Description
Technical Field
[0001] This utility model relates to the field of roll material measurement technology, and specifically to a roll material size measuring device. Background Technology
[0002] Before new materials arrive or leftover rolls are put back into storage on processing machines, their dimensions must be checked. This is to determine the appropriate storage location and to facilitate the retrieval of suitable rolls for subsequent processing.
[0003] During the warehousing process of iron core coils, it is necessary to inspect the diameter and width of the coils. Currently, the common method is to manually lift the coils from their horizontal position using an overhead crane, measure the data manually with a measuring tape, and then manually record it into the system. Therefore, existing technology suffers from the problem of errors easily introduced by manually measuring data with a measuring tape.
[0004] Based on the above technical issues, in order to quickly measure the measurement data of iron core coils, we provide a coil size detection device with a specific inner diameter, taking into account the characteristic that the inner diameter of the iron core coil is fixed during the production process.

[0007] frame;
[0008] A vertical platform, one side of which is rotatably mounted on a frame via a mounting base, and a first drive unit for driving the vertical platform to rotate from a horizontal position to a vertical position is installed between the frame and the vertical platform;
[0009] The vertical platform is equipped with forks for receiving coiled materials mounted vertically on its front.
[0010] A diameter rangefinder, which is installed directly below the conveyor forks;

[0012] In some embodiments, the forks are vertically slidably connected to the front of the vertical platform via a sliding mechanism. The forks are provided with detection positions via a first grooved photoelectric sensor on the sliding path of the vertical platform. When the forks carrying the coil slide to the detection position on the vertical platform, the width rangefinder and the diameter rangefinder start detecting the coil.
[0013] In some embodiments, the forks are provided with a bearing position via a second groove-shaped photoelectric sensor on the sliding path of the forks on the vertical platform;
[0014] The vertical platform is provided with a support tray frame at one end near the bottom, and the distance between the detection position and the inner wall of the support tray frame is not less than the maximum thickness of the roll material.
[0015] In some embodiments, the inner wall of the pallet support frame is set at an angle, and the center of the angle between the inner wall of the pallet support frame and the sliding trajectory of the forks are on the same straight line.
[0016] The support tray frame is designed with an opening at the position corresponding to the diameter rangefinder.
[0017] In some embodiments, the sliding mechanism includes a slide rail, a slider, and a second drive unit for the slider to move on the slide rail. The slide rail is vertically mounted on a vertical platform, the slider is slidably connected to the slide rail, and the fork is fixedly mounted on the front of the slider.
[0018] In some embodiments, the sliding mechanism is mounted on the back of the vertical platform, and the vertical platform has an actuation hole for the forks to pass through.
[0019] In some embodiments, the first drive unit includes a mounting arm and a servo cylinder, the servo cylinder being rotatably connected to the frame, and the telescopic end of the servo cylinder being rotatably connected to the mounting arm.

[0021] The vertical platform in the horizontal position has a mounting cavity between its back and the frame for installing the first drive unit, the second drive unit, and the sliding mechanism.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] 1. This utility model utilizes a width measuring instrument located directly in front of the vertical platform and a diameter measuring instrument located directly below the conveyor forks. By combining these with the adhesion between the roll material and the vertical platform, the size of the roll material can be effectively inspected. Furthermore, by rotating the roll material from a horizontal position to be in contact with the vertical platform, the adhesion between the roll material and the vertical platform is ensured. This effectively makes the inspection method suitable not only for standalone inspection conditions but also for conditions that require the roll material to be flipped from a horizontal position to a vertical position and the roll material size to be measured. Moreover, it can combine the above conditions to effectively reduce the number of steps in the warehousing process.
[0024] 2. This utility model utilizes a sliding fork on a vertical platform, combined with a support pallet frame. During the rotation of the coil from a horizontal to a vertical position, the support pallet frame reduces the coil's sliding distance, minimizing wear. Furthermore, the support pallet frame ensures the coil's positioning and alignment on the vertical platform, guaranteeing the bottom of the coil is directly above the diameter measuring instrument. The sliding fork then carries the coil to the detection position, maintaining a fixed bottom distance between the diameter measuring instrument and the inner diameter of the coil. This design, while adapting to the measurement method, reduces wear on the coil. Attached Figure Description

[0035] Example 1:
[0036] Please see Figures 1-2 ,
[0037] A device for detecting the inner diameter of a roll material includes: a frame 101, a vertical platform 102, a diameter measuring instrument 108, and a width measuring instrument 109.
[0038] One side of the vertical platform 102 is rotatably mounted on the frame 101 via the mounting base 103. A first drive unit 104 for driving the vertical platform 102 to rotate from a horizontal position to a vertical position is installed between the frame 101 and the vertical platform 102.
[0039] A fork 105 for receiving coiled material is vertically mounted on the front of the vertical platform 102; a diameter rangefinder 108 is mounted directly below the conveying fork 105; and a width rangefinder 109 is vertically mounted in front of the conveying vertical platform 102.
[0040] Working principle:
[0041] S1. In the initial state, the vertical platform 102 is placed horizontally by the first drive unit 104, so that the forks 105 are perpendicular to the vertical platform 102. Then, the coil is put on the forks 105. Then, the first drive unit 104 is activated to rotate the horizontal vertical platform 102 back to the vertical state. Under the action of gravity, the coil slides against the vertical platform 102 and is suspended on the forks 105.
[0042] S2. Then the width rangefinder 109 and the diameter rangefinder 108 are activated to detect the coil material.
[0043] S3. Since the distance between the width measuring instrument 109 and the vertical platform 102 is fixed and set as W1, the distance between the width measuring instrument 109 and the roll material is measured by the plane of the roll material and is W2. The width of the roll material is set as W. Calculate the width of the roll material W = W1 - W2.
[0044] Since the distance between the diameter measuring instrument 108 and the bottom of the inner diameter of the roll is fixed, let's call it D1. The distance between the diameter measuring instrument 108 and the roll is measured by the bottom of the roll by the diameter measuring instrument 108, which is D2. The inner diameter of the specific roll is D3. Let's call the diameter of the roll D. Calculate the diameter of the roll D = 2*(D1-D2)+D3.
[0045] S4. After measuring the width W and diameter D of the roll material, the PLC uploads the data to the warehousing system to complete the automatic entry of the roll material information.
[0046] In this embodiment, since one side of the roll material needs to be in contact with the front of the vertical platform 102 in order to measure the roll material by the width measuring instrument 109, the roll material is first placed on the vertical platform 102. Then, through the action of the vertical platform 102, the roll material is kept in a vertical state, and the contact between the roll material and the vertical platform 102 is ensured, thus effectively adapting to this measurement method. Moreover, this measurement method requires the roll material to be flipped from a horizontal state to a vertical state for effective measurement. Therefore, it is particularly suitable for some working conditions that require flipping the roll material from a horizontal state to a vertical state and measuring the size of the roll material.
[0047] As mentioned in the background art, during the warehousing process of iron core coils, it is necessary to first measure the dimensions of the horizontal coils, and then turn them vertically so that subsequent equipment such as palletizers can automatically clamp the coils for hanging storage. This method is well adapted to the above measurement method, which allows the coils to automatically fit onto the vertical platform 102 and slide onto the fixed position fork 105 after being turned over, thereby effectively measuring the coils through the width rangefinder 109 and the diameter rangefinder 108.
[0048] Both the width rangefinder 109 and the diameter rangefinder 108 are preferably laser rangefinders.
[0049] Example 2:
[0050] Please see Figure 1 , Figure 2 As a further improvement to Embodiment 1, unlike Embodiment 1, the fork 105 is vertically slidably connected to the front of the vertical platform 102 through the sliding mechanism 106. The fork 105 is provided with a detection position on the sliding path on the vertical platform 102 through the first groove-shaped photoelectric sensor 1013. When the fork 105 carries the coil and slides to the detection position on the vertical platform 102, the width rangefinder 109 and the diameter rangefinder 108 start to detect the coil.
[0051] The fork 105 has a bearing position on the sliding path on the vertical platform 102 via the second slotted photoelectric sensor 1014; the vertical platform 102 has a bearing pallet frame 1010 near the bottom, and the distance between the detection position and the inner wall of the bearing pallet frame 1010 is not less than the maximum thickness of the coil.
[0052] By limiting the position of the fork 105 when receiving the coil, and in conjunction with the setting of the carrying pallet frame 1010, the coil can be prevented from sliding on the front of the vertical platform 102 due to its own weight when it is flipped. This avoids the coil from having to slide a long distance to stop when it is hooked on the fork 105, thereby reducing the wear on the coil by reducing the sliding distance. Preferably, when the fork 105 is in the bearing position, the distance between the fork 105 and the carrying pallet frame 1010 is equal to the thickness of the coil. At this time, the coil will not slide during the process of rotating from the horizontal state to the vertical state.
[0053] The support pallet frame 1010 is set with an opening 1011 corresponding to the position of the diameter rangefinder 108.
[0054] Working principle:
[0055] S1. In the initial state, the vertical platform 102 is placed horizontally by the first drive unit 104. At this time, the forks 105 are located on the bearing position. Then, the coil is brought close to the inner wall of the bearing pallet frame 1010 and made to fit against the forks 105. Then, the coil is lowered so that the forks 105 can effectively guide the coil to be placed in the initial position of the vertical platform 102. In conjunction with the bearing pallet frame 1010, the coil sliding distance is reduced and the wear on the coil is reduced during the process of the coil rotating from the horizontal state to the vertical state.
[0056] Then, by starting the first drive unit 104, the horizontal vertical platform 102 is rotated and reset to the vertical state. During the rotation of the vertical platform 102, the coil material slides against the vertical platform 102 onto the support pallet frame 1010 under the action of gravity. Since the center of the support pallet frame 1010 coincides with the fork 105, when the center of the coil material is not in the same straight line as the sliding trajectory of the fork 105, the coil material will first contact one side of the support pallet frame 1010, and then move to the other side under the action of gravity and also fit against the support pallet frame 1010. This achieves the positioning correction of the coil material on the vertical platform 102, so that the center of the coil material coincides with the sliding path of the fork 105, ensuring that the bottom of the coil material is directly above the diameter rangefinder 108.
[0057] After the coil material is attached to both sides of the inner wall of the support pallet 1010, the fork 105 will move from the support position to the detection position. During the movement of the fork 105, the coil material will be moved upward to detach from the support pallet 1010, so that the inner diameter of the coil material is in a fixed position relative to the front of the vertical platform 102, thereby ensuring that the bottom distance between the diameter rangefinder 108 and the inner diameter of the coil material is fixed.
[0058] S2. Then the width rangefinder 109 and the diameter rangefinder 108 are activated to detect the coil material.
[0059] S3. Since the distance between the width measuring instrument 109 and the vertical platform 102 is fixed and set as W1, the distance between the width measuring instrument 109 and the roll material is measured by the plane of the roll material and is W2. The width of the roll material is set as W. Calculate the width of the roll material W = W1 - W2.
[0060] Since the distance between the diameter measuring instrument 108 and the bottom of the inner diameter of the roll is fixed, let's call it D1. The distance between the diameter measuring instrument 108 and the roll is measured by the bottom of the roll by the diameter measuring instrument 108, which is D2. The inner diameter of the specific roll is D3. Let's call the diameter of the roll D. Calculate the diameter of the roll D = 2*(D1-D2)+D3.
[0061] S4. After measuring the width W and diameter D of the roll material, the PLC uploads the data to the warehousing system to complete the automatic entry of the roll material information.
[0062] In this embodiment, the sliding mechanism 106 includes a slide rail 10601, a slider 10602, and a second drive unit 107 for the slider 10602 to move on the slide rail 10601. The slide rail 10601 is vertically mounted on the vertical platform 102. The slider 10602 is slidably connected to the slide rail 10601, and the fork 105 is fixedly mounted on the front of the slider 10602. The second drive unit 107 can be a lifting motor. When the second drive unit 107 is a lifting motor, the start of the lifting motor will cause the slider 10602 to move on the slide rail 10601 carrying the fork 105. Its detection position and bearing position can be controlled and confirmed by detecting the relative position of the slider 10602 through the first slotted photoelectric sensor 1013 and the second slotted photoelectric sensor 1014.
[0063] Alternatively, the second drive unit 107 in the sliding mechanism 106 may be a lifting electric cylinder, a rodless pneumatic rod, a linear motor, etc.
[0064] In this embodiment, the sliding mechanism 106 is installed on the back of the vertical platform 102, and the vertical platform 102 is provided with an active hole 1012 for the forks 105 to pass through, ensuring the flatness of the front of the vertical platform 102.
[0065] In this embodiment, the first drive unit 104 includes a mounting arm 10401 and a servo cylinder 10402. The servo cylinder 10402 is rotatably connected to the frame 101, and the telescopic end of the servo cylinder 10402 is rotatably connected to the mounting arm 10401. The first drive unit 104 is the servo cylinder 10402, and the vertical platform 102 is driven to rotate around the mounting base 103 by the extension or retraction of the servo cylinder 10402.
[0066] In this embodiment, a support frame 1015 is vertically fixedly connected to the side of the frame 101 away from the mounting base 103. The top of the support frame 1015 coincides with the back of the horizontal vertical platform 102 and is used to support the horizontal vertical platform 102. A mounting cavity is provided between the back of the horizontal vertical platform 102 and the frame 101 for mounting the first drive unit 104, the second drive unit 107, and the sliding mechanism 106.

Various modifications and variations can be made to this utility model by those skilled in the art.
