Abstract

PURPOSE:To protect the painted face of magnetic material from damaging, in a carrying device for a film patrone having non-magnetic material at one end, by constructing such that a work mounting tray stacked in a container is pushed up stage by stage to carry the work while adsorbing through magnetic material. CONSTITUTION:Upon carrying-in of a container 1 onto a push-up device 13 arranged below the final position of a roller conveyor 17, a cylinder 21 is driven to push up the bottom face of a final stage tray 5 in the container 1 through an arm 25, an elevating member 27, and a push-up rod 29. Consequently, the tray 5 will lift sequentially over the tray 5 while employing the sum of the height of film patrone 3 and the thickness of the bottom face of tray 5 as single pitch, thus to push out the film patrone 3 in the uppermost tray 5. Then it is adsorption held by magnetic attraction transfer unit 15 and moved to the side. With such arrangement, it can be transferred efficiently without damaging the painted outerface 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 (
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 film cartridge transfer device, 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 Laid-Open No. 57-64729). Other conventional transfer devices include vibration transfer using a vibrating feeder or chucking transfer using a robot.

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 accommodates a plurality of magnetic materials in a container via trays in an aligned state and in a multi-tier stacked state, pushes up the trays one after another from below, and pushes up the trays sequentially from below. The magnetic material on the upper tray is transferred to another location using a magnetic attraction type transfer device while remaining aligned.

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 schematically shows the film cartridge transfer process according to this embodiment.

The film cartridges are stored in a plurality of stacked layers in the container 1a, and are transported to a predetermined position by an unloading conveyor such as a roller conveyor. A tray is used as a stacked storage means in the container 1. That is, each film cartridge is placed on one tray in a plurality of rows, and the trays on which the film cartridges are placed are stacked in the multi-stage container 1.

When the container 1 is transported to a predetermined position (a), the film cartridges 3 are taken out one by one starting from the uppermost one, as shown in (b), by a magnetic attraction transfer device to be described later. The trays 5 are removed as shown in (c), stacked on top of each other, and transported to the collection line.

The film cartridges 3 transferred from the container 1 are transferred from the front row to
They are separated and transported one by one, and sent to the next process in an upright position (e).

On the other hand, empty container 1 from which film cartridge 3 has been taken out
As shown in (G), the tray 5 is collected inside and sent to the pool line (H), and then returned to the first film cartridge loading position.

To explain the shape of the film cartridge here, as shown in FIG.
b stands out. In addition, the film cartridge main body 3a
Pattern 4 displays film sensitivity etc. on a part of the outer periphery of the
As described above, this pattern 4 is resistant to damage due to contact or the like.

Figures 3 and 4 show container 1 of film cartridge 3.
The stacked storage structure inside and the planar shape of the tray 5 are shown.

The container 1 has a rectangular parallelepiped shape with an open upper surface, and a plurality of holes 7 for inserting push-up ronds, which will be described later, are provided in the bottom wall.

The tray 5 can hold a plurality of film cartridges 3 arranged vertically and horizontally with the projections 3b facing upward. Film patrone 3
The main body portion 3a has a cylindrical shape, and is preferably arranged in a staggered manner in order to increase the arrangement density.

In this way, the trays 5 on which the film cartridges 3 are placed are housed in the container 1 in multiple stages and stacked. FIG. 5 shows a take-out device 11 for taking out the film cartridges 3 from the container 1.
The configuration is shown below. Further, FIGS. 6 to 8 show the structure of the magnetic attraction type transfer device 15 of the take-out device 11 in detail.

The take-out device 11 includes a push-out device 13 that pushes up the tray 5 in the container 1 from below to project the uppermost film cartridge 3 above the container 1, and a magnetic force that collectively applies a magnetic force to the three protruding uppermost film cartridges. It is composed of a magnetic attraction type transfer device 15 that attracts the transfer device and transfers the transfer device to another device.

The push-up device 13 is arranged below the final conveyance position of the roller conveyor 17 that conveys the container l. This pushing up device 13 is a drive cylinder 21 attached to a fixed frame 19.
And arm 2 is attached to the cylinder rod 23 of this cylinder 21.
5, and a plurality of push-up rods 29 projecting upward from the elevating body 27. For example, four push-up rods 29 are provided, and contact the bottom surface of the lowermost tray 5 through the roller gap of the roller conveyor 17 and the hole 7 in the bottom wall of the container 1, and push up the film cartridge 3.
The total distance of the height of the tray and the thickness of the bottom surface of the tray 5 is taken as one pitch, and the trays 5 are successively pushed up by the number of 50 trays.

Further, the magnetic attraction type transfer device 15 has a fixed frame 31
A guide rail 33 that is supported by a guide rail 33 that extends in a direction (horizontal direction) perpendicular to the paper plane of FIG. It has an arm 37 that protrudes in a direction perpendicular to the guide rail 33 and moves laterally along the guide rail 33, and a magnetic transfer means 39 that is attached to the arm 37 so as to be movable up and down. As shown in FIG. 6, the magnetic conveyance means 39 includes a box-shaped main body 41, a cylinder (hereinafter referred to as a main body lifting cylinder) 43 that allows the main body 41 to be supported by the arm 37 so as to be movable up and down, and a cylinder that can be moved up and down into the main body 41. It has a horizontal magnet body 45 housed therein that generates a downward magnetic field A, and a cylinder 47 (hereinafter referred to as a magnet lifting cylinder) that moves the magnet body 45 up and down within the main body 41 by a predetermined stroke.

As shown in FIG. 9, the magnet body 45 is made into a flat plate by integrally fixing a large number of small square plate-shaped permanent magnet elements 45a with different polarities adjacent to each other vertically and horizontally in a matrix shape. It was formed in By gathering the small magnetic fields a generated in each permanent magnet element 45a, a strong uniform magnetic field A having a small height and a wide width is formed below the magnet body 45 as a whole.

Further, as shown in FIG. 6, the magnet cylinder 47 has a structure in which cylinder units 47a of small pitches are combined to have a large pitch as a whole. That is, the cylinder rods 47a have the same structure, but the cylinder rods 47b connect the upward (both sides) and the downward (center) cylinder rods. The cylinder rod 47b of the upward cylinder unit 47a is connected to the top plate portion of the main body 41, and the magnet body 45 is suspended by the cylinder rod 47b of the downward cylinder unit 47a. This allows the magnet body 45 to move up and down within the main body 41 with a stroke twice as long as that of the cylinder unit 47a. Therefore, since there is no need to provide a cylinder with a long stroke, sufficient vertical movement of the magnet body 45 can be ensured even if the main body 41 is small and compact.

Note that a bottom wall 49 of the main body 41 is arranged below the magnet body 45. From the viewpoint of improving the emissivity of the film cartridge 3, it is desirable that the bottom wall 49 be made of a non-magnetic material so as not to generate residual magnetism.

Further, a holding frame 51 is suspended from the outer peripheral side of the bottom wall 49 of the main body 41.

The above transfer device 15 transfers a group of film cartridges 3 protruding above the container 1 to the stock conveyor 53.
To transfer to , perform the following operations.

First, as shown in FIG. 6, the bottom wall 49 of the main body 41 is aligned with the upper surface of the container 1, and the main body 41 is lowered by the main body lifting cylinder 43. When the main body 41 is lowered, the magnet body 45 is also lowered by the cylinder 47 for raising and lowering the magnet.

As a result, when the main body 41 descends to a predetermined height, the film cartridge 3 is attracted by the magnet 45 and held in contact with the bottom wall 49 of the main body 41.

Therefore, as shown in FIG. 7, the main body 41 is raised, and then the arm 37 is moved laterally along the guide rail 33 to convey it onto the stock conveyor 53, and as shown in FIG. lower it. Film patrone 3
When the lower end of the film cartridge 3 is placed on the stock conveyor 53, the cylinder 47 is operated to raise the magnet 45 and separate the film cartridge 3 from the bottom wall 49.

Thereafter, the above operation is repeated. In addition, the empty tray 5
During the above operation, the film cartridge 3 is removed and the next stage film cartridge 3 is pushed up by the pushing up device 13.

〔Effect of the invention〕

As explained above, according to the magnetic material transfer device according to the present invention, a large number of magnetic materials housed in a container are sequentially projected upward from the container by the push-up device, and are kept aligned by the magnetic attraction type transfer device. Since it is possible to transport a large amount of magnetic material to a predetermined location by using the magnetic material, a large amount of magnetic material can be transported safely and efficiently without damaging the surface due to mutual contact.
