Next, the washing and rinsing process of the above-mentioned continuous washing machine will be explained.

First, add detergent and first pre-wash water to the first tank of cylinder 1, or auxiliary water if water is insufficient, add second pre-wash water and detergent to the third tank, detergent to the fifth tank, and add auxiliary water to the first tank of cylinder 1. Bleach in tank 7, main washing water in tank 9, bleach in tank 11, rinse water in tank 13, glue, neutralizer, etc. in tank 14. While feeding, the cylinder 1 (including the partition plate 2 and the hollow shaft 3) is rotated forward and backward by a predetermined angle to swing. Next, after the cylinder 1 has been oscillated for a predetermined period of time, the cylinder 1 is rotated once (360°). Then, the items to be washed in each tank are transferred to the next tank. Among the above-mentioned items to be washed, the items in the 14th tank that have been washed, rinsed, etc. are transferred to the outside of the cylinder 1 through the outlet 11, and are dehydrated in the next dehydration step. Then, the untreated items to be washed are put into the empty first tank of the cylinder 1 through the inlet 10. The unprocessed items placed in this first tank are transferred from the first tank to the 14th tank by the above-mentioned operation, that is, the first pre-wash tank 21, the second pre-wash tank 22, the main wash tank 23, and the rinse tank. It is transferred from the tank 24 and the input port 10 to the output port 11.

On the other hand, the second pre-wash water, the main wash water, and the rinse water flow in a direction opposite to the above-described transport direction of the object to be washed. That is, the second pre-wash water supplied to the third tank flows to the second tank, overflows and is discharged from the first drainage part 51, and the main wash water supplied to the ninth tank flows to the fourth tank. The rinsing water that overflows and is discharged from the second drainage section 52 and is supplied into the 13th tank flows to the 10th tank, and overflows and is discharged from the third drainage section 53.

In this way, the items to be washed are washed by the first pre-wash water, the second pre-wash water, the main wash water, which flow in the direction opposite to the direction in which the items to be washed are transported.
Processes such as washing and rinsing are performed using rinsing water.

Note that the swing angle and swing time of the cylinder 1 are adjusted depending on the items to be washed and the type of dirt.

[The problem that the idea attempts to solve]

However, in the above-mentioned conventional continuous washing machine, the water recovered from the outlet 11 of the cylinder 1 and the dehydrator (not shown), which is relatively less contaminated, is used as the first pre-wash water and the second pre-wash water, and the water is used as the first pre-wash water and the second pre-wash water. It is supplied to the first tank and the third tank, respectively. On the other hand, the water recovered from the third drainage section 53, which is relatively contaminated, is supplied as main washing water to the ninth tank, which is somewhat less contaminated. For this reason, it cannot be said that the recovered water is used effectively, and high-quality treatment cannot be obtained accordingly.

An object of the present invention is to provide a continuous washing machine that can effectively utilize recovered water and perform high-quality processing.

The water collected from the first rinse tank and the second rinse tank is supplied by the first supply unit to the second main washing tank via the supply pipe in the cylinder, and the water collected from the first rinse tank and the second rinse tank is supplied by the second supply unit. , the water is supplied to the first main washing tank via a supply pipe in the cylinder, and the water recovered from the first main washing tank and the second main washing tank is supplied to the cylinder by a third supply section. The water is supplied to the second prewash tank via a pipe, and the water collected from the first rinse tank and the second rinse tank and the water collected from the first main wash tank and the second main wash tank are supplied to the fourth prewash tank.
The water is supplied to the first prewash tank by a supply unit.

The present invention (the invention according to claim 2) is characterized in that a heater is provided in each recovery tank of the first supply section, the second supply section, and the third supply section.

[Effect]

With the above-mentioned configuration, the present invention allows the water collected from the relatively less contaminated cylinder outlet side to be transferred to the relatively less contaminated tank on the cylinder outlet side, while the relatively more contaminated collected water is transferred to the relatively less contaminated tank. Can be sequentially supplied to tanks with many cylinders. Therefore,
Recovered water can be used effectively and processed with high quality.

Further, in the present invention, the temperature of the recovered water in each recovery tank can be adjusted by the motor provided in each recovery tank.
