Description

Technical Field

[0001] The utility model relates to the technical field of gasket adding devices, in particular to an automatic gasket adding device with a detection function. Background Art

[0002] In the pharmaceutical packaging industry, some drugs are light-sensitive and must be stored in a dark environment to prevent degradation or deterioration of the active ingredients. For this reason, bottle caps with metal foil gaskets are often used in pharmaceutical packaging. The foil's light-shielding and sealing properties ensure drug stability, placing high demands on the gasketing mechanism used in bottle caps.

[0003] Traditional gasketing devices usually position the metal foil surface upward based on the size difference between the front and back sides of the gasket, such as structural features such as chamfers and protrusions on the metal foil surface, through a vibrating plate or a mechanical guide mechanism. However, when installing the gasket, the gasketing device cannot detect the missing gasket or the gasket accidentally flipping over in the bottle cap. This also requires the bottle cap to undergo manual re-inspection after the gasket is added, which will undoubtedly reduce production efficiency and increase production costs. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: an automatic gasket adding device with a detection function, comprising a workbench, a turntable and a positioning plate arranged on the workbench, and a bottle cap feeding mechanism, a gasket feeding mechanism, a pressing cylinder, a photoelectric sensor, a pick-up track, a discharge track and a discharge cylinder arranged around the turntable, the turntable being rotatably connected to the positioning plate, and the turntable being provided with station slots distributed in a circumference for accommodating bottle caps, and the discharge cylinder being arranged at the pick-up track and the discharge track;

[0005] The bottle cap feeding mechanism includes a first vibrating plate, a first track, a fixed plate and a material blocking cylinder. The discharge end of the first vibrating plate is connected to the first track. The first vibrating plate moves the bottle caps with the openings facing upwards into the work station slots through the first track. The positioning plate is provided with a fixed plate at the first track. The fixed plate is connected to the material blocking cylinder for ensuring orderly conveyance of the bottle caps.

[0006] The gasket feeding mechanism includes a second vibrating plate, a second track, a cylinder module, a movable seat and a negative pressure pipe. The discharge end of the second vibrating plate is connected to the second track. The second vibrating plate moves the gasket with the foil surface facing upward to one end of the second track. A cylinder module for controlling the movement of the movable seat is provided on one side of the second track. The movable seat is fixedly connected to a negative pressure pipe for adsorbing the gasket, and the movable seat transfers the gaskets one by one from the second track to the work station slot through the cylinder module.

[0007] By adopting the above technical solution, the bottle caps are placed on the turntable through the bottle cap feeding mechanism, the gaskets are placed in the bottle caps through the gasket feeding mechanism, and the gaskets are pressed against the bottom of the bottle caps by the pressing cylinder. The bottle caps will pass through the photoelectric sensor, which detects the intensity of the reflected light from the gasket by emitting infrared light, thereby identifying whether the foil layer of the gasket is facing upward. If the intensity of the reflected light is lower than the standard value, the bottle cap is unqualified and is pushed out from the rejection track by the discharge cylinder. Otherwise, qualified products are pushed out from the discharge track, effectively eliminating unqualified situations such as no gasket, gasket installed upside down or missing foil layer, ensuring that each bottle cap meets the requirements of sealing and light shielding, guaranteeing the qualified rate of finished products from the source, and reducing the cost of manual re-inspection.

[0008] The utility model is further configured such that the turntable is coaxially distributed on the positioning disk, and the positioning disk is respectively provided with a first opening slot, a second opening slot and a third opening slot for feeding and discharging materials at the first track, the material removal track and the material discharging track.

[0009] With the above technical solution, the first opening slot is used to guide the bottle caps into the work station slot of the turntable. Through the identification of the photoelectric sensor, unqualified products and qualified products are pushed out from the second opening slot and the third opening slot respectively, thereby achieving the purpose of sorting qualified products.

[0010] The utility model is further configured such that the fixing plate is in an X-shape, both ends of the fixing plate are threadedly connected to the positioning plate located on both sides of the first opening slot, and the output end of the material blocking cylinder is located above the first opening slot.

[0011] With the above technical solution, when the bottle cap moves from the first opening slot to the work station slot, the output end of the blocking cylinder presses down the next bottle cap tightly, avoiding interference between subsequent bottle caps and the turntable, and accurately controlling the bottle caps to enter the turntable one by one.

[0012] The utility model is further configured such that the material removal track / discharging track is provided with a mounting frame, the discharging cylinder is mounted on the top surface of the mounting frame, and the output end of the discharging cylinder is provided with a push plate for unloading.

[0013] By adopting the above technical solution, the height of the bottle cap is higher than the depth of the station slot, so that the bottle cap is higher than one end of the turntable to form a force surface, which satisfies the need to push the bottle cap out of the turntable through the push plate. The overall structure is simple and reliable.

[0014] The utility model is further configured such that the gasket feeding mechanism also includes a dividing seat, a dividing plate and a dividing cylinder. The second track is fixedly connected to the dividing seat, the dividing seat is slidably connected to the dividing plate, the dividing seat is fixedly connected to the dividing cylinder for controlling the movement of the dividing plate, and the dividing plate is provided with a dividing groove that can only accommodate a single gasket. The dividing plate moves the gaskets one by one to the adsorption position of the negative pressure tube.

[0015] Using the above technical solution, the second track and the negative pressure tube are staggered, and the material distribution cylinder drives the material distribution plate to move back and forth, so that the gaskets move one by one to the adsorption position of the negative pressure tube, preventing the negative pressure tube from acting on other gaskets, and preventing subsequent gaskets from stacking and blocking the second track due to the force of negative pressure.

[0016] The utility model is further configured as follows: the cylinder module includes a fixed seat, an adapter seat, a first linear slide, a second linear slide, an X-axis cylinder and a Z-axis cylinder; the adapter seat is connected to the fixed seat through a transverse sliding connection of the first linear slide; one side of the fixed seat is connected to an X-axis cylinder for controlling the movement of the adapter seat; the movable seat is connected to the adapter seat through a longitudinal sliding connection of the second linear slide; and the top of the adapter seat is connected to a Z-axis cylinder for controlling the movement of the movable seat.

[0017] By adopting the above technical solution, the Z-axis cylinder is used to realize the vertical movement of the movable seat and meet the needs of vertical material picking and discharging, and the X-axis cylinder is used to realize the movement of the movable seat between the turntable and the material distribution seat, so that the movable seat moves in a C-shaped path.

[0018] The utility model is further configured as follows: the bottle cap feeding mechanism is provided with two groups of first rails and material blocking cylinders corresponding to the work station slots, the gasket feeding mechanism is provided with two groups of second rails and negative pressure tubes corresponding to the work station slots, one side of the turntable is provided with two groups of photoelectric sensors corresponding to the work station slots, and the material picking rail is provided with two groups of discharge cylinders corresponding to the work station slots.

The turntable rotates 45° each time for precise positioning, thereby optimizing the distribution of the workstation slots. Some actuators only need to move once to perform synchronous operations on two groups of bottle caps, reducing the operating frequency of actuators such as motors and cylinders, improving production efficiency and increasing the service life of actuators.
