いる。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 4 schematically show the configuration of a printed matter monitoring apparatus according to an embodiment of the present invention. Reference numeral 1 denotes a web as a printed matter, an image is formed in a printing section (not shown), and a transport roller 2 It is conveyed and guided by a plurality of rollers such as , etc., and sent to a folding machine section (not shown). Stains on the printed surface occur due to accidents such as flying ink, water dripping, oil dripping, etc., so it must be constantly monitored. Therefore, a detection sensor 4 for detecting dirt on the printing surface 3 of the web is provided in the middle of this conveyance path. The detection sensor 4 is a linear member extending in a direction perpendicular to the flow direction of the print surface, and scans the print surface 3 for each linear detection area of a predetermined width to sequentially monitor dirt. This detection sensor 4 has a large number of light receiving elements 5 that correspond one to one to a unit pixel area. Each unit pixel area is one area obtained by dividing the linear detection area of the printing surface 3 into a large number of detection areas. Reflected light from the unit pixel area is transmitted to a large number of light receiving elements 5 through optical fibers 6. A light source 7 is provided to illuminate the line-shaped inspection area of the printing surface 3. A photocurrent is generated by the light receiving element 5 according to the intensity of the light reflected from the printing surface, and this is converted into a signal corresponding to the reflected light by converting the current to voltage using an operational amplifier or logarithmically converting it using a log amplifier. Normal/abnormality determination processing is performed. A portion where the illumination light of the light source 7 exits from the detection sensor 4 constitutes an inspection surface 4a, and a transparent plate 8 is provided on the inspection surface 4a.
Prevents dust and paper powder from adhering to the surface. During printing, the detection sensor 4 is located at an inspection position T near the printing surface 3, as shown in FIG. 2, and monitors dirt. At this time, the transparent plate 8 prevents paper powder, dust, etc. from entering the detection sensor 4.

(not shown)
, 16. The arm 13 is connected via a pin 18 to an air cylinder 17 attached to a frame (not shown) for rotating the arm 13. When air is introduced into the air cylinder 17 in the direction in which the rod 19 extends, the arm 13 rotates clockwise around the rotation center axis 15 in accordance with the extension of the rod 19, which causes the detachable pin 9 to rotate clockwise. rotation, detection sensor 4, detachable pin 10
, the arm 14 rotates clockwise. This clockwise rotation is restricted by fully extending the rod 19 of the air cylinder 17 or by providing a stopper. Thereby, the detection sensor 4 will move to the inspection release position R. Conversely, when air is introduced in the direction in which the rod 19 of the air cylinder 17 contracts, the arm 13 rotates counterclockwise in accordance with the contraction of the rod 19, and the attachment/detachment pin 9, detection sensor 4, attachment/detachment pin 10, The arm 14 rotates counterclockwise. This counterclockwise rotation is restricted by cutting the rod 19 of the air cylinder 17 or by providing a stopper. Here, air cylinder 17, rod 19, pin 18, rotation center shafts 15, 16, arms 13, 14
, the attachment/detachment pins 9 and 10, and the brackets 11 and 12 constitute a moving means A. As a result, the detection sensor 4 moves to the inspection position T.

Here, the air nozzle 20 and the nozzle 21 constitute a cleaning means B. When the detection sensor 4 is in the inspection release position R, if air is sent to the air nozzle 20, the air will blow against the surface of the transparent plate 8 of the detection sensor 4 through the plurality of nozzles 21, removing dust attached to this surface.・Can remove paper dust, etc.

監視を行う必要がない。By the way, in a rotary offset printing machine, it takes about 30 minutes to print one roll of paper. The transition from one web to the next is generally accomplished by an automatic paper cutting device without stopping printing. Dozens of printed copies before and after this paper splicing area cannot be used as a product due to printing misregistration, etc., and are therefore discarded. Therefore, while this defective portion passes through the detection sensor 4, there is no need to monitor the print surface for dirt.

Accordingly, the time required for the paper splicing portion to pass the detection sensor 4 is determined by the delay device 24 as a control means, and a detection sensor release signal 25 is generated, thereby causing the solenoid valve 26
to supply air from the air source 27 to the air cylinder 17.
is applied in the direction in which the rod 19 extends, and the detection sensor 4 is moved to the inspection release position R. Movement end time delay device 24
After the air blowing signal 28 is generated, the solenoid valve 29 is operated, and air from the air source 27 is supplied to the air nozzle 20 for a certain period of time, the air blowing signal 28 is cut off by the delay device 24. Next, the delay device 24 generates a detection sensor arrival signal 30, which is applied in a direction to retract the rod 19 of the air cylinder 17, thereby moving the detection sensor 4 to the inspection position T.

除去を行うことができる。In this way, the inspection surface 4 of the detection sensor is detected while the defective portions before and after the paper splicing portion of the printed surface pass the detection sensor 4.
Since it is used to remove dirt such as dust and paper powder adhering to the surface a, the dust and paper powder can be removed without interrupting the monitoring work of the printing surface 3.

By blowing air to 4B, the inspection surface 4b of the detection sensor can be protected from dust, paper powder, etc. without bothering the operator.

By doing so, dust, paper powder, etc. attached to the transparent plate 8 of the detection sensor 4 can be removed while the detection sensor 4 is in the inspection release position R.

清掃が行われる。In addition, when carrying out paper threading work, the operator gives a manual release signal 31 to the delay device 24, and the delay device 24 gives a sensor part release signal 25 and an air blowing signal 28. The operator manually inputs the arrival signal 32.
By applying this to the delay device 24, the delay device 24 first gives the air blowing signal 28 and then gives the sensor arrival signal 30, so that the detection sensor 4 is moved and the transparent plate 8 is cleaned.
