Description

  The present invention removes as much as possible dust, such as chips and scraps mixed in a component supply machine, in a component supply machine that aligns and supplies components supplied from a belt conveyor or a feeder. The present invention also relates to a dust recovery device that recovers the dust.

  In general, when aligning and supplying parts, a vibratory parts feeder (not shown) is used. This feeder is provided with a bowl and a main body in which a spiral track is formed, and is arranged such that parts are supplied along the track by vibration. However, when aligning and supplying parts with such a parts feeder, the dust mixed in the parts is often thrown in together, so the dust is also mixed and fed while supplying the parts. If dust is mixed, this may cause damage to the parts and cause defective parts.

In order to solve this problem, it is necessary to separate parts and waste as much as possible. For this reason, an aligning and conveying method as shown in JP-A-2-305710 is being adopted. This is as shown in FIG. 6 and FIG. 7, 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. A metal part is conveyed by adopting a conveyance method of conveying such parts while meandering.
JP-A-2-305710

  However, in such an apparatus in which guides are alternately provided on the belt conveyor obliquely with respect to the conveying direction and the parts are aligned in a certain direction and conveyed while meandering, the parts and dust are conveyed while being unwound. However, a plurality of guides must be provided alternately, the belt conveyor becomes relatively long, and the entire apparatus needs to be lengthened. For this reason, it was necessary to make the installation place sufficiently wide. Moreover, although some dust is unraveled from the parts during the conveyance, it is still conveyed along with the parts, so it was necessary to provide a special device for removing the dust. Further, when such an apparatus is provided, the structure becomes complicated and the cost becomes high, and the spread of the apparatus in an automated conveyance machine is hindered. Furthermore, when the parts have a certain weight, a method of blowing off the dust with air or the like can be considered, but if the dust is blown off in this way, the dust will be scattered and it will be difficult to recover the dust. Has occurred.

  An object of the present invention is to provide a component feeder that solves such problems and has a simple configuration, reliably separates components and dust during component supply, and can quickly collect dust. It is to obtain a dust recovery device.

  An object of the present invention is to dispose a belt conveyor 10 that supplies a predetermined shape of the component 2 in a certain direction, and to provide a gap between the belt conveyor 10 and the belt conveyor 10 above the component supply end side. In the component supply machine, the supply direction changing member 20 for guiding the component 2 to the discharge gate 30 is provided and the component 2 is supplied onto the supply path 51 connected to the discharge gate 30. A first dust collection case 53 for receiving dust 3 falling from above the belt conveyor 10 is disposed below the component supply end of the belt conveyor 10 by a length equal to the width of the belt conveyor 10, while the discharge gate 30 A dust discharge groove 52 that is long and narrow along the supply direction is formed in the bottom surface of the connected supply path 51, and a second dust collection case 54 is disposed below the dust discharge groove 52. The dust 3 on the belt conveyor 10 excluding the parts 2 to be supplied with the supply direction changed by the supply direction changing member 20 is the first dust recovery case 53, and the dust 3 on the supply path 51 is the second dust recovery case 54. This is achieved by providing a dust recovery device that drops and recovers each.

  According to the present invention, even if dust is mixed into the stored parts and the dust and the parts are supplied on the belt conveyor, the parts are placed on one side of the belt conveyor by the inclined surface of the supply direction changing member. The parts and dust are separated by separating the parts and the dust adhering to them by the swingable alignment operation member that is supplied obliquely toward a certain discharge gate, and the parts are always aligned and supplied in a line. The On the other hand, since the dust separated from the parts is supplied on the belt conveyor in the direction of supply of the belt conveyor, the dust falls downward from the supply end of the belt conveyor, and the dust is stored in the first dust recovery case. And is reliably recovered. In addition, since the parts can be aligned in a line only by the action of the inclined surfaces of the alignment operation member and the supply direction changing member, the parts can be accurately supplied to the discharge gate. Furthermore, since this device does not require any special dust removing device, the overall structure of the device is simple, the cost required for it is reduced, and the spread to automatic equipment is promoted. In addition, even if the dust is not completely removed from the parts that are aligned and supplied on the supply path, the dust is dropped and discharged from the dust discharge groove of the supply path while passing through the supply path, and the second dust just below it is discharged. Since it comes into the collection case, it is almost eliminated that the dust is finally supplied together with the parts. In addition, the dust is not blown away by air, and a specific effect such as no dust scattering 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 aligning and supplying machine, and 1 is a frame. On this gantry 1, a belt conveyor 10 is provided that constantly circulates and moves an endless belt 12 in a fixed direction by a rotational drive source 11 and supplies a part 2 having a predetermined shape. It is designed to circulate between rollers 13 disposed at the rear end. These rollers 13 and 13 are rotatably supported by frames 14 and 14 on both sides for guiding the endless belt 12 of the belt conveyor 10. On the other hand, a large number of parts 2 are placed and stored on the endless belt 12 and inclined to one frame side above the part supply end side located at the front end of the belt conveyor 10. An inclined surface 21 that supplies the component 2 obliquely in the lateral direction with respect to the supply direction is formed toward the upstream side of the belt conveyor 10, and the supplied component 2 is provided between the conveying surface of the endless belt 12. A supply direction changing member 20 having a predetermined gap that does not enter is provided.

  As shown in FIG. 1, at the end of the inclined surface 21 of the supply direction changing member 20, the direction crossing the belt conveyor 10, that is, the space between the frame 14 and the frame 14 can be adjusted so that it can be projected and retracted. A possible 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 between the endless belt 12 and the endless belt 12 is vertical. It is set by a movable slide member 32. As shown in FIG. 4, the slide member 32 can be moved up and down by loosening the setting screw 34 attached to the support guide 33 on the discharge gate 30 and adjusted to a position corresponding to the height of the component 2. It can be fixed by tightening it.

  On the other hand, as shown in FIG. 2, on the flat conveying surface of the endless belt 12 of the belt conveyor 10, an alignment operation member 40 whose one end is pivotally supported by the frame 14 is horizontally oscillated at a predetermined cycle. The alignment operation member 40 has a tip that can be adjusted in and out. The tip of the alignment operation member 40 is set so that the interval when the tip of the alignment operation member 40 swings and is closest to the inclined surface 21 of the supply direction changing member 20 is slightly wider than the width of the component. Further, the set amount can be easily adjusted even if the component 2 placed and stored on the belt conveyor 10 is changed, and the alignment operation member 40 is a motor fixed to the frame 14, Alternatively, the rocking drive source 41 such as a cylinder is horizontally swung through the connecting rod 42, and the rocking of the alignment operation member 40 is set so as to start simultaneously with the circulating movement of the endless belt 12. Yes.

  Further, as shown in FIG. 4, the discharge gate 30 is connected to a supply path 51 of a vibration linearly moving feeder 50 arranged in front of the discharge gate 30, and the components 2 aligned and discharged are arranged in a row. It is acted on and is sent forward. At this time, even if the components 2 are connected, they are solved by the vibration linearly moving feeder 50. Moreover, the supply path 51 of the feeder 50 has a V-shaped cross section, and a dust discharge groove 52 that is long and narrow in the supply direction is formed on the bottom surface of the supply path 51 as shown in FIG. The dust 3 that has been cut out and flows together with the component 2 is discharged. Note that the parts supply end located at the front end of the belt conveyor 10 and the dust discharge groove 52 of the feeder 50 have a length equal to the width of the belt conveyor 10 so as to receive the dust 3 dropped and discharged therefrom. A second dust collection case 54 having a length equal to or longer than the length of the first dust collection case 53 and the dust discharge groove 52 is provided.

  In such a component aligning and supplying machine, for example, a predetermined amount of the cylindrical component 2 having a relatively short length is stored on the endless belt 12 of the belt conveyor 10, and this is set on the endless 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 space between the tip of the alignment operation member 40 and the inclined surface 21 is adjusted to the width of the component 2 with the alignment operation member 40 re-approaching the inclined surface 21 in advance, that is, one component 2 passes. However, since the parts 2 having the width of the two pieces are adjusted so as not to pass, when the start signal is input, the endless belt 12 starts to circulate forward at a constant speed as shown in FIG. The alignment operation member 40 swings on the endless belt 12. As a result, the component 2 supplied in a double row state is supplied by the endless belt 12 until it collides with the inclined surface 21 of the supply direction changing member 20, but when the component 2 collides with the inclined surface 21, The supply is blocked, and the component 2 moves obliquely in the lateral direction along the inclined surface 21 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 period, the inclined surface 21 and the alignment operation member 40 prevent movement of many parts 2 while being placed on the endless belt 12. However, the mass of the part 2 is unwound by this swinging motion. The dust 3 mixed with the component 2 on the endless belt 12 passes through the gap between the supply direction changing member and the conveying surface of the endless belt 12, and is further forwarded. It falls into the first dust collection case 53. On the other hand, the components 2 are aligned in a line along the inclined surface 12 and move toward the discharge gate 30, and the component 2 that reaches the discharge gate 30 vibrates to one from the discharge gate 30 as shown in FIG. 4. It is discharged onto the supply path 51 of the straight feeder 50.

  As shown in FIG. 5, the component 2 discharged onto the supply path 51 in this way is further supplied forward on the supply path 51, and a small amount of dust 3 supplied from the endless conveyor 12 together with the component 2. Even if it is sent onto the supply path 51, it falls from the dust discharge groove 52 of the supply path 51 and is recovered in the second dust recovery case 54. The dust 3 collected in the first and second dust collection cases 53 and 54 below the part supply end of the endless belt 12 and the dust discharge groove 52 of the supply path 51 of the vibration linear advance feeder 50 is surely prevented from scattering. It will be recovered and removed.

  As already described, in this embodiment, the component 2 is supplied in a state where it is erected on the endless belt 12 in advance. However, the present invention is not limited to this. There is no need to stand depending on the size or shape. Further, instead of the vibration linearly moving feeder 50, an inclined feeder or the like may be used.

It is a principal part enlarged plan view which shows this invention. It is a top view which shows the outline | summary of this invention. FIG. 3 is a front view of FIG. 2. It is a partial enlarged front view showing the 1st dust collection case concerning the present invention.
