Description

  The present invention relates to a component supply device that detachably attaches to a device main body and supplies chip components by sequentially aligning chip components stored in a loose state in a component storage chamber in a vertical line in a guide path.

This type of component supply apparatus is generally called a bulk feeder, but sometimes a chip component is clogged in the guide passage. In this case, a pressing plate having a shaft portion protruding to the outside is provided on a side surface of a predetermined portion of the guide passage. There is known a technique for protruding and pressing a clogged chip component with this pressing plate to eliminate the clogging (for example, JP-A-8-130392).
JP-A-8-130392

  However, the clogging must be eliminated by pressing the pressure plate with the chip parts clogged in the guide passage. Therefore, it is desirable to prevent the chip parts from clogging.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent as much as possible clogging of chip parts caused by overlapping chip parts.

Therefore, according to the first aspect of the present invention, there is provided a component supply in which the chip components are detachably attached to the apparatus main body, and the chip components stored in the component storage chamber in a state of being separated are aligned in the vertical direction in the guide passage in a row. In the apparatus, the upper part of the passage forming plate is pressed so that the guide passage having a predetermined interval width is formed when the passage forming plate swingably supported and the elastic passage forming plate swings. A first forming member having a pressing plate to be pressed, a second forming member that forms a guide passage for the chip component with the first forming member, and the passage formation so that the chip component is not clogged in the guide passage. And a restricting body for restricting a swing range of the passage forming plate when the plate swings against the pressing plate .

  Further, according to a second invention, in the first invention, when the passage forming plate swings against the pressing body, the restriction of the swing range by the restriction body is one or more and less than two chip parts. It is characterized by being in the range of thickness.

  According to the present invention, the clogging of the chip parts caused by the chip parts overlapping at the entrance of the guide passage can be prevented as much as possible.

  Embodiments of the present invention will be described below with reference to the drawings. First, reference numeral 1 denotes a component supply device called a so-called bulk feeder, and the component supply device 1 includes a storage case 2. A first component storage chamber 4 for storing a large number of loose chip components 3 is formed inside the storage case 2, and an opening formed at the upper end of the first component storage chamber 4 is a lid (not shown). ) And an inclined portion 4 </ b> A inclined forward to such an extent that the chip component 3 can slide down by its own weight is formed on the bottom surface portion of the first component storage chamber 4. Here, the chip component 3 is generally a rectangular parallelepiped electronic component such as a chip capacitor or a resistor.

  A second component storage chamber 5 is formed at a lower front end of the first component storage chamber 4, that is, a funnel-shaped second component storage chamber 5 is communicated with a lower front end of the first component storage chamber 4. An alignment device 6 (described later) communicating with the second component storage chamber 5 is provided below the second component storage chamber 5, and the chip components 3 are sequentially aligned and moved downward. Further, a transfer device 7 (described later) for moving the chip component 3 in the horizontal direction to the component extraction position is connected (provided) to the lower end portion of the alignment device 6.

  Therefore, since a later-described transport belt 60 of the transport device 7 can be shortened as much as possible, the accuracy of the height level of the transport belt 60 can be improved, and the height level can be easily adjusted.

  Here, an automatic chip component mounting device is arranged on the supply side of the chip component 3 of the component supply device 1, and the chip component 3 is adsorbed and taken out from the supply device 1 to the lower part of the mounting device body. A suction nozzle 10 that can be moved up and down to be mounted on a printed board (not shown) is provided. An actuator arm 11 that can move up and down is provided at the lower part of the mounting apparatus body, and the arm 11 moves up and down in synchronization with the operation of the chip component automatic mounting apparatus.

  Below the actuator arm 11, there is provided an operating lever 14 that is urged clockwise by the spring 12 but is restricted by the stopper 13. The operating lever 14 is supported by the lowering of the arm 11. It is swung counterclockwise about 15 as a fulcrum.

  Reference numeral 17 denotes an alignment lever, which is urged to swing counterclockwise by a spring (not shown), but the stopper 13 is locked and the counterclockwise swing is restricted. When the actuating lever 14 swings counterclockwise, it swings counterclockwise around the support shaft 18 as a fulcrum. When the aligning lever 17 swings, the operating member 19 is lowered through a spring (not shown) wound around the lever, and the eccentric member fitted between the two sandwiching pieces on the operating member 19 is fitted. The pins 16 are rotated and raised to operate the alignment device 6.

  As shown in FIGS. 3 to 9, the aligning device 6 is detachably attached to the apparatus main body 1A via respective bolts (not shown) inserted through the upper and lower mounting holes 20 and 20, and is roughly divided into the first. A first forming member 31, a second forming member 32 made of a transparent synthetic resin material and fixed to the first forming member 31 via a bolt, and the first forming member 31 also made of a transparent synthetic resin material. Are formed through a third forming member 36 fixed by bolts 35, and these form an alignment passage 34 in which the chip components 3 are sequentially moved in a line in the vertical direction downward. The alignment device 6 is detachably attached to the apparatus main body 1A via the bolts 30 and 30 if the arrangement device 6 is removed after the storage case 2 is removed. This is because workability is poor.

  In the present embodiment, the second forming member 32 and the third forming member 36 are made of a transparent synthetic resin material. However, any one of the first forming member 31, the second forming member 32, and the third forming member 36 is used. Alternatively, both may be made of a transparent synthetic resin material. In this case, it is necessary to form the part with a transparent material so that at least the part through which the chip component 3 passes can be seen with the naked eye.

  The first forming member 31 includes a flat plate-like main body 37 and three passage forming plates 38, 39, and 40 fixed to the passage forming side of the main body 37 with screws 27 or the like, respectively. A component stirring member 41 is provided at 31. The component agitating member 41 is supported such that one end side is inserted into the opening of the main body 37 via the bearing 42A and the other end side is inserted into the opening 32A of the second forming member 32 via the bearing 42B. A shaft 43, an alignment plate 45 provided at an intermediate portion of the support shaft 43 for sequentially aligning the chip components 3 in the alignment passage 34 by the rotation of the support shaft 43, and an outer peripheral portion (arc portion). A stirring plate 46 having a partially cutout portion 48 and one end side of the support shaft 43 are removably attached to a portion protruding from the main body 37 through the opening of the main body 37 and It is comprised from the rotating plate 47 in which the eccentric pin 16 is provided.

  The alignment plate 45 and the agitation plate 46 attached to the support shaft 43 may be formed integrally with the support shaft 43 or may be detachable.

  The main body 37, the passage forming plate 38, the alignment plate 45 and the stirring plate 46 form an arcuate guide passage 49 communicating with the alignment passage 34. Therefore, the thickness of the alignment plate 45 and the shortest dimension from the outer periphery of the stirring plate 46 to the outer periphery of the alignment plate 45 are formed slightly longer than the dimension of the chip component 3 in the short direction.

  Here, the first forming member 31, the second forming member 32, and the third forming member 36 will be described in detail. First, the opening formed in the passage forming plate 38 is fitted into the pin 26 erected on the main body 37, and the screw insertion of the left screw fitting hole 37 </ b> A and the bolt fitting hole 37 </ b> B opened in the main body 37 and the passage forming plate 39 is inserted. The passage 39 is fixed to the main body 37 with the screw 27 by matching the hole 39C and the bolt insertion hole 39D, and the right screw fitting hole (not shown) and the bolt fitting hole 37C opened in the main body 37. And the screw insertion hole 40A and the bolt insertion hole 40B of the passage forming plate 40 are matched with each other, and the passage forming plate 40 is fixed to the main body 37 with the bolt 25.

  An elastic leaf spring-like pressing plate 28 is fixed to the side wall of the main body 37 by a screw 29 through a screw hole 28A, and a contact forming portion 38C of a passage forming plate 38 that can swing around the pin 26 as a fulcrum. The pressing portion 28B presses and urges the side surface portion of the passage forming plate 38 so as to abut against the restricting portion 39A of the passage forming plate 39 and limit the swinging in the clockwise direction. Therefore, the upper portion of the guide passage 49 having a certain width (thickness of one or more of the chip parts 3 and less than one and close to one thickness) in a state where the swing of the passage forming plate 38 is restricted. However, when the passage forming plate 38 swings counterclockwise against the urging force of the pressing plate 28, the inlet of the guide passage 49 is expanded.

  However, when the passage forming plate 38 swings against the pressing plate 28 so that the two chip components 3 do not overlap and clog in the guide passage 49, the L-shaped shape restricts the swing range. The restricting plate 21 is fixed to the side surface of the second forming member 32 with screws (not shown) with the screw insertion holes 21A and the screw fitting holes (not shown) formed in the second forming member 32 matched.

  Specifically, the upper end portion of the passage forming plate 38 is formed with a protruding portion 38A projecting outward, and the passage forming plate 38 (thin side portion excluding the protruding portion 38A) is formed by the chip component 3 that is overlapped. When the pressing portion 28B of the pressing plate 28 is pressed and rocked against the urging force of the pressing plate 28, the protruding portion 38A comes into contact with the recess forming surface 21B formed on the regulating plate 21, The swing range is regulated. Even when the passage forming plate 38 swings counterclockwise and the entrance of the guide passage 49 expands, the restriction when the passage forming plate 38 swings against the pressing plate 28 is restricted. The regulation of the swing range by the plate 21 is in the range of the thickness of one or more of the chip parts 3 and less than two, so that the chip parts 3 are not clogged even if they overlap at the entrance of the guide passage 49. If there are two or more, two or more chip parts 3 remain clogged at the entrance of the guide passage 49.

  The second forming member 32 is formed with a storage recess 32C for storing the stirring plate 46, and an opening 32A through which the support shaft 43 is inserted through the bearing 42B and an insertion hole 32B of the bolt 33 are opened. The second forming member 32 can be fixed to the first forming member 31 by turning the bolt 33 and inserting the bolt 33 into the bolt insertion hole 32B and then fitting the bolt 33 into the bolt fitting hole 37C via the bolt insertion hole 40B. .

  The third forming member 36 is formed with relief recesses 36A at the heads of the screws 27, and the bolts 35 are turned to pass through the insertion holes 36B and then into the bolt fitting holes 37B via the bolt insertion holes 39D. The third forming member 36 can be fixed to the first forming member 31 by fitting.

  It should be noted that by providing and replacing a plurality of types of passage forming plates 38, 39 and 40 with different thicknesses and sizes, the difference in size of the chip component 3 can be easily accommodated. That is, the guide passage 49 corresponding to the chip component 3 having a different size can be formed.

  On the other hand, a link piece 51 is rotatably connected to the operating lever 14 via a pin 50, and a feed lever 53 connected to the other end side of the link piece 51 via a pin 52 serves as a fulcrum. It is provided so that rotation is possible. Further, the support shaft 54 is provided with a feed claw 55 urged counterclockwise by a spring (not shown) so as to be rotatable, and when the feed lever 53 is rotated clockwise, a feed gear (FIG. When the feed lever 53 returns counterclockwise, the feed gear is rotated and the pulley 56 described later is rotated counterclockwise so that the conveying surface is horizontal. In this configuration, the chip component 3 is transported via the transport belt 60.

  A pulley 56 is provided integrally with the feed gear, and a conveyor belt 60 is stretched between the pulley 56 and pulleys 57 and pulleys 58 and 59 provided at an intermediate portion of the apparatus main body 1A. Passage forming members 61 and 62 are provided for moving the conveyor belt 60 and for moving the chip components 3 that are successively mounted on the belt 60 from the lower end of the alignment device 6. 57, 58, the conveyance belt 60 and the passage forming members 61 and 62 constitute the conveyance device 7.

  On the other hand, one end of the transmission lever 70 engages with a horizontal operation lever (not shown) that moves horizontally in synchronization with the operation of the automatic chip component mounting device, and resists the counterclockwise biasing force of the spring 71. The transmission lever 70 swings clockwise with the support shaft 72 as a fulcrum. During standby, the transmission lever 70 is urged counterclockwise by the urging force of the spring 71, and the contact portion 81 at the other end of the transmission lever 70 The shutter operation is pressed against a contact portion 74 at one end of the component pressing lever 66 integral with the shutter operation lever 73, and is urged to swing clockwise by a spring 76 with the support shaft 75 as a fulcrum. The lever 73 is in a stationary state. That is, the biasing force of the spring 71 is set to be stronger than the biasing force of the spring 76, and the shutter operating lever 73 biased to swing clockwise by the spring 76 swings counterclockwise by the spring 71. Thus, the cam roller 86 presses the upper end portion of the cam surface 84 to restrict the swinging of the shutter operating lever 73 in the clockwise direction.

  The engaging portion 77 at the other end of the shutter operating lever 73 is engaged with the engaging portion 79 at the lower end of the side surface of the shutter 78, which is a non-magnetic material, and the shutter 78 is urged to the right by the spring 80. ing. When the shutter operating lever 73 is locked, the shutter 78 closes the outlet S of the chip component 3. A pair of elongated hole-shaped guide holes 82 are formed on the side surface of the shutter 78, and the guide pins 83 projecting from the side surface of the apparatus main body 1A are fitted to each other so that the shutter 78 can move.

  85 is a component presser that can be swung with a support shaft 67 at the rear end as a fulcrum, and is normally swung counterclockwise with the support shaft 67 as a fulcrum by a spring (not shown) having a lower urging force than the spring 76. The upper part of the component pressing lever 66 is inserted into an opening (not shown) formed on the upper surface of the component pressing member 85, and the component pressing member 85 is rotated clockwise. Normally, the component presser 85 does not press the chip component 3. However, the conveyance of the chip component 3 by the conveyance belt 60 is stopped, the shutter operating lever 73 and the component pressing lever 66 swing counterclockwise, the shutter 78 is opened, and the component pressing 85 is a spring having a weak biasing force as described above. Is rotated counterclockwise, and the next-order chip component 3 is pressed against the conveyor belt 60 from above. The component pressing member 85 is moved clockwise by the movement of the horizontal operation lever (not shown) after the chip component 3 is picked up by the suction nozzle 10 so that the shutter operation lever 73 and the component pressing lever 66 swing clockwise. The pressing of the next order chip component 3 to the conveyor belt 60 is released by the upward movement of the pressing portion.

  In the component supply apparatus 1, an operator holds a lift-up handle 90 and a lock lever 91 disposed at the rear part of the apparatus main body 1A, and the component supply apparatus 1 has a set table (not shown). After positioning by inserting the locating pin 92 into the front and rear positioning holes (not shown), the hook 93 of the lock lever 91 is locked and attached to the locking block (not shown) of the set table. .

  With the above configuration, the operation will be described below. First, as shown in FIGS. 1, 10, and 11, a state where the conveyance of the chip component 3 by the conveyance belt 60 is stopped and the shutter 78 is closed is a standby state. In this standby state, the shutter operating lever 73 urged to swing clockwise by the spring 76 is urged to swing counterclockwise by the spring 71, so that the cam roller 86 is at the upper end of the cam surface 84. In a state where the shutter operating lever 73 is in pressure contact, the clockwise swing of the shutter operating lever 73 is restricted, and the outlet S of the chip component 3 is closed by the shutter 78.

  In this standby state, when the horizontal operating lever moves horizontally in synchronization with the operation of the automatic chip component mounting device, the transmission lever 70 resists the counterclockwise biasing force of the spring 71 as shown in FIG. As the cam roller 86 is guided along the cam surface 84 from the state in which the cam roller 86 is in pressure contact with the upper end of the cam surface 84, the shutter operating lever 73 and the component pressing lever 66 are moved by the spring 76. It swings counterclockwise around the support shaft 75 against the urging force. Then, since the engaging portion 77 at the other end of the shutter operating lever 73 is engaged with the engaging portion 79 at the lower end portion of the side surface of the shutter 78, the shutter 78 resists the urging force of the spring 80 and guide pins 83. Since the shutter 78 moves forward while being guided by the guide hole 82, the outlet S of the chip component 3 is opened.

  At this time, since the component pressing lever 66 also swings counterclockwise, the chip component 3 of the next order is pressed against the conveyor belt 60 from above. Then, in a state where the chip component 3 of the next order is pressed against the conveyor belt 60 from above, the suction nozzle 10 of the automatic chip component mounting device is lowered, and the chip component 3 at the most advanced position (component extraction position) is removed. It is adsorbed and taken out through the opened outlet S.

  In this way, since the next-order chip component 3 is pressed against the conveyor belt 60 from above, the second-order chip component as in the prior art is always held by the component holding pin on the opposite chute wall surface ( Unlike the case of pressing the metal part), it is possible to avoid a situation in which the chip part electrode sticks to the wall surface of the chute and the chip part sticks here and the chip part cannot be conveyed. Further, the conveyance belt 60 is made of rubber and is a soft body, and even when pressed, the chip parts are hardly damaged.

  Then, when the horizontal operation lever moves horizontally rearward, as shown in FIG. 14, the transmission lever 70 rotates counterclockwise by the clockwise biasing force of the spring 71, and the cam roller 86 moves along the cam surface 84. While being guided, it smoothly moves to the upper end of the cam surface 84, and the shutter operating lever 73 and the component pressing lever 66 swing clockwise with the support shaft 75 as a fulcrum by the urging force of the spring 76. Then, since the engaging portion 77 at the other end of the shutter operating lever 73 is engaged with the engaging portion 79 at the lower end portion of the side surface of the shutter 78, the shutter 78 resists the urging force of the spring 80 and guide pins 83. Since the shutter 78 moves backward while being guided by the guide hole 82, the outlet S of the chip component 3 is closed. At this time, the component pressing lever 66 is also swung in the clockwise direction, and the pressing of the next-order chip component 3 to the conveyor belt 60 is released by moving upward of the pressing portion.

  Then, the actuator arm 11 of the automatic chip component mounting device is lowered from the state shown in FIG. 1, and the operating lever 14 is swung counterclockwise about the support shaft 15 as a fulcrum. Accordingly, the feed claw 55 that is already in a position exceeding a predetermined number of teeth of a feed gear (not shown) during standby, the feed lever 53 moves the support shaft 54 via the link piece 51 by the swing of the operation lever 14. Since it rotates counterclockwise as a fulcrum, the feed gear is rotated counterclockwise, the pulley 56 is rotated counterclockwise, and the chip part 3 is conveyed via the conveying belt 60 whose conveying surface is horizontal. (See FIG. 15).

  When the actuator arm 11 is raised, the operating lever 14 is swung clockwise with the support shaft 15 as a fulcrum, and the feed claw 55 moves to a position beyond a predetermined number of teeth of a feed gear (not shown). .

  Further, when the actuator arm 11 is lowered and the operating lever 14 swings counterclockwise with the support shaft 15 as a fulcrum, the operating member 19 is lowered via a spring (not shown) wound around the actuator lever 11. The eccentric pin 16 fitted between the two sandwiching pieces on the upper side of the operating member 19 is rotated and raised to operate the alignment device 6.

  That is, the actuating member 19 is lowered to rotate the eccentric pin 16 and are lowered to return the stirring plate 46 and the alignment plate 45 to the state where the string portion G of the alignment plate 45 is inclined from the horizontal state. The chip components 3 received in the space between the flat plate body 37 and the stirring plate 46 of the first forming member 31 are guided to the alignment passage 34 while being sequentially aligned in a line. At this time, the chip component 3 in the second component storage chamber 5 is agitated by the reciprocating motion of the agitating plate 46 by the lowering and raising of the actuator arm 1, and the main body 37, the passage forming plate 38, the alignment plate 45 and the agitating plate 46 are used. The chip components 3 are guided to the alignment passage 34 while being sequentially aligned through the formed guide passage 49.

  If such a situation is likely to occur so that the chip component 3 is not caught and clogged in the vicinity of the entrance of the guide passage 49 when the stirring plate 46 is swung, the passage forming plate 38 is biased by the pressing plate 28. Against this, the tip part 3 swings a little counterclockwise with the pin 26 as a fulcrum, and the guide passage 49 is expanded. However, even if the passage forming plate 38 swings counterclockwise and the entrance of the guide passage 49 is expanded, the swinging of the passage forming plate 38 is restricted by the restricting plate 21, and the rocking by the restricting plate 21 is also performed. Since the restriction of the moving range is a range of the thickness of one or more of the chip parts 3 and less than two, even if the chip parts 3 overlap at the entrance of the guide passage 49, they are not clogged. Accordingly, the chip component 3 is reliably guided and guided to the alignment passage 34 while being aligned with the guide passage 49 without clogging.

  Therefore, if clogging occurs, the bolts 30 and 30 are removed from the apparatus main body 1A, and the eccentric pin 16 fitted between the two holding pieces on the operation member 19 is removed, and the alignment apparatus is removed from the apparatus main body 1A. After removing 6, it is not necessary to remove the bolts 33 and 35 and remove the second forming member 32 and the third forming member 36 from the first forming member 31 to remove clogging of the chip parts.

  In the above embodiment, the second forming member 32 and the third forming member 36 that constitute the aligning device 6 are configured separately, but may be configured integrally. In other words, the alignment device 6 may be constituted by the first forming member 31 and the second forming member.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various alternatives described above without departing from the spirit of the present invention.
