Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a folding machine for an offset rotary press. [Prior Art] Conventionally, a so-called offset rotary press folding machine (using a turn bar) slits a web, overlaps and folds each slit web (hereinafter referred to as a ribbon) using a turn bar. ) uses a correction roller to correct the position of the ribbon in the vertical direction (the direction in which the ribbon travels), and corrects the position in the horizontal direction (at right angles to the direction in which the ribbon travels). This is done using a turn bar. For example, if there are 6 correction rollers and 6 turn bars, 1 to 6
It was equipped with 1 to 6 operation switches and 1 to 6 motors. In other words, when one operating switch is operated, one corresponding motor is driven. [Problems to be Solved by the Invention] However, in the case of threading two or more ribbons, if the number of printed colors on each ribbon is different, it is not possible to change the order of the slit ribbons in the folding machine. Although various products can be made, the order of the signatures of the ribbon that becomes the product does not match the order of arrangement of the correction rollers and turn bars. For this reason, the operator must correct the ribbon's vertical position using a correction roller and the horizontal position using a turn bar. It was necessary to judge each time which position of the correction roller and which position of the turn bar. As a result, there were drawbacks such as increased erroneous operations, reduced workability, and a negative impact on product quality. The present invention has been made in view of these points,
An extremely highly efficient folding machine for offset rotary presses that allows you to always operate the operating means according to the order of the ribbon by selecting the order of signatures and the positions of the correction roller and turn bar in advance when threading the ribbon. It provides: [Means for Solving the Problems] In order to achieve the above object, the present invention includes a slitter that divides the web into a plurality of ribbons, and a slitter that is provided corresponding to each ribbon and that corrects the longitudinal position of each ribbon. a plurality of correction rollers that are capable of adjusting the position of each of the correction rollers and the turn bars in the right direction and a plurality of turn bars that are provided corresponding to each of the ribbons and that are capable of correcting the positions of the respective ribbons in the lateral direction; A plurality of correction drive motors for moving the ribbons in the left direction, and a drive order of the correction drive motors can be selected according to the order in which the ribbons are stacked, and a signal is output in accordance with the selection. means, a plurality of operating means for different directions, which are capable of specifying each of the correction drive motors according to the selection order of the selection means, and output signals correspondingly; and signals from each of the operating means. The present invention is characterized by comprising a correction roller control means and a turn bar control means for giving a drive command to each of the correction drive motors only when signals from each of the selection means are present. [Function] According to the folding machine for an offset rotary press according to the present invention, when the turn bar control means and the correction roller control means operate the rightward operating means or the leftward operating means of the turn bar and the correction roller, the folding machine always generates a signature. Since it is possible to drive the turn bar or correction roller of the ribbon in the folding machine in the order corresponding to the stacking order of the ribbons forming the folding machine, there is no need to check the ribbon path in the folding machine, which greatly improves work efficiency.

This can be done by operating 6. Below, to simplify the explanation, turn bar 8...
13 will be explained, and the correction roller 14...1 will be explained.
9 is the same as this, so the explanation will be omitted. The types of signatures 23 produced by the folding machine main body 1 (the order in which divided ribbons A...F are stacked) are as follows:
It is determined by how the webs 2 and 3 are fed into the folding machine main body 1. Therefore, once the type of signature 23 to be produced is determined, the method of supplying the webs 2 and 3 to the folding machine main body 1 is determined, and the divided ribbons A...F are determined.
The order of passing through the turn bars 8 . . . 13 is determined, for example, as shown by solid line arrows and broken line arrows in FIG. 2a. In this case, the order of the ribbons on signature 23 is ABCFED from the top. Therefore, the horizontal position of the first ribbon A of the signature 23 is corrected by moving the first turn bar 8 (the vertical position is corrected by the first correction roller 14) left and right. The horizontal position of the fourth ribbon F of the signature 23 is corrected by moving the sixth turn bar 13 left and right. In other words, the horizontal position correction of the first to sixth ribbons A, B, C, F, E, and D of the signature 23 is performed by the first turn bar 8, the second turn bar 9, the third turn bar 10, 6th turn bar 1
3. Fifth turn bar 12, fourth turn bar 1
Turn bars 8...13 turn ribbons A, B,
Since they correspond to C, F, E, and D, the corresponding turn bars 8...13 are used. Therefore, before driving the offset rotary press, the turn bars 8, 9, 10, 13, 1 corresponding to the order of the ribbons A, B, C, F, E, D of the signature 23 are set in advance.
2 and 11 are shown in FIG. 5 as selection switches 411...4
16 selection units 4111...4166. In other words, the first selection switch 411
The second selection section 4111 is set and electrically connected to the drive motor 24 of the first turn bar 8 . Hereinafter, similarly, the second selection switch 412 is connected to the drive motor 25 of the second turn bar 9, the third selection switch 413 is connected to the drive motor 26 of the third turn bar 10, and the fourth selection switch 414 is connected to the drive motor 26 of the third turn bar 10. The fifth selection switch 415 is connected to the drive motor 29 of the turn bar 13, the fifth selection switch 415 is connected to the drive motor 28 of the fifth turn bar 12, and the sixth selection switch 416 is connected to the drive motor 27 of the fourth turn bar 11. In this way, the ribbon A of the signature 23 ,
Turn the order of B, C, F, E, D on turn bar 8...13
This corresponds to the order in which the ribbons A...F are supplied. Next, for example, if you want to move the fourth ribbon F of the produced signature 23 in the right lateral direction, move the third ribbon F.
Press the fourth right-hand operation switch 64 of the turn bar control circuit 40 shown in the figure. When the right direction operation switch 64 is pressed, its input signal is supplied to six first AND circuits 88a...88f. However, among these first AND circuits 88a...88f, the one that operates is the sixth first AND circuit 88 which receives the input signal from the selection section 4146 of the selection switch 414 of the turn bar selection section 41 in FIG.
There is only f. Therefore, only the sixth first AND circuit 88f outputs an output signal, and the output signal is supplied to the sixth right series OR circuit 111. The OR circuit 111 is the first AND circuit 88f
When receiving the output signal of , the output of the OR circuit 111 is sent to the second AND circuit 123 and the right contact
is supplied to a drive motor 29 that drives the sixth turn bar 13. When the sixth turn bar 13 finishes moving rightward by the drive motor 29, the limit switch 141 is activated to stop the output to the second AND circuit 123. As a result, the second AND circuit 123 is in a stopped state, the drive motor 29 is stopped, and the correction of the position of the ribbon F in the right lateral direction by the turn bar 13 is completed. Thereafter, in the same manner, the right direction operation switches 61...6 are operated in the order corresponding to the order of the ribbons A...F of the signature 23.
6 or the left direction operating switches 71...76, the webs 2, 3 can be moved to a predetermined turn bar 8...1 without checking the path of the webs 2, 3 inside the folding machine body 1.
Signature 2 whose position has been corrected by moving 3
You can get 3. Figure 2b is an example in which the order of stacking the ribbons A...F of signature 23 is D, C, E, B, F, A; this case is also similar to Figure 2a. This is done by the turn bars 8...13. In addition, the selection switches 411...4 in FIGS. 5 and 6
16, 511...516 are used for turn bars and for correction rollers, a total of 12 pieces, but in the ribbon threading example shown in Fig. 2, turn bars 8...13 and correction rollers 14...19 are used in correspondence. . In such a case, select switches 411...416,511
...6 516 is enough. In other words, the selection switch signal (selection unit 4111...4166, 51
11...5166) may be supplied to the turn bar control circuit 40 and the correction roller control means 50 . However, in cases other than ribbon threading as shown in FIG. 2, for example, if the ribbon threading path includes passing through the first turn bar 8 and then passing through the second correction roller 15, it is natural that the turn bar selection section Both the circuits 41 and correction roller selection section 51 are required. In addition, selection switches 411 to 416, 511 to
As 516, for example, a pin board may be used. That is, by selectively inserting a pin into one of the selection sections 4111 to 4166 and 5111 to 5166 in FIGS. 5 and 6, a selected signal is generated. In addition, selection switches 411 to 416, 511 using selector switches
~516 is also acceptable. In this method, instead of selectively inserting the pins of the pin board described above, a selector switch is switched and the selected signal is obtained in the same way. Alternatively, selection switches 411 to 416 using punch cards may be used. In this method, a sensor is installed according to the item to be selected, and the sensor sends a signal only to the holed part of the punch card, which is similar to the signal using the pin board or punch card described above. . Of course, a selection switch using magnetic tape or paper tape may also be used. [Effects of the Invention] As explained above, the folding machine for an offset rotary press according to the present invention provides the following effects. That is, when the turn bar control means and the correction roller control means operate the right-hand or left-hand manipulating means of the turn bar and the correction roller in a predetermined order, the order corresponding to the stacking order of the ribbons forming the signature is always adjusted. Since the ribbon turn bar or correction roller in the folding machine can be driven, there is no need to check the ribbon path in the folding machine, which greatly improves work efficiency.
