Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a covering device that prevents fired products stacked on a base brick from falling and collapsing when the fired products are moved.

In ceramic factories, various types of fired products are piled up on platform-shaped bricks called platform bricks, which are formed by assembling individual brick pieces into a certain rectangular parallelepiped shape, and are transported, processed, and treated as one unit. Perform work such as storage.

By the way, in the past, pedestal bricks were made by simply placing individual brick pieces together and no active measures were taken to maintain their shape.
There were problems such as the shape of the container would often collapse and the fired products stacked on top would fall and break. This was especially common during movement using a lift or crane, or during transportation on a roller conveyor.

To solve this problem, a frame was devised to firmly fix the base bricks in that shape, and the patent application No. 54-73175
It has been proposed as a number.

However, even if this frame is used, it is the base brick that is fixed, and the various fired products piled up on this base brick are stacked quite high from the frame, and Since no particular measures were taken to secure the fired products, it was not possible to prevent the fired products from falling.

Therefore, in this invention, when this frame is used,
The present invention addresses the above-mentioned drawbacks by providing a coating device that is attached to a frame and covers the entire fired product.

Embodiments of the present invention will be described below with reference to the drawings. Of the accompanying drawings, Fig. 1 is a perspective view of a base brick fixed with a frame, and Fig. 2 shows an outline of a coating device according to the present invention. 3 is a front view showing how the coating device is used, FIGS. 4 and 5 are side views, FIGS. 6 and 7 are partially enlarged sectional views of important parts, and FIG. 8 is a front view showing the coating device in use. FIG. 2 is a partial perspective view showing another embodiment of the coating device.

First, to give an overview of frame A, frame A is
Two long sides 1, 1 and two short sides 2, 2 are connected at the four corners via hinges 3... in a rectangular shape, and one of the long sides 1 is connected to two in the center. It is divided into two parts, and a fastening part 4 is formed at this part. As a specific structure of this fastening portion 4, outwardly bent flanges 5, 5 are formed at each end of the divided long side 1, and the flanges 5,
It is conceivable that through-holes 6, 6 are bored in 5, a threaded rod 7 is passed through the through-holes 6, 6, and the threaded rod 7 is tightened with nuts 8, 8 from both ends. By the way, such a frame A is made by expanding the fastening part 4 with the hinge 3 as a bending point on a base brick 10 formed by assembling brick pieces 9 and shaping it into a rectangular parallelepiped, and fixing it by wrapping it around it. I'm going. That is, long side 1, 1, short side 2,
Both of them have band-shaped protrusions 1a, 1a, 2 on the inside.
In addition to protruding a and 2a, the upper part is the contact part 1
b, 1b, 2b, 2b (usually a cushioning material 11 such as rubber is attached to the surface of the contact portions 1b, 1b, 2b, 2b),
The upper surface of the band-like projections 1a, 1a, 2a, 2a scoops up the bottom periphery of the rectangular parallelepiped base brick 10,
In addition, the cushioning material 11 presses and supports the outer circumferential surface. In addition, in the above, the band-shaped projections 2a formed on the short sides 2, 2,
2a may be formed with an upward slope from the center to both ends, so the base brick 10 also slopes in this direction, and accordingly, in order to further improve the stability of the fired product 12 placed on it. It is also possible to create a pyramid shape by following this slope.

Furthermore, several (usually three) holes 13 are drilled on the lower side of the strip-like protrusions 2a, 2a on the short sides 2, 2, and support rods 14 are passed between the holes 13. Hang it and tighten it with nuts 15 from the outside. Therefore, although the bottom surface of the base brick 10 is located above the top surface of the band-like protrusions 2a, 2a, the center portion thereof sag under its own weight, so that the base brick 10 is located above the band-like protrusion portions 1a. ,1a,2
In addition to a and 2a, it is also partially supported by these support rods 14...

By the way, the reason why the base brick 10 is firmly fixed by the frame A in this way is convenient for placing various fired products 12 on top of it and treating it as one unit for transportation to various locations and various processing. Furthermore, this frame A is adapted to be suitable for conveyance on a roller conveyor.

As a specific configuration for this purpose, first, both long sides 1, 1 and short sides 2, 2 have a considerable protrusion at their lower end portions, that is, the short sides 2, 2 have a thickness of hinge 3... and a protrusion larger than the protruding length of the support rod 14... which is hung between the long sides 1, 1, and the thickness of the hinge 3... and the outer side of the fastening part 4. Projection length (flange 5,
The outer protrusions 16, 16, 17, and 17 having a protrusion larger than half of the protrusion length of 5 are provided. As a result, regardless of the direction of conveyance, each other's outward protrusions 16, 16, 17,
The outer end surfaces of 17 are in parallel contact with each other, making it suitable for conveyance. In addition, the support rod 14... is the short side 2,
Since the nut 15 is fitted into the part protruding from 2, the outer protrusion 1 on this side
6 and 16, it would be a problem if the nut 15... could not be fully fitted, so this outer protrusion 1
6 and 16 are made to protrude considerably below the holes 13, taking into account the fitting allowance for the nuts 15.

Next, these four outward protrusions 16, 16, 1
The lower end surfaces of 7 and 17 are configured to be smooth and flush. Therefore, usually, of this part,
A means for inserting the fork of the lift is provided on the long sides 1 and 1, but in this invention,
This is the insertion hole 18..., and no measures such as cutouts or the like are taken to prevent the lower surface from being flush. Note that for lifting by a crane, it is not necessary to make any modifications to the lower surfaces of the outer protrusions 17, 17, so it is sufficient to provide ordinary hooks 19, etc.

In addition, there is a dividing point on one of the long sides 1, 1,
Therefore, the outer protrusion 17 is also not continuous in this part, but a wire 21 that is flush with the lower surface of the outer protrusion 7 on the other part of the long side 1 is provided in this hollow part 20. It is designed to be detachably attached using bolts 22, 22, etc.

By the way, the coating device B according to the present invention is detachably attached to the frame A as described above.

That is, the covering device B consists of a net frame 23 that completely covers approximately half of the fired products 12 stacked on the base brick 10, and columnar support shafts 24, 24 that support the net frame 23.

The net frame 23 is a metal frame 25 with strings 26 stretched in a net shape, and serves as a direct covering member for the fired product 12. Note that this net frame 23 has a main body part 27 that covers the sides of the fired product 12 and a ceiling part 28 that covers the ceiling part.
Of these, the main body portion 27 further includes a long side portion 29 located on the long side portion of the fired product 12, and short side portions 30, 30 located on the short side portions,
The two are connected by hinge structures 31, 31, and the ceiling part 28 is fixed to the upper surface of the main body part 27 with a suitable fastener.

In addition, in the main body part 27, a fixing structure 32 . As a specific example of this fixing structure 32..., a flange 34 with a through hole 33... is provided in a butt type, and the bolt 3
A conceivable option is to tighten the nut 36 through the nut 36.

On the other hand, the support shafts 24, 24 are provided vertically with their upper ends linked to the frame body 25 at the upper end of the long side 29 of the net frame 23, and the long side 1 of the frame A is connected to the lower end of the support shaft 24, 24.
Fitting structures 38, 38 are provided which are fitted into and fixed to fitting sleeves 37, 37 installed on the outside of the housing. As the fitting structures 38, 38, the support shafts 24, 2
It is conceivable that several through holes 39 are provided in the lower end of the sleeve 4, and the fixing pins 40, 40 are inserted into the holes along with the fitting sleeves 37, 37 for fixation.

Furthermore, since the fitting sleeve 37 and the frame 25 of the net frame 23 are not on the same vertical line, it is necessary to insert a bending structure 41 in the middle of the support shaft 24 to absorb this. Note that the bending structure 41 may be one in which the support shaft 24 is divided into two parts and these parts are pivotally connected with a pin 42. This bending structure 41, the plurality of through holes 39 described above, and the fitting structure 38 using the pins 40 make it possible to cope with the case where the fired products 12 have different heights and the pyramid-shaped stacking described above. Correspondingly, the frame body 25 of the net frame 23, the hinge structure 31..., the support shaft 24,
The interlocking structures 43, 43 at the upper end of the frame 24 are also made, for example, by making the holes in the frame 25 through which they are inserted into elongated holes or the like in that direction so that the angle can be changed.

The coating device B having the above configuration covers the fired products 12 stacked on the base bricks 10 fixed by the frame A. First, the supporting shafts 24 are connected to the fitting structure 38, 38, the short sides 30, 30 of the net frame 23 are folded back, and the long sides 29 cover approximately half of the periphery of the fired product 12. Next, if another coating device B is operated in the same way, this time the short sides 30, 30, 3 of each other are
Both are fixed by fixing structures 32 provided at 0 and 30. And finally both ceiling parts 2
8 and 28 are lowered onto the respective main body parts 27 and 27, and once both are fixed, the fixing structures 32 and 32 also provided thereon are operated to fix both. As a result, the fired product 12 is completely covered by the net frame 23. In addition, in the above operation, the main body part 27 and the ceiling part 28 are
It may be integrated in advance, and in this case, the net frame 23 is usually suspended from above so that its support shafts 24, 24 are inserted into the insertion sleeves 37, 37. Lifting means 44, 44 are provided on the ceiling portion 28.

In addition, the band-like protrusions 2a, 2a on the short sides 2, 2 of the frame A are set to have an upward slope as they go from the center to both sides, so the base brick 10 also becomes mid-low in this direction, and the fired product 12 also becomes low. As mentioned above, in this direction, the cross sections may be stacked up on a staircase, but in order to deal with this, it is also possible to form the ceiling part 28 in the shape of a staircase along the long side part 29.

Since the present invention is as described above, the following effects can be expected.

First, the fired products 12 piled up on the base brick 10
On the other hand, since it can be covered with the covering device B consisting of the net frame 23 as described above, the fired product 12 will not fall even if handled a little roughly.
It never collapses.

The main body of this coating device B is the net frame 2.
3, the fired product inside 12
It is preferable because the condition can be clearly seen, and it also has the advantage of being small in diameter.

Furthermore, since this coating device B is removable from the frame A, it is only necessary to attach it only when necessary (for example, when transporting by lift or crane).
You can remove it later. In addition, this attachment/detachment operation is also performed on the support shafts 24, 24 as described above.
The fitting structure 38, 38 of the net frame 23 and the fixing structure 32 of the net frame 23 can be operated very quickly and easily.
