刷見本と比較することが行なわれている。In a sheet-fed printing press, the quality paper printed by the printing unit is
The paper is conveyed while being held in the claws of the paper ejection chain, and at the end of the conveyance, it falls onto a device composed of claws and is stacked. When performing such printing work, the operator must check the printing condition of the printed material that is being ejected because it cannot be connected, and must visually check the ejected paper that has fallen onto the paper ejecting section due to slipping. However, in order to perform a more complete confirmation, the printing paper (hereinafter referred to as paper) that is being discharged and falling is removed and compared with an IRD and a print sample prepared in advance.
ことに、番号印刷においては、正紙中に不正紙や刷見本

安全性において大きな問題が残されて一九。However, in recent years, as printing presses have become faster, it has become extremely difficult to remove falling or stacked papers, and even if it is possible to remove them, problems such as misalignment of normal paper are more likely to occur. However, since the operator has to put his/her hands into the equipment during operation, there remains a major problem in terms of work safety.

下、本発明の一実施例を図面に基いて詳細に説明する。The present invention was developed in view of the above points, and includes a fixed cam at the end of the paper ejection conveyance of the paper ejection chain, a switching cam in front of the fixed cam, and a normal line switching cam that opens the paper ejection mold and allows the paper ejection mold to be opened under the fixed cam. When the paper is set up, the output paper is placed on the paper stacking stand, and when the paper is removed,
By switching the switching cam, the fixed cam releases the paper discharge mold that has passed, and the paper discharge tray is placed below the paper discharge tray. By configuring the paper so that it falls on top of the paper ejection tray, paper can be ejected to another path in an orderly manner while the machine is running with the simple act of switching the switching cam (p1 manual or automatic control). To provide a paper discharging device for a nine-sheet printing press, which enables the paper to be removed, eliminates the problem of normal paper discharging due to the removal of baffle paper, and ensures work safety. Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

める。The operation of the paper ejecting device configured as above will be explained. Loosen the cook handle 29 and rotate the switching handle 28 to set the right switching cam 25 of the front and rear switching cams 25, for example, in the chain line position, and set the left switching cam 25 to the solid line position to lock the lock handle 29. Tighten. ζWhen printing starts, paper is supplied from the paper feeder 2 and sent to the printing unit 3.
The printed paper 5 is conveyed while being caught by the paper ejection wind 19 of the paper ejection chain 11 and the claw base 20, and the ζ roller 22 comes into contact with the right switching cam 25 located at the chain line position. The paper discharge claw 19 is opened and the paper is dropped and stacked on the right O paper stacking table 23 at the 5th intersection. The worker stands at the paper discharge section and when a predetermined number of sheets (1, for example, 300 to 500 sheets of paper 5 for number printing) are stacked on the paper stacking table 23 on the right side, an alarm such as a buzzer notifies the user of this. , loosen the lock handle 29 and open both switching handles 28.
After rotating the lock handles 29 in opposite directions, tighten the lock handle 29.

While the paper 5 is stacked on the left paper stack 23, the right paper 5 is taken out along with the paper stack 23 and replaced with an empty paper stack 23, and then the same operation is repeated. , without stopping the machine (the paper 5 is placed in the left and right paper stacking devices 2).
4 can be loaded alternately.

着く。In the case of stacking paper, loosen the lock handle 29 on the side where discharged paper is being loaded, rotate the switching handle 28, and switch the switching cam 25 to the solid line position. The roller 22 contacts the fixed cam 34 and opens, so that the paper 5 is released from the paper discharge wind 1g. In the case of paper guide 4T, the paper discharge wind 19 while traveling is
Due to the free end facing between the paper ejection chain 1
The paper 5, which is given an initial speed when released from the paper ejection claw 19 due to the high-speed running of step 1, is ejected into the paper ejection tray 39 along the lower surface of the paper guide 47 due to inertia, and its leading edge reaches the paper abutment 41K.
'S, stops and is loaded. Note that the position of the fixed cam 34 in the front-rear direction is adjusted in accordance with the printing speed, taking into consideration the position where the paper 5 just contacts the paper pad 41 due to its inertia after being ejected. In the ejecting operation of the paper 5 carried out in the manner shown in FIG. Since air is blown from above onto the paper surface between adjacent paper guides 47 by the air nozzle 52, the paper 5 settles down without floating up.

Since the good paper guide 4T is movable in the front and rear directions, it is possible to freely set the KM by checking the state of the paper 5 being settled. Further, since an air vent hole 40 is provided in the bottom plate of the paper receiving tray 39, air will not accumulate between the paper 5 and the bottom plate and the paper 5 will not settle properly. Then, the number of times the paper 5 is removed from the paper ejection tray 39 is several tens of times depending on the time.
It is also possible to take out sheets of paper.In this case, because the paper gathering plate 42 is movable and adjustable, the edges of the paper can be well aligned regardless of the size of the paper.

。In this embodiment, an example is shown in which the switching cam 25 is switched by operating the switching handle 28, but it may also be operated by an electric push button, and furthermore, the switching cam 25 may be operated by an electric pushbutton, and furthermore, the switching cam 25 may be operated by an electric pushbutton, and the switching cam 25 may be switched by the printing unit 3 instead of by manual operation. The switching may be performed automatically by an electric signal, or in a printing machine equipped with an inspection device, the switching may be performed automatically by a fraudulent paper detection signal issued by the inspection device, and the fraudulent paper may be ejected to the paper ejection tray 39. . Further, the paper stacking device 24 is not limited to the double pallet type, but may be one set of this type.

めて容易になる。As is clear from the above description, in the present invention, in the paper discharge device of a sheet-fed printing press, a fixed cam is provided at the paper discharge transport end of the paper discharge chain, and a switching cam is provided in front of the fixed cam. Normally, a switching cam is used to release the paper ejecting air, and the paper is ejected onto a good paper stacking table below the cam.When removing paper, a fixed cam is used to release the ejecting air that has passed through the switching cam, and the paper is ejected onto a good paper stacking table. The paper ejection tray provided at the bottom is configured to eject the paper from the upper sail, and a paper guide and an air nozzle are provided above the paper ejection tray so that the ejected paper falls on the upper side of the paper ejection tray. By simply switching the switching cam through manual operation using a pushbutton or automatic control using electric signals, you can switch between discharging paper to the paper stacking device and discharging the paper to the paper ejection tray while the machine is running. Since it is possible to remove fraudulent papers and printed copies without touching them, it is possible to eliminate the occurrence of disturbances in normal paper output due to paper removal, and to reduce the amount of paper waste. It is possible to reduce the amount of work required and eliminate the need for paper alignment, as well as improve work safety and eliminate the need for skill. First, since the paper ejection tray has a good grip on the upper paper, the paper ejection is switched in an orderly manner, and no accidents occur. Furthermore, compared to the case where a dedicated loading device is provided for paper removal IS, the structure is simpler and the space occupied can be reduced.
By automating the switching of the switching cam, work management becomes extremely easy.
