[0008]
Furthermore, as the number of units that require simultaneous water supply increases, more time is required to replace the water supply hose, resulting in a greater loss time. In addition, the conveyor becomes longer and it is necessary to secure a wide working space.
[0009]
As a result, when increasing the production of products in the production line, it is necessary to reduce the loss time in the water supply process and supply water simultaneously.
[0010]
The present invention has been made in view of such problems, when replacement liquid supply hose to the product, the liquid supply that can the be supply fluid to the product by reducing the loss time due to entanglement of the liquid supply hose A liquid supply method using a mechanism is provided.
[0011]
[Means for Solving the Problems]
The present invention comprises a liquid distribution unit that supplies liquid, and a plurality of liquid supply units that are radially connected to the liquid distribution unit via rotary joints, each having a liquid supply hose. production with liquid supply step of the liquid supply mechanism supplies the liquid to the product inspecting or cleaning products for each liquid supply through the respective liquid supply hose to the number multiple pieces of product by rotating the liquid supply portion Te A liquid supply method using a liquid supply mechanism that is arranged in a line and sequentially supplies a plurality of products on the production line via a liquid supply mechanism, wherein a part of the conveyor in the production line is U-shaped or It is formed in a circular arc shape, the liquid distribution part of the liquid supply mechanism is arranged on the substantially central position, and at least one worker is arranged inside the U-shaped or circular conveyor. It is a feature.
[0016]
According to the present invention, a product conveyed through a conveyor is encountered in a liquid supply process such as operation of a production line of a product that handles liquids such as water, liquid leakage, inspection of a liquid supply valve, or cleaning. Rotate the liquid supply part with respect to the liquid distribution part to the position where the liquid is supplied, attach the liquid supply hose to the product, and supply liquid, while stopping the liquid supply to the position where the product separates from the liquid supply part Can be removed.
[0017]
As a result, it is possible to reliably prevent the liquid supply hoses from being entangled when the liquid supply hose is replaced in the liquid supply process, and to reduce the loss time associated with the liquid supply hose entanglement.
In addition, a part of the conveyor in the production line is formed in a U shape or an arc shape, and the liquid supply portion of the liquid supply mechanism is disposed substantially at the center position, so that the liquid supply hose per unit can be replaced. Since the time required for liquid supply does not change, even if the number of units that require simultaneous liquid supply increases, it can be handled by increasing the liquid supply part, and the increase in the floor area of the liquid supply process is minimized. Can be done in a space-saving manner. Furthermore, since at least one worker is arranged inside the U-shaped or arc-shaped conveyor, the interval between the position where the liquid supply unit encounters the product and the position where the liquid supply unit separates from the product is increased. The operator needs to move a minimum distance. For this reason, the remaining time can be allocated to other work until the product reaches a position where it encounters the liquid supply unit.
