BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply apparatus that transports components by injecting carrier air into a supply passage with a closed cross-section extending from a component supply source, receives the components with a supply head, and transports the components to a target location.

Japanese Patent Application Laid-Open No. 2007-136542 describes conveying parts by injecting conveying air into a supply passage having a closed cross section extending from a parts supply source. It also describes transferring the parts successively conveyed from the parts supply passage to a supply head provided on a reciprocating supply rod, and supplying the parts to the target location by advancing the supply rod.

JP 2007-136542 A

In the prior art described in Patent Document 1, the longitudinal direction of the component supply passage and the longitudinal direction of the retractable supply rod obliquely intersect, so it is difficult to make the entire device compact. . In addition, since there is no means for correctly maintaining the stop position of the parts transferred from the supply passage to the supply head, the stop position of the parts cannot always be fixed at a fixed normal position, and the standby position of the parts with respect to the target supply position of the parts is not provided. becomes inappropriate, and parts supply accuracy is not satisfactory.

When the parts are transferred to the supply head, it is sufficient if the parts stop at a predetermined position. Such misalignment may occur due to the magnetic force acting on the part due to the part being positioned in the magnetic field, or the part being rebounded from the stopper surface.

The positional deviation of the parts as described above is caused by the influence of a magnetic field or by some kind of vibration. is stopped.

Based on the above considerations, it is an object of the present invention to provide a compact device structure using a passage pipe as a main member, and to accurately maintain the movement trajectory of the parts and supply the parts with high accuracy.

The invention according to claim 1,
It is of a type that conveys parts by injecting carrier air into a supply passage formed in a passage pipe with a closed cross-section extending from a parts supply source,
A supply head formed with a groove for receiving a component is arranged in a continuous state with a passage member that constitutes the supply passage,
A stopper surface for setting a stop position of the part is formed at the end of the receiving groove,
an open passage is formed through which the conveyed air flows out from the receiving recessed groove to the outside;
When the airflow flowing out from the open passage hits the part, the part stopped at the abnormal position is pushed back to the stopper surface to maintain the normal position,
advance and retreat driving means for moving the parts held by the supply head to a target location is provided integrally with the passage pipe;
The advance direction of the parts in the supply passage and the advance direction of the supply head are the same,
advance/retreat movement means for displacing the passage pipe integrally with the supply head, the advance/retreat driving means, etc. to set the advance position of the supply head at a predetermined position;
In the component supply apparatus, the supply head is provided with a delivery drive means for delivering the component from the normal position of the supply head in a state in which the supply head is advanced to a predetermined position by the forward/backward drive means.

The long and narrow passage tube is used as a main member, and the advancing/retreating driving means for advancing and retreating the supply head is arranged integrally with the passage tube. The basic structure of is elongated, making it easier to put together into a compact shape. At the same time, it is advantageous to install the device in a narrow space.

Since the parts conveying direction in the supply passage, the conveying direction of the receiving concave groove of the supply head, and the advancing direction of the supply head due to the operation of the forward/backward driving means are all the same, the parts conveying behavior is simplified and the parts are supplied. reliability improvement can be achieved.

Conveying air for the part flows out from the receiving groove through an open passage leading to the outside, and the resulting air flow acts on the part, pushes the part back to the stopper surface, and allows the part to stand by at the normal position of the supply head. can. The parts coming into the receiving groove of the supply head from the supply passage hit the stopper surface and are stopped at a predetermined position. may stop. If the supply head is moved while the parts are stopped at such an abnormal position, the parts cannot be accurately supplied to the target location, resulting in defective supply.

The parts are pushed back by the airflow, continue to receive the airflow, stop at the normal position of the supply head, and are sent out from this normal position by the delivery driving means, so that the parts can be accurately supplied to the final supply destination. can.

Since the passage pipe is displaced integrally with the supply head, the advance/retreat driving means, etc. by the advance/retreat movement means, the related structures can be displaced as one piece, which is advantageous in terms of structural simplification. Further, for example, even when the movable electrode is positioned at the advance destination of the supply head, the supply head can be operated while avoiding the movable electrode.

A cover member is mounted in a state in which a gap is formed through which the conveying air that has flowed into the receiving groove can flow out. Alternatively, an open hole is formed in the cover member. Therefore, the conveying air forms an air flow passing through the gap or the open hole, whereby the air flow impinges on the part, and the part is moved to a position where it abuts against the stopper surface. Since the parts are moved to the correct positions in this way, the parts moved by the advance/retreat drive means can be accurately supplied to the target locations such as the electrode for electric resistance welding, and good parts supply can be ensured.

The part is stopped at the regular position by the stopper surface. A delivery driving means for delivering the parts is provided integrally with the supply head. Therefore, the passage pipe, the supply head, the forward/backward drive means for advancing the supply head, the delivery drive means for delivering the parts from the supply head, etc. can be formed as an integrated unit structure, and the overall apparatus can be made compact. It becomes possible. Since the whole unit structure can be displaced by the advancing/retreating means connected to the stationary member, the parts can be accurately supplied to the target location such as the electric resistance welding electrode. can.

It is the whole device and a sectional view of each part. FIG. 4 is a cross-sectional view of the supply head; FIG. 10 is a cross-sectional view showing a modification of the supply head;

Next, a mode for carrying out the component supply device of the present invention will be described.

1, 2 and 3 show an embodiment of the invention.

First, the parts will be explained.

Parts to be supplied in this embodiment include various parts such as washers and projection nuts. Here, the latter projection nut is targeted for supply. In the following description, the projection nut may be simply expressed as a nut.

The projection nut 1 is made of iron, and as shown in FIG. Since the welding projection 4 also protrudes in the diameter direction of the screw hole 3, the welding projection 4 abuts against a later-described stopper surface. As for the dimensions of each part of the nut 1, the vertical dimension of the body 2 is 12 mm, the thickness dimension of the body 2 is 6 mm, and the inner diameter dimension of the screw hole 2 is 6 mm.

Next, the supply passage will be explained.

This device 100 is a nut feeder. The parts feeder 5, which is a parts supply source, is of a general type that imparts a feeding vibration to a bowl 6 in which the nuts 1 are stored. 8 is connected. The nut 1 is conveyed by blowing conveying air into the outlet pipe 7 from the injection pipe 9. - 特許庁The supply hose 8 is a passage member, and the inside thereof is a supply passage 8A.

A passage pipe 12 is connected to the supply hose 8 via a joint member 10 . The passage pipe 12 is made of metal such as stainless steel, and as shown in FIG. . Therefore, the passage pipe 12 is a passage member, and the inside thereof serves as a supply passage 12A. The supply passage 8A of the supply hose 8 and the supply passage 12A of the passage pipe 12 have a rectangular cross-sectional shape so that the nut 1 can be passed through without being reversed in the front and back direction, and both passages 8A and 12A communicate smoothly. there is

In addition, although the injection pipe 9 is attached to the outlet pipe 7 to blow the carrier air, the groove member 13 may be provided with an injection port to blow in the direction of the arrow 40 shown in FIG. 1(A). .

Next, the supply head will be explained.

A supply head 15 is arranged so as to be continuous with the end of the groove member 13 . The supply head 15 is formed with a receiving recessed groove 16 that is continuous with the recessed groove (supply passage 12A) of the groove member 13. One end communicates with the supply passage 12A, and the inner end surface of the other end extends in a substantially vertical direction. A standing stopper surface 17 is provided.

As shown in FIG. 1A, the cover plate 14 protrudes like a canopy so as to cover the supply head 15, and this protruding portion is the cover member 18. As shown in FIG. A gap 21 is formed between the upper surface 19 of the supply head 15 and the lower surface 20 of the cover member 18 . This gap 21 is an open passage through which air flows out, and is given the same reference numeral 21 .

As shown in FIG. 2, the welding projection 4 abuts against the stopper surface 17, so that the correct stop position of the nut 1 on the supply head 15 is set. A permanent magnet 22 is embedded in the end of the delivery head 15 to maintain this position. The position where the welding projection 4 of the nut 1 is received by the stopper surface 17 is the normal position, and a sensor 24 for detecting this position is fixed to the cover member 18 . A suitable sensor 24 is one that magnetically detects the nut. When the nut 1 stops at the abnormal position indicated by the two-dot chain line in FIG.

Next, the target location of nut supply will be described.

There are various locations to which the nut 1 is delivered, that is, target locations. There are places corresponding to electric resistance welding electrodes and places where bolts are waiting. Here, the former electric resistance welding electrode is used.

A fixed electrode 25 is arranged coaxially with the electrode axis OO arranged in the vertical direction, and a steel plate component 26 is placed thereon. A positioning pin 27 provided at the center of the fixed electrode 25 passes through a pilot hole 28 of the steel plate component 26 relatively. A movable electrode 29 is arranged vertically coaxially with the fixed electrode 25 .

A concave hole 30 into which the nut 1 is fitted is formed in the central portion of the lower end surface of the movable electrode 29 . The recessed hole 30 is circular, and the diameter of the recessed hole 30 is the dimension slightly longer than the diagonal line of the main body 2 of the square nut 1 . A permanent magnet 31 embedded in the movable electrode 29 is arranged near the recessed hole 30 .

Next, the advancing/retreating driving means will be explained.

The nut 1 is supplied to the target location as described above by moving the supply head 15 . For this purpose, the supply head 15 is moved back and forth by the back and forth driving means. As the advance/retreat drive means, various devices such as an advance/retreat output type electric motor and an air cylinder can be employed. The air cylinder 33 is fixed to the lower surface of the groove member 13 by bolting or the like, and the forward/backward direction of the piston rod 35 is the same as the longitudinal direction of the supply passage 12A. A connecting piece 34 is fixed to the lower surface of the supply head 15 , and a piston rod 35 of the air cylinder 33 is fixed to the connecting piece 34 .

The receiving groove 16 of the supply head 15 is arranged on the longitudinal extension of the supply passage 12A so as to communicate with the supply passage 12A. parallel. Due to this positional relationship, the nut 1 is delivered by the supply head 15 in the same direction as its entering direction.

Next, the stop-passing unit will be explained.

When a strong air flow is injected from the injection pipe 9 into the supply passage 8A, the nut 1 passes through the supply passage 12A at high speed and collides with the stopper surface 17 of the supply head 15. - 特許庁If such collisions are repeated, the welding projection 4 may bite into the stopper surface 17, and the nut 1 may not be smoothly delivered from the receiving recessed groove 16.

Therefore, the stop-passing unit 36 is employed. A stopper member 37 protrudes into the supply passage 12A from the stop-passing unit 36 to temporarily stop the nut 1 advancing at high speed. Sent. Normally, the length of the supply hose 8 is 2 to 4 m, so the high-speed air flow from the injection pipe 9 has a low velocity near the supply passage 12A. It collides with the stopper member 37 without lowering. When the stopper member 37 is retracted, the nut 1 is fed to the feed head 15 at low speed by the reduced airflow.

As means for moving the stopper member 37 back and forth, various means such as an electromagnetic solenoid, a back and forth output type electric motor, and an air cylinder can be used. An air cylinder 38 is employed here, the piston rod 39 of which extends into and out of the supply passage 12A.

As shown in FIG. 1(A), it is also possible to form an oblique air injection port in the bottom member of the groove member 13 and to inject air from the direction of the arrow 40 to assist the movement of the nut.

A sensor 42 is provided to detect that the nut 1 is waiting when the second nut 1 is stopped by the stopper member 37 .

Next, the advancing/retreating means will be described.

The arrangement positions of the fixed electrode 25 and the movable electrode 29 are shifted from the supply head 15 in relation to peripheral related equipment such as a robot device (not shown) for inserting the steel plate component 26 . When the most retreated supply head 15 advances rightward, the tip of the supply head 15 interferes with the movable electrode 29 . Therefore, when the supply head 15 is lowered by the height H from the position before advancing, the supply head 15 is advanced, as shown in FIG. As with the position of the delivery head 15 after the advance, the above interference is avoided. In order to perform such avoidance, a forward/backward movement means is provided.

As the advance/retreat movement means, various devices such as an advance/retreat output type electric motor and an air cylinder can be employed. Since the passage tube 12 is displaced integrally with the supply head 15 and the air cylinder 33, which is the advancing/retreating driving means, by the advancing/retreating means, that is, the air cylinder 43, the related structures are displaced as one piece.

In order to realize the one-piece construction of the above-mentioned related structures, as shown in FIG. , the piston rod 44 of which advances and retreats substantially vertically. A connecting piece 45 is welded to the lateral side of the passage tube 12, to which the piston rod 44 is connected.

The supply head 15 is integrated with the passage tube 12 and the air cylinder 33 and lowered by the height H due to the movement of the forward/backward movement means, that is, the air cylinder 43 . Then, the air cylinder 33 is operated to advance the supply head. In this advance, the supply head 15 and the nut 1 correctly enter between the two electrodes 25 and 29 without interfering with the movable electrode 29 . Incidentally, when the passage pipe 12 moves up and down, the supply hose 8 is elastically deformed by an amount corresponding to the height H, and follows the movement.

An air cylinder 43 is rigidly connected to the stationary member 11, its piston rod 44 is connected to the passage pipe 12 via a connecting piece 45, the air cylinder 33 is fixed to the lower side of the passage pipe 12, and the supply Head 15 is also connected to piston rod 35 of air cylinder 33 . Further, a delivery drive means, which will be described later, is also coupled to the supply head 15 . The arrangement position of the entire device 100 is set by connecting the air cylinder 43 to the stationary member 11 .

Next, the delivery driving means will be explained.

As the delivery drive means, various devices such as forward/backward output type electric motors and air cylinders can be employed. The feeding drive means feeds the nut 1 from the normal position of the feeding head 15 toward the final feeding position in a state where the feeding head 15 is advanced to a predetermined position by the air cylinder 33 . A connecting piece 47 is welded to the tip of the supply head 15 while extending downward. An air cylinder 46 is fixed to a connecting piece 47 by bolting or the like, and its piston rod serves as a delivery rod 48 . The mounting posture of the air cylinder 46 is set so that the delivery rod 48 advances and retreats in the vertical direction.

A through hole 49 (see FIGS. 2 and 3) is formed in the bottom member of the supply head 15 so that the threaded hole 3 of the nut 1 stopped at the normal position and the delivery rod 48 are positioned on the electrode axis OO. ing.

Next, the abnormal displacement of the nut will be explained.

For various reasons, the nut 1 that has entered the receiving groove 16 of the supply head 15 may be displaced to the position indicated by the chain double-dashed line in FIG. One of the factors is that when a welding current is passed from the movable electrode 29 toward the fixed electrode 25, if the nut 1 is present in the magnetic field generated by this current flow, the force in the direction away from the electrode axis OO is generated. acts on the nut 1, the force exceeds the attractive force of the permanent magnet 22, and the nut 1 is displaced. Furthermore, as another factor, when a steel plate component or the like being carried by an operator collides with the groove member 13, the nut 1 is displaced due to the impact.

Next, the air flow will be explained.

The carrier air blown from the injection pipe 9 reaches the supply head 15 through the supply passage 8A and the supply passage 12A, which have a closed cross section structure. A gap or open passage 21 is formed between the upper surface 19 of the supply head 15 and the lower surface 20 of the cover member 18 protruding upward from the supply head 15 . This gap 21 opens at the end of a series of air circulation passages such as the injection pipe 9, the supply passage 8A and the supply passage 12A. Therefore, the air flow from the injection pipe 9 continues without interruption until it reaches the receiving recessed groove 16 of the supply head 15, although the flow velocity decreases. Since such an air flow hits the nut 1, the nut 1 temporarily separated from the stopper surface 17 (indicated by the two-dot chain line in FIG. 2) is returned to the stopper surface 17 again to correct the positional deviation.

Next, a modified example of the open passage will be described.

This modification has an open hole 50 in the cover member 18 instead of the air gap 21 as described above. Therefore, when the piston rod 35 advances and retreats, the lower surface 20 of the cover member 18 and the upper surface 19 of the supply head 15 are in a sliding state, or the gap between the two surfaces 20 and 19 is minute. The airflow flows out from the open hole 50, and the positional deviation correction operation is performed with the same wind pressure as in the case described above. The rest of the configuration is the same as in FIGS. 1 and 2, including parts not shown, and members with similar functions are denoted by the same reference numerals.

Next, the operating sequence of the device will be described.

FIG. 1(A) shows a state in which the supply head 15 is at the most retracted position due to the return operation of the air cylinder 33 and the nut 1 is stopped at the normal position by the permanent magnet 22. FIG. Also, the stopper member 37 of the stop-passing unit 36 advances to temporarily stop the nut 1 transferred at high speed. The existence of the nut 1 stopped at the normal position of the supply head 15 is detected by the sensor 24 . On the other hand, the presence of the temporarily stopped nut 1 is detected by the sensor 42 .

Detection signals from both sensors 24 and 42 are subjected to AND processing, which becomes a trigger signal, and the air cylinder 43 moves downward by the height H this time. After that, the supply head 15 advances to the right by the advancing operation of the air cylinder 33, and the tip of the supply head 15 enters between the movable electrode 29 and the fixed electrode 25 without interfering with the movable electrode 29, and the nut 1 is coaxial with the electrode axis OO.

Next, the delivery rod 48 is raised by the delivery operation of the air cylinder 46, and the nut 1 is delivered against the attraction force of the permanent magnet 22 and inserted into the recessed hole 30. At this time, the attraction force of the permanent magnet 31 is applied. Even if the nut 1 is acted on and the delivery rod 48 is retracted, the nut 1 is held by the movable electrode 29 without falling. After the feed rod 48 is retracted, the supply head 15, the air cylinder 46, and the like are retracted from between the electrodes 25 and 29 by the retracting operation of the air cylinder 33 to prepare for receiving the next nut. Following this, the movable electrode 29 advances to press the nut 1 against the steel plate component 26, the welding current is applied, and the welding of the nut to the steel plate component 26 is completed. After the air cylinder 33 moves backward, the air cylinder 43 moves upward to return to its original state.

The advance timing of the delivery rod 48 can be advanced before the supply head 15 advances, and the advance rod 48 can be inserted into the screw hole 3 . The delivery rod 48 is formed with a small-diameter portion that enters the screw hole 3 and a large-diameter portion that has a larger diameter than the small-diameter portion. ) hits the lower surface of the nut 1 and raises the nut 1 to reach the recessed hole 30 .

In the above embodiment, the cover plate 14 is extended as it is to form the cover member 18 , but the cover member 18 may be prepared as a separate part and welded to the end of the groove member 13 .

It should be noted that, instead of the various air cylinders described above, it is also possible to adopt an electric motor that outputs forward/backward movements. It is also possible to replace the various permanent magnets described above with electromagnets.

The parts feeder is of a type that vibrates a bowl, but it may be of a type that attracts parts to a rotary plate with a magnet and feeds them out from a delivery pipe.

Operations such as forward/backward movement of each air cylinder and air injection can be easily performed by commonly employed control methods. Predetermined operation can be ensured by combining an air switching valve that operates with a signal from a control device or a sequence circuit, or a sensor that emits a signal at a predetermined position of the air cylinder and transmits it to the control device.

The effects of the embodiment described above are as follows.

A state in which the elongated passage tube 12 is used as a main member, and an advancing/retreating driving means for advancing and retreating the supply head, that is, an air cylinder 33 is integrally arranged with the passage tube 12, and the passage tube 12 and the supply head 15 are integrated. Therefore, the basic structure of the device 100 can be easily arranged in an elongated and compact shape. At the same time, it is advantageous to install the device 100 in a narrow space.

Since the feeding direction of the nut 1 in the supply passages 8A and 12A, the feeding direction of the receiving recessed groove 16 of the feeding head 15, and the advancing direction of the feeding head by the operation of the air cylinder 33, which is the advancing/retreating driving means, are all the same, the nut The transport behavior of 1 is simplified, and improved reliability of component supply can be achieved.

Conveying air for the projection nut 1 flows out from the receiving recessed groove 16 through open passages such as the gap 21 and the open hole 50 leading to the outside, and the air flow caused by this flows to the nut 1, causing the nut 1 to move to the stopper surface 17. By pushing back, the nut 1 can be made to stand by at the normal position of the supply head 15 . The nut 1 entering the receiving groove 16 of the supply head 15 from the supply passages 8A and 12A hits the stopper surface 17 and stops at a predetermined position. may stop at a location away from the stopper surface. If the supply head 15 is moved while the nut 1 is stopped at such an abnormal position, the nut 1 cannot be accurately supplied to the recessed hole 30, which is the target location, and a supply failure occurs.

The nut 1 is pushed back by the air flow, continues to receive the air flow, stops at the normal position of the supply head 15, and is sent out from this normal position by the air cylinder 46, which is the sending drive means, so that the nut 1 reaches the final supply destination ( It can be accurately fed to the recess 30). That is, by continuing the airflow to blow against the nut 1, the nut 1 is maintained in a state of abutting against the stopper surface 17, which is suitable as a nut standby state when the nut 1 is pushed out by the air cylinder 46.

The passage tube 12 is displaced integrally with the supply head 15, the advance/retreat driving means 33, etc. by the air cylinder 43, which is the advancing/retreating means, so that the related structures can be displaced as one piece, and the structure is simplified. It is advantageous in terms of Further, for example, even when the movable electrode 29 is positioned at the advance destination of the supply head 15, the supply head 15 can be operated while avoiding the movable electrode 29. FIG.

A cover member 18 is mounted with a gap 21 through which air flowing into the receiving groove 16 can flow out. Alternatively, an open hole 50 is formed in the cover member 18 . Therefore, the conveying air forms an air flow passing through the gap 21 and the open hole 50 , whereby the air flow hits the nut 1 and the nut 1 is moved to a position where it abuts against the stopper surface 17 . Since the nut 1 is moved to the correct position in this way, the nut 1 moved by the advancing/retreating driving means 33 is accurately supplied to the target location such as the recessed hole 30 of the electric resistance welding electrode, so that parts can be supplied satisfactorily. can be secured.

The nut 1 is stopped at the regular position by the stopper surface 17 . An air cylinder 46, which is a driving means for feeding the nut 1, is provided integrally with the supply head 15. As shown in FIG. Therefore, the passage pipe 12, the feed head 15, the air cylinder 33 for advancing the feed head 15, the air cylinder 46 for feeding the nut 1 from the feed head 15, etc., can be formed as an integral unit structure. 100 can be made compact. Since the entire unit structure as described above can be displaced by the air cylinder 43 coupled to the stationary member, the nut 1 can be accurately supplied to a target location such as an electric resistance welding electrode. can be done. In particular, it is suitable for moving the entire apparatus 100 depending on the movement trajectory of the robot apparatus for steel plate parts, the placement of the welding machine, and the like.

Since the sensor 24 attached to the cover member 18 emits a detection signal when the nut 1 is stopped at the proper position, this signal can be used as a trigger signal to advance the supply head 15. can be correctly supplied to the target location. Therefore, when the nut 1 is stopped at an abnormal position, no part detection signal is issued, so that the operation of the supply head 15 to the next stage can be prohibited, which is effective in preventing malfunction.

As described above, according to the apparatus of the present invention, the structure of the apparatus is made compact by using the passage pipe as a main member, and the movement trajectory of the parts is maintained correctly, so that the parts can be supplied with high precision. Therefore, it can be used in a wide range of industrial fields, such as automobile body welding processes and home electric appliance sheet metal welding processes.
