[0032] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0033] The carton sealing machine in the related art adopts a swing-rod type arrival detection device to detect whether the cigarette box has reached the set grabbing position.
[0034] like Figure 1 and Figure 2 As shown, the swing rod type in-place detection device 100 includes a swing rod 101, a washer 102, a counterweight 103, a stop ring 104, a detector bracket 105, a detector, a copper sleeve 106, and a fixed plate 107. Along the conveying direction of the cigarette box, the detector bracket 105, the swing rod 101 and the stop ring 104 are sequentially arranged on the fixed plate 107. In addition, the fixed plate 107 is installed on the side plate 108 of the conveyor belt. Among them, the detector bracket 105 is used to install a capacitive detector. The swing rod 101 is connected to the counterweight 103, and the swing rod 101 can drive the counterweight to rotate together. The stop ring 104 is used to stop the swing rod 101 from swinging by contacting the swing rod 101 during the movement of the swing rod 101. The swing rod 101 and the stop ring 104 can be fixed to the fixed plate 107 by bolts or screws. In addition, a washer 102 is provided between the rocker arm 101 and the bolt (or screw), and a copper sleeve 106 is provided between the rocker arm 101 and the fixing plate 107 .
[0035] like Figure 3 As shown, the cigarette box warehouse is used to store cigarette boxes 200, and can transport cigarette boxes 200 through a conveyor belt 303. The swing-rod type in-place detection device 100 is installed between the conveyor belt 303 and the side baffle 302 of the cigarette box warehouse.
[0036] The detection principle of the swing rod type in-place detection device is as follows: the cigarette box is conveyed forward under the drive of the conveyor belt. When the Nth cigarette box contacts the swing rod 101, the swing rod 101 is pushed to rotate forward, thereby driving the counterweight block 103 to rotate, so that the counterweight block 103 enters the detection range of the capacitance detector. When the counterweight block 103 enters the detection range of the capacitance detector, the capacitance detector detects the counterweight block, and then under the control of the controller, the conveyor belt is driven by the motor to stop moving, so that the Nth cigarette box stops conveying forward. Then, the cigarette box forming device grabs the Nth cigarette box for opening and forming operations. After the cigarette box forming device grabs the Nth cigarette box, the swing rod 101 drives the counterweight block back to the original position, and the capacitance detector cannot detect the counterweight block. Then, under the control of the controller, the conveyor belt is driven by the motor to continue to move, so that the N+1th cigarette box contacts the swing rod. When the capacitance detector detects the counterweight block, the conveyor belt is driven by the motor to stop moving, so that the N+1th cigarette box stops conveying forward. Then, the cigarette box forming device grabs the N+1th cigarette box to perform an opening and forming operation, wherein N is an integer greater than or equal to 1.
[0037] The swing-rod in-place detection device in the related art has the following problems: First, the swing-rod in-place detection device indirectly detects whether the cigarette box is in place by detecting the counterweight block, and its detection accuracy is insufficient, which affects the grasping accuracy and grasping efficiency of the cigarette box in the carton sealing machine; second, the installation space of the swing-rod in-place detection device is small and difficult to adjust, making it difficult to adjust the detector to a precise position; third, the copper sleeve in the swing-rod in-place detection device is easy to wear, and the screw that fixes the stop ring is easy to break, which easily causes equipment failure. All of the above factors affect the overall operating efficiency of the carton sealing machine.
[0038] In view of this, the present disclosure proposes a cigarette box conveying device. Figure 4 and Figure 5 The conveying device of the cigarette box in the embodiment of the present disclosure is exemplified.
[0039] like Figure 4 As shown, the conveying device of the cigarette box includes two conveyor belts, a first optical fiber detector 400, a second optical fiber detector 500, a first motor, a second motor and a controller.
[0040] Two conveyor belts, including conveyor belt 303 and conveyor belt 304, are used to transport cigarette boxes in the cigarette box warehouse. Exemplarily, the conveyor belts are specifically synchronous belts.
[0041] The first optical fiber detector 400 is fixed to the side plate 301 of the conveyor belt 303 through a first mounting bracket, and is used to detect whether the cigarette box reaches the set grabbing position.
[0042] The second optical fiber detector 500 is fixed to the side plate of the conveyor belt 304 through a second mounting bracket, and is used to detect whether the cigarette box reaches the set grabbing position.
[0043] In some examples, the first fiber optic detector 400 and the second fiber optic detector 500 are arranged between two conveyor belts. By such arrangement, compared with arranging the fiber optic detector between the conveyor belt and the side baffle of the cigarette box warehouse, the accommodation space of the fiber optic detector is increased, making the fiber optic detector easy to adjust.
[0044] In some examples, the first optical fiber detector 400 and the second optical fiber detector 500 are installed at the same height and at the same installation position along the set direction, which is the running direction of the conveyor belt. By setting it in this way, the cigarette box detection positions corresponding to the two optical fiber detectors are close to each other, so that the distances between the left and right sides of the cigarette box and the main suction arm of the cigarette box forming device are close when the cigarette box stops moving, which is convenient for the main suction arm to grab the cigarette box.
[0045] In some examples, in addition to the above positional relationship, the first fiber optic detector 400 and the second fiber optic detector 500 also satisfy: the angle between the light emitted by the first fiber optic detector 400 and the horizontal plane is the same as the angle between the light emitted by the second fiber optic detector 500 and the horizontal plane.
[0046] For example, the light emitted by the first optical fiber detector 400 and the light emitted by the second optical fiber detector 500 are both tilted upward at a certain angle relative to the horizontal plane, so that when the cigarette box reaches the set position, the light is irradiated on the bottom of the cigarette box, and then the light shielding signal caused by the cigarette box is detected. Before this, the light emitted by the first optical fiber detector 400 and the second optical fiber detector does not shine on the cigarette box, so that they cannot detect the cigarette box.
[0047] Figure 5 The schematic diagram of the structure of the optical fiber detector and its mounting bracket is shown. Figure 5 As shown, the first optical fiber detector 400 is mounted on a first mounting bracket 410. The first mounting bracket 410 includes a first mounting groove 411 and a second mounting groove 412. The first optical fiber detector 400 is fixed to the first mounting groove by a nut. The first mounting bracket 410 is fixed to the side plate of the conveyor belt by the second mounting groove 412. The second mounting bracket has the same structure as the first mounting bracket.
[0048] In a specific implementation, the position of the optical fiber detector 400 in the first installation slot and the position of the nut and other firmware components in the second installation slot can be adjusted to adjust the detection position of the optical fiber detector corresponding to the cigarette box, thereby helping to improve the accuracy of cigarette box detection and grasping. In addition, in a specific implementation, in order to improve the sensitivity of in-place detection, an amplifier 420 used in conjunction with the optical fiber detector is also provided.
[0049] In some embodiments, a distance scale may be provided on the first mounting bracket and the second mounting bracket. For example, a distance scale may be added beside the first mounting slot of the first mounting bracket and the second mounting slot. The distance scale may be set to millimeter level, and the minimum value may be set to 1 mm. By providing a distance scale, it is convenient to adjust the distance between the detector and the smoke box. In addition, an angle scale may be provided on the first mounting bracket. By providing an angle scale, it is not only convenient to display the installation angle of the mounting bracket, but also convenient to adjust the installation angle of the mounting bracket.
[0050] The first motor is used to drive the conveyor belt 303 to stop running under the control of the controller when the first optical fiber detector 400 detects that the cigarette box 200 reaches the set grabbing position.
[0051] The second motor is used to drive the conveyor belt 304 to stop running under the control of the controller when the second optical fiber detector 500 detects that the cigarette box 200 reaches the set grabbing position, so that the cigarette box forming device can grab the cigarette box 200.
[0052] For example, when the first optical fiber detector detects a cigarette box, under the control of the controller, the conveyor belt 303 is immediately stopped by the motor drive so that the main suction arm can grab the cigarette box. When the first optical fiber detector does not detect a cigarette box on the conveyor belt, the motor drive conveyor belt is controlled to run after a delay of t seconds (for example, 1 second) to transport the next cigarette box forward.
[0053] For example, when the second optical fiber detector detects a cigarette box, under the control of the controller, the conveyor belt 304 is immediately stopped by the motor drive so that the main suction arm can grab the cigarette box. When the second optical fiber detector does not detect a cigarette box on the conveyor belt, the motor drive conveyor belt is controlled to run after a delay of t seconds (for example, 1 second) to transport the next cigarette box forward.
[0054] In some embodiments, the cigarette box conveying device further comprises a blocking rod, which is arranged above the cigarette box storehouse and is used to fix the cigarette box in a height direction along the cigarette box.
[0055] For example, Figure 4 As shown, the baffle rod includes a first baffle rod 305 and a second baffle rod 306. The first baffle rod 305 is installed on one baffle plate of the two side baffle plates of the cigarette box warehouse, and the second baffle rod 306 is installed on the other baffle plate of the two side baffle plates of the cigarette box warehouse. In addition, the first baffle rod and the second baffle rod are both provided with an adjustment screw for adjusting the installation height. By arranging the first baffle rod and the second baffle rod in the conveying device of the cigarette box, it is convenient to fix the cigarette box in the height direction of the cigarette box warehouse, prevent the cigarette box from falling, and improve the stability of the cigarette box conveying. Further, by arranging the adjustment screw in the first baffle rod and the second baffle rod, it is convenient to adjust the installation height of the baffle rod, so that it can be used to fix cigarette boxes of different heights, thereby improving the applicability of the conveying device of the cigarette box.
[0056] In some examples, the blocking rod is further designed to have a cylindrical roller that can rotate freely at one end. In this way, when the cylindrical roller of the blocking rod contacts the cigarette box, it can play a certain fixing role without damaging the cigarette box. In addition, in specific implementation, the contact area between the cylindrical roller of the blocking rod and the cigarette box can be adjusted by adjusting the installation height of the blocking rod, thereby preventing the cigarette box from falling and reducing the damage to the cigarette box.
[0057] In some embodiments, the conveying device of the cigarette box further includes a width adjustment device. The width adjustment device 307 is used to adjust the distance between the baffles on both sides of the cigarette box storehouse. For example, a handle is provided on the width adjustment device 307 so that the width of the cigarette box storehouse can be adjusted by shaking the handle. Through the above arrangement, not only the cigarette box storehouse can adapt to cigarette boxes of different specifications, but also the cigarette boxes will not be clamped too tightly in the cigarette box storehouse, so that the cigarette boxes on the conveyor belt move more smoothly, and the operation efficiency of the case sealing machine is improved.
[0058] In the embodiment of the present disclosure, through the above-mentioned cigarette box conveying device, at least one of the following technical effects can be achieved: first, by respectively arranging optical fiber detectors on the side plates of each of the two conveyor belts, using optical fiber sensors to directly detect cigarette boxes, and controlling the corresponding conveyor belts to stop running when the cigarette boxes are detected, so that the cigarette box forming device can grab the cigarette boxes, compared with indirectly detecting the cigarette boxes using a swing-bar type in-place detection device, the in-place detection accuracy of the cigarette boxes can be improved, thereby improving the grabbing accuracy and efficiency of the cigarette boxes; second, by arranging the optical fiber detector between the two conveyor belts, compared with arranging it between the conveyor belt and the side baffle of the cigarette box warehouse, the accommodating space of the detector is increased, making the detector easy to adjust; third, the detector and its mounting bracket in the conveying device of the cigarette box disclosed in the present disclosure have a simple structure. The combination of the above factors can improve the operating efficiency of the carton sealing machine.
[0059] like Figure 6 As shown, the present disclosure further proposes a carton sealing machine 600. The carton sealing machine 600 comprises a cigarette box conveying device 601. The cigarette box conveying device 601 may adopt the structure as described above.
[0060] In the embodiment of the present disclosure, by including the cigarette box conveying device 601 as shown above in the carton sealing machine, the operating efficiency of the carton sealing machine can be improved and the failure rate of the equipment can be reduced.
[0061] So far, the conveying device and the case sealing machine of the cigarette box according to the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.
