Definitions

  • the present invention is related to package thermoforming machines, and more specifically to thermoforming machines comprising a guide device for guiding a band or strip of packaging material which enables sanitizing all its components.
  • Thermoforming machines convey at least one band or strip of material that is used in a packaging process by means of lateral conveying means, associated with the longitudinal edges of the band.
  • the conveying means (chains, belts or equivalent elements) can be provided with means for securing the band or strip, for example, with clamps or with pins, such that as the conveying means move, they drive the band or the strip in a forward movement direction of the machine.
  • the conveying means are guided by guides which, among other things, serve to keep the conveying means correctly placed and to withstand the forces that the band or strip exerts in the direction perpendicular to the forward movement direction of the conveying means. In other words, the guides serve to keep the conveying means correctly placed and to prevent their lateral movement, while at the same the time allowing their longitudinal movement to drive or convey the band or strip.
  • a problem that has been detected in relation to these machines is that the guides, such as those known through DE-A-4314550 for example, can have problems related to the cleaning and sanitizing of the machines. For example, there can be gaps on the outer side of the chain, i.e., on the side of the chain opposite the side facing the band or strip to be conveyed, that are difficult to access. Given that cleaning and sanitizing are very important aspects in many packaging machines, for example, in food product packaging machines, it may be appropriate for all the components of the machine to be easy to access for performing cleaning and/or sterilization operations.
  • WO-A-2009/080293 describes a solution based on a guide profile which has access holes in its upper part which serve for cleaning the chain and the guide from above.
  • EP-A-1816075 proposes a solution based on an arrangement of guide elements at a distance from the profile that secures them, and/or in the presence of access holes in said profile, such that the outer side of the corresponding conveyor chain is easy to access.
  • more or less open guides to facilitate cleaning can be an attractive solution, but it can also involve drawbacks, for example, due to the fact that the holes or openings can be a possible entryway for dirt from outside, or because it is not possible to clean the zones of the guide in direct contact with the chain, this being able to generate focal points of contamination when food products are packaged.
  • more or less open guides also hinder cleaning the zones of the chain in direct contact with the guide, because it is only possible to clean these zones of the chain in those places of the machine where the chain moves forward without being guided.
  • the aforementioned solutions also have drawbacks from the cost viewpoint because they require a greater number of machining operations and/or a greater number of parts and/or longer assembly and disassembly times, in addition to the additional risk entailed for the operators to have access to the mobile parts of the machine, in this case, access to the chain through the openings of the guide.
  • the object of the invention is to provide a thermoforming machine as described in the claims.
  • the thermoforming machine of the invention comprises conveying means (chains, belts or equivalent elements) for conveying a band of material, such as a strip or the like, in a forward movement direction of the machine.
  • the conveying means are configured to interact with the longitudinal edges of the band to be conveyed by means of securing elements, for example, by means of clamps or pins, as is conventional and described in document EP-A-1816075 , for example.
  • the machine further comprises at least one guide device for guiding the conveying means in the forward movement direction.
  • the guide devices therefore serve to maintain the correct position of the conveying means and to counteract the forces that the band exerts in the transverse direction of the machine.
  • the guide device comprises a base support including at least one profile and at least one lower guide element which are attached to one another (although they could be a single element instead of being two attached elements), at least one upper guide element, and a channel for the conveying means, the channel being defined between said lower guide element and said upper guide element, and the channel being configured to allow the guided forward movement of the conveying means therethrough, to drive said band of material, during machine operation.
  • the upper guide element can establish an upper guide track and the lower guide element can establish a lower guide track
  • the conveying means can slide in the channel established between both tracks, the conveying means in turn being able to comprise lateral elements that are located on both sides of said tracks, such that the conveying means are guided by the tracks, as is conventional and described in EP-A-1816075 , for example, which reflects several arrangements of guide tracks and conveying means corresponding to a chain.
  • the upper guide element is detachably coupled to the base support to allow access to the conveying means to perform cleaning operations.
  • the arrangement of the upper guide element allows disassembling the upper guide element for cleaning operations. Since the upper guide element together with the lower guide element establishes the channel through which the conveying means pass, by disassembling the upper guide element the conveying means and the gap through which the conveying means move can be accessed, whereby both can be easily cleaned. It is therefore possible to clean the channel, the surfaces of the upper guide element and of the lower guide element interacting with the conveying means, and it is also possible to clean the surfaces of the conveying means. In other words, good access to the zones and surfaces that must be cleaned can be achieved without needing to provide holes or gaps in or between the different elements when they are in their assembled or working position.
  • Figure 1 shows by way of example an embodiment of the package thermoforming machine 100, comprising a plurality of stations corresponding to a lower band or strip entrance 101, a forming station 102, a welding station 103, an electrical cabinet 104, an upper band or strip entrance 105, a transverse cutting device 106, a longitudinal cutting device 107, lateral guards and internal mechanisms 108, and a product exit station 109.
  • a thermoforming machine comprising these stations is of conventional use, and furthermore there is a wide variety of such machines, so it is not described in greater detail in this description.
  • the machine 100 comprises conveying means 10 on either side, parallel to one another, between which the band or strip, such as a chain, a belt or an equivalent element, is arranged and which interact with the longitudinal edges of the band or strip by means of clamps 90 or pins or equivalent elements for example, the conveying means 10 driving the band or strip in a forward movement direction L of the machine 100 with their movement.
  • the machine 100 comprises at least one guide device 110 for guiding the conveying means 10.
  • chain 10 is used instead of “conveying means 10" for the sake of clarity, but this does not limit the invention to the use of a chain, being able to use a belt or any other equivalent element.
  • Figures 2 , 3 and 4 illustrate an embodiment of a sector of the guide device 110 of the machine 100.
  • the guide device 110 comprises a base support including at least one profile 4 and at least one lower guide element 2 which are attached to one another (although they could be a single element instead of being two attached elements), at least one upper guide element 1, and a channel 3 which is defined between both guide elements 1 and 2 and which is configured to allow and guide the guided forward movement of the chain 10 therethrough to drive the band or strip, the guide elements 1 and 2 together defining a type of profile that is substantially C-shaped.
  • Figures 2 and 3 show a sector of the chain 10 in the forward movement path of the chain 10 (the upper sector) and a sector of the chain 10 in the return path (the lower sector), and Figure 11C shows a link of the chain 10 in the forward movement path and a link of the chain 10 in the return path.
  • the upper guide element 1 is preferably attached to the base support by sliding, which allows quick and easy assembly and disassembly thereof, which can be implemented with simple structures. In other words, this solution can be advantageous from both the functional viewpoint and from the structural viewpoint. For example, the need for manipulating screws, nuts or bolts in relation to the assembly and/or disassembly of the upper guide element 1 can be prevented.
  • the upper guide element 1 preferably comprises a machined, extruded or molded profile 11 which establishes an upper guide track 16.
  • the upper guide element 1 is attached to the base support by means of at least one groove 5, 5', 5" and at least one attachment element 12, 12', 12", 12"' cooperating between them, different configurations being possible:
  • the groove 5, 5', 5" can be configured to receive at least one attachment element 12, 12', 12", 12"' or the like, such that the attachment between the upper guide element 1 and the base support is caused by the fitting of at least one of the attachment elements 12, 12', 12", 12"' in a corresponding groove 5, 5', 5" preferably by sliding. Fitting based on grooves represents a simple solution from the structural and functional viewpoint.
  • the upper guide element 1 comprises the attachment element 12, as shown by way of example in Figures 5 and 6 , and, as shown by way of example in Figures 7A, 7B and 7C , the groove 5 is in the profile 4 of the base support.
  • the groove 5 can be arranged in the upper part of the profile 4, being open and accessible from the upper part of said profile 4, and the attachment element 12 of the upper guide element 1 cooperates with the groove 5 so that the upper guide element 1 is attached to the base support.
  • the attachment element 12 corresponds in this case to a projection of the upper guide element 1 prolonging in a substantially horizontal manner, in the form of bolts for example, and comprising a rod 12A traversing the groove 5.
  • the attachment element 12 can further comprise a head 12B which is arranged in an outer side of the profile 4 when the upper guide element 1 is attached to the base support and is configured to not be able to traverse the groove 5.
  • An attachment element 12 can be threaded for example, as can be deduced from Figure 4 for example, where it is shown how a plurality of upper guide elements 1 are provided with attachment elements 12, which are screwed into a corresponding bushing 12C located inside the upper guide element 1, to then fit the attachment element 12 in the groove 5 located in the upper edge of the profile 4.
  • the upper guide element 1 preferably comprises a plurality of attachment elements 12, the profile 4 comprising at least one groove 5 for each attachment element 12 of the upper guide element 1.
  • the upper guide element 1 can also comprise a gripping element 12D, which preferably corresponds to a projection in the form of a bolt or a grip projecting from the attachment elements 12, being able to correspond to an extension of the rod 12A behind the head 12B to provide a grip for the operator in the assembly and disassembly process of the upper guide element 1.
  • a gripping element 12D which preferably corresponds to a projection in the form of a bolt or a grip projecting from the attachment elements 12, being able to correspond to an extension of the rod 12A behind the head 12B to provide a grip for the operator in the assembly and disassembly process of the upper guide element 1.
  • the upper guide element 1 further comprises a prolongation 19 extending towards the lower guide element 2 when the upper guide element 1 is attached to the base support, laterally delimiting the channel 3, such that the profile 4 does not delimit the channel 3 and, since the upper guide element 1 is detachable, the prolongation 19 can be easily cleaned (in a simpler manner than the profile 4 can be), improving access for cleaning the walls delimiting the channel 3.
  • the upper guide element 1 additionally comprises an attachment element 12" arranged in the prolongation 19, cooperating with a groove 5' arranged in the base support, preferably in the lower guide element 2 or between the lower guide element 2 and the profile 4, the groove 5' being suitable for clamping the attachment element 12", the upper guide element 1 thus counteracting transverse forces that the band exerts in the direction perpendicular to the forward movement direction L, without being detached from the profile 4.
  • the attachment element 12" can correspond to a projection or the like, or to the end of the prolongation 19.
  • the upper guide element 1 can comprise a prolongation 19 in any of its embodiments and/or configurations, not only in the preferred embodiment.
  • a first configuration of the groove 5 corresponds to the configuration depicted by way of example in Figures 7A, 7B and 7C .
  • the groove 5 comprises a specific orientation allowing motion of the upper guide element 1 in the forward movement direction of the chain 10 in order to be attached to the base support.
  • the upper guide element 1 being able to become detached from the base support during the packaging process due to vibrations and/or forces it may withstand during said process, for example, is thereby hindered.
  • the orientation of the groove 5 can be substantially oblique in the forward movement direction of the chain 10 for the interlocking of the attachment element 12.
  • the groove 5 can be substantially L-shaped. Therefore, to fit the upper guide element 1 in the profile 4 a first motion can be performed substantially in a first direction, for example, in a vertical direction, and a second motion can be performed in a second direction, for example, in a horizontal direction in the forward movement direction of the chain 10. Both configurations of the groove 5 prevent the attachment element 12 from being able to become decoupled from the groove 5 due to a purely vertical motion.
  • the profile 4 can be metallic and can correspond to a single longitudinal element, or it can be formed by a plurality of longitudinal elements which are longitudinally attached to one another.
  • Each longitudinal element can have a length of one or several meters, for example, five meters or longer, depending on the needs of the machine 100.
  • the upper guide element 1 further comprises at least one flange 1A projecting at an upper end of the upper guide element 1 in the direction opposite the chain 10 when the upper guide element 1 is attached to the base support, the flange 1A defining a preferably longitudinal groove 5" suitable for clamping an attachment element 12"' of the profile 4 when the upper guide element 1 is attached to the base support. It is therefore assured to a greater extent that the upper guide element 1 and the base support are attached to one another.
  • the groove 5" comprises a substantially identical or slightly greater width than the width of the attachment element 12"' of the profile 4, so that the profile 4 is clamped by the groove 5" of the flange 1A and so that the upper guide element 1 withstands transverse forces that the strip may exert without becoming detached from the profile 4.
  • the attachment element 12"' therefore corresponds to the upper end of the profile 4.
  • FIGS 8 and 9 show a lower guide element 2 of the preferred embodiment of the invention by way of example.
  • the lower guide element 2 comprises a machined or extruded or molded profile 23 that is longer than the profile 11 of the upper guide element 1, and which establishes a lower guide track 24 on which the chain 10 can slide.
  • the channel 3 is formed between the tracks 16 and 24 of the upper guide element 1 and lower guide element 2, respectively.
  • the lower guide element 2 can be provided with a series of lower flanges or ribs 21, which serve to laterally guide and retain the chain 10 in its return path, in correspondence with return guide elements 7 which will be described in detail below, to prevent the chain 10 from coming out of said return guide elements 7.
  • the lower guide element 2 comprises a plurality of notches 22 which serve to drain cleaning liquids during the processes of cleaning the chain 10 and the guide device 110. Therefore, when cleaning is performed, the cleaning liquid can go down through these openings or holes 22, which can be established between the lower guide element 2 itself and the profile 4 to which it is attached for example, or in an alternative configuration, in the lower guide element 2 itself. This allows easy draining of the cleaning liquids through the lower part of the guide device 110.
  • the lower guide element 2 can have an inclined surface that makes the cleaning liquids flow towards the openings or notches 22 in question.
  • the upper guide element 1 comprises a set of prolongations 19 with attachment elements 12" configured to be fitted in the openings or notches 22 of the lower guide element, as shown by way of example in Figure 11C .
  • the dimensions of the attachment elements 12" are substantially identical to or slightly smaller than the dimensions of the openings or holes 22, such that when the upper guide element 1 is attached to the base support, the openings or holes 22 prevent access or the entrance of dirt in the chain 10 through the openings or holes 22.
  • the prolongations 19 or the attachment of the attachment elements 12" in the openings or holes 22 and/or in the grooves 5' can also counteract the forces or motions perpendicular to the forward movement direction L of the chain 10, keeping the chain 10 in the established position.
  • This configuration of the lower guide element 2 can also serve for any embodiment and/or configuration of the invention, not only for the preferred embodiment.
  • the machine 100 can further comprise a fixing coupling 9 associated with each upper guide element 1 and with the base support, particularly with the profile 4 of the base support, to secure the attachment between the corresponding upper guide element 1 and the base support and to prevent them from becoming detached during a packaging process, such as the one shown by way of example in Figures 10 , 11A , 11B and 11C .
  • the upper guide element 1 can also comprise at least one attachment element 12' in the form of bolts, similar to the attachment elements 12, which in turn comprises a rod 12E and a head 12F.
  • the rod 12E is longer than the rods 12A of the attachment elements 12 and configured to secure the upper guide 1 by means of the fixing coupling 9.
  • the attachment element 12' furthermore carries out the function of an attachment element 12.
  • the fixing coupling 9 cooperates with the attachment element 12' to prevent the accidental detachment of the base support and the upper guide element 1.
  • the fixing coupling 9 comprises a body 9C, an articulation 9B and a grip 9A.
  • the body 9C preferably comprises a hole not shown in the figures (or groove), which is traversed by the articulation 9B (which corresponds to a rod, for example, and a head), the profile 4 in turn comprising a hole also for receiving the articulation 9B, the fixing coupling 9 thus being attached to the profile 4 by means of the articulation 9B.
  • the body 9C has rotational freedom with respect to the articulation 9B when the fixing coupling 9 is attached to the profile 4, and a user can cause this rotation by operating the grip 9A to release the attachment element 12' and to therefore be able to detach the upper guide element 1 from the base support.
  • the grip 9A can additionally operate a latch 9A' which is inserted in a hole 4' of the profile 4 once the fixing coupling 9 is in its lock position, thereby preventing the accidental opening of the fixing coupling 9, and therefore, of the upper guide 1.
  • One end of the fixing coupling 9 comprises a substantially U-shaped portion and serves to clamp the attachment element 12', the opening of the U-shaped portion being in the lower part.
  • the base support and the upper guide element 1 are attached to one another that attachment can then be secured, causing the substantially U-shaped end to clamp the attachment element 12', said end being arranged between the profile 4 and the head 12F of the attachment element 12'.
  • the central axis of the body 9C is substantially perpendicular to the inclination of the groove 5, thereby optimizing the function of the fixing coupling 9.
  • the length of the rod 12E is substantially identical to or slightly greater than the sum of the width of the profile 4 and the width of the fixing coupling 9, such that the head 12F of the attachment element 12' prevents the movement of the upper guide element 1 in the direction perpendicular to the forward movement of the band or strip of material, while at the same time the fixing coupling 9 assures the correct placement of the upper guide element 1 inside the groove 5 and prevents accidental detachment.
  • the upper guide element 1 is attached to the base support by means of at least one groove 5', although it is preferably attached by means of a plurality of grooves 5'.
  • the groove 5' is between the lower guide element 2 and the profile 4 of the base support and the upper guide element 1 comprises an attachment element 12" for cooperating with the groove 5'.
  • the groove 5' could be directly in the lower guide element 2.
  • the upper guide element 1 comprises a prolongation 19 such as the prolongation mentioned for the preferred embodiment, and an end of said prolongation 19 corresponds to the attachment element 12", the end of said prolongation 19 preferably comprising an attachment element 12" longer than the one shown in the figures and the groove 5' therefore being deeper.
  • the lower guide element 2 comprises a plurality of grooves 5' and the upper guide element 1 comprises a plurality of attachment elements 12".
  • the coupling between the upper guide element 1 and the base support can therefore be established directly between the upper guide element 1 and the lower guide element 2.
  • the upper guide element 1 can comprise a hook or equivalent element for securing the attachment with the base support, cooperating with said base support.
  • the groove 5' can be similar to the groove 5 of the preferred embodiment, the attachment therefore being performed by means of sliding, or a downward motion of the upper guide element 1 can be sufficient.
  • the upper guide element 1 further comprises a flange similar to flange 1A of the preferred embodiment, such that the upper guide element 1 stays in its position on one hand as a result of the groove 5" of the flange 1A and on the other hand as a result of the attachment between the groove 5' and the attachment element 12".
  • attachment elements 12 like those described for the first embodiment, or the associated elements or features, but they could also be included.
  • the machine 100 further comprises a fixing coupling for the same function as that carried out by the fixing coupling 9 of the preferred embodiment.
  • the upper guide element 1 can comprise a projection projecting from its upper part for example, and the fixing coupling cooperates with the projection to perform its function, just as the fixing coupling 9 cooperates with the attachment element 12' of the preferred embodiment of the invention.
  • the features of the projection can be similar to the attachment element 12' of the preferred embodiment, with the difference that its length does not have to take the width of the profile 4 into account.
  • the guide device 110 can comprise a flange similar to flange 1A of the preferred embodiment, with its groove 5" for cooperating with the profile 4.
  • the guide device 110 can comprise a plurality of upper guide elements 1 as shown by way of example in Figure 12 , located one after the other in the forward movement direction L, instead of a single upper guide element 1. Given that the course of the chain 10 while driving the band or strip can be considerable, the guide device 110 can many times be very long, for example ten meters or longer. Several sectors of guide devices 110, which can each comprise a fairly long profile, for example five meters or longer, can be used for that purpose.
  • the upper guide elements 1 i.e., for example, when they are removed from the base support and when they are again fitted in or attached to the base support, it may be convenient for the upper guide elements 1 to be relatively short (for example, in the order of one meter).
  • the lower guide elements 2 can be more or less fixed, for example, they can be an integral part of a profile or be attached to a profile by means of screws, nuts, bolts, or the like. They can be long since they generally do not have to be handled, which can facilitate continuity.
  • the upper guide elements 1, intended for being disassembled for cleaning operations may frequently be handled so it may be convenient for them to be shorter than the lower guide elements 2.
  • the upper guide elements 1 can be separated from one another by a specific gap 6, preferably a few millimeters or centimeters in size, allowing the movement of one of the upper guide elements 1 with respect to the other to disengage or detach the upper guide element 1 from the base support, especially when there is an inclined groove 5 or 5'.
  • the gap 6 between the different upper guide elements 1 allows a fitting or interlocking motion of each upper guide element 1 for becoming disengaged or detached from the base support, i.e., the different upper guide elements 1 can be gradually interlocked and unlocked individually, without the motion of an upper guide element 1 being prevented by an adjacent upper guide element 1.
  • the guide device 110 can additionally comprise at least one return guide element 7, preferably a plurality of return guide elements 7, arranged below the lower guide element 2 and configured to support the chain 10 by sectors during its return motion.
  • the chain does not drive the band or strip, so no guiding is required to counteract transverse forces.
  • certain guiding or support of the chain 10 may be convenient, for example, to prevent noises, but it may be sufficient for this support to be by sectors.
  • the return guide elements 7 can be arranged in specific positions corresponding to a welding station 103, a forming station 102 and a transverse cutting station 106.
  • Figure 13 shows a return guide element 7, which can likewise comprise a machined, extruded or molded profile 71 with a lip 72 for retaining the chain 10.
  • the return guide elements 7 are shorter than the upper guide elements 1 and the lower guide elements 2. Attachment means such as screws 14, for example, are used to attach the return guide elements 7 to the base support, particularly to the profile 4 of the base support.
  • the lower guide element 2 comprises a machined, extruded or molded profile 23 that is longer than the profile 11 of the upper guide element 1, and which establishes a lower guide track 24 on which the chain 10 can slide, as has been mentioned for the preferred embodiment.
  • the lower guide element 2 can be provided with a series of lower flanges or ribs 21 and openings or holes 22.
  • Figure 11B shows the attachment of the element lower guide 2 to the profile 4 by attachment means, such as screws 13, for example, traversing the lower guide 2 and the profile 4 and screwed into a blind nut 13A with washers 13B.
  • attachment means such as screws 13, for example, traversing the lower guide 2 and the profile 4 and screwed into a blind nut 13A with washers 13B.
  • the blind nut 13A and washers 13B would be suitably replaced.
  • both elements, the lower guide 2 and profile 4 can be part of a single element.
  • the elements of the upper guide 1, lower guide 2 and return guide 7 can be made of a plastic and/or polymer material and can be molded and then fixed to the profile 4, for example.
