The suction nozzle 12 is provided so as to move up and down in conjunction with the intermittent rotation of the transport rotating disk 11 by an interlocking mechanism (not shown). As the suction nozzle 12 descends, the tip of the suction nozzle 12 descending from above the straight portion 22 enters the conveyance path 221 of the straight portion 22 as indicated by an arrow YB in FIG. . Once the transport rotary disk 11 stops operating at the suction position, the suction nozzle 12 is positioned close to the upper side of the element t located at the component supply position, and the suction nozzle is caused by the negative pressure of a negative pressure supply source (not shown).

(Recovery Department)
As shown in FIGS. 2 and 4, the recovery unit 4 includes a separation fluid applying unit 41 that separates the element t from the suction nozzle 12, a counting unit 5, and a negative pressure supply unit 52. The element t transported to the recovery unit 4 is ejected from the suction nozzle 12 by the pressurized fluid by the separation fluid applying means 41 at the element recovery port 43, and is transferred to the storage unit 7 to be described later through the recovery path. Is done. When the element t is detached from the suction nozzle 12, the element t is blown off by the separation fluid applying means 41 and introduced into the first introduction pipe 44 having a curvature in the longitudinal plane. The transfer direction of the element t is changed from the horizontal direction to the vertical direction by the first introduction pipe 44 and is guided so as to be loaded with gravity, so that the transfer speed is increased. The element t is first counted when passing through the counting means 5 after flowing through the first introduction pipe 44. Next, sorting is performed in the sorting means 6. In this classification, the element t is selected for each performance classification of the inspection result by the inspection unit 3 and automatically counted and stored in a storage container 71 of the storage unit 7 described later. The curvature of the first introduction pipe 44 is not limited to the vertical plane, but includes a plane inclined with respect to the vertical plane and is a curvature in the vertical plane in which gravity is applied to the element t. Good.

  As shown in FIG. 4, separation fluid application means 41 that applies fluid pressure (air pressure) to the recovery unit 4 to forcibly transfer the element t from the transport unit 2 to the first introduction pipe 44, and the first A negative pressure supply means 52 that jets a compressed fluid downstream of the inlet pipe 44 and applies a pressure, which will be described later, to the element recovery port 43 on the inlet side of the recovery section 4, and is transferred from the first inlet pipe 44. A counting unit 5 that counts the element t by the sensor while passing the element t, and a sorting unit 6 that classifies the element t according to the performance classification of the inspection result by the inspection unit 3.

The separation fluid applying unit 41 includes a compressed air ejection port 42 that ejects air supplied from a compressed air supply source (not shown). The compressed air ejection port 42 is provided along the conveyance path of the conveyance unit 2 on the downstream side of the inspection unit 3. When the suction nozzle 12 is located at the lower limit, the compressed air ejection port 42 injects compressed air supplied from an air supply source (not shown) toward the element recovery port 43 and is sucked and held by the suction nozzle 12. The element t is blown off to the element recovery port 43 side.
The element recovery port 43 is opened facing the compressed air outlet 42 of the recovery unit 4 and is sucked through the first introduction pipe 44 by a negative pressure by a negative pressure supply source described later. .

  In the recovery part 4 having such a configuration, the suction-held element t enters the inlet part of the recovery part 4 shown in FIG. When positioned between the recovery port 43 and the compressed air supplied from a compressed air supply source (not shown), the compressed air is blown from the compressed air outlet 42 to the element t, and the negative pressure of the negative pressure supply source described later enters the element recovery port 43. The element t is introduced into the tubular element recovery port 43 by releasing the suction by the suction nozzle 12.

  In FIG. 4, the element t introduced into the element recovery port 43 is guided while flowing through the tubular first introduction pipe 44. The first introduction pipe 44 extends from the element recovery port 43 in a substantially horizontal direction, and then passes through the first introduction pipe 44 having a curvature bent in a substantially quarter arc shape so that the element t is moved in the direction of gravity. Guide it to drop. When the element t is introduced into the tubular first introduction pipe 44 having a curvature by injection of compressed air from the compressed air outlet 42, the element t is retained by the retention of the air injected from the first introduction pipe 44. It may be subject to air resistance (flow resistance due to fluid pressure). When the element t receives such an air resistance due to the stagnation of air, the flow rate is reduced, and the separation efficiency of the element t is lowered.

  In the embodiment of the present invention, in order to avoid the air resistance in the first introduction pipe 44 having such a curvature, a hard or soft tubular member is used for the first introduction pipe 44, and is appropriately used. A pressure relief portion for air resistance is provided by forming a gap with a shape hole, slit or the like. The air resistance pressure relief portion only needs to have a gap shape that prevents the element t that flows through the inside thereof from falling off. In the illustrated first introduction pipe 44, a coil spring, which is a spring member wound in close contact with a pressure relief portion formed in an arc-shaped curvature portion, is used. One of the coil springs is fitted to the outer periphery of the connection portion 46 of the element recovery port 43, and the other is fixed so as to face the inlet hole of the passage portion 51 of the counting unit 5. Are connected so that a recovery passageway is formed between them. A gap is generated in the wound portion on the pull side (the side with the larger radius of curvature) of the portion where the coil spring is bent into a substantially quarter arc shape. Since the injected air is discharged from this gap, the problem of air retention can be solved. For this reason, the air resistance in the first introduction pipe 44 formed by the closely wound coil spring having the curvature is eliminated, so that the flow speed of the element t in the gravity direction is increased, and the speed of the separation can be increased.

(Counting means)
The counting means 5 stretches a light beam such as a planar or linear infrared ray through the passage 51 through which the element t passes, and counts when the light beam is blocked by the passage of the element t. It is configured.

(Negative pressure supply means)
The negative pressure supply means 52 is disposed adjacent to the counting means 5 and downstream thereof. As shown in FIG. 4, the negative pressure supply means 52 is provided on the holding portion 15 erected on the base plate 14 of the element sorting storage device 10 (see FIG. 2). The counting means 5 is supported upright on the negative pressure supply means 52.
The negative pressure supply means 52 ejects a compressed fluid such as air from a negative pressure supply source (not shown) from the negative pressure supply port 55 along the inner wall of the passage portion 51, thereby causing the element t in the recovery passage to be applied to the element t in the recovery passage. In contrast, a negative pressure suction force is generated. This negative pressure supply means utilizes the Coanda effect by a known Coanda nozzle means. The negative pressure supply means 52 of this embodiment includes a head member 53 that forms a compressed fluid distribution chamber, and a nozzle member 54 that guides the compressed fluid from the distribution chamber of the head member 53, and a negative pressure supply source (not shown). The compressed fluid to be supplied is ejected from a Coanda slit formed in the negative pressure supply port 55. The nozzle member 54 has a jet passage that is inclined with respect to the downstream side of the passage portion 51 of the recovery passage with respect to the Coanda slit of the negative pressure supply port 55. The negative pressure supply port 55 is arranged in an annular shape. The negative pressure supply means 52 injects a negative pressure suction force into the first introduction pipe 44 by injecting the compressed fluid from the negative pressure supply port 55 toward the downstream side of the recovery passage of the element t along the pipe wall. Then, the element t in the element recovery port 43 and the first introduction pipe 44 is sucked and quickly passed to the separation means 6.

(Separation means)
As shown in FIG. 4, the sorting means 6 is formed of a rotating body having one radial sorting passage 62 formed in the radial direction for sorting the element t and guiding it to the storage container 71 (see FIG. 2). Yes. A hatched portion on the opposite side of the radial sorting passage 62 (the right side in FIG. 4) indicates a counter balancer portion for balancing the balance. In the illustrated embodiment, the separating means 6 has a rotating feeder 61 and a shaft cylinder 63 formed in an umbrella-shaped conical shape and is rotatably held by a bearing 67. Although described, the present invention is not limited to this, and for example, a bifurcated shape having a counter balancer portion may be used.
The radial separation passage 62 is formed along the outer surface of the cone of the rotating feeder 61 with a predetermined inclination angle, and the element t flows down in the radial separation passage 62. Yes. The inlet opening 62a of the radial separation passage 62 opens facing the passage hole of the negative pressure supply port 55, and is slightly larger than the diameter of the passage hole of the negative pressure supply port 55 of the element t so that the element t can be easily received. It has a large diameter. The shaft cylinder 63 of the sorting means 6 is connected to the rotating shaft 68 of the servo motor M.

  The rotation shaft 68 of the servo motor M is connected to the shaft cylinder 63 of the sorting means 6 through a bearing portion 66 fixed to the support plate 20 provided at the opening of the base plate 14. The shaft cylinder 63 of the sorting means 6 and the rotating shaft 68 of the servo motor M are integrally connected by a coupling pin. Thereby, the sorting means 6 is driven in synchronization with the servo motor M. The servo motor M is configured by a plurality of second introduction pipes 65, 65 that connect the outlet opening 62 b of the radial separation passage 62 to the storage container 71 based on the inspection result of the element t by the inspection unit 3 by a control device (not shown). It is controlled to select and connect one second introduction pipe 65 from among them. Accordingly, the element t is one second introduction pipe 65 selected from the outlet opening 62b of the radial separation passage 62 so that the element t is separately stored in the storage container 71 in a state classified according to the distribution range of the inspection data. It is transferred to the storage hose 64 allocated through the storage container 71 and is separately stored in the storage container 71.

  The radial separation passage 62 has its inner diameter gradually reduced from the inner diameter on the inlet opening 62a side formed slightly larger than the diameter of the passage hole of the negative pressure supply port 55 to the outlet opening 62b side. The inner diameter of the radial separation passage 62 is not limited to this, and may be the same inner diameter from the inlet opening 62a side to the outlet opening 62b side.

  In the outlet opening 62b of the radial separation passage 62, a plurality of second introduction pipes 65, 65 formed for storage separation are provided opposite to the outlet opening 62b. Similar to the first introduction pipe 44, the second introduction pipe 65 is formed with a gap with a hole, a slit or the like of an appropriate shape that does not cause the element t to drop off. Parts are provided. The second introduction pipe 65 is formed of a hard or soft tubular member. In the present embodiment, a coil spring that is a spring member wound in close contact like the first introduction pipe 44 is used. The upper part of the coil spring for storage has an inclination angle that matches the inclination angle of the radial sorting passage 62 of the rotary feeder 61, and the lower part thereof is formed vertically. The upper end of the coil spring for storage is supported by a mounting member 21 projecting from the support plate 20 so that the opening thereof corresponds to the outlet opening 62b of the radial sorting passage 62, and the lower end thereof is supported by the support plate. 20 is connected to the introduction pipe connection hole 23 formed in the apparatus 20. A gap is generated in the wound portion on the pulling side (the side with the larger curvature radius) of the portion where the coil spring is bent in an arc shape. From this gap, the air injected from the negative pressure supply means 52 into the second introduction pipe 65 is discharged, so that the problem of air resistance due to retention of air can be solved. For this reason, the air resistance in the second introduction pipe 65 formed by the closely wound coil spring having the curvature is eliminated, so that the separation speed of the element t is increased and the separation efficiency can be improved.

  As described above, in the recovery section 4, the recovery passage for transferring the element t is composed of the first introduction pipe 44, the passage section 51, the radial separation passage 62, and the second introduction pipe 65.

  Note that openings of a plurality of storage hoses 64 connected to the storage containers 71 (see FIG. 2) of the storage unit 7 are connected to the lower side of the introduction pipe connection hole 23 formed in the support plate 20. As shown in FIG. 5, the support plate 20 is formed with a plurality of introduction pipe connection holes 23, 23 connected to the opening of the storage hose 64. In the drawing, 32 inlet pipe connection holes 23 arranged in an annular shape are equally provided. As described above, since the diameter size of the sorting means 6 can be formed small, each storage hose 64 connected to the storage container 71 can be arranged vertically. As a result, the flow rate at which the element t falls within the storage hose 64 is increased, so that the separate storage speed of the element t can be improved.

(Storage section)
As shown in FIG. 2A, the storage unit 7 is disposed below the element sorting storage device 10. A plurality of storage containers 71 are placed on a drawer shelf 74 that can be stored and pulled out along a guide rail provided on the bottom plate 72 of the element sorting and storing apparatus 10. Each storage container 71 is arranged at a predetermined position on the drawer shelf 74, and the storage containers 71 are divided so as to be stored for each inspection classification of the separated element t, and a phase mark shape, etc. As shown in FIG. 6, they are arranged in an orderly manner so as to fit in a predetermined arrangement position. As a result, the element t is stored in the storage container 71 in a state where the quantity is measured and sorted according to the inspection classification sorted into the distribution range of the performance of the inspection data.
The storage container 71 is placed on one bottom plate 72 in FIG. 6, but may be placed on a plurality of shelf plates (not shown) as other forms. Further, the number of elements t accommodated in each storage container 71 for each classification is displayed on a display device (not shown) for each storage container 71.

  Storage hoses 64, 64,... Are connected to the upper portions of the storage containers 71, 71,. The storage container 71 can be taken in and out from the storage opening of the base A (not shown) by the drawer shelf 74. As shown in FIG. 6, the drawer shelf upper plate 75 provided above the drawer shelf 74 is arranged on two predetermined side surfaces adjacent to each other of the storage containers 71 with different patterns as the phase mark shape. Joint convex pieces and row engaging convex pieces are formed. FIG. 6 shows an example of patterns arranged in 4 rows and 8 columns. On the drawer shelf upper plate 75 of the storage container 71, fitting grooves are formed at positions corresponding to the column engagement convex pieces and the row engagement convex pieces having different patterns. The fitting groove formed so as to correspond to the convex piece of the storage container 71 by this phase mark-shaped pattern allows each storage container 71 to be placed at a predetermined position without making a mistake. For this reason, even if the storage container 71 is erroneously attached, the storage container 71 is not set unless the phase mark pattern matches, so that erroneous attachment can be prevented.
