By the above configuration, the operation of the turret type cup sleeve manufacturing apparatus according to the embodiments of the present invention is as follows.

When the cardboard cup sleeve member S1 is supplied from the sleeve member supply unit (not shown) to the first turret 1, the sleeve is formed around the male support 11 of the first turret 1. The cardboard cup sleeve member S1 is wound around the outer circumferential surface of the mail type support 11 of the first turret 1 by a unit (not shown), and the overlapping portions of the cup cup sleeve member S1 are ultrasonic welding machines (not shown). Is bonded to the cylindrical cup sleeve member S2.

The cylindrical cup sleeve member S2 wound on the male support 11 of the first turret 1 is transferred toward the second turret 2 while the first turret 1 is rotated, and then the first turret ( Transfer from the mail type support 11 to the female type support 21 of the second turret 2 by the pressure of air discharged from the air discharge passage 11a formed in the mail type support 11 of 1). do. At this time, since the air discharge passage 11a of the mail type support 11 discharges compressed air while forming an acute angle with the outer circumferential surface of the mail type support 11, the force is efficiently transmitted to the cylindrical cup sleeve member S2. The female type support 21 allows the cylindrical cup sleeve member S2 to be stably seated on the inner surface by using the vacuum suction force generated from the first air passage 21a formed therein.

The cylindrical cup sleeve member S2 seated on the female support member 21 of the second turret 2 has the lower curling molding molds 31 and 32 and the upper curling molding mold as the second turret 2 rotates. 41 and 42 are transported to the place where the lower and upper curling molds 31 and 32 and the upper and lower curling molds 41 and 42 are engraved twice.

In this way, the lower and upper portions of the cylindrical cup sleeve member S2 are engraved by the lower curling molding molds 31 and 32 and the upper curling molding molds 41 and 42, and the female support 21 is cylindrical. Since the bearing force is relatively weak because it supports the outer circumferential surface of the cup sleeve member S2, air is injected from the first air nozzle 41b or the second air nozzle 41c of the upper curling molding molds 41 and 42, thereby avoiding it. It serves to reinforce the support of the mail type support (21). In addition, the air is injected from the first air passage 21a or the second air passage 21b of the female type support 21, or the vacuum suction input is generated to further reinforce the supporting force of the female type support 21. It will play a role.

The air injected from the first air nozzle 41b or the second air nozzle 41c of the upper curling molding 41 and 42 may use air heated at 120 to 160 ° C., and the cylindrical cup sleeve member S2 may be used. On one side or both sides, biodegradable resins such as starch, cellulose, chitin, chitosan, polycaprolactone (PCL), polylactic acid (PLA), poly3-hydroxylactic acid (PHB), etc. are applied in a thickness of 0.02 ~ 0.07mm. The resin foaming process is performed by hot air heated at 120 to 130 ° C.

The starch is a natural polymer and is widely used as a biodegradable trash bag by blending with starch such as corn, potato and sweet potato in Europe and the United States, using gelatinized starch and aliphatic polyester. Starch is gelatinized by heating if water is present. Like plastics, blends of polycaprolactone and gelatinized starch that can be plasticized but have no water resistance and are excellent in hydrolysis resistance have been developed. The production of blends of polycaprolactone and gelatinized starch requires structural control technology together with gelatinization technology of starch under high-technical power such as extractor, and polycarprolactone is maintained by maintaining the viscosity of gelatinized starch larger than the melt viscosity of PCL. It is possible to prepare a blend of a continuous phase. In addition, the addition of plasticizers and compatibilizers for the prevention of deterioration of physical properties and the improvement of physical properties due to the recrystallization of starch has been considered, and granular starches such as corn are uniformly dispersed in aliphatic polyester using a high-speed flow mixer. Blended water is being developed, which has the advantage of high biodegradation rate, high elastic modulus and high water resistance.

The polycaprolactone (PCL) is a synthetic polymer, and among the aliphatic polyesters synthesized from petrochemical raw materials, it is highly biodegradable and positioned as a standard for biodegradable plastics because microorganisms are widely distributed in various environments under aerobic and basic conditions. Occupies. Polycaprolactone (PCL) has been industrially produced for a long time, and recently, blends with starch or cellulose materials are widely used as copolymerization components with lactic acid, and have a low melting point but high temperature and high humidity compared to other aliphatic polyesters. It is stable and a large amount is produced as a high molecular weight aliphatic polyester obtained by ring-opening polymerization of (epsilon) -caprolactone.

The polylactic acid (PLA) is a synthetic polymer, and the polylactic acid (PLA) chemically synthesized by using L-lactic acid, which has been fermented by microorganisms from renewable resources such as starch, as a monomer, is more effective than the conventional synthetic polylactic acid (PLA) Due to its low cost, a large amount is used, and the second-processed polylactic acid (PLA) in film or fiber has excellent hydrolysis resistance. Polylactic acid (PLA) is hydrolyzed by water, low molecular weight, and then degraded by microorganisms. In general, polylactic acid (PLA) is known to have low moisture or gas barrier properties. It is expected to use in many ways.

The above-mentioned poly3-hydroxylactic acid (PHB) has high productivity among polyhydroxyalkanoate (PHA) and is expected to be a thermoplastic material derived from living organisms, but its crystallinity is so high that mechanical properties are poor and easy to thermally decompose. There are drawbacks such as poor processing. Thus, blends composed of poly3-hydroxylactic acid (PHB) and polycaprolactone (PCL) have been developed, which has better processing properties than poly3-hydroxylactic acid (PHB) alone and makes PHBV copolymers with microorganisms. Compared with the above, the biodegradable plastic of a certain composition is obtained and the cost is low. Poly3-hydroxylactic acid (PHB) is rapidly decomposed by the microorganisms despite the high melting point, but when processed into a film through heat treatment, the degradation rate by the microorganisms is significantly reduced.

The cup sleeve S3 of which the molding is completed by the lower curling molding molds 31 and 32 and the upper curling molding molds 41 and 42 is engraved by the lower and upper curling molds 21 of the second turret 2. Is discharged to outside.
