Description

Telescopic paper straw assembling apparatus and system

The object of the invention is a telescopic paper straw manufacturing apparatus and system.

The invention belongs to the field of apparatuses for manufacturing beverage drinking straws, in particular telescopic straws made of ecological, biodegradable materials such as paper.

Nowadays, ecological paper drinking straws are one of the most popular alternatives to standard plastic straws. There are various types of paper drinking straws, including one-piece straws, two-piece straws, straight straws and flexible, bendable straws. The present invention relates to a method of manufacturing two-piece straws, also known as telescopic straws, which have in their structure a locking latch which allows the two parts of the straws to be joined together in such a way that when one inner part of the straw is inserted into the other outer part of the straw a tight connection is provided. In addition, this type of connection makes it possible to slide the inner part of the straw into the inside of the outer part, thus to shorten the total length of the straw, for example in order to pack it in a foil. Such telescopic straws may be unfolded to their original size after unwrapping the foil, just before drinking.

Devices for assembling telescopic paper straws are known in the prior art. From the patent application JP1987055123, there is known an apparatus for assembling telescopic straws on a drum wherein a set of pushers working with raceways forcing the movement of the pushers is used for inserting the inner straw into the outer straw.

From the patent application JP1987183332, there is known an apparatus for making longitudinal creases forming locking latches of telescopic paper straws. That publication disclosed a longitudinal crease along a longitudinal axis of straws forming a telescopic straw.

The problem to be solved by the present invention is to achieve a spatially compact production device in which the straws forming the telescopic straw are creased and the telescopic straw is assembled to make a final product supplied to and removed from the production device in the form of multilayer mass flows.

The object of the invention is a telescopic paper straw assembling apparatus comprising a first container for feeding a straw of the first type, a second container for feeding a straw of the second type, a first forming unit for making a crease on the straw of the first type comprising a first drum conveyor, and a second forming unit for making a crease on the straw of the second type comprising a second drum conveyor. The apparatus further comprises an assembling unit for inserting the straw of the first type into the straw of the second type, thus forming a telescopic straw and an outlet for removing the telescopic straws. The apparatus is further characterised in that the first forming unit and the second forming unit have the first drum conveyor and the second drum conveyor positioned coaxially.

The apparatus is further characterised in that the first forming unit and the second forming unit are situated above the assembling unit.

The apparatus is further characterised by being provided with a creasing unit for making a crease at the end of the telescopic straw.

The apparatus is further characterised in that the first forming unit and the second forming unit as well as the assembling unit are arranged in a horizontal configuration.

The apparatus is further characterised in that the first forming unit and the second forming unit, the assembling unit and the creasing unit are arranged in a horizontal configuration.

The apparatus is further characterised in that a linear conveyor adapted to feed a single-layer stream of the telescopic straws is situated at the outlet of the apparatus.

The apparatus is further characterised in that the linear conveyor comprises a chain conveyor provided with support elements for individual telescopic straws.

The apparatus is further characterised in that the linear conveyor is positioned horizontally.

The apparatus is further characterised in that the assembling unit for inserting the straw of the first type into the straw of the second type, forming the telescopic straw, is provided with an inserting subunit adapted to initially insert the straw of the first type into the straw of the second type, and a pusher unit adapted to move the straw of the first type into the inside of the straw of the second type to a final position.

The object of the invention is also a telescopic paper straw assembling system provided with two telescopic paper straw manufacturing apparatuses wherein the outlets of both telescopic paper straw manufacturing apparatuses are connected to each other to form an outlet adapted to deliver a multilayer stream of the telescopic straws.

The system is further characterised in that the outlets of both telescopic straw manufacturing apparatuses are connected so that the telescopic straw streams merge, and a filling sensor is positioned above the merging point.

The system is further characterised by being provided with a feed channel for feeding the straw of the first type to both telescopic straw manufacturing apparatuses.

The system is further characterised by being provided with a feed channel for feeding the straw of the second type to both telescopic straw manufacturing apparatuses.

A telescopic paper straw assembling apparatus according to the invention may constitute a part of a production line for manufacturing telescopic straws, whereas the telescopic straw comprises straws of two types. The telescopic straw T comprises an inner straw M and an outer straw P (Fig. 1 and Fig. 2), whereas the inner straw has a smaller diameter than the outer straw, and preferably the straw of the first type M is obliquely ended on one side. In this description, the inner straw M of the telescopic straw T will also be referred to as the straw of the first type M, and the outer straw P of the telescopic straw T will also be referred to as the straw of the second type P. The production line may be supplied with straws of the first type of double length 2M, whereas by cutting one straw of the first type of double length 2M at an angle to the longitudinal axis two straws of the first type of single length M are formed. Moreover, the oblique cutting ensures that each straw has an oblique end adapted to pierce the beverage container. Similarly, straws of the second type of double length 2P may be provided, whereas by cutting one straw of the second type of double length 2P two straws of the second type of single length P are formed.

Fig. 3 shows the telescopic paper straw assembling apparatus in a first embodiment in a horizontal configuration, in a front view, whereas Fig. 3a shows the same apparatus in a perspective view. According to this embodiment, the straws of the first type M are fed in the form of a multilayer mass flow by means of a conveyor 5 through a feed channel 2 to a first container 1 of the straws of the first type M. The straws of the second type P are also fed in the form of a multilayer mass flow by means of the conveyor 5' through the feed channel 2' to the container 1 ' of the straws of the second type P. The conveyor 5, the feed channel 2 and the container 1 of the straws of the first type M are not visible in Fig. 3 because in this view they are obscured by the components carrying the straws of the second type P, which components are in the foreground, the components of the telescopic straw assembling apparatus being better visible in Fig. 3a. From the containers 1 , T the straws of the first type M and the straws of the second type P are fed by gravity onto the surfaces of a first receiving conveyor 6 and a second receiving conveyor 6' shown in developed view in Fig. 10. The receiving conveyors 6 and 6' may be embodied as coaxial drum conveyors, and may be integrated to form a single drum conveyor. The unilaterally obliquely ended straw of the first type M is fed in an orientation in which the oblique end faces the straw of the second type P. Next, the straw of the first type M is moved from the first receiving conveyor 6 by a transferring conveyor 7 to a first forming unit 8 comprising a first forming conveyor 20, a mounting roller 21 and forming rollers 22 making creases X (the forming unit is shown in a developed view in Fig. 11). The straw of the second type P is moved from the second receiving conveyor 6' by a transferring conveyor T to a second forming unit 8' comprising a second forming conveyor 20', a mounting roller 2T, and forming rollers 22' making creases Y (Fig. 11). Preferably, the first forming conveyor 20 and the second forming conveyor 20' are embodied as drum conveyors and are positioned coaxially. The first forming unit 8 makes creases X on the straw of the first type M, and the second forming unit 8' makes creases Y on the straw of the second type P. The creases X on the straw of the first type M and the creases Y on the straw of the second type P allow stopping the unfolding movement of the folded telescopic straw T and ensure the stability of the telescopic straw T when it is unfolded, i.e. in the extended configuration. The creases X and Y together form a locking latch. After forming the creases X and Y, the straws of the first type M and of the second type P pass through an assembling unit 10 (shown in a developed view in Figs. 11 and 12) which comprises assembling rollers 23 and 23' situated at the first forming conveyor 20 and the second forming conveyor 20', and a pusher unit 30 situated at the conveyor 24, provided with a cam 33 which moves a pusher 31 by means of a roller 32. Furthermore, the assembling unit may comprise a transferring conveyor 9 situated between the forming conveyor 20, 20' and the conveyor 24 in the assembling unit 10. The assembling unit 10 is adapted to insert the straw of the first type M into the straw of the second type P so that the telescopic straw T is formed. The embodiment of Fig. 3 further comprises a creasing unit 12 situated downstream of the assembling unit 10, whereas the telescopic straws T are transferred from the assembling unit 10 to the creasing unit by the transferring conveyor 11. The creasing unit 12, shown in a developed view in Fig. 13, is optional and is used to form a crease Z at the end of the folded telescopic straw T i.e. at the end of the straw of the second type P into which the straw of the first type M is inserted, the crease Z being formed on the side opposite to the oblique end of the straw of the first type M. The crease Z provides an additional protection against sliding out of the straw of the first type M from the straw of the second type P. From the creasing unit 12, the folded telescopic straws T are directed towards the outlet 13 which in this embodiment has the form of a conveyor adapted to carry a single layer of the telescopic straws T. In the embodiment shown, downstream of the outlet 13 there is situated a container 14 from which the telescopic straws move downwards to a mass flow conveyor 15. The conveyor 15 is adapted to convey the telescopic straws T in a plurality of layers to a receiving apparatus, for example to an apparatus for packaging the individual telescopic straws in a foil.

Fig. 4 shows a second embodiment of the telescopic paper straw assembling apparatus, also in a horizontal configuration. In this embodiment, the apparatus is not provided with the optional creasing unit 12 so that the folded telescopic straws are transferred from the assembling unit 10 directly towards the outlet 13. Fig. 5 shows the telescopic paper straw assembling apparatus in a further embodiment, in a vertical configuration, in front view. The vertical configuration of the telescopic paper straw assembling apparatus has the technical advantage of reducing the area occupied by the apparatus so that, while maintaining the same process capacity, it is possible to locate the apparatus in production buildings where a small working space is available. According to the embodiment of Fig. 5, the straws of the first type M are fed by the conveyor 5 through the feed channel 2, by gravity to the first container 1 of the straws of the first type M. The straws of the second type P are fed by the conveyor 5' through the feed channel 2' by gravity to the container T of the straws of the second type P. The conveyor 5, the feed channel 2 and the container 1 of the straws of the first type M are not visible in Fig. 5, in this embodiment they are obscured by components carrying the straws of the second type P, which components are in the foreground. From the containers 1 , 1 ' the straws of the first type M and the straws of the second type P are fed to receiving surfaces of the drum conveyors 6, 6'. Next, similar to the first embodiment, the straw of the first type M is moved from the first receiving conveyor 6 by the transferring conveyor 7 to the first forming unit 8 (shown in a developed view in Fig. 11 ) comprising the first forming conveyor 20, the mounting roller 21 and the forming rollers 22. Moreover, the forming unit 8 is situated underneath the drum conveyor 6. The straw of the second type P is moved from the second receiving conveyor 6' by the transferring conveyor T to the second forming unit 8' comprising the second forming conveyor 20', the mounting roller 2T and the forming rollers 22'. Similarly, the first forming conveyor 20 and the second forming conveyor 20', embodied as drum conveyors, are positioned coaxially. Similar to the first embodiment, after the straws of the first type M and the second type P have been formed, they are assembled in the assembling unit 10 which slides the straw of the first type M into the straw of the second type P so that the telescopic straw T is formed. The assembling unit 10 is built as in the first embodiment. The embodiment of Fig. 5 also comprises a creasing unit 12 which, in the vertical configuration, is positioned underneath the assembling unit 10. The folded telescopic straws T are conveyed from the creasing unit 12 through an outlet channel 16, which in this embodiment is a gravity channel in the form of a chute, the telescopic straws T from the outlet 13 travel to a container 14 and then onto a mass flow conveyor 15.

Fig. 5a shows the telescopic paper straw assembling apparatus in a further embodiment in a vertical configuration, in front view. In this embodiment, the container 1 of the straws of the first type M and the container T of the straws of the second type P are spaced apart, i.e. situated so that they are not next to each other (in the front view, i.e. as in Fig. 5 one after the other), allowing operators to access each of the containers from both sides. Such positioning of the containers 1 , T allows the operator to access and operate the apparatus more easily. In the embodiment shown in Fig. 5a, the straws of the first type M are fed by the conveyor 5 through the feed channel 2, by gravity to the first container 1 of the straws of the first type M. The straws of the second type P are fed by the conveyor 5' through the feed channel 2' by gravity to the container T of the straws of the second type P. From the container T and 1, respectively, the inner straws M and the outer straws P are fed to two separate drum conveyors 6, 6' and by means of two separate transferring conveyors 7', 7 are transferred to the forming units 8, 8'. The structure of the apparatus of Fig. 5a underneath the transferring conveyors 7', 7 is similar to the apparatus shown in Fig. 5.

Fig. 6 shows a telescopic paper straw assembling system provided with two apparatuses for manufacturing the telescopic paper straws as shown in Fig. 5. The first apparatus (on the right side of the figure) is as in Fig. 5, the second telescopic paper straw assembling apparatus (on the left side of the figure) is arranged so that it is a mirror image of the apparatus shown in Fig. 5. The second telescopic paper straw assembling apparatus of Fig. 6 has a conveyor 5A of straws of the first type M for conveying the straws to a feed channel 2A from where they are conveyed by gravity to a container 1 A of straws of the first type M. Furthermore, the second paper straw assembling apparatus has a conveyor 5A' of straws of the second type P for conveying the straws to a feed channel 2A' from where they are moved by gravity to the container 1 A' of straws of the second type P. The conveyor 5A of straws of the first type M, the feed channel 2A and the container 1 A of straws of the first type M of the second paper straw assembling apparatus are not visible in Fig. 6. Next, similar to the apparatus of Fig. 5, straws of the first type M as well as straws of the second type P are fed from the containers 1 A, 1 A' onto the surfaces of the drum conveyors 6A, 6A' and then through the transferring conveyor 7A, 7A' to the forming units 8A, 8A'. The formed straws of the first type M and of the second type P are assembled in the assembling unit 10A to the form of telescopic straws T and are transferred via the transferring conveyor 11 A to the creasing unit 12A. The first and second telescopic straw assembling units of Fig. 6 have a common outlet 17 comprising outlets 13, 13A in the form of a gravity chute from which the assembled telescopic straws T are transferred through a gravity channel 18 to an outlet 19 in the form of an outlet conveyor. The outlet 19 is adapted to supply a multilayer stream of the telescopic straws T. In addition, the first and second telescopic straw assembling apparatuses are respectively provided with containers 41, 42 and filling sensors 43, 44. The filling sensors 43, 44 send filling level signals to the controller which are processed to maintain an optimum filling level of the straws of the first type M and of the second type P with changing inflow rate of the straws of the first type M and of the second type P and outflow rate of the telescopic straws T. The system shown in Fig. 6 provides a high production efficiency.

Fig. 7 shows the telescopic paper straw assembling system in a second embodiment provided with two apparatuses for manufacturing the telescopic straws T. The system of Fig. 7 differs from the system of Fig. 6 in that the two telescopic paper straw T assembling apparatuses have one main supply channel 3 for straws of the first type M and a second main supply channel 3' for straws of the second type P, the main supply channel 3 for straws of the first type being invisible in Fig. 7. The main supply channel 3 for the straws of the first type M is divided into two supply channels 2, 2A connected with the the containers 1 , 1 A of the straws of the first type M. The main supply channel 3' for the straws of the second type P is divided into two supply channels 2', 2A' connected with the containers T, 1 A' of the straws of the second type P. Above the main feed channels 3, 3' there are filling sensors respectively 45 for the straws of the first type M and 45' for the straws of the second type P. The system shown in Fig. 7 is fed from two sides and is provided with two containers 48, 49 and two conveyors 46, 47 of the straws of the first type M, and with two containers 48', 49' and two conveyors 46', 47' of the straws of the second type P. An advantage of such solution is the application of a buffer connecting the flows which allows maintaining both assembling apparatuses in operation even if the inflow of the straws takes place only via conveyors situated on only one supply side.

Fig. 8 shows the telescopic paper straw assembling system in a third embodiment. The system has such structure as shown in Fig. 7. In the embodiment of Fig. 8, different outlets of individual telescopic straw assembling apparatuses were applied. The assembled telescopic straws T of the first and second straw assembling apparatuses are conveyed by a first linear conveyor 50 and a second linear conveyor 50A to a common outlet channel 18, and then the accumulated flows of the telescopic straws T from both straw assembling apparatuses are conveyed to a single outlet 19 in the form of an outlet conveyor. The system is provided with a filling sensor 52 situated above the outlet channel 18. An advantage of such solution is the possibility of maintaining the flow of assembled telescopic straws removed from the system when one of the assembling apparatuses is stopped.

Fig. 9 shows the telescopic paper straw assembling system in a fourth embodiment which differs from the systems shown in Fig. 7 and Fig. 8 in the shape of the outlets of the telescopic straw T assembling apparatuses. The telescopic straw T assembling apparatuses constituting the system shown in Fig. 9 are ended respectively with a first linear conveying unit 51 and a second linear conveying unit 51 A which convey the assembled telescopic straws T to the output channel 18 and further to the outlet 19. Both the linear conveying unit 51 and the linear conveying unit 51 A receive the individual telescopic straws from the creasing units 12, 12A in the form of drum conveyors. The linear conveying unit may be provided with individual support elements ended with cylindrical concave surfaces adapted to the diameter of the telescopic straws, whereas the individual support elements may be attached to chain conveyor links. The system is provided with a filling sensor 52 situated above the outlet channel 18. The system shown in Fig. 9 allows the passage from the linear conveyors 51 , 51 A receiving the telescopic straws T individually to a multilayer outlet stream of the telescopic straws T so that a high productive efficiency can be achieved.

Fig. 10 shows a developed view of the lateral surface of the drum conveyors 6, 6' of the telescopic paper straw T assembling apparatus. As shown in Fig. 10, the straws of the first type M are transferred to the lateral surface of the drum conveyor 6 from the container 1, while the straws of the second type P are transferred to the lateral surface of the drum conveyor 6' from the container T.

Fig. 11 shows a developed view of the lateral surface of the drum conveyor 20 of the first forming unit 8 and the drum conveyor 20' of the second forming unit 8'. The straws of the first type M are moved friction ally by the rotating roller 21 having a concave lateral surface towards the forming rollers 22 and are creased by means of the forming rollers 22 situated above the surface of the drum conveyor 20. The straws of the second type P are moved frictionally by the rotating roller 2T having a concave lateral surface towards the forming rollers 22' and are creased by means of the forming rollers 22' situated above the surface of the drum conveyor 20'. As a result of creasing of the straws of the first type M and the straws of the second type P, creases X, Y are formed at the ends of the straws to form locking elements so that the straws M and P, when assembled to form the telescopic straw T maintain axial stability in the unfolded configuration and in addition, in the course of unfolding of the telescopic straw the unfolding movement is interlocked, i.e. stopped on the locking elements. As shown in Fig. 11, above the drum conveyors 20, 20' there may be situated assembling rollers 23, 23' belonging to the assembling unit 10 which rotate in opposite directions and by means of which the straws M and P are frictionally pushed and the straw of the first type M is initially inserted into the straw of the second type P. The assembling rollers 23, 23' constitute an inserting unit 25.

Figs. 11 and 12 show a developed view of a part of the lateral surface of the assembling unit 10. Preferably, this unit comprises a pusher unit 30 comprising an assembling mandrel 31 , a guide roller 32 and a cam 33. The pusher unit 30 moves the straw of the first type M by means of the assembling mandrel 31 into the inside of the straw of the second type P, to a final position i.e. to the form of an assembled telescopic straw T. In the embodiment shown, the telescopic straw T is assembled in two stages, the first stage being carried out frictionally on the drum conveyor 20 and 20' by means of the rollers 23, 23', and the second stage being carried out by means of the pusher unit 30 on the drum conveyor 24.

Fig. 13 shows a developed view of the lateral surface of the creasing unit 12. The creasing unit is provided with a pressure element 34, a roller 35 and a cam 36 used to make a crease Z at the end of the assembled telescopic straw T i.e. at the end of the straw of the second type P into which the straw of the first type M is inserted, the straw of the first type M being completely inserted into the inside of the straw of the second type P. The crease Z at the end of the straw of the second type P provides additional protection against the straw of the first type M sliding out of the straw of the second type P.
