Description

Technical Field

[0001] This utility model relates to the field of medicine bottle packaging production technology, and in particular to a medicine bottle dispensing device. Background Technology

[0002] In the production of medicine bottle packaging, medicine bottles coming out of the front station continuously are transported to the back station one after another. When the back station needs to feed bottles non-continuously, a bottle separating device is used to separate the medicine bottles.

[0003] Existing bottle-separating devices mainly consist of a circular separating wheel, a drive shaft, and a drive motor. Bottle separation and transport are achieved by adjusting the speed difference between the circular separating wheel and the conveyor line. However, in actual operation, when the conveyor line stops, the bottles on the conveyor line at the front end of the circular separating wheel continue to move closer to the wheel due to inertia. This causes the bottles to be squeezed and pass through the wheel, affecting the spacing between already separated bottles and resulting in poor separation efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a medicine bottle separating device, which aims to improve the separating effect.

[0005] The technical solution provided by this utility model is as follows:

[0006] A medicine bottle dispensing device, comprising:

[0007] The star-shaped bottle divider wheel has multiple equally spaced notches on its outer circumference and can be in a rotating or stationary state.

[0008] A rotating shaft is inserted at the center of the star-shaped dispensing wheel and moves synchronously with the star-shaped dispensing wheel;

[0009] A magnetic coupler is connected to the rotating shaft;

[0010] When the number of medicines in the medicine bottle queue reaches a preset value, the star-shaped dispensing wheel is in the rotating state under the thrust of the medicine bottle queue; when the number of medicine bottles in the medicine bottle queue does not reach the preset value, the star-shaped dispensing wheel is in the stationary state under the action of the magnetic coupler.

[0011] Furthermore, the medicine bottle dispensing device also includes a conveyor belt, and the star-shaped dispensing wheel is disposed above one side of the conveyor belt.

[0012] Furthermore, the bottle-separating device also includes an adjustment mechanism installed on the side plate of the conveyor belt, under the action of the adjustment mechanism, the star-shaped bottle-separating wheel can move closer to and further away from the conveyor belt.

[0013] Furthermore, the adjustment mechanism includes:

[0014] A threaded rotating rod is arranged perpendicularly to the side plate of the conveyor belt;

[0015] A sliding base is movably mounted on the threaded rotating rod, and the magnetic coupler is mounted on the sliding base. The rotation of the threaded rotating rod causes the sliding base to move along the length direction of the threaded rotating rod.

[0016] Furthermore, the adjustment mechanism also includes a guide rod, which is arranged parallel to the threaded rotating rod, and the sliding base is movably mounted on the guide rod.

[0017] Furthermore, the adjustment mechanism also includes a fixed plate, the threaded rotating rod and the guide rod are mounted on the fixed plate, and the threaded rotating rod is rotatably connected to the fixed plate.

[0018] Furthermore, a mounting plate is provided on the side plate of the conveyor belt, and the adjustment mechanism is mounted on the side plate of the conveyor belt through the mounting plate, which has multiple adjustment holes.

[0019] Furthermore, the number of notches is eight, and a sharp corner is provided between two adjacent notches.

[0020] Furthermore, the width of the notch matches the diameter of the medicine bottle.

[0021] Furthermore, the star-shaped bottle-dividing wheel is detachably connected to the rotating shaft.

[0022] Compared with the prior art, the medicine bottle dispensing device provided in this embodiment of the utility model has at least the following technical advantages:

[0023] The medicine bottle dispensing device includes a star-shaped dispensing wheel, a rotating shaft, and a magnetic coupler. The star-shaped dispensing wheel has multiple equally spaced notches on its outer circumference and can operate in both rotating and stationary states. The rotating shaft passes through the center of the star-shaped dispensing wheel and moves synchronously with it. The magnetic coupler is connected to the rotating shaft. When the number of medicines in the bottle queue reaches a preset value, the star-shaped dispensing wheel rotates under the pushing force of the bottle queue; when the number of medicines in the queue does not reach the preset value, the star-shaped dispensing wheel remains stationary under the action of the magnetic coupler. This design ensures that the star-shaped bottle-separating wheel only begins to rotate and perform bottle separation when the number of bottles in the bottle queue reaches a preset value. When the number of bottles in the queue is less than the preset value, the magnetic coupler effectively prevents the star-shaped bottle-separating wheel from continuing to rotate. This effectively avoids the phenomenon where bottles continue to move closer to the star-shaped bottle-separating wheel due to inertia when the number of bottles in the queue is less than the preset value due to a conveyor line stoppage, thus preventing the bottles from passing through the star-shaped bottle-separating wheel. This ensures that the spacing between separated bottles is not affected, improving the bottle-separating effect. In addition, compared with the circular bottle-separating wheel in the prior art, the star-shaped bottle-separating wheel has multiple evenly spaced notches on its outer circumference, preventing the bottles from being squeezed during the separation process. Unlike the existing technology that relies on a drive motor to drive the circular bottle-separating wheel for bottle separation, the star-shaped bottle-separating wheel relies on the pushing force of the bottle queue to achieve bottle separation, eliminating the need for a motor drive and saving energy.

[0035] Please refer to the attached document. Figure 1 To be continued Figure 3 As shown, one embodiment of this utility model provides a medicine bottle dispensing device, including a star-shaped dispensing wheel 10, a rotating shaft 20, and a magnetic coupler 30. The star-shaped dispensing wheel 10 has multiple equally spaced notches 11 on its outer circumference and has a rotating state and a stationary state. The rotating shaft 20 passes through the center of the star-shaped dispensing wheel 10 and moves synchronously with the star-shaped dispensing wheel 10. The magnetic coupler 30 is connected to the rotating shaft 20. When the number of medicines in the medicine bottle queue reaches a preset value, the star-shaped dispensing wheel 10 is in a rotating state under the pushing force of the medicine bottle queue. The medicine bottles enter from the inlet position of the star-shaped dispensing wheel 10 and are released at the outlet position. When the number of medicines in the medicine bottle queue does not reach the preset value, the star-shaped dispensing wheel 10 is in a stationary state under the action of the magnetic coupler 30.

[0036] The magnetic coupler 30 includes two sets of permanent magnets, with the first set connected to the rotating shaft 20. Torque transmission is achieved through non-contact magnetic coupling between the two sets of permanent magnets. When the number of bottles in the bottle queue reaches a preset value, the bottles exert sufficient force on the star-shaped dispensing wheel 10, causing the first set of permanent magnets connected to the rotating shaft 20 to rotate. This rotation, via magnetic coupling, drives the second set of permanent magnets to rotate synchronously, thus rotating the star-shaped dispensing wheel 10 and performing the dispensing operation. Conversely, when the number of bottles in the bottle queue does not reach the preset value, the force exerted by the bottles on the star-shaped dispensing wheel 10 is insufficient, preventing the first set of permanent magnets connected to the rotating shaft 20 from rotating. In this case, the second set of permanent magnets in the magnetic coupler 30 also cannot be driven to rotate. Simultaneously, due to the characteristics of the magnetic coupler 30, the second set of permanent magnets exerts a damping effect on the first set, thus limiting the movement of the first set and effectively preventing the rotation of the star-shaped dispensing wheel 10. The magnetic coupler 30 allows adjustment of the preset value for the number of medicine bottles by adjusting the torque. The torque can be flexibly set according to the actual production needs of medicine bottles of different specifications.

[0037] In this embodiment, the medicine bottle dispensing device includes a star-shaped dispensing wheel 10, a rotating shaft 20, and a magnetic coupler 30. The star-shaped dispensing wheel 10 has multiple equally spaced notches 11 on its outer circumference and has both a rotating state and a stationary state. The rotating shaft 20 passes through the center of the star-shaped dispensing wheel 10 and moves synchronously with it. The magnetic coupler 30 is connected to the rotating shaft 20. When the number of medicines in the medicine bottle queue reaches a preset value, the star-shaped dispensing wheel 10 rotates under the pushing force of the medicine bottle queue. When the number of medicines in the medicine bottle queue does not reach the preset value, the star-shaped dispensing wheel 10 remains stationary under the magnetic coupling. The star-shaped bottle-separating wheel 10 remains stationary under the action of the magnetic coupler 30. This design ensures that the star-shaped bottle-separating wheel 10 only begins to rotate and perform bottle-separation when the number of bottles in the bottle queue reaches a preset value. When the number of bottles in the bottle queue does not reach the preset value, the magnetic coupler 30 effectively prevents the star-shaped bottle-separating wheel 10 from continuing to rotate. This effectively avoids the phenomenon where bottles continue to approach the star-shaped bottle-separating wheel 10 due to inertia when the number of bottles in the bottle queue does not reach the preset value due to a stop in the conveyor line, thus preventing the bottles from passing through the star-shaped bottle-separating wheel 10. This ensures that the spacing between the separated bottles is not affected, improving the bottle-separation effect. In addition, compared with the circular bottle-separating wheel in the prior art, the outer circumference of the star-shaped bottle-separating wheel 10 is provided with multiple equally spaced notches 11, which prevents the bottles from being squeezed during the bottle-separation process. Unlike the prior art method of relying on a drive motor to drive the circular bottle-separating wheel for bottle separation, the bottle-separating device of the star-shaped bottle-separating wheel 10 relies on the pushing action of the bottle queue to achieve bottle separation, eliminating the need for a motor drive and saving energy.

[0038] It should be further noted that the downstream station of the medicine bottle separating device may include, but is not limited to, a labeling device. The better separating effect provided by this medicine bottle separating device can improve the working efficiency of the subsequent labeling device.

[0039] In some alternative embodiments, the bottle dispensing device further includes a conveyor belt, with a star-shaped dispensing wheel 10 positioned above one side of the conveyor belt. A notch 11 in the star-shaped dispensing wheel 10 forms a channel between itself and the other side of the conveyor belt for the bottles to pass through.

[0040] In some optional embodiments, the bottle-separating device further includes an adjustment mechanism 40 mounted on a side plate of the conveyor belt. Under the action of the adjustment mechanism 40, the star-shaped bottle-separating roller 10 can move closer to or further away from the conveyor belt. Specifically, the adjustment mechanism 40 is mounted on a side plate on one side of the conveyor belt. Through the operation of the adjustment mechanism 40, the star-shaped bottle-separating roller 10 can move closer to or further away from the other side of the conveyor belt along its width. This adjustment process can change the channel size when the bottles pass through the star-shaped bottle-separating roller 10, thereby adapting to the bottle-separating needs of different bottle sizes.

[0041] In some optional embodiments, the adjusting mechanism 40 includes a threaded rotating rod 41 and a sliding base 42; the threaded rotating rod 41 is arranged perpendicularly to the side plate of the conveyor belt; the sliding base 42 is movably mounted on the threaded rotating rod 41, and the magnetic coupler 30 is mounted on the sliding base 42. The rotation of the threaded rotating rod 41 drives the sliding base 42 to move along the length direction of the threaded rotating rod 41, so that the star-shaped bottle-separating wheel 10 can be adjusted in the width direction of the conveyor belt to meet the bottle-separating requirements of different medicine bottle sizes.

[0042] In some optional embodiments, the adjusting mechanism 40 further includes a guide rod 43, which is arranged parallel to the threaded rotating rod 41, and the sliding base 42 is movably mounted on the guide rod 43. In this embodiment, the guide rod 43 allows the sliding base 42 to slide smoothly along it, effectively avoiding offset problems and thus enhancing the accuracy of the star-shaped bottle divider 10's position adjustment in the conveyor belt width direction.

[0043] In some optional embodiments, the adjusting mechanism 40 further includes a fixed plate 44, with a threaded rotating rod 41 and a guide rod 43 mounted on the fixed plate 44, and the threaded rotating rod 41 rotatably connected to the fixed plate 44. Further, the fixed plate 44 is arranged parallel to the side plate of the conveyor belt. The guide rod 43 includes a first guide rod and a second guide rod arranged in parallel, one end of which is fixed to the fixed plate 44, and the other end is mounted on the side plate of the conveyor belt. The threaded rotating rod 41 is arranged parallel between the first guide rod and the second guide rod, and both ends are rotatably connected to the fixed plate 44 and the side plate of the conveyor belt, respectively. One end of the threaded rotating rod 41 near the fixed plate 44 extends to the outside of the fixed plate 44 and can be connected to a knob, allowing the user to manually rotate the threaded rotating rod 41 by rotating the knob. Furthermore, the end of the threaded rotating rod 41 near the fixed plate 44 extending to the outside of the fixed plate 44 can also be connected to a motor, enabling automatic rotation under motor drive. With this design, users can easily adjust the position of the sliding base 42 by manually or electrically rotating the threaded rotating rod 41, thereby realizing the position of the star-shaped bottle divider 10 in the width direction of the conveyor belt.

[0044] In some optional embodiments, a mounting plate 50 is provided on the side plate of the conveyor belt, and the adjustment mechanism 40 is mounted on the side plate of the conveyor belt through the mounting plate 50. The mounting plate 50 is provided with a plurality of adjustment holes 51 to facilitate the adjustment of the position of the star-shaped bottle-separating wheel 10 in the length direction of the conveyor belt, so as to adapt to the bottle-separating requirements of different specifications of medicine bottles and improve the applicability of the bottle-separating device.

[0045] In some optional embodiments, the number of notches 11 is, but not limited to, eight. Further, a pointed corner 12 is provided between adjacent notches 11 to facilitate insertion between adjacent medicine bottles, thereby effectively separating the bottles. The specifications of the star-shaped bottle-separating wheel 10 can be designed according to the specific requirements of the required bottle spacing. By adjusting the number, size, and spacing of the notches 11, the bottle-separating needs of different sized medicine bottles can be met. This flexible design allows the bottle-separating device to adapt to various production requirements, achieving optimal bottle-separating results regardless of the size and shape of the medicine bottles or the rhythm of the production line.

[0046] In some optional embodiments, the width of the notch 11 matches the diameter of the medicine bottle. The medicine bottle is circular, and the notch 11 is arc-shaped. In this embodiment, by matching the width of the notch 11 to the diameter of the medicine bottle, the medicine bottle is more stably positioned in the star-shaped bottle-separating wheel 10, reducing the risk of the bottle tilting during the separation process and further ensuring the normal operation of subsequent workstations.

[0047] In some optional embodiments, the star-shaped dispensing wheel 10 is detachably connected to the rotating shaft 20, facilitating easy disassembly and reassembly of the star-shaped dispensing wheel 10 when replacement is required. The specifications of the star-shaped dispensing wheel 10 can be designed according to the size, shape, and material of the medicine bottle to meet the dispensing needs of different sized medicine bottles. For example, it is suitable for round, square, or other special-shaped medicine bottles. The star-shaped dispensing wheel 10 is bolted to the rotating shaft 20, ensuring a secure and reliable connection while facilitating disassembly and replacement.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
