Description

Technical Field

[0001] The present invention belongs to the technical field of drug packaging box conveying, and particularly relates to a conveying device for drug packaging boxes. Background Art

[0002] As the name implies, a drug packaging box is a box for packaging drugs. During the processing of drug packaging boxes, a conveying device is needed to convey a large number of drug packaging boxes. As a key link in drug production, the production efficiency and quality of drug packaging directly affect the safety and market competitiveness of drugs. The drug packaging box conveying device is the core component of the drug packaging production line. With the rapid development of the pharmaceutical industry, the varieties of drugs are becoming increasingly rich, and the packaging specifications are also showing a diversified trend.

[0003] After the existing drug packaging boxes are placed on the conveying device, their positions on the conveyor belt are often incorrect, which makes it difficult to accurately load drugs into the drug packaging boxes subsequently; and some types of drug packaging boxes need to be turned over and labeled on the conveying device, but the turning structure on the traditional conveying device is often specially designed for the width of the drug packaging boxes and cannot be applied to packaging boxes of different widths, resulting in a very limited application range of the drug packaging box conveying device; at the same time, after the drug packaging boxes are placed on the conveying device, the distances between adjacent two groups of drug packaging boxes are uneven, which is not convenient for the subsequent automatic drug loading device to load drugs into the packaging boxes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a conveying device for drug packaging boxes.

[0005] The technical solution adopted to solve the above technical problem is: a conveying device for drug packaging boxes, including a main frame as an installation carrier, a conveying mechanism for conveying drug packaging boxes is arranged inside the main frame, a shunting mechanism is arranged on the top of the main frame, a turning mechanism is arranged at the middle position inside the main frame, a material blocking mechanism is arranged at a position on the top of the main frame close to the shunting mechanism, and a limiting mechanism is arranged at the same end of both sides inside the main frame.

[0006] Furthermore, the conveying mechanism includes two rows of conveying rollers at both ends inside the main frame, a conveyor belt is jointly arranged outside the two rows of conveying rollers, a first servo motor for driving a group of conveying rollers to rotate is installed at one end of one side of the main frame, and auxiliary conveyor belts are symmetrically arranged at both ends outside each row of conveying rollers.

[0007] Through the above technical solution, the first servo motor is controlled to drive the two rows of conveying rollers to rotate in cooperation with the conveyor belt, and the medicine packaging boxes can be stably conveyed by using the conveyor belt. The auxiliary conveyor belts on each row of conveying rollers can prevent the medicine packaging boxes from accidentally getting stuck in the gap between the conveyor belt and the main body frame, and when the auxiliary conveyor belts rotate, it will also make it easier for the medicine packaging boxes to leave the U-shaped card slots.

[0008] Further, the diversion mechanism includes a first U-shaped frame located at the middle position on the top of the main body frame. A bidirectional lead screw is arranged at the middle position inside the first U-shaped frame. L-shaped plates are symmetrically threaded on the outer side of the bidirectional lead screw. The same ends of the two groups of L-shaped plates are symmetrically hinged with diversion plates. The ends of the two groups of diversion plates away from the L-shaped plates are hinged to each other. A first slide rod passing through the two groups of L-shaped plates is installed at one end inside the first U-shaped frame. A second servo motor for driving the bidirectional lead screw to rotate is installed on one side of the first U-shaped frame.

[0009] Through the above technical solution, the second servo motor is controlled to drive the bidirectional lead screw to rotate. By using the thread action, the two groups of L-shaped plates are forced to move away from each other, and the distance between the L-shaped plates and the limiting plate is adjusted to conform to the width of the medicine packaging box. The diversion plates can guide the two columns of medicine packaging boxes on the conveyor belt to the outside of the two groups of L-shaped plates. When the limiting plate is located in the hidden groove, the vertical distance between the L-shaped plates and the turntable can be adjusted to conform to the width of the medicine packaging box, so that one side of the medicine packaging box can be accurately inserted into the U-shaped card slot.

[0010] Further, the turning-over mechanism includes grooves symmetrically opened on both sides inside the first U-shaped frame. Rotatable turntables are symmetrically arranged on the inner walls of the two groups of grooves. Four U-shaped card slots are symmetrically and evenly arranged on the opposite faces of the two groups of turntables. A driving component for driving the two groups of turntables to rotate synchronously is arranged inside the grooves.

[0011] Through the above technical solution, the third servo motor is controlled to drive one turntable to rotate 90° each time. The medicine packaging boxes divided into two columns on the conveyor belt will be respectively inserted into the U-shaped card slots on the two groups of turntables. Along with the rotation of the turntables, and in cooperation with the L-shaped plates, the medicine packaging boxes can be turned over. The turned-over medicine packaging boxes fall onto the conveyor belt and the auxiliary conveyor belts and are conveyed away again.

[0012] Further, the driving component includes a first rotating rod rotatably arranged at one end inside the first U-shaped frame. The first rotating rod passes through the two groups of L-shaped plates. Transmission gears are symmetrically installed at both ends on the outer side of the first rotating rod. Annular racks meshing with the transmission gears are symmetrically installed on the outer circles of the two groups of turntables. A third servo motor for driving the adjacent turntable to rotate is installed on one side of the main body frame.

[0013] Through the above technical solution, the third servo motor is controlled to drive a group of turntables to rotate 90° each time. When the turntable rotates, the turntable drives the first rotating rod to rotate through the transmission of the annular rack and the transmission gear, thereby making the two groups of turntables rotate synchronously.

[0014] Furthermore, the material blocking mechanism includes a second U-shaped frame located at the top of the main frame near the position of the first U-shaped frame, a rotatable second rotating rod is provided at the middle position inside the second U-shaped frame, circular plates are symmetrically installed at both ends of the outer side of the second rotating rod, and two groups of toggle blocks are symmetrically installed on the outer circles of the two groups of circular plates, automatic reset components that cooperate with the toggle blocks are symmetrically provided at both ends inside the second U-shaped frame, and the second rotating rod is connected to the first rotating rod through a transmission mechanism.

[0015] Through the above technical solution, when the first rotating rod drives the second rotating rod to rotate through the transmission mechanism, the second rotating rod will also drive the two groups of circular plates to rotate synchronously. During this process, the two groups of toggle blocks on the outer rings of the two groups of circular plates will push one group of lifting plates to rise and the other group of lifting plates to fall. As the second rotating rod drives the two groups of circular plates to rotate continuously, the two groups of lifting plates will be forced to continuously perform reciprocating lifting and lowering motions.

[0016] Furthermore, the automatic reset component includes four groups of second sliding rods located at the four corners inside the second U-shaped frame, the bottom ends of the second sliding rods are equipped with a base fixedly connected to the side walls of the second U-shaped frame, and the outer sides of the two groups of second sliding rods at the same end are jointly sleeved with a lifting plate, and the two groups of lifting plates are centrally symmetrical, and the outer sides of the second sliding rods are sleeved with a reset spring, the top and bottom of a pair of reset springs are respectively fixedly connected to the second U-shaped frame and the lifting plate, and the top and bottom of another pair of reset springs are respectively fixedly connected to the lifting plate and the base, baffles are symmetrically installed on both sides of the bottom of one group of lifting plates, and two groups of baffles are provided on the bottom of the other group of lifting plates through an adjusting component.

[0017] Through the above technical solution, when the toggle block toggles one set of lifting plates to rise, the other set of lifting plates is toggled down. During the process, the lifting plates slide on the second slide rod, and the reset spring continuously switches between the contracted and extended states, so that after the toggle block leaves the lifting plates, the lifting plates can automatically reset. As the two sets of lifting plates continue to rise and fall back and forth, two pairs of baffles can be used to allow the medicine packaging boxes to be transported at a fixed distance on the conveyor belt.

[0018] Furthermore, the adjustment component includes limiting slide grooves symmetrically opened on both sides of the lifting plate, a limiting slider is arranged inside the limiting slide groove, and a connecting plate fixedly connected to the top of the two groups of limiting sliders is provided on the top of the lifting plate. The tops of the two groups of baffles at the same end are respectively fixedly connected to the bottoms of the two groups of limiting sliders, and the top thread of the connecting plate is provided with a butterfly screw.

[0019] Through the above technical solution, manually move a pair of baffles connected thereto closer to another pair of baffles through the connecting plate until the distance between the two pairs of baffles conforms to the width of the medicine packaging box, and then manually tighten the butterfly screw to fix the connecting plate, which helps to convey medicine packaging boxes of different lengths on the conveyor belt at fixed intervals. During the process, the limit slider slides inside the limit chute.

[0020] Further, the transmission mechanism includes a first synchronous pulley located at one end of the second rotating rod. One end of the first rotating rod extends to the outside of the first U-shaped frame and is provided with a second synchronous pulley, and a synchronous belt is commonly arranged outside the second synchronous pulley and the first synchronous pulley.

[0021] Through the above technical solution, each time the first rotating rod rotates, the first rotating rod drives the second rotating rod to rotate through the cooperation of the first synchronous pulley, the second synchronous pulley and the synchronous belt. Furthermore, after the turntable rotates 90° each time, the second rotating rod will drive the circular plate to rotate one circle, so that the lifting of the baffle is linked with the rotation of the turntable.

[0022] Further, the limiting mechanism includes hidden grooves symmetrically opened on both sides inside the main body frame. Limiting plates are symmetrically arranged inside the two groups of hidden grooves. Third sliding rods are symmetrically installed at both ends of the mutually remote sides of the two groups of limiting plates, and the third sliding rods extend to the outside of the main body frame and are installed with anti-disengagement blocks. Electric push rods are symmetrically installed on both sides of the main body frame, and the output ends of the electric push rods extend to the inside of the main body frame and are fixedly connected to the middle positions of the adjacent group of limiting plates.

[0023] Through the above technical solution, control the electric push rod to push the limiting plate out of the hidden groove, so that the limiting plate blocks the U-shaped card slot, and then cooperate to adjust the position of the L-shaped plate, so as to adjust the distance between the L-shaped plate and the limiting plate to conform to the width of the medicine packaging box to be conveyed, so that the limiting plate cooperates with the L-shaped plate to automatically correct the position of the medicine packaging box. After controlling the limiting plate to return to the hidden groove, one side of the medicine packaging box can be inserted into the U-shaped card slot.

[0024] The beneficial effects of the present invention are as follows: (1) By the combined use of the conveying mechanism, the shunting mechanism and the limiting mechanism, during the process of the conveying mechanism conveying the medicine packaging boxes, the distance between the L-shaped plate and the limiting plate can be freely controlled, and the positions of the medicine packaging boxes of different sizes can be straightened by the guidance of the shunting plate, so as to facilitate the subsequent medicines to be more accurately loaded into the medicine packaging boxes; (2) Through the turning mechanism, the medicine bottle packaging boxes on the conveyor belt can be automatically turned over, and in combination with the shunting mechanism, the medicine packaging boxes of different width sizes can be turned over, improving the applicable range of the conveying device. And by controlling whether the limiting plate extends out or not, it can be controlled whether the medicine packaging box can be turned over by the turning mechanism, so that the conveying device can freely switch between the turning mode and the non-turning mode; (3) Through the material blocking mechanism, the medicine packaging boxes on the conveyor belt can be blocked and released one by one, so that the distance between adjacent medicine packaging boxes on the conveyor belt is always the same. And since the driving force of the material blocking mechanism comes from the transmission of the turning mechanism through the transmission mechanism, the adjacent medicine packaging boxes can always maintain a fixed distance whether the conveying device is in the turning mode or the non-turning mode, which is convenient for the subsequent automatic medicine loading device to load the medicines into the packaging boxes. At the same time, the material blocking mechanism can further improve the stability and orderliness of the process of inserting one side of the medicine packaging box into the U-shaped card slot.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be 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 the present invention and are not intended to limit the present invention.

[0028] like Figures 1 - 5 、 Figure 8 and Figure 13As shown in the figure, a conveying device for a medicine packaging box according to this embodiment includes a main frame as an installation carrier. Inside the main frame 1, a conveying mechanism 2 for conveying the medicine packaging box is provided. At the top of the main frame 1, a shunting mechanism 3 is provided. At the same end of both sides inside the main frame 1, a limiting mechanism 8 is provided. The conveying mechanism 2 includes two rows of conveying rollers 201 at both ends inside the main frame 1. A conveyor belt 202 is commonly provided on the outer sides of the two rows of conveying rollers 201. At one end of one side of the main frame 1, a first servo motor 203 for driving a group of conveying rollers 201 to rotate is installed. At both ends of the outer side of each row of conveying rollers 201, auxiliary conveyor belts 6 are symmetrically arranged. The shunting mechanism 3 includes a first U-shaped frame 301 at the middle position at the top of the main frame 1. At the middle position inside the first U-shaped frame 301, a bidirectional lead screw 302 is provided. And on the outer side of the bidirectional lead screw 302, L-shaped plates 303 are symmetrically threaded. And at the same end of the two groups of L-shaped plates 303, shunting plates 304 are symmetrically hinged. The ends of the two groups of shunting plates 304 away from the L-shaped plates 303 are hinged to each other. At one end inside the first U-shaped frame 301, a first slide bar 305 passing through the two groups of L-shaped plates 303 is installed. On one side of the first U-shaped frame 301, a second servo motor 306 for driving the bidirectional lead screw 302 to rotate is installed. The limiting mechanism 8 includes hidden grooves 801 symmetrically opened on both sides inside the main frame 1. Inside the two groups of hidden grooves 801, limiting plates 802 are symmetrically provided. At both ends of the mutually remote sides of the two groups of limiting plates 802, third slide bars 803 are symmetrically installed. And the third slide bars 803 extend to the outside of the main frame 1 and anti-detachment blocks are installed. On both sides of the main frame 1, electric push rods 804 are symmetrically installed. The output ends of the electric push rods 804 extend into the main frame 1 and are fixedly connected to the middle position of the adjacent group of limiting plates 802. Control the first servo motor 203 to cooperate with the conveyor belt 202 to drive the two rows of conveying rollers 201 to rotate. The medicine packaging box can be stably conveyed by using the conveyor belt 202. And the auxiliary conveyor belts 6 on each row of conveying rollers 201 can prevent the medicine packaging box from accidentally getting stuck in the gap between the conveyor belt 202 and the main frame 1. And when the auxiliary conveyor belts 6 rotate, it will also make it easier for the medicine packaging box to leave the U-shaped card slot 403. Control the second servo motor 306 to drive the bidirectional lead screw 302 to rotate. By using the thread action, the two groups of L-shaped plates 303 are forced to move away from each other. Adjust the distance between the L-shaped plates 303 and the limiting plates 802 to conform to the width of the medicine packaging box. The shunting plates 304 can guide the two columns of medicine packaging boxes on the conveyor belt 202 to the outside of the two groups of L-shaped plates 303. And when the limiting plates 802 are located inside the hidden grooves 801, the vertical distance between the L-shaped plates 303 and the turntable 402 can be adjusted to conform to the width of the medicine packaging box. In this way, one side of the medicine packaging box can be accurately inserted into the U-shaped card slot 403.

[0029] As Figures 4 - 7 and Figure 13As shown, a flipping mechanism 4 is provided at the middle position of the inner side of the main frame 1 of this embodiment, and the flipping mechanism 4 includes grooves 401 symmetrically opened on both sides of the first U-shaped frame 301, and the inner walls of the two groups of grooves 401 are symmetrically provided with rotatable turntables 402, and the two groups of turntables 402 are symmetrically and evenly provided with four groups of U-shaped slots 403 on the opposite surfaces. A driving assembly 404 for driving the two groups of turntables 402 to rotate synchronously is provided on the inner side of the groove 401, and the driving assembly 404 includes a first rotating rod 4041 rotatable at one end inside the first U-shaped frame 301, the first rotating rod 4041 passes through the two groups of L-shaped plates 303, and transmission gears 4042 are symmetrically installed at both ends of the outer side of the first rotating rod 4041, and the outer rings of the two groups of turntables 402 are symmetrically installed with the transmission gears 404. 2 are meshed with each other. A third servo motor 4044 is installed on one side of the main frame 1 to drive the rotation of an adjacent group of turntables 402. The third servo motor 4044 is controlled to drive one group of turntables 402 to rotate 90 degrees each time. When the turntables 402 rotate, the turntables 402 drive the first rotating rod 4041 to rotate through the annular rack 4043 and the transmission gear 4042, thereby causing the two groups of turntables 402 to rotate synchronously. The medicine packaging boxes divided into two rows on the conveyor belt 202 will be inserted into the U-shaped slots 403 on the two groups of turntables 402 respectively. As the turntables 402 rotate, the L-shaped plate 303 can be used to turn the medicine packaging boxes over. The turned medicine packaging boxes fall onto the conveyor belt 202 and the auxiliary conveyor belt 6 to be transported away again.

[0030] like Figures 9 - 14As shown, a blocking mechanism 5 is provided at a position near the diversion mechanism 3 on the top of the main frame 1 of this embodiment, and the blocking mechanism 5 includes a second U-shaped frame 501 located at the top of the main frame 1 near the first U-shaped frame 301, and a rotatable second rotating rod 502 is provided at the middle position inside the second U-shaped frame 501, and circular plates 503 are symmetrically installed at both ends of the outer side of the second rotating rod 502, and two groups of toggle blocks 504 are symmetrically installed on the outer rings of the two groups of circular plates 503, and automatic reset components 505 that cooperate with the toggle blocks 504 are symmetrically provided at both ends of the interior of the second U-shaped frame 501, and the second rotating rod 502 is connected to the first rotating rod 4041 through the transmission mechanism 7. The automatic reset component 505 includes four positions at the four corners inside the second U-shaped frame 501 The four groups of second sliding rods 5051 are arranged at the bottom ends of the second sliding rods 5051, and a base 5052 is installed at the bottom ends of the second sliding rods 5051, which is fixedly connected to the side walls of the second U-shaped frame 501. A lifting plate 5053 is sleeved on the outer sides of the two groups of second sliding rods 5051 at the same end, and the two groups of lifting plates 5053 are symmetrical with each other. A return spring 5054 is sleeved on the outer sides of the second sliding rods 5051, and the top and bottom of a pair of return springs 5054 are fixedly connected to the second U-shaped frame 501 and the lifting plate 5053 respectively, and the top and bottom of another pair of return springs 5054 are fixedly connected to the lifting plate 5053 and the base 5052 respectively. Baffles 507 are symmetrically installed on both sides of the bottom of one group of lifting plates 5053, and the bottom of the other group of lifting plates 5053 is provided with two adjustment components 506. The baffle plate 507 is a group of baffles, and the adjustment component 506 includes a limiting slide groove 5061 symmetrically opened on both sides of the lifting plate 5053. A limiting slider 5062 is set inside the limiting slide groove 5061. The top of the lifting plate 5053 is provided with a connecting plate 5063 fixedly connected to the top of the two groups of limiting sliders 5062. The tops of the two groups of baffles 507 at the same end are respectively fixedly connected to the bottoms of the two groups of limiting sliders 5062. The top thread of the connecting plate 5063 is provided with a butterfly screw 5064. The transmission mechanism 7 includes a first synchronous wheel 701 located at one end of the second rotating rod 502. One end of the first rotating rod 4041 extends to the outside of the first U-shaped frame 301 and is installed with a second synchronous wheel 702, and the outer sides of the second synchronous wheel 702 and the first synchronous wheel 701 are connected. The synchronous belt 703 is also provided. The connecting plate 5063 is manually used to move a pair of baffles 507 connected thereto toward the other pair of baffles 507 until the spacing between the two pairs of baffles 507 matches the width of the medicine packaging box. Then the butterfly screw 5064 is manually tightened to fix the connecting plate 5063, which helps to ensure that medicine packaging boxes of different lengths can be transported at fixed intervals on the conveyor belt 202. When the first rotating rod 4041 drives the second rotating rod 502 to rotate through the cooperation of the first synchronous wheel 701, the second synchronous wheel 702 and the synchronous belt 703, the second rotating rod 502 will also drive the two sets of circular plates 503 to rotate synchronously. During the process, the two sets of toggle blocks 504 on the outer rings of the two sets of circular plates 503 will push a set of lifting plates 5053 to rise.The other set of lifting plates 5053 descends, sliding on the second slide bar 5051. The return spring 5054 switches between a contracted and extended state, allowing the lifting plates 5053 to automatically return to their original position after the toggle block 504 leaves the lifting plates 5053. As the second rotating rod 502 drives the two sets of circular plates 503 to rotate continuously, the two sets of lifting plates 5053 are forced to continuously perform a reciprocating lifting motion. The two pairs of baffles 507 also perform a reciprocating lifting motion. The reciprocating lifting of the two pairs of baffles 507 allows the pharmaceutical packaging boxes to be conveyed at a fixed spacing on the conveyor belt 202.

[0031] The working principle of this embodiment is as follows: after the medicine packaging boxes are placed on the conveyor belt 202 in two rows, the first servo motor 203 is controlled to drive the conveyor roller 201 and the conveyor belt 202 to rotate, and the medicine packaging boxes on the conveyor belt 202 are conveyed. If this type of medicine packaging box does not need to be turned over and labeled, the electric push rod 804 is controlled to push the limit plate 802 out of the hidden groove 801, so that the limit plate 802 blocks the U-shaped slot 403, and then the position of the pair of baffles 507 at the bottom of a set of lifting plates 5053 is adjusted by the adjustment component 506, and the two pairs of baffles 507 at the bottom of the two sets of lifting plates 5053 are controlled. 07 is consistent with the width of the medicine packaging box. Then, according to the width of the medicine packaging box, the second servo motor 306 is controlled to drive the bidirectional screw 302 to rotate, forcing the two sets of L-shaped plates 303 to move away from each other, and the distance between the L-shaped plates 303 and the limit plate 802 is adjusted to meet the width of the medicine packaging box. Then, the third servo motor 4044 is used to drive the two sets of turntables 402 to rotate 90 degrees each time, and the first rotating rod 4041 cooperates with the transmission mechanism 7 to drive the second rotating rod 502 to rotate, and the second rotating rod 502 drives the two sets of circular plates 503 to rotate synchronously, and the toggle block 504 is used to toggle the two sets of lifting The plate 5053 moves back and forth on the second slide bar 5051, and the first pair of baffles 507 blocks the medicine packaging boxes on the conveyor belt 202, while the second pair of baffles 507 releases the medicine packaging boxes between the two pairs of baffles 507, so that they continue to move with the conveyor belt 202, and then the first pair of baffles 507 rises to allow the next group of medicine packaging boxes to enter between the two pairs of baffles 507, while the second pair of baffles 507 blocks them, allowing the subsequent medicine packaging boxes to be transported away by the conveyor belt 202 at fixed intervals. After being guided by the diverter plate 304, the medicine packaging boxes are blocked by the first pair of baffles 507 and released by the second pair of baffles. After the plate 507 releases the medicine packaging box, the medicine packaging box passes through the channel between the L-shaped plate 303 and the limit plate 802 and is corrected in position. If the transported medicine packaging box needs to be turned over, the electric push rod 804 is controlled to shorten the limit plate 802 and retract it into the hidden groove 801, and then the distance between the L-shaped plate 303 and the inner wall of the turntable 402 is adjusted to match the width of the medicine packaging box. After the second pair of baffles 507 rises to release the medicine packaging box, one side of the medicine packaging box is inserted into the U-shaped slot 403, and then the turntable 402 rotates 90° twice to turn it over and return it to the conveyor belt 202.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
