Abstract

(57) [Summary] [Structure] A detector 36 in which a spring 34 is interposed between the push-up portion 30 and the slider 12 and which can detect that the interval between the push-up portion 30 and the slider 12 has reached a predetermined value. Provide a limit switch, etc. When the push-up portion 30 moves up, the spring 34 pushes up the plate-shaped component 14. When the uppermost part 14 hits the stop plate 16, the slider 12 cannot be further raised, but when the push-up portion 30 continues to rise, the detector 36 hits the slider 12 to push up the push-up portion 30.
Stops rising. [Effect] When the distance between the slider 12 and the pushing-up portion 30 reaches a predetermined value, in other words, when the spring 34 has a constant length (constant spring force), the lifting of the pushing-up portion 30 stops. Therefore, regardless of the number of the components 14, it is possible to always push up with a constant force. Further, even if the thickness of the component 14 varies, it is sure to operate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 For example, a full-automatic optical fiber fusion splicing device is accompanied by a reinforcing device for the optical fiber splicing part and a reinforcing material supplying device. The present invention relates to a mechanism for pushing up a plate-shaped component in an apparatus for automatically supplying a plate-shaped component such as this reinforcing member. Note that the plate-shaped parts mentioned here include not only thin plate-shaped parts but also thick-walled block-shaped parts.

2. Description of the Related Art The following description will be given using a reinforcing material as a representative of plate-shaped parts. In FIG. 3, 10 is a case, the upper part of which is open. A slider 12 is vertically movable in a case 10, and a large number of reinforcing members 14 are stacked on the slider 12. The reinforcing material 14 has, for example, a strip shape. A stop plate 16 is provided above the case 10. The distance between the stop plate 16 and the upper end of the case case 10 is larger than the thickness of one reinforcing material but smaller than the thickness of two reinforcing materials. A spring 20 is inserted between the bottom plate 18 of the case 10 and the slider 12.

A spring 20 pushes up a group of reinforcing members 14 via the slider 12 until the topmost one hits the stop plate 16. The rod 22 moves forward (to the left in FIG. 3) so that only the uppermost reinforcing member 14 is projected forward and supplied to a reinforcing device (not shown).

[0004]

2. Description of the Related Art As shown in FIG. 4, a slit 24, a sensor 26, and a push-up device 28 are used to push up at a constant pitch (equal to the thickness of the reinforcing material 14).

[0005]

[Problems to be solved by the device]

 In the case of the prior art 1 shown in FIG. 3, (1) When there are many reinforcing members 14, the spring 20 flexes a lot, so that the pushing-up force is strong. Since it does not bend too much, the pushing force is weak. As described above, the method of pushing up only by the spring has a drawback that the pushing force is not constant. (2) Since it is pushed up by the spring, there is a limit to the pushing stroke, and there is also a drawback that too many reinforcing members 14 cannot be accommodated.

In the case of the conventional technique 2 shown in FIG. 4, the variation in the thickness of the reinforcing material 14 cannot be absorbed. For example, when the thickness of the reinforcing material 14 is often thinner than the regulation, even if the reinforcing material 14 is pushed up at a constant pitch, the uppermost reinforcing material 14 cannot be pushed up to a fixed position. On the contrary, if the thickness of the reinforcing material 14 is thicker than the regulation, there is a drawback that the reinforcing material 14 hits the stop plate 16 before being pushed up at a constant pitch and cannot be pushed up.

[0007]

[Means for Solving the Problems]

 As shown in FIG. 1, (1) a spring 34 is interposed between the push-up portion 30 and the slider 12, and (2) it is detected that the distance between the push-up portion 30 and the slider 12 reaches a predetermined value. A detector 36 is provided.

[0008]

【Example】

 Reference numeral 30 in FIG. 1 is a lifting portion. 32 is the push-up machine, which has a mechanical lifting mechanism using a motor. As a detector capable of detecting that the distance between the push-up portion 30 and the slider 12 has reached a predetermined value, for example, a limit switch 36 is used.

The operation of feeding the reinforcing material 14 one by one is as follows. (1) FIG. 2A shows a state immediately after the uppermost reinforcing member 14 is delivered. There is a gap between the top stiffener 14 and the stop plate 16. The spring 34 has a length that balances the weights of the slider 12 and the reinforcing material 14. There is a gap between the limit switch 36 and the slider 12 (designed in this way). (2) As shown in FIG. 2B, when the push-up portion 30 rises, the spring 34 begins to contract, and the slider 12 pushes up the reinforcing material 14 in accordance with the contraction. (3) When the uppermost reinforcing member 14 hits the stop plate 16, the slider 12 can no longer move up, but when the push-up portion 30 continues to move up, the limit switch 36 hits the slider 12. Then, the lifting of the pushing-up portion 30 stops ((c) in the figure). That is, when the distance between the slider 12 and the push-up portion 30 reaches a predetermined value, in other words, when the spring 34 has a constant length (constant spring force), the push-up portion 30 stops rising. (4) As shown in FIG. 7D, the top reinforcing member 14 is pushed out by the rod 22. Then, the state returns to the state of (a). This is automatically repeated below.

[0010]

[Function and effect of the device]

 Since a spring is interposed between the push-up portion and the slider and a detector capable of detecting that the distance between the push-up portion and the slider has reached a predetermined value, (1) As described above. In some cases, the length (spring force) of the spring 34 is always constant during one cycle of pushing up and supplying a plate-like component such as a reinforcing material. Therefore, it is possible to always push up the plate-shaped component such as the reinforcing material with a constant force regardless of whether the number of plate-shaped components such as the reinforcing material is large or small, and regardless of the length of the lifting stroke. (2) Even if there are variations in the thickness of plate-shaped parts such as reinforcing materials, they will definitely operate.
