  The side guide 32 is provided so that it can be tilted approximately 90 degrees toward the inner side in the width direction with the pin 329 as a fulcrum, as shown by a one-dot chain line in FIG. The side guide 33 is the same.

  The side guides 32 and 33 and the front end guide 34 can be positioned at the “paper guide position”, “paper take-out position”, and “guide retractable position” by the two moving mechanisms 5 and 6. FIG. 7 is a schematic plan view for explaining these positions. The broken lines in FIGS. 7A and 7B indicate the size of the paper.

  The “paper guide position” is the position shown in FIG. 7A. At this position, the side guides 32 and 33 are in a position for guiding the side edge in the width direction of the received paper, and the leading edge guide. Reference numeral 34 denotes a position for guiding the leading edge of the received paper in the discharge direction. Here, the “guide position” of the side guides 32 and 33 is a little inside the position of the side edge in the width direction of the paper when the paper is dropped in a U-shape for the stable fall of the paper. Is the position.

  The “paper take-out position” is the position shown in FIG. 7B. At this position, the side guides 32 and 33 are located on the outer side in the width direction from the received paper, and the leading edge guide 34 is , Located downstream of the receiving sheet in the discharge direction.

  “Guide storing position” is the position shown in FIG. 7C. In this position, the side guides 32 and 33 are positioned outside in the width direction from the maximum sheet to be printed, and The tip guide 34 is located between the pair of side guides 32 and 33. At the “guide retractable position”, the side guides 32, 33 and the front guide 34 are placed on the paper receiving base 31 as a work before the paper receiving device 3 is cleared to the above-described non-extending state with respect to the printing press main body 2. Can be stored. Here, “storing” means that the side guides 32 and 33 and the front end guide 34 are respectively tilted so as to overlap the paper tray 31.

  The paper receiving device 3 further includes a paper presence sensor 7 (FIG. 2) that detects whether or not the paper is on the paper receiving base 31, and a movement instruction input unit that inputs an instruction to the movement control unit. ing. Specifically, the movement instruction input means is one control switch 8 (FIGS. 1 and 2), but is not limited thereto, and may be a display button provided on the operation panel 22, for example. As shown in FIG. 2, the sheet presence / absence sensor 7 is provided at the center on the upstream side in the discharge direction of the receiving surface 311 of the paper receiving base 31. The control switch 8 is provided on the downstream side in the discharge direction on one side surface of the paper receiving tray 31.

The movement control unit is configured to perform the following control. That is, when the control switch 8 is pressed, the movement control unit receives the detection result of the paper presence / absence sensor 7 and controls the both movement mechanisms 5 and 6 as follows.
(A) When there is no sheet, the side guides 32 and 33 and the front end guide 34 are moved to a guide storing position.
(B) When there is a sheet, the side guides 32 and 33 and the front end guide 34 are moved to the sheet take-out position.

  Next, the operation of the printing press 100 provided with the paper receiving device 3 of the present embodiment will be described.

(1) When “auto mode” is selected on the operation panel 22, when the paper size button A4 on the operation panel 22 is pressed, the side guides 32 and 33 and the front guide 34 automatically correspond to the A4 size. Move to the paper guide position (FIG. 7A).

  On the other hand, when “manual mode” is selected on the operation panel 22, the operation differs depending on whether “standard”, “user setting”, or “fine adjustment” is selected on the operation panel 22. That is, when “standard” is selected, when the paper size button A4 on the operation panel 22 is pressed, the side guides 32 and 33 and the front guide 34 automatically become the paper guide positions corresponding to the A4 size (FIG. 7). Move to (A)). In addition, when “user setting” is selected, when the memory number button on the operation panel 22 is pressed, the side guides 32 and 33 and the tip guide 34 are automatically placed at the user setting positions stored in the memory numbers. And move. When “fine adjustment” is selected, the side guides 32 and 33 and the tip guide 34 are moved to arbitrary positions by performing a key operation on the operation panel 22. However, in any position, the side guides 32 and 33 and the front end guide 34 guide the paper.

(2) Next, when the printing process of the printing press 100 is started, the paper is sent from the paper feeding device 1 to the printing unit, subjected to printing processing, and from the paper discharging unit to the paper receiving platform 31 of the paper receiving device 3. Is discharged. As a result, in the paper receiving apparatus 3, the printed paper is stacked on the paper receiving base 31 while being guided by the side guides 32 and 33 and the front end guide 34.

  Note that the leading edge of the paper discharged onto the paper receiving tray 31 collides with the leading guide 34, but plate members 342 and 343 made of an elastic material are provided on the surface 341 of the leading guide 34. Therefore, (i) the paper can be prevented from bouncing back in the discharge direction, and therefore the rear edge of the paper can be quickly dropped by holding the front edge of the paper on the front guide 34. It is possible to prevent the leading edge of the subsequent sheet from colliding with the trailing edge and damage both of them, and (ii) to prevent the leading edge of the sheet from being damaged.

(3) When the printing process is completed, the control switch 8 is pressed. Thereby, the paper receiving apparatus 3 operates as shown in the flowchart of FIG.

(3-1) First, it is determined whether or not the control switch 8 is turned on (step (hereinafter referred to as S) 81). If it is not on, it returns to the print processing end state. If it is turned on, it is determined whether or not the paper presence sensor 7 is turned on (S82).

(3-2a) When the sheet presence sensor 7 is turned on, it is determined that there is a sheet, and the side guides 32 and 33 and the front guide 34 are moved to the sheet take-out position (S83). Thus, the operator can easily take out the paper stacked on the paper receiving tray 31 without the side guides 32 and 33 and the front end guide 34 getting in the way.

(3-2b) If the sheet presence / absence sensor 7 is not turned on, it is determined that there is no sheet, and the side guides 32 and 33 and the front guide 34 move to the guide retractable position (S84). Thus, the operator can store the side guides 32 and 33 and the tip guide 34. The storage operation is performed as follows. That is, first, as shown in FIG. 9A, the tip guide 34 is tilted approximately 90 degrees toward the downstream side in the discharge direction and is stacked on the paper tray 31. Next, as shown in FIG. 9B, the side guide 33 is tilted approximately 90 degrees toward the inner side in the width direction and overlapped with the paper receiving base 31 and the front end guide 34. Then, as shown in FIG. 9C, the side guide 32 is tilted approximately 90 degrees toward the inner side in the width direction and overlapped with the paper receiving base 31, the leading end guide 34, and the side guide 33. As a result, the side guides 32 and 33 and the leading end guide 34 are overlapped with the paper receiving base 31, that is, the side guides 32 and 33 and the leading end guide 34 are accommodated in the paper receiving base 31. As shown by the broken line in FIG. 1, the base 31 can be cleaned up to the printing press main body 2.

  In this storing operation, since the tip guide 34 is located between the side guides 32 and 33 in the guide storing position, the side guides 32 and 33 cannot be tilted unless the tip guide 34 is tilted first. . Accordingly, it is possible to prevent the guides from being put in the wrong order, and therefore, the guide overlap state on the paper receiving tray 31 can be prevented from being distorted, and the paper receiving device 3 can be properly disposed.

  In the storing operation, when the side guide 32 or the side guide 33 is tilted after the tip guide 34 is tilted, the plate members 342 and 343 of the tip guide 34 function as cushions. Can be prevented.

  As described above, according to the paper receiving device 3 of the present embodiment, the side guides 32 and 33 and the front end guide 34 can be automatically moved to the guide retractable position, so that the guide is easily stored. be able to. In addition, since the side guides 32 and 33 and the front end guide 34 can be stored in the paper receiving base 31 without changing the order, the paper receiving device 3 can be properly disposed.

[Second Embodiment]
This embodiment is different from the first embodiment in the following points.

  That is, the paper receiving device 3 further has warning means for displaying various warning contents on the operation panel 22.

Further, the movement control unit is configured to perform the following control. That is, when the control switch 8 is pressed, the movement control unit determines whether the pressing time is less than the predetermined time or longer than the predetermined time and receives the detection result of the paper presence / absence sensor 7 to move the both moving mechanisms 5 and 6 next. Control like this. The predetermined time is, for example, 2 seconds.
(I) When the pressing time is less than the predetermined time and there is a sheet, the side guides 32 and 33 and the front guide 34 are moved to the sheet take-out position.
(Ii) When the pressing time is less than the predetermined time and there is no paper, the side guides 32 and 33 and the front guide 34 are moved to the paper guide position.
(Iii) When the pressing time is equal to or longer than the predetermined time and there is a sheet, a warning unit warns that there is a sheet. The warning that there is a sheet is a content that requires the removal of the sheet, for example, “please remove the sheet”.
(Iv) When the pressing time is equal to or longer than the predetermined time and there is no sheet, the side guides 32 and 33 and the front end guide 34 are moved to the guide retractable position.

  Next, the operation of the printing press 100 provided with the paper receiving device 3 of the present embodiment will be described.

(1) The selection of “auto mode” or “manual mode” on the operation panel 22 is the same as in the first embodiment. The side guides 32 and 33 and the front end guide 34 serve to guide the paper.

(2) Next, when the printing process of the printing press 100 is started, as in the case of the first embodiment, the printed paper is guided by the side guides 32 and 33 and the front end guide 34 while being guided by the paper tray. It is loaded on 31.

(3) When the printing process is completed, the control switch 8 is pressed. Thereby, the paper receiving apparatus 3 operates as shown in the flowchart of FIG.

(3-1) First, it is determined whether or not the control switch 8 is turned on (S101). If it is not on, it returns to the print processing end state. If it is turned on, it is determined whether it has been turned on for a predetermined time or more (S102).

(3-2a) When the control switch 8 is not turned on for a predetermined time or more, that is, when the control switch 8 is turned on for less than the predetermined time, it is determined whether or not the sheet presence sensor 7 is turned on (S103).

(3-2a-a) When the sheet presence sensor 7 is turned on, it is determined that there is a sheet, and the side guides 32 and 33 and the front guide 34 are moved to the sheet take-out position (S104). Thus, the operator can easily take out the paper stacked on the paper receiving tray 31 without the side guides 32 and 33 and the front end guide 34 getting in the way.

(3-2a-b) If the paper presence sensor 7 is not turned on, it is determined that there is no paper, and the side guides 32 and 33 and the front guide 34 move to the paper guide position (S105). Thereby, the printing process can be continued.

(3-2b) On the other hand, if the control switch 8 is turned on for a predetermined time or more, it is determined whether or not the paper presence sensor 7 is turned on (S106).

(3-2b-a) When the sheet presence sensor 7 is turned on, it is determined that there is a sheet, and for example, a warning “Please remove the sheet” is displayed on the operation panel 22 (S107). Further, it is determined whether or not the sheet presence sensor 7 is turned on (S108). If the sheet presence sensor 7 is turned on, it is determined that the sheet has not been removed, and a warning is displayed again. If the sheet presence / absence sensor 7 is not turned on, it is determined that the sheet has been removed, and the side guides 32 and 33 and the front end guide 34 are moved to the guide retractable positions (S109).

(3-2b-b) If the paper presence sensor 7 is not turned on, it is determined that there is no paper, and the side guides 32 and 33 and the front guide 34 move to the guide retractable positions (S109). Thus, the operator can store the side guides 32 and 33 and the tip guide 34. The storing operation is the same as that in the first embodiment.

  As described above, according to the paper receiving device 3 of the present embodiment, the same effects as those of the first embodiment can be exhibited. Moreover, since not only the guide storing position and the paper take-out position but also the paper guide position and warning can be set by pressing the one control switch 8, many operation states can be set by a simple operation. Efficiency can be improved.

[Third Embodiment]
This embodiment is different from the second embodiment in the following points.

  That is, the paper receiving device 3 further includes a guide fall sensor that detects that at least one of the side guides 32 and 33 is fallen.

  In the present embodiment, the guide fall sensor is also used by the paper presence sensor 7. The sheet presence / absence sensor 7 detects that the side guide is tilted when detecting “paper present” after detecting “paper out” even once after the end of the printing process. Yes.

  The movement control unit further performs the following control. That is, when the sheet presence / absence sensor 7 which is a guide tilt sensor detects that the side guide 32 and / or the side guide 33 is tilted, both the side guides 32 and 33 and the tip guide 34 are not moved. The moving mechanisms 5 and 6 are controlled, and a warning means is used to warn that the side guide has fallen. Note that the warning that the side guide is tilted is a content that requires the side guide to be rebuilt, for example, “please raise the side guide”.

  Next, the operation of the printing press 100 provided with the paper receiving device 3 of the present embodiment will be described.

(1) The selection of “auto mode” or “manual mode” on the operation panel 22 is the same as in the first embodiment. The side guides 32 and 33 and the front end guide 34 serve to guide the paper.

(2) Next, when the printing process of the printing press 100 is started, as in the case of the first embodiment, the printed paper is guided by the side guides 32 and 33 and the front end guide 34 while being guided by the paper tray. It is loaded on 31.

(3) Next, when the printing process is completed, the control switch 8 is pressed. Thereby, the paper receiving apparatus 3 operates from S101 to S103 in the flowchart of FIG.

(4) When the sheet presence / absence sensor 7 is turned on, the operation is performed as shown in the flowchart of FIG. 11 following “* 1” of FIG. That is, first, it is determined whether or not the sheet presence sensor 7 is turned on after being turned off even once (S111).

(4-1a) If the sheet presence / absence sensor 7 has never been turned off, it is determined that the side guides are not tilted, and the side guides 32 and 33 and the front end guide 34 move to the sheet take-out position (S112). ).

(4-1b) If the sheet presence sensor 7 is turned on after being turned off even once, it is determined that the side guide is tilted, and the both moving mechanisms 5 are prevented from moving the side guides 32 and 33 and the front end guide 34. , 6 are controlled, for example, a warning “Please set up the side guide” is displayed on the operation panel 22 (S113). The worker who has received this warning visually checks whether or not the side guide has fallen. If the side guide has fallen, the worker resets the side guide. Then, the contents for asking the operator whether or not to move the side guides 32 and 33 and the front end guide 34 to the paper take-out position are displayed on the operation panel 22 (S114).

(4-1b-a) When the operator permits the movement, the side guides 32 and 33 and the front end guide 34 move to the paper take-out position (S115).

(4-1b-b) If the worker does not permit movement, the process returns to S113.

  As described above, according to the paper receiving device 3 of the present embodiment, the same effects as those of the second embodiment can be exhibited. In addition, since the guide collapse sensor is provided, it is possible to prevent the guide in the collapsed state from being forcibly moved, and therefore it is possible to prevent the guide from being broken and the moving mechanism from being broken. Further, since the sheet presence / absence sensor 7 also serves as a guide fall sensor, the configuration can be simplified.

[Fourth Embodiment]
This embodiment is different from the third embodiment in the following points. That is, a guide fall sensor different from the paper presence sensor 7 is provided.

  Next, the operation of the printing press 100 provided with the paper receiving device 3 of the present embodiment will be described.

(1) The selection of “auto mode” or “manual mode” on the operation panel 22 is the same as in the first embodiment. The side guides 32 and 33 and the front end guide 34 serve to guide the paper.

(2) Next, when the printing process of the printing press 100 is started, as in the case of the first embodiment, the printed paper is guided by the side guides 32 and 33 and the front end guide 34 while being guided by the paper tray. It is loaded on 31.

(3) Next, when the printing process is completed, the control switch 8 is pressed. Thereby, the paper receiving apparatus 3 operates from S101 to S103 in the flowchart of FIG.

(4) Then, the operation is performed as shown in the flow chart of FIG. 12 continuing from “* 1” of FIG. That is, first, it is determined whether the guide fall sensor has detected the fall of the side guide (S121).

(4-1a) If the guide tilt sensor has not detected, the side guides are not tilted, and the side guides 32 and 33 and the leading end guide 34 are moved to the paper take-out position (S122).

(4-1b) When the guide fall sensor detects, since the side guide has fallen, both the moving mechanisms 5 and 6 are controlled so as not to move the side guides 32 and 33 and the tip guide 34. For example, A warning “Please stand the side guide” is displayed on the operation panel 22 (S123). The worker who has received this warning visually checks whether or not the side guide has fallen. If the side guide has fallen, the worker resets the side guide. Then, contents for asking the operator whether or not to move the side guides 32 and 33 and the front end guide 34 to the sheet take-out position are displayed on the operation panel 22 (S124).

(4-1b-a) When the operator permits the movement, the side guides 32 and 33 and the front end guide 34 move to the paper take-out position (S125).

(4-1b-b) When the worker does not permit movement, the process returns to S123.

  As described above, according to the paper receiving device 3 of the present embodiment, the same effects as those of the third embodiment can be exhibited. In addition, since the guide fall sensor can reliably detect the fall of the guide, it is possible to prevent the guide fall from being erroneously detected and performing a useless operation.

[Fifth Embodiment]
This embodiment is different from the first embodiment in the following points.

That is, the movement control unit is configured to perform the following control. That is, the movement control unit receives the detection result of the paper presence sensor 7 when the control switch 8 is pressed, and further determines whether the pressing time is less than a predetermined time or more than a predetermined time. 6 is controlled as follows.
(I) When there is a sheet, both moving mechanisms 5 and 6 are controlled so that the side guides 32 and 33 and the leading end guide 34 are moved to the sheet take-out position.
(Ii) When there is no paper and the pressing time is less than the predetermined time, both the moving mechanisms 5 and 6 are controlled so that the side guides 32 and 33 and the front guide 34 are moved to the paper guide position.
(Iii) When there is no sheet and the pressing time is a predetermined time or longer, both the moving mechanisms 5 and 6 are controlled so that the side guides 32 and 33 and the front end guide 34 are moved to the guide retractable positions.

  Next, the operation of the printing press 100 provided with the paper receiving device 3 of the present embodiment will be described.

(1) The selection of “auto mode” or “manual mode” on the operation panel 22 is the same as in the first embodiment. The side guides 32 and 33 and the front end guide 34 serve to guide the paper.

(2) Next, when the printing process of the printing press 100 is started, as in the case of the first embodiment, the printed paper is guided by the side guides 32 and 33 and the front end guide 34 while being guided by the paper tray. It is loaded on 31.

(3) When the printing process is completed, the control switch 8 is pressed. Thereby, the paper receiving apparatus 3 operates as shown in the flowchart of FIG.

(3-2a) When the sheet presence sensor 7 is turned on, it is determined that there is a sheet, and the side guides 32 and 33 and the front end guide 34 move to the sheet take-out position (S133). Thus, the operator can easily take out the paper stacked on the paper receiving tray 31 without the side guides 32 and 33 and the front end guide 34 getting in the way.

(3-2b) If the sheet presence sensor 7 is not turned on, it is determined that there is no sheet, and it is determined whether the control switch 8 has been turned on for a predetermined time or more (S134).

(3-3a) When the control switch 8 is turned on for a predetermined time or more, it is determined that there is no sheet, and the side guides 32 and 33 and the front guide 34 are moved to the guide retractable positions (S135). Thus, the operator can store the side guides 32 and 33 and the tip guide 34. The storing operation is the same as that in the first embodiment.

(3-3b) When the control switch 8 is not turned on for a predetermined time or more, that is, when the control switch 8 is turned on for less than a predetermined time, it is determined that there is no sheet, and the side guides 32 and 33 and the front guide 34 are It moves to the paper guide position (S136). Thereby, the printing process can be continued.

  As described above, according to the paper receiving device 3 of the present embodiment, the same effects as those of the first embodiment can be exhibited. Moreover, since not only the guide storing position and the paper take-out position but also the paper guide position can be set by pressing the one control switch 8, many operation states can be set by a simple operation, and therefore work efficiency can be improved. It can be improved.

[Another embodiment]
As shown by “* 1” in FIG. 13, the fifth embodiment can be modified as in the third embodiment and the fourth embodiment related to the second embodiment.

  Note that the paper receiving device 3 of the present invention may include the following means.

(I) New and old size comparison means This means compares the currently selected paper size with the previously selected paper size in the paper receiving device 3, the size has been changed, and the paper presence sensor 7 is turned on. A predetermined warning is displayed on the operation panel 22. The predetermined warning indicates that there is a risk of paper damage if the current size is smaller. If the current size is larger, a message with a different size is displayed. It is a content that informs that there is a risk of mixing. According to this means, it is possible to prevent paper damage and paper mixture in the paper receiving device 3.

(II) Guide confirmation warning means This means is used when the paper is discharged from the printing machine main body 2 to the paper receiving device 3, that is, in the paper discharge portion, when the paper jam occurs a predetermined number of times or more, the side guide 32, In order to ask the operator to confirm the setting of the positions of the guide 33 and the tip guide 34, for example, a warning such as “Please check the guide position” is displayed on the operation panel 22. According to this means, it is possible to prevent a setting error of the guide position that causes paper jam.

(III) Paper Feed / Paper Receipt Size Comparing Means In this means, when the “auto mode” is selected, the paper size (plate making size) designated to be printed on the operation panel 22 and the paper feeding device 1 The size of the paper set in the paper (paper feeding size) is compared, and if both sizes are different, a warning that “the paper size is set incorrectly” is displayed on the operation panel 22. If the plate-making size and the paper feed size are different, there is a risk of jamming in the paper discharge unit. Therefore, according to this means, it is possible to prevent a jam from occurring in the paper discharge unit. The warning may be displayed when the prepress / print key on the operation panel 22 is pressed.

  As a method for detecting the paper feed size, for example, the methods described in JP-A-57-107337 and JP-A-54-77965 can be used. The former is a method in which a change in resistance value from a reference position is obtained by a potentiometer that rotates in conjunction with the movement of the width guide, and the size in the width direction of the sheet is calculated from the change. The latter is a method in which a plurality of reflection sensors are arranged along the carry-out direction, and the paper discharge direction size is calculated based on the presence or absence of detection by each sensor.

  The paper receiving apparatus of the present invention can be easily cleaned up and can be properly cleaned up, and thus has great industrial utility value.
