Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is one in which a web laminate used as, for example, a box-type tissue paper is transferred to the packaging process side in a state where it is separated by a fixed amount, and the quantitative web laminate is stabilized. The present invention relates to a web laminated body processing method and a web laminated body processing apparatus which are transported in the above state and facilitate the treatment on the packaging process side.

[0002]

2. Description of the Related Art A web laminate such as a boxed tissue is generally manufactured by using a web laminate manufacturing apparatus as shown in FIG. That is, in the conventional web laminated body manufacturing apparatus shown in FIG. 1, the wide continuous webs W, W respectively fed from the two original rolls are divided into product widths by the slitters 11, 11 (wide widths). After forming into a web laminated body, it may be divided into product widths), and the divided continuous web on each side is divided into 2 pieces.
The product length is cut through the two blade rolls 12, 13 and the web pieces S, S on the left and right sides are cut by the relay rolls 14,
14 through a pair of folding rolls 15 and 15,
Therefore, the folding bars 16 and 16 are sequentially folded in a zigzag shape, and the folded folding webs are sequentially stacked and guided through a guide (not shown) onto the table 121. In the case of the web laminated body manufacturing apparatus shown in FIG. 1, the web laminated body is sent out on the table 121 in a continuous state (state indicated by reference numeral X). Then, the continuous web laminated body X sent out onto the table 121 has a fixed amount of the web laminated body Y when an operator looks at the division mark attached to the continuous web laminated body X for each unit of product.
Then, the quantitative web laminated body Y is placed on the starting end portion 7a of the conveyer 7 and transferred to the packaging (boxing) step side. In the packaging process, as shown in FIG. 2, the quantitative web laminated body Y transferred by the conveyor 7.
Are sequentially stored in the paper box B to be a final product. In this packaging process, the quantitative web laminated body is put into the paper box B which is in a standby state with the insertion opening Ba opened by a pushing device (not shown). Y is pushed in from the longitudinal direction.

In a web laminated body manufactured by this type of web laminated body manufacturing apparatus (for example, in FIG. 1), each web piece S, S, ... Is simply folded in a zigzag shape, so Since air is present between the folded webs thus formed, the volume of the quantitative web laminate Y is high, and the joining force between the vertically adjacent web pieces S, S is very weak. There is.

[0004]

By the way, in the prior art,
The web laminated body X manufactured by the web laminated body manufacturing apparatus is separated into a fixed amount of the web laminated body Y, and the quantitative web laminated body Y is placed on the transport conveyor 7 as it is and transferred to the installation position of the boxing device. However, since the quantitative web laminated body Y is transferred on the conveyor 7 with the bonding force between the vertically adjacent web pieces S, S being very weak, the quantitative web laminated body Y is transferred during the transfer. The web piece Y on the upper portion of the quantitative web laminated body Y is indicated by the reference numeral S'in FIG. 1 and FIG. 2 because the wind is blown from the outside to the web laminated body Y or the wind is influenced by the transfer speed of the conveyor 7. Like that. In this way, when the upper web piece is turned up greatly as indicated by the reference sign S ', the turned-up web piece S'collides with the edge of the insertion opening Ba of the paper box B during the boxing work, and the storing operation is performed. If it does not work well, or if the top-turned web piece S'is forced into the paper box, it will be stored in a wrinkled state (in that case, there will be a problem with the quality of the manufactured product. Occurs).

In the conventional quantitative web laminated body Y, in order to avoid such a problem (problem due to turning of the upper web piece S at the time of transfer), the quantitative web is transferred during the transfer to the boxing machine side. A device for preventing the wind from hitting the laminated body Y (for example, a wind guard is provided), or a quantitative web laminated body Y for the boxing device side
It is necessary to slow down the transfer speed of
As described above, in order to prevent the quantitative web laminated body Y from being exposed to the wind from the outside (for example, to provide a windbreak guard), the facility cost is required, and when the transfer speed is slowed, the transfer efficiency to the box packing device side becomes low. There's a problem. Further, the paper box B for accommodating the quantitative web laminated body Y is formed with an inner diameter slightly larger than the bulk H of the quantitative web laminated body Y in the natural state in order to make it as compact as possible. Then, when the paper box B is formed in a closed state at the standby position, the width of the vertical space in the paper box B becomes small, and the quantitative web laminated body Y may not be stored properly. .

In view of the above-mentioned conventional problems, the present invention prevents the upper web piece from being easily flipped over by the influence of wind when the quantitative web laminate is transferred to the packaging (boxing) step side. It is an object of the present invention to propose a web laminated body processing method and a web laminated body processing apparatus which facilitate the packaging work of the quantitative web laminated body.

It is characterized in that it is provided with a transfer conveyor for transferring to the packaging step side, and provided with a compression device for compressing the quantitative web stack in the web stacking direction at the start end side of the transfer conveyor.

In the web laminated body processing apparatus according to the present invention, the compression device may be provided on the starting end portion of the conveyer to directly compress the quantitative web laminated body on the starting end portion of the conveyer. It is also possible to provide the compressed quantitative web laminate provided in the vicinity of the starting end of the conveyor on the starting end of the conveyor. Further, as the compressing device, a device having an appropriate structure can be adopted as long as it can compress the quantitative web laminated body from the laminating direction.

[0011]

In the method for treating a web laminate according to the present invention, the quantitative web laminate is compressed in the web laminating direction.
Air between each web piece of the quantitative web stack is eliminated,
The volume of the quantitative web laminated body becomes low, and the joining force between vertically adjacent web pieces becomes large. Therefore, the quantitative web laminate can be transported on the transport conveyor in a low bulk state and in a state where the joining force between the web pieces is large.

Further, in the web laminated body processing apparatus of the present invention, the quantitative web laminated body can be placed on the starting end portion of the conveyer in a state of being compressed in the web laminating direction by the compression device. The body can be transferred to the packaging process side while being compressed.

[0013]

According to the web laminated body processing method and the web laminated body processing apparatus of the present invention, the quantitative conveyor web laminated body is compressed in the web laminating direction, and air is removed between the web pieces to convey the conveyor. Since it is placed on the starting end of the sheet, the quantitative web laminate can be transferred on the conveyor while the bulk of the laminate is low and the joining force between the web pieces is high. Therefore, during the transfer of the quantitative web laminated body, the web pieces are not easily turned over even if the quantitative web laminated body receives wind.
It can be transferred to the installation position of the packaging device in a stable state. That is, there is an effect that it is not necessary to provide a special windproof guard on the transfer conveyor, and the transfer speed of the transfer conveyor can be increased to improve transfer efficiency. In addition, by reducing the bulk of the quantitative web laminate by compression, the quantitative web laminate is less likely to collide with the edge of the insertion port of the packaging container (paper box) during packaging (boxing) work, and the packaging work is reliable and easy. There is an effect that can be done.

EXAMPLES Some examples of the present invention will be described below with reference to FIGS. 3 to 20. FIGS. 3 to 4 show a first example, and FIGS. 5 to 19 show a second example. FIG. 20 shows the web laminated body processing apparatus of the third embodiment. Incidentally, FIG.
In the web laminated body processing apparatus of the first embodiment shown in FIG. 4, the web laminated body X is installed adjacent to the web laminated body manufacturing apparatus on the fixed table 121 so that the web laminated body X is continuously manufactured. 5 to 19 and the third embodiment of FIG. 20, the quantitative web laminated body Y is automatically separated each time a fixed amount of the web laminated body Y is folded on the lifting table 21. It is continuously installed in the quantitative web laminated body manufacturing apparatus.

In the first embodiment shown in FIG. 3, the same web laminated body manufacturing apparatus as the conventional example shown in FIG. 1 is adopted. That is, the web laminated body manufacturing apparatus of FIG. 3 divides the wide continuous webs W and W respectively fed from the two series of original rolls into product widths by the slitters 11 and 11, respectively, and then divides the continuous webs on each side thereof. The web is cut between the two tool rolls 12 and 13 into product lengths,
The web pieces S, S on each of the left and right sides are connected to the relay rolls 14, 14
Through the pair of folding rolls 15 and 15 and sequentially fold each other in zigzag by the folding bars 16 and 16, and the folded folding webs are sequentially laminated in a guide (not shown). It is designed to be guided onto the fixed table 121. Then, the continuous web laminated body X sent out onto the fixed table 121 is divided into a fixed amount of web laminated body Y by an operator by looking at the division mark attached to the continuous web laminated body X for each unit quantity of the product. By placing the separated quantitative web laminated body Y on the starting end portion 7a of the conveyor 7 installed adjacent to the fixed table 121, the quantitative web laminated body Y is automatically packed (boxed) on the process side. Can be transferred to. In the fixed-quantity web laminated body Y, which is separated from the continuous web laminated body X on the fixed table 121, a large amount of air is present between the web pieces S, S, and the bulk in the web laminating direction becomes large. In addition, the joining force between the web pieces S and S that are vertically adjacent to each other is very weak.

Further, in the first embodiment shown in FIG. 3, as the conveyor 7, two front and rear conveyors, which are a relatively short front conveyor 71 and a long rear conveyor 72, are arranged in series. The front conveyor 71 is a part of the compression device 50, which will be described later, and it is desirable to run the front conveyor 71 at a speed that is not so fast in order to ensure the compression action. Also, the traveling speed of the rear conveyor 72 is considerably faster than the traveling speed of the front conveyor 71,
The transfer speed of the quantitative web laminated body Y to the packaging process side is increased. Incidentally, in another embodiment, the conveyor 7 is
It is also possible to use one common conveyor.

In the first embodiment shown in FIG. 3, a compression device 50 for compressing the quantitative web laminated body Y is provided on the starting end side 7a of the conveyor 7. The compressing device 50 of the first embodiment is composed of a front conveyor 71 and a holding conveyor 73 installed above the front conveyor 71. The height of the transfer passage 74 between the front conveyor 71 and the pressing conveyor 73 is set so as to gradually decrease (narrow) from the inlet side toward the outlet side. That is, the inlet side of the transfer passage 74 is opened to be considerably larger (higher) than the height H of the quantitative web laminated body Y in the as-folded state, and the height of the transfer passage 74 increases as it goes to the outlet side. Is gradually reduced, and the opening height is set to about 2/3 of the height H of the quantitative web laminated body Y before compression at the outlet portion.

The starting end of the pressing conveyor 73 is slightly retracted from the starting end of the front conveyor 71.
The quantitative web laminated body Y is easily placed on the starting end portion of No. 1. Further, the front conveyor 71 and the pressing conveyor 73 are designed to run at a constant speed with respect to each other.

The web laminated body treating apparatus of the first embodiment shown in FIG. 3 operates as follows. That is, on the side of the web laminated body manufacturing apparatus, the web laminated body X is continuously fed onto the fixed table 121, but a fixed amount of the web laminated body Y is separated from the continuous web laminated body X, and the quantitative web laminating is performed. The body Y is supplied to the inlet side of the compression device 50 (on the starting end of the front conveyor 71). Then, the quantitative web laminated body Y is compressed between the front side conveyor 71 and the pressing conveyer 73 as the front side conveyor 71 feeds the same. Then, when the quantitative web laminated body Y is sent out from the outlet of the compression device 50, the compressed quantitative web laminated body Y is transferred onto the starting end portion of the rear conveyor 72. The compressed fixed-quantity web laminate Y that has passed through the compression device 50 and has been transferred onto the starting end portion of the rear conveyor 72.
Means that the air present between the web pieces S, S is eliminated and the bulk of the quantitative web laminated body Y is reduced (reference numeral H ₁ ), and the bonding force between the upper and lower web pieces S, S is increased. It is getting bigger. Therefore, even if air is blown to the fixed quantitative web laminate Y while the compressed quantitative web laminate Y is being transferred on the rear conveyor 72, the joining force between the web pieces S, S is increased. As a result, the web pieces S are less likely to be turned over, and can be transported in a stable state. Further, when the web pieces S become difficult to turn over during the transfer of the quantitative web laminated body Y in this way, the traveling speed of the transport conveyor 7 (rear side conveyor 72) is increased to increase the transfer speed of the quantitative web laminated body Y. It is possible to improve the transfer efficiency. When the transfer speed is increased in this way, the quantitative web laminated body Y receives wind resistance, but since the joining force between the web pieces S, S is increased due to the compression, the web piece S is turned over. Hateful. Further, since the volume of the quantitative web laminated body Y is lowered by the compression, as shown in FIG. 4, the quantitative web laminated body Y during the packaging (boxing) work.
Is less likely to collide with the edge of the insertion opening Ba of the paper box B, so that the packaging work can be performed reliably and easily.

The web laminated body processing apparatus of the second embodiment shown in FIGS. 5 to 19 automatically quantifies a fixed amount of the web laminated body Y from a subsequent folded web each time a predetermined amount of the web laminated body is folded. It is continuously installed in the quantitative web laminated body manufacturing apparatus which is designed to be separated. That is, in the second embodiment, the quantitative web laminated body manufacturing apparatus sequentially manufactures the web laminated bodies Y by a predetermined amount while separating them.
The separated quantitative web laminated body Y is automatically compressed by the compression device 5
0, and after compressing there, the compressed quantitative web laminated body Y is automatically sent out to the conveyor 7 side, and the quantitative web laminated body Y is folded from the folded web.
All the work up to the box packaging is done automatically. Further, in the web laminated body processing apparatus of the second embodiment, in order to efficiently process the protruding portion Sa of the uppermost web piece S of the quantitative web laminated body Y, which occurs in the quantitative web laminated body manufacturing apparatus of this type. It also serves as a web protrusion processing device. Hereinafter, the second embodiment will be described in detail.

The quantitative web laminated body manufacturing apparatus (FIGS. 5 to 9) used in the second embodiment is known (for example, as a document of a similar technique, there is US Pat. No. 4,874,158). This quantitative web laminated body manufacturing apparatus comprises a web folding device 1 for continuously folding left and right web pieces S, S in a zigzag shape, and a web for separating a web laminated body laminated on an elevating table 21 by a predetermined amount. The laminated body separating device 2 is provided so that the quantitative web laminated body Y can be successively manufactured.

That is, as shown in FIG. 5, the wide continuous webs W, W respectively fed from the two rolls of original rolls.
Are divided into product widths by slitters 11 and 11, respectively, and the divided continuous webs on the respective sides are cut between the two cutter rolls 12 and 13 into product lengths, and web pieces S and S on the left and right sides thereof are cut. Is guided between the pair of folding rolls 15 and 15 via the relay rolls 14 and 14, and is sequentially folded into zigzags by the folding bars 16 and 16, and the folded folding web is folded into the double folding rolls 15 and 15.
A web laminated body is formed by sequentially laminating it on an elevating table 21 provided in the lower part of the space 15. The lifting table 21 has a stack of webs formed on top of it.
As the amount is increased, it is finely moved down by the lifting drive device 22.

Then, the web piece S is placed on the lifting table 21.
When a predetermined number of sheets (for example, 200 pairs) are folded, a count-up signal is issued, and the signal causes the count of FIG.
As shown in FIG. 23, the expansion / contraction cylinder 24 expands and the holding bar standing by at the position of reference numeral 23 ′ is 1
It is inserted into one folding web piece S and presses the upper surface of a certain amount of the web laminated body Y, and subsequently, as shown in FIG. 7, the partition bar 25 at the opposite position continues from the opposite side by another telescopic cylinder 26. It is inserted into the folding web piece S.
The upper side of the presser bar 23 has such a length that it does not reach the folding portion of the folded web piece S when it is inserted into the folded web piece S. I try not to damage it. Further, after the partition bar 25 is inserted into the folding web, the partition bar 25 is also operated in association with the web half-folding operation to move up and down the driving device 27.
A slight movement is made to drop.

Next, as shown in FIG.
Moves at a high speed together with the presser bar 23 with the quantitative web laminated body Y placed thereon, and is supported by the web piece (symbol S ₁ ) on the uppermost part of the quantitative web laminated body Y on the lifting table 21 side and the partition bar 25 side. The following folded web is separated from the bottommost web piece (reference S ₂ ). At this time, the uppermost web piece S ₁ on the lifting table 21 side is pulled in the direction of arrow a, and the folded portion Sc on the web piece S ₁ side is pulled.
Will be pulled to the left side in FIG. Therefore, when the two web pieces S ₁ and S ₂ are completely separated from each other, as shown in FIG. 9, the leading end portion (reference numeral Sa) of the uppermost web piece S ₁ on the lifting table 21 side is the fixed web laminated body Y. It slightly protrudes outward from the side surface Ya in the horizontal direction.

Thereafter, as shown in FIG. 9, in the lifting table 21, the pressing bar 23 keeps pressing the upper portion of the quantitative web laminated body Y (the upper half area S _{1 of the} uppermost web piece S).
Is coated on the presser bar 23) and is lowered to the extrusion height of the quantitative web laminated body Y (the installation height of the extrusion device 3). Then, the presser bar 23 retreats to the left side as indicated by the reference numeral 23 'in FIG. 9, and the web piece S ₁ placed on the upper part of the presser bar 23 at that time moves to the left side as the presser bar 23 moves backward. When the web piece S ₁ is pulled, the tip end portion Sa of the web piece S ₁ protrudes outward from the left side surface Ya of the quantitative web laminated body Y by a considerably large width (for example, about 20 to 30 mm).

When the presser bar 23 retracts, the telescopic cylinder 31 of the pushing device 3 extends, as shown in FIG.
The pressing plate 32 pushes out the quantitative web laminated body Y on the lifting table 21 to the compression device 50 side (holding body 4 side),
Further, after being compressed by the compression device 50 as described later, the compressed quantitative web laminated body Y is conveyed by the conveyor 7.
It is sent to the top and transferred to the packaging process side. Further, after that, the telescopic cylinder 31 of the extruding device 3 is contracted, the empty lifting table 21 is moved upward, and the web laminated body folded on the partition bar 25 is lifted from the partition bar 25. The quantitative web laminated body Y is continuously manufactured in the same manner as above by receiving the folding operation without interrupting the folding operation. Immediately before the web laminated body temporarily supported on the partition bar 25 is transferred onto the lifting table 21, the lowermost web piece on the partition bar 25 side (shown by symbol S ₂ in FIG. 8) is folded. The bending device performs an operation of bending it into an S shape, and thereafter, the lifting table 21.
The lowermost web piece is placed on the top in a folded state as indicated by reference numeral Sd (FIG. 8). The folding device for forming the folded-back portion Sd is not shown in the drawings because it has nothing to do with the gist of the present invention (for details, see US Pat. No. 4,874,158).

The quantitative web laminated body Y thus manufactured is stored in the paper box B by the packaging device at the rear end side of the conveyor 7 to be the final product. The edge is largely protruded to the outside of the side surface Ya of the quantitative web laminated body Y (the web protruding portion S
When the box is packed in the a) state, there is a problem in that quality problems remain, and when the web is stored in the paper box B with the protruding portion Sa, the protruding portion Sa is inserted into the paper box B. The uppermost web piece may be turned over by colliding with the edge of the mouth Ba, or the web protruding portion Sa may be forcibly pushed into the paper box and stored in a wrinkled state (quality).

When the rotation of the holder 4 is completed, the telescopic cylinders 51, 51 of the opening / closing device 5 extend as shown in FIG. 15, and the holding plates 41, 41 release the sandwiching force of the quantitative web laminated body Y. In this state (state of FIG. 15), the web protruding portion Sa of the quantitative web laminated body Y is located on the lower surface side. In this state, both holding plates 41, 41
Even when is opened up and down, the quantitative web laminated body Y is maintained in a substantially compressed posture without being stretched so much because the air between the folding webs is removed when compressed (FIG. 16). and remains is compressed by a height H ₂ between the quantitative web laminate Y prior to compression as shown in).

Next, as shown in FIG. 16, the elevating table 21 on which the next fixed amount web laminated body Y is placed descends to the pushing position. At that time, the arm 82 of the folding device 8 moves downward and the stopper 86 is opened. It comes to stand by at the positioning position.

Then, as shown in FIG. 17, the telescopic cylinder 31 of the pushing device 3 is extended by the first stage, and the pushing plate 32 pushes the quantitative web laminated body Y on the lifting table 21 to the holding body 4 side. As a result, the quantitative web laminated body Y on the holding body 4 side is pressed in a bead shape, and the quantitative web laminated body Y pressed in the bead shape is provided with the stopper 8 at the front side surface thereof.
6 is advanced until it abuts (or approaches) 6. At this time, the web protruding portion Sa located on the lower surface side of the leading side quantitative web laminated body Y is located above the small interval T between the rear edge 41a of the lower holding plate 41 and the front edge 7a of the conveyor 7. Come to be located. Immediately after that, high-pressure air is blown out from the nozzle 84, and the web protruding portion Sa has a symbol S.
After being folded into the small space T as indicated by a'and subsequently the arm 82 is retracted upward as indicated by reference numeral 82 ', FIG.
As shown in FIG. 8, the telescopic cylinder 31 of the pushing device 3 is the second
The fixed-quantity web laminated body Y on the leading side is transferred onto the conveyor 7 after being extended in stages. At this time, the web protruding portion Sa ′ (FIG. 17) folded in the small interval T is fixed by the quantitative web stacking as shown by the reference symbol Sb in FIG. 18 when the quantitative web laminated body Y is pushed out onto the conveyor 7. It is automatically folded on the bottom side of body Y.

The fixed-quantity web laminate Y transferred onto the transport conveyor 7 is moved to the packaging process side by the transport conveyor 7 traveling with the web protruding portion being folded as shown by the symbol Sb. It is transported and automatically packed therein as shown in FIG. While the quantitative web laminated body Y is being conveyed, the folding web (particularly, the uppermost web piece S) is agitated due to its speed, but the quantitative web laminated body Y is conveyed in a compressed state. As a result, the web pieces will not turn over (or become harder to turn over) due to the wind swirling action.

As described above, according to the web laminated body processing apparatus of the second embodiment, the web protruding portion Sa of the quantitative web laminated body Y can be automatically folded to the lower surface side of the quantitative web laminated body Y. The quantitative web laminated body Y of good quality can be automatically manufactured, and since the quantitative web laminated body Y has no protruding portion at the time of boxing, the boxing work can be performed smoothly. Further, since the quantitative web laminated body Y is supplied to the boxing process side in a compressed state, the volume of the quantitative web laminated body Y is reduced and the boxing work can be performed more easily.

The third embodiment shown in FIG. 20 is an assembly of the quantitative web laminated body manufacturing apparatus shown in FIG. 5 with the web laminated body processing apparatus of the first embodiment shown in FIG. That is, in the third embodiment, the quantitative web laminated body Y is sequentially and automatically manufactured by the quantitative web laminated body manufacturing apparatus, and
At the position where the lifting table 21 is moved downward, the pushing device 3
(In the case of this embodiment, the one-stage expansion / contraction may be used) to extrude the quantitative web laminated body Y on the lifting table onto the starting end portion 7a of the front conveyor 71 of the compression device 50, and then to carry out the quantitative web laminated body Y. Front conveyor 71 and presser conveyor 7
After being compressed by 3 and 3, it is sent to the side of the rear conveyor 72, and the fixed quantitative web laminated body Y is packed in a box by a packaging device on the terminal side of the rear conveyor 72. In the third embodiment, although some of the uppermost web pieces in the quantitative web laminate Y may be boxed in a state of protruding from the side surface of the quantitative web laminate Y, All processes from manufacturing to packaging are automatically performed continuously.
