ADDRESS FOR SERVICE: COM4PLETE SPE.CIFICATION FOR THlE INVENTION ENTITLED: «TAKE-OUT ASSEMBLY FOR BLOW MOLDING MACHINE» The following statement in a full description of this Invention, includiftg the best method of performing it known to us
-I-
-IA-
BACKGROUND OF THE INVENTION This invention relates to a blow molding machine and particularly to one having an improved take-out assembly which removes workpieces from the forming molds and transports them to an associated material handling device.
Blow molding machines operate by charging a mold cavity with a parison of plastic material which is heated to a semi-fluid state, and is thereafter subjected to internaI pressurization through an inserted needle causing the plastic to inflate and Sconform to the inside surfaces of the mold cavity.
Blow molding machines are used to produce numerous types of articles and have been particularly used in making containers for beverages, household chemicals, etc..
One type of blow molding machine is referred to as a vertical turntable type and has a turntable which rotates about a horizontal axis. The turntable has a number of arms, each supporting a multi-piece mold assembly. The turntable is rotated continuosly S c past a number of workstations. At one workstation, components of the mold assembly are separated to expose the mold cavity. Thereafter, the .mold assembly passes adjacent to a discharge nozzle of a S’ plastic extruder which charges the mold cavity with a heated plastic parison. The mold components are then clamped together and rotated to the next workstation where a fluid (eg. air) is injected into (or I evacuated from) the mold to cause the charge to expahd and conform to the inside surface of the mold cavity. During continued rotation of the turntable, i i I’ t 1 1 C i t the mold assembly is cooled to cause the plastic material to freeze and solidify. kinally, the mold assembly is opened and the finished workpiece is removed by a take-out assembly. In accordance with the prior art, take-out devices conventionally includes a hook or rod which engages the workpiece and transports it to an associated material handling system such as a conveyor. The conveyor transports the workpiece to other workstations for flash removal, labelling, filling, etc.
Although the presently available blow molding machines operate satisfactorily, there is a need to provide such machines with an improved take-out assembly which more positively removes the workpieces and more accurately positions them with respect to an associated material handling system such as a conveyor.
SUMMARY OF THE INVENTION In accordance with the present invention, a r C C take-out assembly is provided which is particularly adapted for use with vertical turntable type blow S molding machines. The take-out assembly according to this invention includes a turntable having a number I of extending arms. At the end of each arm are vacuum operated suction cups which adhere to the workpieces Swhen a vacuum signal is provided. The arms extend and retract at the appropriate time during rotation 0 of the turntable to properly position the suction cups to pick up and drop off the workpieces. The S* present take-out assembly reliably engages the i workpieces and enables the workpieces to be 4 accurately positioned upon a conveyor.
-2- 1 r In accordance with another feature of this invention, the take-out assembly is provided with means for enabling it to be moved away from its normal operating position so that workpieces can be removed from the blow molding machine manually, which is frequently desired during machine start up, tuning, retooling etc. Rotation of the take-out assembly turntable is coordinated with rotation of the blow molding machine turntable so that the suction cups are properly oriented to engage the workpieces at the appropriate point in the production cycle.
Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from the subsequent description of the preferred embodiments and the appended claims, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION A blow molding machine with an improved take-out assembly according to this invention is shown in Figures 1 and 2, and is generally designated by reference number 10. Machine 10 generally comprises blow molder turntable assembly 12;’ and take-out assembly 14.
As is best shown in Figure 1, blow molder turntable assembly 12 rotates about a horizontal axle 16 and includes central turntable 18 with a number of radially extending mold .mounting arms 20. Blow molding machine 10 is designed to rotate continuously S. such that turntable 18 rotates at a constant speed which does not necessitate intermittent stops as each 0 -4mold assembly 22 passes the various workstations.
Rotation of turntable 18 is controlled by motor which drives sprocket 62 through chain 64.
At the end of each arm 20 is a two-part mold assembly 22, which has fixed portion 24 and movable portion 26. Portions 24 and 26 are connected by hinge 36 which enables movable portion 26 to be opened to expose mold cavity 28. Internal mold cavity 28 may have any number of configurations to form various workpieces. Workpieces 46 shown by the Figures is a conventional household chemical bottle such as used to contain laundry bleach.
During the production cycle, movable portion 26 of the mold assembly 22 is periodically opened to expose mold cavity 28, and closed during forming of the workpiece. -The opening and closing of mold assembly 22 is controlled by cam plate 30, shown in Figure 2, which acts on. follower 32 and tie rod 34.
Movement of tie rod 34 causes movable mold portion 26 to open and close about hinge 36. Since internal mold cavity 28 is pressurized when the parison is being inflated, it is necessary to lock the mold portions together. Locking occurs by the action of latch arm 38 which rotates about pivot 40, and is moved by cam follower 42 which travels along cam plate 44. At the appropriate point in the operating cycle, as shown in Figure 2, latch 38 moves in D position to engage a surface of mold portion 26,thus locking the components of mold assembly 22 together.
Blow molding machine 10 is used with an associated plastic extrusion machine which is shown in phantom lines in Figure 1 and is generally Sdesignated by reference number 50. Machine 50 is of S. conventional design and employs a rotating screw ml cvt 2 s rsurzdwhnth aisii beng iflaed, t i necssay toloc themol which causes frictional heating by shearing pelletized plastic raw material and discharge it through a nozzle in a heated molten state.
During rotation of turntable 18, segments of molten plastic from extrusion machine 50 are deposited within the opened mold assemblies 22. This step occurs at about the one o’clock rotated position of turntable 18, as shown in Figure 1. After the parison is deposited within mold cavity 28, mold assembly 22 is closed and locked, and inflation pin 52 is inserted as shown in Figure 9. The parison expands as air is introduced through inflation pin 52 until it conforms to the internal surfaces of the mold cavity 28 which defines the final configuration of workpiece 46. As shown in Figures 9 and 10, mold cavity 28 forms flash portion 54 which is later trimmed away from the remainder of the workpiece in a subsequent operation.
During continued rotation of turntable 18, mold portions 24 and 26 are cooled to cause the .plastic material to solidify. At approximately the ten o’clock rotated position as shown in Figure 1, mold assembly 22 is unlocked and cam plate 30 causes S movable portion 26 to open to expose workpiece 46.
At approximately the eleven o’clock position, ejector pin 56 acts on flash portion 54, as shown in Figure 10, to separate the workpiece from mold portion 24, Sthereby breaking adhesion between the workpiece and S mold. At a subsequent step in the production process, take-out assembly 14 described in detail below removes workpieces 46 and transports them to an associated material handling system.
The details of construction of take-out 0 assembly 14 are best explained with reference to -6m m Figures 1 through 8. Take-out assembly 14 is mounted to support frame 70 which is fixed with respect to the remainder of blow molding machine 10. Support frame 70 is elongated in the vertical direction and includes a pair of separated guide bars 72. Guide bars 72 enable take-out head 74 to be moved vertically from its normal working position so that workpieces may be removed from blow molding machine manually. Such manual unloading is particularly desired during tuning of dies, initial startup, etc.
Take-out head 74 is slideable along guide bars 72 and its positioning is set by rotation of screw 76 which is controlled by take-out positioning motor 78.
Take-out head 74 has a threaded base which receives screw 76 so that it moves along the screw as it is rotated.
Shaft 80 is supported at opposite axial ends by bearing assemblies 82 and 84 of take-out head 74.
Shaft 80 is hollow for the conduction of vacuum transmitting tubes, as will be described below.
Turntable 86 rotates with shaft 80 and includes a plurality (six shown) of pick-up units 88. Pick-up units 88 include linear bearing 90 which enables portions of the pick-up unit to extend and retract, as desired. Shaft 92 extends through bearing 90 and Shas a hollow end portion which receives thre’aded 4» shaft 94. Threaded shaft 94 supports pick-up head 96 which has four separated suction cups 98. Adjustment nut 102 is threaded onto shaft 94 and is received by hollow shaft 92, and enables the axial positioning of pick-up head 96 to be adjusted. pesitioni-4xed bye et s.w n Head 104 is attached to the C end of shaft 92 opposite pick-up head 96. Coil r spring 106 is positioned between bearing 90 and head -7- :flrr S104 to resiliently bias shaft 92 (and pick-up head 96) in a radially inward direction, relative to turntable 86.
The radial positioning of pick-up heads 96 is controlled through the interaction between cam followers 110 and cam plate 112, which is best shown in Figures 7 and 8. Each of cam followers 110 are coupled to heads 104 by links 111. Cam plate 112 is fixedly mounted with respect to take-out head 74.
The positioning of cam followers 110 associated with each of the individual pick-up units 88 is shown in Figure 8. The configuration of cam plate 112 causes pick-up heads 96 to be retracted at the position where workpieces 46 are being unloaded, and extended after the workpieces are engaged.
Suction *is applied to pick-up heads 96 through flexible hoses 116 (one shown) which are held in position by blocks 114 which are mounted to turntable 86 adjacent each of pick-up units 88.
Hoses 116 are routed through the internal bore of shaft 80 and communicate with rotary timing valve S118. Timing valve 118 has a fixed portion 120 and a rotating portion 122. The individual hoses 116 are S* connected to rotating portion 122 via radially displaced ports and a source of vacuum is connected to a port in fixed portion 120. In a well known manner, valve portions 120 and 122 have internal bores which are blocked or unblocked as they rotate .i relative to each other to selectively open or close the vacuum signal to appropriate hoses 116 in a timed manner, thus providing a vacuum signal to the hoses when.the associated pick-up head 96 is within a predetermined range of rotated positions.
1 1 .^.range positions.
-8- -9 1 i I::1 Since (in the embodiment shown) take-out assembly 14 has six take-out heads 74, and blow molding turntable 12 has twelve mold assemblies 22, it is necessary to rotate turntable 86 at twice the rate of rotation of blow molder turntable 12. In addition, it is necessary to coordinate the position of the two turntables so that the elements properly engage in a timed manner. Such coordinated rotation is provided by sprocket 124 which rotates with shaft 16 and communicates with drive gear 126 through chain 128. The rotary motion is transferred to internally splined shaft 130 which is supported by bearing 132.
Since it is necessary to permit take-out head 74 to translate vertically, a smaller diameter externally splined shaft 134 interfits within shaft 130 and is rotated by drive coupling 136 which is driven by rotation of shaft 16.
Take-out assembly 14 is preferrably employed in connection with a conveyor type material transfer system which transports workpieces 46 to a subsequent work station or storage area within the work cycle of the workpieces. One such type of conveyor is shown inFigures 4 and 6, and is generally designated by reference number 140. Conveyor 140 has a pair of :It• separated endless belts 142 which rotate around separated sprockets 144. Conveyor 140 defines an open central area which provides clearance for passage of pick-up units 88.
During operation of take-out assembly 14, turntable 86 is rotated in a coordinated relationship with blow molder turntable assembly 12. When workpiece 46 reaches approximately the 11 o’clock position of rotation of turntable 12, as shown in e Figure 1, cam plate 112 causes one of pick-up heads a~ f i i il -9r i 96 to extend into close proximity with the workpiece.
At that point in the rotation of turntable 86, the vacuum source is communicated to the suction cups 98 such that they adhere to workpiece 46. Thereafter, workpiece 46 is brought to an overhead position where pick-up unit 88 is positioned between conveyor belts 142. At that position, the vacuum source is disconnected from pick-up head 96 to enable the workpiece to separate from the pick-up head and be transported along conveyor 140 to a subsequent work station. Af’Lr releasing workpiece 46, pick-up head 96 is retracted to provide clearance as it moves past mold assemblies 22. Each of the individual pick-up units 88 operate in the above described manner in a continuous fashion such that a pick-up head 96 is presented for each of the workpieces 46 produced by blow molder turntable assembly 12. The use of take-out assembly 14 enables the workpieces to be reliably removed from the molds and precisely positioned in registry with conveyor 140.
While the above description constitutes the preferred embodiments of the present invention, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope and fair meaning of the accompanying claims.
