[0004]
In the creaser slotter of such a corrugated cardboard sheet making machine, a creaser and a slotter knife are attached to a plurality of yokes provided in the machine width direction, respectively. Generally, five yoke bodies are arranged in the machine width direction. Since each of these yoke members is configured to be movable to a desired position in the machine width direction according to the order of the sheet to be produced, each yoke member is provided with a yoke member moving shaft. In addition, a rotation drive shaft that rotationally drives a creaser ring and a slotter knife attached to each yoke body is provided so as to fit therethrough. Further, in addition to the rotation drive shaft and the yoke body moving shaft, an elevating shaft for elevating each yoke body and the like also penetrate between the machine frames, and each yoke body is inserted. As described above, since the rotary drive shaft also has a role of supporting each yoke body, the rotary drive shaft has an extremely large diameter in order to obtain rigidity of the machine.
[0005]
FIG. 8 shows, for example, the configuration of the slotter in the above-described creaser and slotter. The slotter has a rotary drive shaft 137 rotatably supported between frames, and yoke bodies 136a, 136b, etc. are provided on the rotary drive shaft 137 so as to be slidable in the axial direction via a key member 141. Have been. Then, a shifter member 139 is engaged with a shifter engaging portion 140 provided on a slotter holder 128 to which a slotter knife 130 is attached from each yoke body 136 via a bracket 138, and the yoke body 136 is slid by a yoke body movement shaft 134. It is configured to be movable in the machine width direction via a moving body 135.
[0006]
[Problems to be solved by the invention]
In the slotter configured as described above, each yoke body moving shaft is driven by a driving device such as an electric motor (not shown) in order to position each slotter knife 130 and the like at a predetermined position associated with the production before producing the corrugated cardboard sheet. By rotating 134 and 142, the respective yoke bodies 136a and 136b are moved in the machine width direction via sliding moving bodies 135 and 143 screwed to the yoke body moving shafts 134 and 142, and positioned at the sheet production position. At this time, the slotter holders 128a and 128b to which the slotter knives 130a and 130b are attached slide on the rotary drive shaft 137 via brackets 138a and 138b and shifters 139a and 139b attached to the yoke bodies 136a and 136b. Since the shifter 139 enters the engagement portion 140 of the slotter holder 128 engaged with the shifter 139 and is in sliding contact with the rotating slotter holder 128, a material softer than the slotter holder 128 is used. I have. Generally, a metal material such as a gunmetal or a resin material is used. Therefore, the shifter 139 is easily worn, and the shifter 139 that is in sliding contact with the engaging portion 141 of the slotter holder 128 is worn, and the engaging portion 140 is apt to rattle. Further, since the slotter holder 128 to which the slotter knife 130 is attached slides on the rotary drive shaft 137 via the shifter 139, the slotter holder 128 cannot be positioned at an accurate position. There was a problem that the cut edge of the sheet could not be formed neatly.
[0007]
Further, since the slotter holder 128 slides on the rotary drive shaft 137 with the movement of the yoke body 136 via the shifter 139, the slotter holder 128 may be twisted with respect to the rotary drive shaft 137. In that case, if the rotation drive shaft 137 is rotated to rotate the slotter holder 128, the rotation of the slotter knife 130 will not be able to obtain a regular rotation, and in addition to the problem that accurate grooving cannot be performed, Since the slotter knife 130 and the lower slotter knife 129 do not engage with each other accurately, the slotter knife 130 may be damaged, vibration may occur, and mechanical trouble may occur. Further, since the rotary drive shaft 137 supports a plurality of yoke bodies, a considerable weight is applied to the rotary drive shaft 137, and the rotary drive shaft bends. The lower slotter knife 129 and the lower slotter knife 129 do not engage with each other accurately, which causes the slotter knife to be damaged, to cause vibration, and to cause mechanical trouble.
[0008]
Further, on the side of the lower slotter knives 129 and 132, a rotary drive shaft having an extremely large shaft diameter is present in the entire width of the machine immediately below the grooved portion, so that slot debris is obstructed by the rotary drive shaft and smoothly removed. In this case, slot waste stays in the rotary drive shaft, the yoke 137, and the like, causing clogging. The clogging caused by these slot wastes affects the sliding of the yoke body 136 and the rotation of the slotter knife holder 128, thereby increasing the mechanical load and causing mechanical failure. The present invention provides a machined member support device in a corrugated cardboard sheet making machine that solves the various problems described above.
[0009]

Therefore, the above-mentioned yoke body moving body 13 and engaging member 14 are provided with a plurality of yoke body moving bodies 13 and a plurality of engaging members 14 corresponding to the number of yoke bodies 12 provided in the creasing slotter 1, respectively.
[0012]
Here, the moving means of the lower yoke body 23 in the machine width direction will be described. One of the objects of the present invention is to remove slot dust generated in the slotter section. However, it is preferable that there is no component mounted or axle-mounted between mechanical flakes below the sheet transport line PL of the slotter 3. . In order to achieve this object, it is considered preferable that the lower yoke member 23 does not move independently in the machine width direction, but instead moves following the upper yoke member 12. Therefore, a connecting device 62 for connecting the upper yoke body 12 to a part of the lower yoke body 23 is provided. The connecting device 62 is preferably provided on each of the yoke bodies 12 and 23 on the upstream side and the downstream side in the sheet feeding direction.

[0013]
Next, configurations of the yoke bodies 12 and 23 of the creaser 2 and the slotter 3 will be described. Since the structure for attaching the first slotter to the yoke body is substantially the same for both the cleaner 2 and the slotter 3, the attachment of the first slotter to the yoke body will be described, and the upper slotters 35 and 48 and the lower slotter will be described. Since the same applies to 54 and 57, the configuration of the upper slotter 35 will be described. Furthermore, since the upper first slotter 35 and the upper second slotter 48 have the same configuration, only the upper first slotter 35 will be described here. FIG. 2 is a sectional view taken along the line AA in FIG. One end of a slotter holder support 41 for attaching the slotter holder 42 to the yoke body 12 is rotatably attached. Then, a slotter holder 42 to which a slotter knife 45 is attached is rotatably attached to the other end via a bearing 44.

The body meshes with the slotter holder rotation transmitting body 38 via the idle gear 36.
[0016]
Next, the upper creaser 24 and the lower creaser 31 are the same as the upper first first slotter 35, the upper second slotter 48, and the lower first slotters 54 and 57. A creaser ring 25a is provided via the member 26 and the like. The lower creaser 31 opposed to the upper creaser 24 also has a similar configuration in which the lower yoke 23 is provided with a lower creaser ring 25b via a creaser holder support 32 and the like. The rotation drive system of the lower cleaner 31 and the lower first slotter 54 and the second slotter 57 has a common drive system. That is, as described above, one of the objects of the present invention is to remove slot dust generated in the slotter portion, but the device is mounted or axle mounted between mechanical flakes below the sheet transport line PL of the slotter 3. It is preferable that there is nothing. In order to achieve this object, it is preferable that the lower first and second slotters 54 and 57 are not driven independently of each other, but are configured to have a common rotary drive with the rotary drive system of the lower creaser.

A rotation drive transmission body 34 is provided on each yoke body 12. Then, the lower cleaner 31 is rotationally driven via the rotational drive transmitting member 34, and the first intermediate rotational drive transmitting member 60 provided between the lower slotter 31 and the lower first slotter 54 causes the lower cleaner to rotate. The rotational driving force from the motor 31 is transmitted to the lower first slotter 54 to be rotationally driven. Further, the rotation driving force from the lower first slotter 54 is transmitted to the lower second slotter 57 by the second intermediate rotation drive transmission body 61 provided between the lower first slotter 54 and the lower second slotter 57. And rotate. With such a configuration, at least the lower first slotter 54 and the lower second slotter 57 have no components mounted or supported between the machine frames below the paper line, and the slotter waste generated in each slotter is not provided. Has the advantage that it can be removed smoothly, and since there are no components mounted or supported between the machine frames, there is no weight or the like associated with the lower yoke body and the like, so that there is no bending or the like.
[0017]
The operation of the processing member supporting device in the cardboard sheet box making machine according to the present invention in the above configuration will be described. During the production of the corrugated cardboard sheet, the upper yoke body 12 and the lower yoke body 23, which have been positioned at desired positions in advance, are moved upward by the upper creaser drive shaft 27 which receives rotational driving force from a driving device (not shown) via the drive transmission gear 28. The upper slotter drive shaft 37 rotates the upper first slotter 35 and the upper second slotter 48, respectively, and the lower drive shaft 33 rotates the lower cleaner 31 and the lower first slotter 54 and the lower second slotter 57, respectively. The fed sheet is subjected to desired crease processing by the creaser rings 25a and 25b, and then the upper first slotter knife 44, the lower first slotter knife 55, the upper second slotter knife 53, and the lower second slotter. The desired groove processing is performed by the knife 58. At this time, slot waste generated in the first slotter portion and the second slotter portion naturally falls downward, but as in the above-described configuration of the present invention, a lower slotter shaft having a large diameter in the machine width direction is provided on the lower slotter side. Since there is no shaft for positioning the lower yoke, etc., the slot waste generated in the slotter section falls below the machine without any interference, and is processed by a slot waste processing device (not shown). There is no stagnation in the lower yoke 23, 54, 57 or the like. Then, the production is completed for a preset number of production sheets, and the production is terminated.
[0018]
Subsequently, at the time of order change for producing the next order, first, in order to move the upper yoke body 12 and the lower yoke body 23 in the machine width direction, the upper yoke body 12 and the lower yoke body 23 are moved to FIGS. 3A and 3B. The connection is made by the connection device 62 as shown. In this connection, each of the yoke bodies 12, 23 arranged in the machine width direction connects. At this time, it is preferable that the upper slotter knives 44 and 53 enter the corresponding lower slotter knives 55 and 58 and move in the machine width direction in a state where the blades are inserted (in the art, they are called blade coincidences). Then, the yoke body moving body 13 corresponding to each yoke body 12 is rotated by a driving device (not shown) or the like, and the yoke body 12 is moved to the next production position via the engaging member 14 engaged with the yoke body moving body 13. To perform positioning. At this time, since the upper yoke body 12 and the lower yoke body 23 slide on the rigid upper stays 6, 7 and the lower stays 15, 16 via the sliding members 4, 5, respectively, accurate positioning is possible. At the same time, the slotter holder 42 to which the slotter knife 45 is attached is not configured to slide on the slotter drive shaft via the shifter with the movement of the yoke body as in the conventional case, and the slotter holder 42 is moved in the machine width direction. Since there is no member serving as a resistance, the member moves integrally with the upper yoke body 12, so that the positioning is accurate and the slotter holder 42 does not rattle due to the movement resistance.
[0019]
In this manner, the upper slotter knives 45 and 53 and the lower slotter knives 55 and 58, as well as the upper creaser ring 25a and the lower creaser ring 25b, are positioned at the processing positions of the next order by the movement of the upper yoke body 12 and the lower yoke body 23. At the same time, the upper slotter knives 45 and 53 are appropriately moved and positioned in the circumferential direction to the next order processing start position by an actuator (not shown). Then, in order to adjust the clearance in accordance with the next order sheet, the upper creaser ring 25a is moved up and down by the creaser elevating shaft 29 to make a desired clearance with the lower creaser ring 25b, and the upper portion is similarly moved by the slotter elevating shaft 46. The slotter knives 45, 53 are raised and lowered to the desired gaps with the corresponding lower slotter knives 55, 58, respectively. Subsequently, the connection of the connection device 62 that has connected the upper yoke body 12 and the lower yoke body 23 is released, and the positioning operation to the next order production position is completed to prepare for paper passing. It should be noted that, in addition to the above-described lifting / lowering means by the respective lifting / lowering shafts 29 and 46 of the creaser 24 and the slotters 35 and 48, the upper yoke body 12 is individually raised / lowered by using a driving motor or an actuator using a fluid medium. The upper yoke body 12 may be individually raised and lowered.

You may comprise. As another means, it may be configured to be able to move via a pinion on a rack mounted between the machine frames, and in any case, on a stay (not shown) mounted between the machine frames. If the yoke body 71 is configured to be movable on the yoke body moving body 73 via the engaging member 72 via the sliding portion, the object of the present invention can be achieved. The same applies to the moving means of the yoke body 84 in the machine width direction in the lower punching device 70. One of the objects of the present invention is to remove punching debris similarly to the removal of slot debris generated in the slotter portion. It is preferable that there is no component mounted or axle mounted between the machine flakes below the sheet transport line PL. In order to achieve this object, it is considered preferable that the lower yoke body 84 does not move independently in the machine width direction, but rather moves following the upper yoke body 71. Therefore, a connection device (not shown) similar to that shown in FIG.

FIG. 5 is a side view of a sheet conveying device using the creaser slotter supporting device of the present invention, and FIG. 6 is a sectional view taken along the line BB in FIG. The creasers 24, 31 and the first and second slotters 35, 54, 48, 57 are not different from the above-mentioned creasers and slotters. The upper sheet guide 105 supported by the upper yoke body 12 slightly above the sheet conveyance line and opposed to the sheet conveyance line, and slightly lower than the sheet conveyance line and opposed to the sheet conveyance line. The sheet guides 106 and 107 are supported by the lower yoke body 23 and provided between the lower creaser 31 and the lower first slotter 54 and between the first slotter 54 and the second slotter 57, respectively. Then, a plurality of guide rolls 91, 92, 93, 94, and 95, each of which is mounted on the upper yoke body 12, an upper sheet transport device drive shaft 96 into which the upper yoke body 12 is inserted, and the upper sheet transport device A belt pulley 96 a slidably provided on the drive shaft 96 and freely rotatable with respect to the upper yoke body 12 is provided. Then, while traveling on the sheet facing surface side of the sheet guide 105, the upper sheet conveying belt 97 is stretched around the guide rolls 91, 92, 93, 94, 95 and the belt pulley 96a. Similarly, a plurality of guide rolls 98, 99, 100, 101, and 102, each of which is mounted on the lower yoke body 23, a lower sheet conveying device drive shaft 103 into which the lower yoke body 23 is inserted, and the lower sheet A belt pulley 103 a slidably provided on the transport device drive shaft 103 and freely rotatable with respect to the lower yoke body 23 is provided. Then, while traveling on the sheet facing surface side of the sheet guides 106 and 107, the lower sheet conveying belt 104 is stretched around the guide rolls 98, 99, 100, 101 and 102 and the belt pulley 103a. At this time, it is preferable that the lower sheet conveying drive shaft 103 that drives the lower sheet conveying belt 104 is disposed upstream of the lower first slotter 54 in view of slot dust removal by the slotter. When the sheet is fed and processed by the creaser and the slotter in the sheet conveying apparatus having the above-described configuration, the upper sheet conveying apparatus driving shaft 96 is rotated by a driving device (not shown) to rotate the belt pulley 96a. As a result, the upper sheet conveying belt 97 rotates. Similarly, the lower sheet conveying device driving shaft 103 is rotated by a driving device (not shown) and the belt pulley 103a is rotated, whereby the upper sheet conveying belt 104 is rotated. Then, the sheet fed from the upstream printing unit or the like is nipped by the upper sheet conveying belt 97 and the lower sheet conveying belt 104, and is conveyed to the cleaners 24, 31 and the slotters 35, 54, 48, 57.

【The invention's effect】
According to the processing member supporting device in the corrugated cardboard sheet making machine of the present invention, since all the parts such as the slotter holder are structures attached to the yoke body, when moving in the machine width direction, the machine width is reduced. Since there is no sliding part with each axis, such as a shaft mounted in the direction, there is little vibration and smooth movement is possible, and in addition to accurate positioning, mechanical movement that will occur in the future by repeating movement No rattling occurs. In addition, since there is no sliding surface, there is no mechanical wear, and accurate positioning is possible.For example, since the upper slotter knife and the lower slotter knife can be engaged accurately, accurate grooving is performed. Can be performed, and the sharpness is good, so the cut is clean and the commercial value is also improved.
[0027]
Further, as described above, since there is little occurrence of vibration and no mechanical rattling occurs, there is no breakage of the slotter knife, no occurrence of vibration and no mechanical trouble, and there is no cause of failure. Furthermore, since the rotating drive shaft or the like does not support a plurality of yoke bodies, considerable weight is applied to the rotating drive shaft, and the rotating drive shaft bends, so that the upper slotter knife and the lower slotter knife are separated. The cause of breakage of the slotter knife, occurrence of vibration, and occurrence of mechanical trouble, which were caused by the lack of accurate engagement, have been eliminated.
[0028]
Furthermore, since the lower slotter side does not have a large-diameter drive shaft having the same diameter, the problem that the slot debris is blocked by the rotary drive shaft and can be removed smoothly is also solved, and the mechanical load is increased. And the cause of mechanical failure has disappeared. Since a large-diameter drive shaft or the like is not required and the mechanism can be configured with an extremely simple structure, there is an advantage that the machine manufacturing cost can be reduced and the economic effect can be improved.
