Abstract

An article transfer device is configured to transfer a plurality of articles from a placement component to a container. The placement component includes a placement surface on which the plural articles are placed. The article transfer device includes a placement component drive unit that relatively moves the container and the placement component and a control unit that controls the operation of the placement component drive unit. The control unit controls the operation of the placement component drive unit so that, when the articles on the placement component are above the container, the placement component is pulled out from between the container and the articles.

First claim

What is claimed is:

1. An article transfer device that transfers a plurality of articles from a placement component to a container, the placement component having a placement surface on which plural articles are placed and then moved directly into a container, the article transfer device comprising:
a drive unit configured to relatively move the container and the placement component; and
a control unit configured to control the operation of the drive unit,
the control unit is configured to control the operation of the drive unit so that, when the articles on the placement component are above the container, the placement component is pulled out from between the container and the articles, the placement component further having a plate-shaped first member that has a first end and a second end, with the placement surface extending between the first end and the second end, the container including a bottom wall and side walls that are disposed surrounding the bottom surface forming in the container a containment space that is dimensioned to contain the articles, and
the control unit being configured to control the operation of the drive unit to change an angle defined between the placement surface of the first member and the bottom surface of the container when transferring the articles from the placement component to the container so that the first end of the first member is disposed in a lower position than the second end of the first member and in the containment space positioned lower than a top of the side walls.

2. The article transfer device according to claim 1 , wherein the control unit is configured to relatively move the first end of the first member relatively in a first direction in the containment space to proximate the side wall of the container a downstream side in the first direction when the control unit controls the operation of the drive unit so that the placement component is pulled out from between the container and the articles.

3. The article transfer device according to claim 2 , wherein the control unit is configured to move the first end of the first member relatively along the bottom surface of the container to the neighborhood of the side wall of the container disposed on the downstream side in the first direction when the control unit controls the operation of the drive unit so that the placement component is pulled out from between the container and the articles.

4. The article transfer device according to claim 2 , wherein the control unit is configured such that when controlling the operation of the drive unit so that the placement component is pulled out from between the container and the articles, the first end of the first member relatively moves from proximate the side wall of the container on an upstream side in the first direction to proximate the side wall of the container disposed on the downstream side in the first direction.

5. The article transfer device according to claim 2 , wherein
the placement component further includes a plate-shaped second member that has a third end, a fourth end, and the placement surface that extends between the third end and the fourth end,
the control unit is configured to control the operation of the drive unit to change the angle defined between the placement surface of the second member and the bottom surface of the container so that the third end of the second member is disposed in a lower position than the fourth end of the second member and in the containment space positioned lower than the top of the side walls when transferring the article from the placement component to the container, and
the control unit is configured such that when controlling the operation of the drive unit so that the placement component is pulled out from between the container and the articles, the third end of the second member relatively moves in a second direction opposite to the first direction in the containment space to a neighborhood of the side wall of the container disposed on a downstream side in the second direction.

6. An article transfer device that transfers a plurality of articles from a placement component to a container, the placement component including a placement surface on which plural articles are placed and then moved directly into a container, the article transfer device comprising:
a drive unit configured to relatively move the container and the placement component and
a control unit configured to control the operation of the drive unit so that when the articles on the placement component are above the container, the placement component is pulled out from between the container and the articles, and
the control unit further controls the operation of the drive unit so that the placement component is pulled out from between the container and the articles, the drive unit parallelly moves the placement component along the placement surface.

7. The article transfer device according to claim 1 , further comprising a pusher that moves along the placement surface of the first member from the second end side to the first end side.

8. The article transfer device according to claim 3 , wherein the control unit is configured such that when controlling the operation of the drive unit so that the placement component is pulled out from between the container and the articles, the first end of the first member relatively moves from proximate the side wall of the container disposed on an upstream side in the first direction to proximate the side wall of the container disposed on the downstream side in the first direction.

9. The article transfer device according to claim 3 , wherein
the placement component further includes a plate-shaped second member that has a third end, a fourth end, and the placement surface that extends between the third end and the fourth end,
the control unit being configured such that when transferring the article from the placement component to the container, the control unit controls the operation of the drive unit to change the angle formed by the placement surface of the second member and the bottom surface of the container so that the third end of the second member is disposed in a lower position than the fourth end of the second member and in the containment space positioned lower than the top of the side walls, and
the control unit is further configured such that when controlling the operation of the drive unit so that the placement component is pulled out from between the container and the articles, the third end of the second member relatively moves in a second direction opposite to the first direction in the containment space to proximate the side wall of the container disposed on a downstream side in the second direction.

10. An article transfer device that transfers a plurality of articles from a placement component to a container, the placement component including a placement surface on which plural articles are placed and then moved directly into a container, the article transfer device comprising:
a drive unit configured to relatively move the container and the placement component; and
a control unit configured to control the operation of the so that when the articles on the placement component are above the container, the placement component is pulled out from between the container and the articles,
the control unit is also configured to control the operation of the drive unit to change an angle defined between the placement surface of the placement component and a bottom surface of the container when transferring the articles from the placement component to the container, and
the control unit is configured such that when controlling the operation of the drive unit so that the placement component is pulled out from betwee
