Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic vibration type horizontal feeder for feeding parts fed from a bowl feeder or the like to an external machine.

A conventional horizontal feeder (picking feeder) has two parallel springs installed on a base, with a parts guide that becomes a track strung almost horizontally across each end of the spring, and this is supported by an electromagnet on the base. Since this is a type in which the parts are moved straight in one direction by excitation, there is a problem in that the vibration of the electromagnet is propagated to the base due to the reaction force of the excitation force.

In addition, in the above-mentioned horizontal feeder, it is possible to arrange a large number of them side by side and arrange these part guides in parallel in a horizontal plane, but a multi-bowl feeder in which a number of independent bowl hoppers are stacked in multiple stages on one feeder is not possible. In addition to this, horizontal feeders must be stacked one on top of the other.This is because the leaf springs of the horizontal feeders stand up vertically, making them taller and stacking each horizontal feeder vertically. It is difficult to stack feeders with narrow vertical spacing, such as with multi-bowl feeders. The present invention has been made in view of the above-mentioned situation, and includes four leaf springs arranged horizontally on a mounting board, and two part guide rails independently attached to one set of leaf springs using these two leaf springs.ゞHorizontally arranged side by side 2
A parts track (parts conveyance path) is formed by attaching an excitation electromagnet between the parts guide rails of the book, and 2
The vibration directions of the book parts guide rails are set in opposite phases to prevent vibration propagation to the mounting board, and one set of horizontal feeders is in a short, flat state, making it possible to maintain a large number of horizontal feeders upright at narrow vertical intervals. It can be attached to and stacked on plates, and we have succeeded in providing a horizontal feeder device that is optimal for multi-bowl feeders.

Next, the horizontal feeder device of the present invention developed for a multi-bowl feeder will be explained with reference to the embodiments shown in the drawings.

9a and 20a face each other with a small gap left, forming one parts track (parts transport path) PT.

M is the assembled frame 1 in the facing space a of the narrow frames 12 and 13
The electromagnet is fixed to the wall surface 12b' of No. 2 with bolts 22, and the suction iron piece 2 facing the guide rail in the longitudinal direction is an electromagnet.

The two parts guide rails 19 and 20, which are independently supported at the tips of the parts guide rails 19 and 20, are excited in the longitudinal direction in opposite phases. The horizontal feeder HF has a very low back height h and is constructed in a flat shape. The illustrated horizontal feeders HF, (-HF7), which are embodiments of the present invention, are constructed as described above and operate as follows.

Since each horizontal feeder HF, (~HF7) is configured in a flat shape with a low back height h, a large number of horizontal feeders can be connected to the front surface of the base plate 3 with narrow vertical spacing.
a can be attached and stacked, thereby forming a multi-stage horizontal feeder SFo with track ends T,'-T7' coming out from each bowl hopper B-B7 of the multi-bowl feeder BF.
The vertical spacing and the tip P of each part track PT, ~PT7
T,' to PT7' are aligned and matched, and parts (not shown) coming from each bowl can be smoothly introduced into the parts tracks PT, to PT7. Each horizontal feeder receives 120Hz (100H
A pair of parts guide rails 19 and 20 are each vibrated in the longitudinal direction with a low frequency of 60 Hz) or 60 Hz (50 days 2) in an opposite phase relationship. Now the parts track (parts guide rail) PT, ~The upper part is the leaf spring 10a~
10d and tilted to the right, it is transferred straight to the left, but the two parts guide rails 19 and 20 propel it alternately every half cycle, so it is about twice as much as when using one parts guide rail. This enables stable parts feeding even on long parts tracks without the irregular vibrations and uneven feeding seen with subordinate linear feeders (horizontal feeders). Furthermore, since the two parts guide rails 19 and 20 are vibrated in opposite phases, the vibration propagation of the electromagnet M to the base plate 3 is canceled out, and this vibration is greatly reduced. 1, this eliminates the possibility of the joint between the multi-bowl feeder BF and the multi-stage horizontal feeder HFo becoming misaligned, making it possible to supply parts smoothly. Furthermore, parts feeding speed and direction adjustment for each horizontal feeder HF are controlled by each tightening piece 6a to 6d and 14a to 14.

This is done by adjusting the rightward tilt angle or changing the leftward tilt angle from a to 10d. In the above embodiment, one parts track PT is formed by two parts guide rails 19, 20, but the present invention is not limited to this, and parts guide grooves 19a, 2 are formed in each part guide rail 19, 20.
0a may be independently recessed to form two parts tracks so that two types of parts can be fed. Since the horizontal feeder of the present invention is as described above, the vibration directions of the two parts guide rails forming one parts track (parts conveyance path) are in opposite phases, and the vibrations are transmitted to the base plate for mounting. In addition to preventing propagation, the plate springs are arranged side by side in a horizontal position so that one set of horizontal feeders has a short, flat shape, and a large number of horizontal feeders are mounted upright with narrow vertical spacing. It can be attached to the front of the multi-stage horizontal feeder and stacked to form a multi-stage horizontal feeder, which can be connected to the end of each track of the multi-bowl feeder with the same vertical gap, providing excellent effects in combination with the multi-bowl feeder, etc. Demonstrate.
