Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an apparatus for automatically discharging at a predetermined position assembly parts of equipment, etc., which are stored in a storage recess of a base in a prescribed posture and are transported intermittently. To provide an automatic ejecting device with a relatively simple structure that can have the functions of sorting correctly assembled parts and poorly assembled parts and ejecting them individually by using automatic ejecting operation. The purpose is to

The configuration of the illustrated embodiment will be explained below.

The drawing shows an embodiment of the automatic ejecting device of the present invention attached to a manufacturing device for a slider for a slide fastener, and shows a completed slider 3 in which a puller 2 is attached to a slider body 1. The slider body 6 is automatically ejected from the storage recess 5 of the base plate 4, and the slider body 6 to which the handle 2 is not attached due to a processing error is automatically ejected from the storage recess 5.

The aforementioned base plate 4 is disk-shaped and has a large number of storage recesses 5, 7, etc. formed at equal intervals on the outer periphery of its upper surface, and is configured to rotate intermittently, and when it stops. At positions corresponding to the storage recesses 5, 7, . The slider is equipped with a device for supplying the handle 2 to the main body 1, a crimping device for the handle attachment portion, etc., and each storage recess 5, 7, etc. is connected to the intermittent rotation of the base 4. The stored slider body material is sequentially processed by
Finally, when the slider 3 is stopped at a position where the automatic ejecting device according to the present invention is attached, the slider 3 stored therein is ejected.

A bracket 8 is disposed above the position corresponding to the storage recesses 5 and 7 when the base 4 is stopped so that it can move forward and backward toward the upper surface 4' of the base 4, that is, it can move up and down in the illustrated example. has been done.

In the illustrated example, the bracket 8 is fixed to a drive shaft 9 that moves up and down in the direction of arrow A by a drive source (not shown).

A discharge arm 10 extending downwardly toward the base 4 is pivotally attached to the bracket 8 by a shaft 11.

The ejection arm 10 has an inverted L-shaped side surface, is pivoted on a shaft 11 at the center of the horizontal arm 12, and has a spring 14 compressed between the arm end 13 and the upper surface of the bracket 8. In the illustrated example, the downwardly hanging discharge arm 10 is biased toward the drive shaft 9 so that it is always in contact with the bracket 8.

The distal end 15, which is the lower end of the ejection arm 10, has bifurcated finger pieces 16,1.
7, and a gap 18 is formed between both finger pieces 16 and 17, and furthermore, on the outside of each finger piece 16 and 17, the periphery is
, 17, the rollers 19, 2 are positioned slightly outward from the lower ends of the rollers 19, 2.
0 is rotatably attached to a shaft 21.

The circumferential surfaces of these rollers 19 and 20 are connected to the discharge arm 1 as will be described later.
This constitutes a guide surface when swinging the 0.

On the other hand, a guide surface 22 is formed on the upper surface 4' of the opposing base 4 directly below the discharging arm 10 hanging down by the force applied by the panel 14.

This guide surface 22 is connected to the roller 1 when the discharge arm 10 is lowered.
When the circumferential surfaces of 9 and 20 come into contact, the discharge arm 10 is swung in a direction opposite to the direction in which the elasticity of the spring 14 acts, as shown by arrow B.

The above-mentioned vertical stroke of the first drive shaft 9 in the direction of arrow A is as follows:
As shown in FIG. 1, the distal end 15 of the discharging arm 10 is guided to the guide surface 22 from the position where the distal end 15 of the discharging arm 10 is spaced upward from the upper surface 4' of the base 4, as shown in FIG. This is the distance between the two positions and the position that is sufficient to swing in the direction indicated by the arrow.

Then, on the base 4 and the machine frame along the swinging trajectory of the tip 15 of the discharge arm 10 indicated by the arrow opening, there is one storage recess 5, 7, etc., as described above, along the swinging direction. Following this recess, a discharge passage 23 located outward in the swinging direction indicated by arrow B is bored.

By the way, the finger pieces 16 and 17 of the ejection arm 10 described above are connected to the shoulders 24 of the handle 2 which protrudes from the upper surface of the slider 3 which is an assembled part stored in the storage recesses 5, 7, . . . The finger pieces 16 and 17 are arranged at positions that project into the swing locus.

That is, the shoulder portion 24 constitutes a selected protrusion among the members that protrude from the upper surface of the slider 3, which is an assembled component.

Now, the slider assembled as shown in FIG. 4 is correctly stored in the storage recess 5, and when the storage recess 5 is located directly under the ejection arm 10 as shown in FIG. When it stops, the driving shaft 9 starts to descend in response to a command from a drive control device (not shown).

After the peripheral surfaces of the rollers 19 and 20 at the tip 15 of the discharge arm 10 come into contact with the guide surface 22 on the base 4 side, the drive shaft 9
, when the ejection arm 10 continues to descend, the tip 15 of the ejection arm 10 begins to swing in the direction shown by the arrow B, and the tip 1
The fingers 16 and 17 of No. 5 are also swung in the same direction.

However, since the protrusion, that is, the shoulder 24 of the handle 2 of the slider 3 protrudes within the swing locus of the finger pieces 16, 17 as described above, the finger pieces 16, 17 do not touch the shoulder during the swing. Part 24
It collides with and presses it in the direction of arrow B.

Therefore, the slider 3 is pushed out from the storage recess 5 toward the discharge path 23, and finally slides completely down into the discharge path 23, completing the discharge.

After the above-mentioned ejection is completed, the drive shaft 9 and the ejection arm 10 rise again to the position shown in FIG. 1, and wait until the storage recess 5 containing the next slider 3 is brought directly below and stopped. It is.

In the embodiment shown in FIGS. 1 to 3, if a defective slider in which the handle 2 cannot be attached to the slider body 1 due to some reason is stored in the storage recess 5, the assembly of this slider 3 The parts include
The shoulder 24 of the handle 2, which is the selected protrusion, does not exist, so even when the fingers 16 and 17 of the ejection arm 10 swing, they do not exert any pressure on the slider, and the defective slider is placed in the storage recess. It will be maintained as it is.

Therefore, in order to eject the defective slider mentioned above, shoulder 2
The selected protrusion that resonates with the slider 4 is another protrusion that the defective slider must have, and an automatic discharging device with the same configuration is installed at the rear of the automatic ejection device shown in FIGS. 1 to 3 in the direction of movement of the base 4. What is necessary is to attach an ejection device and position the other protrusion described above within the swing locus of the fingers of the ejection arm.

5, 6, and 7 show a device for automatically ejecting the defective slider, and the configuration other than the shape of the finger piece 27 at the tip 26 of the ejecting arm 25 is completely the same as in FIG. This is the same device as shown in FIG.

The selected protrusion on the top surface of the defective slider 28 is as follows:
A handle attachment frame 29 is selected, and the finger pieces 27 are shaped to allow the pull attachment frame 29 to protrude within its swing locus.

That is, the ejection arm 10 shown in FIGS.
A gap 18 is provided between the fingers 16 and 17, and the gap 18 allows the handle attachment frame 29 to be located outside the swing locus of the finger pieces 16 and 17.
6 has a series of lower edges formed therein, into which grooves 30 are formed into which the handle attachment frame 29 enters.

Since the rollers 19 and 20 have a wide lower end surface,
is omitted, and the rear surface of the tip is made into an arcuate surface 31 and serves as a guide surface on the discharge arm 25 side.

For this reason, the defective slider 28 that was not ejected by the automatic ejection device shown in FIGS. 1 to 3 is
The automatic ejecting device shown in the figure automatically ejects the liquid by the same operation as that described with reference to Figs. 1 to 3.

The illustrated example is an example applied to a slider manufacturing machine for slide fasteners, but it goes without saying that any assembled part can be automatically ejected as long as it has a protrusion on its top surface. It goes without saying that various structural changes may be made to the structure of each part without departing from the purpose and operation of the invention.

The device of the present invention has the structure and operation as described above, and the drive mechanism is significantly simplified because assembly parts can be automatically ejected simply by moving the bracket on which the ejection arm is pivoted forward and backward toward the base. Since the discharging action is based on the swinging of the discharging arm, the protrusion on the component side that should be located within the swinging trajectory of the finger at the tip of the discharging arm is selected separately for non-defective and non-defective assembled parts. By doing so, not only can the two types be easily sorted, but also the discharge positions can be made separate, and the effects such as sorting and differentiated discharge can be easily performed simply by using different fingers. have.
