[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply apparatus which inserts a plurality of components, in particular, components for assembling electronic equipment, into a stick-shaped cartridge, and removes and supplies them one by one.

[0002]

2. Description of the Related Art Conventionally, a component supply apparatus 1 as shown in FIG. 14 has been used for an assembly line of electronic equipment.
In the frame 2 of the component supply device 1, guides 2a and 2b extending vertically upward are erected on a horizontal base 2c at intervals. Chuck cylinders 3a and 3b are mounted on the upper portions of the guides 2a and 2b, respectively. Chucks 4a and 4b are attached to the lower ends of the chuck cylinders 3a and 3b, respectively. Base 2c on one guide 2a side
The component feed motor 5 is attached to the lower side. A component feed mechanism 6 is provided above the component feed motor 5.
On the other side of the base 2c, a take-out chute 7 and an escape elevating cylinder 8 are provided. An escape 9 is attached to the upper part of the escape lift cylinder 8 and an arrow 8
It moves up and down as shown in FIG.

[0003] A plurality of cartridges 10 are sandwiched between two guides 2a and 2b. Lowermost cartridge 11
Is located at the component supply position, and a clearance is provided between the cartridges 11 and 12 thereon. Chuck 4a, 4
In the case b, both ends of the second stage cartridge 12 are chucked and lifted. The clearance between the first-stage cartridge 11 and the second-stage cartridge 12 is such that the components inserted into the cartridge 11 are surely pushed out one by one by the component feed mechanism 6 and the empty cartridge is emptied. This is for making removal of 11 easy.

FIG. 15 shows a part 16 in a cartridge 10.
Shows the state of inserting a. The cartridge 10 is in the shape of a long stick whose cross section is almost rectangular. The component 16 is, for example, a transformer or a ceramic filter in a shield case. Component 1 inserted into cartridge 10
In a state where 6a and 16b are filled in a predetermined number, plugs are plugged on both sides to move between processes. Parts supply device 1
When installed on the inside, the plugs on both sides are removed and the internal components 16
a and 16b are extruded one by one and used. The cartridge 10 is manufactured by extrusion molding using a translucent plastic material.

FIG. 16 shows the operation of the chuck cylinder 3 and the chuck 4 shown in FIG. In FIG. 16 (1),
The chuck 4 chucks and holds the cartridge 10 in the direction of arrow 17. In FIG. 16 (2), the cartridge 10
Then, the chuck 4 is raised as shown by the arrow 18 in a state in which the chuck is held.

[0006]

In the conventional component supply device 1 as shown in FIG. 14, the second stage cartridge 12 is mounted so that the lowermost cartridge 11 at the component supply position is not burdened. I try to chuck. The chucks 4a and 4b chuck both sides of the cartridge 12 by separate chuck cylinders 3a and 3b. When the first cartridge 11 becomes empty, the cartridges 11 are removed and the chucks 4a, 4a are moved so that the second cartridge 12 comes from the supply position.
b needs to be released. This chuck release operation,
It is difficult for the two chucks 4a and 4b to perform completely simultaneously, and it is inevitable that a slight time difference occurs. For this reason, the cartridge which is released from the chucks 4a and 4b and falls may fall with a slant with respect to the guides 2a and 2b, and may be caught on the way or take time to move to the supply position. Also, if the cartridge is tilted, the inserted components may protrude.

Further, when the parts are heavy with a transformer including an iron core or the like, the cartridges 11 to 15 are bent as shown in FIG. 17, and the cartridges 11 to 15 which can be stacked between the guides 2a and 2b are used. The guide 2 is used to remove the limited or empty cartridge 11.
There is also a risk of being scratched at a and 2b. Also, the connection between the cartridge 11 at the component supply position and the take-out chute 7 is deteriorated, so that components cannot be delivered smoothly.

[0008] An object of the present invention is to provide a component supply device capable of smoothly and reliably sending out components.

[0009]

According to the present invention, there is provided a storage portion for holding a plurality of stick cartridges in which a plurality of parts are inserted in a horizontally stacked state, a moving portion for guiding the cartridge laterally from a lower end of the storage portion, Loading means having a dropping part for dropping the cartridge from the end of the moving part so as to guide the cartridge to a lower supply position, and moving means for moving the lowermost cartridge of the storage part of the loading means to the end of the moving part,
Provided on one end side of the cartridge guided to the supply position,

Further, the present invention provides an extruding means provided to face one end of a stick cartridge into which a plurality of parts are inserted, and extruding and supplying parts in the cartridge one by one to the other end of the cartridge. And a take-out means for moving the cartridge up and down while restricting the movement of the cartridge on a side surface in contact with the other end of the cartridge, and for taking out the part extruded by the extruding means. . Further, the present invention provides a loading device comprising two storage portions for holding a plurality of horizontally stacked stick cartridges into which a plurality of components are inserted, and a moving portion for guiding the cartridge laterally from a lower end of each storage portion. Means, a moving means for laterally moving one of the lowermost cartridges of the two storage portions of the loading means, and one part provided in one end of the cartridge moved by the moving means, and one part in the cartridge is provided. And a pushing means for pushing and supplying the other end of the cartridge to the other end side.

[0011]

According to the present invention, a plurality of stick-shaped cartridges are held in a horizontally stacked state. Since the weight of each cartridge is equally supported, there is no deflection due to the weight of the parts. The lowermost cartridge moves in the lateral direction, and the components in the cartridge are extruded one by one to the other end of the cartridge one by one by extruding means provided at one end thereof. The part pushed out to the other end of the cartridge is taken out by the take-out means. At the lowermost position, the upper cartridge falls smoothly according to the so-called darling principle. Since the components are pushed out at a position different from the position where the cartridges are stacked, interference with the cartridges in the stacked state is small, and the parts can be reliably supplied.

Further, according to the present invention, parts to be extruded one by one from one end of the cartridge are provided facing the other end of the cartridge. However, it can be reliably taken out by the take-out means that moves up and down. Since a take-out chute or the like is not provided between the other end of the cartridge and the take-out means, it is possible to avoid a situation in which parts are clogged in the middle of the take-out chute or the like and supply is stopped.

Further, according to the present invention, since two storage portions of the loading means are provided, the number of cartridges mounted at one time can be doubled.

The operation of the control device 60 starts from step a1 shown in FIG. In step a2, it is confirmed by the signal from the start position detection switch 51 that the push block 46 shown in FIG. When it is not at the start position, the component feed motor 35 is driven to move to the start position. In the next step a3, the receiving piece projecting cylinder 34 is driven to make the receiving piece 32 project. In the next step a4, the cartridge moving cylinder 26 is driven to move the lowermost cartridge to the supply position.

In the next step a5, the component feed motor 3
5 is driven to push out only one component in the cartridge 20. When the component detection sensor 59 detects a component, it is determined that only one component has been pushed out, and the driving of the component feed motor 35 is stopped. In the next step a6, the escape lift cylinder 38 is driven to raise the parts extruded by the escape 39. In the next step a7, the raised parts are reliably moved by an assembling robot or the like. In the next step a8, it is determined whether or not the cartridge is empty. For this determination, the signal from the end position detection switch 53 is used. When the signal is not detected from the end position detection switch 53, the cartridge is not empty and the parts are left.
Return to

In step a8, the end position detection switch 5
When a signal is generated from 3 and it is determined that the cartridge is empty, the process proceeds to step a9. In step a9, the receiving piece projecting cylinder 34 is driven to retract the receiving piece 32. This causes the cartridge that has been moved to the supply position to drop. Next, in step a10, the operation for one cartridge is completed. By repeatedly performing the operations from step a1 to step a10, it is possible to continuously supply components from the stacked cartridges.

FIG. 9 shows another embodiment of the present invention. It should be noted that the supply chute 61 has two guides 61a, 6
1b, and a cartridge moving cylinder 6
2a and 62b are provided respectively. The cartridges 20 stacked in the guides 61a and 61b are moved by the cartridge moving cylinders 62a and 62b.
Moves to the supply position 64 on the intermediate bottom plate 63. Thus, since the guides 61a and 61b of the supply chute 61 are provided on both sides of the supply position 64, the number of cartridges 20 to be mounted at one time is doubled.

FIG. 10 shows still another embodiment of the present invention. In the present embodiment, the cartridge 70 is
Guided by 1, 72, 73, an escape 74 is provided facing the side where the parts of the cartridge 70 are extruded. The escape 74 is provided with through holes 74a and 74b, and detects a component when the component 56 blocks light from the light emitting element 75 and the light receiving element 76. The detection of the component 56 is also performed by the light emitting element 77 and the light receiving element 78.

FIG. 11 shows a sectional structure of the cartridge 70. On the cartridge 70, a projection 70a is formed on the inner side to support the component 56 such as an intermediate frequency transformer without imposing a load on the lead terminal. FIG. 12 shows the operation of the component supply device of the present embodiment. FIG. 12A shows a state in which the plugs sealing both ends of the cartridge 70 are removed with the components 56a and 56b inserted into the cartridge 70. The surface 74c of the escape 74 facing the cartridge 70 regulates the movement of the cartridge 70. The parts 56a and 56b are pushed toward the escape 74 by a rod 80 driven by a cylinder 79. When the extrusion is started, first, as shown in FIG. 12 (2), the clearance between the components 56a and 56b disappears. FIG. 12 (3)
As shown in (1), when one component 56a moves on the escape 74, the pushing by the cylinder 79 stops. In FIG. 12 (4), the escape 74 is raised by the escape lifting cylinder 38. Elevated component 56a
Is taken out by an assembling robot or the like as indicated by an arrow 82. Hereinafter, the operations from FIG. 12 (2) to FIG. 12 (4) are repeated, and parts are supplied one by one.

It should be noted in this embodiment that the take-out chute 37 as shown in FIG. 3 is not used. The take-out chute 37 requires fine adjustment of the interval between the back plates 83 as shown in FIG. If the distance is too small, the components 56a and 56b cannot be moved smoothly. If the interval is too wide, the components 56a and 56b are inclined and are likely to be clogged. In addition, since a certain number of parts stay in the supply chute 37, when the different parts 84 are mixed by mistake, it takes time to repair the different parts 84 before they are extruded. According to the present embodiment, since there is no need to provide the take-out chute 37, it is easy to take out the parts reliably.

If a conductive cartridge is used,
Of course, it is possible to prevent electrostatic breakdown of semiconductor components and the like.

[0028]

As described above, according to the present invention, since a plurality of cartridges in which a plurality of components are inserted are held in a stacked state, the cartridges are unlikely to bend even if the weight of the components is large. Since the stacked cartridges are dropped by a so-called darting method, the cartridges are reliably dropped. An average load is applied to the lowermost cartridge of the stacked cartridges, so that no bending or the like occurs. In addition, since concentrated loads are not applied to both ends and the like, the number of stacked cartridges can be increased. Since the cartridge does not bend, parts can be reliably supplied.

Further, according to the present invention, the parts pushed out from the other end by the pushing means provided at one end of the cartridge are immediately taken out by the taking out means. Also, parts can be reliably removed. According to the present invention,
The number of cartridges that can be mounted on the loading means at one time can be doubled.
