Description

The present invention relates to a parts alignment and supply device for conveying parts made of conductive material, and more particularly to a parts alignment and supply device and a parts supply method using the same that can prevent parts made of conductive metal or the like from being supplied in an overlapping state.

Conventionally, bowl-type vibratory parts feeders and linear-type vibratory parts feeders are known to be used as a means for aligning and supplying parts. In a bowl-type vibratory parts feeder, multiple parts are placed into a bowl that constitutes a moving part, and the bowl vibrates in a circumferential direction, aligning the multiple parts placed in the bowl and transporting and supplying them in the direction of the vibration.

When the part supply path is long, a linear vibratory parts feeder with a straight transport path is used, and it is known that parts aligned by a bowl-type vibratory parts feeder are transported in a straight line, for example, horizontally.

To prevent overlapping parts from being conveyed, these vibratory part feeders typically use a detection device such as an optical sensor to measure the distance to the parts, and use the detection output to detect whether the parts are overlapping. If overlapping parts are detected, they are either ejected or a physical shutter is used to remove the overlapping parts, preventing them from being fed in an overlapping state (see, for example, Patent Document 1).

However, because parts are transported using bowl-type vibratory parts feeders or linear-type vibratory parts feeders while vibrating, methods that measure the distance to the parts using detection means such as optical sensors may not be able to detect overlapping parts if the vibration amplitude of the vibratory parts feeder exceeds the thickness of the parts.

In other words, when trying to detect the state of parts using an optical sensor, the vibration of the vibrating parts feeder must be taken into account and the position of parts that exceed the vibration amplitude must be measured. However, if the thickness of the parts to be detected is thinner than the vibration amplitude, it is rare for the parts to exceed the vibration amplitude, making it difficult to detect overlapping parts with a high probability.

For example, if the vibration amplitude of a vibrating parts feeder is 0.1 mm or more, and the thickness of the parts is less than that, say 0.03 mm, even if these relatively thin parts are overlapping, the increase in thickness due to the overlapping will be within the vibration amplitude range, making it impossible to determine the overlapping and therefore preventing the overlapping from being eliminated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a parts aligning and feeding device that can prevent overlapping of parts even when the parts are relatively thin, and a parts feeding method using the same .

The present invention is an improvement to a parts alignment and supply device that includes a linear vibratory parts feeder with a straight transport path and a vibrating transport body that moves parts made of conductive material placed on the transport path by vibrating them, a bowl-type vibratory parts feeder that sequentially supplies parts to the end of the transport path, and a return vibratory parts feeder that is located adjacent to the linear vibratory parts feeder and returns parts that have fallen off the transport path to the bowl-type vibratory parts feeder .

Its distinctive configuration is that the transport path is formed at an angle downward toward the return vibration parts feeder and has a back support surface portion that supports the back surfaces of the parts, and the linear vibration parts feeder is equipped with a detection means for detecting the state of the parts moving along the transport path and a discharge means for removing the parts from the transport path based on the detection output of the detection means, the detection means being a magnetic induction type non-contact sensor that is embedded in the back support surface portion and detects changes in impedance associated with the connection and disconnection of parts moving along the transport path, and the discharge means is formed in the back support surface portion downstream of the magnetic induction type non-contact sensor and has a blow-out hole that blows out air to remove the part from the transport path when the detection output of the detection means exceeds a predetermined threshold.

The magnetic induction type non-contact sensor is preferably provided by being embedded in the conveying path so that the detection surface is flush with the back support surface portion .

The device may further include a controller that compares the detection output of the magnetic induction type non-contact sensor with a threshold value, and drives the exhaust means to blow air out of the blowout holes when the detection output exceeds the threshold value.

Another aspect of the present invention is a parts supplying method using the above-mentioned parts aligning and supplying device, in which parts made of conductive material are sequentially supplied by a bowl-type vibrating parts feeder, and are then placed on a conveying path and moved so that the inclined back support surface of a vibrating conveying body supports the back surfaces of the parts .

A distinctive feature of this system is that it uses a magnetic induction non-contact sensor embedded in the rear support surface to detect changes in impedance that accompany the connection and disconnection of parts moving along the transport path, and when the detection output of the magnetic induction non-contact sensor exceeds a predetermined threshold , air is blown out from a blow-out hole formed in the rear support surface downstream of the magnetic induction non-contact sensor to remove the part from the transport path , and the vibrating parts feeder returns the part that has been removed from the transport path to the bowl-type vibrating parts feeder .

In the parts alignment and supply device and the parts supply method using the same of the present invention, the state of the parts is detected by a magnetic induction type non-contact sensor, so even if the thickness of the parts to be detected is thinner than the vibration amplitude, it is possible to detect overlapping parts with a high probability, and if the detection output is used by the discharge means to remove the parts from the conveying path, it is possible to reliably prevent overlapping parts from being supplied, even if the parts are relatively thin.

Next, a detailed description of an embodiment of the present invention will be given with reference to the drawings.

Figures 1 and 2 show a parts alignment and supply device 9 according to the present invention. This parts alignment and supply device 9 comprises a linear vibratory parts feeder 20 having a vibratory conveying body 24 with a straight conveying path 25 formed thereon, a bowl-type vibratory parts feeder 10 that sequentially supplies parts 14 to the starting end of the conveying path 25 in the linear vibratory parts feeder 20, and a return vibratory parts feeder 40 that returns parts 14 that have fallen off the conveying path 25 in the linear vibratory parts feeder 20 to the bowl-type vibratory parts feeder 10.

The bowl-type vibratory parts feeder 10 comprises a bowl 11 into which parts 14 are fed, and a vibrator 12 (Figure 2) that vibrates the bowl 11 in a circumferential direction. As shown in Figure 1, a spiral conveying path 13 is formed on the inner periphery of the bowl 11, and the bowl-type vibratory parts feeder 10 is configured to convey parts 14 fed into the bowl 11 along the spiral conveying path 13 formed on the inner periphery by vibrating the bowl 11 in a circumferential direction using the vibrator 12.

Examples of the vibrator 12 include an electromagnet or a piezoelectric element. However, the vibrator 12 may be a mechanical type that electrically drives a mechanical mechanism such as a cam or link to vibrate the bowl 11, or a pneumatic type that uses air to vibrate the bowl 11. Here, reference numeral 12a in Figure 2 denotes a vibration-isolating rubber 12a that absorbs vibrations from the vibrator 12 that vibrates the bowl 11 and reduces the amount transmitted to the installation location 8.

As shown in Figure 1, the bowl 11 has a circular bottom 11a and a peripheral wall 11b that rises from the periphery to form a cone, and the spiral conveying path 13 is formed so that it spirals upward from the periphery of the bottom 11a to the inner surface of the peripheral wall 11b. As a result, when the bowl 11 is vibrated by the vibrator 12 (Figure 2), the bowl 11 vibrates in the circumferential direction, causing multiple parts 14 placed in the bowl 11 to be conveyed along the spiral conveying path 13.

A notch 11c is formed in the peripheral wall 11b, into which the starting end of the vibrating conveyor 24 of the linear vibrating parts feeder 20 enters, and the spiral conveying path 13 extends up to this notch 11c. In other words, the end of the spiral conveying path 13 formed in this notch 11c is configured to become the parts discharge outlet 11d of this bowl-type vibrating parts feeder 10.

In this embodiment, the parts 14 are thin, rectangular plates made of conductive metal. As shown in Figure 1, the bowl-type vibratory parts feeder 10 is configured to align multiple parts 14 placed in the bowl 11 while vibrating them in the circumferential direction, and then sequentially discharge the aligned parts 14 from the parts discharge port 11d located on the outer periphery.

The linear vibratory parts feeder 20 connected to this bowl-type vibratory parts feeder 10 transports the parts 14 aligned and dispensed by the bowl-type vibratory parts feeder 10 in a straight horizontal direction. As shown in Figure 2, it has a base 21 installed at the installation location 8 with a vibrator 22 mounted on top, and a linear vibration base 23 that vibrates back and forth in the longitudinal direction due to the vibrator 22.

The base 21 is placed at the installation location 8, and the vibrator 22 is exemplified by an electromagnet or a piezoelectric element. However, as with the bowl-type vibratory parts feeder 10, the vibrator 22 may be a so-called mechanical type that electrically drives a mechanical mechanism such as a cam or link to vibrate the linear vibration base 23, or a so-called pneumatic type that uses air to vibrate the linear vibration base 23.

A vibrating conveyor 24 is provided on the linear vibrating base 23, vibrating together with the linear vibrating base 23 to convey the mounted parts 14 in the longitudinal direction. The vibrating conveyor 24 in this linear vibrating parts feeder 20 is a relatively long rod-shaped member extending in the conveying direction, and a linear conveying path 25 along which the parts 14 are conveyed is formed on its upper surface, extending longitudinally.

As shown in Figures 1 and 2, this linear vibratory parts feeder 20 is installed at the installation location 8 with its base 21 connected to the bowl-type vibratory parts feeder 10, with the starting end of its vibratory conveying body 24 inserted into the notch 11c of the bowl 11 of the bowl-type vibratory parts feeder 10.

In other words, the linear vibratory parts feeder 20 is installed adjacent to the bowl-type vibratory parts feeder 10 so that the parts 14 discharged from the parts discharge port 11d of the bowl-type vibratory parts feeder 10 are loaded at the beginning of the linear conveying path 25 extending horizontally in the linear vibratory parts feeder 20.

As shown in Figures 3 and 4, the linear conveying path 25 of the vibrating conveying body 24 is formed with a back support surface 25a that supports the back surface of the rectangular part 14 in an inclined state, and a long side support surface 25b that is perpendicular to the back support surface 25a and supports the long side of the part 14.

For this reason, parts 14 guided from the bowl-type vibratory parts feeder 10 onto the linear conveying path 25 of the linear vibratory parts feeder 20 are configured to be conveyed longitudinally along the linear conveying path 25 of the linear vibratory parts feeder 20 with their back surfaces supported by the back support surface portion 25a and their long sides perpendicular to the back surfaces inclined so that they are supported by the long side support surface portion 25b.

As shown in Figures 1 and 2, this vibrating conveyor 24 is provided with a detection means 27 that detects the state of the parts 14 being conveyed along the linear conveying path 25, and a discharge means 30 that removes the target parts 14 from the linear conveying path 25 based on the detection output of the detection means 27.

A distinctive feature of the present invention is that the detection means is a non-contact sensor 27 provided on the vibrating conveyor 24 that detects the contact or separation of parts 14 being conveyed along the linear conveying path 25, and the ejection means 30 is configured to remove the parts 14 from the linear conveying path 25 when the detection output of the detection means 27 exceeds a predetermined threshold value L (Figures 5 and 6).

The non-contact sensor 27 may be, for example, a high-frequency oscillation type that uses electromagnetic induction, a magnetic type that uses a magnet, or a capacitance type that uses changes in electrostatic capacitance. However, in this embodiment, in which the parts 14 made of conductive metal are to be transported, a magnetic induction type non-contact sensor 27 is used as the non-contact sensor 27, which detects changes in impedance associated with the contact and separation of parts 14 transported on the linear transport path 25.

As shown in Figure 3, the magnetic induction type non-contact sensor 27 used in this embodiment has a detection coil (not shown) required for electromagnetic induction attached to the tip of a cylindrical main body 27a, with the tip edge of the main body 27a serving as the detection surface 27b. The magnetic induction type non-contact sensor 27 is embedded in the linear conveying path 25 so that the detection surface 27b is flush with the linear conveying path 25.

Specifically, the vibrating conveyor 24 has an insertion hole 24a formed in it that is perpendicular to the back support surface 25a and has an inner diameter slightly larger than the outer diameter of the non-contact sensor 27. The cylindrical main body 27a of the magnetic induction type non-contact sensor 27 is inserted into this insertion hole 24a, and the main body 27a is fixed to the insertion hole 24a so that the detection surface 27b at its tip is flush with the back support surface 25a of the linear conveyor path 25.

The detection output of the detection means 27 thus provided is connected to the control input of the controller 31, and the controller 31 is configured to control the discharge means 30 (Figure 1) based on the detection output of the detection means 27.

In this embodiment, the ejection means 30 uses air pressure to remove the target part 14 from the linear conveying path 25. As shown in Figures 5 and 6, the vibrating conveying body 24 has a blow-out hole 24b formed adjacent to the downstream side of the insertion hole 24a, perpendicular to the back support surface portion 25a of the linear conveying path 25. As shown in Figure 4, an air supply pipe 33 from a compressor 32 (not shown) is connected to this blow-out hole 24b.

This air supply pipe 33 is provided with a normally closed valve 34, to which a control output from the controller 31 is connected. When the detection output of the magnetic induction non-contact sensor 27, which serves as the detection means, exceeds a predetermined threshold L (FIGS. 5 and 6), the controller 31 opens this valve 34 for a short time, causing compressed air to be ejected from the compressor 32 via the air supply pipe 33 and through the blow-out hole 24b. As shown by the dashed line in FIG. 4 and FIG. 6(c), any part 14 moving along the linear conveying path 25 and positioned so as to block the blow-out hole 24b is blown out of the linear conveying path 25 as shown by the solid arrow in FIG. 4 and FIG. 6(d), thereby removing the part 14 from the linear conveying path 25.

As shown in Figures 1 and 2, this linear vibratory parts feeder 20 is adjacent to a return vibratory parts feeder 40 that receives parts 14 removed from the linear conveying path 25 and returns them to the bowl-type vibratory parts feeder 10.

This return vibration parts feeder 40 has the same structure as the linear vibratory parts feeder 20, except for the shape of the vibratory conveying body 44. As shown in Figures 3 and 4, the entire upper surface of the vibratory conveying body 44 is formed flat, forming the conveying path 45. The return vibration parts feeder 40 is positioned adjacent to the linear vibratory parts feeder 20 so that parts 14 removed from the straight conveying path 25 of the linear vibratory parts feeder 20 can fall onto and be loaded onto the conveying path 45, and the discharge end of the conveying path 45 reaches the bowl 11 of the bowl-type vibratory parts feeder 10 (Figure 1).

The configuration of this return vibration parts feeder 40, excluding the shape of the vibrating conveying body 44, is identical to that of the linear vibrating parts feeder 20, except that it is mounted so that the conveying direction faces the bowl-type vibrating parts feeder 10. For this reason, the reference numerals for each component of the return vibration parts feeder 40 are indicated by adding 20 to the reference numerals of the corresponding components of the linear vibrating parts feeder 20, and further explanation will be omitted.

Next, we will explain the operation of the parts alignment and supply device configured in this way.

As shown in Figure 1, parts 14 to be aligned and fed by this part alignment feeder 9 are placed into the bowl 11 of a bowl-type vibratory parts feeder 10. The bowl-type vibratory parts feeder 10 is then operated to vibrate the bowl 11 circumferentially using a vibrator 12, thereby aligning and transporting the multiple parts 14 placed in the bowl 11 circumferentially on the spiral transport path 13.

In the linear vibratory parts feeder 20, the bowl-type vibratory parts feeder 10 is operated, and at the same time, its vibrator 22 vibrates the linear vibratory base 23. As shown in Figure 1, the vibration of this linear vibratory base 23 transports the parts 14 aligned by the bowl-type vibratory parts feeder 10, from its part discharge outlet 11d to the linear transport path 25 on the vibratory transport body 24 of the linear vibratory parts feeder 20, in a straight line horizontally.

As shown in Figures 3 and 4, the linear conveying path 25 of the vibrating conveying body 24 of the linear vibrating parts feeder 20 has a back support surface 25a that supports the back surface of the rectangular part 14 in an inclined state, and a long side support surface 25b that supports the long sides of the part 14 perpendicular to the back support surface 25a. Therefore, the part 14 guided along the linear conveying path 25 is conveyed in the longitudinal direction in an inclined state so that its back surface is supported by the back support surface 25a and its long side perpendicular to the back surface is supported by the long side support surface 25b.

As shown in Figure 1, the vibrating transport body 24 of the linear vibrating parts feeder 20 is provided with a non-contact sensor 27 that detects the state of the parts 14 being transported on its linear transport path 25, and is equipped with a discharge means 30 that removes the parts 14 from the linear transport path 25 based on the detection output of this non-contact sensor 27.When the detection output of the non-contact sensor 27 exceeds a predetermined threshold value L (Figures 5 and 6), the discharge means 30 removes the parts 14 from the linear transport path 25.

The detection means in this embodiment is a magnetic induction type non-contact sensor 27 that detects changes in impedance as the metal part 14 moves in contact with or away from the sensor. Because the part 14 is a thin steel plate, as the part 14 moves along the linear conveying path 25, the part 14 approaches the magnetic induction type non-contact sensor 27, passes nearby, and then moves away. As the part 14 moves in contact with or away from the sensor, the detection output of the magnetic induction type non-contact sensor 27 changes.

That is, as shown in Figure 5(a), when the part 14 moves along the linear transport path 25 and approaches the magnetic induction type non-contact sensor 27, its detection output, i.e., the value of the detected impedance, increases, and as shown in Figure 5(b), it reaches a maximum value when the part 14 passes the magnetic induction type non-contact sensor 27, and as shown in Figure 5(c), when the part 14 moves away from the magnetic induction type non-contact sensor 27, its detection output decreases.

The value detected by this magnetic induction non-contact sensor 27 is the change in impedance that accompanies the contact and separation of the part 14, so as long as the part 14 is made of a conductive material, it will not change depending on whether or not the vibrating conveyor 24 is vibrating. Therefore, when a part 14 passes through, this fact can be reliably detected.

On the other hand, this magnetic induction type non-contact sensor 27 detects magnetic loss due to eddy currents that occur on the surface of conductive parts 14 due to the influence of the magnetic field generated by a detection coil (not shown) required for electromagnetic induction. Therefore, as shown in Figure 6, when parts 14 made of conductive material overlap, the detected impedance also increases.

That is, as shown in Figure 6(a), when multiple overlapping parts 14 move along the linear transport path 25 and approach the magnetic induction type non-contact sensor 27, the impedance value detected by the magnetic induction type non-contact sensor 27 is larger than when a single moving part 14 approaches without overlapping.

As shown in Figure 6(b), the detection output will reach a maximum value when the part 14 passes the magnetic induction non-contact sensor 27, but even this maximum value is larger than the maximum value that occurs when a single, non-overlapping part 14 passes by, and as shown in Figure 6(c), when the part 14 then moves away from the magnetic induction non-contact sensor 27, the detection output will decrease.

As shown in Figure 5, the detection output does not reach this threshold when a single, non-overlapping part 14 passes by, but as shown in Figure 6, the detection output detected when multiple overlapping parts 14 move along the linear conveying path 25 and approach and pass by the magnetic induction non-contact sensor 27 is exceeded by a predetermined threshold L. When the detection output of the magnetic induction non-contact sensor 27 exceeds this threshold L, the ejection means 30 is driven to remove the part 14 from the linear conveying path 25.

That is, this threshold value L is stored in the memory 31a of the controller 31, and the controller 31 compares the detection output of the magnetic induction type non-contact sensor 27 with this threshold value L, and activates the removal means 30 when the detection output exceeds this predetermined threshold value L. Therefore, as shown in Figure 5(c), when a single part 14 passes, the detection output of the magnetic induction type non-contact sensor 27 does not reach the predetermined threshold value L, so the removal means 30 is not activated, and the single part 14 continues to move along the linear conveying path 25 and be supplied, as shown in Figure 5(d).

On the other hand, when multiple parts 14 are being conveyed in an overlapping state and the detection output of the magnetic induction type non-contact sensor 27, which serves as the detection means, exceeds a predetermined threshold L, the controller 31 briefly opens the valve 34 to cause compressed air supplied from the compressor 32 via the air supply pipe 33 to be ejected from the blow-out hole 24b, as shown by the dashed line in Figure 4 and Figure 6(c), and blows away any parts 14 that have passed the magnetic induction type non-contact sensor 27 and are positioned so as to block the blow-out hole 24b, as shown by the solid arrow in Figure 4 and Figure 6(d), thereby removing the parts 14 from the linear conveyance path 25.

The return vibration parts feeder 40 in this parts alignment and supply device 9 operates simultaneously with the operation of the linear vibratory parts feeder 20, and as shown in Figure 4, parts 14 that fall off the linear conveying path 25 of the linear vibratory parts feeder 20 are received by the return conveying path 45 of the vibrating conveying body 44, and are returned to the bowl-type vibratory parts feeder 10 shown in Figure 1.

In this way, in the present invention, the state of the parts 14 is detected using a non-contact sensor 27 rather than the optical sensor that has been used conventionally, making it possible to detect overlapping of parts 14 with a high probability even if the thickness of the parts 14 to be detected is thinner than the vibration amplitude.

As a result, if the detection output exceeds a predetermined threshold L, indicating that parts 14 are overlapping, the ejection means 30 removes the parts 14 from the linear conveying path 25, thereby achieving the objective of the present invention of reliably preventing the supply of overlapping parts 14, even if the parts 14 are relatively thin.

Here, if the detection means is a magnetic induction type non-contact sensor 27 that detects changes in impedance, the change in impedance will increase even if the parts 14 moving along the linear conveyance path 25 are not overlapping but are moving very close to each other. For this reason, it is necessary to move multiple parts 14 sequentially along the linear conveyance path 25 of the vibrating conveyor 24 in the linear vibrating parts feeder 20, maintaining a spacing that does not affect the change in impedance detected by the magnetic induction type non-contact sensor 27.

However, this parts alignment and supply device 9 moves and loads parts 14 aligned by the bowl-type vibratory parts feeder 10 from its discharge outlet 11d onto the linear conveying path 25 of the linear vibratory parts feeder 20. By controlling the bowl-type vibratory parts feeder 10 to sequentially load multiple parts 14 onto the linear conveying path 25 of the linear vibratory parts feeder 20 while maintaining a predetermined distance between them, it is possible to prevent parts 14 from moving along the linear conveying path 25 in close proximity to each other.

In addition, this part alignment and supply device 9 is equipped with a return vibrating part feeder 40 that receives parts 14 removed from the linear conveying path 25 of the linear vibrating part feeder 20 and returns them to the bowl-type vibrating part feeder 10. Therefore, parts 14 removed from the linear conveying path 25 are resupplied from the bowl-type vibrating part feeder 10 to the linear vibrating part feeder 20, so the removed parts 14 are not wasted.

In the above-described embodiment, the blow-out hole 24b constituting the discharge means 30 is formed adjacent to the downstream side of the non-contact sensor 27, from which compressed air is blown out from the compressor 32. However, the discharge means 30 is not limited to compressed air, and may be a mechanical means of removal, as long as it can remove the parts 14 from the conveying path 25.

Even if compressed air is used, as long as the part 14 can be removed from the conveying path 25, the blow-out hole 24b may be formed near the non-contact sensor 27 or at a distance downstream rather than adjacent to it, and compressed air stored in an air tank may be blown out instead of from the compressor 32.
