2. Description of the Prior Art S. As a machine patent, 19
U.S. Pat. No. 1,843,159, issued Feb. 2, 32,
And U.S. Pat. No. 1,9, issued May 23, 1933.
No. 11,119. Today, more than 4000 I.D. S. Machines are used around the world, producing over billions of bottles daily throughout the year. I. S. (Individual section)
The machine has a plurality of identical sections (a section frame with a number of section mechanisms mounted within and on it), each of which sections
A blanking station for receiving one or more molten glass gobs and transforming the gobs into parisons having threaded openings at the bottom; and an upright stand for receiving the parisons and having the parisons finished at the top. And a blowing station for forming bottles. A reversing and neck ring holder mechanism having a pair of opposing arms rotatable about a reversing axis transports the parison from the blank station to the blowing station, and during the process, the finishing portion from the direction in which the finishing portion faces downward. Flip the parison in the direction that is facing upwards. The bottle formed at the blowing station is discharged from the section by the unloading mechanism.

[0003] The blanking station has an opposing pair of blanking dies, and the blowing station has an opposing pair of blowing dies. These molds are movable between an open (separated) position and a closed position. The opposite pair of neck ring dies supported by the reversal and neck ring holder mechanism (supported near the top) are:
The finished part of the bottle is defined and holds the formed parison as it is conveyed from the blanking station to the blowing station.

[0004] The blank and blow molds of the aforementioned US Patent No. 1,843,159 are supported by opposing carriers that are rotatable about a common pivot point at the front of the mold. (The front-to-back movement is defined by the parison moving from the blank mold to the blow mold). Both the blank mold support mechanism and the blow mold support mechanism are operated by linear motors (liquid operated motors). The linear motor of the blank mold support mechanism is attached to the front of the pivot point of the blank mold support mechanism, extends horizontally outward from the front of the section frame, and a pair of links are provided for the motor of the blank side. The output is connected to the support mechanism of the blank mold. The linear motor of the blow mold support mechanism is mounted vertically on the side of the pivot point (the mechanisms in both sections are commonly referred to as mold opening and closing mechanisms). The first I. S. The machine has motors (hydraulic cylinders, or rotary output motors) located below the molds, each motor extending vertically from the bottom of the section in front of or behind the pair of mold support mechanisms. (See U.S. Pat. Nos. 4,362,544 and 4,42) via associated transmissions.
7,431). The drive linkage applies a torsional force through the carrier, which is not desirable. Further, the drive connection mechanism must be designed to fit a specific mold, but when changing from one gob form to another gob form, the entire connection mechanism and the mold support mechanism are also changed. It is common to change. In such machines, the baffle and funnel mechanisms must be located on the side of the section adjacent to the middle section, which makes maintenance of such mechanisms difficult and requires that adjacent sections be deactivated. Often not.

[0005]

The blank mold is open at the top and the track feeds the gob vertically downwards by gravity to a position above the open mold. If the bottle to be formed is not of circular cross-section (for example, of square cross-section), the funnel part having a square passage (funnel part) is moved to a position above the open top of the blank mold and the gob is molded. Inward, the shape can be slightly changed during the process. When the gob is in the blank mold, the baffle plate (warping plate) of the baffle mechanism is moved down to the funnel portion, and pressurized air is supplied to the blank mold through a number of exposed holes, and the gob is moved to the blank mold. Within the "stable" (settle). Next, the funnel portion (funnel portion) and the baffle plate (bent plate) are removed, and the baffle plate (bent plate) is placed again on the top of the opened blank mold. At this time, the settle blow holes are closed. Next, in order to blow the gob into the mold, directional blowing air is introduced into the mold (blow-blow machine), or the plunger is advanced to push the gob into the mold (press-blow). machine). The air taken in between the outer surface of the gob and the inner surface of the blank mold is discharged from a suitable relief passage formed on the bottom surface of the baffle plate (bent plate). Once the parison is formed, the baffle plate (warp plate) is removed, the blank mold is opened, and the parison is transported to the blank mold. If the gob does not need to be shaped, the funnel can be omitted and a baffle plate can be immediately placed on top of the blank mold to begin the resting process. In a conventional baffle plate of this type, a central piston projects from the bottom of the baffle plate to form a large central opening for air stabilization. When a countercurrent blow occurs, the upward movement of the gob engages the piston and pushes the piston upward to its original position, at which point the bottom of the piston is baffled.
And there is a small annular groove between the piston and the bottom surface of the base. Air can escape from the blank mold through the annular groove through the baffle plate (deflection plate) constantly. The bottle thus formed is seen to have a circular ridge at the bottom of the bottle, which is undesirable.

Accordingly, one object of the present invention is to form a baffle mechanism and a funnel mechanism that are easier to access and limit their operation so that less space is required.

[0007] Other objects and advantages of the present invention will become apparent from the following description of the present specification and the accompanying drawings, which illustrate a presently preferred embodiment embodying the principles of the present invention. .

DETAILED DESCRIPTION OF THE INVENTION S. The machine 10 has a plurality (typically 6, 8, 10 or 12) of sections 11. Generally, the section is a box-shaped frame or section box 11A that houses or supports the section mechanism.
(FIG. 2). Each of the sections receives a separate molten glass gob and a blank station having a first mold opening and closing mechanism 12 that supports a blank mold that forms the gob into a parison, and receives the parison and forms the parison into a bottle. And a blowing station having a second mold opening / closing mechanism 13 for supporting the blowing mold. 1, 2, 3, or 4 at each station
One gob, a single gob, a double gob, a triple gob (depicted in the illustration), depending on the number of gobs processed simultaneously in each section in a single cycle. Embodiment) or a quadruple gob machine. The formed bottle is removed from the blowing station by a removal mechanism (FIG. 43) and conveyed to a mouth plate 14 and then conveyed by a conveyor 15 by a pusher mechanism (not shown), which removes the bottle from the machine. Take out. The front side (or section) of the machine is the end remote from the conveyor, the rear side of the machine is the end adjacent to the conveyor, and the side of the machine or section extends perpendicular to the conveyor. . The movement from side to side is in a direction parallel to the conveyor.

FIG. 2 shows a portion of a section 11 of a triple gob machine formed in accordance with the teachings of the present invention, schematically illustrating any of the forming stations. Section 11 includes a top wall 13 having a top surface 94 and side walls 132.
Section frame 1 in the form of a substantially box with 4
1A. Each of the mold opening and closing mechanisms includes a pair of opposed mold supporting mechanisms 16. Each of the mold support mechanisms is connected to and actuated by drive assembly means, the drive assembly means comprising a rotary-linear motion transmission (conversion) mechanism (rotary-linear motion transmission).
The transmission is mounted on the top of the section frame 11A and is driven by a driving device. The drive 19 moves the associated mold support mechanism 16 between a retracted and separated position and an advanced position.
Has a rotational output that displaces linearly toward the side direction,
When in this forward position, the mold halves supported by the opposed pair of mold support mechanisms are forcibly engaged. The mold mechanism for the blank station is the same, and the mold support mechanism for the blow station is the same, but the mold support mechanism in one station is a process step well known to those skilled in the art. As a result, the dimension can be different from the mold supporting mechanism in another station. Since the machine shown is a triple gob machine, each of the blank or blow station mold support mechanisms supports three mold halves (blank or blow mold) 17.

Referring next to FIGS. 3, 4 and 5, the portion interconnecting the mold support mechanism to its driver and the means for displacing the mold support mechanism between the advanced and retracted positions. Will be described. FIGS. 4 and 5 show only a mold support mechanism that supports a mechanism associated with a single section. On the other hand, FIG. 6 illustrates an alternative housing that supports two mold support mechanisms when two sections are adjacent and supports only one mold support mechanism when there is no adjacent section. ing. The drive 19 has a servomotor 66 (gearbox and / or direction change device) having a rotation output in the form of a main shaft 67 (FIG. 4), the main shaft 67 comprising an upper right-hand thread part and a left-hand thread. Lead screw 70 having a portion (eg,
Ball or acme screw) via a coupling 68. A housing 90 supports the lead screw 70. The lead screw is supported at both ends vertically in a housing 90 by a suitable single radial or double ball bearing drive 99.
The housing includes a base 93 secured to the upper surfaces 94A, 94B (FIG. 6) of two adjacent section frames by suitable screws 95 (the top wall of the section extends outwardly when there is no adjacent section). And supporting the housing), opposed side walls 96 with reinforcing ribs 97, and a removable top portion 98. The lead screw comprises a lower left screw nut 72 received by the lead screw and an upper right screw nut 7.
4 connected to a rotary-linear motion transmission mechanism (rotary-linear motion transmission). The rotation-linear motion transmission (conversion) mechanism uses a nut 7
2 and 74, further comprising means for interconnecting the mold support mechanism with the mold support mechanism, the mold support mechanism comprising an upper nut
4, a second pair of jack links 78 connected at one end to the lower nut 72, and a horizontal hole 9 for supporting a transverse horizontal rotation shaft 80.
The other end of the jack links 76, 78 is rotatably connected to the horizontal rotating shaft 80 (a sleeve or flange bush is used to extend the life of the link). Is done). The yoke 82 has a vertical hole 92 for rotatably receiving the vertical rotation shaft 27 of the mold supporting mechanism. Therefore, when the lead screw 70 is rotated in one direction, the mold supporting mechanism moves forward toward the opposed mold supporting mechanism, and when rotated in the opposite direction, it moves in the opposite direction. The jack leads 76, 78 provide a toggle coupling mechanism that is movable between an extended position and a retracted position, the coupling mechanism comprising:
It operates horizontally between the housing 90 and the mold support mechanism.

Each of the mold support mechanisms includes a carrier 30,
Upper and lower inserts 24 for supporting the mold halves, the inserts extending through the vertical holes in the carrier 30, the insert 24 and the yoke 82.
7 supported on the carrier 30. Yoke 82
Is received in the space 101 of the carrier 30. As is evident from the drawing, the lead screw is in the vertical direction, adjacent to the mold supporting mechanism, and interconnects the rotation output side (lead screw) of the servomotor and the mold supporting mechanism, The linear motion transmission mechanism (rotary-linear motion transmission) is mounted on the top wall 1 of the section;
It is arranged in a compact form between the lead screw and the mold support mechanism at the top of 34. The rotary-to-linear motion transmission is located just above the top of the section frame and applies a load to the mold support via the yoke (vertically and horizontally) at approximately the center of the mold support. (Vertically, the axis of the horizontal axis 80 is located midway between the upper insert 24 and the lower insert 24, and in the horizontal direction, the axis of the vertical axis 27 is the mass of the carrier 30 (and insert 24). Located in the center). The load transmitted directly from the vertical axis 27 to the upper and lower inserts 24 lies in a plane extending perpendicular to the engagement surface of the mold and intersects the center of the mold (center of the central mold). I.e., there is an equal number of molds in the middle between the central molds). The direction of this load is
Perpendicular to the engagement surface between the opposing mold halves (clamping surfaces), the vertical pivot axis 27 rotatably receives the insert 24 and the yoke 82, and the yoke is Since the horizontal rotation shaft 80 connected to the toggle connection mechanism is further rotatably supported, no torsional force is applied to the insert 24 when a mold clamping load is applied. Therefore, rotation-
The force applied by the linear motion transmission is transmitted directly to the insert 24 and the carrier 30 is not located in the force path of the clamping load.

Each of the nuts 72, 74 has a flat rear bearing surface 84 associated with a flat, elongated, vertical machined bearing surface 86 defined in a rear wall 88 of the transmission housing (cast) 90. ing. As the mold support mechanism retracts, the selected gap separates the rear bearing surfaces of the nuts 72, 74 from the vertical bearing surface 86 defined in the rear wall. The lead screw is selected to have the following rigidity. That is, the mold supporting mechanism is moved forward so that the supported mold half engages with the opposing mold half in a mold-clamping manner, and when a desired load is applied during that time, the lead The screw 70 is sufficiently flexed to be rigid enough to engage the bearing surface 84 of the nut with the bearing surface 86 of the wall. The lead screw housing (transmission housing) 90 is
It has enough rigidity to: That is, prior to applying this load or fastening in place, the removable top portion 98 is adjusted to provide rigidity to set the desired clearance between the nut bearing surface and the wall bearing surface. To have. Thus, the mold halves, the mold support mechanism, the opposed transmission and the housing 90 define a truss (consisting of a triangular structure) supported above the top surface of the section frame and during the molding process. Prevents the mold halves from displacing vertically due to vertical loads (and therefore
The truss isolates the support shaft from the underlying load) or prevents the mold halves from separating laterally (horizontally) due to the vertical load applied during the molding process. Bearing surfaces 84, 8
To lubricate 6, an oil groove 100 may be defined in rear wall surface 86 and lubricating oil may be supplied to this groove via a suitable passage extending through lead screw housing 90. The machined surface can be impregnated with a solid lubricant to minimize friction. Lead screw housing 90 for greater strength
(FIG. 6) may be duplicated so that the housing can support the lead screw from an adjacent section. This adjacent section is connected to a rotary-linear motion transmission.

Each of the inserts 24 (FIG. 7) is pivotable about a vertical pivot axis 27 and supports a first half of a mold half and a second portion 28. The second portion supports the other two mold halves and in a position ensuring that equal forces are applied to each of the molds. Through a pivot pin 29. The pivot 27 passes through the first insert 26 of the upper insert 24, the upper wall 30A of the carrier 30, the transmission yoke 82, the lower wall 30B of the carrier 30, and finally the lower insert 24.
Extend slidably downward through the first portion 26 of the first member.
The upper insert 24 (a pair of pins 31 extending downward through the carrier 30 and the lower insert 24 is selected relative to the insert portions so as to limit the desired movement of the first and second insert portions 26, 28). With a gap.

As described below, the mold supporting mechanism is
It is slidably mounted so as to be movable on two parallel shafts 40,50. The carrier 30 extending in a direction parallel to the mold clamping surface has an external mounting flange 32 (inverted / neck ring holder mechanism—away from FIG. 8) at one end. The mounting flange is a block 3 having a suitable notch 38 for receiving the flange.
5 is secured by a suitable fastener 34. The block also has a flat horizontal bearing surface 36 that rides on a flat horizontal bearing surface (passage) 41 defined on the shaft 40. The shaft 40 is square and a part of the bracket 42. Bracket 42 is secured to the section frame adjacent one end (bracket 42 may optionally be formed as part of a housing for other mechanisms). A wiper (not shown) can supply lubricant to the block to keep the passage surface clean and lubricate the bearing surfaces. The inner end of the carrier 30 (closer to the inversion and neck ring holder mechanism) is secured to an "L" shaped block 46 by a suitable fastener 34, the L shaped block being integral with a bearing block 48; The L-shaped block has a cylindrical bearing surface that slides on the cylindrical bearing surface of the shaft 50.

The reversing and neck ring holder mechanism 110 (FIG. 8) is mounted on the top of the section box between the blanking station and the blowing station. The mechanism includes a pair of opposed neck ring holders 112 that can be displaced from a disengaged position to a closed position shown by a suitable pneumatic cylinder 114 oriented horizontally. These neck ring holders support an opposing pair of neck ring halves 115 that close the bottom of the blank mold when the mold halves are closed, the neck ring halves holding the neck ring. When closed, the parison finish (thread) 116 is defined, ultimately forming the bottle. Once the finished portion has been formed, the servomotor 108 is actuated to rotate the drive shaft in the form of a worm (not shown) supported by the worm housing 118, thereby providing a neck ring with a reversal / neck ring holder mechanism. 180 degrees holder 112
Rotate. The worm includes a worm housing 118
, Which rotates a worm gear supported within a suitable worm gear housing 120. The cylinder 114 of the reversing and neck ring holder mechanism is suitably supported between opposed and separate vertical supports or brackets 122 and the worm gear housing. A vertical worm housing 118 and a reversing bracket 122 are secured to the top of the section frame.

As is apparent from FIG. 8, the round shaft 50 for the mold opening / closing mechanism on the blank side arranged at a position close to the reversing / neck ring holder mechanism is moved by one of the opposed reversing brackets 122. Is supported at one end. The round shaft for the opening / closing mechanism of the mold on the blowing side is a round shaft 50A, 50B composed of two parts. The shafts are mounted coaxially, each of which is supported by a reversing bracket 122 at one end and a vertical worm housing 118 at the other end. The square axis 40 allows the carrier to expand in the same direction away from the reversal axis (the central part of the section) with increasing temperature, whether at the blank station or at the blowing station. I do.

Alternatively, the two round shafts 50C may be mounted directly on the carrier 30, as shown in FIGS. The free ends of these shafts are slidably received by suitable bearings 170 (FIG. 10) located in suitable holes 171 of a pair of mounting blocks 172 designed integrally with the lead screw housing 90. Each of the mounting blocks has a pair of spaced bearings 170 that receive the round shaft 50C from the mold support mechanism in the adjacent section. Each pair of round axes associated with a particular section (upper section and lower section) has a horizontal yoke pivot 8
It is arranged vertically at equal distances above and below the 0 axis. The thermal expansion of the drive housing is not as great as the thermal expansion of the carrier 30, so that the carrier, whether at the blowing station or at the blanking station, centers in the section as the temperature increases (reversal axis). A correction mechanism that uniformly spreads in a direction away from the camera is incorporated in the carrier. As shown in FIG. 11, the screw 174 engages a key 176 on one side of the carrier 30 slidable horizontally in an elongated horizontal keyway 177 with an outer round shaft 50C on the opposite side of the carrier. And connect with each other. Holes 178, 179 in the round shaft and the screw receiving carrier have sufficient clearance for the key to slide horizontally (relatively) within the keyway, and the round shaft Allows it to remain parallel to the other circular axis over a range of ambient temperatures.

The embodiment shown in FIG. 8 and FIGS.
In both of the embodiments illustrated in FIG. 0, each of the carriers is supported on a round shaft located between the reversal axis and the center of the mold opening and closing mechanism. Further, each of the carriers is supported on the axis opposite to the center of the mold opening / closing mechanism on an axis capable of supporting expansion by temperature from the axis of the reversing / neck ring holder mechanism. This means that the temperature expansion of both the blowing station and the blanking station occurs in the same direction (away from the axis of the mechanism of the reversing and neck ring holder). This has not been realized conventionally. All conventional I.P. S.
In the machine, the expansion on the blank side occurs toward the reversal and neck ring holder mechanism, while the expansion on the blow side
It occurs in the direction away from the reversal / neck ring holder mechanism. In this regard, inflation at the blank and blowing stations always occurs in the same direction as at the neck ring holder, allowing the machine to achieve more alignment.

FIG. 12 shows one shielding structure of the lead screw housing. As shown, the carrier is completely retracted. The shield has an inclined front wall 52 that extends to the same extent as the top of the carrier 30. The front wall is connected by a hinge 53 to the rear top edge of the carrier. The shield also has side portions 54 integral with the top portion inclined along each edge 56 of the top portion. Each of the sides, when in this retracted position, has a vertical portion 57 covering the end of the carrier.
It has. A control portion of the shield, in the form of a flap 58 connected to the front edge of the top portion 98 at a hinge 60, is secured to the inclined front wall 52 of the shield and in opposed brackets 61 projecting inward. Accepted to. When in the retracted position, the top edge of the shield is adjacent to hinge 60. When the carrier is advanced, the inclination of the top portion of the shield (and the flap) becomes smaller, and the flap and the top portion move relatively so as to correspond to this displacement.

A transmission of the mold opening and closing mechanism is disposed above the top wall of the section frame, and is operated by an electric motor mounted to extend downward from the top wall of the section frame as shown. In this state, the bottom of the section frame filled with the motor (pneumatic cylinder) and the transmission (connection mechanism) is normally opened. A machine section frame 11A (which may be 6, 8, 10, etc.) is mounted on the base of the machine defined by a plurality of interconnected two-part floors 130 (FIG. 13). I have. Each of the two-part floors 130 has a side wall 132 and a top wall 134.
The two-part floor comprises passage means extending from one side of the floor to the opposite side, contiguous with a rectangular opening 136 in the side 132 of the floor, the passage means comprising: Separated by sidewall ribs 137 that slidably receive a plurality (eight in the preferred embodiment) of seamless rectangular fluid ducts 138 extending across the entire width of the machine. Air pressure, cooling air, process air, lubricant, process vacuum, and the like are supplied to these ducts as needed. The top wall 134 has an opening 140 for the blanking station and an opening 142 for the blowing station, which are connected to these fluid ducts 1.
Expose 38 in each of the section boxes. Section cables and wires extend below the fluid ducts in suitable conduits, creating a gap between the group of ducts and the wiring boat 145 defined in the top wall 134 of the floor so that they can be connected to individual mechanisms. It extends upward through it.

A duct 138 extending from one end of the machine to the other end and connected to a suitable source comprises a clamping structure (FIG. 14) having an "I" beam 147 located below all ducts; Toggle devices 14 at the front and rear of the floor connected between the "I" beam and the top wall of the floor
8 releasably clamps to each of the two section floors. Each of the toggle devices has a toggle actuation screw 149 having an engageable head 151 that can access the duct 138 through a suitable floor opening 153.
One. When the actuating screw is turned in one direction, the duct is pressed against the side wall ribs 137 and lifts the ribs upwardly to urge the ribs 143 into engagement. The rib projects downwardly from the top wall 134 at the base of the two sections. If one of these ducts is removed and, for example, it is necessary to replace the duct with two ducts, turning the engageable head of the toggle mechanism in the opposite direction releases the clamping mechanism of the duct, Ducts can be slidably removed and replaced with a large number of side-by-side ducts (ducts can be added or omitted to achieve the desired number of ducts).

Referring to FIGS. 15 and 17, each of the motors of the mold opening / closing mechanism is supplied in a usual manner, that is, a feedback signal is supplied to the operation control device, and the control device controls the motor (servo motor). It operates in a way that controls the servo amplifier to be activated. As shown, these motors are interlocked together electronically. Motor / encoder N
o. 1 (master) M1 / 154 is the operation control device 15
5 in accordance with the instruction signal from the instruction position sequencer 150.
Motor / encoder No. The signal from the position feedback processor 152 of the motion controller that receives the digital feedback signal from one of the encoder portions is provided to a summing circuit 156. The summing circuit outputs a digital signal to the instruction signal processor 158. One motor / encoder is provided to the amplifier 160 for operation. The instruction position sequencer of the operation control device receives a signal from the summing circuit 156, processes this signal into a request signal, and sends the signal to the second summing circuit 161.
66 from the motor / encoder No. 66. 2 (M2 / 168) to receive a digital feedback signal from the encoder and output a digital signal. This signal is converted by a command signal processor 159 of a second amplifier, which supplies the signal to a second amplifier 162, which converts the motor / encoder No. 2 (Dependent device) 168 is activated.

When the mold carriers are completely retracted (when each of the mold carriers is in the starting position), the degree to which the mold halves separate can be determined, with the middle in the mold operation. It is an ideal center point. In the first step of the supply program, the instruction position sequencer 150 uses the motor (M
1, M2) to set a displacement profile, the motors being electronically linked together to displace the dies cooperating with these motors to the ideal center position. To confirm that the displacement of both mold carriers was achieved, the speed of each motor was tested and one motor (M
If the speed of V1) and the speed of the other motor (MV2) are zero, the next step of the supply program is started and the command position sequencer generates a speed profile, which is The motor is driven at a very low speed (Vs). This can be any command to operate the motor. When the actual speed of each of the motors again goes to zero, the actual end position of the advanced mold carrier is within an acceptable error range (+/- "X" positions from the ideal center point). A determination is made to see if it is in ()). An encoder associated with each of the motors provides data that is a basis for determining the actual end position. Once the mold carrier has been placed in an acceptable position, the third step of the supply program proceeds with each operation of the motor and a set of times ("T1") that can be entered via a computer. ),
Apply the selected torque. This time interval is the time interval when the mold halves are clamped together. When this time has elapsed, each of the mold carriers will have its "0"
Return to position, that is, its start position. As shown
To return the mold support mechanism to its starting position, each of the motors has a minus sign meaning that it rotates in the opposite direction (this direction can be set and the arrow indicates a computer input). , Run at a slower speed -VS for a limited time T2 (also configurable, arrows indicate computer input). Allow the mold holder to "crack" before pulling into the "0" position at the rapid speed -VR (open profile-e.g., a constant deceleration portion ending at the start position Constant acceleration part to follow).

A second algorithm for controlling two servomotors is shown in FIG. In this embodiment, the motion control device includes a command position sequencer for each of the motors. Therefore, these motors are not electronically linked together. As shown in FIG. 18, each of the motors has a predetermined feed profile (displacement / speed /
(Acceleration profile) so that its associated mold holder can be displaced to the ideal center position (1/2 of the total distance + the selected distance at which the opposite mold holder engages and thereby stops). Are activated simultaneously.
It is ascertained that the two mold holders have stopped (an error signal can be monitored) and the actual position of each of the mold holders is determined and compared to an ideal intermediate position. If the actual position of each of the mold holders is at a distance of +/- X from the ideal intermediate position, the feed is acceptable. If not, an error signal is generated. The actual intermediate point (the position obtained by dividing the total distance traveled by both mold holders by 2) is determined, and a new ideal intermediate point is set. If one mold holder moves farther than the other (more than an acceptable difference), the controller will:
Set the scaling factor of the feed profile for one of the motors, which profile increases or reduces the displacement speed to reduce the difference in the distance traveled by the two mold holders. Next, the control device applies the necessary torque to the motor and continues the program shown in FIG.

08, the base comprising a side wall 132 and a front wall 13
5 on the top wall 134 of the section frame 11A at the front corner of the section frame defined by
09 is fixed. When in the advanced position, the axis of the baffle plate is coaxial with the axis of the closed blank mold and is located at the top of the blank mold. Upon actuation of the cam, the baffle plate first rises partially from the blank mold, and then the baffle plate rises over its remaining distance. Meanwhile, the baffle plate (baffle plate) is displaced away from the center of the blank mold, so that the inversion and neck ring holder mechanism can transport the formed parison to the blow mold. The baffle mechanism can be placed at the front of the section frame at any corner,
Unlike the conventional baffle mechanism, the fully lifted and retracted baffle (baffle plate) arms are completely positioned within the sections as shown in FIG. 19 to prevent overhanging adjacent sections. can do.

The baffle (baffle plate, FIG. 21) is a cup-shaped part 250 having an annular inclined sealing surface 252.
A body 248 having an annular sealing surface 252.
Extends around its open bottom, engages a corresponding surface 254 at the top of the open blank mold and
Seal 54. The body 248 also includes a vertical tubular sleeve portion 25 defining a cylindrical bearing surface 258 for slidably receiving the rod 260 of the piston element 262.

64 has an annular sealing surface 265 slidably displaceable within a hole 266 of the cup-shaped portion 250. A spring 268 disposed about the vertical tubular sleeve portion 256
When compressed between the collar 270 and the top of the cup-shaped portion 250 and the deflector is separated from the blank mold, the upper surface of the cylindrical head 264 remains engaged with the adjacent surface of the cup-shaped portion. The collar 270 is releasably secured to the carrier arm and the piston rod 2
It is fixed to 60.

As shown in FIG. 23, if the deflector is lowered to above the blank mold, the control unit (FIG. 25)
The collar 270 is displaced downward until the top of the collar is positioned a first distance D1 from the top surface 272 of the blank mold, at which point the cylindrical head moves relative to the cup-shaped portion. Down to define the desired gap "X" between the annular bottom surface 274 of the cylindrical head of the piston and the top surface of the blank mold (the cylindrical head is a cup-shaped portion having a vertical distance "y"). Is moving against). This applies the desired compressive force between the piston element and the blank mold to engage the inclined annular surfaces 252, 25

In this case, settle air introduced into the blank mold through the center hole 276 of the piston rod passes through a plurality of radially extending holes 278 in the cylindrical head and into a corresponding number of vertical holes 280. And into the blank mold through an annular gap between the annular bottom surface 281 of the cylindrical head and the top surface 272 of the blow mold (suitable holes 282 connecting the interior of the body to the outside air are Ensure that the cylindrical head moves smoothly relative to the body). Settle blow (settle
When the blow is completed and the gob is molded into a parison, the collar is displaced until the top of the collar is positioned a second distance D2 from the top surface 272 of the blank mold. As a result, the annular bottom surface 281 of the cylindrical head is forcibly engaged with the top surface 272 of the blank mold to close the blank mold. Once the parison has been formed (when biased to fill the internal cavity defined by the inner surface of the blank mold and the bottom surface of the cylindrical head), air is forced into the annular space of the cylindrical head (FIG. 24).

When a funnel mechanism 210 is needed, it can be mounted at another front corner. As can be seen from FIG. 26, the baffle and funnel mechanism is identical except for the direction of the barrel cam and the funnel carrier 212 supporting the three funnels 214 is attached to another actuator rod. The funnel mechanism, like the baffle mechanism, can always be in the area of its own section.

FIG. 27 illustrates one alternative inversion and neck ring holder mechanism 110. This inversion
The neck ring holder mechanism can be used with respect to the embodiments illustrated in FIGS. The end of each neck ring holder adjacent to the worm gear housing 120 terminates in a slotted mounting bracket 113 slidably received by a keyed end 109 of a support bracket 117 secured to a reversing cylinder 114. . The annular outer end 119 of the cylinder 114 (FIG. 28)
Slides in a corresponding annular groove 121 at the top of the associated outer bracket 122A. The threaded end 123 of the proximity switch or sensor 124 is threaded into a suitable hole 125 in the side bracket and secured by a nut 126. When in this position, the sensor detects the cylinder at its fully inserted position (the position where the neck ring holder retracts). Proximity switch cable 128
Extend downward through a hole (not shown) in the side bracket, and the proximity switch is protected by a cover 129. Additional pair of proximity switches 124A (FIG. 29)
Is attached to a bracket 131 fixed to the worm housing 118. These proximity switches are located below the worm gear housing 120, each facing each of the cylinders. Fixed to the end of each cylinder near the worm gear housing is a semi-circular sign 133 that, when the cylinder is positioned relative to the worm gear housing,
An associated one of these proximity switches is actuated from a first position to its second position. When in this first configuration position, the neck ring half supported by the neck ring holder is at the top of the plunger mechanism (the position where the 180 ° turnover begins) and its second position (the first direction). (In the direction about 180 ° away from), the neck ring half holds the parison at the blowing station (end of 0 ° inversion). The expressions that the neck ring is closed and that the neck ring is open are used below to describe the position of the neck ring holder / bracket / cylinder, and the control device is described with respect to one neck ring holder. The other neck ring holder is controlled in the same manner. Servo motor 108
Has an encoder that generates a position feedback signal, so that the angular position of the neck ring holder is known over its displacement angle.

The algorithm illustrated in FIG. 30 picks out operational problems during reversal. The condition of the neck ring blockage sensor 124A is such that the reversing servo 108 moves the worm forward and starts reversing the gears and the neck ring (1).
It is continuously monitored when rotating from 80 °) to the position where the reversal ends (0 °). An alert signal is generated when the neck ring does not maintain its closed position throughout this 180 ° displacement. This signal will either stop the cycle or initiate any less desired operation.

The algorithm illustrated in FIG. 31 ensures that the time for the neck ring to reach the open position is constant. The neck ring cylinder is actuated at a predetermined time (time T) in the cycle and moves from the closed position detected by the sensor 124A provided on the gear housing to the open position detected by the sensor 124 provided on the end bracket. Displace the ring at The time between these two signals is timed as “ΔT” and compared to the ideal time difference (initial time difference), and the time (“T”) that is the difference between the actual time and the ideal time difference ") The offset is sent to the controller that activates the neck ring cylinder. If the "T" offset becomes excessive or irregular,
An alarm is issued to warn the operator that maintenance is required from the stop of the cycle and to effect any desired result.

FIG. 32 illustrates the inversion algorithm. The neck ring is opened at the blowing station to release the finished bottle and the control must make sure that the neck ring is in the open position until the arm has rotated 180 ° to the blank station. By such confirmation, the inversion servo is operated so that the displacement of the desired angle is executed. At the selected rotation angle (θ1, ideal), the control device operates the neck ring cylinder to displace the cylinder (neck ring) from the open position to the closed position. Such operation is limited by limits, including that θ1 is greater than X ° and that movement of the neck ring is completed by Y °. X, Y, θ
1 can be set individually. The control device determines the actual angle (θ1, actual) when the neck ring opening sensor 124 is switched off, and subtracts the actual value of θ1 from the ideal θ1 to obtain the θ1 offset No. 1 is determined. This offset amount is sent to the control device,
Correct the operating position of the neck ring cylinder. When this offset amount becomes excessive or irregular, an alarm signal is sent.

The controller further monitors when the neck ring has reached the closed position, and provides a neck ring blockage sensor 12.
4A determines the actual value of the angle θ2 when the neck ring is detected. The cylinder is a conventional pneumatic type,
The time during which the cylinder is pneumatically displaced from the open position of the neck ring to the closed position of the neck ring can be dependent on the condition of the pneumatic cylinder. If cylinder operation is reduced, the cylinder requires more time to perform the desired displacement, and as a result of such a delay, the movable structure (neck ring structure) applies an impact force to the blank mold, and The blank mold will usually be placed off the path. A second θ1 offset degree (θ2 ideal-θ2 actual) is determined, and a second correction of the angle when the neck ring is operated is performed. When the degree of reduction reaches a selectable angle that indicates the required action, the controller generates an appropriate signal indicating that repair and / or maintenance is on track. Since each displacement angle of the encoder is a function of time, these offsets can be correlated to tracking time differences. The result of these offsets ensures that the operation of the cycle takes place at a fixed time.

The plunger mechanism, which is part of one section blank station, is illustrated in FIGS. 33 and 34, and includes three plunger canisters 62 if the machine is a triple gob machine, as shown. ing. Each of the plunger canisters has an upper cylinder portion 63 and a lower cylinder portion 64, with a plug 65 supporting an “O” ring seal 71 and an exhaust duct 7.
3 extends axially downward from the bottom surface 75 of the lower cylinder to provide the plunger canister with the required supply (plunger cooling, exhaust, plunger lowering, plunger raising, counter blow / vacuum (blow & blow machine),
Or plunger cooling (press & blow machine), lubrication,
Separate thimble rise). The canister is
The upper cylinder can be evacuated, in which case the exhaust duct and the associated duct shown are not required. For clarity, the plunger mechanism will be described for a blow and blow machine, but when describing a counter blow / vacuum, such counter blow / vacuum means cooling the plunger on a press and blow machine. Should be understood. Fixed to the top of each of the upper cylinders is a mounting plate or flange 7.

These mounting plates 77 are fixed to the upper surface of the mounting block or plate 85 by suitable fasteners 83. The mounting block or plate has holes 87 (FIG. 35). The upper / lower cylinder can pass through the hole. The mounting block is secured to the section frame 11 by appropriate bolts 89.
Is fastened to the upper surface 94. A positioning diameter portion 69 is located at the top of the upper cylinder. The top surface of the section frame has a large opening (not shown) that can receive a plunger cartridge, whether single, double or triple gob. Therefore,
The upper surface 94 of the section frame is the main surface. Preferably, the location where the mounting bracket is secured is machined to define a precisely horizontal mounting pad. The top surface of the mounting block (the area on which the flange is mounted, or pad), and its bottom surface are machined so that they are parallel, and the height of the mounting block is such that the tool can be placed at the desired height. It is preferable to set Also, by setting the cylindrical opening 87 of the mounting block to be able to engageably receive the positioning diameter portion of the plunger canister, the axes of these plunger canisters will be in their correct positions when inserted. Be placed. The mounting plate is automatically positioned (positioned) by placing diamond and round pins (not shown) on the top wall of the section frame and forming appropriate holes in the bottom surface of the mounting plate. Since the top of the plunger canister is fixed to the top wall of the section frame, heat-induced expansion does not significantly change the position of the top of the tool.

The button works with the overhang 440 of the upper mold half to stabilize the mold as it moves (as shown, this stabilization button 442 is We do not support body weight). Because the half of the blank mold is supported at the position near the neck ring groove at the position where the overhang of the mold is supported by the overhang of the mold support,
Substantially all expansion of the blank mold due to heat occurs upward from this position, and downward expansion from this position is not significant (prior art in which the blank mold is supported at a position near the top of the mold). Without the need to adjust the plunger mechanism, or neck ring, which was previously required in the structure of (1). Further, a conventional blow mold 380 suspended from the top via a downwardly projecting and annularly extending overhang 382 having a number of segments (FIG. 47).
The expansion of the blow mold halves due to heat occurs in the direction away from the finished part (threaded part), so that it is equal at both stations. The plurality of segments are supported by corresponding upwardly projecting and annularly extending overhangs provided on a support insert (not shown) of the blow mold, which also support the plurality of segments. (At a position near the groove of the neck ring).

Obviously, in the prior art, to change from one configuration at one center distance (single, double, triple gob) to the same or different configuration at different center distances, Different I. S. Often it was necessary to buy a machine or significantly modify an existing machine. The main reason is that
It is due to a complex mold opening and closing mechanism that defines different geometries. The disclosed I.S. S. The machine is a general purpose center distance machine. The machine only needs to change a number of parts to set the desired configuration / center distance, i.e. quick change of mold opening and closing mechanism, mold carrier assembly, mounting plate, intermediate plate, and possibly, plunger mechanism. By simply changing the plunger canister and the neck ring holder, it is possible to change from any desired configuration / center distance to any other desired configuration / center distance, and to change the neck ring holder and the blowing station. Thus, the mold cooling mechanism could be replaced in a conventional manner to change the form of the machine.

The dispensing mechanism shown in FIGS. 48-50 is mounted on the top surface 94 of the top wall 134 of the section frame and has a dispensing tongs head 450 which can release the bottle at the blowing station. And the X-axis slide 452
Supported by This X-axis slide can be slidably displaced along the Z-axis column 456,
It is slidably supported by a "Z" axis mounting housing or slide 454. The X and Z axes are controlled by appropriate servomotors 457,458. Regardless of its height, the bottle formed at the blowing station always has its finished part in a fixed vertical position ("Z").
Reference point) and the bottom of the bottle has a different vertical position (ZB1, ZB2) with respect to this Z reference point within the vertical height range of the bottle.
Can be located. These bottles are gripped by a take-out tongs head, discharged from the blowing station and placed on a mouth plate (dead plate) 460. This dead plate can be located at various Z positions (Z
D1, ZD2). The short bottle runs a different Z distance (Z1) than the tall bottle (Z2).
The ejection control device (FIG. 50) sets an XZ displacement profile for the ejection tong head to have an arbitrary “Z” offset distance (ZB-ZD), and performs a desired displacement.
