Go forward and put the can
Position, and after the transfer, the lever is in the vertical position,
The reciprocating cylinder 2 moves backward and returns to the original position. In this continuous operation, the can is transferred from the B position to the H position. Extrusion of the cylindrical can to the position B is performed by setting the section corresponding to several cylindrical cans immediately after the position B of the roller conveyor 1 to a power conveyor by a drive motor, and when the tact transfer lever 3 returns to the original position. Since the stopper is set so as to be released by the cylinder, the cylindrical cans on the power conveyor immediately after the position B are extruded one by one from the position B. Further, since the tact transfer lever 3 is composed of seven consecutive U-shaped levers, the continuous operation of the lever allows
The cylindrical can Y is a transfer mechanism A that is timely transferred from the position B to the position H at a constant rhythm. In some cases, it is possible to increase the lever when the stroke increases and to reduce the lever when the stroke decreases, so that the operation can be performed in response to the stroke.

The cylindrical can Y pushed out to the position B is transferred to the position C by the tact transfer lever 3, and at the position C, there is a mechanism C for setting the set position of the cylindrical can Y.

The required time for one lot can be set in advance and implemented. The work can be freely moved and installed at a desired place, and can be carried out in connection with a filling device.

[0026]

Since the present invention is configured as described above, it has the following effects.

By the transfer mechanism A, the cylindrical can Y filled with the filler can be timely transferred on the roller conveyor at a constant rhythm.

If the inner lid N is provided at several places by the inner lid loading / supplying mechanism K and Geneva gears are set according to the number of places, the inner lid N can be supplied in one lot.

By the inner lid pickup mechanism M, even if the inner lid N is a thin film material molded product, the pickup can be easily supplied one by one.

By the inner lid transport mechanism I, the inner lid N picked up by the pickup mechanism M can be easily transported to the position D, and the inner lid N can be surely placed in the opening of the cylindrical can Y at the position D. Is possible.

The inner lid close air bleeding mechanism E allows the inner lid N to be in close contact with the filling of the cylindrical can Y, and allows the air between the inner lid N and the filling to be completely removed.

By the inner lid fitting and mounting mechanism F, the upper peripheral folded portion of the inner lid N can be fitted and mounted on the periphery of the opening of the cylindrical can, and the central protrusion of the filling can be formed flat on the entire surface. It is possible.

[0033] The outer lid stacking supply mechanism L _1, outer lid S one by one are possible or reliably attracted feed enables a large number of continuously supplied, further, adoption of the outer lid stacking supply mechanism L ₂ Thereby, a larger number of outer lids S can be supplied.

Further, when the apparatus is connected to a filling device for filling and operates as an integral unit, the filling of the filling into the cylindrical can and the mounting of the inner lid and the outer lid can be performed fully automatically.

Among the various mechanisms of the present invention, the longest processing time is about 7 seconds. Therefore, when the tact transfer lever 3 is six, the inner lid and the outer lid in the apparatus of the present invention need not be mounted. Although it takes 42 seconds in 6 strokes, the inner cover and the outer cover are mounted every 7 seconds because of the simultaneous movement. If the required time for one tact operation is reduced to about 5 seconds, it takes about 30 seconds for 6 strokes, but since it is a simultaneous movement, the mounting of the inner lid and the outer lid progresses every 5 seconds. .
