Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to treat fruits and vegetables that are particularly easily damaged.
The present invention relates to a packaging method that protects the product from impact, external pressure, etc. during transportation or loading/unloading from the time of harvest until it reaches the consumer, and also facilitates handling.

[Conventional technology]

Conventionally, fruits and vegetables have generally been packed in bulk, as disclosed in, for example, Japanese Utility Model Publications No. 10284/1984 and No. 13488/1989.

However, in this packaging, the upper part of the fruit is exposed from the pack and is not protected, so if the fruit is stacked in multiple tiers during packaging, cover the exposed upper part with cushioning material such as sheet foam net. Since the product must be covered and packed in a box, the boxing work is complicated and labor-saving cannot be achieved.

Furthermore, each fruit size class includes 20 pieces, 23 pieces, and 2 pieces.
Since we use 48 to 10 types of packs, such as 5 packs, and auxiliary materials such as cushioning material and partition sheets to cover the top of the packs, a vast amount of space is required in the boxing workshop, and the management of the various auxiliary materials is complicated. It has the disadvantage that it requires a lot of manpower to store it and transport it to the boxer's hands.

In addition, high-grade fruits are stored in a cylindrical foamed polyethylene net commonly known as a fruit cap, as shown in Figure 1.
Some products are individually wrapped, but since they do not cover the entire outer surface of the fruit, they have the same drawbacks when used in combination with the above-mentioned packs.

Furthermore, there was no packaging form that could automatically pack these soft fruits into boxes.

[Purpose of the invention]

The purpose of the present invention is to eliminate the drawbacks of conventional methods that require a wide variety of packaging materials, reduce packaging costs by creating a packaging form suitable for packaging automation, and reduce packaging costs for fruits and vegetables. To prevent bruises and abrasions even if the packaged item is rolled around or collided with it, it is protected by being completely wrapped in an anti-shock packaging material, and can be packaged in bulk in cardboard boxes, plastic containers, or returnable boxes. This was done to promote automation of the packaging process and improvement of distribution methods.

[Structure of the invention]

In order to achieve the above-mentioned object, the present invention has been developed by packaging objects such as fruits and side dishes by placing each fruit one by one into a cylindrical mesh cushioning material, that is, a rolled long cylindrical polyethylene foam net. The upper and lower sides of each item are squeezed to protect adjacent items from direct contact with each other, and a plurality of items are wrapped in a series of beads.

This cylindrical mesh cushioning material made by foaming polyethylene is a regular mesh bag that is not made of cushioning material (such as the ones sold at station kiosks that contain 5 to 6 mandarin oranges and are called Netron). It was invented with the focus on the fact that the material itself has more flexibility and can maintain its posture, making it easier to automatically package using a machine.

Hereinafter, the drawings starting from FIG. 2 showing one embodiment of the present invention will be explained.

Reference numeral 1 denotes a packaging material loading section, and 2 a roll-wound long cylindrical mesh cushioning material (foamed polyethylene net), a part of which is shown in FIG.

Reference numeral 3 denotes a packaging material supply section, which includes a drawer device 4, a welding/cutting section 5, a corner guide device 6, a length setting section 7, a feeding device 8, and the like.

Reference numeral 9 denotes a packaging device section, which includes a turntable 10, an intermittent drive device 11, a packaging material gripping device 12, an input port 13, an individual welding and sealing device 14, and the like.

15 is a packaged article supply device, and 16 is a packaged article unloading device.

The apparatus configured as described above will be explained in more detail.

A long cylindrical mesh cushioning material (foamed polyethylene net) 2 of the packaging material is loaded into a flat plate in the same manner as, for example, a fire hose is rolled up and stored, and the end of the roll is set as the tip 201 to the pull-out device 4. The retraction roller 401 is used to engulf the area (Fig. 4). The tip 201 is pulled out from the retracting roller 401 through the welding cutting section 5, passing through the pulling roller 402, and reaching the length setting section 7. When the detecting device 701 catches this, each roller 401, 402 temporarily stops, and at the same time, the welding cutting device 501 starts. Working welding iron 50
A packaging material 21 is made by welding and sealing at step 2 and cutting at cassitter 503 to have a length necessary for loading a plurality of items to be packaged.

When the packaging material 21 is completed in this manner, the rollers 401 and 402 are restarted, and the delivery roller 801 of the delivery device 8 passes the packaging material 21 through the truncated conical guide 802. On the other hand, the subsequent cut mesh cushioning material 2
is pulled out again until its tip is caught by the detection device 701, and the same operation as described above is repeated.

The packaging material 21 is transferred to the truncated conical guide 8 by the delivery roller 801.
02, the unique elasticity of the net-like cushioning material (foamed polyethylene net) works well on the truncated conical guide 802, forming a cylindrical shape, and it is sent out independently into the air, making a turn northward. The packaging material gripping device 12 provided on the table 10 is lowered.

That is, as shown in FIG. 5, the tip 121 of the packaging material gripping device 12 is small and fits into the lower part of the input port 13, and the gripping piece 122 is widened.

Once the packaging material 21 enters the packaging material gripping device 12,
A detection switch (not shown) detects this, and as shown in FIG. 6, the tapered tip 121 is widened and the gripping piece 122 grips the packaging material 21. At this time, the packaging material 21
The rear end 202 of remains within the truncated cone guide 802,
When the turntable 10 rotates, it is pulled out.

The turntable 10 of the packaging device section 9 has a plurality of packaging material gripping devices 12 and an input port 13, and is rotated intermittently by an intermittent drive device 11 for each bag packaged.

When the packaging material 21 is suspended below the input port 13 and reaches the position where the individual welding sealing device 14 and the packaged object feeding device 15 are provided, each time one packaged object 17 is fed and stored. Then, the individual welding and sealing devices 14 operate one stage at a time to form a bead-like (
After welding and sealing the product in a chain-like shape, the gripping device 12 is opened and the packaged product 18 is sent out by the packaged product delivery device 16.

In addition, when the length of the packaging material 21 is set to the length of a single piece, the packaging becomes one piece rather than a rosary (a string of beads).

Further, if the welding head 141 of the welding and sealing device 14 is made wide and a fusing wire (heating wire) or a cutting blade is provided in the center, it is possible to weld and seal each piece and also to separate them.

The packaged product whose entire periphery is sealed with the mesh cushioning material as described above is packed as is into a container such as a container, 3Fh IW+, or cardboard.

Although the present invention has been described above based on the drawings, all matters contained in the above description and the attached drawings are merely examples of the actual invention, and do not serve to limit the invention, but the scope of the claims. Other different embodiments may be used as long as the content is as described in .

〔Effect of the invention〕

The present invention can be applied to packaged items of various sizes.
Packaging is done using a long cylindrical mesh cushioning material that has stretchability and elasticity, and since it is wrapped in a single wrapping tatami material and no other auxiliary materials are required, replenishment of packaging materials, Storage management becomes extremely easy.

In addition, since the packaging material has a relatively fixed shape (ability to maintain posture), automation of packaging becomes easy, which has the effect of saving labor and greatly reducing packaging material costs and packaging costs.

Furthermore, since the entire outer periphery of the packaged item is wrapped with cushioning material, the protection performance is greatly improved compared to conventional packing or fruit camping, and it can be transported in bulk in containers or returnable boxes. This can have ripple effects, including the rationalization of distribution processes.

Furthermore, since the finished form of the packaging is a plurality of connected bodies and can be handled in units of a plurality of pieces, it is easy to handle at the retail and consumer stage 1, and there is an effect that the product will not be damaged.
