Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for continuously supplying a belt-shaped member without interruption, and more particularly to a device for disposing a body fluid absorbing pad which can be arranged in, for example, pants to absorb urine. The present invention relates to an apparatus and a method for continuously supplying a belt-like member capable of continuously supplying a belt-like member.

[0002]

2. Description of the Related Art A bodily fluid absorbing pad of this type, called a urine absorbing pad, for absorbing urine is usually provided with an absorbent material 1001 disposed on a waterproof sheet (base sheet) 1000 as shown in FIG. , And the center surface material 1002
And the side surface material 1003. By the way, this type of center surface material 1002 and side surface material 1003 are made of a soft material, and the center surface material 1002 allows urine to pass through, while the side surface material 1003 does not allow urine to pass. The center surface material 1002 and the side surface material 1003 are used by cutting and joining long strip-shaped members so as to partially overlap each other.
Therefore, the center surface material 1002 and the side surface material 1
003 are wound on different bobbins, respectively, and the center surface material 1002 and the side surface materials 1
003 are sequentially supplied.

[0003]

Such a long center surface material or side surface material is wound on a bobbin as described above. For example, the center surface material is supplied to the waterproof sheet 1000 side. In this case, since the waterproof sheet is also continuously supplied, the center surface material 1002 needs to be continuously supplied without a break. When the center surface material wound on a certain bobbin is sequentially supplied and the remaining amount becomes small, the center surface material 10 is left as it is.
Since the supply of 02 is temporarily stopped, it is necessary to continuously supply another center surface material 1002 from another bobbin. However, when sequentially supplying the center surface material from different bobbins in this way, the supply of the center surface material from the bobbin is stopped once, so that the supply of the center surface material of the next bobbin can be more appropriately supplied. It is necessary to operate the manufacturing apparatus again and continue the supply operation of the center surface material after performing the appropriate work. For this reason, there is a problem that the supply operation of such a band-shaped center surface material is interrupted, and the production line of the bodily fluid absorbing pad is temporarily stopped. In this regard, the supply of the side surface material is the same as the supply of the center surface material. Therefore, an object of the present invention is to solve the above-described problems and to provide a continuous supply device of a belt-like member and a continuous supply method of the belt-like member which can continuously supply the belt-like member without stopping the apparatus. .

[0004]

In the present invention, the first object is to supply one of the band-shaped members to a portion to be supplied.
A rotating body, a second rotating body having the other band-shaped member, and a first rotating body.
When one belt-shaped member of the rotator or the other belt-shaped member of the second rotator is transported to the supply target site side, and the one belt-shaped member of the first rotator is supplied and approaches the end. The end of one strip is attached to the beginning of the other strip of the second rotator to connect one strip to the other strip, and the other strip of the second rotator is supplied. A belt-like member connecting means for connecting the other belt-like member to the one belt-like member by attaching the terminal end of the other belt-like member to the start end of one belt-like member of the first rotating body when approaching the terminal end. This is achieved by a continuous feeding device for a belt-shaped member, which is provided with the device.

The belt-shaped member connecting means has the following functions. When one of the band members of the first rotating body is supplied and approaches the end, the terminal end of one of the band members is attached to the starting end of the other band member of the second rotating body, so that one of the band members and the other of the other members are attached. The belt-shaped members are connected. Further, conversely, when the other band-shaped member of the second rotating body is supplied and approaches the end, the end of the other band-shaped member is attached to the starting end of one band-shaped member of the first rotating body, and the other band-shaped member is connected to the other band-shaped member. One of the band members is connected. In this way, the one band-shaped member and the other band-shaped member can be continuously and continuously supplied to the supply target portion. Thus, one of the band-shaped members or the other band-shaped member can be supplied to the supply target portion without stopping the manufacturing apparatus, so that the manufacturing efficiency can be improved.

[0006] In the present invention, preferably, the belt-like member connecting means presses the terminal end of one of the belt-like members against the attached body at the start end of the other belt-like member, and the terminal end of the other belt-like member. Is pressed against the attached body at the start end of one of the band-shaped members. According to the present invention, in this manner, one of the band-shaped members and the other band-shaped member can be continuously and continuously supplied with a relatively simple structure.

[0007] In the present invention, the above-mentioned object is preferably such that the band-like member connecting means connects the end portion of one of the band-like members to the second.

When adhering to the start end of one of the band members of the rotating body, the feeding speed of the other band member by the conveying means is reduced. In the present invention, preferably, the band-shaped member connecting means lowers the feed speed of one band-shaped member, or lowers the feed speed of the other band-shaped member, thereby more reliably connecting the one band-shaped member and the other band-shaped member. It can be carried out.

According to the present invention, when one of the belt-like members and the other of the belt-like members are alternately and continuously supplied to a supply target portion, one of the belt-like members of the first rotating body is supplied. When approaching the end, the end of one band-shaped member is attached to the start end of the other band-shaped member of the second rotating body to connect one band-shaped member and the other band-shaped member, and conversely, the second rotating body When the other band-shaped member is supplied and approaches the end, the end of the other band-shaped member is attached to the start end of one band-shaped member of the first rotating body, and the other band-shaped member is connected to one band-shaped member. This is achieved by a method for continuously supplying a belt-shaped member.

According to the present invention, when one of the belt-like members and the other belt-like member are alternately and continuously supplied to the supply target portion, when one of the belt-like members of the first rotating body is supplied and approaches the end, The end of one strip is attached to the start of the other strip of the second rotator to connect the one strip to the other strip. Conversely, when the other band-shaped member of the second rotating body is supplied and approaches the end, the end of the other band-shaped member is attached to the starting end of one band-shaped member of the first rotating body, and the other band-shaped member is attached. And one of the belt-shaped members. Thereby, one of the band members and the other band member are
It can be continuously and continuously supplied to the supply target portion. Thus, one of the band-shaped members or the other band-shaped member can be supplied to the supply target portion without stopping the manufacturing apparatus, so that the manufacturing efficiency can be improved.

Therefore, the first belt-like member supply means 33 shown in FIG.
Is described with reference to FIGS. 31 to 35, and the structure of the continuous supply devices 25, 33, 35, and 210 provided in total at four locations will be described as a representative, but the structure of each continuous supply device is almost the same. . FIG. 31 shows a first belt-shaped member supply means 33 as a continuous belt-shaped member supply device shown in FIG. Side surface material 3 sent out from bobbin 33a by the force of uncoiler 33f and by the flow force of the entire line
4 (material 34c) and the side surface material 34 (material 34c) sent out from the bobbin 33b are rollers 33j, 33j
Thereby, the belt-shaped member is guided to the connection means 33g side. By rotating the roller 33h in the r1 direction, the side surface material 34 on the bobbin 33a or the side surface material 34 on the bobbin 33b side can be guided. The connecting means 33g of the belt-shaped member has a cylinder 33m, which is shown in FIG.
As shown in (B) and FIG. 33, the rod 33n is connected to the plate 33p. The plate 33p has a pressing roller 33r. The cylinder 33m is
A hydraulic cylinder, for example, a pneumatic cylinder or a hydraulic cylinder can be used. The rod 33n is
When the rod 33n extends from the state shown in FIG. 32A to the state shown in FIG. 32B, the rod 33n moves toward the roller 33h and pushes the roller 33r.

In the example shown in FIG. 32A, an adhering material (adhesive material) is attached to the starting end 34s of the side surface material 34 on the bobbin 33a side.
501 is set. Attachment surface 5 of this attachment material 501
01a faces the side surface material 34 on the bobbin 33b side. Therefore, as shown in FIG.
When 3n is extended, the adhesion material 501 and the side surface material 34 on the bobbin 33b side are pressed between the rollers 33r and 33h. As a result, the starting end 34s of the side surface material 34 on the bobbin 33a side adheres to the almost end portion 34e of the side surface material 34 on the bobbin 33b side via the adhering material 501, so that the side surface material 34 of the bobbin 33a is , Can be connected without interruption to the side surface material 34 on the bobbin 33b side. The cylinder 33m operates according to a command from the control unit 500 as shown in FIG.

Next, FIGS. 34 and 35 and FIGS. 36 and 37
, The two bobbins 33a and 33b in FIG.
The continuous connection supply operation of the side surface members 34, 34 will be described. First, in step S100 in FIG. 36, the bobbin 33b in FIG. 31 continuously supplies the side surface material (material 34c). In the case where the side surface material 34 of the bobbin 33b becomes small in step S101 in FIG. 36 and the terminal end 34e is close as shown in FIG. 34A, the bobbin 33b is replaced with the bobbin 33a in step S102 in FIG. In preparation for the above, the speed of the side surface material 34 shown in FIG. 31 is reduced by reducing the overall speed of the manufacturing apparatus.

In step S103 of FIG. 36, the cylinder 33m is operated as shown in FIG. 34 (B), and the adhering material of the starting end 34s of the side surface material of the bobbin 33a with respect to the side surface material 34 of the bobbin 33b. 501 is brought into close contact. Thereby, in step S104, bobbin 3
3b, the end portion 34e of the side surface material 34, and the bobbin 33
The starting end 33 s of the side surface material 34 a is instantly and firmly connected. Thereafter, the speed of the motor (not shown) is increased by a command from the control unit 500, so that the bobbin 33
a side surface material 34 is fed at a predetermined speed. At this time, in step S104, the side surface materials 34 of the bobbin 33a and the bobbin 33b are adhered by the adhesion material 501, and therefore, the bobbin 33a and the bobbin 33b are formed using a certain range of the side surface material 34 including the connection portion. Urine collection pad 1
7 is discharged from the discharge unit 330 of FIG. Thus, it is possible to reliably remove the urine absorbing pad 17 of the product that may include the adhesion material 501 from the discharge unit 330. Since the side surface material 34 of the bobbin 33b in FIG. 31 has already been used up, a new bobbin 33b
As shown in FIG. 35A, an adhering material 501 is similarly attached to the starting end 34s of the side surface material 34 of the new bobbin 33b.

Next, the flow shifts to step S106 in FIG.
In FIG. 35 (A), the supply of the side surface material on the bobbin 33a side is continuously performed. If the side surface material on the bobbin 33a side is running low in step S107, the process proceeds to step S108, where the bobbin 33a In preparation for replacing the bobbin 33b, the speed of the side surface material is reduced by reducing the overall speed of the manufacturing apparatus. Then, in step S109, the cylinder 33m is operated as shown in FIG. 35 (B), and the starting end 34s of the side surface material of the bobbin 33b with respect to the side surface material of the bobbin 33a.
Is adhered instantaneously and firmly. Thereby, the start end 34 of the side surface material 34 of the bobbin 33b is compared with the end 34e of the side surface material of the bobbin 33a.
s can be reliably connected. After this, the control unit 5
By increasing the speed of a motor (not shown) according to the instruction of 00, the surface material 34 of the bobbin 33b is fed again at a predetermined speed.

In step S110 of FIG.
The urine absorbing pad 17 made by using the side surface material 34 in a certain area including the connection portion between the end portion 3a and the start end 34s of the bobbin 33b is discharged from the discharge portion 330 in FIG. Since the side surface material 34 of the bobbin 33a in FIG. 31 has been used up, a new bobbin 33a is mounted, and as shown in FIG. 34 (A), the start end 34s of the side surface material 34 of the bobbin 33a is provided. Attaches the adhering material 501 in advance.

In this way, when the side surface material of one bobbin is running out, the surface material of the other bobbin is brought into close contact with the adhering material 501 so that it can be continuously fed. At this time, by reducing the speed of the side surface material, this operation can be performed easily and reliably. After this connection operation is completed, the feed speed of the side surface material may be increased to the speed at which the original side surface material is fed. The connecting operation of such a band-like member is performed by a second band-like member supply unit 35 for supplying the center surface material 36 shown in FIGS. 1 and 3, a second tissue supply unit 25 for supplying the second tissue 26, and FIG. 4 can be similarly performed in the back sheet 15 supply device. In addition, the force of the whole line of each belt-shaped member can be sent by the force of one motor. In addition, the uncoiler 33f, 3
5f, 25f, and 14f are inclined toward the bobbin as the amount of the corresponding bobbin band member decreases, so that the bobbin band member can be stably fed regardless of the amount of the band member. The uncoiler can be configured to have, for example, a motor, a pulley, and a belt that rotates around the pulley. The present invention is not limited to the above embodiment.
In the embodiment of the present invention, in FIG. 17, the wrinkle removing means 80 uses a roller having a relatively small diameter and the same diameter. However, the invention is not limited to this. For example, a roller 80f as shown in FIGS. 27 and 28 may be used. It can also be used. The roller 80f has the largest diameter at the center and gradually becomes smaller in a tapered shape toward the end. Even if a roller having such a shape is used, the wrinkles 81 of the wide center surface member 36 can be easily removed.

In still another embodiment shown in FIGS. 29 and 30, instead of using a roller, a fixed plate 80k can be used as the wrinkle removing means 80. The fixed plate 80k has a surface 80m with which the wide center surface member 36 contacts, for example, formed in a semicircular shape. Even in this case, the wrinkles 81 of the center surface member 36 can be reliably removed.

The urine absorbing pad shown in FIGS. 5 to 8 in the above embodiment is used as a body fluid absorbing pad.
The shape and the material of each layer or the laminated structure can of course adopt other types or methods, and can be arbitrarily selected according to the application.

In the above-described apparatus for continuously supplying a belt-shaped member according to the present invention, a direct-acting fluid pressure cylinder is used to connect one belt-shaped member to the other belt-shaped member. Of course, it is also possible to employ a rotating body such as described above or another type. The continuous supply device of the band-shaped member of the present invention can be applied to a case where it is necessary to continuously supply the band-shaped member in other types or other fields other than the production device for producing the body fluid absorbing pad. It is.
