Description

[Detailed description of the invention] This invention relates to a frame for fixing a base brick, which is used as a bottom member on which a fired object such as a brick, pottery, tile, or roof tile is placed, and is fixed in a certain shape. Among these, the present invention particularly relates to a frame for fixing base bricks suitable for conveying on a roller conveyor.

In view of the fact that there was no suitable means for fixing the base bricks in the past, the applicant devised a frame for fixing the base bricks that could be firmly fixed and easily moved. 54-7
It is proposed as No. 3175.

This proposal is based on the assumption that the movement will be carried out mainly by lifts and cranes, and the means for that purpose are also provided, but roller conveyors are also an important means of transportation in ceramic factories, so this time , which has been improved to be suitable for conveying on a roller conveyor.

Embodiments of this invention will be described below with reference to the drawings. Of the accompanying drawings, Fig. 1 is a perspective view of a frame for fixing a base brick according to this invention, and Fig. 2 shows a state in which this frame is attached to a base brick. The plan view, FIG. 3, and FIG. 4 are partially sectional side views showing the state in which the platform bricks are being conveyed on the roller conveyor using this frame.

Frame A has two long sides 1, 1 and two short sides 2, 2 connected to form a rectangle via hinges 3 at the four corners. One of the parts is divided into two at the center, and a fastening part 4 is formed at this divided part.

As a specific structure of this fastening portion 4, flanges 5, 5 bent outward are provided at respective ends of the divided long sides 1.
and drill through holes 6, 6 in the flanges 5, 5,
It is conceivable that the threaded rod 7 be passed through the through holes 6, 6 and tightened with nuts 8, 8 from both ends.

By the way, such a frame A has a base brick 10 formed into a rectangular parallelepiped by assembling brick pieces 9, and hinges 3...
The fastening part 4 is expanded using the bending point, and then the fastening part 4 is wrapped around the bending point and fixed.

That is, both the long side 1 and the L short sides 2, 2 have strip-like protrusions 1a, 1aj2a, 2a protruding inside thereof, and
Above this, contact parts 1 b, 1 b, 2 b, 2 b
(contact parts 1 b, 1 b, 2
Usually, a cushioning material 11 such as rubber is placed on the surface of b, 2 b.
...), the bottom periphery of the rectangular parallelepiped base brick 10 is attached to the band-shaped protrusions 1a, 1a, 2a, 2a.
The top surface of the cushioning material 1 scoops up the

In addition, in the above description, since the band-like projections 2a, 2a formed on the short sides 2, 2 are shaped with an upward slope from the center to both ends, the base brick 10 also slopes in this direction, The baked goods 12 placed along with this also follow this slope, forming a pyramid shape (see Figure 4).

Furthermore, on the lower side of the band-like projections 2a, 2a of the short sides 2, 2,
Open several (usually 3) 7L13...
A support rod 14 is placed between the holes 13 and tightened with nuts 15 from the outside.

Therefore, the bottom surface of the base brick 10 has a band-shaped protrusion 2 a
, 2a, but the center part thereof sag under its own weight, so the base brick 10 has this supporting rod 14 in addition to the band-shaped protrusions 1a, la, )a, 2a described above.
This is partly supported by ,...

By the way, the purpose of firmly fixing the stand brick 10 with the frame A in this way is to place various types of burnt objects 12 on top of it, and to transport it to various locations and process it as a single unit. For convenience, this frame A is designed to be suitable for conveyance on a roller conveyor.

As a specific structure for this purpose, first, both the long sides 1, 1 and the short sides 2, 2 have a considerable protrusion at their lower end portions, that is, the short sides 2, 2 have a hinge 3... The thickness U of ... and the support rod 14 that is hung between the long sides 1 and 1...

6, 16, 17, and 17 are provided.

Note that the nuts 15 are fitted into the portions of the support rods 14 that protrude from the short sides 2, 2, so the outer protrusions 16 and 16 on this side Since it would be a problem if the nuts 15 cannot be fully fitted due to the existence of the outer projections 16.16, the nuts 15...
Taking into account the fitting allowance for..., hole 13...
Make sure that it protrudes from a considerable distance below.

Next, the lower end surfaces of these four outward projections 16, 16, 17, and 17 are made smooth and flush.

Therefore, normally, a means for inserting the fork of the lift is provided on the long sides 1, 1 of these parts, but in this invention, the means for inserting the fork of the lift is provided in the insertion hole 18...
Do not use cutouts or other measures that would prevent the bottom surface from being flush.

In addition, for lifting with a crane, the outer protrusion 1
7. Since the bottom surface of the 17 is not modified in any way, a normal hook 19 etc. may be provided.

Also, one of the long sides 1, 1 has a parting point, so the outward protrusion 17 is not continuous at this part. A wire 21 is removably provided so as to be flush with the lower surface of the outer protrusion 17.

There are various ways to think of this specific precept, but for example,
It is conceivable that a flat plate 22 with its lower surface flush with the other surface is attached from the outside when necessary, and is dried with a bolt 23, 23, etc. (see Fig. 1).

In addition, it is also possible to always fix one end of the flat plate body 22 to one of the outer protrusions 17 with a hinge or the like, and when necessary, pass it to the other outer protrusion 17 and fix it. In this case, , its fixing operation is easy.

In the above, when the wire 21 is attached to the outer protrusion 17, it is preferable that the outer end surface thereof is the same or lower than that of the outer protrusion 17.

As described above, this invention has the following functions and effects.

That is, once the base brick 10 is fixed using this frame A, it is placed on the roller conveyor 24 and conveyed thereon. At this time, the outer protrusion 16 at the lower end of the frame A
, 16, 17, and 17 are all smooth and flush, so each roller 25 of the roller conveyor 24...
...it slides smoothly over the top.

Normally, the empty arrow part 20 would exist at a certain point on the long side 1, and a large vibration would be generated at this point, but in this invention, the lower surface of this part is connected to the lower surface of the other outward protrusion 17. Since a flat wire 21 is wired, there is no void portion 20 and there is no deterioration in smoothness.

Since the wire 21 is detachably attached, it does not obstruct the operation of attaching and detaching the frame A to the base brick 10 in the slightest.

Furthermore, when many frames A are conveyed continuously on the roller conveyor 24, each frame A is inevitably connected, but at this time, the outer protrusions 16, 16, 17, 17 Since T and T' are the largest of the peripheral attachments of the frame A, the outer end surfaces of the connecting pieces 16, 16, 17, and 17 are in contact with each other. Therefore, even if it has conveying power, it can be used effectively.

That is, when the longitudinal direction of the frame A is taken as the transport direction, the protrusion T of the outer protrusion 16. ... is larger than the protrusion length ■, the outer end surfaces of the outer protrusions 16 and 16 of the adjacent frame A are in contact (see Fig. 3), and each of When the frames A are lined up in a connected state and conveying force is applied, it will act at right angles to the adjacent ones.

Similarly, when transporting the frame A in the transverse direction, the protrusions T' of the outer protrusions 17 and 17 located at the front and rear are
This outward protrusion 1 of the adjacent frame A is larger than half of the thickness U of ... and the protrusion length W of the flanges 5, 5.
The outer end surfaces of 7.17 are in contact with each other (see Figure 4).

Since the outer end surface of the transfer money 21 is the same as or lower than the outer end surface of the outer protrusion 17, the outer protrusion 17 located in front and rear
．． 17 does not impede the parallel contact property with each other in any way.

In addition, both the long sides 1 and 1 and the short sides 2 and 2 that make up frame A,
Thick outer protrusion 16, 16, 17.1 at its lower end
7, the rigidity increases accordingly, and the strength is also improved.
