The present invention is a feeder (FEEDER) for sorting and feeding the various parts required for the assembly of the automated assembly line, in particular, in order to accurately supply the component member guided in the feeder to the robot chuck to form a member alignment guide without twisting An apparatus for straightening a member posture of an IN LINE FEEDER for correcting a posture of an alignment member to be guided vertically.

As is well known, as the industry develops, automation lines are widely applied in high precision parts supply systems such as machining lines, assembly lines, automobiles, and electric machines for productivity, labor costs, precision, and speed.

In such an automation line, assembly is provided by sequentially supplying bolts and nuts for fastening parts to moving assemblies and moving assemblies along the line.

At this time, the fastening bolts, nuts, etc. are supplied while being aligned by the supply magazine and the feeder, the supply member is made of a process of being fastened to the assembly member moved by the robot chuck.

Such a feeder is a straight feeder comprising a guide stairway in a circular container, a bowl feeder (BOWL FEEDER) provided as a guide and a drum obliquely hinged, and a guide guide on the inner surface of which is exposed to the outside. IN LINE FEEDER).

The straight line feeder in the above-mentioned automation line has a member selection tube containing a nut bolt, which is a small member filled with a hopper as hesitant, and the receiving member rotates the drum so that the housing member is arranged like the selection line in the alignment guide guide in the drum. It is configured to transfer the alignment, the member to be conveyed is supplied to the assembly line by the guide guide or intermediate transfer to the assembly line by the robot.

In such a linear feeder, the volume is very small and the members of various shapes are moved to the guide guide, but there are frequent problems that the linear feeder cannot be accurately supplied to the robot chuck due to the vibration of the straight feeder itself and the failure of the guide. The guide guide is horizontal in the drum but twisted vertically at the end to mediate the member to the robot chuck.

That is, as shown in FIG. 1, the drum installed obliquely and the guide guide formed from the drum are laid in an oblique state to induce an effect such as the feeding force and alignment of the guide member.

In this configuration, the conveyed member is moved to an oblique position according to the guide guide and when the robot chuck is supplied to the robot chuck, the robot chuck cannot make accurate contact with the supplied member by reciprocating horizontally or vertically so that the robot chuck can pick up the member. We cannot mediate by none. In order to remedy this disadvantage, in the known art, the guide guide is twisted by twisting to keep the end portion horizontally, such as a robot chuck, and the member transferred by the twist is moved along the twisted guide guide to be positioned horizontally at the end. By modifying it, it maintains the same level as the robot chuck.

In this twisting configuration, the movement of the member is incomplete in the torsional portion, and thus the transfer failure of the member and the interruption of the transfer and the twisting of the guide are caused.

In this way, when supplying the member from the feeder, which is a member supply means, or incorrectly supplying the member to the robot, it causes a lot of economic damage such as causing damage to the entire assembly line and degrading the quality of the product. Will be.

In another design of the present inventor for correcting such a closed end, the robot constitutes a mediation means for reciprocating the position of the robot feeder and the robot chuck, and the robot aligned when the suction hand of the mediation means rotates the member aligned with the guide of the feeder. The chuck can be fed to the assembly line by intermediary to improve the inaccurate mediation in the feeder. In another feeder, another intermediary feeder, the member takeout device, is used to align and move the member to the end of the guide. It can be seen in other applications of the present inventors that the robot chuck of the automation line can be supplied and transported by the member accurately and quickly.

The above drafts relate to a bowl feeder, but the present invention relates to a straight feeder. In particular, the straight feeder is a member in which the selection guide and the alignment guide guide formed in the drum fall when the member is dropped from the diagonally installed drum. It receives and selects and aligns and transfers it to the guide.

At this time, the guide is configured to extend the guide in a diagonal of about 45 degrees from the vertical to align the transfer member.

This is because when it is configured at right angles, the alignment and alignment of the members are difficult and cause a lot of side effects in the transfer, and when it is horizontal, the members are diagonally formed due to the problem of the member being separated from the guide.

Accordingly, as the guide guide, the drum side is configured to be inclined about 45 degrees from the body, and at the intermediate point of the end, it is erected vertically so as to be level with the robot chuck. Therefore, the guide is configured to twist the angle of inclination at the center portion to adjust the guide feed hole vertically from the diagonal.

The conventional improved straightener is entangled in the twisted portion, that is, the torsional portion, as the conveying member is guided by the guide guide, or breakage or failure of the feed failure.

That is, in the twisted portion, the transfer hole of the guide guide is not maintained at regular intervals, and the member is aligned and transferred by the load due to the increase in friction that cannot have a constant transfer force in the member and the member transferred to the member slide. Pressure between the members causes entanglement or poor transfer.

In addition, since there is no drawing means at the end of the guide, the transferred members are not in the correct position, and entanglement of the members occurs, which causes the disadvantage that the robot chuck cannot accurately fix the transferred members.

The present invention has been devised to correct such a disadvantage of the conventional straight straighter, in the straight line and alignment transfer guide guide 30 of the member to configure the entire guide guide in a horizontal or oblique diagonal without twisting the falling member Receiving the fixed and aligned transfer to improve the problem in the transfer,

By standing the posture of the member conveyed at an oblique angle by the right position at the correct position in a separate posture correcting unit, the robot arm 3, which is a later work, can accurately withdraw the conveying member 4.

Therefore, the present invention is that the supply member 4 is aligned at the correct position and the guide guide 30 is provided horizontally or diagonally without twisting, so that the conveyance of the guide member is easy and the member can be accurately supplied to the assembly line. It was devised by

When the configuration of the present invention as described in detail by the accompanying drawings as follows.

1 is a perspective view showing the whole of the present invention, and FIG. 2 is a cross-sectional view of the main part of the present invention, and FIG. 3 is a diagram illustrating the operation of posture correction.

As shown in the figure, the drum 20, which is rotated by the power unit, is installed at an angle to the base 10, and the member guide guide 30 fixed to the vibrator unit 11 protrudes in the drum 20 for a long time. In a known linear feeder configured to allow the members in the drum 20 to be aligned and transported along the guide guide 30,

The guide guide 30 is configured at an integral diagonal without twisting,

A support body 40 fixed to the base 10 is formed to drive the shaft 42 interlocked with the power means 41 to interlock the pinion 43, and the pinion 43 has a sector gear 44 attached thereto. By interlocking with each other, the upper and lower reciprocating sector gears 44 are integrally formed with the member conveying member 45 constituting the member inserting recess 50 so that the member inserting recess 50 of the member conveying member 45 is oblique. The guide guide 30 of the position is configured to reciprocate between the discharge groove 31 and the position perpendicular to the gas.

Reference numeral 46 denotes a sector gear and a moving distance adjusting nut, 47 a stopper, 2 an assembly line, 3 a robot arm, and 4 a member.

Referring to the present invention configured in this way as described in detail the operation effect as follows.

1 is a perspective view of the present invention and a cross-sectional view of the operation description cut out the main portion of the present invention of Figure 2, Figure 3 is a view illustrating the operation of the present invention as shown in FIG. When the member 4 is supplied to the drum 20 by the hopper, the linear feeder supplied with the member 4 rotates the drum 20 as known.

At this time, the members 4 accommodated in the drum 20 are dropped from the upper portion to the lower portion as the upper portion is transferred from the lower portion to the upper portion by the transfer pieces formed on the drum inner circumferential surface of the guide guide 30. Falling to the selection line and the alignment piece and they are moved to the discharge side of the guide guide 30 while being guided along the transfer groove of the guide guide 30 as known.

The member 4 is moved by the guide guide 30 and its conveying groove is a straight line, that is, a straight line diagonally in the body, so that the member 4 during the transfer is not subjected to the load by the twisted portion of the guide guide 30, etc. The transfer is smooth and the alignment is easy.

As a result, when the end of the guide guide 30 is reached while being aligned with the guide end discharge groove 31, the member transfer member integrally formed on the sector gear 44 in close contact with the end of the guide guide 30 as shown in FIG. 3a. 45 and the member 4 conveyed to the member insertion recess 50 are inserted.

In addition, in a separate assembly line known in the art, the assembly is transported by the control of the system and the robot chuck is operated to assemble the assembly.

The power means 41 received by the system is moved to mediate the member 4 supplied from the straight feeder by rotating the sector gear 44 from the solid line to the dashed line as shown in FIG.

At this time, the power means 41 of the linear feeder rotates the drive shaft 42 so that the pinion 43 interlocks the sector gear 44 and the sector gear 44 interlocks the member carrier 45 integrally formed. Thus, the member transfer member 45 having the member 4 inserted into the member insertion recess 50 moves the member 4 vertically in the diagonal direction.

By this movement, the member 4 is moved perpendicularly to the base 10 at the end of the guide guide 30 so that the member transferred horizontally or diagonally by the guide guide 30 is vertically positioned by the member carrier 45. It will be corrected.

At this time, the robot arm 3 is moved to fix the member with the robot chuck and to move the fixed member 4 to the assembly line to facilitate assembly in the assembly line.

As such, the present invention corrects the posture of the member supplied with the member transfer member 45 by the reciprocating motion of the sector gear 44 in the horizontally aligned member 4 so that the robot chuck is mediated to the robot chuck. The posture member can be fixed and supplied to the assembly line.

The intermediary of the member 4, i.e., when the robot transfers the member, the sector gear 44 is conveyed so that the member carrier 45 integrally with the member carrier returns to its initial position and returns the member 45 of the carrier 45 returned. In the 50, the member 4, which is transferred from the guide guide 30, is inserted again to continue the operation continuously in accordance with the signal of the system, such as electricity.

Although the description of the operation according to the assembly line and the configuration of the sensing sensor is omitted in the present invention, this is a known technique and the sensing function of the sensor may be given in various ways. Since it is to be omitted, and the system of the sensor and the assembly line is omitted by the system of the automation line, the detailed description is omitted, and the driving means can be performed by a motor cylinder or cam type, of course.

As described above, the robot arm is provided with the member 4 in the correct position and in the correct position so that no error occurs in receiving the member 4, and the member 4 is guided without being affected by the vibration of the feeder. By not being pushed or otherwise disturbed by the other members on the guide 30, it can always be supplied to the robot chuck in place to prevent the occurrence of an error.

Therefore, the closed end caused by the supply failure of the member 4 is eliminated as in the prior art. In particular, it is simple to manufacture by adding a correction means composed of a mediation means, posture correction means, and discharge means of a simple configuration to a known feeder. There is an advantage.
