[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a stacker that is convenient for mechanical handling of a container with a handle, which is used in a cooked rice dish manufacturing factory and a prepared food factory, which have recently been particularly mass-produced.

[0002]

[Prior art]

 In the past, empty handles could not be handled mechanically by the handles and they were handled manually. The container with a handle is used to manually put the product in after the product is put in.Since the handle is manually raised and sent to the stacker, mechanical handling is possible, but in the case of an empty container , The direction of the handle changes during washing, drying and reversing, and if it is not mechanically processed, it will be inclined and stacked as shown in Fig. 25, and if it becomes extreme, it will fall, so both the stack and the storage Unstacking became impossible, and I was forced to rely on human resources.

[0003]

[Problems to be solved by the device]

 In the present invention, the conveyor is temporarily stopped in the middle, and the handle is rotated by the rotating arm so that it can be hung down on both sides (Figs. 1 to 4). Also, when the machine is loaded as it is, the handle of the upper container rests on the lower container as shown in Fig. 24, and the handle 1 tries to rotate in both directions around its hinge 2, so the upper container is extremely unfavorable. Be stable. Therefore, as shown in FIG. 5 to FIG. 17, the stacker is provided so that the handle of the upper container is opened and placed before being stacked on the lower container so that the stacker can be stacked.

[0004]

[Means for Solving the Problems]

 For this reason, the present invention has a mechanism for hanging the handles on both sides of the empty container with handles sent from the previous step evenly on both sides, and stacking them. By stacking the upper empty containers with the handles open, the handles of the upper containers do not rest on the lower containers, but can be hung on both sides of the containers to stack, allowing a stable stack. And these are the means to solve the problems.

[0005]

[Action]

 Before stacking, pause the container on the conveyor, rotate the handle with the rotating arm to hang it down on both sides (Figs. 1 to 4), and in the stacker, lower the handle of the upper container. Stack it open before placing it in the container.
