    AIR COOLING SYSTEMS FOR PREFORM MOLDING
    [2] Index type injection molding machines with component cooling features at various stations are shown in US Pat. Nos. 5,728,409, 5,830,404, 5,750,162 and 5,817,345. Cooling of the preform on the index block using a component removal and cooling robot is a pending US patent application filed on October 7, 1998 by Ing et al. As a cooling device attached to the index mechanism. 09 / 167,699; 09 / 215,819, filed December 18, 1998 by Kutalowski, as cooling device having a name attached to an indexing mechanism; 09 / 261,880, filed March 3, 1999 by Domodossola et al., As Turret cooling blocks for indexing devices; The name of the invention is disclosed in 09 / 263,393, filed March 5, 1999 by Kozai et al., As a cooling device attached to an index mechanism, all of which is assigned to the assignee of the present patent application, Are united. However, these patents and patent applications do not teach the use of air amplifiers or the application of different cooling states at different index block stays.
    [3] After the preform has been removed from the mold, a preform whose surface is cooled by blowing air is shown in Japanese Patent Publication No. Hei 7-171888 to Sumitomo. U. S. Patent No. 5,232, 715 to Fukai also teaches the blowing of air over the outer surface of the preform while the preform is secured to the cooling oyster. In all these prior art examples, the preform is removed from the mold and cooled in the downstream part of the installation. In order for the preform to be removed from the mold without damage, sufficient cooling must be done. Therefore, the circulation time is violated for the downstream cooling.
    [4] U. S. Patent No. 4,449, 913 to Krishnakumar describes blowing air into the outer phase while the preform is still on the injection molded core mounted on the turret block. The air blowing nozzle is at a fixed distance from the preform. The Crisnakuma patent lacks the teaching of air amplifiers and does not explain how different cooling effects can be achieved in different regions of the preform surface.

    [9] The above object is achieved by the preform cooling apparatus and method of the present invention.
    [10] The present invention relates to an apparatus and a method for cooling a molded preform. Such apparatus and methods utilize air amplifiers to produce a flow of cooled air over the molded preform. In a first embodiment of the invention, an air amplifier is mounted to the component removal and cooling robot. In a second embodiment of the present invention, a plurality of air amplifier stations are positioned around the index block to cool the molded preform. In a third embodiment of the present invention, a vacuum system is provided such that the adhesion of the air flow generated by the air amplifier to the outer surface of the molded preform is improved. In a fourth embodiment of the present invention, an air amplifier is mounted to the movable plate and each amplifier has an internal bore sized to receive the molded preform to be cooled.
    [11] The method of the present invention comprises the steps of forming a plurality of molded preforms having a neck, a body and a gate area on a set of molded cores, moving the molded preforms to a position spaced apart from the molding station, Blowing cool air on the outer surface of the molded preform while the preform is positioned on the molded core. The blowing step includes generating a cooling air flow using at least one air amplifier.
    [12] The detailed description of the air cooling apparatus and method of the present invention, as well as other objects and advantages according to the air cooling apparatus and method of the present invention, are set forth in the description and the accompanying drawings in which like reference characters designate like elements.
    [22] Referring now to the drawings, FIG. 1 shows a tubular product or preform (such as a PET preform molded from 9921 W grade polyethylene terephthalate material with a weight of 28 grams with an average wall thickness in a body portion of 4.00 mm). An index type fixation of the injection molding machine 10 used to mold 12) is shown.
    [23] The molding machine 10 is equipped with 48 cavity high temperature runner molds 14 with four core sets 16 mounted on one side 18 of the four-sided index block 24. The mold 14 also includes a stationary mold half 20 having a molding cavity half 22 that engages one of the core sets 16 when the index block 24 is moved to the mold closed position. When the molding machine 10 is in a mold closing arrangement, the molten plastic material to be molded is passed through the mold cavity half 22 and fed into the mold. The mechanism for introducing the molten calcined material into the mold does not form the part of the present invention and thus is not described in detail herein. Any suitable means in the art can be used to inject the plastic material into the mold. Similarly, the mechanism for moving and rotating the index block 24 between the mold closed position and the mold open position also does not form part of the present invention. Thus, the movable and rotating mechanism is not described in detail. Any suitable moving and rotating mechanism can be used in the art.
    [24] After the mold 14 is opened after each injection cycle, the block 24 is rotated 90 degrees counterclockwise so that the molded preform 12 is retained on the forming core 16 until it is removed. If desired, each of the forming cores 16 may be cooled using any suitable cooling means in the art. After the batch of the second preform 12 is formed, the batch of the first molded preform faces the part removal and cooling robot 28. The period of each block rotation is approximately 15 while the preform 12 on the forming core 16 facing the component removal and cooling robot 28 is further cooled from ambient air or cooled air blown onto the outer surface. Seconds. After this additional cooling, the preform 12 is discharged into the cooled part removal tube 30 or 32 if necessary for further cooling. Any suitable means in the known art may be used to evacuate the cooled preform 12 from the forming core 16. Since the discharge mechanism does not form a part of the present invention, it will not be described in detail.
    [25] According to the invention, the component removal and cooling robot 28 comprises an air amplifier station 34 for cooling the preform 12 while the preform is in the forming core 16. The rotating head 26 moves to the air amplifier station 34 which aligns with the removal tube set 30, 32 or the preform set while the preform lies on each mold core 16. As shown in FIG. 1, the component removal and cooling robot 28 is mounted on a movable carriage 36 connected to an electric linear driver 40 by a continuous belt 38 to provide an air amplifier station 34 or component. The distance between one of the removal tubes 30 or 32 and the carriage 36 to which the corresponding preforms 12 are movable can thus move the robot 21 towards the index block 24 and can be spaced therefrom.
    [26] The air amplifier station 34 includes a mounting plate 42 mounted with a plurality of air amplifiers 44, such as an EXAIR super air amplifier. Each amplifier 44 is positioned and aligned to correspond to each opposing forming core 16 such that a preform 12 in which cooling fluid, ie ambient or cooled air, lies from the amplifier 44 to the forming core 16. ) In the preferred embodiment, the number of air amplifiers 44 is equal to the number of molded preforms 12.
    [27] 2 shows how the air amplifier 44 works in principle. As shown, the regulated air enters the compressed annulus 46 through the gap 48. The airflow supports the Coanda effect by following the profile 50 of the outlet nozzle. Fast flowing air creates a pressure drop at the inlet 52 through which ambient air is sucked, thereby increasing the overall air flow. The EXAIR amplifier will be equipped with shims (not shown) to produce the air jets described above. The thickness of the wedge affects the velocity of the jet as the velocity of the main flow air increases.
    [28] As shown in FIG. 1, within the batch the preform 12 is first cooled using an air amplifier 44. After cooling is complete, the robot 28 rotates so that the cooled preform 12 is discharged into the cooling tube 30 or 32 so that one of the sets of cooled tubes 30 or 32 is cooled down. ). The robot 28 moves to the index block 24. The robot is moved backwards away from the index block 24 and is rotated to bring the air amplifier station 34 to the position of the next cooling cycle.
    [29] After the preform 12 is further cooled in the cooling tube 30 or 32, the preform is discharged from the cooling tube 30 or 32. Any suitable means known in the art may be used to evacuate the cooled preform 12 from the cooling tubes 30, 32.
    [30] It is known that air amplifiers, such as EXAIR air amplifiers, are suitable in the field where relatively low supply of high pressure air is used to move large amounts of ambient air to the preform cooling through the amplifier nozzle. It is also known that the corresponding air flow rates and speeds through such amplifiers and the like can be adjusted to provide the desired level of cooling.
    [31] It is known that the cooling rate of the molded preform 12 is significantly enhanced when the air amplifier cools the preform. Table I shows the measured cooling data obtained using the cooling system of the present invention. The surface temperature of the preform 12 was measured in the three regions shown in FIG. Three regions include gate region 60, throat region 62, and preform body 64. Each air amplifier 44 is typically closest to the gate region 60 and farthest from the neck region 62. The various air pressures, flow rates (set using different thickness wedges) and the distance between the air amplifier and the preform are measured and shown in Table I.
    [32] Table I
    [33]
    [34] While the test is being preformed, the neck region 62 of the preform 12 remains surrounded and surrounded by the corresponding mold insert used to form the shape. As a result, the area of the preform is not exposed to air amplifier cooling. Nevertheless, the data relating to the neck area cooling rate show some unexpected results due to some cooling of the neck area due to air cooling of the adjacent main body 64 of the preform 12.
    [35] 4A is a graph showing the typical cooling rate (heat reduction) at the gate, neck body portion of the preform 12 on the core without using an air amplifier. In this graph the rise of the preform surface temperature of about 20 ° C. up to 10 seconds is shown. In addition, it shows that the remaining surface temperature for the main body 64 is about 90 ° C. after 45 seconds.
    [36] 4B is a graph showing the cooling rate that can be achieved using the cooling system of the present invention. This figure shows the improved cooling rate for the same preform on the core. As can be seen from this, the characteristic of the surface temperature rise was reduced to less than 5 DEG C for only 5 seconds, and after 45 seconds, the surface temperature of the main body 64 dropped to 45 DEG C, indicating about a 100% improvement. .
    [37] One of the advantages of enhanced cooling is that the crystallinity resulting from minimizing the reheating of the preform is reduced. The second benefit of the enhanced cooling applied directly to the outer surface of the preform is that this surface hardens faster and therefore exits faster from the center. Ejection timing is typically limited by the possibility of the outer surface of the preform to withstand damage due to scooping or the like, which may occur if the part is ejected when the surface is still relatively smooth. Enhanced air amplifier cooling reduces the time taken for the part to reach a safe discharge temperature, thus improving the overall molding cycle.
    [38] It was found that the positioning of the air amplifier 44 at different distances from the preform had a different effect on the surface cooling rate in the three regions studied—gate region 60, neck region 62, and body 64. . If only one air amplifier cooling station is used, the distance between the air amplifier and the preform compromises to optimize cooling in all three zones. However, if multiple air amplifiers used in each of the different index block stations are used, each is optimized to maximize cooling in one of these specific areas, thereby improving the overall cooling efficiency of the system. Such a system is shown in FIG.
    [39] Referring now to FIG. 5, one side of a fixture of an index type injection molding machine 10 is shown. As can be seen from this figure, three air amplifier stations 100, 104, 106 are installed. The first or upper station 100 is mounted on or on the top surface of the index block carriage 102. Station 100 may be moved away from and towards preform 12 by any suitable drive system known in the art (not shown). The second or rear station 104 may be mounted on or on the rear face of the index block carriage 102 and spaced apart from the preform 12 and similarly moved towards the preform. Any suitable means (not shown) known in the art may move the rear station 104 towards and spaced apart from the preform 12. The third or bottom station 106 may be mounted below the index block carriage 102 and may be moved to the preform 12 and spaced apart. In addition, any suitable means known in the art (not shown) may be spaced towards the preform 12 and the floor station may be moved to the preform. The third station unloads the preform 12 and deposits the preform on the conveyor 108. Any suitable means known in the art may be included to unload the preform 12 and deposit it on the conveyor 108.
    [40] As can be seen from FIG. 5, each of the stations 100, 104, 106 includes a plurality of air amplifiers 44. In the preferred embodiment, each of the stations 100, 104, 106 has the same number of air amplifiers 44 as the number of molded preforms that have been cooled.
    [41] One setup for the structure of FIG. 5 directs the upper station 100 to direct cooling air from the air amplifier 44 in the gate region 60 of the preform 12 to prevent gate crystallinity, which is the most prevalent position. It is to use. When the preform 12 is positioned opposite the station 100, a large amount of thermal energy in the body wall and the neck region of the preform does not move from the intermediate wall thickness to the surface, and a limited amount of cooling fluid in the region Headed. In each of the rear and bottom stations 104 and 106, the majority of the cooling air generated by the air amplifier 44 takes up the body and neck regions of the preform 12 to remove thermal energy from the large amount of preform moved to the surface. 64, 62).
    [42] In addition to the orientation of the cooling fluid relative to a particular area of the preform surface, variations in the amount of cooling fluid can also be used to more efficiently utilize the feed. In the upper station 100, little air is required for gate area cooling as compared to the rear and bottom stations 104 and 106 where high air flow rates are used to remove high thermal energy levels.
    [43] 6 shows how the air flow moves over the preform surface. Since each preform 12 is positioned on an injection molded core 16, each is mounted on its own forming structure, such as an index block 24, so that the air flow moving beyond the preform surface changes direction. It ultimately faces the mold surface 110. No air is provided in the hole to flow through this structure. Thus, as the path is blocked, the air flow must change direction and be spaced apart from the preform 12. The point where the air has moved away from the preform 12 is known as the separation point. This separation point 112 is shown in FIG. The occurrence of the separation point 112 at some point along the preform body reduces the efficiency of air cooling of the preform surface adjacent the neck end 62 of the preform body.
    [44] 7 shows an alternative example of a cooling system according to the invention. In this embodiment, the air removal attachment 200 is mounted to the air amplifier carrier plate 42. The deaeration attachment 200 includes a conduit 202 connected to the carrier plate 42. Conduit 202 has an inlet 204 adjacent to mold surface 110. The conduit 202 is connected to a vacuum source 206 such as a vacuum pump to vacuum the air from the mold surface 110 so that the cooling air stream emitted from the air amplifier 44 before separating from the surface is preformed 12. Make it reach farther along the body. It will be seen in FIG. 7 that the separation point 112 moves closer to the mold surface 110 (new separation point 112 '). If desired, valve 208 may be integrated into conduit 202 to convert a portion of the evacuated air into air amplifier 44. The recirculation characteristic allows the air amplifier 44 to optimize the supply of air.
    [45] 8 shows another alternative example of a cooling system according to the invention. In this embodiment, each air amplifier 44 is provided with an internal bore 220 having a sufficient internal diameter for the air amplifier to pass through the cooled preform 12. Each air amplifier 44 is mounted on the movable plate 42 'and extends beyond the length of the preform 12 such that cooling air is directed onto the surface of the preform during the movement of the movable plate 42'. Is moved. By adjusting the air amplifier inner diameter to suit the various preform outer diameters that can be molded, the cooling efficiency of the air stream can be fully optimized over the length of the preform surface. The plate 42 'and the position A from which the air amplifier 44 has been fully retracted from the position A to which the air amplifier 44 rests on the preform 12 are located in the art. Suitable means may be used.
    [46] Using the cooling system of the present invention, different types of preforms with some resin weight in various forms can be accommodated by adjusting the cooling profile of multiple air amplifier installations.
    [47] Although the air amplifier cooling technique of the present invention is disclosed using an index type injection molding machine platform, it can be used by removing parts from the molds and mounting them on conventional robotic instrument plates for post molding cooling treatment. In addition, downstream of the robot removal apparatus can be applied by integrating it into the downstream cooling installation.
    [48] It is clear that an air cooling system for preform molding is sufficiently provided in accordance with the present invention that the objects, means and advantages described above are sufficiently satisfied. Other changes, alternatives, and modifications will become apparent to those skilled in the art after reading this specification while the invention is described herein. Therefore, it is intended that such changes, alternatives and modifications be included within the scope of the appended claims.
