JPS624157A - Aligning device for plate-like material - Google Patents

Abstract

PURPOSE:To make it possible to use an aligning device even if the lengths of plate-like materials differ, by rotating upward digit-like scoop arms disposed between rollers in a roller conveyer, to align the plate-like materials on the conveyer along their one end edge. CONSTITUTION:Digit-like scoop arms 16 are provided between rollers, being loosely fitted on a shaft 14 by means of torsion springs 22 incorporated in boss sections 20, and may be rotated by air cylinders 17. A rod 30 is slidably disposed in each boss section 20 facing each scoop arm 16, and when the rod 30 is projected from the scoop arm 16 positioned at the lowermost position 18, the scoop arm 16 is not rotated but the spring 22 along is rotated. When the entrance of a material 5 is detected in a condition in which the rod 30 is retracted, the scoop arm 16 is rotated upward in association with the operation of a cylinder 17 to scoop up the material 15 to allow the latter to slide down to the edge 33 of the arm to regulate the lower end position of the material 15. With this arrangement, required arms 16 along are rotated in accordance with the length of the material 15 so that the positions of various materials 15 may be regulated to align the material 15 which are fed at random.

転を行うこととなる。(Means for Solving the Problems) FIG. 1 shows a conveyor with an alignment device according to the present invention. Fig. 6 is a cross-sectional view of Fig. 1 9-10, Fig. 4 is a rake arm, Fig. 5 is a partially cutaway perspective view of the rake arm attachment part, Fig. 6 is a 11-12vc in Fig. 5. FIG. As shown in FIG. 1, a conventional drive roller conveyor is provided with a bearing 13 and a shaft 14 supported by the bearing, and the shaft 14 has several comb-shaped scoop arms 16 supported by an arm 15 and a boss portion 20. was installed between the rollers, and an air cylinder 17 was attached to the arm 15 as shown in FIG. 5 so that the scooping arm 16 could be rotated between the lowest position 18 and the highest position 19. The rake arm 16 has a stopper edge 33 perpendicular to its upper edge as shown in FIG. 4, and as shown in FIG. The rake arm 16 is attached to the boss portion 2 as shown in FIG.
A torsion spring 22 is built into the shaft 14, and the shaft 14 is loosely engaged with the shaft 14. The torsion spring 22 is fixed to the boss 20 at one end and to the ring 25 at the other end. Also, ring 2°5 is spring 2

The rod 30 can be stopped at a predetermined position by, for example, a combination of recesses 51, 52 and a ball plunger (not shown). That is, the rod 50
If the scooping arm 16 is made to protrude above 16 when it is at the lowest position 18, even if the shaft 14 is rotated, the scooping arm 16 will not move.
The rod 30 prevents rotation and does not rotate, and only the internal spring 22 rotates (however, within the range of the notch 25). That is, the rake arm 16 rotates together with the shaft when the rod 50 is pulled to the left due to the fifth factor, and rotates together with the shaft when the rod 60 is positioned to the right (with the rake arm 16 at the lowest position). will rotate only.

7 holds the scooping arm 16 at the lowest position 18, and at the same time detects that the material 5 is completely placed above all the scooping arms 16 (for example, detects the leading position of the material 5). When the cylinder 17 is activated and the scooping arm 16t is instantaneously rotated to the highest position 19, the material 5 on the roller 1 is scooped up by the arm 16 and slides down to the edge 56, its lower end position being regulated. At the same time, when the arm 16 is instantaneously rotated again by the cylinder 17 to the lowest position 18, the material 5 remains on the roller and continues to be conveyed to the next work step 6.
