Description

  The present invention can be applied to biopaste sheets such as poultices, cosmetics, quasi-drugs, electrode materials, industrial sheets such as vibration proofing, logistics, building materials, automatic chapter parts, PDPs (plasma display panels), touch panels, etc. The present invention relates to an oil supply device for a gel sheet cutting blade that cuts or halves a long gel sheet used as a spacer or the like of an optical member, and a gel sheet manufacturing apparatus including the oil supply device.

  If the gel sheet is stored as it is, it is difficult to secure a storage place and mass production is difficult. Therefore, an adhesive gel is sandwiched between protective films, wound into a roll, stored and managed. And when it commercializes, it pulls out from a roll, The long gel sheet is punched out to the magnitude | size and shape based on the goods requested | required, and the desired gel sheet is manufactured.

However, the gel constituting the gel sheet is sticky, and adhesion of the gel to the cutting blade becomes a problem in the work process of continuously cutting the gel sheet.
Therefore, in order to solve this problem, a technique of applying oil such as silicone oil to the cutting blade is used. As an example, there is a method of spraying and adhering silicone oil to the cutting blade. Although it is not a gel sheet cutting blade, for example, Japanese Patent Application Laid-Open No. 2005-153116 (Patent Document 1) discloses a technique of spraying and applying cutting oil to a trimmer blade in a side trimmer device that shears an edge portion of a steel plate. Yes.

JP 2005-153116 A

However, in the spraying method, the droplets are non-uniform and coating unevenness occurs. In addition, there is a problem that the working environment is deteriorated or the application efficiency is deteriorated due to the oil flying in the air.
Therefore, in view of such a problem, the present invention has been made for the purpose of making it difficult to cause deterioration of work efficiency due to adhesion of a gel, deterioration of the degree of cutting, and the like even when a gel sheet is continuously cut.

In order to achieve the above object, the following invention is provided.
That is, a gel sheet cutting device having a cut roll on which a gel sheet cutting blade is arranged and capable of cutting or semi-cutting a long gel sheet, and supplying oil to the cutting blade to prevent the gel from adhering to the cutting blade An oil supply device comprising: an oil supply device that receives an application oil from an oil pan in which the application oil is stored, and an application oil from the supply roll and transfers the applied oil to a cut roll A transfer roll; a supply roll; and a coating roll support for supporting the transfer roll, the surface of the transfer roll being formed of an elastic porous material capable of covering the surface of the cutting blade, and coating This is a gel sheet manufacturing apparatus in which the roll support tool supports the supply roll and the transfer roll so as to be horizontally movable, and the amount of oil applied to the cutting blade can be adjusted.

  An oil supply device that contacts a cut roll provided with a gel sheet cutting blade capable of cutting or semi-pulling a long gel sheet, and supplying the coating oil to the cutting blade to prevent the gel from adhering to the roll. A supply roll that adsorbs coating oil from an oil pan in which oil is stored, a transfer roll that receives the coating oil from the supply roll and transfers it to a cut roll, and a coating roll support that supports the supply roll and the transfer roll The surface of the transfer roll is formed of an elastic porous material capable of covering the surface of the cutting blade, and the roll support for application supports the supply roll and the transfer roll so as to move horizontally, and the cutting This is an oil supply device that can adjust the amount of oil applied to the blade.

  The gel sheet manufacturing apparatus includes a gel sheet cutting apparatus having a cut roll on which a gel sheet cutting blade is disposed and capable of cutting or semi-cutting a long gel sheet, and supplying a coating oil to the cutting blade to attach the gel to the cutting blade. Therefore, the oil applied to the cutting blade of the gel sheet cutting device can be applied to the cutting blade of the gel sheet cutting device, and the cutting force of the cutting blade can be maintained even in the continuous production of the gel sheet.

  The oil supply device includes a supply roll that adsorbs the application oil from an oil pan that stores the application oil, a transfer roll that receives the application oil from the supply roll and transfers it to the cut roll, and a coating roll that supports the supply roll and the transfer roll. Since it comprised as what comprises a roll support tool, application | coating oil can be apply | coated to a cutting blade directly from a transfer roll. Therefore, compared with the case of application | coating by spraying etc., the scattering to the environment of application oil and the bad influence with respect to a body can be reduced.

Further, the surface of the transfer roll is formed of an elastic porous material capable of covering the surface of the cutting blade, and the coating roll support tool supports the supply roll and the transfer roll so as to move horizontally, and the cutting blade Since the amount of coating oil to be applied to can be adjusted, the amount of coating oil applied can be appropriately adjusted according to changes in the size and shape of the cutting blade.
In other words, because the surface of the transfer roll is made of an elastic porous material that can cover the surface of the cutting blade, it can be used with various cutting blades that can have various sizes and shapes corresponding to the required products. The coating oil can be applied to the surfaces of the various cutting blades.
And since the roll support tool for application supports the supply roll and the transfer roll so that they can move horizontally, it is possible to apply an appropriate amount of application oil according to various cutting blades.

  The surface of the supply roll can be formed of a porous material that can adsorb coating oil. Since the surface of the supply roll is made of a porous material that can adsorb coating oil, a sufficient amount of coating oil can be adsorbed from the oil pan. Further, if the material of the supply roll is a porous material made of the same material as that of the transfer roll, the transfer of the coating oil from the supply roll to the transfer roll can be easily performed.

The porous material forming the surface of the supply roll, the surface of the transfer roll, or both of the rolls may have continuous pores and a water retention rate of 250% to 450%.
Since the porous material has continuous pores and a water retention rate of 250% to 450%, a sufficient amount of coating oil can be held on the supply roll and the transfer roll. For this reason, it is possible to prevent the coating blade from being insufficiently applied to cutting blades that can have various sizes and shapes.

The coating roll support has a groove that opens in the horizontal direction for taking in the axes of the supply roll and the transfer roll, and the axes of the supply roll and the transfer roll are movable in the horizontal direction in the groove.
Since the coating roll support has a concave groove opened in the horizontal direction for taking in each axis of the supply roll and the transfer roll, each axis of the supply roll and the transfer roll inserted into the concave groove may move in the horizontal direction. Yes, it cannot move in the vertical direction because it is blocked by the groove wall.
Since the supply roll and the transfer roll can be moved independently in the horizontal direction, the gap between the rolls and the pressure between the rolls can be adjusted. Can be adjusted. Accordingly, it is possible to supply an amount of coating oil corresponding to the size and shape of the cutting blade.

  The contact point between the transfer roll and the cut roll can be provided above the center of the cut roll. Since the contact point between the transfer roll and the cut roll is provided above the center of the cut roll, the required amount can be reliably applied when applying the coating oil from the transfer roll to the cutting blade of the cut roll.

  According to the gel sheet manufacturing apparatus or the oil supply apparatus of the present invention, the coating oil can be suitably applied to the cutting blade for cutting or half-cutting the gel sheet, and the gel does not easily adhere to the cutting blade, and continuous operation is possible. It is.

It is a right view of the oil supply apparatus to a gel sheet cutting blade. It is a top view of the oil supply apparatus to the gel sheet cutting blade of FIG. It is explanatory drawing explaining attachment of the roll to the roll support tool for application. It is a top view of a transfer roll. FIG. 3 is a plan view corresponding to FIG. 2 in a state where an oil supply device is pulled out.

Specific embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a right side view of the gel sheet manufacturing apparatus 1, and FIG.
The gel sheet cutting device 1 cuts the gel sheet 3 into a desired size and shape required as a product from the long gel sheet 2 used as a roll, for example, in the manufacture of a gel sheet used for a poultice etc. It is a device to obtain.
This gel sheet manufacturing apparatus 1 supplies gel oil to the cutting blade 11 by supplying silicone oil or the like to the cutting blade 11 of the gel sheet cutting apparatus 10 for cutting or half-cutting the long gel sheet 2 and the gel sheet cutting apparatus 10. An oil supply device 20 to the gel sheet cutting blade 11 to be prevented is provided.

The gel sheet cutting apparatus 10 includes a cut roll 12 having a gel sheet cutting blade 11 and a pressing roll 13 that presses the long gel sheet 2 against the cut roll 12.
In addition, the oil supply device 20 receives the application oil 21 from the supply roll 23 that supplies the application oil 21 from the oil pan 22 that stores the application oil 21 such as silicone oil, and the application oil 21 to the cut roll 12. And a coating roll support 25 that supports the supply roll 23 and the transfer roll 24 so as to be independently movable in the horizontal direction. The supply roll 23 and the transfer roll 24 are collectively referred to as a coating roll 26.

The gel sheet cutting blade 11 is provided on the cut roll 12, and is formed in a shape along the size and shape of the gel sheet 3 to be cut out. In FIG. 2, the cutting edge is formed in a rectangular shape, and two rectangular gel sheets 3 are formed in the width direction of the original fabric.
Although the gel sheet cutting blade 11 depends on the configuration of the long gel sheet 2, it usually has a surface protective film and a gel for protecting the surface of the long gel sheet 2, and a core inside the gel for supporting the shape of the gel. A material that has a cutting force for cutting or half-cutting the material and hardly adheres to the gel is used. Specifically, a cutting blade 11 made of metal or hard resin can be used, but a steel material such as SKH (high speed tool steel) is preferable.

The oil supply device 20 is a device that applies coating oil 21 for preventing adhesion of gel typified by silicone oil or the like to the cutting blade 11 to the cutting blade 11 through a coating roll 26. The supply roll 23 adsorbs the coating oil 21 stored in the oil pan 22 and transfers it to the transfer roll 24, and the transfer roll 24 contacts the cutting blade 11 to apply the coating oil 11 on the surface of the cutting blade 11.
By applying the coating oil 21 to the cutting blade 11, it becomes difficult for the adhesive gel to adhere to the cutting blade 11. In addition, there is an advantage that the product part and the unnecessary part are easily peeled off after cutting.

  The transfer roll 24 is required to have elasticity and water retention capable of covering the surface of the cutting blade 11 so that the coating oil 21 can be evenly applied to the surface of the cutting blade 11 and not excessively applied. Therefore, a porous sponge-like material is used. In particular, a porous material having continuous pores having a porosity of 75% to 90% and a water retention rate of 250% to 450% is preferable. In addition, urethane sponge is a preferable material because it is brittle and it is required that the roll material does not fall off.

  The supply roll 23 is a roll that receives the coating oil 21 from the oil pan 22 and can be a plastic roll such as a rubber roll or urethane. However, a material that does not repel the coating oil 21 is preferable. For example, silicone oil is applied to the coating oil 21. When using, the roll made from a silicone resin can be illustrated. Further, a concave groove may be formed on the surface of the supply roll, and the coating oil 21 may be transferred to the transfer roll 24 through the concave groove. However, a roll having the same material surface as the transfer roll 24 may be used. This is a preferred embodiment. This is because the degree of wetting is the same if the material is the same, and it is easy to transfer without staying on the supply roll 23, and a sufficient amount of coating oil 21 can be retained if it is a porous material.

  The radius of the supply roll 23 is preferably smaller than the radius of the transfer roll 24. By reducing the radius of the supply roll 23 and increasing the number of rotations, it is possible to increase the chance of contact with the application oil 21 in the oil pan 22 and to sufficiently spread the application oil 21 on the surface of the supply roll 23. is there. As shown in FIG. 2, the width of the transfer roll 24 is preferably larger than the width of the supply roll 23. When the transfer roll 24 hits the cutting blade 11, the portion hit by the cutting blade 11 is recessed. This is because the extent to which the cutting blade 11 protrudes and the volume thereof can vary depending on the product, so that it is necessary to have a margin enough to hold the coating oil 21 even when the amount of dent increases.

The arrangement of the transfer roll 24 and the cut roll 12 is preferably in contact with the transfer roll 24 at a position above the center of the cut roll 12. Considering the case of supplying a general printing ink different from the coating oil 21, the printing ink reflected on the transfer roll 24 from the supply roll 23 can be immediately transferred to the cut roll 12 side in order to prevent the influence of drying of the printing ink. Less movement of the printing ink on the transfer roll 24 is preferable. Therefore, it is preferable to contact the cut roll 12 at a position above the center of the transfer roll 24. When viewed from the cut roll 12 side, it is preferable to contact the transfer roll 24 at a position below the center of the cut roll 12.
However, when the coating oil 21 is applied, the coating oil 21 does not have to be a problem so much that the coating oil 21 itself is dried, and the coating oil 21 is downward in order to sufficiently wet the surface of the cutting blade 11 having a large surface area. This is because a sufficient amount of coating oil 21 can be applied when transferred, and overcoating can also be prevented.

  A right side view of the bracket 27 constituting the coating roll support 25 is shown in FIG. The bracket 27 is a member that supports the supply roll 23 and the transfer roll 24, and is formed with concave grooves 27a and 27b into which the shafts 23a and 24a of the supply roll 23 and the transfer roll 24 are inserted. The concave grooves 27a and 27b are provided with screw holes at the bottoms of the concave grooves 27a and 27b so that the screws 28a and 28b can be inserted from the outside.

On the other hand, the transfer roll 24 is provided with a screw groove 24b as shown in FIG. 4, and the shaft 24a of the transfer roll 24 is inserted into the concave groove 27b of the bracket 27, and the screw 28b is inserted into the screw groove 24b. Thus, the transfer roll 24 can be fixed in the concave groove 27b. Therefore, the shaft 24a of the transfer roll 24 can be moved in the horizontal direction in the concave groove 27b by turning the screw 28b.
As shown in FIG. 2, since the bracket 27 is provided on both sides of the transfer roll 24, the position of the shaft 24a protruding to the right and the shaft 24a protruding to the left from the center of the transfer roll 24 can be adjusted independently. it can.

A roll body 24d having a porous material on its surface is connected to the shaft 24a of the transfer roll 24 through a bearing 24c. Thus, the roll body 24d is rotatable with respect to the fixed shaft 24a.
Similarly to the transfer roll 24, the supply roll 23 has a structure including a shaft 23a, a screw groove 23b, a bearing 23c, and a roll body 23d. The supply roll 23 is attached to the concave groove 27a provided in the bracket 27, and is adjusted by adjusting the screw 28a. 27a can be moved horizontally.

  Thus, since the transfer roll 24 and the supply roll 23 can be moved back and forth in the horizontal direction with the screws 28b, 28a, the intervals between the rolls of the supply roll 23, the transfer roll 24, and the cut roll 12, The contact pressure can be changed. And the quantity of the application oil 21 transcribe | transferred to the cutting blade 11 can be adjusted easily.

  In this embodiment, the roll shafts 23a and 24a are moved by the screws 28a and 28b. However, the grooves 27a and 27b may be moved back and forth by hydraulic pressure or the like.

The oil pan 22 is an oil reservoir for storing the application oil 21, and is positioned with respect to the supply roll 23 so that the surface of the supply roll 23 is immersed in the application oil 21 stored in the oil pan 22.
When the bracket 27 is attached to the oil pan 22 and the oil supply device 20 is integrated with the supply roll 23 and the transfer roll 24, the oil supply device 20 is pulled apart from the cut roll 12 as shown in FIG. This is convenient for maintenance of the apparatus.

  Although the above-mentioned embodiment shows an example of the present invention, the present invention is not limited to the embodiment, and includes any modification that does not contradict the gist of the present invention. Accordingly, non-essential changes in configuration, omission of some configurations, replacement, addition of known means, and the like can be made as appropriate.
