Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roll base paper supply device installed in a supply unit or the like of a corrugator.

[0002]

[Prior Art]

 A mill roll stand that supplies roll base paper generally includes a pair of left and right support arms. The support arms are rotatably supported at their base ends by a rotary drive shaft provided on the mill roll stand, and a pair of support arms are supported. The distance between the arms is also configured so that the left and right support arms can be moved toward and away from each other along the 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]

[Problems to be solved by the device]

 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 customer demands, and as the average lot length is shortened, base paper roll replacement work becomes more frequent, and the burden on workers is increased. It has become extremely large and has become a bottleneck for labor saving. However, the above-mentioned conventional mill roll stand lowers the rolling center at the tip of the support arm to the center of the roll base paper placed on the floor to hold the roll base paper, and when the rolling center almost coincides with the center of the roll base paper, Since the support arms of 1 are brought close to each other to hold the roll base paper and then lifted to a predetermined height position, it takes time to set the roll base paper at the predetermined position.

[0004] Furthermore, since the roll base paper placed on the floor is placed at an approximate position in sight, an operator manually positions and orients the roll base paper so that the rolling center coincides with the center of the roll base paper. Center adjustment is performed while adjusting. Therefore, there is a problem that it takes a lot of time and labor to set the optimum state, and these operations cannot be omitted so that automation cannot be performed.

The present invention has been made in view of the problems of the conventional mill roll stand, and supplies roll base paper to a pair of mill roll stands having a rolling center provided at a predetermined height position. Providing a roll base paper supply device that can supply and discharge roll base paper accurately and in a short time by arranging a conveyor and rationalizing all operations of supply, position determination, height position adjustment, and discharge of roll base paper. This is an issue.

[0006]

[Means for Solving the Problems]

 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 into contact with and separate from each other. This conveyor is composed of a pair of a traverser for feeding that feeds the roll base paper between the mill roll stands and a discharge traverser that discharges the roll base paper between the mill roll stands. The traverser is configured as a roll base paper supply device that is equipped with a slat conveyor that receives and discharges the roll base paper sent on a table that can be raised and lowered via a table lifter on a moving carriage.

[0007]

[Action]

 The roll base paper supply device of the present invention configured as described above supplies and discharges the roll base paper very smoothly and accurately in a short time. It should be noted that the roll base paper is supplied to and discharged from the supply device by another conveyor. When the roll base paper is fed 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, the discharge traverser is in an empty state and is waiting at the position where it is mounted 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 the specified length and changes to a lot, the table lifter with the slat conveyor of the discharge traverser is installed. Drive to ascend to a height position that matches the diameter of the roll base paper being ejected.

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 for the traverser for supply is lifted by adjusting the drive by the table lifter to a height position where the center of the roll diameter 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. To do. On the other hand, during the meantime, the remaining raw paper is discharged from the discharge traverser by the slat conveyor and transferred to another conveyor.When the above new raw paper is mounted and the remaining raw paper is discharged, both traversers become empty and the supply traverser Lower both slat conveyors and return both traversers to their original standby position. 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 with a detector based on optical signals, the rising position of the slat conveyor by the table lifter can be adjusted in advance based on the measurement results. Can be matched exactly.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a main cross-sectional view of the roll raw paper supply device of the embodiment. The roll raw 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 the roll base paper between the pair of mill roll stands. As shown in FIG. 2, the conveyor 6 travels on a traveling rail 7 and supplies a traverser 6a for feeding the roll raw paper W between the mill roll stands 1 and 1, and discharges the roll raw paper W from between the mill roll stands. It consists 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 configuration, 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. In the illustrated example, the table lifter 10 is formed by combining the cylinder 10a and the X-shaped link lever 10b, but any other type may be used as long as it has a function equivalent to this. The slat conveyor is an endless conveyor having a large number of slat plates 12a on its outer circumference. The slat plate 12a has a slightly curved receiving surface in the center thereof, 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.

The pair of traversers 6a and 6b are integrally connected by a connecting member 13 as shown in FIG. 2, and both traversers are driven by a cylinder 14 provided at the center of the lower surface thereof. Further, in FIG. 2, the traverser 6a is shown in the base paper receiving position, and the traverser 6b is shown in the mounting position on the mill roll stand 1. Although not shown, a discharge position is provided on the right side of the drawing. Has been. 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 stopped at the base paper receiving position, and the traverser 6b is stopped at the mounting position. On the traverser 6a, the new roll base paper W sent from another conveyor A is placed and waiting. In the mill roll stands 1 and 1, it is assumed that the roll base paper W supplied to the corrugator machine or the like is approaching the end state. When the supply of the roll base paper W is completed, the remaining base paper is discharged. Therefore, the traverser 6b drives the table lifter 10 to raise the slat conveyor 12 to a height corresponding to the diameter of the remaining base paper as shown in FIG. 3, and receives the remaining base paper. .. After that, if the traversers 6a and 6b move after the table lifter 10 is lowered or 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 driven to its predetermined height by driving the table lifter 10, and the mill roll stands 1 and 1 are brought close to each other to hold the roll base paper W. 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, the pair of traversers 6a and 6b drive the cylinder 9 to be returned to the original position. Both traversers are empty during this move. Immediately after returning to the original position, the new raw paper W for the next lot is fed into 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.
