A device (also referred to as a first static electricity removing device) 11 and a second static electricity removing means, which is a second static electricity removing means for removing static electricity from the workpiece w by blowing ionized air onto the workpiece w located at the outlet 7 at the end of the workpiece passage 4. And a power unit 13 for supplying a high voltage to the first and second static electricity removing devices 11 and 12.

The left half of FIG. 1 depicts the container 1 and the work passage 4 in a front section, and further on the right side of the container 1 in order to clarify the arrangement of the first static eliminator 11 with respect to the container 1. The cross section taken along line AA is drawn. Therefore, in this sense, FIG. 1 is a composite diagram as a whole, and is an explanatory diagram of the alignment apparatus according to the present embodiment.

The container 1 has a cylindrical shape with its central axis oriented horizontally, and has a peripheral wall 1a and a pair of end walls 1b, 1c.
And an intake port for a work w (not shown), and is supported by support means (not shown). In addition, the peripheral wall 1a
An arc-shaped surface 2 is provided on at least a part of the inner surface of the arc-shaped surface 2, and the workpiece w rolls along the arc-shaped surface 2 and is taken in the work passage 4 in a tangential direction of the arc-shaped surface 2. A work passage 4 is horizontally connected to the upper part of the container 1.

The work passage 4 is a straight hollow passage having a rectangular cross section, and has a bottom wall 4a, a top wall 4b, and a pair of side walls 4c, 4d (see FIG. 3). An opening 5 is provided, and at the other end (end), a stopper 6 for stopping the work w and an outlet 7 for taking out the work w upward or in the front-back direction are provided.

The container-side opening 5 is provided with a work w so that the work w does not enter the work passage 4 in a state of being overlapped.
It has a size that allows only one work w to pass through, and the opening cross section of the work passage 4 also has a size that allows only one work w to pass so that the works w can be arranged in a line.

An air inlet 3 is provided on the peripheral wall 1a of the container 1. When an air ejecting device (not shown) is operated and air is blown into the container 1 from the air inlet 3 at a high pressure,
The work w rolls in the container 1 on the momentum, rotates counterclockwise in the figure, and rolls along the arc-shaped surface 2,
One work w whose orientation matches the container side opening 5 is taken into the work passage 4 from the container side opening 5 and thereafter, this is repeated, and the works w are successively moved one by one from the container side opening 5 to the work passage. 4

The above-described first static electricity removing device 11 is attached to the outside of the container 1 and at the center of one end wall 1b, and the ionizing air supply port 8 provided in the end wall 1b is connected to the first static electricity removing device 11 from this device 11. The ionized air is supplied into the container 1 via the container. The second static electricity eliminator 1 is provided outside the work passage 4 and above the outlet 7.
2 is attached via a bracket 9, and ionized air is blown from the device 12 toward the outlet 7 or the work w located at the outlet 7.

First and second static eliminators 11, 1
2 are as follows.

That is, as shown in FIG. 2, first, the input voltage (100 to 200 V AC) is boosted to a high voltage by the power unit (transformer transformer power unit) 13, and a high voltage is applied to the neutralizing electrode 15 through the high voltage cable 14. A high-voltage electric field is generated between the electrode and the charge removing electrode 15, and the air is ionized, and the ionized air is supplied into the container 1 or is blown to the outlet 7 or the work w located at the outlet 7. The ionized air has both positive and negative ions due to the AC electric field. Therefore, ions having a polarity opposite to the charge polarity of the work w are attracted and adhere to the surface of the work w to neutralize the charge. .

In the aligning apparatus having the above-described configuration, a predetermined amount of the work w is accommodated in the container 1 and air is blown into the container 1 from the air blowing port 3 at a high pressure by operating an air ejection device (not shown). At the same time, the first static eliminator 11

The work w in the container 1 is completely separated one by one by the supply of ionized air to remove static electricity, and is sent to the work passage 4 by the force of the flow of the blowing air. As shown in the figure, the fluid smoothly flows in the work passage 4 and is received by the stopper 6. This operation is performed until the work w is fully filled in the work passage 4 to align the work w in a line, and the work w is waited for being taken out one by one from the outlet 7.

At the time of the removal, the second static electricity removing device 12 is operated to blow ionized air toward the outlet 7 or the work w located at the outlet 7, thereby removing the static electricity. The work w can be smoothly taken out.

With respect to the installation position or quantity of the static eliminators 11 and 12, there are the following cases.

A. If the ionized air can be supplied into the container 1, the installation position of the static electricity removing device 11 is arbitrary. Therefore, it may be appropriately installed in accordance with the installation environment or the like. b. Static electricity removing device 1 according to the size (capacity) of container 1
There may be a case where one and a plurality of ionized air supply ports 8 are provided. c. The static eliminator 11 may be provided with an ionized air supply port 8 provided above the work passage 4. in this case,

The timing of blowing air into the container 1 and supplying ionized air into the container 1 may be intermittent.

In some cases, the pressure of the air blown into the container 1 and the pressure of the ionized air supplied into the container 1 may be changed alone or the same.

[0029]

The present invention has the following effects.

That is, in the aligning apparatus according to the first aspect of the present invention having the above-described structure, ionized air is supplied into the container from the static electricity removing means, and the ions of the ionized air adhere to the work, thereby charging the work. Due to the neutralization, it is possible to prevent the works from being completely separated one by one and sticking on two layers or sticking to the inner surface of the container or the work passage. Therefore, the work of aligning or taking out the work can be stabilized, and the work supply cycle in the production line or the operation efficiency of the production line can be improved.

In addition, in the aligning apparatus according to the second aspect of the present invention having the above structure, ionized air is blown from the second static electricity removing means to the work located at the outlet at the end of the work passage. Since the ions of the ionized air adhere to the work and the charge of the work is neutralized, the above-described effect in the removal operation is further promoted.
