Abstract
Abstract A bearing is automatically installed on an engine component of a internal combustion engine, such as a connecting rod, a crankshaft, a cylinder block, or the like. Data indicated on the engine component and identifying the engine component is read and stored. A bearing which matches the engine component is selected from a bearing stocker based on the stored data. The selected bearing is then transferred to an installing robot which installs the bearing on the engine component.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
An apparatus for installing a bearing of semicylindrical shape on a variable engine component of an internal combustion engine, comprising: data readout means for determining a specific one of a plurality of different engine bearing by reading data marked on the variable engine component; bearing selecting means for selecting the bearing determined by the data read by said data readout means, and changing the attitude of said bearing: positioning means for receiving the bearing from said bearing selecting means; and bearing installing means for installing the bearing received by said positioning means on the variable engine component; wherein said positioning means comprises a first positioning means for positioning the bearing with its convex side down, and the second positioning means for positioning the bearing with its convex side up; and wherein said bearing installing means comprises a first installing mechanism having a curved surface for engaging an interior peripheral surface of the bearing, and a second installing mechanism comprising means for gripping the engine component.
Claim 2
Independent Claim
165 words
An apparatus for installing a bearing of semicylindrical shape on a variable engine component of an internal combustion engine, comprising: data readout means for determining a specific one of a plurality of different engine bearing by reading data marked on the variable engine component; bearing selecting means for selecting the bearing determined by the data read by said data readout means, and changing the attitude of said bearing: positioning means for receiving the bearing from said bearing selecting means; and bearing installing means for installing the bearing received by said positioning means on the variable engine component; wherein said positioning means comprises a first positioning means for positioning the bearing with its convex side down, and the second positioning means for positioning the bearing with its convex side up; and wherein said bearing installing means comprises a first installing mechanism having a curved surface for engaging an interior peripheral surface of the bearing, and a second installing mechanism comprising means for gripping the engine component.
Claim 3
Dependent Claim
32 words
An apparatus according to claim 1, wherein said data readout means comprises a data readout robot for optically reading the data in the form a bar code marked on the engine component.
Claim 4
Dependent Claim
51 words
An apparatus according to claim 1, wherein said bearing selecting means comprises gripper means for gripping said bearing and attitude changing means for changing to a prescribed attitude the attitude of the bearing received by the positioning means from said bearing selecting means from said gripper means to said positioning means.
Claim 5
Dependent Claim
44 words
An apparatus according to claim 1, wherein said first installing mechanism comprises means for holding said bearing and installing the same on the engine component, and said second installing mechanism comprises means for gripping the engine component and installing the same on the bearing.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 1, wherein each of said data readout means, said bearing selecting means, and said bearing installing means comprises a robot operable in the Cartesian coordinate system.
Claim 7
Independent Claim
170 words
An apparatus for installing a bearing of semicylindrical shape on a variable engine component of an internal combustion engine comprising: data readout means for determining a specific one of a plurality of different engine bearings by reading data marked on the variable engine component; bearing selecting means for receiving said data from said data readout means and for selecting the bearing determined by the data, which bearing corresponds to the desired bearing for the variable engine component; positioning means for receiving the selected bearing; and bearing installing means for installing the bearing received by said positioning means in a predetermined location on the variable engine component; said positioning means including a first positioning means for positioning the bearing with a convex side down and second positioning means for positioning the bearing with a convex side up; said readout means and said bearing selecting means being independently operable for determining and selecting another bearing for another variable engine component while a previously selected bearing is installed by said bearing installing means.
