Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a roll cutting machine for cutting a long roll such as roll paper into a predetermined size (product size),
More specifically, it relates to improvement of a roll catcher portion in such a roll cutting machine.

(Prior Art) Conventionally, roll paper for toilets or the like has a wide web in advance around a winding core for a predetermined length (for example, 55 to 60 m).
The long roll formed by only winding is continuously cut by a roll cutting machine into product dimensions and manufactured.

This type of roll cutting machine used conventionally is
As shown in the figure, a roll feeding device 101 (detailed structure is omitted) for sequentially transporting the long roll P sequentially by product size, and cutting the long roll P transported by the roll feeding device 101. Rotary blade type cutting device for 102
And a roll catcher 107 provided before and after the cutting position on the transfer line where the long roll P is transferred.

The cutting device 102 has a disc blade 120 that revolves around the base shaft 100 (direction of arrow B) while rotating (direction of arrow A). Then, the long blade P is advanced by one pitch by the roll feeding device 101 while the disc blade 120 is turning upward,
When the disc blade 120 turns downward, the tip side of the long roll P is cut by the product size. still,
In this type of roll cutting machine, the long rolls P are transported in a two-row state in which the tip ends of the long rolls P, P can be simultaneously cut by one revolution of the disc blade 120. Has become.

The roll catchers 107 are provided one by one before and after the cutting position by the disc blade 120, and each include a roll receiving member 171 for receiving the roll from below and a roll pressing member 172 for pressing the roll from above. . Further, the roll receiving member 171 is divided into two parts on the left and right, and the respective divided roll receiving parts 171A and 171B are separated from each other by a space which allows passage of the pressing plate 114 of the roll feeding device 101. It is attached to 170. In this conventional example, the inner divided roll receiving portions 171B, 171B of the left and right roll catchers 107, 107 are integrated. Further, the roll pressing member 172 of each roll catcher 107, 107 is divided into two parts on the left and right (divided roll pressing part 172A,
172B) has been.

By the way, even for roll paper for toilets, for example, product rolls having different diameters are manufactured depending on the length of the wound web or the winding density.
When manufacturing product rolls with different diameters,
It is necessary to adjust the inner diameter of each roll catcher 107, 107 according to the diameter of the long roll P which is the basis thereof. However, in each roll catcher 107, 107 in the conventional roll cutting machine shown in FIG. Receiver 171A, 17
Split roll receiving parts 171A, 171A located outside of 1B
Is slidable in the left-right direction (the inner divided roll receiving portions 171B and 171B are fixed to the bed 170), and the divided roll pressing portions 172A and 172B are divided roll receiving portions 171 respectively.
It is slidable up and down on A, 171B, and by sliding the divided roll receiving portions 171A, 171A and the divided roll pressing portions 172A, 172B on the respective slide sides, the inner diameter of the roll catchers 107, 107 can be adjusted. I am trying. It should be noted that the divided roll receiving portions and the divided roll pressing portions on the slide side are fixed by bolts 179 after adjusting the positions.

(Problems to be solved by the invention) However, in the roll catchers 107, 107 in the conventional roll cutting machine shown in FIG. 7, in order to adjust the internal system, the divided roll receiving portions 171A, 171A and There is a problem that the split roll pressing portions 172A and 172B have to be adjusted individually and in a narrow working space, and the operation is troublesome and the adjustment requires a long time. Even for roll papers of the same standard, the roll diameter may vary in a minute range due to changes in web thickness, web tension, changes in web winding speed, etc., during the production of long rolls. (For example, the outer diameter of the roll may increase or decrease within the range of 1 to 2 mm). As described above, when cutting a long roll having the same standard with a variation in diameter with a roll cutting machine, the roll retainer members 172A and 172B of the roll catcher are fixed by the bolts 179 as in the conventional example shown in FIG. In the fixed state, there is a difference between the inner diameter of the roll catcher 107 and the outer diameter of the long roll P. When the outer diameter of the long roll is larger than the inner diameter of the roll catcher, the frictional force between the inner surface of the roll catcher and the outer surface of the long roll becomes large when the long roll is moved in the roll catcher. It may not be possible to move the long roll smoothly and the web of the roll surface may be torn or damaged.On the other hand, if the outer diameter of the long roll is smaller than the inner diameter of the roll catcher, the roll catcher will However, there was a problem in that it could not be held (in this case, the cut surface of the roll to be cut was not clean).

In view of the above-mentioned conventional problems, the present invention makes it possible to easily adjust the inner diameter of the roll catcher according to the diameter of the long roll to be cut, and there is some variation in the outer diameter of the long roll. Even in the case of the same standard (the outer diameter may vary during manufacturing even with the same standard), the roll catcher can always exhibit good holding force for long rolls with different outer diameter. The purpose is to provide a cutting machine.

(Means for Solving the Problem) The present invention has a pressing plate that presses the rear end surface of a long roll, and the long plate is intermittently transferred by a predetermined pitch to the lower side in the feeding direction by the pressing plate. A roll feeding device as obtained, a disc blade positioned above a transfer line for a long roll transported by the roll feeding device, a blade rotating device for rotating the disc blade, and the disc blade for the transfer line. A blade vertical drive device for vertically moving between a lower cutting position where the long roll transported above is completely cut and an upper retracted position where the long roll can pass below the disc blade; A roll receiving member for receiving the long roll from below at a position in the front-rear direction near the cutting position by the disc blade on the long roll transfer line and a roll for pressing the long roll from above. In a roll cutting machine provided with a roll catcher having a pressing member, the roll receiving member of the roll catcher has a pair of divided roll receiving portions which are divided into two parts on the left and right, and between the divided roll receiving portions. The divided roll receiving parts are close to each other with an interval allowing passage of the pressing plate.
It is installed so that it can be displaced in the separating direction, and by operating a single operating part on the pair of split roll receiving portions, the pair of split roll receiving portions are simultaneously displaced toward and away from each other. An interval adjusting mechanism configured so as to be able to be pressed is linked, and the roll pressing member constantly presses the upper surface of the long roll with an urging force that allows the movement of the long roll by an urging mechanism having a spring. The feature is that it is installed in a closed state.

(Operation) According to the roll cutting machine of the present invention, the long rolls to be cut are intermittently transferred at a predetermined pitch by the roll feeding device, and the disc blade is moved by the blade rotating device above the long roll transfer line. It can be rotated. This disc blade is moved up and down by a blade up-and-down drive device, and when the disc blade is moved downward, the tip side of the long roll on the transfer line is cut and while the disc blade is retracted upward, the roll is rolled. The long roll is advanced by one pitch by the feeding device. The long rolls transferred on the transfer line are held at a predetermined pressure by the roll catchers before and after the cutting position by the disc blade so that the long rolls do not move during cutting.

By the way, when cutting long rolls having different diameters with this roll cutting machine, it is necessary to adjust the inner diameter of the roll catcher portion according to the diameter of the long roll to be cut. The roll receiving member is divided into left and right parts, and each of the divided roll receiving parts can be displaced in the approaching / separating direction from each other by a space adjusting mechanism, and a single operating part is operated. This makes it possible to adjust the distance between the divided roll receiving portions.

On the other hand, in this type of long roll, even if it is a long roll of the same standard, there may be some variation in diameter at the manufacturing stage, but in the roll catcher of this roll cutting machine, the roll pressing member, Since the upper surface of the long roll is constantly pressed with an appropriate biasing force by the biasing mechanism having the spring, even when the long roll having a diameter variation is supplied to the roll catcher portion. The difference in the roll diameter can be absorbed by the biasing force of the spring. That is, when the diameter of the long roll is larger than the normal diameter (within the range of variation at the time of manufacturing), the roll pressing member is pushed up by the outer surface of the long roll against the biasing force of the biasing mechanism. On the other hand, when the diameter of the long roll is smaller than the normal diameter (within the range of variation at the time of manufacture), the roll pressing member is pushed down until it comes into pressure contact with the outer surface of the roll, and the roll diameter is different. Even long rolls can always be held with an appropriate holding force by the roll catcher.

(Effect of the invention) Therefore, according to the roll cutting machine of the present invention, when cutting long rolls having different diameters, by operating a single operation section of the gap adjusting mechanism, the left and right split rolls of the roll catcher are operated. Displace the receiving part in the approaching / separating direction at the same time,
The inner diameter of the roll catcher can be adjusted according to the diameter of the long roll to be cut, and the inner diameter adjusting operation of the roll catcher can be performed easily and in a short time.

Further, according to the roll cutting machine of the present invention, since the roll pressing member of the roll catcher is biased to the upper surface of the long roll by the biasing mechanism having the spring, the diameter slightly different from the normal diameter (at the time of manufacturing) Even when a long roll (within the range of variation) is supplied to the roll catcher portion, the roll pressing member always presses the roll upper surface with an appropriate biasing force. Therefore, for example, even when the diameter of the long roll is slightly larger than the normal diameter (within the range of variations at the time of manufacturing), the inner surface of the roll catcher does not excessively press against the outer surface of the long roll. Even if the roll movement is not hindered or the roll surface is not damaged, on the other hand, even if the diameter of the long roll is slightly smaller than the normal diameter (within the range of variation at the time of manufacture), the long roll There is an effect that the roll catcher can securely hold.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 6.

It is set. For example, if the diameter of the long roll P to be cut is about 11 cm, the vertical stroke of the disc blade 20 is set to about 15 cm. or,
The eccentric mechanisms 50, 50 on each side are set so that the phases of the eccentric bosses 51, 51 are in the same position with each other, so that the disc blades 20, 20 move up and down in synchronization with each other during operation. I have to.

In the index unit 45 portion, the blade up-and-down drive devices 4 and 4 have the disc blade 20 in the upper retracted position when the roll feeding device 1 is operating (when the long roll P is being transported forward), and The operation timing is set so that the roll cutting action (the disc blade 20 reciprocates up and down once from the upper retracted position) is performed by the disc blade 20 when stopped. That is, each of the blade up-and-down drive devices 4 and 4 operates to intermittently reciprocate the disk blades 20 and 20 up and down, but while the disk blades 20 are in the upper retracted position (the time required for one step is The roll feed device 1 operates to move the long roll P forward by one pitch during 1/4 of the time (it is stopped at the upper retracted position), and by the disc blade 20 while the long roll P is stopped. The cutting action is performed, and the timing is set so that this operation is continuously performed.

In this embodiment, as the blade up-and-down drive device 4, a disk blade 20 is used which reciprocates up and down in a substantially linear direction, but in other embodiments, as shown in FIG. 7, for example. It is possible to adopt a type (a type that has been generally used from the past) adapted to revolve a disc blade that revolves around a base axis.

Similarly, the male screw members 78A, 78A are simultaneously rotated in the screwing direction. When the male screw members 78A, 78A are rotated in the screw-in direction, the entire length of the connecting member 78 is shortened, and the left and right split roll receiving portions 71A, 71B are attached to the pivot shaft 7 at the lower end thereof.
When the divided roll receiving portions 71A and 71B are displaced from each other with respect to 3, 73 as the center to separate the divided roll receiving portions 71A and 71B from each other, and conversely, when the male screw members 78A and 78B are rotated in the screwing direction, the connecting member 78 The overall length is increased so that the divided roll receiving portions 71A and 71B can be brought close to each other as shown by chain lines 71A 'and 71B' in FIG. As described above, according to the gap adjusting mechanism 8, the left and right split roll receiving portions 71A and 71B can be simultaneously displaced in the approaching / separating directions by operating the single handle 80. Each split roll receiving part 71A,
The inner diameter between 71B can be adjusted by one-touch operation.

In addition, the interval adjusting mechanism 8 includes each of the divided roll receiving portions 71A,
A lock mechanism 90 is provided for prohibiting the turning operation of the handle 80 with the 71B set in a predetermined position. The lock mechanism 90 has a support plate 91 with a split groove 92 through which a horizontally long shaft 74 is inserted, and a pressing member (handle) 93 for compressing the gap between the split grooves 92 of the support plate 91. Support plate 91 is bed 70
It is bolted to the side of. The locking mechanism 90 allows the horizontal shaft 74 to rotate when the pressing member 93 is loosened (operates the handle 80), and conversely when the pressing member 93 is tightened, the space between the split grooves 92 is compressed. The horizontal axis 74 is locked.

The divided roll pressing portions 72A and 72B of the roll pressing member 72 are divided into the divided roll receiving portions 71 on the respective sides via the arms 81 and 81, respectively.
It is connected to A and 71B. That is, each arm 81, 81 has its upper and lower intermediate portions pivotally attached to the female screw member 78B of the connecting member 78 and the upper portion of the split roll receiving portion (71A, 71B).
The divided roll pressing portions 72A and 72B are pivotally attached to the upper ends of the arms 81 and 81, respectively. Arm 81 and split roll retainer (72A, 72
An angle adjusting member 89 consisting of a bolt and a nut for adjusting the angle of the split roll pressing portion is provided between the split roll pressing portion (B) and B), and the split roll pressing portion (72A, 72B) has an arc on its inner surface. The surface can be positioned so as to follow the outer surface of the long roll P which is inserted into the roll catcher. Further, as shown in FIG. 6, in particular, a urging mechanism for pressing the divided roll pressing portions (72A, 72B) to the outer surface of the long roll P at a position below the intermediate pivot portion (the reference numeral 79 portion) in the arm 81. 83 is provided. This biasing mechanism 83
It has a rod 84 laterally and outwardly attached to the outer surface of the split roll receiving portions (71A, 71B), and a spring 85 attached to the outer periphery of the rod 84. This spring
85 urges the lower part of the arm 81 outward so that the divided roll pressing portions (72A, 72B) are always urged to the outer surface of the long roll P. The urging force of the split roll pressing portions (72A, 72B) by the spring 85 has an appropriate pressure against the outer surface of the long roll P in which the inner surface of the split roll pressing portion is inserted into the roll catcher. It is set so that it can touch. That is, in a state in which the outer surface of the long roll P is pressed by the divided roll pressing portions (72A, 72B), the long roll P held by the roll catcher when the roll feeding device 1 is driven is rolled by the roll catcher. The long roll P can be held so as not to move during cutting. The outer end of the rod 84 of the biasing mechanism 83 is a hole formed in the lower end of the arm 81.
It penetrates 86 and projects outward. Further, a stopper 87 is provided on the outward protruding portion of the rod 84 to prevent the lower end portion of the arm 81 from being urged outward more than necessary. still,
The lower end of the arm 81 cannot swing outward from the state of abutting against the stopper 87, but can freely displace inward against the biasing force of the spring 85 (each divided roll). The pressing portion can escape outward as shown by the chain lines 72A 'and 72B' in FIG. 6). Also, this stopper
The position of 87 can be adjusted by a nut 87a.

The divided roll pressing portions 72A and 72B are adapted to be displaced inward and outward when the divided roll receiving portions 71A and 71B are swung inward and outward, and the divided roll pressing portions 72A are also moved. , 72B are urged toward the outer surface side of the long roll P by the spring 85. Therefore, when adjusting the interval between the divided roll receiving portions 71A, 71B only in a minute range, the divided roll holders are pressed. Even if the parts 72A and 72B are not specially adjusted, the long roll P can be maintained in the proper position and posture.

By the way, this type of long roll P may have a different roll diameter, although it is in a very small range, due to a change in web tension, a change in web winding speed, or the like in the manufacturing stage even if it is of the same kind (for example, it is manufactured. The outer diameter of the long roll may vary within the range of 1 to 2 mm). In this way, when the long roll P having a variation in roll diameter is supplied to the roll catchers 7A and 7B, if the roll pressing member is fixed with bolts as in the conventional example of FIG. 7, for example. When the length of the long roll P is larger than the normal diameter, the frictional force between the outer surface of the long roll and the inner surface of the roll catcher becomes excessively large, which makes it difficult for the long roll to move smoothly and rolls. The surface may be torn or damaged, and if the long roll P has a smaller diameter than the normal diameter, the long roll cannot be sufficiently held by the roll catcher. However, according to the roll cutting machine of this embodiment, the roll pressing member 72 (divided roll pressing portions 72A, 72B) is provided with the urging mechanism 83 having the spring 85 so that the long roll P inserted into the roll catcher portion is Even if the long roll P to be cut has a diameter different from the normal diameter (within the range of variations at the time of manufacture), it is installed because the upper surface is pressed with an appropriate urging force. It can be absorbed by the urging force of the spring 85, and the long roll P can always be normally held even when the outer diameter of the long roll P is slightly larger or smaller than usual.
