Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous rotary bottle inspector used for inspecting deformed glass bottles at high speed.

[0002]

2. Description of the Related Art Conventional rotary glass bottle inspectors are equipped with a large number of bottle holders around a rotating disk and send the bottles to the inspection position for inspection, and stop the bottles at the inspection position. The intermittent rotation type was common because it was necessary to make it work. Therefore, the acceptance of bottles in the holder, the bottle inspection at the inspection position, and the removal of the bottles from the holder have been performed while the turntable is stopped.

However, in such an intermittent rotation type bottle inspection machine, vibration is inevitably generated when the indexer drives the rotary disk intermittently, and the bottle inspection capacity is 150 minutes per minute due to the intermittent rotation. There are drawbacks such as difficulty in making more than the number of books. In addition to the round bottle, in the case of a deformed bottle such as an elliptical bottle, it is necessary to completely take in the bottle inside the holder, and the holder must be opened and closed greatly at the bottle take-in and take-out positions. , This operation must be performed while the turntable is stopped, so it is necessary to rotate the holder opening / closing cam separately from the turntable.
There was also a problem that the mechanism became complicated.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, has less vibration, and can improve the inspection capability as compared with the prior art. Further, the holder opening / closing uses the rotation of the turntable. It was completed to provide a continuous rotary bottle inspection machine that can be operated.

[0005]

SUMMARY OF THE INVENTION A continuous rotary bottle inspecting machine of the present invention made to solve the above-mentioned problems has a structure in which a continuously rotating rotary disk is surrounded by two upper and lower conjugate cams. A large number of rocking bases that can be rocked are pivotally mounted, and each rocking base is rocked toward the inspection position before and after the inspection position, and it is slid on each rocking base in the radial direction according to the rocking angle. A bottle holder that stops at the inspection position while the turntable rotates by a predetermined angle is provided.

[0006]

The continuous rotary bottle inspector of the present invention has a large number of bottle holders mounted on a continuously rotating turntable.
Compared to the intermittent rotation type, there is less vibration and high speed inspection is possible. Moreover, the center of the bottle holder is stopped at the inspection position while the turntable rotates by a predetermined angle by swinging the rocking table toward the inspection position before and after the inspection position and sliding the bottle holder in the radial direction. Since it is possible to perform the inspection, the bottle can be inspected in the same state as the intermittent rotation type. In addition, at the bottle take-in and take-out positions, the rotation of the turntable can be used to easily open and close the bottle holder with the cam fixed to the main body.

EXAMPLES The present invention will be described in more detail below with reference to examples. FIG. 1 is a plan view of a continuous rotation type bottle inspecting machine according to the present invention, in which 1 is a turntable which continuously rotates clockwise and 2 is a bottle holder. Reference numeral 3 is a bottle feeder, 4 is a bottle take-out machine, and the bottles supplied to the bottle holder 2 by the bottle feeder 3 are A, B, C,
Each portion is inspected at six inspection positions D, E, F, and is taken out by a bottle take-out machine 4 onto a conveyor (not shown).

In the present invention, the bottle holder 2 is not directly attached to the turntable 1. That is, as shown in FIG. 2, first, a large number of rocking bases 5 are pivotally mounted around the turntable 1 so as to be able to swing with respect to the turntable 1 about a shaft 6. The linear motion guide 7 on the upper surface of the swing base 5
A slider 8 which is slidable in the radial direction of the turntable 1 (including a case where it is strictly displaced from the radial direction due to the rocking of the rocking table 5) is supported on the upper surface of the slider 8. Two are pivotally attached.

As shown enlarged in FIGS. 3 and 4, the rocking base 5 has T-shaped arms on both sides of a shaft 6, and is provided with upper and lower two stages of cam rollers 9a and 9b at both ends thereof. ing. The cam rollers 9a and 9b are in contact with upper and lower two-stage conjugate cams 10a and 10b fixed to the main body of the inspection machine. At the bottle taking-in position shown in FIG. 3 and the bottle taking-out position shown in FIG. 4, since the upper and lower two-stage conjugate cams 10a and 10b are both arcuate surfaces having the same radius, the cam rollers 9a and 9b are arranged on the turntable 1. The rocking table 5 is aligned perpendicular to the radial line and faces the radial direction of the turntable 1.

Each bottle holder 2 is provided with an opening / closing roller 11 near its base, and this opening / closing roller 11 is engaged with a grooved cam 12 for opening / closing the holder, which is fixed to the upper part of the main body of the inspection machine. .. Therefore, if the shape of the groove cam 12 is designed as shown in FIGS. 3 and 4, the bottle holder 2 opens and closes at the bottle intake position and the bottle extraction position, and receives the bottle from the bottle supply machine 3 and the bottle removal machine. You can release a bottle on the 4th.

As described above, at the bottle taking-in position and the bottle taking-out position, the rocking base 5 faces the radial line direction of the turntable 1 and the bottle holder 2 moves at a constant speed, but before and after the inspection position. In the case of FIG.
It is designed to swing with respect to. Therefore, before and after the inspection position, upper and lower conjugate cams 10a and 10b are formed as uneven surfaces, and the bottle holder 2 faces the inspection position before the inspection position as shown in FIG. The bottle holder 2 swings forward, and as shown in FIG. 7, the bottle holder 2 swings backward toward the inspection position behind the inspection position. As a result, in the section of FIGS.
Bottle holder 2 despite rotating at a constant speed
Will stop at the inspection position.

However, as described above, the center of the bottle holder 2 cannot be accurately stopped at the inspection position simply by swinging the swing base 5 toward the inspection position.
This is because when the rocking base 5 is rocked, the distance between the shaft 6 and the inspection position changes. Therefore, in the present invention, the expanding cam 13 is provided corresponding to each swing table 5. The expanding cam 13 is fixed to the rotary disc 1, and an expanding cam roller 14 provided on the slider 8 is engaged with the expanding cam 13. Therefore, when the oscillating table 5 oscillates with respect to the turntable 1 as described above, the slider 8 moves in the radial direction of the turntable 1 according to the cam curve of the expanding cam 13, and the center of the bottle holder 2 is moved. Stop exactly at the inspection position. This state is schematically shown in FIG.

As described above, at each inspection position, the bottle holder 2 is stopped while the turntable 1 is rotated by a predetermined angle,
During this time, the bottle can be rotated inside the bottle holder 2 to inspect each part. In the embodiment, the elliptical bottle is rotated inside the bottle holder 2 having an inner diameter substantially equal to its major axis,
In the case of a round bottle, the shape of the bottle holder 2 can be simplified.

[0014]

As described above, in the continuous rotary bottle inspecting machine of the present invention, the bottle holder 2 alone can be stopped at each inspection position while continuously rotating the turntable 1 at a constant speed. it can. For this reason, there is no vibration compared to the conventional intermittent rotation type, and the bottle inspection capacity per minute is 200
It can be improved to more than a book. Further, since the continuous rotary bottle inspecting machine of the present invention can take in and take out bottles while rotating the turntable 1, the bottle holder opening / closing groove cam 12 fixed to the inspecting machine body facilitates the bottle holder. 2 can be opened and closed, and it is not necessary to rotate the holder opening / closing cam separately from the turntable 1 as in the conventional case. Therefore, the present invention has a great contribution to the industry as a continuous rotary bottle inspection machine that solves the conventional problems.
