Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bottling or canning plant or the like in a conveying path for detecting the inverted state of the bottling or canning that is conveyed on the conveying path. The present invention relates to an article detection device.

(Prior Art) As a conventional device of this type, photoelectric tubes are arranged on both sides of a conveyance path, and light is detected from the photoelectric tubes.

FIG. 3 and FIG. 4 show a conventional example of such a detection device, in which a bottle guide (22) and a pair of upper and lower photoelectric tubes (23) (24) are provided on both sides of a conveyor path (21) composed of a conveyor. If there are no bottles in the transport path (21), the phototube (23)
(24) is transparent, the upper and lower photocells (23) and (24) are shielded from light when the erect bottle (25) is in the state shown in FIG. 3, and the inverted bottle (6) is shown in FIG. Lower photocell (2
4) is shielded from light, and the upper photocell (23) becomes light-transmitting.
6) was detected.

(Problems to be solved by the invention) However, even if such a conventional device can easily detect the inversion bottle in the case of a single-row bottle on the transport path, if it is a multi-row bottle on the transport path, It was difficult to detect and could not be applied. For this reason, a detection device using an industrial TV is being researched, but it requires advanced data processing due to the wide range of bottle occurrence locations on the multi-row transport path, the orientation of the bottle collapse, etc. The situation is not widespread.

The present invention is proposed in view of the current situation,
The purpose is to detect an inverted bottle or an inverted can on the multi-row transport path by the distance measurement value.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 and 2 corresponding to an embodiment. , A plurality of detectors (4) consisting of non-contact, reflection type distance measuring devices are arranged in a row at a pitch smaller than the diameter of the article on the conveying path (1), orthogonal to the conveying path (1). Characterize.

(Effect) And, according to the present invention, the upright bottle (2) on the transport path (1) is detected as the distance A by the detector (4) by the above means, and the upright bottle (3) on the transport path (1) is detected. Is detected as a distance B by the detector (4), and a portion without a bottle on the transport path (1) is detected as a distance C by the detector (4), and the presence of the inverted bottle (3) is easily detected. it can.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. (1) shows a conveying path consisting of a multi-row conveyor, and a supporting path is provided above the conveying path (1). Through the member (5), a plurality of detectors (4) consisting of non-contact, reflection type distance measuring devices such as ultrasonic waves and lasers are orthogonal to the conveyance path (1) and on the conveyance path (1). Are arranged in rows that are smaller than the diameter of the article.

The figure shows a state in which bottles are transported in multiple rows on the transport path (1), and the upright bottle (2) and the inverted bottle (3) are the second
When transported in the Y direction in the figure, each detector (4) measures the distance to the reflecting surface simultaneously or sequentially at a predetermined time interval depending on the speed of the transport path (1), the bottle diameter, etc. By this method, the upright bottle (2) shows the distance A by the detector (4) and the inverted bottle (3) shows the distance B by the detector (4).
, And the portion without a bottle indicates the distance C by the detector (4), and the presence of the inverted bottle (3) is detected.

When the inversion bottle (3) is detected, the signal is output, or counting is performed, and the inversion bottle is excluded based on the signal, and various treatments can be performed.

(Effects of the Invention) As described above, according to the present invention, a plurality of detectors, which are non-contact, reflection type distance measuring devices, are arranged above the transport path and are arranged at right angles to the transport path depending on the diameter of the article on the transport path. Since the detectors are arranged at a small pitch, the detectors that are arranged in the upper part of the conveying path at a pitch orthogonal to the conveying path and at a pitch smaller than the diameter of the article are both single-row and multi-row articles. The upright state, the fall of articles, or the absence of articles can be detected without contact to easily detect the falling state of articles, thus helping to automate and save labor for various equipment such as bottle plants and can plants. Has the effect of being able to.
