Description

Technical Field

[0001] The utility model relates to the technical field of automated production lines, in particular to a first-in-first-out turntable. Background Art

[0002] In modern automated production lines and material handling systems, the sequential flow and efficient management of workpieces are crucial factors in improving production efficiency and ensuring quality control. This is especially true in production environments where traceability and batch management of each workpiece are crucial. The sequential placement and removal of workpieces is particularly stringent. However, existing technologies often only provide simple material transfer functions, such as placing workpieces or goods on a trolley for transportation. This equipment is limited to material storage and handling, and lacks precise control over the sequential management of materials.

[0003] However, under a production system that involves sequential material processing, existing equipment cannot ensure that materials flow according to the "first-in, first-out" (FIFO) principle. As a result, the order in which workpieces are removed cannot be effectively controlled, thereby affecting overall production efficiency and traceability management of workpiece quality. In particular, in terms of batch management and quality traceability, it is unable to meet strict production requirements. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a first-in-first-out turntable to solve the problems existing in the prior art of chaotic workpiece storage order, inaccurate retrieval order and difficulty in tracing production batches.

[0005] The utility model solves the above technical problems with the following technical solutions: a first-in-first-out turntable, comprising:

[0006] A support frame, wherein a coordinate position A for placing a workpiece and a coordinate position B for taking the workpiece out are marked on both sides of the support frame, and the coordinate position A and the coordinate position B are on the same straight line;

[0007] A carrier assembly for placing multiple workpieces, wherein the carrier assembly includes a turntable, a positioning portion, and a plurality of partitions, wherein the plurality of partitions are distributed in a circular array on the turntable and are used to sequentially separate the multiple workpieces and erect them between coordinate position A and coordinate position B on the turntable. The positioning portion is provided on the partition and is used to limit the erected workpieces. The turntable moves above the support frame;

[0008] A driving member, which is arranged on the top of the support frame and is used to drive the turntable to rotate;

[0009] The sensing part is arranged at the coordinate position B on the support frame. When the workpiece rotates to the coordinate position B, the sensing part stops the rotation of the turntable.

[0010] The beneficial effects of the utility model are:

[0011] 1) This device marks coordinate position A (where the workpiece is placed) and coordinate position B (where the workpiece is taken out) on the support frame, and uses partitions to separate multiple workpieces in sequence and stand them upright on the turntable, ensuring that each workpiece has a clear temporary storage position, and the sensing part is set at coordinate position B. When the driving part drives the turntable to rotate, the workpieces on the turntable will rotate one by one to coordinate position B. When the workpiece reaches position B, the sensing part will automatically stop the rotation of the turntable. At this time, the staff can take out the workpiece at coordinate position B. As the turntable continues to rotate, the next workpiece will rotate to coordinate position B in turn and stop again. Since coordinate position A and coordinate position B are in the same straight line and are set relative to each other, after the turntable rotates, a position will automatically be vacated at coordinate position A. The staff only needs to place the new workpiece at coordinate position A, and so on. The cycle is repeated so that the workpiece always covers half of the turntable to ensure that the workpiece taken out each time is always the earliest workpiece put in, thereby realizing a strict first-in-first-out (FIFO) principle.

[0012] 2) In summary, the order in which workpieces are removed is always effectively controlled, avoiding the common problem of sequence confusion in traditional methods. At the same time, it ensures that the production process and flow path of each workpiece are clearly recorded, facilitating the traceability and quality management of subsequent batches, allowing batches of workpieces to flow in an orderly manner, ensuring that workpieces in the production process will not be confused, and providing reliable support for subsequent quality inspection and management.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the driving component includes a bearing plate and a speed regulating motor, wherein the bearing plate is fixed on the top of the support frame, and the speed regulating motor is fixed on the bottom of the bearing plate, wherein one side output end of the speed regulating motor passes through the bearing plate and is connected to the turntable.

[0015] Furthermore, the support frame is configured as a rectangular frame.

[0016] Furthermore, an abutment structure is provided between the turntable and the support frame.

[0017] Furthermore, the abutment structure includes four rolling members, which are respectively arranged at four corners of the support frame, wherein one rolling member includes a column, an arcuate groove, and a ball, the column is fixed to the top of the support frame, the arcuate groove is opened at the top of the column, and the ball is embedded in the arcuate groove, wherein the radial dimension of the arcuate groove is larger than the radial dimension of the ball, and the radial dimension of the arcuate groove opening on the column is smaller than the radial dimension of the ball.

[0018] The beneficial effects of adopting the above further scheme are as follows: The use of four ball bearings can effectively support the bottom of the turntable, making the turntable structure more stable, ensuring that the turntable will not tilt when temporarily parking workpieces, thus preventing the workpieces from slipping, significantly enhancing the reliability of the turntable, and ensuring the smooth flow and safe storage of materials on the turntable.

[0019] Further, universal wheels are respectively provided at the four corners of the bottom of the support frame.

[0020] Further, the clamping part includes a mounting groove, a U-shaped plate, and an L-shaped clamping block. The mounting groove is opened on one side of the partition board, the U-shaped plate is fixed on the side wall of the mounting groove, and the L-shaped clamping block is fixed on the U-shaped plate.

[0021] The beneficial effects of adopting the above further scheme are as follows: The L-shaped clamping block can effectively clamp the side of the workpiece. During the rotation of the turntable, it can prevent the workpiece from being thrown out due to the action of centrifugal force. Due to the design of the L-shaped clamping block, the workpiece can be firmly restricted on the partition board, ensuring the stability and safety of the workpiece during the entire rotation process.

[0022] Further, the induction part is set as a metal proximity switch. Among them, the metal proximity switch is fixed at the coordinate position B of the support frame, and the metal proximity switch is electrically connected to the speed regulating motor.

[0023] The beneficial effects of adopting the above further scheme are as follows: When a metal workpiece rotates to the coordinate position B, the metal proximity switch can sense the approach of the workpiece and transmit the corresponding electrical signal to the speed regulating motor. After receiving this signal, the speed regulating motor will immediately make an emergency stop response, thereby stopping the rotation of the turntable. Therefore, through the precise induction of the metal proximity switch, when the workpiece reaches the extraction position B, it can timely trigger the speed regulating motor to make an emergency stop, thereby ensuring that the workpiece stays at the correct coordinate position B for the staff to take out.

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] In modern automated production lines and material handling systems, the sequential flow and efficient management of workpieces are crucial factors in improving production efficiency and ensuring quality control. This is especially true in production environments where traceability and batch management of each workpiece are crucial. The sequential placement and removal of workpieces is particularly stringent. However, existing technologies often only provide simple material transfer functions, such as placing workpieces or goods on a trolley for transportation. This equipment is limited to material storage and handling, and lacks precise control over the sequential management of materials.

[0034] However, under a production system that involves sequential processing of materials, existing equipment is unable to ensure the flow of materials according to the "first-in, first-out" (FIFO) principle, resulting in the inability to effectively control the order in which workpieces are removed, thereby affecting the overall production efficiency and the traceability management of workpiece quality, especially in terms of batch management and quality traceability, and unable to meet strict production requirements. In this regard, the utility model proposes a first-in, first-out turntable to solve the above problem.

[0035] The utility model provides the following preferred embodiments

[0036] like Figures 1-6 As shown, a first-in-first-out turntable 210 includes:

[0037] A support frame 10, wherein a coordinate position A101 for placing a workpiece and a coordinate position B102 for taking the workpiece out are marked on both sides of the support frame 10, and the coordinate position A101 and the coordinate position B102 are on the same straight line;

[0038] A carrier assembly 20 for placing multiple workpieces, wherein the carrier assembly 20 includes a turntable 210, a positioning portion 220, and a plurality of partitions 230. The plurality of partitions 230 are distributed in an annular array on the turntable 210 and are used to sequentially separate the multiple workpieces and erect them between coordinate positions A101 and B102 on the turntable 210. The positioning portion 220 is provided on the partitions 230 to limit the erected workpieces. The turntable 210 moves above the support frame 10.

[0039] The driving member 30 is provided on the top of the support frame 10 and is used to drive the turntable 210 to rotate;

[0040] The sensing unit 60 is located at the coordinate position B102 on the support frame 10. When the workpiece rotates to the coordinate position B102, the sensing unit 60 stops the rotation of the turntable 210.

[0041] The device marks the coordinate position A101 (where the workpiece is placed) and the coordinate position B102 (where the workpiece is taken out) on the support frame 10, and uses the partition 230 to separate the multiple workpieces in sequence and stand them upright on the turntable 210, ensuring that each workpiece has a clear temporary storage position, and the sensing part 60 is set at the coordinate position B102. When the driving part 30 drives the turntable 210 to rotate, the workpieces on the turntable 210 will rotate one by one to the coordinate position B102. When the workpiece reaches position B, the sensing part 60 will automatically stop the rotation of the turntable 210. At this time, the staff can move the workpiece located at the coordinate position. The workpiece at coordinate position B102 is taken out. As the turntable 210 continues to rotate, the next workpiece will rotate to coordinate position B102 in sequence and stop again. Since coordinate position A101 and coordinate position B102 are in the same straight line and are arranged opposite to each other, after the turntable 210 rotates, a position at coordinate position A101 will automatically be vacated. The staff only needs to place the new workpiece at coordinate position A101. This cycle is repeated so that the workpieces always cover half of the turntable 210. This ensures that the workpiece taken out each time is always the earliest workpiece put in, thereby achieving a strict first-in-first-out (FIFO) principle.

[0042] In summary, the order in which workpieces are removed is always effectively controlled, avoiding the common problem of sequence confusion in traditional methods. At the same time, it ensures that the production process and flow path of each workpiece are clearly recorded, facilitating the traceability and quality management of subsequent batches, allowing batches of workpieces to flow in an orderly manner, ensuring that workpieces in the production process are not confused, and providing reliable support for subsequent quality inspection and management.

[0043] In this embodiment, Figures 1-6As shown, the driving member 30 includes a carrier plate 310 and a speed-regulating motor 320. The carrier plate 310 is fixed to the top of the support frame 10, and the speed-regulating motor 320 is fixed to the bottom of the carrier plate 310. Among them, one output end of the speed-regulating motor 320 penetrates through the carrier plate 310 and is connected to the turntable 210.

[0044] In this embodiment, as Figures 1-6 shown, the support frame 10 is set as a rectangular frame.

[0045] In this embodiment, as Figures 1-6 shown, a contact structure 40 is provided between the turntable 210 and the support frame 10. The contact structure 40 includes four rolling members, and the four rolling members are respectively arranged at the four corners of the support frame 10. Among them, one rolling member includes a column 401, an arc groove 402, and a ball 403. The column 401 is fixed to the top of the support frame 10, the arc groove 402 is opened at the top of the column 401, and the ball 403 is embedded in the arc groove 402. Among them, the radial dimension of the arc groove 402 is larger than the radial dimension of the ball 403, and the radial dimension of the opening of the arc groove 402 on the column 401 is smaller than the radial dimension of the ball 403;

[0046] The bottom of the turntable 210 can be effectively supported by the four balls 403, making the structure of the turntable 210 more stable, ensuring that the turntable 210 will not tilt when temporarily parking the workpiece, resulting in the workpiece slipping, significantly improving the reliability of the turntable 210, and ensuring the smooth flow and safe storage of materials on the turntable 210.

[0047] In this embodiment, as Figures 1-6 shown, universal wheels 50 are respectively provided at the four corners of the bottom of the support frame 10.

[0048] In this embodiment, as Figures 1-6 shown, the clamping portion 220 includes a mounting groove 221, a U-shaped plate 222, and an L-shaped clamping block 223. The mounting groove 221 is opened on one side of the partition plate 230, the U-shaped plate 222 is fixed to the side wall of the mounting groove 221, and the L-shaped clamping block 223 is fixed to the U-shaped plate 222. The L-shaped clamping block 223 can effectively clamp the side of the workpiece. During the rotation of the turntable 210, it can prevent the workpiece from being thrown out due to the action of centrifugal force. Due to the design of the L-shaped clamping block 223, the workpiece can be firmly restricted on the partition plate 230, ensuring the stability and safety of the workpiece during the entire rotation process.

[0049] In this embodiment, as Figures 1-6As shown, the sensing portion 60 is configured as a metal proximity switch, wherein the metal proximity switch is fixed at the coordinate position B102 of the support frame 10, and the metal proximity switch is electrically connected to the speed regulating motor 320. When the metal workpiece rotates to the coordinate position B102, the metal proximity switch can sense the approach of the workpiece and transmit the corresponding electrical signal to the speed regulating motor 320. After receiving the signal, the speed regulating motor 320 will immediately respond with an emergency stop, thereby stopping the rotation of the turntable 210. Therefore, through the precise sensing of the metal proximity switch, when the workpiece reaches the removal position B, the speed regulating motor 320 can be triggered in time to perform an emergency stop, thereby ensuring that the workpiece stays at the correct coordinate position B102 for the staff to take out.

[0050] The specific working process of this utility model is as follows:

[0051] (1) Place the workpieces in order

[0052] First, the workpieces are placed one by one into the partition 230 along the area between the coordinate position A101 (where the workpieces are placed) and the coordinate position B102 (where the workpieces are taken out) on the turntable 210 .

[0053] (2) Remove the workpieces in order

[0054] Before the speed regulating motor 320 drives the turntable 210 to rotate, a workpiece at the coordinate position B102 can be taken out first. At this time, the speed regulating motor 320 is started and the turntable 210 is driven to rotate by the speed regulating motor 320. At this moment, when the next workpiece is rotated to the coordinate position B102, the metal proximity switch can sense the approach of the workpiece and transmit the corresponding electrical signal to the speed regulating motor 320. After receiving the signal, the speed regulating motor 320 will immediately respond with an emergency stop, thereby stopping the rotation of the turntable 210. Since the coordinate position A101 and the coordinate position B102 are in the same straight line and are arranged relative to each other, after the turntable 210 rotates, a position will be automatically vacated at the coordinate position A101. The staff only needs to place the new workpiece at the coordinate position A101. This cycle is repeated so that the workpieces always cover half of the turntable 210 to ensure that the workpiece taken out each time is always the earliest workpiece put in, thereby realizing a strict first-in-first-out (FIFO) principle.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
