Technical field
The present invention relates to a kind of bracing or strutting arrangement that is used for the preformed member of PETG (polyethyleneterephthalate) bottle, when the neck of PETG bottle by heat treatment so that during its crystallization, described bracing or strutting arrangement supports preformed member and also transmits this preformed member on the direction handling.
Background technology
As known to those skilled in the art, when material such as beverage or cereal were placed in the PETG bottle, the input nozzle of heat can contact or near the neck of bottle.In this case, neck can be out of shape.Therefore, must use neck to be processed into heat-resisting PETG bottle.
When making the PETG bottle, the neck of the preformed member of PETG bottle is heated to suitable temperature preset time section, then cooling.In this case, the particle of neck portion is made neck portion heat-resisting by crystallization.To shown in Figure 4, the preformed member of PETG bottle is inserted in the bracing or strutting arrangement as Fig. 1, makes the supported device of preformed member support.Bracing or strutting arrangement transmits on the processing direction, is rotated by other conveyer simultaneously.Therefore, be inserted in the bracing or strutting arrangement of Fig. 1 to Fig. 4 and under the state by its support at the preformed member of PETG bottle, preformed member is rotated and transmits handling on the direction.Thereby the neck of the outside that is exposed to bracing or strutting arrangement of PETG bottle is at high temperature by heater heat treatment.After this, come cold mold neck branch by cooling heart type chuck.
As shown in Figures 1 to 4, be used for retainer 200 and the elasticity preformed member support unit 300 that traditional bracing or strutting arrangement of the preformed member of PETG bottle comprises matrix 100, has the cylindrical tube shape.Matrix 100 comprises power delivery part 110 that is connected to other conveyer (not shown) and the retainer coupling part 120 that is positioned on the power delivery part 110.The opening 201 that is formed on the lower end of retainer 200 is connected to the retainer coupling part 120 of matrix 100.Elasticity preformed member bracing or strutting arrangement 300 is installed in the matrix 100, and flexibly supports the preformed member P that is inserted in the retainer 200, makes the basic ring Pa of preformed member P and the opening 202 that is formed on the upper end of retainer 200 separate predetermined interval.
The structure of elastic support unit 300 can change as required a little.Fig. 1 to Fig. 4 shows typical elastic support unit.With reference to accompanying drawing, elastic support unit 300 comprises nut 310, preformed member support bar 320 and spring 330.Be installed among the second patchhole 100b of matrix 100 nut 310 reciprocating linear motions.Preformed member support bar 320 comprises preformed member support section 310 and screw threads for fastening part 322, the bottom of preformed member P is fixed and is supported on the preformed member support section 321, and screw threads for fastening part 322 is extended from the bottom of preformed member support section 321 and engaged with nut 310.Spring 330 is installed among the second patchhole 100b of matrix 100 and the nut 310 and be fastened to the preformed member support bar 320 of nut 310 of flexibly setovering on the direction that makes progress.In this case, as shown in Figure 1 to Figure 3, matrix 100 must have the first patchhole 100a and the second patchhole 100b.Screw threads for fastening part 322, the second patchhole 100b that the first patchhole 100a holds preformed member support bar 320 hold nut 310 and spring 330.In this case, label 340 expression is assembled to the block piece to prevent that nut 310 from moving among the second patchhole 100b of matrix 100.Linings to prevent that matrix 100 and nut 310 from directly contacting mutually among the second patchhole 100b that label " 350 " refers to center on nut 310 and be installed in matrix 100.
For example belt (not shown) or sprocket wheel are connected to other conveyer to the power delivery part 110 of matrix 100 by power transfering device.The under shed 201 of retainer 200 by securing member 11 for example screw rod or bolted to the retainer coupling part 120 of matrix 100.In this case, the preformed member P that label " 200a " expression is used for being inserted into retainer 200 is exposed to outside and the hole of cooling preformed member P naturally, and the securing member 11 that label " 200b " represents to be used for fastening retainer is inserted into fastener hole wherein.
Below, will the operation of bracing or strutting arrangement be described.
When the upper opening 202 of preformed member P by retainer 200 was inserted in the retainer 200, the bottom of preformed member P was fixed among the preformed member seat 321a of preformed member support section 321, makes preformed member P be supported on the preformed member support section 321.At this moment, the upper shed 202 of the basic ring Pa of preformed member P and retainer 200 keeps predetermined interval.
In this state, matrix 100 passes through other conveyer rotation and moves on the processing direction, and the feasible preformed member P that is inserted in the retainer 200 rotates with support unit and moves on the processing direction.When preformed member P was transmitted like this, the neck portion on the top of the upper shed that is exposed to retainer 200 202 of preformed member P was by heat treatment at high temperature.
According to prior art, preformed member P is flexibly supported by elasticity preformed member support unit 300, makes the basic ring Pa of preformed member P and the upper shed 202 of retainer 200 separate predetermined interval.Therefore, carry out the heat treatment of preformed member P satisfactorily with a certain temperature.When heating the neck portion of preformed member P by the heater (not shown), the upper opening 202 of retainer 200 and the neck portion of preformed member P are heated together by heater.Yet the part except the upper shed 202 of the retainer 200 that is exposed to heater and heated by heater of retainer 200 is not exposed to heater, and is exposed to atmosphere and is cooled off rapidly.Therefore, retainer 200 is not heated to the temperature (because the heat treatment and the crystallization of the part except that neck portion of preformed member P can cause defective product in the air blast technology of back, so retainer 200 is made by the metal material with high-termal conductivity usually) above predeterminated level.Therefore, when the neck portion of preformed member P during by heat treatment, the hole 200a of the retainer 200 of the part except that neck portion of preformed member P by keeping low temperature cools off naturally.Thereby retainer is not heated the temperature above predeterminated level.
In addition, nut 310 and preformed member support bar 320 are by spring 330 resiliency supported.Therefore, even preformed member P was inserted in the retainer 200 or is inserted into the heart type chuck (not shown) of the heated neck portion that is used for cooling off preformed member P when the preformed member P in being coupled to retainer 200 was extruded in the neck portion that is coupled to preformed member P, spring 330 has also prevented upper shed 202 collisions of basic ring Pa and the retainer 200 of preformed member P, thereby has prevented that basic ring Pa is damaged.
In addition, owing to nut 310 engages in the mode of regulating height with the screw threads for fastening part 322 of preformed member support bar 320, so can support the preformed member of various sizes.
Yet, the problem of the bracing or strutting arrangement of traditional preformed member that is used for the PETG bottle is that preformed member P flexibly supports by elasticity preformed member support unit 300, feasible structure is very complicated, thereby product cost increases the maintenance and repair difficulty.
In addition, rotate in the second patchhole 100b of matrix 100 in order to prevent nut 310, fastener hole 100c is formed in the retainer coupling part 120 of matrix 100, and rotation prevents that recess 310a is formed on the nut 310.After this, nut 310 must for example screw rod or bolt be secured on the matrix 100 by securing member 12.In addition, for the rotation owing to preformed member support bar 320 of the height that prevents preformed member support bar 320 changes, rotation prevents that hole 321b is formed in the preformed member support section 321, and preformed member support bar 320 must by securing member 13 for example screw rod or bolted to retainer 200, thereby manufacturing process complexity.
In addition; the preformed member P that is inserted on the preformed member support section 321 in the upper shed 202 of retainer 200 and that be fixed on elasticity preformed member support unit 300 is not supported on all directions, makes preformed member P to tilt and form with the upper shed 202 of protector 200 to contact.Therefore, by the contact portion generation heat loss between preformed member P and the retainer 200.Like this, when heat treated preformed member P contact at high temperature kept the retainer 200 of low temperature, preformed member P was not owing to the heat loss of contact portion has heat treatment fully, thereby caused faulty goods.
For head it off, the inventor proposed a kind of in Korean Patent No.2004-101849 the disclosed bracing or strutting arrangement that is used for the preformed member of PETG bottle.
This bracing or strutting arrangement is configured and makes circular contact portion be formed on directly or indirectly in the upper shed of retainer, and the basic ring of preformed member directly is fixed on the contact portion of retainer.
Therefore, this bracing or strutting arrangement does not need traditional elasticity preformed member support unit 300, makes that the structure of bracing or strutting arrangement is quite simple, and the cost of bracing or strutting arrangement greatly reduces, and its maintenance and repair are easy.
The part of the basic ring of the fixing and support preformed member of bracing or strutting arrangement is circular, make the direct contact area of retainer and preformed member minimize, thereby the noncrystalline part of the basic ring of preformed member is minimized.Yet, compare with the bracing or strutting arrangement of Fig. 1 to Fig. 4 with elasticity preformed member support unit 300, contact area between retainer and the preformed member increases inevitably, make the neck portion of preformed member more be difficult to crystallization and (consider the loss of heat, the neck portion of preformed member P must be heated the long time period under identical temperature conditions, suppose that perhaps the heat time heating time section is constant, then the heated temperature of the neck portion of preformed member P must increase).

Preferred implementation
Below, describe the present invention with reference to the accompanying drawings in detail.
Fig. 5 and Fig. 6 illustrate view of the present invention.Identical label is used for the parts that the parts with Fig. 1 to Fig. 4 are equal to, and will omit the detailed description to the parts shown in Fig. 1 to Fig. 4.
With reference to Fig. 5 and Fig. 6, the bracing or strutting arrangement that is used for the preformed member of PETG bottle according to the present invention comprises matrix 100, has the retainer 200 and the retainer sleeve 400 of round tube shape.Matrix 100 is provided with power delivery part 110 and retainer coupling part 120.Retainer 200 is configured the retainer coupling part 120 that makes its under shed 201 be connected to matrix 100.Retainer sleeve 400 is installed to the upper shed 202 of retainer 200, supports the basic ring Pa of preformed member P, and is made of to prevent that heat from transmitting between retainer 200 and preformed member P heat-insulating material.
The hear resistance of retainer sleeve 400 must be better than the hear resistance of the preformed member P of PETG bottle.As long as prevent the heat transmission between retainer 200 and the preformed member P, retainer sleeve 400 can use any material.According to this embodiment, retainer sleeve 400 is that polytetrafluoroethylene (PTFE) (its trade mark is Teflon) is made by fluorine resin.PTFE has splendid inertia, hear resistance and good insulating characteristics.In addition, PTFE has non-adhesive and low-friction coefficient.Therefore, when retainer sleeve 400 is made by PTFE, preformed member P frictionally is not inserted in the retainer sleeve 400 or from retainer sleeve 400 glossily to be removed, thereby prevents preformed member P and 400 interference of retainer sleeve, and prevents that preformed member P is scratched or damages.In this respect, to be made by PTFE be preferred to retainer sleeve 400.
In addition, according to this embodiment, retainer sleeve 400 comprises insertion portion 410 and locking step 420.Insertion portion 410 is inserted in the upper shed 202 of retainer 200.Thereby the basic ring Pa of preformed member P is fixed on the locking step 420 and is supported on the locking step 420.Certainly, the shape of retainer sleeve 400 and structure can change as required and differently.For example, retainer sleeve 400 can have simple tubular and not lock step 420.In this case, retainer sleeve 400 must project upwards from the upper shed 202 of retainer 200, makes the basic ring Pa that is coupled to the preformed member P in the retainer sleeve 400 not interfere with the upper shed 202 of retainer 200.
The operation that utilizes bracing or strutting arrangement according to the present invention to make the neck portion crystallization of preformed member will be described below.
At first, the insertion portion 420 of retainer sleeve 400 is inserted in the upper shed 202 of preformed member 200.In this state, preformed member P is inserted in the retainer 200 by retainer sleeve 400, makes the basic ring Pa of preformed member P be fixed on the locking step 410 of retainer sleeve 400.
Then, matrix 100 is mobile on the processing direction by other conveyer, makes the preformed member P that is inserted in the retainer 200 move on the processing direction with bracing or strutting arrangement.Therefore, when preformed member P was transmitted, the neck portion on the top of the upper shed that is exposed to retainer 300 202 of preformed member P was by other heater (not shown) heat treatment.
In this case, even the neck portion of preformed member P is heated by heater, the retainer sleeve of being made by insulating materials 400 has also prevented the heat transmission between preformed member P and the retainer 200.Therefore, the neck portion of preformed member P is heated to suitable temperature rapidly and equably, and does not have thermal loss, makes neck portion crystallization satisfactorily.In fact, the heat loss of the heat loss of the disclosed bracing or strutting arrangement bracing or strutting arrangement extremely more shown in Figure 4 than Fig. 1 is big in korean patent application No.2004-101849, make heating-up temperature or heat time heating time section must increase to make the neck portion crystallization of preformed member P satisfactorily.Yet, under situation, prevented heat transmission between preformed member P and the retainer 200 fully by retainer sleeve 400 according to bracing or strutting arrangement of the present invention.Therefore, reduced heating-up temperature or shortened section heat time heating time, also made the neck portion crystallization of preformed member P satisfactorily even compare with the bracing or strutting arrangement among Fig. 1 to Fig. 4.
Simultaneously, Fig. 7 to Fig. 9 shows bracing or strutting arrangement according to another embodiment of the present invention, and it will be described below.
With reference to Fig. 7 to Fig. 9, in retainer sleeve 400, form the reinforcement patchhole 420a of interior diameter with amplification, on the upper end of the basic ring Pa of preformed member P retainer sleeve 400 fixed thereon, outstanding step 421 is set, outstanding towards the center of retainer sleeve 400 by this way.Bracing or strutting arrangement comprises reinforcement 500, and reinforcement 500 has first insertion portion 510 and second insertion portion 520, and has tubular.First insertion portion 510 is inserted in the upper shed 202 of retainer 200.Second insertion portion 520 is inserted among the reinforcement patchhole 420a of retainer sleeve 400.Retainer sleeve 400 is inserted in the gap that limits between second insertion portion 520 of the upper shed 202 of retainer 200 and reinforcement 500.Preferably, similar in appearance to retainer 200, reinforcement 500 is made by the metal material with high-termal conductivity.Reinforcement 500 is inserted in the upper shed 202 of the retainer 200 that keeps low temperature, makes reinforcement 500 and the retainer 200 the same low temperature that keep.
In this embodiment, when preformed member P was fitted in the retainer sleeve 400, the inner circumferential surface of the outstanding step 421 of retainer sleeve 400 and the inner circumferential surface of reinforcement 500 were exposed towards preformed member P.Therefore, the thickness of the outstanding step 421 by regulating the retainer sleeve can be controlled the heat treatment to the neck portion of preformed member P more accurately.
Being described in detail as follows of bracing or strutting arrangement.
After preformed member P was fitted in the retainer sleeve 400, the neck portion of preformed member P was by heat treatment at high temperature.At this moment, preformed member P is exposed to outside neck portion and directly is heated to high temperature by heater.Like this, when the neck portion that is exposed to the outside of preformed member P directly was heated to high temperature by heater, the part adjacent with the neck portion of preformed member P also was heated to high temperature by the heat conduction, and by crystallization.In this case, unless use reinforcement 500, which in fact can not be controlled partly by the high-temperature heat treatment crystallization.Yet, if the part outside the part that to use reinforcement 500 to cool off rapidly adjacent with the outstanding step 421 of retainer sleeve 400, then preformed member P only carries out the part adjacent with the outstanding step 421 of retainer sleeve 400 by the crystallization of high-temperature heat treatment.Therefore, the thickness of the outstanding step 421 by regulating the retainer sleeve, the high-temperature heat treatment that can control the neck portion of preformed member P more accurately is (along with the thickness of the outstanding step 421 of retainer sleeve increases, increase in part from the basic ring Pa downward direction crystallization of preformed member P, and, reduce) in part from the basic ring Pa downward direction crystallization of preformed member P along with the thickness of the outstanding step 421 of retainer sleeve reduces.
Though disclose the preferred embodiments of the present invention for illustrative purposes, what it will be appreciated by one of skill in the art that is, under the situation that does not break away from the clearly demarcated scope and spirit of the basis that is defined by the claims, can carry out various modifications, interpolation and replacement.
For example, according to embodiments of the invention, the insertion portion 410 of retainer sleeve 400 is coupled in the upper shed 202 of retainer 200, is fastened firmly to upper shed 202 by securing member 14.As required, the insertion portion 410 of retainer sleeve 400 can push in the upper shed 202 of retainer 200 simply, and perhaps the insertion portion 410 of retainer sleeve 400 can be fastened in the upper shed 202 of retainer 200 by the screw type fastening method.Certainly, the insertion portion 410 of retainer sleeve 400 may be fitted on the upper shed 202 of retainer 200.
In addition, retainer 200 can form the diameter that has enough greatly with the preformed member that holds various sizes.Can select the suitable size of retainer sleeve 400 according to the size of relevant preformed member P, making does not only need to replace retainer 200 by replacing retainer sleeve 400, and bracing or strutting arrangement just can hold the preformed member of various sizes.
