Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for supplying a C-ring to a magazine of a C-ring fastening device.

[Conventional technology]

FIG. 13 is a schematic diagram showing a C-ring fastening device. In the figure, 1 is the C-ring fastening device body, 2
1 is a magazine attached to the main body 1, 3 is a C-ring feeding member, 4 is a hole provided in the C-ring feeding member 3, 5 is a spiral spring whose one end is attached to the main body 1; The end is attached to a C-ring feeding member 3, and the C-ring feeding member 3 and the spiral spring 5 constitute a C-ring feeding device for feeding the C-ring supplied to the magazine 2.

Conventionally, in order to supply C-rings to such a C-ring fastening device, as shown in FIG. 14 and FIG. By gluing them together, a C-ring assembly 17 is formed by integrating a large number of C-rings 6, and by moving the feeding member 3 against the spiral spring 5, the feeding member 3 is removed from the magazine 2. In this state, if the C-ring assembly 17 is loaded into the magazine 2 and then the magazine 2 is inserted into the hole 4, the force of the spiral spring 5 is applied to the C-ring assembly 17 via the feeding member 3. The C-ring assembly 17 is then fed into the fastener.

[Problem that the invention attempts to solve]

However, when loading the C-ring assembly 17 into the magazine 2, the length of the C-ring assembly 17 cannot be greater than the length of the magazine 2, so it is difficult to load a large number of C-rings 6 at once. This increases the number of times the C-ring assembly 17 must be loaded, making the C-ring fastening work troublesome. Also,
Since the C-ring assembly 17 has a large number of C-rings 6 glued together with adhesive tape 7, the C-ring assembly 17
There is a risk that the C-ring 6 may fall off from the adhesive tape 7 during packaging and transportation.

This invention was made in order to solve the above-mentioned problems, and provides a C-ring supply device for a C-ring fastening device that can load a large number of C-rings at once and is free from the risk of C-rings falling off. The purpose is to

[Means for solving problems]

In order to achieve this purpose, this invention provides a device for supplying a C-ring to a magazine of a C-ring fastening device, which has flexibility, has a width smaller than the inner width of the C-ring, and has an opening width of the C-ring. A long plate-shaped C having a width larger than that of the magazine and having one end attached at a higher position than the magazine.
A ring holding part and a connecting part with the magazine provided at the other end of the C ring holding part are provided.

[Effect]

In this C-ring supply device of the C-ring fastening device, after the C-ring holding part holds the C-ring, if the connecting part is connected to the magazine, the C-ring is fed from the C-ring holding part to the magazine by its own weight. be able to.

〔Example〕

Figure 1 shows the C-ring fastening device according to this invention.
FIG. 2 is a plan view showing the ring supply device, FIG. 2 is a front view, and FIG. 3 is a cross-sectional view taken along line A-A in FIG. In the figure, reference numeral 8 denotes a long plate-shaped C-ring holding part made of spring steel, and the width a of the holding part 8 is smaller than the inner width b of the C-ring 6 and larger than the opening width c of the C-ring 6. Reference numeral 9 designates a connection part with the magazine 2 provided at the end of the C-ring holding part 8, 16 a hole provided in the connection part 9, and 10 a ring member attached to the end of the C-ring holding part 8. .

FIG. 4 is a plan view showing a state in which the C-ring supply device of the C-ring fastening device shown in FIGS. 1 to 3 is connected to the magazine 2, and FIG. 5 is a front view thereof. In the figure, 11 is a groove provided at the end of the magazine 2, 12 is a hole provided in the magazine 2,
The connecting part 9 is inserted into the groove 11, and the hole 16,
A connecting pin 13 is inserted into 12.

In such a C-ring supply device, the sixth
As shown in the figure, with a large number of C-rings 6 (not shown) held in the C-ring holding part 8, the connecting part 9
If the C-ring 6 is connected to the magazine 2 and the end of the C-ring holding part 8 is supported by a ring member 10 (not shown) at a position higher than the magazine 2 such as a wall, the C-ring 6
can be supplied to the magazine 2 by its own weight. In this state, by moving the feeding member 3 against the spiral spring 5 while passing the C-ring 6 into the hole 4, the C-ring 6 can be fed to the fastening portion by the C-ring feeding device. When the C-ring 6 held by the C-ring holding part 8 runs out, the C-ring supplying device is removed from the magazine 2, and then the connecting part 9 of another C-ring supplying device holding the C-ring 6 is removed. Connect to magazine 2.

In this way, in this C-ring supply device, since the C-rings 6 are held in the long plate-shaped C-ring holding portion 8, a large number of C-rings 6 can be loaded at once regardless of the length of the magazine 2. is possible. Furthermore, there is no risk that the C-ring 6 will fall off from the C-ring holding portion 8. Furthermore, the C-ring supply device can be used many times, and there is no need to use adhesive tape 7 as in the past. Also,
Since the C-ring holding portion 8 is made of flexible spring steel, the C-ring fastening device can be freely moved even when the C-ring supply device is connected to the magazine 2. Furthermore, since the C-ring 6 can be fed into the magazine 2 by its own weight, no power is required to feed the C-ring 2.

FIG. 7 is a plan view showing a part of the C-ring supply device of another C-ring fastening device according to the invention, FIG. 8 is a front sectional view, and FIG. 9 is a side view. In the figure, 14 is a connecting member attached to the connecting part 9, and 15 is a hole provided in the connecting member 14.

FIG. 10 is a plan view showing a state in which the C-ring supply device shown in FIGS. 7 to 9 is connected to a magazine;
FIG. 11 is a front sectional view, and FIG. 12 is a side sectional view. In the figure, 18 is a hole provided at the end of the magazine 2, and the connecting pin 13 is inserted into the holes 15, 16, and 18.

In addition, in the above-mentioned embodiment, the case where the C-ring holding part 8 is made of spring steel was explained, but the C-ring holding part 8 is made of spring steel.
The ring holding portion may be made of flexible resin or the like. Further, the connecting portion is not limited to the structure of the above-described embodiment. Furthermore, when manufacturing the C-ring 6, if the connecting part 9 is connected to the C-ring manufacturing apparatus and the C-ring 6 is directly held by the C-ring holding part 8 from the C-ring manufacturing apparatus, the C-ring holding part 8
There is no need to hold the C-ring 6 in place.

[Effect of idea]

As explained above, in the C-ring supplying device of the C-ring fastening device according to this invention, it is possible to load a large number of C-rings at once, so the number of times of loading is reduced, and the C-ring fastening work can be reduced. It can be done easily. Furthermore, since there is no risk of the C-ring falling off, handling such as packaging and transportation becomes easier, and loss of the C-ring is prevented. Furthermore, the C-ring supply device can be used many times, and it is economical because it does not require the use of adhesive tape as in the past. Furthermore, since the C-ring can be fed into the magazine by its own weight, no power is required to feed the C-ring. In this way, the effects of this invention are remarkable.
