<<<The Fen Pei > of 1 class and 2 class material feeding apparatus 10 and 50;>>
In the present embodiment, as described above, 1 class material feeding apparatus 10 shown in Fig. 4 A be used to supply back tablet
The material 3 of 3s, and 2 class material feeding apparatus 50 shown in fig. 6 be used to supply the material 4 of leakproof tablet 4s.This is because
The number of replacement per unit time in two feeding rotary shafts 64 and 64 for the coil of material 3C of back tablet 3s is (secondary/small
When) compare two replacement numbers per unit time for feeding the coil of material 4C in rotary shafts 24 and 24 for leakproof tablet 4s
(secondary/hour) is big.
Specifically, in 2 class material engagement devices 60, the material 4f that needs a person with the qualifications of a general is drawn to compression element as shown in Figure 7 A
67K, therefore, the preparation for bonding are more complicated than 1 class material engagement device 20.2 class material engagement devices 60 are divided as a result,
Dispensing have it is smaller replace number, coil of material 4C for leakproof tablet 4s per unit time, to inhibit worker
The increase of burden.
It should be noted that in this example, the replacement number per unit time of the coil of material 4C for leakproof tablet 4s
(secondary/hour) is smaller than the number of replacement per unit time (secondary/hour) of the coil of material 3C for back tablet 3s, wants below
Point mainly helps this.
First, in this example, the feeding length LGH4 ratios of the material 4 for leakproof tablet 4s are used for back tablet
The feeding length LGH3 of the material 3 of 3s is short, and the material 4 for leakproof tablet 4s is by the 2 class materials for generating single diaper 1s
Expect that engagement device 20 is fed, the material 3 for back tablet 3s is by the 1 class material engagement device for generating single diaper 1s
60 feedings.
That is, as shown in Figure 2 A, in this example, the longitudinal direction of diaper 1s is on the direction of feeding material 3 and 4.With
Length on the longitudinal direction of diaper 1s is compared, length LGH3s of the length LGH4 than back tablet 3s of leakproof tablet 4s
It is small.
Accordingly, for per unit time from the consumption length LGH3 of the coil of material 3C and 4C material 3 and 4 consumed and
LGH4 is used for consumption length of the consumption length LGH4 than the material 3 for back tablet 3s of the material 4 of leakproof tablet 4s
LGH3 is small.This contributes to, and the number of replacement per unit time (secondary/hour) of the coil of material 4C for leakproof tablet 4s is more
It is small.
It should be noted that for example, by by the ratio (V3 of feed speed V3 and feed speed V4:V4 aforementioned feeding length) is maintained
Ratio (the LGH3 of degree:LGH4), realize as described above so that being used for the feeding length LGH4 ratios of the material 4 of leakproof tablet 4s
The feeding length LGH3 of material 3 for back tablet 3s is short.Here, feed speed V3 is filled for being supplied to 1 class material
Set the speed (mpm) of the material 3 needed for 10 supply processing units 110, feed speed V4 is for 2 class material feeding apparatus 50
Supply the speed (mpm) of the material 4 needed for processing unit 110.
Second, in this example, since leakproof tablet 4s is made of film, and back tablet 3s is by adhesive-bonded fabric system
At so when will be for the thickness (average thickness) of the material 4 of leakproof tablet 4s and use in the form of coil of material (3C, 4C)
When the thickness (average thickness) of the material 3 of back tablet 3s is compared, the material 4 for leakproof tablet 4s compares on thickness
Material 3 for back tablet 3s is small, as shown in Figure 2 B.In general, from the viewpoint of loading and conveying by truck, material
The outer diameter of coil 3C and 4C have the upper limit.In this case, if the thickness of material is smaller, with the material of same outer diameter winding
Length it is bigger.As a result, as described above for leakproof tablet 4s material 4 relatively small thickness contribute to it is aforementioned per unit time
Replace the reduction of number (secondary/hour).
However, it is not limited to this to replace the different requirement of number between material 3 and 4 per unit time.That is, when per unit
Between replace number (secondary/hour) can due to other are required difference.

The number of replacement per unit time (secondary/hour) of circle increases.It is thus preferable that 1 class material feeding apparatus 10 is used for paper pulp gas
Flow the coil of material of networking adhesive-bonded fabric.In this case, in general, being made of paper pulp airlaid nonwoven fabrics and being material
The thickness (average thickness) of the material of coil form than be respectively coil of material 2C and 3C form for top tablet 2s and
The thickness (average thickness) of the material 2 and 3 of back tablet 3s is big.Accordingly, for the coil of material for top tablet 2s
2C and coil of material 3C for back tablet 3s replaces number (secondary/hour) nothing more airlaid than paper pulp per unit time
The coil of material of textile fabric it is small.In this case, 2 class material feeding apparatus 50 can be used for top tablet 2s and back
The coil of material 2C and 3C of tablet 3s.
