Description

Mechanism for opening and closing molds in IS machine

Technical field

The present invention relates to IS (individual sectional) machines which convert molten glass batches into bottles in a two-step manufacturing process, and more particularly to mechanisms for opening and closing molds in 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 into flasks having a threaded hole (mouth of the bottle) 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 the final molds of the aforementioned '159 patent are supported on inserts displaced by opposite carriers that are rotatable about a common axis of rotation in front of the molds.

-2 (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 the motors (liquid-actuated cylinders or rotary output motors) are located below the molds and each motor is connected to an associated pair of mold carriers by means of 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 shapes of the molds, 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-molding 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. There is nothing in these mold opening and closing mechanisms to block the molds at the necessary mold closing positions during flask formation, as a result of which the mold halves can be pushed apart and cause a 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).

An embodiment of an IS machine described in U.S. Patent No. 4,070,174 is called an 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, is called the ITF machine and is described in U.S. Patent No. 4,443,241. This machine, which has three ·· ··

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.

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 push-off mechanism (not shown) subsequently moves the made-up bottles • ·

-7 from a shutdown 14 to a conveyor 15 which leads them further 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 HA having a top wall 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 mold holding mechanisms of the front mold stations are the same, but the mold holding mechanism of one station may differ in size from the mold holding mechanism of another station as a result of differences in the manufacturing process 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 of the 17 molds (front or end 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 a right-hand thread and a lower-left-hand thread, via a fastener 68. The housing 90 carries a lead screw 70.

Fr fr frfr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr · ··· · ♦ ··

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 that 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 outwardly to form a more perfect base for the cabinet) with suitable screws 95, opposite side walls 96 that include stiffening ribs 97, and a removable top 98. The lead screw is attached to a linear transmission rotary positioner comprising nut means having a left-hand threaded lower nut 72 and a right-hand threaded upper nut 74 and which are disposed 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 beer pair of lift members 76 is connected at one end to the upper nut 74, the other pair of lift members 78 is connected at one end to the lower nut 72 and the yoke 82 has a horizontal bore 91 supporting a transverse, 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, rotating the lead screw 70 in one direction will subsequently slide 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 screw and a mechanism for holding the molds 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 • 4 · ··

9, and horizontally because the axis of the vertical shaft 27 extends through the center of the carrier body 30 (and the intermediate elements 24) 1. 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 pivotally carries 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 linear transmission rotary positioner will be transmitted directly to the intermediate elements 24 - the carrier 30 is not in the gripping path of the load.

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 88 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 requirement of being strong enough to bring the nut abutment surfaces 84 into contact with the back wall abutment surface 86 as necessary as the mold holding mechanisms are pushed until the clamping contact of the opposite mold halves when the desired load is applied to them. 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. In order to ensure lubrication of the bearing 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 ensure greater strength, it can

The lead screw housing 90 (FIG. 6) should be doubled so as to support additional lead screws to 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. 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 for accommodating said flange and having a flat, horizontal, supporting surface 36 for traveling on a flat, a horizontal, abutment surface (track) 41 delimited on a square shaft 40 that is a square and which is part of a bracket 42 attached to the sectional 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 abraded 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 the a corresponding cylindrical support surface of the shaft 50.

The reversing and holding mechanism 110 (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 demonstrated closed position by the operation of the respective horizontally positioned pneumatic cylinders 114. These mechanisms include:

• · • ····

The orifice ring holders, in turn, carry the mouth ring halves 115 which close the bottom of the molds when the mold halves are clamped and which, when the mouth rings are closed, determine the shape of the mouths (threads) of the 116 flasks and finally the bottles. After forming said orifice shape, the orifice holders 120 rotate 180 ° as a result of operation of the inverting and holding mechanism of the orifices 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 holding 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.

It can be seen in FIG. 8 that the annular shaft 50 of the opening and closing mechanism of the molds, which is located near the inverting and holding mechanism of the orifices, is mounted at each end in opposite, inverting brackets 122. The rotating shaft of the opening mechanism and the closing of the final molds takes the form of a two-part circular shaft 50A, 50B. These shafts are mounted coaxially and each is housed in an inverting bracket 122 at one end and a vertical worm block 118 at the other end. Regardless of whether it is a front mold station or end mold station, the square shaft 40 allows the the carrier expanded further away from the turning axis (center of the section) due to the 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 of these mounting blocks has a pair of vertically spaced bearings 170 spaced apart by the circular shafts 50C 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 the expansion of the drive block due to the temperature increase is not as great as the thermal expansion of the carrier 30 , a buffer mechanism is built into the carrier so that regardless of whether it is a front mold station or a rear mold station, the carrier will be • 0 »• 00

-12 stretch as the temperature increases in the same direction further from the center (turning axis) of the section. 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 prior art IS machines, the effect of thermal expansion for the side of the front mold station was directed toward the invert and hold mechanism of the circular orifices, while for the side of the final mold station it was manifested away from the invert and hold mechanism of the circular orifices. 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 coincides with the top of the carrier 30 and which 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. A flap 58 control actuator, 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 kiytu. The λ- ^{7 in the} retracted position is the top edge of the cover near the hinge 60. When the carrier is pulled away, the top of the cover (and the flap) will move to a slightly sloping position and the flap and top will move appropriately to accommodate displacement.

13 Based on the operation of the mold opening and closing mechanisms located above the top wall of the sectional frame and the operation of the transmissions driven by electronic motors mounted so as to be directed downwardly from the top wall of the sectional frame, the floor section is opened sectional frame, which is filled in a known manner with these engines (pneumatic cylinders) and transmissions (couplings). The sectional frames 11A of the machine (there may be 6, 8, 10, etc.) 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 openings 136 in the bed sides 132 separated by side wall ribs 137 for sliding entry of a number (eight in the preferred embodiment) of seamless, square ducts 138 conducting fluids that extend through the entire width of the machine. These pipelines 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 supply ducts 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.

The pipes 38 which extend from one end of the machine to the other and which are connected to the respective sources are releasably attached to each two sectional beds by means of a clamping structure (Fig. 14) comprising an I-beam 147 carrying all the pipes, and a clamping device 148 at the front and rear of the bed, the clamping device being attached between the I-beam and the top wall of the bed. Each clamping device has an operating screw 149 having a tightening head 151 and which secures the conduit 138 through the respective apertures 153 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 can subsequently be slidly replaced and replaced by several other 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 the motors (servomotors). As can be seen, the motors are electronically coupled to each other. Motor / encoder number 1 (control) M1 / 154 monitors the request signal from the motion controller position sequence controller 150. The feedback motion control processor 152, which receives a digital feedback signal from the encoder portion of motor / encoder number 1, transmits the 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 a 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 sends a signal to the second amplifier 162, which controls the operation of motor / encoder number 2 (slave) 168.

Separation of the mold halves with complete withdrawal of the mold carriers (each in the initial position) can be predetermined and the ideal center point of the mold movement is half the 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, a speed test of each motor is performed and, if the speed of one motor (VM1) and the speed of the other motor (VM2) equals zero, the next step in the feed program starts by provides a velocity profile that will control the operation of the motors at very low speeds (Vs) - (this may be any command that will activate the motors). When the actual speed of each engine 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 (-I - / - .. X "from the ideal center point). The encoder associated with each motor provides data to determine the actual end position. If the mold carriers are in an acceptable position, a third feeding step can be performed.

-15the program in which the operation of each engine generates a selected torque over a specified period of time ("TI"). which can be set up 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 controlled at a low speed - VS, with a minus sign indicating rotation in reverse (which can be set - the arrow represents the computer input) for a limited time section 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 section in 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 an ideal center position (one half of the total distance plus the selected distance that would result in be gripping opposite mold holders with subsequent stopping). The fact that both mold holders have stopped is verified (the error signal can be monitored) and the actual position of each mold holder is determined and compared to the position of the ideal midpoint. 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 a sectional frame 11A. A carrier arm 182 that carries the three bolt heads 184 (the bolt-head mechanism is shown schematically because there is a large variety of bolt heads). · · · «

-16 specific design solutions) is attached to the vertical control rod 186. This overtightening rod will lift and rotate during the time it is in the highest elevation section so that the breech heads can move between the raised, retracted position and the lower retracted position. the position in which they will be on top of the front molds. 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 a 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. It can be seen in Fig. 17 that the cam sleeve has a pedestal 208 which is secured by screws 209 to the top wall 134 of the section frame 11A on the axles of the breech heads coincident with the axes of the closed front molds. Upon actuation of the cam, the lock heads first lift partially above the front molds and then, as they move upward over the remainder of their transfer path, these lock heads move further away from the centers of the front molds so that the invert and hold mechanism of the circular orifices can displace flasks to final forms. The bolt head mechanism may be located at the front of the sectional frame at each corner and, unlike the hitherto known bolt head mechanism, the fully raised and retracted bolt head arm may generally be within the section space as shown in Fig. 17 and may not extend into the space of 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 a circular sealing surface 265 that can slide in the bore 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 parts when the breech head is separated from the front mold.

When the breech head is moved down to the front mold as shown in FIG. 20, the actuator (FIG. 23) moves the flange 270 downward until the flange lids are at a first distance D1 from the top surface 272 of the front mold to which the cylindrical head will be lowered relative to the cup-shaped portion to define the necessary "X" clearance 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 shape to the vertical distance "y"). This generates the required compression force between the piston member and the front mold creating 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 annular surface 281 of the cylindrical head comes into firm contact with the upper surface 272 of the blank mold and closes the blank mold. 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). then through the radial portions 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 the rod of the relief holes 282.

If it is desired to use a funnel mechanism 210, then this device may be mounted in another front corner. It can be seen in Fig. 24 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.

8-10. The end of each orifice holder adjacent to the worm gear housing 120 is in the form of a groove fastening bracket 113 having its bayonet end 109 slidably mounted on a support bracket 117 that is attached to the inverting The cylindrical outer end 119 of the cylinder 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 portion 125 in the side bracket and is 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 On the console 131, which is attached to the worm block 118, is another pair of proximity switches 124A (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 signal the proximity switch to move 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 by the orifice holder at the top of the plunger mechanism (180 ° inverted starting position), to a second position (180 ° back from the beer position) in which the oral book halves hold the flasks at the final blow station (0 ° inverting end position). In this context, the terms " mouth ring open " and " mouth ring closed " will be used to describe the position of the ring mouthpiece / bracket / cylinder, and the actuator functions will be described with reference to one ring mouthpiece . Since the servomotor 108 has an encoder that generates positional feedback, the angular position of the book-mouth 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 / starting turning position (180 °) to the end turning position (0 °). If the mouth ring 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 in 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 sensor 124A on the worm block to the open position detected by sensor 124 on the side console. The time between the two signals is measured as "AT" and compared with the ideal time difference (original time difference) and the time ("T") deviation, which is the difference between the actual and ideal time interval is sent to the control device controlling the cylinder operation. to control the oral circle. If the “T” deviation 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 indicating the need for maintenance intervention.

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 operated to provide the necessary angular displacement. At the selected rotation angle (Q1 ideal), the control device will control the operation of the orifice ring to move the orifice from the open position to the closed position. Such action will be determined by certain limits that stipulate that Q1 must be greater than X ° and that the movement of the oral ring must be completed after reaching Y °. The values of X, Y and Q1 are independently adjustable. The control device determines the actual angle (Q1 actual) when the mouth ring detection sensor 124 is open, and determines 01 deviation # 1 by subtracting the Q1 actual from Q1 ideal. This deviation is sent to a control device for correcting the position in which the orifice ring is in operation. If this deviation is excessive or even incorrect, a warning signal is sent.

In addition, the control device monitors the situation where the oral circle assumes a closed position defining an angle of 02 actual and the sensor detects a " 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 time required for displacement increases, and such a delay may cause the moving structure (the structure of the oral ring) to strike the front molds that would be beyond its reach in no circumstances.

-20the device determines the second Θ1 deviation (Θ2 ideal minus Θ2 actual) and makes 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 comprises, 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 so as to connect the plunger canister to the necessary. operating services (chilling, gas evacuation, chute, chute, vacuum / vacuum (in blow molding machines) or truss cooling (in press-blow machines), lubrication, support climb). 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 plunger mechanism will be described 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 cooling the punch in the press-blowing machine. Mounted at the top of each upper cylinder is a mounting plate or flange 77 and 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 fastened to the upper surface of a mounting block or plate 85 having apertures 87 (FIG. 33) through which upper / lower rollers can walk through suitable fasteners and this mounting block is secured to the upper surface 94 of the section frame 11 by means of The upper surface of the sectional frame has a large opening (not shown) into which the plunger cartridges 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 properly machined to be parallel, and the height of the mounting block corresponds to the location of said tool. «9 · · · · · ···········

-21 equipment 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 orifice canisters, the axes of the orifice canisters will assume the necessary position upon insertion. By placing diamond and circular dowels (not shown) on the top wall of the section frame and defining suitable holes in the lower surface of the mounting plate, mounting of the mounting plate is automatically performed. Since the top of the canister is attached to the top wall of the section frame, the effect of thermal expansion will not significantly affect the position of said tooling.

The four beer pipelines led under the front mold side of the section (Fig. 34) are pneumatic operators for lowering the plunger (piping 300 - approximately 3.1 bar), pre-flow (piping 302 - approximately 2 to 3 bar), vacuum (piping 404) and mouthpiece pitch (pipe 306 approximately 1.5 to 2.5 bar). These operators are connected via openings in the top walls of the pipeline to the vertical inlets 308 in the lower part 310 of the plunger distributor 312 through the corresponding passages 314 in the connecting plate 316. These four pneumatic operators are led through the plunger distributor into outlet ports 320 in the front face of the plunger distributor. pedestals. The fifth fluid conduit 301 is routed below the bottom wall of the front 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 foamed opening 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 service 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).

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 openings 334 for operating the plunger stroke function associated with a single plunger inlet port, three exhaust ports 336 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 junction box e (Fig. 37). The flow within each vertically arranged group of orifices on this left-hand side can be controlled by a pressure adjusting device such as a regulator / valve and collecting tank (not shown for clarity) that will be connected either to the "canister" line or lockout.

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.

The junction box also divides the lubrication lines into three lines that 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 manifold 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.

That the number of exit aperture 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 orifices (for one, two or three batches of molten glass) and to define the spacing of the orifices at a certain distance from each other (e.g. 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 plate by means of suitable screws 377. The transition plate has for each canister outlet opening 380 a plunger outlet, outlet opening 384 plunger drop, outlet pre-vacuum / vacuum port 384, support pitch 386, and lubrication service outlet port 388 in the 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) the canister either in the respective opening 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 port 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, i.e., changing from the described process of processing three batches of molten glass to a manufacturing process of processing two batches of molten glass, is accomplished by removing said three-molten glass transition plate and then replacing the transition plate for two batches of molten glass (Fig. 38A) which tightly closes one of the three sets of mouthpiece outlet openings on the top surface of the mouthpiece base, making the connection to the third set of holes (control of the mouthpiece mechanism 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 HJ 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 - Figures 38 and 1) 2 - Fig. 39, respectively, and the oral ring holder may be replaced by an alternate arm whose mounting bracket 113A raises the oral ring holder 112 from the P1 position of the position P1. · · · · · · · · · · · · · · · · · ···· · · · · · · · · ·

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 create a fixed vertical dimension "H" between the center 434 of invert and 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 PI (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 number 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 defines the position of the half molds of the front molds (the front mold is vertically positioned in a horizontal plane joining the downwardly overhanging edge of the front mold and the upwardly directed edge of the intermediate mold support of the front mold). The mold half may be of a size sufficient to allow the stabilizing button 442 to extend vertically above the lower edge which cooperates with the upper mold edge 440 to stabilize the mold during its movement (as shown, the stabilizing button 442 does not carry the stabilizing button 442). weight of half mold). Because the mold halves are supported near the oral circular groove at the edge of the mold being supported by the edge on the mold support, substantially the entire thermal expansion effect will be upward from that location, and any downward thermal expansion effect will be insignificant (without the need for any adjusting of the orifice mechanism or ring that is usually required in the 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), with the expansion of halves »· • ·

The effect of heat also manifests itself 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 was often required to purchase a new IS machine or to rebuild an existing machine in connection with rebuilding 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 perhaps the canister junction canisters, the parameters of the oral ring holders and mold cooling mechanism (in the case of the final station) and as usual, the machine configuration would be changed.
