    [0002] Orbital wrapping machine
    [0004] Technique sector.
    [0006] The present invention refers to an orbital wrapping machine, applicable in the packaging sector and which has adequate technical characteristics to automatically place and fix around the product or products to be packed an adhesive tape, or a tape with hot melt adhesive or hot melt .
    [0008] Prior state of the art
    [0010] Currently, different machines applicable in the packaging of very diverse products are known.
    [0012] For example, elastic thread tying machines are known, mainly used in knotting grouped vegetables, and which work with calibrated thread of one or more ends, performing the knotting of the thread, previously arranged around the product. These tying machines require a complex head for knotting the thread and cutting the elastic thread,
    [0014] Seal tying machines are also known which have an adhesive tape extended between a swing arm carrying a tape dispenser reel and a clamp for the opposite end of the tape, so that when pushing the product to be taped against the adhesive side of the tape, it forms a single loop around the product, two end portions of the tape sticking together, which once cut are joined and form a double section that protrudes laterally from the loop.
    [0016] The banding machines, also known, have a frame in which a band of material is inserted forming a single loop that wraps around and closes around the product to be bundled. These balers, like the bundlers mentioned above, form a single loop or loop around the product.
    [0018] Orbital wrapping machines are also known on the market that apply a stretch film band around the product to cover it externally, forming a external protection and to hold the product together. These types of machines are mainly used to wrap palletized loads and have a rotating base on which the product to be wrapped is placed and a rotating head carrying a roll of stretch film that moves around the load and vertically along The same to cover the entire lateral surface of the product with film.
    [0020] Currently, in the e-commerce sector, there is a growing need to package products of a relatively small size in order that they remain together and that said permanence is maintained during their transport and distribution.
    [0022] The solution currently used to cover this need is manual sealing with adhesive tape, so the result obtained depends on the skill and disposition of the operator in charge of the product packaging in each case, there is no certainty that the product packaging is the right one to prevent it from coming loose during the transport and distribution of the product.
    [0024] Explanation of the invention
    [0026] The orbital wrapping machine object of this invention has a series of technical characteristics that allow its adaptation to work with both adhesive tape and tape provided with a hot melt adhesive, and whose purpose is to make a fast, resistant and safe wrapping of the product by automatically applying several overlapping layers of tape over the same area of the product
    [0028] According to the invention, this orbital wrapping machine comprises a frame provided with a hole for positioning the product to be taped, a rotating ring carrying a ribbon reel being arranged on one side of said frame and around said hole. taping cycle applies several wraps of tape around the product to be taped.
    [0030] This machine includes, in addition to the rotating ring, a series of mobile elements whose operation is controlled by a programmable automaton, automatically or semi-automatically wrapping the product.
    [0031] It should be mentioned that the term product is used regardless of whether it is a single unit or several grouped units, for example profiles, slats, or any other type.
    [0033] This machine comprises a series of mobile elements that will be described below and whose purpose is to perform different functions during the taping cycle of a product: holding the free end of the tape coming from the reel, until the taping of the product begins. and said free end is unable to move; the subsequent application of successive wraps of tape around the product making its wrapping; the separation or distancing of the product from the last turn of the tape that remains attached to the reel, and finally the cutting of the last turn of the tape distanced from the product, holding the free end of the tape coming from the reel, until starting a new taping cycle.
    [0035] These elements comprise a first roller that is prevented from turning and mounted on the frame with the possibility of movement between: an inoperative position in which it is kept outside the wrapping path of the belt, and an operative position in which it is arranged within said path. . In this operating position, the first roller is kept spaced in a radial direction from the product to be taped and forms a support for the last turn of the taping tape applied to the product, to subsequently allow the automatic cutting of said tape, without affecting or damaging the taping. applied on the product.
    [0037] The machine further comprises an arm movable between: an inoperative position, outside the wrapping path of the belt, and an operational position within said path. In their operative position, the movable arm and the first roller form a clamp for holding the tape that still remains attached to the reel once the product has been taped.
    [0039] This machine comprises a blade movable between: an inoperative position, outside the wrapping path of the tape, and an operative position in which it cuts said behind the first roller, separating the tape from the tape that remains attached to the reel.
    [0041] When this cut is made, after taping the product, the free end of the tape coming from the reel is pinched by the first support roller and the movable arm, remaining held in this position until a new taping cycle begins.
    [0043] Advantageously, the first support roller and the movable arm are mounted on respective rotating axes, parallel to the plane of the rotating ring, and arranged in a plane perpendicular to the aforementioned plane of the rotating ring, being actuated in a synchronized manner by the programmable automaton during the cycle. taping of the product.
    [0045] The invention provides that this taping machine can work with flexible tapes of different materials and, in particular, both with adhesive tapes and with tapes provided with a heat-activatable adhesive (hot melt); incorporating in each case suitable elements for the type of tape to be used
    [0047] Specifically, in one embodiment of the invention, the machine comprises a second roller, in this case freely rotating, to support the last turn of the tape applied to the product to be taped, when the machine works with adhesive tape. This second roller is arranged parallel to the first roller and moves together with said first roller between the operative and inoperative positions.
    [0049] The free rotation of this second roller allows that at the beginning of the taping cycle, with adhesive tape and once the clamping arm has been moved towards the inoperative position, the free end of the adhesive tape can be released more easily from the two rollers. support for.
    [0051] In another variant of embodiment, suitable for working with non-adhesive tape, for example paper tape provided with a heat-activatable adhesive, and ensuring that the end of the tape is kept in the initial taping phase in a correct position, it has been Provided that the machine incorporates a movable clamp to hold said free end of the tape against the taping product during the start of taping and until said free end is held at least for the first turn of taping.
    [0053] In this case, taking into account that the tape is not adhesive, to fix the tape on the product, the machine comprises means for activating the adhesive material of the tape and fixing the tape around the product, before cutting the tape. the last turn of the tape.
    [0055] According to the invention, the means for activating the adhesive material of the non-adhesive tape They comprise a heating plate mounted on the frame with the possibility of movement between an inoperative position in which it is kept away from the taping applied to the product, and an operating position in which it approaches a zone of the taping and activates the adhesive in said zone.
    [0057] In an alternative embodiment, said means for activating the adhesive comprise a sonotrode movable between an inoperative position in which it is kept away from the tape applied to the product, and an operative position in which it approaches an area of the tape and activates the adhesive in said area.
    [0059] In any of the aforementioned embodiments, provision has been made for the rotating ring to be advantageously arranged in a vertical plane to facilitate the taping of elongated products, allowing the implantation of the interleaved machine in an area where said products pass through.
    [0061] With the aforementioned characteristics, this machine provides a series of advantages, among which it is worth highlighting:
    [0063] - robust and reliable wrapping of the product with adhesive tape or with a tape carrying an adhesive that can be activated by heat (hot melt).
    [0064] - Possibility of working with paper-based tapes and biodegradable adhesives, defining a sustainable and environmentally friendly packaging system, maintaining high taping performance.
    [0065] - High application speed.

    [0100] Detailed exposition of embodiments of the invention.
    [0102] In the embodiment shown in Figures 1 to 6, the wrapping machine of the invention comprises a frame (1) provided with a hole for positioning the product (P) to be taped, being arranged on one of the sides of said frame ( 1) a ring (2) made possible to rotate with respect to said frame (1) and mounted on it by means of guide rollers (21) and a drive roller (22) driven by a servomotor (not shown) located on the opposite side of the frame and controlled, like the rest of the mobile elements of the machine, by a programmable automaton.
    [0104] The ring (2) has a reel holder (23) for mounting an adhesive tape (31) used in the embodiments of Figures 1 to 6, or a tape (32) with hot melt adhesive used in the embodiments. of Figures 7 to 10.
    [0106] In the example shown in Figures 1 to 6, the taping machine comprises a first roller (41) that is unable to rotate, and a second roller (42) that rotates freely and parallel to the first roller (41). Both rollers (41,42) are arranged in a plane perpendicular to the plane of the ring (2) and are mounted on a rotating shaft (43), parallel to the plane of the ring (2). The rotation of the shaft (43), controlled by the programmable automaton, causes the displacement of said rollers (41; 42) between an inoperative position, outside the wrapping path described by the adhesive tape (31) during taping of the product (P), and an operative position within said wrapping path.
    [0108] The movable arm (5) is arranged in the same plane as the rollers (41,42) and mounted on an axis (51), parallel to the axis (43) and which, when actuated by the automaton, causes the displacement of the movable arm (5) between an inoperative position, outside the enveloping path of the adhesive tape (31), and an operative position in which it contacts laterally with the first roller (41) to hold the end of the adhesive tape (31) prior to the start of the taping.
    [0110] In this embodiment, the machine comprises a blade (6) for cutting the adhesive tape (31) once the product (P) has been taped. Said blade (6) is arranged in a plane parallel to that of the rollers (41,42) and between said rollers and the positioning area of the product (P) to be taped.
    [0112] The blade (6) is mounted on an axis (61) parallel to that of the rollers (41,42) and which, when actuated by the automaton, causes said blade (6) to move between an inoperative position located outside the trajectory wrapping of the adhesive tape (31), and an operative position, within said path.
    [0114] As shown in figure 2, in a phase prior to the start of taping the product (P), the end of the adhesive tape (31) is held by the movable arm (5) against the first roller (41), and the blade (6) in an inoperative position.
    [0116] When the taping starts with the rotation of the ring (2), the adhesive tape (31) adheres to the product (P) and the rollers (41, 42) and the movable arm (5) are moved towards the inoperative position allowing the application of several turns of adhesive tape (31) on the product (P), as shown in figure 3.
    [0118] During the application of the last turn of adhesive tape (31) around the product (P) to finish the taping, the rollers (41, 42) move towards the operative position so that the end of the tape that remains attached to the coil is kept away from the taped product (P), as shown in figure 4.
    [0120] Once the taping is done, the ring (2) stops rotating and the movable arm (5) is positioned in the operative position represented in figure 5, pinching the adhesive tape (31) against the first roller (41), said tape being adhered to the rollers (41,42).
    [0122] Finally the shaft (61) of the blade (6) rotates, moving it towards an operative position in which it cuts the adhesive tape (31) behind the rollers (41,42) as shown in figure 6 , the blade (6) being subsequently withdrawn towards the inoperative position, and the end of the adhesive tape (31) of the reel retained in the same position of figure 1, waiting for a new taping cycle to begin.
    [0124] In the example shown in Figures 7 and 8 a variant embodiment of the machine is shown which, while maintaining the same structure of the previous embodiment, presents suitable characteristics for working with a tape (32) with hot melt or hot melt adhesive.
    [0126] In this embodiment, given that the tape (32) is not adhesive, to prevent the end of the tape (32) from slipping over the product (P) during the start of wrapping, the machine incorporates a plunger (7) that presses said end of the tape (32) against the product (P) as shown in figure 7, until at least the first turn of tape (32) applied on the product (P) steps on the end of said tape preventing its movement .
    [0128] In this case, the machine incorporates means (8a, 8b) for heat activation of the adhesive material of the tape (42).
    [0130] In the embodiment shown in Figures 7 and 8, said adhesive activation means (8a) comprise a heating plate (81) mounted on the frame (1) by means of a shaft (82) that causes its rotation between an inoperative position. , represented in figure 7, in which said heating plate (81) remains spaced from the tape applied on the product (P); and an operative position, shown in Figure 8; in which it approaches an area of the taping and activates the adhesive of the tape, ensuring the immobilization of said taping by activating the adhesive of the tape (42).
    [0132] In this embodiment, the cutting of the tape (32) once the taping is finished and the adhesive of the tape (42) is activated is carried out by means of a blade (83) that moves together with the heating plate (81) during the rotation. shaft (82).
    [0133] In the embodiment shown in Figures 9 and 10, the means (8b) for activating the adhesive of the tape (32) comprise a sonotrode (84) which, like the heating plate (81) of the previous embodiment, It is mounted on the frame by means of a rotating shaft (82) in charge of moving it between the inoperative position shown in figure 9 and the operative position shown in figure 10.
    [0135] In this case, the cutting of the tape (32), once the taping has been carried out and the adhesive has been activated, is carried out by means of a blade (83) that moves together with the sonotrode (84) between the operative and inoperative positions, by means of the shaft rotation (82).
    [0137] Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the elements described may be modified, as long as this does not imply an alteration. of the essential characteristics of the invention that are claimed below.
