Description of the invention: [Technical field to which the invention belongs] The present invention relates to a conveyor capable of placing a moving object and moving it. [Prior Art] In the past, conveyors such as roller conveyors and belt conveyors have been used for conveying objects. These carousels use the power of a motor or the like to rotate the rollers or move the endless belt to carry the objects carried on the rollers and belts. When an endless belt conveyor is used, it usually has a structure in which a rotating body provided on both sides is rotated by a motor. The rotating body of the belt conveyor and the rollers of the roller conveyor are supported by a shaft. For example, the roller conveyor 100 shown in FIG. 4 and FIG. 5 is a person who carries a transported object 80 on a plurality of rollers 108a. Specifically, three rollers 108a are arranged on each shaft 2 to form a group of rollers 108, and the rollers 108 of this group are arranged at a predetermined interval in the conveying direction. The roller conveyor 100 is provided with a motor 10, and the motor 110 and the shaft 112 are connected via a belt 111, so that the shaft 112 can be rotated to drive the roller 10 center. In addition, a part of the shaft 112 of the whole type is connected to the motor 11 to drive all or a part of the roller 108a. When the roller conveyor 100 is used, the roller 108a is rotated in the same direction, and is used for conveying the conveyance object 80 placed on the conveying surface of the roller 108 & In addition to the arrangement of the roller 108a in the width direction, a roller 108a having a longer width may be used instead. 98667.doc 200535073 In addition, in the belt conveyor 120 shown in FIG. 6, an endless belt 115 is mounted on a roller 108 connected by a motor no and a belt 111. Further, by operating the motor 110 and rotating the roller 108, the endless belt 115 is moved in the conveying direction. In use, it is used to carry the transported object 80 on the endless belt U5. In addition to the above-mentioned connection between the roller 108a and the motor 110, gears, magnets, and seal rings may be used in addition to the belt 1 ^. In addition, the roller 108a may be provided with the function of the motor 110, and the roller 108a may be used to drive the driver. '[Summary of the Invention] In the case where a conveyed object is conveyed by the conveyors 100, 102, etc., when the width of the conveyed object 80 is larger than the width of the conveyors 100 and 120, the conveyed object 80 will fall easily. It cannot be carried. For this reason, it is necessary to increase the width of the set of rollers 108 and the width of the endless belt 115. However, if the width of the arrangement of the rollers 108 and the width of the endless belt 115 are increased, the shaft 112 must also be lengthened. This shaft 12 is usually held • It can be rotated near both ends. Therefore, the longer the shaft 12 is, the easier it is to deflection even with the same weight. Furthermore, since the width is increased, the carried object 80 is also apt to be heavier, and therefore, the shaft 112 is particularly prone to flex. In addition, in order to reduce this deflection, the diameter of the shaft 1 丨 2 is sometimes increased, but in this case, the deflection caused by the weight of the shaft 112 itself must also be considered. Furthermore, in order to cope with deflection, it may be necessary to apply special processing to the shaft, which is very difficult to design. Furthermore, once the conveyors 100 and 120 are manufactured, the widths of the conveyors 100 and 120 cannot be changed any more, and it is necessary to re-produce them. In addition, in the case where 98667.doc 200535073 is to be used to transport objects 80 with different widths by the same conveyor 100, 120, it is necessary to produce the objects with the maximum width of the object 80. In addition, in this case, in the case of conveying the conveyance 80 with a small width, compared with the conveyance 80 in the conveyance, the operator who checks your teeth next to you will move away from the conveyance 80, making The work and the like of the transported object 80 are difficult to perform. Therefore, an object of the present invention is to provide a conveyor having a high versatility and a support shaft that is not easily deflected. In view of the above, the present invention for achieving the above-mentioned object is a conveyor, which is characterized in that the driving body is driven by the upper part in the conveying direction and is not disposed along the conveying direction; and the free support body is provided in the driving body. Both sides are set along the conveying direction; the free support body can rotate freely while supporting the conveyed object, and the upper part is set to rotate in the conveying direction, and the conveying surface is formed by the upper part of the free support body and the upper part of the driving body, Transport the transported object on the transport surface in the transport direction. According to the present invention, since the driving body driven in the conveying direction and the free supporting bodies provided on both sides of the driving body and provided with the upper part rotating in the conveying direction constitute the conveying surface, the conveyed objects can be conveyed. Therefore, by supporting the widthwise end of the conveyed object with a free support body, the width of the members constituting the driving body can be shortened, the length of the supported shaft, etc. can be shortened and the deflection can be reduced. In addition, according to the width of the conveyed object, the width of the conveyor can be changed by moving or adding a free support body, and the same driving body can be used to form a conveyor of the general purpose station. In addition to the above-mentioned structure, the free supporting body can be moved in a vertical direction with respect to the conveying direction. 98667.doc 200535073 In this case, 'the free support body can be moved in a vertical direction with respect to the conveying direction. Therefore, # p, 4 is easy to change the width of the conveyor and it is easy to make it correspond to the width of the conveyed object. status. The transport surface formed by the upper part of the free supporting body and the upper part of the driving body may be a flat shape that expands in the horizontal direction. In this case, the 'conveying surface has a flat shape which is enlarged in the horizontal direction, and therefore, it is difficult for the conveyed object to fall. In addition, the free supporting body may be rotated around an axis perpendicular to the conveying direction. In this case, the 'free supporting body' will rotate around the axis perpendicular to the conveying direction as the center of the & 'easy support of the conveyed object, and the free support's rotation will become smooth by the movement of the conveyed object. As such a driving body, a roller or an endless belt can be used, and as a free supporting body, a roller can be used. The carousel according to the present invention is highly versatile and the shaft is not easily bent. [Embodiment] The following 'will further describe specific embodiments of the present invention. Figure 1 is a front view of a conveyor in an embodiment of the invention. Figures 2 and 3 are part of a plan view of a conveyor in an embodiment of the present invention. The conveyor 1 according to the first embodiment of the present invention is shown in FIG. On the upper part of the driving part 10, there is a roller family 'free support material 11' which is a donkey moving body. On the upper part, a roller 40a as a free support body is provided. The roller 20a and the roller 40a are formed. Carrying surface 70. In addition, the transported object 80 can be carried on the transport surface 70. ° 98667.doc 200535073 The roller 20a and the roller 40a are cylindrical, disc-shaped, etc., and can rotate around the center of the shaft. A set of roller groups 20 formed by two rollers 20a is formed on the driving body 10, and a set of roller groups 20 are arranged side by side in the conveying direction. The two rollers 20a are arranged coaxially, and a shaft 21 is provided at the center of these. The shaft 21 and the two rollers 20a are fixed, and by the rotation of the shaft 21, the two rollers 20a will rotate in the same direction. The shaft 21 is perpendicular to the conveyance direction, and the roller 20a is arranged so that the upper portion can rotate in a direction that becomes the conveyance direction. Therefore, when conveying the conveyance 80, the driving force can be transmitted from two places, and the conveyance can be carried out with good balance. In addition, the shaft 21 is rotatably supported at both ends by support portions 22 provided on the bearing portion 25, and can rotate while supporting the roller 20a and the load 80 carried on the roller 20a. The shaft 21 fixed with the two rollers 20a is arranged side by side in the conveying direction as shown in FIG. 2. The shaft 21 is connected to the motor 3 β through a belt 23 and the shaft 21 is rotated by rotating the motor 30. The roller 20a is rotated to drive it. In addition, the rotation of the shaft 21 is a co-rotator. Various methods can be used to connect the motor 30 to each shaft 21. For example, a motor 30 may be provided corresponding to each axis 2 and a plurality of belts 23 may be connected to the motor%. Furthermore, the shaft 21 and other shafts 21 connected to the motor 30 may be connected by a belt 23. It is also possible to drive all the rollers 2Ga. In addition, if it is possible to carry and carry the object 80, only a part of the rollers 20a can be driven, and the other rollers 20a can be rotated freely. The connecting parts of the shaft 21 and the like use a rotary 98667.doc -10- 200535073 pulley, etc., so that the rotation speed and torque can be adjusted. • The free support section u is approximately the same length as the drive section 1G, and is set to extend in the direction of the 纟 transport, and is provided at two places on both sides of the drive ㈣. As a result, a state is provided in which the drive 10 is arranged between the free support portions u provided at two places. The free support portion 11 includes a roller roller 41, a shaft 41, and a support portion 42. As shown in FIGS. 1 and 2, the roller 40a is supported by a shaft 41 that is cut and supported. Spin. A plurality of rollers 40a of each of the free supporting portions 11 and 1 are arranged side by side in the transport direction. The roller 40a is rotatably supported by a shaft 41. The direction of the shaft 41 is parallel to the shaft 21 of the driving body 10, and is perpendicular to the conveying direction, and is parallel to the conveying surface 70. Therefore, by rotating the roller 40a, the upper portion of the roller 40a can be moved in the conveying direction. In addition, the arrangement of the rollers 20a of the driving body 10 and the arrangement of the rollers φ4a of the free support portion 丨 need not be arranged side by side as long as they are arranged to extend in the conveying direction. For example, as shown in FIG. 3, the arrangement of the rollers 40a of the free supporting portion 丨 can be formed in a zigzag shape. In this way, when the arrangement of the rollers 20 and 40a is formed in a zigzag shape, the adjacent rollers 2a and 40a are not easy to contact, and the interval in the conveying direction can be narrowed. As shown in FIG. 1, the positions of the upper part of the roller 20 a of the driving part 10 and the upper part of the roller 40 a of the free support part 11 are at about the same height, and the upper part of the roller 20 a and the roller 40 a The conveying surface 70 formed on the upper portion is a flat surface extending in the horizontal direction. 98667.doc 200535073 Therefore, as shown in FIG. 1, when conveying the conveyed object 80 having a flat shape on the rear side of the bottom portion, it can stably convey. The support portion 25 of the portion 10 and the support portion 42 of the free support portion 丨 are provided on a table not shown in the figure. In addition, the support portion 42 of the free support portion U and the table not shown in the figure can be positioned relative to the conveying direction. Moving in the vertical direction can change the distance between the drive section 10 and the free support section 11. The change in the distance between the drive section 10 and the free support section 丨 丨 is perpendicular to the conveying direction. The length of the width. The method for transporting the transported object 80 by the container 1. First, 'the free support portion u is moved according to the width of the transported object 80. Specifically, σ' is placed inside the transported object 80 more than the widthwise end of the transported object 80, The conveyed object 80 is supported by the free support portion 11. This allows the conveyed object 80 to be stabilized when it is placed on the conveying surface 70 composed of the roller 20a and the roller 40a. In the conveyor 1, the driving portion 1 〇The free supporting portions 〖丨 '' arranged on both sides However, the position of the driving portion 丨 〇 is arranged near the middle of the free supporting portions i 丄 on both sides, so that the conveyed objects can be stably conveyed. Therefore, This is preferable. Next, the transported object 80 is placed on the transported surface 70. At this time, the transported object 80 will be in contact with the roller 20a. In addition, the transported surface 70 has a horizontal shape with almost no tilt, Therefore, the transported object 80 does not fall. When the motor is operated, the driving force is transmitted to the roller 20a via the belt 23 and the shaft 21, and therefore, the shaft 21 and the roller 20a are rotated. This rotation causes the upper portion of the roller 20a to move in the conveying direction. 98667.doc -12-2005350 73 When the roller 20a rotates at the upper part, the conveyed object 80 which is conveyed to the conveying direction _ will move toward the conveyance due to friction to transmit the driving force. When the conveyed object 80 moves, it will move away from the driving force to convey the moving roller. 20a is plural in the conveying direction, and the roller 20a, which comes into contact with it, is conveyed to one of the two transport surfaces 70 in the conveying direction to the other. During this conveying process, the conveying object 8 The end in the width direction is supported by the roller 40a of the self-supporting portion 11. Therefore, #J knife puts the load of the conveying object 80 to prevent the roller 2 () a of the driving portion H) from receiving an excessive load. . In addition, since the "roller 40a rotates" at this time, the friction between the roller and the conveyed object can be reduced, and the conveyance can be performed even with a small driving force. In addition, the interval in the transport direction between the rollers 20a and the interval in the transport direction between the rollers 20a can be set according to the size of the transported object 80. At this time, it is necessary to set the state in which the conveyance object 80 can maintain contact with any one of the rollers 20a. According to the above-mentioned embodiment, one free support portion U is provided on each side of the driving portion 10, but a plurality of free support portions U may be provided on each side.
