More specifically, among the magnets 11a, 11b, and 11c, the magnet 11a has the weakest magnetic force, and therefore the magnet 11a has the weakest attracting force, and the magnet 11c has the strongest magnetic force, and thus the magnet 11c has the strongest attracting force. . The magnetic force of the magnet 11b is an intermediate magnetic force between the magnetic force of the magnet 11a and the magnetic force of the magnet 11c. Therefore, the attractive force of the magnet 11b is an intermediate attractive force between the attractive force of the magnet 11a and the attractive force of the magnet 11c. .

Of the magnets 11 a, 11 b, and 11 c, the magnet 11 a is disposed on the outermost side (outer peripheral side) in the radial direction of the rotating body 8, and the magnet 11 c is disposed closest to the center 8 a of the rotating body 8. The magnet 11b is disposed in the middle of the magnet 11a and the magnet 11c in the radial direction of the rotating body 8.
As described above, the magnet 11a and the magnet 11b are provided at portions where the distance from the rotation center (center 8a) of the rotating body 8 is different from each other.

  Similarly, the rotating body 8 is provided with a plurality of magnets 11 c intermittently (preferably at equal angular intervals) in the circumferential direction of the rotating body 8. Specifically, for example, four magnets 11c are arranged at intervals of 90 degrees. Each magnet 11c is arrange | positioned in the rotary body 8 in the site | part from which the distance from the center 8a is mutually equal.

  For example, the magnet 11a and the magnet 11b that are adjacent to each other are arranged in a direction that is shifted by 45 degrees from the center 8a. The magnet 11b and the magnet 11c which are adjacent to each other are arranged in a direction shifted by 45 degrees with respect to the center 8a. The magnet 11c and the magnet 11a which are adjacent to each other are arranged in a direction shifted by 45 degrees with respect to the center 8a.

  Here, among the magnets 11a, 11b, and 11c, the magnet 11a or the magnet 11b corresponds to the first magnet, and the magnet 11b or the magnet 11c corresponds to the second magnet.

The small parts attracted by the magnet 11a move along the movement locus 33a shown in FIG. However, the accessory component attracted by the magnet 11 a is captured by the capturing unit 12 when it reaches the capturing unit 12.
Further, the accessory component attracted by the magnet 11b moves along the movement locus 33b shown in FIG. 2 as the rotating body 8 rotates. However, the small parts attracted by the magnet 11 b are removed by a later-described withdrawal part 34 a or are captured by the capturing part 12 by reaching the capturing part 12.
Similarly, the small parts attracted by the magnet 11c move along the movement locus 33c shown in FIG. 2 as the rotating body 8 rotates. However, the small parts attracted by the magnet 11 c are either scraped off by a later-described scraping part 34 a or are captured by the capturing part 12 by reaching the capturing part 12.

The rotating body 8 is also provided with a magnet for stirring small parts (stirring magnet 16). By rotating the rotating body 8 with the stirring magnet 16 adsorbing the small parts, the small parts in the storage section 6 are stirred. That is, the fixed amount supply apparatus 100 further includes a stirring magnet 16 that is provided on the rotating body 8 and stirs the small parts in the storage unit 6 by adsorbing the small parts.
Here, the agitation magnet 16 includes a first agitation magnet 16a and a second agitation magnet 16b, which are provided at different locations from the rotation center (center 8a) of the rotating body 8, respectively. Yes. Thereby, the accessory parts in the storage part 6 are stirred more reliably.
Of the first stirring magnet 16a and the second stirring magnet 16b, the second stirring magnet 16b is arranged farther from the center 8a.
Both the first stirring magnet 16a and the second stirring magnet 16b are disposed closer to the center 8a than the magnet 11c disposed closest to the center 8a among the magnets 11a, 11b, and 11c. .

The bottom surface portion 15 of the storage portion 6 is inclined downward toward the wall surface 9a side, that is, the rotating body 8 side. More specifically, for example, the bottom surface portion 15 includes three inclined surfaces, a first inclined surface 15a, a second inclined surface 15b, and a third inclined surface 15c shown in FIG.
As shown in FIG. 3, the first inclined surface 15a is formed in a trapezoidal shape in plan view, and the lower bottom in the trapezoidal shape coincides with the inner surface of the front wall 2 in plan view, and the upper base is in plan view. In FIG. 4, it coincides with a part of the wall surface 9a (the central part in the left-right direction). The trapezoidal shape has a lower bottom longer than an upper bottom. The lower base of the trapezoid forms the front edge of the bottom surface portion 15, and the upper bottom of the trapezoid forms the part of the rear edge of the bottom surface 15 (the central portion in the left-right direction). The upper base of the trapezoidal shape extends horizontally in front of the lower end portion of the rotating body 8.
The second inclined surface 15b is formed in a right-angled triangle shape in plan view, and a right angle in the right-angled triangle shape is arranged in the back left, and one of the two sides sandwiching the right angle is a part of the side wall 3 in plan view ( The other side of the two sides sandwiching the right angle coincides with a part (left side part) of the wall surface 9a in plan view. One of the two sides sandwiching the right angle of the right triangle forms the left end edge of the bottom surface portion 15, and the other of the two sides sandwiching the right angle of the right triangle shape is a part of the rear end edge of the bottom surface portion 15 ( (Left side part). The hypotenuse in the right triangle shape coincides with one (left side) leg (hypotenuse) of the trapezoidal shape, and the second inclined surface 15b is inclined downward from the left side to the right side in FIG.
The third inclined surface 15c is formed in a right triangle shape in plan view, and the right angle in the right triangle shape is arranged in the right back, and one of the two sides sandwiching the right angle is a part of the side wall 4 in plan view ( The other side of the two sides sandwiching the right angle coincides with a part (right side part) of the wall surface 9a in plan view. One of the two sides sandwiching the right angle of the right triangle forms the right edge of the bottom surface 15, and the other of the two sides sandwiching the right angle of the right triangle is a part of the rear edge of the bottom surface 15 ( (Right part). The hypotenuse in the right triangle shape coincides with the other (right side) leg (hypotenuse) of the trapezoidal shape, and the third inclined surface 15c is inclined downward from the right side to the left side in FIG.
As described above, the first inclined surface 15a is formed in a trapezoidal shape in plan view. And the upper base of the said trapezoid shape is located ahead of the lower end of the rotary body 8 (for example, the said upper base is extended horizontally). For this reason, when the quantity of small parts in the storage unit 6 decreases, the small parts are gathered near the upper bottom by their own weight.

4 (a) and 4 (b) are views showing the capturing unit 12 and the roller 13 and the like provided in the quantitative supply device 100. FIG. 4 (a) is a perspective view and FIG. 4 (b) is a plan view. .
5A, 5B, and 5C are views showing the roller 13, in which (a) is a front view, (b) is a plan view, and (c) is a perspective view.
FIG. 6 is a schematic front view of the roller 13 and the scraping member 14.

As shown in FIGS. 4A and 4B, the capturing unit 12 is formed in a bowl shape that is inclined in one direction (specifically, for example, inclined from the left to the right). The bottom surface of the capturing unit 12 is formed in, for example, a V-groove shape or a U-groove shape. For this reason, the accessory parts captured by the capturing unit 12 are guided down to the downstream side (right side) of the capturing unit 12 by the bottom surface of the capturing unit 12 and approach the center in the width direction (front-rear direction) of the capturing unit 12. It comes to come.
Of the wall portions on the both sides in the width direction of the capturing portion 12 (the front wall portion and the back wall portion), the back wall portion is preferably constituted by a part of the wall surface 9a. You may be comprised by the plate-shaped part arrange | positioned at the front side.

The roller 13 has a cylindrical peripheral surface (outer peripheral surface), and is disposed at the downstream end of the capturing unit 12 such that the rotation axis AX2 extends horizontally and forward and backward. The end is closed. In other words, the left side portion of the peripheral surface of the roller 13 faces the inside of the capturing unit 12.
As shown in FIGS. 4 and 5, the roller 13 includes a cylindrical roller body 13 a and small parts embedded in the roller body 13 a so as to be exposed on the circumferential surface (outer circumferential surface) of the roller body 13 a. The roller magnet 18 to be attracted to the peripheral surface of the roller main body 13a, and the roller magnet 18 is inserted into the roller main body 13a from a portion different from the exposed portion of the roller magnet 18 on the peripheral surface of the roller main body 13a. And a fastening member 19 fastened to the head. The peripheral surface of the roller body 13 a is the peripheral surface of the roller 13.
More specifically, for example, the roller magnet 18 is formed in a rod shape and is inserted into the roller body 13a in a state of extending in the radial direction of the roller body 13a. One end is exposed at the center of the roller 13 in the width direction (front-rear direction). The central portion of the roller 13 in the width direction is aligned with the central portion of the capturing portion 12 in the width direction, that is, the deepest portion of the bottom surface of the V-shaped or U-shaped capturing portion 12.
The fixing member 19 is, for example, a male screw, and is fixed to the roller main body 13a by being screwed into a female screw formed on the roller main body 13a. That is, as shown in FIG. 5A, the axial direction of the fastening member 19 extends in a direction intersecting (for example, orthogonal to) the axial direction of the roller magnet 18. The roller magnet 18 is fixed to the roller main body 13a by abutting the tip portion of the roller magnet 18 against the circumferential surface of the roller magnet 18 or being inserted into the roller magnet 18 from the circumferential surface of the roller magnet 18. .
Therefore, the roller magnet 18 can be easily attached to and detached from the roller body 13a.

  Here, the fixed amount supply device 100 includes a plurality of roller magnets 18 having different attractive forces, and any one of the plurality of roller magnets 18 can be selectively attached to the roller body 13a. ing. That is, the optimum roller magnet 18 can be selectively used according to the weight of the small parts to be used.

When the small part is captured by the capturing unit 12, the roller 13 first functions as a stopper for stopping the small part flowing down on the capturing unit 12.
Then, when one end of the roller magnet 18 exposed on the circumferential surface of the roller 13 rotating clockwise reaches the position of the small component whose flow is restricted by the roller 13, the roller magnet 18 removes the small component. Adsorb. Depending on the rotational phase of the roller 13 when the small component reaches the roller 13, the flow-down of the small component by the roller 13 and the adsorption of the small component by the roller magnet 18 may be performed at the same time.
Even after the roller magnet 18 attracts the small component, the roller 13 further rotates clockwise, so that the small component is rotated and moved downstream along with the roller magnet 18. That is, the small parts adsorbed on the peripheral surface of the roller 13 move in an arc shape on the upper side of the roller 13 and are sent to the downstream side.
As described above, the fixed amount supply device 100 is arranged at the downstream end of the capturing unit 12 and rotates around the horizontal axis, and rotates in a state in which small parts captured by the capturing unit 12 are attracted to the peripheral surface. Thus, a roller 13 is provided for rotating the accessory part to the downstream side.

The small parts are scraped from the peripheral surface of the roller 13 by a scraping member 14 described below in the process of moving in an arc shape while being attracted to the peripheral surface of the roller 13.
As shown in FIG. 6, the scraping member 14 is disposed in, for example, a standing state (for example, a vertically standing state), and scrapes a small part from the peripheral surface of the roller 13. The flow guide part 14b connected to the lower end of 14a and arranged in an inclined state.
The scraping portion 14a is, for example, a plate-like member that is long in the front-rear direction. The flow-down guide part 14b is, for example, a plate-like member having a front-rear width equivalent to that of the scraping part 14a, and is inclined downward from the left side toward the right side.
Here, the scraping portion 14a is disposed below the horizontal plane HP1 including the rotation axis A2 of the roller 13 and upstream (left side) from the vertical plane VP1 including the downstream end EG1 (right end) of the roller 13. ing.
Accordingly, the small parts adsorbed on the peripheral surface of the roller 13 are scraped from the peripheral surface of the roller 13 at a position below the horizontal plane HP1 and upstream (left side) from the vertical plane VP1. .
Thus, the fixed amount supply apparatus 100 includes the scraping member 14 that scrapes small parts from the peripheral surface of the roller 13, and the scraping member 14 is below the horizontal plane HP1 including the rotation axis AX2 of the roller 13, and On the upstream side of the vertical surface VP1 including the downstream end of the roller 13, the small parts are scraped off from the peripheral surface.

  The small parts scraped off from the peripheral surface of the roller 13 by the scraping member 14 slide down along the inclined upper surface of the flow guide 14b. Here, as shown in FIGS. 2 and 3, the tray 10 (see FIGS. 1 to 3) is disposed below the downstream end of the flow guide portion 14 b, and slides along the flow guide portion 14 b. The fallen small parts are received by the tray 10.

The rotating body 8 and the roller 13 may be rotationally driven by a common actuator, or may be rotationally driven by separate actuators. In the present embodiment, it is assumed that the rotating body 8 and the roller 13 are rotationally driven by a motor 27 (FIG. 2) that is a common actuator.
Here, the rotation speed of the roller 13 is set to be higher than the rotation speed of the rotating body 8, for example. And is discharged onto the tray 10.

The fixed amount supply device 100 further includes a counting sensor 20 for counting the number of small parts discharged on the tray 10. The counting sensor 20 is, for example, a photoelectric sensor having a light emitting unit and a light receiving unit that are arranged to face each other.
The counting sensor 20 is disposed at a position where the small component can be detected in the process of moving in a circular arc shape above the roller 13, that is, at a position above the roller 13. Here, the small parts that are attracted to the roller 13 and moved in an arc shape are considered to be discharged onto the tray 10 through the scraping member 14.
The quantitative supply device 100 includes a control unit 28, and the counting sensor 20 outputs a detection signal to the control unit 28 every time a small component is detected. The control unit 28 counts the number of detection signals input from the counting sensor 20, and the count number is set to a predetermined number (for example, a number such as 5 or more and 10 or less; hereinafter, a predetermined number). When it reaches, a stop signal is output to the motor 27, and the motor 27 that has received the stop signal stops operating, whereby the rotation of the rotating body 8 and the roller 13 stops.
The control unit 28 outputs a stop signal to the motor 27 and outputs a notification signal to a notification unit such as a lamp (not shown) so that the notification unit that receives the notification signal performs a notification operation such as a light emitting operation. It has become.
By this notification operation, the operator can recognize that a predetermined number of small parts have been discharged on the tray 10.

As shown in FIG.1 and FIG.2, the saucer 10 is supported by the supporting member 24 which is a plate-shaped member of the L shape in front view, for example. The support member 24 has a first plate surface arranged horizontally and a second plate surface arranged in an upright state, and supports the tray 10 by the first plate surface. The support member 24 is disposed in a state in which the second plate surface rises upward from the left end portion of the first plate surface.
Here, for example, a take-out determination switch 25 for detecting take-out of small parts from the tray 10 is provided in the housing 1. The take-out determination switch 25 is disposed at a position facing the second plate surface of the support member 24, and a switch pressing portion 26 that is a protrusion for pressing the take-out determination switch 25 is provided on the second plate surface. Is provided. The switch pressing portion 26 can be configured by, for example, a bolt fixed to the second plate surface in a state of penetrating the second plate surface.
Further, a hinge 23 is provided on the side wall 4. The hinge 23 includes a fixing portion 23a fixed to the outer surface side of the side wall 4, and a rotating portion 23b that can rotate with respect to the fixing portion 23a. The axis of rotation of the rotating part 23b with respect to the fixed part 23a is a direction along the outer surface of the side wall 4 and also in the horizontal direction.
The upper end portion of the second plate surface of the support member 24 is fixed to the rotating portion 23b of the hinge 23.
The take-out determination switch 25 is normally turned on by being pressed by the switch pressing portion 26 by the weight of the tray 10 and the support member 24.
When the small parts discharged on the saucer 10 are picked up from the saucer 10 by the operator's hand, the saucer 10 is pulled rightward in FIG. 2, so that the rotating portion 23b, the support member 24, and the saucer 10 are moved. The switch pressing portion 26 is lifted from the take-out determination switch 25 by rotating with respect to the fixing portion 23a. As a result, the take-out determination switch 25 is temporarily turned off.
The control unit 28 monitors the state of the take-out determination switch 25, and again after a predetermined time (for example, 2 seconds) from the timing when the take-out determination switch 25 switches from the on state to the off state. The rotational drive of the rotating body 8 and the roller 13 by the motor 27 is started, that is, the discharge operation of the small parts is resumed.
Thus, the discharging operation of the predetermined number of small parts from the storage unit 6 to the tray 10, the stopping operation of the rotating body 8 and the roller 13, the notification operation by the notification unit, and the predetermined number of small components from the tray 10 by the operator. The take-out operation can be repeatedly executed.

As shown in FIGS. 2 and 3, the tray 10 is connected to the hemispherical (lower half shape of the sphere) main body 10 a and the upper side of the main body 10 a and is gentler than the upper end of the main body 10 a. And an upper edge enlarged-diameter portion 10b that is expanded outward by an inclination.
The saucer 10 having such a shape can be produced by subjecting a metal plate to a spatula drawing process.
Since the saucer 10 has such a shape, the operator can take out all the small parts on the saucer 10 with one hand without difficulty.

Furthermore, the fixed amount supply apparatus 100 includes a raising portion 17 that can raise the lower end of the small parts attracted by the magnets 11a, 11b, and 11c in front of the capturing portion 12.
The rising portion 17 is, for example, a bent plate-like member, and protrudes leftward from the upper left end of the capturing portion 12. The left portion of the rising portion 17 is inclined upward toward the right side, and the right portion of the rising portion 17 is inclined downward toward the right side.
When the accessory part attracted by the magnets 11a, 11b, and 11c hangs down from the magnets 11a, 11b, and 11c, when the accessory part goes to the capturing part 12, the lower end part of the accessory part is the left end part of the capturing part 12 The small parts may fall into the storage unit 6 before being captured by the capturing unit 12.
For such a situation, by providing the rising portion 17, the lower end of the small parts hanging from the magnets 11 a, 11 b, and 11 c can be gradually raised along the rising portion 17 and guided to the capturing portion 12 side. it can. Therefore, it is possible to suppress the small parts from being caught by the capturing unit 12 and falling without being captured by the capturing unit 12.

As shown in FIGS. 1 to 3, the fixed amount supply device 100 includes a payout mechanism 35 for selectively paying off small parts attracted by the magnets 11 a, 11 b, or 11 c.
The payout mechanism 35 includes a fixed member 22, a first movable member 34, and a second movable member 21 described below.

As shown in FIG. 7A, the fixing member 22 is formed in a plate shape such as a rectangular shape, for example. As shown in FIG. 1, the fixing member 22 is fixed to the wall surface 9 a in a state where the plate surface of the fixing member 22 stands up (for example, upright) with respect to the wall surface 9 a of the partition wall 9. In FIG. 7A, the lower side is the wall surface 9 a side, the left side is the radially outer side of the rotating body 8, and the right side is the radially inner side of the rotating body 8. The fixing member 22 includes, for example, an insertion fixing portion 22b, and is fixed to the wall surface 9a by welding or the like in a state where the insertion fixing portion 22b is inserted into a recess (not shown) formed on the wall surface 9a. Has been.
The plate surface of the fixing member 22 is arranged along the radial direction of the rotating body 8, for example.
As shown in FIG. 7A, for example, a pair of long holes 22 a are formed in the fixing member 22 as fixing holes for fixing the first movable member 34 to the fixing member 22. The pair of long holes 22a extend along the radial direction of the rotating body 8, and are arranged side by side in the radial direction.

As shown in FIG. 7B, the first movable member 34 is formed in a plate shape such as a rectangular shape, for example. The first movable member 34 is disposed along one plate surface of the fixed member 22 and is fixed to the fixed member 22. In FIG. 7B, the lower side is the wall surface 9 a side, the left side is the radially outer side of the rotating body 8, and the right side is the radially inner side of the rotating body 8.
The first movable member 34 includes, for example, a plurality of lower fixed holes 34 d for fixing the first movable member 34 to the fixed member 22, and the second movable member 21 with respect to the first movable member 34. A plurality of upper fixing holes 34c for fixing are formed.
The first movable member 34 selects a small part adsorbed by the second magnet out of the first magnet (magnet 11a or 11b) and the second magnet (magnet 11b or 11c) before being captured by the capturing unit 12. It is provided with a payout part 34a for paying off. The payout part 34a is arranged on the movement path of the small parts attracted by the second magnet (magnet 11b or 11c) (see FIGS. 8 and 9). The payout part 34a is disposed along the wall surface 9a.
The payout portion 34a has a payout surface 34b which is one plate surface of the payout portion 34a. The scraping surface 34b is a surface for scraping small parts adsorbed by the second magnet.

As shown in FIG.7 (c), the 2nd movable member 21 is formed in plate-shaped shapes, such as L shape, for example. The second movable member 21 is disposed on the same plane as the fixed member 22 and is fixed to the first movable member 34. In FIG. 7C, the lower side is the wall surface 9 a side, the left side is the radially outer side of the rotating body 8, and the right side is the radially inner side of the rotating body 8.
The second movable member 21 includes a fixed portion 21 a that is fixed to the first movable member 34. For example, a pair of elongated holes 21d is formed in the fixed portion 21a as a fixing hole for fixing the second movable member 21 to the first movable member 34. The pair of long holes 21d extend along the radial direction of the rotating body 8, and are arranged side by side in the radial direction.
In the second movable member 21, a notch-shaped portion 21 c for forming a gap 35 a for allowing small parts to pass therethrough is formed on the wall surface at a portion extending to the left in FIG. 7C from the fixed portion 21 a. It is formed on the 9a side. Furthermore, in the 2nd movable member 21, the part of the left side in FIG.7 (c) rather than the notch shape part 21c is the 2nd drop-off part 21b. The second payout portion 21b is disposed along the wall surface 9a.

As shown in FIG. 7 (d), by fixing the lower fixing hole 34d of the first movable member 34 to each of the pair of long holes 22a of the fixing member 22 by using fastening members 29 such as bolts, A first movable member 34 is fixed to the fixed member 22.
Further, by fixing the pair of long holes 21d of the second movable member 21 to the upper fixed holes 34c of the first movable member 34 using the fastening members 36 such as bolts, the first movable member 34 is fixed. On the other hand, the second movable member 21 is fixed.
Thus, the fixed member 22, the 1st movable member 34, and the 2nd movable member 21 are assembled | attached mutually, and the pay-off mechanism 35 is comprised. Since the fixed member 22 is fixed to the wall surface 9a, the first movable member 34 is fixed to the wall surface 9a via the fixed member 22. The second movable member 21 is fixed to the fixed member 22 via the first movable member 34, and by extension is fixed to the wall surface 9 a via the fixed member 22.

  The first movable member 34 is detachable from the fixed member 22, that is, detachable from the partition wall 9. Similarly, the second movable member 21 can be attached to and detached from the first movable member 34, that is, can be attached to and detached from the fixed member 22 (and consequently to the partition wall 9).

Here, the fixing position of the fastening member 29 with respect to the long hole 22a can be adjusted in the longitudinal direction of the long hole 22a. Moreover, it can be changed which lower stage fixing hole 34d is fixed to the long hole 22a. Therefore, the relative position of the first movable member 34 with respect to the fixed member 22 can be changed in the left-right direction of FIG. 7D (that is, the radial direction of the rotating body 8). That is, the first movable member 34 including the pay-off portion 34 a is arranged along the radial direction of the rotating body 8 and is variable in position in the radial direction of the rotating body 8. The arrangement and the number of the lower fixing holes 34d may be set as appropriate according to the required adjustment range (the adjustment range of the position of the first movable member 34 with respect to the fixed member 22).
The fixing position of the fastening member 36 with respect to the long hole 21d can be adjusted in the longitudinal direction of the long hole 21d. Moreover, it can be changed with respect to which upper stage fixing hole 34c the long hole 21d is fixed. Therefore, the relative position of the second movable member 21 with respect to the first movable member 34 can be changed in the left-right direction of FIG. 7D (that is, the radial direction of the rotating body 8). That is, the second movable member 21 including the second payout portion 21b is disposed along the radial direction of the rotating body 8 and is variable in position in the radial direction of the rotating body 8 (position relative to the first movable member 34). The position is variable with respect to the fixing member 22. The arrangement and number of the upper fixing holes 34c may be set as appropriate according to the required adjustment range (the adjustment range of the position of the second movable member 21 relative to the first movable member 34).
Here, the fixed portion 21 a of the second movable member 21 is disposed in an upper stage of the fixed member 22 (a position farther from the wall surface 9 a than the fixed member 22) in contact with the fixed member 22. Therefore, when the second movable member 21 is moved relative to the fixed member 22, the second movable member 21 moves in the left-right direction in FIG. 7D while the fixed portion 21 a is guided by the fixed member 22. Move to.

Here, the second payout portion 21b is arranged to the left in FIG. 7D, that is, farther from the rotation center of the rotating body 8 than the payout portion 34a. Therefore, in the state where the fixed member 22, the first movable member 34, and the second movable member 21 are assembled, a gap (the gap for allowing small parts to pass between the payout portion 34a and the second payout portion 21b ( Gate) 35a is formed.
Here, since the position of the second movable member 21 with respect to the first movable member 34 can be adjusted, the width of the gap 35a can be adjusted in the left-right direction of FIG.

  8 (a), (b), (c), FIGS. 9 (a), (b), (c), and FIGS. 10 (a), (b), (c), the payout portion 34a FIG. 2 is an explanatory diagram of the dropping mechanism 35 including the like, and shows a state where the dropping mechanism 35 is viewed in the direction of arrow A in FIG.

As shown in FIG. 2, the payout portion 34 a is disposed so that the payout surface 34 b, which is one plate surface, faces obliquely downward. Small parts that are attracted by the second magnet and rotate together with the rotating body 8 are scraped off by contacting the scraping surface 34b. The payout surface 34b may be arranged vertically downward.
As described above, the payout portion 34a has the payout surface 34b arranged obliquely downward or downward, and the small parts adsorbed by the second magnet come into contact with the payout surface 34b, so that the small parts are removed. Dispel.

As shown in each figure of Drawing 8, Drawing 9, and Drawing 10, magnet 11a, 11b, and 11c are formed in the shape of a rod, for example. The magnets 11a, 11b, and 11c are inserted into slide holes 31a, 31b, and 31c formed on the surface of the rotating body 8 on the partition wall 9 side, respectively. Each axis of the slide holes 31a, 31b, 31c extends in a direction perpendicular to the plate surface of the rotating body 8. The slide holes 31a, 31b, 31c have an inner diameter slightly larger than the outer diameter of the corresponding magnets 11a, 11b, 11c. The magnets 11a, 11b, and 11c are arranged so that their respective axes are aligned with the corresponding slide holes 31a, 31b, and 31c, and are slidable along the corresponding slide holes 31a, 31b, and 31c. Yes.
That is, the 1st magnet and the 2nd magnet are hold | maintained at the rotary body 8 so that it can project and retract toward the wall part side from the wall (partition wall 9) side surface in the rotary body 8. FIG.
A slight gap 32 is formed between the rotating body 8 and the partition wall 9.
The magnets 11 a, 11 b, and 11 c are protruded from the rotating body 8 by attracting with small parts and are in close contact with the partition wall 9.
Thus, since each magnet 11a, 11b, and 11c can project and retract, the clearance 32 is provided between the rotary body 8 and the partition wall 9, and the friction between the rotary body 8 and the partition wall 9 is reduced. Even so, each of the magnets 11a, 11b, and 11c can be brought into contact with the partition wall 9 to attract small parts.

  The stirrer magnets 16 (first stirrer magnet 16a, stirrer magnet 16b) are also similar to the magnets 11a, 11b, and 11c from the wall (partition wall 9) side surface to the wall in the rotating body 8. It is preferable that the rotating body 8 is held so as to be able to project and retract toward the part side.

Next, the operation will be described.
As the small parts, any one of the three types of screws 7a, 7b, and 7c is stored in the storage unit 6 and the fixed supply device 100 is used.

First, the case where the smallest screw 7a among the three types of screws 7a, 7b and 7c is used will be described.
In this case, as shown in FIGS. 8A and 8B, the magnet 11a passes through the position corresponding to the gap 35a (see FIG. 8A), while the magnets 11b and 11c pass through the position corresponding to the pay-off portion 34a. As shown (see FIGS. 8B and 8C), the position of the first movable member 34 with respect to the fixed member 22 is adjusted.
As an example, the width of the gap 35a is set to a small width in accordance with the size of the screw 7a. That is, the position of the second movable member 21 with respect to the first movable member 34 is adjusted so that the width of the gap 35a is reduced.
8, the screw 7 a attracted by the magnet 11 a selectively passes through the gap 35 a (FIG. 8 (a)), while the screw 7 a attracted by the magnet 11 b and the magnet 11 c is a drop-off portion. 34a (see FIGS. 8B and 8C).
Therefore, since the screws 7a can be conveyed to the capturing unit 12 one by one, the screws 7a can be more reliably detected by the counting sensor 20 one by one.

Next, the case where the medium size screw 7b is used among the three types of screws 7a, 7b, and 7c will be described.
In this case, as shown in FIGS. 9A and 9B, the magnet 11a and the magnet 11b pass through a position corresponding to the gap 35a (see FIGS. 9A and 9B), while the magnet 11c is connected to the scraping portion 34a. The position of the first movable member 34 with respect to the fixed member 22 is adjusted so as to pass through the corresponding position (see FIG. 9C).
As an example, the width of the gap 35a is set to a medium width (wider than that in FIG. 8) according to the size of the screw 7b. That is, the position of the second movable member 21 with respect to the first movable member 34 is adjusted so that the width of the gap 35a is medium.
Here, the magnetic force of the magnet 11a is set so that the medium-sized screw 7b cannot be attracted by the magnetic force of the magnet 11a. For this reason, as shown to Fig.9 (a), the magnet 11a passes the position corresponding to the clearance gap 35a, without adsorb | sucking the screw 7b.
Further, the screw 7b adsorbed by the magnet 11b selectively passes through the gap 35a (FIG. 9B), while the screw 7b adsorbed by the magnet 11c is removed by the withdrawal portion 34a (FIG. 9 ( c)).
Therefore, since the screws 7b can be conveyed to the capturing unit 12 one by one, the screws 7b can be detected by the counting sensor 20 one by one with more certainty.

Next, a case where the largest screw 7c among the three types of screws 7a, 7b, and 7c is used will be described.
In this case, as shown in FIGS. 10A and 10B, the magnet 11a, the magnet 11b, and the magnet 11c are fixed so as to pass through positions corresponding to the gap 35a (see FIGS. 10A, 10B, and 10C). The position of the first movable member 34 with respect to the member 22 is adjusted.
As an example, the width of the gap 35a is set to a large width (wider than that in FIG. 9) in accordance with the size of the screw 7c. That is, the position of the second movable member 21 with respect to the first movable member 34 is adjusted so that the width of the gap 35a is increased.
Here, the magnetic force of the magnets 11a and 11b is set so that the large screw 7c cannot be attracted by the magnetic force of the magnets 11a and 11b. For this reason, as shown in FIGS. 10A and 10B, the magnets 11a and 11b pass through positions corresponding to the gaps 35a without attracting the screws 7c.
On the other hand, the screw 7c adsorbed by the magnet 11c passes through the gap 35a (FIG. 10C).
Here, even when the screw 7c interferes with the scraping portion 34a or the second scraping portion 21b, such as when the longitudinal dimension of the screw 7c is larger than the width of the gap 35a, the screw 7c is It can rotate while adsorbed by 11c and pass through the gap 35a.
In the case of FIG. 10 as well, since the screws 7c can be conveyed to the capturing unit 12 one by one, the screws 7c can be detected by the counting sensor 20 one by one more reliably.

Here, in the position shown in FIG. 8, the drop-off part 34a of the first movable member 34 wipes out the small part attracted by the magnet 11b, but in the position shown in FIG. 9, the small part attracted by the magnet 11b. Pass through. That is, the payout part 34a is a position where the small part attracted by the second magnet (in this case, the magnet 11b) is on the movement path (FIG. 7) and a position avoiding the movement path. The position is variable between the retracted position (FIG. 8).
Similarly, in the position shown in FIG. 8 and FIG. 9, the pay-off unit 34a wipes out small parts attracted by the magnet 11c, but passes the small parts attracted by the magnet 11c in the position shown in FIG. . That is, the pay-off unit 34a avoids the pay-off position (FIGS. 8 and 9), which is the position on the movement path of the small parts attracted by the second magnet (in this case, the magnet 11c), and the movement path. The position is variable to the retracted position (FIG. 10).

According to the embodiment as described above, the fixed amount supply device 100 is provided with the first magnet that is provided on the rotating body 8 and moves the accessory parts along with the rotation of the rotating body 8 by adsorbing the accessory parts. In the body 8, the first magnet is provided at a part different in distance from the rotation center of the rotating body 8, and the accessory part is attracted by the rotating force of the rotating body 8 by attracting the accessory part with a stronger attracting force than the first magnet. The second magnet to be moved, the capture unit 12 that captures the small parts adsorbed by the first magnet or the second magnet, and the small part adsorbed by the second magnet is selected before being captured by the capture unit 12 And a payout part 34a for paying off automatically.
Therefore, even when the same quantitative supply apparatus 100 is also used for quantitative supply of a plurality of types of small parts (for example, screws 7a, 7b, 7c), quantitative supply with high reproducibility becomes easy.

  In addition, since the payout unit 34a is variable in position between a payout position that is a position on the movement path of the small parts attracted by the second magnet and a retreat position that is a position that avoids the movement path, By using the common pay-off unit 34a, it is possible to switch between a state where the small parts attracted by the second magnet are to be dropped and a state where no pay-off is performed.

  Since the payout part 34a is arranged along the radial direction of the rotating body 8, small parts can be reliably dropped off by the payout part 34a. In addition, since the position of the payout portion 34a is variable in the radial direction of the rotating body 8, the payout portion 34a can be moved to the payout position and the retracted position by moving the dropout portion 34a by as little distance as possible.

  The fixed amount supply device 100 further includes a second payout unit 21b disposed farther from the rotation center of the rotating body 8 than the payout unit 34a, and between the payout unit 34a and the second payout unit 21b. Is formed with a gap 35a through which a small part adsorbed by the first magnet passes. The position of the second payout portion 21b is variable with respect to the payout portion 34a so that the width of the gap 35a can be adjusted. Therefore, not only the payout portion 34a but also the second payout portion 21b allows the small parts to be removed as necessary, and the width of the gap 35a is appropriately adjusted according to the size of the small parts. be able to.

  Further, the payout portion 34a has a payout surface 34b disposed obliquely downward or downward, and the small parts attracted by the second magnet come into contact with the payout surface 34b, thereby dropping the small parts. . Therefore, the payout part 34a can more reliably pay off small parts.

  Further, since the rotating body 8 is disposed on the opposite side of the storage section 6 with the wall portion (partition wall 9) of the storage section 6 interposed therebetween, small parts are worn by contact with the rotating body 8. There is no end. Therefore, small parts can be quantitatively supplied with higher reproducibility. Further, since the wear of the rotating body 8 due to contact with small parts can be suppressed, the durability of the quantitative supply device 100 is improved.

  The scraping member 14 is a small component from the peripheral surface of the roller 13 below the horizontal plane HP1 including the rotation axis AX2 of the roller 13 and upstream of the vertical surface VP1 including the downstream end EG1 of the roller 13. Therefore, it is possible to suppress biting of small parts between the roller 13 and the scraping member 14.

<Modification>
FIG. 11 is a view showing a roller 13 provided in a small component supply device according to a modification. Among these, (a) is a front view, and (b) is a view of the roller 13 viewed from the direction of arrow B in (a).
The quantitative supply device for small parts according to this modified example is different from the quantitative supply device 100 according to the above-described embodiment in the points described below, and is otherwise different from the quantitative supply device 100 according to the above-described embodiment. It is constituted similarly.

In the case of this modification, the roller 13 is provided with a position correction mechanism for correcting the position of the end of the small component that has flowed down the capture unit 12 to a position that can be attracted by the roller magnet 18.
As this position correction mechanism, for example, one or more dimples (dents) are formed on the outer peripheral surface of the roller body 13a. As an example, three dimples 37a, 37b, and 37c are formed at different portions in the circumferential direction of the roller body 13a. The shape of the dimples 37a, 37b, and 37c is not particularly limited. For example, the dimples 37a, 37b, and 37c can be formed in a conical shape that is reduced in diameter toward the deeper portions of the dimples 37a, 37b, and 37c.
As shown in FIG. 11B, the dimples 37a, 37b, and 37c are offset from the portion corresponding to the deepest portion of the bottom surface of the V-shaped or U-shaped capturing portion 12 on the outer peripheral surface of the roller body 13a. Is arranged. That is, the dimples 37 a, 37 b, and 37 c are disposed at portions that are offset from the central portion in the width direction (front-rear direction) of the roller 13.
Of the dimples 37 a, 37 b, and 37 c, the dimple 37 a is arranged offset to one side in the width direction of the roller 13 (leftward in FIG. 11B), and the dimples 37 b and 37 c are arranged in the width direction of the roller 13. Are offset to the other side (rightward in FIG. 11B).

As described above, the plurality of dimples 37 a, 37 b, and 37 c are formed in the roller 13 in a staggered arrangement in the width direction of the roller 13. When the position is not aligned with the central portion in the direction, the lower end of the accessory part is flipped up by any dimple. That is, until the lower end of the accessory part is aligned with the central portion in the width direction of the roller 13, the operation of raising the lower end of the accessory part is repeatedly performed.
Therefore, the small parts that have flowed down the capturing portion 12 can be reliably attracted one by one by the roller magnet 18 of the roller 13 and rotated downstream to be supplied (discharged) onto the tray 10. In other words, the small parts that have flowed down the capture unit 12 can be more reliably discharged, and the small parts that have flowed down the capture unit 12 can be more reliably discharged one by one.

Here, in FIG. 11B, the right side is the rear (back side), and the left side is the front (front side). That is, more dimples are arranged on the rear side, that is, on the rotating body 8 side holding the magnets 11a, 11b, and 11c.
Since it is considered that the head of the screw 7 is often attracted by the magnets 11a, 11b, and 11c, it is considered that the head of the screw 7 that has flowed down the capturing portion 12 is also located on the rotating body 8 side. However, since more dimples are arranged on the rotating body 8 side, it can be expected that position correction by dimples can be performed more quickly.

Here, the dimple formed on the outer peripheral surface of the roller main body 13a is exemplified as the position correction mechanism, but the portion offset from the portion corresponding to the deepest portion of the bottom surface of the capturing portion 12 on the outer peripheral surface of the roller main body 13a. In addition, the same effect can be obtained even if a groove such as a protrusion or a spiral is formed instead of the dimple.
However, when dimples or grooves are provided as the position correction mechanism, even if the roller 13 and the scraping portion 14a of the scraping member 14 are arranged close to each other, interference between the position correction mechanism and the scraping portion 14a is suppressed. The advantage that you can do it.

  As mentioned above, although embodiment and the modification were demonstrated with reference to drawings, these are illustrations of this invention and can also employ | adopt various structures other than the above.

  For example, the pay-off mechanism 35 does not necessarily have to include the second movable member 21. Accordingly, the payout mechanism 35 does not necessarily include the gap 35a and the second payout portion 21b.

  Further, in the above description, it is assumed that the weight of the accessory part increases as the size of the accessory part (longitudinal dimension) increases. However, the size and weight of small parts may not have a positive correlation. Therefore, it is not always necessary to increase the width of the gap 35a as the weight of the small component increases. The width of the gap 35a may be set as appropriate according to the size of the small part, not the weight of the small part.
