Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing device for a plastic case such as milk.

[0002]

2. Description of the Related Art A plastic case for transporting a milk container or the like is collected when it is used. However, each time it is collected, it is washed at a factory and reused. However, since the case is washed in an upright state, the product may be packed as it is despite foreign substances remaining inside.

In order to solve such a problem, there has been a mechanism in which a plastic case is turned upside down to remove foreign matter by being twisted by a belt conveyor or dropped and dropped by an air cylinder to remove the foreign matter.

[0004]

However, when such a mechanism is adopted, the apparatus becomes complicated and large-scale, and the energy is required for a motor or the like, so that the cost is increased and the adoption is difficult.

The present invention has been made to solve the above-mentioned problems and to provide an inverting device which is inexpensive and can save energy.

[0006]

A rotating shaft 1 is provided at the rear end of the conveyor 2 in the conveying direction, and an arm 3 is fixed to the rotating shaft 1. A tilting plate 4 fixed to a support shaft 5 extending in the forward direction of a stay 6 provided below is fixed, and the upper end of the tilting plate 4 is connected to the conveyor body 2 via a tension spring 7. At the same time, a stopper 4a is formed at the lower end of the tilting plate 4, and a disturbing projection is protruded from the tip of the stopper 4a.

[0007]

[Operation] Since the present invention has the above configuration, it has the following operation. The plastic case C transported from the roller conveyor 2 in the upright state is
It falls along the arm 3 and the tilting plate 4, stops at the stopper 4a in the upright state of the tilting plate 4, and the foreign matter in the case C is moved downward. At this time, the support shaft 5 acts as a lever by the shock at the time of dropping, and the engagement plate 4 below the support shaft 5 bends.
Becomes sloppy forward. And case C
Is inverted so that the upper front edge of the stopper 4a stumbles on a baffle provided at the tip of the stopper 4a, and foreign matter inside the case C is discharged, and at the same time, the case C is transferred to the belt conveyor 8 in an inverted state. Therefore, the foreign matter in the case C is completely washed and washed.

Since the upper end of the engaging plate 4 is constantly pulled by the tension spring 7, the shock when the case C falls is reduced, so that the case C is prevented from being damaged.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

Reference numeral 1 denotes a rotary shaft, which is rotatably mounted at the rear end of the roller conveyor 2 in the transport direction.

Reference numeral 3 denotes a substantially V-shaped arm, which is fixed to the rotary shaft 1.

Reference numeral 4 denotes a tilting plate having a stopper 4a at the lower end, which is fixed to the tip of the arm 3.

Reference numeral 5 denotes a support shaft which is fixed substantially above the back surface of the tilting plate 4 and is provided in the forward direction of a stay 6 provided below the roller conveyor 2, and a bearing fixed to the stay 6. 9 is provided.

Reference numeral 7 denotes a tension spring, which is provided between the upper end of the tilt plate 4 and the roller conveyor 2, and constantly pulls the tilt plate 4.

[0015]

[Effects of the Invention] The present invention has the above-described structure, and therefore has the following effects.

By simply placing the case C on the conveyor 2 in an upright state, the tilting plate 4 can be operated and inverted by the weight of the case C when dropped from the conveyor 2, so that the work of removing foreign substances by hand can be performed. Work efficiency is good because it is not required.

Since it is a device for inverting by using a shock when the case C falls, it is very economical because it does not require energy such as a power supply.

The tilting plate 4 bends due to a shock at the time of falling, but returns immediately to its original position, so that the standing case C is inverted, so that the work speed can be increased.

The upper end portion of the engagement plate 4 is provided with a tension spring 7 at all times.
As a result, the shock when the case C falls can be relieved, and the case C can be prevented from being damaged.
