[0006] Technical problem to be solved by the invention

[0007] Patent Document 1 describes a mechanism for stably holding containers with different container diameters and conveying them at high speed. However, the conveying device described in Patent Document 1 is a mechanism for conveying along a circular path. Therefore, when conveying at a distance where the conveying source and the conveying destination are far from each other, there is a problem that multiple container holding and conveying devices must be provided.

[0008] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a conveying device capable of conveying even when a conveyance source and a conveyance destination are far away from each other.

[0009] Technical solutions to solve problems

[0010] In order to solve the above-mentioned problems, the conveyor belt of the present invention is used in manufacturing equipment for conveying containers of different types such as ampoules with different diameters. The conveyor belt comprises a lower belt conveying block supporting the upstream main body and bottom surface of the container to be conveyed and an upper belt conveying block supporting the downstream main body. By adjusting the interval between the lower belt conveying block and the upper belt conveying block before and after the container, the containers with different diameters can be conveyed.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[0025] The present invention provides a conveying device capable of stably holding containers such as syringes, ampoules, and vials having different diameters and conveying them linearly.

[0026] Hereinafter, the embodiments will be described using the drawings.

[0027] <<Implementation Method 1>>

[0028] Figure 1 A plan view showing a conveyor belt B of an embodiment of an inspection machine to which the present invention is applied.

[0029] Figure 2A express Figure 1 I direction stereogram. Figure 2B express Figure 2A Enlarged view of Part II. Figure 2C express Figure 2B A top view in direction III.

[0030] Figure 1 The conveyor B of the illustrated embodiment has a function of sequentially delivering the containers 80 held by an upstream star wheel 91 in an inspection machine of a manufacturing facility to a downstream star wheel 92 .

[0031] The conveyor belt B connects the upstream star wheel 91 and the downstream star wheel 92 in a straight line.

[0032] Figure 2A The conveyor belt B shown is composed of a driving side pulley portion 10, a driven side pulley portion 50, an upper profile belt (not a flat belt, but a conveyor belt with a profile shape) 12 mounted on the pulley portions (10, 50) and a lower profile belt 22.

[0033] The upper contour band 12 and the lower contour band 22 are configured as two layers, one above the other.

[0034] The lower profile belt 22 is provided with a plurality of rear conveying blocks 21 (see Figure 2B ). A plurality of front conveying blocks 11 are provided on the upper contour belt 12.

[0035] like Figure 2A As shown, the lower profile belt 22 is mounted on the lower pulley 23 .

[0036] The upper profile belt 12 is mounted on the upper pulley 13 .

[0037] like Figure 1 , Figure 2A As shown, the container 80 held by the upstream star wheel 91 is sandwiched between the front conveying block 11 and the rear conveying block 21 and conveyed. After being conveyed, the container 80 is transferred to the downstream star wheel 92 (refer to Figure 1 ).

[0038] According to this structure, by changing the relative position (phase shift) of the lower belt pulley 23 and the upper belt pulley 13, the interval between the rear conveying block 21 and the front conveying block 11 is changed, and the containers 80 with different diameters are clamped and conveyed by the rear conveying block 21 and the front conveying block 11. That is, the interval between the front conveying block 11 (first conveying block) and the rear conveying block 21 (second conveying block) is changed according to the diameter of the container.

[0039] Figure 3 express Figure 1 A cross-sectional view of the driving side pulley portion 10 on the driving shaft side in FIG. Figure 1 IV-IV cross-sectional view of .

[0040] The driving side pulley portion 10 is configured to include a lower pulley 23 , an upper pulley 13 , and a profile change plate 34 .

[0041] like Figure 2A , Figure 2B As shown, the rear conveying block 21 for supporting the container 80 is mounted on the lower profile belt 22. The profile belt 22 is hung on the lower pulley 23.

[0042] The front conveying block 11 for supporting the container 80 is mounted on the upper profile belt 12. The upper profile belt 12 is hung on the upper pulley 13.

[0043] like Figure 2C As shown, Figure 1 The front conveying block 11 shown is held so that an inclined surface 11 k having an inclination of an angle θ3 (=45 degrees) in a plan view contacts the front side (the side in the advancing direction) of the container 80 .

[0044] The rear conveyance block 21 is held so that a flat surface 21 k having no inclination in a plan view contacts the rear side (the side opposite to the traveling direction) of the container 80 .

[0045] The front conveying block 11 uses an inclined surface 11k with an angle θ (= 45 degrees) when viewed from above to hold the container 80. Therefore, when using the non-inclined flat surface 21k of the rear conveying block 21 to hold containers 80 of different sizes, even if there are some dimensional errors, the front conveying block 11 can absorb the errors using the inclined surface 11k with an angle θ3 (= 45 degrees).

[0046] In this way, even if the container 80 is different in size, the inclined surface 11k having the inclined angle θ3 (=45 degrees) of the front conveying block 11 can be used (see Figure 2C ) and the flat surface 21k without inclination of the rear side conveying block 21 are maintained for reliable conveying.

[0047] <Driving Side Pulley 10>

[0048] Figure 3The change plate 34 of the driving side pulley portion 10 shown is a component that changes the relative setting angle between the lower pulley 23 on which the lower profile belt 22 is hung and the upper pulley 13 on which the upper profile belt 12 is hung according to the size of the container 80 being transported (details will be described later). By changing the relative setting angle between the lower pulley 23 and the upper pulley 13, the relative position of the lower profile belt 22 and the upper profile belt 12 can be changed, and the interval s1 between the front conveying block 11 and the rear conveying block 21 can be changed. The center position of the container 80 held by the front conveying block 11 and the rear conveying block 2 is approximately the same position. The existing upstream star wheel 91 and downstream star wheel 92 can be applied.

[0049] Thus, by changing the relative position of the lower profile belt 22 and the upper profile belt 12 (changing the phase), the interval s1 between the front conveying block 11 and the rear conveying block 21 can be changed, and containers 80 having different container diameters 80k can be conveyed.

[0050] Thus, containers 80 having different container diameters 80k (=interval s1) can be held and conveyed by the front conveying block 11 and the rear conveying block 21. Therefore, mold change plates 34 are prepared in the same number as the sizes of the containers 80 to be conveyed. For example, when there are two sizes of containers 80, two types of mold change plates 34 are prepared. Alternatively, when there are three sizes of containers 80, three types of mold change plates 34 are prepared.

[0051] Figure 3 The upper pulley 13 shown rotates about the drive shaft 31 via bearings 14A, 14B.

[0052] The lower pulley 23 rotates around the drive shaft 31 via bearings 24A and 24B.

[0053] The driving shaft 31 has a larger diameter 31 b below the lower pulley 23 , and a step portion 31 b 1 is formed.

[0054] The lower pulley 23 is placed on the step portion 31 b 1 of the larger diameter 31 b of the drive shaft 31 .

[0055] A flat annular collar 35 as a spacer is arranged between the upper pulley 13 and the lower pulley 23. The upper pulley 13 is arranged on the collar 35. A set collar 32 in the shape of an inverted truncated cone is arranged on the upper pulley 13. The set collar 32 is threaded with an internal thread 32n, which is screwed with a headless screw 32b that presses the drive shaft 31.

[0056] During assembly, the fixing ring 32 presses the lower components (upper pulley 13, collar 35, lower pulley 23) downward. The headless screw 32b is screwed into the internal thread 32n of the fixing ring 32, and the fixing ring 32 is fixed to the drive shaft 31 by pressing the drive shaft 31.

[0057] Here, the fixing ring 32 presses the lower components (the upper pulley 13 , the collar 35 , and the lower pulley 23 ) downward to press and fix the bearings 14A, 14B, 24A, and 24B.

[0058] Figure 3 The drive shaft 31 shown has the upper pulley 13 arranged at the upper portion and the lower pulley 23 arranged at the lower portion, and is supported by a bracket 38 via an upper bearing 36A and a lower bearing 37B.

[0059] The upper side of the drive shaft 31 is fixed to the bracket 38 via a bearing 36A disposed below the lower pulley 23. The lower side of the drive shaft 31 is fixed to the bracket 38 via a bearing 36B and a lock washer 37.

[0060] The lower part of the drive shaft 31 is connected to the torque limiter 41 and the timing pulley 42 through the clamp ring 39 and the component 40. By loosening the clamp ring 39, the angle of the drive shaft 31 configured with the upper pulley 13 and the lower pulley 23 can be adjusted, and the container 80 can be adjusted at the same time. Figure 1 The upstream star wheel 91 and the downstream star wheel 92 are shown in FIG.

[0061] <Structure of the upper pulley 13, the lower pulley 23 and the change plate 34 for containers 80 having different container diameters>

[0062] Figure 4A The diagram shows a transport container with a small container diameter of 80 k (see Figure 1) viewed from above. Figure 2C ) is a schematic diagram of the upper pulley 13, the lower pulley 23 and the change plate 34 of the container 80.

[0063] Figure 4B Schematic diagram showing the upper pulley 13, the lower pulley 23 and the mold change plate 34 for conveying a container 80 having a large container diameter 80k as viewed from above is shown in FIG.

[0064] In the conveyor B that transports containers 80 having different container diameters 80k, the pattern changing plate 34 has a reference pin insertion hole 34a through which the reference pin 25 is inserted and a pulley fixing pin insertion hole 34b through which the pulley fixing pin 15 is inserted.

[0065] The reference pin 25 integrated with the lower pulley 23 is inserted through the upper pulley 13 and the change plate 34. Figure 4A , Figure 4B As shown, the position of the pulley fixing pin 15 inserted through the mold changing plate 34 and the upper pulley 13 is changed with the reference pin 25 as a reference, thereby changing the relative position of the lower pulley 23 and the upper pulley 13.

[0066] Thus, by changing the interval between the rear conveyance block 21 and the front conveyance block 11 , the containers 80 having different container diameters 80k are sandwiched and conveyed by the rear conveyance block 21 and the front conveyance block 11 .

[0067] like Figure 4A As shown, for a container 80 having a small container diameter 80k, the angle between the lower belt pulley 23 and the upper belt pulley 13 is set to θ1, and the interval s1 between the rear conveying block 21 and the front conveying block 11 is reduced via the lower contour belt 22 and the upper contour belt 12 (refer to Figure 1 ), and is clamped and transported by the rear conveying block 21 and the front conveying block 11.

[0068] like Figure 4B As shown, for a container 80 having a large container diameter 80k, the angle between the lower belt pulley 23 and the upper belt pulley 13 is formed to be θ2, and the interval s1 between the rear conveying block 21 and the front conveying block 11 is increased via the lower contour belt 22 and the upper contour belt 12 (see Figure 1 ), and is clamped and transported by the rear conveying block 21 and the front conveying block 11.

[0069] Hereinafter, the structures of the upper pulley 13, the lower pulley 23 and the pattern changing plate 34 will be described in detail.

[0070] <Structure of upper pulley 13, lower pulley 23 and change plate 34>

[0071] Figure 5 An exploded perspective view showing the upper pulley 13 , the lower pulley 23 and the profile changing plate 34 .

[0072] Figure 6 A perspective view showing the assembly process of the upper pulley 13 , the lower pulley 23 and the profile change plate 34 .

[0073] exist Figure 5 The lower pulley 23 shown has a reference pin 25 fixed thereto extending upward to define the relative position of the upper pulley 13 and the mold change plate 34 .

[0074] A shaft hole 23 o through which the drive shaft 31 is inserted is provided at the center of the lower pulley 23 .

[0075] The upper pulley 13 is provided with a central shaft hole 13o, a positioning hole 13a, and a fan-shaped movable region long hole 26 penetrating vertically. A driving shaft 31 is inserted through the shaft hole 13o.

[0076] A pulley fixing pin 15 for positioning the lower pulley 23 can be inserted into the positioning hole 13 a .

[0077] The movable region long hole 26 is a hole through which the reference pin 25 is inserted, and a region where the upper pulley 13 is relatively movable with respect to the lower pulley 23 is bored.

[0078] For each container size 80, such as Figure 4A , Figure 4B As shown, the relative position of the lower pulley 23 and the upper pulley 13 changes, so the position where the reference pin 25 is inserted through the fan-shaped movable region long hole 26 of the upper pulley 13 varies depending on the size of the container 80 .

[0079] Since the upper pulley 13 has the movable region elongated hole 26 , the reference pin 25 of the lower pulley 23 is inserted through the movable region elongated hole 26 of the upper pulley 13 , so that the upper pulley 13 is relatively rotatable with respect to the lower pulley 23 .

[0080] like Figure 5 , Figure 6 As shown, the reference pin 25 of the lower pulley 23 (lower reference pin 25 ) is inserted into the movable region long hole 26 of the upper pulley 13 and the reference pin insertion hole 34 a of the mold change plate 34 .

[0081] The pulley fixing pin 15 that changes the position of the upper pulley 13 relative to the lower pulley 23 is arranged at a different position on the upper pulley 13 relative to the lower pulley 23 depending on the size of the container 80 .

[0082] Therefore, if Figure 4A , Figure 4B As shown in FIG. 1 , the position of the pulley fixing pin 15 arranged on the upper pulley 13 is changed by using a change plate 34 that changes the position of the pulley fixing pin 15 .

[0083] <Changeover plate 34>

[0084] like Figure 5 , Figure 3 As shown, the change plate 34 is a component that matches the key 33 of the drive shaft, the upper pulley fixing pin 15, and the lower reference pin 25. In other words, the change plate 34 is installed to match the key 33 of the drive shaft, the upper pulley fixing pin 15 inserted through the upper pulley 13, and the lower reference pin 25 fixed to the lower pulley 23.

[0085] The change plate 34 determines the position of the lower pulley 23 and the upper pulley 13 based on the key 33 of the drive shaft, so that Figure 1 The types of the upstream star wheel 91 and the downstream star wheel 92 shown adjust the delivery timing of the container 80.

[0086] like Figure 5As shown, in the mold change plate 34, the shaft key insertion hole 34o, the reference pin insertion hole 34a and the pulley fixing pin insertion hole 34b are provided in a through-going manner.

[0087] In the mold change plate 34, regardless of the size of the container 80, the positions of the shaft key insertion hole 34o and the reference pin insertion hole 34a do not change.

[0088] The pulley fixing pin 15 is inserted through the pulley fixing pin insertion hole 34 b of the mold changing plate 34 , and the pulley fixing pin 15 is inserted through the positioning hole 13 a of the upper pulley 13 .

[0089] So, if Figure 4A , Figure 4B As shown, the pulley fixing pin insertion hole 34 b of the change plate 34 changes the position of the upper pulley 13 relative to the lower pulley 23 according to the size of the container 80 , and thus the position changes according to the size of the container 80 .

[0090] That is, the pulley fixing pin 15 makes the position of the upper pulley 13 different relative to the lower pulley 23. Figure 2A The relative positions of the lower pulley 23 and the upper pulley 13 shown are different, and the relative positions of the lower profile belt 22 hung on the lower pulley 23 and the upper profile belt 12 hung on the upper pulley 13 can be changed. In this way, the interval s1 (refer to Figure 1 ) is different, and can maintain a container diameter of 80k (refer to Figure 2C ) for transporting in different containers 80.

[0091] Specifically, for each container diameter 80k (refer to Figure 2C ) Prepare the mold change plate 34. Then, for each mold change plate 34, set the position where the pulley fixing pin 15 is arranged on the upper pulley 13.

[0092] In this way, the position of the pulley fixing pin 15 disposed on the upper pulley 13 is determined by each change plate 34. As a result, the phase (relative position) of the lower pulley 23 and the upper pulley 13 is changed. Figure 2C ) different containers 80, so that the interval s1 between the rear conveying block 21 and the front conveying block 11 (refer to Figure 1 ) are different, such as Figure 2B As shown, the rear conveying block 21 and the front conveying block 11 are used to hold containers 80 having different container diameters 80k, such as Figure 1As shown by arrow α11, the container 80 is sequentially conveyed from the upstream star wheel 91 to the downstream star wheel 92. The phase of the upper pulley 13 and the lower pulley 23 is determined by installing the change plate 34, and the container 80 with a container diameter 80k that can be conveyed by the upper profile belt 12 and the lower profile belt 22 is determined.

[0093] Here, the center position 80c of the container 80 held by the front conveying block 11 and the rear conveying block 21 (see Figure 2C , Figure 1 ) are substantially the same position. Thus, this structure can also be applied when the upstream side star wheel 91 and the downstream side star wheel 92 are replaced.

[0094] <Assembly of upper pulley 13, lower pulley 23 and change plate 34>

[0095] The assembly of the upper pulley 13, the lower pulley 23 and the mold change plate 34 having the above-mentioned structure will be described.

[0096] like Figure 5 As shown, the drive shaft 31 is inserted through the shaft hole 23o of the lower pulley 23. Then, the drive shaft 31 inserted through the shaft hole 23o of the lower pulley 23 is inserted through the shaft hole 13o of the upper pulley 13, and the reference pin 25 of the lower pulley 23 through which the drive shaft 31 is inserted is inserted through the movable region long hole 26 of the upper pulley 13 (refer to Figure 6 At this time, the reference pin 25 of the lower pulley 23 moves in the movable region long hole 26 of the upper pulley 13 , and the pulley fixing pin 15 can be inserted into the positioning hole 13 a of the upper pulley 13 .

[0097] Next, the pulley fixing pin 15 is inserted into the positioning hole 13 a of the upper pulley 13 from above.

[0098] Then, if Figure 6 , Figure 3 As shown, the drive shaft 31 and the key 33 inserted in the lower pulley 23 and the upper pulley 13 are inserted into the shaft key insertion hole 34o of the mold change plate 34, and the reference pin 25 of the lower pulley 23 is inserted into the reference pin insertion hole 34a of the mold change plate 34. In addition, the pulley fixing pin 15 inserted in the upper pulley 13 is inserted into the pulley fixing pin insertion hole 34b of the mold change plate 34 (see Figure 3 ).

[0099] Then, the upper profile belt 12 is stretched over the upper pulley 13 of the driving pulley portion 10 and the driven pulley portion 50. Also, the lower profile belt 22 is stretched over the lower pulley 23 of the driving pulley portion 10 and the driven pulley portion 50.

[0100] In this way, the interval s1 between the rear conveying block 21 provided with the lower contour belt 22 of the container 80 and the front conveying block 11 provided with the upper contour belt 12 can be set.

[0101] As described above, the lower profile belt 22 is hung on the lower pulley 23. The upper profile belt 12 is hung on the upper pulley 13. Therefore, by determining the phase of the upper pulley 13 and the lower pulley 23, the size of the container 80 (container diameter 80k of the container 80) clamped by the rear conveying block 21 and the front conveying block 11 can be determined via the upper profile belt 12 and the lower profile belt 22.

[0102] Thus, the container 80 is sandwiched between the rear conveying block 21 of the profile belt 22 mounted on the lower stage and the front conveying block 11 of the profile belt 12 mounted on the upper stage according to the container diameter 80k.

[0103] The mold change plates 34 are prepared in accordance with the types of containers 80 to be conveyed having different container diameters 80.

[0104] Thus, by using the change plate 34 corresponding to the container diameter 80 of the container 80 , it is possible to perform high-precision positioning without requiring adjustment work.

[0105] <Driven Side Pulley 50>

[0106] Figure 7 A cross-sectional view showing the driven side pulley portion 50 of the conveyor belt B Figure 1 VV cross-section diagram.

[0107] A driven shaft 56 as a rotating shaft is provided on the driven side pulley portion 50. Bearings 53A and 53B that rotatably support the upper pulley 51 are fixed to the driven shaft 56. Bearings 54A and 54B that rotatably support the lower pulley 52 are fixed to the driven shaft 56.

[0108] The upper pulley 51 is connected to the driven shaft 56 via bearings 53A and 53B. The lower pulley 52 is connected to the driven shaft 56 via bearings 54A and 54B.

[0109] The upper parts of the lower pulley 52 and the upper pulley 51 are fixed by an annular fixing ring 57 as a spacer. The lower part of the driven shaft 56 contacts the resin member 55 at the contact surface 55s and slides on the contact surface 55s.

[0110] In this way, the lower pulley 52 and the upper pulley 51 are rotatably held by the lower resin member 55 and the upper fixing ring 57 .

[0111] <Driven Positioning Shaft 66 and Plate 62>

[0112] The conveyor belt B is provided with a driven positioning shaft 66 and a plate 62 as components for moving and adjusting the position of the driven shaft 56 .

[0113] A handle 68 for rotating the driven positioning shaft 66 is fixed. The driven positioning shaft 66 is threaded with an external thread 66m.

[0114] On the other hand, the driven shaft 56 and a trapezoidal nut 63 as a moved member are fixed to the plate 62 .

[0115] The plate 62 to which the trapezoidal nut 63 is fixed slides on the upper part of the base 61 guided by the guide rail 61a ( Figure 7 α12).

[0116] The upper part of the driven shaft 56 is fixed to the plate 62. An internal thread 63m is screwed on the trapezoidal nut 63. The internal thread 63m of the trapezoidal nut 63 can be screwed with the external thread 66m of the shaft 66. According to this structure, when the user turns the handle 68, the external thread 66m of the shaft 66 rotates, and the trapezoidal nut 63 moves due to the internal thread 63m screwed with the external thread 66m. The position of the plate 62 is changed by the movement of the trapezoidal nut 63, and the position of the driven shaft 56 fixed to the plate 62 is changed.

[0117] By tightening the rod 69, the plate 62 is fixed by the frictional force with the base 61. Specifically, by tightening the rod 69, the cam portion 69i of the rod 69 presses the driven positioning shaft 66 to lock the shaft 66.

[0118] Thus, the plate 62 is fixed due to the frictional force with the base 61 .

[0119] On the other hand, the rod 69 is loosened to unlock the handle 68. Then, when the handle 68 is rotated, the driven positioning shaft 66 rotates, and the trapezoidal nut 63 moves along the external thread 66m of the driven positioning shaft 66, so that the position of the driven shaft 56 relative to the base 61 can be changed.

[0120] As the driven shaft 56 moves, the lower portion of the driven shaft 56 slides on the contact surface 55s of the resin member 55. As the driven shaft 56 slides, the upper pulley 51 and the lower pulley 52 inserted through the driven shaft 56 move.

[0121] By moving the driven shaft 56 , the tension of the upper profile belt 12 and the lower profile belt 22 hung on the upper pulley 51 and the lower pulley 52 can be adjusted.

[0122] In addition, the upper contour tape 12 and the lower contour tape 22 stretched on the upper pulley 51 and the lower pulley 52 can be replaced, or new upper contour tape 12 and lower contour tape 22 can be stretched.

[0123] As described above, the conveyor belt B is equipped with a change plate 34 corresponding to the size of the container 80 (container diameter 80k). Figure 4A As shown, by changing the relative positions of the upper pulley 13 and the lower pulley 23, the interval s1 between the front conveying block 11 and the rear conveying block 21 can be easily changed (refer to Figure 1 ), conveying containers 80 with any container diameter.

[0124] When the conveyor belt B is running, the driving force of the synchronous pulley 42 is transmitted to Figure 3 The torque limiter 41, the component 40, the clamping ring 39, the drive shaft 31, the key 33 of the drive shaft, and the change plate 34 are shown. The drive is transmitted from the change plate 34 to the reference pin 25 and the pulley fixing pin 15. As a result, the upper pulley 13 and the lower pulley 23 rotate, and the front conveying block 11 mounted on the upper belt 22 and the rear conveying block 21 mounted on the lower belt 12 are driven synchronously, thereby conveying the container 80 from the upstream star wheel 91 to the downstream star wheel 92.

[0125] According to the above configuration, containers 80 having different container diameters 80k can be conveyed simply by matching the interval between the front conveying block 11 and the rear conveying block 21 to the container 80 .

[0126] Furthermore, it is possible to provide a conveyor belt B of a conveying device capable of performing linear conveying.
