[Detailed Description of the Invention] The present invention relates to a drive roller type conveyor in which each group of rollers is rotationally driven, and the conveyance performance of conveyed objects is improved.

In conventional drive roller conveyors,
Even if the stop mechanism is released after the flowing object is temporarily stopped by the stop mechanism, the drive roller remains stuck between the object and the object, often causing a conveyance failure. The reason for this is that protrusions, which are cast burrs, attached to the back surface (bottom surface) of the conveyed object cannot overcome the rollers.

Therefore, conventional countermeasures include making the drive roller polygonal or using an eccentric roller with an eccentric roller support shaft. However, polygonal rollers have drawbacks such as damaging the conveyed object (workpiece) and making hitting noises, and eccentric rollers have two-dimensional movement in which both ends of the roller move up and down at the same time, so the ability to convey the conveyed object is limited. No big effect.

In view of the above-mentioned drawbacks of the conventional technology, the present invention provides a protruding spiral protrusion on the outer circumferential surface of the drive roller, and also provides each support shaft on both end surfaces of the drive roller on an inclined axis that is inclined by a certain angle with respect to the roller center axis. It is something that This allows the drive roller to have 180 degrees on both ends.
゜The eccentric rotation movement with a phase shift is performed to give the conveyed object a three-dimensional compound rocking movement in the vertical and horizontal directions, and the spiral protrusion on the outer peripheral surface moves the conveyed object placed on the drive roller. Since it grips the protrusions on the bottom surface and applies propulsion force while making continuous contact with them, it dramatically improves the conveyance ability without damaging the bottom surface of the conveyed object.

On the outer circumferential surface of each of the drive rollers 3..., a right-handed or left-handed threaded spiral protrusion 13 is protruded, and as shown in FIG. 1, several drive rollers 3... with the same thread are arranged alternately. ing. Of course, the arrangement is such that the right-hand screw drive roller, left-hand screw drive roller 3...
The books may be arranged alternately. The support shafts 3 a and 3 b attached to both end surfaces of the drive rollers 3 are placed on an inclined axis O 1 inclined by a certain angle α with respect to the roller center axis O, as shown in FIG.
are provided in accordance with each other. Therefore, the support shafts 3 a and 3 b
The axis position a is a position eccentric from the axis (center axis) O of the drive roller 3 by a radius r. As a result, when the drive roller 3 is rotated, the axis O of the roller 3 makes an eccentric rotation movement between a leftward tilted state O' and a rightward tilted state O as shown by a circular locus f. This eccentric rotation movement causes both the left and right ends of the drive roller 3 to rise and fall in the vertical direction with a phase difference of 180 degrees, while also rotating in the forward and backward direction of the workpiece W in a three-dimensional manner with a phase difference of 180 degrees. to sway.

The protruding stripes 13 can be manufactured by winding and welding a round bar around the outer circumferential surface of the roller, by forming a spiral groove on the outer circumference of the roller and fitting a round bar or hard rubber into it, or by rolling and expanding the groove. Use appropriate means, such as having them appear.

The drive roller type conveyor DC of the present invention is configured as described above, and the chain 9 driven circularly by the drive source rotates each drive roller 3 to the left via the chain 8 of each roller 3. drive in the direction. Now, each drive roller 3... is attached to the support shaft 3.
Using a and 3b as rotation centers, an eccentric rotational movement of a circular locus f is caused. Therefore, as shown in Figs. 2 and 3, the conveyed object W
When there is a protrusion W' of a casting burr on the bottom surface, the spiral protrusion 13 that is in constant contact generates a driving force that continuously pushes the protrusion W' in the conveying direction. This spiral protrusion line 13 is continuously provided on the outer peripheral surface at a certain helix angle regardless of the rotation of the roller 3, so when the work W slips, the protrusion line 13 continues to form the protrusion W'. , and actively pushes the workpiece W in the transport direction at a slower rate than the circumferential speed of the roller 3. Therefore, the stopped workpiece W can be smoothly accelerated to the conveyance speed of the conveyor DC. Further, each of the drive rollers 3 . . . performs an eccentric rotation movement, and swings three-dimensionally in the vertical and front-back directions with a phase difference of 180° at both left and right ends. Therefore, the work W on the conveyor DC is conveyed while being tilted and swung from side to side as shown in FIG. 2, and heavy work W whose bottom surface is not flat can be conveyed even more smoothly.

In addition, in the above embodiment, each drive roller 3...
The left and right ends of ... are synchronously oscillated up and down all at once, but if the individual drive rollers 3 are sequentially shifted by 180 degrees and oscillated up and down, the workpiece W will not be tilted left or right and will not be oscillated. transport. Furthermore, by swinging each drive roller 3 up and down with a slight phase angle shift with respect to the conveyance direction, the work W can be conveyed effectively, much like the crest of a wave on the sea surface moving in the conveyance direction. . In other words, what form of vertical swing motion (3

It is determined according to the processing condition of the bottom surface.

In addition, in the drive roller 3 of the above embodiment, since it is a right-handed or right-handed spiral protrusion 13,
The workpiece W is propelled not only in the conveying direction but also in the axial direction (lateral direction) of the roller 3, resulting in meandering motion. Therefore, as shown in FIG. 4, by protruding spiral protrusions 13' and 13'' of the right and left screws on the left and right sides of the outer peripheral surface of the drive roller 3, the effect of canceling out the lateral propulsive force on the workpiece W can be obtained. be.

By the way, as shown in FIG. 6, there is a straight protruding line 1 on the outer peripheral surface of the drive roller 3 that coincides with the axial direction.
A modification example in which 30 is provided in a protruding manner can be considered. However, similar to the polygonal roller introduced in the preamble, this form scratches the workpiece, generates hammering noise, and does not have the expected conveyance ability.

When using the drive roller type conveyor of the present invention, a spiral protrusion is provided on the outer peripheral surface of each drive roller, and the support shafts provided on both end surfaces of the drive roller are placed on an inclined axis tilted at a certain angle with respect to the roller center axis. Since both ends of the drive roller are eccentrically rotated with a 180° phase shift, the conveyed object is given a compound vertical and horizontal movement, and the spiral protrusions on the outer circumferential surface of the drive roller It captures the protrusions on the bottom of the conveyed object placed on top and applies propulsive force while making continuous contact with it, so it does not damage the bottom of the conveyed object or make any hammering noises.
This has the effect of dramatically improving the conveyance ability, such as smooth conveyance even for conveyed objects that do not have a smooth bottom surface.
