短繊維を混合したものを用いることは知られている。(Prior Art) It has been known to use a resin material having rubber-like elasticity mixed with short glass fibers as a belt molding material in order to increase tensile strength and tensile modulus.

が回転駆動されるようになっている。An example of a belt having such a composition is a bin tractor belt used in a paper feeding device shown in FIG. A bin tractor 1 is attached to a guide shaft 3 having a circular cross section at a distance corresponding to the width of the paper S, and the bin tractor 1 engages with a feed hole S□ provided on both side edges of the paper S. The bin tractor belt 6 has a plurality of bins 4 protruding from the surface of a belt base band at regular intervals and teeth 5 provided on the back surface.
By rotationally driving the paper S, the paper S is fed at a substantially constant speed. The toothed portion of the bin tractor belt 6 meshes with a drive toothed pulley 7 that is connected to the drive shaft 2 and fixed only in the circumferential direction, and thereby the bin tractor belt 6
is designed to be rotationally driven.

Since the bin tractor belt 6 is wound between the driving toothed pulley 7 and the guide portion 8a protruding from the frame 8, when used for a long time under high load and high speed conditions, the belt The short fibers blended into the molding material make the belt 6
Wear occurs in the toothed pulley 7 with which the belt 6 engages and the guide portion 8a on which the belt 6 slides by friction. This tendency is particularly noticeable at the end (part A) of the guide portion 8a of the frame 8, and the resulting abrasion powder scatters and accumulates on various parts of the bin tractor 1, spoiling the appearance of the bin tractor 1, and the abrasion powder is used for driving. It invades the bearing part of the toothed boot and significantly increases the rotational torque of the drive toothed boot. Furthermore, when uneven wear occurs, the pin tractor benote 6 moves unevenly, and sliding resistance with the wall surface is added, which may further increase the rotational torque in mm. This increase in rotational torque must be suppressed because it causes tearing of holes in the paper, misaligned printing, skipped teeth, and the like.

However, since the reinforcing effect (tensile modulus, tensile strength) is lower than that of short glass fibers, the belt stretches easily, lacks paper feeding accuracy, and is costly. Becomes high.

摩擦摩耗試験を行った結果を表２に示す。Test 1 The above-mentioned invention examples 1 and 2 and comparative example 1. Regarding 2.3.4゜5, ASTMI tensile specimens and cylindrical friction wear specimens were molded using a batten felt injection molding machine, and tensile tests were conducted.
Table 2 shows the results of the friction and wear test.

動時に、相手材の摩耗が非常に大きい。Comparative Example 1 is an elastomer reinforced with short glass fibers used in conventional bin tractor belts, but the wear of the mating material is extremely large during frictional sliding.
本発明例１．２はアラミド短ｍ維をガラス短繊維に混合
使用したものであるが、摩擦摺動相手材の摩耗は非常に
少ない。Inventive Example 1.2 uses short aramid fibers mixed with short glass fibers, and the wear of the friction sliding mating material is very small.
比較例２〜５は、その他補強剤をガラス短繊維に混合使
用したものであるが、いずれも本発明例１．２に比べる
と相手材の摩耗は大きい。In Comparative Examples 2 to 5, other reinforcing agents were mixed with short glass fibers, but in all of them, the wear of the mating material was greater than in Inventive Examples 1.2.
したがって、ポリエステルエラストマー・ガラス短繊維
・アラミド短繊維配合系が望ましいことがわかる。Therefore, it can be seen that a system containing polyester elastomer, short glass fibers, and short aramid fibers is desirable.
本発明例１．２の場合に、相手材の摩耗が少ないのは、
アラミド繊維は３００℃身上の耐熱性があり、摩擦面の
発熱に十分耐え、柔軟性があり、ｒ！！腔界面の応力を
緩和させ、耐摩耗性が最も良い繊維であるからと考えら
れる。In the case of Inventive Example 1.2, the reason why there is less wear on the mating material is because
Aramid fiber has a heat resistance of 300℃, can withstand heat generated by friction surfaces, is flexible, and has r! ! This is thought to be because it relieves stress at the cavity interface and is the fiber with the best wear resistance.

維配合量は１５重量部で一定とした。Test 2 Tensile tests and friction and abrasion tests were conducted on polyester elastomer, short glass fibers, and short aramid fibers by changing the blending ratio of short glass fibers and short aramid fibers. In addition, the blended amount of short fibers was kept constant at 15 parts by weight.
繊維分比率と引張降伏強さ・相手材の摩耗係数（相手材
：ポリアセタール−ジュラコンＭ９０−０２）の関係は
第１図のようになった。The relationship between the fiber content ratio, tensile yield strength, and wear coefficient of the mating material (component material: polyacetal-Duracon M90-02) was as shown in FIG.
第１図より、アラミド繊維分率２５％以下では摩擦摺動

ミド繊維分率が５０％以上に増加すると、引張降伏強さ
が大巾に低下し、且つコストも割高となり問題となる。From Figure 1, it can be seen that when the aramid fiber fraction is less than 25%, the effect of preventing the wear of the flat material during friction sliding is small, but on the contrary, when the aramid fiber fraction increases to 50% or more, the tensile yield strength decreases. This becomes a problem as the cost decreases significantly and the cost becomes relatively high.
従って、適当なアラミド繊維分率は２５〜５０％である
。Therefore, a suitable aramid fiber fraction is 25-50%.

A conveyed object 23 is wound between the pulleys 21 and 22, and a bin of a bin tractor belt 11 applied to a bin tractor 24 is engaged with a feed hole (not shown) of the conveyed object 23, The drive toothed pulley 25 was driven at 70 rpm with a belt load of 1 kg to cause the bin tractor belt 11 to travel. At that time, the rotational torque before running (at no load), 10
Rotational torque after 0 hours (no load).

測定した。その結果を表３に示す。The wear amount of the guide part (polyacetal, Duracon M90-02) of the frame of the bin tractor and the permanent elongation of the belt were measured. The results are shown in Table 3.

びも少ない。In Comparative Example 1, the guide part was severely worn, and the rotation after running was
Luc is also big. Further, in Comparative Example 2.3, there is almost no wear on the guide part, but belt elongation is large, and proper paper feeding cannot be performed.In Inventive Example 1.2, there is little wear on the guide part, and belt elongation is also small.
試験４
マトリックスに対するガラス短繊維配合量を変えた材料
でビントラクタベルトを射出成形し、ビントラクタベル
ト走行試験を行った。試験方法は試験３と同じである。Test 4 Bin tractor belts were injection molded using materials in which the blended amount of short glass fibers in the matrix was varied, and a running test of the bin tractor belt was conducted. The test method is the same as Test 3.

ラクタベルトとしては不満足である。In Comparative Example 1, the rotational torque before and after running is low, and the wear of the guide portion of the frame due to running is small, but the permanent elongation of the belt after running is very large. This means that the belt tensile strength is insufficient with respect to the load applied to the belt, which is unsatisfactory as a bin tractor belt.
本発明例１，２は走行前後の回転トルク、走行後フレー
ム案内部摩耗量及び走行後ベルト永久伸び共に一応満足
できる水準である。In Examples 1 and 2 of the present invention, the rotational torque before and after running, the wear amount of the frame guide portion after running, and the permanent elongation of the belt after running are all at a somewhat satisfactory level.
比較例２は走行後ベルト永久伸びは殆んど無く非常に好
ましいが５反面走行時のフレーム案内部摩耗が激しく、
また走行前後の回転トルクも大きいためビントラクタベ
ルトとしては不満足である。Comparative Example 2 has almost no permanent elongation of the belt after running, which is very preferable, but on the other hand, the frame guide part wears heavily during running.
Furthermore, the rotational torque before and after running is large, making it unsatisfactory as a bin tractor belt.
従って、これらの試験結果からガラス短繊維配合量は１
０〜１５重量部が適当である。Therefore, from these test results, the blended amount of short glass fibers is 1
0 to 15 parts by weight is suitable.

くなる。また。Therefore, if a bin tractor belt is molded using a molding material made by mixing polyester elastomer with a predetermined amount of short glass fibers and short aramid fibers, there will be no scattering of abrasion powder, the bin tractor will not get dirty, and the rotational torque will be increased by use. This eliminates wear on the frame guide portion. Also.
高速、高荷重下にも正確な用紙送りができ、その際摩擦
摺動音が非常に低く、用紙の紙送り孔の破れがなくなる
。Accurate paper feeding is possible even at high speeds and under heavy loads, with very low frictional sliding noise and no tearing of paper feeding holes.

ことができる。Although the above-mentioned bin tractor belt is a coreless belt that does not have a core, the present invention is not limited to coreless belts, but includes polyamide fibers, aromatic polyamide fibers, polyester fibers,
The present invention can also be applied to belts in which a core body made of a fiber material such as glass fiber or carbon fiber or a steel cord is embedded.
