Description

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

[Conventional technology and its problems]

Generally, when transporting coils such as aluminum foil using containers, two receivers are installed facing each other on the top surface of the pallet that forms the bottom of the container.
The receiver receives the core of the coil and supports the coil in a suspended state. In this case, in order to prevent the coil from falling off during transportation, it is necessary to securely lock the winding core to the receiver.
Conventionally, as a means for locking the winding core, a vertical elongated hole into which the winding core is fitted is provided in the receiver, and after the winding core is fitted into the elongated hole, the upper opening of the elongated hole is opened. A retaining pin is inserted into the core to prevent it from slipping out upwards.

However, with this conventional 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 extremely time-consuming. There have been many accidents in which coils have fallen off due to insufficient pin installation.

This idea was made in view of the above problems, and has a structure that prevents the core from falling out, which allows the core to be automatically retained in the receiver and can be removed with a simple operation. The purpose is to provide a container with

[Means for solving problems]

In order to achieve the above object, this invention forms a vertically long hole in the receiver with an open top surface into which the winding core is fitted with almost no gaps, and the winding core slides into the side of the vertical hole. A cam plate is swingably mounted in the vertically elongated hole, and a protrusion that normally protrudes toward the inside of the vertically elongated hole is formed on the cam surface on which the winding core of the cam plate slides. The radius is the distance from the pivot point of the cam plate toward the center of the core to the outer periphery of the core when the cam plate is inserted into the longitudinal hole. At least the portion of the protruding portion above the line connecting the swing fulcrum and the center of the winding core is set to be located within the range of the circle. , there is a contact part that contacts the outer periphery of the core above the center of the core, and the distance from the contact part to the swinging fulcrum is the same as the distance from the center of swing to the center of the core. The configuration was such that the distance was greater than the distance to the outer periphery.

[Effect]

In the container configured as described above, when the core is inserted into the vertical hole, the core pushes the protruding part of the cam plate that protrudes inside the vertical hole outward and is fitted into the hole. Because the distance from the upper part of the cam plate to the center of oscillation of the cam plate is smaller than the distance from the center of oscillation to the outer periphery of the core, the protrusion and the center of the cam plate are There is no interference between the cores, and the cam plate returns to its normal position, or returns to a position where the portion below the line connecting the center of swing of the protrusion and the center of the core comes into contact with the outer periphery of the core. .

From this state, when the core is pushed up so that it comes out of the vertical hole, the core tries to rise by pushing up the protrusion that protrudes into the vertical hole from below, but at this point, the contact part of the protrusion and the cam Since the distance to the center of swing of the plate is greater than the distance from the center of swing to the outer periphery of the core, the core is stopped in motion between the protrusion and the wall of the vertical hole, and cannot move upward. Escape can be stopped.

To remove the core from the vertical hole, rotate the cam plate in the direction in which the protruding part faces the outside of the vertical hole.
This is done with the protruding part protruding inside the hole.

〔Example〕 Hereinafter, embodiments will be described based on the attached 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 receiver 3 has slides attached on both sides thereof with the same inclination as the inclined plates 5. The plate 4 is connected to the inclined plate 5.
It can be installed upright on both sides of the upper surface of the pallet 1 by fitting it into the appropriate gap from above.

As shown in FIGS. 2 and 3, the upper center of the receiver 3 has an open top surface and a winding core B of the coil A.
A vertically elongated hole 6 is formed into which the cam plate 7 is fitted with almost no gaps, and a cam plate 7 is attached to the side of the elongated hole 6. The vertical 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. On one side of the guide plate 9, a fourth As shown in the figure, a vertically long notch hole 11 is formed into which the cam plate 7 can be inserted. Cam plate 7
The upper end is rotatably connected to the end surface of the support plate 10 by a pin 8, and 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 is attached to the inside of the vertically elongated hole 6 so as to freely swing. The upper and lower dimensions of the notch hole 11 are as follows:
The cam plate 7 can be rotated once around the pin 8.

Surface 12 of the cam plate 7 facing the vertical hole 6
As shown in FIG. When inserted into hole 6, core B
becomes the cam surface that comes into sliding contact. In the normal hanging state as described above, this cam surface 12 has an upper part that becomes a protruding part 13 that protrudes inside the longitudinal hole 6, and a lower part that retreats to the outside of the longitudinal hole 6 and becomes a retracted part 14.
It's getting old.

When the winding core B is inserted into the vertically elongated hole 6 from the state shown in FIG. Fitted inside. As shown in FIG. 7, when the winding core B is fitted into the bottom of the vertical hole 6, the protrusion 13 of the cam surface 12 moves from the swing fulcrum 8' to the swing fulcrum 8' in the protrusion 13, and the winding The distance l to the farthest part above the line connecting the center C of the core B is less than the distance x from the swing fulcrum 8' to the center C of the core B to the outer periphery of the core B. It is set to be small.

As a result, even if the cam plate 7 rotates around the swing fulcrum 8' in the state shown in FIG.
The cam plate 7 no longer interferes, and the cam plate 7 returns to its normal suspended state from the state shown in FIG. 6 due to its own weight (FIG. 7). In this case, if the center of gravity of the cam plate 7 is located inward of the longitudinal hole 6 in the normal state than in this embodiment, the cam plate 7 will further rotate from the state shown in FIG. The portion below the line connecting the swing fulcrum 8' of No. 13 and the center C of the core B comes into contact with the outer periphery of the core B and stops.

Next, when the core B is pushed up from the state shown in FIG. 7, the core B tries to rise by pushing up the protrusion 13 that projects into the vertical hole 6 above. In this embodiment, as shown in FIG. 8, the cam plate 7 rotates clockwise and a part of the protruding part 13 and the retreating part 14 of the cam surface 12 simultaneously contact the outer periphery of the winding core B. It shows. In this state, the contact portion 15 of the protrusion 13 is located above the center C of the winding core B, and is directed from the pivot point 8' toward the center C of the winding core B, with the swing fulcrum 8' as the center. It is set to be located outside the range of a circle whose radius is the distance y to the outer periphery of the winding core B. That is, the distance m from the contact portion 15 to the swing fulcrum 8' is set to be greater than the distance y.

Therefore, the rise of the winding core B is stopped by the protrusion 13 on the upper surface side of the outer periphery, and the winding core B is restrained between the protrusion 13 and the wall surface of the vertical hole 6, and moves upward. I can't get out.

Therefore, simply by fitting the winding core B into the longitudinal hole 6, the winding core B is automatically oriented and fixed in the longitudinal hole 6 by the natural movement of the cam plate 7, and is securely locked in the longitudinal hole 6.

Note that as a condition for restraining the winding core B, it is not necessary that the retreating portion 14 abuts on the outer periphery of the winding core B as shown in FIG. >l) should be satisfied.

To remove the winding core B, hold the cam plate 7 by hand and rotate it so that the protrusion 13 retreats to the outside of the longitudinal hole 6, so that the state shown by the broken line in FIG. 9, that is, the winding core B is inserted. Just leave it in the same state as when you did it. In reality, it is troublesome to hold the cam plate 7 by hand during work, so rotate the cam plate 7 until the rear end comes into contact with the winding core B, as shown by the solid line in Figure 9. In this state, the core B is pushed up and the cam plate 7 is simultaneously rotated and pulled out upward. In that case, the cam plate 7 rotates and returns to the normal state shown in FIG. 5 again.

[Effect of idea]

By having the container of this invention configured as described above, it is possible to automatically prevent the coil from falling out simply by fitting the core into the vertical hole of the receiver, completely preventing the accident of the coil falling off. It is possible, and
Since the winding core can be removed by simply rotating the cam plate, the operation is extremely simple and the work efficiency when loading and unloading the coil can be improved.
