Description

[Detailed explanation of the invention] In conventional chain conveyor frames, each member such as the rail receiver, rail, stay, etc. is processed by drilling, batten welding, etc., then painted, and the bolts and
It is assembled using nuts, and for example, as shown in Fig. 4, a rail holder d is fixed to a rail c of a conveying chain b that carries a conveying pallet a and moves forward.
are attached to the top, bottom, left and right of each stay e, which is the horizontal member of the frame, in preparation for the circulation movement of chain b.
Attach the frame side frame f, which serves as the guiding edge of the pallet a, to the end of the stay e, and attach the stay e to the leg g.
Since it is fixed on the top, the assembly work as a whole requires a considerable amount of effort.

In view of the above-mentioned defects, this idea was developed by forming the rail receiver of the forward moving part (conveyance side) and the rail receiver of the backward moving part vertically and integrally with the frame side frame from light metal as an extruded material. , the rail insertion groove and the bolt and nut mounting parts are integrally formed as slide grooves at the same time, making the assembly process easier by eliminating any drilling work, etc., and making it possible to reduce the weight of the aircraft. This is an improved version.

To explain the drawings below, in FIGS. 1 and 2, reference numeral 1 denotes a rail receiving member having a deep gutter-shaped cross section and having a partition-like upper floor 2 formed therein. In this way, the rail receiving material 1 has a corner between the above-mentioned partition-shaped upper floor 2 and its lower floor 3, which is surrounded by the outer plate 4 and the inner plate 5 that rise at both ends of the lower floor 3. A rail receiving part 7 for the backward movement of the conveyor chain 6 is formed which is closed in a cylindrical shape, and the upper surface of the upper floor 2 is open, and a rail receiving part for the forward movement of the chain 6 is closed on both sides by the inner and outer plates 5 and 4. so that part 8 is formed. The upper end 9 of the inner plate 5 of the rail receiving material 1 is connected to the pallet 1 placed on the conveyor chain 6.
0, but the outer plate 4 is made moderately higher than the upper end 9 of the inner plate so as to serve as a guide edge for the pallet 10, and the hollow frame side frame 11 is integrally formed toward the outside. This increases the strength of the rail receiving material 1 and improves the appearance at the same time.Furthermore, a flat portion of the upper surface 12 of the frame side frame 11 is formed on the upper part of the outer plate 4. Make 13 round to make it easier to touch.

At the center of the upper floor 2 and lower floor 3 of this rail support material 1, a rail insertion groove 15 for holding a chain lever 14 having a convex cross-sectional shape by inserting it from one end is integrally projected from the floor part. It is formed by protrusions 16, 16 with a hook-shaped cross section, and protrusions 17, 17 with a hook-shaped cross section are provided oppositely on the lower surface of the rail receiving material 1, so that the width of the mouth part of the groove is narrow and the inside thereof is wide. The slide groove 18 for bolt insertion is integrally formed so that the bolt can be tightened onto the base leg 19, and each of these parts is integrally made of extruded light metal or light alloy material as shown in Fig. 2. It is to be formed. The chain rail 14 is made separately from synthetic resin (or may be made of metal) so that it can be inserted into the insertion groove 15 from one end.

In addition, an accessory hook 20 is attached to the outer surface of the frame side frame 11 to facilitate hanging tools, etc., and an opening is provided in which the head of a bolt 21 can be inserted. A slide groove 22 is formed with a narrow width and a wide interior. In addition, a slide groove 23 for bolt insertion of a similar shape is provided on the inner surface of the frame side frame 11 on the opposite side to this slide groove 22, and when a roller row is provided at the end of the conveyor, the roller bearing can be used. Can also be equipped to install. In this case, since the slide grooves 22 and 23 are opposite to each other, a connecting member 24 with a horizontal H-shaped cross section is integrally extruded and formed on the frame member with a gap that allows the bolt head to fit into the frame side frame 11. The upper half is firmly connected to the lower half. Note that the conveyance chain 6 is not limited to the type shown in FIG.
For example, it is also possible to use a top plate type or the like to place objects to be transported as shown in FIG.

In this invention, as mentioned above, only the upper forward movement rail receiving part 8 has an open top surface, and the backward movement rail receiving part 7 below it has the upper and lower floors 2, 3, the inner and outer plates 5,
4 to form a rectangular tube shape, a hollow frame side frame 11 is integrally formed on the outside of the outer plate 4, and a slide groove for bolt insertion is formed on the lower surface of the lower floor 3. Since the protrusions 16, 16 having a hook-shaped cross section and forming the part 18 are provided so as to protrude integrally with the floor part,
The cross-sectional shape of the rail support material 1 is extremely strong against bending forces to which the support material 1 is subjected. Therefore, when constructing a conveyor frame using this rail support material 1, the arrangement span of the pedestal legs 19 that receive it can be made larger than that of the conventional one, and the number of pedestals can be reduced. The joints between the rail receivers 1 can be made by simply butting their end surfaces together on the base leg 19, and in this case, the bolts to the base leg 19 can be tightened by inserting the heads of the mounting bolts into the slide grooves 18 in advance. The bolt can be mounted by moving it along the slide groove 18, aligning it with the bolt insertion hole provided in the base leg 19, and tightening the nut, so that the mounting work is extremely easy. Moreover, since the rail support material 1 is entirely made of light metal and is an extruded material, it has been surface-treated (anodized, colored alumite), so there is no need for painting, and there are fewer parts required to install a conventional rail support. No stay member is required, and the cost is low. In addition, it is lightweight and reduces the burden on structures such as building floors and beams when installed, and at the same time, since it is a non-ferrous metal and non-magnetic material, it can be used as a conveyor for assembly and adjustment of TVs, videos, etc. that are easily affected by magnetism. It is suitable as a frame, and since the rail support material 1 has two rails facing each other as shown in FIG. In addition to preventing this, the frame looks good in appearance, and it is also convenient to attach the accessory rack 20 at a necessary location. Note that since the rail 14 is supported by being inserted into the insertion groove 15 from one end, there is no need for screwing, etc., and the elongation of the rail 14 due to the influence of temperature changes is absorbed to prevent the rail from lifting or deforming. In addition, the rails are easy to replace when they wear out, and if the rails 14 are made of synthetic resin, noise can be reduced, making it extremely effective as a conveyor frame. .
