The receiving portion 10 is formed in a cylindrical bottomed hole (hereinafter, referred to as “receiving channel 11”) having a receiving channel central axis 19 and a wall surface on one side of the receiving channel 11 (same as a downstream wall surface). An overturning portion-side opening 12 and an extruding portion-side opening 13 formed on the other wall surface of the receiving path 11 and facing the overturning portion-side opening 12 are provided. The overturning portion 20 is integrally arranged so as to communicate with the pushing portion, and the pushing portion 30 is arranged facing the pushing portion side opening portion 13.
For convenience of the following description, the direction of the central axis of the receiving path 11 (hereinafter, referred to as “receiving path central axis 19”) is “Z direction”, the downstream direction is “X direction”, and the direction perpendicular to the Z direction and X direction. The direction is referred to as “Y direction”.

In addition, the receiving path 11 is formed in a cylindrical shape in an area close to a top surface thereof (hereinafter, referred to as a “receiving path top surface 11b”) (see FIG. 3B), and a hose (not shown) for receiving the bonder cap 1 is provided. (Not shown), and the area where the tipping-side opening 12 is formed has a rectangular cross section (XY cross section) (see FIG. 3D).
Then, the bonder cap 1 is received in the receiving path 11 in the “−Z direction” with the cap central axis 9 substantially parallel to the receiving path central axis 19, and is extruded in the “+ X direction” by the pusher 30. Then, it enters the falling part 20 (this will be described in detail separately).

(Falling part)
The overturning portion 20 is provided with a rectangular overturning passage 21 that is in communication with the overturning portion side opening 12 of the receiving path 11 and that has a rectangular section (YZ section) for receiving the bonder cap 1. A bottom groove 22 is formed on the bottom surface of the falling road 21 (hereinafter referred to as “falling road bottom surface 21 a”) so that the small diameter portion 3 of the bonder cap 1 can enter and the large diameter portion 5 cannot enter. A top surface groove 23 into which the small diameter part 3 can enter and the large diameter part 5 cannot enter is formed on the top surface (hereinafter referred to as “top surface 21b”). At this time, the bottom surface of the bottom groove 22 (hereinafter referred to as “bottom groove bottom surface 22a”) and the receiving path bottom surface 11a form the same plane.

Similarly, the width B3 (same as the distance in the Y direction) of the top surface groove 23 is larger than the small diameter portion outer diameter D3 and smaller than the large diameter portion outer diameter D5 (D3 <B3 <D5).
The width B1 (same as the distance in the Y direction), which is the distance between a pair of side surfaces of the overturning road 21 (hereinafter referred to as “overturning road side surface 21c”), is larger than the large diameter portion outer diameter D5 (B1> D5).
Further, the depth H2 (same as the distance in the Z direction) of the bottom groove 22 is slightly smaller than the small diameter portion length L3 (H2 <L3), and the height H1 of the overturning road 21 (overturning road bottom surface 21a and overturning road top surface 21b). And the depth H2 of the bottom groove 22 are larger than the large diameter portion length L5 and smaller than the cap length L1 (L5 <(H1 + H2) <L1). The sum of the height H1 of the overturning path 21, the depth H2 of the bottom groove 22, and the depth H3 of the top groove 23 is larger than the cap length L1 ((H1 + H2 + H3)> L1).

(Extrusion part)
The push-out portion 30 is provided on the push-out plate 31 that penetrates the push-out portion side opening 13 of the receiving portion 10 and is inserted into the falling portion side opening 12 so as to be able to advance and retreat in the substantially X direction, and is mounted on the jig substrate 101.

Then, the small-diameter portion 3 enters the top surface groove 23 and the step portion 4 (same at a position near the small-diameter portion 3 of the large-diameter portion 5) enters the overturning path 21, but the large-diameter end surface of the large-diameter portion 5 6 (the same as the position away from the small diameter portion 3) is in contact with the bottom groove end surface 24. Therefore, the bonder cap 1 falls down in the clockwise direction, and enters the overturning path 21 while overturning. Then, the small-diameter portion 3 is positioned downstream on the overturning path bottom surface 21a, and the cap central axis 9 is moved in the X direction. Become parallel.
In addition, since the air blown out from the overturn part air hole 26 presses the bonder cap 1 against the overturned road bottom surface 21a, the bonder cap 1 is prevented from jumping up.
Further, the air blown out from the push-out portion air hole 34 pushes the fallen bonder cap 1 to the discharge portion 40. However, if the overturn path 21 is not horizontal and the discharge portion 40 side is low, the push-out portion air hole is provided. 34 may be removed and moved by its own weight.

A through-hole (not shown) through which the bonder cap 1 can pass is formed in the supply section 252, and an arrival sensor 254 for detecting whether or not the bonder cap 1 has entered the through-hole is provided.
A set elevating unit 255 is arranged between the pair of set columns 251b so as to be able to move up and down in a posture parallel to the set rail 251c, and the set elevating unit 255 is moved up and down by a set elevating cylinder 256 fixed to the set rail 251c. .
Further, a first holding section 257a is fixed to one side (hereinafter, referred to as a “first position”) of the set elevating section 255, and a second holding section is fixed to the other side (hereinafter, referred to as a “second position”) of the set elevating section 255. The part 257b is fixed.

The first holding portion 257a and the second holding portion 257b have the same shape, are formed with a substantially V-shaped groove, and the groove is formed of an elastically deformable material. Therefore, the worker can grasp the special rod shaft 51 and push the special rod shaft 51 into the deepest part of the groove with a small force. Then, when the worker releases the special rod shaft portion 51 when pushed, the special rod head 52 is locked on the upper surface of the first holding portion 257a or the second holding portion 257b, and the special rod head 52 is pulled out unless pulled out with a slight force. The rod 51 cannot be dropped off.
Further, a first holding sensor 258a for detecting whether or not the dedicated bar 50 is held by the first holding portion 257a is installed in the first holding portion 257a, and similarly, the second holding portion 257b is provided with a first holding sensor 258a. A second holding sensor 258b that detects whether the dedicated bar 50 is held by the second holding unit 257b is provided.

(Operation of bonder cap feeder)
Hereinafter, the operation of the bonder cap feeder 200 will be described with reference to FIGS. 7 and 8.
Such operations include a step of activating the parts feeder 210, a step of preparing the supply of the bonder cap 1, a step of moving the one-piece payout device 220, a step of moving the cap attitude aligning device 230, and a process of pumping the bonder cap 1. And a step of setting the bonder cap 1 to the exclusive rod 50. Hereinafter, each step will be described.

(Activation of parts feeder)
When a main switch (not shown) (not shown) is turned on. First, the material presence sensor 214 detects whether or not a predetermined number of bonder caps 1 are staying upstream of the one piece dispensing device 220 (S1-1). When it is not staying (OFF), the upper pressing plate 222a of the single payout device 220 is raised, and the lower pressing plate 222b is lowered (S1-2), and then the parts motor 212 is started. Then, when the predetermined quantity has accumulated, the process proceeds to the step of preparing the supply.

(Process of preparing supply)
In the step of preparing the supply, it is detected whether the dedicated bar 50 is held on one or both of the first holding unit 257a and the second holding unit 257b.
For example, when the first holding sensor 258a detects the dedicated bar 50 (ON, 1 of S2), the set traversing cylinder 253 moves the supply unit 252 to the first position (more precisely, immediately above the first position) (S2). (2), the set elevating cylinder 256 moves up the set elevating unit 255 (S2-3). Then, with the central axis (not shown) of the dedicated rod recess 53 substantially coinciding with the central axis (not shown) of the through-hole formed in the supply portion 252, the first holding portion 257a rises, and The dedicated rod head 52 approaches the supply unit 252 (or a part of the dedicated rod head 52 enters the through hole).
Similarly, when the second holding sensor 258b detects the dedicated bar 50 (4 in S2), the set traversing cylinder 253 moves the supply unit 252 to the second position (more precisely, immediately above the second position) (S2). 5), the set elevating cylinder 256 moves up the set elevating unit 255 (S2-6).

(Process of moving one dispensing device)
When the preparation is completed, the bonder caps 1 are dispensed from the individual dispensing device 220 to the cap attitude aligning device 230 "one by one".
That is, the upper holding plate 222a is lowered so that the bonder cap 1 staying on the upstream side does not move to the downstream side (S3-1). Then, the lower holding plate 222b is lifted, and “only one” pays out the bonder cap 1 held on the downstream side to the downstream side (S3-2). At this time, the delivery air A1 is blown out to promote the movement of the bonder cap 1 (S3-3).
Further, the lower holding plate 222b is lowered (S3-4), and then the upper holding plate 222a is raised (S3-5), and the bonder cap 1 stopped by the upper holding plate 222a is moved to the position of the lower holding plate 222b. Move to.

(Process of moving the cap attitude alignment device)
When the bonder cap 1 dispensed from the single dispensing device 220 enters the receiving portion 10 of the component alignment jig 100, the pushing cylinder 231 moves the pushing plate 31 toward the tipping portion 20 (S4-1). Then, the bonder cap 1 falls down and is aligned with the small-diameter portion 3 on the downstream side (see (a) and (b) of FIG. 5).
At this time, the pushing air A2 blows out in the direction of the falling road 21 (S4-2), and the holding air A3 blows out in the direction of the falling road bottom surface 21a (S4-3), so that the bonder cap 1 is discharged while the upward movement is suppressed. It is discharged vigorously into the hose 234.

(Pneumatic)
The bonder cap 1 discharged into the discharge hose 234 passes through the pneumatic box 241 and stops at the lowest position of the pneumatic hose 242. Then, the pneumatic air A4 is blown into the pneumatic hose 242 via the air hose 243 (S5). Then, the bonder cap 1 is vigorously pumped toward the cap setting device 250.

(Process of setting the bonder cap on a special stick)
The arrival sensor 254 detects that the bonder cap 1 has reached the supply unit 252 (S6-1). When the bonder cap 1 arrives (ON), the dedicated bar 50 stands by immediately below the supply unit 252, so that the small-diameter portion 3 vigorously enters the dedicated bar recess 53. That is, the bonder cap 1 is set on the special bar 50.
Then, the set elevating unit 255 that has been ascended moves down (S6-2).
On the other hand, when the bonder cap 1 has not reached (OFF), it is considered that the above-mentioned steps are not functioning, and the process returns to the step of activating the parts feeder 210 (S1-1).

In addition, when the dedicated bar 50 is not held in the second holding unit 257b, that is, when the dedicated bar 50 is held in the first holding unit 257a (S6-3), the dedicated bar 50 is transferred from the first holding unit 257a. Is taken out (S6-4), a series of steps is completed, and as long as the main switch is turned on, the process returns to the step of activating the parts feeder 210.
On the other hand, when the dedicated bar 50 is held by the second holding unit 257b (S6-3), it is determined whether the supply unit 252 is stopped at the second position (S6-5). That is, when the supply unit 252 is stopped at the first position instead of the second position, the bonder cap 1 is not set on the dedicated rod 50 held by the second holding unit 257b. Proceed to.
When the dedicated bar 50 is held by the second holding unit 257b and the supply unit 252 is stopped at the second position (S6-5), the bonder cap 1 is attached to the dedicated bar 50 held by the second holding unit 257b. Is set. At this time, the bonder cap 1 may also be set on the dedicated bar 50 held by the first holding portion 257a. Therefore, when the dedicated bar 50 is taken out of the first holding portion 257a (S6-6) and the dedicated bar 50 is taken out of the second holding portion 257b (S6-7), a series of steps is completed, and the main switch is turned off. As long as is input, the process returns to the step of activating the parts feeder 210.

The above is a description of the basic operation flow.Since each operation may have a time delay or a waiting time, some operations may be performed in parallel. There is a case where progress is made or before and after some operations are reversed.
For example, in the latter half of the preparation process (2 of S2, 3 of S2, 5 of S2, 6 of S2), a single payout process (5 of S3 to 5 of S3) or a cap attitude alignment process (1 to S4 of S4). The pneumatic air A4 may be blown out after executing in parallel with 3) and confirming that the set elevating unit 255 has risen.
Further, the pneumatic air A4 is blown out at a timing delayed by a predetermined time from the activation of the pushing cylinder 231 of the cap attitude aligning device 230, but instead, it is determined that the bonder cap 1 has passed through the pneumatic box 241. A sensor for detection may be provided, and the pneumatic air A4 may be blown out based on the detection of the sensor.

(Effect)
As described above, the bonder cap feeder 200 is constituted by a device having a simple structure, and the bonder caps 1 are automatically dispensed one by one and aligned so that the small diameter portion 3 is on the downstream side. 3 is set in a state where it has entered the exclusive rod recess 53 of the exclusive rod 50.
At this time, the worker only needs to hold the dedicated rod 50 on the first holding portion 257a or the second holding portion 257b of the cap setting device 250, so that the work load is greatly reduced.
Further, for example, the dedicated bar 50 grasped by the right hand can be held by the first holding portion 257a, the dedicated bar 50 grasped by the left hand can be held by the second holding portion 257b by one operation, and the bonder cap 1 is set. Can be taken out from the first holding portion 257a with the right hand and from the second holding portion 257b with the left hand in a single operation. In between, other operations can be performed.
Furthermore, since each device constituting the bonder cap feeder 200 is small and lightweight, there is little restriction on the installation position. Furthermore, since the pneumatic hose 242 can be lengthened and the bonder cap 1 can be pneumatically fed by the pneumatic device 240, the cap setting device 250 can be installed at a position far away from the cap position alignment device 230. Will be possible.

(Modification)
