Description

  The present invention extracts a ring-shaped part from a workpiece supply mechanism that moves a workpiece support portion on which a workpiece is supported to an assembly position, and a component magazine that stores a plurality of ring-shaped components. The present invention relates to a component assembling apparatus having a component supplying mechanism for feeding and a component mounting mechanism for mounting the ring-shaped component on the workpiece at the assembly position.

  As prior art document information related to this type of component assembly apparatus, there is Patent Document 1 shown below. The component assembling apparatus described in Patent Document 1 is a line conveyor-like work conveying device that sequentially conveys a clamp with a workpiece attached to an assembling position, and ring components from the component feeder to the assembling position one by one. The supply device includes a supply pusher, a component pusher that is moved up and down by a hydraulic cylinder in order to externally attach the supplied ring-shaped component to the workpiece.

JP-A-64-34619 (2nd page, lower right column, 2nd line-3rd page, upper right column, 6th line, FIG. 1)

  However, since the component assembly apparatus described in Patent Document 1 uses mechanical drive means such as a hydraulic cylinder as means for moving the component pusher up and down, energy resources such as electric power must be consumed. there were. Moreover, since the component assembling apparatus same as the above requires a sturdy support structure for such mechanical drive means, the entire equipment tends to be enlarged.

  Further, Patent Document 1 does not describe any means for solving a case where a ring-shaped part is in a shortage state in the part supply unit of the apparatus or a work is in a shortage state in the work transport device. For this reason, there is a concern that a workpiece with no parts mounted is discharged, or that a ring-shaped part falls into the apparatus alone.

  An object of the present invention is to provide a component assembling apparatus that does not require the consumption of energy resources such as electric power, and at the same time requires a smaller overall equipment, in view of the drawbacks of the conventional component assembling apparatus exemplified above. It is to provide.

  Another object of the present invention is that even when a ring-shaped part or workpiece is in a shortage state, a workpiece with no parts attached is discharged, or the ring-shaped part falls into the apparatus alone. The object is to provide a component assembling apparatus that does not occur.

The first characteristic configuration of the component assembling apparatus according to the present invention is as follows.
A workpiece supply mechanism for moving a workpiece support portion capable of supporting a workpiece to an assembly position;
A component supply mechanism for extracting one ring-shaped component from a component magazine capable of storing a plurality of ring-shaped components and sending the extracted ring-shaped component to the assembly position;
A component mounting mechanism that mounts the ring-shaped component on the workpiece at the assembly position;
Based on an operation of displacing a single handle, movement of the workpiece support by the workpiece supply mechanism, feeding of the ring-shaped component by the component supply mechanism, and mounting of the ring-shaped component by the component mounting mechanism; And a motion conversion mechanism that completes the process.

  In the component assembling apparatus according to the first characteristic configuration of the present invention, the operation of moving the workpiece to the assembling position and the ring-shaped components one by one are sent to the assembling position one by one without using mechanical drive means such as a hydraulic cylinder The operation and the operation of mounting the ring-shaped part on the workpiece at the assembly position can be realized by a displacement operation by human power on a single handle. Therefore, it is not necessary to consume energy resources such as electric power. In addition, since the structure for supporting the mechanical driving means is not required, the entire equipment can be small.

  According to another characteristic configuration of the present invention, the motion conversion mechanism includes a first cam link mechanism that converts a displacement of the handle into a first linear motion for the workpiece supply mechanism and the component supply mechanism, and a displacement of the handle of the component mounting mechanism. And a second cam link mechanism for converting to a second linear motion that intersects the first linear motion.

  With this configuration, the operator simply moves the handle, and a part of the operating force is converted into the first linear motion by the first cam link mechanism to drive the workpiece supply mechanism and the component supply mechanism. The remaining part of the operation force is converted into the second linear motion by the second cam link mechanism, and the component mounting mechanism is driven.

In another aspect of the present invention, the first cam link mechanism includes a first link arm connected at one end to the workpiece supply mechanism and the component supply mechanism, a second link arm connected at one end to the component mounting mechanism, A cam member for guiding a connecting portion between the other ends of the first link arm and the second link arm along a fixed locus;
The cam member continuously includes a first cam surface that generates only the first linear motion while stopping the second linear motion, and a second cam surface that generates only the second linear motion while stopping the first linear motion. In preparation for
The handle is directly connected to a part of the first link arm.

  In this configuration, the first link arm is operated by a handle displacement operation by an operator. At this time, first, the connecting portion between the first link arm and the second link arm moves along the first cam surface. Therefore, the component mounting mechanism related to the second linear motion does not move, and only the workpiece supply mechanism and the component supply mechanism related to the first linear motion can be driven. Since the connecting portion next moves along the second cam surface, the work supply mechanism and the component supply mechanism related to the first linear motion do not move here, and only the component mounting mechanism related to the second linear motion is driven. be able to. For this reason, there is no possibility that the workpiece supply mechanism, the component supply mechanism, and the component mounting mechanism interfere with each other.

  In another feature of the present invention, the first cam surface is an arc centered on one end of the second link arm connected to the component mounting mechanism, and the second cam surface includes the workpiece supply mechanism and the component supply mechanism. It exists in the point which consists of a circular arc centering on the end of the connected 1st link arm.

  Accordingly, a configuration in which the workpiece supply mechanism and the component supply mechanism and the component mounting mechanism do not interfere with each other can be easily realized. That is, according to this configuration, while the connecting portion between the first link arm and the second link arm is moving on the first cam surface, the second link arm is swung along the first cam surface. However, the component mounting mechanism is not affected. Conversely, while the connecting portion is moving on the second cam surface, even if the first link arm is swung along the second cam surface, the workpiece supply mechanism and the component supply mechanism are not affected. . In this way, with this configuration, it is possible to obtain a component assembling apparatus having a simple configuration with little waste.

  Another characteristic configuration of the present invention is that a first regulating mechanism is provided in the workpiece supporting portion to regulate the operation of the workpiece supply mechanism when the workpiece is not available.

  With this configuration, when the workpiece is out of stock at the workpiece support portion, the operation of the workpiece supply mechanism is automatically restricted, and the assembling operation does not proceed. Therefore, there is no possibility that only the ring-shaped part will fall into the apparatus alone, and there is no possibility that the operator will use the operation handle unnecessarily.

  Another feature of the present invention is that a second restriction mechanism is provided for restricting the operation of the component supply mechanism when a ring-shaped component is not available in the component magazine.

  With this configuration, when a ring-shaped part is missing in the parts magazine, the operation of the part supply mechanism is automatically restricted, and the assembly operation does not proceed. Therefore, a workpiece with no ring-shaped part mounted can be obtained. Is prevented.

  In another aspect of the present invention, the component supply mechanism includes a component supply plate for feeding the ring-shaped component from the component magazine to the assembly position, and a component supply stage for supporting and guiding the ring-shaped component fed by the component supply plate. And a preceding arrival mechanism that causes the component supply stage to reach the assembly position prior to the supply of the ring-shaped component by the component supply plate.

  With this configuration, the component supply stage reaches the assembly position before the ring-shaped component is supplied to the assembly position. For this reason, even if there is a gap in which the ring-shaped component can fall before the assembly position, this gap is filled in advance by the component supply stage, and the ring-shaped component fed out by the component supply plate is There is no risk of falling inside.

  In another feature of the present invention, the component supply plate and the component supply stage immediately after supplying the ring-shaped component to the assembly position are retracted from the assembly position regardless of the position of the single handle. It is in a point including an immediate return mechanism.

  With this configuration, the component supply plate and the component supply stage are retracted from the assembly position immediately after completing the supply of the ring-shaped component to the assembly position. Therefore, even if a high-speed assembly process is performed by operating the handle at short intervals, there is no possibility that the component mounting mechanism interferes with the workpiece supply mechanism or the component supply mechanism and the apparatus breaks down.

  According to another feature of the present invention, as a finished product in which the ring-shaped component is mounted following the mounting of the ring-shaped component by the component mounting mechanism based on the operation of displacing the single handle. A payout mechanism for removing the work from the work support is provided.

  With this configuration, the workpiece as a completed product is automatically removed from the workpiece support portion while the handle is returned to the initial position, and the next workpiece can be attached to the workpiece support portion. Therefore, the worker can wait for the work support portion to be empty while holding the next work in his / her hand.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 9 includes an O-ring P (an example of a ring-shaped part) made of rubber or the like in an annular groove Wd formed near the upper end of a cylindrical cap W (an example of a work). It is an apparatus that performs an external fitting operation using only human power as power.
Hereinafter, for the sake of convenience, when the operator operates the component assembly apparatus 1, the side facing the operator is referred to as the front side of the component assembly apparatus 1, and an angle of 180 degrees with this front viewed from directly above. The back side forming the above is called the back side of the component assembling apparatus 1.

(Schematic configuration of component assembly equipment)
As shown in FIG. 1, the component assembling apparatus 1 includes a support base 2 having a flat lower surface, a pair of support columns 3 erected substantially vertically on the support base 2 at intervals, and a support base 2. And a multi-linkage mechanism 4 fixed to the head. The assembly position A where the O-ring P is attached to the cap W based on the operation of the operation handle H by the operator is set between the pair of columns 3. The upper ends of the pair of struts 3 are connected by a top plate 5 extending horizontally.
FIG. 2 is an operation explanatory view of the component assembling apparatus 1 viewed from the right side with respect to the configuration of each part of the component assembling apparatus 1 and the movement of each part executed in accordance with the displacement of the operation handle H. Description will be made with reference to FIG.

(Work support and parts set holder)
As shown in FIG. 2, a generally cylindrical work support 12 (work support part) for an operator to set a cap W as a work on the front side (left end part of FIG. 2) of the component assembling apparatus 1. Example) is arranged.
Near the center of the support base 2, a rod-shaped component holder 13 (an example of a component magazine) that allows an operator to load a large number of O-rings P (such as several tens) is extended vertically. Yes. The component holder 13 is locked so as to be vertically movable closer to the front side than the center of the top plate 5.

  In the vicinity of the upper end of the component holder 13, a stopper 13 s that is locked to the top plate 5 is provided. The component holder 13 is stopped by its own weight in a state where the stopper 13 s is in contact with the upper surface of the top plate 5. In this stationary state, a vertical component space that is slightly larger than the outer diameter of the O-ring P and can accommodate only one O-ring P between the upper surface of a component supply stage 16 described later and the lower end of the component holder 13. The position of the stopper 13s is adjusted so that S is formed.

  In addition, a cylindrical weight 14 that presses a large number of loaded O-rings P downward is externally installed on the component holder 13 so as to be slidable up and down. When the setting by the operator is completed, the lowermost O-ring P is always pressed against the upper surface of the component supply stage 16 by the pressing action of the cylindrical weight 14, as shown in FIG. It is placed in the component space S and is in a supply standby state released from the component holder 13.

(Schematic structure of multi-link mechanism)
The multi-linkage mechanism 4 includes a workpiece supply mechanism 6 that moves the cap W set on the workpiece support 12 at the preset position PP on the near side to the assembly position A at the back, and an O-ring P from the component holder 13. A component supply mechanism 7 that extracts and feeds them to the assembly position A one by one, a component mounting mechanism 8 that mounts the O-ring P to the cap W at the assembly position A, and a finished product cap W with the O-ring P mounted And a payout mechanism 9 for paying the workpiece from the workpiece support 12 to the near side.

  The operation handle H is provided on the right side of the component assembling apparatus 1 in a form that can be displaced up and down generally by human power. The operation handle H is operated by a simple action including a downward outward path and an upward backward path. Based on the displacement of the operation handle H due to this action, the workpiece supply mechanism 6, the component supply mechanism 7, the component mounting mechanism 8 and the dispensing mechanism 9 described above operate in association with each other, so that each cap W can be operated. The operation of mounting the O-ring P is continuously advanced.

The operation handle H is displaced by each operation of the workpiece supply mechanism 6, the component supply mechanism 7, the component mounting mechanism 8, and the dispensing mechanism 9 by the cam link mechanism 60 provided on the back side of the component assembly apparatus 1. Is converted to
The operation of attaching the O-ring P to the cap W is performed by a generally conical cone as an auxiliary jig for forcibly expanding the diameter of the O-ring P on the cap W attached to the work support 12 by the operator. This is performed with the jig C placed.

(Schematic flow of component mounting operation)
In order to facilitate understanding of the device structure, the flow of operations for mounting the O-ring P to the cap W by the component assembling device 1 will be briefly described before describing the detailed configuration.
(1) As shown in FIG. 2, the operator sets the O-ring P on the component holder 13 and the cap W on the work support 12 at the preset position.

(2) FIG. 3 shows a state in which the operator has started to push the operation handle H downward from the initial position. With this operation, the workpiece supply mechanism 6 starts to supply the cap W together with the component holder 13 from the preset position to the assembly position A (first linear movement in the forward path). At the same time, the component supply mechanism 7 removes the cap W from the component holder 13. Two O-rings P begin to be supplied to the assembly position A (outward path of the first linear motion). As shown in FIG. 4, when the displacement of the operation handle H further proceeds, the component holder 13 and the O-ring P reach the assembly position A.

(3) As shown in FIG. 5, when the operation handle H is further pushed downward, the cone jig C is moved to the cap W by a part of the component mounting mechanism 8 (the second linear movement in the forward path). Placed on top. Next, the O-ring P prepared at the assembly position A is dropped onto the outer periphery of the cone jig C, and the cone jig C is moved by the other part of the component mounting mechanism 8 (the second linear movement in the forward path). Is fixed.
(4) FIG. 6 shows a state in which the O-ring P dropped on the outer periphery of the cone jig C is mounted on the cap W by still another part of the component mounting mechanism 8.

(5) Next, when the operator loosens the force applied to the operation handle H, the operation handle H is pushed up to the initial position, and as shown in FIG. 7, each part of the component mounting mechanism 8 returns to the initial position. Thus, the fixation of the cone jig C is released (second linear movement on the return path), and the cone jig C is pulled up from above the cap W (second linear movement on the return path).

(6) When the operation handle H is further returned, the cap W completed by the work supply mechanism 6 is returned from the assembly position A to the preset position together with the work support 12 as shown in FIG. Finally, as shown in FIG. 9, the cap W is removed from the work support 12 by the dispensing mechanism 9 (first linear movement in the return path), and a series of assembly operations is completed.

(Workpiece supply mechanism configuration)
As shown in FIGS. 1 and 2, the workpiece supply mechanism 6 includes a lower rack member 17 supported so as to be slidable horizontally (first linear motion) in the front-rear direction with respect to the support base 2. The cylindrical workpiece support 12 described above is fixed to the upper surface of the lower rack member 17 near the front side end via a floating mechanism (not shown). As a specific configuration of the floating mechanism, for example, a connecting rod having a large-diameter portion in the vicinity of the front end extends forward from the lower rack member 17, and on the other hand, the large-diameter is formed below the work support 12. What is necessary is just to make the part into the form which provided the knuckle member which can be latched and accommodated so that rotation around the axial center of the said connection rod was possible.

  As shown in FIG. 2, when the operation handle H is at the initial position (top dead center), the workpiece support 12 is at the preset position PP on the near side as viewed from the operator. When the operator lowers the operation handle H from the initial position after setting the cap W on the work support 12, the work support 12 moves toward the assembly position A together with the lower rack member 17 as shown in FIG. And start moving. As shown in FIG. 9, when the operation handle H is returned to the initial position, the work support 12 returns to the preset position PP from the assembly position A together with the lower rack member 17. The interlocking mechanism between the operation handle H and the lower rack member 17 will be described later.

(Configuration of parts supply mechanism)
As shown in FIG. 3, the component supply mechanism 7 includes an upper rack member 18 supported so as to be slidable horizontally in the front-rear direction with respect to the support base 2, and an assembly position A in conjunction with the upper rack member 18. A component supply plate 15 that feeds the O-ring P in the supply standby state above the assembly position A below the component holder 13 by moving forward toward the side. As shown in FIG. 4, the O-ring P fed by the component supply plate 15 is supplied to a component holding surface 21p located near the lower end of an opening / closing arm 21 described later.

  The component supply mechanism 7 includes a component supply stage 16 that supports an O-ring P in a supply standby state below the component holder 13. As shown in FIG. 3, the component supply stage 16 is assembled in conjunction with the upper rack member 18 prior to the operation of moving the O-ring P by the component supply plate 15 by the action of the advance arrival mechanism 57 described later. Slide and move to the position A side. The component supply stage 16 temporarily eliminates the gap existing between the lower end of the open / close arm 21 and the component supply stage 16 by this sliding movement, so that the O-ring P sent out by the component supply plate 15 is removed. Prevents unnecessary drop by its own weight through the gap.

(Configuration of component mounting mechanism)
As shown in FIG. 5, the component mounting mechanism 8 performs an operation of placing the cone jig C on the upper surface of the cap W supplied to the assembly position A, and then the O-ring P fed by the component supply plate 15. A component preset mechanism 10 for performing an operation of dropping onto the cone jig C is provided. Further, as shown in FIG. 6, a component pressing mechanism 11 for pressing down the O-ring P fitted on the cone jig C to the lower end of the cone jig C and moving it to the annular groove Wd of the cap W is provided.

(Configuration of parts preset mechanism)
As shown in FIG. 10, the component preset mechanism 10 includes a first vertical motion plate 19 that is externally fitted and supported so as to be vertically movable (second linear motion) along the pair of support columns 3, and a first vertical motion. And a second vertical movement plate 20 supported below the plate 19. Based on the displacement of the operation handle H, the second vertical moving plate 20 is pushed down along the column 3. The aforementioned opening / closing arm 21 is swingably suspended from the front surface of the first vertical movement plate 19, and an opening / closing cam member 22 for opening / closing the opening / closing arm 21 is provided on the front surface of the second vertical movement plate 20. It is fixed. A space in which the open / close cam member 22 can be stored is formed between the left and right arms constituting the open / close arm 21.

A pair of chuck arms 21a for suspending and supporting the cone jig C is provided at the lower end of the open / close arm 21, and a component holding for receiving the supplied O-ring P is provided on the upper surface of the chuck arm 21a. Surface 21p is formed. The component holding surface 21p is also formed with a concave surface for preventing the O-ring P from shifting.
An auxiliary rod 19r extends upward from a part of the upper surface of the first vertical moving plate 19 and is inserted into the through hole of the top plate 5. A nut-like stopper 19s is positioned vertically near the upper end of the auxiliary rod 19r. Adjustably screwed. The bottom dead center of the first vertical moving plate 19 is determined by the stopper 19s coming into contact with the upper surface of the top plate 5. A pair of rod-like spacers 20r that are slidably fitted to the support column 3 and that can come into contact with the lower end of the first vertical moving plate 19 extend upward from near the left and right ends of the upper surface of the second vertical moving plate 20. I'm out.

  As shown in FIG. 10, when the operation handle H is in the initial position, the stopper 19 s of the auxiliary rod 19 r is spaced upward from the top plate 5. The bar-shaped spacer 20r of the second vertical moving plate 20 is applied to the lower surface of the first vertical moving plate 19 by the biasing force of the compression coil spring Sp1 fitted on the support column 3 so as to bias the second vertical moving plate 20 upward. It is pressed. The open / close arm 21 is held in a closed posture that leaves almost no gap between the both sides of the open / close cam member 22 and the open / close arm 21 by a closing coil spring Sp2 suspended between the left and right open / close arms.

  When the second vertical moving plate 20 is pushed down from the state of FIG. 10 based on the operation of the operation handle H, the open / close arm 21 is held in the closed posture by the open / close cam member 22 by the closed coil spring Sp2, and the first vertical The moving plate 19 is moved downward together with the moving plate 19. By this downward movement, the cone jig C suspended and supported by the chuck arm 21a of the open / close arm 21 is also moved downward.

  Subsequently, when the second vertical moving plate 20 is operated to move downward, the cone jig C is placed on the upper end of the cap W set in advance on the work support 12 as shown in FIG. 11 (FIG. 5). Also, the stopper 19s contacts the upper surface of the top plate 5 at the same timing as this placement.

  When the second vertical moving plate 20 is further moved downward, the first vertical moving plate 19 reaches the bottom dead center by the stopper 19s, and only the second vertical moving plate 20 is continuously moved downward. For this reason, as shown in FIG. 12, the opening / closing arm 21 is opened by a pair of inclined cam surfaces 22c formed on the lower surface of the opening / closing cam member 22 against the urging force of the closing coil spring Sp2.

For this purpose, an inclined operated cam surface 21 c that receives the inclined cam surface 22 c is also formed on the inner surface side of the opening / closing arm 21.
When the opening / closing arm 21 is opened, the chuck arm 21a is separated from the cone jig C to the left and right, and at the same time, the O-ring P falls by its own weight from the component holding surface 21p of the chuck arm 21a. Locked to the neck.

(Configuration of the part pressing mechanism)
As shown in FIGS. 2 and 13, the component pressing mechanism 11 is inserted through a through hole formed in each central portion of the top plate 5, the first vertical moving plate 19, and the second vertical moving plate 20, and the lower end is the first one. 2 A jig fixing rod 24 extending downward from the vertical movement plate 20 and a component pusher 27 fixed to the lower surface of the second vertical movement plate 20 so as to be fitted around the jig fixation rod 24.

  As shown in FIG. 2, a large-diameter flange portion 24 f is provided near the center in the longitudinal direction of the jig fixing rod 24. A coil spring-like rod biasing spring Sp3 for biasing the flange portion 24f toward the upper surface of the second vertical moving plate 20 is provided at a portion of the jig fixing rod 24 located between the flange portion 24f and the top plate 5. The outer fitting is arranged.

  As shown in FIG. 2, when the second vertical moving plate 20 is located at the top dead center, the flange portion 24f is pressed against the upper surface of the second vertical moving plate 20 by the rod biasing spring Sp3. When the second vertical moving plate 20 is pushed down from the state shown in FIG. 2 based on the operation of the operation handle H, the jig fixing rod 24 is lowered integrally with the second vertical moving plate 20, as shown in FIG. As described above, the tip of the jig fixing rod 24 contacts the upper end of the cone jig C placed on the upper end of the cap W on the workpiece support 12. When the second vertical moving plate 20 is further pushed down, the second vertical moving plate 20 is separated downward from the flange portion 24f. However, as shown in FIG. 6, the jig fixing rod 24 is controlled by the rod biasing spring Sp3. The tool C is held while being pressed against the upper end of the cap W.

  As shown in FIG. 13, the component pusher 27 includes a cylindrical base end portion 27a fixed to the lower surface of the second vertical moving plate 20, and a cylindrical operation portion that extends downward from the lower end of the base end portion 27a. 27b is made of a resin member integrally provided. The operation unit 27b is divided into about 4 to 10 sections by a plurality of slits 27s extending vertically from the vicinity of the upper end to the lower end thereof. Based on the elasticity of the material constituting the component pusher 27, each of these sections is individually swingable in the radial direction. An annular groove 27d is formed on the outer periphery in the vicinity of the lower end of the operation portion 27b, and an O-ring 28 for energizing the lower end side of the operation portion 27b in the diameter reducing direction is engaged with the groove 27d. Yes.

In the initial state of being released from the external force, the inner diameter of the operation portion 27b is substantially equal to the outer diameter of the jig fixing rod 24 by the urging force of the O-ring 28 and is locked to the conical surface of the cone jig C. It is sufficiently smaller than the outer diameter of the O-ring P.
Therefore, when the component pusher 27 descends together with the second vertical moving plate 20, the lower end surface of each section of the operation portion 27b securely locks the O-ring P on the cone jig C, and the cone jig C It is pushed down along the outer circumferential surface of the cone. As shown in FIG. 6, the lower end of the operation portion 27 b gradually expands against the urging force of the O-ring 28 by this push-down operation, and the diameter of the O-ring P is simultaneously expanded.
When the O-ring P on the cone jig C crosses the lower end of the cone jig C downward, the O-ring P is fitted on the annular groove Wd of the cap W.

As shown in FIG. 13, a neck portion Cn for receiving reliable suspension support by the chuck portion 21a of the open / close arm 21 is formed at the upper end of the cone jig C, and is adjacent to the upper portion of the neck portion Cn. An engaging recess Cv for receiving the lower end of the jig fixing rod 24 is formed at the upper end of the enlarged diameter portion Cf.
A shallow fitting recess Cp that receives the vicinity of the upper end of the cap W is formed on the lower surface of the cone jig C.

(Structure of payout mechanism)
As shown in FIGS. 2 and 14, the payout mechanism 9 is based on the operation of the operation handle H, and similarly to the work support 12, the discharge member 29 that moves back and forth together with the lower rack member 17 and the lower rack member 17. A discharge cam unit 30 that moves the discharge member 29 up and down in accordance with the back-and-forth movement.

  As shown in FIG. 14, the discharge member 29 includes an upper discharge head 29h having a circular outer shape in plan view, a lower cam portion 29c having a rectangular outer shape in plan view, and a discharge head 29h and a cam portion 29c. Has a connection portion 29j for connecting the two. The discharge head 29h is interposed on the inner surface of the cylindrical workpiece support 12 so as to be slidable in the vertical direction. The cam portion 29 c is positioned below the work support 12 and creates a vertical movement of the discharge member 29 described later in cooperation with the discharge cam unit 30.

  As shown in FIG. 15, the discharge cam unit 30 biases the cam forming member 31 to a position closer to the center portion, and a pair of cam forming members 31 that are displaceable with a length of about several millimeters to the left and right. And a pair of coil springs Sp4. The cam forming member 31 is generally plate-shaped, and is supported by the support base 2 via a guide bar 33 extending laterally from the outer side surface of the cam forming member 31.

  As shown in FIG. 14, a generally triangular raised portion 31 </ b> B is formed on the inner side surface of the cam forming member 31 so that the front side is higher and the back side is lower. The front lower portion of the raised portion 31B is a first cam surface 31a that gradually protrudes inward from the front end to the rear. The inclined long side edge of the raised portion 31B is a second cam surface 31b that gradually increases from the back toward the front. When the workpiece support 12 is at the preset position PP, the cam portion 29c of the discharge member 29 is located at an initial position ahead of the first cam surface 31a.

  When the discharge member 29 moves rearward from the preset position PP shown in FIG. 2 and FIG. 15A in accordance with the operation in which the workpiece support 12 supplies the workpiece W to the assembly position A, the cam of the discharge member 29 As shown in FIG. 3 and FIG. 15B, the portion 29c moves while the cam forming member 31 is evenly spread left and right against the urging force of the coil spring Sp4. As shown in FIG. 15C, before the workpiece support 12 reaches the assembly position A, the cam portion 29c of the discharge member 29 is temporarily separated from the raised portion 31B, so that the cam forming member 31 is attached to the coil spring Sp4. Return to the initial state of close proximity to each other by the force.

  When the mounting of the O-ring P to the workpiece W is completed and the workpiece support 12 starts moving from the assembly position A to the near side, as shown in FIG. 8 and FIG. Since the cam portion 29c of the member 29 advances along the second cam surface 31b, the discharge member 29 is lifted. Based on this upward movement of the discharge member 29, the discharge head 29h of the discharge member 29 discharges the workpiece W from the workpiece support 12, as shown in FIG.

When the discharge member 29 returns to the preset position PP, the discharge member 29 also falls by its own weight from the front end of the second cam surface 31b and automatically returns to the initial position ahead of the first cam surface 31a. It is.
The cap W is disposed at the upper front side of the support base 2 because the cap W is discharged from the work head support 12 moving toward the front side to the front side rather than directly above by the discharge head 29h. It is received in the tray part T.

(Composition of cam link mechanism)
The cam link mechanism 60 that converts the displacement operation of the operation handle H by the operator into the operations of the workpiece supply mechanism 6, the component supply mechanism 7, the component mounting mechanism 8, and the payout mechanism 9 will be described below.
As shown in FIGS. 1 and 2, a first housing Bf that slidably houses and supports the front portion of the above-described lower rack member 17 having the work support 12 is provided near the center of the support base 2. It has been. As shown in FIG. 1, a second housing Br is provided behind the first housing Bf to house and support the rear portion of the lower rack member 17 and the upper rack member 18 so as to be slidable in the horizontal front-rear direction. ing. As shown in FIG. 2, the second housing Br has a pinion gear 34 that converts the forward movement of the upper rack member 18 into the rearward movement of the lower rack member 17, and the lower rack member 17 and the upper rack member 18. Is rotatably supported so as to operate in synchronism with.

  As shown in FIG. 2, the cam link mechanism 60 is swingably connected to the vicinity of the rear end of the upper rack member 18 via a lateral shaft 40 and extends generally forward, A second link arm 36 that connects the first link arm 35 and the second vertical moving plate 20 supported by the column 3 is provided. An input arm 35A is fixed to an intermediate portion of the first link arm 35 and extends generally obliquely upward. The operation handle H is installed sideways at the front end of the input arm 35A. Furthermore, the cam link mechanism 60 is provided as a cam follower and a guide roller 37 that is externally supported so as to be able to roll with respect to a shaft member that connects the front end of the first link arm 35 and the lower end of the second link arm 36. In addition, a cam plate member 50 fixed to the side surface of the second housing Br in order to define the movement trajectory of the guide roller 37 is included.

  The cam plate member 50 is formed with a first cam surface 50a and a second cam surface 50b having different extending directions. The first cam surface 50a generally includes an inclined surface that descends toward the front side, and the second cam surface 50b generally includes an inclined surface that descends toward the rear side. As a result, the lower end of the first cam surface 50a and the second The upper end of the cam surface 50b is connected so as to cross each other substantially perpendicularly. When the operation handle H is in the initial position, the guide roller 37 is located near the upper end (and at the same time, near the rear end) of the first cam surface 50a.

  The first link arm 35 and the first cam surface 50a constitute a “first cam link mechanism”, and the second link arm 36 and the second cam surface 50b constitute a “second cam link mechanism”. The first cam surface 50 a and the second cam surface 50 b provide the following action to the first link arm 35 and the second link arm 36 via the guide roller 37.

  In the downward (outward) operating force that the operating handle H follows by human power, the guide roller 37 rolls forward on the first cam surface 50a, so the first link connected to the vicinity of the rear end of the upper rack member 18. The arm 35 is moved forward with respect to the second casing Br while swinging somewhat downward. Therefore, this operating force is converted into a horizontal movement in the forward direction of the upper rack member 18, and at the same time, a horizontal movement in the backward direction of the lower rack member 17 is generated by the pinion gear 34.

  This rearward horizontal movement of the lower rack member 17 realizes the supply of the workpiece W to the assembly position A (the workpiece supply mechanism 6) until the guide roller 37 reaches the lower end of the first cam surface 50a. At the same time, the forward movement of the upper rack member 18 realizes the cutting out of the O-ring P and the supply to the assembly position A (part supply mechanism 7).

  The cross-sectional shape of the first cam surface 50a is a circle around the pivot axis X1 between the second vertical motion plate 20 and the second link arm 36 when the second vertical motion plate 20 is at the top dead center. It is comprised by the circular arc which consists of a part. Therefore, there is no possibility that the second vertical moving plate 20 is moved up and down by the second link arm 36 while the guide roller 37 moves upward or downward on the first cam surface 50a. Further, since the arc of the first cam surface 50a as a whole consists of a slope inclined from the rear upper side to the front lower side, the guide roller 37 can be moved with a relatively weak force via the operation handle H. When operating the operation handle H, it is difficult to generate a force that causes the component assembly apparatus 1 to move laterally.

  With the later operation force that the operation handle H follows by the human power downward (outward), the guide roller 37 rolls down the second cam surface 50b downward, so that the second connected to the second vertical moving plate 20 The link arm 36 is pulled down generally downward with respect to the support base 2, and the operation force is converted into a downward movement of the second vertical moving plate 20.

  The downward movement of the second vertical moving plate 20 is performed by placing the cone jig C on the supplied cap W and the jig fixing rod until the guide roller 37 reaches the lower end of the second cam surface 50b. 24, fixing the cone jig C and dropping the O-ring P onto the cone jig C (part preset mechanism 10), and using the part pusher 27, the O-ring P is moved from the cone jig C to the annular groove of the cap W. An operation for moving to Wd (part pressing mechanism 11) is realized.

  The cross-sectional shape of the second cam surface 50b is such that the upper rack member 18 in a state where the forward movement of the upper rack member 18 is completed and the forward displacement of the operation shaft member 61 with respect to the second housing Br is restricted by the stopper. It consists of a circular arc which consists of a part of circle | round | yen centering on the pivotal axis (axis center of the horizontal shaft 40) of the rear end of the member 18, and the 1st link arm 35. As shown in FIG. Therefore, there is no possibility that the upper rack member 18 is moved back and forth by the first link arm 35 while the guide roller 37 moves upward or downward on the second cam surface 50b. Further, since the arc of the second cam surface 50b as a whole consists of a slope inclined from the front upper side to the rear lower side, the guide roller 37 can be moved with a relatively weak force via the operation handle H. When operating the operation handle H, it is difficult to generate a force that causes the component assembly apparatus 1 to move laterally.

Under the upward (double-pass) operating force that the operating handle H follows by human power, the guide roller 37 rolls upward on the second cam surface 50b, so that the second link arm 36 generally moves relative to the support base 2. Pulled upward, the same operating force is converted into upward movement of the second vertical moving plate 20.
The upward movement of the second vertical moving plate 20 causes the component pusher 27 and the jig fixing rod 24 to be sequentially separated from the cone jig C until the guide roller 37 reaches the lower end of the second cam surface 50b. The operation of separating the cone jig C from the cap W is realized.

  Finally, with an upward (multi-path) late operation force that the operation handle H follows by human power, the guide roller 37 moves up the first cam surface 50a rearward, so that the first link arm 35 swings somewhat upward. The moving operation is performed backward with respect to the second housing Br while moving. Therefore, this operating force is converted into a horizontal movement of the upper rack member 18 in the rearward direction, and at the same time, a horizontal movement of the lower rack member 17 in the frontward direction is generated.

  The rearward movement of the upper rack member 18 causes the component supply plate 15 and the component supply stage 16 to return to their respective rear initial positions until the guide roller 37 reaches the lower end of the first cam surface 50a. At the same time, the forward movement of the lower rack member 17 realizes the return of the work support 12 and the work W to the assembly position A (work supply mechanism 6), and in the vicinity of the final stage of the return. Thus, the discharge of the workpiece W to the tray portion T by the dispensing mechanism 9 is realized.

  As shown in FIG. 2, a spring support arm 41 extending from the vicinity of the rear end portion of the first link arm 35 to the rear and upward is fixed near the rear end of the second casing Br. A tension coil spring Sp6 that assists the return of the input arm 35A and the operation handle H to the initial positions is suspended between the upper end portion of 41 and the vicinity of the rear end portion of the first link arm 35. Further, a lightening recess (not shown) for lightening is formed on the side surface of the input arm 35A provided with the operation handle H, and this also moves upward (returns) to the initial position of the input arm 35A. Has been made easier.

(Configuration of the first restriction mechanism)
As shown in FIG. 16, the component assembly device 1 supplies the workpiece when the operation handle H is to be operated downward when the workpiece W is not locked to the workpiece support 12 (out of stock). A first restriction mechanism 51 that restricts the operation of the mechanism 6 is provided. The role of the first regulating mechanism 51 is to prevent a phenomenon in which only the ring-shaped component P is unnecessarily supplied to the assembly position A. The first restricting mechanism 51 can also be called a workpiece missing part detecting mechanism.

As shown in FIG. 16A, the first restricting mechanism 51 includes a latch pin 52 disposed on the front side of the upper end portion of the support base 2 so as to cross the storage space for the workpiece W in the left and right directions, It has a locking groove 53 formed on one side surface of one housing Bf, and a detection lever 54 that is swingably installed around the vertical axis X2 on the other side surface of the first housing Bf.
One end of the latch pin 52 is provided with a latching claw portion 52a that can enter the latch groove 53, and the other end of the latch pin 52 is provided with a contact portion 52b that can contact a part of the detection lever 54. On the rear side surface of the latch pin 52, a locking recess 52r capable of receiving a part of the side surface of the workpiece W is formed.

The latch pin 52 has a locked position where the locked claw portion 52a enters the locking groove 53 shown in FIG. 16 (d), and a locked claw portion 52a shown in FIG. It is supported so as to be displaceable to the left and right between the unlocked position retracted from the position.
A coil spring Sp5 that presses the front end portion of the detection lever 54 against the contact portion 52b of the latch pin 52 is disposed between the detection lever 54 and the first housing Bf.

  When the operation handle H is displaced downward with the work W being locked to the work support 12 at the assembly position A illustrated in FIG. 16A as shown in the operation manual, the latch pin 52 is locked. Since it is held at the unlocking position by the workpiece W entering the recess 52r, it can pass through the locking groove 53 safely as shown in FIG. Accordingly, the workpiece support 12 moves rearward toward the assembly position A and reaches the assembly position A as shown in FIG.

  On the other hand, if the operation handle H is displaced downward while the workpiece W is not locked to the workpiece support 12, the latch pin 52 is not held in the unlocked position. Therefore, as shown in FIG. 16D, immediately after the start of the movement, the latch pin 52 enters the locking groove 53 by the lateral force from the detection lever 54 and engages with the vertical locking surface 53a. Therefore, further rearward movement of the work support 12 is prevented, and the downward displacement operation of the operation handle H is also prevented.

  The locking surface 53a on the rear side of the locking groove 53 is formed vertically in order to obtain a reliable locking state with the latch pin 52. On the other hand, on the front side of the locking groove 53, the work support 12 is provided. When returning to the preset position PP, an inclined cam surface 53b is formed to allow the latch pin 52 to pass forward regardless of the presence or absence of the workpiece W. A cam surface 52d for allowing the latch pin 52 to smoothly pass through the cam surface 53b of the locking groove 53 is formed on the front side of the latched claw portion 52a of the latch pin 52 regardless of the presence or absence of the workpiece W.

(Configuration of second restriction mechanism)
As shown in FIG. 17, the component assembly apparatus 1 supplies the component when the operation handle H is to be operated in a state where the ring-shaped component P is not externally fitted to the component holder 13 (in the shortage). A second restriction mechanism 56 that restricts the operation of the mechanism 7 is provided. The role of the second restricting mechanism 56 is to prevent a phenomenon in which the work W with no ring-shaped part P mounted thereon is paid out by the pay-out mechanism 9 without the operator noticing that there is no ring-shaped part P in the part holder 13. It is in. The second restriction mechanism 56 can also be referred to as a component missing part detection mechanism.

  The second restricting mechanism 56 includes an insertion blocking portion 14 s formed below the cylindrical weight 14. As shown in FIG. 17A, the component supply stage 16 that supports and guides the ring-shaped component P sent out by the component supply plate 15 has a guide groove 16d having a width substantially equal to the outer diameter of the ring-shaped component P. The insertion preventing portion 14s is set to an outer diameter that can be engaged with the guide groove 16d. A bracket-shaped guide body 14H that slidably fits and supports the lower portion of the cylindrical weight 14 is installed in the second housing Br, and the radial displacement at the lower end of the component holder 13 is the bracket-shaped guide body 14H. Is regulated by.

  As shown in FIG. 17B, when the ring-shaped component P is present in the component space S below the component holder 13, the insertion blocking portion 14s is positioned above the space S by the ring-shaped component P. The component supply plate 15 can move under the insertion blocking portion 14s to supply the ring-shaped component P to the assembly position A. However, as shown in FIG. 17C, in a state where there is no ring-shaped component P in the component space S, the supply blocking portion 14s descends to the component space S, so the component supply plate 15 collides with the supply blocking portion 14s. Can't move any further backwards.

(Configuration of advance arrival mechanism and immediate return mechanism)
As shown in FIG. 2, the component supply mechanism 7 moves the component supply plate 15 and the component supply stage 16 proximate to the assembly position A to the assembly position A after supplying the O-ring P regardless of the position of the operation handle H. And an immediate return mechanism 58 for immediately retreating from. Here, the configurations of the preceding arrival mechanism 57 and the immediate return mechanism 58 described above will be described.

The component supply mechanism 7 is displaced forward and backward independently of the operation shaft member 61 with respect to the operation shaft member 61 extending further rearward from the rear end of the upper rack member 18 and the second housing Br. A main movable body 62 supported in a possible manner is provided.
The rear end of the first link arm 35 is connected to the rear end of the operation shaft member 61 via the lateral shaft 40 described above, and an annular trigger is provided at an intermediate position in the axial direction of the operation shaft member 61. The member 61T is fixed.
A part of the operation shaft member 61 is brought into contact with a part of the second housing Br so that the operation shaft member 61 is directed forward relative to the second housing Br based on the displacement of the operation handle H in the front-rear direction. A stopper (not shown) that restricts the backward displacement to a predetermined range is provided. The position of this stopper can be adjusted in the front-rear direction with respect to the operation shaft member 61.

  The main movable body 62 includes a housing-like main body 62a, an upper plate member 62b extending forward from the upper surface of the main body 62a, and a lower plate member 62c integrally extending forward from the lower end of the main body 62a. ing. A locking member 63 is disposed inside the main body 62a, and a locking claw 63C provided at the lower end of the locking member 63 projects downward from a through hole formed in the bottom of the main body 62a. The locking member 63 includes a lower locking position where the locking claw 63C can lock the trigger member 61T of the operation shaft member 61, and an upper non-locking position where the locking claw 63C cannot lock the trigger member 61T. And is biased toward the locking position by a coil spring Sp7.

An operated pin 63p is erected on the side surface of the locking member 63, and the tip of the operated pin 63p protrudes laterally from a through hole formed in the side surface of the main body 62a.
An operation provided with a cam surface 65a capable of temporarily switching the locking member 63 to the non-locking position by engaging with the tip of the operated pin 63p at an intermediate position in the front-rear direction of the second housing Br. Point 65 is fixed.

  A linear control shaft 66 extends rearward from the rear end of the main body 62a of the main movable body 62. The control shaft 66 includes a rear end of the control shaft 66 and a part of the second casing Br. A compression coil spring Sp9 that acts so as to be spaced apart is externally fitted. By this compression coil spring Sp9, the main movable body 62 is urged backward with respect to the second housing Br.

  Between the upper plate member 62b and the lower plate member 62c, a generally plate-like auxiliary movable body 64 is disposed so as to be movable relative to the main movable body 62 in the front-rear direction. The front end portion of the auxiliary movable body 64 constitutes the component supply stage 16 described above. On the other hand, the component supply plate 15 described above extends forward from the tip of the upper plate member 62b.

  A rear end protrusion 16 a is erected downward at the rear end of the lower surface of the auxiliary movable body 64, and an operated portion 16 b is erected on the lower surface at a position corresponding to the component supply stage 16. In addition, a regulating end face 62s that regulates the forward relative movement of the rear end protrusion 16a is formed in the middle portion of the lower plate member 62c in the front-rear direction. The component supply stage 16 is directed toward the front end position where the rear end protrusion 16a is in contact with the regulating end surface 62s by the compression coil spring Sp8 suspended between the operated portion 16b and a part of the second housing Br. It is energized.

  When the operation handle H is displaced downward from the initial state in FIG. 2, the first link arm 35 moves the operation shaft member 61 forward together with the upper rack 18 via the lateral shaft 40 as shown in FIG. 3. Move to. Then, the trigger member 61T of the operation shaft member 61 moves the main movable body 62 forward against the biasing force of the compression coil spring Sp9 via the locking claw 63C of the locking member 63.

  As the main movable body 62 moves forward, the component supply plate 15 integrated with the main movable body 62 starts moving forward. At the same time, the component supply stage 16 biased forward by the compression coil spring Sp8 also starts moving forward. To do. As a result, as shown in FIG. 3, the component supply plate 15 starts supplying one O-ring P below the component holder 13 forward, and at the same time, the front end of the component supply stage 16 is the lower end of the opening / closing arm 21. By being in contact with the portion, the gap existing behind the opening / closing arm 21 is eliminated before the front end of the O-ring P reaches the opening / closing arm 21 (preceding arrival mechanism 57).

  When the operation shaft member 61 is moved further forward, the O-ring P is moved below the opening / closing arm 21 by the component supply plate 15 that has entered beyond the rear end of the lower end of the opening / closing arm 21, as shown in FIG. It is supplied to the component holding surface 21p located. At substantially the same time as the completion of the supply, the tip of the operated pin 63p provided on the locking member 63 is operated upward by the cam surface 65a of the operation point 65, so that the locking member 63 is in the upper non-locking position. Can be switched to. Therefore, as indicated by the one-dot chain line arrow pointing rightward in FIG. 4, the component supply plate 15 integrated with the main movable body 62 is immediately returned to the rear initial position by the biasing force of the compression coil spring Sp9.

  As shown in FIG. 5, immediately after the component supply plate 15 starts the returning operation, the component supply stage 16 integrated with the auxiliary movable body 64 also faces the rear end protrusion 16a of the component supply stage 16 in the rearward direction. The front end of the component supply stage 16 is returned to the initial position spaced rearward from the lower end of the open / close arm 21 through the regulating end face 62s (immediate return mechanism 58). At this time, the trigger member 61 </ b> T of the operation shaft member 61 comes in front of the locking member 63.

  Thereafter, when the mounting of the O-ring P is completed by the component preset mechanism 10 and the component pressing mechanism 11, the first link arm 35 and the operation shaft member 61 are moved to the rear initial position based on the upward operation force from the operation handle H. Return. At the time of this return, as shown in FIG. 8, the trigger member 61 </ b> T of the operation shaft member 61 gets over the locking member 63 and automatically returns to the initial state closer to the rear than the locking member 63. Therefore, inclined guide surfaces 63G and 61G for allowing the trigger member 61T to get over the locking member 63 only in the rearward direction are formed on the locking claws 63C and the trigger member 61T of the locking member 63, respectively. ing.

  As shown in FIG. 5, the return operation of the component supply plate 15 and the auxiliary movable body 64 to the initial position by the immediate return mechanism 58 described above is performed by the positions of the operation handle H, the first link arm 35 and the operation shaft member 61. Regardless of the position, the guide roller 37 is actually completed while it is still at the intermediate position between the first cam surface 50a and the second cam surface 50b of the cam plate member 50 based on the downward displacement of the operation handle H. (Immediate return mechanism 58). Therefore, there is no possibility that the component pusher 27 that is lowered toward the peripheral surface of the cone jig in the subsequent process of pressing down the component interferes with the component supply plate 15 and the auxiliary movable body 64.
