More particularly, the present invention relates to a clip separating system, to a kit for assembling the same, to a manufacturing plant provided with such a clip separating system, to clips and corresponding products having being processed accordingly, and to corresponding methods of operating and assembling associated thereto.
Background of the invention: Known in the art are clip separating systems which are typically used in the car industry for individually separating clips from a bulk of accumulated clips so that each clip may be individually picked up by a complementary picking mechanism, and subsequently inserted into a corresponding aperture of a product band, said product band being generally used as a sealing joint in various car portions and the like.
Also known in the art are the various drawbacks and inconveniences associated with such aforementioned conventional systems, namely, but not limited to the following: a) transfer of the clips to be separated is done via a fixed and rigid curved machined component which due to friction and other considerations tends to lead to a jamming of clips and poor feed into the inlet of the separating assembly; b) configuration of a spring-loaded outer moveable component onto an inner fixed component provides for an uneven spring-loaded force throughout the driving path with a greater force felt by the clip at the inlet of the separator which tends to lead to potential obstruction of the clip at the entry point, and weakest force felt by the clip at the outlet of the separator which tends to lead to potential poor positioning and/or securement of the clip prior to being picked up, in addition to requiring an increased driving force necessary to drive the clip from entry to exit of the separator; c) orientation of clips by means of a fixed and rigid curved machined component or rail is not optimal in that a minimal of clips is required in the rail to ensure a proper feed and/or operating of the system to compensate for friction inside the fixed and curved feeding rail; d) a shifting kit is required when a same separator is to be used with two different sources of clips and the shifting action of the shifting kit between the separation action of two different types of clips results in a substantial time delay (i.e. loss of time) that in turn results in a considerable loss of productivity; f) etc. Hence, in light of the aforementioned, there is a need for an improved system which, by virtue of its design and components, would be able to overcome or at least minimize some of the aforementioned prior art problems.

Furthermore, in the context of the present description, it will be considered that expressions such as "inserted" and "insertable", or "connected" and "connectable", or "mounted" and "mountable", may be interchangeable, in that the present invention also relates to a kit with corresponding components for assembling a resulting fully assembled clip separating system (1 ).
In addition, although the preferred embodiment of the present invention as illustrated in the accompanying drawings may comprise various components, and although the preferred embodiment of the clip separating system (1 ) as shown consists of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential to the invention and thus should not be taken in their restrictive sense, i.e. should not be taken as to limit the scope of the present invention. It is to be understood, as also apparent to a person skilled in the art, that other suitable components and cooperation thereinbetween, as well as other suitable geometrical configurations may be used for the clip separating system (1 ) and corresponding components according to the present invention, as will be briefly explained hereinafter and as can be easily inferred herefrom by a person skilled in the art, without departing from the scope of the invention. Broadly described, the present invention, as illustrated in the accompanying drawings, relates to a clip separating system (1 ) to be used for separating clips (3) intended to be individually picked up and subsequently inserted onto components (ex. seals, bands, products, parts, etc.) destined primarily for the manufacturing industry (ex. car industry, etc.). The present clip separating system (1 ) is preferably of simple design and inexpensive to manufacture or assemble. As will be shown hereinbelow, the present clip separating system (1 ) possesses several advantages when compared to conventional clip separating systems known in the art.
More particularly, as can be easily understood by a person skilled in the art when referring to Figures 1 -15, and according to a preferred aspect of the present invention, there is provided a clip separating system (1 ) for separating a clip (3) from an accumulation of clips (3) contained within a feeding assembly (5), the clip separating system (1 ) comprising a separating assembly (7) having an inlet (9) and outlet (1 1 ), the inlet (9) of the separating assembly (5) being operatively connected to an outlet (15) of the feeding assembly (5) for receiving the clip (3) to be separated therefrom, a path (10) being defined between the inlet (9) and the outlet (1 1 ) of the separating assembly (7), the clip (3) to be separated being positively driven along said path (10) via a corresponding driving component (19) of the clip separating system (1 ), the outlet (1 1 ) of the separating assembly (7) being vertically offset (21 ) with respect to the outlet (15) of the feeding assembly (7), as may be better appreciated when referring to Figures 1 1 - 15, for example. Namely, the outlet (15) of the feeding assembly (7) (and/or corresponding inlet (9) of the separating assembly (7)) is disposed along a different plane than that of the outlet (1 1 ) of the separating assembly (7) (and/or corresponding pick up location of the clip (3) by the complementary pick up mechanism). As can be easily understood, any suitable complementary pick up and insertion tool known in the art may be used in combination with the present clip separating system (1 ). According to a preferred embodiment of the invention, the path (10) is defined between a fixed component (23) and a moveable component (25) of the clip separating system (1 ), the moveable component (25) being positioned inwardly with respect to the fixed component (23), and the moveable component (25) having a portion located under the outlet (15) of the feeding assembly (5), as also better shown in Figures 1 1 -15, for example. Preferably, and as also shown, the path (10) of the separating assembly (7) is a substantially arched path, and preferably, about one quarter of a circle, although various other suitable geometric configurations may be used depending on the particular applications for which the present clip separating system (1 ) is intended for, and the desired end results, as can be easily understood by a person skilled in the art. According to another preferred embodiment of the invention, the moveable component (25) is biased towards the fixed component (23), and although various types of biasing forces or configurations may be used for the present system (1 ), the moveable component (25) is preferably spring-loaded towards the fixed component (23), by means of a spring assembly (27) providing a corresponding biasing force, so as to precisely clamp and maintain the clip (3) to be separated in place at the end of the path (10), as can be easily understood by a person skilled in the art when referring to the accompanying drawings.
Preferably, the moveable component (25) is positioned, shaped and sized with respect to the fixed component (23) so that the biasing force acting on the clip (3) being separated increases as the clip (3) is displaced along the path (10) from the inlet (9) to the outlet (1 1 ) of the separating assembly (7). Preferably also, the moveable component (25) is further positioned, shaped and sized with respect to the fixed component (23) so that the clip (3) is deprived of any biasing force when entering the inlet (9) of the separating assembly (7). These preferred features of the system are particularly advantageous in that they enable the clip (3) to be separated to be precisely positioned at the inlet (9) of the separating assembly (7) via a geometrical disposition of the inlet (9) and neighboring components, without the adverse effects of a biasing force at this entry point of the system (1 ), while advantageous using the biasing force progressively increasing as the clip (3) is urged along the path (10) for ensuring that the spring-loaded force acting between the fixed and moveable components (23, 25) will securely clamp and maintain the clip (3) into place, at the end of travel of the driving component (19), when the latter is drawn back to an original position for separating a subsequent clip (3) from the feeding assembly (5), as can also be easily understood by a person skilled in the art when referring to Figures 1 -23.
According to a preferred embodiment of the present invention, the biasing force of the system (1 ) may also comprise a preload being selectively adjustable by means of a corresponding adjustment component (39) (ex. setscrew) of the clip separating system(1 ). It is worth mentioning also that other suitable components, features and/or configurations may be used for providing the present system (1 ) with a suitable preload or adjustment value to the biasing force as a default level, etc.
According to another preferred embodiment of the present invention, and as can be easily understood by a person skilled in the art when referring to Figures 1 -15, the clip separating system (1 ) comprises a transitional area (33) operatively interconnecting the outlet (15) of the feeding assembly (5) to the inlet (9) of the separating assembly (7). Preferably, the transitional area (33) is positioned, shaped and sized for allowing no more than two clips (3) to be accumulated in the transitional area (33) when a clip (3) to be separated is present in the inlet (9) of the separating assembly (7). This is particularly advantageous in that such a configuration of the transitional area (33) is intended to avoid or minimize jamming of clips (3) inside the transitional area (33).
As better shown in Figures 4, 1 1 -15 and 20, and according to yet another preferred embodiment of the present invention, the driving component (19) of the clip separating system (1 ) preferably comprises a pushing component (19a) for pushing onto a midsection (3a) (ex. neck) of the clip (3) to be separated along the path (10) during a driving stroke of the driving component (1 9), and preferably also further comprises a supporting component (19b) for supporting a bottom section (3b) of the clip (3) to be separated along the path (10) during a driving stroke of the driving component (19). Preferably also, the transitional area (33) is further positioned, shaped and sized with respect to a component of the driving component (19) so that accumulated clips (3) in the transitional area (33) shift downwardly by about half of a position for each driving stroke of the driving component (19), and so that accumulated clips (3) in the transitional area (33) further shift downwardly by about half of a position for each retracting stroke of the driving component (19), as can be easily understood by a person skilled in the art when referring to Figures 1 1 -15.
According to a preferred embodiment of the present invention, the driving component (19) is operatively activated by means of a driving cylinder (31 ), such as a pneumatic cylinder (31 ) for example, although other suitable types of actuators and/or controls may be used, as apparent to a person skilled in the art.
As also better shown in Figures 1 1 -14, and according to yet another preferred embodiment of the present invention, the clip separating system (1 ) comprises a fingerstop (35) intersecting the path (10) of the separating assembly (7) and being proximate to the inlet (9) thereof, the fingerstop (35) being positioned, shaped and sized for allowing the insertion/drop of one clip (3) to be separated at a time into the inlet (9) of the separating assembly (7). Preferably also, the fingerstop (35) is rotatably mounted onto the clip separating system (1 ) and spring-loaded so as to allow passage of the clip (3) through the fingerstop (35) along a single direction corresponding to a driving stroke of the driving component (19) of the clip separating system (1 ).
According to yet another preferred embodiment of the present invention, the clip separating system (1 ) or clip separating "assembly" comprises a positioning abutment component (29) for abutting against the moveable component (25) to ensure a minimal distance between the moveable component (25) and the fixed component (23) of the separating assembly, and preferably also, the positioning abutment component (29) is configured to be selectively adjustable within the separating assembly so as to adjustably vary a default minimum distance of passage at the outlet (1 1 ) of the separating assembly (7). According to the present invention, the clip separating system (1 ) also preferably comprises its own feeding assembly (5) having an inlet (13) and an outlet (15), the inlet (13) being configured for receiving clips (3) to be separated from a corresponding source (feeding hooper, vibrating bowl, etc.), and the outlet (15) being configured for dispensing a clip (3) to be separated towards the inlet (9) of the separating assembly (7). A path (14) is preferably defined between the inlet (13) and the outlet (15) of the feeding assembly (5), such feeding path (14) being configured for accumulating a plurality of clips (3) to be separated.
According to the preferred embodiments of the invention exemplified in the accompanying drawings, the feeding path (14) of the feeding assembly (5) is a substantially straight vertical feeding path (or feeding "rail"), and the clips (3) to be separated are allowed to travel freely along the path (14) of the feeding assembly (5) via the effect of gravity, although alternatively, the clips (3) to be separated could be urged forcefully along the path (14) of the feeding assembly (5) via a corresponding and suitable driving force, as can also be easily understood by a person skilled in the art.
According to a preferred embodiment of the present invention, the cross- sectional configuration of the feeding rail (14) of the feeding assembly (5) is complementary to that of a bottom portion of the clip (3) to be separated, and is thus preferably "T-shaped" (or at the very least "L-shaped"), as can be easily understood when referring to Figures 3, 7, 8, 12, 13, 15 and 21 . It is worth mentioning however that other suitable geometrical configurations may used so as to properly receive, accumulate, align, guide and/or feed a plurality of clips (3) into the present clip separating system (1 ), as can be easily understood by a person skilled in the art.
The present clip separating system (1 ) is also intended to be used with a plurality of different types of clips (3) or attachments. The clips (3) each preferably comprise components selected from the group consisting of at least one base, a neck and at least one wing, as can be easily understood when referring to Figures 24-30, and more particularly Figures 31 -35. Namely, Figures 31 -35 exemplify different components and features of a possible clip (3) that may be used according to the present invention. Preferably also, the orientation of each base of the clip (3) is substantially perpendicular to the orientation of a corresponding wing of the clip. Each base of the clip (3) comprises at least one retention surface, and preferably a pair of such retention surfaces, as better exemplified in Figures 24-35. Each clip (3) may be surface coated, and/or may be provided with a complementary sealing component, such as an O-ring provided around the neck of the clip (3), for example.
According to a preferred embodiment of the present invention, the path (10) and corresponding outlet (1 1 ) of the separating assembly (7) are configured so that the base (3c) of a separated clip (3) is orientated in a substantially vertical manner when maintained in place at the outlet (1 1 ) of the separating assembly (7) prior to being picked up by a complementary picking mechanism, as exemplified in Figures 1 1 -15, for example.
Preferably, the neck of the clip (3) is substantially the same length as the thickness of the aperture (41 ) of the band (43) onto the clip (3) is to be mounted to ensure a substantially waterproof seal between the band (43) and the clip (3), when the latter is mounted onto its corresponding aperture (41 ). Indeed, the clip (3) is intended to provide a substantially waterproof joint, and may be used for various different components of a car, whether joints found in car doors, between the hood and a radiator, etc.
According to another aspect of the present invention, there is also provided a clip separating system (1 ) comprising both a feeding assembly (5) and a separating assembly (7). As can also be easily understood by a person skilled in the art when referring to Figures 1 -23, the present clip separating system (1 ) may be used with a "single" feeding/separating assembly (5,7) or with a plurality thereof, such as a pair of first and second feeding assemblies (5) each being configured for dispensing a given clip (3) of a certain type (shape, size, color, etc.) or not (for example, both could be feeding two separate streams of clips (3) of the same nature for an increased total output, etc.), as well as with a pair of corresponding first and second separating assemblies (7), in which case the components and features of each assembly (feeding (5), separating (7), etc.) of the system (1 ) would be essentially the same as those described earlier, but with the noticeable exception that according to this particular embodiment, the outlet (1 1 ) of the separating assemblies (7) is "common" to both and is vertically offset with respect to the outlet (15) of each feeding assembly (5). As can also be easily understood by a person skilled in the art, in view of the present description and the accompanying drawings, various other modifications and/or additions could be made to the clip separating system (1 ) without departing from the scope of the present invention. For example, and in order to obtain the same features and advantages which are intended by the present invention, it would be possible to modify the clip separating system (1 ) so as to: a) have cam-shaped movable components (25); b) have two or more different driving paths (10); c) etc.
Moreover, the clip separating system (1 ) may also advantageously comprise a vibration assembly (37) cooperating with clips (3) accumulated within a feeding path (14) of a given feeding assembly (5) for facilitating downward displacement of the clips (3) along the feeding path (14) of said given feeding assembly (5). Various different types of vibration assemblies (37) may be used with the present clip separating system (1 ), but for instance, for the one exemplified in Figures 1 -3 and 9-10, and in the case where the clip separating system (1 ) comprises a pair of feeding assemblies (5), the vibration assembly (37) may simply comprise a pair of vertical flat bars, configured for operatively mounting onto the feeding assemblies (5) by means of corresponding support arms/links, said flat bars being vibrated by a corresponding vibratory cylinder so as to periodically (or cyclically, repeatedly, continuously, etc.) tap against the corresponding clips (3), and thus ensure an improved downward displacement along the feeding assemblies (5). Indeed, it may be appreciated that according to this particular embodiment of a possible vibration assembly (37), the principle lies on the fact of having a pair of blades or bars mounted onto directional coils or lamella ensuring the direction of movement. When oscillating, the flat bars push against the clips (3) and drive the same downwardly towards the separator. Among the various possible resulting advantages, this enables to prevent the clips (3) from undesirably mixing with one and other, ensuring a continuous flow of clips (3) towards the separator and creating a driving force which enables to overcome hesitations and friction forces which could be present. As previously explained, the oscillatory movement of the vibration assembly (37) can be driven by a pneumatic vibrator, or by any other suitable mechanism, such as an electromagnet, a pneumatic cylinder, or any other suitable assembly, as can be easily understood by a person skilled in the art.
According to yet another aspect of the present invention, there is also provided a kit with corresponding components for assembling a clip separating system (1 ) such as the one briefly described herein and such as the one exemplified in the accompanying drawings.
As may now be appreciated, the present invention is a substantial improvement over conventional clip separating systems known in the prior art in that, by virtue of its design and components, as briefly explained herein, the clip separating system (1 ) according to the present invention, enables to overcome several of the aforementioned prior art problems, providing for an easier, more precise, more effective, more reliable and more efficient system.
Namely, the clip separating system (1 ) according to the present invention enables the following advantages with respect to other conventional systems: a) use of a linear and vertical accumulation of clips (3) to ensure proper displacement of the clips (3) along the rail toward the separator, preferably via the effect of gravity; b) entry of the clip (3) into the separator is therefore done directly, thereby eliminating any possible friction due to a re-orientation of the clip (3) via a fixed and curved machined rail; c) a pivot point of the clip (3) to be separated is provided at the inlet (9) of the separating assembly (7); d) reorientation or pivoting of the clip (3) is done in a single step, and preferably along a spring-loaded arc-shaped path (10); e) controlled, fixed and stable geometry of the clip entry (9) of the separator ensures proper and precise entry of the clip (3) into the separator; f) clamping force of the spring-loaded path (10) of the separating assembly (7) is preferably intended to increase as the clip (3) is transferred from the inlet (9) to the outlet (1 1 ) of the separating assembly (7), which namely ensures an improved positioning and securement of the clip (3) at the separator outlet (1 1 ); g) the path (10) or rail of the separating assembly (7) is positioned, shaped and sized to properly maintain the clip (3) via the neck thereof, on each side of the clip (3), thereby preserving the integrity of the clip (3); h) the driving component (19) of the separating assembly (7), with its preferred pushing and supporting sub-components (19a, 19b), is configured for supporting the clip (3) underneath the same while pushing onto the neck portion of the clip (3), thereby further preserving the integrity of the clip (3) throughout the separating process, with the added benefit of acting on the clip (3) via its centre of gravity for even more improved handling and positioning thereof; i) increased repeatability of proper positioning of the clips (3) which enables for smaller tolerances around the clip (3) and thus a tighter and more improved control of clip (3) for an even more efficient clamping thereof, thereby allowing a greater force to be used for inserting the clip (3) into the rubber band (43), thereby increasing the stability of the overall installing process, thereby also enabling to process clips (3) or products that otherwise could not be normally used with conventional systems; etc.
As may also now be better appreciated, the present clip separating system (1 ) is also advantageous in that it enables to overcome different drawbacks and inconveniences associated with conventional systems, namely: a) the clip (3) to be separated is brought to the separator without any substantial risks; b) the clip (3) is brought to the separator via a vertical rail or path (14) enabling the accumulation of clips (3); c) the clip (3) uses gravity as a unique force of positioning in the separator, and thus, a single clip (3) is required for properly locating the clip (3) by itself into the entry (9) of the separator; d) a rotative mechanism (i.e. driving component (19)) pushes the clip (3) through a spring-loaded curved rail (10) to ensure the separation of one single clip (3) at a time, in that if a faulty clip (3) is improperly positioned into the path (10) or has not been picked up by the complementary pick up system, it will be flushed out by a subsequent clip (3) to be separated; e) the rotational operating principle enables an essential reorientation of the clip (3) so as to transfer the accumulated clips (3) in an axis where they can be used directly for the subsequent insertion step; f) the spring- loaded rail or path (10) is designed so as to facilitate the insertion of the clip (3) into the separator; g) the spring-loaded rail or path (10) is designed so as to offer a clamping force which increases progressively along the path (10) of the transfer of the clip (3) so as to ensure a very rapid movement of execution which is optimal (according to tests carried out by the Applicant, about 10 clips/second may be processed); h) the spring- loaded rail or path (10) enables to reduce the impact or adverse effects of imperfections of the plastic clips (3) during the displacement thereof through the different components of the present clip separating system (1 ); i) the spring-loaded rail or path (10) enables a very precise location and positioning of the clip (3) prior to the beginning of the clip insertion; j) if there is a second separation of clip (3) and there is already a clip (3) present in a separator, this latter clip will be automatically ejected by the arrival of a second or subsequent clip (3) because the rail or path (10) is "open-ended" at its distal extremity; k) the system (1 ) enables the provision of two different feeding assemblies (5) or hoppers to one common extraction or pick up point; I) the present system (1 ) does not require the presence of a shifting kit; m) the present system (1 ) increases the global cycle time of the machine when using two different feeding assemblies (5) or hoppers, in that there is no loss of time associated with the use of an auxiliary feeding hopper; n) the present system (1 ) facilitates and increases the adjustment speed of the machine tool at the level of transfer of the clip to the pick up tool to be used for subsequent insertion into the product; o) etc.
Although preferred embodiments of the present invention have been briefly described herein and illustrated in the accompanying drawings, it is to be understood that the invention is not limited to these embodiments and that various changes and modifications could be made without departing form the scope and spirit of the present invention, as defined in the appended claims.
