Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, specifically to an automatic lid removal device for a column-type hopper. Background Technology

[0002] Currently, my country's pharmaceutical industry is developing rapidly, and the government is strongly supporting the development and innovation of solid pharmaceutical preparations. Hoppers used in solid pharmaceutical preparations need to be cleaned in a cleaning machine after a period of use. Due to the limited space inside the cleaning machine, existing robotic arms cannot reach inside to remove the hopper lids. Therefore, currently, before moving the hopper into the cleaning machine, the hopper lids need to be removed beforehand, and then the hopper is sent to the cleaning station for thorough cleaning. The hoppers are fed into the cleaning machine from one side and removed from the other side to achieve continuous cleaning. Therefore, the hopper lids need to be removed from the hopper input side of the cleaning machine, moved to the hopper output side, and then reattached. Currently, this action is done manually, resulting in slow cleaning speeds and preventing automation. Therefore, there is an urgent need to design an automatic hopper lid removal device.

It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0025] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0026] like Figures 1 to 3 As shown in the figure, an automatic hopper lid removal device based on a column type is provided in this embodiment of the present invention. It includes a column 1 and a fixed horizontal arm 2 fixed to the top of the column 1. A vertically arranged first telescopic cylinder 3 is fixedly connected to one end of the fixed horizontal arm 2 away from the column 1. An electric suction cup 4 is connected to the driving end of the first telescopic cylinder 3. One end of the electric suction cup 4 is a suction cup surface 401 parallel to the hopper lid.

[0027] The electric suction cup 4 moves up and down relative to the hopper cover under the drive of the first telescopic cylinder 3, and has a cover-removing position where the suction cup surface 401 is in contact with the hopper cover and an initial position where the suction cup surface 401 is away from the hopper cover.

[0028] This setup moves the hopper to a horizontal position relative to the electric suction cup. The first telescopic cylinder then moves the electric suction cup to the cap-removing position. A negative pressure is created on the electric suction cup to attract the cap, and the first telescopic cylinder is then driven to move the electric suction cup back to its initial position, completing the cap removal process. This method is convenient and automates cap removal without manual disassembly, reducing labor costs and improving work efficiency. The electric suction cup is an existing device, not a manually driven component; vacuum adsorption can be controlled remotely.

[0029] It also includes a magnetic switch 5 connected to the first telescopic cylinder 3 and controlling whether the drive end of the first telescopic cylinder 3 can move by controlling the on / off state of the magnetic switch 5 connected to the first telescopic cylinder 3.

[0030] With this setting, in non-operational state, the electric suction cup is locked in the initial position through the connection between the magnetic switch and the first lifting cylinder. When it is determined that the hopper has moved to the corresponding position of the electric suction cup, the connection between the first lifting cylinder and the magnetic switch is disconnected, and the first lifting cylinder is started to move the electric suction cup to the cover removal position, thereby avoiding the accidental start of the first lifting cylinder in non-operational state.

[0031] It also includes a positioning component that positions the hopper horizontally.

[0032] This setting improves the accuracy of hopper positioning.

[0033] The positioning component includes a first positioning plate 61 arranged along the X direction and two second positioning plates 62 located at the two ends of the first positioning plate 61 in the X direction and both arranged along the Y direction. The first positioning plate 61 and the second positioning plate 62 form a positioning groove 63 that has a horizontal positioning function for the hopper support.

[0034] With this setup, the two second positioning plates position the hopper support in the X direction, and the first positioning plate positions the hopper support in the Y direction. The structure is simple and the positioning effect is good.

[0035] The fixed cross arm 2 is arranged along the Y direction. The column 1 is connected to the first positioning cross plate 61 and is located at the center of the two second positioning cross plates 62. The lower end of the column 1 is connected to a central positioning column 11 located at the center of the two second positioning cross plates 62. The central positioning column 11 is provided with a positioning groove 12. A positioning protrusion that matches the shape of the positioning groove 12 and is inserted into the center of the bottom of one side of the hopper support is provided.

[0036] With this setting, the positioning protrusion and positioning groove cooperate to achieve automatic coaxiality between the center of the hopper and the electric suction cup.

[0037] The central positioning post 11 is provided with a positioning detection component 13 for detecting the positioning protrusion in the positioning groove 12.

[0038] This setting determines whether the hopper is in position by detecting whether the positioning bump is in position, and unlocks the magnetic switch only after confirming that it is in position, reducing the possibility of accidental activation.

[0039] The fixed cross arm 2 includes a fixed part 21 and a sliding part 22. The fixed part 21 is fixedly connected to the fixed part 21 at the top of the column 1. One end of the sliding part 22 is sleeved outside the fixed part 21, and the other end is fixedly connected to the first telescopic cylinder 3. A second telescopic cylinder 23 is connected to the fixed part 21. The driving end of the second telescopic cylinder 23 is connected to the sliding part 22. The sliding part 22 moves along the Y direction and its opposite direction under the drive of the second telescopic cylinder 23.

[0040] This setting allows for adjustment of the Y-axis position of the electric suction cup, improving application flexibility.

[0041] The positioning assembly further includes two first positioning angle plates 64 and two second positioning angle plates 65. The first positioning angle plate 64 includes a first support plate 641 and a second support plate 642. The first support plate 641 and the second support plate 642 are arranged perpendicularly to each other and form a first right-angle positioning angle 643.

[0042] The second positioning angle plate 65 includes a third support plate 651 and a fourth support plate 652. The third support plate 651 and the fourth support plate 652 are arranged perpendicularly to form a second right-angle positioning angle 653. The two first right-angle positioning angles 643 and the two second right-angle positioning angles 653 form the four corners of the positioning groove 63.

[0043] Support plate 1 641 is detachably connected to the first positioning horizontal plate 61, support plate 2 642 is detachably connected to the second positioning horizontal plate 62, and support plate 3 651 is detachably connected to the second positioning horizontal plate 62 via threaded parts.

[0044] This setting improves the ease of assembling and disassembling the positioning component and enhances the reliability of positioning.

[0045] The threaded components include a first threaded component 71 and a second threaded component 72. The first positioning horizontal plate 61 is provided with a first strip groove 611 extending in the X direction and adapted to the shape of the first threaded component 71. The tail end of the first threaded component 71 passes through the support plate 641 and the first strip groove 611 and connects with a nut to lock the support plate 641 onto the first positioning horizontal plate 61.

[0046] The second positioning plate 62 is provided with a second strip groove 621 extending in the Y direction and adapted to the shape of the second threaded part 72. The tail end of the second threaded part 72 passes through the second support plate 642 and the second strip groove 621 and is connected to the nut to lock the second support plate 642 to the second positioning plate 62.

[0047] This setting allows for adjustment of the positions of the first and second positioning angle plates according to the size of the material cylinder bracket, improving the applicability to material cylinders of various sizes.

[0048] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
