1. The overall structure of the container inspection device The overall structure of the container inspection device 1 will be described with reference to Figs. 1 to 3. Figure 1 is a plan view of the container inspection device 1 of this embodiment, Figure 2 is a front view of the first discharge portion 30 of the container inspection device 1 of this embodiment, and Figure 3 is a view of the container inspection device 1 of this embodiment Partial enlarged view of the top view. In FIG. 3, in order to explain the first pushing mechanism 60 and the second pushing mechanism 62, the first star wheel 10 is omitted.

As shown in Figures 1 to 3, the container inspection device 1 is provided with: a first star wheel 10 provided with a accommodating portion 16 of a plurality of accommodating containers 3 on the periphery 14, and an inspection portion arranged at a position where the accommodating portion 16 stops 20. The first discharge portion 30 and the second discharge portion 32. Although the second discharge part 32 is adjacent to the first discharge part 30, other stop positions may be interposed therebetween. The container inspection device 1 is provided with a first conveyor 40 arranged facing the first discharge unit 30 and a second conveyor 42 arranged facing the second discharge unit 32. When the second conveyor 42 is provided with a mechanism that does not require the container 3 to stand on its own, such as a blowing machine, the second discharge portion 32 may not be provided with the second holding mechanism 52.

And as shown in Fig. 3, the container inspection device 1 is under the first star wheel 10 and has the same center of rotation 5 as the first star wheel 10, and is arranged vertically and spaced apart from the first star wheel 10 The second star wheel 12. Since the container 3 can be held up and down by using two star wheels, it can be carried stably.

The first discharge unit 30 discharges the container 3 determined to be a good product by the inspection by the inspection unit 20 toward the first conveyor 40, and the second discharge unit 32 discharges the container 3 determined to be a defective product by the inspection by the inspection unit 20 toward the first conveyor 40. The second conveyor 42 discharges. According to the container inspection device 1, the self-standing stability of the container 3 of good product and the container 3 of defective product can be improved separately. The container 3 discharged from the first discharge part 30 is self-standing on the first conveyor 40 outside the peripheral edge 14. The container 3 discharged from the second discharge portion 32 is self-standing on the second conveyor 42 outside the peripheral edge 14.

The container 3 is, for example, a glass bottle. The container 3 may be an inverted cone-shaped bottle with a smaller diameter from the head of the first conveyor 40 and the second conveyor 42 with relatively poor self-standing stability toward the bottom, and a larger diameter from the head to the bottom. A bottle with a cone-shaped bottle and a higher center of gravity of the container 3. In particular, glass bottles are often heavier than containers 3 made of other materials. Because of the design of the container 3, the weight balance between up and down is likely to deviate. Therefore, it is desirable to use the first holding mechanism 50 and the second holding mechanism. The mechanism 52 improves self-support stability.

The container inspection device 1 includes a control device 7. The control device 7 is a device that performs various calculations and controls. The structure of the device can include: CPU, memory (RAM, ROM) and external memory device for calculation and control, and further includes a monitor, keyboard, mouse and interface . The functional components of the control device 7 include at least a control unit 70, a storage unit 72, and a calculation unit 74. The calculation unit 74 uses programs, data, etc., retrieved from the storage unit 72, and data retrieved from the inspection unit 20, to perform predetermined calculations. The calculation unit 74 determines whether all the containers 3 supplied to the container inspection device 1 are good or defective based on the calculation result. The control unit 70 outputs an instruction to discharge the container 3 determined as a good product from the first discharge unit 30 to the first conveyor 40, and outputs the container 3 determined as a defective product from the second discharge unit 32 to the second Conveyor 42 discharge instructions.

In addition, the container inspection device 1 includes a first holding mechanism 50 that holds the container 3 in the accommodating portion 16 in the first discharge portion 30, and a second holding mechanism 50 that holds the container 3 in the accommodating portion 16 in the second discharge portion 32. The holding mechanism 52, the first pushing mechanism 60 that pushes the container 3 out from the first discharge portion 30 in the discharge direction, that is, the first direction D1, and the second discharge portion 32, pushes the container 3 in the discharge direction, that is, the second direction D2 Launched the second launch mechanism 62.

The container inspection device 1 includes a machine 2. The machine 2 rotatably supports the first star wheel 10 and the second star wheel 12, and supports the first holding mechanism 50, the second holding mechanism 52, the first pushing mechanism 60, and the second pushing mechanism 62 on Specify the location. Since the first holding mechanism 50, the second holding mechanism 52, the first pushing mechanism 60, and the second pushing mechanism 62 are supported at predetermined positions of the machine table 2, even if the container inspection device 1 is increased in speed, the same mechanism can be suppressed. The container 3 is discharged stably by shaking. The machine 2 can also be separated: the part supporting the first star wheel 10 and the second star wheel 12, the part supporting the first holding mechanism 50 and the first pushing mechanism 60, and the second holding mechanism 52 and the second 2 The part supported by the push-out mechanism 62 may also integrate these connections.

The first star wheel 10 and the second star wheel 12 intermittently rotate in a horizontal plane to transport the container 3 housed in the storage unit 16 from the inspection unit 20 to the first discharge unit 30. The rotation center 5 of the first star wheel 10 and the second star wheel 12 extends from the machine table 2 in the vertical direction. In the present embodiment, there are eight accommodating parts 16 on the peripheral edge 14, and the container 3 is held in each of the accommodating parts 16 and conveyed to the stop position of eight places. The number of accommodating parts 16 and the number of stopping positions are not limited to eight, and can be appropriately set according to the processing capacity of the container inspection device 1. Since the second discharge part 32 discharges the container 3 that has not been discharged onto the first conveyor 40 in the first discharge part 30, it is in the storage part 16 of the second discharge part 32 in FIGS. 1 and 3. Container 3 is not contained. The accommodating portion 16 is a notch that is curved from the peripheral edges 14 of the first star wheel 10 and the second star wheel 12 of the disc shape toward the rotation center 5. Each accommodating portion 16 of the first star wheel 10 is provided with a pair of support rings 17 that suppress the floating of the container 3 while supporting the rotation of the head of the container 3.

In the stop position of the accommodating part 16, there are provided: a supply part 18 that supplies the container 3 to the container inspection device 1, and a first inspection part 22, a second inspection part 24, and a third inspection part 26 that inspect the container 3 The inspection part 20, the first discharge part 30, and the second discharge part 32 of the same. The supply unit 18 may be provided with a propulsion conveyor that sequentially sends the containers 3 to the storage unit 16 stopped at the supply unit 18. The container 3 stopped at each stop position of the inspection unit 20 performs various inspections while rotating around the center axis of the container 3.

The first conveyor 40 conveys the container 3 pushed out from the accommodating portion 16 by the first pushing mechanism 60 in the first direction D1 away from the first discharge portion 30 in a self-standing state in the first discharge portion 30. The first direction D1 is the discharge direction of the container 3. The second conveyor 42 conveys the container 3 pushed out by the second ejection mechanism 62 from the accommodating portion 16 in a self-standing state in the second direction D2 away from the second discharge portion 32 in the second discharge portion 32. The second direction D2 is the discharge direction of the container 3. The first conveyor 40 and the second conveyor 42 may be belt conveyors that drive endless (loop)-shaped belts intermittently or continuously. In this embodiment, they are driven continuously. The first conveyor 40 and the second conveyor 42 convey the container 3 in a self-standing state on the upper surface. The first conveyor 40 extends from directly below the accommodating portion 16 in the first discharge portion 30 to the outside of the peripheral edge 14, and the second conveyor 42 extends from directly below the accommodating portion 16 in the second discharge portion 32 to the peripheral edge Extend to 14 outside.

The container 3 is arranged on the first conveyor 40 by being conveyed to the first discharge part 30, and the container 3 is arranged on the second conveyor 42 by being conveyed to the second discharge part 32. In this embodiment, the first conveyor 40 extends to stop under the container 3 of the first discharge part 30, but the container 3 is pushed out by arranging the first conveyor 40 to face the first discharge part 30. What is necessary is to transmit in a self-standing state, and for example, the first conveyor 40 may extend from the outer side of the peripheral edge 14 in the first direction D1. Similarly, the second conveyor 42 may extend in the second direction D2 from the outer side of the peripheral edge 14, for example.

The first conveyor 40 and the second conveyor 42 move the container 3 in a self-supporting state, so when the container 3 is pushed by the first pushing mechanism 60 and the second pushing mechanism 62, it will shake and lack self-support. stability. If the container 3 falls on the first conveyor 40 or the second conveyor 42, the container inspection device 1 needs to be stopped urgently, so the processing capacity per unit time of the container inspection device 1 will be significantly reduced. Therefore, stabilization of the movement of the container 3 from the first discharge portion 30 (second discharge portion 32) to the first conveyor 40 (second conveyor 42) is important.

2. Keep the organization The holding mechanism will be explained using Figs. 2 and 3. In the container inspection apparatus 1 of the present embodiment, the holding mechanism includes the first holding mechanism 50 and the second holding mechanism 52, but the basic structure is the same for both mechanisms, so the first holding mechanism 50 will be mainly described.

As shown in Figure 2, the first holding mechanism 50 is provided with: at least the side surface of the container 3 that is transported toward the first discharge portion 30 can be contacted by the rotation of the first star wheel 10 and the second star wheel 12 One arm and an electric motor 57 that rotates the arm to switch the first holding mechanism 50 to the closed state and the open state. In the "closed state", the arm is brought into contact with the side surface of the container 3, and the movement of the container 3 in the first direction D1 is restricted by the arm. In the open state, the arm is rotated to release the contact with the side surface of the container 3. In the first holding mechanism 50 of the present embodiment, an example in which a total of four arms are provided in the vertical and horizontal directions will be described.

As shown in Figure 2, the first holding mechanism 50 is provided with two rotating shafts that are erected across the first conveyor 40 at a first interval W1 wider than the full width W of the container 3, that is, the first The rotating shaft 53 and the second rotating shaft 54 and the first and second rotating shafts 53 and 54 each have two arms arranged vertically with a second interval W2, that is, the first arm 55 and the second arm 56 , And an electric motor 57 that rotationally drives the first rotating shaft 53 and the second rotating shaft 54. The opening and closing of the first arm 55 and the second arm 56 can be accelerated by the electric motor 57. Since the first arm 55 and the second arm 56 which are arranged up and down can hold the upper and lower sides of the side of the container 3, even if the shape of the container is easy to shake, it should move from the first star wheel 10 and the second star wheel 12 to the The self-standing stability of the container 3 can also be improved when the conveyor 40 moves on. In the present embodiment, two arms are arranged up and down, but it is not limited to this, and one arm may be arranged on each rotating shaft. In addition, by opening and closing the first arm 55 and the second arm 56 fixed to each of the first rotating shaft 53 and the second rotating shaft 54 like a double door, it is possible to quickly move from the first discharge part 30 to the first The container 3 being conveyed on the conveyor 40. As a result, according to the container inspection device 1 described above, the stop time of the star in the first discharge unit 30 can be shortened. Furthermore, since the first arm 55 and the second arm 56 are opened in the first direction D1, the movement of the container 3 is not hindered, and the self-standing stability of the container 3 during high-speed discharge can be improved even if the container shape is easily shaken.

The first direction D1 is the direction in which the container 3 is pushed out from the accommodating portion 16 by the first pushing mechanism 60 and is the same as the conveying direction of the first conveyor 40. The first rotating shaft 53 and the second rotating shaft 54 are erected across the first conveyor 40. The lower ends of the first rotating shaft 53 and the second rotating shaft 54 are respectively connected to the electric motor 57, and the upper ends thereof extend vertically upward and are rotatably supported near the height of the head of the container 3.

Although the electric motor 57 is provided in each of the first rotating shaft 53 and the second rotating shaft 54, the output of one electric motor 57 may be divided into the rotation of the first rotating shaft 53 and the second rotating shaft 54. The electric motor 57 may reciprocate the first rotation shaft 53 and the second rotation shaft 54 around the shaft at an angle of 90 degrees. The electric motor 57 may be a servo motor. By using a servo motor, the first rotating shaft 53 and the second rotating shaft 54 can be rotated at a high speed.

The electric motor 57 rotates the first rotating shaft 53 and the second rotating shaft 54 to switch the first arm 55 and the second arm 56 to the closed state and the open state. In the closed state, the contact portion 554 of each of the first arm 55 and the second arm 56 is brought into contact with the side surface of the container 3 in the first discharge portion 30 to restrict the movement of the container 3 in the first direction D1. In the open state, the first arm 55 and the second arm 56 are rotated toward the first conveyor 40 to allow the container 3 to move from the first discharge portion 30 in the first direction D1. The first arm 55 and the second arm 56 revolve around the first rotation shaft 53 and the second rotation shaft 54 to open and close like a double door when viewed from the front in FIG. 2.

The first arm 55 and the second arm 56 have: a fixed end 550 fixed to the first rotating shaft 53 or the second rotating shaft 54, and a free end 552 opposite to the fixed end 550, and a free end 552 is adjacent to the contact portion 554 shown in FIG. 3. The free ends 552 of the first arm 55 and the second arm 56 fixed to the first rotation shaft 53 on one side, and the free ends of the first arm 55 and the second arm 56 fixed to the second rotation shaft 54 on the other side 552 extends from the first rotating shaft 53 and the second rotating shaft 54 (fixed end 550) which are respectively fixed in the closed state so as to be close to each other. The first arm 55 and the second arm 56 are each a bent plate-shaped body made of synthetic resin. The material of the first arm 55 and the second arm 56 is preferably made of synthetic resin that is easy to process, but it is not limited to synthetic resin as long as the material does not damage the side surface of the container 3. In addition, in the container inspection device 1, it is preferable that the member that is in contact with the surface of the container 3 is made of a material that is not scratched like the first arm 55 or the like, and other members can be made of metal used in machinery. And other materials.

The first arm 55 is located at a position higher than 1/2 of the total height H of the container 3 stopped at the first discharge portion 30, that is, the first height H1. The second arm is located at a position lower than 1/2 of the full height H of the container 3, that is, the second height H2. In addition, the first pushing mechanism 60 pushes the container 3 toward the first conveyor 40 at a height between the first height H1 of the first arm 55 and the second height H2 of the second arm 56. The self-standing stability of the container 3 is ensured by the first arm 55 at the position of the upper half of the full height H of the container 3 and the second arm 56 at the position of the lower half of the container 3, and by making the first push out The mechanism 60 pushes out the container 3 between the first arm 55 and the second arm 56 and can move the container 3 to the first conveyor 40 outside the peripheral edge 14 more reliably. The height of the ejection plate 65 of the first ejection mechanism 60 is set at the height of the center of gravity of the container 3 in order to improve the self-standing stability of the container 3. In addition, when one arm is provided for each rotation axis, the first ejection mechanism 60 preferably ejects the container 3 from approximately the same height as the arm.

The free ends 552 of the first arm 55 and the second arm 56 are located closer to the receiving portion 16 side of the first discharge portion 30 than the fixed end 550 in the closed state. In other words, the free end 552 is located closer to the accommodating portion 16 stopped at the first discharge portion 30 than the virtual straight line connecting the first rotating shaft 53 and the second rotating shaft 54 in the closed state. By positioning the free end 552 at a position close to the receiving portion 16, the container 3 can be more reliably held in the receiving portion 16 in the closed state. Therefore, in the closed state, the fixed end 550 is located farther from the receiving portion 16 than the free end 552. By positioning the fixed end 550 at a position away from the accommodating portion 16, the container 3 and the fixed end 550 that are transported by the rotation of the first star wheel 10 can be prevented from contacting.

The first interval W1 can be adjusted by the first interval adjustment mechanism 58 according to the full width W of the container 3. The first interval adjustment mechanism 58 includes an operating lever 580 and two sets of ball screw mechanisms 582. In the ball screw mechanism 582, the screw shaft is shared, and the operating rod 580 is rotated to rotate the screw shaft, so that the two electric motors 57 fixed to the nut move closer to each other or move apart. Therefore, according to the first interval adjusting mechanism 58, the first interval W1 between the first rotating shaft 53 and the second rotating shaft 54 fixed to the electric motor 57 can be changed.

The second interval W2 can be changed according to the overall height H of the container 3 and the vertical weight arrangement (distribution) of the container 3. Long holes 59 extending in the vertical direction are formed in the first rotating shaft 53 and the second rotating shaft 54. The fixed end 550 is fixed in the long hole 59 by a mounting bolt. By loosening the mounting bolt of the fixed end 550 and moving the mounting bolt along the long hole 59, the first arm 55 and the second arm 56 can be moved along the long hole 59. For example, when the overall height H of the container 3 becomes higher, the first arm 55 and the second arm 56 are moved upward, and when the overall height H of the container 3 becomes lower, the first arm 55 and the second arm 56 are moved downward.

In addition, the second holding mechanism 52 in the second discharge portion 32 shown in FIGS. 1 and 3 basically has the same structure as the first holding mechanism 50, and is switched between the closed state and the open state. In the open state, the second pushing mechanism 62 acts on the container 3 in the second discharge portion 32 to push the container 3 out in the second direction D2 and move on the second conveyor 42. Since the first rotating shaft 53, the second rotating shaft 54, the first arm 55, the second arm 56, and the electric motor 57 of the second holding mechanism 52 have the same structure and function as each member of the first holding mechanism 50, Therefore, repeated descriptions are omitted.

3. Launch agency Use Fig. 1 to Fig. 3 to explain the pushing mechanism. In the container inspection device 1 of the present embodiment, the ejection mechanism includes the first ejection mechanism 60 and the second ejection mechanism 62, but since the basic structure is the same, the first ejection mechanism 60 is mainly described.

As shown in FIGS. 1 to 3, the first ejection mechanism 60 includes a support portion 64 erected on the machine table 2 and an ejection plate 65 supported by the support portion 64. The ejection plate 65 moves forward and backward with respect to the container 3 stopped at the first discharge part 30. The second ejection mechanism 62 includes an ejection plate 65 supported by the support portion 64. The ejection plate 65 moves forward and backward with respect to the container 3 stopped at the second discharge part 32. By supporting the ejection plate 65 to stabilize the forward and backward movement of the ejection plate 65 of the support portion 64, the self-standing stability of the container 3 can be improved.

The ejection plate 65 of the first ejection mechanism 60 is in contact with the container 3 of the first ejection portion 30. The ejection plate 65 of the first ejection mechanism 60 is constantly pushed in the first direction D1. The first ejection mechanism 60 brings the first holding mechanism 50 into contact with the container 3 being transported toward the first discharge portion 30 in the closed state to retract the ejection plate 65, and the first holding mechanism 50 turns into the open state. The ejection plate 65 is advanced in the first direction D1 to eject the container 3 from the accommodating portion 16. By constantly pushing the container 3 in the discharge direction (the first direction D1 and the second direction D2) by the eject plate 65, the container 3 can be discharged quickly.

As shown in FIG. 1, in the first star wheel 10, a first through hole 11 penetrating the upper and lower sides including the rotation center 5 is formed. As shown in FIG. 3, the second star wheel 12 is formed with a second through hole 13 penetrating the upper and lower sides including the rotation center 5. The support portion 64 is a cylindrical rod that penetrates the first through hole 11 and the second through hole 13 and is erected on the machine table 2. The lower end of the support portion 64 is fixed to the machine table 2. The first star wheel 10 and the second star wheel 12 rotate around the support portion 64, and the support portion 64 does not rotate.

The mounting plate 69 a extending in the horizontal direction is fixed in the supporting portion 64. The mounting plate 69a can move in the vertical direction along the support portion 64, and the height of the ejecting plate 65 can be adjusted by changing the height of the mounting plate 69a. Two sliding plates 69b are fixed to the mounting plate 69a. The sliding plate 69b loosens the fixing bolt by rotating the knob 69c, and is movable back and forth on the mounting plate 69a along the long hole provided in the sliding plate 69b. By moving the sliding plate 69b back and forth, it is possible to adjust the position of how much the push plate 65 protrudes toward the receiving portion 16. The ejection plate 65 is disposed so as to protrude toward the housing section 16 through two ejection arms 68a and 68b extending from the front end of the sliding plate 69b toward the housing section 16 (container 3) side.

The ejection plate 65 is constantly pushed in the direction protruding into the receiving portion 16. The pushing-out arm 68a and the pushing-out arm 68b are mounted on the sliding plate 69b through the pushing member 66a and the pushing member 66b. The urging member 66a urges the ejector arm 68a to the sliding plate 69b in the direction of right rotation in Figure 3, and the urging member 66b urges the ejector arm 68b to the sliding plate 69b in the direction of left rotation in Figure 3. force. Therefore, the front ends of the ejection arm 68a and the ejection arm 68b are constantly pushed toward each other. The tip of the ejection arm 68a is rotatably fixed to the ejection plate 65. An elongated hole 65a is opened in the ejection plate 65, and the elongated hole 65a accommodates a cam follower 67 provided at the front end of the ejection arm 68b so that the cam follower 67 can move along the elongated hole 65a.

In the state where the container 3 is not accommodated in the accommodating portion 16, as shown in the second discharge portion 32 in FIG. Section 16 was pushed out.

The ejection plate 65 has a chamfered portion 65b on the side conveyed toward the container 3 by the second star wheel 12. The chamfered portion 65b has a function of contacting the body portion of the container 3 being conveyed and pushing the push plate 65 back toward the sliding plate 69b. The pushing plate 65 pushed back is constantly pushing the container 3 out in the first direction D1 by the pushing members 66a and 66b. In addition, the container 3 is positioned on the first conveyor 40 that is constantly driven toward the first direction D1, and the bottom of the container 3 is in sliding contact with the first conveyor 40.

In the first discharge portion 30 in Figure 3, the first arm 55 (and the second arm 56) of the first holding mechanism 50 is in the closed state, and the contact portion 554 of the first arm 55 is in contact with the container 3 and resists pushing out The pushing force of the plate 65 holds the container 3 in the receiving portion 16.

If the first arm 55 is moved to the position shown by the dotted line in Fig. 3 and becomes the open state, the container 3 is pushed out in the first direction D1 by the push plate 65, and rides on the first conveyor 40 toward Move in the first direction D1. Since the second arm 56 shown in Fig. 2 arranged under the first arm 55 also operates in the same manner as the first arm 55, the container 3 can be more stably maintained in a state in which the self-standing state of the container 3 can be The first conveyor 40 moves.

4. Modifications The container inspection apparatus 1a of a modification is demonstrated. Fig. 4 is a partial enlarged view of a plan view of the container inspection device 1a of the modification, Fig. 5 is a side view of the container inspection device 1a of the modification, and Fig. 6 is the first discharge portion 30 of the container inspection device 1a of the modification Rear view. Here, the same reference numerals are used for the same configuration as the container inspection apparatus 1 of the above-mentioned embodiment, and repeated descriptions are omitted. In addition, since the second discharge section 32 has the same structure as the first discharge section 30, only the first discharge section 30 will be described here. In Fig. 6, the container 3 is viewed from the side of the accommodating portion along the first direction D1, and therefore the display of the first pushing mechanism 600 and the like are omitted.

4.1. Keep the organization As shown in FIGS. 4-6, the container inspection apparatus 1a of a modification has the 1st holding mechanism 500 which faces the 1st discharge part 30 and is supported by the machine base 2. As shown in FIG.

The first holding mechanism 500 includes one arm 560 and an electric motor 570 that swings the arm 560. The electric motor 570 is, for example, a servo motor. The electric motor 570 is fixed to the machine table 2.

The arm 560 has a fixed end 561 fixed to the rotating shaft 530 of the electric motor 570 and a free end 562 on the opposite side of the fixed end 561. Between the fixed end 561 and the free end 562, there is a contact portion 564 that comes into contact with the side surface of the container 3 stopped at the first discharge portion 30. The free end 562 is located closer to the receiving portion 16 side of the first discharge portion 30 than the fixed end 561 in the closed state.

The rotating shaft 530 of the electric motor 570 is parallel to the first direction D1 in a plan view of FIG. 4 and is inclined upward toward the first discharge portion 30 from a side view of FIG. 5. The upward inclination is, for example, about 10 to 20 degrees inclination with respect to the horizontal plane. When the electric motor 570 is driven, the rotating shaft 530 rotates, the free end 562 is moved in an arc with the fixed end 561 as the center, and the arm 560 is swung. As shown in FIG. 6, since the arm 560 is horizontal in the closed state when viewed from the back and vertical in the open state, the swing angle is 90 degrees. The swing angle can be changed within a range that can reliably hold the container 3 in the closed state and does not interfere with the discharged container 3 in the open state.

In FIGS. 4 to 6, the opening motion of the arm 560 is indicated by a dotted arrow. By driving the electric motor 570, the arm 560 is swung upward about the rotating shaft 530, and the free end 562 is moved upward while moving away from the first discharge portion 30. Thus, the first holding mechanism 500 changes from the closed state to the open state. The first holding mechanism 500 has a simple structure and can speed up the opening and closing of the arm 560. In addition, by tilting at least the rotating shaft 530 upward in this way, the free end 562 is not only moved upward, but by moving away from the first discharge part 30 while opening the action, which reduces the impact on the container 3 The upward lifting force can improve the self-standing stability of the container 3.

4.2. Launch agency As shown in Figures 4 and 5, the first pushing mechanism 600 is provided with a mounting plate 690 that is horizontally fixed to the support portion 64, and a sliding plate 692 that can move back and forth on the mounting plate 690 along the long hole 691 , And a push-out plate 650 extending from the sliding plate 692 toward the receiving portion 16 (container 3) side.

The sliding plate 692 includes a rail 693 extending in a direction perpendicular to the first direction D1, and a guide 694 extending along the first direction D1. The track 693 is formed with a groove. The guide 694 has a plate shape protruding from the upper surface of the sliding plate 692 and extending along the first direction D1.

The ejection plate 650 has a plate shape extending along the first direction D1, and includes a contact plate 651 at the front end, a sliding groove 653 at the rear end, and an urging member 660 on the upper surface.

The contact plate 651 is made of a material that does not scratch even if it comes into contact with the container, for example, made of synthetic resin, and has a chamfered portion 652 on the carrying-in side of the container 3.

The sliding groove 653 is a notch groove opened at the rear end of the eject plate 650 and is formed to extend along the first direction D1. The guide 694 is inserted into the sliding groove 653, and the sliding groove 653 is slidably contacted to the side of the guide 694 to move the ejection plate 650 forward and backward along the first direction D1. The ejection plate 650 is held between the upper surface of the sliding plate 692 and the pressing plate 695 fixed on the guide 694. Therefore, the upper and lower sides of the push plate 650 are guided by the sliding plate 692 and the pressing plate 695, and are guided by the guide 694 in a direction perpendicular to the first direction D1 to move forward and backward.

The urging member 660 includes an ejection arm 680 that urges the sliding plate 692 in the left-rotation direction in FIG. 3 and a cam follower 670 attached to the tip of the ejection arm 680. The cam follower 670 is movable along the rail 693 in a direction perpendicular to the first direction D1. Therefore, the urging member 660 constantly urges the ejection arm 680 so that the cam follower 670 moves upward in FIG. 4. As a result, the ejection plate 650 to which the urging member 660 is fixed is opposed to the sliding plate 692. Push out the ground in the first direction D1 from time to time.

In the state where the container 3 is not housed in the accommodating portion 16, the contact plate 651 of the ejection plate 650 is pushed out to the accommodating portion 16. When the first star wheel 10 and the second star wheel 12 rotate and the container 3 is carried into the first discharge portion 30, the chamfered portion 652 will initially contact the side surface of the container 3. As the container 3 approaches the first discharge portion 30, the ejection plate 650 is retracted while sliding the chamfered portion 652. At this time, the cam follower 670 rotates within the rail 693, and the sliding groove 653 is guided by the guide 694 to the state shown in FIG. 4.

When the electric motor 570 is driven to move the first holding mechanism 500 from the closed state to the open state, the pushing member 660 rotates the pushing arm 680 to the left to rotate the cam follower 670 in the rail 693 upward in FIG. 4. Thereby, the ejector plate 650 is ejected in the first direction D1 along the guide 694, and the contact plate 651 ejects the container 3 on the first conveyor 40 by pushing the side surface of the container 3 quickly.

5. Lifting part The elevating section 100 will be described using Fig. 1 and Fig. 7 to Fig. 9. FIG. 7 is a front view of the imaging unit 28 of this embodiment which is the container inspection device 1 in the inspection position, and FIG. 8 is a front view of the imaging unit 28 of this embodiment which is the container inspection device 1 in the maintenance position. FIG. 9 is a plan view of the lift unit 100. In FIGS. 7 and 8, the mechanisms on the machine base 2 such as the first star wheel 10 and the second star wheel 12 are omitted.

As shown in FIG. 1, the inspection unit 20 is arranged along the peripheral edge 14 of the first star wheel 10. The frame 110 is arranged to surround the machine 2. The frame 110 is formed by welding angle steel pipes. The frame 110 is arranged separately from the machine 2.

As shown in FIG. 7, the frame 110 is installed on the same installation surface as the machine table 2, and the container 3 extends upward to a position higher than the height to be conveyed. A lifting part 100 is provided at the upper end of the frame 110.

The inspection unit 20 includes: a light emitting unit 27 that is suspended from the frame 110 and emits light to the container 3; and an imaging unit that is suspended from the frame 110 and irradiated by the light of the light emitting unit 27 to take an image of the container 3 28. The imaging unit 28 is arranged to face the light emitting unit 27 with the container 3 interposed therebetween. When the imaging unit 28 captures images by reflected light from the container 3, the imaging unit 28 may be provided on the light emitting unit 27 side.

The light emitting unit 27 and the imaging unit 28 are fixed to the frame 110. The light emitting unit 27 is suspended from the frame 110 and emits light to the container 3. The imaging unit 28 is suspended from the frame 110 and takes an image of the container 3 irradiated with the light of the light emitting unit 27.

In this way, because the frame 110 is separated from the machine table 2 that vibrates due to the rotation of the first star wheel 10 and the second star wheel 12, the vibration of the imaging unit 28 is suppressed, and the imaging unit 28 can perform high precision Portrait photography.

As shown in FIGS. 7-9, the container inspection device 1 has an elevation unit 100 above the conveyance path of the container 3. The lifting unit 100 lifts the light emitting unit 27 and the imaging unit 28 with respect to the container 3. The elevator unit 100 is on the frame 110 and includes an elevator motor 120, a ball screw mechanism 124, a belt 121 and a gear box 122 that transmit the driving force of the elevator motor 120 to the ball screw mechanism 124, and a ball screw mechanism 124 3 guides 126 hanging from the frame 110 in parallel with the threaded shaft 125. The lifting motor 120 is an electric motor.

The elevating unit 100 is located at the inspection position shown in Fig. 7 that matches the height of the container 3 carried by the first star wheel 10 and the second star wheel 12, and at the 8th position higher than the inspection position. Between the maintenance positions shown in the figure, the light emitting unit 27 and the imaging unit 28 can be raised and lowered. The light emitting unit 27 and the imaging unit 28 are integrated, and when the screw shaft 125 is rotated by the driving of the elevating motor 120, the light emitting unit 27 and the imaging unit 28 are guided by the guide 126 to move up and down. If maintenance is performed with the light-emitting part 27 and the imaging part 28 at the inspection position shown in Fig. 7, the first push-out mechanism 60 and the first push-out mechanism 60 and the second fixed to the first star wheel 10 and the second star wheel 12 and the support part 64 2 The maintenance work of the pushing mechanism 62 is not easy to perform. In this regard, if the light-emitting unit 27 and the imaging unit 28 are provided in the maintenance position shown in FIG. 8, the workability inside the device can be further improved.

Conventionally, the light emitting unit 27 and the imaging unit 28 are often removed from the container inspection device 1 every time maintenance work is performed. However, if the light emitting unit 27 and the imaging unit 28 are raised at the maintenance position, they do not need to be removed. Therefore, the work time for returning the light emitting unit 27 and the imaging unit 28 to the inspection position after maintenance can be shortened. In addition, the light emitting unit 27 and the like are raised by the elevating unit 100, so that the operator can easily inspect and repair the container inspection apparatus 1, and the operator can easily access parts and the like. In this way, by shortening the time required for maintenance, the time for stopping the production line can also be shortened, and as a result, the productivity of the container 3 can be improved. Maintenance includes, for example, the adjustment of the respective operating parts of the first pushing mechanism 60 and the like, and the appearance switching operation when the style design of the container 3 is changed. The shape switching operation is a handover operation of parts related to the loading and unloading (support processing) of the container 3, and the operation takes time especially. In the appearance switching operation, in the state where the light emitting part 27 and the like are raised by the lifting part 100, for example, after the support part 64 is removed from the machine table 2, the first star wheel 10 and the second star wheel 12 are taken together Next, install the new first star wheel 10 and the second star wheel 12 components designed to match the style of the changed container 3. After this installation, when the light emitting unit 27 and the like are returned to the inspection position by the lifting unit 100 again, the appearance switching operation is completed. In addition, by using the lifter 100, the time required for the appearance switching operation can be reduced to less than half compared to the conventional device without the lifter 100, which has also been confirmed by experiments by the inventors.

The elevating unit 100 may further include an operating lever 130 for elevating. The lifting operation lever 130 is suspended from the frame 110 and is arranged above the container 3. The lifting operation lever 130 is connected to the belt 121 through a pulley. By rotating the lifting operation lever 130, the ball screw mechanism 124 can be driven through the belt 121 and the gear box 122 to lift the light emitting unit 27 and the imaging unit 28 up and down. With the lifting operation lever 130, even if the lifting motor 120 fails and the lifting motor 120 is not supplied with power, the light emitting unit 27 and the imaging unit 28 can be raised and lowered.

The elevating unit 100 is not limited to the ball screw mechanism 124, and instead of the ball screw mechanism 124, a known linear motion mechanism for elevating the light emitting unit 27 and the imaging unit 28 may be used.

The present invention is not limited to the above-mentioned embodiment, and can be further variously modified, and includes a configuration (structure) that is substantially the same as the configuration (structure) described in the embodiment. Here, the "same structure (structure)" means a structure (structure) with the same function, method, and result, or a structure (structure) with the same objective effect. In addition, the present invention includes a configuration (structure) in which non-essential parts of the configuration (structure) described in the embodiment are replaced. In addition, the present invention includes a structure that can achieve the same effects as the structure (structure) described in the embodiment, or a structure (structure) that can achieve the same purpose. In addition, the present invention includes the configuration (structure) described in the embodiment with the addition of known technology.
