Abstract

PROBLEM TO BE SOLVED: To provide a lubricant coating tool and a lubricant coating device which can stably perform coating of a lubricant when position variation of a paper-like component occurs.SOLUTION: According to a lubricant coating tool 80 and a lubricant coating device 90 of the present invention, a lubricant is coated by a peripheral surface of a substantially columnar capillary fiber bundle 30, and the capillary fiber bundle 30 is energized to a paper-like component 10 side by an elastic member 54 and three-dimensionally moves following to position variation of the paper-like component 10. Therefore, a side face 11 of the paper-like component 10 does not happen to drop from a coating surface (circumferential surface) of the capillary fiber bundle 30. Further, even if position variation such as twisting occurs in the paper-like component 10, a great change does not occur in a contact state (contact angle and so on) between the side face 11 of the paper-like component 10 and the capillary fiber bundle 30. Thus, coating of the lubricant can be always stably carried out.

Description

  The present invention relates to a lubricant applicator and a lubricant applicator for applying a lubricant to a side surface of a paper-like member having an adhesive layer.

  Seals and labels that are printed on the front surface and have an adhesive layer on the back surface are widely used in various products and applications. The general paper-like member 10 used for these seals and labels is mainly composed of a surface base material 10a, an adhesive layer 10b, and a separator 10c, as shown in a partially enlarged view surrounded by a circle in FIG. . The surface base material 10a is paper or a synthetic resin film on which printing or the like is performed, and the pressure-sensitive adhesive layer 10b is bonded to the back surface. The separator 10c is a paper or synthetic resin film that has been subjected to a release treatment on one surface side, and the surface base material 10a is temporarily adhered to the release treatment surface by the adhesive layer 10b. Then, the surface base material 10a on which the printed matter is formed is peeled off from the separator 10c together with the pressure-sensitive adhesive layer 10b, and the surface base material 10a is adhered to the article by adhering to the article intended for the pressure-sensitive adhesive layer 10b.

  Processing such as printing on the paper-like member 10 is often carried out continuously by unrolling the roll-like paper-like member 10 (raw roll) while being unrolled. Such a processing device for the paper-like member 10 has a guide portion for positioning the paper-like member 10 and a paper feeding means for conveying the paper-like member 10. However, since the pressure-sensitive adhesive layer 10 b is exposed on the side surface 11 of the paper-like member 10, the pressure-sensitive adhesive of the pressure-sensitive adhesive layer 10 b adheres to the guide portion that contacts the side surface 11 of the paper-like member 10. It gradually accumulates with the conveyance of 10. The accumulation of the pressure-sensitive adhesive hinders smooth conveyance of the paper-like member 10 and also adversely affects processing such as printing on the paper-like member 10.

  Conventionally, spraying silicon spray or spraying baby powder has been used as a technique for preventing adhesion of these adhesives. However, in addition to insufficient adhesion prevention effects by these methods, there are many practical problems such as health damage caused by the operator's suction and occurrence of defects due to adhesion to the equipment side. For this reason, it is common that removal of the adhesive which adhered is performed by an operator's cleaning, and this cleaning operation became a big factor which reduces the operation rate of a processing apparatus.

  In order to solve this problem, the inventor of the present application has invented a lubricant supply tool and a supply method described in [Patent Document 1] below. In the invention described in [Patent Document 1], the lubricant is directly applied to both side surfaces 11 of the paper-like member 10 to prevent the adhesive from adhering to the guide portion or the like. As a result, the paper-like member 10 can be continuously processed without frequently cleaning the guide portion and the like.

Japanese Patent No. 4891447

  However, the paper-like member 10 sent to the lubricant supply device is subject to positional fluctuations such as fluttering and deviation that differ depending on the production lot, dry state, humidity, weather conditions, and the like. However, in the lubricant supply device described in [Patent Document 1], since the lubricant is applied with a relatively small-diameter circular felt, the side surface 11 of the paper-like member 10 is large when the position variation of the paper-like member 10 is large. However, there is a problem that the lubricant cannot be applied due to dropping off from the application surface of the circular felt. In addition, since the amount of lubricant applied depends on the contact area between the side surface 11 of the paper-like member 10 and the coated surface, the amount of lubricant applied by the lubricant supply tool described in [Patent Document 1] varies depending on the position variation. There is a problem of being influenced.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a lubricant applicator and a lubricant applicator capable of stably applying a lubricant even when the position of a paper-like member changes. To do.

The present invention
(1) A lubricant applicator for applying a lubricant to a side surface 11 of a paper-like member 10 provided with an adhesive layer 10b and a surface base material 10a,
A capillary fiber bundle 30 that is formed in a substantially cylindrical shape with fine fibers and infiltrated with a lubricant by capillary action, and the peripheral surface and the side surface 11 of the paper-like member 10 are in contact with each other to apply the lubricant to the side surface 11; ,
A supply unit 40 for supplying a lubricant to the capillary fiber bundle 30 using a capillary phenomenon;
A head portion 50 that is sandwiched so that the peripheral surface of the capillary fiber bundle 30 is exposed;
A holder portion 52 for holding the head portion 50 in a three-dimensionally movable state;
And an elastic member 54 that is installed between the holder portion 52 and the head portion 50 and biases the circumferential surface of the capillary fiber bundle 30 toward the side surface 11 of the paper-like member 10. By providing the lubricant applicator 80, the above-described problems are solved.
(2) The head unit 50 sandwiches the plurality of capillary fiber bundles 30, the side surface 11 of the paper-like member 10 is continuously in contact with the peripheral surface of the plurality of capillary fiber bundles 30, and the number of the capillary fiber bundles 30 is determined. The above problem is solved by providing the lubricant applicator 80 according to (1) above, wherein the amount of lubricant applied to the paper-like member 10 is adjusted by changing the amount.
(3) A lubricant application device that is installed in a device 100 including a paper feeding means (conveying roller 20) for conveying the paper-like member 10 and applies a lubricant to the side surface 11 of the paper-like member 10,
The lubricant applicator 80 according to the above (1) or (2) is installed on the upper side of the paper feeding means so as to oppose each other, and both side surfaces 11 of the paper-like member 10 are opposed to each other. The head portion 50 is moved in a direction substantially perpendicular to the axis of the capillary fiber bundle 30 while being in contact with the peripheral surface of each capillary fiber bundle 30 between 80 and the position of the head member 50 when the paper member 10 is fed. The above-mentioned problem is solved by providing a lubricant application device 90 that moves three-dimensionally in response.

  The lubricant applicator and the lubricant applicator according to the present invention apply the lubricant on the peripheral surface of the substantially cylindrical capillary fiber bundle. Further, the head portion of the lubricant applicator moves three-dimensionally according to the position variation of the paper-like member. Thereby, it is possible to prevent the paper-like member from dropping from the application surface. Further, it is possible to stably apply the lubricant even when the position of the paper member is changed. Further, the amount of lubricant applied can be adjusted by the number of capillary fiber bundles.

It is a figure which shows the lubricant applicator which concerns on this invention. It is the side view and sectional drawing of the lubricant applicator which concern on this invention. It is a figure explaining the use condition of the lubricant applicator and lubricant applicator according to the present invention. It is a figure which shows the example of application of the lubricant coating device which concerns on this invention.

  Embodiments of a lubricant applicator and a lubricant applicator according to the present invention will be described with reference to the drawings. Here, FIG. 1 is a view showing a lubricant applicator 80 according to the present invention. FIG. 2A is a side view of the lubricant applicator 80. Moreover, FIG.2 (b) is XX sectional drawing of Fig.2 (a).

  A lubricant applicator 80 shown in FIGS. 1 and 2 applies a lubricant to a side surface 11 of a paper-like member 10 having a surface base material 10a and an adhesive layer 10b, and a capillary fiber bundle 30; Supply unit 40 that supplies a lubricant to the capillary fiber bundle 30, a head unit 50 that is sandwiched so that the peripheral surface of the capillary fiber bundle 30 is exposed, and a holder unit that holds the head unit 50 in a three-dimensionally movable state. 52, and an elastic member 54 installed between the holder portion 52 and the head portion 50. The lubricant used here is a liquid that prevents the adhesive from adhering to other members and reduces frictional resistance.

  The capillary fiber bundle 30 is formed by forming fine fibers into a substantially columnar shape, and the fine fibers themselves or the gaps between the fine fibers have a water absorption function by capillary action. The material used for the capillary fiber bundle 30 may be any material such as synthetic resin fiber or natural fiber. In addition, the side surface 11 of the paper-like member 10 moves while contacting the circumferential surface of the capillary fiber bundle 30 in a substantially orthogonal direction. For this reason, the fine fibers are aligned substantially in the axial direction (longitudinal direction) of the cylinder so that fuzz and the like do not stand up as much as possible on the peripheral surface of the capillary fiber bundle 30, and are solidified with resin or the like to such an extent that the water absorbing function is not impaired It is preferable to give hardness.

  The supply unit 40 that supplies the lubricant to the capillary fiber bundle 30 has one end in contact with the infiltrating body 42 installed in the head unit 50 and the other end immersed in the lubricant stored in the lubricant tank 12. . Then, the supply unit 40 absorbs the lubricant in the lubricant tank 12 by its own capillary phenomenon and supplies it to the capillary fiber bundle 30 via the infiltrating body 42. The supply unit 40 may have any shape such as a string shape, a cloth shape, or a belt shape as long as it has an appropriate water absorption function due to a capillary phenomenon. Moreover, any material such as synthetic resin fiber and natural fiber may be used in the same manner as the capillary fiber bundle 30. As a member suitable for this supply part 40, the cotton string currently distribute | circulated cheaply is mentioned. The supply unit 40 is preferably passed through the tube 44 to prevent the lubricant from adhering to an operator or the like, and the supply unit 40 from being contaminated.

  The infiltrating body 42 transmits the lubricant from the supply unit 40 side to the capillary fiber bundle 30 side, and any material such as felt or sponge may be used as long as the lubricant infiltrates. The infiltrating body 42 is particularly effective when a lubricant is transmitted from a single supply unit 40 to the plurality of capillary fiber bundles 30, but the capillary fiber bundle 30 directly from the supply unit 40 without using the infiltrating body 42. You may make it transmit a lubricant to. Further, one end of the capillary fiber bundle 30 may be immersed in a lubricant so that a part of the capillary fiber bundle 30 also serves as the supply unit 40.

  The head portion 50 is sandwiched and held so that the peripheral surface of the capillary fiber bundle 30 is exposed, and is preferably substantially U-shaped or substantially U-shaped to hold the vicinity of both ends of the capillary fiber bundle 30. The head portion 50 does not need to expose the peripheral surface of the capillary fiber bundle 30 over the entire periphery, and it is sufficient that at least the contact surface side with the paper-like member 10 is exposed. Therefore, the capillary fiber bundle 30 is also held from the circumferential surface side by bringing the circumferential surface opposite to the contact surface of the capillary fiber bundle 30 into contact with the bottom surface of the concave portion of the head portion 50, and the capillary fiber accompanying the contact with the paper-like member 10. The bending of the bundle 30 may be prevented. Furthermore, a groove having the same dimensions as the peripheral surface of the capillary fiber bundle 30 is formed on the bottom surface of the concave portion of the head portion 50, and the capillary fiber bundle 30 is partially inserted and held in the groove, thereby further bending the capillary fiber bundle 30. You may make it prevent.

  In addition, it is preferable to install a plurality of capillary fiber bundles 30 side by side on the head unit 50. According to this configuration, since the side surface 11 of the paper-like member 10 and the capillary fiber bundle 30 are in contact at two or more points, the head unit 50 is maintained substantially parallel to the side surface 11 of the paper-like member 10. As a result, the head unit 50 can accurately move following the position variation of the paper-like member 10.

  Moreover, the lubricant applicator 80 according to the present invention adjusts the amount of lubricant applied to the paper-like member 10 by increasing or decreasing the number of capillary fiber bundles 30 installed in the head unit 50. The increase or decrease of the capillary fiber bundle 30 may be performed by preparing a plurality of head parts 50 having different numbers of installed capillary fiber bundles 30 and appropriately replacing them. For example, the capillary fiber bundle 30 can be opened and closed. It is possible to increase or decrease the number.

  The holder portion 52 holds the head portion 50 in a three-dimensionally movable state, and has, for example, a substantially U-shape. Then, for example, shaft holes 58 are formed in both side walls of the holder portion 52, and holding shafts 56 formed on both side surfaces of the head portion 50 are inserted into the shaft holes 58 to hold the head portion 50. At this time, the size of the shaft hole 58 is made sufficiently larger than the holding shaft 56, and the head portion 50 is within the movable range of the holding shaft 56 by making the holding shaft 56 long enough not to fall off the holder portion 52. It can move freely vertically and horizontally. Further, the head swings freely within the movable range of the holding shaft 56.

  An elastic member 54 that urges the peripheral surface of the capillary fiber bundle 30 toward the side surface 11 of the paper-like member 10 is installed between the holder portion 52 and the head portion 50. The elastic member 54 is not particularly limited, and a known elastic member such as a leaf spring or a coil spring can be used. Then, the elastic member 54 urges the capillary fiber bundle 30 to the paper-like member 10 side via the head part 50, so that the head part 50 moves three-dimensionally so as to follow the positional fluctuation of the paper-like member 10. The contact state between the peripheral surface of the capillary fiber bundle 30 and the side surface 11 of the paper-like member 10 is stably maintained.

  The moving mechanism of the head unit 50 by the holding shaft 56, the shaft hole 58, and the elastic member 54 is an example, and is not particularly limited thereto.

  Next, the configuration and operation of the lubricant application device 90 including the lubricant applicator 80 will be described with reference to FIGS. Although FIG. 4 shows an example in which the lubricant application device 90 is applied to a printing machine, the present application is not limited to this, and any device equipped with a paper feeding means, such as a cutting machine, a slitter machine, or a punching machine. It can also be applied to on-demand printers and other office equipment. In this example, an example in which the lubricant is applied to the paper-like member 10 provided with the separator 10c has been described. However, the present invention can also be applied to the paper-like member 10 that does not include the separator 10c. . For example, in a seal printing machine of a type in which an adhesive is applied in an apparatus and the adhesive layer 10b is formed on the surface base material 10a, a lubricant is applied to the side surface 11 of the paper-like member 10 after the adhesive layer 10b is formed. Apply. In manufacturing equipment such as an adhesive tape, the lubricant is applied after the adhesive layer 10b is formed on the tape (corresponding to the surface base material 10a). In addition, in a device for attaching a protective film (without separator 10c) or the like provided with a pressure-sensitive adhesive layer 10b to a printed matter or other articles, a lubricant is applied after the roll-shaped protective film (paper-like member 10) is rolled up. .

  The lubricant application device 90 according to the present invention shown in FIGS. 3 and 4 is installed in a device 100 that is provided with a paper feeding means such as a conveyance roller 20 that conveys the paper-like member 10, and is shown in FIG. As described above, the lubricant applicator 80 is disposed on the upper side of the paper feeding means of the device 100 so as to face each other. The installation direction of the lubricant applicator 80 at this time is a direction in which the axis of the cylinder of the capillary fiber bundle 30 is substantially orthogonal to the feeding direction of the paper-like member 10. 3 and 4 show an example in which one lubricant applicator 80 is installed on each of the left and right sides. However, the number of lubricant applicators 80 is not limited to this. Any number of agents may be installed depending on the amount of agent applied. The amount of lubricant applied may be adjusted according to the number of lubricant applicators 80 installed.

  The place where the lubricant applicator 80 is installed on the device 100 is not particularly limited as long as it is on the upper side of the paper feeding means. However, when the lubricant application device 90 is installed in the device 100 that can handle the paper-like member 10 having different widths, the distance between the lubricant applicators 80 can be adjusted according to the width of the paper-like member 10. There is a need. As an example of the position adjustment mechanism of the lubricant applicator 80, a shaft is installed in the width direction of the paper-like member 10, and the lubricant applicator 80 is moved along the shaft by inserting the holder portion 52 into the shaft. Possible configurations are listed. If the lubricant applicator 80 is installed in the positioning guide portion 22 on the upper side of the paper-like member 10, the position adjustment of the lubricant applicator 80 is performed at the same time as the position of the guide portion 22 is adjusted.

  When the lubricant applicator 80 is installed in the device 100, the supply unit 40 absorbs the lubricant stored in the lubricant tank 12 by capillary action and supplies it to the capillary fiber bundle 30. Thereby, the lubricant is infiltrated into the capillary fiber bundle 30.

  In addition, the roll roll 13 is rotatably installed on the device 100. Then, one end of the roll raw fabric 13 is unwound and subjected to position regulation by the guide portion 22, and then communicated with the inside of the device 100 in a band shape. Note that a guide (not shown) other than the guide portion 22 is installed in the device 100, and the paper-like member 10 is not displaced in the device 100.

  When the apparatus 100 is activated, the transport roller 20 that is a paper feeding means rotates. When the transport roller 20 rotates, the roll material 13 rotates correspondingly, and the paper-like member 10 is rolled up. The rolled paper-like member 10 passes between the lubricant applicators 80. At this time, both side surfaces 11 of the paper-like member 10 move in a direction substantially orthogonal to the axis of the capillary fiber bundle 30 while contacting the peripheral surface of the capillary fiber bundle 30 infiltrated with the lubricant. When a plurality of capillary fiber bundles 30 are installed, the side surface 11 of the paper-like member 10 moves while continuously contacting the plurality of capillary fiber bundles 30. As a result, an appropriate amount of lubricant is applied to the side surface 11 of the paper-like member 10.

  When the lubricant is applied to the paper-like member 10, the supply unit 40 replenishes the capillary fiber bundle 30 with the lubricant accordingly. In addition, since the replenishment of the lubricant is performed by the capillary phenomenon of the supply unit 40, only the reduced amount of the lubricant due to the application is replenished and is not excessively supplied to the capillary fiber bundle 30. For this reason, for example, when the device 100 is stopped, the capillary fiber bundle 30 is not replenished with the lubricant. Therefore, dripping or the like due to excessive supply of the lubricant does not occur.

  The paper-like member 10 to which the lubricant is applied by the lubricant application device 90 is positioned by the guide portion 22 and then conveyed to various processing devices such as a printing device. At this time, the guide portion 22 and the side surface 11 of the paper-like member 10 are in contact with each other, but since the lubricant is applied to the side surface 11, the adhesive of the paper-like member 10 does not adhere to the guide portion 22 side. Further, the adhesive of the paper-like member 10 does not adhere to other guides and the like (not shown).

  Next, the paper-like member 10 is sent to, for example, a first printing device 2a as a processing device, and printing with the first color is performed on the surface base material 10a of the paper-like member 10. In general, printing is not performed on the edge of the surface base material 10a. For this reason, the lubricant applied to the side surface 11 of the paper-like member 10 does not adversely affect the printed matter of the surface base material 10a. The paper-like member 10 on which the first color printing has been performed is sent to the first drying device 4a, and the printed material is dried. When the printing apparatuses 2a, 2b, and 2c use ultraviolet curable ink, the drying apparatuses 4a, 4b, and 4c are UV irradiation drying apparatuses. When drying of the printed material by the drying device 4a is completed, the paper-like member 10 is sent to the second printing device 2b, and printing on the surface base material 10a with the second color is performed. Next, the paper-like member 10 is sent to the second drying device 4b, and the printed matter by the second color is dried. Next, the paper-like member 10 is sent to the third printing apparatus 2c, and printing with the third color is performed on the surface base material 10a. Next, the paper-like member 10 is sent to the third drying device 4c, and the printed matter by the third color is dried. As a result, a multicolored printed matter is formed on the surface base material 10 a of the paper-like member 10. Note that the processing of the paper-like member 10 by the device 100 is performed while repeating forward and backward movements as necessary.

  The paper-like member 10 on which the printed matter is formed is then sent to, for example, an outer shape cutting device 6 as a processing device. The outer shape cutting device 6 cuts a predetermined shape into the surface base material 10a and the adhesive layer 10b around the printed matter applied to the paper-like member 10. At this time, the separator 10c is not cut. The cut paper-like member 10 is then sent to the peeling portion 7 where the unnecessary surface base material 10a and adhesive layer 10b on the outer periphery of the seal are peeled and removed. The unnecessary surface base material 10a and the pressure-sensitive adhesive layer 10b which have been peeled off are wound up by the recovery roller 24 and discarded. As a result, only the seal obtained by cutting the printed material into a predetermined shape remains on the separator 10c. Next, the paper-like member 10 is sent to the cutting machine 8 and cut into a predetermined length. Thereby, the seal is completed.

  Note that the paper-like member 10 before being regulated by the guide portion 22 is subject to positional fluctuation such as fluttering and displacement. However, the lubricant applicator 80 and the lubricant applicator 90 according to the present invention apply the lubricant on the peripheral surface of the substantially cylindrical capillary fiber bundle 30, and the capillary fiber bundle 30 is paper-like by the elastic member 54. It is urged toward the member 10 side and moves three-dimensionally following the position variation of the paper-like member 10. For this reason, the side surface 11 of the paper-like member 10 does not fall off from the application surface (circumferential surface) of the capillary fiber bundle 30. Further, even if a positional variation such as twisting occurs in the paper-like member 10, for example, a large change does not occur in the contact state (contact angle or the like) between the side surface 11 of the paper-like member 10 and the capillary fiber bundle 30. Thereby, application | coating of a lubricant can always be performed stably.

  Furthermore, in the lubricant applicator 80 and the lubricant applicator 90 according to the present invention, the side surface 11 of the paper-like member 10 contacts the peripheral surface of the capillary fiber bundle 30 in a substantially point contact state. For this reason, even if a position change arises in the paper-like member 10, a big fluctuation | variation does not arise in the contact area of the paper-like member 10 and the capillary fiber bundle 30. FIG. As a result, the lubricant can always be applied in a stable coating amount. In addition, the amount of lubricant applied can be easily adjusted by changing the number of installed capillary fiber bundles 30.

  Note that the configurations of the lubricant applicator 80 and the lubricant applicator 90 shown in this example are merely examples, and the shape and dimensions of each member, the holding mechanism of the head unit 50, and the like are not limited to those described above. . Furthermore, the present invention can be modified and implemented without departing from the scope of the present invention.
