  Hereinafter, based on FIG. 1 to FIG. 9, the conveyance path is vibrated, the parts are conveyed by the vibration, aligned and supplied in a predetermined posture, and a plurality of the parts are put together, and then the parts are collected. An embodiment of a vibration-type component supply device that can facilitate the storage and storage of components will be described.

  This vibratory component supply device 1 is a vibratory feeder in which a straight-feeding feeder (takeout feeder) 3 having a U-shaped vertical cross section and inclined downward is connected (connected) to the discharge end of a bowl feeder 2 and fixed. Is provided on the base 1A, and the vibration feeder having a vibration drive source attached to the base 1A is vibrated to vibrate the conveying path of the vibration feeder. 5 are arranged in a predetermined posture, and are sequentially conveyed to the component take-out portion 8A inclined downward to the discharge end of the chute 8 of the linear feeder 3, for example, in units of ten, and the collected components 5 are stored.・ It is provided for the convenience of storage. The bottom of the bowl 4 has a high center and is inclined concentrically and outwardly.

  The parts 5 to be aligned and supplied are parts having directionality at least in the traveling direction when moving on the conveyance path, and the arrow direction shown in FIG. Bottom wall 5A, a side wall 5B rising perpendicular to the bottom wall 5A, and a rear wall 5C slightly inclined with respect to the bottom wall 5A. A vertical piece 5D bent downward is formed at the front end of the bottom wall 5A in the moving direction, and an insertion hole 5E described later is formed in the rear wall 5C. This part 5 has dimensions (unit: millimeters) as shown in FIG. 4 and is, for example, a bracket welded to one part, but is not limited to the shape shown in the figure.

  The bowl feeder 2 is formed with a track 7 as a conveying path that spirally rises from its bottom on the outside of the bowl 4, and the uppermost discharge end of the track 7 passes through the conveying path of the linear feeder 3. It is connected to the supply end of the chute 8 to be formed. That is, the component 5 thrown into the bottom of the bowl 4 is gradually conveyed on the track 7 and is transferred from the discharge end at the top of the track 7 to the supply end of the chute 8 of the linear feeder 3. Yes.

  Reference numeral 9 denotes a first restricting piece fixed to the bottom wall 7A forming the uppermost track 7. The conveying width of the part 5 of the track 7 is projected from the peripheral side wall 7B1 side of the track 7 to the inside. The parts 5 are narrowed so that only one can pass through them, and the parts 5 are moved one by one so that the longitudinal direction is the traveling direction. In this case, when two adjacent parts 5 are to be transported, the inner part 5 falls on the bottom surface of the bowl 4.

  Further, since the width of the component 5 is 20 mm and the minimum conveyance path width narrowed by the first restriction piece 9 is 15 mm, even if the parts 5 are arranged to be conveyed one by one by the first restriction piece 9, When the traveling direction in which the rear wall 5C shown in FIG. 5 is located upstream is normal, the side wall 5B of the component 5 is on the peripheral side wall 7B1 side of the track 7 and the center of gravity is located on the outer side. Even if the width is small in the direction perpendicular to the conveying direction of the rear wall 5C, it does not fall on the bottom surface of the bowl 4, but the traveling direction (arrow direction) in which the rear wall 5C shown in FIG. If the side wall 5B of the component 5 is on the bowl 4 side and the center of gravity is located on the inner side, and the width of the transport path is small in the direction perpendicular to the transport direction of the rear wall 5C, 4 will fall on the bottom surface.

  Then, at a substantially central position of the length of the first restricting piece 9, when the part 5 moving on the transport path narrowed by the first restricting piece 9 is in an abnormal direction, the second restricting the second restricting piece 9 is dropped to the bowl 4. A restriction piece 10 is provided. That is, the second restriction piece 10 has a generally U-shaped longitudinal section, and includes an upper piece 10A and both side pieces 10B1 and 10B2, and the outer piece 10B1 is fixed to the outer side of the peripheral side wall 7B of the uppermost track 7. At the same time, the inner piece 10B2 is fixed to the peripheral side wall 7B2 of the next stage track 7, and the rear end of the inner piece 10B2 is provided with an alignment piece 10C inclined inward toward the rear end.

  That is, even when the traveling direction in which the rear wall 5C is located downstream is normal, as shown in FIG. 7, when the front is inclined toward the bowl 4 with respect to the traveling direction (arrow direction), In a state where the width of movement on the conveyance path is large, the front part of the component 5 comes into contact with the alignment piece 10C and falls onto the bottom surface of the bowl 4. Further, as shown in FIG. 8, even when the component 5 is lying on the side wall 5 </ b> B, the front portion of the component 5 is in a state where the width of movement on the conveyance path in the direction of the arrow is large. Falls on the bottom surface of the bowl 4 in contact with the alignment piece 10C.

  Further, when an overlap detection device 11 made of, for example, a light reflection type sensor is disposed at a predetermined interval from the first restriction piece 9, the component 5 is conveyed in a state of being stacked two times. Accordingly, the upper end position of the upper part 5 becomes a higher level, and the emitted light hits the upper part 5 and is reflected to receive the reflected light. The state can be detected.

  Reference numeral 13 denotes an exclusion cylinder composed of an air cylinder. When the overlap detection device 11 detects the overlap state of the two parts 5, the control device 15 that receives the detection signal from the overlap detection device 11 gives an operation instruction. As shown in FIG. 9, when the exclusion cylinder 13 receives this operation instruction signal, the rod is extended through the insertion hole 7C formed in the peripheral side wall 7B1 to prevent the part from going. At the same time, the component 5 is dropped onto the bottom surface of the bowl 4. After dropping in this way, the control device 15 operates the exclusion cylinder 13 again to contract the rod.

  Instead of the exclusion cylinder 13, another exclusion device such as an electromagnetic solenoid or an air blowing device may be used. Further, the control device 15 may be constituted by a microcomputer or the like.

  A third restricting piece 16 is disposed at a position downstream of the position where the exclusion cylinder 13 is disposed, and the third restricting piece 16 is narrowed so that only one conveying width of the part 5 of the track 7 can pass. At the upstream end of the piece 16, a constant blocking cylinder 17 is disposed as a blocking body, which will be described later, and is constituted by an air cylinder.

  In the present embodiment, the constant cutoff cylinder 17 is disposed at an upstream position of the linear feeder 3, but may be provided in the middle of the linear feeder 3. In place of the constant blocking cylinder 17, another blocking body such as an electromagnetic solenoid may be used.

  And it is made to convey sequentially to the component extraction part 8A inclined to the downward direction formed in the discharge end of the chute 8 of the linear feeder 3 connected to the discharge end of the bowl feeder 2, The component 5 which passed this part extraction part 8A is conveyed. For example, the collection device 18 that collects in units of 10 will be described below.

  A drive motor 19 has a belt 22 stretched between a drive pulley 20 and a driven pulley 21 fixed to the output shaft. And the upper part of the rotating shaft 23 of the driven pulley 21 is fitted and fixed in the center hole of the rotating plate 24, and the upper end of the rotating shaft 23 protruding from the rotating plate 24 is inserted into the insertion pin 25 and this insertion at every 90 degrees. Four guide pins 26 of the component 5 that are bent so that their tips are separated from the insertion pins 25 are fixed at positions slightly apart from the pins 25. The rotating plate 24 and the rotating shaft 23 have a function as a rotating body.

  Although the four insertion pins 25 and the four guide pins 26 are provided at intervals of 90 degrees, for example, six may be provided every 60 degrees, and the number can be changed as necessary. Further, although the guide pin 26 guides the parts 5 so as to overlap each other, it is not always necessary depending on the shape of the parts.

  Then, the predetermined insertion pin 25 is positioned at the discharge end portion of the component extraction portion 8A of the chute 8, and the component 5 reaches the component extraction portion 8A while moving on the chute 8, The parts 5 dropped from the part take-out portion 8A are inserted into the insertion holes 5E formed in the rear wall 5C by the insertion pins 25, and are sequentially recovered by the recovery device 18 while being guided by the guide pins 26. It will be.

  In addition, a constant detection sensor 27 that is, for example, a light reflection type sensor that detects the component 5 when the component 5 passes through the component extraction portion 8A is disposed. In this case, every time the constant detection sensor 27 detects the component 5, when the counter 29 counts 10 as 1 increment, the control device 15 stops driving the vibration drive source of the vibrating body and shuts off the constant. The cylinder 17 is actuated to extend the rod so as to block the conveyance path to prevent the movement of the component 5 to the linear feeder 3, and the drive motor 19 of the recovery device 18 is driven to drive the rotating plate. 24 is controlled to rotate 90 degrees.

  The counter 29 is an addition counter, but may be a subtraction counter. In addition, this counter may be configured with software by creating a program.

  In this case, the recovery operation of the eleventh component 5 is stopped by stopping the driving of the vibration drive source of the vibrating body. However, by operating the constant cut-off cylinder 17, the linear feeder 3 is moved. By preventing the movement of the parts 5, the eleventh part 5 is not more reliably collected.

  In addition, although the said constant detection sensor 27 was provided as a constant detection apparatus, although this one sensor was provided, you may provide two or more. In the case of providing two or more, when at least one sensor detects, the counter 29 counts so as to detect one component 5.

  When the 90-degree intermittent rotation of the rotating plate 24 is finished, the control device 15 starts driving the vibration driving source of the vibrating body again and operates the constant cutoff cylinder 17 to contract the rod. The block of the movement of the component 5 to the linear feeder 3 is released.

  Therefore, as described above, since the parts 5 can be sequentially stored in the respective insertion pins 25 by the collection device 18, for example, ten pieces can be taken out from the collection device 18 by the operator. Thus, for example, it can be stored and stored in units of 10 in a transporter or a storage box. Then, the part 5 is taken out from the storage box or the like, and is welded and attached to the one part.

  As described above, according to the present embodiment, vibrations that can be conveniently transported and supplied while the parts are sequentially arranged and arranged in a predetermined posture, and can be stored and stored in units of a plurality of parts. A system component supply apparatus can be provided.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various alternatives described above without departing from the spirit of the present invention. It includes modifications or variations.
