DETAILED DESCRIPTION

[0039] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0040] As Figures 1-11As shown, one embodiment of the utility model provides a kind of cigarette packing bagging device, including rack 1, conveying mechanism, bagging device 3 and push cigarette device 4, conveying mechanism is installed on rack 1;Bagging device 3 and push cigarette device 4 are set to the same side of conveying mechanism, bagging device 3 and push cigarette device 4 are arranged along the direction of conveying mechanism perpendicular to the conveying direction, and loading table is set between bagging device 3 and push cigarette device 4;Bagging device 3 is used to open packaging bag, it includes installation portal frame 7, first bidirectional drive component, second bidirectional drive component and four film pieces, first bidirectional drive component and second bidirectional drive component are arranged and installed on installation portal frame 7 along vertical direction, two film pieces are installed on first bidirectional drive component, and other two film pieces are installed on second bidirectional drive component;First bidirectional drive component is used to drive two film pieces to be close to each other or be far away from each other along the direction of conveying mechanism of conveying mechanism, and second bidirectional drive component is used to drive two film pieces to be close to each other or be far away from each other along the direction of conveying mechanism of conveying mechanism;Push cigarette device 4 is used to push the cigarette stack on loading table into the packaging bag opened by bagging device 3.

[0041] When using the present cigarette packing bagging device to bag the cigarette stack, worker stands at the bagging station 28 of the bagging device 3, and then controls the first bidirectional drive component to drive two film pieces to be far away from each other along the direction of conveying mechanism of conveying mechanism, and simultaneously controls the second bidirectional drive component to drive other two film pieces to be far away from each other along the direction of conveying mechanism of conveying mechanism, so that the bag opening of the packaging bag is opened to the maximum extent. Figure 1

[0042] Thus, it is not necessary to open the bag opening of the packaging bag by multiple workers, and it is not necessary to manually push the cigarette stack into the packaging bag by workers, and a single person can complete the bagging operation, the efficiency of bagging is greatly improved, and the labor burden of workers is reduced.

[0043] As can be seen, the present cigarette packing bagging device replaces the manual opening of the bag opening by bagging device 3, and replaces the manual pushing of the cigarette stack by push cigarette device 4, and the whole bagging process only needs to manually put the bag opening of the packaging bag between the four film pieces of the bagging device 3, so that a single person can complete the bagging operation.

[0044] ​It needs to be clear that generally fixed size of the cigarette stack needs to use the corresponding size of the packaging bag to bag, generally will not use the large size of the packaging bag to bag small size of the cigarette stack. In the embodiment, the height difference between the film supporting piece on the first bidirectional driving assembly and the film supporting piece on the second bidirectional driving assembly is slightly smaller than the height value of the used packaging bag after being completely opened. That is, when the worker puts the packaging bag on the four film supporting pieces, the height direction of the packaging bag is opened, and then only the first bidirectional driving assembly drives two film supporting pieces to move away from each other along the conveying direction of the conveying mechanism, and at the same time, the second bidirectional driving assembly drives the other two film supporting pieces to move away from each other along the conveying direction of the conveying mechanism, so as to completely open the packaging bag.

[0045] When the packaging bag corresponding to the size of the cigarette stack is used up, since the height difference between the film supporting piece on the first bidirectional driving assembly and the film supporting piece on the second bidirectional driving assembly cannot be adjusted, it is impossible to use a packaging bag of a larger size to bag. Therefore, in the embodiment, a jacking cylinder 10 is further added, the jacking cylinder 10 is provided at least one, the jacking cylinder 10 is vertically installed on the mounting gantry 7, the first bidirectional driving assembly is installed on the cylinder end of the jacking cylinder 10, and the jacking cylinder 10 is used to drive the first bidirectional driving assembly to rise and fall to change the height of the two film supporting pieces installed on the first bidirectional driving assembly.

[0046] In this way, when the packaging bag corresponding to the size of the cigarette stack is used up and a packaging bag of a larger size needs to be used to bag, the worker first puts the packaging bag between the four film supporting pieces of the bag opening device 3, then controls the jacking cylinder 10 to extend to a set length to drive the two film supporting pieces on the first bidirectional driving assembly to rise to a certain height, so as to increase the height difference between the film supporting piece on the first bidirectional driving assembly and the film supporting piece on the second bidirectional driving assembly, and finally controls the first bidirectional driving assembly to drive two film supporting pieces to move away from each other along the conveying direction of the conveying mechanism, and at the same time, controls the second bidirectional driving assembly to drive the other two film supporting pieces to move away from each other along the conveying direction of the conveying mechanism, so as to open the packaging bag. In this way, the adaptability and practicality of the bag opening device 3 are greatly improved.

[0047] In the embodiment, as shown in Figure 1 the top of the gantry 1 is provided with a bearing frame 101, the conveying mechanism is a roller conveying line 2, the roller conveying line 2 is installed on the top of the bearing frame 101, a fixed frame 103 is welded on the back of the gantry 1, the bag opening device 3 is installed on the top of the gantry 1, and the cigarette pushing device 4 is installed on the fixed frame 103. In addition, a plurality of supporting legs 102 are fixedly installed on the bottom of the gantry 1.

[0048] For the convenience of description, the two film supporting pieces on the first bidirectional driving assembly are named as the first film supporting piece 16 and the second film supporting piece 17 in sequence, and the two film supporting pieces on the second bidirectional driving assembly are named as the third film supporting piece 18 and the fourth film supporting piece 19 in sequence.

[0049] After the packaging bag is sleeved on the bag supporting device 3, it is necessary to ensure that the bottom of the packaging bag is as close as possible to the conveying surface of the roller conveying line 2, so as to facilitate the subsequent entry of the cigarette stack. As shown in Figure 3 The third supporting film piece 18 and the fourth supporting film piece 19 on the second bidirectional driving assembly are slightly higher than the conveying surface of the roller conveying line 2, and the height difference between the third supporting film piece 18, the fourth supporting film piece 19 and the conveying surface of the roller conveying line 2 is very small, for example, 2mm, so that after the packaging bag is sleeved on the four supporting film pieces, the lower surface of the packaging bag can be as close as possible to the conveying surface of the roller conveying line 2.

[0050] However, since the gap between the third supporting film piece 18, the fourth supporting film piece 19 and the conveying surface of the roller conveying line 2 is small, it is not very convenient for workers to perform the bag sleeving operation.

[0051] Therefore, the transverse driving assembly 6 is added, the transverse driving assembly 6 is installed on the machine frame 1, and the installation gantry 7 is vertically installed on the transverse driving assembly 6, and the transverse driving assembly 6 is used to drive the installation gantry 7 to approach or move away from the roller conveying line 2.

[0052] In this way, before sleeving the bag, the transverse driving assembly 6 drives the installation gantry 7 to move away from the roller conveying line 2, so that the third supporting film piece 18 and the fourth supporting film piece 19 move backward to avoid the roller conveying line 2, that is, the projection of the third supporting film piece 18 and the fourth supporting film piece 19 in the direction towards the roller conveying line 2 is staggered with the roller conveying line 2. This facilitates the workers to perform the bag sleeving operation, and when the bag sleeving is completed, the transverse driving assembly 6 drives the installation gantry 7 to approach the roller conveying line 2, so as to move the four supporting film pieces above the roller conveying line 2, and at this time, the bag opening of the packaging bag is close to the conveying surface of the roller conveying line 2.

[0053] Preferably, as shown in Figure 4 and Figure 10As shown, the horizontal movement driving assembly 6 comprises a bearing seat 601, four mounting supports 602, two light shafts 603, a push cylinder 605 and a sliding block 604. The bearing seat 601 is fixedly installed on the top of the rack 1. The four mounting supports 602 are fixedly installed on the top surface of the bearing seat 601, and the four mounting supports 602 are divided into two groups, each group comprising two mounting supports 602. The two light shafts 603 are fixedly installed between the two mounting supports 602 of the two groups of mounting supports 602, and the extension direction of the light shaft 603 is perpendicular to the conveying direction of the roller conveying line 2. The sliding block 604 is in sliding connection with the two light shafts 603, the bottom of the mounting gantry 7 is fixedly installed on the sliding block 604, the push cylinder 605 is fixedly installed on the bearing seat 601, and the cylinder end of the push cylinder 605 is fixedly connected with the sliding block 604. The push cylinder 605 is used to push the sliding block 604 to move along the width direction of the roller conveying line 2, so that the mounting gantry 7 is close to or away from the roller conveying line 2. Further, the push cylinder 605 is provided with a second electromagnetic valve 606, and the second electromagnetic valve 606 is used to control the on-off of the gas in the push cylinder 605.

[0054] In order to accurately control the movement range of the mounting gantry 7, as shown in Figure 10 A third photoelectric sensor 607 and a fourth photoelectric sensor 608 are fixedly installed on the top of the bearing seat 601, the third photoelectric sensor 607 and the fourth photoelectric sensor 608 are arranged along the extension direction of the push cylinder 605, and the fourth photoelectric sensor 608 is closer to the mounting gantry 7. A trigger block is installed on the right side surface of the sliding block 604. The push cylinder 605, the third photoelectric sensor 607 and the fourth photoelectric sensor 608 are respectively in communication connection with the programmable controller on the rack 1.

[0055] When the bag needs to be sleeved, the programmable controller controls the push cylinder 605 to shorten the set length to pull the sliding block 604 to drive the mounting gantry 7 to move a fixed distance backward, until the trigger block on the right side of the sliding block 604 moves to the third photoelectric sensor 607, so that the light emitted by the third photoelectric sensor 607 is blocked by the trigger block. It is indicated that the mounting gantry 7 has reached the first limit position. At this position, the four film supporting pieces of the bag supporting device 3 move to the rear of the roller conveying line 2 to facilitate the worker to sleeve the bag. After the bag is sleeved, the programmable controller controls the push cylinder 605 to extend the set length to push the sliding block 604 to drive the mounting gantry 7 to move a fixed distance forward, until the trigger block on the right side of the sliding block 604 moves to the fourth photoelectric sensor 608. The programmable controller receives the signal of the fourth photoelectric sensor 608, thereby controlling the push cylinder 605 to stop, so that the mounting gantry 7 reaches the second limit position. At this position, the four film supporting pieces of the bag supporting device 3 are located above the roller conveying line 2, that is, it reaches the state as shown in Figure 3

[0056] ​In the embodiment, the installation gantry 7 is a "mouth" type frame, and a passageway is formed in the interior of the installation gantry 7.

[0057] As an embodiment, a horizontal arranged loading platform is fixedly installed on the installation gantry 7, the loading platform is perpendicular to the roller conveying line 2, and the loading platform is in the shape of a long board, a first end of the loading platform is close to the back of the roller conveying line 2, and the other end of the loading platform is close to the vertical plate 401 of the cigarette pushing device 4, and the top surface of the loading platform is parallel to the conveying surface of the roller conveying line 2. In this way, the worker stands at the back of the machine frame 1 to carry the cigarette stack to the loading platform, and then uses the cigarette pushing device 4 to push the cigarette stack on the loading platform towards the roller conveying line 2, and the cigarette stack enters the roller conveying line 2 through the passageway of the installation gantry 7.

[0058] As another specific embodiment, as shown in Figure 2 the sleeve bag device for the cigarette packaging further comprises a chain plate conveying line 5, the chain plate conveying line 5 is arranged between the cigarette pushing device 4 and the installation gantry 7, and is parallel to the roller conveying line 2, and further, a horizontal arranged transition plate 15 is installed in the interior of the installation gantry 7, one end of the transition plate 15 is close to the chain plate conveying line 5, and the other end of the transition plate 15 is close to the roller conveying line 2, and the conveying surface of the roller conveying line 2, the top surface of the transition plate 15 and the conveying surface of the chain plate conveying line 5 are flush. In this way, the worker can place the cigarette stack on the chain plate conveying line 5, the chain plate conveying line 5 conveys the cigarette stack, when the cigarette stack moves to the front of the cigarette pushing device 4, the chain plate conveying line 5 stops, then the cigarette pushing device 4 pushes the cigarette stack on the chain plate conveying line 5, the cigarette stack on the chain plate conveying line 5 is pushed to the transition plate 15, and finally moves from the transition plate 15 to the roller conveying line 2. At this time, the conveying surface of the chain plate conveying line 5 and the transition plate 15 are equivalent to the above-mentioned loading platform, but at this time, it is not necessary to increase the loading station at the back of the machine frame 1 and the right side of the cigarette pushing device 4, and it is not necessary to configure the carrying personnel at the loading station, but the chain plate conveying line 5 directly conveys the cigarette stack to the front of the cigarette pushing device 4.

[0059] Optionally, a plurality of vertical arranged blocking plates 501 are arranged on the conveying surface of the chain plate conveying line 5 along the conveying direction of the chain plate conveying line 5, and the cigarette stack is placed between two adjacent blocking plates 501, so as to avoid that the two adjacent cigarette stacks are in contact or collide.

[0068] Thus, after the worker puts the bag opening of the packaging bag on the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19, the programmable controller selectively controls the lifting cylinder 10 according to the size of the packaging bag. If the packaging bag used is of the same size as the stack of cigarettes to be sleeved, the programmable controller controls the first cylinder 111, the second cylinder 121, the third cylinder 131 and the fourth cylinder 141 to simultaneously extend by a fixed length, so that the first film supporting piece 16 and the second film supporting piece 17 are away from each other, the third film supporting piece 18 and the fourth film supporting piece 19 are away from each other, and the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19 support the four corners of the packaging bag. If the packaging bag used is one or several sizes larger than the matching packaging bag, the programmable controller needs to first control the lifting cylinder 10 to extend by a fixed length, so that the first film supporting piece 16 and the second film supporting piece 17 rise by a fixed height, to support the packaging bag in the height direction of the packaging bag, and then control the first cylinder 111, the second cylinder 121, the third cylinder 131 and the fourth cylinder 141 to simultaneously extend by a fixed length, so that the first film supporting piece 16 and the second film supporting piece 17 are away from each other, the third film supporting piece 18 and the fourth film supporting piece 19 are away from each other, and the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19 support the four corners of the packaging bag.

[0069] As an optional embodiment, in order to constrain the transverse movement range of the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19, as shown, Figure 7 As shown, the fifth photoelectric sensor 20 and the sixth photoelectric sensor 21 are installed above the first long strip hole 801, and the fifth photoelectric sensor 20 and the sixth photoelectric sensor 21 are respectively located at the left end and the right end of the first long strip hole 801.

[0070] The seventh photoelectric sensor 22 is installed above the second long hole 802, the eighth photoelectric sensor 23 is installed below the second long hole 802, the seventh photoelectric sensor 22 is located at the right side of the second long hole 802, and the eighth photoelectric sensor 23 is located at the left side of the second long hole 802.

[0071] As shown in the drawings, the ninth photoelectric sensor 24 and the tenth photoelectric sensor 25 are arranged below the third long hole 901, the ninth photoelectric sensor 24 is close to the left end of the third long hole 901, and the tenth photoelectric sensor 25 is close to the middle of the third long hole 901.

[0073] The automatic cigarette pushing device 4 in the embodiment comprises a vertical plate 401, two shaft rods 404, a cigarette pushing cylinder 402 and a pushing plate 403. Figure 2 As shown in the drawings, the vertical plate 401 is vertically installed on the fixed frame 103, and the vertical plate 401 is parallel to the installation door frame 7. Figure 11 As shown in the drawings, the vertical plate 401 is vertically installed on the fixed frame 103, and the vertical plate 401 is parallel to the installation door frame 7.The first end of the shaft rod 404 passes through the hole on the vertical plate 401, and the pushing plate 403 is fixedly installed on the first end of the two shaft rods 404.

[0074] It should be noted that the pushing plate 403 is higher than the chain plate conveying line 5 and the transition plate 15, and the projection of the pushing plate 403 in the direction towards the installation door frame 7 falls into the channel of the installation door frame 7, so as to ensure that when the cigarette pushing cylinder 402 is elongated, the pushing plate 403 pushes the cigarette stack on the chain plate conveying line 5 to the transition plate 15 and then enters the roller conveying line 302 through the transition plate 15.

[0075] Optionally, in order to control the moving range of the pushing plate 403, the first electromagnetic valve 409 is connected with the first photoelectric sensor 22, the second electromagnetic valve 410 is connected with the second photoelectric sensor 23, the third electromagnetic valve 411 is connected with the third photoelectric sensor 24, the fourth electromagnetic valve 412 is connected with the fourth photoelectric sensor 25, the fifth electromagnetic valve 413 is connected with the fifth photoelectric sensor 26, and the sixth electromagnetic valve 414 is connected with the sixth photoelectric sensor 27. Figure 11As shown, the horizontal plate 405 is fixedly installed on the back of the vertical plate 401 and is perpendicular to the vertical plate 401. The first trigger piece 408 is installed at the tail end of the shaft 404, and the first photoelectric sensor 406 and the second photoelectric sensor 407 are sequentially installed on the horizontal plate 405 along the length direction of the horizontal plate 405, wherein the first photoelectric sensor 406 is away from the vertical plate 401, and the second photoelectric sensor 407 is close to the vertical plate 401. When the first trigger piece 408 moves to the first photoelectric sensor 406 or the second photoelectric sensor 407, the programmable controller receives the signal fed back by the first photoelectric sensor 406 or the second photoelectric sensor 407, and the programmable controller controls the tobacco pushing cylinder 402 to stop.

[0076] It should be noted that the industrial computer is also arranged on the rack 1, and all the electromagnetic valves and photoelectric sensors mentioned above are in communication connection with the programmable controller (PLC), and the programmable controller is in signal connection with the industrial computer. The industrial computer is connected with the PLC through a communication network (such as an Ethernet) to realize data exchange and transmission of control commands. The industrial computer can serve as an upper computer and is responsible for monitoring and managing the system, and the PLC serves as a lower computer and is responsible for specific control tasks.

[0077] In addition, it should be clear that the use of the cigarette packaging sleeve device to sleeve the packaging bag on the cigarette stack is only one of many application scenarios of the cigarette packaging sleeve device. The cigarette packaging sleeve device can also be applied to other material sleeve application scenarios, such as the sleeve of a packaging box.
