  However, according to the above-described conventional configuration, the V belt pulley is provided facing all the rollers from below, so that the structure is complicated and the whole is expensive. Especially for a straight roller, the structure becomes more complicated by inclining the pulley shaft of the V-belt pulley.

  Accordingly, the invention according to claim 1 of the present invention is a conveyor in which a common endless flat belt is disposed over the linear path portion and the curved path portion, but the structure can be simplified and the whole can be made inexpensive. The purpose is to provide equipment.

  In order to achieve the above-mentioned object, the conveyor equipment according to claim 1 of the present invention has a linear path portion and a curved path portion by disposing a group of rollers freely on the conveyor frame. Conveyor equipment in which a path is formed, and the driving means of the roller group is configured by disposing a common endless flat belt in each path part along the transport path and providing a driving unit for the endless flat belt. The endless flat belt is configured to freely contact the roller group from the lower side with the belt thickness direction being the vertical direction in the linear path portion, and to the roller group with the belt width direction being the vertical direction in the curved path portion. It is configured to be able to come into contact with a rotation passive part of a group of transmission rotors provided facing each other, and the rotation drive part of these transmission rotors is configured to be able to contact an opposing roller. so That.

  Therefore, according to the first aspect of the present invention, in the conveying path, the conveying force can be obtained by rotating the common endless flat belt by driving the driving unit in the driving means. That is, in the linear path portion, the roller group can be driven by bringing the endless flat belt whose belt thickness direction is the vertical direction into contact with the roller group from below. In the curved path section, the transmission rotating body group is driven to rotate by an endless flat belt whose belt width direction is the vertical direction, and the rotation passive section of the transmission rotating body is brought into contact with the roller to drive the roller group. Can do.

  According to a second aspect of the present invention, there is provided the conveyor apparatus according to the first aspect, wherein the transmission rotating body is arranged to face the roller from below, and has a vertical axis on the conveyor frame side. A rotationally passive portion is formed by a laterally circumferential surface centered on the longitudinal axis thereof, and a ring-shaped rotational drive portion centered on the longitudinal axis is provided on the upward surface. The portion of the rotational drive unit that has reached a predetermined location is configured to be able to abut against the opposed roller from below, and is provided with an urging means for urging and abutting. .

  Therefore, according to the second aspect of the present invention, the transmission rotating body group is driven and rotated around the longitudinal axis by the endless flat belt, and the rotation driving unit is rotated integrally with the transmission rotating body. At this time, the portion of the rotational drive unit that reaches a predetermined location is in contact with the opposed roller from below, so that these roller groups can be driven to rotate, and the curved path portion can be brought into a drive conveyance state. At that time, the urging means urges the transmission rotor side upward so that the roller can be abutted from below with respect to the rotation drive unit with a constant abutment force (abutment pressure).

  In the conveyor apparatus according to claim 3 of the present invention, in the configuration according to claim 1 or 2, the curved path portion has a small diameter on the small-diameter side in the curve and a diameter on the large-diameter side in the curve. A large conical roller group is arranged, and the rotational drive part of the transmission rotating body is configured to be able to contact a portion where the diameter of the conical roller group is small.

  Therefore, according to the third aspect of the present invention, in the curved path portion, the rotational driving portion of the transmission rotating body is placed below the portion where the diameter of the conical roller group is small, that is, the same diameter as the diameter of the straight roller. The two roller portions can be rotated while adjusting the direction of the object to be conveyed in the curved path portion due to the change in the peripheral speed of the conical roller group. In this case, the objects to be conveyed can be continuously conveyed at the same conveyance speed.

  Furthermore, in the conveyor equipment according to claim 4 of the present invention, in the configuration according to claim 1 or 2, the curved path portion has a small diameter on the small diameter side in the curve and a diameter on the large diameter side in the curve. When a large conical roller group is arranged and the conveyance path has two types of curved path sections with different curve directions on the left and right, the endless flat belt moves in the conveyor width direction between these curved path sections. In any of the two types of curved path portions, the rotation driving portion of the transmission rotating body is configured to be able to contact the small diameter portion of the conical roller group. It is.

  Therefore, according to the invention of claim 4, by incorporating the conveyor width direction moving part, the rotation drive part of the transmission rotating body is provided in the part where the diameter of the conical roller group is small in any of the two kinds of curved path parts. The conical rollers can be rotated at the same rotation speed by contacting them from below, so that both curvilinear shapes are adjusted while adjusting the direction of the object to be conveyed in both curvilinear path portions by the change in the peripheral speed of the conical roller group. In the path portion or the like, the objects to be conveyed can be continuously conveyed at the same conveyance speed.

  According to the first aspect of the present invention described above, in the conveying path, the driving unit in the driving means can be driven to rotate the common endless flat belt to obtain the conveying force. That is, in the linear path portion, the endless flat belt whose belt thickness direction is the vertical direction is brought into contact with the roller group from below, so that the roller group can be driven and the driving force transmitted by the endless flat belt is always transmitted. Thus, the roller group can be driven and rotated at a predetermined rotational speed. In the curved path section, the transmission rotating body group is driven to rotate by an endless flat belt whose belt width direction is the vertical direction, and the rotation passive section of the transmission rotating body is brought into contact with the roller to drive the roller group. Thus, the transmission of the driving force by the endless flat belt can always be stably performed via the transmission rotating body that bends and deforms without difficulty, and the roller group can be driven and rotated at a predetermined rotational speed.

  According to such a conveyor facility, a transmission rotating body is provided only facing the roller group of the curved path portion, while a common endless flat belt is disposed across the linear path portion and the curved path portion. By providing the structure, the structure can be simplified and the whole can be made inexpensive, and the driving force can be transmitted smoothly to the roller group at all times.

  According to the second aspect of the present invention, the transmission rotating body group can be driven and rotated around the longitudinal axis by the endless flat belt, and the rotation driving unit can be rotated integrally with the transmission rotating body. At this time, the portion of the rotational drive unit that has reached a predetermined location is in contact with the opposing roller from below, so that these roller groups can be driven to rotate, and the curved path portion can be brought into a drive conveyance state. At that time, by urging and energizing the transmission rotator side by the urging means, it is possible to perform the abutting from the lower side with respect to the rotation driving unit to the roller with a constant abutting force (abutting pressure), As a result, the rotation of the roller group can always be carried out suitably and stably.

  According to the third aspect of the present invention described above, in the curved path portion, the rotational driving of the transmission rotating body is performed in a portion where the diameter of the conical roller group is small, that is, a portion having the same diameter as that of the straight roller. The roller group can be rotated at the same rotation speed by contacting the part from below, and both of them can be adjusted while adjusting the direction of the conveyed object in the curved path part due to the change in the peripheral speed of the conical roller group. In the path portion, the object to be conveyed can be continuously conveyed at the same conveyance speed.

  Further, according to the fourth aspect of the present invention described above, the rotation of the transmission rotating body is rotated to a portion where the diameter of the conical roller group is small in either of the two curved path portions by incorporating the conveyor width direction moving portion. The conical roller can be rotated at the same rotation speed by bringing the drive unit into contact with the lower side, so that both the curvilinear path portions adjust the direction of the object to be conveyed by changing the peripheral speed of the conical roller group. In a curved path portion or the like, the object to be transported can be continuously transported at the same transport speed.
