Abstract

PURPOSE:To improve an efficiency without damaging paint on the outercircumference of magnetic material, in a carrying device for magnetic material such as film patrone having non-magnetic material at one end, by constructing such that the work in the second row on a stock conveyor is held through pushing then the work in the first row is transferred while magnetically adsorbing laterally. CONSTITUTION:When transferring, a magnet arm 21 is advanced/retracted to magnetically adsorb a film patrone 3b in the frontmost row on a stock conveyor 1 and transfer onto a discharge conveyor 19. Here, the film patrone 3a in the second row is held by holding unit 9 through pushing. After transferring, the holding unit 9 is released to advance the conveyor 1 by a single row. With such arrangement, it can be transferred without damaging the painted outercircumferential face of magnetic material.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a film cartridge for camera film, etc.
The present invention relates to a magnetic material transfer device that transfers a substantially cylindrical magnetic material having a non-magnetic material at one end to the next step in a fixed amount in a manufacturing process or the like.

[Background of the invention]

Conventionally, as a transfer device for film cartridges, a container in which a large number of film cartridges are accumulated is inverted, dropped onto a belt conveyor, and conveyed by the conveyor (for example, Japanese Patent Application Laid-Open No. 57-64729). Transfer devices include vibration transfer using a vibrating feeder, chucking transfer using a robot, and the like.

In either case, film cartridges can be sequentially transferred from a predetermined stock section to a discharge section.

However, in the conventional apparatus, there is a risk that the film cartridges come into contact with each other during transport and damage the coated outer periphery of the film cartridges. For this reason, in the case of recent film cartridges that have patterns such as film sensitivity printed on their outer peripheral surfaces, there is a problem in that the patterns are damaged and the functions of the patterns are inhibited. Further, in the conventional transfer device, the film cartridge is sent in an irregular posture, which requires a large transfer space, which causes a slow working speed.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and provides a method for transferring a magnetic material that can be efficiently transported without damaging the painted surface of the outer periphery of a substantially cylindrical magnetic material that partially has a non-magnetic material. The purpose is to propose a device.

[Summary of the invention]

In order to achieve the above object, the present invention arranges and places substantially cylindrical magnetic bodies on a stock conveyor in a pre-process, presses and holds at least the second row from the front row, and uses an electromagnetic attraction type magnetic body. A magnetic arm magnetically attracts the magnetic material in the front row on the stock conveyor and transfers it onto the discharge conveyor.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a magnetic material transfer device according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram showing the entire device.

The stock conveyor 1 is intermittently moved forward in the direction of arrow a by a predetermined distance by a control device (not shown). On this stock conveyor 1, a large number of substantially cylindrical magnetic bodies, for example, film cartridges 3, are placed in a plurality of rows in a pre-processing process. As shown in FIG. 2, a non-magnetic protrusion 5, which is part of the winding shaft, protrudes from the center of the film cartridge 3. Furthermore, a pattern 7 for displaying film sensitivity, etc. is formed on a part of the outer periphery of the film cartridge 3, and as described above, this pattern 7 is designed to avoid damage due to contact or the like.

A holding device 9 is provided above the stock conveyor 1 for holding objects to be transferred during transfer.

This holding device 9 presses and holds the film cartridge 3a in the second row from the front row from above.
A lower end 13a of the lifting rod 13 hanging from the lower end 13a is pressed downward by a compression coil spring 15. Note that the lifting rod 13 is driven up and down by a cylinder device which will be described later. Cushioning material 1 such as rubber is attached to the lower end of this lifting rod 13.
7 is attached to press the projecting piece 5 of the film winding shaft protruding from the upper end of the film cartridge 3a.

The cylinder device that drives the lifting rod 13 is set by a control device (not shown) to give an ascending command to the lifting rod 13 during the feeding operation of the stock conveyor 1, and to give a descending command to the lifting rod 13 at the stop position shown in FIG.

On the other hand, in FIG. 1, reference numeral 19 denotes a discharge conveyor, which is disposed at a predetermined distance from the stock conveyor 1 in a direction perpendicular to the transport direction of the stock conveyor (perpendicular to the plane of the paper).

A magnet arm 21 is provided above the discharge conveyor 19 as a transfer means for transferring the film cartridge 3 from the stock conveyor 1. This magnet arm 21 has a pair of yokes 23 in the shape of a broken circuit, and an electromagnetic coil 25 is provided on the yokes 23 . Then, a horizontal magnetic field A is applied to the upper side 23b of the yoke 23.
This is so that it occurs. This magnetic arm 21
has a length that makes contact with the entire row of film cartridges 3b in the front row lined up on the stock conveyor 1, and is moved between the stock conveyor 1 and the discharge conveyor 19 by a drive device to be described later.
The film cartridge 3b in the front row
Absorb everything.

4 and 5 show the drive device for the holding device 9 and the magnetic arm 21 shown in FIG. 1. FIG.

That is, a fixed frame 11 is provided above each conveyor I, 19, and a holding device 9 is attached to this fixed frame 11.
A cylinder device 31 for driving the lifting rod 13 is attached. Further, a movable body 35 is slidably attached to a guide bar 33 installed on the fixed frame 11, and the magnet arm 21 is supported by a bracket 37 hanging from the movable body 35. The movable body 35 is connected to the connecting arm 4 by a cylinder device 39 provided on the fixed frame 11.
It is designed to be driven through 1.

During transfer, the magnet arm 21 is moved back and forth to attract the film cartridges 3b in the front row on the stock conveyor 1 by magnetic force, and transfer them onto the discharge conveyor 19 one line at a time. In this case, since the holding device 9 presses and holds the film cartridge 3a in the second row from the front, even if the film cartridge 3a in the second row is magnetically attracted via the film cartridge 3b in the first row, the film cartridge 3a in the front row Only things can be transported. After the transfer, the holding device 9 is released, the stock conveyor 1 is operated, and the second film cartridge 3a from the front row is pressed and held again.

In the above embodiments, the transfer of a film cartridge was described, but the present invention is not limited to this and can also be applied to transfer of a substantially cylindrical magnetic material having a non-magnetic protrusion at one end, such as a spray can. I can do it.

〔Effect of the invention〕

As explained above, according to the magnetic material transfer device according to the present invention, the electromagnetic transfer means sequentially attracts the magnetic materials arranged on the stock conveyor starting from the first row, and transfers them onto the discharge conveyor. As a result, the magnetic bodies do not come into contact with each other and damage the surface, and can be safely and efficiently transferred in a predetermined posture.
