BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle feeding device for pushing a bottle into a holder of a bottle washing machine or the like.

[0002]

2. Description of the Related Art A conventional bottle feeding device lifts an arc-shaped bottle guide extending upward from the vicinity of the downstream end of a bottle feeding conveyor and a bottle conveyed by the bottle feeding conveyor to move on the bottle guide. It has a rotary pickup arm and a pusher that pushes the bottom of the bottle that has been moved to just before the holder by the pickup arm and inserts it into the holder. This pusher is equipped with detection means that detects when an overload condition occurs due to a bottle or a bottle remaining in the holder, and stops the machine when it is overloaded. ing.

[0003]

Since the bottle feeding device stops just before the pressing of the bottle is completed, it is difficult to remove the bitten bottle.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a bottle feeding device capable of easily removing a broken bottle or the like.

[0005]

A bottle feeding apparatus according to the present invention is arranged between a conveyor for carrying bottles and a bottle processing apparatus for processing bottles, and presses bottles carried by the conveyor. A transfer means for transferring, a bottle guide for guiding the bottle to be transferred, and a pushing means for pushing the bottle transported on the bottle guide into the holder, the pushing means, a swing lever, It consists of a driven lever, a connecting rod that connects both levers, and a pusher that is supported by the same shaft as the driven lever and that swings integrally.The cylinder is installed in the connecting rod and the pusher is not overloaded. It can be expanded and contracted when added.

[0006]

In the bottle feeding device according to the present invention, when the pusher is overloaded due to the residual bottle in the holder or the bottle being broken, the load is released because the connecting rod incorporating the cylinder expands and contracts. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments.
FIG. 1 shows a bottle feeding device according to an embodiment of the present invention, which is provided adjacent to a downstream end of a bottle feeding conveyer 4 that continuously conveys a large number of bottles 2 arranged in a plurality of rows.

This bottle feeding device comprises a bottle guide 6 which extends upward in a substantially arc shape from the vicinity of the downstream end of the bottle feeding conveyor 2 and becomes horizontal, a pickup arm 10 which rotates about a horizontal shaft 8, and a bolt guide. 6 is provided with a pushing means 12 for pushing the bottle 2 into a holder (not shown) of a bottle washing machine 11 (not shown) that has moved to the front of the bottle 6.

Two pickup arms 10 are provided at symmetrical positions with respect to the horizontal axis 8, and a notch 10 engaging with the bottom surface of the bottle 2 is provided on the front side which rotates in the clockwise direction.
a is formed. The pick-up arms 10 are arranged in the same number as the number of rows of the bottles 2 conveyed by the bottle conveyor 4, and the number of rows of bottles is simultaneously lifted on the bottle guide 6. In addition, washing machine 1
One holder is also provided in the same number of rows.

The pushing means 12 includes a swing lever 16 that swings around a horizontal fulcrum shaft 14 slightly above the bottle conveyor 4, and a fulcrum shaft 18 disposed above the downstream end 6a of the bottle guide 6. A driven lever 20 that swings around a center and a swing lever 16 that faces the front (right side in FIG. 1) side of the fulcrum shaft 14.
Connecting rod 22 connecting between the swing end of the driven lever 20 and the swing end of the driven lever 20 facing the rear side of the fulcrum shaft 18, and the driven lever 2 attached to the fulcrum shaft 18 of the driven lever 20.
0 and a pusher 24 that swings integrally.

On the horizontal axis 8 of the pickup arm 10,
A drive cam 26 for swinging the swing lever 16 is attached. The drive cam 26 is provided with a groove cam 26a as shown in FIG. 2, and the cam follower 28 of the rocking lever 16 is engaged with the groove cam 26a, and rocks as the drive cam 26 rotates. The lever 16 swings. The swing of the swing lever 16 is transmitted to the driven lever 20 via the connecting rod 22, and the driven lever 20 and the pusher 2
4 and rock.

An air cylinder is incorporated in the connecting rod 22, and can be expanded and contracted by supplying and discharging air through a solenoid valve (not shown). During normal operation, the cylinder is kept in the most compressed state, and a sensor that can detect only when the piston in the cylinder is at that position is provided.

Next, the operation of the bottle feeder will be described. The bottle 2 conveyed by the bottle feeding conveyor 4 reaches the downstream end of the conveyor 4 and falls down on the arc-shaped portion of the bottle guide 6. The bottom surface of the bottle 2 is pushed up by the pick-up arm 10 which has rotated clockwise from below, and the bottle 2 is guided to the side by the bottle guide 6 in an overturned state and is transferred upward to the horizontal portion at the downstream end of the bottle guide 6. Be stopped. The pusher 24 is swung at the same timing as the bottle 2 reaches this position, and the bottle 2 is inserted into the front holder. During such normal operation, the air cylinder of the connecting rod 22 is kept in the most compressed state. Further, the air cylinder 22 is supplied with a minimum air pressure necessary for pushing the bottle 2 into the holder through a solenoid valve.

When the bottle 2 cannot be inserted into the holder due to a broken bottle or a residual bottle in the holder, and the pusher 24 is overloaded, only the minimum necessary air pressure is supplied to the cylinder. Therefore, the cylinder is extended, and the pusher 24 releases the force pressing the bottle 2. Further, the sensor detects that the cylinder has been stretched, the signal is used to switch the solenoid valve to the side that stretches the cylinder, and the pusher 24 is automatically released from the bottle pushing position. In this way, since the pusher 24 is automatically released at the time of overload, it is possible to easily remove the broken bottle and the like without retracting the pusher 24 by reversing the entire device.

The connecting relationship between the levers 16 and 20 and the connecting rod 22 is not limited to that shown in the drawing, and a structure in which a driven lever is operated via a connecting rod by a crank lever is also possible. Other combinations are possible, in which case the expansion and contraction of the cylinder can be used in reverse. Further, it goes without saying that the shape of the groove cam 26a and the shape of each of the other parts are not limited to those shown in the drawings.

[0016]

As described above, according to the present invention, when the pusher is overloaded due to a bottle or a bottle remaining in the holder, the cylinder of the connecting rod expands and contracts. The overload condition can be eliminated.
