Description

[Detailed description of the invention] (Industrial Icheon field) The present invention relates to a packaging device for agricultural products.

(Conventional technology and problems to be solved) Among agricultural products, especially vegetables, it is important to provide products with good freshness. Therefore, measures are taken to maintain freshness as much as possible at the production area and provide it to the market. There is. for example,
In the case of spinach, the freshness decreases when water evaporates, so it is packed in bags to prevent water from evaporating, or after being packed into bags, it is pre-cooled before being transported to the point of consumption.

However, when the vegetables are packaged in bags, the moisture released from the vegetables can cause the bags to fog up, so it is recommended to use bags that have been treated to prevent fogging, to make holes in the bags to make pre-cooling easier, or to use differential pressure pre-cooling. Must be.

There are some problems when using bags in this way, so instead of using bags, a method of wrapping vegetables in a cylinder shape with a sheet has come to be used.

According to this method, since the top and bottom of the package are open, there is no need for an air-permeable interlayer during pre-cooling, or an interlayer that could cause vegetables to rot due to water accumulated inside the bag during bagging. There are advantages.

In the past, when wrapping vegetables into a tube shape as described above, the process was mostly done by hand, and there is currently no packaging device that is easy to handle. Therefore, the present invention was made to solve the above-mentioned problems. The purpose of this product is to provide vegetable packaging that can be easily rolled into a cylinder shape with a packaging sheet and that can be wrapped suitably for packaging various vegetables including spinach. The aim is to provide equipment.

(Means for solving problems) The present invention has the following configuration to achieve the above object.

That is, a roll mounting section on which a roll around which a packaging sheet is wound is mounted is arranged in front of the roll with a space between the roll and the roll for placing an object to be packaged on the packaging sheet, and the roll is unwound from the roll. A pair of rollers clamps and supports the front end of the wrapped packaging sheet, moves back and forth between the lower part of the rolls and the rollers at approximately the same height as the rollers, and is pulled out between the rollers and the roller mounting section and pushed downward. A loop-shaped part of the wrapping sheet is formed by pressing and moving the packaging sheet placed on the hanging intercolor sheet in the direction of the roller between the packaging sheet and the roller attachment part. an insert plate that wraps the packaging sheet and pushes the overlapping part of the packaging sheet between a pair of rollers; a cutter that is provided on the underside of the insert plate and moves back and forth with the insert plate to cut the packaging sheet in the width direction during packaging; A special function characterized by having a welding part that moves reciprocatingly and welds the overlapping part of the packaging sheet on the inside of the packaged object side from the cutting line position of the cutter during packaging.The packaged product is fed out from the roll. The packaging sheet is placed on the hanging packaging sheet between the rollers, and as the insert plate presses and moves the packaging sheet in the direction of the rollers, it is wrapped in the loop formed between the front edge of the insert plate and the roller. . When the front edge of the insertion plate enters between the rollers, the overlapping packaging sheets on the side of the packaged object are welded together by the welding section, and the packaging sheet is cut by the cutter to package the packaged item into a cylinder. Example) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is an explanatory view showing an embodiment of a packaging device according to the present invention, showing a main part of the packaging device viewed from the side.

The object to be packaged is packaged using a long packaging sheet 10, and the packaging plate 10 is formed to have a predetermined width depending on the size of the object to be packaged, and is provided as a roll 12. roll 12
is set in a roll mounting section whose rotation and stop are controlled according to the amount of the packaging sheet fed out.

Reference numeral 14 denotes a pair of rollers installed horizontally in the width direction (perpendicular to the paper surface) at a front position facing the roll 12. The roller 14 is a packaging sheet IO fed out from the roll 12.
The front end portion of the packaging sheet 10 is pressed and supported vertically, and the direction of rotation is a direction in which the packaging sheet 10 is sent only forward. Rotation and stop are controlled according to the packaging operation of the packaged part.

The object to be packaged 16 is placed on the packaging sheet 10 unrolled from the roll 12 and packaged. Therefore, the roll 12 and the roller 14 are arranged with a space for placing the object to be packaged 16 thereon.

18 is located below the roll 12 before the start of packaging,
It is an insertion plate installed at the same height as the packaging sheet pinching position of the 0-ra 14, 20 is a cutter fixed to the lower surface of the insertion plate 18, and 22 is a welded part fixed to the lower surface of the cutter 20. be.

The insertion plate 18 is formed as a thin plate-like body, and is formed to have the same width as the packaging sheet 10 or a little wider. The cutter 20 has a horizontal blade for cutting the packaging sheet IO in the width direction, and is provided at a position slightly set back from the front edge of the insertion plate 18.

The welding part 22 is for welding the overlapping packaging sheets 10 in the width direction when the packaged item 16 is covered with the packaging sheet 10.
A heater for welding is installed inside.

Although the welded portion 22 is provided at a position farther back than the blade of the cutter 20, the blade of the cutter 20 and the welded portion 22 are provided as close as possible to reduce the uncut portion of the packaging sheet 10.

The insertion plate 18 presses and moves the packaging sheet 10 that has been unwound from the roll 12 toward the roller 14 side, and the pair of rollers 1
It is inserted between the rollers 14 and the packaging sheet IO, and is supported by a drive body that reciprocates horizontally, and the position between the lower position of the roll 12 and the position where the packaging sheet 10 is inserted between the rollers 14 is 1 to reciprocate.
