Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a component receiver in a vibrating component feeder.

[Prior art and its problems] The above method is achieved by forming a spiral track along the inner circumferential wall surface of a bowl-shaped component receiver having an inverted conical shape and applying torsional vibration force to the component receiver. 2. Description of the Related Art Vibratory component feeders that transport components along a track are widely known.

For example, Fig. 14 shows a conventional example of such a component receiver, which is made by deep drawing metal (sheet metal processing).
By doing this, the shape shown in the figure is obtained, and a band (2°) is spirally wound around the inner circumferential wall of the bowl (l) and fixed by welding. This bowl (1°)
The inner circumferential wall surface of is the side wall of the track T1, and the track T1 is formed by this and the strip material (2゛), but the thickness of the part m (disk-shaped part) to be transferred is S They form an equal transport surface, and the diameter of this part m is slightly smaller than the height of the side wall. When a torsional vibration force is applied to such a bowl (1°), this bowl (
1°) A large number of parts are inserted onto the central bottom (1a) m
are transported along tracks 1 to 11, and although not shown in the drawings, usually a part of this truck T is equipped with some kind of parts handling means, and this S, for example, removes overlaps and sorts the front and back sides. The part m is supplied to the next process in a predetermined posture by
Regarding the torsional vibration for o), the circumferential speed of the torsional vibration is different between the center part of the bowl (l'') and the track part located in the radial direction, and therefore the component density is large in the track T1 part on the upstream side of the bowl (lo). However, the density at the downstream end, especially near the discharge end, is small, and there is a limit to the supply speed of parts.

Figure 15 shows another conventional component receiver (3°) (hereinafter also referred to as a bowl), which is also formed by deep drawing of metal, and the inner peripheral wall surface has a spiral shape. A track T2 is formed, which is cut into a step-like shape, and its side wall is along the inner peripheral wall surface of the bowl (3'), and the track T2 is perpendicular to the inner peripheral wall of the bowl (3'). The transfer path (4°) is formed with a width slightly larger than the thickness. Even in the case where part m is transferred by applying torsional vibration to such a bowl (3゛), the transfer speed is small in the central part as in the above conventional example, and in the radially outward direction, that is, near the downstream side of the track. Since the circumferential speed is high, parts tend to become thinner at the discharge end.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and provides a vibrating component supply capable of supplying disc-shaped components, particularly coin-shaped components, to the next process at high speed in a predetermined posture. The purpose is to provide a parts receptacle for machines.

[Means for solving the problem] The above object is to form a spiral cut groove along the inner circumferential wall surface of a bowl-shaped component receiver having an inverted conical shape, and to twist the component receiver. In a component receiver in a vibrating component feeder that transports components along the cut groove by vibration, the cut is formed around a flat or conical center bottom of the component receiver. The cutting groove is formed from the starting point of the cutting groove or near the starting point to a predetermined depth that is at least twice the thickness of the disc-shaped component to be conveyed and a predetermined width that is slightly larger than the diameter of the disc-shaped component. This is achieved by a component receiver in a vibrating component feeder, which is characterized in that it is formed in a vibrating component feeder.

[Function] The center bottom of the parts receiver is flat, like a normal bowl.
Or, it has a short conical shape, but if a large number of disc-shaped parts are put into it and torsional vibration is applied to the parts receiver,
From the starting point of the spiral track formed as a cut groove, or near this starting point, the cut groove has a predetermined depth that is at least twice the thickness of the disc-shaped part to be conveyed, and the disc Since the part is formed with a predetermined width slightly larger than the diameter of the shaped part, a large amount of the part inserted into the center bottom part is in a lying position near the starting point of the ascent of the cut groove, and at least two parts are The disc-shaped parts are regulated by the cut grooves in an overlapping state and transported by torsional vibration. Overlapping parts are transferred downstream in the same way while moving randomly on the cut groove, but the parts in the cut groove on the downstream side are transferred to the above-mentioned upstream side. Depending on the state of transport of the parts, a force is applied to push the parts downstream of these parts in the transport direction, giving so-called back pressure, so that the parts on the downstream side are not only affected by the transport force due to the vibrational force of torsional vibration, but also by the upstream part. Due to the back pressure generated from the transfer force on the parts due to torsional vibration on the side, and the transfer speed of the parts on the downstream side, the circumferential speed is high due to the inverted conical shape of the part being formed on the radially outward side. Therefore, although the transfer speed is originally high, since at least two parts from the upstream side are supplied in an overlapping state, they can be guided to the next process in a predetermined posture in a connected state. Therefore, it is possible to feed this disc-shaped part to the next process in a predetermined attitude at a much higher speed than the conventional component feeder for disc-shaped parts.

[Example] Hereinafter, a vibrating component supply device according to an example of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show the entire vibrating parts feeder (1) to which this embodiment is applied. As shown in Figure 2, the peripheral wall has a spiral track (1
1) is formed. As shown in Figure 1, the bowl (2
) A movable core (3) is fixed to the bottom surface of the movable core (3), which is connected to the lower base block (4) by stacked leaf springs (5) arranged at equal angular intervals. An electromagnet (7) having a coil (6) wound thereon is fixed on the base block (4) facing the movable core (3) with a gap therebetween.

The torsional vibration drive section is constructed as described above, and the entire structure is covered with a cylindrical cover (8).

The entire vibrating parts feeder (1) is supported on the floor by vibration isolating rubber (9).

As shown in Fig. 2, tracks 1 to racks (11) are formed in a spiral shape inside the bowl (2), but the main track (11) is formed along the surface of the bowl (2). It consists of a side wall section (12) which extends vertically from the side wall section (12) and a transfer bed forming section (13) which projects vertically therefrom. Further, according to this embodiment, a component attitude changing means (10) is fixed to the discharge end of the truck (11). As a result, the component m in the lying position is brought into the standing position. Also, an overlap removal device (]4) is located near the discharge end of the truck (11).
is provided, and furthermore, an attitude maintaining means (15) is provided between this and the attitude changing means (10).

Next, referring to FIGS. 3 and 4, the overlap removing device (14
) will be explained in detail. In this device (14), an overlap removal plate (I7) made of urethane rubber and having a planar shape as shown in FIG.
2) is sandwiched between the side wall portion of the
and is fixed to the bowl (2) by a nut (18). Since the overlap removal plate (17) is made of urethane rubber, it is flexible in the direction perpendicular to the side wall (12) as shown in FIG. 12) It maintains a parallel posture to
In this attitude, the distance S between the lower surface and the side wall portion [12] is maintained at a distance greater than the thickness of the component m, but less than twice this thickness. In addition, the overlap removing plate (17) is moved in the transport direction of the component m for a while as shown in FIG.
A taper (17a) that slopes downward toward 3) is formed at the lower edge. This makes it easy for the overlap removal plate (17) to enter downward. In addition, the transfer path forming portion (13) has a Taber notch (13) in the angular range shown in FIG.
a l is formed, which makes the width of the transfer surface (13b) slightly smaller than the thickness of part m, as shown in FIG.

Next, details of the component attitude holding section (15) will be explained with particular reference to FIGS. 2 and 5. As shown in Figure 2, this part extends over an angular range of 45 degrees, but it consists of a wire-shaped earth wall forming member (25) and a component retainer extending in parallel in an arc shape at a predetermined distance from the wire-shaped earth wall forming member (25). A wire-shaped holding member (24) for
It is fixed to the bowl (2) by members (26a) and (26b). The distance between the member (24) and the side wall portion (12) is greater than the thickness of the component m, but less than twice that thickness. Further, as shown in Fig. 5, the part m is moved by vibration while contacting the side wall part (12) in a lying position, and the earth wall member (25) is fixed so as to be close to the upper end thereof. ing.

Next, details of the component attitude changing section (10) will be explained with particular reference to FIGS. 6 to 9.

Part attitude change, the mold part (10) is mainly a transfer path forming plate (2
0), a pair of side wall forming members (231 (29)) and earth wall members (4G) on both sides, which are curved in the direction of transport of the parts as shown in Figures 6 to 9. ,
or its height or width is changed, whereby part m is similarly changed from a lying position as shown in Figures 6 to 9 to a standing position as shown in Figure 7. has been done. In addition, this part posture changing section (
10) Take the entire body (-1 member (30) to remove the bowl (2)
Fixed to .

Further, the upper surface of the transfer path forming plate (20) is used as a transfer surface (21), which is inclined downward as shown in FIG. 8 and has a reduced width as shown in FIG. 9.

In this embodiment, an auxiliary mold curl removal device (72) is further provided upstream of the overlap removal device (14).

This is also constructed in the same manner as the device (14), and a plate (70) made of urethane rubber is fixed to the bowl (2) via a mounting plate (71), and tapers (70a) (70b) are connected to the second
It is formed as shown in the figure.

The vibrating component supply device according to the embodiment of the present invention includes a bowl (2)
Although the structure is as described above except for the details, this operation will be explained next.

Although parts m are shown scattered in FIG. 2, it is assumed that they are actually introduced at a higher density. When alternating current is applied to the coil (6), an alternating attraction force is generated between it and the movable core (3),
This causes the bowl (2) to undergo torsional vibrations in a known manner. Inside the bowl (2), the part m is transferred in a lying position along the track (11). Then, when reaching the auxiliary overlap removal device (72), the parts m that have arrived overlapped have a distance between this removal plate (70) and the side wall part (12) that is larger than the thickness of the part m, but not more than double that. The small structure eliminates overlap. In other words, the overlapping parts fall below the bowl (2), and the lower part enters below the removal plate (7o) made of a single layer of urethane rubber, passes through this and goes downstream. be guided. In the overlap removal device (14), the normally single-layer component m is guided to the downstream side as a single layer.

In the component posture holding section (15), as shown in FIG.
24) to prevent it from falling from the side wall (12) to the lower part of the bowl (2) due to vibrations, and is regulated upward by the member (25), so that there is no single wall on the downstream side. The parts are guided to the part orientation changing unit (lO) in a single layer in rows.

In this changing section (10), as shown in FIGS. 6 and 7, the parts m in the recumbent position are sequentially deflected to take a vertical position, and from this discharge end, one piece is placed in a chamber position. Component m is supplied to the outside at high speed.

The above is a normal operation, but parts m overlap and remover (1
4), or when they arrive in a connected state, the preceding part is removed from the removal plate (1).
4) If the transport speed is reduced due to a collision with the removal plate (17) below, and the speed of the following part is higher, the upper part is moved below this removal plate (17) as before. Suppose that M tends to become occluded due to the wedge effect. However, according to this embodiment, the removal plate (17) is made of urethane rubber and is sufficiently flexible in the vertical direction of the side wall (12), so that it bends in the vertical direction under the force of the wedge effect. As a result, as shown in FIG. 3, the transfer road surface (f13b) of the overlapping part m° is configured to be equal to the thickness of the part m; As shown in FIG.
For 2), it is deflected in the vertical direction and falls downward.

Therefore, only the lower component m is guided downstream.

In addition, in this example, an auxiliary overlap removal device (
72), the load on the downstream device (14) is reduced and the above-mentioned action is reliably performed. The parts attitude holding section (15) maintains the attitude in a single row and single layer and guides the parts to the attitude changing section (10). In this 1, the position is changed from the lying position shown in FIG. 5 to the standing position, and one piece is supplied to the outside in the position shown in FIG. 7.

As described above, part m can be reliably and continuously supplied to the next process in a standing position. There is no blockage like in the past.

The present embodiment is constructed and operated as described above, but although the parts m are only shown scattered in FIG. 2, they are actually introduced at a high density, as shown in FIG. A large number of parts m are put into the. That is,
The case where the parts input density is relatively low has been described above.

Next, the 10th article will be about the bowl processing method according to the present invention.
This will be explained with reference to FIGS. 11 and 12.

The bowl (2) as a component receiver of the present invention has a screw insertion hole (100) formed in the center of a flat plate (2A) made of annealed aluminum plate, for example, as an attachment part to a movable core. As shown in FIG. 11, the flat part (101) serving as the central bottom and the part receiving part and the track part 8 whose depth gradually increases from the cutting start point starting from position P to position Q are N.
It is formed by a C lathe, and the position Q is taken as the starting point of the climb of the main track, from which a cut groove f102) of a predetermined width and a predetermined depth is formed in a spiral shape. As the shape is shown in FIG. 12, the track f102) has the same shape from the climbing start point Q to the discharge end before deep drawing and is in the same plane. 1-Rack (102
) is formed as a vertical wall portion (102a) on the radially inner side and as an oblique wall portion (102b) on the radially outer side, and the space between these is a plane. Further, the height of the vertical wall portion (102a) of this truck (102) is approximately three times the thickness of the disc-shaped component m to be transported. Further, the length of the plane portion between the vertical wall portion (102a) and the diagonal wall portion (102b) is slightly larger than the diameter of the component m. This is formed with the dimensional relationship shown in FIG. As described above, a well-known deep drawing process (sheet metal process) is performed on the 1-rack (102) and the annealed aluminum plate (2A) in which the screw insertion hole (100) is formed in the center. As a result, a poule (2) having a shape as shown in FIG. 1O is obtained. The attachment member (103) for the ring-shaped movable core is welded to the bottom of the bowl (2) to complete the component receiver. No other transport means or attachments are shown. (Due to deep drawing processing, the rack (102) had the same shape and the same attitude in the plane before this processing) - The rack (102) is radially outward (102°) (102°) from the conical center bottom (130).
02") (102°"), the inclination in the bowl radial direction differs toward the downstream side, and
, 30), the track (
As shown by 102-, it is inclined slightly downward in the radial outward direction, and the inclination angle gradually changes upward in the radial outward direction, and on the upstream side, it is inclined as shown in (102''), In a steady state, the wall portion is along the inner circumferential wall surface of the bowl (2) having an inverted conical shape (102'').

Next, a description will be given of the high-speed conveyance of parts of the bowl (2) constructed in this manner. As mentioned above, a torsional vibration force is applied to the bowl (2), and the part m is transported along the track (12), but in this embodiment, the depth of the track (12) is The width is constant and equal to three times the part m, and the width is equal to three times the part m.
The diameter of the part m is only slightly larger than the diameter of the part m to the extent that it does not interfere with the transfer of the part m.
), but in this state they overlap three times or more, and in reality, the three overlapped parts in the track (12) at the starting point of the ascent of the bowl (2) are only partially visible. Component m is transferred by torsional vibration in a state where there is no vibration. Therefore, the rack to 1 as a cut groove (■2)
The three overlapping parts m stuck in the track (12) are regulated by the track (12) and are transferred downstream by torsional vibration, and these parts move the parts with a high circumferential velocity of torsional vibration from the upstream side. It works to push forward, and therefore has a large circumferential speed for the downstream part m,
Therefore, in addition to the original high transfer speed, an even higher transfer speed is obtained by back pressure.Moreover, in this embodiment, the parts m are loaded at a much higher density than in the past, so that the downstream truck ( In step 12), the parts are guided to the sorting section (72) (14) in a high-density, for example, triple or quadruple stacked state, and for the first time in step 5, the parts are arranged in a single layer and formed by the attachment (15). One piece can be continuously fed to the next process at high speed through the part attitude holding path. In FIG. 13, although the posture maintaining track portion is subjected to a torsional vibration force of a large amplitude unlike the conventional one, the articles are discharged from the bowl (2) in a connected state. In addition, although not shown in the above embodiment, as shown in FIG. 13, there is a band-shaped portion (13) forming a transport path for the truck (wall portion (102a in FIG. 12)).
(corresponding to 102b)) by attaching a spring plate (20(1)) that is inclined radially inward with respect to the transport direction of part m, parts that overlap three times or more up to this point will be treated as three times. Therefore, the load on the downstream feeding means can be reduced, and the spring plates can be more reliably fed to the next process in a single row or single layer.Such a spring plate (
200) may be provided not only at the position shown in the figure, but also in a plurality on the upstream side.

In addition, in FIG. 13 (2011 is a hole for removing dust).

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the bowl (2) as a component receiver according to the present invention was obtained by deep drawing an annealed aluminum plate to have the shape shown in the figure.
Instead of this processing method, a casting method called a lost wax method may be used.

Furthermore, in the above embodiments, the shape of the track before deep drawing was such that the radially outward sidewalls faced diagonally, but these were also formed vertically in the same way as the radially inward sidewalls. Good too. Furthermore, it is clear that the material is not limited to aluminum.

In addition, in the above embodiment, the depth of the track portion as the cut groove was three times the thickness of the part m, but it is not limited to this, and if it is twice or more, the effect of the present invention can be ensured. can be obtained.

Further, in the above embodiment, a sorting means for forming a single layer is provided on the downstream side of the track, but a front/back sorting means may be provided instead of or in addition to this.

Alternatively, the materials may be fed to the next step in an overlapping state without using any sorting means.

〔Effect of the invention〕

As described above, the component receiver in the vibrating component feeder of the present invention can feed disc-shaped components in a predetermined state at a much higher speed than conventional ones.
