  The conventional article receiving device requires a dedicated actuator such as an electric motor type lifting device or a lifting device using a fluid pressure cylinder in order to move the article receiving tool back and forth, and the configuration of the article receiving device is complicated. There was a disadvantage incurring high costs.

  In addition, the conventional article processing facility includes an article receiving device that has a complicated configuration and high cost, and thus has a disadvantage in that the configuration of the entire article processing facility is complicated and expensive.

  The article processing equipment provided with the article receiving device is not limited to the stacking process or the spreading process described in the cited document 1, but, for example, the article is placed and transported by a transport conveyor. Processing to raise the article stopped by the receiving device and branch to a different conveying path intersecting the conveying path of the conveying conveyor, or to lift the article that has been placed and conveyed by the conveying conveyor and stopped by the article receiving device There is an article processing facility that performs various processes such as a process of turning the article and changing the posture of the article in the conveyance direction.

  An object of the present invention is to provide an article receiving apparatus capable of reducing the cost by simplifying the configuration.

  Another object of the present invention is to simplify the configuration by using an article receiving apparatus having a simple configuration, and to effectively use the apparatus configuration originally provided. The present invention is to provide an article processing facility that can switch the position of the item.

The article receiving apparatus according to the present invention protrudes above the conveying action surface of the conveying conveyor for placing and conveying the article and is located below the conveying action face and the article stopping action position where movement on the lower side in the conveying direction is restricted. An article receiving tool whose position is freely changeable is provided at an article passage allowable position to be retired, and the first characteristic configuration thereof is:
The article receiving tool is supported at a receiving standby position that protrudes above the conveying action surface on the upper side in the conveying direction than the article stopping action position so as to be freely changeable in position.
The article receiving tool is urged to return to the receiving standby position so as to return to the receiving standby position from the article stopping operation position and to return to the receiving standby position from the article passage allowable position. Biasing means are provided ,
The article receiver is
By swinging from the receiving standby position to the lower side in the conveying direction, the position is changed to the article stopping action position, and by swinging from the receiving standby position to the upper side in the conveying direction, it is retracted below the conveying action surface. Then, in a state where the position is changed to the article passage allowable position, is supported so as to be swingable around a horizontal axis that is located below the transfer action surface of the transfer conveyor,
The pressed portion on the upper end side of the article receiving tool is pushed downward by the article so as to swing from the receiving standby position toward the upper side in the conveying direction and change the position to the article passage allowable position. Further, it is configured to protrude toward the upper side in the transport direction than the horizontal axis at the receiving standby position,
A contact restricting body is provided that restricts the swing of the article receiving tool at the article stop operating position toward the lower side in the conveying direction .

  According to the first characteristic configuration, the article receiving tool configured to be freely changeable in the article stopping action position and the article passage allowing position is closer to the conveyance action surface than the article stopping action position on the upper side in the conveyance direction. Also, it is configured to be supported at a receiving standby position protruding upward so that its position can be freely changed. Then, the article receiving tool is moved back by the biasing means from the article stopping action position to the receiving standby position and from the article passage allowable position to the receiving standby position. Return to the receiving standby position is urged.

  That is, if the article receiving tool is in a free state where no external force is applied from the outside, the article receiving tool is positioned at the receiving standby position by the biasing force of the biasing means, and is positioned at the receiving standby position. Thus, it waits for an article to be conveyed. And when the article is placed and conveyed by the conveyor, the article contacts the article receiver located at the receiving standby position and is pressed toward the lower side in the conveying direction by the conveying force of the conveyor. The article receiver moves to the lower side in the conveying direction against the urging force of the urging means. When the article receiving tool moves to the article stopping action position, movement on the lower side in the transport direction is restricted, and the article is received and stopped.

  The article received and stopped by the article receiving tool in this way is lifted upward by another operation, for example, by an operation using an elevating-type article support means or a manual operation. Since the article receiving tool has no pressing action on the article, it is returned to the receiving standby position by the urging force of the urging means.

  For example, when the article is lifted upward and another process is performed and then the article returns onto the conveyor, the article catcher positioned at the receipt standby position is directed from the upper side to the lower side. When the article is lowered so as to be pressed, the article receiving tool moves downwardly against the urging force of the urging means and moves to the article passage allowable position. While the article is positioned on the upper side of the article receiver, the article receiver is maintained in the article passage allowable position. Articles can be transported by a transport conveyor. When the article is conveyed and the article is not pressed against the article receiving tool, the article receiving tool returns to the receiving standby position by the urging force of the urging means.

  Since the urging means can be constituted by a member having a simple structure such as a spring or rubber, for example, a dedicated actuator such as an electric motor type lifting device or a lifting device using a fluid pressure cylinder is used. It is possible to cope with a simple configuration without providing the.

  Therefore, it has become possible to provide an article receiving apparatus that can be switched between the article stopping action position and the article passage allowable position, but can be reduced in cost by simplifying the arrangement.

Further , according to the first characteristic configuration, the horizontal axis core positioned below the transfer action surface of the transfer conveyor in a state in which the article receiving tool is urged back to the receiving standby position by the urging means. It is supported so that it can swing around. Then, in the state of being biased back to the receiving standby position, for example, when pressed by an article conveyed by a conveying conveyor, the article receiving tool swings around the horizontal axis and the receiving By swinging from the stop standby position to the lower side in the conveying direction, the position is changed to the article stop operating position. At this time, since the contact restricting body restricts the swing of the article receiving tool toward the lower side in the transport direction, the article receiving tool stops at the article stopping action position, and the article is It will be received and stopped by the article receiver.

  Further, when the pressed portion on the upper end side of the article receiving tool is pressed downward by the article in the state of being biased back to the receiving standby position, the article receiving tool is moved to the receiving standby state. By swinging from the position toward the upper side in the conveying direction, the position is changed to the article passage allowable position. That is, since the pressed portion on the upper end side of the article receiving tool is configured to protrude to the upper side in the transport direction from the horizontal axis core at the receiving standby position, the pressed portion is below the article. When it is pressed to the side, a component force that causes the article receiver to swing toward the upper side in the conveying direction is generated by the downward pressing force, so that the article receiver is pressed downward by the article. It is possible to change the position to the article passage allowable position by swinging toward the upper side in the conveying direction only by the action.

  Therefore, since the article receiving tool is configured to swingably support around the horizontal axis, the position of the article receiving tool is changed between the receiving standby position and the article passage allowable position, and A support structure for allowing a change in position between the receiving standby position and the article stopping action position can be simplified.

  For example, the article receiving tool is supported so as to be slidable in the vertical direction so that the position of the article receiving tool can be changed between the receiving standby position and the article passage allowable position. The position can be changed so as to be slidable in the horizontal direction so that the position of the article can be changed freely. However, in such a configuration, the slidably supported in the vertical direction is supported. A plurality of support structures, ie, a support structure for supporting slidable movement in the horizontal direction, and a structure for supporting the article catcher is complicated, but compared to such a structure. If the configuration is such that the article receiver is supported so as to be swingable around the horizontal axis, the support structure can be simplified, and the configuration of the urging means can be simplified.

Therefore, according to the first feature structure, the structure of the article receiver can be simplified and the cost of the article receiver can be further reduced by simplifying the structure of the support structure and the biasing means. A stop device can be provided.
