(Filling Machine) (FIGS. 6, 7, and 8) The filling machine 60 is held in the article fixing tool 10 in the process of being conveyed by the conveying conveyor 20 at the filling station of the conveying line. The article 1 can be filled with contents such as detergent.

The filling machine 60 has a filling nozzle 61, a lifting operation device 62, and a control device 63.

The filling nozzle 61 horizontally moves in synchronization with the transfer conveyor 20 at the filling station. Then, the filling nozzle 61 is inserted into the inlet 1A of the article 1 which moves up and down relatively in the course of this lateral movement, and fills the article 1 with detergent and the like.

In the elevating / lowering device 62, an electromagnet 64 extends along the transfer line below the transfer conveyor 20 at the filling station. At this time, the electromagnet 64 is
It is divided into five zones of 64A to 64E, and a magnetic repulsive force is exerted on the magnet 31 provided on the lower surface of the support plate 30 in each of these zones. As a result, the lifting operation device 62
In the process in which the article fixture 10 moves through the filling station, the support plate 30 is moved up and down, and the articles 1 held by the article holding members 14A, 14B, 15A, 15B on the support plate 30 are fed to the filling nozzle 61. Up and down.

Based on the following (1) to (3), the control device 63 controls the power supply voltage of the power supply parts 65A to 65E provided for each of the electromagnets 64A to 64E of the lifting operation device 62.
As a result, the control device 63 determines that the distances h _{1 to} h ₅ between the filling level in the article 1 and the filling nozzle 61 are always constant during filling (h ₁ = h ₂ = h ₃ = h ₄ = h ₅ ). Then, the support plate 30 is moved up and down.

(1) When the article fixture 10 enters the filling station of the filling machine 60, the support plate 30 holding the empty article 1 is generated between the magnet 31 and the electromagnet 64 on the lower surface thereof. The repulsive force causes the article fixture 10 to float up to the rising end. As a result, the filling nozzle 61 reaches near the bottom of the article 1.

(2) When the filling of the article 1 from the filling nozzle 61 is started, the article 1 descends against the magnetic force (repulsive force) between the magnet 31 and the electromagnet 64 as its own weight increases. Go. In the descending process of the article 1, the distances h _{1 to} h ₅ between the filling level in the article 1 and the filling nozzle 61 (FIG. 7).
Is ideal from the viewpoint of preventing foaming. This is particularly important when filling the liquid containing the activator. Therefore, the control device 63 controls the magnetic force (repulsive force) between each of the electromagnets 64A to 64E and the magnet 31 by controlling the power supply voltage to each of the electromagnets 64A to 64E, and reduces the descending speed of the article 1. To control.

(3) Here, when the cross-sectional shape of the bottle which is the article 1 is like the straight, conical or inverse conical shape shown in each of FIGS. 8A, 8B and 8C, the filling nozzle If the discharge flow rate of 61 is constant, those filling levels-
The filling amount curves are as shown in FIGS. 8 (A), (B), and (C).

When the power supply voltage to each of the electromagnets 64A to 64E is controlled so as to have the same curve as the filling level-filling amount curve, the repulsive force between the electromagnet 64 and the magnet 31 is the same. It becomes inversely proportional to the square of the distance r between 31 and is as shown in FIGS. 8 (A), (B) and (C).
It becomes like the repulsive force curve between magnets. Therefore, in the process of filling the article 1, in order to make the distance between the filling level and the filling nozzle 61 constant, the repulsive force to be generated between the electromagnet 64 and the magnet 31 becomes insufficient.

Therefore, the control device 63 adjusts the correction voltage to each of the electromagnets 64A to 64E so as to compensate for the above-mentioned lack of repulsive force as shown in FIGS. 8A, 8B, and 8C. It is controlled to follow. This makes it possible to minimize foaming at the time of filling and ideally fill the article 1 having any cross-sectional shape.

According to the filling machine 60, however,
Has the effect of. In the filling machine 60 that raises and lowers the article 1 held in the article fixture 10 with respect to the filling nozzle 61, it is not necessary to raise and lower the entire article fixture 10, and the article 1 can be raised and lowered. Therefore, the filling machine 60 having good transportability can be configured.

By controlling the raising / lowering operation device 62 of the support plate 30 by the control device, the distance between the filling nozzle 61 and the filling level can be reliably ensured even when the cross-sectional shape of the bottle changes significantly in the vertical direction. Can be kept constant.
