Description

Technical Field

[0001] The present application relates to the technical field of hardware sorting, and in particular to an automated sorting system and method for customizing furniture hardware. Background Art

[0002] Customized furniture hardware refers to specific hardware that is selected and designed according to customer needs and the style, material and function of the furniture to ensure that it matches the overall furniture style and function. Customized furniture hardware can provide better quality and design to meet customers' personalized needs and quality requirements for furniture. These hardware include door handles, handles, hinges, slides, locks, etc. With the continuous enrichment of product lines, more and more types of hardware need to be matched. Nowadays, under the trend of automated processing, it has become an industry trend for manufacturers to use automated equipment for product production. Through automated sorting, the production process of customized furniture hardware can be more efficient and accurate, reducing the tediousness and errors of manual operation, and improving production efficiency and quality control.

[0003] For example, in the existing Chinese patent with the publication number CN216174363U, a precision hardware quality inspection device is disclosed, which includes a mounting frame, a detection device is provided on one side of the mounting frame, and collection buckets are provided below both sides of the detection device. A driving assembly is provided inside the mounting frame, and a material discharge assembly is provided on the driving assembly. The material discharge assembly includes a hollow kit and a transmission member fixedly connected to the kit, and the transmission member is provided on the driving assembly. Through the above-mentioned prior art, when the detection device detects the hardware, the detection device sends an electrical signal to the controller, and after receiving the signal, the controller sends a forward or reverse feedback signal to the motor, so that the kit can move back and forth horizontally on the detection device, and the qualified or unqualified hardware can be sorted in the collection buckets on both sides, respectively, realizing the function of automatic material sorting of the equipment.

[0004] However, the above prior art has the following technical defects:

[0005] When the above-mentioned prior art is in operation, the conveyor belt on the mounting frame first brings the hardware to the unloading parts, and then brings the hardware to the gravity sensor through the hose, and the gravity sensor sends an electrical signal to the controller; during the process, the hardware will fall directly onto the gravity sensor each time, and the hardware is usually made of metal materials, which makes it easy to damage the gravity sensor when falling, increasing the detection cost, and also easy to cause wear to the hardware. Secondly, during the sorting process, whether qualified or unqualified hardware will fall directly and accumulate in the collection bucket, so that it is easy to cause scratches and wear on the hardware, which will easily lead to an increase in the defective rate of hardware and cause a decline in quality.

[0006] Based on this, on the basis of the existing precision hardware quality inspection device, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

Then, when the hardware falls on the receiving cloth and falls, the two-way cylinder is started to contract, which can drive the locking gear rod on one of the offset push rods to get stuck on the T-shaped middle block, and then drive the support bracket to rotate to one side, so that the hardware falls on the conveying cloth on one side.

[0026] The hardware that falls onto the conveyor cloth will enter the storage box under the inclined guidance. Since the sponge board is inclined in the storage box through the support plate, the hardware will automatically slide to the corresponding area. As the number of hardware increases, the purpose of layered storage will be gradually achieved in the storage box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-Figure 14 This application is described in further detail.

[0043] The embodiments of the present application disclose an automated sorting system and method for customizing furniture hardware, which can reduce quality inspection costs and avoid damage to equipment during quality inspection and sorting of hardware, and can also prevent wear on hardware during sorting, thereby affecting the production quality of the hardware. Example

[0044] Reference Figure 1 As shown, in the first aspect, the present application provides an automated sorting system for customized furniture hardware, including a conveyor frame 1, a conveyor belt 11 installed on the conveyor frame 1, and guide bars 12 symmetrically arranged on the conveyor frame 1. A quality inspection and sorting device 2 is provided at one end of the conveyor frame 1. Before work, the hardware that needs to be quality inspected and sorted are placed one by one and kept at a certain distance on the conveyor belt 11, and then the conveyor belt 11 is started to rotate to convey the hardware toward the quality inspection and sorting device 2. During the conveying process, the guide bars 12 symmetrically arranged on the conveyor frame 1 can correct and adjust the position of the hardware to avoid deviations in the position of the hardware falling after leaving the conveyor belt 11, thereby affecting the subsequent quality inspection and sorting work.

[0045] Reference Figure 2 and Figure 3 As shown, specifically, the quality inspection and sorting device 2 includes a device table 21 located at one end of the conveying frame 1, and a U-shaped frame 22 is vertically installed in the middle of the device table 21. A convex block 23 and a limiting block 24 are respectively slidably provided on the U-shaped frame 22, and a convex slide 221 and a limiting slide 222 for sliding the convex block 23 and the limiting block 24 are respectively provided on the U-shaped frame 22. A quality inspection mechanism 3 is provided on the U-shaped frame 22 for quality inspection of whether the quality of the hardware is qualified. When the quality of the hardware is qualified, its weight will be maintained within a certain range, and the error range is small; but when the quality of the hardware is unqualified or the necessary parts of the hardware are missing, the weight of the hardware will be greatly different from the weight value of the qualified hardware, and the quality of the hardware can be quickly judged whether it is qualified or unqualified through the corresponding numerical difference.

[0046] The device table 21 is provided with a sorting unit 4 cooperating with the quality inspection mechanism 3 and storage components 5 symmetrically arranged on both sides of the U-shaped frame 22. After the hardware is inspected, the sorting unit 4 can quickly sort qualified and unqualified hardware, automatically allowing qualified hardware to enter the storage component 5 on one side, and unqualified hardware to enter the storage component 5 on the other side.

[0047] Reference Figure 4 and Figure 5As shown, considering that the hardware needs to be inspected first in order to facilitate the subsequent sorting work, the inspection mechanism 3 includes a support frame 31 and a locking unit 6; the support frame 31 is rotatably arranged between the convex block 23 and the limiting block 24 through the middle round rod 32, and one end of the middle round rod 32 extends outward through the limiting block 24. It should be noted that the support frame 31 and the middle round rod 32 are fixedly connected. When the middle round rod 32 is driven to rotate, the support frame 31 rotates together. The limiting block 24 is provided with a middle round hole 241 for the middle round rod 32 to penetrate and install. The support frame 31 is installed with a receiving cloth 33. It should be noted that the surface of the receiving cloth 33 is relatively smooth, and when an object falls on the receiving cloth 33, it will not produce a large concave deformation. The effect achieved is that when the support frame 31 rotates and tilts, it is ensured that the object on the receiving cloth 33 can slide automatically. Two spring rods 34 are respectively arranged in the convex chute 221 and the limiting chute 222 of the U-shaped frame 22, and the telescopic ends of the two spring rods 34 are respectively connected to the lower sides of the convex block 23 and the limiting block 24. Since the maximum stroke of the spring rods 34 is limited, that is, in the initial state without other external forces, the heights of the convex block 23 and the limiting block 24 are always the same, that is, the heights of the support frame 31 and the receiving cloth 33 are always the same. The locking unit 6 is arranged on the limiting block 24 and the middle round rod 32, and is used to keep the support frame 31 balanced and able to cooperate with the sorting unit 4.

[0048] When the hardware is transported by the conveyor belt 11 and falls off the conveyor belt 11, it will fall onto the receiving cloth 33. Under the action of the weight of the hardware, the support bracket 31, the middle round rod 32, the convex block 23 and the limiting block 24 will be driven to move downward, and the two spring rods 34 will shrink; the height to which each qualified hardware moves down and stays is always maintained within a certain range, while unqualified hardware moves down and stays within another height range. The effect of quality inspection of the hardware is achieved by the different heights at which each hardware moves down and stays.

[0049] Reference Figure 6 and Figure 7As shown, since it is necessary to lock the rotation state of the center round rod 32 to keep the support bracket 31 in a horizontal state, and when a hardware falls on the receiving cloth 33, it will not rotate to prevent the hardware from sliding directly. The locking unit 6 includes an assembly bottom rod 61 and a driving member 62; the assembly bottom rod 61 is arranged on the lower side of the limiting block 24 outside the U-shaped frame 22, and a locking rack 64 is provided on the assembly bottom rod 61 through the middle bottom cross block 63 to limit the sliding, and a transverse slide groove 611 for the sliding installation of the middle bottom cross block 63 is provided on the assembly bottom rod 61. Two limit springs 65 are symmetrically arranged in the transverse slide groove 611 of the matching bottom rod 61, and one end of the two limit springs 65 respectively conflicts with the two ends of the middle bottom cross block 63. Driven by the two limit springs 65, the middle bottom cross block 63 is always kept in the middle position of the transverse slide groove 611, that is, the position of the locking rack 64 remains unchanged in the absence of other external forces; the driving member 62 is arranged on the middle round rod 32 and the locking rack 64, and is used to keep the supporting bracket 31 balanced, and can cooperate with the sorting unit 4 to drive the supporting bracket 31 when necessary.

[0050] Continue to refer to Figure 6 As shown, in order to cooperate with the sorting unit 4 to drive the support bracket 31, the driving member 62 includes a driving gear 621 sleeved on the protruding end of the middle round rod 32 and meshed with the locking rack 64, and a T-shaped middle block 622 is provided on one side of the locking rack 64, and a positioning hole 623 is provided on the T-shaped middle block 622. Since the driving gear 621 is always in meshing state with the locking rack 64, the support bracket 31 can be kept in a horizontal state under normal conditions by limiting the middle round rod 32, so as to receive the fallen hardware, and avoid the support bracket 31 from deflecting at an angle, and the hardware directly falls when it falls on the receiving cloth 33.

[0051] Reference Figure 8 As shown, since it is necessary to quickly sort qualified and unqualified hardware after the quality inspection of hardware is completed, the sorting unit 4 includes an outer plate seat 41 and a locking drive member 42; the outer plate seat 41 is arranged on the device table 21, and two L-shaped support rods 43 are symmetrically slidably arranged on the outer plate seat 41, and a number of assembly holes 431 are equidistantly opened on the L-shaped support rod 43, and a two-way cylinder 44 is installed on the outer plate seat 41, and the two telescopic ends of the two-way cylinder 44 are respectively connected to the two L-shaped support rods 43, and the two-way cylinder 44 is started and operated to drive the two L-shaped support rods 43 to slide at the same time. The locking drive member 42 is arranged on the two L-shaped support rods 43, and is used to drive the locking rack 64 to drive the support bracket 31 to rotate.

[0052] Reference Fig. 9As shown, considering the need to cooperate with the driving member 62, before driving the support bracket 31 to rotate, its height position needs to be locked to avoid affecting the normal sliding of the hardware. The locking driving member 42 includes a dislocation lever 422 that is adjustably mounted on the L-shaped support rod 43 through a square inner rod 421, and a locking gear rod 423 is provided at one end of the dislocation lever 422. It should be noted that the tooth spacing on the locking gear rod 423 is adapted to the locking hole 623 on the T-shaped middle block 622.

[0053] Before operation, the heights of the offset push rods 422 on the two L-shaped support rods 43 are adjusted accordingly according to the height ranges where qualified hardware parts move down and stay and the height ranges where unqualified hardware parts move down and stay, so that the position of the offset push rods 422 on one side of the L-shaped support rod 43 is just within the height range where qualified hardware parts move down and stay, and the position of the offset push rods 422 on the other side of the L-shaped support rod 43 is just within the height range where unqualified hardware parts move down and stay.

[0054] When the hardware falls onto the receiving cloth 33 and presses down to drive the convex block 23 and the limiting block 24 to move down and stay at a certain height, the two-way cylinder 44 is started to operate and contract to simultaneously drive the two L-shaped support rods 43 to slide. Since there is a height difference between the offset supporting rods 422 on the two L-shaped support rods 43, only one locking gear rod 423 on the offset supporting rod 422 will conflict with the T-shaped middle block 622, and before the conflict drives the locking rack 64 to slide, the locking gear rod 423 will first be stuck in the locking hole 623 on the T-shaped middle block 622 to lock the height of the support bracket 31 at this time. Then it will conflict and drive the locking rack 64 to slide, thereby driving the middle round rod 32, that is, the supporting bracket 31 to rotate through the driving gear 621. When the locking gear rods 423 on different L-shaped support rods 43 conflict with the T-shaped middle block 622, they will drive the supporting bracket 31 to rotate in different directions, that is, the effect of sorting unqualified and qualified hardware is achieved; the hardware on the receiving cloth 33 automatically slides down and enters the storage component 5 for storage; finally, the two-way cylinder 44 drives the two L-shaped support rods 43 to slide and reset, and the locking gear rod 423 is separated from the T-shaped middle block 622. At this time, under the action of the two limit springs 65, the locking rack 64 is reset and then drives the supporting bracket 31 to rotate in a parallel state. At this time, due to the lack of the weight of the hardware, the two spring rods 34 will push the supporting bracket 31 upward to return to the initial height.

[0055] Reference Fig.10As shown, in order to prevent hardware from falling directly during storage, a large number of hardware are piled up at the same position. The storage assembly 5 includes a conveying cloth 51 and a storage component 7; the two conveying cloths 51 are respectively arranged obliquely and symmetrically on both sides of the U-shaped frame 22 through two round support rods 52, and a rectangular outlet 211 for the conveying cloth 51 to extend and install is symmetrically opened on the device table 21. Both sides of the device table 21 are symmetrically provided with L-shaped lifting rods 53 for fixing one end of the round support rod 52. When the hardware is separated from the receiving cloth 33 and slides downward, it will fall onto the conveying cloth 51. Through the inclined setting of the conveying cloth 51, the hardware can slide downward through the rectangular outlet 211 by itself. The receiving cloth 33 and the conveying cloth 51 are used to prevent the hardware from being damaged during the transfer process. The storage component 7 is symmetrically arranged on both sides of the device table 21, and is used to store the hardware that slides out through the rectangular outlet 211.

[0056] Reference Fig.10 and Fig.11 As shown, it is a schematic diagram of the structure of the storage component 7 in this embodiment. The storage component 7 includes a storage box 71 symmetrically arranged on both sides of the device table 21 and located below the rectangular outlet 211. In this embodiment, preferably, three sponge boards 73 are obliquely arranged in the storage box 71 through a supporting plate 72, and the inclination direction of each layer of sponge board 73 is different; a storage baffle 74 is limitedly slidably installed on one side of the storage box 71, and a discharge port 711 for installing the storage baffle 74 is opened on the storage box 71.

[0057] After the hardware enters the storage box 71, it will first be received by the top sponge board 73, and under the tilting effect, the hardware will automatically slide to the next sponge board 73 until it slides to the bottom. As the number of hardware increases, each layer of sponge board 73 will be gradually filled up, so that the hardware is stored in layers in the storage box 71 to prevent wear caused by excessive accumulation. When the stored hardware needs to be taken out, the storage baffle 74 is pulled out upwards to take out the hardware through the discharge port 711. Example

[0058] Reference Fig.12 and Fig.13As shown, on the basis of the first embodiment, in order to enable the hardware to be stored more evenly and prevent a large number of hardware from being excessively piled together and causing wear, a uniform placement component 8 is further provided on the device table 21. The uniform placement component 8 includes an inner block 81 installed on one side of the storage box 71 so that the storage box 71 is limitedly slidable on one side of the device table 21. The device table 21 is symmetrically provided with rectangular slide grooves 212 for the inner block 81 to be installed. The rectangular slide groove 212 of the device table 21 is covered with a limited block 82. The rectangular slide groove 212 of the device table 21 is in the device table 21. A bidirectional screw rod 83 is provided for rotation, and one end of the bidirectional screw rod 83 is threadedly penetrated through the inner block 81 and penetrates the limit block 82 to extend outward, the inner block 81 is threadedly penetrated to open an internal threaded hole 811 adapted to the bidirectional screw rod 83, and the limit block 82 is penetrated to open a round rod hole 821 for the bidirectional screw rod 83 to penetrate and extend out; when the bidirectional screw rod 83 is subjected to force and rotates, the internal threaded hole 811 opened on the inner block 81 can drive the inner block 81 to slide back and forth in the rectangular slide groove 212, that is, drive the storage box 71 to move back and forth.

[0059] The two bidirectional screw rods 83 are sleeved with double-groove transmission wheels 84 at their extended ends, and a driving motor 86 is provided on the device platform 21 through a motor seat 85. A double-groove driving wheel 87 is sleeved on the rotating shaft of the driving motor 86, and a driving belt 88 is sleeved on the double-groove driving wheel 87 and the double-groove transmission wheel 84. The driving motor 86 is started to operate to synchronously drive the two bidirectional screw rods 83 to rotate, so that the two storage boxes 71 remain in a moving state, and then when the hardware enters the storage box 71, it will not always be piled up in the same position, so that the hardware can be stored in a dispersed manner.

[0060] Reference Fig.14 As shown, on the other hand, the present application also discloses an automated sorting method for customized furniture hardware, and the steps of the sorting method are as follows:

[0061] The first step is rapid quality inspection: the hardware that needs to be inspected and sorted is transported in sequence toward the device table 21 through the conveyor belt 11 on the conveyor frame 1, and the hardware is accurately placed into the quality inspection mechanism 3 under the limiting guidance of the guide bar 12; under the transport of the conveyor belt 11, when the hardware falls off the conveyor belt 11, it will fall onto the receiving cloth 33, so as to drive the support frame 31, the middle round rod 32, the convex block 23 and the limiting block 24 to move downward, and the effect of quality inspection of the hardware is achieved by the different heights of each hardware when it moves downward.

[0062] The second step is position locking: qualified and unqualified hardware entering the quality inspection mechanism 3 will be lowered to different heights. Under the operation of the sorting unit 4, the position height of the hardware will be locked first to facilitate the subsequent sorting work; when the hardware moves down and stays at a certain height, the two-way cylinder 44 is started to drive the locking gear rod 423 on the misaligned support rod 422 to conflict with the T-shaped middle block 622, and the locking gear rod 423 will first be stuck in the positioning hole 623 on the T-shaped middle block 622 to lock the height of the support bracket 31 at this time.

[0063] The third step is fast sorting: as the sorting unit 4 continues to operate, qualified and unqualified hardware are transferred to the storage components 5 symmetrically arranged on both sides of the U-shaped frame 22; the locking gear rod 423 contacts and drives the locking rack 64 to slide, so as to drive the support bracket 31 to rotate. When the locking gear rods 423 on different L-shaped support rods 43 contact the T-shaped middle block 622, they will drive the support bracket 31 to rotate in different directions, that is, to achieve the effect of sorting qualified and unqualified hardware.

[0064] Step 4: Layered storage: The storage component 5 will store the hardware that has passed the quality inspection in layers to prevent excessive accumulation of a large number of hardware. After entering the storage box 71, the hardware will first be received by the sponge board 73 on the top layer, and under the tilting effect, the hardware will automatically slide to the next layer of sponge board 73 until it slides to the bottom. As the number of hardware increases, each layer of sponge board 73 will be gradually filled up to achieve the purpose of layered storage. The operation of the drive motor 86 can keep the two storage boxes 71 in a moving state, and then when the hardware enters the storage box 71, it will not always accumulate in the same position, so that the hardware can be stored in a dispersed manner.
