The modules can be individually mounted to the assembly and stabilized thereon, before being securely connected to the assembly, for purposes of component part replacement or initially assembly. In some embodiments, the modules consist essentially of a gear and motor module, an expander module, a power supply module, an internal mounting frame module and a cutter module.
This application is a divisional of U.S. patent application Ser. No. 15/471,570, filed on Mar. 28, 2017, which claims the benefit of U.S. Provisional Patent Application Ser. No. 62/314,384, filed on Mar. 28, 2016, which is incorporated herein by reference in its entirety.
BACKGROUND 1. Technical FieldThe present disclosure relates to dunnage machine assemblies for generating cushioning material, and in particular, to dunnage machine assemblies with modular components and methods for assembly thereof.
2. Description of Related ArtU.S. Pat. Nos. 8,501,302 and 8,708,882 show example prior art dunnage systems, which are helpful for providing context for understanding the present disclosure, both of which are incorporated herein by reference in their entireties.
Many commercially available dunnage machines that are currently available on the market tend to be large and heavy. Shipping entire dunnage machines for repair is labor intensive and/or expensive. Also, dunnage machine parts are often complicated to repair or to remove for repair/replacement. As a result, maintenance is often difficult, complicated, and expensive.
BRIEF SUMMARYIn some embodiments, a dunnage machine assembly is provided in discrete modules that, when assembled together, include all components necessary to expand sheet stock material and process the sheet stock material to form cushioning material or dunnage. The discrete modules can consist essentially of an internal mounting frame module, electronic control/power supply (E-box) module, gear and motor module, cutter module, and expander module. Thus, in such embodiments, the entire dunnage machine assembly exhibits traits of portability with easy assembly and disassembly for any component of the dunnage machine that may need repair and/or replacement. That is, for example, a repair or replacement of any component of the dunnage assembly may comprise simply removing the module within which a component is contained, and repairing the component or shipping the particular module away for repair, while replacing the module with a replacement module in operative condition. The replacement module may be held in inventory so that there is no delay in repair.
Despite the benefits of providing discrete modules to house various components of the dunnage assembly, handling of each of the discrete modules by, for example, a single individual may be difficult due to their size and weight (e.g., a motor combined with the moveable components that it drives). However, various methods and structures of the present disclosure are provided to aid a user in removing and/or mounting and connecting the modules together. For example, in some embodiments, the gear and motor module as referenced above may be mounted on the internal frame module by being hung on the internal frame module in stable position, then a user may securely fasten the gear and motor module to the internal frame module without otherwise having to stabilize the module while fastening. As such, in some embodiments, a single individual may be able to efficiently replace modules, or otherwise assemble them together, with relative ease.
In the present description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the disclosure. However, upon reviewing this disclosure one skilled in the art will understand that the various embodiments disclosed herein may be practiced without many of these details. In other instances, some well-known structures and materials of construction have not been described in detail to avoid unnecessarily obscuring the descriptions of the embodiments of the disclosure.
In the present disclosure, to the extent the terms “about” and “approximately,” are used, they mean±20% of the indicated range, value, or structure, unless otherwise indicated. In the present description, the terms “a” and “an” as used herein refer to “one or more” of the enumerated components. The use of the alternative (e.g., “or”) should be understood to mean either one, both, or any combination thereof of the alternatives. As used herein, the terms “include” and “comprise” are used synonymously, and these terms and their variants are intended to be construed as non-limiting. The definitions in this paragraph are intended to apply throughout this disclosure unless otherwise expressly stated.
In some embodiments of the present disclosure, a dunnage machine is provided that includes modules that can easily be assembled together, as well as disassembled, even by a single individual. Each of the module can be individually fabricated, repaired, tested, assembled, and “connected” to other modules of the dunnage machine.
In various embodiments, each of these modules may be easily connected together when the internal assembly 10 is being assembled, either initially, or for parts replacement. When the internal assembly 10 needs to be repaired or parts need to be replaced, the internal assembly 10 may be disassembled by, for example, disconnecting (e.g., unscrewing various screws) and pulling apart the various modules as needed.
The internal assembly 10 includes a rear section 12, which is the rear of the internal assembly 10 facing a direction from which sheet material may be fed into the internal assembly 10 via the expander forming module 60. Opposite from the rear section 12 is a forward (or front) section 14 facing a direction in which cushioning material may be outputted from the internal assembly 10 through cutter module 50. Note that the internal mounting frame module, E-box module, expander module, gear and motor module, and cutter module, each may be described as having a rear section 12 and a forward (or front) section 14.
Note that for ease of illustration and explanation, various relative spatial terms such as “longitudinal,” “lateral,” “vertical,” “top,” and “bottom” may be used in the following description. Unless the context expressly indicates otherwise, the term “longitudinal” as used herein refers to an axis running generally parallel to the line that forms arrow “Z” in
The E-box module 30 may include various electronics for controlling and/or for providing power to various motors (e.g., electric motors for the cutter module 50 and the gear and motor module 40) that may be included in the internal assembly 10. The electronic components of the E-box module 30 may be covered and protected by an external housing of the E-box module 30.
Referring to
The two mounting fins 410 each have a top end and a bottom end that is opposite of the top end, the bottom ends of the two mounting fins 410 being attached to, or formed on, respective upper parallel longitudinal frame members 22a, 22b of the internal mounting frame module 20, projecting upwards therefrom. In some embodiments, one or more cables 404 may hang from the bottom of the gear and motor module 40 for controlling and/or providing electric power to the gear and motor module 40. Once the gear and motor module 40 is mounted to the internal mounting frame module 20, as illustrated in
In various embodiments, the gear and motor module 40 may be configured to pull sheet material that is fed into and passes through the expander module 60. In various embodiments, the gear and motor module 40 may further be designed to compress, or stitch, at least a portion (e.g., a longitudinal portion or strip) of sheet material outputted by the expander forming module 60, as will be appreciated by those skilled in the art after reviewing this disclosure.
Similarly, in some embodiments, disposed just below each holding stud 502 of each mounting sidewall 510 is a corresponding fastening member aperture 508 that aligns with a corresponding aperture 506 of the mounting fins 410 when the holding stud 502 is deposited/sits in the holding notch 504, and a rear portion 40a of the gear and motor module 40 abuts against the internal mounting frame 40 (e.g., a lateral frame member 27a thereof). When corresponding apertures 508, 506 are aligned a fastening member 402 (e.g., screw) may be threaded, or otherwise coupled, through the apertures to securely connect the gear and motor module 40 to the internal mounting frame module 30.
The holding notch 504 and the holding stud 502 described above may prove to be particularly useful when, for example, only a single individual is securing the gear and motor module 40 onto the internal mounting frame module 20, or removing the gear and motor module 40 therefrom. That is, the gear and motor module 40, which may include a motor for driving the various mechanical components (e.g., gears and forming members) of the gear and motor module 40, may be relatively heavy. However, by simply depositing the holding studs 502 of the gear and motor module 40 into the holding notches 504 of the internal mounting frame module 20, a single individual user may hang the gear and motor module 40 before adjusting (inserting) the fastening members 402 to connect the gear and motor module 40 to the internal mounting frame module 20, and conversely, when the user is removing the gear and motor module 40, the fastening members 402 may be removed completely before handling the heavy module (e.g., lifting it from its hanging position on the holding notches 504), as will be appreciated by those skilled in the art after reviewing the present disclosure.
Referring to
In various embodiments, the holding notches 702 of the cutter module 50 and the stopping studs 704 of the gear and motor module 40 may be particularly useful for mounting and securing the cutter module 50 to the gear and motor module 40. In particular, the holding notches 702 and the stopping studs 704 may be used to properly align the cutter module 50 with the gear and motor module 40 so that the fastening members 606 used to secure the cutter module 50 to the gear and motor module 40 may be aligned with corresponding holes (606′, 606′ disposed on the cutter module 50 and the gear and motor module 40. Moreover, in some embodiments, after a user aligns the cutter module 50 with the gear and motor module 40, and rests the holding notches 702 on the stopping studs 704, the cutter module 50 can rest in alignment (be mounted) without a user holding the cutter module 50 against the gear and motor module 40, and the user's hands may be free to apply the fastening members 606 to secure the cutter module 50. Alternatively, the user can use a single hand to press the cutter module 50 against the gear and motor module 40 with the modules aligned, and then apply the fastening members 606.
Referring to
In various embodiments, the expander module 60 has a rear section 12 and front section 14 and an opening provided therethrough for receiving sheet stock material for expanding the sheet stock material in the expander module 60 before the sheet stock material is pulled through the gears in the gear and motor module 40, as will be appreciated by those skilled in the art after reviewing this disclosure. In some embodiments, the expander module 60 includes a rear section base plate 808, forming a bottom wall leading to a feed entrance of the expander module 60.
Turning now to
Note that although process 1100 appears to show various operations being performed in a specific sequence, those having ordinary skill in the art after reviewing the present disclosure will recognize that in various embodiments, one or more of the illustrated operations may be performed in any sequence with respect to the other illustrated operations, or may be performed concurrently. For example,
In some embodiments, the dunnage machine 1010, includes all components necessary to expand sheet stock material and process the sheet stock material to form cushioning material or dunnage. That is, aside from a sheet stock supply system to deliver the sheet stock material to the dunnage machine 1010, and a power source supply to the E-box of the dunnage machine, the internal mounting frame module 20, E-box 30, gear and motor module 40, cutter module 50, and expander module 60, can provide essentially of all modules necessary to process sheet stock material within the dunnage machine 1010 to form dunnage (e.g., cushioning material). Thus, in some embodiments, the entire dunnage machine 1010 exhibits traits of portability with easy assembly and disassembly for any component of the dunnage machine 1010 that may need repair and/or replacement. That is, for some disclosed embodiments, there are only five (5) modules, and those modules encompass all parts of the dunnage machine (except the sheet stock supply system if any). Thus, a repair or replacement of any component of the dunnage machine 1010 may comprise simply removing the module 20, 30, 40, 50, 60 within which a component is contained, and repairing the component or shipping the particular module away for repair, while replacing the module with a replacement module 20, 30, 40, 50 or 60, in operative condition. Although the examples illustrate five modules, various embodiments can include a dunnage machine consisting essentially of two or three modules, or up to eight or more modules, which modules still encompass all required mechanical and electrical parts for processing dunnage in a dunnage machine, excluding the sheet stock supply system (e.g., the supply systems can be considered separate from the dunnage machine and part of the dunnage system). In such alternative embodiments, one or more of the modules expressly described above and illustrated in the
