The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model provides a kind of lathe, comprises automatic door, also comprises: detect whether there is the checkout gear that hinders the obstruction that described automatic door closes when described automatic door is closed; Receive the detection signal that described checkout gear sends and control the control system that described automatic door is opened, described control system is connected with described checkout gear.
On existing machine tool basic, the utility model has installed checkout gear additional on automatic door or lathe housing, and whether checkout gear hinders the obstruction that automatic door closes and exist for detection of having, and the signal of checkout gear passes to control system by cable and processes.In existing design, the action of automatic door is to adopt internal processes as the control source.And the control signal of the automatic door that adopts in the utility model is the signal that checkout gear detects.So just can be when checkout gear detect two fans and obstruction is arranged between automatic doors, control system is processed accordingly and is carried out, and avoids occuring security incident, improves safety.
Automatic door take lathe describes as two fans as example.
Particularly, checkout gear is arranged on the housing that two fans close the side of the automatic door close or lathe, and when checkout gear was arranged on the side of the automatic door that closes two fan passes or lathe housing, the normal folding of automatic door was in described lathe shell nozzle place.The installation site of checkout gear should make the detection range of checkout gear act between two fan automatic doors, can not affect the normal open and close of automatic door.
Multiselect ground, when checkout gear is optical sensor, one of them is arranged on the photophore of optical sensor or light-receiving device two fans and closes the wherein side edge of a fan of the automatic door close, and wherein another is arranged on two fans and closes on the side edge or lathe housing of another fan of automatic door that closes for the photophore of optical sensor or light-receiving device; When checkout gear was pressure sensor, described pressure sensor was arranged on two fans and closes the wherein side edge of a fan of the automatic door close.
Particularly, control system comprises control module and driving mechanism, and control module is controlled the driving mechanism motion.Checkout gear is connected with the I/O unit communications of control module.Driving mechanism is placed in the automatic door upside.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described.
Be that optical sensor 4 describes in conjunction with the checkout gear in Fig. 2.Two fan automatic doors 3 at automatic door 3 close on the side that closes, equal altitudes has been installed photophore and light-receiving device two parts of light sensation sensing.Perhaps at the side that closes of passes of two fan automatic doors, photophore is installed, light-receiving device is installed on lathe housing 2 (otherwise also install can).Optical sensor does not hinder the normal folding of two fan automatic doors 3.The signal that optical sensor 4 receives is received the terminal row in the regulator cubicle of lathe by signal cable, communicate with the I/O unit of control module in control system.Driving mechanism 1 in control system is arranged on the top of automatic door 3.Cable is by the connection of connecting up of optical sensor 4 tops.Fig. 3 is the outside drawing of above-mentioned optical sensor 4.
Introduce in detail optical sensor as installation drawing and the control principle drawing of checkout gear in conjunction with Fig. 4 and Fig. 5.In Fig. 4, the signal that the photophore 101 of the optical sensor of contour installation and light-receiving device 102 are accepted transmits by signal cable 103, and control cables 104 connects power supply 105 and control module 106.So just formed a control signal input circuit.Wherein power supply 104 is the DC24V power supply, and control cables connects the I/O unit of control module 106.In Fig. 5, the terminal row 202 of sensor 201 by regulator cubicle connects the I/O unit 203 of control module, and power supply 204 is the protection induced signal for circuit provides power supply X5.5.
Be that control logic of the present utility model is described in detail below in conjunction with Fig. 6.After the instruction that the action of closing the door prepares to begin was sent by the control module control of control system, the driving mechanism of the control module control control system of control system drove automatic door and carries out the automatic door-closing action.The transducing signal that obtains by checkout gear comes whether have object to hinder closing motion between two fan automatic doors of acts of determination.If object is arranged between the automatic door of two fan closing motions, control module finish to be carried out and to be closed the door action and to carry out the action of opening the door, until automatic door is got back to the action position before of closing the door.If checkout gear is not sensed object between the automatic door of two fan closing motions, the driving mechanism of the control module of control system control control system continues to drive automatic door and carries out the automatic door-closing action, until automatic door is closed fully.
Multiselect ground is that pressure sensor describes in conjunction with checkout gear.Pressure sensor only has parts, gets final product so close at automatic door a side edge setting pressure sensor that closes.Make automatic door at closing time, two fan doors clip to object, and pressure sensor can produce the corresponding signal of telecommunication, thereby communicate with the I/O unit of control module, control driving mechanism and move.The installation prerequisite of pressure sensor is not affect the normal folding of automatic door.Other embodiment is consistent with optical sensor, repeats no more.
The automatic door of lathe of the present utility model is that example briefly explains when being a fan.When checkout gear was optical sensor, the photophore of optical sensor or light-receiving device were arranged on the side edge of closing the automatic door that closes, and optical sensor another part is arranged on the lathe housing; When checkout gear was pressure sensor, described pressure sensor was arranged on a fan and closes the side edge of the automatic door close or be arranged on the involutory lathe housing parts of automatic door and get final product.Consistent when checkout gear is fanned door with the effect and two of connected mode, control method and the reality of control system, do not repeat them here.
Above-described is preferred embodiment of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not breaking away under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
