Abstract

PURPOSE:To precisely position the frontmost part at a take-out port and prevent it from springing out through the take-out port, by forming a small hole in the bottom face of the take-up port at the forward end of a conveying passage in a feeder for conveying a part by vibration and mounting an adsorbing means in the small hole. CONSTITUTION:With a feeder 1 vibrated by a vibrating device, a small part (b) is conveyed by vibration. A cover 8 is attached to a conveying passage, and the forward end thereof forms a take-put port 6 through which a frontmost part (a) is taken out by a vacuum adsorbing head 5. In this constitution, a small hole 2, smaller than the small part (b), is bored in the bottom face 3 at the forward end of the feeder 1. A hose 9 coupled to a compressor is connected to the small hole 2 to form a means 4 for adsorbing the front most part (a) to the bottom face 3 at the forward end through suction of it through the hole 2. This prevents the frontmost part (a) from springing out through the take-out port 6 following vibration of the feeder 1, and also allows to precisely position the frontmost part (a) through bringing it into contact with a stopper 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for vibratingly conveying small parts such as chip parts, and more specifically, a technique for preventing the leading thing to be taken out from swinging out at the end of a vibrating conveyance path. Regarding.

Conventionally, when transporting small parts such as chip parts by vibration,
As shown in FIGS. 1 and 2, there is a problem in that at the end of the vibrating conveyance path, the leading object to be taken out is photographed and jumps out of the take-out port (6). (7) in the diagram
is a base, which holds the feeder (1) so that it can freely vibrate.

The present invention was made in view of such problems,
The purpose is to provide a vibratory conveying device that can prevent the first item to be taken out from swinging out, improve positioning accuracy, and ensure stable supply of light parts.

That is, in the present invention, a hole (2) smaller than the part to be transferred is provided on the bottom surface of the top part of a feeder (1) that continuously transfers parts by vibration, and the top part (a) is inserted through this hole (2). A suction means (4) is provided to suction the leading part (a) to the bottom surface (3) of the feeder (1), and the suction force of this suction means (4) is applied to a vacuum suction head (5) for taking out the leading part. This relates to a vibration conveying device characterized by having a suction force that is weaker than the suction force of They were able to provide supplies.

Examples of the present invention will be described below in detail based on eight aspects.

- (1) is a feeder, in which vibration is applied by a vibration device (not shown) so that small parts (b)... stored in a hopper can be photographed and transferred along a conveyance path. . A cover (8) is installed on the conveyance path.
This is to prevent small parts being vibrated from popping out.
There is no cover (8) at the top of the feeder (1), and there is a take-out port (6), which is curved so that the transferred top part (a) can be taken out upward. There is a hole (
2) is on the A line. The leading part (a) is sucked through this hole (2) and the leading part (a) is transferred to the bottom surface (3) of the feeder (1).
) [@A suction means (4) is provided for adhesion.

Adsorption means (4) C hole (2) Hose connected to the circumference (9)
By suctioning the air inside with a suction device (not shown) such as a cosipressor, the leading part (a) is moved through the feeder (
1), so that the leading part (a) does not spring out due to vibration, and the leading part (a) can be positioned by coming into contact with the stopper αQ provided at the leading part, This allows for a stable supply of small parts. A vacuum suction head (5) is provided above the leading part (a) so as to be movable up and down, so that the leading part (a) can be sucked and transferred to the next process. In other words, the adsorption means (4
) is the vacuum suction head (5) for removing the first part.
The suction power is weaker than that of

In summary, the present invention provides a suction means for suctioning the leading part from the hole and adsorbing the leading part to the bottom of the feeder,
Since the suction force of this suction means is weaker than the suction force of the vacuum suction head for taking out the leading part, the leading part can be taken out by the vacuum suction head, so the suction means can be used to take out the leading part. Since the parts were attracted to the bottom of the feeder, it was possible to prevent the leading part from sliding out, ensuring reliable positioning, and as a result, it was possible to stably supply small parts.

Claims (1)

[Claims] (1) Suction means that has a hole smaller than the part to be transferred on the bottom of the top of the feeder that continuously transfers parts by vibration, and sucks the top part through this hole to attract the top part to the bottom of the feeder. A vibration conveying device characterized in that the suction force of the suction means is weaker than the suction force of a vacuum suction head for taking out the leading component.
