Description
The present invention relates to be equipped with on the passage of several work stations, transport a kind of preform conveyer of preform.
In order to form a kind of hollow product,, obtain a kind of in advance by the injection mould that is adopted for the preformed device of blowing mould (also claiming the parison device) as final finished such as bottles.This device is disclosed among the Japan Patent NO.89470/1975, and it is equipped with and is rotating and during heating, can transmit the first passage of preform and accept first passage the second channel of preform of confession, and when rotating, transmit the blowing mould of a plurality of radial arrangement.This device is difficult to supply air and electric power to the blowing mould that is sent when rotating, this can cause the equipment cost costliness.In this respect, the device that is disclosed among the Japan Patent NO.297231/1989 is just more favourable.In this device, preform receiving station, heating station, blowing mould station and put the mould station and all be distributed on the circular passage with stationary state, and preform transmits along this passage.
Transmitting preform to each work station, because during each work station processing, need stop to infeed preform, this just need transmit preform intermittently.
Be interrupted under the situation of supplying with preform, just need setting the dwell time of confession part maximum process times with a work station.For this reason, just need during heating stop for part to each work station, because usually it will melt the longest process time, so a long forming period is unfavorable to requiring.In addition, because supply the part dwell time to depend on the process time of a work station, condition of work just becomes very complicated such as the heating condition at other work stations.And a cut-off part is than the control for part is complicated more continuously, and And can increase energy resource consumption.
So, an object of the present invention is to eliminate the conveyer that the problems referred to above And in relevant technology proposes a kind of preform, it can be when rotating rotating disk continuously, enable the preform that stops on a work station, And can adopt a kind of novel piece-supply system to quicken on passage or supply preform with slowing down.
Another object of the present invention provides a kind of simple structure of very reliable preform conveyer again, is to stretch by the continuous rotatory force of rotating disk with cam and cam follower to quicken, slow down and stop the supply of preform for the Zhi Cheng Bei And of part.
The present invention also has the another one purpose, and a kind of conveyer of preform is provided, and the joiner structure of clamping preform that its can be enough improve enables to clamp at short notice and unclamp preform, for this reason, helps shortening forming period.
For reaching this purpose, the present invention proposes a kind of preform conveyer, and it can transmit preform on a kind of passage that various work stations are housed, and this device has:
A rotating disk;
Fixture with the rotating disk positioned opposite; Be contained in first cam and second cam on the fixed head;
A supporting arm, it can shrink by free Shen Kai And in the radial direction of rotating disk, and by the supported end that rotating disk is supporting swingably, it is equipped with by first cam follower of first cam domination and second cam follower of being arranged by second cam; And
A coupling that is arranged in the supporting arm front end is so that the neck of mobilizable supporting preform;
Supporting arm is according to the back location of first cam follower, and flexible ， And is according to the position of the back of second cam follower on axial direction, and the supported end swing around as fulcrum like this, just can make the supply of preform be quickened, and Jian Shu And stops.
According to the present invention, because the supported end of supporting arm is supported by rotating disk, supported end and rotating disk integrally constantly rotate.
In any case, supporting arm is because of first cam and first cam follower, and the relation between second cam and second cam follower, and it is not to supply part continuously, but be sandwiched in front ， And and be around as the supported end swing of fulcrum and flexible with a speed that equates.If desired, the supply of preform can be quickened, slow down.It also can borrow the preform on the passage of stopping that stretches of the synthetic and supporting arm of oscillating motion.
In the distance between the back location of first cam and first cam follower, first cam is just stretched out supporting arm, when distance is short, just shrinks supporting arm.
It is mobile that second cam quickens supporting arm is by keeping the back location of second cam follower, and it has a distance with center of rotation according to rotating disk, and distance near the time, the supporting arm that just slows down mobile.
Supporting arm is made up of a swing part, it is according to the position of the second cam follower back, swing with respect to rotating disk, a pole, it can linearity supported movably by swing part; And is at its preceding end bearing one coupling, for this reason, a straight line movable part is being supported by swing part, like this, pole moves as straight line and the guiding transmission mechanism according to the linear guide pole that moves of linear movable part in same direction according to the position of the first cam follower back.If guiding transmission mechanism fixed linear movable part is to pole, then stroke Huan of pole equals the stroke of linear movable part, for this reason, unless the position of first cam is away from the rotary motion trace of supporting arm supported end, this just can not guarantee the stroke of stretching out and shrinking be scheduled to, this just means that there is very big expansion the neighboring of fixed head.
So, a kind of guiding transmission mechanism, it can make the shift motion of pole bigger than the stroke of linear movable part, and that is reasonable.A kind of guiding transmission mechanism like this, for instance, its composition is: first connecting rod, the one end is linked swing part rotationally, second connecting rod, and the one end is pivotally connected to the front end of pole, and the other end is pivotally connected to the other end of first connecting rod, the 3rd connecting rod, the one end is pivotally connected to linear movable part, and the other end is linked on the part of first connecting rod rotationally.
If hollow shaft is coaxial with the fixed axis of supporting fixed head, and circumjacent fixed axis, rotating disk is fixed on the top of hollow turning cylinder, and its underpart is parallel with fixed head, and this just might make this device compact.
Like this, fixed head is equipped with first cam path and second cam path, and it is a circular passage facing to the surface of rotating disk, first and second cam followers are moved in corresponding cam groove as roller, thereby supporting arm is able to smooth transmission.
In the present invention, the coupling of clamping preform neck also has improvement.
The preform coupling is to form like this: many clips round the preform neck are arranged, so that clamp preform, they are connected to neck with hinge, so that unclamped when rotating; A kind of rotation controling mechanism, it makes clip rotate each clip and rotate each clip in separated direction in the direction of drawing close mutually, so, when many clips rotate make its mutually near the time, just surround neck, and when their rotations are separated from each other clip, just unclamp from neck.Because the rotating operation of clip is realized quite rapidly, this just might eject preform by rapid Jie Shou And, impels and shortens the cycle that is shaped.
If receiving unit touches the major diameter lower surface partly that neck forms with the lower part, whereabouts that this just might prevent preform safely.
If each clamp hinge is connected on the stationary cylinder, the consisting of of its rotation controling mechanism: a slip ring, it vertically moves along stationary cylinder, a pull bar, its two ends are correspondingly supported by slip ring and stationary cylinder rotationally, rotate clip, make when slip ring is raised, clip is separated from each other; And when slip ring is fallen, rotate clip clip is drawn close mutually.
If imaginary line is linked the run-on point on top, pull bar is linked slip ring from this point, on the run-on point of bottom, pull bar is connected to clip, selecting like this is to make it not by the hinge portion and the stationary cylinder of clip, like this, draws close each other when clip is rotated, be separated from each other when clip is rotated, this just might prevent that pull bar is from dead point disengagement that can not transmission.
If a spring is pushed down slip ring, enable Huan and descend surely, the state that this just might keep clip to draw close mutually promptly is in the preform state of clamping.This might rotate clip, and the last pushing mechanism of slip ring is separated from each other clip to And on the work station with being contained in.
If a cylinder that can vertically move is contained in the inboard of stationary cylinder, might adopt a kind of blowing mould supercharging medium, to keep the state of being close to of neck.This also might provide a kind of seal, to keep the sealing of movable cylinder lower end.If on stationary cylinder and between the flange of the upper end of the removable cylinder that protrudes upward from stationary cylinder, adorn a spring and a member, be used for depressing the flange that is contained in the removable cylinder in blowing mould station, this just might prevent the leakage of supercharging medium safely.
This improvement ， And of coupling strictly do not use the conveyer supporting arm the acceleration for part operation, slow down and stop on, and when using it on the device that adopts another kind of piece-supply system, it also can impel the shortening forming period.
From following optimum implementation, together with its accompanying drawing, above-mentioned and other purpose, characteristics and advantage of the present invention can seem very clear.

In Fig. 2, a circular fixed head 10 is securely connected on fixed axis 12.Fixed axis 12 is fixed on the bottom of this device with bolt 16 and 18.
Round fixed axis 12, to be supported movably by bearing 22, one hollow turning cylinders 20, it is concentric with fixed axis.Hollow turning cylinder 20 24 has a rotating disk 40 in the top, and rotating disk 40 is connected to hollow turning cylinder 20 securely, like this, just can rotate together with hollow rotating shaft round fixed axis 12.A transmission gear 28 is fixed on the lower end 26 of hollow turning cylinder 20.Transmission gear 28 is meshed with the travelling gear 32 that is fixed on motor 30 output shafts.
Lower surface in the face of the fixed head 10 of rotating disk 40 is provided with a lobe plate 50, and first cam 52 aisle different with second cam 54 is housed therein.In the present embodiment, first and second cams 52,54 are provided with cam path, and its shape is described later.
As shown in Figure 1, rotating disk 40 is equipped with many, for example 20 supporting arm 60(60a to 60t), all be circumferentially extending.The corresponding supporting end face 62 of supporting arm 60, it is distributed on the rotating disk 40 regularly, and And is being supported swingably by rotating disk 40, and supporting arm 60 can be stretched out and shrinks along the axial direction of the described structure in back.As shown in Figure 3, the composition of supporting arm 60 is: a swing part 70, it is being swung and is touching rotating disk 40 And and swung by second cam follower 82 along with the aisle of second cam 54, two poles 90 can linearity be supported movably by swing part 70, and a linear movable part 100 is connected on first cam follower, it is along with the aisle ， And of first cam 52 is being supported by swing part 70.Like this, can move as straight line along the same direction of pole 90, a coupling 110 that is fixed on pole 90 front ends, clamping preform 1 movably just in such a way, and a guiding pole 90 is made the guiding transmission mechanism 120 of linear steering.
Each supporting arm of 60a to 60t all has a swinging axle 72 at supporting end face 62 places, and it by rotating disk 40 rotatably supports, sees shown in Figure 3.Guide section 74 is fixed on the swinging axle 72.Guide section 74 has first guide holder 76, and it is supporting two poles 90 movably by two hole 76a And and is being formed.Guide section 74 also is equipped with second guide holder 78, and it comprises a pair ofly stretches out from first guide holder, 76 upper ends, supporting member 78a separated from each other, and be fixed in a axis of guide 78b between a pair of guide 78a.The linear seat 100 that moves can linearity supported movably by axis of guide 78b.A rest pad 92, the front end ， And that is fixed to pole 90 leads with guide section 74.Coupling 110 is contained in the supporting section 74.With this coupling 110, catch preform 1 And to be sent on the predetermined passage.
The swing arm 80 of the shape of cranking arm is fixed to the top of swinging axle 72, sees shown in Figure 4.Along with second cam follower 82 of second cam, 54 aisle walking, be the top that is contained in swing arm 80.And the function of second cam follower 82 is as roller, and it can rotate with respect to swing arm 80.Like this, swinging axle 72 just can be swung with respect to rotating disk 40 by the displacement of swing arm 80.
Oscillating motion be by the position uniformity of the position of the supporting end swinging axle 72 of supporting arm 60 and the second cam follower back determining, so with these positions of control, just can obtain the acceleration and the deceleration operated for part of supporting arm 60.
Can obvious moving motion with reference to Fig. 5.In Fig. 5, symbol A represents the motion track of supporting arm supporting end face 62, and promptly swinging axle 72, the center of rotation O of rotating disk 40, and C is the rotation direction of rotating disk 40.In the present embodiment, the direction that the direction of swing arm 80 is stretched out perpendicular to supporting arm 60, but this direction can be with another angle of intersection fork.Track B when the back of second cam follower draws one during with the track A concentric circles that moves, and shown in Fig. 5 (A), supporting arm 60 just and rotating disk 40 constant speed movement.If the distance between the position of second cam follower, 82 back and the center of rotation O increases (the track B of back is in the outside of motion track A) shown in Fig. 5 (B), just obtain the acceleration of supporting arm 60 motions.On the other hand, if reducing (the track B of back is in the inside of motion track A), the distance of the position of the back of second cam follower 82 and center of rotation O shown in Fig. 5 (C), just obtains the deceleration of the motion of supporting arm 60.It also can be on certain position, and with the moving of supporting arm 60 of the slowing down preform 1 that stops, promptly the front end of supporting arm 60 is stayed same position and stretched, and this will be narrated in the back.The curve shape of second cam 54 will be determined to such an extent that can quicken and slow down.For example, the flute profile that second cam 54 is got, as shown in Figure 1.
Straight line movable part 100 is the L shape, and it is equipped with a long leg 102, and it stretches in vertical direction, a short-leg that can stretch in the horizontal direction 104 is arranged, as shown in Figure 3.First cam follower 106 is contained in the upper end of long leg 102.The effect of first cam follower 106 as a roller, it can rotate with respect to the passage that long leg 102 reaches along with first cam 52.Long leg 102 is being supported movably by second guide holder 78 of guide section 74, and it is equipped with a chute 102a, and guide roller 78b slides by it.Long leg also has chute 102b and 102c, and pole 90 slides by it, in case the phase mutual interference of 90 of stopping bar.Compression helical spring 108 is enclosed within on wherein pole of pole 90, and it is in the inner surface 74a of guide section 74 and long leg 102 facing between the inboard of surperficial 74a, accelerates straight line thus and moves seat 100 and leave from fixed axis 12.
The stroke of stretching, contract of supporting arm 60 is to move seat 100 the journey of moving by straight line to obtain, and straight line to move seat be to move together for the guiding transmission mechanism 120 and second cam follower 106.
Guiding transmission mechanism 120 is made up of three connecting rods, that is, and and 122, the second connecting rods 124 of first connecting rod and the 3rd connecting rod 126.The end 122a of first connecting rod 122 is supported by swinging axle 72.Swinging axle 72 rotatably supports a rotation head 128 of a following end of swinging axle.First connecting rod 122 is to be supported swingably by a swing pivot pin 130 by the swing head.
Swing pivot pin 132 is contained in the other end 122b of first connecting rod 122, for making corresponding swingably end 122b and the 124b that is connected to first and second connecting rods 122 and 124.Second connecting rod 124 has a swing pivot pin 134, and it is positioned at the other end of 124a, and And is being supported by swing pivot pin 134 swingably by supporting base 92.
Third connecting rod 126 is further supporting swingably by the swing pivot pin 136 of end 126a, and And moves seat 100 by straight line and swings pivot pin 138(at other end 126b by one) short-leg 104 supporting swingably.Therefore, straight line moves seat 100 reciprocating motion and is sent to supporting base 92 by the guiding transmission mechanism corresponding to relevant connecting rod 122,124 and 126.
A kind of like this reciprocating motion is caused by the distance between the supporting end face that changes supporting arm 60,, changes the distance of 106 of the swinging axle 72 and first cam followers that is.The position of preform 1 is that the front end by supporting arm 60 supports, and it also changes with the oscillating motion of supporting arm 60, this be because of the action of second cam follower 82 caused.For this reason, preform 1 is stretched over when the longest at supporting arm 60, does not always leave center of rotation farthest.So, just need the stroke of decision supporting arm 60 to come the distance of regulation center of rotation, with due regard to the lead of second cam follower 106 of second cam, 54 passages operation to preform 1.The flute profile of first cam 52 as shown in Figure 1, this decision is in order to obtaining the pre-routing of preform 1, And has considered the shape of second cam 54.The curve that first cam 52 draws is crossed the peripheral proximity of fixed head 10 and is stipulated that a stroke ， And limits the motion of coupling with this, otherwise it can break away from fixed axis 12 from each position of supporting arm 60.Like this, just might control the mutual end (ends of a plurality of preforms) forward of each supporting arm, by swinging axle 72 caused oscillating motions and from the skew of center of rotation together, supporting arm is radially stretched out at fixed axis 12 by the first cam-operated caused preform.
Preform 1 transmits operation will be in the back in advance with summary.CD-ROM drive motor 30 makes preform 1 by the pre-routing of various work stations is housed.The driving force of motor passes to rotating disk 40 by gear 32,28 and hollow turning cylinder 20.The swinging axle 72 of rotating disk 40 unitary rotation supporting arms 60 supporting ends.The position of the coupling on supporting arm 60 front ends, can with first and second cam followers 106,82 be used for controlled, they are correspondingly along with the operation of the passage of first and second cams 52,54, And affacts on the supporting arm 60.More precisely, supporting arm 60 is to concern according to the position between second cam follower 82 and the swinging axle 72 to swing.It is reciprocating according to the position of first cam follower 106 that straight line moves seat 100, reciprocating motion as supporting arm 60, corresponding with the speed reducing ratio of guiding transmission mechanism 120, it leans on the oscillating motion of swinging axle 72 and the reciprocating resultant motion that straight line moves seat 100 and the transmission mechanism 120 that leads to draw.Preform 1 imports by on first and second cam 52,54 passages that determined by relevant work station.
The layout example of present exposed installation each work station on passage.
In Fig. 6,144, one of 142, one second heating stations of 140, one first heating stations of preform receiving station expansion blowing mould station 146 and one emit station 148, all are arranged on the passage of rotation direction of preform 1.In first and second heating station 142,144, the mobile of supporting arm 60 slowed down, and in order directly to pass to the thermal treatment zone for preform 1 with straight line, supporting arm 60 is stretched out and shunk.In expansion blowing mould station 146, preform is at a stop in predetermined process time.In preform receiving station 140 and emit in the station 148, be to slow down or stop with the corresponding operation of supporting arm 60.In other transmitted the district, supporting arm 60 mobile was to quicken or slow down, and Xun Su And successfully operates on the corresponding work station in order to allow to.
In Fig. 7, for example, the 148a to 148c that stands that emits that three expansion blowing mould station 146a to 146c and heating station 142a to 142c is housed on three positions and is contained in the preform 140a to 140c of receiving station of the last stage of transmitting operation and is located at transmission operation after-stage.In the case, rotating disk 40 and fixed head 10 in order to guarantee the stroke of supporting arm, have enlarged their diameter.Transfer operation is to control like this, that is, preform 1 will be obeyed one of them the operation at expansion blowing mould station 146a to 146c.
The preferred examples of coupling 110 is described referring now to Fig. 8 to 10.
Two clips 150,152 that are contained on coupling 110 lower ends are clamped preform 1 with it.Two clips the 150, the 152nd are set by this way, and it can be rotated in direction respect to one another.For this purpose, two clips 150,152 should have Brake hinge 154,156 mutually.And Brake hinge 154,156 is hinged on the retainer ring 162, and retainer ring and stationary cylinder 160 are whole settings.Brake hinge the 154, the 156th, on the diameter of retainer ring 162 toward each other.
The rotation controling mechanism 170 of two clips 150,152 is to form like this, and the slip ring 172 by stationary cylinder 160 periphery supportings like this, can make ring move axially.On the neighboring of slip ring 172, make gear 172a.In the lower end of slip ring 172, pull bar 174,176 is housed, it is bearing in the opposite position on the slip ring diameter, like this, just can rotate on corresponding top run-on point 174a, 176b.Pull bar 174,176 reaches retainer ring 162 places downwards, and they are hinged on the corresponding clip 150,152.Like this, just can corresponding run-on point 174b, 176b rotate in the bottom.In the case, top run-on point 174a, 176a and bottom run-on point 174b, 176b are selected like this, be imaginary line connect top and bottom run-on point and without Brake hinge 154,156, in this case, clip 150,152 both Ke Zhuan Dong And is drawn close each other, and Zhuan Dong And is separated from each other clip in the case again.Like this, just might prevent that the center of rotation of pull bar 174,176 is in the dead-centre position, clip in the case, and is both rotatable and make it approaching mutually, also rotatable and make clip separately.Thereby, just can get rid of the possibility that pull bar 174,176 rests on the position, dead point, clip 150,152 then rotates according to moving of slip ring.
In order to guarantee the lead of pull bar 174,166, to be kept away from the dead point, the run-on point 174b of bottom, 176b are arranged in the outer position place of imaginary line, its top run-on point 174a, 176a are correspondingly linked Brake hinge 154,156, when the center line of stationary cylinder 160 was the situation of P, clip 150,152 was that it is separated from each other when rotating.
When slip ring 172 was mobile on stationary cylinder 160, pull bar 174,176 was corresponding to top run-on point 174a, 176a and bottom run-on point 174b, 176b rotation.At this moment, round Brake hinge 154,156, the power of rotating connector 150a, 152a just affacts on connector 150a, the 152a.
On the slip ring 172 of sliding motion being given stationary cylinder 160, installed last pushing mechanism as plate 180.The lower surface 172b ， And that plate 180 touches loose collar 172 upwards pushes away slip ring 172, makes slip ring 172 leave retainer ring 162.The spring 184 that slip ring 172 is installed in the ring 182 of band edge forces down.And spring 184 rotates and clip is compress shape when preform 1 separates at clip 150,152, and rotates and when making clip that this connect the neck of nearly And clamping preform 1, be and unclamp shape at clip 150,152.
The ring 182 of band edge be contained in slip ring 172 on the stationary cylinder 160 above.Supporting base 92 is contained in the top of band edge ring 182, and stationary cylinder 160 touches supporting base 92 rotationally.Stationary cylinder 160 is rotating, is in order to rotate the preform 1 in heating station 142 and 144.Rotatory force passes on the slip ring by the gear 172a that is located on the slip ring 172.
In order to connect the reliability of preform 1 and clip 150,152, clip 150,152 is made the neck profile phase adaptation with preform.Like this, clip Zai Zhuan Dong And mutually near the time, can surround neck 2 ， And reliably when the supercharging medium imports, can suppress the expansion (surperficial evagination) of neck 2.For this purpose, it is planar that clip 150,152 is made attached column, and its inner section meets the outside section of preform 1 neck 2.
Usually, preform 1 has a big diameter parts 4 below its neck.By the lower surface 4a of supporting major diameter part 4, clip 150,152 clamping preforms 1 unlikely falling.For this purpose, clip 150,152 should have receiving surface 150b, a 152b mutually, to support the lower surface 4a of major diameter part 4.
By means of the profile of inside and receiving unit 150b, the 152b of clip 150,152, just might transmit preform 1 reliably and can the time not slide for the part operation.In addition, because might be rapidly and control the rotational motion of clip 150,152 exactly, just can promptly contact and unclamp preform 1.Especially, the close rotational motion of clip 150,152 can control to: during beginning, supporting arm 60 touches preform 1; During end, make preform 1 be positioned at clip 150,152 below.Because it also can realize clip 150,152 separately rotational motion rapidly, this just might promptly emit the bottle of finishing, because bottle has passed through blowing mould, and for clamping a new preform 1, clip 150,152 near rotational motion can start at supporting arm 60 for during the part.
