The safety protection device comprises a photoelectric detector, a main controller, a buffer, a self-checking circuit, and a machine tool controller. The photoelectric detector is connected with the buffer and the main controller, the buffer and the self-checking circuit are connected with the main controller, the main controller is connected with the machine tool controller, the machine tool controller is connected with an emergency stop, the main controller is connected with an alarm unit, and the alarm unit comprises a detector, a controller, and a communication module. The detector, the detector, and the controller are connected via leads, and are an alarm part. The controller of the alarm part is connected with the communication module via a lead.

Description

A kind of lathe safety guard with remote alarms

Technical field

The utility model relates to a kind of safety guard of automatic machine tool, specifically relates to a kind of lathe safety guard with remote alarms.

Background technology

Along with manufacturing day by day flourishing, produce machine, equipment is increasing, but the design of a lot of machinery equipments, in manufacture and actual production, exist more unpredictalbe potential safety hazard, some lathes need watchful manual operations, people are when operating them, once unless you give your whole attention to it, will cause unexpected injury to operator, the interests of manufacturer have not only been damaged, more unfortunately very on victim's health and cause mentally permanent injury, a lot of machinery equipments all can reach higher personal safety by Late reformation and protect, thereby avoid more security incident.Existing protective device is all to control machine by simple signaling zone, and once the circuit of self breaks down, can there is uncertain fearful phenomenon, operator thinks safety system, when operation, can reduce vigilance, once there is accident, will cause indelible injury to the person; On some markets, also have the higher automated machine tool of some securities now, but this machine tool technology adopts the monopolization technology of offshore company mostly, the price of lathe is high, and safety device selectivity is strong, portable poor.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides the purpose of this utility model to be just to provide a kind of simple in structure, and security is good, the lower-cost lathe safety guard with remote alarms.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of lathe safety guard with remote alarms, comprise photoelectric detector, master controller, buffer, self-checking circuit and machine tool controller, described photoelectric detector is connected with master controller with buffer, buffer is all connected with master controller with self-checking circuit, master controller is connected with machine tool controller, on machine tool controller, be connected with an emergency stop switch, on described master controller, connect an alarm unit, described alarm unit is by detector, controller and communication module form, detector, detector is connected by wire with controller, for alarm part, on the controller of alarm part, pass through wire connecting communication module.

Preferably, described photoelectric detector is infrared detector.

Preferably, on described buffer, connect a position detector.

Advantage of the present utility model and beneficial effect are: the utility model circuit structure is simple, easy to use, security is good, and cost of manufacture is lower, practical, when operator's hand stretches into deathtrap, this communication, in master controller, is then analyzed this information by master controller, and the emergency stop switch on controller bed controller disconnects simultaneously, lathe quit work and report to the police, thereby effectively preventing that operator from coming to harm; Utilize this alarm unit, can realize the transmission of warning message overlength distance, the equal transmitting in region that GPRS network covers, blind area is few, the optional global general-use of three frequency ranges; Communications service based on GPRS network, without application frequency, without building base station.In addition, the utility model can also detect the situation of self, as breaks down, and also can make production equipment quit work and protect personal safety, safety device can effectively protect operator to avoid the injury of machine.

Accompanying drawing explanation

Fig. 1 is functional block diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of lathe safety guard with remote alarms, comprise photoelectric detector, master controller, buffer, self-checking circuit and machine tool controller, described photoelectric detector is connected with master controller with buffer, buffer is all connected with master controller with self-checking circuit, master controller is connected with machine tool controller, on machine tool controller, be connected with an emergency stop switch, on described master controller, connect an alarm unit, described alarm unit is by detector, controller and communication module form, detector, detector is connected by wire with controller, for alarm part, on the controller of alarm part, pass through wire connecting communication module.

During use, master controller can first detect the duty of self automatically by self-checking circuit, if device itself breaks down, this device can be certainly about to lathe and be quit work, and reports to the police, until device repairs, and the normal use of assurance equipment; In use procedure, when if operator's hand stretches into deathtrap, photoelectric detector and position detector are exported a control signal simultaneously, this signal is transferred in master controller, then by master controller, this information is analyzed, compared, after true genus dangerous situation, emergency stop switch on controller bed controller disconnects, lathe is quit work and report to the police, utilize this alarm unit, can realize the transmission of warning message overlength distance, the equal transmitting in region that GPRS network covers, blind area is few, the optional global general-use of three frequency ranges; Communications service based on GPRS network, without application frequency, without building base station.

The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
