A second holding sensor 258b for detecting whether or not the dedicated rod 50 is held is installed in the holding portion 257b.

(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 process of activating the parts feeder 210, a process of preparing the supply of the bonder cap 1, a process of moving one payout device 220, a process of moving the cap posture alignment device 230, and a process of feeding the bonder cap 1. It has a step of setting the bonder cap 1 on the dedicated rod 50. Hereinafter, each step will be described.

(Starting the parts feeder)
When a main switch (described as main SW) (not shown) is turned on. First, the material sensor 214 detects whether or not a predetermined number of bonder caps 1 are retained upstream of the single payout device 220 (1 of S1). When it is not stagnant (OFF), the upper holding plate 222a of the single payout device 220 is raised, the lower holding plate 222b is lowered (2 of S1), and then the parts motor 212 is started. Then, when the predetermined quantity has accumulated, the process proceeds to the process of preparing the supply.

(Process to prepare supply)
In the step of preparing the supply, it is detected whether or not the dedicated rod 50 is held by one or both of the first holding portion 257a and the second holding portion 257b.
For example, when the first holding sensor 258a detects the dedicated rod 50 (ON, S2 1), the set traversing cylinder 253 moves the supply unit 252 to the first position (to be exact, directly above the first position) (S2). 2), the set elevating cylinder 256 raises the set elevating portion 255 (3 of S2). Then, the first holding portion 257a rises in a state where the central axis (not shown) of the dedicated rod recess 53 substantially coincides with the central axis (not shown) of the through hole formed in the supply portion 252, and the dedicated rod 50 The dedicated rod head 52 is close to the supply unit 252 (or a part of the dedicated rod head 52 penetrates into the through hole).
Similarly, when the second holding sensor 258b detects the dedicated rod 50 (4 in S2), the set traversing cylinder 253 moves the supply unit 252 to the second position (to be exact, directly above the second position) (in S2). 5), The set elevating cylinder 256 raises the set elevating portion 255 (6 of S2).

(Process to move one payout device)
When the preparation is completed, the bonder cap 1 is dispensed from the single payout device 220 to the cap posture alignment 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 (1 of S3). Therefore, the lower holding plate 222b is raised, and "only one" of the bonder cap 1 stopped on the downstream side is discharged to the downstream side (2 of S3). At this time, the payout air A1 is blown out to promote the movement of the bonder cap 1 (3 of S3).
Further, the lower holding plate 222b is lowered (4 in S3), then the upper holding plate 222a is raised (5 in S3), and the bonder cap 1 held by the upper holding plate 222a is placed at the position of the lower holding plate 222b. Move to.

(Process of moving the cap posture alignment device)
When the bonder cap 1 dispensed from the one-piece dispensing device 220 has entered the receiving portion 10 of the component alignment jig 100, the extrusion cylinder 231 moves the extrusion plate 31 in the direction of the overturning portion 20 (1 of S4). Then, the bonder cap 1 falls and is aligned with the small diameter portion 3 on the downstream side (see (a) and (b) of FIG. 5).
At this time, the extruded air A2 blows out in the direction of the overturning path 21 (2 of S4), and the holding air A3 blows out in the direction of the bottom surface 21a of the overturning path (3 of S4). It is discharged vigorously into the hose 234.

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

(Process of setting the bonder cap on the special rod)
The arrival sensor 254 detects that the bonder cap 1 has reached the supply unit 252 (1 of S6). When the bonder cap 1 arrives (ON), the dedicated rod 50 stands by directly under the supply unit 252, so that the small diameter portion 3 vigorously penetrates into the dedicated rod recess 53. That is, the bonder cap 1 is set on the dedicated rod 50.
Then, the set elevating part 255 that has been raised descends (2 of S6).
On the other hand, when the bonder cap 1 has not reached (OFF), it is considered that each of the above steps is not functioning, so the process returns to the step of activating the parts feeder 210 (1 of S1).

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

The above is an explanation of the basic operation flow, and since each operation may have a time delay or a waiting time, some operations may be performed in parallel at the same time. It may progress or the front and back of some movements may be reversed.
For example, in the latter half of the preparation process (2 in S2, 3 in S2, 5 in S2, 6 in S2), one payout process (1 to 5 in S3) or a cap posture alignment process (1 to S4 in S4). It may be executed in parallel with 3), and after confirming that the set elevating part 255 has risen, the air supply air A4 may be blown out.
Further, the air supply air A4 is blown out at a timing delayed by a predetermined time from the start of the push cylinder 231 of the cap posture alignment device 230, but instead, the bonder cap 1 has passed through the air supply box 241. A sensor for detecting may be installed to blow out the air supply air A4 based on the detection of the sensor.

(Action effect)
As described above, the bonder cap feeder 200 is configured 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 penetrated into the dedicated rod recess 53 of the dedicated rod 50.
At this time, the worker only needs to hold the dedicated rod 50 in the first holding portion 257a or the second holding portion 257b of the cap set device 250, so that the work load is significantly reduced.
Further, for example, the dedicated rod 50 grasped by the right hand can be held by the first holding portion 257a and the dedicated rod 50 grasped by the left hand can be held by the second holding portion 257b in one operation, and the bonder cap 1 is set. Since the special rod 50 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 one operation, the work can be speeded up and the holding work and the taking out work can be performed. In the meantime, it will be possible to carry out other work.
Further, since each device constituting the bonder cap feeder 200 is small and lightweight, there are few restrictions on the installation position. Further, since the air supply hose 242 can be lengthened and the bonder cap 1 can be aired far away by the air supply device 240, the cap set device 250 can be installed at a position far away from the cap posture alignment device 230. It will be possible.

(Modification example)
The present invention does not limit the number of holding portions, and the same holding portions as the first holding portion 257a may be added and fixed to the set elevating portion 255. Then, for example, if the number of holding portions is set to 4, the worker can hold a total of 4 bonder caps 1 at one timing, or a total of 4 dedicated rods 50 in which the bonder cap 1 is set can be held once. It can be taken out at the timing of.
Further, the air feeding hose 242 may be branched and the cap set device 250 may be connected to each end of the branched air feeding hose 242. At this time, a switching means for switching the air feeding direction is installed at the branch portion.
