CONSTITUTION:Under a carrying conveyor 4 for an article to be packaged 1, a coil shaped packaging material 2' is arranged. Being cut by a cutter 3, the packaging material 2 is moved to a wrapping device 5 together with the article to be packaged 1. Standing/lying conveyor group 28, 29 stand with a roll 21 as the base point, and the surface of the article to be packaged 1, which is rectangular to the advancing direction, is wrapped such as U shape by the packaging material 2. Roll-in rolls 24, 25 are rotated with rolls 22, 23 as the base points, and the upper end of the packaging material 2 is wound on the upper surface of the article to be packaged 1, and at a joint part on the upper surface, a tape 10 is placed. While flaps 2c, 2d on the upper surface and lower surface are kept horizontal by a guide 30, a flap 2a on the advancing direction side is folded, and a flap 2b on the rear side to the advancing is folded under the guide 30 by a left flap guide 35. The flaps 2c, 2d are folded while entering upper and lower flap folding guides 40, 41, and a tape 11 is placed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an overwrapping machine for wrapping an article to be packaged, such as a carton, with a packaging material.

[Conventional technology]

As shown in Fig. 6, from the coiled packaging material 2' to the conveyor 0
After feeding the packaging material to a predetermined length in a plate shape with step 4, cutter 3
The packaging material 2 is then cut at a predetermined position and placed on standby as - sheets of packaging material 2.

When the packaged product 1 advances onto the conveyor 05, the packaging material 2 that was waiting below the conveyor 05 is fed out, and the packaged product 1 is carried onto the conveyor 05 while riding on the packaging material 2. That's how it progresses.

The process marked ■ in the figure is in this state. After that, in the step (■), as shown in the figure, the part of the packaging material 2 that wraps the surface parallel to the traveling direction of the packaged item is raised in a 0-shape, and the packaging material is overlapped and wrapped around the top surface of the packaged item 1. Afterwards, tape 1 on the top mating surface.
Paste 0.

Further advance on conveyor 06, and in step
The wrapping is folded in, the direction of travel is turned by a conveyor 07, the lower flap is folded, and a tape 11 is pasted on the side surface, resulting in a packaged product 19, which is discharged by a conveyor 08.

[Problem to be solved by the invention]

The above-mentioned conventional technology has the following problems.

In the case of conventional overwrapping, packaging can be carried out smoothly if the processing capacity is small, but it is not suitable for processing capacity of 10 pieces/min or more. The reason for this is the first
In addition, since the packaging material 2 is fed perpendicularly to the flow of the packaged product 1, it is necessary to control the movement time loss and positioning accuracy in the state box from the coiled position 1 to the standby position 2. Second
After completing step ■, fold the two bottom flaps and insert tape 1.
We are at the point where we need to change direction further in order to post a 1 (again, we need to stop the line). Tsumashi-wrapped items
Since it is necessary to make two perpendicular movements with respect to the progress of the conveyor, the stop time is long and it is difficult to increase the speed of the conveyor and to make the packaging continuous. Further, there are problems such as an increase in the size of the device.

An object of the present invention is to provide an overwrapping machine that eliminates such problems and achieves high-speed processing and compactness of the device.

[Means to solve the problem]

Match the direction of movement of the packaged product with the direction of supply of the packaging material.

Therefore, the following configuration is adopted.

1) The coiled packaging material 2' is transferred to the conveyor 4 for carrying the packaged product l.
Install it horizontally below.

2) The item to be packaged is wrapped in a 0-shape from the direction of travel (conventionally, it is wrapped from the right angle direction).

3) The upper and lower side flaps are arranged so that they can be folded along the direction of travel, so that the flaps can be folded almost continuously while the packaged product moves.

[Effect]

As shown in FIG. 1, the packaging material 2 is supplied in the same direction as the conveyance of the packaged product 1, and wrapping is performed in the traveling direction of the packaged product.

The folding member that performs wrapping is incorporated into the conveyance path.
It forms part of the transport path (conveyor) when the packaged items are moved.

The flap is folded in as the packaged product advances by a guide provided along the conveyance path of the packaged product.

〔Example〕

1 to 5, 1 is a packaged product, 2 is a sheet of packaging material, 2' is a coiled packaging material, 3 is a cutter, and 4 is a conveyor for the packaged product. 5 is a wrapping device consisting of a central fixed conveyor thorn, front and rear raised conveyor swamps, and 29 etc. 6, 7.8 are conveyors for carrying packaged products and packaging materials. 1
0 and 11 are tapes for bonding, and 19 is a packaged product.

Part 2 is the up and down conveyor road.

No. 4 rotating roll, Shio, No. 23 is the raising/lowering conveyor area, No. 29 is the driving roll. No. 25 is a winding roll attached to the tip of the raising/lowering conveyor path 29 and driven by the drive roll n, 23 via a dowel 27.

In addition, 30, 35, 40. 41 are flap guides, and rxoo is a paper feed roll.

The method of supplying the packaging material 2 will be explained with reference to FIG. 2, which shows the packaging material cutting and supplying device. A coiled packaging material is installed below the conveyor 4 for carrying the packaged items 1. The packaging material 2 cut into a predetermined length by the cutter 3 waits under the conveyor 4, and is then sent to the guide □ by the paper feed roll 100 in synchronization with the packaged product 1, and then moved to the wrapping device 5. do.

FIG. 3 shows the process of applying the wrapping device. The figure (a) shows a state in which the packaging material 2 and the packaged product 1 are stopped on the wrapping device 5. (The wrapping starts immediately from the state shown in Figure aJ, and the 4th and 29th groups of raising and lowering conveyors stand up with the roll 21 as a base point as shown in Figure bJ, wrapping the surface perpendicular to the traveling direction of the packaged product l.) Wrap the material in a U-shape. At this time, the conveyor path and the belt 29 rotate in the direction of the arrow to remove the carcass.
The packaging material 1 is tightly placed along the packaged product 1. After that, roll it up using Low/L/22.23 as the base point, and roll 2 times.
5 is rotated as shown in FIG. At this time, the winding roll 25 is rotated by the bell 27 in the direction of the arrow to tightly wind the packaging material 1. After that, the tape 10 is pasted on the mating portion of the upper surface to complete the process.

Next, the flap folding device will be explained with reference to FIGS. 4 and 5.

FIG. 4 is a plan view showing the steps of the left and right side flap folding device. (a) shows the state of the wrapped product shown in FIG. 3. After this (as shown in figure bJ), while leveling the upper and lower flaps 2c and 2d using the guide, fold in the flap 2a on the side in the direction of travel, then use the left flap guide to fold in the flap 2b on the rear side in the direction of travel. Fold it into the guide.If this state is <07 diagram, then (as shown in dJ diagram, flap 2a,
2b is folded, and the flaps on the top surface 2c and bottom surface 2d are not folded.

FIG. 5 shows the steps of the flap folding device for the upper and lower surfaces.

(a) shows a plan view, and (b) shows a side view. As shown in the diagram, flaps 2c * 2d are upper and lower flaps)
40 and 41 as it gets folded in.

(C) The figure shows a state in which the flaps are completely folded and the tape 11 is pasted. Thereafter, the flap fold 9 separates from the guide and is discharged outside the line. As described above, according to the present invention, the packaging traveling direction can be made straight.

〔Effect of the invention〕

The overwrapping packaging machine according to the present invention is divided into three parts in the traveling direction;
The front and rear devices are composed of a vertical packaging material folding/taping device, and these devices are arranged on the y-line, resulting in the following effects.
