Abstract

PROBLEM TO BE SOLVED: To enter articles into an alignment part in a normal form and to separate them one by one without fail, by repeating the mormal and the reverse rotations, and carrying out a specific amount of phase transfer at an alignment transfer part. SOLUTION: Articles thrown in to a bowl 38 are collected to the lower side 19 of a disk 37 which is inclined to the horizontal direction of an alignment transfer part. The disk 37 fixed to the alignment rotating part 6 repeats the normal and the reverse rotations, and rotates in a specific directions while being vibrated. As a result, an article placed on the outer peripheral side of the upper surface of the disk 37 moves upward, and when it moves upward at a certain level, it drops along the upper surface of the disk 37. By repeating such an operation, the articles are arranged regularly on the outer periphery of the disk 37, and housed in an alignment part. The articles coming to the disk upper side 13 of the alignment transfer part are decided whether they are stored by separating one by one or not, and whether they are stored in a specific posture or not.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article feeding apparatus.

[0002]

2. Description of the Related Art A vibration type parts feeder is widely known, but it is an article to be aligned and conveyed (hereinafter referred to as an article).
There is a spiral article movement guide path inside the bowl for throwing in, and by applying vibration, the article moves along the guide path, and the posture correction unit corrects it to a predetermined posture and supplies it to the next step. ing. Further, as a feeding device using a rotating disk, there is a headed bar material separating and feeding device described in Japanese Patent Laid-Open No. 5-58433, which has an inclined rotating disk inside a bowl and has a concave shape on its outer peripheral portion. There is an article aligning section, and the articles are separated one by one on the outer circumference of the rotating disk by the rotation of the motor and supplied to the next step.

[0003]

However, in order to have high versatility, the above-mentioned vibrating parts feeder can be used for various kinds of articles by exchanging bowls, posture correcting parts, and adjusting vibrations. There is a problem that the structure becomes complicated and therefore expensive, and that when the article is changed, it takes adjustment time to replace the bowl and the posture correction section. Further, in the headed bar separation device in the forefront, since the articles are tried to be separated one by one by rotating in one direction of the rotating disk, the articles do not enter the alignment section in a normal shape, and are caught by the articles entering the alignment section. There is a problem that other articles are lifted up to the supply position for the next process. Therefore, the present invention has a high versatility in order to solve the above-mentioned conventional problems, and has a simple structure.
When changing the goods, it takes almost no adjustment time just by exchanging the disk of the feeding section, and the shape of the disk is simple, so it can be produced at low cost. An object of the present invention is to provide an article feeding device that allows articles to enter the aligning section in a normal form by a certain amount of phase movement and to separate them one by one.

[0004]

In the feeding apparatus constructed according to the present invention as described above, when an article is put into the main body, the article is placed at the lower part of the disk which is inclined by 30 degrees with respect to the horizontal plane of the feeding section. Gather to the side. Items that are on the outer peripheral side of the upper surface of the disk of the feeding section rotate on the upper surface of the disk of the feeding section because they rotate in a certain direction while repeating forward and reverse rotational movement and a certain amount of phase movement, that is, vibration. With this, the article moves upward to some extent, and then drops along the upper surface of the disc of the feeding section. By repeating this movement, the articles are regularly arranged and opened on the outer circumference of the disc of the feeding section. It is stored in the alignment section. The articles that come to the upper side of the disc of the feeding section (article supply position) by the rotation of the disc of the feeding section are separated and stored one by one, and aligned by the detection section installed on the upper side of the disc of the feeding section. It is determined whether or not it is stored in the unit, and if it is stored, it is stored in a predetermined posture.
Items stored in the specified posture are OK from the detection unit.
The signal causes the article to be moved by the carrier of the device to be transferred. For an article that is not stored in a predetermined posture, the NG signal from the detection unit causes the air valve to operate, air is jetted, and the article is blown away from the horizontal direction,
It drops along the upper surface of the disc to the lower side of the disc of the feeding unit, which is inclined, and merges with the articles gathered on the lower side of the disc of the feeding unit to be fed again. In addition, when the article is changed, it is necessary to change the size of the hole in the alignment section of the disc of the feeding section. This can be done by loosening the knurled nut that fixes the disc of the feeding section, replacing the disc, and tightening the knurled nut to fix the new disc.

It rotates in a fixed direction while repeating forward and reverse rotational movements and a fixed amount of phase movement, that is, vibration. Therefore, the articles on the outer peripheral side of the upper surface of the disc 37 of the feeding unit 2 move upward with the rotation of the upper surface of the disc 37 of the feeding unit 2, and when they move upward to some extent, the feeding unit 2 moves.
It drops along the upper surface of the disk 37. By repeating this movement, the articles are stored in the aligning section 7 which is regularly arranged and opened on the outer circumference of the disk 37 of the feeding section 2. By the rotation of the disc 37 of the aligning unit 2, the articles that have reached the disc upper side 13 (article supply position 31) of the feeding unit 2 are separated and stored one by one, and installed on the disc upper side 13 of the aligning unit 2. The detected detection unit 5 determines whether or not it is stored in the alignment unit 7 and, if it is stored, whether or not it is stored in a predetermined posture. The article stored in the predetermined posture is moved by the transport device of the apparatus to which the article is to be transferred, in response to the OK signal from the detection unit 5. Items that are not stored in a predetermined posture are detected by the NG signal from the detection unit 5,
The air valve is actuated, air is jetted from the air jet port 18, the article is blown off, and the article falls along the upper surface of the disc 37 to the disc lower side 39 of the feeding unit 2 inclined by 30 degrees from the horizontal direction, The articles gathered on the disk lower side 39 of the feeding section 2 are merged and fed again.

Further, when the article is changed, it is necessary to change the size of the through hole 30 of the disk 37 of the feeding section 2.
This is done by loosening the knurled nut 28 fixing the disc 37 of the feeding section 2 and removing the disc 37,
7 is a positioning pin 1 fixed to the disc mounting plate 26
It can be dealt with only by mounting so as to be positioned at 9, and tightening and fixing the knurled nut 28.
