DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of aligning and aligning small cap-like equipment (hereinafter, sometimes simply referred to as "cap") such as a bottle cap in a certain direction, and performing the next step of bottling. The present invention relates to an apparatus for arranging small cap-like materials for supply.

[0002]

2. Description of the Related Art Conventionally, as a device for arranging cap-like small equipment, for example, a device in which a cap is aligned in a row by a vibration feeder and moved in the opposite direction, and the cap is dropped by a drop groove or the like, a peripheral device of an inclined disk, etc. And a structure in which the compressed air is ejected from the small holes formed to align the caps, and a structure in which the caps are aligned in a line by rotating the inclined disk to remove defective products when sent out from a straight discharge guide.

[0003]

Among these, those using a vibration feeder require the entire apparatus to have a shape conforming to the size of the cap depending on the size of the cap, and the selection speed is slow, and troubles such as clogging occur. And other problems. In addition, the one that ejects compressed air from small holes formed around the inclined disk is one that aligns with the cap facing upward, but the top part of the cap (the upper surface when the cap is facing downward) is In general, the alignment device has a bulged shape, and the posture becomes unstable if the cap is aligned upward.Therefore, this alignment device has a problem that the top portion of the cap is limited to a flat shape. there were. In addition, since the cap is sent upward, downward, or sideways due to the rotation of the inclined disk, it is necessary to remove approximately 2/3 of the remaining caps in order to remove the necessary downward one from the cap. Yes,
There are problems such as poor efficiency and the need to specialize the device depending on the size of the cap.

The present invention has been made in view of the above-mentioned problems of the conventional apparatus for arranging small cap-shaped devices, and ensures that cap-shaped small devices are aligned in a certain direction by reliably and efficiently taking out only downward facing caps. It is another object of the present invention to provide an apparatus for arranging cap-like small equipment which can be supplied to a subsequent bottling step or the like.

[0005]

In order to achieve the above-mentioned object, a cap-like small device aligning apparatus according to the present invention is arranged along a cylindrical outer wall installed at an angle and a bottom inner peripheral surface of the outer wall. A hollow member provided with a vacuum chamber therein and having an upper opening formed with an opening groove communicating with the vacuum chamber, and rotatably disposed on the upper surface of the hollow member, via the opening groove of the hollow member. A rotating disk having a small hole communicating with the vacuum chamber formed closer to the outer periphery of the rotating disk than the radius of the cap-shaped small device, a supply pipe for supplying the small cap-shaped device to the upper surface of the rotating disk, and a rotating disk. Out of the cap-shaped small equipment sucked at the position where the small hole is drilled, except for the one that has been sucked downward, the pressure air ejection pipe that blows down, and the cap-shaped small equipment that is sucked on the rotating disk And a discharge pipe to be taken out .

[0006]

Among the small caps supplied to the upper surface of the rotating disk, the upwardly facing cap-shaped small equipment has a small hole formed nearer to the outer periphery of the rotating disk than the radius of the cap-shaped small equipment. As a result, the small hole is located at a position shifted from the center position of the cap-shaped small device, so that the small hole is not adsorbed on the rotating disk, and the horizontal cap-shaped small device is in line contact with the rotating disk. Therefore, it is not adsorbed on the rotating disk. Then, the cap-shaped small devices adsorbed to the rotating disk are further blown down by the jet air from the compressed air jet pipe, except for the downwardly directed cap-shaped small devices firmly adsorbed to the rotating disk, and rotated. Only the small cap-shaped device that has been adsorbed downward on the disk can be taken out of the discharge pipe.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus for aligning small cap-like materials according to the present invention will be described below with reference to the drawings. The apparatus 1 for aligning small caps includes a cylindrical outer wall 15 installed at an angle, a ring-shaped hollow member 3 disposed along the inner peripheral surface at the bottom of the outer wall 15, and an upper surface of the hollow member 3. Of the rotating disk 2 rotatably arranged, the supply pipe 13 for supplying the cap W to the upper surface of the rotating disk 2, and the cap W adsorbed at the position where the small hole 10 of the rotating disk 2 is drilled, Pressurized air blow-out tube 2 to blow down except for adsorbed material
0, and a discharge pipe 14 for taking out the cap W adsorbed on the rotating disk 2 to the outside. In this case, the hollow member 3 is provided with a vacuum chamber 8 inside, and an annular opening groove 6 communicating with the vacuum chamber 8 is formed in an upper portion thereof, and the inside of the vacuum chamber 8 is appropriately connected via a connection pipe 7. They are connected by suction means (not shown). In the rotating disk 2, small holes 10 communicating with the vacuum chamber 8 through the opening groove 6 of the hollow member 3 are formed in the periphery at appropriate intervals.
, And is rotatably supported by the housing 5 so as to rotate leftward in FIG. 1 by an appropriate driving mechanism (not shown). The small hole 10 is formed closer to the outer periphery of the rotating disk 2 than the radius of the cap W. On the upper surface of the hollow member 3, annular packings 11 and 12 are arranged on the inner and outer circumferences with the annular opening groove 6 interposed therebetween.
The packings 11 and 12 have high abrasion resistance, and
It is made of a material that is easy to slip so that the rotation of the rotating disk 2 is allowed and the airtightness between the vacuum chamber 8 of the hollow member 3 and the rotating disk 2 can be maintained.

A supply pipe 13 for supplying a cap W to the upper surface of the rotating disk 2 is provided above the rotating disk 2, and a cap W which is sucked and transferred by the small hole 10 is scooped at an upper position. By receiving and tilting as
Discharge pipe 14 for automatically sending out of the apparatus is provided. A cover 16 is detachably mounted on the upper part of the outer wall 15.
To be installed.

[0009] Next, the operation of the above-mentioned cap-like small device aligning apparatus 1 will be described. Rotating disk 2 from supply pipe 13
Among the many caps supplied on the upper surface of the hollow member 3
As shown in FIG. 4, the downwardly facing cap W located on the small hole 10 communicating with the vacuum chamber 8 through the opening groove 6 is adapted to suck air inside the cap W through the small hole 10. As a result, it is strongly adsorbed on the rotating disk 2.

On the other hand, as shown in FIG. 5, the upwardly facing cap W usually has a shape in which the top portion Wa is bulged, and the small hole 10 has a rotating disk 2 larger than the radius of the cap W. The cap W is not adsorbed on the rotating disk 2 because the small hole 10 is positioned off the center of the cap W by being drilled close to the outer circumference of the cap W.

Further, as shown in FIG. 6, the cap W is in line contact with the rotating disk 2, so that the cap W is not attracted to the rotating disk 2.

Further, even if the upward or sideways caps W are sucked onto the rotating disk 2, these caps W are formed through the small holes 10 through the small holes 10 like the downward caps W. Since the air is not sucked, it is not strongly adsorbed on the rotating disk 2, and the pressure W from the pressure air ejection pipe 20 disposed in front of the discharge pipe 14 for taking out the cap W adsorbed on the rotating disk 2 is taken out. It is blown down by the jet air and does not reach the discharge pipe 14. At the lower position of the rotating disk 2, the posture of the blown-down cap W changes while rolling with the rotation of the rotating disk 2, and the cap W is sucked onto the rotating disk 2 again.

As described above, of the caps W supplied to the upper surface of the rotating disk 2, the upwardly facing cap W
Is drilled closer to the outer periphery of the rotating disk 2 than the radius of the cap W, so that the small holes 10 are shifted from the center position of the cap W.
The cap W in the horizontal direction is not adsorbed on the rotating disk 2 because the cap W is not in contact with the upper side and is in line contact with the rotating disk 2. Then, the cap W adsorbed on the rotating disk 2
Further, the downwardly directed cap W which is firmly adsorbed to the rotating disk 2 by the jet air from the pressurized air jet pipe 20
, Only the cap W blown down securely and adsorbed downward on the rotating disk 2 can be taken out of the discharge pipe 14 to the outside.

[0014]

According to the apparatus for aligning cap-like small devices of the present invention, among the cap-like small devices supplied to the upper surface of the rotating disk, the upwardly facing cap-like small devices have the small holes of the cap-like small devices. By being drilled closer to the outer circumference of the rotating disk than the radius, the small holes will be shifted from the center position of the cap-shaped small equipment, so it will not be adsorbed on the rotating disk, The horizontal cap-shaped small device is not adsorbed on the rotating disk because it is in line contact with the rotating disk. Then, the cap-shaped small devices adsorbed on the rotating disk are further blown down by the jet air from the pressure air jet pipe, except for the downwardly directed cap-shaped small devices firmly adsorbed on the rotating disk, and rotated. Only the small cap-shaped device that has been adsorbed downward on the disk can be reliably and efficiently taken out of the discharge pipe.
