Description

Technical Field

[0001] The present invention relates to the field of tobacco, in particular to a self-adaptive device for unpacking finished cigarette boxes. Background Art

[0002] In the modern tobacco industry, various inspection devices are added to the production process of cigarettes, cigarette packs, and cigarette cartons. However, with the improvement of production quality standards and consumer demands, post-packaging random inspections and post-packaging tobacco logistics sorting are also required. Post-packaging random inspections involve unsealing the sealed cigarette boxes, removing the cigarette cartons, and inspecting their appearance to determine if there are any problems with the packaging process. Logistics sorting involves unsealing the cigarette boxes, separating the cigarette cartons and cartons, inspecting the cigarette cartons, and then allocating the quantity according to demand, completing the supply sorting process.

[0003] At present, traditional post-packaging random inspections are limited to manual unpacking, and then taking out the cigarette cartons one by one for visual inspection to judge the packaging quality of the cigarette cartons. This traditional method has a series of problems such as time-consuming and labor-intensive, high labor costs, low efficiency, and high personnel subjectivity. In addition, mechanical unpacking devices have appeared in tobacco logistics sorting. This device is suitable for boxes of cigarettes with a fixed single size and cannot be adapted to multiple specifications. Under the multi-specification box sizes of cigarette cartons, it is impossible to use a single device to adapt to the unpacking and cigarette inspection work of multiple specifications of cigarette cartons on the market.

[0004] In response to the above problems, there is an urgent need for an integrated device that can adapt to the unpacking equipment of finished cigarette boxes. Summary of the Invention

[0020] A method for unpacking self-adaptive finished cigarette boxes is also provided, comprising the following steps:

[0021] Step 1: transporting the box of cigarettes to the entrance positioning unit (2) through the entrance transport unit (1);

[0022] Step 2: When the tail end of the cigarette box reaches the action surface of the check block (201) in the direction of movement, the check block (201) moves under the drive of the linear motion unit (202), and when the front end of the cigarette box contacts the cigarette box limit plate (203), the linear motion unit (202) stops pushing and returns to the original state; the cigarette box moving part group (3) is initially located in front of the movement direction of the entrance conveying part group (1), and the cigarette box is pushed to the cigarette box moving part group (3) by the linear motion unit (202) in the entrance positioning part group (2);

[0023] Step 3: After the positioned cigarette box enters the multifunctional cigarette box moving unit (3), the cigarette box height clamping unit (302) and the cigarette box width clamping unit (303) of the multifunctional cigarette box moving unit (3) are controlled by air cylinders or electric cylinders for clamping cigarette boxes of different sizes in the height direction and width direction, and transporting them along the linear motion unit (301);

[0024] Step 4: When the cigarette box moves to the cutting seam group (4) station, the cylinder is pushed to control the movement stroke of the parallelogram swing rod (401), so that the appropriate height frame (402) contacts and fits with the upper surface of the cigarette box in the height direction. When the appropriate height frame (402) fits the upper surface of the cigarette box, the cylinder is pushed to stop moving. It can adapt to different cigarette box height sizes. The knife body frame (403) is fixed on the parallelogram swing rod (401). The knife body frame (403) can slide along the front swing rod to achieve the position adjustment of the knife body frame (403). It can cut the sealing tape in accordance with different proportions. The knife fixed on the knife body frame (403) extends out to cut the tape.

[0025] Step 5: When the cigarette box moves to the trimming and seaming group (5) station, the cylinder is pushed to control the movement stroke of the parallelogram swing arm (501), and the height-appropriate frame (502) is used to contact and fit with the upper surface of the cigarette box in the height direction. When the height-appropriate frame (502) fits the upper surface of the cigarette box, the cylinder is pushed to stop moving, which can adapt to different cigarette box heights. The cutter body frame (503) is fixed on the parallelogram swing arm (501); the cigarette box width direction movement unit (504) can be expanded or contracted to adapt to the width of cigarette boxes of various specifications. The inserting plate (506) is used to insert into the middle seam after the tape is cut, and the retraction unit (505) is extended to retract and pull the carton flanging; the adhesive tape is completely torn off;

[0026] Step 6: When the cigarette box moves to the long side opening group (6) station, the height direction motion unit (601) starts to move from the top of the cigarette box. Since the tape fixation has been released in the previous process, the carton folding edge is under natural tension, and the two long sides of the carton are in an "eight" shape. Through the two movements of descending and rising, the lower side and the upper side of the long side are opened respectively; the guide unit (602) is realized by the cylinder extension and contraction. After the two long sides are opened after the height direction motion unit (601) is moved, the cylinder extends and presses the two long sides, playing a guiding role.

[0027] Step 7: When the cigarette box moves to the cigarette strip storage unit group (7) station, the multifunctional cigarette box moving unit group (3) is aligned with the cigarette strip storage unit group (7), and the cigarette box flip unit (304) in the multifunctional cigarette box moving unit group (3) rotates synchronously with the cigarette box flip unit (703) in the cigarette strip storage unit group (7). When the cigarette box rotates to the set angle, the cigarette strips slide and contact the cigarette strip pouring plate (702) by their own gravity. In addition, the cigarette strip pouring plate (702) is controlled by the cylinder and can move slowly. Since the cigarette box carton is clamped by the multifunctional cigarette box moving unit group (3), the carton will not move with the cigarette strips. When the cigarette strip pouring plate (702) moves to the end position, the cigarette strip pouring work is completed; the carton finally moves in the opposite direction under the rotation of the flip unit of the multifunctional cigarette box moving unit group (3). By releasing the clamping of the cigarette box width and height, the carton slides down by itself, and the cigarette box unpacking is completed, and the carton and cigarette strips are completely separated.

[0028] Furthermore, the method includes step 8: the separated cigarette strips are clamped by a robot picking unit (8) and poured out from the cigarette storage unit (7), and the cigarette strips are transferred to the cigarette conveying and inspection unit (9), and the appearance quality of the cigarette strips is inspected by machine vision.

[0029] The implementation of the present invention includes the following technical effects:

[0030] The adaptive finished cigarette box unpacking equipment of the present invention can independently complete the steps of conveying cigarette boxes of various specifications, cutting the sealing tape, and removing cigarette cartons. It can adapt to various cigarette box sizes, does not damage the cigarette cartons during the unpacking process, and has a simple structure. It has broad application prospects in solving existing technologies and industry problems. Furthermore, it can also perform visual inspection of the cigarette cartons' appearance, enabling simultaneous quality inspection during unpacking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The present invention will be described in detail below with reference to embodiments and drawings. It should be noted that the described embodiments are only intended to facilitate understanding of the present invention and do not have any limiting effect on the present invention.

[0042] See also Figure 1 As shown, the embodiment provides an adaptive finished cigarette box unpacking equipment, which includes an entrance conveying section group 1, an entrance positioning section group 2, a multifunctional cigarette box moving section group 3, a center seam cutting section group 4, a side seam cutting section group 5, a long side opening section group 6, a cigarette strip storage section group 7 and a frame 10. The entrance conveying section group 1 is used for conveying the entrance cigarette boxes; the entrance positioning section group 2 is used for moving and positioning the entrance cigarette boxes; the multifunctional cigarette box moving section group 3 is used for horizontally conveying the positioned cigarette boxes and separating the cigarette strips and cartons in the cigarette boxes; the center seam cutting section group 4 is used for cutting the tape bonded at the center seam of the long sides of the packaged cigarette boxes so that the two long sides can be free from the tape connection; the side seam cutting section group 5 is used for pulling and tearing the two long sides apart; the long side opening section group 6 is used for guiding the two long side sides of the cigarette boxes and guiding them during conveyance; the cigarette strip storage section group 7 is used for dumping and pouring out the cigarette strips after unpacking; and the frame 10 is used to support and fix the above sections. The frame 10 provides stable and reliable connections for the above functional groups, meeting the strength and stiffness requirements.

[0043] like Figure 2 As shown, the inlet conveyor assembly 1 is mounted on a frame 10 and comprises a plurality of conveyor rollers 101, a support frame 102, a round belt 103, and a power motor 104. The conveyor rollers 101 are mounted on the support frame 102 and connected by the round belt 103. The power motor 104 is connected to one of the conveyor rollers 101. Power is transmitted between the conveyor rollers 101 via the round belt 103, ultimately transporting the cigarette cases placed on the conveyor rollers 101 in a designated direction. Of course, this part of the conveying method is diverse, and similar conveying methods can also be used to transport cigarette cases.

[0044] like Figure 3As shown, the inlet positioning assembly 2 is mounted on the frame 10 and includes a check block 201, a linear motion unit 202, and a cigarette box limit plate 203. The check block 201 is mounted on the linear motion unit 202 and can reciprocate under the drive of the linear motion unit 202. The cigarette box limit plate 203 is used to locate the moving position of the cigarette box. When a cigarette box placed in the inlet conveying assembly 1 reaches the specified position, that is, the tail end of the cigarette box in the direction of movement reaches the action surface of the check block 201, the check block 201 moves under the drive of the linear motion unit 202. When the front end of the cigarette box in the direction of movement contacts the cigarette box limit plate 203, the linear motion unit 202 stops pushing and returns to its original state. The check block 201 is provided with a pressure sensor, and the stroke of the check block 201 is controlled according to the pressure sensor, thereby meeting the requirements of multiple specifications and sizes of cigarette box movement directions. When cigarettes of different lengths reach the cigarette limit plate (203), the rear end face of the cigarettes in the moving direction maintains contact with the check block (201). After the contact is pressed and compacted, the thrust of the linear motion unit (202) rises to a set value, and the linear motion unit (202) stops moving. In the initial state, the cigarette moving part group (3) is located in front of the moving direction of the entrance conveying part group (1). The cigarettes are pushed to the cigarette moving part group (3) by the linear motion unit (202) in the entrance positioning part group (2). After the cigarettes are clamped, the conveying movement can be carried out.

[0045] like Figure 4As shown, the multifunctional cigarette case moving unit 3 is mounted on the frame 10 and includes a linear motion unit 301 and a moving assembly. The linear motion unit 301 is mounted on the frame 10, and the moving assembly is mounted on the linear motion unit 301. The moving assembly can reciprocate along the linear motion unit 301 to achieve the transfer and horizontal transport of cigarette cases. The linear motion unit 301 is responsible for the horizontal transport of the entire cigarette case after the cigarette case is transferred from the entrance conveying unit 1 and the entrance positioning unit 2, and completes the work of the centering seam cutting unit 4, the side seam cutting unit 5, the long edge cutting unit 6, and the cigarette storage unit 7. The moving component includes a cigarette box height clamping unit 302, a cigarette box width clamping unit 303 and a cigarette box turning unit 304. The cigarette box height clamping unit 302 and the cigarette box width clamping unit 303 are arranged on the top of the bracket, and the cigarette box turning unit 304 is used to drive the cigarette box to tilt; the cigarette box height clamping unit 302 is used to clamp the cigarette box at the height during transportation. This process can correspond to the sizes of cigarette boxes with different heights. Parametric control can achieve the compression of cigarette boxes with different heights. This function can be achieved by using a cylinder or an electric cylinder; the cigarette box width clamping unit 303 is used to clamp the cigarette box at the width during transportation. This process can correspond to the sizes of cigarette boxes with different widths. Parametric control can achieve the compression of cigarette boxes with different widths. This function can be achieved by using a cylinder or an electric cylinder; the cigarette box turning unit 304 is controlled by a cylinder or an electric cylinder, one end of which is fixed on the bracket and the other end is fixed on the bottom plate of the clamping unit. The cigarette box turning unit 304 is used to pour out the cigarette strips after the cigarette box is opened and to tilt and separate the cigarette cartons.

[0046] like Figure 5 As shown, the center seam cutting group 4 is arranged on the frame 10, and the center seam cutting group 4 includes a parallelogram rocker arm 401, an appropriate height frame 402 and a knife body frame 403. The appropriate height frame 402 is arranged on the top of the parallelogram rocker arm 401, and a pushing cylinder is provided on the parallelogram rocker arm 401 for controlling the movement stroke of the parallelogram rocker arm 401. The appropriate height frame 402 is used to contact and fit with the upper surface of the box cigarette in the height direction. When the appropriate height frame 402 fits the upper surface of the box cigarette, the pushing cylinder stops moving. It can adapt to different box cigarette height sizes. The knife body frame 403 is fixed on the parallelogram rocker arm 401, and the knife body frame 403 can slide along the rocker arm to realize the position adjustment of the knife body frame 403. The fixed position of the knife body frame 403 can be set in equal proportion, and can correspond to different proportions of sealing tape for cutting. In addition, the tool is fixed on the knife body frame 403. The tool is connected to the air cylinder or electric cylinder and has the function of extending and retracting. The extending and retracting functions are realized by the air cylinder or electric cylinder.

[0047] like Figure 6As shown, the trimming seam group 5 is arranged on the frame 10, and the trimming seam group 5 includes a parallelogram rocker 501, an appropriate height frame 502 and a knife body frame 503. The parallelogram rocker 501 and the appropriate height frame 502 have the same cutting principle. The appropriate height frame 502 is set on the top of the parallelogram rocker 501. A pushing cylinder is set on the parallelogram rocker 501 to control the movement stroke of the parallelogram rocker 501. The appropriate height frame 502 is used to contact and fit with the upper surface of the box cigarette in the height direction. When the appropriate height frame 502 fits with the upper surface of the box cigarette, the pushing cylinder stops moving. It can adapt to different box cigarette height sizes. The knife body frame 503 is set on the parallelogram rocker 501. The blade frame 503 is equipped with a cigarette case width movement unit 504, an extension and retraction unit 505, and an inserting plate 506. The cigarette case width movement unit 504 and the inserting plate 506 are arranged on the extension and retraction unit 505. The inserting plate 506 is located at one end of the cigarette case width movement unit 504. The inserting plate 506 is used to insert into the center seam after the tape is cut. The extension and retraction unit 505 is retracted to pull the carton flange. The cigarette case width movement unit 504 can be expanded or retracted to accommodate various cigarette case widths. After the cigarette case center seam tape is cut by the center seam cutting unit 4, the inserting plate 506 is inserted into the side of the cigarette case center seam. The blade frame 503 then extends and retracts the retraction unit 505, which then pulls the carton flange and completely tears the adhesive tape.

[0048] like Figure 7 As shown, the long side opening group 6 is set on the frame 10, and the long side opening group 6 includes a height direction movement unit 601 and a guide unit 602. The height direction movement unit 601 and the guide unit 602 are arranged on a fixed column. The height direction movement unit 601 is provided with a long side guide plate 603. The height direction movement unit 601 can be lowered and raised along the fixed position. The long side guide plate 603 unfolds the two long sides of the carton 604. The guide unit 602 is extended and retracted by the cylinder to fully open the two long sides of the carton 604. The height direction movement unit 601 starts to move from the upper part of the cigarette box. Since the tape fixation has been released in the previous process, the folded edge of the carton 604 is under natural tension, and the two long sides of the carton 604 are in an "eight"-shaped open state. Through the two movements of descending and rising, the lower side and the upper side of the long side are opened respectively; the guide unit 602 realizes the opening of the two long sides after the height direction movement unit 601 is actuated through the extension and contraction of the cylinder. The cylinder extends out to support the two long sides, playing a guiding role.

[0049] like Figure 8As shown, the cigarette storage group 7 is arranged on the frame 10, and the cigarette storage group 7 includes a cigarette box width matching mechanism 701, a cigarette box pouring block 702 and a cigarette box turning unit 703. The cigarette box width matching mechanism 701 and the cigarette box pouring block 702 constitute a cigarette box placement table. The cigarette box width matching mechanism 701 is controlled by a cylinder and includes two side panels, one of which is fixed and the other is connected to the cylinder, which can meet the needs of cigarette boxes of different width specifications. The cigarette box turning unit 703 is used to drive the cigarette box placement table to tilt, and the cigarette box pouring block 702 can move up and down or left and right under the drive of the power mechanism. When the multifunctional cigarette box moving part group 3 moves to be flush with the cigarette storage part group 7, the cigarette box flip unit 304 in the multifunctional cigarette box moving part group 3 rotates synchronously with the cigarette box flip unit 703 in the cigarette storage part group 7. When the cigarette box rotates to the set angle, the cigarette box slides to contact the cigarette box pouring block 702 by its own gravity. In addition, the cigarette box pouring block 702 is controlled by the cylinder and can move slowly. This setting can realize the slow and orderly pouring of the built-in materials to avoid the chaos of the cigarette boxes. At this time, since the cigarette box 604 is clamped by the multifunctional cigarette box moving part group 3, the box 604 will not move with the cigarette box. When the cigarette box pouring block 702 moves to the end position, the pouring of the cigarette box is completed. Finally, the box 604 moves in the opposite direction under the rotation of the flip unit of the multifunctional cigarette box moving part group 3. By releasing the clamping of the width and height of the cigarette box, the box 604 slides down by itself. At this step, the unpacking of the cigarette box is completed, and the box 604 and the cigarette box are completely separated.

[0050] like Figure 1 As shown, the unpacking equipment also includes a robot picking unit 8, which is arranged on a frame 10. The robot picking unit 8 is used to pick up cigarettes from the cigarette storage unit 7 and transfer them to the next workstation after picking up the cigarettes. The robot picking unit 8 can use the robot to pick up cigarettes poured out of the cigarette storage unit 7 and transfer them to the cigarette conveying and detection unit 9. The robot picking unit 8 is a manipulator.

[0051] like Figure 9 As shown, the unpacking equipment also includes a cigarette conveyor inspection unit 9, which consists of a conveyor device 901, an industrial camera group 902, and a light source 903. The industrial camera group 902 and the light source 903 are arranged around the conveyor device 901. The industrial camera group 902 is used to take pictures of the appearance of the cigarettes, and the light source 903 is used for illumination. Through machine vision, the appearance quality of the cigarettes is inspected.

[0052] See also Figures 1 to 9 As shown, this embodiment also provides an adaptive finished product box cigarette unpacking method, comprising the following steps:

[0053] Step 1: The cigarettes in the box are transported to the entrance positioning unit group 2 through the entrance transport unit group 1;

[0054] Step 2: When the rear end of the cigarette box reaches the action surface of the check block 201, the check block 201 moves under the drive of the linear motion unit 202. When the front end of the cigarette box contacts the cigarette box limit plate 203, the linear motion unit 202 stops pushing and returns to its original state.

[0055] Step 3: The positioned cigarette boxes enter the multifunctional cigarette box moving unit 3. For cigarette boxes of different sizes, the cigarette box height clamping unit 302 and the cigarette box width clamping unit 303 of the multifunctional cigarette box moving unit 3 are controlled by air cylinders or electric cylinders to clamp cigarette boxes of different sizes in the height and width directions and transport them along the linear motion unit 301.

[0056] Step 4: When the cigarette box moves to the middle seam cutting group 4 station, the cylinder is pushed to control the movement of the parallelogram swing rod 401, so that the appropriate height frame 402 contacts and fits with the upper surface of the cigarette box in the height direction. When the appropriate height frame 402 fits the upper surface of the cigarette box, the cylinder is pushed to stop moving, which can adapt to different cigarette box heights. The knife body frame 403 is fixed on the parallelogram swing rod 401 and can slide along the front swing rod to adjust the position of the knife body frame 403. It can cut the sealing tapes of different proportions, and the knife fixed on the knife body frame 403 extends out to cut the tape.

[0057] Step 5: When the cigarette box moves to the trimming and seaming group 5 station, the cylinder is pushed to control the movement of the parallelogram swing arm 501. The height adjustment frame 502 is used to contact and fit with the upper surface of the cigarette box in the height direction. When the height adjustment frame 502 fits the upper surface of the cigarette box, the cylinder is pushed to stop moving. This can adapt to different cigarette box heights. The cutter frame 503 is fixed on the parallelogram swing arm 501; the cigarette box width direction movement unit 504 can be expanded or contracted to adapt to various cigarette box widths. The insert plate 506 is used to insert into the middle seam after the tape is cut, and the retraction unit 505 is extended and retracted to pull the carton flap; the adhesive tape is completely torn off;

[0058] Step 6: When the cigarette box reaches the long side opening group 6 station, the height direction motion unit 601 starts to move from the top of the cigarette box. Since the tape fixation has been released in the previous process, the carton folding edge is under natural tension, and the two long sides of the carton are in an "eight" shape. Through the two movements of descending and rising, the lower and upper sides of the long sides are opened respectively; the guide unit 602 is realized by the extension and contraction of the cylinder to achieve the opening of the two long sides after the height direction motion unit 601 is actuated. The cylinder extends to support the two long sides, playing a guiding role;

[0059] Step 7: When the cigarette box runs to the cigarette storage group 7 station, the multifunctional cigarette box moving group 3 is aligned with the cigarette storage group 7, and the cigarette box flipping unit 304 in the multifunctional cigarette box moving group 3 rotates synchronously with the cigarette box flipping unit 703 in the cigarette storage group 7. When it rotates to the set angle, the cigarettes slide and contact the cigarette box pouring block 702 by their own gravity. In addition, the cigarette box pouring block 702 is controlled by the cylinder and can move slowly. Since the cigarette box carton is clamped by the multifunctional cigarette box moving group 3, the carton will not move with the cigarettes. When the cigarette box pouring block 702 moves to the end position, the cigarette box pouring work is completed; the carton finally moves in the opposite direction under the rotation of the flip unit of the multifunctional cigarette box moving group 3, and by releasing the clamping of the cigarette box width and height, the carton slides down by itself, and the cigarette box unpacking is completed, and the carton and cigarettes are completely separated.

[0060] The method may also include step 8: the robot picking unit 8 picks up the separated cigarette rods poured out from the cigarette storage unit 7, transfers the cigarette rods to the cigarette conveying and inspection unit 9, and completes the inspection of the appearance quality of the cigarette rods through machine vision means.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
