Description
Technical field
The present invention relates to the equipment of the Angle Position of the rotation plate rail for measuring transport box, equipment is included
Plate rail is rotated, rotation plate rail surrounds central axis unitary rotation, and central axis has the rotation axis of axial orientation；
Angle transducer, angle transducer have wheel measuring axis, and angle transducer is used to measure the angle for the Angle Position for indicating plate rail
Degree.
Background technique
The manufacturing equipment of production line high-volume manufacture bottle has the multiple processing for being installed on production line mechanical.Each processing
Machinery has container Automatic Conveying device.Therefore, container is preferably continuously transported to equipment export from equipment entrance.
Within the scope of the invention, the processing of the rotation plate rail more particularly to equipped with transport box is mechanical.Convey plate rail with
Central axis is fixed together in terms of rotation, and central axis is rotated by motor drive.
These different mechanical synchronization operatings can make container enter another machinery from a machine automatization.
In addition, certain processing are mechanical to be furnished with movable part, movable part must be same with the conveying device of the manufacturing equipment
Step.In the case where blowing mechanical, movable part is, for example, to extend stick, for drawing container.In the case where displacement delivery wheel,
Movable part is, for example, container crawl fixture.
Until recent, synchronizing for the different movable parts of equipment is entirely to be carried out with machinery, such as with cam or movement
Transmission mechanism carries out.
But hereafter certain movable parts are individually controlled by motor.These work can be used in this variation of manufacturing equipment
The electronic synchronizer of dynamic component and manufacturing equipment other component.Therefore, replace mechanical synchronization with electronic synchronizer, it can be mechanical by reducing
The number of components, reduce the production cost of manufacturing equipment.In addition, this can be by reducing the quantity of wearing terrain and eliminating certain events
Hinder mechanical factor, exempts certain maintenance operations.
To make the movable part carry out this electronic synchronizer, it is necessary to determine the angle position of the rotation plate rail of transport box at any time
It sets.To this end it is known that using angle transducer, also known in the title of " rotary encoder ".
Angle transducer has measurement axis, and measurement axis connection is in the upper end of the central axis of driving plate rail.This equipment is not necessarily to
High-precision operate synchronously is satisfactory.
But, it has been found that the measurement that angle transducer carries out has error, in the actual corners of the Angle Position and plate rail that measure
Up to 6 ° of errors between position.Although these measurement error reasons cannot establish for certain, we guess mechanical top
Concentricity defect is problem place.
In fact, there are many large-scale components for plate rail assembly, they are installed around the rotation axis of plate rail well-balancedly, example
Such as, blowing is mechanical is equipped with movable crawl arm equipped with model or delivery wheel.In addition, especially turning when the activity of these large-scale components
When dynamic, during machine operation, Mass Distribution is easy to change, so that the Mass Distribution for changing the rotation axis around central axis is equal
Even property.This leads to influence of unbalance on center shaft.
In addition, the upper end of central axis is arranged on plate rail with biggish distance, such as three meters or more of distance.Cause
This, axis is easy slight curving deformation under influence of unbalance.This causes the rotation axis of the upper end of axis to rotate every time in plate rail
Shi Jinhang radial vibration.Alternatively, angle transducer is supported by a fixed support, the rotation axis of measurement axis keeps radial solid
It is fixed.This cause plate rail rotate during central axis relative to measurement the non-centering of axis.Therefore, plate rail rotation during, measurement axis with
Central axis is not exclusively coaxial.In this way, the centering defect of the rotation axis of the rotation axis of the upper end of central axis and measurement axis, holds
Easily according to the rotational angle of plate rail, dynamic change occurs.Therefore, in the same change of team dynamic change occurs for measurement error.
In addition, the upper end of central axis is easy by periodical torsion, to actually make the angle of the upper end of central axis
The Angle Position of position deviation plate rail.
For the control that certain movable parts for example extend stick, this error is totally unfavorable.For example, extending the upper of stick
It rises and is easy lag, so that extending stick when it is considered as being loaded by an output wheel and being inserted into always in a reservoir.Therefore, container
There is the container of damage, whole equipment is easy safe shutdown, or even mechanical certain components are damaged.
In addition, movable mass control is formed in plate rail when rotating every time, moved relative to plate rail, alternately close to and from
Open the rotation axis of central axis.For example, it is particularly the case for the model of blowing machinery, it is opened then when plate rail rotates every time
Molding.The continuous movement of each movable mass on the plate rail of rotation, causes the moment of inertia of plate rail to change repeatedly.This table
It is now the revolving speed of center axis with the frequency of every revolution times, is fluctuated in mean speed or so.
It was found that this fluctuation does not allow to control movable part glibly.

It sets.For this purpose, equipment is furnished with angle transducer 66, well known, referred to as " encoder ".
As shown in Figures 3 and 4, this angle transducer 66 has wheel measuring axis 68, and wheel measuring axis has axial orientation
Axis G.Wheel measuring axis 68 drives detection device (not shown), and detection device is received in fixed shell 70.According to unrestricted
Property embodiment, be related to optical sensor, magnetic sensor or any other type be suitable for measure wheel measuring axis turn
The sensor of dynamic angle.
Angle transducer 66 is arranged to the angle of the Angle Position of the plate rail 12 of measurement expression rotation processing machinery 10.
It was found that angle transducer 66 is directly connected in the upper end of the central axis 14 of rotation processing machinery 10, cannot obtain
Sufficiently accurate measurement result on the whole circle of plate rail 12.
In fact, half model has very big quality, e.g., about tens of kg.Only it is opened in angle sector portion 18
When, moulding unit 16 will appear Mass Distribution imbalance around rotation axis B, because the half model in die sinking position compares at this time
Half model in die-closed position is slightly closer to rotation axis B.
In addition, each moulding unit 16 is continuously opened and molds the change for leading to the moment of inertia of rotation processing machinery 10
Change.
This leads to the vibration of the central axis 14 of rotation processing machinery 10.Amplitudes of these vibrations because it is very big and farther away from
Plate rail 12.But, the central axis 14 of rotation processing machinery 10 can increase 3 to 4 meters on plate rail 12.
To solve this problem, the present invention proposes a transmission chain, and wheel measuring axis 68 and central axis 14 is replaced to turn
Dynamic aspect is directly connected to, and the transmission chain has a driving wheel of at least one and central axis radial offset, for example, pulley or
Gear mechanism.
Therefore, measurement error caused by eliminating due to the dynamic centering defect of wheel measuring axis 68 and central axis 14.
Transmission ratio between central axis 14 and wheel measuring axis 68 is preferably two power.For example, when transmission ratio is 1:4
When, it is known that central axis 14 turns around, 68 turn of four circle of wheel measuring axis.Therefore, angle transducer 66 issue signal be easy by
Electronic control unit (not shown) is handled, and electronic control unit is suitable for finding out the rotational angle of central axis 14.

Axis 68 is parallel to central axis 14 here and is extended.
Central axis 14 has the first driving wheel 74, and the first driving wheel and the second driving wheel 76 cooperate, to move wheel measuring axis
68 rotations.Second driving wheel 76 is directly installed on wheel measuring axis 68.Therefore, wheel measuring axis 68 is directly driven by central axis 14
It is dynamic.Second driving wheel 76 is relative to 14 axialy offset of central axis.
Here, two driving wheels 74,76 are formed by direct meshed gears.
In the unshowned other embodiments of the first embodiment, driving wheel is by by transmitting flexible band connection
Pulley is formed.
According to another unshowned embodiment of the first embodiment, wheel measuring axis is arranged to its axis in
The axis shape of mandrel is at an angle.Therefore, driving wheel is formed by the gear with concurrent axis.
By means of being suitble to the radial running clearance of this motion transfering device, various move radially of central axis 14 will not be right
Wheel measuring axis 68 generates stress.
In addition, in order to avoid measurement error caused by 14 torsional deflection of central axis, and to move the radial of central axis 14
Dynamic amplitude is small, and the first driving wheel 74 is preferably in axial direction arranged to the upper free end than central axis 14 closer to plate rail 12.Example
Such as, the axial distance between plate rail 12 and the first driving wheel 74 is less than about one meter.
Second of embodiment of the invention according to Fig.4, wheel measuring axis 68 and rotating intermediate shaft carry out direct
Rotation connection.The rotating intermediate shaft is radially arranged to keep certain distance with central axis 14.Therefore, the rotating intermediate shaft is passing
It is arranged between wheel measuring axis 68 and central axis 14 in dynamic chain.
Advantageously, the rotating intermediate shaft is designed to not convey any container.In this way, rotating intermediate shaft does not suffer from inertia
Momentum change, in addition, its moment of inertia is less than the moment of inertia of the device formed by central axis 14 and its plate rail 12, because not depositing
In container transport plate rail.
The jackshaft is for example being arranged between motor 32 and central axis 14 in transmission chain.Without limitation, such as Fig. 4
Shown, the jackshaft is formed by the output shaft 36 of decelerator 34 here.In fact, it was found that this device can enable
People reduces the measurement error of angle transducer 66 very satisfiedly.
Wheel measuring axis 68 is here arranged as output shaft 36 is parallel to, and there are two coplanar transmissions by tool for wheel measuring axis 68
The movement transferring of wheel is rotatablely connected with output shaft 36.Here, the shell 70 of angle transducer 66 passes through fixed flange 77
It is fixed on support plate 43.
In the embodiment shown in the figures, it is related to two gears 78,80, they are separately mounted to wheel measuring axis 68 and defeated
On shaft 36.The two gears 78,80 engage directly with one another, rotate so that wheel measuring axis 68 is driven by output shaft 36.
Therefore, wheel measuring axis 68 is rotatablely connected by transmission chain with central axis 14, and the transmission chain has opposite
In multiple driving wheels of 14 radial offset of central axis, in particular, relative to input gear 44, gear 78 and driving wheel 76.
When the transmission ratio between the output shaft 36 of decelerator 34 and central axis 14 is not two power, this equipment
It is highly beneficial.Pass through the gear 78,80 for selecting that there is suitable diameter, it is ensured that the transmission between central axis 14 and wheel measuring axis 68
Than the power for being entirely two.
According to the first modification, is replaced with pulley and move the gear for transmitting flexible belt cooperation, can get identical superiority.
Transmission ratio according to another modification, between the central axis of output shaft and the rotation processing machinery of decelerator
When being two power, wheel measuring axis can be made to be arranged to substantially coaxial with the output shaft of decelerator.In this case,
Wheel measuring axis is rotatablely connected by connector and jackshaft.
According to another aspect of the present invention, it has been found that the revolving speed of plate rail 12 with moulding unit 16 be opened with mold and
Fluctuation.This fluctuation cannot control the movable part by Motor Control glibly.In fact, in this case, these work
Dynamic component itself is subjected to identical velocity perturbation in its movement.
In order to solve this problem, angle transducer 66 can be filtered perhaps with processor or with electronic processor
The signal of sending.
But, it has been found that so that a transmission device is arranged in wheel measuring in transmission chain with movement transmitting flexible belt
Between axis 68 and central axis 14, the die sinking and molding for being easy to mechanically filter moulding unit move these generated speed
Fluctuation.Adjust the dress for the tension for making the tension adjustment of movement transmitting flexible belt to the periodical rotation speed change that may filter that central axis 14
It sets, especially can get this filtration.
Therefore, it has been found that the equipment of the angle transducer 66 of second of embodiment according to the present invention, it can be highly effective
Filter the fluctuation of speed in ground.In fact, the tension for being commonly applied to the first transmission belt 41 is already adapted to effectively filter revolving speed
Fluctuation.Therefore, this equipment is without carrying out any special adjustment.
Therefore, equipment of the invention can accurately measure the Angle Position of the plate rail 12 of rotation processing machinery 10, very simple, nothing
Need the attachment device that use cost is high.
In addition, the present invention it is also proposed that mechanically effectively filtering plate rail 12 the fluctuation of speed solution, as long as
Adjust the tension of a movement transmitting flexible belt.
The present invention is illustrated with reference to rotation blowing machinery.Obviously, other rotating machineries of manufacturing equipment may benefit from
The present invention.Therefore, rotation processing machinery can be formed by filling machine.
It is can also be applied to the delivery wheel with pivotal arm.In fact, this delivery wheel is also subjected to moment of inertia change
Change, the measurement error easy to form that blow the measurement error that mechanically finds with rotation similar.
