Has been. The first and second stacking parts 6a and 6b are formed in a mesh shape and have air permeability. Such a mesh is formed by subjecting a metal or resin plate to physical processing such as punching or chemical processing such as etching. The pore diameter of the mesh is in the range of 0.01 mm to 2 mm, and the ratio of the pore area to the total suction area (opening ratio) is in the range of 10% to 80%. Conditions such as the mesh pore diameter and the aperture ratio are appropriately selected according to the material to be laminated, the thickness, and the like.

As shown in FIGS. 1 to 3, the first accumulation unit 6 a is configured to suck the first absorbent material from the first shooter 4 by the first intake mechanism 7. The first intake mechanism 7 includes a second rotating drum 7a that rotates in synchronization with the first rotating drum 3, a radial duct 7b that extends radially from the second rotating drum 7a and is connected to the first stacking unit 6a. It is composed of a fixed shaft duct 17. The second rotating drum 7 a and the radiation duct 7 b are integrated with the first rotating drum 3.
The second rotating drum 7 a is formed in a hollow cylindrical shape, and is disposed so as to be coaxial with the inner cylindrical portion 2 b of the fixed drum 2. The radiation duct 7b is formed in the shape of a hollow pipe and is connected to the first stacking portion 6a via a suction box 7c (see FIG. 3) disposed on the lower surface of the first stacking portion 6a. The stacking unit 6a and the second rotating drum 7a are communicated with each other.
As shown in FIG. 2, partition walls 18 and 19 are provided on the outer surface of the fixed shaft duct 17 so as to extend radially toward the inner surface of the second rotating drum 7a. An opening (not shown) is formed in a predetermined region (corresponding to the first supply region α + the suction region γ) on the outer surface of the fixed shaft duct 17 defined by the partition walls 18 and 19. The space portion formed between the inner surface of the second rotating drum 7a and the outer surface of the fixed shaft duct 17 communicates with the space. The fixed shaft duct 17 is connected to a first vacuum pump (not shown) together with the second rotating drum 7a.

Such a first intake mechanism 7 sucks the first absorbent material into the first accumulation portion 6a at an arbitrary position of the fixed drum 2 as the first rotary drum 3 rotates by the intake of the first vacuum pump. It is supposed to let you.
The first vacuum pump has a capability of a static wind pressure of −40 to −5 kPa, and in this range, negative pressure in the first intake mechanism 7 (for example, negative pressure in the first accumulation unit 6a and the second rotary drum 7a) is − It is preferable to set to 20 to -1 kPa.
Here, an opening 16 extending in the circumferential direction is formed on the outer peripheral surface of the first rotating drum 3 in the first supply region α. The opening 16 opens the first stacking portion 6a and shields the second stacking portion 6b, so that the first absorbent material does not enter the second stacking portion 6b, and the first absorbent material, the second absorbent material, It has a function to prevent mixing.

  The second accumulation unit 6b is configured to suck the second absorbent material from the second shooter 5 by the second intake mechanism 8. The second air intake mechanism 8 is configured such that the suction chamber 15 partitioned by the partition walls 13a and 13b in the space between the outer cylindrical portion 2a and the inner cylindrical portion 2b of the fixed drum 2 is transferred from the inner cylindrical portion 2b to the second vacuum pump. (It is not shown) It is comprised so that it may inhale and may make a negative pressure. The suction chamber 15 extends on the outer peripheral surface of the fixed drum 2 over the suction region γ (in the range of about −90 ° to about 135 °) excluding the first supply region α and including the second supply region β. The side surface of the inner cylindrical portion 2b is formed with an opening in the suction chamber 15, and communicates with the second stacking portion 6b.

Such a second intake mechanism 8 is configured to cause the second collection portion 6b to suck the second absorbent material in the suction region γ of the fixed drum 2 by the suction of the second vacuum pump. Note that the second intake mechanism 8 operates constantly and acts on the second accumulation portion 6b of the two-layer accumulation member 6 that passes over the second supply region β.
The second vacuum pump has a capability of a static wind pressure of −40 to −5 kPa, and within this range, the negative pressure in the second intake mechanism 8 (for example, the negative pressure in the second accumulation unit 6 b and the fixed drum 2) is −20 to 20. It is preferable to set to −1 kPa.
In FIGS. 1 and 2, in order to explain the inside of the apparatus, the fixed drum 2, the first rotating drum 3 and the second rotating drum 7 a are shown in an opened state. A cover is attached to prevent outflow of air and particles during suction.

Next, opening / closing of intake air of the first intake mechanism 7 will be described.
As shown in FIG. 2, first, the angle ε is an angle (about 45 °) between the partition wall 18 and the partition wall 19 for the fixed shaft duct 17, and the partition wall 13b and the partition wall 14 for the second rotating drum 7a. The angle between In the range of this angle ε, there is no opening portion on the surface of the fixed shaft duct 17, no suction by the first vacuum pump, and no fiber supply from the first shooter 4. .
Since the conveyor 12 is sucking negative pressure, the absorbent laminate 10 should be separated from the first and second stacking parts 6a and 6b by its own gravity in the range of the angle ε. Since it is sucked by the first vacuum pump until just before, it is difficult to detach from the first and second stacking parts 6a and 6b.
Therefore, it is necessary to forcibly separate the absorbent laminate 10 from the first and second stacking parts 6 a and 6 b by the transfer blow 20. The transfer blow 20 uses exhaust air from a general blower (not shown). The absorbent laminate 10 separated by the transfer blow 20 is sucked and conveyed on the conveyor 12, and proceeds to the next process.
On the other hand, electromagnetic valves (not shown) are respectively attached to the radiation ducts 7b. The electromagnetic valve is configured to open and close the radiation duct 7b by a remote switch (not shown) installed at a predetermined position of the fixed drum 2 as the first rotating drum 3 rotates. Specifically, in the first supply region α and the suction region γ (including the second supply region β), the electromagnetic valve opens the radiation duct 7b to bring the first accumulation portion 6a into a negative pressure state, and the idle region ε At (angle ε: a range of about 225 ° to about 270 °), the radiation duct 7b is closed to bring the first stacking portion 6a into an atmospheric pressure (or positive pressure) state.

Next, the most preferable embodiment of the fiber stacking method of the fiber stack of the present invention will be described in detail together with the operation of the fiber stacking apparatus 1 of the above embodiment.
In the fiber stacking method of the present invention, when forming a laminated body in which n stacking fiber patterns are stacked from two or more kinds of raw materials, a multilayer integrated member that becomes a multilayer from n integrated portions is used. In this embodiment, the first and second absorbent materials may be stacked by sequentially stacking the first stacked fiber pattern, the second stacked fiber pattern, and the nth stacked fiber pattern. The fiber stacking method for forming the absorbent laminate 10 in which two (n = 2) first and second absorbent laminates 10a and 10b are laminated will be described.
The fiber stacking method of the present embodiment includes a first step and a second step shown below. The first and second steps are performed during one rotation of the first rotating drum 3.

  In the first step, the first absorbent material is supplied from the first shooter 4 to the first supply region α of the fixed drum 2, and at this time, in the two-layer integrated member 6 located in the first supply region α, Only the first first accumulation portion 6a from the lower layer is brought into a negative pressure state by the intake mechanism 7, and the first absorbent material 10a is formed on the first accumulation portion 6a by stacking the first absorbent material. To do.

  In this case, in the first supply region α, only the first accumulation unit 6a is open and in a negative pressure state, and therefore the first absorbent material is accumulated only in the first accumulation unit 6a, and the second accumulation is performed. It does not enter the part 6b and is not mixed with the second absorbent material in the second step.

  In the second step, the second absorbent material is supplied from the second shooter 5 to the second supply region β of the fixed drum 2, and at this time, in the two-layer integrated member 6 located in the second supply region β, Only the second second stacking portion 6b (excluding the portion corresponding to the first stacking portion 6a) from the lower layer is brought into a negative pressure state by the intake mechanism 8, and the first intake mechanism 7 allows the second stacking portion 6b to Only the portion corresponding to the first accumulation unit 6a is in a negative pressure state (that is, the entire second accumulation unit 6b is in a negative pressure state by the first and second intake mechanisms 7 and 8). Then, the second absorbent material is stacked and the second absorbent stacked body 10b is stacked on the upper layer of the first absorbent stacked body 10a to form the absorbent stacked body 10.

  In this case, in the second supply region β, since both the first and second intake mechanisms 7 and 8 are operated for suction, the second stacking unit 6b is the upper portion of the first stacking unit 6a. The second absorbent material is sucked into the negative pressure state through the absorbent multifilament 10a, and the second absorbent material is sucked into the negative pressure state at a portion other than the upper portion of the first stacking portion 6a. Yes.

In the subsequent steps, as the first rotating drum 3 rotates, the first and second intake mechanisms 7 and 8 are positioned if the two-layer stacking member 6 is positioned in the suction region γ even if it is out of the second supply region β. Since both of them are operated by suction, the absorbent laminate 10 is sucked and held in the two-layer assembly member 6.
When the two-layer integrated member 6 is located in the idle region ε, the two-layer integrated member 6 is theoretically in an atmospheric pressure (or positive pressure) state, and the absorbent laminate 10 has a centrifugal force acting on this, Due to its own weight and the transfer blow 20, it is separated from the two-layer stacking member 6 and placed on the mount sheet 11 on the conveyor 12. In this case, the detached absorbent laminate 10 can be more reliably detached from the two-layer stacking member 6 by separately providing a suction mechanism (not shown) below the conveyor 16.
The above-described series of steps is repeated with the rotation of the rotating drum 3, whereby the absorbent laminate 10 is intermittently disposed on the mount sheet 11.

  As described above, according to the present embodiment, the two-layer stacking member 6 having a multilayer shape from the first and second stacking sections 6a and 6b is disposed on the rotary drum 3, and the first and second stacking sections are arranged. 6a and 6b are made to be in a negative pressure state independently by the first and second intake mechanisms 7 and 8, respectively, so that a large capital investment is not required and only the first rotating drum 3 is different from each other. The second absorbent material can be laminated with different first and second stacking patterns while being sufficiently sucked without being mixed with each other.

  Further, according to the present embodiment, the first suction mechanism 7 is configured such that the shaft drum 7a and the radiation duct 7b are integrated with the rotary drum 3, so that the first stacking portion of the two-layer stacking member 6 that is rotating and moving is used. 6a can be made into a negative pressure state independently.

  Furthermore, according to the present embodiment, since the first intake mechanism 7 is inhaled in at least the first supply region α and the second supply region β, the first absorbent material is added in the first supply region α. The mixing of the first and second absorbent materials is prevented without entering the second accumulating portion 6b, and in the second supply area β, the second air intake mechanism 8 does not act in the second accumulating portion 6b. The second absorbent material can be sufficiently sucked even in the upper portion. In particular, in the first supply region α, the outer peripheral surface of the fixed drum 2 is opened so as to open the first stacking portion 6a and shield the second stacking portion 6b, so that the first and second absorbent materials are mixed. It can be prevented more effectively.

  Furthermore, according to the present embodiment, the second intake mechanism 8 is configured such that the internal pressure of the fixed drum 2 is negative in the suction area γ excluding the first supply area α and including the second supply area β. Therefore, in the second supply region β, the suction region γ can be independently brought into a negative pressure state with respect to the second stacking portion 6b of the two-layer stacking member 6 that passes therethrough, and the second supply region β is removed. Then, in combination with the action of the first intake mechanism 7, the first and second absorbent fibers 10a and 10b can be sucked and held.

The present invention is not limited to the above-described embodiment, and various changes can be made.
In the fiber stacking apparatus of the present invention, the first vacuum pump and the second vacuum pump and two vacuum pumps are used, but fiber stacking can also be performed by one vacuum pump.
Moreover, when the stacking method of the present invention forms a laminate in which n stacking patterns are stacked from two or more kinds of raw materials, a multilayer integrated member that becomes a multilayer from n integrated portions is used. While rotating this multilayer stacking member, the kth k-th stacking portion from the lower layer is sucked into the kth stacking portion to suck the i-th raw material to form the kth pile fiber pattern, and the (k + 1) th (k + 1) th (k + 1) th step from the lower layer ) With respect to the (k + 1) -th process in which the j-th raw material different from the i-th raw material is sucked into the accumulation portion to form the (k + 1) -th fiber pattern on the upper layer of the k-th fiber pattern, k is changed from 1 to (n− You may make it comprise 1st process-nth process by incrementing to 1).
In this case, the first intake mechanism may be applied to the first to mth accumulation units, and the second intake mechanism may be applied to the (m + 1) th to nth accumulation units. Any one of the first intake mechanism and the second intake mechanism may be applied to all of the accumulation units. In the fiber stacking method of the present invention, the number n of the fiber stack patterns is not particularly limited, but is preferably 2 to 5 because it is necessary to provide a suction mechanism for each layer. If n exceeds 5, it becomes difficult to secure a sufficient suction range on the rotating drum, and the structure of the fixed drum and the rotating drum becomes very complicated, so that the reduction in equipment cost, which is the original purpose, is impaired. End up. Furthermore, in order to give each layer a sufficient function as an absorbent article, it is more preferable that n is 2 to 3.
The outer diameter of the rotating drum 3 is preferably 2 m or less in consideration of the manufacturable limit and workability such as assembly. Assuming that the product length of a general absorbent article is 100 to 500 mm, the number of surface patterns is 2 to 20 due to the relationship with the outer diameter of the rotating drum 3.
Further, in the fiber stacking method of the present invention, without using a rotating drum, an appropriate number of multilayer integrated members are arranged on the conveyor belt, a plurality of shooters provided with suction mechanisms are arranged in parallel, and the conveyor belt is moved. It is also possible to pile up the fibers sequentially.
