摘要:
The present invention provides a bladder-type jig suitably used for manufacturing a stiffened panel structure using a hat stringer. The present invention has an advantage that deformation of prepreg can be suppressed effectively, and durability of the jig can be improved so that repeated use of the jig is achieved. To be specific, a body (11) of the bladder includes a pipe-shaped portion (14) and a coating film (15) covering the outer peripheral surface of the pipe-shaped portion (14). The pipe-shaped portion (14) is a main body portion of the body (11), and is made of a silicone rubber composition material such that its transverse cross-section has a trapezoidal pipe shape. Both side edge portions of an exposed wall portion (11b) corresponding to a lower base of the transverse cross-section are thickened edge portions (11d) which are greater in thickness than another wall portions. The thickened edge portions (11d) support the exposed wall portion (11b) from inward of the body (11), and can suppress the exposed wall portion (11b) from getting deformed inwardly.

A thread material cutting device 90 is provided which is used in an extraction bag sheet manufacturing apparatus, the thread material cutting device having a compact apparatus configuration without the use of a cutter. An extraction bag manufacturing apparatus with the thread material cutting device 90 incorporated therein includes welding means (first sealing device 61) in which tags 2 retained on a carrying face of a carrier 10 at prescribed intervals and a thread material 3 arranged so as to be placed over the tags 2 are press-heated and thereby welded on the carrier 10. The thread material cutting device 90 has tension application means such as a pressing plate 91 configured to engage with the thread material 3 placed between adjacent tags 2 so as to apply tension to the thread material 3. While the welding means is press-heating the thread material onto the tags, the tension application means applies tension to the thread material 3 so as to cut the thread material 3.

A method of manufacturing an extraction bag sheet 5 includes: (1) a step of placing and holding tags 2 on a rotary supporting body 10 at predetermined intervals; (2) a threading step of threading a string 3 into a continuous pattern on the circumferential surface of the rotary supporting body 10; (3) a bonding step of bonding the string 3 to the tags 2; (4) a step of supplying a water-permeable filter sheet 4 onto the tags and the string 3 placed on the rotary supporting body 10; (5) a bonding step of bonding the water-permeable filter sheet to the string on the rotary supporting body; and (6) a bonding step of bonding the water-permeable filter sheet to the tags on the rotary supporting body. In the bonding steps of (3), (5), and (6), bonding heads are used which are moved reciprocally and oscillatingly about the center axis of the rotary supporting body 10 and moved vertically relative to the circumferential surface of the rotary supporting body 10 by an oscillation servo motor 66 and a vertical movement servo motor 65. With this configuration, the tags are disposed on the strip-like water-permeable filter sheet at predetermined intervals, and the long string is placed into a specific convolution pattern. The bonding conditions for the tags, string, and water-permeable filter sheet are thereby optimized when the extraction bag sheet is manufactured.

A packing-packaging machine 70 includes: sheet feeding means (feeding rollers 74) for running a tubular body formed from an extraction bag sheet 5; a horizontal bonding unit 76 for forming a bag body by forming horizontal bonding on the tubular body at predetermined intervals; and an object dispensing unit 100 for dispensing an object 85 to be packaged to the bag body during a repetition of the formation of the horizontal bonding. The object dispensing unit 100 includes a shutter (a measure shutter 103) for opening and closing a falling path of a predetermined amount of the object 85 into the bag body. The shutter is opened and closed such that the predetermined amount of the object 85 and another predetermined amount of the object 85 fall with a spacing therebetween, and that before the horizontal bonding is formed on the bag body packed with the predetermined amount of the object which has been dropped during opening-closing operation of the shutter, the other predetermined amount of the object for a next bag body starts falling. With the packing-packaging machine 70, the rate of packing-packaging is drastically improved.

An engagement chain (12) includes a pair of first and second chain members (12A, 12B) that are engaged so as to be integrated with each other by moving in an advancing direction (Z1) and disengaged from each other so as to bifurcate by moving in a retreating direction (Z2) from the integrated engaged state. A first link plate (22) of the first chain member (12A) includes first and second pin holes (21A, 21B) through which a coupling pin (23) is inserted. A second link plate (29) of the second chain member (12B) includes first and second pin holes (28A, 28B) through which a coupling pin (30) is inserted. A first distance (D1) between the first and second pin holes (21A, 21B) of the first link plate (22) is shorter than a second distance (D2) between the first and second pin holes (28A, 28B) of the second link plate (29).

A method for manufacturing a package 10 in which an extraction bag 2 having four triangular surfaces is stored in an exterior bag 11 includes: a direction regulation step of regulating a direction of the extraction bag 2 to be a specified direction; a pressing step of pressing the extraction bag 2 so that one surface or one side of the extraction bag 2 is folded into two; a folding step of folding the extraction bag 2 by surface-pressing of the extraction bag 2 from both sides of surfaces that are overlapped upon being folded into two; and a packaging step of forming a package in which the folded extraction bag 2 is stored in the exterior bag. According to the method, when a trigonal-pyramid pack is packaged with an exterior bag 11, the trigonal-pyramid pack can be closed in the exterior bag in the state of being folded flat in a fixed form.
