Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement in a container used for transporting coils, particularly a container equipped with a structure to prevent the cores of the stored coils from falling out.

[Conventional technology and its problems]

As a container for transporting coils such as aluminum foil, there are two
There is a structure in which two receivers are installed facing each other, and the receivers receive the winding core of the coil to support the coil in a suspended state. In a container with the above structure, in order to prevent the coil from falling off during transportation, it is necessary to securely lock the winding core to the receiver. , a long hole in the vertical direction into which the core fits is provided in the receiver, and after the core is inserted into the long hole, a retaining pin is inserted into the opening on the top of the long hole, and the core is inserted above the core. I am trying to prevent it from slipping out.

However, with this method, it is necessary to insert and remove the pins each time an individual coil is loaded or unloaded, so there is a problem that the work is very time-consuming. There have been many accidents where coils have fallen off due to insufficient installation.

In order to deal with the above-mentioned problems, the present applicant has developed a container equipped with a structure to prevent the core from falling out, which can automatically prevent the core from falling out of the holder.
- Proposed by No. 2071. This container is
As shown in FIGS. 11 and 12, a vertically elongated hole 6 in the receiver 3 has an open top surface and into which the winding core B of the coil is fitted.
The coil has a structure in which a cam plate 20 is swingably attached to the side of the vertical hole 6 to slide into the winding core and prevent it from coming off. The protruding part of the cam plate 20 that protrudes inward is pushed outward and is fitted into the hole, and when the winding core is settled at the bottom of the vertical hole, the cam plate returns to its normal position and the protruding part of the cam plate 20 is inserted into the hole. It is designed to stop the upward movement of heart B and prevent it from slipping out. In addition, in order to take out the core from the longitudinal hole, the cam plate can be pulled out upward by rotating the cam plate by 180° in a direction in which the protruding portion faces outward.

However, in the above structure for preventing the core from falling out, if the container falls sideways during loading and unloading, the cam plate may rotate downward and no longer protrude from the vertically elongated hole. For this reason, there was a risk that the winding core would come out of the vertical hole and the coil would fall off.

This idea was made in view of the above problems, and by improving the above-mentioned retaining structure, it is possible to create a container that automatically retains the core and prevents the coil from falling out when it is tipped on its side. This is what we are trying to provide.

[Means for solving problems]

In order to achieve the above object, this invention forms a vertical hole in a pair of receivers attached to both sides of the upper surface of the pallet, the upper surface of which is open and into which the core of the coil is fitted with almost no gaps. A pair of semicircular cam plates, on which the winding core slides, are attached to both sides of the cam plate so that they can swing at the top of the center of gravity, with the arcuate surfaces at the bottom, and the arcuate surfaces of each cam plate are Time,
It protrudes toward the inside of the vertically elongated hole, and when the core slides into contact with the circular arc surface and is inserted into the vertically elongated hole, the cam plate pivots from the pivot point toward the center of the core. The radius of the circular arc surface is set smaller than the distance up to the outer periphery of the core, and when the core is pushed out from the vertical hole, the arc surface has a part above the center of the core that is connected to the outer periphery of the core. There is an abutting part that abuts, and the distance from the abutting part to the swinging fulcrum is equal to or greater than the distance from the swinging fulcrum to the center of the core to the outer periphery of the core. The configuration was set to .

[Effect]

In the container constructed as described above, when the core is inserted into the longitudinal hole, the core is fitted into the hole by pushing outward the arcuate surface of the cam plate that projects inside the longitudinal hole. At this time, since the amount of protrusion of the arc surface, that is, the radius of the arc, is smaller than the distance from the swing fulcrum to the outer periphery of the core, the cam plate returns to its normal suspended state.

From this state, when the core is pushed upward through the vertical hole, the arcuate surfaces of both cam plates protrude above the vertical hole, so the core tries to rise by pushing up the cam plate from below. In this case, the distance between the contact part of the protrusion and the swinging fulcrum of the cam plate is equal to or greater than the distance from the swinging fulcrum to the outer periphery of the winding core, so the winding core is located between the protrusions of both cam plates. Movement is stopped between the two, and upward escape is stopped.

If the container falls on its side, the center of gravity of the cam plate is below the swing fulcrum, so the arcuate surface of at least one of the cam plates attached to both sides of the vertical hole will face downwards, causing the vertical hole to collapse. The core protrudes inward, and the core is prevented from slipping out between its arcuate surface and the wall surface of the vertically elongated hole.

To pull out the core from the longitudinal hole, the cam plate is rotated in a direction in which the protruding portion retreats from the longitudinal hole.

〔Example〕

Hereinafter, embodiments will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, the container according to the embodiment of this invention includes a pallet 1, a pair of frame frames 2, 2 standing upright on both sides of the long side of the pallet 1, and the pallet 1. It consists of a pair of receivers 3, 3 that are mounted opposite to each other on the upper surface of the holder.

A plurality of inclined plates 5 are attached to the inside of the frame frame 2 at regular intervals in the length direction, and the support 3 includes slide plates 4 attached to both sides of the inclined plates 5.
are fitted into the gaps between the inclined plates 5 from above, so that they can be mounted upright on both sides of the upper surface of the pallet 1. The interval between the two receivers 3, 3 is appropriately selected depending on the dimensions of the container to be loaded.

As shown in FIGS. 2 and 3, the center of the upper surface of the receiver 3 has an open upper surface and a winding core B
A vertically elongated hole 6 is formed into which the cylindrical member is fitted with almost no gaps, and cam plates 7, 7 are attached to both sides of the elongated hole 6. This vertically elongated hole 6 is formed by fitting a steel guide plate 9 bent into a U-shape into a recess provided in the frame 3a of the holder 3. As shown in FIG. 2, a vertically long notch hole 11 through which the cam plate 7 is inserted is formed.

The cam plate 7 is made of a substantially half-moon-shaped plate material, and is connected to the end surface of the support plate 10 via a pin 8 so that its upper end can rotate from its center of gravity so that a portion of the cam plate 7 protrudes into the vertically elongated hole 6. , the support plate 10 is connected to the guide plate 9
By attaching it to the frame 3a along the side of the
It is inserted through the notch hole 11 of the guide plate 9 and freely swings inside the vertically elongated hole 6.

The lower surface of the cam plate 7 in a suspended state is formed into an arcuate surface 12 centered on the center of the pin 8, that is, the swing fulcrum 8', and when normally suspended, the surface of the arcuate surface 12 is A portion forms a protruding portion 13 that protrudes inward from the vertically elongated hole 6. Further, a locking portion 14 that protrudes in the horizontal direction is provided on the upper portion of the straight side of the cam plate 7, and a notch portion 14' corresponding to the increased weight of the locking portion 14 is provided. The left and right weights are balanced, and when the cam plate 7 is locked with the pin 8, it is suspended with the upper side horizontal and the arcuate surface 12 facing downward.

As shown in FIG. 5, the notch hole 11 has a lower opening larger than the arc radius of the circular arc surface 12 of the cam plate 7, with the horizontal line a passing through the swing fulcrum 8' as a boundary, and 8' to the end of the locking part 14, and the upper opening is formed to be larger than the length to the end of the locking part 14. If the container rolls over by 90 degrees, the opening shown in FIG. As shown in FIG. 2, one of the cam plates 7 can freely rotate in a direction in which the arcuate surface 12 faces outward from the vertical hole 6, so that the entire cam plate 7 is moved out of the vertical hole 6. However, the other cam plate 7 is
Since the locking portion 14 comes into contact with the guide plate 9 and its movement is stopped, the coil A can be prevented from coming off.

The radius d of the circular arc surface 12 is determined by the radius d of the winding core B from the swing fulcrum 8' toward the center C of the winding core B when the winding core B is fitted into the bottom of the vertically long hole 6 as shown in FIG. It is set to be smaller than the distance x to the outer periphery. Therefore, even if the cam plate 7 rotates around the pivot point 8' in the state shown in FIG.
3 and the winding core B do not interfere, and the cam plate 7 is
As shown in FIG. 6, it returns to the normal suspended state due to its own weight from the state of being pushed to the outside of the vertically elongated hole 6 (FIG. 7).

Further, when the core B is pushed up from the state shown in FIG.
5 is located above the center C of the winding core B, and a portion of the arcuate surface 12 above the contact portion 15 projects inside the vertical hole 6. When the winding core B is in contact with the cam plates 7, 7, the force applied from the winding core B to the cam plates 7, 7 acts in the radial direction of the arcuate surface, that is, toward the swing fulcrum 8'.
No rotational force acts on the cam plates 7, 7, and the cam plates 7,
7 is in a stopped state. Therefore, the rise of the winding core B is suppressed by the protrusions 13, 13 of both the cam plates 7, 7, and the winding core B is in a restrained state, and is prevented from coming off upward.

This embodiment has the above-mentioned structure, and the operation will be explained next. When the core B of the coil A is inserted into the vertical hole 6 from the state shown in FIG. 5, the core B will be as shown in FIG. 6. The protrusions 13, 13 of the cam plates 7, 7, which protrude inside the elongated hole 6, are pushed outward and fitted into the elongated hole 6. Then, as shown in FIG. 7, when the winding core B is inserted into the bottom of the vertically elongated hole 6, the cam plates 7, 7 return to the normal suspended state due to their own weight, and each protruding part 13, 13 is vertically elongated. It protrudes into the hole 6.

When the core B is pushed up from the state shown in FIG.
The coil is held between 3 and 13, and the coil is automatically prevented from coming off.

On the other hand, when the container falls on its side, the centers of gravity of the cam plates 7, 7 are located below the respective rocking supports 8', 8', so as shown in FIG.
Rotate so that 2 and 12 are on the lower side. That is, the lower cam plate 7 is located below the longitudinal hole 6 and does not protrude into the longitudinal hole 6, but the upper cam plate 7 is
The arcuate surface 12 is in a state of protruding into the vertically elongated hole 6. Therefore, the movement of the core B that is about to roll out is prevented by the protrusion 13 of the cam plate 7 protruding into the longitudinal hole 6.
and the longitudinal hole 6 to prevent the coil from coming off, thereby preventing the coil from falling off.

To remove the core B, move the cam plate 7 to the protrusion 13
is retreated to the outside of the vertically elongated hole 6 and rotated to the state shown by the one-dot chain line in FIG. In reality, it is troublesome to hold the cam plate 7 while working, so
As shown by the solid line in FIG. 10, the cam plate 7 is rotated approximately 180° until its locking portion 14 comes into contact with the core B, and in this state the core B is pushed up. in this case,
The core B is pushed out of the cam plates 7, 7, and the cam plates 7, 7 rotate to return to the normal state shown in FIG. 5.

[Effect of the invention]

By having the container of this invention configured as described above, it is possible to automatically prevent the core from falling out simply by fitting it into the vertical hole of the holder, and even if it falls on its side, the cam plate Since one side always protrudes into the longitudinal hole and prevents the core from coming off, it is possible to completely prevent the accident of the coil falling off.

In addition, since the winding core can be removed by simply rotating the cam plate, the operation is extremely simple and has the effect of greatly improving work efficiency when loading and unloading the coil.
