Description

[Detailed Description of the Invention] This invention relates to a device that automatically carries articles into or out of article receiving jigs installed at predetermined intervals on an endless chain conveyor.

Conventionally, in order to process items such as connecting rods and connecting rod caps with a broach machine, item receiving jigs were installed at predetermined intervals on an endless chain conveyor, and items were manually loaded and unloaded one by one. .

In addition, one possible method for automatically loading or unloading is to load or unload at a fixed timing, but in this method, the intervals between article receiving jigs attached to the chain conveyor at predetermined intervals vary depending on the elongation of the checker 7. However, since there were some variations in the moving speed, it was difficult to carry in or out reliably.

This invention was made to solve these conventional problems, and it is possible to reliably carry articles into and out of the article receiving jig despite fluctuations in the interval between the article receiving jigs and changes in moving speed. It has been made possible.

In other words, in this invention, a plurality of article receiving jigs are provided at predetermined intervals on an endless chain conveyor, and articles are placed on the article receiving jigs and transported, and each article receiving jig is equipped with a cam. and an article clamping portion at the tip thereof, which is capable of reciprocating between an article mounting table disposed above the conveyor and an article receiving jig at the position, at least one of the receiving position and the taking-out position of the conveyor. a sliding member disposed in contact with the cam surface of the cam so as to be able to reciprocate, and the sliding member and the arm are connected so that the arm reciprocates in accordance with the movement of the sliding member. A moving mechanism having a link is provided, and is configured to sequentially carry in or carry out articles in accordance with the movement of the article receiving jig.

Examples of this invention will be described below with reference to the drawings.

FIG. 1 shows the overall configuration of the device. Article receiving jigs 2 are mounted on the endless chain conveyor 1 at predetermined intervals, and the article receiving jigs 2 are provided with a cam 21 and an article holding part 22. .

A carry-in device 10 is disposed at the article receiving position, and the carry-in device 10 automatically carries articles 3 such as connecting rod caps into the article receiving jig 2 which moves at a constant speed.

Then, the article 3 is conveyed while being held by the article holding part 22 of the article receiving jig 2, and on the way, the broach cutter 1
1, then further conveyed, and taken out at a take-out position (not shown).

The carrying device 10 includes an arm 5 that moves along a guide 7;
A sliding member 34 that moves up and down by the cam 21 and an arm 5
and a link 4 that connects the sliding member 34, and the link 4 swings about a shaft 40 to connect the sliding member 34.
The vertical movement of the arm 5 is transmitted to the arm 5.

While the arm 5 moves along the guide 7, it picks up the article 3 on the article mounting table 90 and transfers the article 3 to the article holding part 22 of the article receiving jig 2.

As shown in FIGS. 2 and 3, the articles 3 are fed one by one onto the article mounting table 90 through the supply path 92, and are held by a pushing member 95 attached to the tip of the rod 91 of the cylinder 9.
It is made to push out one by one to the delivery position of the tip.

The article 3 moves to the delivery position at the tip while its posture is corrected by the rails 93 and outer wall 94 of the article mounting table.

Further, the arm 5 has a main body 8 that is slidably fitted into the guide 7.
is held via a holding arm 51, and a rod 62 of a cylinder 60 attached to a bracket 61 fixed to the main body 8 is connected to this holding arm 51.
2, it is configured to be able to move up and down.

The holding arm 51 is a guide plate 83 fixed to the bracket 61.
．． It is sandwiched between 83 and can only move up and down.

The main body 8 is provided with a protrusion 81, and the protrusion 81 is connected to the link 4 by fitting into the notch 41 of the link 4.

Further, the arm 5 is provided with a cylinder 50 at the upper part, a notch 57 is formed in the sliding member 56 at the tip of the rod 52, and a link 54 rotatable around a shaft 53 at the side thereof.
One end portion of the notch portion 57 is fitted into the notch portion 57 .

In addition, a horizontally movable chuck 5 is provided below the link 54.
5 is arranged, and the other end of the link 54 is fitted into the groove 59 at the upper part thereof.

Therefore, when the cylinder 50 is actuated to pull up the sliding member 56, the link 54 engaged therewith rotates around the axis 53, thereby moving the chucks 55 toward each other and clamping the article 3 at the lower part. .

To release the clamped article, the operation in reverse to the above may be performed.

As shown in FIG. 4, the sliding member 34 vertically slidably passes through the holding member 32 fixed at an appropriate position.
A downward force is applied by a spring 35, and a roller 33 is provided at the lower end to move on the cam surface of the cam 21, and a projection 31 is provided at the upper end to connect it to the elongated hole 42 of the link 4.
It is movably fitted inside.

Next, the operation of this device will be explained.

The article receiving jig 2 is moved by the chino 1, and when the article receiving jig 2 reaches the position of the carry-in device 10, the roller 33 comes into contact with the cam surface of the cam 21, and the sliding member 34 is moved against the force of the spring 35. Push up.

When the sliding member 34 rises, the link 4 rotates clockwise around the shaft 40 due to the engagement between the protrusion 31 and the elongated hole 42, and the main body 8 is guided by the guide 7 via the protrusion 81 at the other end of the link 4. descend along the

Note that when the article 3 is sent to the delivery position at the tip of the article placement table 90, this is detected, the cylinder 50 is activated to hold the article 3, and the cylinder 60 is activated to raise the arm 5. .

That is, since the arm 5 has already moved up a little while holding the article 3 from the position shown in FIG. Move to section 22.

When the roller 33 reaches the top of the cam 21, the article 3 is transferred to the article holding section 22, and the clamping by the chuck 55 is released by the action of the cylinder 50.

When the roller 33 passes the top of the cam 21, the sliding member 34 is lowered by the force of the spring 35, thereby causing the link 4 to rotate in the opposite direction and causing the arm 5 to rise along the guide 7.

During this time, the article receiving jig 2 holds the article 3 and the carrying-in device 10
Move from the position to the left in FIG.

In this way, the cam 21 and the sliding member 3 are attached to each article receiving jig 2.
4. Since the article 3 is carried in by link 4 and arm 5, there is an influence due to changes in the interval between article receiving jigs 2 due to elongation of chain 1, etc., and fluctuations in the moving speed of article holder 2. Therefore, the article 3 can be carried in reliably.

Note that the sliding member 34 that has descended at this time is arranged in a positional relationship such that it does not hit the article holding section 22 and the article 3 held therein.

After loading an article into one article receiving jig 2, the loading device 1 is loaded until the next article receiving jig 2 reaches the position of the loading device 10.
The following operations are performed within 0.

That is, when the article 3 is carried out from the tip of the article mounting table 90, the article supply path 9 is opened by the operation of the cylinder 9.
The article 3 supplied from 2 is moved to the tip of the article mounting table 90 by the pushing member 95.

Further, the arm 5 that has ascended obliquely to a predetermined position along the guide 7 is lowered slightly downward by the cylinder 60, and after the cylinder 50 is operated and the chuck 55 grips the article 3 on the article mounting table 90, the arm 5 is moved to the predetermined position. Then, the operation by the cam 21 is repeated as described above.

The basic idea is the same at the take-out position where the article is taken out from the article receiving jig as at the above-mentioned carry-in position.
It is also possible to arrange the carry-in device at the take-out position and use it as a carry-out device.

Further, the transfer device can also be configured as shown in FIG. 5, for example.

Naturally, the unloading device shown in FIG. 5 can also be used as a loading device.

Next, this unloading device will be explained.

The holding mechanisms of the cylinder 50, arm 5, and chuck 55 are the same as those of the carrying-in device described above, but the loci of movement of the main body 8a and arm 5 are different.

The main body 8a is slidably attached to two horizontal rails 71.71 provided on the fixed base 70.
Guide plates 83, 83 facing each other at a constant interval are attached to the bracket 61 provided at the holding arm 51.
is held between the guide plates 83, 83 so as to be able to move only in the vertical direction.

Although not shown in the drawings, such a holding means may be a so-called dovetail fitting means extending in the vertical direction.

Further, a shaft 75 is made to protrude from the arm 5, and one end of this shaft 75 is movably fitted into a groove 73 formed in the fixed plate 70.

FIG. 5 shows a state in which the arm 5 is lowered. In this state, when the article 3 on the article receiving jig 2 reaches the position of the chuck 55, the article 3 is grabbed by the operation of the cylinder 50, and at the same time, the cam 21 is activated. As a result, the link 4 rotates clockwise, and the main body 8a is moved along the rail 7 to the left in FIG. 5 via the protrusion 81 provided on the main body 8a.

This pushes arm 5 in the same direction, but arm 5
Since its shaft 75 fits into the groove 73 and is movable up and down, the shaft 75 moves along the groove 73, and therefore the arm 5 moves along the shape of the groove 73.

The raised arm 5 transfers the article onto an article placement table (not shown), and as the sliding member descends beyond the top of the cam 21, the link 4 rotates counterclockwise, causing the arm 5 to move along the groove 73. It is lowered and returned to the state shown in FIG. 5, and is ready to hold the next article 3.

As explained above, this invention is designed to automatically load or unload articles into or out of the article receiving jig installed on the endless chain conveyor, and each article receiving jig can be loaded or unloaded separately. Since the device is operated, it is not affected by the stretching of the chest, etc., and items can be carried in or out without fail.
