Description

Technical Field

[0001] The invention relates to the technical field of information code reading, in particular to an information code reading device for plaster packaging. Background Art

[0002] Plaster packaging is an external container or material used to protect and store plasters. It ensures the integrity, cleanliness and safety of plasters during storage and transportation. Plasters are a commonly used topical medicine and are widely used to treat various pain, inflammation and musculoskeletal problems. Therefore, the design and manufacture of plaster packaging are crucial to ensure the quality of plasters and the patient experience.

[0003] Reading the information code on the plaster packaging is a key link to ensure drug tracking, management and safe use. The information code usually contains important information such as the plaster batch number, production date, expiration date, manufacturer, etc. By reading these information codes, medical institutions and patients can easily obtain detailed information about the plaster, thereby achieving effective supervision and rational use of drugs. This is of great significance for ensuring patient medication safety and improving medical quality and efficiency.

[0004] In the existing technology, although the reading device generally has a wide reading range and a high degree of automation, there are still some shortcomings when processing plaster packages. For example, many reading devices require manual stacking of plaster packages for batch reading.

DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] See also Figure 1-Figure 16 The embodiment of the present invention provides a technical solution: comprising a mounting frame 1, and a conveyor belt 4 and a conveyor roller 10 arranged on the mounting frame 1, an information code reader 11 is installed on the frame of the conveyor roller 10, when the information code on the plaster package needs to be read, the plaster package whose information code needs to be read is first placed on the surface of the conveyor belt 4, and then the conveyor belt 4 and the conveyor roller 10 are started, so that the plaster package moves along the conveyor belt 4 to the conveyor roller 10, when the plaster package moves to the direction of the conveyor roller 10 and is transported by the conveyor roller 10, the information code on the plaster package is read by the information code reader 11 to obtain various information such as the production of the plaster, and the plaster package information code reading device also includes:

[0047] A lifting frame 33 is slidably installed in the slide groove 32 through a lifting mechanism, and a plurality of racks 3 with temporary storage rollers 31 are fixedly arranged on the lifting frame 33. The slide groove 32 is fixedly arranged on the mounting frame 1 between the conveyor belt 4 and the conveyor roller 10. A driving mechanism is also arranged between the lifting mechanism and the conveyor belt 4. When the conveyor belt 4 transports the plaster package toward the conveyor roller 10, the driving mechanism drives the lifting mechanism to gradually increase the height of the plurality of racks 3, so as to realize the arrangement of the plaster package in the vertical direction. During the conveying, the driving mechanism is used to drive the lifting mechanism, so that the lifting frame 33 is gradually raised in the slide groove 32, so that the shelf 3 and the temporary storage roller 31 are gradually raised. After the previous plaster package is conveyed to one of the temporary storage rollers 31 by the conveyor belt 4, the shelf 3 and the temporary storage roller 31 on which the plaster package is placed are raised by one station through the lifting mechanism, so that the temporary storage roller 31 below which no plaster package is placed is moved to be flush with the conveyor belt 4, so as to receive the next plaster package. In this reciprocating manner, the plaster packages can be arranged in the vertical direction.

[0048] The stacking mechanism is arranged on the mounting frame 1 between the frame 3 and the conveying roller 10. After each group of temporary storage rollers 31 is provided with plaster packages and the previous group of plaster packages is stacked, the stacking mechanism is used to realize the stacking action of the plaster packages on each temporary storage roller 31; the plaster packages at different heights can be stacked so that the plaster packages can be stacked in the vertical direction without manual stacking. The plaster packages only need to be conveyed to the conveyor belt 4, and the stacking operation can be automatically performed. The operation is relatively convenient and the use is extremely convenient.

[0049] The blocking mechanism is installed on the mounting frame 1 through the transmission mechanism, and the transmission mechanism is arranged between the superimposing mechanism and the blocking mechanism. When the plaster packages are stacked through the superimposing mechanism, the blocking mechanism is used to block the plaster packages being stacked, and after the plaster packages are stacked, the blocking mechanism is separated from the plaster packages through the transmission mechanism. In the process of stacking the plaster packages, the plaster packages being stacked are blocked by the blocking mechanism, so that the plaster packages being stacked are in the same position without the problem of messy stacking, and after the stacking is completed, the blocking mechanism is separated from the stacked plaster packages. At this time, the plaster packages are transported to the conveying roller 10 by the superimposing mechanism, and the stacked plaster packages are transported as a whole by the conveying roller 10, and the stacked plaster packages are scanned as a whole by the information code reader 11, so that the information codes on multiple plaster packages can be read at one time, and the plaster packages can be automatically stacked before scanning, and there is no need to manually stack and store the scanned plaster packages after scanning, but they are uniformly scanned after the automatic stacking is completed, thereby improving the overall efficiency of information code reading;

[0050] In one embodiment of the present invention, the driving mechanism includes a middle plate 77 fixedly arranged on the surface of the mounting frame 1 located at the bottom of the conveyor belt 4, a dovetail groove 78 opened on the middle plate 77, a sliding seat 73 slidably arranged in the dovetail groove 78, and a worm 71 rotatably arranged on the middle plate 77, a rack 75 is fixedly arranged on the sliding seat 73, a gear 4 76 meshing with the rack 75 is arranged on the surface of one end of the worm 71, and a worm wheel 7 rotatably arranged on the surface of the mounting frame 1 is meshed with the end of the worm 71 away from the gear 4 76, and a gear 7 is installed on the worm wheel 7 through the connecting portion 22. Three 72, gear three 72 is connected to the lifting mechanism, and multiple groups of horizontal plates 41 are arranged on the surface of the conveyor belt 4; when the plaster packaging on it is conveyed by the conveyor belt 4, the horizontal plates 41 on it will also reciprocate with the conveyor belt 4. When the horizontal plates 41 abut against the surface of the sliding seat 73, the horizontal plates 41 will push the sliding seat 73 to slide in the dovetail groove 78, so that the rack 75 and the gear four 76 drive the worm 71 to rotate, and then the gear three 72 is rotated through the worm wheel 7 and the worm 71 via the connecting part 22, thereby driving the lifting mechanism to gradually increase the height of the temporary storage roller 31;

[0051] In another embodiment of the present invention, a second spring 74 is provided on the cross plate 41 through the rotation of the shaft body, and the second spring 74 is slidably provided on the surface of the sliding seat 73 away from the end of one side of the cross plate 41. When the cross plate 41 pushes the sliding seat 73 to slide in the dovetail groove 78, the height of the dovetail groove 78 along the conveyor belt 4 in the opposite direction of the plaster packaging conveying direction gradually decreases. In this way, under the pulling action of the dovetail groove 78, the height of the sliding seat 73 will gradually decrease. Since the height of the cross plate 41 remains unchanged, after the sliding seat 73 moves to the maximum stroke, the sliding seat 73 will separate from the cross plate 41. At this time, the second spring 74 recovers its deformation and quickly pulls the sliding seat 73 back so that it can be against the next cross plate 41. In this reciprocating manner, the sliding seat 73 can alternately contact multiple groups of cross plates 41.

[0052] It should be noted here that when the plaster package is transported by the conveyor belt 4, the specific conveying process is that each horizontal plate 41 thereon is a conveying station. After the plaster package pushed by the previous horizontal plate 41 is pushed onto the temporary storage roller 31, the horizontal plate 41 rotates to the bottom with the conveyor belt 4 and pushes the sliding seat 73. The driving mechanism drives the lifting mechanism to lift the temporary storage roller 31 on which the plaster package is placed at this time, and an empty temporary storage roller 31 is raised to be flush with the conveyor belt 4. Then the next horizontal plate 41 will push the next plaster package to move onto the temporary storage roller 31, and the plaster package is continuously pushed onto the temporary storage roller 31 in this reciprocating manner, and the plaster package is continuously lifted by the lifting mechanism.

[0053] When the worm gear 7 rotates, the connecting portion 22 is used to make the gear 3 72 rotate unidirectionally. When the previous horizontal plate 41 separates from the sliding seat 73, the spring 2 74 recovers its deformation and pulls the sliding seat 73 back to its original position. At this time, the rack 75 and the gear 4 76 produce a transmission effect, but this transmission effect only causes the worm gear 7 to rotate, and does not cause the gear 3 72 to rotate, so that the power is not transmitted to the lifting mechanism. The lifting mechanism does not cause the temporary storage roller 31 to rise, but only after the plaster package is transported to the surface of the temporary storage roller 31, the lifting mechanism will control the temporary storage roller 31 to rise;

[0054] In another embodiment of the present invention, the lifting mechanism includes a gear 2 311 rotatably arranged on the mounting frame 1 and meshing with the gear 3 72, a crank 312 is installed at an eccentric position on the gear 2 311, and the end of the crank 312 away from the gear 2 311 is arranged on the surface of a slider 38 sliding in a track 310, the track 310 is fixedly arranged on the surface of the mounting frame 1, a lifting block 35 is rotatably arranged on the slider 38 through a torsion spring, and a top plate 2 39 is fixedly arranged to abut against the bottom surface of the lifting block 35, a plurality of groups of card slots 34 are provided on the lifting frame 33, and the top plate 2 39 abuts against the end surface of the card slot 34, when the gear 3 72 is rotated When the gear 310 rotates, the second driving gear 311 rotates, thereby rotating the crank 312 thereon. Since the crank 312 is set at an eccentric position on the second gear 311, the crank 312 will drive the slider 38 to reciprocate up and down in the track 310. When the slider 38 moves downward in the track 310, the lifting block 35 rubs against the surface of the slot 34, and the lifting block 35 deflects. When the slider 38 moves upward, due to the setting of the second top plate 39, the lifting block 35 will not deflect downward, but will push the lifting frame 33 upward by the effect of abutting against the end surface of the slot 34, so that the shelf 3 and the temporary storage roller 31 are pushed upward.

[0055] When the slider 38 and the lifting block 35 move downward, in order to prevent the lifting frame 33 from moving downward with the lifting block 35, a connecting seat 37 and a top plate 36 that abuts against the bottom surface of the connecting seat 37 are also rotatably provided on the track 310 through a torsion spring. When the lifting block 35 moves downward, the connecting seat 37 abuts against the end surface of the slot 34 to support the lifting frame 33 so that it does not move downward. When the lifting block 35 lifts the lifting frame 33, the connecting seat 37 contacts the surface of the slot 34 and deflects upward until the lifting block 35 rises to the maximum position, and the connecting base recovers its deformation through the torsion spring and abuts against the end surface of the slot 34 again.

[0056] In another embodiment of the present invention, the stacking mechanism includes a plurality of groups of conveying members 6, which are fixed on the mounting frame 1 and have the same number as the temporary storage rollers 31, and the angles of the plurality of groups of conveying members 6 with the horizontal direction are gradually reduced from top to bottom. When the plurality of groups of temporary storage rollers 31 are raised to the maximum stroke by the lifting mechanism, the plurality of groups of temporary storage rollers 31 correspond to the plurality of groups of conveying members 6 one by one, and the heights of the highest points of the inclined positions of the two corresponding groups of temporary storage rollers 31 and the conveying members 6 are the same. After the plaster packages are placed on all the temporary storage rollers 31 except the bottom one, the plaster packages on each layer of the temporary storage rollers 31 are stacked by the stacking mechanism.

[0057] It should be noted here that when stacking the plaster packages on each layer of the temporary storage roller 31, it is necessary to stop the conveying of the conveyor belt 4 to prevent a large number of plaster packages from being conveyed to the temporary storage roller 31 and causing the problem of being unable to stack. In order to solve this problem, a driving motor 12 and a connecting part 22 are also provided on the mounting frame 1, and the connecting part 22 is slidably arranged on the mounting frame 1 through a spring three 8, and a synchronous belt two 13 is installed between the connecting part 22 and the output end of the motor through a synchronous wheel, and the connecting part 22 is connected to the power input end of the conveyor belt 4, and a fixed block 81 is fixedly arranged on the lifting frame 33. When the lifting mechanism drives the lifting frame 33, the shelf 3 and the temporary storage roller 31 to move upward to the maximum stroke, the fixed block 81 is abutted against the connecting part 22, the spring three 8 contracts and deforms, and the synchronous belt two 13 is relaxed. At this time, the drive of the driving motor 12 is cut off, and the conveyor belt 4 stops rotating;

[0058] At this time, since the conveyor belt 4 stops working, the plaster package has not been placed on the temporary storage roller 31 at the bottom. In order to be able to transport the plaster package to the last temporary storage roller 31 and also to transport the plaster package on the temporary storage roller 31 to the conveying member 6, in another embodiment of the present invention, the blocking mechanism includes a pressure plate 26 slidably arranged on the mounting frame 1 and a blocking plate 27 rotated by a torsion spring on the end of the pressure plate 26, and a transmission mechanism is arranged between the pressure plate 26 and the driven roller 61. When the active roller 62 pushes the plaster package to generate friction with the driven roller 61 to rotate the driven roller 61, the pressure plate 26 and the blocking plate 27 slide downward through the transmission mechanism and separate from the conveying member 6 at the bottom.

[0059] Multiple groups of active rollers 62 and multiple groups of driven rollers 61 are arranged on the multiple groups of conveying members 6. The plaster packaging on the conveying member 6 is conveyed along the multiple groups of driven rollers 61 to the conveying roller 10 through the multiple groups of active rollers 62. The transmission mechanism includes a base plate 2 fixed on the mounting frame 1, a driving ring 24 and a screw rod 214 rotatably arranged on the base plate 2. A synchronous belt 23 is installed between the outer surface of the driving ring 24 and the connecting shaft 213 on one of the driven rollers 61, and the inner part of the driving ring 24 is connected to the connecting shaft 213 of the driven rollers 61. The cavity is formed as an annular groove, and the inner wall and outer wall of the annular groove are respectively provided with a meshing tooth 5 219 and a meshing tooth 4 218. The screw rod 214 is inserted between the meshing tooth 5 219 and the meshing tooth 4 218, and a meshing tooth 1 215 is provided on one end of the screw rod 214. The screw rod 214 is threadedly installed on one end of the contact plate 25 fixedly arranged on the surface of the pressure plate 26. The transmission mechanism also includes a transmission frame 21 slidably arranged on the mounting frame 1, and the pressure plate 26 is slidably embedded in the groove body on the transmission frame 21;

[0060] After the previous group of plaster packages are transported from multiple temporary storage rollers 31 to the corresponding conveying members 6, multiple plaster packages are transported downward along the active rollers 62 on their respective conveying members 6. Since the conveying speeds of the active rollers 62 are the same, and since the angles of the multiple groups of conveying members 6 with the horizontal direction gradually decrease from top to bottom, the distance of the conveying members 6 from top to bottom gradually increases, so that the lowest plaster package will be transported to the position first, and the highest plaster package will be transported to the position last, that is, after all the plaster packages below are stacked up, the highest plaster package will be stacked, and when the highest plaster package is transported by the conveying member 6, the active roller 62 thereon pushes the plaster package to move along the conveying member 6, and when the outer surface of the plaster package contacts the driven roller 61, it causes the driven roller 61 to rotate, thereby driving the drive ring 24 to rotate through the synchronous belt 1 23, and when the drive ring 24 rotates, the meshing tooth 1 215 alternately meshes with the meshing tooth 5 219 and the meshing tooth 4 218, please refer to Fig.15 This will cause the screw rod 214 to rotate forward and reverse alternately. When the screw rod 214 rotates in the first direction, the contact plate 25 on it pushes the pressure plate 26 downward. Since the connecting shaft 213, the synchronous belt 23 and the screw rod 214 are all inclined, the contact plate 25 at this time pushes the pressure plate 26 obliquely downward, so that the movement trajectory of the pressure plate 26 on the mounting frame 1 is obliquely downward, and when it moves obliquely downward, it pushes the transmission frame 21 downward, so that the transmission frame 21 moves downward;

[0061] It should also be noted that the connecting portion 22 includes a gear 1 2201, a clamping plate 2202 and a rotating shaft 2203. A ratchet groove is provided on the inner wall surface of the gear 1 2201. The clamping plate 2202 is arranged on the surface of the rotating shaft 2203 through a torsion spring and the other end thereof abuts against the end surface of the ratchet groove. Between the turbine and the gear 3 72, the rotating shaft 2203 is fixed on the surface of the turbine, and the gear 1 2201 is fixed on the surface of the gear 3 72. When the turbine rotates forward, the clamping plate 2202 abuts against the surface of the ratchet groove, driving the gear 3 72 to rotate, so that the height of the temporary storage roller 31 is raised through the lifting mechanism. When the turbine rotates in the reverse direction, teeth are formed between the clamping plate 2202 and the ratchet groove, and the transmission effect is disconnected.

[0062] Similarly, a connecting portion 22 connected to the power input end of the temporary storage roller 31 is also provided on the frame 3, wherein the gear 1 2201 and the rotating shaft 2203 are both rotatably set on the frame 3, and the rotating shaft 2203 is connected to the power input end of the temporary storage roller 31. The clamping plate 2202 is rotated by the torsion spring and the surface of the rotating shaft 2203 and the other end thereof abuts against the end surface of the ratchet groove. The connecting portion 22 connected to the power input end of the conveyor belt 4 is the same, except that the rotating shaft 2203 is connected to the power input end of the conveyor belt 4. When the transmission frame 21 descends, the transmission frame 21 is provided with meshing teeth 216 and meshing teeth 3 217. At this time, the frame 3 and the temporary storage roller 31 thereon are at the maximum height. At this time, the meshing teeth 3 217 drives the conveyor belt The gear 1 2201 on the connecting part 22 on 4 rotates, thereby rotating the conveyor belt 4, so that the conveyor belt 4 conveys the plaster packages to the temporary storage roller 31 at the bottom. After the conveying is completed, the screw rod 214 rotates in the opposite direction, and the contact plate 25 drives the transmission frame 21 to move upward. At this time, due to the setting of the connecting part 22, the gear 1 2201 on the conveyor belt 4 meshing with the meshing tooth 3 217 will not rotate, while the gear 1 2201 on the temporary storage roller 31 rotates through the meshing mechanism with the meshing tooth 2 216. At this time, multiple groups of temporary storage rollers 31 rotate to move the plaster packages on each temporary storage roller 31 toward the conveying member 6 until all the plaster packages are conveyed to the surface of the conveying member 6, and the plaster packages are continuously stacked through the stacking mechanism.

[0063] When stacking the plaster packages, since the stacking is not completed in one go, the blocking mechanism will be used to block the unstacked plaster packages to prevent the unstacked plaster packages from being transported to the conveying roller 10 in advance for information code reading. When the top conveying member 6 transports the plaster packages and rotates the screw 214, the resistance rod presses the pressure plate 26 downward, causing the pressure plate 26 and the blocking plate 27 to move obliquely downward, and in the process of moving, push the stacked plaster packages toward the position of the conveying member 6, so that when the plaster package on the top conveying member 6 slides down, it can just fall on the top of the stacked plaster packages, thereby achieving stacking. After the overall stacking is completed, the blocking plate 27 abuts against the surface of the bottom conveying member 6. , the torsion spring on it is deformed, and the blocking plate 27 is deflected until the blocking plate 27 is deflected ninety degrees to form a channel. At this time, under the drive of the bottom conveying member 6, the stacked plaster packages are conveyed to the conveying roller 10 for information code reading. The blocking plate 27 can be used to block the unstacked plaster packages, and when the plaster packages on the top conveying plate are conveyed, the stacked plaster packages are pushed directly below the top conveying member 6 through the oblique downward movement of the pressure plate 26 and the blocking plate 27, so that the top plaster packages fall and can be directly stacked, and after the stacking is completed, they can bend to form a channel for the stacked plaster packages to pass through. The set blocking plate 27 has multiple effects, which improves the stacking effect of the plaster packages.

[0064] In order to allow the blocking plate 27 to be bent smoothly, the height of the contact position between the blocking plate 27 and the pressure plate 26 through the torsion spring is lower than the height of the conveying member 6 located at the bottom;

[0065] In order to prevent the active roller 62 from pushing the plaster shell to contact with the driven roller 61, the outer peripheral sides of the driven roller 61 and the active roller 62 on the top conveying member 6 are respectively provided with belts 210, and the belt 210 outside the driven roller 61 is provided with two protruding blocks 211, and the belt 210 outside the active roller 62 is provided with a push block 28. When the plaster package enters the top temporary storage roller 31, the push block 28 pushes the plaster package to move on the conveying member 6, and then pushes the protruding block 211 to rotate the driven roller 61. After the plaster package is separated from the protruding block 211, in order to enable the next protruding block 211 to rotate to the initial position with the belt 210, a protrusion 29 is further provided on the belt 210. The protrusion 29 is made of rubber material to increase the friction with the plaster shell, thereby preventing the protruding block 211 from separating from the plaster package and preventing the plaster package from stopping rotating directly.

[0066] When the plaster packages on the temporary storage rollers 31 are conveyed to the conveying member 6, in order to enable the multiple groups of temporary storage rollers 31 to descend quickly, a vertical rod 9 is fixedly provided on the end of the transmission frame 21 near the connecting seat 37, and a lifting rod 91 is rotatably installed on the vertical rod 9 through a torsion spring. The connecting seat 37 and the lifting block 35 are both provided with through grooves, and the through grooves are all arranged in a U-shape. The opening positions of the U-shaped through grooves are arranged at the ends of the connecting seat 37 and the lifting block 35 near the card slot 34. When the vertical rod 9 descends, the two lifting rods 91 are against the connecting seat 37 and the lifting block 35, and the torsion spring is deformed, so that the lifting rod 91 passes over the connecting seat 37 and the lifting block 35, and then as the transmission frame 21 moves upward, the lifting rod 91 moves upward, and the lifting rod 91 is inserted into the connecting seats 37 and the lifting blocks 35 respectively after being deformed by the torsion spring. The connecting seat 37 and the lifting block 35 are placed in the U-shaped through grooves on the connecting seat 37 and the lifting block 35, thereby causing the connecting seat 37 and the lifting block 35 to flip upward. In order to prevent the lifting frame 33 from limiting the upward flipping of the connecting seat 37 and the lifting block 35, a spring 212 is provided on the top surface of the lifting frame 33 located in the slide groove 32. The spring 212 can be slightly deformed so that the lifting frame 33 can move slightly upward, thereby providing space for the connecting seat 37 and the lifting block 35 to flip upward. Then the connecting seat 37 and the lifting block 35 are separated from the card slot 34. Under the action of gravity, the lifting frame 33 falls back quickly, and the multiple temporary storage rollers 31 return to their original positions. At this time, the spring three 8 recovers its deformation, the synchronous belt two 13 is re-tightened, and the power of the drive motor 12 is transmitted to carry out the next stacking and transportation of the plaster packaging.
