Description

[Detailed description of the invention] (Field of industrial application) The present invention is applied to a magnetic conveyor used in various manufacturing industries involving the conveyance of magnetic materials such as metal cans, plates, blocks, etc. Concerning reversing magnetic conveyors that change direction, top and bottom.

(Prior Art) In a magnetic belt conveyor in which a belt runs on a magnetic rail and conveys a magnetic material that is attracted to the magnetic rail via the belt, there is a method for changing the top, bottom, and conveying direction of the conveyed object. A type is used in which a step is provided between one belt conveyor and the other belt conveyor, and when the conveyed object falls down the step, it is reversed and turned around along a guide rail.

In such a belt conveyor, an extra space is required to provide a step between the belt conveyors for reversing the conveyed object, and the guide used for reversing using a head is also disadvantageous. The disadvantage is that the size of the carrier is limited to a specific size.

There is also a type of reversing belt conveyor twisted by 180° (Japanese Patent Application Laid-Open No. 52-472665).
In this case, the disadvantage is that the flat belt having the magnetic material on its surface is worn out and the magnetic material and the flat belt itself are damaged due to repeated twisting.

(Problems of the invention) The present invention eliminates the need for providing a step between the belt conveyors for reversing or turning the conveyed object, and does not require a guide for guiding the reversal. Another object of the present invention is to provide a reversing magnetic conveyor that can be used for conveyed objects of various sizes without excessive twisting of the belt conveyor and without damaging the magnetic material.

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

(Example) The present invention will be explained based on the illustrated embodiment.

In FIGS. 1 and 2, a permanent magnet unit 1 having a rectangular cross section (see FIG. 3) has two opposing drive pulley guides 4 at one end.
and the other end thereof is fixed to two opposing tension pulley guides 6 via spacing members 5 and 7. The permanent magnet unit 1 consists of a permanent magnet 2 and a casing 3 surrounding it (FIG. 3). 1st
As shown in Fig. 2, the permanent magnet unit 1
is twisted 90° from one end to the other in a left-handed (or right-handed) direction; It can be formed to have any helix angle.

A motor 8 with a transmission is fixed to the outer surface of one of the drive pulley guides 4, and a shaft 8a of the motor 8 is also supported by the other drive pulley guide 4. A drive pulley 9 is fixed to the motor shaft 8a. Corresponding to the left-handed twist of the permanent magnet unit 1, the motor shaft 8a on the axis of the drive pulley 9 and the shaft 12 of the tension pulley 11 are also twisted in the left-handed direction like the permanent magnet unit 1. It is twisted clockwise to the same helix angle as the permanent magnet unit 1 when looking from the tension pulley 11 to the drive pulley 9. On the other hand, if the permanent magnet unit 1 is twisted in a right-handed direction, the motor shaft 8a on the axis of the drive pulley 9 corresponds to this.
and the shaft 12 of the tension pulley 11 is also twisted counterclockwise in a right-handed direction and at the same helix angle as the helix angle of the permanent magnet unit 1 when looking from the tension pulley 11 toward the drive pulley 9. ing.

The reversing magnetic conveyor according to the present invention works as follows.

The drive pulley 9 has, for example, 14 grooves 9a.
A control device 10 is also fixed to the drive pulley guide 4. A control device 10 is used for power supplying the motor 8 and for changing the speed of the motor. A slot is provided in both tension pulley guides 6, 6, and the tension pulley 11 is inserted into the slot.
A shaft 12 fitted into the slot is supported in the slot so as to be adjustable in a direction perpendicular to the axis, and the tension pulley 11 is rotatable while being supported on the shaft 12. The tension pulley 11 has the same number of grooves 11a as the grooves 9a of the drive pulley 9.

Fourteen endless round belts (hereinafter simply referred to as "round belts") 13 are wound around the drive pulley 9 and the tension pulley 11. A bracket 14 is fixed to the outer surface of the two tension pulley guides 6 in order to adjust the tension of the round bet 13. This bracket 14 is provided with a male thread, and a threaded rod 15 is passed through this hole. The other end is fixed to the shaft 12 so as to be rotatable and immovable in the axial direction. Nut 16 on threaded rod 15
are fitted.

The reversing magnetic conveyor works as follows.

The rotation of the motor shaft 8a drives the round belt 13 via the drive pulley 9, and the tension pulley 11 rotates on the shaft 12.

A round belt 13 runs closely over the permanent magnet unit 1. As a result, a magnetic body placed on the round belt 13, such as a can, plate, block, etc., is attracted onto the surface of the permanent magnet unit 1 by the action of the magnet, and the round belt 13 moves the magnetic body along the surface from the motor side. It can be conveyed to the shock pulley side or in the opposite direction.

In the illustrated case, the permanent magnet unit 1 is twisted from one end to the other in a left-handed or right-handed direction by a phase angle of 90°, so the magnetic material conveyed by the round belt 13 is similarly twisted in a left-handed or right-handed direction. in the direction of the screw
It is turned 90°. Depending on the helix angle of the permanent magnet unit 1, that is, if the helix angle is left-handed or right-handed and the helix angle is 180 degrees or less, for example, if it is 180 degrees, it will be 180 degrees, if it is 135 degrees, it will be 135 degrees. will be diverted and transferred to the next conveyor or fed to various processing machines.

(Effects of the invention) According to the invention, there is no need to provide a step between the conveyors that convey the objects to be conveyed, and the objects to be conveyed can be rotated 180 degrees in the right-handed or left-handed direction while being conveyed by one conveyor. It can be turned by any angle less than or equal to

According to the present invention, there is no need for a guide for conveyed objects, which was conventionally required for turning, and objects of any size can be converted and conveyed by one conveyor.

The reversing magnetic conveyor of the present invention is convenient because it can be easily connected to an existing conveying device. In the reversing magnetic conveyor according to the present invention, there is no risk of wear or damage to the magnetic body itself, and there is no fatigue damage to the belt conveyor due to repeated twisting.
