Description

Technical Field

[0001] This invention mainly relates to the field of transformer testing technology, specifically to an automatic testing and gluing box-making machine. Background Technology

[0002] Cartoning machines are a type of packaging machinery, including automatic cartoning machines and pharmaceutical cartoning machines. Automatic cartoning machines automatically pack medicine bottles, blister packs, ointments, and instructions into folded cardboard boxes and close them. Some more advanced automatic cartoning machines also have additional functions such as affixing sealing labels or performing heat shrink wrapping. Some machines also have a workflow that uses an adhesive dispensing mechanism to seal the opening of the folded cardboard box.

[0003] In the invention patent application CN202020216934.X, published on October 23, 2020, entitled "A Horizontal Cartoning Machine," the following components are included: a cartoning machine body, a horizontal fixed support, a cylinder, an elastic medicine box pressing block, a conveyor belt, a drive motor, a support plate A, a first limiting mechanism, a telescopic frame A, a support plate B, a second limiting mechanism, and a telescopic frame B. The key feature is that a horizontal fixed support is provided at the top of the cartoning machine body, the cylinder is mounted on the horizontal fixed support, and the elastic medicine box pressing block... The box pressing block is located at the bottom of the cylinder, the conveyor belt is located at the inner bottom of the cartoning machine body, the drive motor is electrically connected to the outer bottom of the cartoning machine body, the support plate A is located at both ends of the telescopic frame A, the first limiting mechanism is located on the left side of the cartoning machine body, the support plate B is located at both ends of the telescopic frame B, and the second limiting mechanism is located on the right side of the cartoning machine body. This type of horizontal cartoning machine effectively improves the working efficiency of medicine box packaging, has high adjustment flexibility, is easy to use intelligently, and has a simple structure and strong practicality.

[0004] In the specific implementation process, the inventor found that the device can only complete the boxing process but cannot perform the glue sealing process at the opening of the folded cardboard box. Furthermore, if an empty box occurs during the boxing process, the internal condition cannot be detected in a timely manner. In some devices with built-in sealing, the internal condition of the folded cardboard box cannot be detected when an empty box has already been sealed. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve

[0006] The present invention provides an automatic detection and dispensing cartoning machine to solve the problems mentioned above, which can only complete the cartoning process but cannot perform the dispensing and sealing process at the opening of the folded carton. At the same time, when an empty carton occurs during the cartoning process, the internal condition cannot be detected in time. In some machines with built-in sealing, when an empty carton occurs, the sealing process has already been completed, making it even more impossible to detect the internal condition of the folded carton.

[0011] Furthermore, the push rod is disposed on the upper surface of the inner material conveyor belt, and the push rod forms a telescopic transmission structure through a telescopic cylinder, with the telescopic direction of the push rod corresponding to the position of the box body unfolding structure.

[0012] Furthermore, the unfolded box structure includes a column, a mounting side connecting rod is fixedly connected to one side of the column, a shaping frame is fixedly connected to the other end of the side connecting rod, an adjusting rod is threadedly connected to the surface of the column, a rotating handle is movably connected to the surface of the adjusting rod, and a cardboard adjusting frame is movably connected to the other end of the adjusting rod.

[0013] Furthermore, there are only two of the uprights, side connecting rods, adjusting rods, and cardboard adjustment frames, which are fixed to the upper surface of the extended side platform respectively. The distance between the cardboard adjustment frames is adjusted by rotating the adjusting rods on the surface of the uprights.

[0014] Furthermore, the shaping frame is configured with a larger opening at the top and a smaller exit at the bottom, and an inclined slide is provided at the opening at the top of the shaping frame.

[0015] Furthermore, the pressing block is pressed by the swing plate. The interval dispensing device includes a hollow rod, a rotating transmission rod is movably connected inside the hollow rod, a transmission belt is driven to the surface of the rotating transmission rod, an induction motor is driven to the other end of the transmission belt, a fan-blade storage wheel is fixedly connected to the surface of the rotating transmission rod, a disc storage cavity is fixedly connected to the other side surface of the hollow rod, an adhesive refill tank is provided on the top surface of the disc storage cavity, a dispensing gun nozzle is fixedly connected to the lower surface of the disc storage cavity, and elastic sensing rods are provided between the box fixing blocks on the surface of the finished product conveyor belt.

[0016] Furthermore, the hollow rod is installed on both sides of the frame platform via bearing clips, the disc storage cavity is fixedly suspended above the product conveyor belt via the hollow rod, the fan-blade storage wheel is installed inside the disc storage cavity, and the fan-blade storage wheel inside the disc storage cavity is rotated by a rotating transmission rod, the induction motor receives the induction signal through the elastic induction rod on the surface of the finished product conveyor belt, performs transmission operation, drives the transmission belt and the rotating transmission rod to rotate, and then drives the fan-blade storage wheel to rotate, which in turn drives the glue refill tank to the glue dispensing nozzle to apply glue to the surface of the packaging box on the surface of the finished product conveyor belt.

[0017] Furthermore, the robotic arm adsorbs the cardboard from the inner surface of the cardboard adjustment frame onto the top of the shaping frame. After the cardboard is unfolded inside the shaping frame via the inclined slide on the surface of the shaping frame, it is placed between the box fixing blocks on the surface of the finished product conveyor belt. Finally, the loading is pushed into the unfolded cardboard by the push rod in the loading structure, while the elastic sensing rod is pressed down.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0020] This invention is rationally designed. During the boxing operation, a telescopic cylinder in the loading structure drives a push rod to move the material on the surface of the inner material conveyor belt to the surface of the finished product conveyor belt. Before this, a rotating handle in the box unfolding structure drives an adjusting rod to rotate and move on the column surface, pushing the cardboard adjusting frame to move and adjust the distance between the cardboard adjusting frames, thereby adjusting the size of the folded cardboard box between the cardboard adjusting frames. This achieves the purpose of adjusting different sizes. A robotic arm removes the folded cardboard box from the surface of the cardboard adjusting frame and places it on the upper surface of the shaping frame. After passing through the inclined slide on the surface of the shaping frame, the cardboard unfolds inside the shaping frame and is placed between the box fixing blocks on the surface of the finished product conveyor belt. At the same time, the push rod pushes the material on the surface of the inner material conveyor belt into the folded cardboard box, completing the loading operation.

[0021] Simultaneously, under the influence of gravity, the folded cardboard box presses down the elastic sensing rod on the surface of the finished product conveyor belt. At the same time, the conveyor roller moves the finished product conveyor belt and the boxes on its surface. The elastic sensing rod below the finished product conveyor belt passes above the induction motor in the interval dispensing device, causing the induction motor to receive a sensing signal and start working. This drives the transmission belt and rotating transmission rod to rotate, causing the fan-blade storage wheel to rotate inside the disc storage cavity. The fan-blade storage wheel carries the glue from the glue refill tank to the dispensing gun nozzle below the disc storage cavity. The dispensing gun nozzle then dispenses glue onto the folded cardboard box on the surface of the finished product conveyor belt, ultimately completing the sealing process. During this process, if the folded cardboard box is empty, its weight is insufficient to fully press down the elastic sensing rod, preventing the induction motor from receiving a sensing signal. Therefore, the empty folded cardboard box will not undergo glue dispensing and will remain in a non-sealed state, facilitating timely detection of empty boxes. Additionally, a leakage exhaust fan can blow the empty folded cardboard box off the surface of the finished product conveyor belt, achieving the purpose of automatically detecting empty boxes.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example

[0035] See attached document Figure 1-7 The invention includes a loading structure 1, a frame platform 2 on one side surface of the loading structure 1, a robotic arm 3 on the upper surface of one side of the frame platform 2, extended side platforms 4 on both sides of the frame platform 2, a box unfolding structure 5 on the upper surface of the extended side platforms 4, a leakage exhaust fan 6 on the upper surface of the frame platform 2, a transport roller 7 on the inner surface of the frame platform 2, a finished product transport belt 8 on the surface of the transport roller 7, an interval glue-drip device 9 on the upper surface of the finished product transport belt 8 and the surface of the frame platform 2, and several box fixing blocks on the surface of the finished product transport belt 8. The finished product transport belt 8 is sleeved and connected to the surface of the transport roller 7 to form a transmission structure, and a transport motor is provided on one side of the transport roller 7. The invention pushes the inner contents into the unfolded folded cardboard box through the loading structure 1, and presses down the elastic sensing rod 909 on the surface of the finished product transport belt 8 to determine whether the elastic sensing rod 909 is working, thereby achieving the purpose of glue-drip operation on the folded cardboard box and avoiding the failure to detect empty box seals.

[0036] The loading structure 1 includes a bottom support rod 101, an installation box 102 is provided on the upper surface of the bottom support rod 101, an inner material conveyor belt 103 is provided on the surface of the installation box 102, a pallet 104 is fixedly connected to one side surface of the installation box 102, a telescopic cylinder 105 is provided on the upper surface of the pallet 104, a push rod 106 is provided on one side surface of the telescopic cylinder 105, the push rod 106 is provided on the upper surface of the inner material conveyor belt 103, and the push rod 106 forms a telescopic transmission structure through the telescopic cylinder 105, and the telescopic direction of the push rod 106 corresponds to the position of the box unfolding structure 5.

[0037] In this embodiment, when the boxing operation is performed, the telescopic cylinder 105 in the loading structure 1 drives the push rod 106 to push the material on the surface of the inner material conveyor belt 103 to the surface of the finished product conveyor belt 8, in preparation for boxing.

[0038] The unfolding structure 5 of the box includes a column 501. A mounting side connecting rod 502 is fixedly connected to one side of the column 501, and a shaping frame 503 is fixedly connected to the other end of the side connecting rod 502. An adjusting rod 504 is threadedly connected to the surface of the column 501. A rotating handle 505 is movably connected to the surface of the adjusting rod 504. A cardboard adjusting frame 506 is movably connected to the other end of the adjusting rod 504. There are only two columns 501, side connecting rods 502, adjusting rods 504, and cardboard adjusting frames 506, which are respectively fixed to the upper surface of the extension side platform 4. The cardboard adjusting frame 506 is connected to the column 501 via the adjusting rod 504. The distance between the rotating cardboard adjustment frames 506 on the surface of 01 is adjusted. The shaping frame 503 is set with a larger opening at the top and a smaller exit at the bottom. The upper opening of the shaping frame 503 is provided with an inclined slide. The robotic arm 3 adsorbs the cardboard on the inner surface of the cardboard adjustment frame 506 to the top of the shaping frame 503. After passing through the inclined slide on the surface of the shaping frame 503, the cardboard is unfolded inside the shaping frame 503 and placed between the box fixing blocks on the surface of the finished product conveyor belt 8. Finally, the material is pushed into the unfolded cardboard by the push rod 106 in the loading structure 1, while the elastic sensing rod 909 is pressed down.

[0039] In this embodiment, prior to this, the rotating handle 505 in the box unfolding structure 5 drives the adjusting rod 504 to rotate and move on the surface of the column 501, pushing the cardboard adjusting frame 506 to move, adjusting the distance between the cardboard adjusting frames 506, and thus adjusting the size of the folded cardboard box between the cardboard adjusting frames 506, thereby achieving the purpose of adjusting different sizes. The robotic arm 3 takes out the folded cardboard box from the surface of the cardboard adjusting frame 506 and places it on the upper surface of the shaping frame 503. After passing through the inclined slide on the surface of the shaping frame 503, the cardboard unfolds inside the shaping frame 503 and is placed between the box fixing blocks on the surface of the finished product conveyor belt 8. At the same time, the pushing rod 106 pushes the material on the surface of the inner material conveyor belt 103 into the folded cardboard box, completing the loading operation.

[0040] The interval dispensing device 9 includes a hollow rod 901, a rotating transmission rod 902 movably connected inside the hollow rod 901, a transmission belt 903 drivingly connected to the surface of the rotating transmission rod 902, an induction motor 904 drivingly connected to the other end of the transmission belt 903, a fan-blade storage wheel 905 fixedly connected to the surface of the rotating transmission rod 902, a disc storage cavity 906 fixedly connected to the other side surface of the hollow rod 901, an adhesive refill tank 907 provided on the top surface of the disc storage cavity 906, a dispensing nozzle 908 fixedly connected to the lower surface of the disc storage cavity 906, and elastic sensing rods 909 arranged between the box fixing blocks on the surface of the finished product conveyor belt 8. 901 is installed on both sides of the frame platform 2 via bearing clips. The disc storage cavity 906 is fixedly suspended above the finished product conveyor belt 8 via hollow rod 901. The fan-shaped storage wheel 905 is installed inside the disc storage cavity 906. The fan-shaped storage wheel 905 inside the disc storage cavity 906 is rotated by the rotating transmission rod 902. The induction motor 904 receives the induction signal through the elastic induction rod 909 on the surface of the finished product conveyor belt 8 and performs transmission operation, driving the transmission belt 903 and the rotating transmission rod 902 to rotate, thereby driving the fan-shaped storage wheel 905 to rotate. The glue refill tank 907 is rotated and driven to the glue dispensing nozzle 908 to apply glue to the surface of the packaging box on the surface of the finished product conveyor belt 8.

[0041] In this embodiment, the folded cardboard box, under the action of gravity, presses the elastic sensing rod 909 on the surface of the finished product conveyor belt 8 downwards. Simultaneously, the conveyor roller 7 moves the finished product conveyor belt 8 and the box body on its surface. The elastic sensing rod 909 below the finished product conveyor belt 8 passes above the induction motor 904 in the interval dispensing device 9, causing the induction motor 904 to receive a sensing signal and start working. This drives the transmission belt 903 and the rotating transmission rod 902 to rotate, causing the fan-blade storage wheel 905 to rotate inside the disc storage cavity 906, allowing the fan-blade storage wheel 905 to dispense glue from the glue refill tank 907. Water is driven to the glue gun nozzle 908 below the disc storage cavity 906. The glue gun nozzle 908 applies glue to the folded cardboard boxes on the surface of the finished product conveyor belt 8, and finally completes the sealing operation. During this process, if the folded cardboard box is empty, its weight is insufficient to fully press down the elastic sensing rod 909, so that the sensing motor 904 does not receive the sensing signal. In the end, the empty folded cardboard box will not undergo glue application and will always be in an unsealed state, so as to detect the empty box in time. At the same time, the empty folded cardboard box can also be blown off the surface of the finished product conveyor belt 8 by the leakage exhaust fan 6, realizing the purpose of automatic detection of whether the box is empty.

[0042] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
