BRIEF SUMMARY
BACKGROUND AND FIELD OF THE INVENTION
This invention relates to an apparatus for conveying articles along a conveying locus or path of a predetermined irregular shape at a constant speed.
In various kinds of article working processes in factories in a variety of technical fields, a great many apparatuses for conveying articles along a circular conveying locus or path at a constant speed have heretofore been employed. However, no apparatus for conveying articles along a conveying locus or path of a predetermined irregular shape has been known.
We have made various close studies to develop an apparatus for conveying articles along a conveying locus of a predetermined irregular shape at a constant speed which is essential for effecting various kinds of article working or production processes continuously and efficiently in a variety of factories and we have succeeded in obtaining a conveyor apparatus according to the present invention which is capable of accomplishing such an object.
Accordingly, the present invention provides an apparatus for conveying articles along a conveying locus or path of a predetermined irregular shape at a constant speed.
The chains which have been employed as one of the means for transmitting motive power in various kinds of machines or production systems have advantageous characteristics for use as constant-speed conveyor units of articles because the locus of movement thereof can be set substantially as desired. Aiming at and making the best use of this characteristic feature of chains, we have devised a conveying apparatus of the present invention which can be moved by a conveyor chain or belt which moves along a conveying locus or path of a predetermined irregular shape wherein means is provided separately for carrying or supporting the articles to be conveyed.
DETAILED DESCRIPTION
The present invention will be described in detail below by way of example only with reference to the accompanying drawings.
In accordance with the present invention, there is provided an apparatus for conveying articles at a constant speed characterized by that it comprises a rotary disk 1 having a plurality of bearings 5 mounted on the outer periphery thereof and a rotary shaft 11 for rotating the disk, a plurality of article support means 3 each having an arm 3b and a connecting member 3c, freely rotatable shafts 4 each adapted to be fitted in one of the bearings 5, said arm 3b being arranged to be slidably fitted into the shaft 4, a conveyor chain 6 arranged to be moved along a conveying locus or path of a predetermined irregular shape regulated or controlled by inner cams 7 and outer cams 8, said conveyor chain 6 being connected with the connecting member 3c, a sprocket 2 adapted to drive said conveyor chain 6 and having a rotating shaft 22, the rotating shaft 11 of the rotary disk 1 being arranged to rotate in synchronism with the rotating shaft 22 of the sprocket 2.
When the constant speed conveyor apparatus of the present invention is rendered operative, the rotation of the rotary disk 1 causes the bearings 5 mounted on the outer periphery thereof to make circular motion while rotation of the shaft 22 of the sprocket 2 in synchronism with that of the shaft 11 causes the conveyor chain 6 to move along a conveying locus of a predetermined irregular configuration under the control of the inner cams 7 and the outer cams 8.
As aforementioned, since the rotating shaft 4 having the arm 3b slidably fitted therein is rotatably fitted in the bearing 5, the article support means 3 will basically be moved by the circular motion of the bearing 5. Because the connecting member 3c is connected with the conveyor chain 6, the article support means 3 will ultimately move along the locus or path of movement of the conveyor chain 6. Thus, if a point in the article to be conveyed on the support means 3 is represented by P, the point P is allowed to move by the circular motion of the bearing 5, and will ultimately be moved by the conveyor chain 6 which moves along a locus of a predetermined irregular shape.
