Description

  The present invention relates to a roller-type conveyance device, and more particularly to a conveyance device in which a conveyance roller is driven and rotated by a non-contact type power transmission method using magnetic force.

2. Description of the Related Art A conveyance device in which conveyance rollers are attached in parallel at a constant pitch between a pair of front and rear frames, and conveys an object to be conveyed by driving and rotating the conveyance rollers is used in various physical distribution conveyances. The conveying device is commonly called a drive roller conveyor, and the following method is generally adopted as a method for driving the conveying roller.
(1) Round belt drive system A system that rotates a countershaft as a drive source and transmits drive force from the countershaft to each conveying roller via a round belt.
(2) Chain drive system A system in which the sprocket attached to the transport roller is directly driven by the chain.
(3) Flat belt (or V-belt) drive system A system in which a flat belt (or V-belt) runs on the lower surface of the conveying roller and rotates the roller by its frictional force.

However, each of the drive systems described above is a contact-type drive system in which the shaft, chain, or belt to be driven is brought into contact and driven and rotated by the contact friction force.
Accordingly, there have been problems such as belt wear, dust generation, and generation of noise due to contact.
In order to solve the above problems, a roller conveyor using a non-contact type drive system using magnetic force has been developed and proposed.

  The roller conveyor of the non-contact type drive system using the magnetic force is such that the conveying roller is rotatably supported between the pair of front and rear frames via a bearing, and the end of one shaft protruding outside the frame Next, a driven magnetic wheel in which N and S poles of a permanent magnet are alternately magnetized is fixed, and a driving magnetic wheel in which the N and S poles of the permanent magnet are spirally magnetized below the driven magnetic wheel. The driven magnetic wheel is rotated by driving the motor and the drive magnetic wheel is rotated by a motor in a non-contact manner, and the transport roller is rotated (see, for example, Patent Document 1).

However, as shown in Patent Document 1, the driven magnetic wheel that transmits the rotational force to the conveyance roller is disposed so as to be exposed outside in the axial direction of the roller length (effective roller length) that forms the conveyance surface. Similar to the mold drive system, there is a problem that the effective width of the roller used for conveyance is narrower than the width of the conveyor (outside width of the front and rear frames).
In addition, if the driven magnetic wheel is exposed, it may become dirty or rusted, which may interfere with power transmission.

FIGS. 5 and 6 are roller-type conveying devices in which the frame is formed of a circular cylindrical frame in plan view, and further equipped with a rotating mechanism for horizontally turning the cylindrical frame. The conveyance roller B has the same configuration except that there is a dimensional difference in the roller length.
As in the first embodiment, the frame A ′ is made of a metal material or a synthetic resin into a cylindrical frame 11 having a circular shape in plan view, and has the same configuration as that shown in the first embodiment inside the cylindrical frame 11. The conveying rollers B are arranged in parallel by gradually changing the roller length from the position (on the diameter line) passing through the approximate center of the cylindrical frame 11 toward the peripheral wall direction of the cylindrical frame 11 perpendicular thereto. It is configured.
The shaft support of the transport roller B with respect to the cylinder frame 11 is attached to the bearing frame 11 ′ attached to the inner side of the tube frame 11 while the support shaft 5 constituting the transport roller B is prevented from rotating. The shape body 2 is configured to rotate.

  As in the first embodiment, the ring 3 of the permanent magnet built in the conveyance roller B that is pivotally supported in parallel within the cylinder frame 11 is straight when the conveyance roller B is attached to the cylinder frame 11. It should be placed on the line.

As described above, the cylindrical frame 11 in which the conveying rollers B are arranged in parallel is connected to the upper part of the cylindrical body 12 to which the power transmission mechanism C ′ is attached, and the cylindrical frame 11 is rotated by the rotation of the driving motor 8 of the power transmission mechanism C ′. The inner conveying roller B is configured to drive and rotate without contact.
Since the power transmission mechanism C ′ has the same configuration as that of the power transmission mechanism C shown in the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.
That is, the bearings 14 and 14 ′ are fixed upright on the base plate 13, and the drive magnetic wheel 6 is rotatably supported across the bearings 14 and 14 ′.

And, since the transfer device is circular and swivels around its center as the center of rotation, there is no change in the outer shape before and after the horizontal swivel, so the transfer roller of the conveyor arranged around Can be arranged at a position close to the outer peripheral surface of the circular transfer device without contact. Thereby, transfer can be performed stably.

FIG. 9 shows a mode in which the driving motor 8 ′ in the conveying device E provided with the rotating mechanism D is arranged outside the cylinder 12, and the driving motor 8 ′ mounts a rotary actuator constituting the rotating mechanism D. A hanging mount is attached to the lower surface of the mounting base 20 via a mounting member 21, and a drive shaft 23 is connected to the output shaft of the drive motor 8 ′ via a coupling 22.
