Abstract

PURPOSE:To make undone parts from occurring, by taking out the parts at a time when the undone parts are detected in time of chuck return motion by an undone parts detecting sensor installed in the chuck. CONSTITUTION:A chuck 29 moves up to a parts housing column 2b at the second column of a parts housing box 1 from a rectilinear feeder 43. And, when it passes through a parts housing column 2a at the first column, in the case where one unit or plural units of parts 3a are left behind in the column 2a, space between sensors 34 and 34 of the chuck 29 is shaded from light by the parts 3a, whereby these sensors 34 and 34 detect these undone parts 3a, inputting their detection signals into a control circuit, thus a driving motor comes to a stop. Therefore, the chuck 29 is opposed to the parts housing column 2a at the first column and stops, while upper and lower cylinders operate, making the chuck 29 go down, and the parts 3a are taken out upon chucking by a chuck piece and fed to the rectilinear 43. Thus, a speed-up for taking out these parts is achievable and, what is more, there are no undone parts behind and all parts can be taken out without fail.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for simultaneously taking out a plurality of parts from a parts storage box containing, for example, electrical parts and mechanical parts.

[Technical background of the invention and its problems]

On an engine assembly line, when supplying engine parts, such as spark plugs, to the assembly line, first, a large number of ignition bladders or parts stored in a parts storage box are taken out by a chuck and fed to a linear feeder. . In this case, it is necessary to quickly feed the parts to the linear feeder to follow the speed of the assembly line, and to take out and feed the parts one by one from the parts storage box requires speeding up the removal, which cannot be accommodated. There are cases.

Therefore, attempts have been made to simultaneously chuck and take out each row of multiple parts stored in a parts storage box and feed them to a linear feeder at the same time. Therefore, as the number of times it is used increases, it deteriorates and the parts holding position becomes uneven. In other words, the amount of protrusion of the parts from the top surface of the parts storage box may be reduced or the parts may be tilted. Nevertheless, since the chuck is lightweight and simple (preferably in an L configuration, it is composed of a pair of chuck pieces that clamp the parts row from both sides, parts may be left behind. Therefore, each part in the parts storage box There is an inconvenience that even if the parts from one end of the row to the other end are taken out, one or more parts remain in the parts storage box.

[Purpose of the invention]

This invention has been developed by paying attention to the above-mentioned circumstances, and its purpose is to take out a large number of parts stored in a parts storage box for each part row, and to prevent parts from being left behind. The purpose of this invention is to provide a method for simultaneously taking out a plurality of parts, which can reliably take out even the leftover parts.

[Summary of the invention]

In order to achieve the above object, the present invention includes a sensor that detects the presence or absence of parts left behind in the parts storage row on a chuck that reciprocates between the parts removal stage where the parts storage box is installed and the linear feeder that receives the parts. When the presence of a component left behind in the component storage row is detected during the return movement of the chuck, the component is taken out by the chuck, thereby preventing the component from being left behind.

First, when the elevating plate 7 of the elevator stocker 4 is at the upper limit position and the parts storage boxes 1... containing parts 3... are placed in each column 8... One shelf 8 is located at the same level as the parts removal stage 5. In this state, when the air cylinder 22 of the traverser mechanism 16 is operated, the clamp arms 21 and 21ii move toward each other and clamp the parts storage box It on the shelf 8.

Next, when the cylinder 17 is actuated and the slide rod 18 retreats, the flang mechanism 19 slides the parts storage box 1 in the direction of the parts removal stage 5 while keeping it pressed, and places it on the parts storage box 1tA' let 15. . Here, the Franz machine 19 is once opened and moved away from 51 into the parts storage 8', and then closed again to restrain the parts storage box 1, thereby fixing the parts storage box 1 in a predetermined position. On the other hand, the carriage 29 is supported by the moving part 26 and is capable of reciprocating in a direction perpendicular to the component storage rows 2h2b...2g of the component storage box 1, and is driven by a control signal set in advance. When the motor 25 is operated, the chariot 29 is opposed to the component storage row 2aVC. Then, the chuck 29 is lowered to a predetermined position by the upper and lower cylinders 27, and the parts storage row 2a is
Chuck pieces 3θ are placed on both sides of the row parts 3 accommodated in the
When the parts 30 face each other, the chuck pieces 30 and 30 close and the row parts 3 are simultaneously clamped.

When chucking of the parts 3... is completed, the chuck 29 is raised by the upper and lower cylinders 27, and the parts 3 are
... are taken out from the parts storage box 1 at the same time. Next, when the screw rod 23 rotates due to normal rotation of the drive motor 25, the moving member 26 moves forward, and stops when the chuck 29 faces the linear feeder 43. Then, when the chuck 29 is lowered by the upper cylinder 27 and the parts 3 are inserted into the linear feeder 35, the chuck piece 3θ.

When the parts 30 are opened, the plurality of parts 3... are simultaneously transferred to the linear feeder 43.

When the transfer of the components 3 . When the chuck 29 faces the next row, that is, the second component storage row 2b, the same operation as described above is repeated to move the component storage row 2b to the next row.
Chuck and take out part 3 inside. but,
The chuck 29 is transferred from the linear feeder 43 to the component storage box 1
While moving to the second component storage row 2b, it passes over the first component storage row 2a.

At this time, if one or more components 3a are left behind in the first component storage row 2a, the chuck 2
The part 3a blocks light between the sensors 34 and 34 provided in the sensor 9. That is, the sensors 34'', 34 detect the left-behind part 3a and input the detection signal to the control circuit 44 to stop the drive motor 25. Therefore, the chuck 2
9 stops facing the first component storage row 2a, and then the upper and lower cylinders 27 operate to lower the chuck 29. Then, in the same manner as described above, the component 3a is chucked and taken out by the chuck pieces 30 and 30, and is fed to the linear feeder 43.

In this way, the component storage box 10 component storage row 2a2b...
・The parts 3... stored in the parts storage box 1 can be taken out row by row, and the parts 3a left behind can be taken out by the second chucking and fed to the linear feeder 43. Nothing is left behind and everything can be taken out. When the removal of the parts 3 from the parts storage box 1 is completed, the cylinder 17 of the driver mechanism 16 is operated and the slide rod 18 is moved forward. Therefore, the empty parts storage box IFi pallet 15, which had been clamped by the clamp mechanism 19, is returned to the lowest shelf 8. Then, after the clamp mechanism 19 is released, the endless chain 11 is run by the drive motor 1o, and the elevating plate 7 is lowered one pitch, so that the second shelf 8 from the bottom is at the same level as the component removal stage 5. Therefore, by carrying the parts storage box l containing the parts 3 on the shelf 8 onto the pallet 15 by the traverser mechanism 16 in the same manner as described above, it is possible to repeat the removal of the parts 3. .

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to take out a large number of parts stored in the parts storage Wakkanai in each part row, and it is possible to speed up the part taking out, and also to use the chuck for taking out.
