Description

Technical Field

[0001] The invention relates to the technical field of cement packaging bag conveying, in particular to a conveyor for cement packaging bags with pasted bottoms. Background Art

[0002] At present, in order to realize the transportation of cement packaging bags during cement filling, it is usually necessary to use a conveyor to transport the cement packaging bags. The conveyor usually cooperates with the upstream cement packaging bag loading equipment and the downstream bag picking and delivering device to transport the cement packaging bags.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see the attached Figure 1 -Attached Figure 2 , a conveyor for cement packaging bags with glued bottom, comprising:

[0046] The vertical rack 1 has a rack leveling foot 8 at its bottom. The rack leveling foot 8 includes a foot adjustment plate 81, height adjustment studs 82 respectively inserted around the foot adjustment plate 81, and a foot fixing plate 83 connected to the height adjustment studs 82. By adjusting the rack leveling foot 8, the entire device can be adjusted to a level position to compensate for the defect that the installation surface may be uneven.

[0047] A sprocket chain assembly 2 is provided on the vertical frame 1, and the sprocket chain assembly 2 is driven by a driving device 3 provided on the vertical frame 1; the sprocket chain assembly 2 specifically includes sprocket shafts provided at the upper and lower ends of the vertical frame 1, sprockets provided at both ends of the sprocket shaft, and chains sleeved on the outer walls of the upper and lower sprockets;

[0048] The bag support frame assembly 4 is provided with a plurality of groups, and the plurality of groups of bag support frame assemblies 4 are equidistantly and movably arranged on the sprocket chain assembly 2, and are used to support the cement packaging bags with glued bottom;

[0049] There are two vertical guide components 5, which are symmetrically arranged at both ends of one side of the vertical frame 1;

[0050] There are two sets of arc guide components 6, which are symmetrically arranged at the upper and lower ends of the other side of the vertical frame 1; and

[0051] The bag taking and delivering assembly 7 is provided on one side of the vertical frame 1 and is used to deliver the cement packaging bag with the bottom paste on the bag supporting frame assembly 4 to the next device, such as the attached Figure 9 As shown, the bag taking and delivering assembly 7 includes a bag taking and delivering frame 71, a rotary bag delivering mechanism 72 provided on the bag taking and delivering frame 71, a rotary driving device 73 that drives the rotary bag delivering mechanism 72 to work, and a bag taking mechanism 74 provided on the bag taking and delivering frame 71. When the bag holding rack assembly 4 conveys the bottom-pasted cement packaging bag to a predetermined position on the bag taking side, the bag taking mechanism 74, the rotary bag delivering mechanism 72, and the rotary driving device 73 cooperate to take out the bottom-pasted cement packaging bag on the bag holding rack assembly 4 and deliver it to a downstream device in a certain direction. The bag delivery direction can be flexibly adjusted according to actual needs. The rotary bag delivering mechanism 72 and the bag taking mechanism 74 are both prior art and will not be described in detail here.

[0052] The vertical guide assembly 5 and the arc guide assembly 6 are used to ensure that the bag holding frame assembly 4 always maintains a horizontal state when it is driven by the sprocket chain assembly 2 .

[0053] When the conveyor is working, the driving device 3 causes the sprocket chain group 2 to drive the bag support frame assembly 4 along the attached Figure 2 It moves in the direction shown. When the bag holding rack assembly 4 reaches the predetermined position A on the bag placing side, the upstream equipment places the neatly stacked bottom-pasted cement packages on the bag holding rack assembly 4. The bag holding rack assembly 4 continues to move with the sprocket chain assembly 2 until it reaches the predetermined position B on the bag taking side. At this time, the bag taking and delivering assembly 7 transfers the packaging bags from the bag holding rack assembly 4 to the downstream equipment in a specific direction.

[0054] Because the cement packaging bags with pasted bottoms are light and soft in texture, during operation, in order to prevent the cement packaging bags with pasted bottoms from relative sliding, position displacement and bag deformation on the bag holding rack assembly 4, the vertical guide assembly 5 and the arc guide assembly 6 are arranged to cooperate with the bag holding rack assembly 4, so that the bag holding rack assembly 4 is not affected by the vibration generated by the machine itself and the outside, as well as the external operating force applied during the bag placing and taking process, and always maintains a stable horizontal state.

[0055] Please refer to the attached figure 3 - Figure 4 As a preference, the bag holding rack assembly 4 of this embodiment includes a bag holding rack 41, a panel 42 provided on the bag holding rack 41, a limit baffle 43 provided on the panel 42 at one end away from the bag taking and delivering assembly 7, two sets of side baffles 44 respectively provided on the bag holding rack 41 and located on the outside of the panel 42, two sets of hanging plates 45 respectively provided at both ends of the bag holding rack 41, a shaft 46 provided on the hanging plate 45, and a bag holding cantilever 47 connected to the shaft 46 through a diamond seat bearing 48. One end of the bag holding cantilever 47 The end is connected to the sprocket chain group 2, and the bottom cement packaging bags on the bag holding rack 41 are limited from the tail end, valve end and side of the bottom cement packaging through the limiting baffle 43 and two sets of side baffles 44. It should be noted that the limiting baffle 43 and the panel 42, the side baffle 44 and the bag holding rack 41 can be detachably connected to adjust the use position according to actual usage. The limiting baffle 43 cooperates with the upstream equipment to push and block the stack of packaging bags, so that the stack of bottom cement packaging can be neatly stacked;

[0056] An X-shaped guide frame 49 is provided at one end of the shaft body 46 facing the vertical guide assembly 5, and guide wheels 411 are rotatably provided at all four ends of the X-shaped guide frame 49. A T-shaped guide frame 410 is provided at one end of the shaft body 46 facing the arc guide assembly 6, and guide wheels 412 are rotatably provided at both ends of the T-shaped guide frame 410. A position detection plate 413 is provided at one end of the T-shaped guide frame 410 facing the bag picking and delivering assembly 7, which cooperates with an external proximity sensor to detect the position of the bag holding frame assembly 4 in real time.

[0057] Please refer to Figure 6 - Attachment Figure 7 Preferably, the vertical guide assembly 5 of this embodiment includes a vertical guide rail 52 connected to the vertical frame 1 through a mounting frame 51 and a buffer arc 53 integrally provided at both ends of the vertical guide rail 52;

[0058] The vertical guide rail 52 is used to contact the two guide wheels 411 in the vertical direction of the X-shaped guide frame 49 when the bag holding rack assembly 4 runs to the vertical section path through the sprocket chain group 2. Through this arrangement, it is possible to prevent the external operating force, shaking and vibration from affecting the posture of the bag holding rack 41, avoid the deflection and swing of the bag holding rack 41 during movement, and always keep the bag holding rack 41 in a stable horizontal state, ensuring that the packaging bags placed on the upper surface of the bag holding rack 41 do not produce relative sliding, position displacement and bag body deformation. By setting a buffer arc 53, it can play a transition role when the guide wheel 411 begins to fit into and separate from the vertical guide rail 52, thereby effectively alleviating the impact.

[0059] Preferably, the arc guide assembly 6 of this embodiment includes a mounting plate 61 provided in the vertical frame 1, two sets of non-concentric arc guide rails 62 provided on the side of the mounting plate 61 facing the second guide wheel 412, and a second buffer arc 63 integrally provided at both ends of the arc guide rails 62;

[0060] The two sets of non-concentric circular arc guide rails 62 are used to contact the two guide wheels 412 respectively when the bag holding rack assembly 4 runs through the sprocket chain group 2 to the upper and lower circular arc segment paths (chain and sprocket meshing segments). Since the movement direction of the bag holding rack assembly 4 changes at this time, the two guide wheels 412 roll along the double circular arc guide rails 62 respectively, and the bag holding rack 41 can always be kept in a stable horizontal state while the movement direction of the bag holding rack assembly 4 changes.

[0061] Example 2

[0062] Since the bag support frame 41 is in a free state during the transition from the vertical section to the arc section or from the arc section to the vertical section, when the bag support frame assembly 4 has uneven mass distribution, the bag support frame 41 may tilt, resulting in unstable transition transportation. To prevent this situation, please refer to the attached Figure 7 -Attached Figure 8 , the present application is provided with a horizontal self-regulating component 9 at the bottom of the bag holding frame component 4, and the horizontal self-regulating component 9 includes a counterweight regulating part provided at the bottom of the bag holding frame 41 and a detection part provided on the bag holding cantilever 47;

[0063] The counterweight control part is used to drive the bag holding rack assembly 4 to restore to a horizontal state when the detection part detects that the bag holding rack assembly 4 is tilted. The center of gravity of the bag holding rack assembly 4 is adjusted to the geometric center through the cooperation of the counterweight control part and the detection part to ensure that the free state of the bag holding rack 41 can also be stably maintained horizontal during the transition process from the vertical section to the circular arc section.

[0064] Preferably, the counterweight control portion of this embodiment includes a mounting seat 91 detachably provided at the center of the bottom of the bag holding rack 41, two sets of rectangular sleeves 92 movably inserted at both ends of the mounting seat 91, and two sets of adjusting screws 93 threadedly inserted at both ends of the rectangular sleeve 92. The other end of the adjusting screw 93 located inside the rectangular sleeve 92 is connected to a micro-rotating device, and the other end of the adjusting screw 93 located outside the rectangular sleeve 92 is rotatably connected to a counterweight block 94. The two sets of counterweight blocks 94 are slidably provided on both sides of the bottom of the bag holding rack 41.

[0065] The axes of the rectangular sleeve 92 and the adjusting screw 93 extend along the width direction of the panel 42;

[0066] The inner adjusting screw 93 is driven by a micro-rotating device so that the rectangular sleeve 92 drives the outer adjusting screw 93 and the counterweight 94 to move relative to the mounting seat 91, thereby changing the position of the counterweight 94 at the bottom of the bag holding rack 41; it should be noted that the rectangular sleeve 92 is rectangular, so it will not be driven by the adjusting screw 93 to rotate relative to the mounting seat 91. At the same time, the user can also manually rotate the outer adjusting screw 93 to rotate and change the position of the counterweight 94.

[0067] Preferably, the detection portion of this embodiment includes an annular shell 95 fixed to the bag holding cantilever 47 and movably sleeved on the shaft 46, a calibration protrusion 97 integrally provided on the calibration seat 96, and two sets of arc springs 98 respectively connected to both sides of the calibration protrusion 97, the other end of the arc spring 98 is connected to a pressure sensor 99 fixed in the annular shell 95, the pressure sensor 99 is electrically connected to a power supply device and a single-chip microcomputer provided in the inner cavity of a protective shell 910 on the mounting seat 91, and the power supply device and the single-chip microcomputer are also electrically connected to a micro-rotating device. The pressure sensor 99 belongs to the prior art, and its model is selected according to actual conditions. It is not described in detail here. When the two pressure sensors 99 do not receive a pressure signal, it indicates that the bag holding frame 41 is in a horizontal state;

[0068] The pressure sensor 99 on one side is used to receive the pressure signal of the arc spring 98 when the calibration seat 96 rotates clockwise with the shaft body 46 and send the pressure signal to the single chip microcomputer, so that the single chip microcomputer controls the micro rotating device used to drive the counterweight block 94 close to the limit stopper 43 to move;

[0069] The pressure sensor 99 on the other side is used to receive the pressure signal of the arc spring 98 when the calibration seat 96 rotates counterclockwise with the shaft body 46 and send the pressure signal to the single-chip microcomputer, so that the single-chip microcomputer controls the micro-rotating device used to drive the counterweight block 94 away from the limit stopper 43 to move;

[0070] Among them, the micro rotating equipment includes micro motors and micro reducers.

[0071] For example, from the attached Figure 7 It can be seen that when the pressure sensor 99 on the right receives a pressure signal, it indicates that the bag holding rack 41 is tilted to the right. At this time, the single-chip microcomputer controls the micro-rotating device in the opposite direction to drive the corresponding counterweight block 94 to move toward the outer end of the bag holding rack 41, thereby restoring the bag holding rack 41 to a horizontal state; the same applies when the pressure sensor 99 on the left receives a pressure signal.

[0072] Because the bag holding rack 41 has no obstruction relative to one end of the limit baffle 43, the cement bags with glued bottoms will be displaced when the bag holding rack 41 tilts downward relative to one end of the limit baffle 43. In order to solve this problem, as a preferred embodiment, the horizontal self-regulating component 9 of this embodiment also includes an anti-drop adjustment component, which includes a movable frame 912 movably arranged on the mounting seat 91 through a guide rail, a driving part for driving the movable frame 912 to move, a T-shaped guide rod 916 horizontally arranged on the mounting seat 91, and a movable sleeve. A U-shaped seat 917 is provided at one end of the guide rod 916 away from the mounting seat 91; a return spring 911 is provided on the guide rod 916 for limiting the movement of the U-shaped seat 917; a rotating shaft provided in the U-shaped seat 917 is rotated by a torsion spring and a bearing; a plurality of movable baffles 918 are provided on the outer wall of the rotating shaft; an L-shaped limiting member 919 is provided on the U-shaped seat 917 and is used to limit the movable baffles 918 from turning to a vertical state; and a linkage portion is provided on the mounting seat 91 and is driven by the movable frame 912. The U-shaped seat 917 is located at one end below the bag holding frame 41 relative to the limiting baffle 43;

[0073] The driving unit is controlled by the single chip microcomputer to drive the moving frame 912 to move. When the moving frame 912 moves, the linkage unit drives the rotating shaft to drive the moving baffle 918 to flip until it contacts the L-shaped limit member 919 and then drives the U-shaped seat 917 to move along the guide rod 916 toward the limit baffle 43.

[0074] It should be noted that when the movable baffle 918 is flipped to the vertical state, it is opposite to the limiting baffle 43 and has the same height as the limiting baffle 43 .

[0075] Preferably, the driving unit of this embodiment includes an electromagnetic block 914 provided on the mounting base 91, a permanent magnet block 921 provided on the outer wall of the movable frame 912 on the side opposite to the electromagnetic block 914, and a tension spring 913 having one end connected to the movable frame 912 and the other end connected to a protrusion fixed to the mounting base 91.

[0076] The electromagnetic block 914 is electrically connected to the microcontroller. When a pressure sensor 99 is connected to the microcontroller to control the micro-rotating device for driving the counterweight block 94 near the limit baffle 43 to move, the electromagnetic block 914 is also energized. The electromagnetic block 914 is energized to attract the permanent magnet block 921, thereby moving the movable frame 912. After the electromagnetic block 914 is powered off, the tension spring 913 drives the movable frame 912 to reset. Figure 7 -Attached Figure 8 It can be seen that the operation of the micro-rotating device that drives the counterweight 94 near the limiting baffle 43 indicates that the bag holding frame 41 is tilted downward relative to one end of the limiting baffle 43 .

[0077] Preferably, the linkage part of this embodiment includes a driving gear arranged on the mounting seat 91 through a rotating shaft, a winding roller 915 arranged on one side of the driving gear and coaxial with it, and a rack arranged on the movable frame 912 for engaging with the driving gear. One end of a pull rope 920 is wound around the outer wall of the winding roller 915, and the other end of the pull rope 920 is wound around the outer wall of the rotating shaft.

[0078] When the movable frame 912 moves, the driving gear is driven by the rack, and the driving gear causes the winding roller 915 to reel in the pull rope 920, and then the pull rope 920 first drives the rotating shaft to rotate so that the movable baffle 918 is flipped to a vertical state to limit it to prevent the cement packaging bag on the bag holding rack 41 from sliding from the other end when tilted. On the other hand, after the movable baffle 918 is flipped to a vertical state, it contacts the L-shaped limit piece 919 and cannot continue to flip, while the pull rope 920 continues to be reeled in. At this time, the pull rope 920 will pull the rotating shaft to make the U-shaped seat 917 move toward the limit baffle 43. The U-shaped seat 917 moves and pushes the cement packaging bag on the bag holding rack 41 through the movable baffle 918 flipped to a vertical state, helping the cement packaging bag to return to a neat posture when it is horizontal.

[0079] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
