Description

Technical Field

[0001] The utility model belongs to the technical field of medicine packaging box blanking, in particular to a medicine packaging box blanking device. Background Art

[0002] Pharmaceutical dosage forms are mainly divided into liquid preparations and solid preparations, among which solid preparations include powders, tablets, pills, etc. Among them, pills are the most widely used in the industry due to their round shape.

[0003] During the pharmaceutical production process, granules are injected into vials. After a series of processing steps, the vials are placed into paper packaging boxes, which are then sealed to form the finished product. After being unloaded from the unloading equipment, the packaged products are unloaded onto a palletizing table, where a mechanical gripper picks up the stacked boxes and places them into cartons, completing the final processing step.

[0004] However, during the actual unloading process of finished packaging, the boxes are unloaded from multiple rows by the push plate on the unloading equipment, and the boxes fall onto the loading table in an irregular pattern. At this time, the boxes placed side by side are no longer aligned. Therefore, due to the uneven arrangement of the boxes, the mechanical gripper must align the boxes before grabbing them during the actual production process to facilitate the mechanical gripper to place the boxes into the packaging box for palletizing.

[0005] However, since the unloading speed is very fast, it takes a long time to align the packaging boxes manually or using a clamp. Therefore, in the actual working process, the unloading speed of the unloader can only be reduced to meet the needs of the process time.

[0006] Obviously, this method not only seriously affects the production efficiency of the assembly line operation, but also causes the entire process line to have low processing efficiency due to low end-of-line unloading efficiency. Utility Model Content

[0041] Example 1

[0042] like Figure 1-4 As shown, a drug packaging box unloading device includes a rotary unloading mechanism, and the specific structure of the rotary unloading mechanism is as follows:

[0043] The turntable 1 comprises a turntable 1 (the transverse cross-section of the turntable 1 is a square), the bottom of which is driven to rotate by a rotating structure.

[0044] The outer side walls of the turntable 1 are fixedly connected to unloading racks 2 (the unloading racks 2 are fixed to the four side walls of the turntable 1. Specifically, the longitudinal unloading racks 2 are fixedly connected to the front and rear side walls of the turntable 1, and the transverse unloading racks 2 are fixedly connected to the left and right side walls of the turntable 1). The unloading racks 2 are provided with a plurality of parallel feeding troughs 21. The existing unloading equipment pushes the packaging boxes containing medicine bottles into the feeding troughs 21 along the slot ports of the feeding troughs 21 (specifically, the push plate on the existing unloading machine pushes the packaging boxes arranged side by side on the conveyor belt into the feeding troughs 21 along the slot ports of the feeding troughs 21).

[0045] During the working process, the unloading rack 2 on one side first faces the discharge end position of the unloading equipment (this is the loading station). After the packaging box is loaded, it rotates to face the material table (this is the unloading station), and the idle unloading rack 2 reaches the loading station again and is ready to receive the packaging box.

[0046] The turntable 1 is equipped with four push plate mechanisms for pushing the medicine bottle packaging boxes in the trough 21 (corresponding to the position of the unloading rack 2, the front and rear sides of the top of the turntable 1 are respectively equipped with push plate mechanisms that cooperate with the longitudinal unloading rack 2, and the left and right sides of the top of the turntable 1 are respectively equipped with push plate mechanisms that cooperate with the transverse unloading rack 2). When the packaging boxes enter the trough 21 and are aligned by the trough 21, the push plate mechanisms push them onto the feeding platform.

[0047] Specifically, the push plate mechanism includes a push plate 33, the bottom of which is located above the slot of the material trough 21; the push plate 33 mechanism also includes a push cylinder 31 fixedly installed at the top position of the turntable 1 (the cylinder barrel of the cylinder is fixedly installed at the top of the turntable 1), and the piston rod of the push cylinder 31 is fixedly connected to the center position of the push plate 33.

[0048] At the same time, both sides of the upper end of the push plate 33 are slidably connected with long slide rails 32, and the long slide rails 32 are fixedly connected to the cylinder barrel of the push cylinder 31 at the corresponding position.

[0049] During operation, when the push cylinder 31 pushes down, the push plate 33 pushes the packaging box in the material trough 21 toward the outside (normally, the push plate 33 is located at the center of the turntable 1). After pushing the packaging box into the material table, the unloading of the unloading rack 2 is completed.

[0050] By the above-mentioned method, the continuous switching between the rotating unloading racks 2 is realized to realize the uninterrupted and continuous operation of the unloading equipment in unloading the packaging boxes, thereby increasing the fluency of production and processing.

[0051] Secondly, the unloading rack 2 and the shaping trough are used to straighten the row of unloaded boxes, preparing for the subsequent robot to grab the neat boxes, solving the defect of the traditional unloading method that the boxes cannot be neatly arranged, resulting in the robot being unable to grab the boxes.

[0052] Finally, through the horizontal pushing mode of the push plate 33, multiple rows of packaging boxes are synchronously pushed neatly onto the material table.

[0053] Example 2

[0054] like Figure 1-4As shown, this embodiment builds on the structure of Example 1. To achieve compact packaging within the shaping trough, this embodiment avoids gaps between packaging, which would otherwise prevent the robot from accurately grasping the packaging when the packaging is pushed onto the material table. The outer end of the unloading rack 2 is connected to a contact rod mechanism that cooperates with the push plate 33. When the push plate 33 pushes the medicine bottle packaging until it abuts the contact rod mechanism, the medicine bottle packaging is compacted and pushed onto the working equipment.

[0055] Specifically, the touch rod mechanism includes a long touch rod 42 hinged to the outer end of the blanking rack 2; both ends of the long touch rod 42 are fixedly connected to hinge seats 43, and the hinge seats 43 are hinged to the side walls of the blanking rack 2 through pins.

[0056] The touch rod mechanism also includes a rotary motor 41, the output shaft of which is fixedly connected to a hinged seat 43. According to conventional methods, the motor body of the rotary motor 41 is fixedly connected to a motor mounting plate, which is fixed to the side wall of the unloading rack 2 by a plurality of bolts.

[0057] During the working process, before loading the packaging box, the long touch rod 42-hinge seat 43 is located below the unloading rack 2. After the loading of the packaging box is completed, the long touch rod 42-hinge seat 43 is flipped over to the top of the material rack under the action of the rotating motor 41, and the height is lower than the height of the packaging box.

[0058] At this time, under the push of the push plate 33, all the packaging boxes are blocked by the outer long contact rods 42 and pressed against each other with the long contact rods 42 as support positions, thereby solving the defect of hollow positions between the packaging boxes.

[0059] Driven by the rotary motor 41 , the long contact rod 42 flips over to a position above the slot end of the monolithic trough 21 .

[0060] Example 2

[0061] like Figure 1-4 As shown, this embodiment is based on the structure of embodiment 1, and the above-mentioned rotating structure includes a rotating ring 51 fixedly connected to the center position of the bottom of the turntable 1, and the bottom of the rotating ring 51 is rotatably connected to the fixed seat 52, and the bottom of the fixed seat 52 is fixedly connected to the driving rotating motor 54, and the output shaft of the driving rotating motor 54 is fixedly connected to the bottom of the turntable 1 (the output shaft of the driving rotating motor 54 is rotatably connected to the fixed seat 52, and the same as the existing method, the center position of the fixed seat 52 is installed with an appropriate bearing).

[0062] According to the existing method, the bottom of the rotating ring 51 is provided with a plurality of rollers 511 for limited rolling (specifically, a plurality of grooves for limiting rollers are opened at the bottom of the rotating ring 51, and the rollers 511 are limited and rolled in the grooves. Specifically, the volume of the steel balls is reduced after cold treatment, and they are pressed into the grooves, and then limited and rolled in the grooves).

[0063] The roller 511 rolls on top of the fixed base 52. The bottom of the fixed base 52 is fixedly connected to a mounting base 551 via several U-shaped connectors 55. Several fastening screws are assembled and connected to the mounting base 551. Specifically, the mounting base 551 and fastening screw structure enable the entire device to be mounted on a workbench.

[0064] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
