  FIG. 1 is a front view schematically showing the whole collating apparatus A to be used in the present invention, which collates a plurality of continuous sheets. The collating apparatus A has a configuration in which a plurality of, for example, seven paper feeders 2a, 2b, 2c, 2d, 2e, 2f, and 2g are provided along the conveying line 1. A space is formed between the four upstream paper feeders 2a to 2d and the three downstream paper feeders 2e to 2g. In this portion, for example, a slitter device 3a and a punching device 3b are provided. The 1st process part 3 which has is provided. Further, on the downstream side of the three downstream paper feeders 2e to 2g, for example, a second processing section 4 having a horizontal sewing machine processing device 4a and a sheet cutting device 4b, and further a product discharge to the downstream side thereof. A conveyor 5 is arranged.

  Each of the paper feeders 2a to 2g is of a pin feed system, and continuous paper 6a, 6b, 6c, 6d, 6e, 6f, 6g having feed holes at both ends in the width direction is supported in a roll shape. The continuous sheets 6a to 6g are timed by the pin feed control unit 7 provided with the sheet feeders 2a to 2g, respectively, and are fed out and fed to the conveyance line 1, and the conveyance line 1 It is conveyed in the state collated by the pin tractor 8 provided in the.

  FIG. 2 shows an example of the pin feed control unit 7, which is composed of a dancer roll device 9, a feed control device 10, and a glue application device 11 arranged in order from the upstream side in the paper feeding direction.

  The dancer roll device 9 has a dancer roll 12 that adjusts the length of the transport path of the continuous paper 6b supplied from the roll paper by moving in the vertical direction.

The bracket 44 is fixed to a proper position by a fixed clamp mechanism (not shown) at a predetermined position after rotation. Further, the brackets 44 that support both ends of both the rolls 42 and 43 are coupled by the connecting and fixing shaft 45 so as not to be twisted.

  FIG. 7 shows a product B with a concealment seal manufactured by the apparatus of the present invention. This is one of the above-mentioned patterns 46 of the continuous paper 6a ′ as an attachment board on which predetermined patterns 46 are printed at predetermined intervals. The part is concealed by a cut sheet 47, which is before being cut into individual sheets.

  Below, the preparation work of the said product B with a concealment seal is demonstrated.

  A continuous paper 6a ′ as an attachment board is supported by the paper feeder 2a on the upstream side of the collating apparatus A, and this is passed through the glue application unit 22 of the cut sheet attaching apparatus 20 and passed through the pin wheel 33. Then pass the paper through the conveying line 1. The continuous paper 6a ′ at this time is sent by the pin tractor 8 and the pin wheel 33.

  On the other hand, the continuous sheet 6e ′ to be the cut sheet 47 is supported by the paper feeder 2e immediately downstream of the cut sheet pasting apparatus 20, and this is fed to the feed control roll 23, the mark sensor 24, the cut sheet pasting unit 21, and the like. The paper is passed through the cutting device 25.

  By driving the collating apparatus A in this state, in the glue application unit 22, the continuous paper 6 a ′ serving as a pasteboard is transferred to each pattern 46 of the continuous paper 6 a ′ by the glue application unit 32 of the glue application unit 22. After the paste is applied in a predetermined pattern to the predetermined position, the pin tractor 8 passes through the pin wheel 33 and is sent to the conveying line 1 at a constant speed.

  When the continuous paper 6a 'is sent, the conveyance of the continuous paper 6a' is detected by the operation of the tension roll 41, and the detection result is converted into an electric signal to drive the feed control roll 39. The feed control roll 39 is rotationally controlled at a feed speed so that the tension roll 41 is held at a predetermined angular position. The feeding operation at the feeding control roll 39 is performed without slipping by the pressing of the nip rollers 39a that are in rolling contact with the feeding control roll 39.

  When the continuous paper 6 a ′ is conveyed in this way, the tension adjustment braking device 40 operates on the upstream side of the glue application unit 32, and the slight tension generated by the tension roll 41 is amplified by the tension adjustment braking device 40. Adjusted. The braking force at this time is adjusted to increase / decrease by changing the winding angle around the fixed roll 43, and within the tension limit for pin feed, and for stable pattern glue application at the glue application part 32. The necessary tension can be generated. The braking of the continuous paper 6 a ′ at this time is adjusted by rotating the bracket 44 of the tension adjustment braking device 40 to change the winding angle of the continuous paper 6 a ′ with respect to the fixed roll 43.

  Note that the tension adjustment braking device 40 that performs the braking action at the glue application unit 32 replaces the fixed roll 43 with a rotating roller without using the above-described configuration, and controls the rotating shaft by electrical or fluid pressure control. A brake unit capable of adjusting power may be provided, and the tension of the continuous paper may be adjusted by the brake unit.

  Thereby, the glue adhering to the surface of the paste plate cylinder 35 of the glue application section 32 can be applied to the application position of the continuous paper 6a ′ with high accuracy. Further, in cooperation with the tension roll 41, the urging force toward the glue receiving cylinder 36 can be properly maintained with respect to the continuous paper 6a '. Further, at the time of applying glue, the paste-applying plate surface is attracted to the plate surface side by the peeling force from the continuous paper 6a ′, and the continuous paper 6a ′ may become unstable. This action can avoid this instability phenomenon, and the effect becomes more remarkable as the production speed increases.

  On the other hand, in the cut sheet pasting unit 21 in the driving state of the collating apparatus A, the continuous paper 6e ′ serving as a cut sheet supported by the paper feeder 2e is fed by the feeding control roll 23 with the glue applying unit 22. The timing sensor 48 detects the timing mark 48 printed on the continuous paper 6e 'every time one surface of the pattern 46 printed on the continuous paper 6a' serving as an attachment base sheet transported and fed at is conveyed. It is drawn out over a predetermined length, for example, 1/2 the length of the picture 46 while detecting at.

  The continuous paper 6e 'is pressed by a pressing roller 30 on a receiving cylinder 26 rotating at a peripheral speed that is the same as the conveying speed of the conveying line 1 of the cutting device 25, and is wound even in a sliding state. As described above, when the continuous paper 6e 'is fed out for a predetermined length, the cut cylinder 27 is rotated and cut into a cut sheet 47 having a predetermined length.

  At this time, a suction force due to negative pressure acts on the outer peripheral surface from the position facing the cut cylinder 27 of the receiving cylinder 26 to the position facing the impression cylinder 31 which is in rolling contact with the conveyance line 1. Therefore, the cut sheet 47 is moved to a position where the cut sheet 47 is attracted to the circumferential surface of the receiving cylinder 26 and faces the impression cylinder 31. At this time, the impression cylinder 31 is contacted and operated. Affixed at a predetermined position on the sheet 6a '.

  Since the feeding speed of the continuous paper 6e ′ by the feeding control roll 23 is slower than the peripheral speed of the receiving cylinder 26 by the interval between the cut sheets 47, the continuous paper 6e ′ before being cut by the cutting cylinder 27 is Then, the sheet is fed to the cutting position while slipping with respect to the peripheral surface of the receiving cylinder 26 while being pressed by the pressing roller 30.

  In the cut sheet pasting unit 21, an example is shown in which the rotation of the feeding control roll 23 and the cut drum 27 is operated in synchronization with the detection signal of the mark sensor 24 for detecting the timing mark. The operation of the feeding control roll 23 and the cut drum 27 may be controlled in synchronism with the transport speed of the transport line 1 without using a detection signal from the mark sensor. In this case, the timing mark 48 of the continuous paper 6e 'is controlled. Becomes useless.
