Description

The present disclosure relates to an article storage tray and its usage.

Ferrite sintered magnets have a maximum energy product of only 1/10 of rare earth-based sintered magnets (for example, NdFeB-based sintered magnets), but because the main raw material is inexpensive iron oxide, they are excellent in cost performance and chemical. It has the feature of being extremely stable. Therefore, it is used for various purposes such as various motors and speakers, and the world production weight is still the largest among magnet materials.

At the ferrite sintered magnet manufacturing factory, a large amount of magnets are produced and shipped every day. When shipping, relatively small items are often stored in trays and shipped. In this case, for example, in the case of an arcuate ferrite magnet having a relatively thin thickness, a plurality of (plurality) magnets (for example, in units of 5) are placed in each storage space of one tray in which a plurality of storage spaces are formed. And 10 units, etc.) are stacked and stored. That is, there are 20 storage spaces, and if each storage space is stacked and stored in units of 5, 100 magnets can be stored in one tray.

In order to stack and store a plurality of (plural) magnets (for example, in units of 5 or 10), first, a plurality of magnets are laminated and a laminated body (simply laminated and adhered, etc.) (Do not do), and the laminate is grasped by an industrial robot or a worker's hand and stored in the storage space of the tray.

However, each storage space of the tray is provided with a support member (holding member) for supporting (holding) the side surface (four places) of the magnet so that the magnet after storage does not move during transportation or the like. Therefore, when using an industrial robot, it is difficult for the gripper (grip mechanism) to enter the storage space, and when it is performed by the operator's hand, it is difficult for the fingers to enter. Therefore, when an industrial robot is used, it is necessary to make the gripper thin, but there is a problem that the gripping force is lowered. Further, when the operator performs the work, it is necessary to use a dedicated tweezers or the like, and there is a problem that the work efficiency is lowered.

Is. At this time, the recess 15 of each holding member has an opening facing the storage space side.

The quadrangular flat plate-shaped base portion 14 is made of, for example, PVC (polyvinyl chloride). It may be composed of other materials. The shape may be a square or a rectangle as long as it is a quadrangle, and the corners and sides may be C-chamfered or R-chamfered. The base portion 14 and each holding member may be integrally formed, or may be formed of separate members and fixed by a known method (for example, an adhesive or a screw). When it is integrally formed, for example, it may be machined from a single PVC plate.

The base portion 14 may be provided with a through hole for weight reduction in a portion that does not affect the storage of articles, for example, in the area of the storage space 16. The shape of the through hole does not matter (circular, oval, rectangular, etc.). The number of through holes provided in one storage space 16 is also arbitrary (s). Further, it may be provided in the area of a part of the storage space 16 or may be provided in the area of the entire storage space 16 (15 places in FIG. 1). By providing a through hole in the area of all the storage spaces 16, the weight reduction effect of the article storage tray 1 is increased. Further, a hole (recess) that does not penetrate may be used instead of the through hole.

There is. That is, if the first holding member 11 is arranged in the upper left of FIG. 1, the opening of the recess faces diagonally downward to the right 45 degrees, and if the first holding member 11 is arranged in the lower left of FIG. 1, the recess is recessed. The opening of the is arranged so as to face 45 degrees diagonally upward to the right. The angle does not have to be 45 degrees as long as it can hold a plurality of stacked articles (the angles may be slightly different). The height dimension of the first holding member 11 from the main surface and the width and depth of the surface parallel to the main surface are appropriately selected in consideration of the balance with other holding members according to the shape and dimensions of the article to be stored. .. In the embodiment of the present disclosure, the width and depth of the first holding member 11 are set to be about 1/2 of that of the third holding member 13.

As shown in FIG. 1, the second holding member 12 has a prismatic shape as a whole. The second holding member 12 is arranged in parallel with each side of the base portion 14 in the vicinity of the peripheral edge other than the four corners of one main surface of the base portion 14. In FIG. 1, 12 second holding members 12 are arranged, the second holding members 12 (8 pieces) arranged on the upper side and the lower side (upper and lower side) of FIG. 1, and the left side and the right side of FIG. The shape is different from the second holding members 12 (4 pieces) arranged on the (left and right sides). Regardless of the upper and lower sides and the left and right sides, the second holding member 12 has recesses 15 on the main surface for holding a plurality of stacked articles at two corners on the center side of one main surface of the base portion 14. On the other hand, it is continuously formed in the vertical direction. For example, in the case of the four second holding members 12 arranged on the upper side of FIG. 1, they are arranged on the left side of FIG. 1 so that the openings of the recesses face diagonally downward 45 degrees to the left and 45 degrees diagonally downward to the right. In the case of the second holding member 12, the openings of the recesses are arranged so as to face 45 degrees diagonally upward to the right and 45 degrees diagonally downward to the right. The angle does not have to be 45 degrees as long as it can hold a plurality of stacked articles (the angles may be slightly different). The height dimension of the second holding member 12 from the main surface and the width and depth of the surface parallel to the main surface are appropriately selected in consideration of the balance with other holding members according to the shape and dimensions of the article to be stored. .. In the embodiment of the present disclosure, the depth of the second holding member 12 arranged on the upper and lower sides is set to about 1/2 of the third holding member 13, and the depth of the second holding member 12 arranged on the left and right sides is set. The width is set to about 1/2 of the third holding member 13.

The third holding member 13 has a prismatic shape as a whole. The third holding member 13 is arranged in a region other than the peripheral edge of one main surface of the base portion 14 in parallel with each side of the base portion 14 and in a grid pattern. In FIG. 1, eight third holding members 13 are arranged. In the third holding member 13, recesses 15 for holding a plurality of stacked articles are continuously formed at all corners (4 locations) in a direction perpendicular to the main surface. That is, in FIG. 1, the openings of the recesses are arranged so as to face diagonally upward to the left 45 degrees, diagonally upward to the right 45 degrees, diagonally downward to the right 45 degrees, and diagonally downward to the left 45 degrees. The angle does not have to be 45 degrees as long as it can hold a plurality of stacked articles (the angles may be slightly different). The height dimension of the third holding member 13 from the main surface and the width and depth of the surface parallel to the main surface are appropriately selected in consideration of the balance with other holding members according to the shape and dimensions of the article to be stored. ..

Each holding member (first holding member 11, second holding member 12, third holding member 13) is composed of, for example, PVC (polyvinyl chloride). It may be composed of other materials. Further, it may be made of the same material as the base portion 14, or may be made of a different material.

A recess 15 for holding a plurality of laminated articles formed on each holding member will be described with reference to FIG. FIG. 2 is a partially enlarged explanatory view of the third holding member of the article storage tray according to the embodiment of the present disclosure. As shown in FIG. 2, the recess 15 is formed continuously in the direction perpendicular to the main surface, and has an Ω-shaped cross section. The article is held by contacting the opening 15a of the recess 15 with the periphery of the corner of the article to be stored. At this time, the tip of the corner of the article stays in the recess 15, and the opening 15a is opened so as not to come into contact with the inner wall of the recess. In the embodiment of the present disclosure, the opening angle of the opening 15a is about 90 degrees. As a result, damage to the tip of the corner of the stored article is reduced.

An example in which an arcuate ferrite magnet having a rectangular plan view is stored in the article storage tray of the embodiment of the present disclosure will be described with reference to FIGS. 1 and 3.

First, a plurality of magnets (long side side) are sandwiched between an industrial robot, a laminating jig, or a worker so that the convex surface (outer peripheral surface) of the arc of the arc-shaped ferrite magnet is on the bottom. Here, 5 pieces) are laminated to form a laminated body. This laminated body is merely a laminated magnet and is not bonded. Therefore, in order to maintain the laminated body, the side surface (long side of the magnet) of the laminated body is sandwiched by the hands of an industrial robot or an operator.

Next, the sandwiched laminate is stored in the storage space 16 of the article storage tray 1 shown in FIG. At this time, the sandwiched laminate is stored in the storage space from the upper direction of the article storage tray 1 (from the front to the back of the paper in FIG. 1), but in the direction in which the laminate is sandwiched, that is, on the side surface of the magnet. Since there is no holding member or the like on the base portion 14 of the article storage tray 1 in the vertical direction (horizontal direction in FIG. 1) (because there is nothing on the base portion 14), the gripper of the industrial robot or the operator It is easy to access, and the sandwiched laminate can be easily stored in the storage space 16, improving work efficiency.

When the laminated body is completely stored in one storage space, the laminated body is stored in the next storage space (for example, the storage space on the right side of the storage space 16 in FIG. 1) in the same manner as described above. In this case as well, since there is no holding member or the like in the direction in which the laminated body of the storage space is sandwiched (left-right direction in FIG. 1), the gripper of the industrial robot or the operator can easily enter the laminated body. Can be easily stored in the storage space. This is repeated in sequence to store the laminate in all the storage spaces. As a result, a total of 75 arc-shaped ferrite magnets, 5 each in 15 storage spaces, can be easily and highly efficiently stored. FIG. 3 shows an example of an article storage tray in which all arc-shaped ferrite magnets are stored.

In the above example, the number of laminated arc-shaped ferrite magnets is 5, and the storage space is 15 (5 x 3 rows). However, the thickness, size, and holding of the magnets are maintained. The number can be arbitrarily set in consideration of the height dimension of the members, the strength of the entire tray, the weight to be transported, and the like. Further, in the above example, the arcuate ferrite magnet is stored so that the convex surface (outer peripheral surface) of the arc is on the bottom, but it may be stored so that the convex surface (outer peripheral surface) of the arc is on the top.

Next, the arcuate ferrite magnet stored in the article storage tray of the embodiment of the present disclosure is used as a jig for transferring to another article storage tray (hereinafter, may be referred to as a "replacement jig"). An example will be described below.

First, as shown in FIG. 3, all the arcuate ferrite magnets are stored in the article storage tray (hereinafter referred to as “the main tray”) of the embodiment of the present disclosure. Next, prepare another article storage tray (hereinafter referred to as "other tray"), and place the other tray on the main tray that stores all the arc-shaped ferrite magnets so that the storage space faces downward (upside down). Place it. Then, the tray is turned upside down with the other tray placed on the main tray. As a result, all the arcuate ferrite magnets stored in this tray are transferred to another tray. Finally, remove the book tray on the other tray.

For example, in the case where the arcuate ferrite magnet is stored in the tray (other tray) supplied by the customer, the other tray supplied by the customer is the magnet side surface (4 locations) as described in the background technology. A support member (holding member) is provided to support (hold) the magnet, and when using an industrial robot, it is difficult for the gripper (grip mechanism) to enter the storage space, and when it is performed by the operator's hand, it is difficult for the finger to enter. In addition, this tray is used as a replacement jig. As a result, the arcuate ferrite magnet can be easily and highly efficiently stored in another tray supplied by the customer.

The other tray is formed so that the holding member of the article faces a position other than the arrangement position of the holding member of the main tray, that is, facing the magnet side surface (long side side and short side side) of the arcuate ferrite magnet. Can be used. It is desirable that the article storage space of the other tray is formed to have substantially the same size, the same position, and the same number as the storage space of the main tray. That is, the holding members of the main tray and the holding members of the other trays are set so as to fit perfectly without colliding with each other. If the customer requests that the convex surface (outer peripheral surface) of the arc of the arc-shaped ferrite magnet be on the top, the tray should be stored so that the convex surface (outer peripheral surface) of the arc is on the other tray. You can transfer it to.

A plurality of protrusions (knobs) may be provided on the back surface (the surface on which the holding member is not formed) of the tray. This tray is particularly effective when used as a replacement jig. For example, if the book tray is placed directly on the workbench, there is no gap between the back surface of the book tray and the workbench when the tray is turned upside down with another tray placed on the workbench. It may be difficult to grip the tray and other trays with the grippers of an industrial robot or the hands of an operator. By providing the protrusion, a gap is formed between the back surface of the main tray and the workbench, so that the main tray and the other tray can be easily gripped. Further, when the main tray on the other tray is finally removed after being turned upside down, there is an advantage that workability is improved by grasping and removing the protrusion. From such a viewpoint, it is preferable to provide a plurality of protrusions, and it is preferable to provide at least three, more preferably four or more protrusions. The position of the protrusion is not particularly limited, but it is preferably provided near the four corners of the back surface of the main tray or near the center of each side of the peripheral edge of the back surface of the main tray. Further, it is preferable that the protrusion is configured to be removable from the main tray.

Further, a reinforcing plate such as an aluminum plate may be provided on the back surface of the tray. By providing the reinforcing plate, it is possible to improve the strength of the tray and prevent deformation. When the reinforcing plate is provided, the protrusion may be provided on the reinforcing plate. Further, the reinforcing plate may be provided with a through hole for weight reduction. This tray is particularly effective when used as a replacement jig.

After storing all the arc-shaped ferrite magnets in the article storage tray of the embodiment of the present disclosure, or by using the article storage tray of the embodiment of the present disclosure as a replacement jig, all circles in other article storage trays. After transferring the arc-shaped ferrite magnets, it is preferable to check the number of arc-shaped ferrite magnets stored in each storage space. As a method of confirming the number of members, for example, the height of the entire plurality of (plurality) magnets stored in each storage space is measured by a laser measuring instrument, and the number of members is confirmed from the measurement result. Of course, the number of members may be confirmed by other methods such as visual inspection.

According to the embodiment of the present disclosure, it is possible to provide an article storage tray capable of easily storing a plurality of articles, particularly an arcuate ferrite sintered magnet, with high work efficiency, and to implement the present disclosure. By using the article storage tray according to the form as a replacement jig, it is possible to easily and highly efficiently store a plurality of articles, particularly a plurality of arcuate ferrite magnets, in another article storage tray. Has industrial availability.
