Next, the mechanism of the workpiece holding device 'g43, which is an embodiment of the present invention that can be used in the workpiece conveyance device described in "1-2", will be described in detail. As shown in FIGS. 5 and 6, the soak holding device 43 is attached to the tip of a cantilevered arm 46, which is a component of the main body 42 of the conveying device. Pressure or hydraulic cylinder 47
The main components include a work suction section 48 which is moved up and down by the cylinder 47, and the like.

That is, a cylinder 47 is vertically fixed to the tip 1 of the arm 46, and the cylinder 47 is extended and retracted.
A plate 50, which is an example of a τ1 unit, is fixed horizontally to −1 and α1! It has a fixed horizontal rod 52 nearby,
An electromagnet 53 constituting a work holding means, which is a main component of the work suction device 48, is attached to each lot 52 so as to be movable 174 times in the axial direction of the lot 52.

54 is a set bolt for fixing the electromagnet 53 to 1-52, and each time you loosen this bolt, the position of the electromagnet 53 is set to GL! It can be arranged. Note that the direction of the first groove 52 is set to be parallel to the running direction of the first general feeding device main body, that is, the axial direction of the guide rail 41.

The electromagnet 53 described above is a preferable holding means when the workpiece W is made of a magnetic material such as iron, but when the workpiece W is made of a non-magnetic material such as a plastic resin or a ceramic product, an air It is desirable to employ a holding means by suction or a mechanical holding means in which a mechanical claw or the like is operated by a solenoid or a cylinder.

Also, a bracket 55 fixed to the lower surface of the plate 50

The pneumatic cylinder 56 and the like constitute an example of a spacer gripping device. However, the pneumatic cylinder 56 is a solenoid, motor, etc.
It can be replaced with other driving sources.

In addition, symmetrically with the cylinder 47 sandwiched between the plate 50,
Two vertically fixed guide rods 62 are slidably mounted on bearings 63 provided on the arm 1846, and their upper ends are connected by a connecting plate 64. However, a slit 65 is formed on the connecting plate 64 to prevent interference with the cylinder 47, and the connecting plate 64 is prevented from interfering with the hydraulic cylinder 47 due to the expansion and contraction movement of the guide 1'J side 62. ing.

grasp. When the holding of the spacer S and the workpiece W is completed in this way, the cylinder 47 is retracted and the workpiece W is lifted together with the spacer S.

Furthermore, when the conveyance device main body 42 comes over a work discharge part such as a positioning table, until the work W contacts or approaches the positioning table (this position is set aside for the rod 52 etc. The cylinder 47 (detected by a limit switch, etc.) is extended to lower the workpiece W and the spacer S, and when the workpiece W contacts or approaches a positioning table, etc., the attraction force of the electromagnet 53 is released, and then the spacer S is The cylinder 47 is pulled in while being gripped to raise the entire soak holding plate 48, and the entire work holding device 43 is returned to its original position by driving the chain 44. 1F at the designated location on this return route! , each time the pneumatic cylinder 56 is extended, the gripping brake 1/58 is opened and the spacer S is dumped into a predetermined reservoir.

It is preferable that the electromagnet 53 used to attract the work be of a type that releases its attraction force when energized, in order to prevent the work from falling during a power outage.

Next, the mechanism for transporting the workpiece holding device ξ43 as described above will be explained.
As shown in FIGS. 3 and 8, the chain 44 includes a drive line 11 directly driven by a drive line SP1 and a starting point side sprocket SP2.
．． The hook is endlessly passed to the end point side sprocket SP3 and the tension adjustment sprocket SP4, and is driven back and forth by rotating the motor M in the forward and reverse directions.

Such a chain 44 has a shape shown in FIG. 10 or 11 in its middle part.
As shown in the figure, it has a vertical guide roller 45 made of a bearing or the like so as to be rotatable, and as described above, the conveyor main body 42 moves according to the running of the chain 44 due to interference with this guide roller 45. do. That is, the guide rail 41 provided on the frame 40 and the swingable sliding block 66 are fixed to the rear end of the actuator 46, so that the entire transport device main body 42 represented by the arm 46 can be slid on the guide rail 41. Usually, a ball 67 is installed between an axial groove bored in the side surface of the guide rail 4I and an axial groove bored in the inner surface of the sliding block 66 facing the guide rail 4I. With this ball 67”-
The narrowing device main body 42 is designed to eliminate the play between the guide rail 41 and the guide rail 41 due to interference with the respective grooves, and prevent accurate guiding function. As shown in the figure, the guide rail 41 and the guide block 6G interfere with each other at one end to support the C frame 4o in a cantilevered manner. It is necessary to prevent the device main body 42 from tilting.

This is not shown in Fig. 7 and is in line with the purpose of the pressure roller 68, which is attached to the booklet 69 attached to the lower surface of the arm 4G. A nut 71 screwed into the middle of the threaded rod 70 is used to horizontally hold the pressure roller 68 at the tip θj; A compression spring 72 is tightened between the block 69, and the force of this compression spring presses the threaded rod 7 and the pressure roller 68 integrally attached thereto against the side surface 40 of the frame 40. The elastic force of 72 lifts the conveying device main body 42 and prevents it from being lifted slightly.

Furthermore, as shown in FIG. 7, a pneumatic cylinder 74 installed horizontally on the side surface of the channel section 10A'13 to which the arm 46 is connected is used to stop the conveyor main body 42 at a strictly defined position. The telescopic rod 75, which has a positioning function, has a horizontal roller 76 rotatably at its tip. Further, a positioning block 78 in which a vertical V-groove 77 is carved is attached to the side surface of the frame 40 at the correct stop position of the conveyor main body 42.

Therefore, when the conveyance device main body 42 reaches the approximate stop position, the pneumatic cylinder 74 operates simultaneously with or slightly delayed from the stop of the motor M, and the roller 76 protrudes toward the positioning block 78 and engages with the Vtl 77. , ■Groove 7
7, the ill feeder main body 42 is accurately positioned at the center of the V-groove 77. Note that the positioning holder 8o has a telescopic rod 75 to hold the roller 76.
A guide hole 8oa of the holder 79 attached to the tip of the roller 76 is horizontally carved to prevent the roller 76 from wobbling in the horizontal direction.

As is clear from FIG. 8, the two sliding blocks 66 are arranged side by side in the axial direction of the guide rail 41, and both sliding blocks 6G are located at the rear of the arm 4G at the α11.1 section 4 (
They are fixed to the bottom surface of iR at regular intervals. I-
A guide block 82 having two parallel vertical guide holes 81 is fixed to the upper surface of the rear end portion 468, and a guide block 82 is slidably inserted into the guide holes 81 and 81. -1 end portions of 83 and 83 are connected by a connecting plate 84. Also, the end portion 84 of the connecting plate 84
Tension springs 86, 86 are attached between □ and the port 85 installed on the side of the guide rod 82, respectively, so that the guide rod 83, 83 is attached downwardly. Forced. The stopper 87 is a stopper fixed to the connecting plate 84, and is located below the stopper. Ii+, l
Each time the guide block 82 comes into contact with the upper surface of the guide block 82, further downward movement of the throat 83 is prevented.

-J- The lower ends of the two guide rods 83 have a seventh l'
, 1.1, a guide member 89 having a three-pronged portion 88,88 is fixed, and the two-pronged portion 88 of ``1.
-+qi grooves open downward at the lower ends of each
A long groove 90 (see FIG. 8) is formed, and this long groove 9
The width of the guide rail 41 in the longitudinal direction is approximately equal to the outer diameter of the guide roller 45, and is set to such a width that the guide roller 45 can be fitted therein.

The guide member 89 further has a vertical support roller 91 rotatably provided on its side surface on the frame 4o side. This support roller 91 is guided by a guide portion j! by the tension spring 86. This is to counter the downward force acting on A89, for example, as shown in Fig. 8, the sprocket S on the end point side
When P3 is rotated to cause the chain 44 to travel in the direction of arrow 92, the guide roller 45 also moves as part of the chain 44, and this guide roller 45
The support roller 91 moves along the trajectory 93, and the guide roller 45 moves upward along the guide rod 83 and moves in the direction of the arrow 92. Before starting to move away from L SF3 and along the straight section 97 of the chain 44, the support roller 91 rides over the upper surface 40 of the frame 40, and thus the support roller 91 is moved downwardly by the guide member 89 by the tension spring 86. This is to support all of the forces and prevent such inconvenience as the chain 44 sagging downward at its straight portion 97.

” Support 1: J-La 9■ as shown in 1 of the frame 40
- In order to run along the length ζ on the first surface 40b, the support roller 9
Since the movement trajectory of frame 1 must not interfere with frame 40,
Frame 400) A notch 94 as shown in FIGS. 7 and 8 is carved in the vehicle surface 40, and the supports 11-91 can be smoothly aligned.
It is desirable that the end of the notch 94 be formed into a slope 95 so that it can be transferred to d'Ob.

Note that the center line of the guide 45 shown in FIG. 10 is the center line 44 of the chain 44. In the case shown in FIG. 11, the center line of the guide roller 45 coincides with the center line 44. of the chain 44. This shows a type of guide I:1-ra which is eccentric from.

The moving operation of the general feeding device main body 42 is as follows.

First, a description will be given of the state in which the conveying device main body 42 is located at the end point position shown in FIG. In this state, the chain 44 is already running in the opposite direction to the arrow 92, and the guide roller 45 is at the position where it is out of the long groove 90 (i.e., at the position indicated by the solid line 45).
Since the long groove 90 and the guide roller 45 have been released from the engagement with the guide roller 45, the TA feeding device main body 42 is released from the constraint caused by the engagement with the guide roller 45 and is instead moved to the position shown in FIG. Due to the action of the pneumatic cylinder 74 shown in FIG. Once in place, it cannot move in any direction.

In this state that the conveyor main body 42 is accurately positioned and fixed at the end position, the cylinder 47 is moved as described above.
The stretching operation and the releasing operation of the electromagnet 53 are performed, and the workpiece WM is transferred to a predetermined position for the next process, such as the center of the positioning table. Thereafter, the retraction operation of the cylinder 47 is performed again, and the work suction part 48 rises while holding the separator S, and the soak suction part 48 reaches the first part position not shown in FIGS. 5 and 6. At this point, the movement of the hydraulic cylinder 47 stops.

Then, the motor M shown in the figure is driven, and the chain 44 starts running in the direction not shown by the arrow 92. At the same time, the pneumatic cylinder 74 is activated and the roller 76 is moved to V liM 7
7, and the restraint of the first general feeding device main body 42 in the running direction is released.

As the chain 44 moves in the direction of arrow 92, the guide roller 45 moves from the 45' position to the sprocket l' S P

It will go into the long groove 90, and the guide l:I-
Regarding the movement of La 45, the guide part month 839 or slightly arrow 9
Pushed in the direction of 2, guide part 89 and Kaidororad 83
．． The entire first general feeding device main body 42 connected via the guide block 82 and the like moves slightly in the direction of the arrow 92. Eventually, the guide roller 45 comes into contact with the tenth end 90.1 of the long groove 90, but the guide roller 45 further contacts the sprocket SP3.
As the guide member 89 moves along the arc-shaped portion 96 of
f) With the movement of the guide block 89, the main body 42 of the conveying device moves in the direction of the arrow 92.

The moving speed of the conveyor main body 42 at this time is the guide roller 4
5, the speed is 0 when the guide roller 45 starts engaging with the long groove 90, and then the speed is gradually increased, and the guide roller 45 moves toward the chain 44. After reaching the straight line portion, it moves at a constant speed at that speed, and the acceleration acting on the 1M feeding device main body 42 at the time of starting is small, and a starting state with less shock can be obtained. Such a loose (Φ
The i action occurs when the chain 44 runs in the direction opposite to the arrow 92 and the 1ift feeding device main body 42 stops at the end position, and when the chain 44 runs in the direction of the arrow 92 and the transport device main body 42 stops at the starting point. It is exerted when the vehicle reaches the end point and stops, and furthermore, when the vehicle starts again from the starting point toward the end point.

As described above, the guide roller 45 is connected to the sprocket I.S.
While passing through the P 30 circular elastic portion 96, the supporting member 1-ra 91 moves along 1iii. - Straight section 9 of turn 44
7, the support CI-ra 91 rolls along the rim 40b of the frame 40 to be moved to the 1-40b-1-. Therefore, the downward force of the tension spring 8G is constantly applied to the guide member 89 via the guide roller 83, and this force is applied to the guide member 89.
+: You will be pushing the l-ra 45 downward, but the support I
': From the point where the I-ra 91 is transferred to the - of the frame 40 on one side 40, the downward biasing force described in 1- is mostly caused by this support roller 91 i'1ilT,I, No harmful force acts on the guide I:1-ra 45 while it is moving on the straight section 97 and would cause the chain 44 to bend downward.

In this way, while the downward force exerted by the tension spring 86 is absorbed by the support 111-ra 1) 1, the traveling device main body 42 moves in the direction of the arrow +- (+ 2). By activating the pneumatic cylinder 56 to open the grip plate 58, the spacer S is released and allowed to fall into a storage section or the like below.

When the conveyor main body 42 reaches the starting point on the opposite side, the operation is completely opposite to the starting state at the ending point, and the guide roller 45 moves along the pinch arc of the sprocket SP2 on the starting point side shown in FIG. However, when the guide roller 45 finally comes out of the long groove 90, the +a feeding device main body 42 stops, and the pneumatic cylinder 74 acts again to position the guide roller 45 at a predetermined position on the starting point side. The roller 76 is inserted into the groove (not shown) of the block, and the first general feeding device main body 42 is accurately positioned at the starting position. The spacer S placed on top of the spacer S is IM-fed by the action of the workpiece holding device 43 toward the end point of the pick-up 11.

As described above, the present invention is a work holding device for use in a tool 21M transport device that takes out Ill^I τ soaks from a group of loaded works and transfers them.
The apparatus is characterized by comprising a vertical actuator attached to the main body of the work transfer device, a mounting base that is driven by the above-mentioned ゛r displacement device so as to be freely raised and lowered, and a workpiece holding means fixed below the above-mentioned mounting base. Because it is a work holding device, it can accurately hold and transport workpieces of any shape, and when used with a spacer gripping device that grips spacers to partition loaded workpieces, it can be used with a spacer gripping device that grips spacers to partition loaded workpieces. Even when a horizontal suction surface cannot be obtained when loading a workpiece, a spacer can be used to hold the workpiece in a horizontal state and increase the suction of the workpiece to 6 (F). It is possible to reduce malfunctions when holding and emptying.In addition, the spacer prevents collisions between workpieces when they fall into the loaded state, and has the effect of not damaging the workpieces. It can be transported and processed, making a significant contribution to streamlining assembly lines, etc.
