DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrap-around caser-type packaging apparatus for storing a plurality of paper containers filled with milk, soft drinks, etc. in a container .
Especially related to an apparatus for storing and packaging products to Konapo strike with container.

[0002]

Description of the Prior Art Conventionally, a paper container containing the milk and the like, using a plastic container that has been made in only as a so-called Kayoibako is the time of delivery from the manufacturer to the dealer, ten a paper container, for example, in this container , 20 bottles packed together
Had been transported.

[0003] After the plastic container is used for delivery to a store, it is appropriately collected by a manufacturer and reused after washing. However, if the time and effort for collection and cleaning work are included, the cost for storage and maintenance becomes considerable. There is a difficulty to say. In addition, there is also a problem that it is not easy to dispose of a damaged product or a product whose service life has passed since it is made of plastic.

[0004] Therefore, a cardboard container has recently been developed as a pass-through box instead of a plastic container. This container has a structure in which a predetermined number of paper containers are collectively stored in a so-called tray shape having an open upper surface . At the time of packaging by the container, a wraparound caser for storing and packaging the paper container while assembling the container is used.

[Problems to be solved by the invention]

[0005] By the way, paper containers containing milk and soft drinks are relatively heavy, and when a predetermined number of these are packed and packaged, not only do they become quite heavy, but also these products are transported by refrigerated vehicles. Rukoto many condensation during transport moisture narrowing stain container, there may cause deformation occurs. Therefore, as a container, it has been desired to use a tray with corner posts in which the corners of the four peripheral side walls are reinforced, but the conventional wrap-around caser type packaging apparatus cannot satisfy this demand. Was.

That is, a tray with a corner post requires the flap portion located at the corner of the side wall to be folded twice, whereas a conventional wraparound caser has only a function of storing and wrapping goods accumulated on the tray or A-type cardboard. It has no flaps and cannot be folded twice. In addition, the conventional wraparound caser
The addition of a box-making machine with a tray makes the apparatus itself extremely large, and has problems such as manufacturing costs and securing installation space.

SUMMARY OF THE INVENTION The present invention has been made to meet the above-mentioned demand, and an object of the present invention is to provide a compact wraparound caser capable of storing and packaging goods accumulated in a tray with corner posts. Is to provide.

[Means for Solving the Problems]

[0008] In order to achieve the above object, the packaging apparatus of the present invention has a substantially rectangular bottom panel as a center and four sides thereof.

[0025]

The operation of the packaging apparatus according to this embodiment will be described.
First, when the sheet extracting means 4 is operated , the piston rod 20 of the air cylinder 19 is extended. Since the piston rod 20 is connected to the support member 14 and the pressing claw 16 is fixed to the rear end of the support member 14, the magazine 3 engaged with the step 18 of the claw 16
Lowermost sheet 2 is pressed <br/> press its rear end by a pressing pawl 16, flap corner posts as shown in Figure 10
It is pulled out to the folding means 5 side. The sheet 2 pulled out as described above passes through a feed rubber roll 15 and a guide roller 21 and reaches drive rollers 22 and 23 to reach the round belt 2.
6 and 26, and at this time , the corner post of the sheet 2 is
Flaps provided on part A and center side panel of flap
Hot melt H is applied to the part B from the nozzle 30 of the hot melt applying means 27 (FIG. 11).

The sheet 2 coated with the hot melt reaches the flap folding means 5 from the round belts 26, 26,
Provided on the corner post flap 2a and the central side panel
The folded piece B is folded inward. That is, when the sheet 2 as shown in FIG. 11 is conveyed by the round belts 26, 26, the cylinder 36 for supporting the vacuum box 32 is operated, and the vacuum box 32 is in the state shown in FIG.
Then , the suction members 38 and 39 come into contact with predetermined portions of the sheet 2 . Here by actuating the vacuum control device (not shown) to adsorb the suction pads 40, 41 of the suction members 38 and 39 on the back surface of the sheet 2, sheet 2
Are held as shown in FIG.

Next,For vertical movementMake cylinders 46, 46

Bull 63 descends. At this time, the end face panel is vertically raised by the folding guide 73, and in this state, descends to the lower limit position of the table 63. Here, the cylinder 75 is actuated, and the pressure plate 74 is pressed against the side panel, and the corner post flap is adhered to the inside of the side panel via the hot melt H while the flap for corner post is inserted inside the side panel. To form a drained tray. Then, when the cylinder 78 is operated and the pusher 81 is extended, as shown in FIG.
Claw 82 provided at the tip of the pusher is connected to the wife's face panel
Both the folded inwardly by pressing one of the rail, the other bars
The tray is moved to the lower surface side of the upper fixed guide plate 87 by the pusher 81 while the portion is folded inward by the folding roller 88 disposed at the tip of the beam 83. The guide plate 87 presses the tray bar downward,
The cylinder 87C is actuated, and the side flaps on both sides of the bar portion protruding outward are pressed against the side panel with the fixing plate 87a to be fixed, thereby completing the packaging as shown in FIG . Then, the tray, for which packaging has been completed, is carried out by the pusher 81.
It is discharged to the bearer side .

[0030] Note that in the description of the action has been described by dividing the operation state for each actuating member automatically the actual sequence control such as when operation is operated continuously.

The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications and design changes can be made without departing from the spirit of the invention.

[0032]

As described above, the apparatus according to the present invention has one flat surface.
And the ability to automatically box manufacturing the corner post with a tray from a plate-like sheet, since it has the function of a wrap-around packaging stuffed with goods to corner post with a tray in Seihako, corner in one machine Manufacture and trade of trays with posts
Product packaging work can be automated . Further, there is an effect that the apparatus itself is compact and the installation space is small.
