Further, the belt-like materials may be unwound and delivered from the rolls 4a and 4b by rotating the hangers 3a and 3b.

  • the intermittently-treating unit T is comprised of a cutting unit which cuts the belt-like material into belt-like material segments Sp of a constant length. That is, the intermittently-treating unit T comprises a cutter roll 21 having a cutting blade 20, and an anvil roll 22 arranged facing the cutter roll 21.
  • the belt-like material S is subjected to the cutting operation once whenever the cutter roll 21 and the anvil roll 22 rotate by 360 degree. In other words, the cutting operation is conducted once whenever the belt-like material S is conveyed by the length of the belt-like material segment Sp.
  • the rotations of the cutter roll 21 and the anvil roll 22 are in synchronism with the rate of production or the conveying speed of the apparatus for producing absorptive articles.
  • the belt-like material S is intermittently treated at a treating timing determined depending upon the rate of production or the conveying speed of the apparatus for producing absorptive articles.
  • the belt-like material segment Sp is temporarily held on the anvil roll 22, and is sent to a next step.
  • One absorptive article is produced from one belt-like material segment Sp.
  • the belt-like material may be subjected to compression treatment. Therefore, the treatment in the intermittently-treating unit T includes at least one of cutting of the belt-like material and compression of the belt-like material. Alternatively, the belt-like material may be subjected to any further intermittent treatment, such as embossing, shaping including folding, application of an adhesive or assembling with another member.
  • Fig. 1 illustrates a condition where the belt-like material-feeding apparatus 1 is in a steady operation.
  • the belt-like material is delivered from the roll 4a at the feed position 7sp.
  • the belt-like material then passes through the splicing unit 10, and is delivered to the intermittently-treating unit T at a nearly constant speed due to the intermediate roll 8 and the delivery belt 19.
  • the delivery belt 9 is not driven to rotate and, therefore, no belt-like material is delivered from the roll 4b at the standby position 7st.
  • the splicing operation is retarded, i.e., the splicing operation is not conducted at this moment.
  • the timing now becomes suited for the splicing operation then the splicing operation is conducted.
  • the splicing operation is conducted as described below. Specifically, as shown in Fig. 3 , the cutting unit 14 is actuated, and the belt-like material Ssp is thus cut. At the same time, the splicing roll 12 is actuated, and the belt-like material Ssp is thus pushed onto the pressure-sensitive adhesion member A. As a result, as shown in Fig. 4 , a leading end part of the belt-like material Sst is spliced to a tail end part of the belt-like material Ssp, and a splicing region SPL including the pressure-sensitive adhesion member A is formed between the belt-like material Ssp and the belt-like material Sst. During the splicing operation, the delivery of the belt-like material Sst is continued due to the rotation of the splicing roll 12.
  • the leading end part of the belt-like material Sst has been arranged on the holding unit 13, in advance, by, for example, an operator.
  • the pressure-sensitive adhesion member A has been partly attached to the leading end part of the belt-like material Sst and the remaining pressure-sensitive adhesion member A is held on the holding unit 13 with the adhesive surface facing upward.
  • the belt-like material Ssp is pushed onto the adhesive surface.
  • the delivery belt 9 and the delivery roll 13 are actuated simultaneously with the start of the splicing operation and, as shown in Fig. 5 , the belt-like material Sst is delivered to the intermittently-treating unit T from the roll 4b at the standby position. As a result, the belt-like material is continuously fed to the intermittently-treating unit T. In this case, the delivery belt 9 and the delivery roll 13 have been actuated and, thus the rotation of the roll 4b can be easily started.
  • the belt-like material Ssp may be at least partly cut by the cutting unit 14 and may, thereafter, be completely cut by being delivered by the delivery belt 9 and the delivery roll 13.
  • the carrier 5 is rotated clockwise as shown in Fig. 6 , to move the roll 4b to the supply position 7sp.
  • the rotation of the delivery belt 9 is stopped.
  • the roll 4a is removed from the hanger 3a that has moved to the standby position 7st, and a new roll is mounted on the hanger 3a.
  • the splicing operation is conducted again.
  • the timing is suited for the splicing operation is judged as described below. That is, when the splicing operation is conducted, the splicing region SPL is formed as described with reference to Fig. 4 , and the splicing region SPL then arrives at the intermittently-treating unit T. At this time, if the intermittently-treating unit T is at its treating timing, i.e., if the splicing region SPL is subjected to the cutting treatment, then the pressure-sensitive adhesion agent contained in the splicing region SPL may adhere to the cutting blade 20, as described in the beginning, which is undesirable.
  • a timing at which the splicing region SPL that has arrived at the intermittently-treating unit T is not treated thereby is considered to be a timing suited for the splicing operation.
  • the splicing operation is conducted at a timing suited for the splicing operation, the thus formed splicing region SPL is not then treated at the intermittently-treating unit T. If the splicing operation is conducted at timings other than the timing suited for the splicing operation, the thus formed splicing region SPL is then treated at the intermittently-treating unit T.
  • the timing is suited for the splicing operation can be judged based upon the treating timing of the intermittently-treating unit T and the time required for the splicing region SPL to arrive at the intermittently-treating unit T from the splicing unit 10.
  • the required time can be obtained from the length of the conveying passage from the splicing unit 10 to the intermittently-treating unit T and the conveying speed.
  • the splicing timing of the splicing unit 10 is controlled based on the treating timing of the intermittently-treating unit T. It is, further, judged if the splicing region SPL is going to be treated in the intermittently-treating unit T. If it is judged that the splicing region SPL is going to be treated in the intermittently-treating unit T, the splicing operation is retarded, and the splicing operation is executed if it is judged that the splicing region SPL is not going to be treated.
  • the cutting operation is conducted by the intermittently-treating unit T whenever the belt-like material S is conveyed by the length of the belt-like material segment Sp
  • the splicing operation is retarded by a period required for the belt-like material S to be conveyed by the length of the belt-like material segment Sp. It is, therefore, desired that the conveying distance from the marker sensor 24 to the splicing unit 10 is set to be longer than the length of the belt-like material segment Sp.
  • Fig. 7 illustrates a routine for a belt-like material feed control according to an embodiment of the present invention.
  • step 100 it is judged if the marker M is detected by the marker sensor 24, i.e., when the remaining amount of the belt-like material of the roll 4a, 4b at the feed position became smaller than the lower-limit amount. If the marker M has not been detected, the processing cycle is ended. When the marker M is detected, on the other hand, the routine proceeds to step 101 where it is judged if the timing is now suited for the splicing operation. Step 101 is repeated until the timing becomes suited for the splicing operation. When the timing is now suited for the splicing operation, the routine proceeds to step 102 where the splicing operation is conducted.
  • step 103 the delivery belt 9 and the delivery roll 13 are actuated, and the belt-like material Sst is delivered from the roll 4b, 4a at the standby position 7st.
  • step 104 it is judged if the belt-like material Sst is delivered by the predetermined amount. Step 104 is repeated until the belt-like material Sst is delivered by the predetermined amount.
  • the routine proceeds to step 105 where the carrier 5 is rotated by 180 degrees.
  • the hangers 3a and 3b may be provided with revolution sensors to calculate the remaining amount of the belt-like material of the roll 4a, 4b based on the number of revolutions of the rolls 4a, 4b detected by the revolution sensors.
  • the remaining amount of the belt-like material of the roll 4a, 4b is smaller than the lower-limit amount, may be judged based upon the outer diameter of the roll 4a, 4b detected using a photoelectric tube sensor, proximity sensor, limit switch or camera.
  • the lower-limit amount may be a constant value or may be set based on the rate of production of the apparatus for producing absorptive articles. This makes it possible to lower the effect of variation in the thickness of the belt-like material of the roll 4a, 4b.
  • an accumulation unit may be arranged between the splicing unit 10 and the intermittently-treating unit T to temporarily accumulate the belt-like material.
  • the splicing operation may be conducted using an adhesive agent A.
  • the splicing region SPL containing the adhesive agent A is formed.
  • the splicing operation may be conducted using the heat-welding.
  • the splicing region SPL that is formed becomes harder than the other regions of the belt-like material. Therefore, if the cutting operation is conducted to the splicing region SPL, then the belt-like material may not be reliably cut or the cutting blade 20 may be damaged.
  • the present invention is free from this problem.
  • the tail end part of the belt-like material Ssp from the roll 4a, 4b at the feed position 7sp includes an excess portion Ex extending rearward beyond the adhesive agent A.
  • the excess portion Ex is included in the splicing region SPL. This is because if the excess portion Ex is subjected to the cutting operation, pieces of the belt-like material that are formed may scatter to contaminate the steps. In other words, according to the embodiment of the invention, the excess portion Ex is also prevented from being subjected to the cutting treatment.
  • the splicing timing of the splicing unit 10 is controlled so that the splicing region SPL is not subjected to the treatment of the intermittently-treating unit T.
  • the splicing timing of the splicing unit 10 may be controlled so that the splicing region SPL is subjected to the treatment of the intermittently-treating unit T.
