Definitions

  • the present invention relates to vertical packaging machines.
  • a vertical packaging machine comprises a hollow forming tube with a longitudinal axis, an inlet and an outlet downstream of the inlet.
  • the longitudinal axis may be vertical or may be inclined with respect to the vertical.
  • the forming tube is configured to receive a continuous film on the outside and to give a tubular shape to the film, and to receive the products to be packaged through the inlet. The products pass through the forming tube and exit the forming tube through the outlet.
  • the machine comprises a longitudinal sealing tool for longitudinally sealing the longitudinal edges of the tubular shaped film surrounding the forming tube, thereby generating a film tube, and a transverse sealing and cutting device downstream of the forming tube, for cutting the film tube transversely with respect to the longitudinal axis of the forming tube and for sealing said film tube on both sides of the cut, when said sealing and cutting device is arranged in a closed position.
  • the operation of the sealing and cutting device results in a film tube closed at one end upstream of the cut and a package closed at both ends downstream of the cut. After sealing and cutting, the sealing and cutting device moves to an open position to allow the film tube to advance.
  • the product supplied to the forming tube is deposited on the closed end of the film tube after passing through the forming tube, but typically exits the forming tube with the sealing and cutting device in the closed position, reaching its destination by being deposited on the sealing and cutting device.
  • the sealing and cutting device moves to the open position, a longitudinal advance of the film tube and the product is generated, so that the product is downstream of the sealing and cutting device, and on the next actuation of the sealing and cutting device, the package generated downstream of the sealing and cutting device contains the product inside.
  • the product drop speed can be reduced, but this is not always sufficient and, furthermore, this slowing down implies a reduction in the machine's productivity.
  • CN217260887U discloses a solution of this type.
  • the machine described in this document comprises a protective device which can be opened and closed in a controlled manner by an actuator. When closed, the protective device creates a wedge-shaped space above the sealing and cutting device, which receives the product to be packaged, thus preventing the product from damaging the film tube. Subsequently, the protection device is caused actively to be opened to allow the product to fall until it contacts the film of the film tube and is packaged, thus reducing the speed at which the product hits the film tube.
  • WO2016/207138 Another prior art packaging machine is disclosed in WO2016/207138 .
  • the outlet port is provided with a pair of movable opposing flaps hinged thereto.
  • the hinge is formed of a flexible rubber material.
  • the object of the invention is to provide a vertical packaging machine, as defined in the claims.
  • the vertical packaging machine comprises a forming tube configured to receive a continuous film and to give a tubular shape to the film, the products to be packaged being supplied through the forming tube.
  • the machine comprises a sealing and cutting device downstream of the forming tube, which is configured to seal and cut such a continuous tubular shaped sheet and which is movable between an open position and a closed position; and a protection assembly which is arranged at least partially between the forming tube and the sealing and cutting device, which is movable between an operating position in which it interferes with the product path from the forming tube to the sealing and cutting device and a non-operating position in which it does not interfere with said path, and which comprises a first flexible protection element comprising a junction area joined to the forming tube. The junction area is facing the forming tube.
  • the first protection element is flexible.
  • the sealing and cutting device acts on the continuous tubular-shaped film (when moving from the open position to the closed position)
  • the sealing and cutting device displaces the tubular-shaped film (a film tube) with this actuation.
  • This displacement of the film tube causes a reduction of the cross-section of the film tube and further causes the film tube to press against the protective assembly.
  • Due to the flexible properties of the first protection element said pressure causes the first protection element to flex towards the product path (the protection assembly thus moves from the non-operational to the operational position).
  • the sealing and cutting tool is returned to its open position, the film tube no longer presses on the protection assembly and the flexible or elastic properties of the first protection element cause the protection assembly to return to its non-operational position.
  • the protection assembly further comprises a second protection element which is more rigid than the first protection element, which partially covers the first protection element at least between the junction area of the first protection element and the sealing and cutting device and which is attached to the first protection element. Being downstream of the junction area, the second protection element is then disposed downstream the forming tube and does not affect the flexure of the first protection element and, moreover, being attached to the first protection element, the second protection element moves together with the first protection element when the first protection element is flexed.
  • the second protection element covers the first protection element in such a way that, with the protection assembly in the operating position, a product delivered through the forming tube impacts against said second protection element on its way to the sealing and cutting device.
  • the first protection element flexes each time a package is produced. Due to the high number of flexes that the first protection element has to withstand, over time the material of which it is made may tend to degrade and parts of it may become detached, with the risk that these parts may be present in the final package.
  • the second protection element withstands the product's packaging each time a package is generated but does not need to have flexible properties as it is the first protection element that flexes, and can be made of a material that does not suffer said type of degradation and better withstands the product's impact, such as a rigid material such as metal or hard plastic. In this way optimum properties can be provided for each protection element, increasing the service life of both protection elements.
  • the protective assembly protects the film and, therefore, the final package, since it receives the impact of the product during its fall and the product contacts the film without force. Furthermore, in the proposed machine this is achieved without the need to use actuators to actively trigger the movement of the protection assembly, which moves between its operational and non-operational position passively. The absence of actuators to cause this movement simplifies the protection assembly, which reduces its size, facilitates maintenance and cleaning of both the protection assembly and the machine, and reduces its cost and therefore that of the machine.
  • the present invention relates to vertical packaging machines 100, such as the one shown in figure 1 by way of example.
  • the machine 100 comprises a hollow forming tube 1 configured to receive a continuous sheet 300 on the outside and to give a tubular shape to the said sheet 300, so as to obtain a sheet tube 301 enclosing the forming tube 1.
  • the forming tube 1 comprises a longitudinal axis 1.0 (vertical as in the case of the machine 100 of figure 1 , or inclined with respect to the vertical), an inlet opening through which it receives the products P to be packaged, and an outlet opening 1.2 downstream of the inlet opening.
  • the machine 100 further comprises a transverse sealing and cutting device 2 downstream of the forming tube 1, which is configured to transversely seal and cut the film tube 301 in a closed position (see figure 2 ) but allowing the passage of the film tube 301 in an open position (see figure 1 ); and a protection assembly 3 which is arranged at least partially between the forming tube 1 and the sealing and cutting device 2, and which comprises a first protection element 3.1 with a junction area 3.11 joined to the forming tube 1.
  • the sealing and cutting device 2 is configured to act on the film tube 301 when said sealing and cutting device 2 is moved from the open position to the closed position and to displace said film tube 301 as a result of said actuation, as previously described.
  • the sealing and cutting device 2 clamps the area of the film tube 301 which is at its height and causes a displacement therefore of said area (to clamp it) and also of at least part of the film tube 301 lying above said area, between the sealing and cutting device 2 and the forming tube 1.
  • the first protection element 3.1 comprises a material preferably adapted so that when the film tube 301 is displaced, the pressure exerted by said film tube 301 on said first protection element 3.1 causes said first protection element 3.1 to flex, although the machine 100 could additionally comprise a pushing device 4 to assist said flexure, as described below, thus ensuring the desired flexure under all circumstances.
  • the protection assembly 3 moves from a non-operational position (see Figures 1 and 3 ) in which it does not interfere with the product path P to an operational position (see Figure 2 ) in which it does interfere with said path.
  • the protection assembly 3 prevents the passage of the product P towards the sealing and cutting device 2 when it is in the operational position.
  • the sealing and cutting device 2 may be a conventional sealing and cutting device 2 comprising two sealing and cutting elements 2.1 and 2.2 facing each other between which the film tube 301 is clamped.
  • the sealing and cutting elements 2.1 and 2.2 are spaced apart from each other in such a way that the film tube 301 can move between them.
  • the sealing and cutting device 2 is moved to the closed position, the sealing and cutting elements 2.1 and 2.2 are moved closer together until the film tube 301 is clamped between them, and, preferably, the two sealing and cutting elements 2.1 and 2.2 are moved simultaneously for this approach.
  • Both sealing and cutting elements 2.1 and 2.2 can be actuated by one and the same actuator.
  • the pushing device 4 is arranged between the sealing and cutting device 2 and the forming tube 1 and is preferably attached to said sealing and cutting device 2 in such a way that it moves together with said sealing and cutting device 2.
  • the pushing device 4 also moves and acts on at least part of the film tube 301 which is between the forming tube 1 and the sealing and cutting device 2, in turn pushing the protection assembly 3.
  • the pushing device 4 comprises a first pushing element 4.1 attached to the first sealing and cutting element 2.1 such that both elements 4.1 and 2.1 move together, and a second pushing element 4.2 attached to the second sealing and cutting element 2.2 such that both elements 4.2 and 2.2 move together.
  • the separation distance between the pushing elements 4.1 and 4.2 is greater than the distance between the sealing and cutting elements 2.1 and 2.2, since between the pushing elements 4.1 and 4.2 is arranged at least one protection assembly 3 which is pushed by at least one of said pushing elements 4.1 and 4.2.
  • the machine 100 comprises two protection assemblies 3 facing each other and arranged between the pushing elements 4.1 and 4.2, a first protection assembly 3 being arranged between the first pushing element 4.1 and a second protection assembly 3 to be pushed by said first pushing element 4.1, and said second protection assembly 3 being arranged between the second pushing element 4.2 and the first protection assembly 3 to be pushed by said second pushing element 4.2.
  • the first protection element 3.1 of a protection assembly 3 may be made of a polymeric material comprising particles or pieces of metal. In this way, in the event that the first protection element 3.1 suffers degradation and part of its material becomes detached, it is possible to detect whether the detached material has fallen into the package together with the product P with, for example, X-rays.
  • the second protection element 3.2 may be made of a metallic material or a material comprising particles or pieces of metal, so that if for any reason part of this material becomes detached it can also be detected.
  • the machine 100 comprises at least one coupling device 3.3 for coupling together in a decoupling manner two corresponding elements 3.1, 3.2; 3.1, 1 of the machine 100, which may be part of the protective assembly 3, and which are shown in Figure 4 .
  • Said two elements can be the second protection element 3.2 and the first protection element 3.1 of the protection assembly, or said first protection element 3.1 and the forming tube 1.
  • the machine 100 may comprise at least one coupling device 3.3 for joining together the first protection element 3.1 of said protection assembly 3 and/or at least one coupling device 3.3 for joining together the first protection element 3.1 of said protection assembly 3 and the forming tube 1.
  • the coupling device 3.3 is configured to change position by a rotation and to, depending on its position, maintain the coupling or allow uncoupling between the two elements 3.1, 3.2; 3.1, 1 which it couples together.
  • the coupling device 3.3 comprises at least one face with a configuration adapted to allow the use of a tool such as a screwdriver for example (see figure 3 ), so that the user can generate such a rotation in a simple manner.
  • the coupling device 3.3 preferably comprises a longitudinal rod 3.30, a first platen 3.31 attached to a first end of said rod 3.30 and a second platen 3.32 attached to a second end of said rod 3.30 opposite to the first end.
  • the rod 3.30, the first platen 3.31 and the second platen 3.32 of the coupling device 3.3 preferably form a single piece.
  • the face of the coupling device 3.3 configured to be operable with a tool may be a face of either of the two platens 3.31 and 3.32, or indeed both platens 3.31 and 3.32 may be so configured to make the user's operation more flexible.
  • Each of the two elements 3.1, 3.2; 3.1, 1 coupled by at least one coupling device 3.3 comprises a respective through hole 3.10, 3.20; 3.5, 1.3 configured so that the first platen 3.31 of the coupling device 3.3 is prevented from passing through said through holes 3.10, 3.20; 3.5, 1.3 in at least a certain position of the coupling device 3.3; so that the rod 3.30 of said coupling device 3.3 can pass through said through holes 3.10, 3.20; 3.5, 1.3 in any position of the coupling device 3.3; and so that the second platen 3.32 of said coupling device 3.3 is prevented from passing through said through holes 3.10, 3.20; 3.5, 1.3 in at least one certain position of the coupling device 3.3.
  • the shape of the through holes 3.10, 3.20; 3.5, 1.3 is elongated.
  • said first protection element 3.1 comprises a through hole 3.5 in the junction area 3.11 and the forming tube 1 comprises a through hole 1.3 (see figure 5 ), said through holes 3.5 and 1.3 being configured as previously described.
  • the through hole 3.5 is configured to be pierced by a platen 3.31 or 3.32 of said coupling device 3.3 when said coupling device 3.3 is in a first determined position and wherein the through hole 1.3 is configured to be pierced by said platen 3.31 or 3.32 when said coupling device 3.3 is in a second determined position different from the first determined position, in such a way as to make it very difficult for the first protection element 3.1 of the protection assembly 3 and the forming tube 1 to be accidentally disengaged.
  • the through hole 3.5 may extend vertically and the through hole 1.3 may extend horizontally, or vice versa.
  • the coupling area 3.11 of the first protection element 3.1 can be arranged inside the forming tube 1 so that the coupling device 3.3 is accessible from the outside of the forming tube 1, thus facilitating coupling or uncoupling and preventing the first protection element 3.1 from rubbing against the film tube 301.
  • the forming tube 1 comprises an element 1.9 in the form of a plate, adhered to its surface, said element 1.9 comprising a through hole at least partially coinciding with the through hole 1.3 and which is passed through by the coupling device 3.3.
  • This element 1.9 provides a flat joining surface, contrary to the forming tube 1 where sometimes the surface may be curved, thus giving robustness to the joint between said forming tube 1 and the first protection element 3.1.
  • said first protection element 3.1 comprises a through hole 3.10 (preferably equivalent to through hole 3.5) and said second protection element 3.2 comprises a through hole 3.20, said through holes 3.10 and 3.20 being configured as previously described.
  • the through hole 3.10 is configured to be pierced by a platen 3.31 or 3.32 of said coupling device 3.3 when said coupling device 3.3 is in a first determined position and wherein the through hole 3.20 is configured to be pierced by said platen 3.31 or 3.32 when said coupling device 3.3 is in a first determined position, and wherein said through hole 3.20 is configured to be pierced by said platen 3.31 or 3.32 when said coupling device 3.3 is in a first determined position.31 or 3.32 when said coupling device 3.3 is in a second determined position different from the first determined position, in such a way as to make it very difficult for both protection elements 3.1 and 3.2 to be accidentally uncoupled.
  • the through hole 3.10 may extend vertically and the through hole 3.20 may extend horizontally, or vice versa.
  • the second protection element 3.2 comprises a plurality of through holes 3.20 and the protection assembly 3 comprises a coupling device 3.3 for each through hole 3.2.
  • the plurality of through holes 3.20 are preferably arranged closer to an edge of said second protection element 3.2 than to the centre of said second protection element 3.2, preventing or hindering the deposition of product residues P between both protection elements 3.1 and 3.2, and are evenly distributed to provide a better coupling.
  • the coupling device 3.3 may be configured to be arranged in a certain first position to allow a relative displacement between the first protection element 3.1 and the second protection element 3.2, in order to be able to decouple said protection elements 3.1 and 3.2 from each other and/or, if applicable, from the first protection element 3.1 and the forming tube 1.
  • said coupling device 3.3 may be configured to be arranged in a second determined position shown in Figure 3 , in order to prevent said displacement and to prevent said uncoupling between the two protection elements 3.1 and 3.2, and/or where applicable, between the first protection element 3.1 and the forming tube 1.
  • both protection elements 3.1 and 3.2 may be decoupled (and/or where applicable, the first protection element 3.1 and the forming tube 1), during normal operation of the machine 100 the said protection elements 3.1 and 3.2 (and/or if applicable, the first protection element 3.1 and the forming tube 1) remain securely coupled, the protection assembly 3 offering the protection previously mentioned.
  • the joining between the first protection element 3.1 of said protection assembly 3 and the forming tube 1 made with the coupling device 3.3 is thus stable, but can be undone and redone when required, by changing the position of the coupling device 3.3, to replace the protection assembly 3 or for maintenance work, for example.
  • the fact that the second protection element 3.2 is uncoupled from the first protection element 3.1 means that either of the two protection elements 3.1 and 3.2 can be replaced when required, without having to replace the whole protection assembly 3, since the service life of the first protection element 3.1 will be mainly conditioned by the fatigue generated by its flexing, whereas the service life of the second protection element 3.2 will be mainly conditioned by the impacts produced by the products P to be packaged, therefore it is not generally necessary to replace both protection elements 3.1, 3.2 at the same time, which reduces the cost of maintenance of the machine 100. Moreover, this also facilitates the cleaning of the protection assembly 3, since by uncoupling both protection elements 3.1 and 3.2, the whole of protection elements 3.1 and 3.2 can be accessed for cleaning.
  • the machine 100 comprises a plurality of coupling devices 3.3 for coupling with each other the first protection element 3.1 and the second protection element 3.2 of the protection assembly 3, and a plurality of coupling devices 3.3 for coupling with each other the first protection element 3.1 of the protection assembly 3 and the forming tube 1, as shown in the embodiment of the figures.
  • the protection assembly 3 may comprise a first protection element 3.1 and a plurality of second protection elements 3.2 as described.
  • the first protection element 3.1 may comprise a tubular shape (the part below the forming tube 1), such that when flexed, the protection assembly 3 stops the product P from falling and the product P cannot continue to fall until the sealing and cutting device 2 is opened. When the sealing and cutting tool 2 is opened, the protective assembly 3.1 is no longer depressed and returns to its initial position. This can be achieved with other shapes of the first protection element 3.1, such as a semitubular first protection element 3.1. In any of these options, the product P exiting the forming tube 1 impacts against the second protection elements 3.2.
