Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to parts supply. Parts were supplied by placing the parts on a disc or belt and transporting them, or by moving stairs such as an escalator from inside the hopper. There is also a method of sucking and lifting the parts to be supplied using an electromagnet or a vacuum vat and supplying them to a predetermined position. In order to supply thin parts to be supplied, a feeder that uses vibration is difficult to transmit vibrations to the parts to be supplied, and the transfer speed is slow, making it impractical. If the parts are transported on a conveyor or disc, the thin parts to be supplied may become stuck in the gap between the movable part of the disc or conveyor and the fixed part that fixes it, making it impossible to supply them, or two parts may overlap. It was difficult to make each sheet one by one. The disadvantage of the hoisting method was that the electric wires that supplied power to the electromagnets and the vacuum piping had to be moved at the same time. Although the present invention is a method of moving the supplied parts by lifting them, a screen that moves in front of the suction power source is provided without moving the suction power source, that is, an electromagnet or a vacuum vat, etc., to move the supplied parts. By adsorbing the part onto the screen, moving it to a position where it is not affected by the adsorption power, releasing the adsorption, and supplying the supplied part to the predetermined position, the electric wire for lifting can be moved as before. At the same time, it eliminates the drawbacks of moving pipes and pipes, and at the same time, it makes it easier to supply thin parts one by one at regular intervals by providing parts that can be sucked at regular intervals on the screen and sucking the supplied parts one by one. The purpose is to

FIG. 1 is an explanatory view for explaining the principle of the present invention using an embodiment using vacuum suction, and is a view seen from below. The suction tool 1 provided above is connected to a suction power source (not shown), such as a vacuum pump, and has a suction surface 3 below. Even if the suction surface 3 is a curved surface that is convex with respect to the screen, this does not change the spirit of the present invention. In the embodiment shown in FIG. 1, the suction tool 1 is formed as a hollow body having an opening as a suction surface 3 at the bottom.

The suction surface 3 is driven by a drive source (not shown) below the suction surface 3.
A screen 2 is provided which slides on the 1
have one or more adsorption sites.

4.5.6.7.9 is the object to be supplied, and 8 indicates the position where the object to be supplied falls. The screen 2 is made of a material that prevents the supplied object from being sucked by the suction tool, and the suction portion is a part of the screen 2 through which the supplied object can be suctioned by the suction tool through the screen 2.

In the case of vacuum suction, the screen 2 is made of a non-breathable material, and suction parts are provided in the screen and a ventilation window of a shape and size suitable for the object to be supplied. The adsorption site is formed by a single 0 vent or multiple small holes. FIG. 2 is an example of a screen. FIG. 2(a) shows an embodiment in which the screen 2 is formed of a net and has convex portions 11 provided at appropriate intervals, and the suction portion 10 is formed by the portion of the net surrounded by the convex portions 11'c. FIG. 2(b) shows an example in which the screen 2 has an adsorption portion shaped like the object to be supplied. When the shape of the suction part 10 is required to be cross-shaped, it is implemented by making a cross-shaped hole and providing a net 13 to prevent the object to be sucked from being sucked. Instead of this mesh 13, the small holes 12 on the right side of the figure can be arranged in a cross shape to form the supply site 0.

The operation will be explained with reference to FIG. A supplied object 4 is placed at position 4. The adsorbent 1 containing water is evacuated by an adsorption power source (not shown). The screen 2, which is wider than the opening of the suction surface 3, is moved in the direction of the arrow by a drive source (not shown). The screen is bell! It does not change the gist of the present invention even if the ring is endless in the shape of a ring.

Further, even if the screen 2 is made to perform a swinging motion using a cylinder or the like, the gist of the present invention will not be changed.

The screen 2 is brought into close contact with the opening 3 of the suction tool 1 and is moved in the direction of the arrow. Many adsorption sites IO provided on screen 2
When the object 4 moves upward due to the movement of the screen 2, air flows into the suction tool 1 through the suction part 10, sucking the object 4 in one direction, and the object 5 It is adsorbed at the position of . The sucked supplied object moves while maintaining the state of 5.6 while being sucked by the lower surface of the suction surface 3 of the suction tool 1 by the screen 2, and reaches the falling position 8.

The object to be supplied that has reached the falling position 8 is no longer subjected to the suction action, so it falls to a fixed position and becomes the object to be supplied 9.

After being supplied to the position of the supplied object 4 or 5, when the supplied object is further located at 4, the already adsorbed supplied object 5
Since the object 4 is not sucked up by blocking the air flow, two objects to be fed can be fed one by one without being attracted at the same time. Also, the adsorption site 10
By providing them at appropriate intervals, the objects to be supplied can be supplied at regular intervals. If the size of the suction part 10 is large and two objects to be supplied are attracted to one suction part, it is inevitable to drop the two overlapped objects below the position 6 using a scraping tool such as a plan. This does not change the spirit of the invention. In addition, when the feeding distance is long, the length of the suction surface 3 becomes long, so the suction tool 1 is not formed with a single blank, but with multiple blanks, so that when the object to be fed falls off during transfer. It does not change the spirit of the present invention to reduce the influence of. In addition, the width of the suction surface 3 above the position 5 where the object to be supplied is sucked is increased to facilitate suction, and the width of the suction surface 3 corresponding to the position 6.7 is decreased to meet the needs for holding the object. It does not change the spirit of the present invention to reduce the number 11 of the suction surface 3 sequentially in the length direction (2) of the suction surface 3 so that the suction force can be maintained.

FIG. 3 shows an embodiment in which the suction tool 1 is divided into three parts at right angles in the vertical direction (direction in which the screen moves). In this embodiment, the suction surface 2 is also divided into three parts at right angles to the direction of movement of the screen 2, and the suction device 1 is composed of night snacks 21, 22, and 23; is the suction surface 25,
The night snack 23 will have an adsorption surface 26. screen 2
The suction site 10 above is formed by a cross-shaped window or a group of small holes arranged to form a cross. Night snack 22
When an adsorption power source is connected to the suction power source and a pressurized air source is connected to the suction portions 21 and 23, the small holes 32 in the suction portion of the screen 2, which are arranged in the length direction of the screen, are sucked in, and the holes 32 arranged in the width direction are arranged in the width direction. Air is blown out from the hole 31 on the outside of the hole.

When a rectangular object to be fed is transferred using this device, if the object to be fed 29 is attracted to the screen 2 in the length direction, it will be stably transferred, or if it is attracted like the object to be fed 30, it will be transferred outward. The object to be supplied 30 is
Since the adsorption of the screen becomes unstable and it falls, the object to be fed is fed with its length aligned in the direction of movement of the screen.

In this device, if the sky fish 21 and the water fish 23 are connected to an adsorption power source and the pressurized air is discharged from the midnight snack 22, a rectangular object to be supplied with the longitudinal direction perpendicular to the direction of movement of the screen can be We can supply them in one set.

In the embodiment shown in FIG. 3, the shape of the suction portion, the number and arrangement of the small holes are adapted to the object to be supplied, but it does not change the spirit of the present invention to set them to an appropriate number. Further, the same effect can be obtained by simply releasing the air to the atmosphere without expelling it, so the use of pressurized air is optional.

According to the present invention, the stacked objects to be supplied can be sent one by one at regular intervals (by minimizing the area of the suction part, the amount of air used is reduced and the consumption of labor keys is reduced). It became very possible.

The present invention, which makes it possible to take out and supply stacked objects one by one from the top, greatly contributes to automation.
