Description

[Detailed explanation of the idea] The present invention relates to improvements in bottle washing machines.

Some conventional bottle washer machines are equipped with a pre-washing device at the inlet of the bottle washer that uses recovered water as a jet stream. However, bottle washing using the pre-washing device of the conventional bottle washing machine is a washing method using a water jet for a short time, and the time required for the bottle to enter the first caustic tank in the next washing process is short. The water was not sufficient to wash and soften the stains.
Even if the dirt on the bottles that was not washed away by the water jet is softened by the water, it is carried into the first caustic tank in the next washing process, contaminating the tank, and eventually cleaning the bottles in the bottle washer. There was a tendency to reduce the cleaning effect.

The present invention was proposed with the aim of solving the above-mentioned drawbacks of the conventional bottle washer with a pre-washing device and providing a bottle washer with an excellent cleaning effect. In a bottle washing machine having a built-in conveyor, a bottle feeding conveyor for the bottles before being supplied into the main body of the bottle washing machine is disposed below the water jet type pre-washing device, and the conveyor and the bottle feeding conveyor are connected to each other. are connected by a bottle feeding conveyor, and the bottles on the bottle feeding conveyor are splashed with water falling from the water jet type pre-washing device.

Hereinafter, the present invention will be specifically explained with reference to embodiments shown in FIGS. 1 and 2.

In FIG. 1, reference numeral 1 denotes a pre-wash bottle nozzle 8 of the nozzles 6, 7, 8, and 9 of a well-known water jet type pre-wash bottle disposed inside the bottle washer main body 3.
The downstream side of the bottle feeding conveyor 1 is connected to the upstream side of the bottle feeding conveyor 11, which will be described later, as shown in FIG. 2. 2 is a dirty bottle 4 before being fed to the bottle washing machine
5 is a bottle feeding conveyor whose upstream side is connected to the downstream side of the bottle feeding conveyors 11 and 12 (see Fig. 2).
As shown in the figure, a large number of bottle holders (carrier baskets) are installed to hold the bottles that circulate within the bottle washing machine main body 3 and are sequentially fed into the bottle washing machine main body 3 from the bottle feeding conveyor 4. A bottle supply device, 10 is a partition plate that separates the flow of water jet from the nozzles 6 and 7 side of the water jet type pre-washing device and the nozzle 8 and 9 side, and 13 is a partition plate that separates the washed bottles from the bottle washing machine to the outside. The delivery conveyor is shown (see Figure 2).

An embodiment of the bottle washing machine of the present invention is constructed as described above, and the bottles 2 are fed to the bottle conveyors 11 and 12.
The bottles are fed to the bottle conveyor 4 by the bottle washer body 3, are held in the bottle holder (carrier basket) of the bottle feeder 5 that circulates in the bottle washer body 3, and are held in the bottle holder (carrier basket) of the bottle feeder 5 as the bottle feeder 5 circulates. Move with speed. During this movement, the bottle is normally preliminarily washed inside and outside with recovered water from a pre-washing device in the bottle washing machine main body 3. The main purpose of this is to remove dirt and dirt that are relatively easy to remove from the inside and outside of the supply bottle before the bottle enters the first caustic tank (immersion tank), to prevent the liquid in the tank from becoming contaminated, and to improve the cleaning effect. The main purpose is to make the bottle last longer and to pre-soften the soiled part of the bottle. For this reason, washing the inside and outside of bottles using a water jet type pre-washing device having nozzles 6, 7, 8, and 9 as shown in FIG. 1 has been widely practiced.
As mentioned earlier, with this conventional method, the time required to wash the bottle with the water jet stream is short, and there is not enough time for the water to penetrate into the dirt on the bottle, so it is not possible to sufficiently remove the dirt on the bottle. There was a drawback.

In the present invention, before the bottles 2 are fed into the bottle washing machine main body 3 by the bottle feeding conveyor 4, the bottles 2 are passed through the bottom of the water jet type pre-washing device at a predetermined speed via the bottle feeding conveyor 1. During this time, the inside and outside of the bottle 2 are sufficiently wetted with the jet water flow from the nozzles 8 and 9 of the pre-washing device to sufficiently soften the dirt on the bottle 2, and then the bottle 2 is transferred to the feeding bottle conveyor. 1
1 and 12 and into the bottle washing machine main body 3 by the bottle feeding conveyor 4, and while being held by the bottle holder of the bottle feeding device 5 and moving inside the bottle washing machine main body 3, each nozzle of the pre-washing device Dirt inside and outside the bottle 2 is sufficiently removed by jet water flows from 6, 7 and 8, 9. Therefore, there is no risk of contaminating the liquid in the immersion tank (first caustic tank), and the cleaning effect of the bottle 2 is fully exhibited.

Note that the illustrated bottle feeding conveyor 11 section may be changed to a different layout, and preliminary bottle inspection by hand or machine or other auxiliary machines may be installed in this section.

Furthermore, as shown in Fig. 2, the increase in the layout space due to the bottle feed conveyor 1 inside the bottle washer main body 3 is relatively small, and rather the anchor can be installed closer to the bottle washer, reducing the overall layout space. There is a possibility that it can be reduced.

Since the bottle washing machine of the present invention has the above-described configuration and operation, according to the present invention, before the bottles are fed into the bottle washing machine main body 3 by the bottle feeding conveyor 4,
The dirty bottle 2 is washed in advance using the washing water of the water jet type pre-washing device, and after the dirt is removed in advance or the dirt is softened by absorbing water, the nozzle 6 of the pre-washing device is used. , 7, 8, and 9, dirt on the inside and outside of bottle 2 is completely removed, and there is a risk that dirt from bottle 2 may be brought into the soaking tank for the next washing process. This has a practical effect in that there is no cleaning effect at all, and therefore the cleaning effect of the bottle 2 is fully exhibited.

In addition, as shown in the illustrated example, a partition plate 10 is provided between the front and rear parts of the bottle washer main body 3, and the relatively clean recovered water is used in the nozzles 8 and 9 of the pre-washing device, and the recycled water is recycled. When the recovered water is used in the nozzles 6 and 7, the liquid that was present in the bottle 2 from the beginning and the water that was supplied into the bottle by the bottle feeding conveyor 1 will be
The bottle is discharged from the bottle together with the internal waste water at a position around A of the bottle feeding device 5, and the dirt inside and outside the bottle is washed away by the nozzles 6 and 7. Due to this action, bottle 2
The advantage is that most of the easily removed dirt such as bulky garbage and soil that adheres to the bottle can fall on the front side of the partition plate 10, and can be prevented from falling onto the bottles 2 on the bottle feeding conveyor 1 as much as possible. There is.
