Abstract

PROBLEM TO BE SOLVED: To improve the transfer speed of a work in a transfer device in which a chuter having a tunnel type passage is vibrated in a direction inclined to a horizontal plane to transfer the work. SOLUTION: A chuter 12 is divided into an upper chuter 14 and a lower chuter 15. A passage 13 is formed on the surface in which the upper and lower chuters 14 and 15 are connected together. The inclined positions of leaf springs 16 and 17 for supporting the upper and lower chuters 14 and 15 are different from each other. When electric current is intermittently supplied to a solenoid coil 19, the upper and lower chuters 14 and 15 come into tight contact with each other to move vertically, and horizontally move in opposite directions to each other. A work W flown due to the forward movement of the lower chuter 15 is pushed forward by the upper chuter 14 moving forward, so that the flying distance of the work W per cycle is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibratory transfer device used for transferring (transporting) various works (objects to be transferred) such as chip-shaped electronic components in a linear direction.

[0002]

2. Description of the Related Art FIGS. 7 and 8 show a linear feeder device for transferring a large number of works in a straight line without changing the order.
The following is used. That is, this transfer device 1 attaches a shooter 3 made of a magnetic material having a tunnel-like passage 2 having a rectangular cross section to a base 5 via a leaf spring 4 which is inclined rearwardly in a side view. An electromagnetic coil (electromagnet) 6 for applying vibration is attached to the shooter 3.

When the electromagnetic coil 6 is intermittently energized in a short cycle, the shooter 3 is given a vibration in an inclined direction as shown by an arrow A in FIG. 8, and at this time, as shown in FIG. When the object 3 moves diagonally upward, the work W is bounced diagonally upward, and the work W moves along the path by repeating the operation. The passage 2 is provided with a work W so that the work W does not overlap vertically.
Height (thickness) is set to a height smaller than twice the height.

[0004]

This tunnel type transfer device can transfer the work W in order, but the conventional device 1 has a problem in that the transfer speed is limited. That is, in order to increase the transfer speed in the transfer device 1, it is conceivable to apply a strong vibration to the shooter 3 to increase the jumping height of the work W. Since there is a limit in relation to the height, when a strong vibration is applied to the shooter 3, as shown in FIG. 9 (A), the work W moves to the upper surface 2a of the retracted shooter 3.
Will be bounced back,
He could not fly a long distance. Therefore, in the conventional transfer device 1, as shown in FIG.
Is set so as to fly without hitting the upper surface 2a of the passage 2, so that the transfer speed cannot be increased.

More specifically, according to the prior art, when the amplitude exceeds the fastest transfer speed, the work W hits the upper surface 2a of the shooter 3 and the transfer capability is extremely reduced, so that the transfer speed (in other words, the transfer amount per unit time) is reduced. The setting range was narrow. The present invention improves the transfer speed of a work in a transfer device having a tunnel-type passage,
It is an object of the present invention to expand the setting range of the transfer capacity.

[0006]

In order to achieve the above object, the present invention provides a method for manufacturing a vehicle, comprising: a shooter having a tunnel-like passage through which a work passes; an upper shooter forming an upper surface of the passage and a lower shooter forming a lower surface of the passage. And these upper and lower shooters are vibrated in opposite directions so as to move up and down together and move horizontally in the opposite direction along the path. "

[0007]

In this configuration, when the lower shooter moves upward obliquely, the work is jumped obliquely upward, and the work moves in the passage by repetition. In this case, in the present invention, since the upper and lower shooters move in the opposite direction in the horizontal direction while moving up and down together, the lower shooter is in the retreating state and the upper shooter is in the forward state when the work is completely lifted. .

Therefore, when a strong vibration is applied to the upper and lower shooters so that the work is bounced higher than the height of the passage, the work bounced obliquely upward by the lower shooter is pushed forward by hitting the upper shooter in the forward state. Will be in a state where In other words, the work is promoted by the upper shooter to move forward.
The distance over which the work is thrown by one vibration of the upper and lower shooters can be made longer than before.

Therefore, according to the present invention, it is possible to increase the jumping speed of the work by imparting a strong vibration to the shooter, and to increase the distance over which the work is thrown by one vibration of the shooter. The transfer speed of the work can be remarkably improved, and the transfer efficiency of the work can be improved. When a strong vibration is applied to the shooter (increase in amplitude), the speed of the work can be increased accordingly, so that the speed of the work can be set in a wide range from low speed to high speed. There is also an advantage that the setting range of the transfer amount of the work per time can be widened.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 6). 1 is a perspective view of the transfer device 11, FIG. 2 is a side view of the transfer device 11, and FIG.
It is II sectional drawing. The shooter 12 of the transfer device 11 is
Upper shooter 14 that constitutes the upper surface and one inner surface of 13
And a lower shooter 15, which forms the lower surface of the passage 13 and the other inner surface, and the upper and lower shooters 14, 15 overlap each other so as to freely slide in the longitudinal direction.
The lower surfaces of the upper and lower shooters 14 and 15 are arranged in the same plane. The upper and lower shooters 14, 15 are made of a magnetic material such as a steel material.

The upper and lower shooters 14, 15 are supported by a base 18 via a plurality of leaf springs 16, 17, respectively. An electromagnetic coil 19 is mounted between the pair of leaf springs 16, 17 of the base 18. ing. First leaf spring 16 supporting lower shooter 15
Is a posture inclined backward in the traveling direction of the work W,
On the other hand, the second leaf spring 17 supporting the upper shooter 14 is in a posture inclined forward in the traveling direction of the work W.

The electromagnetic coil 19 is arranged such that a magnetic force acts on the upper and lower shooters 14 and 15. Therefore, when the electromagnetic coil 19 is intermittently energized, the upper and lower shooters 14 and 15
It moves horizontally in the opposite direction while moving up and down together,
The lower shooter 15 exercises as shown by arrow A in FIG. 4, and the upper shooter 14 exercises as shown by arrow B in FIG.

The upper and lower shooters 14 and 15 may be made of a magnetic material only at the lower part, and the other parts may be made of a magnetic material. Further, a plate made of a magnetic material may be fixed only to the electromagnetic coil 19. Next, the operation will be described in detail with reference to FIGS. 5A is a graph showing the movement of the upper and lower shooters 14 and 15 in the horizontal direction (x direction in FIG. 4), and FIG.
Is the vertical direction of the upper and lower shooters 14 and 15 (y direction in FIG. 4)
5A and 5B, the upper and lower shooters 14 and 15 horizontally move in opposite directions while integrally moving up and down as shown in FIGS. 5 (A) and 5 (B).

FIG. 5C is a graph showing the relationship between the movement of the work W and time. The work W is repelled by the upward movement of the lower shooter 15. The upper and lower shooters 14, 15 and the workpiece W vibrate and leap at the same cycle t. Therefore, when the work W is completely lifted, the horizontal movement directions of the upper and lower shooters 14 and 15 are switched, and the upper shooter 15 is in the forward movement area.

As shown in FIG. 6, when the amplitude is increased by applying a strong vibration so that the work W can be skipped to a height beyond the passage 13, the work W hits the upper shooter 14. At this stage, As shown by the white arrow C in FIG.
Since the direction of the horizontal motion has changed so that the lower shooter 15 retreats and the upper shooter 14 advances, the work W
Pushed forward (accelerated) by upper shooter 14
State. For this reason, the distance L that the workpiece W travels per one vibration of the upper and lower shooters 14 and 15 increases. Also,
Since the frequency of the upper and lower shooters 14, 15 is also high, the initial velocity applied to the work W is also large. Therefore, the transfer speed of the work W can be improved. Further, the setting range of the transfer capacity can be expanded.

As a means for reciprocating the upper and lower shooters in an oblique direction inclined with respect to the horizontal plane, it is not always necessary to use a leaf spring. However, if a linear spring means such as a leaf spring or a bar spring is used, the structure is simplified. There are advantages.
