Non-Adsorption Roller Transfer Unit (10)

First, referring to Figures 1 to 5, looks at the non-adsorbing roller transfer unit 10. In the non-adsorption roller conveying unit 10, a plurality of rollers 11 are continuously arranged along the circumference while maintaining a gap. In addition, the non-adsorption roller conveying unit 10 is rotated to place the goods to be injected from one side in the gap region region (11a) to transfer to the other side in a non-adsorption manner. At this time, the gap region 11a in the present invention means a region forming a 'V' like shape in cross section between the roller 11 and the roller 11. At this time, the size of the gap between the roller 11 and the roller 11 so as not to fall out of the article to be inspected. For example, articles introduced into the gap region 11a of the non-adsorption roller conveying unit 10 may be delivered through the article input unit 15 described later or supplied to a separate article supply unit (not shown). .

Looking at the section according to the rotation of the non-adsorption roller transport unit 10, there is provided a transport section for transporting the article. The transport section of the non-adsorption roller transport unit 10 may include an article injection section 10a, a photographing section 10b, and a blowing section 10c. For example, the non-adsorption roller conveying unit 10 may be provided with an article input section 10a, in which case the article input section 10a is a section for receiving the items to be put and the conveyance of the non-adsorptive roller conveying unit 10. Start section of the section. That is, the transfer of articles in the article input section 10a is started. For example, the article input section 10a directly receives the article supplied from the article supply unit (not shown), or as shown in FIGS. 4 and 5, the article input section 10a installed at one end of the article input section 10a ( 15) it is possible to accept an article supplied from an article supply unit (not shown). For example, plates may be installed at both sides of the delivery progress direction of the article input section 10a to prevent the items from being delivered or put into the article input section 10a.

For example, the article input section 10a may be upwardly sloped or convexly curved upward. That is, the article injection section 10a may be inclined upward as shown in FIGS. 2, 3A and 3B, or may be curved upwardly convexly as shown in FIGS. 4 and 5. At this time, the alignment brush unit 20 may be installed at the distal end of the article injection section (10a). For example, referring to FIGS. 4 and 5, an article input unit 15 is installed at one end of the article input section 10a, and articles supplied from the article input section 15 are transferred to the article input section 10a. The articles may be placed and aligned in the gap region 11a by the alignment brush unit 20 installed at the distal end of the article injection section 10a according to the rotation of the non-adsorption roller transport unit 10.

In the non-adsorption roller conveying unit 10, the rollers 11 of the photographing section 10b of the conveying section rotate by themselves separately from the rotation of the non-adsorbing roller conveying unit 10. The photographing section 10b refers to a section in which photographing of the imaging unit 50 to be described later is performed among the transport sections. According to the rotation of the rollers 11 of the photographing section 10b, the imaging surface of the articles photographed by the imaging unit 50 is changed. For example, as the rollers 11 of the photographing section 10b self-rotate opposite to the rotational direction of the non-adsorption roller conveying unit 10 (refer to reference numeral Ra in FIG. 5), the gap region area between the rollers 11 ( The articles located in 11a) rotate and the imaging plane changes. At this time, at least the rotation of the rollers 11 of the photographing section 10b may be made by the roller rotation contributing unit 40 to be described later. Description of the roller rotation contributing unit 40 will be described later. For example, articles to be inspected for appearance may be formed to have a long length in the longitudinal direction, and may be easily positioned in parallel with the roller shaft in the gap region 11a between the rollers 11, where the vertical cross section with respect to the longitudinal direction of the articles may be It may be circular or near elliptical to similar shapes. Accordingly, the articles rotate easily according to the rotation of the rollers 11 of the photographing section 10b and the imaging surface can be changed. For example, in the case of a capsule-type drug such as a soft capsule or a hard capsule, the longitudinal length is long, and the vertical cross section with respect to the longitudinal direction is an elliptical structure having a circular shape or close to a circular shape, and thus the rotation of the rollers 11 of the photographing section 10b. As a result, the image capturing area can be changed by easy rotation.

For example, the photographing section 10b of the non-adsorbing roller conveying unit 10 may be formed at the highest point section of the rotation section of the non-adsorbing roller conveying unit 10. In addition, the blowing section 10c may be formed in an arc-shaped curved down curve section before the outermost point horizontally past the highest point section of the rotation section of the non-adsorption roller conveying unit 10.

For example, the plurality of rollers 11 constituting the non-adsorbing roller conveying unit 10 are rollers 11 having an axial length. The non-adsorption roller conveying unit 10 can arrange a plurality of articles in one gap region 11a by arranging rollers 11 having a long axial length in succession. For example, the articles to be inspected may have a long shape in one direction that is easy to be located in the gap region 11a between the rollers 11, where the long direction is in parallel with the roller shaft in the gap region 11a. Can be located. For example, at this time, the alignment brush unit 20 to be described later can be aligned so that the spacing between the articles in one gap region 11a is regular. Regular alignment by the alignment brush unit 20 will be described in detail below. For example, articles regularly aligned by the alignment brush unit 20 may be matched with positions of the plurality of air holes 71a provided in the air blower 71 of the discharge unit 70 to be described later.

For example, the non-adsorption roller conveying unit 10 may be formed by mounting the rollers 11 on the frame 12 or by connecting both ends of the rollers 11 with, for example, a pair of chains 13. 11) may be formed by fastening both ends of the chain connecting shaft, but is not limited thereto. 4 and 5 show a form in which the rollers 11 are mounted on the frame 12, and FIGS. 2, 3A and 3B show a form in which a pair of chains 13 are fastened to both ends of the rollers 11. It is shown. For example, referring to FIG. 4, when the rollers 11 are mounted on the frame 12, a portion of the roll body of the roller 11 to one end of the shaft 11 of the roller 11 may protrude from one side of the frame 12.

Imaging unit 50

Next, the imaging unit 50 will be described with reference to FIGS. 1, 2, 4 and / or 5. The imaging unit 50 includes a camera unit 51 and an illumination unit 53. The camera unit 51 is disposed on the outer upper portion of the non-adsorption roller transport unit 10. At this time, the camera unit 51 photographs the goods transferred through the non-adsorption roller transport unit 10. The lighting unit 53 is installed inside, outside or inside and outside of the non-adsorbing roller transfer unit 10. The lighting unit 53 illuminates the goods transferred through the non-adsorption roller conveying unit 10. In this case, the illumination installed inside the non-adsorption roller conveying unit 10 may be an infrared image of an article, such as a transparent or semi-transparent soft capsule drug, such as a light or a hard capsule drug, which is difficult to transmit light. It is to illuminate the lower side to be made, the illumination installed on the outside of the non-adsorption roller conveying unit 10 illuminates the image pickup surface of the articles.

The image pickup surface of the articles is rotated according to the rotation of the rollers 11 in at least the photographing section 10b (that is, at least the section in which the imaging unit 50 is photographed) among the article conveying sections of the non-adsorbing roller conveying unit 10. Is changed. The imaging surface of the articles means the surface to surface area photographed by the camera unit 51 disposed on the outer upper portion of the non-adsorption roller conveying unit 10. The camera unit 51 should have sufficient performance so as to capture the entire appearance of the articles according to the rotation of the articles according to the rotation of the rollers 11 of the photographing section 10b.

First, the camera unit 51 will be described. The camera unit 51 may be made of one camera 51a or a plurality of cameras according to the external inspection object. One article may be used when the articles are rotated at least one full turn in accordance with the rotation of the rollers 11 of the photographing section 10b and the areas at both ends of the article are inspected to one degree during one round, and the article may be used for one round. It is not enough to photograph both ends of the camera, so that the imaging surface for the both ends of the article is required separately, or the length of the gap region 11a where the articles are located is long, so that a single camera can obtain a sufficiently desired appearance image for a plurality of articles. If it is difficult to do so, a camera may be added. Alternatively, if there is a non-adsorbable article appearance inspection apparatus according to an example of the present invention, for example, different imaging methods such as transparent or semi-transparent soft capsule medicine and hard capsule medicine that are difficult to transmit light may be required. By taking a camera, different shots can be taken. 3A and 3B, the camera unit 51 of the imaging unit 50 is omitted, and only the lighting unit 53 is illustrated.

On the upper side of 10b), the photographing section 10b of the first camera 51a is illuminated. The second inner light 53b illuminates the photographing section 10b of the second camera 51b inside the non-adsorption roller conveying unit 10. In this case, the second camera 51b may be an infrared camera, and the second inner light 53b may be infrared illumination. In addition, the first inner light 53a and the outer light 53c may be LED lights. For example, not all of the lighting units 53 including the first inner light 53a, the outer light 53c, and the second inner light 53b shown in FIGS. 4 and 5 are not shown in FIGS. 2, 3A and 3B. It can also be implemented in the embodiments according to 2, 3a and 3b.

Meanwhile, although the photographed image photographed by the imaging unit 50 is not shown, the image may be processed by the image processing processor or the module and the image analysis may be performed by the read processor or the chip module. Image processing and image analysis of an image captured by the imaging unit 50 may be performed by an image analysis unit (not shown) including a processor, a chip module, and / or a software module. The discharge unit 70, which will be described later, is controlled according to the image reading result analyzed by the image analyzing unit (not shown), and the items to be transported are separated into defective and good products according to the control. Since the image processing processor and the module and the image reading processor and the module are already well known, a description thereof will be omitted.

Discharge Unit (70)

1 to 5, the discharge unit 70 will be described. Discharge unit 70 is installed on the other side of the non-adsorbing roller transfer unit (10). The discharge unit 70 separates and discharges the goods transferred through the non-adsorption roller conveying unit 10 into defective products and good products according to the reading result of the photographed image by the imaging unit 50.

For example, referring to FIGS. 2, 3A and / or 3B, in one example, the discharge unit 70 includes an air blower 71 and a reject outlet 73. 2 to 5, the air blower 71 is installed inside the other side of the non-adsorption roller conveying unit 10. In this case, referring to FIG. 3B, the air blower 71 includes a plurality of air holes 71a through which air is ejected. In FIG. 3B, some of the rollers 11 are omitted to show an air blower 71 having a plurality of air holes 71a. The air blower 71 corresponds to the position of the defective hole in the gap region 11a of the non-adsorption roller conveying unit 10 passing through the blowing section 10c according to the poor result of reading the photographed image. ) Emit air through each. Accordingly, the defective article located in the gap region 11a of the blowing section 10c may be discharged from the gap region 11a or blown out by the air through the defective article outlet 73. The blowing section 10c is a section in which air discharged through the plurality of air holes 71a of the air blower 71 is ejected to the gap region 11a of the non-adsorption roller conveying unit 10, that is, the air is ejected. It refers to a section in which the direction (see reference numeral Ba in FIG. 5) and the direction between the gap region 11a and the air hole 71a of the non-adsorption roller conveying unit 10 coincide.

For example, the blowing section 10c may be formed in an arc-shaped curved down curve section before the outermost point horizontally past the highest section where the photographing section 10b is formed among the rotation sections of the non-adsorption roller conveying unit 10. . In this case, the air blower 71 may inject air into a direction section between 1 and 2 o'clock of the downcurve section. For example, the blowing section 10c is formed in the direction section between 1 and 2 o'clock of the down curve section.

On the other hand, the defective product discharge port 73 is installed outside the other side of the non-adsorption roller transport unit (10). The defective product discharge port 73 discharges the defective products deviating from the gap region 11a of the non-adsorption roller conveying unit 10 by the discharge air of the air blower 71. For example, a defective article collector (not shown) may be provided below the defective article discharge port 73 to separately collect the defective article from the good article. In FIGS. 4 and 5, the defective discharge port 73 is not shown.

At this time, the good products which are read as a good result as a result of the reading of the photographed image and passed through the blowing section 10c are separated and discharged in the rear end region of the blowing section 10c. For example, the goods passed through the blowing section 10c are dropped in a vertical direction (see reference numeral Rb in FIG. 5) by their own weight as the non-adsorbing roller conveying unit 10 rotates (not shown). Can be collected separately. According to an embodiment, a separate article outlet (not shown) may be disposed in the rear end region of the blowing section 10c and the articles passing through the blowing section 10c may be separately collected by the article outlet through the article outlet.

Roller Rotation Contribution Unit (40)

Next, look at the non-adsorbable article appearance inspection apparatus according to another example of the present invention. At this time, the non-adsorbable article appearance inspection apparatus according to one example further includes a roller rotational contribution unit (40). For example, the roller rotation contributing unit 40 may be installed inside or outside of the non-adsorption roller conveying unit 10.

In one example, the roller rotation contributing unit 40 may cause at least the rollers 11 of the photographing section 10b to rotate opposite to the rotational direction Ra of the non-adsorption roller conveying unit 10. At this time, although the roller rotation contributing unit 40 is not shown, it may be installed at the lower portion of the photographing section 10b or inside the photographing section 10b inside the non-adsorption roller conveying unit 10, for example, The rollers 11 of the photographing section 10b may be installed to be fastened or abut against the rollers 11 of the photographing section 10b so as to rotate opposite to the rotation direction Ra of the non-adsorption roller conveying unit 10. have. Although the example in which the roller rotational contribution unit 40 is installed at the lower portion of the photographing section 10b is not directly illustrated, it is understood from the roller rotational contribution unit 40 installed at the lower portion of the article input section 10a in FIGS. 2, 3A and 3B. Can be. Or not shown, when the roller rotation contributing unit 40 is installed on the outside of the non-adsorption roller conveying unit 10 is installed on the outer upper portion and meshed with the outer peripheral surface of the rollers 11 or belt contact or installed on the outer side And the gear to the pulley formed on the end side protruding in the lateral direction of the rollers 11 can be engaged with the belt fastening. For example, although not directly shown, when the roller rotation contributing unit 40 installed at the lower side or the outer side of the photographing section 10b includes the pulley belt and the pulley, the pulley belt abuts against the outer circumferential surfaces of the rollers 11 or the roller shaft. An example of abutting the pulley formed at the protruding end is that the roller rotation contributing unit 40 shown in FIGS. 2, 3A and 3B has a pulley belt 41 and a pulley 42 and the pulley belt 41 has rollers 41. It can be understood from the structure that abuts the lower outer peripheral surface of the).

For example, the roller rotation contributing unit 40 may rotate not only the rollers 11 of the photographing section 10b but also the rollers 11 of the article feeding section 10a among the remaining transport sections other than the photographing section 10b. . For example, referring to FIGS. 2, 3A and / or 3B, the roller rotation contributing unit 40 installed below the article input section 10a of the conveying section may include the rollers 11 of the article input section 10a. It can be rotated opposite to the rotation direction (Ra) of the non-adsorption roller conveying unit 10. That is, the roller rotation contributing unit 40 may be installed at the lower side or the upper side of the point within the transport section horizontally spaced apart from the upper and lower side of the photographing section 10b. For example, the roller rotation contributing unit 40 directly rotates the rollers 11 of the article input section 10a so that the rollers 11 rotated according to the rotation of the non-adsorption roller conveying unit 10 are photographed. It may also continue to rotate while passing through section 10b. That is, for example, the rollers of the photographing section 10b also by the roller rotation contributing unit 40 installed in the lower portion of the article input section 10a rather than the lower side or the upper side of the photographing section 10b in FIGS. 2, 3a and / or 3b. 11 may be rotated in the opposite direction to the rotation direction of the non-adsorption roller conveying unit 10. For example, although not shown, the roller contacting the rollers 11 of the shooting section 10b on the lower side or the upper side of the shooting section 10b separately from the roller rotation contributing unit 40 shown in FIGS. 2, 3a and / or 3b. Rotational contribution unit 40 may be installed. For example, in FIG. 2, 3a and / or 3b, the roller rotation contributing unit 40 installed at the lower part of the article input section 10a is provided with a rotating belt driven by power so as to contact the outer circumferential surfaces of the rollers 11 so as to contact the rollers. The field 11 may be rotated in the opposite direction to the rotation direction of the non-adsorption roller transport unit 10.

In one example, although not shown, the roller rotation contributing unit 40 may have at least a rotational belt contacting the outer circumferential surface of the rollers 11 of the photographing section 10b to the outer circumferential surface, or a non-rotating contact surface. For example, when the roller rotation contributing unit 40 has a non-rotating contact surface which is in contact with the rollers 11 of the photographing section 10b, the roller rotation contributing unit 10 may not absorb the rollers 11 of the photographing section 10b. In order to rotate in the opposite direction of rotation), it may be installed on the outside of the non-adsorbing roller transfer unit 10. For example, the rotating belt which abuts the outer circumferential surface of the rollers 11 of the photographing section 10b to the outside is rotated in the same direction as the rotational direction Ra of the non-adsorption roller conveying unit 10 according to the power driving and photographing section 10b. The rollers 11 of) may be reversed. Alternatively, the rotating belt which abuts the outer circumferential surface of the rollers 11 to the outside may be driven with the reverse rotation of the rollers 11 of the photographing section 10b according to the frictional force with the outer circumferential surfaces of the rollers 11 of the photographing section 10b. Can rotate When the roller rotation contributing unit 40 is provided with a rotating belt, the rotating belt is provided on the outside of the non-adsorption roller conveying unit 10 for reverse rotation of the rollers 11 of the photographing section 10b together with the non-powered rotation. It may be installed and may be installed inside or outside the non-adsorption roller conveying unit 10 when the power is driven. For example, the rotating belt which abuts the outer peripheral surface of the rollers 11 of the photographing section 10b to the outside is not directly shown, but the pulley belt 41 of the roller rotation contributing unit 40 shown in FIGS. 2, 3A and 3B is It can be understood from abutting the lower outer circumferential surfaces of the rollers 11 of the article injection section 10a.

Although not shown, in another example, a gear or pulley structure may be provided at one side of the plurality of rollers 11. At this time, the roller rotational contribution unit 40 installed on the inner side or the outer side of the non-adsorption roller conveying unit 10 is at least a chain that is fastened or abuts with the gear or pulley structure of the rollers 11 of the photographing section 10b, Timing belt or pulley belt may be provided. The chain, the timing belt, or the belt for the pulley may rotate in the same direction as the rotation direction Ra of the non-adsorption roller transport unit 10 according to the power drive and may reversely rotate the rollers 11 of the photographing section 10b. . Alternatively, the chain, the timing belt, or the pulley belt may rotate in a non-motorized manner with the reverse rotation of the rollers 11 of the photographing section 10b according to the reaction force or frictional force with the rollers 11 of the photographing section 10b. . For example, reaction forces can be applied in the case of chains or timing belts, and friction forces can be applied in the case of pulley belts.

Alignment Brush Unit (20)

Next, look at the non-adsorbable article appearance inspection apparatus according to another example of the present invention. 1 to 5, the non-adsorbable article appearance inspection apparatus according to an example may further include an alignment brush unit 20. The alignment brush unit 20 is installed at one side of the non-adsorption roller transport unit 10. For example, the alignment brush unit 20 may be installed at the distal end of the article injection section 10a of the non-adsorption roller transport unit 10. The alignment brush unit 20 aligns the articles accommodated in the article input section 10a with the gap region 11a of the non-adsorption roller conveying unit 10 as the non-adsorption roller conveying unit 10 rotates. Articles aligned by the alignment brush unit 20 may be aligned in the gap region 11a of the non-adsorption roller transport unit 10 with the length in the longitudinal direction parallel to the roller shaft.

For example, the alignment brush unit 20 may align at regular intervals between articles in one gap region 11a. Regular intervals may basically be intervals that are all substantially the same, and the intervals are called basic intervals. Regular intervals include not only basic intervals but also enlarged enlargement intervals in the case of missing goods scheduled between the basic intervals. That is, not only when the articles are all aligned at substantially the same basic interval in one gap region 11a but also when some of the articles scheduled to be aligned with respect to the basic interval are missing, the enlarged result of missing scheduled items between the basic intervals is increased. The case of the alignment including the magnification interval is called regular interval. At this time, the basic spacing between the articles arranged at regular intervals by the alignment brush unit 20 can be matched with the intervals of the plurality of air holes (71a) provided in the air blower 71 of the discharge unit (70). have. That is, when the articles are all aligned at substantially the same basic spacing in one gap region 11a by the alignment brush unit 20, the position of the articles is a plurality of air blowers 71 passing through the blowing section 10c. It may correspond to the position of the air hole (71a) of.

For example, the alignment brush unit 20 may be an alignment brush. At this time, the alignment brush is rotated in the same direction as the rotation direction (Ra) of the non-adsorptive roller transfer unit 10 may be aligned with the gap region (11a) of the non-adsorption roller transfer unit 10. For example, the alignment brush may be alternately formed with grooves and protrusions at regular intervals along the longitudinal direction around the periphery so that the articles can be aligned in the substantially predetermined basic interval unit in each gap region region 11a. For example, the protrusion of the alignment brush may be swept to the inner side of the gap region 11a between the roller 11 and the roller 11 as it rotates, and may be arranged at basic intervals between the articles. In addition, for example, the groove portion of the alignment brush may serve to sweep out the excess article when one article placed in the gap region 11a between the roller 11 and the roller 11 exceeds. . For example, the excess article among the articles stacked in multiple layers in the gap region 11a of the article input section 10a to the article input section of the non-adsorbing roller conveying unit 10 is wiped out by the groove portion of the alignment brush. And the articles may be arranged in a single layer instead of multiple layers in the gap region region 11a, falling backward according to the reverse rotation and the inclination to the curved structure of the roller. That is, the article input section 10a to the article input section of the non-adsorbing roller conveying unit 10 form an upwardly inclined to convex curve in the conveying direction, and the rollers 11 in the section are themselves non-adsorbing roller conveying units ( Since the reverse direction is reversed to the rotation direction of 10), the excess article accumulated on one article in the gap region 11a can interact with the sweep by the groove portion of the alignment brush or without the friction by the groove portion of the alignment brush. By this, it can be rolled backward and arranged in a single layer.
