Description

  The present invention relates to a tablet supply device for supplying tablets (including capsules) to a line.

  Conventionally, for example, a chute apparatus is used to supply tablets to a line such as a packaging line. This is formed by connecting a cylindrical chute below the product container, positioning a hopper or conveyor connected to the line at the lower end of the chute, and discharging the tablets received in the product container onto the hopper or conveyor. Is. In the line, the supplied tablets are sequentially packaged, but the chute apparatus is instructed to accept a fixed amount of tablets and send them in necessary amounts. Therefore, the chute device cannot supply continuously, and a shutter mechanism that stops supply in a timely manner according to a command is required. No suitable example is found as a conventional shutter mechanism. In the first place, there are few examples using a chute device, and there is an example of Unexamined-Japanese-Patent No. 8-225127 (bucket conveyor supply part structure) if it dares to show.

  In JP-A-8-225127, a dropping hole is provided in the lower part of a tablet receiving container (hopper), an oblique chute with a shutter is provided below the hole 29, and this chute is arranged forwardly below that chute. It is provided so as to be able to move forward and backward with respect to the bucket, and the shutter is opened in conjunction with the forward and backward movement, and a tablet (capsule) is put into the bucket. Tablets put into the bucket are lifted by a tower device and supplied to a packaging device or the like.

  What is absolutely necessary in these apparatuses is that they are supplied in a required amount in accordance with a command and that the tablets are not scratched or damaged.

  Japanese Patent Application Laid-Open No. 11-105803 (solid material filling apparatus) has an example of a controller that variably controls a solid material supplied to a hopper in a plurality of stages based on a measurement result of a measuring device. It is shown.

  However, since the conventional tablet supply device is designed to be closely related to the line beyond the tablet supply function required by the tablet supply device, for example, it is configured to be able to supply only to the bucket, the special specification However, there is a problem that the apparatus is not versatile and the apparatus is complicated and expensive.

Also, as disclosed in Japanese Patent Laid-Open No. 8-225127, when the conduit is controlled to be opened or closed by the shutter plate 33, a baffle plate 34 is required to prevent the tablet from being damaged. The baffle plate 34 has to have a steep inclination angle of 30 to 60 ° because the tablet flowing from above must flow downward. Accordingly, since the inclination angle of the shutter plate 33 is determined in accordance with this, the inclination angle of the shutter plate 33 is steep. If the inclination of the shutter plate 33 is steep, the area of the hole formed in the shutter plate 33 must be increased, the length becomes longer, the moving distance of the shutter plate increases, and the apparatus becomes larger. It will be something. Moreover, if the inclination angle of the shutter plate 33 is steep, the crossing angle with the pipe line becomes an acute angle, and the tablet may be pulled into this acute angle portion and may be damaged depending on the type of tablet.

  An object of the present invention is to provide a highly versatile tablet supply device that can smoothly supply various tablets (including capsules) to various lines with a simple configuration and at a low price.

  In order to solve the above problems, the present invention provides a cylindrical charging tube having an inner diameter of D1 mm, which is connected to the lower side of a product container and can flow down tablets (including capsules) charged in the product container. A shutter device arranged below the tube and capable of controlling the flow of the tablet, and a tablet which is arranged below the shutter device and has an inner diameter equal to or larger than the inner diameter of the input tube, and flows from the input tube into a line. The shutter device has the following requirements (1) to (6).

(1) It has a valve plate provided with a hole having a diameter D2 slightly smaller than the inner diameter D1 of the charging pipe.

(2) The valve plate is disposed with an inclination angle θ1 (15 to 25 °) between the input pipe and the discharge pipe.

(3) A position in which the hole portion of the valve plate deviates from the inner diameter of the input tube from the state (open state) in which the hole portion of the valve plate is aligned with the inner diameter D1 of the input tube along the inclination angle θ1. A valve plate drive motor (including a cylinder) that is raised until it reaches the (partitioned state) or vice versa is provided.

(4) Enough to overhang the upper end of the valve plate on the inner side of the input pipe from the inner surface of the input pipe to a position beyond the center of the input pipe, and to allow the tablet dropped on the upper part to flow downward A baffle plate having a shape in which a crescent-shaped product dropping port is left is provided in front of the tilted angle θ2 (30 to 60 °).

(5) A surface tri member extending inward of the hole of the valve plate is provided at a portion where the inner surface of the input tube and the valve plate intersect with each other below the input tube.

(6) A skirt portion is provided between the baffle plate and the valve plate so that a gap between them is about 1.5 to 3 times the diameter of the tablet.

  With the above configuration, the tablet charged into the product container is flowed from the charging tube to the discharge tube via the shutter device and supplied to the line. Since the product container and the line are connected to each other only by a pipe line, there is versatility.

  Since the valve plate of the shutter device has a diameter D2 (D2 <D1) that is the same as or slightly smaller than the inner diameter D1 of the input pipe, there is no gap between the input pipe and the discharge pipe when the shutter is opened. In addition, with the movement of the valve plate, there is no gap between the two due to the thickness of the valve plate, and even a small tablet can be drawn into the gap.

  Since the inclination angle θ1 of the valve plate is 15 to 25 °, it is not necessary to make the shape of the hole of the valve plate elliptical, and it is not necessary to increase the moving distance of the valve plate, thereby reducing the size of the device. Can be

  Valve plate movement is controlled by opening and closing the hole of the valve plate toward and away from the inner diameter of the input pipe, so the opening and closing operation can be configured with general cylinders, racks, and pinions, simplifying the device be able to.

  Since the baffle plate has an inclination angle of 30-60 ° and a crescent-shaped product drop opening is left in front, the tablet can be sent to the crescent-shaped drop mouth, and below the baffle plate A space can be formed.

  A skirt is provided below the baffle plate, and a space in which the gap between the baffle plate and the valve plate is adjusted to about 1.5 to 3 times the diameter of the tablet (about 1 to 3 cm) can be formed. Therefore, it is possible to reliably prevent the tablet from entering the upper part of the valve plate and to smoothly operate the valve plate.

  At the portion where the inner surface of the input pipe intersects the valve plate, a surface tri member is provided that extends inside the hole of the valve plate when the valve plate is in a closed state, so the diameter of the valve plate hole is smaller than the inner diameter of the input pipe Nevertheless, the tablet can be smoothly supplied to the discharge pipe.

  Since there is a space below the baffle plate even while the tablet is flowing in the input tube, the inner diameter of the input tube can be partitioned by partitioning the valve plate hole with respect to that space, and the tablet flow is stopped. it can.

  Even when the tablet flow is stopped and the tablet is filled in the input pipe, the above-mentioned face tri is provided below the input pipe, so that the tablet intersects the input pipe with the valve plate. There is no fear of being drawn into the department.

  Since the tablet supply device of the present invention has the configuration as described in the claims of the utility model registration, it can be applied to various tablets in various lines and is versatile.

  Since the hole of the valve plate of the shutter device has a diameter D2 that is slightly smaller than the inner diameter of the input pipe, it can be configured without a gap between the input pipe and the discharge pipe when the shutter is opened. A gap associated with the thickness does not occur, and even a small tablet can be smoothly flowed without being drawn into the gap.

  Since the inclination angle θ1 of the valve plate is 15 to 25 °, it is not necessary to make the shape of the valve plate hole elliptical in alignment with the input pipe, and it is not necessary to increase the valve plate moving distance accordingly. The device can be miniaturized.

  Since the baffle plate has an inclined angle of 30 to 60 ° and has a crescent shaped product dropout in the front, tablets can be smoothly fed to the crescent shaped dropout, and below that A space can be formed.

  Since a skirt is provided below the baffle plate, a space adjusted to about 1.5 to 3 times the diameter of the tablet (about 1 to 3 cm) can be formed between the baffle plate and the valve plate. It is possible to reliably prevent the tablet from entering the valve plate and to operate the valve plate smoothly.

  At the portion where the inner surface of the input pipe intersects the valve plate, a surface tri member is provided that extends inside the hole of the valve plate when the valve plate is in a closed state, so the diameter of the valve plate hole is smaller than the inner diameter of the input pipe Nevertheless, the tablet can be smoothly supplied to the discharge pipe without hitting the surface along the hole of the valve plate.

  In the case of a supply stop command, since a sufficiently large space exists below the baffle plate even when the tablet is flowing in the charging tube, it can be partitioned at high speed.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. 1 is a longitudinal sectional view of a tablet supply device according to an embodiment of the present invention, FIG. 2 is a transverse sectional view taken along line F2-F2 of FIG. 1, and FIG. 3 is a plan view of a valve plate.

  As shown in FIG. 1, the tablet supply device 1 of the present invention has a cylindrical shape with an inner diameter D1 mm that is connected to a lower part of a product container 2 and can flow a tablet (including a capsule) 3 placed in the product container 2 downward. An input pipe 4, a shutter device 5 disposed below the input tube 4 and capable of controlling the flow of the tablet 3, and an inner diameter disposed below the shutter device 5 and having an inner diameter equal to or greater than that of the input tube 4 D3 includes a discharge pipe 6 for supplying the tablet 3 flowing from the input pipe 4 to the line. The partition device 7 provided at the upper portion of the input tube 4 is generally operated when the tablet 3 is replaced, when the system is stopped, or when it is not used.

  The shutter device 5 has the following requirements (1) to (6).

(1) It has a valve plate 9 (FIG. 3) provided with a hole portion 8 having a diameter D2 slightly smaller than the inner diameter D1 of the input pipe 4 of the pipe.

(2) The valve plate 9 is disposed at an inclination angle θ1 (15 to 25 °) between the input pipe 4 and the discharge pipe 6.

(3) From the state in which the hole 8 of the valve plate 9 is aligned (centered) with the inner diameter D1 of the input tube 4 (open state in FIG. 1), the hole 8 is the inner diameter of the input tube 4 A valve plate drive air cylinder (not shown) is provided that is raised until it comes to a position (partitioned state) deviated from, or vice versa.

(4) The tablet 3 that protrudes from the inner surface of the input pipe 4 to a position beyond the center of the input pipe 4 and is dropped on the upper side of the valve plate 9 inside the input pipe 4 and above the upper end of the valve plate 9. A baffle plate 11 is provided that is inclined by an angle θ2 (30 to 60 °) sufficient to flow downward and leaves a crescent-shaped product drop port 10 in front of it.

(5) A surface tri-member 12 extending inside the hole of the valve plate 9 is provided at a portion where the inner surface of the input tube 4 and the valve plate 9 intersect with each other below the input tube 4.

(6) A skirt portion 13 is provided between the baffle plate 11 and the valve plate 9 so that a gap S1 between them is about 1.5 to 3 times the diameter of the tablet.

  The numerical values of the examples are D1 = D3 = 97.6 mm, D2 = 95 mm, θ1 = 20 °, and θ2 = 45 °.

  The valve plate 9 is housed in a case 16 composed of an upper plate 14 and a lower plate 15 so as to be slidable vertically and obliquely. The case 16 is provided with a hole larger than the inner diameter D1 of the charging tube 4. An example numerical value of the inner diameter of the hole is 105 mm.

  In FIG. 1, the valve plate 9 is shown lowered and fully opened. In this state, the hole 8 of the valve plate 9 is matched with the inner diameter of the input tube 4. When the valve plate 9 is driven in the direction of the arrow 17 and the valve plate 9 is lifted, the hole 8 moves to the closed position P8 (shut). Regarding the lower end position of the valve plate 9, the fully open position is indicated by 9 (open) and the fully closed position is indicated by 9 (shut). Tablet flow is indicated by arrows 18. A space S1 formed above the valve plate 9 and a space formed below the valve plate 4 are denoted by S2. A hopper and a conveyor are disposed below the discharge pipe 6 and communicate with the line 19.

  A flange 20 is provided at an intermediate portion of the discharge pipe 6, a cylinder driving base 21 is provided on the flange 20, an air cylinder (not shown) is provided on the driving base 21, and the valve plate 9 is indicated by an arrow 17. Drive up (up) or vice versa (down).

  The operation of the above configuration will be described. In the state of FIG. 1, the hole 8 of the valve plate 9 is aligned (centered) with the inner diameter of the input tube 4. The tablet 3 placed in the product container 2 enters the input tube 4, hits the upper surface of the baffle plate 11 having a steep inclination angle θ 2, slides along the arrow 18, and enters the dropping port 10. Since the angle θ2 is steep, the tablet 3 can be reliably fed into the dropping port 10.

  Since the baffle plate 11 extends beyond the center position of the input pipe and is guided with respect to the drop port 10, a sufficiently large space can exist below the baffle plate 11, and the baffle plate 11 Since the skirt portion 13 is provided below, it is possible to take wide spaces S1 and S2 below. The distance between the valve plate 9 and the skirt portion 13 is 1 to 2 cm as an example value.

  When the tablet passes through the hole 8 of the valve plate 9, the diameter D2 of the hole 8 is set to a slightly small value, so that the tablet hits this difference and the flow is not stopped here. . Since the periphery of the hole 8 is rounded, there is no risk of scratching the tablet. Further, a slight step is formed between the hole 8 and the lower inner surface of the input tube 4. Since the surface tri member 12 is provided to remove this step, the discharge tube 6 is not damaged to the tablet 3. Can flow smoothly.

  The tablet 3 that has entered the discharge pipe 6 is supplied to the line 19. When the flow of this line stops, the tablet 3 is clogged in the discharge pipe 6, but the flow stops in a form that leaves the spaces S1 and S2.

  It is assumed that a closing command is input to the valve plate 9 in a state where the tablet 3 is clogged with the input tube 4 and the discharge tube 6. Along with the closing command, the valve plate 9 is driven to rise in the direction of arrow 17 by an air cylinder (not shown). The upper end of the hole 8 comes to the upper closed position 8 (shut). At this time, since the lower end of the hole portion 8 is inserted into the spaces S1 and S2, there is no fear that the tablet 3 will be pushed into the front surface in the traveling direction and the tablet may be broken, and high speed operation is also possible. At this time, the inclination angle θ2 of the valve plate 9 is loose, and the skirt portion 13 is provided below the baffle plate 11, so that certain spaces S1, S2 are provided in front of the valve plate 9 in the direction of travel of the hole portion 8. Is guaranteed.

  Next, it is assumed that the valve plate 9 is shifted from the closed state to the open state. At this time, since the face tri member 12 is arranged and the crossing portion is face-tried, there is no fear that the tablet 3 is caught in the crossing portion, and the valve plate 9 can be operated at high speed in the opening direction.

  The present invention is not limited to the above embodiment, and can be appropriately modified and implemented in various modes without departing from the gist of the present invention.

It is a longitudinal cross-sectional view of the tablet supply apparatus which concerns on one Embodiment of this invention. It is a cross-sectional view shown along the F2-F2 line of FIG. It is a top view of a valve plate.
