[0002] In the prior art, when a cutting machine is cutting long strips of profiles, such as aluminum materials used to make window frames, many steps require the participation of workers. For example, workers use a ruler to set the required cutting size; workers need to pick up the long aluminum material and put it on the operating table, and push the aluminum material to the set size by hand; then click a button to start the cutting machine to cut the aluminum material; after cutting, the worker takes the aluminum material away by hand; and after each cutting, the worker needs to push the tail material forward once and operate the equipment for the next cutting. If the size of the entire window frame needs to be cut, the cutting size needs to be adjusted at least twice, and because the entire cutting process requires manual participation, the overall efficiency is relatively low.

[0031] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, the automatic cutting machine of the present invention mainly comprises: a first cutting device 1 and a second cutting device 2 arranged one after the other for cutting out the front and rear ends of the finished profile respectively, a finished product taking device 3 for taking away the cut finished profile, a profile transport device 4 for transporting the profile to be cut to the first cutting device 1 and the second cutting device 2, a profile taking device 5 for taking the profile to be cut onto the profile transport device 4, and a control electrical box with a built-in PLC (Programmable Logic Controller). The first cutting device 1, the second cutting device 2, the finished product taking device 3, the profile transport device 4 and the profile taking device 5 are respectively connected to the control electrical box and controlled by the PLC.

[0033] In this embodiment, the first cutting device 1, the second cutting device 2, the finished product taking device 3 and the profile transport device 4 are each provided with two groups and are respectively arranged on the left and right sides. The profile holding device 5 is provided with two groups and is respectively installed at the front and rear ends of the two groups of profile transport devices 4, thereby forming two groups of cutting machines on the left and right, wherein the front and rear two groups of profile holding devices 5 serve as common devices of the two groups of cutting machines, each group of cutting machines can cut two profiles at the same time, and the two groups of cutting machines cut a total of 4 profiles, such as aluminum strips used to form window frames, which can be assembled into a complete window frame.

[0034] The above-mentioned devices are described in further detail below.

[0035] Figure 2 and Figure 3 The rear and front views of the left and right groups of first cutting devices 1 are shown respectively. Each group of first cutting devices 1 includes: a first cutting blade 11, a first cutting motor 12, a first motor mounting seat 13, a first cutting motor moving device, multiple sensors, and a first dust cover assembly.

[0036] The first cutting blade 11 is mounted on the motor shaft of the first cutting motor 12, and the first cutting blade 11 is driven to rotate by the power output by the first cutting motor 12 to cut the profile. The first cutting motor 12 is mounted on the first motor mounting seat 13, and the first motor mounting seat 13 is also provided with an adjustable mounting plate for adjusting the angle of the first cutting motor 12 and the first cutting blade 11, so as to adjust the angle of the profile cut.

[0037] The first cutting motor moving device is used to drive the first motor mounting seat 13 to move left and right, and includes: a first cutting moving motor 141, a slide rail 142, and a first synchronous belt assembly 143 composed of a synchronous wheel and a synchronous belt. The first motor mounting seat 13 is slidably installed on the slide rail 142, and the synchronous belt in the first synchronous belt assembly 143 is fixedly connected to the first motor mounting seat 13. The first cutting moving motor 141 drives the synchronous belt of the first synchronous belt assembly 143 to move, thereby driving the first motor mounting seat 13 to slide left and right.

[0038] The first dust cover assembly includes a dual-axis cylinder 16 and a dust cover (not shown in the figure). When the profile needs to be cut, the dual-axis cylinder 16 drives the dust cover down to fit the table surface to form a closed space so that the debris generated during the cutting process will not float to other positions of the equipment.

[0039] The above-mentioned multiple sensors are used to sense the position of the first motor mounting seat 13, including: a first positive limit sensor 151, a first origin sensor 152 and a first reverse limit sensor 153. When the first positive limit sensor 151 senses the sensing sheet on the first motor mounting seat 13, the first cutting movement motor 141 will immediately stop so that the first motor mounting seat 13 can no longer move forward and can only move in the opposite direction; when the first reverse limit sensor 153 senses the sensing sheet on the first motor mounting seat 13, the first cutting movement motor 141 will immediately stop so that the first motor mounting seat 13 can no longer move forward and can only move in the opposite direction; each time the automatic cutting machine is restarted or has a new set position, the first motor mounting seat 13 will move to the position fixed by the first origin sensor 152, and when the first origin sensor 152 senses and outputs a signal, the control element in the control box will issue a command to stop the first motor mounting seat 13 and then move it to the set position.

[0040] Figure 4 and Figure 5 The front and rear views of a group of second cutting devices 2 are respectively shown, and each group of second cutting devices 2 includes: a second cutting blade 21, a second cutting motor 22, a second motor mounting bracket 23, a second cutting motor moving device, a profile pressing assembly, a feeding assembly, a cutting platform 24, a platform moving device, multiple sensors, and a second dust cover assembly.

[0041] The second cutting blade 21 is mounted on the motor shaft of the second cutting motor 22, and the second cutting blade 21 is rotated by the power output by the second cutting motor 22 to achieve the cutting of the profile. The second cutting motor 22 is mounted on the second motor mounting seat 23, and the second motor mounting seat 23 is also provided with an adjustable mounting plate for adjusting the angle of the second cutting motor 22 and the second cutting blade 21, so as to adjust the angle of the profile cut.

[0042] The second cutting motor moving device is used to drive the second motor mounting seat 23 to move left and right, and includes: a second cutting moving motor 261, a slide rail 262, and a second synchronous belt assembly 263 composed of a synchronous wheel and a synchronous belt. The second motor mounting seat 23 is slidably installed on the slide rail 262, and the synchronous belt in the second synchronous belt assembly 263 is fixedly connected to the second motor mounting seat 23. The second cutting moving motor 261 is a servo motor, which drives the synchronous wheel of the second synchronous belt assembly 263 to rotate and the synchronous belt to move, thereby driving the second motor mounting seat 23 to slide left and right.

[0043] The feeding assembly is used to convey the profile on the second cutting device 2, and includes: a feeding motor 281, a synchronous belt 282, a synchronous wheel 283 and a feeding roller assembly 284. The feeding roller assembly 284 is composed of a plurality of rollers, a roller bracket, a limiting groove, etc., and its main function is to carry the profile and limit the profile. The feeding motor 281 drives the synchronous wheel 283 to rotate through the synchronous belt 282, and the synchronous wheel 283 drives the roller on the feeding roller assembly 284 to roll.

[0044] The profile pressing assembly is installed on the upper part of the cutting platform 24, and is used to press down the profile and guide and limit the profile. It includes: a front profile pressing assembly 251, a middle profile pressing assembly 252 and a rear profile pressing assembly 253, which are respectively arranged at the front, middle and rear of the cutting platform 24. The front profile pressing assembly 251 and the rear profile pressing assembly 253 are both composed of a double-axis cylinder and a limit guide workpiece. When the profile enters under the two assemblies, the double-axis cylinder drives the limit workpiece to press down, which serves to guide the feed and limit the up and down movement of the profile. The middle profile pressing assembly 252 is provided with two groups, each of which is composed of a double-axis cylinder and a workpiece with a roller. When the profile enters under the assembly, the cylinder drives the roller workpiece to press down, which serves to increase the friction between the profile and the feeding roller assembly 284 when the roller presses down the profile, so that the profile can move forward smoothly and at the same time limit the profile from moving up and down due to the action of force. The purpose of setting two sets of identical components at this position is: since two profiles enter at the same time each time cutting is required, if one of the profiles advances to the right position and the other fails to reach the right position, the double-axis cylinder pressing the profile in place can be raised to reduce the friction of the profile, while the other set of profile pressing components continues to press down, so that the profile that has not reached the right position can continue to advance to the right position.

[0045] The second dust cover assembly includes a dual-axis cylinder 29 and a dust cover (not shown in the figure). When it is necessary to cut the profile, the dual-axis cylinder 29 drives the dust cover down to fit the table surface to form a closed space so that the debris generated during the cutting process will not float to other positions of the equipment.

[0046] The second cutting blade 21, the second cutting motor 22, the second motor mounting seat 23, the second cutting motor moving device, the profile pressing assembly, the feeding assembly and the second dust cover assembly are all installed on the cutting platform 24. The platform moving device is used to drive the cutting platform 24 and the workpieces and components installed on the cutting platform 24 to move forward and backward. The platform moving device includes: a platform moving motor 241, a rack 242 longitudinally arranged along the front-back direction, and two left and right linear guide rails 243. The platform moving motor 241 is a servo motor, which is used to output power to realize the movement of the cutting platform 24. It is installed at the bottom of the cutting platform 24. The gear set on its motor shaft is meshed with the rack 242. The cutting platform 24 is slidably installed on the left and right linear guide rails 243. The rotation of the platform moving motor 241 will drive the cutting platform 24 to slide forward or backward along the linear guide rails 243 through the gear and the rack 242.

[0047] The sensors of the second cutting device 2 include: a second forward limit sensor 271, a second origin sensor 272 and a second reverse limit sensor 273 for sensing the position of the second motor mounting seat 23, a backward limit sensor 274, a third origin sensor 275 and a forward limit sensor 276 for sensing the position of the cutting platform 24, and a feed sensor 277 for sensing whether a profile has reached the feed roller assembly 284.

[0048] When it is necessary to cut the profile, the second cutting moving motor 261 will drive the second cutting motor 22 and its second cutting blade 21 to move to cut the profile. When the second positive limit sensor 271 senses the sensing piece on the second motor mounting seat 23, the second cutting moving motor 261 will stop immediately and cannot move forward, but can only move in the opposite direction. When the profile cutting is completed, the second cutting moving motor 261 will drive the second cutting motor 22 and its second cutting blade 21 to leave the cutting position. When the second reverse limit sensor 273 senses the sensing piece on the second motor mounting seat 23, the second cutting moving motor 261 will stop immediately and cannot move forward, but can only move in the opposite direction. Every time the whole device is turned on, the second cutting moving motor 261 automatically starts to return to the origin. When the corresponding position of the platform where the second cutting motor 22 is installed senses the second origin sensor 272 and outputs a signal, the corresponding electrical components in the control box will issue a command to stop and then start the second cutting moving motor 261, driving the second cutting motor 22 to move to the set position.

[0049] When the platform moving motor 241 drives the cutting platform 24 to move to a position where the backward limit sensor 274 can be sensed, the sensor will send a signal, and the control element in the electrical box will receive the signal and then instruct the platform moving motor 241 to stop immediately. The sensor acts as an emergency stop, and even if there is another backward instruction, the platform moving motor 241 cannot start backward, and can only move in the opposite direction of the direction.

[0050] Each time the cutting machine is restarted or has a new set position, the cutting platform 24 will move to the position of the third origin sensor 275. When the sensor senses and outputs a signal, the control element in the control box will issue a command to stop the cutting platform 24, and then move the cutting platform 24 to the set position.

[0051] When the platform moving motor 241 drives the cutting platform 24 to move to a position where the forward limit sensor can be sensed, the sensor sends a signal, and finally the control element in the electrical box receives the signal and instructs the platform moving motor 241 to stop immediately. The sensor acts as an emergency stop, and even if there is another forward instruction, the platform moving motor cannot start forward and can only move in the opposite direction of the direction.

[0052] Preferably, the installation angles of the first cutting blade 11 and the second cutting blade 21 in the same group are different. The lower part of the first cutting blade 11 corresponds to the placement position of the profile, that is, the lower part is used to cut the profile, and the upper part of the second cutting blade 21 corresponds to the placement position of the profile, that is, the upper part is used to cut the profile. The entire profile of a set length can be cut out at one time, and this design and installation method of the cutting blade can realize the two cutting devices working simultaneously at a close distance without affecting each other, thereby realizing the cutting of shorter profiles.

[0053] Figure 6 What is shown are two groups of left and right finished product taking devices 3, which are installed on the mounting frame 36 and are located above the first cutting device 1 and the second cutting device 2. Each group of finished product taking devices 3 includes: two left and right first guide rails 31 longitudinally arranged in the front-to-back direction, two front and rear mounting plates 32 slidably mounted on the two first guide rails 31, two groups of mounting plate moving devices for respectively driving the two mounting plates 32 to slide back and forth along the first guide rails 31, a first clamping assembly 33 for clamping profiles installed under each mounting plate 32 and capable of vertical movement, and a first rodless cylinder 34 fixed to the bottom of the mounting plate 32 for driving the first clamping assembly 33 to move left and right.

[0054] Each set of mounting plate moving devices further comprises: a driving motor 351 and a third synchronous belt assembly consisting of synchronous wheels 352 and 354 and a synchronous belt 353, wherein the synchronous belt 353 is fixedly connected to the mounting plate 32. When one of the driving motors 351 starts to rotate, it will drive the corresponding synchronous wheels 352 and 354 to rotate and the synchronous belt 353 to move, thereby driving the mounting plate 32 and the first gripper assembly 33 thereunder to move forward or backward.

[0055] Each set of first gripper assembly 33 is composed of a finger cylinder, a double-axis cylinder, a gripper workpiece, a mounting bracket, etc., which can realize the action of clamping or loosening the gripper workpiece or moving it vertically up and down. The front first gripper assembly 33 is used to pick up unqualified cut profiles, while the rear first gripper assembly 33 is used to pick up qualified cut profiles.

[0056] Figure 7 The diagram shows a set of profile holding devices 5 and two sets of left and right auxiliary transport components 41 and material pressing and conveying components 42. Each set of profile holding devices 5 includes: two front and rear second guide rails 52 and a rack 53 disposed transversely on the upper part of a mounting frame 51 along the left and right directions, a slide plate 54 slidably mounted on the second guide rail 52, a transverse moving motor 55 fixed on the slide plate 54, a second gripper assembly 56 mounted below the slide plate 54 for gripping the profile to be cut, and a gripper vertical moving assembly.

[0057] The lateral movement motor 55 is a servo motor, and the gear mounted on the motor shaft of the lateral movement motor 55 meshes with the rack 53. The lateral movement motor 55 drives the gear to rotate, thereby driving the slide plate 54 and the second gripper assembly 56 to move horizontally to the left or right along the second guide rail 52 through the rack 53. The second gripper assembly 56 is composed of a finger cylinder, a gripper workpiece, a mounting frame, etc., and is used to pick up and place profiles. The gripper vertical movement assembly includes a gripper motor 57 and a synchronous belt assembly composed of a synchronous wheel and a synchronous belt, etc., which is used to drive the second gripper assembly 56 to move up and down.

[0058] like Figure 1 and Figure 7 As shown, each group of profile transport devices 4 includes: a plurality of groups of auxiliary transport components 41 arranged longitudinally along the front-to-back direction, and at least two groups of pressing and conveying components 42 arranged in the arrangement direction of the auxiliary transport components 41 .

[0059] like Figure 8 As shown, each group of auxiliary transport components 41 is installed on the top of the mounting frame 43, which includes: a limiting material receiving block 411 for receiving the profile, a double-axis cylinder 412 for driving the limiting material receiving block 411 to rise and fall, a rodless cylinder 413 for driving the limiting material receiving block 411 and the double-axis cylinder 412 to move horizontally left and right, and a receiving roller 414 for supporting and limiting the profile.

[0060] like Fig. 9 As shown, each group of pressing and conveying components 42 is installed on the top of the mounting frame 44, and includes: a load wheel 421, a conveying motor 422 for driving the load wheel 421 to rotate, a fourth synchronous belt component 425, a limiting wheel 423 arranged above the load wheel 421, and a double-axis cylinder 424 for driving the limiting wheel 423 to move up and down. When the profile is placed on the load wheel 421 and the double-axis cylinder 424 drives the limiting wheel 423 to press down, the profile is limited within the set space range, and at this time, starting the conveying motor 422 can realize the conveyance of the profile through the fourth synchronous belt component 425.

[0061] The operation process of the two groups of cutting machines of the automatic cutting machine of the present invention is the same, wherein the front and rear two groups of profile holding devices 5 are common equipment of the two groups of cutting machines, and the difference between the two groups of cutting machines is that the lengths of the profiles cut are different. When the two groups of cutting machines operate at the same time, after the profiles are cut, the four profiles such as aluminum materials cut by the two groups can be assembled into a complete window frame. The following only describes the operation process of one group of cutting machines:

[0062] 1. Set the length of aluminum material to be cut according to production needs;

[0063] 2. Control the cutting platform 24, the first cutting moving motor 141 and the second cutting moving motor 261 to start back to the origin. When the corresponding position of the cutting platform 24 senses the corresponding sensor (the first origin sensor 152, the second origin sensor 272, and the third origin sensor 275) and outputs a signal, the corresponding electrical components in the control box will issue a command to stop the motor and then restart it, driving the corresponding workpiece to move to the set position and finally stop. The set position is the starting position;

[0064] 3. The lateral moving motors 55 in the front and rear profile holding devices 5 are started simultaneously, driving the second gripper assembly 56 to the placement position of the aluminum material;

[0065] 4. After reaching the aluminum material placement position, the gripper motor 57 in the profile device 5 is started, and at the same time, the synchronous belt is driven to rotate so that the gripper in the second gripper assembly 56 moves downward to the set position;

[0066] 5. When the second gripper assembly 56 is lowered into position, the gripper motor 57 stops, and the finger cylinder in the assembly moves to drive the gripper to clamp the aluminum material. When the clamping signal on the finger cylinder is transmitted, the control box sends a command to start the gripper motor 57 again, so that the gripper carrying the aluminum material rises to the set position;

[0067] 6. When the gripper is raised to the position, the lateral moving motors 55 in the front and rear profile holding devices 5 are started simultaneously to move the aluminum material to the set position above the auxiliary transport assembly 41;

[0068] 7. When the profile holding device 5 reaches the set position with the aluminum material, the gripper motor 57 is started to lower the second gripper assembly 56 until the aluminum material is placed on the limiting receiving block 411 of the auxiliary transport assembly 41;

[0069] 8. After the aluminum material is placed stably on the corresponding limiting receiving block 411, the rodless cylinder 413 in the auxiliary transport component 41 is started to deliver the aluminum material to the set position above the receiving roller 414 and the load-bearing wheel 421; when it is in place, the double-axis cylinder 412 in the auxiliary transport component 41 descends to place the aluminum material on the receiving roller 414. After the aluminum material is placed stably on the receiving roller 414, the rodless cylinder 413 is started again to return to its initial position. Then the double-axis cylinder 424 in the pressing and conveying component 42 drives its limiting wheel 423 to press down to place the aluminum material stably;

[0070] 9. When the aluminum material is placed stably on the receiving roller 414 and the limiting wheel 423 of the pressing and conveying assembly 42 presses the aluminum material, the two sets of conveying motors 422 are started to convey the aluminum material to the feeding roller assembly 284 of the second cutting device 2;

[0071] 10. When the aluminum material is transferred to the roller of the feeding roller assembly 284, the feeding sensor 277 senses the aluminum material and outputs a signal to the control box. The electrical control element in the box issues a command according to the signal of the feeding sensor 277 to start the feeding motor 281, driving the roller of the feeding roller assembly 284 to rotate. At this time, the front pressing profile assembly 251, the middle pressing profile assembly 252 and the rear pressing profile assembly 253 are pressed down at the same time. Under the action of the conveying motor 422 and the feeding motor 281, the aluminum material is finally smoothly moved forward in the cutting direction.

[0072] 11. When the aluminum material moves forward to the set position, a corresponding signal is sent to stop the conveying motor 422 and the feeding motor 281;

[0073] 12. When the motor for feeding stops, the double-axis cylinders 16 and 29 in the first dust cover assembly and the second dust cover assembly are started to make the dust cover fit down to the plane of the platform, and then the corresponding first cutting motor 12 and second cutting motor 22 are started at the same time;

[0074] 13. After the above actions are completed, the first cutting moving motor 141 and the second cutting moving motor 261 corresponding to each cutting motor are started to drive the rotating cutting blade to cut the aluminum material in the direction of the aluminum material;

[0075] 14. When the first cutting moving motor 141 and the second cutting moving motor 261 drive the corresponding cutting blades to cut the aluminum material and move to the set position and stop, it means that the cutting is completed; the corresponding electrical components in the control box send out instructions, and the first cutting moving motor 141 and the second cutting moving motor 261 reverse, so that the two cutting motors return to their set starting positions. When reaching the starting position, the first cutting moving motor 141 and the second cutting moving motor 261 and the first cutting motor 12 and the second cutting motor 22 stop at the same time;

[0076] 15. After the aluminum material is cut as required, if the cut aluminum material is qualified, the right-side drive motor 351 starts to rotate, driving the synchronous wheels 352 and 354 and the synchronous belt 353 to rotate, and finally driving the first gripper assembly 33 at the rear to move. When the first gripper assembly 33 reaches the set position above the cut aluminum material, the right-side drive motor 351 stops; the double-axis cylinder in the rear first gripper assembly 33 is actuated to lower the finger cylinder, and finally the gripper picks up the aluminum material. After the aluminum material is picked up, the right-side drive motor 351 starts to drive the aluminum material to move toward the platform where the qualified aluminum material is placed, and puts down the aluminum material after reaching the material placement position. If the aluminum material is unqualified, the left-side drive motor 351 starts to drive the front first gripper assembly 33 related to the motor station to do the same action to take away the unqualified aluminum material, and put the unqualified aluminum material into the waste position;
