Abstract

PURPOSE:To simplify constitution, and to improve applicability for general purpose by projecting a guide cylinder, a nose thereof is formed in the form of an obliquely cut receiving port, onto a narrow bottom and slidably mounting the guide cylinder vertically in the bottom of a hopper with the narrow bottom in the part feeder for carrying a small-sized electronic part, etc. CONSTITUTION:The hopper 2, the bottom 1 thereof is narrowed, is filled with the parts, and the guide cylinder 4 is vibrated and the parts are vertically replaced periodically. Consequently, the parts are forwarded into a part feed pipe 6 one by one from the obliquely cut receiving port 5. According to said method, the constitution is simplified, an applicable part range is extended, and the parts can be carried smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parts feeder with a simple structure for transporting small electronic parts, etc. Conventionally, parts feeders include so-called linear parts feeders and paper tape transport systems. The former has the disadvantage of high equipment costs, and the latter has the disadvantage that the parts manufacturer must be specified.

This invention aims to eliminate the above-mentioned drawbacks, and its gist is that a drop hole 3 is provided at the lowest part of the bottom surface l of the hopper 2 whose bottom surface i can be narrowed, and a guide tube 4 is provided in the drop hole 3. This is a parts feeder in which the guide tube 4 is slidably fitted on the bottom surface 1 so as to be able to move in and out periodically and is oriented substantially vertically.

The present invention will be explained below based on an embodiment shown in FIGS. 1 to 3. What is shown in the drawing is a hopper 2 whose bottom surface 1 is narrowed in the shape of a funnel, with a drop hole 3 provided at the lowest part of the bottom surface 1, into which a guide tube 4 can be moved in and out periodically on the bottom surface 1. The guide tube 4 is slidably fitted with the guide tube 4 facing substantially vertically, and the tip of the guide tube 4 is beveled to form a receptacle 5.

The guide tube 4 can be periodically moved in and out of the bottom surface 1 by driving the guide tube 4 with an electromagnetic valve, a pulse motor, or the like.

The tip of the guide tube 4 is beveled to form a socket 5. The inner diameter of the guide tube 4 is large enough to allow the parts 7 to pass through one by one.

The lower end of the guide ta4 is connected to the parts transporter 6.

The hopper 2 is filled with small parts 7 such as electronic parts, and when the guide tube 4 is vibrated and moved in and out periodically up and down, the part 7 is tilted and one piece of the part 7 is placed from the tip of the receiver, which forms the opening 5. Each receiver is placed in the container and sent to the parts transport chamber 6.

As described above, in the parts feeder according to the present invention, a drop hole 3 is provided at the lowest part of the bottom surface 1 of the hopper 2 having a narrow bottom surface L, and a guide tube 4 is slidably inserted into and out of the bottom surface 1 into the drop hole 3. It has a simple structure in which the leading end of the guide tube 4 is beveled to form the opening 5. Further, since the tip of the guide tube 4 is beveled to form a receiving opening 5, the parts 7 can be received smoothly.
