Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG. 1 illustrates the flow of operations within one embodiment of the present invention.

[0013] FIG. 2 depicts one embodiment of the present invention in which lubrication is provided through a 10- and a 12-point lube control device (secondary control device).

DETAILED DESCRIPTION OF THE INVENTION

[0014] This description, with reference to the figures, presents non-limiting examples of embodiments of the present invention.

[0015] As depicted in FIG. 1, in one embodiment of the present invention, the automated lubrication system 100 features a system control panel 130 operably coupled to both a master control device 120 and an air supply unit 150 via signals 126 and 128 respectively. The master control device 120 and air supply unit 150 are coupled to a lubricant pump 160 to effectuate delivery of an amount of lubricant to at least one lubrication point of a plurality of lubrication points. Said system control panel 130 is configured to cause said amount of lubricant to be delivered at a predetermined time interval.

[0016] When a user wants to begin the lubrication process, the system control panel 130 is activated by an On/Off switch 140. When activated, the system control panel 130 causes a signal 128 to be transmitted to the air supply unit 150 via a solenoid which in turn causes air to flow into the lubricant pump 160. The lubricant pump 160 is coupled to the master control device 120 with a supply line 158 through which lubricant is transferred when air is flowing from the air supply unit 150.

[0017] Still referring to FIG. 1, system control panel 130 can be any similar multipurpose programmable controller. In this embodiment, master control device 120 is shown as a reversing valve acting essentially as a pump-stroke counter to assist in regulating lubricant transfer. Secondary control device 110 is depicted as a hydraulic valve capable of discharge quantity adjustment.

[0018] The master control device 120 is further coupled to at least one secondary control device 110. The secondary control device 110 is coupled to said at least one lubrication point of said plurality of lubrication points via a lubricant line 108. The master control device 120 and at least one secondary control device 110 are configured to deliver said amount of lubricant to said at least one lubrication point. Said master control device 120 and said secondary control device 110 may also be configured to deliver said amount of lubricant to each lubrication point of said plurality of lubrication points.

[0019] The master control device 120 may also include a relief outlet 118 through which lubricant in excess of said amount may be returned to the lubricant pump's 160 reservoir.

[0020] Additionally, the system control panel 130 may be low voltage requiring and be programmed with software that monitors and regulates the timing of lubricant delivery by causing the air supply unit 150 to begin or terminate air flow to the lubricant pump 160. In this manner, air flow may be limited to only that which is needed to effectuate the desired lubrication.

[0021] In other embodiments, the lubricant pump 160 utilizes a bucket container to store the lubricant.

[0022] In certain embodiments, the lubrication points are valve seats and the lubricant is grease. Grease is applied evenly on said valve seats to ensure better grease coverage.

[0023] In another embodiment, the plurality of lubrication points corresponds to an 11 dual/valve system wherein each lubrication point is a main plug valve. When activated, the system control panel 130 causes each main plug to be lubricated in 3 minutes.

[0024] In some embodiments, the system may be partially contained and secured in a locked metal cabinet to minimize risk of contamination or harm to personnel in the vicinity of the air supply unit 150 and lubricant pump 160.

[0025] FIG. 2 depicts one embodiment of the automated lubrication system 200 in which lubrication is provided through a 10- and 12-point lubrication control device (210 and 212 respectively, each a secondary controlled device). The automated lubrication system 200 features a system control panel 230 coupled to a lubrication pump 260 to effectuate delivery of an amount of lubricant to at least one lubrication point of a plurality of lubrication points via a master control device 220. Pump 260 can be a 70:1 pump (5 gallons).

[0026] Although particular detailed embodiments of the system and method have been described herein, it should be understood that the invention is not restricted to the details of the preferred embodiment. Many changes in design, composition, and configuration are possible without departing from the spirit and scope of the instant invention.
