Description

TECHNICAL FIELD

[0001] The present application relates to the tobacco packaging technical field, and particularly relates to a cutting device, a feeding system and a cutting method. BACKGROUND

[0002] The trademark paper is used for the packaging of cigarettes. In general, in order to facilitate transportation and use, several hundred trademark papers are stacked together to form a paper stack, and are wrapped around by a bundling belt to form a packaging piece, which is placed on a pallet. The bundling belt can be kraft paper.

[0003] In the prior art, the trademark paper wrapped by the kraft paper is very convenient during transportation, but needs to be unpacked during trademark paper feeding. At present, the removal of the bundling belt is usually completed by a cutting device. The cutting device usually adopts an extrusion or suction cup adsorption mode to generate a gap between the bundling belt and the paper stack for a cutting blade to cut. However, due to different tightness of the bundling belt in bundling the paper stack, if the bundling belt is too tight, the gap generated by the extrusion mode is small, which affects the success rate of cutting, and the suction cup adsorption mode may cause the suction cup to break the vacuum and fail to pull out the gap; if the bundling belt is too loose, the bundling belt has an indefinite shape when the extrusion mode and the suction cup adsorption mode generate a gap between the bundling belt and the paper stack, which may cause the cutting blade to fail to completely cut the bundling belt, and the trademark paper is easily damaged during cutting. SUMMARY

[0065] Reference Figures 1 to 3 As shown, this embodiment provides a feeding system, which includes a cutting device 100, a feeding platform 200, a discharging platform 300, a feeding device 400, and a discharging device 500.

[0066] The cutting device 100 is used to unpack the package 10, which includes a stack of paper 11 and strapping 12 for binding the stack of paper 11. The stack of paper 11 can be understood as multiple sheets of paper stacked together, such as label paper.

[0067] The unloading platform 300 is located on the first side of the cutting equipment 100 along the first horizontal direction, the loading platform 200 is located on the second side of the cutting equipment 100 along the first horizontal direction, the loading device 400 is located on the periphery of the loading platform 200, the loading device 400 is used to transport the package 10 to the loading platform 200, and the unloading device 500 is located above the unloading platform 300, the unloading device 500 is used to clamp and transfer the paper stack 11.

[0068] Specifically, the cutting device 100 includes a cutting table 110, a friction baffle 120, a pushing device 130, a pressing device 140, a baffle driving device 150, and a cutting device 160. The cutting table 110 is used to place the package 10; the friction baffle 120 is disposed on a first side of the cutting table 110 along a first horizontal direction; the pushing device 130 is disposed on a second side of the cutting table 110 along the first horizontal direction, and is used to push the package 10 along the first horizontal direction until the strapping 12 is in contact with the friction baffle 120; the pressing device 140 is disposed above the cutting table 110, and is used to press the paper stack 11 on the cutting table 110 so that the top of the paper stack 11 forms a cutting gap with the strapping 12; the baffle driving device 150... The driving device 150 is connected to the friction baffle 120. The baffle driving device 150 drives the friction baffle 120 to reciprocate and rub the strapping 12 in the vertical direction, so that the side of the strapping 12 facing the friction baffle 120 moves upward relative to the paper stack 11. The cutting device 160 includes a cutting blade 161 disposed above the cutting table 110 and a cutting drive member 162 connected to the cutting blade 161. The cutting drive member 162 drives the cutting blade 161 to cut the area of ​​the strapping 12 located in the cutting gap and facing the friction baffle 120 in the second horizontal direction. Figure 1 and Figure 2 In the diagram, direction a is the first horizontal direction, direction b is the second horizontal direction, and direction c is the vertical direction.

[0069] It is understood that the pushing device 130 can push the package 10 from the loading table 200 to the cutting table 110, and can push the paper stack 11 from the cutting table 110 to the unloading table 300. In this embodiment, the top of the friction baffle 120 can be bent towards the unloading table 300 to form a transition, reduce the gap between the unloading table 300 and the friction baffle 120, and allow the paper stack 11 to be smoothly transferred from the cutting table 110 to the unloading table 300.

[0070] In this embodiment, the feeding system, through the setting of the cutting device 160, effectively ensures that the strapping 12 is completely cut and that the trademark paper is not easily damaged. Exemplarily, firstly, the pushing device 130 is controlled to push the package 10 along the first horizontal direction until the strapping 12 is in contact with the friction baffle 120, thereby positioning the package 10; secondly, the pressing device 140 presses the paper stack 11 to keep it fixed; then, the baffle driving device 150 drives the friction baffle 120 to reciprocate and rub the strapping 12 in the vertical direction, causing the strapping 12 to move upwards toward the side facing the friction baffle 120, thereby increasing the height toward the side facing the friction baffle 120, increasing the cutting gap, and keeping the side of the strapping 12 facing the friction baffle 120 upright or slightly curved, suitable for cutting by the cutting blade 161, ensuring that the strapping 12 is completely cut and that the trademark paper is not easily damaged. In one feasible implementation, the friction baffle 120 is driven by the baffle drive device 150 to move downward in the vertical direction and then upward once to ensure that the strapping 12 is suitable for cutting by the cutting blade 161.

[0071] It is worth mentioning that when the friction baffle 120 moves downward, the area of ​​the strapping strap 12 at the top and on the side facing the pushing device 130 gradually comes into contact with the paper stack 11, and the bottom area of ​​the strapping strap 12 always comes into contact with the paper stack 11, resulting in greater friction. The friction baffle 120 causes the strapping strap 12 to move upward relative to the paper stack 11 by a small amount or almost no movement. When the friction baffle 120 moves upward, only the bottom area of ​​the strapping strap 12 comes into contact with the paper stack 11, resulting in less friction. The friction baffle 120 causes the strapping strap 12 to move upward relative to the paper stack 11 by a larger amount. That is, the baffle driving device 150 drives the friction baffle 120 to rub the strapping strap 12 back and forth in the vertical direction, so that the total displacement of the strapping strap 12 on the side facing the friction baffle 120 relative to the paper stack 11 is upward.

[0072] It is worth mentioning that when the side of the strapping 12 facing the friction baffle 120 moves upward relative to the paper stack 11, the side of the paper stack 11 facing the friction baffle 120 limits the side of the strapping 12 facing the friction baffle 120. Even if the side of the strapping 12 facing the friction baffle 120 bends, the amount of bending is small and will not affect the cutting of the cutting blade 161.

[0073] In this embodiment, the strapping 12 has a folded angle 13 because it binds the paper stack 11. In a feasible implementation, when the baffle driving device 150 drives the friction baffle 120 to reciprocate and rub the strapping 12 in the vertical direction, the upper folded angle 13 of the strapping 12 on the side facing away from the friction baffle 120 moves to the top corner of the corresponding side of the paper stack 11 or slightly protrudes from the top corner of the corresponding side of the paper stack 11. The top of the strapping 12 is tilted, and the deformation of the strapping 12 is restricted by the folded angle 13, which can further reduce the amount of bending of the strapping 12 toward the friction baffle 120.

[0074] In one feasible implementation, when the friction baffle 120 drives the strapping 12 to move upward relative to the paper stack 11 towards the side of the friction baffle 120, the top of the friction baffle 120 is set lower than the top of the paper stack 11. This effectively prevents the friction baffle 120 from squeezing the trademark paper located at the top of the paper stack 11 through the strapping 12, that is, prevents the trademark paper at the top from curling up and interfering with the position of the cutting blade 161, thereby preventing the cutting blade 161 from damaging the trademark paper when cutting the strapping 12. For example, when the pushing device 130 pushes the package 10 against the friction baffle 120, the friction baffle 120 protrudes from the top of the paper stack 11 to adjust the stacking state of the paper stack 11, so that the paper stack 11 is stacked in the vertical direction.

[0075] Exemplarily, the baffle driving device 150 includes, but is not limited to, an electric cylinder or a pneumatic cylinder, such as a motor lead screw slide mechanism. Exemplarily, the baffle driving device 150 also includes a baffle position sensor (not shown), such as a linear displacement sensor or a slotted photoelectric switch, to detect the vertical position of the friction baffle 120 in real time.

[0076] Exemplarily, the cutting drive 162 includes, but is not limited to, an electric cylinder or a pneumatic cylinder, such as a linear slide cylinder. Exemplarily, the cutting drive 162 is provided with a blade position sensor (not shown), such as a magnetic switch or a slotted photoelectric switch, to detect the horizontal position of the cutting blade 161 in real time.

[0077] For example, the cutting blade 161 can be tilted. Specifically, the cutting blade 161 is located on the first side of the cutting table 110 along the first horizontal direction. The cutting blade 161 is tilted downward from the first side of the cutting table 110 to the second side along the first horizontal direction to avoid positional interference between the cutting device 160 and the package 10.

[0078] In this embodiment, reference is made to Figure 1 As shown, the pressing device 140 includes pressing blocks 141 and pressing drive members 142. At least one pressing block 141 is provided; the pressing drive members 142 are connected to all pressing blocks 141 and are used to drive the pressing blocks 141 to press the paper stack 11 on the cutting table 110.

[0079] For example, two pressure blocks 141 are provided, located on both sides of the strapping 12, to more stably fix the paper stack 11 and prevent the paper stack 11 from curling up with the strapping 12, thereby preventing the cutting blade 161 from damaging the label paper when cutting the strapping 12. In addition, it effectively prevents the paper stack 11 from shifting when the friction baffle 120 moves back and forth in the vertical direction, thus affecting the upward movement of the strapping 12 toward the side of the friction baffle 120.

[0080] For example, a pressure block 141 is provided and is located on the side of the paper stack 11 where the area of ​​the exposed strapping 12 is larger, which effectively reduces the friction between the strapping 12 and the cutting table 110 and the paper stack 11, and makes it easier for the friction baffle 120 to move upward along the side that drives the strapping 12 toward the friction baffle 120.

[0081] Of course, the number of pressing blocks 141 can be other than that specified in this application.

[0082] Exemplarily, the pressing drive 142 includes, but is not limited to, an electric cylinder or a pneumatic cylinder. Exemplarily, the pressing drive 142 is provided with a block position sensor (not shown), such as a magnetic switch, to detect the vertical position of the pressing block 141 in real time.

[0083] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 4As shown, the cutting equipment 100 also includes a lifting drive device 170, a limiting component 180, and an adsorption device 190. The lifting drive device 170 is connected to the cutting table 110 and drives the cutting table 110 to reciprocate vertically between the cutting station and the unloading station, where the binding strap 12 is cut at the cutting station. The limiting component 180 is located on the periphery of the cutting table 110 and extends vertically from the unloading station to the cutting station, limiting the paper stack 11 at the unloading station. The adsorption device 190 is located on a first side of the cutting table 110 along a first horizontal direction, adsorbing the binding strap 12 at the unloading station and causing it to detach from the paper stack 11. In this embodiment, the cutting station is located above the unloading station. The cutting table 110 of the cutting station is coplanar with the loading table 200 and the unloading table 300, or the cutting table 110 is lower than the loading table 200 and higher than the unloading table 300, to facilitate the transfer of the package 10. In this embodiment, after the strapping 12 is cut at the cutting station, firstly, the lifting drive device 170 drives the cutting table 110 to move the package 10 vertically from the cutting station to the unloading station. During the downward movement, the limiting component 180 limits the movement to ensure that the stack of paper stack 11 remains vertical. Then, the adsorption device 190 adsorbs the strapping 12 and pulls the strapping 12 away from the paper stack 11, so that the strapping 12 is completely separated from the paper stack 11. The structure is simple and will not cause the paper stack 11 to scatter.

[0084] Exemplarily, the lifting drive device 170 includes, but is not limited to, an electric cylinder or a pneumatic cylinder, such as a motor lead screw slide mechanism. Exemplarily, the lifting drive device 170 also includes a lifting position sensor (not shown), such as a linear displacement sensor or a slotted photoelectric switch, to detect the vertical position of the cutting table 110 in real time.

[0085] Specifically, the driving end of the lifting drive device 170 is connected to the cutting table 110, and a first guide mechanism (not shown), such as a slide rail slider mechanism, can be provided between the fixed end of the lifting drive device 170 and the cutting table 110 to ensure that the cutting table 110 moves stably in the vertical direction. Further, the fixed end of the baffle drive device 150 can be connected to the driving end of the lifting drive device 170, and a second guide mechanism (not shown), such as a slide rail slider mechanism, can be provided between the fixed end of the baffle drive device 150 and the friction baffle 120 to ensure that the friction baffle 120 moves stably in the vertical direction. In this embodiment, the lifting drive device 170 can drive the cutting table 110, the baffle drive device 150, and the friction baffle 120 to move in the vertical direction. It is understood that while the lifting drive device 170 drives the cutting table 110 to move in the vertical direction, the position of the friction baffle 120 relative to the cutting table 110 remains unchanged. Of course, the baffle drive device 150 may not be connected to the drive end of the lifting drive device 170. That is, while the lifting drive device 170 drives the cutting table 110 to move in the vertical direction, the position of the friction baffle 120 relative to the cutting table 110 changes.

[0086] In one feasible implementation, the adsorption device 190 pulls the strapping 12 along the first horizontal direction, and the paper stack 11 is not subjected to force in the second horizontal direction. In this design, the limiting component 180 can limit the position of the paper stack 11 only along the first horizontal direction. Specifically, the limiting component 180 includes at least one set of rods, each set including two first guide rods 181 extending from the blanking station to the cutting station. The two first guide rods 181 of each set are respectively disposed on both sides of the cutting table 110 along the first horizontal direction to clamp the paper stack 11, thereby limiting the paper stack 11 along the first horizontal direction. Exemplarily, the limiting component 180 includes two sets of rods, spaced apart along the second horizontal direction, and the strapping 12 can be located between the two sets of rods. Of course, the limiting component 180 may also include second guide rods 182 disposed on both sides of the cutting table 110 along the second horizontal direction to limit the paper stack 11 along the second horizontal direction.

[0087] Exemplarily, the cutting device 100 also includes a discharge bin 1901 disposed below the adsorption device 190. After the adsorption device 190 adsorbs the strapping 12 at the discharge station and causes the strapping 12 to detach from the paper stack 11, the adsorption device 190 releases its adsorption on the strapping 12, and the strapping 12 naturally falls into the discharge bin 1901 for easy recycling. In this embodiment, a first position sensor (not shown) may be disposed above the discharge bin 1901. When the first position sensor detects that the strapping 12 has fallen into the discharge bin 1901, the lifting drive device 170 drives the cutting table 110 to move the paper stack 11 vertically from the discharge station to the cutting station. The first position sensor may be a photoelectric sensor.

[0088] Specifically, the adsorption device 190 includes a first adsorption component 191 and a first adsorption drive 192. The first adsorption component 191 includes multiple first suction cups 1911; the first adsorption drive 192 is connected to the first adsorption component 191 and drives the first adsorption component 191 to reciprocate along a first horizontal direction. In this embodiment, after the strapping 12 of the packaging 10 is cut and moved to the unloading station, the first adsorption drive 192 drives the multiple first suction cups 1911 to move towards the strapping 12 along the first horizontal direction until the first suction cups 1911 adsorb the strapping 12. Then, the first adsorption drive 192 drives the multiple first suction cups 1911 to move the strapping 12 in the opposite direction until the strapping 12 detaches from the paper stack 11. Finally, the first suction cups 1911 release their adsorption of the strapping 12, and the strapping 12 naturally falls into the unloading bin 1901.

[0089] For example, the first adsorption drive 192 includes, but is not limited to, an electric cylinder or a pneumatic cylinder.

[0090] In one feasible implementation, at the unloading station, the cutting table 110 is provided with pads 111 on both sides along the second horizontal direction. The pads 111 are used to support the paper stack 11 located at the unloading station, and a separation gap is formed between the two pads 111, the paper stack 11 located at the unloading station, and the cutting table 110. The height of the separation gap is greater than the thickness of the strapping 12, which effectively prevents the strapping 12 from scattering the paper stack 11 when it comes off, so that the stacking state of the paper stack 11 remains vertical.

[0091] In this embodiment, reference is made to Figure 1As shown, the cutting device 100 also includes two alignment baffles 112 and two alignment drive members 113 that are connected to the alignment baffles 112 in a one-to-one correspondence. One of the two alignment baffles 112 is disposed on the first side of the cutting table 110 along the second horizontal direction, and the other is disposed on the second side of the cutting table 110 along the second horizontal direction. The alignment drive member 113 is used to drive the corresponding alignment baffle 112 to move and limit the paper stack 11 towards the cutting table 110. In this embodiment, after the strapping 12 is removed from the paper stack 11, the lifting drive device 170 drives the cutting table 110 to move the package 10 vertically to the cutting station. The alignment drive device 113 then drives the corresponding alignment baffle 112 to push the corresponding end of the paper stack 11 along the second horizontal direction, forming a clamp. This achieves shaping and limiting of the paper stack 11 along the second horizontal direction, keeping the stack vertical. Then, the alignment drive device 113 is reset, and the pushing device 130 pushes the paper stack 11 onto the unloading table 300, awaiting clamping and transfer by the unloading device 500. Furthermore, after the package 10 is transferred from the loading table 200 to the cutting table 110 at the cutting station, the alignment drive device 113 can also drive the corresponding alignment baffle 112 to push the paper stack 11, adjusting the position of the package 10 along the second horizontal direction so that the pressing block 141 is suitable for pressing against the paper stack 11.

[0092] For example, the alignment drive 113 includes, but is not limited to, a cylinder equipped with a magnetic switch to detect the horizontal position of the alignment baffle 112 in real time.

[0093] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 As shown, the pushing device 130 includes a push plate 131 and a pushing drive member 132 connected to the push plate 131. The pushing drive member 132 can drive the push plate 131 to push the package 10 on the loading table 200 to the cutting table 110 of the cutting station, and make the strapping 12 fit with the friction baffle 120. The pushing drive member 132 can also drive the push plate 131 to push the paper stack 11 on the cutting table 110 of the cutting station to the unloading table 300.

[0094] Specifically, the push plate 131 includes a middle plate 1311 and vertical plates 1312 located on both sides of the middle plate 1311 along a first horizontal direction. The vertical plates 1312 protrude from the middle plate 1311 along the first horizontal direction toward the friction baffle 120. In this embodiment, the middle plate 1311 can be used to push against the strapping 12, or it can not be in contact with the strapping 12. The displacement of the paper stack 11 is pushed by the two vertical plates 1312, which is stable and reliable.

[0095] In one feasible implementation, the bottom end of the vertical plate 1312 protrudes from the middle plate 1311 in the vertical direction, and the bottom end of the vertical plate 1312 is provided with a protrusion 13121. The loading table 200, the cutting table 110 and the unloading table 300 are respectively provided with a relief groove 1101 corresponding to the protrusion 13121. The protrusion 13121 can extend into the relief groove 1101 so that the side of the vertical plate 1312 facing the friction baffle 120 can contact all the trademark papers of the paper stack 11, that is, it can push against all the trademark papers of the paper stack 11, effectively ensuring the stacking stability of the paper stack 11.

[0096] Of course, the top of the vertical plate 1312 can also protrude from the middle plate 1311 along the vertical direction, and this application does not limit it.

[0097] Exemplarily, the push drive 132 includes, but is not limited to, a linear motor and a lead screw slide mechanism. Exemplarily, the push drive 132 also includes a push plate position sensor (not shown), such as a linear displacement sensor or a slotted photoelectric switch, to detect the horizontal position of the push plate 131 in real time.

[0098] In the prior art, the feeding device 400 typically conveys the package 10 directly to the cutting table 110 via a belt conveyor. This method has low positional accuracy and may cause the paper stack 11 to become skewed during conveying, affecting subsequent cutting. In this embodiment, referring to… Figure 5As shown, the feeding device 400 includes a conveyor belt 410, a limiting baffle 420, a second adsorption assembly 430, a second adsorption drive 440, and a horizontal drive 450. The conveyor belt 410 is used to transport the package 10; the limiting baffle 420 is disposed at the unloading end of the conveyor belt 410 and is used to block the package 10; the second adsorption assembly 430 is disposed above the conveyor belt 410 and includes multiple second suction cups 431; the second adsorption drive 440 is connected to the second adsorption assembly 430 and is used to drive the second adsorption assembly 430 to reciprocate vertically; the horizontal drive 450 is connected to the second adsorption drive 440 and is used to drive the second adsorption assembly 430 to move the package 10 along a second horizontal direction to the feeding platform 200. In this embodiment, firstly, the package 10 is placed at the loading end of the conveyor belt 410. The conveyor belt 410 transports the package 10 to its unloading end, causing the long side of the package 10, i.e., one side of the package 10 along the first horizontal direction, to be in contact with the limiting baffle 420. Even if the strapping 12 is loose, the limiting baffle 420 can effectively ensure that the stacked state of the paper stack 11 remains vertical. Secondly, the second adsorption drive 440 is controlled to drive the second adsorption assembly 430 to move vertically toward the package 10 until the second suction cup 431 adsorbs the package 10. After 0, the second adsorption drive 440 drives the second adsorption assembly 430 to move upward and reset; then, the horizontal drive 450 drives the second adsorption assembly 430 to move the package 10 along the second horizontal direction to above the loading platform 200, and then controls the second adsorption drive 440 to drive the second adsorption assembly 430 to move downward, and the second suction cup 431 releases its adsorption on the package 10; finally, the second adsorption drive 440 drives the second adsorption assembly 430 to move upward and reset, and the horizontal drive 450 drives the second adsorption assembly 430 to move horizontally and reset, waiting for the next round of operation.

[0099] Preferably, the second suction cup 431 is used to absorb the strapping 12.

[0100] For example, the second adsorption drive 440 includes, but is not limited to, a cylinder equipped with a magnetic switch to detect the vertical position of the second adsorption assembly 430 in real time.

[0101] Exemplarily, the horizontal drive 450 includes, but is not limited to, a linear motor and a lead screw slide mechanism. Exemplarily, the horizontal drive 450 also includes a horizontal position sensor (not shown), such as a linear displacement sensor or a slotted photoelectric switch, to detect the horizontal position of the second adsorption assembly 430 in real time.

[0102] For example, the package 10 can be placed on the loading end of the conveyor belt 410 by the robotic arm 210, and then the conveyor belt 410 transports the package 10 to its unloading end and abuts against the limiting baffle 420, effectively preventing positional interference between the robotic arm 210 and components such as the limiting baffle 420 and the second adsorption component 430, thus avoiding any impact on the loading operation of the robotic arm 210. The robotic arm 210 can be driven by the multi-degree-of-freedom robotic arm 220, and the robotic arm 210 uses suction cups to adsorb and grasp the package 10.

[0103] For example, the conveyor belt 410 transports the package 10 along a first horizontal direction to ensure a compact structure of the feeding system.

[0104] In one feasible implementation, a second position sensor (not shown) is provided at the limiting baffle 420. When the second position sensor detects a time t after the package 10 has been conveyed to the unloading end of the conveyor belt 410, it controls the second adsorption drive 440 to drive the second adsorption assembly 430 to move vertically toward the package 10. The time t can be 1s-2s to allow sufficient time for the long side of the package 10 to contact the limiting baffle 420, ensuring that the long side of the package 10 is parallel to the first horizontal direction. The second position sensor can be a photoelectric sensor.

[0105] In one feasible implementation, a CCD camera (not shown) is provided at the limiting baffle 420, which can detect whether there is a package 10 on the conveyor belt 410 being transported to the unloading end.

[0106] In one feasible implementation, the loading platform 200 is provided with an end baffle 460 on the side facing away from the conveyor belt 410 along the second horizontal direction. When the horizontal drive member 450 drives the second adsorption assembly 430 to move the package 10 along the second horizontal direction to above the loading platform 200, the short side of the corresponding side of the package 10, that is, the corresponding end of the package 10, can be in contact with the end baffle 460 to achieve the positioning of the package 10 along the second horizontal direction. After the package 10 is transferred to the cutting table 110, the lower pressing block 141 is adapted to press against the paper stack 11.

[0107] For example, a third position sensor (not shown) is provided at the end baffle 460. When the third position sensor detects that the package 10 is above the loading platform 200, it controls the second adsorption drive 440 to drive the second adsorption assembly 430 to move downward, and the second suction cup 431 releases its adsorption on the package 10. The third position sensor can be a photoelectric sensor.

[0108] In this embodiment, reference is made to Figure 1 and Figure 3As shown, the feeding device 500 includes two first clamping plates 510 and a first clamping drive member 520 connected to the two first clamping plates 510. A first limiting groove 511 is provided on the side of the first clamping plate 510 facing the feeding table 300. The two ends of the first limiting groove 511 penetrate the first clamping plate 510 along a first horizontal direction, i.e., the first limiting groove 511 is U-shaped. In this embodiment, when the paper stack 11 is on the feeding table 300, it is located between the two first clamping plates 510. The first clamping drive member 520 drives the two first clamping plates 510 to clamp the two ends of the paper stack 11 along a second horizontal direction, i.e., to limit the paper stack 11 along the second horizontal direction. Both ends of the paper stack 11 along the second horizontal direction are placed within the first limiting groove 511. The first limiting groove 511 limits the vertical position of the paper stack 11 to prevent the paper stack 11 from tilting excessively and causing the trademark paper to scatter.

[0109] For example, the first clamping drive 520 includes, but is not limited to, a cylinder equipped with a magnetic switch to detect the relative position of the two first clamping plates 510 in real time.

[0110] Furthermore, the feeding device 500 includes two second clamping plates 530 and a second clamping drive member 540 connected to the two second clamping plates 530. Two first clamping plates 510 are located between the two second clamping plates 530, and each of the second clamping plates 530 has an extension plate 531 extending towards the feeding table 300 along the first horizontal direction on both sides. A second limiting groove is formed between the second clamping plates 530 and the extension plates 531, and the second limiting groove is U-shaped. In this embodiment, the second clamping drive member 540 drives the two second clamping plates 530 to move towards the paper stack 11 until both ends of the paper stack 11 along the second horizontal direction are respectively placed in the corresponding U-shaped grooves. The extension plates 531 restrict the position of the paper stack 11 along the first horizontal direction to prevent the paper stack 11 from tilting and scattering.

[0111] For example, the second clamping drive 540 includes, but is not limited to, a cylinder equipped with a magnetic switch to detect the relative position of the two second clamping plates 530 in real time.

[0112] This embodiment also provides a cutting method applied to the cutting device 100 described above, referring to... Figure 6 As shown, the cutting method includes the following steps:

[0113] S100, the control pushing device 130 pushes the package 10 along the first horizontal direction until the strapping 12 and the friction baffle 120 are in contact.

[0114] S200, control the pressing device 140 to press the paper stack 11.

[0115] S300, the control baffle drive device 150 drives the friction baffle 120 to reciprocate and rub the strapping 12 in the vertical direction.

[0116] S400, the control cutting drive 162 drives the cutting blade 161 to cut the strapping 12 along the second horizontal direction.

[0117] In one possible implementation, the following step is further included between step S200 and step S300:

[0118] S201, Control the pushing device 130 to detach from the package 10.

[0119] S202, The control baffle drive device 150 drives the friction baffle 120 to descend a distance a.

[0120] In this process, steps S201 and S202 are not sequential. The friction baffle 120 descends a distance a to prevent the binding strap 12 from squeezing the trademark paper located at the top of the paper stack 11 when the friction baffle 120 moves upward, thus effectively preventing the trademark paper from curling up.

[0121] For example, the distance 'a' is 30mm-60mm, such as 50mm. Of course, the distance 'a' can also be other sizes, and this application does not impose any restrictions on it.

[0122] For example, in step S201, the control pusher 130 moves 5mm-15mm, for example 10mm, away from the package 10 along the first horizontal direction.

[0123] Furthermore, step S300 specifically includes the following steps:

[0124] S310, the control baffle drive device 150 drives the friction baffle 120 to descend a distance b;

[0125] S320, the control baffle drive device 150 drives the friction baffle 120 to rise a distance b.

[0126] In this embodiment, the friction baffle 120 is driven to move back and forth in the vertical direction once by the baffle driving device 150 to ensure that the strapping 12 is suitable for cutting by the cutting blade 161. This is convenient and quick, effectively ensuring that the strapping 12 is completely cut and that the label paper is not easily damaged.

[0127] For example, the distance b is 100mm-120mm, such as 110mm. Of course, the distance b can also be other sizes, and this application does not impose any restrictions.

[0128] In this embodiment, after step S400, the following step is also included:

[0129] S500, the control lifting drive device 170 drives the cutting table 110 to move the package 10 vertically from the cutting station to the unloading station.

[0130] S600, the adsorption device 190 adsorbs the strapping tape 12 and drives the strapping tape 12 to be pulled away from the paper stack 11.

[0131] S700, control the lifting drive device 170 to drive the cutting table 110 to move the paper stack 11 to the cutting station, and control the pushing device 130 to push the paper stack 11 from the cutting table 110 to the unloading table 300.

[0132] S800, the control feeding device 500 clamps and transfers the paper stack 11 on the feeding table 300.

[0133] It is understood that the specific execution process of each device in the above steps can be found in the aforementioned relevant introduction, and will not be repeated here.

[0134] In one possible implementation, the above Figure 6 The cutting method shown can be executed by a controller. The controller may include, but is not limited to, a Programmable Logic Controller (PLC). The controller, in conjunction with multiple position sensors, can ensure the accuracy of the cutting equipment's movements.

[0135] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
