The present disclosure relates generally to vehicle assembly processes and, more specifically, to systems for use in preheating elastomeric weather strips to facilitate their installation onto a vehicle.
Motor vehicles have many openings covered by swinging panels such as doors, trunks, tailgates, and hatchbacks. Weather strips are used to seal these openings to prevent rain, dirt, mud, noise, external temperatures, and the like from entering the vehicle through the openings. Many known weather strips are fabricated from a pliable material, such as rubber, which enables the weather strip to be compressed to tightly seal any gaps between the vehicle body and its swinging panels. Weather strips are typically manufactured separately from the vehicle body and then forced onto the vehicle, oftentimes manually by a technician, along the perimeter of the openings. Heating rubber is known to enhance its pliability such that in at least some known installation applications, the weather strips are heated prior to being installed onto the vehicle body. Such heating generally requires the weather strips to be preheated in a large heated enclosure positioned along the vehicle assembly line. Heating the interior volume of the enclosure may be costly and inefficient, and may also result in inconsistent temperature distribution across the interior volume. In addition, the enclosure may have a large physical footprint and be immobile, which limits its versatility and use.
In one aspect, a system for use in processing rubber seals is provided. The system includes at least one insulated cabinet including a first end, a second end, and a first dimension defined therebetween. The at least one insulated cabinet further includes a side wall defining an interior of the at least one insulated cabinet, and an access window defined in the side wall. A cover is configured to at least partially restrict airflow through the access window. A hanger is coupled at the first end of the at least one insulated cabinet, wherein the first dimension is oriented to define a height of the at least one insulated cabinet such that a plurality of the rubber seals are suspendable from the hanger within the interior. A heater is thermally coupled to the at least one insulated cabinet, wherein the heater is configured to heat the interior to greater than a predefined temperature.
In another aspect, a system for use in processing rubber seals is provided. The system includes at least one insulated cabinet including a first end and a second end, defining a height dimension therebetween, and a depth dimension. The at least one insulated cabinet further includes a side wall defining an interior sized to receive a plurality of the rubber seals therein, and an access window defined in the side wall. A cover is configured to at least partially restrict airflow through the access window. A hanger is coupled at the first end of the at least one insulated cabinet, wherein the hanger is oriented to extend in the depth dimension such that the plurality of the rubber seals are stackable on the hanger in the depth dimension. A heater is thermally coupled to the at least one insulated cabinet, wherein the heater is configured to heat the interior to greater than a predefined temperature.
In yet another aspect, a system for use in processing rubber seals is provided. The system includes at least one insulated cabinet including a first end and a second end, defining a height dimension therebetween, a depth dimension, and a width dimension. The depth dimension and the width dimension are shorter than the height dimension. The at least one insulated cabinet further includes a side wall defining an interior sized to receive a plurality of the rubber seals therein, and an access window defined in the side wall. A cover is configured to at least partially restrict airflow through the access window. A hanger is coupled at the first end of the at least one insulated cabinet, wherein the hanger is oriented to extend in the depth dimension such that the plurality of the rubber seals are stackable on the hanger in the depth dimension. A heater is thermally coupled to the at least one insulated cabinet, wherein the heater is configured to heat the interior to greater than a predefined temperature.
The embodiments described herein relate generally to systems for use in preheating rubber weather strips to facilitate their installation onto a vehicle. Trunk seals, and rubber weather strips in general, require less force to apply when they are exposed to repeatable and consistent heat. At least some weather strips are pre-fabricated as closed-loop structures sized to fit the perimeters of the vehicle openings to be sealed. The weather strips are generally flexible, but at room temperature may be difficult to install onto a vehicle. Accordingly, the systems described herein include one or more insulated cabinets that are adapted to retain heat and store a plurality of weather strips therein. The cabinets include a side wall that defines an interior, and an access window that provides access to the interior. A hanger coupled within the interior is capable of receiving multiple weather strips and holding them within the interior. In addition, the cabinet is sized to store weather strips suspended from the hanger therein, while also being limited in size to enable the interior to be heated in a consistent, evenly distributed, and efficient manner. Because of the limited capacity of the cabinets, multiple cabinets may be used to preheat enough weather strips required to complete a job, for example. Accordingly, multiple cabinets may be mounted on a base, defining a system that is lightweight, portable, and dynamically versatile.
In use, the preheated weather strips may be retrieved from the insulated cabinets through the access window. The access window may be at least partially sealed with a cover such that heat is retained within the interior of the cabinet. The cover is also designed to enable the weather strips to be retrieved from the cabinets in a quick and efficient manner, while also being self-sealing for retaining the heat therein. The preheated and now pliable weather strips may then be pressed along the perimeter of a vehicle opening with less force, thereby reducing strain on a technician.
A single insulated cabinet 104 is described below in further detail, but it should be understood that the following is applicable to each insulated cabinet 104 in system 100. In the exemplary embodiment, insulated cabinet 104 includes a first end 108, a second end 110, and a side wall 112 defining an interior 114 thereof. An access window 115 is defined in side wall 112 for providing access to interior 114. Insulated cabinet 104 further includes a cover 116 extending across access window 115. For example, cover 116 may be any self-sealing door, flap, or other physical member that provides selective access to interior 114 while also at least partially restricting airflow through access window 115. Accordingly, cover 116 restricts heated air from escaping interior 114 through access window 115, which facilitates maintaining adequate and consistent heating within insulated cabinet 104 for maintaining rubber seals 102 at a desired temperature. In the exemplary embodiment, cover 116 includes a plurality of strips 118 of material (i.e., a strip curtain) hanging from first end 108 of insulated cabinet 104. Adjacent strips 118 may be overlapping or aligned side-by-side to facilitate sealing access window 115. Accordingly, a technician may gain access to interior 114 by reaching between adjacent strips 118.
Insulated cabinet 104 includes a hanger 120 coupled at first end 108 thereof such that rubber seals 102 are suspendable therefrom. In the exemplary embodiment, rubber seals 102 are closed-loop structures that are flexible and elastomeric at room temperature. Accordingly, rubber seals 102 received on hanger 120 extend in a height dimension H and a width dimension W of insulated cabin 000 when suspended within interior 114. In one embodiment, hanger 120 is coupled to side wall 112, and is oriented to extend from side wall 112 in depth dimension D. Accordingly, a plurality of rubber seals 102 are stackable in depth dimension D on hanger 120 to increase the capacity of insulated cabinet.
Referring to
Dimensions 122, 124, and 126 are also selected such that interior 114 defines a limited volume that may be heated in a consistent, evenly distributed, and efficient manner. For example, in one embodiment, dimensions 122, 124, and 126 are selected to be greater than the dimensions of rubber seals 102 suspended from hanger 120 by no more than a predetermined percentage of the rubber seal dimensions. For example, first dimension 122 may be selected to be no more than about 125 percent, no more than about 120 percent, no more than about 115 percent, no more than about 110 percent, or no more than about 105 percent of suspended length 128 of rubber seals 102. Second dimension 124 may be selected to be no more than about 125 percent, no more than about 120 percent, no more than about 115 percent, no more than about 110 percent, or no more than about 105 percent of suspended width 130 of rubber seals 102. Third dimension 126 may be selected based on a desired capacity of insulated cabinet 104, wherein the capacity of insulated cabinet 104 increases proportionally as third dimension 126 increases. Accordingly, limiting the length of dimensions 122, 124, and 126 facilitates defining a limited interior volume of insulated cabinet 104 that may be heated and maintained at a desired temperature in an efficient and cost-saving manner.
As described above, access window 115 is defined in side wall 112 to provide access to interior 114. Access window 115 may have any size and/or shape that enables insulated cabinet 104 to function as described herein. In the exemplary embodiment, access window 115 extends substantially the entire length of first dimension 122. Accordingly, rubber seals 102 may be selectively received within, and then removed from, interior 114 through access window 115 with minimal effort and enhanced accessibility.
Also as described above, insulated cabinet 104 is heated to enhance the pliability of rubber seals 102 stored therein. Insulated cabinet 104 may be heated by any mechanism or technique that enables system 100 to function as described herein. In the exemplary embodiment, at least one heating vent 132 is defined in side wall 112 for channeling heated air (not shown) into interior 114. For example, a plurality of heating vents 132 may be defined in side wall 112 and arranged and/or aligned in first dimension 122 along side wall 112. Accordingly, as will be described in more detail below, heating vents 132 are arranged to provide substantially uniform heat along the height of insulated cabinet 104.
Insulated cabinet 104 may be fabricated of any material that enables system 100 to function as described herein. In one embodiment, insulated cabinet 104 is fabricated from a non-metallic material such as, but not limited to including, polypropylene, polyethylene, polyvinylchloride, polystyrene, polyethylenetheraphthalate, and polycarbonate. In addition, side wall 112 may have any thickness that enables insulated cabinet 104 to function as described herein. For example, the side wall thickness may be defined within a range between about 0.05 inch and about 0.5 inch, between about 0.1 inch and about 0.5 inch, and between about 0.1 inch and about 0.25 inch. Accordingly, insulated cabinet 104 enables system 100 to be lightweight and portable, and capable of retaining heat therein better than thermally conductive metallic counterparts.
In the exemplary embodiment, first connector 144 includes a port 148 defined therein. System 100 also includes a heater 150 coupled in flow communication with conduit assembly 138 via port 148. Heater 150 may be any device that enables insulated cabinets 134 and 136 to be heated to a desired temperature. In one embodiment, heater 150 generates heated air 152, and channels heated air 152 towards insulated cabinets 134 and 136. Port 148 is configured to receive heated air 152 from heater 150, and conduit assembly 138 channels heated air 152 towards insulated cabinets 134 and 136. Heater 150 may be selectively coupled and uncoupled from conduit assembly 138 to further enhance the portability of system 100. In some embodiments, system 100 also includes a temperature sensor within interior 114 (shown in
The embodiments described herein relate to systems for use in preheating rubber weather strips to facilitate their installation onto a vehicle. The systems described herein include one or more insulated cabinets in the form of polymer columns that are adapted to retain heat and store a plurality of weather strips therein. The cabinet is limited in size to enable the interior to be heated in a consistent, evenly distributed, and efficient manner. Once heated, the preheated weather strips may be retrieved from the insulated cabinets for installation onto a vehicle, sometimes manually by a technician. Heating the weather strips enhances their pliability, such that installation of the weather strips may be achieved with reduced strain and improved ergonomic efficiency for the technician.
Exemplary embodiments of a system for use in preheating rubber seals in preparation for installation onto a vehicle are described above in detail. Although the system is described and illustrated in association with weather strips for use in sealing vehicle openings, the invention is also intended for use with other assemblies as well. Moreover, it should also be noted that the components of the invention are not limited to the specific embodiments described herein, but rather, aspects of each component may be utilized independently and separately from other components and methods described herein.
