Technical field
The utility model relates to a kind of control device, refers in particular to a kind of automaton that is used to monitor the board and frame machine deflection.
Background technology
Along with the continuous development of plate compression machine technology, occurred that filter area is big, the type of complete machine length overlength.The side plate of super long type plate and frame filter press may cause distortion because of the out-of-balance force that a variety of causes forms in the course of the work, and the distortion serious situation can threaten to equipment itself and operating personnel.All do not have to monitor the device of the side plate deflection of plate and frame filter press on the at present domestic plate and frame filter press, become the blank spot in the control of filter press automatic operating.
In view of this, the utility model provides a kind of automaton that is used to monitor sheet frame pusher side plate deflection, and it can monitor the deflection of sheet frame pusher side plate automatically, avoids damage equipment itself and threat operating personnel's personal safety.
The utility model content
The utility model provides a kind of automaton that is used to monitor sheet frame pusher side plate deflection, and it can monitor the deflection of sheet frame pusher side plate automatically.
The utility model is achieved in that
A kind of control device that is used to monitor sheet frame pusher side plate deflection, it is installed on the board and frame machine side plate, this control device includes: the induction bar, near switch and control system; Wherein, this induction bar is installed on this board and frame machine side plate, the induction object when its deflection as this board and frame machine side plate does not exceed maximum fair deflection; Should respond to the adjacent setting of bar near switch and this, when this induction bar was in or exceed this near the induction range of switch, this was near switch open or close, and exported the corresponding signal of telecommunication; This control system with should be connected near switch, it is used to receive this near the signal of telecommunication of switch and produce alarm signal.
Preferably, the length of this induction bar is L, and the permission deflection of the bilateral of this board and frame machine side plate is L/2 and is somebody's turn to do detecting apart from sum near switch.
In order to make this control device can be applicable to the board and frame machine side plate of different length, according to the length setting monitoring range of board and frame machine side plate and set the length of this induction bar.
Preferably, this control device also comprises slide rail, and this can be somebody's turn to do near the distance between switch and this induction bar in the Position Control on this slide rail near switch by controlling this near being located on the slide rail that switch slides.
In order to monitor the deflection of this board and frame machine side plate more accurately, preferably this control device is installed on the deflection maximum of this board and frame machine side plate, reach accurate monitoring to this side plate deflection.
Preferably, this control system is preferably the PLC system.
Technique effect of the present utility model:
The utility model is used to monitor the control device of sheet frame pusher side plate deflection can monitor in real time to the deflection of this board and frame machine side plate, avoids damage equipment itself, and threatens operating personnel's personal safety.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figure 1 to Figure 3, the utility model is used to monitor the control device of sheet frame pusher side plate deflection, and it is installed on this board and frame machine side plate 1, and this control device includes: the induction bar 2, near switch 3, slide rail 5 and PLC system 6.Wherein, this induction bar 2 is installed on this board and frame machine side plate 10, and arranged in a crossed manner with this board and frame machine side plate 10, the induction object when its deflection as this board and frame machine side plate 1 does not exceed maximum permission deflection; Should be located on this slide rail 5 near switch 3, with these induction bar 2 adjacent settings, when this induction bar 2 was in or exceed this near the induction range of switch 3, this was near the unlatching of switch 3 or close, and exported the corresponding signal of telecommunication; This PLC system 6 by holding wire 4 with should be connected near switch 3, be used to receive this near the signal of telecommunication of switch 3 generations and produce alarm signal.
In order to make this control device can be applicable to the board and frame machine side plate of different length, according to the length setting monitoring range of board and frame machine side plate and set the length of this induction bar.
Preferably, the length of this induction bar 2 is L, the permission variable of the bilateral of this board and frame machine side plate 1 is L/2 and is somebody's turn to do detecting apart from sum near switch, because of the maximum of the board and frame machine side plate 1 of different length allows the deflection difference, so can change this near the distance between switch 3 and this induction bar 2 near switch 3 in the position on this slide rail 5 by changing this.
In order to control the deflection of this board and frame machine side plate more accurately, preferably this control device is installed on the deflection maximum of board and frame machine side plate 1.
Preferably, be eddy current type near switch, capacitive approach switch, proximity Hall switch, photo-electric near switch, pyroelectricity formula near in the switch any near switch in the utility model.
This control device is when work, owing to the distortion of board and frame machine side plate 1 produces displacement, if displacement greater than the scope of setting, produces a signal of telecommunication near switch 3, the working procedure of board and frame machine will be reported to the police and interrupt to this PLC control system 6 after receiving this signal of telecommunication, disappear up to this signal of telecommunication.
As Fig. 4 and shown in Figure 5, it has illustrated the embodiment of different length board and frame machine side plate.When board and frame machine side plate length is 16705mm, can allow the variable and the length that distance is determined this induction bar that detects near switch according to the maximum of this board and frame machine side plate, preferably the length L of this induction bar 2 is 300mm; When board and frame machine side plate length is 19705mm, can allow the variable and the length that distance is determined this induction bar that detects near switch according to the maximum of this board and frame machine side plate, the length of preferably responding to bar is 500mm.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
