During shipping, a support assembly as part of a packaging system can protect a shipped object, such as a large-scale printer, from accidental damage. As part of the support assembly, a cuboid alignment of support beams can be mounted on top of a shipping pallet.
The following detailed description will best be understood with reference to the drawings, wherein:
During the packaging of large-scale objects, such as a printer, the cuboid alignment of the support structure may involve alignment of large components at elevated positions. The use of an alignment means can hereby be employed for mounting or aligning the support structure. In some examples, a load transmitter jig or fixation member may be used to improve the alignment of the components in several dimensions.
The form of the load transmitter jig may support a positioning and alignment of the components of packaging arches as part of the support structure. An improved alignment of components of the support structure may reduce assembly times or associated costs, while it may also be advantageous for process quality or a security aspect during the assembly of the shipping structure, such as a more ergonomical mounting procedure.
In addition, a shipped object, such as a printer, may be protected from accidental damage due to a precise alignment of the components. The alignment may improve an ability of the support structure to accommodate compression or shear forces, and may hence preserve a structural integrity of the shipped object during shipment.
In addition, the fixation member may provide alignment or fixation options for protective parts of the support structure, such as spacers, which may reduce a translation of the shipped object during shipment, such as a transverse movement of a printer. Moreover, the fixation member may provide fixation options for mounting additional parts of the shipped object to the support structure, such as exchangeable parts or features of a printer.
The support structure may be employed for the packaging of all types of printer devices and printer equipment, including 2D and 3D (additive) printers.
An example of a fixation member 10 is shown in
The fixation member 10 can support the alignment of features or components of a packaging assembly during mounting and transport. A degree of asymmetry in the arrangement of the fixation member 10 can allow for several mounting strategies with the same fixation member 10 and hence increase the flexibility of the assembly.
The fixation member 10 may be formed as one piece, which can reduce fabrication complexity and can increase structural integrity. Hence, the fixation member 10 may be a one-piece fixation member.
The support structure 12 of the fixation member 10 supports the at least two L-shaped projections 16a,16b and may support a beam mounted on a bottom surface 22 of the support structure 12, wherein the bottom surface 22 is on an opposite side of the support structure 12 with respect to the top surface 14.
As shown in
In
The L-shaped projections 16a,16b extending from the support structure 12 may be angular pieces or elbow fittings. They may comprise mathematical cylinders, wherein a three-dimensional structure may be formed by a parallel displacement of a cross-section with an L-shape from a first surface along a straight vector towards an identically shaped second surface, the first and second surfaces being L-shaped.
The cross-section of the first L-shaped projection 16a and the cross-section of the second L-shaped projection 16b may be mathematically similar, congruent, or identical L-shapes. In some examples, the cross-sections of the L-shaped projections 16a,16b may also be distorted with respect to each other due to a non-isometric transformation.
The straight vector of the first L-shaped projection 16a may be different from or equal to the straight vector of the second L-shaped projection 16b with respect to orientation and length. As an example, the straight vector may be along the normal of the top surface 14 of the support structure 12, or, in other words, the L-shaped projections 16a,16b may extend along the normal of the top surface 14 from the top surface 14 of the support structure 12.
In an example depicted in
The L-shape (of the cross-section) may be constructed from two overlapping rectangles, wherein a longer side of each rectangle is oriented in a different spatial direction and wherein the two rectangles may share one common corner. However, the corner may also be rounded, cut or comprise an extruded feature without deviating from the L-shape of the L-shaped projection 16a,16b. The common corner may then be a virtual corner formed by the projections of the longest outer sides of the two rectangles.
In other words, the L-shape may be constructed from a polygon with six corners that is characterized by an inner angle that is greater than 180°. For example, one inner angle of the L-shape may be 270° and five other inner angles may be 90° as shown in
The first and second L-shaped projections 16a,16b further comprise the base surface 18a,18b and the side surface 20a,20b that may be outer surfaces of the L-shaped projections 16a,16b. Accordingly, an intersection of tangential planes corresponding to the base surface 18a,18b and the side surface 20a,20b may lie along the common corner. In other words, the base surface 18a,18b and the side surface 20a,20b may be outer surfaces of the L-shape that meet at the corner of the L-shape, which is opposite the corner associated with an inner angle greater than 180°.
The L-shape of the L-shaped projections 16a,16b allows for a plurality of mounting strategies for mounting an external feature or a component of a packaging assembly to the fixation member 10 with the same fixation member 10.
For example, the base surface 18a,18b and the side surface 20a,20b of the L-shaped projections 16a,16b may each provide a mounting support to connect the fixation member 10 to an external feature. The fixation member 10 may thereby provide a fixation along several different spatial directions. In addition, the fixation member 10 may allow for self-alignment of the external feature with the fixation member 10 by connecting a surface of the external feature to the top surface 14 of the support structure 12 and a different surface of the external feature to the base surface 18a,18b or the side surface 20a,20b of the first or the second L-shaped projection 16a,16b.
The external feature may be a structural component whose alignment is supported by the fixation member 10. For example, the external feature may be a component or part of a construction such as a plate or a beam. As an example, a packaging structure may comprise an alignment of beams on top of a shipping pallet. The fixation member 10 may be used to fix the beams to the pallet, align several beams with respect to each other, or provide mounting support for additional beams to accommodate shear forces. In the example of the shipping pallet, the fixation member 10 may be used with arbitrary combinations of materials for the pallet and the beams. For example, the beams or the pallet may be made from an organic material such as wood, a composite material such as plywood, a plastic, a metal, or the like.
The (self-)alignment of the external features can be supported by the arrangement of the L-shaped projections 16a,16b on top of the support structure 12. For example, a cavity or mounting space 23 may be formed between a surface of an L-shaped projection 16a,16b and the top surface 14 of the support structure 12. The cavity 23 may constrain the movement of the external feature with respect to the fixation member 10, and may support the self-alignment of the external feature to the fixation member 10.
In an example shown in
In addition, the base surface 18a of the first L-shaped projection 16a and the base surface 18b of the second L-shaped projection 16b may also define a common flat plane. Accordingly, the cavity 23 is formed between both of the base surfaces 18a,18b of the L-shaped projection 16a, 16b and the top surface 14 of the support structure 12.
In some examples, the first L-shaped projection 16a and the second L-shaped projection 16b may overlap or be connected by extruded features, such that the base surfaces 18a,18b are connected, which may increase a structural integrity of the fixation member 10. In other examples, the first L-shaped projection 16a and the second L-shaped projection 16b are connected via the top surface 14 and the fixation member 10 comprises a gap between the first L-shaped projection 16a and the second L-shaped projection 16b. The gap may separate the first L-shaped projection 16a and the second L-shaped projection 16b. The gap may decrease a weight of the fixation member 10, may provide arrangement or alignment options for external features, or may give a visual indication of directionality for alignment.
In addition, the side surface 20a of the first L-shaped projection 16a or the side surface 20b of the second L-shaped projection 16b may also not be aligned with an edge of the support structure 12. A side cavity 25 or side mounting space may be formed between the side surface 20a,20b of the first or the second L-shaped projection 16a,16b and the top surface 14 of the support structure 12.
Referring now to
In some examples, the side surface 20a of the first L-shaped projection 16a or the side surface 20b of the second L-shaped 16b projection may be aligned with an edge of the support structure 12, as shown in
An example of a fixation member 10 may further comprise a mounting protrusion 24a,24b; 26a,26b; 28a,28b, such as a base-side mounting protrusion 24a,24b, a bottom-side mounting protrusion 26a,26b (not shown in
The fixation member 10 may also comprise several mounting protrusions on equal or different surfaces of the fixation member 10. Thus, the alignment of an external feature may be supported by at least one mounting protrusion or the alignment of the external feature may be supported by one of the mounting protrusions in different spatial directions. Supporting the alignment of the external feature with several mounting protrusions may result in a stricter alignment, while supporting the alignment of the external feature with one mounting protrusion may allow greater alignment tolerances.
The mounting protrusion may be a mathematical cylinder protruding from a surface of the fixation member 10. The mounting protrusion may engage a corresponding hole of an external feature, which can support the self-alignment of the external feature. The cross-section of the mounting protrusion may be circular, rectangular, triangular, cross-shaped, or star-shaped, a combination of several shapes, or the like and may comprise a hole. For example, the mounting protrusion may be a hollow cylinder as shown in
A circular cross-section of the mounting protrusion may allow a flexible alignment of an external feature within a plane along the respective surface that the mounting protrusion extends from, while a different shape may result in a stricter alignment of the external feature. A receding cross-section may increase an initial alignment tolerance of the external feature to the fixation member 10, while a shape corresponding to a mathematical cylinder may provide a more constraining fixation of the external feature with respect to the fixation member 10.
As shown in the example of
Particularly, the fixation member 10 may comprise a first base-side mounting protrusion 24a extending from the base surface 18a of the first L-shaped projection 16a and a second base side mounting protrusion 24b extending from the base surface 18b of the second L-shaped projection 16b. Hence, an external feature may be aligned to both of the first and second L-shaped projections 16a, 16b at the same time or two external features may separately be aligned to the first and second L-shaped projections 16a, 16b, respectively.
Further, as shown in the side views of the fixation member 10 according to
Referring to
As shown in
The fixation hole 30 can provide a guide for a connection piece, such as a screw or the like, to fix an external feature to the fixation member 10. Such a fixation may increase a rigidity of the assembly. The fixation hole 30 may be adapted to the connection piece, such as having a circular cross-section.
The surfaces may be on opposite side of the fixation member 10. The surfaces may comprise the top surface, the base surface, or the side surface.
The fixation member 10 may be made from a plastic, a metal, an organic material, a composite material, or the like. For example, the fixation member 10 may be made from a high-impact plastic, an iron based metal, or wood. The material can be selected according to structural characteristics such as flexibility, rigidity, compatibility with further components of an assembly, weight, cost, or the like.
A plastic fixation member 10 may be injection molded, 3-D-printed, or extruded and may hence be produced with arbitrary detail and have a low production cost. For example, when used in a packaging support structure, a plastic fixation member 10 may be an advantageous tradeoff or compromise between structural integrity, modelling difficulty, material cost and/or weight.
As illustrated in
The voids 32 and the webs 34 may improve the characteristics of the fixation member 10 during fabrication. For example, the webs may have a similar thickness, such as to reduce a warping effect on the fixation member 10 during injection molding. Furthermore, the voids 32 may reduce the weight or the material cost of the fixation member 10. In
As depicted in the example of
The fixation member 10 may be used as a load transmitter jig 10.
As shown in
The inner surfaces 36a,36b of the first L-shaped projection 16a and the second L-shaped projection 16b are opposite of the base surfaces 18a,18b and the side (flank) surfaces 20a,20b of the first L-shaped projection 16a and the second L-shaped projection 16b. In other words, the inner surfaces 36a,36b or their projections meet at the corner of the L-shape, which is associated with an inner angle greater than 180°.
As explained with reference to the fixation member 10 of
The alignment of the external feature to the load transmitter jig 10 may be supported by the cavity mounting protrusions 24a,24b that may engage a corresponding hole of the external feature, such as a hole of a beam.
The further cavity 35 of the load transmitter jig 10 may be used to facilitate a connection between the fixation member 10 and an external feature connected to the base surfaces 18a, 18b or a flank 20a,20b of the first L-shaped projection 16a or the second L-shaped projection 16b. For example, the further cavity 35 may provide a space for aligning or performing a screw connection between the fixation member 10 and the external feature.
However, the further cavity 35 of the load transmitter jig 10 may also provide an alignment possibility for an external feature, such as a beam arranged at least partially within the further cavity 35. For example, a beam whose width corresponds to the distance between inner surfaces 36a,36b of the first L-shaped projection 16a and second L-shaped projection 16b may be wedged into the further cavity 35. Moreover, the further cavity 35 may also provide a mounting support for other features of an assembly, such as a spacer, a diagonal beam, or an equipment holder.
In addition, the load transmitter jig 10 may comprise further features of the fixation member 10 as described above with reference to
For example, the load transmitter jig 10 may further comprise a bottom mounting protrusion (such as the bottom-side mounting protrusions 26a,26b shown in
In some examples, the load transmitter jig 10 may comprise a flank mounting protrusion (such as the flank mounting protrusions 28a,28b shown in
In some examples, the load transmitter jig 10 may be a one-piece load transmitter jig. The one-piece load transmitter jig may be fabricated from one piece. A one-piece load transmitter jig may be easier to produce or may have improved structural integrity with respect to a composite piece.
In some examples, the load transmitter jig 10 or the fixation member 10 are used as load transmission or alignment means for a printer packing support structure. The above described structural features may then be adapted in a method for aligning external features, such as beams, of an assembly, in particular components of a packaging structure or a printer packaging structure.
As shown in
An example of an assembly with a load transmitter jig 10 connected to several components is illustrated in
The first component 38 and second component 40 are external features that are external to the load transmitter jig 10 and are components of the assembly, for example a shipping pallet or a structural beam to be assembled on top of the shipping pallet using the load transmitter jig 10. However, any external feature or component may be used, such as external plates to be assembled in a cuboid structure, or the like.
As described above with reference to the fixation member 10 or the load transmitter jig 10, protruding features or holes may be used during the mounting of the components to the load transmitter jig 10. For example, the mounting of the load transmitter jig 10 to the first component 38 may comprise engaging a hole of the first component 38 with a cavity protrusion 24a,24b extending from a base surface 18a,18b of the first L-shaped projection 16a or the second L-shaped projection 16b.
As a further example, the mounting of the load transmitter jig 10 to the first component 38 may comprise aligning the first component 38 in a beam fixation cavity 23 formed by the top surface 14 of the principal plate 12 and a base surface 18a, 18b of the first L-shaped projection 16a or the second L-shaped projection 16b, or a base surface 18a, 18b of both the first L-shaped projection 16a and the second L-shaped projection 16b.
Further, mounting the second component 40 to the bottom surface 22 of the principal plate 12 may comprise engaging a hole of the second component 40 with a bottom protrusion 26a,26b extending from the bottom surface 22 of the principal plate 12.
Furthermore, the method may comprise mounting a third component 42 to a flank protrusion 28a,28b of the load transmitter jig 10, wherein the flank protrusion 28a,28b engages a hole of the third component 42, and wherein the flank protrusion 28a,28b extends from the first L-shaped projection 16a or the second L-shaped projection 16b.
In some examples, several load transmitter jigs 10 may be used in an assembly. For example, several identical load transmitter jigs 10 may be used to construct and align a packaging assembly, wherein several assembly strategies may be used with the load transmitter jigs 10.
As an example, the method may comprise mounting a second load transmitter jig 44 to a packaging support structure, such as the example of the second component 40 shown in
As described with reference to the fixation member 10 and the load transmitter jig 10 above, a bottom protrusion of the second load transmitter jig 44 may engage a hole of the packaging support structure and/or a cavity mounting protrusion of the second load transmitter jig 44 may engage a further hole of the first component 38, wherein the bottom protrusion and the cavity mounting protrusion may be arranged at different sides of the second load transmitter jig 44.
It is therefore possible to connect one component to several load transmitter jigs 10,44 to construct the assembly. In addition, it is possible to connect several components to the same orientation or surface of the load transmitter jig 10.
For example, the method may comprise mounting a fourth component 46 to the load transmitter jig 10, wherein a first surface of the fourth component 46 contacts a base surface 18a,18b of the first L-shaped projection 16a or the second L-shaped projection 16b, and a second surface of the fourth component 46 contacts the top surface 14 of the principal plate 12, wherein the first surface and the second surface may be different.
In addition, a third surface of the fourth component 46, which may be different from the first surface and the second surface, may contact a third surface of the first component 38, wherein the first component 38 and the fourth component 46 are connected to the same load transmitter jig 10.
Additionally, a further cavity mounting protrusion 24a,24b of the load transmitter jig 10 may engage a hole of the fourth component 46. The cavity protrusion 24a,24b and the further cavity protrusion 24a,24b may each extend from different base surfaces 18a,18b each corresponding to the first L-shaped projection 16a and the second L-shaped projection 16b, respectively.
Moreover, the method may comprise mounting a fifth component to a further cavity 35 or further mounting space of the first load transmitter jig 10, wherein the further cavity 35 is formed by two inner surfaces 36a,36b of each of the first L-shaped projection 16a and the second L-shaped projection 16b, and the top surface 14 of the principal plate 12.
Some of the above mentioned mounting options are illustrated in
In addition, the method may comprise fixing an external feature to the load transmitter jig 10 with a connection piece, such as a screw or the like. However, a rigid connection may also be established by a positive-locking or interlocking piece of the load transmitter jig 10 or by a firm bond, such as a glue connection.
