Summary of the invention
The object of the present invention is to provide a kind of above-mentioned the sort of appropriate device, arrange that by this device object, especially preformed mould base, and be transported to therefrom on the nearest platform reliably.
For achieving this end, a part of feedway that is adjacent to this object is soft or flexibly supported frictional connection.Flexibly keep the major advantage of object to be, the possibility that has conveying and pile up.It is in order in fact to use very important device.In addition, also has the possibility that produces dynamic head.
The container that is transferred preferably has framework, annular lip and opening, and they are preferably the PET-bottle or the PET-preformed is moulded base.Bracing or strutting arrangement and feedway are set, and to support and transport box, wherein bracing or strutting arrangement is preferably the position and is fixed regularly.Bracing or strutting arrangement for example forms by plastics or laths of metal.But bracing or strutting arrangement not only forms lath, and can be any device, as for example possible in being provided with the band of circular cross section.
This at least one feedway is preferably suitable gross energy and enters into container to travel forward along throughput direction.Bracing or strutting arrangement and feedway preferably are engaged in bottom or the top of annular lip.Contact interior combination annular lip, bracing or strutting arrangement or feedway can be considered just the same, as an interior combination of leading to annular lip with less distance.
This at least one feedway preferably form circulation around the reversion section, spring installation is fixed in this reversion section.The co-operation of the spring installation by spring installation and bracing or strutting arrangement or another feedway is clamped in container in the zone of annular lip.
According to a preferred arrangements of the present invention, bracing or strutting arrangement can not be mounted with moving, and feedway can be mounted along throughput direction with moving, further preferably, has two bracing or strutting arrangements and two feedways.Preferably, these containers are transferred so hangingly, so that two feedways were installed on the top of annular lip abreast along tangential direction during, bracing or strutting arrangement was abreast along the bottom that tangentially cooperates annular lip.But following these also fall within the scope of the present invention, and namely have three bracing or strutting arrangements, and for during proal along throughput direction, these three bracing or strutting arrangements remain on container on the preposition at feedway.
In addition, below these are possible, namely generally speaking, only arrange three and support or feedway.Therefore, two bracing or strutting arrangements and a feedway are set, two feedways and a bracing or strutting arrangement perhaps are set.Four operational, be combined in preformed and mould in the annular lip top or the possibility on bottom and its left side and the right part of base, binding site is kept freely, if free position is left part, right part, top or bottom, it is fully inessential so.
Arrange according to a particularly preferred the present invention, a part of feedway form circulation around chain, chain is formed by chain circuit, receiving member and a spring installation at least.Be preferably and be parallel to the recirculation that the annular lip plane earth is realized chain.Chain has receiving member in certain distance, spring installation is fixed in this receiving member.Therefore spring installation can so form, and namely each receiving member needs a spring installation, and perhaps each spring installation needs a plurality of receiving members.Receiving member is preferably has the roller that is installed on groove wherein, and spring installation is directed in this groove.Preferably, spring installation is made by metal filament, and this metal filament is directed or obtains supporting in the groove of receiving member.But receiving member can be fixedly possibility of bolt or other spring.In addition, can consider, spring installation directly be fixed on around chain on.Preferably, two receiving members are used for fixing spring installation, wherein receive spring installation receiving member distance greater than, be less than or equal to the distance of nearest receiving member.
Make and be fixed on by metal in two embodiments on the receiving member at spring installation, so show preferred fixing, namely during another receiving member that is formed by metal filament was wound, is preferably winding 1.5 circles, start portion wiry and closing position were on receiving member.Metal filament is preferably and so surrounds this receiving member, and namely it forms C shape, and wherein the distance of the supporting leg of C shape is greater than the diameter of this receiving member.In this method, thereby spring installation is fine with respect to the receiving member grip containers of moving.
According to a preferred arrangements of the present invention, two form Cyclic Rings around the feedway of chain be parallel to throughput direction about being arranged to, it is clamped in container on the top of annular lip.In this layout, the chain circuit with receiving member and spring installation is arranged in the plane of the midway location that extends through the container of carrying successively along throughput direction symmetrically.This symmetry has such advantage, and namely spring installation maintains container best.Do not having in the situation about clamping, two opposed C shape zones so are spaced from each other by spring installation, and namely the annular lip diameter is greater than the distance in two spring installation zones.It has such advantage, i.e. grip containers best.If container is clamped between two C shape zones of spring installation, container contact supporting leg annular lip, C shaped element part is moved along the direction of the midway location of receiving member.By making spring installation twine receiving member, do not need the fixing of other.
When coming transport box by this device, annular lip is positioned at the annular lip plane, and this plane is preferably the plane perpendicular to the midway location of the container that is transferred by order.According to a preferred arrangements of the present invention, spring installation and bracing or strutting arrangement arrange that so namely they are arranged to be parallel to the annular lip plane.Therefore but the angled layout of bracing or strutting arrangement and/or feedway also is admissible, for example can consider that spring installation arranges to the angles of 90 degree with 0 degree with respect to the annular lip plane.
In order to guide best receiving member or spring installation to be fixed in wherein chain, therefore according to a preferred arrangements of the present invention, be provided with guiding piece, the chain circuit can turn round in this guiding piece.Accurately guided rings around feedway have such advantage, namely receiving member or spring installation accurately are directed, this causes again can accurately limiting confining force between two spring installations.Preferably, spring installation so is formed, and namely they can be adjusted, and the confining force that therefore container is remained on the annular lip is adjustable.Spring force preferably so is adjusted, i.e. spring installation still further running when producing the dynamic head of container, and namely this container also " slips over ".
These guiding pieces preferably have groove, and the chain circuit can be directed in this groove.These guiding pieces preferably are arranged to be parallel to throughput direction.
At least a portion feedway that is adjacent in another embodiment of the present invention object is supported on the pressure roller and flexibly supports pressure roller frictional connection.Therefore, can guarantee to carry reliably preformed to mould base.In one embodiment of the invention, pressure roller is supported on biased spring leaf, steel spring, saddle clamp or the allied equipment.In another embodiment of the present invention, pressure roller is disposed on the supporting mass, this supporting mass again by spring supporting on wall.By making spring not have sidepiece to fracture, it preferably twines bolt, and wherein supporting mass is inserted in the wall by this bolt.
In one embodiment of the invention, endless belt, be preferably the circulation circular belt have the object that will carry in both sides, the object that be transferred is clamped between the belt.Be the endless belt of circle by selecting cross-sectional plane, so that the point of action on the object does not change, preformed is moulded base and is transported on this position unimportantly.
Endless belt twines the guiding roller leave layout, and this guiding roller is preferably and can tilts, and therefore respectively according to demand, makes preformed mould base not only hangingly but also on even keel or even vertically be transferred by the position that changes guiding roller.Here, anchor clamps are still still useful, and preformed is moulded base and fixed or abut against on these anchor clamps.That is, preformed is moulded base and can be transported on each any position and can be transferred non-contiguously, and this is impossible realize in disclosed device up to this point.For example, up to now, do not have preformed to mould base conveying and dynamic head from bottom to top and produce.By device of the present invention, can realize it.
Certainly, slip plane or bracing or strutting arrangement must be suitable for desirable transfer passage.In this method, each any guiding piece that preformed is moulded base is fine.It causes, and the pressure that the space orientation that can make preformed mould base is suitable for different makers adds the entrance of machine.
Especially when carrying preformed to mould base, still also can be when carrying bottle, have such essentiality, namely transfer passage in one plane extends.But, the ground or the ground that descends extends and by different slopes, it has produced the sloped region of positive and negative so if transfer passage rises, in the sloped region of this positive and negative, medial axis reduces or has increased from the distance of the object of mutually following.If this distance reduces, the object of so mutually following has been offset, and needs many spaces, and can be reduced.In addition, their phase mutual friction.
In order to prevent this shortcoming, therefore such possibility is disclosed in one embodiment according to the present invention, namely deflection piece is inserted in the transfer passage of object in the zone on negative slope, thus they on slidingsurface along sliding and outwards being handled.Therefore, this minimizing distance between the medial axis of the object of mutually following has further increased.
Below these also are admissible, namely the preformed annular lip of moulding base is extended in the individual region of slip plane in Different Plane of sliding thereon.Therefore can realize that preformed moulds the inclination of base, therefore also be deflected and its distance of medial axis further is enhanced at sidepiece.
It is also conceivable that the layout of different suitable slip planes, this slip plane can extend at differing heights with moving.Here, many possibilities also are admissible and the present invention also comprises these possibilities.
Especially the present invention arranges that by the difference of slip plane this possibility that provides will not at first produce for example problem of hogging bending.Preformed is moulded base and can be transported on its any position of medial axis, therefore moulds the needs that the position of base in this space adapts to the ideal distance of medial axis by changing preformed.
Another scheme of the present invention at first relate to following these, namely the distance of guide rail can change mutually.For this purpose, guide rail is the part of housing, and this housing is preferably by two cup-shaped one-tenth of housing.Two housing cups form groove in guide rail area, incline keeps desirable distance each other.Incline is on preformed is moulded use location between the base.
In order to change this distance, therefore two housing cups can be moved mutually now, therefore for example two of housing cup bottom bands of trouser legs stacked and so interconnect stackedly.
