Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a method and apparatus for selectively dividing an arbitrary amount of powder or granular material into a required number of equal parts.

Various methods have already been devised and put to practical use for dividing and packaging pharmaceuticals, seasonings, sweeteners, and other substances in the form of powder or granules into required amounts.

Conventionally, when packaging powder or granules into small portions, there are two methods: one is to divide the material quantitatively and then the other is to weigh it using weights and then package it. In terms of workability, the former method of quantitatively measuring is convenient for packaging a large amount of powder and granular material, and this method is used because the equipment can be simplified.

In addition, in order to divide the amount of packaging by measuring the weight using the latter method, the structure becomes complicated and sophisticated, which naturally increases the price, and since it is a precision product, skill is required for adjustment and other handling. This is not common.

Therefore, when dividing the required amount of powder or granules into equal parts as described above (well, the remaining part of the powder or granules poured into a previously prepared measuring container with something like a scraping board) Since it is necessary to scrape off the excess by scraping off the powder and granules on a measuring container, there is naturally a loss in the powder and granules that are being handled. It is difficult to perform the actions uniformly.

In addition, if the amount of powder to be supplied at one time is different, it is inconvenient that the measuring container must be replaced with a corresponding one. There are many things that need to be improved, such as the ability to only do split weighing.

The present invention solves many of these problems, and by a method different from the conventional method, the pivot portion of the upper part of the column and the vertically movable support portion are provided at predetermined intervals on a movable body that can move freely. are connected by an inclined guide rod of an appropriate length, and when the movable body is in the traverse starting position, a vertical movable part placed adjacent to the movable support part of the inclined guide rod has a cylinder-type measuring rod installed upright. The capacity of the divided total amount of powder and granular material to be distributed is set by indirectly or directly connecting to the ram forming the movable bottom of the container, and by moving the movable support part of the inclined guide rod up and down to move the ram in the measuring container up and down in conjunction. Then, divide the vertical line passing through the pivot point of the inclined guide rod at the starting end position and the perpendicular line passing through the vertical movable part into an arbitrary number of divisions at equal intervals, and move the inclined guide rod as set above. The body is intermittently moved from the starting position to a perpendicular position passing through the vertical movable part, and the ram is raised by the intermittent lateral movement valve along the inclined guide rod via the vertical movable part, and in conjunction therewith, The purpose is to enable the required amount of powder or granule to be equally divided into arbitrarily set numbers by scraping the powder or granule extruded onto the measuring container intermittently.

In the present invention, in order to smoothly carry out the above-mentioned intended operations, a measuring moving body is provided at a suitable location on the aircraft body, and a supporting column of an appropriate height is erected at one end of the measuring moving body. At the same time, a positioning rod of a required length is provided at an appropriate distance from the column and moves up and down in the vertical direction parallel to the column perpendicular. The upper end of the position setting rod (a tilted guide rod is provided with a loose support), and the gear provided on the position setting rod is engaged with a rotating gear on the control shaft that can maintain a fixed position, and a lifting force is constantly applied. The measurement movable body is always applied with a lateral movement force in the measurement movement direction, and when the measurement movable body is at the starting position, there is a vertical displacement at a position adjacent to the position setting lever lifting part. A sensor is provided, and electrically connected via the sensor to a drive machine that drives a ram with a movable bottom up and down in a cylindrical measuring container of a desired diameter vertically arranged at a suitable location on the machine body, and the measuring moving body is A feed consisting of a control section and a return drive section that move intermittently at an arbitrarily set number at equal intervals between a perpendicular line passing through the pivot point of the inclined guide rod at the starting position and a perpendicular line passing through the movable intersection where the sensor and the inclined guide rod touch. In conjunction with the mechanism, a scraping plate mechanism linked to intermittent feeding is attached to the upper opening of the measuring container to constitute a quantitative dividing device.

゛In addition, as another means for carrying out the present invention, a measuring moving body equipped with an inclined guide rod similar to that described above may be divided intermittently in a predetermined section according to an arbitrarily set number of divisions, only during outbound movement, etc. A linear gear is provided on the position setting rod, which is connected to a drive control feed mechanism that moves at intervals, and is used to raise and lower the ram forming the movable bottom of the cylindrical measuring container to set the divided total capacity. The rotating gear that meshes with this gear is driven by a reduction motor, and a device is used in which the operations of each part are interlocked by an electrical control mechanism.

As a means of directly operating the inclined guide rod according to the present invention to set the total capacity of the measuring container, a straight line such as a rack gear or a pin gear is used as a position setting rod that freely supports the tip of the inclined guide rod and operates the vertical movement. A pinion or chain wheel that meshes with a linear gear such as a rack gear or a pin gear is driven by a pulse motor, a step motor, or a clutch or a morph with a brake (a morph with a clutch or brake is used to drive the vertical movement by finely rotating one rotation). 1. Rub to ensure accuracy.

In addition to such gear engagement, a system may also be adopted in which a screw shaft is used to move up and down by screwing.

Of course, if the volume is clarified in advance, it is also possible to set it manually.

In addition to sensors such as photoelectric switches, a guide made of a rotating roller may be placed in contact with the guide rod, or the guide may sandwich the inclined guide rod from above and below, and the pair of guides may be The mounting piece is rotatably supported on the support member I so that the pivot point coincides with the intersection of the center line of the inclined guide rod and the line connecting the centers of the pair of guide elements.

(The means for connecting the guide mounting piece operated by the inclined guide rod and the ram forming the movable bottom of the weighing container include a method of directly connecting the two with a connecting piece, etc.) The ram is electrically detected, and the ram is raised and lowered using separate power based on the detection signal, or the displacement of a predetermined part of the inclined guide rod is detected using a photoelectric detector, etc., and the ram drive means is activated using the detection signal. A sensor configured to at least move up and down may be employed.

In addition, regarding the setting of the intermittent feed interval of the measuring moving body, several division numbers are set that can selectively define the total moving distance.
A means for electrically controlling the intermittent drive body according to this set value, a means for performing intermittent feeding by combining an equally divided mechanical movement prevention mechanism and an electrical control mechanism, and other means for controlling the amount of movement as necessary. By combining various means and drive methods, it is sufficient to adopt the method that is most convenient for handling.

According to the dividing method of the present invention, the total amount of powder to be processed is set by moving the movable bottom up and down so that the volume from the top opening end of the measuring container to the bottom surface becomes the required amount, and after setting the volume, measurement is performed. The guide element is pushed upward along the set inclined guide rod by moving the pivot point side of the inclined guide rod toward the movable intersection side according to the number of divisions set selectively in a predetermined section of the moving body. - tanθ×movement length
is the inner diameter of the weighing container, l is the displacement dimension of one division, and is extruded from the weighing container, scraped by a scraping plate, and sent to the packaging container. Then, by changing the inclination angle θ and the length of one movement of the inclined guide rod, that is, the number of divisions, it is possible to divide the powder into any desired amount for packaging, etc., and the division amount can be selected from a wide variety. It has become extremely easy to divide into equal parts accurately, so it is very effective when used in packaging machines used to package drugs at hospital pharmacies, etc., and in other routine applications. This is a method that can be adopted and operated effectively in industries where small quantities of powder and granular materials are handled and divided, other than in factories where powder materials are divided and packaged.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

What is shown in FIG. 1 is a schematic diagram of a specific example of an apparatus for carrying out the method of the present invention, in which both ends are supported by a pair of support pieces 2, 2 that protrude laterally at a required interval from one side of a fuselage 1. Parallel guide rails 3, 3 are provided vertically and at appropriate intervals for support, and the measuring moving body 10 is provided so as to be able to move freely along the guide rails 393.

The measurement movable body 10 is suitably shaped into a frame or a box, with a relatively long support 11 erected at the top of one longitudinal end, and a base end of an inclined guide rod 12 on the side surface of the upper end. The installation is configured such that the movement of the guide is not hindered, and is pivoted via a metal fitting 13. The positioning rod 14 is slidably supported via a swingable slide bearing 16 at the tip of the positioning rod 14, which is driven to move vertically up and down by being driven up and down on the side of the measuring object. The lower end of a tension spring 19, which is vertically movably supported by a slide bearing 17.17 attached to a bracket 18.18 biased by A rack gear 15 is installed on one side of the rod 14.
The pinion gear 20 attached to the movable body is rotatably attached to the shaft 21 and meshes with the rack gear 15, and the pinion shaft 21 is equipped with a simple electromagnetic clutch mechanism (not shown). is attached so that it is always in a stopped state, and when a signal is given, the flake comes off and the pinion shaft can rotate.

The measuring movable body 10, which is equipped with each of these mechanisms, is connected to a drive mechanism, such as a small-pitch chino 22, by a connecting fitting 23, and a winding suspended over a required section at the lower part of the body The winding of 22 is carried out by connecting a drive motor or a drive mechanism that drives the measurement movable body 10 only in the direction of the return process (arrow A) to one of the shafts of the chain wheels 24 and 24' via a clutch. A tension spring 25 is stretched between a proper position of the body 10 and one of the supporting pieces 2 or the machine body 1.

The intermittent feed amount of this measuring moving body 10 is such that the moving distance from position a to the position in FIG. 3 is the total moving length.
This section is selected at desired intervals and divided into equal parts, and the -section length L' is set as the intermittent feed length. Therefore, the arbitrary number of sections nXI,'=I, A mechanism for selecting the E
In order to perform this intermittent feeding operation, a numerical selection and distribution mechanism is used, in which the required number of divisions is set up in advance for the total length L, and a clutch that provides a stopping function is connected to one chain wheel of the drive chain wheel 22, for example. Connect the electromagnetic operation mechanism and operate the moving body 1 electrically to apply a tension spring force of 25 over the required area.
0 repeats the operation of running and stopping intermittently.

Of course, as for the mechanism for selecting the category, in addition to the electric control system, various systems such as a mechanical system or a combination of a mechanical system and an electric switch can be adopted.

For the inclined guide rod 12, the guide element 4 is always in contact with the upper surface of the guide rod 12, and the length in the vertical direction drilled in the fuselage 1 is adjusted as shown in FIGS. 1 and 2. The guide fitting that penetrates through the hole 5 to the opposite side is attached to the piece 6 with a support pin 6', and the piece 6 is attached to the body 1 by appropriate means at a position opposite to the side. A movable bottom that can be inserted into the vertically arranged cylinder-shaped measuring container 30 is connected to the lower end of the rod 33 of the ram 32 whose top surface forms a screw shaft 7 driven by a separate electric motor (not shown). The ram 32 slides within the cylinder body 31 of the measuring container 30 and is displaced upward by moving the guide element 4 up and down by a corresponding amount (the amount of displacement of the guide element 4).

The measuring container 30 is arranged so that its axis is perpendicular to the installed state, has the required inner diameter and length, and has a thin spiral air vent groove 3 on the outer periphery of the ram 32.
4 is carved into the air supply hole 3 so that compressed air is supplied to and discharged from the lower end of the rod 33 to this groove 34.
5 and an exhaust hole 36 are connected, and the ram 32 can move and slide smoothly while being supplied with pressurized air in the groove 34.

Further, a surface plate 37 is attached to the upper end of the main body 31 of the measuring container 30, and in conjunction with the intermittent feeding of the measuring moving body 10, the moving body 10 moves one pitch until moving to the next operation. In between, a scraping plate 38 is used to carry out the feeding operation (
An intermittent drive mechanism 39 is provided.

40 is a chute, and 50 is a packaging bag.

. Next, to explain the present invention in detail using the apparatus configured as described above, first, in order to set the total divided amount of the granular material A to be processed, the electromagnetic brake is actuated to free the shaft 21 of the pinion gear 20. Then, if the electric motor for driving the ram 320 of the measuring container 30 is started and the volume inside the measuring container 30 is set, the guide piece 6 will be moved in the same way.
The pinion gear 20 is in a free state according to its movement.
The position setting rod 14 with the engaged rack gear 15 is raised by the force of the tension spring 19, or vice versa, is pushed down via the guide element 4, and the inclination angle of the inclined guide rod 12 is set.

Note that during this positioning, the support 11 of the measuring moving body 10
This is done with the holder positioned at the extreme end (on the right side in the figure) as shown by the solid line in FIG.

Once the measuring volume has been set in this way, the required number of divisions is selected in advance using the numerical selection and distribution mechanism attached to the device, and the powder and granular material to be processed is placed in the measuring container 30 at a high density. If the drive motor of the weighing container ram 32 is operated, the guide element 4 will also rise via the attachment piece 6 as the ram rises, and the measuring movable body 10 will always have a tension spring 25.
Since the pulling force is applied in the direction of arrow A by the force, it maintains contact with the guide element 4 and immediately responds to the rise of the guide element 4 by starting to move horizontally along the guide rail 3 and setting. When the ram 32 traverses over an equal dividing distance L' according to the number of divisions, the detector attached to the moving body 10 in advance comes into contact with the division signal transmitter installed on the numerical selection distribution mechanism side, and the ram 32 rises. The rotation of the drive motor is stopped, and the ram 32 is stopped at a position where the ram 32 has risen by a certain amount, and a volume of powder A corresponding to this rise is pushed upward from the open end of the container 30, and the moving body 10
When the scraping plate 38 has stopped, the scraping plate 38, which is set to be interlocked in advance, moves back and forth on the surface plate 37, and the chute 40 is directed toward the open end 3.
The powder and granules rising upward from 1' are scraped and sent out, and then put into the packaging bag 50.

When this scraping operation is completed, the ram 32 is again started to be driven upward by a command from a preset electric control mechanism, and thereafter operates intermittently in the same manner as described above.
Repeat the number of times according to the number of divisions in the entire forward stroke of 0, and divide when the pivot point C of the inclined guide rod 12 reaches a position that coincides with the vertical line passing through the movable intersection d of the inclined guide rod 12 and the guide element 4. The operation is completed, i.e. the ram 3 inside the body 31 of the container 30
The top surface of the movable body 10 is aligned with the opening end 31'1, and the entire amount of the powder to be divided has been distributed.At this point, the forward movement of the movable body 10 is stopped, and after that, for the return process. The driving mechanism of the chino 22 is activated, and the movable body 10 returns to its original position and is stopped.

During this time, the ram 32 of the metering container 30 also reverses its drive motor and returns to its set position.

Therefore, once this one cycle is completed, unless the total amount to be divided is changed, the measuring container 30 may be filled again with the powder to be divided and the above operation may be repeated.

Furthermore, when changing the number of divisions without changing the internal capacity of the weighing container 30, the division numerical value selection and distribution mechanism can be used to change the number of divisions to the required number. The amount of rise of the ram 32 in the container 30 is set, and the powder and granules can be separated into required amounts.

The above describes a method in which the movement of the motor that drives the ram on the measuring container side is used as a reference, and the movement of the motor is controlled by the numerical selection distribution mechanism attached to this by making the measuring moving object follow the movement. Instead, it is also possible to control the raising operation of the ram based on the movement of the measuring moving body, and a specific example of such a system will be described as follows.

Note that the same parts as in the above embodiment are given the same reference numerals and the same names.

In FIGS. 4 to 6, a measuring moving body 10 is provided on the fuselage 1 and is movable along a guide rail 3t as in the previous example, and this moving body 10 is equipped with a support 11 and a position setting rod 14 that can be raised and lowered. Similar to the above example, a tilt guide rod 12 is attached, and a deceleration motor 2 attached to the moving body 10 is attached to the position setting rod 14.
A rack gear 15 that meshes with a pinion gear 20 fixed to the end of the output shaft 27' of No. 7 is attached, and the rack gear 15 is configured to be raised and lowered by the motor 27.

Note that the deceleration motor may be equipped with a brake lever or a clutch may be provided so that the rotational force can be turned on and off at any time.

The measurement movable body 10 is connected to a small pitch power transmission chain 22 suspended over a required section at its lower position by a connecting fitting 23, and the chain 722 is hooked onto one of the chain wheels 24, 24' A drive motor (not shown) connected to the shaft is driven intermittently, or between the motor and the chain axle (
A device such as a clutch mechanism that can turn power transmission on and off is used to allow the vehicle to travel intermittently, and when going back, it travels to a fixed position and then stops.

As for the numerical selection and distribution mechanism for division, the same one as in the previous embodiment is adopted, and it is connected to an electromagnetic clutch or a mechanism belonging thereto that transmits the driving force of the drive machine, which is constantly rotating during operation, to the check 722. , so that the moving body 10 travels a required distance and stops repeatedly by being electrically activated.

Regarding the relationship between the inclined guide rod 12 provided on the measurement movable body 10 and the internal ram 32 of the measuring container 30 similar to the above-mentioned embodiment, the inclined guide rod 12 (with respect to the guide member 4' from both above and below) , 4' are brought into contact with each other, and both guide pieces 4/
The piece 8 is an arm 60 that is attached to the ram 320 of the weighing container 30 and the ram 33 of the weighing container 30, as shown in FIG.
The pair of guides is mounted so that the center of the pivot pin 8' of the piece 8 intersects the axis of the inclined guide rod 12, and the guide pair is mounted to the pillar 11. As shown in FIG. 6, the metal fitting 13 is provided with a mounting portion 13'' at a distal end appropriately offset from the position of the pivot pin 13', so that the pair of guides can reach the pivot point.

The means for raising and lowering the weighing container 30 is constructed in the same manner as in the previous embodiment, and the ram 32 is raised and lowered via an arm 60 by rotating, for example, a screw shaft 7 by a separate drive motor.

To explain the operation of this type of device, first, as in the above example, the motor is driven to fill the weighing container 30.
Then, the required amount of powder to be divided is densely packed into this measuring container 30, and at the same time, the required number of parts is set in the numerical selection and distribution mechanism l for division, and each part is When driving, the drive mechanism (in the illustrated example, the winding is the drive side chain of the conduction chain The vehicle moves by intermittently transmitting driving force in the drive unit connected to the vehicle.

Then, due to the intermittent movement, the inclined guide rod 12 whose inclination angle θ was previously set moves its movable tip to the slide bearing 1.
Since the position setting rod 14 supported through the position setting rod 7 is fixed by meshing with the attached rack gear 15 and the pinion gear 20 driven by the lifting operation motor 27, the position setting rod 14 can be moved while maintaining the set inclination angle. The pair of guide elements 4' in contact with the inclined guide rod 12 rises while rolling by tan θ Mobile object 10
When the movable body 10 has been displaced by one set movement section, the detector attached to the movable body 10 reaches the dividing point in the numerical selection distribution mechanism and issues an instruction signal to stop the moving body 10, which corresponds to one rise of the ram 32. When the volume of granular material A is pushed upward from the open end of the container 30 and the intermittent feeding of the movable body 10 stops, the scraping plate 38, which has been arranged to be interlocked in advance, moves to the surface plate 37.
It makes one reciprocation over the top of the chute 40 to scrape and send out the granular material that has risen upward from the open end 31', and is thrown into the packaging bag 50.

Thereafter, such an operation is repeated a number of times according to the number of divisions during the entire forward travel t of the moving body 10, and the division work is completed by moving to the terminal position in the same manner as in the previous embodiment.

Immediately after this forward stroke is completed, the drive mechanism is reversed to return the movable body 10 to its original position, and in conjunction with this, the ram 32 is also lowered.

In this case, if necessary, the ram can be moved up and down in conjunction with the displacement of the movable body via the arm to which the pair of guides is attached, and can be moved up and down by a separate power.

In this way, according to the present invention, by selectively setting the capacity and the number of divisions, each operating section operates in sequence in the order set in advance in the electrical control mechanism for other operations. However, the operation of dividing the powder or granular material into equal amounts is automatically performed, and each setting can be selected and set arbitrarily to perform the equal division work.

In addition, instead of the direct connection operation structure between the guide and the ram of the measuring container in the description of the above embodiment, a small guide other than the above embodiment may be used, and a sensor that detects the displacement of the guide electrically or photoelectronically may be used. The elevating and lowering of the ram may be separately operated by power, and the equal amount side operation may be performed.

Further, for the traverse movement of the moving body, in addition to the chino drive, it is also possible to arbitrarily adopt a mechanism that engages a rack gear and a pinion, or a mechanism that rotates and feeds a screw shaft.

In addition, an electrical display means is installed in advance on the ram movement related part of the measuring container so that the measuring container can be detected (by straining it), and by commanding a predetermined volume (the corresponding position). Various means can also be adopted for setting the measuring volume, such as rubbing to set the required volume.
