否検査が光学的に行われている。2. Description of the Related Art During the manufacture of glass bottles, so-called cracks or bubbles may occur within the wall thickness of the mouth of the bottle. Regarding air bubbles, small ones may not cause any problems with the product, but the cracks mentioned above are serious defects that can lead to breakage of the glass bottle, so inspection for the presence or absence of such defects can be carried out optically. It is being said.

にして欠陥を検査するようにしている。Conventionally, to optically inspect the presence or absence of this defect, the conveyance of the glass bottle is stopped intermittently in the middle of the conveyance path, and the glass bottle is rotated at the stopped position. A light projector that emits, for example, slit light toward the mouth of a rotating glass bottle is placed on one side in the width direction of the conveyance path, and a light receiver that detects the reflected light that is reflected when there is a defect in the mouth of the glass bottle. A device is provided on the other side in the width direction of the conveyance path, and defects are inspected based on the output when the light receiver receives reflected light.

検知される場合がある。By the way, the above-mentioned cracks occur without directionality, and the direction of reflection of the reflected light with respect to the irradiated light is not determined. For example, under certain optical conditions, the light may If the optical conditions such as the direction of irradiation and the direction of reception of reflected light are slightly changed and light is irradiated, defects may be detected.

組だけでは正確な欠陥検査を行うことができない。[0005] Furthermore, depending on the direction of the crack, the light emitted from the projector may pass through the crack without being reflected by the crack. In other words, accurate defect inspection cannot be performed with only one set of light emitters and receivers.

いる。[Problems to be Solved by the Invention] Conventionally, in order to improve inspection accuracy, a plurality of pairs of light emitters and receivers are arranged in the direction of the transport path, and each set of light emitters and receivers is The light emitting direction and light receiving direction are made different so that defects can be inspected over a wide range under various optical conditions.

た。However, when multiple sets of light emitters and receivers are arranged along the conveyance route, the longer the number of sets of light emitters and receivers arranged, the longer the inspection line becomes. This requires a large number of control means to stop the glass bottle at each stop position and a large number of means to rotate the glass bottle at each of the stop positions, which requires a large amount of equipment space, increases equipment costs, and requires multiple defect inspection sections. There was a problem in that it required a lot of manpower to understand the inspection status from the start.

There was a problem that the direction was easily inconsistent.

御部を設けた点に特徴がある。That is, the glass bottle mouth defect inspection apparatus according to the present invention includes a bottle rotation means for rotating glass bottles sequentially conveyed at a fixed position and around the center of the bottle during the conveyance path of the glass bottles; A slide block whose position can be freely changed in the width direction and the vertical direction of the conveyance path is provided, and light is irradiated onto one side of the conveyance path in the width direction of the slide block toward the opening of the glass bottle rotating at the fixed position. At the same time as attaching a plurality of floodlights to the mouth, and condensing the irradiation light from the plurality of floodlights near the mouth,
A plurality of light receivers are provided on the other side in the width direction of the conveyance path with respect to the slide block for detecting reflected light reflected by the defective portion in the mouth, and further, the plurality of light projectors are sequentially installed one at a time. The emitter control unit repeatedly switches to the light emitting state, and the light receiver, which receives the light emitted from the emitter that has been switched to the light emitting state and reflects or passes through the mouth of a good glass bottle, switches to a non-detecting state. It is characterized by the provision of a receiver control section that controls the

Not only the light that is reflected or transmitted through the glass bottle, but also the light that diffuses when the joint reaches the defect inspection area due to the rotation of the glass bottle is captured by the receiver, which makes it difficult to detect non-defective products. There is an inconvenience in that a glass bottle is judged to be defective.

For example, the circumference is 1 mm during one continuous rotation around the
The plurality of light projectors 17 are sequentially and instantaneously switched to the light projecting state one by one at a pitch of 360 degrees, and each time, the light projectors 17 are turned toward the mouth 2a of the glass bottle 2. Slit light is irradiated from multiple different directions.

正確に行わせることができる。As explained above, according to the glass bottle opening defect inspection apparatus according to the present invention, defects in the opening of a glass bottle can be inspected at multiple points at one point along the conveyance route. Compared to conventional methods, the control means for the conveyance system and the means for rotating the glass bottle are simplified, and the opening of the glass bottle can be moved at a lower cost, in less space, and with less manpower. Defect inspection can be performed accurately over multiple points.
