Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and in particular to a gauze multi-channel three-dimensional aggregate packaging system. Background Art

[0002] From production to cartoning, sheet materials generally need to go through the following processes: collection and stacking, carton opening, sheet material cartoning, and carton lid closing.

[0003] In the process of collecting and processing sheet materials, especially for those sheet products with thick thickness and soft texture, such as cotton sheets, gauze, etc., the problem of stacked materials tipping over and dumping often occurs. This is because when the materials are piled too high, their stability decreases, which can easily lead to dumping. In order to adapt to the speed of the front-end incoming materials and avoid the tipping over and dumping of materials during the processing process, it is necessary to improve the existing material collection and processing equipment. The existing material collection equipment is usually a one-level silo, which directly stacks the sheet materials together to form a higher material pile, which increases the risk of material dumping. Therefore, it is necessary to design a new type of material collection and processing equipment to improve the stability of material stacking, reduce the risk of dumping, and be able to adapt to the speed of the front-end incoming materials.

[0004] Existing automatic carton opening devices are typically designed for specific carton sizes and shapes, and have limited adaptability to different sizes and shapes. Furthermore, many such devices can damage the carton during opening, impacting the packaging quality and effectiveness. Therefore, achieving both versatility and efficiency in automatic carton opening devices is a key challenge facing current technology.

[0005] Fluffy materials like cotton pads and gauze are often placed in cartons. However, these materials often push the lid open. Therefore, currently, manual capping is the only way to do it. Operators must use one hand to press the fluffy material into the box while using the other to close the lid. While effective, manual capping is inefficient and cannot adapt to the pace of automated production lines. Furthermore, assigning multiple operators to handle the process increases production costs.

[0036] A conveying device, used for conveying the paper box in a transverse direction;

[0037] The folding ear mobile platform comprises a platform plate capable of moving laterally, a folding ear telescopic seat mounted on the platform plate and capable of moving longitudinally, and a pair of folding ear plates mounted on the folding ear telescopic seat and capable of rotating; the rotation axis direction of the folding ear plates is longitudinal;

[0038] The folding ear guardrail is fixed horizontally on the bearing platform, higher than the box body and lower than the folding ear plate;

[0039] The cover-locking mechanism includes a cover-pressing block that can move longitudinally and is used to tilt the upper cover forward, a cover-locking support rod that can be extended and retracted laterally and is used to extend under the upper cover after tilting forward, a cover-locking baffle that can move vertically and is used to cooperate with the cover-locking support rod to bend the end of the upper cover, and a cover-locking pressure plate that can be flipped laterally and is used to press the bent part of the end of the upper cover into the box body.

[0040] Furthermore, the conveying device includes a pair of wheels arranged axially in the vertical direction, a belt wrapped around the wheels, a pair of levers fixed on the belts, and a conveying motor that drives the wheels to rotate; the paper box is placed between the pair of levers; the wheels include an upper wheel and a lower wheel, and the upper wheel and the lower wheel are connected in a variable height manner.

[0041] Furthermore, the main conveying line has a plurality of transversely extending conveying channels; the collecting device has a plurality of collecting channels corresponding to the conveying channels, and each collecting channel has a group of primary silos, secondary silos and tertiary silos.

[0042] Compared with the prior art, the beneficial technical effects of the present invention are:

[0043] After the sheet materials are put into the primary silo piece by piece, a smaller amount of stacked materials is formed, which are then transferred multiple times through the secondary silo. Multiple smaller amounts of stacked materials form a larger amount of stacked materials in the tertiary silo. The stacked materials in the tertiary silo are protected by the tertiary silo guard and the tertiary silo push plate to prevent the stacked materials from tipping over. The present invention is suitable for collecting sheet products with thicker thickness and softer texture. Softer texture (such as cotton sheets) are prone to tipping over when the thickness is too high. The single small amount and multiple collection method is adopted to effectively solve the tipping problem, and the speed can also adapt to the incoming material speed of the previous section.

[0044] The present invention places vertically stacked cartons in a carton hopper, and limits the position of the cartons by means of push plates and blocking blocks. Due to the high flexibility of the cartons, when the frontmost cartons are sucked by the material-picking suction cup on the material-picking module, the frontmost cartons can be sucked out of the carton hopper; when the material-picking module picks up the cartons, the box-opening suction cup needs to rotate to avoid, and after the material-picking suction cup picks up one side of the cartons, the box-opening suction cup rotates back to pick up the other side of the cartons, and then the material-picking suction cup moves toward the side away from the box-opening suction cup to open the cartons. Since the material-picking suction cup and the opening and closing suction cup in the present invention are arranged vertically, when the vertical size of the cartons is small, only the vacuum passages of some of the material-picking suction cups and the box-opening suction cups are opened, and the other passages are closed; when the vertical size of the cartons is large, the passages of all the material-picking suction cups and the box-opening suction cups can be opened, thereby realizing the opening of cartons of multiple specifications. The bottom of the compressed carton is thicker than the top, so the end of the vertically stacked carton is tilted. The push plate in the present invention can not only control the force of the compressed carton stack by moving horizontally, but also adjust the angle to fit the angle of the carton stack, avoiding low pressure on the top and high pressure on the bottom, which will push the carton out of the carton hopper.

[0045] The present invention provides a flap cover for fluffy materials after they are loaded into a carton. The flap cover is provided with a movable platform that can move downstream with the carton for a distance until it reaches the flap guardrail. During this process, the flap plate always presses the flap to prevent the fluffy material inside the carton from bouncing up. After the carton moves to the point where the flap guardrail is lowered, the flap is pressed down. At this point, the flap plate can retract, the flap platform resets, and the flap of the next carton is pressed down. Furthermore, the present invention achieves automated flapping by means of the flap support rod, flap baffle, and flap pressure plate, which cooperate to bend the end of the carton top cover and press it into the carton, thereby achieving automated flapping.

[0063] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0064] The gauze in the present invention is made of non-woven fabric, which is a sheet material with a relatively large thickness and a relatively high flatness. It is easy to fall over when stacked at a high height.

[0065] like Figure 1 As shown, the aggregate packaging system of the present invention includes a main conveyor line 10, a gripping device 50, a material collecting device 30, a box opening device 40, a material taking robot 60, and a capping device 20.

[0066] The structure of the main conveyor line is that the motor drives the conveyor wheel to rotate, which in turn drives the belt wrapped around the conveyor wheel to rotate, realizing the horizontal conveyance of the gauze.

[0067] The main conveyor line is provided with a metal detector 71, a visual inspection device 72, and a rejection device 73; the metal detector is used to detect metal residues in the gauze, the visual inspection device is used to detect the qualification of the gauze, and the rejection device rejects gauze with metal residues and unqualified gauze based on the feedback information of the metal detector and the visual inspection device. The main conveyor line in this embodiment is formed by a combination of multiple conveying sections. The rejection device includes a vertically arranged cylinder and a vertical plate fixedly connected to the moving end of the cylinder. The rejection device is arranged between the two conveying sections. When the gauze to be rejected passes between the two conveying sections, the vertical plate of the rejection device moves downward, pressing the gauze between the two conveying sections downward and leaving the main conveyor line, thereby achieving material rejection.

[0068] like Figure 2 As shown, the grabbing device includes a grabbing motor arranged in a longitudinal direction, a rocker arm 51 fixedly connected to the movable end of the grabbing motor, a rocker rod 52 rotatably connected to the rocker arm and arranged in the longitudinal direction, and a grabbing suction cup 53 fixedly connected to the rocker rod. When the grabbing motor rotates, it can drive the rocker arm to rotate. Since the rocker arm is rotatably connected to the rocker rod, when the rocker arm rotates, the rocker rod can perform a lateral reciprocating motion, and drive the grabbing suction cup to perform a lateral motion, thereby grabbing the gauze on the main conveyor line and transferring it to the collecting device.

[0069] like Figure 3 As shown, the material collecting device includes a first-level silo 311, a second-level silo 312, a third-level silo 313, a first-level silo bottom support plate 322, a first-level silo rib 392, a second-level silo bottom support plate 342, a second-level silo push plate 332, a pressure plate 352, a support plate 362, a third-level silo push plate 372, a third-level silo rib 383, a first cylinder 391, a second clamping cylinder 321, a third cylinder 331, a fourth cylinder 351, a fifth cylinder 371, a sixth cylinder 381, a seventh cylinder 382, ​​an eighth cylinder 361, and a ninth cylinder 341.

[0070] In the material collection device, except for the second clamping cylinder 321, all other cylinders are linear cylinders, including a cylinder body and a piston rod. The cylinder body is the fixed end of the cylinder, and the piston rod is the movable end of the cylinder. The second clamping cylinder 321 includes a cylinder body and a rotating working part, and the rotating working part is the rotating end.

[0071] In the present invention, a plurality of first-level silos 311 , second-level silos 312 , and third-level silos 313 can be provided along the longitudinal direction as needed to improve efficiency.

[0072] In this embodiment, the first-level silo 311, the second-level silo 312, and the third-level silo 313 are arranged in a stepped manner, with the first-level silo 311 located at the top, the second-level silo 312 located in the middle, and the third-level silo 313 located at the bottom.

[0073] like Figures 3 to 11As shown, in the previous process, the gauze 2 will be stacked and placed in the first-level silo 311. The first-level silo 311 is relatively deep and is used to cache a small amount of gauze 2. When the gauze 2 in the first-level silo 311 reaches a certain amount, it will enter the second-level silo 312 and then be transferred to the third-level silo 313 through the second-level silo 312. While the second-level silo 312 is transferring, the first-level silo 311 can store the next batch of materials, which will not cause the accumulation of materials in the previous process. When the second-level silo 312 is transferred to the third-level silo 313, the third-level silo 313 will not be transferred to the next process immediately. The second-level silo 312 will transfer multiple batches of gauze 2 and place them on a pile of gauze 2 in the third-level silo 313. After reaching a certain amount, it will be transferred to the end of the third-level silo 313 for use in the next process. The first-level silo 311 of the present invention can store the gauze 2 of the previous process at any time, so the speed of the entire production line will not be delayed. Moreover, the materials transferred multiple times by the second-level silo 312 will be stacked and placed in the third-level silo 313. The subsequent process has fewer picking actions, high efficiency, and can ensure that the stacked gauze 2 will not fall over.

[0074] The first cylinder 391 is arranged vertically, and the movable end of the first cylinder 391 is fixedly connected to the primary silo rib 392. The primary silo rib 392 extends downwardly into the side of the primary silo 311 to protect the stacked materials in the primary silo 311 and prevent the stacked materials from tipping over.

[0075] The first-level silo bottom support plate 322 is located at the bottom of the first-level silo 311, and the rotating end of the second clamping cylinder 321 is fixedly connected to the first-level silo bottom support plate 322. The second clamping cylinder 321 can drive the base plate of the first-level silo 311 to rotate, and the stacked gauze 2 on the first-level silo bottom support plate 322 can fall into the second-level silo 312.

[0076] The third cylinder 331 is arranged horizontally, and the secondary silo push plate 332 is fixedly connected to the movable end of the third cylinder 331. When the gauze 2 at one end of the secondary silo 312 needs to be pushed to the other end, the first cylinder 391 drives the primary silo retaining edge 392 to rise, and the third cylinder 331 drives the secondary silo push plate 332 to move horizontally, pushing the gauze 2 to the other end and placing it on the secondary silo bottom support plate 342.

[0077] like Figures 3 to 11As shown, the ninth cylinder 341 is arranged horizontally, and the moving end of the secondary silo bottom support plate 342 is fixedly connected to the moving end of the ninth cylinder 341; when the gauze 2 needs to be transferred from the secondary silo 312 to the tertiary silo 313, the support plate 362 rises to the bottom of the secondary silo bottom support plate 342, and the pressure plate 352 moves to above the gauze 2, and then the ninth cylinder 341 retracts, driving the secondary silo bottom support plate 342 to retract, and the gauze 2 falls above the support plate 362, and the pressure plate 352 and the support plate 362 descend at the same time, and due to the action of the pressure plate 352, the gauze 2 will not flip over and tip over during the descent of the support plate 362. At this time, there is less gauze 2 between the pressure plate 352 and the support plate 362, and it is necessary to transfer through the secondary silo 312 multiple times to increase the amount of gauze 2 between the pressure plate 352 and the support plate 362. Before each subsequent secondary silo 312 transports gauze 2, the pressing plate 352 rises, and the ninth cylinder 341 extends, driving the secondary silo bottom support plate 342 to extend to the connection between the secondary silo 312 and the tertiary silo 313. When the third cylinder 331 drives the secondary silo push plate 332 to push the next batch of gauze 2 to the secondary silo bottom support plate 342, the pressing plate 352 descends, and the secondary silo bottom support plate 342 retracts. This batch of gauze 2 falls on the previous batch of gauze 2 on the support plate 362, and then the pressing plate 352 and the support plate 362 descend at the same time; after repeating the above process several times, the gauze 2 between the pressing plate 352 and the support plate 362 reaches a specific number.

[0078] The fourth cylinder 351 is arranged vertically, with the pressure plate 352 fixedly connected to the movable end of the fourth cylinder 351. The eighth cylinder 361 is arranged vertically, with the support plate 362 fixedly connected to the movable end of the eighth cylinder 361. The fifth cylinder 371 is arranged horizontally, with the third-stage silo push plate 372 fixedly connected to the movable end of the fifth cylinder 371. The sixth cylinder 381 is arranged horizontally, with the seventh cylinder 382 fixedly connected to the movable end of the sixth cylinder 381; the seventh cylinder 382 is arranged vertically, with the third-stage silo retaining edge 383 fixedly connected to the seventh cylinder 382.

[0079] like Figures 3 to 11As shown, after the amount of gauze 2 between the pressing plate 352 and the supporting plate 362 reaches a specific amount, the pressing plate 352 rises and the supporting plate 362 falls, and the seventh cylinder 382 drives the third-level silo rib 383 to rise and pass through the opening below the third-level silo 313. The gauze 2 previously located between the pressing plate 352 and the supporting plate 362 is now located between the third-level silo push plate 372 and the third-level silo rib 383. The fifth cylinder 371 drives the third-level silo push plate 372 to move laterally. At the same time, the sixth cylinder 381 drives the seventh cylinder 382 and the third-level silo rib 383 to move laterally, that is, the third-level silo push plate 372 and the third-level silo rib 383 remain relatively stationary to prevent the gauze 2 between them from falling over, and then drives the gauze 2 to the other end of the third-level silo 313. Then the tertiary silo retaining edge 383 is lowered, and one end of the tertiary silo 313 away from the secondary silo 312 is an open structure. After the tertiary silo retaining edge 383 is lowered, the next process can take away the stacked gauze 2.

[0080] like Figure 12 and Figure 13 As shown, the carton opening device of the present invention includes a carton material bin 44 , a carton pressing device 41 , a blocking block 45 , a material taking module 42 and a carton opening module 43 .

[0081] The carton hopper 44 is arranged horizontally for placing the vertically stacked cartons 1, which are in a compressed state and are in sheet form. The bottom of the compressed cartons 1 is thicker than the top, so the ends of the vertically stacked cartons are tilted.

[0082] like Figure 12 and Figure 13 As shown, the carton pressing device 41 includes a pair of rollers 411, a belt 413 that passes around the rollers 411, a pressing motor 412 that drives the rolling rotation, and a push plate 414 that is fixedly connected to the belt 413. When the pressing motor 412 rotates, it can drive the push plate 414 to translate in the carton hopper 44, thereby tightening the carton at the end. Because the bottom of the compressed carton is thicker than the top, the end of the vertically stacked carton is tilted. Therefore, in a further improvement, the push plate 414 is variable in angle, and the push plate 414 forms a certain angle with the vertical direction, and the tilt direction is the same as the tilt direction of the end of the stacked carton. This can prevent the lower part of the thicker carton stack from being pushed out of the carton hopper 44.

[0083] like Figure 12 and Figure 13As shown, the picking module 42 includes a horizontally arranged picking cylinder 421, a picking plate 422 fixedly connected to the movable end of the picking cylinder 421 and arranged vertically, and a plurality of picking suction cups 423 arranged vertically on the picking plate 422. The picking cylinder 421 can drive the picking suction cups 423 to move horizontally, and the picking suction cups 423 pick up the frontmost carton. Although the frontmost carton is blocked by the blocking block at the front end of the carton bin 44, the blocking block only protrudes a short distance in the longitudinal direction and will not block the entire carton. In addition, the carton has great flexibility. When the frontmost carton is sucked, the picking cylinder 421 drives the picking suction cups 423 to retract, and the frontmost carton will break free from the restraint of the blocking block and leave the carton bin 44.

[0084] like Figure 12 and Figure 13 As shown, the box opening module 43 includes a rotating motor 431, an offset rod 432 fixedly connected to the rotating end of the rotating motor 431 and arranged horizontally, a vertically arranged box opening plate 433, and a plurality of box opening suction cups 434 arranged vertically on the box opening plate 433. When the picking module 42 picks up the frontmost carton, the box opening plate 433 and the box opening suction cup 434 cannot be on the movement trajectory of the material picking suction cup 423. The rotating motor 431 is required to drive the offset rod 432 to rotate, and then drive the box opening plate 433 to rotate to other positions, which will not affect the movement of the material picking suction cup 423; after the material picking suction cup 423 completes picking up the material, the material picking suction cup 423 will move in the direction away from the carton hopper 44. At this time, the rotating motor 431 rotates in the opposite direction to return the box opening plate 433 and the box opening suction cup 434 to their original positions. At this time, the box opening suction cup 434 sucks the side of the carton away from the material picking suction cup 423, and then the material picking cylinder 421 drives the material picking suction cup 423 to move toward the side away from the carton suction cup 434 to open the carton and achieve box opening.

[0085] Figure 14 The front-to-back direction is the longitudinal direction.

[0086] like Figures 14 to 17 As shown, the cover-closing device in the present invention is used to automatically close the cover of the paper box 1, and the paper box 1 includes a box body 11, ears 12, and an upper cover 13; the cover-closing device includes: a carrying platform 25, a conveying device 24, an ear folding moving platform 21, an ear folding guardrail 23 and a cover-closing mechanism 22.

[0087] The carrying platform 25 is the installation platform of the entire cover device and is used to carry other devices.

[0088] like Figure 14 and Figure 15As shown, the conveying device 24 is used to convey the carton 1. The conveying device 24 includes a pair of vertically axially arranged rotating wheels, a belt 242 that passes around the rotating wheels, a pair of levers 243 fixed to the belt 242, and a conveying motor 241 that drives the rotating wheels to rotate. The carton 1 is placed between the pair of levers 243. When the conveying motor 241 rotates, it drives the rotating wheels and belt 242 to move, and the pair of levers 243 on the belt 242 in turn drives the carton 1 to move. The rotating wheels include an upper rotating wheel and a lower rotating wheel. The upper and lower rotating wheels are connected in a variable height manner, for example, by a screw. The upper rotating wheel is connected to the shaft sleeve of the screw, and the lower rotating wheel is connected to the body of the screw. When the screw rotates, the vertical distance between the upper and lower rotating wheels can be adjusted. In turn, the distance between the upper and lower levers can be adjusted to accommodate carton 1 of different heights.

[0089] like Figure 14 and Figure 15 As shown, the folding ear mobile platform 21 includes a platform plate 214, a folding ear telescopic seat 217, a folding ear plate 218, a guide rail 211, a rack 212, a gear, a transverse drive motor 213, a folding ear drive cylinder 215, and a rotating cylinder 219. The guide rail 211 and the rack 212 are mounted on the carrying platform 25, the platform plate 214 is slidably engaged with the guide rail 211, the transverse drive motor 213 is mounted on the platform plate 214, and the gear is mounted on the rotating end of the transverse drive motor 213, and the gear is engaged with the rack 212; when the transverse drive motor 213 rotates, it drives the gear to rotate, and through the engagement of the gear and the rack 212, the platform plate 214 is driven to move along the guide rail 211. The guide rail 211 is arranged in a transverse direction, so the platform plate 214 can move in a transverse direction. The ear-folding drive cylinder 215 is fixedly mounted on the platform plate 214, specifically on the cylinder fixing plate 216. The cylinder fixing plate is vertically arranged and fixedly mounted on the platform plate 214. The ear-folding telescopic seat 217 is fixedly connected to the moving end (i.e., piston rod) of the ear-folding drive cylinder 215. The ear-folding drive is arranged longitudinally, and the ear-folding telescopic seat 217 can move longitudinally. There are two rotating cylinders 219, both of which are mounted on the ear-folding telescopic seat 217. The ear-folding plate 218 is fixedly connected to the rotating end of the rotating cylinder 219. When the rotating cylinder 219 rotates, the ear-folding plate 218 is driven to rotate, thereby bending the two ears 12 of the carton 1 inward. Then the conveying device 24 conveys the carton 1 downstream, and the ear-folding movable platform 21 can move a distance downstream together with the carton 1 until it moves to the ear-folding guardrail 23. During this process, the ear-folding plate 218 always presses the ear 12 to prevent the fluffy material in the carton 1 from bouncing the ear 12. After the carton 1 moves to the point where the ear-folding guardrail 23 is lowered, it can press the ear 12. At this time, the ear-folding plate 218 can be retracted, the ear-folding movable platform 21 is reset, and the ear 12 of the next carton 1 is pressed down again.

[0090] like Figure 14 and Figure 15 As shown, in order to achieve the above-mentioned effect, the folding ear guardrail 23 needs to be higher than the box body 11 and lower than the folding ear plate 218; because when the folding ear plate 218 is retracted, it is necessary to drive the folding ear plate 218 to flip upward to the vertical position by rotating the cylinder 219 to avoid interference between the folding ear plate 218 and the upper cover 13 when the folding ear plate 218 is retracted. If the folding ear guardrail 23 is higher than the folding ear plate 218, the vertical folding ear plate 218 will interfere with the folding ear guardrail 23 when it is retracted, so the folding ear guardrail 23 needs to be higher than the box body 11, but lower than the folding ear plate 218.

[0091] like Figure 14 and Figure 15 As shown, the cover-locking mechanism 22 includes a cover-locking block 224, a cover-locking support rod 227, a cover-locking baffle 229, a cover-locking pressure plate 225, a first cover-locking cylinder 222, a second cover-locking cylinder 221, a second rack 223, a second gear, a cover-locking support rod cylinder 226, and a cover-locking baffle cylinder 228. The cover-locking block 224 is fixedly connected to the first cover-locking cylinder 222, which is arranged longitudinally. When the first cover-locking cylinder 222 extends, it drives the cover-locking block 224 to extend, thereby tilting and bending the upper cover 13 forward. The cover-locking support rod 227 is fixedly connected to the movable end of the cover-locking support rod cylinder 226, which is arranged transversely and can drive the cover-locking support rod 227 to move transversely. The cover-locking baffle 229 is fixedly connected to the movable end of the cover-locking baffle cylinder 228. The cover-locking baffle cylinder 228 is arranged vertically and can drive the cover-locking baffle 229 to move vertically. The second rack 223 is fixedly connected to the movable end of the second cover-locking cylinder 221. The second gear meshes with the second rack 223, and the second gear is fixedly connected to the cover-locking pressure plate 225. The rotation axis of the second gear is oriented horizontally. When the second cover-locking cylinder 221 drives the second rack 223 to move, the second gear drives the cover-locking pressure plate 225 to rotate.

[0092] After the cover pressing block 224 bends the upper cover 13 forward, the cover-locking support rod cylinder 226 drives the cover-locking support rod 227 to move below the upper cover 13. Then, the cover-locking baffle cylinder 228 drives the cover-locking baffle 229 to move downward, bending the end of the upper cover 13 downward to form a bent portion 131. At this time, the cover-locking support rod 227 moves horizontally and disengages from the bottom of the upper cover 13. The cover-locking pressure plate 225 rotates and presses the upper cover 13 downward, pressing the bent portion into the box body 11, completing the cover-locking.

[0093] like Figure 17As shown, it is worth noting that before the cover pressing plate 225 flips down to press the upper cover 13, the cover support rod 227 needs to move horizontally to avoid blocking the downward movement of the upper cover 13; but the folding ear guardrail 23 is always located above the box body 11 and below the upper cover 13, so that the ear 12 can be continuously pressed to prevent the ear 12 from being ejected by the material during the process of closing the cover 13. Since the folding ear guardrail 23 is in the form of a sheet, even if the folding ear guardrail 23 is located below the upper cover 13, it will not affect the closing of the upper cover 13. After the closing is completed, the cover pressing block 224, the cover pressing plate 225 and the cover baffle 229 are reset, and the carton 1 that has completed the closing moves horizontally to the next process under the push of the conveying device 24. During this process, the carton 1 will separate from the folding ear guardrail 23, but since the folding ear guardrail 23 is set horizontally and is in the form of a sheet, it will not hinder the carton 1 from moving horizontally.
