    The invention relates to a method for attaching an elongated suction tube to a side wall of a container, wrapped in a sheath of thin elastic material and separated by a bend zone into sections of different lengths.
    It is known to mount oblong objects such as suction tubes, spoons, etc. to the walls of packaging containers.
    There is a problem with the attachment of the suction tubes, the length of which significantly exceeds the length of the diagonal of the side wall of the container. This problem is solved by using telescopic suction tubes, i.e. two tubes inserted one into the other when they are attached to the wall of the container, but when used they are telescopically protruding one relative to the other, thus forming a sufficiently long suction tube.
    It is known to use flexible suction tubes that can be bent over the corrugated section and which are thus either bent to form a U-shape or give them a different shape, with the result that the bent suction tube can be located on the side wall of the container.
    In order to maintain hygiene, the suction tubes attached to the containers are covered with a protective sheath, preferably plastic, and the suction tube is fed to the container in the form of a web of suction tubes attached together. The individual suction tubes are separated from the web along with the aoe sheath by cutting the web in pressurized zones located between the shells.
    It was, however, found that the fastening of such a suction tube in a shell that is longer than the diagonal of the container wall (packaging causes difficulties.

    since the suction tube, together with its shell, in addition to being attached to the side wall of the container, must be bent in a special way so as to be placed on this wall.
    The aim of the invention is to improve the quality of fastening.
    This goal is achieved by applying a thermally activated binding agent to the side wall of the container. Then, a suction tube wrapped in a sheath of thin elastic material is attached to this wall, the length of which exceeds the diagonal length of the side wall of the container. The tubule is divided by a bend zone into areas of different lengths. The suction tube is fixed to the wall of the container by placing a larger section diagonally of the wall, an inflection zone in the corner of the wall, and a smaller section above the container and bending the protruding portion of the suction tube before applying it to the side wall of the container and contacting it. on which the thermally activated binding agent was previously applied. In this case, the bending of the portion protruding above the container and wrapped up in the shell of the suction tube is carried out by directing this portion initially parallel to the plane of the side wall of the container, and so. that the shell in the inflection zone protrudes above the upper corner of the container, then this section is directed away from the side wall of the container and after that it is pressed against the wall sections to which the thermally activated binding agent has previously been applied.
    Figure 1 shows the canvas wrapped in the shell of the suction tubes with corrugated zones of inflection; 2 shows a container with a bent suction tube attached to it; FIG. 3 shows an installation for fastening the suction tubes to a packaging container; 4 shows a rotating drum for fastening the suction tubes; 5 to 9 show successive stages of the fastening process.
    FIG. 1 shows a sheet 1 of adhered instead of thin plastic shells with suction tubes 2. placed in these shells 3. The material of the shells 3 is sealed with itself in zones 4, and the individual wrapped suction tubes 2 are produced by cutting the blade 1 into hermetic zones 4. After of this, each separated suction tube 2 will be entirely
    closed with its shell 3. The suction tubes 2 consist of two straight sections 5 and 6 and an intermediate corrugated section 7 that is able to bend (bending zones
    tubules). As shown in Fig. 2, the suction tube 2 with its shell 3 is designed to be attached to the side wall of the container 8 and with its help the contents of the container 8 is made available by
    removing the suction tube 2 together with its shell 3 from the side wall of the container 8, after which the suction tube 2 is released from its shell 3 and inserted into the hole 9 made in the container
    8. The suction tube 2 (Fig. 2) has a total length such that it cannot completely fit along the side wall of the container 8 without giving it a U-shape, while bending is performed
    the corrugated section 7 on the suction tube 2. In addition to the corrugated section 7, the suction tube 2, as noted earlier, has two straight sections 5 and 6, while section 5 has a length which
    almost corresponds to or slightly less than the length of the diagonal of the side wall of the container 8, while the length of the smaller section 6 of the suction tube 2 is equal to or slightly less than the length of one of the side edges of the container 8.
    One of the problems that arise when attaching the suction tube 2 in the shell 3 is that not only the suction tube 3, but also the shell 3 must bend. At the same time, it was found that voltages easily appear in the sealed sections of the shell 3 along the outer curved part in that part
    shell, which is closer to the corrugated section 7. These stresses cause a certain deformation of the shell 3, which is manifested in the fact that the sealed edges of the shell 3 will
    protrude beyond the side wall of container 8 instead of adhering tightly to it. The reason why the side of the shell 3 facing the container 8 must fit snugly against its side wall is that. that a large contact surface is reached between the shell 3 by the activated binding agent, previously deposited on the side wall of the packaging container 8 and promoting adhesion, and also that the protruding edge of the shell 3 can contribute to tearing the suction tube 2 together with the shell 3 from the container 8 in the process transportation, loading and unloading.
    The fastening of the suction tube 2 can be significantly achieved using the installation shown in FIG. This installation comprises a conveyor 10, by means of which the packaging containers 8 are moved to the position in which the binding agent is applied and the suction tube 2, which is in the sheath 3, is attached. The conveyor 1E can be moved continuously or periodically depending on the design of the rest of the installation.
    In this case, it is assumed that it moves periodically. Packaging containers 8, which are fed from a magazine or filling machine during operation, are picked up by the leads of the conveyor cartridge 10 and sent past the glue-maker 11 to apply the activated binding agent. In this case, the binding agent is a hot melt, which is a mixture of wax and plastic, which has a good adhesiveness and a low melting point. Thanks to glue, which is hard and non-sticky at ordinary room temperature, it quickly seizes and provides a firm grip as soon as the temperature becomes 50-60 ° C.
    The binding agent is extruded under pressure through dies (not shown) provided in the gluing machine 11. The machine has two dies, one of which is set just above the lower edge of the conveyor 10, and the other just below the upper edge of the packaging container 8 By means of these matrices, the corresponding amount of binding agent is extruded onto the side wall of the packaging container 8 along the portion where the shell 3 of the suction tube 2 is to be fixed. Since the said matrices are located at different heights.:, the areas to which the binding agent is applied may be on two levels, counting from the base of the container 8. In this case, one section with the binding agent is located in the lower part of the container 8 near its one corner, then as two other or more areas with a bonding agent are located on the upper side edge of the packaging container 8. To maintain the packaging containers 8 in the desired position, the conveyor 10 provides rollers 12 mounted at a level slightly above the lower edge of the conveyor 10, with corresponding to the height of the packaging containers 8. Instead of the rollers 12, an endless belt may be used that passes over the conveyor
    10, with the lower part of the tape extending at a level corresponding to the height of the packaging containers 8. The suction tubes 2, which are located in the shells 3, are fed to
    blade 1 around rotary drum 13.
    Using separating means interacting with the drum 13, the individual
    0 suction tubes 2 together with their shells 3, which are held in slots 14 located parallel to the axis of rotation of the drum 13 along its periphery. The drum 13 is intended for synchronous rotation with
    5 by moving the conveyor 1 so that the packing container 8 is positioned with its side wall directly in front of the drum 13, when the suction tube 2 still held by the drum 13 is transferred from the drum 13 to the packaging container 8. The transfer can be done so that movement toward the packaging container 8 can be communicated to the drum 13, and that the rotation of the drum 13
    5 is synchronized with conveyor 1 so that the lower portion 5 of the suction tube 2 will be located diagonally on the wall of the passing or supplied container 8, and that the shell 3, closing the end portions 5 of the suction tube 2, is brought into contact with the activated binding agent, previously applied, and the shell 3 is held together with a bonding agent deposited on the wall
    5 packing container 8.
    In accordance with the design shown in FIG. 2, the drum 13 does not perform a reciprocating movement relative to the conveyor.
    0 10 and packaging containers 8 moving along it, and is provided with transmitting devices in the form of fingers 15, which squeeze out the suction tube 2 together with its shell 3 from the sockets 14 of the drum
    5 13. and the shell 3, together with its suction tube 2, is pressed tightly against the packaging container 8, which enters the position in front of the drum 13 in such a way that the longer straight section 5
    The suction tube 2 is attached with its shell 3 under the diagonal to the wall of the container 8.
    As shown in FIG. 3, the drum 13 is mounted with an inclination relative to the plane
    5 of the movement of the conveyor 10, which secures the suction tube 2 diagonally to the side wall of the container 8. The installation comprising a drum 13 that moves relative to the packaging containers 8 is used mainly
    In this case, when the packaging containers 8 are moved by the conveyor 10 continuously, the installation with the stepped or stepwise rotation of the drum 13 and the retractable fingers 15 is used in the cases when the packaging containers 8 are moved by the conveyor 10 stepwise. After the lower straight section 5 of a greater length of the suction tube 2 is fixed diagonally to the side surface of the packaging container 8, the latter moves further along the conveyor 10 and enters the bending device 16, with which the protruding straight section 6 of a shorter suction length the tube 2 is bent downward, taking a horizontal position, as a result of which it will be positioned against the side surface of the packaging container 8, and the shell 3 comes into contact with the previously applied activated binding agent. To hold the folded portion 6 until the glue hardens, there are a series of rollers 17 installed so that they are pressed against the portion 16 of the suction tube 2 when the container 8 is moved. After the rollers 17, the suction tube 2 remains attached to the wall of the packaging the container 8 in a desired manner and the container 8 provided with the suction tube 2 can be directed to the packaging.
    The rotating drum 13 for fastening the suction tube 2 is shown in Figs. 3 and 4. As noted, the drum 13 is designed to synchronously rotate with the conveyor 10. This synchronization can be carried out mechanically, but preferably when the rotational movement of the drum 13 is controlled and started using a photosensor (not shown) that determines the position of the packaging container 8 moving in the conveyor 10.
    The photo sensor can be used so as to control the glue glue unit 11, as well as the drum 13. In this case, applying the adhesive substance and supplying the new suction tube 2 will occur only when the conveyor 10 actually delivers the container 8. As can be seen from FIG. showing the cross section of the drum 13, the suction tubes 2 together with the shells 3 are located in slots 14 evenly spaced around the periphery of the drum 13. The suction tubes 2 are fed to the drum 13 in the form of a web 1, as described cum earlier passing through rollers 18 so
    that the web 1 with the suction tubes 2 is evenly distributed along one suction tube 2 to the nest 14, while, as the sealed sections of the 4 shells
    3 between the suction tubes 2 will be placed on the protruding portions 19 defining the boundaries of the sockets 14. The individual suction tubes 2 closed by the shells 3 are separated from one another
    0 by means of a knife 20 driven by a pneumatic cylinder 21, which is inserted into the gap 22 formed between the protruding portions 19. As a result, the sealed portion of the shell 3 is cut and
    5 the wrapped suction tube 2 is separated from the blade 1 from the suction tubes 2. The separated suction tube 2 cannot fall out of the slot 14, because a catching device or a mesh 23 is installed around the drum 13. The separated suction tube 2 will move forward in its slot 14 stepwise until it reaches the position corresponding to the trailing edge of the grid 23.
    5 In this position, the suction tube 2 is placed directly in front of the packaging container 8 moving on the conveyor 10, and the suction tube 2 is transferred from the drum 13 to the packaging container 8
    0 using finger 15, which is at its
    turning takes out the tube 2 from the socket 14
    and presses against the packing container 8.
    4, the finger 15 is shown in the allotted
    position and in the extended position in
    5 wherein the suction tube 2 is transmitted. The finger 15 rotates around an axis 24, the operation of which is controlled by a photosensor determining the position of the packaging container 8 moved by the transport 10. As shown in FIG. 3, the drum 13 is provided with recesses 26 in which the fingers 15 can move.
    The drum 13 is mounted with the possibility of easy replacement so that you can
    5 it was necessary to install tubes 2 of different diameters or lengths, and the angle of inclination of the axis on which the drum 13 is mounted can be adjusted so that it will correspond to the angle of the diagonal of the container 8,
    0 of the supplying suction tube 2. After the passage of the drum 13, the container 8 has the form shown in FIG. 5, where the container 8 is shown from the side and from the front in the direction of its transport. The nanosecond binding agent (glue) is shown in the form of round sections 26, which may also have an elongated shape. As shown in FIG. 5, the portion 5 of the suction tube 2 is attached to the side wall of the packaging container 8, while the protruding portion 6 of the tube 2 is free and protrudes beyond the container 8. The bending device 16 shown in FIG. 3 contains mainly three rollers, in particular rollers 27, 28 and 29, which in fig. 7, 8 are shown separately, but which in the device interact with each other, as shown in fig. 3
    The bending of the protruding portion 6 begins when the packaging container 8, when moving along the conveyor 10, passes by the conical roller 27 (Fig. B). The protruding portion 6 of the suction tube 2 is folded backward, while bending occurs along the corrugated portion 7 of the suction tube 2 Due to the fact that the roller 27 is conical, the portion 6 of the suction tube 2 will be slightly pressed above the packing container 8. This means that the bend point 30 of the shell 3 around the suction tube 2 will protrude above the upper angle of the container 8 and such lateral displacement of the section 6 leads to the fact that the shell 3 does not protrude beyond the limits of the container 8, but fits tightly to its side surface. Further bending of the portion 6 of the suction tube 2 occurs as shown in FIG. 7, using a tapered roller 28, the taper of which is directed in the direction opposite to the taper of roller 27. This means that section B will now be displaced several laterally from packing container 8 so as to ensure final bending of section 6 and that none of the protruding edges of the shell 3 could not stick to the container 8 from above. The final bending of the section 6 is carried out with the help of the roller 29 shown in FIG. 8. This roller is cylindrical and has a protrusion with a transition from a cylindrical surface of smaller diameter to a cylindrical surface of larger diameter. A smaller diameter cylindrical surface is designed to be placed on the upper end surface of the packaging container 8. While the larger diameter surface of the roller 29 is the final bending of section 6 to the desired position in which it is close to the wall of container 8, and the shell 3 around the section 6 of the suction tube 2 pressed against the binder
    previously applied agent, as a result of which the shell 3 is attached to the side wall of the container 8.
    As shown in Fig. 9, a portion 6 of the suction tube 2 is held in a bent position using a double tapered roller 31 until the glue hardens and the suction tube 2 is securely attached. A device may be used to hold the suction tube 5, which is attached first to the packing container 8, while it takes time to set and set the binding agent.
    side press (not shown), for example, in the form of an endless pressure band. The fastening of the suction tubes to the packaging containers carried out in accordance with the invention is strong and reliable.
