Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a seat position adjusting device for a brake stand in a corrugator machine, and in particular, aligns the positions of both single-faced cardboard sheets adhered by a double facer to a predetermined position. The present invention relates to a seat position adjusting device capable of ensuring a positional relationship.

"Conventional technology" Generally, a corrugator machine transports each single-sided corrugated cardboard sheet fed from two sets of single facers into an overhead bridge, and conveys the overhead bridge while bending it back in a meandering shape and feeding it into a brake stand. In the brake stand, a predetermined tension (tension) is applied to each single-sided corrugated cardboard sheet, and the single-sided corrugated cardboard sheet is conveyed to the double facer. It has become. As a brake stand disposed between the overhead bridge and the double facer, a brake stand described in Japanese Patent Publication No. 56-32098 is known. The brake stand described in this publication accommodates two partition airtight plates which move away from each other and approach each other in a suction box having a lower surface opening, and a suction chamber is provided between the partition airtight plates. Is provided with a perforated plate on its lower surface. Further, a guide plate projecting downward from the perforated plate is provided integrally with each of the partition airtight plates.
Each of the brake stands adjusts the space between the partition airtight plates so as to match the width of the single-sided corrugated cardboard sheet to be fed in, that is, adjusts the size of the suction chamber. The spacing between them is also adjusted to match the width of the single sided cardboard sheet. As a result, when the single-sided corrugated cardboard sheet is fed into the brake stand, the guide plate holds both ends of the single-sided corrugated cardboard sheet and sucks the entire width of the single-sided cardboard sheet into the perforated plate by suction from the suction chamber through the perforated plate. The braking force is applied by the suction force.

However, the single-faced corrugated cardboard sheet manufactured with each single facer is folded back and forth in a meandering shape without tension on the overhead bridge, and is retained for a predetermined time. Since each single-faced cardboard sheet is carried into the brake stand through the brake stand, it may be shifted from a preset position when the single-sided corrugated cardboard sheet is carried into the brake stand. The forced alignment by contact with the end of the corrugated cardboard sheet has caused various problems. Normally, the lower single-faced cardboard sheet is positioned relative to the upper single-faced cardboard sheet, but only the single-faced cardboard sheet on the side to be aligned is moved in the horizontal direction perpendicular to the transport direction. Since the positioning is performed by moving the guide plate, etc., the single-sided corrugated cardboard sheet moves to a portion other than the portion where the holes of the perforated plate are perforated, and a situation in which a sufficient suction holding force cannot be obtained occurs. There is.
In other words, the perforated plate has holes for suction only in the portion corresponding to the maximum paper width of the normally produced single-sided cardboard sheet, and when the single-sided cardboard sheet is misaligned from the hole position as described above, Not only is it not possible to obtain a sufficient attraction force, that is, a braking force, but it also causes an imbalance in the attraction force depending on the lateral position of the single-faced corrugated cardboard sheet, causing a meandering sheet to be conveyed. In addition, since the single-sided corrugated cardboard sheet is forcibly aligned with the guide plate as described above, it is a cause of occurrence of wrinkles, damage to the sheet, and the like.

In view of the above circumstances, the present invention considers that when aligning one single-sided cardboard sheet with one single-sided cardboard sheet, the other single-sided cardboard sheet is shifted from the hole position of the perforated plate for suction. It is an object of the present invention to provide a seat position adjusting device for a brake stand in a corrugator machine in which an imbalance is not generated in the overall suction force and a single-sided corrugated cardboard sheet is not damaged during alignment.

"Means and Actions for Solving the Problems" The present invention has been made to achieve the above object, and in a brake stand of a corrugator machine,
A pair of first sheet guides for guiding both side edges of one of the single-faced cardboard sheets, which are movable in a direction perpendicular to the sheet conveying direction to adjust the distance therebetween, are provided.

You will be guided by. On the other hand, the upper suction box 4 has the same configuration as the lower suction box 5 except that it does not move, that is, except that both ends of the suction box 4 are fixed to the brake stand frame 3.
It has the same configuration as the lower suction box 5.
In the upper suction box 4, the motor 25
Rotate the screw rods 47 and 48 to share the airtight plate 4
9, 50, thereby adjusting the length of the suction chamber 51 so as to match the paper width of the upper single-sided corrugated cardboard sheet 7; The distance between the guide plates 52, 53 for pressing and guiding is adjusted, and the position of the guide plates 52, 53, that is, the position of the airtight plates 49, 50, is the same as that of the lower suction box 5 Similarly, it is detected by the rotary encoder 54. On the lower surface of the suction box 4, a perforated plate 11 of the lower suction box 5 is provided.
A perforated plate 55 having the same configuration as that described above is attached.

In FIG. 1, reference numeral 56 denotes a guide roll on the discharge side from the brake stand.

Next, the operation of the seat position adjusting device of the brake stand in the corrugator machine having the above configuration will be described. As shown in FIG. 1, the single-faced corrugated cardboard sheets 6 and 7 are moved through the guide rolls 8 and 9 into the suction boxes 4 and 5. At this time, the guide plates 32, 33, 52, 53 of the suction boxes 4, 5 and the airtight plates 26, 27, 49, 50 are spaced apart from each other (the length of the suction chambers 28, 51). ) Is adjusted by driving the motor 25 so as to match the paper width of each single-sided cardboard sheet 6,7. Therefore, each single-sided cardboard sheet
6, 7 are suction forces between suction chambers 28, 51 regulated to the same length as the paper width through suction holes 10 of perforated plates 11, 55, that is, suction force adjustment between the double facer and the braking force. The tension set by the machine 31 is applied. However, on the upstream side of the brake stand 1, since the sheet is conveyed while being folded and retained on the overhead bridge without applying tension, the single-sided corrugated cardboard sheets 6, 7 are conveyed while being laterally shifted in a direction perpendicular to the conveying direction. May be done. As a result, the upper and lower single-sided corrugated cardboard sheets 6 and 7 may be shifted in the horizontal position orthogonal to the transport direction and may be carried into the subsequent double facer. Therefore, the entire lower suction box 5 is moved and the upper With reference to the single-sided cardboard sheet 7 carried into the suction box 4, the single-sided cardboard sheet 6 carried into the lower suction box 5 is aligned. In order to move the lower suction box 5 in a direction orthogonal to the conveying direction of the single-sided cardboard sheet 6,
The motor 42 is activated to drive the jack 41, thereby moving the traction table 40 in the pushing or pulling direction. When the suction box 5 is moved, the suction box 5 moves so as to protrude and retract into a through hole 3a protruding from the brake stand frame 3. Therefore, the guide plate 3 of the lower suction box 5
2, 33, the single-sided corrugated cardboard sheet 6 is moved while keeping both ends of the single-sided corrugated cardboard sheet 6 by the amount shifted laterally, and then the single-sided corrugated cardboard sheet carried into the upper suction box 4 with both ends pressed. 7 is gradually forcibly returned to align with 7. The single-sided corrugated cardboard sheet 6 on the side to be aligned moves the entire suction box 5, and thus is shifted from the perforated portion of the perforated plate 11 where the suction hole 10 is formed, and the end of the perforated plate 11 having no suction hole 10. Since there is no possibility that the single-sided corrugated cardboard sheet 6 is positioned, the tension applied to the single-sided corrugated cardboard sheet 6 does not become non-uniform. The sheet 6 is free from any damage such as edge loss or wrinkling, and careless cutting.

In the above embodiment, only the lower suction box 5 is made movable. However, the upper suction box 4 is made movable, or both the upper and lower suction boxes 4,
5 can also be moved. Furthermore, although the motor 25 is shared to rotate the screw rods 14, 15, 47, 48 of the suction boxes 4, 5, it is needless to say that the motors can be driven by different motors.

[Effects of the Invention] As described above, according to the seat position adjusting device of the brake stand in the corrugator machine according to the present invention, the braking force is applied to apply the tension while guiding the both side edges of the single-sided cardboard sheet with the pair of sheet guides. With one of the suction boxes moved, the entire suction box is moved in a direction perpendicular to the sheet conveying direction, and the other suction box is aligned with the single-sided cardboard sheet to which the braking force is applied. Compared to the case of forcibly positioning only the (guide plate), the single-sided corrugated cardboard sheet does not cause damage such as wrinkling or loss. Furthermore, the single-sided cardboard sheet is guided by the pair of sheet guides, and the suction box is moved sideways while suctioning the liner surface of the single-sided cardboard sheet. Since there is no need to change the position of the suction hole, stable tension control and reliable lateral movement are possible without causing imbalance in the operation of the suction force.
