And then folded in half along the longitudinal direction by a triangular plate 30 provided at the entrance of the folding machine 28. Subsequently, after being sandwiched between the lead-in rollers 31 a and 31 b and the nipping rollers 32 a and 32 b disposed below and sequentially rotated and transferred, they are fed between the saw cylinder 14 and the folding cylinder 3.
[0004]
As shown in FIG. 4B, the saw body 14 is provided with a saw base 33 along the axial direction on the outer peripheral surface, and a saw blade 34 is incorporated in the saw base 33. On the other hand, on the outer peripheral surface portion of the folding cylinder 3, a saw blade receiver 35 as a receiving member of the saw blade 34, a needle device provided with a needle 36 at the arm tip, and a folding blade 17 attached to the folding blade shaft 8 are provided. It has been. The saw blade receiver 35 is formed of an elastic body such as rubber, and extends along the axial direction of the folding cylinder 3 so as to correspond to the saw blade 34. The saw cylinder 14 and the folding cylinder 3 are configured to rotate oppositely in synchronization with each other in a state where phases are set so that the saw blade 34 and the saw blade receiver 35 correspond to each other.
[0005]
Further, the needle 36 of the needle device is attached to the tip of a needle arm assembled to the needle shaft, and is rotated from the outer peripheral surface of the folding cylinder 3 at a predetermined phase position while rotating in conjunction with the rotation of the folding cylinder 3. Come and go. That is, the web 26 is cut by the saw blade 34 and the saw blade receiver 35, and at the same time, the needle 36 protrudes from the surface of the folding cylinder 3 and pierces the leading end portion of the subsequent web 26. It is held by a needle, wound around the outer peripheral surface of the folding cylinder 3, and is rotated and transferred.
[0006]
Then, when the web 26 is rotated and transferred, and the central portion of the newspaper approaches the position immediately above the folding rollers 27a and 27b, the folding blade 17 is pushed into the intermediate portion of the folding rollers 27a and 27b, and the needle 36 is gradually retracted. The web 26 comes out of the web 26 and the rear end of the web 26 is cut by the engagement between the saw blade receiver 35 and the saw blade 34.
[0007]
With the cutting of the web 26, the next needle 36 (downstream in the rotational direction) close to the cutting position protrudes to hook the downstream end of the downstream web 26, and the signature 9 is produced one after another in the same manner as described above. .

It is. The impeller 37 is composed of a plurality of blades (blades) and is used in combination with a plurality of rows. The origami 39 transferred from the impeller 37 onto the paper discharge conveyor 29 is carried out to the outside in a state of being stacked in a roof tile shape.
[0009]
By the way, as shown in FIG. 5, the folding cylinder is composed of a folding cylinder 3 pivotally supported on the apparatus side frames 1 a and 1 b as main machine elements, and shafts (folding cylinder shafts) 4 a and 4 b at both ends of the folding cylinder 3. (Shown as 4 if not distinguished), a drive gear 5 fixed to the shaft end of one side (drive side) 4a of the folding cylinder shaft 4, a shaft 22 disposed inside the folding cylinder 3, a folding cylinder 3 includes a pair of arms 24a and 24b attached to the shaft 22 and a folding blade shaft 8 spanned between the arms 24a and 24b.
[0010]
The shaft 22 is supported on one side (drive side) on the shaft portion of the folding cylinder 3 via an eccentric bearing 6 and on the other side (operation side) via an eccentric bearing 7 fixed to the apparatus frame 1b. It is pivotally supported. A folding blade 17 is fixed to the folding blade shaft 8.
Furthermore, a gear 25 is attached to one end of the folding blade shaft 8. The gear 25 meshes with a gear 19 fixed to a shaft 20 supported by an eccentric bearing 6 fixed to the frame 1a via an intermediate gear 57 rotatably supported by an arm 24a. .
[0011]
In FIG. 5, S is the amount of eccentricity of the eccentric bearings 6 and 7, and the shaft 20 and the shaft 22 are connected to the folding cylinder shafts 4a and 4b by the amount of eccentricity S via these eccentric bearings 6 and 7. Eccentric.
The saw cylinder 14 engaged with the folding cylinder 3 is pivotally supported by the apparatus frames 1a and 1b at both ends of the shaft, and the gear 15 fixed to the driving-side shaft end is a folding cylinder shaft on one side (driving side). It is meshed with a drive gear 5 fixed to the shaft end of 4a, and the saw cylinder 14 and the folding cylinder 3 are rotated in opposition to each other. Further, a helical gear 40 is installed at the shaft end on the other side (operation side) of the saw cylinder 14 so as to be freely movable in the axial direction while being fixed in the rotational direction. The helical gear 40 is fixed to the shaft 22. It meshes with the helical gear 58.
[0012]
With such a configuration, the rotational driving force from the mechanical drive source is transmitted to the drive gear 5 fixed to the folding cylinder shaft 4a, and then the gear 15 and the saw cylinder 14 fixed to the shaft end of the saw cylinder 14 are provided. The helical gear 40, the helical gear 58, and the shaft 22 fixed to the other shaft end of the saw cylinder 14 are transmitted in this order to rotate the arms 24a and 24b. By the rotation of the arms 24a and 24b, the folding blade shaft 8, the intermediate gear 57, and the gear 25 are also rotated (revolved) around the shaft centers of the shaft 22 and the arms 24a and 24b, and the intermediate gear 57 that revolves around the fixed gear 19 is rotated. Then, the gear 25 and the blade shaft 8 rotate.
[0013]
Accordingly, the folding blade shaft 8 revolves around the outer periphery of the fixed gear 19 through the intermediate gear 57 as the folding cylinder 3 rotates, and rotates with a predetermined rotational speed ratio. The locus shown by the solid line is taken.

[0014]
The position of the fold at the center of the folding book 39 is adjusted by adjusting the timing of pushing the folding fold 17 into the folding roller 27. As shown in FIG. 5, the crease position adjustment can be performed by moving the helical gear 40 in the axial direction and relatively advancing or delaying it depending on the helical angle of the helical bar.
In this case, the movement of the helical gear 40 in the axial direction is caused by rotating a feed screw 51 having a male screw at one end by a motor 52 and moving the disc 50 having a female screw to be engaged with the male screw of the feed screw 51 in the axial direction. Move to. Since the rotation direction of the disk 50 is stopped by a rotation stopper (not shown), the disk 50 moves in the axial direction. Further, since the disc 50 is axially fixed and freely supported in the rotational direction with respect to the helical gear 40, when the circular plate 50 moves in the axial direction, the helical gear 40 also moves in the axial direction.
[0015]
As a result, the exit timing of the folding blade 17 changes as described above, and the crease position can be adjusted.
In FIG. 5, reference numeral 42 denotes a potentiometer that detects the current position of the fold position adjusting mechanism. In FIG. 5, 55 and 56 are oil chambers filled with oil that protects the engaged gears.
[0016]

That is, as drive means for rotating the folding blade shaft 8 in the folding cylinder 3, power is once transmitted from the driving side 1a to the operation side 1b across the frames via the shaft of the saw cylinder 14 provided in parallel with the folding cylinder 3. It is necessary to drive after letting.
[0017]
Therefore, a gear group meshed with both the drive side and the operation side is provided, and two sets of oil chambers (reference numerals 55 and 56) filled with oil for protecting the gears must be provided. The chambers 55 and 56 require oil supply / drainage, and the oil chambers 55 and 56 require countermeasures against oil leakage, which is difficult to maintain and manage, and has a large installation space and poor space efficiency. is there.
[0018]

A sensor 67 for detecting the speed is provided, and the drive control device 62 controls the operation of the motor 12 based on the detection information of each of the sensors 60, 61, 67. In particular, the drive control device 62 controls the speed while matching the rotation phase of the folding cylinder 3 and the rotation phase of the arm 24.
[0029]
Therefore, in the present embodiment, the shaft 22 (drive shaft of the folding blade 17 system) basically rotates in the same phase as the folding cylinder 3, and the arms 24a and 24b are rotated in response to the rotation of the folding cylinder 3. It has become. As a result, the tip of the folding blade 17 provided on the folding blade shaft 8 takes a required locus as shown by a solid line in FIG.
[0030]
Incidentally, as described above, the drive control device 62 controls the speed while matching the rotational phase of the folding cylinder 3 and the rotational phase of the arm 24, and relatively finely adjusts the rotational phase. . This relative phase shift means that the tip of the folding blade 17 changes the position on the locus shown in FIG. 4 and the position of the crease near the center of the folding book 39 can be shifted. Means you can.

The position of the crease is corrected.
[0033]
In this embodiment (FIG. 1), the shaft 22 is driven to rotate through the toothed pulley 11, the toothed belt 13, and the toothed pulley 9 fixed from the motor 12 to the shaft end of the motor 12.

[0035]
In particular, since the motor 12 can freely adjust the rotational phase of the arms 24 a and 24 b and the blade 17 with respect to the rotational phase of the folding cylinder 3, the fold position of the folding book 39 can be adjusted freely.
In this way, the folding blade shaft 8 is directly driven by the motor 12 which is another rotational driving system provided independently of the folding cylinder 3 driving system via the shaft 22, so that The helical gear 40 and the helical gears 5 and 8 that have been provided are no longer necessary, and there is no need to provide the oil chamber 56 on the operation side, and no oil supply / drainage treatment, measures against oil leakage, etc. are required, and the assembly and maintenance of the device can be performed. There is an advantage that becomes easier. This also has the effect of reducing the required floor area and improving space efficiency.
