Description

【Technical Field】 【0001】 The present invention relates to a powder supply device and a powder supply method for inhaling and discharging powder. 【Background Art】 【0002】 There is known a powder supply device called a powder pipette that inhales a desired amount of powder into a chip having a filter and discharges it at a desired position. For example, Patent Document 1 discloses a powder dispensing device including a powder dispensing chip having a filter with pores, a nozzle having a tip for detachably holding the chip, a pump, means for connecting the nozzle to the suction side of the pump, means for connecting the nozzle to the discharge side of the pump, and means for switching between the two means. 【0003】 When inhaling powder with a powder pipette, there are problems such as excess powder adhering to the outer peripheral portion of the chip, resulting in a measurement error due to the excess powder, and excess powder falling in an unintended location. Therefore, FIG. 3 of Patent Document 2 discloses, as a prior art, providing a powder dropping table having a hole with a predetermined clearance with respect to the outer periphery of the filling piston to drop the extra powder adhering to the outer periphery, and removing the extra powder adhering below the lower end surface of the filling piston by masking. Further, FIG. 1 of Patent Document 2 discloses a powder dropping table provided with a filter communicating with a vacuum source. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. Hei 10-263421 【Patent Document 2】 Japanese Utility Model Publication No. Sho 64-11921 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 According to the method disclosed in Patent Document 2, it is possible to remove some of the excess powder adhering to the filling piston. However, since the mechanism for removing excess powder from the outer surface of the filling piston is through sliding with the solid powder layer 17, there is a problem that some powder remains on the outer surface of the filling piston that cannot be removed. Furthermore, the method described in Patent Document 2 requires the preparation of a powder drop platform having a filter that communicates with a vacuum source, which presents the challenge of making the apparatus compact. 【0006】 Furthermore, the process for supplying the powder was complex, as it required inserting a filling piston into the holes of the powder dropper to fill the powder, and then performing a mesh cut to remove excess powder from the lower end of the filling piston. 【0007】 The present invention aims to provide a powder supply device and a powder supply method that can remove excess powder adhering to a suction measuring device having a weighing chamber and a suction port in a simple process.

[Modes for carrying out the invention] 【0013】 The following describes examples of embodiments for carrying out the present invention. The powder supply device 1 of this embodiment includes a powder weighing device 10 and powder removal brushes (20, 30). 【0014】 <Powder measuring device 10> Figure 1 is a side view showing the powder weighing device 10. The powder weighing device 10 mainly consists of a main body 11, a nozzle 12 extending from the lower end of the main body 11, and a tip (suction weighing device) 13 attached to the tip of the nozzle 12, and is also called a powder pipette. 【0015】 The main body 11 can apply negative pressure to the internal space of the nozzle 12 by an external or internal negative pressure source (not shown). The cylindrical nozzle 12 has a tip 13 detachably attached to its end. The tip 13 consists of a mounting portion 131 into which the nozzle 12 is inserted, and a suction portion 132 extending downward from the mounting portion 131 and having a smaller diameter than the mounting portion 131. An inlet 133 opening downward is provided at the lower end of the suction portion 132 of the tip 13. The tip 13 is a known tip, generally made of resin material and disposable. The shape of the tip 13 is not limited to the cylindrical shape exemplified, and any shape of tip, including a tapered shape, can be used. In this specification, the tip 13 may be referred to as a suction measuring device. The tip is not limited to being made of resin, but may be made of metal such as aluminum or stainless steel, glass, or paper. 【0016】 The powder weighing device 10 in this embodiment is used to draw in a desired amount of powder by inserting the lower end of the suction portion 132 of the tip 13 into the powder stored in the powder tank, and then discharge the powder after moving it to a predetermined position. When performing this operation, a problem arises in which excess powder adheres to the tip of the tip 13. The problem of excess powder adhering to the tip of the tip 13 will be explained below with reference to Figures 2 to 4. 【0017】 Figure 2 is a transparent side view of the main part showing the tip of the tip 13 attached to the powder weighing device 10 of the embodiment example embedded in the powder 102 in the powder tank 101. As shown in Figure 2, the mounting portion 131 of the tip 13 has a stepped channel consisting of a large-diameter channel 131a and a small-diameter channel 131b. The tip of the nozzle 12 is inserted into the large-diameter channel 131a and is fixed in contact with a stepped portion provided at the upper end of the small-diameter channel 131b. Note that the fixing of the nozzle and tip is not limited to fixing in contact with the stepped portion, but may also be fixed by a taper. 【0018】 A filter 14 is positioned within the intake section 132 of the tip 13 at a certain distance from the intake port 133. The space between the filter 14 and the intake port 133 within the tip 13 constitutes the metering chamber 15. When aspirating powder, the main body 11 is moved above the powder tank 101 by a relative mobile robot (not shown), and then the main body 11 is lowered by another relative mobile robot (not shown) so that the tip of the tip 13 is embedded in the powder 102 to a depth D. The powder tank 101 stores powder 102 such as a sample. The depth D is variable depending on the application. 【0019】 Figure 3 is a transparent side view of the main part showing the state in which powder 102 has been sucked and filled into the weighing chamber 15 of the powder weighing device 10 from the state shown in Figure 2. When sucking powder 102 into the weighing chamber 15, with the tip of the tip 13 embedded in the powder 102 to a depth D, the main body 11 applies negative pressure to the internal space of the nozzle 12 from a negative pressure source such as a pump (not shown). As a result, negative pressure is also applied to the internal space of the tip 13, which is in communication with the internal space of the nozzle 12, and the powder 102 is sucked into the weighing chamber 15 from the intake port 133 of the tip 13. The filter 14 provided at the upper end of the weighing chamber 15 has a pore structure with a coarseness that allows gas to pass through but not powder 102, so the powder 102 sucked in from the intake port 133 is stored in the weighing chamber 15. The timing of applying negative pressure from the negative pressure source to the nozzle 12 can be automatically controlled by a control device (not shown). It goes without saying that the aforementioned control device can regulate the pressure to a desired negative pressure. 【0020】 Figure 4 is a transparent side view of the main part showing the state in which the tip 13 of the powder weighing device 10 has been raised from the powder tank, compared to the state in Figure 3. When the main body 11 is raised by a relative mobile robot (not shown), excess powder 103 adheres to the outer surface near the tip of the suction part 132 of the tip 13. In addition, excess powder 104, held by negative pressure, protrudes from the suction port 133 and adheres to the tip of the tip 13. If the excess powder 103 on the outer surface of the tip 13 and the excess powder 104 at the tip are discharged together when the powder in the weighing chamber 15 is discharged, it will cause supply amount errors. 【0021】 Furthermore, excess powder 103 and 104 may fall due to airflow or slight vibrations when the powder weighing device 10 is moved to the supply location, potentially contaminating the work environment. The following describes a method for removing excess powder adhering to the outer surface and tip of the tip 13. 【0022】 <First powder removal brush 20> As shown in Figures 5(a) and (b), the first powder removal brush 20 is composed of a bristle member 21 and brush bristles 22. Note that in Figure 5, for ease of explanation, the brush bristles 22 are depicted as thicker than they actually are. 【0023】 One end of the brush bristles 22 is implanted on the side surface of the bristle-implanted member 21. The brush bristles 22 are composed of groups of elastic bristles of the same length and diameter extending along the extension direction 23. As materials for the bristles 22, for example, synthetic resin bristles, synthetic fibers, various animal hairs or various plant fibers, and materials in which some or all of these are imparted with conductivity can be used. In the bristle-implanted member 21 shown in Figure 5, the side surface on which the brush bristles 22 are implanted is flat, but the side surface of the bristle-implanted member 21 may be a curved arc shape, and the brush bristles 22 may be implanted there. Furthermore, the brush bristles 22 may be composed of a combination of groups of elastic bristles of different lengths and / or different diameters. 【0024】 The brush bristles 22 have three layers of bristles, consisting of an upper layer, a middle layer, and a lower layer, which are arranged at equal intervals in a first direction of travel 24 perpendicular to the extension direction 23. In other words, the brush bristles 22 in the embodiment have a three-tiered laminated bristle structure, which is constructed by stacking three brush layers in the vertical direction. In the embodiment, the extension direction 23 of each brush layer is horizontal, but each brush layer may be arranged so that its extension direction is at an angle of less than 90 degrees to the horizontal direction. Furthermore, the laminated bristle structure of the brush bristles 22 of the first powder removal brush 20 is not limited to the three layers exemplified, but may be two layers or four or more layers. 【0025】 The first powder removal brush 20 is used by bringing the tip 13 into contact with the first side surface 25, and then moving the tip 13 along the first direction of travel 24 while elastically deforming the brush bristles 22. Figure 5(a) shows the first powder removal brush 20 of Figure 5(b) is a perspective view showing how excess powder is removed by bringing the tip 13 into contact with the first side surface 25, and is a side view of Figure 5(a). The first powder removal brush 20 is held in place by a brush holder (not shown), and the tip 13 is moved by a relative mobile robot (not shown). 【0026】 (1) Removal of excess powder 103 from the outer surface of the chip 13 Figure 6 is a plan view showing the usage of the first powder removal brush 20, where (a) shows the powder removal brush in the first position, (b) shows the powder removal brush in the second position, (c) shows the powder removal brush in the third position, and (d) shows the powder removal brush in the fourth position. 【0027】 After the powder 102 is sucked in, the powder weighing device 10 moves the tip 13 to a position facing the first side surface 25 of the first powder removal brush 20 by a relative movement robot (not shown) (see Figure 6(a)). Here, the horizontal position of the tip 13 relative to the first powder removal brush 20 is near the tip of the bristles. butInstead of positioning the tip 13 directly against the brush bristles, position the tip 13 should contact the brush bristles 22 closer to the root than the tip. For example, the tip 13 should contact the brush bristles 22 at a point between 3 / 4 and 1 / 8 or 2 / 3 and 1 / 6 of the length L of the brush bristles 22, starting from the tip. 【0028】 Next, when the tip 13 is advanced along the first direction of travel 24 by a relative mobile robot (not shown), the tip 13 comes into contact with the first side surface 25. As the tip 13 continues to advance along the first direction of travel 24, the brush bristles 22 that are in contact with the tip 13 undergo elastic deformation and come into close contact with the outer circumferential surface of the tip 13 on the bristle member 21 side, thereby scraping off excess powder 103 adhering to the outer circumferential surface of the tip 13 on the bristle member 21 side (see Figure 6(b)). 【0029】 Furthermore, as the tip 13 is advanced along the first direction of travel 24, the bristles 22 near the second side surface 26 opposite the first side surface 25 also come into contact with the tip 13 and undergo elastic deformation, while the bristles 22 near the first side surface 25 lose contact with the tip 13 and return to their original position (see Figure 6(c)). Further, as the tip 13 is moved along the first direction of travel 24, all contact between the bristles 22 and the tip 13 is eliminated, and all bristles 22 return to their original positions (see Figure 6(d)). In this way, by moving the tip 13 along the first direction of travel 24 so that it passes from the first side surface 25 to the second side surface 26 of the first powder removal brush 20, it is possible to clean the excess powder 103 adhering to half of the outer circumference of the tip 13 (the side with the bristled member 21) with the first powder removal brush 20. 【0030】 After cleaning by moving the tip 13 along the first direction of travel 24, the outer surface on the opposite side of the tip 13 (the lower side in Figure 6) may be cleaned by moving it along the second direction of travel 27, which is opposite to the first direction of travel 24. Since the outer surface on the side of the direction of travel, which is the first to be contacted by the brush bristles 22, is subjected to a stronger scraping action by the brush bristles 22 compared to the outer surface on the opposite side of the direction of travel, a higher cleaning effect can be obtained by cleaning while moving along the second direction of travel 27. 【0031】 Furthermore, by cleaning the remaining half of the outer surface of the tip 13 (the side opposite to the bristle member 21) with the first powder removal brush 20, it is possible to remove excess powder 103 adhering to the entire outer surface of the tip 13. As described above, when moving the tip 13 along the second direction of travel 27, the main body 11 may be rotated 180 degrees to clean the outer surface of the tip 13 on the side that has not been cleaned (the side opposite to the bristle member 21). A preferred embodiment includes a second powder removal brush 30, which will be described later. 【0032】 (2) Removal of excess powder 104 from the tip of the tip 13 Figures 7(a) and 7(b) illustrate how the first powder removal brush 20 removes excess powder 104 from the tip of the chip 13. For illustrative purposes, the brush bristles 22 in Figure 7 are depicted as being thicker than they actually are. 【0033】 The excess powder 104 at the tip of the tip 13 is removed by the upper surface of the lower layer of brush bristles 22 of the first powder removal brush 20, which scrapes off the powder adhering to the tip surface of the tip 13. Here, it is preferable that the vertical position where the tip of the tip 13 contacts the brush 20 is within a range of 2 / 3 of the height H of the brush bristles 22 from the lower end of the brush bristles 22. It is preferable that the upper surface of the middle or lower layer of brush bristles 22 of the first powder removal brush 20 contacts the tip of the tip 13, but this contact is not essential. If there are brush bristles 22 located directly below the tip of the tip 13, it is possible to remove the excess powder 104 that has protruded from the tip of the tip 13. 【0034】 Furthermore, if only the lower layer of brush bristles 22 is located below the tip of the tip 13, the upper and middle layers of brush bristles 22 will scrape the sides of the tip 13. To effectively remove excess powder 103 from the side surface of the tip 13 while simultaneously removing excess powder 104 from the tip 13, it is exemplified that the thickness (height H) of the first powder removal brush 20 be 5 mm to 60 mm or 10 mm to 50 mm. From another point of view, it is preferable that the height H of the first powder removal brush 20 be greater than the depth D (see Figure 2) to which the tip 13 is embedded in the powder 102. When the relationship "height H > depth D" is satisfied, it is possible to remove excess powder 104 from the tip of the tip 13 while simultaneously removing excess powder 103 from the side surface of the tip 13. Since the depth D varies depending on the application, it is preferable to set the thickness (height H) of the first powder removal brush 20 so that it can accommodate various applications. 【0035】 If the height H is less than or equal to the depth D, the effects of the present invention can be achieved by first moving the tip 13 relative to the first powder removal brush 20 to remove excess powder 103 above the side surface of the tip 13, and then moving the tip 13 relative to the first powder removal brush 20 again to remove excess powder 103 and excess powder 104 below the side surface of the tip 13. 【0036】 Furthermore, it is preferable to position the tip 13 so that it is located at a buffer distance B from the tip of the brush bristles 22 towards the base, so that the tip of the brush bristles 22 does not enter the suction port 133 and scrape out the powder in the weighing chamber 15 (see Figure 7(b)). For example, the tip 13 is positioned so that it contacts the brush bristles 22 from the tip of the brush bristles 22 in the range of 3 / 4 to 1 / 8 or 2 / 3 to 1 / 6 of the length L of the brush bristles 22. 【0037】 Figures 8(a) to 8(f) are side views of the first powder removal brush 20 as seen from the tip side of the brush bristles 22, showing the brush 20 in positions a to f, respectively. In Figure 8(a), the upper layer of the brush 22 is indicated by reference numeral 22a, the middle layer by reference numeral 22b, and the lower layer by reference numeral 22c. As shown in Figure 8(a), the chip 13 at position a has its lower end positioned between the middle layer 22b and the lower layer 22c in the vertical direction. 【0038】 As shown in Figure 8(b), the tip 13 moves from position a toward the first direction of travel 24, and when it reaches position b, the side surface of the tip 13 comes into contact with the upper layer of brush bristles 22a and the middle layer of brush bristles 22b. 【0039】 As shown in Figure 8(c), when the tip 13 moves from position b toward the first direction of travel 24 and reaches position c, the upper layer of brush bristles 22a1 and the middle layer of brush bristles 22b1 constituting the first side surface 25 are elastically deformed by the pressure of the tip 13, and the excess powder 104 protruding from the tip of the tip 13 is rubbed off by the lower layer of brush bristles 22c1. At this time, the tip of the tip 13 and the lower layer of brush bristles 22c may or may not be in contact. In addition, the middle layer of brush bristles 22b may deform so as to slip under the tip of the tip 13, and the excess powder 104 protruding from the tip of the tip 13 may be rubbed off by the middle layer of brush bristles 22b. 【0040】 As shown in Figure 8(d), when the tip 13 moves from position c toward the first direction of travel 24 and reaches position d, the upper bristles 22a1 and middle bristles 22b1 constituting the first side surface 25 are released from contact with the tip 13 and return to their original positions. The upper bristles 22a2 and middle bristles 22b2 adjacent to the upper bristles 22a1 and middle bristles 22b1 are elastically deformed by the pressure of the tip 13. 【0041】 As shown in Figure 8(e), when the tip 13 moves from position d toward the first direction of travel 24 and reaches position e, the upper brush bristles 22a2 and the middle brush bristles 22b2 are released from contact with the tip 13 and return to their original positions. The upper brush bristles 22a3 and the middle brush bristles 22b3 adjacent to the upper brush bristles 22a2 and the middle brush bristles 22b2 are elastically deformed by the pressure of the tip 13. 【0042】 As shown in Figure 8(f), when the tip 13 moves from position e toward the first direction of travel 24 and reaches position f, the upper brush bristles 22a3 and the middle brush bristles 22b3 release contact with the tip 13 and return to their original positions. 【0043】 As described above, as the tip 13 moves from position a to position f, the excess powder 103 on the side surface of the tip 13 and the excess powder 104 protruding from the tip are removed by the first powder removal brush 20. 【0044】 <Second powder removal brush 30> As shown in Figure 9, a preferred embodiment includes a second powder removal brush 30 positioned opposite the first powder removal brush 20. The configuration of the second powder removal brush 30 is the same as that of the first powder removal brush 20, and includes a bristle member 31 and brush bristles 32. 【0045】 The second powder removal brush 30 is positioned so that its bristles face the first powder removal brush 20. A gap G is provided between the first powder removal brush 20 and the second powder removal brush 30. In Figure 9, the bristle flocking member 21 and the bristle flocking member 31 are shown as separate members, but they may be formed from a single integrated member. The sides to which the brush bristles 22 and 32 of the first powder removal brush 20 and the second powder removal brush 30 are flocked may be curved rather than flat. The first powder removal brush 20 and the second powder removal brush 30 do not need to be positioned parallel to each other; they may be positioned such that the intersection of their extensions forms an acute angle (for example, less than 45 degrees). The bristle flocking members 21 and 31 may also be formed integrally, for example, by integrally forming C-shaped, V-shaped, or U-shaped (half-bracket shaped) bristle flocking members. 【0046】 Chip 13 is moved along the path shown in the order of the circled numbers 1 through 6 in Figure 9. First, the tip 13 moves along the width direction W of the brush 21 from position number 1 to position number 2, thereby removing excess powder 103 adhering to the left half-circumferential surface and excess powder 104 protruding from the tip. Figure 10(a) shows the tip 13 in the process of moving from position number 1 to position number 2. 【0047】 Next, the tip 13 folds back from position number 2 to position number 3, thereby removing excess powder 103 adhering to the left half-circumferential surface and excess powder 104 protruding from the tip. Figure 10(b) shows the tip 13 in the process of moving from position number 2 to position number 3. Note that the movement path from position number 2 to position number 3 may be the same as the movement path from position number 1 to position number 2. 【0048】 The back-and-forth movement of the brush bristles 22, from circled numbers 1 to 3, removes excess powder 103 adhering to the left half-circumferential surface of the tip 13 and excess powder 104 protruding from the tip. 【0049】 Next, the tip 13 moves from the position marked with circle number 3 to the position marked with circle number 4, and the second powder removal brush 30 performs the operation of removing excess powder 103 mainly attached to the right half of the circumference. 【0050】 First, as the tip 13 moves from the position marked with circle number 4 to the position marked with circle number 5, excess powder 103 adhering to the right half-circumferential surface and excess powder 104 at the tip that could not be completely removed are removed. Figure 10(c) shows the tip 13 in the process of moving from the position marked with circle number 4 to the position marked with circle number 5. 【0051】 Next, chip 13 folds back from the position of circled number 5 to the position of circled number 6, right Excess powder 103 adhering to the half-circumferential surface and excess powder 104 at the tip that could not be completely removed are removed. Figure 10(d) shows the tip 13 in transit from the position of circled number 5 to the position of circled number 6. Note that the path from the position of circled number 5 to the position of circled number 6 may be the same as the path from the position of circled number 4 to the position of circled number 5. 【0052】 The back-and-forth movement of the brush bristles 32, from circled numbers 4 to 6, removes excess powder 103 adhering to the right half-circumferential surface of the tip 13 and the powder that could not be removed by the first powder removal brush 20. tta The excess powder 104 at the tip is removed. 【0053】 As described above, according to the embodiment of the preferred model, excess powder 103 attached to the entire circumferential surface of the tip 13 can be reliably removed by the first powder removal brush 20 and the second powder removal brush 30. In Figure 9, as indicated by the circled numbers 2 and 5, the tip 13 is moved to a position where contact with the brush bristles 22 and 32 of the brushes 20 and 30 is completely released. However, even if the return movement is started while contact with the brush bristles 22 and 32 is not released, a sufficient effect of removing excess powder can be obtained. 【0054】 <Third powder removal brush 40> As shown in Figure 11, the embodiment according to Modification 1 includes a third powder removal brush 40 provided opposite the first powder removal brush 20. The configuration of the third powder removal brush 40 is the same as that of the first powder removal brush 20, and includes a bristle member 41 and brush bristles 42. 【0055】 The third powder removal brush 40 is positioned so that its bristles face the first powder removal brush 20. Furthermore, the bristles of the first powder removal brush 20 and the third powder removal brush 40 overlap. 【0056】 Chip 13 is moved along the path shown in the order of the circled numbers 1 through 3 in Figure 12. First, as the tip 13 moves from position number 1 to position number 2, excess powder 103 adhering to its entire surface and excess powder 104 protruding from its tip are removed. Figures 12(a) to (d) show the tip 13 in the process of moving from position number 1 to position number 2. 【0057】 Next, the tip 13 folds back from position number 2 to position number 3, removing any excess powder 103 adhering to the entire surface that could not be removed, as well as any excess powder 104 protruding from the tip. Figures 12(d) to (g) show the tip 13 in the process of moving from position number 2 to position number 3. Note that the path from position number 2 to position number 3 may be the same as the path from position number 1 to position number 2. 【0058】 The back-and-forth movement of the circled numbers 1 to 3 across the brush bristles 22, 42 removes excess powder 103 adhering to the entire surface of the tip 13 and excess powder 104 protruding from the tip. 【0059】 As described above, according to Modification 1, the excess powder 103 attached to the entire surface of the chip 13 is removed by the first powder removal brush 20 and the third powder removal brush 40 with a shorter travel distance of the chip 13 than in Figure 9 (i.e., one round trip). twistSince it can be removed, the cleaning time for tip 13 can be shortened. In Figures 11 and 12, as indicated by the circled number 2, tip 13 is moved to a position where contact with the brush bristles 22 and 42 of brushes 20 and 40 is completely released. However, even if the return movement is started while contact with the brush bristles 22 and 42 is not released, sufficient excess powder removal can be obtained. 【0060】 <Powder Removal Brush 50> As shown in Figure 13(a), the embodiment of the modified example 2 includes a fourth powder removal brush 50. The fourth powder removal brush 50 comprises an annular bristle member 51 and brush bristles 52. 【0061】 The annular bristle member 51 has brush bristles 52 that extend toward the center implanted on its inner circumferential surface. The length of the brush bristles 52 is such that a central hole 53 is formed in the center of the powder removal brush 50. In the example shown in Figure 13(a), the bristle member 51 is made up of a single annular member, but the bristle member 51 may also be made up of multiple bristle members, each with an arc-shaped inner circumferential surface on which brush bristles 52 are implanted. 【0062】 When removing excess powder 103 from the side surface and excess powder 104 from the tip of the tip 13, first insert the tip 13 into the central hole 53 and adjust the height of the tip 13. This height adjustment is the same as in the example in Figure 7 above. Alternatively, the tip 13 may be inserted not into the central hole 53, but closer to the base of the tip of the brush 52 to adjust the height of the tip 13. Next, move the tip 13 closer to the base of the tip of the brush bristles 52, and move the tip 13 in a circular motion clockwise or counterclockwise to remove the excess powder 103 from the side surface and excess powder 104 from the tip of the tip 13. 【0063】 <Powder Removal Brush 60> As shown in Figure 13(b), the embodiment according to the modified example 3 includes a fifth powder removal brush 60. The fifth powder removal brush 60 comprises an annular bristle member 61 and brush bristles 62. The annular bristle-flocked member 61 has brush bristles 62 extending radially from its outer surface. Here, the bristle-flocked member 61 may be made up of a disc-shaped or cylindrical member. 【0064】 When removing excess powder 103 from the side surface and excess powder 104 from the tip of the tip 13, first adjust the height of the tip 13. This height adjustment is the same as in the example shown in Figure 7 above. Next, move the tip 13 closer to the base than the tip of the brush bristles 62, and move the tip 13 in a circular motion clockwise or counterclockwise to remove the excess powder 103 from the side surface and excess powder 104 from the tip of the tip 13. Alternatively, the height adjustment of the tip 13 may be performed after moving the tip 13 closer to the base than the tip of the brush bristles 62. 【0065】 <Powder tank cover member 70> In a preferred embodiment, the powder tank cover member 70 is composed of a first powder removal brush 20 and a second powder removal brush 30, as described with reference to Figures 9 and 10. 【0066】 As shown in Figure 14, the first powder removal brush 20 and the second powder removal brush 30 are positioned above the powder tank 101 by a support (not shown) to constitute the powder tank cover member 70 (see Figure 23, described later). The width W of the first powder removal brush 20 and the second powder removal brush 30 (see Figure 9) has an area that can cover all or part of the powder tank 101. 【0067】 When the powder weighing device 10 sucks up the powder 102, the tip 13 is inserted into the gap G or brush bristles 22, 32 of the first powder removal brush 20 and the second powder removal brush 30. Excess powder 103, 104 adhering to the tip 13 during the powder suction operation is removed by moving the tip 13 relative to the first powder removal brush 20 and the second powder removal brush 30, and falls into the powder tank 101. Since the first powder removal brush 20 and the second powder removal brush 30 are positioned directly above the powder tank 101, the distance that the powder weighing device 10 needs to move to remove the excess powder 103, 104 is minimized. 【0068】 The powder tank cover member 70 described above has the effect of preventing the scattered powder 105 inside the powder tank 101 from scattering to the outside. It also has the effect of preventing external dust 106 from mixing into the powder tank 101. A vibration device may be provided to the powder tank cover member 70 to apply vibration, and the powder tank cover member 70 may be vibrated when removing excess powder 103, 104. Alternatively, the vibration from this vibration device may be transmitted to vibrate the powder tank 101. 【0069】 <Powder tank cover component 170 with electrostatic discharge function> Figure 15 is a side view of the powder tank cover member 170 with an electrostatic discharge function. The tip 13 is generally made of a resin material, and excess powder adheres to the tip and outer surface of the tip 13 due to static electricity. This is effective in removing such excess powder that adheres due to static electricity. 【0070】 The sixth powder removal brush 80 and the seventh powder removal brush 90 are both formed with some or all of their brush bristles 82, 92 made of conductive material bristles that have an antistatic effect. Examples of conductive material bristles include nylon coated with conductive carbon, acrylic or nylon fibers chemically bonded with copper sulfide, and composites of nylon and carbon-containing conductive materials. The bristle members 81, 91 to which the brush bristles 82, 92 are implanted are also made of conductive material. With brush bristles 82, 92 made of conductive material, static electricity can be instantly discharged by corona discharge generated when the tip 13 comes into contact with the bristles. However, to enhance the antistatic effect, it is preferable to connect an earth wire 171 to the bristle members 81, 91. In Figure 15, only the sixth powder removal brush 80 is provided with an earth wire 171, but the seventh powder removal brush 90 can also be provided with an earth wire. 【0071】 By moving the tip 13 relative to the sixth powder removal brush 80 and the seventh powder removal brush 90 along the path shown in Figure 9 above, excess powder adhering to the tip 13 can be removed. 【0072】 The powder tank cover member 170 described above not only functions as a cover to prevent the scattering of powder in the powder tank 101 and the intrusion of dust from the outside, but can also effectively remove excess statically charged powder adhering to the tip and outer surface of the tip 13 through its static elimination function. It goes without saying that the static elimination brush is not limited to use as a powder tank cover member, and that the static elimination function can also be added to a brush alone without a powder tank. 【0073】 <Multi-tiered powder tank cover member 270> Figure 16 is a side view of a multi-stage powder tank cover member 270. This powder tank cover member 270 comprises a lower cover member equipped with a first powder removal brush 20 and a second powder removal brush 30, and an upper cover member equipped with an eighth powder removal brush 220 and a ninth powder removal brush 230. 【0074】 The eighth powder removal brush 220 has the same configuration as the first powder removal brush 20 and comprises a bristle member 221 and brush bristles 222. The ninth powder removal brush 230 has the same configuration as the second powder removal brush 30 and comprises a bristle member 231 and brush bristles 232. The powder removal brushes (20, 30) that constitute the lower cover member and the powder removal brushes (220, 230) that constitute the upper cover member are supported by a support (not shown). 【0075】 In Figure 16, the powder removal brushes (20, 30) constituting the lower cover member and the powder removal brushes (220, 230) constituting the upper cover member are depicted separately, but it is also possible to place them in close proximity. In this case, excess powder adhering to the chip 13 can be removed not only by the first powder removal brush 20 and the second powder removal brush 30, but also by the eighth powder removal brush 220 and the ninth powder removal brush 230. 【0076】 According to the multi-stage powder tank cover member 270 shown in Figure 16, when removing excess powder adhering to the tip and outer surface of the chip 13 with the first powder removal brush 20 and the second powder removal brush 30, the excess powder that scatters upward can be contained by the upper cover members (220, 230). 【0077】 <Attachment-type powder tank cover component 370> Figure 17(a) is a side view of an attachment-type powder tank cover member 370 of an embodiment example. The attachment-type powder tank cover member 370 comprises flocked members 321 and 331 that can be attached to the powder tank 101, and brush bristles 322 and 332. The flocked members 321 and 331 are integrally formed. The flocked members 321 and 331 each have hook-shaped engaging portions 321a and 331a, and by engaging the engaging portions 321a and 331a with the powder tank 101, the powder tank cover member 370 can be easily attached to the powder tank 101. 【0078】 As shown in Figure 17(a), the powder tank cover member 370 has brush bristles 322 and 332 arranged inside the powder tank 101, making it possible to more effectively prevent the powder 102 inside the powder tank 101 from scattering to the outside. Alternatively, a vibration device may be provided to the powder tank cover member 370 to vibrate it when removing excess powder 103 and 104. Furthermore, the vibration from this vibration device may be transmitted to vibrate the powder tank 101. 【0079】 <Self-standing powder tank cover component 470> Figure 17(b) is a side view of a self-supporting powder tank cover member 470 of an embodiment example. The self-supporting powder tank cover member 470 comprises self-supporting flocked members 421 and 431 and brush bristles 422 and 432 within the powder tank 101. The flocked members 421 and 431 are integrally formed. The flocked members 421 and 431 each have grounding portions 421a and 431a, and by grounding the grounding portions 421a and 431a onto the powder 102 within the powder tank 101, the powder tank cover member 470 can be made self-supporting within the powder tank 101. 【0080】 As shown in Figure 17(b), the powder tank cover member 470 has brush bristles 422 and 432 positioned inside the powder tank 101, making it possible to more effectively prevent the powder 102 inside the powder tank 101 from scattering to the outside. Furthermore, since it can be installed in any powder tank 101 with an inner diameter that accommodates the powder tank cover member 470, it can be applied to powder tanks 101 of various sizes. 【0081】 <Various Rotating Devices> The powder supply device 1 equipped with the powder tank cover member (70, 370) described above can be fitted with various rotating devices that rotate the chip 13 and the powder tank cover member (70, 370) relative to each other. The rotational operation described below may be either clockwise or counterclockwise. 【0082】 Figure 18(a) is a side view showing a configuration in the powder supply device 1 of Figure 14 in which a chip rotating device is provided to rotate the powder weighing device 10 with the vertical direction as the axis of rotation. Disclosed as the chip rotating device is, for example, a rotating device such as a motor that rotates the nozzle 12 on the main body 11, or mounting the powder weighing device 10 on a relative mobile robot (not shown) via a rotating device such as a motor that rotates the powder weighing device 10. When moving the chip 13 along the path of Figure 9 by a relative mobile robot (not shown), it is possible to more effectively remove excess powder (103, 104) adhering to the chip 13 by combining it with the rotational operation of the chip rotating device. Alternatively, when the chip 13 is stopped, the chip rotating device alone may be rotated to remove excess powder (103, 104) adhering to the chip 13. 【0083】 Figure 18(b) is a side view showing a configuration in the powder supply device 1 of Figure 14, in which a cover member rotating device is provided to rotate the powder tank cover member 70 with the vertical direction as the axis of rotation. As the cover member rotating device, for example, a rotating device such as a motor is disclosed to be provided on the support of the powder tank cover member 70. When moving the chip 13 along the path of Figure 9 with a relative mobile robot (not shown), it is possible to more effectively remove excess powder (103, 104) adhering to the chip 13 by combining it with the rotational operation of the cover member rotating device. Alternatively, when the chip 13 is stopped, the excess powder (103, 104) adhering to the chip 13 may be removed by rotating only the cover member rotating device. 【0084】 Figure 18(c) is a side view showing a configuration in the powder supply device 1 of Figure 17(a) in which a powder tank rotating device is provided to rotate the powder tank 101 with the vertical direction as the axis of rotation. As the powder tank rotating device, for example, a rotating device such as a motor is disclosed to be provided on the table on which the powder tank is placed. When moving the chip 13 along the path of Figure 9 by a relative mobile robot (not shown), it is possible to more effectively remove excess powder (103, 104) adhering to the chip 13 by combining it with the rotation operation of the powder tank rotating device. When the chip 13 is stopped, the powder tank rotating device alone may be rotated to remove excess powder (103, 104) adhering to the chip 13. Alternatively, a vibrating device that vibrates the table on which the powder tank is placed may be provided in combination with the rotating device. 【0085】 <Powder suction device 180,333> Figure 19(a) is a perspective view showing the powder removal brush 20 and powder suction device 180, and Figure 19(b) is a side view thereof. The powder suction device 180 is equipped with a suction port 181 that communicates with a negative pressure source (not shown) via an on / off valve, and sucks up excess powder 103, 104 removed from the tip 13 by the brush bristles 22 from the suction port 181. The powder suction device 180, which is located below the bristle member 21, may be connected to the lower surface of the bristle member 21 or to a support that supports the powder removal brush 20. The timing of generating negative pressure at the suction port 181 can be automatically controlled by a control device (not shown). 【0086】 Figure 19(c) is a side view showing a tenth powder removal brush 320, in which a suction port 323 is provided on a bristle member 321. Brush bristles 322 are implanted on the side of the bristle member 321, and multiple suction ports 323 are provided on the portion of the same side where brush bristles 322 are not implanted. In other words, a powder suction device 333 is provided on the bristle member 321. The suction ports 323 are in communication with a negative pressure source (not shown) via an on / off valve, and the excess powder 103, 104 removed from the tip 13 by the brush bristles 322 is sucked out through the suction ports 323. The timing of generating negative pressure at the suction ports 323 can be automatically controlled by a control device (not shown). 【0087】 As described above, the powder suction devices 180 and 333 make it possible to prevent excess powder 103 and 104 removed from the tip 13 from scattering to the outside. The powder suction devices 180 and 333 are also applicable to the powder removal brushes shown in Figures 9 to 18. 【0088】 <Powder removal brushes 620, 630> Figure 20(a) is a side view showing the 11th powder removal brush 620 and the 12th powder removal brush 630. The 11th powder removal brush 620 comprises a bristle member 621 arranged such that the side facing the brush bristles 622 is angled upward, and the brush bristles 622. 【0089】 On the side of the bristle-planted member 621, which is positioned to face diagonally upward, the bristles are planted such that the base portion 622a of the bristles extends in a direction perpendicular to the side of the bristle-planted member 621. The reason the base portion 622a is extended diagonally upward is that sagging occurs due to the weight of the bristles at the central portion 622b and the tip portion 622c. In other words, the bristles 622 are designed so that the bristles extend horizontally at the central portion 622b and the tip portion 622c, taking into account the sagging due to the weight of the bristles, by extending the base portion 622a diagonally upward. Note that the effects of the present invention are achieved if either the central portion 622b or the tip portion 622c of the bristles extends horizontally. 【0090】 A twelfth powder removal brush 630 is provided such that the tip portions 622c and 632c of the eleventh powder removal brush 620 face each other. The configuration of the twelfth powder removal brush 630 is the same as that of the eleventh powder removal brush 620, and it comprises a bristle member 631 and brush bristles 632. The bristles of the twelfth powder removal brush 630 are also planted on the bristle member 631 such that the brush bristles 632 extend diagonally upward at the base portion 632a. That is, the brush bristles 632 of the twelfth powder removal brush 630 are designed so that the bristles extend horizontally at the central portion 632b and the tip portion 632c, taking into account the sagging due to the weight of the brush bristles, and the base portion 632a is extended diagonally upward. Note that the effects of the present invention are achieved if either the central portion 632b or the tip portion 632c of the brush bristles extends horizontally. 【0091】 When removing excess powder 103,104 adhering to the tip 13 using the 11th powder removal brush 620 and the 12th powder removal brush 630, it is preferable to bring the tip 13 into contact with the central portion 622b,632b or the tip portion 622c,632c of the horizontally extending brush bristles. For example, by moving the tip 13 along the path indicated by the circled numbers in Figure 9 or Figure 11, the excess powder 103,104 can be removed. Note that the central portion 622b,632b in Figure 20(a) refers to the portion between the base portion 622a,632a and the tip portion 622c,632c. 【0092】 Figure 20(b) is a side view showing the 13th powder removal brush 720 and the 14th powder removal brush 730. The 13th powder removal brush 720 has a bristle member 721 similar to the first powder removal brush 20, but differs in that the base portion 722a of the brush bristles 722 is planted so as to extend diagonally upward. It also differs from the 11th powder removal brush 620 in that the side surface on which the brush bristles of the bristle member 721 are planted is arranged parallel to the vertical direction, and the tips of the brush bristles 722 are aligned on the same plane parallel to the vertical direction. 【0093】 The 13th powder removal brush 720 has its base portion 722a extended diagonally upward to account for the sagging due to the weight of the brush bristles, so that the bristles extend horizontally in the central portion 722b and the tip portion 722c. In other words, the brush bristles 722 have their base portion 722a extended diagonally upward to account for the sagging due to the weight of the brush bristles, so that the bristles extend horizontally in the central portion 722b and the tip portion 722c. The tip portion 722c of the brush bristles is configured so that the tips of the bristles from the upper layer to the lower layer are located on a plane parallel to the vertical direction. Note that the effects of the present invention are achieved if either the central portion 722b or the tip portion 722c of the brush bristles extends horizontally. 【0094】 A 14th powder removal brush 730 is provided such that the tip portions 722c and 732c of the 13th powder removal brush 720 face each other. The configuration of the 14th powder removal brush 730 is the same as that of the 13th powder removal brush 720, and it comprises a bristle member 731 and brush bristles 732. The brush bristles 732 of the 14th powder removal brush 730 are configured such that the bristles extend horizontally in the central portion 732b and the tip portion 732c, and the base portion 732a is extended diagonally upward to account for the sagging due to the weight of the brush bristles. The tip portion 732c of the brush bristles is configured such that the tips of the bristles from the upper layer to the lower layer are located on a plane parallel to the vertical direction. Note that the effects of the present invention are achieved if either the central portion 732b or the tip portion 732c of the brush bristles extends horizontally. 【0095】 When removing excess powder 103,104 adhering to the tip 13 with the 13th powder removal brush 720 and the 14th powder removal brush 730, it is preferable to bring the tip 13 into contact with the central part 722b,732b or the tip part 722c,732c of the horizontally extending brush bristles (for example, the path shown in Figure 9 or Figure 11). The 13th powder removal brush 720 and the 14th powder removal brush 730 are configured such that the gaps between the brush bristles 722,732 are uniform from the upper layer to the lower layer, making it possible to widen the sweet spot of the tip part 722c,732c for removing excess powder 103,104 from the tip 13 compared to the 11th powder removal brush 620 and the 12th powder removal brush 630. Note that in Figure 20(b), the central portion 722b, 732b refers to the portion between the base portion 722a, 732a and the tip portion 722c, 732c. 【0096】 <Brush guide members 841-844> Figure 21(a) is a side view showing the 15th powder removal brush 820, the 16th powder removal brush 830, the first brush guide member 841, and the second brush guide member 842. The 15th powder removal brush 820 comprises a bristle member 821 positioned such that the side facing the brush bristles 822 is obliquely downward, and the brush bristles 822. Below the central portion 822b of the brush bristles is a first brush guide member 841 having a flat upper surface. On the obliquely downward-facing side of the bristle member 821, the root portion 822a of the brush bristles is planted so as to extend in a direction perpendicular to the side of the bristle member 821, and the central portion 822b is in contact with the first brush guide member 841. Due to the guiding action of the first brush guide member 841, the central portion 822b and the tip portion 822c of the brush bristles are extended horizontally. Note that the effects of the present invention are achieved if either the central portion 822b or the tip portion 822c of the brush bristles is extended horizontally. 【0097】 A 16th powder removal brush 830 is provided such that the tip portions 822c and 832c of the 15th powder removal brush 820 face each other. The configuration of the 16th powder removal brush 830 is the same as that of the 15th powder removal brush 820, and it comprises a bristle member 831 and brush bristles 832. Below the central portion 832b of the brush bristles, a second brush guide member 842 having a flat upper surface is positioned. The central portion 832b of the brush bristles, which extends diagonally downward from the side of the bristle member 831, is in contact with the second brush guide member 842. Due to the guiding action of the second brush guide member 842, the central portion 832b and the tip portion 832c of the brush bristles are extended horizontally. Note that the effects of the present invention are achieved if either the central portion 832b or the tip portion 832c of the brush bristles is extended horizontally. 【0098】 The first and second brush guide members 841 and 842 function as guide plates that support the brush bristles 822 and 832 from below. Therefore, even if the bristles are long enough to hang down due to their own weight, it is possible to extend the central portions 822b and 832b and the tip portions 822c and 832c of the brush bristles 822 and 832 horizontally. The first and second brush guide members 841 and 842 are connected to and fixed to a support that supports the powder removal brushes 820 and 830, for example. When removing excess powder 103,104 adhering to the tip 13 with the 15th powder removal brush 820 and the 16th powder removal brush 830, it is preferable to bring the tip 13 into contact with the brushes in a path that passes between the first and second brush guide members 841,842 (for example, the path shown in Figure 9 or Figure 11). 【0099】 Figure 21(b) is a side view showing the 17th powder removal brush 920, the 18th powder removal brush 930, the first brush guide member 841, and the second brush guide member 842. The first and second brush guide members 841 and 842 are the same as those in Figure 21(a), so their description is omitted. The 17th powder removal brush 920 has a bristle member 921 similar to the first powder removal brush 20, but differs in that the base portion 922a of the brush bristles 922 is planted so as to extend diagonally downward. It also differs from the 15th powder removal brush 820 in that the side surface on which the brush bristles of the bristle member 921 are planted is arranged to be parallel to the vertical direction, and the tips of the brush bristles 922 are aligned on the same plane parallel to the vertical direction. 【0100】 In the 17th powder removal brush 920, the bristles at the central portion 922b and the tip portion 922c are extended horizontally due to the guiding action of the first brush guide member 841. Furthermore, the 17th powder removal brush 920 is configured such that the tips of the bristles from the upper layer to the lower layer are located on a plane parallel to the vertical direction. Note that the effects of the present invention are achieved if either the central portion 922b or the tip portion 922c of the bristles is extended horizontally. 【0101】 The 18th powder removal brush 930 has the same configuration as the 17th powder removal brush 920, comprising a bristle member 931 and brush bristles 932. Similar to the 17th powder removal brush 920, the 18th powder removal brush 930 also has the bristles of the central portion 932b and the tip portion 932c extended horizontally due to the guiding action of the second brush guide member 842. Furthermore, the 18th powder removal brush 930 is configured such that the tips of the bristles from the upper layer to the lower layer are located on a plane parallel to the vertical direction. Note that the effects of the present invention are achieved if either the central portion 932b or the tip portion 932c of the brush bristles is extended horizontally. 【0102】 When removing excess powder 103,104 adhering to the tip 13 using the 17th powder removal brush 920 and the 18th powder removal brush 930, it is preferable to bring the tip 13 into contact with the brush in a path that passes between the first and second guide members 841,842 (for example, the path shown in Figure 9 or Figure 11). The 17th powder removal brush 920 and the 18th powder removal brush 930 are configured such that the gaps between the brush bristles 922,932 are uniform from the upper layer to the lower layer, making it possible to widen the sweet spot of the tip portions 922c,932c for removing excess powder 103,104 from the tip 13 compared to the 15th powder removal brush 820 and the 16th powder removal brush 830. 【0103】 Figures 21(a) and (b) illustrate a configuration in which a pair of powder removal brushes are pressed against the first and second brush guide members 841 and 842. However, as shown in Figures 14 to 18, it is also possible to combine a powder removal brush with horizontally extending bristles with the first and second brush guide members 841 and 842. Furthermore, the brush guide members can also be applied to a single powder removal brush 20. 【0104】 The bristles of a powder removal brush have the problem of spreading vertically at the tips after prolonged use, but this problem can be solved by providing a brush guide member. Figure 21(c) is a side view showing the first powder removal brush 20, the second powder removal brush 30, and the first to fourth brush guide members 841 to 844. The first powder removal brush 20 and the second powder removal brush 30 have already been explained with reference to Figures 9 and 10, so their explanation will be omitted here. 【0105】 A first brush guide member 841 is positioned below the brush bristles 22, in close proximity to or in contact with them. A second brush guide member 842 is positioned below the brush bristles 32, in close proximity to or in contact with them. A third brush guide member 843 is positioned above the brush bristles 22, in close proximity to or in contact with them. A fourth brush guide member 844 is positioned above the brush bristles 32, in close proximity to or in contact with them. In the illustrated example, the third brush guide member 843, which has the same shape as the first brush guide member 841, is positioned opposite each other. However, their shapes do not necessarily have to be identical, and their centers may be offset. The same applies to the second brush guide member 842 and the fourth brush guide member 844. 【0106】 When removing excess powder 103,104 adhering to the tip 13 with the first powder removal brush 20 and the second powder removal brush 30, it is preferable to bring the tip 13 into contact with the brushes in a path that passes between the first to fourth brush guide members 841 to 844 (for example, the path shown in Figure 9 or Figure 11). According to the configuration in Figure 21(c), it is possible to prevent the problem of the brush bristles of the powder removal brushes 20 and 30 spreading out vertically at the tip due to prolonged use. 【0107】 The details of the present invention will be described below with reference to examples, but the technical concept of the present invention is not limited in any way to these examples. [Examples] 【0108】 <Structure> Figure 22 is a perspective view of the tabletop powder supply device 1 according to Example 1. The powder weighing device 510 has the same configuration as the powder weighing device 10 shown in Figure 1, and comprises a main body 511 and a nozzle 512. It is used with a tip 13 attached to the tip of the nozzle 512. The powder weighing device 510 is mounted on a Z-direction drive unit 503 such that the extension direction of the nozzle 512 is vertical, allowing for positioning in the Z direction (vertical direction). The Z-direction drive unit 503 is mounted on a gantry-type Y-direction drive unit 502, allowing for positioning in the Y direction. The worktable 504 on which the powder tank 101 and other items that the powder weighing device 510 will work with is mounted on an X-direction drive unit 501, allowing for positioning in the X direction. The X-direction drive unit 501 is positioned on a frame 508. In this specification, the XYZ direction drive units (501, 502, 503) may be referred to as relative mobile robots. 【0109】 The control device 520 is a computer equipped with a processing unit and a memory device. - The control device 520 is a controller that stores a control program in its memory that controls the operation of the powder weighing device 510 and the XYZ direction drive devices (501, 502, 503). The control device 520 controls the XYZ direction drive devices (501, 502, 503) to position the powder weighing device 510 at any coordinate on the work table 504. The control device 520 also controls the operation of a switching valve (not shown) that connects or disconnects the nozzle 512 of the powder weighing device 510 from a negative pressure source (not shown). The control device 520 also controls the operation of the vibration device 540, which will be described later. 【0110】 Figure 23 is a perspective view of the brush device 530 and vibrator device 540 according to Example 1. The brush device 530 is composed of bristle members 531, 532 and brush bristles 533, 534, and is supported by a support 535. The support 535 is connected to the vibrating table 542 of the vibrating device 540. Here, unlike the example in Figure 23, the support 535 may be connected to the work table 504. The bristle-flocked members 531 and 532 are columnar members with brush bristles 533 and 534 flocked to their inner surfaces, respectively, and are connected to the support member 535. 【0111】 The brush bristles 533 and 534 are the same as the brush bristles 22 and 32 in the above-described embodiment example, and are composed of groups of elastic bristles of the same length and diameter. The brush bristles 533 and 534 are arranged so that their tips face each other, with a gap between them. The width in the extension direction of the bristle flocking members 531 and 532 of the brush bristles 533 and 534 is large enough to cover a part of the opening of the powder tank 101. When lowering the tip 13 into the powder tank 101, lowering it at a position not covered by the brush bristles 533 and 534 or at a position with a gap can prevent dust adhering to the brush bristles 533 and 534 from mixing into the tip 13 or the powder tank 101 due to contact during the lowering of the tip 13. However, under usage conditions where the problem of dust adhering to the brush bristles 533 and 534 does not occur, the tip 13 may be lowered at a position covered by the brush bristles 533 and 534. The powder is stored in the cylindrical container, the powder tank 101. The shape of the powder tank 101 is not limited to the cylindrical shape shown in the example; any shape of powder tank, including bottles and bags, can be used. 【0112】 The vibration device 540 comprises a vibration table 541 and a vibration table 542, and is fixed to the work table 504 by a fixing device 543. The fixing device 543 may be integrally configured with the support device 535 described above. Alternatively, unlike this embodiment, a vibration device that vibrates the brush device 530 may be provided, and the powder tank 101 may be vibrated by vibrations transmitted via the support device 535. The vibration table 541 is equipped with a vibration device such as a motor, and the ON / OFF operation of the vibration device is controlled by the control device 520. The vibration table 542 is a table on which the powder tank 101 is placed, and the brush device 530 described above is connected to it via a support 535. The vibration table 542 may be provided with a holding mechanism for holding the powder tank 101. The vibration table 541 is fixed to the work table 504 by a fixing device 543 and is moved in the X direction together with the work table 504 by an X direction drive device 501. 【0113】 <Powder supply operation> The operation of supplying powder to a powder tray using the powder weighing device 510 will now be explained. Here, it is assumed that the nozzle 512 of the powder weighing device 510 already has an appropriate tip 13 attached, and that a powder tray (not shown) is placed on the work table 504. First, the control device 520 moves the powder weighing device 510 above the powder tank 101 and lowers the nozzle 512 to bury the tip of the tip 13 into the powder in the powder tank 101. Next, the control device 520 connects the nozzle 512 to a negative pressure source (not shown) and sucks the powder into the weighing chamber 15 inside the tip 13. A filter 14 is placed inside the tip 13 that defines the upper end of the weighing chamber 15, and the powder fills the weighing chamber 15 due to the action of negative pressure (see Figure 3). 【0114】 When drawing powder into the weighing chamber 15 from the tip of the embedded chip 13, the powder tank 101 is vibrated by the vibrator 540. This is because, although indentations are created on the surface of the powder in the powder tank 101 due to the indentation, vibrating the powder tank 101 allows surrounding powder to flow into the indentations, thus leveling the unevenness of the powder surface. Indentations on the surface of the powder in the powder tank 101 are undesirable because they can cause air to be drawn in or result in uneven suction flow rates. When the powder tank 101 is vibrated by the vibrator 540, the vibration is also transmitted to the chip 13 via the powder. By vibrating the chip 13, the powder drawn into the weighing chamber 15 is uniformly dispersed, which also has the effect of keeping the bulk density constant. In addition to this, the powder may be drawn into the weighing chamber 15 while vibration is applied to the powder weighing device 510. 【0115】 Once the powder has been filled into the weighing chamber 15, the Z-direction drive device 503 is driven to vertically position the powder weighing device 510 in order to remove excess powder. The control device 520 positions the device such that the tip of the tip 13 is positioned on the upper surface of the bottommost layer of brush bristles 533, 534, as shown in Figure 7 or Figure 8. Next, the control device 520 moves the chip 13 and the brush device 530 relative to each other using the X-direction drive device 501 and the Y-direction drive device 502, for example, so that the chip 13 moves along a path as shown in Figure 9. This removes excess powder (103, 104) from the tip and side surfaces of the chip 13. 【0116】 Once the removal of excess powder (103, 104) from the tip and side surface of the tip 13 is complete, the control device 520 drives the XYZ direction drive devices (501, 502, 503) to move the powder weighing device 510 above the powder tray (not shown), releases the negative pressure from the negative pressure source acting in the weighing chamber 15, or applies positive pressure, to discharge the powder from the weighing chamber 15 into the powder tray (not shown). At this time, vibration may be applied to the tip 13 to promote discharge. 【0117】 Once all dispensing operations for the same type of powder are completed, the control device 520 drives the XYZ direction drive devices (501, 502, 503) to move the powder weighing device 510 to the tip removal jig 505 and detach the tip 13 from the tip of the nozzle 512. The detached tip 13 is discharged into the tip waste tray 506. If there is subsequent dispensing operations for a different type of powder, a new tip 13 from the tip tray 507 is attached to the nozzle 512, and the powder suction operation for the powder tank 101 containing the different type of powder is performed using the same procedure. At this time, it is preferable to also replace the brush device 530 with a new one. 【0118】 According to the powder supply device 1 of Example 1 described above, after metering and sucking up the powder, excess powder (103, 104) adhering to the tip and side surface of the tip 13 can be automatically removed, enabling highly accurate metering and dispensing. Furthermore, by vibrating the powder tank 101 with the vibrator 540 while sucking up the powder, it becomes possible to fill the metering chamber 15 with powder at a constant bulk density. [Examples] 【0119】 The powder supply device 201 according to Example 2 differs from the powder supply device 1 according to Example 1 mainly in that the powder weighing device 610 has a flexible pipe 612. The following will focus on the differences from Example 1, and elements identical to those in Example 1 will be denoted by the same reference numerals in the drawings and described accordingly. omission do. 【0120】 Figure 24 is a side view of a powder weighing device 610 according to Embodiment 2. This powder weighing device 610 comprises a main body 611 that applies negative pressure to a flexible pipe 612, and the flexible pipe 612. The flexible pipe 612 is made of a flexible tube, and the tip 612a of the flexible pipe constitutes a nozzle. A tip 613 is detachably attached to the tip 612a of the flexible pipe. Unlike the illustrated example, a nozzle member may be connected to the tip 612a of the flexible pipe, and the flexible pipe 612 and the tip 613 may be indirectly connected via the nozzle member. For example, a nozzle head 619, which will be described later, may be used as the nozzle member, and the tip 613 may be detachably attached to a cylindrical tip mounting portion provided on the nozzle head 619. 【0121】 Tip 613 is a disposable type equipped with an inlet 614, a metering chamber 615, a filter 616, a suction section 617 having an internal space communicating with a flexible pipe 612, and a mounting section 618 for attaching to the flexible pipe 612. Negative pressure is applied to the metering chamber 615 from the main body 611 via the flexible pipe 612 and the filter 616. Tip 613 is the same as tip 13 except that the metering chamber 615 and the suction section 617 are frustoconical. 【0122】 Figure 25 is a perspective view of the powder supply device 201 according to Example 2. The powder weighing device 610 has its main body 611 located outside the frame 508. In the illustrated example, the main body 611 is installed on top of the control device 520, but the main body 611 can be installed in any location, and the main body 611 can also be built into the frame 508. 【0123】 One end of the flexible pipe 612 extends from the main body 611, and the other end is inserted into the nozzle head 619. A tip 613 is attached to the tip 612a of the flexible pipe extending from the nozzle head 619. The nozzle head 619 is mounted on a Z-direction drive unit 503, allowing for positioning in the Z direction (vertical direction). The Z-direction drive unit 503 is mounted on a Y-direction drive unit 502, allowing for positioning in the Y direction. The work table 504 is mounted on an X-direction drive unit 501, allowing for positioning in the X direction. The brush device 530 and vibrator 540 installed on the work table 504 are the same as in Embodiment 1. The modifications of these devices described in Embodiment 1 are also applicable to Embodiment 2. 【0124】 flexible piping 6 12 can deform and follow the movement of the nozzle head 619, and can apply negative pressure supplied from the main body 611 to the nozzle head 619 at any position. The method for removing excess powder adhering to the tip and outer surface of the tip 613 by the brush device 530 is the same as in Example 1. Also, the method of sucking up powder while vibrating the powder tank 101 with the vibrator 540 is the same as in Example 1. 【0125】 As described above, the powder supply device 201 of Example 2 automatically removes excess powder adhering to the tip and side surface of the tip 613 after metering and suction of the powder, enabling highly accurate metering and dispensing. Furthermore, by suctioning the powder while vibrating the powder tank 101 with the vibrator 540, it is possible to fill the metering chamber 615 with powder at a constant bulk density.
