Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a transportation system in which, for example, marshalling boxes (distribution boxes) loaded with a set of electrical parts, mechanical parts, etc. are connected and transported. This invention relates to a marshalling box conveying device.

[Technical background of the invention and its problems]

As shown in FIG. 5, a conventional marshalling box body has an outer frame 1 made of plywood and an inner box 2 made of a foamed resin material, and the shape and shape of each part 3 made of each mechanical component are fitted into the inner box 2. Recesses 4 are formed to match the size, and each part 3 is inserted into each recess 4.

In this way, the marshalling box described above is
On the automatic assembly line, mechanical parts and electrical parts for one set of equipment to be assembled are loaded all at once, and each marshalling box is transported by a conveyor on the automatic assembly line.
Each part 3 loaded into the marshalling box body is attached to a machine frame by a robot on an automatic assembly line.

However, the above-mentioned marshalling box not only generates wood chips from the outer frame 1 made of plywood during transportation, but when the number of parts of the equipment to be assembled increases, it is impossible to store them in one marshalling box. First, at least a plurality of marshalling boxes are required. However, when multiple marshalling boxes are placed on a conveyor and transported, it is difficult to separate and transport one set of parts, and furthermore, it causes confusion during assembly on an automatic assembly line. Not only is there a risk, but
When assembling different types of equipment with different outputs and capacities, different parts are required for part of one assembly, so it is necessary to prepare them in advance as parts to be loaded into the marshalling box. There are other difficulties.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and is designed to separate and transport one set of parts in an automatic assembly line, and to handle changes in model or different types of equipment. The purpose of the present invention is to provide a marshalling box conveying device that facilitates the transportation of parts during assembly, and also improves the workability and compatibility of different types of assembly work.

[Summary of the invention]

The present invention provides a conveyor equipped with a plurality of engaging protrusions in an automatic assembly line, in which the engaging protrusions are provided so as to engage positioning holes in a base pallet, and a pair of positioning pins are planted diagonally on the base pallet. and each of the engaging holes of the marshalling box body made of a foamed resin material is removably provided on both positioning pins, and a hook member having a hook portion at the front part of the base pallet is arranged perpendicularly to the conveyor. Moreover, the base pallet is slidably provided, and a locking pin is provided at the rear of the base pallet so as to engage with a hook member of another base pallet that follows.

[Embodiments of the invention]

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

1 to 3, reference numeral 10 denotes a conveyor in an automatic assembly line. On this conveyor 10, each flattened rectangular base pallet 11 is placed. A pair of positioning holes 12 are provided on the top.
are drilled, and these positioning holes 12 are connected to each engaging protrusion 10a attached on the conveyor 10.
It is becoming more and more engaged. Further, a ridge 13 is attached to the front portion 11a of the base pallet 11, and a hook portion 14a is provided within the ridge 13.
A hook member 14 is provided perpendicularly to the length direction of the conveyor 10 and is slidable. Furthermore, the length of this hook member 14 is formed longer than the width of the base pallet 11, and one end portion 1 of this hook member 14 is formed to be longer than the width of the base pallet 11.
4b projects slightly laterally from the base pallet 11. Furthermore, a pair of positioning pins 15 are implanted in opposite positions of the positioning holes 12 of the base pallet 11, and both positioning pins 15 are attached to a mark made of a foamed resin material placed on the base pallet 11. Shearling box body 1
It is adapted to be engaged with an engagement hole 16a bored in the bottom of 6. Further, a locking pin 17 is implanted in the rear portion 11b of the base pallet 11, and the hook portion 14a of the other base pallet 11 is engaged with the locking pin 17.

Note that the marshalling box body 16 is formed with concave portions 16b for storing various parts.
The parts loaded in b are arranged based on the assembly order of the automatic assembly line. As shown in FIG. 4, some of the marshalling box bodies 16 are formed with recesses 16b for storing elongated parts.

Furthermore, since the marshalling box body 16 has recesses formed in the shapes of the parts to position each part, the robot arm of the automatic assembly line can directly grab the parts from the marshalling box body 16. ing.

Therefore, in the automatic assembly line, each base pallet 11 is placed on each engagement protrusion 10a of the conveyor 10, and then one end 14b of the hook member 14 is pushed sideways. The hook portion 14a of the hook member 14 engages with the locking pin 17 of the other base pallet 11, thereby connecting each base pallet 11, and
Each of these base pallets 11 is transported by a conveyor 10.
and will be transported as one. Each of the marshalling boxes 16 is placed on each base pallet 11, and each positioning pin 15 of each base pallet 11 is engaged with each engagement hole 16a of each marshalling box 16. This prevents the robot arm from accidentally grabbing a part because it does not move accidentally and cause misalignment.

〔Effect of the invention〕

As described above, according to the present invention, in a conveyor provided with a plurality of engaging protrusions in an automatic assembly line, the engaging protrusions are provided so as to engage with the positioning holes of the base pallet, and A pair of positioning pins are implanted in the base pallet, each engagement hole of the marshalling box body made of a foamed resin material is removably provided on both positioning pins, and a hook member having a hook portion at the front part of the base pallet is connected to the conveyor. In the automatic assembly line, the latch pin is provided at the rear of the base pallet so as to engage with the hook member of the other base pallet that follows. By simply replacing the marshalling box mentioned above, you can not only freely change the parts transfer procedure when changing models or assembling different types of equipment, but also facilitate the workability and compatibility of different types of assembly work, and facilitate mass production. It is possible to save labor by Further, the present invention has excellent effects such as being able to freely remove each base pallet from the conveyor and also being able to selectively connect each base pallet to each other as necessary.
