Abstract

The present invention provides a packaging bag fixing device capable of smoothly pulling out resin bags one by one with one hand before packing into a small bag. A fixing device for a plastic packaging bag (4), comprising a board (3) and two steel wire springs (1) mounted on the board (3). The packaging bag 4 is pressed from the top of the packaging bag 4 placed on the board toward the board 3. [Selection] Figure 1

Description

There is a significant tendency to wrap small quantities of various types (small mouthpieces) in plastic bags. For example, agricultural products and sweet buns. Now is the time to wrap leafy vegetables such as spinach, green onions, and eggplants in polypropylene resin (OPP film) bags. This is partly due to the fact that the bag film is strong even if it is extremely thin, has excellent transparency, and functions to make the package look beautiful.

Many agricultural products and sweet buns are packed by hand. The process includes (1) fixing the bag bundle (2) pulling out one bag from the bag bundle (3) opening the bag mouth (4) loading the package (5) closing the bag mouth, That's it.

The present invention relates to the work fields (1), (2), and (3) of the packaging work process. Both require time and improvement of efficiency is eagerly desired.

Resin packaging bags are slippery and must remain fixed. Next, the bags will be taken out one by one, but this work is also premised on the bags being properly aligned.

The first problem is fixing the bag. Bags are usually sold (distributed) in bundles of 100 sheets. The thickness of the bag film is about 20 microns. Accordingly, the thickness of the bundle of 100 sheets is around 4 mm (0.02 × 2 × 100), and this is fixed. The surface of the bag is slippery and difficult to stack, so it must be devised.

The second problem is to smoothly pull out only one sheet from a bundle of bags. In actual work, there are cases where two or more pieces are picked at a time.

The third challenge is to open the pulled bag mouth smoothly. In actual work, it is difficult to open a very thin bag, and it is often done with both hands.

The idea of claim 1 is to attach two steel wires (Fig. 1-1) connected to a spring to the board, and use the tips of the steel wires to press and fix the bundle of bags shown in Fig. 1-4 to the board. To do.

It is also effective to round the tip of the steel wire so as not to damage the bag (FIGS. 2-5 and 6) and to attach a nut-like part (FIG. 2-7) to the tip.

The spring is preferably connected to each of the two steel wires as shown in FIGS. 3-8.

Effects of the present invention

When the fixing device according to the present invention is used, it is possible to fix the packaging bag, pull out only one bag, and further perform the opening operation simultaneously with one hand.

That is, when the fixing device according to the present invention is used, as shown in FIG. 4, the surface of the bag is held with three fingers of the middle finger, the ring finger, and the little finger and moved while pressing the index finger to shift (FIG. 4-9). First, only one film on the upper surface of the bag moves and deviates from the pressing of the steel wire.

As shown in FIG. 5, this phenomenon is that the film on the lower surface of the bag is gripped by the tip of the steel wire (FIGS. 5-7), so that the bag mouth opens naturally (FIGS. 5-10). .

In this state, the package can be input, or the package may be input after all the bags are pulled out.

FIG. 1 is a perspective view of a packaging bag fixing device according to the present invention. FIG. 2 shows three examples of the tip of a steel wire spring. FIG. 3 is a top view of a steel wire spring that presses and fixes the packaging bag. FIG. 4 shows how to shift the packaging bag fixed with the left hand. FIG. 5 shows that the bag mouth has been opened as a result of shifting the surface of the bag with the index finger.

The resin bag suitable for the fixing device of the present invention is preferably a bag made of a polypropylene resin and a film called OPP. The thickness of the film is preferably 20 microns or less. As the thickness of the bag increases, its waist becomes strong (hard), and it becomes difficult to move only the surface of the bag (one film) with a finger. Most of the packaging bags for vegetables etc. that are actually distributed are less than 20 microns.

The width of the tip of the steel wire spring of the fixing device, that is, the width for pressing the bag is preferably 4 to 5 cm.

The position where the steel wire spring of the fixing device presses the packaging bag may be 1 to 2 cm from the mouth of the bag.

Wood, plastic, or metal plate can be used as the material of the board of the fixing device to which the spring is attached.

The diameter of the steel wire spring is preferably around 3 mm.

It was effective to attach a hexagon nut to the tip of the steel wire spring. (Figure 2-7)
