[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transfer device that inputs a large number of electronic components and the like into a transfer box on which a transfer pattern is formed, and transfers the electronic components and the like to be transferred into the transfer pattern by shaking the transfer box.
[0002]
[Prior art]
Such a transfer apparatus is generally configured to swing a transfer box in one or two axial directions so that the small parts to be transferred placed therein are aligned along the transfer pattern. When the series of transfer operations is completed, the loader moves toward the transfer box, and the parts arranged along the transfer pattern are moved to the loader side. The loader conveys the aligned parts to a standby position of another jig, and moves the aligned parts to the jig as it is. By repeatedly performing this operation, the parts put in the transfer box are aligned in a state along the transfer pattern.
[0003]
[Problems to be solved by the invention]
In order to efficiently perform the transfer operation by the transfer device, it is desirable to swing the transfer box three-dimensionally rather than planarly. Further, in order to efficiently perform the transfer operation, it is desirable to be able to adjust at what period and with what amplitude the transfer box is shaken according to the component to be transferred. Furthermore, it is desirable that after completing a series of transfer operations, the parts arranged in the transfer pattern of the transfer box can be efficiently transferred to a jig or the like waiting at another position.
[0004]
In view of these points, an object of the present invention is to realize a transfer apparatus that can efficiently perform a transfer operation and a transfer operation of components after transfer.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the transfer device of the present invention employs a configuration having a transfer box having a transfer pattern formed on the inner peripheral surface, and a transfer box driving means for giving a combined reciprocating motion to the transfer box. ing. As a transfer box driving means for reciprocating the transfer box, a transfer box installation base for installing the transfer box and a transfer box fixing mechanism for fixing the transfer box installed on the transfer box installation base to the transfer box installation base And a rotation mechanism that swings the transfer box installation base within a certain angle range, and a slide mechanism that linearly reciprocates the transfer box installation base.
[0006]
In the transfer device of the present invention adopting this configuration, when the rotating mechanism and the slide mechanism are driven simultaneously, the transfer box mounting base on which the transfer box is installed moves back and forth linearly in a certain direction while swinging. Do exercise. By such a combined reciprocating motion, the transfer parts put in the transfer box are efficiently transferred into each transfer recess of the transfer pattern.
[0007]
Here, in order to simultaneously drive the transfer box installation table by the rotation mechanism and the slide mechanism, the transfer box may be supported by the rotation mechanism and the rotation mechanism may be supported by the slide mechanism.
[0008]
Next, as a slide mechanism, a slide table, a slide guide that supports the slide table so as to be reciprocally linearly movable, an eccentric roller that rotates eccentrically around a perpendicular perpendicular to the slide table, and the slide table On the other hand, it is possible to employ a configuration that includes a roller receiver that is supported so as to be movable in a direction orthogonal to the moving direction and that contacts the eccentric roller.
[0009]
In the slide mechanism having this configuration, when the eccentric roller is rotated eccentrically, the roller receiver is pushed accordingly, and the slide table to which the roller receiver is attached reciprocates in the direction along the slide guide. In this slide mechanism, if the amount of eccentricity of the eccentric roller can be adjusted, the stroke of the linear reciprocating motion of the slide table can be changed.
[0010]
Next, as a transfer box fixing mechanism, a fixing member that presses and fixes the transfer box against the transfer box installation base, and a spring member that presses the fixing member in a direction along the rotation center line of the rotating mechanism And a fixing release member that pulls the fixing member away from the transfer box against the spring force of the spring member. In this case, the fixing member and the fixing release member may be connected in a state where the fixing member can revolve around the rotation center line of the rotation mechanism.
[0011]
In the transfer box fixing mechanism configured as described above, when the fixing release member attached to the fixed position is operated, the fixing member is pulled away from the transfer box. However, in a state where the fixing release member is not operated, the fixing member pressed against the transfer box can swing around the rotation center line of the rotation mechanism together with the transfer box.
[0012]
Here, the transfer box includes a bowl-shaped box body having a shallow bottom, and a flat cover in which a plurality of transfer recesses constituting the transfer pattern are formed on the inner surface. A configuration in which a taper surface that is pressed against the box body by the pressing force of the fixing member is formed can be employed. According to this configuration, when the fixing member is pressed against the transfer box side and the transfer box is fixed to the transfer box installation base, the fixing force for this acts on the taper surface of the transfer box cover, and the cover is attached to the box body. It also acts as a pressing force to fix to the side.
[0013]
Next, in the transfer device of the present invention, the transfer box is made up of a bowl-shaped box body, a flat lid having a plurality of recesses for transfer forming the transfer pattern on the inner surface, An air suction mechanism that sucks the transfer component transferred to the transfer recess into the recess is provided. Further, a magnet chuck metal fitting made of a magnetic material is attached and fixed to the outer surface of the lid.
[0014]
If the transfer box having this configuration is used, the lid can be used as it is as a conveying jig, and the parts that are transferred and aligned can be transferred as they are to a jig waiting at another position. Further, since the lid may be attracted by using a permanent magnet for the transfer, even if a power failure or the like occurs during operation, the lid does not fall and the aligned parts are not scattered.
[0015]

The transfer box 2 has a flat rectangular parallelepiped shape as a whole, and includes a bowl-shaped box body 21 and a flat lid 22. On the inner surface 22a of the lid 22, a transfer pattern 24 having a configuration in which transfer recesses 23 for transferring parts to be transferred (not shown) are arranged in a matrix, for example, is formed. An adsorption air passage 22b is formed on the back side of the transfer pattern 24, and the bottom of each transfer recess 23 communicates with the adsorption air passage 22b through a communication hole 22c. The adsorption air passage 22 communicates with a flexible air suction tube 25 connected to the side surface of the lid 22 (see FIG. 1B). The air suction tube 25 communicates with an air suction pump (not shown).
[0018]
On the surface side of the lid 22, taper pads 26 a and 26 b that are pressed by the transfer box fixing mechanism 5 are attached to the edges in the short side direction. A pair of disk-shaped magnet chuck fittings 27a and 27b are fixed to the surface of the lid 22 at symmetrical positions. These metal fittings are made of a magnetic material.
[0019]
On the other hand, lid guide pins 28 project vertically from the end surface 21a on the opening side of the box body 21 at a predetermined interval. A pin hole 22 d into which the tip end portion of these guide bins 28 is inserted is formed on the lid 22 side.
[0020]
Next, the transfer box installation stand 4 includes a bottom plate 41 and side plates 42a and 42b that are vertically attached to both sides of the bottom plate 41, and the transfer box 2 is inserted into the recess formed between these side plates from above. Installed. A plurality of transfer box guide pins 43 protrude vertically from the inner bottom surface of the bottom plate 41. On the transfer box 2 side, a plurality of pin holes 21 a into which these transfer box guide pins 42 can be inserted are formed on the bottom plate back surface of the box body 21.
[0021]
(Transfer box fixing mechanism)
FIG. 3 shows a transfer box fixing mechanism 5 for fixing the transfer box 2 to the transfer box installation base 4 side. The transfer box fixing mechanism 5 includes a pair of left and right fixing members 51 arranged to press and fix the transfer box 2 to the transfer box mounting base 4, and these fixing members 51 along the rotation center line 6 a of the rotation mechanism 6. And a fixing release member 53 that pulls the fixing member 51 away from the transfer box 2 against the spring force of the spring member 52.
[0022]
The fixing member 51 on one side includes a fixing claw 51a having a taper surface capable of coming into contact with the taper surface of the stopper 26a disposed at both ends of the lid 22 of the transfer box 2, and the fixing claw 51a. The pulling pin 51b is supported. The pin 51b is supported by the side plate 42a of the transfer box installation base 4 via the pin slide guide 51c in a state in which the pin 51b can move in a direction parallel to the rotation center line 6a. The coil spring which is the spring member 52 is disposed in a compressed state between the back surface of the fixing claw 54 and the pin slide guide 51c, and the pin which supports the fixing claw 51a by the spring force of the spring member 52. 51b is always urged in the protruding direction, that is, the direction in which the transfer box 2 is pressed.
[0023]
The pin 51b protruding from the back side of the pin slide guide 51c has a fixed gap between a large-diameter flange 51d for preventing pin removal and a large-diameter flange 51e for connection to the fixing release member 53 side. Open and formed. The fixing release member 53 includes a connection fitting 54 provided with a groove 54a that can be engaged with the flange 51e of the pin 51b, and a fixing release air cylinder 55 connected to the operating rod 55a on the back side of the connection fitting 54. The air cylinder 55 is fixed to a slide mechanism 7 described later via a bracket.
[0024]
Here, the groove 54a formed in the connection fitting 54 has a cross-sectional shape in which the opening side is constricted and, as shown in FIG. 3B, a circle centering on the rotation center line 6a of the rotation mechanism 6. It is an arcuate groove.
[0025]
The transfer box fixing mechanism 5 on the other side has the same configuration.
[0026]
In the transfer box fixing mechanism 5, when the air cylinder 55 is not operating, that is, in the state shown in FIG. 3, the fixing claws 51 a on both sides are applied to the lid 22 of the transfer box 2 by the spring force of the spring member 52. 26a is pressed. Since both the fixing claw 51a and the stopper metal 26a have tapered surfaces, the transfer box 2 is pressed and clamped by the fixing claw as a whole, and the lid 22 is pressed against the box body 21 side. As a result, the transfer box 2 is fixed to the transfer box installation base 4 side with the lid 22 closed. In this fixed state, when the transfer box 2 swings together with the transfer box installation base 4 around the rotation center line 6a by the rotation mechanism 6 described later, the pin 51b fitted in the groove 54a of the fixed-side coupling metal 54 The portion of the flange 51e is movable along the arc-shaped groove 54a. Therefore, there is no problem in the swing operation of the transfer box 2 even in the fixed state.
[0027]
Next, when the air cylinder 55 is driven to retract the operating rod 55a, the constricted portion of the groove 54a of the connecting fitting 54 at the tip engages with the flange 51e of the pin 51b, and the pin 51b is resisted against the spring force. pull. As a result, the fixing claw 51a is pulled away from the transfer box 2, and the fixed state of the transfer box 2 is released. At the same time, it is free to open the transfer box lid 22.
[0028]
(Rotating mechanism)
The rotation mechanism 6 will be described with reference to FIG. The rotating mechanism 6 has rotating shafts 61a and 61b extending coaxially along the rotation center line 6a from the outer surfaces of the side plates 42a and 42b on both sides of the transfer box installation base 4. The rotary shafts 61a and 61b are supported in a freely rotatable state by a pair of left and right vertical brackets 71a and 71b that constitute a slide mechanism 7 described later. The tip of one rotating shaft 61a protrudes outward through the bracket 71a, and a driven sprocket 62 is fixed to this protruding portion. A drive side sprocket 64 fixed to the tip of the output shaft 63a of the transfer box rotating motor 63 is located immediately below the sprocket 62, and a timing belt 65 is bridged between them. The motor 63 is supported on the side of the later-described slide mechanism 7 via a bracket.
[0029]
When the transfer box rotation motor 63 is driven, the transfer box installation base 4 on which the transfer box 2 is installed can be rotated around the rotation center line 6a. In this example, by driving and controlling the motor 63, the transfer box installation base 4 is swung within a certain angle range.
[0030]
(Slide mechanism)
The slide mechanism 7 will be described with reference to FIGS. 1 and 4. The slide mechanism 7 rotates eccentrically around a slide table 72, a slide guide 73 supporting the slide table 72 so as to be capable of reciprocating linear movement in the direction of the rotation center line 6a, and a perpendicular line 7a orthogonal to the slide table 72. An eccentric roller 74 and a roller receiver 75 supported by the slide table 72 are provided.
[0031]
The roller receiver 75 has a circular inner peripheral surface of a size that allows the eccentric roller 74 to be fitted. Further, the roller receiver 75 passes through the slide guide 76 in a direction orthogonal to the direction of the rotation center line 6a with respect to the back surface of the slide table 72, that is, in a direction orthogonal to the slide direction of the slide table 72. It is supported in a reciprocable state.
[0032]
The eccentric roller 74 is supported by a roller support member 77. The roller support member 77 is connected to the output shaft of the transfer box slide motor 78 and rotates around the perpendicular line 7a. The center of the eccentric roller 74 is located at a position 7b that is eccentric by e with respect to the perpendicular line 7a (motor rotation shaft) by the roller support member 77.
[0033]
When the motor 78 is driven, the eccentric roller 74 supported by the roller support member 77 rotates eccentrically around the perpendicular line 7a by the eccentric amount e. The eccentric roller 74 is in contact with a roller receiver 75 slidable in a direction perpendicular to the slidable direction with respect to the slide table 72. Therefore, when the eccentric roller 74 rotates eccentrically, the slide table 72 performs a reciprocating linear motion in the sliding direction.
[0034]
Here, as can be seen from FIG. 4, the roller support member 77 includes an eccentric piece 77 a that supports the roller shaft 74 a of the eccentric roller 74, and the eccentric piece 77 a is orthogonal to the sliding direction B of the slite table 72. A guide surface 77b supported so as to be movable in the direction A and an eccentricity adjusting bolt 77c capable of adjusting the position of the eccentric piece 77a are provided. If the position of the eccentric piece 77a is moved in the direction of arrow A by the eccentric amount adjusting bolt 77c, the amount of eccentricity of the eccentric roller 74 can be changed. In other words, the stroke of the slide table 72 can be adjusted.
[0035]
(Transfer box lid transport mechanism)
In addition, in FIG. 5, the example of the cover conveyance mechanism suitable for conveying the cover 22 of the transfer box of the transfer apparatus 1 of this example is shown. A pair of magnet holders 82 and 83 extend vertically from the lower surface of the transfer arm 81 of the transfer mechanism 8. Disk-shaped magnets 84 and 85 are fixed to the lower end surfaces of these magnet holders 82 and 83 by adhesion or the like. From the center of each magnet 84, 85, guide pins 86, 87 project vertically downward. Pin holes 29 a and 29 b into which these guide pins 86 and 87 can be inserted are formed at the centers of the magnet chuck fittings 27 a and 27 b of the lid 22. Further, a cylinder 88 for releasing the lid chuck is vertically mounted between the magnets 84 and 85 with respect to the transfer arm 81, and the operating rod 88a can protrude downward. .
[0036]
The transport mechanism 8 having this configuration positions the arm 81 immediately above the lid 22 when the lid 22 is transferred. Then, the arm 81 is lowered and the corresponding magnet chuck fittings 27a and 27b are attracted by the magnetic force by the pair of magnets 84 and 85. As a result, the lid 22 is chucked on the transport arm 81 side as shown in FIG. In order to release the chucking of the lid 22, the cylinder 88 is driven and the lid 22 is pulled downward by the operating rod 88a.
[0037]
(Transfer device operation)
Operation | movement of the transfer apparatus 1 comprised as mentioned above is demonstrated. First, a large number of small parts to be transferred are placed in the transfer box 2 and the lid 22 is put on. Then, the transfer box fixing mechanism 5 is held in the released state, and the transfer box 2 is installed on the transfer box installation base 4. After the transfer box 2 is installed, the transfer box 2 is fixed to the transfer box installation base 4 by the transfer box fixing mechanism 5. FIG. 1 shows this state.
[0038]
Next, the rotation mechanism 6 is driven to reverse the transfer box mounting table 4 to which the transfer box 2 is fixed 180 degrees, and the drive mechanism 6 is temporarily stopped in the inverted state. In this inverted state, the lid 22 is positioned on the lower side, and a large number of small parts are accumulated on the transfer pattern 24 formed on the upper surface. Thereafter, by repeating forward rotation and reverse rotation of the rotation mechanism 6, the transfer box 2 is swung in a certain angle range around the rotation center line 6a.
[0039]
At the same time, the side of the slide mechanism 7 is also driven. When the slide mechanism 7 is driven, the slide table 72 starts a reciprocating linear motion with a constant stroke in a direction B parallel to the rotation center line 6a. The rotation mechanism 6 and the transfer box installation base 4 are supported by the slide mechanism 7. Accordingly, the transfer box installation base 4 on which the transfer box 2 is installed swings around the rotation center line 6a while reciprocating linearly in the direction of arrow B. Accordingly, the transfer box 2 performs a combined reciprocating motion. By giving such a combined reciprocating motion, the small parts put in the transfer box 2 are efficiently transferred to the transfer recess 23 constituting the transfer pattern 24.
[0040]
Here, each of the transfer recesses 23 is sucked to be in a reduced pressure state. Accordingly, the components transferred to the transfer recess 23 are not attracted to the components and are not dropped off.
[0041]
After the composite reciprocating motion is given to the transfer box 2 for a certain period, the rotation mechanism 6 and the slide mechanism 7 are stopped. And the rotation mechanism 6 is driven, the transfer box 2 is reversed 180 degree | times, and it returns to the state shown in FIG. Thereafter, the fixing by the transfer box fixing mechanism 5 is released, and the lid 22 is made removable.
[0042]
In this state, the lid 22 is attracted by a magnetic force using the transfer arm 81 and transferred in a predetermined case. Then, the parts are moved while being aligned with a jig (not shown) waiting in advance. In this operation, for example, it is desirable to use the knock pin to reliably move the components transferred to the transfer recesses 23 to the jig side.
[0043]
Thereafter, the same operation is repeated to perform the transfer operation of the parts put in the transfer box 2.
[0044]
【The invention's effect】
As described above, in the transfer device of the present invention, the transfer operation of parts can be efficiently performed by giving a combined reciprocating motion of swinging in a certain angular range and reciprocating linear movement to the transfer box. Can do.
[0045]
In addition, since the fixing mechanism for fixing the transfer box to the transfer box setting table can be fixed to the transfer box setting table in a swingable state, the transfer box swing mechanism can be realized with a simple configuration.
[0046]
Furthermore, the slide mechanism for sliding the transfer box is configured to change the stroke in the slide direction. Therefore, since the transfer box can be slid with a stroke corresponding to the component to be transferred, an efficient transfer operation can be realized.
[0047]
Furthermore, the lid of the transfer box can be used as it is as a transfer tool for transferring the transferred parts, so the mechanism is simpler and the efficiency is improved compared to the case of using a dedicated transfer tool as in the past. To do.
[0048]
In addition to this, when transferring the lid of the transfer box, the lid is chucked using the magnetic force of the magnet, so there is no chucking force at the time of a power failure like other chucking mechanisms. There is an advantage that there is no possibility of being released.
