Description

Technical Field

[0001] The invention relates to the field of acupuncture needle processing equipment, and in particular to automatic detection and packaging equipment for needle slices. Background Art

[0002] Blister needles refer to a form of packaging for acupuncture needles, and their structure usually includes a transparent (such as PVC material) blister box, which is provided with a needle slot for placing acupuncture needles, and the blister box is sealed with a sealing film (such as aluminum film) to avoid contamination of the acupuncture needles in the blister box.

[0003] The existing needle tablet processing process is generally divided into the processing of blister boxes, the packaging of acupuncture needles, the sealing and molding of needle tablets, and the punching into independent needle tablet products, and then multiple needle tablet products need to be stacked and boxed. Most of the above processing processes in the existing technology are manual operations with a low degree of automation, so there are shortcomings such as low efficiency, low yield rate, and high cost. In addition, multiple different equipment are usually required to complete the whole set of work, and integrated intelligent processing cannot be achieved.

[0004] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a subject to be studied and solved by the present invention. Summary of the invention

[0013] The multi-station detection mechanism includes four groups, wherein the first detection mechanism is a visual detection mechanism, which is arranged at the front end of the heat sealing wheel and above the feeding guide; the camera of the first detection mechanism is arranged downwardly facing the blister box material belt on the feeding guide rail where the acupuncture needles are connected, so as to detect whether there are needles in each needle groove of the blister box material belt;

[0014] The second detection mechanism is a visual detection mechanism, which is arranged at the rear end of the heat sealing wheel. The camera of the second detection mechanism is arranged directly facing the sheet needle material strip after heat sealing, so as to detect whether the sheet needle material strip has product defects;

[0015] The third detection mechanism is arranged corresponding to the punching mechanism, and the photoelectric sensor of the third detection mechanism is arranged directly opposite to the sheet needle material strip at the punching position, so as to detect whether the sheet needle material strip is aligned with the cutter of the punching mechanism;

[0016] The fourth detection mechanism is arranged at the rear end of the punching mechanism, and the photoelectric sensor of the fourth detection mechanism corresponds to the suction cup of a material-taking mechanical arm, and the suction cup is used to suck up each piece needle after punching and place it in a discharge channel; the fourth detection mechanism is used to detect whether the suction cup of the material-taking mechanical arm sucks up the piece needle;

[0017] The automatic plate turning and coding machine includes a sheet needle automatic plate turning mechanism, a material discharging detection and pushing mechanism;

[0018] The automatic plate turning mechanism for sheet needles comprises a plate turning device and an incoming material detection mechanism;

[0020] The incoming material detection mechanism includes a fifth detection mechanism, the photoelectric sensor of which is arranged corresponding to the film needle conveyor belt and is located at the front end of the flap, and is used to collect the film needle arrival information on the film needle conveyor belt;

[0021] The third servo motor and the fifth detection mechanism are both electrically connected to the control system, so that the third servo motor drives the flap to perform intermittent flipping actions corresponding to the position information of the sheet needles, and then flips each of the sheet needles one by one by 180 degrees. After each sheet needle passes through the flipper, they are arranged in an alternating positive and negative manner on the sheet needle conveyor belt;

[0022] The discharging detection and pushing mechanism includes a sixth detection mechanism and a seventh detection mechanism. The photoelectric sensors of both are arranged corresponding to the sheet needles on the sheet needle conveyor belt and are located at the rear end of the flap. Among them, the sixth detection mechanism is used to count the sheet needles, and the seventh detection mechanism is used to detect the positive and negative of the sheet needles;

[0023] The discharging detection and pushing mechanism further includes a stacking chute, a pushing chute, and a horizontal pushing plate;

[0024] The stacking chute is arranged corresponding to the lower part of the rear end of the sheet needle conveyor belt. Each of the sheet needles alternately falls downward into the stacking chute in a state of facing upward and facing downward from the rear end of the sheet needle conveyor belt for stacking;

[0025] The pushing chute is located below the stacking chute. The two are separated by a first baffle, and the first baffle is driven by a first driver to perform opening and closing actions. When the sixth detection mechanism counts to the number of predetermined sheet needles, the first baffle opens, connecting the stacking chute and the pushing chute, so that all the stacked sheet needles fall into the pushing chute.

The feeding channel is correspondingly arranged with the feeding port of the cartoning machine;

[0026] It further includes a second baffle, which is arranged at the bottom of the pushing chute and is driven by a third driver to perform opening and closing actions. When the seventh detection mechanism detects that the sheet needles are not discharged in an alternating positive and negative arrangement, the first baffle opens, connecting the stacking chute and the pushing chute, so that all the misstacked sheet needles fall into the pushing chute. At the same time, the second baffle opens to remove these sheet needles.

[0027] The explanations of the relevant contents in the above technical solutions are as follows:

[0028] 1. In the above solution, the hot pressing device for thermally sealing the blister box tape and the sealing film tape is an electric heating pressing plate or an electric heating pressing wheel.

The needle outlet of the minute hand wheel corresponds to the needle groove in the blister box strip on the feeding guide rail. The minute hand wheel rotates to drop the acupuncture needles in each positioning groove into each needle groove in the blister box strip one by one.

[0032] The rotating shaft of the minute hand wheel is parallel to the rotating shafts of the heat sealing wheel and the feeding wheel, and the rotation speed of the minute hand wheel corresponds to the rotation speed of the feeding wheel.

[0033] 3. In the above solution, the strip needle conveyor belt is a conveyor belt or a conveyor chain, and is driven by a servo motor to perform a horizontal displacement, thereby conveying the strip needles horizontally from front to back.

[0034] 4. In the above solution, the turning plate includes two symmetric sheet-like structures, which are respectively located on both sides of the strip needle conveyor belt in the width direction, so that the turning plate does not interfere with the strip needle conveyor belt.

[0035] 5. In the above solution, it further includes a lower pressing plate, which is arranged above the discharging direction of the pushing slot. When the horizontal pushing plate pushes several strip needles out of the pushing slot, the lower pressing plate presses down on the stacked several strip needles.

[0071] See attached Figures 1 to 11 As shown, an automatic tablet needle detection and packaging device includes a blister-type tablet needle processing machine A, an automatic plate turning and coding machine B, and a cartoning machine C.

[0072] like Figures 1 to 6 As shown, the blister-type tablet needle processing machine A includes a servo synchronous heat sealing mechanism and a multi-station detection mechanism;

[0073] The servo synchronous heat sealing mechanism includes a heat sealing wheel 1 and a feeding wheel 2, wherein the feeding wheel 2 is located at the front end of a horizontal feeding guide rail 3, and the heat sealing wheel 2 is located at the rear end of the feeding guide rail 3. The rotating shafts of the heat sealing wheel 1 and the feeding wheel 2 are both horizontal and arranged along the width direction of the feeding guide rail 3; the blister box material belt 4 is driven by a driving mechanism including the feeding wheel 2 to horizontally move from front to rear on the feeding guide rail 3; the driving mechanism may include a driving wheel, which is arranged at the rear end of the equipment and is used to pull the blister box material belt 4 to move backward.

[0074] The blister box material strip 4 completes the connection of the acupuncture needles while displacing on the feeding guide rail 3, and moves to the heat sealing wheel 1 to combine with a sealing film material strip 5 (which can be an aluminum film), and is heat-sealed by a hot pressing device 7 to become a sheet needle material strip 6. The sheet needle material strip 6 is the blister box material strip 4 sealed by the sealing film material strip 5 and loaded with acupuncture needles in the needle groove.

[0075] Preferably, the heat pressing device 7 is an electric heat pressing plate or an electric heat pressing wheel. After the sealing film material strip 5 is attached to the blister box material strip 4, it passes through the heat sealing wheel 1, and the material strip on the heat sealing wheel 1 is heat-pressed by the heat pressing device 7 to achieve a composite seal of the two, forming a sheet needle material strip 6.

[0076] The heat sealing wheel 1 is provided with a first servo motor 8 on its rotating shaft, and the first servo motor 8 is used to collect the speed pulse signal of the heat sealing wheel 1. That is, the first servo motor 8 acts as an encoder, and the heat sealing wheel 1 can be driven to rotate by a driving motor 9.

[0077] The feeding wheel 2 is driven to rotate by a second servo motor 10. Both the second servo motor 10 and the first servo motor 8 are electrically connected to a control system, such that the second servo motor 10 performs synchronous and constant-speed actions with the drive motor 9 of the heat-sealing wheel 1 according to the rotation speed pulse signal of the heat-sealing wheel 1, thereby driving the feeding wheel 2 to rotate synchronously and at a constant speed with the heat-sealing wheel 1. The specific synchronous control method is prior art and can be proficiently mastered by those skilled in the art. Since it is not the inventive point of this case, it will not be elaborated herein.

[0078] With this design, precise control of the displacement of the blister box tape 4 can be achieved, avoiding excessive influence on the synchronization with the feeding wheel 2 due to too many processing control factors of the heat-sealing wheel 1, and also avoiding the synchronization problem caused by the excessive distance between the feeding wheel 2 and the heat-sealing wheel 1.

[0079] Among them, the blister type acupuncture needle processing machine further includes a blister box tape forming mechanism and an acupuncture needle automatic sorting and dropping mechanism.

[0080] The blister box tape forming mechanism forms a flat raw material tape 11 (such as a PVC tape) into a blister box tape 4 by means of hot pressing. After forming, a plurality of needle grooves are arranged in parallel and at intervals on the blister box tape 4, and each of the needle grooves is used to place an acupuncture needle.

[0081] The blister box tape forming mechanism includes upper and lower heating plates 12 and upper and lower forming dies 13. Since the specific implementation of the blister box tape forming mechanism is prior art and can be proficiently mastered by those skilled in the art, and it is not the inventive point of this case, it will not be elaborated herein.

[0082] The acupuncture needle automatic sorting and dropping mechanism includes a feeding box 14 and a minute hand wheel 15. A number of acupuncture needles are stacked in the feeding box 14 for feeding the minute hand wheel 15; the minute hand wheel 15 is arranged directly above the feeding guide rail 3. A plurality of positioning grooves are evenly distributed in parallel on the circumferential surface of the minute hand wheel 15, and each positioning groove positions an acupuncture needle; the needle outlet of the minute hand wheel 15 corresponds to the needle groove in the blister box tape 4 on the feeding guide rail 3; the minute hand wheel 15 rotates to drop the acupuncture needles in each positioning groove into each needle groove in the blister box tape 4 one by one.

[0083] The rotating shaft of the minute hand wheel 15 is parallel to the rotating shafts of the heat-sealing wheel 1 and the feeding wheel 2, and the rotation speed of the minute hand wheel 15 corresponds to the rotation speed of the feeding wheel 2; specifically, a servo motor can be set to drive the minute hand wheel 15 to rotate, and this servo motor also controls its own rotation speed according to the rotation speed pulse signal of the first servo motor 8 to ensure the matching of the rotation speeds of the heat-sealing wheel 1, the feeding wheel 2, and the minute hand wheel 15, thereby realizing the precise dropping of acupuncture needles into the blister box tape 4.

[0084] The specific implementation scheme of the automatic sorting and dropping mechanism for acupuncture needles is a prior art that can be mastered by those skilled in the art. Since it is not the invention point of this case, it will not be described in detail in this case.

[0085] The multi-station detection mechanism includes four groups, among which the first detection mechanism 17 is a visual detection, which is arranged at the front end of the heat sealing wheel 1 and the rear end of the minute hand wheel 15, and is arranged above the feeding guide 3; the camera of the first detection mechanism 17 is arranged downwardly facing the blister box material belt 4 on the feeding guide 3 where acupuncture needles are connected, so as to detect whether there are needles in each needle groove of the blister box material belt 4, and to check whether there are problems such as missing needles or multiple needles.

[0086] The second detection mechanism 18 is a visual detection mechanism, which is arranged at the rear end of the heat sealing wheel 1 and the front end of the punching mechanism 19. The camera of the second detection mechanism 18 is arranged facing the sheet needle material strip 6 after heat sealing and forming, so as to detect whether there are product defects in the sheet needle material strip 6, such as whether the sealing film is effectively combined with the blister box, whether the sealing film presses the acupuncture needle in the non-needle groove area, whether the sealing film itself is damaged, and other defects.

[0087] The third detection mechanism 20 is arranged corresponding to the punching mechanism 19, and the punching mechanism 19 is used to punch the sheet needle material strip 6 into independent sheet needles 21, and the punching rate of its cutter corresponds to the displacement speed of the sheet needle material strip 6; each sheet needle 21 has a plurality of needle grooves, and an acupuncture needle is positioned in each needle groove. The photoelectric sensor of the third detection mechanism 20 is arranged directly opposite to the sheet needle material strip 6 at the punching position, and is used to detect whether the sheet needle material strip 6 is aligned with the cutter of the punching mechanism 19 to avoid the problem of offset cutting.

[0088] The fourth detection mechanism 22 is arranged at the rear end of the punching mechanism 19. The photoelectric sensor of the fourth detection mechanism 22 is arranged corresponding to the suction cup 24 of a material picking robot arm 23. The suction cup 24 is used to suck up each piece needle 21 after punching one by one and place it in a discharge channel 25; the fourth detection mechanism 22 is used to detect whether the suction cup 24 of the material picking robot arm 23 sucks up the piece needle 21; the specific implementation form and working mode of the material picking robot arm 23 are existing technologies, which can be mastered by technicians in this field. Since it is not the invention point of this case, it will not be repeated in this case.

[0089] like Figures 7 to 10 As shown, the automatic plate turning and coding machine includes a sheet needle automatic plate turning mechanism, a material discharging detection and pushing mechanism.

[0090] The automatic plate turning mechanism for sheet needles comprises a plate turning device and an incoming material detection mechanism;

[0091] The flipper includes a flap 31 and a third servo motor 32. The flap 31 is arranged in the needle conveyor belt 33 with its plate surface corresponding to the displacement direction of the needles 21. The feeding end of the needle conveyor belt 33 is arranged corresponding to the discharging end of the discharging channel 25 in the blister needle processing machine. The third servo motor 32 drives the flap 31 to make a 180-degree flipping motion. The rotating shaft of the flap 31 is horizontal and corresponds to the width direction of the needle conveyor belt 33.

[0092] Among them, the needle conveyor belt 33 is a conveyor belt or a conveyor chain, and is driven by a servo motor 34 to perform a horizontal displacement, so as to convey the needles 21 horizontally from front to back.

[0093] Among them, the flap 31 includes two symmetric sheet-like structures, which are respectively located on both sides of the width direction of the needle conveyor belt 33, so that the flap 31 does not interfere with the displacement of the needle conveyor belt 33.

[0094] Alternatively, an opening can also be provided in the middle of the needle conveyor belt 33, and the flap 31 is rotatably arranged in the opening to avoid the interference of the flap 31 on the needle conveyor belt. (Not shown in the figure)

[0095] The incoming material detection mechanism includes a fifth detection mechanism 35. The photoelectric sensor of the fifth detection mechanism 35 is arranged corresponding to the needle conveyor belt 33 and is located at the front end of the flap 31, and is used to collect the arrival information of the needles 21 on the needle conveyor belt 33. Specifically, the needles 21 can be counted, and an even number or an odd number is used as a signal to trigger the operation of the third servo motor 32.

[0096] The third servo motor 32 and the fifth detection mechanism 35 are both electrically connected to the control system, so that the third servo motor 32 drives the flap 31 to make an intermittent flipping action corresponding to the position information of the needles 21, and then flips each of the needles 21 by 180 degrees one by one, so that each needle 21 is arranged in an alternating positive and negative state on the needle conveyor belt 33 after passing through the flipper, thereby reducing the stacking space of the needles 21, and at the same time, the opposite surfaces of adjacent needles 21 can be of the same material, avoiding the aluminum film from pressing and damaging the PVC blister box.

[0097] The above specific control method is the prior art and can be proficiently mastered by those skilled in the art. Since it is not the invention point of this case, it will not be elaborated in this case.

[0098] The discharging detection and pushing mechanism includes a sixth detection mechanism 36 and a seventh detection mechanism 37. The photoelectric sensors of both are arranged corresponding to the needles 21 on the needle conveyor belt 33 and are located at the rear end of the flap 31.

[0099] Among them, the sixth detection mechanism 36 is used to count the chip pins 21 and detect whether the number of chip pins 21 reaches the preset number for box loading and stacking; the seventh detection mechanism 37 is used to detect the front and back of the chip pins 21 and detect whether the chip pins 21 are alternately arranged in the states of facing up and facing down in sequence.

[0100] The discharging detection and pushing mechanism further includes a stacking groove 38, a pushing groove 39 and a horizontal pushing plate 40.

[0101] The stacking groove 38 is arranged corresponding to the lower part of the rear end of the chip pin conveyor belt 33, and each chip pin 21 alternately falls into the stacking groove 38 in the states of facing up and facing down from the rear end of the chip pin conveyor belt 33 for stacking.

[0102] The pushing groove 39 is located below the stacking groove 38, and the two are separated by a first baffle 41, and the first baffle 41 is driven by a first driver 42 (such as a cylinder or a linear motor) to perform opening and closing actions; when the sixth detection mechanism 36 counts to the predetermined number of chip pins 21 (such as 10 pieces), the control system sends a control signal to the first driver 42 to drive the first baffle 41 to open, connecting the stacking groove 38 and the pushing groove 39, so that all the stacked chip pins 21 fall into the pushing groove 39.

[0103] The horizontal pushing plate 40 is arranged corresponding to the side part of the pushing groove 39 and is driven by a second driver 43 (such as a cylinder or a linear motor) to perform a horizontal displacement, so as to push the chip pins 21 stacked in the pushing groove 39 into a blanking channel 44 as a whole to complete blanking, and the blanking channel 44 is correspondingly arranged with the feeding port of the box loading machine C.

[0104] Preferably, it further includes a lower pressing plate 45, and the lower pressing plate 45 is arranged corresponding to the upper part of the discharging direction of the pushing groove 39. When the horizontal pushing plate 40 pushes several chip pins 21 out of the pushing groove 39, the lower pressing plate 45 (driven by a cylinder or a linear motor) applies pressure downward to the stacked several chip pins 21, so that these chip pins 21 are pressed tightly. This is beneficial to compressing the space occupied by box loading and can also prevent the chip pins 21 from being scattered.

[0105] It further includes a second baffle 46, and the second baffle 46 is arranged at the bottom of the pushing groove 39 and is driven by a third driver 47 (such as a cylinder or a linear motor) to perform opening and closing actions; when the seventh detection mechanism 37 detects that the chip pins 21 are not discharged in an alternating front and back arrangement, the first baffle 41 opens, connecting the stacking groove 38 and the pushing groove 39, so that all the misstacked chip pins 21 fall into the pushing groove 39, and at the same time the second baffle 46 opens to remove these chip pins 21.

[0106] Preferably, a material removing hopper 48 is provided at the bottom of the material pushing groove 39. The second baffle 46 separates the material pushing groove 39 and the material removing hopper 48. The sheet needles 21 enter the material removing hopper 48 to achieve removal.

[0107] The specific implementation forms, working methods and principles of each detection mechanism are all prior arts and can be proficiently mastered by those skilled in the art. Since they are not the inventive points of this case, they will not be elaborated in this case.

[0108] In the above embodiments, since the cartoning machine is a prior art and not the inventive point of this case, the specific structural configuration of the cartoning machine will not be elaborated in this case.

[0109] Compared with the prior art, the advantages of the present invention include:

[0110] First, through the setting of the servo synchronous heat sealing mechanism in the blister type sheet needle processing machine, the feeding wheel can rotate synchronously and at the same speed as the heat sealing wheel, thereby realizing precise control of the displacement of the blister box tape, avoiding excessive influence on the synchronism with the feeding wheel due to too many processing control factors of the heat sealing wheel, and at the same time avoiding the synchronism problem caused by the too far distance between the feeding wheel and the heat sealing wheel;

[0111] Second, through the setting of the multi-station detection mechanism in the blister type sheet needle processing machine, it is ensured that the sheet needles can be effectively monitored in each production link, thereby improving the final qualified product rate;

[0112] Third, through the setting of the sheet needle automatic turning mechanism in the automatic turning and stacking machine, the turning plate can make intermittent turning movements, so that after each sheet needle passes through the turning device, it can be arranged in a positive and negative alternating manner on the sheet needle conveyor belt. This reduces the space for sheet needle discharging and stacking, and at the same time can make the opposite surfaces of adjacent sheet needles be of the same material, avoiding damage to the blister box by the aluminum film;

[0113] Fourth, through the setting of the discharging detection and pushing mechanism in the automatic turning and stacking machine, it can be ensured that the quantity and stacking direction are accurate and error-free when the sheet needles are stacked and discharged, and the discharging can be fast and stable.

[0114] In summary, the present invention has the characteristics of high automation degree, which not only improves the production efficiency, ensures the qualified product rate of the product, but also reduces the labor cost; at the same time, the sheet needles can be processed from the initial raw materials to the final cartoning and discharging through a complete set of equipment, realizing integrated intelligent processing, filling the industry gap, and having outstanding substantive features and remarkable progress.

[0115] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and their purpose is to enable those familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
