[Prior art and its problems]

 FIG. 8 is a perspective view of the coil spring m. When it is desired to supply the coil spring m to the next step in the direction of the arrow, as shown in FIG. 9, the coils cannot be supplied one by one in this posture. In order to cope with this, for example, in Japanese Utility Model Publication No. 52-4693, a spiral track formed on the inner peripheral wall of the bowl of the vibrating parts feeder has a substantially rectangular shape immediately above the discharge end. A casing with a closed space is attached, and this lower wall part is used as a guide plate for letting out air, and the entangled coil spring on the track passing below this is lifted by the air blown from below. The coil spring is blown away to collide with the upper wall to loosen the entanglement, and the coil spring dropped downward is supplied to the next process.

However, with such a coil spring entanglement device, a large amount of air must be jetted from below the truck, which consumes a large amount of compressed air, and the upper wall of the casing has a large amount of air consumption. After colliding, it may be entangled again when it falls.

Further, according to the coil spring feeding device of Japanese Patent Publication No. 55-5445, a coil-impact body in the shape of a cap is provided in the center of the bowl of the vibrating part feeder, and a coiled coil spring guided below the coil impact body. Air is blown from the bottom wall of the bowl to collide with the inner wall of Jinkasa to loosen the entangled coil, but it still requires a large amount of air to be ejected and, after colliding with Jinkasa, entangles again. There were many things.

In view of the above-mentioned problems, the present applicant previously fixed a substantially horizontally arranged cylindrical body and an inner wall of the cylindrical body fixed to the upper wall of the cylindrical body at a predetermined pitch along the axis. A plurality of flat plates and an air ejection port provided in the bottom wall portion at one end of the cylindrical body described above. An entangled coil spring is supplied to one end of the cylindrical body so that air is ejected from the air ejection port. Is ejected, the coil spring is pressure-fed along the inner wall surface of the cylindrical body, and is transferred along the axis of the cylindrical body while colliding with the flat plate, and seen from the other end side of the cylindrical body. We proposed a coil spring entanglement device which is characterized in that a coil spring that has been loosened is discharged (Japanese Patent Application No. 4-80934).

FIG. 10 and FIG. 11 show the entire coil spring entanglement device according to its specific example. This device is mainly composed of a vibrating parts feeder 1, a vibration hopper V for inserting the coil spring into the vibrating parts feeder, and a vibration device. It consists of a linear vibration feeder 3 connected to the discharge end of the parts feeder 1 and an entanglement loosening device 4 arranged in the vicinity of the vibration parts feeder 1.

The vibrating parts feeder 1 is constructed in a known manner, but is provided with a bowl-shaped container (bowl) 5 in which a spiral track 6 is wound around the inner peripheral wall thereof, and the bottom part thereof is integrally formed. The movable core 7 fixed to the base plate 8 and the lower base block 8 are connected by a leaf spring 11 arranged at equal angular intervals. An electromagnet 10 around which a coil 9 is wound is fixed on the base block 8 and faces the movable core 7 with a gap. The torsional vibration drive unit is configured as described above, but the whole is covered by the cylindrical cover 12, and the whole vibration parts feeder 1 is supported on the base 16 by the vibration isolating rubber 13. There is. Further, the base 16 supports the entire vibrating parts feeder 1 on the base plate 14 by means of height adjusting screws 15 so that the height of the vibrating parts feeder 1 can be adjusted with peripheral devices.

The vibration hopper V is composed of a hopper H that stores a large amount of coil springs and an electromagnetic vibration feeder 2. The electromagnetic vibration feeder 2 shown in the drawing is arranged at the lower end opening of the hopper H. The coil spring is fed from the hopper H by vibrating the trough 40 to supply the coil spring m to the central portion of the bowl 5 of the vibrating parts feeder 1. The trough 40 is connected to a base block 41 by a pair of front and rear leaf springs 46 and 47, and an electromagnet 45 around which a coil 44 is wound is fixed to the base block 41. The electromagnetic vibration feeder 2 is configured as described above, but it is supported on the mount 42 by the coil spring 43.

The linear vibrating feeder 3 is also configured as described above, but the coil spring supply track 17 and the alignment track 22 are respectively provided at the discharge end of the track 6 formed on the inner peripheral wall of the bowl 5. Connected and adjacent to the ends of the alignment track 22 with a gap of s, a trough 23 is arranged, which is fixed to the leaf spring mounting block 26 by means of mounting members 24, 25, which also It is connected to the base block 27 by a pair of front and rear leaf springs 28 and 29. An electromagnet 32 around which a coil 31 is wound is fixed on the base block 27 and faces the movable core 30 fixed to the leaf spring mounting block 26 with a gap. The linear vibration feeder 3 is constructed as described above, but the whole is supported on the base 34 by the vibration-proof rubber 33, and this is mounted on the column 35 via the height adjusting screw. 16 is supported.

At the end of the track 6 of the bowl 5, a notch 5b having a height slightly larger than the diameter of the coil spring m is formed at the end of the side wall 5a, and the track on the downstream side is formed. The end 6a of 6 is inclined downward toward the radially outer side of the bowl 5.

A coil spring supply track 17 is integrally provided with the bowl 5 in the radial direction of the notch 5b in the vicinity of the notch 5b and is connected to an alignment track 22 concentric with the bowl 5. A cutout 21 is provided at the discharge end to make this portion a narrow path. That is, the coil springs m that have reached up to this point are arranged in one row and connected to the linear vibration feeder 3 on the downstream side.

A communication passage 18 is integrally formed in the bowl 5 below the end portion 6 a of the truck 6, so that the entangled coil spring m can be guided to the entanglement device 4. It is configured.

As shown in FIG. 11, the communication passage 18 communicates with an arc-shaped communication track 19 in parallel with the alignment track 22, and a circular opening 20 is formed in the bottom wall portion of the communication path 18. The entangled coil spring m is guided to the entanglement device 4 through the.

As shown in FIG. 15, the entanglement device 4 includes an arc-shaped introduction guide pipe 60 aligned with the opening 20 as a whole, a cylindrical body 61 connected on the discharge side, and an air-tight seal on the discharge side. It is composed of a vertical guide pipe 69 connected thereto, a curved lead-out guide pipe 62 airtightly connected to the upper end portion thereof, and a coil spring discharge port portion 63 formed integrally therewith.

The coil spring discharge port portion 63 is formed to have a diameter larger than the diameter of the lead-out guide pipe 62, and a net 66, a sponge 65, and a thin plate 67 are attached to the opening end portion by a mounting member 64. Further, the opening 68 formed in the bottom wall portion is formed so as to face the bottom wall surface of the bowl 5 of the vibrating parts feeder 1.

As shown in FIG. 16, the cylindrical body 61 is composed of semi-cylindrical bodies 61 A and 61 B. The flange portions 70 and 71 are aligned with each other, and the bolt 73 is inserted into the bolt insertion hole 74. By interposing the washer 76, the nut 75 is screwed and tightened, and these are integrated to form the cylindrical body 61. Further, a circular lid 92 is applied to the semicircular flange portions 93 and 94, and is fixed to the cylindrical body 61 by bolts 73 as well. The above-mentioned introduction guide pipe 60 is integrally fixed to the lid 92, and the vertical guide pipe 69 is fixed to the extension portion 72 of the flange portion 71 on the other end side.

A rectangular flat plate 81 is fixed to the upper wall of the upper half-cylindrical body 61A of the cylindrical body 61 at a predetermined pitch. In this specific example, this pitch is slightly smaller than the height of the coil spring m. small. A partition wall 90 is formed slightly downstream of the central portion of the upper semi-cylindrical body 61A, and a viewing window 82 made of a transparent material is provided between the partition wall 90 and the end wall portion 91 of the upper semi-cylindrical body 61A. The fastener 83 is attached so as to be openable and closable.

As described above, the cylindrical body 61 is formed as a hermetically sealed structure, and the air jet pipe 77 is attached to the bottom wall portion at one end thereof, and the air jet port 77a is shown in FIG. As shown in FIG. 18, although it is substantially tangential to the circumferential surface of the cylindrical body 61, in this specific example, it is further inclined in the axial direction of the cylindrical body 61. The entanglement device 4 configured as described above is supported by the base 16 via the mounting plate 78 and the L-shaped supporting member 79, which are vertically mounted on the bottom wall surface of the cylindrical body 61, through the bolts 80. . The air jet pipe 77 is connected to a compressed air supply pipe 85, which is connected to a solenoid valve (not shown) and is also opened / closed by a controller (not shown).

The vibrating parts feeder 1 is further provided with a sky detection device 48, which has a publicly known structure, but is shown in FIG. 11 via an arm 50 on a column 49 fixed to the base 16. As clearly shown, the flat plate 51 is swingably attached. When the coil spring m is not present at the lower end of the flat plate 51, a limit switch (not shown) installed on the bottom wall surface of the bowl 5 is turned on. However, when the coil spring m comes under this and the flat plate 51 is raised, the limit switch is turned off.

The coil spring entanglement device 4 according to this example is configured as described above. Next, this operation will be described.

A large number of coil springs m are inserted into the hopper H (not shown). When the electromagnetic vibration feeder 2 is driven, the coil springs are sequentially cut out from the hopper H, and the coil springs are generated by the vibration of the trough 40. m is supplied to the bowl 5 of the vibrating parts feeder 1.

In the vibrating parts feeder 1, an alternating magnetic attraction force is generated between the electromagnet 10 and the movable core 7 by energizing the coil 9 with an alternating current, which causes the bowl 5 to perform a known torsional vibration. This causes the coil spring m to rise above the track 6 in the bowl 5, but at this time, since a large amount of the coil spring m exists in the bowl 5 as shown in FIG. The flat plate 51 is displaced upward by the coil spring m to turn off the limit switch. Therefore, the driving of the electromagnetic vibration feeder 2 is stopped.

In the bowl 5, the coil spring m is transferred along the track 6. As shown in FIG. 14, when the coil spring m is moved to the vicinity of the end of the track 6, the side wall 5 a of the bowl 5 is reached. The coil spring m which is not entangled in the notch 5b formed in the above passes through here and slides down to the coil spring supply track 17 side, and thereafter reaches the notch 21 of the alignment track 22 as clearly shown in FIG. And one line and are supplied to the linear vibration feeder 3. The linear vibrating feeder 3 maintains its posture, and the one end is supplied from the discharge end to the next step (not shown). On the other hand, as clearly shown in FIG. 14, the coiled coil spring m cannot pass through the notch 5b, and the end 6a of the track 6 is inclined downward in the radial direction. The communication track 18 is dropped into the communication passage 18, and further, the communication track 19 is transferred by vibration, drops through the opening 20, and is guided into the entanglement device 4.

Since the compressed air is ejected from the air ejection port 77a arranged at one end of the cylindrical body 61, the coil spring m introduced in the vicinity of the compressed air is applied to the inner peripheral wall surface of the cylindrical body 61 by the compressed air. When it reaches the upper wall portion of the cylindrical body 61 while being helically moved, it collides with the flat plate 81. At this time, the space corresponding to the winding pitch of the entangled coil spring is sandwiched between the flat plates 81, and air pressure is applied to the entangled coil spring m to loosen the entanglement. Further, the coil spring m following this collides with the coil spring m, whereby the entanglement of the coil spring is surely disentangled. The coil spring m performs a helical motion along the axis of the cylindrical body 61 as described above, so that when it collides with the partition wall 90, its entanglement is completely disentangled and the helical motion is continued. As a result, the coil spring m of the cylindrical body 61 reaches the end portion, soars upward on the air ejection port 84a that ejects air upward, rises on the vertical guide pipe 69, and further passes through the curved lead-out guide pipe 62. Although it collides with the wall formed by the net 66 and the sponge 65 provided at the end of the spring discharge port 63, the buffer spring of the sponge 65 causes the coil spring m to vibrate through the opening 68 without any damage. It is returned to the bowl 5 of the parts feeder 1. The untangled coil spring m has risen up the track 6 as clearly shown in FIG. 14 and has already been untangled, so it passes through the notch 5b and is guided onto the coil spring supply track 17. Then, it is supplied to the next process from the linear vibration feeder 3. Even if the entanglement device 4 does not entangle the entanglement, when it is returned to the bowl 5 and reaches the notch 5b shown in FIG. 14, the inside of the communication passage 18 does not pass therethrough. Then, it is subjected to the same action again by the entanglement device 4.

The entanglement loosening device 4 according to the present specific example is configured and operates as described above, so that the coil spring is pressure-fed in the closed space A in the cylindrical body 61, so that air is wasted. Efficient helical motion is performed without consuming the air, and the coil spring loosening action described above reduces the air consumption compared with the conventional entanglement loosening device, and in the past it was blown upward to the upper wall. There was a risk of entanglement because it was allowed to fall naturally after the collision, but in this example, a helical motion was performed, during which the plate 81 collided many times and the space corresponding to the coil pitch was changed to the plate. The 81's pinching action surely loosens the entanglement and does not cause the entanglement again.

The entanglement device for coil springs developed by the applicant of the present invention is configured as described above and operates and obtains the intended effect. However, it has the following drawbacks. there were.

That is, the amount of air required in this example was extremely small as compared with the conventional entanglement device, but a large amount of compressed air was still required, and accordingly, the compressed air was also increased. Is not desirable in the work environment because of the large sounding noise, and it depends on the pressure of compressed air and the amount of air blown out, but it is difficult to blow out a tangled coil with a large coil m. Therefore, it was the object to be treated that was difficult to loosen the entanglement.

FIG. 19 shows another conventional example of the entanglement device for the coil spring m. The mounting portion 192 at the upper end of the side wall 191 of the cylindrical container 190 is fixed to the stationary portion 194 by a bolt 193, and the bottom plate 195 is rotated by a motor 196 independently of the side wall 191. Further, at the lower part of the side wall 191, only the coil spring m in which the entanglement is loosened is discharged to the position of the upper surface level of the bottom plate 195, and the entangled coil spring m is not discharged, that is, slightly larger than the diameter of the coil spring m. An opening 197 having a height is provided. Coil spring m I from being supplied as the upper arrow P is the bottom plate 195 to rotate as viewed from colliding with the side wall 191 is recoiled as arrow Q _3, Q ₄ is loosened, as an arrow Q ₅ Then, it falls on the bottom plate 195 and is discharged from the opening 197 as shown by an arrow R. However, in the case of such a device, the entanglement is difficult to be unraveled only by the collision of the entangled coil spring m with the side wall 191, and even if it is once unraveled, it is often dropped on the bottom plate 195 and reentangled. Since the entangled coil spring m is mixed on the bottom plate 195, the coil spring m stays inside the cylindrical container 190 without smoothly discharging the coil spring m loosened from the opening 197. Since the overloaded motor 196 may be burnt out, there is a drawback that the unraveled coil spring m must be manually unraveled.

【Example】

 Hereinafter, a coil spring entanglement device according to an embodiment of the present invention will be described with reference to the drawings. It should be noted that the same parts as those of the above-described specific example are denoted by the same reference numerals, and the description thereof will be omitted. Only the part related to the present invention will be described in detail.

1, 2 and 3 are views showing a coil spring entanglement device 140 according to an embodiment of the present invention, which is an entanglement device shown in FIG. This is a part corresponding to the comb device 4. 1 is a partially broken side view, FIG. 2 is a front view seen from the supply side of the coil spring m of FIG. 1, and FIG. 3 is a sectional view taken along line [3]-[3] of FIG. .

As shown in FIG. 1, FIG. 2 and FIG. 3, the entanglement device 140 of the present invention as a whole has an arcuate introduction arranged in a circular opening 20 in a connecting track bottom wall portion 21 of a vibrating parts feeder. A guide pipe 160, a cylindrical body 161 which is connected to the discharge side and is arranged substantially horizontally, and has an opening 180 downward along the axis of the guide pipe 160, and a gap 182 is formed at a side edge portion of the opening 180. It is composed of a longitudinal rotary member 164 arranged so as to project upward and rotated by a motor 162 around its axis by a belt 163, and a guide pipe 169 connected to the discharge side of the cylindrical member 161. . A plurality of flat plates 181 are fixed to the top wall portion of the inner wall of the cylindrical body 161 at a predetermined pitch along the axis of the cylindrical body 161, and the mounting flange 165 of the introduction guide pipe 160 has a coil spring m. The auxiliary air jet pipe 177 for assisting the transfer of the compressed air is connected to the auxiliary air jet pipe 177. The cylindrical body 161 is fixed substantially horizontally to a part of the vibrating parts feeder, for example, the bottom wall portion 21 of the connecting track with bolts 166, and the longitudinal rotating body 164 has a pair of support legs 168 via ball bearings 167. Supported by. Although not shown in the drawings, the guide pipe 169 on the discharge side is, needless to say, provided with its discharge port facing the track or bottom wall surface of the bowl of the vibrating parts feeder.

The coil spring entanglement device 140 according to the embodiment of the present invention is configured as described above. Next, its operation will be described.

The entangled coil spring m, which is transferred by the vibration of the oscillating parts feeder, drops through the circular opening 20 of the bottom wall 21 of the connecting track, and is introduced into the entanglement device 140, is rotated by the rotating longitudinal rotating body 164. It is bounced and collides with the flat plate 181 along the path indicated by arrows Q _{1 and} Q _{2 in} FIG. 3, for example. At this time, the space corresponding to the winding pitch of the entangled coil spring m is sandwiched between the flat plates 181 and the coil spring m subsequent to the coil spring m collides with the coil spring m without fail. Will be loosened. In addition to recoil on the surface of the rotating long rotary body 164, the coil spring m is transferred to the discharge side by the aid of the jetting air, and the coil spring m reaching the guide pipe 169 is almost completely removed. The entanglement is loosened. Since the guide pipe 169 is arranged at the same height as the upper surface of the longitudinal rotary member 164, it is not necessary to pneumatically transport the coil spring m upward as in the above-described specific example shown in FIG.

The entanglement loosening device 140 according to the embodiment of the present invention is configured as described above and performs an action. The entanglement device 140 rotates regardless of the air ejecting the coil spring m from colliding with the flat plate 181. Due to the recoil on the surface of the long rotator 164, air is used only to assist the transfer, so the amount of air required is significantly reduced. It will be drastically reduced. Furthermore, since the collision with the flat plate 181 depends on the recoil of the rotating surface of the long rotary body 164 having a large inertial weight, the coil spring m having a large weight per piece can be sufficiently treated. have. The loosening of the entangled coil spring m is not a mere collision with a wall but a collision with a flat plate 181 fixed at a predetermined pitch, and the flat plate 181 collides with the flat plate 181 many times while moving to the discharge side. In this way, since the loosened coil spring m is moved to the discharge side in this way, it is very unlikely that the loosened one will fall and be re-entangled, as in the above-described specific example. .

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.

For example, in the above-described embodiment, air jetting is used to assist the transfer of the coil spring m, but instead of the arrangement of the auxiliary air jetting pipe 177, the cylindrical body 161 and the longitudinal rotating body combined with it are provided. 164 may be inclined downward in the axial direction toward the downstream side to assist the transfer in the axial direction.

Further, FIG. 4 shows a modified example of the cylindrical body, and the same reference numerals are given to the respective parts corresponding to the components of FIG. 3 of the embodiment, and the description thereof will be omitted. . That is, in this modification, the cylindrical body 161 is replaced by a rectangular tubular body 171 lacking one surface. The rectangular tubular body 171 itself is manufactured, or a flat plate or a rod-shaped body for the tubular body is formed. This has the effect that the parts can be easily fixed.

5 and 6 show an example of a rod-shaped member with which the entangled coil spring m should collide, and a round rod having a diameter equivalent to the thickness of the flat plate 181 of the embodiment is U-shaped. The bar-shaped member 183 is shown. That is, FIG. 5 is a cross-sectional view corresponding to FIG. 3 of the embodiment, and the same reference numerals are given to the respective parts of the corresponding components, and the description thereof will be omitted. FIG. 6 is a partial cross-sectional view taken along the line [6]-[6] of FIG. It is within the scope of the technical idea of the present invention that the rod-shaped member has a triangular shape, a polygonal shape, a ring shape, or a single linear shape other than the U-shape shown in FIGS.

Further, FIG. 7 shows a modification of the position for fixing the flat plate 181 and corresponds to FIG. 3. The same reference numerals are given to the respective parts of the corresponding components, and the description thereof will be omitted. That is, in this modified example, the entangled coil spring m is recoiled by the longitudinal rotor 164 and is supplied to the position where the energy at the time of colliding with the flat plate 181 is maximized, that is, the surface of the longitudinal rotor 164. Although it varies depending on the place, as an example, the flat plate 181 is fixed to the inner wall portion on the upper right side at an angle of 45 ° with reference to the axis of the cylindrical body 161.

Furthermore, although the longitudinal rotary member 164 is shown as a cylinder in the above embodiment, it may be a polygonal cylinder.

Although the coil spring entanglement device has been described in the above embodiments, it is assumed that a coil-shaped component such as an electron filament is also equivalent to the coil spring in the present invention.
