As an edge part, the other side edge is formed into a slanted track which is a low edge part having a bank, and a straightening claw that can freely move in and out of the bank is provided,
A detection zone with a sensor having a predetermined width set from the high edge portion to the low edge portion is provided on the track surface in the vicinity of the front of the straightening claw, and the ellipse object passing through the detection zone is detected by the sensor. The corrective claw is configured to project onto the transport track upon detection of the transporting posture, and the projecting corrective claw straightens and converts the illegal transporting posture into the normal transporting posture.

"Operation" With the above arrangement, the alignment progressive mechanism of the present invention detects elliptical objects in a horizontal position and an oblique position that have been conveyed on a slanted track in the detection zone. Since it interferes with the corrective nail protruding to, and a rotational moment about the contact point of the corrective nail that comes into contact with the center of rotation is applied, it is corrected to the vertical position while being offset to the lower edge of the inclined track, and is conveyed. All of the above ellipses are arranged in a vertical position and sent in order.

"Example" Hereinafter, it demonstrates in detail based on an Example. First, referring to FIG. 1 showing the first embodiment, in the confectionery manufacturing process, a work 1 of a plate-like ellipsoid is sequentially conveyed on a conveyance track 2 of a vibration feeder, and its conveyance posture is shown. An aligning and feeding mechanism is shown which arranges in the lengthwise direction and feeds it to the next step. More specifically, the transport track 2 is formed on a slanted track 7 whose one side edge in the transport direction is a high edge portion 3 and the other side edge is a low edge portion 4, and the work 1 is prevented from falling off on the low edge portion 4. And a bank 5 serving as a conveyance guide are erected integrally.

A straightening claw 6 that moves in and out of the side bank 5 is provided at an arbitrary position on the side bank 5, and a sloped track near the front side of the straightening claw 6 (the side to which the workpiece 1 is sent is called the front side). A detection zone 8 having a width B preselected in the direction from the high edge 3 to the low edge 4 is set on the surface of 7.
A sensor 9 having the detection zone 8 as an effective detection area is provided above the detection zone 8. Then, a part of the work 1 ′ having a horizontally long posture, which is not the normal longitudinal conveyance of the normal conveyance posture, and an illegal conveyance posture, which is an oblique posture, always passes through the detection zone 8 and passes through the detection zone 8 by the sensor 9. By the detection of the work 1'in the illegal conveyance posture, the straightening claw 6 is projected to the transporting track 2 and the detected portion of the work 1'close to the lower edge portion 4 comes into contact with the straightening claw 6 for contact. Has become.

That is, the correction nail 6 is provided for the purpose of correcting the posture by giving a rotation moment to the work 1'by contact with the work 1'in the bad posture detected by the sensor 9, and the specific shape of the work 1 ' Considering the size, the conveying force of the work 1 by the conveyance track 2, the friction between the work 1 and the inclined track 7, and the like, the protruding timing at which the above-mentioned rotational moment effectively occurs, the protruding length L, and the protruding retention The time is experimentally determined, and the operating condition of the correction nail 6 is selectively set for each characteristic of the work 1. In addition, in the figure
Reference numeral 10 is an operating portion of the correction nail 6, and an operating portion of a known means such as an air cylinder or an electromagnetic structure is used.

According to the alignment progressive mechanism of the embodiment of FIG. 1 described above, FIG.
As shown in (B), the workpieces that are sequentially fed on the inclined track 7 are conveyed to the lower edge portion 4 by gravity due to gravity work, both the vertically long workpiece 1 and the horizontally or diagonally inclined workpiece 1 '. The workpiece 1 in the vertically long posture advances without passing through the detection zone 8. And the detection zone 8
When the work 1'containing a part of the contact portion comes into contact with the protruding corrective nail 6, the advancing force of the contact portion is suppressed by the corrective nail 6 and the portion not in contact with the corrective nail 6 receives the conveying force of the conveying track 2. Therefore, a rotation moment M about the contact point with the straightening claw 6 as the center of rotation is generated in the work 1 ′, the tip is rotated, and the work 1 ′ is straightened to be tilted along the edge bank 5 and is tilted on the inclined track 7. Sorted and ordered.

Next, FIG. 2 shows a second embodiment of the arrangement-and-forwarding mechanism for the plate-shaped rectangular objects in the confectionery manufacturing process. That is, in the progressive alignment mechanism having the same inclined track 7, corrective nail 6, detection zone 8 and sensor 9 as in the embodiment of FIG.
With straightening pawls 6 are a plurality of primary straightening pawls 6A and secondary straightening pawls 6B were arranged at intervals L _3, the protruding length of the "secondary straightening pawls 6B L _2> protruding length of the primary straightening pawls 6A L The relationship is ₁ ". In this embodiment shown in FIG. 2, the pattern of the work 1'entering the sensing zone 8 is sensed by the sensor 9 and the detection pattern is in a rearward oblique posture (a posture in which the high edge portion 3 side is left). At this time, a large rotational moment is required to convert the work 1 ″ into the vertically long posture. Therefore, the two correction nails 6A6B are simultaneously released, and the primary rotation moment M ₁ and the secondary correction nail 6B generated by the primary correction nail 6A.
The second rotational moment M ₂ is continuously given to enable accurate posture conversion as shown in the figure. When the secondary correction nail 6B is unnecessary according to the detection pattern, the posture is corrected only by the primary correction nail 6A as in the embodiment of FIG. 1, and the correction nail 6B is projected based on the type of the detection pattern. The timing, the protrusion length, and the protrusion holding time are controlled so that the workpieces in all the postures that enter the detection zone 8 are accurately converted into the vertical posture and corrected.

According to the above embodiment, in the middle of the transport truck,
The posture of the work in the defective conveyance posture is accurately changed, and the work can be arranged in the vertical posture and sequentially fed without causing a defective phenomenon such as damming. Further, even when the work is converted into a company, it is only necessary to adjust the operating condition of the correction nail 6 and the detection zone 8, which is simpler and faster than the setup work of the conventional means.

Although not shown, as another embodiment, the detection zone 8 does not necessarily have to be provided with the width B, as shown in FIG.
If there is a detection inner line 8'shown in, it works.
It may be linear along the inner line 8 '.
