Description

  The present invention relates to an evacuation apparatus and a processing facility, and more particularly, to an evacuation apparatus for evacuating an abnormal article having a height different from that of a normal article and a treatment facility incorporating the same.

Bottles used as containers for beverages such as beer and sake can be collected from the market and reused after use. The collected bottles can be washed after the labels and films are peeled off, then filled with beverages, and shipped with labels and films again. In such a series of processing, the bottle may break. In particular, there is a tendency that a broken bottle tends to occur in an apparatus called a descherin that peels a film from a bottle. When a broken bottle occurs, the device must be stopped and the operator must remove the broken bottle from the device.
JP 2002-186912 A

  However, the operation of removing the broken bottle is dangerous for the operator. Also, if the operator overlooks the broken bottle, it can be sent to the next process apparatus, causing a malfunction or malfunction of the apparatus.

  As a method of discharging the broken bottle, there is a method of detecting the broken bottle with an electric sensor and driving the discharge mechanism according to the detection signal to discharge the broken bottle.

  However, an electric sensor and a configuration for operating the evacuation mechanism according to a detection signal from the sensor are generally large and the cost of the apparatus is high. In addition, it is necessary to periodically check whether or not the sensor or the evacuation mechanism operates. At this time, it is necessary to stop the production line and to actually pass the test bottle through the evacuation apparatus.

  An object of the present invention is to provide, for example, an evacuation apparatus having a simple configuration and / or a configuration in which the occurrence of a defect can be easily visually recognized and a processing facility incorporating the same.

The rejecting device according to the present invention is configured as a rejecting device that rejects an abnormal article having a height different from that of a normal article. The waste disposal device is arranged as a first conveyor that supports and conveys articles from below, a second conveyor that supports and conveys articles from below, and both of the articles. A first guide and a second guide that are guided from the side of the first conveyor, wherein the first conveyor has a waste area that supports only a part of the lower part of the article from below, and the second guide is located in the waste area. A normal product guide for guiding a portion of a normal article at a predetermined height on the side of the normal article, and the rejecting device falls from the reject area because the side of the abnormal article is not supported by the normal article guide. is configured to,
The normal product guide is a drive-type normal product guide that drives an article in the same direction as the conveyance direction by the first conveyor, and the drive-type normal product guide extends from the waste area to the second conveyor .

  According to a preferred embodiment of the present invention, the width of the exclusion area is, for example, ½ or less of the width of the article.

According to a preferred embodiment of the present invention, it is preferable that the drive-type normal product guide drives the article at substantially the same speed as the conveyance speed of the article by the conveyor.

  According to a preferred embodiment of the present invention, the conveyor is configured to transport bottles, and abnormal bottles are discharged in the discharge area.

  The processing facility according to the present invention is configured as a processing facility for processing an article, and conveys the first and second processing apparatuses for processing the article and the article processed by the first processing apparatus to the second processing apparatus. A transport path, and the evacuation device is disposed in the transport path.

  According to the present invention, it is possible to provide, for example, an evacuation device having a simple configuration and / or a configuration in which the occurrence of a defect can be easily recognized visually and a processing facility incorporating the same.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 and FIG. 2 are diagrams showing the configuration of the evacuation device according to a preferred embodiment of the present invention. 1 and 2 is configured as an apparatus for rejecting an abnormal bottle (abnormal article) having a height different from that of a normal bottle (normal article). An abnormal bottle is typically a bottle that has a different height from a normal bottle due to breaking. In FIG.1 and FIG.2, (a) is the figure which looked at the exclusion apparatus from the conveyance direction side, (b) is the figure which looked at the exclusion apparatus from upper direction.

  The waste disposal apparatus according to a preferred embodiment of the present invention includes a conveyor 10 that supports and conveys a bottle (article) 1 from below, and guides 20 and 30 that guide the bottle 1 from the side. The conveyor 10 is configured as, for example, a table top chain type or a belt conveyor, and includes a drainage region 12 that supports only a part of the lower portion (bottom surface) of the bottle 1 from below. The width (dimension in the direction orthogonal to the conveyance direction) and the length (dimension in the conveyance direction) of the exclusion area 12 can typically be defined by the guide 10. The width of the evacuation region 12 is preferably ½ or less of the width (diameter) of the bottle 1. However, for example, when the conveyor 10 is tilted toward the guide 20, the width of the exclusion region 12 may exceed 1/2 of the width (diameter) of the bottle 1.

  The guide 20 has a normal product guide 20n that guides a portion of a normal bottle at a predetermined height on the side of the evacuation region 12 (the side on which the bottle 1 falls if there is no guide). The height of the portion where the normal product guide 20n guides the bottle 1 can be appropriately determined according to how much abnormality (cracking) occurs and the bottle (that is, the abnormal bottle) is rejected. When the normal product guide 20n is arranged at a high position, even when a relatively small defect occurs, such as when the mouth or neck of the bottle 1 breaks, the bottle can be rejected as an abnormal bottle. . On the contrary, when the guide 20 is arranged at a low position, the bottle is rejected as an abnormal bottle only when a relatively large defect such as the upper half of the bottle 1 is lost.

  Since the side of the normal bottle 1 is supported by the normal product guide 20n as shown in FIG. 1, it is conveyed by the conveyor 10 while its bottom is placed on the conveyor 10 (that is, not discharged). On the other hand, as shown in FIG. 2, since the height of the abnormal bottle 1 is low, the side thereof is not supported by the normal product guide 20n, and falls in the normal product guide 20n side in the rejection region 12 and the rejection region. 12 (conveyor 20) falls (that is, is rejected).

  One feature of the evacuation apparatus according to the preferred embodiment of the present invention is that it has a very simple structure. According to such a configuration, the evacuation device can be easily configured by providing the guides 20 and 30 on the conveyor 10. In addition, the presence or absence of a defect in the evacuation operation can be easily confirmed simply by visually observing the conveyor, the guide, or the like.

  On the other hand, an electric sensor (for example, a photo interrupter) for detecting a broken bottle and a draining mechanism for driving a pressing member or the like based on an output signal of the sensor to push out the broken bottle are provided. The type of evacuation device has a large structure and is expensive. Further, in such a conventional evacuation device, it is necessary to stop the production line and pass a test bottle through the evacuation device in order to confirm the presence or absence of the defect.

  FIG. 3 is a plan view showing a configuration of a transport apparatus in which the evacuation apparatus shown in FIGS. 1 and 2 is incorporated. Since the side of the normal bottle 1 is supported by the normal product guide 20 n in the discharge area 12 of the conveyor 10, the normal bottle 1 is delivered to the next-stage conveyor 150 without falling from the discharge area 12 of the conveyor 10. On the other hand, the abnormal bottle 1 is not supported on the side by the normal product guide 20n in the discharge area 12 of the conveyor 10, and falls down from the discharge area 12 of the conveyor 10 due to its own weight or vibration due to conveyance, etc. It will be rejected. In the example shown in FIG. 3, a part of the continuous guide 20 functions as a normal product guide 20n.

  The normal product guide 20n may be configured as a type that does not drive the bottle as described above, but in this case, as shown in FIG. 4, friction occurs between the bottle 1 and the normal product guide 20n, There is a possibility that the bottle 1 falls to the opposite side in the transport direction. In order to solve such a problem, the normal product guide functions to drive the bottle 1 in the same direction as the conveyance direction of the bottle 1 by the conveyor 10, preferably at substantially the same speed as the conveyance speed of the bottle 1 by the conveyor 10. It is preferable to have.

  FIG. 5 is a plan view showing a configuration example of the evacuation device having a normal product guide having a function of driving the bottle and the transport device. In the configuration example shown in FIG. 5, a drive-type normal product guide 120 is arranged instead of the normal product guide 20n. The drive-type normal product guide 120 has a driving belt 122 hung on pulleys 124 and 125, and drives the bottle 1 at substantially the same speed as the conveyance speed of the bottle 1 by the conveyors 10 and 150. The pulleys 124 and / or 125 are driven by a motor. In the configuration example shown in FIG. 5, the drive-type normal product guide 20 extends to the next-stage conveyor 150 beyond the rejection area 12 of the conveyor 10, but this is because the bottle 1 from the conveyor 10 to the conveyor 150 This is to ensure delivery smoothly and smoothly.

  Various processing apparatuses can be arranged on the upstream side (upstream side of the conveyor 10) and the downstream side (downstream side of the conveyor 150) of the transport apparatus shown in FIG. 3 or FIG. For example, an apparatus for peeling a film from a bottle called a “deshrinker” may be arranged on the upstream side, and a bottle washing machine may be arranged on the downstream side. Alternatively, a bottle washing machine can be arranged on the upstream side, and a filling machine can be arranged on the downstream side. Alternatively, a filling machine can be arranged on the upstream side, and a warming machine can be arranged on the downstream side. Alternatively, a warmer can be arranged on the upstream side, and a labeler (labeling device) can be arranged on the downstream side. Alternatively, a labeler can be arranged on the upstream side, and an inspection machine or a caser can be arranged on the downstream side.

  The above is an example in which the present invention is applied to a processing facility whose handling object is a bottle. However, the present invention is not limited to an environment in which an article whose height can be changed due to breakage or the like can be provided, or for various reasons (for example, It can be used to reject abnormal articles in an environment where articles with different heights can be provided due to manufacturing defects.
