The present invention relates to an apparatus for calibrating an irregularly arranged capsule so that the cap is uniformly arranged at high speed, and is an improved version of the capsule calibrating apparatus shown in US Patent No. 3,756,402.

The capsules are inserted into the capsule body, and they must be assembled together while being treated as empty capsules, but they must be easily disassembled when filling the medicine. It should be arranged uniformly with the end facing forward. In particular, it is preferable that the cap is arranged to face forward, and since the capsule manufacturing apparatus produces 600 to 1,200 capsules per minute, it should be arranged quickly.

In a conventional apparatus, a capsule conveyor consists of a number of buckets in which relatively narrow and long cavities are perforated, the upper part of each cavity being adapted to easily insert a new capsule. On the other hand, since the bottom has a pair of ribs, it forms a calibration groove through which the capsule body passes but not the cap. The capsule is thus supported by the bottom supporting a rail of constant height on which the bagets are perturbed.

In addition, in the calibration zone, the rail is provided with grooves and protrusions for inducing air flow downward, so that when the capsule passes through the protrusions of the rail, the capsule facing forward is inclined vertically near the bottom of the main body. Protrudes under the bagets of the conveyor. At this time, the upright capsule is further inclined forward by the upper brush, and is rapidly moved downward, and is reloaded into the cavity of the conveyor by an inclined valve, and the capsule is falling out of the conveyor because there is an upper plate. Is prevented. In the present invention, the upper brush, the lower belt and the upper plate are removed in the conventional apparatus, but the capsule can be arranged at high speed without damaging the capsule.

In the present invention, the capsule is loaded in an irregularly arranged state in a plurality of deep and long cavities in the conveyor, the conveyor is also composed of a plurality of bagets connected to the chain (chain), the upper portion of each hole and the conventional conveyor through Similarly, the depth is approximately equal to the diameter of the capsule, while the length and width are such that the capsule can be easily inserted therein. On the other hand, there is a pair of protrusions on the upper part of the cavity to allow the capsule body to pass through, but not the cap, to form a calibration or the like, while below the protrusions there is a width and depth that can accommodate the full length of the upright capsule body. A deep lower portion is formed, wherein the end of the cap is supported by the protrusion.

Since the narrow cam track extends on both sides of the conveyor, a central track and a longitudinal track groove are formed, and the cam track is conveyed by the perturbation track where the bagets are perturbed when the conveyor is moved. On the other hand, the cam track is narrower than the cavity, and together with the cavity is intended to induce air flow along the sidewalls between the inlets in the perturbation track, so that the capsule can be loaded or held, and the upper end of the cam track can be Will be supported.

In the calibration zone, the cam tracks are tilted upwards by raising the capsules supported by the projections on the side.

At the position where the cam track is sharply terminated at the upper boundary point of the suction passage, suction force sucks air downward through the cavity.When the capsule facing forward passes the boundary point, the rear end of the capsule is supported by the cam track. On the other hand, the front end would be exposed to the air flow through the cavity without being supported. Thus, the capsule will lean sharply around the boundary point, while the body will pass between the protrusions.

At this time, since the capsule is inclined at the raised position, the side end of the capsule cap will be greatly inclined before contacting the projection of the cavity. Also, when the end of the capsule is in contact with the projection, the end of the cap is slightly sandwiched between the projections, so that a contact point is formed between the cap and the projection. The capsule is therefore pivotally supported by the protrusion at the point of contact and inclined more around the point of contact, but is prevented from sliding backwards in the cavity along the protrusion.

The conveyor is inclined 45 ° upwards, and the airflow induced from below through the cavities and cavities between the protrusions, as described above, causes each capsule to stand up and at the same time tilts forward against the inclined conveyor, The capsule is held in the middle of the cavity. Thereafter, the capsule is conveyed upwards on the second cam track inclined by the conveyor, and since the cam protrusion is located at the rear of the second cam track, the capsule which is in contact with the lower end of the capsule main body is inclined forward more, and at the same time, Since the second cam track has a cam surface, the lower end of the inclined capsule is raised to reverse the cap to the front at the top of the cavity. At this time, the lower end of the capsule is in contact with the rear of the lower portion of the cavity, by the rear of the capsule is inclined forward, and at the same time tilted upward by the cam track. If the capsule is slid back to the rear of the cavity, it will be raised along the rear by the cam track and tilted forward, and there is no fear of the capsule being sandwiched between parts because the air is continuously flowing downward.

Such a corrective action is not only very efficient, but also the corrective action is assured even without the upper brush and the lower belt used in the conventional apparatus. When the present invention as described in detail by the accompanying drawings as follows.

The device shown in the figure is a device for arranging the capsule 5 in which the main body 6 and the cap 7 shown in FIG. 2 are assembled together evenly with the cap facing forward.

The device according to the invention has a housing having a drive in the compartment 12 at the bottom and a housing for supporting the upper and lower shafts 14 and 16 on which the sprockets 18 and 20 are installed. 10, the side chain of the conveyor 22 is wound around the sprocket. On the other hand, the upper operating range of the conveyor is inclined upward by 45 ° from the lower sprocket 20 through the loading area below the hopper 24 to the calibration region 26 and the upper sprocket 18. The upper sprocket is part of the transfer wheel 25 for transferring the capsule from the conveyor to the test head 28, the test head 28 is installed at the discharge point opposite the transfer wheel, such a test head ( 28 is described in detail in the aforementioned US Pat. No. 3,756,402.

[Conveyor]

As shown in FIGS. 2 and 3, the chain conveyor consists of a pair of chains 30 and 32 parallel to each other at regular intervals, while each chain is composed of a plurality of pin links or roller links. Conveyor bagets 34 are supported between the chains. On the other hand, each baget has an upper body 36 having an outer edge 38 in which a pinhole 40 is drilled, and after the inner end of the pin 31 of the chain is inserted into the pinhole 40, a snap ring is inserted. ring 42). Each baget 34 also has a central portion 44 having a flat bottom surface that can be installed on a support orbit. Thus, the conveyor is configured by the fact that a plurality of adjacent bagets 34 are connected in series.

At the center of each baget is a longitudinal cavity 46 with sidewalls parallel but rounded at its ends, the top of which can be loosely inserted so that one capsule 5 faces forward with respect to the conveying direction. . Further, downwards from the upper surface of the bagets, projections 48 are formed on the sidewalls of the cavities 46 so that the orthodontic grooves 50 are formed downward, in particular, the main body 6 of the capsule is between the projections and the fourth. As shown by the dotted lines in the figure, the width between the protrusions is determined to pass through the calibration groove. Therefore, the cap 7 is held by the protrusion so as not to pass through the calibration groove 50.

The baget according to the present invention is distinguished from the baget shown in US Pat. No. 3,756,402 in the following points. In other words, the main body 36 of the bagets according to the present invention is characterized in that the capsule body 7 is formed from the protrusions 48 when the end of the capsule cap 7 is supported between the protrusions 48 as shown by the dotted lines in FIG. It has a central portion 44 protruding downward by a distance substantially equal to the protruding length of 6). Thus, although the lower end of the capsule body is always accommodated in the capsule cavity, there is no fear of damaging from below.

While the bagets 34 are transported in the upper operating range, they are supported by a downward bagets supporting perturbation track 54, as shown in FIGS. 6 and 3, wherein the perturbations are the central portion of the bagets ( 44) It has a flat top surface which perturbably supports the bottom surface. On the other hand, since each baget has a central groove 52, it is possible to accommodate the center cam track 56 which is conveyed by the perturbation track 54. Also, in the loading zone, since the plurality of cavities 58 are perforated in the center where the cam track 56 passes, the cavity 46 and the perturbation track 54 of the baget 34 are installed. A cavity is formed in the side piece so that the suction chamber 61 may penetrate in the lower suction manifold 60. Therefore, the suction chamber 61 is formed over the entire length of the conveyor below the hopper 24.

[Loading]

Conveyor loading mechanisms are shown in FIGS. 1 and 5, wherein the sidewalls 62 of the hopper are installed in a support block 64 carried by a frame of the apparatus of the present invention, A channel for conveying the conveyor basket is formed at the inner bottom end. In addition, the bagets are supported on the surface of the perturbation track 54 positioned between the chains 30 and 32, while the semi-cylindrical grooves in which the pair of rolls 66 are inserted are formed in the immediately upper block 64 of the bagets. The roll 66 is substantially in contact with the inner surface of the hopper side wall 62, and a feed groove 68 is formed between the rolls 66 directed to the cavity 46 in the baget 34. On the other hand, both ends of the roll 66 are installed in the bearing (bearing) to rotate in the opposite direction, since the surface of the roll forming the supply groove is moved upward, the misaligned capsule is removed from the supply groove. It is also preferable that the surface of the roll is a friction surface such as rubber, and the central cavity 58 and the supply groove 68 penetrated with the conveyor cavity on both sides of the cam track 56 by the vacuum force in the manifold 60. While the air flow is induced downwardly through, the perturbation trajectory 54 is close to the bottom of the conveyor cavity, except when it penetrates the central cavity 58.

The capsule in the hopper 24 is vibrated by a diaphragm 70 installed on the back wall 63 of the hopper, which is made of plastic material and the upper end is fixed to the back wall 63 while in a position adjacent to the lower end. It is connected to a piston rod 72 of an air cylinder 74. On the other hand, the air cylinder is connected to the air valve 78 by air pipes 75 and 76, the air valve 78 has an air suction pipe 79, the shaft 16 of the lower sprocket 20 The cam driven lever 80, which is driven by the cam 82 provided on the side, is operated. In addition, when the sprocket and the conveyor are driven, the air valve 78 supplies air to the air cylinder to rapidly vibrate the diaphragm 70, so that the capsule of the hopper is loaded into the conveyor cavity through the supply groove 68. As much flow as possible.

A plurality of needles 84 are provided in the support rod 86 in the center of the hopper 24 to remove the other capsule after the capsule is filled in the conveyor cavity, or to prevent the insertion of only two ends or two of the capsules into the holes. Since the pivot is installed, the lower end of the needle projects below the supply groove 68 between the rolls 66. In addition, the needle 84 is under the action of the spring downward, but as shown in the dashed line in Figure 1 can move upwardly elastically.

In the loading mechanism, since the vacuum force acts continuously on the suction chamber 61, the feed groove 68, the cavity 46 of the conveyor bagets, the side of the cam track 56, and the perturbation track 54 downward from the hopper. Air is sucked into the cavity 58 at the. On the other hand, the capsule in the hopper 24 is continuously vibrated by the vibration of the diaphragm 70, the roll 66 is rotated continuously in the direction of the arrow, so that the capsules misaligned with respect to the supply groove 68 is in the supply groove Deviates far. The capsule will then be received into the cavity 46 of the conveyor bagets through the feed groove, if properly arranged with respect to the feed groove, by gravity and air drawn into the feed groove 68. Once the cavity is filled, the needle 84 removes other capsules that tend to be transported with the filled baget, and if one or more capsules are inserted upright into the conveyor cavity 46, the needle 84 Return the same upright capsule into the hopper. The capsule once loaded into the cavity will also be maintained by the air flow and conveyed upwards. Therefore, the inclination and the elastic action of the needle 84, and the vibration by the diaphragm 70 to the top of the conveyor to make a plurality of capsules in the hopper flow state, it is possible to fill the capsule at the conveyor cavity speed.

[Fixed action]

When the capsule is loaded into the conveyor cavity as described above, the capsules are arranged irregularly. That is, some capsules will face forward while others will face forward. However, it is desirable for all capsules to be arranged so that the cap is directed forward uniformly.

The instrument of the calibration zone 26 is shown at 7 to 10 degrees, while the conveyor perturbation track 54 slopes upward 45 ° to reach the calibration zone, while the vacuum chamber 61 ends in front of the calibration tool, No vacuum force is applied to the capsules in the basket. In addition, a vacuum manifold 90 separated below the perturbation trajectory 54 is disposed in the calibration zone, and a vertical calibration cavity 94 is cut in the center in the perturbation trajectory 54 above the vacuum chamber 92. The cam track 56 extends continuously from the loading zone to the calibration cavity 94, and the projection 96 and the flat part 98 protrude upward slightly on the upper surface of the cam track 56 immediately in front of the calibration cavity 94. At the front end of the flat section 98, the cam track ends at the boundary point 100, where the cam track is cut at an angle of about 105 ° to form a projection, which is about 30 downward from horizontal. Incline by ° The protrusions are shortly projected, and it is preferable to project shorter than the height at which the cam tracks 56 are exposed above the perturbation tracks 54, while the cam tracks below the projections coincide with the vertical side of the calibration cavity 94. 102 is cut to form.

The width of the orthodontic cavity 94 is such that the capsule can be inverted to stand upright as it passes through the cavity, but the partially inclined capsule is quickly brought back into contact by the cam mechanism while inclined. On the other hand, past the calibration cavity 94, the front end portion of the perturbation trajectory 54 is to convey the second cam track 106, the second cam track is a projection projecting to the correction cavity 94 in the rear ( 108), the steep inclined end protrudes backwards to prevent the capsule from tipping forward. In addition, above the abrupt inclined end portion, the second cam track 106 is a flat portion protruding to the tip of the cam track 106 adjacent to the conveying wheel 25 and the gentle inclined cam surface 110 protruding more than the conveyor baget length. 112).

Along the second cam track 106, there are a number of cavities 59, which penetrate the vacuum chamber 105 below the subleave track 54, so that when the conveyor passes through the second cam track 106, the conveyor By keeping the air downward through the cavity, it not only assists in corrective action, but also keeps the calibrated capsule in the conveyor. The capsule is also held in the cavity by a downward flow of air that is led through the colonel and conveyor cavity 46 to the cavity 58 in the perturbation path 54. On the other hand, when the bagetz passes through the calibration zone, the downward flow of air is stopped until the capsule reaches the calibration cavity 94, but when it reaches the calibration cavity 94, the capsule is a projection 96 of the cam track 56 It is lifted upward by the support and is supported by the protruding flat part 98 as shown in FIG. At this time, since the capsule 5a is supported by the protruding flat portion 98 of the cam track 56, the side portion of the capsule is separated from the protrusion 48 on the side wall of the cavity 46. Thus, when the capsule passes through the boundary point 100 at the end of the cam track 56, the front end of the capsule is exposed to the air flow flowing downwardly through the protrusion into the calibration cavity 94. The capsule 5b shown in FIG. 9 is transported past the boundary point 100, and because of the gravity and downward airflow, the capsule is like the capsule 5c shown in FIG. 7, 9 around the boundary point 100. Inclined In addition, as described above, since the capsule is lifted upward, the side of the capsule is separated from the protrusion 48, and the capsule obtains a slight momentum before the cap 7 is contacted with the protrusion 48. At the same time, since the opening side end of the cap 7 is a circular section, the opening side end of the cap 7 is pinched like a wedge between the protrusions 48 when in contact with the protrusion. Thus, the contact point between the side of the cap 7 and the protrusion 48 becomes the pivot contact point 114. Because of the wedge-like action described above and the fever contact point 114, the capsule does not slide backwards along the protrusion of the baget which is conveyed forward, and the capsule is more inclined around the fever contact point 114, and the correction cavity ( Since air flows downward through 94, the capsule is inclined forward with respect to the conveyor, like the capsule 5d shown in FIGS. 7 and 9.

When the conveyor continuously conveys the capsule forward, the lower end of the capsule is in contact with the second cam track 106. If the capsule is not sufficiently inclined forward, the lower end of the capsule protrudes backwards and the ninth portion of the capsule. Contact is made like the capsule 5e shown in FIG. Thus, the capsule is more inclined forward, and the gently inclined cam protrusion 110 is in contact with the capsule, further inclining the cap toward the front. The capsule is then conveyed along the cam protrusion 110 toward the cam flat 112, whereby the capsule is in the position of 5h shown in FIG. 7 via the positions of 5f and 5g.

When the capsule is slipped and positioned as shown in dashed lines in FIG. 4 to the rear of the cavity, the end of the capsule body is fully received in the deep bottom or groove 50 of the cavity and is upright in the cavity, in front of the upright capsule. When conveyed, the lower end of the capsule is inclined forward while contacting the cam surface of the second cam track and raised upward, and air flows downward by suction force through the cavity 59 at the front end of the track 54. Therefore, the capsule is sucked forward so that the cam is arranged forward.

When the capsule is transported through the calibration zone, the capsule with the cap already forward will not be reversed, and when the capsule with the cap forward reaches the position of the capsule 5b shown in FIG. Air will tilt the capsule around the boundary point 100. At this time, since the front end of the capsule cap is in contact with the protrusion 48 of the conveyor cavity, the capsule will not be tilted any more, and when passing through the boundary point 100, the air flowing downward tilts the capsule end downward, but As described above, the second cam track 106 is calibrated.

Since the above-mentioned corrective action is carried out with the rapid conveyance of the conveyor and capsule, it is not certain what happened and whether the above described wedge-like action occurs. However, the capsule does not slide backwards in the hole of the baget, and when the conveyor is stopped in the middle of the calibration zone, the capsule does not slide backwards because it is pivotally supported in the baget.

The wedge-like action described above deforms the middle of the capsule, where the circular opening side end of the cap 7 is slightly flattened in the shape of an egg, and the capsule is usually easily subjected to such buckling.

As described above, the capsule straightening device according to the present invention certainly not only reverses the cap to face forward, but also can process the capsule produced at about 600 to 900 in one minute at high speed. At the same time, in the calibration operation according to the present invention, the capsule is not caught and damaged, and the brush and belt in the apparatus of US Pat. No. 3,756,402 are not necessary.

This calibration device is also effective for removing capsule debris from the conveyor. If the conveyor bagets contain only one capsule body or capsule debris, such a body and debris may be transferred through a cavity (94) into a vacuum chamber ( 92), and will accumulate in a box (not shown).

When the conveyor bagets leave the calibration zone shown in Figs. 7, 9, all the capsules contained in the holes will be transferred to the transfer wheel 25 with the caps arranged forward, and it is not necessary for all of the bagets cavity to be filled with capsules. However, the conveying speed of the conveyor is preferably higher than the speed at which the capsule is supplied from the hopper (24).

On the other hand, in the above embodiment, the calibration mechanism has a conveyor that is tilted upward by about 45 °, but may be arranged differently.

[Transportation mechanism]

The conveying wheel 25 shown in FIGS. 11 and 12 consists of an assembly comprising two sprockets 18a and 18b on which the conveyor chains 30 and 32 are wound, the sprocket having a pair of rings ( 118 and 120 are assembled to face each other, and the circumferential ring 122 projects between the edges 38 of the conveyor bagets 34 so that the central portion 44 of the bagets is supported on the other surface. In addition, the two sprockets 18a and 18b and the rings 118 and 120 are fastened by bolts to form a single rotor, which is hollow with a passage 164 in the center. It has an outer hub 124 mounted and driven on the shaft 126. On the other hand, the end cap 126 in the hub 124 seals the end of the hollow side, while the shaft is rotatably installed in the ball bearing 130 installed in the hollow fixing hub 132, the rotor is fixed hub ( Supported by a ball bearing 134 between 132 and inner sprocket 18b. The cam 136 is installed in the small diameter of the fixed hub 132, and is sealed by the O-ring 138 for the ring 120, the fixed hub 132 is a ring that can be rotated when adjusting ( 142 is installed on the opposite side of the mounting plate 140.

The conveying head consists of a plurality of plungers 144, which are formed between the two rings 118 and 120, in the perturbation 146 which is arranged in the center of the rim 122. In addition, the inner end of each plunger 144 has a cam follower boss 148 projecting laterally, and is inserted into the cam groove 150 formed in the cam 136. Therefore, the cam follower and the plunger 144 are accurately driven inward and outward according to the formation of the cam groove 150.

A concave capsule sheet 152 is formed at an outer end of the plunger 144, and the capsule sheet is formed at the inner end of the plunger concentrically with the cam driven boss portion 148 by the air passage 154. It is connected with the side cavity 156. There is also a transverse cavity 155 in the middle of the air passage 154, which is located between the sides of the perturbation 146 but is closed by the sides. Accordingly, the side cavity 156 of the air passage penetrates normally with the vacuum chamber 160 in the ring 118, and is connected to the inner passage 164 of the shaft 126 through the cavity 162 to be connected to the vacuum tank. (Not shown).

The hollow shaft 126 driven by power drives the conveyor 22 through the sprockets 18a and 18b, and at the same time, the lower sprocket 20 supporting the lower end of the conveyor is an air control cam 82. ). Meanwhile, the transfer wheel 25 and the conveyor are driven in an appropriate relationship with the test head 28, and a detailed description of the test head is described in US Pat. No. 3,756,402, in which the test head receives a capsule transferred from the transport wheel. It is composed of a plurality of rollers 170 that can be formed grooves, the transfer head is provided with an internal suction passage to maintain the capsule in the grooves between the rollers 170.

The plunger 144 on the transfer wheel is shown in FIG. 11, since normally the suction chamber 160 penetrates through the cavity 156 through the air passage 154 in the plunger, thus allowing air into the capsule sheet 152. Is aspirated and the capsule is retained on the capsule sheet when the plunger is conveyed. As shown in FIG. 11, the front end of the second cam track 106 of the conveyor protrudes into a contact formed in the conveying path of the capsule sheet 152 at the outer end of the plunger 144, and the plunger ( Since the 144 is retracted, the conveyor baget 36 is supported by the plunger while the baget cavity 46 coincides with the plunger. Accordingly, the cam follower 148 of the plunger 144 is lifted upward by the cam protrusion 171, and the capsule sheet 152 at the end of the plunger is transferred by the baget like the capsule 5i shown in FIG. 11. In contact with the capsule 5, the capsule in the basket cavity 46 is supported by the sheet 152 of the plunger by vacuum force. As the feed wheel rotates, the capsule is moved from the 5i position shown in FIG. 11 to the 5k position. When the plunger reaches the opposite side of the inspection head roller 170, the cam protrusion 172 is placed in the cam groove 150. Since it is formed, the angular plunger 144 is gradually raised to the conveying position, and the capsule 5m is disposed in the groove between the pair of rollers 170. On the other hand, when the plunger reaches the conveying position, the axial cavity 158 in the plunger is moved outward beyond the walls of the rings 118 and 120 as shown on the left in FIG. And the suction force acting on the capsule sheet 152 is stopped, the capsule 5m is released to be transferred to the test wheel, and the suction force acting on the test wheel transfers the capsule to the test wheel.

[work]

The capsules are fed from the maker to the hopper 24 and are vibrated by the diaphragm 70, where only the capsules matched with the feed grooves are transported to the conveyor apart between the rolls 66 and in the cavity 58 in the perturbation track 54. It is loaded into the cavity 46 of the bagets 34 by the air flow through).

The capsule in the basket cavity 46 is loosely received between the upper side wall and the end wall, and is supported by the cam track 56 below, and is received in an irregularly arranged state when loaded into the cavity from the hopper. After the conveyor is transferred from the loading zone to the calibration zone, shown in detail in the seventh to tenth degree, the body reverses the forward facing capsule by the aforementioned "calibration". The calibration cavity also removes the separated body or debris from the conveyor and transfers it to the accumulation box through the bottom hole of the baget.

The capsules accommodated in the conveyor cavity passing through the calibration zone are all transferred to the transfer wheels shown in FIGS. 11 and 12 after the caps are facing forward. On the other hand, the plunger 144 provided inwardly on the conveyance wheel to which the conveyor is conveyed rotates at the same speed as the baget, so that it is consistent with the baget cavity. Also, since the plunger protrudes outward from the bottom of the hole, the capsule is supported by the vacuum force on the capsule sheet 152 of the plunger 144, and when the conveying position shown in the left side of FIG. Since the vacuum force supporting the capsule 5 leaks to the atmosphere through the side cavity 158, the capsule is transferred to the test head 28.

When the capsule reaches the calibration zone, the capsule is supported by the narrow cam track 56 at the center while being lifted above the lower protrusion 48 of the conveyor baget, so that the capsule is before the side contact with the protrusion of the batter, It can be tilted greatly around the boundary point 100.

When contacted as described above, two contact points 114 are formed so that the sides of the capsule cap 7 are pinched like wedges between the projections 48 and do not slide backwards in the bagets cavity 46, and the capsule Is further inclined around the pivot point 114, which is the midpoint of the cavity. The capsule is then erected in space due to the air being sucked downwards, tilted forward with respect to the conveyor, and further transported causes the lower end of the body 6 to contact the second cam track 106. At this time, since the second cam track has a protrusion 108 and an inclined portion 110, the cap of the capsule is further inclined to face forward. However, when the cap is already loaded, the capsule with the cap forwarded is not inverted, because the cap front end is in contact with the projection 48, so that the capsule does not tilt even if it is transported past the calibration zone.
