Description

  The present invention relates to a conveying apparatus that conveys an article while removing foreign matters from the article.

  Beer bottles can be collected from the market in a box and further loaded on a pallet. In a beer factory, boxes loaded on a pallet are lowered from a pallet onto a conveyor by a depalletizer, and then conveyed to an anchor by a conveyor. The answerer takes out the beer bottle from each box and places it on the conveyor.

Various foreign matters such as dust, water droplets, snow, and ice may adhere to boxes or beer bottles collected from the market. If there is snow or ice on the box, the beer bottle may not be removed from the box by the answerer. In addition, for example, there is a demand to inspect boxes and / or beer bottles between a depalletizer and an answerer. However, if various foreign substances such as dust, water droplets, snow, and ice are attached to the box or beer bottle, it is difficult to perform an appropriate inspection. Therefore, conventionally, foreign matters adhering to the box or beer bottle are visually confirmed and removed manually.

  According to a preferred embodiment of the present invention, it is preferable that the transport device further includes a guide disposed along the endless conveyor so as to guide an article. Here, it is preferable that the guide is configured to guide a lower side and a side of the article.

  According to a preferred embodiment of the present invention, the endless conveyor may include a chain conveyor or a belt conveyor.

  According to a preferred application example of the present invention, the article is, for example, a box containing a container.

  According to the transport apparatus of the present invention, for example, foreign matters can be removed from an article while the article is being transported at a high speed.

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

  The transport device according to the present invention can be configured to transport various articles while removing the adhered foreign matter. Hereinafter, in order to provide a more specific example, the transport device of the present invention is a bottle. An example will be described in which a box containing a container is applied to an apparatus that conveys a box while removing foreign matter adhering to the box.

  1 to 3 are views showing a configuration of a transport apparatus according to a preferred embodiment of the present invention. FIG. 1 is a side view in which the front-side structure (guide) is omitted, and FIG. 2 is a plan view. FIG. 3 is a cross-sectional view seen from the conveying direction. The transport apparatus 100 of this embodiment is configured to transport the box 90 while removing foreign matters such as dust, water droplets, snow, ice, and the like from the box 90 in which the bottle container 90 is accommodated. The transport apparatus 100 can be applied to all or a part of a path for transporting a box between a depalletizer and an anchorer in a beverage manufacturing factory such as a beer factory.

  The transport device 100 swings the endless conveyor 10 that transports the box 90 in which the bottle containers 92 are accommodated, and the box 90 that is being transported by the endless conveyor 10, to shake off foreign matter from the box 90 or the bottle container 92. And a rocking mechanism 60. The endless conveyor 10 can be configured by, for example, a chain conveyor or a belt conveyor. By employing the endless conveyor 10 for transporting the box 90, the box 90 can be transported at a higher speed than the transport method using vibration as shown in Patent Document 1. Also, typically, in a beverage manufacturing factory, an endless conveyor is used to convey a box. Therefore, by incorporating a swing mechanism 60 into an existing endless conveyor, a foreign matter removing mechanism can be made relatively easily. Can be introduced.

  The transport apparatus 100 preferably includes a guide member that guides the box 90 in order to prevent the box 90 from falling from the endless conveyor 10 due to the swinging of the box 90. A guide member is arrange | positioned along the endless conveyor 10, for example, can be comprised so that the downward direction and the side of the box 90 may be guided. In the configuration example shown in FIGS. 1 to 3, the guide member includes two rows of first guides 30 that guide the lower side of the box 90 and two rows of second guides 40 that guide the side of the box 90 from both sides. Is arranged.

  The swing mechanism 60 includes an eccentric cam 20 and swings the box 90 that is an article to be conveyed by rotating the eccentric cam 20. The eccentric cam 20 can be disposed, for example, below the conveyance path of the box 90 and on the side of the endless conveyor 10. The eccentric cam 20 is eccentrically fixed with respect to the rotating shaft 22. A gear 28 is fixed to the rotary shaft 22, and a rotational force is transmitted from the motor 24 via the pinion gear 26. While the eccentric cam 20 makes one rotation, the box 90 is swung around the vertical direction and an axis orthogonal to the transport direction.

  In the configuration example shown in FIGS. 1 to 3, eccentric cams 20 are fixed on both sides of the rotating shaft 22. The two eccentric cams 20 are preferably arranged on both sides of the endless conveyor 10 so as to sandwich the endless conveyor 10. In other words, the endless conveyor 10 is preferably arranged so as to pass between the two eccentric cams 20. According to such an arrangement, the driving force of the endless conveyor 10 is transmitted to the box 90 in the vicinity of the center line, thereby reducing the conveyance loss.

  In the configuration example shown in FIGS. 1 to 3, the eccentric cams 20 arranged on both sides of the endless conveyor 10 face the same direction (direction around the rotation shaft 22). Therefore, even if the eccentric cam 20 rotates, the box 90 does not easily rotate around the axis along the transport direction (x direction). However, as illustrated in FIG. 4, the box 90 may be rotated around an axis along the transport direction (x direction) in accordance with the rotation of the eccentric cam 20. In the configuration example shown in FIG. 4, the two eccentric cams 20 face different directions (directions around the rotation shaft 22).

  The mechanism for swinging the case 90 is not limited to the configuration using the eccentric cam. For example, the case 90 may be swinged by applying a force to the case 90 by an actuator such as an air cylinder or a hydraulic cylinder.
