Description

Technical Field

[0001] This invention relates to sorting equipment, and more particularly to a blister pack tray sorting machine. Background Technology

[0002] Blister boxes are packaging containers made using a thermoforming process. They have multiple storage slots, each holding a single product. Blister boxes offer excellent transparency, smoothness, and display effect. They have excellent surface decoration properties, allowing for printing and metal finishing. They possess good mechanical strength, good barrier properties against oxygen and water vapor, good chemical resistance, are non-toxic, and have reliable hygiene properties. They are widely used for packaging food, pharmaceuticals, and medical devices, and can even be sterilized with gamma rays.

[0003] When using blister packs to package products, the process typically involves manually placing the blister packs on a workbench, sorting the products into the blister packs, sealing the blister packs with heat-sealing equipment, and then manually packing the blister packs into boxes. Removing the products also requires manually tearing off the film from the blister packs. This repeated manual handling of the products can easily lead to dust, fingerprints, and other defects during transit. Furthermore, the manual sorting, sealing, and stacking of products is inefficient, involves numerous steps, and requires a significant investment of manpower, resulting in extremely high labor costs and negative impacts on the product's performance. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides a blister box sorting machine that can automatically place blister boxes and automatically sort products.

[0005] The technical problem to be solved by the present invention is achieved through the following technical solution:

[0006] A blister pack sorting machine includes a frame and components mounted on the frame.

[0007] A box supply mechanism is used to supply blister boxes;

[0008] The feeding mechanism is used to supply products;

[0009] A box-supporting mechanism, used to support the blister box, is disposed between the feeding mechanism and the box-supplying mechanism;

[0010] A sorting and placement mechanism is used to sort and place the blister boxes and products between the box feeding mechanism, the material feeding mechanism and the box tray mechanism, and is located above the box feeding mechanism, the material feeding mechanism and the box tray mechanism;

[0011] The placement and sorting mechanism includes a placement suction cup group, a sorting suction cup group, and a suction cup moving device. The suction cup moving device connects and drives the placement suction cup group and the sorting suction cup group to move between the feeding mechanism, the box feeding mechanism, and the box holding mechanism. When the placement suction cup group moves to the box feeding mechanism, it picks up the blister boxes in the box feeding mechanism, and when it moves to the box holding mechanism, it places the picked-up blister boxes on the box holding mechanism. When the sorting suction cup group moves to the feeding mechanism, it picks up the products in the feeding mechanism, and when it moves to the box holding mechanism, it sorts the picked-up products into the blister boxes.

[0012] Furthermore, the box supply mechanism includes a box storage device and a box retrieval device arranged opposite to each other, the box storage device being located above the placement and sorting mechanism, and the box retrieval device being located below the placement and sorting mechanism;

[0013] The box compartment device is used to stack the blister boxes. It has a box outlet at its lower end and includes multiple box compartment side panels and multiple box compartment support plates. The multiple box compartment side panels are vertically arranged on the periphery of the box outlet to form a stacking space for the blister boxes. The multiple box compartment support plates are horizontally arranged on the periphery of the box outlet to support the outer sidewalls of the blister boxes.

[0014] The box-retrieving device is used to remove the blister boxes stacked in the box compartment device from the box outlet, and includes multiple box-retrieving grippers and a gripper motion device that connects and drives the multiple box-retrieving grippers to move relative to the box supply mechanism.

[0015] The box-retrieving gripper includes a fixed gripper, a movable gripper, and a gripper driver. The fixed gripper and the movable gripper are arranged opposite each other along a first direction or a second direction. The gripper driver drives the movable gripper to move relative to the fixed gripper. When the movable gripper moves away from the fixed gripper and the gripper movement device drives the multiple box-retrieving grippers to rise and approach the box compartment device, the fixed gripper and the movable gripper move to the inner and outer sides of the outer perimeter of the blister box located at the box outlet. When the movable gripper moves closer to the fixed gripper and the gripper movement device drives the multiple box-retrieving grippers to descend and move away from the box compartment device, the movable gripper pushes the outer perimeter of the bottom blister box inward to the outside of the box compartment tray and cooperates with the fixed gripper to clamp the outer perimeter of the blister box, so as to remove the blister box from the box outlet of the box compartment device.

[0016] Furthermore, the gripper motion device includes a first mounting base and a gripper lifting driver. The plurality of box-retrieving grippers are disposed on the periphery of the first mounting base and correspond to the outer sidewall of the blister box. The gripper lifting driver is used to drive the first mounting base to lift and lower, thereby driving the plurality of box-retrieving grippers to lift and lower.

[0017] Furthermore, the gripper motion device also includes a gripper revolution driver, which is connected between the first mounting base and the gripper lifting driver, and is used to drive the first mounting base to rotate, thereby causing the multiple box-retrieving grippers to revolve around the vertical axis.

[0018] Furthermore, the fixed clamp includes an extending portion and a clamping portion connected vertically. The movable clamp extends outward from the side facing the fixed clamp to form a protrusion, which corresponds to the clamping portion. When the gripper movement device drives the multiple box-retrieving grippers to rise and approach the box storage device, the extending portion extends into the space between the outer side wall of the blister box and the storage slot. When the clamp driver drives the movable clamp to move closer to the fixed clamp, the protrusion pushes the outer side wall of the bottom blister box towards the clamping portion and cooperates with the clamping portion to clamp the outer side wall of the bottom blister box.

[0019] Furthermore, the upper end of the extension portion facing the movable clamp has an inclined surface, so that the width of the extension portion gradually increases from top to bottom.

[0020] Furthermore, the blister box sorting machine also includes components mounted on the frame.

[0021] A film supply mechanism, used to provide a protective diaphragm, is disposed above the placement and sorting mechanism;

[0022] A film-taking mechanism is used to take and place the protective diaphragm between the film-supplying mechanism and the tray mechanism, and is disposed above the film-supplying mechanism;

[0023] The film-retrieving mechanism includes multiple film-retrieving telescopic needles and a needle movement device that connects and drives the multiple film-retrieving telescopic needles to move between the film supply mechanism and the tray mechanism. The multiple film-retrieving telescopic needles are arranged to cross each other and tilt downwards. When the multiple film-retrieving telescopic needles move above the film supply mechanism, they extend and insert to grab the protective diaphragm in the film supply mechanism. When they move above the tray mechanism, they retract and pull out to place the grabbed protective diaphragm on the blister box.

[0024] Furthermore, the blister box sorting machine also includes components mounted on the frame.

[0025] A box-supporting mechanism, used to support the packaging box, is located below the box-supporting mechanism;

[0026] The tray mechanism includes two rotating trays that can be opened and closed relative to each other, and an opening and closing drive device that drives the two rotating trays to open and close relative to each other. When the two rotating trays are open relative to each other, the blister box is allowed to pass through and enter the packaging box on the tray mechanism. When the two rotating trays are closed relative to each other, the blister box is held in place.

[0027] Furthermore, the film-retrieving mechanism is also used to retrieve and place the protective diaphragm and the blister box between the tray mechanism and the box mechanism;

[0028] The plurality of film-grabbing telescopic needles retract and extend when they move to a first height above the tray mechanism to stack the gripped protective diaphragm on the blister pack. When they move to a second height above the tray mechanism, they extend and insert to simultaneously grip the stacked protective diaphragm and the blister pack. When they move into the packaging box on the tray mechanism, they retract and extend to simultaneously place the gripped protective diaphragm and the blister pack into the packaging box. The distance between the film-grabbing telescopic needles at the first height and the tray mechanism is greater than the distance between them at the second height.

[0029] Furthermore, the tray mechanism includes a support platform and a platform lifting device that drives the support platform to move up and down. When the opening and closing drive device drives the two rotating trays to open relative to each other, the platform lifting device drives the support platform to rise and approach the tray mechanism. When the platform lifting device drives the support platform to descend and move away from the tray mechanism, the opening and closing drive device drives the two rotating trays to close relative to each other.

[0030] The present invention has the following beneficial effects: The present invention automatically provides the blister box and the product to the placement and sorting mechanism through the box feeding mechanism and the feeding mechanism, respectively. Then, the placement and sorting mechanism automatically places the blister box on the tray mechanism and automatically sorts the product into the blister box. This realizes the automatic placement of the blister box and the automatic sorting of the product, which greatly improves production efficiency, saves labor costs, and reduces human contact with the product, avoiding problems such as dust and fingerprints on the product.

[0046] like Figure 1 and 2 As shown, a blister pack sorting machine includes a frame 100 and components mounted on the frame 100.

[0047] Box supply mechanism 200, used to supply blister box a;

[0048] The feeding mechanism 300 is used to provide product b;

[0049] The box support mechanism 400 is used to support the blister box a and is disposed between the feeding mechanism 300 and the box supply mechanism 200;

[0050] A sorting and placement mechanism 500 is used to sort and place the blister box a and product b between the box feeding mechanism 200, the feeding mechanism 300 and the tray mechanism 400, and is located above the box feeding mechanism 200, the feeding mechanism 300 and the tray mechanism 400.

[0051] The placement and sorting mechanism 500 includes a placement suction cup group 510, a sorting suction cup group 520, and a suction cup moving device 530. The suction cup moving device 530 connects and drives the placement suction cup group 510 and the sorting suction cup group 520 to move between the feeding mechanism 300, the box feeding mechanism 200, and the box holding mechanism 400. When the placement suction cup group 510 moves to the box feeding mechanism 200, it picks up the blister box a inside the box feeding mechanism 200, and when it moves to the box holding mechanism 400, it places the picked-up blister box a onto the box holding mechanism 400. When the sorting suction cup group 520 moves to the feeding mechanism 300, it picks up the product b inside the feeding mechanism 300, and when it moves to the box holding mechanism 400, it sorts the picked-up product b into the blister box a.

[0052] This invention automatically provides the blister box a and product b to the placement and sorting mechanism 500 via the box supply mechanism 200 and the feeding mechanism 300, respectively. Then, the placement and sorting mechanism 500 automatically places the blister box a on the tray mechanism 400 and automatically sorts the product b into the blister box a. This realizes the automatic placement of the blister box a and the automatic sorting of the product b, which greatly improves production efficiency, saves labor costs, and reduces human contact with the product b, avoiding problems such as dust and fingerprints on the product b.

[0053] The suction cup moving device 530 includes a first suction cup moving device 531, a first suction cup lifting device 532, a second suction cup moving device 533, and a second suction cup lifting device 534. The first suction cup moving device 531 is used to drive the placement suction cup group 510 and the sorting suction cup group 520 to move along a first direction. The first suction cup lifting device 532 is used to drive the placement suction cup group 510 to move up and down, and is disposed between the first suction cup moving device 531 and the placement suction cup group 510. The second suction cup moving device 533 is used to drive the sorting suction cup group 520 to move along a second direction, and is disposed between the first suction cup moving device 531 and the second suction cup lifting device 534. The second suction cup lifting device 534 is used to drive the sorting suction cup group 520 to move up and down, and is disposed between the second suction cup moving device 533 and the sorting suction cup group 520.

[0054] In this embodiment, the first direction is perpendicular to the second direction, and both the first and second directions are located on a horizontal plane.

[0055] The feeding mechanism 300 and the box feeding mechanism 200 are respectively disposed on opposite ends of the box tray mechanism 400 along the first direction; the working steps of the blister box sorting machine are as follows:

[0056] The first suction cup moving device 531 drives the placement suction cup group 510 and the sorting suction cup group 520 to move along the first direction to the box supply mechanism 200. The first suction cup lifting device 532 drives the placement suction cup group 510 to descend. The placement suction cup group 510 picks up the blister box a in the box supply mechanism 200. The first suction cup lifting device 532 drives the placement suction cup group 510 to rise and reset.

[0057] The first suction cup moving device 531 drives the placement suction cup group 510 and the sorting suction cup group 520 to move along the first direction to the tray mechanism 400. The first suction cup lifting device 532 drives the placement suction cup group 510 to descend. The placement suction cup group 510 places the suctioned blister box a onto the tray mechanism 400. The first suction cup lifting device 532 drives the placement suction cup group 510 to rise and reset.

[0058] The first suction cup moving device 531 drives the placement suction cup group 510 and the sorting suction cup group 520 to move along the first direction to the feeding mechanism 300. The second suction cup lifting device 534 drives the sorting suction cup group 520 to descend. The sorting suction cup group 520 picks up the product b in the feeding mechanism 300. The second suction cup lifting device 534 drives the sorting suction cup group 520 to rise and reset.

[0059] The first suction cup moving device 531 drives the placement suction cup group 510 and the sorting suction cup group 520 to move along the first direction to the tray mechanism 400. The first suction cup moving device 531 and the second suction cup moving device 533 cooperate to drive the sorting suction cup group 520 to move along the first direction and the second direction respectively, so as to position the product b on the corresponding storage slot of the blister box a. The second suction cup lifting device 534 drives the sorting suction cup group 520 to descend. The sorting suction cup group 520 sorts the product b into the corresponding storage slot of the blister box a. The second suction cup lifting device 534 drives the sorting suction cup group 520 to rise and reset. The first suction cup moving device 531 and the second suction cup moving device 533 cooperate to drive the sorting suction cup group 520 to move and reset along the first direction and the second direction respectively.

[0060] The automatic placement suction cup group 510 and the sorting suction cup group 520 of the present invention share the first suction cup moving device 531 in the first direction, which can reduce the number of moving devices and reduce equipment cost and volume.

[0061] The blister box a has multiple storage slots, which are distributed in M ​​rows and N columns along the first and second directions, respectively, where M and N ≥ 2. Both the product b and the storage slots have length and width directions, with the length dimension being greater than the width dimension, and the length and width directions corresponding to each other. The length direction of the product b in the feeding mechanism 300 is parallel to the first direction, and the length direction of the storage slots of the blister box a on the tray mechanism 400 is parallel to the second direction. The suction cup movement device 530 also includes a suction cup rotation device 535, used to drive the sorting suction cup group 520 to rotate around the vertical axis to adjust the length direction of the product b, and is positioned between the second suction cup lifting device 534 and the sorting suction cup group 520.

[0062] During the process of the first suction cup moving device 531 driving the placement suction cup group 510 and the sorting suction cup group 520 from the feeding mechanism 300 to the tray mechanism 400, the suction cup rotation device 535 drives the sorting suction cup group 520 to rotate, so as to adjust the length direction of the product b from the first direction to the second direction.

[0063] The placement suction cup group 510 includes multiple placement suction cups, which are distributed on the periphery of the sorting suction cup group 520 and correspond to the top periphery of the blister box a; the first suction cup lifting device 532 includes multiple first lifting drivers, and the placement suction cups are connected to the first lifting drivers in a one-to-one correspondence.

[0064] In this embodiment, there are two tray mechanisms 400, which are arranged side by side along the first direction between the feeding mechanism 200 and the loading mechanism 300. The sorting suction cup assembly 520 includes two sorting suction cups, which are symmetrically arranged between each other, and each sorting suction cup grabs one product b. During operation, each of the two sorting suction cups grabs one product b in the loading mechanism 300, and then sorts the grabbed products b into the corresponding storage slots of the blister boxes a of the two tray mechanisms 400 in sequence.

[0065] In this embodiment, the second suction cup lifting device 534 includes two second lifting drivers, and the suction cup rotation device 535 includes two suction cup rotation drivers. The sorting suction cup, the second lifting drivers, and the suction cup rotation drivers are connected in a one-to-one correspondence.

[0066] like Figure 3 As shown, the feeding mechanism 300 includes a feeding conveyor belt 310 and a feeding sensor (not shown in the figure). One end of the feeding conveyor belt 310 faces the tray mechanism 400. The feeding sensor is disposed on the end of the feeding conveyor belt 310 facing the tray mechanism 400 and is used to sense whether the product b is on the end of the feeding conveyor belt 310 facing the tray mechanism 400. When the feeding conveyor belt 310 conveys the product b from its other end to its end facing the tray mechanism 400, the feeding sensor is triggered and controls the feeding conveyor belt 310 to pause conveying to wait for the sorting suction cup group 520 to remove the product b. After the product b is removed, the feeding sensor resets and controls the feeding conveyor belt 310 to continue conveying.

[0067] The feeding conveyor belt 310 is provided with a first limiting element 311 and a second limiting element 312 arranged in parallel along a second direction. A conveying channel 313 for the product b along a first direction is formed between the first limiting element 311 and the second limiting element 312. The width of the conveying channel 313 is adapted to the width of the product b so that the length direction of the product b on the feeding conveyor belt 310 is parallel to the first direction.

[0068] In this embodiment, the first limiting element 311 and the second limiting element 312 are a first limiting belt and a second limiting belt that are sleeved side by side outside the feeding conveyor belt 310.

[0069] like Figure 4-7 As shown, the box feeding mechanism 200 includes a box storage device 210 and a box retrieval device 220 arranged opposite to each other. The box storage device 210 is located above the placement and sorting mechanism 500 (the track interval area of ​​the first suction cup moving device 531), and the box retrieval device 220 is located below the placement and sorting mechanism 500 (the track interval area of ​​the first suction cup moving device 531).

[0070] The box compartment device 210 is used to stack the blister box a, and its lower end is provided with a box outlet, such as... Figure 7 As shown, it includes multiple box compartment side panels 211 and multiple box compartment trays 212. The multiple box compartment side panels 211 are vertically arranged on the periphery of the box outlet to form a stacking space for the blister box a. The multiple box compartment trays 212 are horizontally arranged on the periphery of the box outlet to support the outer side wall a1 of the blister box a.

[0071] The box-removing device 220 is used to remove the blister box a stacked in the box storage device 210 from the box outlet, and includes multiple box-removing grippers 221 and a gripper motion device 222 connected to drive the multiple box-removing grippers 221 to move relative to the box supply mechanism 200.

[0072] like Figure 6 As shown, the box-retrieving gripper 221 includes a fixed gripper 2211, a movable gripper 2212, and a gripper driver 2213. The fixed gripper 2211 and the movable gripper 2212 are arranged opposite each other along a first direction or a second direction. The gripper driver 2213 drives the movable gripper 2212 to move relative to the fixed gripper 2211. When the movable gripper 2212 moves away from the fixed gripper 2211 and the gripper motion device 222 drives the plurality of box-retrieving grippers 221 to rise and approach the box compartment device 210, the fixed gripper 2211 and the movable gripper 2212 move away from the fixed gripper 2211 and the movable gripper 2212 move relative to the fixed gripper 2211. The movable gripper 2212 moves to the inside and outside of the outer side wall a1 of the blister box a located at the box outlet; when the movable gripper 2212 moves closer to the fixed gripper 2211 and the gripper movement device 222 drives the multiple box-removing grippers 221 to descend away from the box compartment device 210, the movable gripper 2212 pushes the outer side wall a1 of the bottom blister box a inward to the outside of the box compartment tray 212, and cooperates with the fixed gripper 2211 to clamp the outer side wall a1 of the blister box a, so as to remove the blister box a from the box outlet of the box compartment device 210.

[0073] When multiple blister packs a are stacked in the box storage device 210, between two adjacent blister packs a, the upper blister pack a is nested on the lower blister pack a, and the outer side wall a1 of the upper blister pack a is in contact with the outer side wall a1 of the lower blister pack a, forming a frictional force between them. When the bottom blister pack a is removed, the bottom blister pack a has a downward frictional force on the blister pack a above it. This invention uses a box tray 212 at the box outlet of the box tray device 210 to support stacked blister boxes a. When the box retrieval device 220 removes the bottom blister box a, the movable clamp 2212 pushes the outer side wall a1 of the bottom blister box a towards the fixed clamp 2211, and cooperates with the fixed clamp 2211 to clamp the outer side wall a1 of the bottom blister box a. At the same time, it pushes the outer side wall a1 of the bottom blister box a outside the box tray 212, so that the removal of the bottom blister box a is not affected by the box tray 212. Moreover, the box tray 212 still supports the outer side wall a1 of the previous blister box a, so that the previous blister box a will not be taken away with it due to the friction of the bottom blister box a.

[0074] The working steps of the box-retrieving device 220 are as follows:

[0075] The gripper motion device 222 drives the multiple box-retrieving grippers 221 to rise and approach the box compartment device 210, so that the fixed clamp 2211 and the movable clamp 2212 move to the outer side wall a1 of the bottom blister box a respectively;

[0076] The clamp driver 2213 drives the movable clamp 2212 to move closer to the fixed clamp 2211, so that the movable clamp 2212 pushes the outer side wall a1 of the bottom blister box a towards the fixed clamp 2211, and cooperates with the fixed clamp 2211 to clamp the outer side wall a1 of the bottom blister box a.

[0077] The gripper motion device 222 drives the multiple box-retrieving grippers 221 to descend away from the box storage device 210, so that the fixed clamp 2211 and the movable clamp 2212 can remove the clamped blister box a from the box outlet of the box storage device 210.

[0078] The chuck driver 2213 drives the movable chuck 2212 to move away from the fixed chuck 2211, so that the fixed chuck 2211 and the movable chuck 2212 cooperate to loosen the outer sidewall a1 of the blister box a, and wait for the placement and sorting mechanism 500 to take away the blister box a.

[0079] like Figure 5As shown, the gripper motion device 222 includes a first mounting base 2221, a gripper revolution driver 2222, and a gripper lifting driver 2223. The plurality of box-retrieving grippers 221 are disposed on the periphery of the first mounting base 2221 and correspond to the outer sidewall a1 of the blister box a. The gripper revolution driver 2222 is used to drive the first mounting base 2221 to rotate, thereby causing the plurality of box-retrieving grippers 221 to revolve around the vertical axis. The gripper lifting driver 2223 is used to drive the first mounting base 2221 to lift, thereby causing the plurality of box-retrieving grippers 221 to lift. The gripper revolution driver 2222 is connected between the first mounting base 2221 and the gripper lifting driver 2223.

[0080] The gripper revolution driver 2222 drives multiple box-retrieving grippers 221 located on the periphery of the first mounting base 2221 to revolve around the vertical axis, thereby adjusting the relative angle between the multiple box-retrieving grippers 221 and the blister box a in the box compartment device 210, so that the multiple box-retrieving grippers 221 can be aligned with the outer sidewall a1 of the blister box a.

[0081] The fixed clamp 2211 includes an extension portion 2214 and a clamping portion 2215 connected vertically. The upper end of the extension portion 2214 facing the movable clamp 2212 has an inclined surface, so that the width of the extension portion 2214 gradually increases from top to bottom, so as to facilitate insertion between the outer side wall a1 of the blister box a and the storage groove. The movable clamp 2212 extends outward from the side facing the fixed clamp 2211 to form a protrusion 2216, which corresponds to the clamping portion 2215. When the gripper motion device 222 drives the plurality of box-retrieving grippers 221 to rise and approach the box storage device 210, the extension part 2214 extends into the space between the outer side wall a1 of the blister box a and the storage slot; when the clamp driver 2213 drives the movable clamp 2212 to move closer to the fixed clamp 2211, the protrusion 2216 pushes the outer side wall a1 of the bottom blister box a towards the clamping part 2215, and cooperates with the clamping part 2215 to clamp the outer side wall a1 of the bottom blister box a.

[0082] like Figure 7 As shown, the box compartment device 210 also includes a plurality of tray drivers 213, one tray driver 213 corresponding to one box compartment tray 212. The tray driver 213 drives the box compartment tray 212 to move relative to the box outlet. When the box compartment tray 212 moves closer to the box outlet, it supports the outer side wall a1 of the blister box a, and when it moves away from the box outlet, the outer side wall a1 of the blister box a is released.

[0083] After the tray driver 213 drives the box tray 212 to move away from the box outlet, the remaining blister boxes a can be easily removed manually from the tray outlet.

[0084] The positions of the multiple box compartment trays 212 and the multiple box-retrieving claws 221 are one-to-one; the box compartment trays 212 are provided with slots 214. When the claw movement device 222 drives the multiple box-retrieving claws 221 to rise, the fixed clamps 2211 and movable clamps 2212 of each box-retrieving claw 221 pass through the slots 214 of the corresponding box compartment trays 212, and then move to the outer side wall a1 of the bottom blister box a respectively.

[0085] As an optimization of Embodiment 1, in this embodiment, such as Figure 1 and 8 As shown, the blister pack sorting machine also includes components mounted on the frame 100.

[0086] A film supply mechanism 600 is used to provide a protective diaphragm d and is disposed above the placement and sorting mechanism 500;

[0087] A film-taking mechanism 700 is used to take and place the protective diaphragm d between the film-supplying mechanism 600 and the tray mechanism 400, and is disposed above the film-supplying mechanism 600;

[0088] Among them, such as Figure 9 As shown, the film-taking mechanism 700 includes a plurality of film-taking telescopic needles 710 and a needle movement device 720 that connects and drives the plurality of film-taking telescopic needles 710 to move between the film supply mechanism 600 and the tray mechanism 400. The plurality of film-taking telescopic needles 710 are arranged to cross each other and tilt downwards. When the plurality of film-taking telescopic needles 710 move above the film supply mechanism 600, they extend and insert to grab the protective diaphragm d inside the film supply mechanism 600. When they move above the tray mechanism 400, they retract and pull out to stack the grabbed protective diaphragm d on the blister box a.

[0089] like Figure 10 As shown, the film supply mechanism 600 includes a film supply roll 610, a film pulling device 620, and a film cutting device 630.

[0090] The film supply roll 610 is used to wind the diaphragm material strip d1;

It includes a plurality of film-pulling grippers 621 and a film-pulling motion device 622 that connects and drives the plurality of film-pulling grippers 621 to move relative to the film supply roll 610. When the plurality of film-pulling grippers 621 move closer to the film supply roll 610, they grab the diaphragm material strip d1 on the film supply roll 610. When they move away from the film supply roll 610, they pull the grabbed diaphragm material strip d1 out of the film supply roll 610.

[0092] The film cutting device 630 is used to cut the diaphragm material strip d1 pulled out by the film pulling device 620 to form the protective diaphragm d. It is disposed between the film supply roll 610 and the film pulling device 620, and includes a diaphragm cutter 631 and a film cutting drive device 632 connected to drive the diaphragm cutter 631 to cut the diaphragm material strip d1.

[0093] The working steps of the film supply mechanism 600 and the film dispensing mechanism 700 are as follows:

[0094] The needle movement device 720 drives the plurality of film-taking telescopic needles 710 to rise above the film supply mechanism 600;

[0095] The film-pulling motion device 622 drives the plurality of film-pulling grippers 621 to move from the side of the film-taking mechanism 700 away from the film-supply roll 610 along the first direction to the side away from the film-supply roll 610, so as to move closer to the film-supply roll 610.

[0096] The plurality of film-pulling grippers 621 grasp the diaphragm material strip d1 on the film supply roll 610;

[0097] The film-pulling motion device 622 drives the plurality of film-pulling grippers 621 to move from the side of the film-taking mechanism 700 toward the film-supply roll 610 along the first direction to the side away from the film-supply roll 610, so as to move away from the film-supply roll 610 and cause the plurality of film-pulling grippers 621 to pull the gripped diaphragm strip d1 from the film-supply roll 610;

[0098] The plurality of membrane-grabbing telescopic needles 710 extend and insert to grab the pulled-out diaphragm strip d1;

[0099] The film cutting drive device 632 drives the film supply cutter 631 to cut the diaphragm material strip d1 pulled out by the plurality of film pulling claws 621 to form the protective diaphragm d;

[0100] The needle movement device 720 drives the plurality of film-taking telescopic needles 710 to descend above the film supply mechanism 600;

[0101] The plurality of film-grabbing telescopic needles 710 retract and extend to place the gripped protective diaphragm d onto the blister box a.

[0102] like Figure 9 As shown, the needle movement device 720 includes a second mounting base 721 and a needle lifting device 722. The needle lifting device 722 is used to connect and drive the second mounting base 721 to lift. The plurality of film-taking telescopic needles 710 are disposed on the periphery of the second mounting base 721, corresponding to the periphery of the protective diaphragm d.

[0103] In this embodiment, the needle movement device 720 further includes a needle moving device 723, which is used to drive the second mounting base 721 to move along the first direction between the two tray mechanisms 400. It is connected between the second mounting base 721 and the needle lifting device 722 to place the protective diaphragm d on the two blister boxes a respectively.

[0104] The film-taking telescopic needle 710 includes a needle baffle 711, a needle 712 disposed on the needle baffle 711, and a telescopic driver 713. The needle baffle 711 has a front stop 714 in front of the needle 712, and the front stop 714 has a needle hole for the needle 712 to pass through. The telescopic driver 713 drives the needle 712 to move axially so that the needle 712 can extend and retract inside and outside the needle hole of the front stop 714. When all the needles 712 of the plurality of film-taking telescopic needles 710 are extended, the coverage area of ​​each needle 712 on the horizontal plane increases. At this time, the inclined needles 712 support the protective diaphragm d being grasped to prevent the protective diaphragm d from falling off. When all the needles 712 of the plurality of film-taking telescopic needles 710 are retracted, the coverage area of ​​each needle 712 on the horizontal plane decreases. At this time, the front stop 714 is used to press against the protective diaphragm d so that each needle 712 is pulled out from the protective diaphragm d. Example 3

[0105] As an optimization of Embodiment 2, in this embodiment, such as Figure 1 and 11 As shown, the blister pack sorting machine also includes components mounted on the frame 100.

[0106] The box support mechanism 800 is used to support the packaging box c and is located below the box support mechanism 400;

[0107] The tray mechanism 400 includes two rotating trays 410 that can be opened and closed relative to each other, and an opening and closing drive device 420 connected to drive the two rotating trays 410 to open and close relative to each other. When the two rotating trays 410 are open relative to each other, the blister box a is allowed to pass through and enter the packaging box c on the tray mechanism 800. When the two rotating trays 410 are closed relative to each other, the blister box a is held in place.

[0108] After the blister box a is filled with the product b, the opening and closing drive device 420 drives the two rotating trays 410 to open relative to each other, allowing the blister box a to pass through and enter the packaging box c on the tray mechanism 800. After the packaging box c is filled with the blister box a, the packaging box c on the tray mechanism 800 is then manually replaced.

[0109] In this embodiment, there are two tray baffles 410, which are arranged opposite to each other along the first direction. The side of the two baffles that are far apart from each other is rotatably connected to the frame 100. The opening and closing drive device 420 drives the two tray baffles 410 to rotate so as to achieve relative opening and closing.

[0110] In this embodiment, there are two tray mechanisms 800, which are respectively disposed below the two tray mechanisms 400.

[0111] To prevent the protective film d on the blister box a from shifting when it enters the packaging box c on the tray mechanism 800 via the tray mechanism 400, preferably, the film-retrieving mechanism 700 is also used to retrieve and place the protective film d and the blister box a between the tray mechanism 400 and the tray mechanism 800.

[0112] The plurality of film-grabbing telescopic needles 710 retract and extend when they move to a first height above the tray mechanism 400 to stack the grasped protective diaphragm d on the blister box a. When they move to a second height above the tray mechanism 400, they extend and insert to simultaneously grasp the stacked protective diaphragm d and the blister box a. When they move into the packaging box c on the box mechanism 800, they retract and extend to simultaneously place the grasped protective diaphragm d and the blister box a into the packaging box c. The distance between the film-grabbing telescopic needles 710 at the first height and the tray mechanism 400 is greater than the distance between them at the second height.

[0113] The pallet mechanism 800 includes a support platform 810 and a platform lifting device 820 that drives the support platform 810 to rise and fall. When the opening and closing drive device 420 drives the two rotating pallets 410 to open relative to each other, the platform lifting device 820 drives the support platform to rise and approach the pallet mechanism 400 to shorten the packing distance of the blister box a. When the platform lifting device 820 drives the support platform to fall away from the pallet mechanism 400, the opening and closing drive device 420 drives the two rotating pallets 410 to close relative to each other to avoid the packaging box c interfering with the closing of the pallets 410.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and not to limit them. Although the embodiments of the present invention have been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the embodiments of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
