DESCRIPTION OF THE PREFERRED EMBODIMENT

(10) Referring now to the drawings, and particularly to FIGS. 1-7, a preferred embodiment of the box erecting device and method of the present invention is shown by the reference numeral 1. Ah the humble box. From breakfast cereals, shoes, and mailing packages to auto parts, lawnmowers, and appliances, boxes carry a wide variety of goods within them. A box has a generally rectangular prismatic form with two opposite ends upon four walls in two parallel pairs. Each end has two minor flaps, generally beneath the thinner walls, and two major flaps, generally beneath the wider walls. A flap has less length then its corresponding wall has height and the same width as its corresponding wall. During assembly, a flat box is opened, the minor flaps are folded on one end, then the major flaps are folded upon the minor flaps, and the abutting major flaps are then secured to the minor flaps or otherwise.

(11) More particularly, a robotic carton erector machine manipulates a flat product on its way to becoming a box. The machine plucks, or picks a flat product from a supply stack with its grippers at the end of arm tooling of the robotic machine. Picking refers to the machine attaining control over the product in translation and in rotation without penetrating the product. Picking uses for example suction, air flow at lower pressure than ambient, magnetism, wide mechanical clamps, and the like. The machine then extends its grippers to open the product to a substantially rectangular, hollow, tubelike state. The machine next moves the product to press a bottom minor flap of the product upon a part of the invention. The machine continues its motion that moves the product to press the second bottom minor flap against a second part of the invention. Then the machine moves the product with its bottom minor flaps folded along a horizontal path of travel. Horizontal refers to parallel to the supporting surface beneath the machine and in the direction of the length of a spine of the machine as later described. The machine also holds the bottom flaps in their folded position and moves the product in a lateral direction nearly perpendicular to the horizontal path of travel to fold both bottom major flaps upward against the folded bottom flaps. And then the machine moves the product forward upon the invention in a horizontal path to seal the bottom major flaps in a closed state. Having described boxes and their path from flat to open for a load, the description turns to the invention that manipulates the box and its flaps along that path.

(12) FIG. 1 shows the invention 1 in a top view. The invention has a frame formed from a fore upright 10, here shown on end, and mechanically connected a spine 12. The spine is shown below the fore upright and extending perpendicular to the upright in the plane of this figure. The spine has its length greater than a length of the fore upright. Away from the fore upright, the spine has a middle member 13 extending upwardly from the spine and having the portion shown here parallel to the spine spaced beneath it. The middle member attains an elevation above the fore upright. The spine continues away from the middle member to an aft member 14. The aft member having a portion shown here coplanar with the portion of the middle member shown before it, that is, below in the plane of the figure, towards the fore upright 10. The aft member mechanically connects to an aft upright, not shown. The frame of the invention connects to an aft baseplate as at 21 below the aft upright and the spine 12. Opposite the aft baseplate, the invention has a fore baseplate as at 20 below the spine and between the fore upright 10 and the middle member 13. The two baseplates 20, 21 are located into the plane of this figure.

(13) Then below the spine, the frame of the invention 1 has a cross member 11 that mechanically connects to the spine. The cross member has its length greater than a width of the spine by at least a factor of four. The cross member extends outwardly from the spine and has a generally perpendicular orientation to the spine. The fore upright 10, spine 12, middle member 13, aft member 14, and cross member 11 form a generally T like shape as shown.

(14) Appearing outwardly from the frame, the invention 1 has a left rail 2, here shown to the left of the figure, and a counterpart right rail 3 to the right of the figure. The left rail and the right rail have a mutual spacing outwardly from the spine 12 as shown. The left rail 2 has a fore end as at 4 shown near the fore upright 10 and an opposite aft end as at 5 generally shown outwardly of the aft member 14. The right rail 3 has its fore end as at 6 shown near the fore upright 10 and its opposite aft end as at 7 generally shown outwardly of the aft member 14. As later shown, the fore ends 4, 6 of the rails 2, 3 have a mechanical connection to the fore upright 10 while the rails 2, 3 have a mechanical connection but to the cross member 11 spaced inward from the aft member 14 and the aft ends 5, 7 have a spacing outward from the aft member. The mechanical connections of the rails to the fore upright and the cross member allow for a user to adjust the elevation of each rail upon the fore upright, and the spacing of each rail from the spine upon the cross member. These adjustments allow the invention to receive and erect boxes of various sizes.

(15) Inverting the invention from the view in FIG. 1, FIG. 2 shows the invention 1 from the bottom, that is, with the baseplates 20, 21 in the foreground and the rails 2, 3 in the background of the figure. The baseplates have a generally square shape with at least two holes, preferably four holes, for anchor bolts, not shown. The spine 20 spans from the fore baseplate 20 to the aft baseplate 21. Above the aft baseplate, the invention has its cross member 11 extending left and right from the spine in this view, again forming a generally T shape. Into the plane of the figure, the rails 2, 3 extend from the fore upright, not shown, behind the fore baseplate 20 and over the cross member 11, that is, into the plane of the figure partially concealed behind the cross member. Here, as in FIG. 1, the rails flare outwardly from the spine upon the cross member. Unlike in FIG. 1, the rails have another portion of their cross section shown, here an edge. The rails have an angled shape, that is, L shaped cross section of two legs extending from a common center. Here, one leg is shown on edge while the other leg extends outward and flat from the first leg. The rails 2, 3 have their respective fore ends 4, 6 shown near each other and towards the bottom of the figure. The respective aft ends 5, 7 of the rails 2, 3 have their spaced apart positions above the cross member 11 towards the top of the figure.

(16) FIG. 3 then has the invention 1 shown from the side, its right side. The invention has its frame with the second rail 3 extending from the fore upright 10 along the spine 12, along the cross member 11 and outward and below the aft member 14. In this view the frame of the invention has additional components. The fore upright 10 joins perpendicular to the spine 12 and has a gusset 19 in the included angle between the fore upright and the spine. The gusset has a generally triangular shape and mechanical connections, not shown, to both the fore upright and the spine. Away from the fore upright, the frame has the middle member 13. The middle member has its elevation similar to that of the top of the fore upright. The middle member extends parallel to the spine below for a portion of the middle member's length. The middle member then bends downwardly towards the spine for the remainder of its length. The middle member keeps the same cross section through its length. The middle member then has a mechanical connection to the spine 12 using a plate 18 that covers a last portion of the middle member and the depth of the spine as shown. As before, the aft member 14 has a spacing away from the middle member while the aft member and the middle member maintain the same elevation. The aft member has a perpendicular connection to an aft upright 15, preferably by bolts. The aft member and the aft upright 15 also have another gusset 19 in the included angle between them. The aft upright 15 descends from the aft member and has its own perpendicular connection to the spine 12. The aft upright has that connection inward from the end of the spine as shown. And the aft upright and the spine also have another gusset 19 in the included angled between them and towards the fore upright as shown.

(17) Having shown and described the baseplates 20, 21 and spine 12 above, the spine connects to the baseplates as shown in this figure. The spine has a fore leg 16 that descends from it in the opposite direction as the fore upright 10. The fore leg has a spacing away from the fore upright, at least twice the thickness of the fore upright, as shown. The fore leg is generally located ahead of the center of the spine, that is, towards the fore upright. The fore leg 16 and the spine 12 have another gusset 19 between them in the included angle away from the fore upright. The fore leg 16 has its length greater than that of the fore upright. The fore leg's length has a magnitude compatible with a human operator or a robotic machine, and that fits along the flow path of box erection before the box reaches the invention and after the box departs the invention. Opposite the spine, the fore leg 16 fits into a socket 22 centered upon the baseplate 20. The socket has four second gussets 23, also triangular, that span outwardly from the socket toward the edges of the baseplate. The second gussets have an equiangular spacing about the socket. Preferably, the socket is of square cross section and a width suitable for receiving the foreleg in a tight connection.

(18) Away from the cross member 11, here shown on end, and from the aft upright 15, the spine has its aft leg 17 mutually parallel and spaced apart from the fore leg 16. The aft leg 17 descends from the spine 12 in the opposite direction as the aft upright 15. The aft leg has a spacing away from the aft upright, at least the thickness of the aft upright, as shown. The aft leg is generally located after the center of the spine, that is, towards the aft upright. In this view, the aft leg 17 and the spine 12 have a perpendicular connection without a gusset 19. In an alternate embodiment, the aft leg 17 and the spine 12 have another gusset 19 between them in the included angle towards the fore upright. The aft leg 17 has its length greater than that of the fore upright. The aft leg's length also has its magnitude compatible with a human operator or a robotic machine, and that fits along the flow path of box erection before the box reaches the invention and after the box departs the invention. The aft leg 17 has the same length as the fore leg 16. Opposite the spine, the aft leg 17 fits into a socket 22 centered upon the baseplate 21. This socket 22 also has four second gussets 23 of triangular shape that span outwardly from the socket toward the edges of the baseplate. The second gussets have an equiangular spacing about the socket as before and a square cross section and a width suitable for receiving the aft leg in a tight connection.

(19) With the frame described, the right, or second rail 3 extends from the left to the right of this figure from the fore upright 10 then down along the spine 12, out along the cross member 11, and outward and below the aft member 14. The right rail has an angle shaped cross section, later shown in FIGS. 5, 6, 7, with a first leg of the angle extending out of the plane of this figure toward the viewer and the second leg of the angle oriented downwardly aligned towards the fore leg 16 and the aft leg 17. The first leg of the angle and the second leg of the angle have a perpendicular orientation from a common vertex. Here, the vertex has its position towards the spine 12. Upon the first leg, the right rail has a layer 3a attached to it. The layer 3a provides a low friction surface for product, boxes, and cartons to slide upon. The layer 3a extends from the fore end 6 to the aft end 7 of the right rail 3. Low coefficient of friction includes from 0.05 to 0.51.

(20) Turning the invention once more, FIG. 4 shows a side view of the invention 1 with its left side in the foreground and the right side in the background. The invention has its frame with a left or first rail 2 that extends from outward and below the aft member 14, past the cross member 11, along the spine 12, and to the fore upright 10. From the left of this figure, as before, the aft member 14 has a spacing away from the middle member while the aft member and the middle member maintain the same elevation. The aft member has its perpendicular connection to the aft upright 15, preferably by bolts. The aft member and the aft upright 15 also have their gusset 19 in the included angle between them. The aft upright 15 descends from the aft member to its own perpendicular connection to the spine 12. The aft upright has that connection inward from the end of the spine as shown towards the left of the figure. The aft upright and the spine also have another gusset 19 in the included angled between them and towards the fore upright as shown. Away from the aft upright, the frame has the middle member 13 with its elevation similar to that of the top of the fore upright. The middle member extends parallel to the spine below for a portion of the middle member's length. The middle member then bends downwardly towards the spine and towards the aft upright for the remainder of its length. The middle member keeps the same cross section through its length. The middle member then connects mechanically to the spine 12 at the plate 18 that covers a last portion of the middle member and the depth of the spine as shown. Away from the plate 18 and the aft upright 15, the frame of the invention has the fore upright 10 joined perpendicular to the spine 12 with a gusset 19 in the included angle between the fore upright and the spine. The triangular gusset also mechanically connects to both the fore upright and the spine, connection not shown.

(21) As previously described, the spine 12 connects to the baseplates 20, 21 as shown in this figure. Away from the aft end 5 and the cross member 11, the spine has its aft leg 17 spaced away and before the aft upright 15. The aft leg 17 descends from the spine 12 in the opposite direction as the aft upright 15. The aft leg has a spacing away from the aft upright, at least the thickness of the aft upright, as shown. The aft leg has a general position before the center of the spine, that is, towards the aft upright. Here, the aft leg 17 and the spine 12 have a perpendicular connection that lacks a gusset. In an alternate embodiment, the aft leg 17 and the spine 12 include another gusset 19 between them towards the fore upright. The aft leg 17 has its length greater than the length of the fore upright above it. The aft leg's length also has its magnitude compatible with a human operator or a robotic machine, and that fits along the flow path of box erection before the box reaches the invention and after the box departs the invention. The aft leg 17 also has the same length as the fore leg 16 as shown so that the spine attains a level orientation to a horizontal plane defined by a surface beneath the baseplates 20, 21. Opposite the spine, the aft leg 17 fits into a socket 22 centered upon the baseplate 21 that has as before the four triangular second gussets 23 outwardly from the socket toward the edges of the baseplate. The second gussets have their equiangular spacing about the socket as before and a square cross section and a width suitable for receiving the aft leg in a tight connection.

(22) The spine has a fore leg 16 that descends from it in the opposite direction as the fore upright 10. The previously described aft leg 17 has its mutually parallel orientation and spacing apart from the fore leg 16. The fore leg has its spacing away from the fore upright, at least twice the thickness of the fore upright, as shown. The fore leg has its general position ahead of the center of the spine, that is, away from the plate 18 and towards the fore upright. The fore leg 16 and the spine 12 have the included gusset 19 between them. The fore leg 16 has its length greater than that of the fore upright. As before, the fore leg's length has a magnitude compatible with a human operator or a robotic machine, and that fits along the flow path of box erection before the box reaches the invention and after the box departs the invention. Then opposite the spine, the fore leg 16 fits into the socket 22 centered upon the baseplate 20. That socket has the four triangular second gussets 23, spanning outwardly from the socket toward the edges of the baseplate. The second gussets have their equiangular spacing about the socket. Preferably, the socket is of square cross section and a width suitable for receiving the foreleg in a tight connection.

(23) After describing this view of the frame, the left or first rail 2 extends from the left to the right of this figure from outward and below the aft member 14, past the cross member 11, upward along the spine 12, and to the fore upright 10. The first rail also has an angle shaped cross section, later shown in FIGS. 5, 6, 7. The angled shape has a first leg of it angle extending out of the plane of this figure toward the viewer and the second leg of it oriented downwardly aligned towards the fore leg 16 and the aft leg 17. The first leg of the angle and the second leg of the angle have a perpendicular orientation from a common vertex. Here, the vertex has its position towards the spine 12. Upon the first leg, the left rail has a layer 2a attached to it akin to the layer 3a. The layer 2a also provides a low friction surface for product, boxes, and cartons to slide upon. The layer 2a extends from the aft end 5 to the fore end 4 of the left or first rail 2. As before, low coefficient of friction includes from 0.05 to 0.51.

(24) FIG. 5 provides a front view of the invention 1 with the fore upright 10 and fore leg 16 in the foreground with the fore ends of the rails in the center of the foreground. This view shows the first rail 2 and the second rail 3 widening and descending from the top of the fore upright down past the cross member to their aft ends below the spine 12. Each of the fore ends, 4, 6 of the rails 2, 3 connects to the fore upright 10 using a mechanical connection, such as a clip 30 that bolts to the fore upright and the upright leg of each rail. The first rail 2 then extends downwardly and outwardly, that is, to the left in this figure to the cross member 11. The first rail also connects to the cross member mechanically, such as with another clip 30 to the upright leg of the rail, that is, the leg without the layer 2a. Outwardly and downward from the cross member, the first rail has its aft end 5 shown into the plane of the figure.

(25) In a near mirror image from the first rail 2 and the left portion of the invention shown, this view also shows the second rail 3 having its fore end 6 have a clip 30 type connection to the fore upright. Then the second rail 3 extends downwardly and outwardly, that is, to the right in this figure to the cross member 11 and shown opposite that of the first rail 2 described above. The second rail also connects to the cross member mechanically, such as with another clip 30 to the upright leg of the rail, that is, the leg without the layer 3a. Outwardly and downward from the cross member, the second rail has its aft end 7 shown into the plane of the figure. Though the two rails appear as mirror images in this figure, the rails may attain different curvilinear paths suitable for erecting certain boxes, cartons, and products during usage. As before, the fore upright 10 connects to the spine 12, the cross member 11 connects to the spine rearward of the fore upright, and the fore leg 16 depends from the spine 2 into the plane of this figure behind the fore upright. The fore leg 16 then fits into the socket 22 supported by its gussets 23 upon the baseplate 20.

(26) FIG. 6 then shows the invention 1 shown in a back view opposite that of FIG. 5. In this figure, the invention 1 has its aft upright 15 and aft leg 17 in the background into the plane of this figure and the aft ends of the rails spaced apart from the center of the foreground. This view shows the first rail 2 and the second rail 3 narrowing and rising from the two aft ends past the cross member 11 to their fore ends behind the aft upright. The rails 2, 3 have their respective fore ends 4, 6 approach the same plane as a layer 14a upon the aft member 14 so that the layers 2a, 3a, of the rails move products, boxes, and cartons into the plane of this figure. Similar to the above description, each of the rails 2, 3 along its length connects to the cross member 11 using a mechanical connection, such as a clip 30 that bolts to the cross member and the upright leg of each rail as shown. The second rail 3 then extends upwardly and inwardly, that is, to the right in this figure to the aft member, not shown, behind the aft upright 15. The second rail also connects to the fore upright mechanically into the plane of the figure, as previously described. Outwardly and downward from the cross member, the second rail has its aft end 7 shown out of the plane of the figure.

(27) In a near mirror image from the second rail 3 and the left portion of the invention shown, this view also shows the first rail 2 having along its length a clip 30 type connection to the cross member. Then the first rail 2 extends upwardly and inwardly, that is, to the left in this figure to the aft member, not shown, behind the fore upright 15 and shown opposite that of the second rail 3 previously described. The first rail also has its mechanical connection, such as a clip 30, to the cross member, upon the upright leg of the first rail, that is, the leg without the layer 2a. Inwardly and upward from the cross member, the first ail has its fore end 4 shown into the plane of the figure approaching the aft member. Though the two rails portray mirror images in this figure, the rails may make different curvilinear paths during usage for erecting certain boxes, cartons, and products. As before, the aft upright 16 connects to the spine 12, the cross member 11 connects to the spine forward of the aft upright, and the aft leg 17 depends from the spine 2 into the plane of this figure slightly behind the aft upright. The aft leg 17 connects to the baseplate 21 as it fits into the socket 22 supported by its gussets 23 thereon.

(28) Having described the invention 1 from six orthogonal views, turning the invention once more, FIG. 7 shows it in a perspective view. The rails 2, 3 extend from the left of the figure from the fore upright 10 to the right and down to the cross member. The rails 2, 3 continued past the cross member 11 so their fore ends 5, 7 span rearward of the cross member. The rails use clips 30, of a generally L like shape, to connect to the fore upright and the cross member. The fore upright and the cross member having lengthwise slots thereon as shown. The slots allow repositioning of a clip downward on the fore upright and outwardly on the cross member. Each rail may have different positions upon the fore upright and the cross member to erect a box of asymmetric pattern. Each rail has its layer, 2a, 3a, respectively, shown upward, that is, away from the baseplates 20. 21. The middle member 13 and the aft member 14 also have their layers 13a, 14a, respectively, shown upward so that the layers of the invention have similar orientation upward, that is, away from the baseplates 20, 21.
