Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a magnetic conveyor used in various structural industries involving the transportation of magnetic materials such as metal cans, plates, blocks, etc. The present invention relates to a twistable magnet conveyor that converts direction and top and bottom.

(Prior Art) In a magnetic conveyor of a type in which a belt travels on a magnetic transfer rail to transfer a magnetic substance adsorbed to the magnetic transfer rail via the belt, in order to change the top and bottom of a transferred object, There is used a type in which a step is provided between one belt conveyor and the other belt conveyor, and the step is inverted and turned along the guide rail when the transported object falls along the step.

In such a belt conveyor, an extra space is required to provide a step between the belt conveyors for reversing the conveyor, and the guides used for reversing the conveyor using the steps are used. However, there was a drawback that the size of was limited to a specific size. Further, it is a drawback that the twist angle of the conveyor cannot be adjusted once it has been set.

(Problem of the Invention) The object of the present invention is to provide a belt conveyor for conveying a magnetic material without the need to provide a step between the belt conveyors for reversing and turning the conveyed object, and to provide a guide for reversing or the like. It is unnecessary to be able to use it for the objects to be conveyed of various sizes, and to make it possible to adjust the reversal angle of the conveyor to an arbitrary angle.

(Means for Solving the Problems) The problems of the present invention are solved by the configurations described in the claims of utility model registration.

(Structure of Magnet Conveyor) According to FIGS. 1 to 4, the cross section is rectangular (FIG. 4).
The permanent magnet unit 1 is fixed to two opposing drive pulley guides 4 at one end thereof and to opposing tension pulley guides 6 at the other end thereof via a spacing member 7. The permanent magnet unit 1 comprises a permanent magnet 2 and a flexible yoke 3 surrounding the permanent magnet 2 and having a rectangular cross section (FIG. 4). An endless flexible belt guide 20 that can be twisted is disposed outside the flexible yoke 3. As shown in FIGS. 1 and 2, the permanent magnet unit 1 is formed by being twisted by 90 ° from one end to the other end. Can be twisted to any angle.

A motor 8 with a transmission is fixed to one outer surface of the drive pulley guide 4, and the shaft 8a of the motor 8 is also supported by the other drive pulley guide 4. The drive pulley 9 is attached to the motor shaft 8a.
Is fixed.

The drive pulley 9 has, for example, 14 grooves 9a. A control device 10 is still fixed to the drive pulley guide 4. Control device
10 is used for powering the motor 8 and for shifting the motor. Slots 6a are provided in both tension pulley guides 6 on the side of the tension pulley 11, and a shaft 12 having the tension pulley 11 mounted therein is rotatably supported in the slot 6a in a direction perpendicular to the axis. The tension pulley 11 supported by the shaft 12 is rotatable. The tension pulley 11 has the same number of grooves 11a as the grooves 9a of the drive pulley 9.

A plurality of round belts 13 (belts of various cross sections other than round belts can be used) 13 are wound around the drive pulley 9 and the tension pulley 11. Round belt 13
Two tension pulley guides 6 for adjusting the tension of the
A bracket 14 is fixed to the outer surface of the bracket 14, a hole 14a is provided in the bracket 14, the threaded portion 15b at one end of the threaded rod 15 is freely rotatably passed through the hole 14a, and the other end of the threaded rod 15 is also provided. The threaded portion 15a of the shaft 12 is screwable into the female threaded portion 12a of the shaft 12, whereby the threaded rod 15 has a threaded portion 15b at one end and a double nut 1a.
It is fixed to the bracket 14 by 6, 16.

(Torsion adjustment mechanism) The frame 21 is attached to the drive pulley guide 4,
The frame 21 extends along the wound belt 13 and is bent at the other end in the longitudinal direction of the tension pulley 11.
The frame 21 may be provided with a suitable reinforcing material in addition to the shape shown. On the other hand, surrounding the tension pulley guide 6,
A U-shaped bracket 22 is provided that is axially supported by the shaft 12 of the tension pulley 11, a shaft 25 is passed through the center of the bracket 22, and the shaft 25 includes a flange 25a and the shaft 25
The end of is a shaft part 25b of rectangular cross section,
Is engaged with the bracket 22 so as to be movable in the axial direction and non-rotatable with respect to the bracket 22. A spring case 23 is fixed to the frame 21, and a compression spring 24 is inserted between the bottom of the spring case 23 and a flange 25a of a shaft 25 that is passed through the spring case 23 in the spring case 23. 24 is axis 25
Is urged to the left in FIG. A boss 26 is fixedly provided at the end of the range of the shaft 25 protruding outward of the spring case 23.
The pin 27 fixed to the inner end of 26 is engaged in the clip hole 23a on the surface of the right end of the spring case 23, and can be disengaged against the spring force of the compression spring 24. The boss 26 is provided with a hole 26a penetrating laterally, and a handle 28 for adjusting the twist angle of the permanent magnet unit 1 and thus the belt guide 20 (second
Figure) can be threaded.

A round belt is passed through the drive pulley 9 by the rotation of the motor shaft 8a.
13 is driven and the tension pulley 11 rotates.

The round belt 13 runs in close contact with the groove 20a of the belt guide 20 on the permanent magnet unit 1. As a result, a magnetic material, such as a can, a plate or a block, placed on the round belt 13 is guided by a flexible belt guide on the permanent magnet unit 1 by the action of a magnet.
It can be conveyed along the surface of 20 from the motor side to the tension pulley side or vice versa.

Since the permanent magnet unit 1 whose cross section is shown in FIG. 4 is twisted by a phase angle of 90 ° from one end to the other end (FIGS. 1 and 2), it is conveyed by the round belt 13. The magnetic material is turned by 90 °. However, the permanent magnet unit 1 can be adjusted to an arbitrary twist angle by a twist adjusting mechanism described later. According to the twisting angle of the permanent magnet unit 1, for example, if the twisting angle is 180 °, 180 °, 13
If it is 5 °, the magnetic substance will be turned by 135 ° during conveyance and transferred to the next conveyer conveyor or supplied to various processing machines. Instead of the round belt 13, an open belt can also be used. The twistable magnet conveyor according to the present invention is constructed as follows in order to be able to reverse and convey the conveyed object by the belt. The angle of reversal is adjusted by operating an operating handle (not shown) to rotate the boss 26, and thus the shaft 25, which engages with the operating handle, thereby rotating the bracket 22 and thereby the square hole 22a and the shaft 2.
By rotating the tension pulley guide 6 through the engaging portion with the rectangular portion 25b of 5, the twist angle between the drive pulley guide 4 and the tension pulley guide 6, that is, the reversal angle can be adjusted. At this time, the shaft 25 is pulled against the spring 24, and the click pin 27 is engaged in the click hole 23a at a desired position, so that the twist angle of the conveyor is determined by the reversal angle.

(Effect of the Invention) According to the present invention, it is not necessary to provide a step during the conveyance by the conveyor that continuously conveys the conveyed object, and the conveyed object can be turned by an arbitrary angle during the conveyance by one conveyor. The guide for the transported object, which is conventionally required for turning, is unnecessary, and the transported object of any size can be turned and transported by one conveyor at any reversal angle.
