Description

Technical Field

[0001] The present invention relates to the technical field of woodworking packaging machinery, and in particular to a compact device for servo adjustment and transportation of cardboard positions. Background Art

[0002] In the woodworking industry, panel furniture, bed frames, etc. need to be packaged after production and processing, which plays a very important role in the storage, transportation and sales of the products.

[0003] Since there are multiple series of product types and sizes, in the actual production process, the size of the packaging paper must be matched according to the actual size of the product.

[0004] Currently, existing automated carton folding equipment can fold cartons of various sizes. This requires that the reference of the carton be adjusted to a specified position before entering the carton folding equipment, such as using the crease position on one side as a reference. However, the carton folding equipment itself cannot automatically adjust the crease position of the carton. This work still requires operators to manually position cartons of different sizes.

[0005] This process will lead to three problems:

[0006] 1. The operators have high workload and monotonous and repetitive work can easily lead to fatigue and safety accidents;

[0007] 2. The speed at which the operator adjusts the paperboard will directly affect the efficiency of the entire production line. Once the operator leaves his post, the subsequent processes will be unable to proceed;

[0008] 3. According to the different sizes of cardboard, the position is adjusted manually. The position accuracy can only rely on the personal proficiency of the operator, and the quality of the carton cannot be guaranteed. Summary of the Invention

[0055] The present invention provides a compact device for servo-controlled cardboard position adjustment and conveying. The device is installed at one end of a cardboard conveyor, adjacent to the cardboard conveyor, and is mounted across and above the conveyor. Regardless of the cardboard's size, the device automatically and accurately positions the cardboard in both its width and length, moving it precisely to the crease reference position required by the automatic box folding machine in the subsequent folding process, preparing it for subsequent folding operations. This device perfectly solves the problem of inefficient cardboard alignment and secondary damage caused by manual cardboard movement.

[0056] The compact device for servo adjustment and conveying of cardboard position of the present invention includes a frame 1, a cardboard blocking mechanism 5, a cardboard position adjustment mechanism 2, a pressure wheel mechanism 4 and a pressure roller conveying mechanism 3, and the cardboard blocking mechanism 5, the cardboard position adjustment mechanism 2, the pressure wheel mechanism 4 and the pressure roller conveying mechanism 3 are all installed on the frame 1.

[0057] The frame 1 is closely arranged at one end of the paperboard conveyor and spans the paperboard conveyor. The frame 1 is used to fix and support the paperboard blocking mechanism 5, the paperboard position adjustment mechanism 2, the pressure wheel mechanism 4 and the pressure roller conveying mechanism 3.

[0058] The cardboard blocking mechanism 5 is used to block the cardboard on the cardboard conveyor to position it in the conveying direction. The cardboard position adjustment mechanism 2 is used to move the cardboard that has stopped moving on the cardboard conveyor to a specified position in the width direction of the cardboard. The pressure wheel mechanism 4 is used to press the cardboard on the pressure roller conveying mechanism 3, and the pressure roller conveying mechanism 3 is used to convey the cardboard to the next workstation.

[0059] Specifically, the cardboard blocking mechanism 5 is installed on the pressing wheel mechanism 4, the pressing wheel mechanism 4 and the pressure roller conveying mechanism 3 are both installed on the frame leg 110 of the frame 1, the pressing wheel mechanism 4 is located above the pressure roller conveying mechanism 3, and the cardboard position adjustment mechanism 2 is installed on the top of the frame 1.

[0060] The cardboard position adjustment mechanism 2 includes a movable frame 210 movably arranged on the top of the frame 1 through a movable frame transmission mechanism 220, a sponge suction cup lifting mechanism 230 fixed on the movable frame 210, a suction cup fixing member 234 fixed to the bottom of the sponge suction cup lifting mechanism 230, sponge suction cups 235 fixed to both ends of the suction cup fixing member 234, and a cardboard edge flattening mechanism 240 arranged on both sides of the sponge suction cup 235.

[0061] The movable frame 210 is a rectangular frame formed by welding square tubes. The movable frame 210 can move laterally on the top of the frame 1 under the drive of the movable frame transmission mechanism 210, thereby driving the sponge suction cup lifting mechanism 230, the sponge suction cup 235 and the cardboard edge flattening mechanism 240 installed thereon to move laterally synchronously.

[0062] The mobile frame transmission mechanism 210 includes a support frame 224 fixed to the mobile frame 210, a frame drive motor 222 fixed to the support frame 224, a gear 223 provided on the output shaft of the frame drive mechanism 222, and a rack 140 fixed to one side of the top of the frame 1. The gear 223 meshes with the rack 140. When the frame drive motor 222 is activated, the gear 223 meshes with the rack 140, thereby driving the mobile frame 210 to move laterally along the rack 140. The frame drive motor 222 is also equipped with a planetary reducer 221.

[0063] Preferably, a sliding block 211 is further fixed to the bottom of the mobile frame 210, and a guide rail 130 parallel to the rack 140 is fixed to the top of the frame 1. The guide rail 130 is located on the opposite side of the rack 140, and the sliding block 211 is clamped on the guide rail 130 and can slide along the guide rail 130. By providing the sliding block 211 at the bottom of the mobile frame 210 and the guide rail 130 at the top of the frame 1, the sliding block 211 is clamped on the guide rail 130, which not only plays a guiding role, but also increases the stability of the lateral movement of the mobile frame 210, making the mobile frame 210 move more smoothly.

[0064] Preferably, stoppers 150 are further provided on both sides of the top of the frame 1 , and the stoppers 150 can form hard limits to prevent the paperboard position adjustment mechanism 2 from colliding with other structures when moving laterally.

[0065] The sponge suction cup lifting mechanism 230 includes a first support member 232 fixed to the moving frame 210 , a suction cup lifting cylinder 231 fixed to the first support member 232 , and a first connecting member 233 fixed to the end of the piston rod of the suction cup lifting cylinder 231 .

[0066] The first support member 232 is fixed to the mobile frame 210 by bolts and other fasteners, and is used to fix and support the suction cup lifting cylinder 231. The piston rod of the suction cup lifting cylinder 231 passes vertically downward through the first support member 232 and is fixed to the first connecting member 233. The suction cup lifting cylinder 231 can provide power in the up and down directions, expanding the vertical stroke of the sponge suction cup lifting mechanism 230. The first connecting member 233 is a U-shaped structure, which is clamped in the middle position of the suction cup fixing member 234 and fixed to the suction cup fixing member 234 by bolts and other fasteners. The two sponge suction cups 235 are respectively fixed to the two ends of the suction cup fixing member 234 by two L-shaped angle brackets. When the suction cup lifting cylinder 231 is started, the suction cup lifting cylinder 231 drives the first connecting member 233 and the suction cup fixing member 234 to move the two sponge suction cups 235 up and down.

[0067] The suction cup fixture 234 is located diagonally below and parallel to the mobile frame 210. A suction cup lift slider 237 is mounted on the side of the suction cup fixture 234 facing the mobile frame 210, and a suction cup lift guide rail 236 is mounted on the corresponding side of the mobile frame 210. The suction cup lift slider 237 is movably mounted within the suction cup lift guide rail 236. The provision of the suction cup lift slider 237 on the suction cup fixture 234 and the suction cup lift guide rail 236 on the mobile frame 210 not only guides the up and down movement of the sponge suction cup 235 but also increases the stability of the up and down movement of the sponge suction cup 235, making the up and down movement of the sponge suction cup 235 more stable.

[0068] Two cardboard edge flattening mechanisms 240 are provided, one on each side of the sponge suction cup 235. These mechanisms include a second connecting member 244, a second support member 242, a flattening cylinder 241, and a pressure rod 243. Two second connecting members 244 are provided, each secured to one side of the top of the left and right sponge suction cups 235. A second support member 242 is secured to the side of each second connecting member 244, and a flattening cylinder 241 is secured to each second support member 242. The piston rod of each flattening cylinder 241 extends vertically downward through the second support member 242. The ends of the pressure rod 243 are secured to the piston rods of the left and right flattening cylinders 241, respectively. When the left and right flattening cylinders 241 are activated, the piston rods of the left and right flattening cylinders 241 can drive the pressing rod 243 to move up and down, thereby flattening the cardboard with raised edges that have not entered the pressing wheel and roller mechanism, avoiding subsequent interference and making it easier for the sponge suction cup 235 to absorb the cardboard.

[0069] In this embodiment, the flattening cylinder 241 is a pen-shaped cylinder, and the first support member 232 , the second support member 242 , the first connecting member 233 and the second connecting member 244 are all sheet metal parts.

[0070] The pressing roller mechanism 4 includes a bracket 312 fixed to the two frame legs 110 of the frame 1, a frame lifting cylinder 311 fixed to the bracket 312, a pressing roller assembly fixing frame 313 with its ends connected to the piston rods of the two frame lifting cylinders 311, and multiple pressing roller assemblies 320 fixed within the pressing roller assembly fixing frame 313. The frame lifting cylinder 311 can raise or lower the entire pressing roller mechanism 4 as a whole to ensure that the cardboard can smoothly enter the pressing roller and roller structure. After the entire pressing roller mechanism 4 is lowered, the pressing roller assembly 320 will start to operate.

[0071] A frame guide rail 314 is fixed to the side of the bracket 312 facing the pressing roller assembly fixing frame 313, and a frame slider 315 is fixed to the outer side of the end of the pressing roller assembly fixing frame 313, which is clamped on the frame guide rail 314. By providing the frame guide rail 314 and the frame slider 315, the entire pressing roller mechanism 4 can be guided to rise or fall as a whole.

[0072] After the position of the cardboard on the conveyor is accurately moved to the crease reference position required by the automatic box folding machine in the subsequent box folding process by the cardboard position adjustment mechanism 2, the frame lifting cylinder 311 drives the entire pressing wheel mechanism 4 to move downward, and then the system controls the movement of the pressing wheel assembly 320 at the corresponding position according to the width of the cardboard, pressing the cardboard tightly on the pressure roller conveyor mechanism 3.

[0073] The pressure roller assembly 320 includes two pressure roller brackets 324 fixed on the pressure roller assembly fixing frame 313, a pressure roller cylinder 321 fixed to the top of the pressure roller bracket 324 through an ear shaft bracket 325 and whose piston rod passes through the pressure roller bracket 324, a pressure roller 322 connected to the piston rods of the two pressure roller cylinders 321 through a rotating shaft 323, and a rocker rod 326, one end of the rocker rod 326 is connected to the rotating shaft 323, and the other end is connected to the rocker rod fixing part 327 fixed on the inner side of the pressure roller bracket 324. When the pressing roller cylinder 321 is started, the piston rod of the pressing roller cylinder 321 moves the pressing roller 322 downward to press the cardboard. At the same time, since the rotating shaft 323 is fixed to the swing rod fixing part 327 on the inner side of the pressing roller bracket 324 through the swing rod 326, the swing rod 326 will swing slightly downward as the pressing roller 322 moves downward. In this way, the pressing roller 322 performs a small arc motion, and the pressing roller cylinder 321 also swings slightly.

[0074] In this embodiment, there are seven groups of pressure roller assemblies 320 within the pressure roller assembly mounting frame 313, each group containing four pressure rollers. The pressure rollers are made of polyurethane. The system controls the movement of pressure roller assemblies 320 at different locations based on the width of the cardboard, pressing the cardboard against the roller conveyor mechanism 3 to prevent slippage and achieve precise conveying distance. Furthermore, the seven groups of pressure roller assemblies 320 can be independently raised and lowered to accommodate cardboard of varying widths.

[0075] The cardboard blocking mechanism 5 is fixed on the side of the pressure wheel assembly fixing frame 313 facing the cardboard conveyor.

[0076] The cardboard blocking mechanism 5 comprises a mounting frame 332, a blocking cylinder 331, and a baffle 335. Two mounting frames 332 are provided, fixed to the inner sides of the left and right ends of the pressure roller assembly mounting frame 313. A blocking cylinder 331 is fixed to each mounting frame 332, and the piston rods of the left and right blocking cylinders 331 are connected to the corresponding ends of the baffle 335. When the blocking cylinders 331 are activated, the piston rods of the blocking cylinders 331 move the baffles 335 up and down, thereby blocking the cardboard on the cardboard conveyor and positioning it in the conveying direction.

[0077] A blocking guide rail 333 is vertically fixed to the inner side surfaces of both ends of the pressure roller assembly fixing frame 313, and a blocking slider 334 is fixed to each mounting frame 332 and is clamped on the corresponding blocking guide rail 333. By providing the blocking guide rail 333 and the blocking slider 334, the up and down movement of the baffle 335 can be guided.

[0078] In this embodiment, the blocking guide rail 333 is a pen-shaped cylinder.

[0079] The pressure roller conveying mechanism 3 includes bearing seats 380 respectively fixed on the two frame legs 110 of the frame 1, a roller 370 arranged between the two bearing seats 380, a third support member 350 fixed on the side of the frame 1, a roller drive motor 310 fixed on the third support member 350, and a belt transmission mechanism for connecting the roller 370 and the roller drive motor 310.

[0080] The belt transmission mechanism includes a driving synchronous wheel 340 fixed on the output shaft of the roller driving motor 310 , a driven synchronous wheel 360 fixed on the corresponding end of the roller 370 , and a synchronous belt 330 provided on the driving synchronous wheel 340 and the driven synchronous wheel 360 .

[0081] When the roller drive motor 310 is activated, it drives the active synchronous pulley 340 to rotate. The active synchronous pulley 340 transmits power to the driven synchronous pulley 360 via the timing belt 330, thereby rotating the roller 370. The roller 370 cooperates with the pressure roller 322 to ensure precise, non-slip, synchronous conveyance of the cardboard after it stops at a fixed position, ensuring accurate positioning of the cardboard at the next workstation, such as a box folding machine. The outer layer of the roller 370 is coated with polyurethane to increase friction.

[0082] The height position of the pressure roller conveying mechanism 3 can be adjusted by adjusting the installation height of the bearing seat fixed on the frame 1 .

[0083] In this embodiment, the third support member 350 is a sheet metal member.

[0084] The motors, cylinders, and other components in the cardboard blocking mechanism 5, cardboard positioning mechanism 2, pressure roller mechanism 4, and pressure roller conveyor mechanism 3 are all controlled by an electrical control system. This electrical control system can be the control system for the entire automated box folding production line or a standalone control system. It consists of electrical components such as power supplies, safety devices, switches, control devices, electrical cabinets, and cables to ensure that the machine operates according to the designed process and rhythm.

[0085] The cylinders in the paperboard blocking mechanism 5, paperboard positioning mechanism 2, pressure roller mechanism 4, and pressure roller conveying mechanism 3 are driven by compressed air supplied by an air source processing and supply system. This system consists of a filter pressure reducing valve, a solenoid valve, auxiliary components (such as adapter air pipes), and mounting supports.

[0086] The operation process of the compact device for servo adjustment and conveyance of paperboard provided by the present invention is as follows:

[0087] When the conveyor detects that there is cardboard placed on it, the conveyor starts and conveys the cardboard. When the photoelectric switch on the conveyor detects that the cardboard has been conveyed to a certain position, the conveyor slows down. At this time, the cardboard blocking mechanism 5 drops down to block the cardboard. At the same time, the photoelectric switch at the end of the conveyor detects whether the cardboard is in place. When it is in place, the conveyor stops working.

[0088] After the conveyor stops working, the cardboard position adjustment mechanism 2 starts to work. Its movable frame transmission mechanism 220 moves the sponge suction cup 235 horizontally to the top of the cardboard. At this time, the sponge suction cup 235 and the suction cup lifting cylinder 231 that controls the up and down movement of the sponge suction cup 235 work simultaneously, sucking up the cardboard, moving it horizontally to the designated position, and then putting it down, completing the positioning of the cardboard in the width direction.

[0089] Then the pressing wheel mechanism 4 is lowered as a whole, and the system controls the movement of the pressing wheel assembly 320 at the corresponding position according to the width of the paper sheet. The pressing wheel cylinder 321 of the pressing wheel assembly 320 drives the pressing wheel 322 to move downward to press the paper sheet against the roller 370.

[0090] Then the roller drive motor 310 of the roller conveying mechanism 3 drives the roller 370 to rotate, and conveys the cardboard forward to the next station. The conveying distance can be precisely controlled.

[0091] After the equipment completes the position adjustment and conveying processes of a piece of cardboard, each mechanism returns to its initial position and waits for the next piece of cardboard.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
