Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention continuously folds web pieces used as, for example, tissue paper or towel paper into a zigzag shape to form a laminate.
The present invention relates to a quantitative web laminated body manufacturing method and apparatus for automatically separating a fixed amount of web laminated body from a subsequent folded web every time a predetermined number of the web pieces are folded.

[0002]

2. Description of the Related Art Folding webs such as boxed tissue papers and towel papers are generally formed by alternately folding two types of web pieces in a zigzag shape and stacking the web pieces on each side in a mutually meshed state. Manufactured.

As a web laminated body manufacturing apparatus of this type, those shown in FIGS. 1 to 8 have been conventionally known (for example, Japanese Patent Publication No. 5-81510). This known quantitative web laminated body manufacturing apparatus is, as shown in FIG. 1, web cutting apparatuses 102 and 102 for sequentially cutting two continuous webs W, W on the left and right, which are continuously fed, into predetermined lengths.
Web pieces WS, WS on each side cut by the web cutting device
Web folding device 104 that folds each other in a zigzag shape
And a predetermined number of web pieces WS, W by the web folding device.
After folding S, the quantitative web laminated body Y is separated from the following folded web by a web laminated body separating device 105.

The web folding device 104 includes a pair of left and right folding rolls 141 and 141 which also serve as a blade roll of the web cutting device 102, and a pair of left and right packer fingers (a depth in the drawing) for separating the folding web from the folding rolls 141. 147, 147). On the outer peripheral portion of the folding roll 141, concave grooves 142 having a predetermined length in the circumferential direction are formed at three positions at an angle of 120 °. Each of the concave grooves 142 is provided with a vise 149 (a plurality of vices are respectively divided in the depth direction of the drawing) for holding the folded portion of the web piece WS. And the packer fingers 147 on each side
When the recessed groove 142 is approaching, the tip of the packer finger protrudes into and out of the recessed groove 142, and the vice 149
The folded portions of the web pieces gripped by are alternately extruded below the folding roll 141, whereby the web pieces on each side are folded in a zigzag shape. Further, the folded webs folded by the web folding device 104 are sequentially stacked on the elevating table 150. still,
The lifting table 150 has a lifting drive device 152 as the web stack X formed on the lifting table 150 is deposited and increased.
A slight movement is made to drop.

The known quantitative web laminated body manufacturing apparatus carries out the following series of operations to successively produce the quantitative web laminated body Y in sequence. That is,
As shown in FIG. 1, continuous webs W and W of two left and right systems are cut into predetermined lengths by web cutting devices 102 and 102, respectively, and the cut web pieces WS and WS on each side are cut by a web folding device 104. The zigzags are folded on each other, and the folded webs are sequentially stacked on the elevating table 150. As shown in FIG. As shown in FIG. 3, the web laminated body separating device 105
The partition bar 171 is driven into the space between the folding webs that are subsequently folded on the web laminated body X, and immediately after that, the lifting table 150 is lowered to move the quantitative web laminated body on the lifting table 150 as shown in FIG. Y is separated from the subsequent folding web, and while it is descending (partition bar 17
(Below 1), the clamp finger 161 is operated (the horizontal hook at the upper end rotates horizontally by an angle of 90 °), and the clamp finger 161 is used to lift the lifting table 150.
While holding the upper edge of the upper surface, and further holding the upper edge of the quantitative web laminated body Y by the clamp fingers 161, as shown in FIGS.
7, the clamp fingers 161 are operated in the pressing release direction as shown in FIG. 7, and the quantitative web laminated body Y on the elevating table 150 is transferred onto the starting end portion of the conveyor 282. .

Further, immediately below the web folding device 104, the web pieces are continuously folded even during the work of discharging the quantitative web laminated body Y on the elevating table 150. The body X) is first supported by the partition bar 171 as shown in FIG. 5, and is re-supported from the middle by the temporary receiving table 119 as shown in FIG. Then, as shown in FIG. 8, the quantitative web laminated body Y on the lifting table 150 is transferred to the conveyor 282.
After being handed over to the side, the empty lifting table 150 rises, the web stack X on the temporary receiving table 119 is received by the lifting table 150, and the state shown in FIG. 1 is restored. Thus, the quantitative web laminated body Y is continuously manufactured. In the case where the fixed-quantity web laminated body Y manufactured in this way is manufactured in a long state, it is cut into product lengths and then stored in a paper box in a boxing process to be a final product.

In the known quantitative web laminated body manufacturing apparatus shown in FIGS. 1 to 8, the partition bar 171 is operated as follows. That is, as shown in FIG. 2, when a predetermined number of web pieces WS are folded on the elevating table 150, a detection device (for example, a counter that measures the number of rotations of the folding roll 141) first counts up and counts up. A signal is issued, and by the count-up signal, the telescopic cylinder 172 shown in FIG. Is rotated around the shaft 175, so that the partition bar 171 is driven into the gap between the folding web to be folded and the folding web below the folding web (see FIG. 3).

By the way, in the case of an insulating material such as paper, the web comes into contact with various devices such as air and rolls at the stage of manufacturing the raw paper or the step of processing the raw paper into a product (quantitative web laminate). Friction causes the folding webs to become charged with static electricity (especially this tendency becomes more pronounced in the dry climate of winter). It should be noted that it is known that the static electricity charged on this type of web is mixed with a portion where a large number of (+) polarity ions are collected and a portion where a large number of (−) polarity ions are collected even in one web piece WS. Has been. Then, in the process of manufacturing the quantitative web laminated body Y, if the web is charged with static electricity or if the web is newly charged with static electricity, the following problems occur.

That is, when static electricity is charged on the folding web folded on the lifting table 150, the static electricity tends to cause the web pieces to stick to each other. In particular, in the case of a thin web such as a tissue paper, for example, as shown in FIG. 9, the uppermost web folded piece W of the quantitative web laminated body Y is used.
When a potential difference is generated between S and the web located on the lower surface thereof, the web folding piece WS may stick to the web below it without being normally stretched. For example, in the upper and lower webs, when charged parts of the same polarity come close to each other, the webs repel each other, and when charged parts of opposite polarity come close to each other, they become attracted to each other. The web folding piece WS may be polymerized in a partially swollen state.

[0010]

However, in the quantitative web laminated body Y manufactured by the above-mentioned known quantitative web laminated body manufacturing apparatus, when the uppermost web piece WS is charged with static electricity, The upper web piece WS may stick to the web below it without being normally spread (the uppermost web piece WS folds when the air enters the lower surface of the uppermost web piece WS and is partially raised). The web piece WS does not polymerize cleanly and looks bad,
For example, as shown in FIG. 38, there is a problem that the web piece WS raised during the packaging may collide with the upper wall of the packaging box B. Further, as shown in FIG. 9, in the case of manufacturing a long fixed-quantity web laminated body Y for a plurality of products, as described above, the uppermost web folded piece WS is not spread neatly (for example, the uppermost portion). In the state where the web piece WS is wavy), the long quantitative web laminate is cut into the final product lengths (cutting line Yc). For example, as shown in FIG. In the extended state, there is a problem that the product value is lowered due to the inclination as shown by the reference numeral WSe or the step as shown by the reference numeral WSf.

In view of the above-mentioned conventional problems, the present invention removes static electricity from the web piece located at the uppermost portion of the quantitative web laminated body to thereby polymerize the uppermost web piece in a state where it is neatly spread. The present invention has been made for the purpose of providing a method for producing a quantitative web laminate and an apparatus for producing the same.

[0012]

The present invention has the following structural features as means for solving the above problems.

First, in the present invention (a method for producing a quantitative web laminate and an apparatus for producing the same), continuous webs of two lines which are respectively continuously fed out are sequentially cut by a web cutting device into webs each having a predetermined length, The web pieces on each side are sequentially folded alternately in a zigzag shape by a web folding device, and the folded webs are stacked on the lifting table in a state of being meshed with each other. Every time a predetermined number of web pieces are folded on the elevating table, the elevating table is lowered by the web stacking device to separate the quantitative web laminated body on the elevating table from the subsequent folding web, and further elevating and lowering. It is configured so that the quantitative web laminated body on the elevating table can be post-fed by the discharging device in a state where the table is lowered to the lowermost moving position.

Further, the quantitative web laminated body manufacturing apparatus of the present invention is provided with a static electricity removing device for removing static electricity charged on the web piece located at the top of the quantitative web laminated body to be manufactured. This static eliminator is an air blower that blows air to the web located at the top of the quantitative web stack on the lifting table when the lifting table is lowered (during start of descent or during descent) or at the lowest position. , An ion generator that generates air ions for static electricity removal that can remove static electricity charged on the web, and the air ions for static electricity removal generated by the ion generator in the air blown by an air blower device. I try to mix it in.

As the ion generator, for example, pulse D
It is preferable to use a method called the C system, which is capable of producing (+) polar ions and (−) polar ions in a mixed state. Then, the air ions for removing static electricity generated by this ion generator are sent into the supply pipe of the air blower through the adjusting valve, and the air containing the air ions is placed on the uppermost portion of the quantitative web laminated body on the lifting table. I try to spray it on a piece of web.

The blowing of the air mixed with the air ions for removing static electricity is carried out at the time of starting the lowering of the lifting table on which the quantitative web laminated body is placed, during the lowering of the lifting table, or at the most lowered state of the lifting table. It may be carried out at least at any time, but it can also be carried out continuously from the start of the descent of the lifting table to an appropriate time in the most lowered state.

[0017]

In the present invention (the apparatus for manufacturing a web laminated body and the apparatus for manufacturing the same), when a predetermined number of web pieces are folded on the elevating table, the elevating table is lowered to form a quantitative web laminated body on the elevating table. The subsequent folded web is separated, but at that time, when static electricity removing air ions (air ion mixed air) are blown to the web piece located at the top of the quantitative web laminate, the air ions are discharged to the top web. The surface of the web can be neutralized with the static electricity charged on the web, and the static electricity can be removed from the web. That is, on the web side, there are a mixture of a large number of (+)-polarized ions and a large number of (-)-polarized ions. Ions are mixed and the (-) polar ions in the blowout air are attracted to the (+) polar ion part on the web side, while the (+) polar ion part in the blowout air is attracted to the (-) polar ion part on the web side.
Polar ions are attracted to neutralize the bipolar static electricity charged on the web side.

When the static electricity is removed from the web (particularly, the uppermost folded web) in this manner, the web piece located at the top of the quantitative web laminate does not easily stick to the web on the lower surface side of the web. The upper web piece is naturally easy to spread.

[0019]

As described above, according to the present invention (equipment for producing a quantitative web laminate and its producing apparatus), static electricity can be removed from the produced quantitative web laminate (in particular, the uppermost folding web). Therefore, the web piece located at the uppermost portion of the quantitative web laminated body is unlikely to stick to the web on the lower surface side thereof, and the uppermost web piece can be spread neatly. When the uppermost web piece is spread neatly in this way, the folded state is good and the appearance is clean, and since there is no raised portion at the top of the quantitative web laminated body, there is an effect that the box packing work can be performed smoothly. is there. In addition, for example, even when a long quantitative web laminated body for a plurality of products is manufactured and the long quantitative web laminated body is cut into final product lengths later, the uppermost web piece is spread neatly. In this case, the cut end of the uppermost web piece can be cut in a straight line, and the web piece can be accurately formed into a quadrangle in the stretched state (the appearance does not deteriorate).

The pushing bar WSc is for sharply revealing the folding line WSc 'as shown in FIG. 39 when the web piece WS is folded in two at the web folding portion. The pushing bar WSc is adjusted by adjusting the attachment depth of the elastic material 26 on the anvil roll 23 side where the convex strips 32 on the transfer roll 31 side come into contact, or by changing the hardness of the elastic material 26. The strength (sharpness) can be adjusted.

The web folding device 4 has a pair of left and right folding rolls 41, 41. On the outer peripheral surface of each folding roll 41, as shown in FIGS. 15 to 17, at predetermined intervals (for example, 70 to 8) in the roll axial direction.
A large number of annular grooves 42, 42, ... Are formed at intervals of 0 mm. The width of each annular groove 42 is about 29 mm,
The depth is about 40 mm. Further, the tip end of the packer finger 47 and the tip end of a presser bar 61 (or partition bar 71) described later are respectively projected and retracted in the respective annular grooves 42, 42 ... And the upper end portion of the side guide 17 described later. 17a is inserted. The annular groove 42 is, for example, 10 to 10 per one folding roll, although it depends on the length of the folding roll 41.
About 18 pieces are formed, and one packer finger 47, one holding bar 61 (or partition bar 71) and one side guide 17 are associated with each annular groove 42.

Further, on the outer peripheral surface of the folding roll 41, the ridges 43, 4 are formed at a total of 4 positions at an angle of 90 °.
43 .. and the intermediate position between the ridges 43, 43 (total of 4
Grooves 44, 44, ... Are formed in the respective locations. And each of these folding rolls 41, 41
Is the folding roll 4 as shown in FIG.
1 side concave groove 44 and transfer roll 31 side convex stripe 3
2 (the ridge 43 on the folding roll 41 side and the concave groove 33 on the transfer roll 31 side, of course), and one side (left side)
The ridge 43 on the side of the folding roll 41 and the concave groove 44 on the side of the other (right side) folding roll 41 face each other.

As shown in FIGS. 12 to 14, the anvil roll 23, the transfer roll 31, and the folding roll 41 have a large number of suction holes for transporting the cut web pieces WS in a state in which they are adsorbed on the outer peripheral surface of the roll. (27, 34, 45) are formed. In the example shown,
For each roll 23, 31, 41, front and rear of the ridges (or anvil knives) 24, 32, 43, and concave grooves 25, 3
Intake holes 27, 34, 45 are opened in front of and behind 3, 44, respectively. It should be noted that each of the intake holes is formed in a large number in the roll axis direction. These intake holes 27, 3
4 and 45 are designed to inhale in each roll only within the range of reference numerals 28, 35 and 46 (FIGS. 12 to 14) shown by chain lines. Therefore, the web piece WS cut by both knives 22 and 24 of the web cutting device 2
As shown in FIG. 13, it moves from the outer peripheral surface of the anvil roll 23 to the outer peripheral surface of the transfer roll 31, and further from the outer peripheral surface of the transfer roll 31 to the outer peripheral surface of the folding roll 41.

Further, in each of the air intake holes formed in the folding roll 41, the air intake holes 4 formed in the concave groove 44 portion.
No. 5 is set so that the suction force is larger than that of the air intake hole 45 formed in the ridge 43 portion. In this example,
As shown in FIG. 14, the suction force of the intake hole 45 (opening only in the concave groove 44 portion) branched from the ventilation hole of reference numeral 45A (the number of branches of the intake hole is small) is large, and that of reference numeral 45B. The suction force of the intake holes 45 (opening to the convex ridge 43 portion and the concave groove 44 portion) branched from the ventilation holes (the number of the intake holes is large) is reduced. In FIG. 14, when the convex strip 43 of the folding roll 41 on the one side (left side) and the concave groove 44 of the folding roll 41 on the other side (right side) meet, the intake air opening in the concave groove 44 portion. The total suction force of the holes 45 becomes considerably larger than the total suction force of the air intake holes 45 that are open to the other ridge 43, and the web pieces WS and WS sent from the left and right sides are superposed. Then, the superposed web is drawn to the outer peripheral surface of the folding roll 41 on the side of the concave groove 44 (the outer peripheral surface of the folding roll on each side is alternately taken). The portion of the web piece WS where the pushing streak WSc formed by the ridge 32 of the transfer roll 31 (intermediate position in the running direction of the web piece) is located in the concave groove 44 portion. When the 44 portion advances to the proximity position of both folding rolls 41, 41, on the outside of the pushing line forming portion of the web piece held by the concave groove portion 44, the respective proximity ends of the two web pieces on the other side are formed. The edges will overlap. Then, when the recessed groove 44 portion further advances by a predetermined angle, at the recessed groove 44 portion, the pushing bar WS of the web piece is pushed.
The edge of each web piece on the opposite side is wrapped and held by the c-forming portion.

In this embodiment, as the means for holding the web folding portion on the outer peripheral surface of the folding roll 41, a suction type means is adopted, but in other embodiments,
A gripping method using a vise may be adopted instead of the suction method. By the way, in the gripping method with a vise, the web folding part is partially gripped at intervals,
In this case, the fold line portion appears to the extent that the gripping portion and the non-grasping portion by the vise can be discriminated (a step is formed in the fold line portion), and the appearance is slightly deteriorated. On the other hand, in the case where the web folding portion is held by the suction type as in this embodiment, there is no step in the folding line portion unlike the gripping method by the vise, but in the case where the suction holding is simply performed, the folding is not performed. The feature is that the lines do not appear clearly. However, in this embodiment, since the pushing streak WSc is formed in advance in the web folding portion, even if the suction type is adopted, a sharp folding line can be revealed.

Left and right folding rolls 41, 41
.. are arranged so that the tip ends of the packer fingers 47, 47 .. This packer finger 4 on each side
7, 47 are driven by a driving means (not shown) that is operated in synchronization with the rotation angle of the folding roll 41.
Alternately rocked up and down, folding roll 4
When the groove 44 part of No. 1 passes both roll proximity parts and is rotated to a predetermined position, the web holding part sucked in the groove 44 part is pushed downward by the tip part of the packer finger 47. To do. When the web is pushed out by the packer fingers 47, the suction action from the intake holes 45 in the concave groove 44 portion is stopped. As described above, in the web folding device 4, the above-described operations are alternately performed, and the folding webs are continuously sent out between the folding rolls 41, 41, and the lifting table 50 described later is sequentially provided.
Stacked on top. When the folding web is removed from the folding roll 41 side to the lifting table 50 side, as shown in FIG. 22 or FIG. It will rise upwards. Moreover, as shown in FIG. 13 or FIG. 21, the folding web folded in this way is
When the concave groove 25 of the anvil roll 23 and the ridge 32 of the transfer roll 31 previously come into contact with each other, the web piece WS
A clear pushing streak WSc is formed at an intermediate portion in the traveling direction of the web folding device 4 in the web folding device 4.
Since it is folded at the Sc portion, the folded portion WSc '(FIG. 39) of the folded web appears sharply (cleanly).

Below the web folding device 4, FIG.
As shown in FIG. 17, a pair of left and right side guides 1 for guiding the left and right sides of the folding web that is sequentially folded.
7, 17 are provided. These side guides 17,
A vertical thin plate 17 is used, and a predetermined interval (interval between the annular grooves 42, 42) in the lengthwise direction of the folding roll 41 under the web folding portion as shown in FIGS. 15 and 16. In addition, as shown in FIG. 17, a large number of folded webs are arranged so as to face each other with an interval slightly wider than the left and right width of the folded web. Further, each of the side guides 17, 17 is installed with its upper end portion 17a inserted into each annular groove 42 of the folding roll 41 by an appropriate depth. The side guides 17, 17 guide the folding webs, which are sequentially folded, to be aligned on the lifting table 50. Further, since the upper end portions 17a of the side guides 17, 17 are inserted into the annular groove 42 by an appropriate depth, for some reason (for example, when the web extrusion timing by the packer fingers 47 is delayed), the web is properly folded. Even if the web is not peeled at the angular position, the web comes into collision with the side guides 17 on either side, and the web can be reliably peeled at the proper position. The folding roll 41 has an annular groove 4
When the side guides 17 are installed, the upper end surface of the side guide 17 is the outer peripheral surface of the folding roll when the side guide 17 is installed. It is necessary to install it with a slight gap between. In this case, when the web cannot be separated successfully at the proper position of the folding roll, the tip of the web may get caught in the gap between the outer circumferential surface of the folding roll and the upper end surface of the side guide. If the folded web is pushed out by the packer fingers while the portion is caught in the gap, the web may be scratched or wrinkled.

This quantitative web laminated body manufacturing apparatus includes an operation speed detecting apparatus 11 for detecting the operation speed of the apparatus.
And a counting device 12 for counting the number of folded web pieces. That is, in this embodiment, as shown in FIG.
6, a small-diameter gear G ₂ is meshed with a large-diameter gear G ₁ attached to the shaft end of one folding roll 41, and the rotation speed of the small-diameter gear G ₂ serves as an operating speed detection device. The rotation speed sensor 11 detects the rotation speed of the small-diameter gear G _{2 and} the counter 12 measures the rotation speed. The operation speed detecting device 11 and the counting device 12 are various rolls 2 as long as they are driven parts driven by the original machine driving device 9.
It can be provided at an appropriate place such as the rotating shaft of 1, 23, 31 or 41.

And a lifting drive device 52 for lifting the lifting table 50.
And a first partitioning device 6 and a second partitioning device 7 for partitioning the folding webs that are folded on the lifting table 50 from the left and right sides, respectively.

As the lifting table 50, an elongated plate-like one is used which is slightly wider than the width of the folded folded web and longer than the width of the continuous web W. A large number of recesses for inserting the inner end portions of the side guides 17, 17 are formed on both left and right sides of the lifting table 50. As shown in FIG. When it is within the range, the lifting table 50 and the side guides 17,
I try not to collide with 17. Further, the lifting table 50 has both longitudinal ends supported by vertical rods 51. In another embodiment, as the lifting table 50, one having a large number of bars arranged side by side at the same height with a small interval can be used.

In this embodiment, the elevating / lowering device 52 includes a belt 54 stretched in the vertical direction as shown in FIG.
A servo motor 53 is used to reversibly travel (a pair of front and rear). A base block 55 is attached to each of the front and rear belts 54, and each base block 55 supports each rod 51 of the lifting table 50 as shown in FIG. The servo motor 53 of the lifting drive device 52 is the controller 1
0 (FIGS. 18 and 19) controls the operation timing, rotation direction and speed (details will be described later), but basically the lifting table 50 receives the folding web from the web folding device 4. Upper position and lifting table 50
The upper and lower web stacks are moved up and down with respect to the lower position.

As shown in FIGS. 18 to 20, the first partitioning device 6 has a narrow and inverted L-shaped presser bar 61, and a presser bar drive device 62 for operating the presser bar 61. ..
Further, the presser bar driving device 62 has an expansion / contraction cylinder 620 for actually moving the presser bar 61 back and forth between a retracted position and a driving position, and a lock device 67 for locking the presser bar 61.

The pressing bar 61 is for pressing the upper surface of the quantitative web laminated body laminated on the lifting table 50, and is installed on the left side of the lifting table 50 in the illustrated example. The presser bar 61 has a presser piece 61a that is laterally oriented and has a considerable length (for example, about 140 mm) at the top.
The pressing bar 61 is used in a large number (the same number as the annular groove 42) with a space between the annular grooves 42, 42 of the folding roll 41. In addition, the presser bars 61, 61.
-Fixes each lower end portion thereof to one shaft 64.

On the other hand, the front and rear rods 5 of the lifting table 50
1 includes a slide block 63 that can slide up and down.
(A pair of front and rear) is provided, and a shaft 64 of the presser bar 61 is rotatably installed between the slide blocks 63.

Telescopic cylinder 62 of presser bar drive device 62
0 is supported by a slide block 63, and a lever 64a in which the movable side of the telescopic cylinder 620 is attached to a shaft 64
Connected to. The shaft 64 can be reversibly rotated (the pressing bar 61 can be swung left and right) by expanding and contracting the expanding and contracting cylinder 620. The operation range of the presser bar 61 by the telescopic cylinder 620 is as shown in FIG. 19 or FIG.
1 is a leftward retracted position (a position shown by a solid line) that does not interfere with the folding operation of the web, and a rightward driving in which the tip of the pressing piece 61a is about to be folded on the elevating table 50 to enter a predetermined depth between the folding webs. Position (FIG. 19 or FIG. 22)
It is set so that it can be swung between the position shown in FIG. Although the pressing action of the presser bar 61 becomes more reliable as the driving depth becomes deeper, the pressing bar 61 may break through the web at the tip of the pressing piece 61a if the driving depth is made too deep. It is preferable to set the driving depth to about 70 to 80% in the width direction of the web laminate.

The lock device 67 allows the presser bar 61 to move to the driving side in an instant.
As shown in FIG. 3, the lock member 69 is pivotally attached to the slide block 63, and a telescopic cylinder (a solenoid is also possible) 68 for swinging the lock member 69.
The telescopic cylinder 68 is fixedly attached to a predetermined position on the frame side of the machine body. The lock member 69 is
In this embodiment, the extension operation of the telescopic cylinder 620 that serves as the presser bar drive device 62 is restricted. Then, as shown in FIG. 19, the locking device 67 is configured such that when the telescopic cylinder 620 serving as the presser bar driving device 62 is in a contracted state (the presser bar 61 is at the right standby position), the telescopic cylinder 68 of the lock device 67 is moved. By contracting, the rod of the telescopic cylinder 620 is locked by the lock member 69, and on the other hand, the telescopic cylinder 68 of the locking device 67 is extended, whereby the lock member 69 is arc-rotated and unlocked. . The lock device 67 is operated by a signal from the controller 10 as described later, but before the lock member 69 is unlocked, the telescopic cylinder 620 serving as the presser bar drive device 62 is operated toward the extension side. Every other time (actually, it is locked by the lock member 69 and therefore does not extend), the pressing operation of the presser bar 61 is instantaneously performed simultaneously with the unlocking operation of the lock member 69.

Slide block 63 and lifting table 50
An expandable cylinder 65 for moving the slide block 63 up and down with respect to the rod 51 is provided between the lower ends of the rods 51, as shown in FIGS. This telescopic cylinder 65 has a function of maintaining the holding bar 61 at the upper standby height position when the lifting table 50 slightly moves down (the rod 51 also moves down) during stacking of folding webs, as described later. That is, while the elevating table 50 is slightly moving down, the telescopic cylinder 65 continues to operate toward the extension side and constantly urges the slide block 63 upward. However, the slide block 63 is stopped by the stopper 66 (see FIG. Two
Since it is abutted against 0), it is maintained at a fixed position, and each presser bar 61 is also maintained at an upper standby height position. Further, this telescopic cylinder 65 is the same as the counting device 1 described above.
When the count-up signal from 2 is issued, the extension state is locked (the slide block 63 becomes unable to slide with respect to the rod 51), and thereafter, as the lifting table 50 moves downward, the presser bar is moved. 61 also comes down.

The telescopic cylinder 65 (FIGS. 19 and 20) for moving the slide block up and down is provided immediately after the lowering of the lifting table 50 is started after the pressing bar 61 is driven into the web stack on the lifting table 50. 25, the presser bar 61 is moved from the solid line position to the chain line position (reference numeral 6).
It operates so as to move it down a little to the 1'position (for example, about 10 mm). That is, the telescopic cylinder 65
Immediately after the lowering of the lifting table 50 is started, the slide block 63 is reduced by a slight amount, and the slide block 63 is moved down by a certain height with respect to the rod 51 of the lifting table 50.
As a result, the presser bar 61 is also moved downward so that the presser piece (reference numeral 61a ') compresses the web laminated body X on the elevating table 50 by a slight height. In this way, when the web laminated body on the lifting table 50 (separated into the quantitative web laminated body Y) is compressed by the pressing piece 61a ',
When the quantitative web laminated body Y is clamped and held by the upper surface of the lifting table 50 and the lower surface of the pressing piece 61a ′, and when the quantitative web laminated body Y is moved downward together with the lifting table 50, as shown in FIGS. In addition, the quantitative web laminated body Y on the lifting table 50 can be lowered in a stable posture. In addition, as for the telescopic cylinder 65 (FIGS. 19 and 20) for vertically moving the slide block, the lifting table 50 is shown in FIG.
When it is moved down to the discharge height position shown in FIG. 5, it is operated so as to extend by the above-described reduction amount which is reduced immediately after the start of the downward movement of the lifting table 50. Then, as shown in FIG. 28, the presser bar 61 together with the slide block 63 is moved upward by a slight height as indicated by reference numeral 61 '(at that time, the presser piece 61a is at the position of reference numeral 61a'), and the presser bar 61 is pressed. The downward pressing force on the quantitative web laminated body Y by the piece 61a comes to be released. When the pressing force of the pressing piece 61a 'is released in this way, the pressing piece 61a' is released.
It is possible to push the quantitative web laminated body Y on the elevating table 50 from the elevating table 50 by the pusher 81 while a'is being driven into the quantitative web laminated body Y side.

As shown in FIGS. 18 to 19, the second partitioning device 7 has a narrow width and an inverted L shape (opposite to the presser bar 61).
The partition bar 71 and the partition bar drive device 72 for operating the partition bar 71. The partition bar driving device 72 includes a telescopic cylinder 720 that actually moves the partition bar 71 back and forth between a retracted position and a driving position, a locking device 77 that locks the partition bar 71, and the (partition bar 71, telescopic cylinder 720, And a lift drive device 75 for moving the lock device 77) up and down.

A lifting drive device 75 for the second partition device 7.
As shown in FIG. 18, a belt 752 (a pair of front and rear) stretched in the vertical direction is reversibly run by a servo motor 751.
The servomotor 751 is used in the controller 10 (see FIG.
8, FIG. 19) controls the operation timing, rotation direction and speed.

A base block 753 is attached to each of the front and rear belts 752 of the lifting drive device 75 for the second partition device 7, and each base block 753 is attached.
Supports a telescopic cylinder 76 (a pair of front and rear) for adjusting the partition bar 71 to the left and right. A mounting base 761 (a pair of front and rear) of the partition bar 71 is attached to the movable-side tip of each of the telescopic cylinders 76.

The partition bar 71 serves to temporarily receive a subsequent folding web (web laminated body) which is folded by the web folding device 4 instead of the lifting table 50.
Similar to the presser bar 61, the partition bar 71 has a partition piece 71a that is laterally oriented and has a considerable length (for example, about 150 mm) in the upper portion. The partition bar 71 is used in a large number (the same number as the annular groove 42) at intervals between the annular grooves 42, 42 of the folding roll 41. or,
The partition bars 71, 71, ... Have their lower ends fixed to a single shaft 74. The shaft 74 is rotatably installed between the mounts 761.

Telescopic cylinder 7 of partition bar drive device 72
20 is supported by a mounting base 761 and the movable side of the telescopic cylinder 720 is connected to a lever mounted on a shaft 74. The shaft 74 can be reversibly rotated (the partition bar 71 is swung left and right) by expanding and contracting the expandable cylinder 720. The operating range of the partition bar 71 by the telescopic cylinder 720 is as shown in FIG. 19 or FIG.
However, the right retracted position (the position shown by the solid line) that does not interfere with the folding operation of the web, and the left driving position where the front end of the partition 71a is about to be folded up to a predetermined depth between the folded webs (see FIG. 19 or FIG. It is set so that it can be swung with respect to the position indicated by the chain line in FIG.
The driving depth of the partition bar 71 can be adjusted by the telescopic cylinder 76 for advancing / retreating.

The lock device 77 is similar to that of the first partitioning device 6 and allows the partition bar 71 to be instantaneously operated toward the driving side. That is, as shown in FIG. 19, the lock device 77 has a lock member 79 pivotally attached to a mount 761 portion and a telescopic cylinder (a solenoid is also possible) 78 for rocking the lock member 79. There is. The lock member 79 restricts the extension operation of the telescopic cylinder 720 of the partition bar drive device 72. Then, as shown in FIG. 19, in the locking device 77, when the telescopic cylinder 720 of the partition bar driving device 72 is in the contracted state, the telescopic cylinder 78 of the locking device 77 is contracted, so that the telescopic cylinder 720 is locked by the lock member 79. By locking the rod and, on the other hand, extending the telescopic cylinder 78 of the locking device 77, the locking member 7
The lock is released by rotating 9 in an arc.

Further, in the first partition device 6 and the second partition device 7, as shown in FIG. 23, the driving height of the holding bar 61 of the first partition device 6 is set to the driving of the partition bar 71 of the second partition device 7. The position is higher than the height. And
At almost the same time as the pressing bar 61 is driven (before the partition bar 71 is driven), the lifting / lowering drive device 52 instantaneously moves the position to a position slightly lower than the driving height of the partition bar 71 (only in the range of the height H). I am trying to lower it.

As described above, when the presser bar 61 is driven from a position higher than the normal driving position (a position slightly lower than the driving height of the partition bar 71), the pressing piece 61a of the pressing bar 61 is moved as shown in FIG. , The upper and lower folding webs opened in the form of ">" can be driven with a sufficient margin, and the front end of the pressing piece 61a does not push the web piece WS forward (or the pushing range is slight). . Further, when the folded web piece WS is removed from the folding roll 41 side by the packer finger 47, as shown in FIG. 22 or FIG.
The central portion of S may be swollen upward due to the wind, but even when the central portion of the web piece WS is upwardly swollen in this way, reference numeral 61a ′ in FIG. As shown by, the pressing piece 61a can be driven to the upper side of the raised portion. Therefore, it is possible to prevent problems such as deformation, displacement, and damage of the folding web (particularly the uppermost folding web of the quantitative web laminate) due to the pressing of the pressing bar 61. Further, since the pressing bar 61 is rapidly lowered by a predetermined height H almost at the same time as the pressing of the pressing bar 61 (before the partition bar 71 is driven), the pressing bar 61 is moved to the high position as described above. Even if it is designed to be driven from the
Does not get in the way of the partition bar 71 to be driven next.

The lifting drive device 52 of the lifting table 50 is
The servo motor 53 operates as follows. First, as shown in FIG. 17 or 18, while the folding webs are sequentially stacked on the lifting table 50, the lifting table 5
0 is finely moved continuously or intermittently according to the web laminating speed. Then, a predetermined number of web pieces are folded and stacked on the elevating table 50, and at the same time the pressing bar 61 is driven, the elevating table 50 is instantaneously moved to a position 50 'in FIG. After descending, the elevating table 50 is descended to the discharge height position shown in FIG. 27 at a normal descending speed, and then the quantitative web laminated body Y on the elevating table 50 is discharged, and then at a predetermined speed. It operates to raise to the next web stack receiving position shown in.

By the way, when the descending speed of the fine motion of the lifting table is constant when the folding webs are stacked on the lifting table 50, the operating speed of the apparatus is changed.
The bulk density of the web laminated body X laminated on the elevating table 50 is changed. That is, if the fine movement descent rate of the lifting table 50 is constant, the bulk of the quantitative web laminated body Y laminated on the lifting table 50 becomes too large (the bulk density becomes low) when the operating speed is slow. On the contrary, when the operating speed is fast, the bulk of the identified amount web laminate Y becomes too small (bulk density becomes high) and the texture may be impaired. Further, if the above-described fine movement descending speed is kept constant, the thickness of the web used changes (for example, a thin web for tissue, a thick web for towels, etc.).
In addition, the volume, texture, etc. of the manufactured quantitative web laminated body Y also change depending on the presence or absence of embossing. In order to improve the occurrence of such a phenomenon (changes in the volume, texture, etc. of the quantitative web laminated body Y), in the quantitative web laminated body manufacturing apparatus shown in the figure, the fine motion descending speed of the lifting table 50 is adjusted by checking the operating state. However, it can be adjusted by an external operation.

That is, in this quantitative web laminated body manufacturing apparatus, the rotation speed of the servo motor 53 of the lifting drive device 52 when the lifting table 50 is slightly moved down is specified by a digital method from the outside, whereby the lifting table 50 is moved. 5
The fine movement descent speed of 0 can be adjusted appropriately.
For example, a quantitative web laminated body Y for a boxed tissue as shown in FIG. 38 (usually 200 sets with a total thickness of 70 to 8).
(0 mm), it is advisable to set the fine movement descent speed of the lifting table 50 to such a speed that the lifting table 50 is lowered by, for example, 0.35 to 0.4 mm each time one web piece is folded on one side. In this way, if the fine movement descending speed of the lifting table 50 can be adjusted from the outside, the volume of the manufactured quantitative web laminated body Y can be adjusted to a suitable range and the texture of the folding web can be improved, and Since the descending speed can be adjusted while observing the operating state, it is possible to change the bulk density to a desired one even during operation.

The lift drive device 75 of the second partition device 7 is
After the partition bar 71 is driven by the servo motor 751, the partition bar 71 (actually, the base block 75
3) is finely moved continuously or intermittently according to the web laminating speed, and as shown in FIG.
Then, after the web laminated body X on the partition bar 71 is replaced and the partition bar 71 retreats, the partition bar 71 is operated to move up to the initial position shown in FIG. The fine movement lowering speed of the partition bar 71 is always set to be equal to the fine movement lowering speed of the lifting table 50. That is, the servo motor 75 for slightly lowering the partition bar 71
The rotation speed of 1 can be set at the same time by the operation of setting the rotation speed of the servo motor 53 when the lifting table 50 is slightly moved down. The speeds (the fine movement descending speeds of the lifting table 50 and the partition bar 71) can be set at the same time and at the same speed.

In the quantitative web laminated body manufacturing apparatus of this embodiment, as shown in FIG. 38, when the quantitative web laminated body Y is stored in the paper box B for use, the uppermost web piece WS is used.
In order to make it easy to take out the paper from the take-out port Bb of the paper box B, the folding devices 15, 16 (FIG. 1) for folding the upper half of the uppermost web piece WS into a half width (folding part WSd).
8, FIG. 27, and FIG. 29) are provided. The folding devices 15 and 16 are provided on the left and right sides of the lifting table lifting portion near the upper part, and the telescopic cylinders 151 and 161 respectively.
The push plates 152 and 162 are attached to the movable-side tip portion of the configuration. It should be noted that each of the push plates 152 and 162 is formed by arranging small-width bars side by side at a small interval. Then, as shown in FIG. 26, the folding devices 15, 16 separate the quantitative web laminated body Y on the elevating table 50 from the subsequent folding web, and thereafter, the web laminated body X laminated on the partition bar 71. The hanging piece WS ₂ of the web piece WS located at the bottom of the is processed as follows. That is, as shown in FIG. 27, first, the telescopic cylinder 151 of the folding device 15 on the left side is extended, the hanging piece is folded back to the right side by the push plate 152 thereof to bring it closer to the lower surface of the partition bar 71, and then the folding on the right side. Telescopic cylinder 161 of device 16
Is extended and the folded piece previously folded back by the push plate 162 is folded to the left by half the width. Then, while being folded back in half, the entire web laminated body X on the partition bar 71 is supported by each support bar 19 of the temporary receiving device 19 described below.
1 After remounting, the telescopic cylinder 15 of each folding device
1, 161 is contracted to reduce the width of the lowermost half of the web piece to a half width, and the support bar 19
Can be supported on one. In addition, this folded part WS
d is formed on the lower surface side of the quantitative web laminated body Y. By turning the quantitative web laminated body Y upside down in a later step as will be described later, as shown in FIG.
d can be positioned on the upper surface side.

The temporary receiving device 19 includes a large number of support bars 19
1 are connected side by side in the front-rear direction with a small space therebetween, while the supporting bar 191 is moved forward and backward by the telescopic cylinder 192. It is configured so that it can be raised and lowered. Lifting drive device 193
Moves the belt 195 up and down by the servomotor 194, and the base block 196 is attached to the belt 195.
Is installed. A telescopic cylinder 192 is attached to the base block 196 so that the support bar 191 can be moved up and down together with the telescopic cylinder 192 by operating the servomotor 194 in either forward or reverse directions. . And this temporary receiving device 1
27, the support bar 191 is located below the push plates 152, 162 of the folding devices 15, 16 as shown in FIG. As shown in the figure, the web is placed on the partition bar 71 just below the web laminated body X, and then the servo motor 194 moves the support bar up to the position indicated by reference numeral 191 ″. After receiving the laminate X, the partition bar 71 is retracted, and the empty lifting table 50 is moved upward as shown in Fig. 29, and the lifting table 50 receives the web laminate X on the support bar 191. Then, the telescopic cylinder 192 is contracted and the support bar 191 is retracted (the state shown in FIG. 30).

In this temporary receiving device 19, the support bar 1
Immediately after the web laminated body X is supported by 91 until the web laminated body X on the support bar 191 is received by the elevating table 50, the elevating drive device 193 (servo motor 194) finely moves at a speed corresponding to the web folding speed. Can be lowered. Further, the setting / changing operation of the fine movement lowering speed of the temporary receiving device 19 at this time is simultaneously performed by the setting / changing operation of the fine movement lowering speed of the elevating table 50.

Further, this quantitative web laminated body manufacturing apparatus includes:
As shown in FIG. 19, FIG. 25, FIG. 26, and FIG. 28, it is provided at the tip end of each presser bar 61, 61 ... Of the first partitioning device 6 and the lower end of the mounting base 761 of the second partitioning device 7. An air blow device 13 is provided for blowing air from each air nozzle 18.

A plurality of air nozzles 18 mounted on the mounting base 761 of the second partitioning device 7 are used at predetermined intervals in the depth direction in FIGS. 19 and 25 to 28.
Further, as shown in FIG. 27, this air nozzle 18 is located on the opposite side of the holding bar 61 from the position close to the lifting table lifting area while the lifting table 50 on which the quantitative web laminated body Y is placed is being lowered. The air B is blown in a substantially horizontal direction on the side of the lifting table lifting area. Further, the installation height of the air nozzle 18 is determined by the mounting base 7
Although 61 is slightly moved up and down by being slightly moved down together with the partition bar 71, the quantitative web laminated body Y
When lowering the lifting table 50 on which the
Shortly before 0 reaches the lowermost moving position (the discharging position in FIG. 28), the height position is set such that the upper surface of the quantitative web laminated body Y on the lifting table 50 corresponds to the horizontal direction.
The operation of the air nozzle 18 will be described later.

The air blower 13 comprises a blower 130.
Compressed air from the air nozzle 18 is provided through the two pipes 132 and 181 branched from the supply pipe 131 at the tip of the holding bar 61 and the lower end of the mounting base 761, respectively.
It is designed to be blown out from each.

That is, the blower 130 is provided on the presser bar 61 side.
Compressed air from the supply pipe 131, the one pipe 132,
After passing through branch pipes 133 that are branched from the pipe 132 for each of the presser bars 61, 61, ...
Each of the pressing pieces 61a is made to blow out through 34. On the air nozzle 18 side, compressed air from the blower 130 is blown out from the air nozzle 18 through the supply pipe 131 and the other pipe 181.

In this embodiment, air is blown out from the presser bar 61 side by the solenoid valve 135 provided in the pipe 132.
(See FIGS. 25, 26, and 28), immediately after the pressing bar 61 is driven between the folding webs as shown in FIG. 25, the quantitative web laminated body Y is extruded by the pusher 81 as shown in FIG. 28. Is carried out (the quantitative web laminated body on the elevating table 50 is extruded from the elevating table 50).

In this embodiment, air is blown out from the air nozzle 18 side after the lift table 50 starts to move downward by the solenoid valve 180 (see FIGS. 25, 26 and 28) provided in the pipe 181. For example, as shown in FIG. 26, the time from before the quantitative web laminated body Y on the lifting table 50 is lowered to the installation height of the air nozzle 18 to when the lifting table 50 is lowered to the lowest moving position as shown in FIG. I'm just trying to do it. In addition, this air nozzle 1
As shown in FIG. 27, the air blowing by 8 is effective when the upper surface portion of the quantitative web laminated body Y on the lifting table 50 passes the installation height of the air nozzle 18 (the action will be described later). ).

The air blowout pressure (or blowout speed) from the tip end portion of each presser bar 61 and the air blowout pressure (or blowout speed) from the air nozzle 18 are respectively determined by the pipes 132,
It is advisable to provide a flow rate adjusting valve in 181 and adjust accordingly.

The air blowing from the tip of the presser bar 61 acts as follows in each stage.

First, when separating the quantitative web laminated body shown in FIG. 25, the folded piece W of the upper and lower web pieces to be separated.
A part Aa of the blown air A flows between S ₁ and WS ₂ , so that the folded pieces WS ₁ and WS ₂ can be smoothly separated. That is, in the state where the web pieces are folded together, the folded pieces WS ₁ and WS ₂ of the web pieces on each side are joined together, and the folded pieces WS ₁ and WS ₂ are vertically arranged as shown in FIG. When they are to be separated, the folded pieces WS ₁ and WS ₂ are usually pulled toward each other by the frictional force between the folded pieces, so that the folded shape of the folded piece WS ₁ of the uppermost layer is disturbed. However, as described above, the presser bar 61
If air is blown from the tip of the folded back pieces, an air layer is formed between the folded back pieces, and the folded back pieces WS ₁ and WS ₂ can be smoothly separated. Therefore, effect that folds form of folded piece WS ₁ web piece to be separated is not easily disturbed (especially the tip of該折-back piece WS ₁ is less likely to protrude outwardly from the sides of the quantitative web laminate Y) is obtained .

Next, in the lowering stage of the lifting table 50 shown in FIG. 26, the upper portion of the quantitative web laminated body Y is held by the holding bar 61, but the folded-back piece WS ₁ of the uppermost web piece is held by the holding bar 61. If the lowering speed of the lifting table 50 is higher than the speed (free fall speed) at which the folding piece WS ₁ moves downward due to its own weight, the folding piece WS _1
The downward movement speed due to the self-weight of ₁ cannot keep up with the downward movement speed of the lifting table 50, and the folding piece W at the uppermost portion.
S ₁ starts to follow while fluttering, and in the final downward movement, the folded piece WS ₁ may be rolled up or air may enter and rise. This tendency is particularly strong in the case of a thin web such as tissue paper. By the way, as shown in FIG. 26, when the air A is blown from the tip of the presser bar 61 during the downward movement of the lifting table 50, the uppermost web piece is folded back so as to wrap the tip of the presser bar 61. As a result, most of the air blown into the folded-back portion is reversed inside the folded-back portion and the folded-back piece WS
It will be released from the tip side of ₁ . At this time, the air outlet (the tip of the presser bar) in the folded portion
Although the pressure is higher than the atmospheric pressure on the front side, the air is blown out to the outside on the air outlet side, so that the pressure becomes negative, and the folded piece WS ₁ is forcibly converged to the holding bar 61 side. be able to. Therefore, even if the lowering speed of the lifting table 50 is faster than the lowering speed (free fall speed) of the folding piece WS _{1 due} to its own weight, the folding piece WS ₁ is less likely to flutter during the downward movement of the lifting table 50. The folded back piece WS ₁ can be converged and superposed on the holding bar 61 in a state where it is stretched as normally as possible. In addition, the web folding ability (speed) in the web folding device 4 part has a sufficient surplus capacity, and by increasing the downward movement speed of the lifting table 50,
Overall operating speed can be increased (manufacturing capacity can be improved).

Further, as shown in FIG. 28, when the elevating table 50 is lowered to the lowermost position, the presser bar 61 is slightly moved upward as indicated by reference numeral 61 ', and then the pusher 81 moves the elevating table 50 onto the elevating table 50. The quantitative web laminated body Y is extruded. However, if air is blown from the tip of the presser bar 61 ′ at that time, the folded piece WS ₁ is slightly separated from the upper surface of the presser bar 61 by the air flow A. At the time of extruding the quantitative web laminated body Y, the folded piece WS ₁ is not pulled by the friction with the holding bar 61. Therefore,
Even if the quantitative web laminated body Y is extruded in a state in which the presser bar 61 is inserted between the uppermost folding webs, friction does not occur between the return piece WS ₁ and the presser bar 61, so that the return piece W
S ₁ is no longer disturbed by the presser bar 61,
When the folded back piece WS ₁ is normally spread, the folded piece WS ₁ converges on the upper portion of the quantitative web laminated body Y by its own weight. or,
In this way, when the presser bar 61 is removed, if the air is blown out from the tip of the presser bar 61, the folded bar WS ₁ is not pulled by the presser bar 61 as described above. The tip of ₁ is a quantitative web laminate Y
It also has the effect of making it more difficult to extend to the outside of the left side surface. In this embodiment, the quantitative web laminated body Y on the elevating table 50 is moved when the presser bar 61 is removed from the folding web, but in another embodiment, the quantitative web laminated body Y is moved. Alternatively, the holding bar 61 inserted into the folding web may be retracted to remove the holding bar 61. Even in that case,
This is performed while blowing air from the tip of the presser bar 61.

The air blown out from the air nozzle 18 is
As shown in FIG. 27, when the quantitative web laminated body Y on the lifting table 50 passes downward through the installation height part of the air nozzle 18, the web folding piece WS ₁ located at the uppermost part of the quantitative web laminated body Y. Forcibly converges on the presser bar 61.
It is for polymerizing. That is, when air is not blown from the air nozzle 18, the lowering speed of the uppermost web folding piece WS ₁ of the lifting table 50 (the self-weight falling speed of the web folding piece WS ₁ and the holding bar 6 is
(1) The folding piece WS ₁
Becomes unable to keep up with the lowering speed of the lifting table 50, and the folded piece WS ₁ flickers,
An air nozzle 1 is provided near the upper surface of the fixed-quantity web laminate Y that is moving downward.
When the air B from 8 is blown, the uppermost folded piece WS ₁ can be forcibly converged to the holding bar 61 side by the air pressure. Therefore, even if the lowering speed of the lifting table 50 is further increased, the folding piece WS ₁ is forcibly forced by the lowering stroke of the lifting table 50 (the lowest movement position or immediately before it) and the freedom of the folding piece WS _{1 due} to its own weight. It can be pressed against the presser bar 61 side at a speed faster than the falling speed, and the folded back piece WS ₁ can be converged and superposed on the presser bar 61 in a more normally extended state. .

By the way, in the case of an insulating material such as paper, the web comes into contact with various devices such as air and rolls at the stage of manufacturing the base paper or the step of processing the base paper into a product (quantitative web laminate). Friction causes the folding webs to become charged with static electricity (especially this tendency becomes more pronounced in the dry climate of winter). It should be noted that it is known that the static electricity charged on this type of web is mixed with a portion where a large number of (+) polarity ions are collected and a portion where a large number of (−) polarity ions are collected even in one web piece WS. Has been. Then, in the process of manufacturing the quantitative web laminated body Y, if the web is charged with static electricity or if the web is newly charged with static electricity, the following problems occur.

That is, when static electricity is charged on the folding web folded on the elevating table 50, the static electricity tends to cause the web pieces to stick to each other. In particular, for thin webs such as tissue paper, the quantitative web laminate Y
When a potential difference occurs between the uppermost web folding piece WS ₁ and the web located on the lower surface thereof, the web folding piece W 1
S ₁ may stick to the web underneath without proper spreading. For example, in the upper and lower webs, when charged parts of the same polarity come close to each other, the webs repel each other, and when charged parts of opposite polarity come close to each other, they become attracted to each other. The web folded piece WS ₁ may polymerize in a partially swollen state (see, for example, FIG. 9). In this way, when the long web of the folded back web is not stretched cleanly and the fixed length web laminate is cut into final product lengths,
For example, as shown in FIG. 10, the uppermost web piece may not accurately become a square in the stretched state, which lowers the commercial value.

In order to solve such a problem, this quantitative web laminated body manufacturing apparatus is provided with a means for removing static electricity charged on the web located at the uppermost part of the manufactured quantitative web laminated body Y. That is, in this quantitative web laminated body manufacturing apparatus, as shown in FIG. 19, FIG. 25, FIG. 26, and FIG.
By incorporating air ions for static electricity removal into the air blown out from the tip of the holding bar 61 and the air nozzle 18, the air ions are blown onto the uppermost folding web. As the ion generator 14, for example, a (+) polar ion and a (-) polar ion, which are called a pulse DC system, are used.
Those capable of being generated in a state in which polar ions are mixed respectively are suitable. Then, the mixed air ions generated by the ion generating device 14 and having the ions of (+) and (-) polarities mixed therein are sent into the supply pipe 131 of the air blow device 13 via the adjusting valve 14a, and are pressed. Air ions for static electricity removal are blown out together with the blown air A and B from the tip of the bar 61 and the air nozzle 18.

In this way, when air ions for static electricity removal (mixed with ions of each polarity) are discharged together with the air A and B blown out from the tip of the presser bar 61 and the air nozzle 18, the air ions are the maximum. By contacting the surface of the upper web and neutralizing the static electricity charged on the web, the static electricity can be removed from the web. That is, a portion where a large number of (+) polar ions are gathered and a portion where a large number of (-) polar ions are gathered are mixed on the web side, but there are also (+) polar ions in the blowing air A and B.
(−) Polar ions are mixed, and the (+) polar ions in the air A and B are attracted to the (+) polar ions on the web side, while the (−) polar ions are blown to the (−) polar ions on the web side. The (+) polar ions in the air A and B are attracted, and the bipolar static electricity charged on the web side is neutralized.

When the static electricity is removed from the web (particularly, the uppermost folded web) in this manner, the folded-back piece WS ₁ located at the uppermost portion of the quantitative web laminated body is less likely to stick to the lower surface web, The folded piece naturally expands and polymerizes nicely. Further, when the uppermost web is polymerized in a state in which the web is neatly spread in this way, as shown in FIG. 9, long quantitative web laminated bodies Y for a plurality of products are manufactured, and the long quantitative web laminated bodies are manufactured. Even in the case of cutting into final product lengths in a later step, the cuts of the uppermost web piece are not aligned and the web piece is not deformed and cut (the cut end is shown in FIG. 10, for example. There is no inclination as shown by the reference numeral WSe and no step is formed as shown by the reference numeral WSf).

By the way, when a predetermined number (for example, 100 sheets on one side, which is the number of products) of web pieces are folded on the lifting table 50, a count-up signal from a counting device (hereinafter, referred to as a counter) 12 shown in FIG. S ₁ (Fig. 19)
Is issued to the controller 10, while the current driving speed detection value (rotational speed detection signal S _{2 of the} folding roll 41) is output from the driving speed detection device (hereinafter referred to as a rotation speed sensor) 11 that detects the driving speed. It is emitted toward the controller 10.

The first partitioning device 6 and the second partitioning device 7 are adapted to start their operations based on the count-up signal S ₁ from the counter 12, respectively. The operation start timings of the partition devices 6 and 7 (the presser bar drive device 62 and the partition bar drive device 72) are set to sequentially increase as the rotation speed detection value (signal S ₂ ) from the rotation speed sensor 11 increases, and the presser foot is pressed. The bar 61 and the partition bar 71 are always driven at appropriate timing regardless of the change in the driving speed. The partition bar 71 is set so as to be driven in slightly after the pressing of the presser bar 61 (by the time when the folding roll 41 rotates at an angle of 45 °). Will be mainly described. That is, in FIG.
₁ , V ₂ and V ₃ indicate different operating speeds of the manufacturing apparatus of this embodiment. For example, V ₁ is the peripheral speed of the folding roll 41 (in other words, the web traveling speed).
At a low speed of about 50 m / min, V ₂ is 1 / min
00m about the middle driving speed, V ₃ is the same per minute 150m
The high speed limit operating speeds are shown respectively.
Further, reference numeral T ₁ is a time point when a count-up signal is transmitted from the counter 12, reference numeral T ₂ is a time point when the presser bar driving device 62 starts operating in the bar driving direction, and reference numeral T ₃ is a presser bar 6.
1 shows the time when the driving of 1 is completed. Also, the symbol P
₁ web position in the count-up signal origination T _1, reference numeral P ₀ represents the web position at the bar driving proper timing T ₃ of the presser bar 61. The time T ₁ at which the count-up signal is transmitted is the time when the counter 12 counts up the target number of web pieces regardless of the operating speed of the apparatus. Further, the time from the operation start time T ₂ of the presser bar driving device 62 to the driving completion time T ₃ of the presser bar 61 is also constant.

In this control method, as shown in FIG. 24, as the operating speed of the device increases, the presser bar drive device 62 starts from the count-up signal transmission time point T _1.
The time T ₂ at which the operation starts is gradually increased, and even if the web traveling distance after the simultaneous point T ₂ changes like the symbols U ₁ , U ₂ and U ₃ , the pressing of the presser bar 61 always causes the web to move. The process is completed when the bar driving proper position P ₀ is reached. Specifically, as shown in FIG.
Generates a count-up signal S ₁ , the signal S ₁ is input to the controller 10, while the rotation speed sensor 11 outputs a current operation speed (rotation speed of the folding roll 41) detection signal S ₂ of the controller 1 to the controller 1.
Input to 0. Then, from the controller 10 to the presser bar drive device 62, the operation start signal S ₃ , at the timing corresponding to the current operating speed (for example, V _{1 to} V ₃ ).
Output S ₄ . The presser bar driving device 62 has a telescopic cylinder 620 and a locking device 67, and the locking device 6 is preceded by the operation start signal S ₃ to the telescopic cylinder 620.
The operation start signal S ₄ to the telescopic cylinder 68 of No. 7 is output with a slight delay. Immediately after that, the controller 10 outputs the respective operation start signals S ₅ and S ₆ to the telescopic cylinder 720 of the partition bar driving device 72 and the telescopic cylinder 78 of the locking device 77 with a slight time difference. In this embodiment, the rotation speed detection value detected by the rotation speed sensor 11 is divided into a large number of minute ranges, and the operation to the presser bar drive device 62 (and the partition bar drive device 72) is started for each range. I try to assign timing.

FIG. 24 shows an example of the amount of change in the operation start timing for the bar driving device (for example, the presser bar driving device 62) corresponding to the change in the operating speed of the device.
When the operating speed of the device (peripheral speed of the folding roll 41) is 50 m / min, which is indicated by V ₁ , the time Tb ₁ from the above-mentioned count-up signal transmission time T ₁ to the bar driving device operation start time T ₂ is 66/1000. and second, the time Tb ₂ from the count-up signal transmission time T ₁ when min 100m of the driving speed is indicated by V ₂ to the working start time T ₂ of the bar driving device and 33/1000 seconds, the operation speed Count-up signal transmission point T at 150 m / min indicated by V ₃
Time Tb ₃ from ₁ to time point T _{2 at} which the bar driving device starts operating
Is set to be 22/1000 seconds, and the operation start timing of the bar drive device is set earlier as the operating speed of the entire device becomes faster.

When the operation start timings of the presser bar drive device 62 and the partition bar drive device 72 are controlled as described above in accordance with the operating speed of the entire device, a predetermined number of web pieces are folded on the lifting table 50. Each time it is caught, the presser bar 61 and the partition bar 71 can be driven between the upper and lower folding webs at proper timings, and the webs are damaged due to the deviation of the driving timings of the bars 61 and 71, or the troubles such as the failure of the driving. Will not occur. Therefore, it becomes possible to speed up the operation speed of the apparatus to, for example, the maximum capacity of the web folding by the web folding apparatus 4. In this quantitative web laminated body manufacturing apparatus, even with a thin web such as a tissue paper, a steady operation speed (surface peripheral speed of the folding roll 41 = running speed of the web material)
Can be processed at about 130 m / min (80-90 m / min in the past), and 150 m / min at the critical high speed.
It is possible to perform processing of about 100 m / min in the past.

Below the lifting portion of the lifting table 50,
A discharging device 8 for discharging the separated quantitative web laminated body Y to the next process side is provided on the lifting table 50. As shown in FIG. 31, the discharging device 8 includes a pusher 81 for extruding the quantitative web laminated body Y on the elevating table 50 lowered to a predetermined downward movement position, and a conveyer conveyor for conveying the extruded quantitative web laminated body. 82.

Further, in this embodiment, a web laminated body processing apparatus 80 is provided between the pusher 81 and the transfer conveyor 82. The web laminated body processing apparatus 80 compresses the quantitative web laminated body Y to eliminate the air between the folded webs (to reduce the bulk), and, as will be described later, forms a web piece WS at the upper end of the quantitative web laminated body. The processing is performed when the web protrusion WSa occurs. still,
The cause of the web protrusion WSa and the specific configuration of the web laminate processing apparatus 80 will be described in detail later.

In this embodiment, the pusher 81 is the same as that shown in FIG.
A single telescopic cylinder 8 that extends in two stages as shown in 2.
1a. That is, this telescopic cylinder 81a
In FIG. 32, the push plate is located on the left side of the ascending / descending position of the ascending / descending table 50 indicated by reference numeral 81b (see FIG. 3).
1), an intermediate extension state in which the push plate is advanced to the position indicated by reference numeral 81b '(state in FIG. 36), and the push plate is indicated by 8
1b ″, the pusher 81 can be stopped at each of three positions, that is, the most extended state (the state shown in FIG. 37) in which the pusher 81 is extended to the first stage (the push plate in FIG. 32). Moves from the position 81b to the position 81b '), as shown in FIG.
The quantitative web laminated body Y on 0 is extruded to the holding body 804 side,
When the second stage is extended (the push plate moves from the position 81b ′ to the position 81b ″ in FIG. 32), the quantitative web laminated body Y on the holding body 804 side is conveyed in a bead shape as shown in FIG. It is adapted to be extruded to the 82 side.

Further, the telescopic cylinder 8 of the pusher 81
1a is designed to extend at the same speed as the traveling speed of the conveyor 82, particularly during the second stage extension (the push plate moves from 81b 'to 81b "in FIG. 32). In the example, the traveling speed of the transport conveyor 82 and the extension speed of the pusher 81 (extendable cylinder 81a) are set to be about 13 m / min.

In this way, when the extension speed of the telescopic cylinder 81a is made equal to the traveling speed of the conveyor 82, the quantitative web laminated body Y extruded from the holder 804 side to the conveyor 82 side is transferred onto the conveyor 82. Can be transferred to the normal posture. For example, when the extrusion speed of the quantitative web laminated body Y is faster than the traveling speed of the conveyor 82, when the quantitative web laminated body is placed on the conveyor 82, the lower surface of the quantitative web laminated body and the conveyor 82. A frictional force is generated between the upper surface and the upper surface of the quantitative web laminated body due to a speed difference between the upper surface and the upper surface of the quantitative web laminated body. When it is slow, only the lower side of the quantitative web laminated body placed on the conveyor 82 moves forward rapidly due to the frictional force, and the upper portion of the quantitative web laminated body is inclined rearward. As described above, when the quantitative web laminated body is fed in a state of being inclined (or tilted) forward or backward, the laminated state is collapsed, and for example, as shown in FIG. It causes a trouble that it can not be stored well.

The quantitative web laminated body manufacturing apparatus of the above-described embodiment successively and quantitatively manufactures the quantitative web laminated body Y as follows.

First, in the apparatus shown in FIG. 11, when the original machine driving device 9 is operated, the web feeding device 1, 1, the web cutting device 2, 2, the transfer device 3, 3, and the web folding device 4 are synchronized. Driven. At this time, the current driving speed (signal S ₂ ) is input to the controller 10 by the rotation speed sensor 11 (FIG. 16). Further, when the original machine driving device 9 is operated, continuous webs W and W are continuously fed from the two rolls of raw rolls R and R by the web feeding devices 1 and 1, respectively, as shown in FIG. After the continuous webs W and W were cut into web pieces of a predetermined length by the web cutting devices 2 and 2, respectively, as shown in FIG. Sometimes the web piece WS
A pushing streak WSc (see FIG. 21) is formed at an intermediate position in the traveling direction of. Web pieces WS, W with push bars WSc on each side
As shown in FIG. 14, S is sent between both folding rolls 41, 41 of the web folding device 4 and is sequentially folded there in a zigzag manner. At this time, the lift table 50 is moved up and down by the lift drive device 52 (servo motor 53).
The folding webs, which are continuously or intermittently slightly moved by means of a zigzag, and are folded in a zigzag pattern, are sequentially moved up and down.
0 stacked. At this time, the folding webs that are sequentially folded are neatly aligned because they are guided by the left and right side guides 17, 17 as shown in FIG. Since it is inserted into the annular groove 42 by a predetermined depth, trouble such as paper jamming does not occur.

Then, when a predetermined number of web pieces (for example, 100 pieces on each side and a total of 200 pieces) of web pieces are folded on the lifting table 50, the counter 12 (FIG. 16) for counting them.
The count-up signal (signal S ₁ ) from the controller 1
It is emitted toward 0. Then, as shown in FIG.
Based on the count-up signal, the controller 10 first outputs a signal S ₃ for extending the telescopic cylinder 620 of the first partitioning device 6 and then the locking device 67.
A signal S ₄ is issued to extend the telescopic cylinder 68 of
As shown in FIG. 22, the holding bar 61 is driven from the state indicated by the solid line to the position indicated by the chain line (reference numeral 61 '). At this time,
The presser bar 61a of the presser bar 61 is driven from a position higher than the driving height of the partition bar 71 (the position of reference numeral 71 'in FIG. 23), so the presser bar 61 is opened in a ">" shape. It can be driven with a margin between the upper and lower folding webs. Also, almost at the same time as this pressing bar driving operation,
As shown in FIG. 23, the servo motor 5 of the lifting drive device 52
3 is driven at high speed for a momentary time to rapidly move down the driven presser bar 61 by a small height H (to a height of 61 ', which is slightly lower than the drive height of the partition bar 71). Then, immediately after that, a signal S for extending the telescopic cylinder 720 of the second partition device 7 from the controller 10 is issued.
₅ (FIG. 19) is issued, a signal S ₆ for extending the telescopic cylinder 78 of the locking device 77 is issued, and as shown in FIG. 23, the partition bar 71 changes from the solid line drawing state to the chain line drawing position (reference numeral 71 ′). ).

As shown in FIG. 24, the driving start timings of the presser bar 61 and the partition bar 71, that is, the various operation start signals S _{3 to} S ₆ from the controller 10 are transmitted at an earlier timing as the operating speed becomes faster. Thus, the presser bar 61 and the partition bar 71 can be driven at appropriate timings accordingly. Immediately after the presser bar 61 and the partition bar 71 are respectively driven, the presser bar 61 is moved downward with respect to the elevating table 50 by a slight height as indicated by reference numeral 61 'in FIG. The quantitative web laminated body Y on the lifting table 50 is pressed by the bar 61 '.

After that, the servo motor 53 of the lifting / lowering drive device 52 lowers the lifting / lowering table 50 on which the quantitative web laminated body Y is placed to a discharge height position shown in FIG. 27 at a predetermined speed. Although it is slower than the descending speed of the portion H, it has a speed considerably higher than the free falling speed of the quantitative web laminated body Y by gravity. Immediately after the descent is started, as shown in FIGS. 25 and 26, air A is blown out from the tip of the presser bar 61 by the air blower 13 to suppress the disturbance of the overlapping state of the uppermost web piece WS _1. On the other hand, in the descending stroke of the lifting table 50, the air B is also blown out from the air nozzle 18 provided on the mounting base 761 of the second partitioning device 7 as shown in FIGS. It acts to forcibly converge ₁ on the presser bar 61. Therefore, as described above, the lifting table 5 is moved at a high speed exceeding the free falling speed of the uppermost web folding piece WS _1.
Even if 0 is dropped, the web folding piece WS ₁ does not flicker until the final stage of the descent process, and the laminated state of the quantitative web laminated body Y can be maintained well. In addition, the air blown out from the tip of the presser bar 61 and the air nozzle 18 A, B
Air ions for removing static electricity are mixed in,
The static electricity charged on the web is removed by the air ions in the blown air, so that the web folding piece WS ₁ can be prevented from sticking to the web on the lower surface side.

On the other hand, when the elevating table 50 descends as described above, in the upper portion, as shown in FIG. 27, the temporary receiving device 19 operates and the web laminated body X supported by the partition bar 71 is removed. Support bar 191 of the temporary receiving device 19
Can be replaced on top.

When the elevating table 50 is lowered to the lowermost moving position, as shown in FIG.
As indicated by reference numeral 1 ′, the pressing bar 61 is moved upward by a slight height to release the pressing force applied to the quantitative web laminated body Y by the pressing bar 61. Also at this time, since the air A is blown out from the tip of the pressing bar 61, an air layer is formed between the pressing piece 61a of the pressing bar 61 and the web folding piece WS ₁ . Subsequently, the telescopic cylinder 81a of the pusher 81 is extended, and the quantitative web laminated body Y on the lifting table 50 is discharged by the pushing plate 81b thereof. Since the air layer is formed between the webs, the quantitative web laminated body (particularly, the uppermost web folded piece WS ₁ ) is discharged to the web laminated body processing device 80 side described later without deforming.

As shown in FIG. 29, when the quantitative web laminated body is discharged from the lifting table 50, the lifting drive device 5
2, the empty lifting table 50 is moved upward, and the web laminated body X temporarily held by the temporary receiving device 19 is moved.
Is received by the lifting table 50, and the state shown in FIG. 30 is obtained.

Thereafter, the quantitative web laminated body is continuously manufactured in the same manner.

By the way, in the quantitative web laminated body manufacturing apparatus of the present application, the lifting table 50 is moved by the air blower 13 (air is blown out from the tip of the pressing bar 61).
The uppermost web folding piece WS ₁ of the quantitative web laminated body Y discharged from above is made to be difficult to protrude outward from the side surface (left side surface in the illustrated example) of the quantitative web laminated body. Even if the device 13 is used, there is rarely a possibility that the web-folding piece WS ₁ may protrude outward from the side surface of the quantitative web laminated body. Incidentally, FIG. 31 shows a web laminated body processing apparatus 8 to be described later.
In order to make it easier to understand the action of 0, the web protrusion WS
It is described in a state in which a is exaggerated and largely protruded.
The web protrusion WSa may occur as follows. That is, for example, as shown in FIG. 25, in the case of separating the quantitative web laminated body Y on the lifting table 50 from the subsequent folding web, the respective folded back pieces WS ₁ and WS _{2 of the} upper and lower web pieces to be separated. When the two folded back pieces are in close contact with each other and friction is generated between the folded back pieces, the web folded piece WS ₁ on the quantitative web laminated body Y side is pulled in the upper left direction, and as shown in FIG. blowing air B from the said web folded piece WS ₁ is pushed to the left when it is sprayed onto the upper surface of the web folded piece WS _1, further web folded piece WS ₁ is joined onto the pressing piece 61a of the presser bar 61 In this case, the pusher 81 exerts such an action that the web folding piece S ₁ remains on the left side when the quantitative web laminated body on the lifting table 50 is extruded. Thus, when the pulling force in the left direction relative to the web folded piece WS ₁ (or urging force) acts, the web folded piece WS ₁ to the uppermost is displaced to the left relative quantification web laminate Y Web protruding part W
There is a possibility that Sa will occur.

As described above, when the quantitative web laminated body Y is packed in a box as shown in FIG. 38 with the web protruding portion WSa, the web protruding portion WSa collides with the side wall of the box B and cannot be stored neatly. There is a problem, and the quantitative web laminated body manufacturing apparatus of this embodiment is provided with a web laminated body processing apparatus 80 for treating the web protruding portion WSa (folding to the quantitative web laminated body side).

This web laminated body processing apparatus 80 is shown in FIG.
As shown in FIG. 37, a holding body 8 for holding the quantitative web laminated body Y extruded from above the lifting table 50 at a position in the vicinity of a side portion of the lifting table 50 that has moved down to the discharge position.
04, a rotation device 806 for rotating the holder 804 by 180 ° in the vertical plane per operation, and the quantitative web laminated body Y from the holder 804 side to the conveyor 82.
A folding device 808 is provided which folds the holding body 804 upside down and folds down the web protruding portion WSa located at the bottom of the quantitative web laminated body Y while being extruded to the side.

The holder 804 is composed of two upper and lower holding plates 84.
It has 1,841. These holding plates 841 and 841
Has two end portions (a direction perpendicular to the paper surface) of the front and rear plates (circular plates) 842 respectively.
The guides 843 and 843 of the book are attached so as to be movable in the approaching and separating directions. Also, this holding body 804 is
The front and rear plates 842 are rotatably supported in the vertical plane by axially supporting the shafts at the central portions of the outer surfaces thereof.

Each of the holding plates 841 and 841 can be operated in an approaching / separating direction with respect to each other by opening / closing devices 805 provided on the front and rear sides. Each opening / closing device 805
Has a pair of left and right telescopic cylinders 851 and 851, respectively. Each of these telescopic cylinders (there are 4 in total) 85
1, 851 expand and contract at the same time and in opposite directions, and when they are extended, the holding plates 841 and 841 are separated from each other by a range slightly larger than the thickness of the quantitative web laminated body Y, and conversely, when they are reduced, the holding plates 841 and 841 are held.
