[Conventional technology]

Electrophotographic copying machines that copy plain paper are equipped with a collating device (sorter). The number of things that are available is increasing. This is useful when copying meeting materials, etc. It is very convenient because it exerts its power and does not require manual collation. one Recently, as integrated plate making and printing machines have become popular, the number of pages printed from a single original has increased. Printing machines have come to be used even for relatively small quantities, and their uses have become more complex. It is approaching the camera. For this reason, there is a demand for online sorters for printing presses. It's getting stronger.

0003 However, in the case of printing machines, unlike copying machines, online sorters are connected. If you put it away, you will need a separate paper output storage tray when collating work is not required. There is a problem with it. In other words, printing presses are often used to print large numbers of copies. Therefore, a paper output tray with a large paper output capacity (500 to 1000 sheets) is required. However, the location of its installation becomes an issue.

0004 To solve this problem, as shown in Figure 6, the conventional collating device uses a dedicated non-collating device. It is generally equipped with a paper output tray 42a for sorting (Japanese Patent Laid-Open No. 60-248 (See Publication No. 566).

[0005] In the sort mode that requires collation, the printed paper follows the path shown in A. However, in non-sort mode that does not require collation, it can be resolved by taking route B. I was responding.

[0006] However, with this conventional method, the installation space for the sorter is large, and the The problem was that the protruding part of the paper output tray was a nuisance. Furthermore, nonso When printing, the paper transport path becomes longer, resulting in skew and There is a greater possibility that paper alignment will be poor, paper jams will occur on the way, and There was also the problem that it would be very troublesome to deal with the occurrence of a jam.

[0007] One way to deal with this problem is to set the sorter torrent as shown in Figure 7. There is a method to use the uppermost tray as a dedicated large-capacity paper output tray 42b for non-sorting. be. According to this method, the space can certainly be reduced and the protrusion can be reduced. Nor.

[0008] However, even with this device, the conveyance path during non-sorting is still long, and the sorter is completely It is not possible to transport thick paper because the machine is tall and the paper path is not straight. The problem is not resolved. Also, the paper conveyance guide waist part of the large capacity tray is small. Because of this, the paper cannot be ejected with sufficient firmness, and the paper ejection jack is There are also problems such as occurrence of errors and poor alignment of discharged sheets.

[0009]

[Problem that the idea aims to solve]

This invention solves the above problems in the conventional technology, and in the loading mode, the paper output tray This makes it possible to load paper securely into the tray, and also allows thick paper to pass through, and there are no protruding parts. An inexpensive online collation device with a small footprint, low height, and simple structure. The challenge is to provide.

0010

[Means to solve the problem]

In order to solve the above problem, the invention of claim 1 provides that the paper is ejected from the ejecting means. It is equipped with a paper output tray that can load a large capacity of paper, and also allows paper to be loaded into the paper output tray. Paper ejection of a printing device that has a loading mode for ejecting paper and a collation mode for collating paper. It is installed on the side end side of the direction side, is connected to the printing device, and is used in the collation mode. In the decoder, a plurality of sheets discharged from the paper discharge means are conveyed by a conveyance means. In an online collation device that sequentially outputs paper to multiple paper receiving trays, the paper guide section has an interior, a rocking means, and a control means, and the paper guide section has a first position and a second position. is supported from the main body of the collating device so as to be able to freely swing between the first position and the first position. It receives the paper discharged from the paper means and guides it to the conveying means, and at the second position, the paper is The rocking means is retracted above the path of the paper discharged from the recording and discharging means, and the rocking means The control means swings the paper guide between the first position and the second position, In the collation mode, the rocking means moves the paper guide section to the first position and the stacking In the mode, the rocking means controls the paper guide section to be in the second position. The invention according to claim 2 is characterized in that, in addition to the above, the paper guide section is At the first position, receiving the paper ejected from the paper ejecting means and conveying it to the conveying means. It is characterized by

[Effect]

According to the present invention, in the invention of claim 1, A supported paper guide is provided, which is connected to a first paper guide for receiving paper from a paper ejection means of the printing device. position and a second position retracted upward from the paper ejecting path. Therefore, in collation mode, setting the paper guide to the first position makes it easier to use. The paper can be guided to the conveying means of the collating device.

0012 On the other hand, in the loading mode, by setting the paper guide to the second position, this It does not obstruct ejection and is therefore provided in the printing device itself and located below the paper guide. Paper can be ejected and stacked onto a large-capacity paper ejection tray. The result As a result, there is no need to provide a separate paper output tray above the collating device or on the downstream side of the collating device. This prevents protrusions from forming on the collating device or increasing the height of the collating device. . In addition, in loading mode, you can use a normal large-capacity paper output tray. Enables printing and ejection of thick paper.

[0013] According to the invention of claim 2, in addition to the above, a conveyance function is added to the paper guide section. If the paper guide section slopes upward toward the downstream side or becomes longer, Even if there is, the paper will be reliably guided to the conveyance means.

【Example】

Figure 1 shows an online collation device (hereinafter referred to as "sorter") according to an embodiment of the present invention. This shows the schematic structure when combined with a stencil printing device as a printing device. . This printing device has a base paper clamp device and an ink supply device on the outer circumferential surface and inside, respectively. A cylinder with a porous structure is provided with a position (not shown) and is rotated counterclockwise in the figure. The plate cylinder 31, the press roller 32, the paper feed tray 33, the paper feed roller 34, and the paper ejection hand. A belt-type forced paper ejection device 35 as a stage, a thermal head 36 and a platen rotor. a plate-making device that performs thermal plate-making on a base paper 38 stored in a roll by a roller 37; , the base paper cutting cutter 39 and the used base paper are peeled off from the cylindrical plate cylinder 31 and stored. It has a plate discharge device 40.

[0015] The printing paper on the paper feed tray 33 is fed one by one from the top by a paper feed roller 34. An image is formed between the cylindrical plate cylinder 31 and the press roller 32, and is removed by the peeling claw 41. It is peeled off from the cylindrical plate cylinder 31 and transported by the forced paper ejection device 35 onto the paper ejection tray 42. will be loaded on. On the paper output tray 42, there are a pair of paper trays for stacking printing paper in alignment. A paper discharge side guide 43 and a paper discharge end fence 44 are provided.

[0016] In such a printing device, during normal printing in non-sort mode, which is the stacking mode, , the paper conveyance guide device 1 as a paper guide section of the sorter is indicated by a broken line C in the figure. position, and the printed paper is ejected onto the paper ejection tray 42 as described above. become.

[0017] FIG. 2 is a schematic diagram showing the structure of an online sorter according to an embodiment. The paper conveyance guide device 1 is an endless belt stretched between rollers 2 and 3. The paper is conveyed by the roller 3 from the main body 100 of the sorter. It is supported so that it can swing vertically around the axis of rotation, and its swinging action is , a worm 5 that engages with a semicircular worm wheel 6 is attached to the tip. This is done by being rotated by the rotation of the digitized motor 7. The worm 5, worm wheel 6, motor 7, etc. are examples of rocking means.

[0018] The sorter uses a cylindrical hollow cylinder 10 having an opening on its outer periphery as a conveying means; A slave cylinder 11 is provided parallel to this and below it, and a cylinder is spanned between both cylinders. A mesh-like endless belt 12 and a part of the mesh-like endless belt 12 are attached to the middle guide roller 1. 3, the lower guide roller 14, and the upper guide roller 15 to protrude outward. It has a formed part.

[0019] The main cylinder 10 is rotationally driven in the direction of arrow E by a drive device (not shown), Correspondingly, the reticulated endless belt 12 is also rotated and moved in the direction of arrow E in the figure, and the secondary series The holder 11 is rotated.

[0020] The middle guide roller 13, the lower guide roller 14, and the guide roller 15 are a unit. It is fixedly mounted on the slider 16. The slide 16 is guided in the vertical direction in the figure. It is slidable along the rail 17. Note that the middle guide roller 13 and the lower guide The drawer roller 14 and the upper guide roller 15 are rotatable around the center axis of each roller. It is set in Noh.

[0021] The slider 16 moves up and down when the screw 18 engages with the nut 19 and the screw 18 moves up and down. This is done by being rotated by the rotational drive of the lowering motor 20. Ru.

[0022] There is an air space between the main cylinder 10 and the slave cylinder 11 along the mesh endless belt 12. An air suction box 21 is provided, and by the suction action of a suction fan 22, the In step 2, generate air suction force as shown by the many small arrows to move the printing paper onto the mesh surface. The material is transported by suction onto the surface of the route.

[0023] At the tip of the protrusion of the mesh belt 12, a plurality of sheets of paper are placed vertically at regular intervals. Receiving trays 23 are arranged in parallel.

[0024] With such a device, the printing paper conveyed by the paper conveyance guide device 1 is It is conveyed while being attracted to the surface of the mesh-like endless belt 12, and the mesh-like endless belt 12 protrudes. At the leading end of the sheet, as shown by arrow F in FIG. It is designed to be taken out and stored on top of it.

[0025] Then, as the printing paper is discharged from the plate-making printing device, the slider 16 is sequentially raised. By lowering the printing paper, the printing paper is discharged one after another toward each tray 23. It will be stored.

[0026] In this way, the printed paper is sucked into the mesh belt, transported, and distributed to each tray. With this type of sorter, the rollers and guide plates do not scrape the image surface immediately after printing. This has the advantage of not causing image stains.

[0027] Figure 3 shows an example of the operation panel and control system of a prepress printing device to which a sorter is connected. vinegar. The operation panel is equipped with a key to select whether or not to use the sorter. Press the sorter use key 45 to turn on the LED lamp 46 to enter the sort mode (sort mode). mode), and the CPU 200, which performs overall control, acts as a control means. Then, the sorter's rocking motor 7 is rotated for a predetermined period of time, and the paper conveyance guide device 1 is moved downward. It oscillates to position D, which is the first position shown by the solid line in Fig. 1, and the plate making and printing device moves. All the sheets ejected from the machine are sent to the sorter.

[0028] If you press the sorter use key 45 on the operation panel again to turn off the LED lamp 46, The sorter's rocking motor 7 rotates again for a predetermined period of time, and this time the paper conveyance guide device 1 is raised. It swings toward the second position C, which is indicated by the chain line in Figure 1, and the screen is moved away from the plate-making and printing device. All the ejected printing paper is ejected and stacked on a dedicated paper ejection tray 42. Ru. In this case, the paper conveyance guide device 1 is retracted upward from the path P of the printing paper and moved downward. This does not prevent the paper from being ejected to the paper ejection tray 42 on the other side.

[0029] FIG. 4 is a diagram simply showing the path of the paper. In sorted mode, a route like G is taken, and in non-sorted mode, a route like H is taken. take the road. Note that the upper guide roller 15 is not one long roller, but is separated into two. The rollers 15 are provided only at both ends of the endless mesh belt 12, and the rollers 15 are used for printing. This prevents the image surface of the paper from being scratched. Also, the paper ejection tray on the paper ejection tray 42 The ID guide 43 is a foldable type, and when using a sorter, it must be folded down. Before use, swing the paper conveyance guide device 1 downward so that it does not become an obstacle. is the best way.

[0030] The conveyance speed of the paper conveyance guide device 1 is the same as that when the plate-making printing device is printing at the maximum speed. can be set to a speed approximately equal to the paper output speed of the sorter. Transport of printing paper becomes stable.

[0031] In addition, when printing on thick paper, even the sorter in the example may not work depending on the thickness. Since it is not possible to collate, in that case, change to non-sort mode and directly The sheets are stacked and stored on the paper discharge tray 42. However, as shown in Figure 7, This is a significant improvement over conventional sorters that cannot print on thick paper at all.

[0032] The sorter of this invention is suitable for printing machines with different heights of printing paper outlets from the floor. can also be easily accommodated. Figure 5 shows the implementation of positioning by detecting the angle of the paper conveyance guide device of the sorter. FIG. 4 is a detailed diagram illustrating an example; As mentioned above, the worm 5 and the semicircular worm wheel 6 are engaged with each other, and the Due to the rotation of the motor 7, the paper conveyance guide device 1 moves inside the roller 3 as shown by the arrow. It is designed to oscillate around the central axis. On the other hand, the bracket fixed to the sorter body Sensors 25 and 26 are provided on the cut 24 to detect the swing angle. On top of the semicircular worm wheel 6 is a detection plate 2 fixed with screws 27. 8 is provided. Then, the projection 28a of the detection plate 28 is connected to the sensor 25 or 26. By pressing the filler part, the angle of the paper conveyance guide device 1 can be detected. Wear.

[0033] FIG. 5 shows the sort mode, in which the protrusion 28a is pushing the sensor 25. However, in the non-sort mode, the motor 7 rotates and the paper conveyance guide device 1 moves upward. When the protrusion 28a of the detection plate presses the sensor 26, the control device is activated. All CPUs 200 control the motor 7 to stop.

[0034] According to such a device, the operator loosens the screw 27 and locks the detection plate 28. By moving the semicircular worm wheel 6 around the center axis of the roller 3, Therefore, the rocking stop position of the paper conveyance guide device 1 in sort mode and non-sort mode Since the position can be adjusted, the paper conveyance guide device 1 can be adjusted to the height of the paper outlet of the printing device. can be easily adapted to the

[0035] In the above embodiment, the paper guide unit guides and transports the printing paper. A case has been described in which the sheet conveyance guide device 1 is configured to have the following functions. Like this For example, printing paper ejected from a forced paper ejection device 35 as a paper ejection means may be used as a paper ejection means. It is possible to reliably convey and guide all the way to the reticulated endless belt 12. However, the paper ejection hand When the distance from the stage to the transport means is short, or when the slope is not facing upward, etc. may be a guide plate that does not have a conveyance function.

[0036]

As described above, according to the present invention, in the invention of claim 1, from the main body of the collating device A swingably supported paper guide section is provided, and the paper guide section is used to guide the paper from the paper ejection means of the printing device. The paper is shifted between the first position where the paper is received and the second position where the paper is retracted upward from the path from which the paper is ejected. In collation mode, set the paper guide to the first position. The paper can be guided to the conveying means of the collating device.

[0037] On the other hand, in the loading mode, by setting the paper guide section to the second position, the paper draft The inside does not interfere with paper ejection. For this reason, the printing device has an optimally designed You can use the dedicated paper ejection means as is, and as a result, the paper ejection It is no longer necessary to separately provide a tray above the collating device or on the downstream side of the collating device. Reduces the height and installation space of the collating device, lowers costs, and improves conveyance performance. can be achieved.

[0038] Furthermore, even when a large amount of paper is loaded on the paper output tray, the paper output is well aligned, so the paper output can be easily aligned. It is possible to prevent the occurrence of jams, and it is also possible to print and discharge thick paper.

[0039] On the other hand, such an online collation device can be optional; Users who do not need this can choose a printing device that only has a paper output tray. or Even if it is an online sorter, if you remove it from the printing device, it will remain in the same state. Another advantage is that it can be used as a printing device in the same state.

[0040] According to the invention of claim 2, in addition to the above, a conveyance function is added to the paper guide section. If the paper guide section slopes upward toward the downstream side or becomes longer, Even if there is a paper sheet, the paper can be reliably guided to the conveyance means.
