BACKGROUND ART Conventionally, in order to change the conveyance direction of conveyed articles, intersecting conveyors are connected by a gutter-like slide.

Problems to be Solved by the Invention However, since the gutter-shaped slide in the above-mentioned prior art is twisted, it is not possible to convey the conveyed articles smoothly and accurately at a constant pitch. Also, it cannot respond to speed increases. There were problems such as the need for a larger space.

SUMMARY OF THE INVENTION Therefore, the present invention provides an apparatus for changing the direction of conveyed articles, which is capable of conveying conveyed articles smoothly and accurately at a constant pitch in a narrow space, and also speeds up the conveyance work. This is what I am trying to do.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to use a receiving plate in which discharge holes for conveyed articles are formed in a direction intersecting the direction in which the conveyed articles fall. A direction changing wheel is rotatably supported and has a plurality of direction changing holes radially formed for storing and changing the direction of a falling conveyed article, and this direction changing wheel is rotated intermittently to change the direction of the conveyed article. The apparatus is equipped with an intermittent drive device that sequentially aligns the direction changing hole with the discharge hole of the receiving plate for discharge.

Effects The effects of the technical means of the present invention are as follows. The intermittent drive device is driven to rotate the direction changing wheel intermittently, thereby changing the direction of the conveyed article that has fallen into the direction changing hole of the direction changing wheel. The conveyed article after the direction change can be discharged from the discharge hole by aligning the direction change hole with the discharge hole of the receiving plate.

EXAMPLE Hereinafter, an example in which the direction changing device of the present invention is used to transport a fixed film resistor (hereinafter simply referred to as a resistor), which is an electronic component with lead wires, in a tape separating device will be described in detail with reference to the drawings. do. First, the outline of the separating tape device will be explained. As shown in FIGS. 1 and 2, in the resistor R, both ends of the lead wire R2 on both sides of the main body R1 are taped with a backing tape T1 and an adhesive tape T2. . This taped resistor R is pulled out from the reel 1 or box 2, passes through the supply guide 3, and the base of the lead wire R2 on the main body R1 side is inserted into the engagement groove 6 of the support wheel 5 supported on the machine frame 4. The inner positions of the tapes T1 and T2 in the lead wire R2 are engaged with the engagement groove 8 of the separating tape wheel 7. The taped resistor R is then conveyed downward as the support wheel 5 and the separating tape wheel 7 rotate. Since the separating tape wheel 7 rotates symmetrically inclined with respect to the support wheel 5, the tapes T1 and T2 are moved side by side by the protrusions 10 whose distance becomes gradually wider while the taped resistor R is conveyed downward. It is pushed toward the side and gradually separates from the lead wire R2, reaches the lower side, and the lead wire R2
completely withdrawn from it. Removed tape T
1 and T2 pass through a discharge roller 11 and a guide 12 and are wound up on a reel (not shown) or fall naturally. On the other hand, the tape-released resistor R is discharged from the lower side of the support wheel 5 and the tape-release wheel 7.

The direction of the resistor R separated by the tape separating device 13 in this manner is changed by the direction changing device 21 of the present invention. Direction changing device 21 of the present invention
will be explained based on FIGS. 1 to 4. As shown in FIGS. 1 and 2, a delivery wheel 22 is provided below the support wheel 5. This delivery wheel 22 has a shaft 23 supported by a bearing 24 provided on the machine frame 4 and a one-way roller clutch 25 for preventing reverse rotation, and a lead wire R2 of a resistor R is connected to protrusions 26 on the outer periphery of both sides. A large number of V-shaped engagement grooves 27 are formed at approximately equal intervals, and a housing groove 28 for housing the main body R1 of the resistor R is formed at the center of the outer periphery. Guide plates 30 are provided on both sides of the delivery wheel 22 on the conveyance side to prevent the lead wire R2 of the resistor R from coming off the engagement groove 27, and these guide plates 30 are connected to the machine frame 4. Fixed. A gear 31 is attached to the side surface of the release tape wheel 7, and this gear 31 meshes with a gear 32 attached on the shaft 23. Therefore, as the supporting wheel 5 and separating tape wheel 7 rotate, the delivery wheel 22 can be rotated via the gears 31 and 32, and the resistor R transferred to the lower part of the supporting wheel 5 and separating tape wheel 7 is The lead wire R2 is guided by the guide plate 30 to the delivery wheel 22.
is passed through the engagement groove 27 of the delivery wheel 22.
It is transferred to the bottom of.

As shown in FIGS. 1 to 4, a receiving plate 33 is attached to the machine frame 4 below the delivery wheel 22, and a direction changing wheel 34 is mounted on this receiving plate 33.
is provided. This direction changing wheel 34
A groove 35 is formed on the outer periphery of the central part of the wheel 3, and this groove 35 is engaged with a bearing 36 rotatably supported at a plurality of locations on the receiving plate 33.
4 can rotate while sliding on the receiving plate 33. A resistor R discharge hole 37 is formed in the receiving plate 33 in a direction intersecting at approximately 90 degrees with the falling direction of the resistor R falling from the lower side of the delivery wheel 22 inside the direction changing wheel 34. ing.
A plurality of direction changing holes 38 (eight in the illustrated example) are formed radially in the direction changing wheel 34 for accommodating the resistor R and changing the direction.
(see figure). A gear 40 is formed on the outer periphery of the upper part of the direction changing wheel 34. As shown in FIGS. 2 to 4, a stay 41 is attached to the machine frame 4, and this stay 41 has a rotary drive source. A solenoid 42 is attached.
A shell type roller clutch 44 for one-way rotation is fitted on the outer periphery of the output shaft 43 of the solenoid 42 to prevent reverse rotation. A drive gear 45 and a constant angle stop wheel 46 are attached to the roller clutch 44 so as to be able to rotate together. Drive gear 4
5 is meshed with the axle 40 of the direction changing wheel 34. The constant angle stop wheel 46 has a direction change hole 38 of the direction change wheel 34 on its outer periphery.
Arc-shaped engaging recesses 47 are formed equally divided into the same number (eight in the illustrated example). The base of a swing arm 48 is swingably supported on the stay 41 by a shaft 50, and an engagement ring 51 made of a bearing is rotatably supported at the tip of the swing arm 48. A tension spring 54 is tensioned between a spring hook 52 erected on the intermediate portion of the swinging arm 48 and a spring hook 53 erected on the stay 41, and the elasticity of the tension spring 54 causes the engagement ring 51 to move at a fixed angle. It is energized so as to engage with the engagement recess 47 of the stop wheel 46. Therefore, the actuation of the solenoid 42 causes the direction changing wheel 3 to move through the roller clutch 44, the drive gear 45 and the axle 40.
4 can be rotated intermittently at predetermined angles (45 degrees in the illustrated example), and at this time, the direction change wheel 34 is rotated at a predetermined angle by engagement of the engagement ring 51 with the engagement recess 47 of the constant angle stop wheel 46. It can be stopped with .

0, they fall sequentially from the engagement groove 27. The dropped resistors R are sequentially accommodated in the direction changing holes 38 of the direction changing wheel 34 which has rotated intermittently by 45 degrees and stopped as described above, and is supported on the receiving plate 33. The resistor R housed in the direction changing hole 38 is connected to the direction changing wheel 3 as described above.
4, it is pushed by the inner wall of the direction changing hole 38 and is intermittently transferred on the receiving plate 33 while changing direction. During this time, the succeeding resistor R is stored in the rear direction changing hole 38, but the main body R1 of this succeeding resistor R is the main body R1 of the resistor R stored in the forward direction changing hole 38. It will be layered on top. When the direction of the resistor R is changed by intermittent rotation of the direction changing wheel 34 in a direction that intersects 90 degrees with the direction at which the resistor R was dropped, the direction changing wheel 3
The direction change hole 38 of No. 4 is the discharge hole 37 of the receiving plate 33.
As a result, the resistor R in the direction changing hole 38 is discharged through the discharge hole 37. The discharged resistor R has its lead wire R2 supported on the guide rail 58, and is attached to the moving conveyance chain 5.
It is engaged by the attachment mench 57 of No. 6 and conveyed.

Thereafter, by repeating the above operation, the resistor R can be sequentially conveyed while changing its direction in a direction perpendicular to the falling direction.

If the resistor R is conveyed by changing its direction in a direction crossing the falling direction, multiple units of the tape separating device 13 and the direction changing supply device 21 can be used as shown in FIGS. Can be arranged in parallel. On the other hand, if the resistor R is conveyed by the conveyance chain 56 or the like in the same falling direction as in the past, as shown in FIGS. Units must be placed in series.
Therefore, according to the embodiment of the present invention, the space can be reduced to 1/2 compared to the conventional method. Further, the tapes T1 and T2 after being separated can be processed so as not to become a hindrance.

Incidentally, if the receiving plate 33, the direction changing wheel 34, the stay 41, etc. are formed into a unit and supported so as to be rotatable in the vertical direction, adjustment work etc. can be easily performed.

Effects of the Invention As is clear from the above description, according to the present invention, a conveyed article is sequentially accommodated in a plurality of direction change holes formed radially in a direction change wheel that rotates intermittently, and the conveyed article is used for direction change. By rotating the wheel, the direction is changed relative to the direction in which it was dropped, and it is discharged from the discharge hole in the receiving plate. Therefore, it is possible to transport articles smoothly and accurately at a constant pitch in a narrow space.
