Description

[Detailed Description of the Invention] [Summary] The present invention separates and intermittently supplies parts arranged in a line from a parts feeder to a chute into supply ports branched into multiple locations, and at the same time This invention relates to a distributing and reversing device for parts that are reversed in direction.

[Prior art j] In order to divide parts that were conventionally supplied from a parts feeder in a line and continuously supplied to one chute to each branch chute having a plurality of supply ports, the tail end of the main shoe 1 to There are those that simply have a branch chute connected to the branch, and those that have a distribution member installed at this branch point. A branch chute equipped with a distribution member has the advantage of ensuring that components are supplied to the supply ports of each chute in an orderly manner, but it is not possible to simultaneously supply components to the supply ports of each branch, so parts cannot be distributed at high speed. is not possible, and the structure of this distribution member is also complicated.

Furthermore, in the case where each supply port of the branch chute is provided with a component reversing member, it is desirable that the components are simultaneously supplied from each supply port to the reversing member.

This is because it is desired that each component supplied to the reversing member be reversed all at once by one actuator. Since the intermittent and simultaneous supply of components to each branch chute and the component reversal operation are performed by separate actuators, the synchronization of both members is poor, making high-speed distribution and reversal difficult. Therefore, in the above-mentioned conventional component distributing and reversing device, there are problems in that the reversing member cannot be distributed all at once to each supply port intermittently, and the synchronization between the reversing member and the component distributing member is poor. .

``Object of the present invention'' The present invention was made in view of the problems of the conventional parts distribution and reversal device described in 1.The first purpose is to arrange parts in a line from a parts feeder, etc. - C. It is an object of the present invention to provide a component distribution/reversal device equipped with a new component distribution member that can separate and intermittently simultaneously supply continuously supplied components to supply ports of a plurality of branch chutes.

The second purpose is to connect a reversing shaft with a component receiving port facing each supply port of the branch chute to an actuator of the component distribution member, and when the actuator operates, the component distribution member transfers components to the branch chute I. - To provide a component distributing and reversing device equipped with a reversing member that synchronously rotates a reversing shaft so that the components at the component receiving port are oriented in the unloading direction after being separated and intermittently supplied to each of the supply ports. It is something.

Therefore, when using the parts distributing and inverting device of the present invention that achieves the above object, it has a distribution function that separates parts to each supply port and supplies them all at once intermittently, and a function of distributing the parts distributed to each parts receiving port. The function of reversing in the unloading direction is organically combined by one actuator, and we succeeded in processing the distribution and reversal of parts at high speed as a single device.

3a passes through the guide groove 21b121b of the reversing shaft 21, it catches the parts p, +, p2', and supplies the parts p1', p, I to a press-fitting position of a press-fitting machine or the like prepared at the forward end position. After supplying the parts, the transport rods 22 and 23 retreat to the standby position again, and this is detected by the limit switch LS□, and this detection signal provides a retreat command to the drive rod 15, which is stopped at the forward end, and causes the cylinder C to move back. The piston rod 7 is moved back. Now, the drive rod 15 begins to move to the retreat end where it is stopped by the stop bolt 17, and the parts receiving ports A, ', B' in the horizontal position are moved to the supply port A,
At the same time as returning to the vertical position facing B, the driving rod 16 presses the rear end collar 14a of the operating rod 14 just before the retreating end,
The support plate 8 is moved back toward the side opposite to the chute against the force of the spring 13 (6). By this operation of cylinder C, two parts P1 and P2 in chute S are branched from part P again, and each supply port A,
The cycle of simultaneously supplying to B is repeated.

As described above, the parts distribution member 10 provided in the chute S can separate the necessary number of parts from other parts and intermittently supply them all at once by moving the pins 2 to 4 and the bottom plate 5 forward and backward using the cylinder.
