[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, in which parts corresponding to those in FIG. 5 are assigned the same reference numerals, reference numeral 20 denotes a mounting apparatus, which has the same configuration as that of the mounting apparatus 1 except for the configuration of bulk cases 23 attached to the respective bulk feeders 2. Have been.

In practice, as shown in FIGS. 2A and 2B, the bulk case 23 has a substantially rectangular parallelepiped transparent plastic having an internal space 24A capable of accommodating a plurality of chip components 9 therein. A case body 24 made of a material is provided, and a mounting portion 24B is provided at a distal end portion of the case body 24.

The bulk case 23 has a mounting portion 24B.
Is inserted into an intake port 14A (FIG. 6) provided in the alignment section 14 of the bulk feeder 2, so that an access port 40 formed in accordance with the size of the chip component 9 in the mounting section 24B, and the bulk feeder 2 With the inlet 14A of the bulk feeder 2 aligned.
It is designed so that it can be attached and fixed.

On the side surface of the case body 24, a slide shutter 41 (shown by a broken line) is slidable integrally with the slider 42 in an upward direction indicated by an arrow a and a downward direction opposite thereto.
By moving the slider 42 in the upward direction indicated by the arrow a, the internal space 24A of the bulk case 23 and the internal passage of the alignment section 14 of the bulk feeder 2 communicate with each other, and the slider 42 is stored in the internal space 24A. The plurality of chip parts 9 are put in and taken out of the inlet 40 and the inlet 14A of the alignment unit 14.
And can be supplied to the bulk feeder 2.

Further, the internal space 24A of the case body 24
Has a substantially rectangular parallelepiped inner wall, and has an internal space 24A
Is formed in a taper K that gradually narrows from the predetermined position toward the inlet / outlet 40.
When the component 3 is attached to the alignment portion 14 of the bulk feeder 2, the chip component 9 can be supplied through the access port 40.

In addition to this configuration, in the case of the bulk case 23, a partition portion 45 is provided in the internal space 24A of the bulk case 23 so as to partition the bulk feeder 2 in a direction perpendicular or substantially perpendicular to the moving direction.

In this way, in the bulk case 23, the movement of the chip component 9 housed in the internal space 24A can be suppressed by the partition portion 45, and thus the transfer table 5 can be kept in a state of being mounted on the bulk feeder 2. 24A of internal space with movement start and stop operation
The plurality of chip parts 9 stored in the internal space 24A
When it is swung in the width W direction, the impact force when the chip component 9 stored in the internal space 24A collides with the inner wall is reduced by half, so that the chip component 9 can be prevented from being damaged. ing.

In the case of this embodiment, the bulk case 23
The partitioning part 45 is integrally formed with the inner wall substantially in the center of the width W in the internal space 24A of the bulk case 23, thereby fixing the manufacturing of the partitioning part 45 by attaching a separate partition plate to the inner wall. As compared with the case, the process can be easily performed as much as the step can be omitted.

In the case of this embodiment, the partition 45 of the bulk case 23 is located in the inner space 24A.
By having a length from 4C to a position immediately before the start of the taper K, the chip parts 9 stored in two chambers can be supplied by the partition part 45 without being clogged at the tapered K portion. It has been made like that.

In the above configuration, the mounting apparatus 20 has the bulk feeder 2 mounted and fixed on the upper surface 5A of the transfer table 5, and the movement of the transfer table 5 in the direction indicated by the arrow X starts and stops, and the bulk feeder 2 is moved. 2
When the plurality of chip parts 9 stored in the bulk case 23 attached to the inner space 24A move in the direction indicated by the arrow X in the internal space 24A, the distance by which the chip parts 9 move by the partition part 45 is larger than that in the related art. About half.

Thus, in the bulk case 23, the chip component 9 housed in the internal space 24A only moves in the space between the inner wall and the partition 45, and the impact when the chip 9 collides with the inner wall and the partition 45 is formed. Since the force can be reduced, it is possible to prevent the chip parts 9 from being damaged due to the movement start and stop operations of the transport table 5.

Further, in the bulk case 23, the internal space 24A can suppress the movement of the chip components 9 by the partition portion 45, so that friction between the chip components 9 is reduced, and the electrode surface of the chip component 9 is reduced. Oxidation and blackening can be prevented.

According to the above configuration, the partitioning section 45 for partitioning the internal space 24A of the bulk case 23 in a direction perpendicular or substantially perpendicular to the direction of movement of the transfer table 5 allows the transfer table 5 to start and stop moving. Bulk case 23 capable of preventing breakage of chip component 9 caused by operation
Can be realized.

In the above-described embodiment, a case has been described in which the substantially rectangular bulk case 23 is applied as the component supply case. However, the present invention is not limited to this, and the present invention is not limited to this. You may make it apply to component supply cases of various shapes.

In the above-described embodiment, the partition part integrally formed in the internal space 24A as partitioning means for partitioning a part or all of the internal space of the case main body in a direction perpendicular or substantially perpendicular to the moving direction of the supply object. 45 has been described, but the present invention is not limited to this. For example, a partition plate 50 having a predetermined shape as shown in FIG. A separate partitioning means made of various other materials or shapes such as a saw blade-shaped partitioning plate 60 as shown in FIG. 4 may be applied.

For example, the partition plate 50 shown in FIG. 3 is made of a flexible film-like material, and is formed in a shape that can be easily inserted through the slot of the conventional bulk case 6. As a result, when the partition plate 50 is inserted into the bulk case 6 in a state of being bent by the user in the conventional bulk case 6, it expands in the internal space due to its flexibility and returns to the original shape. The movement of the chip component 9 can be suppressed to prevent breakage.

Further, as shown in FIG. 4, the partition plate 60 is made of a hard sheet, and is formed in a saw blade shape which can be easily inserted through a conventional bulk case 6. One end and the other end of the partition plate 60 are selected to be smaller in width than the entrance. Thus, even in the conventional bulk case 6, the partition plate 60 can be easily inserted into the bulk case 6 by the user according to the saw blade shape, and the movement of the chip component 9 in the internal space can be suppressed to prevent breakage. It has been made like that. By the way, the partition plate 60 inserted into the bulk case 6 has a saw blade shape inside, so that it can be easily taken out from the entrance.

Further, in the above-described embodiment, a case has been described in which the partition portion 45 is integrally formed in the internal space 24A of the bulk case 23, but the present invention is not limited to this, and the inside of the bulk case 23 is not limited to this. A plurality of partitions may be integrally molded in the space 24A. As a result, the movement of the chip component 9 is further suppressed, so that it is possible to further prevent the chip component 9 from being damaged and the electrode surface from being oxidized and blackened.

Further, in the above-described embodiment, the case has been described where the bulk feeder 2 of the mounting apparatus 20 is applied as a component to be supplied to which a component supply case for supplying an electronic component is connected in a predetermined state. The present invention is not limited to this, and may be applied to various other devices such as an assembly device.
