Description

Rotary object feeder {ROTARY OBJECT FEEDER}

The present invention relates to a rotary object feeder, and more particularly, to a rotary object feeder to suck the object (eg, pad) in the object supply magazine, rotate the object at an angle, and then place it on the conveyor for packaging.

Various rotary object feeders have been known in the art. For example, US Pat. No. 5,910,078 discloses a rotary object feeder that picks up a folded carton from a storage magazine and places it on a conveyor.

This rotary object feeder uses a hypocycloid curve, which is a curve that draws one circumference of a small circle when it rolls along the inside of a large circle without sliding a small circle. It consists of a circle with four sharp vertices.

That is, the rotary object feeder installs a storage magazine at one vertex and a conveyor at another vertex as the suction cup moves along the hypocycloid curve. Then, when the adsorption cup of the rotary object feeder rotates, the adsorption cup reaches the vertex corresponding to the storage magazine, adsorbs and attaches the object, rotates it by an angle, and when it reaches another vertex, separates the object and places it on the conveyor.

As such, the rotary object feeder according to the prior art allows the angular velocity of the adsorption cup to adsorb or separate the object at an apex of the hypocycloid curve close to " 0 ". However, the time when the angular velocity of the adsorption cup approaches "0" at the peak of the hypocycloid curve is very short. Therefore, when the adsorption cup sucks or lowers the object, the rotational force of the adsorption cup extends to the object, so that the objects stacked on the storage magazine are inclined or fallen to one side, thereby preventing the supply of the object smoothly. In addition, when a film or the like is attached to the object, there is a problem that the film is separated or damaged by the rotational force of the suction cup. In addition, the rotary object feeder according to the prior art has a problem in that the structure is complicated and the connection structure of the hose for forming a vacuum in the suction cup is complicated, the overall structure of the device.

As shown, the rotary object feeder 1 according to the present invention, the support plate 2, and the upper rotating plate 12a which are installed in parallel at regular intervals on the rotating shaft 11 is rotatably installed on the support and A disk member 20 including a carrier member 10 including a lower rotating plate 12b, a plurality of disk plates 22 rotatably installed on an upper surface of the upper rotating plate 12a of the carrier member, and A pickup member 30 including a pickup bar 33 rotatably installed on an upper surface of the disk member and a plurality of suction cups 35 installed on one side of the pickup bar 33, and the carrier member 10. Gear member 40 for transmitting the rotational force of the) to the disk member 20 and the plurality of disk plate 22 to rotate, and transmits the rotational force of the carrier member 10 to the pickup bar (33). The pickup bar 33 rotates so that the suction cup 35 always faces outward. Locking cam, which - comprises a gear member (50).

More specifically, the carrier member 10, the rotary shaft 11 rotatably installed on the support (2), and the upper and lower rotary plate 12a (parallel to be installed in parallel at regular intervals on the rotary shaft 11 ( 12b). The upper and lower rotary plates 12 are made of circular plates of the same diameter and rotate together with the rotary shaft 11. And the drive shaft (not shown) is connected to the rotary shaft (11). Accordingly, when the driving motor is operated, the rotating shaft 11 rotates, and when the rotating shaft 11 rotates, the rotating plates 12a and 12b rotate about the rotating shaft 11.

The disk member 20 includes three disk plates 22a, 22b and 22c rotatably installed on the upper surface of the upper rotating plate 12a. The three disk plates 22a, 22b and 22c are made of circular plates of the same diameter and are spaced apart from each other at the same interval. Preferably, the disk plate 22 is composed of a lower disk plate 23 and an upper disk plate 24 to be coupled up and down to form an internal space therein. In addition, the lower surface of the lower disk plate 23 is integrally formed with a hollow shaft 25 extending a predetermined length downward. The hollow shaft 25 extends downward through a through portion formed in the upper rotating plate 12a. Therefore, the disk plate 22 rotates about the upper rotating plate 12a and the rotating shaft 11 and rotates about the hollow shaft 25.

Subsequently, the pickup member 30 includes a pickup bar 33 rotatably installed on an upper surface of the disc plate 22, and a plurality of suction cups 35 protruding from one side of the pickup bar 33. ). The pickup bar 33 is formed of a square rod of a constant length and is provided on a moon shaft 87 to be described later, which is spaced apart from the center of the disk plate 22 by a predetermined distance. And the suction cup 35 is installed to protrude a predetermined length outward from the edge of the rotating plate (12). In addition, a manifold 38 for forming a vacuum in the plurality of suction cups 35 is formed in the pickup bar 33, and a hose 39 is connected to the inlet of the manifold 38. In addition, the hose 39 is connected to a control valve and a vacuum generator (not shown) through the tip of the rotating shaft 11. Thus, when the lunar axis 87 rotates, the pickup bar 33 rotates with the lunar axis 87. When a vacuum is formed in the suction cup 35, an object such as a pad is sucked, and when the vacuum is released, the object is separated from the suction cup 35.

Subsequently, the gear member 40 is installed between the rotating shaft 11 and the hollow shaft 25 to transmit the rotational force of the rotating shaft 11 to the disk plate 22 through the hollow shaft 25, and cut largely. The gear unit 60 and the planet gear unit 70 is included.

First, as shown in FIG. 5, the sun gear part 60 is installed on the rotating shaft 11 and is installed to engage with the sun gear 62 and the sun gear 62 rotating together with the rotating shaft 11. It consists of three lower planetary gears 63. Preferably, the three lower planetary gears 63 are rotatably installed on the upper surface of the cam plate 93 described later. The cam plate 93 is fixed to the support 2 and the rotating shaft 11 penetrates the center thereof. In addition, the three lower planetary gears 63 have the same size and are spaced apart from each other at the same interval. Therefore, when the rotation shaft 11 rotates by the drive motor, the sun gear 62 rotates, and when the sun gear 62 rotates, the three lower planetary gears 63 rotate. At this time, the planetary gear shaft 64 is formed on the upper surface of the lower planetary gear 63 to protrude a predetermined length upward.

6 and 7, the planetary gear unit 80 is installed at the upper end of the planetary gear side 64 and is rotatably installed on the upper surface of the lower rotating plate 12a. ) And three planet gears 75 provided between the lower rotating plate 12a and the upper rotating plate 12a to be engaged with the upper planetary gear 73. The three upper planetary gears 73 have the same size and are spaced apart from each other at the same interval. The planet gear 75 is fixed to the outer circumferential surface of the hollow shaft 25 formed on the lower surface of the disk plate 22. Therefore, when the planetary gear shaft 64 is rotated by the sun gear unit 60, the three upper planetary gears 73 coupled to the upper end rotate, and the upper planetary gear 73 rotates, the upper planetary gear 73 ), Three planet gears 75 engaged with each other rotate. When the planet gear 75 rotates, the three disk plates 22 rotate through the hollow shaft 25. As described above, the gear member 40 including the sun gear portion 60 and the planet gear portion 70 transmits the rotational force of the rotation shaft 11 to the disk plate 22 through the plurality of gears and the hollow shaft 25. Thus, the disk plate 22 is rotated.

Subsequently, as shown in FIG. 8, the cam gear member 50 is provided between the cam plate 93 and the lunar shaft 87 to transmit the rotational force of the rotary shaft 11 to the pickup bar 33. As a large, it consists of the moon gear part 80 and the cam part 90.

First, the moon gear unit 80, the second sun gear 83 is rotatably installed in the center of the disk plate 22, and the moon is rotatably spaced apart from the second sun gear 83 by a predetermined distance It consists of a gear 85 and the idle gear 84 installed so that it may engage between the 2nd sun gear 83 and the moon gear 85. As shown in FIG. At this time, the cam shaft 92 is installed in the middle of the lower surface of the second sun gear 83 extending downward a certain length. The cam shaft 92 extends downward, penetrates the hollow of the hollow shaft 25, penetrates into the rotating plate 12, and extends to the top of the cam plate 93. Accordingly, when the cam shaft 92 rotates, the second sun gear 83 rotates, and when the second sun gear 83 rotates, the moon shaft 87 rotates through the idle gear 84. And when the lunar axis 87 rotates, the pickup bar 33 fixed to the upper end rotates.

Subsequently, the cam part 90 is a disc shaped cam plate 93 fixed to the support 2 and the rotating shaft 11 penetrates the center thereof, and a cam groove 95 formed at a constant depth on the upper surface of the cam plate 93. And a cam block 96 installed at a lower end of the cam shaft 92 and moving along the cam groove 95. The cam block 96 is formed of a rectangular block, and the cam shaft 92 is fixed to one upper surface of the long axis direction, and the roller 97 is rotatably installed on the other lower surface of the long axis direction. The roller 97 is installed to rotate in the state inserted into the cam groove (95). In addition, the cam groove 95 is formed of a closed curve similar to a circle or a circle so as to correspond to the trajectory of the cam shaft 92 rotating about the rotation shaft 11. The roller 97 is rotatably installed while moving along the cam groove 95 in a state of being inserted into the cam groove 95. Accordingly, when the rotating plate 12 rotates, the cam shaft 92 rotates along the circular trajectory along with the rotating plate 12. When the cam shaft 92 rotates, the cam block 96 on which the cam shaft 92 is fixed moves along the cam shaft 92.

On the other hand, the cam block 96 is composed of a rectangular rectangular block, the cam shaft 92 is fixed to one upper surface in the long axis direction, the roller 97 is installed on the other lower surface in the long axis direction. Therefore, when the tip of the cam block 96 rotates along the cam axis 92, the rear end of the cam block 96 moves along the roller 97 inserted into the cam groove 75. That is, when the cam block 96 having a predetermined length moves along a circular trajectory, a rotation force is generated to rotate the rear end toward the outside of the front end of the cam block 96. At this time, the rear end of the cam block 96 is rotatably fixed by the roller 97 and the front end of the cam block 96 is fixed to the cam shaft 92 so that the cam block 96 rotates the cam shaft 92. Let's do it. When the cam shaft 92 rotates, the moon gear portion 80 rotates, and when the moon gear portion 80 rotates, the pickup bar 33 rotates about the moon shaft 87.

As described above, in the rotary object feeder 1 according to the present invention, when the rotating shaft 11 is rotated by the driving motor, the two rotating plates 12 rotate about the rotating shaft 11 and the sun gear unit 60 is rotated. The disk plate 22 rotates through the planet gear unit 70. Moreover, when the rotating plate 12 rotates, the pickup bar 33 rotates by the cam part 90 and the moon gear part 80. Then, since the adsorption cup 35 always faces outward regardless of the rotation of the disk plate 22, the trajectory where the front surface of the adsorption cup 35 moves is in a hypocycloid curve.

Figure 9 shows the trajectory of the rotary object feeder 1 of the present invention, Figure 9a shows an example of a hypocycloid curve having four peaks of the present invention, Figure 9b is the top and bottom of the hypocycloid curve It shows a rotating object feeder (1) equipped with an object supply magazine and a conveyor at the apex of. As shown in FIG. 9A, the rotary object feeder 1 of the present invention draws a hypocycloid curve with four pointed vertices A, B, C, and D. At the sharp peaks A, B, C, and D of the hypocycloid curve, the adsorption cup 35 has an angular velocity of "0".

Therefore, as shown in Figure 9b, the suction cup 35 is provided with an object supply magazine (5) in which a plurality of objects (3) are stacked up and down on the top of the top end (A) angular velocity is "0", The conveyor 7 can be provided in the lower part of the lowest apex (C). In addition, a stacker for stacking the object 3 up and down may be further installed on the conveyor 7. Then, the front surface of the adsorption cup 35 provided on the three disk plates 22 adsorbs the object 3 from the object supply magazine 5 when it reaches the top vertex A while rotating along the trajectory of the hypocycloid curve. After rotating at an angle to reach the lowest vertex C, the object 3 is separated and placed on the conveyor 7. That is, since the angular velocity of the adsorption cup 35 becomes 0 at the sharp vertices A, B, C, and D of the hypocycloid curve, the front surface of the adsorption cup 35 is horizontal with the object 3. The object supply magazine 5 and the conveyor 7 are installed at the uppermost and lowermost vertices A and C.

10 shows the trajectory of the suction cup 35 according to the shape of the cam groove 75 formed in the rotary object feeder 1 of the present invention. FIG. 10A illustrates a case in which the cam groove 75 has a circular shape corresponding to the trajectory O of the cam shaft 92, and FIG. 10B illustrates a case in which the cam groove 75 has an elliptical shape. As shown in FIG. 9A, the rotary object feeder 1 having a cam groove 75 made of a circle draws a hypocycloid curve having four vertices A, B, C, and D, but the adsorption cup 35 at the vertex. The time that the angular velocity of) approaches zero is very short. That is, since the time between the front of the adsorption cup 35 and the object 3 is short, the rotational force is generated before the adsorption cup 35 sufficiently adsorbs or separates the object 3, thereby stably adsorbing or separating the object. Difficult to do In particular, when the rotational force of the suction cup 35 affects the object 3 stacked in the magazine 5, the object stacked on the magazine 5 may be inclined or collapsed to one side so that the object 3 may not be smoothly supplied. May occur.

In order to solve this problem, the present invention provides a sufficient time for the angular velocity of the suction cup 35 to become "0" at the top and bottom vertices (A) and (C) of the hypocycloid curve drawn by the rotary object feeder 1. It extends so that the object 3 can be transported stably. To this end, as shown in Figure 10b, the cam groove 75 according to the present invention is made of an oval having the cam groove 75 has a long axis (a-a ') and a short axis (b-b'). That is, the cam groove 75 includes a portion having a radius of curvature larger than the radius of curvature of the trajectory O of the cam shaft 92 circularly moving around the rotation shaft 11 and a portion having a small radius of curvature. It is made of oval. In addition, a portion of the cam groove 75 further includes an inwardly curved portion 99 that is bent inwardly. In addition, the major axis direction (a-a ') of the elliptical cam groove 75 is installed to be inclined at a predetermined angle between the vertices (B) (C) and (A) (D). In addition, the inwardly curved portion 99 is formed at a radius of curvature larger than the radius of curvature of the trajectory O of the cam axis 92. Preferably, the inwardly curved portion 99 is formed near the vertices A and C at the top and bottom of the hypocycloid curve.

As such, when the shape of the cam groove 75 is changed to an ellipse, when the cam block 36 rotates according to the rotation of the cam shaft 92, the cam groove 75 at the stage before reaching the uppermost vertex A is obtained. Since the radius of curvature of the c) decreases, the cam block 96 rotates rapidly. When the cam block 96 rotates, the cam shaft 92 rotates the pickup bar 33 through the moon gear unit 80. Then, the suction cup 35 formed on one side of the pickup bar 33 is also rapidly rotated to be horizontal with the front surface of the suction cup 35 and the object 3. Then, while the cam block 36 reaches the top vertex A and passes through the inwardly curved portion 99, the cam shaft 92 is hardly rotated because the cam block 96 is horizontal. That is, while the suction cup 35 passes through the inwardly curved portion 99, it is kept horizontal with the object 3. When the cam block 36 passes through the inwardly curved portion 99, the radius of curvature of the cam groove 95 decreases again, so that the cam block 96 rapidly rotates again so that the suction cup 35 rapidly increases the angular velocity. Make sure you recover.

Thus, the rotary object feeder 1 having the elliptical cam groove 75 extends the time at which the angular velocity of the suction cup 35 becomes "0" at the top and bottom apex (C). In other words, the length of the straight portion appearing at the uppermost and lowermost vertices A and C increases by " L ". At this time, the straight portion means the time when the angular velocity of the suction cup 35 becomes "0" so that the front surface of the suction cup 35 and the object 3 are horizontal, so the longer the length of the straight portion, the suction cup 35 becomes the object ( 3) has the effect of stably adsorbing or separating.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention may be modified in various ways, and may have various embodiments. It is not intended to be limited to the form, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.
