, and two contact ends of the relay are connected between the master controller and the grating in series. Through the relay latching circuit, a user only operates the button, so that a protection state and a non-protection condition of the grating protector are manually switched, and the novel grating protector has the advantages of convenience for use, flexibility and higher safety.
Description
Technical field
The utility model relates to a kind of grating protective gear, particularly a kind of manual switchover grating protection and novel grating protective gear of guard mode not realized.
Background technique
At the modern chemical industry factory, the human and computer collaborative work, have on the machinery of potential risk at some, such as punch machines, Cutting device, metal cutting equipment, automated assembly line, automatic welding line, mechanical transmission haulage equipment, deathtrap (poisonous, high pressure, high temperature etc.) etc., easily cause operating personnel's personal injury.The grating protective gear is installed is effectively avoided the generation of security incident, avoid operator and third-party danger.The grating protective gear produces protection light curtain by the emission infrared rays, and when the light curtain was blocked by obstacle, device sent shielding signals, and the machinery that control has potential risk quits work, and avoids occuring security incident.
Commissioning device etc. some in particular cases, need to suspend the grating protection, if directly deenergization can cause the infringement of equipment, so we just need to increase module and realize the protection of grating protective gear and the not switching of guard mode.At present, realize that the automatic switchover of grating protective gear need to be used PLC and touch screen, implement more complicated, need coding control, difficult grasp, and cost is higher.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of novel grating protective gear, can realize manual switchover grating protection and guard mode not, and easy to operate.
Following technical proposals is adopted in realization of the present utility model:
A kind of novel grating protective gear; comprise master controller and the grating that is connected with master controller by signal cable; also comprise relay latching circuit; described relay latching circuit comprises a relay and a switch button; this relay coil and this switch button are series between power supply and the ground, and relay two tip sides are serially connected between master controller and the grating.
Described grating comprises illuminator and light receiver, and above-mentioned relay two tip sides are serially connected with between illuminator and the master controller, perhaps between light receiver and the master controller.
Preferably, above-mentioned relay coil two ends are parallel with the tutorial light that is used to indicate the grating working state.
Preferred, above-mentioned relay coil adopts the single-pole double throw relay, and the relay common connects master controller, and normally-closed contact connects grating, and normally opened contact is by another tutorial light ground connection.
Compared with prior art; the beneficial effects of the utility model are: increase switching push button on original grating basis and can realize the protection of manual switchover grating and guard mode not; practical, easy to operate after changing, cost is lower; Security is higher, even if the malfunctioning rear grating of button still is in guard mode.
Description of drawings
Fig. 1 is the schematic diagram of grating protective gear described in the utility model.
Fig. 2 is embodiment's circuit diagram of relay latching circuit.
Among Fig. 1,1, grating; 2, master controller; 3, the button of relay latching circuit.
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, the novel grating protective gear that the utility model discloses comprises master controller 2 and the grating 1, the relay latching circuit that are connected with master controller by signal cable.Described grating 1 comprises illuminator and light receiver, and relay latching circuit comprises relay K M and switch button SB1, and switch button SB1 (label 3) is fixed on an end of light receiver.
As shown in Figure 2, the coil of the present embodiment repeat circuit KM and switch button SB1 are series between power supply and the ground, and relay K M tip side is serially connected between the light receiver of master controller and grating 1, control the break-make of the two signal.Relay K M coil two ends are parallel with the red led L2 that is used to indicate the grating working state.Relay K M adopts the single-pole double throw relay, and its common KM0 connects the master controller signal and receives line, and normally-closed contact KM1 connects the light receiver output line of grating, and normally opened contact KM2 is by green indicating lamp L2 ground connection.
SB1 is late for when switch button; the normal operation of grating protective gear; the grating protective gear is in guard mode; when between illuminator and the light receiver obstacle being arranged; light receiver receives the illuminator signal; then light receiver can send signal to master controller, and the corresponding machine of main controller controls quits work to protect lathe itself, also can protect obstacle (for example being the operator) not injured by lathe simultaneously.When switch button is pressed; the relay coil energising; red led lights; the relay normally-closed contact disconnects; common is connected with normally opened contact, and green indicating lamp is bright, and then the signaling path between light receiver and the master controller is truncated; grating enters not guard mode, can be used for the operations such as lathe maintenance this moment.
Master controller provides working power for grating sensor on the one hand; process on the one hand logical light, the shading status signal that grating sensor sends; utilize relay output connection, cut-off signal; be connected with the Stroke Control loop of press machine by control cables; or be connected with the safety protective circuit of other equipment, reach the purpose of protection personal safety.
Above-mentioned only is the more excellent mode of execution of the utility model; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection domain of the appended claim of the utility model.
