Field of the Invention The present invention relates to a temporary shaft of a slider for a linear motion guide bearing device used in a separately sold slider or the like. 2. Description of the Related Art A linear motion guide bearing device has a guide rail having a rolling element rolling groove extending in an axial direction on an outer surface thereof, and is fitted to the guide rail and faces the rolling element rolling groove. A slider having a load rolling element rolling groove, and a plurality of rolling elements rotatably mounted in a rolling element rolling path formed by the rolling element rolling groove and the load rolling element rolling groove. Device. The slider fitted to the guide rail smoothly moves relative to the guide rail along the guide rail through the rolling of the rolling element in the rolling element rolling path. The slider of such a linear guide bearing device may be sold as a single unit without being mounted on a guide rail. In such a case, the slider is temporarily mounted on a resin rail called a temporary shaft. It is often sold in an assembled state. That is, the temporary shaft is for temporarily assembling the slider before it is actually mounted on the guide rail. When the temporary shaft is attached to the end of the guide rail so as to be continuous, and the slider is slid from the temporary shaft to the guide rail, the slider assembled on the temporary shaft can be moved to the guide rail. . This temporary axis is
Conventionally, the slider is made of inexpensive resin because the slider is temporarily assembled. For example,
Those obtained by molding a polypropylene resin by a blow molding method and those obtained by molding a polyacetal resin by an injection molding method were common. [0005] After the slider is moved to the guide rail, the temporary shaft is no longer needed and is disposed of as waste. However, since the above-mentioned conventional temporary shaft is made of polypropylene resin, polyacetal resin or the like, it is often buried as incombustible waste. Therefore, the amount of waste is increased, which may be a cause of the waste problem. Accordingly, the present invention solves the above-mentioned problems of the temporary shaft of the conventional slider for the linear guide bearing device, and reduces the temporary shaft of the slider for the linear guide bearing device, which hardly causes a waste problem. The task is to provide [0007] In order to solve the above-mentioned problems, the present invention has the following arrangement. That is, the temporary shaft of the slider for a linear motion guide bearing device according to the present invention is a temporary shaft for temporarily assembling a slider that is slidably fitted to a guide rail of the linear motion guide bearing device. It is characterized by comprising a resin having a polyester component. [0008] Since the aliphatic polyester component having biodegradability is included in at least a part of the molecular structure, the resin has biodegradability. Therefore, when the temporary shaft composed of the resin is buried in soil, it is biodegraded and completely decomposed into carbon dioxide and water. It is unlikely to be a source of material problems. Examples of the aliphatic polyester component include polybutylene succinate, polyethylene succinate, polycaprolactone, polylactic acid, poly-3-hydroxybutyric acid, polyhydroxyvaleric acid, polybutylene succinate adipate and the like. The resin used in the present invention only needs to have the aliphatic polyester component as described above in at least a part of its molecular structure.Therefore, a resin having an aliphatic polyester component and an aromatic polyester component, A resin having a group III polyester component and a polycarbonate component can be used without any problem as long as it has biodegradability. For example, copolymers of aliphatic polyesters such as polybutylene succinate terephthalate and polyethylene succinate terephthalate and aromatic polyesters, and copolymers of aliphatic polyesters such as polybutylene succinate carbonate and polycarbonate. Coalescence. In addition, when an aliphatic polyether component is introduced into a part of the molecular structure, biodegradability can be improved. Therefore, a resin having both an aliphatic polyester component and an aliphatic polyether component in the molecular structure is used. Is preferred. Although the structure of the aliphatic polyether component is not particularly limited, a structure represented by the following chemical formula (Formula 1) is preferable since the resin can have excellent biodegradability. [0011] Here, the numerical values of n and m are not particularly limited, but n is preferably 2, 3, or 4, and m is an integer of 2 to 250, particularly preferably 2 to 100.
Further, the temporary shaft of the slider for a linear motion guide bearing device of the present invention is:
You may comprise the resin composition which mix | blended the additive with the above-mentioned resins. For example, to improve mechanical properties,
A resin composition to which a filler such as glass fiber is added may be used.
Considering the reinforcing effect, glass fiber or the like is preferable, but it is more preferable to use a filler that has a small adverse effect on the natural environment such as soil when the temporary shaft is biodegraded. For example, light calcium carbonate (crystal form is calcite, argonite), natural hydrous aluminum silicate (kaolin, clay), talc, bentonite, fibrous magnesium hydroxide, wollastonite, sepiolite, carbon black, mica, silicon dioxide And diatomaceous earth. The additives other than the filler include an antioxidant, a lubricant, an antistatic agent, a plasticizer, and the like. An embodiment of a temporary shaft of a slider for a linear motion guide bearing device according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a temporary shaft, and FIG.
FIG. 3 is a perspective view showing a temporary shaft in a state where the slider is assembled. Note that the present embodiment is an example of the present invention, and the present invention is not limited to the present embodiment. The temporary shaft 1 is formed in substantially the same shape as a guide rail for a linear guide bearing device. That is,
The cross-sectional shape broken along a plane perpendicular to the axis direction of the temporary shaft 1 is as follows:
It has substantially the same shape as that of the guide rail.
The ridge line where the upper surface 1a and the both side surfaces 1b of the square temporary shaft 1 intersect has a cross-section of approximately 1 /
A four-arc concave groove 2A is formed in the axial direction, and a substantially semicircular concave groove 2B corresponding to the rolling element rolling groove is formed in the axial direction at an intermediate position between both side surfaces 1b of the temporary shaft 1. I have. Further, an escape groove 3 for a ball retainer is formed in the groove bottom of the concave groove 2B formed at an intermediate position between the both side surfaces 1b, like the guide rail. However, unlike the guide rail, the temporary shaft 1 is for temporarily assembling the slider 5 and, as shown in FIGS. It is sufficient if the length is slightly longer than the length in the direction. Since the upper surface 1a of the provisional shaft 1 does not need to be functionally flat, a concave wall 4 is provided to improve the dimensional accuracy of the provisional shaft 1. Note that a reinforcing plate 4a for reinforcing the meat slack 4 is provided inside the meat slack 4. When the temporary shaft 1 on which the slider 5 is assembled is attached to the end of the guide rail so as to be continuous, and the slider 5 is slid from the temporary shaft 1 toward the guide rail,
The slider 5 assembled on the temporary shaft 1 can be moved to the guide rail. Such a temporary axis 1 is obtained by injection molding a biodegradable resin having an aliphatic polyester component in a molecular structure as shown in Table 1, or a resin composition in which a filler is mixed with the biodegradable resin. Manufactured. Therefore, when the temporary shaft 1 after moving the slider 5 to the guide rail is buried in the soil as waste, it is naturally biodegraded, so that it is less likely to adversely affect the natural environment. It is difficult to become. [Table 1] Here, various materials used (described in Table 1) will be described.・ Polylactic acid: LACTY903 manufactured by Shimadzu Corporation
0 ・ Poly-3-hydroxybutyric acid: Biogreen polybutylene succinate manufactured by Mitsubishi Gas Chemical Co., Ltd .: Bionole # 1020 manufactured by Showa Polymer Co., Ltd. ・ Polyacetal resin: Duracon M90-44 poly manufactured by Polyplastics Co., Ltd. Lactic acid, poly-3-hydroxybutyric acid, and polybutylene succinate are biodegradable resins having an aliphatic polyester component in the molecular structure, and polyacetal resins are non-biodegradable resins having no aliphatic polyester component in the molecular structure. It is a degradable resin. As the filler, calcium carbonate whisker (Argonite) manufactured by Maruo Calcium Co., Ltd.
Was used. The mixing ratio is as shown in Table 1. Next, a test was performed to evaluate the biodegradability of a temporary shaft manufactured by injection-molding a resin and a resin composition (Examples 1 to 5 and Comparative Example 1) as shown in Table 1. First, the method of the biodegradability test will be described. Introduced a temporary shaft together with the company's culture material and "Friends of the Earth" (trade name) into "Friends of the Earth" (trade name), a bio-type garbage decomposer manufactured by Takubo Kogyosho Co., Ltd. Biodegraded at 55-60 ° C. And the early 2
The time at which the weight became 0% or less, or the time at which the initial shape was not maintained, and the time at which the particles were separated were defined as the biodegradation completion time, and the biodegradability was evaluated based on the time. The test results are shown in Table 1. Table 1
The numerical value of the biodegradation completion time in is shown as a relative value when the biodegradation completion time in Example 1 is set to 1. Example 1
While the temporary axes of ~ 5 had excellent biodegradability,
The temporary axis of Comparative Example 1 was hardly decomposed even after 2000 hours, and the weight loss was slight. From this result, it can be seen that embedding processing in soil is possible by forming the temporary shaft of the slider for the linear motion guide bearing device with a resin having biodegradability. As described above, since the provisional shaft of the slider for a linear motion guide bearing device of the present invention is made of a biodegradable resin, it can be naturally buried in the soil. Biodegradable. Therefore, it is unlikely to cause a waste problem.
