Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a powder or other powder or granular material dividing device.

 [Prior Art] In general, various powder packaging machines have been put into practical use, in which an arbitrary amount of powder (granular material) is divided into a predetermined number of packages such as 21 packets or 42 packets for packaging. There is.

 In order to divide a powder into a predetermined number of divided packages with this type of powder packaging machine, conventionally, the entire circumference is divided into the same number as the predetermined number of divided packages such as 21 or 42, and an annular divided mass body is formed above the ring divided mass body. A turntable with an annular groove having the same diameter as the divided mass and a V-shaped cross section is installed. While rotating the turntable in one direction, the powder is introduced into the V-shaped groove and distributed over the entire circumference. Open the bottom of the groove and drop it into all the divided masses, or do not use a turntable with a V-shaped groove and make a normal or reverse ring divided mass body with a maximum of 90 While rotating, the powder is directly put into a predetermined number (eg 21 or 42) of divided masses and distributed.

[Problems to be solved by the invention] However, in the former case, the turntable having the V-shaped groove and the ring-shaped divided mass body must be vertically arranged, and all the divided masses formed in the ring-shaped divided mass body are required. The powder can be divided into the same number as the above, and the latter must change the switching position of forward and reverse rotation of the annular divided mass body for the distribution according to the required division number of the powder. In addition, since the ring-shaped divided mass bodies stop momentarily at the switching position, the distribution amount of the powder continuously fed from the appropriate powder feeder differs between the divided masses at both ends and the other divided masses. Therefore, there was a problem that the amount of powder divided was likely to be uneven between the divided masses at both ends.

 The present invention solves the problems of the above-mentioned conventional ones, and the number of divisions of powder and granules can be arbitrarily set in a wide range, and even if the number of divisions is large or small, it should be divided. It is an object of the present invention to provide a powder / granule dividing device capable of substantially evenly dividing.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention has a table having an annular mounting surface, and the tip is arranged in proximity to the mounting surface, and the relative rotation with the table. With the above, the granular material feeder that transfers the granular material along the mounting surface, and the granular material transferred from the granular material feeder onto the mounting surface is cut out from the table by any angle. It is equipped with means.

[Operation] By adopting the above means in this invention, the powder or granular material transferred from the powder or granular material feeder onto the annular mounting surface of the table is not limited to the cutting angle of the cutting member. The angle is cut out for each angle corresponding to the desired number of divisions.

[Embodiment] An embodiment of the present invention shown in the drawings will be described below.

 1 to 3 show an embodiment of the present invention, 1 is a machine frame in which a hopper 2 is arranged in the center of the upper part, and an appropriate packaging device 3 is arranged in the lower part of the hopper 2, 4 and 4 are hoppers 2 The turntables (powder / granular table) are rotatably supported on the machine frame 1 on both sides of the turntable 4, and the turntables 4 and 4 are formed in an annular shape with a predetermined width in the radial direction. Gears 6, 6 are provided below a thin plate having various mounting surfaces 5, 5.

 The motors 8 and 8 equipped with the gears 7 and 7 meshing with the gears 6 and 6 can control the rotation speed and the rotation angle, and the motors 8 and 8 can be controlled according to the mass of the powder or granular material to be handled. The rotation speed, that is, the speed selection members 9 and 9 for arbitrarily selecting the rotation speeds of the turntables 4 and 4, and the rotation angles of the motors 8 and 8, that is, the turntables 4 and 4 depending on the number of divided powder particles. An angle selection member 10, 10 for arbitrarily selecting a rotation angle is provided, so that the turntables 4, 4 are rotated in one direction at a selected speed by driving the motors 8, 8 and the selected angle is selected. It is sent intermittently by the minute.

 Reference numerals 11a and 11b are electromagnetic feeders (powder feeders) provided on the machine casing 1 corresponding to the respective turntables 4. The electromagnetic feeders 11a and 11b are hoppers 12a and 12b and a vibrating gutter 13a, respectively. , 13b, the tips of the vibrating gutters 13a, 13b are arranged at a minute height from the mounting surface 5 in the vicinity of the radial center of the mounting surface 5, so that the vibrating gutters 13a, 11b are actuated by the operation of the electromagnetic feeders 11a, 11b. The powder or granular material supplied from the front end of 13b to the turntable 4 is designed to be placed rather than being dropped near the radial center of the mounting surface 5.

 Reference numerals 14 and 14 denote powder and granular material cutting devices provided on the machine frame 1 in the vicinity of the hopper 2 respectively corresponding to the turntables 4 and 4, and the cutting devices 14 and 14 are provided with rubber parts at the bottom. Movable members 16 and 16 having substantially J-shaped cutting members 15 and 15 made of a flexible material such as, and both turning tables while the cutting members 15 and 15 are in contact with the mounting surfaces 5 and 5. Each of the cutting members 15 is provided with a driving member 17, 17 such as a reversible motor that horizontally reciprocates the movable members 16, 16 along a line that connects the centers of 4, 4 directly above the hopper 2. The protruding angle r (see FIG. 3) is formed equal to the angle obtained by dividing the entire circumference of the mounting surface 5 into 42.

 Therefore, when the number of divisions of the powder particles distributed annularly on the mounting surfaces 5 and 5 is equal to 42, the movable bodies 16 and 16 move forward from the retracted position with the turntables 4 and 4 stopped. Along with this, the cutting members 15 and 15 cut out the powder particles corresponding to the cutting angle toward the hopper 2 and put them into the hopper 2.

 When the number of divisions of the powder or granular material is less than 42, the turntables 4 and 4 are first rotated by an angle while the movable bodies 16 and 16 are in the retracted position, and the powders of an angle corresponding to the number of divisions. After the particles are gathered within the cutting angle of the cutting members 15 and 15, the turntables 4 and 4 are stopped and the cutting members 15 and 15 are cut by the movement of the movable bodies 16 and 16. The powder or granular material that has been restrained within the projecting angle is cut out toward the hopper 2 and put into the hopper 2.

 Further, when the number of divided powder particles is more than 42, as shown in FIG. 3, the turntables 4, 4 are turned in the state where the movable bodies 16, 16 are in the retracted position (see FIG. 3 (a)). Turns once in the opposite direction to make a blank part for the predetermined angle within the cutting angle r of the cutting members 15 and 15 (see FIG. 3 (b)), and then the turntables 4 and 4 stop. Then, as the movable bodies 16 and 16 move forward, the cutting members 15 and 15 hopper the powder particles within the cutting angle r 1 (that is, an angle smaller than the cutting angle r by the blank portion angle). It is cut out toward 2 (see FIG. 3 (c)) and put into the hopper 2.

 Then, in any of the above cases, after the first division is completed, the turntables 4, 4 are intermittently fed at a pitch corresponding to the number of divisions, and each time the cutting members 15, 15 make one package of granular material. The rotation angle of the turntables 4 and 4 described above is controlled by the angle selection members 10 and 10.

 The reason why the cutting angle r of each cutting member 15 is formed so as to correspond to 42 divisions of the entire circumference of the mounting surface 5 is that the number of divided doses of the powder prescribed to the outpatient is 3 times a day for 21 days. There are various types, such as 42 packets for 14 days 3 times a day, 90 packets for 30 days 3 times a day. Of these, 42 packets are relatively common, and 42 packets are standard. This is because it is convenient to accommodate various numbers of divided packages, since 21 packages are half that and 90 packages are about twice that.

 The cutting devices 14, 14 rotate the turntables 4, 4 in one direction and actuate the electromagnetic feeders 11a, 11b to distribute the powder particles on the placing surfaces 5, 5 in a ring shape. At this time, in order to separate the cutting members 15 and 15 from the mounting surfaces 5 and 5, the movable bodies 16 and 16 are retreated from the retracted position to a rearward (radially inward) retracted position, or the movable bodies 16 and 16 are retracted. 16 is lifted from the retracted position or is provided with a separating means by other suitable method.

 Reference numeral 18 denotes a dust collecting device provided with dust collecting nozzles 19 and 19 which are located close to the turntables 4 and 4.

 Next, the operation of the above-mentioned dividing device will be described. Since the operations of distributing and dividing the powder particles to both turntables 4 and 4 are similar to each other, only one will be described and the other will be omitted. I will.

 First, the cutting member 15 is separated from the mounting surface 5, the powder particles are put into the hopper 12a (or 12b), and the turntable 4 is rotated in one direction while the electromagnetic feeder 11a (or 11b) is rotated. ) Is activated.

 At this time, the rotation speed of the turntable 4 is determined by the centrifugal force received by the turntable 4 from the tip of the vibrating gutter 13a transferred from the tip of the vibrating gutter 13a to the mounting surface 5 from the turntable 4 according to its mass. Therefore, the velocity selection member 9 selects the moment of inertia according to the mass of the powder or granular material so as not to scatter from the mounting surface 5.

 Then, the granular material thrown into the hopper 12a is transferred from the tip of the vibrating gutter 13a to the vicinity of the center of the mounting surface 5 in the radial direction by the operation of the electromagnetic feeder 11a, and the turn table 4 rotates in one direction. It will be evenly distributed in a ring over the entire circumference.

 When the distribution of the powder and granules is completed, the operation of the electromagnetic feeder 11a is stopped and the rotation of the turntable 4 is once stopped.

 Next, the cutting member 15 is set to the retracted position in contact with the mounting surface 5, and when the number of divided particles is 42, the moving member 16 is simply moved forward and the cutting member 15 The powder particles for the cutting angle (that is, for 42 divisions) are cut toward the hopper 2 and put into the hopper 2.

 When the number of divided powder particles is less than 42, first, the turntable 4 is rotated by an angle, and the powder particles corresponding to the divided number are gathered within the cutting angle of the cutting member 15. After that, when the turntable 4 is stopped and the movable body 16 is moved forward, the cutting member 15 cuts out the powder or granular material that has been restrained within the cutting angle toward the hopper 2 and puts it into the hopper 2.

 Further, when the number of divided powder particles is more than 42, the turntable 4 is once rotated in the opposite direction to form a blank portion for the predetermined angle within the cutting angle r of the cutting member 15. When the turntable 4 is stopped and the movable body 16 is advanced, the cutting member 15 hoppers the powder particles within the cutting angle r (that is, the angle smaller than the cutting angle r by the blank portion angle). Cut out toward 2, and put in the hopper 2.

 In any case, the powder or granular material put into the hopper 2 is divided into one packet by the operation of the packaging device 3.

 After that, the movable member 16 is retracted to the retracted position, and the movable member 16 is advanced and retracted each time while the turntable 4 is intermittently fed at a pitch corresponding to the number of divisions. 1 pack is cut out and put into the hopper 2, and the powder and granules put into the hopper 2 are divided into 1 pack by the operation of the packaging device 3.

 If the number of divided particles is more than 42, it means that the last particles are gathered only by the angle at which the blank part was created first. In this case, turntable 4 It may be corrected by reducing the feed pitch for the last 2-3 packages of.

 If different powders are put into the hoppers 12a and 12b and used at the same time, both powders can be divided and packaged together.

 Further, since the above-mentioned dividing device is equipped with two sets of the turntable 4, the electromagnetic feeders 11a and 11b, the cutting device 14, etc., the distribution work of the granular material on one turntable 4 and the turntable on the other side are performed. The division work of the granular material in step 4 can be performed simultaneously in parallel, and therefore, the division operation of the sawed granular material can be started immediately after the completion of the division operation of the preceding granular material, As a result, when performing distribution and division work of multiple types of powder and granules, the time required for the distribution work in the middle can be apparently omitted, and the required distribution and division work can be completed in the shortest time overall. It is a thing.

 Although two turntables 4 and 4 are provided in the above embodiment, the present invention is not limited to this, and two electromagnetic feeders 11a and 11b are provided on each turntable 4, but this is not a limitation. In addition, the tips of the vibrating gutters 13a and 13b are radially out of phase with each other in the vicinity of the radial center of the mounting surface 5, so that the powder particles and the vibrating gutter 13b transferred from the vibrating gutter 13a are not moved. The transferred powder and granules may be concentric with each other in the vicinity of the center in the radial direction of the mounting surface 5. Furthermore, the selection operation of the speed selection members 9 and 9 is required for the powder and granules to be handled. You may just enter the data of, and let it be automatically selected by the computer, for example.

 Although the turntables 4 are rotated in the above embodiment, the electromagnetic feeders 11a and 11b may be rotated around the center of the mounting surface 5 of the appropriate table. 5 is not necessarily flat as long as it has an annular shape, and the electromagnetic feeders 11a and 11b may be arranged not only on the radially inner side of the annular mounting surface 5 but also on the radially outer side, An appropriate powder feeder other than the electromagnetic feeder may be used.

 Further, in the above-mentioned embodiment, each cutting device 14 is configured to move in the horizontal plane while the cutting member 15 is in contact with the mounting surface 5 by the horizontal reciprocating movement of the movable body 16 to cut out the powder or granular material. However, the cutting angle r of each cutting member 15 is equal to the angle obtained by dividing the entire circumference of the mounting surface 5 into 42, but the present invention is not limited to this. Regardless of the size of the cutting angle r of each cutting member 15, it is possible to divide the cutting member 15 into a large number of divisions of 90 minutes or more. It goes without saying that is possible.

[Advantages of the Invention] Since the present invention is configured as described above, the granular material transferred from the granular material feeder to the annular mounting surface of the table is not limited to the cutting angle of the cutting member. In addition, since it is possible to cut out and divide by an angle corresponding to the desired number of divisions, a turntable having a V-shaped groove unlike the conventional one is unnecessary, and since no annular division mass body is used, the powder is not used. It has an excellent effect that the number of particles can be arbitrarily set in a wide range and that the particles to be divided can be divided substantially evenly regardless of the number of divisions. Is to have.
