Description

Technical Field

[0002] A labeling machine is an essential component of modern packaging processes, using adhesive as a medium to attach paper or metal foil labels to target containers. Before a labeling machine labels a medicine bottle, it is necessary to test the amount of medicine in the bottle to determine whether it meets the standard range.

[0003] In the prior art, medicine bottles are moved horizontally through a belt conveyor mechanism, and the amount of medicine is detected by an infrared signal sensor; when it is determined that the medicine bottles passing through the detection area do not meet the standard range, a rejection cylinder is used to push the medicine bottles out of the belt conveyor mechanism so that the medicine bottles can be recovered and facilitate subsequent rehydration operations.

[0004] The inventors found that the existing infrared signal sensor can only determine whether there is liquid medicine in the bottle, but cannot determine the amount of liquid medicine, and thus cannot classify bottles with different amounts of medicine, making it difficult to directly carry out the subsequent rehydration process and reducing the execution efficiency of the labeling process.

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] Please also refer to Figures 1 to 11 The medicine bottle sorting and recycling mechanism for a labeling machine provided in this application is now described. The medicine bottle sorting and recycling mechanism for a labeling machine provided in this application includes a rejecting component 1, a base 2, a weighing component 4, a pushing component 5, a plurality of recycling buckets 6, and a controller 10.

[0052] In this embodiment, the labeling machine includes a belt conveyor mechanism 100 for horizontally moving medicine bottles. For ease of description, the belt conveyor mechanism 100's conveying direction is defined as the forward-backward direction. Furthermore, it should be noted that the left and right sides of the conveying surface of the belt conveyor mechanism 100 are unobstructed, allowing for the passage of medicine bottles and other components.

[0053] The rejecting member 1 is disposed on one side of the belt conveying mechanism 100 in the left-right direction, and is used to drive the medicine bottle to move along the left-right direction to separate from the belt conveying mechanism 100.

[0054] It should be noted that, in actual use, the start timing of the rejection component 1 can be achieved in the following two ways: one is through manual observation and start-up, and the other is achieved with the help of the controller 10 and the detection module equipped on the belt transmission mechanism 100. Specifically, when the detection module detects a medicine bottle with insufficient liquid, the controller 10 controls the rejection component 1 to start.

[0055] The base 2 is disposed on the side of the belt conveyor 100 facing away from the rejection member 1 and is typically fixed to a support surface (usually the ground) coplanar with the belt conveyor 100. A turntable 3 is rotatably connected to the base 2 on its upper side in the vertical direction. The upper side of the turntable 3 is coplanar with the conveying surface of the belt conveyor 100 and is used to support medicine bottles that have been removed from the belt conveyor 100, specifically medicine bottles that have been pushed off the belt conveyor 100 by the rejection member 1. In this embodiment, a rotation drive member 31 is rotatably connected to the turntable 3, and the turntable 3 has a through hole 32 extending therethrough in the vertical direction. The position of the through hole 32 can be adjusted by rotating the rotation drive member 31, so that the medicine bottles that have landed on the turntable 3 can be arranged coaxially with the through hole 32.

[0056] It should be noted that, according to the size of the medicine bottle, the pushing distance of the rejection member 1 can be preset to ensure that the medicine bottle can be accurately moved to a position coaxially arranged with the through hole 32.

[0057] The weighing components 4 are arranged in parallel on the outside of the base 2, and are usually fixed on the ground coplanar with the bottom surface of the base 2, and are used to connect with the medicine bottle from bottom to top through the through hole 32 to detect the weight of the medicine bottle; that is, when this weighing component 4 is started, its weighing end moves upward to pass through the through hole 32 and connect with the bottom surface of the medicine bottle, thereby realizing the weighing of the medicine bottle, and subsequently judging the classification of the liquid amount based on this weight value.

[0058] The pushing member 5 is arranged at the center of the turntable 3, and is used to push the medicine bottle toward the through hole 32 to make the medicine bottle detach from the turntable 3; it should be pointed out that this pushing member 5 can rotate synchronously with the rotation of the turntable 3 to achieve the pushing of the medicine bottle in multiple detachment positions.

[0059] Multiple recovery buckets 6 are arranged at intervals along the circumference of the turntable 3 on the outside of the base 2, and are all located on the lower side of the turntable 3 to receive medicine bottles that have detached from the turntable 3, specifically medicine bottles that have been pushed out of the turntable 3 by the pushing member 5.

[0060] The controller 10 is electrically connected to the control module of the rejection member 1, the control module and signal output module of the weighing member 4, the control module of the pushing member 5, and the control module of the rotation drive member 31; in this embodiment, the main body of the controller 10 is set on the pushing member 5 to ensure immediate response of the signal.

[0061] The controller 10 can preset multiple groups of numerical ranges and compare the numerical values ​​output by the weighing component 4, so that the push component 5 can be directed toward one of the recycling buckets 6 by rotating the driving component 31 to drive the turntable 3 to rotate, so as to be suitable for pushing the medicine bottle into the recycling bucket 6; specifically, each group of numerical ranges corresponds to an angle value. When the numerical value output by the weighing component 4 falls into one of the numerical values, the rotating driving component 31 drives the turntable 3 to rotate the corresponding angle, so that the pushing component 5 is directed toward the corresponding recycling bucket 6 to realize the medicine bottle recycling step.

[0062] It should be noted that when the rejection member 1 is started, the controller 10 receives a signal and controls the rotation drive member 31 to start, so that the turntable 3 is reset to a position where the through hole 32 and the rejection member 1 are parallel in the left-right direction; then, the controller 10 controls the rotation drive member 31 to start, so that the turntable 3 is moved to a position where the through hole 32 and the weighing member 4 are arranged in the up-down direction; then, the controller 10 controls the weighing member 4 to start, so that the weighing member 4 moves upward to pass through this through hole 32, thereby completing the weighing and performing the subsequent recycling steps.

[0063] In the embodiment of the present application, the rejection component 1 can push the medicine bottle with a dosage that does not meet the range with its own transmission mechanism 100 onto the turntable 3, and make the medicine bottle and the through hole 32 overlap; then, by rotating the drive component 31 to drive the turntable 3 to rotate, the medicine bottle can be moved to the weighing component 4; at the same time, the weighing component 4 moves upward to pass through the through hole 32 and connect with the medicine bottle, so that the medicine bottle can be weighed, and this value is output to the controller 10 for comparison, so that the controller 10 outputs control signals to the rotation drive component 31 and the pushing component 5 in turn, so that the turntable 3 rotates until the medicine bottle moves to the top of one of the recovery buckets 6, and the pushing component 5 pushes the medicine to leave the turntable 3 and fall into this recovery bucket 6.

[0064] Compared with the prior art, the medicine bottle classification and recovery mechanism for the labeling machine provided in this embodiment can remove medicine bottles with medicine quantities that do not meet the standard range through the self-contained transmission mechanism 100, and classify and recover the medicine bottles to ensure that subsequent processes proceed smoothly, thereby ensuring the overall efficiency of the labeling process.

[0065] In some embodiments, as Figure 1 and Figure 2 As shown, the rejecting member 1 includes a first linear cylinder 11 and a first push plate 12 .

[0066] The first linear cylinder 11 is fixedly mounted on one side of the belt transmission mechanism 100 in the left-right direction via a first bracket 111 , with its power output axis parallel to the left-right direction, and its control module is electrically connected to the controller 10 .

[0067] In the control system of this mechanism, since the control module of the first linear cylinder 11 is electrically connected to the controller 10 , the start timing and duration of the first linear cylinder 11 can be controlled by the controller 10 .

[0068] It should be noted that, the design here can also be as follows: when the first linear cylinder 11 is started, the first linear cylinder 11 sends a signal to the controller 10 to ensure that subsequent operation steps are performed in sequence.

[0069] The first push plate 12 is fixedly connected to the power output end of the first linear cylinder 11 , and its lower side surface is coplanar with the conveying surface of the belt transmission mechanism 100 , and is used to abut against the medicine bottle and push the medicine bottle to detach from the belt transmission mechanism 100 .

[0070] The first push plate 12 has anti-slip portions 121 at both ends in the front-to-back direction; in the direction of the first push plate 12 toward the belt transmission mechanism 100, each anti-slip portion 121 is tilted away from the first push plate 12 to adapt to medicine bottles of different sizes and prevent the medicine bottles from tilting and shifting in the front-to-back direction during the left and right pushing process.

[0071] In some embodiments, as Figures 4 to 6 As shown, the weighing component 4 includes a fixing frame 41 and a pressure sensor 42 .

[0072] The fixing frame 41 is fixedly mounted on the outside of the base 2 and has an eccentric wheel 411 rotatably connected thereto. It should be noted that the eccentric wheel 411 has a circular vertical cross-section, and the connecting axis between the eccentric wheel 411 and the fixing frame 41 is parallel to (and not coincident with) the central axis of the eccentric wheel 411. Furthermore, the fixing frame 41 also has a first rotating motor 412 in transmission connection with the eccentric wheel 411.

[0073] The pressure sensor 42 is slidably connected to the fixed frame 41 along the up and down directions, and its lower end is connected to the outer peripheral wall of the eccentric wheel 411, and its signal output module is electrically connected to the controller 10; when the first rotating motor 412 drives the eccentric wheel 411 to rotate, the pressure sensor 42 can move along the up and down directions driven by the eccentric wheel 411, so as to be suitable for passing through the through hole 32 from bottom to top and connecting with the medicine bottle.

[0074] In the control system of this mechanism, since the control module of the first rotary motor 412 is electrically connected to the controller 10, the controller 10 can control the activation timing and duration of the first rotary motor 412, thereby adjusting the timing and length of insertion of the pressure sensor 42 into the through-hole 32. Since the signal output module of the pressure sensor 42 is electrically connected to the controller 10, the controller 10 can receive the signal value output by the pressure sensor 42, compare it with a preset value range, and generate control signals for other components.

[0075] In some embodiments, as Figure 1 and Figure 11 As shown, there are multiple through holes 32, and the multiple through holes 32 are arranged at intervals along the circumference of the turntable 3; the purpose of this design is to provide the turntable 3 with multiple support positions for docking medicine bottles, so that the use of the turntable 3 is more convenient.

[0076] The upper side surface of the turntable 3 has a plurality of sinking grooves 33 corresponding to and communicating with the plurality of through holes 32 , and a tray 34 is inserted and slidably connected to each sinking groove 33 along the up-down direction.

[0077] When the lower side of the tray 34 is connected to the bottom of the sinking trough 33, the upper side of the tray 34 is coplanar with the upper side of the turntable 3, so as to be suitable for supporting the medicine bottle that is detached from the belt transmission mechanism 100; and the weighing component 4 is connected to the medicine bottle through the tray 34.

[0078] In some embodiments, as Figure 11 As shown, the multiple sinking grooves 33 are of different sizes, and the outer peripheral wall of each tray 34 is connected to the inner peripheral wall of the corresponding sinking groove 33 to adapt to medicine bottles of different sizes.

[0079] In some embodiments, as Figure 1 、 Figure 7 and Figure 9 As shown, the pushing member 5 includes a second linear cylinder 51 and a second pushing plate 52 .

[0080] The second linear cylinder 51 is positioned at the center of the turntable 3 via a positioning platform 7. Its power output axis is perpendicular to the vertical direction, and its control module is electrically connected to the controller 10. The positioning platform 7 is connected to the turntable 3 for vertical rotation, and a locking structure 9 is provided between the positioning platform 7 and the turntable 3. This locking structure 9 connects the positioning platform 7 and the turntable 3, thereby locking the orientation of the second linear cylinder 51.

[0081] The reason why the second linear cylinder 51 is designed to be rotatable relative to the turntable 3 is to cooperate with the embodiment of "multiple through holes 32" mentioned in the above content, so that this component can be adapted to any through hole 32.

[0082] The second push plate 52 is fixedly connected to the power output end of the second linear cylinder 51, and is suitable for moving toward any through hole 32 to abut the side of the medicine bottle toward the central axis of the turntable 3, and can push the medicine bottle to detach from the turntable 3, so that it falls into one of the recovery buckets 6.

[0083] In some embodiments, as Figure 10 As shown, the positioning platform 7 has a protrusion 71 extending outward in the horizontal direction, and the aforementioned locking structure 9 is arranged between the protrusion 71 and the turntable 3.

[0084] In this embodiment, the locking structure 9 includes a positioning hole 91 , a plurality of alignment slots 92 and a locking rod 93 .

[0085] The positioning hole 91 is formed on the raised portion 71 and passes through the raised portion 71 in the vertical direction.

[0086] A plurality of alignment grooves 92 are provided on the upper side surface of the turntable 3 and are spaced apart along the circumference of the turntable 3 . As the turntable 3 rotates, each alignment groove 92 is adapted to be coaxially connected to the positioning hole 91 .

[0087] The locking rod 93 is adapted to be inserted into the interconnected positioning hole 91 and the alignment groove 92 from top to bottom to limit the movement of the positioning platform 7 relative to the turntable 3 , thereby locking the position between the turntable 3 and the positioning platform 7 .

[0088] In some embodiments, as Figure 8 As shown, the upper end of the base 2 has a receiving groove 21; the rotation driving member 31 is a second rotating motor fixedly arranged in the receiving groove 21, and the power output axis of this second rotating motor is parallel to the up and down direction, and the power output end of the second rotating motor is coaxially connected to the turntable 3; that is, the base 2 is rotationally connected to the turntable 3 through this second rotating motor.

[0089] Furthermore, the control module of the second rotating motor is electrically connected to the controller 10 .

[0090] In some embodiments, as Figure 1 and Figure 3 As shown, the belt transmission mechanism 100 has a second bracket 8 on the side facing away from the rejecting component 1, and the upper side of the second bracket 8 is connected to the lower side of the turntable 3 to support the turntable 3 and improve the structural strength of the mechanism.

[0091] In some embodiments, as Figure 1 and Figure 3 As shown, the upper side of the second bracket 8 has a filling piece 81 ; in this embodiment, the filling piece 81 is divided into two parts, and is respectively located at the front and rear sides of the turntable 3 .

[0092] Among them, each filling piece 81 is connected to the outer peripheral wall of the turntable 3, and the upper side surface of the filling piece 81 is coplanar with the upper side surface of the turntable 3, so as to be suitable for supporting the medicine bottles moving toward the turntable 3 by the self-contained transmission mechanism 100 to prevent the medicine bottles from falling.

[0093] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
