Description

Technical Field

[0001] This invention relates to the field of material handling technology, and in particular to an automatic material handling device for processing alloy bars. Background Technology

[0002] Alloy bars are a broad range of raw materials, not only diverse in type but also widely applicable, most commonly used in drills, milling cutters, and reamers. Further processing of alloy bars requires transfer, but their unique shape makes this transfer relatively difficult. Excessive clamping can damage the bar, while insufficient clamping may result in it falling. Current alloy bar loading and unloading devices primarily use gripper structures. Firstly, this gripping method is inherently unstable. Secondly, the gripping process may damage the surface of the alloy bar, affecting the accuracy of subsequent processing and potentially even impacting the usability of the finished product, leading to serious consequences. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: an automatic loading and unloading device for processing alloy bars, comprising a base device, the base device including a base plate, the base device being used to place the alloy bars, the base device being provided with a transfer device, a loading device, and an unloading device, the transfer device including a rotating seat fixedly mounted on the base plate, the transfer device being used to carry the alloy bars for transfer, the loading device including a loading rack fixedly mounted on the base plate, the loading device being used to feed the alloy bars into the processing area, the unloading device including an unloading rack fixedly mounted on the base plate, the unloading device being used to place the processed alloy bars onto the transfer device.

[0004] Furthermore, the base device includes a bar feeding box fixedly installed on the base plate, a bar support fixedly installed on the bar feeding box, a bar output frame fixedly installed on the base plate, and a bar output slope provided on the bar output frame.

[0005] The alloy bars to be processed are stacked in the bar box. The bottom bar will be placed on the bar support, and the subsequent bars will be arranged in sequence on the bar box. After the transfer device removes the bar from the bar support, the next alloy bar to be processed in the bar box will roll onto the bar support through the inclined plane.

[0006] The transfer device places the processed alloy rods onto the rod exit rack, and they leave the device via the rod exit ramp.

[0007] Furthermore, the circulation device includes a rotary motor fixedly mounted on a rotating base, a motor gear fixedly mounted on the motor shaft of the rotary motor, a central rotating base rotatably mounted on the rotating base, a central gear fixedly mounted on the central rotating base, the motor gear meshing with the central gear, a rotating arm motor fixedly mounted on the central rotating base, a rotating arm gear fixedly mounted on the motor shaft of the rotating arm motor, a large arm rotatably mounted on the central rotating base, an internal gear fixedly mounted on the large arm, an external gear rotatably mounted on the internal gear, the rotating arm gear meshing with the internal gear, the rotating arm gear meshing with the external gear, and a small arm mechanism provided on the large arm.

[0008] Furthermore, the forearm mechanism includes a forearm rotatably mounted on the upper arm, a forearm gear fixedly mounted on the forearm, a transmission belt wrapped around the forearm gear and the external gear, a rotating block rotatably mounted on the forearm, a transfer rod support fixedly mounted on the rotating block, and a gravity ball fixedly mounted below the rotating block.

[0009] Furthermore, the module of the internal gear is the same as that of the external gear, but the number of teeth of the internal gear is different from that of the external gear.

[0010] The rotating motor drives the motor gear to rotate, which in turn drives the central gear and the central rotating base to rotate relative to the rotating base. This causes the upper arm and lower arm to rotate as a whole, moving the transfer bar support below the support. The rotating arm motor drives the rotating arm gear to rotate, which in turn drives the inner gear and the upper arm to rotate, causing the upper arm to rotate and lift around the central rotating base. At the same time, the rotation of the rotating arm gear drives the rotation of the outer gear. Since the outer gear and the inner gear have different numbers of teeth, they rotate relative to each other. This drives the lower arm gear and the lower arm to rotate via the transmission belt, causing the lower arm to rotate upward relative to the upper arm. The transfer bar support lifts the alloy bar on the support. The gravity ball has a certain weight and is used to keep the support opening of the transfer bar support always facing upward.

[0011] After the transfer bar holder lifts the alloy bar, the rotary motor rotates, driving the motor gear to rotate, which in turn drives the central rotating seat to rotate. The transfer bar holder carries the alloy bar to the top of the lower pressure plate, and then the transfer bar holder places the alloy bar into the fixed bar holder.

[0012] Furthermore, the feeding device includes an electric cylinder fixedly installed on the feeding frame, a push rod fixedly installed on the top of the electric cylinder, a fixed rod support fixedly installed on the feeding frame, a pressing rod slidably installed on the fixed rod support, an outer spring provided between the pressing rod and the feeding frame, and a triggering mechanism provided on the feeding frame.

[0013] Furthermore, the triggering mechanism includes a fixed block fixedly installed on the feeding rack, a sensing plate fixedly installed on the fixed block, a downward pressure spring fixedly installed inside the fixed block, a downward pressure plate fixedly installed on the top of the downward pressure spring, and the downward pressure plate located below the downward pressure rod.

[0014] After the transfer device places the alloy bar onto the fixed bar holder, the alloy bar falls onto the lower pressure rod. The weight of the alloy bar presses the lower pressure rod downward, compressing the outer spring. After the lower pressure rod contacts the lower pressure plate, it drives the lower pressure plate to descend, compressing the lower pressure spring. When the lower pressure plate contacts the sensor plate, the electric cylinder extends, driving the push rod forward. The push rod pushes the alloy bar on the fixed bar holder to the processing area.

[0015] Furthermore, the feeding device includes a feeding motor fixedly mounted on a feeding frame, a motor wheel fixedly mounted on the motor shaft of the feeding motor, a limit bracket fixedly mounted on the feeding frame, a transmission wheel rotatably mounted on the limit bracket, a friction belt wrapped around the transmission wheel, the friction belt cooperating with the motor wheel, a fixed frame fixedly mounted on the feeding frame, a sliding disc slidably mounted on the fixed frame, and a compression spring provided between the sliding disc and the friction belt.

[0016] The processed alloy bar is placed on the friction belt. At this time, the transfer bar support moves between the limit support and the fixed frame. The feeding motor rotates, driving the motor wheel to rotate, which in turn drives the friction belt to transport the processed alloy bar towards the sliding plate. When the alloy bar contacts the sliding plate, the friction belt drives the alloy bar to continue moving forward, which will cause the sliding plate to slide in the fixed frame. The compression spring is compressed. When the sliding plate contacts the sensor plate, the rotating arm motor rotates, driving the upper arm and the lower arm to lift the transfer bar support. Then the rotary motor rotates, driving the central rotating seat to rotate around the rotating seat, placing the processed alloy bar on the bar exiting frame, and leaving the device through the bar exiting ramp.

[0017] The beneficial effects of the present invention compared with the prior art are: (1) The transfer device set in the present invention drives the upper arm and the lower arm to rotate simultaneously through the rotating arm motor, thereby realizing the preset motion trajectory, taking the alloy bar off the bar holder, placing the alloy bar in the loading device, and taking the processed alloy bar out of the unloading device, with a high degree of automation; (2) The transfer bar holder of the transfer device set in the present invention can hold the alloy bar, thereby driving the alloy bar to transfer to different work positions, and through the gravity ball, the opening of the transfer bar holder is always facing upward, realizing reliable transfer of the alloy bar, and without damaging the surface of the alloy bar; (3) The setting of the bar holder and the bar feeding box on the base device set in the present invention enables the transfer device to drive one alloy bar to transfer each time, and the next alloy bar automatically arrives on the bar holder.

Detailed Implementation

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0030] Example: Reference Figures 1-10An automatic loading and unloading device for processing alloy bars includes a base device, which includes a base plate 101. The base device is used to place the alloy bars into the base. The base device is equipped with a transfer device, a loading device, and an unloading device. The transfer device includes a rotating seat 201, which is fixedly installed on the base plate 101. The transfer device is used to carry the alloy bars for transfer. The loading device includes a loading rack 301, which is fixedly installed on the base plate 101. The loading device is used to feed the alloy bars into the processing area. The unloading device includes an unloading rack 401, which is fixedly installed on the base plate 101. The unloading device is used to place the processed alloy bars onto the transfer device.

[0031] like Figure 2 As shown, the base device includes a bar feeding box 102 fixedly installed on the base plate 101, a bar support 103 fixedly installed on the bar feeding box 102, a bar output frame 104 fixedly installed on the base plate 101, and a bar output slope 105 provided on the bar output frame 104.

[0032] The alloy bars to be processed are stacked in the bar feeding box 102. The bottom bar will be located on the bar support 103, and the subsequent bars will be arranged in sequence on the bar feeding box 102. When the transfer device removes the bar on the bar support 103, the next alloy bar to be processed in the bar feeding box 102 will roll onto the bar support 103 through the inclined plane.

[0033] The transfer device places the processed alloy rods onto the rod exit rack 104, and they leave the device via the rod exit ramp 105.

[0034] like Figures 3-5 As shown, the transfer device includes a rotary motor 202 fixedly mounted on a rotary base 201. A motor gear 203 is fixedly mounted on the motor shaft of the rotary motor 202. A central rotary base 205 is rotatably mounted on the rotary base 201. A central gear 204 is fixedly mounted on the central rotary base 205. The motor gear 203 meshes with the central gear 204. A rotating arm motor 206 is fixedly mounted on the central rotary base 205. A rotating arm gear 207 is fixedly mounted on the motor shaft of the rotating arm motor 206. A large arm 208 is rotatably mounted on the central rotary base 205. An internal gear 209 is fixedly mounted on the large arm 208. An external gear 210 is rotatably mounted on the internal gear 209. The rotating arm gear 207 meshes with the internal gear 209 and the external gear 210. A small arm mechanism is provided on the large arm 208.

[0035] like Figures 3-5As shown, the forearm mechanism includes a forearm 213 rotatably mounted on the upper arm 208, a forearm gear 212 fixedly mounted on the forearm 213, a transmission belt 211 wrapped around the forearm gear 212 and the external gear 210, a rotating block 214 rotatably mounted on the forearm 213, a transfer rod support 215 fixedly mounted on the rotating block 214, and a gravity ball 216 fixedly mounted below the rotating block 214.

[0036] like Figures 3-5 As shown, the module of the internal gear 209 is the same as that of the external gear 210, and the number of teeth of the internal gear 209 is different from that of the external gear 210.

[0037] Rotating motor 202 drives motor gear 203 to rotate, which in turn drives central gear 204 and central rotating base 205 to rotate relative to rotating base 201. This causes the upper arm 208 and lower arm 213 to rotate as a whole, moving the transfer bar support 215 below the support 103. Rotating arm motor 206 drives rotating arm gear 207 to rotate, which in turn drives internal gear 209 and upper arm 208 to rotate. This causes the upper arm 208 to rotate and lift around the central rotating base 205. At the same time, rotating arm gear 204 rotates. The rotation of 07 will drive the external gear 210 to rotate. Since the number of teeth of the external gear 210 and the internal gear 209 are different, the external gear 210 and the internal gear 209 rotate relative to each other. Therefore, the transmission belt 211 drives the forearm gear 212 and the forearm 213 to rotate, thereby driving the forearm 213 to rotate upward relative to the upper arm 208. The transfer rod support 215 lifts the alloy rod on the rod support 103. The gravity ball 216 has a certain weight and is used to keep the support opening of the transfer rod support 215 always facing upward.

[0038] After the transfer bar holder 215 lifts the alloy bar, the rotary motor 202 rotates, driving the motor gear 203 to rotate, which in turn drives the central rotating seat 205 to rotate. The transfer bar holder 215 carries the alloy bar to the top of the lower pressure plate 306, and then the transfer bar holder 215 puts the alloy bar into the fixed bar holder 304.

[0039] like Figures 6-8 As shown, the feeding device includes an electric cylinder 302 fixedly installed on the feeding frame 301, a push rod 303 fixedly installed on the top of the electric cylinder 302, a fixed rod support 304 fixedly installed on the feeding frame 301, a pressing rod 305 slidably installed on the fixed rod support 304, an outer spring 308 is provided between the pressing rod 305 and the feeding frame 301, and a triggering mechanism is provided on the feeding frame 301.

[0040] like Figures 6-8As shown, the triggering mechanism includes a fixed block 309 fixedly installed on the feeding rack 301, a sensor plate 310 fixedly installed on the fixed block 309, a pressure spring 307 fixedly installed inside the fixed block 309, a pressure plate 306 fixedly installed on the top of the pressure spring 307, and the pressure plate 306 is located below the pressure rod 305.

[0041] After the transfer device places the alloy bar onto the fixed bar holder 304, the alloy bar falls onto the lower pressure rod 305. The weight of the alloy bar presses the lower pressure rod 305 downward, compressing the outer spring 308. After the lower pressure rod 305 contacts the lower pressure plate 306, it drives the lower pressure plate 306 to descend, compressing the lower pressure spring 307. When the lower pressure plate 306 contacts the sensor plate 310, the electric cylinder 302 extends, driving the push rod 303 forward. The push rod 303 pushes the alloy bar on the fixed bar holder 304 to the processing area.

[0042] like Figure 9 , Figure 10 As shown, the feeding device includes a feeding motor 402 fixedly mounted on a feeding frame 401. A motor wheel 403 is fixedly mounted on the motor shaft of the feeding motor 402. A limit support 404 is fixedly mounted on the feeding frame 401. A transmission wheel 409 is rotatably mounted on the limit support 404. A friction belt 405 is wound around the transmission wheel 409. The friction belt 405 cooperates with the motor wheel 403. A fixing frame 406 is fixedly mounted on the feeding frame 401. A sliding disc 407 is slidably mounted on the fixing frame 406. A compression spring 408 is provided between the sliding disc 407 and the friction belt 405.

[0043] The processed alloy bar is placed on the friction belt 405. At this time, the transfer bar support 215 moves between the limit support 404 and the fixed frame 406. The feeding motor 402 rotates, driving the motor wheel 403 to rotate, thereby driving the friction belt 405 to transport the processed alloy bar towards the sliding plate 407. When the alloy bar contacts the sliding plate 407, the friction belt 405 drives the alloy bar to continue moving forward, which will cause the sliding plate 407 to slide in the fixed frame 406. The compression spring 408 is compressed. When the sliding plate 407 contacts the sensor plate 410, the rotating arm motor 206 rotates, driving the upper arm 208 and the lower arm 213 to lift the transfer bar support 215. Then the rotary motor 202 rotates, driving the central rotating seat 205 to rotate around the rotating seat 201, placing the processed alloy bar on the bar exit frame 104, and leaving the device through the bar exit ramp 105.

[0044] The working principle of the automatic loading and unloading device for alloy bar processing disclosed in this invention is as follows: Alloy bars to be processed are stacked in the bar feeding box 102, with the bottom bar located on the bar support 103, and subsequent bars arranged sequentially on the bar feeding box 102. After the transfer device removes the bar from the bar support 103, the next alloy bar to be processed in the bar feeding box 102 rolls onto the bar support 103 via an inclined plane. The rotary motor 202 rotates, driving the motor gear 203 to rotate, thereby causing the central gear 204 and the central rotating seat 205 to rotate relative to the rotating seat 201, thus causing the upper arm 208 and the lower arm 213 to rotate as a whole, moving the transfer bar support 215 below the bar support 103. The rotating arm motor 206 rotates, driving the rotating arm gear 207 to rotate, thereby driving the internal gear 209 and the upper arm 208 to rotate, thus causing the upper arm 208 to rotate and lift around the central rotating seat 205. Simultaneously, the rotating arm gear 204 rotates... Rotation of gear 07 drives external gear 210 to rotate. Since external gear 210 and internal gear 209 have different numbers of teeth, they rotate relative to each other. This causes transmission belt 211 to drive the forearm gear 212 and forearm 213 to rotate, thereby causing the forearm 213 to rotate upwards relative to the upper arm 208. The transfer rod support 215 lifts the alloy rod on the rod support 103. Gravity ball 216, with its weight, keeps the support opening of the transfer rod support 215 always facing upwards. After the transfer rod support 215 lifts the alloy rod, the rotary motor 202 rotates, driving the motor gear 203 to rotate, which in turn drives the central rotating seat 205 to rotate. The transfer rod support 215 then moves the alloy rod above the lower pressure plate 306, and finally places it into the fixed rod support 304. After the transfer device places the alloy bar onto the fixed bar holder 304, the alloy bar falls onto the lower pressure rod 305. The weight of the alloy bar presses the lower pressure rod 305 downward, compressing the outer spring 308. After the lower pressure rod 305 contacts the lower pressure plate 306, it drives the lower pressure plate 306 to descend, compressing the lower pressure spring 307. When the lower pressure plate 306 contacts the sensor plate 310, the electric cylinder 302 extends, driving the push rod 303 forward. The push rod 303 pushes the alloy bar on the fixed bar holder 304 to the processing area.The processed alloy bar is placed on the friction belt 405. At this time, the transfer bar support 215 moves between the limit support 404 and the fixed frame 406. The feeding motor 402 rotates, driving the motor wheel 403 to rotate, thereby driving the friction belt 405 to transport the processed alloy bar towards the sliding plate 407. When the alloy bar contacts the sliding plate 407, the friction belt 405 drives the alloy bar to continue moving forward, which will cause the sliding plate 407 to slide in the fixed frame 406. The compression spring 408 is compressed. When the sliding plate 407 contacts the sensor plate 410, the rotating arm motor 206 rotates, driving the upper arm 208 and the lower arm 213 to lift the transfer bar support 215. Then the rotary motor 202 rotates, driving the central rotating seat 205 to rotate around the rotating seat 201, placing the processed alloy bar on the bar exit frame 104, and leaving the device through the bar exit ramp 105.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
