Throughout this description, the term "sheet material" is used to designate corrugated cardboard sheet, corrugated plastic sheet, compact cardboard sheet, compact plastic sheet, and the like.

BACKGROUND OF THE INVENTION

Document FR2515141A1 shows a plate made of sheet material for the automated formation of a container by folding and embedding of said plate. Said plate comprises an essentially rectangular central panel delimited by four central panel edges. It also comprises a plurality of curved, specifically circular cutting units, made in the central panel to aid in the ventilation of the products, such as cheese, contained inside the container.

Likewise, the plate comprises two first flaps attached to the central panel by means of two respective alternate and mutually facing central panel edges. It also includes two second flaps facing and attached to the first two flaps by means of respective edges of the base panel. The plate has notches in these two second flaps to fit or engage one flap with the other to form a base panel. It also includes two third flaps attached to the central panel through the other two respective edges of the central panel alternate and mutually facing. It also comprises four corner reinforcement flaps attached to the two lateral ends, each first flap.

Also document FR2515141A1 the rectangular base container formed from said plate. The first two and two third flaps are folded perpendicular to the central rectangular panel forming the four side walls of the container. The base panel is made up of two second flaps fitted one with the other by means of notches. Therefore, the plate and container document FR2515141A1 is not suitable for its automated formation by folding and gluing.

In said document FR2515141A1 there is shown a device for the automated formation of a container by folding and embedding of a cardboard sheet that takes a die-cut (pre-cut) and grooved sheet of corrugated cardboard and forms it into a closed rectangular container. The plate is mounted on top of a male-like plate of the same dimensions as the central panel of the plate, which is moved by a cylinder. The plate is anchored to the plate by means of inverted 'L' shaped rotary grips that hold the central panel to the plate when the descent begins. Said twist grips are located through openings centered on the long edges of the center panel. In the downward movement, the plate is pressed against a forming mold that has a series of benders.

Documents ES8606124A1, ES2007712A6 and ES2691245A1 disclose a machine for the automated formation of tray-type packages by folding and gluing a cardboard sheet. The documents collect a machine comprising a plate loader suitable for placing plates, and a conveyor that transports said plates from a plate loader to a forming mold. It also includes glue equipment that is suitable for depositing lines of glue on the plate during transport. It also includes a male suitable for being introduced into a forming mold so that the male bends the parts of the plate against the forming mold, and a forming mold with an essentially rectangular cavity in which the male is insertable. It also includes glue injectors associated with glue equipment that deposit first lines of glue on the plate parallel to each other for gluing four reinforcing corners.

The machines of documents ES8606124A1, ES2007712A6 and ES2691245A1 show two benders for folding and gluing a flap attached to each of the two short side walls of the tray. Said attached flap is folded and glued against the short side wall. To this end, the benders include an actuator supported in said forming mold that moves a turning shaft in use and a turning shaft that moves a bending member in use between a position where the bending member does not interfere with the male and a position of final bend wherein the folding member presses the attached flap against the short side wall.

Thus, the benders fold the attached flaps about 180 ° from an intermediate position where they are essentially perpendicular to the center panel of the box, to a position where the attached flaps are again perpendicular to the center panel.

In document ES2007712A6 it is observed that the folding by means of both benders of the attached flaps is carried out at the same time, that is to say, synchronously. In other words, the angular position rotated by each rotation shaft is symmetrical at all times.

None of the documents found discloses a plate suitable for its automated formation by folding and gluing in a tray-type container forming machine by adapting the forming mold, the male and the position of deposition of the glue lines, being said iron once a rectangular base container has been formed, closed on the top by a central panel, on the bottom by a base panel and at least on two sides. In said container a plurality of unitary products such as glasses, eggs, flowerpots, objects of circular or oval longitudinal section, etc. are structurally supported individually. It would be desirable if the plate had an easy and fast automatic formation and the production costs of the plate and the container were reduced.

None of the documents found disclose a method or machine for the automated formation by folding and gluing of said plate and container, which are detailed in the previous paragraph and in the explanation of the invention.

Fig. 9 shows the product units (23).

Likewise, in the plate (10) of Fig. 1, the sum of the extensions (17) of the two respective second flaps (5) perpendicular to the first two edges of the central panel (1a) is greater than a second edge of the central panel (1b) parallel to said extensions (17).

Also, in Fig. 1, when the two second flaps (5) are folded, they define an overlapping area (21), on which a second flap (5) can be glued coplanarly with the other second flap (5) by means of the minus a first glue line (7) and thus obtain a base panel (22) essentially parallel to the central panel (1).

Starting from the plate (10) there is a container (20) closed at the top by the central panel (1), closed at the bottom by the base panel (22) where the product units (23) are capable of being vertically supported , and closed on two sides by the first flaps (2).

Thus, a plate (10) suitable for its automated formation by folding and gluing is obtained in a tray-type container forming machine by adapting the forming mold, the male and the position of deposition of the glue lines, said plate being (10) once a container (20) with a rectangular base has been formed, closed at the top by a central panel (1), at the bottom by a base panel (22) and at least by two sides (2).

The base panel (22) of Figs. 8, 17 and 18 comprise two second flaps (5) folded around the edges of the base panel (19) and bonded coplanarly to one another in an overlapping area (21) so that the two second flaps ( 5) lie in a plane essentially parallel to the central panel (1).

In Figs. 8, 17 and 18 the base panel (22) further comprises an overlapping area (21) in which a second flap (5) is glued coplanar to the other, and wherein the overlapping area (21) comprises two first glue lines (7) that stick a second flap (5) with the other.

In Fig. 8, the base panel (22) includes two first glue lines (7) that glue a second flap (5) to the other, said two first glue lines (7) being parallel to the central panel ( one).

In the container (20) of Fig. 9, the plurality of cut-off units and / or weakened segment (13, 14, 15) made in the central panel (1) are dimensioned for the partial introduction of product units (23 ) through the central panel (1) so that these product units (23) are fitted laterally individually in the container (20) in said respective units of cuts and / or weakened segments (13, 14, 15).

Thus, in Figs. 8 and 9 the container (20) is closed at the top by the central panel (1), at the bottom by the base panel (22) and on two sides by the first flaps (2).

In Figs. 7 to 9, the container (20) further comprises two second side walls essentially perpendicular to the central panel (1) formed by folding two third flaps (3) attached to the central panel (1) by the other two respective second panel edges central (1b) alternate and mutually opposite.

Also in Figs. 7 to 9 it is observed that the container (20) also comprises four reinforcing flaps (6) attached to the lateral ends of the first two flaps (2). Likewise, in Figs. 6 and 8 it is observed that the container (20) includes sixteen second glue lines (8) parallel to each other, perpendicular to the first two glue lines (7) and to the central panel (1) and that they join by gluing each one of the four reinforcement flaps (6) coplanarly with a first side wall. Each reinforcement corner (6) has four second glue lines (8). Thus, the container (20) is reinforced at its corners with the four reinforcing flaps (6) and closed by the four side walls by means of the first two and two second flaps (2, 3).

In the sequence of formation of the container (20) from the plate (10) of Figs. 6 to 9 show that each of the cutout units and / or weakened segment (13, 14, 15) made in the central panel (1) have at least one cutout and / or weakened segment with a curved shape for partial introduction of a product unit (23) of substantially circular or oval cross section. More specifically, in Figs. 6 to 9 each of the weakened cutout and / or segment units (13, 14, 15) comprises two curved cutouts (14) with their concave faces facing each other, and a dividing cutout (13) that joins a curved cutout (14) with the other. The two curved cutouts (14) and the dividing cutout (13) define a first fin (11) and a second fin (12). The first and second flaps (11, 12) are foldable for the partial introduction of a product unit (23) of substantially circular or oval cross section.

In a second embodiment of said container (20), each of the cut-out units and / or weakened segment (9, 18, 13, 14, 15) comprises a circular cut (9) like that of the plates in Figs. 4 and 5, for the partial introduction of a product unit (23) of circular or oval cross section.

In a third embodiment of said container (20), each of the weakened cutout units and / or segments (9, 18, 13, 14, 15) comprises a hollow oval cutout (18) like that of the plate (10) of Fig. 3, for the partial introduction of a product unit (23) of oval cross section.

In a fourth embodiment of container (20), the two second flaps (5) have a second flap length (16) shorter than the edge of the base panel (19), as observed in the development of plate (10 ) of Fig. 5. This prevents the ends of the two second flaps (5) from interfering with the side walls formed by the third flaps (3) when the second flaps (5) are folded parallel to the central panel (1 ). Fig. 16 illustrates this point.

According to a third aspect, the invention provides a method for the automated formation of a container (20) by folding and gluing a plate (10).

Said method comprises the step of laying a flat plate (10) like those shown in Figs. 1 to 6 in a plate loader (120) as illustrated in Fig. 22. Said plate (10) comprises an essentially rectangular central panel (1) that closes the container (20) at the top once formed, two first flaps ( 2) attached on alternate sides (1a) of the central panel (1), and two second flaps (5) mutually facing and attached to the first two flaps (2) by means of respective edges of the base panel (19).

It also comprises the step of transporting said plates (10) from the plate loader (120) to a forming mold (100). Figures 4 and 6 indicate the transport direction (T) of the plate (10) parallel to the edges of the base panel (19), while in Figure 5 the transport direction (T) is perpendicular to the edges of the base panel (19).

In the illustrated example of Figs. 6 to 8, the method further comprises the step of depositing two first lines of glue (7) on one of the two second flaps (5) in an overlapping area (21) for subsequent gluing of said second flap (5) with the other second flap (5) shown in Figs. 17 and 18.

Figs. 6, 7, 13, 14, and 21 show that the method includes bending two first flaps (2) by means of a forming mold (100) and a male (110) capable of being introduced linearly into the forming mold (100), in such a way that the male (110) presses against the central panel (1) and bends the plate (10) against the forming mold (100), and the first flaps (2) and the second flaps (5) are perpendicular to the central panel (1 ) in an intermediate folding position. In Figs. 6 and 13 the plate (10) is flat and has not been inserted into the forming mold, while in Figs. 7, 14 and 15 the plate (10) is in said intermediate bending position.

Likewise, the method includes folding the two second flaps (5) from the intermediate folding position of Figs. 7, 14 and 15 where the two second flaps (5) are essentially perpendicular to the central panel (1) and essentially parallel to the first flaps (2), to a final folding position of Figs. 8, 17 and 18 where the two second flaps (5) are essentially parallel to the central panel (1) and essentially perpendicular to the first flaps (2). In Figs. 15-17 it is shown that the folding of a second flap (5) in the final folding position is carried out before the folding of the other second flap (5) in the final folding position.

Likewise, in Figs. 14 to 18 it is noted that the method includes the step of moving the core (110) out of the cavity (45) of the forming mold (100) before the step of folding the two second flaps (5) from their respective intermediate folding positions. to their respective final folding positions and after the step of folding the first two flaps (2).

In Figs. 8, 17 and 18 illustrate the step of gluing said second flap (5) to the other second flap (5) in the final folding position by means of two first glue lines (7) located in the overlapping area (21) to forming a base panel (22).

Thus, a container (20) is obtained closed superiorly by the central panel (1), inferiorly by the base panel (22) and laterally by the first flaps (2) as shown in Figs. 8, 17 and 18.

Figs. 6 and 13 show that in the step of placing the plate (10), said plate also comprises two third flaps (3) attached to the central panel (1) by means of the other two respective second edges of the central panel (1b) alternate and mutually facing . Said plate (1) further comprises four corner reinforcement flaps (6), attached to the lateral ends of the first flaps (2).

Figs. 6 and 13 show the step of depositing sixteen second glue lines (8) parallel to each other on the plate (10) for gluing the four reinforcing flaps (6) coplanarly with a first or second flap (2, 3). Four glue lines (8) are used for gluing each reinforcement flap (6).

Also, Figs. 7, 8, 17 and 21 show that the method includes the step of bending by means of a forming mold (100) and a male (110), so that the two third flaps (3) and the four reinforcing flaps (6) are perpendicular to the central panel (1), and the four reinforcement flaps (6) are glued coplanarly with a first or second flap (2, 3).

Figs. 17 and 18 show that, after the step of folding the two second flaps (5) from the intermediate folding position to the final folding position, the method comprises the step of keeping both second flaps (5) in the final folding position a time to help the gluing of a second flap (5) with the other by means of the first two glue lines (7) shown in Fig. 8.

Fig. 15 shows that the method further comprises the step of supporting the plate (10) in two lower stop assemblies (90) the central panel (1) when it is introduced into the cavity (45) of the forming mold (100). Fig. 15 shows that the method comprises the step of keeping the plate (10) in the position introduced in the forming mold (100) by means of two non-return stop sets (80) so that it is not dragged by the outlet of the male ( 110).

According to a fourth aspect, the present invention provides a machine (200) for the automated formation of a container (20) by folding and gluing a plate (10).

In Figs. 21 and 22 it is shown that said machine (200) comprises a plate loader (120) suitable for placing plates (10), and a conveyor (130) that transports said plates (10) from a plate loader (120) to a forming mold (100).

In Fig. 22 it can be seen that the machine (200) also comprises a glue equipment equipped with glue injectors (140) that deposits in use two first lines of glue (7) on the plate (10) during transport. In Figs. 4, 5, 6 and 13 the plate is shown with two first lines of glue (7).

Likewise, in Figs. 21 and 22 it is shown that the machine (200) comprises a male (110) capable of being introduced into a forming mold (100) so that the Male (100) bends the parts of the plate (10) against the forming mold (100), and a forming mold (100) with an essentially rectangular cavity (45) in which the male (110) is insertable. Said cavity (45) is seen in Fig. 14.

In said machine (200), the forming mold (100) shown in Figs. 10, 13 to 18 and 21 comprise six first benders (50) three of them mutually facing the other three and arranged for bending two first flaps (2) of the plate (10) mutually facing and attached to the central panel of the plate (10) on two alternate sides.

In Figs. 10, and 14 to 18, the forming mold (100) further comprises two mutually facing second benders (70), to bend two second flaps (5) attached to the first flaps (2) by means of respective base panel edges (19) alternate and mutually opposed. Each second folder (70) bends a second flap (5), from the intermediate position of Figs. 7 and 15 where it is perpendicular to the central panel (1) and parallel to the first flap (2), up to a final position of Figs. 8, 9, 17 and 18 where each second flap (5) is parallel to the central panel (1) and perpendicular to the first flap (2).

In Figs. 10, and 13 to 18 it is shown that each second bender (70) comprises an actuator (71) supported on said former mold (100) which moves a rotary shaft (72) in use. Also each second bender (70) comprises a turning shaft (72) parallel to the turning shaft of the other second bender (70) that moves in use a bending member (73) between said intermediate position and said final position of the second benders ( 70). Likewise, each second bender (70) includes said bender member (73) connected to the turning shaft (72).

In Figs. 15 to 18 the folding sequence of the two second flaps (5) is shown. In said figures a second bender (70) of the forming mold (100) bends a second flap (5) in the final position before the other bending device (70) bends the other second flap (5) in the final position. This order of folding is necessary for the formation of the base panel (22) (Figs. 17 and 18) by gluing a second flap (5) with the other in the overlapping area (21).

In Figs. 6 and 13, the glue equipment that is an integral part of the machine (200) deposits at least one first line of glue (7) on one of the two second flaps (5) in the overlapping area (21), for said subsequent gluing of said second flaps (5) and obtaining the base panel (22).

The forming mold (100) that is an integral part of the machine (200), as shown in Figs. 10, 13, 14 and 21 also comprise two third benders (40) facing each other and perpendicular to the first benders (50). The two third benders (40) are arranged for the bending of two third flaps (3) of the plate (10) mutually facing and attached to the central panel (1) of the plate (10) on two other alternate sides. Similarly, in machine 200, forming mold 100 includes four corner benders 60 located at the corners of the cavity 45 between a first bender 50 and a third bender 40, arranged to the folding of the corner reinforcements (6) attached to the lateral ends of the first flaps or second flaps (2, 3). Also, in Figs. 6, 13 and 22 the glue equipment is configured to deposit second glue lines (8) by means of glue injectors (140) for gluing the corner reinforcements (6).

Figs. 15 and 19 show that the machine (200) further comprises a first activating and deactivating element (V1) of the actuator (71) that moves the rotary shaft (72) belonging to a second bender (70) in use. Likewise, in Fig. 19 the machine (200) comprises a second activation and deactivation element (V2) of the other actuator (71) that moves the rotation shaft (72) belonging to the other third bender (70) in use.

In Figs. 15 and 19, the actuators (71) are fluid dynamic cylinders provided with a body and a rod. Each rod has fixed a rack (74) that meshes with a pinion (75) that moves said rotation shaft (72). Said two activation and deactivation elements (V1, V2) are solenoid valves governed by respective coils (Y1, Y2). Depending on whether the coils (Y1, Y2) have voltage or not, they change the position of their respective solenoid valve (V1, V2) to one side or the other, and make the rod of the fluid dynamic cylinder (71) move in use towards out or in. The function of the first and second activation and deactivation elements (V1, V2) is the activation of an actuator (71) of a second bender (70) before the other actuator (71) of the other second bender (70).

This achieves the folding of a second flap (5) in the final folding position before the folding of the other second flap (5) in the final folding position, as shown in Figs. 15 to 17. Thus, an activation and deactivation of the benders (70) is achieved independently, since there is a solenoid valve for each fluid dynamic cylinder.

Fig. 20 shows an alternative option to achieve the folding of a second flap (5) in the final folding position before the folding of the other second flap (5) in the final fold position. In Fig. 20, the machine (200) comprises a first activation and deactivation element (V1) of the actuators (71) common to the two second benders (70). Also in Fig. 20 the machine (200) includes a delay element (RC), specifically a flow regulator, connected to one of the actuators (71) in such a way that the movement of this actuator (71) is slower than that of the other actuator (71), to achieve the folding of a second flap (5) in the final folding position before the folding of the other second flap (5) in the final folding position (Fig. 17). In Fig. 20, the actuators (71) are fluid-dynamic cylinders equipped with a body and a rod, and the deactivation activation element (V1) is embodied in a solenoid valve (V1). Obviously, both cylinders can have two retarding elements (RC), such as two speed regulators, to achieve the same effect. Such option is within the scope of this document.

In Figs. 15, 19, and 20 the fluid dynamic cylinders are fed by compressed air through an air supply element (S). Said supply can be provided by an air compressor that is or is not an integral part of the machine (200).

According to another alternative option, a second bender (70) of Figs. 16-18 is mechanically configured to reach the final bending position before the other second bender (70).

Fig. 17 shows that one of the second benders (70) maintains both second flaps (5) in the final folding position for a time to help the bonding of a second flap (5) with the other by means of the first two glue lines. (7) shown in the container (20) of Fig. 8.

In the machine embodiment of Figs. 10 to 22, the forming mold (100) of the machine (200) further comprises two non-return stop assemblies (80) facing each other.

In Figs. 10, 11 and 15 it is shown in detail that each anti-return claw assembly (80) comprises a non-return claw support (81) fixed in use to the mold (100) and located above the container (20) once formed . Each anti-return pawl assembly (80) also includes a non-return pawl (82) hingedly supported on the bracket (81) by a hinge (83). In Fig. 15 it is shown in detail that the two anti-return stop assemblies (80) serve so that the plate (10) with some bending operations is kept in the position introduced in the forming mold (100) and is not dragged by the outlet of the core (110).

In Figs. 10, 12 and 15 the forming mold (100) of the machine (200) is also shown in detail, it also comprises two mutually facing stop assemblies (90). Each pawl assembly (90) comprises a pawl holder (91) attached in use to the former (100), and a pawl actuator (92) supported on the pawl holder (91). In Figs. 12 and 15 the claw actuator (92) is a fluid dynamic cylinder and moves said claw (93) between a retracted position where it is not inserted in the cavity (45) of the forming mold (100) and a stop position where it serves bottom stop to the central panel (1) when the plate (10) is introduced into the cavity (45) of the forming mold (100).
