DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. First, the phenomenon that actually occurs will be described with reference to FIG. 4. The container 2, which is a stored article, is pushed in the direction of arrow A by the extrusion device 1. At this time, the container 2 may be caught at the flap fold 3 at the opening of the completed case or semi-finished case 4 and fall. This is a completed case,
In combination with the light weight of the semi-finished case 4 and the flap fold 3, the bottom corner of the container 2 is caught and falls. The present invention has been made to eliminate such a phenomenon. Here, the details will be described based on FIG. Reference numeral 5 denotes a transport conveyor for continuously transporting a large number of containers 2, and a pair of guide members is provided on both sides of the transport conveyor 5, and a container 2 is provided between the pair of guide members at the tip of the transport conveyor 5. There are provided a plurality of guide members for aligning a plurality of guide members. A transfer plate 6 for supporting and guiding the bottom surface of the container 2 is provided in front of the transfer conveyor 5, and a stopper member 7 is disposed at a front end of the transfer plate 6, and the transfer member 5 is moved by the stopper member 7. Then, the first container 2 extruded onto the transfer plate 6 can be stopped. In front of the transfer plate 6, a bottom end portion 8 of the completed case and the semi-finished case 4 is located. The completed case and the semi-finished case 4 are guided and supplied by appropriate means. Has become. At this time, since the front end portion of the transfer plate 6 is supplied and supported by a pair of left and right guide members 9 supporting the leading end of the flap of the blank sheet of the completed case and the semi-completed case 4 in a substantially connected state, The leading container 2 extruded from the conveyor 5 onto the transfer plate 6 is placed while being pushed to the bottom of the blank sheet. The completed case and the semi-finished case 4 are sized to just accommodate the required number of containers 2 grouped together. On both sides of the front part of the conveyor 5,
A slide rail 10 is provided along the conveyor 5, and a moving frame 11 is provided on the slide rail 10 so as to freely reciprocate. The moving frame 11 is reciprocated by a driving source (not shown) via a link member.
To the moving frame 11, a container supporting member 12 which is fixed to the frontmost container 2 stopped when the moving frame 11 is at the retreat end is fixed, and in the illustrated embodiment, the frontmost container 2 is fixed. And a comb-shaped pushing member 13 to be inserted into the back surface of the container 2 in the fifth row. This pushing member 13
Is movable up and down on the moving frame 11 by the first cylinder device 14 so that the required number of containers 2 can be sandwiched between the pushing member 13 and the container supporting member 12. In this embodiment, in order to prevent the container 2 supplied on the bottom end portion 8 of the blank sheet which is the semi-finished case 4 from being caught and falling, the bottom of the blank sheet positioned on the side of the conveyor 5 is prevented. A vertical movement device 17 such as a cylinder device for vertically moving the blank sheet support member 16 is provided in front of the elevating table 15 so that the distal end portion 8 is inclined downward. Next, the top pusher 18 that pushes down the container 2 supplied onto the bottom portion of the blank sheet, which is the semi-finished case 4, is moved up and down by the second cylinder device 19. Below the top pusher 18, there is provided an elevating table 15 for supporting the bottom portion of the blank sheet.
Is lowered in response to the pressing of the container 2 by the top pusher 18 by a drive source (not shown).
In the above configuration, in the state shown in FIG. 1, the containers 2 are stopped by the stopper member 7 and the required number of containers 2 are sandwiched between the container support member 12 and the pushing member 13. At this time, a blank sheet as the semi-finished case 4 is supplied to the position shown in the figure. In this state, when the top pusher 18 is raised by the second cylinder device 19, the braking of the container 2 by the stopper member 7 provided on the top pusher 18 is released. The braking by the pushing member 13 is continued, and the container is stopped at this point. When the top pusher 18 and the stopper member 7 escape upward, the moving frame 11 is advanced at a speed higher than the transport speed of the transport conveyor 5 by a drive source (not shown) via a link member. At this time, since the front end portion of the blank sheet, which is the semi-finished case 4, is positioned by the vertical movement device 17 in a state of being inclined downward, the container 2 is smoothly caught on the flap fold portion 3 without being caught and falling. The required number of containers 2 sandwiched between the container support member 12 and the extruding member 13 are supplied onto the bottom portion of the blank sheet as the semi-finished case 4 and stopped. When this stop state is reached, the top pusher 1 is then turned on by the second cylinder device 19.
8, the container 2 is pushed down while the container 2 is held between the top pusher 18 and the elevating table 15. Thereby, the side wall portion in the front-rear direction of the blank sheet is bent upward through the guide member 9 to form a box. Thereafter, by an appropriate means, the state returns to the initial state, and the same operation is repeated thereafter. The case of the lap land caser (push-in type) has been described above. However, basically, the present invention can also be applied to the case where the container is pushed in and filled from the opening of the completed case. Further, the cylinder device is employed as a means for inclining the blank sheet of the semi-finished case, but it is also possible to convert this to a cam device or the like and employ it. FIG. 2 shows another embodiment applied to a continuous wrap round caser. The container 2 conveyed by the article conveying conveyor 21 that continuously conveys the article, for example, the container 2, is extruded by an appropriate extrusion device 1. A transfer plate 6 that supports and guides the bottom surface of the container 2 is provided in front of the article transport conveyor 21. The case 4 is conveyed by the case conveyor 22 so that the bottom end portion 8 of the case 4 is located in front of the transfer plate 6. The case 4 conveyed by the case conveying conveyor 22 supports the case 4 by raising and lowering the case guide 20 which is previously inclined so as to have a height difference, and lowering the case 4 insertion side as shown in the figure. It was made possible. In addition, in the embodiment shown in FIG. 3, in the embodiment shown in FIG. 2, instead of the inclined case guide 20, the third cylinder device 23 can be moved up and down so that an appropriate height difference is provided. Things. The other parts are the same as those of the embodiment shown in FIG. Needless to say, the height difference of the case guide 20 may be provided only when the first container 2 is transferred to the case 4. Needless to say, the means for filling the container into the case is synchronized with the continuous type and the intermittent type so that the case is tilted.
