The grip components making contact, are themselves flexible, or are flexibly-mounted. A device is provided to detach preforms from the conveying path. The support or slide planes are twisted, such that preforms can be guided directly from a hanging position, into a horizontal or perpendicular position (or vice versa). Spacing between the supports or slide planes is variable. The design is further elaborated.

Description

The The invention relates to a device for transporting objects with a profiling, in particular of bottles or preforms with a ring collar, between two slip planes or support means with the help of at least one transport device, of which at least a part of the object frictionally abuts and is supported against receiving elements or pressure rollers.

State of the art

A Variety of objects have to today from one processing station to the next or to the packaging be transported. This applies, for example, to bottles that are on their transport still filled or be labeled. Above all, however, this applies to preforms (preforms), produced in an injection molding machine and then in a blow molding machine to be inflated to a bottle. These preforms have a ring collar, which is essentially for handling the preforms and later Bottles serves. The ring collar is provided near the bottom of the bottle and usually also limits the thread for screwing on a screw cap.

For the transport of bottles are for example from the DE 35 15 353 A1 Hinge chains, flat belts, round profile cords od. Like. Known which engage under the ring collar and thus effect the transport.

In the EP 0 842 875 A1 The ring collar is over or under attacked by a pair of endless cords.

According to today's technology, the preforms produced in the injection molding tool are arranged in complicated and much space-demanding systems and transported to the blow molding. It is new to separate these preforms in a centrifuge-like separator, as he is for example in the PCT / EP2006 / 050682 is described.

task

task The present invention is to provide a suitable device of above type available to ask, with which the objects, especially the preforms, ordered and safe from one to the other next Station can be transported.

Solution of the task

to solution the task leads that the object frictionally adjacent part of the transport device is yielding or yielding is stored.

Wesentlichster Advantage of this yielding support of the objects, that both the possibility transport and congestion. This is for the practical Application of the device of great importance. It also exists also the possibility the generation of a dynamic pressure.

The Container, which are transported, preferably have a hull, a Ring collar and a mouth on, and they are preferably PET bottles or PET preforms. to support and to transport the containers are means of support and transport facilities provided, wherein the support means preferably are fixed in place. The support means can e.g. be formed of plastic or metal strips. The support means but can not only be designed as a bar, but is one any configuration, such as in the manner of a circular one Cross-section band provided possible.

The at least one transport device is preferably for the main energy input into the containers to the forward movement Responsible in the transport direction. The support means and the transport device preferably engage below or above the ring collar. An engaging the ring collar engaging the support means or transport device is just as conceivable as one with a slight distance performed to the ring collar Engagement.

The at least one transport device is preferably designed as an endlessly circulating strand, on which spring elements are mounted. By interaction of the spring elements with a sub support means or spring elements of other transport devices results in a clamping detection of the container in the region of the annular collar.

According to one preferred embodiment of the invention are the support means immovable and the transport device in the transport direction movable attached, more preferably, two support means and two transport devices available. Preferably, the containers are suspended so transported that the support means parallel tangential engage below the ring collar, while the both transport devices tangentially parallel above the annular collar are attached. However, it is also within the scope of the invention that three means of support are present, which the container keep in a certain position, while a transport device for the forward movement ensures in the transport direction.

Farther Is it possible, altogether only three support or to provide transport facilities. Either two support and one transport device or two transport devices and a means of support be provided. With four available attack possibilities over or below the ring collar of the preform and left and right The same remains with the use of three means of support transport facilities clear an attack site, and it is completely irrelevant whether the vacancy is left, right, up or down.

To a particularly preferred embodiment of the invention is a Part of the transport device designed as an endless circulating chain, the chain being at least a chain strand, receiving elements and spring elements. A return of the chain is preferably carried out parallel to a ring collar plane. The chain has at regular intervals receiving elements on which spring elements can be attached. The spring elements can thereby be designed so that per receiving element, a spring element or that several receiving elements are required per spring element. The receiving elements are preferably rollers with incorporated therein Grooves in which the spring elements are known to be guided. Preferably Therefore, the spring elements are made of wire, in the grooves guided the receiving elements is or stops. However, the receiving elements can also bolts or other spring attachment options be. In addition, it is conceivable that the spring elements directly on the attached to the revolving chain. Preferably, two receiving elements used for fastening a spring element, wherein the distances of the Receiving elements that absorb spring elements, larger, smaller or may be the same to the distances the next Receiving elements.

at the embodiment, in which the spring element is made of wire and on two receiving elements is fixed, a preferred attachment looks like that the beginning and the end of the wire are located on a receiving element, while the other receiving element is looped by the wire, preferably one and a half. The one receiving element is preferably of the wire surrounded so that it forms a C-shape, the distance of the Thighs of the C-shape bigger is the diameter of the one receiving element. In this way Is it possible, that the spring element moves relative to the receiving element to container to be able to grip in a pinch.

According to one preferred embodiment of the invention are two as endless circulating chains trained transport left and right parallel to the transport direction, the container above the annular collar grip it. In this arrangement, the chain strands with whose receiving elements and spring elements mirrored at the by the midpoints of transported in a row in the transport direction container arranged extending level. The reflection has the advantage that the spring elements the container can capture optimally. In their non-clamping state are two opposite ones C-shaped Areas of spring elements spaced from each other so that the Ring collar diameter larger is the distance between these two spring element areas. this has the advantage that optimal clamping of the container can be achieved. Be the containers between two C-shaped ones Clamped areas of the spring elements, so move the the Container at Ring collar touching Thighs of the C-shaped Elements in the direction of the centers of the receiving elements. Thereby, that the spring elements wrap around a receiving element is a otherwise attachment not necessary.

At the Transport of the containers through the device are the annular collars in a ring collar level, preferably perpendicular to the plane through the centers of the in series transported container. According to a preferred embodiment of the invention, the spring elements and the supportive means arranged so that they are parallel to the annular collar level. An angular arrangement of the support means and / or the transport means but is also conceivable, so that e.g. an arrangement of the spring elements in terms of the ring collar level at an angle between 0 and 90 degrees conceivable is.

Around the chain attached to the receiving elements or the spring elements are to lead optimally according to a preferred embodiment of the invention guides provided in which the chain strands can run. The exact guidance The circulating transport facilities has the advantage that too the receiving elements or the spring elements are guided exactly, which in turn leads to that the holding force between two spring elements exactly defined can be. Preferably, the spring elements are designed so that they can be adjusted, so that the holding force with which the container captures the ring collar can be is adjustable. The spring force is best adjusted so that the spring elements occurring at back pressure of the container anyway continue to run, the container So "slip through".

The guides preferably have grooves in which the chain strands are guided can. The guides are preferably parallel to the transport direction.

In a further embodiment The invention should at least a part of the transport device, which the object frictionally abut, bear against pressure rollers and these pressure rollers yielding be stored. This will ensure a safe transport of the preforms guaranteed. In one embodiment the invention are the pressure rollers on spring tongues, leaf springs, spring clip or the like. stored, which are biased. In a further embodiment of the invention the pressure rollers be arranged on a bearing block, which then turn over a spring is supported against a wall. So that this spring does not break out laterally, it preferably wraps around a bolt, over the bearing block is inserted into the wall.

In an embodiment of the invention the object to be transported on both sides endless belt, preferably Endlosrundriemen be assigned, between which then to transporting object is trapped. By the choice of endless round belts in cross-section will not change the points of attack at the objects instead, indifferent in which position the preforms are transported.

These Endless belts wrap around spaced pulleys, the are preferably tilted, so that by changing the position of the pulleys Not only hanging preforms, but also transported horizontally or even vertically can be as desired. Here additionally helps a hold-down, on which the preforms abut or abut. This means that the preforms can be transported in any position and unclocked what in the previously known devices was not possible. For example, it was so far no transport and back pressure generation of preforms from bottom to top possible. With the inventive Device is this feasible.

Of course, too the slip planes or support means the desired Transport track to be adapted. This is any guide the preforms possible. This has the consequence that the spatial Alignment of preforms to an inlet on a glass machine can be adapted to different manufacturers.

specially during the transport of preforms but also of bottles the need for the transport path to extend in one plane. runs However, the transport path rising or falling and goes through there different slopes, so there are positive and negative slope areas, in which the distance between the center axes of successive objects reduced or extended. If the distance decreases, so soft the successive items need more Place and can to wedge. Further, they rub against each other.

Around to prevent this disadvantage, is according to the present invention in one embodiment the possibility opened, that a deflecting element in the range of negative slope in the transport path of the objects is inserted so that they slide along a sliding surface and after be directed outside. This will reduce the distance between the center axes of successive preforms raised again.

Conceivable is also that the slip planes on which the collars of the Slide preforms along, in different areas in different Layers run. This results in a tilting of the preforms, so These are also deflected laterally and the distance of their Central axes raised again becomes.

Conceivable is also the arrangement of differently inclined slip planes, which can also be offset at different heights. Here are many possibilities conceivable and should be encompassed by the present invention.

Just the possibility, which the present invention by the different arrangement which offers glide levels leaves For example, the problem of a negative sheet does not arise at all. The preforms can be transported in any position of their central axes, so the desired one Distance of the center axes by change the position of the preforms in the room can be accommodated.

One Another idea of the present invention relates above all insisting that the distance between the slideways be changeable is. For this purpose, the slideways are part of a housing which is preferred from two housing shells consists. The two housing shells form a slot in the region of the slideways, with marginal edges a desired one Keep distance from each other. The margins take in position of use between them the preforms.

Around now change this distance to be able to should the two housing shells be slidable into each other, including, for example, two leg strips overlap the housing shells and so overlapping can be connected to each other.

1 shows a device 1 for transporting preforms 2 for the production of plastic bottles. The preforms 2 are brought into series by a preform sorting, not shown here, and thus into the device 1 introduced and transported to a stretch blow molding machine, not shown here. The device 1 has two supportive means 4 on which the preforms 2 below the ring collar 3 support. In addition, the device 1 transport equipment 5 on which the preforms 2 or, as in 12 shown bottles 2.1 left and right above the ring collar 3 support. The transport facilities 5 consist in each case of a chain strand 21 , several recording elements 7 . 7 ' and several spring elements 6 , The chain strand 21 is designed as a link chain similar to a bicycle chain. At some joints of the chain links of the chain strand 21 are at the connecting pin down towards receiving elements 7 . 7 ' appropriate. Two receiving elements each 7 and 7 ' are of a spring element 6 entwined. The spring elements 6 are attached so that a resilient action towards the inside in the direction of the preforms 2 arises.

2 shows the device 1 in the bottom view, wherein it can be seen that the preforms 2 be transported in a row, passing through a line through the midpoints 8th of the preforms 2 is defined. The transport takes place in the transport direction T. The structure of the device 1 is mirror-symmetrical to a plane passing through the midpoints 8th and through the longitudinal axes of the preforms 2 goes. Again, the two guides 9 to see where the chain strands 21 be guided. The chains are constructed as link chains in the form of bicycle chains. At the chain strands 21 are the receptacles 7 and 7 ' attached. In turn, these are the spring elements 6 appropriate.

Like a spring element 6 around two receiving elements 7 . 7 ' winds, is best in 2 top right through the dashed spring element 6 shown. The chain beginning 6 ' is about the receiving element 7 C-shaped bent, wherein the diameter of the receiving element 7 is smaller than the distance between the two legs of the C-shape. That is, the lower leg of the C-shape of the spring element 6 in the transport path of the preforms 2 stands. The spring element 6 will continue to the receiving element 7 ' which it wraps around one and a half times, then again in the direction of the receiving element 7 to be returned. The end of the spring element 6 '' is located at the preforms 2 facing side of the receiving element 7 ,

By the plant of the beginning of the spring element 6 ' and the end of the spring element 6 '' on the receiving element 7 and by the wrap of the receiving element 7 ' a spring force is generated, which with a vertical component to the transport direction T, the preforms 2 resiliently clamped. Are there no preforms 2 between two opposing spring elements 6 , so they have a distance A from each other, which is less than the diameter of the mouth region of the preforms 2 , Are there preforms 2 between two opposing spring elements 6 so becomes the C-shaped part of the element 6 in the direction of X towards the center 17 the receiving elements 7 emotional.

3 shows a section through a device 1 , Again, this is a preform 2 see below his ring collar 3 left and right each of a support means 4 is supported. Above the ring collar 3 engages left and right each a spring element 6 at. The spring elements 6 , which in turn are parallel to the annular collar plane N, are on the receiving elements 7 ' attached. Here is clearly the wrap of the spring element 6 around the receiving element 7 ' to see. The receiving element 7 ' is on the chain strand 21 attached. The endlessly circulating chain strand 21 will be in the lead in the lead 9 located groove 10 guided. In this way, a stabilization of the transport device takes place 5 ,

In 4 is basically the same device 1 as in 3 shown, but with the difference that a supportive 4 and a transport device 5 have an angle γ to the annular collar plane N, which is greater than zero degrees. However, the angle γ can only at the transport device 5 or only with the support means 4 issue.

Another embodiment of an inventive device for transporting Vor Formlingen shows according to 6 and 7 a housing 22 on, which consists of two housing shells 23.1 and 23.2 is formed. The housing shells 23.1 and 23.2 are interleaved, so that a distance a from marginal edges 24.1 and 24.2 that have a slot 25 can be changed between themselves. For this purpose, the two housing shells overlap 23.1 and 23.2 with her upper thighs 26.1 and 26.2 and are in this overlap area by fasteners not shown in detail, which in 5 shown slots 27 enforce, connected.

In the slot 25 slide the preforms 2 , taking with the ring collar 3 sliding planes 32.1 . 32.2 laterally adjacent to the marginal edges 24.1 and 24.2 rest.

The transport of the preforms 2 along the slot 25 in the case 22 serve two double-sided endless belts 29.1 and 29.2 , the pulleys 30.1 and 30.2 wrap around and in plastic rails 42 to run. Here, the endless belts nestle 29.1 and 29.2 above the ring collar 3 close to the neck of the preforms 2 and take the preforms 2 frictionally engaged with. So that the preforms 2 can not move upwards, additionally serves a rail 31 as a downholder.

In 9 are the two glide planes 32.1 and 32.2 indicated on which the ring collar 3 along slides. But dashed are other different positions of use of the pulleys 30.1 respectively. 30.2 indicated so that it becomes apparent that the corresponding endless belts 29.1 and 29.2 the preform 2 in each desired position attack and can transport, depending on which situation is constructive to prefer. This depends above all on whether a hanging transport of the preforms, a horizontal or even a vertical transport is desired. The last two mentioned transport options are in 12 indicated. In the 10 and 11 is also shown that by the appropriate guidance of the slip planes 32.1 and 32.2 Alignment of the preforms from a horizontal position in a suspended position is possible without difficulty. The same is of course also true for aligning the preforms from a hanging to a horizontal position and from there even in a vertical position. All this is possible by the transport devices according to the invention.

According to the 7 and 8th grab the two endless belts 29.1 and 29.2 the preforms 2 from one side each so that the preforms 2 during their transport through the slot 25 to be moved. So the endless belts 29.1 and 29.2 in close, that means in frictional contact with the preforms 2 arrive, are lateral pressure rollers 33.1 and 33.2 provided the endless belts 29.1 and 29.2 resilient against the neck of the preform 2 above the ring collar 3 to press. These pressure rollers 33.1 and 33.2 run with the endless belts 29.1 and 29.2 , They turn around a rotation axis 34.1 and 34.2 , in each case on a spring tongue 35.1 and 35.2 hang, which is biased and the pressure rollers 33.1 and 33.2 against the endless belt 29.1 and 29.2 suppressed.

In a further embodiment of an inventive device for the transport of preforms 2 according to the 13 and 14 are the pressure rollers 33.1 and 33.2 each on a storage block 36.1 and 36.2 arranged, each bearing block 36.1 and 36.2 over a bolt 37.1 and 37.2 on a wall 38.1 and 38.2 is held. Against this wall 38.1 and 38.2 each storage block is supported 36.1 respectively. 36.2 over a coil spring 39 off which the bolt 37.1 and 37.2 wraps. This coil spring 39 is also biased so that the pressure rollers 33.1 and 33.2 the endless belt 29.1 and 29.2 against the preform 2 to press.

According to the invention, it is in the device for the transport of preforms 2 also be possible to go through with the preforms a curvy transport path. For example, if the preforms are arranged hanging, as in 15 and passing through different pitches of the transport path, positive and negative pitch areas are traversed, that is, in the positive pitch areas, center axes of adjacent preforms are spaced more while adjacent preforms are spaced into the negative pitch area in the ring collar 28 following area are pressed against each other and dodge each other, so that the preforms are no longer guided in a plane and jam. This can be done according to 16 and 17 once avoided by being in the area of the slot 25 a deflecting element 40 with a rounded sliding surface 41 is used. In the area of this sliding surface 41 become the preforms 2 deflected so that they have more space in the negative bow area available and the disadvantage of a negative slope is lifted.

Another possibility according to the 18 and 19 is that the slip planes 32.1 and 32.2 pass through different heights in sections, so that the preforms 2 be tilted outwards in this area.

Furthermore, according to 20 also the possibility of the glide plane 32.1 and 32.2 inclined to arrange at different heights, so also the preforms 2 be tipped to the outside.
