  As such a powder cutting device, for example, in Patent Document 1, a fixed portion that can be fixed by fixing a raw material container provided with a powder cutting portion at the lower side of the side surface, and a vibration generating portion that is integrally connected to the fixed portion, There has been proposed a discharge drive unit comprising: a discharge drive unit that is swingably supported by a plurality of springs. In the powder cutting device described in Patent Document 1, the raw material container is transported and fixed to a fixed part, and the powder or powder in the raw material container is shaken by applying vibration from the vibration generating part. Is cut out from the powder cut-out portion and supplied to a measuring container, and the weight thereof is measured.

Japanese Patent No. 3799440

  However, in the cutting device that vibrates the raw material container fixed to the fixing part in this way and cuts out the powder, when the amount of powder cut out at a time is large and the raw material container becomes large, the transport means for transporting the raw material container also includes Along with the increase in size, a vibration generating unit also requires a vibrator with a large output, which inevitably increases the size and cost of the entire device. In addition, since the powder cutout part for discharging the powder is fixed to the raw material container, for example, even when it is desired to clean only the cutout part, the entire raw material container must be cleaned, and a large-scale work is required.

  The present invention has been made under such a background, and it is possible to avoid an increase in size and cost of the apparatus, and to provide a vibrating powder cutting apparatus that can be easily cleaned and cleaned. It is aimed.

  In order to solve the above problems and achieve such an object, according to the present invention, a plurality of hoppers containing powder are fixed to the upper part of the base, and the respective hoppers are respectively discharged under the hopper discharge ports. The trough is provided so as to be movable up and down, and the discharge trough is supported by the base when it is in the non-cutout position on the lower end side of the vertical movement, and is in a cutout position above the noncutout position. Sometimes the base and the hopper are in a non-engaged state and can be vibrated, while the lower part of the base is provided with a carriage that can move below the discharge trough of each fixed hopper. Further, a vibrator provided on the carriage so as to be movable up and down can be engaged with and disengaged from the discharge trough located above.

  In the vibratory powder cutting apparatus configured as described above, the powder stored in the hopper as the raw material container is once discharged from the hopper discharge port to the discharge trough, and the discharge trough is vibrated by the vibrator. It will be cut out. That is, when the powder is not cut out, the discharge troughs that are provided in a plurality of hoppers so as to be movable up and down are arranged at the non-cutting position on the lower end side of the vertical movement by their own weight and supported by the base, Part of the powder is held in a state where it flows into the discharge trough from the hopper discharge port.

  In order to cut out and discharge the powder from such a state, the carriage below the base is moved to be positioned below the discharge trough that discharges the powder, and then the vibrator is raised to engage the discharge trough. Combine. Further, when the vibrator is further raised, the discharge trough is also raised and arranged at the cutout position above the noncutout position, and is allowed to vibrate in a non-engaged state with the base and the hopper. When the exhaust trough is vibrated by a vibrator in the state, the powder that has flowed into the discharge trough is cut out from the trough discharge port of the discharge trough and discharged, and the powder continues to flow into the discharge trough from the hopper Be made.

  In addition, the powder thus cut and discharged is weighed while being stored in, for example, a measuring container, and when a predetermined amount of powder is cut and discharged, the vibration of the vibrator is stopped and the discharge trough is stopped. By releasing the vibrator and lowering the vibrator, the discharge trough is also lowered and returned to the non-cutting position and supported by the base again, so that part of the powder in the hopper is also a hopper discharge port. From the exhaust trough. Therefore, by moving the carriage below the discharge trough of the next hopper and performing the same operation, the powder stored in the plurality of hoppers can be sequentially cut out and discharged.

  Thus, in the vibratory powder cutting device having the above-described configuration, the powder can be cut out and discharged by a single vibrator provided in the moving carriage for a plurality of fixed hoppers. As the amount of powder to be accommodated increases as the hopper is transported and the hopper increases in size, there is no situation where the transport means must be increased in size. In addition, when the powder is cut out, the vibrator need only vibrate the discharge trough without vibrating the entire hopper, so there is no need to enlarge the vibrator even if the hopper is enlarged. Therefore, it is possible to prevent the entire cutting device from becoming large and to prevent the cost from becoming high.

  The discharge troughs provided for the hoppers fixed to the upper part of the base are movable up and down, that is, separate from the hoppers. For this reason, even when cleaning the discharge trough, it is not necessary to clean the entire hopper, it is possible to remove and clean only the discharge trough after closing the hopper discharge port, making cleaning and cleaning easy. Can be performed.

  Here, as described above, the discharge trough is supported by the base at the non-cutout position, and can be vibrated in a non-engaged state with respect to the base and the hopper at the cutout position, and is given from the vibrator. In order to enable the powder to be cut out and discharged by vibration, for example, the discharge trough may be suspended from the base by an elastic member such as a coil spring. In this case, the discharge trough is stabilized at the non-cutting position. Otherwise, the powder may inadvertently leak out.

  Therefore, in order to support the discharge trough in the non-cutout position on the base and to disengage the cutout position in this way, the discharge trough is supported by a through-hole penetrating in the vertical direction. And a shaft-like support member extending downward at the upper portion of the base. The upper shaft portion of the support member has a smaller diameter than the through hole, while the lower end portion of the support member. Is larger in diameter than the upper shaft portion and the through hole, and the upper trough portion of the support member is inserted into the through hole so that the discharge trough is suspended from the base at the non-cutting position. It is desirable to do so.

  That is, when the discharge trough is attached in this manner, the discharge trough is moved up and down by inserting the upper shaft portion of the support member into the through hole of the supported portion, and the non-cutting position on the lower end side of this vertical movement The discharge trough is stably supported by being in contact with the lower end portion of the support member whose supported portion has a diameter larger than that of the through hole. When the discharge trough is arranged at the cutout position above the non-cutout position by being engaged with the vibrator and raised as described above, the through hole of the supported portion and the smaller diameter than this. Since there is a space between the upper shaft portion of the supporting member, the powder can be cut out by vibrating the discharge trough without interfering with the supporting member.

  In particular, when the discharge trough is supported by such a support member, the outer peripheral surface of the lower end portion of the support member and the inner peripheral surface of the through hole of the supported portion of the discharge trough are gradually expanded downward. When the discharge trough descending with the vibrator returns to the non-cutting position by cutting the powder into a conical surface having a diameter, the conical surfaces of the inner and outer peripheral surfaces are in close contact with each other so that the discharge trough is in the horizontal direction. Therefore, the discharge trough can be supported more stably at the non-cutout position and at the fixed position.

  Furthermore, it is desirable to provide a lid for closing the trough discharge port at the trough discharge port of the discharge trough to prevent the powder from leaking out at the non-cutting position where the powder is not cut out. If the body is attached to the discharge trough itself, when the discharge trough is vibrated to cut out and discharge the powder, the lid may close and the powder may not be discharged. .

  Therefore, it is desirable that the lid for closing the trough discharge port of the discharge trough at the non-cutout position is provided on the base side. At this time, the lid body can be opened and closed in a state of being biased toward the trough discharge port side, and opening / closing means for opening and closing the lid body is provided on the cart side, so that the powder is cut out. When the carriage moves to the position of the hopper to be discharged, the lid can be opened by this opening / closing means and the powder can be discharged through the discharge trough, so that the lid can be opened / closed by one opening / closing means as in the case of the vibrator. Can be more efficient.

  On the other hand, even if the discharge trough can be supported at a fixed position in the non-cutting position in this way, if the movement of the carriage cannot be accurately controlled, the position is below the discharge trough of the hopper for cutting the powder. When the cart vibrator is raised, it becomes difficult to vibrate the exhaust trough with the vibrator securely by, for example, mechanical engagement / disengagement means. However, it is not easy to accurately control the movement of the carriage including the heavy vibrator.

  Therefore, as an engagement / disengagement means that makes it possible to engage and disengage the vibrator and the exhaust trough, the exhaust trough is formed of a material such as an iron material that can be adsorbed to the magnet, or such a portion that engages with the vibrator of the exhaust trough On the other hand, if the vibrator is equipped with an electromagnet on the top of the vibrator and the exhaust trough is attracted and desorbed to the electromagnet, the vibrator can be engaged with and detached from the exhaust trough. In addition, even if the movement of the carriage is not controlled, the discharge trough can be reliably engaged with the vibrator and vibrated only by switching the energization to the electromagnet.

  Furthermore, since the carriage is moved to the position of the hopper that always cuts out and discharges the powder among the plurality of hoppers, the carriage is below the trough discharge port of the discharge trough positioned above the vibrator. The weighing container is disposed so as to be positioned at the same time, and a weighing device for weighing the powder discharged into the weighing container is provided, so that the weight of the powder cut out and discharged can be efficiently measured. It becomes possible.

  As described above, according to the present invention, the powder contained in a plurality of hoppers can be cut out and discharged by one vibrator, and it is necessary to transport the hopper or vibrate the entire hopper. Therefore, there is no need to increase the size of the moving carriage or vibrator even if the hopper is increased in size, so that the entire apparatus can be prevented from increasing in size and cost. Moreover, since only the discharge trough can be removed, the cleaning and washing can be easily and efficiently performed.

  1 to 6 show an embodiment of the present invention. Note that the following description of the preferred embodiment is merely an exemplification, and is not intended to limit the present invention, its application, or its use. The vibration type powder cutting device 1 of the present embodiment is shown in FIG. 2 on a base 2 assembled into a substantially rectangular parallelepiped frame shape by a plurality of frame materials having a square or L-shaped cross section, and an upper portion of the base 2. A plurality of (two in this embodiment) hoppers 3 arranged and fixed in a row as described above, discharge troughs 4 provided below the hopper discharge ports 3A of these hoppers 3, and these discharge troughs 4 is substantially composed of a carriage 5 that is movable in a moving direction (the left-right direction in FIG. 2) that is a direction in which the hoppers 3 are arranged further below. However, the arrangement of the plurality of hoppers 3 is not limited to that arranged in a straight line as shown in FIG. 2. For example, the hoppers 3 may be arranged in a circle or may be arranged so that the carriage 5 can move. It can arrange in the layout according to the place where the said cutting device is arrange | positioned, such as the L-shaped arrangement | sequence which combined the circumference.

  The hopper 3 in which the powder is stored has a cylindrical shape at the top and a conical shape whose diameter gradually decreases as it goes downward, and a lower end of the hopper 3 that has a smaller diameter than the top. The lower opening of the part is the hopper discharge port 3A. The hopper discharge port 3A is normally open, but can be closed by a lid (not shown) when the discharge trough 4 is cleaned. The plurality of hoppers 3 have the same shape and size in this embodiment. The hopper 3 may be a hopper having a rectangular parallelepiped shape at the upper part and a pyramid shape that gradually decreases in diameter as the lower part is directed downward, and a hopper discharge port having a rectangular cross section.

  In this embodiment, the discharge trough 4 has a rectangular tube shape with a rectangular cross section, and is placed horizontally so that its longitudinal direction is horizontal and perpendicular to the moving direction. It extends so as to protrude to the side portion (right side portion in FIG. 1). One end of the protruding discharge trough 4 in the longitudinal direction (the end on the right side in FIGS. 1, 3 and 5) is opened in a cylindrical shape to form a trough discharge port 4A, while the other end on the opposite side The end portion is a bottomed portion of the bottomed rectangular tube and is closed. In the present embodiment, the main body of the exhaust trough 4 that is horizontally placed in the shape of a bottomed square cylinder as described above is formed of a material that is not attracted to a magnet such as stainless steel.

  Further, an insertion hole having a sufficiently larger diameter than the cylinder formed by the lower end portion of the hopper 3 is opened on the other end side of the upper surface of the discharge trough 4, and the lower end portion of the hopper 3 is The hopper discharge port 3A is inserted into the discharge trough 4 through the insertion hole so as to face the bottom surface of the discharge trough 4 with a gap. Accordingly, the powder accommodated in the hopper 3 is held by being packed between the hopper discharge port 3A and the lower surface of the discharge trough 4 in a state where a part of the powder flows into the discharge trough 4. The A space between the periphery of the insertion hole on the upper surface of the discharge trough 4 and the lower outer peripheral surface on the lower end side of the hopper 3 is covered with a cylindrical flexible cover 6 that can be vertically expanded and contracted.

  Further, on the upper surface of the discharge trough 4, an elongated plate material having the same shape and the same size and extending in the moving direction at the other end in the longitudinal direction and an intermediate position between the insertion hole and the trough discharge port 4A on the upper surface. Are attached to each other, and both end portions in the above moving direction of these plate materials are projected from the upper surface of the discharge trough 4, and both end portions of these projecting plate materials are made to be supported portions 4B, respectively, in the vertical direction. A through hole 4 </ b> C penetrating through is formed. Note that the through hole 4C has a conical surface shape whose diameter gradually increases downward. Accordingly, in the present embodiment, a total of four supported portions 4B and through holes 4C are provided so as to be positioned at each corner of the rectangle in plan view.

  Such a discharge trough 4 is provided in the upper part of the base 2 and a shaft-like support member 7 extending downward is inserted into the through-hole 4C of the supported portion 4B of the discharge trough 4, It is supported so that it can be moved up and down as it is suspended from the base 2. As shown in FIGS. 4 and 6, the support member 7 has a cylindrical upper shaft portion 7A that is sufficiently smaller in diameter than the through hole 4C and is threaded on the outer periphery, and the upper shaft portion 7A and the through hole 4C. It is a bolt-shaped member having a lower end portion 7B having a large diameter, and is disposed at positions corresponding to the four through holes 4C of the discharge trough 4 in plan view.

  These support members 7 have the upper shaft portion 7A inserted from below into the through hole 4C of the supported portion 4B of the discharge trough 4, and the lower nut 8 is screwed into the screw of the upper shaft portion 7A. The upper nut 8A is inserted into a mounting hole penetrating the frame material of the base 2 positioned above the discharge trough 4 above the base 2 in the vertical direction, and the upper nut 8 is screwed into the pair of nuts 8 However, by sandwiching the frame material from above and below, it can be adjusted so that the vertical positions of the lower end portions 7B of the four support members 7 can be matched, and attached to the base 2. Here, the outer peripheral surface of the lower end portion 7B of the support member 7 is also formed into a conical surface shape that gradually increases in diameter downward, and the taper angle thereof is the conical surface formed by the inner peripheral surface of the through hole 4C of the supported portion 4B. Are equal.

  Accordingly, in the state where the discharge trough 4 in which the support member 7 is inserted through the through hole 4C is positioned at the lower end of the vertical movement by its own weight, the supported portion 4B comes into contact with the large-diameter lower end portion 7B of the support member 7. As a result, it is suspended from the base 2 as shown in the right side of FIG. 2 and FIGS. And in the state supported in this way, the cutting of the powder from the said discharge trough 4 is not performed, but the position of the discharge trough 4 at this time is made into the non-cutting position.

  On the other hand, as shown in the left side of FIG. 2 and FIGS. 5 and 6, when the discharge trough 4 is moved above the non-cutout position, the through hole 4 </ b> C of the supported portion 4 </ b> B of the discharge trough 4 and the support member The upper trough 7A is sufficiently spaced from the upper shaft portion 7A, and the spacing between the insertion hole of the discharge trough 4 and the lower end of the hopper 3 is also sufficient. The disengaged state is not engaged with the base 2 and the hopper 3. Therefore, in this state, the discharge trough 4 can be vibrated without interfering with the base 2 and the hopper 3, and the position of the discharge trough 4 at this time is set as a cutting position, and the powder is cut out.

  In the present embodiment, since the inner peripheral surface of the through hole 4C of the supported portion 4B and the outer peripheral surface of the lower end portion 7B of the support member 7 are conical surfaces, the discharge trough 4 is in the non-cutout position. It is positioned horizontally so that the centerlines of the conical surfaces are aligned with each other. In particular, according to the present embodiment, these conical surfaces have the same taper angle. Therefore, as shown in FIG. 4, the lower end portion 7B outer peripheral surface of the support member 7 and the inner peripheral surface of the through hole 7B are formed. Close contact and accurate positioning.

  In addition, the trough discharge port 4A of the discharge trough 4 positioned and supported in the horizontal direction at the non-cutout position is closed by the lid body 9. The lid body 9 has a rectangular plate shape that is slightly larger than the trough discharge port 4A that is opened in a rectangular shape, and the four sides of the rectangle have discharge troughs 4 when the lid body 9 blocks the trough discharge port 4A. A frame-like wall portion is formed to cover the peripheral edge portion of the trough discharge port 4A on the outer peripheral surface.

  Here, in the present embodiment, the lid body 9 is integrally attached to a rotating shaft 9A that is rotatably supported on the upper portion of the base 2, and the rotating shaft 9A serves as a trough discharge port 4A of the discharge trough 4. When the trolley 5 is placed so as to extend horizontally in the moving direction of the carriage 5 and the discharge trough 4 is in the non-cutout position, the lid 9 is suspended from the rotary shaft 9A as shown in FIG. Then, the trough discharge port 4A is urged toward the trough discharge port 4A by, for example, a torsion coil spring (not shown), and the trough discharge port 4A of the discharge trough 4 positioned as described above is closed.

  On the other hand, a lever 9B is integrally attached to the rotating shaft 9A so as to protrude obliquely upward on the one end side in the longitudinal direction of the discharge trough 4 in a state where the lid 9 closes the trough discharge port 4A. When the discharge trough 4 is arranged at the cut-out position, the lever 9B is pressed against the other end in the longitudinal direction of the discharge trough 4 against the urging force of the torsion coil spring or the like, as shown in FIG. The trough discharge port 4A is opened by rotating the lid 9 together with the rotating shaft 9A and flipping it up. The opening / closing means for opening and closing the lid body 9 is provided in the cart 5 in this embodiment.

  Here, the cart 5 includes a cart body 5A that can be moved by a driving means such as a motor on a pair of rails 2A laid so as to extend in the moving direction in parallel to each other at the bottom of the base 2. A vibrator 10 disposed below the hopper 3 on the cart body 5A and a measuring instrument 11 disposed so as to be positioned below the trough discharge port 4A of the discharge trough 4 opposite to the hopper 3 are provided. .

  Of these, a roller conveyor 12 is disposed above the measuring instrument 11, and the support base 12 </ b> A that supports the roller conveyor 12 has a gate shape as shown in FIG. 2 when viewed from the longitudinal direction of the discharge trough 4. A frame body 12B is provided up to a height that reaches the upper portion of the base 2 beyond the discharge trough 4, and a cylinder device 13 such as an air cylinder is provided on the upper portion of the frame body 12B as the opening / closing means. It has been.

  This cylinder device 13 is located at the center of the cart body 5A as shown in FIG. 2 in the moving direction of the cart 5, and is equal to the lever 9B of the lid 9 in the vertical direction as shown in FIG. The cylinder rod 13 </ b> A is disposed at a height and attached to the other end in the longitudinal direction of the discharge trough 4 so as to appear and disappear horizontally. The vibrator 10 is also arranged at the center of the cart body 5A in the moving direction of the cart 5 in the same manner as the cylinder device 13.

  When the vibrator 10 is positioned directly below the discharge trough 4 for performing the powder cutting operation, the cylinder device 13 is disposed at the position of the lever 9B of the lid body 9 of the discharge trough 4 in the moving direction. In this state, by projecting the cylinder rod 13A, the tip of the cylinder rod 13A pushes the lever 9B of the lid 9 of the discharge trough 4 as described above as shown in FIG. Then, the lid body 9 is opened.

  A measuring container 14 for storing the powder discharged from the discharge trough 4 is disposed on the roller conveyor 12, and the roller conveyor 12 can deliver the measuring container 14 to one end in the longitudinal direction of the discharge trough 4. It is said that. Further, the measuring instrument 11 can be moved up and down by the cylinder device 11A. When the powder is discharged from the discharge trough 4 into the measuring container 14 and accommodated, the measuring instrument 11 is inserted between the rollers constituting the roller conveyor 12. The measuring table of the measuring instrument 11 protrudes to lift the measuring container 14 and discharge is performed while weighing the discharged powder.

  Further, the vibrator 10 can also be lifted and lowered together with the table 10B by a cylinder device 10C interposed between the support base 10A disposed on the cart body 5A and the table 10B on which the vibrator 10 is placed. It is said that. A vibration isolating rubber 10D is further interposed between the table 10B and the vibrator 10. Further, the upper limit position of the rise of the vibrator 10 by the cylinder device 10C is that the bottom surface in the discharge trough 4 raised by engaging with the vibrator 10 is between the hopper discharge port 3A and the hopper discharge port 3A as will be described later. 3 is set at a position where the powder in 3 can flow into the discharge trough 4. In addition, although an electric cylinder, a hydraulic cylinder, an air cylinder, etc. can be employ | adopted for 10C of cylinder apparatuses, a table lifter etc. can be employ | adopted when a vibrator is large sized.

  Furthermore, an electromagnet 15 is provided on the upper portion of the vibrator 10, while a bottomed rectangular cylindrical body as described above is formed on the lower surface of the discharge trough 4 made of a material that is not adsorbed by a magnet such as stainless steel. Is attached to a suction plate 4D made of a metal material that can be attracted to a magnet such as an iron material at a position where the electromagnet 15 comes into contact with the vibrator 10 ascending. The electromagnet 15 is attached to the suction plate 4D. By being adsorbed and desorbed, the vibrator 10 can be engaged with and detached from the discharge trough 4. In the present embodiment, the suction plates 4D are arranged at two positions sandwiching the insertion hole in the longitudinal direction of the discharge trough 4, and the electromagnet 15 has two electromagnets 15 at substantially the same position in the longitudinal direction. In other words, the vibrator 10 can be engaged with and detached from the discharge trough 4 at a plurality of positions. However, in this embodiment, the vibrator 10 and the discharge trough 4 can be engaged and disengaged using the electromagnet 15 as described above. However, when the powder to be measured and discharged is a magnetic material, the magnetic force of the electromagnet 15 is the powder. In order to affect the cutting, a vacuum pad, a toggle clamp, or the like can be adopted as an engagement / disengagement means that does not require accurate positioning like an electromagnet.

  Next, the case where the powder contained in one of the plurality of hoppers 3 is cut out and discharged by the vibratory powder cutting device configured as described above will be described. First, the vibrator 10 and the weighing of the carriage 5 are measured. With the container 11 lowered, the cylinder rod 13A of the cylinder device 13 is also retracted, the weighing container 14 is carried onto the roller conveyor 12, and the cart 5 is discharged from the hopper 3 that performs powder cutting operation. The vibrator 10 is moved so as to be positioned immediately below the trough 4 and stopped. The movement of the carriage 5 is controlled by a limit switch 5B provided in the carriage body 5A.

  Next, the measuring device 11 is lifted by the cylinder device 11A to lift the measuring container 14, the weight of only the measuring container 14 is measured, the measured value is set to 0, and taring is performed. Further, when the vibrator 10 is positioned directly below the discharge trough 4 as described above, the cylinder device 13 is disposed at the position of the lever 9B of the lid body 9 of the discharge trough 4 in the moving direction. , The lever 9B is pressed toward the other end in the longitudinal direction, the lid body 9 is rotated around the rotation shaft 9B, and the trough discharge port 4A is opened.

  When the trough discharge port 4A is opened in this way, the electromagnet 15 above the vibrator 10 is energized to generate a magnetic force, the vibrator 10 is raised by the cylinder device 10C, and the electromagnet 15 attracts the suction plate 4D on the lower surface of the discharge trough 4. And the vibrator 10 and the discharge trough 4 are engaged. When the vibrator 10 is further lifted together with the discharge trough 4, the discharge trough 4 is lifted upward from the non-cutting position at the lower end of the vertical movement and arranged at the cutting position. As described above, the base 2 and the hopper 3 is not engaged.

  Therefore, the vibrator 10 is disposed at the upper limit position, and the vibrator 10 is placed in a state where the powder can flow between the hopper discharge port 3A and the bottom surface of the discharge trough 4 in the cut-out position. By operating and applying vibration to the discharge trough 4, a part of the powder previously flowing into the discharge trough 4 is discharged into the measuring container 14 from the trough discharge port 4 </ b> A. The body is cut out and flows into the discharge trough 4, is sequentially discharged from the trough discharge port 4 </ b> A, and is stored in the measuring container 14.

  Thus, the powder in the hopper 3 is cut out into the discharge trough 4 and discharged from the trough discharge port 4A to the measuring container 14, and when the powder of a predetermined weight is accommodated in the measuring container 14, the vibrator 10 is stopped. Then, the discharge of the powder is finished. At this time, the weight of the powder discharged to the measuring container 14 is sequentially weighed, and when the measured value approaches the target value, the amplitude of vibration applied from the vibrator 10 to the discharge trough 4 is reduced stepwise. It is desirable to control so that the powder having the weight exactly as the target value is accommodated in the measuring container 14.

  Next, when the energization of the electromagnet 15 is stopped and the vibrator 10 and the discharge trough 4 are disengaged, and the vibrator 10 and the measuring instrument 11 are lowered by the cylinder devices 10C and 11A, the discharge trough 4 moves up and down. When the lower end of the movement is lowered to the non-cutting position, the supported portion 4B comes into contact with the lower end portion 7B of the support member 7 and is positioned, so that a part of the powder in the hopper 3 again becomes the bottom surface in the discharge trough 4 and the hopper It is held tightly between the outlet 3A.

  Therefore, by retracting the cylinder rod 13A of the cylinder device 13 as the opening / closing means of the lid 9, the lid 9 rotates to close the trough discharge port 4A of the discharge trough 4, and the hopper provided with the discharge trough 4 The operation for cutting out powder from 3 is completed. Subsequently, when the powder stored in the other hopper 3 is discharged to the same measuring container 14 and weighed, the above operation is repeated, and then the measuring container 14 is discharged from the roller conveyor 12.

  As described above, in the vibratory powder cutting device having the above-described configuration, in order to cut out the powder from the plurality of hoppers 3, the hopper 3 is not transported to the position of the vibrator 10, but the cart provided with the vibrator 10. 5 is moved to the position of the hopper 3, and it is only necessary to vibrate the discharge trough 4 provided in each hopper 3 instead of giving vibration to the entire hopper 3. For this reason, even if the amount of powder accommodated in the hopper 3 is increased and the hopper 3 is enlarged, the moving means such as the carriage 5 for moving the vibrator 10 is not enlarged. Since it is not necessary to increase the size of the device itself, it is possible to avoid an increase in size and cost of the entire apparatus.

  Further, while the hopper 3 is fixed to the upper portion of the base 2, the discharge trough 4 is movable up and down and is separated from the hopper 3, so that the hopper discharge port 3A as described above. When the support member 7 is extracted from the frame material of the base 2 with the lid closed, the discharge trough 4 alone can be removed. For this reason, for example, even when only the discharge trough 4 is cleaned or replaced, there is no need to extract all the stored powder and wash and replace the entire hopper 3, thereby improving maintenance. Can do.

  Further, in the present embodiment, the discharge trough 4 that can be moved up and down in this manner is configured such that the supported portion 4B comes into contact with the lower end portion 7B of the support member 7 in the non-cutting position at the lower end of the vertical movement. While being supported so as to be suspended from 2, when lifted to a cutout position higher than the non-cutout position, between the upper shaft portion 7A of the support member 7 and the through hole 4C of the supported portion 4B. At intervals, the base 2 and the hopper 3 are disengaged from each other, and vibration is applied to the cutting position so that the powder is cut out and discharged.

  However, the discharge trough 4 is movable up and down with respect to the base 2 and the hopper 3 as described above, and is suspended and supported at the non-cutting position on the lower end side of the vertical movement, while the discharge trough 4 is non-cut at the cutting position above this. In order to enter the engaged state, for example, it may be possible to elastically suspend and support the base 2 from a coil spring or the like, but in such a case, the non-cutting position on the lower end side of the vertical movement is not stable. While the powder may continue to flow into the discharge trough 4 from the hopper 3 and leak, the discharge trough 4 in the non-cutting position according to the present embodiment by adopting the above-described configuration. Can be reliably and stably supported.

  In addition, in the present embodiment, the outer peripheral surface of the lower end portion 7B of the support member 7 and the inner peripheral surface of the through hole 4C formed in the supported portion 4B of the discharge trough 4 are conical surface shapes that gradually increase in diameter as they go downward. When the discharge trough 4 is in the non-cutting position, the center lines of these conical surfaces are made to coincide with each other so that the discharge trough 4 can be positioned in the horizontal direction and supported more stably. . In particular, in the present embodiment, these conical surfaces have the same taper angle, and the outer peripheral surface of the lower end 7B and the inner peripheral surface of the through hole 4C are in close contact with each other, so that it is even more stable.

  Further, when the discharge trough 4 is unstable at the non-cutout position as in the case where the discharge trough 4 is suspended by the coil spring or the like, the trough discharge port 4A is blocked by the lid 9 at the non-cutout position. Even if it is going to be, the position of the trough discharge port 4A is not stable, so the lid body 9 and its opening / closing means must be provided on the discharge trough 4 side. Therefore, in such a case, opening / closing means is required for each discharge trough 4, and the opening / closing means is damaged by vibration applied to the discharge trough 4, or the lid body 9 is closed during discharge of the powder. There is a possibility that the powder cannot be discharged from the trough discharge port 4A.

  On the other hand, in the present embodiment, the lid 9 is moved to the base 2 side in combination with the discharge trough 4 being stably positioned also in the horizontal direction particularly at the non-cutout position as described above. It can be provided and the influence of the vibration given to the discharge trough 4 can be prevented. The lid body 9 is urged toward the trough discharge port 4A when the discharge trough 4 is in the non-cutting position, so that the trough discharge port 4A can be reliably closed and the powder cutting operation can be performed. When performing, since it is opened by the opening / closing means provided in the cart 5 moved to the position of the hopper 3 for performing this cutting operation, the opening / closing means is one for the discharge trough 4 provided in the plurality of hoppers 3. Is efficient.

  On the other hand, in this embodiment, while the electromagnet 15 is attached to the upper part of the vibrator 10, the discharge trough 4 is formed of a material that is not adsorbed by a magnet such as stainless steel, and is formed on the lower surface of the main body. A suction plate 4D formed of a metal material such as an iron material to be attracted to the magnet is attached at a position where the electromagnet 15 is substantially in contact with the vibrator 10 when the vibrator 10 is raised. By generating a magnetic force and attracting the suction plate 4D, the exhaust trough 4 and the vibrator 10 are engaged with each other so that vibration from the vibrator 10 is applied to the exhaust trough 4 and energization is stopped. The exhaust trough 4 and the vibrator 10 can be engaged and disengaged in such a manner that they are uncoupled and detached.

  However, although it is possible to disengage the discharge trough 4 and the vibrator 10 by this point, for example, by mechanical engagement / disengagement means, in that case, the carriage 5 is moved accurately to engage the vibrator 10 side. After the detaching means is positioned immediately below the engaging / disengaging means on the discharge trough 4 side, the vibrator 10 must be raised to engage with the discharge trough 4. On the other hand, according to the present embodiment, the electromagnet 15 can be engaged if it is located substantially below the lower surface of the discharge trough 4, so that it does not require so strict control to move the carriage 5. It is possible to reliably apply vibration to the discharge trough 4.

  In the present embodiment, the main body of the discharge trough 4 is formed of a material that is not attracted to the magnet, and a suction plate 4D made of a metal material such as an iron material that is attracted to the magnet is attached to a part of the body. However, the entire discharge trough 4 may be formed of a metal material such as an iron material attracted to the magnet.

  Furthermore, the carriage 5 is moved to the position of the hopper 3 where the powder cutting operation is performed among the plurality of hoppers 3, and is discharged by the cylinder device 13 as the opening / closing means provided in the carriage 5. 4 lid 9 is opened and closed, and the discharge trough 4 is vibrated by the vibrator 10, and the powder is discharged from the trough discharge port 4A. Therefore, the weighing container 14 that stores the powder discharged from the trough discharge port 4A and the measuring instrument 11 that measures the weight of the powder stored in the weighing container 14 are also the cart 5 as in the present embodiment. For example, the weighing device 11 and the weighing container 14 are more efficient than the case where the weighing device 11 and the weighing container 14 are provided for each hopper 3.

  Furthermore, in this embodiment, the roller conveyor 12 is arrange | positioned on the measuring instrument 11 with which this trolley | bogie 5 was equipped, and in the case of measurement, the measuring instrument 11 raises by the cylinder apparatus 11A, and the measuring platform becomes a roller. While protruding from between the rollers of the conveyor 12 and weighing the weight by lifting the weighing container 14, the weighing device 11 is lowered by the cylinder device 11A after the powder of the target weight is discharged to the weighing container 14. Thus, the measuring container 14 containing the powder is placed on the roller conveyor 12 and can be dispensed.

  Therefore, according to the present embodiment, if a conveyor for receiving the weighing container 14 that can be connected to the roller conveyor 12 and is thus dispensed is disposed at one place in the movement range of the carriage 5, eventually, Even if the powder is cut out from the hopper 3, the measuring container 12 is moved together with the roller conveyor 12 by moving one carriage 5, and discharged to the conveyor, so that it can be smoothly conveyed to the next step. So it is more efficient.
