Definitions
- the present invention relates to a block-support head for a corking machine.
- the head in question is intended to be used advantageously in the bottling industry for compressing stoppers made of cork or synthetic material until they have a size slightly smaller than the mouth of the neck of the bottle to be corked.
- conventional corking machines envisage the use of a plurality of corking heads mounted rotatably in the form of carousel about a fixed vertical shaft on which a pusher cam is concentrically keyed in order to impart the necessary movement to the components of the head which perform corking.

- each head is composed of two block-supporting slides, one of which is movable, being mechanically connected to a cam by means of a guide and a counter-guide, and the other fixed, being fastened on the housing structure of the machine by means of key-type retaining means.
- the same housing structure of the machine allows guiding of the to-and-fro movement of the movable slide actuated by the cam with respect to the fixed slide.
- the gripping means are generally formed by two pairs of blocks, each associated with a respective slide, by means of which they define with their form a cavity for receiving the stopper.
- the blocks vary their arrangement and, therewith, the size of the opening for receiving the stopper.

- the movable blocks are mounted on respective slides by means of guides with a specific shape, generally dovetail shape, able to keep the said slides perfectly positioned along the whole of their travel path during the to-and-fro movement.
- the four blocks (2+2) are made of special stainless steel, which is tempered and ground to a degree of precision of hundredths.
- Machining with a small tolerance may result in seizing of the blocks, whereas too large a tolerance is the cause of malfunctioning due to insertion, in the free space, of agglomerations of dust or small pieces of stopper or other material such as a lubricating product, which may cause scoring or pricking of the stopper, adversely affecting correct corking.
- the presence of the guide poses a certain degree of difficulty with regard to disassembly of the head and rapid extraction of the blocks, for example necessary in order to perform maintenance operations, cleaning or sterilisation operations or replacement of the blocks in order to modify the corking procedure.
- a second drawback arises from the fact that, with time, after a certain number of hours of operation, the blocks start to wear and therefore need to be replaced.

Abstract
Description
- The present invention relates to a block-support head for a corking machine.
- More particularly, the head in question is intended to be used advantageously in the bottling industry for compressing stoppers made of cork or synthetic material until they have a size slightly smaller than the mouth of the neck of the bottle to be corked.
- At present, as is known, conventional corking machines envisage the use of a plurality of corking heads mounted rotatably in the form of carousel about a fixed vertical shaft on which a pusher cam is concentrically keyed in order to impart the necessary movement to the components of the head which perform corking.
- Each head comprises gripping members able to compress the stoppers supplied from a suitable loading hopper until they have a size suitable to allow them to be inserted inside the neck of the bottles under the vertical thrust of pusher elements.
- As is known, each head is composed of two block-supporting slides, one of which is movable, being mechanically connected to a cam by means of a guide and a counter-guide, and the other fixed, being fastened on the housing structure of the machine by means of key-type retaining means.
- The same housing structure of the machine allows guiding of the to-and-fro movement of the movable slide actuated by the cam with respect to the fixed slide.
- In greater detail, in accordance with the technology known hitherto, the gripping means are generally formed by two pairs of blocks, each associated with a respective slide, by means of which they define with their form a cavity for receiving the stopper.
- As a result of the to-and-fro movement of the movable slide, the blocks vary their arrangement and, therewith, the size of the opening for receiving the stopper. In particular, the blocks may assume an open configuration, where the opening has a cross-section which is sufficiently wide to receive a stopper inside it, and a closed configuration where the receiving opening is narrowed so as to define a cross-section slightly smaller than the mouth of the bottle neck so as to allow the compressed stopper to be inserted inside it.
- Conventionally the movable blocks are mounted on respective slides by means of guides with a specific shape, generally dovetail shape, able to keep the said slides perfectly positioned along the whole of their travel path during the to-and-fro movement.
- The block-support heads known hitherto of the type described briefly above have proved to have certain drawbacks.
- A first drawback arises from the fact that manufacture of blocks with a shaped part for engagement in the dovetail guide requires very precise mechanical machining of the said blocks, which is somewhat difficult to achieve and therefore, ultimately, costly. Normally the four blocks (2+2) are made of special stainless steel, which is tempered and ground to a degree of precision of hundredths.
- Machining with a small tolerance may result in seizing of the blocks, whereas too large a tolerance is the cause of malfunctioning due to insertion, in the free space, of agglomerations of dust or small pieces of stopper or other material such as a lubricating product, which may cause scoring or pricking of the stopper, adversely affecting correct corking.
- Moreover, excessive or poorly distributed lubrication of the blocks may result in over-lubrication of the stoppers and therefore also prevent correct execution of the corking operations.
- The presence of the guide poses a certain degree of difficulty with regard to disassembly of the head and rapid extraction of the blocks, for example necessary in order to perform maintenance operations, cleaning or sterilisation operations or replacement of the blocks in order to modify the corking procedure.
- A second drawback arises from the fact that, with time, after a certain number of hours of operation, the blocks start to wear and therefore need to be replaced. Before being replaced, they may also result in malfunctions of the type mentioned above which may negatively affect the quality or the efficiency of the corking operations.
- Obviously, the fairly frequent replacement of the blocks represents a major operational drawback of the current block-support heads and results in an overall increase in the costs of the corking process.
- The main object the present invention is therefore that of overcoming the drawbacks associated with the solutions of the known type mentioned above, by providing a block-support head for a corking machine, which is constructionally simple and inexpensive to manufacture and operationally entirely reliable.
- Another object of the present invention is that of providing a block-support head, the components of which, such as the blocks, can be easily manufactured by means of simple mechanical machining processes.
- A further object of the present invention is that of providing a block-support head which requires a limited amount of maintenance.
- A further object of the present invention is that of providing a block-support head, the components of which, such as the blocks, do not give rise, even after numerous hours of operation, to significant variations in the quality or the efficiency of the corking operations.
- These and other objects are all achieved by the block-support head in question, which is intended to be mounted on a housing structure of a corking machine and which comprises a fixed slide substantially integral with the housing structure and provided with a first pair of blocks; a movable slide which can be actuated with a relative to-and-fro movement with respect to the fixed slide and is provided with a second pair of blocks. The first pair of blocks and the second pair of blocks define a receiving opening for a stopper and are able to vary their arrangement during the to-and-fro movement, between an open configuration, where the receiving opening is able to receive a stopper inside it, and a closed configuration, where the receiving opening compresses the abovementioned stopper.
- According to the invention, the block-support head is characterized in that each pair of blocks comprises at least one movable block, able to slide on the respective slide over a first travel path, and at least one compression block, which is associated with one of the slides and acts with pressure against a first sliding surface of the movable block associated with the other slide. First resiliently yielding means are envisaged for pushing the compression block against the movable block.
- The technical characteristics of the invention, in accordance with the abovementioned objects, may be determined from the contents of the claims indicated below, and the advantages thereof will emerge more clearly from the detailed description which follows, provided with reference to the accompanying drawings, which show a purely exemplary and non-limiting example of embodiment in which:
- Figure 1 shows schematically a top plan view of a first example of embodiment of the block-support head according to the present invention with the blocks in a partially open configuration and with some parts removed so that other parts are more clearly visible;

- Figure 4 shows a cross-sectional view of the block-support head according to Figure 2 along the line IV-IV in Figure 2;
- Figures 5 and 6 show enlarged details of the block-support head according to the preceding figures, consisting of a perspective view of a movable block and compression block;
- Figure 7 shows an enlarged detail of the preceding figures, relating to a self-lubricating plate;
- Figure 8 shows in schematic form a bottom perspective view of a second example of embodiment of the block-support head according to the present invention;
- Figure 9 shows a side view of the block-support head according to Fig. 8;
- Figure 10 shows a bottom plan view of the block-support head according to Figure 8, inserted inside a housing structure of a corking machine, with the blocks in the open configuration;
- Figure 11 shows an overall view of several heads operationally associated with each other inside a housing structure of a corking machine.
- In accordance with the figures in the accompanying drawings, the block-support head forming the subject of the present invention is denoted in its entirety by 1.
- It is intended to be mounted on a corking machine, in particular of the rotating carousel type provided with a housing structure 2 having, arranged inside it, several block-support heads 1 which are spaced from each other circumferentially (see Figure 11).
- The housing structure 2, which has been shown only partially in broken lines in Figure 10, allows the heads 1 to be supported rotatably about the shaft of the rotating carousel of the corking machine, absorbing the compressive forces exerted by the heads 1 during the corking operations.
- Each head 1 is suitable for use in association with stoppers made of any material (cork, synthetic material, as well as "technical stoppers" made of cork composites, both of the flat and sparkling wine type).
- The head 1 is essentially composed of a
fixed slide 3 which is removably mounted in the housing structure 2 by means of key-type retaining means 4 of the type known per se and amovable slide 5 which can be actuated with a relative to-and-fro movement in a radial direction R with respect to thefixed slide 3, by suitable actuating means 6. - The latter, which are only partly shown in the accompanying figures, advantageously comprise a
wheel 7, which is mounted on themovable slide 5 and is free to rotate about a vertical axis Z perpendicular with respect to the radial direction R and capable of imparting the to-and-fro movement to themovable slide 5 as a result of interaction with acam 70. - Suitable guide means allow the
movable slide 5 to slide with respect to thefixed slide 3 inside the seat formed in the housing structure 2. These means may for example comprise, in accordance with a possible constructional solution, twoplates 50 fixed laterally to themovable slide 5. - Two pairs of blocks are also envisaged, i.e. a
first pair 8, mechanically and operationally associated with thefixed slide 3, and asecond pair 9, mechanically and operationally associated with themovable slide 5, said pairs defining a receivingopening 10 inside which a stopper (not shown in the accompanying figures) is intended to be inserted. - Owing to the effect of the to-and-fro movement imparted to the
movable slide 5, the blocks vary their arrangement between anopen configuration 11, shown in Figure 1 and Figure 10, where a stopper may be conveyed inside the receivingopening 10, and a closedconfiguration 12, shown in Figure 2, where the side walls of thereceiving opening 10 compress the stopper to a size slightly smaller than the mouth of a bottle neck, so as to allow suitable pusher means to push the stopper inside the said neck. - According to the invention, the block-support head 1 is characterized in that both the pairs of blocks comprise a
movable block 13, able to slide on its associatedslide compression block 14. Each compression block associated with aslide front surface 15 against a first slidingsurface 16 of themovable block 13 associated with theother slide means 17, in particular consisting of an ordinary first spring (see Figs. 3 and 10). - The first travel path A has a length such as to allow the blocks to be displaced between the
open configuration 11 and the closedconfiguration 12. - In order to allow the return of the
movable blocks 13 into theopen configuration 11, second resiliently yieldingmeans 18 are provided, said means consisting for example of a second spring and acting so as to compress themovable block 13 of aslide compression block 14 of theother slide - For this purpose, a
second front surface 19 of themovable block 13 presses against a second slidingsurface 20 of thecompression block 14. In greater detail, both theslides second seat movable block 13 and thecompression block 14 are formed. - In accordance with a preferred embodiment of the present invention, the
compression block 14 is provided with ashoulder 23 against which the abovementioned resiliently yielding means 17 engage. Advantageously, thesecond seat 22 has a form corresponding to that of thecompression block 14 and therefore has a similar shoulder 23' which is counter-shaped with respect to that of theblock 14. - On the
support body 3', 5 it is thus possible to form acavity 24 inside which thefirst spring 17 is inserted so that it acts on theshoulder 23 of thecompression block 14. - In accordance with an important characteristic feature of the present invention, it is envisaged using a
plate 25 of self-lubricating material inserted inside eachfirst seat 21 and arranged between the support body 3', 5' of therespective slide side surface 26 of themovable block 13, in order to favour sliding of the latter during its travel path A. - The self-lubricating plate may be advantageously made of PTFE (polytetrafluoroethylene, better known by the registered trademark Teflon®) or special sintered bronze or also of any other self-lubricating material with a low coefficient of friction.
- In accordance with a first embodiment of the present invention, illustrated in Figures 1-7, the self-
lubricating plate 25 is fixed onto theside surface 26 of themovable block 13 by means of the screws inserted inholes 60. - In accordance with a further embodiment of the present invention, illustrated in Figures 8-10, the self-
lubricating plate 25 is removably fixed inside a housing 27 formed on the support body 3', 5'. Removable fixing may be performed, for example, by means of a guide or by means of screwing means. - The purpose of this
plate 25 is to favour sliding of themovable block 13 inside itsfirst seat 21, without requiring the use of lubricants. - Moreover, in accordance with the invention, once the
plate 25 has become worn following numerous hours of operation, it may be easily replaced at very little cost and very quickly. - It should also be noted that, as the
plate 25 diminishes in thickness as a result of wear, thecompression block 14 is nevertheless always able to compensate for this variation as a result of thefirst spring 17 which always presses it against themovable block 13, without the formation of dangerous play resulting in the possibility of accumulation of dust from the stopper or other undesirable material. - Therefore, during operation of the block-support head 1, the
compression block 14 also performs, as the self-lubricatingplate 25 becomes worn, a second associated travel movement. - Advantageously the
side surface 26 of themovable block 13 which rests in a sliding manner on theplate 25 is substantially flat. This obviously helps reduce the difficulty of machining. - The self-lubricating
plate 15 may advantageously be provided withgrooves 61 on its sliding surface, able to receive dust or other material, therefore avoiding any risk of seizing. - It should also be remembered that the prior constructional solutions of movable blocks envisaged forming a portion of the block so that the latter was inserted into a guide generally in the form of a dovetail provided in the slide. This requirement, in accordance with the present invention, is less essential in view of the force exerted by the
compression block 14 on themovable block 13. - In fact, in accordance with the present invention, the movable block does not particularly need to be guided, as in the solutions of the prior art, since it is prevented from rotating about the axis of forward movement X of its travel path A by the pressing force exerted by the
compression block 14. - Alternatively, however, in order to ensure a greater degree of precision of movement of the
movable block 13 andcompression block 14, it is equally and advantageously possible to envisage configuring an upper portion thereof in the form of aslide 80 able to engage slidably in a correspondingcounter-shaped guide 81 formed in theslides - Operationally speaking, the block-support head 1 in question is functionally more reliable than the heads known hitherto, avoiding entirely the risk of seizing of the blocks and damaging of the stoppers during the corking operation.
- Advantageously, the head 1 according to the present invention has low production costs, since it does not require complex mechanical machining operations for its manufacture, and low maintenance costs since, in the event of wear, it is possible to replace simply only the self-lubricating
plate 25. - The invention this conceived therefore achieves the predefined objects.
- Obviously, it may also assume, in its practical embodiment, forms and configurations different from that illustrated above, without thereby departing from the present scope of protection. Moreover, all the details may be replaced by technically equivalent elements and the forms, dimensions and materials used may be of any nature according to requirements.
