After the incorrect sheet passes, the push button is pressed to contact the actuator 39 so that the felt 40 is laid down and a counting operation is restarted. Further, a mark can be put at every fixed number sheets in the same manner for distribution.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching an indicator indicating that the paper is a specific paper such as a fraudulent paper or a predetermined number of sheets to the edge of paper discharged after printing in a sheet-fed printing machine. In printing work using a sheet-fed printing machine, incorrect paper may be generated due to a nail that fails to grip or a malfunctioning paper feed tube, and this paper is mixed in with the original paper and is ejected, resulting in an incorrect number of printed sheets. If paper is included in the count, it is not only impossible to know the exact number of printed sheets of genuine paper, but it is also extremely difficult to extract fraudulent paper after it has been stacked. Furthermore, when shipping printed matter in sections of a predetermined number, it is extremely inefficient if the sheets are piled up in a bar without being counted midway through, as the counting must be done again after the sheets have been loaded.

Conventionally, when such fraudulent paper is generated or the number of printed sheets reaches a predetermined number, the operator visually checks this in the paper output section and inserts a piece of υ paper with the printed paper folded into this area. After the paper has been loaded, the unauthorized paper is removed and the paper is sorted according to the number of sheets to be loaded. In addition, in the case of fraudulent paper, count the number and subtract it from the value on the counter to determine the number of genuine papers υ, or in some cases, stop counting every time a fraudulent paper occurs. was also carried out.

However, it is extremely dangerous to insert a piece of paper between sheets of paper that is being ejected at high speed, and the purpose may not be achieved if a piece of paper falls out due to failure to insert it or enters the loaded paper. It was extremely primitive and inefficient work.

The present invention has been made in view of the above points, and it is possible to improve the label attaching work by providing an ink-impregnated body that advances and retreats from the edge of the discharged paper and attaches the label to the specific paper being discharged. To provide a device for attaching a label to the edge of paper in a sheet-fed printing machine, which is designed to improve safety and facilitate the removal of specific paper from a stack of paper. Embodiments of the present invention will be described in detail below with reference to the drawings.

A cross-sectional view of the horizontal adjustment device, the third time, also a vertical cross-sectional view, Fig. 4 is a view taken from A in Fig. 3, Fig. 5 is a front view of the vicinity of the ink-impregnated body when not in operation, Fig. 6 FIG. 2 is a perspective view of a cover for an ink-impregnated container.

In the figure, the paper ejection device includes a pair of left and right paper ejection frames 1 connected to the frame of the printing unit, and a sprocket 3 on a sprocket shaft 2 mounted on the front end of the horizontal part, and a sprocket of the printing unit. A pair of left and right paper ejection chains 5 are stretched between the sprocket 4 and the intermediate sprocket 4.

A plurality of gripping claw devices 6 (hereinafter referred to as molds 6) having claws and claw stands are arranged on each of the plurality of claw rods supported at regular intervals between the left and right paper ejection chains 5. An opening/closing cam that opens and closes the pawl 6 is provided near the sprocket 3. Reference numeral T denotes a paper stacking table which can be raised and lowered to load papers 8, and is disposed below the horizontally running force of the paper discharge chain 5. The printed paper 8 is then conveyed while being caught in the claw 6 of the paper ejection chain 5 running in the direction shown by arrow A. When the claw 6 is opened by a cam mechanism in front of the sprocket 3, it is released from the grip. The paper stacking platform 7 is configured to automatically descend in accordance with the amount of paper loaded.

The paper discharge device 9 configured in this manner is subject to falling paper.

A paper pad 10 that brings the leading edge of the stacked paper 8 into contact with each other to align its vertical edges; a suction wheel 11 that sucks the bottom of the paper to correct the disordered falling posture of the paper 8 due to running inertia; ,
A lateral alignment device 12 is provided to align the stacked papers 8 in the width direction. Of these, the lateral shifting device 12 will be explained in detail based on FIGS. 2 and 3. A sleeve 14 is slidably supported on bushings 13 fitted to the left and right paper discharge frames 1. Between the washer 16, which is fitted onto the inner end of the sleeve 14 and prevented from coming off by a snap ring 15, and the washer 1T inside the frame 1, there is a
A compression coil spring 1B that biases the sleeve 14 toward the inside of the frame 1 is interposed on the sleeve 14. A lever 20 whose rotation is regulated by engaging a U-shaped groove with a pin 19 implanted in the frame 1 is fitted into the outer end of the sleeve 14, and the lever 20 is equipped with an adjustment knob. The lever 20 and the sleeve 14 are integrally fixed by inserting a screw.

On the other hand, a cam lever shaft 21 is rotatably supported on the paper ejection frame 1 in parallel with the sleeve 14, and this cam lever shaft 21 has cam levers 22 fixed to both sides of the frame 1. The lever 23 restricts movement in the axial direction. At the free end of the cam lever 22,
A cam 25 that presses the roller 24 attached to the lever 20 by the elastic force of the compression coil spring 18 is integrally formed, and the cam that comes into contact with the roller 26 at the free end of the roller-equipped lever 23 is not shown. The lever 23 with P rollers and the cam lever 22 are swung by the driving device, and the sleeve 14 is reciprocated in the width direction of the paper 8 by the action of the cam 25.

The sleeve 14 that reciprocates in this manner has a T-shaped holder that is integrally formed with a pipe-shaped support shaft 27 and a strip-shaped support plate 28 that is welded to the tip of the support shaft and extends in the vertical direction of the paper 8. 29 support shafts 2T are slidably supported through the frame 1, and their protruding portions toward the inside of the frame 1 are supported by a bracket 30 fixed to the frame 1. The holder 29 is fixed integrally with the slim nib 14 by an adjustment screw screwed into the lever 20 and reciprocates,
It is configured to be moved in the axial direction and fixed at any position by loosening the adjustment screw. Holder 2
The support plate 28 of No. 9 has a pair of screws 311C on the support plate 30.
A pair of front and rear paper pads 32 are pivotally attached to the front and rear panels 30 so as to be rotatable. Then, by loosening the screws 31, moving the latch plate 30 in the length direction, and changing the attachment using another screw hole 33, the paper size can be changed.

With this configuration, the shifting plate 30 and paper abutting bar 32 of the horizontal shifting device 12 fall onto the plate 34 on the paper stacking table 7, and are prevented from coming into contact with or separating from the edges of the stacked papers 8. The paper 8 is reciprocated to align the edges of the paper 8, and this lateral alignment device 12 is equipped with a device for attaching a label to the edge of the paper. That is, at the end of the support plate 28 located on the paper feeding side,
A solenoid support plate 34, which is formed into a U-shape when viewed from the rear as shown in FIG. 4, is overlaid on the support plate 28 and integrally formed therewith, and a connected solenoid 36 is screwed thereto. Further, above the solenoid 36, as shown in a perspective view in FIG. 6, a cover 37 formed in the shape of an L-shaped box engages within the bifurcated portion of the solenoid support plate 34, and its lower end portion can freely rotate. The working end of the actuator 390 of the solenoid 36 is pivotally attached to the elongated hole plate 3B protruding from the back of the cover 370. By doing this, when the solenoid 36 is activated, the actuator 39 is activated. Upon extension, the cover 37 rotates from the lying position shown in FIG. 5 to the upright position shown in FIG. A felt 40 as an ink-impregnated body is housed in the cover 3T, and an ink bottle 4 supported on the frame 1 via a frikerato 41 is housed in the felt 40.
2, it is impregnated with ink supplied by a vibrator 43 that passes through the support shaft 27 and is guided to the cover 37. ζ By doing so, when the paper 8 being held and conveyed by the claws 6 passes through the felt 40 while the felt 40 is upright and its edge comes into contact with the felt 40, ink will adhere to the edge of the paper 8. . 4
Reference numeral 4 designates an ink outlet bored at the bottom of the cover 37 to discharge excess ink.

The pushbutton that activates the solenoid 36 is also connected to a counter that counts the number of printed sheets.
Counting by the counter is stopped by operating B in the upright direction of the cover 31, and by lowering the cover 3T again, the counter continues counting before stopping.

The operation of the paper ejecting device configured as above will be explained. After printing, the nine sheets of paper 8 are conveyed by the claws 6 of the paper discharge chain 5, and are released from the grip and fall when the claws 6 are opened by a cam mechanism in front of the sprocket 3.

At this time, the paper 8, which has running inertia, is braked by being sucked by the suction wheel 11, its front end is aligned with the paper pad 10, and it falls and is stacked on the scrap board 45.

A side shifting device 12 is provided on the side of the paper 80 to be stacked, and its shifting plate 30 and paper abutment par 32 move back and forth so as to touch the edge of the paper 8 and move away from the edge of the paper 8. Since the paper 8 is vibrated, the papers 8 are correctly aligned and stacked. The counter counts the number of printed sheets.

The operator stands next to the paper ejecting device 9 and visually observes the paper 8 being conveyed, and if he or she finds a fraudulent paper, he or she presses a push button. Then, at the same time as the counter stops counting, the solenoid 36 is activated and the actuator 3g is extended, causing the felt 40 that had been lying down to stand up as shown in FIG. The impregnated ink adheres to the edge of the fraudulent paper that is conveyed while touching the reciprocating felt 40. When removing fraudulent paper after loading, if you look at the loaded paper from the side, you can easily see the fraudulent paper with ink marks attached to the edges.
This can be easily removed. After the fraudulent paper has passed, the actuator 39 of the solenoid 36 is contracted by pressing the button, the felt 40 is collapsed, and the counting of the argument device is restarted.

The above explains the attachment of labels to fraudulent paper.
The specific paper is not limited to fraudulent paper, but can also be similarly applied to label paper when it is desired to attach a label to each predetermined number of sheets for sorting purposes. In this case, when the counter counts a predetermined number, the push button may be pressed to activate the solenoid 40t. In addition, in the case of nickel, the counter is used as a preset counter, and it is electrically connected to the solenoid for label attachment, so that the label can be attached to one or more sheets automatically every predetermined number of sheets. This eliminates the need for operators to concentrate on attaching labels to fraudulent paper. Furthermore, if a fraudulent paper detection sensor is provided to detect fraudulent paper without visual inspection, no workers are required. Although the present embodiment shows an example in which the label adhering device is attached to the side shifting device, it may be provided anywhere within the paper discharge path.

However, if it is installed in the side shifting device, this device will always move back and forth toward the edge of the paper, so the label will be attached reliably, and if the paper size is changed, the side shifting device will always move back and forth. Because it is adjusted according to.

The label adhering device automatically follows the paper size and is effective.

As is clear from the above explanation, according to the present invention, in a sheet-fed printing press, an ink-impregnated body is provided which advances and retreats from the edge of the discharged paper and attaches a mark to a specific paper being discharged. In addition, when incorrect paper is generated or when you want to separate the ejected sheets by a predetermined number of sheets, it is possible to eliminate the dangerous work of sandwiching the label paper between the ejected sheets at this point, improving work safety. At the same time, the label paper can be reliably and easily confirmed after loading without the risk of inability to identify it due to Iji#1 & paper falling off, so there is no need to re-sort fraudulent paper, and it is possible to load each predetermined number of sheets. This makes the work easier and the work efficiency is significantly improved.Furthermore, since the mark is located within the cutting margin at the edge of the printed material, the printing unit can clean and effective.
