Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical production equipment, specifically relating to a material suction and discharge device for a material feeding and discharging system of a tray feeding machine. Background Technology

[0002] In the pharmaceutical packaging production process, after the tray forming and sealing machine completes the forming and sealing of the blister packs, the blister packs need to be transferred to the next process. This transfer process faces two key technical challenges: First, due to the structural differences of the equipment at each station of the production line, there is a height difference of 100-300mm between the pick-up and placement positions of the blister packs. If a traditional transfer device uses a small-stroke cylinder, although it can accurately control the downward pressure during adsorption to avoid damaging the aluminum foil sealing layer on the surface of the blister pack, the insufficient stroke during transfer to the downstream station causes the blister pack to fail to reach the designated height and has to be released from a higher position, resulting in a falling impact. Second, if a large-stroke cylinder is used, although it can cover the entire transfer stroke, the extension of the cylinder needs to be precisely controlled during the adsorption stage. Slight carelessness can lead to excessive downward pressure, causing deformation of the blister pack or damage to the drug. During the release stage, it is necessary to prevent the cylinder from continuing to extend and causing secondary compression. This dilemma makes it difficult for existing transfer devices to ensure the integrity of the blister packs while failing to meet the requirements of modern production lines for transfer efficiency and precision.

[0003] Especially when handling blister packs with precision aluminum foil packaging, it is necessary to ensure that the aluminum foil is not damaged during the transfer process and that the blister pack is accurately placed in the target position. This places extremely high technical requirements on the transfer device. Therefore, the traditional single-stage telescopic mechanism used in the existing technology has the problem that it is difficult to simultaneously achieve stroke control accuracy and transfer height difference adjustment during the adsorption and transfer of the blister pack, which can easily cause damage to the aluminum foil of the blister pack. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a suction and discharge device for a tray feeding and discharging system, which solves the problem that the traditional single-stage telescopic mechanism used in the prior art has difficulty in simultaneously ensuring stroke control accuracy and adjusting the transfer height difference during the adsorption and transfer of medicine trays, and is prone to causing damage to the aluminum film of the medicine trays.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A suction and discharge device for a tray feeding and discharging system of a tray feeding machine is used to absorb and transfer the medicine plate on the first working surface of the tray feeding end to the second working surface.

[0007] A drive assembly is provided above the first working surface. The drive assembly includes a slider and a drive unit. The drive unit is used to drive the slider to move horizontally from directly above the first working surface to directly above the second working surface.

[0008] An adsorption section for adsorbing the medicine plate is provided below the slider;

[0009] The slider and the adsorption part are connected by a telescopic component. The telescopic component is used to drive the adsorption part to move vertically downward in two stages. When one stage is in a fully contracted state and the other stage is in a fully extended state, the lower end of the adsorption part is in contact with the upper end surface of the medicine plate on the first working surface.

[0010] The telescopic assembly includes a first telescopic part placed vertically downwards, which is vertically fixed to the slider. A first mounting plate is fixed to the output end of the first telescopic part. A second telescopic part placed vertically downwards is fixed to the first mounting plate. A second mounting plate is fixed to the output end of the second telescopic part. An adsorption part is installed below the second mounting plate.

[0011] The drive assembly also includes a horizontally placed slide rail, on which the slider is slidably connected.

[0012] The adsorption unit includes a horizontally placed connecting strip, which is fixed to the lower end of the second mounting plate. Multiple vacuum suction cups are provided at the lower end of the connecting strip, and the multiple vacuum suction cups are arranged along the axial direction of the connecting strip.

[0013] The connecting strips are multiple strips placed side by side.

[0014] Each connecting strip has an air cavity, and one end of the vacuum suction cup is connected to the corresponding air cavity in the connecting strip.

[0015] The adsorption unit also includes multiple branch pipes, with the number of branch pipes and connecting strips being equal and corresponding one-to-one. Each branch pipe is connected to the air cavity in the corresponding connecting strip. The other end of the multiple branch pipes is connected to an air pipe, and the other end of the air pipe is used to connect to a negative pressure source.

[0016] Both the first telescopic part and the second telescopic part can be any one of a pneumatic cylinder, an electric push rod, or a hydraulic cylinder.

[0017] The beneficial effects of this utility model are:

[0018] This application achieves precise control of the blister pack transfer process by setting up a telescopic component with two-stage telescopic movement function, in conjunction with a horizontal drive component. When one stage of the telescopic component is fully extended while the other stage remains retracted, the adsorption part can accurately adhere to the upper surface of the blister pack without excessive pressure, avoiding damage to the aluminum film sealing structure. After being transferred to the second working surface, the height of the blister pack is gradually reduced by the extension of the other stage of the telescopic component, so that the blister pack is released only when it is close to the second working surface, effectively preventing falling impact caused by excessive height difference. This two-stage alternating telescopic working mode not only ensures the reliability of adsorption but also achieves smooth transfer of the blister pack, solving the problem of material damage that is easily caused by traditional single-stage telescopic mechanisms during adsorption and transfer of blister packs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, a suction and discharge device of a tray feeding machine discharge system is used to absorb and transfer the medicine plate on the first working surface 100 of the tray feeding machine discharge end to the second working surface 200.

[0025] A drive assembly 300 is provided above the first working surface 100. The drive assembly 300 includes a slider 302 and a drive part 301. The drive part 301 is used to drive the slider 302 to move horizontally from directly above the first working surface 100 to directly above the second working surface 200.

[0026] Below the slider 302 is an adsorption section 400 for adsorbing the medicine plate;

[0027] The slider 302 is connected to the adsorption part 400 by a telescopic component 500. The telescopic component 500 is used to drive the adsorption part 400 to move vertically downward in two stages. When one stage is in a fully contracted state and the other stage is in a fully extended state, the lower end of the adsorption part 400 is in contact with the upper end surface of the medicine plate on the first working surface 100.

[0028] It should be noted that the blister pack includes a tray and an aluminum film. The medicine is placed in the tray, and the aluminum film covers the tray for sealing. The blister pack produced by the tray feeding machine is conveyed to the first working surface 100, and the aluminum film of the blister pack on the first working surface 100 is placed in a facing position.

[0029] Initially, the telescopic assembly 500 is in a fully retracted state. The slider 302 is driven horizontally to directly above the first working surface 100 by the drive unit 301. Then, only one stage of the telescopic assembly 500 is activated to extend it to its fully extended state. At this time, the lower end of the adsorption part 400 is in contact with the upper end surface of the medicine plate, and the adsorption part 400 is activated to adsorb the medicine plate on the first working surface 100. Then, the drive unit 301 drives the slider 302, the telescopic assembly 500, and the adsorption part 400 to move to directly above the second working surface 200. Finally, another stage of the telescopic assembly 500 is activated to extend it, continuing to drive the adsorption part 400 to move downward, so that the adsorption part 400 and the medicine plate continuously move downward toward the second working surface 200. When the medicine plate is about to approach the second working surface 200, the adsorption part 400 is closed to release the medicine plate, so that the medicine plate falls onto the second working surface 200.

[0030] This application achieves precise control of the blister pack transfer process by setting up a telescopic component 500 with two-stage telescopic movement function, in conjunction with a horizontal drive component 300. When one stage of the telescopic component 500 is fully extended while the other stage remains retracted, the adsorption part 400 can accurately adhere to the upper surface of the blister pack without excessive pressure, thus avoiding damage to the aluminum film sealing structure. After being transferred to the second working surface 200, the height of the blister pack is gradually reduced by the extension of the other stage of the telescopic component 500, so that the blister pack is released only when it is close to the second working surface 200, effectively preventing falling impact caused by excessive height difference. This two-stage alternating telescopic working mode not only ensures the reliability of adsorption but also achieves the smooth transfer of the blister pack, solving the problem of material damage that is easily caused by traditional single-stage telescopic mechanisms during adsorption and transfer of blister packs.

[0031] Preferably, the second working surface 200 is the upper end surface of the belt conveyor;

[0032] Preferably, the drive assembly 300 is fixedly mounted on an external mounting bracket.

[0033] The telescopic assembly 500 includes a first telescopic part 501 placed vertically downwards, the first telescopic part 501 is vertically fixed to the slider 302, the output end of the first telescopic part 501 is fixed to a first mounting plate 502, a second telescopic part 503 placed vertically downwards is fixed to the first mounting plate 502, the output end of the second telescopic part 503 is fixed to a second mounting plate 504, and the adsorption part 400 is installed below the second mounting plate 504.

[0034] The telescopic assembly 500 achieves two-stage telescopic movement through the independently operating first telescopic part 501 and second telescopic part 503.

[0035] The drive assembly 300 also includes a horizontally placed slide rail 303, on which the slider 302 is slidably connected; the slide rail 303 improves the stability and guidance of the slider 302 during movement.

[0036] Preferably, the drive unit 301 includes a linear motor, a lead screw transmission mechanism, etc.

[0037] Preferably, the slide rail 303 is provided with a detection part at one end directly above the second working surface 200, and the detection part is used to monitor the position of the slider 302;

[0038] Preferably, a PLC controller is also provided on the slider 302. The PLC controller controls the working state of the telescopic component 500 and the adsorption part 400 according to the detection signal of the detection unit.

[0039] Preferably, the PLC controller and the detection unit transmit signals wirelessly;

[0040] Preferably, the detection unit includes a photoelectric sensor or a position sensor, etc.

[0041] When the slider 302 is detected to be directly above the first working surface 100, the medicine plate adsorption operation is performed. The PLC controller controls either the first telescopic part 501 or the second telescopic part 503 to open and extend downward so that the adsorption part 400 is close to the medicine plate. When the slider 302 is detected to be directly above the second working surface 200, the PLC controller controls the telescopic assembly 500 to perform a second extension so that the adsorption part 400 and the medicine plate are close to the second working surface 200. After the telescopic assembly 500 completes the second extension operation, the PLC controller controls the adsorption part 400 to release the medicine plate. After the medicine plate is released, the telescopic assembly 500 opens again so that both the first telescopic part 501 and the second telescopic part 503 are in a fully retracted state.

[0042] The adsorption unit 400 includes a horizontally placed connecting strip 401, which is fixed to the lower end of the second mounting plate 504. Multiple vacuum suction cups 402 are provided at the lower end of the connecting strip 401, and the multiple vacuum suction cups 402 are arranged along the axial direction of the connecting strip 401. The vacuum suction cups 402 adsorb or release the medicine plate.

[0043] Multiple connecting strips 401 are placed side by side; each of the multiple connecting strips 401 corresponds to a row of medicine plates on the first working surface 100, so as to simultaneously adsorb and transfer multiple rows of medicine plates.

[0044] Each connecting strip 401 has an air cavity 4011, and one end of each vacuum suction cup 402 is connected to the corresponding air cavity 4011 in the connecting strip 401.

[0046] Preferably, the negative pressure source can be an oil-free rotary vane vacuum pump;

[0047] Preferably, the air pipe 404 is equipped with a main solenoid valve to control the on / off state of the entire air circuit system; each branch pipe 403 is equipped with a secondary solenoid valve at the connection point near the air chamber 4011 of the connecting strip 401, to independently control the operation of the vacuum suction cup 402 on the corresponding connecting strip 401.

[0049] Preferably, both the trachea 404 and the branch tube 403 are made of polyurethane tubing;

[0050] When adsorption is needed, the negative pressure source is activated and the corresponding solenoid valve is opened.

When releasing, simply turn off the negative pressure source and keep the solenoid valve open. The system can detach the medicine plate by relying on natural pressure relief.

[0051] Preferably, the trachea 404 is also equipped with a pressure relief valve. When the pressure relief valve is opened, the trachea 404 is connected to the outside world to enable rapid release of the medicine plate.
