Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for sorting the front and back sides of a punched disc part, such as a washer, which is punched out from a plate by a press.

For example, it is relatively easy to visually tell the front and back of Watsunoya that has been punched out using a press.
The determination is made as follows. That is, as shown in FIGS. 1 and 2, the washer 1 that has been scooped out by a press has a sag a and a sheared portion on the outer periphery of the cross-sectional box when the 11th person is present.

The broken portion C2 burr d is continuously formed. For this reason-
At the age of age, the A side is the robe, and the burr D side is the back (-).

Therefore, when using this type of washer 1, the function]
Or, from a Shinsho perspective, it becomes necessary to select the front and back sides for use. However, as mentioned above, visual inspection of the front and back requires a great deal of labor, and this is a major bottleneck in attempting to automate the assembly work. In addition, there are manual sorting errors such as misunderstandings and inadvertent mistakes, and it is important to ensure that there are no functional or design defects in assembled products.

The present invention addresses the above-mentioned problems, and its purpose is to provide a front-back sorting device for ladle-cut disc parts that can automatically sort the front and back sides of a punched-out disc part that has been punched out using a press. There is a particular thing.

In order to achieve the purpose of the present invention,
A gutter with a cross-section shape is formed with the lll plate, and by arranging this gutter at an angle, it is possible to roll the disc part in the gutter while standing almost vertically, and the longitudinal direction of the gutter is In the middle part, a sorting part having an angular cross section formed by opening one side of the plate 1 (11) was provided.

When looking at the cut surface of the outer periphery of a blanked disc component (generally produced by pressing), there is a sag on the surface side and a burr on the kIll. There is a sheared part and a broken part in between, and the outer periphery has a tapered shape with the back side tapering when viewed as a whole. For this reason, when a disk component is stood vertically and rolled on its front 11 surface, it rolls not in a surface line trajectory but in a curved trajectory along the taper. The present invention utilizes such rolling characteristics of the scooped disc component.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6. The basic configuration is that the front/back sorting device 2d and the gutter 3 according to the embodiment of the present invention were installed by removing the parts.

This gutter 3 has a bottom plate 4 made of a board, and 1MII roots 5 A and 5 B erected on both sides along the longitudinal direction of this bottom plate 4.
More composed and cross-sectional! ] shaped like a letter. Is the interval between the two 1lli plates 5A and 5H forming this 2-shaped cross section a disc part that is sorted by 1? 11 should be able to roll while standing vertically. In addition, in the middle part of this gutter 3id in its length 1 force direction, one plate 5B on one side of the side plates
An open part 6 is provided by cutting out the opening part 6, and the remaining side 15A and the bottom plate 4 form a sorting part 7 having an angular cross-section. With this sorting section 7 as a boundary, one side is an introduction section 8 for the disk component, and the other side is an output section 9. The gutter 3 configured in this manner is tilted onto the support stand 11 via the support 10 so that the introduction part 8 is on top. The support column 10 is configured so that its vertical height can be adjusted. In addition, the gutter 3
A receiving box 12 is installed at -F of the sorting section 7, and a support stand 11
Fixed.

Next, the sorting of the disk components 1 by the front and back sorting device 2 configured as above will be explained.

One disc part 1 is indiscriminately put into the introduction part 8 of the gutter 3 without being separated. Attach both ff1ll to the disk part 1 that has entered the introduction part 8
Since it is guided by A and 5B, it starts rolling downward without MpIS. This IL Air disk part 1
If the expression 1 is on the 1lli board 5A side, it will be a circle ↑
91 (Due to the j-pa due to the outer circumferential shape of the product, the disc part rolls in contact with the side plate 5B side, and if the front plate 1 faces the side plate 5B 11111, it will roll on the side plate 5A side. Rolling close to each other.

When the disc parts 1 rolling through the introduction part 8 in this way come to the sorting part 7, the disc parts IA rolling around the side plate 5A as shown in FIG. rolling around,
Enter the derivation section 9. On the other hand, as shown in Fig. 6, the disc part IB that has rolled in contact with the side plate 5B loses its support due to the open part 6 of the side plate 5B in the sorting section 7, and therefore moves in the direction of drawing a curved trajectory. Start moving freely. However, since the width of the shield plate 4 of the gutter 3 is slightly wider than the plate +1 of the disk component 1, the disk component IB shown in FIG. As shown by the line arrow, it passes through the gutter 3 and enters the receiving box 12.

As described above, according to the embodiment of the present invention, the front and back sides of the disc part 1 can be sorted by simply rolling the front and back sides of the disc part 1 over the gutter 3 indiscriminately, so the labor is reduced compared to visual sorting. It is reduced in size and can be used as an automatic sill for fine-grain work.

By the way, some of the nil disk parts 1 do not necessarily have an outer circumferential shape as shown in FIG. 2 due to delicate punching operations, and some of them do not have a taper formed on the outer circumference. Normally, we would like to exclude such disk component ICs, but since they roll without contacting the side plate 5A side, the side plate 5f311111, or both control plates, among them...those that roll in contact with the plate 5B... There is an inconvenience that the other parts enter the extraction section 9 and are sorted and mixed with the disc parts as shown in FIG. 4.

The front/back sorting device 2 shown in FIGS. 7 and 8 was defeated in this small-scale 1ζ combination. That is, the basic structure is the same as that of the embodiment shown in FIG. 3, and the components are also the same. Therefore, although repeated explanation will be omitted, the difference from the previous embodiment is the planar shape of the gutter 3A. Door 1j, turn the gutter 3A to the bottom fl so that the intervening part 6 side protrudes.
It was curved in the width direction of i and 4. This curve is formed from the selection part 7 to the lead-out part 9 of the gutter 3A, and its curvature is likely to be a curve of 61 In order to do so, Il of gutter 3A
The rolling speed of the disk component 1 can be adjusted by changing the p-angle.

Since the gutter 3A was bent from the sorting part 8 in this way, among the disc parts 1 which were introduced into the introduction part 8 without any difficulty, the disc part IA rolled while the back was in contact with the input side of the side plate 5. has the property of drawing a curved trajectory, so the selection unit 7
It rolls along the curvature of and enters the lead-out portion 9. On the other hand, the disk component IB rolling while its back side is in contact with the steel plate 5B side falls into the receiving box 12 at the sorting section 7 in the same manner as in the previous embodiment.

In addition, since the disk component IC with no taper formed on the outer periphery increases the self-propelling inertia by +44 by rolling in the introduction section 8, from outside to gutter 3].

In this way, even if the shape of the outer periphery is different from the outer periphery shape of a general disk component, it is possible to exclude it and perform front and back sorting.

In addition, although the above-mentioned expansion is made by curving the gutter 3A from the sorting part to the lead-out part 9, this bending method is not limited to this, and the same effect can be obtained even if the entire gutter 3A is bent with the same curvature. It can be effective.

By the way, in each of the above embodiments, the supply of the disc part 1 to the introduction part 8 of the gutter 3, 3A and the carrying out of the disc part 1 from the lead-out part 9 were not explained to Bamboo, but the introduction part 8 side By providing a funnel-shaped supply tool in the holder and a storage trough similar to the troughs 3 and 3A in the outlet section 9, it becomes possible to sort out the disk parts 1 widely.

As explained above, according to the present invention, a cross-section-shaped gutter is installed to allow the punched disc parts to stand almost vertically and be transferred, and a cross-section is formed in the longitudinal middle part of this gutter. Using the α provided in the character-shaped sorting section, simply supply the punched disk parts from the upper end of this gutter (1 μm 1) to the wholesaler and roll them to automatically sort and separate the front and back of the figurine parts. I can do it.
