Detailed ways

Hereinafter, the Example of this invention is demonstrated using drawing.

FIG. 1 is a schematic configuration diagram of an inspection device S according to the present embodiment viewed from above. In FIG. 1 , the inspection device S inspects the appearance and content of the object PS mounted on the outer periphery of the inspection star wheel 2 by using the inspection unit 4 having a camera for inspection, etc. The sorting unit 6 sends out a good product, or the sorting star wheel 7 discharges a defective sample PS to a discharge unit (discharge tray) 8 .

Here, the object PS to be inspected by the inspection device S of this embodiment is, for example, a translucent container filled with a translucent liquid such as an ampoule, vial, or prefilled syringe.

On the other hand, for a large number of samples PS supplied in an upright state to the supply conveyor 9 that is gradually inclined downward toward the supply direction of the samples PS, the conveyance width is limited to a relatively small amount in the supply direction. The narrow guide member 10 guides and supplies to the supply star wheel 13 via the supply guide member 11 . Reference numeral 12 denotes a guide member driving unit of the supply guide member 11 . Next, the subject PS is supplied to the inspection starwheel 2 via the transfer starwheel 14 and is loaded on the inspection starwheel 2 .

Defective samples PS among the samples PS are discharged from the sorting star wheel 7 , conveyed through the path 51 , and discharged to the discharge unit 8 .

Next, the connection part a between the sorting star wheel 7 and the passage 51 is demonstrated.

6(a) to 6(d) illustrate the passage of the subject PS from the sorting star wheel 7 to the passage 51 in the connection part a in the order of FIGS. 6(a) to 6(d) over time. A diagram of the subject of the handover situation. As described above, the picking star wheel 7 is driven to rotate in the direction of the arrow 55 to convey the subject PS. Then, the sorting star wheel 7 delivers the object PS to the passage 51 .

In the passage 51, the direction of the arrow 56 is defined as the downstream side, and the objects PS sorted out by the star wheels as defective products are carried out from the sorting star wheels 7 and arranged, and are carried out from the sorting star wheels 7. The subsequent subjects PS move in the sequence shown in Fig. 6(a) and Fig. 6(b). Thereby, as shown in the order of FIG. 6( c ) and FIG. 6( d ), the subjects PS arranged in the path 51 are pressed by the subjects PS carried out from the sorting star wheel 7 . Therefore, in the path 51 , the preceding subject PS is pushed by the following subject PS, moves from the upstream side to the downstream side in the direction of the arrow 56 , and is carried out toward the discharge unit 8 ( FIG. 6( d )). In this way, no power for transporting the subject PS is provided in the path 51 , and each subject PS is pressed by the subsequent subject PS carried out from the sorting star wheel 7 side to move sequentially in the direction of the arrow 56 .

As a result, the subjects PS arranged in the path 51 are at rest when the subjects PS are not supplied from the sorting starwheel 7, and the subsequent subjects PS carried out from the sorting starwheel 7 are aligned with the sorting starwheel 7. The predetermined speed corresponding to the rotational speed of the wheel 7 comes into contact with the last subject PS on the path 51 ( FIG. 6( c )).

Therefore, when the subsequent sample PS from the side of the sorting star wheel 7 comes into contact with the last sample PS on the path 51 , there is a possibility that the sample PS may be damaged.

In contrast, the above-mentioned non-patent document 1 discloses the following technology: using the synchronous screw to transport the container after coming out of the automatic machine on the guide rail, by gradually reducing the pitch of the synchronous screw, so as to approach the last container arranged on the guide rail The speed of handling containers can be reduced without breaking the containers.

However, the device of Non-Patent Document 1 has a large device structure, which has the problem of increasing the manufacturing cost and increasing the size of the device.

Therefore, in the inspection apparatus S of the present embodiment, the buffer device 60 shown in FIG. 2 is provided to prevent the occurrence of the above-mentioned problems. Hereinafter, a detailed structure of the buffer device 60 will be described. FIG. 2( a ) is a plan view of the shock absorber 60 , and FIG. 2( b ) is a front view of the shock absorber 60 .

The buffer device 60 is disposed in the vicinity of the passage 51 so as to face the side of the sorting star wheel 7 across the passage 51 in a region where the object PS is passed from the sorting star wheel 7 to the passage 51 . The buffer device 60 includes a buffer member 61 . The buffer member 61 is sandwiched between the two samples PS when the sample PS discharged from the sorting star wheel 7 comes into contact with the preceding sample PS on the path 51, and buffers the two samples PS. parts in contact.

On both sides of the passage 51 , side guides 58 , 59 as guide members for forming the passage 51 are provided. Further, the buffer member 61 is rotatably attached to the side guide 58 via a rotation shaft 62 .

The cushioning member 61 is an impeller-shaped member, and has a plurality of receiving portions 63 formed continuously in the circumferential direction and receiving the subject PS, and between the receiving portions 63 protruding in the radial direction of the buffering member 61, the cushioning is provided. The buffer portion 64 for the contact between the specimens PS. The cushioning member 61 is pressed by the subject PS received by the receiving portion 63 , and rotates in its circumferential direction with the rotation shaft 62 as a rotation center.

FIG. 3 is a plan view of the cushioning member 61 . Various materials can be used as the forming material of the cushioning member 61 , especially the cushioning portion 64 thereof, but rubber is preferable because it can improve elasticity.

FIG. 4 is a plan view of another example of the cushioning member 61 . That is, as shown in the example of FIG. 4 , a notch 65 may be formed in the longitudinal center portion of the buffer portion 64 to increase the elasticity of the buffer portion 64 .

Returning to FIG. 2 , the shock absorber 60 includes a ratchet mechanism 70 . The ratchet mechanism 70 includes a support base 71 fixed to the side guide 58 , a leaf spring 72 whose one end is fixed to the support base 71 , and a roller frame 73 fixed to the other end of the leaf spring 72 . A roller 75 is provided at a front end portion of the roller frame 73 so as to be rotatable in the horizontal direction via a rotating shaft 74 .

On the upper portion of the buffer member 61 of the rotating shaft 62, a contact portion (cam plate) 76 is provided. In the peripheral portion of the contact portion 76, a plurality of concave portions 77 having a concave shape corresponding to the peripheral surface of the roller 75 are continuously formed. The roller 75 elastically abuts against the abutting portion 76 by the elastic force of the leaf spring 72 .

In this way, the roller 75 of the ratchet mechanism 70 comes into contact with the contact portion 76 , and the rotational position of the buffer member 61 provided coaxially is positioned by the contact portion 76 and the rotation shaft 62 . Then, the rotational position of the buffer member 61 is positioned so as to be arranged at a position where, after the buffer member 61 is rotated by the ratchet mechanism 70 and the buffer unit 64 buffers the preceding subject PS, The position where the subsequent subject PS is blocked by the subsequent buffer unit 64 can be buffered (the detailed configuration will be described later).

That is, when the buffer portion 64 is not pushed by the object PS carried out from the picking star wheel 7, the roller 75 is engaged with one concave portion 77 of the abutting portion 76 due to the elastic force of the plate spring 72, thereby determining the buffer member. 61 stop position. Then, the buffer portion 64 protruding toward the passage 51 side is located in the passage 51 , and is pressed by the subject PS carried out from the sorting star wheel 7 . Accordingly, the buffer member 61 rotates against the elastic force of the leaf spring 72 , and the roller 75 engages with the next concave portion 77 of the contact portion 76 , thereby determining the next stop position of the buffer member 61 .

Next, the detailed operation of the buffer member 61 by the ratchet mechanism 70 will be described. 5( a ) to 5( f ) are explanatory diagrams illustrating the operation of the cushioning member 61 in the order of FIGS. 5( a ) to 5( f ) over time. In FIGS. 5( a ) to 5 ( f ), arrow 81 indicates the rotation direction of sorting star wheel 7 , and arrow 82 indicates the rotation direction of buffer member 61 .

First, when the buffer portion 64 is not pushed by the object PS carried out from the sorting star wheel 7, as shown in FIG. The subjects PS and the subjects PS unloaded from the sorting star wheel 7 exist at a distance from these subjects PS.

Next, as shown in FIG. 5( b ), when the object PS is carried out from the sorting star wheel 7, the object PS enters the receiving portion 63, and the above-mentioned buffer portion 64 is pushed by the object PS, And the buffer member 61 starts to rotate. As a result, the distance between the last object PS in the path 51 and the object PS on the side of the sorting star wheel 7 is reduced.

Next, as shown in FIG. 5( c ), since the object PS on the side of the sorting star wheel 7 further presses the aforementioned buffer portion 64 due to the rotation of the sorting star wheel 7 , the buffer member 61 further rotates. As a result, the buffer member 61 presses the last subject PS in the passage 51 , and the subjects PS arranged in the passage 51 move in the direction of the arrow 83 .

Next, as shown in FIG. 5( d ), since the object PS on the side of the sorting star wheel 7 further pushes the above-mentioned buffer portion 64 due to the rotation of the picking star wheel 7 , the buffer member 61 and FIG. 5 ( c) is rotated further than the state. As a result, the buffer member 61 presses the last subject PS in the passage 51 , and the subjects PS arranged in the passage 51 move further in the direction of the arrow 83 than in the state of FIG. 5( c ). Then, the rotation of the buffer member 61 advances compared to the state shown in FIG. 64 starts to leave between the two subjects PS. As a result, the distance between the two subjects PS is reduced.

Next, as shown in FIG. 5( e ), since the object PS on the side of the sorting star wheel 7 further presses the above-mentioned buffer portion 64 due to the rotation of the picking star wheel 7 , the buffer member 61 and FIG. 5 ( d) is rotated further than the state. Then, the buffer member 61 presses the last subject PS in the passage 51 , and the subjects PS arranged in the passage 51 move further in the direction of the arrow 83 than in the state of FIG. 5( d ). Then, the rotation of the buffer member 61 advances compared to the state of FIG. 64 is farther away from between the two subjects PS than in the state of FIG. 5( d ). As a result, the distance between the two subjects PS is further reduced compared to the state shown in FIG. 5( d ).

Next, as shown in FIG. 5(f), since the object PS on the side of the sorting star wheel 7 further presses the above-mentioned buffer portion 64 due to the rotation of the picking star wheel 7, the buffer member 61 and FIG. The state of e) is further rotated than that. At this time, the object PS on the side of the sorting star wheel 7 is almost separated from the sorting star wheel 7 . Then, the buffer portion 64 sandwiched between the sample PS on the side of the sorting star wheel 7 and the last sample PS of the passage 51 is almost completely separated from between the two samples PS. As a result, the object PS on the side of the star wheel 7 is in contact with the object PS at the end of the path 51, but since the buffer portion 64 exists between the two objects PS, the object PS on the side of the star wheel 7 is picked up. The object PS at the end of the path 51 contacts the object PS at the end of the path 51 in a state sufficiently decelerated compared with the conveyance speed of the sorting star wheel 7 .

As described above, the cushioning member 61 is an impeller-shaped member, and includes a plurality of receiving portions 63 formed continuously in the circumferential direction to receive the subject PS, and between the receiving portions 63 , the cushioning member 61 protrudes in the radial direction of the buffering member 61 . A buffer unit 64 is provided to buffer the contact between the subjects PS. In addition, the intervals between the respective receiving portions 63 and the respective buffer portions 64 are as shown by way of example in FIG. 3 (or FIG. 4 ). As a result, the buffer member 61 is arranged in a shape that does not interfere with the preceding subject PS (the last subject PS in the path 51 ) after the buffer member 61 rotates and the buffer unit 64 buffers the preceding subject PS. The position of the subsequent sample PS on the star wheel 7 side can be buffered by the next buffer unit 64 . The state in which the buffer unit 64 is arranged at a position where the subsequent subject PS can be buffered by the next buffer unit 64 without interfering with the subsequent subject PS on the side of the star wheel 7 in this case is the above-mentioned FIG. 5 . (a) State.

In addition, when the buffer member 61 is in contact with the object PS at the end of the path 51 and the object PS on the side of the sorting star wheel 7 , it is possible to reduce the utilization of the subsequent object PS on the side of the picking star wheel 7 . The speed of movement of the star wheel 7 is set to a minimum.

5(a) to 5(f), a method for carrying out the container is realized: using the buffer member 61 provided at the entrance of the passage 51, the object PS discharged from the sorting star wheel 7 is When coming into contact with the preceding subject PS on the path 51 , it is sandwiched between the two subjects PS to cushion the contact with the two subjects PS.

According to the inspection apparatus S described above, the buffer portion 64 of the buffer member 61 is interposed between the last object PS of the path 51 and the object PS on the side of the sorting star wheel 7, and both objects PS are buffered. s contact. Thus, it is possible to provide a device that realizes low manufacturing cost and miniaturization of the device, and does not damage the object PS at the end of the path 51 due to contact with the object PS on the side of the sorting star wheel 7 . Check the device S and the method of carrying out the container.

Further, the buffer member 61 includes a plurality of receiving portions 63 formed continuously in the circumferential direction to receive the subject PS, and a buffer portion protruding radially between the receiving portions 63 to buffer the contact between the two subjects PS. 64, and the rotating shaft 62 for rotating the buffer member 61 pressed by the subject PS in the circumferential direction. Thus, using the cushioning device 60 centered on the cushioning member 61 having a relatively simple structure, it is possible to achieve low manufacturing costs, downsizing the device, and preventing damage to the subject PS.

In addition, when the buffer member 61 shown in FIGS. 3 and 4 is made of rubber, it can elastically hold the subject PS, which is preferable in terms of preventing damage to the subject PS.

In addition, as shown in FIG. 4 , if the notches 65 in the longitudinal direction are formed in the cushioning portion 64 , the elasticity of the cushioning portion 64 can be improved, which is of course preferable in preventing damage to the subject PS.

In addition, as described above, the buffer member 61 is disposed so that after the preceding subject PS is buffered by the buffer unit 64 after the buffer member 61 rotates, the subsequent subject PS can be buffered by the next buffer unit 64 without interfering with the subsequent subject PS. This subsequent shape of the position of the subject PS ( FIG. 5( a ), FIG. 3 , FIG. 4 ). Accordingly, the buffer unit 64 does not hinder the entry of the subject PS from the side of the sorting star wheel 7 , and damage to the subject PS can be prevented.

In addition, the buffer member 61 minimizes the subsequent movement speed of the subject PS on the side of the sorting star wheel 7 caused by the driving of the sorting star wheel 7 when it comes into contact with the above-mentioned two subjects PS. Accordingly, the moving speed of the subject PS carried out from the side of the sorting star wheel 7 to the passage 51 can be sufficiently reduced, and damage to the subject PS can be prevented.

In addition, since the ratchet mechanism 70 and the abutting portion 76 abutting against the roller 75 of the ratchet mechanism 70 are provided, the rotational position of the buffer member 61 can be appropriately positioned by placing it on the buffer member 61. After the previous subject PS is buffered by the buffer unit 64 by rotation, the subsequent subject PS can be buffered by the next buffer unit 64 without interfering with the subsequent subject PS.

In addition, this invention is not limited to the said Example, Various modified examples are included. For example, the above-mentioned embodiment is the embodiment which demonstrated in detail in order to understand this invention easily, and is not limited to what must have all the structures demonstrated.
