[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shape sorter for performing size selection and appearance selection of parts having a large diameter portion and a small diameter portion.

[0002]

[Prior Art]

 For example, as shown in FIG. 11, in assembling a small coil device, a shaft portion 21 having a small diameter portion (dimension φ2) like a ferrite core and a collar having a large diameter portion (dimension φ1) provided at both ends thereof. A component 10 having a shape including a portion 22 is used, and a coil 23 is wound around the shaft portion 21 as shown in FIG. 12 to assemble a coil device 24.

By the way, when the component 10 having such a shape is used, various sizes are prepared according to the required characteristics of the coil device 24. Further, even as a part for satisfying one characteristic, a part having a large variation in the dimension φ1 of the large diameter portion and the dimension φ2 of the small diameter portion is manufactured.

Therefore, when assembling the coil device 24, it is necessary to perform size selection and appearance selection of the component 10 to exclude defective components in advance.

Conventionally, such non-defective products are selected manually, and the dimensions of each component are measured one by one, and the shape is visually confirmed to perform appearance selection.

[0006]

[Problems to be solved by the device]

 As described above, since the dimensional selection and the external appearance selection of the parts have been performed manually in the related art, there is a problem that the number of selection processes increases and the cost increase cannot be avoided.

The present invention has been made in consideration of the above problems, and an object thereof is to provide a shape sorter that automatically and continuously performs size selection and appearance selection.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a container part for accommodating parts having a large diameter part and a small diameter part, a vibration source for vibrating the container part, and the parts arranged along the periphery of the container part. In a shape sorter having a transfer section that moves to the outside of a container section by vibration, a first gate section that is arranged at an intermediate position of the transfer section and selects a large-diameter section of the component, and another transfer section of the transfer section. It has a second gate portion arranged at an intermediate position for selecting a small diameter portion of the component.

[0009]

[Action]

 According to the structure of claim 1, in the parts sequentially supplied from the container part to the transfer part by vibration, the large-diameter part is first sorted in the first gate part. Next, the parts that have passed through the first gate portion are selected for the small diameter portion at the second gate portion.

According to the second aspect of the present invention, the parts to be sequentially supplied from the container part to the transfer part are selected at the large-diameter part first, so that the objects to be selected thereafter are narrowed down. Can be done easily.

According to the structure of claim 3, not only the small-diameter portion is selected by the second gate portion, but also the outer appearance is selected, so that the selection can be performed efficiently.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a shape sorter of the present invention. The shape sorter 1 of the present embodiment is a container portion for accommodating a component 10 such as a ferrite core having a large diameter portion and a small diameter portion. 2, a vibration source 3 that is integrally mounted below the container portion 2 and vibrates the container portion 2, and a sorting device that is arranged along the periphery of the container portion 2 and moves the component 10 to the outside of the container portion 2 by vibration. It is also provided with a transporting section 4 composed of a truck, and further with a shape selecting section 5 for performing size selection and appearance selection of parts.

FIG. 2 shows the details of the shape selecting section 5, in which the peripheral section along the length direction of the cross-section-shaped selecting track 4 A forming the conveying section 4 is directed in the downstream direction. The first gate portion 6 for sequentially selecting the large diameter portion 22 of the component 10 and the second gate portion 7 for similarly selecting the small diameter portion 21 are arranged. It should be noted that the second gate portion 7 also acts to perform appearance selection as described later. 9 is a case for storing the selected parts.

As shown in FIGS. 3 and 4, the first gate portion 6 is composed of a gate member 6B having a protruding piece 6A that covers the sorting track 4A, and this gate member 6B is arranged in the height direction via a screw 6D. H is adjustably fixed to the sorting truck 4A. The distance L1 between the protruding piece 6A and the sorting track 4A is set to a value suitable for sorting the large diameter portion 22 of the component 10. That is, the dimension of L1 is set to the large diameter portion plus side tolerance. As a result, the parts 10 on the standard plus side can be selected. The distance L1 can be freely adjusted by the screw 6D.

As shown in FIGS. 5 and 6, the second gate portion 7 is composed of a gate member 7A having a U-shaped cross section, which faces the sorting track 4A, and the gate member 7A is elevated via a screw 7C. The height direction H is adjustably fixed to the sorting truck 4A. The distance L2 between the gate member 7A and the sorting track 4A is set to a value suitable for sorting the small diameter portion 21 of the component 10. That is, the dimension of this L2 is set to the small diameter portion plus side tolerance. As a result, the parts 10 on the standard plus side can be selected. Further, in the second gate portion 7, not only the small-diameter portion 21 is selected, but also defective parts 10A and 10B in which the middle portion of the small-diameter portion 21 is broken as shown in FIG. Also, as shown in FIG. 9, a defective part 10C in which the small diameter part 21 is unmachined, and further, an external appearance for removing the defective part in which the small diameter part 21 and the large diameter part 22 have a large tolerance dimension are selected. It is supposed to be done. The distance L2 can be freely adjusted by the screw 7C.

Next, the operation of this embodiment will be described.

The vibration source 3 is driven in a state where a large number of parts 10 having a large diameter portion 22 and a small diameter portion 21 as shown in FIG. As a result, the vibration is transmitted to the container unit 2, and the component 10 gradually moves onto the sorting truck 4A of the transport unit 4 while repeating its rotation and self-propelling. At this time, due to the structural characteristics of the component 10, the shaft portion 11 is in the most stable state over the sorting truck 4A and is sequentially moved by vibration.

The component 10 that has moved in this way first reaches the first gate portion 6. Then, only the component 10 having the desired large-diameter portion dimension φ1, that is, only the component within the standard plus-side tolerance range as described above, has the protruding piece 6A and the sorting track as shown in FIGS. 3 and 4. It moves ahead through the gap L1 with 4A. At this time, the component 10 whose large-diameter portion dimension φ 1 is out of the allowable range of the standard is blocked by the protruding piece 6A or becomes unstable and falls into the lower case 9 and cannot proceed further. .. Parts that are stopped by being blocked by the first gate portion 6 are handled by an operator and stored in the case 9.

The component 10 that has passed through the first gate portion 6 reaches the second gate portion 7. Then, only the component 10 having the desired small diameter portion dimension φ2, that is, only the component within the tolerance range on the plus side of the standard as described above, has the gate member 7A and the sorting track 4A as shown in FIGS. And moves forward through the interval L2. At this time, the part 10 whose small diameter portion size φ2 is out of the allowable range of the standard cannot be advanced.

Further, in the second gate portion 7, as described above, the parts having a defective external appearance as shown in FIGS. 7, 8 and 9 are also selected and fall into the case 9. Alternatively, it is housed in the case 9 by a worker. In this way, in the second gate portion 7, since the appearance selection is performed together with the selection of the small diameter portion, the selection work can be efficiently performed.

In this way, only the component 10 in which the three conditions of the large-diameter portion size φ1, the small-diameter portion size φ2, and the appearance are all within the allowable range of the standard, is the first gate portion 6 and the second gate portion 6. After passing through the door portion 7, it is selected as a good product.

FIG. 10 shows a schematic structure of the appearance of the shape sorter 1 of this embodiment. Since the case 9 is arranged below the sorting truck 4A, defective parts can be smoothly sorted and stored.

According to the present embodiment as described above, the first gate portion 6 and the second gate portion 7 are arranged around the lengthwise direction of the sorting truck 4A that constitutes the transport portion 4, and the sorting gate 4A and the second gate portion 7 are arranged in each of them. Therefore, the large-diameter portion, the small-diameter portion, and the external appearance of the component 10 that moves due to vibration are selected, so that the component 10 can be automatically and continuously moved only by moving the transport unit 4. It is possible to perform size selection and appearance selection.

Further, by disposing a plurality of the transport units 4 in such a shape sorter, the sorting processing capacity can be further expanded.

Since the distances L1 and L2 between the first and second gate portions 6 and 7 are adjustable, it is possible to deal with components of various standards.

[0027]

[Effect of the device]

 As is clear from the above description, according to the present invention, since each gate section for performing size selection and appearance selection of a part is arranged at an intermediate position of the movement path of the part moved by the vibrating part, the part is automatically The size and the appearance can be selectively and continuously selected.
