Detailed description of the invention
As shown in Figure 1, a kind of defeated paper detects safeties, this device comprises left side fixed support 3, right side fixed support 7, lateral paper guide 28, lateral paper guide fixed bar 10, rolling bearing, lever block 32, pressure adjustment screw, back-moving spring and electric switch, the assembly method of single unit system as shown in Figure 1, safeties are assemblied on the left side main support 1 and right side main support 2 of the defeated cardboard in defeated paper unit, the extension that has of described left side fixed support plate 3 is stretched out in one end of described lateral paper guide fixed bar 10, on described extension, be fixedly connected with described lever block 32, the lower end of described lever block 32 is provided with described discharge cock assembly, be located at the just switch gap adjusting part moving up and down that arranges to described discharge cock assembly of uper side surface of described lever block 32, when paper foreign, described switch gap adjusting part is conflicted at the uper side surface of described lever block 32, micro-pressure gapless between the lower surface of described lever block 32 and the switch contact of discharge cock assembly is coordinated, the top of described lever block 32 is also provided with described back-moving spring 27, as shown in Figure 2, described lateral paper guide 28 side adjacent with the defeated cardboard in defeated paper unit has inclined ramp, in the time that paper surface has foreign matter, lateral paper guide 28 will drive lateral paper guide fixed bar 10 to rotate, lateral paper guide fixed bar 10 drives lever block 32 to rotate, lever block 32 separates with switch contact, equipment is under electrical equipment control, out of service, after the paper that contains foreign matter is taken out, under the effect of back-moving spring 27, switch contact and lever block 32 recover rapidly gapless, micro-pressure coordinates, electrical equipment control is recovered normal condition.
Described discharge cock assembly comprises switch 22, switch enclosure 23 and switch mounting bracket 18, described switch 22 is arranged in switch enclosure 23, switch enclosure 23 is fixed on switch mounting bracket 18 by screw 21, and described switch mounting bracket 18 is fixed on the sidepiece A surface of described left side fixed support 3 by screw 19 and pad 20.
Also comprise safeties positioning supporting rod 13, the two ends of described safeties positioning supporting rod 13 are respectively by screw 5 and screw 9 locking positionings.
Lateral paper guide 28 is fixed on lateral paper guide fixed bar 10 by bolt-locking, its specific requirement is parallel with the defeated paper-board planar in defeated paper unit, spacing can regulated according to the thickness requirement difference of printed matter paper, lateral paper guide 28 is set with the distance of the defeated cardboard face of defeated paper unit, because paper has certain bending, out-of-flatness, unavoidably lateral paper guide 28 is produced to impulsive force, easily cause paper machine in the situation that foreign is carried secretly out of service, make troubles to practical operation, want to detect the existence of foreign matter, prevent the generation of equipment breakdown, on the printed matter paper sheet thickness that meets technological requirement, increase 0.3-0.5mm, so just can guarantee that machine can normally move.Lateral paper guide 28 is one of core work point of safeties with the reasonable setting of the defeated cardboard face entirety spacing of defeated paper unit.
Uninterrupted defeated paper is the operation that moves in circles realizing under pull of vacuum and bristle brush wheel acting in conjunction by the defeated paper tape above defeated cardboard, because the existence of defeated paper tape has caused whole defeated cardboard entirety not on a horizontal plane, and defeated paper detection safeties need a smooth working face on a horizontal plane, we adopt on defeated cardboard defeated paper tape both sides and just to the stainless sheet steel of bar shaped is installed below safeties lateral paper guide 28, consistent with defeated tape thickness, width is consistent with lateral paper guide 28.Stainless sheet steel lures paper interface to need certain slope, the trouble-free operation of guarantee paper like this.Transform by above-mentioned local horizontal, make to have formed the integral planar of certain width below safeties, ensure to detect effect and do not affect defeated paper tape normally to move.
Lateral paper guide 28 and lateral paper guide fixed bar 10 form after one by bolt-locking, be arranged between left side fixed support plate 3 and right side fixed support plate 7, there is rolling bearing at two ends, can realize free rotation, lateral paper guide fixed bar 10 one end are connected with lever block 32, pass through screw lock, on lever block 32, be equipped with pressure adjustment screw 14 and back-moving spring 27, the selection of back-moving spring 27 will ensure 2 points: 1. elastic force is moderate, after ensureing foreign matter to be detected, lever block 32 is subjected to displacement, with the instantaneous disconnection of switch contact, otherwise, cannot pass through safeties although carry the paper of foreign matter secretly, but can not promptly and accurately send signal out of service, the still continual work of defeated paper unit, after resulting in blockage, can cause the damage of other device of defeated paper unit, 2. appearance and size is moderate, forms an entirety.
In the time that paper normally moves between the defeated cardboard of lateral paper guide 28 and defeated paper unit, paper will be supplied with printing element uninterruptedly, described lateral paper guide 28 side adjacent with the defeated cardboard in defeated paper unit has inclined ramp, carrying foreign matter secretly when paper enters while moving between the defeated cardboard of lateral paper guide 28 and defeated paper unit, because adding printed matter thickness, the thickness of foreign matter is greater than the spacing of setting, lateral paper guide 28 will drive lateral paper guide fixed bar 10 to rotate, lateral paper guide fixed bar 10 drives lever block 32 to rotate, the lower surface of lever block 32 separates with the switch contact of discharge cock assembly.
Fixed support plate 3 and fixed support plate 7 are arranged on the defeated cardboard support 2 of the defeated cardboard support 1 in defeated paper unit and defeated paper unit by bolt-locking, require to hold the 1000mm of tooth place in the month at a distance of printing element input, its objective is breadth width and the uninterrupted paper supply requirement continuously of considering paper, if the foreign matter that paper is carried secretly is endways time, front end has been printed the tooth of holding in the month of unit and has bitten input printing element colour cell, though detect and send signal out of service through safeties, but due to the effect of inertia, contain the paper of carrying foreign matter secretly and still have the possibility that is brought into printing element colour cell, cause the damage of device-specific anti-scratch sheath.No matter equipment, in the time of normal operation, detects the foreign matter of paper at any one position like this, and equipment all can be out of service within the scope of the running orbit of safety.
Described electrical equipment control adopts PLC to control, and Fig. 3 is the PLC signal graph of the thick detection safeties of defeated paper side, the switch contact LS-FF of described discharge cock
0in PLC signal input point X04.000D in output point access Fig. 3, when the switch contact action of discharge cock, through the programme controlled effect of internal logic circuit, outside will produce a series of action, direct effect after action is to swing tooth to inhale iron coil dead electricity, swing tooth and no longer accept initiatively paper feed operation, now, print couple loses that paper feeding → front lay detects that general character relation causes that the empty control action of front lay → fly reaches after unbalance and defeated paper yarn band stops swinging to front lay place tooth paper supply → combined pressure function and transfers tripping state → stop no longer carrying powder source → machine to depart from from printing state to losing in the situation of printing state to forme delivered ink amount → powder spraying system by version ink roller to, speed drops to running speed (for dry run state) → operating personnel and checks that reduction of speed reason → effectively stop carries the paper of foreign matter etc. secretly and enter printing element and damage anti-scratch sheath.
