[0002] Existing automated filling line equipment uses sampling weighing or manual removal methods for weighing. However, in some scenarios, it is necessary to detect the weight of each product while ensuring continuous production, and the existing equipment cannot meet such requirements. In addition, existing equipment usually can only extract a single product for detection through grippers or vacuum suction cups, and such a method not only has low production efficiency but also has a risk of leakage. Summary of the Utility Model
[0003] In view of the state of the above-mentioned existing technology, the present disclosure is made. The purpose of the present disclosure is to provide a weighing device and a filling machine that can overcome or mitigate at least one of the disadvantages described in the above background art.

When the guardrail is in the third position, the guardrail contacts the target object and the support plate is in the first position. When the guardrail is in the fourth position, the guardrail is separated from the target object and the support plate is in the second position.
[0009] In another alternative, the support plate is configured to move in a first direction to switch between the first position and the second position, and the guardrail is configured to move in a second direction to switch between the third position and the fourth position, and the first direction and the second direction are orthogonal to each other.

[0051] As Figure 1 shown, an embodiment of the present disclosure provides a weighing device 30.
[0052] As Figures 1 to 4 shown, the weighing device 30 may include one or more weighing sensors 32, one or more weighing seats 34, and a support plate 36. The weighing sensor 32 is used to weigh the weight of the target object 38. The weighing seat 34 is connected to the weighing sensor and is configured to be able to transfer the weight of the target object 38 to the weighing sensor 32. The support plate 36 is configured to be able to switch between a first position and a second position. When the support plate 36 is in the first position, the support plate 36 supports the target object 38, and the weighing seat 34 is separated from the target object 38. When the support plate 36 is in the second position, the support plate 36 is separated from the target object 38, and the weighing seat 34 supports the target object 38. In other words, when the support plate 36 is in the first position, the weight of the target object 38 is borne by the support plate 36, and the weighing sensor 32 does not measure the weight of the target object 38; when the support plate 36 is in the second position, the weight of the target object 38 is borne by the weighing seat 34, so that the weighing sensor 32 can measure the weight of the target object 38.
[0053] In the technical solution provided by the embodiments of the present disclosure, by making the support plate 36 and the weighing seat 34 cooperate with each other, the weighing device 30 can detect the weight of the target object 38 during continuous production, so that the weighing device 30 has a high production efficiency. In addition, during the process of measuring the weight, the target object 38 does not need to be extracted by, for example, a gripper or a suction cup, etc., so that the leakage of the contents of the target object 38 can be avoided.
[0054] In some examples, as Figure 1 shown, the target object 38 is a bottle-shaped packaging material, for example, it can be a vial.
[0055] In some examples, as Figure 2 shown, each weighing sensor 32 corresponds to a weighing seat 34.
[0056] In some examples, as Figure 1 shown, the support plate 36 is used to support multiple target objects 38 at the same time, and each weighing seat 34 is used to support one of the multiple target objects 38. In other words, each weighing seat 34 is used to transfer the weight of one target object 38 to the weighing sensor 32.
[0057] In some examples, as Figure 2 and Figure 4 shown, the support plate 36 is provided with one or more weighing holes 40. When the support plate 36 is in the second position, the weighing seat 34 passes through the support plate 36 via the weighing hole 40 to support the target object 38. In this way, the support plate 36 and the weighing seat 34 can be arranged more compactly, and the stroke required for the support plate 36 to switch between the first position and the second position is also smaller, which is beneficial to the miniaturization of the weighing device 30.
[0058] In some examples, when the support plate 36 is in the first position, the end of the weighing seat 34 for contacting the target object 38 is received in the weighing hole 40. In other words, the weighing seat 34 is received by the weighing hole 40 but does not pass through the support plate 36. In this way, the stroke of the support plate 36 can be further reduced. In some other examples, when the support plate 36 is in the first position, the weighing seat 34 can also leave the weighing hole 40.
[0059] In some examples, as Figure 2 and Figure 4 shown, when the support plate 36 is in the second position, multiple weighing seats 34 are received by the same weighing hole 40. In this way, the support plate 36 can be provided with fewer weighing holes 40, so that the weighing device 30 can have a lower manufacturing cost.
[0060] In some examples, as Figure 2 and Figure 4As shown, a plurality of weighing seats 34 are arranged side by side. The weighing holes 40 are oblong, and the length direction of the weighing holes 40 is parallel to the arrangement direction of the weighing seats 34.
[0061] In some examples, as Figure 2 and Figure 4 shown, when the support plate 36 is in the second position, a plurality of weighing holes 40 receive the same weighing seat 34. In this way, a single weighing hole 40 can have a smaller size, so that the support plate 36 can reliably support the target object 38.
[0062] In some examples, as Figure 2 and Figure 4 shown, the weighing seat 34 is provided with a plurality of teeth 62. When the support plate 36 is in the second position, the plurality of teeth 62 are respectively received by different weighing holes 40.
[0063] In some examples, as Figure 1 and Figure 4 shown, the weighing device 30 further includes a guardrail 42. The guardrail 42 is used to hold the target object 38 on the support plate 36 and is configured to be able to switch between a third position and a fourth position. When the guardrail 42 is in the third position, the guardrail 42 contacts the target object 38, and the support plate 36 is in the first position. When the guardrail 42 is in the fourth position, the guardrail 42 is separated from the target object 38, and the support plate 36 is in the second position. In this way, by separating the guardrail 42 from the target object 38, the guardrail 42 will not introduce errors when measuring the weight of the target object 38, so that the weighing device 30 can accurately measure the weight of the target object 38.
[0064] In some examples, as Figures 1 to 4 shown, the support plate 36 is configured to move along a first direction F to switch between the first position and the second position. The guardrail 42 is configured to move along a second direction S to switch between the third position and the fourth position. The first direction F and the second direction S are orthogonal to each other.
[0065] In some examples, as Figures 1 to 4 shown, the first direction F is the vertical direction, and the second direction S is the horizontal direction.
[0066] In some examples, as Figure 4 shown, a plurality of weighing holes 40 are arranged side by side in the second direction S.
[0067] In some examples, as Figure 2 shown, a plurality of teeth 62 are arranged side by side in the second direction S.
[0068] In some examples, as Figures 2 to 4As shown, the weighing device 30 further includes a driver 44 and a common component 46. The driver 44 is connected to the support plate 36 and the guardrail 42 via the common component 46 for driving the support plate 36 and the guardrail 42 to move. In this way, the movements of the support plate 36 and the guardrail 42 can be driven and completed uniformly by the movement of the common component 46, enabling the weighing device 30 to have a simple structure.
[0069] In some examples, as Figures 2 to 4 shown, the driver 44 is a motor. For example, the driver 44 can be a servo motor.
[0070] In some examples, as Figures 1 to 4 shown, the common component 46 is configured to be able to move in a first direction F under the drive of the driver 44.
[0071] In some examples, as Figures 1 to 4 shown, the common component 46 can be fixedly connected to the support plate 36 via a bracket 47, so that the support plate 36 can move along the first direction F together with the common component 46.
[0072] In some examples, as Figures 1 to 4 shown, the weighing device 30 further includes a connecting rod 48. The connecting rod 48 is rotatably connected to the guardrail 42 and the common component 46, and the common component 46 is connected to the guardrail 42 via the connecting rod 48.
[0073] In some examples, as Figures 1 to 4 shown, the rotation axes of the connecting rod 48 relative to the guardrail 42 and the common component 46 are parallel to a third direction T, and the third direction T is orthogonal to both the first direction F and the second direction S.
[0074] In some examples, as Figures 1 to 4 shown, the third direction T is a horizontal direction.
[0075] In some examples, a plurality of weighing seats 34 are arranged side by side in the third direction T, that is, the third direction T is the arrangement direction of the weighing seats 34.
[0076] In some examples, as Figures 1 to 4 shown, the weighing device 30 further includes a guiding track 50. The guiding track 50 is configured to guide the guardrail 42 to switch between a third position and a fourth position.
[0077] In some examples, as Figures 1 to 4 shown, the weighing device 30 further includes a sliding seat 64. The guiding track 50 is columnar, and the axial direction of the guiding track 50 is parallel to the second direction S. The sliding seat 64 is sleeved on the guiding track 50 and can slide along the second direction S under the guidance of the guiding track 50. The sliding seat 64 is fixedly connected to the guardrail 42, and the common component 46 is connected to the guardrail 42 via the connecting rod 48 and the sliding seat 64 in sequence.
[0078] In some examples, as Figures 1 to 4 shown, the guiding track 50 is stationary. For example, the guiding track 50 can be fixedly connected to a frame or a platen, etc.
[0079] In other words, as Figure 1 and Figure 4 shown, when the common element 46 moves from the upper position to the lower position along the first direction F, the support plate 36 moves from the upper first position to the lower second position along the first direction, the connecting rod 48 rotates and drives the slide 64 to move from the upper right position to the lower left position along the second square S, and the guardrail 42 moves from the upper right third position to the lower left fourth position along the second direction S. Conversely, when the common element 46 moves from the lower position to the upper position along the first direction F, the above-mentioned elements can move in the opposite manner.
[0080] In some examples, as Figure 3 and Figure 4 shown, the weighing device 30 further includes a roller 52 and a holder 54. The holder 54 is provided with a raceway 56, and the roller 52 is held in the raceway 56. The driver 44 is connected to the common element 46 via the roller 52 and the holder 54. The driver 44 is configured to be able to drive the roller 52 to swing, so that the roller 52 drives the holder 54 to move. In this way, by providing the roller 52 and the holder 54, the driver 44 can drive the common element 46 in a simple and smooth manner, further simplifying the structure of the weighing device 30.
[0081] In some examples, as Figure 3 and Figure 4 shown, the roller 52 swings around an axis parallel to the second direction S, and the holder 54 is configured to move along the first direction F under the drive of the roller 52.
[0082] In some examples, as Figure 3 and Figure 4 shown, the raceway 56 penetrates the holder 54 along the second direction S.
[0083] In some examples, as Figure 3 and Figure 4 shown, the raceway 56 has a length in the third direction T.
[0084] In some examples, as Figure 2 and Figure 4 shown, the weighing device 30 further includes a speed reducer 66 and a swing arm 68. The driver 44 is sequentially connected to the roller 52 via the speed reducer 66 and the swing arm 68. One end of the swing arm 66 is torsionally connected (a connection capable of transmitting torque) to the output end of the speed reducer 66, and the other end of the swing arm 66 is rotatably connected to the roller 52.
[0085] In some examples, such as Figure 3 and Figure 4 shown, the weighing device 30 further includes a bracket 70 and a setscrew 72. The setscrew 72 is supported on the bracket 70 and is screwed with the bracket 70. The two setscrews 72 are arranged opposite to each other, and the holding member 54 is restricted between the two setscrews 72. In this way, by screwing the setscrew 72, the two setscrews can approach and move away from each other, so that the moving range of the holding member 54 can be adjusted, making the weighing device 30 easy to debug.
[0086] In some examples, such as Figure 3 and Figure 4 shown, the axial direction of the setscrew 72 is parallel to the first direction F, and the two setscrews 72 are arranged opposite to each other in the first direction F.
[0087] In some examples, such as Figures 1 to 4 shown, the weighing device 30 further includes a transmission shaft 74 and a support 76. The holding member 54 is connected to the common element 46 via the transmission shaft 74. The support 76 is sleeved on the transmission shaft 74 and guides the transmission shaft 74 to move.
[0088] In some examples, such as Figures 1 to 4 shown, the axial direction of the transmission shaft 74 is parallel to the first direction F, and the support 76 guides the transmission shaft 74 to move along the first direction F.
[0089] In some examples, the transmission shaft 74 is slidably connected to the support 76 through a linear bearing. For example, the linear bearing can be an igus sleeve.
[0090] In some examples, the transmission shaft 74 is hermetically connected to the support 76. For example, a sealing ring and a dust-proof ring can be provided between the transmission shaft 74 and the support 76.
[0091] As Figure 1 shown, the embodiment of the present disclosure also provides a filling machine 58.
[0092] As Figure 1 and Figure 4 shown, the filling machine 58 includes a weighing device 30, a first conveying track, and a second conveying track 60. The first conveying track is used to guide the target object 38 to the support plate 36. The second conveying track 60 is used to receive the target object 38 from the support plate 36. When the support plate 36 is in the first position, the support plate 36 is docked with the first conveying track and the second conveying track 60. When the support plate 36 is in the second position, the support plate 36 is staggered from the first conveying track and the second conveying track 60.
[0093] In some examples, such as Figure 1 shown, the first conveying track and the second conveying track extend along the third direction T.
[0094] In some examples, when the support plate 36 is in the first position, the surfaces of the support plate 36, the first conveying track, and the second conveying track 60 that are used to contact the conveyed object 38 are substantially flush.
[0095] In some examples, when the support plate 36 is in the first position, the end of the support plate 36 facing the first conveying track engages with the first conveying track, and the end of the support plate 36 facing the second conveying track 60 engages with the second conveying track 60.
[0096] In some examples, as Figure 1 shown, the filling machine 58 further includes a first conveying tooth plate 78 and a second conveying tooth plate (not shown in the figure). The first conveying tooth plate 78 and the second conveying tooth plate are provided with tooth grooves 80 for receiving the target object 38. The first conveying tooth plate 78 is configured to be able to convey the target object 38 from the first conveying track to the support plate 36. The second conveying tooth plate is configured to be able to convey the target object 38 from the support plate 36 to the second conveying track 60.
[0097] In some examples, as Figure 1 shown, a plurality of tooth grooves 80 are arranged side by side in the third direction T.
[0098] The embodiment of the present disclosure also provides a weighing method for a filling machine 58, and the weighing method includes the following steps.
