2. Description of the Related Art A corrugated paper having a required pitch is imparted to a core paper, a corrugated corrugated top portion and a liner are glued and bonded to each other to produce a single-sided corrugated board sheet, and a back liner is attached to the single-sided corrugated board sheet. Corrugating machines configured to produce double-sided corrugated sheet are widespread. In this corrugating machine, a single facer for manufacturing a single-sided cardboard sheet and a double facer for bonding a back liner to the obtained single-sided cardboard sheet are used as important devices. Further, as a supplementary facility, a base paper supply device for supplying a web such as a core paper, a liner or a back liner (these webs are hereinafter referred to as “base paper”) to the single facer or the double facer is indispensable. The base paper is loaded into a base paper supply device in a state of a roll having a predetermined diameter (hereinafter, referred to as “base paper roll”) wound around a paper tube serving as a core, where the base paper is fed and supplied. In addition, with the change in the order of the corrugated cardboard sheet during manufacturing, the base paper roll is removed from the base paper supply device, placed on a carrying means such as a cart, and carried out to a predetermined storage location.

A so-called swing arm type mill roll stand shown in FIG. 11 is widely known as a conventional base paper supply device used in a corrugated machine. The mill roll stand 10 includes a pair of left and right swing arms 13, 1 spline-coupled to horizontal rotating shafts 11, 12, respectively.
The center blocks 16, 16 that can be inserted into both ends of the paper tube 15 of the base paper roll 14 are mounted opposite to each other at the end of each of the arms 13, 13. A loading / unloading path 17 for loading and unloading the stencil roll 14 is formed on the left and right factory premises across the mill roll stand 10. This loading / unloading route 1
Reference numeral 7 denotes a pit which is dug down to the factory site at a required depth and extends in parallel with the rotating shafts 11 and 12, and a bogie 18 is disposed in the pit so as to be able to run freely. The trolley 18 is provided with a table 19 on which the base paper roll 14 is placed.
And only this table 19 faces above the pit.

[0004] In this mill roll stand 10, the swing arm 1 on one side supported on the right rotation shaft 12 is provided.
In order to load the base paper roll 14 onto the rolls 3 and 13, the carriage 18 on which the base paper roll 14 is placed is loaded on the right side of the loading / unloading path 17.
Drive the carriage 18 to the swing arm 1
It is made to arrive below the rocking locus of 3,13. At this time, the two swing arms 13, 13 are separated from each other. In this state, the right rotation shaft 12 is rotated clockwise, and the center blocks 16, 16 and the paper tube 1 of the base paper roll 14 are rotated.
Stop at the position where 5 and the center are aligned.

Next, the swing arms 13, 13 are moved closer to each other, and the paper tubes 15 of the base paper roll 14 are pressed (chucked) by the center blocks 16, 16, and then the arms 13, 13 are moved. By rotating the base paper roll 14 counterclockwise upward, the base paper roll 14 is loaded (also referred to as “base paper hanging”). Further, another swing paper roll 14 is loaded on the other swing arms 13, 13 supported by the left rotary shaft 11 by performing the same work. Then, the base paper fed from the base paper roll 14 loaded on one of the swing arms 13, 13 is supplied to a required portion of a corrugating machine (not shown).

In the case where the base paper roll 14 loaded in the swing arms 13 and 13 is removed from the arm and returned to the warehouse, or replaced with a base paper roll 14 of another standard in accordance with an order change during operation of the line, The swing arms 13, 13 located above are swung downward to arrive directly above the carriage 18 waiting in the carry-in / out path 17. Then open both arms 13,13,
The chucking of the base paper roll 14 is released, and the base paper roll 14 is transferred to the table 19 of the carriage 18. The swing arms 13 and 13 swing upward again to separate the two arms from each other and wait for the next chucking of the base paper roll 14. After that, the carriage 18 carries the transferred base paper roll 14 and exits the loading / unloading path 17 toward a predetermined stockyard. When a new base paper roll 14 is subsequently loaded, the carriage 18 on which the base paper roll 14 is placed travels through the carry-in / carry-out path 17 and reaches below the swing locus of the swing arms 13, 13.
Then, in the order described above, both swing arms 13, 1
3, the base paper roll 14 is loaded.

[0007]

As described above, in a conventional mill roll stand type stencil feeder in which a stencil roll conveyance conveyor is provided outside the two swing arms as described above, After the base paper roll 14 is carried in, the swing arms 13 and 13 are tilted obliquely downward to center each of the center blocks 16 and 16 with the paper tube 15 of the base paper roll 14, and then both arms are moved. The sheet moves close to chucking the base paper roll 14. Next, the loading of the stencil roll 14 is completed by the two arms 13 and 13 rotating obliquely upward again.

In order to replace the base paper roll 14A which is being fed out while being held by both swing arms 13 and 13 with another new base paper roll 14B, both swing arms 13 and 13 are required.
Is tilted downward, and then the chucking to the base paper roll 14A is released. And the arm 13,1
After rotating the base paper roll 3 obliquely upward, the old base paper roll 14A is carried out. However, the arms 13 and 13 are required to stay at the position where they have been tilted obliquely upward until the transfer of the next new base paper roll 14B is completed. You have to wait for time. When a new roll of base paper 14B is carried in, the swing arms 13, 13 tilt obliquely downward, and the center block 1
The centers of the paper rolls 15 and 16 and the paper core 15 of the base paper roll 14B are aligned. After that, both arms 13 and 13 move close to each other to chuck the base paper roll 14B,
When the arms 13 and 13 are again rotated obliquely upward, a new base paper roll 14B is loaded.

As described above, in order to exchange the base paper roll, the swing arm is reciprocated, and the swing arm is required to be moved upward at the inclined position until the transfer of the old base paper roll and the transfer of the new base paper roll are completed. At present, a lot of time is lost in the stencil hanging work because of having to wait. However, in the corrugated board manufacturing industry that needs to respond to order changes accompanying frequent small-lot production as in the present situation, it is extremely important to shorten the cycle time when replacing the base paper rolls. The device did not fully meet the demand.

The mill roll stand 10 shown in FIG.
As shown in FIG. 2, it is arranged below a known splicer 30 for splicing base paper. The floor surface of the factory premises where the splicer 30 is installed and the mill roll stand 10 is installed is parallel to the rotating shafts 11 and 12 that respectively support the swing arms 13 and 13 (supply of the base paper). Direction perpendicular to the direction),
Three pits are drilled to the required depth. That is, a first pit 31 is formed at an intermediate position between the two rotating shafts 11 and 12 constituting the swing arm mechanisms 28 and 29 in the mill roll stand 10. Conveyor EX is stored and arranged. The first pit 31 and the stencil roll unloading conveyor EX extend from the intermediate position between the first swing arm mechanism 28 and the second swing arm mechanism 29 to the drive side of the corrugating machine. The used base paper roll 14 is transported to the stock yard SY via the yard.

The base paper roll carry-in conveyors IN ₁ and IN ₂ are operated opposite to the base paper roll carry-out conveyor EX with the mill roll stand 10 interposed therebetween, with the outer sides of the corresponding swing arm mechanisms 28 and 29 as starting points. Extending to the side. That in web feeding apparatus for carrying out the present invention is located intermediate the base paper roll carry-out conveyer EX is both pivot shafts 11 and 12, on the left side of the rotation shaft 11 is disposed material roll loading conveyor IN _1,
Further, on the right side of the rotating shaft 12, a conveyor roll I for carrying a base paper roll is provided.
N ₂ is arranged.

As shown in FIGS. 1 and 3, on the driving side of the corrugating machine, a conveyor 40 extending to a stock yard SY for storing the base paper rolls 14 is arranged so as to be orthogonal to the base paper roll discharge conveyor EX. Has been established. In the transport conveyor 40, a turntable 38 for changing the direction of a pallet 35 on which the base paper roll 14 is placed is disposed at a connection portion with the base paper roll unloading conveyor EX. Therefore, the used base paper roll 14 carried out by the carry-out conveyor EX is
, And are sequentially conveyed toward the stockyard SY. A stock conveyor SC, which is a conventionally known slat conveyor, is arranged on the operation side opposite to the base paper roll unloading conveyor EX in alignment with the unloading conveyor EX.

On the slat conveyor SC, various base paper rolls 14 corresponding to various orders are stocked. For example, the base paper roll 14 that has been generally used is carried out as it is toward the stockyard SY by the carry-out conveyor EX, but the base paper roll 14 of the standard that is frequently used is used.
In the above, the slat conveyor SC is carried out and stocked here. When using the interrupt, the base paper roll 14 is moved from the slat conveyor SC to the base paper supply conveyor, and the interrupt is performed here. When it is not necessary to stock, the slat conveyor SC is used as a conveyor that assists the first and second carry-in conveyors IN ₁ and IN ₂ that carry in new raw paper. In addition, by turning the stencil roll 14 carried out from the unloading conveyor EX by the turntable 38, the stencil roll 14 can be sent to another stencil supply device without being directed to the stockyard SY.

In this case, as described above, the swing arm 1
The turning angles of 3 and 13 are set so as to be able to turn to the left and right by 45 ° with respect to the perpendicular P, respectively, and any angle beyond that is not turnable. (It is technically possible to make the turning angle larger than this, but at this time, there is a constraint that the lateral width dimension of the mill roll stand 10 becomes proportionally large). Therefore, even if the swing arms 13 and 13 stop rotating at a position inclined by 45 ° with respect to the perpendicular P,
The center blocks 16 and 16 do not coincide with the center of the paper tube 15 of the base paper roll 14 placed on each of the carry-in conveyors IN ₁ and IN _2, so that chucking cannot be performed. Therefore, in this embodiment, each of the conveyors EX, IN ₁ ,
A lifter 34 (described later) is provided in the pit where IN ₂ is located, and the lifter 34 raises the base paper roll 14 by a required distance so that the paper tube 15 of the base paper roll 14 and the facing center of the swing arms 13, 13 are opposed to each other. Block 16,
It facilitates centering with 16. In this case,
A pallet 35 which can be separated from each conveyor EX, IN ₁ , IN ₂ in order to raise the base paper roll 14 from the conveyor.
It is necessary to intervene. Therefore, the conventional slat conveyor is at least a conveyor IN for loading the base paper roll 14.
_1, the IN ₂ is unavailable.

In the base paper supply device shown in FIG. 1, the carry-out conveyor EX for the base paper roll 14, the first base paper roll carry-in conveyor IN ₁ , and the second base paper roll carry-in conveyor I.
Each of the N ₂ has a structure in which a lifter 34 is provided. The conveyor EX for carrying out the base paper roll 14 used in the present embodiment, the first and second conveyors IN ₁ , I for carrying in the base paper roll 14.
N ₂ is a kind of a so-called free flow conveyor.
For example, a pair of endless roller chains 37 wound around a plurality of sprockets 36 are provided in parallel inside each of the above-mentioned pits 31, 32, 33, and can continuously circulate in a required direction. As described above, the pits 31, 32, and 33 extending from the operation side of the corrugating machine are covered with covers so as not to impede the traffic of workers, and the covers are provided with the pair of endless roller chains 37, 37. There are two grooves facing the area.

As shown in FIGS. 1 and 2, the pallet 35 has two valley-shaped inclined surfaces 35a, 35a on which the base paper roll 14 can be stably mounted. Projecting portions 35b, 35b that can be placed on the two roller chains 37, 37 are formed to project downward from the back surface of the roller chain.

As described above, each pallet 35 includes the carry-out conveyor EX, the first and second carry-in conveyors IN ₁ and IN _2.
The roller chains 37, 37 forming the respective conveyor drive systems are detachably mounted. And
In each of the pits 31, 32, and 33 formed in parallel with and adjacent to the mill roll stand 10, a pantograph-type lifter 34 is stored and arranged correspondingly. The lifter 34 is driven by a required drive source such as a hydraulic cylinder (not shown) to move up and down. For example, the lifter 34
Is driven upward, the pallet 35 placed on the roller chains 37, 37 and adjacent to the mill roll stand 10 is first contacted from below. And the pallet 3
5 is separated from the conveyor drive and raised by the required distance. When the drive source is reversely biased, the lifter 34 is lowered, the pallet 35 is again stably placed on the roller chains 37, 37 forming the conveyor drive system, and further lowered to a fixed position below and stopped. To do.

Next, a method of supplying a base paper according to the embodiment configured as described above will be described with reference to the operation explanatory diagrams shown in FIGS. 4 to 7 and the flowchart shown in FIG. First,
Each swing arm mechanism 28 of the mill roll stand 10,
No. 29 will be described from the preparation stage for loading the base paper rolls 14 respectively. In the following description of the operation, in order to clarify the belonging of the swing arms 13, 13 pivotally supported by the left and right first and second swing arm mechanisms 28, 29, the left first swing arm 13 will be referred to as "left arm". , And the second swing arm 13 on the right side is distinguished from the “right arm”.
Further, regarding the pallet 35 and the lifter 34, the members located on the left side first conveyor IN ₁ are
Indicated as "L pallet" and "L lifter", member located out conveyor EX located in the middle, the "M Palette" and indicated as "M lifter", the conveyor IN ₂ for the second input of the right The member located is
The designation is made separately from “R palette” and “R lifter”.

In the operation ready state, the head 30a and the head 30b of the splicer 30 are largely deployed left and right. The left arms 13, 13 provided on the first swing arm mechanism 28 on the left side are stopped above the carry-out conveyor EX with a tilting posture to the right as shown by a two-dot chain line in FIG. In addition, the second swing arm mechanism 29 on the right side
The right arms 13, 13 provided at the same position are also stopped with a posture tilted obliquely rightward. At this time, an empty M pallet 35 is located directly above the lifter 34 on the carry-out conveyor EX, but the first and second carry-in conveyors I
It is assumed that neither the L pallet 35 nor the R pallet 35 has arrived at the lifter installation position for N ₁ and IN ₂ . The pair of left and right arms 13, 13 are axially separated from each other to open the center blocks 16, 16.

Next, the L pallet 35 on which the first raw paper roll 14A is placed travels on the first carry-in conveyor IN ₁ and arrives at the left side of the first swing arm mechanism 28, and L
It stops right above the lifter 34 and waits for chucking. In this state, the hydraulic cylinder 25 provided on the first swing arm mechanism 28 is urged to rotate the left arms 13 and 13 in a counterclockwise direction, and the first carrying conveyor IN is tilted to the left in an inclined posture. Stop above ₁ Further, the L lifter 34 is lifted, and the paper tube 15 of the first base paper roll 14A placed on the L pallet 35 reaches the leading ends of the center blocks 16, 16. When the roll diameter is sufficiently large for the reason that the first base paper roll 14A is unused or the base paper is not consumed so much, the degree of rise of the L lifter 34 is also small.
Next, the hydraulic cylinders 23, 23 are urged synchronously, the left arms 13, 13 are brought close to each other, and chucking of the base paper roll 14A by the center blocks 16, 16 is performed.

[0029] Thus, while the left arm 13 is stopped at the first upper loading conveyor IN _1, energization of the hydraulic cylinder 25 provided on the second swing arm mechanism 29 of the right is made . Thereby, the second carrying-in conveyor IN
_The right arms 13, 13 that have stopped above ₂ rotate counterclockwise and temporarily stop above the carry-out conveyor EX with an oblique leftward tilting posture. Next, the R pallet 35 on which the second raw paper roll 14B is placed travels on the second carry-in conveyor IN ₂ , reaches the right side of the swing arm mechanism 29, and stops right above the R lifter 34 to be chucked. To wait. In this state, the second swing arm mechanism 29
Of the right arm 13, 1
3 is rotated in the clockwise direction, and stops at the second upper loading conveyor IN ₂ have tilting attitude of the obliquely rightward.

In this case, the diameter of the second base paper roll 14B decreases due to consumption of the base paper, and the right arms 13, 13
It is assumed that the chucking to the paper tube 15 is impossible only by the rotation of. In this case, the R lifter 3
4 to operate the R pallet 35 to the second base paper roll 14
The required distance is raised together with B, and the paper tube 15 of the base paper roll 14B and the center blocks 16, 16 of the right arms 13, 13 are aligned. After that, the hydraulic cylinders 23, 23 are synchronously biased, and the right arm 1
Center block 1 with 3 and 13 placed close to each other
The second base paper roll 14B is chucked by 6, 16 (see FIG. 4). Further, the leading end of the base paper of the first base paper roll 14A is set on the head 30a of the splicer 30,
Further, the leading end of the base paper of the second base paper roll 14B is connected to the head 30b.
Set to.

As described above, when the chucking of the first base paper roll 14A and the second base paper roll 14B is completed, the left arms 13, 13 holding the first base paper roll 14A are connected to the hydraulic cylinder 25 in reverse. Rotate clockwise by urging. Then, the left arm 13, 13 is tilted and stopped diagonally rightward so that the first base paper roll 14A is exposed above the carry-out conveyor EX (FIG. 5).

Since the pallet 35 is empty, the L pallet 35 is moved out of the position where the L lifter is provided. Further, as shown in FIG. 5, each head 30a, 30b of the splicer 30 is
Move closer to each other, and the first base paper roll 14A is spliced to the base paper, and the base paper is supplied to a paper consumption mechanism such as a single facer (not shown) of a corrugating machine. Incidentally, L lifter 34 to the first carry-in conveyor IN _1, where L pallet 35 mounted with the third material roll 14C to be used in the order of after next is traveling arrives, located on the left side of the first swing arm mechanism 28 Stop right above and wait for the next chucking.

Next, the first base paper roll 14A loaded and used in the left arms 13, 13 is removed from the left arm and returned to the stockyard SY, or the order is changed during the operation of the corrugating machine. A case where the second base paper roll 14B according to another standard is replaced will be described. First, the base paper fed from the first base paper roll 14A is cut in the splicer 30 and cut off from the head 30a.
The base paper of the base paper roll 14 </ b> B is spliced by the splicer 30. As a result, the base paper of the second base paper roll 14B is
It is supplied to the paper consumption mechanism of the corrugated machine. Immediately after this splicing, as shown in FIG. 6, the M lifter 34 disposed on the carry-out conveyor EX is raised to make the old base paper roll 14A (first base paper roll) whose diameter is reduced due to consumption of the base paper. Is supported by the M pallet 35. Then, by moving the left arms 13, 13 in the separating direction, the chucking of the old base paper roll 14A by the center blocks 16, 16 is released. In this state, the M lifter 3
4 descends again, and the old base paper roll 14A
Is carried out from the carry-out conveyor EX.

Next, the left arm 13, 13 to release the old web roll 14A (first material roll) has to wait stopped rotates counterclockwise, also arrive at the first carry-in conveyor IN ₁ of the left The third base paper roll 14C is raised to the chucking position by the operation of the L lifter 34 disposed below the standby position. Then, after aligning the paper core 15 of the third base paper roll 14C with the center blocks 16, 16, the left arms 13, 13 are moved closer to each other to chuck the third base paper roll 14C. Chucking after the end for the third sheet roll 14C, together with the L lifter 34 is lowered again, L pallet 35 is exited to the first carry-in conveyor IN ₁ of the next roll loading preparation. In addition, the third to be used next time
The leading end of the base paper roll 14C is set on the head 30a of the splicer 30, and waits for the next paper splicing. In addition,
The unloading conveyor EX by unloading the old base paper roll 14A
Is empty. Therefore, as shown in FIG. 7, the right arm 13, 13 loaded with the new base paper roll 14B (second base paper roll) that is supplying the base paper is rotated counterclockwise to carry out the carry-out from the second carry-in conveyor IN ₂ side. Switch to the conveyor EX side. As a result, the second carry-in conveyor IN ₂ is emptied, and another fourth base paper roll 14D to be used one after another is planned.
Is placed on the R pallet 35, and the second loading conveyor IN
Bring it to ₂ . The above-described operation is alternately repeated in the order of FIG. 5 → FIG. 6 → FIG. 7 → FIG.

As described above, according to the stencil feeding method of this embodiment, the total time required for removing the stencil roll currently in use from the swing arm and chucking the stencil roll for the next order is equal to the central time. It is only necessary to rotate 90 ° from the position of the carry-out conveyor EX to the position of each carry-in conveyor IN ₁ , IN ₂ . Accordingly, as shown in FIG. 12, in the conventional mill roll stand, the swing arm which has discharged the base paper roll on the same conveyor once retreats to the original position and then turns to receive a new base paper roll again. Although the operation required complicated operation, the time required for the operation can be significantly reduced. Moreover, the base paper roll 14 carried into the mill roll stand 10 from the operating side of the corrugating machine
Is conveyed to the driving side, so that a large number of base paper rolls 14 do not stay on either the operating side or the driving side, and there is also an advantage that the loading / unloading of the base paper rolls 14 can be performed smoothly. is there.

Further, the base paper roll conveyor that is located outside each of the swing arm mechanisms 28 and 29 and extends to the operation side is
It is configured to be used as the conveyors EX ₁ and EX ₂ for carrying out the base paper rolls, respectively. Therefore, the mill roll stand 1
0 from the drive side of the corrugating machine to the base paper roll 14
Is rolled out, and the used stencil roll 14 that has been used due to an order change or the like is carried out to the operation side via each of the carry-out conveyors EX ₁ and EX ₂ and is carried to the stock yard SY.

FIG. 10 shows still another modification of the layout pattern in the factory. That is, in the pattern shown in FIG. 10, both swing arm mechanisms 28,
The stencil roll transport conveyor located in the middle of 29 extends to the operation side, and this conveyor functions as a stencil roll unloading conveyor EX. Further, the raw paper roll transporting conveyors located outside the respective swing arm mechanisms 28 and 29 are extended to the drive side, and the respective conveyors function as the raw paper roll carry-in conveyors IN ₁ and IN ₂ . . Therefore, the base paper roll 14 is similar to the layout pattern shown in FIG.

As described above, according to the method of feeding a base paper according to the present invention, in order to load a base paper roll into an arm and discharge the base paper roll from the arm, the swing arm is moved in a required direction. Only the basic operation of rotating in the direction is sufficient. Therefore, in the conventional mill roll stand, in order to achieve the same purpose, it is necessary to reciprocally rotate the swing arm in both left and right directions, and the cycle time can be remarkably shortened. Also, a lifter is provided on the transport conveyor of the base paper roll, and when transferring the base paper roll to the arm, the lifter carrying the base paper roll is raised, and the swing arm is rotated close to the base paper roll, The cycle time can be further reduced. Moreover, since the configuration is simple as a whole, there is an advantage that maintenance and inspection are easy and the manufacturing cost is low.
