Description

  The present invention relates to a cleaning device that removes a sealer (sealer dirt) attached to a spatula for finishing a sealer (sealing agent) applied to a joint portion between members of, for example, an automobile hood or door.

  Conventionally, a sealer is applied to a joint portion between members constituting an automobile hood, a door, or the like. The sealer is sealed by moving the sealer coating device along the joint of the sealing member by bringing the sealer coating device (nozzle) closer to the joint of the sealed member such as a hood or door. It is applied to the joints of the members. When the application of the sealer by the sealer application device is finished, the sealer finish for the applied sealer is performed by the finishing spatula. Then, after the sealer is finished, the sealer is solidified to ensure waterproofness, rust prevention, and the like at the joint portion of the sealed member.

Here, after finishing the sealer, sealer (sealer dirt) is adhered to the finishing spatula. If the finishing spatula is used in such a state, the sealer finish cannot be performed with high accuracy. For this reason, it was necessary to remove the sealer dirt adhering to the finishing spatula after finishing the sealer. In order to remove the spatula stain of such a spatula, it is common to scrape the soiled surface of the spatula using the edge of a straight plate. An apparatus has also been proposed in which a scraping member is brought into contact with two surfaces (back and front) of a spatula to simultaneously remove dirt adhering to the two surfaces (back and front) of the spatula (Patent Document 1).
Utility Model Registration No. 3112813

However, in the above-described conventional technology, when the spatula is cleaned, the sealer dirt on the surface that is in contact with the plate or the scraping member is removed, but the sealer dirt attached to the other surface can be removed. There wasn't. Further, when the spatula is cleaned, the sealer dirt removed from the surface in contact with the plate or the scraping member may wrap around the other surface and be attached again.
For these reasons, it is necessary to scrape the sealer several times in order to clean the spatula, resulting in a problem that the cleaning time becomes long.

  Therefore, the present invention has been made to solve the above-described problems, and provides a sealer finishing spatula cleaning device capable of efficiently removing sealer dirt adhering to a sealer finishing spatula in a short time. This is the issue.

  In the cleaning device for a spatula finishing spatula according to the present invention made to solve the above problems, in the cleaning device for a sealer finishing spatula that removes deposits attached to the spatula finishing spatula, on the finished surface of the spatula A finishing surface cleaning unit that contacts the side surface cleaning unit that contacts both side surfaces adjacent to the finishing surface of the spatula, and each of the side surface cleaning units is brought into contact with the finishing surface cleaning unit. A spatula finishing spatula cleaning device, characterized in that the spatula finishing spatula cleaning device is provided at both ends of the finishing surface cleaning part so that both side surfaces of the spatula are in contact with each other.

  In the sealer finishing spatula cleaning device, the finished surface of the spatula comes into contact with the finished surface cleaning portion, and the sealer dirt adhering to the finished surface is scraped off and removed. Further, both side surfaces adjacent to the finished surface of the spatula come into contact with each side surface cleaning portion, and the sealer dirt adhering to each side surface is scraped off and removed. And each side surface cleaning part is provided in the both ends of a finishing surface cleaning part so that the both sides | surfaces of a spatula may contact when a spatula is made to contact a finishing surface cleaning part. That is, when cleaning the spatula, the finished surface of the spatula comes into contact with the finished surface cleaning unit, and both side surfaces of the spatula come into contact with the side surface cleaning unit. Thereby, the sealer dirt adhering to the finishing surface and both sides of the spatula can be scraped off and removed at the same time by a single cleaning operation. In addition, the sealer dirt can be prevented from wrapping around the other surface. Therefore, according to the sealer finishing spatula cleaning device, the sealer dirt adhering to the spatula can be efficiently removed in a short time.

  In the sealer finishing spatula cleaning apparatus according to the present invention, the side surface cleaning portion is provided with an edge portion that makes line contact with the side surface of the spatula and a flank surface that is formed so as not to contact the side surface of the spatula. It is desirable that

  Thus, by providing an edge part and a flank in a side surface cleaning part, the both sides | surfaces of a spatula can be made to line-contact with a side surface cleaning part reliably. Then, when both sides of the spatula are in line contact with the side surface cleaning portion, when scraping off the sealer dirt, the resistance (friction) force when the spatula and the cleaning device are relatively moved can be reduced. . For this reason, it is possible to prevent problems caused by an increase in the resistance (friction) force such as damage to the cleaning device or spatula and residual dirt.

  Here, when the sealer dirt is scraped off, if the finish surface of the spatula is damaged, the next sealer finish cannot be performed with high accuracy. For this reason, the cleaning device is required not to damage the finished surface of the spatula during cleaning.

  Therefore, in the sealer finishing spatula cleaning apparatus according to the present invention, it is desirable that the finished surface cleaning part is formed of a material having lower hardness and elasticity than the spatula material.

  By doing so, even if the finishing surface of the spatula is strongly pressed against the finishing surface cleaning part, the finishing surface of the spatula is not damaged when removing the sealer dirt. And since the force which presses a spatula against a finishing surface cleaning part can be strengthened, the sealer dirt adhering to the finishing surface of a spatula can be removed reliably. That is, it is possible to improve the removal performance of the sealer dirt adhered to the finished surface of the spatula without damaging the finished surface of the spatula.

  In the spatula finishing spatula cleaning device according to the present invention, the side surface cleaning portion is formed of a material having lower hardness and elasticity than the spatula material, and the spacing between the side surface cleaning portions is The width dimension of the spatula is preferably set slightly smaller.

  In this way, the side surface cleaning part is made of a material having lower hardness than the material of the spatula and having elasticity, and by setting the arrangement interval of each side surface cleaning part slightly smaller than the width dimension of the spatula, A side cleaning part (edge part) can be slightly bited into both side surfaces. Thereby, the removal performance of the sealer dirt adhering to both sides of the spatula can be improved. Further, it is possible to reliably prevent the sealer dirt from entering from the both sides of the spatula to the other side. In addition, since it is the edge part front end to bite into the both sides | surfaces of a spatula, there is almost no influence on the resistance (friction) force at the time of moving a spatula and a cleaning apparatus relatively (it does not become large).

  In the sealer finishing spatula cleaning device according to the present invention, it is desirable that the finished surface cleaning portion and the side surface cleaning portion are integrally formed products.

  By configuring the finished surface cleaning part and the side surface cleaning part by integral molding, the dimensional accuracy of the cleaning device is improved. As a result, the removal performance of the sealer dirt adhering to the spatula can be improved, and the cleaning device is inexpensive. Can be made.

  According to the sealer finishing spatula cleaning device of the present invention, as described above, the sealer dirt adhering to the sealer finishing spatula can be efficiently removed in a short time.

FIG. 4 is a diagram for explaining the dimensional relationship between the cleaning member and the finishing spatula.

  As shown in FIG. 1, the sealer cleaning device 10 according to the present embodiment includes a cleaning member 11 and a collection box 12. The cleaning member 11 is fixed to the collection box 12. Thereby, the sealer dirt adhering to the spatula finishing spatula 14 (see FIG. 2) is removed, and the removed sealer dirt is collected.

  Here, the finishing spatula 14 is a resin plate having a predetermined thickness (about 1 to 2 cm) as shown in FIG. 2, and a taper is formed so that the thickness decreases toward the tip. Has been. This tapered surface is a finished surface 14a for performing sealer finishing, and its tip is bent. And both side surfaces 14b and 14b are formed adjacent to the finishing surface 14a. On the other hand, a gripping portion 15 for gripping the spatula is formed at the base of the spatula 14. Sealing with the spatula 14 is performed while holding the gripping portion 15 and pressing the finished surface 14a against the sealer applied to the joint portion of the member to be sealed.

  The cleaning member 11 for cleaning the sealer dirt adhering to the finishing spatula 14 is a resin plate having a predetermined thickness (about 1 to 2 cm) as shown in FIG. A recess 20 is formed to match the shape of the spatula 14. The cleaning member 11 is an integrally molded product and is formed of a material (resin) having a lower hardness than the material (resin) of the finishing spatula 14. Since the cleaning member 11 is integrally molded as described above, the dimensional accuracy is improved. As a result, the contact between the cleaning member 11 and the finishing spatula 14 is improved. Can be improved. Moreover, the sealer cleaning apparatus 10 can be made inexpensive.

  A finished surface cleaning portion 21 is formed at the bottom of the recess 20 of the cleaning member 11. The finished surface cleaning unit 21 contacts the finished surface 14a of the finishing spatula 14 to remove sealer dirt. Further, side surface cleaning portions 22, 22 are formed on both side surfaces of the recess 20. That is, the side surface cleaning parts 22 and 22 are provided at both ends of the finished surface cleaning part 21. Each side surface cleaning part 22 contacts each side surface 14b of the finishing spatula 14 to remove sealer dirt. And each side surface cleaning part 22 is arrange | positioned so that both the side surfaces 14b and 14b may contact when the finishing surface 14a of the finishing spatula 14 is made to contact the finishing surface cleaning part 21. FIG. Thus, as shown in FIG. 4, when the finishing spatula 14 is disposed in the recess 20 of the cleaning member 11, the finishing surface 14a of the spatula 14 contacts the finishing surface cleaning portion 21, and both side surfaces 14b of the spatula 14 14 b comes into contact with the side surface cleaning part 22.
