[0034] The following combination Figures 1 to 4 A transfer device for an aluminum-plastic packaging machine according to an embodiment of the present invention is described.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, the transfer device for the aluminum-plastic packaging machine provided by the embodiment of the present invention includes: a base 1, a driving mechanism 2, a rotating mechanism 4, a guiding mechanism 5 and an adsorption mechanism 3; the driving mechanism 2 is connected to the base 1, the base 1 includes a turntable 11 and a central axis 12 and a rotating axis 13 arranged on opposite sides of the turntable 11, the rotating mechanism 4 is rotatably connected to the turntable 11, and the guiding mechanism 5 is slidably connected to the central axis 12; the adsorption mechanism 3 is arranged on one side of the turntable 11, the adsorption mechanism 3 includes a support rod 31 and an adsorption member 32 connected to the support rod 31, and the adsorption member 32 is used to adsorb materials; the rotating mechanism 4 and the guiding mechanism 5 are both connected to the support rod 31; the driving mechanism 2 is used to drive the base 1 to rotate, and the rotating mechanism 4 and the guiding mechanism 5 are used to drive the support rod 31 to rotate, and enable the support rod 31 to reciprocate relative to the central axis 12.

[0036] Specifically, the aluminum-plastic packaging machine includes components such as an unwinding mechanism, a heating mechanism, a forming mechanism, and a punching mechanism. The punching mechanism is used to cut the formed whole medicine sheet into multiple small pieces. A transfer device is located behind the punching mechanism and is used to transfer the cut medicine sheets to the next workstation for corresponding operations. For example, after the transfer device picks up the medicine sheets, it transfers unqualified medicine sheets to a collection bin and transfers qualified medicine sheets to a conveying mechanism. The conveying mechanism further transports the qualified medicine sheets to the packaging station for packaging.

[0037] The transfer device of the present invention includes a base 1, which includes a turntable 11. A central axis 12 and a rotating axis 13 are provided at the center of the turntable 11. The central axis 12 and the rotating axis 13 are located on opposite sides of the turntable 11. It is defined that the central axis 12 is located on a first side of the turntable 11 and the rotating axis 13 is located on a second side of the turntable 11. The central axis 12 and the rotating axis 13 are both fixedly connected to the turntable 11, and the rotating axis 13 and the central axis 12 are arranged coaxially. The central axis 12 is connected to the guide mechanism 5, and the rotating axis 13 is connected to the drive mechanism 2. The drive mechanism 2 drives the rotating axis 13 to rotate, thereby driving the turntable 11 and the central axis 12 to rotate synchronously.

[0038] The adsorption mechanism 3 includes a support rod 31 and an adsorption member 32 mounted on the support rod 31. In the present invention, the material is described by taking the medicine plate as an example. The adsorption end of the adsorption member 32 can adsorb the medicine plate and release the medicine plate at the same time. The rotating mechanism 4 is rotatably connected to the turntable 11, and the rotating mechanism 4 can rotate synchronously with the turntable 11, and the rotating mechanism 4 can rotate on its own. The support rod 31 is connected to the rotating mechanism 4, and the rotating mechanism 4 can drive the support rod 31 to rotate with the turntable 11; the rotating mechanism 4 is rotatably connected to the turntable 11, and the guide mechanism 5 is slidably connected to the central axis 12. The rotating mechanism 4 and the guide mechanism 5 are both connected to the support rod 31. Through the rotation of the rotating mechanism 4 and the sliding of the guide mechanism 5, the support rod 31 can reciprocate relative to the central axis 12.

[0039] The turntable 11 is arranged around its circumference with a first, second, and third station. For example, the second station forms a 180-degree angle with the first, and the third station forms a 90-degree angle with the second. The first station houses the cut tablets; the second station houses a collection bin for rejecting tablets; and the third station houses a conveyor mechanism, including a conveyor belt, for transporting qualified tablets. The adsorption mechanism 3 can rotate to the first, second, and third stations in sequence.

[0040] The working process of the transfer device is described in detail below. The driving mechanism 2 drives the turntable 11 to rotate. In the process of the turntable 11 driving the rotating mechanism 4 and the guide mechanism 5 to rotate toward the first workstation, the rotating mechanism 4 and the guide mechanism 5 drive the support rod 31 to move in the direction away from the center axis 12. As a result, the adsorption mechanism 3 rotates toward the first workstation as the turntable 11 rotates, and at the same time moves in the direction away from the center axis 12 until it moves to the first workstation. The adsorption end of the adsorption part 32 adsorbs the medicine plate at the first workstation under negative pressure conditions, and then the rotating mechanism 4 and the guide mechanism 5 drive the support rod 31 to move in the direction close to the center axis 12, completing the absorption operation of the medicine plate. The turntable 11 then drives the rotating mechanism 4 and the guide mechanism 5 to continue rotating toward the second station. Simultaneously, the rotating mechanism 4 and the guide mechanism 5 drive the support rod 31 in a direction away from the central axis 12 until it reaches the second station. The suction end of the adsorbent 32 releases the unqualified tablets under positive pressure, and the unqualified tablets fall into the collection bin under gravity. The rotating mechanism 4 and the guide mechanism 5 then drive the support rod 31 toward the central axis 12. The turntable 11 then drives the rotating mechanism 4 and the guide mechanism 5 to continue rotating toward the third station. Simultaneously, the rotating mechanism 4 and the guide mechanism 5 drive the support rod 31 in a direction away from the central axis 12 until it reaches the third station. The suction end of the adsorbent 32 releases the qualified tablets under positive pressure, and the qualified tablets fall onto the conveyor belt and are further transported to the packaging station along the conveyor belt. After the suction end of the adsorbent 32 releases the qualified tablets, the rotating mechanism 4 and the guide mechanism 5 drive the support rod 31 toward the central axis 12. It can be understood that the support rod 31 and the adsorption member 32 installed on the support rod 31 move synchronously.

[0041] Thus, the adsorption mechanism 3 sequentially completes the adsorption of the tablets, the transfer of unqualified tablets, and the transfer of qualified tablets within one rotation of the turntable 11. The adsorption mechanism 3 reciprocates relative to the central axis 12 as the turntable 11 rotates, shortening the duration of each operation and thereby improving the transfer efficiency of the tablets.

[0042] In an embodiment of the present invention, the driving mechanism 2 drives the base 1 to rotate, and the rotating mechanism 4 and the guiding mechanism 5 rotate with the base 1, driving the adsorption mechanism 3 to rotate with the turntable 11. The rotating mechanism 4 and the guiding mechanism 5 are both connected to the support rod 31. The rotating mechanism 4 and the guiding mechanism 5 can drive the adsorption mechanism 3 to reciprocate relative to the center axis 12. Therefore, during the process of the adsorption mechanism 3 rotating with the turntable 11, it can also reciprocate relative to the center axis 12, shortening the working time of absorbing or placing materials, which is beneficial to improving the transfer efficiency.

[0043] like Figure 2As shown, in an optional embodiment, the driving mechanism 2 includes a synchronous pulley, a synchronous belt and a motor; the synchronous pulley is connected to the rotating shaft 13, and the synchronous pulley is connected to the motor through the synchronous belt.

[0044] Specifically, the drive mechanism 2 is disposed on the second side of the turntable 11 and includes a synchronous pulley, a synchronous belt, and a motor. A support frame is provided on the second side of the turntable 11, which can be connected to the frame of the aluminum-plastic packaging machine. One end of a rotating shaft 13 is connected to the turntable 11, and the other end of the rotating shaft 13 is rotatably connected to the support frame. The synchronous pulley is coaxially disposed with the rotating shaft 13, is sleeved around the rotating shaft 13, and is connected to the rotating shaft 13 via a key. The number of teeth on the synchronous pulley is not specifically limited; for example, the number of teeth on the synchronous pulley can be 87.

[0045] The motor can also be installed on the frame of the aluminum-plastic packaging machine. A driving wheel is installed on the rotating shaft of the motor, and a synchronous belt is sleeved on the driving wheel and the synchronous pulley. The motor rotates, driving the synchronous pulley to rotate, and then driving the rotating shaft 13 to rotate. The driving mechanism 2 has a compact structure and rotates smoothly, which is conducive to the compactness of the overall structure of the transfer device.

[0046] like Figure 1 and Figure 3 As shown, in an optional embodiment, the rotating mechanism 4 includes a rotating shaft 41, a driving member and a first connecting member 42; the rotating shaft 41 is rotatably connected to the turntable 11, one end of the first connecting member 42 is connected to the rotating shaft 41, and the other end of the first connecting member 42 is hinged to the support rod 31; the driving member is used to drive the rotating shaft 41 to rotate, and the rotating shaft 41 drives the support rod 31 to move through the first connecting member 42.

[0047] Specifically, the rotating shaft 41 is disposed circumferentially around the central axis 12, with its axis parallel to the axis of the central axis 12. The rotating shaft 41 is rotationally connected to the turntable 11. For example, a first bearing matching the rotating shaft 41 is mounted on the turntable 11, and the rotating shaft 41 is inserted through the first bearing, with a clearance fit or transition fit therewith. A small motor can be disposed on the second side of the turntable 11, in transmission connection with the rotating shaft 41, and driven by the small motor to rotate the rotating shaft 41 about its axis. Alternatively, the rotating shaft 41 can be driven by a planetary gear assembly.

[0048] One end of the rotating shaft 41 located on the first side of the rotating disk 11 is connected to the first connecting member 42. One end of the first connecting member 42 can be connected to the rotating shaft 41 by welding or screwing, and the other end of the first connecting member 42 is hingedly connected to the support rod 31. For example, a second bearing is provided at the other end of the first connecting member 42, and the axis of the second bearing is parallel to the axis of the rotating shaft 41. The end of the support rod 31 closest to the rotating disk 11 is inserted into the second bearing, thereby achieving the hinged connection between the first connecting member 42 and the support rod 31.

[0049] In an embodiment of the present invention, the rotating shaft 41 is rotatably connected to the turntable 11, and the rotating shaft 41 is hinged to the support rod 31 through the first connecting member 42. The driving member drives the rotating shaft 41 to rotate around its axis, and the rotating shaft 41 drives the support rod 31 to move through the first connecting member 42, so that the support rod 31 can move in a direction close to or away from the central axis 12. The structure is simple and easy to implement.

[0050] like Figure 2 and Figure 3 As shown, in an optional embodiment, the driving member includes a first gear 43 and a second gear 44; the first gear 43 is provided at one end of the rotating shaft 41 away from the first connecting member 42, the first gear 43 is meshedly connected to the second gear 44, and the second gear 44 is rotatably connected to the turntable 11.

[0051] Specifically, the driving member includes a first gear 43 and a second gear 44, which are internally meshed and connected. The number of teeth of the first gear 43 and the second gear 44 is set according to actual needs. For example, the number of teeth of the first gear 43 is 90, and the number of teeth of the second gear 44 is 360. The second gear 44 is rotatably connected to the turntable 11 via a third bearing.

[0052] The end of the rotating shaft 41 facing away from the first connecting member 42 is connected to the first gear 43. The rotating shaft 41 and the first gear 43 can be integrally formed, or the rotating shaft 41 can be detachably connected to the first gear 43 via a key. As the turntable 11 rotates, the first gear 43 and the second gear 44 rotate with the turntable 11. Under the meshing action of the first gear 43 and the second gear 44, the first gear 43 simultaneously rotates, thereby driving the rotating shaft 41 to rotate about its axis. The rotating shaft 41 further drives the support rod 31 through the first connecting member 42 to move toward or away from the central axis 12.

[0053] In an embodiment of the present invention, the first gear 43 is arranged on the second side of the turntable 11, and the first gear 43 is connected to the end of the rotating shaft 41 away from the first connecting member 42. The first gear 43 is internally meshed with the second gear 44, and the second gear 44 is rotatably connected to the turntable 11. In the process of the first gear 43 and the second gear 44 rotating with the turntable 11, under the meshing action of the first gear 43 and the second gear 44, the first gear 43 rotates and drives the rotating shaft 41 to rotate. As a result, the rotating shaft 41 rotates at the same time as the turntable 11 rotates, so that the first connecting member 42 can drive the support rod 31 to reciprocate in the direction close to or away from the center axis 12. The overall structure is compact and the movement is smooth.

[0054] like Figure 3As shown, in an optional embodiment, the first connecting member 42 includes a first connecting rod 421 and a first fastener; one end of the first connecting rod 421 is provided with a first through hole and a second through hole, the rotating shaft 41 is passed through the first through hole, and the first fastener is passed through the second through hole, for realizing a detachable connection between the first connecting rod 421 and the rotating shaft 41.

[0055] Specifically, the first connecting member 42 is used to connect the rotating shaft 41 and the support rod 31. The first connecting member 42 includes a first connecting rod 421 and a first fastener. For example, the first connecting rod 421 may have a threaded hole extending therethrough, and the end of the rotating shaft 41 may be provided with external threads, so that the first connecting rod 421 is threadedly connected to the rotating shaft 41. Alternatively, the first connecting rod 421 may have a first through hole and a second through hole extending therethrough, the axes of the first through hole and the second through hole being perpendicular, the inner diameter of the first through hole matching the diameter of the rotating shaft 41, and a first installation gap formed at the end of the first connecting rod 421, the first installation gap communicating with the first through hole, and the second through hole extending therethrough. After the rotating shaft 41 is inserted into the first through hole, the first fastener is inserted into the second through hole. By adjusting the tightening degree of the first fastener and the second through hole to adjust the gap size of the first installation gap, the first connecting rod 421 and the rotating shaft 41 are relatively fixed, making installation and removal of the first connecting rod 421 and the rotating shaft 41 convenient. The first fastener may be a combination of a bolt and a nut.

[0056] A second bearing is installed at the other end of the first connecting rod 421, and a shoulder is provided at the end of the support rod 31. The support rod 31 passes through the bearing hole of the second bearing, and the shoulder is in conflict with one side of the first connecting rod 421. A shaft retaining ring is installed at a position corresponding to the other side of the first connecting rod 421 on the support rod 31, thereby realizing the rotational connection between the support rod 31 and the first connecting rod 421.

[0057] In an embodiment of the present invention, the first connecting member 42 includes a first connecting rod 421 and a first fastener. One end of the first connecting rod 421 is provided with a first through hole and a second through hole. The first through hole is connected to the first installation gap. The rotating shaft 41 is passed through the first through hole. The size of the first installation gap is adjusted by adjusting the tightness of the first fastener and the second through hole. The first connecting rod 421 and the rotating shaft 41 are easy to install and disassemble.

[0058] like Figure 1 and Figure 3 As shown, in an optional embodiment, the guide mechanism 5 includes a guide shaft 51, a guide seat 52 and a second connecting member 53; the guide seat 52 is connected to the central shaft 12, the guide seat 52 has a guide groove, and the second connecting member 53 is used to connect the support rod 31 and the guide shaft 51, the guide shaft 51 is passed through the guide groove, and can slide along the extension direction of the guide groove.

[0059] Specifically, the guide seat 52 is connected to the central shaft 12 and is provided with a guide groove, the axis of which is perpendicular to the axis of the support rod 31. A guide bearing is mounted in the guide groove. One end of the guide shaft 51 is connected to the support rod 31 via a second connecting member 53. The guide shaft 51 passes through the guide bearing and can slide along the extension direction of the guide bearing.

[0060] The rotating shaft 41 drives the first connecting member 42 to rotate toward the central axis 12. The rotating force applied by the first connecting member 42 causes the support rod 31 to move toward the central axis 12. The support rod 31 applies a thrust to the guide shaft 51 through the second connecting member 53, causing the guide shaft 51 to slide toward the guide groove. As a result, the support rod 31 can stably move toward the central axis 12 under the guidance of the guide shaft 51. The rotating shaft 41 drives the first connecting member 42 to rotate toward the direction away from the central axis 12. The rotating force applied by the first connecting member 42 causes the support rod 31 to move toward the direction away from the central axis 12. The support rod 31 applies a pulling force to the guide shaft 51 through the second connecting member 53, causing the guide shaft 51 to slide toward the direction away from the guide groove. As a result, the support rod 31 can stably move toward the direction away from the central axis 12 under the guidance of the guide shaft 51.

[0061] In an embodiment of the present invention, the guide shaft 51 is connected to the support rod 31 through a second connecting member 53. The guide shaft 51 is inserted into the guide groove and can reciprocate along the extension direction of the guide groove, thereby driving the support rod 31 to reciprocate stably, which is beneficial to the smooth movement of the adsorption mechanism 3.

[0062] like Figure 1 and Figure 3 As shown, in an optional embodiment, the second connecting member 53 includes a second connecting rod 531 and a second fastener; the second connecting rod 531 is provided with a third through hole and a fourth through hole, the support rod 31 is passed through the third through hole, and the second fastener is passed through the fourth through hole, for realizing a detachable connection between the second connecting rod 531 and the support rod 31.

[0063] Specifically, the second connecting member 53 is used to connect the guide shaft 51 and the support rod 31. The second connecting member 53 includes a second connecting rod 531 and a second fastener. The second connecting rod 531 is provided with a third through hole and a fourth through hole. The axes of the third through hole and the fourth through hole are perpendicular. The inner diameter of the third through hole matches the diameter of the support rod 31. A second installation gap is defined at the end of the second connecting rod 531. The second installation gap is connected to the third through hole, and the fourth through hole extends through the second installation gap. After the support rod 31 is inserted into the third through hole, the second fastener is inserted into the fourth through hole. By adjusting the tightening degree of the second fastener and the fourth through hole to adjust the gap size of the second installation gap, the second connecting rod 531 and the support rod 31 are relatively fixed, and the second connecting rod 531 and the support rod 31 are conveniently installed and removed. The second fastener can be a combination of a bolt and a nut. One end of the guide shaft 51 can be threadedly connected to the second connecting rod 531.

[0064] like Figure 1 、 Figure 2 and Figure 3 As shown, in an optional embodiment, the adsorption member 32 includes an adsorption unit and an air path unit, a plurality of adsorption units are arranged at intervals on the support rod 31, and the plurality of adsorption units are connected to the plurality of air path units in a one-to-one correspondence.

[0065] Specifically, the suction element 32 includes a suction unit and an air circuit unit. The suction unit includes a suction nozzle, and the air circuit unit is used to provide a negative pressure environment and a positive pressure environment for the suction unit. The suction unit and the air circuit unit are connected one-to-one, and each suction nozzle has an independent air circuit. For example, five suction nozzles are installed at intervals on the support rod 31, and the five suction nozzles are connected one-to-one to the five air circuits.

[0066] The adsorption mechanism 3 rotates to the first station with the turntable 11, and the suction nozzle end is under negative pressure. Five suction nozzles suck five medicine boards, among which there are qualified medicine boards and unqualified medicine boards; the adsorption mechanism 3 rotates to the second station with the turntable 11, and the air circuit unit provides positive pressure for the suction nozzles adsorbed with the unqualified medicine boards, and the unqualified medicine boards are separated from the suction nozzles and fall into the collection bin under the action of gravity; the adsorption mechanism 3 rotates to the third station with the turntable 11, and the air circuit unit provides positive pressure for the suction nozzles adsorbed with the qualified medicine boards, and the qualified medicine boards are separated from the suction nozzles and fall onto the conveyor belt under the action of gravity and are further transported to the packaging station.

[0067] In an embodiment of the present invention, a plurality of adsorption units are arranged at intervals on the support rod 31, and the adsorption units are connected one-to-one with the air path units. When the adsorption mechanism 3 rotates one circle with the turntable 11, after the medicine plates are absorbed, it is helpful to remove unqualified medicine plates and transfer qualified medicine plates to the conveying station, which is helpful to improve the transfer efficiency of the medicine plates.

[0068] like Figure 1 、 Figure 2 and Figure 3 As shown, in an optional embodiment, there are multiple adsorption mechanisms 3 , and the multiple adsorption mechanisms 3 are arranged in a circumferential direction around the axis of the central axis 12 .

[0069] Specifically, the number of adsorption mechanisms 3 is set according to actual needs. For example, there are three adsorption mechanisms 3, and the three adsorption mechanisms 3 are arranged circumferentially around the axis of the central axis 12. It is understood that the number of guide mechanisms 5 is also three, and the three guide seats 52 are arranged in sequence along the axis of the central axis 12. The installation position of the second connecting rod 531 on the support rod 31 corresponds to the position of the guide seat 52 on the central axis 12, ensuring that the guide axis 51 is perpendicular to the central axis 12 and perpendicular to the support rod 31.

[0070] The three rotating shafts 41 are evenly distributed in the circumferential direction around the axis of the central axis 12, and the three first gears 43 are connected to the three rotating shafts 41 in a one-to-one correspondence. The three first gears 43 are all meshed and connected with the second gear 44. Therefore, when the second gear 44 rotates with the turntable 11, the three first gears 43 rotate at the same time, and the three rotating shafts 41 rotate with the first gears 43 connected thereto, thereby driving the three first connecting members 42 to move simultaneously.

[0071] When the turntable 11 rotates, the three adsorption mechanisms 3 operate simultaneously. One adsorption mechanism 3 absorbs the cut medicine plates at the first station, one adsorption mechanism 3 places the unqualified medicine plates in the collection bin at the second station, and one adsorption mechanism 3 places the qualified medicine plates on the conveyor belt at the third station, which is conducive to further improving the working efficiency of the transfer device.

[0072] In the embodiment of the present invention, the plurality of adsorption mechanisms 3 are arranged in a circumferential direction around the axis of the central axis 12 . The plurality of adsorption mechanisms 3 operate simultaneously as the turntable 11 rotates, which is beneficial to further improve the working efficiency of the transfer device.

[0073] like Figure 2 、 Figure 3 and Figure 4 As shown, in an optional embodiment, the transfer device also includes a sealing cylinder 6; the rotating shaft 13 is embedded in the sealing cylinder 6, and a plurality of air flow channels 131 are arranged at intervals around the axis of the rotating shaft 13 on the rotating shaft 13, and the inlet of the air flow channel 131 and the outlet of the air flow channel 131 are arranged on opposite sides of the turntable 11.

[0074] Specifically, the rotating shaft 13 is provided with a plurality of airflow channels 131. The number of airflow channels 131 is set according to actual needs. The plurality of airflow channels 131 are arranged circumferentially and spaced apart around the axis of the rotating shaft 13. The inlet of the airflow channel 131 is located on the second side of the turntable 11, and the outlet of the airflow channel 131 is located on the first side of the turntable 11. The inlet of the airflow channel 131 is connected to the vacuum generator via the sealing cylinder 6, and the outlet of the airflow channel 131 is connected to the suction nozzle via an air pipe. For example, if there are three suction mechanisms 3 and each support rod 31 is equipped with five suction nozzles, there are fifteen airflow channels 131, and each suction nozzle is provided with an independent air path.

[0075] The rotating shaft 13 is embedded in the sealing cylinder 6. The rotating shaft 13 and the sealing cylinder 6 can be connected by screwing. The sealing cylinder 6 ensures good sealing of the air path and ensures that each air path provides a reliable negative pressure environment or positive pressure environment for the suction nozzle, so that the suction nozzle can firmly adsorb the medicine plate or release the medicine plate.

[0076] In an embodiment of the present invention, the sealing cylinder 6 is coaxially arranged with the rotating shaft 13, and multiple air flow channels 131 are provided on the rotating shaft 13. The inlet of the air flow channel 131 is connected to the vacuum generator through the sealing cylinder 6, and the outlet of the air flow channel 131 is connected to the suction nozzle through the air pipe, which provides an independent air path for each adsorption unit and is conducive to the reasonable layout of the air pipe and the compactness of the structure.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
