Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conveying device for conveying a roll original support to a mill stand of a corrugator machine for forming corrugated cardboard sheets.

[Conventional technology]

The above-mentioned corrugator machine has a single facer for forming an A flute, a single facer for forming a B flute, a single-sided corrugated board formed by each single facer, and a front liner to be attached to the single-sided corrugated board in the flow direction of the sheet. A triple bleed heater device for heating the paper is arranged, and mill stands are provided on both sides of the single facer and in the sheet carrying direction of the trifle bleed heater device.

The above-mentioned mill stand is equipped with a pair of support arms that can hold the roll base paper from both ends, and when the roll base paper supported by one support arm is unrolled (this is used for two sets of support arms between the other support arm). The roll base paper is transported and preparation work for base paper exchange is performed.

The supply of roll base paper to Milstan F″ζ is usually as follows:
It is carried out by a conveyor laid on the floor.

This conveyor is placed on both sides of the mill stand, and one roll of base paper that is fed by a forklift or the like is placed on the carry-in end of the conveyor, and the roll of base paper is transported by the conveyor to the position of the mill stand. That's what I do.

(Problems to be Solved by the Invention) Conventionally, there is only one conveyor for transporting roll base paper, which has the following disadvantages.

In other words, in the Full Gator machine, once a corrugated sheet of a predetermined length is formed, the loft is changed.
There is often a surplus on the roll base paper. At this point, when replacing the roll base paper, it is necessary to remove the remaining roll base paper from the mill stand and supply a new roll base paper to the mill stand.

If there is only one conveyor for supplying roll base paper as in the past, it becomes necessary to discharge the remaining roll base paper and supplying new roll base paper using the same conveyor, and furthermore, the remaining roll base paper is transferred to the base paper warehouse. After transporting the new roll of base paper to the mill stand, the next roll of base paper to be used could not be placed on the conveyor, so it took a lot of effort to replace the base paper. This has the disadvantage that it takes time.

In order to shorten the time required to replace the base paper, a forklift or the like must go right next to the mill stand, remove the remaining roll base paper, and then feed a new roll base paper onto the conveyor. In other words, forklifts and the like come and go in the vicinity of mill stands and single facers, which can obstruct the operator's work, create stress when crowded with operators, and worsen the working environment due to exhaust gas. There is this inconvenience.

In addition, replacement paper rolls are wrapped with packing bands or have their edges glued with tape, so it is necessary to unpack them and prepare for paper splicing, which is not possible with conventional equipment. In this case, it is not possible to completely unpack on the conveyor, and it is necessary to set the roll base paper on the mill stand and then use a relatively narrow space to unpack, which reduces work efficiency and Safety (there is a Koma group).

Therefore, the technical object of this invention is to solve the above-mentioned inconveniences and to improve the work environment by making it possible to change roll paper in a short time, efficiently and safely. .

[Comprehensive means to solve problems]

In order to solve the above-mentioned problems, the present invention includes a plurality of conveyors arranged in a straight line, which are arranged on the same side of the mill stand, and a supply device for one roll of base paper is arranged on the same side of the mill stand. An unpacking machine is installed in which a pair of parallel rollers placed on both sides of the conveyance path are moved up and down by an elevating device along the conveyance path of the upstream conveyor located at the top of the conveyor. 111! A remaining roll base paper transporting device is provided to transport the remaining roll base paper fed into the I end ζ in a direction perpendicular to the base paper supply direction, and the remaining roll base paper transferred by the transporting device is transferred in the direction of the roll base paper supply side. The configuration includes a remaining roll base paper discharge device that discharges the remaining roll base paper.

[Effect]

In the conveying device configured as described above, the mill stands A plurality of rolls of base paper are arranged on the remaining conveyors, excluding the conveyor located on the side of the machine, in the order of use.Then, the rolls of base paper that have been conveyed to the equipment position are moved up the transport path of the conveyor by the upward movement of a pair of rollers. Lift it up and unpack it,
The unpacked roll of base paper is placed on the conveyor by lowering the roll.

When replacing the roll base paper, the remaining roll base paper supported by the mill stand is rolled down onto a conveyor on the side of the mill stand, and the conveyor and the conveyor supporting the roll base paper after unpacking are moved in the same direction. The remaining roll base paper is discharged from the side of the mill stand, and the unpacked roll base paper is conveyed to the side of the mill stand, where the roll base paper is held from both ends by the support arms of the mill stand.

The discharge conveyor 115 stops.

The conveyance device shown in the embodiment has the above-described structure, and in order to supply the roll base paper to the mill stand 13, the roll base paper in the base paper warehouse is conveyed onto the turntable 30 by a forklift or the like.

Now, after placing the roll base paper S on the turntable 30, the turntable 30 is rotated by a switch operation by the operator, and after rotating at a set angle, a pair of blocks 39 and 39 that stop the roll base paper S from rolling are moved. When one side is lowered by the rotation of the eccentric cam 42, the roll base paper S rolls in the direction of the lowered block 39, and the roll base paper S is transferred to the first conveyor 21 of the first supply device 20 or the first conveyor 21 of the second supply device 20'. S can be supplied.

After supplying the roll base paper S, the block 39 in the lowered state is raised, and the turntable 30 is rotated in the opposite direction as described above to wait in a state where the next supply of the roll base paper S can be received.

In addition, in the case where the roll base paper S is supplied from the turntable 30 onto the first conveyor 21, the first conveyor 21
When the roll base paper S is placed on the turntable 30
does not rotate, and the first conveyor 21 (upper) roll base paper S
We are unable to supply the required amount.

When the rolled base paper S is supplied to the carry-in end of the first conveyor 21, the first conveyor 21 moves and conveys the rolled base paper S in response to a detection signal from the detector PH1. During the conveyance, the roll diameter detector PH2 determines whether the roll diameter is larger or smaller than the set value, and when the leading edge of the roll base paper S moves to the position of the detector PH3,
The first conveyor 21 stops.

At this time, if there is no rolled base paper S at the end of the carry-in side of the second conveyor 22, the first conveyor 21 and the second conveyor 22 move together to bring the roll base paper S to the end of the carry-in side of the second conveyor 22. is conveyed, and when the detector PH4 detects the roll base paper S, the second conveyor 22 stops after a certain period of time.

Therefore, there is no more roll base paper S on the first conveyor 21, and the next roll base paper S can be supplied to the first conveyor 21. It can be transported to the department and stopped.
