Abstract

[Problem] To provide a moving device that can move a container and return the moved container to a predetermined position and orientation. [Solution] The moving device 21 comprises a moving body 30 and a drive unit 31. The moving body 30 has an extrusion section 32 and a push-back section 33, and the distance between the extrusion section 32 and the push-back section 33 is wider than the distance between the contact portions of the first side surface 14a and the second side surface 14b of the container 14. The fixed position of the moving body 30 is defined as the position where the extrusion section 32 and the push-back section 33 are separated from the contact portions of the first side surface 14a and the second side surface 14b of the container 14, which is in a predetermined position on the placement section 26. When the drive unit 31 moves the moving body 30 from the fixed position in the extrusion direction A back to the fixed position, it moves the moving body 30 to be moved in the push-back direction B past the fixed position to a position where the container 14 is sandwiched between the push-back section B and the guide section 27, and then moves it in the extrusion direction A back to the fixed position.

Description

This invention relates to a mobile device, a conveying device, and a picking system. Conventionally, a picking device using a conveying device, such as the one described in Patent Document 1 below, is known. In this picking device, multiple containers are conveyed by the conveying device, and the worker places the picked items into the designated containers, thereby filling the containers with items. Japanese Patent Publication No. 2011-173664 This is a plan view of a picking system equipped with a moving device and a conveying device, which shows one embodiment of the present invention.This is a plan view showing the containers moved to the work area of the picking system described above.This is a plan view of the same moving device.A side view of the same moving device.(a) to (d) are side views showing the operation of the above-mentioned moving device.The operation of the above-mentioned moving device is shown in the plan views (a) to (e). Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 show plan views of the picking system 10. The picking system 10 is used in a picking operation where an operator 12 retrieves ordered items from the items stored in the item storage section 11, and then sorts and places the retrieved items into order-specific collection containers 14, which are transported by a conveying device 13. The containers 14 are transported by the conveying device 13. The conveying device 13 has multiple zones Z along the conveying direction F where workers 12 perform picking operations, with one worker 12 assigned to each zone Z. Within each zone Z, an item storage section 11 is installed on one side of the intersecting direction W, which intersects the conveying direction F of the conveying device 13, flanking a work area 15 where the workers 12 perform picking operations. The work area 15 is a range that may include the body of the worker 12 during picking, and is a fixed area that extends in accordance with the transport direction F and the intersecting direction W that intersects this transport direction F. For example, a rectangular virtual area can be defined as the work area. Furthermore, the item storage section 11 is, for example, a shelf, where items are stored by type in each section of the shelf, and the worker 12 can retrieve items to be picked from the item storage section 11. Furthermore, the conveying device 13 includes a conveying unit 20 that conveys the container 14 in the conveying direction F, and a moving device 21 that moves the container 14 between the conveying unit 20 and the work area 15. The conveying section 20 uses a roller conveyor comprising a frame 23 and a plurality of rollers 24 arranged parallel to the frame 23 along the conveying direction F to convey the containers 14 in the conveying direction F. A conveying surface 25 is configured on the upper side of the plurality of rollers 24 to support and convey the bottom surface of the containers 14. The conveying section 20 has a predetermined number of placement areas 26 in each zone Z, where a predetermined number (e.g., 6) of containers 14 are arranged along the conveying direction F, and each placement area 26 functions as an accumulating conveyor capable of conveying and stopping the containers 14. Alternatively, a stopper may be placed downstream of the conveying direction F in zone Z to stop the conveying of the containers 14, allowing a predetermined number of containers 14 to be stopped collectively and placed in each placement area 26. The goal is simply to ensure that a predetermined number of containers 14 can be loaded, stored, and unloaded from the conveying section 20 within zone Z. The transport unit 20 has a guide unit 27 positioned along the transport direction F on the opposite side of the work area 15 in the intersecting direction W that intersects the transport direction F. The guide unit 27 is positioned above the roller 24 (transport surface 25) and is supported by the frame 23 by multiple arms 28 (see Figure 4). The guide unit 27 is positioned at a height where the upper side of the container 14 can make contact. By pressing the side of the container 14 parallel to the longitudinal direction of the guide unit 27, it also functions as a position and orientation correction unit, correcting the position and orientation (hereinafter referred to as "position and orientation") of the container 14 to a predetermined position and orientation that allows it to be transported by the transport unit 20. Furthermore, the moving device 21 is installed corresponding to the position of the upstream placement section 26 in the transport direction F of each zone Z, and moves the container 14 between a position on the placement section 26 (see Figure 1) and a position protruding into the work area 15 (see Figure 2). Furthermore, as shown in Figures 3 and 4, the container 14 is a box-shaped container with an open top, capable of holding item
