For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention discloses a pulling mechanism 140 for pulling a flexible belt through a delivery channel. The traction mechanism 140 includes a first suction block 141, a second suction block 142, and a negative pressure device (not shown). The negative pressure device is connected to the first and second adsorption blocks 141 and 142, respectively, so that the first or second adsorption blocks 141 or 142 can generate negative pressure to adsorb one end of the flexible belt 130, and the one end of the flexible belt 130 can move along with the first or second adsorption blocks 141 or 142 adsorbed thereto.
Further, the first suction block 141 is connected to a first driving device 143, and the first driving device 143 drives the first suction block 141 to move between the first position and the second position. The second adsorption block 142 is connected to a second driving device 144, and the second driving device 144 drives the second adsorption block 142 to move between the second position and the third position. The first position is located above the conveying channel, the second position is located in the conveying channel, and the third position is located below the conveying channel. That is, the first adsorption block 141 adsorbs the flexible belt by negative pressure to guide the flexible belt from the outside of the conveying passage to the inside of the conveying passage, and at the second position in the conveying passage, the first adsorption block 141 and the second adsorption block 142 are at least partially overlapped to separate the flexible belt from the first adsorption block 141, and the second adsorption block 142 adsorbs the flexible belt by negative pressure to replace the first adsorption block 141 to guide the flexible belt from the inside of the conveying passage to the outside of the conveying passage, so that the flexible belt penetrates from the upper side of the conveying passage to the lower side of the conveying passage. The first driving means 143 and the second driving means 144 are illustratively air cylinders.
With continued reference to fig. 1, specifically, the conveying channel includes an upper wall 211 and a lower wall 212, the upper wall 211 is provided with a first through notch 213, and the lower wall 212 is provided with a second through notch 214. The first driving device 143 is disposed above the upper wall 211, and the first adsorption block 141 penetrates the first gap 213 to move into the conveying channel (i.e. move between the first position and the second position). The second driving device 144 is disposed below the lower wall 212, and the second adsorption block 142 moves into the conveying channel (i.e. moves between the third position and the second position) through the second gap 214. Illustratively, the first drive 143 is mounted above the conveyor tunnel by a first mounting plate 146 and the second drive 144 is mounted below the conveyor tunnel by a second mounting plate 147.
Specifically, the direction of the flexible belt through the conveying path is perpendicular to or at an angle to the axial direction of the conveying path (i.e., the direction in which the articles flow) so that the flexible belt can receive the articles fed by the conveying path. Illustratively, the flexible belt extends through the transport path in a first direction (shown as X in fig. 1) and the articles flow in a second direction (shown as Y in fig. 1).
Further, the identification detection mechanism further includes a first pressure detector 153 and a second pressure detector 154. The first pressure detector 153 is used to detect whether the flexible belt is adsorbed by the first adsorption block 141. And a second pressure detector 154 for detecting whether the flexible belt is adsorbed by the second adsorption block 142. By the arrangement, the flexible belt can be ensured to be adsorbed by the first adsorption block 141 or the second adsorption block 142 and then move, and the traction effect is ensured. Specifically, when the flexible belt is adsorbed by the first adsorption block 141 or the second adsorption block 142, the negative pressure is large, whereas the negative pressure is small due to air leakage, whereby the air pressure of the first adsorption block 141 or the second adsorption block 142 can be detected by the pressure detector to determine whether the flexible belt is adsorbed.
According to the technical scheme, the traction mechanism 140 adopts a negative pressure adsorption mode to enable the flexible belt 130 to be adsorbed to the first adsorption block 141 or the second adsorption block 142, and can move along with the adsorption blocks, so that the adsorption structure is simple, and the space occupation of the traction mechanism 140 in a conveying channel is small. Meanwhile, the first adsorption block 141 and the second adsorption block 142 are adopted to replace the traction mode, and after the traction action of the first adsorption block 141 and the second adsorption block 142 is completed, the first adsorption block and the second adsorption block can move to the initial positions, so that the influence on the article conveying in the conveying channel is avoided.
The embodiment of the application also discloses a cigarette receiving and guiding device 100, which is arranged in a cigarette warehouse 200 of the packaging machine and is used for receiving and guiding cigarettes in the cigarette warehouse 200 when the packaging machine is started, wherein the cigarette warehouse 200 comprises a cigarette conveying channel, and the cigarettes are input into the cigarette warehouse 200 through the cigarette conveying channel. Referring to fig. 2 and 3, the cigarette receiving device 100 includes the traction mechanism 140, the flexible band 130, the flexible band support mechanism 120, the traction mechanism 140, and the identification detection mechanism described above.
Referring to fig. 4, flexible band 130 has a movable end 132 at one end and a fixed end 131 at the other end. Illustratively, flexible strip 130 is a BOPP cellophane tape of 0.2mm thickness, so configured, cost savings can be realized by using the remaining cellophane as flexible strip 130.
With continued reference to fig. 2, the flexible belt supporting mechanism 120 includes a paper winding roller 121, one end of the paper winding roller 121 is connected with a paper winding roller driving device 110, the other end of the paper winding roller 121 is rotatably connected with a paper winding roller 121 support, the paper winding roller 121 support provides support for the paper winding roller 121, and the paper winding roller driving device 110 can drive the paper winding roller 121 to rotate. The fixed end 131 of the flexible belt 130 is connected to the winding roller 121, and the flexible belt 130 is wound around the winding roller 121, and the winding roller driving device 110 is used for driving the winding roller 121 to rotate so as to unwind or wind the flexible belt 130 around the winding roller 121. The movable end 132 of the flexible belt 130 may be adsorbed to the first adsorption block 141 or the second adsorption block 142 to move with the adsorbed adsorption block. Wherein, the first adsorption block 141 can pull the flexible belt 130 to move from the first position to the second position, the second adsorption block 142 can pull one end of the flexible belt 130 to move from the second position to the third position, i.e. the movable end 132 of the flexible belt 130 is pulled by the pulling mechanism 140 along the direction shown by E in fig. 1 and 2, and penetrates the cigarette conveying channel.
Referring to fig. 3, a clamping means is further provided at the third position for fixing the movable end 132 of the flexible belt 130 when the second suction block 142 pulls the movable end 132 of the flexible belt 130 to the third position, fixing the movable end 132 of the flexible belt 130 with the fixed end 131, and a portion wound around the roll of paper 121 between the both ends is releasable to elongate a portion of the flexible belt 130 located in the conveyance path. That is, the flexible band 130 is blocked on the path of the inflow of the cigarettes, and one end of the flexible band 130 is fixed, so that when the cigarettes are input into the extrusion flexible band 130, one end of the flexible band 130 wound around the winding roller 121 is unwound and stretched to support the cigarettes extruded by the flexible band 130 to enter the cigarette warehouse 200 together, the flexible band 130 can adapt to the internal structure of the cigarette warehouse 200, and the supported cigarettes are moved to the set position of the cigarette warehouse 200.
Illustratively, the clamping device is disposed below the outside of the cigarette conveying channel, and the clamping jaw may be configured of two oppositely disposed cylinders, and after the two cylinders are ventilated, the moving ends extend to clamp the flexible belt 130.
Referring to fig. 2 and 3, a pressure roller 122 is disposed above the pack 200, the pressure roller 122 is disposed downstream of the paper winding roller 121, and is used to support the flexible belt 130, and the movable end 132 of the flexible belt 130 extends to the traction mechanism 140 through the pressure roller 122 so that it can be adsorbed by at least the first adsorption block 141. The pressure roller 122 is supported by a pressure roller support 122, and the pressure roller 122 is elastically coupled to the pressure roller support 122 so that the pressure roller 122 can move up and down with respect to the pressure roller support 122 as the pressure on the flexible belt 130 varies. Specifically, grooves extending along the first direction are formed at two ends of the support of the pressure roller 122, the elastic member 125 extending along the first direction is disposed in the grooves, one end of the elastic member 125 is connected with the support of the pressure roller 122, the other end is connected with the connecting end 1221 of the pressure roller 122, and the elastic members 125 at two ends form elastic support to the pressure roller 122 through the connecting ends 1221 at two ends of the pressure roller 122. Illustratively, the resilient member 125 is a spring.
Further, the identifying and detecting mechanism includes a distance sensor 151, where the distance sensor 151 is disposed near the pressure roller 122 and is used to detect the position change of the pressure roller 122, and the distance sensor 151 is electrically connected to the paper winding roller driving device 110 to perform timely feedback when the pressure roller 122 moves down or moves up after the pressure is relieved, so as to adjust the rotation speed of the paper winding roller driving device 110, and further adjust the unwinding speed of the flexible belt 130 to match the speed of the cigarette input.
Specifically, when a cigarette arrives at the packing machine magazine 200 from the upstream apparatus, and is fed into the magazine 200 by the cigarette feed channel, the cigarette will be blocked by the flexible belt 130, and the forward pushing force of the cigarette and the gravity of the cigarette will exert downward pressure on the flexible belt 130 (as shown by E in fig. 2), that is, downward pressure on the pressure roller 122 compresses the elastic member 125 and moves downward (as shown by E in fig. 2). After detecting the downward movement of the pressure roller, the distance sensor 151 sends an acceleration signal to the paper winding roller driving device 110 to accelerate the paper winding roller, so that the flexible belt 130 wound on the paper winding roller accelerates the unwinding, and the part of the flexible belt 130 located in the tobacco warehouse 200 is stretched to meet the storage capacity of cigarettes.
After the paper roll driving device 110 accelerates for a certain time, when the length of the flexible belt 130 in the cigarette warehouse 200 increases beyond a certain value, the pressure of the cigarettes on the flexible belt 130 decreases, and thus the pressure of the flexible belt 130 on the pressure roller 122 decreases, and the pressure roller is lifted up (i.e., moves in the direction shown in fig. 2D) by the elastic member 125. When the distance sensor 151 detects the upward movement of the pressure roller and transmits a signal for decelerating or stopping the operation to the roll paper driving device 110, the roll paper driving device 110 decelerates or stops, and the flexible belt 130 stops unreeling or slows down the unreeling speed. By the above, realize making the velocity of flow of cigarette and the speed phase-match of the loose reel of stock form roller drive arrangement 110 of mode with positive feedback, avoid flexible band 130 to loosen and roll up too fast and lead to the condition that the cigarette is messy or flexible band 130 is loosened and roll up too slow cigarette extrusion deformation to appear, guarantee the quality in the product traction process.
Further, referring to fig. 4, the flexible band 130 is provided with a first marking 133 indicating that the first marking 133 is in place, i.e., the first marking 133 is adjacent to the fixed end 131.
