Description

Technical Field

[0001] The utility model relates to a cigarette box-entering device for a side-opening cigarette box, belonging to the technical field of cigarette packaging. Background Art

[0002] The side-opening cigarette box is a common cigarette box, which is briefly described as follows: Figure 1 As shown, it consists of a box body 101 and a box cover 102. The box body is provided with a cigarette storage cavity 105 for accommodating cigarettes. The four side walls of the box body 101 are marked as A, B, C and D respectively. The box cover 102 can rotate around one side (side A) of the box body 101 in the width direction, so that the box cover is opened from the side. A decorative cover paper 103 is provided between the box cover 102 and the box body 101. The cover paper 103 can rotate around the side A of the box body 101 like the box cover 102. A lining paper 104 is provided at one end of the box body close to the side D. The lining paper 104 is connected to the box body 101 by bonding. Specifically, the lining paper 104 is bonded to the side B and the side D of the box body 101, and the lining paper 104 close to the side A of the box body 101 is in a free state, so as to facilitate the packing and taking out of cigarettes.

[0003] Due to the limitations of the opening method and the form of cigarette loading of side-opening cigarette boxes, the existing technology mostly adopts manual packaging, where the person first opens the cigarette box cover, then lifts the decorative cover paper, then removes the outer packaging of several cigarettes pre-packed by other cigarette packaging equipment, and finally takes out the arranged cigarettes and gently puts them into the cigarette box. However, in the process of manual cigarette loading, the cigarettes must be put in step by step according to a certain angle to ensure the appearance quality of the cigarettes, so the efficiency is very low, and the repeated mechanical cigarette loading action is also easy to cause worker fatigue.

[0004] The applicant searched and found that the Chinese patent with publication number CN116477107A (hereinafter referred to as the "referenced patent") discloses a device and method for automatic flexible cigarette loading in a side-opening cigarette box. The referenced patent has a cigarette box cover opening mechanism and a liner opening mechanism for pre-processing the cigarette box, a follow-up tilted cigarette bundle conveying mechanism for flexible cigarette loading, and a flexible cigarette pushing and boxing mechanism for pushing and straightening cigarettes arranged on the mounting base in sequence along the transport direction of the intermittent conveyor belt. The follow-up mold box is inserted obliquely into the cigarette box and then quickly retracted. The cigarettes in the follow-up mold box remain in the opened cigarette box under the damping of the smoke outlet baffle. However, the applicant's experience shows that if Figure 1 As shown, a step is formed at the bonding point between the backing paper 104 and the B side of the box body 101. During the insertion of the follower mold box into the cigarette box, the mold box may rest against the step, causing defects such as damage to the cigarette box and deformation of the backing paper. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a cigarette box-putting device which can prevent a side-opening cigarette box from being damaged, deformed and the lining paper from being deformed.

[0006] In order to solve the above technical problems, the utility model proposes a cigarette box-entering device for a side-opening cigarette box, comprising a cigarette box conveying device, a cigarette box clamping device, a cigarette box opening device, a mold box conveying device and a cigarette box-entering device, wherein the cigarette box conveying device is provided with a plurality of workstations, and the cigarette box clamping device, the cigarette box opening device, the mold box conveying device and the cigarette box-entering device are arranged at different workstations of the cigarette box conveying device;

[0007] The cigarette box clamping device is used to clamp the cigarette box conveyed by the cigarette box conveying device, and the cigarette box opening device is used to open the box cover and cover paper of the cigarette box;

[0008] The cigarette-putting device comprises a cigarette-pushing mechanism and a piece-inserting mechanism, which are arranged on a frame; the mold box conveying device is used to convey the mold box to the cigarette-pushing mechanism, at which time, the mold box is tilted relative to the box body of the cigarette box; the cigarette-pushing mechanism is used to push the cigarettes in the mold box into the box body of the cigarette box; the piece-inserting mechanism comprises a piece corresponding to the side wall of the box body and a piece-inserting mechanism for driving the piece-inserting to move; when cigarettes are put into the box, the piece-inserting has a first state of being located above the box body, and a second state of being in contact with the left side wall or the right side wall of the box body; when the piece-inserting is in the first state, the piece-inserting is located in the cigarette box in the horizontal direction, and has a preset interval with the left side wall or the right side wall of the box body.

[0009] During the process of loading cigarettes into a box, the utility model has the cigarettes in the mold box presenting a certain angle with the box body of the cigarette box, firstly the inserting mechanism is actuated to control the inserting mechanism to extend forward to a certain position so that the front end of the inserting mechanism is close to the lining paper, and then the inserting mechanism is controlled to descend to a certain position, at which time the inserting mechanism extends forward to the cigarette storage cavity in the box body of the cigarette box and is located on the inner side of the cigarette box at a certain distance from the left and right side walls of the box body, and finally the inserting mechanism is controlled to open to both sides of the box body and fit with the left and right side walls of the box body; then the cigarette pushing mechanism is actuated to push the cigarettes in the mold box out of the mold box and into the box body of the cigarette box, and then each component mechanism returns to an initial state in sequence.

[0010] When the cigarette pushing mechanism of the utility model is in operation, the insert sheet can be used as a protective baffle to prevent cigarettes from falling out of the box body; in addition, since the lining paper and one side wall of the box body have a step at the bonding point, the cigarette may abut against the step when entering the box, damaging the lining paper or the cigarette. After the insert sheet is added, the cigarette moves along the insert sheet, which can prevent the cigarette from abutting against the step, thereby avoiding defects such as the cigarette box being hit or deformed and the lining paper being damaged or deformed, and also reducing the probability of cigarette damage.

[0025] First of all, it should be noted that Figure 1 As shown, in the present invention, the box body is used as a reference, the C side facing the box body is defined as the front, the D side is defined as the back, the B side is defined as the left, and the A side is defined as the right.

[0026] This embodiment relates to a cigarette box-entering device for a side-opening cigarette box, such as Figure 2 As shown, it includes a cigarette box conveying device 200, a cigarette box clamping device 2, a cigarette box opening device 500, a mold box conveying device 300 and a cigarette box feeding device 400. The cigarette box conveying device 200 is provided with a plurality of workstations, and the cigarette box clamping device 2, the cigarette box opening device 500, the mold box conveying device 300 and the cigarette box feeding device 400 are arranged at different workstations of the cigarette box conveying device 200.

[0027] The cigarette box clamping device 2 is used to clamp the cigarette box 100 conveyed by the cigarette box conveying device 200, and can be implemented by using existing technology. The present embodiment preferably adopts the following implementation methods, such as Figure 3-Figure 6As shown, the cigarette box clamping device 2 includes a pushing component and a cigarette clamping component, the cigarette clamping component includes a slide 601 arranged on the frame 1, a vertical slider 602 forming a moving pair with the slide 601, and a clip 603 fixed on the vertical slider 602, the clip 603 is located above the slide 601, and a horizontal smoke baffle 604 located below the clip 603 is provided on the side of the slide 601 away from the slider, and the clip 603 and the horizontal smoke baffle 604 form a cigarette clamping cavity 615.

[0028] The lifting assembly is used to make the vertical slider 602 reciprocate up and down along the slide 601. Figure 4 As shown, the push-up assembly in this embodiment includes a horizontal slider 605 moving along a slide 601, a driving mechanism 600 driving the horizontal slider 605, a cam 607 arranged on the horizontal slider 605, and a push rod 608 arranged on the vertical slider 602 and matching the cam 607. When the horizontal slider 605 moves along the slide 601, the vertical slider 602 slides up and down along the slide 601, so that the cigarette clamping cavity 615 in the cigarette clamping assembly has two states, one open and one closed. The slide 601 is provided with a second spring 609 for resetting the vertical slider 602. The driving mechanism 600 can adopt existing technologies such as cylinders, which will not be described in detail.

[0029] This embodiment converts the horizontal movement of the horizontal slider 605 into the vertical movement of the clamping piece 603 by setting the cooperation of the cam 607 and the push rod 608, thereby cleverly realizing the action of clamping the cigarette box 100, that is, the cigarette clamping cavity 615 in the cigarette clamping assembly is driven by the push-up assembly to open and close, thereby clamping the empty cigarette box 100 transmitted from the previous station by the conveyor belt, which is convenient for the subsequent cigarette packing work. This embodiment clamps the cigarette box 100 by adjusting the opening size of the cigarette clamping cavity, which not only meets the requirement of reducing space occupation, but also can control the automatic opening and closing of the cigarette clamping cavity through the slider mechanism in the cigarette clamping assembly to ensure that the empty cigarette box 100 is intact, and greatly avoids the occurrence of scratches and deformation on the surface of the cigarette box 100.

[0030] In order to facilitate the movement of the horizontal slider 605, a slide groove matching the horizontal slider 605 can be set on the slide 601. Preferably, the horizontal slider 605 in this embodiment is rod-shaped, and at least two pairs of guide rollers 611 are provided on the slide 601 in the horizontal direction. Each pair of guide rollers 611 are arranged upper and lower and clamp the horizontal slider 605, so that the structure can be simpler.

[0031] When the cigarette box 100 needs to enter the cigarette clamping cavity 615, the driving mechanism 600 drives the horizontal slider 605 to move forward along the guide roller 611, thereby driving the vertical slider 602 to rise along the guide rail direction of the slide seat 601, and at the same time, the second spring 609 connecting the vertical slider 602 and the slide seat 601 is pulled up, so that the cigarette clamping cavity has an opening size larger than the width of the cigarette box 100. When the cigarette box 100 completely enters the cigarette clamping cavity and needs to be clamped, the driving mechanism 600 retracts, and under the action of the pulling force of the second spring 609, the vertical slider 602 descends along the slide seat 601, so that the cigarette clamping cavity has a size smaller than the width of the cigarette box 100. However, since the second spring 609 is in an adaptive state, it can be ensured that the cigarette box 100 can be clamped without damaging the cigarette box 100.

[0032] like Figure 4 and Figure 5 As shown, preferably, a vertical smoke baffle 610 is provided between the clamping piece 603 and the horizontal smoke baffle 604, and the vertical smoke baffle 610 is located at the rear end of the cigarette clamping cavity. In this way, the cigarette box 100 to be clamped can be limited, which is convenient for the subsequent operation of inserting the cigarette 107 into the box. Preferably, the horizontal slider 605 is provided with a limiting groove 612 extending in the horizontal direction, and the slider 601 does not have a limiting pin 613 inserted into the limiting groove 612. Through the cooperation of the limiting groove 612 and the limiting pin 613, the moving distance of the horizontal slider 605 can be limited to prevent the stroke from being too large, thereby limiting the lifting distance of the clamping piece 603 and improving the efficiency of cigarette clamping.

[0033] The specific structure of the cigarette box conveying device 200 in this embodiment is not limited. It is preferred to use a turntable cigarette box conveying device 200. A plurality of cigarette box 100 fixing mechanisms are provided on the cigarette box conveying device 200, so that the cigarette boxes 100 can be transferred between various workstations of the cigarette box conveying device 200. The cigarette box clamping device 2, the box cover opening mechanism 501 of the cigarette box opening device 500, the cover paper opening mechanism 510 of the cigarette box opening device 500, and the cigarette inserting device 400 are sequentially arranged at different workstations of the cigarette box conveying device 200.

[0034] The cigarette box opening device 500 is used to open the box cover 102 and the cover paper 103 of the cigarette box 100. The present embodiment does not limit the opening method of the box cover 102 and the cover paper 103. However, preferably, the cigarette box opening device 500 in the present embodiment is as follows: Figure 7 and Figure 8 As shown, it includes a box cover opening mechanism 501 and a cover paper opening mechanism 510, which are arranged at different stations of the cigarette box conveying device 200. When in use, the box cover 102 is opened first, and then the cover paper 103 is opened.

[0035] The box cover opening mechanism 501 includes a first opening and closing rod 507 and a first driving mechanism 600 for driving the first opening and closing rod 507 to move, the end of the first opening and closing rod 507 is provided with a first suction nozzle 506 that cooperates with the box cover 102, and the frame 1 is provided with an elastic box cover baffle 502; the first suction nozzle 506 drives the box cover 102 to make it have a box blocking state located below the elastic box cover baffle 502. In the initial state, the box cover 102 is in contact with the box body 101, and the first suction nozzle 506 is driven by the first opening and closing rod 507 to absorb the box cover 102, and the box cover 102 then rotates around the root of the cigarette box 100 to open. When opening, the box cover 102 breaks the restraint of the elastic box cover baffle 502, and the elastic box cover baffle 502 can rotate around the opening and closing rod at a certain angle to adapt to the elastic force of the box cover 102. After opening in place, the first suction nozzle 506 is released to separate from the box cover 102, and the box cover 102 moves in the opposite direction to the elastic box cover baffle 502. Since the box cover 102 has a certain rigidity and has resilience after opening, the opened and rebounded box cover 102 contacts the elastic box cover baffle 502 to keep the box cover 102 in an open state. It can be seen that the opening process of the box cover 102 is the process of the elastic box cover baffle 502 swinging back and forth.

[0036] Preferably, a first arc-shaped transition guide 505 is provided at the end of the elastic box cover baffle 502 close to the first suction nozzle 506, and its arc-shaped structure ensures that the elastic box cover baffle 502 is not caught during the movement of the box cover 102.

[0037] In addition, the frame 1 may also be provided with a first spring for resetting the elastic cover baffle 502. Under the action of the first spring, the elastic cover baffle 502 can be prevented from oscillating back and forth when returning to its original position, thereby affecting the next opening of the cover 102. In order to limit the travel of the elastic cover baffle 502 and prevent it from moving too much, a limit block 503 is provided on the frame 1. A waist-shaped hole 425 may be provided on the elastic cover baffle 502. The limit block 503 is inserted into the waist-shaped hole 425, so that the swing amplitude of the elastic cover baffle 502 is controlled by the limit block 503.

[0038] After the box cover 102 is opened by the box cover opening mechanism 501, it continues to move to the next station, and the cover paper 103 is opened by the cover paper opening mechanism 510. Figure 7 and Figure 8As shown, the cover paper opening mechanism 510 includes a second opening and closing rod 513 and a second driving mechanism 600 for driving the second opening and closing rod 513 to move, the end of the second opening and closing rod 513 is provided with a second suction nozzle 512 that matches the cover paper 103, and the frame 1 is provided with a paper stopper 511 extending along the movement direction of the cigarette box conveying device 200; the second suction nozzle 512 drives the cover paper 103 to have a paper stopper state located below the paper stopper 511. Preferably, the end of the paper stopper 511 close to the second suction nozzle 512 is provided with a second arc-shaped transition guide.

[0039] The second driving mechanism 600 controls the movement of the opening and closing rod so that the second suction nozzle 512 touches the surface of the cover paper 103, and then the negative pressure generated connects the second suction nozzle 512 with the cover paper 103, and the cover paper 103 then rotates around the root of the cigarette box 100 to open. After the cover paper 103 is opened into place, the negative pressure releases the second suction nozzle 512 and separates it from the cover paper 103, and the cigarette box 100 continues to move to the paper baffle 511. Since the cover paper 103 is flexible, it can ensure that the box cover 102 and the cover paper 103 can pass normally after opening, thereby completing the opening of the cigarette box 100 and preparing for the subsequent entry of cigarettes 107 into the box.

[0040] The first driving mechanism 600 and the second driving mechanism 600 have various implementations, which are prior art and are not limited to this. In this embodiment, the first driving mechanism 600 and the second driving mechanism 600 both use rotary cylinders.

[0041] In this embodiment, an elastic box cover baffle 502 and a paper baffle 511 are provided. The box cover 102 is first kept in an open state by the elastic box cover baffle 502, and then the flexibility of the cover paper 103 is used to ensure that the paper baffle 511 can keep the box cover 102 and the cover paper 103 in an open state. The arrangement is clever and can smoothly open the cigarette box 100 and the cover paper 103. Moreover, the paper baffle 511 extends along the movement direction of the cigarette box conveying device 200, which can ensure that the cigarette box 100 will not be stuck during the subsequent movement process, thereby avoiding damage to the cigarette box 100 or the cover paper 103 when the cigarettes 107 are put into the box.

[0042] The cigarette box inserting device 400 is as follows Fig. 9 As shown, the cigarette box conveying device 200 and the mold box conveying device 300 are used together to complete the packing of cigarettes 107. The cigarette box conveying device 200 moves the cigarette box 100 with the box cover 102 and the cover paper 103 in the open state to the designated position. At the same time, the cigarettes 107 are located in the mold box 407 and are moved to the corresponding designated position through the mold box conveying device 300. At this time, the cigarettes 107 in the mold box 407 present a certain angle with the cigarette box 100, which is about 8.4° in this embodiment, and the subsequent packing process of the cigarettes 107 begins. Fig. 9As shown, the cigarette box conveying device 200 and the mold box conveying device 300 both adopt turntable conveying, and can also adopt traditional conveying methods such as conveyor belts.

[0043] like Fig.10 As shown, the cigarette box-entering device 400 of this embodiment includes a frame 1 , a cigarette pushing mechanism and a sheet inserting mechanism 401 , and the cigarette pushing mechanism and the sheet inserting mechanism 401 are arranged on the frame 1 .

[0044] like Figure 9-12 As shown, the cigarette pushing mechanism is used to push the cigarettes 107 in the mold box 407 which is tilted relative to the box body 101 of the cigarette box 100 into the box body 101 of the cigarette box 100. The cigarette pushing mechanism includes a cigarette pushing plate 410 and a cigarette 107 driving mechanism 600 which drives the cigarette pushing plate 410 to move along the inner cavity of the mold box 407. Preferably, the cigarette 107 driving mechanism 600 preferably has a cigarette pushing plate 410 driving cylinder. After the cigarette pushing plate 410 driving cylinder drives the cigarette pushing plate 410 to push the cigarette 107 into the box body 101 of the cigarette box 100, it returns to its position and waits for the next action.

[0045] The insert mechanism 401 includes an insert corresponding to the side wall of the box body 101 and an insert driving mechanism for driving the insert to move. When the cigarette is put into the box, the insert has a first state of being located above the box body 101, and a second state of being in contact with the left or right wall of the box body 101; when the insert is in the first state, the insert is located in the cigarette box 100 in the horizontal direction, and has a preset interval with the left or right wall of the box body 101, that is, it is located on the inner side of the box body 101. In order to facilitate the entry of the cigarette 107 into the box, preferably, a guide plate (not shown in the figure) is provided at one end of the insert close to the mold box 407. The first state can be the initial state of the insert, or it can be an intermediate state during the movement of the insert.

[0046] In this embodiment, the insert has two functions: 1) when the cigarette pushing mechanism is in operation, the insert acts as a protective baffle to prevent the cigarette 107 from falling out of the box body 101. Therefore, preferably, when the insert is in the second state, the top surface of the side wall of the box body 101 is higher than the bottom surface of the insert, but not higher than the top surface of the insert, that is, in the vertical direction, the top surface of the side wall of the box body 101 is located between the bottom surface of the insert and the top surface of the insert; 2) when the insert is in the second state, the top surface of the side wall of the box body 101 is higher than the bottom surface of the insert and the top surface of the insert; Figure 1 As shown, the lining paper 104 and the side wall B of the box body 101 have a step 106, and the width of the step 106 is the thickness of the lining paper 104. When the cigarette is put into the box, the cigarette 107 may rest on the step 106, thereby causing damage to the lining paper 104 or the cigarette 107. After adding the insert, the cigarette 107 moves along the insert, which can prevent the above phenomenon from happening.

[0047] In this embodiment, there are two inserting pieces, including a left inserting piece 403 and a right inserting piece 402. When the inserting piece is in the second state, the two inserting pieces are respectively attached to the left and right walls of the box body 101. The inserting piece driving mechanism can adopt various technical means such as a manipulator. In this embodiment, the left inserting piece 403 is driven to move left and right by the left inserting piece driving cylinder, the right inserting piece 402 is driven to move left and right by the right inserting piece driving cylinder, the left and right inserting pieces 403 and 402 are driven to move up and down by the vertical driving cylinder 409, and the left and right inserting pieces 403 and 402 are driven to move forward and backward by the front and rear driving cylinders 404. Of course, the insert can also be a single piece. When the insert is in the second state, the side wall of the box body 101 to which the insert is attached is the side wall with the lining paper 104 adhered, that is, the right insert 402 is omitted, and only the left insert 403 is arranged on the side close to the side wall of the box body 101B. In this way, it can be avoided that the cigarette 107 may be against the step 106 when the cigarette is put into the box.

[0048] The process of inserting cigarettes into the box in this embodiment is as follows: in the initial state, the left and right inserting plates 403 and 402 are in the first state, and the inserting mechanism 401 is first actuated, and the front and rear driving cylinders 404 are firstly used to control the inserting plates to extend forward to a certain position, at which time the front end of the inserting plates is close to the backing paper 104, and then the vertical driving cylinder 409 is actuated to control the inserting plates to descend to a certain position, so that the inserting plates are located inside the box body 101 of the cigarette box 100, and then the left and right inserting plate driving cylinders control the left and right inserting plates 403 and 402 to move forward and backward, and the inserting plates 403 and 402 are moved forward and backward, respectively. , 402 move toward the A and B side walls of the box body 101, so that the left and right insert pieces 403, 402 move toward each other and open, so that the left and right insert pieces 403, 402 are in the second state; then the cigarette pushing mechanism is activated to control the cigarette pushing plate 410 to move forward to push the cigarette 107 inside the mold box 407 out of the mold box 407 and into the cigarette box 100, thus completing the action process of the cigarette 107 entering the empty cigarette box 100, and then each mechanism returns to the initial state in sequence.

[0049] In order to ensure that all cigarettes 107 are in place after the cigarettes are put into the box, preferably, Figure 9-12 As shown, a pressing plate mechanism is provided on the frame 1, and the pressing plate mechanism includes a pressing plate 408 corresponding to the position and size of the box body 101 and a pressing plate driving mechanism for driving the pressing plate 408 to move up and down. When the cigarette pushing mechanism is actuated, the cigarette pushing plate 410 is controlled to move forward to push the cigarette 107 inside the mold box 407 out of the mold box 407 and into the cigarette box 100, and then the pressing plate driving mechanism drives the pressing plate 408 to press down to ensure that the cigarette 107 completely enters the box body 101.

[0050] This embodiment can also be improved as follows: Figure 9-12As shown, the backing paper mechanism on the frame 1 drives the backing paper 104 to open upwards by a certain distance when the cigarette 107 is put into the box, so as to ensure that the cigarette 107 and the backing paper 104 do not interfere with each other and prevent the backing paper 104 from affecting the cigarette 107 from entering the box. The backing paper mechanism can use a negative pressure backing paper suction cup driven by a lever. When the cigarette pushing mechanism is activated, the lever drives the backing paper suction cup to suck the backing paper 104 and move it upwards, so that the backing paper 104 is opened.

[0051] The cigarette loading method of the cigarette box loading device described in this embodiment includes the following steps:

[0052] Step 1: Clamp the cigarette box: the cigarette box conveying device conveys the cigarette box to the working position of the cigarette box clamping device, and the cigarette box clamping device clamps the cigarette box. Preferably, the cigarette box clamping device adopts Figure 3-Figure 6 The device shown in the figure, after the clamp moves upward, the cigarette box enters under the clamp, and then the clamp is recovered to clamp the cigarette box.

[0053] Step 2: Open the cigarette box: the cigarette box conveying device conveys the cigarette box to the station of the box cover opening mechanism, and the cigarette box opening device opens the box cover and the cover paper in sequence. Figure 7 and Figure 8 As shown, the cigarette box opening device includes a box cover opening mechanism and a cover paper opening mechanism. The first suction nozzle of the box cover opening mechanism sucks the box cover and flips it to the bottom of the elastic box cover baffle. After the first suction nozzle is released from adsorption, the box cover baffle supports the box cover to keep it in an open state; the cover paper opening mechanism drives the second suction nozzle to suck the cover paper through the second opening and closing rod, and flips it to the bottom of the paper baffle, and then the second suction nozzle is released from adsorption.

[0054] Step 3: Loading cigarettes into boxes: The mold box conveying device conveys the mold box filled with cigarettes to the cigarette pushing mechanism. At this time, the mold box is tilted towards the cigarette box to be loaded; the inserting mechanism drives the inserting blade to insert forward and then expand to both sides, so that the inserting blade fits the side wall of the box body, and then the cigarette pushing mechanism pushes the cigarettes in the mold box into the box body of the cigarette box. After the cigarettes are put into the box, they are conveyed to the next station by the cigarette box conveying device for other packaging work.

[0055] The cigarette loading method can also be improved as follows: 1) After the step 2 is completed, the backing paper is pushed away by the backing paper pushing mechanism until the step 4 is completed, the backing paper pushing mechanism is reset, and the backing paper returns to its original position. 2) After the step 3 is completed, the pressing plate of the pressing plate mechanism moves downward to level the cigarettes in the cigarette box.
