Abstract

PROBLEM TO BE SOLVED: To provide a novel adsorption transfer mechanism capable of adsorbing and holding a solid preparation efficiently without using a vacuum pump when transferring the solid preparation into a pocket formed on a conveyance surface while adsorbing and holding the solid preparation.SOLUTION: In a pocket 10 of a rotary drum 11, a suction hole 12 having a suction passage 13 is formed. An adsorption transfer mechanism M has an ejector device 2 that comprises an air inlet 21, an air outlet 22, and a suction port 23 communicating with the inside of a diffusion chamber 20 formed between the air inlet 21 and the air outlet 22. The adsorption transfer mechanism M reduces pressure inside the diffusion chamber 20 and generates negative pressure in the suction port 23 by ejecting compressed air from the air inlet 21 to the air outlet 22. By communicating the suction port 23 with the suction passage 13 and blowing the compressed air to the ejector device 2, the negative pressure is generated in the suction passage 13, and a solid preparation W is absorbed and held in the pocket 10.

Description

  For example, when marking with a laser beam on solid preparations such as tablets and soft capsules, multiple solid preparations can be accommodated and adsorbed in pockets formed on the transport surface, and marking processing can be performed while transporting in this state In many cases, the present invention relates to a novel adsorptive transfer mechanism for a solid preparation in such a case.

For example, solid preparations such as tablets and soft capsules that are widely used for pharmaceuticals and health foods are usually marked with an identification number or symbol such as the manufacturer, drug name, or lot. In order to give a good marking, printing (engraving) using a laser beam has been rapidly spreading in recent years (see, for example, Patent Documents 1 and 2).
In such a case, it is first necessary to accurately position the solid preparation. For example, a plurality of pockets are regularly formed on the transport surface for transferring the solid preparation, and the solid preparation is accommodated and positioned in the pocket. There are many cases. In this state, the solid preparation contained in the pocket is irradiated with a laser beam to give an appropriate marking.

Heretofore, it has been a common technique to apply a vacuum pump to adsorb and hold a solid preparation in a pocket on the transport surface. That is, in this method, a suction hole is formed in the pocket bottom in advance, and this suction hole is connected to a vacuum pump. Then, the vacuum pump is operated to suck in air from the suction hole and directly generate a negative pressure in the pocket to forcibly adsorb the solid preparation into the pocket (see, for example, Patent Documents 3 and 4).
However, the adsorption method using such a vacuum pump has the following problems.
First, since the vacuum tank indispensable for the vacuum pump is large, there is a problem that the entire apparatus becomes large and becomes large equipment. In addition, since a large number of pockets are usually formed, a plurality (large number) of vacuum pumps are required, and there is a problem that a large space (room) for accommodating the vacuum pump itself is separately required.
There was also a problem of noise that the sound when operating the vacuum pump was noisy. Furthermore, the power consumption of the motor when operating the vacuum pump is also a problem.
For this reason, another adsorption transfer mechanism that does not use a vacuum pump has been demanded.

JP-A-5-58025 JP 2008-279060 A JP 2005-35736 A JP-A-7-112164

  The present invention has been made in view of such a background, and when a solid preparation such as a tablet is adsorbed and held in a pocket formed on a conveyance surface and transferred, it is efficiently used without using a vacuum pump. The present invention relates to a novel adsorption transfer mechanism capable of adsorbing and holding.

The adsorption transfer mechanism of the solid preparation is
In an adsorption transfer mechanism that accommodates a solid preparation in a pocket formed on the conveyance surface and conveys the solid preparation while adsorbing the solid preparation in the pocket,
A suction hole is formed in the pocket, and a suction path is connected to the suction hole.
The adsorption transfer mechanism has an ejector device having an air supply port, an exhaust port, and a suction port communicating with the diffusion chamber formed therebetween, and jets compressed air from the air supply port to the exhaust port. In this way, the pressure in the diffusion chamber is reduced to create a negative pressure at the suction port,
The suction port of the ejector device is communicated with the suction channel, and a negative pressure is generated in the suction channel by blowing compressed air into the ejector device, so that the solid preparation is adsorbed and held in the pocket.

  The solid preparation is preferably a tablet.

  Moreover, it is preferable that the pocket which accommodates a solid formulation is formed in the circumferential direction and an axial direction at equal intervals on the outer peripheral surface of a rotating drum.

  The suction path communicating with the suction hole of the pocket is preferably formed such that a plurality of suction paths are branched from one main suction path, and the main suction path is connected to the suction port of the ejector device.

  Moreover, it is preferable that the several suction path formed so that it may branch from the same main suction path is formed in a different size according to the distance from the suction opening of an ejector apparatus.

  Moreover, it is preferable that the receiving guide which makes it easy to receive a solid formulation is formed in a pocket at the upper end inner peripheral side.

  The mechanism for adsorbing and transferring the solid preparation is a structure in which the solid preparation is adsorbed and held in the pocket formed on the transport surface by suction generated by the ejector device without using a vacuum pump. There are no such moving parts, and it can be quiet and miniaturized, and can also save power.

  Further, when the solid preparation adsorbed and held in the pocket is a tablet, the tablet can be reliably adsorbed and held and transferred. In other words, a tablet is usually a formulation in which an active ingredient or an active ingredient added with a shaping material or the like is formed into a fixed shape by a method such as compression molding, and is often formed into a flat shape. Are generally slippery and difficult to align one by one, but even such tablets can be reliably adsorbed and held (aligned) and transported.

  In addition, when the pockets are formed at equal intervals in the circumferential direction and the axial direction on the outer peripheral surface of the rotating drum, many solid preparations can be transferred even on a limited transport surface. Further, the solid preparation draws a circumferential (arc-shaped) conveyance path by the rotation of the rotating drum, and space saving of the entire apparatus can be achieved as compared with the case of transferring on a horizontal plane.

  In addition, if a plurality of suction paths are connected so as to branch from one main suction path, if one main suction path is sucked, suction action is exerted on all suction paths (pockets) connected thereto. And a very reasonable suction mode can be adopted. Specifically, for example, if a suction path acting on a plurality of pockets arranged in the axial direction of the rotating drum is formed so as to branch from one main suction path, if the air is sucked at one end of the rotating drum, the entire area of the drum A suction action can be exerted on (all pockets on the drum).

  Further, when the plurality of suction paths are formed in different sizes according to the distance from the suction port of the ejector device, even if the suction port (pocket) is far from the suction port, the suction is located at a close position. Even in the mouth (pocket), the solid preparation can be adsorbed with substantially the same suction pressure and suction force.

  Further, when the receiving guide is formed on the inner peripheral side of the upper end of the pocket, the solid preparation can be easily received in the pocket, and the solid preparation can be reliably adsorbed and held in the pocket. Further, chipping or breakage when the solid preparation is received in the pocket can be prevented.

They are the perspective view (a) which shows the marking system to which the adsorption transfer mechanism (adsorption transfer mechanism of a solid formulation) of this invention is applied, and explanatory drawing (b) which expands and shows the outline | summary of this adsorption transfer mechanism. It is a front view which shows the marking system to which the adsorption transfer mechanism is applied. The perspective view (a) which shows a suction area setting body and a rotating drum, the explanatory view (b) which shows the modification of the suction groove formed in a suction area setting body, and the perspective view which expands and shows the pocket part of a rotating drum (C).

  The mode for carrying out the present invention includes one described in the following embodiments, and further includes various methods that can be improved within the technical idea.

  The adsorbing and transferring mechanism M (hereinafter simply referred to as “adsorbing and transferring mechanism M”) of the solid preparation of the present invention can be used for a tablet or the like by a negative pressure suction action (so-called ejector action using a venturi effect) generated by an ejector device. It is a great feature that the solid preparation W is transferred while being adsorbed and held in the pocket 10 formed on the conveying surface. In the past, when the solid preparation W was transferred, it was generally adsorbed using a vacuum pump. However, in the present invention, the vacuum pump is not used (the solid preparation W is sucked directly by the vacuum pump). This is a breakthrough.

  Further, the adsorption transfer mechanism M may be used simply as a means for transporting the solid preparation W. For example, if it is used as a transport means for a step of marking the solid preparation W with a manufacturer, a production lot, a drug name, and the like. Is more effective. That is, in this case, the solid preparations W to be marked can be arranged one by one in an accurate and constant posture (a posture suitable for marking), and the marking process can be performed very efficiently. As described above, if the adsorption transfer mechanism M is a transfer means for performing a target work (here, marking) on the solid preparation W, it is more effective, and the target work can be performed very efficiently. . Of course, the target work is not limited to marking.

In the following description, the marking transfer mechanism M to which the suction transfer mechanism M is applied will be described, and the suction transfer mechanism M will be described together.
Further, the solid preparation W will be described mainly by taking tablets as examples, and these tablets are easy to drink by compressing raw materials and ingredients mechanically with a mold or the like in pharmaceuticals or dietary supplements. It is formed into a shape and is also called a tablet. In addition, tablets are generally widely distributed in the form of flat discs, and in this specification, description will be given mainly using disc-shaped tablets. The tablets are given the same symbol “W” as the solid preparation.

As shown in FIG. 1 and FIG. 2 as an example, the marking system S includes an individual conveyance zone Z1 for transferring tablets W supplied in a random state in an appropriate posture one by one, and an appropriate transfer to the tablets W. The marking zone Z2 for performing the marking and the inspection zone Z3 for confirming whether or not the marking has been accurately performed are provided, and the suction transfer mechanism M of the present invention is applied to the individual transport zone Z1.
Hereinafter, each zone will be described.

The individual transport zone Z1 (adsorption transfer mechanism M) is a part that, as described above, aligns tablets W that have a non-uniform posture one by one in an appropriate posture and transports them to the marking zone Z2. In this case, the “appropriate posture” is a posture / position suitable for receiving the marking, for example, a so-called sleeping posture in which one of the tablets W is in contact with the transport surface is common. The marking is applied to the flat surface which is not in contact with the transport surface.
The individual transport zone Z1 adopts a form in which the tablet W is accommodated in the pocket 10 formed on the transport surface, and the tablet W is transported while adsorbing the tablet W in the pocket 10, and the individual transport device 1 mainly contributing to the transport and the tablet And an ejector device 2 that holds W in the pocket 10 by suction.
Hereinafter, the individual conveyance device 1 and the ejector device 2 will be described.

  As shown in FIG. 1 and FIG. 2 as an example, the individual conveying device 1 has a rotating drum 11 forming a conveying surface as a main member, and a large number of recessed pockets 10 are formed on the outer peripheral surface of the rotating drum 11. The tablets W are formed, sucked and accommodated one by one in the pocket 10 and transferred. The rotating drum 11 is held in a cantilevered state with respect to the apparatus base, and the tablet W is conveyed so as to draw an arcuate locus by the rotation of the rotating drum 11.

Further, in this embodiment, the rotating drum 11 is provided in a state in which two drums are paired and circumscribe each other from the vertical direction. Here, when it is desired to distinguish between the two rotating drums 11, the reference numeral "11U" is attached to the rotating drum provided above, and the reference numeral "11D" is assigned to the rotating drum provided below.
Further, the tablets W are transferred from the upper rotary drum 11U to the lower rotary drum 11D, and as shown in FIG. 2, for example, an S-shape is drawn from the upper rotary drum 11U to the lower rotary drum 11D. Are transferred as follows.
In the present embodiment, marking and inspection on the tablet W are performed during the transfer on the upper rotating drum 11U.

  Further, as an example, as shown in FIG. 3A, the pockets 10 formed in the rotating drum 11 are formed in large numbers at equal intervals along the circumferential direction and the axial direction of the rotating drum 11, and both rotating drums 11 </ b> U and 11 </ b> D are formed. Is formed so that the pockets 10 formed in the rotary drums 11U and 11D are aligned with each other so that the tablets W can be smoothly transferred (replaced) from the upper rotary drum 11U to the lower rotary drum 11D. It has become.

Further, since the tablets W are transported while being attracted to the pockets 10 of the rotary drum 11, suction holes 12 are formed on the inner bottom portion of the pockets 10 as shown in FIGS. 1B and 3C as an example. The suction hole 12 is connected to a suction path 13 extending toward the center of the rotary drum 11 (this suction path 13 acts on each pocket 10 to the last).
Furthermore, in this embodiment, the plurality of pockets 10 (referred to as “pockets on the same axis”) arranged in the axial direction (the axial direction of the rotating drum 11) on the outer peripheral surface of the rotating drum 11. The suction path 13 of the pocket 10 is connected to the same main suction path 14 so that the suction action is applied to the pockets 10 on the same axis at once (at the same time). As described above, the suction passages 13 of the respective pockets 10 are connected to the main suction passage 14 in a lump that acts on the pockets 10 on the same axis.

Next, a configuration in which the suction action acting on the pocket 10 on the same axis acts only in an appropriate angle range (section) of the rotary drum 11 (a configuration in which the suction action is terminated halfway for smooth delivery of the tablet W). Will be described.
For example, as shown in FIG. 3A, a suction area setting body 15 that does not rotate is provided at the support side end of the rotating drum 11, and the rotating drum 11 slides on the suction area setting body 15. Rotate while. In addition, for this reason, the suction area setting body 15 is preferably provided with a Teflon (registered trademark) coating or the like on the surface in order to improve the slidability.
Further, the suction area setting body 15 is formed with an arc-shaped suction groove 15V formed on the sliding surface with the rotary drum 11, and pipe connection is made so that suction by the ejector device 2 acts on the suction groove 15V. (A suction pipe 23P described later is connected).
As a result, the suction action is applied to the pocket 10 only in the section where the main suction path 14 of the rotary drum 11 communicates with the suction groove 15V.

  As shown in FIG. 3A, the suction groove 15V may be continuously formed in an angle range (area) where suction is performed, but may be intermittently formed. That is, once the tablet W is adsorbed and held in the pocket 10 by the suction action, the tablet W acts to block the suction hole 12, and even if the supply of compressed air in the ejector device 2 is stopped halfway, the pocket 10 (suction Since the degree of vacuum of the channel 13) can be maintained, for example, as shown in FIG. 3B, the suction groove 15V can be formed in a divided state. Incidentally, in FIG. 3B, the ejector device 2 is required by the number of the divided suction grooves 15V (a plurality of ejector devices are required). For this reason, for example, it is desired to maintain the suction force (strong suction force) in the suction area. In some cases, the suction groove 15V can be divided and formed.

Further, in FIG. 3B, the suction pipe 23P is shown connected to only one central portion of each suction groove 15V, but the connection position and number of the suction pipes 23P with respect to each suction groove 15V are changed as appropriate. Is possible. For example, since the weight of the tablet W acts as a drop-off action from the rotary drum 11 (of course, the suction action is set to be superior) on the lower outer periphery of the upper rotary drum 11U, the connection position of the suction pipe 23P is set at this portion. It is possible to increase. In consideration of this, it is also possible to separately provide a member for guarding the outer peripheral side of the drum at the lower portion of the upper rotating drum 11U, thereby reliably preventing the tablets W from falling off the rotating drum 11. is there.
The suction area setting body 15 is provided separately for the upper and lower rotating drums. When it is desired to distinguish the upper and lower rotating drums, the suction area setting body 15 is distinguished by the suffixes “U” and “D” as with the rotating drums 11U and 11D. .

Moreover, it is preferable that a receiving guide 10G (so-called chamfering) such as an inclined surface or an R surface is formed on the inner peripheral side of the upper end of the pocket 10, for example, as shown in FIG. Thereby, it becomes easy to accommodate the tablet W in the pocket 10, and the tablet W can be more reliably accommodated in a more correct posture. Moreover, the impact applied to the tablet W when it is accommodated in the pocket 10 can be suppressed, and damage (chip) of the tablet W can be prevented.
Further, below the lower rotating drum 11D (rear stage), for example, as shown in FIG. 2, the conveyor C or the like as a transfer device that receives the tablet W that has been inspected and sends it to another process (for example, a container filling process). Is preferably provided.

On the other hand, an individual supply mechanism N for supplying tablets W to the pockets 10 of the upper rotary drum 11U one by one is provided above the pair of rotary drums 11.
This individual supply mechanism N always supplies the tablet W to the pocket 10 of the upper rotary drum 11U in the same posture and reliably delivers it, and supplies the outer periphery of the upper rotary drum 11U obliquely above the upper rotary drum 11U. The drum 17 is a main member, and the supply drum 17 is also formed with a pocket. This pocket is substantially the same pocket as the rotating drum 11, but the tablet W is transferred without being adsorbed and held in the pocket.
The supply drum 17 is preferably provided with a Teflon (registered trademark) coating or the like on the surface, for example, so that the tablet 10 can be easily transferred to the upper rotating drum 11U (improvement of detachability).

  Further, a shooter 18 is provided above the supply drum 17, and this shooter 18 is formed in a cylindrical shape that allows, for example, the tablet W to pass therethrough, thereby aligning the tablets W in series (one tablet W). By aligning the flat surface in contact with the bottom surface of the shooter and sliding in this state, the tablets W are sequentially fed (dropped) into the pockets arranged on the same circumference of the supply drum 17. For this reason, the same number of the shooters 18 of the present embodiment as the rows of the pockets 10 (circumferential rows) arranged on the same circumference of the rotary drum 11 are formed.

  Furthermore, a hopper 19 for temporarily storing a large number of tablets W is provided above the shooter 18. Although the tablets W are charged into the hopper 19 in a random state, the tablets W are supplied to the shooter 18 little by little by giving vibration to the hopper 19, for example. In addition, the tablet W is dropped and supplied to the shooter 18 without causing a bridging phenomenon in the hopper 19 by this vibration.

Next, the ejector device 2 will be described.
The ejector device 2 is a device as a drive source that causes a suction action in the pocket 10 of the rotary drum 11, and the basic structure is an air supply port 21 and an exhaust port 22 as shown in FIG. And a suction port 23 communicating with a chamber (this is referred to as a diffusion chamber 20) formed between them, and jetting compressed air from the air supply port 21 to the exhaust port 22 (by a high-speed flow of compressed air) A device that lowers the pressure in the diffusion chamber 20 and generates a negative pressure (vacuum) at the suction port 23 (a so-called Venturi effect, which is also referred to as an ejector action in this specification).
Here, a pipe that is connected to the air supply port 21 and blows compressed air into the diffusion chamber 20 at a high speed is an inflow pipe (nozzle) 21P, and a pipe that is connected to the exhaust port 22 and discharges the compressed air from the diffusion chamber 20 is a discharge pipe (diffuser). ) 22P, and a tube connected to the suction port 23 for exerting a suction action (ejector action) by the negative pressure on the pocket 10 is a suction pipe 23P.
The discharge pipe 22P discharges the air sucked through the suction pipe 23P by mixing with the compressed air blown from the inflow pipe 21P, and only the compressed air blown from the inflow pipe 21P is discharged. Not. Incidentally, as such an ejector apparatus 2, an apparatus disclosed in Japanese Utility Model Laid-Open No. 6-63900 can be applied as an example.

Next, the marking zone Z2 will be described.
The marking zone Z2 is a part where an appropriate marking is applied to each tablet W transferred by the upper rotating drum 11U. In this embodiment, a marking is applied by irradiating a laser beam on the flat surface of the tablet W. It is. For this reason, the main member acting on the marking zone Z2 is the laser marker 31. The marking on the tablet W is not limited to such a laser beam irradiation method (laser marker 31), and for example, printing with ink attached is also possible. Instead of the laser marker 31, a printing apparatus for attaching ink is applied.
Further, the work performed while the tablets W are sucked and transferred is not necessarily limited to the marking work.

Next, the inspection zone Z3 will be described.
The inspection zone Z3 is a part for inspecting whether or not the marking applied to the tablet W has been correctly performed, and the CCD camera 41 that images the surface (marking surface) of the tablet W is a main component. Reference numeral 42 in the figure is a monitor that displays the screen of the imaged tablet W, and reference numeral 43 in the figure is a slit for narrowing down the tablets W reflected on the monitor 42 and clarifying the tablets W to be inspected. .
The inspection here is mainly to check whether or not the marking is properly performed. In combination with such a check, such as the color or chipping of the tablet W or foreign matter contamination (black spots). It is also possible to inspect for defects.

The marking system S to which the suction transfer mechanism M of the present invention is applied has the basic structure as described above. Hereinafter, the tablet W is sucked on the transport surface (the rotating drum 11) while explaining the operation mode. The aspect to hold | maintain is also demonstrated collectively.
First, a plurality (large number) of tablets W are put into the hopper 19. Of course, the tablets W at this time are in a random state and take a disjointed posture.
Then, by applying vibration or the like to the hopper 19, the tablets W are sent (supplied) to the shooter 18 little by little and are put into the shooter 18 in an appropriate posture. The tablets W are aligned in a row with the above posture by passing and sliding down in the shooters 18.
Thereafter, the tablets W in such a posture are fed (delivered) one by one from the shooter 18 into the pocket of the supply drum 17.
The tablets W fed into the supply drum 17 are transferred along the lower periphery of the supply drum 17. Since the supply drum 17 has no suction mechanism, the tablet W stored in the pocket falls (drops out) as it is, but in this embodiment, as shown in FIG. Since the covering dropout prevention guide 17G is provided, there is no possibility that the tablet W will fall from the supply drum 17.

Thereafter, the tablet W is transferred from the supply drum 17 to the upper rotating drum 11U. At this time, the ejector device 2 is operated in advance, and the negative pressure suction action by the ejector device 2 is applied to the suction pipe 23P, It exerts on the pocket 10 through the main suction path 14, the suction path 13, and the suction hole 12. As a result, the tablets W are reliably and smoothly transferred from the supply drum 17 to the pockets 10 of the upper rotary drum 11U.
In this embodiment, since the receiving guide 10G is formed on the inner peripheral side of the upper end of the pocket 10, when the tablet W is transferred (accommodated in the pocket P), the tablet W is placed in a more correct posture and more reliably. 10 can be accommodated. In addition, breakage (chips) of the tablet W during storage can be prevented.
Further, the tablet W receives the marking by the laser marker 31 during the transfer by the upper rotating drum 11U, that is, in an appropriate posture (with the flat surface facing the open outer peripheral side) accommodated in the pocket 10, and thereafter Although inspection (imaging) is also performed by the CCD camera 41, the tablet W is accurately positioned because it is sucked and held in the pocket 10, and these can be precisely performed.
Thereafter, the tablets W that have been inspected are transferred from the upper rotary drum 11U to the lower rotary drum 11D, and further transferred from the lower rotary drum 11D to the conveyor C, and transferred to, for example, a filling process.

[Other Examples]
The present invention has the above-described embodiment as one basic technical idea, but the following modifications can be considered.
First, in the above description, the tablet W is exemplified as a kind of the solid preparation W. However, as the solid preparation W, soft capsules or the like can be applied.
In addition, the individual conveying device 1 (as a conveying surface including the suction transfer mechanism M) is not limited to the rotary drum 11, and it is also possible to apply a conveyor or the like in which the conveying surface forms a flat surface. .
Furthermore, since the major feature of the present invention is the suction transfer mechanism M for transporting the tablets W, in the above description, the tablets W determined to be defective as a result of imaging (mainly defective marking here) are positively considered. However, the configuration for removing from the non-defective product is not described, but a signal is sent to the upper rotary drum 11U based on, for example, the image on the monitor 42, and the defective tablet W is removed without being transferred to the lower rotary drum 11D. It is possible to add structure.

In FIG. 1B, all the suction paths 13 acting on the pocket 10 (the same main suction path 14) on the same axis are drawn with substantially the same size, but the sizes can be different. is there. For example, it is possible to vary the size of the suction path 13 according to the distance from the suction port 23 of the ejector device 2 (for example, the farther one is made larger).
Further, in FIG. 1B, the main suction path 14 is drawn with almost the same size regardless of the distance from the suction port 23 of the ejector device 2, but depending on the distance from the suction port 23. The diameter size can be varied (for example, the diameter is gradually increased as the distance from the suction port 23 increases).

  In addition, when it is desired to form the rotating drum 11 long in the axial direction, the rotating drum 11 is configured by connecting a plurality of drum bodies that are divided in advance in the axial direction so as to extend in the axial direction. Is possible. When the rotary drum 11 is formed in the axial direction as described above, the laser marker 31 and the CCD camera 41 (slit 43) are naturally formed in a length corresponding to this.
