BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll base paper supply device installed in a corrugator supply unit or the like.

[0002]

2. Description of the Related Art A mill roll stand for supplying roll base paper generally comprises a pair of left and right support arms. The support arms are rotatably supported at their base ends by a rotary drive shaft provided in the mill roll stand. The distance between the pair of support arms can also be adjusted by moving the left and right support arms toward and away from each other along a reverse screw provided on the rotary drive shaft. The roll base paper is clamped by the support arm, and is fed to a corrugator machine or the like while being lifted to a predetermined height position.

[0003]

By the way, in corrugator machines and the like, in recent years, the trend of small lot multi-product production has been increasing in response to various demands of customers, and as the average lot length is shortened, the roll changing work of base paper is performed. Becomes frequent,
The burden on workers is extremely heavy, and it is a bottleneck for labor saving. However, the conventional mill roll stand described above lowers the rolling center at the tip of the supporting arm to the center of the roll base paper placed on the floor in order to hold the roll base paper, and when the rolling center almost coincides with the center of the roll base paper, the left and right supports are supported. Since the roll base paper is clamped by bringing the arms close to each other and then lifted to a predetermined height position, it takes time to set the roll base paper at the predetermined position.

Further, since the roll base paper placed on the floor is placed at an approximate position in sight, an operator manually adjusts the position and orientation of the roll base paper so that the rolling center coincides with the center of the roll base paper. Center alignment is performed while performing. Therefore, there is a problem that it takes a lot of time and labor to set the optimum state and automation cannot be performed because these operations cannot be omitted.

The present invention has been made in view of the above problems of the conventional mill roll stand, and is a conveyor for supplying roll base paper to a pair of mill roll stands having a rolling center provided at a predetermined height position. It is an object of the present invention to provide a roll base paper supply device capable of accurately supplying and discharging a roll base paper in a short time by rationalizing all operations of supply, positioning, height position adjustment and discharge of the roll base paper by disposing the roll base paper. And

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a pair of left and right mill roll stands that hold a roll base paper between rolling centers provided at a predetermined height position so that they can come in contact with and separate from each other. A conveyor for transferring the roll base paper is placed between the mill roll stands, and this conveyor runs on a running track and sends the roll base paper between the mill roll stands and a discharge traverser for discharging the roll base paper between the mill roll stands. Consists of a pair of
Each traverser receives the roll base paper sent on the table that can be raised and lowered via the table lifter on the moving carriage,
That is, the roll raw paper supply device is provided with a transfer conveyor for discharging.

[0007]

The roll base paper supply device of the present invention constructed as described above supplies and discharges the roll base paper very smoothly and accurately in a short time. Note that the roll base paper is supplied to and discharged from the supply device by another conveyor. When the roll base paper is sent from another conveyor for supply, the slat conveyor of the supply traverser at the standby position is driven to receive the roll base paper. At this time, it is assumed that the discharge traverser is in an empty state and stands by at the mounting position on the mill roll stand. When the roll base paper, which is mounted on the mill roll stand and supplies the base paper to the corrugator machine, etc., supplies the base paper for a specified length and changes to a lot, drives the table lifter with the slat conveyor of the discharge traverser to discharge. Raise to a height position that matches the diameter of the roll base paper in the state.

When the roll of the residual base paper is received by the slat conveyor, the mill roll stands are separated from each other and the slat conveyor is lowered to separate the residual base paper from the mill roll stand. After that, both traversers are moved to stop the supply traverser at the mounting position and the discharge traverser at the discharge position. The new base paper of the supply traverser is lifted by adjusting the drive by the table lifter to a height position where the roll diameter center matches the rolling center, and when the centers match, the mill roll stands are brought closer to each other to hold the new base paper. On the other hand, in the meantime, the remaining raw paper is discharged from the discharge traverser by the slat conveyor, and when the new raw paper is mounted and the remaining raw paper is discharged, the two traversers become empty and the supply traverser is discharged. While lowering the slat conveyor, return both traversers to their original standby positions. In this way, the supply of the next new base paper and the discharge of the remaining base paper are repeated. Since the roll diameters of the new base paper and the residual base paper can be easily measured by a detector based on the optical signal, the rising position of the slat conveyor by the table lifter can be adjusted in advance based on the measurement results, and therefore the center of each roll diameter can be accurately set to the rolling center. Can be matched to.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a main cross-sectional view of the roll base paper supply device of the embodiment. The roll base paper supply device includes a pair of left and right mill roll stands 1, 1. Each mill roll stand 1 has a rolling center 2 for holding the roll base paper W at one end, is movable on a rail 3, and is driven by a rod 5 of a cylinder 4. The roll base paper supply device further includes a conveyor 6 for supplying roll base paper between the pair of mill roll stands. This conveyor 6
2, the supply traverser 6a that travels on the traveling rail 7 and sends the roll base paper W between the mill roll stands 1 and 1, and the roll base paper W from between the mill roll stands.
Is composed of a pair of discharge traversers 6b. In the illustrated example, the conveyor 6 is installed in the pit 8.

Each of the pair of traversers 6a and 6b has basically the same structure, and a table 11 is provided on a carriage 9 movable on a traveling rail 7 so as to be vertically movable via a table lifter 10, A slat conveyor 12 is provided on it. The table lifter 10 is formed of a combination of a cylinder 10a and an X-shaped link lever 10b in the illustrated example, but any other type may be used as long as it has a function equivalent to this. The slat conveyor is an endless conveyor provided with a large number of slat plates 12a on the outer periphery, and the slat plate 12a has a slightly curved receiving surface at the center, and the bent surface adjusts the posture of the roll base paper W. The center of the roll base paper W is made parallel to the center lines of the left and right rolling centers 2.

Incidentally, the pair of traversers 6a, 6b.
Are integrally connected by a connecting member 13 as shown in FIG.
Both traversers are driven by a cylinder 14 provided at the center of the lower surface. Further, in FIG. 2, the traverser 6a is shown in a base paper receiving position, and the traverser 6b is shown in a mounting position on the mill roll stand 1. Although not shown, a discharge position is further provided on the right side of the drawing. There is. At the base paper receiving position and the discharge position, other conveyors for supplying and discharging the base paper are provided. FIG. 3 shows a state in which the traverser 6b has reached the remaining amount of the roll base paper W at the mounting position in order to eject the roll base paper W.

In the apparatus of the embodiment configured as described above, the roll base paper is supplied and discharged as follows. In the state of FIG. 4, the traverser 6a is at the base paper receiving position and the traverser 6b
Is stopped at the mounting position. The new roll base paper W sent from another conveyor A is placed on the traverser 6a and is on standby. It is assumed that the roll base paper W supplied to the corrugator machine or the like is approaching the end state in the mill roll stands 1 and 1. When the supply of the roll base paper W is completed, the remaining base paper is discharged, so that the traverser 6b drives the table lifter 10 to raise the slat conveyor 12 to a height matching the diameter of the remaining base paper and receive the remaining base paper as shown in FIG. . After that, the table lifter 10 is lowered, or when both traversers 6a and 6b are moved while being lowered, the state shown in FIG. 5 is obtained.

In this state, the traverser 6a is stopped at the mounting position and the traverser 6b is stopped at the discharging position. After that, the roll base paper W on the traverser 6a is placed on the table lifter 10
Is driven to raise it to a predetermined height, the mill roll stands 1, 1 are brought close to each other, and the roll base paper W is held. After holding the roll base paper W, the table lifter 10 is lowered. On the other hand, from the traverser 6b at the discharge position, the slat conveyor 12 is driven to send out the residual base paper W and transfer it to another conveyor B. After that, a pair of traversers 6a, 6b
Drives the cylinder 9 and is returned to its original position. Both traversers are empty during this movement. Immediately after returning to the original position, the new raw paper W for the next lot is fed to the traverser 6a and is in a standby state, and the traverser 6b is still waiting for the next operation. Thus, the work is performed within an extremely short time by repeating the above operation.

[0014]

As described in detail above, in the roll base paper feeding device of the present invention, a pair of traversers are arranged with respect to a pair of mill roll stands which are provided with a rolling center at a predetermined height position and can be separated from each other. Since the traverser has a structure in which the transfer conveyor is installed on a table that can be moved up and down on a moving carriage, the mill roll stand simply needs to be opened and closed, and the roll base paper is fed by the traverser so that it matches the rolling center. It is adjusted and thus the centering movement is accurate and takes a short time. In addition, the height adjustment of new base paper or remaining base paper can be easily performed only by raising and lowering the table, and therefore the operation principle can be surely mounted by three operations of the mill roll stand opening, the carriage movement, and the mill roll stand closing. Also, the total operation time is greatly shortened, automation can be easily supported, and labor can be saved.
