The figure which shows the partial end surface of the cross section of the discharge cylinder vicinity part of a tray and the end surface of the cross section of a collection container for explaining another aspect of the fitting form of a discharge cylinder and a collection container (however, the metal mesh which covers a collection discharge port is provided FIG. 16 is a partial end face of the cross section of the vicinity of the discharge cylinder of the tray and the collection container for explaining still another aspect of the fitting form of the discharge cylinder of the tray and the collection container It is a figure which shows the end surface of the cross section of (However, the collection discharge port is covered. Is a diagram clearly that the wire mesh is provided).

  As shown in FIGS. 1 to 7, the tray 1 of the present embodiment has a cutting waste collecting and discharging port 2 in a part thereof, and the front surface of the receiving plate 1 faces the collecting and discharging port 2. In order to allow cutting waste to reach the collection discharge port 2, the inclined surface is formed to descend from the periphery of the tray 1 toward the collection discharge port 2. In other words, a concave surface is formed such that the collection discharge port 2 becomes the bottom surface of the front surface of the tray 1 from the periphery of the tray 1 toward the collection discharge port 2. The angle of the inclined surface cannot be generally defined because the slipperiness varies depending on the material of the tray, but is not particularly limited, but is preferably about 25 to 60 degrees with respect to the horizontal plane. The tray 1 of the present embodiment has a portion 11 in which the left and right edges of the tray 1 are lower than the other peripheral edges when viewed from the operator side. Therefore, it is possible to prevent the hand or arm from strongly hitting the edge of the saucer when the operator performs cutting work, to prevent the saucer from swinging, etc. This is a preferred mode in which it is possible to more surely solve problems such as being hard to work for a long time by striking the edge of the saucer strongly to reduce pain.

  The lower portion of the collection discharge port 2 has a discharge tube 3 protruding downward in a cylindrical shape, and a collection container 7 is disposed in the vicinity of the lower portion of the discharge tube 3 as shown in FIGS. And the transparent cutting waste scattering prevention wall 6 is provided in the position of the edge side by the side of an operator among the circumference | surroundings of the said saucer 1. FIG. The cutting dust scattering prevention wall 6 has its lower end fixed to a position on the edge side on the operator side in the periphery of the tray 1 by an appropriate means. It is preferable that the transparent cutting dust scattering prevention wall 6 is detachably fixed by an appropriate means such as a bolt nut, a screw, a clip or the like so that it can be replaced when the transparent swarf preventing wall 6 is damaged and becomes cloudy. FIG. 11 is a fragmentary end surface view of the portion using the mounting jig for the saucer 1 and the cutting dust scattering prevention wall 6 in order to explain an example of the mounting manner of the tray 1 and the cutting dust scattering prevention wall 6. A portion using the mounting jig is indicated by reference numeral 6b (6b in FIG. 8 also shows a portion using the same mounting jig). This mode is an example in which the tray 1 and the cutting dust scattering prevention wall 6 are attached with bolts 20 and nuts 21, but the mounting method is not limited to this mode, and the tray 1 and the cutting dust scattering prevention wall 6 are not limited thereto. Can be attached in any way as long as it is attached to the cutting work without any problem. In addition, since the receiving tray 1 and the cutting dust scattering prevention wall 6 are not limited to the joining aspect attached with the volt | bolt 20 and the nut 21 as mentioned above, in various explanatory drawings (FIGS. 1-7, FIG. 13, FIG. 14 etc.) of a receiving tray. The holes for bolts are not specified.

  In this aspect, as illustrated in FIGS. 8 and 9, the collection outlet 2 is provided with a metal mesh 5 that covers the collection outlet 2, and the metal mesh 5 is subjected to cutting processing though cutting scraps pass through it. Metal dentures containing noble metals or metal prostheses containing noble metals are made of open metal meshes that do not pass through them. Even when an object is dropped on the tray, the metal denture or metal prosthesis can be prevented from entering the collection container 7 by the wire mesh 5, so that the collection container 7 is removed and the metal denture or metal prosthesis is removed. This is preferable because it is not necessary to take out an object from the collection container 7.

  8 and 9, the precious metal scrap collecting apparatus for dental technician work includes a cap 7a and a container body 7b, and the discharge cylinder 3 is detachably attached to the cap 7a of the collecting container. It is inserted to be fixed to. The cap 7a and the container body 7b are screwed together by screw mechanisms 8 and 9 and fixed. Further, on the outer side of the lower part of the collection container, there is provided a fall prevention base 10 on which the collection container can be fitted on the outer peripheral side of the bottom of the collection container. The material of the tipping prevention base 10 is not particularly limited as long as it can prevent the tipping, and examples thereof include wood, metal, stone, cement, and plaster.

  FIG. 12 shows a perspective view of an example of the transparent cutting dust scattering prevention wall 6 used in the present invention. As is clear from FIGS. 8 and 9, the transparent cutting dust scattering prevention wall 6 is slightly bent so as to cover the upper side of the tray 1. It is preferable from the viewpoint of more reliably dropping the cutting waste on the tray. 8, 9, and 12, 6 a indicates a bent portion of the cutting dust scattering prevention wall. However, the shape is not limited to this shape and this position, and the cutting waste is bent in an arc shape. Other embodiments may be used as long as the space between the tray and the cutting dust scattering prevention wall is not so narrow that the operation on the tray of the operator's hand can be disturbed when working. Moreover, although the cutting dust scattering prevention wall which stands upright with respect to the horizontal direction and extends upward can be used, in addition to this aspect, the cutting dust scattering prevention wall is not bent in the middle and has a surface that extends flatly upward. In the cutting dust scattering prevention wall, a cutting dust scattering prevention wall attached at an angle with respect to the horizontal direction so as to cover the upper portion of the tray 1 may be adopted. The cutting dust scattering prevention wall covers the upper side of the saucer 1 as shown in FIGS. 8 and 9 from the viewpoint of preventing the work of the arm and the like from being disturbed and more reliably dropping the waste on the saucer. It is preferable that the surface is slightly bent so as to be covered.

  In the cutting dust scattering prevention wall 6, as shown in FIGS. 8 and 12, a substantially U-shaped cutting is provided at the end of the cutting dust scattering prevention wall 6 opposite to the side fixed to the tray 1. By providing the notch 12, even when the transparency of the anti-scattering wall is reduced due to the collision of the scraps scattered with the anti-scattering wall, the operator can remove the gap between the substantially U-shaped notches 12 during the work. Therefore, it is also preferable from the viewpoint that the position of the processing object can be clearly confirmed, and the position of the processing object can be visually recognized without substantially reducing the function of preventing the scattering of the cutting waste. . The substantially U-shaped notch is not limited to the U-shape, and may be any shape such as a V-shape, a rectangle, a square, a triangle, an ellipse, a circle, or a star. Good. Further, as described above, the tray 1 and the cutting dust scattering prevention wall 6 are not limited to the joining mode in which the bolt and the nut are attached as described above, and therefore, the hole through which the bolt passes is not clearly shown in FIG.

  The material of the anti-scattering wall is not particularly limited as long as the material can exhibit its function, and examples thereof include a transparent plate or a transparent plate such as glass.

  Next, FIG. 10 shows a noble metal scrap collecting apparatus for dental technician work according to another aspect of the present invention. FIG. 10 is an end view of a cross section corresponding to the direction DD ′ of FIG. The main difference from the precious metal scrap collecting apparatus shown in FIGS. 8 and 9 is that the collecting container is a collecting container 7 having a wide bottom, and therefore the collecting is performed like the embodiment shown in FIGS. 8 and 9. This is an aspect that does not require the tipping prevention base 10 into which the collection container can be fitted on the outer peripheral side of the bottom of the container 7. Further, the discharge cylinder 3 and the collection container 7 are fitted so that the fitting of the discharge cylinder 3 and the collection container 7 is detachably fixed to the opening of the collection container 7. If necessary, a packing or the like may be interposed between the discharge tube 3 and the opening of the collection container 7. Other parts similar to those in FIGS. 8 and 9 are denoted by the same reference numerals as those in FIGS. 8 and 9, and redundant description is omitted.

  FIG. 15 is a view showing a partial end face of a cross section of a portion near the discharge cylinder of the tray and an end face of the cross section of the collection container for explaining an example of another mode of fitting the discharge cylinder of the tray and the collection container. In this way, the fitting mechanism of the discharge cylinder 3 and the collection container 7 forms the threads 24 and 23 on the inner peripheral side of the opening of the collection container 7 and the outer periphery of the discharge cylinder 3, respectively, and these are screwed together. It may be in the form. Other parts similar to those in FIGS. 8 and 9 are denoted by the same reference numerals as those in FIGS. 8 and 9, and redundant description is omitted.

  Further, FIG. 16 is a view showing a partial end face of the cross section of the vicinity of the discharge cylinder of the tray and an end face of the cross section of the collection container for explaining another example of the fitting form of the discharge cylinder of the tray and the collection container. However, in this way, the fitting mechanism of the discharge cylinder 3 and the collection container 7 forms the threads 28 and 26 on the outer peripheral side of the opening of the collection container 7 and the inner peripheral part of the discharge cylinder 3, respectively. You may make it an embodiment to do. Other parts similar to those in FIGS. 8 and 9 are denoted by the same reference numerals as those in FIGS. 8 and 9, and redundant description is omitted.

  Although not shown in the figure, in the case where the tray is in a self-supporting state such as having a leg portion or supported by an appropriate stand, the fall prevention stand 10 shown in FIGS. In addition, it is not always necessary that the outer wall of the discharge cylinder and the inner wall of the collection container entrance are in close contact with each other, and the outer wall diameter of the discharge cylinder is smaller than the inner wall diameter of the collection container entrance and the outer wall of the discharge cylinder. There may be a mode in which a gap is opened between the inner wall of the collection container entrance part, or the lower edge of the discharge tube and the upper edge of the collection container opening are separated from each other vertically and below the lower edge of the discharge tube. The collection container may be arranged so that the upper end edge of the collection container opening is located. In this case, the inner diameter of the lower edge of the discharge tube is preferably smaller than the inner diameter of the upper edge of the collection container opening.

  The planar shape seen from the top of the saucer 1 shown in FIGS. 1, 2, 8, etc. shows a substantially rectangular saucer, but the planar shape seen from the top of the saucer is not limited to this. However, the present invention is not limited in any way as long as it is possible to collect scraps of precious metals for dental technician work and achieve the object of the present invention.

  A few examples of the saucer according to another aspect will be described. FIG. 13 is a schematic plan view seen from the front surface of the saucer according to another aspect used in the precious metal scrap collecting apparatus for dental technician work of the present invention. FIG. 14 is an example of a long horseshoe-shaped saucer in which a plan view viewed from the front surface of the saucer is a combination of a substantially semi-ellipse and a square. The same parts as those in FIG. 1 and FIG. 2 are denoted by the same reference numerals, and redundant description is omitted. Although not shown in the drawings, the plan view seen from the front surface of the saucer is substantially polygonal, substantially circular, substantially elliptical, etc. other than the above, and the plan view seen from the top of the saucer is just an example. However, the present invention is not limited to this as long as it can collect scraps of precious metals for dental work and can achieve the object of the present invention.

  The position of the collection / discharge port for the cutting waste formed on the tray is not particularly limited as long as the cutting waste can reach the collection / discharge port. It is preferable not to be biased toward the edge side, but to be provided at a position between the vicinity of the center on the left and right sides, and in the front-rear direction, from a position near the middle of the front and back to the vicinity of the worker-side edge.

  If the receiving surface has an inclined surface that is lowered from the periphery of the tray toward the collection discharge port so that cutting waste can reach the collection discharge port toward the collection discharge port Well, the inclination angle and the like vary depending on the material of the tray and the processing state of the front surface, and are not particularly limited. For example, the angle is 25 to the outer peripheral edge of the tray from the collection outlet to the horizontal plane. A range of about ˜60 degrees is preferable, and if the direction from the collection outlet of the tray toward the outer peripheral edge of the tray is different, the inclination angle in the AA ′ direction and the inclination angle in the BB ′ direction in FIG. The tilt angle in the direction and the tilt angle in the DD ′ direction need not be the same. For example, taking an example of the tilt angle in the DD ′ direction, the tilt angle from the collection outlet to the D direction and the collection Heading in the D 'direction from the outlet It may be different oblique angle is the same for the other direction. Similarly, for example, taking an inclination angle from the collection outlet to the D direction as an example, the inclination angle does not have to be the same at any position from the collection outlet to the D direction from the collection outlet. It may change depending on the position from the collection outlet. On the premise that the inclined surface that descends from the circumference of the saucer toward the collection outlet is satisfied, for example, it is a downwardly convex substantially arc shape or a polygonal line graph, or upward The shape may be a convex substantially circular arc shape or a polygonal line shape of a line graph, as long as cutting waste can reach the collection discharge port toward the collection discharge port. Here, “cutting scraps can reach the collection / discharge port” means that cutting scraps remain on the front surface of the saucer while the object is being cut. If vibration is given, it means that cutting waste can easily reach the collection outlet.

  The material of the saucer is not particularly limited as long as the cutting waste is a material that can reach the collection discharge port as described above, iron, copper, stainless steel, plated steel plate, brass, aluminum and other metals, Representative examples include styrene resins, olefin resins, polyester resins, phenol resins, acrylic resins, and various plastics.

  The shape of the collection and discharge port for cutting waste of the tray of the present invention and the shape of the discharge cylinder are not limited to a circular shape and a cylindrical shape, respectively, and any shape can be used as long as the cutting waste can be discharged. A square shape (including a star shape) or a cross-sectional shape of the discharge tube may be a triangle or more polygon (including a star shape).

  As described above, the scrap collecting apparatus for precious metals for dental technician work of the present invention is not limited to the above-described embodiment specifically described, and in accordance with the spirit of the present invention, Should be determined based on the description.
