Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a driving device for a corrugated board processing machine such as a box making machine, and more particularly, a plurality of processing cylinders are simultaneously installed at the processing position of the corrugated board sheet. The present invention relates to a drive device including a phase adjusting device that can be positioned.

"Prior Art" A conventional processing machine for corrugated board sheets of this type is, as shown in FIG. 3, a paper feeding device for feeding corrugated paper sheets S stacked and stocked by a predetermined number one by one to a subsequent device. 1, a printing unit 2 or 3 for printing at a predetermined position on the corrugated cardboard sheet S, and a creaser slotter unit 4 for scoring or slotting at a predetermined position on the corrugated cardboard sheet (for the creaser in FIG. 3). The cylinder is omitted), and the carry-out conveyor 5 for carrying out the corrugated board sheet to the subsequent apparatus is detachably connected and operated. The units 1 to 5 can be increased or decreased in number by exchanging with other types of processing units according to processing conditions. For example, as shown in FIG. 4, three printing units 2 and 3 are connected in series in order to increase the printing color, or only one is used when performing monochromatic printing. Even in the creaser slotter unit 4, it may be necessary to use not only one slot cylinder but also one equipped with a second slot cylinder, a so-called double slotter, depending on processing conditions. In each of the units 1 to 5, a driving gear 7 connected to a motor (not shown) drives a kicker 10 that kicks out the corrugated board sheet S via idle gears 8 and 9. Further, idle gear 11 to
The driven gears 14 and 15 are meshed with the driven gear 7 via the idle gears 11 to 13 via the driven gear 7 and the driven gear 22 with the idle gears 16 to 20 and the unit connecting gear 21 appropriately interposed therebetween. -24 mesh in sequence. The follower gears 25 to 27 are meshed with the driven gears 22 to 24, and the feed gears 28 to 37 are meshed with the idle gears 16 to 20. The driven gears 15 and 22 rotate the printing cylinders 38 and 39 shown in FIG. 3, and the driven gear 14 and the follower gear 25 rotate the press rolls 40 and 41. The driven gears 23 and 24 and the follower gears 26 and 27 are paired with the anvil cylinder to rotate the first slot cylinder 42 and the second slot cylinder 43 each having a working blade. The feed gears 28 to 37 are adapted to rotate the feed rolls 44 to 53 which feed out the corrugated board sheet S. The idle gear 20 is further meshed with a driven gear (not shown) to rotate the machining cylinder of the die cut unit.

As shown in FIG. 5, the driven gears 22 to 24 are provided with phase adjusting devices 54 to 56, respectively. Needless to say, the driven gear 15 also has a phase adjusting device (not shown). The phase adjusters 54 to 56, in a state in which the units 1 to 5 are combined, print the printing cylinders 38 and 39 as processing cylinders at predetermined printing positions of the corrugated cardboard sheet S and positions to be processed in the slots. The machining blades of the first slot cylinder 42 and the second slot cylinder 43 can be individually positioned.

On the other hand, in this type of processing machine, it may be sufficient to position a plurality of processing cylinders at the same time, and in order to satisfy such a demand, a drive device as shown in FIGS. 6 and 7 is known. That is, the driving device shown in FIG. 6 is the same as that shown in FIG. 5 until the driven gear 22 of the printing cylinder 39 is engaged with the driven gear 23 of the first slot cylinder 42 through the idle gear 18. A driven gear 57 is separately provided on the rotary shaft of the first slot cylinder 42, and the driven gear 57 is engaged with the driven gear 24 of the second slot cylinder 43 via the idle gear 19. Others are the same as those shown in FIGS. 4 and 5. When the phase adjusting device 55 is driven, the driven gear 57, the idle gear 19,
The second slot cylinder 43 can be simultaneously rotated and positioned through the driven gear 24 and the phase adjusting device 56.
Of course, if the phase adjusting device 56 is driven, only the second slot cylinder 43 can be rotated and positioned. Further, in the drive device shown in FIG. 7, a driven gear 58 is provided at a position opposite to the position having the phase adjusting device 55 of the rotary shaft of the first slot cylinder 42, and the driven gear 58 is provided.
The driven gear 60 is meshed with the idle gear 59, and the phase adjusting device 56 is attached to the driven gear 60. Then, if the phase adjusting device 54 is driven, not only the first slot cylinder 42, but also the second gear 58, the idle gear 59, the driven gear 60, and the phase adjusting device 56 are used.
The slot cylinder 56 can be rotated and positioned. During normal operation, in any of the driving devices shown in FIGS. 4 to 7, the rotational power from the driving gear 7 is obtained by the driven gears 22, 23, 24, 60, and the phase adjusting devices 54-56. The printing cylinder 39, the first slot cylinder 42, and the second slot cylinder 43 rotate at the rated speed via the. At this time, the phase adjusting devices 54 to 56 function only as a power transmission mechanism without driving the internal power motor.

[Problems to be Solved by the Invention] However, the drive device shown in FIGS. 6 and 7 has a first slot cylinder 42 and a second slot cylinder.
If 43 and 43 can be simultaneously rotated and positioned by one phase adjusting device 55, the driven gear 23 is provided with the phase adjusting device 55 coaxially with the rotation axis of the first slot cylinder 42. Since the first slot cylinder 42 is directly rotated for positioning, the phase adjusting device 55, especially the power motor in the phase adjusting device 55, which has a large torque and a large capacity, cannot be used. It is impossible to rotate the slot cylinder 42. Further, since the large driven gears 57, 78 having a large number of teeth are used to simultaneously rotate the second slot cylinder 43 together with the first slot cylinder 42, the number of parts is not increased. Needless to say, it is not easy to attach it to a drive device that does not have much space, and there is a problem that it causes an increase in size of the entire device and a rise in price.

Therefore, in view of the above circumstances, the present invention uses a small-diameter idle gear having a small number of teeth, so that not only a small-capacity and small-sized phase adjusting device can be used, but also the entire device does not become large, It is another object of the present invention to provide a drive unit for a corrugated board sheet processing machine, which is excellent in durability without being directly applied to the phase adjusting device during processing and which can position two or more processing cylinders at the same time.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is a group of driven gears in which an idle gear is interposed between a printing machine for printing a corrugated cardboard sheet and a processing cylinder such as a slotter for slot processing. In a driving device for a corrugated board sheet processing machine that is vertically connected to the driving part, a phase adjusting device is attached to an idle gear arranged closer to the power transmission driving part side than the appropriate number of processing cylinders, and the phase adjustment is performed. It is characterized by a driving device for a corrugated board sheet processing machine capable of simultaneously positioning a plurality of processing cylinders on the power transmission downstream side of the phase adjusting device by driving the device with a phase adjusting device motor.

[Operation] In the present invention, in the above means, it is possible to drive the phase adjusting device and sequentially rotate the plurality of processing cylinders on the downstream side of power transmission through the idle gear and the driven gear to perform positioning.

Further, since the number of teeth of the idle gear is smaller and the diameter thereof is smaller than that of the normally driven gear, the idle gear can be rotated by the phase adjusting device having a small capacity.

[Embodiment] An embodiment of the drive unit of the corrugated board sheet processing machine according to the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment, and the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals and will be described. In addition to the above-mentioned drive gear 7, idle gear 11
Through 13 and the driven gear 14, the driven gear 15 to which the phase adjusting device 61 is attached is meshed. The driven gear 15 is a phase adjusting device.
The printing cylinder 38 is rotated via 61. A driven gear 22 to which a phase adjusting device 54 is attached is meshed with the driven gear 15 via an idle gear 16. Driven gear 22
Is adapted to rotate the printing cylinder 39 via a phase adjustment device 54. Although not shown in FIG. 1, the driven gear 22 meshes with the idle gear 62 provided with the phase adjusting device 55 with the idle gear 17 and the unit connecting gear 21 interposed therebetween as in the conventional example. The idle gear 18 is provided on the output shaft of the phase adjuster 55. The idle gear 18 meshes with the driven gear 23 and the driven gear 24 provided with the phase adjusting device 56 via the idle gear 19. Driven gear
23 is adapted to rotate the first slot cylinder. The driven gear 24 is connected to the second gear via the phase adjusting device 56.
The slot cylinder 43 can be rotated. The driven gear 24 can be appropriately meshed with a downstream device such as a die-cut unit via the idle gear 20. The idle gears 16 to 20 and 62 are driven gears 15 and 22 to
Compared with 24, the number of teeth is extremely small and the diameter is small, as in the past. The phase adjusters 54 to 56, 61 are not limited to the gear mechanism type which has been widely used in the past, and are disclosed in JP-A-60-3.
It can be used in any of the so-called harmonic drive mechanism (trade name) formats described in Japanese Patent No. 2664.

Then, when the first slot cylinder 42 and the second slot cylinder 43 are simultaneously rotated to position the processing blade with respect to the predetermined position of the corrugated board sheet S to be processed, the phase adjusting device 55 is used. Drive it. That is, if the power motor in the phase adjusting device 55 is driven by a predetermined amount, the idle gear 8 and the output shaft of the phase adjusting device 55 are driven.
Rotates, and the driven gear 23 also rotates to rotate the first slot cylinder 42. The rotation of the driven gear 23 causes the second slot cylinder 43 to rotate via the idle gear 19, the driven gear 24, and the phase adjusting device 56. Since the phase adjusting device 56 is not driven at all, it functions only as a power transmission mechanism for transmitting the rotation of the driven gear 24 to the second slot cylinder 43. In this way, the first slot cylinder 42 and the second slot cylinder 43 can be simultaneously rotated by a predetermined amount to position the processing blade with respect to the predetermined position of the corrugated board sheet S to be processed. . At this time,
The idle gear 62 is in a fixed state without rotating due to resistance force due to meshing with the driven gear 22 in the preceding stage. Further, the second slot cylinder 43 and other printing cylinders 38,
When only 39 is rotated and they are individually positioned, the phase adjusters 54, 56 and 61 are driven separately. Therefore, since the gear ratio of the idle gear 18 to the driven gear 23 is extremely small, the first slot cylinder 42 can be sufficiently rotated and positioned even if the phase adjusting device 55 has a small capacity. The impact at the time of machining the slot cylinder 42 is not directly applied to the phase adjusting device 55.

FIG. 2 shows a second embodiment, in which the driven gear 23 of the first embodiment is meshed with an idle gear 63 having a phase adjusting device 56 attached thereto, and the idle gear 19 is attached to the output shaft of the phase adjusting device 56.
Are provided, and other configurations are the same as those in the first embodiment. In order to rotate the first slot cylinder 42 and the second slot cylinder 43 by a predetermined amount in order to position them at the same time, the phase adjusting device 55 may be rotated to output the output shaft of the phase adjusting device 55 in the same manner as above. With Idol Gear 18
The first slot cylinder 42 rotates together with the driven gear 23. The driven gear 23 is driven by the idle gear 63, the phase adjusting device 56, and the idle gear 19 and the driven gear 24.
At the same time, the second slot cylinder 43 rotates. Also at this time, the phase adjusting device 56 functions only as a power transmission mechanism. In order to rotate only the second slot cylinder 43 by a predetermined amount so as to be positioned, the phase adjusting device 56 is driven and the idle gear 19 together with the output shaft of the phase adjusting device 56 is driven.
Then, the second slot cylinder 43 is rotated via the driven gear 24. Idle gear 63 is a driven gear
It does not rotate due to the resistance due to meshing with 23. Others are the same as those in the first embodiment.

In each of the above embodiments, each phase adjustment device is used during normal operation.
54 to 56 and 61 do not drive and only function as a power transmission mechanism. Therefore, from the driving gear 7 to the idle gears 11 to 13
The driven gears 14 and 15 rotate via the
The driven gears 22 to 24 are sequentially rotated by receiving power from 6 to 20, 62 and 63, whereby the printing cylinders 38 and 39, the first slot cylinder 42, and the second slot cylinder 43.
Performs rated operation.

In each of the above-described embodiments, the creasing cylinder for performing the ruled line processing is the printing cylinder 38 shown in FIGS. 1 and 2.
It is possible to insert the same mechanism as 39, driven gears 15 and 22, and phase adjusters 54 and 61 between the driven gear 22 and the idle gear 62 by the number of sets corresponding to the number of creaser cylinders required.

[Advantages of the Invention] As described above, according to the drive device for a corrugated board sheet processing machine according to the present invention, two or more processing cylinders can be simultaneously positioned at predetermined positions to be machined on the corrugated board sheet, as well as normal teeth. Since the phase adjusting device is attached using the small number and small diameter idle gear, it is possible to use a small capacity phase adjusting device, and it is not necessary to use a gear with a large number of teeth as in the conventional case, so downsizing can be achieved. It can be expected, and since the impact at the time of machining the machining cylinder is not directly applied to the phase adjusting device, it is excellent in durability and very useful.
