Description

DESCRIPTION

Cash closing system and procedure

Technical field

The invention relates to a box closure system, in particular for boxes for the pharmaceutical sector which, in technical jargon, are referred to as cardboard boxes and are closed with a pressurized closure panel. The invention further relates to a respective box closure plant that allows simultaneous closure of the boxes on both sides. The box closing system and the plant allow the closing of boxes with closing panels located on opposite sides of the box, where both closing panels are a continuation of the same side of the body of the box and also the closing of boxes with panels of closure that are located on opposite sides of the box but whose closure panel is the continuation of one side of the body of the box, while the other closure panel is the continuation of another side of the body of the box. A respective cash closing procedure is also proposed.

State of the art

For the closing of boxes, in particular of folding boxes of paper or cardboard, comprising the folding of dust-proof closing side flaps and the insertion of the closing flap of a closing panel in the body of the box and the subsequent pressure closure, different procedures and corresponding devices are known, which require, with the change of the type (for example, change of the position of the closure panels) and the format / size of the box, a change and / or a adjustment of the folding and insertion tools, which results in a considerable waste of time and the need to provide complex systems for adapting the closing device to the box format.

US 6,598,380 B1 describes a box closure system and a method that uses a lever system to close the box, while Japanese document JP H08 169404 A describes the combination of a retention device and a pusher to close a box and European patent application EP 1717 147 A1 indicates for this purpose a plunger with tongue. EP 1873063 A2 describes a box closure system comprising successively folding means for folding a closing flap with respect to the box with a shaped bar, a first rotating element for folding a complementary final flap with respect to the flap of closing, a second rotating element for the insertion of the complementary final flap in the mouth of the box, a third rotating element for locking the complementary flap with closing tabs, thus providing a complete closure of the box, and a transport system from the box.

Description of the invention

The object of the invention is to overcome the disadvantages described above and propose a cash closing system and a procedure that requires, with the change of the cash type, less changes and / or adjustments of the cash type and less corresponding adjustment means in comparison with the state of the art. Other objects of the invention become apparent from the description of preferred embodiments of the invention.

In a first aspect of the invention, the object is achieved by a box closure system as defined in the first claim, that is, by a box closure system comprising:

(a) an entrance guide system suitable for folding a closing flap of a box not yet closed towards the body of the box;

(b) downstream of the entry guide system, a folding disc suitable for folding the closing flap of the closing panel along a folding line and for placing the closing flap on the case body;

(c) downstream of the folding disc, a guide element suitable for spacing the closure flap of the case body and forcing the spaced closure flap of the case body to form with respect to the remaining part of the closure panel a angle less than 90 °;

(d) downstream of the guide element, an insertion roller for pushing the closing flap into the body of the box such that the remaining part of the closing panel closes the box and forms one side;

(e) downstream of the insertion roller, a closing roller to close the pressurized housing; Y

(f) a transport system for transporting at least one box from at least the entrance guide system, to the folding disc, to the guide element, to the insertion roller, to the closing roller,

where

(i) said entry guide system comprises an obliquely inclined plane with respect to the direction of transporting the box where the closing panel can be passed in front of the obliquely inclined plane and, in contact with it, will be raised or lowered to cover the opening of the box during the passage;

(ii) the surface of the folding disc intended to come into contact with the closing flap of the box closing panel is parallel to the side of the box on which the closing flap will be placed;

(iii) the guide element comprises

(I) a first conformation that defines a curved path that pushes the closing flap with the passage of the box along said first conformation away from the body of the box; Y

(II) a second conformation defining a height limitation that folds the closing flap so that an angle of less than 90 ° is formed with respect to the remaining part of the closing panel; and where

(iv) the insertion roller and the closing roller are arranged such that its axis of rotation extends perpendicularly to the side of the box on which the folding disc can place the closing flap and in such a way that the part of the closing panel, which forms one side of the box, passing in front of the respective insertion and closing rollers is partially in contact with the lateral surface of the rollers.

The proposed box closure system allows you to close boxes with closure panels in different positions and boxes that have different sizes. Advantageously, in particular, the entry guide system and the insertion roller and the closing roller are, thanks to their flat and cylinder extension in the case of rollers, capable of performing their action independently of the extension of the closing panel. For this purpose, advantageously, the insertion roller and the closing roller are arranged in such a way that there is a tangential contact with the front side of the box, that is, with the closing panel that closes the box forming the front side. . The front side is a plane tangential to the lateral surface of the rollers.

Preferably, the obliquely inclined plane approximates the position of the front side and then advantageously ends in a flat sector parallel to the front side so that the closure panel can be held against the body of the case.

In addition, the extensions of the first conformations of the guide element are preferably chosen with dimensions such that the closing flap, regardless of its extension, is spaced from the body of the box so that its front edge is essentially flush with the front edge on the side of the box where the closing flap was supported. Having the front edge of the closure flap essentially flush with the front edge of the side of the box where the closure flap was supported, the second conformation that limits the height does not have to adapt to different sizes of the closure flap if it is made in such a way that it presses at least against the front of the closing flap. Advantageously, the flat sector of the entry guide system, the final part of the first conformation (which defines the position of the front edge of the closing flap after being spaced from the body of the box), the second conformation and the perimeter of the Insertion roller and closing roller are arranged along a line that forms the fixed (imaginary) edge so that the side of the box is closed. This allows the box to be transported with a simple translation movement, without having to make any other position changes compared to the individual closing components within the box closing system.

Advantageously, the position of the front part of the box along its longitudinal extension transversely to the direction of travel, therefore, does not change. This facilitates the fixed positioning of the elements shown under points (a) to (e) with reference to the position (distance) with respect to the front side of the box.

These considerations mean that the different sizes of the body of the box have no relevance from the functional point of view of the system, except for the height adjustment of the folding disc and the guide element to take into account the different heights of the boxes and / or of different positions of the closing panel that must be brought up or down to the body of the box. The height refers to the position or extension along the direction of the rotation axes of the folding disc and / or the insertion and closing rollers.

The first conformation advantageously provides a curved pattern in the transport direction (as can be seen in the exemplary form in Figure 1) that pushes the flap moving with its front edge along the curvature away from the body of the box. Advantageously, the second conformation includes, for example, introduced by a second entry guide system (as can be seen in the exemplary form in Figure 3), a protuberance with respect to the plane of the side where the closing flap is supported by pressing thus on the closing flap to create between the closing flap and the remaining part of the closing panel an angle less than 90 ° (as seen in the exemplary form in Figure 4). In the described variant, the guide element is supported by the second conformation, respectively, on the side where the closing flap is folded and on the closing flap itself.

Preferably, the entry guide system involves a division of the obliquely inclined plane, which performs specular inclinations along the dividing line, to allow a closing panel to fold from the part bottom or from the top towards the body of the box. This is particularly advantageous to take into account the fact that the boxes on the market are of two types with respect to the position of the closing panel. To better illustrate this difference in the boxes, reference is made to Figures 7a and 7b, which represent boxes of the prior art of both types. In Figure 7a, the body of the box, which is composed of an upper side and a lower side and two lateral sides, is called 5a . The box 4a has two closing panels 2a with a closing flap 8a each. The closing panels are in one case the continuation of the upper side and in the other case the continuation of the lower side. The reference number 6a indicates dustproof closing flaps, while the reference number 7a indicates small cuts between the closing flap 8a and the remaining part of the closing panel 2a that they serve, when closing the box 4a , to wedge the panel with the corresponding shaped edges of the dustproof closure flaps 6a . In Figure 7b, on the other hand, the body of the box, which is composed of an upper side and a lower side and two lateral sides, is called 5b . The box 4b has two closure panels 2b with a closure flap 8b each. The closing panels are in both cases continuations of the lower side of the box. The reference number 6b indicates dustproof closing flaps, while the reference number 7b indicates small cuts between the closing flap 8b and the remaining part of the closing panel 2b that are used, when closing the box 4b , to wedge the panel with the corresponding shaped edges of the dustproof closure flaps 6b .

In a preferred embodiment of the invention, the folding disk is height adjustable, the height being defined by the position of the folding disk along its axis of rotation. This height variability allows folding a closing flap on the upper side of the box if the closing flap is closed by lifting it up from the bottom, or allows folding the closing flap on the lower side of the box when the panel Closing closes by lowering down from the top, considering the two types of boxes in the market. Alternatively, the adjustments that take into account the above differences can also be produced by moving the case with respect to the folding disc.

Always in terms of different positions of the closing panel and height adjustments, an additional advantageous variant of the closing system provides that said guide element comprises a second set of a first and a second extension conformation with a mirror image with respect to the first set of a first and a second conformation that is adjustable in height to approach a set of conformations or another in the upper or lower part of the box, respectively. Optionally, the guide element includes, for each set of conformations, a stop protrusion that limits the reopening of the box to a certain degree or the distance of the closing flap from the body of the box at a certain distance. Said butt protrusions can be, for example, stems showing an end towards the closure panel.

Advantageously, the guide element is a U-shaped profile where the conformations are located respectively on the internal lateral sides of the profile and where the lateral sides of the profile are respectively placed outside the box on the upper and lower sides of the boxes and where the front side of the box to be closed points towards the bottom of the profile.

In a preferred embodiment of the invention, the closure roller is provided on the side surface of a plurality of protuberances that preferably have elastic characteristics. It has been shown that the "hammering" action of the individual protuberances results in a good snap closure. Pressure closure refers in particular to boxes with a cut between the closure flap and the remaining part of the closure panel to wedge the cuts with relative bevels of the dustproof closure flaps.

In another advantageous variant of the invention, the insertion roller and the closing roller are wound by a belt, where at least one additional roller is optionally present within the belt. The additional roller or a series of additional rollers make it possible to manage, according to the principles known by the expert, the movement of the belt and the rollers wound therein.

The box closure system and the relative plant and the procedure described hereafter are particularly suitable for closing boxes with pressurized closure panels comprising a cut between the closure flap and the remaining part of the closure panel and, therefore, therefore, advantageously, also dustproof closure flaps.

The case closure system can be advantageously combined with a dustproof closure flap closure system, placed upstream.

In a variant of the invention, the insertion roller includes a groove in the side surface. This slot simplifies the grip of the closure panel and then pushes it against the body of the box by simultaneously inserting the closure flap into the body of the box. It should be noted that the position of the groove with respect to the incoming closure panel requires consideration of the phase.

In an advantageous variant of the invention, the transport system of the box closure system according to the invention comprises (a) a first support plane; and (b) a second support plane that is orthogonal to the first support plane; where the first support plane comprises a first sector suitable for reversibly fixing a box by adhesion; and wherein said box is bearable or supported with a first side that preferably does not correspond to a closing side of the box in said first support plane and which can be fixed or reversibly fixed by adhesion with said first side in said first sector and where said box is bearable or supported with a second side, which it is adjacent to said first side and which preferably does not correspond to a closing side of the box, in said second support plane. Said transport system is described in Italian application No. 102016000082727, on behalf of the same applicant. Said system is particularly suitable for use in the box closure system according to the invention, since it releases the front part, the upper part and a side part of the box so that the box can be introduced without particular obstacles or fixed edge displacements of the traditional transport systems in the entry guide system with the subsequent application of the folding disc, the guide element and the rear rollers that require freedom to act on the upper front and front side of the box. The first and second support planes serve as the so-called fixed edges of the system. Its orthogonal position allows to place a box with orthogonal sides in a defined position. Even such a transport system does not require adaptations to any dimensional change (in particular changes in the width and height) of the box, thus supporting the purpose of the invention to reduce the settings by changing the type of box. Preferably, the boxes are of the type that in the technical jargon is known as cardboard boxes. Preferably, the first support plane is essentially parallel to the forward direction of the transport device.

In a highly preferred embodiment of the invention, the second support plane comprises a second sector suitable for reversibly adhesion fixing said second adjacent side. The presence of two "adhesive sectors" helps create an "orthogonal configuration" of the box because one side of the box that is not only supported on a support plane, but also exerts an adhesive force on it, forces both sides adjacent to the box in an orthogonal position that is necessary for closing and / or filling. In the case of the presence of two suitable sectors for adhesion fixing one side of the box in a reversible way, the box can be fixed or reversibly fixed with the second side, which is contiguous to the first side and which preferably does not correspond to one side of closing the box in said second sector of said second support plane.

Advantageously, said sectors that are suitable for reversibly fixing one side of the box are essentially on the support surface of the support plane and do not protrude therefrom. In a further variant of the invention, the first sector and / or the second sector are provided with an adhesive means, which is selected from a suction means, a surface suitable for friction fixing materials and a surface suitable for fixing materials by glue. . In other words, the suction means can be defined as a subpressure or a vacuum. In the case of the suction means, which is preferable, the sector suitable for fixing a side of the housing by adhesion is, for example, represented by a recess or opening in the support plane, which comprises a connection to a device for suction that, in case of closing the recess or opening with a box resting on it, allows to create a vacuum inside the recess / opening, thus exerting an adhesion force on the box. Advantageously, sealing systems can be provided to improve the vacuum. When filling the recess / opening with a gas, which in the simplest case is air, preferably always through the same suction device, the adhesion is suspended and the box can be removed from the transport device, such as tilting the transport or pushing with a pushing element. The suction means have the advantage of not carrying the adhesive force quickly, as is the case, for example, with joining materials that, with repeated use, lose their adhesive force due to material shedding and / or dust deposit. Friction fixation can occur, for example, with silicone materials.

Preferably, the box comprises two closing sides. The transport device according to the invention is particularly suitable for boxes with two closing sides, in particular with two open closing sides, since the combination of two orthogonal fixed edges with one or, more preferably, two sectors suitable for reversible fixing by adhesion of two adjacent sides of the box allow an "orthogonal configuration" also of boxes that have two open sides, which can be easily deformed creating a box configuration that, in section, looks like a parallelogram instead of a rectangle.

Advantageously, the transport device according to the invention is provided or associated with at least one additional support that represents the continuation of one of the support planes to allow the support surface to be increased. Said support can be made, for example, of a plurality of plastic nodes, which can be attached to a conveyor belt or a toothed belt conveyor platform where the transport device is also secured.

In an advantageous alternative of the box transport device according to the invention, one or each of the support planes may comprise more than one sector capable of reversibly fixing one side of the box by adhesion. A plurality of sectors increases the security of fixation and could be especially useful in case of transport of large boxes. The person skilled in the art can easily identify the best design of the "adhesion sectors" in the support drawings. In the case of individual sectors, a more central position will be preferable, while in the case of a plurality of sectors it will be more advantageous to have an arrangement that guarantees fixing points that are evenly distributed in the support plane and are not concentrated in a area.

Another aspect of the invention relates to a box closing plant comprising two box closing systems according to the invention, where a box closing system is placed opposite each other with the respective individual components corresponding to each other to allow the contemporary closure of two opposite sides of the box. Alternatively, the second closing system may also be arranged downstream or compensated with respect to the first closing system. In another additional alternative, the closing of the second side is done by passing the box with only one side closed for the second time through the box closing system, for example, after having introduced a product in the box between one step and the other.

A final aspect of the invention relates to a cash closing procedure comprising the following steps in the given order:

(i) the provision of a cash closing system according to any one of claims 1 to 8 or a cash closing plant according to claim 9;

(ii) raising or lowering the closing panel of an open box with said entry guide system, such that the panel covers the opening of the box;

(iii) folding the closing flap of said box closing panel with said folding disk, so that the flap is placed on the body of the box;

(iv) the spacing, by said guide element, of said closure flap of the case body and the folding of the closure flap with respect to the remaining part of the closure panel in the direction of the body of the case of such so that the closing flap and the remaining part of the closing panel of the box form an angle less than 90 °;

(v) inserting said closure flap by the action of said insertion roller against the closure panel in said case body; Y

(vi) the pressure closure of said box by the additional action of said closing roller on said closing panel.

The succession of the previous phases represents, in comparison with the state of the art, in particular with the use of the closing system / plant according to the invention, few system adjustments when changing the format (position of the closing panels, size) of the boxes to close. Advantageously, during the box closing process according to the invention, the box is transported from one phase to the next and during the phases listed by means of a transport system as defined in claim 6 or one of its embodiments described above.

Transportation can take place alternately, as well as on an ongoing basis. In variants of the invention, the transport system may be a horizontal or vertical transport system.

The transport is advantageously carried out with the support and reversible fixing of the box with said first side, which preferably does not correspond to a closing side of the box in said first sector in said first support and support plane with said second side, which it is adjacent to said first side and which preferably does not correspond to a closing side of the box, in said second support plane of said transport device; with the transport of said box for a certain section and precisely from the entrance guide system to the closing roller or during the phases from the lifting or lowering of the closing panel in the body of the box. The removal of said box from the transport device can be added after fitting the closure panel.

The procedure allows the transport of boxes of different sizes without having to adjust the transport device after changing the type or size of the box to adapt it to the new size, as is necessary in the state of the art transport systems. In addition, it does not obstruct the positioning of boxes of different types, so that the closing side for each type of box is always in the same position in the transport device.

Advantageously, the box closure method according to the invention comprises, after phase (vi), the change of the type or size of the box (i.e., the replacement of boxes used so far by boxes of other sizes) and then the repetition of the phases from (i) to (vi), possibly adjusting, if necessary, the height of the folding disc and the position of the guide element to take into account the type and size of the closing panel.

Preferably, the box packing plant according to the invention also includes a box filling unit and / or a unit for closing the dustproof closure flaps.

A final aspect of the invention relates to the use of the box, plant and method closure system according to the invention in the pharmaceutical sector for the transport of boxes for pharmaceutical or similar products or in the cosmetic sector for the transport of boxes for cosmetic products . An alternative refers to the use in the food sector for the transport of food boxes.

The features described for one aspect of the invention can be transferred mutatis mutandis to the other aspect of the invention.

Such objects and advantages will be better highlighted during the description of preferred embodiments of the invention, given by way of example and not limitation. Variants of the invention are the subject of the dependent claims.

Description of preferred exemplary embodiments

Figure 1 is an exemplary embodiment of the box closure system according to the invention. The closure system is divided into five areas. Area A corresponds to the area where the closing panel 2 of the box 4 is raised by an entry guide system 6 . The box 4 moves with the closing panel 2 extended and open in the direction of the arrow a and enters the zone A of the closing system. In area A, the closure panel 2 is the system input guide 6 which is represented by an obliquely inclined plane with respect to the forward direction which, in contact with the closure panel 2, causes the panel closure rises in the direction of the body of the box 4 so that the closure panel 2 is supported in the opening of the box 4 . The box 4 advances in its trajectory and reaches the area B where the closing flap 8 of the closing panel 2 of the box 4 is folded by the action of the folding disc 9 on the body of the box 4 . Box 4 then reaches area C dedicated to the reopening of box 4 . A guide element 10 is provided with a suitable conformation for decoupling the closing panel 2 from the body of the box 4 in a first section and for folding the closing flap 8 at an angle less than 90 ° with respect to the rest of the panel of close 2 . The curved path of a first conformation of the guide element 10 shown in Figure 1 forces the closing flap that passes with its front edge along the curved line to separate from the case. In a second section, a second conformation that is introduced by a second inlet guide (visible inclination in Figure 2 in the guide element 10 ) presses with a protrusion 11 that acts as a height reducer in the closing flap 8 . When the closing flap 8 reaches the area D , the box 4 finds, in its forward movement, an insertion roller 12 that pushes the closing panel 2 with the closing flap 8 inside the body of the box 4. In the exemplary embodiment shown, the insertion roller 12 has a groove or recess 14 which, however, is not necessary and can also be omitted. The recess 14 may be useful to have a better "grip" of the closure panel. When passing over the insertion roller 12 , the box 4 closes. At the end of the closing path, in area E , the closed box (temporarily) passes over a closing roller 16 provided with rubbery bumps 18 that give small strokes to the closing panel 4 to completely close the pressurized box 4 .

Figure 2 shows the closure system of Figure 1 in a side view; Compared to the view in Figure 1, the system is shown turned 90 °. On the left is the box 4 arranged in a transport device 20 located on a conveyor platform 22 , better illustrated below with reference to Figure 6. Within the area A , the entry guide system for raising the panel can be seen. close to the body of the box 4 . The representation is to speculate with respect to line b to take into account that the disk 9 can be adjusted in height to assume different positions between positions 9a and 9b to take into account the closing of boxes with "bottom-up" closure shown in figure 7b or "top-down" closure, as shown in figure 7a and different box height sizes (area B ). For the same reason, the representation is also specular for the input guide system 6 and the guide element 10 .

The concept of changing the height of the disk 9 in positions 9a to 9b in the direction of the double arrow c is repeated in Figure 3, which shows how the disk 9a bends over the closing flap and on the case body 4 . In a variant with a closure panel located on the bottom side of the case, the disc would push the closure flap from below ( 9b ) against the body of the case.

In Figure 4, it should be taken into account that the guide element 10 is provided with the beveled geometry of a step-shaped conformation 11 which allows the closing flap 8 to be pressed at an angle less than 90 ° with respect to the rest of the box, while the stop protrusions 13 keep the closure panel 2 in a position that is not too far apart from the body of the box 4 . In a variant with a closure panel that is located on the lower side of the box, the guide element would be raised to be supported with the lower conformation on the lower side of the box 4 .

Figure 5 shows another exemplary embodiment of the folding disc 9a and 9b of Figure 3, designated respectively with 109a and 109b , where the disc has bevels 24 at the edges to facilitate grip and flexion of the closing flap under the folding disc .

Figure 6 shows in a sectional view a box transport system 20 mounted on a toothed belt conveyor platform 22 . Each transport device 20 is provided with two orthogonal support planes 26a and 26b each serving as a fixed edge of the system. Each support plane 26a and 26b comprises a sector 28a and 28b , respectively, capable of reversibly fixing an adhesion box which, in the present case, comprises a suction system 30 . Such systems can be openings, for example, in the form of a suction cup, into which a small channel 32 emerges . The small channels 32 of both sectors suitable for fixing a box by adhesion are in communication through a connection channel 34 . Through an opening 36 , which is in communication with the system of channels 34 and 32 , a vacuum can be applied by means of a connection to a suction device (not shown).

In each represented transport device 20 a box 4 is provided, supported on two adjacent sides 42a and 42b by two support planes 26a and 26b and where it is held in position and in "orthogonal configuration" (the corners of the box sections they are rectangular) by orthogonal fixed edges (support planes 26a and 26b ). Then, the box is secured by applying a vacuum through the suction system 30 in the recesses 38 in the support planes 26a and 26b comprising the suction system 30 and which are closed by the box located above said support planes 26a and above the recesses 38 with a suction system 30 , where the recesses 38 correspond to the sectors that are suitable for reversibly fixing the supported side of the box by adhesion. The box 4 also supports other supports 40 that are arranged in the toothed belt conveyor platform 22 to form the continuation of the support plane 26b .

In the implementation phase, modifications or additional non-described embodiments of the invention can be made to the cash closing system, the cash closing plant, the cash closing procedure and its use, object of the invention. If said modifications or said variants are within the scope of the following claims, all should be considered protected by this patent.
