Abstract

PURPOSE:To align and convey a workpiece smoothly without incling them, by a method wherein an apparatus for conveying irregular-shaped long size members each having irregular portions between their both ends is provided with a pair of roller rails at the right and the left, a roller return device, and a roller supply lift, both ends of each of the workpieces being supported by rollers. CONSTITUTION:Each of irregular-shaped long size members P has both ends 10 supported between a plurality of rollers 9 of a similar diameter which are rotatively fitted in rails 3, the irregular-shaped portions 11, 12 of the member being positioned between the rollers 9, 9 at the right and the left. As a cylinder device 7 operates intermittently, the long size members P advance in rolling method, stop by striking against a stop member 6 and are taken out. The rollers 9 pass through a return passage 5 as shown by white arrows and are locked by a locking piece 8'. A cylinder 8 operating intermittently causes rollers 9 to be transferred onto a lift 4 for conveying the rollers 9 to the starting end of each of the rails 3. The arrangement permits long size members to be smoothly conveyed with their right attitude.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for conveying a long object having different outer diameters along an inclined conveyance path along the longitudinal direction.

[Prior art and problems]

Conventionally, in the case of conveying a long object by rotation on an inclined conveyance path in a manner perpendicular to the conveyance direction, if the long object has a uniform outer diameter, it can be conveyed by rotation without any problem. When transporting long objects with different outer diameters in the longitudinal direction, there was a problem in that the objects were tilted with respect to the transport direction and rotational transport was impossible. [Means for solving the problem] This paper The invention includes a pair of rails arranged at intervals on a base and into which a large number of rollers are fitted, a roller supply lift device arranged facing the starting end of each rail, and It consists of a return path for the rollers from the terminal end to the lower end of the supply lift device, and cylinder devices for intermittent feeding of the rollers in each of the rails and the return path. In order to support both ends of the object, the roller has an outer diameter commensurate with the outer diameter of the object, and both ends of the irregularly shaped elongate object are supported on the roller and conveyed in an aligned state adjacent to each other.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing an outline of the conveyance device. A lift device 4 is provided facing the starting end of the rail 3 and includes a cylinder mechanism for supplying rollers for aligning conveyed objects, which will be described later. A return passage 5, a stopper member 6 provided at the end of each rail 3, and a locking piece 7' provided on the lower surface of each rail 3 and the base 2 for intermittently sending the rollers to the return passage 5.
The cylinder device 8 has a locking piece 8' that intermittently connects the roller to the lifting device 4.

A large number of rollers 9 on which both ends of the long object to be transported are placed are fitted into each rail 3 so that the rollers 9 can roll. Various sizes are available depending on the diameter.

[For production]

FIG. 2(a) shows an example of an irregularly shaped long object P to be conveyed, in which a portion 10 with an outer diameter φ2, an outer diameter φ larger than the portion 10, and a portion 10 with an outer diameter φ2.
2. It consists of a portion 11 and a portion 12 having an outer diameter of φ2□ larger than the portion 11.

As shown in Fig. 2, this long object P consists of a large number of rollers 9 having the same outer diameter and having both end portions 10 fitted into each rail 3.
Each long object P is conveyed in an adjacent aligned state by sequential forward movement of the rollers 9 by the intermittent operation of the cylinder device 7.

FIG. 3(a) shows another example of the irregularly shaped elongated object P, which includes a portion 13 with an outer diameter φ, and a portion 13 with an outer diameter φ1, which is smaller than the portion 13.
It consists of a portion 14.

As shown in FIG. The long object P is conveyed while being supported between a large number of rollers 9□ of large outer diameter fitted into the rollers 91.9□ by sequential forward movement by the intermittent operation of the cylinder device 7 of each roller 91.9□.

At this time, the long object P has a large outer diameter portion 13 and a small outer diameter roller 9.
1, and the small outer diameter portion 14 is supported between the large outer diameter rollers 9□ and transported adjacent to each other, so the long objects P are aligned without being inclined with respect to the transport direction. Transported smoothly and in good condition.

FIG. 4(a) shows still another example of the irregularly shaped elongated object, which consists of a portion 15 with an outer diameter of φ4 and a protrusion 16 eccentric from the portion 15.

As shown in FIG. 4(b), this long object P has one end portion 15 supported between a number of rollers 91 that fit into one rail 3, and the other end portion 15 inside the other rail 3. Each roller 93 is supported between a large number of rollers 94 (same outer diameter as roller 9) that fit into the roller.

The long object P is conveyed by sequential forward rolling due to the intermittent operation of the cylinder device 7 of 94.

At this time, since the long object P has an eccentric protrusion 16, rollers 93 and 94 with an outer diameter that takes into consideration the displacement of this protrusion 16 (shown by dotted lines) are fitted into each rail 3, and the long object P Both end portions 15 of the roller 93. They are supported between 94 and transported adjacent to each other, and are not tilted with respect to the transport direction (
The aligned state is transported smoothly.

As shown in FIG. 1, the irregularly shaped long object P transported as described above comes into contact with the stopper member 6 and is taken out from the transport device I. Further, the intermittent operation of the forward moving cylinder device 7 is performed by an electric signal from a sensor (for example, a photoelectric switch, a proximity switch, etc.) that detects the passage or approach of a preceding roller (not shown). When the locking piece 7' is activated, the locking piece 7' is rotated from the dotted line position to the chain line position in FIG. When the sensor returns, the locking piece 7' is released again.
returns to the dotted line position, and the next roller moves forward and is locked. By repeating such intermittent operations, the long objects P are sequentially conveyed.

Furthermore, the cylinder device 8 is also operated by a sensor that detects the presence or absence of rollers at the starting end of the rail 3, and sends the rollers in the return passage 5 to the lift device 4, which supplies them to the rail 3. The locking piece 8' is pivotally attached at one end and is tightenably attached so that the position of the locking piece 8' can be changed depending on the difference in the outer diameter of the rollers.

〔effect〕

In the present invention, both ends of an irregularly shaped long object are supported by a plurality of rollers corresponding to the outer diameter of the object, and the object is transported by intermittent movement of the rollers, so that there is no inclination with respect to the transport direction.
Smooth conveyance is possible in an adjacent aligned state.
