JPS591644B2 - Parts feeder fixed height adjustment device using adjustment ring - Google Patents

Description

[Detailed Description of the Invention] The present invention provides a parts feeder in which the legs of a fixed part are fitted into the inner periphery of a fixing ring, and an adjustment ring is screwed into a groove provided above the legs, and the adjustment ring is rotated. By operating
The present invention relates to a device for adjusting the height of a fixed part.

It is well known that conventionally, in this type of parts feeder, the movable part and the fixed part are supported in conjunction at multiple locations by overlapping leaf springs, and vibrations are transmitted to the bowl via these leaf springs. When assembling the main body that houses the drive source, that is, the fixed part, the above-mentioned leaf spring is changed in order to find its resonance point.

However, in this case, variations may occur in the height of the fixed part, or the device for vibration isolating the fixed part may become deflected over time.
When setting the product to an automatic machine for the next process due to changes or tolerances in the level of the installation surface, spacers, etc. are generally used, but this only requires time and effort and requires fine adjustment. It was quite difficult to do so, and the task of matching the above-mentioned levels was extremely difficult.

In order to solve this problem, as shown in FIGS. 1 and 2, the fixing ring 8 and the fixing part 1 are provided at a plurality of locations, for example a, b or a/.

Adjust to b', c, etc. 15, 15' or 1te', 15
1"15"" is provided, and by rotating it evenly, the fixed part 1 is raised and lowered, and its height is adjusted.
When using such a method, it is possible to make fine adjustments in a relatively short time compared to conventional methods. Although it is said that this can be resolved depending on the skill level of the operator, an imbalance in the tightness of the adjustment part is likely to occur, and even after adjustment,
There were drawbacks such as the tendency for the adjustment of the fixed part to be strained at certain points.

In view of the above, the present invention has been developed by screwing a single adjustment ring into the groove provided on the leg of the fixed part, and rotating the adjustment ring.
It is an object of the present invention to provide an adjustment device using a configuration ring that allows the height of a fixed part to be slid simultaneously over the entire part, quickly and accurately, and which can be operated extremely easily without requiring special skill. The present invention will be described below with reference to an illustrated embodiment.

The present invention is completely the same as the adjustment screw shown in Fig. 1.2 in terms of other structural members except for the adjustment part, and some parts overlap because the same reference numerals are used, but in Figs. 3 and 4. , 1 is a fixed part which cooperates and supports the movable part 2 via plate springs 11 stacked diagonally at a plurality of places, and further above the fixed part is a bowl 3 as shown by the dotted line integrally with the movable part 2. It is placed.

4 is a fixed core, and 5 is a movable core.

A coil 6 is wound around the fixed core 4, and a lead wire 7 is pulled out laterally from a hole drilled in the fixed part 1.

Reference numeral 8 designates a fixing ring, which absorbs vibrations by arranging elastic bodies, such as vibration-proof rubber 9 as in this embodiment, at multiple locations, and has a fairly thick inner diameter in its center. The leg portions 1' of the fixing portion 1 that slide vertically on the inner circumferential surface of the fixing portion 8 are fitted.

-10 is an adjustment ring for adjusting the height of the fixing part 1. The inner peripheral surface is threaded, and this thread is screwed into the thread provided at the upper part of the leg part 1'. By rotating the fixed part 1, the fixed part 1 can be slid up and down, and its height can be finely adjusted.

Furthermore, the outer circumferential surface has anti-slip knurling for easy operation with fingertips.

Reference numeral 11 designates the above-mentioned leaf springs, which are stacked on the flat washers 12 at a plurality of locations and tightened with bolts 13 to support the movable part 2 side in conjunction with the fixed part 1 side.

After the level is matched and the adjustment is completed, the fixing part 1 and the fixing ring 8 are fixed with a lock screw 14 provided on the fixing ring 8 side to prevent the plate spring 11 from loosening due to vibration and causing a change in the level. Complete the adjustment work.

According to the present invention as described above, when adjustment holes are provided at multiple locations as shown in FIGS. 1 and 2, not only is it difficult to obtain a uniform degree of adjustment, but the more adjustment locations there are, the longer the time Although it is said that fine adjustment can be done in a relatively short time compared to the conventional method using spacers, it still has some drawbacks that require a certain level of skill. As in the invention, by sliding the legs of the fixing part on the inner circumferential surface and rotating the adjustment ring that is screwed onto the upper part of the legs, fine adjustment is possible without requiring any special skill. Even the adjustments can be made extremely easily, and the height of the fixing portion can be adjusted easily, quickly, and accurately, which is a remarkable effect.
