Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and in particular, to an automatic loading rack. Background Art

[0002] With the development of laser technology, laser cutting of profiles has become a reality, enabling the rapid development of profile cutting in automated processing. Laser cutting machines and feeding mechanisms are continuously evolving towards automation, multi-functionality, and large profiles, with products constantly being updated. The automation and wide adaptability of the feeding mechanism are crucial for profile cutting. For the feeding mechanism, Chinese Patent Publication No. CN 114083330 A discloses "Tube Automatic Loading Rack and Its Loading Method". This loading machine realizes the sequential feeding of single tubes through the cooperation of a "feeding channel" and a "clamping mechanism". However, the use of the feeding channel and the clamping mechanism limit the wide applicability of the feeding machine. It has good working efficiency for thin tubes or smaller profiles, but it is difficult to apply to larger profiles or the automated switching of different profiles. Chinese Patent Publication No. CN218908923U discloses "A Unloading Device and a Cutting Machine Using the Same". By adjusting the first adjustment component, the second adjustment component, and the third adjustment component provided on the material rack to synchronously adjust the limiting component, the buffer component, and the supporting component respectively, it can increase the consistency of adjustment to ensure processing accuracy and is also convenient for adjustment. However, it still belongs to semi-automatic adjustment and requires the intervention of workers for adjustment. At the same time, both of the above two solutions use a "blanking chute" and utilize the self-gravity of the profiles for blanking, which will bring a huge impact during the blanking process of the profiles, resulting in noise and vibration. Especially for slightly larger profiles, it is basically inapplicable. Similarly, such as the "Flexible Loading Rack for Tubes" disclosed in Chinese Patent CN219807377U. Chinese Patent Publication No. CN219852665U discloses "Integrated Automatic Pipe Cutting Machine". Through the first lifting mechanism, the belt feeding mechanism, the second lifting mechanism, and the cantilever feeding mechanism, the steel materials are sequentially sent to the position to be processed. The lifting mechanism realizes the handover of each structure through the cooperation of the inclined surface and the groove of the lifting plate, making "the pipe cutting machine divided into various standardized modules, with high transmission accuracy through convenient debugging and installation". However, this standardized module can only set specific pipe fittings and profiles under this standard and does not have universality. Moreover, through lifting - conveying - lifting - conveying, the working efficiency is low, and instability is prone to occur during the lifting - conveying process.

[0003] Therefore, there is an urgent need for an automatic feeding mechanism with high automation, strong adaptability, relatively stable and efficient performance. Summary of the Invention

[0004] In response to the problems of the above-mentioned existing automatic feeding and pipe cutting machines, the present invention provides an automatic feeding rack that can realize fully automatic feeding for most different types of pipes or profiles without manual debugging, with high efficiency and little or no impact on the pipes.

[0005] The purpose of the present invention is achieved through the following technical solutions: An automatic loading rack comprises a base and a storage device and a feeding device arranged on the base, the feeding device comprises a first material platform, the feeding device comprises a lifting mechanism, a second material platform and a unloading mechanism; the second material platform comprises a first end and a second end; a loading slope inclined in the feeding direction is provided between the first material platform and the first end; the lifting mechanism comprises a lifting plate, which is arranged below the first material platform and can move upward to the first end along the loading slope; the unloading mechanism comprises a unloading piece, the upper end of which is higher than the first end and moves between the first end and the second end; the storage device transports the material to the first material platform, the lifting plate lifts the material from the first material platform to the first end, and the material is against the unloading piece; the material moves to the desired position in the direction of the second end under the support of the unloading piece and the unloading slope.

[0006] The present invention can lift materials whose center of gravity is smaller than the width of the lifting plate to the second material platform through the cooperation of the lifting mechanism and the loading ramp, so that the lifting mechanism can lift materials of different sizes without the need for adjustment by operators, and has a wide range of applications. With the cooperation of the lifting mechanism and the unloading piece, materials of different widths can be transported to the second material platform, that is, when the width of the material is narrow, when the lifting plate lifts multiple side-by-side materials, one of the materials can be moved to the second material platform without the need for operators to adjust the equipment. Therefore, through the coordinated cooperation of the lifting mechanism, the loading ramp, the second material platform, and the unloading piece, materials from small width to large width can be moved to the set position without the need for manual adjustment by the equipment operator, and can be done through processing programming. It reduces the debugging of the machinery, reduces the workload of the operators, realizes a larger range of automation, and greatly improves work efficiency.

[0007] Preferably, the lifting plate includes a support top end, the end surface of the support top end is inclined toward one side of the loading slope, and the inclination angle is sufficient to allow the loaded material to slide under its own weight; or the inclination angle of the end surface of the support top end is 20-30°.

[0008] The present invention can increase the stability of the lifting plate in lifting materials by simply setting a slope at the top of the support, and reduces the driving structure for moving the materials on the lifting plate, so the structure is simple and efficient.

[0009] Preferably, the top end of the support protrudes above the feeding slope, and the end face of the top end of the support is substantially perpendicular to the feeding slope and can move along the feeding slope. The fact that the feeding slope and the top end of the support are substantially perpendicular can accommodate materials of different shapes, such as square pipes, round pipes, etc., and avoid large friction. The top end of the support and the feeding slope jointly support the material, such as a round pipe, which can avoid the round pipe from rolling down and reduce the force exerted by the material on the top end of the support.

[0010] Preferably, the first end is higher than the second end, and a discharging slope is formed between the two ends. The inclination angle of the discharging slope is sufficient to enable the fed material to slide under its own weight, and the discharging member moves along the discharging slope. The slope of the discharging slope of the present invention enables the material to move downward under its own gravity without traction or transmission, simplifying the transmission mechanism. There is no need to set a "blanking chute", and the height of the material is not restricted. The discharging mechanism only needs to provide a blocking force for the downward movement of the material. Whether the cross-section of the material is square or circular, etc., the material can be discharged smoothly without impact.

[0011] Preferably, the slopes of the feeding slope and the discharging slope are substantially perpendicular, and sliding rods are respectively arranged on the slopes of the feeding slope and the discharging slope. The sliding rods can reduce friction and make the movement of the material smoother.

[0012] Preferably, the discharging mechanism further includes a material blocking drive, a driving wheel, a driven wheel and a transmission belt. The transmission belt is sleeved between the driving wheel and the driven wheel; a slider is arranged on the discharging member, and a guide rail is arranged on the side wall of the discharging slope. The slider and the guide rail cooperate; the discharging member is fixed on the transmission belt, and the material blocking drive drives the driving wheel to rotate, driving the transmission belt to move. Through the cooperation of the pulley and the guide rail, the material can be conveyed over a long distance, and the structural cost is low. Due to the reasonable design of the slope of the discharging slope, the force on the material transmission belt is not large. Therefore, a belt can be used instead of a transmission structure such as a lead screw.

[0013] Preferably, a material pushing mechanism is included. The material pushing mechanism includes a push plate that moves back and forth. The push plate is arranged between the first end and the first material table. When the push plate extends out of the feeding slope, it can push the material down, and when it retracts into the feeding slope, it does not interfere with the structure. The present invention provides a material pushing mechanism. When the materials are stacked, the upper-layer materials are pushed down to ensure that no matter what kind of storage device the lifting mechanism uses to send the materials to the first material table, only one layer of materials can be sent into the second material table. In the prior art, there is a material pushing mechanism, but it is fixed near the first material table and can only push the materials on the first material table. Therefore, the height of the pushed materials is fixed. However, in the present invention, by combining the material pushing mechanism with the lifting mechanism and the feeding slope, the material pushing mechanism can push the materials out before the second material table. The height of the pushed materials is related to the height lifted by the lifting mechanism, enabling wide adaptation to different materials. Moreover, it can be completed only through processing programming, reducing the manual adjustment procedures of the operators. The automation of material processing is higher.

[0014] Preferably, the push plate is substantially perpendicular to the loading slope and is slidably connected to the side surface of the second material table. The height of the bottom of the push plate from the first material table is greater than the height of the material range to be loaded. The setting of the push plate can be applied to the automatic feeding of materials with different heights.

[0015] Preferably, the pushing mechanism includes a pushing drive. The push plate is fixed to the side wall of the second material table through the cooperation of a guide rail and a slider. The pushing drive is a cylinder to push the push plate to move. The guide rail, the slider and the cylinder make the pushing stable, fast, efficient and more economical.

[0016] Preferably, the lifting mechanism includes a lifting drive provided with a lifting gear; the lifting plate is provided with a lifting rack, a limiting hole and a first slider; the side wall of the first material table is provided with a limiting post and a first guide rail; the first guide rail and the first slider are slidably matched, and the lifting gear and the lifting rack are engaged to drive the lifting plate to move along the first guide rail; the limiting post is inserted into the limiting hole to limit the movement limit of the lifting plate. The cooperation of the gear and the rack can accurately and efficiently send the heavy object to the set position, and the limiting post can limit the position to avoid exceeding the set position.

[0017] Preferably, the storage device includes a support rod fixed on the base, a pulley fixed at the end of the first material table, and a conveyor belt fixed at the top of the support rod and wound around the pulley at the other end and connected to the belt drive. The first material table is provided with an end fillet, and a feeding slope is formed between the end fillet and the base; the belt drive tightens the conveyor belt, and the material is fed into the first material table along the feeding slope. The end fillet and the pulley of the present invention can make the material enter the first material table more smoothly. The width of the first material table can be set according to the maximum width of the feeding, and the end fillet makes corresponding adaptation.

[0018] Preferably, it includes a first sensor and a second sensor, and the first sensor and the second sensor are used to sense whether there is material on the first material table and the second material table respectively. Description of the Drawings

[0026] Embodiment 1: With reference to the accompanying drawings, a kind of automatic feeding mechanism according to an embodiment of the present invention will be described first.

[0027] As Figures 1-3 shown, the automatic feeding mechanism 10 includes a plurality of bases 11. Above each base 11, a storage device 12 and a feeding device 13 are fixed. The feeding device 13 includes a first material table 130 and a second material table 150. Arranging the plurality of bases 11 along the length direction of the profile and at intervals on the same straight line can assemble the loading machine 10. In order to keep each base 11 on the same straight line, fixing connecting rods 111 such as bolts can be detachably fixed between adjacent bases 11. A fixing foot 112 is provided at the bottom of the base 11, and a fixing hole 113 is provided in the fixing foot 112. Expansion bolts, anchor bolts, etc. pass through the fixing hole 113 to fix the fixing foot 112. The storage device 12 sends single or multiple materials, such as round tubes, square tubes, profiles, etc., to the first material table 130. Generally, the first material table 130 only needs to have the width of 1-2 materials, and according to the adaptability requirements, it can be made into 1-2 times the maximum width of the adapted materials.

[0028] The first material platform 130 inclines downward in the direction away from the material storage device 12. Therefore, the material storage device 12 can send one or two materials to the first material platform 130 without falling back.

[0029] A lifting mechanism 140 is arranged on one side of the first material platform 130. The lifting mechanism 140 can move up and down to send the materials delivered to the first material platform 130 to the second material platform 150. The supporting top end 141 of the lifting mechanism 140, and the inclination angle of the supporting top end 141 is substantially equivalent to the inclination angle of the first material platform 130. The said inclination angle is the inclination relative to the horizontal, which can utilize gravity to overcome the frictional force on the surface of the object, so that the materials move downward. Of course, in special cases, when the inclination angle cannot make the materials move downward or the inclination angle is zero, a conveying mechanism such as a conveyor belt or a conveyor chain should be set up.

[0030] As Figures 4-6 As shown, the first end 151 of the second material platform 150 is higher than the first material platform 130. A slope or a rod or the like is provided between the first end 151 and the first material platform 130 as a retaining wall 152. The lower side of the material is lifted by the supporting top end 141 of the lifting mechanism 140, and the side leans against the loading slope 152, and the material can be stably lifted.

[0031] After the lifting mechanism 140 rises to the first position 142 and stays, the pushing mechanism 160 pushes out to push down the stacked materials that may exist on the lifting mechanism 140, so that the lifting mechanism 140 only lifts the materials at the height of one layer, avoiding the superposition of multiple materials and causing overlapping feeding. Specifically, the lifting mechanism 140 rises to the first position 142, and this position can be directly controlled by the system, that is, according to the height of the material, the top end of the material is slightly lower than the height where the pushing mechanism 160 pushes out.

[0032] After the pushing mechanism 160 withdraws, the lifting mechanism 140 rises to the second position 143, and the top surface of the supporting top end 141 is substantially flush with the first end 151, and the material is transferred to the first end 151.

[0033] The second material platform 150 includes a second end 153, and the second end 153 and the first end 151 form a slope, which is a discharging slope 154.

[0034] The blanking mechanism 170 includes a material blocking member 171, and the material blocking member 171 protrudes from the blanking slope 154 and moves along the blanking slope 154. After the material is transferred to the first end 151, the material blocking member 171 moves one position along the blanking slope 154 from the first end 151, so that one piece of material is restricted on the material blocking member 171 and the blanking slope 154. At this time, the lifting mechanism 140 moves downward to the lower side of the first end 151, and then the material blocking member 171 slides down to the second end 153 or a set position near the upper side, completing the automatic delivery of one piece of material to the predetermined position.

[0035] In this embodiment, for the top end 141 of the support, the end face of the top end 141 of the support is inclined towards the feeding slope (152), and the inclination angle is sufficient to cause the fed material to slide under its own weight. Specifically, the inclination angle of the end face of the top end 141 of the support is 20 - 30°, preferably 25°. The end face of the top end 141 of the support protruding from the feeding slope 152 is substantially perpendicular to the feeding slope 152 and can move along the feeding slope 152. The first end 151 is higher than the second end 153, and a blanking slope 154 is formed between the two ends. The inclination angle of the blanking slope 154 is sufficient to cause the fed material to slide under its own weight, and the blanking member 171 moves along the blanking slope 154. Specifically, the inclination angle α between the blanking slope 154 and the top end 141 of the support is 15 - 35°; or the inclination angle α between the blanking slope 154 and the top end 141 of the support is 25 ± 5°, preferably α is 25°. The inclination angle of the feeding slope 152 is 55 - 75°, and the blanking slope 154 is perpendicular to the feeding slope 152.

[0036] The storage device 12 includes a support rod 121, a conveyor belt 122, a pulley 123, and a belt drive 124. The support rod 121 is arranged vertically or inclined upward and is fixedly connected to the base 11. The height of the support rod 12 is higher than that of the first material table 130. One end of the conveyor belt 122 is fixed to the upper end of the support rod 121, and the other end bypasses the pulley 123 and is fixed to the belt drive 124. The pulley 123 is fixed to one side or inside of the first material table 130. The diameter and center of the pulley 123 are basically the same as the end-rounding 131 of the first material table 130, and the material can be smoothly transported to the first material table 130. The belt drive 124 can be a separate motor fixed thereto, or a drive wheel disc connected to the motor rotating rod. The working principle of the storage device is basically the same as that disclosed in Chinese Patent Publication No. CN 114083330 A.

[0037] However, the difference is that the pulley 123 and the belt drive 124 are independently fixed to the feeding device 13. Specifically, the pulley 123 is fixed to one side of the first material table 130, and is basically concentric and of the same diameter as the end-rounding 131 of the first material table 130. The belt drive 124 includes a driving wheel disc 125, a connecting member 126, and a fixing plate 127. The fixing plate 127 is fixed to the feeding device 13 leaving a space for fixing the wheel disc 125. The main shafts on both sides of the driving wheel disc 125 pass through the fixing plate 127 and the feeding device 13 through bearings. The fixing of the bearings includes setting bearing seats, snap rings, etc. Of course, the bearing can also directly be a through hole for receiving and supporting the main shaft. Lubricants, etc. are added to the through hole, and it can also be a standard bearing, which is installed and fixed through a bearing seat. The connecting member 126 is arranged on the outside of the fixing plate, connected to the main shaft 1251 of the driving wheel disc 125 on one side and connected to a transmission shaft, etc. on the other side, and is finally driven by a motor, etc. Of course, the main shaft 1251 passes through the feeding device 13 and is exposed on the other side of the feeding device 13 to the connecting member 126. The connecting member 126 is a connecting member between rods, such as a universal joint, a connector, etc., which can be quickly installed and has stable connection.

[0038] The pulley 123 is also fixed between the fixing plate and the feeding device 13. The fixing plate 127 is triangular in shape, and its three corners are respectively fixed to the feeding device 13 through fasteners such as bolts. The pulley 123 is sleeved on one of the bolts, and on the side between the other two bolts, the driving wheel disc 125 of the belt drive 124 is fixed.

[0039] The feeding device 13 includes a first material table 130 and a second material table 150. The front end surface of the feeding device 13, that is, the other storage device, is an inclined surface. This inclined surface connects the first material table 130 and the base 11. The inclined surface and the support rod form an open mouth, and the material is put in from here. The first end 151 of the second material table 150 is higher than the first material table 130, and a feeding slope 152 is formed between the two; the first end 151 is higher than the second end 153, and a discharging slope 154 is formed between the two. The feeding slope 152 and the discharging slope 154 can be formed by the plate members or rod members of the feeding device 13, or slide rods, etc. can be provided on the feeding device 13 to form the contact parts of the feeding slope 152, the discharging slope 154 and the material sliding. When the slide rod 155 is separately provided, one side of the material abuts against the slide rod 155 and slides along the slide rod 155 under the action of gravity or driving force. Therefore, the resistance is small, the noise is small, and the movement is stable.

[0040] On the feeding device 13, on the other side relative to the pulley 123, a lifting mechanism 140 is fixedly installed.

[0041] Such as Figure 7As shown, the lifting mechanism 140 includes a lifting plate 144 and a lifting drive 145. The top end 141 that supports the material is above the lifting plate 144. The lifting drive 145 is connected to the lifting plate 144 to provide driving force. Specifically, a rack 146 is provided on the side of the lifting plate 144, and the lifting drive 145 is provided with a gear 147. The gear 147 meshes with the rack 146 to drive the lifting plate 144 to move up and down. The rack can be an integral part of the lifting plate 144 or can be detachably connected. A first guide rail 148 is provided on the feeding device 13, and a first slider 149 is provided on the lifting plate 144. The first slider 149 and the first guide rail 148 cooperate to achieve a sliding connection. The lifting plate 144 moves along the first guide rail 148, and the first guide rail 148 is parallel to the loading slope 152. A guiding hole 1441 is provided in the lifting plate 144, and the length of the guiding hole 1441 is parallel to the moving direction of the lifting plate 144. In cooperation with the guiding hole 1441, a guiding column 1442 is fixed on the feeding device 13. The guiding hole 1441 is adapted to the guiding column 1442. The diameter of the guiding column 1442 is slightly smaller than the diameter (width) of the guiding hole 1441, and the length of the guiding hole 1441 is basically the same as the moving range. The guiding column 1442 and the guiding hole 1441 can also be used as movement limits in the moving direction of the lifting plate 144. Preferably, the lifting drive 145 is connected by a transmission rod to achieve single-motor linkage drive. In other embodiments, the lifting drive 145 can be driven by a single motor, or can be driven by a cylinder, a hydraulic cylinder, etc.

[0042] As Figure 4 shown, the pushing mechanism 160 includes a pushing plate 161 and a pushing drive 162. The pushing plate 161 is slidably fixed on the feeding device 13 through a guide rail. The pushing drive 162 pushes the pushing plate 161 to move. The moving direction of the pushing plate 161 is parallel to the unloading slope 154 and is basically perpendicular to the loading slope 152. The pushing drive 162 can be a cylinder or an electromagnetic cylinder, which can be automatically controlled for fast and efficient pushing.

[0043] As Figures 4-5 shown, the unloading mechanism 170 includes a material blocking member 171 and a material blocking drive 172. The material blocking member 171 partially extends out of the unloading slope 154. The material blocking drive 172 drives the material blocking member 171 to move along the inclined surface of the unloading slope 154. The material blocking drive 172 includes a driving wheel 1721, a driven wheel 1722 and a transmission belt 1723. The material blocking member 171 is installed on the transmission belt 1723 through a fixed plate member. The transmission belt 1723 bypasses the driving wheel 1721 and the driven wheel 1722 to form a pulley drive to drive the material blocking member 171 to move. The driving wheel 1721 and the driven wheel 1722 can be belt pulleys, gears or sprockets, and the corresponding transmission belt 1723 can be a belt, a toothed belt or a chain, etc.

[0044] The blanking mechanism 170 sends the material above the feeding and positioning mechanism 20. The feeding and positioning mechanism 20 rises to lift the material, and then the blanking mechanism 170 can return to the first end to repeat the feeding process.

[0045] A first sensor 180 is disposed near the upper side of the first material table 130, and the first sensor 180 is used to detect whether there is material on the first material table 130; a second sensor 190 is disposed near the first end of the second material table 150, and the second sensor 190 detects whether there is material on the second material table 150.

[0046] The automatic feeding mechanism 10 of this embodiment can achieve full-automatic feeding, without the need to manually adjust each structure due to the change of the material shape, and only needs to be controlled in the program. Moreover, during the conveying process of the material, there is no slipping and no collision. The automatic feeding mechanism 10 is hardly impacted, has low noise, and reduces the requirement for the structural strength of the automatic feeding mechanism 10. The structure of this mechanism can be more concise, and it is very convenient for transportation, installation, and changing the site, etc. At the same time, because there is no flipping during the feeding process of the automatic feeding mechanism 10, the material can be non-circular or square, can be triangular, rectangular, etc. When loading the material, there is no need to re-detect the length and width of the material and re-adjust, which provides convenience for the subsequent steps.

[0047] In this embodiment, as Figures 8-11 shown, the feeding steps of the automatic loading rack are as follows: Step 1: Manually place the material and put the material to be processed into the storage device 12 of the automatic loading rack 10. Step 2: Start the automatic loading rack 10 to tighten the conveyor belt 122 and convey the material to the first material table 130 of the feeding device 13. Step 3: The lifting mechanism 140 jacks up the material on the first material table 130, rises to the first position 142 and stops. The push plate 161 is pushed out to a position higher than the required material height on the lifting mechanism 140. After pushing out the object at this place, the push plate 161 returns and does not interfere with the lifting mechanism 140 and the material thereon. Step 4: The lifting mechanism 140 jacks up the first material table 130 from the first position 142 to the second position 143. At the second position 143, the lower end of the material is basically flush with the second material table 150, and the material blocking member 171 blocks one side of the lower end of the material. Step 5: The material blocking member 171 moves obliquely downward along the blanking slope 154. When the material moves along with the material blocking member 171 for a distance equivalent to the set material width, it pauses; the lifting mechanism 140 moves downward, and then the material blocking member 171 moves to the material loading position.

[0048] Step Six: The feeding positioning mechanism 20 rises to lift the material away from the material blocking member 171, and then the material blocking member 171 returns to its original position.

[0049] The present invention and its embodiments are schematically described above. The description is not restrictive. What is shown in the drawings is only one of the embodiments of the method of the present invention, and the actual situation is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
