Japanese Patent Laid-Open No. 5-213301

  In the conventional packaging device, when the rotary table is rotated to perform the next packaging, the partition member is kept in contact with the annular groove. If it does so, friction and a catch may generate | occur | produce between a partition member and the groove bottom face of an annular ditch | groove, and a partition member may vibrate finely, In that case, smooth packaging operation | movement might not be performed.

  In view of the above problems, an object of the present invention is to provide a method for controlling a packaging device that can perform a smooth packaging operation and a packaging device.

  The present invention includes a rotatable rotary table having an annular groove formed on the upper surface, a rotatable cutting member that cuts out the granular material on the annular groove and cuts it in the radial direction of the annular groove, A disc-shaped partition member that is arranged in parallel to the cut-out member on the downstream side in the rotation direction of the rotary table and partitions the powder particles in the circumferential direction, and sequentially divides the cut-out powder particles A method of controlling an apparatus, wherein when the cutting member is rotated to cut out a granular material in a predetermined circumferential direction on the annular groove, the outer peripheral portion of the partition member is brought into contact with the upper surface of the annular groove to It is characterized in that the partition member is separated from the annular groove immediately before the granular material is fed by rotating the rotary table to cut out the granular material in the next circumferential predetermined region after the granular material is cut out.

  According to the above method, when the rotary table is rotated for the next packing, the partition plate is separated from the annular groove so that friction or the partition plate is caught between the annular groove and the partition plate. Therefore, even if the rotary table is rotated, the partition plate does not vibrate finely.

  The present invention includes a rotary table having an annular groove formed on the upper surface and rotatable around a vertical axis, and an annular groove to cut out the powder on the annular groove so as to cut out in the radial direction of the annular groove. A cutting member that can rotate around the horizontal axis that is the center of curvature of the groove, and a disk-shaped partition member that is arranged in parallel to the cutting member on the downstream side in the rotation direction of the rotary table and partitions the granular material in the circumferential direction. And an operation unit for operating the partition member so as to be in contact with and away from the annular groove, and is a packaging device for sequentially packaging the cut out powder particles, and the cutting member is rotated around the horizontal axis. When cutting out the granular material in the circumferential predetermined region on the annular groove, after driving the operating portion so that the outer peripheral portion of the partition member contacts the upper surface of the annular groove, and after cutting out the granular material Turn the rotary table around the vertical axis to cut the powder in the next circumferential area Just before by rolling Send granular material, and the partition member, characterized in that the control means for controlling the driving of the operation unit so as to separate from the annular groove is provided.

  In the above configuration, when the cutting member is rotated about the horizontal axis for packaging, the control means outputs a drive stop signal to the rotation driving unit of the rotating table, and the rotating table rotates for the next packing. Immediately before outputting the drive signal to the drive unit, the control means outputs the drive signal to the drive unit of the operation unit, so that when the operation unit is driven and the partition member is separated from the annular groove, the cut-out member is annularly recessed. By separating from the groove, there is no friction or catching between the partition member and the annular groove even when the rotary table is rotated around the vertical axis for the next packing, so the partition member vibrates finely. There is nothing to do.

  According to the control method of the packaging device of the present invention, the partition plate is separated from the annular groove when the rotary table is rotated for the next packaging. Since the partition plate is not caught and the partition plate does not vibrate finely even when the rotary table is rotated, a smooth packaging operation can be performed.

  According to the packaging device of the present invention, before the rotary table is rotated for the next packaging operation, the control means outputs a drive signal to the drive unit of the operation unit to separate the partition member from the annular groove. Therefore, even if the rotary table is rotated for the next packaging, there is no friction or catching between the partition member and the annular groove, so that the partition member does not vibrate finely and smooth packaging. The action can be performed.

Thus, the rotating body 13, the mounting support body 32, the wide cut-out plate 7 </ b> A, and the cover 8 are integrated by receiving a pressing force in the axial direction of the rotation transmission shaft 40.

Here, the narrow cutout plate 7B will be described. The narrow cut-out plate 7B scrapes the powder 4 dammed up by the partition plate 6 from the groove 3 in a region partitioned between the partition plate 6 and the cover 9, and is located laterally of the rotary table 2, that is, radially outside. It is for cutting out to the hopper 20 arrange | positioned in the direction, and is fixed by being pinched | interposed into the rotary body 13 and the attachment support body 32. FIG.
This narrow cut-out plate 7B is preferably used for cutting out at least the first pack in order to cut out the powder 4 supplied on the groove 3 in order to sequentially pack it into small packages.

  The narrow cut-out plate 7B has a cut-out plate body 60, an elastic blade (scraping blade) 61, and a spacer 62a. The cut-out plate body 60 is integrally formed from a distal end plate portion 63 and a proximal end plate portion 64, and the distal end plate portion 63 and the proximal end plate portion 64 are formed to have the same width.

The tip plate 63 is provided with an elastic blade 65 that protrudes further forward. The elastic blade 65 is formed in a plate shape whose tip is cut at an acute angle so as to contact the groove bottom surface 3 a and scrape off the powder 4, and the elastic blade 65 is compared with the width B 3 of the tip plate portion 63. It protrudes to the width direction one side (partition plate 6 side which is the downstream side) of the front end plate portion 63 so as to be formed slightly larger.
Further, the elastic blade 65 is heat-sealed to the tip plate portion 63 and fixed to the tip plate portion 63 so as to form a coating portion 66 having a uniform thickness t2 that covers the downstream side surface of the tip plate portion 63. Has been.

  The spacer 62a is formed integrally with the elastic blade 22 continuously. The spacer 62a is extended on the downstream side surface of the cut-out plate body 60 with a uniform width B4 along the spacer 62a. That is, the width B4 is substantially equal to the width of the covering portion 66 that is a portion protruding in the width direction of the tip plate portion 63 in the elastic blade 65.

  Parallel retaining protrusions 67 are fixed to the base end plate portion 64 and spaced apart from each other by a predetermined distance L3 along the width direction of the base end plate portion 64. As a fixing means for the retaining protrusion 67, for example, heat fusion is used. The thickness of the retaining protrusion 67 is equal to the thickness t2 of the covering portion 66. The cross-sectional shape of the retaining protrusion 67 is formed in a hemispherical shape, and is formed so as to be continuous with the covering portion 66 through a sheet portion 68 having an extremely thin thickness as compared with the covering portion 66.

  As shown in FIG. 3, a support recess 70 for inserting and supporting the proximal end plate portion 64 of the narrow cutout plate 7 </ b> B in the width direction is provided at the center of the attachment support 32 on the upstream side wall 34 of the attachment support 32. On the other hand, it is displaced by a predetermined distance L4. The direction of displacement relative to the center of the mounting support 32 is opposite to that of the wide cut-out plate 7A. The support recess 70 is formed slightly thicker than the thickness of the base end plate portion 64 of the narrow cutout plate 7B, and a hemispherical retaining recess 71 into which the retaining projection 67 is inserted is formed in the support recess 70. It is formed continuously.

  The depth of the support recess 70 is formed to be substantially equal to the width of the base end plate portion 64, and the spacer 62 a protrudes downstream from the support recess 70 when the base end plate portion 64 is mounted. When the base end plate portion 64 is attached to the support recess 70, the distal end plate portion 63 protrudes from the attachment support body 32 to the opposite side to the distal end plate portion 24 of the wide cutout plate 7A so that the distal end plate portion 63 is along the radial direction of the attachment support body 32. It is like that.

  In the scraping device 5 having the above-described configuration, the downstream outer peripheral edge 45 b of the end cap 45 is formed on the cover 8 by firmly screwing the screw hole 45 a of the end cap 45 to the tip 40 a of the rotation transmission shaft 40. The rotating body 13, the mounting support body 32, the wide cut-out plate 7 </ b> A and the cover 8 are integrated by receiving the pressing force in the axial direction of the rotation transmission shaft 40 by being pressed against the upstream plate surface.

  When the base end plate portion 25 of the wide cut-out plate 7A is attached to the support concave portion 35 of the support body 32, one spacer 23b is configured to protrude upstream from the support concave portion 35, and the base end plate portion 25 is Since the other spacer 23a protrudes further downstream from the downstream end face of the mounting support 32 when mounted, the screw hole 45a of the end cap 45 is provided at the tip 40a of the rotation transmission shaft 40. By firmly screwing, one spacer 23b is pressed against the cover 8 from the downstream side, and the other spacer 23a is pressed against the plate surface of the partition plate body 10 from the upstream side. Since one spacer 23b is made of an elastic body, an elastic repulsive force corresponding to the amount of compression is generated, one spacer 23b presses the cover 8, and the other spacer 23a is a partition plate. Since the main body 10 is pressed, there is no room for generating a gap between the wide cut-out plate 7A and the partition plate main body 10 and between the wide cut-out plate 7A and the cover 8.

For this reason, even if the scraping device 5 is rotationally driven to cut the powder 4 into the hopper 20, the powder 4 is caught between the wide cut plate 7 </ b> A and the partition plate body 10, the wide cut plate 7 </ b> A and the cover 8. It is possible to prevent the inconvenience of being lost.
In this way, when the powder 4 is packaged, the powder 4 does not remain between the members of the scraping device 5, so that even when a small amount of the powder 4 is packaged, the necessary packaging accuracy is ensured. be able to.

  Further, since the partition plate 6 and the wide cut-out plate 7A are assembled as separate members, for example, when the damming body 11 or the elastic blade 22 is damaged by sliding (by sliding the groove bottom surface 3a). Since each member can be maintained (replaced) separately, an increase in running cost can be suppressed.

  The spacers 23a and 23b are provided on the wide cut-out plate 7A. However, the present invention is not limited to this, and a member having a function corresponding to the spacer is provided on the cover 8 and the partition plate main body 10 side. By doing so, the generation of the gap can be prevented.

  In the narrow cut-out plate 7B, the base end plate portion 64 is inserted into the support recess 70, and the retaining protrusion 67 is inserted into the retaining recess 71, and is attached to the mounting support 32, and the end cap 45 is attached. When tightened to the distal end portion 40a of the rotation transmission shaft 40, the spacer 62a presses the plate surface of the partition plate body 10 on the upstream side, so that there is room for a gap to be generated between the narrow cutout plate 7B and the partition plate body 10. Disappears.

  For this reason, even if the scraping device 5 is rotationally driven to cut out the powder 4 into the hopper 20, it is possible to prevent the inconvenience that the powder 4 is caught between the narrow cutout plate 7 </ b> B and the partition plate body 10. Therefore, even when a small amount of powder 4 is packaged, the required packaging accuracy can be ensured.

First, while supplying powder 4 to the groove 3 of the turntable 2 from a supply means such as a feeder (not shown), the drive motor is driven to rotate the turntable 2 around the vertical axis to thereby spread the powder in the circumferential direction of the groove 3. Shake 4 At this time, the large curvature portion 106 or the small curvature portion 107 of the lifting cam 104 is brought into contact with the lower surface 86c of the side plate 93 of the transmission arm member 86, and the wide cut plate 7A and the narrow cut plate 7B are separated from each other in the scraping portion. By setting it as the attitude | position Y, the scraping part is spaced apart from the groove bottom face 3a (for example, refer FIG. 5).

  (A), (b), (c), and (d) of FIG. 8 are schematic plan views in the middle of cutting out the first, second, third, and fourth packages in the extraction of powder 4 respectively. . 9A is a schematic front view in the middle of the cutting operation for the first package, FIG. 9B is a schematic front view in the middle of the cutting operation for the second package, and FIG. 9C is a cut out of the second package to the third package. (D) is a schematic front view before cutting out the third package, and (e) is a schematic front view in the middle of the cutting operation of the fourth package.

Next, based on the number of packages input to the number-of-packaging input means 111, when the number of packages is, for example, 21 packages to 45 packages, for the first package, the wide cutting plate 7A in the scraping part, The powder 4 is cut out using the narrow cut-out plate 7B among the wide cut-out plates 7B.
That is, if necessary, the rotation drive motor 87 is driven to rotate (rotate) the rotation transmission shaft 40, so that the narrow cutout plate 7 </ b> B is radially inward of the turntable 2 on the downstream side in the cutout direction. The lifting / lowering motor 102 is driven to rotate the lifting / lowering cam 104 around the lifting / lowering horizontal shaft 103 to lower the scraping portion.

By doing in this way, the partition plate 6 can dam the powder 4 in the circumferential direction. Subsequently, the rotational drive motor 87 is driven to rotate the scraping portion around the rotation transmission shaft 40, so that the powder 4 in the region partitioned in the circumferential direction by the partition plate 6 and the cover 9 becomes the narrow cutout plate 7B. Is cut out radially outward of the turntable 2 as an amount of powder 4 according to the width (see FIG. 9A).
The powder 4 cut out in this way is taken as the first package.

  By the way, when the powder 4 is cut out by the narrow cutout plate 7B, a cover 9 is provided adjacent to the upstream side of the narrow cutout plate 7B, and this rotates when cutting out, so that the narrow cutout plate 7B The powder 4 remains in a streak pattern on the groove bottom surface 3a along the upstream locus (indicated by a broken line a1 in FIG. 8A).

  Therefore, as the operation of the second parcel that is the next cut-out, as shown in FIG. 8B, the narrow cut-out plate 7B and the wide cut-out plate 7A whose downstream side positions are matched are cut out. In this manner, the powder 4 remaining in the stripe shape is scraped off at the tip of the wide cut-out plate 7A including the powder 4 remaining in the shape of the stripe after finishing the cutting of the powder 4 in the first package. This is cut out as a second package (see FIG. 9B).

  Similarly, during the cutting operation by the wide cut-out plate 7A to cut out the powder 4 of the second package, the powder 4 is striped on the groove bottom surface 3a along the upstream trajectory of the wide cut-out plate 7A by the rotation of the cover 8. It will remain (indicated by a broken line b1 in FIG. 8B).

  (C) of FIG. 8 is an explanation of the cutting operation of the third package, but since the powder 4 is cut out using the wide cutting plate 7A, there is no powder 4 below the scraping portion. For this reason, it is necessary to send the powder 4 downstream by rotating (turning) the rotary table 2 around the vertical axis by an angle corresponding to the number of packages. Here, in cutting out the powder 4 of the first and second packages, the powder 4 is caught between the outer peripheral portion of the partition plate 6 (the radially outer end 18 of the weir body 11) and the groove bottom surface 3a. In addition, the outer peripheral portion of the partition plate 6 is in close contact with the groove bottom surface 3a. When the rotary table 2 is rotated around the vertical axis in this state, the partition plate 6 vibrates finely.

  Therefore, when the rotary table 2 is rotated about the vertical axis for the next packaging (in this case, when the second package is cut out and the third package is cut out), the control means 112 is used for rotational driving. Immediately after the motor 87 detects a drive amount that has just finished the previous cutting operation or immediately before rotating the rotary table 2, it outputs a drive signal to the drive unit of the lifting motor 102.

By doing so, the large curvature portion 106 or the small curvature portion 107 of the raising / lowering cam 104 comes into contact with the lower surface 86c of the side plate 93 and becomes the separation posture Y from the cutting posture X of the wide cutting plate 7A and the narrow cutting plate 7B. (See FIG. 9 (c)).
In the separation posture Y, the partition plate 6 is also separated from the groove bottom surface 3a. Therefore, even if the rotary table 2 is rotated around the vertical axis, no friction occurs between the partition plate 6 and the groove bottom surface 3a of the rotary table 2. The plate 6 does not vibrate finely, and the powder 4 is not rubbed between the partition plate 6 and the groove bottom surface 3a.
Then, the control means 112 outputs a drive signal to the drive unit of the drive motor, and when the control means 112 detects that the rotary table 2 has rotated around the vertical axis by an angle corresponding to the set number of packages, the control means 112 112 outputs a stop signal to the drive unit of the drive motor.

Subsequently, the control unit 112 outputs a drive signal to the drive unit of the lifting motor 102 in order to set the wide cut plate 7A or the narrow cut plate 7B to the cutting posture X (see FIG. 9D), The elevating horizontal shaft 103 is rotated until the flat portion 105 of the elevating cam 104 faces the lower surface 86c of the side plate 93 below. And the control means 112 outputs a drive signal to the motor 87 for rotation drive, rotates the rotation transmission shaft 40, and cuts out the powder 4 with the wide cut-out plate 7A. At this time, the third package is cut out by tracing the powder 4 remaining in a streak pattern by the second package cutting operation (see FIG. 8C).
Accordingly, the powder 4 remaining in a streak shape is removed by the cutting operation of the second package.

  Even when the third package to the fourth package are cut out, the control is performed immediately after detecting the driving amount of the rotary drive motor 87 that has just finished the third package cutting operation or immediately before the rotary table 2 is rotated. The means 112 outputs a drive signal to the drive unit of the lifting motor 102 to raise the scraping unit from the groove bottom surface 3a. Thereby, the partition plate 6 does not vibrate finely, and a smooth packaging operation can be performed.

  When the rotary table 2 rotates about the vertical axis by an angle corresponding to the number of packages, the control unit 112 outputs a drive signal to the drive unit of the lifting motor 102 so as to lower the scraping unit, and FIG. As shown in Fig. 8 (d), the scraping part is lowered as shown in Fig. 8 (d), and the streak powder 4 (shown by the broken line c1 in Fig. 8 (c)) generated by the cutting operation of the third packet is shown. It is removed from the groove bottom surface 3a.

  As described above, according to the embodiment of the present invention, the wide cut plate 7A and the narrow cut plate 7B which are narrower than the wide cut plate 7A are provided as the cut members. The powder 4 is cut out by the plate 7B, and then, the striped powder 4 generated by the previous cutting operation is removed by the wide cutting plate 7A, and the amount of the powder 4 corresponding to the cutting amount of the powder 4 by the narrow cutting plate 7B is removed. Cutting out can be performed by the wide cutting plate 7A.

  The amount of the first powder 4 to be cut out can be determined by rotating the rotary table 2 around the vertical axis while storing the powder 4 on the downstream side of the partition plate 6 and storing it. The amount of the powder 4 for cutting out can be adjusted by the rotation angle of the turntable 2, so that even if the circumferential length of the groove 3 is determined, the first package is narrowed by the narrow cutout plate 7B. By cutting out, a large number of packages can be easily performed, and the degree of freedom in adjusting the package amount of the powder 4 can be increased.

Furthermore, according to this embodiment, the scraping part is lifted from the groove bottom surface 3a immediately before the turntable 2 is rotated around the vertical axis for the next packing operation. The phenomenon that the partition plate 6 vibrates finely due to rubbing can be eliminated.
In addition, the raising amount at the time of raising a scraping part from the groove bottom face 3a is not specifically limited, The partition plate 6 and the groove bottom face 3a should just not rub.

  In the above embodiment, the groove has been described with the configuration of the annular groove, but the present invention is not limited to this, and even if the groove has a linear configuration or a configuration close to this, the powder is moved by moving the portion where the groove is provided. In a packaging device that cuts particles in the direction perpendicular to the groove, the powder or powder on the groove is intermittently moved from the upstream side to the downstream side to sequentially cut the particles. Can be applied to packaging equipment.
