[0031]
The chip component replenishment operation will be described below.
[0032]
With the supply stand 7 stopped at a predetermined position and the component supply device 8 attached to the supply stand 7, as shown in FIG. 5 and FIG. 46 is held with one hand, and the pressed portion 53, which is the exposed upper surface of the lock member 48, is pressed downward against the upward biasing force of the coil spring 58 at one lower end (left lower end in FIG. 5) of the replenishment case 46. As a result of the sliding, the convex portion 52 comes off the concave portion 43 of the upper lid 40, and the upper lid 40 can be unlocked by the convex portion 52 as shown in FIG. In this way, the lock is released, and further, when the protrusion 59 on the side wall is guided by the cutout 50A and the lock member 48 is slightly slid downward, the lower end of the replenishment case 46 is formed at the corner of the storage case 20. Further sliding of the replenishment case 46 and the lock member 48 is restricted by hitting the lower edge of the notch 50.
[0033]
As described above, the lock is released, and the lower end of the replenishment case 46 is in contact with the pressed portion 53 of the lock member 48 and the lower edge of the cutout 50 of the storage case 20 as shown in FIG. Since the protrusion 47 of the replenishment case 46 corresponds to the guide portion 45 of the storage case 20, the operator does not need to perform troublesome alignment between the storage case 20 and the replenishment case 46, as shown in FIG. As described above, the replenishment case 46 can be moved horizontally along the guide portion 45 in a state where the protrusion 47 of the replenishment case 46 and the guide portion 45 of the storage case 20 coincide with each other. Therefore, as shown in FIG. 7, when the top cover 40 is moved in the horizontal direction (left direction in FIG. 7) by the replenishment case 46, the tip of the top cover 40 (left side in FIG. 8) is the edge of the guide portion 45. The upper lid 40 and the replenishment case 46 can no longer move, and the opening 38 of the storage case 20 and the opening of the replenishment case 46 coincide at this position as shown in FIG. Further, as shown in FIGS. 8 and 15, the lock member 48 is moved upward by the bias of the coil spring 58 and the protrusion 56 is located beside the replenishment case 46 (on the right side in FIG. 8). 46 The rightward slide is restricted by the lock member 48. Then, by opening the shutter of the opening of the replenishment case 46 and communicating the outlet with the opening of the storage case 20, the chip components stored in the replenishment case 46 are poured into the storage case 20 without leaking outside. .
[0034]
Next, when the replenishment case 46 is removed from the storage case 20, as shown in FIG. 9, for example, the pressed portion 53 of the lock member 48 is pushed down by hand to slide the lock member 48 downward, and the protrusion 56 is refilled. The lock member 48 is removed from the side of the replenishment case 46 (right side in FIG. 9) to make it free. In this state, as shown in FIG. 10, by sliding the replenishment case 46 in the opposite direction (rightward in FIG. 10), the opening part is detached from the guide part 45, and as shown in FIG. The replenishment case 46 is removed. Further, when the lock member 48 is manually slid downward as described above, when the lock member 48 is further pressed downward after the side of the refill case 46 becomes free, The upper edge abuts on the support member 55, and the downward sliding of the lock member 48 is restricted, so that excessive reduction of the coil spring 58 can be avoided, and malfunction (deformation malfunction) can be avoided.
[0035]
When the replenishment case 46 is removed, the lock member 48 slides upward by the biasing force of the coil spring 58, the support member 55 hits the lower edge of the elongated hole 54, and further sliding of the lock member 48 is restricted, and the lock member 48 48 can be reliably returned to the original position.
[0036]
Then, as shown in FIG. 12, the upper lid 40 is moved in the direction of the arrow to close the opening 38. At this time, since the lock member 48 is returned to the original position, the lower end of the upper lid 40 hits the convex portion 52, but the inclined surface 44 is formed at the lower end of the upper lid 40, and the inner surface of the convex portion 52 is inclined. The surface 51 is formed, the inclined surface 44 and the inclined surface 51 come into contact with each other, and the convex portion 52 is pushed by the inclined surface 44 and temporarily moves downward, so that the upper lid 40 is locked to the convex portion 52. The upper lid 40 can be smoothly slid.
[0037]
When the tip of the upper lid 40 reaches the protrusion 56 of the lock member 48, the convex portion 52 matches the concave portion 43 of the upper lid 40, and the convex portion 52 enters the concave portion 43 of the upper lid 40 by the biasing force of the coil spring 27. Are securely locked, and this locked state can be reliably maintained.
[0038]
The main body 20A and the side plate 20B of the storage case 20 are both made of resin and are preferably made of the same material so as to have the same coefficient of thermal expansion. Further, the side plate 20B of the storage case 20 may be transparent or translucent so that the amount of chip components stored can be seen.
[0039]
The sliding structure of the lock member 48 in the vertical direction is not limited to the structure shown in the above embodiment. For example, the lock member 48 is formed with a ridge on one of the side wall and the side wall of the storage case. On the other hand, a groove may be formed corresponding to the protrusion, and the lock member 48 may be slidable.
[0040]
Further, the urging member of the lock member is not limited to the coil spring but may be a leaf spring.
[0041]
【The invention's effect】
As described above, in the invention according to claim 1 of the present application, the lock member can be slid by pushing it with the chip component replenishment case so that the lock can be released.
[0043]
In addition, since the urging member that urges the lock member upward is provided, the urging force of the urging member ensures that the upper lid is locked by the lock member, and this locked state can be reliably maintained.
[0044]
Also, a concave portion is formed on the lower surface of the opening and closing member, and an inclined surface is formed on the lower edge of the tip. Since the pressed part exposed to the side is integrally formed, when the lock member returns to the original position, the inclined surface of the lower end of the top lid and the inclined surface of the convex part of the lock member come into contact with each other, and the convex part Is pushed by the inclined surface of the upper lid and moves downward, so that the upper lid can be prevented from being locked to the convex portion, and the upper lid can be smoothly slid.
