JP5605609B2 - Retention system for horizontally or vertically stacking framed photovoltaic or solar electronic planar modules - Google Patents

Description

      The present invention relates to a material saving and reusable bundle holding system for loading and transporting framed photovoltaic or solar electronic planar modules.

    The system consists of individual molded parts. These molded articles form pillars or crosspieces that can be transported stably and safely by mechanical engagement and by means of a constrained connection by the frame of the module.

      The excellent feature of the system according to the invention is that it is suitable for stacking photovoltaic or solar thermoelectric planar modules with frames in the vertical and horizontal directions as well.

      Over the past few years, the use of reusable energy has become increasingly important in terms of energy policy and economics, due to global climate change, scarce fossil fuel resources and increasing energy costs It is becoming.

      For example, a very efficient industry has been established in the field of solar energy utilization. Photovoltaic modules or solar thermoelectric planar collectors are now generally produced as mass-produced products that are automated through the use of manufacturing robots.

      In this respect as well, the rationalization demands that have been observed for many years in the automobile production industry, for example, are basically applicable today.

  This also applies to the final process, ie the process in which the final product is bundled as a bundle that can be loaded, loaded and transported, as is the case with all the preceding individual processes of the manufacturing process.

    In the process of exploring the method of stacking modules, we used to focus on the problems that occurred during the transportation from the manufacturer to the customer and try to solve the problems with the packaging technology. As a result, streamlined manufacturing requires the return of the stacking process or the return of the stacking preparation from the packaging site to the final manufacturing site.

      In the final stage of solar module manufacture, the module is affixed to its frame. The pasting process includes a so-called “curing stage” that lasts for a relatively long time after a so-called short “holding stage” in which some pressing force is applied.

      According to the invention, it should be possible to make the module already stackable in this curing stage by adding the module already in the stack holding system. Here, the stack holding system not only rationally loads the module bundles at the manufacturer's site, but also requires no additional expensive packaging means, and can be safely installed on the transport means and safe for customers. It is guaranteed that it will be transported.

      Basically, two forms of bundles are possible and common for mounting and transporting photovoltaic modules or solar thermoelectric planar collectors. That is, stacking of horizontal positions and stacking of vertical positions.

      In the case of horizontal stacking, the utilization surface of the module can be either up (sunny side up) or down (sunny side down).

      In the case of vertical stacking, modules with a long rectangular format can basically be positioned vertically on the long side (upright) or vertically on the short side.

      The form of stacking in each case depends on various factors, such as module size, weight, format, pallet dimensions used, the nature of the manufacturer's on-site path transfer or load transfer technology Or the maximum loading height utilization of the transport vehicle.

      An important object of the present invention is a unified, material saving and reusable retention system over as many loading and transport cycles as possible, both horizontally stacked and vertically stacked. It was to provide a retention system that can also be used in form.

In addition, the following requirements should be met:
The individual parts of the reusable retention system should be configured as compact, easy to handle and lightweight as possible, so as not to burden the return from the customer to the manufacturer .
・ Molded products must be able to be exposed to high loads. The reason is that, at least in the case of horizontal stacking, the entire module stacked up and down should be accommodated by the holding system and attached to the pallet.

      Individual moldings of the holding system must be installed in time before the original stacking process of stacking individual modules on the frame, rather than only in the original stacking process. . The restraining device is released from the frame when the attached molded article lifts the module, tilts the module from horizontal to vertical, or rotates the module 180 degrees. It works to stay connected to the frame without.

      These requirements have resulted in the concept of a retention system for horizontally or vertically stacking photovoltaic or solar electronic planar modules. This holding system consists of individual molded parts made of plastic produced by a die casting method. These molded products can be connected to a stable vertical column or horizontal bar by mechanical meshing and by restraining the module frame.

      In many places, solar modules are still individually wrapped in conventional cardboard disposable packaging for delivery to customers. Often, solar modules are reinforced with corrugated cardboard, tension members or styrofoam disposable members having a corresponding format to protect corners and edges. The individually packaged modules are bundled into a bundle by a tension band and are carried by a carrying plate. The module is unpacked by the recipient. The enormous amount of packaging waste generated at that time must be discarded according to the type.

      In contrast, U.S. Patent No. 6,057,051 discloses an evolved, reusable modular plug-in system for safe loading during transport of horizontally stacked photovoltaic modules. Here, the system is exclusively composed of a separate vertically removable load post. Each of these pillars is provided at the top and bottom and is inserted into each other, and each of the pillars is composed of a molded product portion constituting the pillar. Here, each of these molded product parts, on the side facing the photovoltaic module to be transported, by a carrying profile that absorbs the load as a mounting device for the photovoltaic module, One or more journals or one spring is provided on the upper side or the lower side, and a hollow space for accommodating one or more journals or a groove for receiving the spring is provided on the lower side or the upper side. In view of the purpose of this system and the structural features of this system, this system is exclusively suitable only for stacking photovoltaic modules in a horizontal position. This system can only be installed during the original stacking process. The reason is that the photovoltaic modules with individual frames are loaded or hung from above on the carrier profile of the molded part that is stacked and precisely positioned. Inserting the individual molded parts sideways into the individual framed modules can be done before the actual stacking process, ie during the final stage of module production (curing stage for frame application). Is impossible due to Because there are no restraints on the module frame, the molded part resulting from the system can be released or dropped when the module is lifted, tilted, or rotated from the module frame. Therefore, Patent Document 1 does not satisfy the requirements for vertical stacking of solar modules with frames.

European Patent Publication No. 1617485

A retaining system for photovoltaic or solar electronic solar modules with a frame that can be stacked horizontally and vertically, which is very material-saving and reusable over repeated use cycles. It has been found that the system can be provided if it is integrally molded and consists of molded parts that can be connected by constraints on the module frame or by vertical columns or horizontal bars. These molded articles have the following important features for the present invention.
• The molded part has a profile-stable vertical wall ("in standing position"). This vertical wall is configured as a profile that is closed or open on one or both sides and is preferably serpentine.
The vertical wall has one or more spring-loaded fingers, each comprising at least one restraining device for snap-fitting to the profile of the module frame on one horizontal peripheral edge thereof; Yes.
On the two horizontal perimeters, the vertical wall further comprises a gear train or gear fitting opening for mechanical engagement with the adjacent moldings.
-On the other of the two peripheral edges in the horizontal direction, the vertical wall has a contact surface for accommodating the front side of the module frame, and a gear fitting for mechanical meshing with an adjacent molded product With openings or gear trains, and possibly also with one or more spring-loaded fingers for a snap fit to the profile of the module frame.

      In addition, the following optional additional or secondary features characterize the configuration of the retention system according to the present invention.

[Component Location]
When horizontally stacking solar modules whose usage surface is facing upward ("the solar surface side is upward"), one or more restraining spring-type fingers with restraining devices and a row of gear fitting openings , Provided on the lower peripheral edge in the horizontal direction of each molded product. On the other hand, the abutment surface (“solar surface side”) for housing on the front side of the module frame is optionally provided with an additional restraining device, and is mechanically engaged with an adjacent molded product. A gear train is provided on the upper peripheral edge of each molded product.

      When the solar modules are stacked horizontally with the usage surface down (“solar surface down”), the abutment surface for accommodation on the front side of the module frame may be fitted with additional restraining fingers, possibly with a gear fit. The row | line | column of a joint opening part is provided in the horizontal direction peripheral part of each molded article. On the other hand, one or a plurality of forced spring type fingers provided with a restraining device and a gear train for mechanical meshing with an adjacent molded product are provided on the upper peripheral edge of each molded product. .

      In the case of stacking solar modules vertically, it is possible to use molded products made with the same concept as horizontal “sun-up” or “sun-down” stacks.

[Molding of molded products]
The molded product of the holding system according to the present invention can be configured as a square rectangular member. In this case, the molded product surrounds the corners of the module frame after lateral insertion. This corner has a spring-finger with a restraining pin, for example, facing diagonals or provided in two squares, with a horizontal peripheral edge provided for it. Each finger fits directly into a corner or corner area of the module frame.

      In the embodiment with a single finger, the restraining pins present at the finger ends are formed as square corners on the side facing the module frame. The reason is that the fingers fit directly into the inner corners of the frame profile.

      In an embodiment with two fingers, the constraining pin present at the end fits into the straight inner edge of the frame profile near the corner and is therefore chamfered perpendicular to the straight line. Each pin is restrained to slide without resistance on the back of the module frame when the finger bending stresses are built and mated at the same time and when the fingers bounce back to their original unstressed position. The pin is formed to be inclined so as to taper to the “finger tip” in the area of its own sliding contact surface.

      The molded product of the holding system according to the invention can likewise be formed as a rectangular part. In this case, the molded product is fitted to the side surface of the module frame for the purpose of restraining at a desired place. These moldings preferably comprise two spring-loaded fingers on the horizontal peripheral edge provided for this purpose. Each of the fingers has a constraining pin that is chamfered in a straight line and is inclined toward the tip.

      The question of whether to use a corner variant or a rectangular side variant or possibly a combination thereof is not only a matter of saving material. This question depends on the format and weight of the photovoltaic or solar electronic module to be retained. Manufactured by horizontally stacking bundles that can stably transport up to 30 modules after inserting a rectangular holding molded product into the corner of the module frame by testing using commercially available standard size solar modules I know you can. For special modules in rectangular format, two additional rectangular system moldings are additionally mounted on the long side of each module frame, so that unwanted folding does not occur in the module when stacked horizontally It is recommended.

      The question of whether to use a molded product with one or more constraining fingers attached to only one horizontal plane, or to use a molded product with constraining fingers in two horizontal planes, is generally about each module profile. Depends on the molding. In almost all cases, the molded product may be used with one or two restraining fingers in only one horizontal plane in order to securely hold the molded product in the module frame. This embodiment is preferably used.

[Vertical wall molding]
As a further feature of the holding system according to the invention, the profiled vertical walls of the individual moldings are configured as complete profiles on one or both sides, or as “open” profiles. Due to the demand for suitable materials, open profiles are preferred here. In order to fully protect the retention system against intervention, in particular against the dynamic shear forces that occur when it is transported on the road, the profile of the vertical wall is preferably formed in a serpentine shape. Here, the meander is a curved profile. That is, it can be a profile with a circular or elliptical meander. Alternatively, the meander may be a profile having a rectangular line, for example, a square / square, trapezoidal or parallelogram shaped line. All these profile features form a vertical box, which is characterized by providing mechanical interlocking with the adjacent molding. In order to increase the connection strength of the profiled vertical wall, this vertical wall is additionally stabilized by one or more horizontal webs, for example a horizontal web provided at half the height of the molding Has been.

[Horizontal peripheral edge with gear train]
Each profiled vertical wall terminates in a web or plate in one of its two horizontal planes. This web or plate completely covers the opening of the profile. The end plate is provided with a gear train. This gear is used for fitting to the profile fitting opening of each adjacent molded product. The position and shaping of the gear is here adapted to the shape of the vertical wall, so that the gear follows a vertical box (for example in a circular, elliptical, trapezoidal or parallelogram shape), or It is formed as a three-part or multi-part journal or a star-shaped journal. Here, the journal is fitted to the gear fitting opening of the adjacent molded product with accurate positioning. In order for the gear to slide easily into the gear fitting opening, the gear is tapered in all directions in its end region.

[Horizontal end with gear fitting opening]
On the other horizontal surface of the profiled vertical wall, each molding is only partially covered, leaving a corresponding number of openings open. This opening is provided for fitting to an adjacent gear. The position and molding of the gear fitting opening is now along the form of a vertical wall, whereby the gear follows the vertical box underneath it (for example, circular, elliptical, Trapezoidal or parallelogram shape).

[Applicable lip to gear fitting area]
Adjacent moldings where the horizontal outline of each gear of the same shape is provided correspondingly to seat in the gear fitting opening in a “free play” state where the gear is positioned safely and accurately It is advantageous that it is slightly smaller than the vertical housing next to. This difference is counterbalanced by the provision of a gear-fitting area for each vertical housing with two or more horizontal lips for meshing. This lip ensures an accurate and play-free seating of the gears.

[Notch for contact of tension band]
The gear train on the other horizontal plane of the molded product, and thus the gear fitting opening, is interrupted by a notch ("gear gap"). This notch allows the tensioning band to abut for safe transport of the module bundle after the completed stacking process. In the case of a square-shaped holding molded product to be inserted into the corner of the module, these notches are directly present in the corner region. As a result, the module bundle can be stretched diagonally in a cross shape or parallel to the sides of the module bundle. In the case of a rectangular molded product for insertion into the side of the module, the notch is in the center of the molded product.

[Abutment surface for the front side of the module frame]
On one of the two horizontal surfaces of the molded product, a horizontal web or a plate for closing the corner area, or a so-called “contact shoe” is provided. These plates or “abutment shoes” are used to accommodate the front side (“sun surface”) of the module frame. These form on the opposite side of the module an extension of the peripheral edge of the horizontal profile with gears or gear fitting openings.

      These abutment surfaces are preferably reinforced with flat lips, in order to improve the static and dynamic loadability of the horizontal peripheral edge of the molded product, especially in the contact area with the module frame.

      As described above, the horizontal web or plate used for housing the “sun surface” of the module frame may be configured with one or more restraining fingers.

[Abutment surface with spring-type fingers and restraining pins]
On the other horizontal surface of the molded product, the horizontal perimeter on the surface facing the module forms a horizontal abutment surface that closes the web shape and / or corner area. One or a plurality of forced spring fingers each having a restraining pin are connected to the contact surface. These are used to store and restrain the molded product on the back surface of the module frame. These abutment surfaces and spring-loaded fingers are also preferably reinforced by flat lips.

[Molded product / Durability / Recycling]
The molded product forming the holding system according to the present invention is a plastic injection molded product, preferably made of polypropylene. The molded product is designed as a part that can be used repeatedly for 20 times. Thereafter, the molded product is recycled.

It is provided on the upper peripheral edge (5) of (1). The molded article (1) provided in this configuration is suitable for both horizontal stacking of solar modules at the position "sun face up" and vertical stacking of solar modules.

      FIG. 4 shows a cross-sectional view of the molded product (1) according to the present invention. Here, the molded product is inserted into the corner of the module frame at a position where the sun surface is below. That is, the solar light utilization surface is directed downward. In this case, a contact web (10) for housing the module frame is provided on the lower horizontal surface on the solar light utilization surface (solar light utilization surface) of the module. A contact plate (5) for accommodating the corners of the module frame on the rear side and a gear (6) for meshing with an adjacent molded product are provided on the horizontal peripheral edge (5) on the upper side of the molded product (1).

      FIG. 5 shows a perspective view of the molded product (1) according to the present invention configured as a corner portion. This molded product is inserted into the frame corner of the solar module. In this case, the vertical wall (2) is formed as a meandering profile meandering in a curved shape. The gear fitting opening (9) and the gear (6) for meshing with the adjacent molded product are configured in a circular shape correspondingly. In this illustrated spirit, the molded article (1) provided on the two horizontal peripheral edges comprises two spring-type fingers (11) each having a restraining pin (12). Each of the restraining pins fits in the frame in the immediate vicinity of the corner of the module frame.

      FIG. 6 shows a molded product (1) composed of rectangular side portions. This molded product should be inserted into the frame side of the solar module. In the embodiment shown here, the molded product is configured adjacent to one of the horizontal peripheral edges having two spring-loaded fingers (11) with restraining pins (12). In this constraining pin, the other peripheral edge in the horizontal direction includes only a single constraining pin (11), (12).

      FIG. 7 shows cross-sectional views of various embodiments of molding profiled vertical walls (2). The profile has a vertical wall closed on both sides with an inner web (2.1), as a vertical wall (2.2) open on one side, or a curved or rectangular meander line (2.3) It is basically possible to implement as a serpentine profiled vertical wall open on both sides. An open profile configuration (2.3) with curved or rectangular meander lines is preferred in order to minimize the material and weight of the interlocked product according to the present invention.

      FIG. 8 relies on the variant shown in FIG. 7 and shows a corresponding embodiment of a gear fitting opening to one of the two horizontal peripheral edges of the molded product according to the invention. . Embodiment variants 9.1, 9.2 and 9.3 are each adapted to the vertical profile configuration variant shown in FIG.

      FIG. 9 is based on the variant shown in FIG. 7 and is provided with gears (6.1), (6.2), ( A corresponding embodiment for the molding of 6.3) is shown. The form of the gear can be configured to accurately follow the form of the gear fitting openings (9.1), (9.2), and 9.3) shown in FIG. However, the gear form may also be configured as a three-piece, multi-piece or star-shaped journal (14). In order to allow the gear to slide easily into the gear fitting opening, the gear is configured to taper in all directions in its end region (15).

      FIG. 10 shows in detail a cross-sectional view of the vertical housing (16) constituted by the profiled vertical wall (2), taken along the gear fitting area. The outer size of the gear (6) is slightly smaller than the inner size of the vertical housing (16).

These lips function for precise seating of the gear (6) in the gear fitting area of the housing (16).

      FIG. 11 shows in detail one spring-type finger (11) each having a restraining pin (12). The restraining pin (12) shown in the left part of the figure is provided for snap-fit directly to the corner of the module frame and is therefore chamfered square in the contact area with the frame. The restraining pin (12) shown in the right part of the figure is provided for snap-fitting to the linear region of the module frame, and thus is linearly chamfered in the contact region with the frame. In both cases, the restraining pin is configured to taper toward the “finger tip” so that it can slide over the back of the module frame with as little resistance as possible.

      FIG. 12 shows a module bundle (19) stacked horizontally by the holding system according to the present invention and a module bundle (20) stacked vertically by the same system.

Horizontal stacking at the “sun-down” position From the module manufacturer's side, a 100 × 170 cm standard format framed photovoltaic module is still in the final stages of manufacture, In the adhesive curing stage after the aluminum frame profile is bonded, it is bundled in the most reasonable manner and the modules are stacked horizontally, each with 36 shelves on a suitable plate for 2 shelves. It was required to load the plate on the plate shelf and then ship it to the customer as it was.

      In the above-described curing stage of the adhesive, the module is in the “sun face down” position. That is, the back side is facing up. A molded product of the holding system according to the present invention configured as a corner portion was inserted into each of the four corners of the module with the frame from the side direction until a restraining snap fit was achieved. This was a process of a few seconds. The corner portion was configured as in claim 4. That is, a horizontal contact surface for accommodating the “sun surface” of the module frame and a row of gear fitting openings are provided on the lower peripheral edge of each molded product. On the upper horizontal peripheral edge, a spring-type finger having a constraining pin provided on a diagonal line and a gear train for mechanical engagement with an adjacent molded product were provided. The first module provided with the corner portion was lifted and placed on the plate by the suction gripper. All the second and subsequent modules provided with corners were mounted thereon. Here, the gear of the corner | angular part which exists on each was fitted to the gear fitting opening part which exists on the lower side of the corner | angular part mounted on it. This meshing formed four stable columns through which the module load was distributed to the plates.

      For transport to customers, the plate bundles were wrapped with appropriate files and stretched on the plates with tension bands.

      On the customer side, the modules have been transshipped into a small set of 12 each for the time being. That is, it was divided into three plates. For this purpose, the individual modules, together with the corners present there, were each raised by a manual suction gripper and transferred to a new plate.

      After transport to the construction site, each module was manually removed from the bundle. The corners were removed from the frame only shortly before installation of the individual modules. This is because the corners provide effective corner and edge protection when the module is handled at the construction site, for example, carrying the module or placing it on the floor.

Horizontal stacking at the “Solar Top Up” position In other module manufacturer's brokerage, similarly, standard size solar modules were to be stacked horizontally on the plate. Due to logistical requirements, the stacking was to be done "in the sun" position. That is, the solar light utilization surface is facing upward. The same stacking method as in Example 1 was also performed here. What was used, however, was the molded article according to the invention as shown in FIGS. 1 and 2 and as defined in claim 2. That is, a spring-type finger with a restraining pin and a row of fitting openings are present in the horizontal peripheral edge on the lower side of each molded product, on the other hand, for accommodating the “sun surface” of the module frame A gear train for mechanical meshing between adjacent abutting surfaces and adjacent molded products is provided on the upper peripheral edge of each molded product.

Horizontal stacking in the corner and side portions The very long special embodiment solar modules of 260 × 100 cm were to be stacked horizontally.

      This problem should be basically solved in the same manner as described in Examples 1 and 2. However, it has to be avoided that the module bends unacceptably towards the center due to its long long side and in some cases breaks during transportation on the road. Thus, the module is not only provided with corner portions according to the present invention, but additionally in the middle of the long side of each module, the rectangular side portion according to the present invention as shown in FIG. Inserted into the frame. In addition to the prisms constituted by the corner portions, support columns provided in two lateral directions were thus provided. This support column reduces the load on the module bundle even in the central region.

Vertical stacking At the request of the module manufacturer, 20 solar modules each having a surface area of 1.7 square meters were to be stacked on a suitable plate in a vertical position. The actual experiment confirmed that the corner portions according to the present invention used in Examples 1 to 3 can be stacked both in the horizontal direction and in the vertical direction. Lifting and tilting in the vertical direction of the module with corner portions according to the invention is performed by a programmable suction gripper. In order to mount the first module vertically on the plate and add the second two modules to the plate, a vertical support device having a simply inclined vertical surface is used. This support device is no longer necessary when adding all further modules.
