The present invention relates to a support structure for container handling machines such as rinsers, filling and capping/seaming machines.
The invention is particularly referred to bottling plants wherein star wheel conveyors and rotating platforms or carousels have to be supported and linked in a structure. In a first prior art, the star wheels are supported on a pre-drilled solid/massive table in such a way that the positions of the star wheels and of the rotating platforms are fixed and predetermined.
The main advantage of said solid/massive table is its own great structural rigidity that assures a sturdy support to the star wheels, thus enabling the latter to rotate at high speed.
On the other hand, said solid/massive table has the important drawback of being custom-made and hence not adaptable to more than one layout of a bottling plant. In particular, since from the manufacturing and pre-drilling steps, it is necessary acknowledged whether the bottling plant envisages a clockwise or a counter-clockwise layout and then manufacturing and pre-drilling the table accordingly. Therefore, after the manufacturing and pre-drilling steps, the layout of the bottling plant is set and cannot be reversed without throwing away the table just created.
According to a second prior art disclosed in document WO 2006/087088, a tubular structure is known. This document shows in-feed and out-feed star wheels arranged to be driven on column-shaped support housings. Each support housing comprises lateral connection interfaces to which a joint end of a connecting bar is detachably attached, to the other joint end being detachably connected to a connection interface of a further support housing or to a machine chassis, such that the star wheel configuration, defining the container transport paths, may be modularly varied.
According to a third prior art disclosed in document WO 2006/087109, a pre-table system for container handling machines is known. In the pre-table, the support housing is fixed to a floor-standing support structure having a tube and/or profile section frame directly or indirectly detachably connected to each other at jointing points, such that the star wheel configurations may be varied. The support housings are arranged in a free-standing manner such that free areas are formed around the support housings.
The second and third prior art disclosed in documents WO 2006/087088 and WO 2006/087109 encompass the following important drawback. The column-shaped support housings (according to the second prior art) or the floor-standing support structure having a tube and/or profile section frame (according to the third prior art) define a whole support structure, or basement, having a very low stiffness. Hence, in order not to over-load the basement, the star wheels cannot rotate at high speed, namely above a limiting-speed.
An aim of the present invention is to avoid the above drawbacks making available a support structure for container handling machines having a great stiffness and simultaneously able to enlarge the number of layouts attainable by the bottling plants.
A further aim of the present invention is to propose a support structure for container handling machines able to reduce the manufacturing costs.
Another aim is to make available a support structure for container handling machines able to contain wires and connections in a protected environment.
This and other aims are fully achieved by the support structure for container handling machines object of the present invention, which is characterized as in the appended claims.
These and other aims will be more detailed in the following description of preferred embodiment, shown as mere example, in the annexed drawings, wherein:
With particular reference to
With special reference to
With particular reference to
In the first embodiment, the first support housings 53 are associated to the handling machines 91 and the second support housings are coupled to floor-standing bearings 5.
As it can be readily appreciate from
Hence, a support structure according to the invention is advantageously able to enlarge the number of layouts attainable by the bottling plant. In particular, such a support structure, once manufactured, is readily adaptable to a clockwise or a counter-clockwise layout by virtue of a simple overturning.
A further advantage is that the support structure has a great stiffness, being made by a single-piece assembled table 2. Hence, the handling machine can work or rotate is at high speed, because such a support structure can absorb high loads induced by the vibrations or rotation of the handling machine.
Advantageously, such a support structure is able to reduce the manufacturing costs, since with few pre-manufactured support structures it is possible attain several layout. In fact, on the basis of desired layout, the support structure can be overturned and then the first and second support housings are connected to respective handling machines or floor-standing bearings. Preferably, the first and second support housings 53, 54 are semi-finished and they are completed as soon as it has been acknowledged the desired layout of the bottling plant.
In the embodiment shown in
Advantageously, such a hollow support structure is able to contain wires and connections in a protected environment.
The hollow structure of the table 2 is preferably obtained by welding said first wall 3 and said second wall 4 to said perimetrical walls 6.
Preferably, said first and second walls 3, 4 have a sloping external surface.
Advantageously, the slope of the external surface prevents the accidental formation of liquid deposit on the wall right below the handling machine.
With specific reference to
Advantageously, perimetrical walls with vertical external surface enhance the simplicity of fastening pipes, tubes etc. to the support structure.
With particular reference to the embodiment shown in
Preferably, electric wires (not illustrated) for controlling and commanding the handling machines are arranged inside said first partition 2a, when the handling machines are installed on said first support housings 53, or inside said second partition 2b, when the handling machines are installed on said second support housings 54, the latter layout correspond to the support structure in overturned configuration with respect to the illustrated embodiments.
With particular reference to
Advantageously, the communication with the external environment enhances the simplicity of assembling the bottling plants and thus provides ergonomics to the support structure. In fact, an arm's operator can enter the table 2 through the support housing and thus comfortably operate on wires, connections etc.
With particular reference to
With specific reference to
Advantageously, such a feature enhances the ergonomic of the support structure because it allows an operator to easily get near the handling machines in order to assemble/repair them.
According to the invention, the two embodiments herewith illustrated can be used to obtain four different layouts, because they can assume overturned positions in the manner described. Therefore, the invention allows a reduction of the manufacturing costs because the number of different support structures that must be produced for a given number of layouts is reduced.
Furthermore, the invention allows a reduction of the stocking costs, because it allows a reduction of the number of different pieces necessary to the obtention of a desired layout.
With special reference to
The second wall 204 is provided with a plurality of second support housings 254 arranged in a mirror-like manner to said first support housings 253 with respect to said plane of reference P. The first and second support housings are alternatively associable to a handling machine (not illustrated, but similar to that schematically shown in
