Description

Parts storage case for bulk feeder {BULK FEEDER PARTS HOLDING CASE}

The present invention relates to a component feeder case for a bulk feeder, which is detachably installed and used in a feeder main body.

In patent document 1 and patent document 2, the structural example of a bulk feeder is disclosed. Specifically, a storage chamber including a rear wall surface and an arcuate guide surface of the outer circumference, a blower provided at an upper end of the guide surface, a passage provided downstream from the blower, and a tip of the passage. A bulk feeder is provided having a component separating portion provided in the upper portion, a rotating plate provided behind the wall surface of the storage chamber, and a plurality of magnets provided in the rotating plate.

The bulk feeder rotates the rotating plate in a predetermined direction in a state in which the parts are stored in a single state (a state in which the direction is not constant) in the storage chamber, thereby rotating the parts in the storage chamber by the magnetic force of the magnet to the wall surface and the arc-shaped guide. By simultaneously sucking on both sides of the face and aligning them along both sides, only the aligned parts are introduced into the inlet, and the components introduced into the inlet are self-weighted to the component separation unit through the passage. It has a function of supplying a part to an outlet corresponding to a part formed in the part separating part.

In the bulk feeder disclosed in Patent Documents 1 and 2, the rotating plate and the motor are provided in the main body case, and only the inlet, the passage, and the outlet corresponding to the specific parts (parts of the same size and shape) are designated. Since the structure has corresponding dimensions and shapes, parts other than a specific type cannot be used as the supply target. The bulk feeder of the past is similar to the bulk feeder disclosed in Patent Literatures 1 and 2, and since it is a structure in which only a specific kind of component is supplied, components other than the specific kind cannot be used as a supply target.

By the way, the bulk feeder (including the bulk feeder disclosed by patent document 1 and patent document 2) which supplies the components accommodated in the state contained in the storage chamber in the predetermined direction to the ejection opening is a component supply means of a mounter (part mounting apparatus). Its use value is extremely high. In a mounter using this kind of bulk feeder as a part supply means, a plurality of bulk feeders capable of supplying different kinds of parts are provided in the feeder mounting stand, and a component selectively extracted from the plurality of bulk feeders is a circuit board or the like. Mounted on the mounted object.

This mounter repeats the operation of selectively taking out parts to be mounted on the mounted object from a plurality of bulk feeders,

When the parts to be mounted must be changed during the operation of the parts replenishment work (the work of replenishing the parts in the bulk feeder's storage compartment with the small number of parts remaining),

· Part change operations (change of parts available from each bulk feeder to other types of parts) must be carried out.

Usually, the above-mentioned "part replacement work",

Method (M1): A method of replenishing parts in a storage compartment of the bulk feeder without removing the bulk feeder with the small number of parts remaining from the feeder mounting stand.

Method (M2): performed by a method of separating a bulk feeder having a small number of parts remaining from the feeder mounting stand, replenishing the parts in the storage compartment of the bulk feeder, and installing the bulk feeder after the part replenishment on the feeder mounting stand,

The "part change operation" mentioned above,

Method M3: This is performed by separating the bulk feeder, which has become unnecessary, from the feeder mount, and then installing a separate bulk feeder on which the feeder mount can supply different types of parts.

However, in the methods M1 and M2 according to the above-mentioned parts replenishment work, parts stored in a package such as a bag or a container must be replenished directly in the storage compartment of the bulk feeder. In addition to the disadvantage of being caught, there is a disadvantage for the non-skilled person to flow out parts during work. In addition, in the method M3 according to the above-mentioned "part change operation," it is necessary to prepare and store a plurality of bulk feeders for part change in advance, and in addition to the disadvantage that a storage space corresponding thereto is required. There is a disadvantage that the maintenance of the bulk feeder for component change is indispensable.

To remedy these shortcomings,

The bulk feeder is constructed from a feeder body and a component storage case detachable to the feeder body

Part of the essential elements after the bulk feeder original function (the function of supplying parts stored in a single state in the storage chamber to the outlet in a predetermined direction) is a non-common element that varies depending on the size and shape of the part. There is a need for a bulk feeder that satisfies the basic concept of being installed in the case and having a common element provided in the feeder main body, which is not changed by the size and shape of the part. That is, when such a bulk feeder is realized, the desired parts replacement work and part change work can be performed simply by replacing only the parts storage case, and the original function of the bulk feeder can be exhibited even after replacement. It becomes possible.

1. Japanese Patent No. 3442324 2. Japanese Patent No. 3796971

An object of the present invention is to accommodate parts for bulk feeders that can accurately perform the desired parts replacement work and change parts work by simple replacement work, and can exhibit the original functions of the bulk feeder even after replacement. Is to provide a case.

In order to achieve the above object, the present invention is a bulk feeder component storage case detachable to a feeder body having a plurality of permanent magnets are arranged at intervals along a predetermined arc orbit, the component storage case, A storage chamber for storing a plurality of parts which can be sucked by magnetic force in a single state; A circular arc-shaped guide is provided on the inner surface of the side wall of the storage compartment from the bottom to the upper side along a predetermined arc track, and moves the component in the storage chamber in a predetermined direction and moves upward in the same direction. ); It is installed from the bottom to the top, starting from the upper end of the guide, along a predetermined arc orbit, and moving a part in a predetermined direction to move the inside of the guide through a mouth, and moving upward in the same direction. An arc-shaped supply passage for discharging; And an ejection opening of an upper surface opening which is provided at the front end of the supply passage and moves out of the supply passage and draws out a component in a predetermined direction supplied to the front end to the outside. Is used by being installed in the feeder main body so that the guide and the supply passage face the permanent magnet which is movable under a predetermined arc orbit, and the supply passage is an arc hole provided on the inner surface of the side wall of the storage chamber. It is formed by the part which closed the upper part of the opening of viii, and the said guide tool is formed by the part which the opening of the said circular arc tool is not blocked.

When the rotating member is rotated in a state in which a component storage case in which a plurality of components are stored in a single state (a state in which the direction is not fixed) is installed in the feeder main body, the permanent magnet of the rotating member guides the component storage case under a predetermined circular arc orbit. Move in the direction facing the sphere and supply passage. By the movement of the permanent magnet, the components in the storage chamber are accommodated in the guides in a predetermined direction, and the components of the predetermined direction moving upward in the guides are blown into the supply passage through the air inlet, and the inside of the supply passage. The component in the predetermined direction for moving upwards is supplied to the outlet.

Since the component storage case includes a non-common element that varies with the size and shape of the component, and the component storage case is detachable to a feeder body including a common element that does not change with the size and shape of the component, Even if the component storage case provided in the feeder main body is replaced with another component storage case, the same component supply operation as before replacement can be realized regardless of the type of component. That is, by simply replacing the parts storage case, the desired "parts replacement work" and "parts change operation" can be performed accurately, and the original function of the bulk feeder can be exhibited without interruption even after replacement.

In short, the component storage case does not require much storage space in addition to taking on the role of a package in which components are stored, and thus special maintenance is unnecessary at the time of storage. Previous disadvantages, ie,

Taking time to replenish parts

· Spilling of parts outside during replenishment

· Prepare and store multiple bulk feeders for changing parts beforehand to carry out the parts changing work (requires corresponding storage space)

· It is possible to reliably eliminate the necessity of maintenance of the part change bulk feeder stored in order to perform the part change work, and to reduce the detachment as a whole.

In addition, since the replacement parts storage case can be reused, when the replacement parts storage case is recovered and the parts are replenished, the resource savings can be achieved by reusing the replacement parts storage case as the replacement parts storage case. .

According to the present invention, it is possible to accurately perform the desired "part replacement operation" and "part change operation" by a simple replacement operation of the parts storage case, and can exhibit the original function of the bulk feeder without any trouble even after replacement.

Moreover, when each 1st leaf spring 21f and each 2nd leaf spring 21g are provided with the component storage case 10 in case mounting part MS, the three-dimensional position of the annoying component storage case 10 is shown. It plays the role of determining.

As shown in Figs. 9A and 9B, the rotor 22 includes a disc-shaped rotor body 22a, a radial type ball bearing 22b, and a total of eight permanent magnets. (22c) is included.

The rotor main body 22a includes a ring-shaped opening 22a1 provided in the outer periphery of the seat surface, and a bearing mounting hole 22a2 provided in the center, and the magnetic force of the permanent magnet is permeable. It is formed of metal or plastic such as aluminum. The left and right dimensions of the rotor body 22a are slightly smaller than the depth of the rotor arrangement recess 21c1 of the frame 21. Moreover, on the outer peripheral surface of the rotor main body 22a, the flat outer peripheral tooth 22a3 which performs the role of a driven gear is formed.

The ball bearing 22b includes an outer ring and an inner ring, and is attached to the rotor body 22a by inserting the outer ring into the bearing mounting hole 22a2 using an adhesive if necessary. In the center of the ball bearing 22b provided in the rotor main body 22a, the axial hole 22b1 (1) by the inner hole of an inner ring exists.

A total of eight permanent magnets 22c form a cylindrical or quadrangular column shape having magnetic poles on both end faces, while the magnetic pole corresponds to the center of the rotor body 22a (the rotation center of the rotor 22). ] And concentric virtual circles (VC) at 45 ° intervals. Each permanent magnet 22c applies an adhesive to a hole of a predetermined depth formed in the left face of the ring-shaped elongated portion 22a1 so that one magnetic pole is exposed in a state substantially flush with the left face of the ring-shaped elongated portion 22a1. It is installed by taking in and using.

In addition, the center of one magnetic pole of each permanent magnet 22c (corresponding to the center of magnetic force where the magnetic field lines are most concentrated) is located on the virtual circle VC. The radius of curvature of the virtual circle VC (= radius of curvature of the circular orbit) is the outer circular arc surface (12) of the circular arc sphere 12b constituting the guide port 15 and the supply passage 16 of the component storage case 10. It is set to satisfy the condition of the radius of curvature of 12b1) or less and the condition of the radius of curvature of the inner arc surface 12b2 or more.

Moreover, the thing which has sufficient surface magnetic force is used for each permanent magnet 22c also in order to attract the component in the storage chamber 14 to the guide opening 15 direction. The polarity of one pole of each permanent magnet 22c may be either the N pole or the S pole, or the N pole and the S pole may be alternately arranged along the virtual circle VC.

As shown in Figs. 8A and 8B, the rotor 22 is inserted into the rotor arranging recess 22c1 of the frame 21 so that its left side faces the left side. The support shaft SS is inserted into the bearing hole 22b1 of the bearing 22b, and the screw part of the support shaft SS is screwed into the screw hole 22b1 to allow the rotor 22 to rotate in the recess 22c1. Is arranged. The support shaft SS includes a circular head, a cylinder, and a threaded portion integrally. The left and right dimensions of the cylindrical portion are substantially the same as the left and right dimensions of the shaft hole 22b1. 22 may rotate in a state where the seat surface is parallel to or close to the seat surface of the rotor disposition portion 21c. In addition, since the left and right dimensions of the rotor main body 22a are slightly smaller than the depth of the rotor arranging recess 22c1, the seating surface of the ring-shaped elongated portion 22a1 is slightly smaller to the right than the left opening of the rotor arranging recess 22c1. I'm in.

The rotor drive mechanism (not shown) is for rotating and stopping the rotor 22 in a predetermined direction, and basically includes a motor disposed on the frame 21, a drive gear provided on the motor shaft, and a frame. 21 or a motor control circuit disposed at another position. When the driving gear is directly engaged with the outer teeth 22a3 of the rotor 22 using the communication hole 21c2 of the frame 21 or via the relay gear, the rotor 22 is moved in a predetermined direction by a motor operation. The rotation of the rotor 22 can be stopped by stopping the motor operation.

That is, in this feeder main body 20, the rotor 22 provided in the frame 21 can be rotated by a rotor drive mechanism, and the permanent magnet 22c arrange | positioned at the rotor 22 according to this rotation is rotated. It can be moved under the circular arc orbit corresponding to the virtual circle VC.

7 shows that the first support wall 21d and the second support wall 21e face each other in the front-rear direction as the frame 21, but the first support wall 21d and the second support wall are shown. Instead of (21e), a wall having a C-shaped upper surface shape (a wall in which the front and rear portions of the first and second support walls 21d and 21e are successively formed into walls having the same thickness as the front and rear portions) is formed. The front and rear gaps of the first support wall 21d and the second support wall 21e may be eliminated.

In addition, although FIG. 7 shows that the first leaf spring 21f and the second leaf spring 21g have a flat plate portion and an arc-shaped elastic portion continuous with the flat plate portion, bias in the same direction is shown. If it is a leaf spring in which a spring is formed, it may be used in place of a leaf spring of another shape, and a bias member other than the leaf spring, for example, a ball flanger (having a structure in which a part of the ball biased by the spring in the cylindrical body is exposed from the cylindrical body) ) May be used instead.

[Method of Attaching a Component Storage Case (First Embodiment) to a Feeder Body Suitable for the Component Storage Case]

Next, referring to FIG. 10 and FIG. 11, the "method of installing the component storage case (first embodiment) in the feeder main body suitable for the component storage case" will be described. In this description, for convenience of explanation, the left, right, front, inside, top, and bottom of FIG. 10 are referred to as front, back, left, right, top, and bottom, respectively, and the directions corresponding to these in FIG. 11 are referred to the same. . In addition, the + mark written in FIG. 10 shows the position corresponding to the center of rotation of the rotor 22, ie, the center of the circular arc orbit corresponding to the virtual circle VC.

When installing the component storage case 10 shown in FIG. 2 to the feeder main body 20 shown in FIG. 8, as shown in FIG. 10, the component storage case 10 is gripped by a finger | tip or the like. After positioning the bottom surface of the component storage case 10 to face the bottom surface (top surface of the bottom wall 21a) of the case mounting portion MS of the frame 21, the component storage case 10 Is inserted into the case mounting portion MS from above, and the bottom surface thereof is brought into contact with the top surface of the bottom wall 21.

In this process, as shown in FIG. 11, the component storage case 10 is biased to the right direction by each 1st leaf spring 21f, and the right surface of the said component storage case 10 is the rotor arrangement part 21c. ) Is pressed against the seat of the seat. At the same time, the component storage case 10 is biased in the front direction by the respective second leaf springs 21g, so that the front surface of the component storage case 10 is formed of the first support wall 21d. It is pressed against the rear of the left and right portions. Thereby, the three-dimensional position of the component storage case 10 provided in the case mounting part MS is determined.

When removing the component storage case 10 installed in the case mounting portion MS of the feeder main body 20 from the feeder main body 20, the upper protruding portion of the component storage case 10 is gripped with a fingertip or the like. The component storage case 10 may be pulled out upward by resisting the biasing force of each of the first leaf springs 21f and the second leaf springs 21g.

[Position relation between parts storage case and rotor in a state where parts storage case (first embodiment) is installed in feeder main body]

Next, with reference to FIG. 12 and FIG. 13, "the positional relationship of a component storage case and a rotor in the state which installed the component storage case (1st Embodiment) in the feeder main body" is demonstrated. In this description, for convenience of explanation, the left, right, front, inside, top, and bottom of FIG. 12 are referred to as front, back, left, right, top, and bottom, respectively, and the directions corresponding to these in FIG. 13 are called the same. . In addition, the + mark written in FIG. 12 shows the position corresponding to the center of rotation of the rotor 22, ie, the center of the circular arc orbit corresponding to the virtual circle VC.

In the state where the component storage case 10 shown in FIG. 2 is attached to the feeder main body 20 shown in FIG. 8, as shown to FIG. 13A-FIG. 13C, the rotor 22 ), The left surface (left surface of the ring-shaped opening 22a1) is parallel to the right surface of the component storage case 10 via the smallest gap (unsigned) allowing the rotation of the rotor 22. Facing closer to this state.

In addition, as shown in FIG. 12, the center of rotation of the rotor 22 is the outer circular arc surface of the circular arc sphere 12b constituting the guide port 15 and the supply passage 16 of the component storage case 10. 12b1) and the center of curvature of the inner arc surface 12b2, and the center of the virtual circle VC (= center of circular orbit) in which the center of one pole of each permanent magnet 22c are located.

The radius of curvature of the virtual circle VC (= radius of curvature of the circular orbit) is set to satisfy the condition of less than the radius of curvature of the outer arc surface 12b1 and more than the radius of curvature of the inner arc surface 12b2. As shown in FIG. 13, one magnetic pole of each permanent magnet 22c moving under an arc orbit corresponding to the virtual circle VC faces the guide port 15 and the supply passage 16. In addition, each center points in the guide 15 and in the supply passage 16.

In addition, since the right plate 12 of the component storage case 10 is capable of transmitting magnetic force, the magnetic force of the permanent magnet 22c facing the guide 15 may be transferred to the inside of the guide 15 through the right plate 12. The magnetic force of the permanent magnet 22c which extends in the storage chamber 14 and faces the supply passage 16 extends through the right plate 13 in the supply passage 16.

Here, referring to FIG. 13, in the case where the component PA1 shown in FIG. 1A is supplied, and the circular arc tool 12b shown in FIG. Regarding a specific example that satisfies the condition "the radius of curvature of the virtual circle VC (= the radius of curvature of the circular orbit) is less than or equal to the radius of curvature of the outer arc surface 12b1 and more than or equal to the radius of curvature of the inner arc surface 12b2". Explain.

FIG. 13A shows a specific example in the case of "curvature radius of virtual circle VC = [curvature radius of outer circular surface 12b1 + curvature radius of inner circular surface 12b2)] / 2", FIG. 13B shows "[curvature radius of outer circular surface 12b1 + curvature radius of inner circular surface 12b2] / 2> radius of curvature of virtual circle VC> radius of curvature of inner circular surface 12b2. 13 (C) shows the "curvature radius of the outer arc surface 12b1> curvature radius of the virtual circle VC> [curvature radius of the outer arc surface 12b1 + inner arc surface. A specific example in the case of [curve radius of (12b2)] / 2 "is shown.

Under the above conditions, the specific example shown in Fig. 13A is most preferable, and the specific example shown in Fig. 13B or 13C is preferable, but if the above conditions are satisfied, Even if the radius of curvature of the virtual circle VC = the radius of curvature of the outer arc surface 12b1 "or" the radius of curvature of the virtual circle VC = radius of curvature of the inner arc surface 12b2 ", It is sufficiently possible to carry out the acceptance of the parts under high probability.

I omitted the city,

When the component PA1 shown in FIG. 1A is supplied, and the circular arc sphere 12b shown in FIG. 4B is employ | adopted.

When the component PA2 shown in FIG. 1B is supplied, and the circular arc sphere 12b shown in FIG. 4C is employ | adopted.

When the component PA3 shown in FIG. 1C is supplied, and the circular arc sphere 12b shown in FIG. 4D is employ | adopted.

· A part having a shape similar to the shape shown in Figs. 1A to 1C, a spherical part, and the like are to be supplied, and the parts can be accommodated in a predetermined direction so as to be movable. Even when the circular arc tool 12b having a cross-sectional shape that can be used is the same, the same specific examples as described above can be appropriately employed.

[Part supply operation of the bulk feeder configured by installing a part storage case (first embodiment) to the feeder main body]

Next, with reference to FIGS. 14-19, the case where the part PA1 shown in FIG. 1A is made into a supply object and the circular arc sphere 12b shown in FIG. 4A is employ | adopted As an example, the "part supply operation of the bulk feeder comprised by attaching a component storage case (1st Embodiment) to a feeder main body" is demonstrated.

In this description, for convenience of explanation, the left, right, front, inside, top, and bottom of FIG. 14 are referred to as front, back, left, right, top, and bottom, respectively, and the directions corresponding to these in the other drawings are called the same. . 14 and 19 indicate the position corresponding to the center of rotation of the rotor 22, that is, the center of the circular arc orbit corresponding to the virtual circle VC.

At the time of component supply, the component storage case in which the plurality of components PA1 are stored in a single state (a state in which the direction is not constant) is stored in the storage chamber 14 of the component storage case 10 shown in FIG. 2. Prepare (10). And this component storage case 10 is attached to the feeder main body 20 shown in FIG. 8 by the method mentioned above (refer FIG. 10 and FIG. 11).

The storage of the parts PA1 into the storage chamber 14 of the component storage case 10 can be closed with a refill port (not shown) with an opening / closing cover provided in the component storage case 10 or a seal. It is carried out through supplementary equipment (not shown). If the storage amount of the component PA1 is too large, the probability of inflow of the component PA1 into the inlet 16a to be described later decreases, so that the maximum storage level of the component PA1 is about 1 / of the height of the storage chamber 14. It is preferable to set it as 2. For example, when the length L1 of the component PA1 is 1.0 mm, the component storage case 10 having the same dimensions as the actual dimensions shown in Figs. 2A to 2C is created. Even when the maximum storage level is about 1/2 of the height dimension of the storage chamber 14, tens of thousands of parts PA1 can be stored.

Subsequently, the feeder main body 20 in which the component storage case 10 is installed, that is, a bulk feeder (unsigned), is mounted on the feeder mounting table of the mounter (part mounting apparatus). As shown in Fig. 14, the rotor 22 is rotated by a predetermined angle, for example, 180 to 1,080 ° in the direction toward the outlet 17, so as to preliminarily supply the part PA1 (so-called ball filling) ).

As the rotor 22 rotates, the permanent magnets 22c provided to the rotor 22 are

Process PR1: The process in which one magnetic pole of the permanent magnet 22c faces the storage compartment 14 and moves while facing the guide 15.

Process PR2: The process in which one pole of the permanent magnet 22c moves in a state not facing the storage chamber 14 and facing the supply passage 16.

Process PR3: The one-pole magnetic pole of permanent magnet 22c does not oppose the storage chamber 14, and moves so that the process which moves in the state which does not face supply passage 16 may pass in order.

In the process PR1, the plurality of parts PA1 of the parts PA1 in the individual state accommodated in the storage chamber 14 are attracted in the direction of the guide opening 15 by the magnetic force of the permanent magnet 22c, The plurality of sucked parts PA1 exit from the parts storage area in the form of lumps and move upward along the guide 15 to reach the blowing holes 16a.

Specifically, two flat surfaces FP1 and FP2 exist in the state of being in a plane while the guides 15 are interposed between the outer side and the inner side of the guide 15, and one magnetic pole of the permanent magnet 22c. Since the center of is directed into the guide 15, the lump of the plurality of parts PA1 sucked in the direction of the guide 15 by the magnetic force of the permanent magnet 22c, as shown in FIG. It forms in the form of a mountainous tongue (refer to the dashed-dotted line) which covers the guide tool 15 and the flat surfaces FP1 and FP2 on both sides, or the shape close | similar to this. That is, using the flat surfaces FP1 and FP2 existing on the outer side and the inner side of the guide 15, as many parts PA1 as possible are attracted to the guide 15 direction.

The number of the parts PA1 sucked in the direction of the guide opening 15 by the magnetic force of the permanent magnet 22c is determined by the remaining number of parts PA1 in the storage chamber 14, the surface magnetic force of the permanent magnet 22c, and the like. Although it depends, a sufficient amount of parts PA1 is accommodated in the storage chamber 14, and the permanent magnet 22c has a surface magnetic force of, for example, 2,000 to 4,000 gauss, so that sufficient magnetic force is applied to the components in the storage chamber 14 ( In the case of reaching PA1), there are approximately tens to hundreds.

In addition, since the center of one magnetic pole of the permanent magnet 22c is directed into the guide tool 15, the center of the plurality of parts PA1 is closest to the permanent magnet 22c and at the center (magnetic center). The force drawn in the guide 15 is most strongly acted on the facing part PA1. When the mass of the plurality of parts PA1 moves upward along the guide 15, the component PA1 close to the guide 15 in the mass of the plurality of parts PA1 is the guide 15. The two circular arc-shaped edges on the opening side of the c) come into contact with each other to correct the direction thereof.

That is, in the above-described process PR1, the guide tool 15 is driven by the magnetic force of the permanent magnet 22c due to the attraction of as many parts PA1 as possible in the direction of the guide opening 15 by the magnetic force of the permanent magnet 22c. One or a plurality of parts PA1 of the plurality of parts PA1 sucked in the) direction can be accommodated in the guide 15 in the longitudinal direction with a high probability based on the above-described action.

In addition, in order to form the rectangular parallelepiped shape which has the dimension relationship of length L1> width W1 = height H1, the part PA1 has the direction of the part PA1 accommodated in the guide tool 15 basically. Denotes two patterns in the longitudinal direction (see FIG. 16) and in a direction different from the longitudinal direction by 90 ° (see FIG. 17), and the parts PA1 not accommodated in the guide 15 are in a single state (FIG. 15).

When one or more parts PA1 accommodated in the guide 15 are all "parts PA1 accommodated in the longitudinal direction in the guide 15," or "parts accommodated in the longitudinal direction in the guide 15. When the part PA1 accommodated in the direction different from the longitudinal direction by 90 degrees in the guide tool 15 exists in the back side of PA1, as shown in FIG. 16, it is shown in the longitudinal direction in the guide tool 15. As shown in FIG. The accommodated part PA1 "moves upward along the guide port 15 while being attracted by the magnetic force of the permanent magnet 22c, flows into the inlet port 16a in the same direction, and enters the supply passage 16. As shown in FIG. Blown. At the time of inflow, the parts PA1 accommodated in the direction different from the longitudinal direction in the guide tool 15 and the parts PA1 not accommodated in the guide tool 15 are left of the inlet 16a. A second magnetic pole of the permanent magnet 22c passes through the right side of the intake opening 16a, and falls downward where the suction force is lowered.

In view of the above effect, it is unlikely that one or more parts PA1 housed in the guide tool 15 are all "parts PA1 housed in the direction different from the longitudinal direction in the guide tool 15 by 90 °". In this case, as shown in FIG. 17, the "part PA1 accommodated in the direction different from the longitudinal direction in the guide tool 15 by 90 degrees" and the "part PA1 not accommodated in the guide tool 15" are shown in FIG. Abuts against the second plane 11b4 existing on the left side of the intake port 16a, and one magnetic pole of the permanent magnet 22c passes through the right side of the intake port 16a and falls downward from the place where the suction force is lowered. .

Moreover, in the said process PR2, the longitudinal part PA1 which flowed in from the guide port 15 to the blow inlet 16a is attracted by the magnetic force of the permanent magnet 22c, as shown in FIG. While moving upward along the supply passage 16 to reach the outlet 19, the front surface of the stopper 13 stops at a position abutting on the rear end. At the time of preliminary supply, since the rotor 22 rotates, for example, 180 to 1,080 °, the state in which the plurality of parts PA1 are arranged on the rear side of the first part PA1 which comes into contact with the rear end of the stopper 13 and stops. do.

In the process PR3, since the magnetic force of the permanent magnet 22c does not reach the part PA1 in the storage chamber 14, the storage chamber 14 is controlled by the magnetic force of the permanent magnet 22c. Unnecessary fluctuations in the parts PA1 in the inside, for example, fluctuations that do not contribute to part receipt into the guide port 15 or inflow of parts into the inlet port 16a, are prevented from occurring.

After the preliminary supply is completed, as shown in FIG. 19 and FIG. 20, one magnetic pole of the permanent magnet 22c exists at a position passing through the right side of the outlet 17, and furthermore, in the permanent magnet 22c. The rotor 22 is stopped so that one magnetic pole of the subsequent permanent magnet 22c on the right side of the supply passage 16 stops (hereinafter, the stop position of the rotor 22 is referred to as the rotor stop position). ).

Extraction of the leading part PA1 by the suction nozzle (not shown) of the mounter is performed at this rotor stop position. Specifically, the adsorption nozzle is lowered toward the outlet 17 to adsorb the leading component PA1, and then the adsorption nozzle is raised, and the component PA1 taken out through the outlet 17 is a circuit. It is mounted on mounted objects, such as a board | substrate. Since the outlet 17 is located at the highest point of the arc-shaped supply passage 16, a plurality of parts PA1 are arranged in the rear side of the head part PA1 which contacted the rear end of the stopper 13 and stopped. Even if it is, the load which causes trouble in taking out from the subsequent part PA1 to the head part PA1, for example, a pressing force, etc., is not applied.

The intention of setting the rotor stop position as described above is

Intent IN1: When the leading part PA1 is taken out through the blowout port 17 by the adsorption nozzle of a mounter, the attitude | position of the taken out part PA1 by the influence of the magnetic force of the permanent magnet 22c, Avoiding disorientation of suction position

Intention IN2: Even if other parts PA1 except for the first part PA1 among the parts PA1 existing in the supply passage 16 self-move downwardly along the supply passage 16, the above-mentioned. By restraining the weight transfer by suction according to the magnetic force of the rear permanent magnet 22c, the other parts PA1 are prevented from being discharged from the supply passage 16 and returning to the storage chamber 14. .

After the leading part PA1 is taken out by the suction nozzle of the mounter through the blower outlet 17, the rotor 22 at the rotor stop position is set at a predetermined angle, for example, 45 ° or 90 ° in the direction toward the blower outlet 17. The rotor 22 is again stopped at the rotor stop position by rotating the angle or 135 degrees or 180 degrees. The extraction of the component PA1 by the suction nozzle can be easily detected by a sensor (not shown), so that the rotation of the rotor 22 can be started based on the detection signal.

When the rotor 22 at the rotor stop position is rotated a predetermined angle in the direction toward the ejection opening 17, the "acceptance of the parts PA1 into the guidance opening 15" and "the entrance opening 15 from the guidance opening 15" Inflow of component PA1 into 16a "and" movement of component PA1 in supply passage 16 "are performed in the same manner as described above, and component PA1 is again supplied to outlet 17. After this, whenever the leading part PA1 is taken out through the ejection opening 17, the rotor 22 in the rotor stop position rotates a predetermined angle in the direction toward the ejection opening 17. FIG.

In addition, the above-mentioned "part feed operation of a bulk feeder" is made to supply the parts PA1 shown in FIG. 1A, and employs the circular arc tool 12b shown in FIG. 5A. Although the case has been explained by way of example,

When the component PA1 shown in FIG. 1A is supplied, and the circular arc sphere 12b shown in FIG. 5B is employ | adopted.

When the component PA2 shown in FIG. 1B is supplied, and the circular arc sphere 12b shown in FIG. 5C is employ | adopted.

When the component PA3 shown in FIG. 1C is supplied, and the circular arc sphere 12b shown in FIG. 5D is employ | adopted.

· A cross section capable of supplying a component similar to the shape shown in FIGS. 1A to 1C, a component forming a sphere, and the like so as to be movable in a predetermined direction. Even in the case of employing the circular arc tool 12b having a shape, the same "part feed operation of the bulk feeder" as described above can be realized regardless of the size of the parts. In these cases, when "the component PA1 shown in FIG. 1A is a supply object and the circular arc tool 12b shown in FIG. 5B is employ | adopted," FIG. As indicated by the broken line in B), the component PA1 can be accommodated in the guide 15 in the longitudinal direction in which the planes of the width or height do not coincide, but the process of moving in the guide 15 or the supply passageway. In the process of moving in (16), since the displacement which stabilizes a posture arises in the part PA1 itself, the said part PA1 is supplied to the ejection opening 17 in the attitude | position of the width | variety or height.

12, the radius of curvature of the virtual circle (not shown) which surrounds the outer side of eight permanent magnets 22c in total is almost the radius of curvature of the 1st circular arc surface 12b1 which comprises the storage chamber 14. In FIG. Although the coincidence is shown, when the width of the outer flat surface FP1 is enlarged or when the permanent magnet 22c having a small diameter is used, the imaginary circle is positioned inside the first arc surface 12b1, Using a large permanent magnet 22c having a diameter, the imaginary circle is located outside the first arc surface 12b1.

[Part replacement work and Part change work]

Next, on the premise that a plurality of bulk feeders (indicating that the component storage case 10 is installed in the feeder main body 20) that can supply different kinds of parts to the feeder mounting table of the mounter are provided side by side, About,

Replenishment of parts (replenishment of parts in the bulk feeder's compartment with fewer parts)

· Describe the part change operation (change of parts that can be supplied from each bulk feeder to another type of part).

During these operations, a number of parts storage cases 10 containing parts, such as those supplied from a plurality of bulk feeders installed on the feeder mount of the mounter, are prepared, and a plurality of bulk feeders installed on the mounter feeder mounts are provided. The necessary number of parts storage case 10 containing the parts to be supplied and other parts is prepared and stored in the vicinity of the mounter.

The mounter needs to replenish the parts to a specific bulk feeder with a small number of parts remaining by repeating the operation of selectively taking out parts to be mounted on the mounted object from a plurality of bulk feeders. In this case, the component storage case 10 is separated from the feeder main body 20 of a specific bulk feeder, and the component storage case 10 in which the same kind of parts are accommodated is installed in the feeder main body 20. The attachment / detachment method of the component storage case 10 at this time is as described above with reference to FIGS. 10 and 11.

On the other hand, since the parts to be mounted change according to the change of the mounted object, it is necessary to change the parts supplied by the specific bulk feeder capable of supplying the non-mounted parts to other kinds of parts (points having different sizes or shapes). Occurs. In this case, the component storage case 10 is separated from the feeder main body 20 of a specific bulk feeder, and the component storage case 10 in which other types of components are stored is provided in the feeder main body 20. The attachment / detachment method of the component storage case 10 at this time is as described above with reference to FIGS. 10 and 11.

The reason that these "part replacement work" and "part change work" can be performed by the replacement work only for the parts storage case 10 is,

The bulk feeder is constituted from the feeder main body 20 and the component storage case 10 detachable from the feeder main body 20.

The ratio which changes according to the size and shape of a component among the essential elements after realizing the original function of a bulk feeder (the function which supplies the components accommodated in the state in the storage chamber 14 to the ejection opening 17 in a predetermined direction). Common elements (guides 15, supply passages 16 and outlets 17) are provided in the part storage case 10, and are common elements that are not changed by the size and shape of the parts (movable under a predetermined arc orbit). Permanent magnet 22c] is provided in the feeder main body 20.

[Effects Based on Component Storage Case (First Embodiment)]

The component storage case 10 includes a non-common element that varies with the size and shape of the component, and the component storage case 10 has a feeder body having a common element that does not change with the size and shape of the component. Since the parts 20 can be attached and detached, even when the parts storage case 10 installed in the feeder main body 20 is replaced with another parts storage case 10, the same parts supply operation as before the replacement can be performed regardless of the type of parts. It can be realized. That is, the parts storage case 10 can perform the desired "parts replenishment work" and "parts change work" correctly by simple replacement work, and can exhibit the original function of a bulk feeder after a replacement without interruption.

In short, the component storage case 10, in addition to performing the role of a package in which components are stored, requires little storage space and does not require special maintenance during storage. Part disadvantages, ie

Taking time to replenish parts

· Spilling out parts during replenishment work

· Storage of multiple bulk feeders for changing parts in advance in order to carry out the parts changing work (requires corresponding storage space)

• It is possible to reliably solve the necessity of maintenance of the part change bulk feeder stored in order to perform the part change operation, and to reduce the overall cost.

In addition, since the replacement parts storage case 10 can be reused, when the parts storage case 10 after replacement is recovered and the parts are replenished, the replacement parts storage case 10 is used as the replacement parts storage case 10. Resource saving by reusing can be aimed at.

In addition, since attachment and detachment of the component storage case 10 with respect to the feeder main body 20 can be performed by installation by fitting from the upper part of the said component storage case 10, and removal by extraction to the upper direction, Even when adjacent spaces of a plurality of bulk feeders provided in the feeder mount of the mounter are narrow, the desired "part replenishment work" and "part change operation" can be performed without removing the bulk feeder from the feeder mount.

[Structure of Parts Storage Case (2nd Embodiment)]

Next, with reference to FIG. 21, the "structure of a part storage case (2nd Embodiment)" is demonstrated. In this description, for convenience of explanation, the left, right, bottom, top, front, and inside of FIG. 21 are referred to as front, back, left, right, top, and bottom, respectively.

The part storage case 10-1 shown in FIG. 21 is different from the part storage case 10,

The stopper 13 has a magnetizable stopper 13-1.

The stopper 13-1 is magnetizable by the magnetic force of the permanent magnet 22c of the rotor 22. Specifically, the stopper 13-1 is formed of a bar or ferromagnetic material formed from a material such as iron or nickel belonging to the ferromagnetic material. A layer formed of a bar formed by plating or the like of a separate material belonging to a ferromagnetic material as a whole on the surface of the base material made of a material belonging to a layer formed of a material belonging to a ferromagnetic material Rods formed by plating or the like are used.

If the stopper 13-1 is capable of being magnetized by the magnetic force of the permanent magnet 22c, the stopper 13-1 is magnetized by the magnetic force of the permanent magnet 22c on the front side that has passed through the right side of the outlet 17. In this way, the first component PA1 in contact with the rear end of the stopper 13-1 can be attracted to the rear end by the magnetic force generated at the rear end of the stopper 13-1.

In the component storage case 10-1, the magnetic force based on one magnetic pole of the permanent magnet 22c on the front side reaches the front end of the stopper 13-1 at the rotor stop position, and the stopper 13-1 magnetizes. When the magnetized stopper 13-1 has the same polarity as the one-pole magnetic pole, the magnetic component based on the polarity attracts the leading part PA1 abutted at the rear end of the stopper 13-1. The leading part PA1 is retained by adsorption. The magnetic force generated at the rear end of the stopper 13-1 is a magnetic force having a slight degree of being able to hold the leading part PA1 abutted at the rear end of the stopper 13-1 in a contact state, for example, several gauss to several tens. If it is about Gaussian, the said holding | maintenance can fully be performed.

When the stopper 13-1 is magnetized by the magnetic force of the front permanent magnet 22c, the adjustment of the magnetic force (adjustment of the adsorption force) generated at the rear end of the stopper 13-1 is to change the rotor stop position, That is, it can implement simply by changing the angle (theta) shown in FIG. For example, in the rotor stop position shown in FIG. 20, when the adsorption force is too strong, the angle? May be increased so that the permanent magnet 22c on the front side may be released from the stopper 13-1. In the rotor stop position, when the suction force is too weak, the angle? May be reduced so that the permanent magnet 22c on the front side approaches the stopper 13-1.

The action is,

When the component PA1 shown in FIG. 1A is supplied, and the circular arc sphere 12b shown in FIG. 5B is employ | adopted.

When the component PA2 shown in FIG. 1B is supplied, and the circular arc sphere 12b shown in FIG. 5C is employ | adopted.

Even when the circular arc tool 12b which has a shape is employ | adopted, it can exhibit similarly irrespective of the magnitude | size of a component.

[Effects Based on Component Storage Case (Second Embodiment)]

According to the said component storage case 10-1, by the magnetic force of the stopper 13-1 magnetized in the rotor stop position, the head part which contact | connected the rear end of the said stopper 13-1 is attracted, and The position and attitude of the first part can be held. That is, by stabilizing the position and attitude of the leading part abutting on the rear end of the stopper 13-1, the leading part can be taken out better by the adsorption nozzle of the mounter, and the leading part Even if this time interval for taking out is shortened, for example, even when the time interval for taking out parts is 50 msec or less, the taking out of parts can be performed accurately.

In addition, if a permanent magnet stopper of the same size as the stopper 13-1 is used in place of the magnetizable stopper 13-1, holding of the leading part by magnetic force can be achieved. Using the component increases the component cost compared to the case where the stopper 13-1 is used. In addition, since the permanent magnet stopper has a unique surface magnetic force, the above-described adjustment of the attraction force cannot be performed. That is, in order to solve such a disadvantage, the system which magnetizes the stopper 13-1 by the magnetic force of the permanent magnet 22c which passed through the right side of the blowout port 17 is employ | adopted.

Since the other effect obtained based on the said component storage case 10-1 is the same as the effect described in the "effect based on a component storage case (1st Embodiment)", the description is abbreviate | omitted.

The height of the lower surface of the shutter arrangement recess 11c substantially coincides with the height of the upper surface of the ejection opening 17, and on the left side of the shutter arrangement recess 11c, the upper surface of the fixing portion 18a of the shutter 18 is shown. The holding part 11c1 which conformed to the outline is provided. Moreover, the to-be-pressed part 12e which the to-be-pressed part 18e of the shutter 18 enters in the front side rather than the recessed part 12d of the upper surface of the upper surface 12-1 of the component storage case 10-2. Is installed. The height of the lower surface of the recessed portion 12e for the press portion is substantially equal to the height of the lower surface of the recessed portion 11c for shutter placement and the height of the upper surface of the ejection port 17.

As can be seen from Fig. 22, the fixing portion 18a, the elastic portion 18b and the arm portion 18c of the shutter 18 are accommodated in the shutter arrangement recess 11c, and the fixing portion 18a is held by the holding portion ( 11c1) is provided by infiltrating using an adhesive agent as needed. Moreover, the opening-closing part 18d enters the blower outlet 17, and covers the one part or all part of the blower outlet 17. As shown in FIG. Moreover, the to-be-pressed part 18e is located in the recessed part 12e for a to-be-pressed part, and the front-end | tip protrudes to the right from the right side of the component storage case 10-2.

On the other hand, a total of eight pressing portions 22a4 are formed in the rotor 22-1 so as to cut off portions where the permanent magnets 22c of the ring-shaped extension portions 22a1 are not arranged. Each press part 22a4 has the mountain shape which has the inclined surface front and back, and the arc-shaped recessed part 22a5 which exists between the left-right dimension (height) of each press part 22a3, ie, between the adjacent press parts 22a4. The depth of S is slightly larger than the tip protruding dimension of the to-be-pressed part 18e of the shutter 18.

In this component storage case 10-2, as shown in FIG. 23, the to-be-pressed part 18e of the shutter 18 by the press part 22a4 of the rotor 22-1 in the rotor stop position. Is pressed to the left, the arm portion 18c, the opening and closing portion 18d and the pressurized portion 18e are displaced to the left side based on the deformation of the elastic portion 18b, and the opening and closing portion 18d is ejected from the outlet 17 by the displacement. ), The outlet 17 is opened. In addition, as shown in FIG. 22, when the rotor 22-1 rotates and the pressurization of the to-be-pressed part 18e of the shutter 18 is released, the arm part 18c is based on the elasticity of the elastic part 18b.

The leading part can be taken out. That is, when the rotor 22-1 is not in the rotor stop position, part or all of the ejection opening 17 can be covered by the opening and closing portion 18d of the shutter 18, so that the permanent magnet 22c is ejected from the ejection opening 17. When passing through the right side, the opening / closing part 18d reliably prevents the posture of the leading part which abuts and stops at the rear end of the stopper 13 under the influence of the magnetic force of the permanent magnet 22c. Even if the time interval at which the leading part is taken out is shortened, for example, even when the time interval for taking out parts is 50 msec or less, the parts can be taken out accurately.

As shown in FIG. A hole of a predetermined depth formed in the seat surface is provided by penetrating with an adhesive as necessary.

Moreover, the some permanent magnet 25a which exists in the part wound by the 1st pulley 23 of the endless belt 25 is centered on the center of one magnetic pole of each permanent magnet 25a (the center of magnetic force in which a magnetic field line is densest concentrated). Equivalent) is located on the virtual circle VC concentric with the rotation center of the 1st pulley 23 (same diameter as the virtual circle VC of the rotor 22). The radius of curvature of the virtual circle VC (= radius of curvature of the circular orbit) is the outer circle of the circular arc sphere 12b constituting the guide port 15 and the supply passage 16 of the component storage case 10-3. It is set so as to satisfy the condition of the curvature radius of the arc surface 12b1, and more than the curvature radius of the inner side arc surface 12b2.

Moreover, the thing which has sufficient surface magnetic force is used for each permanent magnet 25a also in order to attract the component in the storage chamber 14 to the guide opening 15 direction. The polarity of one pole of each permanent magnet 25a may be either the N pole or the S pole, or the N pole and the S pole may be arranged alternately depending on the virtual circle VC.

The rotor drive mechanism (not shown) is for rotating and stopping the endless belt 25 in a predetermined direction and basically includes a motor disposed on the frame 21-2 and a drive gear provided on the motor shaft. And a motor control circuit arranged at the frame 21-2 or at a separate position. If the driven gear is provided to one of the 1st pulley 23 and the 2nd pulley 24, and a drive gear is directly engaged with the driven gear via a relay gear, it will be stepless by a motor operation. The belt 25 can be rotated in a predetermined direction, and the rotation of the endless belt 25 can be stopped by stopping the motor operation.

That is, in this feeder main body 20-2, the endless belt 5 provided in the frame 21-2 can be rotated by the rotor drive mechanism, and it arrange | positioned at the said endless belt 25 according to this rotation. The permanent magnet 25c can be moved under the arc orbit corresponding to the virtual circle VC.

The detachment method of the component storage case 10-3 with respect to the feeder main body 20-2 is the same as the detachment method demonstrated above with reference to FIG. In addition, "the positional relationship of a component storage case and a rotor" in the state which installed the component storage case 10-3 in the feeder main body 20-2 is the positional relationship demonstrated previously with reference to FIG. 12 and FIG. Is the same as In addition, the "part feed operation of a bulk feeder" formed by installing the part storage case 10-3 on the feeder main body 20-2 is also the same as the part feed operation described above with reference to FIGS. 14 to 19.

In addition, although the feeder main body 20-2 differs in part from the structure of the feeder main body 20-1 shown in FIG. 25, the feeder main body 20-2 is used instead of the feeder main body 20-1. Even if it is a case, the effect obtained based on the said component storage case 10-3 is the same as the effect described in the said "effect based on a component storage case (4th Embodiment)".

In addition, although the permanent belt 25 of the feeder main body 20-2 was shown to arrange a total of ten permanent magnets 25a at equal intervals, the same as the case of the rotor 22, the permanent magnet ( The number and interval of 25a) may be increased or decreased. In addition, although the space | interval of the permanent magnet 25a may not be equal intervals, it is easy to control the rotation of the endless belt 25 in the component supply operation | movement in the equal interval.

In addition, the configuration of the case mounting portion MS of the feeder main body 20-2 is changed to the configuration of the case mounting portion MS of the feeder main body 20, and instead of the component storage case 10-3. The component storage cases 10, 10-1, and 10-2 may be used for the attachment and detachment of the component storage case 10 with respect to the feeder main body in this case. Same as the method.
