Technical field
The present invention relates to a kind of control system of collection storehouse of intaglio printing press, particularly a kind of three-bin control system of gravure press.
Background technology
Originally had three collection storehouses on the super recessed machine, 1# and 2# storehouse are the collection that flat collection storehouse is used for normal product, and 3# collection storehouse is inclined collection storehouse, are used for sampling, therefore can not deposit too much product.Three photoelectric sensors that are used for 1# collection storehouse counting, 2# collection storehouse counting, 3# collection storehouse counting are installed in these three collection storehouses respectively, and they are directly inputted among the control device PLC of super intaglio printing press as the input signal that detects.These photoelectric sensors mainly contain three functions: 1, the product that falls into corresponding collection storehouse is counted.2, detection judges whether defeated paper portion transmission product falls into regulation collection storehouse correct, falls into collection storehouse incorrect (as: should fall into 1# collection storehouse, but drop on 2# collection storehouse or 3# collection storehouse) as fruit product, and just emergency shutdown is also reported to the police immediately.3, whether testing product transmits in the product process at paper feed mechanism and loses, and falls into 1# collection storehouse as fruit product at first when transmitting, but does not fall into, with regard to hard stop.
Because after on the super recessed machine on-line detecting system device being installed, product can separate the sheep from the goats, run into the problem that detected bad product does not have position in storehouse to deposit, the inclined design in originally super recessed sampling storehouse (3# collection storehouse), can not deposit too much product again, this defective makes the function of on-line measuring device really to bring into play, can only be with the usefulness of checkout gear as continuous disregard message police.At this defective, mechanically the 3# storehouse of super recessed machine is changed into flat collection storehouse by inclined and be used to collect the bad product that stacking testing agency is distinguished, and liftable, mechanically also increase by one group and held tooth row in the month.Hold tooth row in the month owing to increased this group, this makes control system paper feed mechanism can't be transmitted product and accurately falls in the collection storehouse of regulation that the part control action is not right, and the control fault appears in machine, mainly comprises:
1. the collection cam action in collection storehouse is not right, makes paper not arrive and specifies position in storehouse;
2. as long as machine one combined pressure, the product that defeated paper subordinate comes does not just suddenly stop to the collection storehouse, makes the machine can't operate as normal.
3. counting is inaccurate, and it is not right to sample.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of three-bin control system of gravure press, with the abnormal problem of intaglio printing press control action after the solution 3# storehouse transformation.
Goal of the invention of the present invention is achieved by the following technical solution:
A kind of three-bin control system of gravure press, the PLC that comprises original intaglio printing press system, the new small PLC that adds in the intaglio printing press system is under the 1# collection storehouse cam among original super recessed machine controller PLC, on the cam of 1# collection storehouse, 1# collection storehouse is synchronous, under the cam of 2# collection storehouse, on the cam of 2# collection storehouse, 2# collection storehouse is synchronous, 3# collection storehouse these seven signals of counting photoelectric sensor are linked in the small PLC controller of new interpolation, utilize these 7 signals that three collection storehouse cams are carried out corresponding control.Reach original two control functions that will realize simultaneously, satisfy and produce needs.
The small PLC of described new interpolation adopts the C200H PLC of Omron.
Write the control program of new control system by Omron CX-P programming software, make cam action control normal by writing and debug new system program.Just, because original system can't update routine, so add a little new system.Original system is controlled the upper and lower output signal of cam directly do not control collection cam actuator, but the input signal of the new system of conduct, after upward (or down) signal of cam is received by new system, output again behind time-delay one circle, control cam actuator, make product drop on the appointment position in storehouse, solved 3# collection storehouse and tiltedly leveled off the problem that the back produces.
This method is to add a small PLC in original system, can adopt the C200H PLC of Omron, the paper feed portion of original control system and the part input of collection portion are received in the new small PLC with output signal, make the newly-built PLC system and the PLC of original control system set up point-to-point communication, read the signal that needs.With stylish design detection and safeguard protection circuit; increase new sensor, reset some sensing stations, make cam action control normal by writing and debug new system program again; and the anxious fault of stopping disappears all control problems that occur after solution is tiltedly leveled off fully.
Description of drawings
Fig. 1 does not transform preceding control mode figure for the 3# storehouse;
Fig. 2 is control mode figure of the present invention after the transformation of 3# storehouse.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the present invention and how to realize.
Embodiment
As shown in Figure 1, for prior art is that preceding control mode figure is not transformed in the 3# storehouse, the input signal of three photoelectric sensors of 1# collection storehouse counting, 2# collection storehouse counting, 3# collection storehouse counting is directly sent in the control device of intaglio printing press PLC.
As shown in Figure 2, the input signal of the photoelectric sensor of 3# collection storehouse counting is linked in OMRON (Omron) the C200H PLC control input unit, simultaneously with under the 1# collection storehouse cam among original intaglio printing press controller PLC, on the cam of 1# collection storehouse, 1# collection storehouse synchronously, under the cam of 2# collection storehouse, on the cam of 2# collection storehouse, 2# collection storehouse synchronously these 6 signals small PLC controller of being linked into new interpolation be among OMRON (Omron) C200HPLC.
After the 3# storehouse changed into and closing a position, this storehouse can be risen and fall by motor-driven, had increased upper and lower limit position sensor, overcurrent protection switch.When rising on the 3# storehouse or dropping to certain position, the limit position sensor action, can not continue to rise or descend in the 3# storehouse, guarantee device security; When the load of 3# storehouse was heavily arrived to a certain degree, motor safety was guaranteed in the overcurrent protection switch action.
The photoelectric sensor of former three collection storehouses counting is in the position in corresponding collection storehouse, from the product that paper feed portion sends, machine changes 12 and encloses top, 1# storehouse, and 13 enclose top, 2# storehouse, 14 enclose top, 3# storehouse, and the photoelectric sensor of corresponding collection storehouse counting receives that paper is to signal.With the 2# storehouse is the example explanation, the product that paper feed portion sends, after machine changes 13 circles, if the photoelectric sensor of 2# collection storehouse counting has been received the paper signal, show that product has arrived the 2# storehouse, under the control collection cam, this product is fallen the 2# storehouse, if the photoelectric sensor of 2# collection storehouse counting is not received the paper signal, illustrate that product has fallen halfway, machine shuts down.The 3# storehouse by oblique storehouse change into close a position after, mechanically increased by one group and held tooth row in the month, the product of sending from paper feed portion to the 1# storehouse, variation taken place in the number of turns of 2# storehouse and 3# bin location, becomes 13 circles, 14 circles and 15 circles, promptly many circles.Still be example with the 2# storehouse, after the product that paper feed portion sends, machine changeed 13 circles, the photoelectric sensor of 2# collection storehouse counting had not been received product signal (as long as after in fact machine forwarded 14 circles to, photoelectric sensor just can have been received the paper signal), and machine shuts down.In order to guarantee that machine changes the photoelectric sensor place that 13 circle back products arrive 2# collection storehouse counting, must be with this sensor reach one circle position.Behind the preceding displacement sensor, the number of turns that the product of paper feed portion arrives the 2# storehouse is right, has produced product again and has not dropped on appointment position in storehouse problem, because original program is control like this, in case sensor has been received product (or product-free) signal, the collection cam is in a circle time (or on).Behind the preceding displacement sensor, after the collection cam becomes a circle, under two circles are interior (or on), cause product can not accurately drop on the appointment position in storehouse.Because original system can't update routine, so add a little new system.Original system is controlled the upper and lower output signal of cam directly do not control collection cam actuator, but the input signal of the new system of conduct, after upward (or down) signal of cam is received by new system, output again behind time-delay one circle, control cam actuator, make product drop on the appointment position in storehouse, solved 3# collection storehouse and tiltedly leveled off the problem that the back produces.
