Description

  The present invention relates to a sheet-fed printing machine that detects whether a sheet is dropped or accumulated in the middle of a path for conveying a sheet of paper, metal, synthetic resin, or the like as a printed material of the sheet-fed printing machine.

  Conventionally, for example, in a sheet-fed printing press (hereinafter referred to as “first conventional apparatus”) which is a multicolor printing press, the outline of the configuration is sequentially supplied from the supply side of the sheet 16 as shown in FIG. The paper unit 1 includes a plurality of sets of printing units 3a to 3d, a paper discharge cylinder 21, a stacking unit 22, and the like. In this sheet-fed printing press, the sheets 16 fed one by one from the sheet feeding unit 1 are positioned by the register unit 2, accelerated by the swing gripper 4, and then delivered to the sheet feeding cylinder 5. Further, a blanket cylinder 14a that forms the first-stage printing section 3a is provided with a front end of the sheet 16 held by a gripping claw 8 of the impression cylinder 6a (the claw 8 is also provided in each of the impression cylinders 6b to 6d). The first color is printed by being fed between the impression cylinders 6a.

  The sheet 16 after the first color printing is sent out from between the blanket cylinder 14a and the impression cylinder 6a, and is added to the gripping nail 8 of the intermediate cylinder 7 existing between the first-stage printing unit 3a and the next-stage printing unit 3b. Handed over. Then, the sheet 16 held in the intermediate cylinder 7 is replaced by the gripping claws 8 of the impression cylinder 6b which is the next printing section 3b, and is sent between the blanket cylinder 14b and the impression cylinder 6b. Second color printing is performed. Similarly, multi-color printing is sequentially performed on the sheet 16 in each of the printing units 3c and 3d arranged in the subsequent stage, and multi-color printing is performed between the blanket 14d and the impression cylinder 6d of the final printing unit 3d. The passed sheets 16 are stacked on the stacking unit 22 through the discharge cylinder 21.

  On the other hand, in the sheet-fed printing press in the first conventional apparatus, for example, in the intermediate cylinder 7 located in the middle between the first-stage printing unit 3a and the next-stage printing unit 3b, the lower side 15 thereof, as shown in FIG. When the intermediate cylinder 7 rotates in the direction of the arrow, the rear end of the sheet 16 hangs down due to its gravity, and it is shown in FIG. Such a sheet guide is provided. That is, the seat guide has a plurality of guides 9 fixed in a direction substantially orthogonal to the plurality of supports 11 laid horizontally between the frames 10 (the same direction as the frame 10 direction) in the width direction (support 11 direction). It is provided in a strip shape and is arranged below the intermediate cylinder so that a predetermined gap exists from the intermediate cylinder 7 as a whole. The sheets 16 from the sheet feeding unit 1 are always accurately separated one by one and are not always sent out at a fixed interval, but sometimes they are sent out two times or sent out at an illegal interval. Most of such illegally fed sheets are detected by the register 2 and the machine is stopped and eliminated.

  However, the sheet that has missed the detection may be picked up by the swing gripper 4, sent from the paper feed cylinder 5 to the impression cylinder 6 a, and further sent to the next intermediate cylinder 7. In this case, the gripping claw 8 may be released in the middle of the conveyance path during printing and fall on the sheet guide 9 under the intermediate cylinder 15. The dropped sheet 17 is often in a state indicated by a dotted line in FIG. In the case of dropping, cylinder printing from the dropped cylinder to the impression cylinders 6b to 6d occurs in the subsequent printing units 3b to 3d, and unnecessary images are printed one after another on the back side of the subsequent sheets, resulting in defective paper. . Further, when several sheets are accumulated, the intermediate cylinder 7 is wound up by being rotated, and is caught in the changeover portion 26 between the intermediate cylinder 7 and the impression cylinder 6, so that the impression cylinders 6b to 6d and each intermediate cylinder 7 are bent. It will cause problems.

  In order to prevent this, a reflection type detector 13 is placed on the support 12 of the sheet guide under the intermediate cylinder 7 to detect whether or not there is a sheet 16 dropped on the guide 9. The reflection type detector 13 is a known detector in which a light projecting portion and a light receiving portion are integrated, and the detector 13 receives a light beam reflected by the sheet 16 from the detector 13 and the sheet 16 is present. Judge. Of course, when the reflected light from the sheet 16 that normally passes does not react and receives reflected light for a certain time or longer, it is determined that the sheet 16 is present, and the sheet 16 is positioned on the sheet guide. A control device (not shown) for notifying that the camera is falling is provided.

  Further, as a second conventional apparatus related to another sheet-fed printing machine, for example, a technique described in Japanese Patent Laid-Open No. 5-269611 (“Patent Document 1”) is known. That is, this second conventional apparatus is provided with a conveyor belt that is operated by a driving mechanism below several stages of printing units. When a sheet falls when passing through the printing unit, the falling sheet is transferred to the conveyor belt. It is dropped and moved to a position where it can be easily recovered by operating the conveyor belt and easily recovered.

Japanese Patent Laid-Open No. 5-269961

However, in the first conventional apparatus, when the sheet 16 is thick paper and has high rigidity, the distance a from the detector 13 increases as in the sheet 18 indicated by the dotted line in FIG. As shown in FIG. 10, when the sheet 29 falls off the center portion of the guide 9 and falls to an undetectable portion of the detector 13, the fall of the sheet 29 itself cannot be detected. In these cases, it is impossible to detect early that the defective printed sheets 18 and 29 are present on the sheet guide, or, due to this, a plurality of stacked sheets are caught and bitten. As a result, there is a problem that a cylinder bending phenomenon is caused in the impression cylinders 6a to 6d and the intermediate cylinder 7.
The second conventional apparatus has a structure that does not have a sheet guide as in the first conventional apparatus, and it is a technique that does not need to detect the presence or absence of a sheet that falls on the sheet guide. It is only what moved to a position where it can be easily taken out.

  The present invention was devised for the purpose of solving the above-mentioned problems, and dropped out in the middle of a path for transporting sheets of paper, metal, synthetic resin materials, etc., as printed matter of a sheet-fed printing press. Even if a sheet falls on the sheet guide, it is immediately detected and removed by early detection.As a result, the sheet is stuck in the intermediate cylinder and impression cylinder without being noticed of the fall. It is an object of the present invention to provide a sheet-fed printing machine that can prevent the occurrence of bending and effectively prevent the bending phenomenon.

  In order to solve the above problems, the following measures are taken in the present invention. That is, the invention according to claim 1 is a sheet-fed printing press having a sheet guide curved along the intermediate cylinder at a lower part of the intermediate cylinder, and is provided upstream of the rotation direction of the intermediate cylinder. Position one of the electromagnetic wave transmitter and the electromagnetic wave receiver below the vicinity of one curved end near the end of the seat guide, and a position on the downstream side in the rotational direction of the intermediate cylinder from the center of the sheet guide In addition, either one of the electromagnetic wave transmitter or the electromagnetic wave receiver is disposed below the vicinity of the curved end portion opposite to the vicinity of the curved end portion where the electromagnetic wave transmitter or the electromagnetic wave receiver is disposed. It was decided.

  Further, in addition to the configuration of the sheet-fed printing press according to claim 1, the invention according to claim 2 is formed by the electromagnetic wave transmitter and the electromagnetic wave receiver, and includes a blocking detection unit that detects the presence or absence of electromagnetic wave blocking. An interruption time calculating means for measuring an electromagnetic wave interruption time when an electromagnetic wave interruption is detected by the interruption detection means, and an interruption time determining means for determining whether or not the interruption time measured by the interruption time calculation means has passed a predetermined time. And the sheet-fed printing press only when the electromagnetic wave interruption is not detected by the interruption detection means or when the interruption time calculation interruption means determines that the interruption time is within a predetermined time even if the electromagnetic wave interruption is detected. And a printing system control means for controlling the operation so that the operation can be continued.

  A third aspect of the present invention relates to the sheet-fed printing press according to the first or second aspect, wherein the electromagnetic wave transmitter or the electromagnetic wave receiver is formed by a light emitter or a light receiver that transmits or receives visible light. It is characterized by that.

  According to the sheet-fed printing press according to the first aspect of the present invention, either the electromagnetic wave transmitter or the electromagnetic wave receiver is disposed below one of the curved end portions near the end portion of the sheet guide, and the electromagnetic wave The curved end portion where either the transmitter or the electromagnetic wave receiver is disposed at a position downstream of the sheet guide central portion in the rotation direction of the intermediate cylinder and either the electromagnetic wave transmitter or the electromagnetic wave receiver is disposed. It is arranged below the vicinity of the curved end facing the vicinity. For this reason, the electromagnetic wave transmitted from the electromagnetic wave transmitter toward the electromagnetic wave receiver is a bow that crosses the inner space of the curved sheet guide in the range of the upstream side of the intermediate cylinder in the rotational direction and the downstream side thereof. It passes through a path like a tool string. Therefore, when the sheet is not dropped on the sheet guide, the electromagnetic wave passage is not blocked, so the electromagnetic wave receiver receives the electromagnetic wave, and the printing machine does not cause defective printing. It can be detected that the vehicle is in an operating state.

  On the other hand, if the sheet is received by the sheet guide disposed below the intermediate cylinder, even if the sheet is lifted from the curved sheet guide, Regardless of the position where the sheet is received on the downstream side in the rotational direction, that is, the position where the sheet is received, the path of the electromagnetic wave is always blocked by the sheet and cannot be received. Therefore, since the electromagnetic wave emitted from the electromagnetic wave transmitting unit does not reach the electromagnetic wave receiving unit, it can be detected that the sheet has fallen on the sheet guide and is in an abnormal state that induces defective printing.

  As a result, according to the sheet-fed printing press according to the present invention, it is possible to early detect the presence of a sheet that has been defectively printed depending on whether electromagnetic waves are input to the receiving unit, and to detect a defective sheet In such a case, the operation of the printing press is immediately stopped and the defective sheet is removed from the sheet guide, so that the occurrence rate of defective printing can be minimized and the print quality can be remarkably improved. In addition, it is possible to avoid the accumulation of defective printed sheets by removing immediately, and thus torsional phenomenon caused by the accumulated sheet having a thickness being caught between the intermediate cylinder and the impression cylinder as it is. In addition to greatly improving the service life of the printing press, it is possible to obtain a sheet-fed printing press with high print quality.

  According to the second aspect of the present invention, the sheet-fed printing press according to the first aspect further includes a blocking detection unit that detects the presence or absence of electromagnetic wave blocking, a blocking time calculation unit that measures electromagnetic wave blocking time, and a blocking time. Since it includes a cut-off time judging means for judging whether or not a predetermined time has passed and a printing system control means for controlling the operation of the sheet-fed printing press so that it can be stopped and stopped, the cut-off detecting means is in an electromagnetic wave cut-off state. If it is not detected, or if it is determined that the interruption time measured by the interruption time calculation means is within a predetermined time even if the electromagnetic wave interruption state is detected, the defective sheet has fallen onto the sheet guide and is received. It comes to detect that there is no normal operating condition. For this reason, the sheet-fed printing press performs a continuous operation by a command signal from the printing system control means.

  On the contrary, when the electromagnetic wave interruption is detected by the interruption detection means and the electromagnetic wave interruption time measured by the interruption time calculating means exceeds a predetermined time, the printing system control means has caused the sheet-fed printing press to generate a defective sheet. Recognize that As a result, the printing system control means stops the operation of the sheet-fed printing press, so that the defective sheet can be removed from the sheet guide by the operator. Thus, according to the sheet-fed printing press according to the second aspect of the present invention, in order to enable early detection and removal of a defective sheet by using these automatic control systems, the loss reduction rate and the print quality can be reliably determined. As a result, it is possible to obtain a sheet-fed printing press excellent in quality control that can handle various sheets.

  According to a third aspect of the present invention, the electromagnetic wave transmitter or the electromagnetic wave receiver, which is a cut-off detecting means as a sensor means for detecting the presence or absence of the electromagnetic wave cut-off, is transmitted to or received from a visible light. This is advantageous because it is easy to maintain and manage these light emitting and receiving devices and can be manufactured at low cost.

The best mode for carrying out the present invention will be described with reference to FIGS.
Note that substantially the same members and equivalent members as those of the above-described conventional apparatus are denoted by the same reference numerals as those shown in FIGS. 6 to 10 and their detailed description is omitted. The basic configuration of the sheet-fed printing press according to the present embodiment is almost the same as the basic configuration of the sheet-fed printing press in the above-described conventional apparatus in FIGS. I will explain only. Further, the dimensions, materials, shapes, relative positions, etc. of the components described in this embodiment are not intended to limit the scope of the present invention only to specific examples unless otherwise specified. It is only a thing.

  That is, in FIG. 1 to FIG. 3, the sheet-fed printing press of the present embodiment is different from the above-described conventional device in the configuration in the configuration in which the reflection type detector 13 is conventionally arranged at the center of the guide 9. Instead of this, as shown in FIGS. 1 and 2, the optical axis 25 extends from a position exceeding the center of the range of the intermediate lower cylinder 15 to a position corresponding to the end of the dropped sheet 17 (FIGS. 3), for example, the light emitter 19 attached to the support 11 fixed in the direction orthogonal to the frame 10 via the attachment plate 23, and the attachment plate 24 to another support 11 similarly. It differs in the structure which installed the light receiver 20 attached via. The portions 27 and 28 through which the optical axis 25 does not pass are in a range smaller than the size of the sheet having the minimum area. That is, the light emitter 19 is disposed below one curved end near the end of the sheet guide 40, and the light receiver 20 is positioned downstream of the center of the sheet guide 40 in the rotation direction of the intermediate cylinder 7 and the light emitter. 19 is disposed below the vicinity of the other curved end portion of the sheet guide 40 facing the vicinity of the curved end portion where 19 is disposed. For this reason, the light traveling from the light emitter 19 toward the light receiver 20 is in the range upstream and downstream in the rotational direction of the intermediate cylinder 7, and without interfering with the guide 9 of the sheet guide 40. A part of the inner space below the intermediate body 15 formed with the guide 40 passes through a path like a string of a bow as the optical axis 25.

  Thereby, when the sheet is received by the sheet guide 40, the sheet 25 (see FIG. 9) is lifted from the curved surface of the sheet guide 40 as well as the sheet 25 is received in the state shown in FIG. 3 or even if the sheet 29 exists at a position biased downstream in the rotational direction of the intermediate cylinder 7 as shown in FIG. 3, that is, at what position the sheet is received. Even in such a case, since the optical axis 25 always intersects with the sheets 25, 18, and 29, the light beam cannot be received by the light receiver 20. On the contrary, when there is no sheet in the sheet guide 40, the light from the light emitter 19 is always received by the light receiver. In this way, the light emitter 19 and the light receiver 20 form a light shielding detector incorporated in the printing system control device as will be described later.

  On the other hand, the sheet-fed printing press according to the present embodiment is provided with a printing system control device 50 shown in FIG. 4, thereby controlling the operation of the printing press. That is, the printing system control device 50 includes a light-blocking detection unit 51 that detects whether or not light is received from the light emitter 19 and the light receiver 20, light emission information to the light emitter 19, light reception information from the light receiver 20, and light-shielding time. Information relating to the information, control information for controlling each part of the printing press, information relating to an operation command signal for controlling the operation of the printing press, etc., and a shut-off time when the light-shielding detecting means 51 detects light shut-off. The shading time calculating unit 53 to measure, the shading time determining means 54 for determining whether the shading time measured by the shading time calculating unit 53 has passed a predetermined time, the printing system control unit 55, and the printing machine And an operation output unit 56 for controlling the operation output. When the light shielding state is not detected by the light shielding detection unit 51 or when the light shielding time calculation unit 53 determines that the light shielding time is within a predetermined time, the printing system control unit 55 determines that the defective sheet is a sheet. It is determined that it is in a normal state where it has not fallen on the guide 40, and control is performed to continue the operation of the sheet-fed printing press.

  Next, the procedure for detecting the presence or absence of a sheet by the operation of the printing system control apparatus will be described with reference to the flowchart of FIG. That is, when the main switch of the sheet-fed printing press is turned on and the operation is started (step S1), the machine is operated in the normal printing mode. In this operation state mode, the light receiving unit 20 monitors the light receiving state of the light from the light emitter 19 by the light blocking detection unit 51 (step S2), and detects whether light is detected or not detected (step S3). If it is determined in step S3 that the light blocking detection unit 51 has received light, that is, if a state where light is not blocked is detected, it is determined that there is no defective sheet on the sheet guide 40, and the process proceeds to step S6. A control signal is output to the operation output unit 56 so as to jump and continue the operation of the printing press, and the continuous operation is continued to perform printing. After step S6 has elapsed, the process returns to step S2 again, and the control after step S3 is performed.

  On the other hand, if the light blocking detector 51 does not receive light in step S3, the light blocking time is measured by the light blocking time calculator 53 in step S4, and the light blocking time is within a predetermined time by the light blocking time determination means 54. Is determined (step S5). Whether or not it is within the predetermined time is determined when a certain amount of time is required to cross the optical axis 25 when a normal sheet passes through the sheet guide 40 when the light shielding time is within the predetermined time range. Therefore, the time required for the passage is set as an allowable range, and the control for determining that the light shielding within the allowable range is not an abnormal state but a normal state is performed. For this reason, if it is determined in step S5 that the light blocking time is within the predetermined time, the process proceeds to step S6, and the operation of the printing press is continued in the normal (normal) operation mode. If it is determined in step S5 that the light shielding time has exceeded a predetermined time, that is, the allowable time, the operation output unit 56 switches the operation of the printing press to the stop mode by a control signal from the printing system control unit 55. To stop (step S7). With the operation stopped, the operator removes the defective sheets 17 (see FIG. 1), 18 (see FIG. 9), and 29 (see FIG. 3) present on the sheet guide 40. Thereby, the machine can be returned to a normal state.

  As described above, according to the present embodiment, not only the sheet 17 on the sheet guide 40 at the center of the intermediate lower cylinder 15 but also the sheet 18 away from the guide 9 is also centered as shown in FIG. The sheet 29 that is off the part also necessarily blocks the optical axis 25. This makes it possible to reliably detect a dropped sheet that could not be detected by the conventional method. As a result, it is possible not only to detect defective printing at an early stage and minimize the occurrence rate of defective printing, but also to cause accidents such as bending of the body by biting into the cylinder without accumulating falling sheets. Will be able to prevent.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention, the present invention is not limited to this embodiment. It is included in the scope of the invention.
That is, in the above-described embodiment, the electromagnetic wave used for the electromagnetic wave transmitter and the electromagnetic wave receiver has been described by taking as an example the case where the light emitter 19 and the light receiver 20 adopting visible light are used. Instead, infrared light or laser light may be used, and ultrasonic waves and the like are collectively referred to as electromagnetic waves, and various types can be used without departing from the gist of the present invention.
Needless to say, the positions where the light emitter 19 and the light receiver 20 are provided may be replaced with each other. Thereby, it becomes possible to raise the freedom degree of attachment.
In addition, although one light shielding detection unit 51 including the pair of light emitters 19 and light receivers 20 is provided, the number of light shielding detection units may be two or more. Thereby, detection accuracy can be increased.
Furthermore, the sheet guide may be a plate-like one, and a portion through which electromagnetic waves pass may be cut out.
