Abstract

In the present invention, there is disclosed an individual section (IS) machine comprising a plurality of individual sections (11) arranged in side-by-side relation. Each section has a section frame (11A) wherein the section frames (11A) are put on top wall of a bed (130). In said bed (130) below the top wall (134), there are performed rectangular openings (136) in the bed sides (132) for slidably receiving a plurality of seamless square fluid ducts (138), which extend the entire width of the machine. The top wall (134) has openings (140 142), which expose these fluid ducts (138) within each section (11) for creating a possibility to connect the ducts (138) through the openings (140, 142) performed in said bed (130) top wall (134).

Description

The present invention relates to IS machines (machines with individual sections) which convert molten glass batches into bottles in a two-step manufacturing process, and in particular it relates to the opening and closing mechanisms of the molds of the machine.

BACKGROUND OF THE INVENTION

The first IS machine was patented in US patents registered under Nos. 1,843,159 of February 2, 1932 and 1,911,119 of May 23, 1933. At present, more than 4000 IS machines from different manufacturers are used worldwide, producing more than million bottles. Such an IS (individual sectional) machine has a number of identical sections (a sectional frame in which and on which a certain number of sectional mechanisms are mounted), each of which has a front molding station that transforms one or more batches of molten glass delivered to the flasks having a threaded opening (bottle mouth) at the bottom, and a blow station into which the flasks enter and transform into bottles standing upright with the mouth facing upwards. The invert and hold ring mechanism comprising a pair of opposed arms that rotate about the invert axis, transfer the flasks from the front molding station to the blow station and, during the manufacturing process, invert these flasks from the position where the bottle mouths face downwards to a position in which the bottle mouths face upwards. The bottle made in the blow station is removed from the section by a takeout mechanism.

The front mold station comprises opposite pairs of front molds, and the final blow station contains opposite pairs of final molds. These molds are displaceable between open (separate) and closed positions. Opposite pairs of oral circular molds that are moved (carried near their tops) by the invert and hold mechanism of the circular orifices define the bottle mouth and maintain the formed flask during transfer from the front molding station to the blow station.

• ·

The front molds and final molds of said '159 patent are supported on inserts displaced by opposite carriers that are rotatable about a common axis of rotation in front of the molds (front to back movement is determined by the movement of the flask from the front molding stations to the blowing stations). The linear motor (liquid-actuated motor) controls the operation of both the front mold support mechanism and the final mold support mechanism. A linear motor for controlling the operation of the mold support mechanism is mounted at the front of the axis of rotation of the mold support mechanism and projects horizontally outwardly from the front of the section frame and a pair of link chains interconnects the output of the mold-side motor to the mold support mechanism. A linear motor for controlling the operation of the mold support mechanism is mounted vertically on the side of the axis of rotation (these mechanisms at each station are generally referred to as mold opening and closing mechanisms). This original IS machine has evolved into a machine in which motories (liquid-actuated cylinders or rotary-output motors) are located beneath the molds and each engine is coupled to an associated pair of mold carriers via transmissions that extend vertically from the bottom of the section at the front; the back of a pair of a molding mechanism (see US patents 4,362,544 and 4,427,431). The drive link couplings exert torsional forces which are undesirable on the carriers. In addition, the drive linkages must be designed with respect to the specific mold form, and therefore both the entire linkage and the mold support mechanism require related changes when switching from processing one batch of molten glass to processing another batch of molten glass. In such machines, the front camera shutter mechanism and the funnel mechanism must be located on the side of the section near the device, making it difficult to maintain and repair these mechanisms, and forcing adjacent sections out of service. In these mold opening and closing mechanisms, there is nothing to block the molds at the necessary mold closing positions during the formation of the flask, as a result of which the mold halves can detach from each other and cause an increase in the vertical seam on the flask and hence on the finished bottle. To avoid this, the articulated connections must be designed to prevent the molds from opening in the closed position (see U.S. Patent No. 5,019,147).

• · ·· · · ··

The embodiment of the IS machine described in U.S. Patent No. 4,070,174 is called the AIS machine. In this machine, which is still sold today, the mold holding mechanism pairs are mounted to perform axial ("A") motion instead of rotary motion, with the respective motors controlling their operation in the usual manner. The machine, which is derived from the IS machine, has the name ITF machine and is described in US Patent No. 4,443,241. This machine, which has three molding stations [front, reheating and blowing or triple forming "TF"], was not successful. In this machine, the engine for the pairs of front and blow mold carriers was a vertically directed linear motor that was located just below the center of the molds. This machine also moved axial front and blow mold halves.

Such mold opening and closing mechanisms are quite complex, containing a very large number of components, which are specially designed for a specific machine configuration that occupies a significant portion of the frame or section box. Because of this, these mechanisms are very costly and often changing the specific arrangement of the machine under operating conditions requires a rebuild of the machine by replacing the entire mechanism. This in turn makes it difficult to assemble the necessary tubing for the section mechanisms. The working air has to be supplied in tubes in front of, behind or at the top of the section frame, and such a pipe distribution is then very expensive. In addition, a major problem with IS machines is that the increase in dimensions due to heat on the mold side is reflected towards the axis of the invert and hold ring mechanism, while the increase in dimension due to heat on the blow mold side is reflected away from the axis of the turning and holding a circular orifice. Finally, the effect of the force will not be transmitted directly to the mold-bearing intermediaries because the carrier carrying these intermediates is in the force path, so that these intermediaries may be subjected to the twisting forces when the clamping load is applied.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide an improved mechanism for opening and closing molds.

Accordingly, it is an object of the present invention to provide an IS machine having an improved airflow system for individual sections.

DETAILED DESCRIPTION OF THE INVENTION

The IS machine comprises a number (usually 6, 8, 10, or 12) of the sections 11. The conventional section takes the form of a box frame or a section cabinet 11A (Fig. 2) which includes or supports the section mechanism. Each section comprises a front mold station having an opening and closing mechanism 12 for transferring the front molds in which the delivered molten glass batches are converted into flasks, and a final station having an opening and closing mechanism 13 for controlling the final molds into which the flasks enter. , which is then transformed into bottles. One, two, three or four batches of molten glass may be processed in one cycle of each section, and therefore, depending on the number of batches of molten glass being processed simultaneously in said one cycle, each machine will be appropriately referred to as a single molten glass machine, two machine. a molten glass batch, a machine for three batches of molten glass (shown embodiment) or a machine for four batches of molten glass. The takeout mechanism (Fig. 40) removes the made-up bottles from the end station and transfers them to the outage 14. The unloading mechanism (not shown) subsequently transfers the made-up bottles from the outage 14 to the conveyor 15, which transports them away from the machine. The front of the machine (or section) is the end which is farther from the conveyor, the rear of the machine being the end which is located near the conveyor, and the sides and the machine or sections are perpendicular to said conveyor. Side to side movement is a movement that is parallel to the conveyor guide.

Giant. 2 shows part of a section 11 of a machine for three batches of molten glass produced according to the resulting conclusions of the present invention and is a schematic illustration of the design of a front mold station. The section 11 comprises a casing-shaped sectional frame 11A having a top surface 134 with an upper surface and side walls 132. Each mold opening and closing mechanism comprises an opposed pair of mold holding mechanisms 16. Each mold holding mechanism is coupled to a control assembly means comprising a linear transmission rotary positioner 18 mounted on top of the section frame 11A and driven by a control system 19 having a rotary output to move the associated mold holding mechanism 16 in a lateral direction between the retracted , a separate position and a retracted position in which the halves of the opposite pair of mold holding mechanisms are firmly pressed together. The mechanisms for holding the molds of the front mold stations are the same, but the mechanisms for holding the molds of one station may differ in size from

a mechanism for holding the molds of another station as a result of differences in the manufacturing process which will be well known to those skilled in the art. Since the machine being shown is a machine for three batches of molten glass, each mold holding mechanism of the front or end station will carry three half 17 molds (front molds or final molds).

Referring now to Figures 3, 4 and 5, the attachment of the mold-holding mechanism to the associated drive system will now be described, and the means for moving the mold-holding mechanism between the retracted position and the retracted position will now be described. Giant. Figures 4 and 5 show only a mold holding mechanism that carries a mechanism associated with a single section, while Fig. 6 shows an alternative housing that carries two mold holding mechanisms when two sections adjoin each other and which only one mechanism for holding the molds when there is no section. The control system 19 comprises a servomotor 66 (with some gear and / or reversing gear) having a rotary output in the form of a spindle 67 (FIG. 4) which is connected to a lead screw 70 (e.g. spherical or trapezoidal) having an upper part with The housing 90 carries a lead screw 70. Both ends of the lead screw are positioned in the housing 90 in a vertical position in suitable, simple radial or double ball bearing assemblies 99. The housing has a pedestal portion 93. which is bolted to the upper surface 94A, 94B (FIG. 6) of two adjacent section frames (if no adjacent section is attached, the top wall of the section will be extended outward to form a more perfect base for the cabinet) with suitable screws 95, opposite side walls 96 that comprise stiffening ribs 97, and a removable upper portion 98. The lead screw is coupled to a rotary linear transmission positioner comprising nut means having a lower left-hand threaded nut 72 and a right-hand threaded upper nut 74 and positioned on said lead screw. In addition, the rotary linear transmission positioner comprises means for attaching nuts 72, 74 to the mold holding mechanism, wherein the first pair of lifting members 76 are connected at one end to the upper nut 74. the other pair of lifting members 78 is connected at one end to the lower nut 72 and the yoke 82 has a horizontal bore 91 carrying a foamed, horizontal rotating shaft 80 to which the other ends of the lifting members 76, 78 are pivotally attached (sleeve or flange bushings are used to extend the life of said links). The yoke 82 also has a vertical bore 92 into which the vertical rotating shaft 27 of the mold-holding mechanism is rotatably entered. As a result, the rotation of the guide will be ·· • ·· • ·

The screw 70 in one direction subsequently pushes the mold-holding mechanism towards the opposite mold-holding mechanism and vice versa. It can be seen that the lifting members 76, 78 form articulated joints that can move between a stowed and a retracted position and that operate horizontally between the housing 90 and the mold holding mechanism.

Each mold holding mechanism has a carrier 30 and lower and upper intermediary members 24 that hold the mold halves and which are supported on the carrier 30 on a shaft 27 that passes through vertical holes in the carrier 30, the intermediate members 24 and the yoke 82. The yoke 82 enters the pocket 101 in the carrier 30. It can be seen in the figures that the lead screw is vertical and is guided near the mold holding mechanism, with the linear transmission positioner connecting the rotary output of the actuator (lead screw) and the mold holding mechanism compactly positioned between the guide a bolt and a mold retaining mechanism on the upper surface of the top wall 134 of the section. The linear transmission rotary positioner is completely positioned above the top of the section frame and creates a load near the center (vertical and horizontal) of the mold holding mechanism [vertically because the axis of the horizontal shaft 80 lies midway between the upper intermediate link 24 and the lower intermediate link 24 and , the axis of the vertical shaft 27 passes through the center of the body of the carrier 30 (and the intermediate elements 24)]. The load that is transmitted directly from the vertical shaft 27 to the upper intermediate member 24 and the lower intermediate member 24 acts in a plane perpendicular to the mold contact plane that intersects the mold center (middle mold center or, if there is an even number of molds, middle distance between mold centers). The direction of application of this load is perpendicular to the contact plane (clamping plane) located between opposite mold halves a, since the vertical rotary shaft 27 rotatably supports the two intermediate links 24 and the yoke 82, and this yoke additionally rotatably supports the horizontal rotary shaft 80 which is connected to the lifting members, the intermediate members 24 are not subjected to any torsional forces during the application of the clamping load. Accordingly, the force exerted by the rotary positioner linear transmission will be transmitted directly to the intermediate elements 24 - the carrier 30 is not in the load gripping path.

Both nuts 72, 74 have a flat, rear abutment surface 84 that is associated with a flat, machined, vertical abutment surface 86 that is defined on the rear wall of the transmission housing (casting) 90. When the mold-holding mechanism is withdrawn, the rear abutment surface of the nuts 72, 74 is separated within a predetermined distance (clearance) from the vertical abutment surface 86 which is defined on the wall. The lead screw 70 meets the strength requirement so that during the insertion of the mold holding mechanisms up to the gripping contact

of the opposite mold halves, when subjected to the desired load, brought the nut abutment surfaces 84 as necessary into contact with the abutment surface 86 of the rear wall. The lead screw housing 90 has the necessary strength to ensure that this load can be applied and that the removable top portion 98 can be adjusted prior to mounting in place to adjust the desired clearance between the nut bearing surfaces and the wall bearing surface. Accordingly, the mold halves, the mold holding mechanisms, the oppositely positioned transmissions, and the sleeve 90 define a truss beam (made of triangular structures) that is supported above the upper surface of the section frame to prevent both vertical deflection (the truss will thus protect the support shafts. prior to the downward load) and the separation of the mold halves laterally (horizontally) as a result of the vertical loads applied during the molding process. To provide lubrication of the support surfaces 84, 86, an oil groove 100 may be formed in the rear wall surface 86, and oil may be introduced into the groove through suitable passages in the lead screw housing 90. In order to minimize friction, the machined surface may be impregnated with a solid lubricant. To provide greater strength, the lead screw housing 90 (FIG. 6) can be doubled to carry additional lead screws that will be attached to the rotary positioners of the linear transmissions of adjacent sections.

Each intermediate member 24 (FIG. 7) comprises a first portion 26 which rotates about a vertical rotary shaft 27 and which carries one of the mold halves and a second portion 28 which carries the other two mold halves and which is connected via a pivot pin 29 to the first of the portion 26 in such a position as to ensure that the effect of the forces on each mold is evenly distributed. The pivot shaft 27 slides downwardly through the first portion 26 of the upper intermediate link 24, through the upper wall 30A of the carrier 30, through the transmission yoke 82, through the lower wall 30B of the carrier 30, and finally through the first portion 26 of the lower intermediate link 24. extending downwardly through the upper intermediate member 24, through the carrier 30 and through the lower intermediate member 24, have a predetermined clearance relative to said intermediate member portions to define the desired movement of their first portion 26 and second portion 28.

The mold-holding mechanisms are, as will now be explained, designed for sliding movement on two parallel shafts 40, 50. The carrier 30, whose position is parallel to the clamping plane, has an outer one at a certain distance from the invert mechanisms and holding the circular orifices - FIG. 8) a mounting flange 32. This mounting flange is secured by suitable fastening means 34 to a block 35 having a corresponding slot 38

- 11 ·· ·· · · · · · · · · · ·. 11 11 for fitting said flange and having a flat, horizontal, abutment surface 36 for taxiing on a flat, horizontal, abutment surface (track) 41 delimited on a square shaft 40 which is a square and which is part of a bracket 42 attached to the section frame near its end (the bracket 42 could possibly be formed as part of the housing of some other mechanism). The wipers (not shown) will keep the track surface clean and the grease can be supplied to the block so that the bearing surfaces can be continuously lubricated. The inner (adjacent to the invert and throat retaining mechanism) end of the carrier 30 is secured by suitable fastening means 34 to the L-shaped block 46, which is integral with the supporting block 48, and has a cylindrical abutment surface sliding on a corresponding cylindrical support surface of the shaft 50.

The reversing and holding mechanism 110 of the orifices (FIG. 8) is mounted on the top surface of the section box between the front station and the end station. The mechanism has a pair of opposing holders 112 that can be moved from a separate position to a shown closed position by the operation of the respective horizontally positioned pneumatic cylinders 114. These orifice holders carry oppositely the 115 orifice ring halves that close the bottom of the molds when the mold halves are which, when the mouth rings are closed, determine the shape of the mouths (threads) of the 116 individual flasks and finally the bottles. After forming said orifice shape, the orifice holders 120 rotate 180 ° due to the operation of the invert and hold mechanism of the orifice actuated by the servomotor 108 to rotate the worm drive shaft (not shown) guided in the worm block 118 in which the rollers 114 of the reversing and retaining mechanism of the orifices are suitably fastened between oppositely positioned vertical supports or brackets 122 and said worm gear cover. The vertical worm block 118 and the inverting bracket 122 are attached to the upper surface of the section frame.

Referring now to FIG. 8, the annular shaft 50 of the mold opening and closing mechanism, which is located near the invert and hold mechanism of the circular orifices, is mounted at each end in opposite, inverting brackets 122. The book shaft of the opening mechanism and the closing of the final molds takes the form of a two-part book shaft 50A. 50B. These shafts are mounted coaxially and each is mounted at one end in an inverting bracket 122 and at the other end in a vertical worm block 118.

Regardless of whether it is a front mold station or a final mold station, the square shaft 40 allows the carrier to expand in the same direction away from the turning axis (center of the section) due to rising temperature.

9-11, two ring shafts 50C may alternatively be mounted directly on carrier 30. The free end of these shafts slidably into suitable bearings 170 (FIG. 10) in respective holes 171 formed in a pair of mounting blocks 172 that they are designed to be integral with the lead screw housing 90. Each mounting block has a pair of vertically spaced bearings 170 spaced apart by one another, into which SOC circular shafts enter from the mold holding mechanisms of adjacent sections. Each pair of circular shafts belonging to a section (one above and the other below) is positioned vertically one above the other above and below the axis of the horizontal, yoke swivel shaft 80. Because expansion of the drive block due to temperature increase is not as great as thermal expansion of carrier 30 , an alignment mechanism is incorporated into the carrier, so that regardless of whether it is a front mold station or a rear mold station, the carrier will expand further from the center (turning axis) of the section due to temperature increase. It can be seen in Fig. 11 that the bolt 174 connects the pin 176 on one side of the support 30, which can slide horizontally in the longitudinal pin path 177, with the outer circular shaft 50C on the other side of the support. Holes 178 and 179 in the carrier to which the respective shaft enters and the bolt have the necessary clearance to facilitate the sliding of the pin horizontally in its path (relative) and thereby allow the circular shaft to maintain parallelism with another circular shaft within the ambient temperature range.

In both the embodiment shown in Fig. 8 and the embodiment shown in Figs. 9 and 10, each support is located on a circular shaft extending between the pivot axis and the center of the mold opening and closing mechanism, positioned on the other side of the center of the opening mechanism. and closing the molds on the axis, which can transmit the effect of expanding the material due to the increase in heat further from the axis of the invert and hold mechanism of the circular orifices. That is, the expansion due to the heat of both the final mold station and the front mold station will proceed in the same direction (further away from the axis of the invert and hold mechanism of the orifices). This has never been achieved before. In all known IS machines, the effect of thermal expansion in the case of the front mold station side was directed towards the mechanism for turning and holding the circular orifices, while in the case of the final • 0 «0 ·

In this regard, the thermal expansion of the front station and the rear station is guided in the same direction as the circular orifice holder, allowing better alignment of the machine working direction.

Giant. 12 shows the cover structure of one of the lead screw bushings. It can be seen that the carrier is fully retracted. The cover has a front, sloping wall 52 that covers the top of the carrier 30 and is attached to the rear top edge by a hinge 53. The cover also has flanks 54 that are integral with the wall 52 along both edges 56 in the top. Each flank has a vertical portion 57 that covers a respective portion of the carrier in its retracted position. The flap actuator 58 in the form of a flap 58, which is attached to the leading edge of the top portion 98 by a hinge 60, rests on opposite inwardly guided brackets 61 which are attached to the sloping front wall 52 of the cover. In the retracted position, the top edge of the kiytu is near the hinge 60. When the carrier is pulled away, the top of the housing (and the flap) will move to a slightly sloping position, and the flap and top will move appropriately to accommodate displacement.

The operation of transmissions of the mold opening and closing mechanisms located above the top wall of the sectional frame, and the operation of transmissions driven by electronic motors mounted so as to be directed downwardly from the top wall of the sectional frame, open the floor section of the sectional frame. a frame which is filled in a known manner with these motors (pneumatic cylinders) and transmissions (couplings). The sectional frames 11A of the machine (6, 8, 10, etc. may be) are located on a pedestal which is delimited by a number of two-piece beds 130 which are connected to each other. Each two-piece bed has passage means extending from one side to the other side of the bed following rectangular apertures 136 in the bed sides 132 separated by side wall ribs 137 for sliding entry of a plurality (eight in the preferred embodiment) of seamless, square conducting fluids that extend through the entire width of the machine. These pipes are used for pneumatic control, air cooling, lubrication and vacuum generation, etc. as required. The top wall 134 has apertures 140 for the front mold station and apertures 142 for the final mold station, through which apertures 140, 142 extend through said fluid inlet 138 to each section box. Sectional cables and conduits are routed below said conduits and extend upwardly through the space between the plurality of conduits and through the conduit passages 145 formed in the top wall 134 so that they can be connected to the individual mechanisms.

Pipes 138 that extend from one end of the machine to the other and which are connected to respective sources are releasably attached to each two sectional beds by means of a clamping structure (Fig. 14) comprising an I-beam 147 supporting all pipes and clamping device 148 at the front and rear of the bed, the fastening device being attached between the I-beam and the top wall of the bed. Each clamping device has a control screw 149 having a tightening head 151 and which secures the pipe 138 through the respective apertures 153 it inserts. Turning the control screw in one direction presses the conduit against the side wall ribs 137 and lifts them upwardly into firm contact with the rib 143 that projects downward from the top wall 134 of the two-piece pedestal. If it is necessary to remove one of these pipes and replace them with, for example, two pipes, the clamping mechanism is released by rotating the tightening head in the opposite direction, thereby releasing the pipe to be removed and subsequently slidable and replaced by several other side-by-side pipes. be added or removed according to a predetermined number (depending on the requirements of the manufacturing process).

Referring to Figs. 15 and 16, it will be explained that each motor of the mold opening and closing mechanism operates in a known manner where feedback signals are transmitted to a motion controller that controls servo amplifiers that control motors (servomotors). As can be seen, motoiy are electronically coupled to each other. Motor / encoder number 1 (control) M1 / 154 monitors the request signal from motion controller sequence 150 of motion controller 155. Motion feedback position processor 152 that receives a digital feedback signal of encoder part motor / encoder number 1 sends a signal to the summation circuit 156. The summation circuit transmits to the control signal processor 158, a digital signal that passes to the amplifier 160 that controls the motor / encoder number 1. The motion controller sequence receiving device receives the signal from the summation circuit 156, processing it into a request signal followed by sending to the second summation circuit 161, which also receives a feedback signal from the position feedback processor 162, which receives the digital feedback signal from the encoder portion of motor / encoder number 2 (M2 / 168), and transmits the digital signal. This signal is converted by the second amplification control signaling processor 159, which transmits the signal to the second amplifier 162, which controls the operation of motor / encoder number 2 (slave) 168.

Separation of mold halves with complete withdrawal of mold carriers (each in initial position) can be predetermined and the ideal center point of mold movement is half ·· ··

-15 distance between them. The initial step of the feed program is that the position controller 150 determines a displacement profile that will control the operation of the motors (M1, M2) electronically coupled to each other to move the molds associated with these motors to said ideal midpoint. To confirm the completion of the transfer of the two mold carriers, each engine speed test is performed, and if one engine speed (VM1) and the speed of the other engine (VM2) equals zero, the next step in the feed program begins by determining the sequence controller a velocity profile that will control the operation of the engines at a very low speed (Vs) - (this may be any command that sets the motor into action). When the actual speed of each motor equals zero again, a determination is made as to whether the actual end position of the extruded mold carrier is within the acceptable error range (+/- "X" from the ideal midpoint). The encoder associated with each motor provides data to determine the actual end position. When the mold carriers are in an acceptable position, a third feeding program step can be performed, wherein the operation of each engine generates a selected torque over a specified period of time ("TI") that can be adjusted via a computer. This period of time is the time when the mold halves will be clamped together. After this time has elapsed, each mold carrier returns to its "0" position, or the initial position. In order to return each mold support mechanism to the initial position, as shown, each motor is operated at low speed - VS, with a minus sign indicating rotation in the opposite direction (which can be set - the arrow represents the computer input) for a limited time T2 (which can also be adjusted - the arrow represents the computer input) into the "burst" molds before the mold holders are pulled to the "0" position at high speed -VR (opening profile - for example, a steady acceleration section followed by a steady deceleration section) ending in the starting position).

A second algorithm for controlling two servomotors is shown in Fig. 15A. In this embodiment, the motion controller has a sequence control device for each motor. Therefore, the motors are not electronically coupled to one another. As shown in Fig. 16A, each motor is controlled to simultaneously move the respective mold holder according to a predetermined feed profile (displacement / velocity / acceleration profile) to the ideal center position (one half of the total distance plus the selected distance resulting in be gripping opposite mold holders with subsequent stopping). The fact that both mold holders have stopped is verified (error signal can be monitored) and the actual position of each mold holder

- 16fora is determined and compared to the ideal midpoint position. If the actual position of each mold holder is within +/- X of the ideal midpoint position, the feed is acceptable. If this is not the case, an error signal will be produced. The actual center point is determined (the total distance of travel of the two mold holders divided by two) and a new ideal center point is determined. If one mold holder has moved over a longer distance than the other mold holder (over a longer distance than the acceptable difference), the control determines the extent of adjustment of the feed profile of one of the engines, which either accelerates relocation or slows relocation to reduce distance difference, which both mold holders undergo. Then, the control device will provide the required torque to the motors and will continue the program shown in Fig. 16.

Giant. 17 shows a bolt head mechanism 180 mounted on the top wall 134 of the sectional frame 11A. A carrier arm 182 that carries the three bolt heads 184 (the bolt head mechanism is shown schematically because of a wide variety of specific designs) is attached to the vertical control bar 186. This control bar will be raised and rotated during the time it is in the uppermost lift section so that the breech heads can move between the raised, retracted position and the time retracted position at the top of the front forms. This mating displacement is controlled by the operation of a servomotor 188 (FIG. 18) having a rotary output 190 which is connected via a coupling 192 to the bolt 194. The thread of this bolt corresponds to the thread of a nut 196 that rotates freely in a hole 198 formed in the cam housing 199. The roller follower 202 travels along the drum cam 204 formed on the cam housing wall 206. The vertical control bar 186 is mounted on top of the nut. Referring to FIG. 17, the cam sleeve has a pedestal 208 which is secured by screws 209 to the top wall 134 of the section frame 11A at its front corner formed by the side wall 132 and the front wall 135. In the retracted position of the front molds and these axes are connected to the top of said front molds. Upon actuation of the cam, the breech heads first lift partially above the front molds and then, as they move upward over the remainder of their transfer path, these breech heads move further away from the centers of the front molds so that the invert and hold mechanism of the book mouths can displace flasks to final forms. The bolt head mechanism may be located at the front of the sectional frame at each corner and, in contrast to the hitherto known bolt head mechanism, the fully raised and retracted bolt head arm may generally be located within the section space as shown in Fig. 17, and it does not have to extend beyond the adjacent section.

The closure head (FIG. 19) has a body 248 that includes a cup-shaped portion 250 having a circular inwardly tapered sealing surface 252 that extends around its open base for contacting and sealing a corresponding surface 254 on top of the open front mold. The body 248 also includes a vertical tubular housing portion 256 which defines a cylindrical guide and support surface 258 for sliding inlet of the rod 260 of the piston member 262. The cylindrical head 264 of the piston member 262 has an annular sealing surface 265 that can slide in the hole 266 of the portion 250. in the shape of a cup. A spring 268 positioned around the vertical, tubular housing portion 256 is compressed between a flange 270 which is detachably attached to the carrier arm and also attached to the piston rod 260 and the top of the cup-shaped portion 250 to maintain the upper surface of the cylindrical head 264 in contacting the adjacent surface of the cup-shaped portion when the breech head is separated from the front mold.

20, the actuator (FIG. 23) moves the flange 270 downward until the top of the flange is at a first distance D1 from the top surface 272 a front mold to which the cylindrical head will be lowered relative to the cup-shaped portion to define the necessary clearance "X" between the lower circular surface 274 of the cylindrical piston head and the upper surface of the front mold (the cylindrical head has moved relative to the cup-shaped portion to vertical distances "v"). This generates the required compression force between the piston member and the front mold to create the necessary seal between the contacting, inwardly tapered surfaces 252, 254. In this situation, the settling air introduced into the front mold through the central hole 276 in the piston rod will pass through a number of radially guided holes 278 in the cylindrical head into the corresponding number of vertical holes 280 and through the annular gap between the circular lower surface 280 of the cylindrical head and the upper surface 272 of the blank mold into the final mold (suitable holes that connect the interior of the body with the atmosphere) relation to the body). After the settling blowing has finished and the molten glass batch has been converted into a bulb, the flange is displaced until its top is at a second distance D2 from the upper surface of the blank mold. As a result, the lower book surface 281 of the cylindrical head comes into firm contact with the upper surface 272 of the blank mold and this front surface.

- 18form closes. In forming the flask (by filling the inner cavity delimited by the inner surface of the front mold and the lower surface of the cylinder head), air may escape through a number (four in the preferred embodiment) of small notches 286 formed in the lower circular surface 281 of the cylinder head (Fig. 22) into the vertical holes 280 then through the radial holes 278 into the piston rod hole 276 and out through the now released holes 290 into the space between the top of the piston and the cup-shaped portion 250 and away from the relief holes 282.

If it is desired to use a funnel mechanism 210, then this device may be mounted in another front corner. Na ohr. 24, it can be seen that the design of the breech head mechanism and the funnel mechanism are the same except for the direction of the drum cam and except that the funnel carrier 212 carrying the three funnels 214 is located on the other control rod. Like the breech head mechanism, the funnel mechanism can always be located in the space of its own section.

Giant. 25 shows an alternative mechanism 110 for reversing and holding circular orifices. As can be seen, this invert and hold ring mechanism can be used in the embodiment shown in FIGS. 8-10. The end of each orifice holder adjacent to the worm gear housing 120 has the form of a groove fastening bracket 113 having its bayonet end. 109 is slidably mounted on a support bracket 117 which is attached to the inverting roller 114. The annular outer end 119 of the roller 114 (FIG. 26) slidably enters a corresponding annular groove 121 at the top of the respective outer side bracket 122A. The threaded end of the proximity switch or proximity sensor 124 is screwed into a corresponding hole 125 in the side console and secured by a nut 126 at a location where it detects the cylinder in its fully inverted position (the orifice holder is retracted). The proximity switch cable 128 is routed downward in a through hole (not shown) in the side console, and the proximity switch itself is protected by a cover 129. A further pair of proximity switches 124A is located on the console 131, which is attached to the worm block 118 (Fig. 27). ). These proximity proximity switches are located below the worm gear housing 120 and each is directed to a respective cylinder of a pair of cylinders. At the end of each cylinder adjacent to the worm gear housing, a semicircular target 133 is attached to indicate to the respective proximity switch the displacement of the cylinder to the worm gear housing from the position that was the first position of the orifice holder in which the circular mouth halves were carried 9

- by a ring-shaped holder at the top of the plunger mechanism (180 ° inverted starting position), to a second position (180 ° back from the first position) in which the oral ring halves hold the flasks at the final blow station (0 ° inversion end position). In this context, the terms "mouth ring open" and "mouth ring seized" will be used to describe the position of the ring mouthpiece / bracket / cylinder, and the control functions will be described with reference to one ring mouthpiece because the other ring mouthpiece is controlled in the same way. . Since the servomotor 108 has an encoder that generates positional feedback, the angular position of the orifice holder is known throughout its angular displacement range.

The algorithm shown in FIG. 28 will identify control difficulties during inversion. The " mouth ring closed " sensor 124A will be continuously monitored for as long as the actuator 108 moves the worm, worm gear, and mouth ring from the initial turning position (180 °) to the end turning position (0 °). If the oral circle does not maintain its closed position throughout these 180 ° displacements, a warning signal will be sent. This signal either stops the operating cycle or triggers the necessary smaller range intervention.

The algorithm shown in FIG. 29 will determine whether the time of the oral ring's arrival at the open position is constant. The oral ring actuator cylinder will be actuated according to the determined cycle timing (time "T") to move the oral ring from the closed position detected by the sensor 124A on the worm block to the open position detected by the sensor 124 on the side console. The time between these two signals is measured as, "AT" and compared to the ideal time difference (original time difference) and the time "LT"), which is the difference between the actual and ideal time interval is sent to the control device that controls the operation of the control cylinder. oral circle. If the T error is greater or even erroneous, a signal will be sent to provide the necessary intervention, from stopping the cycle to sending a warning message to the operator notifying the need for maintenance.

Giant. 30 illustrates a reversible algorithm. The mouth rings will be opened at the end station to release the finished bottles, and before the arm can rotate 180 ° to the front station, the control device must verify that the mouth rings are in the open position. In connection with this verification, the reciprocating servomotor will be controlled to provide the necessary angular displacement. At the selected angle of rotation (ideální1 ideal), the control device will control the operation of the orifice ring so that it moves from the open position to the closed position

-20positions. Such action will be determined by certain limits, which stipulate that Θ1 must be greater than X ° and that the movement of the oral circle must be completed after reaching Y °. The values X, Y and θ1 are independently adjustable. The control device determines the actual angle (01 real) when the mouth ring detection sensor 124 is open, and determines 01 the deviation # 1 by subtracting 01 actual from 01 ideal. This deviation is sent to a control device for correcting the position in which the orifice ring is actuated. If this deviation is excessive or even incorrect, a warning signal is sent.

In addition, the control monitors the situation where the oral circle takes a closed position defining an angle Θ2 of real and the sensor detects the status of the "oral circle closed". The cylinders are conventionally controlled by air and the time it takes for the pneumatic cylinder to move from the "ring open" position to the "ring closed" position depends on the specific technical conditions of the roller's operation. As the performance of the cylinder decreases, the required displacement time increases, and such a delay may cause the moving structure (oral ring structure) to strike the front molds that would normally be beyond its reach. The control device determines the second Θ1 deviation (Θ2 ideal minus Θ2 actual) and performs a second correction of the angle of action of the oral circle. When this drop reaches a predetermined angle that is limiting for the necessary intervention, the control device sends an appropriate signal to indicate the need for repair and / or maintenance. Since each angular displacement is a function of time for the encoder, these deviations will be related to the observed time differences. These variations ensure that the cycles still have times.

The mouthpiece mechanism, which is part of the front station of the section, is shown in Figs. 31 and 32 and includes, as can be seen, three mouthpiece canisters in the case of a machine for three batches of molten glass. Each plunger canister has an upper cylindrical portion 63 and a lower cylindrical portion 64 with pin protrusions 65 carrying O-ring seals 71 and an exhaust manifold 73 that extends axially downwardly from the lower surface 75 of the lower cylinder to connect the plunger canister to the necessary operational services. [cooling of the plunger, gas evacuation, plunger plunger, plunger plunger, puff / undercoat (in blow molding machines) or plunger cooling (in press blow molding machines), lubrication, prop support]. The canister can evacuate gases through the upper cylinder, in which case the manifold and associated exhaust pipe will not be required. For the sake of clarity, the mouthpiece mechanism will be described * · ·

-21 in connection with a blow molding machine, but in those passages where the pre-pressure / vacuum is mentioned, it should be understood that it is a cooling of the punch in a press blow molding machine. Mounted at the top of each upper cylinder is a mounting plate or flange 77 and a tooling 79 having opposite ears 81 for engaging opposite halves of the mouth ring when the mouth ring holders are in the closed position. These mounting plates 77 are secured to the upper surface of a mounting block or plate 85 having openings 87 (FIG. 33) through which the upper / lower rollers can pass, by suitable fastening means, and this mounting block is fixed to the upper surface 94 of the section frame 11. The upper surface of the sectional frame has a large opening (not shown) into which the plungers can be placed, depending on whether it is one, two or three batches of molten glass. In this context, the top surface 94 of the section frame is the control surface. It is appropriately machined at those locations where the mounting block is attached to create an accurate horizontal substrate. The upper surface (or area or substrate for mounting the flanges) and the lower surface of the mounting block are appropriately machined to be parallel, and the height of the mounting block corresponds to the location of said tooling at the desired height. By defining the position of the cylindrical apertures 87 in the assembly block sufficiently precisely to align the constituent diameters of the canisters, the axes of these canisters will assume the necessary position upon insertion. By placing the diamond and circular pins (not shown) on the top wall of the section frame and defining suitable holes in the lower surface of the mounting plate, the mounting plate is automatically mounted. Since the top of the canister is attached to the top wall of the Sectional Frame, the effect of thermal expansion will not significantly affect the position of said tooling.

The first four fluid lines routed below the front mold side of the section (Fig. 34) are the pneumatic gripper sinkers (line 30 - about 3.1 bar), the pre-flow (line 302 - about 2 to 3 bar), vacuum (line 404) and mouthpiece pitch (pipe 306 approximately 1.5 to 2.5 bani). These operators are connected through openings in the top walls of the ducts to the vertical inlets 308 in the lower surface 310 of the plunger distributor 312 through the corresponding passages 314 in the connecting plate 316. The four pneumatic operators are routed through the plunger distributor into outlet ports 320 in the front face of the plunger distributor. pedestals. The fifth fluid line 301 extends below

-2244 • 4 bottom wall of the front mold station of the section (fig. 34) and supplies lubricating fluid. The lubricant passes through an opening 303 in the top wall of the lubrication line, then continues through a passage 311 in the connection plate to the lubrication inlet 305 in the lower surface of the plunger that provides lubrication through the outlet opening 309 in the front face. The O-rings 318, which are pressed between each surface of the connector plate 316 and the outer surfaces of the duct and the lower surface 310 of the plunger, provide an effective seal by screwing said plunger into the bottom wall of the section frame. A transverse aperture 322 is formed in the plunger manifold into which a shutter cylinder 324 is actuated by a crank 323, which can be rotated from an open position in which pneumatic operators and lubrication can pass through holes 325 into the outlet openings, into a closed position. in which the passage of pneumatic operators and lubrication is closed.

Connected to the front face 321 of the plunger manifold is a junction box 330 (Fig. 35) that includes five servicing inlets (320A, 306A) on the rear face that are connected to the plunger manifold service ports 320 and 309 (O-rings) 326 provide a seal). The described embodiment is a machine for three batches of molten glass, which means that the front station of each section comprises the three plunger canisters shown in Figure 32, which are the inner plunger canister (located closest to the axis of the invert and hold mechanism), a middle gin can and an outer gin can. Each individual pneumatic service input (plunger pitch, vacuum, pre-flow, plunger plunger) and lubricant line in the junction box is divided into three outlets, one for each plunger canister. On the left side of the front face 332 of the junction box are, for the purposes of the inner canister, the middle canister and the outer canister (vertical arrows "inner canister" etc.) indicate vertically arranged groups of openings in the front face that belong to a specific canister and horizontal arrows "canister" etc. indicate three groups of orifices associated with a particular service function) located three outlet ports 334 for operating the plunger climb function associated with a single plunger inlet opening, three exhaust ports 336 that are connected to the exhaust, and three inlet ports 338 "Canister", which communicates with three corresponding outlet openings defined in the rear face of the junction box (not shown) and communicating with the corresponding "mouthpiece lead" inlet openings 360, which are defined in the front face 321 of the plunger (fig. 37). Flow inside each vertically arranged group of holes on this left side »· ··

-23Can be controlled by a pressure adjusting device such as a regulator / valve and a sump tank (not shown for clarity) that will be connected either to the "canister" line of the operator of the plunger climb function or to the exhaust. On the right side of the front face of the junction box (Fig. 35), three service outlet ports 340 for vacuum, related to a single vacuum inlet port, three pre-discharge ports 342 for single, inner, center, and outer grout canisters are provided. an inlet opening for operating the pre-blow, three "canister" inlet openings 344 that communicate with three corresponding outlet openings located in the rear face of the junction box and communicating with the corresponding "pre-vacuum / vacuum" inlet openings 364 defined in the front face 321 of the mouthpiece the manifold base (Fig. 37), and three exhaust ports 346 that are connected to the exhaust. In this case, the regulator and the valve (not shown) operate in combination with a valve that is controlled by the actuator (not shown) to ensure that the inlet openings are "connected to the canister" either to vacuum or to the pre-blower or to the exhaust. On the right side of the top face 348 of the junction box (Fig. 36), three inner plunger service exit ports 352 are provided for inner, middle, and outer canisters that are associated with a single plunger lower service entrance port, three inlet ports 350 communicating with the three corresponding outlet openings delimited in the rear face of the junction box, which communicate with corresponding plunger inlet openings 362 delimited in the front face 321 of the plunger (FIG. 37), and three exhaust openings 354 which are connected to the exhaust. The flow in each vertical group of openings is controlled by a separate regulator and valve (not shown for clarity) that will connect the line "to the canister" either to operate the plunger drop or to the exhaust. On the left side of the junction top face 348, there are three service outlet ports 351 for the " step climb " operator communicating through the plunger down guide, and three inlet openings 353 " to the canister " communicating with the three corresponding outlet ports. the apertures defined in the rear face of the junction box, which communicate with the respective inlet support apertures 363 defined in the front face 321 of the gossip switch assembly (FIG. 37), and three exhaust apertures 355 that communicate with the exhaust. The flow in each vertical group of holes is controlled by a separate regulator and valve (not shown for clarity) that will connect the duct "to the canister" either to operate the prop climb or to the exhaust. Junction box also splits ··

24 lubrication lines into three lines which are connected to the three lubrication inlet holes 313 (FIG. 37) on the front face of the plunger.

Referring to Fig. 37, it will be appreciated that the front face of the plunger also includes a plurality of additional inlet ports 365 for additional fluid functions such as mouth ring cooling, takeout pliers closing, air cooling, mouth ring opening / closing etc., which they are connected to the corresponding pipes in the junction box. These ducts can lead to outlets in the top surface of the junction box (not shown) that are connected to respective outlet ports of the corresponding number of individual regulators and valves (not shown for clarity) that distribute air from the plunger service line and regulate the required pressures.

The top surface 315 of the mouthpiece plate has three sets of outlet apertures, each having a plunger outlet outlet opening 366, a plunger outlet outlet opening 386, a pre-blow / vacuum outlet opening 370, a support outlet outlet opening 372, and a lubricating outlet opening 374. These outlet openings are universal (permanent), which means that the number of exit hole sets corresponds to the maximum number of molten glass batches that are processed in a section per cycle.

To create a specific configuration of the plunger (for one, two or three batches of molten glass) and to define the spacing of the plungers at a certain distance from one another (for example 5.5 ", ie 14 cm or 6", or 15.24 cm) in the case of a plurality of plungers, the transition plate 376 (FIG. 38) is attached to the upper surface 315 of the universal plunger guide plate by means of suitable screws 377. The transition plate has a plunger exit outlet hole 380, a plunger drop exit outlet hole 384, outlet. pre-pressure / vacuum port 384, support pitch 386, and lubrication service outlet port 388 in upper surface 390 for inlet of the downwardly projecting connection lugs 65 on the canisters (O-ring 71 forms a seal between the downwardly projecting lug and the respective inlet port - any movement of the mouthpiece canister either in the respective opening of the mounting plate or as part of the mounting plate will not cause the canisters to tilt because the necessary stability is ensured by O-ring seals in the inlet openings in the transition plate) and the mouthpiece exhaust 392 is shaped so that the respective mouthpiece exhaust tube 73 of the mouthpiece canister can enter. . The orifice exhaust ports communicate with the discharge port 378.

Changing one section configuration to another, e.g., changing from the described molten glass batch manufacturing process to a two molten glass batch manufacturing process, is accomplished by removing said three-molten glass transition plate and then replacing the transition plate for the molten glass batch. two batches of molten glass (Fig. 38A) which sealed one of the three sets of orifice outlet apertures on the top of the plunger, making the connection to the third set of orifices (the mouthpiece mechanism control will be modified to control only valve operation) etc. that are associated with two sets of holes in the transition plate.

In order to manufacture bottles having substantial height differences, it is possible to raise the oral circles / canisters by approximately 70 mm. The original transition plate having a height H1 and a mounting plate having a thickness D1 may be replaced by a transition plate and a mounting plate so as to increase their height up to 70 mm (H2 - Fig. 38 and D2 - Fig. 39 as appropriate) and oral circular the holder may be replaced by an alternative arm whose mounting bracket 113A raises the oral ring holder 112 from position P1 (FIG. 25) to position P2 (FIG. 39). A fixed stop 111 defining the position of the mounting brackets is shown in Fig. 40.

It can be seen in Figures 41 to 43 that a machine with a given pair of oral ring holders can utilize molds having a wide range of heights to produce bottles having different heights. While the front mold halves 17A, 17B, 17C, 17D (Figs. 41-43) and the spacer may have different shapes, the interconnection of the front mold halves and the spacer is defined to provide a fixed .31 "vertical dimension between the inverting center 434 and the upper the oral ring groove surface 438 436 of the front mold half (upper surface of the oral ring). In the case of the oral ring holder located in P1 (FIG. 25), this dimension could be, for example, 100 mm, while this dimension could be, for example, 30 mm if the oral ring is in P2 (FIG. 40). Each half of the front mold has a downwardly overhanging, circularly guided hook-shaped edge 440 near the lower surface, which may have a plurality of circular portions or sections and which enters a corresponding upwardly directed, circularly-guided hook-shaped edge 442 on the outer wall of the spacer. which vertically delimits the position of the half molds of the front molds (the front mold is vertically positioned in the horizontal plane of the connection of the downwardly overhanging edge of the front mold and the upwardly directed edge of the intermediate support of the front mold support). The half of the front mold may be of a size sufficient to provide a stabilizing button 442 in

-25 ·· frfr fr · · ·

Frfr frfrfr could extend vertically above the lower edge which cooperates with the upper edge 440 of the mold half to stabilize the mold during its movement (as shown, the stabilizing button 442 does not support the weight of the mold half). Since the mold halves are carried near the orifice at the location where the edge of the mold is supported by the edge on the mold support, substantially the entire thermal expansion effect will manifest upward from that location, and any downward thermal expansion effect will be insignificant (without the need for any adjustment of the orifice mechanism or ring that is usually required in prior art structures in which the front molds are carried near the tops of the molds). In addition, using conventional molds 380 (FIG. 4), which are hinged on top of a downwardly overhanging, circularly guided edge 382 having a plurality of sections supported by a corresponding upwardly directed, circularly guided edge of the intermediate mold support (not shown), which may also have a certain number of sections (located near the oral circular groove), the expansion of the mold halves by the effect of heat also manifests away from the mouth of the bottle (threaded portion) so that it is consistent at both stations.

It may be recalled that in the prior art it has often been required to purchase a new IS machine or rebuild an existing machine in connection with the rebuilding of one configuration (for one, two, three batches of molten glass) with some center distance to the same or different configuration with a different center distance. The main cause is the complicated mold opening and closing connections that define the different geometrical arrangements. The invented IS machine is a machine with a universal center distance. The original configuration / center distance can be changed to a different configuration / center distance required by manufacturing circumstances by simply replacing certain parts that will provide the desired configuration / center distance; that is, by replacing the mold carrier assembly of the mold opening and closing mechanism, the mounting plate, the transition plate, and possibly the mouthpiece canisters of the mouthpiece mechanism, the parameters of the mouth ring holders and mold cooling mechanism (in the case of the end station) and as usual, the machine configuration would be changed.

The takeout mechanism shown in Figs. 45 to 47 is mounted on the top surface 94 of the top frame section wall 134 and has a take-off clamp head 450 that can releasably grip the bottle (s) at the end station and which is supported on the. · Fl · fl · fl · fl · fl ·
