Abstract

<P>PROBLEM TO BE SOLVED: To provide a part aligning machine usable in a narrow place, by accurately aligning a part with a simple constitution. <P>SOLUTION: A belt conveyor 10 is arranged for transferring the part 2 in the specific direction, and a transfer regulating member 20 having an inclined face 21 slantingly transferring the part 2 in the oblique horizontal direction, is arranged a little above a transfer surface of the belt conveyor 10. While, since this is the part aligning machine for aligning the part 2 transferred in a state of being stored on the belt conveyor 10 in a row state by arranging a freely rocking aligning operation member 40 on the belt conveyor 10, after storing the part on the belt conveyor, the part can be surely aligned by simple operation of only operating the belt conveyor and the aligning operation member. Since the part can be aligned in a row by the aligning operation member and the inclined face of the transfer regulating member, a long belt conveyor is not required, and the part aligning machine can be used in a narrow installation place. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a parts aligner that stores and aligns a large number of parts having an external appearance such as a circular shape or a polygonal shape, and aligns and transfers these parts in a line during transfer by a belt conveyor.

  Generally, when parts are aligned and transferred, a vibratory parts feeder (not shown) is used. This feeder includes a bowl and a main body on which a spiral track is formed, and the components are aligned while being transferred along the track by vibration. However, when parts are aligned and transported by such a parts feeder, the parts that are overlapped during transportation are dropped into the bowl from the track, so that the parts may be chipped or scratched. This causes defective parts.

In order to solve this problem, an aligning and conveying method as shown in JP-A-2-305710 is being adopted. This is as shown in FIG. 7 and FIG. 8, and mainly conveys the chip component 102. The chip component 102 is conveyed by the belt conveyor 110, and the conveying direction is oblique to the belt conveyor 110. The chip component 102 is moved along a guide 120 provided on the belt conveyor 110 and conveyed while aligning the direction of the chip component 102 in a certain direction on the belt conveyor 110.
JP-A-2-305710

  However, in such an apparatus in which guides are alternately provided on the belt conveyor obliquely with respect to the conveyance direction and the parts are aligned in a certain direction and conveyed, a plurality of these guides must be provided alternately. It was necessary to lengthen the entire apparatus. For this reason, it is necessary to make the installation location sufficiently wide, and when used for a processing or assembly line, the entire line becomes large, making it impossible to afford a worker's work space. . Further, since the installation space becomes large, even if it is arranged near the worker, the movement distance of the worker becomes long, so it takes time for the worker to replenish parts. Furthermore, when parts are transported at a predetermined interval, the guide angle with respect to the transport direction of the belt conveyor needs to be finely adjusted every time the parts are changed, or according to the interval. There is a problem that it is necessary to carry out according to the speed of the belt conveyor.

  An object of the present invention is to provide a component aligner that solves such problems and that aligns components accurately with a simple configuration and that can be used in a narrow space.

  An object of the present invention is to arrange a belt conveyor 10 for transferring a part 2 having a predetermined shape in a certain direction, and to incline and transfer the part 2 obliquely and laterally with respect to the transfer direction slightly above the transfer surface of the belt conveyor 10. A transfer regulating member 20 having an inclined surface 21 is provided. On the other hand, an alignment operation member 40 that is swingable along the transfer surface is disposed on the belt conveyor 10, and is stored on the belt conveyor 10 and transferred in a double row state. This is achieved by providing a parts aligner that aligns the parts 2 that have been arranged in a line.

  In addition to this configuration, the transfer surface of the belt conveyor is a flat surface, and a gap is provided between the transfer surface and the transfer regulating member 20 so as not to allow the component 2 to be transferred to enter. Therefore, even if there is dust on the belt, the dust is separated from the conveyor and reliably discharged without being transferred together with the parts. Further, the alignment operation member can be adjusted in its entrance / exit, and the distance between the transfer regulating member 20 and the inclined surface 21 is slightly wider than the width of the component 2 when the alignment operation member 40 is closest to the end. Since it has a configuration with a gap, it can easily cope with the alignment work of all parts.

  According to the present invention, even if the stored parts are transferred in a plurality of rows on the belt conveyor, the parts are inclined and transferred to one side of the belt conveyor by the inclined surface of the transfer restricting member and swing. The parts are unwound by the flexible alignment operation member, and the parts are always aligned and transferred in a line. Thus, after storing the components on the belt conveyor, the components can be reliably aligned by a simple operation of operating the belt conveyor and the alignment operation member. In addition, since the parts can be aligned in a row only by the action of the inclined surfaces of the alignment operation member and the transfer regulating member, it is not necessary to lengthen the belt conveyor as in the conventional case, and it can be used in a narrow installation place. . Further, since it can be used in a small installation place, it can be provided right next to the worker, and the worker does not need to move around. In addition, since there is a gap between the transfer surface of the belt conveyor and the transfer regulating member, the dust on the belt conveyor is reliably separated and discharged without being transferred together with the parts. In addition, since the tip of the alignment operation member can be freely inserted and removed, the distance between the inclined surface of the transfer restriction member can be adjusted according to the part, and it is possible to respond quickly to changes in the part. An effect is obtained.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 2 and 3 are a plan view and a front view showing the whole of the parts aligner, and 1 is a frame. On this gantry 1 is provided a belt conveyor 10 in which a belt 12 constantly circulates and moves in a fixed direction by a rotational drive source 11 to transfer a part 2 having a predetermined shape. The rollers 13 are arranged so as to circulate between them. These rollers 13 and 13 are rotatably supported by frames 14 and 14 on both sides for guiding the belt 12 of the belt conveyor 10. On the other hand, a large number of parts 2 are placed and stored on the belt 12, and the front end portion of the belt conveyor 10 is inclined toward one frame side so that the parts 2 are obliquely transverse to the transfer direction. The inclined surface 21 to be inclined and transferred in the direction is formed toward the upstream side of the belt conveyor 10 and is transferred with a predetermined gap so that the transferred component 2 does not enter between the belt 12 and the transfer surface. The regulating member 20 is fixed.

  As shown in FIG. 1, the end of the inclined surface 21 of the transfer regulating member 20 is adjusted in a direction that crosses the belt conveyor 10, that is, can be moved in and out toward the frame 14, and the distance from the frame 14 is increased or decreased. A width adjusting member 31 is provided. In the discharge gate 30 of the belt conveyor 10 constituted by the width adjusting member 31 and the frame 14, the height interval with the belt 12 is a slide that can move up and down with respect to the belt 12. It is set by the member 32. As shown in FIG. 4, the slide member 32 can be moved up and down by loosening the first setting screw 34 attached to the support guide 33 on the discharge gate 30. It can be fixed by adjusting and tightening.

  On the other hand, as shown in FIG. 2, an alignment operation member 40 whose one end is pivotally supported by the frame 14 is provided at a predetermined cycle on the flat transfer surface of the belt 12 serving as the conveying surface of the belt conveyor 10. The alignment operation member 40 has a regulating operation piece 41 fixed to the tip of the alignment operation member 40 so that it can be adjusted in and out. The restriction operation piece 41 constitutes a part of the alignment operation member 40, and the interval when the movement of the restriction operation piece 41 comes closest to the inclined surface 21 of the transfer restriction member 20 is slightly wider than the width of the component. Is set to As a result, when the component 2 placed and stored on the belt conveyor 10 is changed, the second setting screw 42 is loosened and the restriction operation piece 41 is moved in and out with the component 2 as shown in FIG. This can be easily dealt with by tightening the second setting screw 42 again. The alignment operation member 40 is horizontally oscillated via a connecting rod 44 by an oscillation drive source 43 such as a motor or a cylinder fixed to the frame 14. The swinging of the alignment operation member 40 is set so as to start simultaneously.

  Further, as shown in FIG. 5, the discharge gate 30 is connected to a vibration linearly moving feeder 3 disposed in front of the discharge gate 30, and the parts 2 discharged in an aligned manner are acted on the feeder 3. It will be sent forward. At this time, even if the components 2 are connected, they are solved by the vibration linearly moving feeder 3. Moreover, the feeder 3 has a V-shaped cross section, and a long hole 4 is partly cut out at the bottom of the feeder 3 so that dust (not shown) flowing together with the component 2 is discharged. It has become. A first dust receiver 5 and a second dust receiver 6 for receiving dust discharged from these are provided at the front end of the belt conveyor 10 and below the elongated hole 4 of the feeder 3, respectively.

  In such a component aligner, for example, a predetermined amount of the cylindrical component 2 having a relatively short length is stored on the belt 12 of the belt conveyor 10, and this is put on the belt 12 in advance. The reason for this is to facilitate the alignment, but there is no particular problem even if the component 2 is in the laid state. Then, the distance between the tip of the regulating operation piece 41 of the alignment operation member and the inclined surface 21 is a width that matches the width of the component 2 with the alignment operation member 40 re-approaching the inclined surface 21, that is, one component 2. When the start signal is input after adjusting the interval so that the two parts 2 having the combined width do not pass, but the belt 12 starts to circulate forward at an arbitrary constant speed, the alignment operation member 40 Swings on the belt 12. Thereby, the parts 2 transferred in a double row state are transferred by the belt 12 until they collide with the inclined surface 21 of the transfer regulating member 20, but when the parts 2 collide with the inclined surface 21, the transfer is blocked, The component 2 moves along the inclined surface 21 in an oblique lateral direction toward the frame 14 on the downstream end side of the inclined surface 21.

  At this time, since the alignment operation member 40 is oscillating at a constant cycle, the movement of the parts 2 placed on the belt 12 is blocked by the inclined surface 21 and the alignment operation member 40 and becomes a lump. However, the lump of the component 2 is unwound by this swinging operation, and the component 2 is aligned in a line along the inclined surface 12 and moves toward the discharge gate 30. On the other hand, the part 2 that has reached the discharge gate 30 is adjusted in advance by the width adjusting member 31 and the slide member 32 so that one part 2 passes through one part. Even if it enters in a row, the overlap is released at this position, and the part 2 is discharged from the discharge gate 30 to the one-way vibration linear feeder 3.

  As described above, in this embodiment, the component 2 is transported in a state where it is erected on the belt 12 in advance. However, the present invention is not limited to this, and the size of the component 2 is not limited thereto. Alternatively, there is no need to stand depending on the shape. If such a component aligning machine is installed behind the automatic processing machine for the part 2 and a counting device is installed downstream of the feeder 3, it is possible to automate consistently from machining to counting of parts. .
