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, manual packaging is mostly used in the prior art. However, during the manual loading process, cigarettes must be placed step by step at a certain angle to ensure the appearance quality of the cigarettes, so the efficiency is very low.

[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 automatically and flexibly loading cigarettes in a side-opening cigarette box. In the referenced patent, the follower mold box is inserted obliquely into the cigarette box and then quickly retracts. The cigarettes in the follower mold box are retained 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. When the follower mold box is inserted into the cigarette box, defects such as the cigarette box being bruised or deformed and the backing paper being deformed may occur. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a cigarette box-entering 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 technical solution proposed by the utility model is: a cigarette box-entering device for a side-opening cigarette box, comprising a frame, a cigarette pushing mechanism and a sheet inserting mechanism, wherein the cigarette pushing mechanism and the sheet inserting mechanism are arranged on the frame;

[0007] The cigarette pushing mechanism is used to push the cigarettes in the mold box which is arranged obliquely relative to the box body of the cigarette box into the box body of the cigarette box;

[0008] The inserting piece mechanism comprises an inserting piece corresponding to the side wall of the box body and an inserting piece driving mechanism for driving the inserting piece to move;

[0009] When the cigarette is put into the box, the insert has a first state in which it is located above the box body, and a second state in which it is in contact with the left side wall or the right side wall of the box body; when the insert is in the first state, the insert is located horizontally in the cigarette box and has a preset interval with the left side wall or the right side wall of the box body.

[0010] When the utility model is in use, the cigarette box with the box cover and cover paper in the open state moves to the designated position (the position where the cigarettes are put into the box), and the cigarettes in the mold box also move to the corresponding designated position. At this time, the cigarettes in the mold box present a certain angle with the box body of the cigarette box, and the process of putting cigarettes into the box begins. First, the inserting mechanism is activated to control the inserting mechanism to extend forward to the 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 the position. At this time, the inserting mechanism extends forward to the cigarette storage cavity in the box body of the cigarette box, and is located on the inside of the cigarette box, a certain distance from the left and right side walls of the box body. 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 activated to push the cigarettes inside the mold box out of the mold box and into the box body of the cigarette box, and then each component mechanism returns to the initial state in order.

[0011] 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.

[0019] 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.

[0020] The cigarette inserting device for a side-opening cigarette box of this embodiment is as follows: Figure 2 and Figure 4 As shown, it is used in conjunction with the cigarette box conveying device and the mold box conveying device to complete the cigarette packing. The cigarette box conveying device moves the cigarette box 100 with the box cover 102 and the cover paper 103 already in the open state to the designated position. At the same time, the cigarette 107 is located in the mold box 407 (it should be noted that the method and device for loading the cigarette 107 into the mold box 407 are both prior art) and is moved to the corresponding designated position through the mold box conveying device 300. At this time, the cigarette 107 in the mold box 407 presents a certain angle with the cigarette box 100, which is about 8.4° in this embodiment, and the subsequent cigarette packing process begins. Figure 2 As shown, the cigarette box conveying device and the mold box conveying device 300 both adopt turntable conveying. Of course, traditional conveying methods such as conveyor belts can also be used.

[0021] like Figure 3 As shown, the cigarette box-entering device 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 .

[0022] like Figure 2-Figure 4As 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 into the box body 101 of the cigarette box 100. The cigarette pushing mechanism includes a cigarette pushing plate 410 and a cigarette driving mechanism that drives the cigarette pushing plate 410 to move along the inner cavity of the mold box 407. Preferably, the cigarette driving mechanism is preferably a cigarette pushing plate driving cylinder. After the cigarette pushing plate 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] In order to ensure that all cigarettes 107 are in place after the cigarettes are put into the box, preferably, Figure 2 and Figure 4 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.

[0028] This embodiment can also be improved as follows: Figure 2 , Figure 3 and Figure 5As 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. Preferably, in this embodiment, as Figure 5 As shown, the mechanism for shifting the backing paper 104 includes a crank 422 (cam) driven by a motor 421 and a connecting rod 423 hinged to the crank 422, the connecting rod 423 is provided with a waist-shaped hole 425 and a paddle 424, the frame 1 is provided with a pin 426 inserted into the waist-shaped hole 425, the waist-shaped hole 425 and the paddle 424 are respectively located on both sides of the hinge between the crank 422 and the connecting rod 423, the crank 422 and the connecting rod 423 hinged to the crank 422 form a similar crank slider mechanism under the constraints of the waist-shaped hole 425 and the pin 426, the connecting rod 423 swings under the drive of the crank 422, and the paddle 424 at the end of the paddle rod performs an arc motion with the continuous action of the crank slider mechanism, the paddle 424 opens the backing paper 104 upward by a certain distance to ensure that when the cigarette 107 is put into the box, the cigarette 107 and the backing paper 104 do not interfere with each other.
