The front end edge 7b of the pedal 7 is a bottom plate 7
With respect to c, it is attached so as to be tiltable by a hinge 20, and possesses an elastic force that pulls the rear end edge 7a of the pedal 7 upward between the rear end edge 7a of the pedal 7 and the horizontal rod 21 installed on the first support column 1. Suspend the spring 9.

Below the arm 10, a first roller core is provided.
When the bearing 4 is rotated and tilted, it is returned obliquely downward to the component supply side (c) through the space (d) through which the empty container (b) sliding down from the first roller conveyor 4 can pass. The roller conveyor 11 for use is installed from the second support pillar 2 to the third support pillar 3. The bottom tip of the return roller conveyor 11, when the first roller conveyor 4 is Mawarido downwardly inclined, rear edge 4 of the first roller conveyor 4
A bottom edge 4a of b is projected to form a receiving edge 22 for preventing the first roller conveyor 4 from rotating, and a rear end is provided with a stop edge 23 for preventing the empty container (b) from sliding down. To do.

The support frame 6 is not limited to the rectangular frame of the embodiment, but as shown in FIG. 3 , the front and rear parts of the rod 24 are bent inward to form the support parts 24a and 24b. Form a pair left and right
Opposite the support portion 24a, 24b of the rod 24, 24 of
And is disposed on the left and right second support columns 2 and is symmetrically supported by the shaft 16, and supports the left and right rods 24, 24 respectively.
The bottoms 4a and 5a of the first roller conveyor 4 and the second roller conveyor 5 may be supported by 4a and 24b.

[0013]

Since the present invention is constructed as described above, when the container (b) containing the component (a) is placed on the second roller conveyor 5 from the component supply side (c), the container (b) Is a group
Moving on the first roller conveyor 4 from above the second roller conveyor 5 which is inclined obliquely downward toward the standing worker ,
The front lower corner edge (e) of the container (b) hits the front stop edge 15 of the first roller conveyor 4 and stops . Second roller comb
The subsequent container containing the parts placed on the 5th roller is the first roller conveyor.
On the 2nd roller conveyor 5
In to stop. The inclined states of the first roller conveyor 4 and the second roller conveyor 5 are the same as those of the support frame 6 and the arm 10.
It is supported by the tip portion 10a (FIG. 1) .

After the assembling operator takes out the parts from the container (b) on the first roller conveyor 4 and empties them, the pedal 7
When is depressed against the elasticity of the spring 9, the rear edge 7a is lowered around the hinge 20. Along with that, the wire 8 locked to the rear end edge 7a is pulled downward, and the front portion 6c of the support frame 6 that locks the starting end 8a of the wire 8 is pulled downward so that the support frame 6 is centered on the shaft 16. Rotate around.

At the same time, the rear portion 6a of the supporting frame 6 rotates upward and pushes up the bottom portion 5a of the front portion 5b of the second roller conveyor 5, so that the front portion 5b is displaced upward and the rear edge 13 is lowered.
The second roller conveyor 5 tilts about the shaft 12 so as to be displaced toward the left side, but the rear lower corner edge (f) of the container (b) placed later is prevented from moving because the rear lower corner edge (f) is blocked. <br/> It won't drop (Fig. 2) .

[0016] On the other hand, since the front 6c of support frame 6 Waso which was led to the wire 8 is displaced downward, <br/> first roller conveyor 4 lost support of support frame 6 rests with its own weight Empty container load
And the rear edge 4b of the first roller conveyor 4 is downward.
And the front stop edge 15 is rotated and tilted so as to be displaced upward . Therefore, the empty container starts sliding on the first roller conveyor 4, the rear edge 4b of the first roller conveyor 4 hits the receiving edge 22 of the returning roller conveyor 11, and the rotation of the first roller conveyor 4 is prevented. It stops, but the empty container (b) is further
Continue to slide and move on the returning roller conveyor 11 through the space (d) between the supporting frame 6 and the returning roller conveyor 11 ,
We stop at the stop Tomeen 23.

At this point, when the stepping pressure on the rear end edge 7a of the pedal 7 is released, the rear end edge 7a of the pedal 7 is pulled up by the elastic force of the spring 9, so that the wire 8 that has been pulled loosens. On the other hand, the rear portion 6a of the support frame 6 is the second roller.
The bottom part 5a of the front part 5b of the conveyor 5 was pushed up,
Since the load of the container (b) containing the component (a) on the second roller conveyor 5 is applied to the portion 6a , the support frame 6 is attached to the shaft 1
Reverse around 6. Since the supporting frame 6 returns to the old position, the starting end 8a of the wire 8 is displaced upward. The wire 8 is pulled and pulled to the old state, and the front portion 6c of the supporting frame 6 rotates upward.
While pushing up the rear end of the first roller conveyor 4, the rear part 6a of the support frame 6 hits the front end 10a of the arm 10 to rotate.
The movement stops and returns to the old position. For this reason, the support frame 6 forms the bottom portion 4 a of the first roller conveyor 4 and the bottom portion 5 of the second roller conveyor 5.
Contacting a, they are lined up on the same inclined line (S) again and kept in the inclined state.

Then, the succeeding container (b) containing the component (a) on the second roller conveyor 5 is the same as that described above for each member.
By the action, to move the first roller conveyor 4 above, the front bottom edge rim of the container (B) (E) stops against the front stop edge 15 of the first roller conveyor 4. On the other hand, the return roller conveyor 11 an empty container (b) places the component to replenish been <br/> Eject at the component supply side, the container (B) in the human
When it is placed on the second roller conveyor 5, it stops by hitting the container (b) containing the component (a) that has been moved on the first roller conveyor 4. After that, for the pedal of the assembler
By repeating the operation of pressurizing and releasing, similar to the above for each member
By the action, the supply of parts is continued and the product is assembled.

[0019]

As described above, according to the present invention, the assembling operator does not perform the operation after the parts are taken out from the container on the first roller conveyor.
Since the empty container can be automatically slid back onto the return roller conveyor in a short time by only stepping on the dull , the assembly operator holds the empty container in his hand and places it on the return roller conveyor. Since no manual work for moving is required, both hands can be exclusively used for assembling the product, so that work efficiency can be improved. Also, while the empty container is automatically returned by the movement of the foot, the subsequent container containing the parts is in the second row.
Automatically moves on the first roller conveyor from the Rakonbea
And because it is supplied to the assembler side, immediately replenished parts <br/> article taken out from the container can move on to the next assembly operation, I required coupled with the movement manually empty container Work can be done quickly and efficiency can be further improved. Change
, The container containing the parts is placed on the first roller conveyor.
Sometimes the container is assembled with the first roller conveyor
Since it is tilted toward, it is easy to remove parts from the container
The work efficiency can be doubled.
