No. 60, Japanese Patent Publication No. 62-10895, Japanese Patent Publication No. 4
The one shown in Japanese Patent Publication No. 7903 is known.

However, these known apparatuses have a structure in which a heavy object moves at high speed every time a small amount of printed matter is taken out from the printed matter line, and the number of printed matter taken out is apt to be excessive or insufficient, and the reliability is low. , Such as a method that is likely to cause inconvenience in the subsequent process due to the removal of printed matter, which is not suitable for taking out printing paper with low rigidity, or a special configuration that is difficult to add to conventional models. There were issues that were difficult to adapt to improvement.

The present invention is relatively simple and does not require movement of a heavy body, is compact and highly space-saving, and can be easily attached to an existing high-speed printed material conveying path.
The probability of failure repair is low, and the desired printed matter from the printed matter line,
Accurate and reliable extraction can be performed without causing inconvenience in the subsequent process, and a plurality of extracted printed matter samples can be stored in a identifiable manner without any additional work later, and stored. It is also an object of the present invention to solve various problems that the above-mentioned conventional devices have at once by providing a printed matter extracting device that is easy to take out printed matter samples and is suitable for batch inspection of printed matter samples.

[0007]

In order to solve the above problems, the present invention provides the following constitutions. That is, an intermediate conveyance path having an upstream end and a downstream end is interposed in a conveyor conveyance path that conveys printed matter as a front-tilted row in which the printed matter is partially overlapped, and a sampling conveyance for extracting the printed matter from the conveyor conveyance path. The path is provided such that the upstream end thereof faces the downstream end of the intermediate transfer path, and the midstream and the downstream thereof rise above the conveyor transfer path on the downstream side of the intermediate transfer path. A switching member that links or disconnects the upstream end of the transport path and the downstream end of the intermediate transport path, and blocks the printed material at the downstream end of the conveyor transport path upstream of the intermediate transport path. A blocking member for stopping and a mark on at least one of the stopped printed materials which is temporarily stopped between the upstream end and the downstream end of the extraction transportation path and which is conveyed by this transportation path. A labeling mechanism for attaching and a printed material storage means for guiding and storing a printed material transported on the transport path are provided in the vicinity of the downstream end of the transport path, and an upstream operation is performed by a linking operation of the blocking member and the switching member. A desired number of copies of the printed matter are extracted from the printed matter on the intermediate conveyance path separated from the printed matter on the side, transferred to the conveyance path, a mark is attached to the printed matter, and the printed matter is stored.

The blocking member is manually activated by a switch operation, or a counting device for counting the number of prints is provided upstream of the blocking member.
Each time the counting device reaches a predetermined number of countings, the blocking member is automatically activated.

Regarding the activation of the switching member, when the tail end of the preceding printed matter line that has been blocked from being blocked by the blocking member passes to a position upstream by the distance L from the downstream end of the intermediate conveyance path. When a detection sensor that emits a signal is provided, the overlapping pitch of the printed matter is P, the length of the printed matter is m, the number of printed matter to be extracted is n, and the transport distance corresponding to the operation delay of the switching member is α, L is determined by the equation L = (P * (n-1)) + m + [alpha].

Another configuration relating to the activation of the switching member is to provide a rotary encoder linked to the shaft of a pulley for driving the intermediate conveying path, when the count of pulse signals emitted from the rotary encoder reaches a predetermined count value. Then, the switching member is activated.

A second blocking member for blocking the printed matter transported on the transport path is provided at the downstream end of the intermediate transport path.

[0012]

According to the above construction, when the printed matter sample is taken out from the printed matter train being conveyed on the conveyor conveying path, for example, manually by pressing the push button switch, or a desired count value of the printed matter counter, for example, 50.
A sampling device activation signal is automatically output for every 00 copies. Then, the blocking member provided at the downstream end of the transport path on the upstream side of the intermediate transport path is activated, and the printed matter row conveyed on this transporting path is set to the preceding printed matter row and the blocked printed matter row subsequent to the printed matter row. Block to create the desired spacing between and.

Due to this blocking, the preceding printed matter line separated from the succeeding printed matter line is continuously conveyed by the intermediate conveying path, and the preceding printed matter row is conveyed by the conveying path at a desired distance, that is, in the intermediate conveying path. When the length L minus the distance L or the desired pulse signal count value by the rotary encoder is carried, the switching member operates toward the downstream end of the carrying path and the upstream end of the extraction carrying path. Is linked to the downstream end of the intermediate conveyance path.

By this linkage, while the leading end of the printed matter has already passed through the downstream end of the conveying path to the downstream side conveying path, all the succeeding printed matter following this printed matter is conveyed by the intermediate conveying path. Transfer to the sampling transport path.

Then, the marker applying mechanism is operated to apply the marker to the printed matter stopped at the position where the marker applying mechanism operates in the extracting and conveying path by stopping the extracting and conveying path. After that, the driving of the sampling conveyance path is restarted, and the printed matter is conveyed and guided toward the printed matter storage means by the sampling conveyance path and the guide means.

The blocking member releases the blocking at the time when the desired spacing is completed in the printed matter row. Further, the switching member operates so as to disconnect the extraction conveyance path from the intermediate conveyance path when the space formed in the printed matter row reaches the downstream end of the intermediate conveyance path.

In particular, the second blocking member effectively acts on the withdrawal of the printed matter when the printed matter forms a forward tilt row with a constant overlapping pitch in the state after the cut leading fold and the trailing fold.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, generally, an upstream side device 1 and a downstream side device 2 such as a rotary press are connected by a conveyor line 3 (hereinafter referred to as a conveyor conveyor path 3) using a belt conveyor. , The printed matter that has been printed and folded by the upstream side device 1 is sequentially placed on the upper surface of the conveyor transport path 3 in a forward inclined row with a constant overlapping pitch, and the printed matter row is conveyed to the downstream side apparatus 2 and the downstream side thereof. In the device 2, for example, printed materials are collected and bundled for each predetermined number of copies. Such a printed matter processing system is conventionally well known.

On the other hand, in the present invention, the upstream side device 1
Between the downstream side device 2 and the downstream side device 2, that is, the intermediate portion thereof, that is, the upstream transport path 3a and the downstream transport path 3c.
An intermediate conveyance path 3b is provided between and. Each of these conveyance paths is constituted by an independent belt conveyor composed of an endless belt spanning at least two pulleys. The intermediate conveyance path 3b is the upstream conveyance path 3
Installation at a position slightly lower than a and slightly higher than the downstream conveying path 3c facilitates the extraction work according to the present invention. The carrying direction and carrying speed of each carrying path are variable in accordance with the operating speed of the rotary press while maintaining the same direction (leftward in the embodiment of FIG. 1) and the same speed.

The extraction / conveyance path for extracting the printed matter from the conveyor conveyance path 3 is, as shown by reference numeral 4 in FIG.
Its upstream end faces the downstream end of the intermediate conveyance path 3b, and
It is provided in a state where the downstream end rises from the middle stream to the upstream side of the downstream transport path 3c.

The extracting / conveying path 4 has a belt conveyor 5 on one side and a belt conveyor 6 on the other side which rotate in opposite directions.
The printed matter extracted from the conveyor conveyance path 3 is conveyed upward while being sandwiched between the pair of same-direction traveling sections.

Relay pulleys 5a and 6a are provided at intermediate positions of the belt conveyors 5 and 6 on one side and the other side, which operate close to each other. The pair of relay pulleys have both the bending function and the driving function of the pair of belt conveyors.

First, as shown in the first embodiment, the belt conveyors 5 and 6 on the one side and the other side are structurally structured such that the pair of relay pulleys 5a and 6a serve as bending points, respectively, and the intermediate conveying path 3b. The upstream portion provided toward the downstream end of the, and the middle stream and the downstream portion provided toward the upper side are linked with each other.

Further, as schematically shown in the embodiment of FIG. 2, the belt conveyors 5 and 6 on one side and the other side are driven by an independent drive means 7 of a different system from the drive of the conveyor transport path 3, respectively. It is driven by being transmitted via the relay pulleys 5a and 6a. That is, the rotation is transmitted from the drive shaft 7a of the independent drive means 7 to the shaft of the relay pulley 5a of the belt conveyor 5 on one side, and further, the gear 5b coaxial with the relay pulley 5a and the belt conveyor 6 on the other side. The reverse rotation is transmitted to the belt conveyor 6 on the other side by the meshing of the relay pulley 6a and the coaxial gear 6b.

Such a pair of belt conveyors 5 and 6
The transport speed of the extraction transport path 4 consisting of is set so as to be higher than the maximum transport speed of the conveyor transport path 3 and always kept constant.

A switching member 8 for picking up the printed matter on the conveyor conveying path 3 and introducing the printed matter to the conveying path 4
Is provided at the upstream end of the extraction conveyance path 4 provided toward the downstream end of the intermediate conveyance path 3b. As shown in FIG.
The switching member 8 is composed of a tapered free end and a base end fixed to the shaft 8a. Both ends of the shaft 8a are rotatably attached to a frame (not shown), and further, an arm 8b is provided at one end thereof, and the free end of the arm is connected to the tip of the rod of the fluid pressure cylinder 8c. Therefore, the switching member 8 is pivotally displaced about the shaft 8a by the operation of the fluid pressure cylinder 8c, and thus the extension of the rod pulls out the switching member 8 and links the transport path 4 and the intermediate transport path 3b (see FIG. 1). And 2) (represented by the chain double-dashed line), and the shortening of the rod brings the switching member 8 into both the disconnected positions (shown in solid lines in FIGS. 1 and 2).

A blocking member 9 for dividing the printed matter line conveyed on the conveyor conveyance path 3 and temporarily stopping the progress of the succeeding printed matter line is provided at the downstream end of the upstream conveyance path 3a in the conveyor conveyance path 3. It is installed at a position where it can be operated. The upper end of the blocking member 9 is supported by the lower end of the rod of the fluid pressure cylinder 9a which is appropriately fixed, as shown in the embodiment of FIG. Therefore, the blocking member 9 is provided between the blocking position by the extension of the rod (shown by the two-dot chain line in FIGS. 1 and 2) and the standby position by the shortening thereof (shown by the solid line in FIGS. 1 and 2). Displace.

The blocking member 9 is activated manually or automatically. In the case of manual operation, a start signal is issued by, for example, depressing a push button switch (not shown). On the other hand, in the case of automatically extracting a desired number of copies, for example, 5000 copies,
As shown in FIG. 7, a counting device 9f for counting printed matter is provided on the conveyor conveyance path upstream of the blocking member or on the rotary press, and the blocking device 9f is provided each time the counting device reaches a predetermined number. The blocking member 9 is automatically activated.

When the blocking of the blocking member 9 stops the progress of the succeeding printed matter row, the stopped subsequent printing material stands up along the blocking member by the forward force applied thereto. Trying to climb up. Therefore, in order to suppress the rising, a rising suppressing member 9b is provided so as to project rearward from an intermediate portion of the rear surface of the blocking member 9. Since the rising prevention member 9b is fixed to the blocking member 9, the rising blocking member 9b descends as the blocking member 9 descends, and retreats upward as it is displaced upward.

Even if the leading edge of the succeeding printed matter line is restrained from advancing due to the lowering of the blocking member 9, the traveling displacement of the upstream conveying path 3a is still continuing. The overlapping pitch is shortened, that is, front jamming occurs, and in an extreme case, overtaking occurs and the rows are disturbed. On the other hand, when the rising prevention plate 9b is released due to the rise of the blocking member 9, the rising phenomenon of the leading edge of the succeeding printed matter row reoccurs in conjunction with it. Therefore, in order to prevent such an adverse effect that the row of the subsequent printed matter row is disturbed and the leading edge rising phenomenon occur, first, the succeeding printed matter row posture control material 9c is provided at the downstream end of the upstream transport path 3a.
Is fixedly installed at a position that is closest to and is inclined so as to gradually increase toward the upstream end from that position, and secondly, the subsequent printed material line is lifted along the lower side of the upstream transport path 3a. The material 9d is installed in a state of being supported by the rod of the fluid pressure cylinder 9e, and in conjunction with the lowering of the blocking member 9, the rod of the fluid pressure cylinder 9e extends so that the subsequent printed material lifting material 9d travels in the upstream transport path 3a. The succeeding printed matter line, which has been prevented from advancing by being displaced above the level, is separated from the upstream conveyance path 3a, and is lifted and supported. The succeeding printed material line lifting material 9d moves back below the upstream conveying path 3a (the solid line position in FIG. 1) by shortening the rod of the fluid pressure cylinder 9e in conjunction with the upward displacement of the blocking member 9.

When the blocking member 9 descends into the printed matter row, the printed matter row upstream from the lowered position is prevented from moving, while the printed matter row downstream from the lowered position advances onto the intermediate conveying path 3b. Transport continues. If it is assumed that the switching member 8 is operated at the same time as the blocking member 9 is lowered to bring the downstream end of the intermediate conveyance path 3b into a linked posture, all the printed matter rows on the intermediate conveyance path 3b are extracted and conveyed. It is possible to make it flow into No. 4. However, normally, the number of printed matter rows required for one sampling inspection is 1 to 3 copies, so the switching member 8
Is adjusted and controlled so that it operates with a predetermined time delay from the time when the blocking member 9 is lowered. This time adjustment can be performed by detecting the transport distance regardless of the transport speed of the intermediate transport path 3b. Switching member 8
Two examples of the conveying distance detecting means of the intermediate conveying path 3b for controlling the operation timing of are shown below.

In the embodiment shown in FIG. 3, the distance L is from the downstream end of the intermediate conveying path 3b, that is, the operating position of the switching member 8.
A detection sensor 8d for transmitting a start signal of the switching member 8 is provided at a position upstream by the length of. This detection sensor
When the trailing edge of the preceding printed matter line that has been blocked from being blocked by the blocking member passes through that position, the detection sensor is a detection unit that outputs an operation signal of the switching member 8. In FIG. 3, P is the overlapping pitch of the printed matter, n is the number of printed matter to be extracted, m is the length of the printed matter, and α is the transport distance corresponding to the operation delay of the switching member 8, and the distance L is L = (P × (n− 1)) + m + α.

In the embodiment shown in FIG. 4, a rotary encoder 8e linked to the shaft of a pulley that drives the intermediate conveying path 3b is provided, and the count value based on the pulse signal emitted from this rotary encoder is used as the conveying distance of the intermediate conveying path 3b. It is a detecting means that is obtained by conversion. This detecting means starts counting of pulse signals in synchronization with the operation of the blocking member 9 and activates the switching member 8 when the desired counting is reached. The count value of the pulse signal is cleared every time the switching member 8 is activated, in synchronization with it.

In the present invention, as shown in the illustrated embodiment,
The switching member 8 is arranged at the downstream end of the intermediate conveying path 3b in a posture in which the switching member 8 is linked from the direction opposite to the flow of the printed matter row, that is, from downstream to upstream. Therefore, in order to deal with this, the alignment state of the printed matter supplied on the conveyor conveyance path 3 is limited to the alignment state in which a constant overlapping pitch row is formed in a forward tilted state in which each tip is exposed on the upper surface of the row. In contrast to the above, it is unsuitable for aligning a rearwardly inclined printed matter row in which each rear end is exposed on the upper surface of the row.

Further, even when the printed materials are aligned in the above-mentioned posture, the front and rear ends of the printed materials are arranged in a crease leading break succeeding type array as shown in FIGS. 3 and 4. As shown in FIG. 3, the sheet is conveyed in two modes, that is, a break leading fold and trailing fold type array. In the latter case, that is, with respect to the formation of the printed matter row in the arrangement pattern of the break preceding fold and the succeeding fold type, it is difficult to expect reliable switching by the single lowering by the switching member 8. This is because the leading edge of the switching member 8 may be inserted between the cuts.

Therefore, as shown in FIG. 5, a position immediately before the switching member 8 that can be operated toward the downstream end of the intermediate conveying path 3b in preparation for the case of the printed matter arranging system of the break leading fold and the trailing type. The second blocking member 10 is provided on the. The upper end of the second blocking member 10 is supported by the lower end of the rod of the fluid pressure cylinder 10a which is appropriately fixed, as shown in the embodiment of FIG. Therefore, the second blocking member 10 is at the blocking position (see FIGS. 1 and 2) due to the extension of the rod.
(Indicated by the chain double-dashed line) and the standby position (Fig. 1
And (indicated by the solid line 2).

In the structure in which the second blocking member 10 is provided,
A timer (not shown) is activated by the descent activation signal, a signal is output after a proper set time is measured, and the switching member 8 is activated by the signal.

When the second blocking member 10 descends, the trailing printed matter line that has been blocked up rises upward along the second blocking member due to the transport forward force from the intermediate transport path 3b. To try. Therefore, in order to suppress the rising, a rising suppressing member 10b is provided so as to project rearward from the intermediate portion of the rear surface of the second blocking member 10. Since this rising prevention member 10b is fixed to the second blocking member 10, it is displaced as the second blocking member 10 moves up and down.

When the restraint from the rising restraining member 10b to the printed matter row is released as the second blocking member 10 rises, the leading edge of the succeeding printed matter row rises again in conjunction with the raising operation. To try. Therefore, in order to prevent the adverse effect, the succeeding printed matter line posture control material 10c is provided in the intermediate conveyance path 3
It is appropriately fixedly installed at a position which is closest to the conveying path 3b at the downstream end of b and maintains an inclined posture so that the conveying path 3b becomes gradually higher from there.

As shown in FIG. 1, a labeling mechanism 11 is provided between the upstream end and the downstream end of the extracting / conveying path 4. The marking mechanism 11 includes a marking head 11 a and the head 1 a.
A printed matter is provided between a fluid pressure cylinder 11b that supports 1a at the tip of a rod and moves it to a labeling position and a standby position, and a labeling head 11a that is provided facing the labeling head 11a and has moved to the labeling position. An auxiliary member 11c for sandwiching the marker and a printed material conveyed on the extraction conveyance path 4 are detected, and the printed material is extracted in order to stop the printed material on the extraction conveyance path 4 at a position facing the labeling position. It is constituted by a detection means 11d which outputs a stop signal of the independent drive means 7 of the transport path 4. The marking head 11a uses, for example, a numbering device (for example, numbering manufactured by Plus Co., Ltd.) whose printed number is changed by stamping operation. The fluid pressure cylinder 11b, the auxiliary member 11c, and the detection means 11d are appropriately fixed.

The marking head 11a may use an ink jet device instead of the numbering device. When the ink jet device is used, the marking head is replaced with a fluid pressure cylinder 11b for moving the ink jet device, and a driver (not shown) for operating the ink jet device that discharges the ink toward the printed matter and the driver control. A means such as a CPU (not shown) is used.

The detection means 11d shown in FIG. 1 detects the printed matter conveyed on the extracting and conveying path 4 upstream of the marking position, and adjusts the output timing of the stop signal through the timer 11e to adjust the printed matter. The stop position can be adjusted.

As another embodiment of this detecting means,
As shown in FIG. 6, the detection means 11f may be provided on the downstream side of the marking position to detect the printed matter, and the detection signal may be used as the stop signal.

It is also possible to provide a plurality of marking heads (for example, a numbering head and an ink jet head) so that markings can be applied to each of the plurality of printed matter taken out at once.

As shown in FIG. 1, the printed matter storage means 12 is provided near the downstream end of the extraction conveyance path 4 and above the intermediate conveyance path 3b. This printed matter storage means 12 is
At least the upper portion is a bottomed member which is open and provided with a cage on the four sides. In the embodiment of FIG. 1, the cage and the bottom of the four sides are in a state of being completely shielded, but as shown in the embodiment of FIG. Considering the convenience when taking out the stored printed matter,
You may have a continuous notch from the bottom to the upper side of the cover,
Further, the bottom may be an inclined bottom with the side on which the printed matter is placed raised.

The printed matter storage means 12 is appropriately fixed or is easily and removably supported by a properly fixed support member (not shown). Therefore, this can be replaced as appropriate, and the printed matter storage means 12 can be moved to another place while the extracted printed matter is stored, which is effective for continuous printing for a long time.

A guide means 13 is provided at the lower end of the extraction conveyance path 4.
Is provided. The guide means 13 regulates the traveling direction of the printed matter released from the extraction conveyance path 4, and the printed matter storage means 12
It is a regulating member that guides the printed matter so that the printed matter can enter the inside regularly and pile up. As shown in FIG. 1, the restriction member 13 is
One member may be formed in an appropriate shape, or a plurality of members may be combined (not shown). Control member 1
3 is fixed appropriately.

The operation of the above configuration will be described below. The printed matter extracting device having the above-described configuration is the upstream device 1,
With the downstream device 2, the upstream transport path 3a, the intermediate transport path 3b, and the downstream transport path 3c in the conveyor transport path 3 are aligned and operating, and the three transport paths are misaligned at a predetermined pitch. It operates so as to extract a predetermined number, for example, three copies of continuous printed matter from the printed matter train conveyed by 3a, 3b, and 3c.

First, the blocking member 9 of the printed matter extracting device is activated manually or automatically by outputting an activation signal. In the case of manual operation, the activation signal is output by the operation of the dedicated activation switch by the operator, for example, the depression operation of the push button switch (not shown).
Further, in the case of automatically extracting printed matter for each predetermined number, a counting device 9f for counting the number of printed matters counts up a preset number and outputs a signal each time it is reset. Alternatively, a signal may be set to be output every time the count value of the counting device 9f is added by a predetermined number, for example, 5000, and this output signal may be used as the activation signal.

When the activation signal is output, the fluid pressure cylinder 9a extends the rod, and the blocking member 9 supported by the tip of the rod moves to the position shown by the chain double-dashed line in FIG. Also, along with this operation, the fluid pressure cylinder 9
e extends the rod, and the succeeding printed material line lifting member 9d supported by the tip of the rod moves to the lifting position.
Then, the leading end of the upstream-side trailing end printed matter row whose leading end has not reached the blocking operation position is prevented from proceeding from the printed matter row moving from the upstream transport path 3a to the intermediate transport path 3b. , And is kept on the upstream transport path 3a. However, since the subsequent printed matter is still forced to move forward due to the conveying action of the upstream conveying path 3a, the leading end is tried to be smaller and the pitch between the leading ends thereof becomes smaller. Since it is prevented by the deterrent action, the extreme disturbance such that the succeeding printed matter overtakes the preceding printed matter does not occur. Further, due to the occurrence of the leading edge, a strong downward force is exerted on the printed matter on the leading side.
Since the contact with the transport surface of the upstream transport path 3a has been cut off and the upper transport path 3a has been lifted upward, these printed materials are not transferred.
No scratches and damage.

The preceding printed matter row which has not passed through the blocking of the blocking member 9 is moved to the intermediate transport path 3b and continues to be transported. As a result, a space is created between the blocked print line and the preceding print line (see FIG. 3).

As shown in FIG. 3, from the preceding printed matter row thus formed with intervals, the printed matter on the downstream side, for example, three copies, is extracted from the preceding printed matter row. A detection sensor 8d is provided at a position upstream by a distance where the leading edge of the third preceding printed matter reaches the downstream end of the intermediate conveyance path 3b, and when the sensor detects the passage of the tail of the printed matter row, a signal that detects this is output. By this signal, the second blocking member 10 and the switching member 8
However, it is activated by a slight advance of the second blocking member 10.

In this operation, in response to the detection signal, the fluid pressure cylinder 10a first extends the rod to the second blocking member 10 at the blocking position (shown by a chain double-dashed line in FIGS. 1 and 2). Along with the movement, a timer (not shown) is activated, and a predetermined time by this timer, for example,
A fluid pressure cylinder 8c for a switching member, shown in FIG. 2, extends the rod in response to an output signal obtained by measuring a time sufficient for the fluid pressure cylinder 10a to fully extend the rod, and switches the fluid through the arm 8b and the shaft 8a. Member 8
Is rotated to displace the extraction conveyance path 4 to a posture in which it is linked to the intermediate conveyance path 3b. Also, instead of the timer, the second
A detection means (not shown) for detecting the displacement of the blocking member 10 to the blocking position may be provided, and the detection signal of this detection means may be converted into an output signal obtained by timing of the timer.

At the blocking position, the second blocking member 10 keeps all of the printed matter to be extracted in the intermediate conveyance path 3b, and during that period, the extraction conveyance path 4 and the intermediate conveyance path 3b are linked by the switching member 8. To be done.

Waiting for the connection, the fluid pressure cylinder 10
Retracts the rod and moves the second blocking member 10 to the standby position (shown by the solid line in FIGS. 1 and 2). Due to this movement, the printed matter retained in the intermediate conveyance path 3b is
The intermediate conveyance path 3b is advanced by the conveyance action, is transferred to the extraction conveyance path 4 across the switching member 8, and is conveyed in the extraction conveyance path 4.

The signal for causing the rod of the fluid pressure cylinder 10a to contract is given a predetermined time of a timer (not shown) which is activated at the same time when the rod of the fluid pressure cylinder 8c is extended, that is, the fluid pressure cylinder 8c is activated. Any means such as an output signal due to the end of timing for a time sufficient to fully extend the rod or a detection signal from a detection means (not shown) for detecting the end of displacement of the switching member 8 to the linkage posture may be used.

When the switching member 8 reaches the linking posture, the printed matter whose leading end has already passed the downstream end of the intermediate conveyance path 3b is moved to the downstream conveyance path 3c by the conveyance action of the intermediate conveyance path 3b.

When the printed material to be extracted is conveyed in the extraction conveyance path 4 and its tail end has passed the downstream end of the intermediate conveyance path 3b, the fluid pressure cylinder 8c contracts its rod, and the arm 8b and the shaft 8a are passed through. Then, the switching member 8 is rotated to displace the extraction conveyance path 4 to the posture in which it is disconnected from the intermediate conveyance path 3b. Regarding the means for detecting that the tail end of the printed matter to be extracted has finished passing the downstream end of the intermediate conveyance path 3b, the switching member return detection sensor 8 of FIG.
It depends on the signal from f. Since the transport speed of the sampling transport path 4 is constant, a timer (not shown) that operates at the same time as the operation of the fluid pressure cylinder 10a is provided, and a signal is output after timing of an appropriate time. The rod of the fluid pressure cylinder 8c may be contracted.

The fact that the space between the printed matter rows is formed on the intermediate conveying path 3b can be known by, for example, detecting the operation start timing of the switching member 8 and the like. The fluid pressure cylinder 9a and the fluid pressure cylinder 9e both contract their rods, and the blocking member 9 and the lifting member 9d both move to the standby position shown by the solid line in FIG. Due to this movement, the conveyance of the printed matter row retained in the upstream conveyance path 3a is restarted.

The printed matter conveyed on the sampling conveyance path 4 is
It is detected by the detection means 11d. Detection means 11d
The output of this detection signal activates the timer 11e to measure the time until the printed matter reaches the position corresponding to the mark applying position of the sign applying mechanism 11. Timer 11
When the time elapses, the signal e outputs a signal to stop the independent drive means 7 (see FIG. 2) of the extraction conveyance path 4 and stop the operation of the extraction conveyance path 4. Therefore, the printed matter that has been conveyed on the extraction conveyance path 4 is stopped at a position between the marking head 11a and the auxiliary member 11c and very close to the auxiliary member 11c.

According to the output signal of the timer 11e,
The fluid pressure cylinder 11b operates one reciprocating motion to extend and retract the rod. Therefore, the labeling head 11a supported by the tip of the rod is moved to the labeling position by the expansion operation of the rod, and the stopped printed matter is sandwiched between the labeling head 11a and the auxiliary member 11c, A mark is given to the printed matter, that is, a different serial number is printed each time, and the printing is returned after printing.

In the marking by the ink jet device, more detailed information such as the rotary press number and the lot number can be printed as the marker by the instruction of the control means.

When the operation of the rod of the fluid pressure cylinder 11b is completed, the operation of the independent drive means 7 is restarted, and the printed matter with the mark is taken out by the pick-up conveying path 4 toward the downstream end of the conveying path 4. It will be restarted. Completion of the operation of the rod of the fluid pressure cylinder 11b is performed by an appropriate detection means (not shown).

The printed matter discharged from its downstream end by the conveying action of the extracting and conveying path 4 comes into contact with the guiding means 13, changes its direction according to its shape, and moves to the printed matter storing means 12 where it is stored. .

With the above, one extraction work is completed.

The printed matter storage means 12 sequentially piles up and stores the extracted printed matter from each time.
