Description
TECHNICAL FIELD
[0001] The utility model relates to the field of filling, particularly to a weighing and conveying integrated mechanism based on bottle body filling and a filling machine. BACKGROUND
[0002] In the field of pharmaceutical filling, the weighing station is usually the key part of the equipment for accurately controlling the filling dose of the medicine.
[0003] In the prior art, the weighing station of a penicillin bottle mainly consists of a bracket lifting mechanism and a weighing installation assembly to form a precise operation system. The specific filling and weighing process mainly includes the following steps:
[0004] The conveying mechanism accurately pushes the penicillin bottle to the filling station according to the predetermined program, and makes the penicillin bottle fall steadily on the bracket;
[0005] Under the instruction of the control terminal, the bracket lifting mechanism drives the bracket to move vertically downward first, and then moves backward along a specific trajectory by means of a series of mechanical linkage mechanisms such as connecting rods, so that the penicillin bottle can be separated from the bracket support and fall onto the weighing head to prepare for weighing detection.
[0006] In the above process, due to the backward movement of the bracket, the guardrail rigidly connected and fixedly installed on the bracket also moves backward synchronously, so that the penicillin bottle is completely separated from the surrounding restraint of the guardrail, ensuring that the weighing head can accurately obtain the weight data of the penicillin bottle and its internal material, and ensuring the accuracy of filling and weighing.
[0007] However, it is found through actual application that the above operation process has certain defects: in the above process, the bracket lifting and the waiting for stable reading of the weighing head need to be performed in sequence, and there is an indispensable time interval between the two actions to ensure the accuracy of the action and the stability of the equipment, which inevitably greatly prolongs the beat time of the entire filling and weighing link, thereby restricting the overall running speed of the equipment and making it difficult to meet the efficient production demand.

[0056] The integrated weighing and conveying mechanism and filling machine based on bottle filling of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.
[0057] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0058] Example 1
[0059] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes an integrated weighing and conveying mechanism based on bottle filling, including a guardrail track 1, a star wheel 2, a weighing track 3, and a weighing sensor 4.
[0060] The star wheel 2 is rotatably mounted on one side of the guardrail track 1, and its rotation center point coincides with the center of the arc trajectory of the guardrail track 1, which is used to drive the bottle to move along the guardrail track 1.
[0061] It should be noted that the star wheel 2 is connected to the drive component (not shown in the figure) to drive the star wheel 2 to rotate and complete the conveying of the bottle.
[0062] Furthermore, the guardrail track 1 has a notch 5 in the middle for installing the weighing track 3, so that the weighing track 3 and the guardrail track 1 are separate structures to form a track for moving the bottle, but the two do not interfere with each other, so as to avoid errors in the weighing structure caused by the interference of the guardrail track 1 during weighing, and ensure the accuracy of weighing.
[0063] Specifically, the weighing track 3 is located at the notch 5, and a gap is reserved between it and the guardrail track 1, and the weighing sensor 4 is connected to the bottom.
[0064] In this embodiment, the weighing track 3 has two arc-shaped transition sections 6 and a raised section 7 that match the guardrail track 1.
[0065] The two arc-shaped transition sections 6 are respectively used to receive the bottle conveyed by the guardrail track 1 and to output the bottle to the guardrail track 1, so that the bottle can smoothly transition from the guardrail track 1 to the weighing track 3.
[0066] The convex section 7 is located between two arc transition sections 6 and is convex outward away from the rotation center point of the star wheel 2.
[0067] It is particularly noted that the convex section 7 and the arc transition section 6 are in communication with each other, that is, the arc track of the convex section 7 deviates from the guardrail track 1, but under the pushing action of the star wheel 2, the bottle body can also be pushed by the arc transition section 6 to the convex section 7, and since the convex section 7 is convex outward away from the rotation center point of the star wheel 2, when the bottle body is located in the convex section 7, the bottle body can be separated from the pushing notch of the star wheel 2 (that is, when the bottle body is transported from the arc transition section 6 to the convex section 7 under the rotation driving force of the star wheel 2, the bottle body is just completely separated from the star wheel 2), so at this time, the bottle body and the star wheel 2 and the weighing track 3 and the guardrail track 1 are all in a non-contact state, thereby effectively ensuring the measurement accuracy of the weight of the bottle body to ensure the accuracy of subsequent filling.
[0068] The device sets the guardrail track 1 with a notch 5 at the middle position and sets the weighing track 3 at the notch 5 to form a track path, so that under the action of the star wheel 2, the bottle body can be moved from the guardrail track 1 to the weighing track 3, and since the weighing track 3 has the arc transition section 6 and the convex section 7 and the bottle body can be completely separated from the star wheel 2 when located in the convex section 7. Therefore, during operation, only the star wheel 2 needs to be rotated by a specific angle to control the bottle body to be located in the convex section 7, which can ensure that the weighing is not disturbed by external factors and ensure the accuracy of the weighing, and in this process, no other steps need to be performed, that is, only the rotation of the star wheel 2 is needed, compared with the way of using a linkage to control the weighing accuracy in the prior art. The device achieves the purpose of shortening the tact time required for weighing under the premise of ensuring the weighing accuracy to improve the production rate.
[0069] As shown in Figure 4 and Figure 5 In this embodiment, a specific weighing track 3 is also proposed to better form the convex section 7, thereby facilitating the quick separation between the bottle body and the star wheel 2 and ensuring the accuracy of subsequent weighing.
[0070] Specifically, the weighing track 3 includes a track plate 31, a first side baffle 32, and a second side baffle 33.
[0071] The first side baffle 32, the second side baffle 33, and the track plate 31 surround a channel for the movement of the bottle body, and the channel has the arc transition section 6 and the convex section 7.
[0072] It should be noted that the middle part of the first side baffle 32 is convex in the direction away from the rotation center point of the star wheel 2, and the middle part of the second side baffle 33 is concave in the direction away from the rotation center point of the star wheel 2, so as to form the convex section 7, and further make the convex section 7 and the arc-shaped transition section 6 not only in communication, but also make the bottle body separated from the pushing socket of the star wheel 2 when located in the convex section 7, so as to ensure that the star wheel 2 does not form extrusion or other force on the bottle body, and affect the weighing effect of the weighing sensor 4 on the bottle body.
[0073] It should be further particularly noted that, in order to ensure that the star wheel 2 can realize the rotating conveying function on the bottle body, the first side baffle 32 and the second side baffle 33 are further limited, specifically, the first side baffle 32 is located below the star wheel 2, and the second side baffle 33 is exposed outside the star wheel 2, so that the bottle body can be located at the pushing socket of the star wheel 2, to ensure the smooth pushing of the star wheel 2, and ensure that the existence of the weighing track 3 does not interfere with the operation of the star wheel 2.
[0074] It should be particularly noted that, when the bottle body is located in the convex section 7, the pushing socket of the star wheel 2 is sleeved outside the bottle body, that is, the inner wall of the U-shaped cavity formed by the pushing socket is completely separated from the bottle body, and when the weighing operation is completed and the star wheel 2 rotates, the inner wall of the pushing socket is in contact with the bottle body, so as to carry the bottle body to the next station (i.e. the guardrail track 1).
[0075] Please continue to refer to Figure 3 In further embodiments, a specific guardrail track 1 is also proposed to improve the conveying effect of the bottle body. Specifically, the guardrail track 1 comprises a guardrail plate 11, a star wheel track 12 and a bottle bottom track 13.
[0076] Among them, the star wheel track 12 and the bottle bottom track 13 are fixedly connected with the guardrail plate 11.
[0077] And, the gap 5 is formed between the bottle bottom track 13 and the star wheel track 12, which is used for installing the weighing track 3.
[0078] It should be particularly noted that the side of the second side baffle 33 in contact with the bottle body is located between the guardrail plate 11 and the star wheel 2, so as to ensure that the bottle body located between the second side baffle 33 and the first side baffle 32 does not contact the guardrail plate 11, so as to further improve the weighing precision.
[0079] As Figure 5 shown, in order to improve the stability of the bottle body in the transmission between the bottle bottom track 13 and the weighing track 3 and between the weighing track 3 and the star wheel track 12, the guardrail track 1 and the track plate 31 are further limited.
[0080] Specifically, both sides of the bottle bottom track 13 and one end of the star wheel track 12 are provided with grooves 8, and both ends of the track plate 31 have flanges 9 extending into the grooves 8, so as to connect the weighing track 3, the star wheel track 12 and the bottle bottom track 13 in series, that is, by providing the flanges 9 and the grooves 8, the flanges 9 are used as a connecting excess part, thereby effectively improving the stability of the bottle body during transmission between the star wheel track 12 and the weighing track 3 and between the weighing track 3 and the bottle bottom track 13.
[0081] It should be noted that the flange 9 and the groove 8 are always in a non-contact state, which ensures that the measurement accuracy is not affected.
[0082] As shown in Figure 4 In order to improve the filling effect, the notches 5, the weighing track 3 and the weighing sensor 4 are provided with two in this embodiment, and the transmission direction of the bottle body is as shown by the Va direction in Figure 4 For convenience of description, the two weighing sensors 4 are named as the front weighing sensor 4 and the rear weighing sensor 4 along the Va direction.
[0083] It should be noted that the front weighing sensor 4 is used for measuring the weight of the bottle body itself (i.e. empty bottle weight measurement), and the rear weighing sensor 4 is used for measuring the bottle body after filling, so as to ensure that there is no impurity in the bottle body before filling and to ensure the accuracy of the bottle body after filling.
[0084] In other embodiments, a supplementary filling mechanism is further provided at the next node of the rear weighing sensor 4 along the Va direction, and when the weight measured by the rear weighing sensor 4 is lower than the preset parameter, the supplementary filling mechanism can be used to complete the re-filling, so as to improve the overall filling effect.
[0085] As shown in Figure 6 and Figure 7 The connection mode of the weighing track 3 and the weighing sensor 4 is limited to detachable connection, so that the operator can quickly adjust the weighing track 3 according to the requirements (such as the specifications of the bottle body).
[0086] Specifically, the weighing sensor 4 is fixedly installed with a weighing head fixing plate 41, and the lower surface of the weighing track 3 is fixedly installed with a connecting block 10, and the connecting block 10 is inserted into the weighing head fixing plate 41 in an interference fit, so as to achieve the purpose of conveniently replacing the weighing track 3.
[0087] Embodiment two
[0088] The embodiment is based on the filling machine of embodiment one, and makes the filling machine to be able to reduce the tact time required by the weighing process on the premise of ensuring the precision when the bottle body is completed to be filled to carry out the weighing operation, so as to achieve the purpose of ensuring the filling precision and improving the production rate.
[0089] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
