Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base paper supply device for a corrugated machine, and more specifically, to a mill roll stand system in which base paper roll conveyors are provided outside two swing arms. The present invention relates to a base paper supply device capable of effectively shortening the cycle time required for loading and unloading a base paper roll as compared with the base paper supply device.

Prior art A double-sided corrugated board sheet is produced by giving a corrugated sheet of a required pitch to a core paper, manufacturing a single-sided corrugated board sheet by pasting and adhering the corrugated corrugated top portion and a liner, and then attaching a back liner to the single-sided corrugated board sheet. Corrugated machines configured to manufacture are widely used. 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 ancillary equipment, a base paper supply device for supplying a web of core paper, liner or other back liner (these webs are referred to as “base paper” hereinafter) to the single facer or the double facer is indispensable.

This raw paper is loaded in a raw paper supply device in a state of a roll (hereinafter referred to as “raw paper roll”) wound around a core paper tube, and the raw paper is fed out and fed there.
Also, with the change in the order of the corrugated cardboard sheet during manufacturing,
The stencil roll is detached from the stencil supply device, placed on a carrying means such as a trolley, and carried out to a predetermined storage location.

A so-called swing arm type mill roll stand shown in FIG. 6 has been widely known as a base paper supply device used in the corrugating machine. The mill roll stand 10 includes two pairs of left and right swing arms 13 and 13 which are spline-coupled to horizontal rotary shafts 11 and 12, and the ends of the roll paper tubes 15 can be inserted into the ends of the arms 13. Center blocks 16 are mounted opposite to each other.

In addition, a loading / unloading path 17 for loading and unloading the base paper roll 14 is formed on the left and right sides of the factory premises across the mill roll stand 10. This loading / unloading route 17
Is dug down to the surface of the factory site to the required depth.
It is composed of a pit extending in parallel with 11, 12 and a carriage 18 is movably arranged in the pit. The trolley 18 is provided with a table 19 for mounting the base paper roll 14 on its upper part, and only this table 19 is exposed above the pit.

In this mill roll stand 10, the right rotation shaft 12
In order to load the base paper roll 14 on the swing arm 13, 13 on one side supported by the
The trolley 18 is moved to the right-side loading / unloading path 17 to bring the trolley 18 below the swing locus of the swing arms 13, 13. At this time, the two swing arms 13, 13 are separated from each other, and in this state, the right rotation shaft 12 is rotated clockwise, so that the center blocks 16, 16 and the paper tube 15 of the base paper roll 14 are in contact with each other. Stop at the position where the centers of are aligned.

Next, the two swing arms 13, 13 are moved close to each other, and the center block 16, 16,
After pinching (chucking) the paper tube 15 of
The base paper roll 14 is loaded (also referred to as "base paper hook") by rotating the 3, 13 counterclockwise upward. In addition, the other swing arm 1 supported by the rotary shaft 11 on the left side
The same operation is performed on 3, 13 and another base paper roll 14 is loaded. 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).

The base paper roll 14 loaded on the swing arms 13
From the arm and return it to the warehouse or change the order while the line is in operation.
For example, the swing arms 13, 13 located above are swung downward, and the loading / unloading path 17 is replaced.
To arrive directly above the truck 18 waiting. Next, both arms 13 and 13 are released to release the chucking of the base paper roll 14 and the base paper roll 14 is moved to the table 19 of the carriage 18.
Reprinted to. Also, the swing arms 13 and 13 swing upward again to separate the two arms from each other, and
Wait for chucking 14 (see Figure 7). 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 continuously loaded, the carriage 18 on which the base paper roll 14 is placed travels through the carry-in / carry-out path 17 and arrives below the swing locus of the swing arms 13, 13. . Then, the base paper roll 14 is loaded on both the swing arms 13 in the order described above.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, in the conventional mill roll stand type base paper supply device in which the transport conveyors for the base paper rolls are provided outside the two swing arms, respectively, as described above, Both swing arms 1 after the raw paper roll 14 has been loaded
Tilt 3,13 diagonally downward, and move each center block 16,1
The center of the base paper roll 14 is aligned with the paper core 15 of the base paper roll 14, and then both arms move close to each other to perform chucking on the base paper roll 14. Then, the two arms 13, 13 are again rotated obliquely upward to complete the loading of the base paper roll 14.

Further, in order to replace the base paper roll 14A that is being fed and held by both swing arms 13 and 13 with another new base paper roll 14B, the base paper rolls 14 and 13 are tilted obliquely downward, and then tilted. Release chucking for 14A. After rotating the arms 13 and 13 diagonally upward, the old base paper roll 14A is carried out. However, the arms 13 and 13 are tilted diagonally upward until the transfer of the next new base paper roll 14B is completed. You have to wait for the required time in the posture you have just reached. When a new base paper roll 14B is carried in, the swing arms 13 and 13 tilt obliquely downward to center the center blocks 16 and 16 with the paper tube 15 of the base paper roll 14B. After that, both arms 13 and 13 move close to each other to chuck the base paper roll 14B, and both arms 13 and 13 rotate obliquely upward again to load a new base paper roll 14B.

As described above, in order to replace the base paper roll, the swing arm must be reciprocated, and the swing arm must wait in the upward tilt position for the required time until the unloading of the old base paper roll and the loading of the new base paper roll are completed. In fact, the fact is that a lot of time is lost in the work of applying the base paper. 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.

Operation of the base paper supply device according to the embodiment Next, regarding the operation of the base paper supply device according to the embodiment having the above-described configuration, the operation explanatory diagrams shown in FIGS. 4A to 4D and the flowchart shown in FIG. Will be described with reference to. First, the preparatory stage of loading the base paper rolls 14 into the carriers 31, 31 of the base paper hanging device 20 will be described.

In the following explanation of the action, the left and right carriers 31, 31
In order to clarify the affiliation of the arm support members 34, 34 and the chucking arms 35, 35 arranged on the left side, the left arm support member is the “left arm support member” and the left chucking arm is the “left chucking arm. The right arm support member is to be distinguished from the “right arm support member”, and the right chucking arm to be distinguished from the “right chucking arm”. Regarding the trolley 26, the trolley located on the left loading route IN ₁ is designated as “L trolley”, the trolley located at the middle loading route EX is designated as “M trolley”, and the right loading route is designated. The trolley located at IN ₂ shall be designated separately from the "R trolley."

The head 54 on the spliner 54 is
The a and the head 54b are greatly expanded left and right. The carrier 31 on the left is, as shown by the chain double-dashed line in FIG. 4 (a),
It is stopped above the unloading route EX. Also right carrier 31
Is stopped above the import path IN ₂ . Ejecting route E at this time
An empty M truck 26 arrives at X, but the loading route IN ₁ ,
It is assumed that neither L truck 26 nor R truck 26 has arrived at IN ₂ . The pair of left and right arm support members 34, 34 are arranged so that the cylinder 48 is connected to both piston rods 48a, 48a.
Are urged in the extending direction to separate them from each other and open the center blocks 16, 16 of the chucking arms 35, 35 arranged on the arm supporting members 34, 34. Further, each chucking arm 35 stands by at the most retracted position in the storage portion 50 of the arm support member 34.

Then, the L carriage 26 on which the base paper roll 14A is placed is loaded into the loading path I.
Drive N ₁ , stop at a predetermined position and wait for chucking. In this state, the hydraulic cylinders 41, 41 connected to the left carrier 31 are synchronously urged in the direction in which the piston rods 41a, 41a are pulled in, the left carrier 31 is moved leftward, and the loading path IN ₁ Stop at the top. Further, the left chucking arms 35, 35 are pushed down by urging the hydraulic cylinders 51, 51, and the tip ends of the center blocks 16, 16 are moved to the L carriage 2
The paper core 15 of the base paper roll 14A placed on 6 is reached.

If the roll diameter is sufficiently large for the reason that the base paper roll 14A is unused or the base paper is not consumed so much, the left chucking arm 35, 35
The descending degree of is also small. After that, the both rod type hydraulic cylinders 48 are urged in the direction in which the piston rods 48a, 48a are pulled in, the left arm supporting members 34, 34 are brought close to each other, and the base paper roll 14A by the center blocks 16, 16 is made. Chucking. Then, the left chucking arms 35, 35 are lifted to move the base paper roll 14A to the L carriage 26.
Away from the table 27.

As described above, while the left carrier 31 is stopped above the carry-in path IN ₁ , the hydraulic cylinders 41, 41 connected to the right carrier 31 are attached to the piston rods 41a, 41a in the extending direction. Momentum is made. As a result, the right carrier 31 that has stopped above the carry-in path IN ₂ moves to the left and temporarily stops above the carry-out path EX. Next, base paper roll 14B
The R carriage 26 on which is mounted travels along the carry-in path IN ₂ , stops at a predetermined position, and waits for chucking. In this state, the hydraulic cylinders 41, 41 are reversely biased to move the right carrier 31 to the right and stop it above the carry-in path IN ₂ .

In this case, as in the case described above, the right chucking arms 35, 35 are lowered so that the tips of the center blocks 16, 16 reach the paper tube 15 of the base paper roll 14B placed on the R carriage 26. After that, the double rod type hydraulic cylinder
48 is urged to bring the right arm supporting members 34, 34 close to each other, and the center block 16, 16 chucks the base paper roll 14B (see FIG. 4 (a)). Then, the left chucking arms 35, 35 are raised again, and the loading path IN ₂
Wait for the supply of base paper above.

Further, insert the end of the base paper roll 14A into the splicer 54
Of the base paper roll 14B is set on the head 54b.

As described above, when the chucking of the base paper roll 14A and the base paper roll 14B is completed,
Replace the left carrier 31 holding A with the hydraulic cylinders 41, 41.
Is synchronously urged to expose the base paper roll 14A above the carry-out path EX (see FIG. 4 (b)).

Therefore, the L carriage 26 on the left-hand loading path IN ₁ becomes empty, and the L carriage 26 is moved out of the chucking position. Further, as shown in FIG. 4 (b), the heads 54a and 54b of the splicer 54 move close to each other, and the base paper roll 14A is spliced to the base paper, so that the base paper is a single facer of the corrugating machine (Fig. (Not shown), etc. In addition, the L carriage 26 on which the base paper roll 14C used for the next and subsequent orders is placed travels to the carry-in path IN ₁ , stops at the chucking position, and waits for the next chucking.

Next, the base paper roll 14A which is loaded and used in the left carrier 31 is removed from the left carrier 31 and returned to the stockyard, or due to an order change that occurs during operation of the corrugating machine, the base paper according to another standard. The case where the roll 14B is replaced will be described.

First, the raw paper fed from the raw paper roll 14A is cut in the splicer 54 and cut off from the head 54a, and the raw paper of the raw paper roll 14B loaded in the right carrier 31 is spliced by the splicer 54. Thereby, the base paper of the base paper roll 14B is supplied to the paper consumption mechanism of the corrugating machine.

Immediately after this paper splicing, the left chucking arms 35, 35 are lowered to mount the old base paper roll 14A whose diameter has decreased due to the consumption of the base paper on the M carriage 26. Then, by moving the left arm support members 34, 34 in the separating direction, the chucking of the old base paper roll 14A by the center blocks 16, 16 is released. And the old base paper roll 14A is M truck 26
Along with that, it is carried out from the carry-out route EX. The left chucking arms 35, 35 are retracted into the storage portions 50, 50 of the left arm support members 34, 34 after releasing the chucking of the old base paper roll 14A.

Next, the left carrier 31 that has discharged the old base paper roll 14A moves to the left and stops and waits, and the left chucking arms 35 and 35 descend and the base paper that has arrived at the left-side loading path IN ₁ On the paper core 15 of the roll 14C, the center block 16,
After matching 16 with each other, the left arm support members 34, 34 are moved close to each other to chuck the base paper roll 14C (see FIG. 4 (c)). After chucking the base paper roll 14C, the chucking arm 3
5,35 rises again and stands by, and the L carriage 26 exits from this carry-in path IN ₁ to prepare for the next roll carry-in.

Also, the tip of the base paper roll 14C to be used next time is
It is set on the head 54a of the splicer 54 and waits for the next splice. The carry-out path EX is emptied by carrying out the old base paper roll 14A. Then, as shown in FIG. 4 (d), the right carrier 31 loaded with the new raw paper roll 14B being fed with the raw paper is moved leftward to switch from the carry-in path IN ₂ side to the carry-out path EX side. As a result, the carry-in path IN ₂ becomes empty, and another base paper roll 14D to be used one after another is placed on the R carriage 26 and carried into the carry-in path IN ₂ . The above-described operation is alternately repeated in the order of FIG. 4 (b) → FIG. 4 (c) → FIG. 4 (d) → FIG. 4 (b).

Thus, according to the base paper supply device according to the present embodiment,
The total time required to remove the base paper roll currently in use from the carrier and chuck the base paper roll for the next order is the carrier EX at the center of the carrier.
It is sufficient to move from the position of to the position of each of the loading routes IN ₁ and IN ₂ . Therefore, as shown in FIG. 6, in the conventional swing arm type mill roll stand, the swing arm that discharges the base paper roll on the same conveyor is
Although it takes a complicated labor to rotate to receive the new supply of the new paper roll again after the paper roll is once retracted to the original position, the time can be remarkably shortened as compared with this.

In the present embodiment, the center transport path is used as the carry-out path for the base paper roll, and the transport paths located on both sides thereof are respectively configured as carry-in paths for the base paper roll. Even if it is configured as a carry-out route,
Similarly, it is possible to reduce the cycle time required for replacing the base paper roll.

EFFECTS OF THE INVENTION As described above, according to the base paper supply device of the present invention, the transport paths for the three base paper rolls are provided in parallel at a predetermined distance, and two bases are provided above the three transport paths. Since the carrier of (1) is configured to be movable in the direction orthogonal to the conveying path, the carrier can be moved in a desired direction in order to load the base paper roll into the chucking arm and discharge the base paper roll from the chucking arm. It only needs to be moved in parallel to. Therefore, in the conventional swing arm type 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 is significantly shortened. Is. In addition, even if it becomes impossible to chuck the base paper roll due to the tilting and lowering of the swing arm of the conventional mill roll stand due to the progress of consumption of the base paper, it is possible to deal with it freely by lowering the chucking arm. You can Further, since the conveyor pit is three-dimensionally constructed above the site of the factory where it is dug, there is an advantage that the installation work can be simplified and the installation cost can be effectively reduced.
