Description

A one-dimensional alignment feeding unit (ONE-DIMENSIONAL ALIGNING AND FEEDING UNIT)

The present invention relates to a one-dimensional alignment feeding unit for smoothly guiding and feeding a small object, particularly a ceramic capacitor, or the like, in a one-dimensional direction, .

In recent years, a high performance and minute multilayer ceramic capacitor (MLCC) has been developed and used. This multilayer ceramic capacitor has a rectangular parallelepiped shape including a substantially square cross section and is manufactured from, for example, a 0.5 mm short side and a 1 mm long side to a finer 0.1 mm short side and a 0.2 mm long side . However, since it is a rectangular parallelepiped, alignment from a large number of irregularly gathered states was not easy. Further, since it is minute and lightweight, stable grasping, mounting, guiding and the like are difficult, and conveyance of each of the multilayer ceramic capacitors is not easy. In addition, it is necessary to investigate defects in each of the multilayer ceramic capacitors, but it is not easy to inspect the appearance of each multilayer ceramic capacitor for each surface.

Thus, an apparatus for inspecting the four side facets of each multilayer ceramic capacitor while aligning and transporting a plurality of multilayer ceramic capacitors has been proposed (see, for example, Patent Document 1). In this inspection apparatus, a plurality of objects are moved from a supply element to a space having a gradient (a substantially horizontal space), then moved to a one-dimensional tunnel, and aligned and transported while inspecting the side surface.

Japanese Patent Application Laid-Open No. 2009-216698

However, in the inspection apparatus, when the object is moved from the supply element toward the tunnel, the object is first moved to the tunnel through a space having a gradient (a substantially horizontal space). In this case, the object in the supply element shifts from a state where the object is three-dimensionally overlapped into a two-dimensional distribution state in a space (substantially horizontal space) having a gradient, and then moves to a one-dimensional tunnel. Therefore, when the transition from the supply element to the space having the gradient (substantially horizontal space) causes clogging of the object at each stage of movement from the space having the gradient (substantially horizontal space) to the tunnel There is a possibility that the conveyance of the object may not be performed smoothly.

It is an object of the present invention to provide a one-dimensional alignment feeding unit for smoothly feeding a fine conveyed article such as a multilayer ceramic capacitor to a feeding path extending in one-dimensional direction.

(Embodiment 1)

3 is a schematic view showing the overall configuration of the one-dimensional alignment feeding unit 20 according to the first embodiment. Dimensional sorting and feeding unit 20 can be introduced into the supply path 2 which aligns the transported object 1 and extends in one-dimensional direction. The one-dimensional alignment supply unit 20 includes a supply path 2, a carry-object holding tank 3 having a cavity portion 4, a conveying path 5, a conveying path 5 for conveying air to the conveying path 5, (6). The transported article retention tank 3 holds the plurality of transported articles 1 three-dimensionally while stirring by the airflow supplied from the air supply pipe 5 into the hollow portion 4. [ Further, the conveying engine 5 is provided on any one surface of the conveyed article holding vessel 3 and supplies the airflow into the cavity portion 4 of the conveyed article holding vessel 3. The supply path (2) is a supply path extending in at least one one-dimensional direction provided on the side surface of the transported matter holding tank (3).

As shown in Fig. 2, each of the articles 1 is guided and supplied into the supply path 2 by the airflow in the hollow portion 4 of the article holding jig 3. According to the one-dimensional alignment supply unit 20, the individual conveyed articles 1 are aligned by the alignment effect by the airflow in the hollow portion 4 of the conveyed article holding jig 3, To the supply path 2 so as to smoothly supply it. 2 shows an example of the sorting effect by the airflow of the conveyed object 1, and the present invention is not limited to this.

Hereinafter, the constituent members constituting the one-dimensional alignment feeding unit 20 will be described.

<Retention of retentate>

It is preferable that the cavity portion 4 of the return material holding jig 3 has a dimension at least 10 times larger than each dimension such as the length, width, and height of the transported object 1. [ As a result, stirring by the air current of the transported object 1 is sufficiently performed, and the alignment effect of the transported object 1 on the supply path 2 can be obtained.

<Supply Department>

Further, the replenishment section 8 may be provided on the upper surface of the transported article retention tank 3. [ A plurality of the transported articles 1 are supplied to the cavity portion 4 by being vertically provided above the cavity portion 4 of the transported article retention tank 3 by the supply portion 8.

<Supply path>

As shown in Figs. 1 (a) and 1 (b), the supply path 2 is a supply path extending in at least one one-dimensional direction. The number of supply paths 2 is not limited to one, but may be two or more, for example, four as shown in Fig. 1 (a). It is also preferable that the supply path 2 is provided on a side vertically above the bottom surface of the transported article holding tank 3 by a predetermined distance. It is preferable that the predetermined interval from the bottom surface is at least an interval of at least one of the width, length and height of the conveyed object 1. As a result, it is possible to obtain a sorting effect by the three-dimensional airflow including the direction from the bottom surface of the cavity 4 of the transported article holding jig 3.

Further, the supply path 2 has a size such that the size of the cross-sectional area perpendicular to the transport direction is capable of transporting the transported article 1 in the one-dimensional direction. Specifically, it is a necessary condition that the size of the cross-sectional area perpendicular to the transport direction is larger than the cross-sectional area of the transported object 1 in the transport direction. In addition, it is preferable that the average distance between the supply path 2 and the side surface of the transported article 1 to be transported is 5% or more of the width, length and height of the transported article 1 in its sectional shape. It is preferable that the opening of the supply path 2 to the supply path 2 provided on the side surface of the transported article retention tank 3 is larger than the length of the shorter side of the transported article 1 and smaller than the longer side of the transported article 1 .

The shape of the cross section perpendicular to the conveying direction of the supply path 2 may be a circular shape, a rectangular shape, a triangular shape, or a polygonal shape. The cross-sectional shape perpendicular to the conveying direction of the supply path 2 is preferably a cross-sectional shape perpendicular to the conveying direction of the conveyed object 1 and a topography. By making the cross-sectional shape of the supply path 2 and the cross-sectional shape of the transported object 1, each surface of the transported object 1 and the supply path 2 can correspond to each other. When the cross-sectional shape perpendicular to the conveying direction of the conveyed object 1 is a rectangular shape, it is preferable that the cross-sectional shape perpendicular to the conveying direction of the supply path 2 is a rectangular shape. As a result, the side surface of the rectangular parallelepiped article 1 and the respective planes of the supply path 2 can be transported in correspondence with each other, so that each side surface of the transported article can be easily identified.

2, the size of the opening of the supply path 2 with respect to the transported article retention tank 3 is not less than the size of the short side of the transported article 1 and not more than twice the size of the short side desirable. In the case where the object 1 is a multilayer ceramic capacitor, when the short side is W, the long side is 2W which is twice the short side. Therefore, when the opening is formed into a rectangular shape, the range of the dimension of one side is equal to or more than W and equal to or less than 2W. By making the size of one side of the opening of the supply path 2 smaller than or equal to twice the short side W of the multilayer ceramic capacitor as the transported material (<2W), the long side direction of the transported object 1 is shifted in the transport direction of the supply path 2 It is easy to carry out the conveyance smoothly. In addition, if the opening is larger than the length (2W) in the long side direction, there is a possibility that the long side direction of the transported article 1 becomes perpendicular to the transport direction of the supply path 2, thereby causing clogging during transportation.

Further, it is preferable that the supply path 2 is held at a lower pressure than the inside of the cavity portion 4 of the transported article retention tank 3. A pressure reducing portion may be provided in order to keep the supply path 2 at a pressure lower than that of the transported matter holding tank 3. The pressure reducing portion may be constituted by, for example, a vacuum pump or the like. As described above, the conveyed object 1 can be easily introduced into the supply path 2 from the transported article retention tank 3 by holding it at a lower pressure than the transported matter holding tank 3.

(Embodiment 2)

Fig. 4 is a schematic view showing the overall configuration of the one-dimensional alignment supply unit 20a according to the second embodiment. The one-dimensional alignment supply unit 20a is different from the one-dimensional alignment supply unit 20 according to the first embodiment in that when the transported object 1 is clogged in the supply path 2, (10) for returning to the conveyed article holding tank (3) to eliminate clogging. This back-up mechanism 10 feeds back the transported product 1 clogged in the opening from the supply path 2 or the transported article holding tank 3 to the supply path 2 to the transported matter holding tank 3 to eliminate clogging .

The back-feed mechanism 10 is composed of a pressurizing section 12 for increasing the pressure of the return-object holding vessel 3. Further, the back-feeding mechanism 10 may be provided with a clog detecting section 11 for detecting clogging of the transported article 1 to be transported.

The clog detecting unit 11 includes an irradiating unit 13 for irradiating light from the upper part of the supply path 2, a reflected light detecting unit 14 for detecting reflected light by the transported object, And a control unit 15 for judging whether or not there is an abnormality. In this case, when the reflected light from the transported object 1 is continuously detected in the reflected light detection unit 14 and is not interrupted, the control unit 15 may judge that clogging is occurring.

The pressurizing portion 12 may be constituted by bombs such as compressed air, compressed nitrogen, helium or the like. Regularly or when the clogging detecting section 11 detects clogging in the supply path 2 of the transported object 1, the inside of the supply path 2 is pressurized by compressed air or the like from the pressing section 12 , The conveyed object (1) clogged in the supply path (2) is fed back to the transported matter holding tank (3) to eliminate clogging. The pressurization of the supply path 2 by the pressurizing section 12 is not limited to the case of continuous pressurization but may be performed in a pulse shape once or plural times.
