Description

Technical Field

[0001] The present invention relates to the technical field of tobacco logistics equipment, and in particular to an automatic cigarette pack stacking system. Background Art

[0002] Among the existing cigarette pack palletizing equipment, there are palletizing equipment for special-shaped cigarette packs, including robot palletizing and truss-type palletizing. Although the palletizing process of standard cigarette packs is not as complicated as that of special-shaped cigarette packs, although the length and width of cigarette packs are certain, the number of layers of cigarette strips in each cigarette pack may be different, so the thickness of each cigarette pack may vary. It is very difficult for ordinary palletizing equipment to put all the continuously arriving cigarette packs into the stacking cage and fill the entire stacking cage space.

[0003] In order to maximize the space utilization of the stacking cage, some use a mechanism to push the cigarette packs directly to the buffer zone, and the cigarette packs are manually placed in the appropriate position in the stacking cage. Although this method saves most of the manual work, it also requires the operator to keep an eye on the work site and deal with the cigarette packs in the buffer zone in time, so it has limited effect in saving manpower. Although the robot standard cigarette pack palletizing based on machine vision can perform 3D palletizing based on the collected cigarette pack images, it is difficult for the robot palletizing to adapt to the high-speed beat requirements of the tobacco logistics industry.

The main conveying belt 11 and the turnover mechanism 13 are both installed on the conveying frame 14. The position on the main conveying belt 11 is the conveying area. The cigarette packs are conveyed to the sorting assembly 3 in the conveying area. The turnover mechanism 13 is arranged at one end of the main conveying belt 11 in the length direction (the end of the main conveying belt 11 close to the sorting assembly 3). Figure 2As shown, the flipping mechanism 13 is driven by a servo motor. The flipping mechanism 13 includes a first motor 133, a flipping shaft 131 and a rotating disk 132. Two rotating disks 132 are provided. The two rotating disks 132 are both sleeved on the flipping shaft 131. The first motor 133 is provided on the conveying frame 14. The output end of the flipping shaft 131 is connected to the output end of the first motor 133. The axis of the flipping shaft 131 is perpendicular to the running direction of the main conveyor belt 11. The rotating disk 132 is provided with a notch every 120° along the circumferential direction. The angle between the two side walls of the notch is 90°. The first motor 133 can drive the rotating disk 132 to rotate through the flipping shaft 131. Through the rotation of the rotating disk 132, the flipping mechanism 13 can flip the cigarette pack conveyed by the main conveyor belt 11 by 90°, and the height of the cigarette pack after flipping is the same; the main conveyor belt 11 is The roller conveyor belt driven by chain transmission, the main conveyor belt 11 includes a second motor 115, a plurality of long rollers 111 and a short roller 112, the plurality of long rollers 111 are evenly distributed in the length direction of the main conveyor belt 11, the ends of the plurality of long rollers 111 are staggeredly connected by gears and chains, the second motor 115 is arranged on the conveying frame 14, two adjacent long rollers are connected by a chain, the output end of the second motor 115 is connected to a long roller by a chain, the short roller 112 is arranged between two rotating disks 132, the short roller 112 and the adjacent long roller 111 are connected by a belt 113, one end of the main conveyor belt 11 (the end of the main conveyor belt 11 with the short roller 112) is embedded between the two rotating disks 132, to ensure that the cigarette pack has enough power to reach the notch end face of the rotating disk 132. The conveying assembly 1 conveys the cigarette packs conveyed from the packaging machine to the sorting assembly 3, and before conveying into the sorting assembly 3, the cigarette packs are turned over by the flipping mechanism 13, and the turned cigarette packs enter the sorting assembly 3 for sorting. Since the width of the cigarette packs is the same, the height of each cigarette pack in a row formed by flipping multiple cigarette packs 90 degrees is the same, so that the top layer of the entire layer of cigarette packs stacked in the stacking cage trolley 5 is a plane, which makes the cigarette packs more stable in the stacking cage trolley 5, ensuring that the cigarette packs will not be displaced during transportation, thereby preventing the cigarette packs from being damaged.

[0029] Furthermore, the conveying assembly 1 also includes an auxiliary conveyor belt 12, which is located on one side of the main conveyor belt 11. The auxiliary conveyor belt 12 is an unpowered roller conveyor belt.

When the cigarette packs to be palletized are delivered to the front end of the conveying component 1, the thickness measuring component 2 collects the thickness information of the cigarette packs at the current position and passes the thickness value of the cigarette packs as input into the pack selection strategy algorithm.

[0039] Specifically, the method for obtaining the thickness of the cigarette pack is as follows: when the cigarette pack to be stacked is conveyed to the bottom of the laser ranging sensor 23 at the front end of the conveying component 1, six laser ranging sensors 23 arranged in parallel respectively obtain the measurement value of the current position. Since the number of cigarette strips in the top layer of the cigarette pack is not a multiple of 5 (except the top layer, the number of cigarette strips in other layers of the cigarette pack is a multiple of 5), the upper surface of the cigarette pack is not a plane, and the maximum value of the six thickness values ​​is the thickness of the current cigarette pack.

[0040] S2. Select the best cigarette pack based on the pack selection strategy according to the current cigarette pack thickness, the number and thickness of the cigarette packs in the buffer zone, and the length of a row of cigarette packs being sorted in the sorting area.

[0041] Specifically, since the size of the stacking cage 5 for stacking cigarette packs is fixed, the stacking assembly 4 arranges the cigarette packs into two rows of cigarette packs that are not longer than the length of the stacking cage 5 and puts them into the stacking cage 5 as one layer. Therefore, the pack selection strategy is to select the cigarette pack with the largest thickness from the buffer area and the current cigarette packs each time, on the premise that the pack is not longer than the length of the stacking cage 5, and then put it on the main conveyor belt 11, flip it, and then enter the row cigarette pack sorting area.

[0042] S3, sending the cigarette packs selected according to the pack selection strategy to the turning mechanism 13, and adding them to the row of cigarette packs currently being sorted.

[0043] Specifically, two methods are adopted according to the different positions of the cigarette packages selected by the package selection strategy. First, when the cigarette package selected by the package selection strategy is a cigarette package that has just entered the main conveyor belt 11, the cigarette package is directly transported to the position of the flipping mechanism 13 for flipping; second, when the cigarette package selected by the package selection strategy is a cigarette package in the buffer zone, a group of first push plates 15 corresponding to the cigarette package in the corresponding buffer zone moves the cigarette package to the main conveyor belt 11, and then transports the cigarette package to the position of the flipping mechanism 13 for flipping.

[0044] S4. When the thickness of the cigarette packs delivered by the packaging machine does not meet the requirements of the pack selection strategy, the cigarette packs delivered by the packaging machine are placed in the buffer as candidate cigarette packs to participate in the next cigarette pack selection.

[0045] Specifically, the current states of the three buffers are traversed from right to left, and the current cigarette packet is placed into one of the empty buffers. The specific steps are as follows:

[0046] S41, opening the fourth baffle 114 corresponding to the empty buffer zone, and the first cylinder drives the fourth baffle 114 to extend from between the long rollers 111 of the main conveyor belt 11 to a certain height above the plane of the main conveyor belt 11.

[0047] S42, when the photoelectric switch detects that the cigarette pack has arrived, the corresponding group of first push plates 15 moves the cigarette pack into the buffer zone under the drive of the third motor 151.

[0048] S43, closing the fourth baffle 114, and the first cylinder drives the fourth baffle 114 to descend below the plane of the main conveyor belt 11.

[0049] S5. After the cigarette packs reach the flipping mechanism 13, the flipping mechanism 13 flips the cigarette packs 90 degrees so that the heights of each cigarette pack are consistent after flipping.

[0050] S6. Put the turned cigarette pack into the current row of cigarette packs. According to the current cigarette pack thickness, the row conveyor belt 32 moves the distance of the current cigarette pack thickness, and the anti-dumping mechanism 33 places the second baffle 333 behind the cigarette pack to prevent the cigarette pack from dumping. When arranging the first cigarette pack in a row, the initial position of the first baffle 35 is close to the turning mechanism 13, and the row conveyor belt 32 is first driven to move the distance of the current cigarette pack thickness, and the first baffle 35 moves synchronously with the row conveyor belt 32 to leave space for the turned cigarette pack.

[0051] The specific steps are:

[0052] S61. According to the current cigarette pack thickness, the conveyor belt 32 moves a distance corresponding to the current cigarette pack thickness.

[0053] S62: After the cigarette pack is turned over, the second cylinder 332 is closed and the second baffle 333 moves upward.

[0054] S63 , the ball screw 331 driven by the fifth motor 334 drives the second baffle 333 to move to the vicinity of the rotating disk 132 of the turning mechanism 13 .

[0055] S64, opening the second cylinder 332, so that the second baffle 333 moves downward to block the cigarette pack behind to prevent the cigarette pack from falling over.

[0056] S65. Repeat steps S61 to S64 until a row of cigarette packs is formed on the row conveyor belt 32. The sorting component 3 pushes the sorted row of cigarette packs into the layer stacking platform 432. When the sorting component 3 pushes two rows of cigarette packs into the layer stacking platform 432, the sorting of a whole layer of cigarette packs is completed. The clamping mechanism 433 descends and presses on the upper surface of the whole layer of cigarette packs.

[0057] S7, stack the whole layer of cigarette packs to a specified height in the stacking cage vehicle 5. According to the specific situation of the cigarette packs stacked in the stacking cage vehicle 5, the specific steps are as follows:

[0058] S71. According to the height of the upper surface of the cigarette packs in the current stacking cage vehicle 5, the lifting mechanism 42 moves the platform lifting plate 423 to a height above the upper surface of the existing cigarette packs in the stacking cage vehicle 5.

[0059] S72, the telescopic member 431 is moved to drive the layer stacking platform 432 to extend into the stacking cage vehicle 5.

[0060] S73, the clamping mechanism 433 rises to release the compressed cigarette pack.

[0061] S74, open the third cylinder 434 to move the third baffle 435 downward, and block the third baffle 435 on a side of a layer of cigarette packs close to the palletizing assembly 4.

[0062] S75 , the mobile telescopic member 431 moves backward into the layer stacking platform 432 , so that the cigarette packs in the layer stacking platform 432 naturally fall into the stacking cage vehicle 5 .

[0063] S76: The lifting mechanism 42 moves to the initial position and waits for the next layer of cigarette packs.

[0064] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0065] An automatic cigarette pack stacking system is disclosed. The stacking system utilizes a pack selection strategy in combination with a stacking algorithm to automatically sort standard cigarette packs and stack them in a stacking cage trolley 5, thereby filling up the space of the stacking cage trolley 5 to the greatest extent, maximizing the space utilization of the stacking cage trolley 5, maintaining the stability of the cigarette packs in the stacking cage trolley 5, and preventing the cigarette packs from shaking in the stacking cage trolley 5 and colliding with the wall of the stacking cage trolley 5 to damage the cigarette packs.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
