構造及び製法に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a plain paper copying machine (hereinafter abbreviated as PPC copying machine).
The present invention relates to a rubber endless belt that can be suitably used for conveying paper sheets in computers, facsimile machines, etc., and particularly to an improved structure and manufacturing method thereof.
現在市販されているPPC複写機はメーカにより機構上

られる。PPC copying machines currently on the market have some differences in mechanism depending on the manufacturer, but the principle is as schematically shown in FIG. 2. To explain with reference to the same figure, first set the original and press the start button (not shown), then the original paper (P) is transferred from the single-sheet cassette (C) to the pair of timing rolls by the paper feed roll (R). (T, T), and the starting end of the photosensitive surface (S) of the photosensitive drum (D) is held between the rolls (T) and (T), and the starting end of the photosensitive surface (S) of the photosensitive drum (D) It is kept on standby until it reaches directly above (the position shown in the figure).

よりなる所望の文字または図形等が転写される。Next, when the starting end of the photosensitive surface (S) reaches the position shown in the figure, the timing rolls (T), (T) rotate, and the base paper (P) is sent out onto the conveyor belt (A). (P) is the bell) While being conveyed by (A), desired characters or figures made of a printing material such as carbon are transferred onto the surface of the photosensitive surface (S).
原紙(P)は、さらに搬送ベル) (A)により一対の
定着ロール(B、B)間へ送り込まれ、該ロール間を通
過中に加熱により表面の文字又は図形等が定着される。The base paper (P) is further fed between a pair of fixing rolls (B, B) by a conveyor belt (A), and while passing between the rolls, characters or figures on the surface are fixed by heating.

られるような原紙の進行方向に沿う“縮み”が生じる。As is clear from the above, once the tanning roll (T,
The base paper (P) sent to the copying area directly below the photosensitive drum (D) by T) has not yet been fixed with printing materials such as carbon for displaying transferred characters, figures, etc. on its negative side. Thereafter, until it passes between fixing rolls (B, B), it is placed on a conveyor belt (A) and is moved depending on the surface frictional force of the belt. Therefore, if the base paper (P) does not advance at the same and uniform speed as the conveyor belt (A) due to the surface friction force of the conveyor belt (A), the characters or figures to be transferred will "Shrinkage" occurs along the direction of movement of the base paper as seen in FIG. 3 (b).

A method of suctioning using (V) or the like is adopted. Note that a plurality of small ventilation holes (not shown) are bored in the conveyor bell l-(A) so that this suction force effectively acts on the base paper.

手間が掛かる上、該易滑性材料は一般的に高価である。By the way, while the base paper (P) passes through the vacuum suction area, each ventilation hole of the conveyor bell 1-(A) is sealed with the base paper (P), so the heald (A) is not connected to the vacuum suction device. is strongly attracted to the surface of the rotating shaft (E, E).
) causes circular motion. Therefore, it is preferable that the friction coefficient on the side where the first general feed heald (A) faces the vacuum suction device is as low as possible; if the friction coefficient is high,
Depending on the hardness of the rubber constituting the heald (A), the belt may wrinkle or meander. Needless to say, these inconvenient phenomena have a negative impact on the conveyance of the base paper (P) and, by extension, on the finished image. Therefore, in conventional equipment, in addition to coating the surface of the belt (A) or the surface of the vacuum suction device with a low-friction resin such as tetrafluoroethylene, a slight bulge was formed at the suction port of the vacuum suction device. Some methods have been adopted to prevent adsorption to the suction port by forming an opening edge, but this method requires extra effort to process the slippery material using such different materials, and Smooth materials are generally expensive.

。[Object of the Invention] The present invention provides a solution to the above-mentioned problems in the conventional conveyor heald of PPC copying machines, etc., and provides a high surface friction effect on the base paper and a low surface friction effect on the surface of the vacuum suction device. Paper sheet til that can exert a frictional effect and has excellent resistance to the tensile force received during circular motion.

該ゴムベルトに繊維補強層を埋設するとよい。As described above, the general feed heald is stretched between a pair of rotating shafts and is rotated by the rotating shafts, so that a tensile force acts on the heald in the longitudinal direction. Therefore, the heald must also have good tensile resistance. Therefore, the hardness of the rubber belt constituting the conveyor belt (JIS
A) is prepared to be about 50 or more and about 70 or less. The hardness of the rubber is closely related to the friction coefficient μ; a rubber with a hardness of 50 has a friction coefficient of about 1.5, and a rubber with a hardness of 70 has a friction coefficient of about 1.0. When the rubber hardness is less than 50, it is too soft and wrinkles occur in the heald due to the tensile action of the rotating shaft, and when the hardness is more than 70, it is too hard and a load torque is applied to each rotating shaft to make it adhere tightly to the circumferential surface of the rotating shaft. will come into play. Therefore, the hardness is preferably 60 for practical purposes, and in that case the surface ItJlp coefficient μ is about 1.2. However, the surface friction coefficient μ on the side where the rubber heald contacts the paper sheets to be conveyed is approximately 1.0.
The higher the value, the better; however, this will inevitably reduce the rubber hardness, which will prevent the formation of wrinkles and the decrease in tensile strength as described above. In order to avoid such inconvenience,
It is preferable to embed a fiber reinforcing layer in the rubber belt.

is 0.5 or less, preferably within the range of 0.5 to 0.3. If it is less than 0.3, slip will occur with the rotating shaft.

After that, the surface friction coefficient μ of the rubber belt is
A method is adopted in which the belt is immersed in a chlorine solution for a predetermined period of time so that the chlorine is in the range of 0.5 to 0.3, and then one side of the belt is polished to remove the chlorinated surface layer. By polishing this chlorinated surface, as mentioned earlier, the surface friction coefficient μ
One side of the rubber belt appears where the value is about 1.0 or more.

It is also possible to adopt a method in which a chlorine solution is applied to one side of a rubber belt made of a rubber composition formulated to have a concentration of 0 or less to chlorinate the surface layer.

The friction coefficient μ is preferably about 1.2, and the back surface is chlorinated so that the friction coefficient μ is within the range of 0.5 to 0.3. If it is placed on the side that contacts the shaft and the suction opening surface of the vacuum suction device and stretched between the rotating shafts, excessive torque will not be applied to the rotating shaft, and the suction force of the vacuum suction device will not be affected. While it can slide smoothly along the suction opening surface, it also has a good frictional effect on the paper sheets being conveyed on the belt, and in combination with the suction action of the vacuum suction device. The paper sheets can be transported normally without being deviated.

ベルトを製作できることが判る。[Example 4] Same as the comparative example in that a rubber belt was manufactured using a rubber composition containing 10 parts by weight of carbon blank, but a woven fabric of polyethylene terephthalate fibers was embedded in the rubber belt. A conveyor belt different from that of the comparative example was manufactured in that the elongation resistance in the longitudinal and lateral directions of the belt was reinforced. The belt of this example was used in a practical device (PPC copying machine) equipped with a rotating shaft with a tensioner.
As a result of a practical test in which the conveyor belt was stretched with an initial strain of 5%, the defects in the conveyor belt of the comparative example were completely eliminated and good copying results were obtained. This example shows that even if the rubber hardness is as low as possible in order to increase the coefficient of friction, it is sufficient to achieve the object of the present invention if the elongation resistance of the belt is strengthened by embedding a reinforcing layer in the belt. It can be seen that it is possible to manufacture a conveyor belt.
