Description

Technical Field

[0001] The present invention relates to the technical field of profile storage, in particular to a temporary storage device for door and window profile materials. Background Art

[0002] Door and window profiles are essential materials in the construction industry and are widely used in the manufacture of various types of doors and windows. To improve production efficiency, temporary storage of door and window profiles is often necessary in door and window processing and conveying lines, ensuring ready access during processing. Temporary storage not only ensures continuous production line operation but also reduces material loss during transportation, improving overall production efficiency. Therefore, designing an efficient and practical temporary storage device for door and window profiles is crucial.

[0003] In the processing and conveying production line of doors and windows, temporary storage of door and window profile materials is particularly important to improve production efficiency. As a key component in this process, the design of the temporary storage box directly affects the efficiency of material storage, conveying, and retrieval. However, traditional temporary storage box designs have many shortcomings.

[0004] Traditional temporary storage boxes often simply provide a space for storing materials and lack automated material conveying and temporary storage mechanisms. When materials are transported to the vicinity of the temporary storage box via a conveyor belt, workers need to manually remove the materials from the conveyor belt and place them in the temporary storage box. This method not only increases labor costs but also requires workers to constantly monitor material transportation, reducing work efficiency. In addition, traditional temporary storage boxes lack flexibility during the material storage process. Once materials are placed in the box, they are difficult to move or rearrange. This results in the need to spend more time and effort to arrange or retrieve the required materials when retrieving them later.

[0005] For this reason, we propose a temporary storage device for door and window profile materials. Summary of the Invention

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] See also Figure 1-15 , the embodiment of the present invention provides a technical solution: a temporary storage device for door and window profile materials, including a bracket 1 and a temporary storage box 2, the bracket 1 is provided with a feed roller group 3 for conveying door and window profile materials, the temporary storage box 2 is provided with a first-level temporary storage roller group 5, the feed roller group 3 is close to the first-level temporary storage roller group 5. The side is set as the discharge end, and the other end is the feed end, and the gap between the feed roller group 3 and the first-level temporary storage roller group 5 near the discharge end is passed through a lifting device 72 to install a lifting conveyor belt 7, and multiple groups of overlapping racks 71 for overlapping door and window profile materials are fixedly provided on the temporary storage box 2. The door and window profile materials can be put into the storage box 2 through the feed roller group 3. The material is transported from the feed end to the discharge end. When the material is delivered to the discharge end, the lifting conveyor belt 7 is driven by the lifting device 72 to rise upward, and the material at the discharge end of the feed roller group 3 is lifted. Then, under the drive of the lifting conveyor belt 7, the material is moved sideways to the overlapping frame 71. In order to ensure that the lifting conveyor belt 7 can be raised in time after the material enters the discharge end of the feed roller group 3, a photoelectric or gravity sensor can be set on the bracket 1 to control the start and stop of the lifting device 72. The photoelectric or gravity sensors used are all existing technologies and will not be described in detail here. The door and window profile material temporary storage device also includes:

[0046] The conveying drive mechanism provided on the feed roller group 3 and the lifting mechanism provided between the temporary storage box 2 and the first-level temporary storage roller group 5 and connected to the conveying drive mechanism, when the material is continuously moved to the overlapping rack 71 by the lifting conveyor belt 7, the conveying drive mechanism drives the lifting mechanism to gradually raise the first-level temporary storage roller group 5. Whenever a material is conveyed through the feed roller group 3, the conveying drive mechanism will raise the first-level temporary storage roller group 5 once through the lifting mechanism, that is, the material is conveyed through the feed roller group 3 and pushed to the overlapping rack 71 by the lifting conveyor belt 7. When the first temporary storage roller group 5 is raised, the first temporary storage roller group 5 rises until multiple profile materials are placed on the overlapping rack 71. At this time, the first temporary storage roller group 5 is lifted by multiple groups to realize the lifting action of multiple groups of materials on the overlapping rack 71. The temporary storage box 2 is also provided with a secondary temporary storage roller group 51. After the multiple groups of materials are lifted by the first temporary storage roller group 5, the multiple groups of materials are conveyed to the secondary temporary storage roller group 51; after the multiple groups of materials are lifted by the first temporary storage roller group 5, the height of the materials is the same as the height of the secondary temporary storage rollers. At this time, the materials are conveyed to the secondary temporary storage rollers by the first temporary storage roller group 5;

[0047] The passive drive roller 52 provided in the temporary storage box 2 is rotated. A transmission mechanism is provided between the passive drive roller 52 and the first-level temporary storage roller group 5. When the first-level temporary storage roller group 5 lifts the material on the overlapping rack 71, the passive drive roller 52 is rotated through the transmission mechanism.

[0048] The quick-drop mechanism is provided between the passive drive roller 52 and the lifting mechanism. When multiple groups of materials are conveyed from the primary temporary storage roller group 5 to the secondary temporary storage roller group, the quick-drop mechanism is used to quickly drop the primary temporary storage roller group 5 back to its initial position. After the first-level temporary storage roller group 5 conveys the material to the second-level temporary storage roller group 51, the quick-descent mechanism causes the first-level temporary storage roller group 5 to quickly return to its initial position instead of sinking step by step, so as to prevent the first-level temporary storage roller group 5 from limiting the profile material when the lifting conveyor belt 7 moves the next profile material sideways. In this way, the material is continuously moved along the first-level temporary storage roller group 5 to the second-level temporary storage roller group 51. There is no need to remove the material every time it is moved sideways to the first-level temporary storage roller group 5. Instead, after a certain amount of material is accumulated, multiple groups of materials are sent to the second-level temporary storage roller group together. At this time, multiple groups of materials are processed together, which improves efficiency. In this way, multiple groups of materials conveyed to the overlapping rack 71 are arranged side by side and then conveyed to the second-level temporary storage roller group 51 together. The profile materials can be automatically arranged, which is convenient for staff to process and has good practicality.

[0049] The support frame 71 is provided with an L-shaped support structure, and the support frame 71 is provided with an L-shaped support structure. The lifting mechanism 71 is a kind of L-shaped structure, which is suitable for the lifting and lowering of the load-bearing frame 71 and the lifting and lowering of the load-bearing frame 72.

[0050] Among them, the transmission drive mechanism includes a conveyor belt 1 4 and a conveyor belt 2 43, and the surfaces of the conveyor belt 1 4 and the conveyor belt 2 43 are respectively provided with a push rod 41 and a resistance rod 42, the conveyor belt 1 4 and the conveyor belt 2 43 are arranged along the direction from the feed end to the discharge end of the conveying roller group, and the conveyor belt 1 4 and the conveyor belt 2 43 are respectively installed on different rollers of the feed roller group 3 through synchronous wheels, wherein the roller of the feed roller group 3 on which the conveyor belt 2 43 is installed is an unpowered roller. When the material is conveyed through the feed roller group 3, the conveyor belt 1 4 is in the The feed roller group 3 rotates autonomously under the drive, and the push rod 41 thereon also rotates back and forth with the conveyor belt 1 4. At this time, when the profile material is conveyed to the conveyor belt 1 4, the material is conveyed to the conveyor belt 2 43 through the conveyor belt 1 4. At this time, the material contacts the resistance rod 42, and then the push rod 41 pushes the material, causing the conveyor belt 2 43 to rotate via the resistance rod 42; the roller on the feed roller group 3 on which the conveyor belt 2 43 is installed is connected to the lifting mechanism through a connecting part, and the connecting part is used to transmit power in one direction. By setting the conveyor belt and the second conveyor belt 43, the second conveyor belt 43 will rotate only when there is material being conveyed on the feed roller group 3, thereby transmitting power to the lifting mechanism through the connection part, so that the lifting mechanism will only make the first-level temporary storage roller group 5 rise once when there is material passing through the second conveyor belt 43. Each time there is material passing through the second conveyor belt 43, the first-level temporary storage roller group 5 will rise once until the first-level temporary storage roller group 5 lifts the multiple groups of materials on the overlapping frame 71 and conveys them to the second-level temporary storage roller group 51. The two cooperate with each other to realize the temporary storage of materials and the conveyance of the temporarily stored materials to the second-level temporary storage roller group 51.

[0051] In one embodiment of the present invention, the lifting mechanism includes multiple groups of slotted plates 95 fixedly arranged on the first-level feed roller group 3, and multiple groups of drive discs 9 and half gears 91 corresponding to the number of slotted plates 95, and the multiple groups of drive discs 9 and half gears 91 are all rotatably arranged on the temporary storage box 2, one of the half gears 91 is connected to the connecting part, when the material is pushed to the surface of the conveyor belt 2 43 and the conveyor belt 2 43 is rotated by the push rod 41, one of the half gears 91 is rotated by the transmission part, and the outer surface of the drive disc 9 is provided with a meshing tooth 91 that meshes with the half gear 91. 2. A slider 99 is installed at the eccentric position of the drive plate 9 through a crank 93, which is slidably arranged in a limiting track 94. When the half gear 91 rotates, the drive plate 9 rotates through the meshing tooth 92, thereby causing the crank 93 to slide and cause the slider 99 to reciprocate up and down in the limiting track 94. The slider 99 is provided with a lifting rod 96 through the rotation of a torsion spring, and the end of the lifting rod 96 is provided with a push block 97 that abuts against the notch surface of the slotted plate 95 through the rotation of the torsion spring. A limiting block 98 is fixedly provided at the position of the lifting rod 96 near the push block 97, which abuts against the bottom surface of the push block 97. Please refer to Figure 6 and Figure 7When the slider 99 reciprocates up and down in the limiting track 94, the lifting rod 96 drives the push block 97 to reciprocate up and down. When the lifting rod 96 moves downward, the push block 97 forms friction with the surface of the slotted plate 95, and the push block 97 deflects upward until the lifting rod 96 drives the push block 97 to start moving upward. At this time, the push block 97 returns to its original position under the action of the torsion spring and contacts the notch surface of the slotted plate 95 upward, thereby pushing the slotted plate 95 upward to push the first-level temporary storage roller group 5 upward. Each group of half gears 91 is connected by a linkage mechanism. Through the linkage mechanism, each half gear 91 rotates synchronously, and the teeth on the two half gears 91 in the diagonal direction are in the same direction, and the teeth of the two half gears 91 perpendicular to the material conveying direction are in opposite directions, and the teeth of each half gear 91 are all facing up and down.

[0052] The material is then transported to the feed roller assembly 3 behind the conveyor belt 2 43 , and the material is then transported to the feed roller assembly 3 behind the conveyor belt 2 43 . The plurality of half gears 91 rotate half a circle at the same time, and one part of the half gears 91 meshes with the meshing tooth 1 92 when rotating half a circle, so that the driving disc 9 of this part rotates, while the half gears 91 of the other part rotate half a circle, which is equivalent to idling, and does not cause the driving disc 9 to rotate. That is to say, when the material passes through the conveyor belt 2 43 and causes the conveyor belt 2 43 to rotate, the driving disc 9 at the diagonal position can be rotated or not rotated through the connection part and the linkage mechanism, and the rotating driving disc 9 will push the slotted plate 95 upward after performing an up and down reciprocating motion through the push block 97, so that the first-level storage roller group rises, and the push block 97 on the other non-rotating driving disc 9 at the diagonal position supports the slotted plate 95 when the other push block 97 reciprocates up and down and pushes the slotted plate 95 upward, so as to prevent all the push blocks 97 from performing an up and down reciprocating motion with the lifting rod 96, resulting in the slotted plate 95 and the first-level temporary storage roller group being unable to rise.

[0053] It should also be noted that when the drive disc 9 rotates one circle, the distance that the push block 97 reciprocates up and down is slightly larger than the spacing between the slots of the slotted plate 95. In other words, when the drive disc 9 rotates one circle, the distance that the push block 97 pushes the slotted plate 95 and the first-stage temporary storage roller group 5 to move upward is the spacing between the slots of the slotted plate 95.

[0054] In one embodiment of the present invention, the linkage mechanism includes a linkage rod 10 and a synchronous belt 3 101. The linkage rod 10 is fixedly arranged between two half gears 91 perpendicular to the material conveying direction, and the synchronous belt 3 101 is installed on the linkage rod 10 through a synchronous wheel. When one of the half gears 91 connected to the connecting portion rotates, the synchronous belt 3 101 and the linkage rod 10 can achieve synchronous rotation of multiple half gears 91.

[0055] In one embodiment of the present invention, the rapid descent mechanism includes a rack 114 slidably arranged on a slide rail 113 and a meshing tooth 112 arranged on the surface of the passive drive roller 52 and meshing with the rack 114. The slide rail 113 is arranged on the temporary storage box 2, and the inner wall surface of the slide rail 113 is connected to the surface of the rack 114 through a return spring 116. An extrusion portion is provided on the rack 114 through a driving block 115. When the passive drive roller 52 rotates, the lifting rod 96 is deflected and disengaged from the slotted plate 95 through the extrusion portion, thereby realizing the rapid return of the first-level temporary storage roller group 5 under the action of gravity. When the first-level temporary storage roller group 5 moves upward to lift the material, the passive driving roller 52 is rotated by the transmission mechanism, so that the rack 2 114 slides in the slide rail 113 through the meshing gear 2 112, and the return spring 116 is deformed at the same time. At this time, the extrusion part is driven by the driving block 115 to deflect the multiple lifting rods 96 and simultaneously separate the multiple push blocks 97 from the slotted plate 95. At this time, under the action of gravity, the slotted plate 95 and the first-level temporary storage roller group 5 fall back to the initial position to prevent the next material from interfering when being transported sideways by the lifting conveyor belt 7. This rapid return function ensures the continuity and efficiency of the device, avoids the material accumulation and transportation problem caused by the first-level temporary storage roller group failing to return to its original position in time, thereby further improving the overall performance of the temporary storage box 2 when temporarily storing profile materials. In order to prevent the first-level temporary storage roller group 5 from falling back under the action of gravity and causing damage, a soft pad is provided between the first-level temporary storage roller group 5 and the direct second;

[0056] In another embodiment of the present invention, the extrusion portion includes a clamping plate 111 and a rotating rod 11. The rotating rod 11 is rotatably disposed at the end of the lifting rod 96. One end of the clamping plate 111 is fixed to the driving block 115, and the other end abuts against the outer peripheral side of the rotating rod 11. Figure 6 、 Figure 11 and Figure 12The clamping plate 111 is provided with an arc at a position close to the rotating rod 11. When the passive driving roller 52 rotates and drives the driving block 115 through the rack 2 114 to move the clamping plate 111 toward the direction close to the rotating rod 11, the arc set on the clamping plate 111 can apply outward pressure to the rotating rod 11, thereby causing the lifting rod 96 to deflect and the push block 97 to separate from the slotted plate 95.

[0057] In order to make the movement of the clamping plate 111 more stable over a long distance, a limiting groove 117 is fixedly provided on the temporary storage box 2, and the clamping plate 111 slides in the limiting groove 117;

[0058] Among them, the transmission mechanism includes mutually meshing bevel gear disc 1 81 and bevel gear disc 2 82 and mutually meshing bevel gear disc 3 85 and bevel gear disc 4 86, wherein bevel gear disc 1 81 and bevel gear disc 2 82 are rotatably set on the first-level temporary storage roller group 5, and bevel gear disc 1 81 is connected to one of the rollers of the first-level temporary storage roller group 5, bevel gear disc 3 85 and bevel gear disc 4 86 are rotatably set on the second-level temporary storage roller group 51, and bevel gear disc 4 86 is connected to the passive drive roller 52, and a connecting shaft 83 is provided on the bevel gear disc 2 82, and the transmission mechanism also includes a driving member 1 87 and a driving member 2 88, wherein the driving member 2 88 is provided on the bevel gear disc 3 85, and a synchronous belt 2 84 is installed between the driving member 1 87 and the connecting shaft 83 through a synchronous wheel. When the first-stage temporary storage roller group 5 rises, the bevel gear disc 1 81 and the bevel gear disc 2 82 also rise continuously. Since the first-stage temporary storage roller group 5 is continuously in a working state, the rollers thereon continue to rotate. In this way, when the first-stage temporary storage roller group 5 lifts the material and the driving member 1 87 and the driving member 2 88 collide with each other, the power of the first-stage temporary storage roller group 5 will be transmitted to the passive drive roller 52, thereby causing the passive drive roller 52 to rotate.

[0059] In order to enable the second driving member 88 to rise more stably when the first-level temporary storage roller group 5 rises, a connecting frame 8 is fixedly provided between the second synchronous belt 84 and the first-level temporary storage roller group 5;

[0060] In one embodiment of the present invention, the first and second connectors may be friction discs, through which the power is transmitted, or they may be end face gears that cooperate with each other. Both are existing products and will not be described in detail here.

[0061] It should also be noted that when the curvature of the clamping plate 111 squeezes the rotating rod 11 and deflects the lifting rod 96, the center of gravity of the profile material is on the secondary temporary storage roller group 51. In this way, when the primary temporary storage roller group 5 falls back under the action of gravity, the profile material will not fall. Moreover, when the primary temporary storage roller group 5 falls back under the action of gravity, the mutually conflicting connecting member 1 and connecting member 2 will also separate, and the reset spring 116 will restore its deformation, pulling the clamping plate 111 back to its original position. As a result, under the action of the torsion spring, the lifting rod 96 is restored, thereby carrying out the subsequent lifting operation of the primary temporary storage roller group 5.

[0062] The door and window profile material temporary storage device also includes a restoration mechanism. After the material passes through the second conveyor belt 43 and the interference rod 42 is separated from the material, the restoration mechanism is used to restore the second conveyor belt 43 and the interference rod 42 on the second conveyor belt to their original positions.

[0063] In one embodiment of the present invention, the recovery mechanism includes a lifting frame 6 arranged on the lifting conveyor belt 7 and a rack 1 61 fixed on the lifting frame 6, a gear 1 62 and a ratchet 2 64 are rotatably arranged on the bracket 1, and a claw 2 63 is arranged at the end of the gear 1 62 extending into the cavity of the ratchet 2 64, and the ratchet 2 64 is connected to the roller on the feed roller group 3 on which the conveyor belt 2 is installed. When the material passes through the conveyor belt 2 43, the interference rod 42 rotates together with the conveyor belt 2 43, and when the lifting conveyor belt 7 rises to shift the material sideways, the rack 1 61 engages with the gear 1 62, but due to the structure of the ratchet 2 64 and the claw 2 63, the ratchet 2 64 and the claw 2 63 produce a knocking phenomenon, and the conveyor belt 2 43 cannot rotate. After the lifting conveyor belt 7 completes the side shifting of the material, when the lifting conveyor belt 7 descends, the rack 1 61 drives the gear 1 62 to rotate, thereby causing the conveyor belt 2 43 to rotate until the interference rod 42 on the conveyor belt 2 43 returns to its original position.

[0064] In one embodiment of the present invention, the connection portion includes a ratchet 45 and a pawl 46. The outer periphery of pawl 46 and the outer periphery of one of the half gears 91 are connected to a synchronous belt 44 via a synchronous wheel. Ratchet 45 is rotatably mounted on bracket 1 and connected to one of the rollers of feed roller assembly 3, on which conveyor belt 2 is mounted. Pawl 46 is rotatably mounted on bracket 1 on the side away from synchronous belt 44 and abuts against a groove in ratchet 45. When conveyor belt 2 43 and its contact rod 42 are restored to their original positions by the restoration mechanism, a toothing phenomenon occurs between pawl 46 and ratchet 45. In other words, the lifting mechanism will only lift the primary temporary storage roller assembly 5 via the connection portion when material is being fed onto conveyor belt 2 43. Restoring the contact rod 42 does not cause any changes in the lifting mechanism.

[0065] It should also be noted that the height of the passive drive roller 52 is lower than that of the secondary temporary storage roller set 51. When the material is conveyed by the secondary temporary storage roller set 51, the material does not come into contact with the passive drive roller 52, thereby preventing excessive friction between multiple groups of material and the passive drive roller 52, which could cause the return spring 116 to be unable to rebound.

[0066] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
