The slicing of the whole box of cigarette blocks after unpacking is the first processing step in the silk-making processing. The existing whole box of cigarette blocks in domestic enterprises generally adopts forms such as slicing or inserting for processing. The main slicing form is slicing, with a market share of more than 90% for mainstream use. Generally, the slicing method of 3 knives into 4 slices or 2 knives into 3 slices is more commonly used. Enterprises choose the slicing form and the number of sliced pieces according to their own raw materials and the actual production capacity of the production line.

[0041] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0042] Aiming at the problem that the tobacco blocks are prone to stacking in layers after cutting, which will cause material blockage. The present invention provides a pin-type post-cut tobacco block stacking and removing device, including: a pin, a steering drive device, a fixed mounting rod, a rotating rod and a control unit; when the control unit detects that the pin inserts into the tobacco block and reaches the set depth threshold, it controls the rotating rod to rotate horizontally above the recycling bin and then rotate vertically, so that the tobacco blocks on the pin fall into the recycling bin. It solves the problem that the existing tobacco blocks are prone to stacking in layers after cutting, which is easy to cause material blockage and affects the material supply of subsequent processes, and can improve the automation level of equipment operation, improve the stable supply of materials and production efficiency.

[0043] As Figures 1 to 4As shown in the figure, a stacking and removing device for cut tobacco blocks with inserted pins includes: an inserted pin 5, a steering drive device, a fixed mounting rod 2, a rotating rod 4, and a control unit. The fixed mounting rod 2 is vertically arranged on the side of the conveyor frame 1. The rotating rod 4 is perpendicularly arranged with respect to the fixed mounting rod 2. The rotating rod 4 is in transmission connection with the steering drive device, and the rotating rod 4 is fixedly connected to the fixed mounting rod 2 through the steering drive device. The inserted pin 5 is perpendicularly arranged with respect to the rotating rod 4, and the inserted pin 4 is arranged at a set height with respect to the tabletop of the conveyor frame 1. The steering drive device is in signal connection with the control unit and is used to drive the rotating rod to horizontally rotate around the fixed mounting rod or vertically rotate around an axis parallel to the rotating rod. When the control unit detects that the inserted pin inserts into the tobacco block and reaches the set depth threshold, it controls the rotating rod to horizontally rotate above the recycling box and then vertically rotate, so that the tobacco block on the inserted pin drops into the recycling box 14.

[0044] Specifically, the set height of the inserted pin can be higher than the height of a single tobacco block and lower than or equal to 1.5 times the height of the tobacco block. When the tobacco blocks are stacked in layers, the tobacco blocks move along the tabletop of the conveyor frame, and the tobacco blocks higher than the height of a single tobacco block will be inserted by the inserted pin. When the control unit receives that the inserted pin reaches the set depth threshold, it controls the steering drive device to move, so that the rotating rod horizontally rotates above the recycling box and then vertically rotates, and then the tobacco block on the inserted pin falls into the recycling box. This device automatically picks up the upper-layer tobacco blocks in the stacked tobacco blocks through the inserted pin and transfers them to the recycling box, realizing the automatic and uniform sorting of the stacked tobacco blocks on the belt conveyor, ensuring the uniform distribution of the tobacco blocks on the belt conveyor, ensuring the accuracy of the material flow control in the subsequent process, improving the quality of the cut tobacco, and being able to improve the automation level of the equipment operation, improve the stable supply of materials and production efficiency.

[0045] As Figure 1 and Figure 4 As shown in the figure, the device further includes: a buffer device 4; the buffer device 4 is also arranged on the rotating rod, and the buffer device 4 is used to reduce the impact force formed when the tobacco block inserts into the inserted pin.

[0046] Further, the buffer device 4 includes: a buffer spring 4-2, a limit telescopic shaft 4-3, and a buffer plate 4-1. The buffer plate 4-1 is disposed parallel to the front of the rotating rod 3. A plurality of the buffer springs 4-2 and the limit telescopic shafts 4-3 are arranged between the buffer plate 4-1 and the rotating rod 3. Each buffer spring 4-2 is sleeved on a corresponding limit telescopic shaft 4-3. One end of the limit telescopic shaft 4-3 is fixedly connected to the rotating rod 3, and the other end of the limit telescopic shaft 4-3 is fixedly connected to the buffer plate 4-1. The buffer spring 4-2 is used to contract when the buffer plate 4-1 is impacted and reset when the buffer plate is not impacted. The limit telescopic shaft 4-3 is used to limit the contraction amount of the buffer spring.

[0047] In practical applications, when the tobacco block is inserted into the needle 5, an impact force is inevitably applied to the needle 5 and the rotating rod 3. The setting of the buffer spring 4-2 can weaken the impact force, greatly reducing the impact and preventing the rotating rod from being impacted and simultaneously applying an impact force to the rotary drive device, damaging the equipment. The limit telescopic shafts 4-3 corresponding to the buffer springs 4-2 one by one are sleeved inside the buffer springs 4-2. One end of the limit telescopic shaft 4-3 is fixedly connected to the buffer plate 4-1, and the other end of the limit telescopic shaft 4-3 is fixedly connected to the rotating rod. The telescopic limit shaft is used to limit the contraction path of the buffer spring 4-2, contract with the contraction of the buffer spring 4-2, and reset with the reset of the buffer spring 4-2. This buffer device can extend the service life of the rejection device and reduce the costs of maintenance and replacement of parts.

[0048] Furthermore, a plurality of the needles 5 are vertically arranged on the buffer plate 4-1, and the needles 5 are provided with reinforcing wings 13 to enhance the supporting effect of the needles 5 on the tobacco blocks.

[0049] The device further includes: an auxiliary push plate 12 and a cylinder 11; the cylinder 11 is fixedly connected to the rotating rod 3, the piston rod of the cylinder 11 is fixedly connected to the auxiliary push plate 12, and the control end of the cylinder 11 is in signal connection with the control unit. The auxiliary push plate 12 is disposed above the needles 5. When the cylinder 11 operates, the cylinder 11 drives the auxiliary push plate 12 to reciprocally push along the axial direction of the needles 5, so that the tobacco blocks on the needles fall off.

[0050] Specifically, when the rotating rod rotates vertically so that the tip of the needle 5 faces downward, the control unit controls the piston rod of the cylinder 11 to extend, pushing the auxiliary push plate 12 to quickly extend forward. The auxiliary push plate 12 pushes the tobacco block, applying an initial velocity to the tobacco block, so that the tobacco block slides off the needle 5 faster, preventing the situation where the tobacco block does not fall off the needle 5.

[0051] The device further includes: a distance sensor 6; the distance sensor 6 is arranged on the rotating rod 3 and is used for detecting whether the pin 5 picks up a tobacco block and obtaining the depth value of the pin inserted into the tobacco block. The distance sensor is in signal connection with the control unit, and the control unit controls the movement of the rotating rod when the depth value is greater than a set depth threshold value.

[0052] As Figure 1 and Figure 3 shown, the steering drive device includes: a first motor 7, a second motor 9, a first motor support 8 and a second motor support 10. The mounting surface of the first motor support 8 is arranged parallel to the fixed mounting rod 2, and the second motor support 10 is arranged at the top end of the fixed mounting rod 2. The first motor 7 is vertically arranged on the mounting surface of the first motor support 8, the transmission shaft of the first motor 7 is fixedly connected with the second motor support 10, the second motor 9 is vertically arranged on the mounting surface of the second motor support 10, and the transmission shaft of the second motor 9 is fixedly connected with the rotating rod 3. When the first motor 7 rotates, the first motor 7 drives the second motor support 10 to rotate vertically around the axis through the transmission shaft. When the second motor 9 rotates, the second motor 9 drives the rotating rod 3 to rotate horizontally around the fixed mounting rod 2 through the transmission shaft.

[0053] In practical applications, as Figures 1 to 4 shown, since the height of the pin is higher than that of a single tobacco block and lower than the height of the stacked tobacco blocks, when the tobacco blocks are not stacked, the pin normally passes through. When the tobacco blocks are stacked, when the stacked tobacco blocks pass through the pin, they are inserted onto the pin 5. The distance sensor 6 collects the distance to the obstacle and transmits the collected distance signal to the control unit. The control unit can adopt a microprocessor. As Figure 2 shown, the microprocessor is respectively in signal connection with the first motor, the second motor, the cylinder and the distance sensor. A distance lower limit value is set in the microprocessor. When the stacked tobacco blocks are inserted onto the pin, the distance between the distance sensor 6 and the obstacle collected is lower than the set distance lower limit value. The microprocessor determines that the pin has picked up the tobacco block and reaches the set depth threshold value. At this time, the microprocessor controls the second motor 9 to rotate 180 degrees, driving the pin 5 to the upper part of the recycling box 3. Then, the microprocessor controls the first motor 7 to rotate counterclockwise by 90 degrees, making the tip of the pin 5 face downwards. The tobacco block falls off the pin 5 under the action of gravity and drops into the recycling box 3. Since a distance upper limit value is set in the microprocessor, when the microprocessor determines that the distance between the distance sensor 6 and the obstacle is greater than the distance upper limit value, it indicates that the tobacco block has completely fallen off, and the microprocessor controls the first motor 7 and the second motor 9 to reset in sequence.

[0054] Further, as Figure 1 and Figure 3As shown, the first motor support 8 has an L-shaped structure. The horizontal portion of the first motor support 8 is fixedly connected to the fixed mounting rod 2, such that the vertical portion of the first motor support 8 is arranged parallel to the fixed mounting rod. The first motor 7 is fixedly mounted on the vertical portion of the first motor support 8, such that the transmission shaft of the first motor 7 is perpendicular to the fixed mounting rod 2.

[0055] Furthermore, as Figure 1 and Figure 3 shown, one end of the second motor support 10 is a horizontal portion, and the other end portion of the second motor support 10 is an arc-shaped portion. An arc-shaped groove is provided at the top end of the fixed mounting rod 2, and the arc-shaped portion of the second motor support 10 is arranged in the arc-shaped groove.

[0056] It can be seen that the present invention provides a pin-type post-cut tobacco block stacking and removing device, including: a pin, a steering drive device, a fixed mounting rod, a rotating rod, and a control unit; when the control unit detects that the pin inserts into a tobacco block and reaches a set depth threshold, it controls the steering drive device to horizontally rotate above the recycling bin and then vertically rotate, so that the tobacco block on the pin falls into the recycling bin. This solves the problem that the tobacco blocks are stacked in layers after cutting, which is likely to cause material blockage and affect the material supply of subsequent processes, and can improve the automation level of equipment operation, improve the stable material supply and production efficiency.

[0057] The structure, features, and function effects of the present invention have been described in detail based on the illustrated embodiments above. The above are only the preferred embodiments of the present invention, but the present invention is not limited to the scope defined by the drawings. Any changes made according to the concept of the present invention, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the specification and drawings, shall be within the protection scope of the present invention.
