Technical Field

The present invention relates to a method for manufacturing a filter molded product using a laser processing technique.

Background

So-called tea bags, in which an extraction liquid can be easily obtained simply by sealing a raw material such as tea, coffee, or soup in an extraction filter and extracting the same in hot water, are mostly rectangular or triangular pyramid-shaped from the viewpoints of ease of molding and extraction efficiency.

On the other hand, patent document 1 discloses a heart-shaped, star-shaped, fruit-like, or animal-like shaped tea bag as a filter molded product having a peculiar shape.

Patent document 1 discloses a method of manufacturing such a filter molded product having a peculiar shape, in which a filter is sandwiched between a base and a mold, and the filter is cut and welded in a predetermined shape by using a fusion cutting tool that emits ultrasonic waves.

However, the method described in patent document 1 has not been automated yet, and has a problem that it needs to be performed manually, and the manufacturing efficiency is poor.

Further, in the contact type tool such as the fusion cutting tool described in patent document 1, there is a problem that the overlapping of the filters is deviated or scattered, and it is difficult to simultaneously perform cutting and welding in a desired accurate shape.

Further, the mold is expensive, and if the mold is prepared for each shape, a high cost is required.

In addition, in ultrasonic welding, if the filter is in a straight and simple shape as in a conventional filter molded product such as a tea bag, welding can be performed while cutting the filter, but it is known that sufficient welding and cutting cannot be performed for a complicated shape such as a heart-shaped curve or a star-shaped tip portion, which causes content loss. Further, since the welding cannot be performed neatly and accurately, the shape is defective.

Patent document 2 describes the following method: as a method for producing a filter molded product having a peculiar shape, a filter is cut into a predetermined outer shape in advance, and two pieces of the filter are overlapped and sewn at a predetermined pitch to such an extent that tea leaves do not flow out.

However, if the filter is sewn with only thread as in the method described in patent document 2, the thread is loosened with time, and thus there is no problem in individual manufacture and use, but it is not suitable for mass production.

Further, if the filter is cut in advance into a predetermined outer shape, there is a problem that additional labor and cost are required.

Disclosure of Invention

Problems to be solved by the invention

The present inventors focused on the laser processing technology to establish a method for producing a filter molded article, which has higher production efficiency or reduced production cost than conventional methods and can be easily produced even when the filter has a peculiar shape.

On the other hand, when a powdery raw material is sealed in a filter molded product such as a tea bag, it is difficult to manufacture the filter molded product by using only a laser processing technique.

In order to cut the filter neatly, it is necessary to focus the laser light, but when focusing, the filter is not welded smoothly, and a gap is left. Since this gap causes the contents of the tea bag to flow out during transportation and use, it is necessary to completely eliminate the non-welded portion.

On the other hand, it is known that if the focal point is widened, welding can be performed without a gap, but cutting cannot be performed neatly, resulting in deformation.

In view of such a new problem, a second object of the present invention is to provide a method for producing a filter molded article in which the outflow of the content is suppressed while the production efficiency is high or the production cost is suppressed by using a laser processing technique, and a filter molded article in which the outflow of the content is suppressed.

Detailed Description

Hereinafter, a filter molded product and a method for manufacturing the filter molded product according to an embodiment of the present invention will be described in detail, but the present invention is not limited thereto.

(1) Filter formed product

In the present specification, the filter molded product is a generic term for a product obtained by processing and molding a filter.

Examples of the filter molded product include a filter cut into a specific shape, an extraction filter such as a tea bag, and a hook label (フックタグ).

In the conventional method for manufacturing a filter molded product according to the present invention, the extraction filter portion and the label portion can be manufactured using the same material and the same production line, and thus the manufacturing process can be simplified and the cost can be reduced.

The material of the filter used in the filter molded product of the present invention is not particularly limited as long as it is a filter capable of extracting the components of the enclosed raw material using a liquid such as hot water or water, and is preferably one selected from paper, nonwoven fabric, nylon yarn, polyester yarn, and biodegradable fibers of plant origin.

According to the embodiment of the present invention, a filter molded product using a filter made of a plurality of materials may be used.

In the case of manufacturing an extraction filter such as a tea bag as a filter molded product, the space between the filter and the filter may or may not contain a raw material.

Here, the raw material in the present specification means a substance that exerts an effect by being put into a filter, and examples thereof include: ingredients contained in raw materials for dissolution or extraction such as tea leaves, coffee, chinese medicines, soy sauce soup, sports drinks, and soup, ingredients contained in miscellaneous goods such as aromatic materials and mixed spices, and ingredients used in stones, ores, deodorants, and deodorants, etc., which have hot spring effects when put in a bath.

The extraction filter containing no raw material can enclose a raw material that the user likes.

(2) Method for manufacturing filter molded product

The method for manufacturing a filter molded product of the present invention includes a cutting step of cutting a filter using a laser.

According to the present invention, the filter can be cut into specific different shapes by effectively utilizing the precision operability of the laser.

The present invention is suitable for the production of the following assembled filter molded product.

In addition, the present invention also provides a method for manufacturing a filter molded product, which includes a cutting and welding step of overlapping two or more filters and cutting and welding the two or more filters using a laser.

According to the present invention, the filter molded article can be welded to a degree that can be manufactured without any problem as long as the filter molded article is a filter molded article in which the two or more filters are cut in order and does not contain a raw material, or a filter molded article in which a raw material such as stone, ore, or the like having a hot spring effect is sealed so large that the raw material does not flow out from a gap.

Further, according to the present invention, the filter molded product can be manufactured with higher manufacturing efficiency than the conventional method for manufacturing the filter molded product, and a mold corresponding to the shape of the filter molded product is not required, so that the filter molded product can be manufactured at low cost.

As the laser used in the method for producing a filter molded article of the present invention, a solid laser and a gas laser generally used for machining and welding can be used, and CO is preferably used₂And (4) laser.

The upper limit and the lower limit of the laser output are different depending on the kind of the filter, and can be appropriately adjusted by those skilled in the art.

For example, when the filter is a nonwoven fabric, the lower limit of the output of the laser is preferably 10W or more, more preferably 15W or more, and particularly preferably 20W or more. The upper limit of the output of the laser beam is preferably 150W or less, more preferably 140W or less, and still more preferably 130W or less.

The number of sheets of the overlapped filter is not particularly limited, and can be appropriately changed according to the required strength.

When the filter molded product is an extraction filter, the number of stacked filters is preferably 10 or less, more preferably 8, and even more preferably 6 or less, from the viewpoint of extraction efficiency.

When three or more filters are stacked to produce an extraction filter, it is preferable that the raw material be sealed in the outermost filter and the next filter.

By adopting such a form, it is possible to suppress a decrease in extraction efficiency due to overlapping of a plurality of filters.

In one embodiment of the present invention, the method further comprises a reinforcing step of sewing, welding or heat-welding the two or more filters after the cutting and welding step.

By having the reinforcement step, a filter molded product in which the outflow of fine raw materials such as tea leaves and coffee powder is suppressed can be manufactured.

In addition, even when the reinforcing step is provided, the cutting and welding step is provided by using a laser, so that the manufacturing efficiency is remarkably improved as compared with the conventional method for manufacturing a filter molded product, and a mold corresponding to the shape of the filter molded product is not required, whereby the filter molded product can be manufactured at low cost.

The stitching may be performed by hand stitching or by a sewing machine. From the viewpoint of manufacturing efficiency, the sewing is preferably performed by a sewing machine programmable to sew into a predetermined shape.

The method of thermal welding is not particularly limited, and ultrasonic welding, hot air welding, hot plate welding, impulse welding, soldering welding, and the like can be used.

In the case of performing the thermal welding, the temperature of the applied heat varies depending on the kind of the filter, but may be appropriately changed and adjusted by those skilled in the art.

For example, if the filter is a nonwoven fabric, welding can be performed by applying heat of 140 ℃ to 240 ℃.

Preferably, the welding is performed by applying heat of 160 ℃ to 200 ℃. By applying heat in such a temperature range, welding can be performed more neatly.

Further, as the ultrasonic welding, a device generally used for welding of a filter can be used, and examples thereof include a sealer type device, a pen type device, a programmable ultrasonic pen, an ultrasonic sewing machine, and the like.

In the method for producing a filter molded article according to the present invention, when producing a filter molded article in which a raw material is sealed, the raw material may be sandwiched between the filter and the filter in advance before the cutting and welding step, or the raw material may be charged from a non-welded portion after the cutting and welding step and then the reinforcing step may be performed to seal the raw material.

Further, according to the present invention, the user can manufacture a filter molded product having a raw material inlet into which a desired raw material can be put.
