Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and in particular to a packaging box filling platform. Background Technology

[0002] In the high-end cigarette, gift, and cosmetics industries, split-opening prefabricated boxes are a common form of exterior packaging. During the packaging process, the boxes are typically conveyed to a filling station via a transfer mechanism for positioning. Then, push rods or robotic arms fill the boxes with the desired contents, and the boxes are transported to downstream stations after filling. However, currently, during the filling process at the filling station, the appearance, positioning accuracy, and filling tightness of the filler need to be inspected to avoid severe deformation of the filler or equipment overload damage. Taking cigarette filling as an example, cigarettes can undergo accurate inspection for appearance integrity and material positioning before filling, and the machine can be stopped for inspection if any abnormalities are found. However, for cigarette filling... However, the tightness of the filling material is difficult to detect accurately. Specifically, the ideal fit between the box and the filling material is a slight interference fit, so that the cigarettes will not be damaged by squeezing and deformation inside the box, and the cigarettes will not fall out when the box opening is facing down. The difficulty in accurately detecting the above state leads to poor filling effect, which in turn causes cigarettes to be squeezed and damaged or the opening to fall off. At the same time, the filling station currently used for filling cigarettes is often part of a continuous space on the conveyor belt. When maintenance is needed, the space is relatively limited. When the filling of cigarettes is damaged, the space for cleaning the damaged cigarettes and packaging boxes is small, making cleaning difficult and causing the equipment to be shut down for a long time, which affects production efficiency.

[0003] Therefore, how to accurately determine the filling effect of the filler in the box and improve the maintenance efficiency of the filling position when the filling effect does not meet the design requirements is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a packaging box filling platform to accurately determine the filling effect of the filler in the box and improve the inspection efficiency of the filling position when the filling effect does not meet the design requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A packaging box filling platform, comprising:

[0007] A placement platform for holding packaging boxes to be filled;

[0008] A first connecting rod and a second connecting rod, wherein the second connecting rod is provided with a placement cavity, the first connecting rod is slidably embedded in the placement cavity, and the first end of the first connecting rod is connected to the bottom of the placement platform;

[0009] A pressure sensor is disposed at the bottom of the placement cavity and in contact with the second end of the first connecting rod. The pressure exerted by the packaging box on the placement platform is transmitted to the pressure sensor through the first connecting rod.

[0010] The controller receives the inlet pressure value from the pressure sensor when the filler enters the opening of the packaging box and compares it with the preset pressure range. When the inlet pressure value is outside the preset pressure range, the controller sends a stop signal.

[0011] Preferably, the above-mentioned packaging box filling platform further includes a support rod and an electric push rod. The movable end of the electric push rod is rotatably connected to the rod body of the support rod. The first end of the support rod is fixedly connected to the frame, and the second end of the support rod is rotatably connected to the closed end of the second connecting rod through a rotating pin.

[0012] The first connecting rod is rotatably connected to the bottom of the placement platform. When the movable end is in the extended state, it presses against the support rod. The support rod lifts the second connecting rod and drives the first connecting rod to support the placement platform in the filling position. When the movable end is in the retracted state, it pulls back the support rod. The support rod drives the first connecting rod to rotate and pulls the placement platform away from the filling position.

[0013] Preferably, in the above-mentioned packaging box filling platform, the movable rod of the electric push rod is driven by a first motor to extend or retract, the controller is signal-connected to the first motor, the controller adjusts the first motor to extend the movable end when the inlet pressure value is within the preset pressure range, and adjusts the first motor to drive the movable end to retract after the feedback of the stop signal.

[0014] Preferably, in the above-mentioned packaging box filling platform, when the movable end is in the extended state, the support rod is pressed against and collinear with the axis of the second connecting rod.

[0015] Preferably, in the above-mentioned packaging box filling platform, the first connecting rod is rotatably connected to the bottom cylindrical shaft of the placement platform through a clamping sleeve and a rod end bearing, and the first end of the first connecting rod is fixedly connected to the outer ring of the rod end bearing.

[0016] Preferably, in the above-mentioned packaging box filling platform, the movable end of the electric push rod is rotatably connected to the support rod at the midpoint of its length direction via a pin.

[0017] Preferably, in the above-mentioned packaging box filling platform, a limiting groove is provided on the outer wall of the first connecting rod, and a limiting screw is provided through the side wall of the second connecting rod. One end of the limiting screw extends into the limiting groove, and the relative sliding distance between the first connecting rod and the second connecting rod is the width of the limiting groove.

[0018] Preferably, in the above-mentioned packaging box filling platform, the limiting groove is configured as an annular groove arranged circumferentially along the first connecting rod.

[0019] Preferably, in the above-mentioned packaging box filling platform, a plurality of the limiting screws are evenly arranged along the circumference of the second connecting rod.

[0020] Preferably, in the above-mentioned packaging box filling platform, the first end of the first connecting rod is provided with an internal thread, and the threaded part is welded and fixed on the rod end bearing and fixedly connected to the first end of the first connecting rod by a nut.

[0021] As can be seen from the above technical solution, the packaging box filling platform provided by the present invention includes a placement platform, a first connecting rod, a second connecting rod, a pressure sensor, and a controller. The placement platform is used to support the packaging box and provide filling space. The first connecting rod is movably connected to the second connecting rod. Specifically, the second connecting rod has a placement cavity, and the first connecting rod is embedded in the placement cavity and slides within the cavity's inner wall. Simultaneously, the first end of the first connecting rod is connected to the bottom of the placement platform. The pressure sensor is located at the bottom of the placement cavity and contacts the second end of the first connecting rod. It should be noted that the first connecting rod is rigidly connected to the bottom of the placement platform in its axial direction to effectively transmit the pressure applied to the placement platform to the pressure sensor. The pressure sensor then accurately detects the pressure applied to the packaging box on the placement platform. The controller is connected to the pressure sensor signal to receive the pressure signal detected by the pressure sensor. Specifically, the controller has a preset pressure range input, and the controller receives... The pressure sensor detects the inlet pressure value when the filler enters the packaging box opening and compares it with a preset pressure range. It's important to note that the inlet pressure value represents the pressure exerted on the packaging box when the filler first enters. Since the packaging box's size and the fit with the filler generally have a certain interference fit to ensure the filler is stably placed inside and won't spill out, the pressure exerted by the filler at the packaging box inlet is a key point in process control. It directly reflects whether the filler will be squeezed and damaged when placed inside the packaging box, or whether it can be properly secured. Therefore, the inlet pressure value is selected as the judgment standard. Specifically, when the inlet pressure value is within the preset pressure range, the equipment remains inactive and operates normally. When the inlet pressure value is outside the preset pressure range, a stop signal is fed back to prompt the operator to stop the equipment for maintenance, recalibrate the force and posture of the filler when filling the packaging box, and, after equipment debugging is completed, adjust the controller to restart the equipment to continue the filling process. The packaging box filling platform provided by this invention supports the packaging box and provides a filling position through a placement platform. Simultaneously, a pressure sensor connected to a first connecting rod accurately detects the pressure exerted on the packaging box on the placement platform. A controller receives feedback on the inlet pressure value when the filler enters the opening of the packaging box. The controller compares the inlet pressure value with a preset pressure range. If the inlet pressure value is less than the preset pressure range, the filler cannot be fully inserted into the packaging box; if the inlet pressure value is greater than the preset pressure range, there is a risk of the filler being crushed or damaged. In both cases, the controller will send a stop signal to prompt the operator to perform equipment maintenance. This accurately detects the filling effect within the box, ensuring product production quality. Attached Figure Description

Detailed Implementation

[0029] The core of this invention is to disclose a packaging box filling platform to accurately determine the filling effect of the filler in the box and improve the inspection efficiency of the filling position when the filling effect does not meet the design requirements.

[0030] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0031] like Figure 1-5As shown, the packaging box filling platform provided in this embodiment of the invention includes a placement platform 10, a first connecting rod 20, a second connecting rod 30, a pressure sensor 40, and a controller. The placement platform 10 supports the packaging box 110 and provides filling space for it. The first connecting rod 20 is movably connected to the second connecting rod 30. Specifically, the second connecting rod 30 has a placement cavity, and the first connecting rod 20 is embedded in the placement cavity and slides against the inner wall of the cavity. Simultaneously, the first end of the first connecting rod 20 is connected to the bottom of the placement platform 10, and the pressure sensor 40 is located at the bottom of the placement cavity and contacts the second end of the first connecting rod 20. It should be noted that the first connecting rod 20 is rigidly connected to the bottom of the placement platform 10 in its axial direction, so as to effectively transmit the pressure on the placement platform 10 to the position of the pressure sensor 40. The pressure sensor 40 then accurately detects the pressure on the packaging box 110 on the placement platform 10. The controller is connected to the pressure sensor 40 to receive the pressure signal detected by the pressure sensor 40. Specifically, the controller has a preset pressure range input, and the controller receives the inlet pressure value detected by the pressure sensor 40 when the filler enters the opening of the packaging box 110, and compares the inlet pressure value with the preset pressure range.

[0032] It should be noted that the inlet pressure value refers to the pressure exerted on the packaging box 110 when the filler just enters the inlet. Since the size design of the packaging box 110 and the fit of the filler generally have a certain interference to ensure that the filler is stably placed inside the packaging box 110 and will not be poured out, the pressure exerted by the filler at the inlet of the packaging box 110 is a key point of process control. It can directly reflect whether the filler will be squeezed and damaged when placed into the packaging box 110, or whether it can be well inserted into the packaging box 110. Therefore, the inlet pressure value is selected as the judgment standard. Specifically, when the inlet pressure value is within the preset pressure range, the equipment does not operate and continues to operate normally. When the inlet pressure value is outside the preset pressure range, a stop signal is fed back to prompt the operator to stop the equipment for maintenance, recalibrate the magnitude and posture of the force and posture of the filler when filling the packaging box 110, and adjust the controller to restart the equipment to continue the filling operation after the equipment debugging is completed.

[0033] It should be noted that the preset pressure range in the controller is set by the operator according to the packaging box 110 and the type of filling material in the actual working conditions.

[0034] The packaging box filling platform provided in this embodiment of the invention supports the packaging box 110 and provides a filling position through the placement platform 10. At the same time, a pressure sensor 40 connected to the first connecting rod 20 is used to accurately detect the pressure effect on the packaging box 110 on the placement platform 10. Combined with the controller, the inlet pressure value when the filler enters the opening position of the packaging box 110 is received and fed back. The controller compares the inlet pressure value with a preset pressure range. If the inlet pressure value is less than the preset pressure range, the filler cannot be fully inserted into the packaging box 110. If the inlet pressure value is greater than the preset pressure range, there is a risk of the filler being crushed and damaged. In the above cases, the controller will send a stop signal to prompt the operator to perform equipment maintenance, thereby accurately detecting the filling effect of the filler in the box and ensuring the production quality of the product.

[0035] It should be further explained that the packaging box filling platform 10 provided in this embodiment of the invention preferably integrates a conveying function to cooperate with the production line to convey the packaging box 110. Specifically, a pair of rotating joints are provided at the bottom of the placement platform 10 to drive the belt or the like on the upper surface of the placement platform 10 to rotate and convey. The rotating joints are set parallel to the conveying direction and the placement surface of the placement platform 10. At the same time, the placement platform 10 is rotatably connected to the frame 70 through an independent and rotatable support frame. The placement platform 10 is preset to be in a horizontal state with the frame 70 during assembly, while the support frame is set to rotate along a fixed axis to realize the switching of the placement platform 10 from a horizontal state to an inclined state, thereby providing a larger maintenance space.

[0036] Furthermore, in a specific embodiment of the present invention, a support rod 50 and an electric actuator 60 are also included. One end of the electric actuator 60 is fixedly mounted on the frame 70, and the other end is a retractable movable end 610. The movable end 610 is rotatably connected to the rod body of the support rod 50. It should be noted that the rod body of the support rod 50 refers to the non-end position on the support rod 50. The first end of the support rod 50 is fixedly connected to the frame 70, and the second end of the support rod 50 is rotatably connected to the closed end of the second connecting rod 30 via a rotating pin 510. In the above structure, when the movable end 610 of the electric actuator 60 drives the rod body of the support rod 50 to move, the fixed first end of the support rod 50 will cause the second end of the support rod 50 to rotate, thereby causing the second connecting rod 30 to rotate. Simultaneously, the first connecting rod 20... The movable end 610 is rotatably connected to the bottom of the placement platform 10. When the movable end 610 is in the extended state, it will press against the support rod 50. At this time, the support rod 50 will lift the second connecting rod 30 and drive the first connecting rod 20 to support the placement platform 10 stably in the filling position and perform the filling action. When the movable end 610 is in the retracted state, it will pull back the support rod 50. The support rod 50 will drive the first connecting rod 20 to rotate and pull the placement platform 10 away from the filling position. When the controller sends a stop signal, the equipment stops running. At the same time, the operator drives the electric push rod 60 to retract, which will drive the first connecting rod 20 to rotate and pull the placement platform 10 away from the filling position. At this time, the placement platform 10 will be in an inclined state, which will give the operator more maintenance space, thereby enabling the use of larger maintenance tools and improving maintenance and production efficiency.

[0037] It should be noted that when the movable end 610 of the electric actuator 60 retracts, it will drive the support rod 50 to rotate. The limit of the rotation position of the support rod 50 can be achieved by the anti-rotation pin.

[0038] Based on the above embodiments, preferably, the movable rod of the electric push rod 60 is driven by the first motor to extend or retract. At the same time, the controller is signal-connected to the first motor. Specifically, when the inlet pressure value is within the preset pressure range, the controller adjusts the first motor to extend the movable end 610 to lift the support rod 50, so that the placement table 10 is normally in the filling position. At the same time, after the controller receives a stop signal, it adjusts the first motor to drive the retractable movable end 610 to automatically remove the placement table 10 from the filling position and wait for maintenance.

[0039] Furthermore, in a preferred embodiment of the present invention, when the movable end 610 is in the extended state, the support rod 50 is pressed against and collinear with the axis of the second connecting rod 30. At this time, the support rod 50 is also collinear with the axis of the first connecting rod 20. At this time, the supporting force of the support rod 50 on the placement platform 10 is unidirectional, thereby making its support on the placement platform 10 more stable.

[0040] Furthermore, in a specific embodiment of the present invention, the first connecting rod 20 is rotatably connected to the cylindrical shaft on the bottom structure of the placement platform 10, specifically by setting a clamping sleeve 210 and a rod end bearing 220 for rotatable connection. At the same time, the first end of the first connecting rod 20 is fixedly connected to the outer ring of the rod end bearing 220, so that the first support rod 50 can only rotate in the circumferential direction of the cylindrical shaft, and cannot rotate in the axial direction of the first support rod 50, so that the first support rod 50 can provide good support to the placement platform 10 through its axial force.

[0041] Furthermore, in the packaging box filling platform provided in this embodiment of the invention, the movable end 610 of the electric push rod 60 and the support rod 50 are rotatably connected by a pin at the midpoint of their length direction, so that the lever arm on the support rod 50 is close when the movable end 610 retracts and extends, thereby making the rotation of the support rod 50 more stable.

[0042] Furthermore, in a specific embodiment of the present invention, the first connecting rod 20 is provided with a recessed limiting groove 230 on its outer wall, while the side wall of the second connecting rod 30 is provided with a limiting screw 310 penetrating through it. One end of the limiting screw 310 extends into the limiting groove 230 so that during the relative sliding between the first connecting rod 20 and the second connecting rod 30, the sliding is limited by the limiting screw 310 and the side wall of the limiting groove 230, thereby protecting the pressure sensor 40 and making the sliding action of the first connecting rod 20 and the second connecting rod 30 more stable. Correspondingly, the maximum distance of relative sliding between the first connecting rod 20 and the second connecting rod 30 is the width of the groove 230.

[0043] Based on the above embodiments, the preferred configuration of the limiting groove 230 is an annular groove arranged along the circumference of the first connecting rod 20, so that the limiting screw 310 can be inserted into the limiting groove 230 from any position in the circumferential direction of the second connecting rod 30 and extend into the interior of the limiting groove 230 to achieve the limiting effect.

[0044] To further optimize the above technical solution, it is preferable to have a plurality of limiting screws 310, which are evenly arranged along the circumference of the second connecting rod 30 to cooperate in limiting the first connecting rod 20 and the second connecting rod 30, so as to avoid the limiting effect from being skewed and causing the sliding direction of the first connecting rod 20 to be skewed, thus affecting the accuracy of pressure detection.

[0045] Furthermore, in a specific embodiment of the present invention, the first end of the first connecting rod 20 is provided with an internal thread. Correspondingly, the threaded part is welded and fixed on the rod end bearing 220 and fixedly connected to the first end of the first connecting rod 20 by a nut, which facilitates disassembly and maintenance.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
