Abstract

PROBLEM TO BE SOLVED: To make it possible for parts to be transferred without being turned over in the course of transfer even when the amplitude of vibration is increased to make the amount of movement greater when slender tabular parts are transported by means of a torsionally vibrating part-feeder. SOLUTION: In order to transfer parts M in bowl 21 of a torsionally vibrating partfeeder 100, circular trough-tracks 44, 64, 84, 114 are laid around a peripheral wall 23 in a circular manner. Thus, the parts M make four-point contact with each other to be stably transferred. Further, the rearrangement of the parts M where a high accuracy screening is required, into a single-layer, a single row, and the stabilization of the surfaces and the backs of the parts M, are performed on a straignt plane track where the parts M come into face contact with each other in order for the size of the parts to be easily determined.

A conventional parts feeding device 2
0 has the above-mentioned structure and functions, but has the following drawbacks. That is, the conventional parts feeding device 20
Has the ability to feed 40 parts M per minute, but in order to improve this to 80 parts per minute, for example, the amplitude of torsional vibration is 0.4 mm to 0.6 m.
When the value is increased to m, there is a case where some of the sheets are turned upside down during the transfer. Even though the front and back straightening block 352 has been arranged in the front direction, a sorting block 382 is generated by causing the boat bottom track 368 and the slope track 374 to be reversed.
More will be eliminated in the sorting block 382.
However, the target improvement in the feeding capability could not be achieved, such as the occurrence of some reversal in the downstream sloped track 394 despite the removal of the downward facing part M.

Therefore, according to the present invention, even if the amplitude of the torsional vibration is increased to increase the transfer amount of the slender plate-shaped parts, the parts are not inverted in the truck during the transfer, and the parts feeding apparatus having the improved transfer capability is provided. The challenge is to provide.

[0030]

[Means for Solving the Problems] The above-mentioned problems are solved by twisting and vibrating a bowl having a spiral track formed therein so that a long and slender plate-shaped component is formed into a single layer or a single layer with its longitudinal direction oriented in the transfer direction. In the parts feeding device for feeding to the next process in a row, the uppermost step portion of the track has an arcuate track portion having a semicircular or U-shaped cross section, and an upstream end portion of the arcuate track portion. Or a linear track portion having a V-shaped cross section continuously connected to the upstream end portion and the downstream end portion of the arcuate track portion, and the linear track portion is connected to the downstream end portion. A V-shaped groove having a V-shaped cross section with a gradually increasing depth is formed in the downstream side portion of the arcuate track portion, and the inclined surface on the radially outer side of the V groove is formed outside the diameter of the linear track portion. A part feeding device characterized by being aligned with a slope on one side, Thus it is achieved. In this structure, in the arcuate track portion, the elongated plate-shaped component is transferred on this transfer surface with four-point support. Therefore, compared with the conventional three-point support, it is transferred more stably, that is, it is transferred by torsional vibration without inverting the front and back, and is also used for single row, single layer, front and back sorting, and front and back correction of parts. You can surely guide to the straight track part in its original posture,
After being subjected to a predetermined alignment action, it may be guided to the next arcuate track portion having a similar cross-sectional shape, and in the straight track portion, it may be subjected to another or similar alignment action and guided to the downstream side. . Therefore, no matter what sort of alignment action is performed, after that, the alignment state is not disturbed and the supply is continued to the next step, so that the supply efficiency can be improved as compared with the conventional case.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a plan view of the parts feeding device 10 of the present invention, which is the main component of the torsional vibration parts feeder 100.

At that time, the part M is transferred to the round gutter track 44 at the four corners of the bottom surface. Contact four points. Instead of the round gutter track 44, a track having a semi-elliptical cross section may be used. Further, those radii of curvature are set mainly according to the width of the parts to be fed. Further, the radius of curvature of the circular gutter track 44 laid in an arc shape when viewed in the plan view of FIG. 2 is set mainly according to the length of the parts to be fed. Any radius of curvature is appropriately determined according to the size of the component to be fed, and is not generally specified. These values are set so that the parts are transferred in four-point contact with a track laid in an arc shape. The same applies to the other round gutter tracks 64, 84, 114.

FIG. 8 is a perspective view of the vicinity of the linear short first alignment block 52 in which the L track 54 is formed.
The L track 54 of the first alignment block 52 has a slope 54
a and 54b, and upstream and downstream thereof are a round gutter track 44 and a round gutter track 64, respectively. Second
The alignment block 72 is almost the same, and the V track 94 of the front / back correction block 92 shown in FIG.
4b, with a round gutter truck 84 upstream and downstream.
And a round gutter truck 114.

In this way, the parts M are made into a single layer, a single row, and the front and back are made uniform by the block based on the linear short flat track, so that highly accurate selection is performed. Before and after the parts M, the parts M are stably transferred without being turned upside down.

The component feeding apparatus 10 according to the embodiment of the present invention is configured as described above, and its operation will be described below.

In FIG. 2, the part M accommodated in the bottom surface 22 of the bowl 21 is subjected to torsional vibration, moved to the peripheral portion and transferred in the direction indicated by the arrow m, and rides on the flat plate track 24 from the starting point 24s. If the parts M are excessive while being transported on the flat plate track 24, they fall from the notches 25 and are quantified. The component M is lifted up on the flat plate track 24 to the uppermost circumference, and
The round gutter truck 44 of the truck block 42 laid outside the bowl 21 is transferred via the lead-out block 32 shown in FIG. The component M is transferred on the center line of the round groove track 44, that is, on the outer peripheral side of the bottom of the round groove track 44 by the component of the transfer force of the torsional vibration that is directed outward in the radial direction of the bowl 21. At this point in time, the parts M are in multiple layers and multiple rows while the front and back are indefinite, and the parts M that have been crowded by the air blown out from the air jet nozzle 39 shown in FIGS. 4 and 6 are separated to facilitate the transfer.

To the downstream end of the round gutter track 44, the component M is mainly transferred to the slope 45b of the V groove 45 by being inclined and transferred through the shallow groove 46 which can enter in a single row and the first alignment block 52.
Sent to the L-shaped track 54 of the
It is transferred while tilting to 4b. As shown in FIG. 9, the slope 54
Although the width of a is slightly wider at the upstream end, it is set to a width corresponding to the thickness of two pieces of the component M shown by the broken line from immediately downstream, so that the components M stacked in three or more layers have slopes 54a. It cannot be supported and falls onto the block support plate 31 and is eliminated. That is, by passing through the first alignment block 52, the components M are roughly aligned in a single row or a double row with a maximum of two layers overlapping. The component M dropped on the block support plate 31 is guided by the guide plate 37 ₁ shown in FIG. 11 and returned to the uppermost orbit of the flat plate track 24 in the bowl 21.

Part M that has passed through the first alignment block 52
Is transferred to the round gutter truck 64 of the following truck block 62. During this transition, the air ejection nozzle 59 shown in FIG.
The air blown out of the device separates any congested parts M and aids the transfer.

The component M reaches the downstream end of the round gutter truck 64 and is mainly transferred while being inclined to the sloped surface 65b of the V groove 65, but the component M can be transferred only in a single row provided on the sloped surface 65b. It is sent to the L-shaped track 74 of the second alignment block 72 via the shallow groove 66.

Referring to FIGS. 12 and 13, an L-shaped track 7
The four slopes 74b are the bottoms of the grooves formed so that the parts M can be transferred only in a single row. Therefore, some of the parts M in two rows may be inclined to the slopes 74a. However, these are blown up by the air jetted from the air jet nozzle 69 and are inverted to the slope 74b. Further, the width of the sloped surface 74a is slightly wider at the upstream end, but is cut from the downstream side as shown by the broken line to have a width corresponding to the thickness of one sheet of the component M, so that the components stacked in two or more layers. The M cannot be supported by the inclined surface 74a, and falls onto the block support plate 31 and is eliminated. That is, the part M is completely monolayered by passing through the second alignment block 72,
Single row.

The part M that has passed through the second alignment block 72
Are transferred to the round gutter truck 84 of the track block 82. At this time, the parts M that are congested by the air blown from the air jet nozzle 79 are separated and the transfer is assisted.

The part M is transported in a single layer, single row state on the circular gutter truck 84 to reach the downstream end, and the slope 85b of the V groove 85.
Then, it is transported to the slope 94b of the V-shaped track 94 in the front / back correction block 92 of FIG.
As shown in FIG. 16, when the component M passes over the optical path hole 103 that opens to the slope 94b, the optical sensor 101 below detects the front and back of the component M based on the intensity of the reflected light. When the optical sensor 101 detects the face-down component M, air is instantaneously ejected from the two air ejection holes 96 provided on the slope 94b, and the face-down component M is inverted to the slope 94a side and is transferred face-up. To be done. That is, the component M passes through the obverse / reverse correction block 92 and is tilted to the front by either the slope 94a or the slope 94b and is transferred to the downstream side.

The part M that has passed through the obverse / reverse correction block 92 contacts the guide member 115 attached to the track block 112, that is, the part M from the slope 94b.
Abut on the back surface, and the component M from the inclined surface 94a is abutted and transported on the side surface. During this time, the air ejected from the air ejection nozzle 119 suppresses the reversal of the component M and transfers it without changing its posture. It Then, when the rear end of the component M passes over the optical path hole 103, it moves to the round gutter track 114 through a small step. As described above, the arc-shaped track block 112 connected downstream of the front / back straightening block 92 is the other arc-shaped track block 42, 62,
Since it is set shorter than 82, and the round gutter track 114 having a semicircular cross section is formed in the track block 112, the part M is in contact with the transfer surface of the round gutter track 114 at four points and is stable. Since it is transferred to the linear vibrating parts feeder 200 after being adjusted to the front by the front and back straightening block 92, the front and back are not inverted and then fed to the linear vibrating parts feeder 200.

In the linear vibration parts feeder 200, the part M from the upstream round gutter truck 114 is the trough 2
21 is moved to a wide upstream part. To this place,
Since the air is ejected from the air ejection nozzle 128 provided in the upstream track block 112, the component M is smoothly sent to the midstream portion of the trough 221 having a single row width of the component M without overlapping. . In the midstream portion, as shown in FIG. 20, the optical sensor 226 monitors the front and back of the component M passing over the optical path hole 225 opened on the transfer surface of the trough 221, and when the component M facing down is detected. Air is instantaneously blown from the compressed air pipe 228 and jetted from the optical path hole 225, and the air from the air jet nozzle 131 is also assisted to remove the face-down component M to the receiving plate 238.

If there are parts M that are transferred in a stack inside the trough 221, the side walls 22 of the trough 221 are included.
1a has the same height as one of the parts M, and since the air from the air ejection nozzles 231 and 234 shown in FIGS. 19 and 20 is ejected from the side, it is easily blown off and the receiving plate Rejected towards 238. In this way, the single-layer, single-row surface-oriented parts M are discharged from the downstream end of the trough 221 of the linear vibration parts feeder 200. The component M removed to the receiving plate 238 is returned to the flat plate track 24 in the bowl 21 of the torsional vibration part feeder 100 via the reflux plate 208.

In the embodiment of the present invention, the first and second alignment blocks 52 and 72 are configured to perform the single layer formation and single row formation of the component M at the same time. The single layer formation and the single row formation may be performed independently.

Further, in the embodiment of the present invention, the component M is made into a single layer, a single row, and the front and back are made constant.
The component feeding apparatus of the present invention is similarly applied to the case where only the single layer formation and the single row formation are performed.

As described above, according to the present invention, a plurality of pairs of the arcuate track portion and the linear track portion are formed as the uppermost track portion on the substantially circular block support plate 31. However, at the downstream end of the circular gutter troughs 44, 64, 84 as arcuate track portions, V-shaped grooves 45, 65 having V-shaped cross sections whose depth gradually increases in the transfer direction, 85 are formed respectively, and the parts M are transferred along the sloping surface on the radially outer side, and the straight lines of the first alignment track 52 on the downstream side, the second alignment block 72, and the obverse / reverse correction block 92 which are connected to the component M. The tracks are transferred to the slopes on the radially outer side of the track portions, and a predetermined alignment action is performed on these linear track portions, that is, the first uppermost stream side.
In the aligning track 52, for example, 3 layers are reduced to 2 layers in the downstream flow rate, and then the second aligning block 7 is formed.
In 2a, a single layer and a single row are formed, and then the front / back straightening block 92
After all are turned face-up, they are fed to the next process through the last arcuate track portion 114, so that only the face-up part M is surely supplied in a single layer and a single row, and more than one pair of arc-shaped tracks is provided. Parts and parts M that were not subjected to a predetermined alignment action on the linear track part on the block support plate 31 to which the parts and the linear track part are attached are dropped here, and after the transfer stroke within 360 degrees is obtained, they are respectively guided. The plates 37 ₁ and 37 ₂ return them to the spiral track portion directly below in the bowl body. Moreover, the guide plates 37 ₂ on the downstream side are introduced to the start ends of the plurality of pairs of arc-shaped track portions and the linear track portions so that they are guided to the vicinity of the discharge end portion of the spiral track of the bowl main body. There is. Therefore, in the conventional examples other than the illustrated conventional example, generally, the parts M ascend in a flat track formed in a spiral shape on the inner peripheral wall surface of the bowl as a group. , Single layer and front and back sorting are performed, and even after that, even if it is introduced into the uppermost track part, as described above, the parts that are turned to the front with the three-point support with the transfer surface are facing backwards. However, according to the present invention, the elongated plate-shaped component M as shown in FIG. 1 can be surely supplied in a single-layer, single-row and face-up posture, and some alignment is performed. Since the parts dropped from the linear track portion are guided to the uppermost stage again by the rotation due to the torsional vibration of 360 degrees or less, the supply efficiency to the next process can be improved much more than the conventional case. The component M as shown in FIG.
It is a very entangled part, and if a large amount of it is put on the central bottom of the bowl from above, many parts in a entangled state may be almost dropped before being guided to the uppermost track part. Therefore, the loading amount of the bowl is limited to a certain amount, that is, if the remaining amount of the parts at the bottom of the center of the bowl is not less than the certain amount, there is almost a batch type loading by the robot. Since the operation cannot be performed and the supply speed of the parts to the next process is small in the past, the loading interval by such a batch type robot was large, but according to the present invention, the interval is small. The production efficiency can be greatly increased as compared with the conventional one.

V-grooves 45, 65, and 85 are formed on the downstream side of the round gutter tracks 44, 64, and 84. Among the pair of slopes, the slope on the radially outer side of the bowl has a bowl shape. Although it is certain that the centrifugal force due to the torsional vibration is greatly involved, the principle of operation will be further described with reference to FIG. 31 as follows.

The dimensional ratio and the shape are greatly different from those of the drawings showing the embodiments, but this is to make the principle easy to understand. In the bowl body B shown schematically, a spiral track T is shown, as is known, but at the discharge end a track corresponding to the derivation block 32 as a straight track part described above. The part t is connected to the circular gutter tracks 44, 64 and 84 of the above-mentioned embodiment, and the arcuate track parts Q ₁ , Q ₂ and Q ₃ are connected thereto. Although these are shown in an extremely exaggerated manner, first, Q ₁ is offset from the center O of the bowl as shown in the drawing (this is also shown in an exaggerated manner, but is actually in the bowl B). Is located at a position O ', and is formed with a radius r smaller than the radius R of the bowl B centered on this position, and each alignment block as a linear track portion corresponds to this downstream end J ₁ , J ₂ is connected,
According to the present embodiment, the linear alignment tracks J ₁ , J ₂ are formed so as to be on a circumference concentric with the center O of the bowl B (also shown exaggerated). . In addition,
The center O ″ of the second downstream arcuate track portion Q ₂ is also located at a position O ″ that is offset from the center O of the bowl B and the center O ′ of the upstream arcuate track portion Q ₁ , but its radius r is the same as that of the arcuate track portion Q ₁ on the upstream side.

Further, on the downstream side of each of the arcuate track portions Q ₁ and Q ₂ , the V-shaped cross section is directed toward the downstream side,
V-grooves, V ₁ and V ₂ whose depth gradually increases are formed. In the bowl B, the part M receives the torsional vibration force on the track T and reaches the linear discharge track portion t. From this point, the radius r of the arcuate track Q _{1 is} small. Although it is transferred by receiving the torsional vibration force in the support, as is clear from the figure, the torsional vibration of the bowl B is an arcuate vibration around the center O thereof, and therefore the first arcuate track portion. Since the extending direction of Q ₁ has different curvatures, as shown by the thin line W in the V grooves V ₁ and V ₂ , this shows the tangent line of the concentric circumference of the center O of the bowl B, but the arcuate track in this direction. Center G of part M of part Q ₁
Receives a transfer force due to vibration. For this reason, as described above, among the slopes forming the V grooves V ₁ and V ₂ , the slopes are transferred to the slopes on the outer side of the bowl diameter, and are transferred to the outer side of the straight track portions J ₁ and J ₂ to be described later. It can be accurately transferred to the side slope to undergo a predetermined alignment action. Although not shown, it is clear from the direction of the tangent line W that the radii of the circular gutter tracks Q ₁ and Q ₂ are larger than the radius R of the bowl. A biasing force is received as a vibration transfer force, and depending on the size of the radius of the arcuate track portions Q ₁ and Q ₂ , they are all transferred along the radially inward slope and are connected to this linear track portion. J ₁ , J ₂
The cross section of V is also formed in a V shape, but it is guided to the sloping surface on the inner side of the diameter, and in the above-mentioned embodiment, all the places where flow rate restriction is desired will fall, and further downstream. In the straight track portion J ₂ , it becomes impossible to reliably supply one row and one layer so that the front and back straightening track portions on the downstream side face up and to supply in a single layer and single row.

The present invention is embodied in the form described above, and has the following effects.

The arcuate track laid along the peripheral wall of the bowl of the torsional vibration parts feeder has a semicircular or semielliptical cross section, so that the elongated plate-shaped component is in stable contact with the transfer surface at four points. After being transferred and trimmed, or after removing a component that is not oriented in the prescribed direction, it is not necessary for the component to be inverted, so it is not necessary to return the inverted component into the bowl. The feeding efficiency is greatly improved.

Further, in the single layer forming means, single row forming means, surface leveling means, etc. of the parts, the parts are brought into surface contact with each other, and the linear flat track which is easy to narrow the size is used for the selection with high accuracy. Done.

Further, as described above, the arcuate track portion for transporting the elongated parts and the linear track portion for performing a predetermined alignment action are continuously formed on the uppermost step portion, but support them. The block support plate 31 is 360
The parts that have been extended within a degree but are not aligned are dropped onto the guide plates 37 ₁ , 3 by rotation of 360 degrees or less.
It is possible to be guided in a short time 7 ₂ is guided to the downstream side end portion of the uppermost portion, it can be greatly improved compared with the prior art supply efficiency to the next step.

Further, in the above-mentioned embodiments, the flow rate is reduced from the upstream side in order so that the straight line portion on the most downstream side as a single row and a single layer is subjected to the correction action. Since the track portion connected to is also arcuate and is supplied to the next step by being supported by four points, it is possible to reliably supply the single-layer and single-row elongated component M in the front direction to the next step.

Although not clearly described in the above embodiments, the component front / back correction unit detects the component M introduced to one of the slopes on the outer side, that is, the radially outward side, by the front / back detection means, and turns it face down. Although the parts of No. 1 and No. 2 were inverted on the slopes on the radially inner side by the air jet output, such a part front and back detecting means was developed by the applicant of the present invention. The arrangement of the present invention can be used to reliably guide the part M to the slope. That is, as described above, all the components can be tilted on the radially inward slope of the V groove formed on the downstream side of the arcuate track portion, so that all the radially outward slopes of the component front / back correction block can be tilted. Can be reliably led to.
