2. Description of the Related Art Conventionally, in automatic bead molding machines, 50
There has been proposed a bead supply device that reliably feeds separated and aligned bare beads to the next step one by one without bringing them into close contact with each other. As a pitch feed mechanism of such a bead supply device, for example, as shown in FIGS. 6 and 7, two fixed beams 2
A plurality of bead cores W separated and aligned above and suspended and held are moved by a moving arm 3 disposed between fixed beams 2.
Is rotated in the front-rear direction via the eccentric drive mechanism 4 to advance the fixed beam 2 to the leading end of the fixed beam 2 for every one pitch, so that the suction extraction means 5 can perform horizontal extraction.

[0003]

[Problems to be Solved by the Invention] However, the above-mentioned suspension-type pitch feed mechanism is good for always feeding bead cores of a fixed size (diameter), but it is good for feeding bead cores of different sizes. Therefore, there is a problem that it is difficult to reliably hold the bead core and feed the pitch because the top dead center position for holding the pitch changes.

As another device, for example, Japanese Patent Publication No. 4-29538 (annular member take-out and supply device) has been proposed, but a plurality of bead cores suspended and held by being separated and aligned with a bar at a constant pitch. In order to take out the bead removal device with filler, move the bead removal device with filler to the tip side of the bar and take it out while holding by suction, so that the bead removal device with filler is sequentially moved along the traveling platform according to the change in the suspension position of the bead core. Therefore, there is a problem that much trouble and time are required for control and trouble for changing the operation stroke of the bead removing device with filler.

The present invention has been devised in view of such a conventional problem, and it is possible to reliably hold a bead in correspondence with various sizes of bead cores and to prevent the bead cores from sticking together. It is an object of the present invention to provide a bead supply device capable of reliably performing pitch feed to the next step.

[0006]

According to the present invention, in order to achieve the above object, a base end of a moving arm disposed between fixed beams is connected to an eccentric drive mechanism via a drive lever, and the moving arm is provided. At the leading end of the arm is provided with an elevating means for elevating the moving arm in conjunction with the eccentric drive mechanism.

[0007]

The present invention is configured as described above, and the moving arm disposed between the fixed beams is turned in the front-rear direction by an eccentric drive mechanism connected via a drive lever, thereby providing a bead core. The pitch can be reliably fed without bringing the comrades into close contact with each other, and the tip side of the moving arm is moved up and down via the elevating means, so that the beads can be reliably held in correspondence with various sizes of bead cores. You can do it.

The upper ends of the lifting cylinders 17a and 17b and the extending and retracting ends of the moving arm 3 are
A proximity switch SW is attached to the fixed beam 2, and the proximity switch SW is configured to be connected to the one-rotation control motor 9 to control the rotation drive of the one-rotation control motor 9. In order to prevent the bead cores W from coming into contact with each other due to the stop shock after the support column 1 is turned, a rod 20 is provided on the side surface of the support column 1 for preventing the bead cores W from being pressed lightly by the cylinder. is there.

Next, the operation of the pitch feed mechanism of the bead supply device will be described. When a plurality of bead cores W are separated and aligned on the fixed beam 2 and are suspended and held, the bead cores W are advanced to the take-out end side of the fixed beam 2 at a constant pitch.
When the leading end side of the moving arm 3 is lifted through to move the bead core W suspended on the fixed beam 2 to the moving arm 3, and when the proximity switch SW detects that the bead core W has been transferred, Lifting means 7
