[0045] The packaging box transmission line 2 is a conventional belt transmission line or a chain plate transmission line. The packaging box transmission line 2 is provided with a packaging box opening machine 1, a first group of inner tray placement devices 3, a gas meter three-axis picking device 4, a second group of inner tray placement devices 3, a box labeling machine 8, and a box packaging machine 9 in sequence along the transmission direction.

[0046] The feeding end of the packaging box transmission line 2 is provided with a packaging box opening machine 1, which opens the packaging box in the closed state through the packaging box opening machine 1, and then transmits the opened packaging box to the bottom of the first group of inner tray placement devices 3 through the packaging box transmission line 2, picks up the lower inner tray through the first group of inner tray placement devices 3, and places the lower inner tray at the bottom of the inner side of the packaging box. The packaging box is further transmitted to the gas meter three-axis picking device 4, which picks up the gas meter through the gas meter three-axis picking device 4 and places the gas meter on the lower inner tray inside the packaging box to achieve gas meter packaging. The packaging box is further transmitted to the second group of inner tray placement devices 3, which picks up the upper inner tray through the second group of inner tray placement devices 3, and snaps the upper inner tray on the top of the gas meter. The packaging box is further transmitted to the box labeling machine 8, which affixes labels to the packaging box. The packaging box is further transmitted to the box packaging machine 9, which seals the packaging box through the box packaging machine 9 to complete the gas meter packaging operation.

[0047] Specifically, the unfolded carton is transferred to the bottom of the discharge end of the inner support support frame 31, the loading end of the inner support support frame 31 is located on one side of the packaging box transmission line 2, and the bottom of the loading end of the inner support support frame 31 is provided with an inner support lifting and loading device 32, and the top of the inner support support frame 31 is provided with a three-axis inner support grabbing device 33 that moves between the discharge end and the loading end. When the three-axis inner support grabbing device 33 moves to the discharge end, it corresponds to the unfolded carton, and when the three-axis inner support grabbing device 33 moves to the loading end, it corresponds to the lifting end of the inner support lifting and loading device 32. A plurality of lower inner supports or upper inner supports are stacked on the lifting end of the inner support lifting and loading device 32, and the lower inner supports or upper inner supports are lifted upward by the inner support lifting and loading device 32, and the inner support on the top layer is picked up and driven to move to the discharge end in cooperation with the three-axis inner support grabbing device 33, and the discharge end is placed at the bottom of the carton or on the top of the gas meter.

[0048] Embodiment 2:

[0049] This embodiment is further optimized on the basis of embodiment 1. Figure 3 As shown, the inner support lifting and feeding device 32 includes an inner support lifting device 321, an inner support bearing frame 322, and an inner support layering device 323. The inner support lifting device 321 is arranged at the inner support feeding end of the inner support support frame 31 in the vertical direction, the inner support bearing frame 322 is arranged on the lifting end of the inner support lifting device 321, and the inner support layering device 323 is arranged on the top of the inner support lifting device 321.

[0050] The inner support carrier 322 is directly connected to the lifting end of the inner support lifting device 321 through connecting bolts, and a plurality of inner supports are stacked on the inner support carrier 322. The inner support lifting device 321 drives the stacked inner supports to move upward, and when the inner support at the top layer moves to the feeding end, the inner support layering device 323 separates the inner support at the top layer from the rest of the inner supports stacked below, and then the single inner support at the top layer can be picked up by the three-axis inner support grabbing device 33, avoiding picking up multiple inner supports at one time.

[0051] Further, such as Figure 4 As shown, the inner support stratification device 323 includes a stratification mounting frame 3231, a stratification cylinder 3232, and a material dividing baffle 3233. The stratification mounting frame 3231 is arranged at the top of the inner support feeding end of the inner support support frame 31, and the stratification mounting frame 3231 is provided with a jacking opening for the bottom support to pass through; the stratification cylinder 3232 is correspondingly arranged at the edge of the jacking opening, and the telescopic end of the stratification cylinder 3232 is provided with a material dividing baffle 3233 facing the inner side of the jacking opening.

[0052] The layered mounting frame 3231 is a hollow rectangular frame structure, and the hollow part of the layered mounting frame 3231 serves as a jacking opening for the inner support to pass through. At least one layering cylinder 3232 is arranged on each edge of the rectangular frame structure of the layered mounting frame 3231, and a material dividing baffle 3233 is arranged on the telescopic end of the layering cylinder 3232. When the layering cylinder 3232 is in a retracted state, the material dividing baffle 3233 does not block the jacking opening and does not hinder the inner support from passing through the jacking opening. When the single inner support of the top layer passes through the jacking opening upward, and the gap between the inner support of the top layer and the inner support stacked below is aligned with the material dividing baffle 3233, the telescopic end of the layering cylinder 3232 extends toward the inner side of the jacking opening, thereby driving the material dividing baffle 3233 to be inserted into the gap between the inner support of the top layer and the inner support stacked below, so that the inner support of the top layer is separated from the inner support stacked below.

[0053] Furthermore, the material dividing plate 3233 includes a vertical section connected to the telescopic end of the stratification cylinder 3232 and a horizontal section arranged at the bottom of the vertical section, and the vertical section and the horizontal section form an L-shaped structure. The horizontal section of the material dividing plate 3233 is inserted into the gap between the inner support of the top layer and the inner support stacked below, and the vertical section limits the separated inner support.

[0054] Further, such as Figure 5 As shown, the inner support lifting device 321 includes an inner support lifting bracket 3211 arranged at the inner support feeding end of the inner support support frame 31, a lifting screw rod 3212 rotatably arranged on one side of the inner support lifting bracket 3211, an inner support bearing frame 3213 vertically slidably arranged on one side of the inner support lifting bracket 3211, and a lifting drive motor 3214 arranged at the bottom of the inner support lifting bracket 3211, the lifting screw rod 3212 passes through the inner support bearing frame 3213 and is threadedly connected to the inner support bearing frame 3213, and the bottom of the lifting screw rod 3212 is transmission-connected to the output end of the lifting drive motor 3214.

[0055] The inner support bearing frame 3213 is provided with a mounting hole corresponding to the lifting screw rod 3212, and a screw nut is clamped in the mounting hole. The lifting screw rod 3212 passes through the threaded hole on the screw nut and is threadedly connected with the screw nut. A slider is also provided on the side of the inner support bearing frame 3213 close to the inner support lifting bracket 3211, and a vertical slide rail slidably connected to the slider is provided on the side wall of the inner support lifting bracket 3211. The inner support bearing frame 3213 can slide vertically on one side of the inner support lifting bracket 3211 through the sliding connection between the slider and the vertical slide rail.

[0056] The lifting drive motor 3214 drives the lifting screw rod 3212 to rotate, thereby driving the inner support frame 3213 to slide and rise in the vertical direction, thereby lifting the inner support. At the same time, since the matching accuracy of the screw rod and the screw rod nut is high, and the lifting distance of the screw rod is more accurate, the lifting distance control of the inner support frame 3213 is more accurate.

[0057] Preferably, the inner support lifting device 321 can also be replaced with a cylinder lifting device, an oil cylinder lifting device, etc. according to actual use requirements, but the lifting distance control accuracy of the cylinder lifting device and the oil cylinder lifting device is lower than the control accuracy of the screw lifting.

[0058] Furthermore, a positioning boss or a positioning column is provided on the top of the inner support carrier 3213. The inner support is not a flat structure. In order to fix the gas meter, the inner support is provided with corresponding grooves, concave holes, positioning holes, etc. In order to prevent the inner support from falling off the inner support carrier 3213 during the jacking process, a positioning boss or a positioning column is provided on the top of the inner support carrier 3213 corresponding to the grooves, concave holes, positioning holes, etc. on the inner support. The inner support is positioned by cooperating with the positioning boss and the groove or concave hole or by cooperating with the positioning column and the positioning hole, thereby effectively preventing the inner support from moving and falling.

[0059] Furthermore, the three-axis inner support grasping device 33 includes an inner support X-direction moving device, an inner support Y-direction moving device, an inner support Z-direction lifting device, and an inner support sponge suction cup group. The inner support X-direction moving device is arranged between the inner support feeding end and the inner support discharging end, and can move linearly between the inner support feeding end and the inner support discharging end along the X direction; the inner support Y-direction moving device is arranged on the moving end of the inner support X-direction moving device, and the inner support Y-direction moving device can move linearly along the Y direction perpendicular to the X direction; the inner support Z-direction lifting device is arranged on the moving end of the inner support Y-direction moving device, and the inner support Z-direction lifting device can be lifted and lowered along the vertical Z direction, and an inner support sponge suction cup group is arranged on the lifting end of the inner support Z-direction lifting device.

[0060] The X direction is perpendicular to the transmission direction of the packaging box transmission line 2, the Y direction is parallel to the transmission direction of the packaging box transmission line 2, and the Z direction is a vertical direction perpendicular to the ground.

[0061] The inner support X-direction moving device includes X-direction slide rails arranged on both sides of the top of the inner support support frame 31 along the X-direction, X-direction sliders slidably arranged on the X-direction slide rails, an X-direction drag chain arranged in parallel on one side of the X-direction slide rail and connected to the inner support Y-direction moving device, and an X-direction motor for driving the X-direction drag chain to move along the X-direction. The inner support Y-direction moving device is arranged between the X-direction sliders on both sides along the Y-direction. The inner support Y-direction moving device is driven to slide along the X-direction by the X-direction drag chain, thereby driving the inner support Y-direction moving device to move linearly between the loading end and the unloading end along the X-direction.

[0062] The inner support Y-direction moving device comprises a Y-direction bracket arranged between the X-direction sliders on both sides along the Y-direction, a Y-direction screw rod arranged on the Y-direction bracket and rotating along the Y-direction, a Y-direction screw rod nut threadedly mounted on the Y-direction screw rod, and a Y-direction motor connected to one end of the Y-direction screw rod. One side of the Y-direction screw rod nut is connected to the inner support Z-direction lifting device, and the Y-direction motor drives the Y-direction screw rod to rotate, thereby driving the Y-direction screw rod nut to drive the inner support Z-direction lifting device to move linearly along the Y-direction.

[0063] The inner support Z-direction lifting device comprises a Z-direction bracket connected to one side of the Y-direction screw, a Z-direction screw arranged on the Z-direction bracket and rotating along the Z-direction, a Z-direction screw nut threadedly mounted on the Z-direction screw, and a Z-direction motor connected to the top of the Z-direction screw. One side of the Z-direction screw nut is connected to the inner support sponge suction cup group. The Z-direction motor drives the Z-direction screw to rotate, and then drives the Z-direction screw nut to drive the inner support sponge suction cup group to be lifted and lowered along the Z direction.

[0064] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0065] Embodiment 3:

[0066] This embodiment is further optimized on the basis of the above-mentioned embodiment 1 or 2, and a partition placement device 5 and a protective cover installation device 6 are sequentially arranged between the outlet end of the gas meter three-axis picking device 4 and the box labeling machine 8 along the transmission direction.

[0067] Further, such as Figure 6 As shown, the partition placing device 5 includes a shuttle material bracket 51, on which a paper partition shuttle material slit 52 is arranged parallel to the transmission direction, and material clamping supports 53 are slidably arranged at both ends of the paper partition shuttle material slit 52 on the shuttle material bracket 51; a partition shuttle material wheel group 54 is rotatably arranged between the material clamping end surfaces of the material clamping supports 53 at both ends and parallel to the paper partition shuttle material slit 52, and a pushing device 57 is arranged perpendicular to the paper partition shuttle material slit 52 between the material clamping end surfaces of the material clamping supports 53 at both ends; a lifting device 55 is arranged at the bottom opening of the paper partition shuttle material slit 52, and guide wheel groups 56 are respectively arranged on the lifting ends of the lifting devices 55 corresponding to the two ends in the width direction of the paper partition shuttle material slit 52.

[0068] The shuttle support 51 includes a shuttle panel and support columns arranged at the four corners of the bottom of the shuttle panel. The shuttle panel is straddled and arranged on the top of the packaging box conveyor line. A paper partition shuttle slit 52 is provided on the shuttle panel parallel to the transmission direction of the packaging box conveyor line 2. The length of the paper partition shuttle slit 52 is greater than the length of the paper partition, and the width of the paper partition shuttle slit 52 is greater than or equal to the width of the paper partition, so that the paper partition can smoothly fall between adjacent gas meters in the packaging box through the paper partition shuttle slit 52. The top of the shuttle panel is located at both ends of the paper partition shuttle slit 52 and are slidably provided with material clamping supports 53. The material clamping supports 53 include material clamping end faces arranged toward the paper partition shuttle slit 52, and the material clamping end faces of the material clamping supports 53 at both ends constitute a material clamping area. A plurality of arranged paper partitions are placed in the material clamping area, and the two ends of the paper partitions are clamped by the material clamping end faces of the material clamping supports 53 at both ends to prevent the paper partitions from moving along the width direction of the shuttle panel.

[0069] After the paper partitions are arranged and placed in the clamping area and clamped by the clamping support 53, the paper partitions can be pushed toward the direction close to the paper partition shuttle gap 52 by the pushing device 57 until the paper partition closest to the paper partition shuttle gap 52 contacts the rim of the partition shuttle wheel in the partition shuttle wheel group 54. At this time, the paper partitions in contact with the rim of the partition shuttle wheel in the partition shuttle wheel group 54 also move to the position corresponding to the paper partition shuttle gap 52, and the friction force generated by the rotation of the partition shuttle wheel in the partition shuttle wheel group 54 can drive the paper partition downward through the paper partition shuttle gap 52 and fall to the bottom of the shuttle panel.

[0070] After the paper partition passes downward through the paper partition shuttle slit 52, it contacts the rim of the guide wheel in the guide wheel group 56. At the same time, when the paper partition passes through the paper partition shuttle slit 52, the lifting device 55 arranged under the shuttle panel corresponding to the paper partition shuttle slit 52 drives the guide wheel group 56 to move downward with the paper partition, thereby guiding the falling of the paper partition, so that the paper partition can basically maintain a vertical state and fall between adjacent gas meters inside the packaging box, thereby separating the gas meters.

[0071] Further, such as Figure 7 and Figure 8 As shown, the guide wheel group 56 includes a guide wheel frame 561 which is arranged at the bottom opening of the paper partition shuttle material slit 52 and connected to the lifting end of the lifting device 55, and the guide wheel frame 561 is provided with a plurality of guide wheels 562 which are linearly rotated in the vertical direction corresponding to both sides of the bottom opening of the paper partition shuttle material slit 52; the bottom of the guide wheel frame 561 is also provided with a support wheel 563 which is rotatably arranged corresponding to both sides of the bottom opening of the paper partition shuttle material slit 52.

[0072] Specifically, the guide wheel frame 561 is provided with a first group of guide wheels 562 and a second group of guide wheels 562 in the vertical direction. The first group of guide wheels 562 and the second group of guide wheels 562 are respectively provided on both sides of the width direction of the paper separator shuttle slit 52. Here, the width direction of the paper separator shuttle slit 52 refers to the direction in which the paper separator shuttle slit 52 is narrower. The gap between the rims of the first group of guide wheels 562 and the rims of the second group of guide wheels 562 forms a gap for the paper separator to fall, and the gap between the rims of the first group of guide wheels 562 and the rims of the second group of guide wheels 562 is greater than or equal to the thickness of a single paper separator. When a single paper partition passes through the paper partition shuttle slit 52 and falls downward, the bottom of the single paper partition enters the gap between the rims of the first set of guide wheels 562 and the rims of the second set of guide wheels 562, and at the same time, the lifting device 55 drives the guide wheel frame 561 to fall with the falling of the single paper partition, and guides the single paper partition to fall vertically through the rims of the first set of guide wheels 562 and the rims of the second set of guide wheels 562, so that the single paper partition remains in a vertical state and falls into the interior of the packaging box. The gap between the rims of the first set of guide wheels 562 and the rims of the second set of guide wheels 562 is 1-1.5 times the thickness of the single paper partition.

[0073] Specifically, at the bottom of the guide wheel frame 561, corresponding to the paper partition shuttle material seam 52, there are opening wheels 563 on both sides of the width direction, and the gap between the wheel rims of the opening wheels 563 on both sides is greater than or equal to the thickness of a single paper partition, so as to ensure that a single paper partition can fall smoothly without being blocked. When the guide wheel frame 561 is driven down by the lifting device 55, the opening wheel 563 at the bottom of the guide wheel frame 561 is driven to enter the gap between two adjacent gas meters inside the packaging box, and the two adjacent gas meters are relatively opened by the opening wheel 563, so that the fallen single paper partition can fall smoothly between the two adjacent gas meters. After the paper partition falls between the adjacent gas meters, the lifting device 55 drives the guide wheel frame 561 to rise, so that the opening wheel 563 escapes from the gap between the adjacent gas meters.

[0076] A plurality of partition shuttle wheels 542 are sleeved on each transmission shaft 541 along the axial line, and the wheel rim of the partition shuttle wheel 542 is arranged corresponding to the paper partition shuttle slit 52 and contacts one side of the paper partition. The shuttle drive motor 543 drives the plurality of transmission shafts 541 to rotate synchronously, thereby driving the partition shuttle wheels 542 to rotate, and then the friction between the partition shuttle wheels 542 and the paper partition drives the paper partition downward through the paper partition shuttle slit 52.

[0077] Furthermore, a transmission gear is provided at one end of the transmission shaft 541, and the transmission gears at one end of adjacent transmission shafts 541 are connected through a transmission chain; and the shaft end of at least one transmission shaft 541 is also connected to the output end of the shuttle drive motor 543 through a transmission chain.

[0078] Furthermore, an output gear is mounted on the output shaft of the shuttle drive motor 543 , and the output gear is connected to the transmission gear at one end of the transmission shaft 541 through a transmission chain.

The instruction manual placement rack 72 is provided with a cavity for the instruction manual to be stacked from top to bottom, and a feeding device 73 is provided at the bottom of the cavity on the inner side of the instruction manual placement rack 72. The feeding direction of the feeding device 73 is arranged toward the shuttle opening, and the end of the feeding device 73 away from the shuttle opening is higher than the end of the feeding device 73 close to the shuttle opening and is in an inclined state toward the shuttle opening. The stacked instructions placed inside the instruction manual placement rack 72 are in a state of being tilted toward the shuttle opening, ensuring that the instructions can pass through the discharge port smoothly under the drive of the feeding device 73.

[0100] Two sets of instruction manual shuttle wheel assemblies 74 are also arranged from top to bottom at the discharge port of the instruction manual placement rack 72, and a shuttle material gap is formed between the rims of the partition shuttle wheels in the two sets of instruction manual shuttle wheel assemblies 74 for the instruction manual to pass through, one end of the shuttle material gap is arranged corresponding to the discharge port of the instruction manual placement rack 72, and the other end of the shuttle material gap is arranged corresponding to the shuttle material port.

[0101] The instruction manual at the bottom is driven through the discharge port by the feeding device 73 until one end of the instruction manual enters the shuttle gap between the two shuttle wheel groups 74, and then the instruction manual is further delivered to the shuttle port by the rotation of the two instruction manual shuttle wheel groups 74. The instruction manual passes through the shuttle port and falls into the instruction manual receiving device 75 in a closed state. The above feeding steps are repeated until N instruction manuals are stored in the instruction manual receiving device 75, where N is equal to the number of gas meters placed in the packaging box. Then, the instruction manual receiving devices 75 on both sides are driven by the driving device 76 to slide or rotate away from each other, thereby opening the bottom of the shuttle port. At this time, N instruction manuals can fall into the packaging box at one time, completing the instruction manual placement operation.

One set of instruction manual shuttle wheel sets 74 is slidably arranged between the slide grooves on both sides, and another set of instruction manual shuttle wheel sets 74 is rotatably arranged between the mounting holes on both sides. By sliding the instruction manual shuttle wheel sets 74 installed between the slide grooves on both sides, the distance between the wheel rims of the two sets of instruction manual shuttle wheel sets 74 can be adjusted, thereby meeting the requirement of compatible transmission of instruction manuals of different thicknesses.

One end of the partition shuttle wheel shaft 741 of the instruction shuttle wheel set 74 passes through the slide groove on the mounting bracket 743 and is rotatably connected with the bearing hole on the bearing seat. An adjusting bolt is inserted between the adjusting hole and the adjusting groove. The adjusting bolt is slidably connected with the adjusting groove, and one end of the adjusting bolt extends to the outside of the adjusting groove and is threadedly installed with a clamping nut. Loosen the clamping nut, and then the adjusting bolt can slide vertically along the adjusting groove, thereby driving the bearing seat to slide vertically on the top side of the mounting bracket 743, thereby driving one group of partition shuttle wheel shafts 74 to slide vertically, thereby adjusting the distance between the two groups of instruction shuttle wheel sets 74. After the spacing adjustment is completed, the adjusting nut is tightened to achieve the positioning of the adjusting bolt, thereby achieving the positioning of one set of instruction manual shuttle wheel groups 74.

The material clamping and pushing device is a material clamping and pushing cylinder or a material clamping and pushing rod. The pushing end of the material clamping and pushing cylinder or the material clamping and pushing rod is connected to the side of the material clamping support 721 away from the shuttle material mouth. The material clamping and pushing cylinder or the material clamping and pushing rod drive the material clamping supports 721 on both sides to approach or move away from each other, thereby adjusting the distance between the material clamping supports 721 on both sides, thereby being compatible with limiting the instructions of different widths.

[0111] Further, such as Fig.12 and Fig.16As shown, the feeding device 73 includes a plurality of feeding wheel groups 731 that are rotatably arranged at the bottom of the inner side of the instruction manual placement rack 72 from high to low toward the shuttle opening, and a feeding driving device 732 that is transmission-connected to at least one of the feeding wheel groups 731; adjacent feeding wheel groups 731 are transmission-connected through any one of transmission gears, transmission belts, and transmission chains. The feeding wheel group 731 includes a feeding wheel shaft that is rotationally arranged at the bottom of the inner side of the instruction manual placement rack 72, and a plurality of feeding wheels that are axially sleeved on the feeding wheel shaft.

[0113] Furthermore, the feeding wheels on adjacent feeding wheel groups 731 are arranged at intervals along the axial direction, that is, the feeding wheels mounted on adjacent feeding wheel shafts are not arranged collinearly in the top view direction, thereby ensuring a larger contact area between the feeding wheels and the instruction manual.

[0114] Furthermore, a material pushing opening is provided on the side of the instruction manual placement rack 72 away from the shuttle material opening, and a material pushing device 78 is provided on the top of the shuttle material platform 71 corresponding to the material pushing opening and facing the shuttle material opening. Fig.17 As shown, the pushing device 78 includes a pushing cylinder 781 arranged along the length direction and a pushing plate 782 arranged at the end of the push rod of the pushing cylinder 781. The pushing cylinder 781 drives the pushing plate 782 to move toward the shuttle opening, thereby pushing the instruction manuals stacked inside the instruction manual placement rack 72 toward the shuttle opening, and cooperating with the feeding device 73 to feed the instruction manuals, so as to avoid the problem that the feeding device 73 cannot effectively transmit the instruction manuals when the stacked instruction manuals are large in number and heavy in weight.

[0115] Furthermore, an induction counter is provided at the discharge port of the instruction manual placement rack 72 close to the shuttle material port, and the number of instructions passing through the shuttle material port is counted by the sensor technology, thereby obtaining the number of instructions falling into the instruction manual receiving device 75.
